Introduction Real-time assessment of operator performance during procedural simulation is a common practice that requires undivided attention by 1 or more reviewers, potentially over many repetitions of the same case. Objective To determine whether reviewers display better interrater agreement of procedural competency when observing recorded, rather than live, performance; and to develop an assessment tool for pediatric rapid sequence intubation (pRSI). Methods A framework of a previously established Objective Structured Assessment of Technical Skills (OSATS) tool was modified for pRSI. Emergency medicine residents (postgraduate year 1–4) were prospectively enrolled in a pRSI simulation scenario and evaluated by 2 live raters using the modified tool. Sessions were videotaped and reviewed by the same raters at least 4 months later. Raters were blinded to their initial rating. Interrater agreement was determined by using the Krippendorff generalized concordance method. Results Overall interrater agreement for live review was 0.75 (95% confidence interval [CI], 0.72–0.78) and for video was 0.79 (95% CI, 0.73–0.82). Live review was significantly superior to video review in only 1 of the OSATS domains (Preparation) and was equivalent in the other domains. Intrarater agreement between the live and video evaluation was very good, greater than 0.75 for all raters, with a mean of 0.81 (95% CI, 0.76–0.85). Conclusion The modified OSATS assessment tool demonstrated some evidence of validity in discriminating among levels of resident experience and high interreviewer reliability. With this tool, intrareviewer reliability was high between live and 4-months' delayed video review of the simulated procedure, which supports feasibility of delayed video review in resident assessment.

“…This system needs an instructed examiner during the evaluation procedure, which could be affected by bias due to the nonblinded process. Video assessment methods using GRS such as the Operative Component Rating Scale (OCRS) (17) provide a more objective blinded rating process with the same scoring criteria as live rating systems (8).…”

Minimally invasive surgery is a highly demanding surgical approach regarding technical requirements for the surgeon, who must be trained in order to perform a safe surgical intervention. Traditional surgical education in minimally invasive surgery is commonly based on subjective criteria to quantify and evaluate surgical abilities, which could be potentially unsafe for the patient. Authors, surgeons and associations are increasingly demanding the development of more objective assessment tools that can accredit surgeons as technically competent. This paper describes the state of the art in objective assessment methods of surgical skills. It gives an overview on assessment systems based on structured checklists and rating scales, surgical simulators, and instrument motion analysis. As a future work, an objective and automatic assessment method of surgical skills should be standardized as a means towards proficiency-based curricula for training in laparoscopic surgery and its certification.

“…Evaluation was often based on surgical outcomes and the subjective assessment of the attending physician. In recent years, a growing body of research has been aimed at developing a different approach to surgical education, one that uses various simulation models to objectively assess surgical skills [1,2,5,6,8,9,12,18].…”

Background Previously validated knee arthroscopy evaluation tools have used human cadaveric knees. This is unsustainable because of the cost and scarcity of these specimens. Porcine (pig) knees are anatomically similar, affordable, and easily obtainable; however, whether porcine knees represent a suitable alternative to human specimens has not been evaluated. Questions/purposes The purpose of this study was to determine whether porcine knees are similar to human cadaveric knees for the assessment of knee arthroscopy skills by evaluating (1) the validity of the porcine model (whether trainees of the same level of ability scored similarly when using the two models) and (2) the reliability of the porcine model (whether surgeons with experience achieved higher scores than surgeons with less experience in the porcine model). Methods Eleven orthopaedic surgery residents (five junior residents and six senior residents), one orthopaedic sports medicine fellow, and three attending orthopaedic surgeons were enrolled. Participants were provided instructions for a proper arthroscopic examination of the knee and asked to identify, and then probe, the listed anatomic structures on both the human and porcine knee specimens. Each participant was asked to demonstrate the following skills: joint manipulation, instrument control and triangulation, fluid management, maintenance of field of view, economy of movement, and efficiency. The Objective Assessment of Arthroscopic Skills (OAAS) and checklist for diagnostic arthroscopy of the knee were used for skills assessment by one observer. Internal consistency, a measure of how well the assessment tool measures the skills being studied, was determined by Cronbach's a and group differences investigated by paired t-test and Wilcoxon signed-rank tests where appropriate. Based on a sample size calculation, a total of 37 subjects would be required for the full-scale research study to achieve a power of 0.80, with a set at 0.05, to detect a difference in OAAS score of 4.73 (25%). This value is outside of the 95% confidence intervals for the human knee. Results We found the porcine model to have a high level of face validity. There was no difference with the numbers available in total OAAS scores (mean ± SD; 95% confidence interval [CI]) within subjects between the human (18.93 ± 7.54; 14.76-23.11) and porcine (17.87 ± 6.36; 14.34-21.39) knees (p = 0.433).

Toward reliable operative assessment: the reliability and feasibility of videotaped assessment of laparoscopic technical skills

Abstract: The use of videotapes of operations enabled multiple raters to assess a performance reliably and shortened assessment times by 80%. This assessment technique shows potential as a means of evaluating the performance of advanced laparoscopic procedures by surgical trainees.
