Extreme Heat and Hospitalization Among Older Persons With Alzheimer Disease and Related Dementias.

ABSTRACT:

Importance

As US society ages and the climate changes, extreme outdoor heat may exacerbate the health burden of Alzheimer disease and related dementias (ADRD), but where, when, and among whom extreme heat may increase hospitalizations with ADRD remains understudied.

Objective

To investigate the association between extreme heat and the risk of hospitalization with ADRD, and to explore how associations differ across climates and population subgroups.

Design, setting, and participants

Population-based cohort study, using a time-stratified case-crossover design, of Medicare fee-for-service (Part A) claims from 2000 to 2018 among beneficiaries aged 65 years or older in the contiguous US; time-stratified case-crossover design implemented with distributed lag nonlinear model
