Measuring Alzheimer's Disease and Other Dementias in Diverse Populations Using Medicare Claims Data.

ABSTRACT: We examined how methods used for identifying dementia in administrative claims affected dementia incidence across racial/ethnic populations using a 100% sample of Medicare beneficiaries (n?=?23,793,452). We found levels differed by method from 3.1% annual incidence to 3.6% in 2014. Dementia incidence declined from 2007 to 2014, but choice of method differentially impacted levels and trends by race/ethnicity. Methods using codes for dementia diagnosis and drugs to treat symptoms identified proportionally more Hispanics and Asians with dementia than other race/ethnicities, while codes for dementia diagnosis, drugs, and symptoms identified proportionally more whites and American Indians/Alaska Natives with dementia than other race/ethnicities.

Project description:BackgroundThe Medicare Advantage (MA) program is rapidly growing. Limited evidence exists about the care experiences of MA beneficiaries with Alzheimer's Disease and Related Dementia (ADRD). Our objective was to compare care experiences for MA beneficiaries with and without ADRD.MethodsWe examined MA beneficiaries who completed the Medicare Advantage Consumer Assessment of Healthcare Providers and Systems (CAHPS) and used inpatient, nursing home, or home health services in the past 3 years. We classified beneficiaries with ADRD using the presence of diagnosis codes in hospitals, nursing homes, and home health records. Our key measures included overall ratings of care and health plan, and indices of receiving timely care, care coordination, receiving needed care, and customer service. We compared differences between beneficiaries with and without ADRD using regression analysis adjusting for demographic, health, and plan characteristics, and stratifying by proxy response status.ResultsAmong beneficiaries sampled by CAHPS, 22.2% with ADRD completed the survey compared to 38.5% without ADRD. Among proxy responses, beneficiaries with ADRD were 4.2 (95% CI: 0.1-8.4) percentage points less likely to report a high score for receiving needed care, and 3.5 percentage points (95% CI: 0.2-6.9) less likely to report a high score for customer service. Among non-proxy responses, those with ADRD were 9.0 (95% CI: 5.5-12.5) percentage points less likely to report a high score for needed care, and 8.5 (95% CI: 5.4-11.5) percentage points less likely to report a high score for customer service.ConclusionsADRD respondents to the CAHPS were more likely to be excluded from CAHPS performance measures because they did not meet eligibility requirements and rates of non-response were higher. Among responders with or without a proxy, MA enrollees with an ADRD diagnosis reported worse care experiences in receiving needed care and in customer service than those without an ADRD diagnosis.
