BACKGROUND: Assisted-living (AL) settings are an important residential care option for old and disabled Americans, but there are no national data characterizing medication use in AL.
OBJECTIVE: To investigate medication costs and use of older adults living in the AL settings compared to those in the community, independent living, and nursing home settings.
DESIGN: 2015 National Health and Aging Trends Study; nationally representative cross-sectional study.
PATICIPANTS: Respondents ≥ 65 years with Medicare Part D prescription drug coverage (n = 5980, representing 32.34 million older adults).
MEASURES: Total Part D medication costs; number of 30-day prescription fills; binary indicators for overall polypharmacy (≥ 5 and ≥ 10 concurrent medications), prescription fills of opioid and psychotropic medications including antipsychotics, benzodiazepines, gabapentinoids, antidepressants, and central nervous system-active (CNS-active) polypharmacy.
RESULTS: Adjusting for demographics, the annual medication costs among AL residents, at $3890, were twice as high as those of their community-dwelling counterparts ($1932; p < .01). All medication outcomes except opioids were higher for older adults in AL compared to community settings. While the adjusted number of 30-day prescription fills among AL residents was slightly lower than that of nursing home residents (89.5 vs. 106.2; p < .05), AL residents experienced equivalent rates of overall polypharmacy ≥ 10 medications (30.2% vs. 23.5%), antipsychotics (30.8% vs. 27.8%), benzodiazepines (30.7% vs. 32.6%), gabapentinoids (21.2% vs. 16.1%), and CNS-active polypharmacy (26.0% vs. 36.9%; p > .05 for all). Patterns of use across settings were consistent when limited to older adults with dementia.
CONCLUSIONS: Older Americans in AL experience a prescription medication burden similar to those in nursing homes. AL settings have an important opportunity to ensure their medication-related clinical services and supports match the needs of their residents.
