Health services and programmatic responses to improving adolescent HIV care in Lusaka, Zambia: A descriptive qualitative study

BACKGROUND: Adolescents living with human immunodeficiency virus (HIV) face disproportionately poor treatment outcomes because of a combination of psychosocial, structural and health systems challenges. Despite efforts to implement adolescent-friendly and differentiated service delivery models in Zambia, gaps remain in the organisation and delivery of care. AIM: This study aimed to explore how HIV services for adolescents are delivered and experienced by healthcare workers and programme managers in Lusaka District. SETTING: The study was conducted across six health facilities in Lusaka District, Zambia, representing different levels of the health system and providing HIV care to adolescents. METHODS: A descriptive qualitative design was employed. Thirty purposively selected participants (24 healthcare workers and six HIV programme managers) participated in individual in-depth interviews (IDIs) conducted between 20 February 2025 and 30 April 2025 using a semi-structured interview guide. Data were audio-recorded, transcribed verbatim and analysed using inductive content analysis. RESULTS: Inductive content analysis identified three themes: programmatic responses, highlighting strategic leadership, policy direction, adolescent-focused service delivery and workforce capacity building; implementation challenges, including inadequate infrastructure, health system limitations and individual-level barriers; and opportunities for improved programmatic response and service delivery, emphasising improvements in policy, health systems, infrastructure and service delivery. CONCLUSION: Although notable progress has been made in expanding adolescent HIV services in Lusaka, gaps in infrastructure, workforce and social support continue to affect programme effectiveness. Strengthening adolescent-responsive and sustainable care is essential to improve retention, viral suppression and Zambia's progress towards the Joint United Nations Programme on HIV/AIDS (UNAIDS) 95-95-95 targets in the adolescent HIV cascade.Contribution: This study highlights barriers and opportunities in adolescent HIV programming in Lusaka, emphasising leadership, policy, service delivery and workforce capacity, while noting ongoing system and individual challenges. The findings can inform policy and practice to strengthen adolescent-responsive HIV care in Zambia and similar contexts.
