Non-fatal drug overdose after release from prison: A prospective data linkage study

Area of Science:

• Public Health
• Criminology
• Addiction Medicine

Background:

• Individuals transitioning from incarceration are at elevated risk for adverse health outcomes, including overdose.
• Non-fatal overdose (NFOD) is a significant predictor of subsequent fatal overdose and contributes to substantial morbidity.

Purpose of the Study:

• To determine the incidence of NFOD among adults recently released from prison.
• To identify demographic, health, social, and criminal justice predictors of NFOD post-release.

Main Methods:

• Utilized pre-release interview data from a randomized controlled trial (2008-2010).
• Linked data with state-wide ambulance, emergency department, and hospital records for 1307 adults in Queensland, Australia.
• Employed a multivariate Andersen-Gill model to analyze predictors of NFOD.

Main Results:

• The crude incidence rate of NFOD was 47.6 per 1000 person-years, peaking in the first 14 days post-release (296 per 1000 person-years).
• Predictors of NFOD included recent substance use disorder (SUD), dual diagnosis, history of injecting drug use, prior NFOD, benzodiazepine dispensing, shorter incarceration, and low perceived social support.
• High-risk alcohol use and incarceration were associated with a lower risk of NFOD.

Conclusions:

• Adults released from prison are at high risk for NFOD, with the greatest danger in the initial two weeks.
• Coordinated transitional care bridging prison and community settings is crucial for mitigating overdose risk.
