High-fidelity simulation

高保真仿真
  • 文章类型: Journal Article
    UNASSIGNED: Simulations are used to improve professional practice across multiple health professions; however, the application of simulations in pharmacy curricula has been limited by a lack of evidence.
    UNASSIGNED: To delineate the competencies of pharmacy residents needed to assess their progress while participating in a high-fidelity simulation training program and to create a reliable assessment tool based on these competencies.
    UNASSIGNED: A literature review was conducted, followed by application of a modified Delphi method. An assessment tool based on the results of these activities was drafted (in French). A second modified Delphi process was carried out to assess the reliability of the tool, and the tool was modified accordingly.
    UNASSIGNED: The literature search yielded a total of 2670 articles, of which 289 were included for analysis. The first modified Delphi process involved 19 experts in the first round and 10 experts in the second round. The Cronbach α was 0.866 (95% confidence interval [CI] 0.713-0.960), indicating good reliability. A total of 7 competencies were retained for inclusion in the SIMPHARM assessment tool: professionalism, leadership, teamwork, communication, critical thinking, preparation and packaging of medications, and pharmaceutical calculations. The second modified Delphi process involved 9 experts in the first round and 11 experts in the second round. The final Cronbach α was 0.877 (95% CI 0.741-0.960).
    UNASSIGNED: To the authors\' knowledge, this was one of the largest studies exploring pharmacy competencies in the context of simulations. This work yielded a reliable framework for the assessment of pharmacy residents\' competencies. This assessment tool may help evaluators in assessing the competencies of pharmacy trainees after simulation training.
    UNASSIGNED: Les simulations sont utilisées dans le but d’améliorer la pratique professionnelle de plusieurs professions de la santé; cependant, le manque de données probantes limite leur application dans les programmes d’enseignement en pharmacie.
    UNASSIGNED: Décrire les compétences nécessaires pour évaluer le progrès des résidents en pharmacie qui participent à une formation basée sur un programme de simulation haute-fidélité; et mettre au point un outil d’évaluation fiable qui se base sur ces compétences.
    UNASSIGNED: Une revue de littérature a été effectuée, avant d’appliquer une méthode Delphi modifiée et de faire l’ébauche d’un outil d’évaluation (en français) basé sur les résultats de ces activités. Une deuxième méthode Delphi modifiée a été appliquée pour évaluer la fiabilité de l’outil et celui-ci a fait l’objet de modifications en conséquence.
    UNASSIGNED: La revue de littérature a donné un total de 2670 articles, parmi lesquels 289 ont été inclus à des fins d’analyse. La première méthode Delphi modifiée a impliqué 19 experts pour la première phase, et 10 pour la seconde. Le coefficient alpha de Cronbach était de 0,866 (intervalle de confiance [IC] à 95 % 0,713–0,960), indiquant une bonne fiabilité. Au total, 7 compétences à inclure dans l’outil d’évaluation ont été retenues: professionnalisme, leadership, travail d’équipe, communication, pensée critique, préparation et conditionnement des médicaments, et calculs pharmaceutiques. La deuxième méthode Delphi modifiée impliquait quant à elle 9 experts pour la première phase et 11 pour la seconde. Le coefficient alpha de Cronbach final était de 0,877 (IC à 95 % 0,741–0,960).
    UNASSIGNED: À la connaissance des auteurs, cette étude était l’une des plus importantes se penchant sur les compétences en pharmacie dans le contexte des simulations. Ce travail a donné lieu à un cadre de référence fiable pour évaluer les compétences des résidents en pharmacie. Cet outil d’évaluation pourrait aider les évaluateurs à évaluer les compétences des stagiaires à la suite d’une formation par simulation.

    背景:对于护士来说,临床能力在确保患者接受安全,高质量的护理。多病人模拟(MPS)在护理教育中越来越受到重视,证据表明它适合现实生活。MPS可以成为护士继续临床教育的有效解决方案。
    目的:该项目比较了MPS(包括标准化患者和高保真模拟器)和单个高保真模拟(单个HFS;仅包括高保真模拟器)的有效性,以提高护生的临床能力。
    方法:分层,置换,采用区组随机对照研究设计.
