Improved postoperative outcomes in pediatric major surgery: evidence from hospital volume analysis.

Abstract

This study aimed to examine the association between hospital volume and postoperative outcomes in pediatric major surgery using a nationwide database. The study included pediatric patients who underwent first major elective inpatient surgery and hospitalization for more than 1day. The results showed no significant difference in the risk of 30-day postoperative mortality based on hospital volume. However, patients in the middle- and high-volume groups had significantly lower rates of 30-day major complications, particularly deep wound infection. In terms of 90-day postoperative outcomes, patients in the high-volume group had a significantly lower risk of mortality and lower rates of major complications, particularly deep wound infection, pneumonia, and septicemia. Conclusions: The study suggests that pediatric patients undergoing major surgery in high and middle-volume groups have better outcomes in terms of major complications compared to the low-volume group. What is Known: • Limited evidence exists on the connection between hospital volume and pediatric surgery outcomes. What is New: • A Taiwan-based study, using national data, found that high and middle hospital-volume groups experienced significantly lower rates of major complications within 30 and 90 days after surgery. • High-volume hospitals demonstrated a substantial decrease in the risk of 90-day postoperative mortality. • The study underscores the importance of specialized pediatric surgical centers and advocates for clear guidelines for hospital selection, potentially improving outcomes and informing future health policies.
