Findings from U.S. Food and Drug Administration (FDA) Broaden Understanding of Managed Care [Comparing the Centers for Medicare and Medicaid Services (Cms) Enrollment Data Death Dates To the National Death Index (Ndi)]: Managed Care

2024 APR 01 (NewsRx) -- By a News Reporter-Staff News Editor at Health Policy and Law Daily -- Investigators discuss new findings in Managed Care. According to news reporting out of Silver Spring, Maryland, by NewsRx editors, research stated, “In the United States, the National Death Index (NDI) is the most complete source of death information, while epidemiologic studies with mortality outcomes often rely on U.S. Medicare data for outcome ascertainment.”

Financial support for this research came from U.S. Food and Drug Administration, through an inter-agency agreement with the Centers for Medicare & Medicaid Services.

Our news journalists obtained a quote from the research from U.S. Food and Drug Administration (FDA), “The purpose of this study was to assess the agreement of death information between the Centers for Medicare & Medicaid Services (CMS) Medicare enrolment data and NDI. Using Medicare and NDI data from 1999 through 2016, we identified Medicare beneficiaries who were reported dead in the CMS Medicare enrolment database (EDB) and Common Medicare Environment (CME), linked these beneficiaries to the NDI using CMS Health Insurance Claim number, and compared death dates between the two data sources. To assess agreement between our data sources, we calculated kappa scores; where a kappa of 1 indicates perfect agreement and a kappa of 0 indicates agreement equivalent to chance. We also examined CMS to NDI linkage and death date matching for stability over time. Of the 36 785 640, Medicare beneficiaries reported dead in CMS enrollment data from 1999 to 2016, 97.5% were linked to the NDI. A kappa score of 0.98 showed a near perfect agreement between NDI and CMS reported deaths. The percentage of linked cases exactly matching on death dates increased from 94.8% in 1999 to 99.4% in 2016.”

According to the news editors, the research concluded: “Our findings suggest strong concordance between death dates as recorded by CMS enrollment data and the NDI in the entire Medicare population.”
