Technology-assisted methadone take-home dosing for dispensing methadone to persons with opioid use disorder during...

Covid-19 confers substantial risk for the >400,000 patients who receive methadone for the treatment of opioid use disorder (OUD) and methods for safely dispensing large quantities of methadone to patients are lacking.

This study evaluated the MedMinder "Jon", an electronic and cellular-enabled pillbox that provides real-time monitoring to remotely manage take-home doses of methadone using a 12-week, within-subject, Phase II (NCT03254043) trial. We transitioned all participants from liquid to tablet methadone one week prior to randomization. Participants completed both treatment-as-usual and electronic pillbox conditions before choosing a condition in a final "choice phase". We assessed feasibility, satisfaction, and safety outcomes during the exit interview.

Overall, we randomized 25 participants, 24 (96.0%) completed >1 study session, and 21 (84.0%) completed the exit interview. We dispensed 167.92 g (1,974 doses) of methadone. Participants would use the pillbox again (86.3%) and recommend it to others (95.4%). Overall, 52.4% selected the pillbox in the choice condition and those who did not cited issues related to study requirements. Less than 1% of pillbox alerts were for medication being consumed outside the dosing window and we observed no evidence of actual or attempted methadone diversion.

We were able to adequately manage patients who would not otherwise qualify for large quantities of take-home methadone when we dispensed methadone tablets via a secure pillbox. The integration of a commercially available pillbox into routine clinic operations increases opportunity for dispensing medication. Our data support remote monitoring of methadone take-home doses and may inform clinic practices related to Covid-19.
