About the trial
What the trial wants to find out
This is the third phase of the mPeer4Life study - the Trial Phase, will be evaluating the intervention that was developed based on the Formative and Pilot Phases. The study population are patients transitioning from the Emergency Department (ED) or hospital to outpatient Medication Assisted Treatment (MAT). The RCT will consist of three arms (1:1:1) with 30 participants in each arm:

* Arm 1 will include a peer navigator + mobile phone-assisted intervention * Arm 2 will have a peer navigator only * Arm 3 will follow the standard of care referral for MAT linkage All patient-level participants will complete baseline and exit interviews, which will evaluate current drug use behaviors, medical history, and OUD treatment engagement status.
The 3 groups in the trial
- Arm 1: Peer navigator + mobile phone-assisted interventionTreatment being tested
Enrolled study participants randomized to this arm will proceed with the standard of care referral for MAT linkage at the study site and also be given a) access to the mobile App intervention for use in the three months period from randomization, as the participant transitions from the ED or hospital to outpatient MAT; b) a study-assigned Peer Navigator who will provide support for linkage and engagement in MAT care over the three months.
Treatment: Mobile phone-assisted intervention, Peer navigator, and Standard of care referral for out-patient MAT
- Arm 2: Peer navigator onlyExisting treatment, for comparison
Enrolled study participants in this arm will proceed with the standard of care referral for MAT linkage at the study site and also be given a study-assigned Peer Navigator who will provide support for linkage and engagement in the three months period from randomization, as the participant transitions from the ED or hospital to outpatient MAT.
Treatment: Peer navigator and Standard of care referral for out-patient MAT
- Arm 3: Standard of Care onlyOther group
Enrolled study participants in this arm will proceed with the standard of care referral for MAT linkage at the study site. The participants will not have access to the mobile Health App intervention and will not be assigned a study Peer Navigator.
Treatment: Standard of care referral for out-patient MAT
