OBJECT Recently published data have suggested an increase in adverse outcomes in pediatric patients after insertion or revision of a ventricular CSF diversion shunt after a same-day weekend procedure. The authors undertook an evaluation of the impact of weekend admission and time to shunting on surgery-related quality outcomes in pediatric patients who underwent ventricular shunt insertion or revision. METHODS Pediatric patients with hydrocephalus who underwent ventriculoperitoneal, ventriculoatrial, or ventriculopleural shunt placement were selected from the 2000-2010 Nationwide Inpatient Sample and Kids' Inpatient Database. Multivariate regression analyses (adjusted for patient, hospital, case severity, and time to shunting) were used to determine the differences in inpatient mortality and routine discharge rates among patients admitted on a weekday versus those among patients admitted on a weekend. RESULTS There were 99,472 pediatric patients with shunted hydrocephalus, 16% of whom were admitted on a weekend. After adjustment for disease severity, time to procedure, and admission acuity, weekend admission was not associated with an increase in the inpatient mortality rate (p = 0.46) or a change in the percentage of routine discharges (p = 0.98) after ventricular shunt procedures. In addition, associations were unchanged after an evaluation of patients who underwent shunt revision surgery. High-volume centers were incidentally noted in multivariate analysis to have increased rates of routine discharge (OR 1.04 [95% CI 1.01-1.07]; p = 0.02). CONCLUSIONS Contrary to those of previous studies, the authors' data suggest that weekend admission is not associated with poorer outcomes for ventricular shunt insertion or revision. Increased rates of routine discharge were noted at high-volume centers.
