Psilocybin After Trauma Surgery for Pain

Официальное название

Single Dose Psilocybin for a Post-surgical Trauma Inpatient Population for Pain, Mood, and Opioid Use Disorder

Обзор

The goal of this clinical trial is to evaluate whether a single dose of psilocybin is feasible and safe for adults with opioid use disorder (OUD) who are recovering from trauma surgery. The main questions it aims to answer are: 1. Is a single psilocybin dose feasible to administer during postoperative hospitalization? 2. Is psilocybin safe in this patient population? 3. How does psilocybin affect postoperative pain, opioid use, anxiety, and depression after hospital discharge? Participants will: Receive one oral dose of psilocybin during their postoperative inpatient stay Complete assessments of pain, mood, and opioid use during recovery

Подробное описание

This is an open-label pilot feasibility trial conducted at a single academic medical center. Fourteen participants receive a single oral dose of psilocybin during inpatient hospitalization following trauma surgery. Outcomes in the psilocybin group are compared with a retrospectively identified standard-of-care cohort of 56 trauma surgery patients with opioid use disorder, identified through electronic medical record review.

The standard-of-care cohort is selected using propensity score methods based on baseline characteristics, including age, sex, trauma diagnosis, psychiatric comorbidities, baseline medications, comorbid conditions, type of surgery, and baseline opioid consumption measured in morphine milligram equivalents.

No interim efficacy analyses are planned. After the first three participants have received psilocybin and completed the one-week follow-up assessments, the Data and Safety Monitoring Board reviews safety data to assess ongoing risk and determine whether study procedures should continue unchanged.
