INTRODUCTION: Acute childhood illnesses, such as malaria, pneumonia, and diarrhoea, represent the leading causes of under-five mortality in Uganda. Given that most early child deaths are treatable with timely interventions, emergency units dedicated to paediatric populations have been established in the country. In light of recent developments, the department of paediatrics at Makerere University requested a needs assessment in the paediatric acute care unit (PACU) at Mulago National Referral Hospital, which could guide the development of a new training curriculum for medical providers. METHODS: We administered a survey for medical providers working in the PACU at Mulago Hospital, which assessed their self-rated comfort levels with paediatric assessment, treatment, and teamwork skills. We also conducted focus groups with a smaller subset of medical providers to understand barriers and facilitators to paediatric emergency and critical care. RESULTS: Of 35 paediatric assessment, treatment, and teamwork skills, 29 (83%) questions had the median comfort rating of 6 or 7 on a 7-point Likert scale. The remaining 6 (17%) skills had a median comfort rating of 5 or lower. Focus groups identified a number of major barriers to caring for critically ill children, including limited resources and staffing, training gaps, and challenges with interprofessional teamwork. In terms of training development, focus group participants suggested continuous training for all medical providers working in the PACU led by local leaders. DISCUSSION: This study identified the need and desirability of continuous trainings in the PACU. Key components include objective skills assessment, simulation-based scenarios, and interprofessional teamwork. Training development should be augmented by increases in resources, staffing, and training opportunities in collaboration with the Uganda Ministry of Health.
