Application of case-based scenario simulation teaching in cardiopulmonary resuscitation training for medical and nursing interns

Abstract Background To explore the application value of case-based scenario simulation teaching in CPR training for medical and nursing interns through a single-centre randomized controlled trial. Methods A total of 69 medical and nursing interns rotating at our hospital from September 2024 to November 2025 were selected. These interns were randomly assigned to either a control group ( n = 34) or a intervention group ( n = 35) using a random number table. The effectiveness of the teaching was evaluated through theoretical assessments, Mini-CEX scores, and questionnaire surveys. Results The theoretical scores of the control group were significantly lower than those of the intervention group (83.53 ± 5.42 vs. 90.89 ± 3.89, P < 0.05). Mini-CEX evaluation results showed that the intervention group scored significantly higher than the control group in knowledge mastery (7.97 ± 1.04 vs. 4.82 ± 1.24, P < 0.05), operational skills (8.00 ± 0.64 vs. 4.88 ± 1.59, P < 0.05), clinical judgment (7.91 ± 0.78 vs. 4.24 ± 1.30, mean difference 3.67, 95% CI 3.10 to 4.24, P < 0.001), and team collaboration (8.14 ± 0.91 vs. 4.50 ± 1.10, P < 0.05). The total Mini-CEX score was also significantly higher in the intervention group (32.03 ± 2.18 vs. 18.44 ± 2.45, P < 0.05). Satisfaction survey results indicated that the intervention group was more satisfied with course content, course resources, classroom interaction, and teaching methods compared to the control group ( P < 0.05). Furthermore, there was no significant difference in learning burden between the two groups ( P > 0.05). Conclusion This single-centre randomized trial suggests that case-based scenario simulation teaching may improve immediate CPR educational outcomes among medical and nursing interns. Compared with conventional instruction, the intervention was associated with higher theoretical knowledge scores, better practical assessment performance, and greater satisfaction.
