Improving Retention and HIV Viral Load Suppression among the Adolescents Living with HIV in TASO Soroti and TASO Mbale Centers of Excellence using Operation Triple Zero Model: A before and after study protocol

Abstract Background Retention and HIV viral load suppression remains suboptimal among the adolescents living with HIV in many settings including TASO Uganda, despite the implementation of interventions such as regimen optimization and community-based approaches such as multi-drug dispensing. To this end, the implementation of additional intervention is proposed to address gaps in current programming which include inadequate centralization of the HIV positive adolescents in the designs. This study, thus proposes to adapt and implement the operation triple zero (OTZ) model in TASO Soroti and Mbale centers to improve both retention and viral load suppression among the adolescents. Methodology A before and study design is preferred, employing both qualitative and quantitative approaches. To identify barriers and facilitators to retention and Viral load suppression among the ALHIV, secondary data, focused group discussions and key informant interviews will be used to understand perspectives of the adolescents, their caregivers and the health-workers. The consolidated framework for implementation research (CFIR) will help in designing the intervention while knowledge to action (K2A) will support the adaptation process. To test the intervention, Reach, Effectiveness, Adaption, Implementation and Maintenance (RE-AIM) framework will be used. A paired t-test will be used to compare means of retention and viral load suppression in the before and after study periods. Discussion This study aims at adapting and implementing the OTZ model in TASO Soroti and Mbale Centers of Excellence (COEs) to attain optimal retention and viral load suppression among the HIV positive adolescents in care. Uganda is yet to adapt the touted OTZ model and findings from this study will be important in providing the necessary lessons for potential scale up of the model. Furthermore, results of this study could potentially provide more additional evidence for the effectiveness of OTZ in attaining optimal HIV treatment outcomes among the adolescents living with HIV.
