The purpose of the study was to compare utilization of conventional psychotropic drugs among patients seeking care for anxiety and depression disorders (ADDs) from general practitioners (GPs) who
- strictly prescribe conventional medicines (GP-CM),
- regularly prescribe homeopathy in a mixed practice (GP-Mx),
- or are certified homeopathic GPs (GP-Ho).
The investigation was an epidemiological cohort study of general practice in France, which included GPs and their patients consulting for ADDs (scoring 9 or more in the Hospital Anxiety and Depression Scale, HADS). Information on all medication utilization was obtained by a standardised telephone interview at inclusion, 1, 3 and 12 months.
Of 1562 eligible patients consulting for ADDs, 710 (45.5 %) agreed to participate. Adjusted multivariate analyses showed that GP-Ho and GP-Mx patients were less likely to use psychotropic drugs over 12 months, compared to GP-CM patients. The rate of clinical improvement (HADS <9) was marginally superior for the GP-Ho group as compared to the GP-CM group, but not for the GP-Mx group.
The authors concluded that patients with ADD, who chose to consult GPs prescribing homeopathy reported less use of psychotropic drugs, and were marginally more likely to experience clinical improvement, than patients managed with conventional care. Results may reflect differences in physicians’ management and patients’ preferences as well as statistical regression to the mean.
Aren’t we glad they added the last sentence to their conclusion!!!
Without it, one might have thought that the observed differences were due to the homeopathic remedies. In fact, the finding amounts to a self-fulfilling prophecy: Homeopaths tend to be against prescribing conventional drugs. This means that patients consulting homeopaths are bound to use less drugs than patients who consult conventional doctors. In that sense, the study was like monitoring whether consumers who go to the butchers buy more meat than those shopping in a shop for vegetarians.
The only result that requires a more serious consideration is that homeopathically treated patients experienced more clinical improvement than those treated conventionally. But even this difference is not hard to explain: firstly, the difference was merely marginal; secondly, patients with ADD are bound to respond particularly well to the empathetic and long therapeutic encounter most homeopaths offer. In other words, the difference had nothing to do with the alleged effectiveness of the homeopathic remedies.
