Emergency Psychiatry Flashcards
What two interventions have been shown to decrease suicide mortality? How can we find out if they are going to?

What are some medical factors associated with increased risk of suicide?
- Agitated delirium
- Chronic or terminal illness
- Disfigurement - as in treatment for head and neck cancer

Farmers - have access to pesticides
What are you trying to assess when asking the patient questions regarding their suicide intent? What is most concerning?
Imminence
-> Do they have an intent to die, with lethal means now
Most concerning: Direct threats to harm / kill oneself, actively looking for ways to do so, talking / writing about death, dying, and suicide

The patient’s family members, if available.
-> Do they ask about killing themselves, have ways to do this, been using substances / acted depressed / tearful? Attempted suicide before?
How do you treat suicidal patients generally?
Remove their means, being sure not to prescribe risky drugs (opioids, sedatives, TCAS)
Determine inpatient vs outpatient by telling if active vs passive thoughts
Treat their underlying psych and medical conditions aggressively
What biological treatments can be used for treatment of suicidality?
- Lithium
- Clozapine - Schizophrenia / Schizoaffective disorder
- ECT or ketamine - decreased suicidality acutely
- Antidepressants can be used, but beware of initial suicidality increases in younger people (black box warning)
What therapies can be used for suicidality?
Repeated visits to PCP
Cognitive behavioral therapy
Especially: dialectical behavioral therapy -> reduce self-injurious behavior (used commonly in borderline PD)
What scale is best used in the detection of suicidality?
Columbia Suicide Scales
What is an Acute Suicidal Affective Disturbance?
A sudden increase in suicidal intent occurring over minutes to days
-> patient feels a disgust in others and themselves which they feel can never be changed
What is the #1 risk factor for violence?
History of violence
What are the three stages of violence?
