- Abstract
OBJECTIVE: To assess the effect of segmentation and user control on learning of basic surgical skills in a video-based instruction format as compared to nonsegmented video-based instruction format in novices. METHODS: This quasi-experimental study was conducted at Dow University of health sciences Karachi, Pakistan. Sixty students were divided into four groups of 15 each. Each group had a different method of instruction. Group A: nonsegmentation with facilitator; Group B: non-segmentation without facilitator; Group C: segmentation with no user control; Group D: segmentation with user control. All groups' knot tying skill was assessed at the end of session. Data analyzed using SPSS version-17. Kruskal Wallis and Mann-Whitney U tests were applied for data analysis. RESULTS: Out of 60 participants, sixteen (26.7%) were male and forty-four (73.3%) were female. Overall, scores on performance examination [p=0.006] were statistically significant. With respect to method of instruction, scores on performance examinations of group A and group B were statistically significant [D(15)=0.300, p=0.001] and [D(15)=0.225, p=0.040] respectively. Levine test was employed to assess the homogeneity of variance assumption. For performance scores, the variances were equal for all four group students (i.e. nonsignificant) [F (3,56) =1.68, p=0.182] and [F (3,56) =1.90, p=0.140] respectively]. Median performance scores were significantly higher in group A as compared to group D [U=45.50, r=-0.73, p=0.004]. CONCLUSION: Non-segmented video-based instructions with expert feedback result in increased learning of basic surgical as compared to segmentation with user control, in novice students. Both segmented and nonsegmented video resulted in similar amount of learning.
