Abstract
BACKGROUND:
The use of simulation in medical education is increasing, with students taught and assessed using simulated patients and manikins. Medical students at Queen's University of Belfast are taught advanced life support cardiopulmonary resuscitation as part of the undergraduate curriculum. Teaching and feedback in these skills have been developed in Queen's University with high-fidelity manikins. This study aimed to evaluate the effectiveness of video compared to verbal feedback in assessment of student cardiopulmonary resuscitation performance.
METHODS:
Final year students participated in this study using a high-fidelity manikin, in the Clinical Skills Centre, Queen's University Belfast. Cohort A received verbal feedback only on their performance and cohort B received video feedback only. Video analysis using 'StudioCode' software was distributed to students. Each group returned for a second scenario and evaluation 4 weeks later. An assessment tool was created for performance assessment, which included individual skill and global score evaluation.
RESULTS:
One hundred thirty eight final year medical students completed the study. 62 % were female and the mean age was 23.9 years. Students having video feedback had significantly greater improvement in overall scores compared to those receiving verbal feedback (p = 0.006, 95 % CI: 2.8-15.8). Individual skills, including ventilation quality and global score were significantly better with video feedback (p = 0.002 and p < 0.001, respectively) when compared with cohort A. There was a positive change in overall score for cohort B from session one to session two (p < 0.001, 95 % CI: 6.3-15.8) indicating video feedback significantly benefited skill retention. In addition, using video feedback showed a significant improvement in the global score (p < 0.001, 95 % CI: 3.3-7.2) and drug administration timing (p = 0.004, 95 % CI: 0.7-3.8) of cohort B participants, from session one to session two.
CONCLUSIONS:
There is increased use of simulation in medicine but a paucity of published data comparing feedback methods in cardiopulmonary resuscitation training. Our study shows the use of video feedback when teaching cardiopulmonary resuscitation is more effective than verbal feedback, and enhances skill retention. This is one of the first studies to demonstrate the benefit of video feedback in cardiopulmonary resuscitation teaching.

Abstract
BACKGROUND:
Internet and software-based platforms (e-learning) have gained popularity as teaching tools in medical education. Despite widespread use, there is limited evidence to support their effectiveness for surgical training. This study sought to evaluate the effectiveness of e-learning as a teaching tool compared with no intervention and other methods of surgical training.
METHODS:
A systematic literature search of bibliographical databases was performed up to August 2015. Studies were included if they were RCTs assessing the effectiveness of an e-learning platform for teaching any surgical skill, compared with no intervention or another method of training.
RESULTS:
From 4704 studies screened, 87 were included with 7871 participants enrolled, comprising medical students (52 studies), trainees (51 studies), qualified surgeons (2 studies) and nurses (6 studies). E-learning tools were used for teaching cognitive (71 studies), psychomotor (36 studies) and non-technical (8 studies) skills. Tool features included multimedia (84 studies), interactive learning (60 studies), feedback (27 studies), assessment (26 studies), virtual patients (22 studies), virtual reality environment (11 studies), spaced education (7 studies), community discussions (2 studies) and gaming (2 studies). Overall, e-learning showed either greater or similar effectiveness compared with both no intervention (29 and 4 studies respectively) and non-e-learning interventions (29 and 22 studies respectively).
CONCLUSION:
Despite significant heterogeneity amongst platforms, e-learning is at least as effective as other methods of training.

Abstract
OBJECTIVE:
(1) To compare temporal bone anatomy comprehension taught to speech therapy students with or without a papercraft model. (2) To explore the effect of papercraft simulation on the understanding of surgical approaches in first-year residents.
METHODS:
(1) One-hundred and ten speech therapy students were divided into three classes. The first class was taught with a lecture only. The students in the second class were given a lecture and a papercraft modeling task without instruction. The third class modeled a papercraft with instruction after the lecture. The students were tested on their understanding of temporal bone anatomy. (2) A questionnaire on the understanding of surgical approaches was completed by 10 residents before and after the papercraft modeling. The papercraft models were cut with scissors to simulate surgical approaches.
RESULTS:
(1) The average scores were 4.4/8 for the first class, 4.3/8 for the second class, and 6.3/8 for the third class. The third class had significantly better results than the other classes (p<0.01, Kruskal-Wallis test). (2) The average scores before and after the papercraft modeling and cutting were 2.6/7 and 4.9/7, respectively. The numerical rating scale score significantly improved (p<0.01, Wilcoxon signed-rank test).
CONCLUSION:
The instruction of the anatomy using a papercraft temporal bone model is effective in the first step of learning temporal bone anatomy and surgical approaches.

