Variation in resource utilization in liver transplantation at freestanding children's hospitals.

ABSTRACT

We sought to examine the relationship between liver transplant-related total cost, patient outcome, and hospital resource utilization at freestanding children's hospitals. Using the PHIS database, a retrospective study of 374 patients that underwent liver transplantation at 15 freestanding children's hospitals from July 2010 to December 2012 was performed. One-year graft failure and patient mortality rates from July 2010 to December 2012 for each center were also obtained from the SRTR. There was a 5.1-fold difference in median cost (median $146 444, range $59 487-302 058, P<.001) between all centers. A 2.4-fold difference existed in median LOS (median 15 days, range 9-22 days, P<.001) across centers. Median postoperative ICU stay varied from 0 to 7 days (median 4 days, P<.001). Overall, 30-day readmission rate was 55% (31.3%-100%, P<.001). One-year graft failure varied from 0% to 19.1%, with an overall rate of 5.5% (P=.279). One-year patient mortality for all centers was 2.3% (range 0%-11.1%, P=.016). Higher total cost did not correlate with lower readmission rates, patient mortality, graft failure, or any other variable. These data suggest that identifying practice patterns at low-cost centers and implementing them at higher-cost centers may decrease the cost of pediatric liver transplantation without compromising outcomes.
