Emergency health service contact and reincarceration after release from prison: A prospective cohort study.

BACKGROUND: Adults released from prison often have complex health needs. They are at high risk of poor health outcomes and reincarceration, with health service use unlikely to be planned.

AIMS/HYPOTHESES: To determine the incidence of emergency health service (EHS) use, ambulance attendance and/or emergency department presentation, among 1,181 adults released from Australian prisons. We hypothesised that EHS contact would be associated with increased reincarceration risk.

METHODS: Baseline surveys were conducted within 6 weeks before release. Postrelease EHS contacts and reincarceration were identified through prospective data linkage. For each participant, EHS contacts within a 24-hour period were combined to make an episode. We used Cox proportional hazards regression to examine the relationship between EHS episodes and reincarceration, controlling for covariates.

RESULTS: More than half (53.3%) of participants had at least one EHS contact over a median of 25.6-month follow-up. In adjusted analyses, compared to those with no EHS contacts, the hazard of reincarceration was greater for participants who had one to three EHS episodes (hazard ratio [HR] = 1.84; 95% confidence interval [CI] [1.48, 2.29]) or four or more (HR = 2.35; 95% CI [1.67, 3.29]).

CONCLUSIONS/IMPLICATIONS FOR PRACTICE: Emergency department attendance by people with a history of imprisonment may be indicative of wider decompensation. Improved management of such patients may improve health outcomes and have collateral benefits for reducing reincarceration.
