Critics of homeopathy (and CAM) repeat endlessly there is ‘no evidence’ that they work beyond placebo and therefore homeopathy should not be funded by the NHS.

This disingenuously gives the entirely false impression to the public that all NHS-funded medical interventions are obviously evidence based. This is not only false, buy it is light years from the truth.

The Pie Man exists to remind critics of homeopathy and CAM that most interventions employed by doctors (on the NHS and elsewhere) are certainly not evidence-based. As always I defer to the British Medical Journal’s highly-esteemed handbook called Clinical Evidence.

The reason I’m writing about the Pie Man today is that the figures have changed. Unfortunately for people like Edzard Ernst, cialis Michael Baum, prescription Simon Singh, Ben Goldacre et al, that use EBM (evidence based medicine) as a tool to attack homeopathy and CAM exclusively, the case for orthodox medicine being evidence-based just got a whole lot worse.

Here is the Pie Man as first published a year ago.

Here are the the latest figures from Clinical Evidence which makes the Pie Man look like this:

And here are a comparison of those figures

Proportions of Commonly-used Treatments supported by Good Evidence

March 2009 Today

Beneficial 13% 11%
Likely to be beneficial 23% 23%
Trade off between benefits and harm 8% 7%
Unlikely to be beneficial 6% 5%
Likely to be ineffective or harmful 4% 3%
Unknown effectiveness 46% 51%

This means the big loser in recent changes are treatments proven to be incontrovertibly beneficial (15% loss of its share) and the big winner was ‘Unknown effectiveness’ (gain of nearly 10%).

So next time you hear a doctor criticise homeopathy for lacking evidence, know that s/he is a doctor in a glass house throwing stones and ask him or her quietly what % of conventional interventions on the NHS are fully evidence based.
