This NYRB article is well worth reading. The scale of the problem seems extraordinary:
No one knows the total amount provided by drug companies to physicians, but I estimate from the annual reports of the top nine US drug companies that it comes to tens of billions of dollars a year. By such means, the pharmaceutical industry has gained enormous control over how doctors evaluate and use its own products. Its extensive ties to physicians, particularly senior faculty at prestigious medical schools, affect the results of research, the way medicine is practiced, and even the definition of what constitutes a disease.
And the links are widespread:
A recent survey found that about two thirds of academic medical centers hold equity interest in companies that sponsor research within the same institution. A study of medical school department chairs found that two thirds received departmental income from drug companies and three fifths received personal income. In the 1980s medical schools began to issue guidelines governing faculty conflicts of interest but they are highly variable, generally quite permissive, and loosely enforced.
Accentuate the positive:
A review of seventy-four clinical trials of antidepressants, for example, found that thirty-seven of thirty-eight positive studies were published. But of the thirty-six negative studies, thirty-three were either not published or published in a form that conveyed a positive outcome. It is not unusual for a published paper to shift the focus from the drug’s intended effect to a secondary effect that seems more favorable.
A staggering example:
In 2004, after the National Cholesterol Education Program called for sharply lowering the desired levels of “bad” cholesterol, it was revealed that eight of nine members of the panel writing the recommendations had financial ties to the makers of cholesterol-lowering drugs. Of the 170 contributors to the most recent edition of the American Psychiatric Association’sDiagnostic and Statistical Manual of Mental Disorders (DSM), ninety-five had financial ties to drug companies, including all of the contributors to the sections on mood disorders and schizophrenia. Perhaps most important, many members of the standing committees of experts that advise the FDA on drug approvals also have financial ties to the pharmaceutical industry.
Mental illness is a particularly problematic area:
Shyness as a psychiatric illness made its debut as “social phobia” in DSM-III in 1980, but was said to be rare. By 1994, when DSM-IV was published, it had become “social anxiety disorder,” now said to be extremely common. According to Lane, GlaxoSmithKline, hoping to boost sales for its antidepressant, Paxil, decided to promote social anxiety disorder as “a severe medical condition.” In 1999, the company received FDA approval to market the drug for social anxiety disorder. It launched an extensive media campaign to do it, including posters in bus shelters across the country showing forlorn individuals and the words “Imagine being allergic to people…,” and sales soared. Barry Brand, Paxil’s product director, was quoted as saying, “Every marketer’s dream is to find an unidentified or unknown market and develop it. That’s what we were able to do with social anxiety disorder.”
As I say, well worth reading. I’d love to see a drug company response.
