Improving the Stunting Early Detection Competence of Nursing Students Through Clinical Simulation Video In Nursing Project (ALLADIN)

Stunting is a major problem that occurs in Indonesia. Early detection needs to be done to prevent stunting. Nursing students have the competence to perform early detection. The Alladin project is a solution to improve the competence of nursing students to prevent stunting. The purpose of this study was to determine the competency improvement of nursing students in early detection of stunting through Alladin (Clinical Simulation Video In Nursing Project). This study used a pre-experimental pre-test and post-test design without a control group. The sample in this study amounted to 42 respondents who were divided into 21 intervention groups and 21 control groups based on total sampling. This research was conducted for six months at the Singkawang Department of Nursing. The questionnaires used in this research are knowledge, learning motivation, and standard operating procedures (SOP) questionnaires. The results showed a significant increase in knowledge with a value of sig = 0.001 and there was no difference in motivation before and after the intervention, the value of sig = 0.358. Recommendations from this research as a learning medium for pediatric nursing in academic and clinical settings of pediatric nursing in hospitals and primary care facilities.

Aggregation of Hierarchically-Organized Agents in a Multi-Agent System

Artificially intelligent agents are enjoying increased adoption in both the video game and simulation industry - being used for both training and education as well as entertainment purposes with largescale real-time strategy games. Both type of systems have a need for the simulation of large numbers of units. While traditional scalability solutions (e.g. segmenting the terrain and using separate hardware to process various sections) can be used, this is wasteful of processing power which could have been better used to approximate the results of far-flung conflict while disaggregating close-in conflict for the benefit of the user/trainee. Approaches to do so haven’t been investigated due to the smaller scales of simulations until recent developments. This paper provides an introduction to a modeling approach that can be used to bridge optimal control techniques with wargaming AI agents in order to provide cohesive aggregated and disaggregated AI forces within simulations.

Hierarchical, Discontinuous Agent Reinforcement Learning Rewards in Complex Military-Oriented Environments

Artificially intelligent agents are seeing increased adoption in both the video game and simulation industry for training, education, and entertainment purposes. These systems often need realistic and believable opponents that must achieve objectives in the face of competing and contradictory priorities and frequently require the rapid creation of a wide spectrum of agents with disparate behaviors that reflect tactical realism. This in turn drives the need for the dynamic training of such agents from available source data. Approaches to do so have yet to be widely investigated due to the smaller scales of these simulation environments. This paper discusses techniques to quickly design and generate a variety of AI agents that follow desired tactics and procedures, including realistic situations that require trade-off decisions between competing objectives. Techniques described include an investigation into deep reinforcement agents that have separable reward structures and can prioritize and re-prioritize goals based on a hierarchy.

The impact of an educational program on nurses' shared decision making attitudes: A randomized controlled trial

AimsAlthough medical professionals possess a positive attitude toward SDM, they lack of a complete understanding of conceptual shared decision making (SDM). Therefore, a related knowledge base must be constructed to enhance service education. We aimed to examine the effectiveness of an educational program with situational simulation video on nurses' SDM attitude. MethodsA randomized controlled trial with single-blind study design was conducted, and permuted block randomization was employed. Participants were randomly assigned to an experimental group (n = 50) or control group (n = 50). Only the experimental group received education programs within 2 weeks, with the first covering the basic concept of SDM and the second comprising situation simulation teaching. In both groups, data were collected prior to intervention as baseline, immediately after intervention to evaluate its immediate effects, and 2 months after intervention to test the delay effect. A generalized estimating equation, subgroup analysis and descriptive statistics were used to analyse data. ResultsA significant main effect over time was discovered. Nevertheless, no significant group-time interaction was noted between the two groups after a 2-month interval. Subgroup analysis reveals that the SDM attitude scores in both the experimental and control groups increase for within group. The improvement of SDM attitude score in the experiment group was better than control group at follow test. ConcisionsThe findings of this study might provide a reference for health care providers when designing service education courses to improve the execution strategies of SDM and thus the quality of care provided.

Can Simulation be a Learning and Assessment Tool for Collaborative Learning in the Preclinical Years?

