A constant theme of this blog is that the NHS should not pay for useless treatments. By and large, NICE does a good job of preventing that. But NICE has not been allowed by the Department of Health to look at quackery.
I have the impression that privatisation of many NHS services will lead to an increase in the provision of myth-based therapies. That is part of the "bait and switch" tactic that quacks use in the hope of gaining respectability. A prime example is the "College of Medicine", financed by Capita and replete with quacks, as one would expect since it is the reincarnation of the Prince’s Foundation for Integrated Health.
One such treatment is acupuncture. Having very recently reviewed the evidence, we concluded that "Acupuncture is a theatrical placebo: the end of a myth". Any effects it may have are too small to be useful to patients. That’s the background for an interesting case study.
A colleague got a very painful frozen shoulder. His GP referred him to the Camden & Islington NHS Trust physiotherapy service. That service is now provided by a private company, Connect Physical Health.
That proved to be a big mistake. The first two appointments were not too bad, though they resulted in little improvement. But at the third appointment he was offered acupuncture. He hesitated, but agreed, in desperation to try it. It did no good. At the next appointment the condition was worse. After some very painful manipulation, the physiotherapist offered acupuncture again. This time he refused on the grounds that "I hadn’t noticed any effect the first time, because there is no evidence that it works and that I was concerned by her standards of hygiene". The physiotherapist then became "quite rude" and said that she would put down that the patient had refused treatment.
The lack of response was hardly surprising. NHS Evidence says
In fact it now seems beyond reasonable doubt that acupuncture is no more than a theatrical placebo.
According to Connect’s own web site “Our services are evidence-based”. That is evidently untrue in this case, so I asked them for the evidence that acupuncture was effective.
I’d noticed that in other places, Connect Physical Health also offers the obviously fraudulent craniosacral therapy (for example, here) and discredited chiropractic quackery. So I asked them about the evidence for their effectiveness too.
This is what they said.
Many thanks for your comments via our web site. In response, we thought you might like to access the sources for some of the evidence which underpins our MSK services:
Integrating Evidence-Based Acupuncture into Physiotherapy for the Benefit of the Patient – you can obtain the information you require from www.aacp.org.uk
The General Chiropractic Council www.gcc-uk.org/page.cfm
We have also attached a copy of the NICE Guidelines.
So, no Cochrane reviews, no NHS Evidence. Instead I was referred to the very quack organisations that promote the treatments in question, the Acupuncture Association of Chartered Physiotherapists, and the totally discredited General Chiropractic Council.
The NICE guidelines that they sent were nothing to do with frozen shoulder. They were the guidelines for low back pain which caused such a furore when they were first issued (and which, in any case, don’t recommend chiropractic explicitly).
When I pointed out these deficiencies I got this.
Your email below has been forwarded to me. I am sorry if you feel that that that information we pointed you towards to enable you to make your own investigations into the evidence base for the services provided by Connect Physical Health and your hospital did not meet with your expectations.
‘ ‘ ‘
Please understand that our NHS services in Camden were commissioned by the Primary Care Trust. The fully integrated MSK service model included provision for acupuncture and other manual therapy provided by our experienced Chartered Physiotherapists. If you have any problems with the evidence base for the use of acupuncture or manual therapy within the service, which has been commissioned on behalf of the GPs in Camden Borough, then I would politely recommend that you direct your observations to the clinical commissioning authorities and other professional bodies who do spend time evidencing best practice and representing the academic arguments. I am sure they will be pleased to pick up discussions with you about the relative merits of the interventions being procured by the NHS.

So, "don’t blame us, blame the PCT". A second letter asked why they were shirking the little matter of evidence.
In response to your last email, I would like to say that Connect does not wish to be drawn into a debate over two therapeutic options (acupuncture and craniosacral therapy) that are widely practiced [sic] within and outside the NHS by very respectable practitioners.
You will be as aware, as Connect is, that there are lots of treatments that don’t have a huge evidence base that are practiced in mainstream medicine. Connect has seen many carefully selected patients helped by acupuncture and manual therapy (craniosacral therapy / chiropractic) over many years. Lack of evidence doesn’t mean they don’t work, just that benefit is not proven. Furthermore, nowhere on our website do we state that ALL treatments / services / modalities that Connect offer are ‘Evidence Based’. We do however offer many services that are evidence based, where the evidence exists. We aim to offer ‘choice’ to patients, from a range of services that are safe and delivered by suitably trained professionals and practitioners in line with Codes of Practice and Guidelines from the relevant governing bodies.
Connect’s service provision in Camden is meticulously assessed and of a high standard and we are proud of the services provided.
This response is so wrong, on so many levels, that I gave up on Mr Philpott at this point. At least he admitted implicitly that all of their treatments are not evidence-based. In that case their web site needs to change that claim.
If, by "governing bodies" he means jokes like the GCC or the CNHC then I suppose the behaviour of their employees is not surprising. Mr Philpott is evidently not aware that "craniosacral therapy" has been censured by the Advertising Standards Authority. Well he is now, but evidently doesn’t seem to give a damn.
Next I wrote to the PCT and it took several mails to find out who was responsible for the service. Three mails produced no response so I sent a Freedom of Information Act request. In the end I got some
"Connect PHC provide the Community musculoskeletal service for Camden. The specification for the service specifically asks for the provision of evidence based management and treatments see paragraph on Governance page 14 of attached.. Patients are treated with acupuncture as per the NICE Guidelines (May 2009) for the management of low back pain … . .. Chiropractors are not employed in the service and craniosacral therapy is not provided as part of the service either."
Another letter, pointing out that they were using acupuncture for things other than low back pain got no more information. They did send a copy of the contract with Connect. It makes no mention whatsoever of alternative treatments. It should have done, so part of the responsibility for the failure must lie with the PCT.
The contract does, however, say (page 18)
The service to be led by a lead clinician/manager who can effectively demonstrate ongoing and evidence-based development of clinical guidelines, policies and protocols for effective working practices within the service
In my opinion, Connect Physical Health are in breach of contract
Another example of Connect ignoring evidence
The Connect Physical Health web site has an article about osteoarthritis of the knee
Physiotherapy can be extremely beneficial to help to reduce the symptoms of OA. Treatments such as mobilizations, rehab exercises, acupuncture and taping can help to reduce pain, increase range of movement, increase muscle strength and aid return to functional activities and sports.
There is little enough evidence that physiotherapy does any of these things, but at least it is free of mystical mumbo-jumbo. Although at one time the claim for acupuncture was thought to have some truth, the 2010 Cochrane review concludes otherwise
Sham-controlled trials show statistically significant benefits; however, these benefits are small, do not meet our pre-defined thresholds for clinical relevance, and are probably due at least partially to placebo effects from incomplete blinding.
This conclusion is much the same as has been reached for acupuncture treatments of almost everything. Two major meta-analyses come to similar conclusions. Madsen Gøtzsche & Hróbjartsson (2009) and Vickers et al (2012) both conclude that if there is an effect at all (dubious) then it is too small to be noticeable to the patient. (Be warned that in the case of Vickers et al. you need to read the paper itself because of the spin placed on the results in the abstract.). These papers are discussed in detail in our recent paper.
Why is Connect Physical Health not aware of this?
Their head of operations told me (see above) that
"Connect does not wish to be drawn into a debate [about acupuncture and craniosacral therapy]".
That outlook was confirmed when I left a comment on their osteoarthritis post. This is what it looked like almost a month later.
Guess what? The comment has never appeared..
The attitude of Connect Physical Health to evidence is simply to ignore it if it gets in the way of making money, and to censor any criticism.
What have Camden NHS done about it?
The patient and I both complained to Camden NHS in August 2012. At first, they simply forwarded the complaints to Connect Physical Health with the unsatisfactory results shown above. It took until May 2013 to get any sort of reasonable response. That seems a very long time. In fact by the time the response arrived the PCT had been renamed a Clinical Commissioning Group (CCG) because of the vast top-down reorganisation inposed by Lansley’s Health and Social Care Act.
On 8 May 2013, this response was sent to the patient, Here is part of it.
I have received your email of complaint from the NHSNCL complaints department regarding your care.
You raise some very clear concerns and I will attempt to address these in order.
1) The fact that you felt pressurised into having acupuncture is a concern as everybody should be given a choice. As part of the informed consent relating to acupuncture you should have been told about the treatment, it’s [sic] benefits and risks and then you sign to confirm you are happy to proceed. I understand that this was the case in your situation but I have reinforced that the consent is important and must be adhered to by the provider Connect Physical Health. There are clear standards of clinical practice that all Chartered Physiotherapists must follow which I will discuss further with the Connect Camden team Manager Nick Downing.
I do disagree with you around acupuncture; there is no conclusive evidence for acupuncture in frozen shoulder but I have referenced a systematic review which concludes the studies were too small to draw any conclusions although shoulder function was significantly improved at 4 weeks (Green S et al. Acupuncture for shoulder pain. Cochrane Database Syst Rev 2005; 18: CD005319). There is a growing body of evidence supporting the use of acupuncture and until such time as there is specific evidence against it I don’t think we would be absolutely against the practice of this modality alongside other treatments.
Strategy and Planning Directorate
This response raises more questions than it answers.
For example, what is "informed consent" worth if the therapist is his/herself misinformed about the treatment? It is the eternal dilemma of alternative medicine that it is no use referring to well-trained practitioners, when their training has inculcated myths and untruths.
There is not a "growing body of evidence supporting the use of acupuncture". Precisely the opposite is true.
And the statement "until such time as there is specific evidence against it I don’t think we would be absolutely against the practice of this modality alongside" betrays a basic misunderstanding of the scientific process.
So I sent the writer of this letter a reprint of our paper, "Acupuncture is a theatrical placebo: the end of a myth" (the blog version alone has had over 12,000 page views). A few days later we had an amiable lunch together and we had a constructive discussion about the problems of deciding what should be commissioned and what shouldn’t.
It seems to me to be clear that CCGs should take better advice before boasting that they commission evidence-based treatments.
Stories like this are worrying to the majority of physiotherapists who don’t go in for mystical mumbo-jumbo of acupuncture. One of the best is Neil O’Connell who blogs at BodyInMind. He tweeted
— Neil O'Connell (@NeilOConnell) June 10, 2013
It isn’t clear how many physiotherapists embrace nonsense, but the Acupuncture Association of Chartered Physiotherapists has around 6000 members, compared with 47,000 chartered physiotherapists (AACP), so it’s a smallish minority. The AACP claims that it is “Integrating Evidence-Based Acupuncture into Physiotherapy”. Like most politicians, the term “evidence-based” is thrown around with gay abandon. Clearly they don’t understand evidence.
12 June 2013
The Advertising Standards Authority has, one again, upheld complaints against the UCLH Trust, for making false claims in its advertising. This time, appropriately, it’s about acupuncture. Just about everything in their advertising leaflets was held to be unjustifiable. They’ve been in trouble before about false claims for homeopathy, hypnosis and craniosacral "therapy".
Of course all of these embarrassments come from one very small corner of the UCLH Trust, the Royal London Hospital for Integrated Medicine (previously known as the Royal London Homeopathic Hospital).
Why is it tolerated in an otherwise excellent NHS Trust? Well, the patron is the Queen herself (not Charles, aka the Quacktitioner Royal), She seems to exert more power behind the scenes than is desirable in In a constitutional monarchy
29 June 2013
I wrote to Dr Gill Gaskin about the latest ASA judgement against RLHIM. She is the person at the UCLH Trust who has responsibility for the quack hospital. She previously refused to do anything about the craniosacral nonsense that is promoted there. This time the ASA seems to have stung them into action at long last. I was told
In response to your question about proposed action:
All written information for patients relating to the services offered by the Royal London Hospital for Integrated Medicine are being withdrawn for review in the light of the ASA’s rulings (and the patient leaflets have already been withdrawn). It will be reviewed and modified where necessary item by item, and only reintroduced after sign-off through the Queen Square divisional clinical governance processes and the Trust’s patient information leaflet team.
With best wishes
Dr Gill Gaskin
It remains to be seen whether the re-written information is accurate or not.
The rules for advertising
The Advertising Standards Authority gives advice for advertisers about what’s permitted and what isn’t.
Acupuncture The CAP advice
Craniosacral therapy The CAP advice
Chiropractic The CAP advice.
We all know that chiropractors feel pretty desperate, after their job has been revealed as baseless (much more information at ebm-first). Nonetheless it was very surprising when I was alerted by Twitter to the fact that the London Chiropractors were claiming to have been chosen by UCL as a "Centre of Excellence".
That was the heading in the whole page devoted to crowing about this designation. The page, as it was on18th April, can be seen on freezepage.com. They even boast about our 21 Nobel prizewinners, as though they had endorsed chiropractic.
"London Chiropractor has recently been designated as a “Centre of Excellence” by University College London. The University is among the world’s leading universities as can be seen by its ranking in a variety of performance areas. Twenty-one Nobel prizewinners have come from the University’s community".
The triumphalist crowing goes on
"The designation of London Chiropractor as a Centre of Excellence is something that we are sincerely proud of. It distinguishes our clinic while providing impetus to carry on with our multi-disciplinary and evidence based treatment strategies while looking for new ways in which to improve on all aspects of our clinic at the same time and in a continuous manner."
But chiropractic is undoubtedly in deep trouble, after more that 600 complaints were submitted to the General Chiropractic Council (GCC). The GCC was forced to renounce what has always been a central myth of chiropractic, the "subluxation". The fact that most of the complaints have been rejected has revealed huge deficiencies in the GCC (some of which it recently admitted). It also reveals the uselessness of the Council for Health Regulatory Excellence (CHRE).which is meant to supervise them. More details at quackometer, Chiropractors at War with their Regulator, the GCC.
In the words of Richard Brown (president of the BCA) himself,
"The BCA sued Simon Singh personally for libel. In doing so, the BCA began one of the darkest periods in its history; one that was ultimately to cost it financially,"
Needless to say, chiropractors are trying to cash in on the Olympic games, sadly, with a little success. I suppose that invoking UCL. was part of that attempt. Like so many of chiropractors’ attempts to defend themselves, it misfired badly.
