Workplace Violence in a Large Urban Emergency Department.

Importance: Workplace violence (WPV) against health care workers (HCWs) is common and likely underreported. Reliable data on the incidence of WPV and its impact on victims are lacking.

Objective: To prospectively define the frequency of WPV against HCWs in the emergency department (ED), examine whether HCW demographics are associated with increased risk, and explore the impact of these events on HCWs.
