Home-based delivery of XR-NTX in youth with opioid addiction.

Early experience with relapse prevention medications in the treatment of opioid addiction in youth has been positive, but barriers to effectiveness and broader adoption have included problems with adherence and retention, and lack of evidence or consensus about implementation. In particular there is relatively little known about either the effectiveness of extended release naltrexone (XR-NTX) in youth, or optimal models of care for its delivery. The purpose of this study is to report on a pilot initiative to improve the effectiveness of XR-NTX by delivering doses at home with assertive outreach to patients enrolled in a community treatment outpatient program. This is a naturalistic case series based on retrospective chart abstractions of 14 young adults (mean age=20.5), who enrolled in the pilot program, and in particular, the 9 who received home-based doses of XR-NTX. They are compared to a historical group of patients (n=21) prior to the pilot, who were referred to receive standard clinic-based doses of XR-NTX. Home-based administration was viewed favorably by patients and families. Although the small sample size is not amenable to statistical analysis, patients in the home based group, compared to the historical clinic-based group, received a greater number of doses overall and over 16 weeks of treatment, had longer retention, and attended similar numbers of clinic-based counseling sessions. These preliminary findings suggest that home-based delivery of XR-NTX and assertive outreach are feasible and promising in this critical target population, may compare favorably to clinic-based treatment as usual, and should be explored further in more rigorous evaluations.
