Medicaid Analytic Extract (MAX) Date of Death Auxiliary File, 1999-2008.

摘要

Beginning in 1999, all states and the District of Columbia were required to report Medicaid enrollee eligibility and claims data in a standard format into the Medicaid Statistical Information System (MSIS). Mathematica Policy Research, on behalf of the Centers for Medicare & Medicaid Services (CMS), has produced research files derived from these data for each state by calendar year. These files are known as the Medicaid Analytic eXtract (MAX) files. As the quality of the Medicaid data submitted by the states has improved over the years, they have come to be regarded as among the most important research tools for measuring Medicaid enrollment and understanding patterns of Medicaid service use and expenditures across states and over time. Heightened interest in and expanded funding for comparative effectiveness research (CER) on the Medicaid population has increased the use of MAX data recently. CER researchers often use death as an outcome measure, typically measuring duration until death or including an indicator of death in a time period. To support these analyses, the MAX person-summary (PS) file contains three dates of death: (1) the MSIS date of death, which is reported by the state in the MSIS file; (2) the Medicare Enrollment Database (EDB) date of death, which is linked to the MAX PS file during MAX production (and is available only for people who are dually enrolled in Medicare and Medicaid); and (3) the date of death extracted from the Social Security Administrations (SSA) Death Master File (DMF), which is linked to the MAX PS file during MAX production. All three date of death (DOD) files are right-censored, meaning they contain dates of death that occurred prior to or during the MAX file year (no one in the MAX 2007 PS file, for example, has a date of death after 2007).
