The Effect of Scenario-based and Participatory Method of Cardiopulmonary Resuscitation (CPR) Training on the Knowledge of Basic and Advanced Life Support (BLS and ACLS) in Emergency Medical Technicians.
Background: Despite running various training courses on cardiopulmonary resuscitation, emergency
medical technicians are still facing problems with insufficient knowledge to play a professional role in
management of CPR. Meanwhile, factors such as inefficiency of training method can have a detrimental
effect on their learning, and eventually their knowledge and skills in CPR.
Objective: The present study aimed to determine and compare the effect of scenario-based and participatory
method of cardiopulmonary resuscitation training on the knowledge of basic and advanced life support in
emergency medical technicians.
Methodology and Participants: A total of 90 emergency medical technicians participated in the present
quasi-experimental study (in three intervention groups of scenario-based, participatory and control). Block
randomization was utilized to allocate the participants to three intervention groups. A researcher-made test
including two sections of knowledge of basic and advanced life support (each one comprised 19 questions)
was used to collect data. All statistical analyzes were conducted using SPSS software version 16.0 (SPSS
Inc., Chicago, Ill., USA). The measure of central tendency and the Index of dispersion (mean and standard
deviation) were used to analyze the quantitative data and Kruskal-Wallis H test was used to compare mean
scores. A P value of less than 0.05 was considered statistically significant.
Results: The difference in knowledge mean scores of basic and advanced life support before the intervention
was not statistically significant between the three groups (P> 0.05). However, the difference was significant
between the three groups after the intervention (P <0.05).
Conclusion: Based on the results of our study, scenario-based training method has a significant effect
on improving the basic and advanced knowledge of CPR in emergency medical technicians compared to
