Physician Skepticism About Industry-Funded Clinical Trials
In a recent New England Journal of Medicine article “A randomized study of how physicians interpret research funding disclosures” Dr. Kesselheim and colleagues found that internists harbor mistrust of industry-funded clinical trials. In his accompanying editorial, Dr. Jeffrey Drazen states that “how trials influence practice should be based on the quality of the information conveyed in the full study report” without regard for funding source.
While we applaud the efforts of the Journal to enhance transparency by posting study protocols on-line, we believe that it is appropriate for physicians to discount the findings of industry-funded trials. Vioxx litigation has demonstrated that even editors may fail to discern bias in reports of industry-funded trials. Clinicians who lack training in trial methodology and results interpretation are ill-equipped to detect bias, even if they read the full study protocol.
Further, clinicians are unlikely to access full protocols; many in fact read only study abstracts. Routine conflict of interest (COI) disclosure is fundamentally designed to allow readers to weigh biases which may influence the generation and presentation of data. Kesselheim and colleagues demonstrated that COI disclosure can trigger appropriate physician skepticism and accomplish what it is intended to do.
Dr. Salomeh Keyhani is an Assistant Professor in the Division of General Internal Medicine at the University of California, San Francisco. She is also a staff physician in the San Francisco VA Medical Center. Her research interests include the examination of the quality of health care services and health care policy research. Her quality of care research to date has focused on examining the underuse and overuse of medical procedures. Her policy research has largely focused on areas important to health care reform. She has surveyed physicians on their views regarding coverage expansions (the public option and Medicare expansions), defensive medicine, comparative effectiveness research and reimbursement reform.