Collaborative learning cases (CLC) is a new model of teaching and learning in healthcare education based on patient problems. Basic medical sciences and clinical sciences are integrated in case‐based scenarios simulating with real‐life situations1. The most common problem in the medical curriculum is that medical students have poor understanding of clinical conditions due to the inability to apply basic concepts to clinical practice. This is largely due to some curricula having a didactic teaching pedagogy with a teacher‐centric and discipline‐specific format along with content overload. The imperative was to develop teaching‐learning formats based on collaborative learning, breaking away from the traditional didactic large group lecture sessions. This would promote self‐directed, student‐centred learning, which would lead to deeper learning, the acquisition of meaningful content and consequently, ideal educational outcomes2. Furthermore, these learning methods would promote and develop domain‐independent skills such as collaboration, respect, leadership, communication and research skills, professionalism/ ethical behaviours, and lifelong learning skills.CLCs also serve as the capstone to align the lectures, tutorials, simulations, and practical sessions. Prior to a CLC session, students take the pre‐reading and pre‐quiz (Fig. 1), and the in‐class activities are facilitated by trained tutors (Fig. 2). During the CLC, a simulated patient (SP) and videos are shared in a sequential manner to facilitate discussion and strengthen student clinical reasoning skills. Evaluation of the CLCs are conducted through surveys involving students, tutors and SPs who observe the interaction between them and the students. These feedbacks are valuable and are frequently used as formative and summative assessment.Thus, CLCs can help students to better understand the relevance of basic medical sciences by integrating it with clinical sciences, encourage deeper learning, promote collaboration and lifelong learning. In this symposium, we will discuss the rationale and process of developing CLCs as well as the strengths and limitations. Further, we will explore these ideas in more details and engage in a collegial discussion that will broaden our perspective on collaborative learning.ReferencesThistlethwaite JE, Davies D, Ekeocha S, Kidd JM, MacDougall C, Matthews P, Clay D.

(Safe) Sex on My Mind: The Effects of a Safe Sex Prime and an Alcohol Prime on Sex-Related Perceptions and Behavior

Previous research suggests that exposure to alcohol primes (i.e., stimuli associated with alcohol) affects drinkers' perceptions and behaviors. The present study investigated the effects of an environmental alcohol prime (being in a simulated bar setting) and a safe sex message prime (a public health safe sex message) on sexually active alcohol drinkers. Participants (n = 80) were assigned to one of four conditions according to priming allocation and engaged in a simulated video chat with a potential partner. They reported their sex-related self-perceptions and perceptions of a potential partner upon procedural completion. The alcohol-related environmental prime led participants to rate their potential partner as being significantly less inhibited and more sexual. The safe sex message significantly reduced reported sex-related self-perceptions and perceptions of their partners' disinhibition. There was a significant effect of primes on participants' perceptions of their partner's friendliness--participants exposed to either or both prime(s) perceived their partner as being friendlier than participants exposed to no prime. Results suggest that environmental alcohol primes may strengthen sexually active drinkers' perceptions of a potential partner's disinhibition and sexuality even before alcohol consumption begins, and that a safe sex message may moderate these effects. The presence of safe sex messages in alcohol-related environments may positively influence sexual risk decision making among sexually active drinkers.

Deep learning methodology for predicting time history of head angular kinematics from simulated crash videos

Head kinematics information is important as it is used to measure brain injury risk. Currently, head kinematics are measured using wearable devices or instrumentation mounted on the head. This paper evaluates the deep learning approach in predicting time history of head angular kinematics directly from videos without any instrumentation. To prove the concept, a deep learning model was developed for predicting time history of head angular velocities using finite element (FE) based crash simulation videos. This FE dataset was split into training, validation, and test datasets. A combined convolutional neural network and recurrent neural network based deep learning model was developed using the training and validations sets. The test (unseen) dataset was used to evaluate the predictive capability of the deep learning model. On the test dataset, correlation coefficient obtained between the actual and predicted peak angular velocities was 0.73, 0.85, and 0.92 for X, Y, and Z components respectively.

