Ketamine + Cognitive Training for Suicidality in the Medical Setting
October 4, 2023 updated by: Rebecca Price
This project seeks to identify the acute and longer-term impact of a single dose of intravenous ketamine among suicidal patients referred for psychiatric consultation/liaison in the medical inpatient setting.
The investigators will then test whether ketamine's rapid effects can be extended by introducing helpful information delivered by a computer-based training protocol.
This work could ultimately lead to the ability to treat suicidality more efficiently and with broader dissemination by rapidly priming the brain for helpful forms of learning.

Detailed Description
NOTE: Edits were made to the outcome measures sections to improve clarity regarding the a priori analytic plan with respect to the "Time Frame" of measurements and to reduce redundancies.
Timepoints that will be analyzed as trajectories over windows of time and measurements that will be analyzed as composites are now more clearly specified.
The previous entries correctly identified all relevant measures and timepoints, but implied incorrectly that each timepoint/measure would be analyzed in isolation.

- Mini-Mental State Exam (MMSE) < 21
- Current pregnancy or breastfeeding
- Reading level <5th grade as per WRAT-3 reading subtest AND patient declines to have all questionnaire items and task instructions read aloud to them at all assessment points
- Past intolerance or hypersensitivity to ketamine or esketamine
- Patients taking St John's Wort
- Patients who have received ECT in the past 1 month prior to intake
- Patients at ongoing risk for severe substance or alcohol withdrawal related issues (e.g., delirium tremens, severe opiate withdrawal) or who present with substance-induced psychosis
- Arrested or incarcerated individuals brought in by the legal system for medical stabilization
