Claims data are an important source of data for public health surveillance but have not been widely used in the United States because of concern with personally identifiable health information and other issues. We describe the development and availability of a new set of public use files created using de-identified health care claims for fee-for-service Medicare beneficiaries, including individuals 65 years and older and individuals with disabilities younger than 65 years, and their application as tools for public health surveillance. We provide an overview of these files and their attributes; a review of beneficiary de-identification procedures and implications for analysis; a summary of advantages and limitations for use of the public use files for surveillance, alone and in combination with other data sources; and discussion and examples of their application for public health surveillance using examples that address chronic conditions monitoring, hospital readmissions, and prevalence and expenditures in diabetes care.
理赔数据是公共卫生监测的重要数据来源，但由于对个人可识别健康信息及其他问题的担忧，在美国尚未得到广泛应用。我们描述了一组新的公共使用文件的开发情况及可用性，这些文件是使用去识别化的医保服务收费医疗理赔数据创建的，涵盖65岁及以上的老年人以及65岁以下的残疾人士，并介绍了其作为公共卫生监测工具的应用。我们概述了这些文件及其属性；回顾了受益人的去识别化程序及其对分析的影响；总结了单独使用以及与其他数据源结合使用这些公共使用文件进行监测的优缺点；并通过涉及慢性病监测、医院再入院以及糖尿病护理的患病率和支出等示例，讨论了其在公共卫生监测中的应用情况。
