“…2 a Correlation between the number of attempts needed to reach the ventricle (In = catheter that reached and stayed inside the ventricle; Out = catheter outside the ventricle) and number of EVDs placed during the entire career of a resident/neurosurgeon; having placed more EVDs overall does not correlate with fewer attempts when positioning a virtual EVD at the simulator. b Correlation between the number of attempts needed to reach the ventricle and number of EVDs placed during the previous year of practice of a resident/neurosurgeon; having placed more EVDs in the last year of time correlates with fewer attempts when positioning a virtual EVD at the simulator results concurred with ours as they too demonstrated how only a precise and continuous training scheme would permit the finest acquisition of all quintessential neurosurgical skills [23]. In line with our findings, the mixed-reality ventriculostomy simulator described by Hooten et al demonstrated a strong relationship between the scores and the participant's level of training [24].…”

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.

“…Additionally, a number of studies have reported the benefits of spacing while learning surgical skills (Moulton et al, 2006; Verdaasdonk et al, 2007; Gallagher et al, 2012; De Win et al, 2013; Spruit et al, 2014; Kang et al, 2015). Some of these studies provide information on effect sizes.…”

Recent accounts of the spacing effect have proposed molecular explanations that explain spacing over short, but not long timescales. In the first half of this paper, we review research on the spacing effect that has employed spaces of 24 h or more across skill-related tasks, language-related tasks and generalization for adults and children. Throughout this review, we distinguish between learning and retention by defining learning (or acquisition) as performance at the end of training and retention as performance after a delay period. Using this distinction, we find age- and task-related differences in the manifestation of the spacing effect over long timescales. In the second half of this paper, we discuss a reconsolidation account of the spacing effect. In particular, we review the evidence that suggests the spacing of repetitions influences the subsequent consolidation and reconsolidation processes; we explain how a reconsolidation account may explain the findings for learning; the inverted-U curve for retention; and compare the reconsolidation account with previous consolidation accounts of the spacing effect.

“…Results indicated that Groups one and two displayed a similar increase in post testing performance compared to baseline. Daily training has been suggested to be the most appropriate for the dV-Trainer [22]. Kang et al compared three training schedules: 1 h daily for four consecutive days, 1 h weekly for four consecutive weeks, and four consecutive hours in 1 day.…”

Current state of virtual reality simulation in robotic surgery training: a review

There are many benefits to utilizing VR simulation for robotic skills acquisition. Four commercially available simulators have been demonstrated to be capable of assessing robotic skill. Three of the four simulators demonstrate the ability of a VR training curriculum to improve basic robotic skills, with proficiency-based training being the most effective training style. The skills obtained on a VR training curriculum are comparable with those obtained on dry laboratory simulation. The future of VR simulation includes utilization in assessment for re-credentialing purposes, advanced procedural-based training, and as a warm-up tool prior to surgery.