The inspection of evidence that followed the attempt by the British Chiropractic Association (BCA) to sue Simon Singh showed that he was entirely justified to describe many of their treatments as “bogus” and “without a jot of evidence”.
A quick email to the UCL authorities quickly determined that the claimed endorsement was not true. Attempting to access this page now leads to “page not found". The page vanished on Sunday 22nd April, and a near identical page for the Broadgate Spine and Joint Clinic had already vanished on Friday 20th April. While it is true that two surgeons from UCL’s Institute of Sports Medicine have worked in the same building, they neither use chiropractic nor endorse it.
I’m assured that the alleged endorsement never happened. London Chiropractors won’t say where it came from. It seems that it was simply made up. I think that’s called a lie. I presume it is a sign of the desperation of chiropractors.
Since writing about anti-scientific degrees in Nature (March 2007), much has been revealed about the nonsense that is taught on these degrees. New Year’s day seems like a good time to assess how far we’ve got, five years on.
At the beginning of 2007 UCAS (the universities central admission service) offered 45 different BSc degrees in quackery, at 16 universities.
Now there are only 24 such degrees.
If you exclude chiropractic and osteopathy, which all run at private colleges, with some sort of "validation" from a university, there are now only 18 BSc/MSc courses being offered in eight universities.
Degrees in homeopathy, naturopathy and "nutritional therapy", reflexology and aromatherapy have vanished altogether from UCAS.
In the race to provide BScs in anti-science, Middlesex University has now overhauled the long-standing leader, Westminster, by a short head.
Michael Driscoll, vice-chancellor of Middlesex
Let’s see what’s gone.
The University of Central Lancashire (UCLAN) was the first to see sense. In August 2008 they announced closure of their “BSc” degree in homeopathy. On September 2008 they announced an internal review of their courses in homeopathy. herbalism and acupuncture. The report of this review closed down all of them in July 2009. I first asked for their teaching materials in July 2006. I finally got them in December 2010, after winning an appeal to the Information Commissioner, and then winning an appeal against that decision at an Information tribunal . By the time I got them, the course had been closed for over two years. That is just as well, because it turned out that UCLAN’s students were being taught dangerous nonsense. No wonder they tried so hard to conceal it.
Salford University was the next to go. They shut down their courses in complementary medicine, homeopathy and acupuncture. In January 2009 they announced " they are no longer considered “a sound academic fit” ". Shortly afterwards. a letter appeared in The Times from three heavyweights (plus me) congratulating the vice-chancellor on his decision.
University of Westminster
For many years, Westminster was the biggest supplier of BSc degrees in quackery. At the beginning of 2007 they offered 14 different BSc degrees in homeopathy, naturopathy, nutritional therapy, "complementary therapies", (western) herbal medicine and traditional Chinese medicine with acupuncture. Some of their courses were so bizarre that some of the students and even staff sent me slides which taught things like "amethysts emit high Yin energy". Like UCLAN, Westminster also held an internal review. Unlike UCLAN it came to the absurd conclusion that all would be well if they injected more science into the courses. The incompetence of the review meant that those who wrote it hadn’t noticed that if you try to put science into homeopathy or naturopathy, the whole subject vanishes in a puff of smoke. Nevertheless Westminster closed down entry to BSc homeopathy in March 2009 (though the subject remained as part of other courses).
Three years after the Nature article, all five BSc homeopathy degrees had shut their doors.
During 2011, Westminster shut down Naturopathy, Nutritional therapy, Therapeutic bodywork and Complementary Medicine. See, for example,
More dangerous nonsense from the University of Westminster: when will Professor Geoffrey Petts do something about it?
Now Westminster has only four courses in two subjects. They still teach some dangerous and untrue things, but I suspect the writing is on the wall for these too.
I have seen a document, dated 11 April 2011, which states
“The following courses have been identified as ‘at risk’ (School definition) and will be discussed at the APRG and University Review Group2, due to poor recruitment and high cost of delivery:
Integrated Health Scheme: BSc Complementary Medicine, Naturopathy; BSc Chinese Medicine; BSc Nutritional Therapy; BSc Herbal Medicine”
All but Chinese medicine and Herbal medicine have already gone. Almost there.
University of Wales
Since my first post in 2008 about the validation scam operated by the University of Wales, and some good investigations by BBC Wales TV, the outcome was the most spectacular so far. The entire institution collapsed. They no longer "validate" external degrees at dodgy business colleges, loony religious colleges or magic medicine colleges.
Another worthless validation: the University of Wales and nutritional therapy (October 2008) This is a ‘degree’ in nutrtional therapy. It is even more hilarious than usual, but it passed the validation anyway.
Scandal of the University of Wales and the Quality Assurance Agency (November 2010). This post followed the BBC Wales TV programme. At last the QAA began to notice, yet further confirmation of its utter ineptitude.
The University of Wales disgraced (but its vice chancellor is promoted) (October, 2011) The eventual collapse of the university was well-deserved. But it is very weird that the people who were responsible for it have still got their jobs. In fact the vice-chancellor, Marc Clement, was promoted despite his mendacious claim to be unaware of what was going on.
It remains to be seen how many of the many quack courses that were validated by the University of Wales will be taken on by other universities. The McTimoney College of Chiropractic is owned by BPP University (so much for their quality control, as explained in Private Eye). but still claims to be validated by Wales until 2017.
Some of the more minor players
Edinburgh Napier University. After an FOI request (rejected), Napier closed their herbal medicine degree in 2010.
As expected, the Scottish Information Commissioner agreed with that for England and Wales and ordered material to be sent. Edinburgh Napier University teaches reflexology, aromatherapy and therapeutic touch. Scottish Information Commissioner says you should know. Some of the horrors so discovered appeared in Yet more dangerous nonsense inflicted on students by Edinburgh Napier University. The embarrassment seems to have worked. Their remaining degrees in aromatherapy and reflexology have now vanished from UCAS too. All that remains is a couple of part time “Certificates of Credit” for aromatherapy and reflexology
Anglia Ruskin Univerity Not only have BSc degrees gone in aromatherapy and reflexology, but their midwifery degree now states "We are unable to accept qualifications in aromatherapy, massage and reflexology."
University of Derby Reflexology and aromatherapy have gone, though doubtless Spa management therapies have much nonsense left
University of Greenwich. BSc in Complementary Therapies (Nutritional Health) and BSc in Complementary Therapies (Nutritional Health) have been shut. The BSc Acupuncture is listed on their web site but it is under review, and is not listed in UCAS for 2012. (Acupuncture is run at International College of Oriental medicine, validated by Greenwich.). Only osteopathy (MOst) is still running, and that is a validation of an external course run at The European School of Osteopathy, in Maidstone
Thames Valley University was renamed the University of West London in 2010. The nonsense that was run there (e.g. Nutritional Fairy Tales from Thames Valley University) seems to have vanished. Their previous alt med guru, Nicola Robinson, appears now to be at London South Bank University (ranked 116 out of the 116 UK universities)
Chiropractic Surprisingly, given the total discreditation of chiropractic in the wake of the Simon Singh affair, and the internecine warfare that followed it, none of the chiropractic courses have shut yet. Some are clearly in trouble, so watch this space.
Osteopathy has also had no course closures since 2007. Like chiropractic it also suffers from internecine warfare. The General Osteopathic Council refuses to disown the utter nonsense of "craniosacral" osteopathy. But the more sensible practitioners do so and are roughly as effective as physiotherapists (though there are real doubts about how effective that is).
Excluding chiropractic and osteopathy, this is all that’s left. It now consists almost entirely of Chinese medicine and a bit of herbal.
Glyndwr university (Known as North East Wales Institute until 2008) Ranked 104 out of 116 UK universities

Cardiff Metropolitan University (UWIC) (Known as University of Wales Institute Cardiff (UWIC) until Nov 2011.) The vice-chancellor of Cardiff Metropolitan, Antony Chapman, is in the QAA’s board of directors, so perhaps it isn’t surprising that the QAA has done nothing.

It seems that acupuncture hangs on in universities that are right at the bottom of the rankings.
Manchester Metropolitan gets the booby prize for actually starting a new course, just as all around are closing theirs. Dr Peter Banister, who was on the committee that approved the course (but now retired), has told me ” I am sceptical in the current economic climate whether it will prove to be successful”. Let’s hope he’s right.
But well done Westminster. Your position as the leader in antiscientific degrees has now been claimed by Middlesex University. Their "degrees" in Ayurveda mark out Middlesex University as the new King of Woo.
Over to you, Professor Driscoll. As vice-chancellor of Middlesex University, the buck stops with you.
Both still teach Chinese and herbal medicine, which are potentially dangerous. There is not a single product from either that has marketing authorisation from the MHRA, though the MHRA has betrayed its trust by allowing misleading labelling of herbal medicines without requiring any evidence whatsoever that they work, see, for example
Why degrees in Chinese medicine are a danger to patients
More quackedemia. Dangerous Chinese medicine taught at Middlesex University
Why does the MHRA refuse to label herbal products honestly? Kent Woods and Richard Woodfield tell me
In contrast to the large reduction in the number of BSc and MSc degrees, there has actually been an increase in two year foundation degrees and HND courses in complementary medicine, at places right near the bottom of the academic heap. The subject is sinking to the bottom. With luck it will vanish entirely from universities before too long.
Although all of the degrees in magic medicine are from post-1992 universities, the subject has crept into more prestigious universities. Of these, the University of Southampton is perhaps the worst, because of the presence of George Lewith, and his defender, Stephen Holgate. Others have staunch defenders of quackery, including the University of Warwick, University of Edinburgh and St Batholomew’s.
Why have all these courses closed?
One reason is certainly the embarrassment caused by exposure of what’s taught on the courses. Professors Petts (Westminster) and Driscoll (Middlesex) must be aware that googling their names produces references to this and other skeptical blogs on the front page. Thanks to some plain brown emails, and, after a three year battle, the Freedom of Information Act, it has been possible to show here the nonsense that has been foisted on students by some universities. Not only is this a burden on the taxpayer, but, more importantly, some of it is a danger to patients.
When a course closes, it is often said that it is because of falling student numbers (though UCLAN and Salford did not use that excuse). Insofar as that is true, the credit must go to the whole of the skeptical movement that has grown so remarkably in the last few years. Ben Goldacre’s "ragged band of bloggers" have produced a real change in universities and in society as a whole.
The people who should have done the job have either been passive or an active hindrance. The list is long. Vice-chancellors and Universities UK (UUK), the Quality Assurance Agency (QAA), the Hiigher Education Funding Council England (HEFCE), Skills for Health, the Medicines and Health Regulatory Authority ( MHRA) , the Health Professions Council (HPC), the Department of Health, the Prince of Wales and his reincarnated propaganda organisation, the "College of Medicine", the King’s Fund, the Universities and Colleges Union (UCU), OfQual, Edexcel, National Occupational Standards and Qualifications and the Curriculum Authority (QCA).
Whatever happened to that "bonfire of the quangos"?
2 January 2012 The McTimoney College of Chiropractic (owned by BPP University) claims that its “validation” by the University of Wales will continue until 2017. This contradicts the statement from UoW. Watch this space.
3 January 2012. Thanks to Neil O’Connell for drawing my attention to a paper in Pain. The paper is particularly interesting because it comes from the Southampton group which has previously been sympathetic to acupuncture. Its authors include George Lewith. It shows, yet again that there is no detectable difference between real and sham acupuncture treatment. It also shows that the empathy of the practitioner has little effect: in fact the stern authoritarian practitioner may have been more effective.
Patients receiving acupuncture demonstrated clinically important improvements from baseline (i.e., a 29.5% reduction in pain), but despite this, acupuncture has no specific efficacy over placebo for this group of patients. The clinical effect of acupuncture treatment and associated controls is not related to the use of an acupuncture needle, nor mediated by empathy, but is practitioner related and may be linked to the perceived authority of the practitioner.”
Sadly. the trial didn’t include a no-treatment group, so it is impossible to say how much of the improvement is regression to the mean and how much is a placebo effect. The authors admit that it could be mostly the former.
Surely now the misplaced confidence in acupuncture shown by some medical and university people must be in tatters.
In yet another sign that even acupuncture advovates are beginning to notice that it doesn’t work, a recent article Paradoxes in Acupuncture Research: Strategies for Moving Forward, shows some fascinating squirming.
3 January 2012. It is a great pity that some physiotherapists seem to have fallen hook, line and sinker for the myths of acupuncture. Physiotherapists are, by and large, the respectable face of manipulative therapy. Their evidence base is certainly not all one would wish, but at least they are free of the outrageous mumbo humbo of chiropractors. Well, most of them are, but not the Acupuncture Association of Chartered Physiotherapists (AACP), or, still worse, The Association of Chartered Physiotherapists in Energy Medicine, a group that is truly away with the fairies. These organisations are bringing a very respectable job into disrepute. And the Health Professions Council, which is meant to be their regulator, has, like most regulators, done nothing whatsoever to stop it.
5 January 2012. Times Higher Education gives a history of the demise of the University of Wales, Boom or Bust. It’s a useful timeline, but like so many journalists, it’s unwilling to admit that bloggers were on to the problem long before the BBC, never mind the QAA.
There was also a leader on the same topic, Perils of the export business. It again fails to take the QAA to task for its failures.
17 January 2012 Another question answered. I just learned that the ludicrous course in Nutritional Therapy, previously validated by the University of Wales (and a contributor to its downfall), is now being validated by, yes, you guessed, Middlesex University. Professor Driscoll seems determined to lead his univerity to the bottom of the academic heap. His new partnership with the Northern college of Acupuncture is just one of a long list of validations that almost rivals that of the late University of Wales. The course has, of course, an enthusiastic testimonial, from a student. It starts
I work full time as a team leader for a pension company but I am also a kinesiologist and work in my spare time doing kinesiology, reiki and Indian head massage.
Evidently she’s a believer in the barmiest and totally disproved forms of magic medicine. And Middlesex University will give her a Master of Science degree. I have to say I find it worrying that she’s a team leader for a pension company. Does she also believe in the value of worthless derivatives. I wonder?
