Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
One of the primary challenges in implementing these scoring systems is inter-observer variability, as highlighted by significant discrepancies between scores assigned by local and central reviewers. However, the performance of these systems among experts has been shown to be excellent, suggesting that achieving consistent and accurate scoring requires a high level of exposure and proficiency.
Inconsistent scoring, especially among less experienced clinicians, poses a challenge to the reliability of these scoring systems.
The primary objective of this study is to evaluate the improvement of scoring accuracy after training with structured educational videos with a specific focus on the learning curve and the practical application of endoscopic scoring systems.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Endoscopic scoring systems are vital for the objective assessment of disease activity being used in both clinical trials and daily clinical practice. These standardized scoring systems are essential for diagnosing, evaluating endoscopic healing, monitoring treatment response, and predicting clinical outcomes.
The most widely adapted scoring systems in IBD include:
* The Simple Endoscopic Score for Crohn's Disease (SES-CD) evaluates four key parameters: ulcer size, ulcerated surface, affected surface area, and luminal narrowing. It offers a straightforward, clinically validated scoring system that strongly correlates with indices such as the Crohn's Disease Activity Index.
* The updated Rutgeerts Score provides accurate and clinically relevant assessments of postoperative recurrence in CD and facilitates the prediction of clinical and surgical outcomes for patients with an ileocolonic anastomosis.
* The Endoscopic Mayo Score is a component of the broader Mayo scoring system used to assess disease activity in UC. It evaluates the extent and severity of mucosal inflammation, correlating well with clinical outcomes, including treatment response.
* The Ulcerative Colitis Endoscopic Index of Severity (UCEIS) standardizes the evaluation of endoscopic severity in UC. It incorporates more detailed descriptors of mucosal appearance, including vascular pattern, bleeding, erosions, and ulcerations to describe overall disease severity (Neurath \& Travis, 2012).
* The Pouchitis Disease Activity Index (PDAI) assesses pouchitis severity using clinical symptoms, endoscopic findings, and histological features of the pouch. This quantitative tool helps to diagnose and monitor pouchitis. Endoscopic part of PDAI (ePDAI) consists of six features describing mucosal changes: oedema, granularity, friability, loss of vascular pattern, mucous exudate and ulceration.
* The Simplified Endoscopic Score for Pouchitis (SES-pouchitis), recently suggested as an alternative to the PDAI, adapts the SES-CD framework to focus on one single segment, namely the ileal pouch.
One of the primary challenges in implementing these scoring systems is inter-observer variability, as highlighted by significant discrepancies between scores assigned by local and central reviewers. However, the performance of these systems among experts has been shown to be excellent, suggesting that achieving consistent and accurate scoring requires a high level of exposure and proficiency.
Inconsistent scoring, especially among less experienced clinicians, poses a challenge to the reliability of these scoring systems. Daperno et al. demonstrated in their study that a structured educational training program significantly enhanced inter-observer agreement. The study, including 237 gastroenterologists with at least three years of post-certification experience, showed substantial improvements in scoring consistency across multiple IBD scoring systems (SES-CD, Mayo Endoscopic Subscore, and Rutgeerts Score) following the training. These findings emphasize the importance of comprehensive training to ensure reliable and consistent endoscopic evaluations. Intensive education programs are crucial for improving scoring accuracy, enabling effective disease monitoring and management in IBD.
New scoring systems for assessing disease activity are developing, however, they are relatively unknown among gastroenterologists and are not yet widely used in clinical practice.
In the CONCORDIA study, the investigators will evaluate gastroenterology fellows' familiarity with these new scoring systems and assess whether structured endoscopic video assisted training improves scoring accuracy.

RANDOMIZED
SEQUENTIAL
Following the first video assessment only participants in Group A will attend the structured training module.
During Time Period 2 (one month), all participants will score the same 15 + 15 videos. However, only participant in Group A will have access to the explanatory videos used in the online training module.
After the second video assessment participants in Group B will receive the structured training module.
During Time Period 3 (one months), participants in Group B will score the 15 + 15 videos again while having access to the explanatory videos used in the online training.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group A (Early training)
Following the first video assessment only participants in Group A will attend the structured training module.
During Time Period 2 (approximately one month), all participants will score the same 15 + 15 videos. However, only participant in Group A will have access to the explanatory videos used in the online training module.
Training
A structured teaching module for fellows in training will be prepared and conducted at three university centres, namely University Hospitals Leuven, Ljubljana University Medical Centre, and CHU de Bordeaux. The training module will include short endoscopic videos (different from the pre- and post-training set), which participants will score in real-time using a polling application. This will be followed by a step-by-step demonstration of each scoring principle with explanations of the reasoning behind specific scores. Each scoring system will be reviewed in a short training video that provides a structured demonstration, highlights common pitfalls, and showcases typical IBD-associated endoscopic features. After the video training, participants will have the opportunity to ask questions to the experts.
Group B (Late training)
After the second video assessment participants in Group B will receive the structured training module.
During Time Period 3 (approximately one month), participants in Group B will score the 15 + 15 videos again while having access to the explanatory videos used in the online training module.
