Clinical evidence

This study addresses the challenges of ultrasound education in obstetrics and gynecology, focusing on the potential benefits of simulation techniques in medical training. Aiming to evaluate the impact of a structured simulator-based training program, this prospective, randomized, interventional study examines its effects on educational outcomes for 5th year medical students.

Our data have demonstrated that arthroscopic skills can be taught effectively on a simulator, but a 10-h course is not sufficient to reach the target level set by experienced arthroscopists. However, learning progress can be monitored more objectively during simulator training than in the operating room, and simulation may partially replace the current practice of arthroscopic training.

This study suggests that surgical simulation training is well accepted and even demanded among surgical residents as an alternative training solution able to address some of the limitations and challenges of the current one-to-one apprenticeship model. There is a wide variation among the residents regarding the number of training hours required, underscoring the need for structured performance-based simulator training.

The results of this study indicate good validity and reliability of DASS for the assessment of the surgical performance of diagnostic knee arthroscopy during simulator training. Standardized training is recommended before arthroscopy surgery is considered in patients.

Virtual reality (VR) simulation is particularly suitable for learning arthroscopy skills. Despite significant research, one drawback often outlined is the difficulty in distinguishing performance levels (Construct Validity) in experienced surgeons. Therefore, it seems adequate to search new methods of performance measurements using probe trajectories instead of commonly used metrics.

There are few studies that compare the cadaver dissections with the medical simulators in means of talent improvement. Therefore, the aim of this study is to find out if using cadaver dissections is still the golden standard for surgical training or using the medical simulators in surgery could replace cadaver dissections

Module-based simulation training provides additional training time and improves technical skills in naive health science students. It is hoped that this effect can be preserved and applied to junior resident developing in a busy residency program.

Virtual Reality (VR) simulators are playing an increasingly prominent role in orthopaedic training and education. Face-validity - the degree to which reality is accurately represented - underpins the value of a VR simulator as a learning tool for trainees. Despite the importance of tactile feedback in arthroscopy, there is a paucity for evidence regarding the role of haptics in VR arthroscopy simulator realism.

The aim of this study was to investigate whether acquiring basic knee arthroscopic skills via a spaced retraining schedule could prevent skills deterioration and achieve further skills improvement.

Most studies demonstrated, that training on a virtual reality based arthroscopy simulator leads to an improvement of technical skills in orthopaedic surgery. However, how long and what kind of training is optimal for young residents is unknown. In this study we tested the efficacy of a standardized, competency based training protocol on a validated virtual reality based knee- and shoulder arthroscopy simulator.

Purpose: To validate the knee, shoulder, and virtual Fundamentals of Arthroscopic Training (FAST) modules on a virtual arthroscopy simulator via correlations with arthroscopy case experience and postgraduate year.

This study was to determine face and construct validity of a new virtual reality-based shoulder arthroscopy simulator which uses passive haptic feedback.

Safe and effective arthroscopic surgery requires ambidextrous motor skills. The current study examined dominant versus non-dominant hand performance on a virtual reality serious game in a group of expert arthroscopic surgeons (n=15) compared to a group of orthopedic surgery residents (n=10).

Orthopedic education continues to move towards evidence-based curriculum in order to comply with new residency accreditation mandates. There are currently three high fidelity arthroscopic virtual reality (VR) simulators available, each with multiple instructional modules and simulated arthroscopic procedures. The aim of the current study is to assess face validity, defined as the degree to which a procedure appears effective in terms of its stated aims, of three available VR simulators.

With the move to competency-based models of surgical training, a number of assessment methods have been developed. Of these, global rating scales have emerged as popular tools, and several are specific to the assessment of arthroscopic skills. Our aim was to determine which one of a group of commonly used global rating scales demonstrated superiority in the assessment of simulated arthroscopic skills.

Simulator training in orthopaedics is still in its infancy. The aim of this study is to determine face and construct validity of a new virtual reality simulator (VirtaMed ArthroS™) for diagnostic and therapeutic knee arthroscopy by analysis of simulator metrics of participants with varying arthroscopy experience.

As a new method of training on transurethral prostatectomy skills, training of TURP using a virtual simulator can help urologists improve their surgical skills and safety. Therefore, the application of the TURPSim™ system in education and training of urologic surgery is warranted.

Virtual reality (VR) surgical simulators provide repetitive practice and performance feedback without requiring supervision in a safe environment. Simulators have the potential to shorten the learning curve for complex surgical procedures, create skills which transfer to the operating room and therefore decrease the incidence of future complications. Experts resected a significantly greater percentage of prostate per minute [...] and had significantly less active diathermy time without tissue contact [...] than novices.

Significant differences between experts and novices in both performance and visual control strategy were observed. The study of visual control strategies may be a useful adjunct, alongside measurements of motor performance, providing a novel method of assessing the construct validity of surgical simulators.

Surgical simulators afford trainees the chance to practice skills in a safe environment and without the need for supervision. Although they have been proposed to shorten the learning curve for complex surgical skills, there is concern that they do not prepare trainees for the demanding conditions of the operating room. Research in skill learning (including surgical skills) has shown that experts and novices can be distinguished by differences in their visual control strategies, with experts using fewer fixations of a longer duration. The aim of this study was to assess the learning benefits of a TURP simulator by examining, not only changes in novice performance, but also changes in their visual control.

After the introduction of simulators in urology, education in urology has evolved significantly. Specially in endourology, development of Transurethral Resection of Prostate (TURP) skills are shifted from “direct on patient” to simulator based learning. we evaluated the development of TURP procedure skills based on virtual reality simulator (VirtaMed | UroSim™) and assessment of skills based on Global Rating Scale (GRS) evaluation system.

The objective of this cross-sectional study was to evaluate the self-reported effectiveness and acceptability of the PelvicSim™ (VirtaMed), a highfidelity mobile simulator, to train clinicians in intrauterine device (IUD) insertion.

Minimally invasive surgery is a major pillar of gynecological surgery. However, there are very few training opportunities outside the operation theater (OR) due to the cost and equipment requirements of organ simulators, virtual reality trainers (VRT) are promising tools to fill this gap.

Hysteroscopy is performed often and in many indications but is challenging to learn. Hands-on training in live patients faces ethical, legal, and economic obstacles. Virtual reality simulation may hold promise as a hysteroscopy training tool. No validated curriculum specific in hysteroscopy exists. The aim of this study was to develop a hysteroscopy curriculum, using the Delphi method to identify skill requirements.

The primary objective of our study was to test the construct validity of the HystSim hysteroscopic simulator to determine whether simulation training can improve the acquisition of hysteroscopic skills regardless of the previous levels of experience of the participants. The secondary objective was to analyze the performance of a selected task, using specially designed scoring charts to help reduce the learning curve for both novices and experienced surgeons.
