Economic impact of powered stapler in video-assisted thoracic surgery lobectomy for lung Cancer in a Chinese tertiary hospital: a cost-minimization analysis

Abstract

Abstract Background To assess the economic impact of powered stapler use in video-assisted thoracic surgery (VATS) lobectomy for lung cancer in a Chinese tertiary care hospital. Methods This study identified 388 patients who received VATS lobectomy using the ECHELON powered stapler (n = 296) or the ECHELON manual stapler (n = 92) for lung cancer in a Chinese tertiary hospital. Multiple generalized linear regression analyses were conducted using data on hospital costs and patient characteristics to develop predictive equations for hospital costs in a cost-minimization analysis (CMA) model comparing hospital costs associated with the ECHELON powered stapler and the ECHELON manual stapler. CMA model was used to conduct scenario analysis to compare the ECHELON powered stapler with another manual stapler (Victor Medical). Results The multiple generalized linear regression analyses identified that using the ECHELON powered stapler in VATS lobectomy for lung cancer was associated with significantly lower drug costs than using the ECHELON manual stapler (coefficient − 0.256, 95% confidence interval: − 0.375 to − 0.139). The CMA model estimated that the ECHELON powered stapler could save hospital costs by ¥1653 when compared with the ECHELON manual stapler (¥65,531 vs. ¥67,184). The use of the ECHELON powered stapler also saved hospital costs by ¥4411 when compared with the Victor Medical manual stapler (¥65,531 vs. ¥69,942) in the scenario analysis. Conclusions Compared to the two manual staplers used for VATS lobectomy for lung cancer in a Chinese tertiary hospital, the ECHELON powered stapler had 100% probability to save total hospital costs under present prices of the three staplers according to the CMA.