Abstract
BACKGROUND:
Life-threatening midgut volvulus usually occurs in infants with malrotation and requires rapid diagnosis and surgical treatment to prevent bowel necrosis and death. However, because of the low frequency of upper gastrointestinal studies performed in infants younger than 1 month, many diagnostic radiology residents finish their residency training having limited or no opportunity to perform or observe an upper gastrointestinal (GI) series for evaluation of bilious emesis in a neonate.
OBJECTIVE:
To determine whether adding simulated upper GI series on neonates with bilious emesis to the curriculum improves residents' skill and accuracy in diagnosing midgut volvulus.
MATERIALS AND METHODS:
We assessed the performance of 12 residents in training whose curriculum included simulated upper GI series (study group) and 10 traditionally trained residents (control group) using a multiple-choice test, checklist procedure evaluation and diagnostic accuracy scores for 3 randomly selected simulated upper GI series. We then compared the results from the study group that had simulation curriculum to the scores for the control group using the Mann-Whitney test. We also analyzed the scores for the study group obtained prior to and after simulation curriculum using Wilcoxon signed rank test.
RESULTS:
There was a significant difference in test scores (study group median = 84.5%, control group median = 67.2%, P=0.001), overall diagnostic accuracy (study group median = 100%, control group median = 50%, P=0.011) and checklist evaluation (study group median = 83.3%, control group median = 70.8%, P=0.025) for the residents in the study group who completed simulation curriculum compared with the control group. There was also a significant difference in multiple-choice test scores for the study group before and after completion of simulation curriculum (before simulation curriculum median = 56.9%, after simulation curriculum median = 84.5%, P=0.002), checklist evaluation (before simulation curriculum median = 58.3%, after simulation curriculum median = 83.3%, P=0.002) and overall diagnostic accuracy scores (before simulation curriculum median = 50%, after simulation curriculum median = 100%, P=0.024).
CONCLUSION:
Radiology residents had significantly higher scores on a multiple-choice test, checklist procedure evaluation and overall diagnostic accuracy after completing a structured pediatric fluoroscopy curriculum that included simulated neonatal upper GI series and when compared to a control group of traditionally trained residents.

Abstract
BACKGROUND/AIMS:
We developed a new endoscopic biopsy training simulator and determined its efficacy for improving the endoscopic biopsy skills of beginners.
METHODS:
This biopsy simulator, which presents seven biopsy sites, was constructed using readily available materials. We enrolled 40 participants: 14 residents, 11 first-year clinical fellows, 10 second-year clinical fellows, and five staff members. We recorded the simulation completion time for all participants, and then simulator performance was assessed via a questionnaire using the 7-point Likert scale.
RESULTS:
The mean times for completing the five trials were 417.7±138.8, 145.2±31.5, 112.7±21.9, and 90.5±20.0 seconds for the residents, first-year clinical fellows, second-year clinical fellows, and staff members, respectively. Endoscopists with less experience reported that they found this simulator more useful for improving their biopsy technique (6.8±0.4 in the resident group and 5.7±1.0 in the first-year clinical fellow group). The realism score of the simulator for endoscopic handling was 6.4±0.5 in the staff group.
CONCLUSIONS:
This new, easy-to-manufacture endoscopic biopsy simulator is useful for biopsy training for beginner endoscopists and shows good efficacy and realism.

Abstract
CONTEXT:
The handover represents a high-risk event in which errors are common and lead to patient harm. A better understanding of the cognitive mechanisms of handover errors is essential to improving handover education and practice.
OBJECTIVES:
This paper reports on an experiment conducted to study the effects of learner knowledge, case complexity (i.e. cases with or without a clear diagnosis) and their interaction on handover accuracy and cognitive load.
METHODS:
Participants were 52 Dutch medical students in Years 2 and 6. The experiment employed a repeated-measures design with two explanatory variables: case complexity (simple or complex) as the within-subject variable, and learner knowledge (as indicated by illness script maturity) as the between-subject covariate. The dependent variables were handover accuracy and cognitive load. Each participant performed a total of four simulated handovers involving two simple cases and two complex cases.
RESULTS:
Higher illness script maturity predicted increased handover accuracy (p < 0.001) and lower cognitive load (p = 0.007). Case complexity did not independently affect either outcome. For handover accuracy, there was no interaction between case complexity and illness script maturity. For cognitive load, there was an interaction effect between illness script maturity and case complexity, indicating that more mature illness scripts reduced cognitive load less in complex cases than in simple cases.
CONCLUSIONS:
Students with more mature illness scripts performed more accurate handovers and experienced lower cognitive load. For cognitive load, these effects were more pronounced in simple than complex cases. If replicated, these findings suggest that handover curricula and protocols should provide support that varies according to the knowledge of the trainee.

