Alzheimer Disease or Other Dementias in Adult Day Services Centers, 2020.

Objectives-Alzheimer disease or other dementias are among the most common chronic conditions of adult day services center (ADSC) participants. This report compares prevalence of these conditions (referred to collectively as dementia) among participants in ADSCs that provide specialized care for dementia with other ADSCs, by census region, metropolitan statistical area status, chain affiliation, and ownership type. Methods-This report uses data from the ADSC component of the 2020 National Post-acute and Long-term Care Study. The survey collects data on ADSCs every 2 years from all 50 states and the District of Columbia. Data were collected from January 2020 through mid-July 2021. The results are based on survey responses from about 1,800 eligible ADSCs from a census of 5,500 ADSCs and are weighted to be nationally representative. The percentage of participants diagnosed with dementia is calculated from responses to a question about the number of current participants diagnosed with dementia. Geographical and ADSC characteristics include census region, metropolitan statistical area, ownership status, and chain affiliation. Results-In ADSCs that provide specialized dementia care, 42.2% of participants had dementia, while 22.7% of participants also had dementia in ADSCs that do not specialize in dementia care. The overall prevalence of dementia was similar across regions, with a slightly lower percentage in the West. Dementia was more prevalent in ADSCs in metropolitan statistical areas, nonchain centers, and nonprofit centers. In general, for each of the selected characteristics, the prevalence of dementia was higher in specialized centers than in nonspecialized centers.
