Ketamine for Mood Disorders With Suicidal Ideation
Study Details
Study Description
Brief Summary
This study will explore whether the use of a medication, Ketamine, can help patients who come to the ER with thoughts of suicide by improving their mood and reducing thoughts of suicide. Ketamine has been used for this purpose in patients who have been hospitalized, but it has not been well studied in the ER. The investigators are first trying to show that patients and doctors in the ER find the treatment acceptable. The investigators also hope to determine whether Ketamine is effective in decreasing the severity of patient's suicidal thinking while in the ER. If this treatment works, future studies will look at whether it can help patients be discharged from the hospital earlier.
Research Procedures: Patients will be enrolled into the study on a voluntary basis after the research assistant has fully explained all the risks and benefits of the study (informed consent). Research assistants, Emergency Department staff, and the Psychiatry team will help identify patients for the study. Patients will be asked to complete surveys measuring the degree of their suicidal thinking and mood. Additional information will be collected on patients such as their demographics, current medications, and medical problems. Patients in the study will receive the medication, Ketamine, which will be given through an intravenous catheter (IV) at a dose based on the patient's weight and slowly infused over 40 minutes. Patients will be monitored during their stay in the Emergency Department by Emergency Department physicians and nurses for any signs of side effects to the medication. Patients will be asked to complete several surveys at specific time periods after the administration of Ketamine. All patients in the study will receive usual psychiatric care in addition to the study medication.

Detailed Description
Mood disorders complicated by suicidal ideation (SI) are common among patients presenting to the Emergency Department (ED). Under current standard practice, patients awaiting psychiatric evaluation in the emergency department do not typically receive interventions to address their mood disorder or SI. With no end to the extended ED boarding of psychiatric patients in sight, improvements in the acute treatment of SI with ketamine may help more patients receive prompt and appropriate treatment. Low-dose ketamine has been well studied in psychiatric literature. Studies involving a single dose of ketamine are promising, demonstrating both immediate and sustained reductions in suicidal ideations. Low dose ketamine has been well-studied in the ED for pain, asthma, and agitation, but not mood disorders or SI.
This study aims to determine whether or not it is feasible to administer low dose ketamine in the emergency department for the management of mood disorders with SI. Feasibility of ketamine administration in the ED and will be determined by: (1) ability to recruit participants, (2) tolerability of the intervention, and (3) acceptability by patients/providers. The investigators will also explore whether the administration of ketamine results in improvements in mood and SI.
This prospective open label feasibility pilot study will enroll 20 participants to receive ketamine at 0.5mg/kg infused intravenously over 40 minutes. Patients that have active suicidal ideation as determined by psychiatry staff who are being admitted to psychiatry under voluntary certification will be eligible for the study. The investigators will assess self-reported mood and suicidal ideations pre- and post-infusion of ketamine. Participants will complete assessments at baseline (pre-infusion), 2 hours and 6 hours post-infusion, and daily while in the ED until inpatient disposition.
The investigators hypothesize ketamine administration will be feasible in the emergency department and will result in improved mood and decreased SI.

Outcome Measures
Primary Outcome Measures
- Number and Rate of Participants Recruited into the Study throughout study period [One year]
The study will be considered feasible if the investigators are able to successfully enroll twenty participants into the study over a one year period (~1 - 2 participants per month).
- Completion of total infusion of ketamine by participants [One year]
The study will be considered feasible if the intervention is tolerable to participants with no more than 25% of enrolled participants stopping the infusion of ketamine because of side effects (i.e., early stopping).
- Percentage of participants and providers with positive response to ketamine administration [One year]
The study will be considered feasible if the intervention is considered acceptable to patients and providers (75% positive response on acceptability questionnaires).
Secondary Outcome Measures
- Reduction of SI in mood disorders by ketamine [30 days]
The investigators will assess effectiveness based on changes in self-reported mood and suicidal ideations pre- and post-infusion of ketamine. Participants will complete assessments at baseline (pre-infusion), 2 hours and 6 hours post-infusion, and daily while in the ED until inpatient disposition. The investigators will use the assessments inherent rating scales to determine the reduction in SI, depression, or change in mood and determine if there was a significant decrease in SI in mood disorders after ketamine administration.
Other Outcome Measures
- Effect on in-patient length of stay [30 days]
In exploratory analyses, the investigators will also examine a number of other outcomes including: the average length of stay of inpatient admission
- Effect on indication of other medication administration [30 days]
In exploratory analyses, the investigators will also examine concomitant medications received (e.g., for depression, agitation) by analyzing the percentage of patients who receive other medications in the emergency department.
- Number of participants with return visit to the Emergency Department [30 days]
In exploratory analyses, the investigators will also examine 30-day return ED visits via patient self-report and review of medical records.
