Measure
Guided Video Recording With Tamper-evident Packaging
This method uses automated visual recognition web-based platform and quick response (QR) tamper-evident labels to enhance the security of the take-home regimen currently used in methadone clinics. Single-use liquid methadone bottles are made tamper-evident through the application of a QR security label. RMIST: RMIST will involve: 1. A study automated visual recognition web-based platform accessible on the participant's smartphone web browser. 2. A supply of methadone in single use bottles and previously described packaging to be kept securely at the methadone clinic/lab setting.

OTHER_PRE_SPECIFIED outcome

Timeframe: Day 20

Measured by survey-based assessment designed to evaluate topics related to significant barriers to receiving opioid use disorder (OUD) treatments identified by the Substance Abuse and Mental Health Services Administration (SAMHSA) - acceptability and availability. 12 questions rated from Completely Disagree (0) to Completely Agree (4) with Completely Agree indicating perceived advantage. Highest advantage rating on this scale was 48; lowest 0.
