Computerized Suicide Prevention Clinical Training Simulations: A Pilot Study.

Purpose: Mental health providers are well-positioned to engage in suicide prevention efforts, yet implementation depends on skill acquisition and providers often report feeling underprepared. This pilot study explored the acceptability, feasibility, and preliminary effectiveness of three suicide prevention-focused simulations with virtual clients. Method: Students (n=22) were recruited from a MSW program, completed pre- and post-test surveys, and engaged with three simulated trainings: 1) suicide risk assessment, 2) safety planning, and 3) motivating a client to treatment. Results: Simulations were reported to be acceptable and feasible, with strong student desire and need for greater suicide prevention training. We observed significant improvements over time in clinical skills via simulated training scores and perceptions of clinical preparedness. Discussion: Preliminary findings indicate simulated training with virtual clients is promising and suggest the three suicide prevention simulations may be useful, scalable, and effective in social work training programs and beyond.

Effect of preoperative patient education and simulated mouth breathing training on opioid requirements in the post-anesthesia care unit after nasal surgery: a randomized controlled study.

BACKGROUND: A simulated education, prior to surgery about postoperative nasal stuffiness and ease of breathing through the mouth may help patients tolerate discomfort after nasal surgery. This study aimed to investigate the effect of preoperative simulated education on immediate postoperative opioid requirements in patients undergoing elective nasal surgery. METHODS: This randomized controlled trial of 110 patients undergoing nasal surgery randomly allocated patients into either a control (group C) or an education group (group E). One day before surgery, patients in group E were intensively trained to breathe through the mouth by using a nasal clip, with informative explanations about inevitable nasal obstruction and discomfort following surgery. Patients in group C were provided with routine preoperative information. Total intravenous anesthesia (TIVA) with propofol and remifentanil was used for anesthesia. No further opioid was used for analgesia intraoperatively. The primary outcome was index opioid (fentanyl) requirements at the post-anesthesia recovery unit (PACU). Secondary outcomes were emergence agitation, pain scores at the PACU, and postoperative recovery using the Quality of Recovery-15 (QoR15-K). RESULTS: The rate of opioid use in the PACU was 51.0% in the group E and 39.6% in the group C (p = 0.242). Additional request for analgesics other than index opioid was not different between the groups. Emergence agitation, postoperative pain severity, and QoR15-K scores were comparable between the groups. CONCLUSION: Preoperative education with simulated mouth breathing in patients undergoing nasal surgery did not reduce opioid requirements.

Condition Monitoring of Ball Bearings Based on Machine Learning with Synthetically Generated Data.

Rolling element bearing faults significantly contribute to overall machine failures, which demand different strategies for condition monitoring and failure detection. Recent advancements in machine learning even further expedite the quest to improve accuracy in fault detection for economic purposes by minimizing scheduled maintenance. Challenging tasks, such as the gathering of high quality data to explicitly train an algorithm, still persist and are limited in terms of the availability of historical data. In addition, failure data from measurements are typically valid only for the particular machinery components and their settings. In this study, 3D multi-body simulations of a roller bearing with different faults have been conducted to create a variety of synthetic training data for a deep learning convolutional neural network (CNN) and, hence, to address these challenges. The vibration data from the simulation are superimposed with noise collected from the measurement of a healthy bearing and are subsequently converted into a 2D image via wavelet transformation before being fed into the CNN for training. Measurements of damaged bearings are used to validate the algorithm's performance.

Randomised simulation trial found an association between rescuers' height and weight and chest compression quality during paediatric resuscitation.

AIM: Our aim was to examine the relationship between rescuers' anthropometric data and chest compression quality during paediatric resuscitation training. METHODS: This study focused on 224 medical students (53% women) who performed 2 minutes of paediatric resuscitation at the Medical University of Vienna, Austria: 116 on a baby manikin and 108 on an adolescent manikin. Skill Reporter software measured chest compression quality by recording compression depth, frequency, hand position and complete recoil. The participants' height, weight and body mass index (BMI) were recorded. RESULTS: Participants with a lower BMI achieved higher total chest compression scores on both the baby and adolescent manikins than participants with a higher BMI. The latter were more likely to exceed the correct compression depth and not achieve complete chest recoil in the adolescent manikin. When it came to the baby manikin, the female participants achieved better chest recoil and the males achieved a higher number of compressions at the correct rate. Males also achieved better chest recoil with the adolescent manikins. Being tall only correlated with incomplete recoil in the adolescent manikin. CONCLUSION: The results indicate that anthropometric variables were associated with chest compression quality in paediatric patients and should be considered by future education programmes.

