Workup
ACEP Clinical Policies: Psychiatric Patient[2]
- Do not routinely order laboratory testing on patients with acute psychiatric symptoms. Use medical history, previous psychiatric diagnoses, and physician examination to guide testing. (Level C Recommendation)
- Tailor medical workup based on individual clinical scenario
- Pregnancy test in reproductive age female
- TSH often reasonable if new mania
- Consider toxicologic workup if unclear med/substance history
- Consider Head CT if altered and no psychiatric history
- Consider LP if high concern for infectious CNS cause
- Consider lab evaluation for causes of delirium
Diagnosis
- Clinical - see clinical features
- Exclude organic causes as best as possible
ED Management
- Psychiatric evaluation - typically with admission
- Medications for agitation as needed - consider atypical antipsychotics
General Management
- Psychotherapy
- Supportive, family, group
- Pharmacotherapy[3]
- Lithium
- Long term use reduces suicide risk
- Lithium toxicity can be fatal
- Mood stabilizers
- Atypical antipsychotics
- Often as adjunct to mood stabilizer, less common monotherapy
- Lithium
- ECT
Disposition
