Sample records for human simulation training

  1. Flight Simulator and Training Human Factors Validation (United States)

    Glaser, Scott T.; Leland, Richard


    Loss of control has been identified as the leading cause of aircraft accidents in recent years. Efforts have been made to better equip pilots to deal with these types of events, commonly referred to as upsets. A major challenge in these endeavors has been recreating the motion environments found in flight as the majority of upsets take place well beyond the normal operating envelope of large aircraft. The Environmental Tectonics Corporation has developed a simulator motion base, called GYROLAB, that is capable of recreating the sustained accelerations, or G-forces, and motions of flight. A two part research study was accomplished that coupled NASA's Generic Transport Model with a GYROLAB device. The goal of the study was to characterize physiological effects of the upset environment and to demonstrate that a sustained motion based simulator can be an effective means for upset recovery training. Two groups of 25 Air Transport Pilots participated in the study. The results showed reliable signs of pilot arousal at specific stages of similar upsets. Further validation also demonstrated that sustained motion technology was successful in improving pilot performance during recovery following an extensive training program using GYROLAB technology.

    Sandia National Laboratories has developed a distributed, high fidelity simulation system for training and planning small team Operations. The system provides an immersive environment populated by virtual objects and humans capable of displaying complex behaviors. The work has focused on developing the behaviors required to carry out complex tasks and decision making under stress. Central to this work are techniques for creating behaviors for virtual humans and for dynamically assigning behaviors to CGF to allow scenarios without fixed outcomes. Two prototype systems have been developed that illustrate these capabilities: MediSim, a trainer for battlefield medics and VRaptor, a system for planning, rehearsing and training assault operations.

  5. Hand-assisted laparoscopic sigmoid colectomy skills acquisition: augmented reality simulator versus human cadaver training models. (United States)

    Leblanc, Fabien; Senagore, Anthony J; Ellis, Clyde N; Champagne, Bradley J; Augestad, Knut M; Neary, Paul C; Delaney, Conor P


    The aim of this study was to compare a simulator with the human cadaver model for hand-assisted laparoscopic colorectal skills acquisition training. An observational prospective comparative study was conducted to compare the laparoscopic surgery training models. The study took place during the laparoscopic colectomy training course performed at the annual scientific meeting of the American Society of Colon and Rectal Surgeons. Thirty four practicing surgeons performed hand-assisted laparoscopic sigmoid colectomy on human cadavers (n = 7) and on an augmented reality simulator (n = 27). Prior laparoscopic colorectal experience was assessed. Trainers and trainees completed independently objective structured assessment forms. Training models were compared by trainees' technical skills scores, events scores, and satisfaction. Prior laparoscopic experience was similar in both surgeon groups. Generic and specific skills scores were similar on both training models. Generic events scores were significantly better on the cadaver model. The 2 most frequent generic events occurring on the simulator were poor hand-eye coordination and inefficient use of retraction. Specific events were scored better on the simulator and reached the significance limit (p = 0.051) for trainers. The specific events occurring on the cadaver were intestinal perforation and left ureter identification difficulties. Overall satisfaction was better for the cadaver than for the simulator model (p = 0.009). With regard to skills scores, the augmented reality simulator had adequate qualities for the hand-assisted laparoscopic colectomy training. Nevertheless, events scores highlighted weaknesses of the anatomical replication on the simulator. Although improvements likely will be required to incorporate the simulator more routinely into the colorectal training, it may be useful in its current form for more junior trainees or those early on their learning curve.

  6. Does training with human patient simulation translate to improved patient safety and outcome? (United States)

    Shear, Torin D; Greenberg, Steven B; Tokarczyk, Arthur


    In this review, we evaluate several articles in an attempt to qualify the effect of human patient simulation in anaesthesia on patient outcome. The recognition of medical error as a significant cause of patient morbidity and mortality has sparked an increased focus on improving healthcare quality and patient safety. Simulation in anaesthesia is a potential tool to help achieve this goal by allowing anaesthesia providers to learn, practice and perfect their craft without a potential harm to patients. It has gained growing traction in the field and is recently a required element in the American Board of Anesthesiology's Maintenance of Certification in Anesthesia programme. Very few studies have evaluated the effect of simulation on patient outcome. To date, one study has demonstrated improved individual clinical performance in anaesthesia after simulation training. Research suggests that simulation-based team training can reduce patient mortality and improve the quality of care as measured by surgical quality improvement measures. Simulation may improve healthcare systems by serving as a tool to detect latent error and drive process improvement. Despite the adoption of simulation, further study is needed to better qualify its effect on patient safety and outcome.

  7. A comparison of human cadaver and augmented reality simulator models for straight laparoscopic colorectal skills acquisition training. (United States)

    LeBlanc, Fabien; Champagne, Bradley J; Augestad, Knut M; Neary, Paul C; Senagore, Anthony J; Ellis, Clyde N; Delaney, Conor P


    The aim of this study was to compare the human cadaver model with an augmented reality simulator for straight laparoscopic colorectal skills acquisition. Thirty-five sigmoid colectomies were performed on a cadaver (n = 7) or an augmented reality simulator (n = 28) during a laparoscopic training course. Prior laparoscopic colorectal experience was assessed. Objective structured technical skills assessment forms were completed by trainers and trainees independently. Groups were compared according to technical skills and events scores and satisfaction with training model. Prior laparoscopic experience was similar in both groups. For trainers and trainees, technical skills scores were considerably better on the simulator than on the cadaver. For trainers, generic events score was also considerably better on the simulator than on the cadaver. The main generic event occurring on both models was errors in the use of retraction. The main specific event occurring on both models was bowel perforation. Global satisfaction was better for the cadaver than for the simulator model (p < 0.001). The human cadaver model was more difficult but better appreciated than the simulator for laparoscopic sigmoid colectomy training. Simulator training followed by cadaver training can appropriately integrate simulators into the learning curve and maintain the benefits of both training methodologies. Published by Elsevier Inc.

Secondly, cognitive agents can enhance

  9. Who's Driving? The role and training of the human patient simulation operator. (United States)

    Gantt, Laura


    Within the airline industry, where much of simulation-based education originated, cockpit simulators are operated by current or former pilots whose expertise ensures the authenticity of the training experience. As yet, identifying the most appropriate person to run a patient simulator has not been translated into healthcare. Furthermore, few training resources exist for those who must learn the intricacies of the relationship between patient simulators, simulation scenarios, and educational objectives. This article reviews literature related to the role, educational preparation, and training of the patient simulator operator and explores solutions to the uncertainty about the difference between simulator operators and technicians. Because simulators are operationally intensive and because scarce faculty may be best used to facilitate student learning within the laboratory, the tendency has been to use a variety of personnel to manage patient simulators. Recommendations for standardizing the role of the operator that are consistent with the pedagogical purposes of simulation are offered. Potential questions are posed, and methods for future work are discussed.

  10. Feasibility of Human Factors Immersive Simulation Training in Ophthalmology: The London Pilot. (United States)

    Saleh, George M; Wawrzynski, James R; Saha, Kamran; Smith, Phillip; Flanagan, Declan; Hingorani, Melanie; John, Clinton; Sullivan, Paul


    Human factors training can enhance teamworking and reduce error. It is used regularly in certain medical disciplines, but its use has not been established for ophthalmology to our knowledge. To explore the feasibility of providing immersive simulation human factors training for ophthalmic surgical teams. Prospective scenario-based simulation and concept description at University College London Hospital and Moorfields Eye Hospital, London, England, from December 12, 2013, to March 13, 2014. At both sites, fully immersive simulated operating theater environments were used, comprising live interactive communication with patients and theater staff, full anesthetic and operating facilities, replicated patient notes, active vital signs, and the ability to contact surgical or anesthetic teams outside of the theater via telephone. Participants were consultant (attending) and trainee ophthalmic surgeons and anesthetists, operating department assistants and practitioners, and ophthalmic nursing staff. The following 4 previously validated rating tools for nontechnical skills were applied to a replicated series of scenarios based on actual patient safety incidents at Moorfields Eye Hospital and in the literature: Observational Teamwork Assessment for Surgery (OTAS), Non-Technical Skills Scale (NOTECHS), Anesthetists' Non-Technical Skills (ANTS), and Non-Technical Skills for Surgeons (NOTSS). The Pearson product moment correlation coefficient was calculated for each pair of scoring tools. Intertool and interassessor reliability was established. Interassessor consistency was compared by calculating a normalized standard deviation of scores for each tool across all assessors. Twenty simulation scenarios, including wrong intraocular lens implantation, wrong eye operation, wrong drug administration, and wrong patient, were provided. The intertool correlations were 0.732 (95% CI, 0.271-0.919; P = .01) for NOTECHS vs ANTS, 0.922 (95% CI, 0.814-0.968; P < .001) for NOTSS vs

    The analysis of operating experience in nuclear Sta Maria de Garona point to fundamental human factor. After evaluation of the Peer Review, reinforcing behavior expectations was identified as improvement area. The human behavior simulator aims at minimizing human error. Making teamwork practices ensures that the equipment itself reinforces their behavior and performance in the work of the Central. The scope of practice to perform on the simulator includes all phases of execution. The team should analyze the best way to run, the impact of it on the ground and interaction with other sections, being the simulator training environment the situation closer to reality.

  12. Simulation and surgical training. (United States)

    Sarker, S K; Patel, B


    The aim of this review was to outline current forms of surgical simulation and methods of assessing technical skills using these forms of simulation. To review this subject, a literature search was done using key words 'assessment', 'simulation', 'surgery', 'technical skills' and 'virtual reality'. Simulation in surgery has several forms, inorganic (synthetic & computer) and organic (animal or cadaver). Surgical simulation is a mode of training which is promising and may be effective. Technical errors in the simulated environment do not have clinical consequences and does not have a morbidity or mortality. We must ensure that the competent skills learnt in the simulation environment are translated to the real environment. This can be achieved if the same assessment tools are used in both environments. Surgical training is entering a new era, with increased scrutiny and an evolving work and training environment. We as surgical teachers must ensure that the surgeons of the future are as competent as or better than their predecessors using these new modes of training which we have access to.

  13. Training by simulation

    Energy Technology Data Exchange (ETDEWEB)

    Angelini, E.


    Effective training by simulation is a matter of 1. accurate definition of the training need, 2. selecting the right hardware/software package to do the job cost effectively, 3. careful, methodical building of the training program and 4. an appropriate setting, such as a well-equipped training center. Several points seem clear: 1. ''Computer shock'' or computer phobia -- that is, fear of the simulator, can be a factor with some of the older operators. But it quickly disappears once they're into the program, and learn the versatility and the exciting dynamics of simulators. 2. Operator training is becoming more sophisticated throughout the HPI. Among other things, operators should get out into the plant to learn more about how their actions in the control room impact the plant. Operators are becoming more ''big picture'' oriented. 3. When inexperienced training instructors are used, they should attend a good ''train the trainer'' course emphasizing platform skills and instructional technology. 4. Operators need as much ''hands on'' experience with the plant's actual operating equipment as possible. The cognitive ''linkage'' between that equipment and what they see on the CRT is vitally important.

  17. Human Factors in Training (United States)

    Barshi, Immanuel; Byrne, Vicky; Arsintescu, Lucia; Connell, Erin


    Future space missions will be significantly longer than current shuttle missions and new systems will be more complex than current systems. Increasing communication delays between crews and Earth-based support means that astronauts need to be prepared to handle the unexpected on their own. As crews become more autonomous, their potential span of control and required expertise must grow to match their autonomy. It is not possible to train for every eventuality ahead of time on the ground, or to maintain trained skills across long intervals of disuse. To adequately prepare NASA personnel for these challenges, new training approaches, methodologies, and tools are required. This research project aims at developing these training capabilities. By researching established training principles, examining future needs, and by using current practices in space flight training as test beds, both in Flight Controller and Crew Medical domains, this research project is mitigating program risks and generating templates and requirements to meet future training needs. Training efforts in Fiscal Year 09 (FY09) strongly focused on crew medical training, but also began exploring how Space Flight Resource Management training for Mission Operations Directorate (MOD) Flight Controllers could be integrated with systems training for optimal Mission Control Center (MCC) operations. The Training Task addresses Program risks that lie at the intersection of the following three risks identified by the Project: 1) Risk associated with poor task design; 2) Risk of error due to inadequate information; and 3) Risk associated with reduced safety and efficiency due to poor human factors design.

  1. Simulation of cerebrovascular circulation in the human cadaver for surgical neuroanatomy training. (United States)

    Güvençer, Mustafa; Sayhan, Salih; Ay Dereli, Nuran; Tetik, Süleyman; Yücesoy, Kemal; Arda, M Nuri


    The current progress in diagnostic and screening methods and surgical equipment technologies facilitates the accessibility to numerous anatomic structures through various interventional approaches. Consequently, the exact knowledge of the anatomic locations of neurovascular structures and their interactions may ensure that the surgical intervention is planned in the most appropriate way and the structures are accessed with the least complication risk during the intervention. A decapitated and formalin fixated whole-head of a male human cadaver kept for educational and research purposes in the Dokuz Eylul University Department of Anatomy was used in this study. Two separate reservoirs (for the arterial and the venous system) were connected to the Truno System 3 labeled perfusion pump. The reservoirs were filled with blue and red warm tap water. Colored tap water pumped on the right was emptied from the left. Continuous flow of the water in the closed-circuit arterial and venous systems was achieved. As the circulation was continuing, pterional craniotomy was performed and the dura mater was accessed and lifted under the Zeiss dissecting microscope. We believe that this model may contribute to neuroanatomy education and provide experience for the safe and ethical performance of surgical interventions during the intraoperative period.

  3. Virtual reality simulators for gastrointestinal endoscopy training (United States)

    Triantafyllou, Konstantinos; Lazaridis, Lazaros Dimitrios; Dimitriadis, George D


    The use of simulators as educational tools for medical procedures is spreading rapidly and many efforts have been made for their implementation in gastrointestinal endoscopy training. Endoscopy simulation training has been suggested for ascertaining patient safety while positively influencing the trainees’ learning curve. Virtual simulators are the most promising tool among all available types of simulators. These integrated modalities offer a human-like endoscopy experience by combining virtual images of the gastrointestinal tract and haptic realism with using a customized endoscope. From their first steps in the 1980s until today, research involving virtual endoscopic simulators can be divided in two categories: investigation of the impact of virtual simulator training in acquiring endoscopy skills and measuring competence. Emphasis should also be given to the financial impact of their implementation in endoscopy, including the cost of these state-of-the-art simulators and the potential economic benefits from their usage. Advances in technology will contribute to the upgrade of existing models and the development of new ones; while further research should be carried out to discover new fields of application.

  5. A review of the design and development processes of simulation for training in healthcare - A technology-centered versus a human-centered perspective. (United States)

    Persson, Johanna


    This article reviews literature about simulation systems for training in healthcare regarding the prevalence of human-centered approaches in the design and development of these systems, motivated by a tradition in this field of working technology-centered. The results show that the focus on human needs and context of use is limited. It is argued that a reduction of the focus on technical advancements in favor of the needs of the users and the healthcare community, underpinned by human factors and ergonomics theory, is favorable. Due to the low number of identified articles describing or discussing human-centered approaches it is furthermore concluded that the publication culture promotes technical descriptions and summative evaluations rather than descriptions and reflections regarding the design and development processes. Shifting the focus from a technology-centered approach to a human-centered one can aid in the process of creating simulation systems for training in healthcare that are: 1) relevant to the learning objectives, 2) adapted to the needs of users, context and task, and 3) not selected based on technical or fidelity criteria.

    Full Text Available Background: Extracorporeal membrane oxygenation (ECMO is a complex treatment. Despite this, there are a lack of training programs designed to develop relevant clinical and nonclinical skills required for ECMO specialists. The aim of the current study was to describe the design, implementation and evaluation of a 1-day simulation course for delivering training in ECMO. Methods: A 1-day simulation course was developed with educational and intensive care experts. First, the delegates received a lecture on the principles of simulation training and the importance of human factors. This was, followed by a practical demonstration and discussion of the ECMO circuit, console components, circuit interactions effects and potential complications. There were then five ECMO simulation scenarios with debriefing that covered technical and nontechnical issues. The course culminated in a knowledge-based assessment. Course outcomes were assessed using purpose-designed questionnaires. Results: We held 3 courses with a total of 14 delegates (9 intensive care nurses, 3 adult intensive care consultants and 2 ECMO technicians. Following the course, 8 (57% gained familiarity in troubleshooting an ECMO circuit, 6 (43% increased their familiarity with the ECMO pump and circuit, 8 (57% perceived an improvement in their communication skills and 7 (50% perceived an improvement in their leadership skills. At the end of the course, 13 (93% delegates agreed that they felt more confident in dealing with ECMO. Conclusions: Simulation-training courses may increase knowledge and confidence in dealing with ECMO emergencies. Further studies are indicated to determine whether simulation training improves clinical outcomes and translates to reduced complication rates in patients receiving ECMO.

  11. Human Factors in Training - Space Flight Resource Management Training (United States)

    Bryne, Vicky; Connell, Erin; Barshi, Immanuel; Arsintescu, L.


    Accidents and incidents show that high workload-induced stress and poor teamwork skills lead to performance decrements and errors. Research on teamwork shows that effective teams are able to adapt to stressful situations, and to reduce workload by using successful strategies for communication and decision making, and through dynamic redistribution of tasks among team members. Furthermore, superior teams are able to recognize signs and symptoms of workload-induced stress early, and to adapt their coordination and communication strategies to the high workload, or stress conditions. Mission Control Center (MCC) teams often face demanding situations in which they must operate as an effective team to solve problems with crew and vehicle during onorbit operations. To be successful as a team, flight controllers (FCers) must learn effective teamwork strategies. Such strategies are the focus of Space Flight Resource Management (SFRM) training. SFRM training in MOD has been structured to include some classroom presentations of basic concepts and case studies, with the assumption that skill development happens in mission simulation. Integrated mission simulations do provide excellent opportunities for FCers to practice teamwork, but also require extensive technical knowledge of vehicle systems, mission operations, and crew actions. Such technical knowledge requires lengthy training. When SFRM training is relegated to integrated simulations, FCers can only practice SFRM after they have already mastered the technical knowledge necessary for these simulations. Given the centrality of teamwork to the success of MCC, holding SFRM training till late in the flow is inefficient. But to be able to train SFRM earlier in the flow, the training cannot rely on extensive mission-specific technical knowledge. Hence, the need for a generic SFRM training framework that would allow FCers to develop basic teamwork skills which are mission relevant, but without the required mission knowledge

    The virtual physiological human (VPH) initiative encompasses a wide range of activities, including structural and functional imaging, data mining, knowledge discovery tool and database development, biomedical modelling, simulation and visualization. The VPH community is developing from a multitude of relatively focused, but disparate, research endeavours into an integrated effort to bring together, develop and translate emerging technologies for application, from academia to industry and medicine. This process initially builds on the evolution of multi-disciplinary interactions and abilities, but addressing the challenges associated with the implementation of the VPH will require, in the very near future, a translation of quantitative changes into a new quality of highly trained multi-disciplinary personnel. Current strategies for undergraduate and on-the-job training may soon prove insufficient for this. The European Commission seventh framework VPH network of excellence is exploring this emerging need, and is developing a framework of novel training initiatives to address the predicted shortfall in suitably skilled VPH-aware professionals. This paper reports first steps in the implementation of a coherent VPH training portfolio.

  13. Virtual reality simulator training of laparoscopic cholecystectomies - a systematic review. (United States)

    Ikonen, T S; Antikainen, T; Silvennoinen, M; Isojärvi, J; Mäkinen, E; Scheinin, T M


    Simulators are widely used in occupations where practice in authentic environments would involve high human or economic risks. Surgical procedures can be simulated by increasingly complex and expensive techniques. This review gives an update on computer-based virtual reality (VR) simulators in training for laparoscopic cholecystectomies. From leading databases (Medline, Cochrane, Embase), randomised or controlled trials and the latest systematic reviews were systematically searched and reviewed. Twelve randomised trials involving simulators were identified and analysed, as well as four controlled studies. Furthermore, seven studies comparing black boxes and simulators were included. The results indicated any kind of simulator training (black box, VR) to be beneficial at novice level. After VR training, novice surgeons seemed to be able to perform their first live cholecystectomies with fewer errors, and in one trial the positive effect remained during the first ten cholecystectomies. No clinical follow-up data were found. Optimal learning requires skills training to be conducted as part of a systematic training program. No data on the cost-benefit of simulators were found, the price of a VR simulator begins at EUR 60 000. Theoretical background to learning and limited research data support the use of simulators in the early phases of surgical training. The cost of buying and using simulators is justified if the risk of injuries and complications to patients can be reduced. Developing surgical skills requires repeated training. In order to achieve optimal learning a validated training program is needed.

Since interaction is conveyed by contact between the human body and the artifact, a computationally robust modeling approach for frictional contact forces is a crucial aspect. In this contribution, we propose a parametric contact model and formulate an associated force optimization problem to simultaneously estimate unknown muscle and contact forces in an inverse dynamic manner from a prescribed motion trajectory. Unlike existing work, we consider both the static and the kinetic regime of Coulomb's friction law. The approach is applied to the analysis of a leg extension training machine with the objective to reduce the stress on the tibiofemoral joint. The uncertainty of the simulation results due to a tunable parameter of the contact model is of particular interest.

    Larkin, Anne C; Cahan, Mitchell A; Whalen, Giles; Hatem, David; Starr, Susan; Haley, Heather-Lyn; Litwin, Demetrius; Sullivan, Kate; Quirk, Mark


    This study examines the development and implementation of a pilot human factors curriculum during a 2-year period. It is one component of a comprehensive 5-year human factors curriculum spanning core competencies of interpersonal and communication skills, systems-based practice, and professionalism and using low-and high-fidelity simulation techniques. Members of the Department of Surgery and the Center for Clinical Communication and Performance Outcomes jointly constructed a curriculum for PGY1 and PGY2 residents on topics ranging from challenging communication to time and stress management. Video demonstrations, triggers, and simulated scenarios involving acting patients were created by surgeons and medical educators. Pre- and postintervention measures were obtained for communication skills, perceived stress level, and teamwork. Communication skills were evaluated using a series of video vignettes. The validated Perceived Stress Scale and Teamwork and Patient Safety Attitudes survey were used. Residents' perceptions of the program were also measured. Twenty-seven PGY1 residents and 15 PGY2 residents participated during 2 years. Analyses of video vignette tests indicated significant improvement in empathic communication for PGY1 (t = 3.62, p = 0.001) and PGY2 (t = 5.00, p = 0.004). There were no significant changes to teamwork attitudes. Perceived levels of stress became considerably higher. PGY1 residents reported trying 1 to 3 strategies taught in the time management session, with 60% to 75% reporting improvement post-training. This unique and comprehensive human factors curriculum is shown to be effective in building communication competency for junior-level residents in the human and emotional aspects of surgical training and practice. Continued refinement and ongoing data acquisition and analyses are underway. Copyright 2010 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

  17. Virtual agents in a simulated virtual training environment (United States)

    Achorn, Brett; Badler, Norman L.


    A drawback to live-action training simulations is the need to gather a large group of participants in order to train a few individuals. One solution to this difficulty is the use of computer-controlled agents in a virtual training environment. This allows a human participant to be replaced by a virtual, or simulated, agent when only limited responses are needed. Each agent possesses a specified set of behaviors and is capable of limited autonomous action in response to its environment or the direction of a human trainee. The paper describes these agents in the context of a simulated hostage rescue training session, involving two human rescuers assisted by three virtual (computer-controlled) agents and opposed by three other virtual agents.

  20. Redesigned Human Metabolic Simulator (United States)

    Duffield, Bruce; Jeng, Frank; Lange, Kevin


    A design has been formulated for a proposed improved version of an apparatus that simulates atmospheric effects of human respiration by introducing controlled amounts of carbon dioxide, water vapor, and heat into the air. Denoted a human metabolic simulator (HMS), the apparatus is used for testing life-support equipment when human test subjects are not available. The prior version of the HMS, to be replaced, was designed to simulate the respiratory effects of as many as four persons. It exploits the catalytic combustion of methyl acetate, for which the respiratory quotient (the molar ratio of carbon dioxide produced to oxygen consumed) is very close to the human respiratory quotient of about 0.86. The design of the improved HMS provides for simulation of the respiratory effects of as many as eight persons at various levels of activity. The design would also increase safety by eliminating the use of combustion. The improved HMS (see figure) would include a computer that would exert overall control. The computer would calculate the required amounts of oxygen removal, carbon dioxide addition, water addition, and heat addition by use of empirical equations for metabolic profiles of respiration and heat. A blower would circulate air between the HMS and a chamber containing a life-support system to be tested. With the help of feedback from a mass flowmeter, the blower speed would be adjusted to regulate the rate of flow according to the number of persons to be simulated and to a temperature-regulation requirement (the air temperature would indirectly depend on the rate of flow, among other parameters). Oxygen would be removed from the circulating air by means of a commercially available molecular sieve configured as an oxygen concentrator. Oxygen, argon, and trace amounts of nitrogen would pass through a bed in the molecular sieve while carbon dioxide, the majority of nitrogen, and other trace gases would be trapped by the bed and subsequently returned to the chamber.

  4. Simulation training tools for nonlethal weapons using gaming environments (United States)

    Donne, Alexsana; Eagan, Justin; Tse, Gabriel; Vanderslice, Tom; Woods, Jerry


    Modern simulation techniques have a growing role for evaluating new technologies and for developing cost-effective training programs. A mission simulator facilitates the productive exchange of ideas by demonstration of concepts through compellingly realistic computer simulation. Revolutionary advances in 3D simulation technology have made it possible for desktop computers to process strikingly realistic and complex interactions with results depicted in real-time. Computer games now allow for multiple real human players and "artificially intelligent" (AI) simulated robots to play together. Advances in computer processing power have compensated for the inherent intensive calculations required for complex simulation scenarios. The main components of the leading game-engines have been released for user modifications, enabling game enthusiasts and amateur programmers to advance the state-of-the-art in AI and computer simulation technologies. It is now possible to simulate sophisticated and realistic conflict situations in order to evaluate the impact of non-lethal devices as well as conflict resolution procedures using such devices. Simulations can reduce training costs as end users: learn what a device does and doesn't do prior to use, understand responses to the device prior to deployment, determine if the device is appropriate for their situational responses, and train with new devices and techniques before purchasing hardware. This paper will present the status of SARA's mission simulation development activities, based on the Half-Life gameengine, for the purpose of evaluating the latest non-lethal weapon devices, and for developing training tools for such devices.

  5. Virtual reality: Avatars in human spaceflight training (United States)

    Osterlund, Jeffrey; Lawrence, Brad


    With the advancements in high spatial and temporal resolution graphics, along with advancements in 3D display capabilities to model, simulate, and analyze human-to-machine interfaces and interactions, the world of virtual environments is being used to develop everything from gaming, movie special affects and animations to the design of automobiles. The use of multiple object motion capture technology and digital human tools in aerospace has demonstrated to be a more cost effective alternative to the cost of physical prototypes, provides a more efficient, flexible and responsive environment to changes in the design and training, and provides early human factors considerations concerning the operation of a complex launch vehicle or spacecraft. United Space Alliance (USA) has deployed this technique and tool under Research and Development (R&D) activities on both spacecraft assembly and ground processing operations design and training on the Orion Crew Module. USA utilizes specialized products that were chosen based on functionality, including software and fixed based hardware (e.g., infrared and visible red cameras), along with cyber gloves to ensure fine motor dexterity of the hands. The key findings of the R&D were: mock-ups should be built to not obstruct cameras from markers being tracked; a mock-up toolkit be assembled to facilitate dynamic design changes; markers should be placed in accurate positions on humans and flight hardware to help with tracking; 3D models used in the virtual environment be striped of non-essential data; high computational capable workstations are required to handle the large model data sets; and Technology Interchange Meetings with vendors and other industries also utilizing virtual reality applications need to occur on a continual basis enabling USA to maintain its leading edge within this technology. Parameters of interest and benefit in human spaceflight simulation training that utilizes virtual reality technologies are to

    Sikder, Shameema; Tuwairqi, Khaled; Al-Kahtani, Eman; Myers, William G; Banerjee, Pat


    Virtual simulators have been widely implemented in medical and surgical training, including ophthalmology. The increasing number of published articles in this field mandates a review of the available results to assess current technology and explore future opportunities. A PubMed search was conducted and a total of 10 articles were reviewed. Virtual simulators have shown construct validity in many modules, successfully differentiating user experience levels during simulated phacoemulsification surgery. Simulators have also shown improvements in wet-lab performance. The implementation of simulators in the residency training has been associated with a decrease in cataract surgery complication rates. Virtual reality simulators are an effective tool in measuring performance and differentiating trainee skill level. Additionally, they may be useful in improving surgical skill and patient outcomes in cataract surgery. Future opportunities rely on taking advantage of technical improvements in simulators for education and research.

    Synchrophasor systems are being deployed in power systems throughout the North American Power Grid and there are plans to integrate this technology and its associated tools into Independent System Operator (ISO)/utility control room operations. A pre-requisite to using synchrophasor technologies in control rooms is for operators to obtain training and understand how to use this technology in real-time situations. The Phasor Simulator for Operator Training (PSOT) project objective was to develop, deploy and demonstrate a pre-commercial training simulator for operators on the use of this technology and to promote acceptance of the technology in utility and ISO/Regional Transmission Owner (RTO) control centers.

  12. The Role of Simulation in Microsurgical Training. (United States)

    Evgeniou, Evgenios; Walker, Harriet; Gujral, Sameer


    Simulation has been established as an integral part of microsurgical training. The aim of this study was to assess and categorize the various simulation models in relation to the complexity of the microsurgical skill being taught and analyze the assessment methods commonly employed in microsurgical simulation training. Numerous courses have been established using simulation models. These models can be categorized, according to the level of complexity of the skill being taught, into basic, intermediate, and advanced. Microsurgical simulation training should be assessed using validated assessment methods. Assessment methods vary significantly from subjective expert opinions to self-assessment questionnaires and validated global rating scales. The appropriate assessment method should carefully be chosen based on the simulation modality. Simulation models should be validated, and a model with appropriate fidelity should be chosen according to the microsurgical skill being taught. Assessment should move from traditional simple subjective evaluations of trainee performance to validated tools. Future studies should assess the transferability of skills gained during simulation training to the real-life setting. Copyright © 2017 Association of Program Directors in Surgery.

  14. Training together: how another human's presence affects behavior during virtual human-based team training

    Directory of Open Access Journals (Sweden)

    Andrew Robb


    Full Text Available Despite research showing that team training can lead to strong improvements in team performance, logistical difficulties can prevent team training programs from being adopted on a large scale. A proposed solution to these difficulties is the use of virtual humans to replace missing teammates. Existing research evaluating the use of virtual humans for team training has been conducted in settings involving a single human trainee. However, in the real world multiple human trainees would most likely train together. In this paper, we explore how the presence of a second human trainee can alter behavior during a medical team training program. Ninety-two nurses and surgical technicians participated in a medical training exercise, where they worked with a virtual surgeon and virtual anesthesiologist to prepare a simulated patient for surgery. The agency of the nurse and the surgical technician were varied between three conditions: human nurses and surgical technicians working together; human nurses working with a virtual surgical technician; and human surgical technicians working with a virtual nurse. Variations in agency did not produce statistically significant differences in the training outcomes, but several notable differences were observed in other aspects of the team's behavior. Specifically, when working with a virtual nurse, human surgical technicians were more likely to assist with speaking up about patient safety issues that were outside of their normal responsibilities; human trainees spent less time searching for a missing item when working with a virtual partner, likely because the virtual partner was physically unable to move throughout the room and assist with the searching process; and more breaks in presence were observed when two human teammates were present. These results show that some behaviors may be influenced by the presence of multiple human trainees, though these behaviors may not impinge on core training goals. When

  15. Development in Rubber Preparation for Endoscopic Training Simulator

    Directory of Open Access Journals (Sweden)

    D. Surangsrirat


    Full Text Available Endoscopy is one of the most important procedures in diagnosis and treatment of gastrointestinal tract problems. While endoscopic procedure has tremendous benefits, physicians require considerable practice and time to develop competency. Current endoscopic training process involves cognitive learning and hands-on training under the supervision of an expert gastroenterologist. Previous studies have shown that fellow involvement prolongs procedural time and incurs additional expenses to the institution. Moreover, the patient also experiences more discomfort and injury risk. Introduction of training simulator into the training process could reduce the involvement of the patients and thus reduce the risk. Porcine model is commonly used for training in endoscopy due to the similar tactile response to a human gastrointestinal tract. However, information on elastic behavior of pig or human gastrointestinal tract for the engineering purposes was limited. In this study, the modulus of elasticity and ultimate tensile stress data of the pig stomach and intestines, small and large intestines, were measured and compared with multiple rubber stomach and intestines models. Based on the experimental results and experienced gastroenterologists feedback, the proposed dipped rubber composition can provide a satisfactory tactile feedback and could be used to simulate a human gastrointestinal tract for an endoscopic simulation training model.

  16. Role of virtual simulation in surgical training. (United States)

    Zerbato, Davide; Dall'Alba, Diego


    The comparison of the developments obtained by training for aviation with the ones obtained by training for surgery highlights the efforts that are still required to define shared and validated training curricula for surgeons. This work focuses on robotic assisted surgery and the related training systems to analyze the current approaches to surgery training based on virtual environments. Limits of current simulation technology are highlighted and the systems currently on the market are compared in terms of their mechanical design and characteristics of the virtual environments offered. In particular the analysis focuses on the level of realism, both graphical and physical, and on the set of training tasks proposed. Some multimedia material is proposed to support the analysis and to highlight the differences between the simulations and the approach to training. From this analysis it is clear that, although there are several training systems on the market, some of them with a lot of scientific literature proving their validity, there is no consensus about the tasks to include in a training curriculum or the level of realism required to virtual environments to be useful.

  17. Human Factors in Training - Space Medicine Proficiency Training (United States)

    Connell, Erin; Arsintescu, Lucia


    The early Constellation space missions are expected to have medical capabilities very similar to those currently on the Space Shuttle and International Space Station (ISS). For Crew Exploration Vehicle (CEV) missions to ISS, medical equipment will be located on ISS, and carried into CEV in the event of an emergency. Flight Surgeons (FS) on the ground in Mission Control will be expected to direct the Crew Medical Officer (CMO) during medical situations. If there is a loss of signal and the crew is unable to communicate with the ground, a CMO would be expected to carry out medical procedures without the aid of a FS. In these situations, performance support tools can be used to reduce errors and time to perform emergency medical tasks. Work on medical training has been conducted in collaboration with the Medical Training Group at the Space Life Sciences Directorate and with Wyle Lab which provides medical training to crew members, Biomedical Engineers (BMEs), and to flight surgeons under the JSC Space Life Sciences Directorate s Bioastronautics contract. The space medical training work is part of the Human Factors in Training Directed Research Project (DRP) of the Space Human Factors Engineering (SHFE) Project under the Space Human Factors and Habitability (SHFH) Element of the Human Research Program (HRP). Human factors researchers at Johnson Space Center have recently investigated medical performance support tools for CMOs on-orbit, and FSs on the ground, and researchers at the Ames Research Center performed a literature review on medical errors. The work proposed for FY10 continues to build on this strong collaboration with the Space Medical Training Group and previous research. This abstract focuses on two areas of work involving Performance Support Tools for Space Medical Operations. One area of research building on activities from FY08, involved the feasibility of just-in-time (JIT) training techniques and concepts for real-time medical procedures. In Phase 1

    Transthoracic echocardiography (TTE) is finding increased use in anesthesia and critical care. Efficient options for training anesthesiologists should be explored. Simulator mannequins allow for training of manual acquisition and image recognition skills and may be suitable due to ease of scheduling. The authors tested the hypothesis that training with a simulator would not be inferior to training using a live volunteer. Prospective, randomized trial. University hospital. Forty-six anesthesia residents, fellows, and faculty. After preparation with a written and video tutorial, study subjects received 80 minutes of TTE training using either a simulator or live volunteer. Practical and written tests were completed before and after training to assess improvement in manual image acquisition skills and theoretic knowledge. The written test was repeated 4 weeks later. Performance in the practical image-acquisition test improved significantly after training using both the live volunteer and the simulator, improving by 4.0 and 4.3 points out of 15, respectively. Simulator training was found not to be inferior to live training, with a mean difference of -0.30 points and 95% confidence intervals that did not cross the predefined non-inferiority margin. Performance in the written retention test also improved significantly immediately after training for both groups but declined similarly upon repeat testing 4 weeks later. When providing initial TTE training to anesthesiologists, training using a simulator was not inferior to using live volunteers. Copyright © 2014 Elsevier Inc. All rights reserved.

    Roberto Rocha e Silva

    Full Text Available Abstract Objective: Introduce the low-cost and easy to purchase simulator without biological material so that any institution may promote extensive cardiovascular surgery training both in a hospital setting and at home without large budgets. Methods: A transparent plastic box is placed in a wooden frame, which is held by the edges using elastic bands, with the bottom turned upwards, where an oval opening is made, "simulating" a thoracotomy. For basic exercises in the aorta, the model presented by our service in the 2015 Brazilian Congress of Cardiovascular Surgery: a silicone ice tray, where one can train to make aortic purse-string suture, aortotomy, aortorrhaphy and proximal and distal anastomoses. Simulators for the training of valve replacement and valvoplasty, atrial septal defect repair and aortic diseases were added. These simulators are based on sewage pipes obtained in construction material stores and the silicone trays and ethyl vinyl acetate tissue were obtained in utility stores, all of them at a very low cost. Results: The models were manufactured using inert materials easily found in regular stores and do not present contamination risk. They may be used in any environment and maybe stored without any difficulties. This training enabled young surgeons to familiarize and train different surgical techniques, including procedures for aortic diseases. In a subjective assessment, these surgeons reported that the training period led to improved surgical techniques in the surgical field. Conclusion: The model described in this protocol is effective and low-cost when compared to existing simulators, enabling a large array of cardiovascular surgery training.

  6. Simulation training for hyperacute stroke unit nurses. (United States)

    Roots, Angela; Thomas, Libby; Jaye, Peter; Birns, Jonathan

    National clinical guidelines have emphasized the need to identify acute stroke as a clinical priority for early assessment and treatment of patients on hyperacute stroke units. Nurses working on hyperacute stroke units require stroke specialist training and development of competencies in dealing with neurological emergencies and working in multidisciplinary teams. Educational theory suggests that experiential learning with colleagues in real-life settings may provide transferable results to the workplace with improved performance. Simulation training has been shown to deliver situational training without compromising patient safety and has been shown to improve both technical and non-technical skills (McGaghie et al, 2010). This article describes the role that simulation training may play for nurses working on hyperacute stroke units explaining the modalities available and the educational potential. The article also outlines the development of a pilot course involving directly relevant clinical scenarios for hyperacute stroke unit patient care and assesses the benefits of simulation training for hyperacute stroke unit nurses, in terms of clinical performance and non-clinical abilities including leadership and communication.

    Directory of Open Access Journals (Sweden)

    Araki Toshitaka


    Full Text Available Abstract Background Basic clinical skills training in the Japanese medical education system has traditionally incorporated on-the-job training with patients. Recently, the complementary use of simulation techniques as part of this training has gained popularity. It is not known, however, whether the participants view this new type of education program favorably; nor is the impact of this program known. In this study we developed a new simulation-based training program in phlebotomy for new medical residents and assessed their satisfaction with the program Methods The education program comprised two main components: simulator exercise sessions and the actual drawing of blood from other trainees. At the end of the session, we surveyed participant sentiment regarding the program. Results There were 43 participants in total. In general, they were highly satisfied with the education program, with all survey questions receiving scores of 3 or more on a scale of 1–5 (mean range: 4.3 – 4.8, with 5 indicating the highest level of satisfaction. Additionally, their participation as a 'patient' for their co-trainees was undertaken willingly and was deemed to be a valuable experience. Conclusion We developed and tested an education program using a simulator for blood collection. We demonstrated a high satisfaction level among the participants for this unique educational program and expect that it will improve medical training, patient safety, and quality of care. The development and dissemination of similar educational programs involving simulation for other basic clinical skills will be undertaken in the future.

  11. Near-peer medical student simulation training. (United States)

    Cash, Thomas; Brand, Eleanor; Wong, Emma; Richardson, Jay; Athorn, Sam; Chowdhury, Faiza


    There is growing concern that medical students are inadequately prepared for life as a junior doctor. A lack of confidence managing acutely unwell patients is often cited as a barrier to good clinical care. With medical schools investing heavily in simulation equipment, we set out to explore if near-peer simulation training is an effective teaching format. Medical students in their third year of study and above were invited to attend a 90-minute simulation teaching session. The sessions were designed and delivered by final-year medical students using clinical scenarios mapped to the Sheffield MBChB curriculum. Candidates were required to assess, investigate and manage an acutely unwell simulated patient. Pre- and post-simulation training Likert scale questionnaires were completed relating to self-reported confidence levels. There is growing concern that medical students are inadequately prepared for life as a junior doctor RESULTS: Questionnaires were completed by 25 students (100% response rate); 52 per cent of students had no prior simulation experience. There were statistically significant improvements in self-reported confidence levels in each of the six areas assessed (p training benefits both teacher and learner and that this simplistic model could easily be replicated at other medical schools. As the most junior members of the team, medical students are often confined to observer status. Simulation empowers students to practise independently in a safe and protected environment. Furthermore, it may help to alleviate anxiety about starting work as a junior doctor and improve future patient care. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

  13. An advanced simulator for orthopedic surgical training. (United States)

    Cecil, J; Gupta, Avinash; Pirela-Cruz, Miguel


    The purpose of creating the virtual reality (VR) simulator is to facilitate and supplement the training opportunities provided to orthopedic residents. The use of VR simulators has increased rapidly in the field of medical surgery for training purposes. This paper discusses the creation of the virtual surgical environment (VSE) for training residents in an orthopedic surgical process called less invasive stabilization system (LISS) surgery which is used to address fractures of the femur. The overall methodology included first obtaining an understanding of the LISS plating process through interactions with expert orthopedic surgeons and developing the information centric models. The information centric models provided a structured basis to design and build the simulator. Subsequently, the haptic-based simulator was built. Finally, the learning assessments were conducted in a medical school. The results from the learning assessments confirm the effectiveness of the VSE for teaching medical residents and students. The scope of the assessment was to ensure (1) the correctness and (2) the usefulness of the VSE. Out of 37 residents/students who participated in the test, 32 showed improvements in their understanding of the LISS plating surgical process. A majority of participants were satisfied with the use of teaching Avatars and haptic technology. A paired t test was conducted to test the statistical significance of the assessment data which showed that the data were statistically significant. This paper demonstrates the usefulness of adopting information centric modeling approach in the design and development of the simulator. The assessment results underscore the potential of using VR-based simulators in medical education especially in orthopedic surgery.

