Impact of Simulation Training on Diagnostic Arthroscopy Performance: A Randomized Controlled Trial.

ABSTRACT: Purpose:To determine the impact of training on a virtual reality arthroscopy simulator on both simulator and cadaveric performance in novice trainees. Methods:A randomized controlled trial of 28 participants without prior arthroscopic experience was conducted. All participants received a demonstration of how to use the ArthroVision Virtual Reality Simulator and were then randomized to receive either no training (control group, n = 14) or a fixed protocol of simulation training (n = 14). All participants took a pretest on the simulator, completing 9 tasks ranging from camera-steadying tasks to probing structures. The training group then trained on the simulator (1 time per week for 3 weeks). At week 4, all participants completed a 2-part post-test, including (1) performing all tasks on the simulator and (2) performing a diagnostic arthroscopy on a cadaveric knee and shoulder. An independent, blinded observer assessed the performance on diagnostic arthroscopy using the Arthroscopic Surgical Skill Evaluation Tool scale. To compare differences between non-normally distributed groups, the Mann-Whitney U test was used. An independent-samples t test was used for normally distributed groups. The Friedman test with pair-wise comparisons using Bonferroni correction was used to compare scores within groups at multiple time points. Bonferroni adjustment was applied as a multiplier to the P value; thus, the ? level remained consistent. Significance was defined as P < .05. Results:In both groups, all tasks except task 5 (in which completion time was relatively fixed) showed a significant degree of correlation between task completion time and other task-specific metrics. A significant difference between the trained and control groups was found for post-test task completion time scores for all tasks. Qualitative analysis of box plots showed minimal change after 3 trials for most tasks in the training group. There was no statistical correlation between the performance on diagnostic arthroscopy on either the knee or shoulder and simulation training, with no difference in Arthroscopic Surgical Skill Evaluation Tool scores in the training group compared with controls. Conclusions:Our study suggests that an early ceiling effect is shown on the evaluated arthroscopic simulator model and that additional training past the point of proficiency on modern arthroscopic simulator models does not provide additional transferable benefits on a cadaveric model. Level of Evidence:Level I, randomized controlled trial.

Project description:Purpose:To prospectively evaluate the transferability of skills acquired on a low-cost, at-home, nonanatomic triangulation simulation system to cadaveric models. Methods:We randomized 28 medical students into either a simulator-training group (n = 14) or group with no training (control, n = 14). All subjects were pretested using a standardized checklist of arthroscopic skills on cadaveric knees and shoulders. Training-group subjects practiced on the triangulation simulator for 90 minutes per week for 4 consecutive weeks. Control subjects received no training. All subjects completed a post-test checklist of arthroscopic skills on cadaveric knees and shoulders, as well as 4 training tasks on the simulator. A blinded orthopaedic surgeon evaluated the arthroscopic videos using the Arthroscopic Surgical Skill Evaluation Tool (ASSET) score. Results:Training-group knee and shoulder ASSET scores increased from 12.2 ± 1.85 to 14.6 ± 2.76 (P = .02) and from 14.6 ± 3.5 to 17.9 ± 4.5 (P = .29), respectively. In the control group, knee and shoulder ASSET scores increased from 14.3 ± 3.12 to 14.25 ± 4.67 (P = .99) and from 14.2 ± 2.7 to 17.07 ± 6.7 (P = .58), respectively. There were no significant differences in the mean post-test ASSET scores between the training group and control group for either knee or shoulder arthroscopy. The post-test ASSET safety subscore during knee arthroscopy was significantly higher in the training group (P = .03). The training group was able to complete significantly more simulator tasks compared with controls (P = .003) at post-testing. A significant positive correlation was found between knee arthroscopy performance and the number of tasks completed during simulation post-testing (P = .043). There was no significant correlation between shoulder arthroscopy performance and simulation performance (P = .532). Conclusions:Basic triangulation skills may be acquired by training on a low-cost, at-home, nonanatomic triangulation simulation system, although the degree of transferability and universal joint applicability, as well as the existence of an early ceiling effect in skill development, could not be shown. Level of Evidence:Level II, randomized controlled trial.