18 January 2012. the story has gone international, with an interview that I did for Deutsche Welle, UK universities drop alternative medicine degree programs. I’m quoted as saying “They’re dishonest, they teach things that aren’t true, and things that are dangerous to patients in some cases”. That seems fair enough.
There is also an interesting item from July 2010 about pressure to drop payment for homeopathy by German health insurance
31 January 2012
The Daily Telegraph carried a prominent 1200 word account (the title wasn’t mine). The published version was edited slightly.
Almost all the revelations about what’s taught on university courses in alternative medicine have come from post-1992 universities. (For readers not in the UK, post-1992 universities are the many new univerities created in 1992, from former polytechnics etc, and Russell group universities are the "top 20" research-intensive universities)
It is true that all the undergraduate courses are in post-1992 universities, but the advance of quackademia is by no means limited to them. The teaching at St Bartholomew’s Hospital Medical School, one of the oldest, was pretty disgraceful for example, though after protests from their own students, and from me, it is now better, I believe.
Quackery creeps into all universities to varying extents. The good ones (like Southampton) don’t run "BSc" degrees, but it still infiltrates through two main sources,
The first is via their HR departments, which are run by people who tend to be (I quote) "credulous and moronic" when it comes to science.
The other main source is in teaching to medical students. The General Medical Council says that medical students must know something about alterantive medicine and that’s quite right, A lot of their patients will use it. The problem is that the guidance is shockingly vague .
“They must be aware that many patients are interested in and choose to use a range of alternative and complementary therapies. Graduates must be aware of the existence and range of such therapies, why some patients use them, and how these might affect other types of treatment that patients are receiving.” (from Tomorrow’s Doctors, GMC)
In many medical schools, the information that medical students get is quite accurate. At UCL and at King’s (London) I have done some of the familiarisation myself. In other good medical schools, the students get some shocking stuff. St Bartholomew’s Hospital medical School was one example. Edinburgh University was another.
But there is one Russell group university where alternative myths are propagated more than any other that I know about. That is the University of Southampton.
In general, Southampton is a good place, I worked there for three years myself (1972 – 1975). The very first noise spectra I measured were calculated on a PDP computer in their excellent Institute of Sound and Vibration Research, before I wrote my own programs to do it.
But Southanpton also has a The Complementary and Integrated Medicine Research Unit . Oddly the unit’s web site, http://www.cam-research-group.co.uk, is not a university address, and a search of the university’s web site for “Complementary and Integrated Medicine Research Unit” produces no result. Nevertheless the unit is “within the School of Medicine at the University of Southampton”
Notice the usual euphemisms ‘complementary’ and ‘integrated’ in the title: the word ‘alternative’ is never used. This sort of word play is part of the bait and switch approach of alternative medicine.
Teaching about alternative medicine to Southampton medical students.
The whole medical class seems to get quite a lot compared with other places I know about. That’s 250 students (210 on the 5-year course plus another 40 from the 4-year graduate-entry route).
Year 1: Lecture by David Owen on ‘holism’ within the Foundation Course given to all 210 medical students doing the standard (5-year) course.
Year 2: Lecture by Lewith (on complementary medicine, focusing on acupuncture for pain) given within the nervous systems course to the whole medical student year-group (210 students).
Year 3 SBOM (scientific basis of medicine) symposium: The 3-hour session (“Complementary or Alternative Medicine: You Decide”). I’m told that attendance at this symposium is often pretty low, but many do turn up and all of them are officially ‘expected’ to attend.
There is also an optional CAM special study module chosen by 20 students in year 3, but also a small number of medical students (perhaps 2 – 3 each year?) choose to do a BMedSci research project supervised by the CAM research group and involving 16-18 weeks of study from October to May in Year 4. The CAM research group also supervise postgraduate students doing PhD research.
As always, a list of lectures doesn’t tell you much. What we need to know is what’s taught to the students and something about the people who teach it. The other interesting question is how it comes about that alternative medicine has been allowed to become so prominent in a Russell group university. It must have support from on high. In this case it isn’t hard to find out where it comes from. Here are some details.
Year 1 Dr David Owen
David Owen is not part of Lewith’s group, but a member of the Division of Medical Education headed by Dr Faith Hill (of whom, more below). He’s one of the many part-time academics in this area, being also a founder of The Natural Practice .
Owen is an advocate of homeopathy (a past president of the Faculty of Homeopathy). Homeopathy is, of course, the most barmy and discredited of all the popular sorts of alternative medicine. Among those who have discredited it is the head of the alt med unit, George Lewith himself (though oddly he still prescribes it).
And he’s also a member of the British Society of Environmental Medicine (BSEM). That sounds like a very respectable title, but don’t be deceived. It is an organisation that promotes all sorts of seriously fringe ideas. All you have to do is notice that the star speaker at their 2011 conference was none other than used-to-be a doctor, Andrew Wakefield, a man who has been responsible for the death of children from measles by causing an unfounded scare about vaccination on the basis of data that turned out to have been falsified. There is still a letter of support for Wakefield on the BSEM web site.
The BSEM specialises in exaggerated claims about ‘environmental toxins’ and uses phony allergy tests like kinesiology and the Vega test that misdiagnose allergies, but provide en excuse to prescribe expensive but unproven nutritional supplements, or expensive psychobabble like "neuro-linguistic programming".
If it is wrong to expose medical students to someone who believes that dose-response curves have a negative slope (the smaller the dose the bigger the effect -I know, it’s crazy), then it is downright wicked to expose students to a supporter of Andrew Wakefield.
David Owen’s appearance on Radio Oxford, with the indomitable Andy Lewis appears on his Quackometer blog.
Year 2 Dr George Lewith
Lewith is a mystery wrapped in an enigma. He’s participated in some research that is quite good by the (generally pathetic) standards of the world of alternative medicine.
In 2001 he showed that the Vega test did not work as a method of allergy diagnosis. "Conclusion Electrodermal testing cannot be used to diagnose environmental allergies", published in the BMJ .[download reprint].
In 2003 he published "A randomized, double-blind, placebo-controlled proving trial of Belladonna 30C” [download reprint] that showed homeopathic pills with no active ingredients had no effects: The conclusion was "”Ultramolecular homeopathy has no observable clinical effects" (the word ultramolecular, in this context, means that the belladonna pills contained no belladonna).
In 2010 he again concluded that homeopathic pills were no more than placebos, as described in Despite the spin, Lewith’s paper surely signals the end of homeopathy (again). [download reprint]
What i cannot understand is that, despite his own findings, his private practice continues to prescribe the Vega machine and continues to prescribe homeopathic pills. And he continues to preach this subject to unfortunate medical students.
Lewith is also one of the practitioners recommended by BSEM. He’s a director of the "College of Medicine". And he’s also an advisor to a charity called Yes To Life. (see A thoroughly dangerous charity: YesToLife promotes nonsense cancer treatments).
3rd year Student Selected Unit
The teaching team includes:
- David Owen – Principal Clinical Teaching Fellow SoM, Holistic Physician
- George Lewith – Professor of Health Research and Consultant Physician
- Caroline Eyles – Homeopathic Physician
- Susan Woodhead – Acupuncturist
- Elaine Cooke – Chiropractic Practitioner
- Phine Dahle – Psychotherapist
- Keith Carr – Reiki Master
- Christine Rose – Homeopath and GP
- David Nicolson – Nutritionalist
- Shelley Baker – Aromatherapist
- Cheryl Dunford – Hypnotherapist
- Dedj Leibbrandt – Herbalist
More details of the teaching team here. There is not a single sceptic among them, so the students don’t get a debate, just propaganda.
Let’s look at some examples
Chiropractic makes an interesting case, because, in the wake of the Singh-BCA libel case, the claims of chiropractors have been scrutinised as never before and most of their claims have turned out to be bogus. There is a close relationship between Lewith’s unit and the Anglo-European Chiropractic College (the 3rd year module includes a visit there). In fact the handout provided for students, Evidence for Chiropractic Care , was written by the College. It’s interesting because it provides no real evidence whatsoever for the effectiveness of chiropractic care. It’s fairly honest in stating that the view at present is that, for low back pain, it isn’t possible to detect any difference between the usefulness of manipulation by a physiotherapist, by an osteopath or by a chiropractor. Of course it does not draw the obvious conclusion that this makes chiropractic and osteopathy entirely redundant -you can get the same result without all the absurd mumbo jumbo that chiropractors and osteopaths love, or their high-pressure salesmanship and superfluous X-rays. Neither does it mention the sad, but entirely possible, outcome that none of the manipulations are effective for low back pain. There is, for example, no mention of the fascinating paper by Artus et al [download reprint]. This paper concludes
"symptoms seem to improve in a similar pattern in clinical trials following a wide
variety of active as well as inactive treatments."
This paper was brought to my attention through the blog run by the exellent physiotherapist, Neil O’Connell. He comments
“If this finding is supported by future studies it might suggest that we can’t even claim victory through the non-specific effects of our interventions such as care, attention and placebo. People enrolled in trials for back pain may improve whatever you do. This is probably explained by the fact that patients enrol in a trial when their pain is at its worst which raises the murky spectre of regression to the mean and the beautiful phenomenon of natural recovery.”
This sort of critical thinking is conspicuously absent from this (and all the other) Southampton handouts. The handout is a superb example of bait and switch: No nonsense about infant colic, innate energy or imaginary subluxations appears in it.
Acupuncture is another interesting case because there is quite a lot of research evidence, in stark contrast to the rest of traditional Chinese medicine, for which there is very little research.
There is a powerpoint show by Susan Woodhead (though it is labelled British Acupuncture Council).
The message is simple and totally uncritical. It works.
In fact there is now a broad consensus about acupuncture.
(1) Real acupuncture and sham acupuncture have been found to be indistinguishable in many trials. This is the case regardless of whether the sham is a retractable needle (or even a toothpick) in the "right" places, or whether it is real needles inserted in the "wrong" places. The latter finding shows clearly that all that stuff about meridians and flow of Qi is sheer hocus pocus. It dates from a pre-scientific age and it was wrong.
(2) A non-blind comparison of acupuncture versus no acupuncture shows an advantage for acupuncture. But the advantage is usually too small to be of any clinical significance. In all probability it is a placebo effect -it’s hard to imagine a more theatrical event than having someone in a white coat stick long needles into you, like a voodoo doll. Sadly, the placebo effect isn’t big enough to be of much use.
Needless to say, none of this is conveyed to the medical students of Southampton. Instead they are shown crude ancient ideas that date from long before anything was known about physiology as though they were actually true. These folks truly live in some alternative universe. Here are some samples from the acupuncture powerpoint show by Susan Woodhead.
Well this is certainly a "different diagnostic language", but no attempt is made to say which one is right. In the mind of the acupuncurist it seems both are true. It is a characteristic of alternative medicine advocates that they have no difficulty in believing simultaneously several mutually contradictory propositions.
As a final exmple of barminess, just look at the acupuncture points (allegedly) on the ear The fact that it is a favoured by some people in the Pentagon as battlefield acupuncture, is more reminiscent of the mad general, Jack D. Ripper, in Dr Strangelove than it is of science.
There is an equally uncritical handout on acupuncture by Val Hopwood. It’s dated March 2003, a time before some of the most valuable experiments were done.
The handout says "sham acupuncture
is generally less effective than true acupuncture", precisely the opposite of what’s known now. And there are some bits that give you a good laugh, always helpful in teaching. I like
“There is little doubt that an intact functioning nervous system is required for acupuncture to produce
analgesia or, for that matter, any physiological changes”
Modern techniques: These include hybrid techniques such as electro-acupuncture . . . and Ryadoraku [sic] therapy and Vega testing.
Vega testing!! That’s been disproved dozens of times (not least by George Lewith). And actually the other made-up nonsense is spelled Ryodoraku.
It’s true that there is a short paragraph at the end of the handout headed "Scientific evaluation of acupuncture" but it doesn’t cite a single reference and reads more like excuses for why acupuncture so often fails when it’s tested properly.
Homeopathy. Finally a bit about that most boring of topics, the laughable medicine that contains no medicine, homeopathy. Caroline Eyles is a member for the Society of Homeopaths, the organisation that did nothing when its members were caught out in the murderous practice of recommending homeopathy for prevention of malaria. The Society of Homeopaths also endorses Jeremy Sherr, a man so crazy that he believes he can cure AIDS and malaria with sugar pills.
The homeopathy handout given to the students has 367 references, but somehow manages to omit the references to their own boss’s work showing that the pills are placebos. The handout has all the sciencey-sounding words, abused by people who don’t understand them.
"The remedy will be particularly effective if matched to the specific/particular characteristics of the individual (the ‘totality’ of the patient) on all levels, including the emotional and mental levels, as well as just the physical symptoms. ‘Resonance’ with the remedy’s curative power will then be at it’s [sic] best."
The handout is totally misleading about the current state of research. It says
"increasing clinical research confirms it’s [sic] clinical effectiveness in treating patients, including babies and animals (where a placebo effect would be hard to justify)."
The powerpont show by Caroline Eyles shows all the insight of a mediaeval vitalist
Anyone who has to rely on the utterly discredited Jacques Benveniste as evidence is clearly clutching at straws. What’s more interesting about this slide the admission that "reproducibility is a problem -oops, an issue" and that RCTs (done largely by homeopaths of course) have "various methodological flaws and poor external validity". You’d think that if that was the best that could be produced after 200 yours, they’d shut up shop and get another job. But, like aging vicars who long since stopped believing in god, but are damned if they’ll give up the nice country rectory, they struggle on, sounding increasingly desperate.
How have topics like this become so embedded in a medical course at a Russell group university?
The details above are a bit tedious and repetitive. It’s already established that hardly any alternative medicine works. Don’t take my word for it. Check the web site of the US National Center for Complementary and Alternative Medicine (NCCAM) who, at a cost of over $2 billion have produced nothing useful.
