我们使用医疗保险数据库和美国人口普查数据来解决对于使用医疗保险文件进行流行病学研究至关重要的两个问题。首先，我们检查了参加医疗保险计划的人口与美国人口普查估计的美国老年居民人口的相似程度。我们发现总人口估计值存在微小差异，但年龄和种族方面存在显着差异。其次，我们发现，在医疗保险参保者中，医生声称发现了一小部分髋部骨折病例，而这些病例在出院档案中没有记录。在美国，这一比例因年龄、地区和州而异。根据 Medicare 出院数据以及可能还有其他出院数据集计算费率时，必须考虑到这些限制。使用所有可用的 Medicare 数据文件可以克服这些限制。
We used Medicare data bases and US Census data to address two questions critical to the use of Medicare files for epidemiologic research. First, we examined the degree to which the population enrolled in the Medicare program is similar to the elderly resident population of the United States, as estimated by the US Census. We found small differences in the total population estimates but substantial differences by age and race. Second, we found that among Medicare enrollees, physician claims identify a small proportion of hip fracture cases which are not documented in the hospital discharge files. This proportion varies by age, region, and state within the United States. Calculation of rates based on Medicare hospital discharge data, and probably other hospital discharge data sets as well, must take these limitations into account. Use of all available Medicare data files can overcome these limitations.
