Validation of a novel assessment tool identifying proficiency in Transurethral Bladder Tumour Resection: The OSATURBS assessment tool

Current Standards for Training in Robot-assisted Surgery and Endourology: A Systematic Review

BACKGROUND AND OBJECTIVE

Different training programs have been developed to improve trainee outcomes in urology. However, evidence on the optimal training methodology is sparse. Our aim was to provide a comprehensive description of the training programs available for urological robotic surgery and endourology, assess their validity, and highlight the fundamental elements of future training pathways.

METHODS

We systematically reviewed the literature using PubMed/Medline, Embase, and Web of Science databases. The validity of each training model was assessed. The methodological quality of studies on metrics and curricula was graded using the MERSQI scale. The level of evidence (LoE) and level of recommendation for surgical curricula were awarded using the educational Oxford Centre for Evidence-Based Medicine classification.

KEY FINDINGS AND LIMITATIONS

A total of 75 studies were identified. Many simulators have been developed to aid trainees in mastering skills required for both robotic and endourology procedures, but only four demonstrated predictive validity. For assessment of trainee proficiency, we identified 18 in robotics training and six in endourology training; however, the majority are Likert-type scales. Although proficiency-based progression (PBP) curricula demonstrated superior outcomes to traditional training in preclinical settings, only four of six (67%) in robotics and three of nine (33%) in endourology are PBP-based. Among these, the Fundamentals of Robotic Surgery and the SIMULATE curricula have the highest LoE (level 1b). The lack of a quantitative synthesis is the main limitation of our study.

CONCLUSIONS AND CLINICAL IMPLICATIONS

Training curricula that integrate simulators and PBP methodology have been introduced to standardize trainee outcomes in robotics and endourology. However, evidence regarding their educational impact remains restricted to preclinical studies. Efforts should be made to expand these training programs to different surgical procedures and assess their clinical impact.

PATIENT SUMMARY

Simulation-based training and programs in which progression is based on proficiency represent the new standard of quality for achieving surgical proficiency in urology. Studies have demonstrated the educational impact of these approaches. However, there are still no standardized training pathways for several urology procedures.

Laypersons versus experienced surgeons in assessing simulated robot-assisted radical prostatectomy

BACKGROUND

Feedback is important for surgical trainees but it can be biased and time-consuming. We examined crowd-sourced assessment as an alternative to experienced surgeons' assessment of robot-assisted radical prostatectomy (RARP).

METHODS

We used video recordings (n = 45) of three RARP modules on the RobotiX, Simbionix simulator from a previous study in a blinded comparative assessment study. A group of crowd workers (CWs) and two experienced RARP surgeons (ESs) evaluated all videos with the modified Global Evaluative Assessment of Robotic Surgery (mGEARS).

RESULTS

One hundred forty-nine CWs performed 1490 video ratings. Internal consistency reliability was high (0.94). Inter-rater reliability and test-retest reliability were low for CWs (0.29 and 0.39) and moderate for ESs (0.61 and 0.68). In an Analysis of Variance (ANOVA) test, CWs could not discriminate between the skill level of the surgeons (p = 0.03-0.89), whereas ES could (p = 0.034).

CONCLUSION

We found very low agreement between the assessments of CWs and ESs when they assessed robot-assisted radical prostatectomies. As opposed to ESs, CWs could not discriminate between surgical experience using the mGEARS ratings or when asked if they wanted the surgeons to perform their robotic surgery.

Surgical experience is predictive for bladder tumour resection quality

OBJECTIVES

To assess the resection quality of transurethral bladder tumour resection (TURBT) and the association to surgeon experience depending on the presence of detrusor muscle.

METHODS

A retrospective study on 640 TURBT procedures performed at Zealand University Hospital, Denmark, from 1 January 2015 - 31 December 2016. Data included patient characteristics, procedure type, surgeon category, supervisor presence, surgical report data, pathological data, complications data and recurrence data. Analysis was performed using simple and multiple logistic regression on the association between surgeon experience and the presence of detrusor muscle in resected tissue from TURBT.

RESULTS

Supervised junior residents had significant lower detrusor muscle presence (73%) compared with consultants (83%) (OR = 0.4, 95% CI = 0.21-0.83). Limitations were the retrospective design and the diversity of included TURBT.

CONCLUSIONS

It was found that surgical experience predicts detrusor muscle presence and supervised junior residents performing TURBT on patients resulted in less detrusor muscle than consultants.
