CORE--DATA ACQUISITION

计划项目汇集了也许是最好的 曾经存在过的医学数据。数据核心的目标是 更新这些文件并获取所需的新数据资源 继续进行计划项目研究。许多数据资源 将在计划项目中使用，并公开提供 通过行政核心进行例行管理。三个数据集， 然而，涉及特殊的收购安排和补充 成本。数据核心的具体目标是：(1)维护我们的 现有的纵向Medicare数据文件，用来更新这些文件 更新的联邦医疗保险数据，因为它是可用的，并开发链接 大样本美国老年人的全面医疗补助数据。(2) 维护我们现有的纵向MedSTAT数据文件，并获得 来自MedSTAT的更新和扩展数据，用于医疗保健成本分析 在大公司。(3)取得全面的出院纪录 加利福尼亚州、佛罗里达州、马萨诸塞州、新泽西州和纽约州。

The Program Project has put together perhaps the best resource file of medical data that has ever existed. The goal of the data core is to update these files and to acquire the new data resources necessary for continuing Program Project research. Many of the data resources that will be used in the Program Project are publicly available, and are managed routinely through the administrative core. Three data sets, however, involve special acquisition arrangements and supplementary costs. The specific aims of the data core are: (1) To maintain our existing longitudinal Medicare data files, to update these files with more recent Medicare data as it becomes available, and to develop linked comprehensive Medicaid data for a large sample of older Americans. (2) To maintain our existing longitudinal Medstat data files, and to obtain updated and expanded data from Medstat for analyses of health care costs in large firms. (3) To acquire comprehensive hospital discharge records for California, Florida, Massachusetts, New Jersey and New York.
