The Effect of a Distributed Virtual Reality Simulation Training Program on Dissection Mastoidectomy Performance.

Temporal bone surgery requires excellent surgical skills and simulation-based training can aid novices' skills acquisition. However, simulation-based training is challenged by early stagnation of performance after few performances. Structured self-assessment during practice might enhance learning by inducing reflection and engagement in the learning task. In this study, structured self-assessment was introduced during virtual reality (VR) simulation of mastoidectomy to investigate the effects on subsequent performance during cadaveric dissection. A prospective educational study with comparison with historical controls (reference cohort). At a temporal bone dissection course, eighteen participants performed structured self-assessment during 3h of VR simulation mastoidectomy training before proceeding to cadaver dissection (intervention cohort). At a previous course, eighteen participants received identical VR simulation training but without the structured self-assessment (reference cohort). Final products from VR simulation and cadaveric dissection were recorded and assessed by two blinded raters using a 19-point modified Welling Scale. The intervention cohort completed fewer procedures (average 4.2) during VR simulation training than the reference cohort (average 5.7). Nevertheless, the intervention cohort achieved a significantly higher average performance score both in VR simulation (11.1 points, 95% CI [10.6-11.5]) and subsequent cadaveric dissection (11.8 points, 95% CI [10.7-12.8]) compared with the reference cohort, who scored 9.1 points (95% CI [8.7-9.5]) during VR simulation and 5.8 points (95% CI [4.8-6.8]) during cadaveric dissection. Structured self-assessment is a valuable learning support during self-directed VR simulation training of mastoidectomy and the positive effect on performance transfers to subsequent cadaveric dissection performance.

The objective of this paper is to describe the current status, advantages, and disadvantages of Virtual Reality simulators as tools for training and assessment of laparoscopic skills. This is a review of publications about Virtual Reality simulators in laparoscopic training and assessment. Information was obtained through author’s experience and by search of MEDLINE using the keywords Virtual Reality simulation, training, assessment and laparoscopic surgery. The references cited in these studies were reviewed to find out whether any other trials fitted the selection criteria. There are several validated Virtual Reality systems that allow the transfer of skills from the virtual environment to the operating room and objective assessment of operative skills in laparoscopic surgery. In conclusion, Virtual Reality simulators are valid and objective tools in surgical education. Several systems are currently considered sufficiently validated and ready to be implemented in comprehensive educational curricula in minimally invasive surgery.

Cochlear implantation requires excellent surgical skills; virtual reality simulation training is an effective method for acquiring basic competency in temporal bone surgery before progression to cadaver dissection. However, cochlear implantation virtual reality simulation training remains largely unexplored and only one simulator currently supports the training of the cochlear implantation electrode insertion. Here, we aim to evaluate the effect of cochlear implantation virtual reality simulation training on subsequent cadaver dissection performance and self-directedness. This was a randomized, controlled trial. Eighteen otolaryngology residents were randomized to either mastoidectomy including cochlear implantation virtual reality simulation training (intervention) or mastoidectomy virtual reality simulation training alone (controls) before cadaver cochlear implantation surgery. Surgical performance was evaluated by two blinded expert raters using a validated, structured assess- ment tool. The need for supervision (reflecting self-directedness) was assessed via post-dissection questionnaires. The intervention group achieved a mean score of 22.9 points of a maximum of 44 points, which was 5.4% higher than the control group's 21.8 points (P = .51). On average, the intervention group required assistance 1.3 times during cadaver drilling; this was 41% more frequent in the control group who received assistance 1.9 times (P = .21). Cochlear implantation virtual reality simulation training is feasible in the context of a cadaver dissection course. The addition of cochlear implantation virtual reality training to basic mastoidectomy virtual reality simulation training did not lead to a significant improvement of performance or self-directedness in this study. Our findings suggest that learning an advanced temporal bone procedure such as cochlear implantation surgery requires much more training than learning mastoidectomy.

The effectiveness of virtual reality (VR) simulation training for improving robotic surgical skills is not firmly established. This systematic review and meta-analysis aimed to evaluate the impact of VR simulator training on surgeons' robotic surgical performance in the operating room (OR). To synthesize evidence regarding the association between VR-based robotic surgery training and subsequent technical performance inside the OR. A comprehensive literature search was conducted in PubMed, Scopus, Embase, and CINAHL databases, adhering to PRISMA 2020 guidelines. Studies evaluating VR simulator training for robotic surgeons with subsequent performance assessment in the OR were included. Risk of bias assessment was performed using the Medical Education Research Study Quality Instrument and the modified Newcastle-Ottawa Scale for Education (NOS-E), along with funding source appraisal. A total of 294 records were screened, resulting in 13 studies (281 participants) included in the systematic review, and 4 studies (72 participants) suitable for meta-analysis. Metaanalysis was conducted using a random-effects model to pool correlation coefficients between preand post-training performance. Of the included studies, nine reported positive evidence, three found no evidence, and one found negative evidence regarding VR training's role. The meta-analysis of before-after studies revealed a significant positive correlation ( r = 0.717, P < 0.05) between simulation performance and intraoperative outcomes. The small number of studies included in the meta-analysis and methodological heterogeneity may limit generalisability of results. VR simulator training is associated with improved robotic surgical performance in the OR. Incorporation of VR simulation into robotic surgical curricula is likely beneficial for skill acquisition and operative readiness.

