Engaging Emergency Department clinicians in identifying fears and challenges about safety will support a more secure environment. Identifying staff perceptions regarding safety guided intervention development to maximize security. A survey identified staff perceptions of security, and was repeated after the implementation of mitigation interventions in a New Hampshire community hospital Emergency Department. Staff members, Security Officers, and Patient Registrars were invited to participate in anonymous online surveys pre- and post- mitigation intervention implementation. Data were analyzed for significant differences in responses pre- and post- interventions. Following the initial survey, interventions addressing staff concerns were developed and implemented. In the post-intervention survey, significant differences were noted in 5 of 11 staff concerns. Staff security is a moving target in this environment. Leaders must look at the team as a whole. Interventions designed will drive ongoing educational initiatives, policy revision, and clarification of responsibilities among team members in order to improve safety.
