DescriptionWorkplace violence (WPV) is a complex and hazardous occupational problem healthcare workers face daily. The prevalence of WPV has increased exponentially in the healthcare industry in the past decade, specifically in outpatient mental health clinics. The increase is attributed to limited access to quality mental healthcare, poverty, substance abuse, and hereditary factors predisposing many individuals to mental health disorders. The purpose of this project is to determine the effect of WPV prevention training program and the use of violence risk assessment tools on the occurrence of patient-on-provider violence in outpatient mental health settings. Methodology: This project used a quasi-experimental design as the most suitable approach to assess the implementation of a violence risk assessment tool and WPV prevention training that targets incident of patient aggression. Results: Project results showed an increase in violence risk assessment post-implementation evidenced by a 53% increase in V-RISK-10 utilization. Also, there was a 36.4% decrease in patient-on-provider violent cases. Implications for practice: The result indicates an improved employees' workplace safety and violence prevention competency. It also provides a cost-effective way to manage type II violence.
