The first post was NICE falls for Bait and Switch by acupuncturists and chiropractors: it has let down the public and itself.

That was followed by NICE fiasco, part 2. Rawlins should withdraw guidance and start again.

Since then, something of a maelstrom has engulfed NICE, so it’s time for an update.

It isn’t only those who are appalled that NHS should endorse voodoo medicine on the basis of very slim evidence who are asking NICE to rethink their guidance on low back pain. Pain specialists are up in arms too, and have even started a blog, ‘Not Nearly as NICE as you think …‘, to express their views. Equally adverse opinions are being expressed in the Britsh Medical Journal. A letter there is signed by over 50 specialists in pain medicine. It ends thus

“Because of these new guidelines patients will continue to experience unnecessary pain and suffering and their rights to appropriately individually tailored treatment have been removed on the basis of a flawed analysis of available evidence. We believe the guidelines do not reflect best practice, remove patient choice and are not in our patients’ best interests.”

In a contribution headed “NICE misguidance”. Dr Michel Vagg ends

It seems to me that this guideline has been used as a propaganda vehicle to allow cherry-picked evidence to be enshrined as doctrine. This is an abuse of the guideline development process . . . ”

I have to say, though, that it seems to me that some of these people are promoting their own interests as much as chiropractors and acupuncturists. The evidence that spinal injections produce worthwhile benefits seems to be as thin as the evidence that chiropractic and acupuncture produce worthwhile benefits. But no doubt the injections are good for the budgets of PCTs or private practice doctors.. Could it perhaps be the case that some of the clinicians’ anger is being generated by doctors who are rushing to defend their own favourite ineffective treatment?

Why, oh why, can’t either NICE or the pain consultants bring themselves to state the obvious, that nothing works very well. The only thing that can be said for most of the regular treatments is that although they may not be much more effective than acupuncture or chiropractic, at least they don’t come with the intellectually-offensive hokum that accompanies the latter. Very sensible attempts have been made to identify the cause of low back pain [reviewed here], Occasionally they succeed. Mostly they don’t.

One clinician’s letter deserves special attention because it goes into the evidence, and the costs, in some detail. Its conclusions are very different from those in the NICE guidance.

The letter, a Review of NICE guidance, is from Dr C.J.D. Wells [download the whole letter].   He is a pain relief consultant from Liverpool.

Let’s look at some highlights.

Wells points out the absurdity of the cost estimates

“In the pricing section, they estimate that this will require an increase of facilities so that 3,500 patients can be treated instead of 1,000 at present (again see comments on pricing). This is not many treatments for the 20 million sufferers, of whom we can estimate that at least 2 million will have significant long-term disability and psychological distress”

And that is without even costing all the secondary costs of miseducating a new generation of students in fables about “Qi”, meridians, energy flow, subluxations and innate intelligence.

“The abysmal ignorance of the committee is reflected in the poor overall advice. So if you have a committee with special interests in Exercise, Manipulation, PMP’s, and Surgery, and you call an expert on Acupuncture, you get advice to use Exercise, Manipulation, Acupuncture, PMP’s and Surgery. Amazing.”

Another pain consutant, Charles Guaci, says in a comment in the Daily Mail.

I am a Pain Consultant of 30 years experience, have published two books (one translated into different languages).

NICE never asked me for my opinion.

This is the most ridicuculous pseudo-scientific document I have ever seen.

The panel consisted of a surgeon, psychologist, osteopath, acupuncturist a physiotherapist and an academic; not one pain consultant! The conclusions are simply a means of increasing the employment of their friends!

All evidence submitted to NICE was ignored.

It is almost certain than unless NICE rethink their ideas that Pain Consultants will be seeking a judicial review as well as full disclosure of how the panel arrived at their bizarre findings under the Freedom of information act.

Patients should realise that they are being taken for a ride.

Despite the outcry from opponents of magic medicine and from pain specialists, the assessment by the normally excellent NHS Choices site was disappointing. It made no mention at all of the secondary consequences of recommending CAM and described the assertions of the guidance group quite uncritically.

The reputation of NICE

NICE has been criticised before, though usually unjustly. In the past I have often supported them. For example. when NICE said that treatment of dementia with anticholinesterase drugs like galantamine was ineffective, there was a great outcry, but NICE were quite right. There is little or no rationale for such treatments, and more importantly, very little evidence that they work. But patients, especially when they are desperate, have greater faith in drug treatments than most pharmacologists, They want to clutch at straws. A bit like the NICE guidance committee, faced with a bunch of treatments most of which are almost ineffective, clutched at the straws of acupuncture and chiropractic. But this time it isn’t only the patients who are cross. It is most of the medical and scientific world too.

