Measures Of Performance

Background. In this pilot study, we evaluated tip collisions against three commonly used measures of fibreoptic scope handling skills. Methods. Seventy-seven anaesthetists were recruited to perform a standardized task on an Oxford Box and a modified AirSim manikin. Collision count was correlated against time to scope placement, a global rating scale score, and up-to-date fibreoptic experience. Results. Strong and moderate correlations were found between collision count and task completion time for the Oxford Box (ρ = 0.730, P < 0.0001) and AirSim manikin (ρ = 0.405, P < 0.0001), respectively. Moderate correlation was found between collision count and global rating scale score for the Oxford Box (ρ = −0.545, P < 0.0001) and AirSim manikin (ρ = −0.500, P < 0.0001). Mild and moderate correlations were found between collision count and fibreoptic experience on the Oxford Box (ρ = −0.240, P = 0.041) and AirSim manikin (ρ = −0.423, P < 0.0001), respectively. Conclusions. This study infers that collision count may be used as a measure of fibreoptic scope handling skills in simulation training. Using this outcome in addition to other measures of performance may improve accuracy and precision of fibreoptic scope placement.

Background: Arthroscopic hip labral repair is a technically challenging and demanding surgical technique with a steep learning curve. Arthroscopic simulation allows trainees to develop these skills in a safe environment. Purpose: The purpose of this study was to evaluate the use of a combination of assessment ratings for the performance of arthroscopic hip labral repair on a dry model. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 47 participants including orthopaedic surgery residents (n = 37), sports medicine fellows (n = 5), and staff surgeons (n = 5) performed arthroscopic hip labral repair on a dry model. Prior arthroscopic experience was noted. Participants were evaluated by 2 orthopaedic surgeons using a task-specific checklist, the Arthroscopic Surgical Skill Evaluation Tool (ASSET), task completion time, and a final global rating scale. All procedures were video-recorded and scored by an orthopaedic fellow blinded to the level of training of each participant. Results: The internal consistency/reliability (Cronbach alpha) using the total ASSET score for the procedure was high (intraclass correlation coefficient > 0.9). One-way analysis of variance for the total ASSET score demonstrated a difference between participants based on the level of training ( F3,43 = 27.8, P < .001). A good correlation was seen between the ASSET score and previous exposure to arthroscopic procedures ( r = 0.52-0.73, P < .001). The interrater reliability for the ASSET score was excellent (>0.9). Conclusion: The results of this study demonstrate that the use of dry models to assess the performance of arthroscopic hip labral repair by trainees is both valid and reliable. Further research will be required to demonstrate a correlation with performance on cadaveric specimens or in the operating room.

Abstract Background Medical simulation trainings lead to an improvement in patient care by increasing technical and non-technical skills, procedural confidence and medical knowledge. For structured simulation-based trainings, objective assessment tools are needed to evaluate the performance during simulation and the learning progress. In surgical education, objective structured assessment of technical skills (OSATS) are widely used and validated. However, in emergency medicine and anesthesia there is a lack of validated assessment tools for technical skills. Thus, the aim of the present study was to develop and validate a novel Global Rating Scale (GRS) for emergency medical simulation trainings. Methods Following the development of the GRS, 12 teams of different experience in emergency medicine (4th year medical students, paramedics, emergency physicians) were involved in a pre-hospital emergency medicine simulation scenario and assessed by four independent raters. Subsequently, interrater reliability and construct validity of the GRS were analyzed. Moreover, the results of the GRS were cross-checked with a task specific check list. Data are presented as median (minimum; maximum). Results The GRS consists of ten items each scored on a 5-point Likert scale yielding a maximum of 50 points. The median score achieved by novice teams was 22.75 points (17;30), while experts scored 39.00 points (32;47). The GRS overall scores significantly discriminated between student-guided teams and expert teams of emergency physicians (p = 0.005). Interrater reliability for the GRS was high with a Kendall’s coefficient of concordance W ranging from 0.64 to 0.90 in 9 of 10 items and 0.88 in the overall score. Conclusion The GRS represents a promising novel tool to objectively assess technical skills in simulation training with high construct validity and interrater reliability in this pilot study.

