Long-term Evaluation of a Hospital-Based Violence Intervention Program using a Regional Health Information Exchange.

Background: Hospital-based violence intervention programs (HVIP) aim to reduce violent-injury recidivism by providing intensive, case management services to high-risk patients who were violently injured. Although HVIP have been found effective at reducing recidivism, few studies have sought to identity how long their effects last. Additionally, prior studies have been limited by the fact that HVIP typically rely on self-report or data within their own healthcare system to identify new injuries. Our aim was to quantify the long-term recidivism rate of participants in an HVIP program using more objective and comprehensive data from a regional health information exchange (HIE). Methods: The study included 328 patients enrolled in Prescription for Hope (RxH), an HVIP, between January 2009 and August 2016. We obtained RxH participants' emergency department (ED) encounter data from a regional HIE database from the date of hospital discharge to February 2017. Our primary outcome was violent-injury recidivism rate of the RxH program. We also examined reasons for ED visits that were unrelated to violent injury. Results: We calculated a 4.4% recidivism rate based on 8 years of statewide data, containing 1,575 unique encounters. Over 96% of participants were matched in the state database. Of the 15 patients who recidivated, only 5 were admitted for their injury. Over half of new violence-related injuries were treated outside of the HVIP-affiliated trauma center. The most common reasons for ED visits were pain (718 encounters), followed by suspected complications or needing additional postoperative care (181 encounters). Substance abuse, unintentional injuries, and suicidal ideation were also frequent reasons for ED visits. Conclusion: The low, long-term recidivism rate for RxH indicates that HVIP have enduring positive effects on the majority of participants. Our results suggest HVIP may further benefit patients by partnering with organizations that work to prevent suicide, substance use disorders, and other unintentional injuries.
