The purpose of this study was to compare the occurrences of coercive interventions and violence-related staff injuries before and after a 2-year violence prevention intervention on a psychiatric intensive care unit. The intervention aimed to improve nursing care by addressing patient violence from multiple perspectives. During the study, the unit was reorganized toward a higher concentration of severely disturbed patients. The results showed an increased proportion of coercive interventions without a corresponding increase in staff injuries. Use of coercive interventions is discussed in relation to a safe environment for both patients and staff.
