Background: Practice on Virtual Reality simulators (VRS) have been shown to improve surgical performance. However, VRS are expensive and usually housed in surgical skills centres that may be inaccessible at times convenient for surgical trainees to practice. Conversely, box trainers are inexpensive and can be used anywhere at anytime. This study assesses "take-home" Box Trainers (BT) as an alternative to VRS.Methods: After baseline assessments (two simulated laparoscopic cholecystectomies, one on a VRS and one on a BT) 25 surgical trainees were randomised to two groups. Trainees were asked to practice 3 basic laparoscopic tasks for 6 weeks (BT group using a "take-home" box trainer; VR group using VRS in clinical skills centres). After the practice period all performed two LC, one on a VRS and one on a BT; (i.e. post-training assessment). VRS provided metrics (total time (TT), number of movements (NOM) instrument tip path length (PL)) and expert video assessment of cholecystectomy in a BT (GOALS score) were recorded. Performance during pre-and post-training assessment was compared.Results: The BT group showed a significant improvement for all VRS metrics (p=0.008) and the efficiency category of GOALS score (p=0.03). Only TT improved in the VRS group and none of the GOALS categories demonstrated a statistically significant improvement after training.

“…These models have been created to improve the experience before medical students interact with human patients or volunteers. In this context, simulators are strongly supported by supervisors in terms of students' acquisition of both technical and non-technical skills [3]. Using simulators to train audiometry will better prepare students for future clinical practice.…”

Training outcomes for audiology students using virtual reality or traditional training methods

Due to limited space and resources, it can be difficult to train students on audiological procedures adequately. In the present study, we compared audiology training outcomes between a traditional approach and a recently developed immersive virtual reality (VR) approach in audiology students. Twenty-nine first-year audiology students participated in the study; 14 received traditional training (“TT group”), and 15 received the VR training (“VRT group”). Pre- and post-training evaluation included a 20-item test developed by an audiology educator. Post-training satisfaction and self-confidence were evaluated using Likert scales. Mean post-training test scores improved by 6.9±9.8 percentage points in the TT group and by 21.1±7.8 points in the VRT group; the improvement in scores was significant for both groups. After completing the traditional training, the TT group was subsequently trained with the VR system, after which mean scores further improved by 7.5 points; there was no significant difference in post-VR training scores between the TT and VRT groups. After training, the TT and VRT groups completed satisfaction and self-confidence questionnaires. Satisfaction and self-confidence ratings were significantly higher for the VR training group, compared to the traditional training group. Satisfaction ratings were “good” (4 on Likert scale) for 74% of the TT group and 100% of the VRT group. Self-confidence ratings were “good” for 71% of the TT group and 92% of the VRT group. These results suggest that a VR training approach may be an effective alternative or supplement to traditional training for audiology students.

“…In this regard, virtual reality simulatorswith haptic feedback technology-might be able to create a realistic and safe environment, where both residents and surgeons could train and practice, in order to perform this procedure better and more safely [4]. To date, it has not been clearly demonstrated if training with simulation determines a better neurosurgical performance; this is a very difficult question to answer, since many factors contribute to the final outcome [5].…”

Filling the gap between the OR and virtual simulation: a European study on a basic neurosurgical procedure

et al. 2018

Background Currently available simulators are supposed to allow young neurosurgeons to hone their technical skills in a safe environment, without causing any unnecessary harm to their patients caused by their inexperience. For this training method to be largely accepted in neurosurgery, it is necessary to prove simulation efficacy by means of large-scale clinical validation studies. Methods We correlated and analysed the performance at a simulator and the actual operative skills of different neurosurgeons (construct validity). We conducted a study involving 92 residents and attending neurosurgeons from different European Centres; each participant had to perform a virtual task, namely the placement of an external ventricular drain (EVD) at a neurosurgical simulator (ImmersiveTouch). The number of attempts needed to reach the ventricles and the accuracy in positioning the catheter were assessed. Results Data suggests a positive correlation between subjects who placed more EVDs in the previous year and those who get better scores at the simulator (p = .008) (fewer attempts and better surgical accuracy). The number of attempts to reach the ventricle was also analysed; senior residents needed fewer attempts (mean = 2.26; SD = 1.11) than junior residents (mean = 3.12; SD = 1.05) (p = .007) and staff neurosurgeons (mean = 2.89, SD = 1.23). Scoring results were compared by using the Fisher's test, for the analysis of the variances, and the Student's T test. Surprisingly, having a wider surgical experience overall does not correlate with the best performance at the simulator. Conclusion The performance of an EVD placement on a simulator correlates with the density of the neurosurgical experience for that specific task performed in the OR, suggesting that simulators are able to differentiate neurosurgeons according to their surgical ability. Namely this suggests that the simulation performance reflects the surgeons' consistency in placing EVDs in the last year.

Perceptions About the Present and Future of Surgical Simulation: A National Study of Mixed Qualitative and Quantitative Methodology

Abstract: The use of simulation for the acquirement of both technical and nontechnical skills is strongly supported while views on other applications (e.g., assessment) are conflicting. Further, the need for center accreditation and supervised, consultant-led teaching is highlighted.