Endoscopic surgery: talent or training?

PURPOSE: There are two groups of undergraduate students involved in endoscopic surgery with different degrees of experience: average and more experience. This study proves whether the subjective impression of the laparoscopic trainer is verifiable and which factors influence extreme talent. METHODS: 21 medical students of the eighth term of the University of Witten-Herdecke participated in the study. On their first course day, students got instructed in suturing and knot technique. They were then required to tie a maximum of five knots within 2 h. After a week, students repeated this procedure. Time used for tying knots was stopped. RESULTS: Regarding the time students used for their first knots, great differences were provable (7-8 min, average 23 min). However, an adaption of the knotting time was noticed at the end of the first course day. This was confirmed during the second course day. Neither acquired factors (music, sport, etc.) nor individual factors (visual acuity, handedness, etc.) had any impact on the time used for knotting. Merely, one advantage was seen with the first knots with the factors of playing the guitar and having a more than 10-h surgical previous experience. Knotting times leveled off at 95% to less than 10 min, though. DISCUSSION: Neither normally talented nor extremely talented junior surgeons could be noticed, and so could not the co-factors providing an advantage or disadvantage for surgery, respectively. All prospective surgeons can learn defined tasks (knots) by short interval training, and thus show similarly good results after a few repetitions.

Simulated training program in abdominal paracentesis for undergraduate medical students.

BACKGROUND AND AIMS: Abdominal paracentesis is an area that every general physician should know about, and the current learning model is unsafe for patients. Simulation allows students to develop their skills prior to clinical confrontation with minimal risks. The aims of this study were to design and evaluate a paracentesis simulation workshop for undergraduate students. METHODS: A workshop was implemented using a specially designed and validated simulation model for abdominal paracentesis. The simulated technique considered the recognition of materials, operator equipment, asepsis, anesthesia, puncture and obtaining liquid, collecting samples for analysis, withdrawal of the material and occlusion. A 24-point direct observation checklist was administered to assess the student. We assessed two students at the beginning of the workshop and all the students at the end. A perception survey was applied to attendees at the end of the workshop. RESULTS: 247 students were included and a workshop that involved 8 students per session was held. Students significantly improved their skills comparing pre- and post-evaluation results [13.36±4.46 (55.7%) vs. 22.3±1.83 (92.9%) respectively (n=69) p<0.001]. The students' perception questionnaire (n=38) showed that the training sessions were highly valued, averaging 4.8±0.38 on a Likert scale of 1-5. CONCLUSIONS: Simulated training in abdominal paracentesis is a very good teaching method. This teaching methodology should be highly recommended as an educational strategy in medicine because it could accelerate the acquisition of clinical skills in a safe learning environment.

Teaching hypospadias repair by utilising a novel 3D-printed silicon model: An initial assessment using structured trainee and trainer feedback.

