Abstract

Abstract:

Objective

To establish a prediction model of cardiopulmonary resuscitation skill performance for medical students based on internship data.

Methods

A retrospective study among interns in the Second Affiliated Hospital of Guangzhou Medical University was conducted from Jan 2016 to Dec 2018. Data including students' test scores during internship, gender, and CPR skill performance of objective structured clinical examination of graduation was collected. Logistic regression analysis was used to develop the prediction model of cardiopulmonary resuscitation skill performance.

Results

382 cases of medical students' data were analyzed. A prediction model was developed and consisted of five parameters: surgery case score, surgical theory test score, obstetrics theory test score, pediatric theory test score, gender. Odds ratio of "gender is female" was 0.58 (95% CI: 0.36-0.92), and Odds ratios of the other variables were between 0.90 and 1. The AUC of the prediction model was 64.8% (95% CI: 0.59-0.71)

Conclusion

Gender might be an influencing factor of CPR skill performance. The predictive performance of the CPR skill performance prediction model still needs to be improved.

Key words: Cardiopulmonary resuscitation, Student performance prediction model, Objective structured clinical examination
