Initiating buprenorphine treatment prior to versus after release from prison: Arrest outcomes.

BACKGROUND

This secondary analysis of a randomized trial examines the association between initiation of buprenorphine treatment prior to, versus post-release, and rearrests during the 12-months following release.

METHODS

Official rearrest data (N = 199) for the 12-months post-release were examined. Four outcomes were measured: (1) rearrested (yes/no), (2) time to rearrest, (3) number of rearrests, and (4) severity of charges (less severe vs. severe).

RESULTS

A minority (43.1%) of the sample were rearrested (N = 91). There were no significant differences between study conditions in the proportion of rearrested participants [P = 0.28] nor in the mean number of arrests [P  = 0.15]. Likewise, the condition was not a significant predictor of the hazard of rearrest [p = 0.10]. The mean number of days until rearrest for the in prison vs. post-release buprenorphine conditions were not significantly different (205.8 days (SD  = 104.6) vs. 170.8 days (SD  = 113.1), respectively; P  = 0.13]. Treatment condition was not a significant predictor of the likelihood of rearrest for a severe crime compared to a less severe crime [P  = 0.09].

CONCLUSION

Despite the parent study finding of higher rates of post-release drug treatment entry in the group assigned to start buprenorphine treatment prior to, compared to post-release, there were no significant differences in the proportion of individuals arrested, the mean number of arrests, the time to first arrest, or the severity of their charges.
