Safety
Statistical methods / analysis
As a phase II/III trial designed to assess safety and feasibility in a unique setting, sufficient numbers of participants at each site are required to assess safety in a range of correctional centre types and inmate populations. Sufficient numbers per site are also required to obtain meaningful information about service impacts. To ensure sufficient data is collected for safety analysis participants who do not complete the protocol will be replaced.

Summary
Brief summary
This four-month trial will compare long-acting depot buprenorphine (CAM2038) to standard of care (oral methadone) in adult males and females in custody with opioid use disorder to identify any unexpected safety and tolerability considerations specific to the adult custodial population in NSW.

Analysis of routinely collected data will examine clinic-based diversion (or attempted diversion) among all inmates receiving opioid agonist therapy (depot buprenorphine, sublingual buprenorphine- naloxone film and oral methadone) as well as violent misconduct and involvement in assaults at each site and among trial participants. Further, a cost-consequence study will be undertaken to compare the costs and consequences of dosing activity recorded for all treatment types for both JH&FMHN clinical practice and CSNSW officer time. Finally, focus groups with CSNSW and JH&FMHN staff will be conducted to assess staff satisfaction and acceptability of OAT and related issues.