INTRODUCTION: Simulated paediatric surgical training is inherently advantageous and flourishing. Moreover, several working conditions resulted in reduced training hours, index and subspecialty cases encountered, and the COVID-19 pandemic affected elective surgery backlogs, hence training opportunities. Hypospadias repair is technically-demanding and requires a spectrum of dissective and reconstructive skills. We therefore aimed to test a 3D-printed silicon model for hypospadias repair, in the context of hands-on surgical training. MATERIAL AND METHODS: Twenty-Seven trainees, under the supervision of 15 instructors, completed the activity. They were given a seminar to show the relevant anatomy, and 8 key steps of the exercise: (1)-degloving; (2)-urethral plate marking; (3)-incision; (4)-tubularisation; (5)-glansplasty/glanuloplasty; (6)-dartos layer preparation; (7)-preputioplasty and (8)-skin closure. Each trainee completed a structured feedback assessment. An on-site trainer supervised and evaluated each exercise. Trainees and trainers rated the model through the above steps from unsatisfactory-(1/5) to excellent-(5/5), presented herein via cross-sectional analysis. RESULTS: Eleven-(40.7 %) trainees were in years:1-3 of specialist training, 10-(37 %) were in years:4-6, and 6-(22.2 %) were beyond year-6. Two-(7.4 %) trainees had nil-hypospadias experience, 16-(59.2 %) previously assisted in procedures or performed steps, 5-(18.5 %) performed whole procedures supervised and 4-(14.8 %) independently. Twenty-(74 %) trainees and 15-(100 %) instructors judged the model to resemble the anomaly. Seventeen-(63 %) trainees and 13-(86.6 %) instructors rated the material needle-penetrability ≥3/5, compared to human tissue. Sixteen-(59 %) trainees and 13-(86.6 %) instructors rated the material suture holding ≥3/5. Eleven-(73.3 %) trainees and 13-(86.6 %) instructors rated sutures' evenness and edge coaptability ≥3/5. DISCUSSION: Hypospadias is an index operation, which requires precision skills. Simulated training in Paediatric Surgery and Urology is gaining importance. 3D-printed models are gaining a key role in simulated training. The study presents a novel 3D-printed high-fidelity silicon-based hypospadias model designed for hands-on training. A structured pathway to divide a standard hypospadias repair into key steps is displayed to ensure skill acquisition and stabilisation. CONCLUSION: This 3D-printed silicon-based hypospadias model is proven useful for hands-on training. The fidelity can still improve, especially regarding suture holding of the material. LEVEL OF EVIDENCE: LEVEL III.

Narrative and Behavioral Engagement as Indicators for the Effectiveness of Intentionally Designed Virtual Simulations of Interpersonal Interactions.

Interventions involving simulated interactions aimed at mimicking real situations must be engaging to maximize their effectiveness. This study aimed to assess how a sample of middle school girls displayed behavioral and cognitive indicators of engagement when interacting with avatars representing game characters that were controlled by a human digital puppeteer. The simulation game, DRAMA-RAMA, is a component of an intervention intended to reduce at-risk girls' sexual and other risky behaviors. We used verbal/nonverbal behaviors and surveys to assess the game players' cognitive and behavioral involvement (N = 131). Participants perceived the game scenarios and interactions as realistic and the characters as similar to people in real life. Participants' behavior indicated their involvement and interest in interacting with the game characters. Finally, participants tended to be appropriate but not effective when attempting to advise/support the characters. These findings have implications for assessing successful operationalization of communication designs in interactive virtual learning environments.

Dye-Perfused Human Placenta for Simulation in a Microsurgery Laboratory for Plastic Surgeons.

In recent decades, a number of simulation models for microsurgical training have been published. The human placenta has received extensive validation in microneurosurgery and is a useful instrument to facilitate learning in microvascular repair techniques as an alternative to using live animals. This study uses a straightforward, step-by-step procedure for instructing the creation of simulators with dynamic flow to characterize the placental vascular tree and assess its relevance for plastic surgery departments. Measurements of the placental vasculature and morphological characterization of 18 placentas were made. After the model was used in a basic microsurgery training laboratory session, a survey was given to nine plastic surgery residents, two microsurgeons, and one hand surgeon. In all divisions, venous diameters were larger than arterial diameters, with minimum diameters of 0.8 and 0.6 mm, respectively. The majority of the participants considered that the model faithfully reproduces a real microsurgical scenario; the consistency of the vessels and their dissection are similar in in vivo tissue. Furthermore, all the participants considered that this model could improve their surgical technique and would propose it for microsurgical training. As some of the model's disadvantages, an abundantly thick adventitia, a thin tunica media, and higher adherence to the underlying tissue were identified. The color-perfused placenta is an excellent tool for microsurgical training in plastic surgery. It can faithfully reproduce a microsurgical scenario, offering an abundance of vasculature with varying sizes similar to tissue in vivo, enhancing technical proficiency, and lowering patient error.

NeXtQSM-A complete deep learning pipeline for data-consistent Quantitative Susceptibility Mapping trained with hybrid data.

