Hospital police are specialized police agencies in the United States that provide law enforcement services and security to hospitals. As a result of the increase violence in the healthcare field, mental health patients, and a wide range of civil disturbances found across the nation, hospital security often proved insufficient. This occasionally resulted in injury to both the hospital staff and the security officers. These hospital security officers were often poorly trained, ineffectively led, and unprepared to respond to these turbulent and unanticipated events. Trauma centers treat patients of assaults, stabbings, and shootings which brings upset family and friends. Hospitals have the potential for violence on a daily basis.