    方法:选择60名3、4、5年级护理本科生参加。组成亚组,每个亚组由三名来自不同年份的护理本科生组成。
    方法:参与者随机接受MPS(干预组)或单一HFS(对照组)1天;他们在30天的清除期后接受相同的干预。使用一份客观测量问卷和两份自我报告问卷来测量临床能力:Creighton能力评估工具(CCEI),临床能力问卷(CCQ),和模拟有效性工具-修改问卷(SET-M)。
    结果:结果显示组间差异显著。具体来说,干预组在CCQ(线性对比[d]=71.4;95%可信区间[CI]=53.407,89.393;P<0.001)和CCEI总分(d=7.17;95%CI=5.837,8.503;P<0.001)方面均表现出比对照组更大的改善.SET-M结果表明,85%的参与者(n=51)强烈同意他们对模拟后将患者移交给医疗团队更有信心。
    结论:研究结果表明,MPS和单一HFS都有效地提高了学生的临床能力。然而,与传统的单一HFS相比,MPS具有更好的教育效果。
    BACKGROUND: For nurses, clinical competency is paramount in ensuring that patients receive safe, high-quality care. Multi-patient simulation (MPS) in nursing education is gaining attention, and evidence shows its suitability for real-life situations. MPS can be an effective solution for nurses\' continuing clinical education.
    OBJECTIVE: This project compares the effectiveness of MPS (involving both a standardized patient and a high fidelity simulator) and a single high-fidelity simulation (single HFS; only involving a high fidelity simulator) for enhancing the clinical competency of nursing students.
    METHODS: A stratified, permuted, block randomized controlled study design was used.
    METHODS: Sixty undergraduate nursing students in years 3, 4, and 5 were selected to participate. Subgroups with each comprising three undergraduate nursing students from different years were formed.
    METHODS: The participants were randomized to receive either an MPS (intervention group) or single HFS (control group) for 1 day; they later received the same intervention after a 30-day washout period. One objectively measured questionnaire and two self-reported questionnaires were used to measure clinical competency: the Creighton Competency Evaluation Instrument (CCEI), Clinical Competence Questionnaire (CCQ), and Simulation Effectiveness Tool - Modified Questionnaire (SET-M).
    RESULTS: The results revealed significant between-group differences. Specifically, the intervention group showed greater improvement than the control group in both the CCQ (linear contrast [d] = 71.4; 95 % confidence interval [CI] = 53.407, 89.393; P < 0.001) and CCEI total scores (d = 7.17; 95 % CI = 5.837, 8.503; P < 0.001). The SET-M results indicated that 85 % of the participants (n = 51) strongly agreed that they felt more confident about performing a patient handover to the healthcare team after the simulation.
    CONCLUSIONS: The study findings indicated that both the MPS and single HFS effectively enhanced students\' clinical competency. However, MPSs have superior educational outcomes relative to traditional single HFSs.

    背景:护理教育已经注意到基于模拟的教育的积极作用。有许多关于模拟教育效果的研究,但是其中大多数涉及一个单一的机构,非随机对照试验,小样本量和对效果的主观评价。这项多中心随机对照试验的目的是评估高保真模拟的效果,基于计算机的模拟,高保真模拟与基于计算机的模拟相结合,并对护理本科生进行个案研究。
    方法:从中国五所大学招募270名护理专业学生。参与者在每个机构被随机分为四组:高保真模拟组,基于计算机的模拟小组,高保真仿真与基于计算机的仿真组相结合,和案例研究小组。最后,239名参与者完成了干预和评估,每组58、67、57和57名参与者。数据收集分为三个阶段:干预前,干预后立即,干预后三个月。
    结果:四组之间的人口统计学数据和基线评估指标没有显着差异。在提高知识的四种方法之间没有观察到统计学上的显着差异,跨专业合作,批判性思维,关怀,或对学习的兴趣。虽然干预后不同组的技能改善有显著差异(p=0.020),三个月后,没有观察到差异(p=0.139)。基于计算机的模拟组的技能提高在干预结束时明显低于高保真模拟组(p=0.048)或高保真模拟结合基于计算机的模拟组(p=0.020)。
    结论:护理专业学生在培养知识方面从四种方法中获益相同,跨专业合作,批判性思维,关怀,和兴趣学习立即和随着时间的推移。高保真仿真和高保真仿真结合基于计算机的仿真在短期内比基于计算机的仿真更有效地提高技能。护理教育工作者可以根据具体情况选择最合适的教学方法来实现预期的学习成果。
    背景:该临床试验已在中国临床试验注册中心注册(临床试验编号:ChiCTR2400084880,注册日期:2024年5月27日)。
    BACKGROUND: Education in nursing has noticed a positive effect of simulation-based education. There are many studies available on the effects of simulation-based education, but most of those involve a single institution, nonrandomized controlled trials, small sample sizes and subjective evaluations of the effects. The purpose of this multicenter randomized controlled trial was to evaluate the effects of high-fidelity simulation, computer-based simulation, high-fidelity simulation combined with computer-based simulation, and case study on undergraduate nursing students.
