ED TREATMENT/PROCEDURES
  • Verbal de-escalation:
    • Attempt to clarify and validate patient’s immediate concerns
    • Calmly explain potential need for a restraint if de-escalation is not successful
    • Offer patient choices when possible
  • Seclusion:
    • If an appropriate room is available, this may obviate the need for restraint
  • Physical restraint:
    • Follow your institutional protocol
    • Must document appropriate reason for restraint, attempts to verbally de-escalate, and plans for appropriate monitoring and reassessments
    • Whenever possible, treating physician should not be part of restraint team
    • Use leather restraints for combative patients; soft restraints for patients who are unlikely to be combative or try to elope
    • Supine position if patient needs to be examined; side position if aspiration risk is significant
    • If restraint in prone position is needed, ensure adequate airway is maintained
  • Chemical restraint:
    • Offer voluntary PO or IM sedative medication prior to initiating involuntary restraint
    • Avoid PO medications for involuntary restraint due to bite risk
    • Choice of medication should depend on underlying cause; either a benzodiazepine or a neuroleptic or both may be appropriate:
      • If agitation results from delirium or other medical condition, 1st attempt to treat the underlying cause
      • Consider benzodiazepines for hyperadrenergic (including cocaine) state or if there is a contraindication to neuroleptics
      • Consider neuroleptics for most primary medical or psychiatric causes, sedative intoxication, or primary behavioral cause
      • Often used in combination
    • Contraindications to neuroleptics:
      • Knowledge of or suspicion for Parkinson disease, dementia with Lewy bodies or frontotemporal dementia
      • Neuroleptic malignant syndrome, dystonic reaction, or catatonia
      • Prolonged QT
      • Anticholinergic overdose
    • Potential adverse effects:
      • Dystonia: Treat with IM benztropine 1 mg or IM diphenhydramine 50 mg
      • QTc prolongation and/or torsades de pointes (rare)
      • Neuroleptic malignant syndrome (rare): Stop all antipsychotics; begin intensive monitoring and supportive care
MEDICATION
ALERT
  • Patients who are elderly, have medical or neurologic illness, or have cognitive impairment are more vulnerable to adverse effects and may respond to lower doses (e.g., haloperidol 0.5 mg)
  • If 1st dose of IM haloperidol is ineffective, may be repeated after 30–60 min.
  • First line:
    • Haloperidol: 5–10 mg IV, IM, or PO
    • Lorazepam: 1–2 mg IV, IM, or PO
  • Second line:
    • Droperidol: 2.5–5 mg IV or IM; watch QTc
    • Olanzapine: 5–10 mg IM or PO; if IM, do not give with IM/IV benzodiazepines due to risk of respiratory depression
    • Risperidone: 0.5–1 mg PO
    • Ziprasidone: 10 mg IM every 2 hr, not to exceed 40 mg IM per day
FOLLOW-UP
DISPOSITION
Admission Criteria
  • Medical admission for medical conditions not temporary or reversible in the ED
  • Medical admission if further medical workup needed for which ED setting is not optimal
  • Psychiatric admission if patient has a treatable psychiatric illness appropriate for inpatient level of care
  • Involuntary admission for safety may be necessary according to criteria defined by individual state laws
Discharge Criteria
  • Underlying medical or psychiatric causes have been stabilized
  • Appropriate follow-up is in place
  • Access to weapons has been assessed
  • If intoxication played a role in presentation, sober re-evaluation should occur prior to discharge
  • Discharge to police custody may be appropriate if no psychiatric or medical issues remain
  • If patient elopes, must consider imminent danger to self or others; notify police if risk is high or if safety evaluation not complete
  • Duty to warn or protect 3rd parties from risk of harm: “Tarasoff” laws vary among states, so know yours
ADDITIONAL TREATMENT
Issues for Referral
  • Psychiatric consultation in the ED can be helpful, especially if primary mental illness suspected
  • Other consultation may be indicated based on the underlying etiology
FOLLOW-UP RECOMMENDATIONS
  • Patients with psychiatric illness should follow-up with community mental health provider
  • Patients who are using substances should be offered counseling and/or detox
PEARLS AND PITFALLS
  • Do not assume that patients with violent behavior have only psychiatric problems
  • Patients who have been restrained require appropriate monitoring, including regular nursing checks and VS, and labs/ECG if chemical restraints are used
  • “Distracting staff” is annoying and may interfere with the care of other patients, but this is not an indication for restraints
  • Document need for restraints and renewal of restraints per your hospital’s protocol