Deep learning based Quantitative Susceptibility Mapping (QSM) has shown great potential in recent years, obtaining similar results to established non-learning approaches. Many current deep learning approaches are not data consistent, require in vivo training data or solve the QSM problem in consecutive steps resulting in the propagation of errors. Here we aim to overcome these limitations and developed a framework to solve the QSM processing steps jointly. We developed a new hybrid training data generation method that enables the end-to-end training for solving background field correction and dipole inversion in a data-consistent fashion using a variational network that combines the QSM model term and a learned regularizer. We demonstrate that NeXtQSM overcomes the limitations of previous deep learning methods. NeXtQSM offers a new deep learning based pipeline for computing quantitative susceptibility maps that integrates each processing step into the training and provides results that are robust and fast.

Role of Simulated Training for Carotid Endarterectomy: A Systematic Review.

Vascular surgery trainees often do not get to perform carotid endarterectomy (CEA) directly on the patients as it requires meticulous surgical technique and has a high risk of procedure-related complications. Hence, the role of simulation in training future vascular surgeons becomes essential. This review aims to assess the types and utility of simulators available for CEA. In this systematic review, all the studies performed on CEA simulation were included. The purpose of this review was to assess different types of simulators and their usefulness for CEA. We identified 122 articles, of which 10 were eligible for review. A variety of simulators, ranging from animal models, virtual reality simulators and commercially designed models with high fidelity options were used. Technical competence was the major domain assessed in the majority of the studies (n=8), whereas four studies evaluated anatomical and procedural knowledge. Blinding was done in five studies for assessment purposes. The majority of studies (n=9) found the simulation to be an effective tool for achieving technical competence. This review shows the potential usefulness of simulation in acquiring technical skills and procedural acumen for CEA. The available literature is unfortunately too diverse to have a common recommendation.

A Systematic Review of the Medical Student Feedback on Undergraduate Surgical Education During the Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has challenged and changed significant aspects of day-to-day life. With regard to medical education, the challenges have been substantial, and the changes have been innovative. This systematic review focuses specifically on medical student feedback on undergraduate surgical education during the pandemic. It explores the various types of technology used to facilitate online learning and aims to comprehensively review the advantages and disadvantages. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were adhered to, and electronic databases PubMed, Medline, and Scopus were used to identify relevant studies. The search yielded 102 papers once duplicates and non-English articles were removed. Of these, 19 articles were included in the review. These publications were appraised, which was the source of the narrative syntheses of this systematic review, and due to the heterogeneous data, a meta-analysis could not be successfully implemented. The integration of real-time image capture devices used to display stakeholders or objects such as models of wounds has resulted in the improvement of virtual learning to an almost in-person experience. Adding to this, the use of communication and participation platforms facilitates active discussion when used appropriately. However, there are still some barriers that may be removed with time as the technology continually improves, and these are not exclusive to connectivity issues and restriction of the senses to only two-dimensional sight and hearing. Despite this, the student feedback was largely positive, and the integration of more innovative methods of delivering teaching will have a positive impact on education as long as it is used as an adjunct and not as a replacement for face-to-face teaching.

Sensor-based indicators of performance changes between sessions during robotic surgery training.

Training of surgeons is essential for safe and effective use of robotic surgery, yet current assessment tools for learning progression are limited. The objective of this study was to measure changes in trainees' cognitive and behavioral states as they progressed in a robotic surgeon training curriculum at a medical institution. Seven surgical trainees in urology who had no formal robotic training experience participated in the simulation curriculum. They performed 12 robotic skills exercises with varying levels of difficulty repetitively in separate sessions. EEG (electroencephalogram) activity and eye movements were measured throughout to calculate three metrics: engagement index (indicator of task engagement), pupil diameter (indicator of mental workload) and gaze entropy (indicator of randomness in gaze pattern). Performance scores (completion of task goals) and mental workload ratings (NASA-Task Load Index) were collected after each exercise. Changes in performance scores between training sessions were calculated. Analysis of variance, repeated measures correlation, and machine learning classification were used to diagnose how cognitive and behavioral states associate with performance increases or decreases between sessions. The changes in performance were correlated with changes in engagement index (rrm=-.25,p<.001) and gaze entropy (rrm=-.37,p<.001). Changes in cognitive and behavioral states were able to predict training outcomes with 72.5% accuracy. Findings suggest that cognitive and behavioral metrics correlate with changes in performance between sessions. These measures can complement current feedback tools used by medical educators and learners for skills assessment in robotic surgery training.

