A lack of preparedness for practice has been observed among new medical graduates. Simulation technology may offer one means of producing competency. This paper describes the application of a simulation-based intervention incorporating precision teaching (PT), a method of defining target skills, assessing individual progress and guiding instructional decisions, which is used to monitor learning and the development of behavioural fluency in other domains, to procedural skills training. Behavioural fluency refers to accurate and rapid responding that does not deteriorate with time, is resistant to distraction and can be adapted into new, more complex responses.
This study used a between-groups design to evaluate the efficacy of a simulation-based intervention incorporating PT for teaching venepuncture among 11 medical students. The intervention consisted of timed learning trials during which participants carried out the skill in pairs and received corrective feedback. Two control groups of 11 untrained medical students and 11 junior doctors were also included in the study.
Intervention group participants required an average of five trials and 21.9 min to reach the criterion for fluency. The intervention group demonstrated significantly higher accuracy in venepuncture performance than either control group. Improvements persisted over time, did not deteriorate during distraction, generalised to performance with patients and performance of an untargeted skill also improved.
The outcomes of this preliminary study support the application of PT within medical education. The implications of these data for clinical and procedural skills training are explored and suggestions are made for further research.
新毕业的医学专业学生在临床实践准备方面存在不足。模拟技术可能是培养能力的一种手段。本文描述了一种基于模拟的干预措施的应用,该措施结合了精准教学(PT),这是一种用于定义目标技能、评估个人进展并指导教学决策的方法,在其他领域用于监测学习和行为流畅性的发展,并将其应用于程序技能培训。行为流畅性是指准确、快速的反应,不会随着时间的推移而变差,能抵抗干扰,并且可以适应新的、更复杂的反应。
本研究采用组间设计,评估一种基于模拟并结合PT的干预措施对11名医学生进行静脉穿刺教学的效果。干预包括定时学习试验,在此期间参与者成对进行技能操作并接受纠正反馈。研究还纳入了两个对照组,分别为11名未受过训练的医学生和11名初级医生。
干预组参与者平均需要5次试验和21.9分钟才能达到流畅性标准。干预组在静脉穿刺操作中的准确性明显高于任何一个对照组。随着时间的推移,这种提高持续存在,在分心期间不会变差,能推广到对患者的操作中,并且一项非目标技能的操作也得到了改善。
这项初步研究的结果支持在医学教育中应用PT。探讨了这些数据对临床和程序技能培训的意义,并为进一步研究提出了建议。
