Abstract Background Long-acting injectable antiretrovirals (LAI-ARVs) for HIV prevention and treatment have been demonstrated in clinical trials to be non-inferior to daily oral medications, providing an additional option to help users overcome the challenges of daily adherence. Approval and implementation of these regimens in low- and middle-income settings have been limited. Method This study describes the anticipated barriers and facilitators to implementing LAI-ARVs in Vietnam to inform future roll-out. From July to August 2022, we conducted 27 in-depth interviews with healthcare workers and public health stakeholders involved in HIV programs at national, provincial, and clinic levels across four provinces in Vietnam. The interviews followed a semi-structured questionnaire and were audio recorded. Data were analyzed using a rapid thematic analysis approach to identify facilitators and barriers to the adoption of LAI-ARVs. Results In total, 27 participants from 4 provinces were interviewed including 14 (52%) men and 13 (48%) women. Participants median age was 48 years and they had 11.5 years of experience with HIV services and programs. Perceived user-level facilitators included the greater convenience of injectables in comparison to oral regimens, while barriers included the increased frequency of visits, fear of pain and side effects, and cost. Clinic-level facilitators included existing technical capacity to administer injections and physical storage availability in district health centers, while barriers included lack of space and equipment for administering injections for HIV-related services, concerns about cold chain maintenance for LAI-ART, and workload for healthcare workers. Health system-level facilitators included existing mechanisms for medication distribution, while barriers included regulatory approval processes and concerns about supply chain continuity. Conclusion Overall, participants were optimistic about the potential impact of LAI-ARVs but highlighted important considerations at multiple levels needed to ensure successful implementation in Vietnam. Clinical trial number Not applicable.

Development of a robust technical assistance system is an essential component of a sustainable HIV response. Vietnam’s National HIV Program is transitioning from a largely donor-funded programme to one primarily supported by domestic resources. Telehealth interventions are increasingly being used for training, mentoring and expert consultation in high-resource settings and hold significant potential for use as a tool to build HIV health worker capacity in low and middle-income countries. We designed, implemented and scaled up a novel HIV telehealth programme for Vietnam, with the goal of building a sustainable training model to support the country’s HIV workforce needs. Over a 4-year period, HIV telehealth programmes were initiated in 17 public institutions with participation of nearly 700 clinical sites across 62 of the 63 provinces in the country. The telehealth programme was used to deliver certificate training courses, provide clinical mentoring and case-based learning, support programme implementation, provide coaching in quality improvement and disseminate new guidelines and policies. Programme evaluation demonstrated improved health worker self-reported competence in HIV care and treatment and high satisfaction among the programme participants. Lessons learnt from Vietnam’s experience with telehealth can inform country programmes looking to develop a sustainable approach to HIV technical assistance and health worker capacity building.