    METHODS: A total of 270 nursing students were recruited from five universities in China. Participants were randomly divided into four groups at each institution: the high-fidelity simulation group, the computer-based simulation group, the high-fidelity simulation combined with computer-based simulation group, and the case study group. Finally, 239 participants completed the intervention and evaluation, with 58, 67, 57, and 57 participants in each group. The data were collected at three stages: before the intervention, immediately after the intervention, and three months after the intervention.
    RESULTS: The demographic data and baseline evaluation indices did not significantly differ among the four groups. A statistically significant difference was not observed between the four methods for improving knowledge, interprofessional collaboration, critical thinking, caring, or interest in learning. While skill improvement differed significantly among the different groups after the intervention (p = 0.020), after three months, no difference was observed (p = 0.139). The improvement in skill in the computer-based simulation group was significantly lower at the end of the intervention than that in the high-fidelity simulation group (p = 0.048) or the high-fidelity simulation combined with computer-based simulation group (p = 0.020).
    CONCLUSIONS: Nursing students benefit equally from four methods in cultivating their knowledge, interprofessional collaboration, critical thinking, caring, and interest in learning both immediately and over time. High-fidelity simulation and high-fidelity simulation combined with computer-based simulation improve skill more effectively than computer-based simulation in the short term. Nursing educators can select the most suitable teaching method to achieve the intended learning outcomes depending on the specific circumstances.
    BACKGROUND: This clinical trial was registered at the Chinese Clinical Trial Registry (clinical trial number: ChiCTR2400084880, date of the registration: 27/05/2024).

    结论:结果提供了有力的证据,支持将高保真模拟整合到本科护理课程中以提高学生的知识和表现。报告的高度异质性可能归因于研究背景或方法的变化。未来的研究应该探索高保真模拟在不同教育和文化背景下的最佳使用。
    OBJECTIVE: This umbrella review aimed to consolidate the evidence base on the impact of high-fidelity simulation on knowledge and performance among undergraduate nursing students.
    METHODS: Umbrella review with meta-analyses of pooled effect sizes, followed by an additional meta-analysis of primary studies from the included systematic reviews, excluding overlapping results.
    METHODS: Systematic searches were performed up to August 2023 in PubMed, Embase, and Cochrane Library. We included reviews that compared high-fidelity simulation against other learning strategies.
    METHODS: The risk of bias was assessed for each included systematic review (ROBIS tool) and primary study (RoB 2 or ROBINS-I as appropriate). Random-effect meta-analyses of meta-analyses were performed to estimate the pooled effects of high-fidelity simulation on knowledge and performance. Further random-effect meta-analyses of primary studies were conducted, with overlapping studies excluded (12 %). Subgroup analyses were performed to provide a more comprehensive analysis of the findings. Trim-and-fill analyses were conducted to adjust for potential publication bias.
    RESULTS: Six systematic reviews were included and encompassed 133 primary studies (2767 and 3231 participants concerning performance and knowledge, respectively). The adjusted pooled effects for knowledge (SMD = 0.877, 95 % CI: 0.182 to 1.572) and performance (SMD = 0.738, 95 % CI: 0.466 to 1.010) closely aligned with those obtained from meta-analyzing the primary studies for knowledge (SMD = 0.980) and performance (SMD = 0.540), both showing high statistical heterogeneity. Traditional lectures represented the more common comparison. The subgroup analysis revealed significant differences in effect sizes across geographic locations, topics, types of control, and how interventions were reported.