  17. High-fidelity simulation enhances ACLS training. (United States)

    Langdorf, Mark I; Strom, Suzanne L; Yang, Luanna; Canales, Cecilia; Anderson, Craig L; Amin, Alpesh; Lotfipour, Shahram


    Medical student training and experience in cardiac arrest situations is limited. Traditional Advanced Cardiac Life Support (ACLS) teaching methods are largely unrealistic with rare personal experience as team leader. Yet Postgraduate Year 1 residents may perform this role shortly after graduation. We expanded our ACLS teaching to a "Resuscitation Boot Camp" where we taught 2010 ACLS to 19 pregraduation students in didactic (12 hours) and experiential (8 hours) format. Immediately before the course, we recorded students performing an acute coronary syndrome/ventricular fibrillation (VF) scenario. As a final test, we recorded the same scenario for each student. Primary outcomes were time to cardiopulmonary resuscitation (CPR) and defibrillation (DF). Secondary measures were total scenario score, dangerous actions, proportion of students voicing "ventricular fibrillation," 12-lead ST-elevation myocardial infarction (STEMI) interpretation, and care necessary for return of spontaneous circulation (ROSC). Two expert ACLS instructors scored both performances on a 121-point scale, with each student serving as their own control. We used t tests and McNemar tests for paired data with statistical significance at pmask ventilation before DF. After instruction, students scored 97±4/121 points (p<.0001) with no dangerous actions. Before training, only 4 of 19 (21%) students performed both CPR and DF within 2 minutes, and 3 of these had ROSC. After training, 14 of 19 (74%) achieved CPR+DF≤2 minutes (p=.002), and all had ROSC. Before training, 5 of 19 (26%) students said "VF" and 4 of 19 obtained an ECG, but none identified STEMI. After training, corresponding performance was 13 of 19 "VF" (68%, p=021) and 100% ECG and STEMI identification (p<.05). This course significantly improved knowledge and psychomotor skills. Critical actions required for resuscitation were much more common after training. ACLS training including high-fidelity simulation decreases time to CPR and DF and

  18. Intelligent dental training simulator with objective skill assessment and feedback. (United States)

    Rhienmora, Phattanapon; Haddawy, Peter; Suebnukarn, Siriwan; Dailey, Matthew N


    We present a dental training simulator that provides a virtual reality (VR) environment with haptic feedback for dental students to practice dental surgical skills in the context of a crown preparation procedure. The simulator addresses challenges in traditional training such as the subjective nature of surgical skill assessment and the limited availability of expert supervision. We identified important features for characterizing the quality of a procedure based on interviews with experienced dentists. The features are patterns combining tool position, tool orientation, and applied force. The simulator monitors these features during the procedure, objectively assesses the quality of the performed procedure using hidden Markov models (HMMs), and provides objective feedback on the user's performance in each stage of the procedure. We recruited five dental students and five experienced dentists to evaluate the accuracy of our skill assessment method and the quality of the system's generated feedback. The experimental results show that HMMs with selected features can correctly classify all test sequences into novice and expert categories. The evaluation also indicates a high acceptance rate from experts for the system's generated feedback. In this work, we introduce our VR dental training simulator and describe a mechanism for providing objective skill assessment and feedback. The HMM is demonstrated as an effective tool for classifying a particular operator as novice-level or expert-level. The simulator can generate tutoring feedback with quality comparable to the feedback provided by human tutors. Copyright © 2011 Elsevier B.V. All rights reserved.

  19. Simulation technology in training students, residents and faculty. (United States)

    Morgan, Pamela J; Cleave-Hogg, Doreen


    We provide an overview of the developments in medical education and assessment using high-fidelity simulation. Both descriptive and research papers recently published in the English language are included in this review. The majority of articles reviewed are descriptive in nature, outlining the use of simulation for various educational purposes in undergraduate, postgraduate and continuing medical education. Some articles focus on the use of simulation for the acquisition of technical skills in different surgical disciplines using part-task simulation. Other disciplines such as emergency medicine, critical care, paediatrics and nursing have also contributed to the literature in this area. Very little research in the area of simulation is evident in the literature addressing the actual value or the reliability and validity of high-fidelity simulation as an evaluation tool during this time period. A strong interest in decreasing human error and the improvement in patient safety may indicate the future direction of high-fidelity simulation. Simulation is receiving increasing support as an educational tool and in its use for evaluation purposes. Research into this area is still somewhat limited. As the research impetus increases in the future, we may see simulation as a major focus in all disciplines with respect to its use in the improvement of patient safety. Team training, including both personality and attitudinal issues similar to those performed in other high hazard industries, may become increasingly evident in the literature in the coming decade.

  20. Human motion simulation predictive dynamics

    CERN Document Server

    Abdel-Malek, Karim


    Simulate realistic human motion in a virtual world with an optimization-based approach to motion prediction. With this approach, motion is governed by human performance measures, such as speed and energy, which act as objective functions to be optimized. Constraints on joint torques and angles are imposed quite easily. Predicting motion in this way allows one to use avatars to study how and why humans move the way they do, given specific scenarios. It also enables avatars to react to infinitely many scenarios with substantial autonomy. With this approach it is possible to predict dynamic motion without having to integrate equations of motion -- rather than solving equations of motion, this approach solves for a continuous time-dependent curve characterizing joint variables (also called joint profiles) for every degree of freedom.

  2. Simulation-based team training in healthcare. (United States)

    Eppich, Walter; Howard, Valerie; Vozenilek, John; Curran, Ian


    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. We performed a selective review and critical synthesis of literature in healthcare simulation related to team learning as well as from other relevant disciplines such as psychology, business, and organizational behavior. We discuss appropriate use of SBTT and identify gaps in the literature. Healthcare educators should apply rigorous curriculum development processes and generate learning opportunities that address the interrelated conceptual levels of team working by addressing learning needs at the level of the individual, the team, the organization, and the healthcare system. The interplay between these conceptual levels and their relative importance to team-based learning should be explored and described. Instructional design factors and contextual features that impact the effect of SBTT should be studied. Further development of validated assessment tools of team performance relevant to professional practice is a high priority and is essential to provide formative, summative, and diagnostic feedback and evaluation of SBTT. Standardized reporting of curriculum design and debriefing approaches, although difficult, would help move the field forward by allowing educators to characterize effective SBTT instruction. Much work is needed to establish a robust and defensible evidence

  3. Development of VR simulator for nurse training (United States)

    Nakagawa, Y.; Tsetserukou, D.; Terashima, K.


    Our research focuses on the development of the VR simulator NurseSim to train nurse and hospital aides how to carry unconscious or injured person. The motivation behind this project is the fact that nurses consider patient lifting, transfer, and turning as most physically demanding. The user experiences the 3D environment in which they hold the subject. The task is to maintain such posture so that to prevent further injuries of the patient and distribute the weight of the patient over both hands evenly. Nurses are taught to mitigate and manage fatigue while at work.

  4. Virtual reality simulators and training in laparoscopic surgery. (United States)

    Yiannakopoulou, Eugenia; Nikiteas, Nikolaos; Perrea, Despina; Tsigris, Christos


    Virtual reality simulators provide basic skills training without supervision in a controlled environment, free of pressure of operating on patients. Skills obtained through virtual reality simulation training can be transferred on the operating room. However, relative evidence is limited with data available only for basic surgical skills and for laparoscopic cholecystectomy. No data exist on the effect of virtual reality simulation on performance on advanced surgical procedures. Evidence suggests that performance on virtual reality simulators reliably distinguishes experienced from novice surgeons Limited available data suggest that independent approach on virtual reality simulation training is not different from proctored approach. The effect of virtual reality simulators training on acquisition of basic surgical skills does not seem to be different from the effect the physical simulators. Limited data exist on the effect of virtual reality simulation training on the acquisition of visual spatial perception and stress coping skills. Undoubtedly, virtual reality simulation training provides an alternative means of improving performance in laparoscopic surgery. However, future research efforts should focus on the effect of virtual reality simulation on performance in the context of advanced surgical procedure, on standardization of training, on the possibility of synergistic effect of virtual reality simulation training combined with mental training, on personalized training.

  5. The influence of the adequacy of training simulators on simulator planning training (United States)

    Kuatov, B. Zh; Kemalov, B. K.; Yurkov, N. K.


    The analysis of the works with attempts to verify the adequacy of both simulation and simulators themselves was carried out. However, these attempts are limited by determining the facts of adequacy or inadequacy of checking systems that cannot be used to identify the skills acquired in accordance with the input of a generalized classification. Adequacy is a concomitant sign of inadequate use of simulators, however, the established base for assessing the adequacy of simulators does not allow presenting it in the form of the indicator of the accompanying sign of inadequacy of use of simulators. And the primary task is to determine its quantitative form, which would eliminate the disparity evaluations of teaching. This research paper presents the problems of the simulator training organization that regardless of the received ideas of flight missions planning, have the real objective, which is in conflict with an aircraft application, the essence of which is the presence of contradictions between the predicted and real necessary amount of forces and means to ensure the effectiveness. The paper aims at the adaptation of the content curriculum component for eliminating inadequate use of simulators, which should be focused on developing measures to compensate false skills in order to improve the accuracy of determining the flying skills in simulator training planning.

  6. Laparoscopic skills acquisition: a study of simulation and traditional training. (United States)

    Marlow, Nicholas; Altree, Meryl; Babidge, Wendy; Field, John; Hewett, Peter; Maddern, Guy J


    Training in basic laparoscopic skills can be undertaken using traditional methods, where trainees are educated by experienced surgeons through a process of graduated responsibility or by simulation-based training. This study aimed to assess whether simulation trained individuals reach the same level of proficiency in basic laparoscopic skills as traditional trained participants when assessed in a simulated environment. A prospective study was undertaken. Participants were allocated to one of two cohorts according to surgical experience. Participants from the inexperienced cohort were randomized to receive training in basic laparoscopic skills on either a box trainer or a virtual reality simulator. They were then assessed on the simulator on which they did not receive training. Participants from the experienced cohort, considered to have received traditional training in basic laparoscopic skills, did not receive simulation training and were randomized to either the box trainer or virtual reality simulator for skills assessment. The assessment scores from different cohorts on either simulator were then compared. A total of 138 participants completed the assessment session, 101 in the inexperienced simulation-trained cohort and 37 on the experienced traditionally trained cohort. There was no statistically significant difference between the training outcomes of simulation and traditionally trained participants, irrespective of the simulator type used. The results demonstrated that participants trained on either a box trainer or virtual reality simulator achieved a level of basic laparoscopic skills assessed in a simulated environment that was not significantly different from participants who had been traditionally trained in basic laparoscopic skills. © 2013 Royal Australasian College of Surgeons.

  7. Objective Validation of Perfusion-Based Human Cadaveric Simulation Training Model for Management of Internal Carotid Artery Injury in Endoscopic Endonasal Sinus and Skull Base Surgery. (United States)

    Shen, Jasper; Hur, Kevin; Zhang, Zhipeng; Minneti, Michael; Pham, Martin; Wrobel, Bozena; Zada, Gabriel


    The emergence of minimally invasive endoscopic endonasal skull base surgery has necessitated reproducible and realistic simulators of rare vascular injuries. To assess the face and content validity of an innovative perfusion-based cadaveric model developed to simulate internal carotid artery (ICA) injury during endoscopic surgery. Otolaryngology and neurosurgery trainees attempted 3 consecutive trials of endoscopic control of a parasellar ICA injury, with standardized technical feedback. Time to hemostasis (TTH) and blood loss were trended. All participants completed validated questionnaires using a 5-point Likert scale to assess the domains of confidence gain, face validity, content validity, and curriculum applicability. Among all participants (n = 35), TTH and mean blood loss significantly decreased between first vs second attempt (P = .005), and first vs third attempt (P = .03). Following the first attempt, trainees experienced an average 63% reduction in blood loss and 59% reduction in TTH. In the quartile of most improved participants, average blood loss reduction was 1115 mL (84% reduction) and TTH of 259 s (84% reduction). There were no significant differences between trainees of varying postgraduate year or specialty. Average pre and postprocedural confidence scores were 1.38 and 3.16, respectively (P < .0001). All trainees reported model realism, which achieved mean face validity 4.82 ± 0.41 and content validity 4.88 ± 0.33. The perfusion-based human cadaveric ICA injury model achieves high ratings of face and content validity across all levels of surgical trainees, and enables safe, realistic simulation for standardized skull base simulation and future curriculum development. Objective improvements in performance metrics may translate to improved patient outcomes.

    Mahmood, Haydar A; Botros, Nazeih M


    The goal of this study is to develop a synthesisable computer-simulated model that mimics the function of a simplified renal system. Hardware description language has been used to simulate the model. In future phase of this study, the model will be realised on an electronic chip such as 'Field Programmable Gate Arrays'. The simulated model introduces a dynamic representation of the human body fluid balance under normal conditions and displays the change of urine flow with the amount of ingested water. The inputs of the model are average values of parameters extracted from the renal system. Some of these parameters and variables are: arterial pressure, daily ingested fluid volume, daily ingested sodium, daily ingested potassium, extracellular fluid volume, intracellular fluid volume, renin concentration, angiotensin II concentration, and aldosterone concentration. Our results show that the output of the model is in agreement with those of the literatures.

    Jambon, A C; Dubecq-Princeteau, F; Dubois, P; Karpf, S; Chaillou, C; Meseure, P; Querleu, D


    There is much demand for laparoscopy training. We have developed a training simulator for initial training in gynecological laparoscopy. The simulator includes a mannequin with 3 located trocars, a PC and software for managing the graphical part of the training protocol. The objective is to learn how to achieve spatial localization and handle tools within the abdominal cavity. A series of exercises are proposed with increasing degree of difficulty. The simulator can be customized to simulate many different scenarios. The trainer must be present to provide an ultimate assessment of the trainee's experience. This new training tool cannot replace traditional surgical training but can help make it more efficient. The simulator is now being used by residents. Further technical developments are in progress to add further indispensable mechanical interactions (force feed back) to visualize the organ deformations and organ dissections within the abdominal cavity.

  19. Current status of endoscopic simulation in gastroenterology fellowship training programs. (United States)

    Jirapinyo, Pichamol; Thompson, Christopher C


    Recent guidelines have encouraged gastroenterology and surgical training programs to integrate simulation into their core endoscopic curricula. However, the role that simulation currently has within training programs is unknown. This study aims to assess the current status of simulation among gastroenterology fellowship programs. This questionnaire study consisted of 38 fields divided into two sections. The first section queried program directors' experience on simulation and assessed the current status of simulation at their institution. The second portion surveyed their opinion on the potential role of simulation on the training curriculum. The study was conducted at the 2013 American Gastroenterological Association Training Directors' Workshop in Phoenix, Arizona. The participants were program directors from Accreditation Council for Graduate Medical Education accredited gastroenterology training programs, who attended the workshop. The questionnaire was returned by 69 of 97 program directors (response rate of 71%). 42% of programs had an endoscopic simulator. Computerized simulators (61.5%) were the most common, followed by mechanical (30.8%) and animal tissue (7.7%) simulators, respectively. Eleven programs (15%) required fellows to use simulation prior to clinical cases. Only one program has a minimum number of hours fellows have to participate in simulation training. Current simulators are deemed as easy to use (76%) and good educational tools (65%). Problems are cost (72%) and accessibility (69%). The majority of program directors believe that there is a need for endoscopic simulator training, with only 8% disagreeing. Additionally, a majority believe there is a role for simulation prior to initiation of clinical cases with 15% disagreeing. Gastroenterology fellowship program directors widely recognize the importance of simulation. Nevertheless, simulation is used by only 42% of programs and only 15% of programs require that trainees use simulation prior to

    Pietsch, Urs; Ney, Ludwig; Kreuzer, Oliver; Berner, Armin; Lischke, Volker

    Mountain rescue operations often confront crews with extreme weather conditions. Extremely cold temperatures make standard treatment sometimes difficult or even impossible. It is well-known that most manual tasks, including those involved in mountain rescue operations, are slowed by extremely cold weather. To lessen and improve the decrement in performance of emergency medical treatment caused by cold-induced manual impairment and inadequate medical equipment and supplies, simulation training in a weather chamber, which can produce wind and temperatures up to -22°C, was developed. It provides a promising tool to train the management of complex multidisciplinary settings, thus reducing the occurrence of fatal human and technical errors and increasing the safety for both the patient and the mountain emergency medical service crew.

  5. Exploring the simulation requirements for virtual regional anesthesia training (United States)

    Charissis, V.; Zimmer, C. R.; Sakellariou, S.; Chan, W.


    This paper presents an investigation towards the simulation requirements for virtual regional anaesthesia training. To this end we have developed a prototype human-computer interface designed to facilitate Virtual Reality (VR) augmenting educational tactics for regional anaesthesia training. The proposed interface system, aims to compliment nerve blocking techniques methods. The system is designed to operate in real-time 3D environment presenting anatomical information and enabling the user to explore the spatial relation of different human parts without any physical constrains. Furthermore the proposed system aims to assist the trainee anaesthetists so as to build a mental, three-dimensional map of the anatomical elements and their depictive relationship to the Ultra-Sound imaging which is used for navigation of the anaesthetic needle. Opting for a sophisticated approach of interaction, the interface elements are based on simplified visual representation of real objects, and can be operated through haptic devices and surround auditory cues. This paper discusses the challenges involved in the HCI design, introduces the visual components of the interface and presents a tentative plan of future work which involves the development of realistic haptic feedback and various regional anaesthesia training scenarios.

    Yi, Sun Young; Ryu, Kum Hei; Na, Youn Ju; Woo, Hyun Soo; Ahn, Woojin; Kim, Woo Seok; Lee, Doo Yong


    The objective of this study is to determine whether targeted colonoscopy skills are acquired through simulation-based training using the KAIST-Ewha Colonoscopy Simulator II, and the acquired skills can be transferred to colonoscopy to actual patients. Eleven subjects consisting of six fellows and five residents participated in the study. The fellows and residents were divided into two groups, simulation-trained group and control group. Simulation-based training included practicing the targeted skills of colonoscopy using two training scenarios with different colon flexures and degrees of difficulty. The trainees were requested to practice until they reach all the established training goals. The both groups were evaluated during their colonoscopies to actual patients, which were performed under close supervision of colonoscopy experts. The results of this study show that the developed colonoscopy simulator is effective in teaching the targeted colonoscopy skills, and transferring those skills to actual colonoscopy.

  11. Progress in virtual reality simulators for surgical training and certification. (United States)

    de Visser, Hans; Watson, Marcus O; Salvado, Olivier; Passenger, Joshua D


    There is increasing evidence that educating trainee surgeons by simulation is preferable to traditional operating-room training methods with actual patients. Apart from reducing costs and risks to patients, training by simulation can provide some unique benefits, such as greater control over the training procedure and more easily defined metrics for assessing proficiency. Virtual reality (VR) simulators are now playing an increasing role in surgical training. However, currently available VR simulators lack the fidelity to teach trainees past the novice-to-intermediate skills level. Recent technological developments in other industries using simulation, such as the games and entertainment and aviation industries, suggest that the next generation of VR simulators should be suitable for training, maintenance and certification of advanced surgical skills. To be effective as an advanced surgical training and assessment tool, VR simulation needs to provide adequate and relevant levels of physical realism, case complexity and performance assessment. Proper validation of VR simulators and an increased appreciation of their value by the medical profession are crucial for them to be accepted into surgical training curricula.

  12. Role of simulation in training the next generation of endoscopists. (United States)

    Blackburn, Simon C; Griffin, Stephen J


    The use of simulation based training in endoscopy has been increasingly described, simulation has the potential reduce the harm caused to patients by novices performing procedures, increase efficiency by reducing the time needed to train in the clinical environment and increase the opportunity to repeatedly practice rare procedures as well as allowing the assessment of performance. Simulators can consist of mechanical devices, employ cadaveric animal tissue or use virtual reality technology. Simulators have been used to teach upper and lower gastrointestinal endoscopy as well as interventional procedures. This review reviews the currently available endoscopic simulators, and the evidence for their efficacy, demonstrating that the ability of simulators to differentiate between novice and expert endoscopists is well established. There is limited evidence for improved patient outcome as a result of simulation training. We also consider how the environment within which a simulation is placed can be manipulated to alter the learning achieved, broadening the scope of simulation to develop communication as well as technical skills. Finally the implications for future practice are considered; technology is likely improve the fidelity of simulators, increasing the potential for simulation to improve patient outcomes. The impact of the simulation environment, and the correct place of simulation within the training curriculum are both issues which need addressing.

  13. The Umbra Simulation and Integration Framework Applied to Emergency Response Training (United States)

    Hamilton, Paul Lawrence; Britain, Robert


    The Mine Emergency Response Interactive Training Simulation (MERITS) is intended to prepare personnel to manage an emergency in an underground coal mine. The creation of an effective training environment required realistic emergent behavior in response to simulation events and trainee interventions, exploratory modification of miner behavior rules, realistic physics, and incorporation of legacy code. It also required the ability to add rich media to the simulation without conflicting with normal desktop security settings. Our Umbra Simulation and Integration Framework facilitated agent-based modeling of miners and rescuers and made it possible to work with subject matter experts to quickly adjust behavior through script editing, rather than through lengthy programming and recompilation. Integration of Umbra code with the WebKit browser engine allowed the use of JavaScript-enabled local web pages for media support. This project greatly extended the capabilities of Umbra in support of training simulations and has implications for simulations that combine human behavior, physics, and rich media.

  14. Virtual reality simulation training for health professions trainees in gastrointestinal endoscopy. (United States)

    Walsh, Catharine M; Sherlock, Mary E; Ling, Simon C; Carnahan, Heather


    another method of virtual reality training (e.g. comparison of two different virtual reality simulators) were also included. Only trials measuring outcomes on humans in the clinical setting (as opposed to animals or simulators) were included. Two authors (CMS, MES) independently assessed the eligibility and methodological quality of trials, and extracted data on the trial characteristics and outcomes. Due to significant clinical and methodological heterogeneity it was not possible to pool study data in order to perform a meta-analysis. Where data were available for each continuous outcome we calculated standardized mean difference with 95% confidence intervals based on intention-to-treat analysis. Where data were available for dichotomous outcomes we calculated relative risk with 95% confidence intervals based on intention-to-treat-analysis. Thirteen trials, with 278 participants, met the inclusion criteria. Four trials compared simulation-based training with conventional patient-based endoscopy training (apprenticeship model) whereas nine trials compared simulation-based training with no training. Only three trials were at low risk of bias. Simulation-based training, as compared with no training, generally appears to provide participants with some advantage over their untrained peers as measured by composite score of competency, independent procedure completion, performance time, independent insertion depth, overall rating of performance or competency error rate and mucosal visualization. Alternatively, there was no conclusive evidence that simulation-based training was superior to conventional patient-based training, although data were limited. The results of this systematic review indicate that virtual reality endoscopy training can be used to effectively supplement early conventional endoscopy training (apprenticeship model) in diagnostic oesophagogastroduodenoscopy, colonoscopy and/or sigmoidoscopy for health professions trainees with limited or no prior endoscopic

  15. The CREST Simulation Development Process: Training the Next Generation. (United States)

    Sweet, Robert M


    The challenges of training and assessing endourologic skill have driven the development of new training systems. The Center for Research in Education and Simulation Technologies (CREST) has developed a team and a methodology to facilitate this development process. Backwards design principles were applied. A panel of experts first defined desired clinical and educational outcomes. Outcomes were subsequently linked to learning objectives. Gross task deconstruction was performed, and the primary domain was classified as primarily involving decision-making, psychomotor skill, or communication. A more detailed cognitive task analysis was performed to elicit and prioritize relevant anatomy/tissues, metrics, and errors. Reference anatomy was created using a digital anatomist and clinician working off of a clinical data set. Three dimensional printing can facilitate this process. When possible, synthetic or virtual tissue behavior and textures were recreated using data derived from human tissue. Embedded sensors/markers and/or computer-based systems were used to facilitate the collection of objective metrics. A learning Verification and validation occurred throughout the engineering development process. Nine endourology-relevant training systems were created by CREST with this approach. Systems include basic laparoscopic skills (BLUS), vesicourethral anastomosis, pyeloplasty, cystoscopic procedures, stent placement, rigid and flexible ureteroscopy, GreenLight PVP (GL Sim), Percutaneous access with C-arm (CAT), Nephrolithotomy (NLM), and a vascular injury model. Mixed modalities have been used, including "smart" physical models, virtual reality, augmented reality, and video. Substantial validity evidence for training and assessment has been collected on systems. An open source manikin-based modular platform is under development by CREST with the Department of Defense that will unify these and other commercial task trainers through the common physiology engine, learning

  16. Medical education and human trafficking: using simulation. (United States)

    Stoklosa, Hanni; Lyman, Michelle; Bohnert, Carrie; Mittel, Olivia


    Healthcare providers have the potential to play a crucial role in human trafficking prevention, identification, and intervention. However, trafficked patients are often unidentified due to lack of education and preparation available to healthcare professionals at all levels of training and practice. To increase victim identification in healthcare settings, providers need to be educated about the issue of trafficking and its clinical presentations in an interactive format that maximizes learning and ultimately patient-centered outcomes. In 2014, University of Louisville School of Medicine created a simulation-based medical education (SBME) curriculum to prepare students to recognize victims and intervene on their behalf. The authors share the factors that influenced the session's development and incorporation into an already full third year medical curriculum and outline the development process. The process included a needs assessment for the education intervention, development of objectives and corresponding assessment, implementation of the curriculum, and finally the next steps of the module as it develops further. Additional alternatives are provided for other medical educators seeking to implement similar modules at their home institution. It is our hope that the description of this process will help others to create similar interactive educational programs and ultimately help trafficking survivors receive the care they need.

  17. Virtual reality simulation training of mastoidectomy - studies on novice performance. (United States)

    Andersen, Steven Arild Wuyts


    Virtual reality (VR) simulation-based training is increasingly used in surgical technical skills training including in temporal bone surgery. The potential of VR simulation in enabling high-quality surgical training is great and VR simulation allows high-stakes and complex procedures such as mastoidectomy to be trained repeatedly, independent of patients and surgical tutors, outside traditional learning environments such as the OR or the temporal bone lab, and with fewer of the constraints of traditional training. This thesis aims to increase the evidence-base of VR simulation training of mastoidectomy and, by studying the final-product performances of novices, investigates the transfer of skills to the current gold-standard training modality of cadaveric dissection, the effect of different practice conditions and simulator-integrated tutoring on performance and retention of skills, and the role of directed, self-regulated learning. Technical skills in mastoidectomy were transferable from the VR simulation environment to cadaveric dissection with significant improvement in performance after directed, self-regulated training in the VR temporal bone simulator. Distributed practice led to a better learning outcome and more consolidated skills than massed practice and also resulted in a more consistent performance after three months of non-practice. Simulator-integrated tutoring accelerated the initial learning curve but also caused over-reliance on tutoring, which resulted in a drop in performance when the simulator-integrated tutor-function was discontinued. The learning curves were highly individual but often plateaued early and at an inadequate level, which related to issues concerning both the procedure and the VR simulator, over-reliance on the tutor function and poor self-assessment skills. Future simulator-integrated automated assessment could potentially resolve some of these issues and provide trainees with both feedback during the procedure and immediate

  18. Unannounced in situ simulations: integrating training and clinical practice. (United States)

    Walker, Susanna T; Sevdalis, Nick; McKay, Anthony; Lambden, Simon; Gautama, Sanjay; Aggarwal, Rajesh; Vincent, Charles


    Simulation-based training for healthcare providers is well established as a viable, efficacious training tool, particularly for the training of non-technical team-working skills. These skills are known to be critical to effective teamwork, and important in the prevention of error and adverse events in hospitals. However, simulation suites are costly to develop and releasing staff to attend training is often difficult. These factors may restrict access to simulation training. We discuss our experiences of 'in situ' simulation for unannounced cardiac arrest training when the training is taken to the clinical environment. This has the benefit of decreasing required resources, increasing realism and affordability, and widening multidisciplinary team participation, thus enabling assessment and training of non-technical team-working skills in real clinical teams. While there are practical considerations of delivering training in the clinical environment, we feel there are many potential benefits compared with other forms of simulation training. We are able to tailor the training to the needs of the location, enabling staff to see a scenario that is relevant to their practice. This is particularly useful for staff who have less exposure to cardiac arrest events, such as radiology staff. We also describe the important benefit of risk assessment for a clinical environment. During our simulations we have identified a number of issues that, had they occurred during a real resuscitation attempt, may have led to patient harm or patient death. For these reasons we feel in situ simulation should be considered by every hospital as part of a patient safety initiative.

  19. Live tissue versus simulation training for emergency procedures: Is simulation ready to replace live tissue? (United States)

    Barnes, Stephen L; Bukoski, Alex; Kerby, Jeffrey D; Llerena, Luis; Armstrong, John H; Strayhorn, Catherine


    Training of emergency procedures is challenging and application is not routine in all health care settings. The debate over simulation as an alternative to live tissue training continues with legislation before Congress to banish live tissue training in the Department of Defense. Little evidence exists to objectify best practice. We sought to evaluate live tissue and simulation-based training practices in 12 life-saving emergency procedures. In the study, 742 subjects were randomized to live tissue or simulation-training. Assessments of self-efficacy, cognitive knowledge, and psychomotor performance were completed pre- and post-training. Affective response to training was assessed through electrodermal activity. Subject matter experts gap analysis of live tissue versus simulation completed the data set. Subjects demonstrated pre- to post-training gains in self-efficacy, cognitive knowledge, psychomotor performance, and affective response regardless of training modality (P Affective response was greatest in live tissue training (P abandonment of live tissue training is not warranted. We maintain that combined live tissue and simulation-based training add value and should be continued. Congressional mandates may accelerate simulation development and improve performance.

  2. Human Factors in Training: Space Medical Proficiency Training (United States)

    Byrne, Vicky E.; Barshi, I.; Arsintescu, L.; Connell, E.


    The early Constellation space missions are expected to have medical capabilities very similar to those currently on the Space Shuttle and the International Space Station (ISS). For Crew Exploration Vehicle (CEV) missions to the ISS, medical equipment will be located on the ISS, and carried into CEV in the event of an emergency. Flight surgeons (FS) on the ground in Mission Control will be expected to direct the crew medical officer (CMO) during medical situations. If there is a loss of signal and the crew is unable to communicate with the ground, a CMO would be expected to carry out medical procedures without the aid of a FS. In these situations, performance support tools can be used to reduce errors and time to perform emergency medical tasks. The space medical training work is part of the Human Factors in Training Directed Research Project (DRP) of the Space Human Factors Engineering (SHFE) Project under the Space Human Factors and Habitability (SHFH) Element of the Human Research Program (HRP). This is a joint project consisting of human factors team from the Ames Research Center (ARC) with Immanuel Barshi as Principal Investigator and the Johnson Space Center (JSC). Human factors researchers at JSC have recently investigated medical performance support tools for CMOs on-orbit, and FSs on the ground, and researchers at the Ames Research Center performed a literature review on medical errors. Work on medical training has been conducted in collaboration with the Medical Training Group at the Johnson Space Center (JSC) and with Wyle Laboratories that provides medical training to crew members, biomedical engineers (BMEs), and to flight surgeons under the Bioastronautics contract. One area of research building on activities from FY08, involved the feasibility of just-in-time (JIT) training techniques and concepts for real-time medical procedures. A second area of research involves FS performance support tools. Information needed by the FS during the ISS mission

  3. Effects of virtual reality simulator training method and observational learning on surgical performance. (United States)

    Snyder, Christopher W; Vandromme, Marianne J; Tyra, Sharon L; Porterfield, John R; Clements, Ronald H; Hawn, Mary T


    Virtual reality (VR) simulators and Web-based instructional videos are valuable supplemental training resources in surgical programs, but it is unclear how to optimally integrate them into minimally invasive surgical training. Medical students were randomized to proficiency-based training on VR laparoscopy and endoscopy simulators by two different methods: proctored training (automated simulator feedback plus human expert feedback) or independent training (simulator feedback alone). After achieving simulator proficiency, trainees performed a series of laparoscopic and endoscopic tasks in a live porcine model. Prior to their entry into the animal lab, all trainees watched an instructional video of the procedure and were randomly assigned to either observe or not observe the actual procedure before performing it themselves. The joint effects of VR training method and procedure observation on time to successful task completion were evaluated with Cox regression models. Thirty-two students (16 proctored, 16 independent) completed VR training. Cox regression modeling with adjustment for relevant covariates demonstrated no significant difference in the likelihood of successful task completion for independent versus proctored training [Hazard Ratio (HR) 1.28; 95% Confidence Interval (CI) 0.96-1.72; p=0.09]. Trainees who observed the actual procedure were more likely to be successful than those who watched the instructional video alone (HR 1.47; 95% CI 1.09-1.98; p=0.01). Proctored VR training is no more effective than independent training with respect to surgical performance. Therefore, time-consuming human expert feedback during VR training may be unnecessary. Instructional videos, while useful, may not be adequate substitutes for actual observation when trainees are learning minimally invasive surgical procedures.

  4. [Effects of Training Students through a Program Simulating Medication Administration and Patient Instructions in Pre-training for Practical Training]. (United States)

    Kikuchi, Chigusa; Matsunaga, Tamihide; Suzuki, Tadashi


    Pharmacy school students were trained in a program simulating medication administration and giving adherence instructions. Following the training, the educational effects were evaluated. Students were separated into two groups. One group of students played the role of pharmacists and instructed simulated patients on medication adherence. Another group of students played the role of patients receiving simulated drug therapy; they were instructed on medication adherence by the students playing the role of pharmacists. The educational effects were evaluated using a questionnaire. The scores for "recognition of factors that influence medication adherence" tended to increase after the simulation, and they increased significantly after practical training. The scores for "self-evaluation of technique for instructing patients on medication adherence" increased significantly after the simulation, and they increased even more after practical training. The students' understanding of the effects on patients who were being instructed also increased significantly after the simulation, and these changes were maintained after practical training. In particular, students became more aware of the influence of pharmacists' attitudes. In practical training, the simulation training was helpful for bedside practice at hospital pharmacies and over-the-counter service at community pharmacies. Thus, the use of role play and simulated patients was an effective method for training pharmacy students to instruct patients on medication adherence.

  6. Cadaver-based training is superior to simulation training for cricothyrotomy and tube thoracostomy. (United States)

    Takayesu, James Kimo; Peak, David; Stearns, Dana


    Emergency medicine (EM) training mandates that residents be able to competently perform low-frequency critical procedures upon graduation. Simulation is the main method of training in addition to clinical patient care. Access to cadaver-based training is limited due to cost and availability. The relative fidelity and perceived value of cadaver-based simulation training is unknown. This pilot study sought to describe the relative value of cadaver training compared to simulation for cricothyrotomy and tube thoracostomy. To perform a pilot study to assess whether there is a significant difference in fidelity and educational experience of cadaver-based training compared to simulation training. To understand how important this difference is in training residents in low-frequency procedures. Twenty-two senior EM residents (PGY3 and 4) who had completed standard simulation training on cricothyrotomy and tube thoracostomy participated in a formalin-fixed cadaver training program. Participants were surveyed on the relative fidelity of the training using a 100 point visual analogue scale (VAS) with 100 defined as equal to performing the procedure on a real patient. Respondents were also asked to estimate how much the cadaveric training improved the comfort level with performing the procedures on a scale between 0 and 100 %. Open-response feedback was also collected. The response rate was 100 % (22/22). The average fidelity of the cadaver versus simulation training was 79.9 ± 7.0 vs. 34.7 ± 13.4 for cricothyrotomy (p training was rated as 78.5 ± 13.3 for tube thoracostomy and 78.7 ± 14.3 for cricothyrotomy. All respondents felt this difference in fidelity to be important for procedural training with 21/22 respondents specifically citing the importance of superior landmark and tissue fidelity compared to simulation training. Cadaver-based training provides superior landmark and tissue fidelity compared to simulation training and may be a valuable addition to EM

  8. Training for percutaneous renal access on a virtual reality simulator. (United States)

    Zhang, Yi; Yu, Cheng-fan; Liu, Jin-shun; Wang, Gang; Zhu, He; Na, Yan-qun


    The need to develop new methods of surgical training combined with advances in computing has led to the development of virtual reality surgical simulators. The PERC Mentor(TM) is designed to train the user in percutaneous renal collecting system access puncture. This study aimed to validate the use of this kind of simulator, in percutaneous renal access training. Twenty-one urologists were enrolled as trainees to learn a fluoroscopy-guided percutaneous renal accessing technique. An assigned percutaneous renal access procedure was immediately performed on the PERC Mentor(TM) after watching instruction video and an analog operation. Objective parameters were recorded by the simulator and subjective global rating scale (GRS) score were determined. Simulation training followed and consisted of 2 hours daily training sessions for 2 consecutive days. Twenty-four hours after the training session, trainees were evaluated performing the same procedure. The post-training evaluation was compared to the evaluation of the initial attempt. During the initial attempt, none of the trainees could complete the appointed procedure due to the lack of experience in fluoroscopy-guided percutaneous renal access. After the short-term training, all trainees were able to independently complete the procedure. Of the 21 trainees, 10 had primitive experience in ultrasound-guided percutaneous nephrolithotomy. Trainees were thus categorized into the group of primitive experience and inexperience. The total operating time and amount of contrast material used were significantly lower in the group of primitive experience versus the inexperience group (P = 0.03 and 0.02, respectively). The training on the virtual reality simulator, PERC Mentor(TM), can help trainees with no previous experience of fluoroscopy-guided percutaneous renal access to complete the virtual manipulation of the procedure independently. This virtual reality simulator may become an important training and evaluation tool in

    Full Text Available We begin by briefly situating the tradition of medical education in the West, noting the dichotomy between academic and clinical practice, especially in surgery. We note the change that occurred in medical education from the seventies of the twentieth century, with the implementation of the molecular biology paradigm in medicine. The training has become focused on components and intra-cellular structures, moving away from an integrated view of all human dimensions. Today we are witnessing a decline in skills of clinical practice training, in comparison with Western medical training until mid-twentieth century. The medical betting on scientific research, which is certainly commendable, has been causing, nevertheless, problems especially in the doctor-patient relationship; they have been worsening over the huge increase in chronic illnesses that require a lifelong contact between health professionals and patients. Reacting to this state of affairs, many universities around the world have introduced Humanities in medical training, broad term that can include everything from ethics and medical deontology to matters of literature or visual art, for example. The article describes briefly the three most common types of insertion of Humanities in Medicine. They are listed as: 1 - having a residual subject linked to the Humanities in the entire course of medicine; 2 - the Humanities in Medicine; 3 - Humanities in Medicine. After characterizing each one, we wonder which could actually promote a substantive difference in medical education and which is a farce in relation to that goal. Finally, we note that even the universities that use integrating models of humanities in medicine, they are constantly pressured to reduce the importance of this learning area at the development of scientific research which is required to report students in biochemical areas, for example. It is noted as a more fragile permanence of humanistic education the assessment of

    The Virtual Electrosurgical Skill Trainer is a tool for training surgeons the safe operation of electrosurgery tools in both open and minimally invasive surgery. This training includes a dedicated team-training module that focuses on operating room (OR) fire prevention and response. The module was developed to allow trainees, practicing surgeons, anesthesiologist, and nurses to interact with a virtual OR environment, which includes anesthesia apparatus, electrosurgical equipment, a virtual patient, and a fire extinguisher. Wearing a head-mounted display, participants must correctly identify the "fire triangle" elements and then successfully contain an OR fire. Within these virtual reality scenarios, trainees learn to react appropriately to the simulated emergency. A study targeted at establishing the face validity of the virtual OR fire simulator was undertaken at the 2015 Society of American Gastrointestinal and Endoscopic Surgeons conference. Forty-nine subjects with varying experience participated in this Institutional Review Board-approved study. The subjects were asked to complete the OR fire training/prevention sequence in the VEST simulator. Subjects were then asked to answer a subjective preference questionnaire consisting of sixteen questions, focused on the usefulness and fidelity of the simulator. On a 5-point scale, 12 of 13 questions were rated at a mean of 3 or greater (92%). Five questions were rated above 4 (38%), particularly those focusing on the simulator effectiveness and its usefulness in OR fire safety training. A total of 33 of the 49 participants (67%) chose the virtual OR fire trainer over the traditional training methods such as a textbook or an animal model. Training for OR fire emergencies in fully immersive VR environments, such as the VEST trainer, may be the ideal training modality. The face validity of the OR fire training module of the VEST simulator was successfully established on many aspects of the simulation.

  12. Midwifery students' experiences of simulation- and skills training. (United States)

    Lendahls, Lena; Oscarsson, Marie G


    In Sweden, simulation- and skills training are implemented in midwifery education in order to prepare students for clinical practice. Research regarding the use of both low to high levels of fidelity in simulation in midwifery programme is limited. The aim of this study was to explore midwifery students' experiences of simulation- and skills training. Midwifery students (n=61), at advanced level, were interviewed in 13 group interviews from 2011 to 2105. A semi-structured interview guide was used, and data were analysed by content analysis. The results are presented in four main categories: develops hands on skills and communication, power of collaborative learning, highly valued learning environment and facilitates clinical practice. The majority of students felt that the simulation- and skills training were necessary to become familiar with hands on skills. Having repetitive practices in a safe and secure environment was viewed as important, and students highly valued that mistakes could be made without fear of comprising patient safety. Student's collaboration, reflections and critical thinking increased learning ability. Simulation- and skills training created links between theory and practice, and the lecturer had an important role in providing instructions and feedback. Students felt prepared and confident before their clinical practice, and simulation- and skills training increased safety for all involved, resulting in students being more confident, as patients in clinical practice became less exposed. Furthermore, mentors were satisfied with students' basic skills. Simulation- and skills training support the development of midwifery skills. It creates links between theory and practice, which facilitates students' learning ability. Training needs to include reflections and critical thinking in order to develop their learning. The lecturer has an important role in encouraging time for reflections and creating safe environment during the skills and simulation

    Training and simulation are gaining importance in surgical education. Today, virtual reality surgery simulators provide sophisticated laparoscopic training scenarios and offer detailed assessment methods. This also makes simulators interesting for the application in surgical skills courses. The aim of the current study was to assess the suitability of a virtual surgery simulator for training and assessment in an established surgical training course. The study was conducted during the annual "Practical Course for Visceral Surgery" (Warnemuende, Germany). 36 of 108 course participants were assigned at random for the study. Training was conducted in 15 sessions over 5 days with 4 identical virtual surgery simulators (LapSim) and 2 standardised training tasks. The simulator measured 16 individual parameters and calculated 2 scores. Questionnaires were used to assess the test persons' laparoscopic experience, their training situation and the acceptance of the simulator training. Data were analysed with non-parametric tests. A subgroup analysis for laparoscopic experience was conducted in order to assess the simulator's construct validity and assessment capabilities. Median age was 32 (27 - 41) years; median professional experience was 3 (1 - 11) years. Typical laparoscopic learning curves with initial significant improvements and a subsequent plateau phase were measured over 5 days. The individual training sessions exhibited a rhythmic variability in the training results. A shorter night's sleep led to a marked drop in performance. The participants' different experience levels could clearly be discriminated ( ≤ 20 vs. > 20 laparoscopic operations; p ≤ 0.001). The questionnaire showed that the majority of the participants had limited training opportunities in their hospitals. The simulator training was very well accepted. However, the participants severely misjudged the real costs of the simulators that were used. The learning curve on the

  15. A High-Speed Train Operation Plan Inspection Simulation Model

    Directory of Open Access Journals (Sweden)

    Yang Rui


    Full Text Available We developed a train operation simulation tool to inspect a train operation plan. In applying an improved Petri Net, the train was regarded as a token, and the line and station were regarded as places, respectively, in accordance with the high-speed train operation characteristics and network function. Location change and running information transfer of the high-speed train were realized by customizing a variety of transitions. The model was built based on the concept of component combination, considering the random disturbance in the process of train running. The simulation framework can be generated quickly and the system operation can be completed according to the different test requirements and the required network data. We tested the simulation tool when used for the real-world Wuhan to Guangzhou high-speed line. The results showed that the proposed model can be developed, the simulation results basically coincide with the objective reality, and it can not only test the feasibility of the high-speed train operation plan, but also be used as a support model to develop the simulation platform with more capabilities.

  17. Incorporating simulation into gynecologic surgical training. (United States)

    Wohlrab, Kyle; Jelovsek, J Eric; Myers, Deborah


    Today's educational environment has made it more difficult to rely on the Halstedian model of "see one, do one, teach one" in gynecologic surgical training. There is decreased surgical volume, but an increased number of surgical modalities. Fortunately, surgical simulation has evolved to fill the educational void. Whether it is through skill generalization or skill transfer, surgical simulation has shifted learning from the operating room back to the classroom. This article explores the principles of surgical education and ways to introduce simulation as an adjunct to residency training. We review high- and low-fidelity surgical simulators, discuss the progression of surgical skills, and provide options for skills competency assessment. Time and money are major hurdles when designing a simulation curriculum, but low-fidelity models, intradepartmental cost sharing, and utilizing local experts for simulation proctoring can aid in developing a simulation program.

  18. Emotion, cognitive load and learning outcomes during simulation training. (United States)

    Fraser, Kristin; Ma, Irene; Teteris, Elise; Baxter, Heather; Wright, Bruce; McLaughlin, Kevin


    Simulation training has emerged as an effective way to complement clinical training of medical students. Yet outcomes from simulation training must be considered suboptimal when 25-30% of students fail to recognise a cardiac murmur on which they were trained 1 hour previously. There are several possible explanations for failure to improve following simulation training, which include the impact of heightened emotions on learning and cognitive overload caused by interactivity with high-fidelity simulators. This study was conducted to assess emotion during simulation training and to explore the relationships between emotion and cognitive load, and diagnostic performance. We trained 84 Year 1 medical students on a scenario of chest pain caused by symptomatic aortic stenosis. After training, students were asked to rate their emotional state and cognitive load. We then provided training on a dyspnoea scenario before asking participants to diagnose the murmur in which they had been trained (aortic stenosis) and a novel murmur (mitral regurgitation). We used factor analysis to identify the principal components of emotion, and then studied the associations between these components of emotion and cognitive load and diagnostic performance. We identified two principal components of emotion, which we felt represented invigoration and tranquillity. Both of these were associated with cognitive load with adjusted regression coefficients of 0.63 (95% confidence interval [CI] 0.28-0.99; p = 0.001) and - 0.44 (95% CI - 0.77 to - 0.10; p = 0.009), respectively. We found a significant negative association between cognitive load and the odds of subsequently identifying the trained murmur (odds ratio 0.27, 95% CI 0.11-0.67; p = 0.004). We found that increased invigoration and reduced tranquillity during simulation training were associated with increased cognitive load, and that the likelihood of correctly identifying a trained murmur declined with increasing cognitive load.

