Table_1_The cost of total hip arthroplasty: compare the hospitalization costs of national centralized procurement and national volume-based procurement.docx

BackgroundWith the increasing demand for joint replacement surgery in China, the government has successively issued the policies of national centralized procurement (NCP) and national volume-based procurement (NVBP) of artificial joints. The purpose of this study is to evaluate the impact of NCP and NVBP policies on hospitalization cost, rehospitalization and reoperation rate of total hip arthroplasty (THA).MethodsIn total, 347 patients who underwent THA from January 2019 to September 2022 were retrospectively analyzed. According to the implementation of NCP and NVBP, patients were divided into three groups: control group (n = 147), NCP group (n = 130), and NVBP group (n = 70). Patient-level data on the total hospitalization costs, rehospitalization rate, THA reoperation rate and inpatient component costs were collected before and after the implementation of the policies and Consumer Price Index was used to standardize the cost.ResultsAfter the implementation of NCP and NVBP, the total cost of hospitalization decreased by $817.41 and $3950.60 (p

随着中国对人工关节置换手术需求的不断增长，我国政府相继出台了国家集中采购（NCP）和国家按量采购（NVBP）人工关节的政策。本研究旨在评估NCP和NVBP政策对全髋关节置换术（THA）住院费用、再住院率和再次手术率的影响。研究方法：对2019年1月至2022年9月期间接受THA手术的347名患者进行回顾性分析。根据NCP和NVBP的实施情况，将患者分为三组：对照组（n=147）、NCP组（n=130）和NVBP组（n=70）。收集了政策实施前后患者层面的总住院费用、再住院率、THA再次手术率和住院组成部分费用，并使用消费者价格指数对成本进行标准化。结果：NCP和NVBP政策实施后，住院总费用分别下降了817.41美元和3950.60美元（p