    CONCLUSIONS: The results provide robust evidence supporting the integration of high-fidelity simulation into undergraduate nursing programs to enhance students\' knowledge and performance. The high reported heterogeneity may be attributed to variations in study contexts or methodologies. Future research should explore the optimal use of high-fidelity simulation in different educational and cultural contexts.

    目标:跨专业教育因其协作和团队合作的潜力而被认可,反映临床实践;然而,基于模拟的跨专业教育的现有文献不包括医师助理(PA)学生。该计划旨在探索学生对PA学生和专职健康专业(AHP)学生的跨专业临床模拟的看法,作为我们计划开发的一部分。
    方法:为来自PA的志愿学生设计并进行了高保真模拟课程,护理人员科学,和物理治疗课程。我们使用了混合方法的电子问卷,该问卷由15个按数字评分量表(0-5)进行评分的陈述和四个开放式问题以及无限的自由文本回答组成,以探索学生的看法。定性分析采用归纳主题分析。会议设计以Allport的(组间)联系假设为基础,强调相互的组间差异。
    结果:46名学生参加了模拟教学,48%(n=22)提供反馈。学生的总体看法对跨专业模拟主要是积极的;然而,认识到一些学习障碍。基于对我们倡议的评估和现有文献,我们提出了5个顶级技巧,以促进学生的有效学习体验。(1)了解跨专业协作的重要性。(2)明确角色。(3)提前规划场景。(4)保持群体之间的平等地位。(5)提供明确的指示和期望。
    结论:据我们所知,这是涉及PA和AHP学生的高保真跨专业模拟的第一项研究。我们成功地探索了学生的感知,这些感知突出了可能影响学习的方面。这项试点研究表明,跨专业模拟对我们的学生来说是一种可行且可接受的学习形式,并强调了如何改善未来的跨专业模拟教学课程。
    OBJECTIVE: Interprofessional education is recognized for its potential for collaboration and teamwork, reflecting clinical practice; however, existing literature for simulation-based interprofessional education does not include Physician Associate (PA) students. This initiative aimed to explore the students\' perception of interprofessional clinical simulation for PA students and allied health professional (AHP) students as part of our program development.
    METHODS: A high-fidelity simulation session was designed and conducted for volunteering students from the PA, paramedic science, and physiotherapy courses. We used a mixed-method electronic questionnaire consisting of 15 statements rated on a numerical rating scale (0-5) and four open-ended questions with unlimited free-text responses to explore student perceptions. Inductive thematic analysis was used for qualitative analysis. The session design was underpinned by Allport\'s (intergroup) contact hypothesis with an emphasis on mutual intergroup differentiation.
    RESULTS: Forty-six students participated in the simulation teaching, with 48% (n = 22) providing feedback. Overall student perception was mainly positive toward the interprofessional simulation; however, some barriers to learning were recognized. Based on the evaluation of our initiative and existing literature, we propose 5 top tips to promote an effective learning experience for students. (1) Understand the importance of interprofessional collaboration. (2) Establish clear roles. (3) Plan the scenarios in advance. (4) Maintain equal status between groups. (5) Provide clear instructions and expectations.
    CONCLUSIONS: To our knowledge, this is the first study of high-fidelity interprofessional simulation involving PA and AHP students. We successfully explored student perception which highlighted aspects that can impact learning. This pilot study demonstrated that interprofessional simulation is a feasible and acceptable form of learning for our students and highlighted how to improve future interprofessional simulation teaching sessions.