  19. Scripting Scenarios for the Human Patient Simulator (United States)

    Bacal, Kira; Miller, Robert; Doerr, Harold


    The Human Patient Simulator (HPS) is particularly useful in providing scenario-based learning which can be tailored to fit specific scenarios and which can be modified in realtime to enhance the teaching environment. Scripting these scenarios so as to maximize learning requires certain skills, in order to ensure that a change in student performance, understanding, critical thinking, and/or communication skills results. Methods: A "good" scenario can be defined in terms of applicability, learning opportunities, student interest, and clearly associated metrics. Obstacles to such a scenario include a lack of understanding of the applicable environment by the scenario author(s), a desire (common among novices) to cover too many topics, failure to define learning objectives, mutually exclusive or confusing learning objectives, unskilled instructors, poor preparation , disorganized approach, or an inappropriate teaching philosophy (such as "trial by fire" or education through humiliation). Results: Descriptions of several successful teaching programs, used in the military, civilian, and NASA medical environments , will be provided, along with sample scenarios. Discussion: Simulator-based lessons have proven to be a time- and cost-efficient manner by which to educate medical personnel. Particularly when training for medical care in austere environments (pre-hospital, aeromedical transport, International Space Station, military operations), the HPS can enhance the learning experience.

    Ma, Meng-Chao; Zhang, Yan; Li, Guang-Lei; Gao, Nan-Nan; Huang, Jin-Xin; Ma, Zhi-Guang; Shang, Ling-Ling; Guo, Liang-Feng


    This paper presents a three-dimensional (3D) interactive simulation training system based on holographic projection technology, nano-touch technology and interactive training mode, which realize the 3D display without stereoscopic glasses and touch type human computer interaction. 4 sets of holographic training courseware and 2 sets of fault presentation courseware was developed. Every courseware includes four parts: the cognition mode, the operation mode, the disassembling mode and daily maintenance mode. The system can carry out the training course of distribution automation equipment structure, disassembling and assembling, daily maintenance, operation, and the fault handling. A new training mode of power equipment training was created, which opened a new era of power equipment training.

  1. Human cadaver brain infusion model for neurosurgical training. (United States)

    Olabe, Jon; Olabe, Javier; Sancho, Vidal


    Microneurosurgical technique and anatomical knowledge require extensive laboratory training before mastering these skills. There are diverse training models based on synthetic materials, anesthetized animals, cadaver animals, or human cadaver. Human cadaver models are especially beneficial because they are the closest to live surgery with the greatest disadvantage of lacking hemodynamic factors. We developed the "brain infusion model" to provide a simple but realistic training method minimizing animal use or needs for special facilities. Four human cadaveric brains donated for educational purposes were explanted at autopsy. Carotids and vertebral arteries were cannulated with plastic tubes and fixed with suture. Water was flushed through the tubings until the whole arterial vasculature was observed as clean. The cannulated specimens were fixed with formaldehyde. Tap water infusion at a flow rate of 10 L/h was infused through the arterial tubings controlled with a drip regulator filling the arterial tree and leaking into the interstitial and cisternal space. Multiple microneurosurgical procedures were performed by 4 trainees. Cisternal and vascular dissection was executed in a very realistic fashion. Bypass anastomosis was created as well as aneurysm simulation with venous pouches. Vessel and aneurysm clipping and rupture situations were emulated and solution techniques were trained. Standard microsurgical laboratories regularly have scarce opportunities for working with decapitated human cadaver heads but could have human brains readily available. The human brain infusion model presents a realistic microneurosurgical training method. It is inexpensive and easy to set up. Such simplicity provides the adequate environment for developing microsurgical techniques. Copyright 2009 Elsevier Inc. All rights reserved.

  2. Operating Room Team Training with Simulation: A Systematic Review. (United States)

    Robertson, Jamie M; Dias, Roger D; Yule, Steven; Smink, Douglas S


    Nontechnical skills (NTS) such as teamwork and communication play an important role in preventing adverse outcomes in the operating room (OR). Simulation-based OR team training focused on these skills provides an environment where team members can learn with and from one another. We sought to conduct a systematic review to identify simulation-based approaches to NTS training for surgical teams. We conducted a systematic search of PubMed, ERIC, and the Cochrane Database using keywords and MeSH terms for studies describing simulation-based training for OR teams, including members from surgery, anesthesia, and nursing in September 2016. Information on the simulations, participants, and NTS assessments were abstracted from the articles meeting our search criteria. We identified 10 published articles describing simulation-based OR team-training programs focused on NTS. The primary focus of these programs was on communication, teamwork, leadership, and situation awareness. Only four of the programs used a validated instrument to assess the NTS of the individuals or teams participating in the simulations. Simulation-based OR team-training programs provide opportunities for NTS development and reflection by participants. Future programs could benefit from involving the full range of disciplines and professions that compose an OR team, as well as increased use of validated assessment instruments.

    Complex problem solving approaches and novel strategies employed by the military at the squad, team, and commander level are often best learned experimentally. Since live action exercises can be costly, advances in simulation game training technology offer exciting ways to enhance current training. Computer games provide an environment for active, critical learning. Games open up possibilities for simultaneous learning on multiple levels; players may learn from contextual information embedded in the dynamics of the game, the organic process generated by the game, and through the risks, benefits, costs, outcomes, and rewards of alternative strategies that result from decision making. In the present paper we discuss a multiplayer computer game simulation created for the Adaptive Thinking & Leadership (ATL) Program to train Special Forces Team Leaders. The ATL training simulation consists of a scripted single-player and an immersive multiplayer environment for classroom use which leverages immersive computer game technology. We define adaptive thinking as consisting of competencies such as negotiation and consensus building skills, the ability to communicate effectively, analyze ambiguous situations, be self-aware, think innovatively, and critically use effective problem solving skills. Each of these competencies is an essential element of leader development training for the U.S. Army Special Forces. The ATL simulation is used to augment experiential learning in the curriculum for the U.S. Army JFK Special Warfare Center & School (SWCS) course in Adaptive Thinking & Leadership. The school is incorporating the ATL simulation game into two additional training pipelines (PSYOPS and Civil Affairs Qualification Courses) that are also concerned with developing cultural awareness, interpersonal communication adaptability, and rapport-building skills. In the present paper, we discuss the design, development, and deployment of the training simulation, and emphasize how the

    The emergency cricothyroidotomy (EC) is a critical procedure. The high cost of failures increases the demand for evidence-based training methods. The aim of this study was to present and evaluate self-directed video-guided simulation training. Novice doctors were given an individual 1-h simulation...... training session. One month later, an EC on a cadaver was performed. All EC's were video recorded. An assessment tool was used to rate performance. Performance was compared with a pass/fail level for the EC. We found a high reliability, based on Pearson's r (0.88), and a significant progression of skill...

  5. Evaluation of surgical training in the era of simulation (United States)

    Shaharan, Shazrinizam; Neary, Paul


    AIM: To assess where we currently stand in relation to simulator-based training within modern surgical training curricula. METHODS: A systematic literature search was performed in PubMed database using keywords “simulation”, “skills assessment” and “surgery”. The studies retrieved were examined according to the inclusion and exclusion criteria. Time period reviewed was 2000 to 2013. The methodology of skills assessment was examined. RESULTS: Five hundred and fifteen articles focussed upon simulator based skills assessment. Fifty-two articles were identified that dealt with technical skills assessment in general surgery. Five articles assessed open skills, 37 assessed laparoscopic skills, 4 articles assessed both open and laparoscopic skills and 6 assessed endoscopic skills. Only 12 articles were found to be integrating simulators in the surgical training curricula. Observational assessment tools, in the form of Objective Structured Assessment of Technical Skills (OSATS) dominated the literature. CONCLUSION: Observational tools such as OSATS remain the top assessment instrument in surgical training especially in open technical skills. Unlike the aviation industry, simulation based assessment has only now begun to cross the threshold of incorporation into mainstream skills training. Over the next decade we expect the promise of simulator-based training to finally take flight and begin an exciting voyage of discovery for surgical trainees. PMID:25228946

  6. Flight Simulator Platform Motion and Air Transport Pilot Training (United States)

    Lee, Alfred T.; Bussolari, Steven R.


    The influence of flight simulator platform motion on pilot training and performance was examined In two studies utilizing a B-727-200 aircraft simulator. The simulator, located at Ames Research Center, Is certified by the FAA for upgrade and transition training in air carrier operations. Subjective ratings and objective performance of experienced B-727 pilots did not reveal any reliable effects of wide variations In platform motion de- sign. Motion platform variations did, however, affect the acquisition of control skill by pilots with no prior heavy aircraft flying experience. The effect was limited to pitch attitude control inputs during the early phase of landing training. Implications for the definition of platform motion requirements in air transport pilot training are discussed.

    Full Text Available Sanjay Konakondla, Reginald Fong, Clemens M Schirmer Department of Neurosurgery and Neuroscience Institute, Geisinger Medical Center, Geisinger Health System, Danville, PA, USA Abstract: The current simulation technology used for neurosurgical training leaves much to be desired. Significant efforts are thoroughly exhausted in hopes of developing simulations that translate to give learners the “real-life” feel. Though a respectable goal, this may not be necessary as the application for simulation in neurosurgical training may be most useful in early learners. The ultimate uniformly agreeable endpoint of improved outcome and patient safety drives these investments. We explore the development, availability, educational taskforces, cost burdens and the simulation advancements in neurosurgical training. The technologies can be directed at achieving early resident milestones placed by the Accreditation Council for Graduate Medical Education. We discuss various aspects of neurosurgery disciplines with specific technologic advances of simulation software. An overview of the scholarly landscape of the recent publications in the realm of medical simulation and virtual reality pertaining to neurologic surgery is provided. We analyze concurrent concept overlap between PubMed headings and provide a graphical overview of the associations between these terms.

    Full Text Available AIM: To assess the impact of the operational simulation training system on the cultivation of ophthalmic students. METHODS: Four hundred and eighty ophthalmic students in China Medical University from 2009 to 2011 were chosen as objects and divided into two groups at random. The students in the experimental group used operation simulation training system combined with traditional teaching methods, while the students in the control group only used traditional teaching methods. We examined the operation skills and the confidence of all the students half a year later. RESULTS: The improvement of the operation skills during the suture technique examination, and the confidence for operation technology were significantly different in two groups. The basic skills of the students in the examination groups improved apparently during the operational simulation training and they were full of confidence to their operational technique. CONCLUSION: The operational simulation training is useful for promoting the clinical ability for ophthalmic students and should be widely popularized.

  11. Endoscopic skills training in a simulated clinical setting. (United States)

    Fisher, Leon; Ormonde, Donald G; Riley, Richard H; Laurence, Bernard H


    We describe a simulation and scenario-based model of training in gastrointestinal endoscopic hemostasis, which combines acquisition of procedural and problem-solving skills in a close to reality simulated clinical setting. Two day courses in endoscopic hemostasis were conducted at the Clinical Training and Education Centre, the University of Western Australia, Perth, Australia. In total, 23 trainees were enrolled. The Erlangen Endo-Trainer simulator, porcine specimens of esophagus, stomach, and duodenum with a range of simulated bleeding sources, a separate catheter and a pump to simulate massive bleeding, and a full arm model with injectable veins were used. The SimMan monitor and software package were used to simulate hemodynamic parameters and electrocardiogram. Faculty members adjusted the rate of bleeding and vital parameters. The exercise was video recorded. On the first day, the group underwent simulator training in techniques of endoscopic hemostasis. On the second day, participants were scenario-based trained in full management of a "bleeding patient," which included resuscitation, sedation, endoscopy, and hemostasis, acting as leaders in teams of three. The course was evaluated by participants using a standardized questionnaire. A complex clinical setting of acute gastrointestinal bleeding was recreated with a high degree of realism. All participants reported that the simulated clinical scenario was a positive learning experience, helpful in managing complications and performing complex problem-solving tasks in a dynamic environment. Scenario and simulation-based training in endoscopic hemostasis may provide an opportunity to improve procedural skills and acquire practical experience in managing this medical emergency, which requires the ability to process, integrate, and adequately and quickly respond to complex information in unexpected conditions working as a team leader.

  12. Simulating human behavior for national security human interactions.

    Energy Technology Data Exchange (ETDEWEB)

    Bernard, Michael Lewis; Hart, Dereck H.; Verzi, Stephen J.; Glickman, Matthew R.; Wolfenbarger, Paul R.; Xavier, Patrick Gordon


    This 3-year research and development effort focused on what we believe is a significant technical gap in existing modeling and simulation capabilities: the representation of plausible human cognition and behaviors within a dynamic, simulated environment. Specifically, the intent of the ''Simulating Human Behavior for National Security Human Interactions'' project was to demonstrate initial simulated human modeling capability that realistically represents intra- and inter-group interaction behaviors between simulated humans and human-controlled avatars as they respond to their environment. Significant process was made towards simulating human behaviors through the development of a framework that produces realistic characteristics and movement. The simulated humans were created from models designed to be psychologically plausible by being based on robust psychological research and theory. Progress was also made towards enhancing Sandia National Laboratories existing cognitive models to support culturally plausible behaviors that are important in representing group interactions. These models were implemented in the modular, interoperable, and commercially supported Umbra{reg_sign} simulation framework.

  13. Central Line Proficiency Test Outcomes after Simulation Training versus Traditional Training to Competence. (United States)

    Alsaad, Ali A; Bhide, Vandana Y; Moss, Jimmy L; Silvers, Scott M; Johnson, Margaret M; Maniaci, Michael J


    Studies have shown the importance of simulation-based training on the outcomes of central venous catheter (CVC) insertion by trainees. To compare the performance of internal medicine trainees who underwent standardized simulation training of CVC insertion with that of internal medicine trainees who had traditional CVC training and were already deemed competent to perform the procedure during a proficiency evaluation using a training mannequin. Trainees who perform CVC insertion were enrolled in the institutional Central Line Workshop, which includes both an online and an experiential simulation component. The training is followed by a certification station proficiency assessment. Residents and fellows previously certified competent to perform CVC placement without supervision completed the online module, but they could opt out of the experiential component and proceed directly to the evaluation. Forty-eight trainees participated in the study. Twenty-one (44%), 15 (31%), 6 (13%), 1 (2%), 2 (4%), and 3 (6%) were in postgraduate year 1 (PGY1), PGY2, PGY3, PGY4, PGY5, and PGY6, respectively. Twenty-nine completed the hands-on instruction, 28 (97%) of whom successfully passed the simulation-based assessment on their first attempt. Nineteen trainees previously credentialed to perform CVC placement without supervision opted out of the simulation-based experiential training. Of these, five (26%) failed in their first attempt (P = 0.02 vs. trainees who completed the simulation training). Standardized simulation-based training can improve CVC insertion proficiency, even among trainees with previous experience sufficient to have been deemed competent in the procedure. Improved performance at simulation-based testing may translate to improved outcomes of CVC placement by trainees.

  14. Simulation based teaching in interventional radiology training: is it effective? (United States)

    Patel, R; Dennick, R


    To establish the educational effectiveness of simulation teaching in interventional radiology training. Electronic databases (MEDLINE, ERIC, Embase, OvidSP, and Cochrane Library) were searched (January 2000 to May 2015). Studies specifically with educational outcomes conducted on radiologists were eligible. All forms of simulation in interventional training were included. Data were extracted based on the population, intervention, comparison, and outcome (PICO) model. Kirkpatrick's hierarchy was used to establish educational intervention effectiveness. The quality of studies was assessed using the Cochrane risk of bias tool. Search resulted in 377 articles, of which 15 met the inclusion criteria. Thirteen of the 15 studies achieved level 2 of Kirkpatrick's hierarchy with only one reaching level 4. Statistically significant improvements in performance metrics as objective measures, demonstrating trainee competence were seen in 12/15 studies. Subjective improvements in confidence were noted in 13/15. Only one study demonstrated skills transferability and improvements in patient outcomes. Results demonstrate the relevance of simulated training to current education models in improving trainee competence; however, this is limited to the simulated environment as there is a lack of literature investigating its predictive validity and the effect on patient outcomes. The requirement for further research in this field is highlighted. Simulation is thus currently only deemed useful as an adjunct to current training models with the potential to play an influential role in the future of the interventional radiology training curriculum.

    Part of the U.S. Department of Energy’s Light Water Reactor Sustainability (LWRS) Program, the Risk-Informed Safety Margin Characterization (RISMC) Pathway develops approaches to estimating and managing safety margins. RISMC simulations pair deterministic plant physics models with probabilistic risk models. As human interactions are an essential element of plant risk, it is necessary to integrate human actions into the RISMC risk model. In this report, we review simulation-based and non-simulation-based human reliability assessment (HRA) methods. Chapter 2 surveys non-simulation-based HRA methods. Conventional HRA methods target static Probabilistic Risk Assessments for Level 1 events. These methods would require significant modification for use in dynamic simulation of Level 2 and Level 3 events. Chapter 3 is a review of human performance models. A variety of methods and models simulate dynamic human performance; however, most of these human performance models were developed outside the risk domain and have not been used for HRA. The exception is the ADS-IDAC model, which can be thought of as a virtual operator program. This model is resource-intensive but provides a detailed model of every operator action in a given scenario, along with models of numerous factors that can influence operator performance. Finally, Chapter 4 reviews the treatment of timing of operator actions in HRA methods. This chapter is an example of one of the critical gaps between existing HRA methods and the needs of dynamic HRA. This report summarizes the foundational information needed to develop a feasible approach to modeling human interactions in the RISMC simulations.

  17. Human factors in resuscitation: Lessons learned from simulator studies

    Directory of Open Access Journals (Sweden)

    Hunziker S


    Full Text Available Medical algorithms, technical skills, and repeated training are the classical cornerstones for successful cardiopulmonary resuscitation (CPR. Increasing evidence suggests that human factors, including team interaction, communication, and leadership, also influence the performance of CPR. Guidelines, however, do not yet include these human factors, partly because of the difficulties of their measurement in real-life cardiac arrest. Recently, clinical studies of cardiac arrest scenarios with high-fidelity video-assisted simulations have provided opportunities to better delineate the influence of human factors on resuscitation team performance. This review focuses on evidence from simulator studies that focus on human factors and their influence on the performance of resuscitation teams. Similar to studies in real patients, simulated cardiac arrest scenarios revealed many unnecessary interruptions of CPR as well as significant delays in defibrillation. These studies also showed that human factors play a major role in these shortcomings and that the medical performance depends on the quality of leadership and team-structuring. Moreover, simulated video-taped medical emergencies revealed that a substantial part of information transfer during communication is erroneous. Understanding the impact of human factors on the performance of a complex medical intervention like resuscitation requires detailed, second-by-second, analysis of factors involving the patient, resuscitative equipment such as the defibrillator, and all team members. Thus, high-fidelity simulator studies provide an important research method in this challenging field.

  20. Simulation in Canadian postgraduate emergency medicine training - a national survey. (United States)

    Russell, Evan; Hall, Andrew Koch; Hagel, Carly; Petrosoniak, Andrew; Dagnone, Jeffrey Damon; Howes, Daniel


    Simulation-based education (SBE) is an important training strategy in emergency medicine (EM) postgraduate programs. This study sought to characterize the use of simulation in FRCPC-EM residency programs across Canada. A national survey was administered to residents and knowledgeable program representatives (PRs) at all Canadian FRCPC-EM programs. Survey question themes included simulation program characteristics, the frequency of resident participation, the location and administration of SBE, institutional barriers, interprofessional involvement, content, assessment strategies, and attitudes about SBE. Resident and PR response rates were 63% (203/321) and 100% (16/16), respectively. Residents reported a median of 20 (range 0-150) hours of annual simulation training, with 52% of residents indicating that the time dedicated to simulation training met their needs. PRs reported the frequency of SBE sessions ranging from weekly to every 6 months, with 15 (94%) programs having an established simulation curriculum. Two (13%) of the programs used simulation for resident assessment, although 15 (94%) of PRs indicated that they would be comfortable with simulation-based assessment. The most common PR-identified barriers to administering simulation were a lack of protected faculty time (75%) and a lack of faculty experience with simulation (56%). Interprofessional involvement in simulation was strongly valued by both residents and PRs. SBE is frequently used by Canadian FRCPC-EM residency programs. However, there exists considerable variability in the structure, frequency, and timing of simulation-based activities. As programs transition to competency-based medical education, national organizations and collaborations should consider the variability in how SBE is administered.

  1. Technology and medicine: the evolution of virtual reality simulation in laparoscopic training. (United States)

    Bashir, Gareth


    Virtual reality (VR) simulation for laparoscopic surgical training is now a reality. There is increasing evidence that the use of VR simulation is a powerful adjunct to traditional surgical apprenticeship in the current climate of reduced time spent in training. This article reviews the early evidence supporting the case for VR simulation training in laparoscopic surgery. A standard literature search was conducted using the following phrases--'virtual reality in surgical training', 'surgical training', 'laparoscopic training' and 'simulation in surgical training'. This article outlines the early evidence which supports the use of VR simulation in laparoscopic training and the need for further research into this new training technique.

  5. Expanding the use of simulation in open vascular surgical training. (United States)

    Pandey, Vikas A; Wolfe, John H N


    Simulation technology has a well-defined role in nonmedical professions such as aviation and over the last two decades has permeated medical training. The most successful surgical simulation is in the fields of laparoscopic and endovascular surgery. These two-dimensional scenarios, as in the aviation industry, lend themselves to simulation. Open simulators have been met with more resistance than their laparoscopic counterparts because of the difficulties in simulating the three-dimensional field. Engaging in persistent practice is what makes the expert and all trainees should aspire to this. Without knowing, all surgical trainees have engaged in deliberate practice when first learning to tie surgical knots. This deliberate practice should be used in all aspects of vascular surgical practice, and it is no longer acceptable to perform procedures such as arterial anastomoses for the first time on patients. Simulators exist for all aspects of vascular surgical training and vary in complexity and price. Some of these simulators are suitable for use at home or in a skills laboratory whereas others are more suitable for use in a specialized skills center. Training on these simulators can be offered at a local level or at a regional level in the skills center. Where surgical procedures are not commonly performed or expertise is required for a new innovation, it is more appropriate to have national or internationally based workshops under the auspices of surgical boards or societies. Simulation of crisis management, well known in aviation, has also been applied to vascular surgical practice and can offer benefit to senior trainees even when their performance on a noncrisis simulator has reached a plateau. This article identifies the areas where simulation in open vascular surgery can benefit the trainee. Copyright © 2012. Published by Mosby, Inc.

  7. Simulation-based interpersonal communication skills training for neurosurgical residents. (United States)

    Harnof, Sagi; Hadani, Moshe; Ziv, Amitai; Berkenstadt, Haim


    Communication skills are an important component of the neurosurgery residency training program. We developed a simulation-based training module for neurosurgery residents in which medical, communication and ethical dilemmas are presented by role-playing actors. To assess the first national simulation-based communication skills training for neurosurgical residents. Eight scenarios covering different aspects of neurosurgery were developed by our team: (1) obtaining informed consent for an elective surgery, (2) discharge of a patient following elective surgery, (3) dealing with an unsatisfied patient, (4) delivering news of intraoperative complications, (5) delivering news of a brain tumor to parents of a 5 year old boy, (6) delivering news of brain death to a family member, (7) obtaining informed consent for urgent surgery from the grandfather of a 7 year old boy with an epidural hematoma, and (8) dealing with a case of child abuse. Fifteen neurosurgery residents from all major medical centers in Israel participated in the training. The session was recorded on video and was followed by videotaped debriefing by a senior neurosurgeon and communication expert and by feedback questionnaires. All trainees participated in two scenarios and observed another two. Participants largely agreed that the actors simulating patients represented real patients and family members and that the videotaped debriefing contributed to the teaching of professional skills. Simulation-based communication skill training is effective, and together with thorough debriefing is an excellent learning and practical method for imparting communication skills to neurosurgery residents. Such simulation-based training will ultimately be part of the national residency program.

  8. Models and Methods for Adaptive Management of Individual and Team-Based Training Using a Simulator (United States)

    Lisitsyna, L. S.; Smetyuh, N. P.; Golikov, S. P.


    Research of adaptive individual and team-based training has been analyzed and helped find out that both in Russia and abroad, individual and team-based training and retraining of AASTM operators usually includes: production training, training of general computer and office equipment skills, simulator training including virtual simulators which use computers to simulate real-world manufacturing situation, and, as a rule, the evaluation of AASTM operators’ knowledge determined by completeness and adequacy of their actions under the simulated conditions. Such approach to training and re-training of AASTM operators stipulates only technical training of operators and testing their knowledge based on assessing their actions in a simulated environment.

  9. Procedural wound geometry and blood flow generation for medical training simulators (United States)

    Aras, Rifat; Shen, Yuzhong; Li, Jiang


    Efficient application of wound treatment procedures is vital in both emergency room and battle zone scenes. In order to train first responders for such situations, physical casualty simulation kits, which are composed of tens of individual items, are commonly used. Similar to any other training scenarios, computer simulations can be effective means for wound treatment training purposes. For immersive and high fidelity virtual reality applications, realistic 3D models are key components. However, creation of such models is a labor intensive process. In this paper, we propose a procedural wound geometry generation technique that parameterizes key simulation inputs to establish the variability of the training scenarios without the need of labor intensive remodeling of the 3D geometry. The procedural techniques described in this work are entirely handled by the graphics processing unit (GPU) to enable interactive real-time operation of the simulation and to relieve the CPU for other computational tasks. The visible human dataset is processed and used as a volumetric texture for the internal visualization of the wound geometry. To further enhance the fidelity of the simulation, we also employ a surface flow model for blood visualization. This model is realized as a dynamic texture that is composed of a height field and a normal map and animated at each simulation step on the GPU. The procedural wound geometry and the blood flow model are applied to a thigh model and the efficiency of the technique is demonstrated in a virtual surgery scene.

  10. Focusing the research agenda for simulation training visual system requirements (United States)

    Lloyd, Charles J.


    Advances in the capabilities of the display-related technologies with potential uses in simulation training devices continue to occur at a rapid pace. Simultaneously, ongoing reductions in defense spending stimulate the services to push a higher proportion of training into ground-based simulators to reduce their operational costs. These two trends result in increased customer expectations and desires for more capable training devices, while the money available for these devices is decreasing. Thus, there exists an increasing need to improve the efficiency of the acquisition process and to increase the probability that users get the training devices they need at the lowest practical cost. In support of this need the IDEAS program was initiated in 2010 with the goal of improving display system requirements associated with unmet user needs and expectations and disrupted acquisitions. This paper describes a process of identifying, rating, and selecting the design parameters that should receive research attention. Analyses of existing requirements documents reveal that between 40 and 50 specific design parameters (i.e., resolution, contrast, luminance, field of view, frame rate, etc.) are typically called out for the acquisition of a simulation training display system. Obviously no research effort can address the effects of this many parameters. Thus, we developed a defensible strategy for focusing limited R&D resources on a fraction of these parameters. This strategy encompasses six criteria to identify the parameters most worthy of research attention. Examples based on display design parameters recommended by stakeholders are provided.

  11. Hybrid simulation using mixed reality for interventional ultrasound imaging training. (United States)

    Freschi, C; Parrini, S; Dinelli, N; Ferrari, M; Ferrari, V


    Ultrasound (US) imaging offers advantages over other imaging modalities and has become the most widespread modality for many diagnostic and interventional procedures. However, traditional 2D US requires a long training period, especially to learn how to manipulate the probe. A hybrid interactive system based on mixed reality was designed, implemented and tested for hand-eye coordination training in diagnostic and interventional US. A hybrid simulator was developed integrating a physical US phantom and a software application with a 3D virtual scene. In this scene, a 3D model of the probe with its relative scan plane is coherently displayed with a 3D representation of the phantom internal structures. An evaluation study of the diagnostic module was performed by recruiting thirty-six novices and four experts. The performances of the hybrid (HG) versus physical (PG) simulator were compared. After the training session, each novice was required to visualize a particular target structure. The four experts completed a 5-point Likert scale questionnaire. Seventy-eight percentage of the HG novices successfully visualized the target structure, whereas only 45% of the PG reached this goal. The mean scores from the questionnaires were 5.00 for usefulness, 4.25 for ease of use, 4.75 for 3D perception, and 3.25 for phantom realism. The hybrid US training simulator provides ease of use and is effective as a hand-eye coordination teaching tool. Mixed reality can improve US probe manipulation training.

  12. Debriefing 101: training faculty to promote learning in simulation-based training. (United States)

    Paige, John T; Arora, Sonal; Fernandez, Gladys; Seymour, Neal


    Debriefing is recognized as essential for successful simulation-based training. Unfortunately, its effective use is variable. We developed a train the trainer workshop to teach key evidence-based components of effective debriefing. A workshop focusing on best practices for debriefing in surgical simulation-based training was developed for the 2012 Annual Meeting of the Association for Surgical Education. Content emphasized key theoretical concepts related to and evidence-based components of an effective debriefing. Additionally, the workshop incorporated experiential learning via active debriefing following a simulated scenario. Content of the workshop emphasized effective debriefing as the key to learning in simulation-based education. Key elements of debriefing for educators to keep in mind include the following: approach, learning environment, engagement of learners, reaction, reflection, analysis, diagnosis, and application. Effective debriefing is an essential skill for educators involved in surgical simulation-based training. Without it, learning opportunities are missed. Training the trainer in effective debriefing is essential to ensure standardization of practice. Copyright © 2015 Elsevier Inc. All rights reserved.

  13. Training Knowledge Bots for Physics-Based Simulations Using Artificial Neural Networks (United States)

    Samareh, Jamshid A.; Wong, Jay Ming


    Millions of complex physics-based simulations are required for design of an aerospace vehicle. These simulations are usually performed by highly trained and skilled analysts, who execute, monitor, and steer each simulation. Analysts rely heavily on their broad experience that may have taken 20-30 years to accumulate. In addition, the simulation software is complex in nature, requiring significant computational resources. Simulations of system of systems become even more complex and are beyond human capacity to effectively learn their behavior. IBM has developed machines that can learn and compete successfully with a chess grandmaster and most successful jeopardy contestants. These machines are capable of learning some complex problems much faster than humans can learn. In this paper, we propose using artificial neural network to train knowledge bots to identify the idiosyncrasies of simulation software and recognize patterns that can lead to successful simulations. We examine the use of knowledge bots for applications of computational fluid dynamics (CFD), trajectory analysis, commercial finite-element analysis software, and slosh propellant dynamics. We will show that machine learning algorithms can be used to learn the idiosyncrasies of computational simulations and identify regions of instability without including any additional information about their mathematical form or applied discretization approaches.

  20. Surgical skills simulation in trauma and orthopaedic training. (United States)

    Stirling, Euan R B; Lewis, Thomas L; Ferran, Nicholas A


    Changing patterns of health care delivery and the rapid evolution of orthopaedic surgical techniques have made it increasingly difficult for trainees to develop expertise in their craft. Working hour restrictions and a drive towards senior led care demands that proficiency be gained in a shorter period of time whilst requiring a greater skill set than that in the past. The resulting conflict between service provision and training has necessitated the development of alternative methods in order to compensate for the reduction in 'hands-on' experience. Simulation training provides the opportunity to develop surgical skills in a controlled environment whilst minimising risks to patient safety, operating theatre usage and financial expenditure. Many options for simulation exist within orthopaedics from cadaveric or prosthetic models, to arthroscopic simulators, to advanced virtual reality and three-dimensional software tools. There are limitations to this form of training, but it has significant potential for trainees to achieve competence in procedures prior to real-life practice. The evidence for its direct transferability to operating theatre performance is limited but there are clear benefits such as increasing trainee confidence and familiarity with equipment. With progressively improving methods of simulation available, it is likely to become more important in the ongoing and future training and assessment of orthopaedic surgeons.

  4. INTEGRITY -- Integrated Human Exploration Mission Simulation Facility (United States)

    Henninger, D.; Tri, T.; Daues, K.

    It is proposed to develop a high -fidelity ground facil ity to carry out long-duration human exploration mission simulations. These would not be merely computer simulations - they would in fact comprise a series of actual missions that just happen to stay on earth. These missions would include all elements of an actual mission, using actual technologies that would be used for the real mission. These missions would also include such elements as extravehicular activities, robotic systems, telepresence and teleoperation, surface drilling technology--all using a simulated planetary landscape. A sequence of missions would be defined that get progressively longer and more robust, perhaps a series of five or six missions over a span of 10 to 15 years ranging in durat ion from 180 days up to 1000 days. This high-fidelity ground facility would operate hand-in-hand with a host of other terrestrial analog sites such as the Antarctic, Haughton Crater, and the Arizona desert. Of course, all of these analog mission simulations will be conducted here on earth in 1-g, and NASA will still need the Shuttle and ISS to carry out all the microgravity and hypogravity science experiments and technology validations. The proposed missions would have sufficient definition such that definitive requirements could be derived from them to serve as direction for all the program elements of the mission. Additionally, specific milestones would be established for the "launch" date of each mission so that R&D programs would have both good requirements and solid milestones from which to build their implementation plans. Mission aspects that could not be directly incorporated into the ground facility would be simulated via software. New management techniques would be developed for evaluation in this ground test facility program. These new techniques would have embedded metrics which would allow them to be continuously evaluated and adjusted so that by the time the sequence of missions is completed

  6. The Development of Dispatcher Training Simulator in a Thermal Energy Generation System (United States)

    Hakim, D. L.; Abdullah, A. G.; Mulyadi, Y.; Hasan, B.


    A dispatcher training simulator (DTS) is a real-time Human Machine Interface (HMI)-based control tool that is able to visualize industrial control system processes. The present study was aimed at developing a simulator tool for boilers in a thermal power station. The DTS prototype was designed using technical data of thermal power station boilers in Indonesia. It was then designed and implemented in Wonderware Intouch 10. The resulting simulator came with component drawing, animation, control display, alarm system, real-time trend, historical trend. This application used 26 tagnames and was equipped with a security system. The test showed that the principles of real-time control worked well. It is expected that this research could significantly contribute to the development of thermal power station, particularly in terms of its application as a training simulator for beginning dispatchers.

    Full Text Available In the work, the learning process with the use of a simulator was studied. In this case, both the design and algorithmic content of the simulator, as well as the trainee, must pass their part of the path, only in this case the result of learning is maximized. Theoretically, it is shown that the effectiveness of simulator training is primarily a function of the cognitive-operational and professional-personal aspects of the trainee's competence. The experiment confirmed that, despite the differences above the indicated qualities, the result can be estimated as the sum of their estimates.

  8. An augmented reality haptic training simulator for spinal needle procedures. (United States)

    Sutherland, Colin; Hashtrudi-Zaad, Keyvan; Sellens, Rick; Abolmaesumi, Purang; Mousavi, Parvin


    This paper presents the prototype for an augmented reality haptic simulation system with potential for spinal needle insertion training. The proposed system is composed of a torso mannequin, a MicronTracker2 optical tracking system, a PHANToM haptic device, and a graphical user interface to provide visual feedback. The system allows users to perform simulated needle insertions on a physical mannequin overlaid with an augmented reality cutaway of patient anatomy. A tissue model based on a finite-element model provides force during the insertion. The system allows for training without the need for the presence of a trained clinician or access to live patients or cadavers. A pilot user study demonstrates the potential and functionality of the system.

  9. Next Steps in the Evolution of Human Spaceflight Training (United States)

    Balmain, Clint; Niemann, Chris; McGregor, Darrell


    Train before you fly has always been a watchword at NASA, and consequently, NASA has been conducting training for human spaceflight missions for longer than it has been involved in the actual conduct of human spaceflight missions. Throughout that time, NASA s approach to human spaceflight training has continuously evolved to keep pace with the technology of the modern world, but the approach to training itself has not changed significantly. Today, there are more tools and technologies that enable learning than ever before. This paper intends to review the challenges of human spaceflight training and how modern technology and an updated approach could improve that training. The Spaceflight Training Management Office (DA7) within the Mission Operations Directorate (MOD) has been investigating the current training of instructors, flight controllers and astronauts in order to identify where a new approach to training and training management may be necessary to improve the efficacy of the training provided. Through this investigation, the DA7 team has identified potential areas of improvement within International Space Station (ISS) training in a wide range of areas, including the delivery of training, the structure of the training program, the concept of what is considered training, and the management of that training. The ISS is an operational program with an established training paradigm. As such, the implementation of these concepts will be met with several challenges that may prevent or preclude them from being adopted. These challenges include demonstrating return-on-investment (ROI) and overcoming cultural or technological obstacles. This report will delve into the possible improvement areas for training, the future training concepts that are being considered, and the challenges associated with implementation. The paper will include concepts for utilization of Web 2.0 technologies, electronic learning, digital media, and other technologies in the development

  11. Retention of Mastoidectomy Skills After Virtual Reality Simulation Training. (United States)

    Andersen, Steven Arild Wuyts; Konge, Lars; Cayé-Thomasen, Per; Sørensen, Mads Sølvsten


    The ultimate goal of surgical training is consolidated skills with a consistently high performance. However, surgical skills are heterogeneously retained and depend on a variety of factors, including the task, cognitive demands, and organization of practice. Virtual reality (VR) simulation is increasingly being used in surgical skills training, including temporal bone surgery, but there is a gap in knowledge on the retention of mastoidectomy skills after VR simulation training. To determine the retention of mastoidectomy skills after VR simulation training with distributed and massed practice and to investigate participants' cognitive load during retention procedures. A prospective 3-month follow-up study of a VR simulation trial was conducted from February 6 to September 19, 2014, at an academic teaching hospital among 36 medical students: 19 from a cohort trained with distributed practice and 17 from a cohort trained with massed practice. Participants performed 2 virtual mastoidectomies in a VR simulator a mean of 3.2 months (range, 2.4-5.0 months) after completing initial training with 12 repeated procedures. Practice blocks were spaced apart in time (distributed), or all procedures were performed in 1 day (massed). Performance of the virtual mastoidectomy as assessed by 2 masked senior otologists using a modified Welling scale, as well as cognitive load as estimated by reaction time to perform a secondary task. Among 36 participants, mastoidectomy final-product skills were largely retained at 3 months (mean change in score, 0.1 points; P = .89) regardless of practice schedule, but the group trained with massed practice took more time to complete the task. The performance of the massed practice group increased significantly from the first to the second retention procedure (mean change, 1.8 points; P = .001), reflecting that skills were less consolidated. For both groups, increases in reaction times in the secondary task (distributed practice group: mean

    We describe health care simulation, designed primarily for training, and provide examples of how human factors experts can collaborate with health care professionals and simulationists-experts in the design and implementation of simulation-to use contemporary simulation to improve health care delivery. The need-and the opportunity-to apply human factors expertise in efforts to achieve improved health outcomes has never been greater. Health care is a complex adaptive system, and simulation is an effective and flexible tool that can be used by human factors experts to better understand and improve individual, team, and system performance within health care. Expert opinion is presented, based on a panel delivered during the 2014 Human Factors and Ergonomics Society Health Care Symposium. Diverse simulators, physically or virtually representing humans or human organs, and simulation applications in education, research, and systems analysis that may be of use to human factors experts are presented. Examples of simulation designed to improve individual, team, and system performance are provided, as are applications in computational modeling, research, and lifelong learning. The adoption or adaptation of current and future training and assessment simulation technologies and facilities provides opportunities for human factors research and engineering, with benefits for health care safety, quality, resilience, and efficiency. Human factors experts, health care providers, and simulationists can use contemporary simulation equipment and techniques to study and improve health care delivery. © 2016, Human Factors and Ergonomics Society.

  14. Endoscopic submucosal dissection training with ex vivo human gastric remnants. (United States)

    Pham, David V; Shah, Anand; Borao, Frank J; Gorcey, Steven


    Endoscopic submucosal dissection (ESD) offers en bloc resection of early cancer or precancerous lesions, potentially saving patients from major organ resection, such as gastrectomy, colectomy, and esophagectomy. Japan now leads the world in ESD due to its high rate of gastric cancer. Western countries, with their lower gastric cancer rates, do not get as much experience with the technique. Training in ESD utilizing both in vivo and ex vivo porcine stomach has been shown to decrease rates of perforation and operative time. Both models can be prohibitively expensive or not generally available to the majority of endoscopists on a regular basis. This study describes the framework for using human gastric remnants from sleeve gastrectomy patients for ESD training. Patients undergoing sleeve gastrectomy for morbid obesity were consented for use of their gastric specimen before surgery. The specimen was weighed and measured by the pathologist and then used for ESD training. The specimen was mounted to a 15-mm laparoscopic port and secured using a pursestring suture. ESD was then performed through this port. We were able to successfully use this model to resect multiple marked out lesions in an en bloc fashion. Training using this model has improved our dissection times from approximately 2 h to 30 min for a 2-cm simulated lesion. ESD requires the endoscopist to perform a surgical dissection. Until now, development of these skills required intensive training on porcine models that are not widely available. We were able to create a method using the excised portion from sleeve gastrectomy patients, providing a more accessible and cost-effective model for ESD training and potentially other endoscopic therapeutic modalities.

  15. Designing simulator tools for rail research: the case study of a train driving microworld. (United States)

    Naweed, A; Hockey, G R J; Clarke, S D


    The microworld simulator paradigm is well established in the areas of ship-navigation and spaceflight, but has yet to be applied to rail. This paper presents a case study aiming to address this research gap, and describes the development of a train driving microworld as a tool to overcome some common research barriers. A theoretical framework for microworld design is tested and used to explore some key methodological issues and characteristics of train driving, enhancing theory development and providing a useful guideline for the designers of other collision-avoidance systems. A detailed description is given of the ATREIDES (Adaptive Train Research Enhanced Information Display & Environment Simulator) microworld, which simulates the work environment of a train driver in a high-speed passenger train. General indications of the testable driving scenarios that may be simulated are given, and an example of an ATREIDES-based study is presented to illustrate its applied research potential. The article concludes with a review of the design process, considers some strengths and limitations, and explores some future initiatives towards enhancing the systematic study of rail research in the human factors community.

  16. Simulation Training in Obstetrics and Gynaecology Residency Programs in Canada. (United States)

    Sanders, Ari; Wilson, R Douglas


    The integration of simulation into residency programs has been slower in obstetrics and gynaecology than in other surgical specialties. The goal of this study was to evaluate the current use of simulation in obstetrics and gynaecology residency programs in Canada. A 19-question survey was developed and distributed to all 16 active and accredited obstetrics and gynaecology residency programs in Canada. The survey was sent to program directors initially, but on occasion was redirected to other faculty members involved in resident education or to senior residents. Survey responses were collected over an 18-month period. Twelve programs responded to the survey (11 complete responses). Eleven programs (92%) reported introducing an obstetrics and gynaecology simulation curriculum into their residency education. All respondents (100%) had access to a simulation centre. Simulation was used to teach various obstetrical and gynaecological skills using different simulation modalities. Barriers to simulation integration were primarily the costs of equipment and space and the need to ensure dedicated time for residents and educators. The majority of programs indicated that it was a priority for them to enhance their simulation curriculum and transition to competency-based resident assessment. Simulation training has increased in obstetrics and gynaecology residency programs. The development of formal simulation curricula for use in obstetrics and gynaecology resident education is in early development. A standardized national simulation curriculum would help facilitate the integration of simulation into obstetrics and gynaecology resident education and aid in the shift to competency-based resident assessment. Obstetrics and gynaecology residency programs need national collaboration (between centres and specialties) to develop a standardized simulation curriculum for use in obstetrics and gynaecology residency programs in Canada.

