“…SPARC is being increasingly used to measure skilled or smooth motion, including in the previously mentioned FEVS studies [Duran et al (2015), O'Malley et al ( 2019), Belvroy et al (2020)], in which it consistently demonstrates strong correlations to skill between experts and novices. In this study, we systematically compare the efficacy of both SPARC and LDLJ for quantifying cannulation skill-another clinical skill that requires smooth motion.…”

“…Further, simulators often enable self-paced learning via metrics that track the performance of trainees over time. In recent years, simulator training has demonstrated positive results in arthroscopy, laparoscopy, and endovascular surgery [Rosen (2008), Hafford et al (2013), Duran et al (2015), Goyal et al (2016)]. Many simulators used in these studies provided skill assessment objectively (i.e., through sensor-based metrics) and not the "subjective" assessment of a trainer.…”

Motion Smoothness Metrics for Cannulation Skill Assessment: What Factors Matter?

Medical training simulators have the potential to provide remote and automated assessment of skill vital for medical training. Consequently, there is a need to develop “smart” training devices with robust metrics that can quantify clinical skills for effective training and self-assessment. Recently, metrics that quantify motion smoothness such as log dimensionless jerk (LDLJ) and spectral arc length (SPARC) are increasingly being applied in medical simulators. However, two key questions remain about the efficacy of such metrics: how do these metrics relate to clinical skill, and how to best compute these metrics from sensor data and relate them with similar metrics? This study addresses these questions in the context of hemodialysis cannulation by enrolling 52 clinicians who performed cannulation in a simulated arteriovenous (AV) fistula. For clinical skill, results demonstrate that the objective outcome metric flash ratio (FR), developed to measure the quality of task completion, outperformed traditional skill indicator metrics (years of experience and global rating sheet scores). For computing motion smoothness metrics for skill assessment, we observed that the lowest amount of smoothing could result in unreliable metrics. Furthermore, the relative efficacy of motion smoothness metrics when compared with other process metrics in correlating with skill was similar for FR, the most accurate measure of skill. These results provide guidance for the computation and use of motion-based metrics for clinical skill assessment, including utilizing objective outcome metrics as ideal measures for quantifying skill.

“…although these do not represent real vascular structures, they are designed from the perspective of enhancing the training and assessment of endovascular surgeons by focusing on specific tasks. 46 Phantom models are primarily used for obtaining dexterity skills for catheter/guidewire manipulation and stent/baloon deployment, with the advantage over VR simulators in the sense that the surgeon operates on real materials under actual surgical conditions and is placed within a real fluoroscopy suite. The major disadvantage of training using phantom models, is that the trainee is still exposed to radiation within the training environment and that such facilities are rare and costly to maintain.…”

Minimally invasive endovascular interventions have evolved rapidly over the past decade, facilitated by breakthroughs in medical imaging and sensing, instrumentation and most recently robotics. Catheter-based operations are potentially safer and applicable to a wider patient population due to the reduced comorbidity. As a result endovascular surgery has become the preferred treatment option for conditions previously treated with open surgery and as such the number of patients undergoing endovascular interventions is increasing every year. This fact coupled with a proclivity for reduced working hours results in a requirement for efficient training and assessment of new surgeons, that deviates from the “see one, do one, teach one” model introduced by William Halsted, so that trainees obtain operational expertise in a shorter period. Developing more objective assessment tools based on quantitative metrics is now a recognized need in interventional training and this manuscript reports the current literature for endovascular skills assessment and the associated emerging technologies. A systematic search was performed on PubMed (MEDLINE), Google Scholar, IEEXplore and known journals using the keywords, “endovascular surgery”, “surgical skills”, “endovascular skills”, “surgical training endovascular” and “catheter skills”. Focusing explicitly on endovascular surgical skills, we group related works into three categories based on the metrics used; structured scales and checklists, simulation-based and motion-based metrics. This review highlights the key findings in each category and also provides suggestions for new research opportunities towards fully objective and automated surgical assessment solutions.

The model for Fundamentals of Endovascular Surgery (FEVS) successfully defines the competent endovascular surgeon

Abstract: The Fundamentals of Endovascular Surgery model successfully differentiates competent and noncompetent performance of fundamental endovascular skills based on a series of objective performance measures. This model could serve as a platform for skills testing for all trainees.
