When depression is diagnosed, older adults are as likely as younger adults to be prescribed pharmacotherapy and psychotherapy.

Objective: This study examined age group differences in the rates of depression diagnosis and treatment using a national probability sample.

Methods: Using data from the 2012 National Ambulatory Medical Care Survey (n=62,723 visits by patients aged 18+ years), we used bivariate and multivariable binary logistic regression analyses to test age group differences in antidepressant medication (ADM) and psychotherapy prescribed/ordered or provided at visits during which depression was diagnosed.

Results: Visits by older adults were less likely to result in a depression diagnosis than visits by younger individuals: 2.46% and 1.80% in the 65-74 and 75+ age groups, compared to 4.06%, 4.24% and 4.12% in the 18-29, 30-49 and 50-64 age groups, respectively. Of all visits involving diagnosed depression, 65.88% included prescribing/ordering or providing ADM and 19.01% included psychotherapy ordering or providing, without significant age group difference. Prescribing/ordering or providing ADM occurs frequently during visits to physicians regardless of specialty, while psychotherapy was ordered or provided mostly during visits to psychiatrists.

Conclusions: During ambulatory care visits in which depression was diagnosed, older adults were as likely as younger adults to be prescribed/provided treatment; however, in more than 30% of visits by depressed older adults neither ADM nor psychotherapy was prescribed.
