Though active shooter events are rare, it is practical and necessary to be well-prepared for the possibility, especially when you work with the public. Between 2010 and 2020, The Joint Commission (TJC) received 39 reports of active shootings that resulted in 39 deaths at accredited hospitals (TJC, 2021). As a result, the Center for Medicare Services (CMS) and TJC require hospitals to prepare for all hazards, including active shooter or hostage events, and to work with their local law enforcement and emergency response agencies to prepare for and respond to active shooter events. Understanding the risks and motivations behind active shooter events, how your body and mind may respond to stress, and how best to prepare for an active shooter event is the best way to protect yourself and others should the unthinkable occur in your facility.
