Depression in assisted living: results from a four-state study.
OBJECTIVE
Assisted living is a rapidly-growing sector of long-term care, but little research has been done on depression in this setting. Using data from a large sample of assisted-living residents, the authors sought to 1) describe the prevalence of depression and depressive symptoms; 2) identify resident characteristics associated with depression; and 3) examine the relationship between depression and the rate of nursing home placement and mortality.


METHODS
A group of 2,078 residents age 65 and older were enrolled from 193 assisted-living facilities across four states (Florida, Maryland, New Jersey, and North Carolina). Residents were classified as depressed if their score on the Cornell Scale for Depression in Dementia (CSDD) exceeded 7.


RESULTS
Using this criterion, 13% were depressed, and only 18% of those were on antidepressants. Over one-third of residents had symptoms of depression, such as anxious expression, rumination, or worrying, and 25% displayed sad voice, sad expression, or tearfulness. Depression was significantly associated with medical comorbidity, social withdrawal, psychosis, agitation, and length of residence in the facility. Depressed residents were discharged to nursing homes at 1.5 times the rate of nondepressed residents. Rates of mortality were also higher for depressed residents, but only those with severe depression (CSDD >12) had a statistically significant increased rate of death.


CONCLUSIONS
The mission of assisted living is to help older adults retain autonomy, privacy, and quality of life in a personalized environment. Greater effort should be made to detect and treat depression in this setting, both to reduce suffering and prolong the resident's ability to remain in their preferred environment.
