MBSF mortality denominator

The MBSF mortality denominator can be used to study mortality rates of the elder population in the US. Access to CMS data is restricted. Processed datasets cannot be shared. Contact the authors if you've purchased CMS data through RESDAC and would like to use our data processing pipelines to clean CMS raw data and generate the MBSF mortality denominator. Medicare Overview In the United States, when individuals reach the age of 65, they become eligible for the Medicare federal health insurance program. Medicare also covers individuals under 65 if they have certain disabilities or End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS). About CMS The Center for Medicare & Medicaid Services (CMS) is the federal agency responsible for managing the Medicare and Medicaid data. CMS makes predefined datasets available for purchase to researchers after they enter a Data usage agreement through Research Data Assistance Center (ResDAC). Master Beneficiary Summary File (MBSF) A beneficiary-level data from CMS/ResDAC is known as the Master Beneficiary Summary File (MBSF). The raw MBSF data contains basic demographic information of individuals, an indicator of death, and some details on their medicare enrollment. Mortality Denominator We refer to the mortality denominator as the clean subset of MBSF health data that is representative of the older population. The subset consists of the US elder population; notably, individuals under 64 who qualified because of a disability are excluded.MBSF死亡率分母数据集可用于研究美国老年人群的死亡率。美国医疗保险与医疗补助服务中心（Center for Medicare & Medicaid Services，CMS）的数据获取权限受到严格限制，且处理后的数据集无法公开共享。若您已通过研究数据援助中心（Research Data Assistance Center，ResDAC）购买了CMS原始数据，并希望使用本研究团队的数据处理流程对CMS原始数据进行清洗并生成MBSF死亡率分母数据集，请与本文作者联系。 医疗保险概述 在美国，年满65周岁的个人即可申请加入联邦医疗保险（Medicare）计划。此外，65岁以下的个体若存在特定残疾、终末期肾病（End-Stage Renal Disease，ESRD）或肌萎缩侧索硬化症（Amyotrophic Lateral Sclerosis，ALS），也可纳入医保覆盖范围。 关于CMS 医疗保险与医疗补助服务中心（CMS）是负责管理联邦医疗保险和医疗补助数据的联邦机构。研究人员通过研究数据援助中心（ResDAC）签署数据使用协议后，即可购买CMS预设的数据集。 主受益人摘要文件（Master Beneficiary Summary File，MBSF） CMS/ResDAC提供的受益人级数据即为主受益人摘要文件（MBSF）。原始MBSF数据包含个体的基本人口统计学信息、死亡标识以及部分医疗保险参保相关详情。 死亡率分母 本研究将死亡率分母定义为具有老年人群代表性的经清洗MBSF健康数据子集。该子集覆盖美国老年人群，值得注意的是，因残疾符合参保条件的64岁以下个体被排除在外。
