Features and uses of high-fidelity medical simulations that lead to effective learning: a BEME systematic review
TL;DR: While research in this field needs improvement in terms of rigor and quality, high-fidelity medical simulations are educationally effective and simulation-based education complements medical education in patient care settings.
Abstract: SUMMARY Review date: 1969 to 2003, 34 years. Background and context: Simulations are now in widespread use in medical education and medical personnel evaluation. Outcomes research on the use and effectiveness of simulation technology in medical education is scattered, inconsistent and varies widely in methodological rigor and substantive focus. Objectives: Review and synthesize existing evidence in educational science that addresses the question, ‘What are the features and uses of high-fidelity medical simulations that lead to most effective learning?’. Search strategy: The search covered five literature databases (ERIC, MEDLINE, PsycINFO, Web of Science and Timelit) and employed 91 single search terms and concepts and their Boolean combinations. Hand searching, Internet searches and attention to the ‘grey literature’ were also used. The aim was to perform the most thorough literature search possible of peer-reviewed publications and reports in the unpublished literature that have been judged for academic quality. Inclusion and exclusion criteria: Four screening criteria were used to reduce the initial pool of 670 journal articles to a focused set of 109 studies: (a) elimination of review articles in favor of empirical studies; (b) use of a simulator as an educational assessment or intervention with learner outcomes measured quantitatively; (c) comparative research, either experimental or quasi-experimental; and (d) research that involves simulation as an educational intervention. Data extraction: Data were extracted systematically from the 109 eligible journal articles by independent coders. Each coder used a standardized data extraction protocol. Data synthesis: Qualitative data synthesis and tabular presentation of research methods and outcomes were used. Heterogeneity of research designs, educational interventions, outcome measures and timeframe precluded data synthesis using meta-analysis. Headline results: Coding accuracy for features of the journal articles is high. The extant quality of the published research is generally weak. The weight of the best available evidence suggests that high-fidelity medical simulations facilitate learning under the right conditions. These include the following:

TL;DR: This article reviews and critically evaluates historical and contemporary research on simulation‐based medical education (SBME) and presents and discusses 12 features and best practices that teachers should know in order to use medical simulation technology to maximum educational benefit.
Abstract: Objectives This article reviews and critically evaluates historical and contemporary research on simulation-based medical education (SBME). It also presents and discusses 12 features and best practices of SBME that teachers should know in order to use medical simulation technology to maximum educational benefit.
Methods This qualitative synthesis of SBME research and scholarship was carried out in two stages. Firstly, we summarised the results of three SBME research reviews covering the years 1969–2003. Secondly, we performed a selective, critical review of SBME research and scholarship published during 2003–2009.
Results The historical and contemporary research synthesis is reported to inform the medical education community about 12 features and best practices of SBME: (i) feedback; (ii) deliberate practice; (iii) curriculum integration; (iv) outcome measurement; (v) simulation fidelity; (vi) skill acquisition and maintenance; (vii) mastery learning; (viii) transfer to practice; (ix) team training; (x) high-stakes testing; (xi) instructor training, and (xii) educational and professional context. Each of these is discussed in the light of available evidence. The scientific quality of contemporary SBME research is much improved compared with the historical record.
Conclusions Development of and research into SBME have grown and matured over the past 40 years on substantive and methodological grounds. We believe the impact and educational utility of SBME are likely to increase in the future. More thematic programmes of research are needed. Simulation-based medical education is a complex service intervention that needs to be planned and practised with attention to organisational contexts.

