Patient and clinic staff perspectives on the implementation of a long-acting injectable antiretroviral therapy program in an urban safety-net health system.

Background: Long-acting injectable cabotegravir plus rilpivirine (LAI CAB/RPV) has several potential benefits over daily oral formulations for HIV treatment, including the potential to facilitate long-term adherence and reduce pill fatigue. We aimed to assess facilitators of and barriers to LAI CAB/RPV implementation and delivery through the perspectives of physicians and clinical staff, and the experiences of LAI CAB/RPV use among people living with HIV (PLWH) at a Ryan-White supported safety-net clinic in North Texas.

Methods: We conducted semi-structured interviews with recruited clinic staff (physicians, nurses, and support staff) involved with LAI CAB/RPV implementation and PLWH who switched to LAI CAB/RPV and consented to participate in individual interviews. Data were collected from July to October 2023. Our interview guide was informed by the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM), and Proctor Implementation Outcomes frameworks. Qualitative data were analyzed using a rapid qualitative analysis approach to summarize key themes.

Results: We recruited and interviewed 15 PLWH who transitioned to LAI CAB/RPV and 11 clinic staff serving these patients. PLWH conveyed that emotional and informational support from family or a trusted clinician influenced their decision to switch to LAI CAB/RPV. PLWH also reported that injectable treatment was more effective, convenient, and acceptable than oral antiretroviral therapy. Clinic staff and physicians reported that staff training, pharmacist-led medication switches, flexible appointments, refrigeration space and designated room for injection delivery facilitated implementation. Clinic staff cited medication costs, understaffing, insurance prior authorization requirements, and lack of medication access through state drug assistance programs as critical barriers.

Conclusions: Our study offers insights into real-world experiences with LAI usage from the patient perspective and identifies potential strategies to promote LAI CAB/RPV uptake. The barriers to and facilitators of LAI CAB/RPV program implementation reported by clinic staff in our study may be useful for informing strategies to optimize LAI CAB/RPV programs.
