Implementation of the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Canada (ICD-10-CA) and the Canadian Classification of Interventions (CCI) coding system presents challenges for using Canadian administrative data. Thus, a multi-step process was conducted to develop ICD-10-CA/CCI coding algorithms to define nine comorbidities and three procedures. These clinical variables have been used in ICD-9-CM data for risk adjustment in assessment of outcomes after aortic and mitral valve replacement surgery. Among patients included in the ICD-9-CM data during 1999 and 2001 and in the ICD-10-CA/CCI data during 2002 and 2003 in a Canadian Health Region, frequencies of the nine comorbidities and the three procedures remained generally similar across databases. The newly developed ICD-10-CA/CCI and previous ICD-9-CM coding algorithms are comparable in detecting these clinical variables. However, performance of ICD-10-CA/CCI coding algorithms in risk adjustment should be evaluated in a larger database.
实施《国际疾病和相关健康问题统计分类第十次修订本，加拿大》（ICD - 10 - CA）和加拿大干预措施分类（CCI）编码系统给使用加拿大行政数据带来了挑战。因此，开展了一个多步骤过程来开发ICD - 10 - CA/CCI编码算法，以定义九种合并症和三种手术。这些临床变量已用于ICD - 9 - CM数据中，用于主动脉和二尖瓣置换手术后结局评估的风险调整。在加拿大一个卫生区域，1999年至2001年纳入ICD - 9 - CM数据以及2002年至2003年纳入ICD - 10 - CA/CCI数据的患者中，九种合并症和三种手术的频率在各数据库中总体上保持相似。新开发的ICD - 10 - CA/CCI和先前的ICD - 9 - CM编码算法在检测这些临床变量方面具有可比性。然而，ICD - 10 - CA/CCI编码算法在风险调整中的性能应在更大的数据库中进行评估。
