TPI has three main objectives: 1) reduce violent crime and assault-related trauma center visit rates in communities disproportionately impacted by violence through intervention strategies, 2) increase the capacity of grassroots organizations to prevent violence through training and technical assistance, and 3) build community engagement and cross sector collaboration by investing in prevention infrastructure and community identified strategies.
Significant achievements have been demonstrated in the early years of implementation in each of these 3 areas. The first 5 years of TPI implementation demonstrates promising results for decreases in violent crime and for building sustainable infrastructure for violence prevention and intervention in LA County unincorporated communities.
TPI evaluation efforts include process and outcome assessment and indicators to measure the impact of each objective including the reduction in assault related trauma center visits and violent crimes, community engagement, community capacity building, cross sector collaboration, and perceptions of safety. Public Health staff collect and analyze process and outcome data for the initiative and conduct analysis of community-level rates and trends over time. TPI also works with intervention funded agencies to develop data collection protocols, conduct the evaluation of HVI and Street Outreach strategies, and conduct door-to-door community safety surveys. Overall, 2015 is regarded as the baseline year for the TPI evaluation, however, each strategy began implementation in different years and trends are examined accordingly.
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, HVI implementation started in July 2017, and Street Outreach in June/July 2018. For trauma hospital visits, staff receive annual data from the LA County Emergency Medical Services Agency that includes assaultrelated 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.
TPI staff also receive monthly crime data from the Los Angeles County Sheriff’s Department (LASD). This includes Part I serious and violent crimes: aggravated assault, arson, burglary, criminal homicide, forcible rape, grand theft auto, larceny theft and robbery. LASD also includes a variable to identify crimes as “gang-related” however it is not clear how consistently it is defined and reported. In 2015, Urban Peace Institute (UPI) conducted a Community Safety Survey in three TPI communities, collecting a total of 312 surveys primarily in the Watts-Willowbrook community (74%) and including a limited sample in Westmont West Athens and Florence Firestone. In 2018, a follow up survey was conducted in all four TPI communities, and a total of 1,785 surveys were collected with the addition of unincorporated Compton. UPI used a unique approach to conduct the survey, hiring community intervention workers who are regarded as credible messengers, to go door-to-door and gather perceptions about civic engagement, access to services, main community issues and priorities, and the roles of groups and agencies in improving community safety. Results of the survey were used to gauge the impact of TPI strategies on perception of safety and gather insights and recommendations to guide the work of TPI and county and community partners.
TPI staff work closely with community stakeholders to provide backbone support for ongoing community engagement, determining how to best support existing leadership networks and coalitions in each community. After extensive relationship building and research, TPI staff supported stakeholders to establish Community Action for Peace (CAP) groups in Westmont West Athens and Willowbrook. CAPs meet at least once each month to develop community-driven strategies for violence prevention within their community. CAPs provide a space for community members to meet, discuss and identify community issues relating to violence and to work together to create programs, events, and trainings that respond to immediate concerns. TPI staff are actively working to develop and strengthen relationships with community leaders and stakeholders in Florence/Firestone and unincorporated Compton to establish CAP groups in these communities as well. TPI contracts with community-based organizations to provide facilitation and strategic planning and leadership capacity building support for CAPs. Early work with CAPs mobilized stakeholders around convening community summits to foster collaboration and positive identify and later work transitioned to more focused capacity and leadership building.
Last, TPI has hosted quarterly Advisory Committee meetings since 2016 for a multi-sector group of county departments and initiative representatives, and TPI funded partners, to guide the initiative and identify opportunities for systems change. The Committee includes nearly 200 members from 70 different organizations. TPI staff update committee members on the progress of each strategy, facilitate discussions of successes and challenges of the work, and provide space for community organizations to present their work and to connect with county providers.
Summary of Impacts
-Since 2017 TPI has contracted with Southern California Crossroads to implement Hospital Based Violence Intervention (HVI). TPI has contracted with agencies to provide Street Outreach and Community Violence Intervention Services in 4 communities since 2018.
-TPI has established protocols for gang intervention services in unincorporated communities, with clear roles, responsibilities, and guidelines for Street Outreach team members to work with Parks and Recreation for safe passages, and with the Sheriff’s Department for incident response.
-Between 2015-2018, year two of HVI implementation, TPI communities saw a 37% reduction in assault-related trauma hospital visit rates, compared to a 21% reduction in LA County overall.
-During 2020, Crossroads provided HVI case management to 175 clients out of 460 referrals at St. Francis and Harbor UCLA Medical Centers.
-During 2020, Street Outreach agencies conducted more than 4000 activities including safe passages at parks and schools (33%), community meetings and relationship building (16%), client engagement (10%), and conflict resolution (6%). Agencies responded to a total of 119 incidents including 29 homicides.
-In 2020 during the COVID-19 pandemic, Street Outreach workers were lifelines for some of the county’s hardest hit communities, addressing food insecurity, COVID safety and education, while still addressing existing community violence.
-Through December 2020, TPI provided technical assistance to over 100 community-based organizations.
Based on early data and data analysis, TPI has saved the County an estimated $1,977,395 per year in criminal justice costs between the baseline year of 2016 and 2019, based on analysis of decreased aggravated assaults in TPI communities compared to Sheriff’s Department communities overall. Compared to LASD overall, there was no significant decrease in other types of violent crime in TPI communities during this time period. TPI is continuing to assess the impact of COVID-19 on community violence. While overall violent crimes in TPI communities declined between 2016 and 2020, there were no significant decreases in aggravated assaults or homicides in TPI communities relative to Sheriff’s Department communities overall.
2016 – 2019 aggravated assaults:
TPI communities: decreased from 947 to 846 (10.7% decrease)
Sheriff’s Department overall: decreased from 6983 to 6745 (3.4% decrease)
If TPI communities had experienced just a 3.4% decrease they would have expected 914 assaults in 2019.
Difference between actual (846) and expected assaults (914) = 68
RAND study average cost per serious assault = $87,238
Estimated savings for reduction in violence in TPI communities compared to reduction in LASD overall:
$87,238 * 68 = $5,932,184 / 3 years = $1,977,395 per year
TPI achievements are the result of partnerships with community members, non-profit and faith-based organizations, and with county departments. The comprehensive, community-driven model built by TPI has served as an incubator for new ideas and for advancing systems change. This preliminary work has also revealed many challenges and lessons learned to inform future work and proposed TPI expansion. TPI’s approach and strategies provide an initial foundation for building a comprehensive, countywide, community-driven violence prevention approach tailored to the unique needs of communities.
