Effect of prebriefing in cardiopulmonary resuscitation education for laypeople on educational effectiveness and satisfaction

Bystander cardiopulmonary resuscitation (CPR) is important for improving survival rates and neurological outcomes in out -of -hospital cardiac arrest. However, laypeople often have psychological barriers to performing CPR, even if they have received training. Prebriefing provides psychological stability to the participants, enabling them to concentrate more comfortably during simulation. However, previous studies have mainly focused on simulationbased education for medical professionals, and no study has focused on prebriefing for laypeople. Therefore, we developed a structured prebriefing for laypeople and applied it to their CPR education to investigate its effect on educational effectiveness and satisfaction. This group randomization study was conducted from 09 November 2022 to 09 December 2022. Individuals aged >= 18 years who participated in CPR training as non -medical personnel were included. A 60 -min CPR education focusing on hands-on skills was conducted. The Prebriefing Experience Scale for laypersons (PESL) was developed and surveyed using a 5 -point Likert scale by modifying the Prebriefing Experience Scale for medical personnel based on existing research. During the study, a total of 382 people applied for education in 29 classes. Owing to logistical constraints resulting in randomization failure within the cohort of 10 classes, 82 participants were affected and subsequently excluded. In addition, 12 participants were excluded because of incomplete responses in the PESL survey. Ultimately, the experimental cohort consisted of 139 participants distributed across 10 classes, and the control group comprised 149 participants within the 9 classes. No difference in age and sex was found between the two groups. No statistically significant differences were observed between the two groups across all categories of the PESL assessment. In this study, when structured prebriefing was conducted on the general public, no statistically significant differences were found in PESL compared with conventional prebriefing. However, more improved research is needed.
