Objective.本研究的目的是评价血液透析患者的通路通畅性和翻修率，并确定不同类型患者亚组之间通路性能的差异。该研究使用了来自美国肾脏数据系统透析发病率和死亡率研究第2波的数据，其中包括1996年和1997年初开始透析的透析患者的随机样本。采用考克斯比例风险回归模型和Poisson回归模型对2247例新置透析通路的失败和翻修进行了评估。采用Kaplan-Meier方法估计一期和二期通畅率。1574例人工血管移植物、492例单纯自体瘘和181例静脉转位瘘可用于评价。与单纯瘘管相比，人工移植的原发性失败风险高41%（相对风险，1.41; 95%CI，1.22-1.64; P
Objective. The study's aim was to evaluate access patency and incidence of revisions in patients initiating hemodialysis and to determine differences in access performance by type of access among patient subgroups.Methods. The study used data from the United States Renal Data System Dialysis Morbidity and Mortality Study Wave 2, which contained a random sample of dialysis patients initiating dialysis in 1996 and early 1997. Failures and revisions were evaluated among 2247 newly placed hemodialysis accesses by using Cox proportional hazards regression model and Poisson regression. Primary and secondary patency rates were estimated using the Kaplan-Meier method.Results. Fifteen hundred seventy-four prosthetic grafts, 492 simple autogenous fistulas, and 181 venous transposition fistulas were available for evaluation. Prosthetic grafts had a 41% greater risk of primary failure compared with simple fistulas (relative risk, 1.41; 95% CI, 1.22-1.64; P
