Abstract
Importance Intraoperative stressors may compound cognitive load, prompting performance decline and threatening patient safety. However, not all surgeons cope equally well with stress, and the disparity between performance stability and decline under high cognitive demand may be characterized by differences in activation within brain areas associated with attention and concentration such as the prefrontal cortex (PFC). Objective To compare PFC activation between surgeons demonstrating stable performance under temporal stress with those exhibiting stress-related performance decline. Design, Setting, and Participants Cohort study conducted from July 2015 to September 2016 at the Imperial College Healthcare National Health Service Trust, England. One hundred two surgical residents (postgraduate year 1 and greater) were invited to participate, of which 33 agreed to partake. Exposures Participants performed a laparoscopic suturing task under 2 conditions: self-paced (SP; without time-per-knot restrictions), and time pressure (TP; 2-minute per knot time restriction). Main Outcomes and Measures A composite deterioration score was computed based on between-condition differences in task performance metrics (task progression score [arbitrary units], error score [millimeters], leak volume [milliliters], and knot tensile strength [newtons]). Based on the composite score, quartiles were computed reflecting performance stability (quartile 1 [Q1]) and decline (quartile 4 [Q4]). Changes in PFC oxygenated hemoglobin concentration (HbO2) measured at 24 different locations using functional near-infrared spectroscopy were compared between Q1 and Q4. Secondary outcomes included subjective workload (Surgical Task Load Index) and heart rate. Results Of the 33 participants, the median age was 33 years, the range was 29 to 56 years, and 27 were men (82%). The Q1 residents demonstrated task-induced increases in HbO2 across the bilateral ventrolateral PFC (VLPFC) and right dorsolateral PFC in the SP condition and in the VLPFC in the TP condition. In contrast, Q4 residents demonstrated decreases in HbO2 in both conditions. The magnitude of PFC activation (change in HbO2) was significantly greater in Q1 than Q4 across the bilateral VLPFC during both SP (mean [SD] left VLPFC: Q1, 0.44 [1.30] μM; Q4, -0.21 [2.05] μM; P < .001; right VLPFC: Q1, 0.46 [1.12] μM; Q4, -0.15 [2.14] μM; P < .001) and TP (mean [SD] left VLPFC: Q1, 0.44 [1.36] μM; Q4, -0.03 [1.83] μM; P = .001; right VLPFC: Q1, 0.49 [1.70] μM; Q4, -0.32 [2.00] μM; P < .001) conditions. There were no significant between-group differences in Surgical Task Load Index or heart rate in either condition. Conclusions and Relevance Performance stability within TP is associated with sustained prefrontal activation indicative of preserved attention and concentration, whereas performance decline is associated with prefrontal deactivation that may represent task disengagement.

Abstract
OBJECTIVE The current trend toward increasingly integrated technological support systems and the rise of streamlined processes in the OR have led to a growing demand for personnel with higher levels of training. Although simulation systems are widely used and accepted in surgical training, they are practically non-existent for perioperative nursing, especially scrub nursing. This paper describes and evaluates an interactive OR environment simulation to help train scrub nurses. METHODS A system comprising multiple computers and monitors, including an interactive table and a touchscreen combined with a client-server software solution, was designed to simulate a scrub nurse's workplace. The resulting demonstrator was evaluated under laboratory conditions with a multicenter interview study involving three participating ear, nose, and throat (ENT) departments in Germany and Switzerland. RESULTS The participant group of 15 scrub nurses had an average of 12.8 years hands-on experience in the OR. A series of 22 questions was used to evaluate various aspects of the demonstrator system and its suitability for training novices. DISCUSSION The system received very positive feedback. The participants stated that familiarization with instrument names and learning the instrument table setup were the two most important technical topics for beginners. They found the system useful for acquiring these skills as well as certain non-technical aspects. CONCLUSIONS Interactive training through simulation is a new approach for preparing novice scrub nurses for the challenges at the instrument table in the OR. It can also improve the lifelong training of perioperative personnel. The proposed system is currently unique in its kind. It can be used to train both technical and non-technical skills and, therefore, contributes to patient safety. Moreover, it is not dependent on a specific type of surgical intervention or medical discipline.

