It has been reported that Belgium has just officially recognised homeopathy. The government had given the green light already in July last year, but the Royal Decree has only now become official. This means that, from now on, Belgian doctors, dentists and midwives can only call themselves homeopaths, if they have attended recognised courses in homeopathy and are officially certified. While much of the new regulation is as yet unclear (at least to me), it seems that, in future, only doctors, dentists and midwives are allowed to practice homeopathy, according to one source.
However, the new law also seems to provide that those clinicians with a Bachelor degree in health care who have already been practicing as homeopaths can continue their activities under a temporary measure.
Moreover, the official recognition as a homeopath does not automatically imply that the services will be refunded from a health insurance.
It is said that, in general, homeopaths are happy with the new regulation; they are delighted to have been up-graded in this way and argue that the changes will result in higher quality standards: “This is a very important step and it can only be to the benefit of the patients’ safety. Patients will know whether or not they are dealing with someone who correctly applies homeopathic medicine”, Leon Schepers of the Unio Homeopathica Belgica was quoted saying.
The delight of homeopaths is in sharp contrast to the dismay of rational thinkers. The NHMRC recently assessed the effectiveness of homeopathy. The evaluation is both comprehensive and independent; it concluded that “the evidence from research in humans does not show that homeopathy is effective for treating the range of health conditions considered.” In other words, homeopathic remedies are implausible, over-priced placebos.
Granting an official status to homeopaths cannot possibly benefit patients. On the contrary, it will only render health care less effective and charlatans more assertive.
Can anyone think of celebrities promoting conventional treatments? Jane Fonda advertising blood pressure control? Brad Pit advocating early intervention after stroke? Boris Johnson making sure that diabetics check their metabolic control? Angelina Jollie suggesting that we all immunise our kids? Well, I cannot - not many anyway. But I certainly could list numerous VIPs doing their very best to promote quackery and anti-vaccination propaganda.
We may smile about such vain attempts to catch the lime-light, but the influence of celebrities on consumers’ behaviour might be huge and detrimental. It is difficult to estimate, and I am not aware of much reliable research data in this area. But my instinct tells me that, in the realm of alternative medicine, the ‘celebrity-factor’ is a very strong determinant of alternative medicine usage, and one that significantly contributes to the ‘sea of misinformation’ in this area.
With one of our research projects at Exeter, we wanted to identify reports on celebrities’ use of alternative medicine. We searched our department’s extensive data files, the Internet via the Google search engine, and the UK popular press via LexisNexis using the search terms “celebrity”, “alternative medicine” and “complementary medicine”. We considered articles published during 2005 and 2006 for inclusion in our study.
Using this strategy, we identified 38 celebrities using a wide range of alternative medicine interventions. Homeopathy, acupuncture and Ayurveda were the most popular modalities. The conclusion we drew from this investigation was that there may be many reasons why consumers use alternative medicine, and wanting to imitate their idols is one of them.
Some pro-alternative sites even boast with the fact that celebrities use quackery: Oprah is into it; so are Madonna, Uma and Gwyneth. No, it’s not a club for high-profile women with unique names. It’s alternative medicine. As ABC News describes, alternative medicine remains an option outside of “standard care” practices that physicians employ. But it has had a sweeping effect on the country, and celebrities have played a role in its popularity.
This, I think, indicates that celebrities are being used as a marketing tool for the alternative medicine industry. Both seem to feed of each other: the industry turns the celebrity endorsements into profit, and the celebrities turn the interest of the press into the all-important fame needed for remaining a celebrity. If a star displays her shapely back in a low-cut dress, nobody bats an eyelash; if, however, her back is covered with marks from today’s cupping-therapy, the press goes crazy – and, as a consequence, cupping therapy experiences a boost. The fact that there is no good evidence for this treatment becomes entirely irrelevant, and so is the fact that thousands of people will hence forward waste their money on ineffective treatments, some of them possibly even losing valuable time for curing a life-threatening disease.