A rather more interesting question is how a good university like Southampton comes to be exposing its medical students to teaching like this. There must be some powerful allies higher up in the university. In this case it’s pretty obvious who thay are.
Professor Stephen Holgate MD DSc CSc FRCP FRCPath FIBiol FBMS FMed Sci CBE has to be the primary suspect, He’s listed as one of Southampton’s Outstanding Academics. His work is nothing to do with alternative medicine but he’s been a long term supporter of the late unlamented Prince of Wales’ Foundation, and he’s now on the advisory board of it’s successor, the so called "College of Medicine" (for more information about that place see the new “College of Medicine” arising from the ashes of the Prince’s Foundation for Integrated Health, and also Don’t be deceived. The new “College of Medicine” is a fraud and delusion ). His description on that site reads thus.
"Stephen Holgate is MRC Clinical Professor of Immunopharmacology at the University of Southampton School of Medicine and Honorary Consultant Physician at Southampton University Hospital Trust. He is also chair of the MRC’s Populations and Systems Medicine Board. Specialising in respiratory medicine, he is the author of over 800 peer-reviewed papers and contributions to scientific journals and editor of major textbooks on asthma and rhinitis. He is Co-Editor of Clinical and Experimental Allergy, Associate Editor of Clinical Science and on the editorial board of 25 other scientific journals."
Clearly a busy man. Personally I’m deeply suspicious of anyone who claims to be the author of over 800 papers. He graduated in medicine in 1971, so that is an average of over 20 papers a year since then, one every two or three weeks. I’d have trouble reading that many, never mind writing them.
Holgate’s long-standing interest in alternative medicine is baffling. He’s published on the topic with George Lewith, who, incidentally, is one of the directors of the "College of Medicine"..
It may be unkind to mention that, for many years now, I’ve been hearing rumours that Holgate is suffering from an unusually bad case of Knight starvation.
The Division of Medical Education appears to be the other big source of support for. anti-scientific medicine. That is very odd, I know, but it was also the medical education people who were responsible for mis-educating medical students at. St. Bartholomew’s and at Edinburgh university. Southampton’s Division of Medical Education has a mind-boggling 60 academic and support staff. Two of them are of particular interest here.
Faith Hill is director of the division. Her profile doesn’t say anything about alternative medicine, but her interest is clear from a 2003 paper, Complementary and alternative medicine: the next generation of health promotion?. The research consisted of reporting anecdotes from interviews of 52 unnamed people (this sort of thing seems to pass for research in the social sciences). It starts badly by misrepresenting the conclusions of the House of Lords report (2000) on CAM. Although it comes to no useful conclusions, it certainly shows a high tolerance of nonsensical treatments.
Chris Stephens is Associate Dean of Medical Education & Student Experience. His sympathy is shown by a paper he wrote In 2001, with David Owen (the homeopath, above) and George Lewith: Can doctors respond to patients’ increasing interest in complementary and alternative medicine?. Two of the conclusions of this paper were as follows.
"Doctors are training in complementary and alternative medicine and report benefits both for their patients and themselves"
Well, no actually. It wasn’t true then, and it’s probably even less true now. There’s now a lot more evidence and most of it shows alternative medicine doesn’t work.
"Doctors need to address training in and practice of complementary and alternative medicine within their own organisations"
Yes they certainly need to do that.
And the first thing that Drs Hill and Stephens should do is look a bit more closely about what’s taught in their own university, I hope that this post helps them,
4 July 2011. A correspondent has just pointed out that Chris Stephens is a member of the General Chiropractic Council. The GCC is a truly pathetic pseudo-regulator. In the wake of the Simon Singh affair it has been kept busy fending off well-justified complaints against untrue claims made by chiropractors. The GCC is a sad joke, but it’s even sadder to see a Dean of Medical Education at the University of Southampton being involved with an organisation that has treated little matters of truth with such disdain.
A rather unkind tweet from (ex)-chiropractor @RichardLanigan.
“Chris is just another light weight academic who likes being on committees. Regulatory bodies are full of them”
The mainstream media eventually catch up with bloggers. BBC1 TV (Wales) produced an excellent TV programme that exposed the enormous degree validation scam run by the University of Wales. It also exposed the uselessness of the Quality Assurance Agency (QAA). Both these things have been written about repeatedly here for some years. It was good to see them getting wider publicity.
Watch the video of the programme (Part 1, and Part 2) "Week In Week Out – University Challenged." “The programme examines how pop stars and evangelical Christians are running colleges offering courses validated by the University of Wales.” (I make a brief appearance, talking about validation of degrees in Chinese Medicine).
In October 2008 I posted Another worthless validation: the University of Wales and nutritional therapy. With the help of the Freedom of Information Act, it was possible to reveal the mind-boggling incompetence of the validation process used by the University of Wales.
McTimoney College of Chiropractic
The Chiropractic “degrees” from the McTimoney College of Chiropractic are also validated by the University of Wales by an equally incompetent, or perhaps I should say bogus, procedure. More details can be found at The McTimoney Chiropractic Association would seem to believe that chiropractic is “bogus”, and in a later post, Not much Freedom of Information at University of Wales, University of Kingston, Robert Gordon University or Napier University.
Andy Lewis has also written about chiropractic in The University of Wales is Responsible for Enabling Bogus* Chiropractic Claims to be Made.
Sadly the BBC programme did not have much to say about these domestic courses, but otherwise it was excoriating. In particular it had extensive interviews with Nigel Palastanga, whose astonishing admission that courses were validated withour seeing what was taught on them was revealed here two years ago. After that revelation, the vice-chancellor of UoW, Marc Clement BSc PhD CEng CPhys FIET FInstP, promoted Palastanga to be pro-vice-chancellor in charge of Learning, Teaching and Enhancement (I know, you couldn’t make it up).
In the documentary Palastanga said
"It’s a major business. We earn a considerable amount of money."
That was obvious two years ago, but it’s good to hear it from the horse’s mouth.
After a section that revealed a bit about what goes on at two very fundamentalist bible colleges which gave University of Wales degrees, A. C. Grayling commented thus.
"They are there to train advocates for the biblical message and that is absolutely not, by a very very long chalk, what a university should be doing.. . . A respectable British Higher education institution like the University of Wales shouldn’t be touching them with a bargepole."
Undaunted, Palastanga responded
“That’s his opinion. I would say they are validated to the highest standards. They match what are called QAA benchmark. We have serious academics looking at them, and their academic standards are established at the very highest level.”
And if you believe that, you will truly believe anything.
You can download here one of many moderator’s reports obtained under the Freedom of Information Act. This one is for the BSc (Hons) Chiropractic. It is entirely typical of theuncritical boxticking approach to validation, Nowhere does it say "subluxation is nonsense", though even the GCC now admit that.
Traditional Chinese Medicine
The University of Wales validates several courses in what almost everyone but them classifies as quackery. As well as chiropractic and “nutritional therapy”, there is herbalism. For example a course at a college in Barcelona issues University of Wales degrees in Traditional Chinese medicine, a subject that is a menace to public health.. I was asked to comment on the course, and on a bag of herbs that the presenter had been sold to treat depression.
Radix Bupleuri Chinensis
Radix Angelicae Sinensis
Radix Paeoniae Lactiflorae
Rhizoma Atractylodis Macrocephalae
Sclerotium Poriae Cocos
Radix Glycyrrhizae Uralensis
Cortex Moutan Radicis (Paeonia Suffruticosa)
Fructus Gardeniae Jasminoidis
Herba Menthae Haplocalycis
Zingiber officinale rhizome-fresh
Ingredients of a custom mixture.
There is no good evidence that any of the ingredients help depression, in fact next to nothing is known about most of them, apart from liquorice and ginger. Swallowing them would be rather reckless. They fall right into the description of any herbal medicine, in the Patients’ Guide, "Herbal medicine: giving patients an unknown dose of an ill-defined drug, of unknown effectiveness and unknown safety. "
Of the degrees, I said
"There’s no evidence that it [the herbs] does you any good. It may be dangerous because you have no idea of the dose. Degrees in Chinese Medicine consist of three years spent memorising myths and pre-scientific, er, untruths. That isn’t a degree, it’s a travesty."
"We’ve had long debates in the Health Committee about where we would draw the line about what we validate. They have to demonstrate to us that there is some scientific basis for the practice, that there is an established curriculum, that there is an established safe practice."
The presenter asked him "So you are confident that Chinese medicine works? Palastanga replied
" I didn’t say that. I said that there is evidence that it does work . . We are trying to enforce these professions to undertake effective research."
That statement is simply not true, as shown by the response of the validation committee to the application for validation of the course in “Nutritional Therapy” at the Northern College of Acupuncture, documented previously. The fact of the matter is that the validation proceeded without looking at what was actually taught, and without even a detailed timetable of lectures. The committee looked only at the official documents presented to it and was totally negligent in failing to discover some of the bizarre beliefs of the people who were giving the course.
Palastanga went on to raise the usual straw man argument, about how little regular medicine is based on good evidence (though admittedly that is certainly true in his own field -he is a physiotherapist).
Fazley International College Kuala Lumpur
This business college in Kuala Lumpur offered University of Wales degrees. Its 32-year old president is a part time pop star with impressive looking qualifications
The presenter pointed out that
" His doctorate and his MBA were awarded in that citadel of education, Cambridge. Here he is, pictured at the city’s prestigious business school. He was there for all of four days and walked away with a doctorate. But the degree was not from the University of Cambridge, but from the now defunct "European Business School Cambridge". It never had the right to award degrees."
Neither the University of Wales nor the QAA had noticed this unfortunate fact. Once the TV team had done their job for them, the UoW withdrew support. though, as of 15 November 2010, that is not obvious from Fazley’s web site.
Mr (not Dr) Fazley seemed rather pleased about how students were attracted by the connection with the Prince of Wales. The fact that he is Chancellor of the University of Wales seems not inappropriate, given the amount of quackery they promote.
Quality Assurance Agency (QAA)
“Why don’t regulators prevent BSc degrees in anti-science? The Quality Assurance Agency for Higher Education (QAA) claims that “We safeguard and help to improve the academic standards and quality of higher education in the UK.” It costs taxpayers £11.5 million (US$22 million) annually. It is, of course, not unreasonable that governments should ask whether universities are doing a good job. But why has the QAA not noticed that some universities are awarding BSc degrees in subjects that are not, actually, science? The QAA report on the University of Westminster courses awards a perfect score for ‘curriculum design, content and organization,’ despite this content consisting largely of what I consider to be early-nineteenth-century myths, not science. It happens because the QAA judges courses only against the aims set by those who run the QAA, and if their aims are to propagate magic as science, that’s fine.”
That was illustrated perfectly in the documentary when Dr Stephen Jackson of the QAA appeared to try to justify the fact that the QAA had, like the University of Wales, failed entirely to spot any of the obvious problems. He had a nice dark suit, tie and poppy, but couldn’t disguise the fact that the QAA had given high ratings to some very dubious courses.
The QAA sent nine people to the other side of the globe, at a cost of £91,000. They could have done a lot better if they’d spent 10 minutes with Google at home.
Universities UK (UUK)
Needless to say, the Committee of Vice-Chancellors and Principals has said nothing at all. As usual, Laurie Taylor had it all worked out in Times Higher Education (4th November).
Speaking to our reporter Keith Ponting (30), he commended UUK’s decision to say absolutely nothing whatsoever about the abolition of all public funding for the arts and humanities.
He also praised UUK’s total silence on Lord Browne’s view that student courses should primarily be evaluated by their employment returns.
When pressed by Ponting for his overall view of UUK’s failure to respond in any way at all to any aspect of the Browne Review, he described it as “welcome evidence, in a world of change, of UUK’s consistent commitment over the years to ineffectual passivity”.
Meanwhile, a University of Wales video on YouTube
A couple of days later, a search of Google news for the “University of Wales” shows plenty of fallout. The vice-chancellor claims that ““The Minister’s attack came as a complete and total surprise to me”. That can’t be true. It is over two years since I told him what was going on, and if he was unaware of it, that is dereliction of duty. It is not the TV programme that brought the University into disrepute, it was the vice-chancellor.
Chiropractors are getting very touchy indeed, all over the world. And no wonder, because their claims are being exposed as baseless as never before, in the wake of their attempts to stifle criticism by legal action..
In March, Shaun Holt appeared on Breakfast TV in New Zealand. Holt has done a lot of good work on TV in debunking some of the preposterous claims made by quacks. See him on YouTube.
This time he talked about chiropractic. Here is the video.
One could argue that he was over generous to chiropractic, especially when talking about their effectiveness in treating low back pain. He said, quite rightly, that chiropractors are no better than physiotherapists at treating low back pain.
But a recent trial suggests that neither are much good. “A randomised controlled trial of spinal manipulative therapy in acute low back pain” (Juni et al., 2009 in the BMJ; see also coverage in Pulse). This trial compared standard care with standard care plus spinal manipulative therapy (SMT). The results were negative, despite the fact that this sort of A + B vs B design is inherently biassed in favour of the treatment (see A trial design that generates only ”positive” results, Ernst & Lee 2008, Postgrad Med J.).
"SMT was performed by a specialist in manual medicine, chiropractice and rheumatology (GH), a specialist in physical medicine (DV) or an osteopath (RvB), all proficient in SMT."
"Conclusions: SMT is unlikely to result in relevant early pain reduction in patients with acute low back pain."
Admittedly, the trial was quite small (104 patients, 52 in each group) so it will need to be confirmed. but the result is entirely in line with what we knew already.
It also adds to the evidence that the recommendation by NICE of SMT by chiropractors constitutes their biggest failure ever to assess evidence properly. If NICE don’t amend this advice soon, they are in danger of damaging their hitherto excellent record.
Despite the moderate tone and accuracy of what Holt said on TV, the New Zealand Chiropractors’ Association made a formal complaint. That is what they like to do, as I learned recently, to my cost. It is so much easier than producing evidence.
Quite absurdly the New Zealand Broadcasting Standards Authority (BSA) has upheld some of the complaints. Their judgement can be read here.