Adaptive singular value shrinkage estimate for low rank tensor denoising

Recently, tensors are widely used to represent higher-order data with internal spatial or temporal relations, e.g. images, videos, hyperspectral images (HSIs). While the true signals are usually corrupted by noises, it is of interest to study tensor recovery problems. To this end, many models have been established based on tensor decompositions. Traditional tensor decomposition models, such as the CP and Tucker factorization, treat every mode of tensors equally. However, in many real applications, some modes of the data act differently from the other modes, e.g. channel mode of images, time mode of videos, band mode of HSIs. The recently proposed model called t-SVD aims to tackle such problems. In this paper, we focus on tensor denoising problems. Specifically, in order to obtain low-rank estimators of true signals, we propose to use different shrinkage functions to shrink the tensor singular values based on the t-SVD. We derive Stein’s unbiased risk estimate (SURE) of the proposed model and develop adaptive SURE-based tuning parameter selection procedure, which is totally data-driven and simultaneous with the estimation process. The whole modeling procedure requires only one round of t-SVD. To demonstrate our model, we conduct experiments on simulation data, images, videos and HSIs. The results show that the proposed SURE approximates the true risk function accurately. Moreover, the proposed model selection procedure picks good tuning parameters out. We show the superiority of our model by comparing with state-of-the-art denoising models. The experiments manifest that our model outperforms in both quantitative metrics (e.g. RSE, PSNR) and visualizing results.

Evaluating Simulation-Based Tobacco Treatment Scenarios for Providers Delivering Treatment for People Living With Mental Illnesses.

BackgroundPeople living with mental illnesses (PMI) experience elevated tobacco use and related morbidity and mortality. Despite the availability of effective and safe tobacco treatments along with evidence that PMI are motivated and able to quit successfully, few Mental and behavioral healthcare providers (MHPs) engage PMI in such treatment. MHPs may lack the confidence or skills to engage their clients in tobacco treatment. Currently, there are limited training modalities to prepare MHPs in delivering tobacco treatment for PMI. However, animated scenario-based simulated encounters can bridge this gap to effectively provide tailored MHP training to enhance treatment delivery. Hence, the purpose of this study was to evaluate simulated tobacco treatment education scenarios tailored to MHPs.MethodsFor this evaluation, we used a pretest-posttest design to assess changes in MHPs tobacco treatment knowledge and behavioral intentions after viewing simulated treatment encounters. We developed four animated scenarios, using brief tobacco treatment interventions, simulating treatment encounters with PMI. MHPs were primarily recruited from mental or behavioral healthcare facilities and were asked to complete a web-based questionnaire. Their knowledge, views, and experiences in providing tobacco treatment were assessed prior to viewing the animated scenarios. Participants were then asked to evaluate the desirability, acceptability, and applicability of the animated scenarios; and thereafter, their knowledge of and intentions to provide evidence-based tobacco treatment (i.e., ASK, ADVISE, ASSESS, ASSIST, ARRANGE) were again assessed.ResultsParticipants (N = 81) were on average 41.0 years of age, mostly female (79.0%), and non-Hispanic White (86.4%). Nearly a quarter endorsed current tobacco use and few had tobacco treatment training (14.8%). Overall knowledge of tobacco treatment scores significantly increased before and after viewing the videos (M = 3.5 [SD = 1.0] to M = 4.1 [SD = 1.0], p < 0.0001). After viewing the simulated scenario videos, participants endorsed moderate to high mean scores (ranging from 4.0-4.2 on a 0 to 5 scale) on the desirability, acceptability, and applicability of the different animated scenarios. In addition, after viewing the scenarios the proportion of participants who endorsed that they intended to occasionally/very often engage clients in evidence based tobacco treatment were high for ASK (94.9%), followed by ADVISE and ASSESS (84.7% each), followed by ASSIST (81.4%), and ARRANGE (74.6%). Evaluation scores significantly differed by type of animated scenario and participants' work settings and discipline.ConclusionsThese findings suggest that the use of brief animated scenarios may be a useful modality to enhance MHPs knowledge acquisition and treatment delivery intentions. Such approaches may be integrated into tobacco treatment trainings for MHPs.

Realizing Inclusion and Systemic Equity in Medicine: Upstanding in the Medical Workplace (RISE UP)-an Antibias Curriculum.

