Pleural procedures may cause serious complications when incorrectly carried out. There is a need to find effective methods for teaching how to insert a chest drain safely.
To assess the effectiveness of a programme for teaching chest tube insertion using a simulation model (SuperAnnie).
Groups of four to six junior doctors were enrolled in a 2-h teaching session, covering both theoretical knowledge and practical chest tube insertion techniques using a simulation model. Before the teaching module, participants completed a questionnaire about their confidence and skill levels and were videotaped inserting a standard chest tube in the model. The assessments were repeated 1 month after the teaching module. The video clips were scored by two independent assessors using an 18-point scoring system that was blinded to whether the taping was pre- or post-teaching.
Forty-nine doctors completed the study. Baseline video assessment scores were low (median score 4 (maximum possible score 18), interquartile range (IQR) 2-7.5) and were not associated with past experience, the doctor's self-confidence level or their self-assessed skill rating. After teaching, video assessment scores improved significantly (mean score 13, IQR 10.5-15). Doctors with the lowest baseline scores showed the most improvement. There were also improvements in doctors' self-confidence and self-assessed skill levels, although there remained no association between these measures and video assessment scores.
A brief teaching module using a simulation model is effective in improving confidence and skill in chest tube insertion.
胸膜操作若执行不当可能导致严重并发症。因此需要找到安全插入胸腔引流管的有效教学方法。
评估使用模拟模型(超级安妮)进行胸腔引流管插入教学项目的有效性。
将四至六名初级医生分为一组,参加为期2小时的教学课程,内容涵盖理论知识以及使用模拟模型进行胸腔引流管插入的实践技术。在教学模块开始前,参与者完成一份关于其信心和技能水平的问卷,并在模型中插入标准胸腔引流管时进行录像。在教学模块结束1个月后重复进行评估。由两名独立评估人员使用18分评分系统对视频片段进行评分,评分时不知道录像时间是教学前还是教学后。
49名医生完成了研究。基线视频评估分数较低(中位数为4分(满分18分)四分位间距(IQR)为2 - 7.5),且与既往经验、医生的自信水平或自我评估的技能等级无关。教学后,视频评估分数显著提高(平均分数为13分,IQR为10.5 - 15)。基线分数最低的医生进步最大。医生的自信心和自我评估的技能水平也有所提高,尽管这些指标与视频评估分数之间仍然没有关联。
使用模拟模型的简短教学模块可有效提高胸腔引流管插入的信心和技能。
