Qualitative data
Data were collected by trained study staff before and will be collected after the trial through in-depth interviews in English, Amharic, Afan Oromo, isiZulu, and Sepedi. Participants included and will include program managers, providers, community health team members, and child caregivers. Interviews will be transcribed, translated, and coded by experienced qualitative researchers. The baseline interview focused on perceptions of the planned intervention including barriers and facilitators to its implementation. Post-trial interviews will focus on the intervention arm and will assess each stakeholder groups’ perception of the intervention’s acceptability and feasibility along with lessons learned. All participants provided or will be asked to provide informed consent for participation in each interview. Confidentiality will be maintained by not using names of people, clinics, or locations within the interview and eliminating specified people or places during transcription. We plan to use thematic analysis guided by the Consolidated Framework for Implementation Research (CFIR) [
