Human-Centered Design for Public Health Innovation: Codesigning a Multicomponent Intervention to Support Youth Across the HIV Care Continuum in Mozambique.

Adolescents and young people represent a growing proportion of people living with HIV (AYAHIV), and there is an urgent need to design, implement, and test interventions that retain AYAHIV in care. Using a human-centered design (HCD) approach, we codesigned CombinADO, an intervention to promote HIV viral suppression and improve antiretroviral therapy (ART) adherence and retention in care among AYAHIV in Nampula, Mozambique. The HCD process involves formative design research with AYAHIV, health care providers, parents/caretakers, and experts in adolescent HIV; synthesis of findings to generate action-oriented insights; ideation and prototyping of intervention components; and a pilot study to assess feasibility, acceptability, and uptake of intervention components.
