疾病诊断相关分组付费背景下带量采购前后冠状动脉支架植入手术患者医用耗材费用分析

Cost analysis of medical consumables for patients undergoing coronary stent implantation surgery before and after volume procurement in the context of diagnosis related groups payment

目的:研究分析冠状动脉支架集采前后患者相关费用与支架等类别耗材使用变化。方法:收集2019年12月至2021年10月陆军军医大学大坪医院收治的1973例冠状动脉支架植入患者住院医保结算病例数据,依据疾病诊断相关分组(DRG)选取其中的1317例经皮心血管操作及冠状动脉支架植入伴重要或并发症与伴随病的病组患者数据。按照冠状动脉支架集中带量采购前后将其分为集采前组(667例)和集采后组(650例),进行患者医用耗材费用和患者医用耗材用量以及冠状动脉支架等耗材使用对医用耗材费用的影响研究。结果:冠状动脉支架集采对经皮心血管操作及冠状动脉支架植入术患者的住院日和平均支架使用数量无统计学差异。集采前组与集采后组的患者诊疗总费用、医用耗材费用、药品与耗材费用和药品费用比较差异有统计学意义(Z=-22.316、-23.546、-22.917、-5.724,P<0.05);集采前组的患者支架费用[16260(13300,32272)元]、导管导丝球囊鞘耗材数量[5(4,8)套(件)]、导管导丝球囊鞘耗材费用[8719(5805,15372)元]高于集采后组的患者支架费用[1059(590,1770)元]、导管导丝球囊鞘耗材数量[8(7,12)套(件)]、导管导丝球囊鞘耗材费用[5708(3392,12871)元],两组比较差异有统计学意义(Z=-30.452、16.582、-7.670,P<0.05)。集中带量采购前后冠状动脉支架费用和导管导丝球囊鞘费用对患者医用耗材费用均存在相关性(r=0.903、0.473、0.785、0.953,P<0.05);集采后组较集采前组冠状动脉支架费用对患者医用耗材费用影响相关系数下降,导管导丝球囊鞘费用对患者医用耗材费用影响相关系数增加。结论:冠状动脉支架集采对该病组患者有显著的控费效果,且影响医用耗材费用结构,结合DRG改革可不断提高医用耗材临床使用规范性与科学性。

Objective:To study the changes of patient-related costs and the use of stents and other consumables before and after the centralized procurement of coronary stents.Methods:The inpatient medical insurance settlement case data of 1,973 patients with coronary stent implantation admitted to Daping Hospital of Army Medical University from December 2019 to October 2021 were selected.Among them,the data of 1,317 cases of percutaneous cardiovascular surgery and coronary stent implantation with serious or complications and accompanying disease group were slected according to disease diagnosis related groups(DRG),which were divided into the pre-centralized procurement group(667 cases)and the postcentralized procurement group(650 cases)according to the centralized procurement of coronary stents before and after.The costs of patients'medical consumables with the consumption of patients'medical consumables and the impact of the use of consumables such as coronary stents on the costs of medical consumables were compared.Results:There was no significant statistical difference in the hospitalization days and the average number of stents used in patients undergoing percutaneous cardiovascular procedures and coronary stent implantation with centralized procurement of coronary stents.There was a statistically significant difference in the total diagnosis and treatment cost,medical consumables cost,medicines and consumables cost and medicines cost between the pre-centralized procurement group and the post-centralized procurement group(Z=-22.316,-23.546,-22.917,-5.724,P<0.05).The cost of stents[16260(13300,32272)yuan],the number of catheter guidewire balloon sheaths consumables[5(4,8)sets(pieces)],and the cost of catheter guidewire balloon sheaths consumables[8719(5805,15372)yuan]in the pre-collection group were collected.There were statistically significant differences in the stent cost[1059(590,1770)yuan],the number of catheter guidewire balloon sheaths consumables[8(7,12)sets(pieces)],and the cost of catheter guidewire balloon sheaths consumables[5708(3392,12871)yuan]between the two groups(Z=-30.452,16.582,-7.670,P<0.05).There was a statistical correlation between the cost of coronary stents and the cost of catheter guidewire balloon sheaths before and after centralized volume procurement on the cost of medical consumables for patients(r=0.903,0.473,0.785,0.953,P<0.05).The correlation coefficient between the cost of coronary stents and the cost of medical consumables for patients in the post-centralized procurement group decreased compared to the pre-centralized procurement group,the correlation coefficient between the cost of catheter guidewire balloon sheath and the cost of medical consumables for patients increased.Conclusion:The centralized procurement of coronary stents has a significant cost control effect on patients in the disease groups,and affects the cost structure of medical consumables.Combined with DRG reform,it can continuously improve the standardization and scientificity of clinical use of medical consumables.
