Brief Summary:
The purpose of this study is to examine the effect of a low-dose ketamine infusion on depression symptoms within the Emergency Department (ED) visit, and healthcare utilization after leaving the ED, when administered in the ED for depression or suicidal ideation.

Condition or disease Intervention/treatment Phase
Depression Depression Severe Depression Acute Depression and Suicide Suicidal Ideation Drug: Ketamine Drug: Sodium Chloride 0.9% Phase 4

Detailed Description:
Patients will be identified based on either a chief complaint of suicidal ideation, suicide attempt, or severe depression, or if the patient indicates during intake assessment that they have thoughts of harming or killing their self. Identified patients will be assessed by the ED provider for inclusion and exclusion criteria. If the patient is a candidate for the trial and gives their informed consent for enrollment, they will be randomized to receive either ketamine or placebo by a computer program that maintains blinding. The patient will be assessed by psychiatry for disposition and treatment plan prior to receiving the study drug, and will be reassessed four hours after the infusion. Thirty days after the patient leaves the hospital (either leaves from the ED or is discharged from inpatient admission), they will be contacted to follow up on their healthcare utilization after discharge.

Arm Intervention/treatment
Experimental: Ketamine
Ketamine 0.5 mg/kg in 0.9% sodium chloride, total volume 50 mL via intravenous infusion over 40 minutes for one dose.
Drug: Ketamine
Active drug
Other Name: Ketalar

Placebo Comparator: Placebo
0.9% sodium chloride, total volume 50 mL via intravenous infusion over 40 minutes for one dose
Drug: Sodium Chloride 0.9%
Other Name: Normal Saline

Primary Outcome Measures :
  1. Depression Symptom Response [ Time Frame: Baseline, 4 hours ]
    Patients will be classified as a responder or non-responder, with a response defined as a decrease by 50% or greater for the combined depressive symptom scores of the Brief Psychiatric Rating Scale (BPRS), which includes the following domains: emotional withdrawal, guilt feelings, depressed mood, blunted affect, feelings of inferiority, and suicidal ideation. The total depressive symptom score ranges from 6-42, with a higher score indicating a higher level of severity. Response rate will be compared between the treatment and placebo groups.

  2. ED Return Visit [ Time Frame: 30 days from discharge ]
    Number of return visits to the emergency department for any psychiatric reason

Secondary Outcome Measures :
  1. Outpatient follow-up [ Time Frame: 30 days from discharge ]
    Patients will be contacted at 30 days from discharge to obtain outpatient follow-up data. The two results for this outcome are "yes" or "no" to having at least one outpatient visit, either with a psychiatry provider or with a primary care provider to obtain psychiatric care. The number of outpatient visits an individual patient reports, if greater than one, does not affect this outcome. Attempts will be made to confirm each reported visit with the provider to minimize the potential for subject bias.

  2. Intoxication [ Time Frame: Baseline, 2 hours, 4 hours ]
    Change in Visual Analog Scale for Intoxication (VAS-High), which ranges from 0 to 8, with a higher score indicating a greater level of impairment.

  3. Changes in Individual Psychiatric Symptoms [ Time Frame: Baseline, 4 hours ]
    Change in Brief Psychiatric Rating Scale (BPRS) individual symptom scores, with each range from 1-7, with a higher score indicating a higher level of severity. There are 18 total symptoms evaluated on the BPRS.

  4. Length of stay [ Time Frame: Time from arrival in ED to discharge, either directly from the ED or after inpatient admission. Average length of stay is less than 14 days. ]
    Length of stay in hospital
