Variation in Home Health Care Use by Dementia Status among a National Cohort of Older Adults

Abstract

Abstract Background Medicare-funded Home Health Care (HHC) delivers skilled nursing, therapy, and related services through visits to the patient’s home. Nearly one-third (31%) of HHC patients have diagnosed dementia, but little is currently known regarding how HHC utilization and care delivery differs for Persons Living with Dementia (PLwD). Methods We drew on linked 2012-2018 Health and Retirement Study and Medicare claims for a national cohort of 1,940 community-living older adults. We described differences in HHC admission, length of stay, and referral source by patient dementia status and used weighted, multivariable logistic and negative binomial models to estimate the relationship between dementia and HHC visit type and intensity while adjusting for sociodemographic characteristics, health and functional status, and geographic/community factors. Results PLwD had twice the odds of using HHC during a two-year observation period, compared to those without dementia (OR: 2.03; p<0.001). They were more likely to be referred to HHC without a preceding hospitalization (49.4% vs 32.1%; p<0.001) and incurred a greater number of HHC episodes (1.4 vs 1.0; p<0.001) and a longer median HHC length of stay (55.8 days vs 40.0 days; p<0.001). Among post-acute HHC patients, PLwD had twice the odds of receiving social work services (aOR: 2.15; p=0.008) and three times the odds of receiving speech-language pathology services (aOR: 2.92; p=0.002). Conclusions Findings highlight HHC’s importance as a care setting for community-living PLwD and indicate the need to identify care delivery patterns associated with positive outcomes for PLwD and design tailored HHC clinical pathways for this patient subpopulation.