IntroductionRacism is a public health threat, and racist behaviors adversely affect clinicians in addition to patients. Medical trainees commonly experience racism and bias. More than half of pediatric residents at a single institution reported experiencing or witnessing discriminatory behavior at work; only 50% reported receiving training on implicit bias, delivering difficult feedback, or peer support. Our multispecialty team created Realizing Inclusion and Systemic Equity in Medicine: Upstanding in the Medical Workplace (RISE UP), an antibias, anti-racism communication curriculum composed of three hybrid (virtual and in-person) workshops.MethodsDuring the pediatric resident workshops, we introduced tools for addressing bias, presented video simulations, and led small-group debriefings with guided role-play. We also reviewed escalation pathways, reporting methods, and support systems. Residents completed an evaluation before and after each workshop to assess the curriculum's efficacy.ResultsThirty-nine residents participated in RISE UP, with 20 attending all three workshops. Ninety-six percent of participants indicated they would recommend the workshops to colleagues. After the third workshop, 92% reported having tools to respond to bias, and 85% reported knowing how to escalate concerns regarding discriminatory behavior. Chief residents were most frequently identified as sources of resident support when encountering discriminatory behavior.DiscussionThis curriculum was successful in developing and strengthening residents’ responses to discrimination, including upstander support. The curriculum is adaptable for virtual, in-person, and hybrid settings, allowing for flexibility. Establishing institutional support, promoting faculty development, and creating and disseminating escalation pathways are critical to addressing racism in health care.

The Effectiveness of Simulation in Education 4.0: Application in a Transesophageal Echocardiography Training Program in Malaysia.

IntroductionA Malaysian Higher Education Provider has applied technology as part of its pedagogical approach, in alignment with Education 4. 0. The use of simulation, which aligns with the principles of Education 4.0, employs digital technologies and supports learning by bridging the classroom and the clinical areas. We reported the effectiveness of learning in our program that utilizes multimodal pedagogy, including interactive lectures, pre-recorded video lectures, simulation, and hands-on supervised clinical sessions, using the program's cumulative assessment data.MethodologyThis program evaluation was based on Kirkpatrick's framework. End-points for learning (Kirkpatrick level 2) were analyzed based on improved overall post-test theoretical and clinical assessment performance. Quantitative data analysis of theoretical pre-test, theoretical post-test, clinical assessment, and post-test scores was performed to compare cohorts.ResultsThe performance of 19 trainees, over six cohorts from 2012 to 2019, were analyzed. All our trainees had equal opportunities to learn using the multimodal pedagogy, including a simulator. The analysis of pre- and post-theoretical test scores showed a significant improvement in the mean scores (pre-test 48.7% (± SD 9), post-test 64.1% (± SD11.5); p ≤ 0.001). Overall, 19 out of 21 trainees completed the clinical assessment and case presentation satisfactorilyConclusionThe Kirkpatrick framework served as a useful framework to perform the evaluation of the TEE program. The significant improvement in post-test scores, when compared with pre-test scores, suggested that the program is effective with regard to learning. As part of a multimodal pedagogy, simulation has proven to be an added value to our training program, and this was reflected by the improvement in the clinical assessment scores when compared to the pre-test scores. This result aligned with the concept of technology-enhanced learning in Education 4.0, where simulation in TEE training is applicable in the Malaysian context.

Effectiveness of innovative instructional module for professional competence in health literacy in medical students

BackgroundPhysicians should be equipped with professional competence in health literacy to communicate more effectively with patients with limited health literacy. However, the health literacy curriculum has not yet been refined globally, and is scarce in Taiwan’s medical education. We implemented an innovative instructional module to attain professional competence in health literacy among medical students and investigated its effects.MethodsWe adopted a quasi-experimental design and recruited 204 fifth-year Taiwanese medical students between December 2019 and May 2020. Participants who worked as clerks at the Department of Family Medicine of three medical schools in northern Taiwan were assigned to the experimental group through convenience sampling. A total of 98 students received a three-hour innovative instruction, including medical simulation videos, role-playing, and board games. Both the experimental and control groups completed the online pre-test and mail-in post-test. A generalized estimating equation was applied to measure the effects of the intervention.ResultsThere was a significant difference between the experimental and control groups in terms of professional competence in health literacy in all three aspects. In terms of knowledge, the experimental group improved 12% more than the control group (\U0001d6fd=0.12, 95% CI: 0.05 ~ 0.19, p = 0.001). In terms of attitude, the experimental group improved by an average of 0.27 more points per question than the control group (\U0001d6fd=0.27, 95% CI: 0.08 ~ 0.46, p = 0.007). As for skill, the experimental group improved by an average of 0.35 more points per question than the control group (\U0001d6fd=0.35, 95% CI: 0.14 ~ 0.55, p = 0.001).ConclusionThe proposed innovative instructional module significantly improved fifth-year medical students’ professional competence in health literacy, which is expected to benefit their future medical practices.

