Workload, Usability, and Engagement with a Mobile App Supporting Video Observation of Methadone Take-Home Dosing: Usability Study

BACKGROUND

Methadone, a cornerstone of opioid use disorder treatments for many decades, is an essential tool for combatting the opioid epidemic. However, requirements for observing methadone dosing in person through direct observed therapy (DOT) impose significant barriers for many patients. Digital technology can facilitate remote DOT, which could reduce barriers to methadone treatment. Currently, there are limited data on the usability of such technology among patients and counselors in methadone treatment settings.

OBJECTIVE

The primary objective of this study was to assess the workload, usability, and engagement of a video-based DOT mobile app for patients with opioid use disorder receiving methadone treatment. The secondary objective was to assess the workload, usability, and engagement of the provider-facing app portal used by counselors.

METHODS

Patients (n=12) and counselors (n=3) who previously tried video DOT for methadone through a smartphone app in an opioid treatment program participated in usability testing sessions. Participants completed essential tasks for video DOT, then provided ratings of workload (NASA Task Load Index), usability (modified System Usability Scale), and engagement (modified Engagement Scale) with the core features of the video DOT program.

RESULTS

Patients and counselors reported low mental, physical, and temporal demands, successful performance, low effort, and low frustration associated with activities. Patients reported high usability (mean 85, SD 9.5) and engagement (mean 3.8, SD 1.1); counselors reported moderate usability (mean 43.3, SD 17.7) and engagement (mean 2.81, SD 0.63).

CONCLUSIONS

A mobile health app that facilitates video-based DOT for methadone required a low workload for patients and counselors and was highly usable for patients in an opioid treatment program; however, there are opportunities to improve usability and engagement for the counselor-facing portal.

"Sign Me Up": a qualitative study of video observed therapy (VOT) for patients receiving expedited methadone take-homes during the COVID-19 pandemic

BACKGROUND

Federal and state regulations require frequent direct observation of methadone ingestion at an Opioid Treatment Program (OTP)-a requirement that creates barriers to patient access. Video observed therapy (VOT) may help to address public health and safety concerns of providing take-home medications while simultaneously reducing barriers to treatment access and long-term retention. Evaluating user experiences with VOT is important for understanding the acceptability of this strategy.

METHODS

We conducted a qualitative evaluation of a clinical pilot program of VOT via smartphone that was rapidly implemented between April and August 2020 during the COVID-19 pandemic within three opioid treatment programs. In the program, selected patients submitted video recordings of themselves ingesting methadone take-home doses, which were asynchronously reviewed by their counselor. We recruited participating patients and counselors for semi-structured, individual interviews to explore their VOT experiences after program completion. Interviews were audio recorded and transcribed. Transcripts were analyzed using thematic analysis to identify key factors influencing acceptability and the effect of VOT on the treatment experience.

RESULTS

We interviewed 12 of the 60 patients who participated in the clinical pilot and 3 of the 5 counselors. Overall, patients were enthusiastic about VOT, noting multiple benefits over traditional treatment experiences, including avoiding frequent travel to the clinic. Some noted how this allowed them to better meet recovery goals by avoiding a potentially triggering environment. Most appreciated having increased time to devote to other life priorities, including maintaining consistent employment. Participants described how VOT increased their autonomy, allowed them to keep treatment private, and normalized treatment to align with other medications that do not require in-person dosing. Participants did not describe major usability issues or privacy concerns with submitting videos. Some participants reported feeling disconnected from counselors while others felt more connected. Counselors felt some discomfort in their new role confirming medication ingestion but saw VOT as a useful tool for select patients.

CONCLUSIONS

VOT may be an acceptable tool to achieve equipoise between lowering barriers to treatment with methadone and protecting the health and safety of patients and their communities.

Acceptability, feasibility, and outcomes of a clinical pilot program for video observation of methadone take-home dosing during the COVID-19 pandemic

BACKGROUND

Methadone is one of the most utilized treatments for opioid use disorder. However, requirements for observing methadone dosing can impose barriers to patients and increase risk for respiratory illness transmission (e.g., COVID-19). Video observation of methadone dosing at home could allow opioid treatment programs (OTPs) to offer more take-home doses while ensuring patient safety through remote observation of ingestion.

METHODS

Between April and August 2020, a clinical pilot program of video observation of methadone take-home dosing via smartphone was conducted within a multisite OTP agency. Participating patients completed a COVID-19 symptom screener and submitted video recordings of themselves ingesting all methadone take-home doses. Patients who followed these procedures for a two-week trial period could continue participating in the full pilot program and potentially receive more take-home doses. This retrospective observational study characterizes patient engagement and compares clinical outcomes with matched controls.

RESULTS

Of 44 patients who initiated the two-week trial, 33 (75 %) were successful and continued participating in the full pilot program. Twenty full pilot participants (61 %) received increased take-home doses. Full pilot participants had more days with observed dosing over a 60-day period than matched controls (mean = 53.2 vs. 16.6 days, respectively). Clinical outcomes were similar between pilot participants and matched controls.

CONCLUSIONS

Video observation of methadone take-home dosing implemented during the COVID-19 pandemic was feasible. This model has the potential to enhance safety by increasing rates of observed methadone dosing and reducing infection risks and barriers associated with relying solely on face-to-face observation of methadone dosing.

Mortality in an Opioid Treatment Program

This retrospective study examined mortality in an Opioid Treatment Program (OTP) with policies designed to admit and retain patients with as few barriers as possible. Methadone provided in the context of an OTP is known to decrease mortality and morbidity. Historically, patients have been discharged or turned away because of continued substance use. We examined patient deaths over three years in an OTP serving approximately 2400 patients daily. Demographics and causes of death were gathered from electronic health records and medical examiner reports. Pairwise comparisons were used to compare drug poisoning versus non-drug poisoning deaths. There were 155 deaths during the study period. The average age was 54, and half of the participants had positive results on their most recent drug screen. Forty one (26%) died from "drug poisoning." Drug poisoning deaths were more common among patients who: 1) had recent positive drug test results; 2) had documented alprazolam use; 3) were younger; 4) had shorter treatment durations; 5) were female. The majority of deaths were among long-term patients over 50 and were not caused by drug poisoning. These results support keeping patients in treatment despite ongoing drug use, and linking them to appropriate primary care.

Re-thinking patient stability for methadone in opioid treatment programs during a global pandemic: Provider perspectives

COVID-19 necessitated rapid changes in methadone take-home policies in opioid treatment programs (OTPs); these changes markedly contrast with existing, long-standing federal mandates on OTP rules about take-home methadone. OTP providers describe how these changes have affected clinical decision-making, equity in patient care, and workflow. We also discuss implications for medical ethics and patient autonomy. We provide suggestions for future research that will examine the impact of COVID-19 on OTP treatment and its patients, as well as the effect of making methadone take-home polices patient centered, all of which may foreshadow larger changes in the ways OTPs deliver their services.