Abstract
CONTEXT:
Fidelity is widely viewed as an important element of simulation instructional design based on its purported relationship with transfer of learning. However, higher levels of fidelity may increase task complexity to a point at which novices' cognitive resources become overloaded.
OBJECTIVES:
In this experiment, we investigate the effects of variations in task complexity on novices' cognitive load and learning during simulation-based procedural skills training.
METHODS:
Thirty-eight medical students were randomly assigned to simulation training on a simple or complex lumbar puncture (LP) task. Participants completed four practice trials on this task (skill acquisition). After 10 days of rest, all participants completed one additional trial on their assigned task (retention) and one trial on a 'very complex' simulation designed to be similar to the complex task (transfer). We assessed LP performance and cognitive load on each trial using multiple measures.
RESULTS:
In both groups, LP performance improved significantly during skill acquisition (p ≤ 0.047, f = 0.29-0.96) and was maintained at retention. The simple task group demonstrated superior performance compared with the complex task group throughout these phases (p ≤ 0.002, d = 1.13-2.31). Cognitive load declined significantly in the simple task group (p < 0.009, f = 0.48-0.76), but not in the complex task group during skill acquisition, and remained lower at retention (p ≤ 0.024, d = 0.78-1.39). Between retention and transfer, LP performance declined and cognitive load increased in the simple task group, whereas both remained stable in the complex task group. At transfer, no group differences were observed in LP performance and cognitive load, except that the simple task group made significantly fewer breaches of sterility (p = 0.023, d = 0.80).
CONCLUSIONS:
Reduced task complexity was associated with superior LP performance and lower cognitive load during skill acquisition and retention, but mixed results on transfer to a more complex task. These results indicate that task complexity is an important factor that may mediate (via cognitive overload) the relationship between instructional design elements (e.g. fidelity) and simulation-based learning outcomes.

Abstract
BACKGROUND:
The purpose of this study was to identify factors that predict medical student success in acquiring invasive procedural skills. We hypothesized that students with interest in surgery and with prior procedural experience would have higher rates of success.
METHODS:
Preclinical students were enrolled in a simulation course comprised of suturing, intubation, and central venous catheterization. Students completed surveys to describe demographics, specialty interest area, prior experience, and confidence. Using linear regression, variables predictive of proficiency were identified.
RESULTS:
Forty-five participants completed the course. Under univariate analysis, composite pretest score was inversely associated with confidence (P = .039). Under multivariable analysis, female gender was associated with higher pretest suturing score (P = .016). Male gender (P = .029) and high confidence (P = .021) were associated with greater improvement in suturing.
CONCLUSIONS:
Among novices, higher confidence can predict lower baseline technical proficiency. Although females had higher pretest suturing scores, high confidence and male gender were associated with the greatest degree of improvement.

Abstract
OBJECTIVE:
Inserting peripheral venous catheters (PVCs) has been identified as a core competency for medical students. Because the performance - even of hygienic standards - of both students and novice physicians is frequently inadequate, medical faculties must focus on competence-based learning objectives and deliberate practice, features that are combined in mastery learning. Our aim was to determine the competency of students in inserting PVCs before and after an educational intervention.
DESIGN:
This study comprised a skills assessment with pre- and post-tests of a group of third-year students who received a simulation-based intervention. A newly established curriculum involved one hour of practice at inserting PVCs on simulators. Students were required to pass a test (total 21 points, pass mark 20 points) developed on the concept of mastery learning. An unannounced follow-up test was performed one week (8 days) after the intervention.
SETTING:
The simulation center of the medical faculty in Muenster.
PARTICIPANTS:
Third-year students who received the intervention.
RESULTS:
One hundred and nine complete data sets were obtained from 133 students (82.5%). Most students (97.2%) passed the test after the intervention (mean score increase from 15.56 to 20.50, P<0.001). There was a significant decrease in students' performance after one week (8 days): only 74.5% of participants passed this retest (mean score reduction from 20.50 to 20.06, P<0.001).
CONCLUSION:
Mastery learning is an effective form of teaching practical skills to medical students, allowing a thorough preparation for the challenges of daily clinical practice.