  17. Modeling and simulating human teamwork behaviors using intelligent agents (United States)

    Fan, Xiaocong; Yen, John


    Among researchers in multi-agent systems there has been growing interest in using intelligent agents to model and simulate human teamwork behaviors. Teamwork modeling is important for training humans in gaining collaborative skills, for supporting humans in making critical decisions by proactively gathering, fusing, and sharing information, and for building coherent teams with both humans and agents working effectively on intelligence-intensive problems. Teamwork modeling is also challenging because the research has spanned diverse disciplines from business management to cognitive science, human discourse, and distributed artificial intelligence. This article presents an extensive, but not exhaustive, list of work in the field, where the taxonomy is organized along two main dimensions: team social structure and social behaviors. Along the dimension of social structure, we consider agent-only teams and mixed human-agent teams. Along the dimension of social behaviors, we consider collaborative behaviors, communicative behaviors, helping behaviors, and the underpinning of effective teamwork-shared mental models. The contribution of this article is that it presents an organizational framework for analyzing a variety of teamwork simulation systems and for further studying simulated teamwork behaviors.

  18. Detailed Numerical Simulation of the Graniteville Train Collision

    Energy Technology Data Exchange (ETDEWEB)

    Buckley, R. L.


    An unfortunate accident occurred in Graniteville, South Carolina on 6 January, 2005 when a train carrying a variety of hazardous chemicals collided with a stationary train parked on a siding rail (spur). The Savannah River National Laboratory (SRNL) runs prognostic atmospheric simulations of the Central Savannah River Area (CSRA) on an operational basis in the event of such airborne releases. Although forecast information was provided at 2-km horizontal grid spacing during the accident response, a higher-resolution simulation was later performed to examine influences of local topography on plume migration. The Regional Atmospheric Modeling System (RAMS, version 4.3.0) was used to simulate meteorology using multiple grids with an innermost grid spacing of 125 meters. This report discusses comparisons of simulated meteorology with local observations and applications using two separate transport models. Results from the simulations are shown to generally agree with meteorological observations at the time. Use of a dense gas model to simulate localized effects indicates agreement with fatalities in the immediate area and visible damage to vegetation.

  19. [Crew resource management and simulator training in acute stroke therapy]. (United States)

    Tahtali, D; Bohmann, F; Rostek, P; Misselwitz, B; Reihs, A; Heringer, F; Jahnke, K; Steinmetz, H; Pfeilschifter, W


    Time is of critical importance in acute stroke management. The establishment of thrombectomy now adds to the complexity and interdisciplinarity of the initial phase. In non-medical high-fidelity situations, such as aviation, crew resource management (CRM) has proven to be highly efficient. It has therefore also been implemented in professional cardiovascular life support training. In a setting where every minute counts, CRM and regular training of the high-fidelity stroke team could offer ways to improve treatment of acute stroke patients. We evaluated the effects of a CRM-based stroke team with regular simulation training on the quality of care (e.g. door to needle time and thrombolysis rate) as well as on staff satisfaction and perceived patient safety in the emergency department of a tertiary care neurocenter. We implemented a dedicated stroke team consisting of 7 persons who are notified by a collective call via speed dial and conceived a simulator-based team training for all new stroke team members which we conduct at monthly intervals. We recorded door to needle times of all consecutive patients, staff satisfaction in the emergency room and the acceptance of this new learning format. This approach led to a relevant and sustained reduction of the mean door to needle time to less than 30 min. It improved perceived patient safety in residents with professional experience of less than 2 years. There was a very high acceptance within the stroke team training and staff and its usefulness was judged to be very high. Even though our data do not allow positive effects on patient outcomes to be inferred, the implementation of a CRM-based stroke team and simulator training has had multiple positive effects on the workflow and work satisfaction in the treatment of acute stroke patients.

  20. Capturing differences in dental training using a virtual reality simulator. (United States)

    Mirghani, I; Mushtaq, F; Allsop, M J; Al-Saud, L M; Tickhill, N; Potter, C; Keeling, A; Mon-Williams, M A; Manogue, M


    Virtual reality simulators are becoming increasingly popular in dental schools across the world. But to what extent do these systems reflect actual dental ability? Addressing this question of construct validity is a fundamental step that is necessary before these systems can be fully integrated into a dental school's curriculum. In this study, we examined the sensitivity of the Simodont (a haptic virtual reality dental simulator) to differences in dental training experience. Two hundred and eighty-nine participants, with 1 (n = 92), 3 (n = 79), 4 (n = 57) and 5 (n = 61) years of dental training, performed a series of tasks upon their first exposure to the simulator. We found statistically significant differences between novice (Year 1) and experienced dental trainees (operationalised as 3 or more years of training), but no differences between performance of experienced trainees with varying levels of experience. This work represents a crucial first step in understanding the value of haptic virtual reality simulators in dental education. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  4. SIDH: A Game-Based Architecture for a Training Simulator

    Directory of Open Access Journals (Sweden)

    P. Backlund


    Full Text Available Game-based simulators, sometimes referred to as “lightweight” simulators, have benefits such as flexible technology and economic feasibility. In this article, we extend the notion of a game-based simulator by introducing multiple screen view and physical interaction. These features are expected to enhance immersion and fidelity. By utilizing these concepts we have constructed a training simulator for breathing apparatus entry. Game hardware and software have been used to produce the application. More important, the application itself is deliberately designed to be a game. Indeed, one important design goal is to create an entertaining and motivating experience combined with learning goals in order to create a serious game. The system has been evaluated in cooperation with the Swedish Rescue Services Agency to see which architectural features contribute to perceived fidelity. The modes of visualization and interaction as well as level design contribute to the usefulness of the system.

  6. Innovative transesophageal echocardiography training and competency assessment for Chinese anesthesiologists: role of transesophageal echocardiography simulation training. (United States)

    Song, Haibo; Peng, Yong G; Liu, Jin


    Transesophageal echocardiography (TEE) is playing an invaluable role in diagnosing and monitoring the patient's hemodynamics in both cardiac and noncardiac surgery. There have been many obstacles in TEE training. The TEE simulation provides an ideal environment for anesthesiologists to practice their echocardiography skills out of the operation room. It consists of a manikin and a dummy probe that enable the trainees to perform a hands-on operation with echocardiographic views and allow a virtual scene consisting of a three-dimensional cardiac model, probe tip and image plane be presented side by side simultaneously. The TEE simulator provides an easy comprehensive learning interface and a friendly environment without the psychological pressure and time limitation frequently experienced in the operation room. The simulator can also be used to assess and evaluate the trainees' manipulation skills, space thinking, and clinical judgment ability. TEE simulation-based training and testing can be an important part in TEE training curriculum before the trainees start their clinical training in the operation room.

  8. The importance of expert feedback during endovascular simulator training. (United States)

    Boyle, Emily; O'Keeffe, Dara A; Naughton, Peter A; Hill, Arnold D K; McDonnell, Ciaran O; Moneley, Daragh


    Complex endovascular skills are difficult to obtain in the clinical environment. Virtual reality (VR) simulator training is a valuable addition to current training curricula, but is there a benefit in the absence of expert trainers? Eighteen endovascular novices performed a renal artery angioplasty/stenting (RAS) on the Vascular Interventional Surgical Trainer simulator. They were randomized into three groups: Group A (n = 6, control), no performance feedback; Group B (n = 6, nonexpert feedback), feedback after every procedure from a nonexpert facilitator; and Group C (n = 6, expert feedback), feedback after every procedure from a consultant vascular surgeon. Each trainee completed RAS six times. Simulator-measured performance metrics included procedural and fluoroscopy time, contrast volume, accuracy of balloon placement, and handling errors. Clinical errors were also measured by blinded video assessment. Data were analyzed using SPSS version 15. A clear learning curve was observed across the six trials. There were no significant differences between the three groups for the general performance metrics, but Group C made fewer errors than Groups A (P = .009) or B (P = .004). Video-based error assessment showed that Groups B and C performed better than Group A (P = .002 and P = .000, respectively). VR simulator training for novices can significantly improve general performance in the absence of expert trainers. Procedure-specific qualitative metrics are improved with expert feedback, but nonexpert facilitators can also enhance the quality of training and may represent a valuable alternative to expert clinical faculty.

    An important problem in manned spaceflight is the nausea that typically appears during the first 3 days and then disappears after 5 days. Methods of detecting changes in electrophysiological signals are being studied in order to reduce susceptibility to space motion sickness through biofeedback training, and for the early detection of nausea during EVA. A simulator would allow subjects to control their body functions and to use biofeedback to control space motion sickness and stress.

  11. Comparison of results of virtual-reality simulator and training model for basic ureteroscopy training. (United States)

    Chou, David S; Abdelshehid, Corollos; Clayman, Ralph V; McDougall, Elspeth M


    The traditional method of acquiring surgical skills is by apprenticeship and involves an extensive period of training with patients. Model-based and virtual reality simulation is gaining interest as alternative training, allowing repetitive practice in a low-risk environment. The objective of this study was to determine if a materials, model-based training format and an interactive virtual-reality simulator could provide equivalent teaching of basic ureteroscopy skills to the inexperienced medical student. Sixteen first-year medical students received the same didactic session and video viewing on cystoscopy, guidewire access to the upper urinary tract, and ureteroscopy with intracorporeal laser lithotripsy and stone extraction by the same instructor. The participants were then randomized into two study groups: Group 1 was trained on the ureteroscopy training model (TMU) from Limbs & Things and Group 2 on the Simbionix UROMentor virtual-reality simulator (VRS) until the participants could perform the procedure independently. Two months later, the participants independently performed a ureteroscopic procedure on a pig kidney/ureter model and were graded from 1 to 5 on their ability to complete the steps of the procedure and the quality of their performance (handling of tissue, efficiency, instrument handling, knowledge of instruments, flow of operation, use of assistants, and knowledge of the specific procedure) for a possible total of 35 points. All participants were able to perform the steps of the procedure correctly. The TMU group and the VRS group received a mean of 22.9 +/- 4.8 and 23.6 +/- 5.4 points, respectively (P = 0.38) for their qualitative assessment. The medical students' skills and ability to perform a basic ureteroscopic stone-management procedure was independent of the training modality (VRS or TMU). Incorporating either of these devices into the preliminary training of urology residents may improve their initial clinical performance of these skills.

  12. Using simulation to train orthopaedic trainees in non-technical skills: A pilot study. (United States)

    Heaton, Samuel R; Little, Zoe; Akhtar, Kash; Ramachandran, Manoj; Lee, Joshua


    To enhance non-technical skills and to analyse participant's experience of a course tailored for orthopaedic surgeons. A Delphi technique was used to develop a course in human factors specific to orthopaedic residents. Twenty-six residents (six per course) participated in total with seven course facilitators all trained in Crisis Resource Management providing structured feedback. Six scenarios recreated challenging real-life situations using high-fidelity mannequins and simulated patients. Environments included a simulated operating suite, clinic room and ward setting. All were undertaken in a purpose built simulation suite utilising actors, mock operating rooms, mock clinical rooms and a high fidelity adult patient simulator organised through a simulation control room. Participants completed a 5-point Likert scale questionnaire (strongly disagree to strongly agree) before and after the course. This assessed their understanding of non-technical skills, scenario validity, relevance to orthopaedic training and predicted impact of the course on future practice. A course evaluation questionnaire was also completed to assess participants' feedback on the value and quality of the course itself. Twenty-six orthopaedic residents participated (24 male, 2 female; post-graduation 5-10 years), mean year of residency program 2.6 out of 6 years required in the United Kingdom. Pre-course questionnaires showed that while the majority of candidates recognised the importance of non-technical (NT) skills in orthopaedic training they demonstrated poor understanding of non-technical skills and their role. This improved significantly after the course (Likert score 3.0-4.2) and the perceived importance of these skills was reported as good or very good in 100%. The course was reported as enjoyable and provided an unthreatening learning environment with the candidates placing particular value on the learning opportunity provided by reflecting on their performance. All agreed that the

G.; Forrest, A. L.; Heaton, J.; Laval, B. E.; Arnold, R.; Nuytten, P.; Osinski, G.; Reay, M.; Reid, D.; Schulze-Makuch, D.; Shepard, R.; Slater, G. F.; Williams, D.


    Forthcoming human planetary exploration will require increased scientific return (both in real time and post-mission), longer surface stays, greater geographical coverage, longer and more frequent EVAs, and more operational complexities than during the Apollo missions. As such, there is a need to shift the nature of astronauts' scientific capabilities to something akin to an experienced terrestrial field scientist. To achieve this aim, the authors present a case that astronaut training should include an Apollo-style curriculum based on traditional field school experiences, as well as full immersion in field science programs. Herein we propose four Learning Design Principles (LDPs) focused on optimizing astronaut learning in field science settings. The LDPs are as follows: LDP#1: Provide multiple experiences: varied field science activities will hone astronauts' abilities to adapt to novel scientific opportunities LDP#2: Focus on the learner: fostering intrinsic motivation will orient astronauts towards continuous informal learning and a quest for mastery LDP#3: Provide a relevant experience - the field site: field sites that share features with future planetary missions will increase the likelihood that astronauts will successfully transfer learning LDP#4: Provide a social learning experience - the field science team and their activities: ensuring the field team includes members of varying levels of experience engaged in opportunities for discourse and joint problem solving will facilitate astronauts' abilities to think and perform like a field scientist. The proposed training program focuses on the intellectual and technical aspects of field science, as well as the cognitive manner in which field scientists experience, observe and synthesize their environment. The goal of the latter is to help astronauts develop the thought patterns and mechanics of an effective field scientist, thereby providing a broader base of experience and expertise than could be achieved

    This consensus group from the 2017 Academic Emergency Medicine Consensus Conference "Catalyzing System Change through Health Care Simulation: Systems, Competency, and Outcomes" held in Orlando, Florida, on May 16, 2017, focused on the use of human factors (HF) and simulation in the field of emergency medicine (EM). The HF discipline is often underutilized within EM but has significant potential in improving the interface between technologies and individuals in the field. The discussion explored the domain of HF, its benefits in medicine, how simulation can be a catalyst for HF work in EM, and how EM can collaborate with HF professionals to effect change. Implementing HF in EM through health care simulation will require a demonstration of clinical and safety outcomes, advocacy to stakeholders and administrators, and establishment of structured collaborations between HF professionals and EM, such as in this breakout group. © 2017 by the Society for Academic Emergency Medicine.

  20. Degrees of reality: airway anatomy of high-fidelity human patient simulators and airway trainers. (United States)

    Schebesta, Karl; Hüpfl, Michael; Rössler, Bernhard; Ringl, Helmut; Müller, Michael P; Kimberger, Oliver


    Human patient simulators and airway training manikins are widely used to train airway management skills to medical professionals. Furthermore, these patient simulators are employed as standardized "patients" to evaluate airway devices. However, little is known about how realistic these patient simulators and airway-training manikins really are. This trial aimed to evaluate the upper airway anatomy of four high-fidelity patient simulators and two airway trainers in comparison with actual patients by means of radiographic measurements. The volume of the pharyngeal airspace was the primary outcome parameter. Computed tomography scans of 20 adult trauma patients without head or neck injuries were compared with computed tomography scans of four high-fidelity patient simulators and two airway trainers. By using 14 predefined distances, two cross-sectional areas and three volume parameters of the upper airway, the manikins' similarity to a human patient was assessed. The pharyngeal airspace of all manikins differed significantly from the patients' pharyngeal airspace. The HPS Human Patient Simulator (METI®, Sarasota, FL) was the most realistic high-fidelity patient simulator (6/19 [32%] of all parameters were within the 95% CI of human airway measurements). The airway anatomy of four high-fidelity patient simulators and two airway trainers does not reflect the upper airway anatomy of actual patients. This finding may impact airway training and confound comparative airway device studies.

    To develop a robust psychomotor skills curriculum to teach pediatric airway foreign body retrieval and to assess the effect of this curriculum on residents' confidence in and ability to perform the complete task in an infant airway mannequin. Instructional course. Objective Structured Assessment of Technical Skills (OSATS). Surgical simulation laboratory. A half-day simulation-based course was developed to train otolaryngology residents in bronchoscopic foreign body retrieval. This complex psychomotor skill was deconstructed into subtasks. The following curricular learning objectives were presented and assessed: understanding of tracheobronchial anatomy, ability to adequately visualize the larynx with laryngoscopy, proficiency in rigid bronchoscopy, and familiarity with foreign body instrumentation. Residents were objectively evaluated on their ability to perform the complete task on a simulator before and after the course using an OSATS grading system. Confidence in successfully assembling the instruments and completing the task was assessed at these time periods. Seventeen otolaryngology residents completed the study. Confidence in assembling the instruments and in performing the complete task increased on average by 81% and 43%, respectively (P < .001). Using a 15-point OSATS grading system, the average score for the precourse was 7 and for the postcourse was 11.3 (P < .001). Simulation-based subtask training shows promise as an effective and reproducible method to teach the complex psychomotor task of airway foreign body retrieval. Completion of the curriculum led to a significant improvement in residents' confidence in and ability to perform bronchoscopic foreign body retrieval in an infant airway mannequin.

    González Gómez, J M; Chaves Vinagre, J; Ocete Hita, E; Calvo Macías, C


    Patient safety constitutes one of the main objectives in health care. Among other recommendations, such as the creation of training centres and the development of patient safety programmes, of great importance is the creation of training programmes for work teams using medical simulation. Medical simulation is defined as "a situation or environment created to allow persons to experience a representation of a real event for the purpose of practice, learning, evaluation or to understand systems or human actions". In this way, abilities can be acquired in serious and uncommon situations with no risk of harm to the patient. This study revises the origins of medical simulation and the different types of simulation are classified. The main simulators currently used in Pediatrics are presented, and the design of a simulation course applied to the training of pediatric emergencies is described, detailing all its different phases. In the first non face-to-face stage, a new concept in medical training known as e-learning is applied. In the second phase, clinical cases are carried out using robotic simulation; this is followed by a debriefing session, which is a key element for acquiring abilities and skills. Lastly, the follow-up phase allows the student to connect with the teachers to consolidate the concepts acquired during the in-person phase. In this model, the aim is to improve scientific-technical abilities in addition to a series of related abilities such as controlling crisis situations, correct leadership of work teams, distribution of tasks, communication among the team members, etc., all of these within the present concept of excellence in care and medical professionalism.

  6. Adherence and perceptions regarding simulation training in undergraduate health Sciences

    Directory of Open Access Journals (Sweden)

    Fernando Perpétuo Elias

    Full Text Available BACKGROUND: Simulation techniques are spreading rapidly in medicine. Suc h resources are increasingly concentrated in Simulation Laboratories. The MSRP-USP is structuring such a laboratory and is interested in the prevalence of individual initiatives that could be centralized there. The MSRP-USP currently has five full-curriculum courses in the health sciences: Medicine, Speech Therapy, Physical Therapy, Nutrition, and Occupational Therapy, all consisting of core disciplines. GOAL: To determine the prevalence of simulation techniques in the regular courses at MSRP-USP. METHODS: Coordinators of disciplines in the various courses were interviewed using a specifically designed semi-structured questionnaire, and all the collected data were stored in a dedicated database. The disciplines were grouped according to whether they used (GI or did not use (GII simulation resources. RESULTS AND DISCUSSION: 256 disciplines were analyzed, of which only 18.3% used simulation techniques, varying according to course: Medicine (24.7.3%, Occupational Therapy (23.0%, Nutrition (15.9%, Physical Therapy (9.8%, and Speech Therapy (9.1%. Computer simulation programs predominated (42.5% in all five courses. The resources were provided mainly by MSRP-USP (56.3%, with additional funding coming from other sources based on individual initiatives. The same pattern was observed for maintenance. There was great interest in centralizing the resources in the new Simulation Laboratory in order to facilitate maintenance, but there was concern about training and access to the material. CONCLUSIONS: 1 The MSRP-USP simulation resources show low complexity and are mainly limited to computer programs; 2 Use of simulation varies according to course, and is most prevalent in Medicine; 3 Resources are scattered across several locations, and their acquisition and maintenance depend on individual initiatives rather than central coordination or curricular guidelines

    Full Text Available This work addresses the design of an active multi-link micro-catheter actuated by Shape Memory Alloy (SMA micro actuators. This may be a response to one medical major demand on such devices, which will be useful for surgical explorations and interventions. In this paper, we focus on a training and design simulator dedicated to such catheters. This simulator is based on an original simulation platform (OpenMASK. The catheter is a robotic system, which is evaluated by a dynamical simulation addressing a navigation task in its environment. The design of the prototype and its mechanical model are presented. We develop an interaction model for contact. This model uses a real medical database for which distance cartography is proposed. Then we focus on an autonomous control model based on a multi-agent approach and including the behaviour description of the SMA actuators. Results of mechanical simulations including interaction with the ducts are presented. Furthermore, the interest of such a simulator is presented by applying virtual prototyping techniques for the design optimization. This optimization process is achieved by using genetic algorithms at different stages with respect to the specified task.

  8. Temporal bone dissection simulator for training pediatric otolaryngology surgeons (United States)

    Tabrizi, Pooneh R.; Sang, Hongqiang; Talari, Hadi F.; Preciado, Diego; Monfaredi, Reza; Reilly, Brian; Arikatla, Sreekanth; Enquobahrie, Andinet; Cleary, Kevin


    Cochlear implantation is the standard of care for infants born with severe hearing loss. Current guidelines approve the surgical placement of implants as early as 12 months of age. Implantation at a younger age poses a greater surgical challenge since the underdeveloped mastoid tip, along with thin calvarial bone, creates less room for surgical navigation and can result in increased surgical risk. We have been developing a temporal bone dissection simulator based on actual clinical cases for training otolaryngology fellows in this delicate procedure. The simulator system is based on pre-procedure CT (Computed Tomography) images from pediatric infant cases (<12 months old) at our hospital. The simulator includes: (1) simulation engine to provide the virtual reality of the temporal bone surgery environment, (2) a newly developed haptic interface for holding the surgical drill, (3) an Oculus Rift to provide a microscopic-like view of the temporal bone surgery, and (4) user interface to interact with the simulator through the Oculus Rift and the haptic device. To evaluate the system, we have collected 10 representative CT data sets and segmented the key structures: cochlea, round window, facial nerve, and ossicles. The simulator will present these key structures to the user and warn the user if needed by continuously calculating the distances between the tip of surgical drill and the key structures.

  12. Operational NDT simulator, towards human factors integration in simulated probability of detection (United States)

    Rodat, Damien; Guibert, Frank; Dominguez, Nicolas; Calmon, Pierre


    In the aeronautic industry, the performance demonstration of Non-Destructive Testing (NDT) procedures relies on Probability Of Detection (POD) analyses. This statistical approach measures the ability of the procedure to detect a flaw with regard to one of its characteristic dimensions. The inspection chain is evaluated as a whole, including equipment configuration, probe effciency but also operator manipulations. Traditionally, a POD study requires an expensive campaign during which several operators apply the procedure on a large set of representative samples. Recently, new perspectives for the POD estimation have been introduced using NDT simulation to generate data. However, these approaches do not offer straightforward solutions to take the operator into account. The simulation of human factors, including cognitive aspects, often raises questions. To address these diffculties, we propose a concept of operational NDT simulator [1]. This work presents the first steps in the implementation of such simulator for ultrasound phased array inspection of composite parts containing Flat Bottom Holes (FBHs). The final system will look like a classical ultrasound testing equipment with a single exception: the displayed signals will be synthesized. Our hardware (ultrasound acquisition card, 3D position tracker) and software (position analysis, inspection scenario, synchronization, simulations) environments are developed as a bench to test the meta-modeling techniques able to provide fast-simulated realistic ultra-sound signals. The results presented here are obtained by on-the-fly merging of real and simulated signals. They confirm the feasibility of our approach: the replacement of real signals by purely simulated ones has been unnoticed by operators. We believe this simulator is a great prospect for POD evaluation including human factors, and may also find applications for training or procedure set-up.

  13. A comparison of live tissue training and high-fidelity patient simulator: A pilot study in battlefield trauma training. (United States)

    Trauma procedural and management skills are often learned on live tissue. However, there is increasing pressure to use simulators because their fidelity improves and as ethical concerns increase. We randomized military medical technicians (medics) to training on either simulators or live tissue to learn combat casualty care skills to determine if the choice of modality was associated with differences in skill uptake. Twenty medics were randomized to trauma training using either simulators or live tissue. Medics were trained to perform five combat casualty care tasks (surgical airway, needle decompression, tourniquet application, wound packing, and intraosseous line insertion). We measured skill uptake using a structured assessment tool. The medics also completed exit questionnaires and interviews to determine which modality they preferred. We found no difference between groups trained with live tissue versus simulators in how they completed each combat casualty care skill. However, we did find that the modality of assessment affected the assessment score. Finally, we found that medics preferred trauma training on live tissue because of the fidelity of tissue handling in live tissue models. However, they also felt that training on simulators also provided additional training value. We found no difference in performance between medics trained on simulators versus live tissue models. Even so, medics preferred live tissue training over simulation. However, more studies are required, and future studies need to address the measurement bias of measuring outcomes in the same model on which the study participants are trained.

  14. Validation of a realistic simulator for veterinary gastrointestinal endoscopy training. (United States)

    Usón-Gargallo, Jesús; Usón-Casaús, Jesús M; Pérez-Merino, Eva M; Soria-Gálvez, Federico; Morcillo, Esther; Enciso, Silvia; Sánchez-Margallo, Francisco M


    This article reports on the face, content, and construct validity of a new realistic composite simulator (Simuldog) used to provide training in canine gastrointestinal flexible endoscopy. The basic endoscopic procedures performed on the simulator were esophagogastroduodenoscopy (EGD), gastric biopsy (GB), and gastric foreign body removal (FBR). Construct validity was assessed by comparing the performance of novices (final-year veterinary students and recent graduates without endoscopic experience, n=30) versus experienced subjects (doctors in veterinary medicine who had performed more than 50 clinical upper gastrointestinal endoscopic procedures as a surgeon, n=15). Tasks were scored based on completion time, and specific rating scales were developed to assess performance. Internal consistency and inter-rater agreement were assessed. Face and content validity were determined using a 5-point Likert-type scale questionnaire. The novices needed considerably more time than the experts to perform EGD, GB, and FBR, and their performance scores were significantly lower (pinternal validity of the rating scales were good. Face validity was excellent, and both groups agreed that the endoscopy scenarios were very realistic. The experts highly valued the usefulness of Simuldog for veterinary training and as a tool for assessing endoscopic skills. Simuldog is the first validated model specifically developed to be used as a training tool for endoscopy techniques in small animals.

  15. Biosimmer: A Virtual Reality Simulator for Training First Responders in a BW Scenario

    Energy Technology Data Exchange (ETDEWEB)

    Shawver, D.M.; Sobel, A.L.; Stansfield, S.A.


    BioSimMER (Bioterrorism Simulated Medical Emergency Response) is a Virtual Reality-based mission rehearsal and training environment. BioSimMER employs contingency-oriented, multiple-path algorithms and MOESINIOPS focused on real-world operations. BioSimMER is network-based and immerses multiple trainees in a high resolution synthetic environment, including virtual casualties and instruments that they may interact with and manipulate. Trainees are represented as individuals by virtual human Avatars. The simulation consists of several components: virtual casualties dynamically manifest the symptoms of their injuries and respond to the intervention of the trainees. Agent transport analysis is used to simulate casualty exposures and to drive the responses of simulated sensors/detectors. The selected prototype scenario is representative of combined injuries anticipated in BW operations.

  16. Mobile emergency simulation training for rural health providers. (United States)

    Martin, Douglas; Bekiaris, Brent; Hansen, Gregory


    Mobile emergency simulation offers innovative continuing medical educational support to regions that may lack access to such opportunities. Furthermore, satisfaction is a critical element for active learning. Together, the authors evaluated Canadian rural healthcare providers' satisfaction from high fidelity emergency simulation training using a modified motorhome as a mobile education unit (MEU). Over a 5-month period, data was collected during 14 educational sessions in nine different southern Manitoban communities. Groups of up to five rural healthcare providers managed emergency simulation cases including polytrauma, severe sepsis, and inferior myocardial infarction with right ventricular involvement, followed by a debrief. Participants anonymously completed a feedback form that contained 11 questions on a five-point Likert scale and six short-answer questions. Data from 131 respondents were analyzed, for a response rate of 75.6%. Respondents included nurses (27.5%), medical residents (26.7%), medical first responders (16.0%), and physicians (12.2%). The median response was 5 for overall quality of learning, development of clinical reasoning skills and decision-making ability, recognition of patient deterioration, and self-reflection. The post-simulation debrief median response was also 5 for summarizing important issues, constructive criticism, and feedback to learn. Respondents also reported that the MEU provided a believable working environment (87.0%, n=114), they had limited or no previous access to high fidelity mannequins (82.7%, n=107), and they had no specific training in crisis resource management or were unfamiliar with the term (92%, n=118). A high level of satisfaction was reported in rural health providers with mobile emergency simulation. Access to and experience with high fidelity mannequins was limited, suggesting areas for potential educational growth.

  19. Mechanisms for training security inspectors to enhance human performance

    Energy Technology Data Exchange (ETDEWEB)

    Burkhalter, H.E.; Sessions, J.C.


    The Department of Energy (DOE) has established qualification standards for protective force personnel employed at nuclear facilities (10 CFR Part 1046 (Federal Register)). Training mechanisms used at Los Alamos to enhance human performance in meeting DOE standards include, but are not limited to, the following: for cardio-respiratory training, they utilize distance running, interval training, sprint training, pacing, indoor aerobics and circuit training; for muscular strength, free weights, weight machines, light hand weights, grip strength conditioners, and calistenics are employed; for muscular endurance, participants do high repetitions (15 - 40) using dumbbells, flex weights, resistive rubber bands, benches, and calisthenics; for flexibility, each training session devotes specific times to stretch the muscles involved for a particular activity. These training mechanisms with specific protocols can enhance human performance.

  20. Simulation Based Training Improves Airway Management for Helicopter EMS Teams (United States)

    Dhindsa, Harinder S.; Reid, Renee; Murray, David; Lovelady, James; Powell, Katie; Sayles, Jeff; Stevenson, Christopher; Baker, Kathy; Solada, Brian; Carroll, Scott; hide


    The use of paralytic medications in the performance of RSI intubation is a high risk intervention used by many HEMS crews. There is no margin for error in RSI intubation as the results can be fatal. Operating room access for airway management training has become more difficult, and is not representative of the environment in which HEMS crews typically function. LifeEvac of Virginia designed and implemented an SST airway management program to provide a realistic, consistent training platform. The dynamic program incorporates standardized scenarios, and real life challenging cases that this and other programs have encountered. SST is done in a variety of settings including the helicopter, back of ambulances, staged car crashes and simulation centers. The result has been the indoctrination of a well defined, consistent approach to every airway management intervention. The SST program facillitates enhancement of technical skills. as well as team dynamics and communication.

  1. Simulation Training for the Office-Based Anesthesia Team. (United States)

    Ritt, Richard M; Bennett, Jeffrey D; Todd, David W


    An OMS office is a complex environment. Within such an environment, a diverse scope of complex surgical procedures is performed with different levels of anesthesia, ranging from local anesthesia to general anesthesia, on patients with varying comorbidities. Optimal patient outcomes require a functional surgical and anesthetic team, who are familiar with both standard operational principles and emergency recognition and management. Offices with high volume and time pressure add further stress and potential risk to the office environment. Creating and maintaining a functional surgical and anesthetic team that is competent with a culture of patient safety and risk reduction is a significant challenge that requires time, commitment, planning, and dedication. This article focuses on the role of simulation training in office training and preparation. Copyright © 2017 Elsevier Inc. All rights reserved.

  3. Robotic Surgery Simulator: Elements to Build a Training Program. (United States)

    Tillou, Xavier; Collon, Sylvie; Martin-Francois, Sandrine; Doerfler, Arnaud


    Face, content, and construct validity of robotic surgery simulators were confirmed in the literature by several studies, but elements to build a training program are still lacking. The aim of our study was to validate a progressive training program and to assess according to prior surgical experience the amount of training needed with a robotic simulator to complete the program. Exercises using the Da Vinci Skill Simulator were chosen to ensure progressive learning. A new exercise could only be started if a minimal score of 80% was achieved in the prior one. The number of repetitions to achieve an exercise was not limited. We devised a "performance index" by calculating the ratio of the sum of scores for each exercise over the number of repetitions needed to complete the exercise with at least an 80% score. The study took place at the François Baclesse Cancer Center. Participants all work at the primary care university Hospital located next to the cancer center. A total of 32 surgeons participated in the study- 2 experienced surgeons, 8 junior and 8 senior residents in surgery, 6 registrars, and 6 attending surgeons. There was no difference between junior and senior residents, whereas the registrars had better results (p surgery console in a specific and progressive order enables rapid progress. The level of prior experience in laparoscopic surgery affects outcomes. More advanced laparoscopic expertise seems to slow down learning, surgeons having to "unlearn" to acquire a new technique.

  6. Virtual simulation-enhanced triage training for Iraqi medical personnel. (United States)

    Kizakevich, Paul N; Culwell, Andrew; Furberg, Robert; Gemeinhardt, Don; Grantlin, Susan; Hubal, Robert; Stafford, Allison; Dombroski, R Todd


    Triage, establishing the priority of care among casualties in disaster management, is generally practiced using constructive tabletop or live exercises. Actual disasters involving multiple casualties occur rarely, offering little opportunity for gaining experience and competency assessment. When they do occur, response needs to be rapid and well-learned. In the Iraqi medical education environment where the need for triage is immediate, but the ability to stage practice is nearly impossible, blending didactic learning with simulation-based triage offers an alternative training methodology.

  7. Assessment of Simulated Emergency Scenarios: Are Trained Observers Necessary? (United States)

    Noveanu, Juliane; Amsler, Felix; Ummenhofer, Wolfgang; von Wyl, Thomas; Zuercher, Mathias


    Simulation-based medical training is associated with superior educational outcomes and improved cost efficiency. Self- and peer-assessment may be a cost-effective and flexible alternative to expert-led assessment. We compared accuracy of self- and peer-assessment of untrained raters using basic evaluation tools to expert assessment using advanced validation tools including validated questionnaires and post hoc video-based analysis. Twenty-eight simulated emergency airway management scenarios were observed and video-recorded for further assessment. Participants consisted of 28 emergency physicians who were involved in four different airway management scenarios with different roles: One scenario as a team leader, one as an assisting team member, and two as an observer. Non-technical skills (NTS) and technical skills (TS) were analyzed by three independent groups: 1) the performing team (PT) consisted of the two emergency physicians acting either in the role of team leader or team member (self-assessment); 2) the observing team (OT), consisted of two of the participating emergency physicians not involved in the current clinical scenario (peer-assessment) and assessment occurred during (OT) or directly after (PT) the simulation without prior specific interpretational training but using standardized questionnaires; and 3) the expert team (ET) consisted of two specifically trained external observers (one psychologist and one emergency physician) using video-assisted objective assessment combined with standardized questionnaires. Intragroup reliability demonstrated by intra-class correlation (ICC) was moderate to good for TS (ICC 0.42(*)) and NTS (ICC 0.55(*)) in PT and moderate to good for TS (ICC 0.41(*)) or poor for NTS (ICC 0.27) in OT. ET showed an excellent intragroup reliability for both TS (ICC 0.78(*)) and NTS (ICC 0.81(*)). Interrater reliability was significantly different between ET and PT and between ET and OT for both TS and NTS. There was no difference

    Full Text Available Flights conditions of combat aircrafts subject to dynamic changes in variable environment, where properly trained and skilled pilots, capable of perceiving stimuli from outside, play key roles in the decision-making process. The study discloses analyses that have been completed on grounds of survey results carried out for a specific population of cadets and pilots that had practiced on flight simulators. The surveys consisted in measurements of the human response time to artificially arranged emergency circumstances with counting of misbehaviour and errors. Then, upon analysis of correlation between skill features demonstrated by pilot candidates (cadets and trained pilots and with consideration to functions of probability distribution of these features it is possible to estimate expected results that should be achieved by cadets for specific exercises to assess the training system as efficient and suitable to provide intended results when real tasks are assigned to trainees flying eventual aircrafts.

    Joyce, David L; Dhillon, Tanvir S; Caffarelli, Anthony D; Joyce, Daniel D; Tsirigotis, Dimitrios N; Burdon, Thomas A; Fann, James I


    Limited exposure and visualization and technical complexity have affected resident training in mitral valve surgery. We propose simulation-based learning to improve skill acquisition in mitral valve surgery. After reviewing instructional video recordings of mitral annuloplasty in porcine and plastic models, 11 residents (6 integrated and 5 traditional) performed porcine model mitral annuloplasty. Video-recorded performance was reviewed by attending surgeon providing audio formative feedback superimposed on video recordings; recordings were returned to residents for review. After 3-week practice with plastic model, residents repeated porcine model mitral annuloplasty. Performance assessments initially (prefeedback) and at 3 weeks (postfeedback) were based on review of video recordings on 5-point rating scale (5, good; 3, average; 1, poor) of 11 components. Ratings were averaged for composite score. Time to completion improved from mean 31 ± 9 minutes to 25 ± 6 minutes after 3-week practice (P = .03). At 3 weeks, improvement in technical components was achieved by all residents, with prefeedback scores varying from 2.4 ± 0.6 for needle angles to 3.0 ± 0.5 for depth of bites and postfeedback scores of 3.1 ± 0.8 for tissue handling to 3.6 ± 0.8 for suture management and tension (P ≤ .001). Interrater reliability was greater than 0.8. In this sample, composite scores of first-year integrated and traditional residents were lower than those of senior level residents; comparatively, third-year integrated residents demonstrated good technical proficiency. Simulation-based learning with formative feedback results in overall improved performance of simulated mitral annuloplasty. In complex surgical procedures, simulation may provide necessary early graduated training and practice. Importantly, a "passing" grade can be established for proficiency-based advancement.

    To establish the effect of self-directed virtual reality (VR) simulation training on cadaveric dissection training performance in mastoidectomy and the transferability of skills acquired in VR simulation training to the cadaveric dissection training setting. Prospective study. Two cohorts of 20 novice otorhinolaryngology residents received either self-directed VR simulation training before cadaveric dissection training or vice versa. Cadaveric and VR simulation performances were assessed using final-product analysis with three blinded expert raters. The group receiving VR simulation training before cadaveric dissection had a mean final-product score of 14.9 (95 % confidence interval [CI] [12.9-16.9]) compared with 9.8 (95% CI [8.4-11.1]) in the group not receiving VR simulation training before cadaveric dissection. This 52% increase in performance was statistically significantly (P training was effective in increasing cadaveric dissection mastoidectomy performance and suggests that mastoidectomy skills are transferable from VR simulation to the traditional dissection setting. Virtual reality simulation training can therefore be employed to optimize training, and can spare the use of donated material and instructional resources for more advanced training after basic competencies have been acquired in the VR simulation environment.

  15. Cognitive Load in Mastoidectomy Skills Training: Virtual Reality Simulation and Traditional Dissection Compared. (United States)

    Andersen, Steven Arild Wuyts; Mikkelsen, Peter Trier; Konge, Lars; Cayé-Thomasen, Per; Sørensen, Mads Sølvsten


    The cognitive load (CL) theoretical framework suggests that working memory is limited, which has implications for learning and skills acquisition. Complex learning situations such as surgical skills training can potentially induce a cognitive overload, inhibiting learning. This study aims to compare CL in traditional cadaveric dissection training and virtual reality (VR) simulation training of mastoidectomy. A prospective, crossover study. Participants performed cadaveric dissection before VR simulation of the procedure or vice versa. CL was estimated by secondary-task reaction time testing at baseline and during the procedure in both training modalities. The national Danish temporal bone course. A total of 40 novice otorhinolaryngology residents. Reaction time was increased by 20% in VR simulation training and 55% in cadaveric dissection training of mastoidectomy compared with baseline measurements. Traditional dissection training increased CL significantly more than VR simulation training (p < 0.001). VR simulation training imposed a lower CL than traditional cadaveric dissection training of mastoidectomy. Learning complex surgical skills can be a challenge for the novice and mastoidectomy skills training could potentially be optimized by employing VR simulation training first because of the lower CL. Traditional dissection training could then be used to supplement skills training after basic competencies have been acquired in the VR simulation.

  16. A novel anatomical ceramic root canal simulator for endodontic training. (United States)

    Robberecht, L; Chai, F; Dehurtevent, M; Marchandise, P; Bécavin, T; Hornez, J-C; Deveaux, E


    Endodontic therapy is often complicated and technically demanding. The aim of this study was to develop a reproducible biomimetic root canal model for pre-clinical and postgraduate endodontic training. A specific ceramic shaping technique (3D printing and slip casting of a root canal mould) was developed to reproduce canal systems with the desired shape and complexity using a microporous hydroxyapatite (HAp)-based matrix. The microstructural morphology, pore size and porosity, as well as the Vickers microhardness of the ceramic simulators (CS) were assessed and were compared with natural dentin and commercial resin blocks. The reproducibility of the root canal shapes was assessed using the Dice-Sørensen similarity index. Endodontic treatments, from refitting the access cavity to obturation, were performed on the CS. Each step was controlled by radiography. Many properties of the CS were similar to those of natural dental roots, including the mineral component (HAp), porosity (20%, porous CS), pore size (3.4 ± 2.6 μm) and hardness (120.3 ± 18.4 HV). We showed that it is possible to reproduce the radio-opacity of a tooth and variations in root canal morphology. The endodontic treatments confirmed that the CS provided good tactile sensation during instrumentation and displayed suitable radiological behaviour. This novel anatomic root canal simulator is well suited for training undergraduate and postgraduate students in endodontic procedures. © 2016 John Wiley & Sons A/S.

  17. Simulation of developing human neuronal cell networks. (United States)

    Lenk, Kerstin; Priwitzer, Barbara; Ylä-Outinen, Laura; Tietz, Lukas H B; Narkilahti, Susanna; Hyttinen, Jari A K


    Microelectrode array (MEA) is a widely used technique to study for example the functional properties of neuronal networks derived from human embryonic stem cells (hESC-NN). With hESC-NN, we can investigate the earliest developmental stages of neuronal network formation in the human brain. In this paper, we propose an in silico model of maturating hESC-NNs based on a phenomenological model called INEX. We focus on simulations of the development of bursts in hESC-NNs, which are the main feature of neuronal activation patterns. The model was developed with data from developing hESC-NN recordings on MEAs which showed increase in the neuronal activity during the investigated six measurement time points in the experimental and simulated data. Our simulations suggest that the maturation process of hESC-NN, resulting in the formation of bursts, can be explained by the development of synapses. Moreover, spike and burst rate both decreased at the last measurement time point suggesting a pruning of synapses as the weak ones are removed. To conclude, our model reflects the assumption that the interaction between excitatory and inhibitory neurons during the maturation of a neuronal network and the spontaneous emergence of bursts are due to increased connectivity caused by the forming of new synapses.

    Full Text Available For decades the issue of training through simulation has been discussed and studied to show its value and importance in fighter pilot training programs. Besides the fact that simulators are less expensive than a real airplane, and eliminate the operational risks that are present in a real flight they bring a significant contribution to the pilot training by their fidelity and realism that they show in such scenarios as in the reality. To measure the efficiency of training transfer from simulator to the aircraft, performance indicators were defined. The purpose of this article is to define these performance indicators and measurement of training transfer within the flight simulator involvement.

  2. Kinematic Skeleton Based Control of a Virtual Simulator for Military Training

    Directory of Open Access Journals (Sweden)

    Soyeon Lee


    Full Text Available Virtual simulation technology has been considered as a highly efficient and cost-effective solution for a soldier training system, and evolved into diverse combinations of hardware and software. To maximize the virtual reality effect within a restricted space, a locomotion interface such as an omni-directional treadmill is introduced as a major component of a virtual simulator, therefore real time interaction between human and the virtual simulator becomes very important. Displacement and heading changes of the trainee are crucial information to control the virtual simulator when we implement highly reactive motion control for the omni-directional treadmill and interaction control of the virtual contents. This paper proposes a control parameter estimation algorithm for the virtual training simulator by using two types of motion capture sensors and presents the experimental results. Kinematic joint positions are analyzed to estimate the trainee’s location and velocity for feedback and feedforward control of the omni-directional treadmill. The accuracy of two approaches is evaluated by comparing with the reference system, which gives a ground truth value.

