Abstract summary 

Research on adolescent transitions out of pediatric HIV care has focused on high-income countries, with limited understanding of transitions in sub-Saharan Africa's public health sector.Patient file data were extracted through December 2017 for all 10- to 19-year olds ever initiated on antiretroviral therapy in a health district of the Eastern Cape, South Africa (n = 951). Pathways in HIV care were identified by tracing movements across facility care types and levels. Associations between pathways and viral failure, mortality, loss to follow-up, and viral load change were tested in sequential multivariable regressions. Analyses controlled for sociodemographic and treatment-related variables. Thematic analyses of semistructured health care provider interviews identified transition support at included facilities.Only 57.8% of adolescents had initiated antiretroviral therapy in pediatric care, and 20.4% of the total cohort had transitioned out of pediatric HIV care. Among the 42.2% who had initiated in nonpediatric care, 93.8% remained exclusively in nonpediatric care. Median age at first transition was 14 years. Two main pathways were identified: classical transition to adult HIV care (43.3%) and down referral transition to primary health care clinics (56.7%). Across pathways, 27.3% experienced cyclical transition or repeated movement between pediatric and nonpediatric care. Independent of covariates, adolescents with down referral transition were less likely to demonstrate viral failure (adjusted odds ratio, 0.21; 95% confidence interval: 0.10 to 0.42; P < 0.001). Mortality and loss to follow-up were not associated with either pathway. Median posttransition viral load change was not clinically significant (median, 0.00; interquartile range: 0.00-0.35) or associated with transition pathways. Health care providers described informal "protocols" for mitigating risk of negative posttransition HIV outcomes.This study proposes a contextually relevant model for transitions out of pediatric HIV care in South Africa. Feasible, scalable "protocols" may mitigate risk of worsening posttransition HIV outcomes.
