Mental Health Crisis Response: What EMS Providers Need to Know

By Jointra Editorial Team, Certified EMT

The Scale of the Problem

Mental health and behavioral health calls now account for an estimated 20–25% of all EMS responses in urban systems. EMS providers are often the first — and sometimes the only — clinical contact for people in psychiatric crisis. Yet most EMS training devotes only a fraction of its hours to these calls. The result is inadequate preparation for some of the most complex patient encounters in pre-hospital medicine.

Medical Emergencies That Mimic Psychiatric Illness

Before assuming a presentation is psychiatric, rule out medical causes. This is one of the most critical skills in EMS.

Causes of altered behavior or psychiatric-appearing presentation:

• Hypoglycemia — check glucose on every AMS patient
• Hypoxia — pulse oximetry, respiratory assessment
• Intoxication or overdose — toxicological history
• Head trauma — examine for signs of TBI
• Stroke — FAST assessment
• Thyroid crisis — rare but presents dramatically
• Encephalitis — fever, altered mental status
• Postictal state — history of seizures
• Medication toxicity — lithium, anticholinergics, serotonin syndrome

Every agitated, confused, or behaviorally disturbed patient gets a full medical assessment before being presumed psychiatric.

De-escalation in the Field

Use a calm, non-threatening tone. Speak slowly and clearly. Use the person's name if you know it.

Give space. Don't crowd the patient. Maintain a distance of at least 6 feet initially unless safety requires closer contact.

Listen actively. Let the person speak. Validate their feelings without agreeing with delusions.

Avoid confrontation. Don't argue about the reality of hallucinations or delusions.

Give simple choices. "Would you like to sit down?" keeps the person involved in small decisions.

Be honest. Don't promise things you can't deliver.

Suicide Risk Assessment

EMS providers are not mental health clinicians, but they need to gather key information:

• Does the person have a plan? (What, how, when)
• Do they have access to means? (Firearms are the most lethal)
• Have they made a previous attempt?
• Is there a psychiatric history or recent medication change?
• Are they under the influence of substances?

All suicidal ideation with plan and means should be transported.

Use of Force and Restraint

Restraint is a last resort — used only when the patient poses an imminent threat to themselves or others. Positional asphyxia is a real risk; never restrain a patient face-down. Never leave a restrained patient unmonitored. Document thoroughly.

In many jurisdictions, law enforcement co-responds. Know your local protocol for psychiatric holds and involuntary transport.

The Goal: Right Care, Right Place

EMS has an opportunity to divert appropriate mental health calls away from emergency departments and toward crisis centers, mobile crisis teams, or peer support services. Know your local mental health resources. Not every psychiatric call belongs in an ED.
