A prospective controlled trial of teaching basic surgical skills with 4th year medical students.
Scrubbing, gowning, gloving and aseptic technique are currently the only formal teaching 4th year medical students receive at the beginning of an 8-week surgery rotation. Teaching is often delegated to junior house staff and early bad habits are difficult to unlearn in post-graduate training. A study population of 4th year medical students from three hospitals were examined. At the beginning of an 8-week surgery rotation technical skills were tested with a simulation appendectomy model at the beginning and end of the surgery rotation. On day one, after a pre-test, a teaching intervention was alternated between two hospitals. A control group received only a post-test. The outcome measure was a cumulative score of the students' performance in technical stations in the simulation model. A comparison was made of the mean post-test scores in the teaching, non-teaching and control groups. An analysis of variance of all post-test scores rejected the null hypothesis at the 0.05 level. Duncan's multiple range test demonstrated a significant difference between the teaching and non-teaching group. Feedback from 25 students indicated the teaching model was practical and relevant. A formal teaching intervention of basic technical skills with 4th year medical students improved their performance on a simulated appendectomy model.
