Supplementary table: Economic burden of complicated ureteral stent removal in patients with kidney stone disease in the USA

These are peer-reviewed supplementary materials for the article 'Economic burden of complicated ureteral stent removal in patients with kidney stone disease in the USA' published in the Journal of Comparative Effectiveness Research.Supplementary Table 1: Patient Characteristics – Propensity-Score MatchingAim: To examine the medical costs of simple versus complicated ureteral stent removal. Materials & methods: We included adults with kidney stones undergoing simple or complicated cystoscopy-based stent removal (CBSR) post ureteroscopy from the 2014 to 2018 Merative™ MarketScan Commercial Database. The medical costs of patients with complicated and simple CBSR were compared. Results: Among 16,682 patients, 2.8% had complicated CBSR. Medical costs for patients with complicated CBSR were higher than for simple CBSR ($2182 [USD] vs $1162; p < 0.0001). Increased stenting time, increased age, southern US geography and encrusted stent diagnoses were significantly associated with complicated CBSR. Conclusion: Complicated ureteral stent removal doubled the medical costs associated with CBSR. Ureteral stents with anti-encrustation qualities may reduce the need for complicated CBSR and associated costs.

本数据集为发表于《比较疗效研究杂志》之文章《美国肾脏结石病患者复杂输尿管支架移除的经济负担》的同行评审补充材料。补充表1：患者特征——倾向得分匹配。目的：比较简单与复杂输尿管支架移除的医疗费用。材料与方法：我们纳入了2014至2018年Merative™ MarketScan商业数据库中接受简单或复杂膀胱镜下支架移除（CBSR）术后输尿管镜检查的成年人。比较了复杂和简单CBSR患者的医疗费用。结果：在16,682名患者中，2.8%接受了复杂CBSR。复杂CBSR患者的医疗费用高于简单CBSR（2182美元[USD] vs 1162美元；p < 0.0001）。支架置入时间延长、年龄增加、美国南部地理分布以及附着性支架诊断与复杂CBSR显著相关。结论：复杂输尿管支架移除使得与CBSR相关的医疗费用翻倍。具有抗附着性的输尿管支架可能降低复杂CBSR及其相关费用的需求。
