Abstract

Background: Congenital heart disease consumes significant health care resources; however, there are limited data regarding factors affecting resource utilizationThe purpose of this study was to evaluate variation between centers in total hospital costs for 4 congenital heart operations of varying complexity and associated factorsMethods and Results: The Premier Database was used to evaluate total cost in children undergoing isolated atrial septal defect (ASD) repair, ventricular septal defect (VSD) repair, tetralogy of Fallot (TOF) repair, or arterial switch operation (ASO) from 2001 to 2007Mixed models were used to evaluate the impact of center on total hospital costs adjusting for patient and center characteristics and length of stayA total of 2124 patients were included: 719 ASD (19 centers), 792 VSD (20 centers), 420 TOF (17 centers), and 193 ASO (13 centers)Total cost increased with complexity of operation from median $12 761 (ASD repair) to $55 430 (ASO)In multivariable analysis, models that accounted for center effects versus those that did not performed significantly better for all 4 surgeries (all P≤0.01)The proportion of total cost variation explained by center was 19% (ASD repair), 11% (VSD repair), 6% (TOF repair), and 3% (ASO)Higher-volume centers had significantly lower hospital costs for ASD and VSD repair but not for TOF repair and ASOConclusions: Total hospital costs varied significantly by center for all congenital heart surgeries evaluated, even after adjustment for patient and center characteristics and length of stayDifferences among centers were most prominent for lower complexity procedures.