The BSA consists of four people, two lawyers and two journalists. So not a trace of scientific expertise among them. Having people like that judging the claims of chiropractors makes as much sense as having them judged by Mr Justice Eady. They seem to be the sort of people who think that if there is a disagreement, the truth must lie half-way between the opposing views.
One of the BSA members, Tapu Misa, has used her newspaper column to quote approvingly the views of the notorious Dr Mercola web site on flu prevention “Your best defence, it says, is to eat right, get lots of sleep, avoid sugar and stress, load up on garlic, Vitamin D and krill oil”. (Snake oil is said to be good too.) There are some odd attitudes to science in some of her other columns too (e.g. here and here). Not quite the person to be judging the evidence for and against chiropractic, I think.
In fact the TV show in question was more than fair to chiropractors. It adopted the media’s usual interpretation of fair and balanced: equal time for the flat earthers. A Chiropractor was invited to reply to Holt’s piece. Here he is.
The chiropractor, Doug Blackbourn, started very plausibly, though a tendency to omit every third syllable made transcription hard work. He established that if you cut yourself you get better (without any help). He established that nerves run down the spinal cord. So far, so good. But then he quickly moved on to the usual flights of fancy.
"We have two premises. The body heals itself and the nervous system runs the body. Now the nervous system runs the body, travels down through the spinal cord so chiropractic is not based on the belief that, you know, energy flows, it’s based on the fact that your nervous system runs the body and [inaudible] affects the overall health of the body"
This statement is totally vague. It has nothing whatsoever to do with the main question, can chiropractors do anything useful. It is sheer flannel.
We’re seeing people, heck, diabetes. I had a quadriplegic come in one time for adjustment, we’ve got stroke people, we’ve got all sorts of conditions. We’re not treating the condition, We’re allowing, checking the spine to see if there’s any interference there that will slow the body down"
“Interference”? “slowing the body down”? These are utterly meaningless phrases that simply serve to distract from the only question that matters.
"Chiropractice is the most safest [sic] profession to go to to get your spine adjusted"
Hmm I thought it was the only job that uses the word ‘adjustment’.
Worst of all was his response to a question about asthma.
Presenter: "So chiropractors are not out there claiming they will cure asthma for example?". Chiropractor: "No"
This is simply untrue, both in New Zealand and in the UK. For a start, just look at what Blackbourn’s own web site says about asthma.
"The challenge, of course, with allergy and asthma medication is there is no end-point. There is no cure. Asthma and allergies, for the most part, are lifelong conditions requiring lifelong medication. Might there be a better way, an alternative solution?
“Alternative” is the key word. Medical treatment is designed to combat symptoms, and is successful to a certain extent with allergies and asthma. Underlying causes are not addressed, however, and symptoms continue year after year. What else might be done?
Enter chiropractic care. Chiropractic health care, with its unique comprehensive approach, is able to offer positive benefit to a variety of conditions and ailments. In the case of allergies and asthma, these “hypersensitivity conditions” may respond well to therapy designed to normalize the body’s flow of nerve signals. To use a metaphor, chiropractic treatment removes roadblocks to the body’s natural healing abilities. Restoring these imbalances may help reduce such hypersensitivity reactions."
Blackbourn’s web site describes him thus
"As a Doctor of Chiropractic, Dr. Doug Blackbourn . . ."
But the qualifications of “Dr” Blackbourn are B.App.Sc (Chiro) M.N.Z.C.A , the same as those of “Dr” Brian Kelly.
After a performance like this, perhaps someone should submit a complaint to the New Zealand Broadcasting Standards Authority.
After all, I notice that they have dismissed complaints from one chiropractor, Sean Parker, after a TV programme looked at the business practices of his private chiropractic practice, The Spinal Health Foundation. Perhaps the BSA understands business better than it understands science.
Is chiropractic crumbling in New Zealand? The New Zealand College of Chiropractic featured in my editorial in the New Zealand Medical Journal, and in the fallout from that article, It’s principle, “Dr” Brian Kelly (B App Sci (Chiro)) seems to be getting desperate. His college is now canvassing for recruits in Canada. They are promised all the woo.
- Subluxation centered techniques – Gonstead, Toggle Recoil, Thompson, Diversified
- Traditional philosophy featuring vitalism and innate healing – congruent curriculum
Perhaps Canada is a good place to recruit, gven the $500 million class action being brought against chiropractors in Canada, after Sandra Nette became tetraplegic immediately after a chiropractor manipulated her neck, Canadian chiropractors must be looking for somewhere to hide.
Stuff and Nonsense. jdc described this story at the time the complaint was lodged.
Shaun Holt’s own blog follows the action.
New Zealand Doctor covers the story.
Bay of Plenty Times “Bay researcher slams television complaint ruling“
In July 2008 I wrote an editorial in the New Zealand Medical Journal (NZMJ), at the request of its editor.
The title was Dr Who? deception by chiropractors. It was not very flattering and it resulted in a letter from lawyers representing the New Zealand Chiropractic Association. Luckily the editor of the NZMJ, Frank Frizelle, is a man of principle, and the legal action was averted. It also resulted in some interesting discussions with disillusioned chiropractors that confirmed one’s worst fears. Not to mention revealing the internecine warfare between one chiropractor and another.
This all occurred before the British Chiropractic Association sued Simon Singh for defamation. The strength of the reaction to that foolhardy action now has chiropractors wondering if they can survive at all. The baselessness of most of their claims has been exposed as never before. No wonder they are running scared. The whole basis of their business is imploding.
Needless to say chiropractors were very cross indeed. Then in February 2009 I had a polite email from a New Zealand chiropractor, David Owen, asking for help to find one of the references in the editorial. I’d quoted Preston Long as saying
"Long (2004)7 said “the public should be informed that chiropractic manipulation is the number one reason for people suffering stroke under the age of 45.”
And I’d given the reference as
7. Long PH. Stroke and spinal manipulation. J Quality Health Care. 2004;3:8–10
I’d found the quotation, and the reference, in Ernst’s 2005 article, The value of Chiropractic, but at the time I couldn’t find the Journal of Quality Healthcare. I did find the same article on the web. At least the article had the same title, the same author and the same quotation. But after finding, and reading, the article, I neglected to change the reference from J Quality Health Care to http://skepticreport.com/sr/?p=88. I should have done so and for that I apologise.
When I asked Ernst about the Journal of Quality Healthcare, he couldn’t find his copy of the Journal either, but he and his secretary embarked on a hunt for it, and eventually it was found.
It turns out that Journal of Quality Healthcare shut down in 2004, without leaving a trace on the web, or even in the British Library. It was replaced by a different journal, Patient Safety and Quality Healthcare (PSQH) A reprint was obtained from them. It is indeed the same as the web version that I’d read, and it highlighted the quotation in question.
The reprint of the original article, which proved so hard to find, can be downloaded here.
The full quotation is this
"Sixty-two clinical neurologists from across Canada, all certified members of the Royal College of Physicians and Surgeons, issued a warning to the Canadian public, which was reported by Brad Stewart, MD. The warning was entitled Canadian Neurologists Warn Against Neck Manipulation. The final conclusion was that endless non-scientific claims are being made as to the uses of neck manipulation(Stewart, 2003). They need to be stopped. The public should be informed that chiropractic manipulation is the number one reason for people suffering stroke under the age of 45."
I have often condemned the practice of citing papers without reading them (it is, of course, distressingly common), so I feel bad about this, though I had in fact read the paper in question in its web version. I’m writing about it because I feel one should be open about mistakes, even small ones.
I’m also writing about it because one small section of the magic medicine community seems to think they have nailed me because of it. David Owen, the New Zealand chiropractor, wrote to the editor of the NZMJ, thus.
The quote [in question] is the public should be informed that chiropractic manipulation is the number one reason for people suffering stroke under the age of 45.
Long PH. Stroke and Manipulation. J Quality Health Care. 2004:3:8-10
This quote actually comes from the following blog article http://www.skepticreport.com/medicalquackery/strokespinal.htm [DC the URL is now http://skepticreport.com/sr/?p=88]
I have attached all my personal communications with Colquhoun. They demonstrate this is not a citation error. Prof Colquhoun believes the origin of the quote doesn’t matter because Long was quoting from a Canadian Neurologists’ report (this is also incorrect). As you can see he fails to provide any evidence at all to support the existance [sic] of the “J Quality Health Care.”
Colquhoun ‘s belief that my forwarding this complaint is me “resorting to threats” is the final nail in the coffin. If he had any leg to stand on where is the threat?
This may seem pedantic but it surely reflects a serious ethical breach. Is it acceptable to make up a reference to try and slip any unsupported statement into a “scientific” argument and thereby give it some degree of credibility?
Incidentally, at the end of the article, conflicts of interest are listed as none. As Colquhoun is a Professor of Pharmacology and much of his research funding no doubt comes from the pharmaceutical industry how can he have no conflict of interest with therapies that do not advocate the use of drugs and compete directly against the billions spent on pain medications each year?
If I may quote Colquhoun himself in his defence of his article (Journal of the New Zealand Medical Association, 05-September-2008, Vol 121 No 1281) I’ll admit, though, that perhaps ‘intellect’ is not what’s deficient in this case, but rather honesty.
Well, here is a threat: I’m exposed as a shill of Big Pharma. ". . . much of his funding no doubt comes from the pharmaceutical industry". I can’t count how many times this accusation has been thrown at me by advocates of magic medicine. Oddly enough none of them has actually taken the trouble to find out where my research funding has come from. None of them even knows enough about the business to realise the extreme improbability that the Pharmaceutical Industry would be interested in funding basic work on the stochastic properties of single molecules. They fund only clinicians who can help to improve their profits,
“I notice that Professor David Colquhoun has so far not felt it relevant to mention his own competing interests and financial involvements with the pharmaceutical industry “
To which my reply was
” Oh dear, Patrick Holford really should check before saying things like “I notice that Professor David Colquhoun has so far not felt it relevant to mention his own competing interests and financial involvements with the pharmaceutical industry”. Unlike Holford, when I said “no competing interests”, I meant it. My research has never been funded by the drug industry, but always by the Medical Research Council or by the Wellcome Trust. Neither have I accepted hospitality or travel to conferences from them. That is because I would never want to run the risk of judgements being clouded by money. The only time I have ever taken money from industry is in the form of modest fees that I got for giving a series of lectures on the basic mathematical principles of drug-receptor interaction, a few years ago.”
I spend a lot of my spare time, and a bit of my own money, in an attempt to bring some sense into the arguments. The alternative medicine gurus make their livings (in some cases large fortunes) out of their wares.
So who has the vested interest?
Does chiropractic actually cause stroke?
As in the case of drugs and diet, it is remarkably difficult to be sure about causality. A patient suffers a vertebral artery dissection shortly after visiting a chiropractor, but did the neck manipulation cause the stroke? Or did it precipitate the stroke in somebody predisposed to one? Or is the timing just coincidence and the stroke would have happened anyway? There has been a lot of discussion about this and a forthcoming analysis will tackle the problem of causality head-on,
My assessment at the moment, for what it’s worth, is that there are some pretty good reasons to suspect that neck manipulation can be dangerous, but it seems that serious damage is rare.
In a sense, it really doesn’t matter much anyway, because it is now apparent that chiropractic is pretty well discredited without having to resort to arguments about rare (though serious) effects. There is real doubt about whether it is even any good for back pain (see Cochrane review), and good reason to think that the very common claims of chiropractors to be able to cure infant colic, asthma and so on are entirely, ahem, bogus. (See also Steven Novella, ebm-first, and innumerable other recent analyses.)
Chiropractic is entirely discredited, whether or not it may occasionally kill people.
Complaint sent to UCL
I had an enquiry about this problem also from my old friend George Lewith. I told him what had happened. Soon after this, a complaint was sent to Tim Perry and Jason Clarke, UCL’s Director and Deputy Director of Academic Services. The letter came not from Lewith or Owen, but from Lionel Milgom. Milgrom is well known in the magic medicine community for writing papers about how homeopathy can be “explained” by quantum entanglement. Unfortunately for him, his papers have been read by some real physicists and they are no more than rather pretentious metaphors. See, for example, Danny Chrastina’s analysis, and shpalman, here. Not to mention Lewis, AP Gaylard and Orac.
Dear Mr Perry and Mr Clark,
I would like to bring to your attention an editorial (below) that appeared in the most recent issue of the New Zealand Medical Journal. In it, one of your Emeritus Professors, David Colquhoun, is accused of a serious ethical breach, and I quote – “Is it acceptable to make up a reference to try and slip any unsupported statement into a “scientific” argument and thereby give it some degree of credibility?”
Professor Colquhoun is well-known for writing extensively and publicly excoriating many forms of complementary and alternative medicine, particularly with regard to the alleged unscientific nature and unethical behaviour of its practitioners. Professor Colquhoun is also a voluble champion for keeping the libel laws out of science.
While such activities are doubtlessly in accord with the venerable Benthamite liberal traditions of UCL, I am quite certain hypocrisy is not. And though Professor Colquhoun has owned up to his error, as the NZMJ’s editor implies, it leaves a question mark over his credibility. As custodians of the college’s academic quality therefore, you might care to consider the possible damage to UCL’s reputation of perceived professorial cant; emeritus or otherwise.
Dr Lionel R Milgrom
So, as we have seen, the quotation was correct, the reference was correct, and I’d read the article from which it came I made a mistake in citing the original paper rather than the web version of the same paper..
I leave it to the reader to judge whether this constitutes a "serious ethical breach", whether I’d slipped in an "unsupported statement", and whether it constitutes "hypocrisy"
It so happens that no sooner was this posted than there appeared Part 2 of the devastating refutation of Lionel Milgrom’s attempt to defend homeopathy, written by AP Gaylard. Thanks to Mojo (comment #2) for pointing this out.
The King’s Fund recently published Assessing complementary practice Building consensus on appropriate research methods [or download pdf].
It is described as being the “Report of an independent advisory group”. I guess everyone knows by now that an “expert report” can be produced to back any view whatsoever simply by choosing the right “experts”, so the first things one does is to see who wrote it. Here they are.
