Is It the Athlete Or the Equipment? An analysis of the top swim performances from 1990-2010.
J Strength Cond Res. 2011 Sep 29. [Epub ahead of print]
PMID: 21964430
Abstract
Forty-three world record swims were recorded at the 2009 Fédération Internationale de Natation (FINA) World Championship meet in Rome. Of the 20 FINA recognized long-course (50m pool) swimming events, men set new world records in 15 of those events while women did the same in 17 events. Each of the men's world records and 14 of the 17 women's records still stand. These performances were unprecedented; never before had this many world records been broken in such a short period of time. There was much speculation that full-body, polyurethane, technical swimsuits were the reason for the conspicuous improvement in world records. Further analysis led FINA to institute new rules on January 1, 2010, that limited the types of technical swimsuits that could be worn by athletes. No long-course world record has been broken since then. We sought to understand this phenomenon by analyzing publically available race data and exploring other possible causes including: improvements in other sports; improvements in training science; changes in rules and regulations; gender differences; anaerobic vs. aerobic events; unique talent; and membership data.- PMID:

Simulation-based team training in healthcare.
Simul Healthc. 2011 Aug;6 Suppl:S14-9
Authors: Eppich W, Howard V, Vozenilek J, Curran I
: Simulation-based team training (SBTT) in healthcare is gaining acceptance. Guidelines for appropriate use of SBTT exist, but the evidence base remains limited. Insights from other academic disciplines with sophisticated models of team working may point to opportunities to build on current frameworks applied to team training in healthcare. The purpose of this consensus statement is threefold: (1) to highlight current best practices in designing SBTT in healthcare and to identify gaps in current implementation; (2) to explore validated concepts and principles from relevant academic disciplines and industries; and (3) to identify potential high-yield areas for future research and development.

Abstract
INTRODUCTION:
A long and rich research legacy shows that under the right conditions, simulation-based medical education (SBME) is a powerful intervention to increase medical learner competence. SBME translational science demonstrates that results achieved in the educational laboratory (T1) transfer to improved downstream patient care practices (T2) and improved patient and public health (T3).
METHOD:
This is a qualitative synthesis of SBME translational science research (TSR) that employs a critical review approach to literature aggregation.
RESULTS:
Evidence from SBME and health services research programs that are thematic, sustained, and cumulative shows that measured outcomes can be achieved at T1, T2, and T3 levels. There is also evidence that SBME TSR can yield a favorable return on financial investment and contributes to long-term retention of acquired clinical skills. The review identifies best practices in SBME TSR, presents challenges and critical gaps in the field, and sets forth a TSR agenda for SBME.
CONCLUSIONS:
Rigorous SBME TSR can contribute to better patient care and improved patient safety. Consensus conference outcomes and recommendations should be presented and used judiciously.

Pugh, Carla M. MD, PhD; Bevan, Matthew G. PhD; Duve, Rebecca J. MS; White, Heather L. BA; Magee, J. Harvey BA; Wiehagen, Gene B. BS
Pub med ID 21546864
Introduction: In February 2000, the U.S. Army's Telemedicine and Advanced Technology Research Center (TATRC) and the U.S. Army's Simulation, Training, and Instrumentation Command cohosted an Integrated Research Team conference in Maryland. The goal of the conference was to enable end users, researchers, materiel developers, and other government agencies to present their conceptions of how modeling and simulation could and should be developed to meet military medical needs. During the past 9 years, TATRC has funded more than 175 projects relating to simulation.
Methods: This study was a retrospective review of TATRC's Modeling and Simulation Training projects (N = 175).Results: Our results show that most (>75%) of the funded projects in this study involved industry. More than 85% of the projects that involved industry focused on technology development. Industry development projects seemed to meet their deliverables in a timely fashion. However, academia projects using industry-developed technologies and prototypes were delayed largely because the technologies did not meet their needs.
Discussion: There seems to be a measurable gap between industry's definition of a completed product technology and academia's ability to implement and use the technology in interactive learning environments. Our findings support the need for a standardized strategic design process that involves a strong industry-academia collaboration and early end-user testing to better facilitate the development of sound requirements that guide technology development.

