BACKGROUND High overdose mortality after release from state prison systems is well documented; however, little is known about overdose mortality following release from local criminal justice systems (CJS). The purpose of this study was to assess overdose mortality following release from a local CJS in Philadelphia, PA. METHODS We conducted a retrospective cohort study of individuals released to the community from a local CJS between 2010 and 2016. Incarceration records were linked to overdose fatality data from the Medical Examiner's Office and death certificate records. All-cause, overdose, and non-overdose mortality were examined. RESULTS Of the 82,780 individuals released between 2010 and 2016, 2,522 (3%) died from any cause, of which 837 (33%) succumbed to overdose. Individuals released from incarceration had higher risk of overdose death compared to the non-incarcerated population (Standardized Mortality Ratio [SMR]: 5.29, 95% CI 4.93-5.65), and risk was greatest during the first two weeks following release (SMR: 36.91, 95% CI: 29.92-43.90). Among released individuals, black, non-Hispanic individuals (Hazard Rate [HR]: 0.17, 95% CI: 0.14-0.19) and Hispanic individuals (HR: 0.41, 95% CI: 0.34-0.50) were at lower risk for overdose than white, non-Hispanic individuals. Individuals released with a serious mental illness (SMI) were at higher risk of overdose (HR: 1.54, 95% CI: 1.27-1.87) than those without a SMI. DISCUSSION Previously incarcerated individuals are at high risk of overdose death following release from a local CJS, especially in the earliest weeks following release. Prevention measures including behavioral health treatment and referral and take-home naloxone may reduce overdose mortality after release.
