简要总结
This is a prospective randomized single-blind simulator-based trial. 156 4th year medical students were randomised to receive one of three different suspected diagnoses of a pre-treating physician (no diagnosis, myocardial infarction, pulmonary embolism) prior to the task to make a focussed assessment and perform first management steps in a patient presenting to the emergency department. The patient (simulator) suffered from an acute myocardial infarction. Video recordings were obtained during simulation and used for data analysis. Primary endpoint was the participants' final presuptive diagnosis.
