Key Points Question Is high emergency department (ED) pediatric readiness (6 domains of preparedness) associated with lower short-term and long-term mortality among children? Findings In this cohort study of 796 937 children cared for in 983 EDs, there was 60% to 76% lower odds of in-hospital death associated with care in high-readiness EDs; among a subset of 545 921 children followed up beyond hospitalization, the benefit of high-readiness EDs persisted to 1 year. If all these EDs had high pediatric readiness, an estimated 1442 pediatric deaths may have been prevented. Meaning These findings suggest that care in EDs with high pediatric readiness is associated with lower short-term and long-term mortality among children.