- Chair: Professor Dame Carol Black
- Harry Cayton, Chief Executive, Council for Healthcare Regulatory Excellence
- Professor Adrian Eddleston, then Vice-Chairman, The King’s Fund
- Professor George Lewith, Professor of Health Research, Complementary and Integrated Medicine Research Unit, University of Southampton
- Professor Stephen Holgate, MRC Clinical Professor of Immunopharmacology, University of Southampton
- Professor Richard Lilford, Head of School of Health and Population Sciences, University of Birmingham
We see at once two of the best known apologists for alternative medicine, George Lewith (who has appeared here more than once) and Stephen Holgate.
Harry Cayton is CEO of Council for Healthcare Regulatory Excellence (CHRE) which must be one of the most useless box-ticking quangos in existence. It was the CHRE that praised the General Chiropractic Council (GCC) for the quality of its work. That is the same GCC that is at present trying to cope with 600 or so complaints about the people it is supposed to regulate (not to mention a vast number of complaints to Trading Standards Offices). The GCC must be the prime example of the folly of giving government endorsement to things that don’t work. But the CHRE were not smart enough to spot that little problem. No doubt Mr Cayton did good work for the Alzheimer’s Society. His advocacy of patient’s choice may have helped me personally. But it isn’t obvious to me that he is the least qualified to express an opinion on research methods in anything whatsoever. According to the Guardian he is “BA in English and linguistics from the University of Ulster; diploma in anthropology from the University of Durham; B Phil in philosophy of education from the University of Newcastle.”
Adrian Eddlestone is a retired Professor of Medicine. He has been in academic administration since 1983. His sympathy for alternative medicine is demonstrated by the fact that he is also Chair of the General Osteopathic Council, yet another “regulator” that has done nothing to protect the public
from false health claims (and which may, soon, find itself in the same sort of trouble as the GCC).
Richard Lilford is the only member of the group who has no bias towards alternative medicine and also the only member with expertise in clinical research methods His credentials look impressive, and his publications show how he is the ideal person for this job. I rather liked also his article Stop meddling and let us get on.. He has written about the harm done by postmodernism and relativism, the fellow-travellers of alternative medicine.
Most damning of all, Lewith, Eddlestone and Holgate (along with Cyril Chantler, chair of the King’s Fund, and homeopaths, spiritual healers and Karol Sikora) are Foundation Fellows of the Prince of Wales Foundation for Magic Medicine, an organisation that is at the forefront of spreading medical misinformation.
I shall refer here to ‘alternative medicine’ rather than ‘complementary medicine’ which is used in the report. It is not right to refer to a treatment as ‘complementary’ until such time as it has been shown to work. The term ‘complementary’ is a euphemism that, like ‘integrative’, is standard among alternative medicine advocates whose greatest wish is to gain respectability.
On page 10 we find a summary of the conclusions.
The report identifies five areas of consensus, which together set a framework for moving forward. These are:
- the primary importance of controlled trials to assess clinical and cost effectiveness.
- the importance of understanding how an intervention works
- the value of placebo or non-specific effects
- the need for investment and collaboration in creating a sound evidence base
- the potential for whole-system evaluation to guide decision-making and subsequent research.
The first recommendation is just great. The rest sound to me like the usual excuses for incorporating ineffective treatments into medical practice. Notice the implicit assumption in the fourth point
that spending money on research will establish “a sound evidence base". There is a precedent, but it is ignored. A huge omission from the report is that it fails to mention anywhere that a lot of research has already been done.
Much research has already been done (and failed)
The report fails to mention at all the single most important fact in this area. The US National Institutes of Health has spent over a billion dollars on research on alternative medicines, over a period
of more than 10 years. It has failed to come up with any effective treatments whatsoever. See, for example Why the National Center for Complementary and Alternative Medicine (NCCAM) Should Be Defunded; Should there be more alternative research?; Integrative baloney @ Yale, and most recently, $2.5B Spent, No Alternative Med Cures found. .
Why did the committee think this irrelevant? I can’t imagine. You guess.
The report says
“This report outlines areas of potential consensus to guide research funders, researchers, commissioners and complementary practitioners in developing and applying a robust evidence base for complementary practice.”
As happens so often, there is implicit in this sentence the assumption that if you spend enough money evidence will emerge. That is precisely contrary to the experence in the USA where spending a billion dollars produced nothing beyond showing that a lot of things we already thought didn’t work were indeed ineffective.
And inevitably, and tragically, NICE’s biggest mistake is invoked.
“It is noteworthy that the evidence is now sufficiently robust for NICE to include acupuncture as a treatment for low back pain.” [p ]
Did the advisory group not read the evidence used (and misinterpeted) by NICE? It seems not. Did the advisory group not read the outcome of NIH-funded studies on acupuncture as summarised by Barker Bausell in his book, Snake Oil Science? Apparently not. It’s hard to know because the report has no references.
George Lewith is quoted [p. 15] as saying “to starve the system of more knowledge means we will continue to make bad decisions”. No doubt he’d like more money for research, but if a billion dollars
in the USA gets no useful result, is Lewith really likely to do better?
The usual weasel words of the alternative medicine industry are there in abundance
“First, complementary practice often encompasses an intervention (physical treatment or manipulation) as well as the context for that intervention. Context in this setting means both the physical setting for the delivery of care and the therapeutic relationship between practitioner and patient.” [p. 12]
Yes, but ALL medicine involves the context of the treatment. This is no different whether the medicine is alternative or real. The context (or placebo) effect comes as an extra bonus with any sort of treatment.
“We need to acknowledge that much of complementary practice seeks to integrate the positive aspects of placebo and that it needs to be viewed as an integral part of the treatment rather than an aspect that should be isolated and discounted.” [p. 13]
This is interesting. It comes very close (here and elsewhere) to admitting that all you get is a placebo effect, and that this doesn’t matter. This contradicts directly the first recommendation of the House of Lords report (2000).. Both the House of Lords report on Complementary and Alternative Medicine, and the Government’s response to it, state clearly
“. . . we recommend that three important questions should be addressed in the following order”. (1) does the treatment offer therapeutic benefits greater than placebo? (2) is the treatment safe? (3) how does it compare, in medical outcome and cost-effectiveness, with other forms of treatment?.
The crunch comes when the report gets to what we should pay for.
“Should we be prepared to pay for the so-called placebo effect?
The view of the advisory group is that it is appropriate to pay for true placebo (rather than regression to the mean or temporal effects).” [p 24]
Perhaps so, but there is very little discussion of the emormous ethical questions:that this opinion raises:
- How much is one allowed to lie to patients in order to elicit a placebo effect?
- Is is OK if the practitioner believes it is a placebo but gives it anyway?
- Is it OK if the pratitioner believes that it is not a placebo when actually it is?
- Is it OK for practitioners to go degrees taught by people who believe that it is not a placebo when actually it is?
The report fails to face frankly these dilemmas. The present rather absurd position in which it is considered unethical for a medical practitioner to give a patient a bottle of pink water, but
perfectly acceptable to refer them to a homeopath. There is no sign either of taking into account the cultural poison that is spread by telling people about yin, yang and meridians and such like preposterous made-up mumbo jumbo. That is part of the cost of endorsing placebos. And just when one thought that believing things because you wished they were true was going out of fashion
Once again we hear a lot about the alleged difficulties posed by research on alternative medicine. These alleged difficulties are, in my view, mostly no more than excuses. There isn’t the slightest
difficulty in testing things like herbal medicine or homeopathy, in a way that preserves all the ‘context’ and the ways of working of homeopaths and herbalists. Anyone who reads the Guardian knows
how to do that.
In the case of acupuncture, great ingenuity has gone into divising controls. The sham and the ‘real’ acupuncture always come out the same. In a non-blind comparison between acupuncture and no acupuncture the latter usually does a bit worse, but the effects are small and transient and entirely compatible with the view that it is a theatrical placebo.
Despite these shortcomings, some of the conclusions [p. 22] are reasonable.
“The public needs more robust evidence to make informed decisions about the use of complementary practice.
Commissioners of public health care need more robust evidence on which to base decisions about expenditure of public money on complementary practice.”
What the report fails to do is to follow this with the obvious conclusion that such evidence is largely missing and that until such time as it is forthcoming there should be no question of the NHS paying for alternative treatments.
Neither should there be any question of giving them official government recognition in the form of ‘statutory regulation’. The folly of doing that is illustrated graphically by the case of chiropractic which is now in deep crisis after inspection of its claims in the wake of the Simon Singh defamation case. Osteopathy will, I expect, suffer the same fate soon.
In the summary on p.12 we see a classical case of the tension
Controlled trials of effectiveness and cost-effectiveness are of primary importance
We recognise that it is the assessment of effectiveness that is of primary importance in reaching a judgement of different practices. Producing robust evidence that something works in practice – that it is effective – should not be held up by the inevitably partial findings and challenged interpretations arising from inquiries into how the intervention works.
The headline sounds impeccable, but directly below it we see a clear statement that we should use treatments before we know whether they work. “Effectiveness”, in the jargon of the alternative medicine business, simply means that uncontrolled trials are good enough. The bit about “how it works” is another very common red herring raised by alternative medicine people. Anyone who knows anything about pharmacology that knowledge about how any drug works is incomplete and often turns out to be wrong. That doesn’t matter a damn if it performs well in good double-blind randomised controlled trials.
One gets the impression that the whole thing would have been a lot worse without the dose of reality injected by Richard Lilford. He is quoted as a saying
“All the problems that you find in complementary medicine you will encounter in some other kind of treatment … when we stop and think about it… how different is it to any branch of health care – the answer to emerge from our debates is that it may only be a matter of degree.” [p. 17]
I take that to mean that alternative medicine poses problems that are no different from other sorts of treatment. They should be subjected to exactly the same criteria. If they fail (as is usually the case) they should be rejected. That is exactly right. The report was intended to produce consensus, but throughout the report, there is a scarcely hidden tension between believers on one side, and Richard Lilford’s impeccable logic on the other.
Who are the King’s Fund?
“The King’s Fund creates and develops ideas that help shape policy, transform services and bring about behaviour change which improve health care.”
It bills this report on its home page as “New research methods needed to build evidence for the effectiveness of popular complementary therapies”. But in fact the report doesn’t really recommend ‘new research methods’ at all, just that the treatments pass the same tests as any other treatment. And note the term ‘build evidence’. It carries the suggestion that the evidence will be positive. Experience in the USA (and to a smaller extent in the UK) suggests that every time some good research is done, the effect is not to ‘build evidence’ but for the evidence to crumble further
If the advice is followed, and the results are largely negative, as has already happened in the USA, the Department of Health would look pretty silly if it had insisted on degrees and on statutory regulation.
The King’s Fund chairman is Sir Cyril Chantler and its Chief Executive is Niall Dickson. It produces reports, some of which are better than this one. I know it’s hard to take seriously an organisation that wants to “share its vision” withyou, but they are trying.
“The King’s Fund was formed in 1897 as an initiative of the then Prince of Wales to allow for the collection and distribution of funds in support of the hospitals of London. Its initial purpose was to raise money for London’s voluntary hospitals,”
It seems to me that the King’s Fund is far too much too influenced by the present Prince of Wales. He is, no doubt, well-meaning but he has become a major source of medical misinformation and his influence in the Department of Health is deeply unconstitutional. I was really surprised to see thet Cyril Chantler spoke at the 2009 conference of the Prince of Wales Foundation for Integrated Health, despite having a preview of the sort of make-believe being propagated by other speakers. His talk there struck me as evading all the essential points. Warm, woolly but in the end, a danger to patients. Not only did he uncritically fall for the spin on the word “integrated”, but he also fell for the idea that “statutory regulation” will safeguard patients.
Revelation of what is actually taught on degrees in these subjects shows very clearly that they endanger the public.
But the official mind doesn’t seem ever to look that far. It is happy ticking boxes and writing vacuous managerialese. It lacks curiosity.
The British Medical Journal published today an editorial which also recommends rebranding of ‘pragmatic’ trials. No surprise there, because the editorial is written by Hugh MacPherson, senior research fellow, David Peters, professor of integrated healthcare and Catherine Zollman, general practitioner. I find it a liitle odd that the BMJ says “Competing Interests: none. David Peters interest is obvious from his job description. It is less obvious that Hugh MacPherson is an acupuncture enthusiast who publishes mostly in alternative medicine journals. He has written a book with the extraordinary title “Acupuncture Research, Strategies for Establishing an Evidence Base”. The title seems to assume that the evidence base will materialise eventually despite a great deal of work that suggests it won’t. Catherine Zollman is a GP who is into homeopathy as well as acupuncture. All three authors were speakers at the Prince of Wales conference, described at Prince of Wales Foundation for magic medicine: spin on the meaning of ‘integrated’.
The comments that follow the editorial start with an excellent contribution from James Matthew May. His distinction between ‘caring’ and ‘curing’ clarifies beautifully the muddled thinking of the editorial.
Then a comment from DC, If your treatments can’t pass the test, the test must be wrong. It concludes
“At some point a stop has to be put to this continual special pleading. The financial crisis (caused by a quite different group of people who were equally prone to wishful thinking) seems quite a good time to start.”
Today, 29 July 2009, a large number of magazines and blogs will publish simultaneously Simon Singh’s article. The Guardian was forced to withdraw it, but what he said must be heard (even if the word ‘bogus’ is now missing).
This is an edited version if the article in the Guardian that resulted in the decision of the British Chiropractic Association to sue Singh for libel. That decision was bad for Singh, though its effects could yet be good for the rest of the world, Firstly the decision to use law rather than rational argument stands a good chance of destroying chiropractic entirely because its claims have now come under scrutiny as never before, and they have been found wanting. Secondly, the support for Singh has been so enormous that there must now be a good chance of getting the UK’s iniquitous laws about defamation changed.
Beware the spinal trap
Some practitioners claim it is a cure-all, but the research suggests chiropractic therapy has mixed results – and can even be lethal, says Simon Singh.
