Aims/Background Endoscopic scoring systems are recommended internationally for assessing disease activity, response to therapy and mucosal healing. However, their real-world application remains inconsistent. This study aimed to evaluate the impact of an educational intervention on endoscopic scoring documentation and identify factors influencing its use. Methods A retrospective observational study was conducted at four hospital sites in Greater Manchester, UK. Data from endoscopies performed on ulcerative colitis (UC) patients were compared before and after an educational intervention. Logistic regression was used to analyse factors affecting documentation rates. Results Endoscopic score documentation increased from 39% (pre-intervention) to 46% (post-intervention) (p = 0.162). Nurse endoscopists had the highest documentation rates (83%), while surgeons had the lowest (8%). Attendance at educational sessions significantly increased documentation rates (29% vs. 74-80%, p < 0.001). Conclusion Educational interventions modestly improved endoscopic scoring documentation. Further targeted training and standardised reporting templates are needed to enhance adherence and patient outcomes in UC management.