Assessment of Informed Consent and the Impact of Simulation on Anesthesia Trainees.

Introduction Over the years, the process of obtaining informed consent has evolved and now places an emphasis on the concept that patients should play a major role in medical decision making. Failure to adequately involve patients in making decisions regarding their health can lead to medicolegal consequences. Therefore, taking informed consent is a fundamental component of anaesthesia training. Simulation, for training, is an excellent tool that is being utilised widely in the training of medical professionals. The use of simulated training for teaching the process of informed consent is an innovative initiative that can provide improved results. Material and methods After approval from the institutional review board, a prospective clinical study was conducted at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, from August 2019 to September 2020. Sixteen anaesthesia trainees were randomly selected for the study. The study was divided into pre-interventional, interventional and post interventional phases. For data collection, a predesigned checklist was used. Data collected was analysed using SPSS version 23 (IBM Inc., Armonk, New York). The McNemar test was deployed to assess the difference between the baseline assessment and post-simulated training assessment; p-value < 0.05 was taken to be significant. Results Of the 16 participants, the majority were males (n= 13). A positive impact was observed in terms of improvement of the outcome of the following study components i.e., description of benefits of the procedure (p=0.01), disclosure of associated minor risks (p=0.005), disclosure of major risks (p=0.01), discussion of alternatives (p=0.001), teach back (p=0.001), documentation of patients' verbal agreement (p=0.01), and communication skills involving utilising the process of connecting, introduction, communication, permission, response, and exit (p = 0.01). Conclusion Simulated training had a positive impact in improving outcomes in the following study components: description of benefits of the procedure, disclosure of associated risks, discussion of alternatives, teach back, documentation of patients' verbal agreement, and utilisation of the process of connecting, introduction, communication, permission, responding, and exiting.

Endoscopic Management of Cavernous Carotid Surgical Complications: Evaluation of a Simulated Perfusion Model.

OBJECTIVE: Endoscopic surgical treatment of pituitary tumors, lateral invading tumors, or aneurysms requires surgeons to operate adjacent to the cavernous sinus. During these endoscopic endonasal procedures, the carotid artery is vulnerable to surgical injury at its genu. The objective of this simulation model was to evaluate trainees regarding management of a potentially life-threatening vascular injury. METHODS: Cadaveric heads were prepared in accordance with the Oregon Health & Science University body donation program. An endoscopic endonasal approach was used, and a perfusion pump with a catheter was placed in the ipsilateral common carotid artery at its origin in the neck. Learners used a muscle graft to establish vascular control and were evaluated over 3 training sessions. Simulation assessment, blood loss during sessions, and performance metric data were collected for learners. RESULTS: Vascular control was obtained at a mean arterial pressure of 65 mm Hg using a muscle graft correctly positioned at the arteriotomy site. Learners improved over the course of training, with senior residents (n = 4) performing better across all simulation categories (situation awareness, decision making, communications and teamwork, and leadership); the largest mean difference was in communication and teamwork. Additionally, learner performance concerning blood loss improved between sessions (t = 3.667, P < 0.01). CONCLUSIONS: In this pilot endoscopic endonasal simulation study, we successfully demonstrate a vascular complication perfusion model. Learners were able to gain direct applicable expertise in endoscopic endonasal techniques, instrumentation use, and teamwork required to optimize the technique. Learners gained skills of vascular complication management that transcend this model.

