Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will provide HIV prevention and related support services to men who have sex with men and transgender women who have substance use disorders and are either leaving jail or recently released from jail. The researchers will compare the utilization of HIV prevention and other support services between individuals who receive routine case management provided following enrollment to those who have access to GeoPassport, a global position service (GPS)-based mobile app, incentives, and peer mentor support.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators will enroll 200 people in jail or within 12 months post-release from incarceration. During the trial, half of participants will be randomized into a control group that will receive usual care consistent with the setting in which they live, along with referrals customized to their needs and preferences to share with a case manager. They will be compared to the other half of participants randomized to the intervention group that, in addition to receiving customized referral sources, will also receive the GeoPassport App, incentives, and the support of a trained Peer Mentor for six months. The GeoPassport App will provide participants with tools for tracking goals and progress toward meeting them, assistance in locating services, appointment and medication reminders, opportunities to provide feedback on service providers, and built-in tracking and distribution of rewards (incentives) for service utilization. GeoPassport will assist Peer Mentors in monitoring participants' service utilization. The Peer Mentors will provide encouragement, role modeling, accompaniment to appointments, and assistance with goal setting, problem-solving, and reducing logistical and psychosocial barriers to service engagement. The intervention can be delivered in person or remotely in order to comply with necessary social distancing during the COVID-19 pandemic. Participants in both groups will be followed to assess whether those offered the intervention are more likely to meet the specific prevention targets described in the Specific Aims. The intervention lasts 6 months from the start of participation. Participants are interviewed at 3, 6, and 9 months from the same point as the intervention.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The Mobile Enhanced Prevention Support (MEPS) intervention is designed to support, motivate, and facilitate engagement in preventive health care activities in the period of community reentry following jail. Three components: support from a selected Peer Mentor (PM), incentives, and a developed mobile application. Client-driven approach, in which participants are encouraged to address priorities and immediate needs for that they identify a client-centered needs assessment, prioritization, and wellness planning process, especially social determinants of health that may discourage or undermine preventive health measures.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standard of Care

A client-centered assessment of priorities and needs and customized prevention and testing referrals.

Group Type ACTIVE_COMPARATOR

Usual Care plus Customized Referrals

Intervention Type BEHAVIORAL

Participants in the control arm will continue to receive services they would normally receive consistent with the setting in which they were recruited. This includes substance use treatment in jail, substance use treatment at a residential recovery facility, and/or supportive housing services. The study will provide referrals customized to their needs and preferences.