Abstract Background The ongoing COVID-19 pandemic has disrupted the surgical training of residents. There is a real concern that trainees will not be able to meet their training requirements. Low-fidelity surgical simulation appears to be an alternative for surgical training. The educational benefits of repeating ossiculoplasty simulations under a microscope have never been evaluated. With this study we aimed to evaluate the differences in performance scores and on a global rating scale before and after training on an ossiculoplasty simulator. Methods In this quasi-experimental, prospective, single-centre, before-after study with blinded rater evaluation, residents performed five microscopic ossiculoplasty tasks with a difficulty gradient (sliding beads onto rods, the insertion of a partial prosthesis, the insertion of a total prosthesis, and the insertion of a stapedotomy piston under microscopic or endoscopic surgery) before and after training on the same simulator. Performance scores were defined for each task, and total performance scores (score/min) were calculated. All data were collected prospectively. Results Six out of seven intermediate residents and 8/9 novices strongly agreed that the simulator was an effective training device and should be included in the ENT residency program. The mean effect of training was a significant increase in the total performance score (+ 0.52 points/min, [95 % CI, 0.40–0.64], p < 0.001), without a significant difference between novice and intermediate residents. Conclusions This preliminary study shows that techniques for middle-ear surgery can be acquired using a simulator, avoiding any risk for patients, even under lockdown measures.

Cortical Mastoidectomy

Abstract Objective This study developed an assessment tool that was based on the objective structured assessment for technical skills principles, to be used for evaluation of surgical skills in cortical mastoidectomy. The objective structured assessment of technical skill is a well-established tool for evaluation of surgical ability. This study also aimed to identify the best material and printing method to make a three-dimensional printed temporal bone model. Methods Twenty-four otolaryngologists in training were asked to perform a cortical mastoidectomy on a three-dimensional printed temporal bone (selective laser sintering resin). They were scored according to the objective structured assessment of technical skill in temporal bone dissection tool developed in this study and an already validated global rating scale. Results Two external assessors scored the candidates, and it was concluded that the objective structured assessment of technical skill in temporal bone dissection tool demonstrated some main aspects of validity and reliability that can be used in training and performance evaluation of technical skills in mastoid surgery. Conclusion Apart from validating the new tool for temporal bone dissection training, the study showed that evolving three-dimensional printing technologies is of high value in simulation training with several advantages over traditional teaching methods.

Suturing Skills

Abstract Aim To evaluate the use of telementoring in acquisition of basic suturing skills in medical students. Method This was a single blinded two- armed randomised control trial. Medical students undergoing clinical rotations in their penultimate and final years were invited to participate in this study. Informed consent was obtained. The control group underwent conventional suturing training, with the interventional group undergoing the tutorial in a remote learning setting via live streaming. Pre- and post-test assessment was carried out using validated Global Rating Scale tool. Results Eleven students were enrolled in this study. Participants were comparable at baseline (p=.18) and following the tutorial (p=.29). Participants improved to a statistically significant degree in both the virtual group (p=.02) and the in-person group (p=.001). Conclusions Telementoring is an effective tool in the provision of teaching basic suturing skills in medical students. Research on its use in more complex practical skills is warranted.

Microlaryngeal Surgery

Objectives. The simulation of microlaryngeal skills is rarely seen in surgical training, but it is particularly important in phonomicrosurgery. This study described and validated the laryngeal surgical simulator through surgical training.Methods. A simple and low-cost simulator was developed for the fixation of the suspension laryngoscope and porcine larynges. Twenty participants with work skills and experience did preparation before training, and performed suture and carbon dioxide (CO2) laser cordectomy for simulator evaluation. The results were proposed by the aspects of time taken for each procedure, the global rating scale, a procedure-specific assessment, and a post-simulation questionnaire.Results. All participants completed the preparation within 9 minutes and reached the conclusion that the microlaryngeal surgical simulator was helpful in improving their surgical skills. The performance of experts was superior to that of novices in both suture and CO2 laser cordectomy.Conclusion. This simulator could be easily assembled and was successfully validated by microlaryngeal surgical training both subjectively and objectively. It may be helpful to clinicians in microlaryngeal skills.