    目的:对在护生教学中使用高保真模拟的有效性进行综述,从而支持教学从业人员实施高保真模拟干预策略的持续改进。
    背景:近年来,一些系统综述已经研究了高保真模拟在护生教学中的有效性。然而,结论各不相同,缺乏系统的评估。
    方法:本综述包括一个总括性综述。
    方法:搜索PubMed,Embase,科克伦图书馆,进行了WebofScience和OVID数据库,以检索从数据库开始到2023年11月的护理学生教学中高保真模拟有效性的总括审查数据。纳入的系统评价的质量由两名评审员使用AMSTAR2和PRISMA量表独立评估。所包括的系统评价的结果指标使用GRADE系统进行分级。
    结果:纳入了12篇系统综述,重点关注护理学生教学中高保真模拟的有效性。值得注意的是,所有12项系统评价都表现出很低的方法论质量,有9人表现出一定程度的报告缺陷,2个表现出严重的信息缺陷,1个报告相对完整的信息。共纳入22项结果指标和53份证据。结果发现15份低质量证据和38份极低质量证据。越来越多的证据表明,高保真模拟教学有效地提高了护生的理论表现,实践技能和各种临床综合能力,突出积极的教学效果。然而,通过高质量的进一步验证,大样本研究是必要的。
    结论:目前评估高保真模拟在护生教学中的有效性的系统评价的总体证据质量较低。此外,方法质量和报告标准化程度需要进一步提高。因此,高品质,大样本随机对照试验对于进一步证实高保真模拟在护生教学中的有效性至关重要.
    OBJECTIVE: To conduct an umbrella review of the effectiveness of using high-fidelity simulation in nursing student teaching, thereby supporting continuous improvement in teaching practitioners\' implementation of high-fidelity simulation intervention strategies.
    BACKGROUND: Several systematic reviews have investigated the effectiveness of high-fidelity simulation in nursing student teaching in recent years. However, conclusions vary and a systematic assessment is lacking.
    METHODS: This review encompasses an umbrella review.
    METHODS: A search of PubMed, Embase, Cochrane Library, Web of Science and OVID databases was conducted to retrieve data on an umbrella review of high-fidelity simulation effectiveness in nursing student teaching from database inception to November 2023. The quality of the included systematic reviews was independently assessed by two reviewers using the AMSTAR 2 and PRISMA scales. Outcome indicators from the included systematic reviews were graded using the GRADE system.
    RESULTS: Twelve systematic reviews focusing on high-fidelity simulation effectiveness in nursing student teaching were included. Notably, all 12 systematic reviews exhibited very-low methodological quality, with 9 exhibiting some degree of reporting deficiencies, 2 exhibiting severe information deficiencies and 1 reporting relatively complete information. A total of 22 outcome indicators and 53 pieces of evidence were included. The results revealed 15 pieces of low-quality evidence and 38 pieces of very-low-quality evidence. Mounting evidence suggests that high-fidelity simulation teaching effectively enhances nursing students\' theoretical performance, practical skills and various clinical comprehensive abilities, highlighting a positive teaching effect. However, further validation through high-quality, large-sample studies is warranted.
    CONCLUSIONS: The overall evidence quality of the current systematic reviews evaluating high-fidelity simulation effectiveness in nursing student teaching is low. Additionally, the methodological quality and the degree of reporting standardization require further improvement. Therefore, high-quality, large-sample randomized controlled trials are essential for further substantiating high-fidelity simulation effectiveness in nursing student teaching.

    这项研究的重点是模拟由石蜡堆叠球作为透视聚合物相变材料组成的异质介质中的传热。主要目标是研究数值方案的要求,以正确预测由受到温度梯度的球形颗粒的无限重复配置组成的周期性系统中的热导率。基于OpenFOAM,创建了一个模拟平台,通过该平台系统地推断了精确传热预测的分辨率要求。该方法针对包含单个球体或两个球体的配置的单位单元进行了说明。在网格足够精细以具有覆盖球体直径距离的八个或更多个网格单元的情况下,可以建立证实该方法二阶精度的渐近收敛率。可以创建具有两个球体的配置,其中在这些球体之间保留小间隙。发现即使这些小间隙的分辨率不足,也不会为域中的温度场产生不准确的数值解,只要每个球体直径坚持使用八个或更多的网格单元。可以以高保真度和实际计算成本来模拟配置中的重叠和(几乎)接触球体。这项研究进一步扩展到检查晶胞的有效热导率,在单位细胞包含单个球体的情况下,特别关注石蜡的体积分数。最后,我们探索了包含两个球体之间不同距离的晶胞的有效热导率的依赖性。
    This research focuses on modeling heat transfer in heterogeneous media composed of stacked spheres of paraffin as a perspective polymeric phase-change material. The main goal is to study the requirements of the numerical scheme to correctly predict the thermal conductivity in a periodic system composed of an indefinitely repeated configuration of spherical particles subjected to a temperature gradient. Based on OpenFOAM, a simulation platform is created with which the resolution requirements for accurate heat transfer predictions were inferred systematically. The approach is illustrated for unit cells containing either a single sphere or a configuration of two spheres. Asymptotic convergence rates confirming the second-order accuracy of the method are established in case the grid is fine enough to have eight or more grid cells covering the distance of the diameter of a sphere. Configurations with two spheres can be created in which small gaps remain between these spheres. It was found that even the under-resolution of these small gaps does not yield inaccurate numerical solutions for the temperature field in the domain, as long as one adheres to using eight or more grid cells per sphere diameter. Overlapping and (barely) touching spheres in a configuration can be simulated with high fidelity and realistic computing costs. This study further extends to examine the effective thermal conductivity of the unit cell, particularly focusing on the volume fraction of paraffin in cases with unit cells containing a single sphere. Finally, we explore the dependence of the effective thermal conductivity for unit cells containing two spheres at different distances between them.

