摘要为了使用MED-ECHO数据库（魁北克）测量共病疾病的负担，将所谓的Charlson指数改编为国际疾病分类（ICD-9）代码。由此产生的合并症指数被应用于一组62,456例患有以下疾病之一的住院死亡患者的研究：缺血性心脏病，充血性心力衰竭，中风或细菌性肺炎。采用多元逻辑回归分析住院死亡与其预测因素的关系，包括性别、主要诊断、年龄和合并症指数。对合并症评分进行各种转换，并评估其对预测准确性的影响。合并症指数始终与死亡密切相关。当考虑性别、年龄、合并症和主要诊断时，受试者工作曲线下面积为0.83。因此，查尔森指数是一个有用的方法，风险调整的结果研究，从行政数据库。
Abstract To measure the burden of comorbid diseases using the MED-ECHO database (Quebec), the so-called Charlson index was adapted to International Classification of Disease (ICD-9) codes. The resulting comorbidity index was applied to the study of inpatient death in a group of 62,456 patients having one of the following conditions: ischemic heart disease, congestive heart failure, stroke, or bacterial pneumonia. Multiple logistic regression was used to relate inpatient death to its predictors, including gender, principal diagnosis, age, and the comorbidity index. Various transformations of the comorbidity score were performed, and their effect on predictive accuracy was assessed. The comorbidity index was constantly and strongly associated with death. When gender, age, comorbidity and the principal diagnoses were taken into account, the area under the receiver-operating curve was 0.83. Therefore, the Charlson Index is a useful approach to risk adjustment in outcomes research from administrative databases.
