Factors Associated with Retention in HIV Care Among HIV-Positive Adolescents in Public Antiretroviral Therapy Clinics in Ibanda District, Rural South Western Uganda.

Background: Retention in antiretroviral therapy (ART) care is a key indicator of Human Immunodeficiency Virus (HIV) treatment success as it improves adherence, critical for better treatment outcomes and prevention of drug resistance. HIV treatment among adolescents living with HIV (ALHIV) is characterized by loss to follow-up, poor ART adherence, and eventual death. This study assessed retention in ART care and the associated factors among ALHIV in Ibanda district, rural South Western Uganda.

Methods: This was a retrospective cohort study using clinical data from ALHIV enrolled from 2019 to 2020 in eight health facilities in Ibanda district. Data from the Electronic Medical Record (EMR) system was extracted to assess the associated factors and participants' status two years after enrollment. Data were analyzed using EPIdata version 3.1 in which Univariate and multivariate cox proportional hazard regression analyses were determined. A hazard ratio (HR) at a 95% confidence interval was obtained, and a P-value <0.05 was considered statistically significant.

Results: Eighty-four ALHIV comprising 86.9% (N = 73) females were enrolled. The majority 63.1% (N = 53) resided in semi/peri-urban, and 44.0% (N = 37) stayed less than 5 km from the facility. Only 35.7% (N = 30) were active on ART, while 17 (20.2%) and 36 (42.9%) were lost to follow-up and transfer-outs, respectively. Factors associated with low retention were: ALHIV that moved 5-10Km (HR = 5.371; 95% CI: 1.227-23.5050, p = 0.026), used differential service delivery model was Facility-Based Group (FBG) (HR = 12.419; 95% CI: 4.034-38.236, p < 0.001) and those enrolled on the Young Adolescent Program Support (YAPs) (HR = 4.868; 95CI:1.851-12.803; p = 0.001). Retention reduced with increasing ART duration, ALHIV on (TDF/3TC/EFV) (p < 0.001), lived more than 10Km (p = 0.043) and did not benefit from any intervention (p < 0.001).

Conclusion: Results showed low retention in care and the urgent need to strengthen individual case management strategies for ALHIV, thus interventions focusing on peer support are desired.
