Incidence of Homelessness among Veterans Newly Diagnosed with Alzheimer's Disease and Related Dementias.

BACKGROUND

To determine the incidence of homelessness among Veterans diagnosed with Alzheimer's disease and related dementias (ADRD).

METHODS

We used Veterans Affairs (VA) administrative records to identify Veterans with a new ADRD diagnosis anytime between 2010-2019. Among these Veterans, we calculated the incidence of homelessness, and estimated the association between demographics, comorbidities and hazard of homelessness.

RESULTS

The incidence rate of homelessness was highest for Veterans diagnosed with ADRD between 18-49 years of age (14.9 per 1,000 person-years; 95%CI: 13.6, 16.3) and lowest for Veterans diagnosed with ADRD at 90+ years (0.3 per 1,000 person-years; 95%CI: 0.2, 0.4). The adjusted hazard ratio of homelessness was higher for unmarried Veterans, and those with alcohol use disorder, substance use disorder, liver disease, depression, hypertension, lung disease, post-traumatic stress disorder and psychoses.

CONCLUSIONS

Younger age and being unmarried at the time of ADRD diagnosis are associated with a greater risk of experiencing homelessness.