Abstract
BACKGROUND There is evidence of increased mortality and reduced efficiency in hospitals due to the annual changeover of junior doctors. This paper describes a framework to develop an intensive simulated week that will recreate experiences and situations that junixor surgical interns will likely face in their first weeks after graduation. METHODS To provide evidence-based recommendations, a systematic review of published literature using the keywords 'surg*', 'boot', 'camp' was performed. Reports of the development, implementation or evaluation of a simulated skills course or 'boot camp' to prepare incoming surgical interns were analysed. RESULTS Eighteen relevant articles were identified. Subjects on internship preparation courses have identified 'hands-on' training sessions to be very useful. In particular, mock pages have been identified as being valuable and didactic lectures have been identified as the weakest parts of the course. We first consider the end-users of the course and their associated learning needs. We subsequently discuss resources required and propose a strategy for the organisation of a course and selection of teaching faculty. Finally, we consider the costs involved in running a course. CONCLUSIONS This paper proposes a framework for the development, organisation and implementation of an intensive simulation course to prepare graduating medical students for their role as junior surgical intern. Facilitating the step change in responsibility from student to surgical intern may improve patient safety in addition to reducing the associated anxiety for the clinician.

Abstract
Introduction. Deficiencies in teamwork skills have been shown to contribute to the occurrence of adverse events during surgery. Consequently, several teamwork assessment tools have been developed to evaluate trainee nontechnical performance. This paper aims to provide an overview of these instruments and review the validity of each tool. Furthermore, the present paper aims to review the deficiencies surrounding training and propose several recommendations to address these issues. Methods. A systematic literature search was conducted to identify teamwork assessment tools using MEDLINE (1946 to August 2015), EMBASE (1974 to August 2015), and PsycINFO (1806 to August 2015) databases. Results. Eight assessment tools which encompass aspects of teamwork were identified. The Nontechnical Skills for Surgeons (NOTSS) assessment was found to possess the highest level of validity from a variety of sources; reliability and acceptability have also been established for this tool. Conclusions. Deficits in current surgical training pathways have prompted several recommendations to meet the evolving requirements of surgeons. Recommendations from the current paper include integration of teamwork training and assessment into medical school curricula, standardised formal training of assessors to ensure accurate evaluation of nontechnical skill acquisition, and integration of concurrent technical and nontechnical skills training throughout training.

Abstract
In the last three decades, simulation has become a key tool in the training of doctors and the maintenance of patient safety. Simulation offers an immersive, realistic way of learning technical skills. Recent changes to the training schemes in many surgical specialities mean that the hours spent working between senior house officer and consultant have been reduced. This, combined with other pressures (such as reduced operating hours), means that surgery has moved away from its traditional apprenticeship model and toward a competency-based one. Simulation can be a standardized and safe method for training and assessing surgeons. Use of simulation for training has become significant alongside the development of laparoscopic techniques, and evidence suggests that skills obtained in simulation are applicable in real clinical scenarios. Simulation allows trainees to make mistakes, to ask the "what if?" questions, and to learn and reflect on such situations without risking patient safety. Virtual reality simulators have been used to allow experts to plan complicated operations and assess perioperative risks. Most recently, fully immersive simulations, such as those with whole theater teams involved, and patient-centered simulations allow development of other key skills aside from purely technical ones. Use of simulation in isolation from traditional teaching methods will furnish the surgeon in training with skills, but the best time and place to use such skills comes only with experience. In this article we examine the role of simulation in surgical training and its impact in the context of reduced training time.

Abstract
BACKGROUND The transition from student to intern can be challenging. The "August" or "July effect" describes increased errors and reduced patient safety during this transition. The study objectives were to develop, pilot, and evaluate clinical performance after an immersive simulation course for incoming interns. METHODS Graduating students were recruited for a 1-week immersive simulation course. Controls received no simulation training. Primary outcome (at baseline, and 1 and 6 months) was clinical performance on Objective Structured Clinical Examinations (OSCE) of clinical procedures and surgical technical skills. Secondary outcomes were self-reported confidence and clinical procedure logbook data. RESULTS Nineteen students were recruited. Sixteen completed the 6-month follow-up, 10 in the intervention group and 6 in the control group. No differences were demonstrated between interventions and controls at baseline (OSCE [median, 66 vs. 78; P = .181], technical skills [48 vs. 52.5; P = .381], and confidence [101 vs 96; P = .368]). Interventions outperformed controls at 1 month (OSCE [111 vs 82; P = .001], technical skills [78.5 vs 63; P = .030], and confidence [142 vs. 119; P < .001]), and 6 months (OSCE [107 vs. 93; P = .007], technical skills [92.5 vs. 69; P = .044], and confidence [148 vs. 129; P = .022]). No differences were observed in numbers of clinical procedures performed at 1 (P = .958), 4 (P = .093), or 6 months (P = .713). CONCLUSION The immersive simulation course objectively improved subjects' clinical skills, technical skills, and confidence. Despite similar clinical experience as controls, the intervention group's improved performance persisted at 6 months follow-up. This feasible and effective intervention to ease transition from student to intern could reduce errors and enhance patient safety.

