Introduction: Given the critical nature of cardiac arrest during pregnancy and the limited experience of emergency medical staff in managing such cases, a suitable educational approach is needed to improve their knowledge and skills.
Objective: The present study aimed to evaluate the impact of peer education through the jigsaw method on the knowledge and performance of emergency medical personnel in delivering basic resuscitation for pregnant women at selected Aja hospitals.
Material and Methods: This semi-experimental study was conducted in 2022 on 48 emergency medicine assistants at a selected Aja hospital. Participants were divided into intervention and control groups (24 each) using a simple random method. The intervention group was trained using the jigsaw puzzle method, while the control group received traditional training. Knowledge and performance assessments were conducted at three points: before, immediately after, and three months post-intervention, using a questionnaire and checklist. Data were analyzed with descriptive and inferential statistics via SPSS version 26, with a significance level of 0.05.
Results: Knowledge scores in the intervention group (18.25±1.07) were significantly higher than those in the control group (16.75±1.79) immediately after training (P=0.001) and sustained this difference at three months post-intervention (16.41 ± 1.13 in the intervention group vs. 14.33±2.11 in the control group, P= 0.000). The improvement in knowledge scores was statistically significant across all time points (P= 0.003). Similarly, the performance scores of the intervention group (98.95 ± 4.64) surpassed those of the control group (88.12±5.48) immediately postintervention (P<0.0001) and remained higher after three months (86.91±5.70 vs. 78.62± 7.64, P<0.0001). Pre-test scores showed no significant differences between the groups. 
Conclusion: The jigsaw puzzle-based peer education approach significantly enhances and maintains the knowledge and practical skills necessary for performing basic cardiopulmonary resuscitation on pregnant women. This method is recommended as an effective training tool to bolster emergency medical response.
