针对本科生骨牵引综合技能训练的双Debriefer混合模拟教学

Application of an innovational hybrid simulation-based education of bone traction with co-Debriefer for medical students

目的开发一种用于本科生骨牵引临床技能训练的双Debriefer混合模拟教学课程,并评价其教学效果。方法本研究采用交叉对照研究法。2018年6月至2019年6月,28名临床医学专业本科实习生被随机分为两组,分别以模拟教学和传统教学组织教学,1周后两组的教学方法进行交叉。用技能评分表评价学生在接受不同教学后的骨牵引临床技能水平。采用SPSS 23.0软件进行统计分析。结果在实习第1周末,实验组学生的技能评分高于对照组,平均分分别为85.07分、67.92分。在实习第2周末,实验组技能评分无明显变化;而对照组评分提升,并与实验组相比,差异无统计学意义。结论双Debriefer混合模拟教学为本科生学习骨牵引临床技能提供了新的可靠方法,能有效帮助学生提高技能,减少操作错误,保障患者安全。

Objective To develop an innovational hybrid simulation-based education of bone traction with co-Debriefer for medical students and to evaluate its effectiveness.Methods This study was designed as a cross-controlled study.From June 2018 to June 2019,28 medical students were randomized into two groups.The two groups adopted simulation-based education and traditional teaching method respectively.In the second week of internship,the teaching methods of the two groups exchanged.Scores rating of the skill were used to assess the students'performance in the end of each teaching methods.SPSS 23.0 software was used to analyze the collected data.Results In the first weekend of orthopedic-internship,students in the experimental group scored significantly higher than the control group,with an average score of 85.07 points versus 67.92 points.In the second weekend of practice,there was no obvious change in the skill score of the experimental group,but the score of the control group was significantly improved,and there was no obvious difference with the experimental group.Conclusion The hybrid simulation-based education with co-debriefing is a reliable teaching method for medical interns to learn skills of bone traction,which can effectively help improve students'skills,reduce their errors,and ensure patient's safety.