Emergency Medicine
ABSTRACT: Objectives: Oral examination is a method used to
evaluate emergency medicine (EM) residents and is a requirement for board
certification of emergency physicians. Second Life (SL) is a virtual
three-dimensional (3-D) immersive learning environment that has been used for
medical education. In this study we explore the use of SL virtual simulation
technology to administer mock oral examinations to EM residents.
Methods: This was a prospective observational study of EM residents who had previously
completed mock oral examinations, participating in a similar mock oral
examination case scenario conducted via SL. EM residents in this training program
completed mock oral examinations in a traditional format, conducted face to face
with a faculty examiner. All current residents were invited to participate in a
similar case scenario conducted via SL for this study. The examinee managed the
case while acting as the physician avatar and communicated via headset and
microphone from a remote computer with a faculty examiner who acted as the
patient avatar. Participants were surveyed regarding their experience with the
traditional and virtual formats using a Likert scale.
Results: Twenty-seven EM
residents participated in the virtual oral examination. None of the examinees had
used SL previously. SL proved easy for examinees to log into (92.6%) and navigate
(96.3%). All felt comfortable communicating with the examiner via remote
computer. Most examinees thought the SL encounter was realistic (92.6%), and many
found it more realistic than the traditional format (70.3%). All examinees felt
that the virtual examination was fair, objective, and conducted efficiently. A
majority preferred to take oral examinations via SL over the traditional format
and expressed interest in using SL for other educational experiences (66.6 and
92.6%, respectively).
Conclusions: Application of SL virtual simulation
technology is a potential alternative to traditional mock oral examinations for
EM residents.

Does Simulation-Based Medical Education With Deliberate Practice Yield Better Results Than Traditional Clinical Education? A Meta-Analytic Comparative
Acad Med. 2011 Apr 20. [Epub ahead of print]
McGaghie WC, Issenberg SB, Cohen ER, Barsuk JH, Wayne DB.
Abstract
PURPOSE: This article presents a comparison of the effectiveness of traditional clinical education toward skill acquisition goals versus simulation-based medical education (SBME) with deliberate practice (DP).
METHOD: This is a quantitative meta-analysis that spans 20 years, 1990 to 2010. A search strategy involving three literature databases, 12 search terms, and four inclusion criteria was used. Four authors independently retrieved and reviewed articles. Main outcome measures were extracted to calculate effect sizes.
RESULTS: Of 3,742 articles identified, 14 met inclusion criteria. The overall effect size for the 14 studies evaluating the comparative effectiveness of SBME compared with traditional clinical medical education was 0.71 (95% confidence interval, 0.65-0.76; P < .001). CONCLUSIONS: Although the number of reports analyzed in this meta-analysis is small, these results show that SBME with DP is superior to traditional clinical medical education in achieving specific clinical skill acquisition goals. SBME is a complex educational intervention that should be introduced thoughtfully and evaluated rigorously at training sites. Further research on incorporating SBME with DP into medical education is needed to amplify its power, utility, and cost-effectiveness.

Abstract
BACKGROUND: Effective collaboration and teamwork is essential to providing safe hospital care. The objective of this study was to assess the effect of an intervention designed to improve interdisciplinary collaboration and lower the rate of adverse events (AEs).
METHODS: The study was a controlled trial of an intervention, Structured Inter-Disciplinary Rounds, implemented in 1 of 2 similar medical teaching units in a tertiary care academic hospital. The intervention combined a structured format for communication with a forum for regular interdisciplinary meetings. We conducted a retrospective medical record review evaluating 370 randomly selected patients admitted to the intervention and control units (n = 185 each) in the 24 weeks after and 185 admitted to the intervention unit in the 24 weeks before the implementation of Structured Inter-Disciplinary Rounds (N = 555). Medical records were screened for AEs. Two hospitalists confirmed the presence of AEs and assessed their preventability and severity in a masked fashion. We used multivariable Poisson regression models to compare the adjusted incidence of AEs in the intervention unit to that in concurrent and historic control units.
RESULTS: The rate of AEs was 3.9 per 100 patient-days for the intervention unit compared with 7.2 and 7.7 per 100 patient-days, respectively, for the concurrent and historic control units (adjusted rate ratio, 0.54; P = .005; and 0.51; P = .001). The rate of preventable AEs was 0.9 per 100 patient-days for the intervention unit compared with 2.8 and 2.1 per 100 patient-days for the concurrent and historic control units (adjusted rate ratio, 0.27; P = .002; and 0.37; P = .02). The low number of AEs rated as serious or life-threatening precluded statistical analysis for differences in rates of events classified as serious or serious and preventable.
CONCLUSION: Structured Inter-Disciplinary Rounds significantly reduced the adjusted rate of AEs in a medical teaching unit.

