Objective
To estimate the cost of rescue and cost of failure and determine cost-effectiveness of rescue from major complications at high-volume (HV) and low-volume (LV) centers
Methods
Ninety-six thousand one hundred seven patients undergoing liver resection were identified from the Nationwide Inpatient Sample (NIS) between 2002 and 2011. The incremental cost of rescue and cost of FTR were calculated. Using propensity-matched cohorts, a cost-effectiveness analysis was performed to determine the incremental cost-effectiveness ratio (ICER) between HV and LV hospitals.
Results
Ninety-six thousand one hundred seven patients were identified in NIS. The overall mortality was 2.3% and was lowest in HV centers (HV 1.4% vs. MV 2.1% vs. LV 2.6%; p < 0.001). Major complications occurred in 14.9% of hepatectomies and were comparable regardless of volume (HV 14.2% vs. MV 14.3% vs. LV 15.4%; p < 0.001). The FTR rate was substantially lower among HV centers (HV 7.7%, MV 11%, LV 12%; p < 0.001). At a willingness to pay benchmark of $50,000 per year of life saved, both HV (ICER = $3296) and MV (ICER = $4182) centers were cost-effective at rescuing patients from a major complication compared to LV hospitals.
Conclusion
Not only was FTR less common at HV hospitals, but the management of most major complications was cost-effective at higher volume centers.
