PURPOSE
To determine the positive predictive values (PPV) of Ontario administrative data codes for the identification of open (OSR) and endovascular (EVAR) repairs of elective (eAAA) and ruptured (rAAA) abdominal aortic aneurysms.
METHODS
We randomly identified 319 eAAA and rAAA repairs at two Toronto hospitals between April 2003 and March 2015, using administrative health data in Ontario, Canada. International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) codes I71.3 and I71.4, were used to identify rAAA and eAAA patients, respectively. A blinded retrospective chart review was conducted and served as the gold standard comparator. Re-abstracted records were compared to Canadian Classification of Health Interventions (CCI) and Ontario Health Insurance Plan (OHIP) codes in the Canadian Institute for Health Information Discharge Abstract Database (CIHI-DAD) and OHIP databases. We calculated the PPV and 95% confidence intervals (95% CI) of individual and combined procedure and billing codes for elective and ruptured OSR and EVAR (eOSR, eEVAR, rOSR, and rEVAR).
RESULTS
Permutation of codes allowed identification of eOSR with 95% PPV (95% CI 88, 98), eEVAR with 96% PPV (95% CI 90, 99), rOSR with 87% PPV (95% CI 79, 93) and rEVAR with 91% PPV (95% CI 59, 100).
CONCLUSIONS
Diagnostic, procedure and billing code combinations allow identification of eOSR, eEVAR, rOSR and rEVAR patients in Ontario administrative data with a high degree of certainty.
目的
确定安大略省行政数据编码用于识别择期（eAAA）和破裂性（rAAA）腹主动脉瘤开放修复术（OSR）和血管内修复术（EVAR）的阳性预测值（PPV）。
方法
我们利用加拿大安大略省的行政健康数据，在2003年4月至2015年3月期间，从多伦多的两家医院随机识别出319例eAAA和rAAA修复病例。分别使用国际疾病和相关健康问题统计分类第10版（ICD-10）编码I71.3和I71.4来识别rAAA和eAAA患者。进行了一项盲法回顾性病历审查，并将其作为金标准对照。将重新提取的记录与加拿大卫生信息研究所出院摘要数据库（CIHI-DAD）和安大略省医疗保险计划（OHIP）数据库中的加拿大卫生干预分类（CCI）和OHIP编码进行比较。我们计算了择期和破裂性OSR及EVAR（eOSR、eEVAR、rOSR和rEVAR）的个体及组合手术和计费编码的PPV及95%置信区间（95%CI）。
结果
编码排列可识别出eOSR，PPV为95%（95%CI 88, 98），eEVAR的PPV为96%（95%CI 90, 99），rOSR的PPV为87%（95%CI 79, 93），rEVAR的PPV为91%（95%CI 59, 100）。
结论
诊断、手术和计费编码组合能够高度确定地在安大略省行政数据中识别出eOSR、eEVAR、rOSR和rEVAR患者。