Abstract
BACKGROUND:
Laparoscopic surgery is a reality in almost all surgical centers. Although with initial greater technical difficulty for surgeons, the rapid return to activities, less postoperative pain and higher quality aesthetic stimulates surgeons to evolve technically in this area. However, unlike open surgery where learning opportunities are more accessible, the laparoscopic training represents a challenge in surgeon formation.
AIM:
To present a low cost model for laparoscopic training box.
METHODS:
This model is based in easily accessible materials; the equipment can be easily found based on chrome mini jet and passes rubber thread and a webcam attached to an aluminum handle.
RESULTS:
It can be finalized in two days costing R$ 280,00 (US$ 90).
CONCLUSION:
It is possible to stimulate a larger number of surgeons to have self training in laparoscopy at low cost seeking to improve their surgical skills outside the operating room

Abstract
BACKGROUND:
Live tissue models are considered the most useful simulation for training in the management for hemostasis of penetrating injuries. However, these models are expensive, with limited opportunities for repetitive training. Ex-vivo models using tissue and a fluid pump are less expensive, allow repetitive training and respect ethical principles in animal research. The purpose of this study is to objectively evaluate the effectiveness of ex-vivo training with a pump, compared to live animal model training. Staff surgeons and residents were divided into live tissue training and ex-vivo training groups. Training in the management of a penetrating cardiac injury was conducted for each group, separately. One week later, all participants were formally evaluated in the management of a penetrating cardiac injury in a live animal.
RESULTS:
There are no differences between the two groups regarding average years of experience or previous trauma surgery experience. All participants achieved hemostasis, with no difference between the two groups in the Global Rating Scale score (ex-vivo: 25.2 ± 6.3, live: 24.7 ± 6.3, p = 0.646), blood loss (1.6 ± 0.7, 2.0 ± 0.6, p = 0.051), checklist score (3.7 ± 0.6, 3.6 ± 0.9, p = 0.189), or time required for repair (101 s ± 31, 107 s ± 15, p = 0.163), except overall evaluation (3.8 ± 0.9, 3.4 ± 0.9, p = 0.037). The internal consistency reliability and inter-rater reliability in the Global Rating Scale were excellent (0.966 and 0.953 / 0.719 and 0.784, respectively), and for the checklist were moderate (0.570 and 0.636 / 0.651 and 0.607, respectively). The validity is rated good for both the Global Rating Scale (Residents: 21.7 ± 5.6, Staff: 28.9 ± 4.7, p = 0.000) and checklist (Residents: 3.4 ± 0.9, Staff Surgeons: 3.9 ± 0.3, p = 0.003). The results of self-assessment questionnaires were similarly high (4.2-4.9) with scores in self-efficacy increased after training (pre: 1.7 ± 0.8, post: 3.2 ± 1.0, p = 0.000 in ex-vivo, pre: 1.9 ± 1.0, post: 3.7 ± 0.7, p = 0.000 in live). Scores comparing pre-training and post-evaluation (pre: 1.7 ± 0.8, post: 3.7 ± 0.9, p = 0.000 in ex-vivo, pre: 1.9 ± 1.0, post: 3.8 ± 0.7, p = 0.000 in live) were increased.
CONCLUSION:
Training with an ex-vivo model and live tissue training are similar for the management of a penetrating cardiac injury, with increased self-efficacy of participants in both groups. The ex-vivo model is useful to learn hemostatic skills in trauma surgery.

Abstract
INTRODUCTION:
Traditional Advanced Cardiac Life Support (ACLS) courses are evaluated using written multiple-choice tests. High-fidelity simulation is a widely used adjunct to didactic content, and has been used in many specialties as a training resource as well as an evaluative tool. There are no data to our knowledge that compare simulation examination scores with written test scores for ACLS courses.
OBJECTIVE:
To compare and correlate a novel high-fidelity simulation-based evaluation with traditional written testing for senior medical students in an ACLS course.
METHODS:
We performed a prospective cohort study to determine the correlation between simulation-based evaluation and traditional written testing in a medical school simulation center. Students were tested on a standard acute coronary syndrome/ventricular fibrillation cardiac arrest scenario. Our primary outcome measure was correlation of exam results for 19 volunteer fourth-year medical students after a 32-hour ACLS-based Resuscitation Boot Camp course. Our secondary outcome was comparison of simulation-based vs. written outcome scores.
RESULTS:
The composite average score on the written evaluation was substantially higher (93.6%) than the simulation performance score (81.3%, absolute difference 12.3%, 95% CI [10.6-14.0%], p<0.00005). We found a statistically significant moderate correlation between simulation scenario test performance and traditional written testing (Pearson r=0.48, p=0.04), validating the new evaluation method.
CONCLUSION:
Simulation-based ACLS evaluation methods correlate with traditional written testing and demonstrate resuscitation knowledge and skills. Simulation may be a more discriminating and challenging testing method, as students scored higher on written evaluation methods compared to simulation.

