BackgroundThere is a growing number of adolescents and young adults with HIV who require transfer of care from pediatric/ adolescent clinics to adult ART clinic. Currently, adolescents are largely in the care of pediatricians; but as they grow, they transition to adult HIV clinics. The purpose of this study was to explore the facilitators and barriers of transitioning among adolescents from adolescent clinics to adult ART clinics.MethodAn explorative qualitative approach was utilised for this study. Eighteen focus group discussions were held in nine health facility with (191) adolescents and young people in order to capture their experiences, barriers and facilitators regarding transitioning to adult clinics. The focus group discussions were audio recorded and transcribed. The Silences Framework using thematic approach guided the analysis.Results The key emerging issues were: Care provided in the adolescent clinics, Unfriendly adults, stigma and discrimination, Congestion and long waiting time, health providers in adult clinics were barriers to transitioning. Moving as a cohort, Transition preparation, care in clinics, positive living, support from the guardian and Young adolescent program Support (YAPS) could facilitate readiness and transitioning.ConclusionAdolescents and young people expressed fear to transition to adult clinics mainly because of the perceived better care provided in adolescent clinic, thus constituting a barrier to smooth transition A range of individual, social and health system and services-related factors hindered transitioning. Expectation of transitioning as a group, assurance of similar care as in the adolescent clinic, and guarantees of confidentiality, privacy and autonomy in decision-making for care were perceived as facilitators. There is need to strengthen implementation of age-appropriate care and individualized case management during care transition at all health facilities. Furthermore, the findings suggest the need to create supportive family, peer, and healthcare environments for adolescent transition.
