A systematic review of medical skills laboratory training: where to from here?

Abstract

Objectives: 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.

Methods: 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.

Results: 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.

Conclusions: 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.
