This study evaluates emergency physicians' perceptions of the malpractice risk posed by utilization of physician assistants (PAs) in emergency departments (EDs) in 2004 and again in 2009. ⋯ As physicians gain clinical experience with PAs, their perceived risk of malpractice tends to decrease. These results may have implications for the utilization of PAs, particularly as EDs become more utilized for noncritical situations.