Objective: To examine the available evidence on the perception of course participants as a training scenario for non-technical skills. Methods: A literature review was conducted between October 2020 and May 2021. The terms used in non-technical skills were identified, they became MeSH terms. It was conducted an advanced search of the PUBMED and ERIC databases. Analysis and synthesis of information: 11 articles that describe the perceptions of doctors, pediatricians and nurses about the characteristics of an effective leader, factors that influence coordinated teamwork, the importance of effective communication and having an adequate awareness of the situation in different resuscitation scenarios such as trauma, emergencies and critical care were reviewed; and, the recommendations of the participants on simulation as a learning tool of these skills. Conclusions: Non-technical skills grouped in the categories of leadership, communication, teamwork and situational awareness, are perceived as a fundamental pillar in the functioning and outcome of cardiopulmonary resuscitation(AU)

Validación de un simulador para el entrenamiento de la capsulotomía posterior láser en oftalmología / Validation of a simulator for teaching posterior capsulotomy with laser in ophthalmology

Introducción: La capsulotomía láser representa el único tratamiento efectivo para tratar la opacidad de cápsula posterior -causa más común de disminución de la visión después de una cirugía de catarata-. Este proceder es sencillo, pero no exento de complicaciones. Hasta ahora su aprendizaje se realiza directamente en los pacientes. El uso de simuladores permite el aprendizaje de la técnica sin dañar al paciente y sin la obligada presencia del profesor. Objetivo: Validar la confección de un modelo de ojo artificial como simulador para el entrenamiento de residentes de oftalmología en capsulotomía posterior con láser. Métodos: Estudio observacional, descriptivo y prospectivo en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer", realizado desde febrero hasta marzo de 2019. Se confeccionó un modelo que simula el ojo pseudofáquico con opacidad de cápsula posterior. Se eligieron ocho residentes de oftalmología de primer año que nunca habían realizado una capsulotomía láser. Todos observaron la ejecución de la capsulotomía en pacientes reales y en el modelo docente, mientras recibían la explicación de la técnica. Posteriormente, cada estudiante efectuó el proceder sobre el simulador en tres ocasiones, y se evaluó en cuanto al completamiento de la capsulotomía y los impactos al lente. Resultados: Se obtuvo un modelo de simulación para el entrenamiento de la capsulotomía posterior láser con el uso de materiales reusables. El promedio de disparos para completar el proceder fue superior al necesario en pacientes reales. No obstante, el número de disparos e impactos de láser en el lente intraocular se redujo con las sucesivas sesiones de entrenamiento. Conclusiones: El simulador confeccionado es económico y de fácil factura. Su uso resulta funcional para el entrenamiento sistemático de la capsulotomía posterior con Nd. YAG láser, sin riesgo de daño para el paciente. Contribuye a perfeccionar el enfoque y a minimizar los impactos en la lente intraocular, por lo que se muestra como un medio didáctico útil para la formación y evaluación de habilidades de los residentes de oftalmología(AU)

Introduction: Laser capsulotomy is the only effective treatment for posterior capsule opacity, the commonest cause of decreased vision after cataract surgery. This procedure is simple, but not without complications. Until now, learning such procedure has been carried out directly on patients. Using simulators allows learning the technique without harming patients and without the professor's obligatory presence. Objective: To validate the creation of an artificial eye model to be used as a simulator for the training of Ophthalmology residents in posterior capsulotomy with laser. Methods: Observational, descriptive and prospective study carried out, from February to March 2019, at Ramón Pando Ferrer Cuban Institute of Ophthalmology. A model was made that simulates the pseudophakic eye with posterior capsule opacity. Eight first-year Ophthalmology residents who had never performed a laser capsulotomy were selected. All the participants observed the performance of capsulotomy in real patients, as well as in the teaching model, while receiving the explanation regarding the technique. Subsequently, each student performed the procedure with the simulator on three occasions, and received an evaluation based on the completion of the capsulotomy and the impacts to the lens. Results: A simulation model was obtained for training posterior laser capsulotomy with the use of reusable materials. The average number of shots to complete the procedure was higher than necessary in real patients. However, the number of shots and laser impacts on the intraocular lens decreased with successive training sessions. Conclusions: The simulator created is cheap and easy to make. Its use is functional for the systematic training of posterior capsulotomy with neodymium. Yttrium aluminium garnet (YAG) laser did not have any risks to the patient. It contributes to perfecting the focus and minimizing the impacts on the intraocular lens; therefore, it is shown as a useful didactic means for the training and evaluation of skills of Ophthalmology residents(AU)
