DESCRIPTION (provided by applicant): The proposed study will examine the differences in mortality and the implications for survival estimation in older adults with cancer using data from linked Medicare claim files (Standard Analytic File, Provider of Services file, MEDPAR files, vital status flies), the national survey findings from Asset and Health Dynamics of the Oldest-Old (AHEAD) study and the National Death Index (NDI). The proposed project has three specific aims: 1) to extract cancer cases from Medicare/AHEAD files and link these files with NDI files for one composite data set, 2) to identify and describe various risk factors that are associated with death in a nationally representative sample of older adults with cancer, 3) to conduct preliminary analysis involving differences in mortality risks for older adults across the country. The proposed study can provide a beginning foundation for future testing of demographic multistate models that project the impact of cancers by duration and severity of disease and evaluate the feasibility large-scale comprehensive analysis. Preliminary models will be constructed relating survival to the risk factors identified in the analysis. The data file will provide normative, demographic data from a nationally representative sample and the within-subject changes that occur with regard to physical and. cognitive disability and utilization of both formal and informal support services. This data file will be made publicly available through the World Wide Web (WWW).

描述(由申请人提供)：建议的研究将审查 老年人死亡率的差异及其对生存估计的影响 成人癌症患者使用相关联的Medicare索赔文件中的数据(标准 分析文件、服务提供商文件、MEDPAR文件、重要状态文件)、 全国高龄老人资产与健康动态调查结果 (AHEAD)研究和国家死亡指数(NDI)。拟议中的项目具有 三个具体目标：1)从Medicare/Ahead文件中提取癌症病例和 将这些文件与一个复合数据集的NDI文件链接，2)识别和 描述在全国范围内与死亡有关的各种风险因素 有代表性的老年癌症患者样本，3)进行初步 分析不同地区老年人死亡风险的差异 国家。 建议的研究可以为未来的测试提供初步的基础 按病程预测癌症影响的人口统计多状态模型 和疾病的严重程度，并评估大规模综合的可行性 分析。将建立存活率与风险之间的初步模型。 分析中确定的因素。数据文件将提供规范的、 来自全国代表性样本和受试者内部的人口统计数据 在物理和物理方面发生的变化。认知障碍和 利用正式和非正式支助服务。该数据文件将 通过万维网(WWW)向公众开放。
