目的 评价以情景病例为基础的模拟教学在住院医师机械通气培训中的应用效果。方法 以建构主义理论为基础构建情景病例和模拟培训系统。选择2016年1月~2018年5月在北京大学人民医院重症医学科轮转的86名住院医师为研究对象,采用随机数字表法将其平均分为实验组和对照组,每组43名医师。实验组采用情景病例模拟教学,对照组采用传统理论教学。培训前后,采用该培训规定的理论和操作评估体系对两组医师进行考核,并在轮转结束后进行培训满意度调查。结果 培训后所有医师考核总成绩为(80.5±8.3)分,高于培训前的(53.0±5.3)分,差异具有统计学意义(P<0.01);培训后实验组医师考核总成绩高于对照组医师[(87.1±5.8)分比(73.8±4.1)分],差异具有统计学意义(P<0.01)。实验组医师满意度评分为(44.5±1.9)分,高于对照组医师的(32.9±2.7)分,差异具有统计学意义(P<0.01)。结论 在机械通气教学中应用以情景病例为基础的模拟培训取得了较好的效果,获得了较高的满意度。
Objective To evaluate the effectiveness and satisfaction of scenario cases based simulation teaching in the training of mechanical ventilation.Methods The scenario cases and simulation courses based on constructionism were developed in the residents.Eighty-six residents who rotated to intensive care unit from January 2016 to May 2018 were randomized to experimental group and control group.Forty-three experimental group residents were trained using scenario cases based simulation teaching,and the other forty-three control group residents were trained using traditional teaching.Theory and operation assessment were compared between two groups before and after training.Training satisfaction was also compared between two groups after rotation in the department of Critical Care Medicine.Results Total test score of post-training was significantly higher than that of pre-training in all the residents (80.5±8.3 vs 53.0±5.3,P<0.01).After training,total test score was significantly higher in the experimental group than control group (87.1± 5.8 vs 73.8± 4.1,P<0.01).Training satisfaction was also significantly higher in the experimental group than that in control group (44.5± 1.9 vs 32.9± 2.7,P<0.01).Conclusions The application of scenario cases based simulation teaching in mechanical ventilation training had achieved good results and high satisfaction.
