The scope of computerized simulation in competency-based maxillofacial training: a systematic review
《International journal of oral and maxillofacial surgery》2022,51(8):1101-1110
Oral and maxillofacial surgery (OMS) teaching is set to undergo a paradigm shift towards competency-based training. With increasing focus on resident skill development and patient safety, computerized simulators are likely to play a more mainstream role in OMS training. A systematic review of the available literature was conducted, in accordance with the PRISMA guidelines, to highlight the scope of computerized simulation in OMS teaching. A PubMed search was performed by two independent reviewers, and 35 articles published in English between 2010 and 2021 that reported the use of computerized simulation for teaching maxillofacial procedures were included in the analysis. Eight articles on minor oral surgery, seven on orthognathic surgery, five on maxillofacial trauma, five on cleft lip and palate surgery, three articles each on nerve block techniques, endoscopic procedures, and reconstructive surgery, and one article on fibre-optic intubation reported the use of computerized simulation that can be applied to OMS training. Ten randomized controlled trials were identified in the search. However there was marked heterogeneity among the studies. Simulator training for skill acquisition mentored by an expert OMS educator could offer holistic resident training; however more studies that test common themes of resident training such as knowledge acquisition and skill development are necessary. 相似文献

An essential role of critical care advanced practice providers—advanced practice registered nurses and physician assistants—is to have knowledge and competency to make accurate and efficient decisions. The ability to manage clinical scenarios involving medically deteriorating patients requires higher-order cognitive thinking and leadership skills that are challenging to extrapolate in traditional interviews. In critical care, advanced practice providers must make rapid clinical assessments and implement appropriate medical interventions to deter progression of life-threatening illnesses. Adding clinical simulation to the traditional interview allows interviewers to evaluate applicants’ crisis resource management skills, leadership, and clinical competency. 相似文献

AimThis study aimed to develop and identify the effects of a tiered competence-based simulation educator development program on knowledge, competence and attitudes.BackgroundCompetence and educational needs-based training is required to improve nursing simulation educators' learning outcomes.DesignThis study used a one-group pretest–posttest design.MethodsA convenience sample of 65 nursing simulation educators completed a self-administered questionnaire. Three levels of training programs were implemented: basic, intermediate and advanced courses. The pretest–posttest differences in knowledge, competence and attitude scores were analyzed using the paired t-test. The main variable scores for the three programs were compared using one-way ANOVA and the Scheffé post hoc test.ResultsPosttest levels of knowledge, competence and attitudes were higher than the pretest measures. Simulation educators in the basic course reported greater improvements in perceived competence when compared with participants in the intermediate course.ConclusionsThe tiered competence-based simulation educator development program improved nursing simulation educators' knowledge, competence and attitudes across all course levels. 相似文献

The aim of this study is to provide an improved method for traffic accident reconstruction based on geomatics techniques and numerical simulations. A combination of various techniques was used. First, an unmanned aerial vehicle (UAV), laser scanner and structured-light scanner were used to obtain information on the accident scene, vehicle and victim. The collected traces provided detailed initial impact conditions for subsequent numerical simulations. Then, multi-body system (MBS) simulations were conducted to reconstruct the kinematics of the car-to-pedestrian collision. Finally, a finite element (FE) simulation using the THUMS model was performed to predict injuries. A real-life vehicle-pedestrian collision was used to verify the feasibility and effectiveness of this method. The reconstruction result revealed that the kinematic and injury predictions of the numerical simulations effectively conformed to the surveillance video and investigation of the actual accident. UAV photogrammetry was demonstrated to be more efficient in accident data collection than hand sketch and measurement, and 3D laser scanning enabled an easier and more accurate modeling process of vehicle. The present study shows the feasibility of this method for use in traffic accident reconstruction. 相似文献

目的:探讨实时呼吸监测(RPM)技术在盆腔肿瘤放射治疗CT模拟定位中的应用价值。方法:选取我院2019年5月-2019年12月盆腔肿瘤放疗患者70例,其中实验组和对照组各35例。实验组患者CT模拟定位时采用RPM监测患者呼吸状态稳定后定位扫描,对照组常规方法定位扫描,利用锥形束CT采集患者放疗时的摆位误差信息同时记录当次放疗是否重复摆位,应用统计学方法对两组患者放疗时的摆位误差及重复摆位率数据进行分析。结果:两组在Y、Z 轴线性方向、X轴旋转方向误差及重复摆位率比较有统计学差异(P<0.05),X轴线性方向及Y、Z轴旋转方向误差比较无统计学意义(P>0.05)。结论:盆腔肿瘤放疗患者在行CT模拟定位时应实时关注其身体状态变化,采用实时呼吸监测可有效的观测患者是否有紧张情绪或其他身体不适,避免了CT模拟定位时患者异常身体状态引起的放疗误差,可显著提高放射治疗精度及效率。 相似文献
