描述择期腹主动脉瘤(AAA)修补术后,与院内死亡相关的因素。对全国住院病人样本数据库进行回顾性分析(2007年1月到2011年12月),审查包括所有择期开放性AAA修复(OAR)或血管内AAA修复(EVAR)的患者,分析在2014年12月到2015年1月进行。调整了先前定义的病人和医院水平的危险因素后,使用多变量分析OAR和EVAR患者住院死亡率相关的因素。在1207家医院进行了166 443次手

描述择期腹主动脉瘤(AAA)修补术后,与院内死亡相关的因素。

对全国住院病人样本数据库进行回顾性分析(2007年1月到2011年12月),审查包括所有择期开放性AAA修复(OAR)或血管内AAA修复(EVAR)的患者,分析在2014年12月到2015年1月进行。

调整了先前定义的病人和医院水平的危险因素后,使用多变量分析OAR和EVAR患者住院死亡率相关的因素。

在1207家医院进行了166 443次手术(131 908 EVARs和34 535 OARs),133 407例(80.2%)是男性,123 522例(89.6 %)是白人,平均(SD)73 (0.04)岁。EVAR和OAR的总住院死亡率分别为0.7%和3.8%。一般手术死亡率高的医院,EVAR术后的死亡率也高(死亡率四分位数 ≥ 50%;OR, 1.37; 95% CI, 1.01-1.86; P = 0.04),符合AAA修复术Leapfrog标准的医院间死亡率没有差异(OR, 0.64; 95% CI, 0.38-1.09; P = 0.09)。开放性修补术至少占总AAA修复术25%的医院,OAR术后住院死亡率显著更低(OR, 0.68; 95% CI, 0.52-0.88; P =0 .004)。不管是医院床位尺寸还是教学地位,均与EVAR或OAR术后的死亡率无关。总的来说,OAR (OR, 6.07; 95% CI, 4.92-7.49)和内在患者风险(医疗保险评分; OR, 4.81; 95% CI, 3.45-6.72)是与AAA修复术后院内死亡率最相关的因素,虽然一般手术效果较差的医院(OR, 1.31; 95% CI, 1.06-1.63),开放性修复术至少占25%(OR, 1.39; 95% CI, 1.10-1.75)也与死亡率有关(all P <0 .002)。值得注意的是,开放性修复术至少占25%的机构比例从2007年的41%下降到2011年的18%(P <0 .001)。

患者水平的因素与择期AAA维修术后的住院死亡率相关。医院的病例量和实践模式也与之相关联。这表明适当的OAR经验是重要的。
