Background: Objectives were to determine the causes of readmission and assess the cost-effectiveness of high (HQ) and low quality (LQ) hospitals in performing pancreatic resection, by using readmission rates as the measure of quality.
Methods: We identified 53,572 pancreatic resection cases from National Readmission Database from 2010 through 2014. Hospitals were risk adjusted and ranked based on readmission. Top 20% HQ hospitals having the lowest readmission rates were compared to the bottom 20% LQ hospitals with the highest readmission rates.
Results: The 90-day readmission rate was 27.2% (HQ: 25.7%, LQ: 30.9%, p < 0.001). Compared to LQ, HQ hospitals had lower mortality (2.1% vs 10.2%, p < 0.001) and major complication (10.5% vs 53%, p < 0.001). Major complication during index operation was a major predictor of readmission (RR: 1.6, 95% CI: 1.6-1.7, p < 0.001). The optimal cut point of hospital volume associated with low mortality was 70 or more cases/year. Per year of survival benefit at HQ hospitals, the costs were lower by $9,293 with cost-savings of $6.98 million/year.
Conclusion: HQ hospitals were cost-effective at performing pancreatic resection and achieved substantial cost-savings by avoiding major complications during index operation and having lower rates of readmissions. Hospital readmission rate is a strong marker of quality of care.
