To describe the performance of Charlson Comorbidity Index (CCI) specifications among Medicare beneficiaries and subgroups.
Medicare data for beneficiaries covered by Parts A and B and not Medicare Advantage throughout 2007.
We evaluated several CCI specifications, particularly a model using expenditures related to Charlson categories, to predict 1 year mortality.
DATA COLLECTION/EXTRACTION METHODS: Data were obtained from the Chronic Condition Data Warehouse.
The use of Charlson related expenditures did not result in improved mortality prediction. CCI models perform less well in population subgroups with higher underlying mortality risks based on age and chronic conditions.
Relatively simple models provide quite adequate discrimination compared to more sophisticated models. Our proposed and more sophisticated model, which added in expenditure information, did not perform as well as much more easily executed methods.
描述医疗保险受益人及亚组中查尔森合并症指数（CCI）规范的表现。
2007年全年参加医疗保险A部分和B部分且未参加医疗保险优势计划的受益人的医疗保险数据。
我们评估了几种CCI规范，特别是使用与查尔森类别相关支出的模型，以预测1年死亡率。
数据收集/提取方法：数据来自慢性病数据仓库。
使用与查尔森相关的支出并未改善死亡率预测。基于年龄和慢性病，CCI模型在潜在死亡风险较高的人群亚组中表现较差。
与更复杂的模型相比，相对简单的模型提供了足够的区分度。我们提出的更复杂的模型，即加入了支出信息的模型，表现不如更容易执行的方法。
