Introduction Hospital-based violence intervention programmes (HBVIPs) are a promising strategy to reduce trauma recidivism and promote safety among victims of violent injury. While previous studies have demonstrated cost-effectiveness and positive impact on the lives of victims, there are a number of key limitations in the study designs of this evidence base. This study seeks to address the methodological shortcomings of previous research, determine the efficacy of HBVIPs using a randomised control study design, and provide a better understanding of successful service allocation within an HBVIP.

Methods and analysis The current study is 1 of 12 demonstration projects being implemented around the country with the purpose of bolstering the ability to provide effective, culturally appropriate and trauma-informed services for boys and men harmed by violence. We propose a randomised control trial in which male victims of violence receive one of two interventions: treatment as usual versus enhanced services. The purpose is to determine which intervention leads to reductions in trauma recidivism over the period of 1 year from contact with the programme. Differences will also be monitored on measures of mental health, quality of life and attitudes towards violence. Analyses employed will include Kaplan-Meier analysis and Cox proportional hazards regression with death and recidivism being the outcomes of interest.

Ethics and dissemination Study procedures have been approved by the Institutional Review Boards of the University at Buffalo and four hospitals. Results will be submitted for publication in peer-reviewed journals.