You might be surprised to know that the founder of chiropractic therapy, Daniel David Palmer, wrote that “99% of all diseases are caused by displaced vertebrae”. In the 1860s, Palmer began to develop his theory that the spine was involved in almost every illness because the spinal cord connects the brain to the rest of the body. Therefore any misalignment could cause a problem in distant parts of the body.
In fact, Palmer’s first chiropractic intervention supposedly cured a man who had been profoundly deaf for 17 years. His second treatment was equally strange, because he claimed that he treated a patient with heart trouble by correcting a displaced vertebra.
You might think that modern chiropractors restrict themselves to treating back problems, but in fact some still possess quite wacky ideas. The fundamentalists argue that they can cure anything, including helping treat children with colic, sleeping and feeding problems, frequent ear infections, asthma and prolonged crying – even though there is not a jot of evidence.
I can confidently label these assertions as utter nonsense because I have co-authored a book about alternative medicine with the world’s first professor of complementary medicine, Edzard Ernst. He learned chiropractic techniques himself and used them as a doctor. This is when he began to see the need for some critical evaluation. Among other projects, he examined the evidence from 70 trials exploring the benefits of chiropractic therapy in conditions unrelated to the back. He found no evidence to suggest that chiropractors could treat any such conditions.
But what about chiropractic in the context of treating back problems? Manipulating the spine can cure some problems, but results are mixed. To be fair, conventional approaches, such as physiotherapy, also struggle to treat back problems with any consistency. Nevertheless, conventional therapy is still preferable because of the serious dangers associated with chiropractic.
In 2001, a systematic review of five studies revealed that roughly half of all chiropractic patients experience temporary adverse effects, such as pain, numbness, stiffness, dizziness and headaches. These are relatively minor effects, but the frequency is very high, and this has to be weighed against the limited benefit offered by chiropractors.
More worryingly, the hallmark technique of the chiropractor, known as high-velocity, low-amplitude thrust, carries much more significant risks. This involves pushing joints beyond their natural range of motion by applying a short, sharp force. Although this is a safe procedure for most patients, others can suffer dislocations and fractures.
Worse still, manipulation of the neck can damage the vertebral arteries, which supply blood to the brain. So-called vertebral dissection can ultimately cut off the blood supply, which in turn can lead to a stroke and even death. Because there is usually a delay between the vertebral dissection and the blockage of blood to the brain, the link between chiropractic and strokes went unnoticed for many years. Recently, however, it has been possible to identify cases where spinal manipulation has certainly been the cause of vertebral dissection.
Laurie Mathiason was a 20-year-old Canadian waitress who visited a chiropractor 21 times between 1997 and 1998 to relieve her low-back pain. On her penultimate visit she complained of stiffness in her neck. That evening she began dropping plates at the restaurant, so she returned to the chiropractor. As the chiropractor manipulated her neck, Mathiason began to cry, her eyes started to roll, she foamed at the mouth and her body began to convulse. She was rushed to hospital, slipped into a coma and died three days later. At the inquest, the coroner declared: “Laurie died of a ruptured vertebral artery, which occurred in association with a chiropractic manipulation of the neck.”
This case is not unique. In Canada alone there have been several other women who have died after receiving chiropractic therapy, and Edzard Ernst has identified about 700 cases of serious complications among the medical literature. This should be a major concern for health officials, particularly as under-reporting will mean that the actual number of cases is much higher.
If spinal manipulation were a drug with such serious adverse effects and so little demonstrable benefit, then it would almost certainly have been taken off the market.
Simon Singh is a science writer in London and the co-author, with Edzard Ernst, of Trick or Treatment? Alternative Medicine on Trial. This is an edited version of an article published in The Guardian for which Singh is being personally sued for libel by the British Chiropractic Association.
That’s a great account of the evidence. Notice the conclusion,
“If spinal manipulation were a drug with such serious adverse effects and so little demonstrable benefit, then it would almost certainly have been taken off the market“.
It is the job of NICE to evaluate critically that sort of thing, which makes it all the odder that the NICE guidance group, very unusually, failed to assess properly the evidence for chiropractic.

While we are on the topic of chiropractic, my comment, The hidden cost of endorsing voodoo, appeared at last on the BMJ article about NICE’s low back pain guidance. The thread came back to life after the British Pain Society voted out its president, Paul Watson, a physiotherapist who was a member of the group that wrote the guidance.
Some of the links Links to some of the many repostings of Singh’s article today are aggregated at Sense about Science. There where over 200 in a single day. The British Chiropractic Association tried to suppress criticism, but they clearly don’t understand the web.
“An intrepid, ragged band of bloggers. Chiropractors may regret choosing to sue Simon Singh, springing online scientists into action”. Ben Goldacre has summed up the reaction of the blogosphere with characteristically fine style in the Guardian. Ragged? Moi? The blog version (with links) is here.
On 17th June 2009, 15 months after Singh’s article was published, the British Chiropractic Association (BCA) has finally produced its evidence (though only after enormous pressure from bloggers [download as pdf]..
Jack of Kent has already made some comments from the legal point of view.
As expected, the list of references they give is truly pathetic, The list of 29 references has nine about infantile colic, four about asthma (two of which refer to osteopathy not chiropractic). three about the safety of chiropractic (a contentious matter but not the point here) and three about the safety of non-steroidal anti-inflammatory drugs (an important matter but utterly irrelevant here).
Let’s look at the papers about colic. Most are in obscure alternative medicine journals, not easily available, but the BCA’s own synopsis is sufficient for now.
Klougart N, Nilsson N and Jacobsen J (1989) Infantile Colic Treated by Chiropractors: A Prospective Study of 316 Cases, J Manip Physiol Ther,12:281-288. [ download thr reprint]. As evidence it is about as useless as the infamous Spence study so beloved of homeopaths. There was no control group at all. It simply follows 316 babies and found that most of them eventually got better. Well, they do, don’t they? It is a sign of the pathetic standard of research in chiropractic that anyone should think this paper worth mentioning at all.
Mercer, C. and Nook, B. in the Proceedings of the 5th Biennial Congress of the World Federation of Chiropractic (1999) (so no peer review, for what that is worth). “Resolution of symptoms [of infantile colic] in 93% of infants treated with spinal manipulation”.. This sounds as useless as Klougart et al. Why only 93% one wonders? Every parent knows that 100 percent of babies stop crying eventually.
Wiberg et al. J Manip Physiol Ther, 1999, 242 517 – 522. This one was randomised (but not blind) and showed that spinal manipulation was as effective as dimethicone for colic. [Download pdf]
I expect that all that means is that dimethicone doesn’t work either.
Hayden & Mullinger (2006) Complementary Ther. clin. Prac. “This preliminary study suggested that cranial osteopathic treatment can benefit infants with colic”. So. (a) preliminary and (b) not chiropractic.
Hipperson AJ (2004) Clinical Chiropractic 11, 122 – 129. A report of two case studies, so essentially worthless as evidence The journal isn’t even listed in Pubmed.
Browning M. Miller, J. Clinical Chiropractic (2008) 11, 122—129 [download pdf] Comparison of the short-term effects of chiropractic spinal manipulation and occipito-sacral decompression in the treatment of infant colic: A single-blinded, randomised, comparison trial. This paper just compared two different chiropractic methods. It shows that both are equally effective, or equally plausibly, both are equally ineffective.
- Leach RA (2002) J Manip Physiol Ther, 25, 58 -62. Merely two case reports and they refer to usie of a mechanical device, not the usual chiropractic manipulation.
Miller J (2007) Clinical Chiropractic 10, 139—146 Cry babies: A framework for chiropractic care [download pdf]. No evidence at all here. It isn’t a research paper.
- Nilsson N. 1985 Eur J Chiropr 33, 264 – 255 Infantile colic and chiropractic. “Respondents to a questionnaire revealed that 91% of of infants improved after 2 – 3 manipulations”. Again, no controls. So, babies stop crying, eventually.
That seems to be the best they can do. What they don’t do is mention any of the papers that contradict their claims. They cite Sackett et al. (1996) as their criterion for what constitutes evidence, That paper says “Evidence based medicine is the conscientious, explicit, and judicious use of current best evidence”. That means all the evidence. So why, for example, is there no mention of Olafsdottir et al. (2001), “Randomised controlled trial of infantile colic treated with chiropractic spinal manipulation”. That is one of the few really good papers in the area. It compared chiropractic treatment of babies for colic with placebo treatment (the nurse just held the baby for 10 minutes (the time the chiropractor took). The conclusion was
Conclusion Chiropractic spinal manipulation is no more effective than placebo in the treatment of infantile colic. This study emphasises the need for placebo controlled and blinded studies when investigating alternative methods to treat unpredictable conditions such as infantile colic.
More on this dishonest selectivity can be found at Holfordwatch.
No doubt there will soon be more analyses of what passes, in the eyes of the BCA, for evidence, The nine papers they cite for colic are truly pathetic. Not a single one of them amounts to anything that would be recognised as evidence in the real world. And papers that do provide real evidence are not mentioned.
As always, the blogs provided a very fast response to a document that appeared only late last night. And, as always, these unpaid people, working in their spare time, have done a far better job than the suits at the BCA (or NICE).
Here are some of them.

Laurie Taylor says it all.
Could this bit (dated 18 June) in Laurie Taylor’s saga of the University of Poppleton possibly have been inspired by the Singh affair?
Sweet smell of success
Our campus burst into colour last week as members of the Department of Aromatherapy, led by Professor Gwendolyn Frisson, paraded round the former administrative block happily waving bunches of wild carrot, devil’s claw, cinnamon leaf and lime blossom.
What sparked the herbal celebration was the news of a full retraction from the journalist on the Poppleton Evening News who had described the department in print as “a hotchpotch of untestable propositions and unproven medical interventions”.
The journalist in question, Simeon Rainbow, explained in his published retraction that he’d had time to reflect on the department’s reaction to his original article and now fully recognised that there was no better way of deciding upon the scientific validity of practices such as aromatherapy than by threatening anyone who denied such validity with an enormously costly libel action.
Professor Frisson said that she welcomed the retraction. She would now be able to return with renewed enthusiasm to her research on the beneficial effects of grated angelica root on patients with advanced encephalitis.
A flood of complaints against chiropractors has arrived at the General Chiropractic Council (GCC) in the wake of the British Chiropractic Association (BCA) v Singh affair. It is really rather beautiful that people have put some such enormous effort into writing complaints for no gain to themselves.
My own paltry two complaints to the GCC produced an interesting reaction. Yesterday I was told by the GCC
“Under the provisions of the General Chiropractic Council (Investigating Committee) Rules
2000 (“the Rules”), the Committee is required to invite you to make a statement of evidence in relation to your complaint by way of statutory declaration or affidavit. If you wish to, you can discuss your complaint with a solicitor who acts on behalf of the Committee who could help you draft a statement of evidence that meets the requirements of the Rules. The General Chiropractic Council will pay for the Investigating Committee solicitor’s costs and will reimburse you for any fee you subsequently pay for having your witness statement sworn at a location convenient to you.”
Naturally I shall take up this offer. If the same offer is made to everyone who complained (must be approaching 600), the legal fees incurred by the GCC would presumably be enough to bankrupt them. No wonder they are wriggling.
Here is a letter sent by the GCC’s Chief Executive and Registrar, Margaret Coats, a couple of days ago. It reached me by more than one route, but it is already on the web anyway, on Richard Lanigan’s site, Told you the General Chiropractic Council would find a way to dismiss the complaints. “Protecting the public” my arse! Protecting themselves more like it.. (The GCC has been under attack from within for some time, though mainly because some chiropractors think it regulates too much, not too little)
The bit that is especially interesting is para 2
In quangos like the GCC, complaints don’t necessarily get considered at all. First they go to an investigating committee (IC) which has to decide if there is a ‘case to answer’. Now the GCC wants that criterion to be changed to ‘realistic prospect of success’. Given the GCC’s attitude to evidence it is hard to imagine that any complaint will have a ‘realistic prospect of success’.
The second idea is even more grotesque. The GCC want to be able to dismiss without consideration rafts of complaints where in their opinion, referral to the Professional Conduct Committee (PCC) ‘is not required in the public interest. Or, more likely, not required in the interests of the GCC.
Will the Privy Council acquiesce in this disgraceful attempt to evade complaints? Wel, until January 2008, Graham Donald was a senior civil Servant at the Privy Council bit he now works for the GCC. That must help.
The GCC has been contacted by several Trading Standards Offices too, after complaints made to them about chiropractors. . A response was sent by the GCC on 5 June [download the whole response]. It includes
“It is important to emphasise that the GCC doesn’t claim that chiropractors ‘treat’ asthma, headaches (including migraine) and infant colic. It is possible that chiropractic care may help to alleviate the symptoms of some of these conditions.”
What on earth is that meant to mean?
One hopes that Trading Standards officers are too smart to be taken in by weasel words like that.
The attitude of the GCC to evidence is amply illustrated by the fact that they have said that the rather crude myths known as craniosacral therapy and applied kinesiology fall within their definition of evidence-based care.
Any organisation that can say that is clearly incompetent.
Peter Dixon is a chiropractor. He is chair of the General Chiropractic Council (GCC). He was also a member of the hotly-disputed NICE low back pain guidance group that endorsed (you guessed it) the use of chiropractic, a decision that has led to enormous criticism of the standards of the National Institute of health and Clinical Excellence (NICE).
As a consequence largely of the decision of the British Chiropractic Association (BCA) to sue Simon Singh for defamation, there has been an unprecedented interest taken in the claims made by chiropractors in general.
Peter Dixon has a problem because something like 600 individual complaints about unjustified health claims have been sent to the GCC. Even when a web site does not claim to be able to benefit things like asthma and colic, a phone call may reveal that claims are made in private (one of the many complaints to the GCC concerns such behaviour by two practices belonging to, ahem, Peter Dixon Associates).
The crucial question is, as always, one of evidence. The BCA claim to have a plethora of evidence for their claims, but they have been strangely reluctant to produce it. In fact evidence is cited on the “Your first visit” page on Dixon’s site.
At the bottom we see “How effective is Chiropractic?”.
