The investigators we co-designed, with parents and youth, an acute mental health care bundle-a set of evidence informed practices collectively used to improve the quality of care. The bundle of care includes:~Triage-based evaluation of risk for suicide [Ask Suicide-Screening Questions (ASQ) and HEADS-ED, an assessment mnemonic (Home; Education & Employment; Activities & Peers; Drugs & Alcohol; Suicidality; Emotions & Behaviours; Discharge or Current Resources]~Focused mental health team psychosocial evaluation to guide decision-making~Choice And Partnership Approach (CAPA) to care~This bundle of care also strives to remove the ED physician as the gatekeeper to mental health care and will facilitate, ideally, 24-48 hour urgent mental health follow-up (booked before the child/family leave the ED), with up to 96 hours to coordinate follow-up for patients attending the ED on weekends.~Primary Research Objective: To determine, in an 8-site, hybrid Type I cluster randomized effectiveness-implementation trial, if an acute mental health care bundle, compared to standard care, improves wellbeing at 30 days in children and youth seeking ED care for mental health and substance use concerns.~Secondary Research Objectives: (1) To determine if the bundle improves wellbeing, satisfaction with care, family functioning, and health care delivery; (2) To identify modifiable barriers, constraints, and enablers of bundle implementation fidelity and effectiveness; (3) To test if trial intervention effects are moderated by sociodemographic characteristics (sex, gender, ethnicity, culture, education, and socioeconomic status); and (4) To assess the cost-effectiveness of the approach.
The investigators will determine, in an 8-site, hybrid Type 1 cluster randomized effectiveness implementation trial, if an acute mental health care bundle, compared to standard care, improves wellbeing at 30 days in children and youth seeking emergency department care for mental health and substance use concerns.
