Ed Patients Presenting with Suicidal Ideations

November 2006

Emergency Medicine Journal Club VignetteI

Mr. P., a 34-year old homeless male presents to your ED with suicidal ideations. He denies any prior suicide attempts or psychiatric diagnoses. Review of your hospital records reveals no prior ED evaluations or hospital admissions. He denies any other medical history. He drinks whiskey daily, but denies illicit substance abuse. Mr. P. has no local family and no primary care physician. His specific suicidal plan is to “jump in front of a car or jump off a bridge.” His physical exam is unremarkable except for an obviously depressed affect. He appears lucid with clear thought processes and no clinically obvious intoxication.

Judging his suicidal threat to be real, you request a psychiatric consultation. After an hour of evaluation time and a negative toxicology screen, your Psychiatrist deems Mr. P. low-risk and safe for outpatient evaluation. Uncomfortably, you discharge him wondering whether any EM-specific risk stratification tools exist for suicidal patients.

You feel fairly certain, based on the history provided by family, that the underlying cause of this patient’s cardiac arrest was an acute myocardial infarction. Despite the lack of ST-elevation the ECG, you wonder if the patient would benefit from early cardiac catheterization to assess for significant acute coronary artery occlusion. You head to the offices on the 8th floor, find a computer, and begin a search to see what the literature says…


PICO Question

Population: ED patients presenting with suicidal ideations

Intervention: Risk stratification with clinical decision rule

Comparison: Non-systematic (gestalt) risk stratification

Outcome: Suicide attempts, successful suicides, other violent behavior (self-harm or injuring others) post-ED evaluation (6-months).

Search Strategy
Touring the ACEP bookstore online, you excitedly note a new textbook: Emergency Psychiatry by Randy Hillard and Brook Zitek (McGraw Hill 2004) which you purchase to help answer this PICO question. Unfortunately, “The Potentially Suicidal Patient” chapter covers only eight pages and does not mention a single CDR related to self-injury risk stratification. You next search the ACEP website for a clinical policy (none) and search fruitlessly for a website for The American Academy of Emergency Psychiatry referenced in Hillard’s textbook (never found). Frustrated and dejected, you turn to Rosen’s Emergency Medicine and quickly learn of Hockberger’s dated SAD PERSON scale which you pull. A Web of Science citation search for Hockberger’s article yields one useful review by Cochrane-Brink which also references the Beck Hopelessness Scale as “the best predictor of eventual suicide”. Coincidentally, while perusing the current issue of Annals of Emergency Medicine you note a brand new self-injury CDR. After discussing these findings with your Psychiatry colleagues, you decide little other literature exists to provide rapid, reliable ED decision making in the form of CDR’s.
