Abstract
BACKGROUND AND AIMS: Naloxone is an opioid antagonist used for emergency resuscitation following opioid overdose. Prisoners with a history of heroin injection have a high risk of drug-related death soon after release from prison. The N-ALIVE pilot trial (ISRCTN34044390) tested feasibility measures for randomized provision of naloxone-on-release (NOR) to eligible prisoners in England. DESIGN: Parallel group randomized controlled pilot trial. SETTING: English prisons. PARTICIPANTS: A total of 1685 adult heroin injectors, incarcerated for at least 7 days pre-randomization, release due within 3 months and more than 6 months since previous N-ALIVE release. INTERVENTION: Using 1:1 minimization, prisoners were randomized to receive on-release a pack containing either a single 'rescue' injection of naloxone or a control pack with no syringe. MEASUREMENTS: Key feasibility outcomes were tested against prior expectations: on participation (14 English prisons; 2800 prisoners), consent (75% for randomization), returned prisoner self-questionnaires (RPSQs: 207), NOR-carriage (75% in first 4-weeks) and overdose-presence (80%). FINDINGS: Prisons (16) and prisoners (1685) were willing to participate (consent-rate, 95% CI: 70% to 74%); 218 RPSQs were received; NOR-carriage (95% CI: 63% to 79%) and overdose-presence (95% CI: 75% to 84%) were as expected. We randomized 842 to NOR, 843 to control during 30 months but stopped early because only one third of NOR administrations was to the ex-prisoner. Nine deaths within 12 weeks of release were registered for 1557 randomized participants released before 9 December 2014. CONCLUSION: Large randomized trials are feasible with prison populations. Provision of take-home emergency naloxone prior to prison release may be a life-saving interim measures to prevent heroin overdose deaths among ex-prisoners and the wider population.
