Purpose: Most pediatric surgeons perform <2 esophageal atresia and tracheoesophageal fistula (EA/TEF) repairs annually. We aimed to determine whether higher surgeon and hospital volumes are associated with better outcomes after EA/TEF repair.
Methods: Neonates with a diagnosis and repair of EA/TEF at their index hospital admission in the Pediatric Health Information System from 1/2000 to 9/2015 were included. For each patient, hospital and surgeon operative volumes were defined as the number of EA/TEF cases treated in the previous 365 days. Propensity score weighting was used to estimate relationships between operative volumes and rates of in-hospital mortality, readmission within 30 days, and readmission, reoperation, and dilation within one year.
Results: Among 3085 patients, lower birth weight, earlier gestational age, the presence of congenital heart disease, and certain other anomalies were associated with higher mortality. In risk-adjusted analyses, there were no significant differences in mortality or any other outcome based on hospital or surgeon volume alone or when comparing low- or high-volume surgeons practicing at low- or high-volume hospitals.
Conclusions: Neither surgeon nor hospital volume significantly impacted outcomes after EA/TEF repair. Our findings imply that selective referral and pediatric surgeon subspecialization in EA/TEF may not translate to improved outcomes.
Type of study: Retrospective comparative study LEVEL OF EVIDENCE: Level III.
