Can an Orthopedic Hip Fracture Simulator Advance Orthopedic Residents' Hip Fracture Fixation Skills to an Expert Level?

Abstract

Objective: This study was undertaken to evaluate hip fracture simulator training and orthopedic resident skill attainment. We hypothesized that after 6 training sessions, improvement in post-training scores in junior residents would exceed that of senior residents and that senior residents would attain expert level proficiency sooner.

Design: Thirty orthopedic residents from a single institution completed 6 training sessions. Sessions included a pretest, 9 training modules, and post-test. An expert score was obtained from the average scores of 8 trauma fellows and attending orthopedic traumatologists. The primary outcome measure was overall score.

Setting: A single academic institution.

Participants: Orthopedic residents (postgraduate years [PGYs] 1-5).

Results: Twenty-six residents completed the study. The mean overall post-training score was 87% of the expert level. Factors associated with post-training score changes were additional training sessions (4.2% improvement [p < 0.01]), time between training sessions (0.3% decrease [p = 0.05]) and PGY5 class (12.1% improvement [p = 0.03]). Fifty-four percent of residents attained the expert overall score. Expert score attainment was not associated with an additional year of training or case log volume. Post-training scores plateaued for the PGY1s and showed linear improvement for the PGY5s.

Conclusions: Differences in trends between training levels suggest this simulator is a useful adjunct to a 5-year orthopedic residency training program.