Abstract
BACKGROUND:
There are international concerns in relation to the management of patient deterioration which has led to a body of evidence known as the 'failure to rescue' literature. Nursing staff are known to miss cues of deterioration and often fail to call for assistance. Medical Emergency Teams (Rapid Response Teams) do improve the management of acutely deteriorating patients, but first responders need the requisite skills to impact on patient safety.
METHODS/DESIGN:
In this study we aim to address these issues in a mixed methods interventional trial with the objective of measuring and comparing the cost and clinical impact of face-to-face and web-based simulation programs on the management of patient deterioration and related patient outcomes. The education programs, known as 'FIRST(2)ACT', have been found to have an impact on education and will be tested in four hospitals in the State of Victoria, Australia. Nursing staff will be trained in primary (the first 8 min) responses to emergencies in two medical wards using a face-to-face approach and in two medical wards using a web-based version FIRST(2)ACTWeb. The impact of these interventions will be determined through quantitative and qualitative approaches, cost analyses and patient notes review (time series analyses) to measure quality of care and patient outcomes.
DISCUSSION:
In this 18 month study it is hypothesised that both simulation programs will improve the detection and management of deteriorating patients but that the web-based program will have lower total costs. The study will also add to our overall understanding of the utility of simulation approaches in the preparation of nurses working in hospital wards.

Abstract
OBJECTIVE:
The purpose of this study was to determine whether simulation-based training can improve resident performance in ultrasound-guided biopsy.
SUBJECTS AND METHODS:
Forty radiology residents from a single academic institution enrolled in the study. Each resident performed an initial biopsy on an abdominal imaging phantom using direct ultrasound guidance. Twenty of the residents underwent a 30-minute training session with the phantom device, and 20 residents received no additional training. The residents performed a repeat biopsy of the same lesion and were graded on overall procedure time, number of skin surface punctures, number of gross needle adjustments, and subjective performance as determined by a blinded grader.
RESULTS:
Residents who participated in the training had a statistically significant 92.3-second reduction in procedure time (68% improvement, p = 0.01), 1.1 reduction in number of skin punctures per biopsy (50% improvement, p = 0.05), 2.5 reduction in number of needle adjustments (66% improvement, p = 0.04), and an increase of 0.85 points in score on a 5-point Likert grading scale (23% improvement, p < 0.01). Residents who did not receive any additional training did not improve in any performance metric.
CONCLUSION:
Simulation-based training improves overall procedure time, number of skin punctures and needle adjustments, and subjective performance.

Abstract
INTRODUCTION:
Neurosurgery simulation has gained attention recently due to changes in the medical system. First-year neurosurgical residents in low-income countries usually perform their first craniotomy on a real subject. Development of high-fidelity, cheap, and largely available simulators is a challenge in residency training. An original model for the first steps of craniotomy with cerebrospinal fluid (CSF) leak avoidance practice using a coconut is described.
MATERIAL AND METHODS:
The coconut is a drupe from Cocos nucifera L. (coconut tree). The green coconut has four layers and some similarity can be seen between these layers and the human skull. The materials used in the simulation are the same as those used in the operating room.
PROCEDURE:
The coconut is placed on the head holder support with the face up. The burr holes are made until endocarp is reached. The mesocarp is dissected, and the conductor is passed from one hole to the other with the Gigli saw. The hook handle for the wire saw is positioned, and the mesocarp and endocarp are cut. After sawing the four margins, mesocarp is detached from endocarp. Four burr holes are made from endocarp to endosperm. Careful dissection of the endosperm is done, avoiding liquid albumen leak. The Gigli saw is passed through the trephine holes. Hooks are placed, and the endocarp is cut. After cutting the four margins, it is dissected from the endosperm and removed. The main goal of the procedure is to remove the endocarp without fluid leakage.
DISCUSSION:
The coconut model for learning the first steps of craniotomy and CSF leak avoidance has some limitations. It is more realistic while trying to remove the endocarp without damage to the endosperm. It is also cheap and can be widely used in low-income countries. However, the coconut does not have anatomical landmarks. The mesocarp makes the model less realistic because it has fibers that make the procedure more difficult and different from a real craniotomy.
CONCLUSION:
The model has a potential pedagogic neurosurgical application for freshman residents before they perform a real craniotomy for the first time. Further validity is necessary to confirm this hypothesis.

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.
