Harm Reduction in HIV Primary Care for PLWH Who Use Drugs

April 21, 2026 updated by: Mary Hawk, University of Pittsburgh

Impact of Harm Reduction Care in HIV Clinical Settings on Stigma and Health Outcomes

People living with HIV (PLWH) who use drugs experience significant health disparities including lower rates of retention in HIV care and higher rates of unsuppressed viral load, resulting in secondary infections and increased mortality. The proposed study will used mixed methods to explore (a) the relationship between healthcare providers' attitudes towards working with PLWH who use drugs and providers' acceptance and practice of structural and relational harm reduction; (b) the degree to which relational harm reduction moderates the effect of intersectional stigma experienced in healthcare settings on patients' perceptions of their relationship with providers; (c) the degree to which structural HR moderates the relationship between the patient-provider relationship and clinical outcomes, and (d) whether patient-perceived HR approaches to care are directly associated with HIV clinical outcomes. The study will also use these findings to inform the development and pre-testing of an intervention to operationalize harm reduction in HIV clinical settings, using stakeholder-engaged and human-centered design approaches, presenting a novel path to reducing HIV health inequities for PLWH who use drugs.

Detailed Description

This observational study takes place across three study sites and will explore the extent to which harm reduction care mitigates stigma experienced in healthcare settings and contributes to improved clinical outcomes. This will be explored via the following aims.

Aim 1. Explore the relationship between healthcare providers' stigmatizing attitudes towards working with PLWH who use drugs and providers' acceptance and practice of structural and relational HR to elucidate the context for intervention development. Providers (n=125) working HIV clinics in Birmingham, AL and Pittsburgh, PA will be surveyed to understand subjective responses around preparedness for and delivery of HR care to PLWH who use drugs. A sequential explanatory mixed-methods approach will be utilized; surveys will be followed by semi-structured interviews (n=40) with multiple provider types in both regions to further explore HR perspectives and inform intervention development. It is hypothesized that providers with less stigmatizing attitudes toward serving people who use drugs are more likely to be accepting of relational and structural HR practices.

Aim 2. Explore the interplay between patient-perceived HR and stigma and clinical outcomes; specifically, the degree to which (a) relational HR moderates the effect of intersectional stigma experienced in healthcare settings (HIV- and substance use-related stigma and racial discrimination) on patients' perceptions of their relationship with providers, (b) structural HR moderates the relationship between the patient-provider relationship and clinical outcomes (ART adherence, retention in care, HIV and HCV viral suppression), and (c) patient-perceived HR care is directly associated with HIV clinical outcomes (see Figure 1). After qualitatively evaluating PAPHRS with HIV clinical and HR providers (n=20) and PLWH who use drugs (n=36), PLWH who use drugs (n=500) who receive care in the study sites will be surveyed to assess their perceptions of providers' relational HR care; experiences of intersectional stigma; and perceived quality of relationships with their providers. Other potential stigmatized identities (e.g., HCV) will be explored via patient focus groups (n=36). It is hypothesized that the effect of intersectional stigma on the patient-provider relationship is attenuated in higher degrees of relational HR care; structural HR attenuates the effect of poor patient-provider relationships on clinical outcomes; and higher degrees of HR care are associated with better clinical outcomes.

Aim 3. Using human-centered design approaches, develop and pre-test an intervention to operationalize HR care for PLWH who use drugs in HIV clinical settings. Results from Aims 1 and 2 will be shared with with stakeholders (n=20, PLWH who use drugs, clinical and HR providers) to develop an intervention. Acceptability and feasibility of the intervention design will be assessed with providers (n=12) in both regions.

Harm reduction aims to reduce negative effects of risky health behaviors without necessarily terminating the behaviors completely.Though often thought of as structural approaches (e.g., policy or syringe services), Harm reduction is also a relational approach to care focusing on non-punitive patient-provider interactions to promote autonomy. The degree to which harm reduction care is offered in study settings and is associated with clinical outcomes is the focus of this study.
