Spleen

Having missed World Homeopathy Awareness Week (yet again) I'm reading the UK Commons Science & Technology Committee's 275 page report [PDF] on its Homeopathy inquiry.

The Committee comments that -
that the NHS should cease funding homeopathy. It also concludes that the Medicines and Healthcare products Regulatory Agency (MHRA) should not allow homeopathic product labels to make medical claims without evidence of efficacy. As they are not medicines, homeopathic products should no longer be licensed by the MHRA.

The Committee carried out an evidence check to test if the Government's policies on homeopathy were based on sound evidence. The Committee found a mismatch between the evidence and policy. While the Government acknowledges there is no evidence that homeopathy works beyond the placebo effect (where a patient gets better because of their belief in the treatment), it does not intend to change or review its policies on NHS funding of homeopathy.
In releasing its report it stated that -
The Committee concurred with the Government that the evidence base shows that homeopathy is not efficacious (that is, it does not work beyond the placebo effect) and that explanations for why homeopathy would work are scientifically implausible.

The Committee concluded - given that the existing scientific literature showed no good evidence of efficacy - that further clinical trials of homeopathy could not be justified.

In the Committee's view, homeopathy is a placebo treatment and the Government should have a policy on prescribing placebos. The Government is reluctant to address the appropriateness and ethics of prescribing placebos to patients, which usually relies on some degree of patient deception. Prescribing of placebos is not consistent with informed patient choice-which the Government claims is very important-as it means patients do not have all the information needed to make choice meaningful.

Beyond ethical issues and the integrity of the doctor-patient relationship, prescribing pure placebos is bad medicine. Their effect is unreliable and unpredictable and cannot form the sole basis of any treatment on the NHS.
The Committee chair stated that -
It sets an unfortunate precedent for the Department of Health to consider that the existence of a community which believes that homeopathy works is 'evidence' enough to continue spending public money on it. This also sends out a confused message, and has potentially harmful consequences. We await the Government's response to our report with interest.
Oliver Wendell Holmes - the essayist and doctor (1809–1894), not his son the jurist - more pungently commented in Homeopathy & Its Kindred Delusions: Two lectures delivered before the Boston Society for the Diffusion of Useful Knowledge (1842) that -
It may be thought that a direct attack upon the pretensions of Homeopathy is an uncalled-for aggression upon an unoffending doctrine and its peaceful advocates. ... Such is the pretended science of Homeopathy, to which you are asked to trust your lives and the lives of those dearest to you. A mingled mass of perverse ingenuity, of tinsel erudition, of imbecile credulity, and of artful misrepresentation, too often mingled in practice, if we may trust the authority of its founder, with heartless and shameless imposition. Because it is suffered so often to appeal unanswered to the public, because it has its journals, its patrons, its apostles, some are weak enough to suppose it can escape the inevitable doom of utter disgrace and oblivion. ... If it should claim a longer existence, it can only be by falling into the hands of the sordid wretches who wring their bread from the cold grasp of disease and death in the hovels of ignorant poverty.
I note the Trustees of the Prince of Wales' Foundation for Integrated Health - an organisation vigorous in spreading the word about alternative medicine - have "decided to close the charity" after a spot of misbehaviour within the Foundation. they explain that "Whilst the closure has been planned for many months and is part of an agreed strategy, the Trustees have brought forward the closure timetable as a result of a fraud investigation at the charity."
