Preventing avoidable hospital admissions after emergency care in humanitarian settings: a cross-sectional review of Médecins Sans Frontières emergency departments.

EDs are critical in improving the agility and access to emergency care (EC) in humanitarian settings. This study demonstrated that EC provision resulted in the majority of patients being discharged from EDs, helping prevent avoidable hospital admissions. These results could help better understand the healthcare needs of vulnerable populations, improve responsiveness to emergency conditions and support programmatic planning in humanitarian settings.
