目的 评价共享心理模型(shared mental models, SMM)理论在医学生心肺复苏实践教学中的应用效果。方法 2024年4月,将中国医科大学2024年度春季学期选修“心肺复苏和体外自动除颤仪实践教育”课程的2021级63名本科生作为研究对象,按选课日期分为试验组(33人)和对照组(30人),试验组采用基于SMM理论的实践教学方法,对照组采用传统教学方法,课后对两组学生进行技能考核。数据采用χ2检验、t检验和Mann-Whitney U检验进行分析。结果 试验组和对照组的适当按压频率百分比分别为(74.8±13.0)%、(58.1±21.7)%,试验组和对照组的胸外按压分数分别为(71.5±2.3)%、(67.5±4.4)%,其差异均具有统计学意义(均P<0.05)。结论 将基于SMM理论的实践教学方法应用于医学生心肺复苏培训有助于提高团队复苏质量。
Objective To explore the application effect of the shared mental model (SMM) theory in the practical learning of cardiopulmonary resuscitation (CPR) in medical students. Methods In April 2024, 63 undergraduates of grade 2021 from China Medical University who took the elective course “Cardiopulmonary Resuscitation and Automated External Defibrillator” in the spring semester of 2024 were enrolled and divided into experimental group (n=33) and control group (n=30) according to the date of course selection. The experimental group adopted the practical learning method based on the SMM theory, while the control group adopted the traditional teaching method. After class, the two groups of students were assessed for their skills. For data analysis, χ2 test, t test, and Mann-Whitney U test were used. Results The percentage of appropriate pressing frequency in the experimental and control groups were (74.8±13.0)%, (58.1±21.7)%. The chest compression fraction in the experimental and control groups were (71.5±2.3)% and (67.5±4.4)%, both P<0.05. Conclusions Applying the practical learning method based on SMM theory to medical student CPR training helps to improve the quality of resuscitation in teams.