    Waller, Edward; Bereznai, George; Shaw, John; Chaput, Joseph; Lafortune, Jean-Francois

    Training offsite emergency response personnel basic awareness of onsite control room operations during nuclear power plant emergency conditions was the primary objective of a week-long workshop conducted on a CANDU® virtual nuclear reactor simulator available at the University of Ontario Institute of Technology, Oshawa, Canada. The workshop was designed to examine both normal and abnormal reactor operating conditions, and to observe the conditions in the control room that may have impact on the subsequent offsite emergency response. The workshop was attended by participants from a number of countries encompassing diverse job functions related to nuclear emergency response. Objectives of the workshop were to provide opportunities for participants to act in the roles of control room personnel under different reactor operating scenarios, providing a unique experience for participants to interact with the simulator in real-time, and providing increased awareness of control room operations during accident conditions. The ability to "pause" the simulator during exercises allowed the instructors to evaluate and critique the performance of participants, and to provide context with respect to potential offsite emergency actions. Feedback from the participants highlighted (i) advantages of observing and participating "hands-on" with operational exercises, (ii) their general unfamiliarity with control room operational procedures and arrangements prior to the workshop, (iii) awareness of the vast quantity of detailed control room procedures for both normal and transient conditions, and (iv) appreciation of the increased workload for the operators in the control room during a transient from normal operations. Based upon participant feedback, it was determined that the objectives of the training had been met, and that future workshops should be conducted.

    Rice, Yvonne; DeLetter, Mary; Fryman, Lisa; Parrish, Evelyn; Velotta, Cathie; Talley, Cynthia


    Care of the trauma patient requires a well-coordinated intensive effort during the golden hour to optimize survival. We hypothesized that this program would improve knowledge, satisfaction, self-confidence, and simulated team performance. A pre-, post-test design with N = 7 BSN nurses, 21 years of age, less than 2 years of intensive care unit and nursing experience. Trauma intensive care unit, single-center academic Level 1 trauma center. Improvement was shown in perception of team structure (paired t test 13.71-12.57; p = .0001) and communication (paired t test 14.85-12.14; p = .009). Improvement was shown in observed situation monitoring (paired t test 17.42-25.28; p = .000), mutual support (paired t test 12.57-18.57; p = .000), and communication (paired t test 15.42-25.00; p = .001). A decrease was shown in attitudes of mutual support (paired t test 25.85-19.71; p = .04) and communication (paired t test 26.14-23.00; p = .001). Mean satisfaction scores were 21.5 of a possible 25 points. Mean self-confidence scores were 38.83 out of a possible 40 points. Simulation-based team training improved teamwork attitudes, perceptions, and performance. Team communication demonstrated significant improvement in 2 of the 3 instruments. Most participants agreed or strongly agreed that they were satisfied with simulation and had gained self-confidence.

  8. Simulation and training of lumbar punctures using haptic volume rendering and a 6DOF haptic device (United States)

    Färber, Matthias; Heller, Julika; Handels, Heinz


    The lumbar puncture is performed by inserting a needle into the spinal chord of the patient to inject medicaments or to extract liquor. The training of this procedure is usually done on the patient guided by experienced supervisors. A virtual reality lumbar puncture simulator has been developed in order to minimize the training costs and the patient's risk. We use a haptic device with six degrees of freedom (6DOF) to feedback forces that resist needle insertion and rotation. An improved haptic volume rendering approach is used to calculate the forces. This approach makes use of label data of relevant structures like skin, bone, muscles or fat and original CT data that contributes information about image structures that can not be segmented. A real-time 3D visualization with optional stereo view shows the punctured region. 2D visualizations of orthogonal slices enable a detailed impression of the anatomical context. The input data consisting of CT and label data and surface models of relevant structures is defined in an XML file together with haptic rendering and visualization parameters. In a first evaluation the visible human male data has been used to generate a virtual training body. Several users with different medical experience tested the lumbar puncture trainer. The simulator gives a good haptic and visual impression of the needle insertion and the haptic volume rendering technique enables the feeling of unsegmented structures. Especially, the restriction of transversal needle movement together with rotation constraints enabled by the 6DOF device facilitate a realistic puncture simulation.

    Zhang, Ming-ya; Cheng, Xin; Xu, An-ding; Luo, Liang-ping; Yang, Xuesong


    Background Modern medical education promotes medical students’ clinical operating capacity rather than the mastery of theoretical knowledge. To accomplish this objective, clinical skill training using various simulations was introduced into medical education to cultivate creativity and develop the practical ability of students. However, quantitative analysis of the efficiency of clinical skill training with simulations is lacking. Methods In the present study, we compared the mean scores of medical students (Jinan University) who graduated in 2013 and 2014 on 16 stations between traditional training (control) and simulative training groups. In addition, in a clinical skill competition, the objective structured clinical examination (OSCE) scores of participating medical students trained using traditional and simulative training were compared. The data were statistically analyzed and qualitatively described. Results The results revealed that simulative training could significantly enhance the graduate score of medical students compared with the control. The OSCE scores of participating medical students in the clinical skill competition, trained using simulations, were dramatically higher than those of students trained through traditional methods, and we also observed that the OSCE marks were significantly increased for the same participant after simulative training for the clinical skill competition. Conclusions Taken together, these data indicate that clinical skill training with a variety of simulations could substantially promote the clinical performance of medical students and optimize the resources used for medical education, although a precise analysis of each specialization is needed in the future.

  11. Beyond crisis resource management: new frontiers in human factors training for acute care medicine. (United States)

    Petrosoniak, Andrew; Hicks, Christopher M


    Error is ubiquitous in medicine, particularly during critical events and resuscitation. A significant proportion of adverse events can be attributed to inadequate team-based skills such as communication, leadership, situation awareness and resource utilization. Aviation-based crisis resource management (CRM) training using high-fidelity simulation has been proposed as a strategy to improve team behaviours. This review will address key considerations in CRM training and outline recommendations for the future of human factors education in healthcare. A critical examination of the current literature yields several important considerations to guide the development and implementation of effective simulation-based CRM training. These include defining a priori domain-specific objectives, creating an immersive environment that encourages deliberate practice and transfer-appropriate processing, and the importance of effective team debriefing. Building on research from high-risk industry, we suggest that traditional CRM training may be augmented with new training techniques that promote the development of shared mental models for team and task processes, address the effect of acute stress on team performance, and integrate strategies to improve clinical reasoning and the detection of cognitive errors. The evolution of CRM training involves a 'Triple Threat' approach that integrates mental model theory for team and task processes, training for stressful situations and metacognition and error theory towards a more comprehensive training paradigm, with roots in high-risk industry and cognitive psychology. Further research is required to evaluate the impact of this approach on patient-oriented outcomes.

    Full Text Available Background: Age-related cognitive decline is often associated with unsafe driving behavior. We hypothesized that 10 active training sessions in a driving simulator increase cognitive and on-road driving performance. In addition, driving simulator training should outperform cognitive training.Methods: Ninety-one healthy active drivers (62 – 87 years were randomly assigned to either (1 a driving simulator training group, (2 an attention training group (vigilance and selective attention, or (3 a control group. The main outcome variables were on-road driving and cognitive performance. Seventy-seven participants (85% completed the training and were included in the analyses. Training gains were analyzed using a multiple regression analysis with planned comparisons.Results: The driving simulator training group showed an improvement in on-road driving performance compared to the attention training group. In addition, both training groups increased cognitive performance compared to the control group. Conclusion: Driving simulator training offers the potential to enhance driving skills in older drivers. Compared to the attention training, the simulator training seems to be a more powerful program for increasing older drivers’ safety on the road.

    Age-related cognitive decline is often associated with unsafe driving behavior. We hypothesized that 10 active training sessions in a driving simulator increase cognitive and on-road driving performance. In addition, driving simulator training should outperform cognitive training. Ninety-one healthy active drivers (62-87 years) were randomly assigned to one of three groups: (1) a driving simulator training group, (2) an attention training group (vigilance and selective attention), or (3) a control group. The main outcome variables were on-road driving and cognitive performance. Seventy-seven participants (85%) completed the training and were included in the analyses. Training gains were analyzed using a multiple regression analysis with planned orthogonal comparisons. The driving simulator-training group showed an improvement in on-road driving performance compared to the attention-training group. In addition, both training groups increased cognitive performance compared to the control group. Driving simulator training offers the potential to enhance driving skills in older drivers. Compared to the attention training, the simulator training seems to be a more powerful program for increasing older drivers' safety on the road.

  18. A review of virtual reality based training simulators for orthopaedic surgery. (United States)

    Vaughan, Neil; Dubey, Venketesh N; Wainwright, Thomas W; Middleton, Robert G


    This review presents current virtual reality based training simulators for hip, knee and other orthopaedic surgery, including elective and trauma surgical procedures. There have not been any reviews focussing on hip and knee orthopaedic simulators. A comparison of existing simulator features is provided to identify what is missing and what is required to improve upon current simulators. In total 11 hip replacements pre-operative planning tools were analysed, plus 9 hip trauma fracture training simulators. Additionally 9 knee arthroscopy simulators and 8 other orthopaedic simulators were included for comparison. The findings are that for orthopaedic surgery simulators in general, there is increasing use of patient-specific virtual models which reduce the learning curve. Modelling is also being used for patient-specific implant design and manufacture. Simulators are being increasingly validated for assessment as well as training. There are very few training simulators available for hip replacement, yet more advanced virtual reality is being used for other procedures such as hip trauma and drilling. Training simulators for hip replacement and orthopaedic surgery in general lag behind other surgical procedures for which virtual reality has become more common. Further developments are required to bring hip replacement training simulation up to date with other procedures. This suggests there is a gap in the market for a new high fidelity hip replacement and resurfacing training simulator. Copyright © 2015 IPEM. Published by Elsevier Ltd. All rights reserved.

  19. Musical training induces functional plasticity in human hippocampus. (United States)

    Herdener, Marcus; Esposito, Fabrizio; di Salle, Francesco; Boller, Christian; Hilti, Caroline C; Habermeyer, Benedikt; Scheffler, Klaus; Wetzel, Stephan; Seifritz, Erich; Cattapan-Ludewig, Katja


    Training can change the functional and structural organization of the brain, and animal models demonstrate that the hippocampus formation is particularly susceptible to training-related neuroplasticity. In humans, however, direct evidence for functional plasticity of the adult hippocampus induced by training is still missing. Here, we used musicians' brains as a model to test for plastic capabilities of the adult human hippocampus. By using functional magnetic resonance imaging optimized for the investigation of auditory processing, we examined brain responses induced by temporal novelty in otherwise isochronous sound patterns in musicians and musical laypersons, since the hippocampus has been suggested previously to be crucially involved in various forms of novelty detection. In the first cross-sectional experiment, we identified enhanced neural responses to temporal novelty in the anterior left hippocampus of professional musicians, pointing to expertise-related differences in hippocampal processing. In the second experiment, we evaluated neural responses to acoustic temporal novelty in a longitudinal approach to disentangle training-related changes from predispositional factors. For this purpose, we examined an independent sample of music academy students before and after two semesters of intensive aural skills training. After this training period, hippocampal responses to temporal novelty in sounds were enhanced in musical students, and statistical interaction analysis of brain activity changes over time suggests training rather than predisposition effects. Thus, our results provide direct evidence for functional changes of the adult hippocampus in humans related to musical training.

  20. Direct numerical simulation of human phonation (United States)

    Saurabh, Shakti; Bodony, Daniel


    A direct numerical simulation study of the generation and propagation of the human voice in a full-body domain is conducted. A fully compressible fluid flow model, anatomically representative vocal tract geometry, finite deformation model for vocal fold (VF) motion and a fully coupled fluid-structure interaction model are employed. The dynamics of the multi-layered VF tissue with varying stiffness are solved using a quadratic finite element code. The fluid-solid domains are coupled through a boundary-fitted interface and utilize a Poisson equation-based mesh deformation method. A new inflow boundary condition, based upon a quasi-1D formulation with constant sub-glottal volume velocity, linked to the VF movement, has been adopted. Simulations for both child and adult phonation were performed. Acoustic characteristics obtained from these simulation are consistent with expected values. A sensitivity analysis based on VF stiffness variation is undertaken and sound pressure level/fundamental frequency trends are established. An evaluation of the data against the commonly-used quasi-1D equations suggest that the latter are not sufficient to model phonation. Phonation threshold pressures are measured for several VF stiffness variations and comparisons to clinical data are carried out.

  2. Simulation training program for midwives to manage postpartum hemorrhage: A randomized controlled trial. (United States)

    Kato, Chiho; Kataoka, Yaeko


    To explore the effectiveness of a simulation training program for midwives in performance and knowledge for the management of postpartum hemorrhage (PPH). The study design was a randomized controlled trial. Midwives working at one obstetrics ward in an urban area were randomly assigned to simulation training program or no training. This "simulation program" included pre study e-learning and simulation. Inclusion criteria were midwives who: 1) had two or three years of clinical experience, 2) worked in an obstetrics ward, and 3) had experience with birth assistance. There was one exclusion criterion namely prior experience of simulation training for PPH. Change in performance was evaluated using a PPH scenario performance test at one month after the simulation training. Change in knowledge was evaluated by a 25-item multiple-choice questionnaire completed shortly before the training and one month after the training. The ethical review committee of St Luke's International University granted approval (No. 14-096). Eighty-one midwives were randomly assigned to either the intervention group (n=40) or the control group (n=41). Performance in the simulation training group was significantly better in comparison to the no training group; mean performance score was 23.85(SD 2.71) in the training group versus 18.00(SD 3.01) in the no training group (MD 5.85 95% CI 4.85-7.12, t=9.17, psimulation training group; amount of knowledge score was 3.65(SD 3.40) in the training group versus -0.02(SD 3.02) in the no training group (MD 3.67 95% CI 2.25-5.10, t=5.14, psimulation training. However, assessments of long-term effects on performance, and knowledge and the clinical outcomes in managing of obstetric complications are necessary to adequately evaluate the effectiveness of simulation training.

  3. A systematic review of surgical skills transfer after simulation-based training: laparoscopic cholecystectomy and endoscopy. (United States)

    Dawe, Susan R; Windsor, John A; Broeders, Joris A J L; Cregan, Patrick C; Hewett, Peter J; Maddern, Guy J


    A systematic review to determine whether skills acquired through simulation-based training transfer to the operating room for the procedures of laparoscopic cholecystectomy and endoscopy. Simulation-based training assumes that skills are directly transferable to the operation room, but only a few studies have investigated the effect of simulation-based training on surgical performance. A systematic search strategy that was used in 2006 was updated to retrieve relevant studies. Inclusion of articles was determined using a predetermined protocol, independent assessment by 2 reviewers, and a final consensus decision. Seventeen randomized controlled trials and 3 nonrandomized comparative studies were included in this review. In most cases, simulation-based training was in addition to patient-based training programs. Only 2 studies directly compared simulation-based training in isolation with patient-based training. For laparoscopic cholecystectomy (n = 10 studies) and endoscopy (n = 10 studies), participants who reached simulation-based skills proficiency before undergoing patient-based assessment performed with higher global assessment scores and fewer errors in the operating room than their counterparts who did not receive simulation training. Not all parameters measured were improved. Two of the endoscopic studies compared simulation-based training in isolation with patient-based training with different results: for sigmoidoscopy, patient-based training was more effective, whereas for colonoscopy, simulation-based training was equally effective. Skills acquired by simulation-based training seem to be transferable to the operative setting for laparoscopic cholecystectomy and endoscopy. Future research will strengthen these conclusions by evaluating predetermined competency levels on the same simulators and using objective validated global rating scales to measure operative performance.

  4. A nuclear training simulator implementing a capability for multiple, concurrent-training sessions

    Energy Technology Data Exchange (ETDEWEB)

    Groeneveld, B.J.; Nannister, D.G.; Estes, K.R.; Johnsen, M.R.


    The Advanced Test Reactor (ATR) Simulator at the Test Reactor Area of the Idaho National Engineering Laboratory (INEL) has recently been upgraded to reflect plant installation of a distributed control system (DCS). The ATR Simulator re-design implements traditional needs for software extensibility and plant installation prototyping, but the driving force behind its new design was an instruction requirement for multiple, concurrent-training sessions. Support is provided for up to three concurrent, independent or interacting, training sessions of reactor, balance of plant, and experiment loop operators. This capability has been achieved by modifying the existing design to consistently apply client-server, parent-child, and peer-to-peer processing technologies, and then to encapsulate concurrency software into all interfaces. When the resulting component-oriented design is linked with build and runtime flexibility in a distributed computing environment, traditional needs for extensibility and parallel software and scenario development are satisfied with minimal additional effort. Sensible configuration management practices coupled with the ability to perform piecewise system builds also greatly facilitate prototyping of plant changes prior to installation.

Training on box trainers allows for simulation training at home, which studies have shown to be a feasible method of training. However, little research has been conducted into how to make it a more efficient method of training. Our aim was to investigate how box trainers are used in take-home training to help guide the design of take-home training courses. This study was designed using a mixed methods approach. Junior doctors participating in a laparoscopy curriculum, which included practising at home on box trainers, were invited. Quantitative data on training patterns was collected from logbooks. Qualitative data on the use of box trainers was retrieved from focus groups and individual interviews. From logbooks, we found that 14 out of 18 junior doctors mixed their training modalities, and four practised first on box trainers then on virtual reality simulators. Twelve practised only at home, while five practised at both places and one practised solely at the simulation centre. After a delayed start, most practised for some time, then had a period without training and then started training again towards the end of the course. We found that the themes of the interviews were: training method, training pattern, feedback and self-regulation. Participants identified the lack of feedback as challenging but described how self-rating provided direction during unsupervised training. Mandatory training elements affected when and how much participants practised. When participants practised at home, they took an individualised approach to training. They mixed their training at home with training at the simulation centre. Participants practised at the beginning and towards the end of the course. Self-rating helped to guide unsupervised training where feedback was not accessible. Curricular requirements and testing determined when and how much participants practised.

  7. Simulation Training Versus Real Time Console Training for New Flight Controllers (United States)

    Heaton, Amanda


    For new flight controllers, the two main learning tools are simulations and real time console performance training. These benefit the new flight controllers in different ways and could possibly be improved. Simulations: a) Allow for mistakes without serious consequences. b) Lets new flight controllers learn the working style of other new flight controllers. c) Lets new flight controllers eventually begin to feel like they have mastered the sim world, so therefore they must be competent in the real time world too. Real time: a) Shows new flight controllers some of the unique problems that develop and have to be accounted for when dealing with certain payloads or systems. b) Lets new flight controllers experience handovers - gathering information from the previous shift on what the room needs to be aware of and what still needs to be done. c) Gives new flight controllers confidence that they can succeed in the position they are training for when they can solve real anomalies. How Sims could be improved and more like real-time ops for the ISS Operations Controller position: a) Operations Change Requests to review. b) Fewer anomalies (but still more than real time for practice). c) Payload Planning Manager Handover sheet for the E-1 and E-3 reviews. d) Flight note in system with at least one comment to verify for the E-1 and E-3 reviews How the real time console performance training could be improved for the ISS Operations Controller position: a) Schedule the new flight controller to be on console for four days but with a different certified person each day. This will force them to be the source of knowledge about every OCR in progress, everything that has happened in those few days, and every activity on the timeline. Constellation program flight controllers will have to learn entirely from simulations, thereby losing some of the elements that they will need to have experience with for real time ops. It may help them to practice real time console performance training

  8. Short simulation training improves objective skills in established advanced practitioners managing emergencies on the ward and surgical intensive care unit. (United States)

    Pascual, Jose L; Holena, Daniel N; Vella, Michael A; Palmieri, Joseph; Sicoutris, Corinna; Selvan, Ben; Fox, Adam D; Sarani, Babak; Sims, Carrie; Williams, Noel N; Schwab, Charles William


    Several studies evaluating simulation training in intensive care unit (ICU) physicians have demonstrated improvement in leadership and management skills. No study to date has evaluated whether such training is useful in established ICU advanced practitioners (APs). We hypothesized that human patient simulator-based training would improve surgical ICU APs' skills at managing medical crises. After institutional review board approval, 12 APs completed ½ day of simulation training on the SimMan, Laerdal system. Each subject participated in five scenarios, first as team leader (pretraining scenario), then as observer for three scenarios, and finally, again as team leader (posttraining). Faculty teaching accompanied each scenario and preceded a debriefing session with video replay. Three experts scored emergency care skills (Airway-Breathing-Circulation [ABCs] sequence, recognition of shock, pneumothorax, etc.) and teamwork leadership/interpersonal skills. A multiple choice question examination and training effectiveness questionnaire were completed before and after training. Fellows underwent the same curriculum and served to validate the study. Pre- and postscores were compared using the Wilcoxon signed rank test with two-tailed significance of 0.05. Improvement was seen in participants' scores combining all parameters (73% ± 13% vs. 80% ± 11%, p = 0.018). AP leadership/interpersonal skills (+12%), multiple choice question examination (+4%), and training effectiveness questionnaire (+6%) scores improved significantly (p managing medical emergencies. Such a validated curriculum may be useful as an AP continuing education resource.

    To determine the utility of modern arthroscopic simulators in transferring skills learned on the model to the operating room. A meta-analysis and systematic review of all English-language studies relevant to validated arthroscopic simulation models using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines from 1999 to 2016 was performed. Data collected included the specific simulator model, the joint used, participant demographic characteristics, participant level of training, training session information, type and number of tasks, pre- and post-training assessments, and overall outcomes of simulator performance. Three independent reviewers analyzed all studies. Fifty-seven studies with 1,698 participants met the study criteria and were included. Of the studies, 25 (44%) incorporated an arthroscopic training program into the study methods whereas 32 (56%) did not. In 46 studies (81%), the studies' respective simulator models were used to assess arthroscopic performance, whereas 9 studies (16%) used Sawbones models, 8 (14%) used cadaveric models, and 4 (7%) evaluated subject performance on a live patient in the operating room. In 21 studies (37%), simulator performance was compared with experience level, with 20 of these (95%) showing that clinical experience correlated with simulator performance. In 25 studies (44%), task performance was evaluated before and after simulator training, with 24 of these (96%) showing improvement after training. All 4 studies that included live-patient arthroscopy reported improved operating room performance after simulator training compared with the performance of subjects not participating in a training program. This review suggests that (1) training on arthroscopic simulators improves performance on arthroscopic simulators and (2) performance on simulators for basic diagnostic arthroscopy correlates with experience level. Limited data suggest that simulator training can improve basic diagnostic

  11. Surgical resident training using real-time simulation of cardiopulmonary bypass physiology with echocardiography. (United States)

    Martin, Jeremiah T; Reda, Hassan; Dority, Jeremy S; Zwischenberger, Joseph B; Hassan, Zaki-Udin


    With increasing complexity of medical care and continuing limitations on medical education, the use of simulation is becoming ever more important. Several simulators have been developed to teach procedural-based surgical tasks. The care of the cardiac surgical patient requires an in-depth understanding of physiology, particularly as pertains to cardiopulmonary bypass. We describe the use of the Human Patient Simulator (HPS) to teach perioperative fundamentals to surgical residents. General surgery residents from the University of Kentucky participated in an interactive simulation pilot program. The METI (Medical Education Technology, Inc, Sarasota, Florida) HPS was used with custom programming to demonstrate simulated intraoperative and postoperative physiology related to cardiopulmonary bypass. Didactics, in addition to intraoperative echocardiographic images, were provided. Fund of knowledge was assessed by a computerized pre- and posttest that was administered to the trainees, and self-assessment data were collected using a Likert scale. Nineteen general surgery residents participated. An overall improvement in performance on the test was demonstrated from 63% correct to 85% correct. In general, residents found the simulation useful, appreciated the opportunity to treat crisis situations without risk of harm to a patient, and felt they could apply the knowledge gained from this program in their future practice. Simulation serves as a useful adjunct to medical education. We have demonstrated the use of the HPS to provide a real-time simulation of the physiology of cardiopulmonary bypass and postoperative care. We plan to use this system as part of our standard curriculum of training rotating residents and junior fellows and anticipate this system could be used as part of future cardiothoracic simulations.

  12. Biomedical Simulation Models of Human Auditory Processes (United States)

    Bicak, Mehmet M. A.


    Detailed acoustic engineering models that explore noise propagation mechanisms associated with noise attenuation and transmission paths created when using hearing protectors such as earplugs and headsets in high noise environments. Biomedical finite element (FE) models are developed based on volume Computed Tomography scan data which provides explicit external ear, ear canal, middle ear ossicular bones and cochlea geometry. Results from these studies have enabled a greater understanding of hearing protector to flesh dynamics as well as prioritizing noise propagation mechanisms. Prioritization of noise mechanisms can form an essential framework for exploration of new design principles and methods in both earplug and earcup applications. These models are currently being used in development of a novel hearing protection evaluation system that can provide experimentally correlated psychoacoustic noise attenuation. Moreover, these FE models can be used to simulate the effects of blast related impulse noise on human auditory mechanisms and brain tissue.

    Qiao, Weiguang; Bai, Yang; Lv, Ruxi; Zhang, Wendi; Chen, Yuqing; Lei, Shan; Zhi, Fachao


    Advances in virtual endoscopy simulators have paralleled an interest in medical simulation for gastrointestinal endoscopy training. The primary objective was to determine whether the virtual endoscopy simulator training could improve the performance of novices. A systematic review. Randomized controlled trials (RCTs) that compared virtual endoscopy simulator training with bedside teaching or any other intervention for novices were collected. Novice endoscopists. The PRISMA statement was followed during the course of the research. The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and ScienceDirect were searched (up to July 2013). Data extraction and assessment were independently performed. Independent procedure completion, total procedure time and required assistance. Fifteen studies (n = 354) were eligible for inclusion: 9 studies designed for colonoscopy training, 6 for gastroscopy training. For gastroscopy training, procedure completed independently was reported in 87.7% of participants in simulator training group compared to 70.0% of participants in control group (1 study; 22 participants; RR 1.25; 95% CI 1.13-1.39; Ptraining, procedure completed independently was reported in 89.3% of participants in simulator training group compared to 88.9% of participants in control group (7 study; 163 participants; RR 1.10; 95% CI 0.88-1.37; P = 0.41; I(2) = 85%). The included studies are quite in-homogeneous with respect to training schedule and procedure. Virtual endoscopy simulator training might be effective for gastroscopy, but so far no data is available to support this for colonoscopy.

  15. Direct numerical simulation of human phonation (United States)

    Bodony, Daniel; Saurabh, Shakti


    The generation and propagation of the human voice in three-dimensions is studied using direct numerical simulation. A full body domain is employed for the purpose of directly computing the sound in the region past the speaker's mouth. The air in the vocal tract is modeled as a compressible and viscous fluid interacting with the elastic vocal folds. The vocal fold tissue material properties are multi-layered, with varying stiffness, and a linear elastic transversely isotropic model is utilized and implemented in a quadratic finite element code. The fluid-solid domains are coupled through a boundary-fitted interface and utilize a Poisson equation-based mesh deformation method. A kinematic constraint based on a specified minimum gap between the vocal folds is applied to prevent collision during glottal closure. Both near VF flow dynamics and far-field acoustics have been studied. A comparison is drawn to current two-dimensional simulations as well as to data from the literature. Near field vocal fold dynamics and glottal flow results are studied and in good agreement with previous three-dimensional phonation studies. Far-field acoustic characteristics, when compared to their two-dimensional counterpart, are shown to be sensitive to the dimensionality.

  16. [The importance of simulation in team training on obstetric emergencies: results of the first phase of the national plan for continuous medical training]. (United States)

    Maio Matos, Francisco; Sousa Gomes, Andrea; Costa, Fernando Jorge; Santos Silva, Isabel; Carvalhas, Joana


    Obstetric emergencies are unexpected and random. The traditional model for medical training of these acute events has included lectures combined with sporadic clinical experiences, but this educational method has inherent limitations. Given the variety of manual skills that must be learned and high-risk environment, Obstetrics is uniquely suited for simulation. New technological educational tools provide an opportunity to learn and master technical skills needed in emergent situations as well as the opportunity to rehearse and learn from mistakes without risks to patients. The goals of this study are to assess which are the factors that trainees associate to human fallibility before and after clinical simulation based training; to compare the confidence level to solve emergent obstetric situations between interns and experts with up to 5 years of experience before and after training, and to determine the value that trainees give to simulation as a teaching tool on emergent events. 31 physicians participated at this course sessions. After the course, we verified changes in the factores that trainees associate to human fallibility, an increase in confidence level to solve emergent obstetric and an increase in the value that trainees give to simulation as a teaching tool.

    Stress influences numerous psychological and physiological processes, and its effects have practical implications in a variety of professions and real-world activities. However, few studies have concurrently assessed multiple behavioral, hormonal, nutritional and heart-rate responses of humans to acute, severe stress. This investigation simultaneously assessed cognitive, affective, hormonal, and heart-rate responses induced by an intensely stressful real-world environment designed to simulate wartime captivity. Sixty males were evaluated during and immediately following participation in U.S. Army Survival, Evasion, Resistance, and Escape (SERE) school, three weeks of intense but standardized training for Soldiers at risk of capture. Simulated captivity and intense mock interrogations degraded grammatical reasoning (pworking memory (pnutritional status and heart rate are simultaneously altered, and each of these subsequently recovers at different rates.

  20. Human-simulation-based learning to prevent medication error: A systematic review. (United States)

    Sarfati, Laura; Ranchon, Florence; Vantard, Nicolas; Schwiertz, Vérane; Larbre, Virginie; Parat, Stéphanie; Faudel, Amélie; Rioufol, Catherine


    In the past 2 decades, there has been an increasing interest in simulation-based learning programs to prevent medication error (ME). To improve knowledge, skills, and attitudes in prescribers, nurses, and pharmaceutical staff, these methods enable training without directly involving patients. However, best practices for simulation for healthcare providers are as yet undefined. By analysing the current state of experience in the field, the present review aims to assess whether human simulation in healthcare helps to reduce ME. A systematic review was conducted on Medline from 2000 to June 2015, associating the terms "Patient Simulation," "Medication Errors," and "Simulation Healthcare." Reports of technology-based simulation were excluded, to focus exclusively on human simulation in nontechnical skills learning. Twenty-one studies assessing simulation-based learning programs were selected, focusing on pharmacy, medicine or nursing students, or concerning programs aimed at reducing administration or preparation errors, managing crises, or learning communication skills for healthcare professionals. The studies varied in design, methodology, and assessment criteria. Few demonstrated that simulation was more effective than didactic learning in reducing ME. This review highlights a lack of long-term assessment and real-life extrapolation, with limited scenarios and participant samples. These various experiences, however, help in identifying the key elements required for an effective human simulation-based learning program for ME prevention: ie, scenario design, debriefing, and perception assessment. The performance of these programs depends on their ability to reflect reality and on professional guidance. Properly regulated simulation is a good way to train staff in events that happen only exceptionally, as well as in standard daily activities. By integrating human factors, simulation seems to be effective in preventing iatrogenic risk related to ME, if the program is

  5. Reducing the number of animals used for microsurgery training programs by using a task-trainer simulator. (United States)

    Guerreschi, P; Qassemyar, A; Thevenet, J; Hubert, T; Fontaine, C; Duquennoy-Martinot, V


    To master the skills needed for microsurgery techniques, residents must enrol in a long and complex training program that includes manipulations on simulators, on ex vivo tissues and finally in vivo training. This final step consists of performing vascular anastomoses on murine models. We propose here a simulation program designed to decrease the number of rats used during the final in vivo training. Our study presents the materials used, the various exercises proposed and their evaluations. Two identical student groups were compared in the framework of the University Diploma of Microsurgery. Group A (seven students) followed a classic training program, all of whom achieved permeable vascular anastomoses. A total of 149 rats were needed for this group. Group B (seven students) first validated their manipulations on the task-trainer simulation program. A mean of 6 h was necessary to obtain this validation. All these students achieved the required permeable vascular anastomoses but only 77 rats were used for this group. This simulation program spared 72 rats, abiding by the Russell and Burch concept of a humane experimental technique, namely the 3R principles. This home-made, cost-efficient and easy-to-use task trainer included various exercises with increasing difficulty levels and a progressive scoring system. We believe that microsurgery training needs to include both simple and sophisticated tools in order to reduce the number of animals used to master these surgical skills.

    Simulation-based training is a widespread strategy to improve health-care quality. However, its effect on registered nurses has previously not been established in systematic reviews. The aim of this systematic review is to evaluate effect of simulation-based training on nurses' skills and knowledge. We searched CDSR, DARE, HTA, CENTRAL, CINAHL, MEDLINE, Embase, ERIC, and SveMed+ for randomised controlled trials (RCT) evaluating effect of simulation-based training among nurses. Searches were completed in December 2016. Two reviewers independently screened abstracts and full-text, extracted data, and assessed risk of bias. We compared simulation-based training to other learning strategies, high-fidelity simulation to other simulation strategies, and different organisation of simulation training. Data were analysed through meta-analysis and narrative syntheses. GRADE was used to assess the quality of evidence. Fifteen RCTs met the inclusion criteria. For the comparison of simulation-based training to other learning strategies on nurses' skills, six studies in the meta-analysis showed a significant, but small effect in favour of simulation (SMD -1.09, CI -1.72 to -0.47). There was large heterogeneity (I 2 85%). For the other comparisons, there was large between-study variation in results. The quality of evidence for all comparisons was graded as low. The effect of simulation-based training varies substantially between studies. Our meta-analysis showed a significant effect of simulation training compared to other learning strategies, but the quality of evidence was low indicating uncertainty. Other comparisons showed inconsistency in results. Based on our findings simulation training appears to be an effective strategy to improve nurses' skills, but further good-quality RCTs with adequate sample sizes are needed.

  8. Predictive validity of a training protocol using a robotic surgery simulator. (United States)

    Culligan, Patrick; Gurshumov, Emil; Lewis, Christa; Priestley, Jennifer; Komar, Jodie; Salamon, Charbel


    Robotic surgery simulation may provide a way for surgeons to acquire specific robotic surgical skills without practicing on live patients. Five robotic surgery experts performed 10 simulator skills to the best of their ability, and thus, established expert benchmarks for all parameters of these skills. A group of credentialed gynecologic surgeons naive to robotics practiced the simulator skills until they were able to perform each one as well as our experts. Within a week of doing so, they completed robotic pig laboratory training, after which they performed supracervical hysterectomies as their first-ever live human robotic surgery. Time, blood loss, and blinded assessments of surgical skill were compared among the experts, novices, and a group of control surgeons who had robotic privileges but no simulator exposure. Sample size estimates called for 11 robotic novices to achieve 90% power to detect a 1 SD difference between operative times of experts and novices (α = 0.05). Fourteen novice surgeons completed the study-spending an average of 20 hours (range, 9.7-38.2 hours) in the simulation laboratory to pass the expert protocol. The mean operative times for the expert and novices were 20.2 (2.3) and 21.7 (3.3) minutes, respectively (P = 0.12; 95% confidence interval, -1.7 to 4.7), whereas the mean time for control surgeons was 30.9 (0.6) minutes (P robotic simulator skills translated to expert-level surgical times during live human surgery. As such, we have established predictive validity of this protocol.

    Virtual reality (VR) simulators enrich surgical training and offer training possibilities outside of the operating room (OR). In this study, we created a criterion-based training program on a VR simulator with haptic feedback and tested it by comparing the performances of a simulator group against a control group. Medical students with no experience in laparoscopy were randomly assigned to a simulator group or a control group. In the simulator group, the candidates trained until they reached predefined criteria on the LapSim ® VR simulator (Surgical Science AB, Göteborg, Sweden) with haptic feedback (Xitact TM IHP, Mentice AB, Göteborg, Sweden). All candidates performed a cholecystectomy on a porcine organ model in a box trainer (the clinical setting). The performances were video rated by two surgeons blinded to subject training status. In total, 30 students performed the cholecystectomy and had their videos rated (N = 16 simulator group, N = 14 control group). The control group achieved better video rating scores than the simulator group (p training program did not transfer skills to the clinical setting. Poor mechanical performance of the simulated haptic feedback is believed to have resulted in a negative training effect.

  10. A Simulated Annealing Approach for the Train Design Optimization Problem

    Directory of Open Access Journals (Sweden)

    Federico Alonso-Pecina


    Full Text Available The Train Design Optimization Problem regards making optimal decisions on the number and movement of locomotives and crews through a railway network, so as to satisfy requested pick-up and delivery of car blocks at stations. In a mathematical programming formulation, the objective function to minimize is composed of the costs associated with the movement of locomotives and cars, the loading/unloading operations, the number of locomotives, and the crews’ return to their departure stations. The constraints include upper bounds for number of car blocks per locomotive, number of car block swaps, and number of locomotives passing through railroad segments. We propose here a heuristic method to solve this highly combinatorial problem in two steps. The first one finds an initial, feasible solution by means of an ad hoc algorithm. The second step uses the simulated annealing concept to improve the initial solution, followed by a procedure aiming to further reduce the number of needed locomotives. We show that our results are competitive with those found in the literature.

    Full Text Available Abstract Objectives This study shows the development and validation of a dental anesthesia-training simulator, specifically for the inferior alveolar nerve block (IANB. The system developed provides the tactile sensation of inserting a real needle in a human patient, using Virtual Reality (VR techniques and a haptic device that can provide a perceived force feedback in the needle insertion task during the anesthesia procedure. Material and Methods To simulate a realistic anesthesia procedure, a Carpule syringe was coupled to a haptic device. The Volere method was used to elicit requirements from users in the Dentistry area; Repeated Measures Two-Way ANOVA (Analysis of Variance, Tukey post-hoc test and averages for the results’ analysis. A questionnaire-based subjective evaluation method was applied to collect information about the simulator, and 26 people participated in the experiments (12 beginners, 12 at intermediate level, and 2 experts. The questionnaire included profile, preferences (number of viewpoints, texture of the objects, and haptic device handler, as well as visual (appearance, scale, and position of objects and haptic aspects (motion space, tactile sensation, and motion reproduction. Results The visual aspect was considered appropriate and the haptic feedback must be improved, which the users can do by calibrating the virtual tissues’ resistance. The evaluation of visual aspects was influenced by the participants’ experience, according to ANOVA test (F=15.6, p=0.0002, with p<0.01. The user preferences were the simulator with two viewpoints, objects with texture based on images and the device with a syringe coupled to it. Conclusion The simulation was considered thoroughly satisfactory for the anesthesia training, considering the needle insertion task, which includes the correct insertion point and depth, as well as the perception of tissues resistances during the insertion.

  13. Role of in-situ simulation for training in healthcare: opportunities and challenges. (United States)

    Kurup, Viji; Matei, Veronica; Ray, Jessica


    Simulation has now been acknowledged as an important part of training in healthcare, and most academic hospitals have a dedicated simulation center. In-situ simulation occurs in patient care units with scenarios involving healthcare professionals in their actual working environment. The purpose of this review is to describe the process of putting together the components of in-situ simulation for training programs and to review outcomes studied, and challenges with this approach. In-situ simulation has been used to 'test-drive' new centers, train personnel in new procedures in existing centers, for recertification training and to uncover latent threats in clinical care areas. It has also emerged as an attractive alternative to traditional simulations for institutions that do not have their own simulation center. In-situ simulation can be used to improve reliability and safety especially in areas of high risk, and in high-stress environments. It is also a reasonable and attractive alternative for programs that want to conduct interdisciplinary simulations for their trainees and faculty, and for those who do not have access to a fully functional simulation center. Further research needs to be done in assessing effectiveness of training using this method and the effect of such training on clinical outcomes.

  15. A Simulation-Based Approach to Training Operational Cultural Competence (United States)

    Johnson, W. Lewis


    Cultural knowledge and skills are critically important for military operations, emergency response, or any job that involves interaction with a culturally diverse population. However, it is not obvious what cultural knowledge and skills need to be trained, and how to integrate that training with the other training that trainees must undergo. Cultural training needs to be broad enough to encompass both regional (culture-specific) and cross-cultural (culture-general) competencies, yet be focused enough to result in targeted improvements in on-the-job performance. This paper describes a comprehensive instructional development methodology and training technology framework that focuses cultural training on operational needs. It supports knowledge acquisition, skill acquisition, and skill transfer. It supports both training and assessment, and integrates with other aspects of operational skills training. Two training systems will be used to illustrate this approach: the Virtual Cultural Awareness Trainer (VCAT) and the Tactical Dari language and culture training system. The paper also discusses new and emerging capabilities that are integrating cultural competence training more strongly with other aspects of training and mission rehearsal.

    Brewin, James; Tang, Jessica; Dasgupta, Prokar; Khan, Muhammad S; Ahmed, Kamran; Bello, Fernando; Kneebone, Roger; Jaye, Peter


    To evaluate the face, content and construct validity of the distributed simulation (DS) environment for technical and non-technical skills training in endourology. To evaluate the educational impact of DS for urology training. DS offers a portable, low-cost simulated operating room environment that can be set up in any open space. A prospective mixed methods design using established validation methodology was conducted in this simulated environment with 10 experienced and 10 trainee urologists. All participants performed a simulated prostate resection in the DS environment. Outcome measures included surveys to evaluate the DS, as well as comparative analyses of experienced and trainee urologist's performance using real-time and 'blinded' video analysis and validated performance metrics. Non-parametric statistical methods were used to compare differences between groups. The DS environment demonstrated face, content and construct validity for both non-technical and technical skills. Kirkpatrick level 1 evidence for the educational impact of the DS environment was shown. Further studies are needed to evaluate the effect of simulated operating room training on real operating room performance. This study has shown the validity of the DS environment for non-technical, as well as technical skills training. DS-based simulation appears to be a valuable addition to traditional classroom-based simulation training. © 2014 The Authors BJU International © 2014 BJU International Published by John Wiley & Sons Ltd.

  17. [Evaluation of simulated mandibular models in skill training of implantology for dental undergraduates]. (United States)

    Xu, Feng-Wei; Shang, Jiang; Song, Jian; DU, Ping-Gong; Liu, Zhong-Hao


    To explore the effects of simulated mandibular models in skill training of implantology for dental undergraduate. Pre-clinical teaching of oral implantology was implemented on simulation models for 51 undergraduates of grade 2013. Each undergraduate inserted a dental implant and took an impression in the simulation model under the teacher's guidance. After the training course, the scores were evaluated both objectively and subjectively. An average score of 91.6 was obtained in the course of oral implantology on simulated mandibular models. All students appreciated the teaching methods. They believed that training on simulation models could improve their learning interest and arouse their learning motivation. Simulated mandibular models are good tools in training of oral implantology for dental undergraduates education, which is worthy of wide application.

  18. Evaluation of a haptics-based virtual reality temporal bone simulator for anatomy and surgery training. (United States)

    Fang, Te-Yung; Wang, Pa-Chun; Liu, Chih-Hsien; Su, Mu-Chun; Yeh, Shih-Ching


    Virtual reality simulation training may improve knowledge of anatomy and surgical skills. We evaluated a 3-dimensional, haptic, virtual reality temporal bone simulator for dissection training. The subjects were 7 otolaryngology residents (3 training sessions each) and 7 medical students (1 training session each). The virtual reality temporal bone simulation station included a computer with software that was linked to a force-feedback hand stylus, and the system recorded performance and collisions with vital anatomic structures. Subjects performed virtual reality dissections and completed questionnaires after the training sessions. Residents and students had favorable responses to most questions of the technology acceptance model (TAM) questionnaire. The average TAM scores were above neutral for residents and medical students in all domains, and the average TAM score for residents was significantly higher for the usefulness domain and lower for the playful domain than students. The average satisfaction questionnaire for residents showed that residents had greater overall satisfaction with cadaver temporal bone dissection training than training with the virtual reality simulator or plastic temporal bone. For medical students, the average comprehension score was significantly increased from before to after training for all anatomic structures. Medical students had significantly more collisions with the dura than residents. The residents had similar mean performance scores after the first and third training sessions for all dissection procedures. The virtual reality temporal bone simulator provided satisfactory training for otolaryngology residents and medical students. Copyright © 2013. Published by Elsevier Ireland Ltd.

  19. Simulation-based training for thoracoscopic lobectomy: a randomized controlled trial: virtual-reality versus black-box simulation. (United States)

    Jensen, Katrine; Ringsted, Charlotte; Hansen, Henrik Jessen; Petersen, René Horsleben; Konge, Lars


    Video-assisted thoracic surgery is gradually replacing conventional open thoracotomy as the method of choice for the treatment of early-stage non-small cell lung cancers, and thoracic surgical trainees must learn and master this technique. Simulation-based training could help trainees overcome the first part of the learning curve, but no virtual-reality simulators for thoracoscopy are commercially available. This study aimed to investigate whether training on a laparoscopic simulator enables trainees to perform a thoracoscopic lobectomy. Twenty-eight surgical residents were randomized to either virtual-reality training on a nephrectomy module or traditional black-box simulator training. After a retention period they performed a thoracoscopic lobectomy on a porcine model and their performance was scored using a previously validated assessment tool. The groups did not differ in age or gender. All participants were able to complete the lobectomy. The performance of the black-box group was significantly faster during the test scenario than the virtual-reality group: 26.6 min (SD 6.7 min) versus 32.7 min (SD 7.5 min). No difference existed between the two groups when comparing bleeding and anatomical and non-anatomical errors. Simulation-based training and targeted instructions enabled the trainees to perform a simulated thoracoscopic lobectomy. Traditional black-box training was more effective than virtual-reality laparoscopy training. Thus, a dedicated simulator for thoracoscopy should be available before establishing systematic virtual-reality training programs for trainees in thoracic surgery.

