Centers for Medicare & Medicaid Services

CMS数据，包括医疗保险、医疗补助和长期护理数据(OASIS和MDS)，目前被NIH/NIA的研究人员用来进行许多创新研究，以支持NIH/NIA的任务。例如，医疗保险对服务利用和健康结果的影响，对未来医疗支出的预测，以及对阿尔茨海默病负担的估计等。目前，申请者预算在申请中获取CMS数据的费用，NIH/NIA通过RPG基金(直接和间接费用)向受赠人支付永久获取数据的费用(通常到授权期结束)。费用从几千美元(重复使用)到超过十万美元不等，具体取决于所要求的金额。CMS提出的虚拟数据访问可能是一种向具有各种不同研究需求的大量用户提供数据的有效和安全的方法。

CMS data, which include Medicare, Medicaid, and long-term care data (OASIS and MDS), are currently used by NIH/NIA researchers to conduct many innovative studies in support of the NIH/NIA mission. For example, the impact of Medicare on service utilization and health outcomes, projections of future healthcare expenditures, and estimates of the burden of Alzheimer’s disease, among others. Currently, applicants budget costs to acquire CMS data in the application, and NIH/NIA pays grantees through RPG funds (direct and indirect costs) to acquire the data in perpetuity (usually until the end of the grant period). The cost varies from a few thousand dollars (re-use) to more than one hundred thousand dollars, depending on the amount requested. A virtual data access as proposed by CMS can potentially be an efficient and secure method of providing data to a large number of users, with a variety of different research needs.
