In a report published today, the Science and Technology Committee concludes 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.
Nice when people get things right.
That Evidence Check report I mentioned yesterday is now available, and Ben Goldacre shares the full release. As he says, looks like pretty sensible stuff. It’s not medicine; homeopathic pills are just sugar; lying to patients about placebos is not okay. That kind of thing.
Ben also made a good point on Twitter earlier – while the problem with accepting homeopathy as medicine is often cited as a “lack of evidence”, in fact we have a great deal of very solid and reliable evidence. That it doesn’t work. It’s like saying “Well, maybe this elephant will be able to fly… It doesn’t look like any of them can at the moment, but we just don’t have enough evidence.”
Le Canard Noir is all over this, of course, looking through the whole thing in great detail. I’m glad that the authors of the report seem to understand this point:
We do not doubt that homeopathy makes some patients feel better. However, patient satisfaction can occur through a placebo effect alone and therefore does not prove the efficacy of homeopathic interventions.
And, as anaglyph reminded me yesterday, you don’t even need a particular placebo effect to just start to feel better over time, and be tempted to confuse correlation with causation as you simply regress to the mean.
Also reporting on this is gimpy, who quotes a comment from a homeopath named Carol Boyce that made me grind my teeth just a little:
Mr Stewart made a valiant attempt to to [sic] bring balance to the proceedings but was hopelessly outnumbered.
A question needs to be asked in parliament about the conduct of this Evidence Check and it’s [sic] inherent bias.
It’s almost impossible to hear a phrase like “bring balance to the proceedings” and not imagine that this must be a good thing to do, restoring some necessary fairness. But nonsense doesn’t deserve to be fairly balanced with science, and if nonsense is all you have on your side then it’s entirely right that things should be biased against you. That’s another thing that’s meant to sound like it’s inherently negative and unfair and unacceptable, “bias”. And there are many cases where bias is unjustified and should be fought against. But there are some cases where it’s proper and necessary.
I’m biased strongly in favour of eating pasta instead of rat poison. I’m also biased strongly in favour of spending tax money on medicine instead of homeopathy.
This is all being covered in more depth by various intrepid investigative blogojournalists (there just isn’t a comfortable “blogger+journalist” portmanteau), and I’m pretty sure Martin Robbins is planning to have his own round-up of events soon too. (Edit 23/02/10: Yep.) I’m still only really a commentator a rung or two below, only joining in the chatter a little later once all the big players have done the real legwork, but that’s okay. This way I get to be lazy and still feel like I’m joining in.