We have developed a way to measure performance during a camera-guided rigid
bronchoscopy using manikin-based simulation. In an effort to measure contact
pressures within the airway during a rigid bronchoscopy, we instrumented pressure
sensors in a commercially available bronchoscopy task trainer. Participants were
divided into two groups based on self-reported levels of expertise: novice (none
to minimal experience in rigid bronchoscopy) and experts (moderate to extensive
experience). There was no significant difference between experts and novices in
the time taken to complete the rigid bronchoscopy. However, novices touched a
greater number of areas than experts, showing that novices induce a higher number
of unnecessary soft-tissue contact compared to experts. Moreover, our results
show that experts exert significantly less soft tissue pressure compared to
novices.

Abstract
This study introduces a novel way to implement simulation in medical education. We investigated the feasibility of integrating a newly developed breast examination simulator into a breast exam technique lecture while also collecting detailed data on medical students' breast exam skills. Results indicate that it is feasible to integrate simulation technology into the classroom environment and collect detailed performance data that can be analyzed and used for skills assessment.

Comparison of Checklist and Anchored Global Rating Instruments for Performance Rating of Simulated Pediatric Emergencies
Simulation in Healthcare: The Journal of the Society for Simulation in Healthcare:
February 2011 - Volume 6 - Issue 1 - pp 18-24
doi: 10.1097/SIH.0b013e318201aa90
Purpose: To compare the psychometric performance of two rating instruments used to assess trainee performance in three clinical scenarios.
Methods: This study was part of a two-phase, randomized trial with a wait-list control condition assessing the effectiveness of a pediatric emergency medicine curriculum targeting general emergency medicine residents. Residents received 6 hours of instruction either before or after the first assessment. Separate pairs of raters completed either a dichotomous checklist for each of three cases or the Global Performance Assessment Tool (GPAT), an anchored multidimensional scale. A fully crossed person × rater × case generalizability study was conducted. The effect of training year on performance is assessed using multivariate analysis of variance.
Results: The person and person × case components accounted for most of the score variance for both instruments. Using either instrument, scores demonstrated a small but significant increase as training level increased when analyzed using a multivariate analysis of variance. The inter-rater reliability coefficient was >0.9 for both instruments.
Conclusions: We demonstrate that our checklist and anchored global rating instrument performed in a psychometrically similar fashion with high reliability. As long as proper attention is given to instrument design and testing and rater training, checklists and anchored assessment scales can produce reproducible data for a given population of subjects. The validity of the data arising for either instrument type must be assessed rigorously and with a focus, when practicable, on patient care outcomes.

Abstract
Advanced esophageal endoscopic procedures such as stricture dilation, hemostasis tools, and stent placement as well as high-resolution manometry (HRM) interpretation are necessary skills for gastroenterology fellows to obtain during their training. Becoming proficient in these skills may be challenging in light of higher complication rates compared with diagnostic procedures and infrequent opportunities to practice these skills. Our aim was to determine if intensive training during a continuing medical education (CME) course boosts the knowledge and skills of gastroenterology fellows in esophageal diagnostic test interpretation and performance of therapeutic procedures. This was a pretest-posttest design without a control group of a simulation-based, educational intervention in esophageal stricture balloon dilation and HRM interpretation. The participants were 24 gastroenterology fellows from 21 accredited US training programs. This was an intensive CME course held in Las Vegas, Nevada from August 7 to August 9, 2009. The research procedure had two phases. First, the subjects were measured at baseline (pretest) for their knowledge and procedural skill. Second, the fellows received 6 hours of education sessions featuring didactic content, instruction in HRM indications and interpretation, and deliberate practice using an esophageal stricture dilation model. After the intervention, all of the fellows were retested (posttest). A 17-item checklist was developed for the esophageal balloon dilation procedure using relevant sources, expert opinion, and rigorous step-by-step procedures. Nineteen representative HRM swallow studies were obtained from Northwestern's motility lab and formed the pretest and posttest in HRM interpretation. Mean scores on the dilation checklist improved 81% from 39.4% (standard deviation [SD]= 33.4%) at pretest to 71.3% (SD = 29.5%) after simulation training (P < sd =" 16.4%)" sd =" 15.8%),">

