  1. *Four theoretical questions about delirium; definition (range 0–2 points), describe predisposing factors (range 0–1 point), describe precipitating factors (range 0–2 points) and make a list of measures to improve and prevent progression of delirium (range 0–2 points)
  2. **Two subjective learning perception questions [to what degree would you be able to detect the risk of a confusional syndrome? (Linear scale from 0 to 10 points) and to what degree would you be able to advise a plan of interventions to prevent delirium in an elderly patient? (Linear scale from 0 to 10 points)]
  3. aComplete questionnaire can be obtained in the supplementary appendix S1 of a previous publication [6]
  4. Ɨ Average increase in questionnaire score after the seminar
  5. ƗƗ > 0.80 signifies large change