TL;DR: In comparison with no intervention, technology-enhanced simulation training in health professions education is consistently associated with large effects for outcomes of knowledge, skills, and behaviors and moderate effects for patient-related outcomes.
Abstract: Context Although technology-enhanced simulation has widespread appeal, its effectiveness remains uncertain. A comprehensive synthesis of evidence may inform the use of simulation in health professions education. Objective To summarize the outcomes of technology-enhanced simulation training for health professions learners in comparison with no intervention. Data Source Systematic search of MEDLINE, EMBASE, CINAHL, ERIC, PsychINFO, Scopus, key journals, and previous review bibliographies through May 2011. Study Selection Original research in any language evaluating simulation compared with no intervention for training practicing and student physicians, nurses, dentists, and other health care professionals. Data Extraction Reviewers working in duplicate evaluated quality and abstracted information on learners, instructional design (curricular integration, distributing training over multiple days, feedback, mastery learning, and repetitive practice), and outcomes. We coded skills (performance in a test setting) separately for time, process, and product measures, and similarly classified patient care behaviors. Data Synthesis From a pool of 10 903 articles, we identified 609 eligible studies enrolling 35 226 trainees. Of these, 137 were randomized studies, 67 were nonrandomized studies with 2 or more groups, and 405 used a single-group pretest-posttest design. We pooled effect sizes using random effects. Heterogeneity was large (I2>50%) in all main analyses. In comparison with no intervention, pooled effect sizes were 1.20 (95% CI, 1.04-1.35) for knowledge outcomes (n = 118 studies), 1.14 (95% CI, 1.03-1.25) for time skills (n = 210), 1.09 (95% CI, 1.03-1.16) for process skills (n = 426), 1.18 (95% CI, 0.98-1.37) for product skills (n = 54), 0.79 (95% CI, 0.47-1.10) for time behaviors (n = 20), 0.81 (95% CI, 0.66-0.96) for other behaviors (n = 50), and 0.50 (95% CI, 0.34-0.66) for direct effects on patients (n = 32). Subgroup analyses revealed no consistent statistically significant interactions between simulation training and instructional design features or study quality. Conclusion In comparison with no intervention, technology-enhanced simulation training in health professions education is consistently associated with large effects for outcomes of knowledge, skills, and behaviors and moderate effects for patient-related outcomes.

TL;DR: Internet-based learning is associated with large positive effects compared with no intervention and with non-Internet instructional methods, suggesting effectiveness similar to traditional methods.
Abstract: Context The increasing use of Internet-based learning in health professions education may be informed by a timely, comprehensive synthesis of evidence of effectiveness. Objectives To summarize the effect of Internet-based instruction for health professions learners compared with no intervention and with non-Internet interventions. Data Sources Systematic search of MEDLINE, Scopus, CINAHL, EMBASE, ERIC, TimeLit, Web of Science, Dissertation Abstracts, and the University of Toronto Research and Development Resource Base from 1990 through 2007. Study Selection Studies in any language quantifying the association of Internet-based instruction and educational outcomes for practicing and student physicians, nurses, pharmacists, dentists, and other health care professionals compared with a no-intervention or non-Internet control group or a preintervention assessment. Data Extraction Two reviewers independently evaluated study quality and abstracted information including characteristics of learners, learning setting, and intervention (including level of interactivity, practice exercises, online discussion, and duration). Data Synthesis There were 201 eligible studies. Heterogeneity in results across studies was large (I2 ≥ 79%) in all analyses. Effect sizes were pooled using a random effects model. The pooled effect size in comparison to no intervention favored Internet-based interventions and was 1.00 (95% confidence interval [CI], 0.90-1.10; P Conclusions Internet-based learning is associated with large positive effects compared with no intervention. In contrast, effects compared with non-Internet instructional methods are heterogeneous and generally small, suggesting effectiveness similar to traditional methods. Future research should directly compare different Internet-based interventions.

TL;DR: This study was undertaken to determine whether or not breadth of clinical experience and student levels of confidence were indicators of competency on standardized simulator performance‐based assessments.
Abstract: Objectives This study was undertaken to determine whether or not breadth of clinical experience and student levels of confidence were indicators of competency on standardized simulator performance-based assessments.
Methods All students (n=144) attending an educational session were asked to complete a 25-point questionnaire regarding specific clinical experiences and levels of confidence in their ability to manage patient problems. For enumeration of clinical experiences, students were asked to estimate the number of times a situation had been encountered or a skill had been performed. For level of confidence, each response was based on a 5-point Likert scale where 1=novice and 5=expert. Students then participated in a standardized simulated performance test. Median and range were calculated and data analysed using Spearman rank correlations. A P-value <0·05 was considered significant. Level of confidence data were compared to performance during clinical rotation and to marks in the anaesthesia final examination.
Results A total of 144 students attended the session, completed the questionnaire and participated in the standardized test. There were wide ranges of experience and confidence in the 25 listed items. Analysis of data showed good correlation between clinical experience and level of confidence. There was no correlation between clinical experience, level of confidence and performance in a standardized simulation test. Neither was there any correlation between level of confidence and clinical grades or written examination marks.
Conclusions Clinical experience and level of confidence have no predictive value in performance assessments when using standardized anaesthesia simulation scenarios.