  20. Comparison of 2 training programs for basic laparoscopic skills and simulated surgery performance in veterinary students. (United States)

    Chen, Chi-Ya; Ragle, Claude A; Lencioni, Rachael; Fransson, Boel A


    To compare the effects of 2 training curricula on laparoscopic skills and performance of simulated surgery in veterinary students. Prospective study. Veterinary students (n = 33) with no prior hands-on experience in minimally invasive surgery. Basic laparoscopic skills (BLS) were assessed based on 5 modified McGill inanimate system for training and evaluation of laparoscopic skills. Motion metrics and an objective structured assessment of technical skills (OSATS) were used to evaluate surgical skills during a simulated laparoscopic cholecystectomy performed in an augmented reality simulator. Students were randomly assigned to either skill-based (group A) or procedural-based (group B) training curriculum. Both tests were performed prior to and after a 10-session training curriculum. Post-training BLS results were improved in both training groups (P difference was detected in OSATS before and after training. Both training curricula improved BLS, but significant differences were not detected between the procedural-based training program and basic skills training alone in veterinary students. Motion metrics such as time, economy of movement, and instrument path were superior to an OSATS, when assessing surgical performance. Further studies are needed to compare the effects of different simulators on the training of veterinarians with diverse laparoscopic surgical experience. © 2017 The American College of Veterinary Surgeons.

  4. Review-Research on the physical training model of human body based on HQ. (United States)

    Junjie, Liu


    Health quotient (HQ) is the newest health culture and concept in the 21st century, and the analysis of the human body sports model is not enough mature at present, what's more, the purpose of this paper is to study the integration of the two subjects the health quotient and the sport model. This paper draws the conclusion that physical training and education in colleges and universities can improve the health quotient, and it will make students possess a more healthy body and mind. Then through a new rigid body model of sports to simulate the human physical exercise. After that this paper has an in-depth study on the dynamic model of the human body movement on the basis of establishing the matrix and equation. The simulation results of the human body bicycle riding and pole throwing show that the human body joint movement simulation can be realized and it has a certain operability as well. By means of such simulated calculation, we can come to a conclusion that the movement of the ankle joint, knee joint and hip joint's motion law and real motion are basically the same. So it further verify the accuracy of the motion model, which lay the foundation of other research movement model, also, the study of the movement model is an important method in the study of human health in the future.

  5. Training affects muscle phospholipid fatty acid composition in humans

    Helge, Jørn Wulff; Wu, B J; Willer, Mette


    Training improves insulin sensitivity, which in turn may affect performance by modulation of fuel availability. Insulin action, in turn, has been linked to specific patterns of muscle structural lipids in skeletal muscle. This study investigated whether regular exercise training exerts an effect...... on the muscle membrane phospholipid fatty acid composition in humans. Seven male subjects performed endurance training of the knee extensors of one leg for 4 wk. The other leg served as a control. Before, after 4 days, and after 4 wk, muscle biopsies were obtained from the vastus lateralis. After 4 wk......, the phospholipid fatty acid contents of oleic acid 18:1(n-9) and docosahexaenoic acid 22:6(n-3) were significantly higher in the trained (10.9 +/- 0.5% and 3.2 +/- 0.4% of total fatty acids, respectively) than the untrained leg (8.8 +/- 0.5% and 2.6 +/- 0.4%, P

  6. Simulation-based driver and vehicle crew training: applications, efficacy and future directions. (United States)

    Goode, Natassia; Salmon, Paul M; Lenné, Michael G


    Simulation is widely used as a training tool in many domains, and more recently the use of vehicle simulation as a tool for driver and vehicle crew training has become popular (de Winter et al., 2009; Pradhan et al., 2009). This paper presents an overview of how vehicle simulations are currently used to train driving-related procedural and higher-order cognitive skills, and team-based procedural and non-technical teamwork skills for vehicle crews, and evaluates whether there is evidence these training programs are effective. Efficacy was evaluated in terms of whether training achieves learning objectives and whether the attainment of those objectives enhances real world performance on target tasks. It was concluded that while some higher-order cognitive skills training programs have been shown to be effective, in general the adoption of simulation technology has far outstripped the pace of empirical research in this area. The paper concludes with a discussion of the issues that require consideration when developing and evaluating vehicle simulations for training purposes - based not only on what is known from the vehicle domain, but what can be inferred from other domains in which simulation is an established training approach, such as aviation (e.g. Jentsch et al., 2011) and medicine (e.g. McGaghie et al., 2010). STATEMENT OF RELEVANCE: Simulation has become a popular tool for driver and vehicle crew training in civilian and military settings. This review considers whether there is evidence that this training method leads to learning and the transfer of skills to real world performance. Evidence from other domains, such as aviation and medicine, is drawn upon to inform the design and evaluation of future vehicle simulation training systems.

  7. Integrating Soft Set Theory and Fuzzy Linguistic Model to Evaluate the Performance of Training Simulation Systems (United States)

    Chang, Kuei-Hu; Chang, Yung-Chia; Chain, Kai; Chung, Hsiang-Yu


    The advancement of high technologies and the arrival of the information age have caused changes to the modern warfare. The military forces of many countries have replaced partially real training drills with training simulation systems to achieve combat readiness. However, considerable types of training simulation systems are used in military settings. In addition, differences in system set up time, functions, the environment, and the competency of system operators, as well as incomplete information have made it difficult to evaluate the performance of training simulation systems. To address the aforementioned problems, this study integrated analytic hierarchy process, soft set theory, and the fuzzy linguistic representation model to evaluate the performance of various training simulation systems. Furthermore, importance–performance analysis was adopted to examine the influence of saving costs and training safety of training simulation systems. The findings of this study are expected to facilitate applying military training simulation systems, avoiding wasting of resources (e.g., low utility and idle time), and providing data for subsequent applications and analysis. To verify the method proposed in this study, the numerical examples of the performance evaluation of training simulation systems were adopted and compared with the numerical results of an AHP and a novel AHP-based ranking technique. The results verified that not only could expert-provided questionnaire information be fully considered to lower the repetition rate of performance ranking, but a two-dimensional graph could also be used to help administrators allocate limited resources, thereby enhancing the investment benefits and training effectiveness of a training simulation system.

  9. Localised cutaneous microvascular adaptation to exercise training in humans. (United States)

    Atkinson, Ceri L; Carter, Howard H; Thijssen, Dick H J; Birk, Gurpreet K; Cable, N Timothy; Low, David A; Kerstens, Floortje; Meeuwis, Iris; Dawson, Ellen A; Green, Daniel J


    Exercise training induces adaptation in conduit and resistance arteries in humans, partly as a consequence of repeated elevation in blood flow and shear stress. The stimuli associated with intrinsic cutaneous microvascular adaptation to exercise training have been less comprehensively studied. We studied 14 subjects who completed 8-weeks cycle ergometer training, with partial cuff inflation on one forearm to unilaterally attenuate cutaneous blood flow responses during each exercise-training bout. Before and after training, bilateral forearm skin microvascular dilation was determined using cutaneous vascular conductance (CVC: skin flux/blood pressure) responses to gradual localised heater disk stimulation performed at rest (33, 40, 42 and 44 °C). Cycle exercise induced significant increases in forearm cutaneous flux and temperature, which were attenuated in the cuffed arm (2-way ANOVA interaction-effect; P < 0.01). We found that forearm CVC at 42 and 44 °C was significantly lower in the uncuffed arm following 8-weeks of cycle training (P < 0.01), whereas no changes were apparent in the contralateral cuffed arm (P = 0.77, interaction-effect P = 0.01). Lower limb exercise training in healthy young men leads to lower CVC-responses to a local heating stimulus, an adaptation mediated, at least partly, by a mechanism related to episodic increases in skin blood flow and/or skin temperature.

  15. Use of simulation training to prepare pharmacy residents for medical emergencies. (United States)

    Thompson Bastin, Melissa L; Cook, Aaron M; Flannery, Alexander H


    The use of high-fidelity simulation training for preparing pharmacy residents for various high-stress and high-impact medical emergencies and the impact of this training on pharmacy residents' perception of preparedness are described. During the 2015-16 residency year at the University of Kentucky Medical Center, simulation training, in addition to lecture-based orientation training, was chosen as a method to reinforce skills and knowledge learned throughout the orientation, before residents began working on-call shifts. Three different simulation exercises were developed to cover five selected topics over the course of 3 different days: sepsis as its own session, a surgical-themed session combining bleeding reversal and malignant hyperthermia, and a neurologic-themed session combining stroke and status epilepticus. Postgraduate year 2 (PGY2) specialty residents in critical care and emergency medicine helped facilitate the cases. The specialty residents played the role of the physician or nurse for the case and were allowed to answer questions asked of the pharmacy residents, appropriate to their respective roles. Following completion of the simulation exercise, a survey tool was sent to pharmacy residents to rate their perception of preparedness before and after the training for each scenario and again at 6 months after the simulation training to assess sustainability of the training. Participants generally responded that the simulations met their expectations and that the PGY2 residents facilitated the simulations fairly well (scores of 68.5-80 on a scale of 0-100). The resident-reported that beneficial effects of simulation training persisted at 6 months following the simulation exercises. Simulation training increased pharmacy residents' self-reported preparedness for high-stress, high-impact clinical scenarios and medical emergencies.

  16. The impact of social context on learning and cognitive demands for interactive virtual human simulations

    Directory of Open Access Journals (Sweden)

    Rebecca Lyons


    Full Text Available Interactive virtual human (IVH simulations offer a novel method for training skills involving person-to-person interactions. This article examines the effectiveness of an IVH simulation for teaching medical students to assess rare cranial nerve abnormalities in both individual and small-group learning contexts. Individual (n = 26 and small-group (n = 30 interaction with the IVH system was manipulated to examine the influence on learning, learner engagement, perceived cognitive demands of the learning task, and instructional efficiency. Results suggested the IVH activity was an equally effective and engaging instructional tool in both learning structures, despite learners in the group learning contexts having to share hands-on access to the simulation interface. Participants in both conditions demonstrated a significant increase in declarative knowledge post-training. Operation of the IVH simulation technology imposed moderate cognitive demand but did not exceed the demands of the task content or appear to impede learning.

  17. Clinical Simulation Training in Geriatric Medicine: A Review of the Evidence and Lessons for Training in Psychiatry of Old Age. (United States)

    Plakiotis, Christos


    Clinical simulation encompasses a broad range of methods and techniques that allow clinical skills to be rehearsed and practiced away from the clinic before being applied to real patients. As such, preparation of doctors and other healthcare professionals for safe clinical practice is one of its main aims. The objective of this paper was to review the evidence regarding the use of clinical simulation training in geriatric medicine education and consider how the findings may be translated to education in the closely related field of psychiatry of old age. Original papers and descriptive case studies of clinical simulation training programs for medical professionals were considered for inclusion. Papers were grouped according to the participants' level of training: (1) undergraduate medical education; (2) postgraduate medical education; and (3) multiple levels of medical learners. A diverse range of effective simulation modalities for teaching geriatric medicine was identified across all levels of learning. The evidence suggests that there is much fertile ground for trainees in geriatric medicine and psychiatry of old age to participate in joint simulation training programs, thereby maximising their reach while minimising associated resource requirements and financials costs. Given the prominent position of psychiatry of old age at the interface between psychiatry and medicine, old age psychiatrists potentially have much to offer in advancing the field of clinical simulation while simultaneously improving patient care.

  18. Efficacy of Eyesi surgical simulator training in improving high-tension capsules capsulorhexis performance

    Tiago Bisol

    Full Text Available ABSTRACT Purpose: To evaluate if Eyesi cataract surgical simulator training using its standard course curriculum is effective in improving performance of cataract surgery trainees on creating capsulorhexis on high-tension capsules on the simulator. Methods: We retrospectively analyzed training reports of ophthalmic surgery trainees (2nd and 3rd year residents and cataract fellowship trainees that have accomplished the standard Eyesi cataract surgery simulator training course version 2.1 between May 2012 and August 2013 at Instituto de Diagnostico e Terapia Ocular, Rio de Janeiro, Brazil. We compared the mean score (from 0 to 100 attributed by the simulator on performing the same task, a capsulorhexis on a high-tension capsule, on the surgical simulator "before training" (during beginning of the course and "after training" (at later stages of the course. Results: Thirty-seven trainees' reports were analyzed. Mean and standard deviation "before training" high-tension capsulorhexis score was 41.73 ± 27.08 points and the mean "after training" score was 72.55 ± 16.40 points, a difference of +30.82 points (p value <0.001 on Paired t test, representing a 73% improvement on performance. Conclusions: Eyesi surgical simulator training on course version 2.1 curriculum was effective in improving performance of cataract surgery trainees on creating capsulorhexis on high-tension capsules.

  19. Implementation of laparoscopic virtual-reality simulation training in gynaecology: a mixed-methods design. (United States)

    Burden, Christy; Appleyard, Tracy-Louise; Angouri, Jo; Draycott, Timothy J; McDermott, Leanne; Fox, Robert


    Virtual-reality (VR) training has been demonstrated to improve laparoscopic surgical skills in the operating theatre. The incorporation of laparoscopic VR simulation into surgical training in gynaecology remains a significant educational challenge. We undertook a pilot study to assess the feasibility of the implementation of a laparoscopic VR simulation programme into a single unit. An observational study with qualitative analysis of semi-structured group interviews. Trainees in gynaecology (n=9) were scheduled to undertake a pre-validated structured training programme on a laparoscopic VR simulator (LapSim(®)) over six months. The main outcome measure was the trainees' progress through the training modules in six months. Trainees' perceptions of the feasibility and barriers to the implementation of laparoscopic VR training were assessed in focus groups after training. Sixty-six percent of participants completed six of ten modules. Overall, feedback from the focus groups was positive; trainees felt training improved their dexterity, hand-eye co-ordination and confidence in theatre. Negative aspects included lack of haptic feedback, and facility for laparoscopic port placement training. Time restriction emerged as the main barrier to training. Despite positive perceptions of training, no trainee completed more than two-thirds of the modules of a self-directed laparoscopic VR training programme. Suggested improvements to the integration of future laparoscopic VR training include an additional theoretical component with a fuller understanding of benefits of VR training, and scheduled supervision. Ultimately, the success of a laparoscopic VR simulation training programme might only be improved if it is a mandatory component of the curriculum, together with dedicated time for training. Future multi-centred implementation studies of validated laparoscopic VR curricula are required. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

  1. Dynamics of the Human Structural Connectome Underlying Working Memory Training. (United States)

    Caeyenberghs, Karen; Metzler-Baddeley, Claudia; Foley, Sonya; Jones, Derek K


    Brain region-specific changes have been demonstrated with a variety of cognitive training interventions. The effect of cognitive training on brain subnetworks in humans, however, remains largely unknown, with studies limited to functional networks. Here, we used a well-established working memory training program and state-of-the art neuroimaging methods in 40 healthy adults (21 females, mean age 26.5 years). Near and far-transfer training effects were assessed using computerized working memory and executive function tasks. Adaptive working memory training led to improvement on (non)trained working memory tasks and generalization to tasks of reasoning and inhibition. Graph theoretical analysis of the structural (white matter) network connectivity ("connectome") revealed increased global integration within a frontoparietal attention network following adaptive working memory training compared with the nonadaptive group. Furthermore, the impact on the outcome of graph theoretical analyses of different white matter metrics to infer "connection strength" was evaluated. Increased efficiency of the frontoparietal network was best captured when using connection strengths derived from MR metrics that are thought to be more sensitive to differences in myelination (putatively indexed by the [quantitative] longitudinal relaxation rate, R1) than previously used diffusion MRI metrics (fractional anisotropy or fiber-tracking recovered streamlines). Our findings emphasize the critical role of specific microstructural markers in providing important hints toward the mechanisms underpinning training-induced plasticity that may drive working memory improvement in clinical populations. This is the first study to explore training-induced changes in the structural connectome using a well-controlled design to examine cognitive training with up-to-date neuroimaging methods. We found changes in global integration based on white matter connectivity within a frontoparietal attention network

  3. Development of a Simulated Environment for Human-Robot Interaction

    Directory of Open Access Journals (Sweden)

    Karsten Berns


    Full Text Available Human-robot interaction scenarios are extremely complicated and require precise definition of the environment variables for rigorously testing different aspects of robotic behavior. The environmental setup affects the behaviors of both the humans and the robots, as they respond differently under varying accoustic or lightning conditions. Moreover, conducting several experiments repeatedly with the humans as test subjects also causes behavioral changes in them and eventually the responses remain no longer similar to the already conducted experiments. Thus making it is impossible to perform interaction scenarios in a repeatable manner. Developing and using 3D simulations, where different parameters can be adjusted, is the most beneficial solution in such cases. This requires not only the development of different simulated robots but also the simulation of dynamic surroundings including the interaction partner. In this paper, we present a simulation framework that allows the simulation of human-robot interaction including the simulated interaction partner and its dynamics.

  4. Simulation training for medical emergencies in the dental setting using an inexpensive software application. (United States)

    Kishimoto, N; Mukai, N; Honda, Y; Hirata, Y; Tanaka, M; Momota, Y


    Every dental provider needs to be educated about medical emergencies to provide safe dental care. Simulation training is available with simulators such as advanced life support manikins and robot patients. However, the purchase and development costs of these simulators are high. We have developed a simulation training course on medical emergencies using an inexpensive software application. The purpose of this study was to evaluate the educational effectiveness of this course. Fifty-one dental providers participated in this study from December 2014 to March 2015. Medical simulation software was used to simulate a patient's vital signs. We evaluated participants' ability to diagnose and treat vasovagal syncope or anaphylaxis with an evaluation sheet and conducted a questionnaire before and after the scenario-based simulation training. The median evaluation sheet score for vasovagal syncope increased significantly from 7/9 before to 9/9 after simulation training. The median score for anaphylaxis also increased significantly from 8/12 to 12/12 (P simulation training. This simulation course improved participants' ability to diagnose and treat medical emergencies and improved their confidence. This course can be offered inexpensively using a software application. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  5. The Relationship of Endoscopic Proficiency to Educational Expense for Virtual Reality Simulator Training Amongst Surgical Trainees. (United States)

    Raque, Jessica; Goble, Adam; Jones, Veronica M; Waldman, Lindsey E; Sutton, Erica


    With the introduction of Fundamentals of Endoscopic Surgery, training methods in flexible endoscopy are being augmented with simulation-based curricula. The investment for virtual reality simulators warrants further research into its training advantage. Trainees were randomized into bedside or simulator training groups (BED vs SIM). SIM participated in a proficiency-based virtual reality curriculum. Trainees' endoscopic skills were rated using the Global Assessment of Gastrointestinal Endoscopic Skills (GAGES) in the patient care setting. The number of cases to reach 90 per cent of the maximum GAGES score and calculated costs of training were compared. Nineteen residents participated in the study. There was no difference in the average number of cases required to achieve 90 per cent of the maximum GAGES score for esophagogastroduodenoscopy, 13 (SIM) versus11 (BED) (P = 0.63), or colonoscopy 21 (SIM) versus 4 (BED) (P = 0.34). The average per case cost of training for esophagogastroduodenoscopy was $35.98 (SIM) versus $39.71 (BED) (P = 0.50), not including the depreciation costs associated with the simulator ($715.00 per resident over six years). Use of a simulator appeared to increase the cost of training without accelerating the learning curve or decreasing faculty time spent in instruction. The importance of simulation in endoscopy training will be predicated on more cost-effective simulators.

  6. Use of Simulation in Canadian Neonatal-Perinatal Medicine Training Programs. (United States)

    Wong, Jonathan; Finan, Emer; Campbell, Douglas


    Introduction Simulation is used for the delivery of education and on occasion assessment. Before such a tool is used routinely in neonatal training programs across Canada, a need assessment is required to determine its current usage by accredited training programs. Our aim was to characterize the type of simulation modalities used and the perceived simulation-based training needs in Canadian neonatal-perinatal medicine (NPM) training programs. Methods A 22-item and 13-item online descriptive survey was sent to all NPM program directors and fellows in Canada, respectively. The survey was modeled on a previously validated tool by Johnston, et al. and responses were collected over 30 days. Results In total, eight (63%) program directors and 24 (28%) fellows completed the survey, with all respondents indicating that simulation is being used. Both lab-based and in situ simulations are occurring, with a range of simulation modalities employed to primarily teach resuscitation, procedural and communication skills. Fellows indicated that simulation should also be used to also teach other important topics, including disease-specific management, crisis resource management, and prevention of medical error. Five (63%) programs have faculty with formal simulation training and four (50%) programs have at least one faculty involved in simulation research. Conclusion Simulation is widely used in Canadian NPM training programs, with program directors and fellows identifying this as an important tool. Simulation can be used to teach a range of skills, but programs need to align their curriculum with both training objectives and learner needs. There is an opportunity for faculty development and increased simulation research.

  7. An analysis of airline landing flare data based on flight and training simulator measurements (United States)

    Heffley, R. K.; Schulman, T. M.; Clement, T. M.


    Landings by experienced airline pilots transitioning to the DC-10, performed in flight and on a simulator, were analyzed and compared using a pilot-in-the-loop model of the landing maneuver. By solving for the effective feedback gains and pilot compensation which described landing technique, it was possible to discern fundamental differences in pilot behavior between the actual aircraft and the simulator. These differences were then used to infer simulator fidelity in terms of specific deficiencies and to quantify the effectiveness of training on the simulator as compared to training in flight. While training on the simulator, pilots exhibited larger effective lag in commanding the flare. The inability to compensate adequately for this lag was associated with hard or inconsistent landings. To some degree this deficiency was carried into flight, thus resulting in a slightly different and inferior landing technique than exhibited by pilots trained exclusively on the actual aircraft.

  8. Faculty Development for Simulation Programs: Five Issues for the Future of Debriefing Training. (United States)

    Cheng, Adam; Grant, Vincent; Dieckmann, Peter; Arora, Sonal; Robinson, Traci; Eppich, Walter


    Debriefing is widely recognized as a critically important element of simulation-based education. Simulation educators obtain and/or seek debriefing training from various sources, including workshops at conferences, simulation educator courses, formal fellowships in debriefings, or through advanced degrees. Although there are many options available for debriefing training, little is known about how faculty development opportunities should be structured to maintain and enhance the quality of debriefing within simulation programs. In this article, we discuss 5 key issues to help shape the future of debriefing training for simulation educators, specifically the following: (1) Are we teaching the appropriate debriefing methods? (2) Are we using the appropriate methods to teach debriefing skills? (3) How can we best assess debriefing effectiveness? (4) How can peer feedback of debriefing be used to improve debriefing quality within programs? (5) How can we individualize debriefing training opportunities to the learning needs of our educators?

  10. Shear stress mediates endothelial adaptations to exercise training in humans. (United States)

    Tinken, Toni M; Thijssen, Dick H J; Hopkins, Nicola; Dawson, Ellen A; Cable, N Timothy; Green, Daniel J


    Although episodic changes in shear stress have been proposed as the mechanism responsible for the effects of exercise training on the vasculature, this hypothesis has not been directly addressed in humans. We examined brachial artery flow-mediated dilation, an index of NO-mediated endothelial function, in healthy men in response to an acute bout of handgrip exercise and across an 8-week period of bilateral handgrip training. Shear stress responses were attenuated in one arm by cuff inflation to 60 mm Hg. Similar increases were observed in grip strength and forearm volume and girth in both limbs. Acute bouts of handgrip exercise increased shear rate (P<0.005) and flow-mediated dilation percentage (P<0.05) in the uncuffed limb, whereas no changes were evident in the cuffed arm. Handgrip training increased flow-mediated dilation percentage in the noncuffed limb at weeks 2, 4, and 6 (P<0.001), whereas no changes were observed in the cuffed arm. Brachial artery peak reactive hyperemia, an index of resistance artery remodeling, progressively increased with training in the noncuffed limb (P<0.001 and 0.004); no changes were evident in the cuffed arm. Neither acute nor chronic shear manipulation during exercise influenced endothelium-independent glyceryl trinitrate responses. These results demonstrate that exercise-induced changes in shear provide the principal physiological stimulus to adaptation in flow-mediated endothelial function and vascular remodeling in response to exercise training in healthy humans.

  11. The Role of Ultrasound Simulation in Obstetrics and Gynecology Training: A UK Trainees' Perspective. (United States)

    Patel, Hersha; Chandrasekaran, Dhivya; Myriokefalitaki, Eva; Gebeh, Alpha; Jones, Kate; Jeve, Yadava B


    Ultrasonography is a core skill required by all obstetrics and gynecology trainees; however, training opportunities in clinical ultrasound are declining. Simulation ultrasound training has been proposed as a strategy to overcome this.The study aims were to determine the current availability of clinical and simulation ultrasound training in obstetrics and gynecology in the United Kingdom and to explore the trainees' perspective on the role of ultrasound simulation. All obstetrics and gynecology trainees within the East Midlands Local Education Training Board in the United Kingdom were asked to complete an anonymous web-based survey in July 2014. Of 140 trainees, 70 (50%) responded to the survey, and 69% reported rarely having dedicated clinical ultrasound sessions. Fifty percent had failed to achieve ultrasound competencies required for their stage of training, and 83% felt that the pressures of service provision limited their exposure to clinical ultrasound.Seventy-three percent of the trainees considered ultrasound simulation to be an essential component of training, and 69% agreed that it would help improve their clinical skills. Only 50% had access to an ultrasound simulator. Seventy-seven percent of the trainees thought that it would be useful to have ultrasound simulation integrated into training. Trainees are struggling to achieve minimal ultrasound competences with clinical ultrasound training alone. They believe that ultrasound simulation will shorten the learning curve and improve their clinical skills and knowledge. Despite the cost implications of simulation training, we propose that consideration is given to formal integration of ultrasound simulation into the curriculum as a possible way forward.

  12. A pilot study of surgical training using a virtual robotic surgery simulator. (United States)

    Tergas, Ana I; Sheth, Sangini B; Green, Isabel C; Giuntoli, Robert L; Winder, Abigail D; Fader, Amanda N


    Our objectives were to compare the utility of learning a suturing task on the virtual reality da Vinci Skills Simulator versus the da Vinci Surgical System dry laboratory platform and to assess user satisfaction among novice robotic surgeons. Medical trainees were enrolled prospectively; one group trained on the virtual reality simulator, and the other group trained on the da Vinci dry laboratory platform. Trainees received pretesting and post-testing on the dry laboratory platform. Participants then completed an anonymous online user experience and satisfaction survey. We enrolled 20 participants. Mean pretest completion times did not significantly differ between the 2 groups. Training with either platform was associated with a similar decrease in mean time to completion (simulator platform group, 64.9 seconds [P = .04]; dry laboratory platform group, 63.9 seconds [P robotic surgical skills (mean, 4.6) and would attend future training sessions (mean, 4.5). Training on the virtual reality robotic simulator or the dry laboratory robotic surgery platform resulted in significant improvements in time to completion and economy of motion for novice robotic surgeons. Although there was a perception that both simulators improved performance, there was a preference for the virtual reality simulator. Benefits unique to the simulator platform include autonomy of use, computerized performance feedback, and ease of setup. These features may facilitate more efficient and sophisticated simulation training above that of the conventional dry laboratory platform, without loss of efficacy.

  13. Establishment of Next-Generation Neurosurgery Research and Training Laboratory with Integrated Human Performance Monitoring. (United States)

    Bernardo, Antonio


    Quality of neurosurgical care and patient outcomes are inextricably linked to surgical and technical proficiency and a thorough working knowledge of microsurgical anatomy. Neurosurgical laboratory-based cadaveric training is essential for the development and refinement of technical skills before their use on a living patient. Recent biotechnological advances including 3-dimensional (3D) microscopy and endoscopy, 3D printing, virtual reality, surgical simulation, surgical robotics, and advanced neuroimaging have proved to reduce the learning curve, improve conceptual understanding of complex anatomy, and enhance visuospatial skills in neurosurgical training. Until recently, few means have allowed surgeons to obtain integrated surgical and technological training in an operating room setting. We report on a new model, currently in use at our institution, for technologically integrated surgical training and innovation using a next-generation microneurosurgery skull base laboratory designed to recreate the setting of a working operating room. Each workstation is equipped with a 3D surgical microscope, 3D endoscope, surgical drills, operating table with a Mayfield head holder, and a complete set of microsurgical tools. The laboratory also houses a neuronavigation system, a surgical robotic, a surgical planning system, 3D visualization, virtual reality, and computerized simulation for training of surgical procedures and visuospatial skills. In addition, the laboratory is equipped with neurophysiological monitoring equipment in order to conduct research into human factors in surgery and the respective roles of workload and fatigue on surgeons' performance.

    Artifon, Everson L A; Tchekmedyian, Asadur J; Fernandes, Kaie; Artifon, Aline N; Fonseca, Alvaro; Otoch, Jose P


    In recent decades, the traditional teaching model of gastrointestinal endoscopy has been based on the teacher-student tutorial method based on theoretical models. Today, simulators have the advantages of virtual reality. The handling apparatus is similar to that used in clinical practice; it is safe, which allows unlimited use, cost-effective for institutions and with superior performance over other training models. Besides, biological simulators are a viable, accessible and affordable tool to simulate gastrointestinal lesions, allowing training in endoscopy with a high degree of similarity in the endoscopic appearance. In this review, we analyze both models, showing its advantages for the training of the endoscopist of the times.

  19. The German VR Simulation Realism Scale--psychometric construction for virtual reality applications with virtual humans. (United States)

    Poeschl, Sandra; Doering, Nicola


    Virtual training applications with high levels of immersion or fidelity (for example for social phobia treatment) produce high levels of presence and therefore belong to the most successful Virtual Reality developments. Whereas display and interaction fidelity (as sub-dimensions of immersion) and their influence on presence are well researched, realism of the displayed simulation depends on the specific application and is therefore difficult to measure. We propose to measure simulation realism by using a self-report questionnaire. The German VR Simulation Realism Scale for VR training applications was developed based on a translation of scene realism items from the Witmer-Singer-Presence Questionnaire. Items for realism of virtual humans (for example for social phobia training applications) were supplemented. A sample of N = 151 students rated simulation realism of a Fear of Public Speaking application. Four factors were derived by item- and principle component analysis (Varimax rotation), representing Scene Realism, Audience Behavior, Audience Appearance and Sound Realism. The scale developed can be used as a starting point for future research and measurement of simulation realism for applications including virtual humans.

  1. Teaching clinical opioid pharmacology with the Human Patient Simulator. (United States)

    Hassan, Zaki; DiLorenzo, Amy; Sloan, Paul


    Postoperative pain should be aggressively treated to decrease the development of chronic postsurgical pain. There has been an increase in the use of Human Patient Simulator (HPS) for teaching advanced courses in pharmacology to medical students, residents, and nurses. The aim of this educational investigation was to pilot the HPS for the training of medical students and surgical recovery room staff nurses in the pharmacology of opioids for the management of postoperative pain. The computerized HPS mannequin is fully monitored with appropriate displays and includes a voice speaker mounted in the head. Medical students and Postanesthesia care unit nurses, led by faculty in the Department of Anesthesiology in small groups of 4-6, participated in a 2- to 3-hour HPS course on the use of opioids for the management of acute postoperative pain. Trainees were asked to treat the acute and severe postoperative pain of a simulated patient. Opioid effects and side effects (such as respiratory depression) were presented on the mannequin in real time to the participants. Side effects of naloxone to reverse opioid depression were presented as a crisis in real time to the participants. Participants completed a 10-item course evaluation using a 5-point Likert scale (1 = strongly disagree; 5 = strongly agree). Twenty-two nurses and nine medical students completed the HPS opioid pharmacology scenario. Almost all participants rated the HPS course very highly and rated every item as either agree or strongly agree. Most participants agreed that the simulator session improved their understanding of opioid pharmacology including opioid side effects and management of opioid complications. Course participants felt most strongly (median, interquartile range) that the simulator session improved their understanding of naloxone pharmacology (5, 0), simulators serve as a useful teaching tool (5, 0), and that they would be pleased to participate in any additional HPS teaching sessions (5, 0).

    Full Text Available Appropriately trained Human Resources for Health (HRH are key inputs into One Health. ‘… more than 50% of all infectious diseases of humans originate from animals and that, of the emerging diseases about 75% could be traced back to animal origin’ (Rweyemamu et al. 2006. A comprehensive understanding of the social determinants of health, through an appropriate training model for HRH, is a key input. This study aimed to explore if human and veterinary medical schools were using such a model or providing time for this model in their curricula. Specific objectives were to: determine the time that human and veterinary medical schools’ curricula provide for subjects or courses related to the social determinants of health; analyse the curricula contents to establish how they relate to the social determinants of health; and explore how a bio-medical model may influence the graduates’ understanding and practice of One Health. A review of human and veterinary graduate-level medical schools’ curricula in East Africa was performed in April 2013 and May 2013. The findings were: in the curricula, SDH contents for knowledge enhancement about One Health are minimal and that teaching is Germ Theory model-driven and partisan. Out of the total training time for physicians and veterinarians, less than 10% was provided for the social determinants of health-related courses. In conclusion, the curricula and training times provided are inadequate for graduates to fully understand the social determinants of health and their role in One Health. Furthermore, the Germ Theory model that has been adopted addresses secondary causes and is inappropriate. There is a need for more in-depth model. This article suggests that a vicious cycle of ill-health model must be taught.

    Nayahangan, Leizl Joy; Nielsen, Kristina Rue; Albrecht-Beste, Elisabeth; Bachmann Nielsen, Michael; Paltved, Charlotte; Lindorff-Larsen, Karen Gilboe; Nielsen, Bjørn Ulrik; Konge, Lars


    New training modalities such as simulation are widely accepted in radiology; however, development of effective simulation-based training programs is challenging. They are often unstructured and based on convenience or coincidence. The study objective was to perform a nationwide needs assessment to identify and prioritize technical procedures that should be included in a simulation-based curriculum. A needs assessment using the Delphi method was completed among 91 key leaders in radiology. Round 1 identified technical procedures that radiologists should learn. Round 2 explored frequency of procedure, number of radiologists performing the procedure, risk and/or discomfort for patients, and feasibility for simulation. Round 3 was elimination and prioritization of procedures. Response rates were 67 %, 70 % and 66 %, respectively. In Round 1, 22 technical procedures were included. Round 2 resulted in pre-prioritization of procedures. In round 3, 13 procedures were included in the final prioritized list. The three highly prioritized procedures were ultrasound-guided (US) histological biopsy and fine-needle aspiration, US-guided needle puncture and catheter drainage, and basic abdominal ultrasound. A needs assessment identified and prioritized 13 technical procedures to include in a simulation-based curriculum. The list may be used as guide for development of training programs. • Simulation-based training can supplement training on patients in radiology. • Development of simulation-based training should follow a structured approach. • The CAMES Needs Assessment Formula explores needs for simulation training. • A national Delphi study identified and prioritized procedures suitable for simulation training. • The prioritized list serves as guide for development of courses in radiology.

  4. Drive-train simulator for a fuel cell hybrid vehicle (United States)

    Brown, Darren; Alexander, Marcus; Brunner, Doug; Advani, Suresh G.; Prasad, Ajay K.

    The model formulation, development process, and experimental validation of a new vehicle powertrain simulator called LFM (Light, Fast, and Modifiable) are presented. The existing powertrain simulators were reviewed and it was concluded that there is a need for a new, easily modifiable simulation platform that will be flexible and sufficiently robust to address a variety of hybrid vehicle platforms. First, the structure and operating principle of the LFM simulator are presented, followed by a discussion of the subsystems and input/output parameters. Finally, a validation exercise is presented in which the simulator's inputs were specified to represent the University of Delaware's fuel cell hybrid transit vehicle and "driven" using an actual drive cycle acquired from it. Good agreement between the output of the simulator and the physical data acquired by the vehicle's on-board sensors indicates that the simulator constitutes a powerful and reliable design tool.

    Definitive assessment of laparoscopic skill improvement after virtual reality simulator training is best obtained during an actual operation. However, this is impossible in medical students. Therefore, we developed an alternative assessment technique using an augmented reality simulator. Nineteen medical students completed a 6-week training program using a virtual reality simulator (LapSim). The pretest and post-test were performed using an object-positioning module and cholecystectomy on an augmented reality simulator(ProMIS). The mean performance measures between pre- and post-training on the LapSim were compared with a paired t-test. In the object-positioning module, the execution time of the task (P reality simulator improved the operative skills of medical students as objectively evaluated by assessment using an augmented reality simulator instead of an actual operation. We hope that these findings help to establish an effective training program for medical students. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

    Olabe, Jon; Olabe, Javier; Roda, Jose Maria; Sancho, Vidal


    Microsurgical technique and anatomical knowledge require extensive laboratory training. Human cadaver models are especially valuable as they supply a good microsurgical training environment simultaneously providing authentic brain anatomy. We developed the "skull infusion model" as an extension of our previous "brain infusion model" taking it a step further maintaining simplicity but enhancing realism. Four human cadaveric brains donated for educational purposes were explanted at autopsy. The specimens were prepared cannulating carotid and vertebral arteries with plastic tubings, flushed with abundant water and fixed for 1 month in formaldehyde. They were then enclosed with white silk clothing (emulating the dura mater) and inserted into human skulls cut previously into two pieces. Tap water at a flow rate of 10 L/h was infused through the arterial tubings. Diverse microsurgical procedures were performed by two trainees, including craniotomies with microsurgical approaches and techniques such as sylvian fissure exposure, extra-intracranial and intra-intracranial bypass, approaches to the ventricles and choroidal fissure opening. The water infusion fills the arterial system, leaking into the interstitial and cisternal space and finally moistening the whole specimen. This makes vascular microsurgical techniques become extremely realistic, increasing its compliance making manipulations easier and more authentic. Standard microsurgical laboratories frequently have difficulties to work with decapitated human cadaver heads but could have human brains readily available. Using the infusion model and inserting it in a human skull makes the environment much more realistic. Its simplicity and inexpensiveness make it a good alternative for developing microsurgical techniques.

  8. Second Life™: a novel simulation platform for the training of surgical residents. (United States)

    Flowers, Michael G; Aggarwal, Rajesh


    A virtual world is a three-dimensional, computer-generated, simulated environment. Human users create "avatars," or virtual projections of themselves, in order to explore this virtual environment and interact with the objects and structures inside it. Second Life™ is one such virtual world accessible freely via the internet, which has been used to construct a virtual hospital complete with reception areas, changing rooms, offices, and hospital wards. Early pioneering studies have demonstrated the advantages of using virtual worlds in the education of surgical residents in a number of ways, from introductions to the clinical environment, initial patient assessment, and managing adverse outcomes, to gaining informed consent, hospital-wide training, and medical device development.

  9. Peer-assisted communication training: veterinary students as simulated clients and communication skills trainers. (United States)

    Strand, Elizabeth B; Johnson, Beth; Thompson, James


    Mounting research supports the use of peer-assisted learning (PAL) as a teaching method in human and veterinary medicine. PAL can be a cost-efficient educational tool, saving both financial resources and faculty time. This article reviews a PAL model for teaching communication skills to veterinary medical students. In this model, junior veterinary students served as simulated clients for sophomore veterinary students. Details regarding methods of program delivery as well as evaluation data are presented. Differences between two student cohorts who participated in the PAL educational model and their subsequent evaluation results are discussed. Overall, veterinary medical students reported that this approach was beneficial and that the topic was critical to their success as veterinarians. Students also showed improvement in communication knowledge and reported that peer feedback was a strength of the program. Finally, future directions to assess and strengthen the use of PAL for communication training in veterinary medical education are proposed.

    The human hand and its dexterity in grasping and manipulating objects are some of the hallmarks of the human species. For years, anatomic and biomechanical studies have deepened the understanding of the human hand’s functioning and, in parallel, the robotics community has been working on the design of robotic hands capable of manipulating objects with a performance similar to that of the human hand. However, although many researchers have partially studied various aspects, to date there has been no comprehensive characterization of the human hand’s function for grasping and manipulation of

    GI endoscopy simulation-based training augments early clinical performance; however, the optimal manner by which to deliver training is unknown. We aimed to validate a simulation-based structured comprehensive curriculum (SCC) designed to teach technical, cognitive, and integrative competencies in colonoscopy. Single-blinded, randomized, controlled trial. Endoscopic simulation course at an academic hospital. Thirty-three novice endoscopists were allocated to an SCC group or self-regulated learning (SRL) group. The SCC group received a curriculum consisting of 6 hours of didactic lectures and 8 hours of virtual reality simulation-based training with expert feedback. The SRL group was provided a list of desired objectives and was instructed to practice on the simulator for an equivalent time (8 hours). Clinical transfer was assessed during 2 patient colonoscopies using the Joint Advisory Group Direct Observation of Procedural Skills (JAG DOPS) scale. Secondary outcome measures included differences in procedural knowledge, immediate post-training simulation performance, and delayed post-training (4-6 weeks) performance during an integrated scenario test on the JAG DOPS communication and integrated scenario global rating scales. There was no significant difference in baseline or post-training performance on the simulator task. The SCC group performed superiorly during their first and second clinical colonoscopies. Additionally, the SCC group demonstrated significantly better knowledge and colonoscopy-specific performance, communication, and global performance during the integrated scenario. We were unable to measure SRL participants' effort outside of mandatory training. In addition, feedback metrics and number of available simulation cases are limited. These results support integration of endoscopy simulation into a structured curriculum incorporating instructional feedback and complementary didactic knowledge as a means to augment technical, cognitive, and

  12. Simulation training based on observation with minimal participation improves paediatric emergency medicine knowledge, skills and confidence. (United States)

    Bloch, Scott A; Bloch, Amy J


    Simulation is becoming standard during emergency medicine (EM) training. To determine if observation-based simulation with minimal participation improves knowledge, skill performance and confidence, we created and evaluated 12 paediatric emergency medicine (PEM) simulations focusing on the educational value of observation. Thirty-one EM residents participated in 1-2 simulations each and observed multiple others. Scores obtained on a knowledge test presimulation and postsimulation, clinical skills assessed for changes in performance over the course of the study, and confidence questionnaires given presimulation and postsimulation were analysed. Participants' feedback regarding the observation model was also evaluated. Average scores obtained on the knowledge test improved significantly presimulation to postsimulation (36.3% vs 51.4%), and remained consistent postsimulation to 4 months after simulation training (51.4% vs 48.8%). Gain scores for participants who observed >80% of the simulations were significantly higher than for those who observedtraining. All participants rated the training as very useful, and 71% reported that being observed was stressful but beneficial, as clinical emergencies are stressful as well. Using observation with minimal participation as the foundation of simulation training may lead to improvement in observer knowledge, skills and confidence. Observation-based simulation training may also save time and resources, allowing a broader coverage of clinical scenarios than programmes requiring active participation by all learners.

  1. An Approach for the Simulation of Ground and Honed Technical Surfaces for Training Classifiers

    Directory of Open Access Journals (Sweden)

    Sebastian Rief


    Full Text Available Training of neural networks requires large amounts of data. Simulated data sets can be helpful if the data required for the training is not available. However, the applicability of simulated data sets for training neuronal networks depends on the quality of the simulation model used. A simple and fast approach for the simulation of ground and honed surfaces with predefined properties is being presented. The approach is used to generate a diverse data set. This set is then applied to train a neural convolution network for surface type recognition. The resulting classifier is validated on the basis of a series of real measurement data and a classification rate of >85% is achieved. A possible field of application of the presented procedure is the support of measurement technicians in the standard-compliant evaluation of measurement data by suggestion of specific data processing steps, depending on the recognized type of manufacturing process.

