Cardiology grand rounds: effect of videoconferencing on educational value

We studied four cardiology grand rounds transmitted by videoconference from a tertiary care centre to four other hospitals in eastern Canada. We collected data with evaluation questionnaires and by video recording participants at the receiving-site and the presentation they received from the presenting site. Receiving-site participants (n=20) rated their satisfaction with all domains significantly lower than did presenting-site participants (n=49). The greatest difference in ratings was in the ability to see slides (receiving sites 2.6/5, presenting site 4.6/5). Review of video recordings revealed that slides showing material copied from print sources was difficult to read at receiving sites. While 56% of discussion time was devoted to questions from receiving sites, participants there rated their ability to participate in discussion lower than those at the presenting site (3.9/5 vs 4.4/5). This may be because some parts of the discussion from the presenting site were not transmitted. Receiving-site participants rated the educational value of the rounds lower than their presenting-site colleagues (3.9/5 vs 4.4/5) but answered a similar percentage of knowledge questions correctly (85 vs 89%).
