Trends in detection of dementia among beneficiaries in Medicare advantage and traditional Medicare
By Qian Y, Allore H and Chen X.
Abstract
Introduction
Timely dementia detection is critical for care planning and supportive services, yet whether claims-based detection has improved over time remains unknown.
Methods
This retrospective cohort study used Health and Retirement Study (HRS) survey data linked to Medicare claims (1998 to 2020). Persons with probable dementia (PWPD) were identified using the Langa-Weir algorithm. Covariate-adjusted logistic regression with predictive margins estimated the proportions of PWPD receiving a claims-based dementia diagnosis, overall and among early-stage PWPD.
