Emergency physicians who have the greatest fear of malpractice suits are more likely than their colleagues to admit and order tests for patients with chest pain or other heart symptoms, even if those patients are at low risk for actual problems, according to a study led by a University of Iowa researcher.

These findings were based on surveys of 33 emergency doctors who participated in a prospective study of 1,134 patients at two teaching hospitals. The results appear in the July 13 online issue of the Annals of Emergency Medicine.