Cognitive and motor skill competence are different: Results from a prospective randomized trial using virtual reality simulator and educational video in laparoscopic cholecystectomy

Background and purposeCognitive transfer represents an important issue in surgical education. It is essential for the acquisition of competence, such as decision making and error avoidance. This randomized study aims to compare the effectivity of cognitive transfer by observing the surgery versus using modern virtual reality simulators for learning a laparoscopic cholecystectomy. MethodThis was a prospective, randomized, single centre study. 40 medical students from a university hospital, a tertiary care teaching institution, were enrolled. After a short introduction of laparoscopic cholecystectomy, they were randomized into two groups (video group and simulator group). In the video group, participants watched the step-by-step educational video twice. In the simulator group, participants underwent training using the virtual reality simulator, including tutorial procedural tasks of laparoscopic cholecystectomy as well as a complete cholecystectomy on the simulator. After the training, cognitive competence including decision making and error awareness was assessed using a questionnaire. ResultsIn the most critical step of laparoscopic cholecystectomy, “Dissection in Calot's triangle”, as well as in the aspect of planning next step, the video group was superior significantly (P = 0.038 and P = 0.04). No significant differences concerning the recognition of critical anatomical structures, choosing the necessary instruments as well as error awareness were found. ConclusionsLearning by watching a high-quality educational video is more effective in acquiring the cognitive competence to combine learned single tasks. Traditional learning means as watching educational videos and modern, sophisticated VRS should be deployed complementarily to establish cognitive and motor competencies separately.

Teaching Innovation in STEM Education Using an Unmanned Aerial Vehicle (UAV)

The use of unmanned aerial vehicles (UAVs) has increased in the science, technology, engineering, and mathematics (STEM) professions. This means there is a growing need to integrate UAV training into STEM education. This study aimed to develop and evaluate a UAV education module and laboratory exercise for natural resource science students. The study used a series of reusable learning objects (RLOs) to assess students’ prior knowledge of remote sensing and UAVs. Students were taught the steps of UAV data acquisition and processing through lectures and UAV simulation videos. Students applied this knowledge by completing a laboratory exercise that used previously collected UAV data. Student knowledge retention and understanding were evaluated using an online quiz to determine the effectiveness of the education module. The average quiz score was 92%, indicating that the UAV laboratory exercise effectively taught students about UAV data acquisition and processing for natural resource research. Overall, students expressed positive opinions about the UAV education module. Student feedback indicated that the laboratory exercise was engaging, but some students would have preferred a hands-on experience for some parts of the exercise. However, in-person UAV instruction may not be accessible for all educators because of UAV cost or lack of instructor training. This study provides educators with crucial recommendations for designing UAV exercises to improve access to UAV-related educational content. This study indicates that online training can effectively introduce students to UAVs. Given the wide range of UAV uses across STEM fields, students in many STEM disciplines would benefit from UAV education.

Public awareness of first-aid management of seizures in Saudi Arabia

BackgroundFirst aid measures in cases of epileptic seizures are crucial. Misconceptions about seizure first-aid measures are probably common. Most of the previous data focused on teachers and healthcare providers. The objective of this study was to assess the awareness of seizure first-aid measures and their associated factors in a community sample in Saudi Arabia. MethodsA cross-sectional study was carried out using an online questionnaire between July 2020 and February 2021. Those who had never heard of epilepsy and healthcare workers were excluded. Overall and individual scores were calculated for first-aid measures during and after the seizures as well as calling the ambulance. ResultsA total of 1542 participants were included in the study. The overall awareness score of seizure first-aid measures was 57.3%. The awareness of the need to call the ambulance in special circumstances was the highest individual score (78.3%), followed by measures after the seizure (54.2%), and finally measures during the seizure (48.4%). For the latter, the awareness of injury prevention measures was the highest (74.9%), while the awareness of treatment options was the lowest (12.2%). Overall awareness score was significantly higher in older age (p = 0.015), female gender (p < 0.001), divorced status (p = 0.014), knowing someone with epilepsy (p < 0.001), attending a course or workshop about seizure first-aid (p < 0.001), watching a video on seizure first-aid on any platform (p < 0.001), and having basic life support training (p < 0.001). ConclusionsThe awareness of seizure first-aid measures is still inadequate among the public in Saudi Arabia. The current finding underscores the importance of simulation videos on social media and/or field-training campaigns to improve the public awareness of seizure first-aid measures.