TL;DR: Psychomotor skillsimprove after training on both VR and VT, and skills may be transferable, and training on a minimally invasive surgery trainer, virtual reality system may improve operative performance during laparoscopic cholecystectomy.
Abstract: Training on a video trainer or computer-based minimally invasive surgery trainer leads to improved benchtop laparoscopic skill. Recently, improved operative performance from practice on a video trainer was reported. The purpose of this study was three fold: (a) to compare psychomotor skill improvement after training on a virtual reality (VR) system with that after training on a video-trainer, (VT) (b) to evaluate whether skills learned on the one training system are transferable to the other, and (c) to evaluate whether VR or VT training improves operative performance. For the study, 50 junior surgery residents completed baseline skill testing on both the VR and VT systems. These subjects then were randomized to either a VR or VT structured training group. After practice, the subjects were tested again on their VR and VT skills. To assess the effect of practice on operative performance, all second-year residents (n = 19) were evaluated on their operative performance during a laparoscopic cholecystectomy before and after skill training. Data are expressed as percentage of improvement in mean score/time. Analysis was performed by Student's paired t-test. The VR training group showed improvement of 54% on the VR posttest, as compared with 55% improvement by the VT group. The VR training group improved more on the VT posttest tasks (36%) than the VT training group improved on the VR posttest tasks (17%) (p <0.05). Operative performance improved only in the VR training group (p <0.05). Psychomotor skillsimprove after training on both VR and VT, and skills may be transferable. Furthermore, training on a minimally invasive surgery trainer, virtual reality system may improve operative performance during laparoscopic cholecystectomy.

TL;DR: The training of novices using the Minimal Invasive Surgical Trainer in Virtual Reality yields quantifiable changes in skill that are transferable to a simple real task and are similar to the results achieved with conventional training.
Abstract: Background: To validate the usefulness of virtual reality surgical simulators, we investigated the transfer of skills achieved by their use to real tasks. Methods: Thirty medical students underwent a pretest using a real laparoscopic trainer. They were then randomized to the following three groups: group I received no training; group II received training using the Minimal Invasive Surgical Trainer in Virtual Reality (MIST-VR); and group III received training using conventional training exercises. Each group then underwent a posttest. Using the Imperial College Surgical Assessment Device (ICSAD), scores were generated for time taken, distance traveled, number of movements made, and speed of instrument movement. Results: Significant changes between the MIST-VR group (group II) and the conventionally trained group (group III), were observed in the speed of movement of the left hand and the numbers of movements taken by each hand, when compared to the untrained group (group I). Conclusion: The training of novices using MIST-VR yields quantifiable changes in skill that are transferable to a simple real task and are similar to the results achieved with conventional training.

TL;DR: The results of the experiment suggest unequivocally that there is a twofold advantage to the use of such a simulator in training anesthesiology residents in the skill of endotracheal intubation: (a)Residents achieve proficiency levels in a smaller number of elapsed days of training, thus effecting a saving of time in the training of personnel, and (b) residents achieve a proficiency level in a small number of trials in the operating room, thus posing significantly less threat to patient safety.
Abstract: The educational potential of a computer-controlled patient simulator was tested by the University of Southern California School of Medicine. The results of the experiment suggest unequivocally that there is a twofold advantage to the use of such a simulator in training anesthesiology residents in the skill of endotracheal intubation: (a) residents achieve proficiency levels in a smaller number of elapsed days of training, thus effecting a saving of time in the training of personnel, and (b) residents achieve a proficiency level in a smaller number of trials in the operating room, thus posing significantly less threat to patient safety. The small number of subjects in the study and the large within-group variability were responsible for a lack of statistical significance in 4 of 6 of the analyses performed; however, all differences were substantial and in the hypothesized direction. Thus, despite the narrowly circumscribed tasks to be learned by the experimental subjects, the findings suggest that the use of simulation devices should be considered in planning for future education and training not only in medicine but in other health care professions as well.
