  1. Multimedia presentation of lung sounds as a learning aid for medical students.

    Article - En anglais

    New educational technologies might help to compensate for the decrease in time and emphasis dedicated to physical examination in medial training.

    This may, in particular, be applicable for improving the skills in auscultation of the chest.

    We investigated whether a multimedia presentation of acoustic and graphic characteristics of lung sounds could improve the learning of pulmonary auscultation by medical students, in comparison with conventional teaching methods.

    We studied 48 medical students without clinical experience, who had received conventional formal teaching on chest examination.

    Chest auscultation skills were evaluated using an inaccuracy score for the student's auscultation report on three patients, selected according to a standardized procedure.

    After a baseline evaluation, 27 students in groups of 5-10, participated in a multimedia seminar on lung sounds during which digitized lung sounds were played and the corresponding time-expanded waveform and frequency spectrum were commented on and displayed on a computer.

    The remaining 21 students received conventional bedside training, acting as control group.

    The following week, all the students underwent a second evaluation of chest auscultation skills.

    No differences in the inaccuracy score were observed between the two groups in the preliminyra test.
