Arguably the most prestigious medical journal in the world, the New England Journal of Medicine regularly features articles over which pharmaceutical companies and their employees can exert significant influence. Over a year-long period ending in August, NEJM published 73 articles on original studies of new drugs, encompassing drugs approved by the FDA since 2000 and experimental drugs. Of those articles, 60 were funded by a pharmaceutical company, 50 were co-written by drug company employees and 37 had a lead author, typically an academic, who had previously accepted outside compensation from the sponsoring drug company in the form of consultant pay, grants or speaker fees. The New England Journal of Medicine is not alone in featuring research sponsored in large part by drug companies - it has become a common practice that reflects the growing role of industry money in research. Years ago, the government funded a larger share of such experiments. But since about the mid-1980s, research funding by pharmaceutical firms has exceeded what the National Institutes of Health spends. Last year, the industry spent $39 billion on research in the United States while NIH spent $31 billion. When the company is footing the bill, the opportunities for bias are manifold: Company executives seeking to promote their drugs can design research that makes their products look better. They can select like-minded academics to perform the work. And they can run the statistics in ways that make their own drugs look better than they are. If troubling signs about a drug arise, they can steer clear of further exploration.