Patient mistreatment of health care professionals

BackgroundMistreatment of health care professionals by patients is an ongoing problem. We aimed to construct and evaluate a curriculum that would prepare health care professionals for mistreatment by patients.MethodsLessons learned from 15 interviews and 2 focus groups with health care professionals were distilled into a multi-modal curriculum including didactics, simulation videos and role-play scenarios aimed to improve confidence in addressing mistreatment. This curriculum was disseminated at five educational workshops to health care professionals of various training groups and experience levels. Pre- and post-surveys were distributed to assess changes in participant’s perspectives on readiness to address mistreatment. The signed-rank test was implemented to compare pre- and post- data.ResultsParticipants were more likely to agree post-workshop that they had the right words to say, had a plan for what to do, and were more willing to speak up when they themselves or someone else was mistreated (p < .001). They were also more likely to agree post-workshop that there was something they could do to address patient mistreatment (p < .001).ConclusionsParticipant familiarity and confidence in responding to patient mistreatment increased. Our curriculum may serve as a foundation for institutions seeking to equip their educators, health care professionals, and trainees with strategies for addressing this important issue.

Simulation-based education for medical radiation students: A scoping review.

Simulation‐based education is a significant aspect of teaching clinical skills in tertiary medical radiation science programmes, allowing students to experience the clinical setting in a safe environment. As an educational tool, simulation exists in many valid forms including role play, interprofessional simulation and virtual reality simulation. This scoping review looks at the current literature in this field to identify the evidence surrounding simulation‐based education for medical radiation students. The purpose of this review is to provide an evidence‐based guide for educators, identify gaps in the literature and suggest areas of future research. Data extraction was performed on 33 articles where the interventions could be categorised into either role play simulation, virtual simulation, simulation videos or online learning environments. Most studies demonstrated that simulation could improve clinical competence and increase preparedness and confidence for clinical placement. Student satisfaction remained high throughout the studies; however, it is the view of many that although simulation‐based education is a valid and effective tool, it is complementary to and not a replacement for clinical placement.

THE USE OF MOULAGE IN CLINICAL SIMULATION: MULTIPLE CASE STUDIES

Objective: identify how and why to use moulage within clinical simulation practices. Method: it is a multiple, inclusive, descriptive and exploratory case study with a qualitative approach. The cases were selected through an intentional sample. After applying the eligibility criteria, four cases of simulated scenarios that used moulage were included and analyzed. Results: all the cases analyzed were developed in extracurricular simulated clinical activities by facilitators with experience in clinical practices, teaching and simulation. The moulages used different techniques, promoting greater interaction with the learner through the use of stimulants of different sense organs, sharpening clinical reasoning, the development of skills, competences, among others. In the four cases, the moulage was performed on a simulated patient, in simulated scenarios and simulated video. The reasons described for moulage were: to provide realism, fidelity, easy application and low cost. Conclusion: it was possible to identify that the moulage is an adequate resource in clinical simulation and that when built with rigor and method, it influences the fidelity and realism of the simulated scenario.

Forensic evaluation of pedestrian injuries by FORTIS system and its significance for technical analysis of traffic accidents performed using simulation programs

BackgroundCurrently, simulation programs are used for a technical analysis of accidents including pedestrians as they provide a great amount of data on the physical parameters of the pedestrian’s body movement and its contacts with the vehicle or the road. In order to be able to make use of the presented options, it is necessary to obtain additional information about detected injuries from forensic doctors in a way utilizable for technical experts.MethodsThis study includes the results of 250 traffic accidents and approximately 200 real accidents, as well as 255 simulations. The evaluations were based on the investigation of circumstances, accompanying documentation, autopsy findings, photo documentation, and the results of additional expert examinations. We further proceeded in line with the complete autopsy findings in accordance with the requirements of the international classification of diseases.ResultsPrevious practice has shown that the modified forensic system FORTIS, due to its capability to parametrize through localization using the PC Fortis © program, is an important tool to supplement verbal descriptions and localizations of injuries that have been used so far.ConclusionsThe FORTIS system is a usable and universal means of supplementing verbal medical descriptions for the needs of traffic accident analysts with a scoring system of a high informative value. This, in combination with a video simulation of contacts with a pedestrian’s body during a collision and with values of physical parameters from simulation programs, makes it possible to significantly increase the value of evidence for the needs of the police and courts.
