Some warnings from the US Food and Drug Administration (FDA) about potential medication safety issues have a substantial effect on clinician behavior while others have little influence, according to a systematic review of studies probing the effects of specific FDA risk communications.
Stacie B. Dusetzina, PhD, of the department of health care policy at Harvard Medical School in Boston, and a multi-institution team of colleagues examined the impact of FDA risk communications on health care use and found that the effectiveness of these messages depends on the type of recommendation, whether other effective therapies are available, and how often the messages were repeated (Dusetzina SB et al. Med Care. doi:10.1097/MLR.0b013e318245a160 [published online January 18, 2012]).
