HEADS-ED

Why use it

Mental health presentations account for approximately 5–9% of all pediatric emergency department visits globally, and this proportion is increasing. Emergency clinicians without specialized psychiatric training often find it challenging to systematically assess the severity and acuity of pediatric mental health crises. The HEADS-ED provides a standardized, validated screening approach administered in under 10 minutes, improves consistency in psychiatric referral decisions, and ensures key risk domains — particularly suicidality — are always assessed.

About

The HEADS-ED is a validated pediatric mental health screening instrument developed by Cappelli and colleagues at the Children's Hospital of Eastern Ontario (CHEO) and published in Pediatric Emergency Care in 2012. It was designed for use in emergency department settings to screen children and adolescents (ages 8–17) for acute mental health needs and to identify those requiring immediate psychiatric consultation. The acronym encodes seven psychosocial domains: Home, Education/Employment, Activities/Peers, Drugs/Alcohol, Suicidality/Self-harm, Emotions/Behaviors, and Discharge Resources. Each domain is scored 0–2 based on the severity of problems identified. Total scores range from 0 to 14. The tool is administered by emergency nurses or clinicians and bridges the gap between non-psychiatric emergency staff and specialized mental health services. A validated score threshold of ≥7 is associated with significantly increased need for urgent psychiatric consultation, with sensitivity of 80% and specificity of 71% in the original study.

When to use

• Any child or adolescent (aged 8–17 years) presenting to the emergency department with a primary or secondary mental health concern
• Patients presenting with suicidal ideation, self-harm, behavioral crisis, or emotional dysregulation
• Triage screening in pediatric emergency departments where mental health wait times are prolonged
• Pre-consultation assessment before child psychiatry consultation to focus the clinical discussion
• Repeated assessments during the ED visit to track clinical changes in acuity
• NOT validated for children under age 8 — use alternative age-appropriate tools for younger children

Formula

Pearls & pitfalls

• The Suicidality/Self-harm (S) domain is the most critical individual item — a score of 2 (active ideation with plan, recent attempt, or active self-harm) requires immediate psychiatric consultation regardless of total HEADS-ED score.
• Discharge Resources (D) is the final domain and specifically assesses whether safe discharge is feasible — a score of 2 (no safe discharge option) must prevent discharge until adequate resources are secured.
• The HEADS-ED was validated for children ages 8–17; extrapolation to younger children or adults may not be appropriate.
• The tool should be administered in private, without the parent/caregiver present if possible, to promote honest disclosure — particularly for the Drugs/Alcohol and Suicidality domains.
• The HEADS-ED is a screening tool, not a psychiatric diagnostic instrument — a positive screen (score ≥7) indicates need for psychiatric assessment, not a specific diagnosis.
• Inter-rater reliability is strong (kappa 0.71–0.83 per domain) when administered by trained ED nurses.
• Even a score of 0 does not guarantee safety — use clinical judgment alongside the HEADS-ED, particularly in young children who may not verbalize suicidal intent.
• Combining HEADS-ED with the Columbia Suicide Severity Rating Scale (C-SSRS) for suicidality specifically can improve overall sensitivity for suicidal risk detection.

Next steps

Score 0–6 (Lower Risk): Mental health issue may be less acute in the emergency setting. Provide resources, safety planning, and outpatient follow-up referral. Social work consultation if available. Reassess if clinical condition changes. Score 7–10 (High Risk): Urgent psychiatric consultation is indicated. Do not discharge without psychiatric assessment. Ensure safe ED environment. Score 11–14 (Critical): Immediate psychiatric consultation required. 1:1 observation. Remove potential means of self-harm. Immediate family/caregiver notification. Any Suicidality domain score of 2 OR Discharge Resources domain score of 2: Requires immediate action regardless of total score.