  3. A comparison of educational strategies for the acquisition of nursing student's performance and critical thinking: simulation-based training vs. integrated training (simulation and critical thinking strategies). (United States)

    Zarifsanaiey, Nahid; Amini, Mitra; Saadat, Farideh


    There is a need to change the focus of nursing education from traditional teacher-centered training programs to student-centered active methods. The integration of the two active learning techniques will improve the effectiveness of training programs. The objective of this study is to compare the effects of the integrated training (simulation and critical thinking strategies) and simulation-based training on the performance level and critical thinking ability of nursing students. The present quasi-experimental study was performed in 2014 on 40 students who were studying practical nursing principles and skills course in the first half of the academic year in Shiraz University of Medical Sciences. Students were randomly divided into control (n = 20) and experimental (n = 20) groups. After training students through simulation and integrated education (simulation and critical thinking strategies), the students' critical thinking ability and performance were evaluated via the use of California Critical Thinking Ability Questionnaire B (CCTST) and Objective Structured Clinical Examination (OSCE) comprising 10 stations, respectively. The external reliability of the California Critical Thinking questionnaire was reported by Case be between 0.78 and 0.80 and the validity of OSCE was approved by 5 members of the faculty. Furthermore, by using Split Half method (the correlation between odd and even stations), the reliability of the test was approved with correlation coefficient of 0.66. Data were analyzed using t-test and Mann-Whitney test. A significance level of 0.05 was considered to be statistically significant. The mean scores of the experimental group performance level were higher than the mean score of the control group performance level. This difference was statistically significant and students in the experimental group in OSCE stations had significantly higher performance than the control group (P students' performance level was increased by the

  7. The impact of simulation-based teaching on home hemodialysis patient training. (United States)

    Chan, Doris T; Faratro, Rose; Chan, Christopher T


    Simulation has been associated with positive educational benefits in the training of healthcare professionals. It is unknown whether the use of simulation to supplement patient training for home hemodialysis (HHD) will assist in improving a patient's transition to home. We aim to assess the impact of simulation training on home visits, retraining and technique failure. Since February 2013, patients training for HHD are required to dialyze independently in a dedicated training room (innovation room) which simulates a patient's home prior to graduation from the program. We performed a single-center retrospective, observational, cohort study comparing patients who completed training using the innovation room (n = 28) versus historical control (n = 21). The outcome measures were number of home visits, retraining visits and technique failure. Groups were matched for age, gender, race, body mass index and comorbidities. Compared with controls, significantly more cases had a permanent vascular access at the commencement of training (57.1 versus 28.6%, χ(2) P = 0.04). Cases spent a median of 2 days [IQR (1.75)] in the innovation room. Training duration was not statistically different between groups {cases: median 10.0 weeks [IQR (6.0)] versus controls: 11.0 [IQR (4.0)]}. Compared with controls, cases showed a trend towards needing less home visits with no difference in the number of re-training session or technique failure. Simulation-based teaching in NHHD training is associated with a trend to a reduction in the number of home visits but had no effect on the number of re-training sessions or proportion of patients with technique failure.

    Picard, Melissa; Nelson, Rachel; Roebel, John; Collins, Heather; Anderson, M Bret


    To determine the benefit of the addition of low-fidelity simulation-based training to the standard didactic-based training in teaching radiology residents common CT-guided procedures. This was a prospective study involving 24 radiology residents across all years in a university program. All residents underwent standard didactic lecture followed by low-fidelity simulation-based training on three common CT-guided procedures: random liver biopsy, lung nodule biopsy, and drain placement. Baseline knowledge, confidence, and performance assessments were obtained after the didactic session and before the simulation training session. Approximately 2 months later, all residents participated in a simulation-based training session covering all three of these procedures. Knowledge, confidence, and performance data were obtained afterward. These assessments covered topics related to preprocedure workup, intraprocedure steps, and postprocedure management. Knowledge data were collected based on a 15-question assessment. Confidence data were obtained based on a 5-point Likert-like scale. Performance data were obtained based on successful completion of predefined critical steps. There was significant improvement in knowledge (P = .005), confidence (P training to the standard didactic curriculum for all procedures. This study suggests that the addition of low-fidelity simulation-based training to a standard didactic-based curriculum is beneficial in improving resident knowledge, confidence, and tested performance of common CT-guided procedures.

  9. Methodology of Transport Scheme Selection for Metro Trains Using a Combined Simulation-Optimization Model

    Directory of Open Access Journals (Sweden)

    Svetla Dimitrova Stoilova


    Full Text Available A major problem connected with planning the organization of trains in metros is the optimization of the scheme of movement, which determines the routing and the number of trains. In this paper, a combined simulation-optimization model including four steps is proposed. In the first step, the train movement has been simulated in order to study the interval between the trains according to the incoming passenger flows at the stations. The simulation model was elaborated using the ARENA software. The results were validated through experimental observations. Using the results obtained from simulations in the second step the correlation between the observed parameters - the incoming passengers and the interval between trains - has been studied. Recent research has established a non-linear relationship between the interval of movement, incoming passengers at the station and passengers on the platform. The third step defines the variant schemes of transportation. The fourth step presents the optimal choice of transportation of trains in metros based on linear optimization model. The model uses the regression obtained in the second step. The practicability of the combined simulation-optimization model is demonstrated through the case study of Sofia’s metro in two peak periods – morning and evening. The model results and the real situation have been compared. It was found that the model results are similar to the real data for the morning peak period but for the evening peak period it is necessary to increase the number of trains.

    Cai, Jian-liang; Zhang, Yi; Sun, Guo-feng; Li, Ning-chen; Zhang, Xiang-hua; Na, Yan-qun


    To investigate the value of laparoscopic virtual reality simulator in laparoscopic suture ability training of catechumen. After finishing the virtual reality training of basic laparoscopic skills, 26 catechumen were divided randomly into 2 groups, one group undertook advanced laparoscopic skill (suture technique) training with laparoscopic virtual reality simulator (virtual group), another used laparoscopic box trainer (box group). Using our homemade simulations, before grouping and after training, every trainee performed nephropyeloureterostomy under laparoscopy, the running time, anastomosis quality and proficiency were recorded and assessed. For virtual group, the running time, anastomosis quality and proficiency scores before grouping were (98 ± 11) minutes, 3.20 ± 0.41, 3.47 ± 0.64, respectively, after training were (53 ± 8) minutes, 6.87 ± 0.74, 6.33 ± 0.82, respectively, all the differences were statistically significant (all P training were (52 ± 9) minutes, 6.08 ± 0.90, 6.33 ± 0.78, respectively, all the differences also were statistically significant (all P training, the running time and proficiency scores of virtual group were similar to box group (all P > 0.05), however, anstomosis quality scores in virtual group were higher than in box group (P = 0.02). The laparoscopic virtual reality simulator is better than traditional box trainer in advanced laparoscopic suture ability training of catechumen.

    Venail, Frederic; Akkari, Mohamed; Merklen, Fanny; Samson, Jacques; Falinower, Sylvain; Cizeron, Gilles; Mondain, Michel; Puel, Jean-Luc; Mura, Thibault


    Teleotoscopy requires the assistance of telehealth facilitators; but their training requirements remain to be determined. We evaluated the use of an otoscopy simulator to train facilitators to remote otoscopies sent via the Internet using a teleaudiology platform. Neurotologists experts were asked to identify images using the otoscopy simulator and to perform an identification task of significant anatomical landmarks. The experts were asked to repeat those tasks remotely, with the help of facilitators who either received basic training, or no training prior to the experiment. Three experts, three trained facilitators and three untrained facilitators participated in this study. The use of an otoscopy simulator in addition to remote otoscopy yielded a good inter- and intrarater agreement (κ between 0.81-1, and 0.80-0.87, respectively). The accuracy of diagnosis was high on-site (11.7% error) and remotely (0% error). The time required for landmark identification task was not increased when performed remotely with a trained facilitator versus on-site otoscopy (9.3 versus 9.2 s/landmark). Conversely, the lack of training of facilitators increased significantly this time (15.6 s/landmark, p simulator coupled to teleaudiology software can be used to efficiently train both experts and facilitators to perform remote otoscopy.

    Multiple simulation training programs have demonstrated that effective transfer of skills can be attained and applied into a more complex scenario, but evidence regarding transfer to the operating room is limited. To assess junior residents trained with simulation performing an advanced laparoscopic procedure in the OR and compare results to those of general surgeons without simulation training and expert laparoscopic surgeons. Experimental study: After a validated 16-session advanced laparoscopy simulation training program, junior trainees were compared to general surgeons (GS) with no simulation training and expert bariatric surgeons (BS) in performing a stapled jejuno-jejunostomy (JJO) in the OR. Global rating scale (GRS) and specific rating scale scores, operative time and the distance traveled by both hands measured with a tracking device, were assessed. In addition, all perioperative and immediate postoperative morbidities were registered. Ten junior trainees, 12 GS and 5 BS experts were assessed performing a JJO in the OR. All trainees completed the entire JJO in the OR without any takeovers by the BS. Six (50 %) BS takeovers took place in the GS group. Trainees had significantly better results in all measured outcomes when compared to GS with considerable higher GRS median [19.5 (18.8-23.5) vs. 12 (9-13.8) p simulated training program in novice surgical residents to the OR.

  19. Moral imagination in simulation-based communication skills training. (United States)

    Chen, Ruth P


    Clinical simulation is used in nursing education and in other health professional programs to prepare students for future clinical practice. Simulation can be used to teach students communication skills and how to deliver bad news to patients and families. However, skilled communication in clinical practice requires students to move beyond simply learning superficial communication techniques and behaviors. This article presents an unexplored concept in the simulation literature: the exercise of moral imagination by the health professional student. Drawing from the works of Hume, Aristotle and Gadamer, a conceptualization of moral imagination is first provided. Next, this article argues that students must exercise moral imagination on two levels: towards the direct communication exchange before them; and to the representative nature of simulation encounters. Last, the limits of moral imagination in simulation-based education are discussed.

  20. Simulation-Based Training Platforms for Arthroscopy: A Randomized Comparison of Virtual Reality Learning to Benchtop Learning. (United States)

    Middleton, Robert M; Alvand, Abtin; Garfjeld Roberts, Patrick; Hargrove, Caroline; Kirby, Georgina; Rees, Jonathan L


    To determine whether a virtual reality (VR) arthroscopy simulator or benchtop (BT) arthroscopy simulator showed superiority as a training tool. Arthroscopic novices were randomized to a training program on a BT or a VR knee arthroscopy simulator. The VR simulator provided user performance feedback. Individuals performed a diagnostic arthroscopy on both simulators before and after the training program. Performance was assessed using wireless objective motion analysis and a global rating scale. The groups (8 in the VR group, 9 in the BT group) were well matched at baseline across all parameters (P > .05). Training on each simulator resulted in significant performance improvements across all parameters (P training conferred a significant improvement in all parameters when trainees were reassessed on the VR simulator (P training did not confer improvement in performance when trainees were reassessed on the BT simulator (P > .05). BT-trained subjects outperformed VR-trained subjects in all parameters during final assessments on the BT simulator (P trained and BT-trained subjects on final VR simulator wireless objective motion analysis assessment (P > .05). Both simulators delivered improvements in arthroscopic skills. BT training led to skills that readily transferred to the VR simulator. Skills acquired after VR training did not transfer as readily to the BT simulator. Despite trainees receiving automated metric feedback from the VR simulator, the results suggest a greater gain in psychomotor skills for BT training. Further work is required to determine if this finding persists in the operating room. This study suggests that there are differences in skills acquired on different simulators and skills learnt on some simulators may be more transferable. Further work in identifying user feedback metrics that enhance learning is also required. Copyright © 2016 Arthroscopy Association of North America. All rights reserved.

  3. Self-rotations in simulated microgravity: performance effects of strategy training. (United States)

    Stirling, Leia; Newman, Dava; Willcox, Karen


    This research studies reorientation methodologies in a simulated microgravity environment using an experimental framework to reduce astronaut adaptation time and provide for a safety countermeasure during extravehicular activity. There were 20 subjects (10 men, 10 women, mean age of 23.6 +/- 3.5) who were divided into 2 groups, fully trained and minimally trained, which determined the amount of motion strategy training received. Subjects performed a total of 48 rotations about their pitch, roll, and yaw axes in a suspension system that simulated microgravity. In each trial subjects either rotated 90 degrees in pitch, 90 degrees in roll, or 180 degrees in yaw. Experimental measures include subject coordination, performance time, cognitive workload assessments, and qualitative motion control strategies. Subjects in the fully trained group had better initial performance with respect to performance time and workload scores for the pitch and yaw rotations. Further, trained subjects reached a steady-state performance time in fewer trials than those with minimal training. The subjects with minimal training tended to use motions that were common in an Earth environment since no technique was provided. For roll rotations they developed motions that would have led to significant off-axis (pitch and yaw) rotations in a true microgravity environment. We have shown that certain body axes are easier to rotate about than others and that fully trained subjects had an easier time performing the body rotations than the minimally trained subjects. This study has provided the groundwork for the development of an astronaut motion-control training program.

  11. Physiological aspects of altitude training and the use of altitude simulators

    Directory of Open Access Journals (Sweden)

    Ranković Goran


    Full Text Available Altitude training in various forms is widely practiced by athletes and coaches in an attempt to improve sea level endurance. Training at high altitude may improve performance at sea level through altitude acclimatization, which improves oxygen transport and/or utilization, or through hypoxia, which intensifies the training stimulus. This basic physiological aspect allows three training modalities: live high and train high (classic high-altitude training, live low and train high (training through hypoxia, and live high and train low (the new trend. In an effort to reduce the financial and logistical challenges of traveling to high-altitude training sites, scientists and manufactures have developed artificial high-altitude environments, which simulate the hypoxic conditions of moderate altitude (2000-3000 meters. Endurance athletes from many sports have recently started using nitrogen environments, or hypoxic rooms and tents as part of their altitude training programmes. The results of controlled studies on these modalities of high-altitude training, their practical approach, and ethics are summarized.

It is definitely a high-stakes job but, even though the professionals do not go through the intense, focused and demanding training schedule as followed by the other equally risky fields, it doesn't yet require any practical training certification. Simulation was introduced in the aviation field in the early '30s with the "Link Trainer", designed to reproduce the most difficult flying case scenario: landing on an air-carrier. After almost a century, flight simulation is still becoming more sophisticated, while surgical training is slowly starting to fill the gap. The aim of a simulator is to produce an "imitation of the operation of a real-world process or system over time". This short but effective definition explains why simulators are utilised across different fields. There is no doubt that surgeons are continuously undergoing a condition of stress, even in nonthreatening situations, while performing a procedure. This condition adds a relevant variable to surgery, meaning that mastering technical skills is not always equal to "safe surgery". This is why "non-technical skills" (NTS) training should be a part of any simulation based training opportunity and will probably start to be always more part of the Handson Training programs.

  14. Studying distributed cognition of simulation-based team training with DiCoT. (United States)

    Rybing, Jonas; Nilsson, Heléne; Jonson, Carl-Oscar; Bang, Magnus


    Health care organizations employ simulation-based team training (SBTT) to improve skill, communication and coordination in a broad range of critical care contexts. Quantitative approaches, such as team performance measurements, are predominantly used to measure SBTTs effectiveness. However, a practical evaluation method that examines how this approach supports cognition and teamwork is missing. We have applied Distributed Cognition for Teamwork (DiCoT), a method for analysing cognition and collaboration aspects of work settings, with the purpose of assessing the methodology's usefulness for evaluating SBTTs. In a case study, we observed and analysed four Emergo Train System® simulation exercises where medical professionals trained emergency response routines. The study suggests that DiCoT is an applicable and learnable tool for determining key distributed cognition attributes of SBTTs that are of importance for the simulation validity of training environments. Moreover, we discuss and exemplify how DiCoT supports design of SBTTs with a focus on transfer and validity characteristics. Practitioner Summary: In this study, we have evaluated a method to assess simulation-based team training environments from a cognitive ergonomics perspective. Using a case study, we analysed Distributed Cognition for Teamwork (DiCoT) by applying it to the Emergo Train System®. We conclude that DiCoT is useful for SBTT evaluation and simulator (re)design.

  15. Benefits to the Simulation Training Community of a New ANSI Standard for the Exchange of Aero Simulation Models (United States)

    Hildreth, Bruce L.; Jackson, E. Bruce


    The American Institute of Aeronautics Astronautics (AIAA) Modeling and Simulation Technical Committee is in final preparation of a new standard for the exchange of flight dynamics models. The standard will become an ANSI standard and is under consideration for submission to ISO for acceptance by the international community. The standard has some a spects that should provide benefits to the simulation training community. Use of the new standard by the training simulation community will reduce development, maintenance and technical refresh investment on each device. Furthermore, it will significantly lower the cost of performing model updates to improve fidelity or expand the envelope of the training device. Higher flight fidelity should result in better transfer of training, a direct benefit to the pilots under instruction. Costs of adopting the standard are minimal and should be paid back within the cost of the first use for that training device. The standard achie ves these advantages by making it easier to update the aerodynamic model. It provides a standard format for the model in a custom eXtensible Markup Language (XML) grammar, the Dynamic Aerospace Vehicle Exchange Markup Language (DAVE-ML). It employs an existing XML grammar, MathML, to describe the aerodynamic model in an input data file, eliminating the requirement for actual software compilation. The major components of the aero model become simply an input data file, and updates are simply new XML input files. It includes naming and axis system conventions to further simplify the exchange of information.

  16. From Humanizing the Educational Process to Professionally Mobile Specialists Training

    Directory of Open Access Journals (Sweden)

    T. A. Fugelova


    Full Text Available Training professional mobile specialists capable of responding flexibly to dynamic changes in society is considered to be the most important issue of the modern educational system. The paper justifies the idea that technical universities should take responsibility for solving this problem by means of humanization of technical education, which implies reconsidering its values and general notions. For overcoming the technocratic trends, the author recommends to cultivate the value of professionalism in the humanization context.Professionalism is defined by using the «professional service» idea as a «purpose acknowledgment, supertask, even a mission». The main components of the above attitude lie in finding the harmony with the world and its basic values. Therefore, technical universities face the challenge of training people of intelligence with a high moral and business responsibility. The basic value of such a person is regarded as «dedication to the cause» - the constant desire to improve the world and leave behind them- selves something of value to society. For training such specialists, the educational process should provide teachers dialogue and collaboration with students to facilitate the process of self-determination and self-development of the prospective specialists. 

  17. The international forum of ophthalmic simulation: developing a virtual reality training curriculum for ophthalmology. (United States)

    Saleh, George M; Lamparter, Julia; Sullivan, Paul M; O'Sullivan, Fiona; Hussain, Badrul; Athanasiadis, Ioannis; Litwin, Andre S; Gillan, Stewart N


    To investigate the effect of a structured, supervised, cataract simulation programme on ophthalmic surgeons in their first year of training, and to evaluate the level of skill transfer. Trainees with minimal intraocular and simulator experience in their first year of ophthalmology undertook a structured, sequential, customised, virtual reality (VR) cataract training programme developed through the International Forum of Ophthalmic Simulation. A set of one-handed, bimanual, static and dynamic tasks were evaluated before and after the course and scores obtained. Statistical significance was evaluated with the Wilcoxon sign-rank test. The median precourse score of 101.50/400 (IQR 58.75-145.75) was significantly improved after completing the training programme ((postcourse score: 302/400, range: 266.25-343), p<0.001). While improvement was evident and found to be statistically significant in all parameters, greatest improvements were found for capsulorhexis and antitremor training ((Capsulorhexis: precourse score=0/100, range 0-4.5; postcourse score=81/100, range 13-87.75; p=0.002), (antitremor training: precourse score=0/100, range 0-0; postcourse score=80/100, range 60.25-91.50; p=0.001)). Structured and supervised VR training can offer a significant level of skills transfer to novice ophthalmic surgeons. VR training at the earliest stage of ophthalmic surgical training may, therefore, be of benefit.

  18. Student peer teaching in paediatric simulation training is a feasible low-cost alternative for education. (United States)

    Wagner, Michael; Mileder, Lukas P; Goeral, Katharina; Klebermass-Schrehof, Katrin; Cardona, Francesco S; Berger, Angelika; Schmölzer, Georg M; Olischar, Monika


    The World Health Organization recommends regular simulation training to prevent adverse healthcare events. We used specially trained medical students to provide paediatric simulation training to their peers and assessed feasibility, cost and confidence of students who attended the courses. Students at the Medical University of Vienna, Austria were eligible to participate. Students attended two high-fidelity simulation training sessions, delivered by peers, which were videorecorded for evaluation. The attendees then completed questionnaires before and after the training. Associated costs and potential benefits were analysed. From May 2013 to June 2015, 152 students attended the sessions and 57 (37.5%) completed both questionnaires. Satisfaction was high, with 95% stating their peer tutor was competent and 90% saying that peer tutors were well prepared. The attendees' confidence in treating critically ill children significantly improved after training (p training was a feasible and low-cost option that increased the number of medical students who could be trained and increased the self-confidence of the attendees. Satisfaction with the peer tutors was high. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

  19. A mixed reality simulator for feline abdominal palpation training in veterinary medicine. (United States)

    Parkes, Rebecca; Forrest, Neil; Baillie, Sarah


    The opportunities for veterinary students to practice feline abdominal palpation are limited as cats have a low tolerance to being examined. Therefore, a mixed reality simulator was developed to complement clinical training. Two PHANToM premium haptic devices were positioned either side of a modified toy cat. Virtual models of the chest and some abdominal contents were superimposed on the physical model. The haptic properties of the virtual models were set by seven veterinarians; values were adjusted while the simulation was being palpated until the representation was satisfactory. Feedback from the veterinarians was encouraging suggesting that the simulator has a potential role in student training.

    Wang, Cong; Jiang, Lan; Wang, Feng; Li, Xin; Yuan, Yanping; Xiao, Hai; Tsai, Hai-Lung; Lu, Yongfeng


    A real-time and real-space time-dependent density functional is applied to simulate the nonlinear electron-photon interactions during shaped femtosecond laser pulse train ablation of diamond. Effects of the key pulse train parameters such as the pulse separation, spatial/temporal pulse energy distribution and pulse number per train on the electron excitation and energy absorption are discussed. The calculations show that photon-electron interactions and transient localized electron dynamics can be controlled including photon absorption, electron excitation, electron density, and free electron distribution by the ultrafast laser pulse train.

  1. Simulation-based crisis resource management training for pediatric critical care medicine: a review for instructors. (United States)

    Cheng, Adam; Donoghue, Aaron; Gilfoyle, Elaine; Eppich, Walter


    To review the essential elements of crisis resource management and provide a resource for instructors by describing how to use simulation-based training to teach crisis resource management principles in pediatric acute care contexts. A MEDLINE-based literature source. OUTLINE OF REVIEW: This review is divided into three main sections: Background, Principles of Crisis Resource Management, and Tools and Resources. The background section provides the brief history and definition of crisis resource management. The next section describes all the essential elements of crisis resource management, including leadership and followership, communication, teamwork, resource use, and situational awareness. This is followed by a review of evidence supporting the use of simulation-based crisis resource management training in health care. The last section provides the resources necessary to develop crisis resource management training using a simulation-based approach. This includes a description of how to design pediatric simulation scenarios, how to effectively debrief, and a list of potential assessment tools that instructors can use to evaluate crisis resource management performance during simulation-based training. Crisis resource management principles form the foundation for efficient team functioning and subsequent error reduction in high-stakes environments such as acute care pediatrics. Effective instructor training is required for those programs wishing to teach these principles using simulation-based learning. Dissemination and integration of these principles into pediatric critical care practice has the potential for a tremendous impact on patient safety and outcomes.

    Ahlborg, Liv; Weurlander, Maria; Hedman, Leif; Nisel, Henry; Lindqvist, Pelle G; Felländer-Tsai, Li; Enochsson, Lars


    This study aimed to explore the value of individualized feedback on performance, flow and self-efficacy during simulated laparoscopy. Furthermore, we wished to explore attitudes towards feedback and simulator training among medical students. Sixteen medical students were included in the study and randomized to laparoscopic simulator training with or without feedback. A teacher provided individualized feedback continuously throughout the procedures to the target group. Validated questionnaires and scales were used to evaluate self-efficacy and flow. The Mann-Whitney U test was used to evaluate differences between groups regarding laparoscopic performance (instrument path length), self-efficacy and flow. Qualitative data was collected by group interviews and interpreted using inductive thematic analyses. Sixteen students completed the simulator training and questionnaires. Instrument path length was shorter in the feedback group (median 3.9 m; IQR: 3.3-4.9) as compared to the control group (median 5.9 m; IQR: 5.0-8.1), pfeedback group were more concentrated on the task and also more anxious. Both groups had high ambitions to succeed and also expressed the importance of getting feedback. The authenticity of the training scenario was important for the learning process. This study highlights the importance of individualized feedback during simulated laparoscopy training. The next step is to further optimize feedback and to transfer standardized and individualized feedback from the simulated setting to the operating room.

  3. Laparoscopic training model using fresh human cadavers without the establishment of penumoperitoneum. (United States)

    Imakuma, Ernesto Sasaki; Ussami, Edson Yassushi; Meyer, Alberto


    Laparoscopy is a well-established alternative to open surgery for treating many diseases. Although laparoscopy has many advantages, it is also associated with disadvantages, such as slow learning curves and prolonged operation time. Fresh frozen cadavers may be an interesting resource for laparoscopic training, and many institutions have access to cadavers. One of the main obstacles for the use of cadavers as a training model is the difficulty in introducing a sufficient pneumoperitoneum to distend the abdominal wall and provide a proper working space. The purpose of this study was to describe a fresh human cadaver model for laparoscopic training without requiring a pneumoperitoneum. A fake abdominal wall device was developed to allow for laparoscopic training without requiring a pneumoperitoneum in cadavers. The device consists of a table-mounted retractor, two rail clamps, two independent frame arms, two adjustable handle and rotating features, and two frames of the abdominal wall. A handycam is fixed over a frame arm, positioned and connected through a USB connection to a television and dissector; scissors and other laparoscopic materials are positioned inside trocars. The laparoscopic procedure is thus simulated. Cadavers offer a very promising and useful model for laparoscopic training. We developed a fake abdominal wall device that solves the limitation of space when performing surgery on cadavers and removes the need to acquire more costly laparoscopic equipment. This model is easily accessible at institutions in developing countries, making it one of the most promising tools for teaching laparoscopy.

  6. Developing an anterior cervical diskectomy and fusion simulator for neurosurgical resident training. (United States)

    Ray, Wilson Z; Ganju, Aruna; Harrop, James S; Hoh, Daniel J


    Surgical simulators are useful in many surgical disciplines to augment residency training. Duty hour restrictions and increasing emphasis on patient safety and attending oversight have changed neurosurgical education from the traditional apprenticeship model. The Congress of Neurological Surgeons Simulation Committee has been developing neurosurgical simulators for the purpose of enhancing resident education and assessing proficiency. To review the initial experience with an anterior cervical diskectomy and fusion (ACDF) simulator. The first ACDF training module was implemented at the 2012 Congress of Neurological Surgeons Annual Meeting. The 90-minute curriculum included a written pretest, didactics, a practical pretest on the simulator, hands-on training, a written posttest, a practical posttest, and postcourse feedback. Didactic material covered clinical indications for ACDF, comparison with other cervical procedures, surgical anatomy and approach, principles of arthrodesis and spinal fixation, and complication management. Written pretests and posttests were administered to assess baseline knowledge and evidence of improvement after the module. Qualitative evaluation of individual performance on the practical (simulator) portion was included. Three neurosurgery residents, 2 senior medical students, and 1 attending neurosurgeon participated in the course. The pretest scores were an average 9.2 (range, 6-13). Posttest scores improved to 11.0 (range, 9-13; P = .03). Initial experience with the ACDF simulator suggests that it may represent a meaningful training module for residents. Simulation will be an important training modality for residents to practice surgical technique and for teachers to assess competency. Further development of an ACDF simulator and didactic curriculum will require additional verification of simulator validity and reliability.

  7. The impact of stress factors in simulation-based laparoscopic training. (United States)

    Andreatta, Pamela B; Hillard, Miranda; Krain, Lewis P


    This study aimed to quantify learner reactions manifesting from a realistic contextual stressor while training with a laparoscopic simulator, and to identify learner-derived stress-modifying behaviors. Stress factors are known to affect cognitive and psychomotor performance. Simulation-based medical training typically occurs in environments that are relatively stress free compared with the applied context. Training is most effective when it occurs in a highly faithful context, so the inclusion of typical clinical stressors in simulated laparoscopic learning environments may be beneficial. Preclinical medical students (N = 27) completed tasks using a laparoscopic simulator under the following 2 conditions: faculty direct observation (stressor) and unobserved (no stressor). The data included simulator performance, blood pressure, real-time heart rates, videotaped behavior, and pre/post surveys of latent anxiety and stress factors associated with participating in the research (eg, STAI 9). Physiologic and behavioral manifestations of stress were observed for all participants during the stressor condition and during poor performance on simulator tasks. Stress was highest during periods of poor performance under the stressor condition. Focusing on the task itself mitigated stress reactions and improved performance on the simulator. Stress reactions can be induced in a laboratory setting where simulation-based training occurs. Stressors imposed on the learner during simulation-based training may help support the acquisition of stress management skills that are necessary in the applied clinical setting. A ramped-up sequence of acquiring technical skills and clinical decision making, followed by stress management techniques, may lead to a more efficient transfer of learning from the simulated context to the clinical area.

  8. Current state of virtual reality simulation in robotic surgery training: a review. (United States)

    Bric, Justin D; Lumbard, Derek C; Frelich, Matthew J; Gould, Jon C


    Worldwide, the annual number of robotic surgical procedures continues to increase. Robotic surgical skills are unique from those used in either open or laparoscopic surgery. The acquisition of a basic robotic surgical skill set may be best accomplished in the simulation laboratory. We sought to review the current literature pertaining to the use of virtual reality (VR) simulation in the acquisition of robotic surgical skills on the da Vinci Surgical System. A PubMed search was conducted between December 2014 and January 2015 utilizing the following keywords: virtual reality, robotic surgery, da Vinci, da Vinci skills simulator, SimSurgery Educational Platform, Mimic dV-Trainer, and Robotic Surgery Simulator. Articles were included if they were published between 2007 and 2015, utilized VR simulation for the da Vinci Surgical System, and utilized a commercially available VR platform. The initial search criteria returned 227 published articles. After all inclusion and exclusion criteria were applied, a total of 47 peer-reviewed manuscripts were included in the final review. There are many benefits to utilizing VR simulation for robotic skills acquisition. Four commercially available simulators have been demonstrated to be capable of assessing robotic skill. Three of the four simulators demonstrate the ability of a VR training curriculum to improve basic robotic skills, with proficiency-based training being the most effective training style. The skills obtained on a VR training curriculum are comparable with those obtained on dry laboratory simulation. The future of VR simulation includes utilization in assessment for re-credentialing purposes, advanced procedural-based training, and as a warm-up tool prior to surgery.

  9. Update on simulation-based surgical training and assessment in ophthalmology: a systematic review. (United States)

    Thomsen, Ann Sofia S; Subhi, Yousif; Kiilgaard, Jens Folke; la Cour, Morten; Konge, Lars


    This study reviews the evidence behind simulation-based surgical training of ophthalmologists to determine (1) the validity of the reported models and (2) the ability to transfer skills to the operating room. Simulation-based training is established widely within ophthalmology, although it often lacks a scientific basis for implementation. We conducted a systematic review of trials involving simulation-based training or assessment of ophthalmic surgical skills among health professionals. The search included 5 databases (PubMed, EMBASE, PsycINFO, Cochrane Library, and Web of Science) and was completed on March 1, 2014. Overall, the included trials were divided into animal, cadaver, inanimate, and virtual-reality models. Risk of bias was assessed using the Cochrane Collaboration's tool. Validity evidence was evaluated using a modern validity framework (Messick's). We screened 1368 reports for eligibility and included 118 trials. The most common surgery simulated was cataract surgery. Most validity trials investigated only 1 or 2 of 5 sources of validity (87%). Only 2 trials (48 participants) investigated transfer of skills to the operating room; 4 trials (65 participants) evaluated the effect of simulation-based training on patient-related outcomes. Because of heterogeneity of the studies, it was not possible to conduct a quantitative analysis. The methodologic rigor of trials investigating simulation-based surgical training in ophthalmology is inadequate. To ensure effective implementation of training models, evidence-based knowledge of validity and efficacy is needed. We provide a useful tool for implementation and evaluation of research in simulation-based training. Copyright © 2015 American Academy of Ophthalmology. Published by Elsevier Inc.

  10. Procedural specificity in laparoscopic simulator training: protocol for a randomised educational superiority trial. (United States)

    Bjerrum, Flemming; Sorensen, Jette Led; Konge, Lars; Lindschou, Jane; Rosthøj, Susanne; Ottesen, Bent; Strandbygaard, Jeanett


    The use of structured curricula for minimally invasive surgery training is becoming increasingly popular. However, many laparoscopic training programs still use basic skills and isolated task training, despite increasing evidence to support the use of training models with higher functional resemblance, such as whole procedural modules. In contrast to basic skills training, procedural training involves several cognitive skills such as elements of planning, movement integration, and how to avoid adverse events. The objective of this trial is to investigate the specificity of procedural practice in laparoscopic simulator training. A randomised single-centre educational superiority trial. Participants are 96 surgical novices (medical students) without prior laparoscopic experience. Participants start by practicing a series of basic skills tasks to a predefined proficiency level on a virtual reality laparoscopy simulator. Upon reaching proficiency, the participants are randomised to either the intervention group, which practices two procedures (an appendectomy followed by a salpingectomy) or to the control group, practicing only one procedure (a salpingectomy) on the simulator. 1:1 central randomisation is used and participants are stratified by sex and time to complete the basic skills. Data collection is done at a surgical skills centre.The primary outcome is the number of repetitions required to reach a predefined proficiency level on the salpingectomy module. The secondary outcome is the total training time to proficiency. The improvement in motor skills and effect on cognitive load are also explored. The results of this trial might provide new knowledge on how the technical part of surgical training curricula should be comprised in the future. To examine the specificity of practice in procedural simulator training is of great importance in order to develop more comprehensive surgical curricula. NCT02069951.

  11. A simulation and training environment for robotic radiosurgery

    Energy Technology Data Exchange (ETDEWEB)

    Schlaefer, Alexander [University of Luebeck, Institute for Robotics and Cognitive Systems, Luebeck (Germany); Stanford University, Department of Radiation Oncology, Stanford, CA (United States); Gill, Jakub; Schweikard, Achim [University of Luebeck, Institute for Robotics and Cognitive Systems, Luebeck (Germany)


    To provide a software environment for simulation of robotic radiosurgery, particularly to study the effective robot workspace with respect to the treatment plan quality, and to illustrate the concepts of robotic radiosurgery. A simulation environment for a robotic radiosurgery system was developed using Java and Java3D. The kinematics and the beam characteristics were modeled and linked to a treatment planning module. Simulations of different robot workspace parameters for two example radiosurgical patient cases were performed using the novel software tool. The first case was an intracranial lesion near the left inner ear, the second case was a spinal lesion. The planning parameters for both cases were visualized with the novel simulation environment. An incremental extension of the robot workspace had limited effect for the intracranial case, where the original workspace already covered the left side of the patient. For the spinal case, a larger workspace resulted in a noticeable improvement in plan quality and a large portion of the beams being delivered from the extended workspace. The new software environment is useful to simulate and analyze parameters and configurations for robotic radiosurgery. An enlarged robot workspace may result in improved plan quality depending on the location of the target region. (orig.)

  12. Porcine cadaver organ or virtual-reality simulation training for laparoscopic cholecystectomy: a randomized, controlled trial. (United States)

    Van Bruwaene, Siska; Schijven, Marlies P; Napolitano, Daniel; De Win, Gunter; Miserez, Marc


    As conventional laparoscopic procedural training requires live animals or cadaver organs, virtual simulation seems an attractive alternative. Therefore, we compared the transfer of training for the laparoscopic cholecystectomy from porcine cadaver organs vs virtual simulation to surgery in a live animal model in a prospective randomized trial. After completing an intensive training in basic laparoscopic skills, 3 groups of 10 participants proceeded with no additional training (control group), 5 hours of cholecystectomy training on cadaver organs (= organ training) or proficiency-based cholecystectomy training on the LapMentor (= virtual-reality training). Participants were evaluated on time and quality during a laparoscopic cholecystectomy on a live anaesthetized pig at baseline, 1 week (= post) and 4 months (= retention) after training. All research was performed in the Center for Surgical Technologies, Leuven, Belgium. In total, 30 volunteering medical students without prior experience in laparoscopy or minimally invasive surgery from the University of Leuven (Belgium). The organ training group performed the procedure significantly faster than the virtual trainer and borderline significantly faster than control group at posttesting. Only 1 of 3 expert raters suggested significantly better quality of performance of the organ training group compared with both the other groups at posttesting (p virtual trainer group did not outperform the control group at any time. For trainees who are proficient in basic laparoscopic skills, the long-term advantage of additional procedural training, especially on a virtual but also on the conventional organ training model, remains to be proven.

  13. Simulation-Based Training - Evaluation of the Course Concept "Laparoscopic Surgery Curriculum" by the Participants. (United States)

    Köckerling, Ferdinand; Pass, Michael; Brunner, Petra; Hafermalz, Matthias; Grund, Stefan; Sauer, Joerg; Lange, Volker; Schröder, Wolfgang


    The learning curve in minimally invasive surgery is much longer than in open surgery. This is thought to be due to the higher demands made on the surgeon's skills. Therefore, the question raised at the outset of training in laparoscopic surgery is how such skills can be acquired by undergoing training outside the bounds of clinical activities to try to shorten the learning curve. Simulation-based training courses are one such model. In 2011, the surgery societies of Germany adopted the "laparoscopic surgery curriculum" as a recommendation for the learning content of systematic training courses for laparoscopic surgery. The curricular structure provides for four 2-day training courses. These courses offer an interrelated content, with each course focusing additionally on specific topics of laparoscopic surgery based on live operations, lectures, and exercises carried out on bio simulators. Between 1st January, 2012 and 31st March, 2016, a total of 36 training courses were conducted at the Vivantes Endoscopic Training Center in accordance with the "laparoscopic surgery curriculum." The training courses were attended by a total of 741 young surgeons and were evaluated as good to very good during continuous evaluation by the participants. Training courses based on the "laparoscopic surgery curriculum" for acquiring skills in laparoscopy are taken up and positively evaluated by young surgeons.

  14. Colonoscopy procedure simulation: virtual reality training based on a real time computational approach. (United States)

    Wen, Tingxi; Medveczky, David; Wu, Jackie; Wu, Jianhuang


    Colonoscopy plays an important role in the clinical screening and management of colorectal cancer. The traditional 'see one, do one, teach one' training style for such invasive procedure is resource intensive and ineffective. Given that colonoscopy is difficult, and time-consuming to master, the use of virtual reality simulators to train gastroenterologists in colonoscopy operations offers a promising alternative. In this paper, a realistic and real-time interactive simulator for training colonoscopy procedure is presented, which can even include polypectomy simulation. Our approach models the colonoscopy as thick flexible elastic rods with different resolutions which are dynamically adaptive to the curvature of the colon. More material characteristics of this deformable material are integrated into our discrete model to realistically simulate the behavior of the colonoscope. We present a simulator for training colonoscopy procedure. In addition, we propose a set of key aspects of our simulator that give fast, high fidelity feedback to trainees. We also conducted an initial validation of this colonoscopic simulator to determine its clinical utility and efficacy.

  15. [Design and validation of a simulator for training in continuous circular capsulotomy for phacoemulsification]. (United States)

    Abellán, E; Calles-Vázquez, M C; Cadarso, L; Sánchez, F M; Usón, J


    To design and validate a simulator for learning and training in the capsulorhexis technique. The system consists of a methacrylate support inclined 15° for the surgeon's hand, an area of commercially available aluminum foil, and another one of similar characteristics, where the student performs the technique through some slots that are previously made in the support. In order to evaluate the feasibility of this simulator, data were collected from 65 ophthalmologists performing the technique during training activities. The ophthalmologists were randomly divided into one group of 30 specialists who start their learning on the eyes of an animal cadaver, and into another of 35 specialists who previously started with this simulator. A simulator is developed for training in the capsulorhexis technique. The students from the simulator group achieved a reduction in the use of cadaver eyes, and a higher efficiency in correct capsulorhexis, unlike the group who started directly on the cadaver eyes. This simulator is an innovation in training of the capsulorhexis technique as regards simplicity, cost, and reuse, as compared to other virtual simulators with more expensive computer equipment (CE) equipment that are more difficult to transport. It is an important step prior to the use of cadaver parts and experimental animals, decreasing the number of both, and therefore the teaching costs.

  16. Simulating Humans as Integral Parts of Spacecraft Missions (United States)

    Bruins, Anthony C.; Rice, Robert; Nguyen, Lac; Nguyen, Heidi; Saito, Tim; Russell, Elaine


    The Collaborative-Virtual Environment Simulation Tool (C-VEST) software was developed for use in a NASA project entitled "3-D Interactive Digital Virtual Human." The project is oriented toward the use of a comprehensive suite of advanced software tools in computational simulations for the purposes of human-centered design of spacecraft missions and of the spacecraft, space suits, and other equipment to be used on the missions. The C-VEST software affords an unprecedented suite of capabilities for three-dimensional virtual-environment simulations with plug-in interfaces for physiological data, haptic interfaces, plug-and-play software, realtime control, and/or playback control. Mathematical models of the mechanics of the human body and of the aforementioned equipment are implemented in software and integrated to simulate forces exerted on and by astronauts as they work. The computational results can then support the iterative processes of design, building, and testing in applied systems engineering and integration. The results of the simulations provide guidance for devising measures to counteract effects of microgravity on the human body and for the rapid development of virtual (that is, simulated) prototypes of advanced space suits, cockpits, and robots to enhance the productivity, comfort, and safety of astronauts. The unique ability to implement human-in-the-loop immersion also makes the C-VEST software potentially valuable for use in commercial and academic settings beyond the original space-mission setting.

  18. Simulation in Otolaryngology: A teaching and training tool. (United States)

    Thone, Natalie; Winter, Matías; García-Matte, Raimundo J; González, Claudia

    Simulation in medical education is an effective method of teaching and learning, allowing standardisation of the learning and teaching processes without compromising the patient. Different types of simulation exist within subspecialty areas of Otolaryngology. Models that have been developed include phantom imaging, dummy patients, virtual models and animal models that are used to teach and practice different skills. Each model has advantages and disadvantages, where virtual reality is an emerging model with a promising future. However, there is still a need for further development of simulation in the area of Otolaryngology.

  19. Building intelligence in third-generation training and battle simulations (United States)

    Jacobi, Dennis; Anderson, Don; von Borries, Vance; Elmaghraby, Adel; Kantardzic, Mehmed; Ragade, Rammohan


    Current war games and simulations are primarily attrition based, and are centered on the concept of force on force. They constitute what can be defined as "second generation" war games. So-called "first generation" war games were focused on strategy with the primary concept of mind on mind. We envision "third generation" war games and battle simulations as concentrating on effects with the primary concept being system on system. Thus the third generation systems will incorporate each successive generation and take into account strategy, attrition and effects. This paper will describe the principal advantages and features that need to be implemented to create a true "third generation" battle simulation and the architectural issues faced when designing and building such a system. Areas of primary concern are doctrine, command and control, allied and coalition warfare, and cascading effects. Effectively addressing the interactive effects of these issues is of critical importance. In order to provide an adaptable and modular system that will accept future modifications and additions with relative ease, we are researching the use of a distributed Multi-Agent System (MAS) that incorporates various artificial intelligence methods. The agent architecture can mirror the military command structure from both vertical and horizontal perspectives while providing the ability to make modifications to doctrine, command structures, inter-command communications, as well as model the results of various effects upon one another, and upon the components of the simulation. This is commonly referred to as "cascading effects," in which A affects B, B affects C and so on. Agents can be used to simulate units or parts of units that interact to form the whole. Even individuals can eventually be simulated to take into account the affect to key individuals such as commanders, heroes, and aces. Each agent will have a learning component built in to provide "individual intelligence" based on

  20. Why Simulation-Based Team Training Has Not Been Used Effectively and What Can Be Done about It (United States)

    Masiello, Italo


    Advanced medical education simulators are broadly used today to train both technical/procedural and team-based skills. While there is convincing evidence of the benefits of training technical skills, this is not the case for team-based skills. Research on medical expertise could drive the creation of a new regime of simulation-based team training.…

  1. Computer-Based Simulation in Blended Learning Curriculum for Hazardous Waste Site Worker Health and Safety Training. (United States)

    West, Cheryl; Slatin, Craig; Sanborn, Wayne; Volicer, Beverly


    Intended for the interest of individuals and organizations who provide adult/worker training and education, we present a discussion of a computer-based simulation training tool used as part of a hazardous waste site worker health and safety training curriculum. Our objective is to present the simulation's development, implementation, and assessment for learning utility from both trainee and trainer perspectives. The simulation is blended with other curriculum components of training courses and supports small group learning. Assessment included end-of-course trainee questionnaires and trainer focus groups to addressing simulation utility as a user-oriented learning tool. A majority of trainees reported simulation trainings as useful learning tools with numerous advantages that support a participatory, blended learning curriculum, and raise awareness of potential work site risks and hazards. Trainers reported that the simulation advanced training impact. Evaluation results indicate that the simulation successfully supports small group learning activities.

