Physicians' Perspectives On FDA Regulation Of Drugs And Medical Devices: A National Survey.

ABSTRACT

Physicians' knowledge of Food and Drug Administration (FDA) approval processes is important in informing clinical decisions and patient discussions. Among a randomly selected national sample of 509 internists, cardiologists, and oncologists, 41 percent reported moderate or better understanding of the FDA's drug approval process, and 17 percent reported moderate or better understanding of the FDA's medical device approval process. Nearly all physicians thought that randomized, blinded trials that met primary endpoints should be very important factors required to secure regulatory approval. Also, nearly all physicians thought that the FDA should revoke approval for accelerated-approval drugs or breakthrough devices that did not show benefit in postapproval studies. Our findings suggest that physicians commonly lack familiarity with drug and medical device regulatory practices and are under the impression that the data supporting FDA drug and high-risk device approvals are more rigorous than they often are. Physicians would value more rigorous premarket evidence, as well as regulatory action for drugs and devices that do not demonstrate safety and effectiveness in the postmarket setting.
