The Comparison of the Knowledge of Emergency Medicine Interns in Management of common tachycardia before and after Model-Based training and Lecture: a semi-experimental study before and after the intervention
Cardiovascular disease is the most common cause of death, today. Tachycardia is usually a medical emergency that indicates cardiac dysrhythmia. The aim of this study was to compare the knowledge of emergency medicine interns in the management of common rapid heartbeats before and after training by model-based and lecture methods.
In this semi-experimental study, before and after the intervention, 122 emergency medicine interns were included in the study (2019). Students were randomly divided into two groups: model-based workshop (60 people) and lecture (62 people). The data collection tool in this study was a researcher-made questionnaire whose validity and reliability (Cronbach's alpha = 85%) were confirmed. The questionnaire was completed by both groups of students before the intervention and after the intervention. Data analysis was done using SPSS version 20 software and descriptive statistics (percentage, mean and standard deviation) and inferential tests (Mann-Whitney and Wilcoxon). In all calculations, the value of 0.05 was considered as a significant level.
The mean score of the tachycardia management test after training in the lecture group was 8.6± 9.1 points (out of 13 points). And the mean score of the management test of tachycardia, after training in the model-based workshop group, is equal to 5. It was 6.9±1.00 points (out of 13 marks). According to Mann-Whitney non-parametric test, there was a statistically significant difference in terms of the mean score of the pulse management test after training between the two groups of model-based workshop and lecture group (P = 0.001). Also, the mean score of the rapid-fire management test after training was higher in the model-oriented workshop group.
It seems that the use of model-based method (practical workshop with modeling and clinical scenario) can be more effective on the knowledge of emergency medicine practitioners in the management of common tachycardia before and after training than the lecture method. Therefore, using the model-based method can increase the knowledge of emergency medicine students.