    目的:评估与基于病例的讨论相比,高保真模拟儿科紧急情况对自信心发展的影响,理论知识,临床推理,通信,态度,和领导本科医学生。
    方法:33名医学生被分配到两种教学方法中:高保真模拟(HFS,n=18)或基于案例的讨论(CBD,n=15)。在干预前后应用自信心和知识测试,并使用混合效应模型估计HFS对两种结果的影响。在干预措施之后,进行了客观的结构化临床检查活动,虽然两个独立的评估者使用特定的模拟检查表来评估临床推理,通信,态度,和领导力。用线性和逻辑回归估计HFS对这些结果的影响。结果:两组的自信心(HFS59.1×93.6,p<0.001;CDB50.5×88.2,p<0.001)和知识得分(HFS45.1×63.2,p=0.001;CDB43.5×56.7,p值<0.01)均增加。但两组测试(分别为p=0.6565和p=0.3331)之间没有观察到差异(根据学生排名调整的混合效应模型中的组*时间效应).HFS组的模拟检查表得分高于CBD组,在所有域中具有较大的效果大小(对冲g1.15至2.20)。
    结论:HFS在开发临床推理方面比CBD表现更好,通信,态度,以及在儿科急诊护理本科医学生中的领导力,但在自信心和理论知识方面没有观察到显著差异。
    OBJECTIVE: To evaluate the effect of high-fidelity simulation of pediatric emergencies compared to case-based discussion on the development of self-confidence, theoretical knowledge, clinical reasoning, communication, attitude, and leadership in undergraduate medical students.
    METHODS: 33 medical students were allocated to two teaching methods: high-fidelity simulation (HFS, n = 18) or case-based discussion (CBD, n = 15). Self-confidence and knowledge tests were applied before and after the interventions and the effect of HFS on both outcomes was estimated with mixed-effect models. An Objective Structured Clinical Examination activity was conducted after the interventions, while two independent raters used specific simulation checklists to assess clinical reasoning, communication, attitude, and leadership. The effect of HFS on these outcomes was estimated with linear and logistic regressions. The effect size was estimated with the Hedge\'s g.
    RESULTS: Both groups had an increase in self-confidence (HFS 59.1 × 93.6, p < 0.001; CDB 50.5 × 88.2, p < 0.001) and knowledge scores over time (HFS 45.1 × 63.2, p = 0.001; CDB 43.5 × 56.7, p-value < 0.01), but no difference was observed between groups (group*time effect in the mixed effect models adjusted for the student ranking) for both tests (p = 0.6565 and p = 0.3331, respectively). The simulation checklist scores of the HFS group were higher than those of the CBD group, with large effect sizes in all domains (Hedges g 1.15 to 2.20).
    CONCLUSIONS: HFS performed better than CBD in developing clinical reasoning, communication, attitude, and leadership in undergraduate medical students in pediatric emergency care, but no significant difference was observed in self-confidence and theoretical knowledge.

