Brief summary

PrEPare for Work is a randomized controlled trial (RCT) whose goal is to test the efficacy of a behavioral intervention (Short Title: PrEPare for Work) in improving PrEP uptake, adherence, and persistence among male sex workers (MSW)

Detailed description

A theory-based, manualized intervention -called PrEPare for Work-includes two separate but complementary interventions that address MSW-specific behavioral, economic, interpersonal & structural-level barriers to accessing and adhering to PrEP: 1) peer-led, strengths-based case management (SBCM) for PrEP linkage and uptake; and 2) a technology and counseling intervention to optimize PrEP adherence (once they have access to PrEP). This research will test the PrEPare for Work intervention in a fully-powered RCT to assess efficacy and cost-effectiveness.

Interventions

BEHAVIORALStage 1 Strength Based Case Management (SBCM) Condition

Intervention participants will receive a trained SBCM to motivate, support, and assist in linkage to PrEP prescribers to help facilitate obtaining PrEP medication to initiate treatment.

BEHAVIORALStage 2 PrEPare for Work Intervention Condition

Intervention participants will receive 1-on-1 adherence counseling and personalized daily text messaging reminders to increase PrEP adherence. Intervention participants will undergo three adherence intervention sessions (once per week for 3 weeks) with interventionist.

Inclusion criteria

Inclusion * Age: 18 years or older * Assigned male sex at birth * Identifies as male at enrollment * Report having engaged in condomless anal sex with another man in the past 3 months * Report having exchanged sex for money, drugs, items of value, or a place to stay with another man in the past 3 months * Report HIV status as negative or unsure * Not currently on PrEP * Able to understand and speak English or Spanish Exclusion * Unable to provide informed consent due to severe mental or physical illness, cognitive impairment, or substance intoxication at the time of interview (will use an adapted version of the Evaluation to Sign Consent Form65 to assess capacity) * Discovery of active suicidal ideation or major mental illness (e.g. untreated psychosis or mania) at the time of interview (these patients will be referred immediately for treatment) * Laboratory or clinical findings that would preclude PrEP initiation (e.g. Chronic Hepatitis B Virus infection, decreased creatinine clearance) * Participated in the pilot RCT and initiated PrEP during study participation

Design outcomes

Primary

MeasureTime frameDescription
Stage one: PrEP initiation2-month post Stage 1 randomizationStage one: PrEP initiation will be measured via verification of prescription filled within two months post-randomization, associated medical records from a PrEP prescriber, and self-report.
Stage two: PrEP adherence12-month post Stage 2 randomizationStage two: PrEP adherence will be measured via tenofovir concentration in hair. Self-reported adherence will supplement biological monitoring data at 4-month intervals.

Secondary

MeasureTime frameDescription
PrEP persistence12-month post Stage 2 randomizationPrEP persistence will be measured via medical records and self-report. We will assess PrEP persistence using medical and pharmacy records to confirm provider follow-up visits and prescription refill maintenance. As per Coy et al., PrEP persistence will be defined as having ≥16 days of PrEP medication filled per 30-day period, for at least three-quarters of the months since initiation to study completion (\ 9 months).