One interpretation of these bizarre events is that they represent a case of medical/scientific arrogance. Ben Goldacre wrote of another aspect of the same problem thus week, in Dodgy academic PR [download the paper on which this is based].

The first job of a scientist is to say openly when the answer to a question is not known. But scientists are under constant pressure to exaggerate the importance of their results. Last year we published an article which I feel may, if verified, turn out to be the second most important that I have ever been an author on. Because it happened to be published in Nature (not because of its quality), a press release was written (by an arts graduate!). It took some argument to prevent the distorted and exaggerated account being imposed on the public. This is typical of the sort of thing reported in Goldacre’s column. I reported a similar case a while ago, Why honey isn’t a wonder cough cure: more academic spin.

If NICE does not reconsider this guidance, it is hard to see how it can be taken seriously in the future. I hope that when NICE’s director, Professor Sir Michael Rawlins, returns from his trips abroad, he will find time to look at the case himself.

Indirectly, then, it can be argued that NICE’s bizarre guidance is just another manifestation of the management of science being passed from the hands of scientists into the hands of administrators and spin experts. It is yet another example of DC’s rule

Never trust anyone who uses the word ‘stakeholder’

Some bone-headed bureaucrat decides that any charlatan or quack is a ‘stakeholder’ in the provision of NHS care and gives them a quite disproportionate say in how taxpayers’ money is spent. The bureaucrats are so busy following processes and procedures, ticking boxes, and so deficient in scientific education, that they failed to notice that they’ve been caught out by the old trick of used car salesmen, bait and switch.

The consequences

The expected consequences have already started to materialise. The Prince of Wales’ Foundation for Magic Medicine is jubilant about having been endorsed by NICE. And I’m told that “The chiropractors have now just written letters to all health boards in Scotland asking for contracts for their services to deal with back pain”.

There could hardly have been a worse time for NICE to endorse chiropractic. We are in the middle of a storm about free speech because of the disgraceful action of the British Chiropractic Associaton in suing one of our best science writers, Simon Singh, for defamation because he had the temerity to express an opinion, Of course, even if the BCA wins in court, it will be the overall loser, because chiropractic claims are now being scrutinised as never before (just look at what they told me).

Follow-up

A much-cited paper. The paper that is most often cited by chiropractors who claim to be able to cure colic by spinal manipulation is 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. This is not easy to get hold of but Steve Vogel has sent me s scanned copy which you can download here. 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 reaearch in chiropractic that anyone should think this paper worth mentioning at all.

June 6 2009. More flak for NICE from the Royal College of Anaesthetists, and more adverse comment in the BMJ. And of course the blogs. for example, “If this is “evidence based medicine” I want my old job back“.

“Acupuncture on the NHS: a dangerous precedent”: a good analysis at counterknowledge.com.

June 6 2009, Comment sent to the BMJ. The comment was submitted, as below, early on Friday 5th June. The BMJ said it was a “sensitive issue” and for the next five days lawyers pondered over it.

Underwood and Littlejohns describe their guidance as being a “landmark”. I can only agree with that description. It is the first time that NICE has ever endorsed alternative medicine in the face of all the evidence. The guidance group could hardly have picked a worse moment to endorse chiropractic. Chiropractors find it so hard to find evidence for their practices that, when one of our finest science writers, Simon Singh, asked to see the evidence they sued him for defamation. I suggest that the guidance group should look at the formidable list of people who are supporting Singh, after his brave decision to appeal against this iniquitous persecution.

Of course I’m sure this bizarre decision has nothing to do with the presence on the guidance group of Peter Dixon, chair of the General Chiropractic Council. Nevertheless, I am curious to know why it is that when I telephoned two of the practices belonging to Peter Dixon Associates, I was told that they could probably treat infantile colic and asthma. Such claims have just been condemned by the Advertising Standards Authority.

The low back pain guidance stands a good chance of destroying NICE’s previously excellent reputation for dispassionate assessment of benefits and costs. Yes, that is indeed a landmark of sorts.

If NICE is ever to recover its reputation, I think that it will have to start again. Next time it will have to admit openly that none of the treatments work very well in most cases. And it will have to recognise properly the disastrous cultural consequences of giving endorsement to people who, when asked to produce evidence, resort to legal intimidation.

