Prevalence and predictors of incident ADRD diagnosis following a Medicare home health episode.

Abstract

Home health (HH) may be an important source of care for those with early-stage/undiagnosed Alzheimer's Disease and Related Dementias (ADRD), but little is known regarding prevalence or predictors of incident ADRD diagnosis following HH. Using 2010-2012 linked Master Beneficiary Summary File (MBSF) and HH assessment data for 40,596 Medicare HH patients, we model incident ADRD diagnosis within 1 year of HH via multivariable logistic regression. Among HH patients without diagnosed ADRD, 10% received an incident diagnosis within 1 year. In adjusted models, patients were three times more likely to receive an incident ADRD diagnosis if they had HH clinician-reported impaired overall cognition (compared to patients without reported impairment) and twice as likely if they were community-referred (compared to hospital-referred patients). There is a pressing need to develop tailored HH clinical pathways and protect access to community-referred HH to support community-living older adults with early-stage/undiagnosed ADRD.
