76 The predictive validity of MyHEARTSMAP for psychosocial screening in the emergency department

Background Mental health concerns in childhood and adolescence are prevalent, affecting nearly one million Canadian youth. In the absence of screening, up to 98% of these concerns can go undiagnosed, leading to significant health, educational, and social consequences. Consequently, the American Academy of Pediatrics recommends the development of screening tools to facilitate early identification and access to treatment. The Emergency Department (ED) represents a unique environment to implement such universal screening, as it is immediately accessible and may be the only point of contact for some vulnerable youth with undiagnosed illness. However, there are few existing instruments which take into account commonly cited barriers such as time constraints, disruption of ED flow, limited resources, and patient privacy.
