Can a single interactive seminar durably improve knowledge and confidence of hospital diabetes management?

Abstract

BACKGROUND: Safe and effective diabetes management in the hospital is challenging. Inadequate knowledge has been identified by trainees as a key barrier. In this study we assess both the short-term and long-term impact of an interactive seminar on medical student knowledge and comfort with hospital diabetes management., METHODS: An interactive seminar covering hospital diabetes management and utilizing an audience response system was added to the third-year medical student curriculum. Students were given a multiple choice assessment immediately before and after the seminar to assess their comprehension of the material. Students were also asked to rate their confidence on this topic. Approximately 6 months later, students were given the same assessment to determine if the improvements in hospital diabetes knowledge and confidence were durable over time. Students from the preceding medical school class, who did not have a hospital diabetes seminar as a part of their curriculum, were used as a control., RESULTS: Fifty-three students participated in the short-term assessment immediately before and after the seminar. The mean score (maximum 15) was 7.7 +/- 2.7 (51%) on the pre-test and 11.4 +/- 1.8 (76%) on the post-test (p<0.01). 75 students who attended the seminar completed the same set of questions 6 months later with mean score of 9.2+/-2.3 (61%). The control group of 100 students who did not attend seminar had a mean score of 8.8+/-2.5 (58%). The difference in scores between the students 6-months after the seminar and the control group was not significantly different (p=0.30)., CONCLUSIONS: Despite initial short-term gains, a single seminar on hospital diabetes management did not durably improve trainee knowledge or confidence. Addition of repeated and focused interactions during clinical rotations or other sustained methods of exposure need to be evaluated.
