Cornell PY, Zhang W, Smith L, Rahman M, Grabowski DC, Carder P, Thomas KS. Memory care reduces nursing home admissions among assisted-living residents with dementia. Alzheimer's & dementia : the journal of the Alzheimer's Association. 2022 Oct 1; 18(10):1880-1888.
INTRODUCTION: We compare nursing-home and hospital admissions among residents with Alzheimer''s disease and related dementias (ADRD) in memory-care assisted living to those in general assisted living. METHODS: Retrospective study of Medicare beneficiaries with ADRD in large ( > 25 bed) assisted-living communities. We compared admission to a hospital, to a nursing home, and long-term ( > 90 day) admission to a nursing home between the two groups, using risk differences and survival analysis. RESULTS: Residents in memory-care assisted living had a lower adjusted risk of hospitalization (risk difference = -1.8 percentage points [P = .014], hazard ratio = 0.93 [0.87-1.00]), a lower risk of nursing-home admission (risk difference = -2.2 percentage points [P < .001], hazard ratio = 0.87 [-.79-0.95]), and a lower risk of a long-term nursing home admission (risk difference = -1.1 percentage points [P < .001], hazard ratio = 0.71 [0.57-0.88]). DISCUSSION: Memory care is associated with reduced rates of nursing-home placement, particularly long-term stays, compared to general assisted living.
