About

The goal of this clinical trial is to determine the effects of an app to reduce opioid and cocaine use when layered atop methadone treatment as usual among people using both opioids and cocaine. The main questions it aims to answer are:

  • Do people who use the app remain in methadone treatment longer than people who receive only treatment as usual?
  • Do people who use the app report using opioids and/or cocaine less often, and do they report better improvements in their quality of life, than people who receive only treatment as usual?
  • Does using the app more lead to better methadone treatment outcomes among people using the app?

Participants in this study will be randomly assigned to receive either the app or methadone treatment as usual. Participants randomly assigned to the treatment as usual group will receive access to methadone services as normally provided, including scheduled access to medications, information about the consequences of opioid and other drug use, and any onsite services (including group based interventions and/or 12-step programs). Those randomized into the app-using group will receive all the same services as the treatment as usual group, but will also be given a phone with the app already installed, or will have the app installed on their existing phone if they already have one. At random times throughout the week, the app will ask participants to submit drug tests for opioids and cocaine, which participants will be able to do remotely without having to physically "go to" a testing site. For each test that demonstrates the participant hasn't used opioids or cocaine, the participant will be rewarded with money directly into a debit card. Participants will also be able to earn rewards for picking up treatment-related medications, attending onsite appointments, and other treatment-related activities.

Full description

This two-arm randomized trial will evaluate the impact of 48 weeks of the DynamiCare app-based CM (DCM) intervention on retention in methadone treatment and polysubstance use among 240 methadone maintenance (OTP) patients with comorbid opioid use disorder and cocaine use disorder. New enrollees in methadone maintenance at two community treatment programs will be randomly assigned to either methadone treatment-as-usual (TAU) at the OTP or methadone TAU paired with the DynamiCare Health app (TAU+DCM) including remote drug testing and monetary rewards for negative opioid and cocaine tests indicating abstinence. Data on methadone treatment retention will be obtained through OTP records, and follow-up assessments will be conducted at 3-, 6-, and 12-months post-enrollment.

The study will examine participant outcomes in the domains of three aims:

Aim 1: To determine the relative effectiveness of TAU+DCM compared to TAU alone in improving methadone treatment retention through 12-months post treatment entry.

Aim 2: To determine the relative effectiveness of TAU+DCM compared to TAU alone in terms of [AIM 2a] reducing opioid use and cocaine use; and [Aim 2b] improving other secondary outcomes including non-targeted substance use and quality of life through 12-months post treatment entry.

Aim 3: To explore app use patterns, acceptability, and perceived value of personalized content on opioid and polysubstance use through 12-months post treatment entry.

240 participants in 2 patient groups

Methadone Treatment-as-Usual
Active Comparator group
Description:
Participants randomized to the Methadone Treatment-as-Usual (TAU) Condition will receive treatment-as-usual at the community methadone clinics, which will include daily medication, individual and group addiction counseling, and outpatient or intensive outpatient behavioral health services, depending on the clinic and the needs of the patient. After randomization into the TAU arm, participants will complete the program's psychosocial and medical intake, methadone dose induction and adjustment, and provide urine tests and receive medication take-homes per the program's policies and methadone treatment regulations.
Treatment:
Drug: Methadone Treatment-As-Usual
DynamiCare Plus Methadone Treatment-as-Usual
Experimental group
Description:
DynamiCare Plus Methadone Treatment-as-Usual (DCM+TAU) participants will receive the same services as TAU participants, plus access to the DynamiCare Health smartphone app for 48 weeks. After randomization, the research assistant (RA) will download the DynamiCare Health app onto their smart phone (or provide them with a smartphone with the app already installed). Participants will get oral fluid testing kits and a Next Step debit card. Participants will be trained in use of the app and oral fluid test kits and will practice until they can produce two valid tests in a row without aid of the research staff. Participants will earn $40 for successful completion of the orientation and training. DCM+TAU participants will then use the app to complete remote random drug screenings, prove attendance to appointments and medication pickups, interact with modules designed to improve substance use reductions, and other treatment-related activities.