Operating room (OR) fires are rare but devastating events requiring immediate and effective response. Virtual Reality (VR) simulation training can provide a safe environment for practice of skills in such highly stressful situation. This study assessed interprofessional participants' ability to respond to VR-simulated OR fire scenarios, attitudes, numbers of attempt of the VR simulation do participants need to successfully respond to OR fires and does prior experience, confidence level, or professional role predict the number of attempts needed to demonstrate safety and pass the simulation. 180 surgical team members volunteered to participate in this study at Beth Israel Deaconess Medical Center, Boston, MA. Each participant completed five VR OR simulation trials; the final two trials incorporated AI assistance. Primary outcomes were performance scores, number of attempts needed to pass, and pre- and post-survey results describing participant confidence and experiences. Differences across professional or training role were assessed using chi-square tests and analyses of variance. Differences in pass rates over time were assessed using repeated measures logistic regression. One hundred eighty participants completed simulation testing; 170 (94.4%) completed surveys. Participants included surgeons (17.2%), anesthesiologists (10.0%), allied health professionals (41.7%), and medical trainees (31.1%). Prior to training, 45.4% of participants reported feeling moderately or very confident in their ability to respond to an OR fire. Eight participants (4.4%) responded safely on the first simulation attempt. Forty-three participants (23.9%) passed by the third attempt (VR only); an additional 97 participants (53.9%) passed within the 4-5th attempt (VR with AI assistance). Providers are unprepared to respond to OR fires. VR-based simulation training provides a practical platform for individuals to improve their knowledge and performance in the management of OR fires with a 79% pass rate in our study. A VR AI approach to teaching this essential skill is innovative, feasible, and effective.

Virtual reality simulation in training endoscopic skills: A systematic review

Virtual reality (VR) offers the potential to provide a lifelike, safe, and interactive environment where healthcare providers can practice and refresh their skills. The Neonatal Resuscitation Program (NRP) is an evidence-based and standardized approach for training healthcare providers on the resuscitation of the newborn where VR can be applied. Here we describe a development study for a VR-NRP simulation. This contribution is relevant for researchers and developers in the health sector interested in the integration of VR and other extended reality (XR) technologies in medical education and training. For the implementation of the VR simulation, we used the Unity game engine, a VR-capable laptop, and an HTC Vive Pro Head-Mounted Display. We focused on the skill of positive pressure ventilation (PPV) using a bag and mask as the main scenario for the simulation since this is a foundational skill in NRP. To validate the prototype, we compared the VR-NRP simulation with 360° immersive VR videos in a crossover study involving 30 health-care providers and students, collecting various data through questionnaires and skill assessments by NRP instructors. We described in detail the creation process by which a highly realistic VR simulation was produced reflecting the visual elements and sounds of a Neonatal Intensive Care Unit in a hospital setting. In the crossover study, we found both VR technologies were positively viewed by healthcare professionals and performed very similarly. However, the VR simulation provided a significantly increased feeling of presence. Participants found the VR simulation more useful and reported higher confidence in NRP skills such as proper mask placement and newborn response evaluation, reflecting improved experiential learning outcomes. This research represents a step forward in understanding how VR technologies can be developed and applied for effective, immersive medical training, increasing the availability of NRP refresher sessions, and providing insights into similar applications.

Extended-Reality Technologies: An Overview of Emerging Applications in Medical Education and Clinical Care.

There is limited data assessing simulation and virtual reality training as a standardized tool in medical education. This feasibility study aimed to evaluate the effectiveness of virtual reality training and a student-led simulation module in preparing medical students to perform a lumbar puncture. Twenty-five medical students completed a pre-intervention survey, and a baseline video recorded lumbar puncture procedure on a task trainer. Students were randomly distributed into the virtual reality group, or the curriculum's standard student-led procedural instruction group. Participants were then given 45min to practice the lumbar puncture procedure. After the intervention, all participants were video recorded again as they performed a post-intervention lumbar puncture and completed a post-intervention survey. Pre- and post-intervention videos were scored using a critical action checklist in conjunction with time needed to complete the procedure to evaluate proficiency. At baseline, there were no major statistically significant differences between groups. Assessing overall post-intervention performance, both groups showed improvement in aggregate score (p < 0.001) and time required to complete (p = 0.002) the lumbar puncture. Following interventions, the student-led group improved over the virtual reality group in a variety of metrics. The student-led group increased their aggregate score by 3.49 and decreased their time to completion by 34s over the VR group when controlling for baseline measures. Both virtual reality and student-led simulation training were useful training modalities, with hands-on simulation showing better results versus virtual reality training in this setting.

This article focuses on the effectiveness of virtual reality (VR) simulation training for intravenous (IV) cannulation. We analyzed the learning process in skills acquisition from groups with limited experience in comparison with the performance of experts. Novices (n = 20) and intermediates (n = 23) trained on nine IV cannulation scenarios with a high-fidelity VR simulator (Virtual IV). Another three scenarios were performed before and after training (pre- and postassessment). Pre-/postassessment was also undertaken by a group of 10 experts for comparative evaluation. Performance metrics included the completion time and an error score that was obtained after quantitative analysis of the errors committed during training. The learning curves were evaluated by recording the number of attempts required to successfully perform each training scenario. A performance was considered successful when the error score was below a predetermined threshold. The learning curves of intermediates and novices demonstrated a clear plateau at the sixth and eighth scenario, respectively. These plateaus were reached after 15 (intermediates) and 23 (novices) attempts. There was a highly significant reduction in the time and errors between pre- and postassessment (P < 0.01). Before training, the performance (errors, time) of the three groups was significantly different to one another (novices: lowest, experts: highest, P < 0.05). After training, the performance of intermediates and novices was equivalent to that of the experts (P > 0.1). Intermediates committed fewer critical and more noncritical errors than novices, and vice versa (P < 0.05). Simulation training enhanced the skills of inexperienced subjects significantly. The VR simulator demonstrated construct validity for three different levels of experience. The number of attempts over a series of equal difficulty scenarios provides a valuable alternative to the traditional measures of the learning curve.
