Teaching technical skills to medical students during a surgery clerkship: results of a small group curriculum.

BACKGROUND

Opportunities for medical students to learn and perform technical skills during their clinical years have decreased. Alternative means to provide instruction are increasingly important.

METHODS

Third-year students were assigned to three weekly small group tutorial sessions during their surgery clerkship. One hour sessions covered the following: suturing/knot tying, tubes (Foley catheter/NG tube), and lines (i.v. placement/arterial puncture). Students used a self-reported checklist to report their experience performing these procedures in the hospital after being exposed to them in the skills sessions. These data were compared with results prior to the implementation of the skills curriculum. Results were compared by Fisher's exact test.

RESULTS

Seventy-seven students had evaluable checklists during the control period, and 69 were evaluable during the study period. Participations in four specific skills were compared: Foley catheter placement, nasogastric tube insertion/removal, i.v. placement, and arterial stick. In all four skills, students were more likely to have performed the task after having been introduced to it in the skills sessions. For both Foley catheter placement (96% versus 90%; P = 0.05) and NG tube insertion/removal (70% versus 53%; P = 0.06) there was a trend toward a higher incidence of participation, although statistical significance was not met. However, for both IV placement (64% versus 18%; P = 0.0001) and arterial puncture (48% versus 18%; P = 0.0002) there were significant increases in participation between the study periods.

CONCLUSIONS

These results suggest that a small group technical skills curriculum facilitates learning of specific technical skills and appears to increase participation in all of the skills taught and assessed. This may be one strategy to introduce students to technical skills during the surgery clerkship and improve participation of these skills in the hospital setting.
