HIV Exposure Prophylaxis Delivery in a Low-barrier Substance Use Disorder Bridge Clinic during a Local HIV Outbreak at the Onset of the COVID-19 Pandemic

PrEP facilitators and barriers in substance use bridge clinics for women who engage in sex work and who use drugs

BACKGROUND

Women who engage in sex work and use drugs (WSWUD) experience disproportionate HIV risks. Substance use treatment bridge clinics offer an opportunity to increase HIV pre-exposure prophylaxis (PrEP) delivery to WSWUD, but research on best practices is lacking. Therefore, we explored facilitators and barriers to PrEP across the PrEP care continuum in these settings.

METHODS

Bridge clinic and affiliated harm reduction health service providers and WSWUD from Boston were recruited using passive and active outreach between December 2021 and August 2022. Participants were invited to take part in semi-structured phone or in-person interviews to explore HIV prevention and PrEP care experiences overall and within bridge clinic settings. Deductive codes were developed based on HIV risk environment frameworks and the Information-Motivation-Behavioral Skills model and inductive codes were added based on transcript review. Grounded content analysis was used to generate themes organized around the PrEP care continuum.

RESULTS

The sample included 14 providers and 25 WSWUD. Most WSWUD were aware of PrEP and more than half had initiated PrEP at some point. However, most who initiated PrEP did not report success with daily oral adherence. Providers and WSWUD described facilitators and barriers to PrEP across the steps of the care continuum: Awareness, uptake, adherence, and retention. Facilitators for WSWUD included non-stigmatizing communication with providers, rapid wraparound substance use treatment and HIV services, having a PrEP routine, and service structures to support PrEP adherence. Barriers included low HIV risk perceptions and competing drug use and survival priorities. Provider facilitators included clinical note templates prompting HIV risk assessments and training. Barriers included discomfort discussing sex work risks, competing clinical priorities, and a lack of PrEP adherence infrastructure.

CONCLUSION

WSWUD and bridge clinic providers favored integrated HIV prevention and substance use services in harm reduction and bridge clinic settings. Harm reduction and bridge clinic programs played a key role in HIV prevention and PrEP education for WSWUD. Effective behavioral and structural interventions are still needed to improve PrEP adherence for WSWUD.

Peer recovery coaching for comprehensive HIV, hepatitis C, and opioid use disorder management: The CHORUS pilot study

Introduction

Amidst a surge in HIV and hepatitis C virus (HCV) infections in persons who use drugs, medications that effectively prevent HIV and treat opioid use disorder and HCV remain underutilized.

Methods

We developed a 6-month peer recovery coaching intervention (brief motivational interviewing followed by weekly virtual or in-person coaching) and collected data on uptake of medications for opioid use disorder (MOUD), HIV pre-exposure prophylaxis (PrEP), and HCV treatment. The primary outcomes were intervention acceptability and feasibility.

Results

At a Boston substance use disorder bridge clinic, we enrolled 31 HIV-negative patients who used opioids. Participants reported high intervention satisfaction at 6 months (95% "satisfied" or "very satisfied"). At study completion, 48% of the participants were on MOUD, 43% who met CDC guidelines were on PrEP, and 22% with HCV were engaged with treatment.

Conclusions

A peer recovery coaching intervention is feasible and acceptable, with positive preliminary findings regarding MOUD, PrEP and HCV treatment uptake.

Effect of police action on low-barrier substance use disorder service utilization

Background

Police action can increase risky substance use patterns by people who use drugs (PWUD), but it is not known how increased police presence affects utilization of low-barrier substance use disorder bridge clinics. Increased police presence may increase or decrease treatment-seeking behavior. We examined the association between Operation Clean Sweep (OCS), a 2-week police action in Boston, MA, and visit volume in BMC’s low-barrier buprenorphine bridge clinic.

Methods

In this retrospective cohort, we used segmented regression to investigate whether the increased police presence during OCS was associated with changes in bridge clinic visits. We used General Internal Medicine (GIM) clinic visit volume as a negative control. We examined visits during the 6 weeks prior, 2 weeks during, and 4 weeks after OCS (June 18–September 11, 2019).

Results

Bridge clinic visits were 2.8 per provider session before, 2.0 during, and 3.0 after OCS. The mean number of GIM clinic visits per provider session before OCS was 7.0, 6.8 during, and 7.0 after OCS. In adjusted segmented regression models for bridge clinic visits per provider session, there was a nonsignificant level increase (0.643 P = 0.171) and significant decrease in slope (0.100, P = 0.045) during OCS. After OCS completed, there was a significant level increase (1.442, P = 0.003) and slope increase in visits per provider session (0.141, P = 0.007). There was no significant change in GIM clinic volume during the study period.

Conclusions

The increased policing during OCS was associated with a significant decrease in bridge clinic visits. Following the completion of OCS, there was a significant increase in clinic visits, suggesting pent-up demand for medications for opioid use disorder, a life-saving treatment.
