We read with interest the article by Mehl et al. reporting hospital-level variation in postoperative mortality among preterm infants treated at U.S. pediatric centers. In a large national cohort with risk- and reliability-adjusted analyses, the authors show substantial variation in mortality, most pronounced at lower gestational ages.1

In brief

This letter discusses hospital-level variation in postoperative mortality among preterm infants at U.S. pediatric centers. The commentary addresses risk-adjusted analyses showing substantial mortality differences, particularly in extremely preterm neonates undergoing surgical procedures.

- Significant hospital-level variation exists in postoperative mortality for preterm infants across U.S. pediatric centers. - Mortality variation is most pronounced in infants at lower gestational ages, indicating higher-risk populations. - Risk- and reliability-adjusted analyses confirm these differences persist even after accounting for patient complexity.
