Abstract
BACKGROUND: Hispanic older adults are a high-risk population for Alzheimer's disease and related dementias (ADRD) but are less likely than non-Hispanic White older adults to have ADRD documented as a cause of death on a death certificate. OBJECTIVE: To investigate characteristics associated with ADRD as a cause of death among Mexican-American decedents diagnosed with ADRD. METHODS: Data came from the Hispanic Established Populations for the Epidemiologic Study of the Elderly, Medicare claims, and National Death Index. RESULTS: The final sample included 853 decedents diagnosed with ADRD of which 242 had ADRD documented as a cause of death. More health comorbidities (OR = 0.40, 95% CI = 0.28-0.58), older age at death (OR = 1.18, 95% CI = 1.03-1.36), and longer ADRD duration (OR = 1.08, 95% CI = 1.03-1.14) were associated with ADRD as a cause of death. In the last year of life, any ER admission without a hospitalization (OR = 0.45, 95% CI = 0.22-0.92), more physician visits (OR = 0.96, 95% CI = 0.93-0.98), and seeing a medical specialist (OR = 0.46, 95% CI = 0.29-0.75) were associated with lower odds for ADRD as a cause of death. In the last 30 days of life, any hospitalization with an ICU stay (OR = 0.55, 95% CI = 0.36-0.82) and ER admission with a hospitalization (OR = 0.67, 95% CI = 0.48-0.94) were associated with lower odds for ADRD as a cause of death. Receiving hospice care in the last 30 days of life was associated with 1.98 (95% CI = 1.37-2.87) higher odds for ADRD as a cause of death. CONCLUSION: Under-documentation of ADRD as a cause of death may reflect an underestimation of resource needs for Mexican-Americans with ADRD.
