Supplementary materials: A real world cost-minimization analysis comparing the use of different endoscopic staplers in video-assisted thoracic surgery lobectomy procedures

These are peer-reviewed supplementary tables for the article 'A real world cost-minimization analysis comparing the use of different endoscopic staplers in video-assisted thoracic surgery lobectomy procedures' published in the Journal of Comparative Effectiveness Research.Supplementary Table 1. Patient baseline characteristics between Type A and Type B groups.Supplementary Table 2. Difference in costs between hypertensive and non-hypertensive patients.Summary: Aim: China’s cost-containment measures increasingly focus solely on the prices of consumable medical supplies without taking a broader perspective on differences in features and overall costs. This study compared two types of endoscopic staplers in video-assisted thoracoscopic surgery (VATS) lobectomy. Materials & methods: Electronic medical records for video-assisted thoracoscopic surgery from 2016 to 2017 were collected from a hospital in Anhui province. Two cohorts were retroactively defined based on stapler type. Total costs were compared using a cost-minimization analysis model. Probabilistic sensitivity analysis was performed. Results: In the base case, the group using more expensive staplers achieved overall cost savings of about $300 per procedure. Sensitivity analysis confirmed this result in 86.5% of cases. Conclusion: A price-only supply selection strategy may have unintended cost consequences.

本数据集为发表于《比较有效性研究杂志》的论文《比较不同内镜缝合器在视频辅助胸腔手术肺叶切除术中的使用成本最小化分析》的同行评审补充表格。补充表格1：A型和B型两组患者的基线特征。补充表格2：高血压患者与非高血压患者之间的成本差异。摘要：研究目的：中国成本控制措施日益集中于仅对消耗性医疗用品的价格进行控制，而未从更广泛的角度考虑功能和总体成本之间的差异。本研究比较了两种类型的内镜缝合器在视频辅助胸腔镜手术（VATS）肺叶切除术中的应用。材料与方法：从2016年至2017年，收集了安徽省一家医院的视频辅助胸腔镜手术电子病历。根据缝合器类型，追溯性地定义了两个队列。使用成本最小化分析模型比较了总成本。进行了概率敏感性分析。结果：在基线情况下，使用更贵缝合器的组每例手术节省了约300美元的总成本。敏感性分析在86.5%的情况下证实了这一结果。结论：仅价格为基础的供应选择策略可能产生未预料的成本后果。
