Effect of Mental Health Screening and Integrated Mental Health on Adolescent Depression–Coded Visits

Adolescent depression causes morbidity and is underdiagnosed. It is unclear how mental health screening and integrated mental health practitioners change adolescent depression identification. We conducted a retrospective primary care network natural cohort study where 10 out of 19 practices implemented mental health screening, followed by the remaining 9 practices implementing mental health screening with less coaching and support. Afterward, a different subset of 8 practices implemented integrated mental health practitioners. Percentages of depression-coded adolescent visits were compared between practices (1) with and without mental health screening and (2) with and without integrated mental health practitioners, using difference-in-differences analyses. The incidence of depression-coded visits increased more in practices that performed mental health screening (ratio of odds ratios = 1.22; 95% confidence interval =1.00-1.49) and more in practices with integrated mental health practitioners (ratio of odds ratios = 1.58; 95% confidence interval = 1.30-1.93). Adolescent mental health screening and integrated mental health practitioners increase depression-coded visits in primary care.