    This article was migrated. The article was marked as recommended. Background: Final year medical students at the University Duisburg-Essen, Germany, are unsatisfied with their clinical judgement skills in common elective and emergency clinical situations. A competency based medical curriculum determines that clinical judgement is an essential tool in effective patient care, patient safety and limiting clinical error. Approaches to clinical judgement include either analytical, intuitive or a combination of both approaches. Novices show specific factors, which are typical in inexperienced clinicians. Simulation provides opportunities in a competency-based medical education curriculum. There is limited evidence showing that simulation can provide an effective environment for teaching and learning clinical decision-making skills. This project explores how final year medical students at the University of Duisburg-Essen approach the clinical decision-making process as well as how simulation influences this process. Methods: Ethics approval was obtained from the local ethics committee. After completing a 10-week simulation course,thirty-five students completed a clinical decision-making instrument to categorise their clinical decision-making approaches. The Novice Decision Making Model and the Cognitive Continuum Model were combined with learning theories in Simulation (Social Cognitive Theory) and used to explore and interpret data collected through questionnaires, interviews and observation. Results: The majority (60%) of students employed a predominantly analytic approach, some students showed intuitive tendencies in clinical situations. During interviews students displayed typical novice approaches to decision-making and expressed positive comments relating to simulation. Conclusions: Simulation presents an opportunity for teaching and learning clinical decision-making. Results show the need for further inquiry into learning clinical decision-making through simulation. This research provides initial evidence that simulation can be incorporated into curricular teaching of clinical decision-making.

  • 文章类型: Systematic Review
    背景:关于如何处理大规模伤亡事件(MCI)的急救人员培训和学习传统上是基于阅读和/或通过基于计算机的场景进行培训,或者有时通过与演员的现场模拟。急救人员应在现实环境中实践,以缩小理论与实践的差距,重复训练的可能性对学习很重要。高保真虚拟现实(VR)是一种用于现实和可重复的模拟训练的有前途的工具,但需要进一步评估。这篇文献综述的目的是提供对急救人员使用高保真VR进行MCI训练的全面描述。
    方法:根据Whittemore和Knafl的描述,采用系统综合文献综述。调查的数据库是PubMed,CINAHL完成,学术搜索终极,WebofScience,和ERIC找到解决目标结果的论文。电子搜索策略确定了797项潜在研究。17项研究被认为有资格最终纳入。
    结果:使用VR进行训练可以以实时模拟无法实现的方式进行重复,现实主义是相似的,但没有那么紧张。虚拟现实提供了一个经济高效且安全的学习环境。VR的可用性取决于沉浸水平,该技术没有错误,和易用性。
    结论:这项综合审查表明,高保真VR训练不应排除实时模拟,而是作为一种补充。在接受高保真VR培训后,急救人员变得更加自信,并为现实生活中的MCI做好了准备,但是应该努力解决这次审查中发现的技术问题,以进一步提高可用性。
    BACKGROUND: First responders\' training and learning regarding how to handle a mass-casualty incident (MCI) is traditionally based on reading and/or training through computer-based scenarios, or sometimes through live simulations with actors. First responders should practice in realistic environments to narrow the theory-practice gap, and the possibility of repeating the training is important for learning. High-fidelity virtual reality (VR) is a promising tool to use for realistic and repeatable simulation training, but it needs to be further evaluated. The aim of this literature review was to provide a comprehensive description of the use of high-fidelity VR for MCI training by first responders.
    METHODS: A systematic integrative literature review was used according to Whittemore and Knafl\'s descriptions. Databases investigated were PubMed, CINAHL Complete, Academic Search Ultimate, Web of Science, and ERIC to find papers addressing the targeted outcome. The electronic search strategy identified 797 potential studies. Seventeen studies were deemed eligible for final inclusion.
    RESULTS: Training with VR enables repetition in a way not possible with live simulation, and the realism is similar, yet not as stressful. Virtual reality offers a cost-effective and safe learning environment. The usability of VR depends on the level of immersion, the technology being error-free, and the ease of use.
    CONCLUSIONS: This integrative review shows that high-fidelity VR training should not rule out live simulation, but rather serve as a complement. First responders became more confident and prepared for real-life MCIs after training with high-fidelity VR, but efforts should be made to solve the technical issues found in this review to further improve the usability.
