Visually diagnosed medical tests (e.g. radiographs) are the most commonly ordered tests in front-line medicine. As such, front-line health care professionals are faced with the task of learning the skill of interpreting these images to an expert performance level by the time they provide opinions that guide patient management decisions. However, discordant interpretations of these images between front-line physicians and expert counterparts (e.g. radiologists) is a common cause of medical error. In paediatrics, this problem is even greater due to the changing physiology with age leading to increased risk of interpretation errors.
ImageSim provides a comprehensive and evidence-based on-line education system that teaches health care professionals the interpretation of visually diagnosed medical tests using the concepts of deliberate practice and simulation. That is, our learning model includes sustained active practice of hundreds of cases where the learner is forced to commit to diagnosis for every case and then receives immediate specific feedback on their interpretation so that the participant instantly learns from each case. Importantly, we have presented these images as we encounter them in practice, and included a normal to abnormal radiograph ratio (with a spectrum of pathology) reflective of our day-to-day practice.
Our research to date shows that this learning method works – and all physicians at varying levels of expertise had significantly increased their accuracy in image interpretation along a “learning curve” as graphed below:
We started this system for paediatric musculoskeletal images, and our participants enjoyed it and asked us for more. We now have three live courses and are actively developing several more.
