Abstract
ObjectiveTo determine retention in care and virologic suppression among HIV-infected adolescents and young adults attending an adolescent-friendly clinic compared to those attending the standard pediatric clinic at the same site.DesignRetrospective cohort analysis.SettingGovernment supported, hospital-based antiretroviral clinic in KwaZulu-Natal, South Africa.ParticipantsTwo hundred forty-one perinatally HIV-infected adolescents and young adults aged 13 to 24 years attending an adolescent-friendly clinic or the standard pediatric clinic from April 2007 to November 2015.InterventionAttendance in an adolescent-friendly clinic compared to a standard pediatric clinic.Outcomes measuresRetention in care defined as one clinic visit or pharmacy refill in the prior 6 months; HIV-1 viral suppression defined as < 400 copies/ml.ResultsOverall, among 241 adolescents and young adults, retention was 89% (214/241) and viral suppression was 81% (196/241). Retention was higher among those attending adolescent clinic (95%) versus standard pediatric clinic (85%; OR 3.7; 95% confidence interval (CI) 1.2–11.1; p = 0.018). Multivariable logistic regression adjusted for age at ART initiation, gender, pre-ART CD4 count, months on ART, and tuberculosis history indicated higher odds of retention in adolescents and young adults attending adolescent compared to standard clinic (AOR = 8.5; 95% CI 2.3–32.4; p = 0.002). Viral suppression was higher among adolescents and young adults attending adolescent (91%) versus standard pediatric clinic (80%; OR 2.5; 95% CI 1.1–5.8; p = 0.028). A similar multivariable logistic regression model indicated higher odds of viral suppression in adolescents and young adults attending adolescent versus standard pediatric clinic (AOR = 3.8; 95% CI 1.5–9.7; p = 0.005).ConclusionAdolescents and young adults attending an adolescent-friendly clinic had higher retention in care and viral suppression compared to adolescents attending the standard pediatric clinic. Further studies are needed to prospectively assess the impact of adolescent-friendly services on these outcomes.
Highlights
In 2013, an estimated 870,000 adolescents and young adults aged 15–24 years were living with HIV in South Africa.[1]

Summary
In 2013, an estimated 870,000 adolescents and young adults aged 15–24 years were living with HIV in South Africa.[1]. Numerous observational cohort studies in South Africa report significantly poorer retention in care and viral suppression rates for adolescents compared to older adults.[11,12,13,14,15,16,17,18,19,20] The World Health Organization (WHO) recently issued guidelines on provision of adolescent-friendly services to help overcome many of the barriers noted above to improve these outcomes;[21] there is little evidence of documented benefit from these services.[22, 23] A qualitative study with healthcare providers suggested that peer support and collaboration with healthcare providers may improve care for older HIV-infected adolescents and young adults in sub-Saharan Africa;[24] studies with objective outcomes are needed
