When it was established in 2019, the Violence Prevention Unit commissioned a new nurse-led intervention at the University Hospital of Wales, with the understanding that Emergency Departments have a unique opportunity to intervene early, and prevent victims of violence from being hurt again. The evaluation of the Violence Prevention Team explores the development and implementation of the service within the Emergency Department, and the nature and level of support provided to patients with violence-related injury. The evaluation included interviews with clinical staff and other professionals, for example, police, as well as analysis of service data.