A report on the piloting of a novel computer-based medical case simulation for teaching and formative assessment of diagnostic laboratory testing
Department of Pathology, University of Iowa Carver College of Medicine, Iowa City, IA, USA;
Northwestern University Feinberg School of Medicine, Chicago, IL, USA
Citation: Medical Education Online 2011, 16: 5646 - DOI: 10.3402/meo.v16i0.5646
Objectives: Insufficient attention has been given to how information from computer-based clinical case simulations is presented, collected, and scored. Research is needed on how best to design such simulations to acquire valid performance assessment data that can act as useful feedback for educational applications. This report describes a study of a new simulation format with design features aimed at improving both its formative assessment feedback and educational function.
Methods: Case simulation software (LabCAPS) was developed to target a highly focused and well-defined measurement goal with a response format that allowed objective scoring. Data from an eight-case computerbased performance assessment administered in a pilot study to 13 second-year medical students was analyzed using classical test theory and generalizability analysis. In addition, a similar analysis was conducted on an administration in a less controlled setting, but to a much large sample (n 143), within a clinical course that utilized two random case subsets from a library of 18 cases.
Results: Classical test theory case-level item analysis of the pilot assessment yielded an average case discrimination of 0.37, and all eight cases were positively discriminating (range 0.11 0.56). Classical test theory coefficient alpha and the decision study showed the eight-case performance assessment to have an observed reliability of s G 0.70. The decision study further demonstrated that a G 0.80 could be attained with approximately 3 h and 15 min of testing. The less-controlled educational application within a large medical class produced a somewhat lower reliability for eight cases (G 0.53). Students gave high ratings to the logic of the simulation interface, its educational value, and to the fidelity of the tasks.
Conclusions: LabCAPS software shows the potential to provide formative assessment of medical students’ skill at diagnostic test ordering and to provide valid feedback to learners. The perceived fidelity of the performance tasks and the statistical reliability findings support the validity of using the automated scores for formative assessment and learning. LabCAPS cases appear well designed for use as a scored assignment, for stimulating discussions in small group educational settings, for self-assessment, and for independent learning. Extension of the more highly controlled pilot assessment study with a larger sample will be needed to confirm its reliability in other assessment applications.

BACKGROUND: Previous studies using simulation-based curricula have focused largely on technical skills. We developed a set of simulation-based modules that focus on intraoperative decision making. The objective of this study was to conduct a faculty evaluation of: (1) the usefulness of 4 newly developed, simulation-based modules; (2) the curricular need to train and assess intraoperative decision making skills of the residents; and (3) potential for resident benefit.
METHODS: Simulation-based modules were developed using a cognitive task analysis (CTA) framework. The CTA framework involved faculty interviews focusing on 4 operative tasks that span a range of complexity: (1) creation of small and large bowel stoma, (2) laparoscopic ventral hernia repair, (3) pancreaticojejunostomy, and (4) lymph node biopsy during a mediastinoscopy. An experienced psychologist conducted task-specific, one-on-one interviews with fellowship-trained specialists who perform these operations in their practice. Two faculty were interviewed for each procedure. The interviews lasted a minimum of 1 hour and focused on critical decisions, error prevention, error recognition, and error rescue strategies. The coded interview summaries were used as development guides for the simulation-based learning modules. Each module included locally developed physical models for the simulated operative tasks combined with oral and paper-based questions. The physical models were fabricated in such a way that simulated operative tasks could be performed using standard surgical instruments. To assess the newly developed simulation-based modules, 8 volunteer faculty (50% overlap with the interview pool) participated in a simulation-based exercise during a one-on-one session and then completed an 8-item survey cast on a 5-point Likert agreement scale (1 = strongly disagree, 5 = strongly agree). One of the items was worded negatively to ensure internal consistency. An independent observer recorded faculty session times and assessed faculty engagement in the task (1 = not engaged, 5 = extremely engaged).
RESULTS: On average, faculty spent 60 minutes completing each simulation-based exercise. Over 80% of this time was spent performing the operative tasks as they would during a real-life procedure. Mean engagement rating was 4.9 (maximum 5.0, SD = 0.3). Survey results show strong agreement on the importance of training and assessing intraoperative decision making, and that residents would likely benefit from the simulation-based modules.
CONCLUSION: We developed 4 high-fidelity simulation-based modules to assess intraoperative decision making. Faculty agree strongly on the importance and need for additional modules.