Eventually, on Wednesday 10 June the comment appeared in the BMJ, and it wasn’t greatly changed. Nevertheless if is yet another example of legal chill. This is the final version.

One wonders whether this bizarre decision by NICE has anything to do with the presence on the guidance group of Peter Dixon, chair of the General Chiropractic Council.

Bait and switch. Oh dear, oh dear. Just look at this. British Chiropractic Association tell their members to hide their sins from prying eyes.

Excellent round-up of the recent outburst of writing about “chiroquacktic” (Tut, tut, is there no respect?).

Dr Crippen writes “NICE recommends a cure for all known disease” [Ed some exaggeration, surely]

15 Responses to The NICE fiasco, Part 3. Too many vested interests, not enough honesty

  • I wish to make two points:

    Firstly, spinal injections and TENS are rejected by NICE (both treatments used in pain management), but acupuncture and manipulation are accepted. Yet the latter are no more proven to be effective than the former.

    It is convenient that no pain consultants were on the NICE committee (and their attempts at advising the committee were rebuffed) as had they been on the NICE team, their treatments would have likely been included and that would have blown the costing plan out of the water.

    Secondly, despite the difficulty in accurately diagnosing specific sources of back pain (joints, discs etc.), it is illogical to assume there is no patho-anatomical damage of any kind.

    Knee pain is often attributed to early OA changes (minor trauma = inflammation = pain) and I cannot see how this doesn’t apply also to the spine in many middle-aged patients.

    However, the self-limiting nature of back pain suggests that self-care is the most appropriate therapy in these cases. Physical therapy should be restricted to advice, reassurance and exercises to maintain flexibility and muscle support.

    The argument can be made that acupuncture, manual therapy, spinal injections are all ‘Voltaire-type’ treatments, i.e. they entertain the patient whilst nature takes its course.

    The counter argument is that patients do not want to wait until natural resolution, but want contemporaneous pain relief (be it placebo or not).

    It seems that the NICE guidelines team have decided to advocate for the patient’s desire for short-term therapies, which conveniently suit the very professionals that offer them.

  • It is quite ironic that NICE suggests that X-raying patients is inappropriate, but are quite happy to pack patients off to chiropractors where X-rays are used as a sales tool.

  • Malachu
    Good to hear from the NHS physiotherapist again, and good to agree with you pretty much completely. The guidance is quite spectacularly barmy.

    lecanardnoir
    Very good point about X-rays. tt is just one of many secondary consequences of the guidance that the NICE group ignored. Of course I’m sure that is nothing to do with the fact that the chairman of the GCC was one of those who wrote the advice.

  • One of the problems here seems to have been an over-optimistic interpretation of results from clincial trials and systematic reviews. I notice that the Guideline Development Group did not include a statistician or specialist in these research methodologies, which seems a rather foolish omission on the part of NICE, given that there is a lot of dodgy evidence in this area. Could be a suggestion there for them to take to future guideline groups?

  • Our friends over in ChiroWorld are standing on their wounded dignity, David.

    “Repeatedly, Ernst has spoken out on what he perceives to be the dangers of what he disrespectfully calls ‘chiropractic therapy’. Ernst widely disseminates his view that chiropractic can cause stroke and death, despite strong evidence to show that undergoing spinal manipulation from a chiropractor or osteopath is no more dangerous than visiting a GP.”

    “Strong evidence”? Hmmm.

    I find it difficult to believe that chiropractic spinal manipulation is “no more dangerous” than sitting in a GP’s chair and/or getting physical examination. Could this perhaps be an example of misunderstood (or even manipulated) statistics, notably the statistics of rare events?

  • PS And why is it disrespectful to call it “chiropractic therapy”?

  • Oh dear, every time a chiropractor opens his mouth he seems to dig himself deeper into a hole.

    It really seems more and more likely that the attempt by the British Chiropractic Association to suppress freedom of speech will succeed in bringing to public attention the baselessness of their claims more effectively than any sceptic could have done.

    I find it hard now to see why we need chiropractors at all. If you think that manipulation might help low back pain, skip the hokum and go to a physiotherapist.

  • NICE guidelines
    The assumption is that manipulation equals chiropractic. But, as stated in the report, it could be manipulation by osteopaths (no “subluxations”) or physiotherapists

  • @butterfingers
    Exactly. So why not put all manipulation in the hands of physiotherapists? Its efficacy may be uncertain but at least they don’t believe in black magic.