Abstract
BACKGROUND Previous studies on surgical team composition have shown that surgical team size had an independent impact on surgical performance in US and Canadian hospitals. We aimed to investigate the impact of team composition on surgical performance in two Chinese hospitals. METHODS General surgery procedures performed from April 2011 to June 2012 were retrospectively reviewed to record the number of attendees in the operating room (OR) and the procedure time (PT). RESULTS A total of 1,900 valid procedures, mostly laparoscopic, were performed during the study period. The mean PT was 90.5 min. On average, there were a total of 6 (range = 3-8) team members per procedure: 3 (range = 1-5) surgeons, 2 nurses, and 1 anesthesiologist. Unlike the data reported for the US and Canada, the number of nurses and anesthesiologists remained stable in most cases, whereas the number of surgeons differed by procedure. Multiple-regression analysis revealed that both the complexity of the operation and the team size significantly affected PT. When procedure complexity and patient condition were kept constant, adding one team member in our data analysis predicted an increase of 34.7 min in the PT. CONCLUSION The surgical team size has a measurable effect on PT. Aside from surgical complexity, the team composition and member stability affected PT in the OR. Optimizing surgical teams and developing a strategy to maintain team stability are of great importance for improving OR efficiency.

Abstract
Background Foot ulcers are a frequent reason for diabetes-related hospitalisation. Clinical training is known to have a beneficial impact on foot ulcer outcomes. Clinical training using simulation techniques has rarely been used in the management of diabetes-related foot complications or chronic wounds. Simulation can be defined as a device or environment that attempts to replicate the real world. The few non-web-based foot-related simulation courses have focused solely on training for a single skill or "part task" (for example, practicing ingrown toenail procedures on models). This pilot study aimed to primarily investigate the effect of a training program using multiple methods of simulation on participants' clinical confidence in the management of foot ulcers. Methods Sixteen podiatrists participated in a two-day Foot Ulcer Simulation Training (FUST) course. The course included pre-requisite web-based learning modules, practicing individual foot ulcer management part tasks (for example, debriding a model foot ulcer), and participating in replicated clinical consultation scenarios (for example, treating a standardised patient (actor) with a model foot ulcer). The primary outcome measure of the course was participants' pre- and post completion of confidence surveys, using a five-point Likert scale (1 = Unacceptable-5 = Proficient). Participants' knowledge, satisfaction and their perception of the relevance and fidelity (realism) of a range of course elements were also investigated. Parametric statistics were used to analyse the data. Pearson's r was used for correlation, ANOVA for testing the differences between groups, and a paired-sample t-test to determine the significance between pre- and post-workshop scores. A minimum significance level of p < 0.05 was used. Results An overall 42% improvement in clinical confidence was observed following completion of FUST (mean scores 3.10 compared to 4.40, p < 0.05). The lack of an overall significant change in knowledge scores reflected the participant populations' high baseline knowledge and pre-requisite completion of web-based modules. Satisfaction, relevance and fidelity of all course elements were rated highly. Conclusions This pilot study suggests simulation training programs can improve participants' clinical confidence in the management of foot ulcers. The approach has the potential to enhance clinical training in diabetes-related foot complications and chronic wounds in general.

Abstract
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.