  2. Human movement training with a cable driven ARm EXoskeleton (CAREX). (United States)

    Mao, Ying; Jin, Xin; Gera Dutta, Geetanjali; Scholz, John P; Agrawal, Sunil K


    In recent years, the authors have proposed lightweight exoskeleton designs for upper arm rehabilitation using multi-stage cable-driven parallel mechanism. Previously, the authors have demonstrated via experiments that it is possible to apply "assist-as-needed" forces in all directions at the end-effector with such an exoskeleton acting on an anthropomorphic machine arm. A human-exoskeleton interface was also presented to show the feasibility of CAREX on human subjects. The goals of this paper are to 1) further address issues when CAREX is mounted on human subjects, e.g., generation of continuous cable tension trajectories 2) demonstrate the feasibility and effectiveness of CAREX on movement training of healthy human subjects and a stroke patient. In this research, CAREX is rigidly attached to an arm orthosis worn by human subjects. The cable routing points are optimized to achieve a relatively large "tensioned" static workspace. A new cable tension planner based on quadratic programming is used to generate continuous cable tension trajectory for smooth motion. Experiments were carried out on eight healthy subjects. The experimental results show that CAREX can help the subjects move closer to a prescribed circular path using the force fields generated by the exoskeleton. The subjects also adapt to the path shortly after training. CAREX was also evaluated on a stroke patient to test the feasibility of its use on patients with neural impairment. The results show that the patient was able to move closer to a prescribed straight line path with the "assist-as-needed" force field.

  3. Mannequin or standardized patient: participants' assessment of two training modalities in trauma team simulation

    Directory of Open Access Journals (Sweden)

    Wisborg Torben


    Full Text Available Abstract Background Trauma team training using simulation has become an educational compensation for a low number of severe trauma patients in 49 of Norway's 50 trauma hospitals for the last 12 years. The hospitals' own simple mannequins have been employed, to enable training without being dependent on expensive and advanced simulators. We wanted to assess the participants' assessment of using a standardized patient instead of a mannequin. Methods Trauma teams in five hospitals were randomly exposed to a mannequin or a standardized patient in two consecutive simulations for each team. In each hospital two teams were trained, with opposite order of simulation modality. Anonymous, written questionnaires were answered by the participants immediately after each simulation. The teams were interviewed as a focus group after the last simulation, reflecting on the difference between the two simulation modalities. Outcome measures were the participants' assessment of their own perceived educational outcome and comparison of the models, in addition to analysis of the interviews. Results Participants' assessed their educational outcome to be high, and unrelated to the order of appearance of patient model. There were no differences in assessment of realism and feeling of embarrassment. Focus groups revealed that the participants felt that the choice between educational modalities should be determined by the simulated case, with high interaction between team and patient being enhanced by a standardized patient. Conclusion Participants' assessment of the outcome of team training seems independent of the simulation modality when the educational goal is training communication, co-operation and leadership within the team.

  5. Optimization of Simulation and Moulage in Military-Related Medical Training. (United States)

    Petersen, Christopher; Rush, Stephen C; Gallo, Isabelle; Dalere, Bryan; Staak, Brian; Moore, Litt; Kerr, Win; Chandler, Matthew; Smith, Will

    Preparation of Special Operations Forces (SOF) Medics as first responders for the battle space and austere environments is critical to optimize survival and quality of life for our Operators who may sustain serious and complex wounding patterns and illnesses. In the absence of constant clinical exposure for these medics, it is necessary to maximize all available training opportunities. The incorporation of scenario-based training helps weave together teamwork and the ability to practice treatment protocols in a tactical, controlled training environment to reproduce, to some degree, the environment in and stressors under which care will need to be delivered. We reviewed the evolution of training scenarios within one Pararescue (PJ) team since 2008 and codified various tools used to simulate physical findings and drive medical exercises as part of scenario-based training. We also surveyed other SOF Medic training resources. 2017.

  6. A framework-based approach to designing simulation-augmented surgical education and training programs. (United States)

    Cristancho, Sayra M; Moussa, Fuad; Dubrowski, Adam


    The goal of simulation-based medical education and training is to help trainees acquire and refine the technical and cognitive skills necessary to perform clinical procedures. When designers incorporate simulation into programs, their efforts should be in line with training needs, rather than technology. Designers of simulation-augmented surgical training programs, however, face particular problems related to identifying a framework that guides the curricular design activity to fulfill the particular requirements of such training programs. These problems include the lack of (1) an objective identification of training needs, (2) a systematic design methodology to match training objectives with simulation resources, (3) structured assessments of performance, and (4) a research-centered view to evaluate and validate systematically the educational effectiveness of the program. In this report, we present a process called "Aim - FineTune - FollowThrough" to enable the connection of the identified problems to solutions, using frameworks from psychology, motor learning, education and experimental design.

    Full Text Available ABSTRACT OBJECTIVE: Engage the UNIFESP Cardiovascular Surgery residents in coronary anastomosis, assess their skills and certify results, using the Arroyo Anastomosis Simulator and UNIFESP surgical models. METHODS: First to 6th year residents attended a weekly program of technical training in coronary anastomosis, using 4 simulation models: 1. Arroyo simulator; 2. Dummy with a plastic heart; 3. Dummy with a bovine heart; and 4. Dummy with a beating pig heart. The assessment test was comprised of 10 items, using a scale from 1 to 5 points in each of them, creating a global score of 50 points maximum. RESULTS: The technical performance of the candidate showed improvement in all items, especially manual skill and technical progress, critical sense of the work performed, confidence in the procedure and reduction of the time needed to perform the anastomosis after 12 weeks practice. In response to the multiplicity of factors that currently influence the cardiovascular surgeon training, there have been combined efforts to reform the practices of surgical medical training. CONCLUSION: 1 - The four models of simulators offer a considerable contribution to the field of cardiovascular surgery, improving the skill and dexterity of the surgeon in training. 2 - Residents have shown interest in training and cooperate in the development of innovative procedures for surgical medical training in the art.

  8. Optimization of competency in obstetrical emergencies: a role for simulation training. (United States)

    Monod, Cécile; Voekt, Cora A; Gisin, Martina; Gisin, Stefan; Hoesli, Irene M


    In obstetrical emergency situations, optimal management requires the immediate coordinated actions of a multi-disciplinary and multi-professional team. This study investigated the influence of simulation training on four specific skills: self-confidence, handling of emergency situation, knowledge of algorithms and team communication. Clinical algorithms were first presented to the participants. Training for six emergency situations (shoulder dystocia, postpartum haemorrhage, pre-eclampsia, maternal basic life support, neonatal resuscitation and operative vaginal birth) was performed using high- and low-fidelity simulation mannequins. General impression of the simulation training and the four above-mentioned skills were evaluated anonymously through a self-assessment questionnaire with a five-point Likert scale immediately after the training and 3 months later. From November 2010 to March 2012, 168 participants, distributed over six one-day courses, took part in the training. 156 participants returned the questionnaire directly after the course (92.9 %). The questionnaire return rate after 3 months was 36.3 %. The participants gave higher Likert scale answers for the questions on the four specific skills after 3 months compared to immediately after the course. The improvement was statistically significant (p ≤ 0.05) except for the question regarding team communication. Implementation of simulation training strengthens the professional competency.

  12. A simulator for training in endovascular aneurysm repair: The use of three dimensional printers. (United States)

    Torres, I O; De Luccia, N


    To develop an endovascular aneurysm repair (EVAR) simulation system using three dimensional (3D) printed aneurysms, and to evaluate the impact of patient specific training prior to EVAR on the surgical performance of vascular surgery residents in a university hospital in Brazil. This was a prospective, controlled, single centre study. During 2015, the aneurysms of patients undergoing elective EVAR at São Paulo University Medical School were 3D printed and used in training sessions with vascular surgery residents. The 3D printers Stratasys-Connex 350, Formlabs-Form1+, and Makerbot were tested. Ten residents were enrolled in the control group (five residents and 30 patients in 2014) or the training group (five residents and 25 patients in 2015). The control group performed the surgery under the supervision of a senior vascular surgeon (routine procedure, without simulator training). The training group practised the surgery in a patient specific simulator prior to the routine procedure. Objective parameters were analysed, and a subjective questionnaire addressing training utility and realism was answered. Patient specific training reduced fluoroscopy time by 30% (mean 48 min, 95% confidence interval [CI] 40-58 vs. 33 min, 95% CI 26-42 [p 3D printers Form1+ (using flexible resin) and Makerbot (using silicone) provided the best performance based on simulator quality and cost. An EVAR simulation system using 3D printed aneurysms was feasible. The best results were obtained with the 3D printers Form1+ (using flexible resin) and Makerbot (using silicone). Patient specific training prior to EVAR at a university hospital in Brazil improved residents' surgical performance (based on fluoroscopy time, surgery time, and volume of contrast used) and increased their self confidence.

  13. Predoctoral Dental Students' Perceptions of Dental Implant Training: Effect of Preclinical Simulation and Clinical Experience. (United States)

    Prasad, Soni; Bansal, Naveen


    The aims of this study were to assess 1) differences in perceptions of dental implant training between dental students who received didactic training alone (control group) and those who received didactic plus simulation training (test group); 2) differences in response between students with and without clinical experience in implant dentistry; and 3) the interaction effect of simulation training and clinical experience on students' satisfaction. A survey was distributed to the control group in 2014 and to the test group in 2015; both groups were at the same U.S. dental school. Data were collected on confidence levels with various implant restorative procedures along with overall satisfaction and number of implant restorations performed by each student. The response rate was 78.7% in the control group and 81.3% in the test group. In the control group, 85.7% of students reported being satisfied with implant training compared to 90.8% of students in the test group. The interaction effect of simulation training and clinical experience on overall student satisfaction was OR=1.5 at 95% CI: 0.8, 3.0. The students who had clinical experience with implant restorative procedures had significantly greater satisfaction than those who did not (OR=4.8, 95% CI: 2.1, 11.1, pstudents' confidence and satisfaction levels with implant education: they were almost five times more satisfied with implant training when clinical experience in implant restorative procedures was a part of their implant education.

    Ciporen, Jeremy; Gillham, Haley; Noles, Michele; Dillman, Dawn; Baskerville, Mark; Haley, Caleb; Spight, Donn; Turner, Ryan C; Lucke-Wold, Brandon P


    Simulation training has been shown to be an effective teaching tool. Learner management of an intraoperative crisis such as a major cerebrovascular bleed requires effective teamwork, communication, and implementation of key skill sets at appropriate time points. This study establishes a first of a kind simulation experience in a neurosurgery/anesthesia resident (learners) team working together to manage an intraoperative crisis. Using a cadaveric cavernous carotid injury perfusion model, 7 neurosurgery and 6 anesthesia learners, were trained on appropriate vascular injury management using an endonasal endoscopic technique. Learners were evaluated on communication skills, crisis management algorithms, and implementation of appropriate skill sets at the right time. A preanatomic and postanatomic examination and postsimulation survey was administered to neurosurgery learners. Anesthesia learners provided posttraining evaluation through a tailored realism and teaching survey. Neurosurgery learners' anatomic examination score improved from presimulation (33.89%) to postsimulation (86.11%). No significant difference between learner specialties was observed for situation awareness, decision making, communications and teamwork, or leadership evaluations. Learners reported the simulation realistic, beneficial, and highly instructive. Realistic, first of kind, clinical simulation scenarios were presented to a neurosurgery/anesthesia resident team who worked together to manage an intraoperative crisis. Learners were effectively trained on crisis management, the importance of communication, and how to develop algorithms for future implementation in difficult scenarios. Learners were highly satisfied with the simulation training experience and requested that it be integrated more consistently into their residency training programs.

  15. Simulation-based multidisciplinary team training decreases time to critical operations for trauma patients. (United States)

    Murphy, Margaret; Curtis, Kate; Lam, Mary K; Palmer, Cameron S; Hsu, Jeremy; McCloughen, Andrea


    Simulation has been promoted as a platform for training trauma teams. However, it is not clear if this training has an impact on health service delivery and patient outcomes. This study evaluates the association between implementation of a simulation based multidisciplinary trauma team training program at a metropolitan trauma centre and subsequent patient outcomes. This was a retrospective review of trauma registry data collected at an 850-bed Level 1 Adult Trauma Centre in Sydney, Australia. Two concurrent four-year periods, before and after implementation of a simulation based multidisciplinary trauma team training program were compared for differences in time to critical operations, Emergency Department (ED) length of stay (LOS) and patient mortality. There were 2389 major trauma patients admitted to the hospital during the study, 1116 in the four years preceding trauma team training (the PREgroup) and 1273 in the subsequent 4 years (the POST group). There were no differences between the groups with respect to gender, body region injured, incidence of polytrauma, and pattern of arrival to ED. The POST group was older (median age 54 versus 43 years, p team training was associated with a reduction in time to critical operation while overall ED length of stay increased. Simulation is promoted as a platform for training teams; but the complexity of trauma care challenges efforts to demonstrate direct links between multidisciplinary team training and improved outcomes. There remain considerable gaps in knowledge as to how team training impacts health service delivery and patient outcomes.

  17. Cultural Respect Encompassing Simulation Training: Being Heard About Health Through Broadband. (United States)

    Min-Yu Lau, Phyllis; Woodward-Kron, Robyn; Livesay, Karen; Elliott, Kristine; Nicholson, Patricia


    Cultural Respect Encompassing Simulation Training (CREST) is a learning program that uses simulation to provide health professional students and practitioners with strategies to communicate sensitively with culturally and linguistically diverse (CALD) patients. It consists of training modules with a cultural competency evaluation framework and CALD simulated patients to interact with trainees in immersive simulation scenarios. The aim of this study was to test the feasibility of expanding the delivery of CREST to rural Australia using live video streaming; and to investigate the fidelity of cultural sensitivity - defined within the process of cultural competency which includes awareness, knowledge, skills, encounters and desire - of the streamed simulations. In this mixed-methods evaluative study, health professional trainees were recruited at three rural academic campuses and one rural hospital to pilot CREST sessions via live video streaming and simulation from the city campus in 2014. Cultural competency, teaching and learning evaluations were conducted. Forty-five participants rated 26 reliable items before and after each session and reported statistically significant improvement in 4 of 5 cultural competency domains, particularly in cultural skills (Pcommunication training and the quality of the simulation training provided remotely by CREST. Cultural sensitivity education using live video-streaming and simulation can contribute to health professionals' learning and is effective in improving cultural competency. CREST has the potential to be embedded within health professional curricula across Australian universities to address issues of health inequalities arising from a lack of cultural sensitivity training. Significance for public healthThere are significant health inequalities for migrant populations. They commonly have poorer access to health services and poorer health outcomes than the Australian-born population. The factors are multiple, complex and

    Dilaveri, C A; Szostek, J H; Wang, A T; Cook, D A


    Breast and pelvic examinations are challenging intimate examinations. Technology-based simulation may help to overcome these challenges. To synthesise the evidence regarding the effectiveness of technology-based simulation training for breast and pelvic examination. Our systematic search included MEDLINE, EMBASE, CINAHL, PsychINFO, Scopus, and key journals and review articles; the date of the last search was January 2012. Original research studies evaluating technology-enhanced simulation of breast and pelvic examination to teach learners, compared with no intervention or with other educational activities. The reviewers evaluated study eligibility and abstracted data on methodological quality, learners, instructional design, and outcomes, and used random-effects models to pool weighted effect sizes. In total, 11 272 articles were identified for screening, and 22 studies were eligible, enrolling 2036 trainees. In eight studies comparing simulation for breast examination training with no intervention, simulation was associated with a significant improvement in skill, with a pooled effect size of 0.86 (95% CI 0.52-1.19; P < 0.001). Four studies comparing simulation training for pelvic examination with no intervention had a large and significant benefit, with a pooled effect size of 1.18 (95% CI 0.40-1.96; P = 0.003). Among breast examination simulation studies, dynamic models providing feedback were associated with improved outcomes. In pelvic examination simulation studies, the addition of a standardised patient to the simulation model and the use of an electronic model with enhanced feedback improved outcomes. In comparison with no intervention, breast and pelvic examination simulation training is associated with moderate to large effects for skills outcomes. Enhanced feedback appears to improve learning. © 2013 RCOG.

    To compare the impact of virtual reality simulation training and theoretical teaching on the ability of inexperienced trainees to produce adequate virtual transvaginal ultrasound images. We conducted a randomized controlled trial with parallel groups. Participants included inexperienced residents starting a training program in Paris. The intervention consisted of 40 minutes of virtual reality simulation training using a haptic transvaginal simulator versus 40 minutes of conventional teaching including a conference with slides and videos and answers to the students' questions. The outcome was a 19-point image quality score calculated from a set of 4 images (sagittal and coronal views of the uterus and left and right ovaries) produced by trainees immediately after the intervention, using the same simulator on which a new virtual patient had been uploaded. Experts assessed the outcome on stored images, presented in a random order, 2 months after the trial was completed. They were blinded to group assignment. The hypothesis was an improved outcome in the intervention group. Randomization was 1 to 1. The mean score was significantly greater in the simulation group (n = 16; mean score, 12; SEM, 0.8) than the control group (n = 18; mean score, 9; SEM, 1.0; P= .0302). The quality of virtual vaginal images produced by inexperienced trainees was greater immediately after a single virtual reality simulation training session than after a single theoretical teaching session. © 2015 by the American Institute of Ultrasound in Medicine.

  1. Multidisciplinary In Situ Simulation-Based Training as a Postpartum Hemorrhage Quality Improvement Project. (United States)

    Lutgendorf, Monica A; Spalding, Carmen; Drake, Elizabeth; Spence, Dennis; Heaton, Jason O; Morocco, Kristina V


    Postpartum hemorrhage is a common obstetric emergency affecting 3 to 5% of deliveries, with significant maternal morbidity and mortality. Effective management of postpartum hemorrhage requires strong teamwork and collaboration. We completed a multidisciplinary in situ postpartum hemorrhage simulation training exercise with structured team debriefing to evaluate hospital protocols, team performance, operational readiness, and real-time identification of system improvements. Our objective was to assess participant comfort with managing obstetric hemorrhage following our multidisciplinary in situ simulation training exercise. This was a quality improvement project that utilized a comprehensive multidisciplinary in situ postpartum hemorrhage simulation exercise. Participants from the Departments of Obstetrics and Gynecology, Anesthesia, Nursing, Pediatrics, and Transfusion Services completed the training exercise in 16 scenarios run over 2 days. The intervention was a high fidelity, multidisciplinary in situ simulation training to evaluate hospital protocols, team performance, operational readiness, and system improvements. Structured debriefing was conducted with the participants to discuss communication and team functioning. Our main outcome measure was participant self-reported comfort levels for managing postpartum hemorrhage before and after simulation training. A 5-point Likert scale (1 being very uncomfortable and 5 being very comfortable) was used to measure participant comfort. A paired t test was used to assess differences in participant responses before and after the simulation exercise. We also measured the time to prepare simulated blood products and followed the number of postpartum hemorrhage cases before and after the simulation exercise. We trained 113 health care professionals including obstetricians, midwives, residents, anesthesiologists, nurse anesthetists, nurses, and medical assistants. Participants reported a higher comfort level in managing

    The Dartslab team at NASA's Jet Propulsion Laboratory (JPL) has a long history of developing physics-based simulations based on the Darts/Dshell simulation framework that have been used to simulate many planetary robotic missions, such as the Cassini spacecraft and the rovers that are currently driving on Mars. Recent collaboration efforts between the Dartslab team at JPL and the Mission Operations Directorate (MOD) at NASA Johnson Space Center (JSC) have led to significant enhancements to the Dartslab DSENDS (Dynamics Simulator for Entry, Descent and Surface landing) software framework. The new version of DSENDS is now being used for new planetary mission simulations at JPL. JSC is using DSENDS as the foundation for a suite of software known as COMPASS (Core Operations, Mission Planning, and Analysis Spacecraft Simulation) that is the basis for their new human space mission simulations and analysis. In this paper, we will describe the collaborative process with the JPL Dartslab and the JSC MOD team that resulted in the redesign and enhancement of the DSENDS software. We will outline the improvements in DSENDS that simplify creation of new high-fidelity robotic/spacecraft simulations. We will illustrate how DSENDS simulations are assembled and show results from several mission simulations.

    Uhlig, Thomas; Roshani, Frank-Cyrus; Amodio, Ciro; Rovera, Alessandro; Zekusic, Nikola; Helmholz, Hannes; Fairchild, Matthew


    The current emergency response concept for the International Space Station (ISS) includes the support of the Flight Control Team. Therefore, the team members need to be trained in emergencies and the corresponding crew procedures to ensure a smooth collaboration between crew and ground. In the case where the astronaut and ground personnel training is not collocated it is a challenging endeavor to ensure and maintain proper knowledge and skills for the Flight Control Team. Therefore, a virtual 3D simulator at the Columbus Control Center (Col-CC) is presented, which is used for ground personnel training in the on-board emergency response. The paper briefly introduces the main ISS emergency scenarios and the corresponding response strategy, details the resulting learning objectives for the Flight Controllers and elaborates on the new simulation method, which will be used in the future. The status of the 3D simulator, first experiences and further plans are discussed.

    Despite expanding access to institutional birth in Guatemala, maternal mortality remains largely unchanged over the last ten years. Enhancing the quality of emergency obstetric and neonatal care is one important strategy to decrease mortality. An innovative, low-tech, simulation-based team training program (PRONTO) aims to optimize care provided during obstetric and neonatal emergencies in low-resource settings. We conducted PRONTO simulation training between July 2012 and December 2012 in 15 clinics in Alta Verapaz, Huehuetenango, San Marcos, and Quiche, Guatemala. These clinics received PRONTO as part of a larger pair-matched cluster randomized trial of a comprehensive intervention package. Training participants were obstetric and neonatal care providers that completed pre- and post- training assessments for the two PRONTO training modules, which evaluated knowledge of evidence-based practice and self-efficacy in obstetric and neonatal topics. Part of the training included a session for trained teams to establish strategic goals to improve clinical practice. We utilized a pre/post-test design to evaluate the impact of the course on both knowledge and self-efficacy with longitudinal fixed effects linear regression with robust standard errors. Pearson correlation coefficients were used to assess the correlation between knowledge and self-efficacy. Poisson regression was used to assess the association between the number of goals achieved and knowledge, self-efficacy, and identified facility-level factors. Knowledge and self-efficacy scores improved significantly in all areas of teaching. Scores were correlated for all topics overall at training completion. More than 60 % of goals set to improve clinic functioning and emergency care were achieved. No predictors of goal achievement were identified. PRONTO training is effective at improving provider knowledge and self-efficacy in training areas. Further research is needed to evaluate the impact of the training on

  15. Low cost, high yield: simulation of obstetric emergencies for family medicine training. (United States)

    Magee, Susanna R; Shields, Robin; Nothnagle, Melissa


    Simulation is now the educational standard for emergency training in residency and is particularly useful on a labor and delivery unit, which is often a stressful environment for learners given the frequency of emergencies. However, simulation can be costly. This study aimed to assess the feasibility and effectiveness of low-cost simulated obstetrical emergencies in training family medicine residents. The study took place in a community hospital in an urban underserved setting in the northeast United States. Low-cost simulations were developed for postpartum hemorrhage (PPH) and preeclampsia/eclampsia (PEC). Twenty residents were randomly assigned to the intervention (simulated PPH or PEC followed by debriefing) or control (lecture on PPH or PEC) group, and equal numbers of residents were assigned to each scenario. All participants completed a written test at baseline and an oral exam 6 months later on the respective scenario to which they were assigned. The participants provided written feedback on their respective teaching interventions. We compared performance on pretests and posttests by group using Wilcoxon Rank Sum. Twenty residents completed the study. Both groups performed similarly on baseline tests for both scenarios. Compared to controls, intervention residents scored significantly higher on the examination on the management of PPH but not for PEC. All intervention group participants reported that the simulation training was "extremely useful," and most found it "enjoyable." We demonstrated the feasibility and acceptability of two low-cost obstetric emergency simulations and found that they may result in persistent increases in trainee knowledge.

  16. A Full Scope Nuclear Power Plant Training Simulator: Design and Implementation Experiences

    Directory of Open Access Journals (Sweden)

    Pedro A. Corcuera


    Full Text Available This paper describes the development of a full scope training simulator for a Spanish nuclear power plant. The simulator is based on a client/server architecture that allows the distributed execution in a network with many users to participate in the same simulation. The interface was designed to support the interaction of the operators with the simulator through virtual panels supported by touch screens with high fidelity graphic displays. The simulation environment is described including the extension added to facilitate an easy operation by instructors. The graphical interface has been developed using component software technology. The appropriate selection of hardware for visualization and interaction, in terms of cost and performance, resulted in a facility much less expensive than the classic hard panels replica simulators and, at the same time, able to fulfill most of the training requirements. The main features of the simulator are the distributed execution control of the models and the flexibility of design and maintenance of the interface. The benefits of virtual panels approach are the automatic switch reposition and tagging, configuration flexibility, low maintenance requirements, or capability to support multiple users distributed across the corporate intranet. After exhaustive validation and testing, the training sessions are being conducted successfully.

  18. Otoscopy simulation training in a classroom setting: a novel approach to teaching otoscopy to medical students. (United States)

    Davies, Joel; Djelic, Lucas; Campisi, Paolo; Forte, Vito; Chiodo, Albino


    To determine the effectiveness of using of an otoscopy stimulator to teach medical students the primary principles of otoscopy in large group training sessions and improve their confidence in making otologic diagnoses. Cross-sectional survey design. In March 2013, the Department of Otolaryngology-Head and Neck Surgery held a large-scale otoscopy simulator teaching session at the MaRS Innovation Center for 92 first and second year University of Toronto medical students. Following the training session, students were provided with an optional electronic, nine-question survey related to their experience with learning otoscopy using the simulators alone, and in comparison to traditional methods of teaching. Thirty-four medical students completed the survey. Ninety-one percent of the respondents indicated that the overall quality of the event was either very good or excellent. A total of 71% of respondents either agreed, or strongly agreed, that the otoscopy simulator training session improved their confidence in diagnosing pathologies of the ear. The majority (70%) of students indicated that the training session had stimulated their interest in otolaryngology-head and neck surgery as a medical specialty. Organizing large-group otoscopy simulator training sessions is one method whereby students can become familiar with a wide variety of pathologies of the ear and improve both their diagnostic accuracy and their confidence in making otologic diagnoses.

  19. [Simulation training in pulmonary medicine: Rationale, review of the literature and perspectives]. (United States)

    Hureaux, J; Urban, T


    Training in pulmonary medicine requires the acquisition of a great deal of knowledge, but also technical know-how and interpersonal skills. The prevailing teaching pattern is mentorship. It implies a direct transmission of knowledge, but also entails some drawbacks such as disparity in learning opportunities, subjective evaluation of the trainee and potential risks for patients. There is growing interest in simulation training as a teaching technique, where students practice their skills in a secure environment, then analyse their performance in a debriefing session. It is complementary to other learning methods (abstraction, observation or mentorship) and forms part of an ethical approach: 'never practice on a real patient for the first time'. We have reviewed the literature related to simulation training in pulmonary medicine and in particular for physical examination, technical skills, pathologies, communication with patients and therapeutic education. In most of the studies, simulation training is a way of speeding up students' training - without necessarily yielding better results - and of respecting the procedures. We then present the French regulations and official guidelines regarding the use of this training method in the teaching of medicine. Finally, we shall consider some prospects of this approach for the community of pulmonologists. Copyright © 2015 SPLF. Published by Elsevier Masson SAS. All rights reserved.

    Toubasi, Samar; Alosta, Mohammed R; Darawad, Muhammad W; Demeh, Waddah


    Providing efficient basic life support (BLS) training is crucial for practicing nurses who provide direct patient care. Nevertheless, data addressing the impact of BLS courses on the skills and performance of Jordanian nurses are scarce. This study aimed to assess the effectiveness of a BLS simulation training on Jordanian nurses' skill improvement in cardiopulmonary resuscitation. A prospective quasi-experimental, single group pretest-posttest design was used to study the effect of BLS simulation; using a 9-item checklist; on the spot training; American Heart Association, on a group of Jordanian nurses. A pre-test was conducted following a CPR scenario to test the skills using 9-item checklist extrapolated from the American Heart Association guidelines. After debriefing, an interactive on spot training was provided. Later, participants undertook an unscheduled post-test after four weeks that included the same nine items. Thirty registered nurses with a mean clinical experience of 6.1years participated in the study. Comparing pre-test (M=4.6, SD=2.9, range=0 to 9) with post-test results (M=7.5, SD=1.7, range=4 to 9) showed an overall improvement in skills and BLS scores after the simulation training program (t=7.4, df=29, pskills and performance among Jordanian nurses. A refreshment BLS training session for nurses is highly recommended to guarantee nurses' preparedness in actual CPR scenarios. Copyright © 2015 Elsevier Ltd. All rights reserved.

  1. Dwell Time Modelling and Optimized Simulations for Crowded Rail Transit Lines Based on Train Capacity

    Directory of Open Access Journals (Sweden)

    Zhibin Jiang


    Full Text Available Understanding the nature of rail transit dwell time has potential benefits for both the users and the operators. Crowded passenger trains cause longer dwell times and may prevent some passengers from boarding the first available train that arrives. Actual dwell time and the process of passenger alighting and boarding are interdependent through the sequence of train stops and propagated delays. A comprehensive and feasible dwell time simulation model was developed and optimized to address the problems associated with scheduled timetables. The paper introduces the factors that affect dwell time in urban rail transit systems, including train headway, the process and number of passengers alighting and boarding the train, and the inability of train doors to properly close the first time because of overcrowded vehicles. Finally, based on a time-driven micro-simulation system, Shanghai rail transit Line 8 is used as an example to quantify the feasibility of scheduled dwell times for different stations, directions of travel and time periods, and a proposed dwell time during peak hours in several crowded stations is presented according to the simulation results.

  2. Validation of a new basic virtual reality simulator for training of basic endoscopic skills: the SIMENDO. (United States)

    Verdaasdonk, E G G; Stassen, L P S; Monteny, L J; Dankelman, J


    The aim of this study was to establish content, face, concurrent, and the first step of construct validity of a new simulator, the SIMENDO, in order to determine its usefulness for training basic endoscopic skills. The validation started with an explanation of the goals, content, and features of the simulator (content validity). Then, participants from eight different medical centers consisting of experts (> or =100 laparoscopic procedures performed) and surgical trainees (reality (VR) trainer. Subsequently, they were asked to answer 28 structured questions about the simulator (face validity). Ratings were scored on a scale from 1 (very bad/useless) to 5 (excellent/very useful). Additional comments could be given as well. Furthermore, two experiments were conducted. In experiment 1, aimed at establishing concurrent validity, the training effect of a single-handed hand-eye coordination task in the simulator was compared with a similar task in a conventional box trainer and with the performance of a control group that received no training. In experiment 2 (first step of construct validity), the total score of task time, collisions, and path length of three consecutive runs in the simulator was compared between experts (>100 endoscopic procedures) and novices (no experience). A total of 75 participants (36 expert surgeons and 39 surgical trainees) filled out the questionnaire. Usefulness of tasks, features, and movement realism were scored between a mean value of 3.3 for depth perception and 4.3 for appreciation of training with the instrument. There were no significant differences between the mean values of the scores given by the experts and surgical trainees. In response to statements, 81% considered this VR trainer generally useful for training endoscopic techniques to residents, and 83% agreed that the simulator was useful to train hand-eye coordination. In experiment 1, the training effect for the single-handed task showed no significant difference between the

  4. Mastoidectomy performance assessment of virtual simulation training using final-product analysis. (United States)

    Andersen, Steven A W; Cayé-Thomasen, Per; Sørensen, Mads S


    The future development of integrated automatic assessment in temporal bone virtual surgical simulators calls for validation against currently established assessment tools. This study aimed to explore the relationship between mastoidectomy final-product performance assessment in virtual simulation and traditional dissection training. Prospective trial with blinding. A total of 34 novice residents performed a mastoidectomy on the Visible Ear Simulator and on a cadaveric temporal bone. Two blinded senior otologists assessed the final-product performance using a modified Welling scale. The simulator gathered basic metrics on time, steps, and volumes in relation to the on-screen tutorial and collisions with vital structures. Substantial inter-rater reliability (kappa = 0.77) for virtual simulation and moderate inter-rater reliability (kappa = 0.59) for dissection final-product assessment was found. The simulation and dissection performance scores had significant correlation (P = .014). None of the basic simulator metrics correlated significantly with the final-product score except for number of steps completed in the simulator. A modified version of a validated final-product performance assessment tool can be used to assess mastoidectomy on virtual temporal bones. Performance assessment of virtual mastoidectomy could potentially save the use of cadaveric temporal bones for more advanced training when a basic level of competency in simulation has been achieved.

  5. The Development of A Human Systems Simulation Laboratory: Strategic Direction

    Energy Technology Data Exchange (ETDEWEB)

    Jacques Hugo; Katya le Blanc; David Gertman


    The Human System Simulation Laboratory (HSSL) at the Idaho National Laboratory is one of few facilities of its kind that allows human factors researchers to evaluate various aspects of human performance and human system interaction for proposed reactor designs and upgrades. A basic system architecture, physical configuration and simulation capability were established to enable human factors researchers to support multiple, simultaneous simulations and also different power plant technologies. Although still evolving in terms of its technical and functional architecture, the HSSL is already proving its worth in supporting current and future nuclear industry needs for light water reactor sustainability and small modular reactors. The evolution of the HSSL is focused on continual physical and functional refinement to make it a fully equipped, reconfigurable facility where advanced research, testing and validation studies can be conducted on a wider range of reactor technologies. This requires the implementation of additional plant models to produce empirical research data on human performance with emerging human-system interaction technologies. Additional beneficiaries of this information include system designers and HRA practitioners. To ensure that results of control room crew studies will be generalizable to the existing and evolving fleet of US reactors, future expansion of the HSSL may also include other SMR plant models, plant-specific simulators and a generic plant model aligned to the current generation of pressurized water reactors (PWRs) and future advanced reactor designs. Collaboration with industry partners is also proving to be a vital component of the facility as this helps to establish a formal basis for current and future human performance experiments to support nuclear industry objectives. A long-range Program Plan has been developed for the HSSL to ensure that the facility will support not only the Department of Energy’s Light Water Reactor

  7. SAGRAD: A Program for Neural Network Training with Simulated Annealing and the Conjugate Gradient Method. (United States)

    Bernal, Javier; Torres-Jimenez, Jose


    SAGRAD (Simulated Annealing GRADient), a Fortran 77 program for computing neural networks for classification using batch learning, is discussed. Neural network training in SAGRAD is based on a combination of simulated annealing and Møller's scaled conjugate gradient algorithm, the latter a variation of the traditional conjugate gradient method, better suited for the nonquadratic nature of neural networks. Different aspects of the implementation of the training process in SAGRAD are discussed, such as the efficient computation of gradients and multiplication of vectors by Hessian matrices that are required by Møller's algorithm; the (re)initialization of weights with simulated annealing required to (re)start Møller's algorithm the first time and each time thereafter that it shows insufficient progress in reaching a possibly local minimum; and the use of simulated annealing when Møller's algorithm, after possibly making considerable progress, becomes stuck at a local minimum or flat area of weight space. Outlines of the scaled conjugate gradient algorithm, the simulated annealing procedure and the training process used in SAGRAD are presented together with results from running SAGRAD on two examples of training data.

  8. Validity of Cognitive Load Measures in Simulation-Based Training: A Systematic Review. (United States)

    Naismith, Laura M; Cavalcanti, Rodrigo B


    Cognitive load theory (CLT) provides a rich framework to inform instructional design. Despite the applicability of CLT to simulation-based medical training, findings from multimedia learning have not been consistently replicated in this context. This lack of transferability may be related to issues in measuring cognitive load (CL) during simulation. The authors conducted a review of CLT studies across simulation training contexts to assess the validity evidence for different CL measures. PRISMA standards were followed. For 48 studies selected from a search of MEDLINE, EMBASE, PsycInfo, CINAHL, and ERIC databases, information was extracted about study aims, methods, validity evidence of measures, and findings. Studies were categorized on the basis of findings and prevalence of validity evidence collected, and statistical comparisons between measurement types and research domains were pursued. CL during simulation training has been measured in diverse populations including medical trainees, pilots, and university students. Most studies (71%; 34) used self-report measures; others included secondary task performance, physiological indices, and observer ratings. Correlations between CL and learning varied from positive to negative. Overall validity evidence for CL measures was low (mean score 1.55/5). Studies reporting greater validity evidence were more likely to report that high CL impaired learning. The authors found evidence that inconsistent correlations between CL and learning may be related to issues of validity in CL measures. Further research would benefit from rigorous documentation of validity and from triangulating measures of CL. This can better inform CLT instructional design for simulation-based medical training.

  10. Forward-time simulations of human populations with complex diseases.

    Directory of Open Access Journals (Sweden)

    Bo Peng


    Full Text Available Due to the increasing power of personal computers, as well as the availability of flexible forward-time simulation programs like simuPOP, it is now possible to simulate the evolution of complex human diseases using a forward-time approach. This approach is potentially more powerful than the coalescent approach since it allows simulations of more than one disease susceptibility locus using almost arbitrary genetic and demographic models. However, the application of such simulations has been deterred by the lack of a suitable simulation framework. For example, it is not clear when and how to introduce disease mutants-especially those under purifying selection-to an evolving population, and how to control the disease allele frequencies at the last generation. In this paper, we introduce a forward-time simulation framework that allows us to generate large multi-generation populations with complex diseases caused by unlinked disease susceptibility loci, according to specified demographic and evolutionary properties. Unrelated individuals, small or large pedigrees can be drawn from the resulting population and provide samples for a wide range of study designs and ascertainment methods. We demonstrate our simulation framework using three examples that map genes associated with affection status, a quantitative trait, and the age of onset of a hypothetical cancer, respectively. Nonadditive fitness models, population structure, and gene-gene interactions are simulated. Case-control, sibpair, and large pedigree samples are drawn from the simulated populations and are examined by a variety of gene-mapping methods.

  11. A computer simulation approach to measurement of human control strategy (United States)

    Green, J.; Davenport, E. L.; Engler, H. F.; Sears, W. E., III


    Human control strategy is measured through use of a psychologically-based computer simulation which reflects a broader theory of control behavior. The simulation is called the human operator performance emulator, or HOPE. HOPE was designed to emulate control learning in a one-dimensional preview tracking task and to measure control strategy in that setting. When given a numerical representation of a track and information about current position in relation to that track, HOPE generates positions for a stick controlling the cursor to be moved along the track. In other words, HOPE generates control stick behavior corresponding to that which might be used by a person learning preview tracking.

  12. Towards developing high-fidelity simulated learning environment training modules in audiology. (United States)

    Dzulkarnain, A A; Rahmat, S; Mohd Puzi, N A F; Badzis, M


    This discussion paper reviews and synthesises the literature on simulated learning environment (SLE) from allied health sciences, medical and nursing in general and audiology specifically. The focus of the paper is on discussing the use of high-fidelity (HF) SLE and describing the challenges for developing a HF SLE for clinical audiology training. Through the review of the literature, this paper discusses seven questions, (i) What is SLE? (ii) What are the types of SLEs? (iii) How is SLE classified? (iv) What is HF SLE? (v) What types of SLEs are available in audiology and their level of fidelity? (vi) What are the components needed for developing HF SLE? (vii) What are the possible types of HF SLEs that are suitable for audiology training? Publications were identified by structured searches from three major databases PubMed, Web of Knowledge and PsychInfo and from the reference lists of relevant articles. The authors discussed and mapped the levels of fidelity of SLE audiology training modules from the literature and the learning domains involved in the clinical audiology courses. The discussion paper has highlighted that most of the existing SLE audiology training modules consist of either low- or medium-fidelity types of simulators. Those components needed to achieve a HF SLE for audiology training are also highlighted. Overall, this review recommends that the combined approach of different levels and types of SLE could be used to obtain a HF SLE training module in audiology training.

  13. Metabolites of amygdalin under simulated human digestive fluids. (United States)

    Shim, Soon-Mi; Kwon, Hoonjeong


    In the present study, degradation of amygdalin in the human digestive fluids and absorption of its metabolites by the human small intestine were evaluated by simulating a gastrointestinal digestion model combined with a human intestinal cell culture. Orally administered amygdalin was degraded into prunasin by digestive enzymes after passing through the salivary and gastrointestinal phases. Prunasin, the major metabolite of amygdalin in the digestive fluids, was incubated in a caco-2 cell culture system. Prunasin was degraded into the mandelonitrile by β-glucosidase and then hydroxylated across the small intestinal wall, producing hydroxymandelonitrile (149 Da). Results from this study suggest that risk assessment of amygdalin from food consumption can be done in a more accurate way by determining a pathway of amygdalin metabolism in the simulating human upper gastrointestinal tract.

    The job interview is an important step toward successful employment and often a significant challenge for people with psychiatric disability. Vocational rehabilitation specialists can benefit from a systematic approach to training job interview skills. The investigators teamed up with a company that specializes in creating simulated job interview training to create software that provides a virtual reality experience with which learners can systematically improve their job interview skills, reduce their fears, and increase their confidence about going on job interviews. The development of this software is described and results are presented from a feasibility and tolerability trial with 10 participants with psychiatric disability referred from their vocational service programs. Results indicate that this representative sample had a strongly positive response to the prototype job interview simulation. They found it easy to use, enjoyed the experience, and thought it realistic and helpful. Almost all described the interview as anxiety provoking but that the anxiety lessened as they became more skilled. They saw the benefit of its special features such as ongoing feedback from a "coach in the corner" and from being able to review a transcript of the interview. They believed that they could learn the skills being taught through these methods. Participants were enthusiastic about wanting to use the final product when it becomes available. The advantages of virtual reality technology for training important skills for rehabilitation are discussed.

We report the case of a 20-year-old woman having lost her driver’s license after sustaining a moderate TBI.Objective: We aimed to evaluate the effectiveness of an in-simulator training program with automated feedback on driving performance in a TBI individual.Methods: The participant underwent an initial and a final in-simulator driving assessment and 11 in-simulator training sessions with driving-specific automated feedbacks. Driving performance (simulation duration, speed regulation and lateral positioning was measured in the driving simulator.Results: Speeding duration decreased during training sessions from 1.50 ± 0.80 min (4.16 ± 2.22% to 0.45 ± 0.15 min (0.44 ± 0.42% but returned to initial duration after removal of feedbacks for the final assessment. Proper lateral positioning improved with training and was maintained at the final assessment. Time spent in an incorrect lateral position decreased from 18.85 min (53.61% in the initial assessment to 1.51 min (4.64% on the final assessment.Conclusion: Driving simulators represent an

    The Real Time Modeling Computer (RTMC) is a duplicate implementation of the software from the Savannah River Simulator on an independent hardware system. Such a cloned'' software tool allows a wide range of development and support activities to be undertaken independently of the training simulator complex. In addition to the expected simulator support function provided by the RTMC (e.g., deficiency corrections and development of model enhancements), the facility is also used for engineering analysis scoping studies and to drive an artificial intelligence research laboratory. An application anticipated for the future is its use as a test-bed for a major hardware upgrade of the simulator complex. Finally, the proprietorship of the RTMC by a laboratory group independent of the simulator organization, allows the site to leverage a wide range of technical skills and interests into a simulator support role.

    Full Text Available This paper describes the user interface design for a human-hand simulation system, a virtual environment that produces ground truth data (life-like human hand gestures and animations and provides visualization support for experiments on computer vision-based hand pose estimation and tracking. The system allows users to save time in data generation and easily create any hand gestures. We have designed and implemented this user interface with the consideration of usability goals and software engineering issues.

    Fang, Kerry Y; Bjering, Heidi; Ginige, Athula


    Non-adherence to medication and treatment regimens is considered as a major issue in the healthcare industry as it can lead to negative consequences. Various strategies have been applied to improve adherence, however many of these strategies lack the interaction and personalisation-aspect which has been shown to be crucial to the patients. This paper discusses the importance of personalised interaction in improving patients' medication adherence, and the characteristics needed in an avatar to simulate such human-human interactions.
