The quality of podium presentations at the american society of colon and rectal surgeons: does a decade make a difference?

PURPOSE

The technology of the seven-minute scientific presentation has changed greatly with the universal acceptance of computerized slides and graphics. We performed this study to see whether the quality of delivery has improved pari passu with technical advances in presentation of data.

METHODS

In 1993 and in 2003 a sample of the podium presentations given at The American Society of Colon and Rectal Surgeons annual scientific meeting was analyzed. Number of slides, type of slides, time of presentation, and quality of presentation were recorded. Quality was scored by the presence of poor presentation techniques such as presenting too fast for the slide to be comprehended, presenting data that were different to what was on the slide, using fonts that were too small to be read, and reading the exact wording of the slide. One point was awarded for each transgression and for any talk lasting more than 7.9 minutes; the higher the score, the worse the presentation.

RESULTS

Thirty-eight presentations were analyzed from the 1993 meeting in Orlando and 40 were analyzed from the 2003 meeting in New Orleans. There was no difference in mean time of the presentation (1993, 7.5 minutes +/- 1.5 standard deviation vs. 2003, 7.2 minutes +/- 0.7 standard deviation), in mean number of slides used per presentation (1993, 16.4 +/- 3.3 standard deviation vs. 2003, 17.1 +/- 5.4 standard deviation), or in slides per minute (1993, 2.3 +/- 0.8 standard deviation vs. 2003, 2.5 +/- 1.0 standard deviation). Presentation technique was much worse in 1993, however, with a mean quality score of 2.2 +/- 1.1 standard deviation vs. 0.8 +/- 0.9 standard deviation in 2003 (P < 0.001). The most common fault in both years was presenting a slide too rapidly, a fault more pervasive in 1993 than in 2003 (1993, 30/38 presentations vs. 2003, 16/40). Only ten presentations went over the allotted time in 2003, by an average of one minute. In 1993, 18 presentations were too long, by an average of 1.8 minutes each.

CONCLUSIONS

The basic structure of the seven-minute podium presentation has changed little over the last ten years, despite major advances in technology. The most notable improvements have been in the technique of delivering the talk.
