  TPI Outcomes

TPI Community Outcome Indicators

Community outcome indicators, including trauma hospital visits and violent crime rates, are used to estimate impact of TPI strategies, using the year prior to implementation of each strategy as baseline. While TPI overall began in 2015, HBVI implementation started in July 2017, and Street Outreach in June-July 2018.

Trauma Hospital Visits

TPI receives annual data from the LA County Emergency Medical Services Agency that includes assault-related trauma hospital visits. Trauma visits include severe injuries that are transported to hospitals with a trauma center designation, where individuals receive specialized care for violence related injuries, including shootings, stabbings, and blunt force. Between 2016 and 2017, the first year that HBVI was implemented, TPI communities saw an 18% reduction in assault-related trauma hospital visits, compared to a 12% reduction in LA County Overall; and reduced their burden of countywide assault-related trauma hospital visits from 13% to 12%.

Crime Trends

TPI receives monthly crime data from the Los Angeles County Sheriff’s Department. This includes Part I serious and violent crimes: aggravated assault, arson, burglary, criminal homicide, forcible rape, grand theft auto, larceny theft and robbery. Sheriff’s Department also includes a variable to identify crimes as “gang-related” however it is not clear how consistently it is defined and reported. Overall among the four communities, violent crimes peaked from 2016 to 2017, the first year of HBVI implementation, and the year before Street Outreach implementation. Between 2016 and 2019, violent crimes in 3 communities declined, while Unincorporated Compton increased slightly, showing promising early results for implementation of these strategies
