Different ways to present clinical cases in a classroom: video projection versus live representation of a simulated clinical scene with actors

Table 1 Comparison of scores obtained on the questionnaires of knowledge about delirium before and after the seminar in both groups and between groups

*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)
**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)]
^aComplete questionnaire can be obtained in the supplementary appendix S1 of a previous publication [6]
Ɨ Average increase in questionnaire score after the seminar
ƗƗ > 0.80 signifies large change
