背景与目的：ICD-9-CM对Charlson合并症评分的调整是卫生服务研究人员的宝贵资源。随着全球向ICD-10编码的过渡，根据澳大利亚维多利亚州基于人群的医院数据，开发并验证了Deyo的ICD-10版本。方法：分多步将ICD-9-CM算法翻译为ICD-10-AM （Australian modification）。在使用映射算法开发初始翻译后，这些代码由编码专家和普通医生手动检查面部有效性。由于ICD-10系统是针对国家的，我们的目标是将许多翻译后的代码保持在三位数水平，以便新索引的通用性。结果：两种版本的Charlson指数分布差异不大。指数得分增加与死亡率之间存在很强的相关性：去年使用ICD-9-CM版本的ROC曲线下面积为0.865，而ICD-10版本的ROC曲线下面积仍然很高，为0.855。结论：本研究首次将Charlson合并症指数应用于ICD-10数据。与一种完善的ICD-9-CM编码算法相比，它根据合并症类别得出了非常相似的患病率和预后信息。(C) 2004爱思唯尔公司版权所有。
Background and objective: The ICD-9-CM adaptation of the Charlson comorbidity score has been a valuable resource for health services researchers. With the transition into ICD-10 coding worldwide, an ICD-10 version of the Deyo adaptation was developed and validated using population-based hospital data from Victoria, Australia.Methods: The algorithm was translated from ICD-9-CM into ICD-10-AM (Australian modification) in a multistep process. After a mapping algorithm was used to develop an initial translation, these codes were manually examined by the coding experts and a general physician for face validity. Because the ICD-10 system is country specific, Our goal was to keep many of the translated code at the three-digit level for generalizability of the new index.Results: There appears to be little difference in the distribution of the Charlson Index score between the two versions. A strong association between increasing index scores and mortality exists: the area under the ROC curve is 0.865 for the last year using the ICD-9-CM version and remains high, at 0.855, for the ICD-10 version.Conclusion: This work represents the first rigorous adaptation of the Charlson comorbidity index for use with ICD-10 data. In comparison with a well-established ICD-9-CM coding algorithm, it yields closely similar prevalence and prognosis information by comorbidity category. (C) 2004 Elsevier Inc. All rights reserved.
