My Google Reader accidentally picked up an intriguing abstract that examined a research study of resources that medical students use in solving diagnostic cases. The abstract was picked up because it contained the word “exercise” that is one of my PubMed filter queries. Although we often think that most diagnostic decision-making occurs from learned information stored in physician’s brains, information resources can be very helpful. What information resources are medical students using to help them with the diagnostic process?Graber and colleagues asked this question and designed a learning experiment. One hundred and seventeen medical students were presented a challenging case and asked to provide their top three diagnoses as well as listing all the resources they used and the helpfulness of each resource. This experiment occurred as part of a examination of the web-based decision support system known as Isabel. The top six most used resources (and the percent of medical students who used the resource in the experiment) were:
- Medical books (73%)
- Google (70%)
- Other students (69%)
- Journals (49%)
- Residents and attending (29%)
- Isabel (28%)
