• “Those People Motivate and Inspire Me to Take My Treatment.” Peer Support for Adolescents Living With HIV in Cape Town, South Africa

  Journal of the International Association of Providers of AIDS Care (JIAPAC) · 2021 · 40 citations

  Adherence to antiretroviral therapy (ART) and psychosocial support to manage stigma and disclosure is essential for adolescents living with HIV (ALHIV). Peer support groups can help ALHIV and their families live successfully with HIV. This qualitative study aimed to examine adolescent and caregiver perspectives on peer support groups. Three themes emerged: (1) peer support encouraged adherence to ART, (2) serostatus disclosure outside the family was perceived as difficult, and (3) the peer suppo…

• Cost-effectiveness of differentiated care models that incorporate economic strengthening for HIV antiretroviral therapy adherence: a systematic review

  Cost Effectiveness and Resource Allocation · 2024-05-24 · 4 citations

  reviewOpen accessSenior authorCorresponding

  BACKGROUND: There is some evidence that differentiated service delivery (DSD) models, which use a client-centered approach to simplify and increase access to care, improve clinical outcomes among people living with HIV (PLHIV) in high HIV prevalence countries. Integrating economic strengthening tools (e.g., microcredit, cash transfers, food assistance) within DSD models can help address the poverty-related barriers to HIV antiretroviral therapy (ART). Yet there is minimal evidence of the cost-ef…
