Area of Science:

  • Public Health
  • Gerontology
  • Data Science

Background:

  • Effective surveillance is crucial for public health planning, resource allocation, and tracking progress in dementia prevention and care.
  • Currently, no comprehensive federal or private system tracks Alzheimer's disease and related dementias (ADRD) in the U.S.

Purpose of the Study:

  • To develop a national-level surveillance system for diagnosed dementia in the U.S.
  • To create a web-based interface utilizing Medicare claims data for dementia surveillance.

Main Methods:

  • Utilized 100% Medicare fee-for-service (FFS) and Medicare Advantage (MA) claims data.
  • Developed a web-based interface, the Dementia DataHub, for national U.S. dementia surveillance.

Main Results:

  • The Dementia DataHub provides 2020 statistics on dementia prevalence, incidence, mortality, and COVID-19 infections.
  • Data is available at national, state, and county levels, with subgroup analyses by demographics and enrollment status.
  • The platform allows bivariate analyses with socioeconomic and healthcare access indicators, with plans to add 2021 data and hospitalization/nursing home placement outcomes.

Conclusions:

  • The Dementia DataHub serves as a vital resource for various organizations addressing the cognitive impairment and dementia epidemic.
  • It supports government, academic, industry, and advocacy efforts in understanding and combating dementia.
