Allen Richert4 enrolled

Overview

This study will evaluate the effect of ketamine on the treatment of patients hospitalized with suicidal thoughts. Half of the patients will receive one dose of ketamine in the vein. The other half will receive a placebo. Because we think that ketamine will improve depression and suicidal thoughts, we expect that patients who receive ketamine will require less time in the hospital than patients who receive placebo.

Patients admitted to UMMC's psychiatry inpatient unit with suicidal thoughts will be given the opportunity to participate in the study. Those patients who consent to participate, after being informed about the study and its risks, will be randomized to receive an IV infusion of either saline or ketamine 0.5 mg/kg. The infusion will be given within 24 hours of arriving on the psychiatry inpatient unit. We will record the dates and times that the patient was admitted to and discharged from the psychiatric inpatient unit. At completion of the study, we will compare the average length of stay, defined as date and time of discharge minus date of time of admission, of the group that received ketamine to the average length of stay of the group that received placebo.

Inpatient Hospital Length of Stay

We defined length of hospital stay as the difference between 1) the date and time that the patient was admitted to the psychiatry inpatient unit and 2) the date and time that the patient was discharged from the psychiatry inpatient.

Time frame: The dates and times of each patients' admission to and discharge from the inpatient unit (i.e., the data necessary to calculate length of stay) were collected by chart review performed approximately 6 months after enrollment in the study.
