Abbreviations: CI, confidence interval; IQR, interquartile range; RSRR, risk‐standardized readmission rate.
Pediatric vs elderly adult RSRR comparisons performed in subset of 235 nonspecialty hospitals treating both pediatric and adult patients.
Median RSRR (IQR) for pediatric, young adult, middle‐aged adult, and elderly adult cohorts overall was 6.2% (5.4%, 7.6%), 9.5% (9.0%, 10.1%), 11.0% (10.2%, 11.9%), and 13.0% (11.9%, 14.1%), respectively.
