A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to evaluate the effectiveness of a one-time intramuscular dose of 100mg ketamine combined with a brief psychosocial intervention known as the Crisis Response Plan for adults experiencing acute suicidal ideation in the emergency department. Participants will be randomly assigned to receive either the combination treatment or usual care. The study will assess changes in suicidal thoughts and overall safety through various follow-up assessments conducted at two hours, three days, and one month post-treatment. The trial will include patients who have been cleared for psychiatric hospitalization to ensure close monitoring and safety during the intervention.
