Universal depression screening to improve depression outcomes in primary care: Sounds good, but where is the evidence?

The 2016 recommendation statement by the U.S. Preventive Services Task Force (USPSTF) endorsed screening for depression in the general adult population. The recommendation was mainly based on studies that compared enhanced depression care that included depression screening with usual care. In contrast to the USPSTF recommendation, the 2013 guidelines from the Canadian Task Force on Preventive Health Care (CTFPHC) recommended against routine depression screening. The CTFPHC could not identify any studies comparing depression outcomes of usual care with and without the addition of routine depression screening. In the absence of evidence of clinical benefit, there are concerns that wide adoption of the USPSTF recommendation for universal depression screening would lead to overdiagnosis of depression and an increase in inappropriate prescription of antidepressant medications.
