The aim of this review was to evaluate the effectiveness of medical skills laboratories or simulators. In particular, it aimed to determine if performance in medical skills laboratories is transferable to actual clinical performance and maintained over time.
A range of databases was utilised to search for relevant papers published from 1998 to June 2006. Articles were included in the review if they met a number of criteria that included the evaluation of a skills laboratory or simulator for the purpose of procedural skills training, that participants were either undergraduate medical students or postgraduate medical trainees, and that the study used a randomised, controlled trial (RCT) research design in evaluation.
A total of 44 RCTs were identified for inclusion in the review. Overall, 32 (70%) studies reported that simulator training significantly improved procedural skills performance in comparison with standard or no training. Twenty (45%) RCTs assessed the transfer of simulator performance to clinical skills performance; however, 8 of these used animal models, not real patients. Only 2 studies assessed the maintenance of skills post-intervention, both at 4-month follow-up periods.
Medical skills laboratories do lead to improvement in procedural skills compared with standard or no training at all when assessed by simulator performance and immediately post-training. However, there is a lack of well designed trials addressing the crucial issues of transferability to clinical practice and retention of skills over time. Further research must be carried out to address these matters if medical skills laboratories are to remain an integral component of medical education.
本综述旨在评估医学技能实验室或模拟器的有效性。具体而言,其目的是确定在医学技能实验室中的表现是否可转化为实际临床操作表现,并随时间保持。
利用一系列数据库检索1998年至2006年6月发表的相关论文。如果文章符合多项标准,包括为程序技能培训目的评估技能实验室或模拟器、参与者为本科医学生或研究生医学实习生,且研究在评估中采用随机对照试验(RCT)研究设计,则纳入本综述。
共确定44项RCT纳入本综述。总体而言,32项(70%)研究报告称,与标准培训或无培训相比,模拟器培训显著提高了程序技能表现。20项(约45%)RCT评估了模拟器表现向临床技能表现的转化;然而,其中8项使用动物模型而非真实患者。只有2项研究在4个月的随访期评估了干预后技能的维持情况。
通过模拟器表现评估以及在培训后立即评估,与标准培训或根本不培训相比,医学技能实验室确实能提高程序技能。然而,缺乏精心设计的试验来解决向临床实践转化以及技能随时间保持的关键问题。如果医学技能实验室要继续成为医学教育的一个组成部分,必须开展进一步研究来解决这些问题。
