The effects of retraining on theoretical knowledge of cardiopulmonary resuscitation: a simple statistical method of evaluation.
Purpose: Retraining improves practical abilities in cardiopulmonary resuscitation (CPR). This work aims to evaluate the impact of retraining on theoretical knowledge of CPR. If any effects were identified, the role of notional concepts would be pointed out, beside the importance of practical exercises, and new approaches could be developed to make retraining more effective.
Materials and methods: During 2016 and early 2017, CPR courses were held according to 2015 guidelines and 226 student nurses (age:19-34, median=21) were enrolled. For 122 nurses, it was a retraining course (RC); the others attended their first course (FC). All participants completed a 7-question pre-test, regarding airways (items 1,3), breathing (4), circulation (5), defibrillation (6,7); chain of survival (2). After lessons, the same test was administered (post-test). Practical work was conducted on Resusci-Anne manikins with training defibrillators. R statistical program was used.
Results: Median pre-test score was 6 (range: 1-7). Median scores were 4.5 (range: 1-7) and 6 (range: 2-7), respectively in FC and RC group. A significant difference exists between the two groups (Mann-Whitney-Wilcoxon test, P
