When assessing a patient with a behavioral crisis, your first priority is safety, for yourself, your team, and the person in crisis. Everything else, the interview, the physical exam, the mental status check, follows only after the scene is secure and you’ve established that no one is in immediate danger. A behavioral crisis can involve suicidal intent, psychosis, extreme agitation, substance intoxication, or all of these at once, and your assessment needs to account for each possibility while keeping the encounter as calm and non-threatening as possible.
Scene Safety and Initial Approach
Before making contact, assess the environment for potential weapons, exits, and bystanders. Position yourself between the patient and the door so you have a way out if the situation escalates. SAMHSA’s 2025 national crisis care guidelines emphasize a “no force first” culture, meaning the goal is to resolve the crisis without physical intervention whenever possible. Law enforcement should not be the default response; behavioral health professionals should lead unless a clear public safety threat exists.
Watch for indicators of imminent violence: clenched fists, pacing, direct threats, a fixation on weapons, or a history of physical assault. Substance use, low frustration tolerance, delusional thinking, and hallucinations all raise the risk. Someone who is withdrawn and making statements about wanting to die requires a different kind of vigilance, but the same level of attention. Conducting a suicide and violence screening early in the encounter is essential for both immediate safety and any safety plan you develop afterward.
De-escalation Before Everything Else
Your tone, posture, and word choice set the trajectory of the entire assessment. Adopt a relaxed, open stance with your hands visible. Maintain good eye contact without staring. Use simple, short sentences and repeat key phrases rather than rephrasing, which can confuse an agitated person or someone experiencing psychosis.
Validate the emotion, not necessarily the behavior. Saying “I can see you’re really frustrated right now” acknowledges the person’s experience without endorsing anything dangerous. Avoid commands, arguments, or clinical jargon. The goal is to bring the emotional temperature down enough that a meaningful assessment becomes possible. Rushing into clinical questions before the person feels safe typically makes things worse.
Rule Out Medical Causes First
One of the most critical steps is distinguishing a psychiatric crisis from a medical emergency that looks like one. Medications, substance use or withdrawal, infections, stroke, metabolic problems like low blood sugar or dehydration, and head trauma can all produce symptoms that mimic psychosis, mania, or severe agitation. A sudden change in behavior after a head injury or after starting a new medication points toward a medical cause. Sudden onset of speech difficulty may indicate a stroke, not a psychiatric episode.
Get a full set of vital signs: blood pressure, heart rate, respiratory rate, and temperature. Research shows that only about half of patients with known psychiatric conditions who are evaluated in emergency settings actually receive a complete set of vitals, which means medical problems get missed. Any abnormal findings, whether fever suggesting infection, rapid heart rate, or low oxygen levels, need to be addressed before attributing the presentation to a behavioral health condition.
A focused physical exam matters here too. Check the pupils: dilated pupils with flushed, hot, dry skin suggest anticholinergic drug effects, while constricted pupils point to opioid use. Horizontal eye twitching can indicate certain drug toxicity, and rotary or vertical eye twitching is associated with PCP intoxication. Inspect the skin for signs of self-harm, bruising, or other trauma. The exam should be thorough enough to catch infection, injury, or toxic reactions that could be driving the behavior.
Gather a Focused History
Once the person is calm enough to engage, start with open-ended questions. “What brings you here today?” or “Tell me about what’s been going on” lets them frame the situation in their own words. Listen for the chief complaint, but also listen for what they’re not saying.
Key areas to cover include:
- Psychiatric history: previous diagnoses, hospitalizations, past crises, and what helped before
- Medical history: chronic conditions, recent illnesses, surgeries
- Medications: current prescriptions, recent changes, and whether they’ve been taking them as prescribed
- Substance use: alcohol, drugs, or new substances, including timing of last use
- Recent stressors: job loss, relationship breakdown, bereavement, housing instability, exposure to violence
- Family history: psychiatric illness, suicide, or violence in the family (patients often won’t volunteer this, so ask directly)
If the patient reports depression, pin down the timeline. “How long have you felt this way?” and “How many days in the past week have you felt like this?” give you much more useful information than a vague acknowledgment. People in crisis can report their own symptoms more accurately than many providers assume. One review found that a careful patient history and physical exam is sufficient to guide further testing, even in patients with serious psychiatric conditions.
Perform a Mental Status Examination
The mental status exam is your structured snapshot of how the person’s mind is functioning right now. It covers several categories, and you’ll gather much of it simply by observing and listening during the conversation rather than running through a checklist.
Start with appearance and behavior: are they dressed appropriately, maintaining hygiene, making eye contact? Note their motor activity, whether they’re agitated, slowed down, or displaying unusual movements. Assess their speech for rate, volume, and coherence.
Ask about mood in the patient’s own words and document it verbatim. “I feel like everything is falling apart” tells you something different than “I’m fine,” even if both patients look distressed. Affect is what you observe: does their emotional expression match what they’re saying?
Thought process describes how the person is thinking, whether their ideas connect logically or jump erratically between topics. Thought content is what they’re thinking about. This is where you directly assess for suicidal ideation, homicidal ideation, and delusions. Don’t dance around it. Asking “Are you thinking about hurting yourself?” does not plant the idea; it opens a door that may save their life.
Check orientation: do they know their name, where they are, and today’s date? Someone who is normally oriented but suddenly cannot answer these questions may be experiencing delirium rather than a primary psychiatric illness. This distinction matters enormously because delirium often signals a medical condition that needs immediate treatment, such as an infection, organ failure, or drug toxicity.
Assess Suicide and Violence Risk
Every behavioral crisis assessment should include a structured risk evaluation, regardless of the presenting complaint. Ask about suicidal thoughts, intent, and whether the person has a plan. Ask about access to means, particularly firearms. Ask about homicidal thoughts. These questions should be direct and non-judgmental.
If the person is at high risk, developing a safety plan is the next step. SAMHSA guidelines stress that safety plans should be collaborative, brief, and centered on the person’s own strengths and goals. A good safety plan identifies warning signs, coping strategies, people the person can contact for support, and ways to make the environment safer (like removing access to weapons or stockpiled medications). This isn’t a form you hand someone. It’s a conversation that results in a shared document both of you believe in.
Understand Consent and Legal Boundaries
A competent patient can refuse care. But when someone lacks the capacity to make decisions, as is often the case during psychotic episodes, active suicidal behavior, or severe intoxication, providers are generally obligated to treat. Failing to act in these situations can constitute negligence. The legal justification rests on implied consent: the assumption that a reasonable person would want life-saving treatment if they were able to make that choice.
Physical restraint is a last resort, used only when someone poses a direct danger to themselves or others that cannot be managed any other way. If restraints are applied without following proper legal procedures, including documentation and, when possible, informed consent from the patient or a family member, providers risk liability. In one notable case, a hospital was found liable for false imprisonment after using physical and chemical restraints without initiating involuntary commitment proceedings. The takeaway: every use of force carries legal weight and must be justified, documented, and time-limited.
The legal landscape varies by state, but the core principle is consistent. In true emergencies involving serious threat of violence, attempted suicide, or risk of irreversible deterioration of a serious mental illness, the duty to protect the individual and the public overrides the right to refuse treatment. Outside of those narrow circumstances, the patient’s autonomy stands.