That sounds very impressive indeed: . ” . . . patients who received chiropractic treatment improved by 70% more than those given hospital out-patient.”
Several things jump out. First, the Oswestry disability index scale runs for 0 to 100, but scores are plotted only from 0 to 35, so the size of the effects are exaggerated. Second, there are no error bars on the points. Third there is essentially no advantage for chiropractic at all when all patients are taken together (top graph). Fourth, and most important, the patients who were followed up for two years (bottom graph) seem to show a slight advantage for chiropractic but on average, the effect is 7 percent (on the 100 point scale, NOT 70 percent as claimed on the web site of Peter Dixon Associates.
What sort of mistake was made?
The abstract of the paper itself says “A benefit of about 7% points on the Oswestry scale was seen at two years.” How did this become “improved by 70% more”?
It could have been simple a typographical error, but that seems unlikely, Who’d boast about a 7% improvement?
Perhaps it is a question of relative versus absolute change. The Figure does not show the actual scores on the 100 point scale, but rather the change in score, relative to a questionnaire given just before starting treatment. If we look at the lower part of the Figure, restricted to those patients who stayed with the trail for 2 years (by this time 28% of the patients had dropped out), we see that there is a reduction in score (improvement) of about 10 points on the 100 point scale with hospital treatment (not a very impressive response). The improvement with those sent to private chiropractic clinics was about seven points bigger. So a change from 10 to 17 is a 70 percent change. What’s wrong with that?
What’s wrong is that it is highly misleading, as relative changes often are. Imagine that the hospital number had been 7 points and the chiropractic number had been 14 (both out of 100). That would mean that both treatments had provided very modest benefits to the patients. Would it then be fair to describe the chiropractic patients as have improved by 100 percent more than the hospital patients, when in fact neither got much benefit? Of course it would not. To present the results in this way would be highly deceptive.
Put another way, a 70% increase in a trivial effect is still pretty trivial.
That isn’t all either. The paper has been analysed in some detail on the ebm-first site. The seven point difference on a 100 point scale, though it may be real, is too small to be ‘clinically significant’ In other words the patient would scarcely notice such a small change. Another problem lies in the nature of the comparison. Patients were, quite properly, allocated at random to chiropractic or to to hospital treatment. BUT the comparion was very from blind. one group was treated in hospital. The other group was sent to private chiropractic clinics. The trivial 7 point difference could easily be as much to do with the thickness of the carpets rather than any effect of spinal manipulation.
What this paper really tells you is that neither treatment is very effective and that there is little to choose between them.
It is really most unfortunate that the chairman of the GCC should show himself to be so careless about evidence at a time when the evidence for the claims of chiropractors is under inspection as never before. It does not add to their case for criticising Simon Singh and it does not add to one’s confidence in the judgement of the NICE guidance group.
The Pain Society revolt. A letter has been sent from several distinguished members of the British Pain Society to its President and Council.
“We, the undersigned, call upon the President of the British Pain Society to issue a statement to NICE and to the press condemning outright the conclusions of the recent UK National Institute for Health and Clinical Excellence (NICE) guidelines . . .”
The sigificance of this letter is that the present president of the British Pain Society is Professor Paul Watson who was a member of the NICE guidance group that produced the recommendations which have engendered such criticism. He was clinical advisor to the guidance group. There is a video of Paul Watson talking about back pain, that seems to me to illustrate very well the problem with the guidance. He says it is a huge problem (everyone knows that) and that something must be done, but he doesn’t say what. There is no admission that, in very many cases, nobody knows what to do. It is exactly this sort of hubris that that makes the NICE report so bad,
One caustic comment on the letter says
“We are led by a physiotherapist! A Professor who cannot even interpret straight forward evidence when it is presented to him on a plate.
Who’s going to be the next BPS President? A Hospital Porter?”
This is another short interruption in the epic self-destruction of chiropractors. In a sense it is more serious. One expects quacks to advocate quackery. What you don’t expect is that the National Institute of Clinical Excellence (NICE) will endorse it. Neither do you expect the Medicines and Healthcare products Regulatory Agency (MHRA) to betray its mandate to make sure that medicines work.
The saga of the NICE low back pain guidance has been the subject of a deluge of criticism, It seems doubtful that the guidance can survive, not least because of its absurd endorsement of chiropractic, at a time when chiropractic is undergoing self-immolation as a consequence of the persecution of Simon Singh by the British Chiropractic Association (see here, and here, and here, and here and thousands of other sites).
The other betrayal has come to the for after the MHRA approved highly misleading labelling of a homeopathic preparation. At the time,
in 2006, when the principle was approved by the MHRA, just about every scientific organisation, even the Royal Society, condemned the action. What was discouraging that the clinical organisations all stayed silent. It is still a mystery why the MHRA made this enormous mistake, Some said that European regulations required it, but that is quite untrue, as Les Rose has shown. It appears to have been the result of a pusillanimous MHRA bowing to pressure from a deeply unscientific Department of Health (a letter from Caroline Flint at the time borders on the surreal).
On 20 May 2009, the British Medical Journal printed an article Drugs agency grants its first licence to homoeopathic product by Deborah Cohen (available free). The comments were mostly highly critical of the MHRA. The BMJ asked, as it does from time to time, for my comment to be converted to a letter
for the print edition. That isn’t freely available, so here it is.
Published 9 June 2009, doi:10.1136/bmj.b2333
Homoeopathic product licence
MHRA label seems to be illegal
The strap line for the Medicines and Healthcare products Regulatory Agency (MHRA) is “We enhance and safeguard the health of the public by ensuring that medicines and medical devices work and are acceptably safe.”
Yet the MHRA has made mockery of its own aims by ignoring the bit about “ensuring that medicines work” and allowing Arnica 30C pills to be labelled: “a homoeopathic medicinal product used within the homoeopathic tradition for the symptomatic relief of sprains, muscular aches, and bruising or swelling after contusions.”1
This label should be illegal anyway because the pills contain no trace of the ingredient on the label, but this deceit has been allowed through a legal loophole for a long time now. If you sold strawberry jam that contained not a trace of strawberry you’d be in trouble.
But I can see no legal loophole that allows the manufacturers of Arnica 30C to evade the provisions of the Consumer Protection from Unfair Trading Regulations 2008. One of the 31 commercial practices which are in all circumstances considered unfair is “falsely claiming that a product is able to cure illnesses, dysfunction, or malformations.”
The consumer protection laws apply to the way that “the average consumer” will interpret the label. The average consumer is unlikely to know that “used within the homoeopathic tradition” is a form of weasel words that actually means “there isn’t a jot of evidence that the medicine works.”
Since there is not the slightest evidence that Arnica 30C pills provide symptomatic relief of sprains, etc, the labelling that the MHRA has approved seems to be illegal. The MHRA is not selling anything itself, so I presume that it won’t find itself in court, but anyone who follows its advice could well do so.

It is, I suppose, just a sign of the chaos that reigns in the multiple agencies and quangos responsible for ‘regulation’ that one arm of government proposes action that a different branch would consider illegal. That is an inevitable consequence of trying to regulate something without first deciding whether it is nonsense or not. The Department of Health appears to be quite incapable of grasping this simple and obvious fact.
Health: best treatments. The Guardian seems to the be picking up BMJ stories and ran this one.
That isn’t my title. It is the title of a post by Richard Lanigan, with whom I’ve been corresponding. He has a major grudge against the General Chiropractic Council. And in particular he is disaffected about the GCC’s chair, Peter Dixon, about whom he has written a lot, I can’t judge the details of his complaints, but they are laid out in detail on his blog, http://chiropracticlive.com/
Particular interest attaches to his recent revelation of a letter that was sent on July 8th to its members by the McTimoney Chiropractic Association. The McTimoney sect of chiropractic are the ‘true believers’ in the most mystical codswallop aspects of the subject. Oddly enough their College has been validated by the University of Wales, I’ve put in a Freedom of Information Act reguest to the University of Wales to see how that happened. Watch this space.
My interpretation of this letter is that it is as near as you can get to an admission, by chiropractors themselves, that many chiropractors make claims that are against the law. And worse still, that the McTimoney Chiropractic Assocation is well aware of that.

Subject: FURTHER URGENT ACTION REQUIRED!
If you are reading this, we assume you have also read the urgent email we sent you last Friday. If you did not read it, READ IT VERY CAREFULLY NOW and – this is most important – ACT ON IT. This is not scaremongering. We judge this to be a real threat to you and your practice.
Because of what we consider to be a witch hunt against chiropractors, we are now issuing the following advice:
The target of the campaigners is now any claims for treatment that cannot be substantiated with chiropractic research. The safest thing for everyone to do is as follows.
When you have done that, please let us know preferably by email or by phone. This will save our valuable time chasing you to see whether it has been done.
CHECK ALL ENTRIES CAREFULLY AND IF IN DOUBT, CONTACT THE RELEVANT PROVIDER TO REMOVE YOUR INFORMATION.
CHECK OUR PREVIOUS EMAILS FOR SPECIFIC ADVICE AND KEY WORDS TO AVOID.
KEEP A LOG OF YOUR ACTIONS.
5. Be wary of ‘mystery shopper’ phone calls and ‘drop ins’ to your practice, especially if they start asking about your care of children, or whiplash, or your evidence base for practice.
IF YOU DO NOT FOLLOW THIS ADVICE, YOU MAY BE AT RISK FROM PROSECUTION.
IF YOU DO NOT FOLLOW THIS ADVICE, THE MCA MAY NOT BE ABLE TO ASSIST YOU WITH ANY PROCEEDINGS.
Although this advice may seem extreme or alarmist, its purpose is to protect you. The campaigners have a target of making a complaint against every chiropractor in the UK who they perceive to be in breach of the GCC’s CoP, the Advertising Standards Code and/or Trading Standards. We have discovered that complaints against more than 500 individual chiropractors have been sent to the GCC in the last 24 hours.
Whatever you do, do not ignore this email and make yourself one of the victims. Some of our members have not followed our earlier advice and now have complaints made against them. We do not want that to happen to you.
Even if you do not have a website, you are still at risk. Our latest information suggests that this group are now going through Yellow Pages entries. Be in no doubt, their intention is to scrutinise every single chiropractor in the UK.
The MCA Executive has worked tirelessly over the last week keeping abreast of development and contacting at risk members. We have decided that this is our best course of action to protect you and the Association at this time of heightened tension. This advice is given to you solely to protect you from what we believe is a concerted campaign, and does not imply any wrongdoing on your part or the part of the Association. We believe that our best course of action is simply to withdraw from the battleground until this latest wave of targeting is over.
Finally, we strongly suggest you do NOT discuss this with others, especially patients, Firstly it would not be ethical to burden patients with this, though if they ask we hope you now have information with which you can respond.
Most importantly, this email and all correspondence from the MCA is confidential advice to MCA members alone, and should not be shared with anyone else.
Please be aware that the office phone lines are likely to be busy, so, if you need our help, please send an email to the office and we will get back to you as soon as we can.

The deleted pages are here. Thanks again to quackometer, here is where you can see the pages that might have been taken down as a result of McTimoney’s letter. I hope they won’t grumble. Really, they sjould never have put them up if they weren’t true, should they?.
The battle for freedom of speech is under way.
|Simon Singh is a great science writer and communicator. He is author of The Big Bang, The Code Book, Fermat’s Last Theorem, and, with Edzard Ernst, Trick or Treatment. They are superb books (buy from Amazon).|
When Singh had the temerity to express an honest opinion, based on the evidence, about that very curious branch of alternative medicine known as chiropractic, the British Chiropractic Association sued Singh for defamation.This was their substitute for producing evidence for their bizarre claims.
Chiropractors seem to be particularly fond of litigation, perhaps because they are so short of evidence. Having had legal threats from them myself, I know how scary it can be, Luckily I was saved by a feisty a journal editor. Singh wasn’t so lucky. The history is recounted here,
The legal aspects of the case are being described by the lawyer who writes under the name of Jack of Kent. He has regular updates on progress.
Put briefly, Libel: A very expensive remedy, to be used only when you have no evidence. Appeals to alternative practitioners because truth is irrelevant
The iniquitous nature of England’s libel law has been described eloquently by Nick Cohen, in the Observer. It is used regularly by rogues and criminals from all over the world to silence their critics. All they need is money. Truth is irrelevant. It is a disgrace to a civilised country.
The cost of defamation cases in the UK is vastly greater than in any other country in Europe:: look at the graph.With enormous courage, Simon Singh has decided to appeal against the ruling by Mr Justice Eady. Scientists and journalists everywhere should rally to support him, if they value the right to express an honest opinion without being bankrupted by a law court. Singh is taking a great risk on behalf of anyone who values freedom of speech.
The charity, Sense abour Science (SaS), has started a campaign to Keep the Libel Laws out of Science.
Read the statement about the campaign on the SaS site, and the current list of signatories. The list of supporters is already very impressive. It includes, for example, professor Lord (Martin) Rees, president of the Royal Society and Astronomer Royal, to Dr Philip Campbell Editor-in-Chief of Nature, David Starkey Historian, Stephen Fry Broadcaster and Author and Baroness Helena Kennedy QC Barrister.
You can sign the statement yourself there. Do it. Now!

In 1894, a local Iowa newspaper, The Davenport Leader, wrote of the founder of chripractic, D.D. Palmer, thus.
“A crank on magnetism has a crazy notion hat he can cure the sick and crippled with his magnetic hands. His victims are the weak-minded, ignorant and superstitious, those foolish people who have been sick for years and have become tired of the regular physician and want health by the short-cut method he has certainly profited by the ignorance of his victim. His increase in business shows what can be done in Davenport, even by a quack.” [quoted in Rose
Shapiro’s book, Suckers]
Today, in the UK, no newspaper would dare to express an opinion like that.
We all hope that Singh will win the appeal. But even if he doesn’t win in the law courts, he will have scored an enormous moral victory. What’s more, chiropractic is now under scrutiny as never before. There is going to be a chiro-fest that will make the British Chiropractic Association rue the day that it decided to use legal bullying in place of reason.
They may even have signed their own death warrant.
