2.10. Ethics
This study was approved by the University of Witwatersrand (Johannesburg, South Africa) human research institutional review board (IRB) and the provincial ethics committee and registered with the ISRCTN (ISRCTN67031403). The IRB determined no written consent was necessary as health facilities (not individuals) were the subject and unit of analysis and the study required no study-specific data collection. Eligible facilities were invited to participate in the intervention and could decline without consequence. Interns participated in their work, under normal program circumstances; no study-specific data were collected on interns, negating their need for consent. This pragmatic trial was registered retrospectively, as it was instituted using an ongoing program and required no grant funding or prerequisites for registration. To the best of our knowledge, no additional trials are being conducted on the YHA program. Facilities in the control group were eligible to receive programmatic interns after completion of this study.