Who wants such a pedestrian thing as evidence? We are in the realm of the high-fliers who cannot be bothered with such trivialities – unless, of course, they are really ill, in which case they will not consult their local quack but use the best conventional medicine on offer. Has anyone heard of a member of the Royal family being rushed to a homeopathic hospital when acutely ill?
In my experience, a VIP’s conviction in promoting quackery is inversely correlated to his expertise and intelligence. Prince Charles seems to want the entire British nation to be force-fed on quackery – anything from Gerson diet to homeopathy. He knows virtually nothing about medicine, but makes up for this deficit through a strong and quasi-religious belief in quackery. Scientists tend to laugh about his quest and might say with a slightly pitiful smile “but he is full of good will!”. Yet I am not sure that it is all that funny, nor am I convinced that good will is enough. Misleading the public about matters of health care is not amusing. And good will and conviction render quacks not less but more dangerous.
Even though I have not yet posted a single article on this subject, it already proved to be a most controversial subject in the comments section. A new analysis of the evidence has just been published, and, in view of the news just out of a Royal Charter for the UK College of Chiropractors, it is time to dedicate some real attention to this important issue.
The analysis comes in the form of a systematic review authored by an international team of chiropractors (we should not fear therefore that the authors have an “anti-chiro bias”). Their declared aim was “to determine whether conclusive evidence of a strong association [between neck manipulation and vascular accidents] exists”. The authors make it clear that they only considered case-control studies and omitted all other articles.
They found 4 such publications all of which had methodological limitations. Two studies were of acceptable quality, and one of these studies seemed to show an association between neck manipulation and stroke, while the other one did not. The authors’ conclusion is ambivalent: “Conclusive evidence is lacking for a strong association between neck manipulation and stroke, but it is also lacking for no association”.
The 4 case-control studies, their strength and weaknesses are, of course, well-known and have been discussed several times before. It was also known that the totality of these data fail to provide a clear picture. I would therefore argue that, in such a situation, we need to include further evidence in an attempt to advance the discussion.
Generally speaking, whenever we assess therapeutic safety, we must not ignore case-reports. One might be next to meaningless but collectively they can provide strong indicators of risk. In drug research, for instance, they send invaluable signals about potential problems and many drugs have been withdrawn from the market purely on the basis of case-reports. If we include case-reports in an analysis of the risks of neck manipulations, the evidence generated by the existing case-control studies appears in a very different light. There are virtually hundreds of cases where neck manipulations have seriously injured patients, and many have suffered permanent neurological deficits or worse. Whenever causation is validated by experts who are not chiropractors and thus not burdened with a professional bias, investigators find that most of the criteria for a causal relationship are fulfilled.
While the omission of case-reports in the new review is regrettable, I find many of the staements of the authors helpful and commendable, particularly considering that they are chiropractors. They seem to be aware that, when there is genuine uncertainty, we ought to err on the safe side [the precautionary principle]. Crucially, they comment on the practical implications of our existing knowledge: “Considering this uncertainty, informed consent is warranted for cervical spinal manipulative therapy that advises patients of a possible increase in the risk of a rare form of stroke…” A little later, in their discussion they write: “As the possibility of an association between cervical spinal manipulative therapy and vascular accidents cannot be ruled out, practitioners of cervical spinal manipulative therapy are obliged to take all reasonable steps that aim to minimise the potential risk of stroke. There is evidence that cervical rotation places greater stresses on vertebral arteries than other movements such as lateral flexion, and so it would seem wise to avoid techniques that involve full rotation of the head.”
At this point it is, I think, important to note that UK chiropractors tend not to obtain informed consent from their patients. This is, of course, a grave breach of medical ethics. It becomes even graver, when we consider that the GCC seems to do nothing about it, even though it has been known for many years.
Is this profession really worthy of a Royal Charter? This and the other question raised here require some serious consideration and discussion which, no doubt, will follow this short post.
