Tutoring Trainees to Suture: An Alternative Method for Learning How to Suture and a Way to Compensate for a Lack of...

Tutoring in suturing was developed to compensate for a shortage of suturing cases. The objective of this study was to compare ideal suturing score (ISS; 9 points), suturing time (min:sec), and suture placement error (mm) between medical students completing the suturing tutoring program and medical students attending ordinary medical school training program.

Participants consisted of 2 groups of medical students who had never performed suturing. The study group had the role of suturing tutor to teach interested high school students. The control group consisted of volunteers from the ordinary medical school program. Skills measurement was performed by having students from both the groups perform 3 vertical mattress sutures on a model. The study group was tested at weeks 1, 9, and 10 to assess improvement. Both the groups were tested at week 10 to compare final learning outcome.

There were 41 and 40 participants in the study group and the control group, respectively. ISS was significantly improved in the study group from week 1-week 10 (7.0 ± 1.3 vs. 8.2 ± 0.9, p = 0.01). At week 10, the study group had a higher mean ISS than the control group (8.2 ± 0.9 vs. 7.8 ± 1.1, p = 0.68). Mean suturing time and mean placement error were also lower in the study group at the end of suturing training (5:1 ± 1:0 vs. 5:2 ± 1:2, p = 0.13; 7.4 ± 7.4 vs. 8.0 ± 10.8, p = 0.44).

Tutoring trainees to suture can improve a student's ability to learn how to suture.
