Law enforcement-led, pre-arrest diversion-to-treatment may reduce crime recidivism, incarceration, and overdose deaths: Program evaluation outcomes.

Introduction: Substance use disorder (SUD), overdose, and drug use-related crime continue to increase in the U.S. Pre-arrest diversion-to-treatment programs may decrease crime recidivism and overdose deaths. We assessed the impact of a community-wide diversion-to-treatment initiative on crime, incarceration, and overdose. Methods: This article reports on the prospective evaluation of a law enforcement-led, pre-arrest diversion-to-treatment program on crime, incarceration, and overdose deaths compared between participants who did not engage (Non-Engaged; n=103), engaged but did not complete (Non-Completers; n=60) and completed (Completers; n=100) the program. Participants included 263 adults apprehended by police officers for low-level, drug use-related crimes between September 1, 2017 and August 31, 2020. The program offered eligible persons participation in a six-month program consisting of a clinical assessment, referral to addiction treatment services based on each individual’s needs, connection to recovery peer support, and treatment engagement monitoring. Completers had their initial criminal charges ‘voided,’ while Non-Engaged and Non-Completer participants had their original charges filed with local prosecutors. The project collected participant-level data on arrests and incarceration within 12 months before and 12 months after program enrollment and data on fatal overdose within 12 months after program enrollment. Logistic regression predicted outcomes using baseline demographics (sex, age, race, housing status) and pre-index crime arrest and incarceration indices as covariates. Results: After accounting for baseline demographics and pre-enrollment arrest/incarceration history, logistic regression models found that the Non-Engaged and the Non-Completer groups were more likely than Completers to be arrested (odds ratios [ORs]: 3.9 [95% CI, 2.0-7.7] and 3.6 [95% CI, 1.7-7.5], respectively) and incarcerated (ORs: 10.3 [95% CI, 5.0-20.8] and 21.0 [95% CI, 7.9-55.7], respectively) during the 12-month follow-up. Rates of overdose deaths during the 12-month follow-up were greatest in Non-Engaged (6/103, 5.8%) and Non-Completer (2/60, 3.3%) groups; Completers had the lowest rate (2/100, 2.0%), with all deaths occurring after completion of the six-month treatment/monitoring program. Conclusions: Collaboration between law enforcement, clinicians, researchers, and the broader community to divert adults who commit a low-level, drug use-related crime from criminal prosecution to addiction treatment may effectively reduce crime recidivism, incarceration, and overdose deaths.
