In this project we will examine the temporal trajectories of Medicare Part A and B files, which contain records on individual episodes of service use, will be fully linked for the period 1982 to 2002 to the 1982, 1984, 1989, 1884, and 1999 NLTCS screening, community, and institutional interview records. Revisions of the Medicare computer files and data systems increased the information they provide about specific Medicare treatments and diagnoses over time. In part this is due to an improvement in the information content and structure of the databases and, in part, it is due to changes in medical practice and diagnostic precision. What is common to all years of Medicare data is that the exact dates, durations, and amounts of services consumed and expenditures made through Medicare are available on those files for each person in the NLTCS sample for each day in the entire time period 1982 to 2002. Thus, the Medicare records for individuals can be accumulated over the time, age, gender, and other demographic domains as needed to be related to the functional status and health changes manifest in the NLTCS interview data. The Medicare service use data for individuals will be examined for groups of individuals, both at a basic level for commonly (in the literature) used disability categories (e.g., 1-2, 3-4, 5-6 ADLs impaired), and by using objective scaling procedures to transform batteries of multiple survey measures into a small number of disability or health scores. Once the Medicare data are recorded over time and related to survey data, it will be possible to also look for evidence of period effects related to changes in the Medicare Program or in the availability of new types of therapies and diagnostic mechanisms for the elderly (65+) and oldest old (85+) populations and demographic subgroups.

在本项目中，我们将检查 Medicare A 部分和 B 部分文件的时间轨迹，其中包含有关服务使用的各个事件的记录，将 1982 年至 2002 年期间与 1982 年、1984 年、1989 年、1884 年和 1999 年 NLTCS 完全链接起来筛选、社区和机构访谈记录。随着时间的推移，医疗保险计算机文件和数据系统的修订增加了它们提供的有关特定医疗保险治疗和诊断的信息。这部分是由于数据库信息内容和结构的改进，部分是由于医疗实践和诊断精度的变化。 所有年份的 Medicare 数据的共同点是，在 NLTCS 样本中的每个人在 1982 年至 2002 年整个时间段内每一天的确切日期、持续时间以及通过 Medicare 消费的服务和支出的金额都可以在这些文件中找到因此，可以根据需要在时间、年龄、性别和其他人口统计领域累积个人的医疗保险记录，以与 NLTCS 访谈数据中显示的功能状态和健康变化相关。个人医疗保险服务使用数据将针对个人群体进行检查，既针对常用（文献中）使用的残疾类别（例如，1-2、3-4、5-6 ADL 受损）的基本水平，又针对个人群体进行检查。使用客观缩放程序将多种调查措施的组合转化为少量的残疾或健康评分。一旦随着时间的推移记录了医疗保险数据并与调查数据相关联，就有可能寻找与医疗保险计划的变化或针对老年人的新型疗法和诊断机制的可用性相关的时期效应的证据（65 +) 和最年长的老年人 (85 岁以上) 人口和人口亚群。
