Remote Methadone Ingestion Surveillance Trial (RMIST)

Not Applicable

Completed

• Conditions: Opioid Use Disorder
• Interventions: Other: RMIST

• Registration Number: NCT05259501
• Lead Sponsor: University of Texas Southwestern Medical Center

Brief Summary

The Remote Methadone Ingestion Surveillance Trial (RMIST) will explore a potential method of methadone ingestion surveillance that may mitigate patient safety risks of take-home methadone treatment regimens while minimizing the risk of diversion and evaluating the acceptability and feasibility of these monitoring methods. The method utilizes an innovative existing technology.

Detailed Description

The Remote Methadone Ingestion Surveillance Trial (RMIST) aims to evaluate the performance and acceptability of a remote methadone ingestion surveillance that may mitigate the patient safety risks of take-home methadone treatment regimens for opioid use disorder (OUD) while minimizing the risk of diversion. Data describing the monitoring performance and patient acceptability of the method will inform investigators of the feasibility of using remote surveillance technology to monitor medication for OUD and mitigate treatment barriers. This study will lay the groundwork for a safe and robust remotely monitored methadone treatment platform that addresses long-standing accessibility and acceptability barriers to treatment for OUD.

Arm && Interventions

Group	Intervention	Description
Guided video recording with tamper-evident packaging	RMIST	This method uses automated visual recognition web-based platform and 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.

Primary Outcome Measures

Name	Time	Method
Methadone treatment adherence as measured by the number of time-stamped Medication Consumption Events (MCE) and Missed Detection Events (MDE).	Week 3	Methadone treatment adherence as measured by the number of time-stamped Medication Consumption Events (MCE) and Missed Detection Events (MDE). i. MCEs occur any time a participant has consumed medication as detected by the web-based monitoring platform video recording. i. MDEs occur whenever a participant misses a dose during the dosing window and whenever there are user errors or platform issues. MDEs will be grouped based on commonly documented issues (e.g., platform malfunction, participant error, participant nonadherence, etc.).
Platform usability as measured by number of and self-reported reasons for occasions participants need assistance.	Weeks 1-3	Number of occasions participants needed assistance from clinic or study staff to complete the remote monitoring process and self-reported reasons for accidental MDSs (Missed Detection Events).
