Do assisted-living residents Portia Y. Cornell, M.S.P.H., Ph.D. Academy Health ARM in dementia-licensed New Orleans, LA facilities have better June 27, 2017 outcomes? Portia_Cornell@brown.edu
Specialized dementia-care units: licensing requirements Some states issue special license for dementia care Licensing requirements differ by state Secured to prevent wandering Training requirements Staff-to-resident ratios 2
Conceptual model for specialized- care licensing Information asymmetries between prospective resident and assisted-living community Dementia-specialized- care license is a “signal” of underlying capacity and quality of a facility (Spence 1971) Key insight: cost of licensure is lower for higher-quality facilities Limitation: prospective don’t update their beliefs from experience 3
Conceptual model: information asymmetries Prospective resident AL Community Informatio n Observation • • Reputation Licensing • Licensing requirements directly impact patient outcomes License is a signal of deeper specialization & capacity 4
What is the effect of living in a dementia-specialized AL? Does living in a dementia-specialized assisted-living facility, compared to a non-specialized facility, affect resident outcomes and health care use? Outcomes: Mortality Hospice use Emergency department visits Inpatient hospital days 5
Approach Linear model effect of residing in dementia-licensed AL Instrumental variable analysis Stratify by dual status and state 6
Instrument definition Log-distance difference: D1 = distance to nearest non-specialized AL community D2 = distance to nearest dementia-specialized AL community lnDD = ln(D1) – ln(D2) Regular assisted-living Dementia-licensed residence assisted-living residence With increasing lnDD, more likely to move to a dementia- licensed residence D1 D2 D1 D2 lnDD<0 lnDD>0 7

Interpreting Results Dementia-specialized communities increase mortality? Inefficient allocation of resources Value independence and quality of life over safety and prolonging life? Increase use of Medicare hospice benefit suggests different priorities Geographic differences? E.g.: frail individuals may choose assisted living over a nursing-home special-care-unit if there is a dementia-specialized facility nearby 18
Caveats, limitations, and hedges IV addresses patient-level selection, but NOT geographic selection Within a dementia-licensed community with both specialized and non-specialized care, cannot identify who lives in the dementia unit 19
