How to manage aggression in a patient with potential psychiatric disorders, neurological conditions, or substance-induced states?

Managing an Aggressive Patient

Immediately position yourself at an angle to the patient (not directly facing them), maintain approximately two arms' length distance, ensure an unobstructed exit path, and designate one staff member to engage the patient using calm, concise verbal de-escalation techniques. 1, 2

Immediate Safety Positioning

• Stand at an angle to the patient rather than directly facing them, as direct confrontation is perceived as threatening 1, 2
• Maintain approximately two arms' length distance to ensure safety while remaining engaged 2
• Keep your hands visible and unclenched to avoid implying you have a hidden weapon 2
• Ensure an unobstructed exit path for both yourself and the patient 2
• Have security personnel nearby and within sight but not immediately surrounding the patient, as excessive visible security increases agitation 2
• Place the patient in a quiet room without excessive stimulation when possible 2

Verbal De-escalation Protocol

Establish Single Point of Contact

• Designate only one staff member to interact with the patient, as multiple voices and messengers confuse and further agitate the patient 1, 2
• Introduce yourself and orient the patient to the setting and what to expect 1, 2

Communication Technique

• Use simple language with concise sentences, as agitated patients have impaired ability to process complex information 1, 2
• Speak in a calm demeanor with neutral facial expressions 2
• Allow adequate time for the patient to process information and respond 1, 2
• Use active listening techniques: "Tell me if I have this right..." or "What I heard is that..." to convey the patient is heard and understood 1, 2
• Identify the patient's goals and expectations: "What helps you at times like this?" 1

Set Clear Boundaries

• Establish reasonable limits with clear, non-punitive consequences: "We're here to help, but it's also important that we're safe with each other and respect each other" 1, 2
• State safety expectations clearly: "Safety comes first. If you're having a hard time staying safe or controlling your behavior, we will need to take steps to ensure everyone's safety" 1, 2
• Offer realistic choices to help the patient regain a sense of control 1, 2
• Minimize bargaining but coach the patient on how to maintain control 1

Critical Actions to AVOID

• Never approach with stern threats of restraint and sedation as your opening strategy, as this is provocative and escalates rather than de-escalates agitation 2
• Do not assume restraints will be necessary before attempting verbal de-escalation 2
• Avoid making the patient feel threatened through aggressive posture or behavior 1, 2
• Do not allow multiple staff members to simultaneously engage the patient verbally 1, 2

Assessment During De-escalation

While maintaining safe distance, assess for:

• Triggers of current agitation, including medication non-adherence, substance use, and psychotic symptoms 2
• Active psychotic symptoms that may be driving aggressive behavior 2
• Substance intoxication or withdrawal, as this affects medication choices if pharmacologic intervention becomes necessary 2
• Suicide and homicide risk as part of the mental status examination 2

When Verbal De-escalation Fails

Medication Selection Algorithm

If verbal de-escalation is unsuccessful after genuine attempts, pharmacologic intervention is indicated 2:

For suspected psychiatric causes of agitation:

• Antipsychotics are preferred 1
• Haloperidol 2-5 mg IM for prompt control 3
• Offer voluntary oral medication first before considering involuntary IM administration 4

For suspected medical/intoxication causes:

• Benzodiazepines are preferred 1
• Lorazepam 2 mg IM is effective monotherapy 4

For severe agitation of unknown etiology:

• Consider combination therapy: haloperidol plus lorazepam IM may produce more rapid sedation than monotherapy 1, 4

Physical Restraint Considerations

• Physical restraints should only be used when the patient poses imminent danger to self or others and less restrictive interventions have failed 1, 2
• Ensure trained staff are present to safely implement restraint procedures 1, 4
• Face-to-face evaluation by a licensed independent practitioner within 1 hour of chemical or physical restraint is required 4
• Continuous monitoring by trained nursing personnel is mandatory after restraint 4
• Assess every 15 minutes for patient status, vital signs, and response 4

Post-Intervention Debriefing

• Conduct debriefing with the patient once they have regained self-control to identify triggers and develop prevention strategies 1, 4
• Explain why the intervention was necessary if restraint was used 1
• Ask the patient to explain their perspective 1
• Review options and alternative strategies if the situation arises again 1

Common Pitfalls

• Never use chemical restraint as punishment or for staff convenience, only to prevent dangerous behavior to self or others 4
• Do not use PRN (as needed) orders for chemical restraint, as each administration requires a specific order 4
• Avoid benzodiazepines in patients with suspected substance use disorders unless withdrawal is the primary concern 4
• Watch for paradoxical rage reactions with anxiolytics, particularly in vulnerable populations 4
