A survey of hospital review boards that watchdog experiments on patients shows that one in three members takes money from companies that make drugs and medical devices that come under study.
What's more, many of those with conflicts rarely or never disclose their financial ties, according to the study led by Eric Campbell of Massachusetts General Hospital and Harvard Medical School.
The study of 100 university medical centers is said to be the first to look at financial conflicts of interest on hospitals' institutional review boards. The review boards are little-known committees responsible for protecting patients in research experiments.
