研究概览
简要总结
Medical reasoning is a form of inquiry that examines the thought processes involved in making medical decisions. When physicians are faced with patients' symptoms or signs, their thought processes follow either direct shortcuts to suspect a diagnosis or go into a deeper and more analytic process to reach a diagnosis. The second pathway is less prone to biases and errors. This study explores whether the use of an interactive visual display of probabilities of pulmonary embolism generated from positive or negative test results will increase the adherence to evidence based guidelines in the diagnosis of pulmonary embolism.

研究组 & 干预措施
Visualized pulmonary embolism computer task model
This group of participants was presented and trained to use a visual representation of diagnostic pathway for pulmonary embolism. The design of this visual representation is based on Bayes theorem and cognition enhancing visual design principles.
干预措施: Visualized pulmonary embolism computer task model (Other)
Didactic review pulmonary embolism lecture
This group of participants was presented with a didactic lecture covering the diagnostic approach of pulmonary embolism.
干预措施: Didactic review lecture (Other)
结局指标

Concordance with medical diagnostic reasoning pathway for pulmonary embolism.
时间窗: Paper-based clinical case scenarios were completed within 2 hour after either intervention.
Concordance with medical diagnostic reasoning pathway for a case presentation suggestive of pulmonary embolism will be reflected by whether participants are stopping prematurely or proceeding with diagnostic steps inappropriately.
次要结局
