The Influence of Project ECHO and Integrated Behavioral Health in Primary Care on Emergency Department Visits Among Youth Diagnosed with Depression.

Rates of depression among youth and emergency department (ED) visits for un- or under-treated symptoms are on the rise. Early identification and treatment of depression is imperative at the patient, program, system, and population levels. This paper examines the individual and cumulative impact of Project ECHO and the inclusion of IBH services in pediatric primary care practices on mental health-related ED rates among youth diagnosed with depression for those practices. Twenty-eight practices participated and provided data on 5,388 patients diagnosed with depression who were seen between 2019 and 2022. A binominal mixed effect model was used to examine the impact of Project ECHO and IBH on mental health-related ED rates among youth diagnosed with depression per month within each practice. Compared to practices without an IBH program, those who implemented IBH had a significantly lower rate of mental health-related ED visits among this patient population (Incident Rate Ratio (IRR) = 0.80, p = .005, 95% Confidence Intervale (CI) = 0.68, 0.93). No significant differences were found between practices regardless of participation in Project ECHO, nor was there a significant interaction effect between practices that employed Project ECHO and IBH in combination. This study shows promising results with IBH having a positive impact on practice outcomes compared to treatment as usual, while Project ECHO in isolation or combined with IBH did not significantly affect rates of mental health-related ED visits.