Abstract
BACKGROUND In the past 20 years the surgical simulator market has seen substantial growth. Simulators are useful for teaching surgical skills effectively and with minimal harm and discomfort to patients. Before a simulator can be integrated into an educational program, it is recommended that its validity be determined. This study aims to provide a critical review of the literature and the main experiences and efforts relating to the validation of simulators during the last two decades. METHODS Subjective and objective validity studies between 1980 and 2008 were identified by searches in Pubmed, Cochrane, and Web of Science. RESULTS Although several papers have described definitions of various subjective types of validity, the literature does not offer any general guidelines concerning methods, settings, and data interpretation. Objective validation studies on endourological simulators were mainly characterized by a large variety of methods and parameters used to assess validity and in the definition and identification of expert and novice levels of performance. CONCLUSION Validity research is hampered by a paucity of widely accepted definitions and measurement methods of validity. It would be helpful to those considering the use of simulators in training programs if there were consensus on guidelines for validating surgical simulators and the development of training programs. Before undertaking a study to validate a simulator, researchers would be well advised to conduct a training needs analysis (TNA) to evaluate the existing need for training and to determine program requirements in a training program design (TPD), methods that are also used by designers of military simulation programs. Development and validation of training models should be based on a multidisciplinary approach involving specialists (teachers), residents (learners), educationalists (teaching the teachers), and industrial designers (providers of teaching facilities). In addition to technical skills, attention should be paid to contextual, interpersonal, and task-related factors.

Abstract
Teamwork is the cornerstone of rehabilitation medicine. Rehabilitation workers in European countries are well educated in their own disciplines and attain appropriate professional knowledge; however, they lack educational opportunities for acquiring skills and attitudes necessary for effective teamwork, mainly communication, cooperation, and leadership. Consequently, teamwork is compromised and rehabilitation effectiveness reduced. Therefore, training in these components of professional competence needs scaling up in order to increase their impact on rehabilitation care.

Development of an educational simulator system, ECCSIM-Lite, for the acquisition of basic perfusion techniques and evaluation. J Artif Organs 2007; 10:201-5. [PMID: 18071848 DOI: 10.1007/s10047-007-0396-x] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2007] [Accepted: 08/08/2007] [Indexed: 10/22/2022]
Abstract
A training system with quantitative evaluation of performance for training perfusionists is valuable for preparation for rare but critical situations. A simulator system, ECCSIM-Lite, for extracorporeal circulation (ECC) training of perfusionists was developed. This system consists of a computer system containing a simulation program of the hemodynamic conditions and the training scenario with instructions, a flow sensor unit, a reservoir with a built-in water level sensor, and an ECC circuit with a soft bag representing the human body. This system is relatively simple, easy to handle, compact, and reasonably inexpensive. Quantitative information is recorded, including the changes in arterial flow by the manipulation of a knob, the changes in venous drainage by handling a clamp, and the change in reservoir level; the time courses of the above parameters are presented graphically. To increase the realism of the training, a numerical-hydraulic circulatory model was applied. Following the instruction and explanation of the scenario in the form of audio and video captions, it is possible for a trainee to undertake self-study without an instructor or a computer operator. To validate the system, a training session was given to three beginners using a simple training scenario; it was possible to record the performance of the perfusion sessions quantitatively. In conclusion, the ECCSIM-Lite system is expected to be useful for perfusion training, since quantitative information about the trainee's performance is recorded and it is possible to use the data for assessment and comparison.

Abstract
Developments in surgical technology and procedure have accelerated and altered the work carried out in the operating theatre/room, but team modelling and training have not co-evolved. Evidence suggests that team structure and role allocation are sometimes unclear and contentious, and coordination and communication are not fully effective. To improve teamwork, clinicians need models that specify team resources, structure, process and tasks. They also need measures to assess performance and methods to train teamwork strategically. An effective training strategy might be to incorporate teamwork with other technical skills training in simulation. However, the measures employed for enhancing teamwork in training and practice will need to vary in their object of analysis, level of technical specificity, and system scope.

Abstract
BACKGROUND Substantial efforts are focused on the high prevalence of patient harm due to medical errors and the mechanisms to prevent them. The potential role of the medical student as a valuable member of the team in preventing patient harm has, however, often been overlooked. METHODS Four cases are presented from two US academic health centers in which medical students prevented or were in a position to prevent patient harm from occurring. The authors directly participated in each case. RESULTS The types of harm prevented included averting non-sterile conditions, missing medications, mitigating exposure to highly contagious patients, and respecting patients' "do not resuscitate" requests. CONCLUSION Medical students are often overlooked as valuable participants in ensuring patient safety. These cases show that medical students may be an untapped resource for medical error prevention. Medical students should be trained to recognize errors and to speak up when errors occur. Those supervising students should welcome and encourage students to actively communicate observed errors and near misses and should work to eliminate all intimidation by medical hierarchy that can prevent students from being safety advocates.
