Abstract

Background: Numerous studies have described positive relationships between hospital volume (HV) and clinical outcomes in highly complex procedures, including esophagectomies. Although the centralization of surgery has been considered a possible solution for improving clinical outcomes, the HV impact on perioperative healthcare costs is unknown. This study aimed to determine the relationship between HV and perioperative healthcare costs for patients undergoing esophagectomy for esophageal cancer.

Methods: This retrospective, nationwide cohort study used Japanese Administrative Claims Database data. Data on esophagectomies performed nationwide in 2015 were extracted. The outcome measure was perioperative healthcare costs per person from the perspective of the insurer. The healthcare costs in outpatient or inpatient settings of any hospital and clinic where patients received treatment were summed up from the month the surgery was performed to 3 months after. Linear regression analyses were conducted to assess the risk-adjusted effects of the HV category (1-4/5-9/10-14/15-) on perioperative costs.

Results: A total of 5232 patients underwent an esophagectomy at 584 hospitals. The overall perioperative cost was 20.834 billion Japanese yen (JPY). The median perioperative costs per person for each HV category (1-4/5-9/10-14/15-) were 3.728 (709 patients), 3.740 (658 patients), 3.760 (512 patients), and 3.760 (3253 patients) million JPY, respectively (P = 0.676). Multivariate analyses revealed that each HV category had no significant impact on perioperative costs.

Conclusions: There were no significant differences in the perioperative costs between high- and low-volume centers. Esophageal cancer surgery centralization may be achievable without increasing healthcare costs.
