A 4.5 day full immersion intensive skills week for emergency medicine and surgical training for finishing second year medical students was performed on a 20 acre movie studio. Utilizing hyper-realistic medical emergency scenarios, we simulated all events beginning at the point of injury, continuing to treatment en route, and ending at transition of care to surgical intervention. The trainees staffed an emergency room (ER) and two operating rooms (OR), triaged multiple victims and performed real surgical procedures on role-playing actors wearing the Human Worn Partial Task Surgical Simulator. Saliva was collected before and after scenarios (i.e., multiple victims from an accident, gun fight, and improvised explosive device) and assayed for cortisol and alpha-amylase (sAA). In addition EKG data looking at R-R interval data was collected. Results from the salivary biometrics and heart rate variability data about the stress response and learning suggests that we are able to identify not only habituation but also whether the student is capable of learning/performing in a given scenario.
Can biometrics measuring the stress response be used to identify habituation?
1)THIS PROJECT IS TO IDENTIFY THE CORRECT PHYSIOLOGIC MARKERS OF STRESS AND HABITUATION THOUGHT TO BE ASSOCIATED WITH IMPROVED COMPLEX EDUCATION.
2)LONG TERM OUR OBJECTIVE IS TO SHOW THAT REALISTIC IMMERSION SIMULATION TRAINING IS BETTER THAN CONVENTIONAL EDUCATION METHODS.
