The cornerstone of science-based medicine is, of course, scientific research. The integrity and quality of biomedical research is therefore of critical importance and to be thoughtfully and jealously guarded, if we care about maintaining an optimal standard of care. There are many threats and hazards to the institutions of medical research – mostly ideological. One that has not been discussed much on this blog but has been in the news recently is that of conflict of interest. Upon close examination this is a more complex issue than it may at first appear.
The most recent controversy over conflicts of interest were sparked by an article published in JAMA in which the authors allege that published studies that downplayed the risks of Vioxx (A Cox-2 inhibitor marketed as a pain killer that was removed from the market for increased cardiac risk) were in fact ghost-written by employees of Merck, the manufacturer of Vioxx. The names of two academic researchers were then attached to the studies to give them legitimacy. If true this is a damning episode, and no one would reasonably disagree with the contention that companies writing research on their own products represents an unacceptable conflict of interest. For the record, both Merk and the one surviving academic deny the accusations completely.
