Deliberate Practice in Simulation-Based Surgical Skills Training: A Scoping Review

BACKGROUND: In recent years there has been a shift from traditional Halstedian methods toward more simulation-based medical education (SBME) for developing surgical skills Questions remain about the role and value of SBME, although feedback and engagement in repetitive practice have been associated with positive learning outcomes. Regardless of approach, the principles of deliberate practice align with both the Halstedian traditions and ways of implementing SBME. Whilst deliberate practice is well described in the wider literature, the extent to which it is an effective instructional approach in surgical training remains unknown. OBJECTIVE: To explore the effectiveness of deliberate practice as an instructional design for developing surgical skills through SBME interventions, as assessed by improvements in trainee performance and/or patient outcomes. METHODS: A combined search was conducted in PUBMED, CINAHL, EMBASE, MEDLINE, PSYCHINFO, and Google Scholar. Three hundred one articles were screened and 17 met the inclusion criteria for analysis. RESULTS: There was heterogeneity of study methods with 6 randomized control trials, 7 pretest/post-test design, 2 nonrandomized comparisons and 2 observational studies. All articles demonstrated positive learner outcomes following SBME with deliberate practice, although there was no direct comparison to another instructional method. Two studies demonstrated skill transfer to the clinical environment and 1 demonstrated improved patient outcomes. CONCLUSION: Deliberate practice informed SBME interventions appeared effective for developing surgical skills among trainee surgeons, however the reliability of these conclusions was limited by the modest quality of the research studies and the design elements of deliberate practice were inconsistently applied. There was little evidence that deliberate practice led to skills retention beyond 30 days, although participant numbers were low and the quality of studies was modest.

Automated summary

The study examined the effectiveness of deliberate practice as an instructional design for developing surgical skills through SBME interventions. While the results showed that deliberate practice had a positive impact on trainee outcomes, limitations in research quality and inconsistent application of deliberate practice elements were identified.
