Pelvic Compression Device (Binder) Application Training in Medical Students: A Manikin Study

Correct application of external pelvic compression devices (binders) is crucial in managing multitrauma patients with suspected pelvic fractures to control hemorrhage. Yet, there is a lack of practical training standards for pelvic compression device application in medical school education.

This study aimed to evaluate simulation training of pelvic compression device application by medical students to determine the number of applications required to meet proficiency measured by correct application and timeliness.

This is an observational cross-sectional measurement study of a convenience sample of 132 volunteer senior medical students who participated in a 30-min theoretical and simulation training session on the application of pelvic compression devices. The study was conducted between January 1, 2020, and March 1, 2020. Two weeks after the training, the students performed 10 consecutive pelvic compression device applications, each followed by a 5-min feedback session break. Application step accuracy and timing were observed and recorded. The percentage of correct applications was compared by χ2 test.

The correct application rate for the first application was 42.4%, with an average of 92 s, 95% confidence interval (CI): 91.00-93.72. The highest correct application rate occurred in the eighth application (97%, p < .001), with an average application time of 87 s, 95% CI: 85.62-87.72.

We found that at least eight pelvic compression device manikin applications were required to achieve proficiency.