Project description:PurposeLimited data exist on the actual transfer of skills learned using a virtual reality (VR) simulator for arthroscopy training because studies mainly focused on VR performance improvement and not on transfer to real word (transfer validity). The purpose of this single-blinded, controlled trial was to objectively investigate transfer validity in the context of initial knee arthroscopy training.MethodsFor this study, 36 junior resident orthopaedic surgeons (postgraduate year one and year two) without prior experience in arthroscopic surgery were enrolled to receive standard knee arthroscopy surgery training (NON-VR group) or standard training plus training on a hybrid virtual reality knee arthroscopy simulator (1 h/month) (VR group). At inclusion, all participants completed a questionnaire on their current arthroscopic technical skills. After 6 months of training, both groups performed three exercises that were evaluated independently by two blinded trainers: i) arthroscopic partial meniscectomy on a bench-top knee simulator; ii) supervised diagnostic knee arthroscopy on a cadaveric knee; and iii) supervised knee partial meniscectomy on a cadaveric knee. Training level was determined with the Arthroscopic Surgical Skill Evaluation Tool (ASSET) score.ResultsOverall, performance (ASSET scores) was better in the VR group than NON-VR group (difference in the global scores: p < 0.001, in bench-top meniscectomy scores: p = 0.03, in diagnostic knee arthroscopy on a cadaveric knee scores: p = 0.04, and in partial meniscectomy on a cadaveric knee scores: p = 0.02). Subgroup analysis by postgraduate year showed that the year-one NON-VR subgroup performed worse than the other subgroups, regardless of the exercise.ConclusionThis study showed the transferability of the technical skills acquired by novice residents on a hybrid virtual reality simulator to the bench-top and cadaveric models. Surgical skill acquired with a VR arthroscopy surgical simulator might safely improve arthroscopy competences in the operating room, also helping to standardise resident training and follow their progress.Level of evidence: 2

Project description:Most patients undergoing outpatient surgeries have the unpleasant experience of high level pain after surgery. Compared with open surgeries, arthroscopic procedures are less painful; however, inadequate pain management could be associated with significant concerns. Opioids alone or in combination with local anesthetics are frequently used for diminishing postoperative pain using intravenous or epidural infusion pumps. Despite morphine various disadvantages, it is commonly used for controlling pain after surgery.The aim of this study was to compare intravenous paracetamol and patient-controlled analgesia (PCA) with morphine for the pain management following diagnostic knee arthroscopy in trauma patients.Sixty trauma patients who were scheduled to undergo knee arthroscopy were randomly divided into two groups. Patients immediately received intravenous infusion of 1 g paracetamol within 15 minutes after surgery and every 6 hours to 24 hours in the paracetamol group. The patient-controlled analgesia group received morphine through PCA infusion pump at 2 mL/h base rate and 1mL bolus every 15 minutes. Pain level, nausea and vomiting, and sedation were measured and recorded during entering the recovery, 15 and 30 minutes after entering the recovery, 2, 6, and 24 hours after starting morphine pump infusion in the morphine and paracetamol in the paracetamol groups.There was no significant difference regarding the pain level at different times after entering the recovery between the two groups. No one from the paracetamol group developed drug complications. However, 22.3% in the PCA morphine suffered from postoperative nausea; there was a statistically significant difference regarding the sedation level, nausea, and vomiting at various times between the two groups.Intravenous administration of paracetamol immediately after knee arthroscopy improved postoperative pain, decreased analgesic administration, maintained stable hemodynamic parameters, had no complications related to opiates, no nausea and vomiting, and increased patient satisfaction and comfort in comparison to PCA with morphine.

Project description:BACKGROUND:Non-technical skills (NTS), such as communication and professionalism, contribute to the safe and effective completion of procedures. NTS training has previously been shown to improve surgical performance. Moreover, increases in NTS have been associated with improved clinical endoscopic performance. Despite this evidence, NTS training has not been tested as an intervention in endoscopy. OBJECTIVE:The aim of this study is to evaluate the effectiveness of a simulation-based training (SBT) curriculum of NTS on novice endoscopists' performance of clinical colonoscopy. METHODS:Novice endoscopists were randomized to 2 groups. The control group received 4 hours of interactive didactic sessions on colonoscopy theory and 6 hours of SBT. Hours 5 and 6 of the SBT were integrated scenarios, wherein participants interacted with a standardized patient and nurse, while performing a colonoscopy on the virtual reality (VR) simulator. The NTS (intervention) group received the same teaching sessions but the last hour was focused on NTS teaching. The NTS group also reviewed a checklist of tasks relevant to NTS concepts prior to each integrated scenario case and was provided with dedicated feedback on their NTS performance during the integrated scenario practice. All participants were assessed at baseline, immediately after training, and 4 to 6 weeks post-training. The primary outcome measure is colonoscopy-specific performance in the clinical setting. RESULTS:In total, 42 novice endoscopists completed the study. Data collection and analysis is ongoing. We anticipate completion of all assessments by August 2017. Data analysis, manuscript writing, and subsequent submission for publication is expected to be completed by December 2017. CONCLUSIONS:Results from this study may inform the implementation of NTS training into postgraduate gastrointestinal curricula. NTS curricula may improve attitudes towards patient safety and self-reflection among trainees. Moreover, enhanced NTS may lead to superior clinical performance and outcomes in colonoscopy.
