The Pharmaceutical Industry and Doctors’ Prescribing Habits

An interesting talk on the Australian Broadcasting Commission ‘Ockhams’Razor’ radio program about the marketing of (legal) drugs by big pharma through the medical establishment. The speaker is Professor Christopher Norden, from Adelaide Hospital and the Institute of Medical and Veterinary Sciences. He talks of his own experience of the many incentives offered to practitioners by pharmaceutical companies to prescribe their wares.

From Professor Norden’s talk:

"It is about a hundred years since that great Canadian-born physician Sir William Osler, Regius Professor of Medicine in Oxford, complained about the increasing influence of the pharmaceutical industry on the medical profession. If he knew how this influence had increased since then, he would be turning in his grave at the way the industry now dominates doctors’ prescribing habits. It does this not only by direct and indirect pressure on the doctors themselves, but also by encouraging the public to ask for scripts and to demand that governments provide the money."

The Placebo Effect and Exercise

“In a study testing whether the relationship between exercise and health is moderated by one’s mindset, 84 female room attendants working in seven different hotels were measured on physiological health variables affected by exercise. Those in the informed condition were told that the work they do (cleaning hotel rooms) is good exercise and satisfies the Surgeon General’s recommendations for an active lifestyle. Examples of how their work was exercise were provided. Subjects in the control group were not given this information. Although actual behavior did not change, 4 weeks after the intervention, the informed group perceived themselves to be getting significantly more exercise than before. As a result, compared with the control group, they showed a decrease in weight, blood pressure, body fat, waist-to-hip ratio, and body mass index. These results support the hypothesis that exercise affects health in part or in whole via the placebo effect.”
