Pilot Study of an Adapted Partner Navigation Intervention Booster Session for Sustained Healthcare Engagement Among People Who Inject Drugs

June 1, 2026 updated by: University of California, San Francisco

This study builds upon an ongoing NIH-funded randomized controlled trial (R01DA053325) evaluating a Partner Navigation Intervention to increase hepatitis C virus (HCV) treatment initiation among young adult people who inject drugs (PWID) and their injecting partners in San Francisco. The proposed research includes secondary analyses of existing trial data, additional survey measures, qualitative interviews, and a pilot intervention adaptation.

The study has two primary objectives. First, it examines how racialized discrimination (structural, interpersonal, and internalized) affects HCV treatment initiation and dyadic partner support processes within injecting partnerships. Second, it evaluates whether a brief, adapted "booster" partner navigation session delivered at HCV treatment completion can improve engagement in ongoing healthcare.

Participants include adults (≥18 years) who inject drugs and have been diagnosed with HCV, along with their primary injecting partners. Study activities include longitudinal surveys, qualitative interviews with a subset of participants, and a pilot intervention session with follow-up evaluation.

This research addresses critical gaps in understanding how social relationships and structural inequities influence healthcare engagement among PWID. Findings will inform culturally responsive adaptations to dyadic interventions and improve continuity of care in a population disproportionately affected by HCV and systemic barriers to healthcare.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Partner Navigation Booster Session
Injecting dyads (index participant and their primary injecting partner) receive one adapted Partner Navigation Intervention booster session at the point of HCV treatment completion, designed to strengthen partnership-based support for sustained healthcare engagement beyond HCV care.
Behavioral: Partner navigation intervention booster session
A single adapted dyadic session delivered to PWID and their primary injecting partner at the point of HCV treatment completion. The session builds on the original two-session Partner Navigation Intervention (PNI) developed in the YETI study (R01DA053325) and is adapted to target partnership-based support for broader post-treatment healthcare access, including primary care, mental health, and harm reduction services. Session content includes collaborative goal-setting, barrier identification, and partner communication skills.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Acceptability of the booster session
Time Frame: 1 week

Feasibility: recruitment rate
Time Frame: up to 25 weeks
Proportion of eligible dyads who consent and enroll, calculated as the number enrolled divided by the number approached and screened.
up to 25 weeks
Feasibility: retention rate
Time Frame: up to 25 weeks
Proportion of enrolled dyads who complete the booster session, calculated as session completion rate among enrolled participants.
up to 25 weeks
Fidelity to session protocol
Time Frame: 1 hour
Adherence to the adapted booster session protocol assessed by trained observer using a structured fidelity checklist; reported as proportion of session components delivered as intended.

IPD Plan Description

This is a pilot/feasibility study with a small target enrollment of 15-25 dyads (30-50 individuals). Given the small sample size and the sensitive nature of the study population (PWID, involving disclosure of illegal drug use behaviors and medical history), individual-level data sharing poses meaningful re-identification risk even after de-identification. Aggregate de-identified findings will be reported in peer-reviewed publication and on ClinicalTrials.gov per standard reporting requirements.
