Hospital shootings are rare but challenging. Most perpetrators are determined, and many incidents occur outside the building, posing security risks.
Area of Science:
- Public Health
- Criminology
- Healthcare Security
Background:
- Workplace violence is prevalent in healthcare settings.
- Emergency departments (EDs) are particularly vulnerable to violence.
- Data on hospital-based shootings are limited.
Purpose of the Study:
- To characterize US hospital-based shootings between 2000 and 2011.
- To analyze the nature and circumstances of these events.
- To identify trends and contributing factors.
Main Methods:
- Searched LexisNexis, Google, Netscape, PubMed, and ScienceDirect for hospital shooting events.
- Included acute care hospitals in the United States from 2000 to 2011.
- Analyzed all events with at least one injured victim.
Main Results:
- Identified 154 hospital-related shootings, with 235 injured or dead victims.
- The majority of perpetrators were men; common motives included grudge, suicide, and prisoner escape.
- Emergency departments were frequent sites, with perpetrators sometimes using security officers' weapons; perpetrator was the most common victim.
Conclusions:
- Hospital shootings are relatively rare compared to other workplace violence.
- The unpredictable nature and determined perpetrators present significant security challenges.
- Many shootings occur outside the hospital, complicating deterrence efforts.
