Developing an instrument to assess the endoscopic severity of ulcerative colitis: the Ulcerative Colitis Endoscopic Index of Severity (UCEIS)
Simon Travis,Dan Schnell,Piotr Krzeski,Maria T. Abreu,Douglas G. Altman,Jean-Frederic Colombel,Brian G. Feagan,Stephen B. Hanauer,Marc Lémann,Gary R. Lichtenstein,P. Marteau,Walter Reinisch,Bruce E. Sands,Bruce R. Yacyshyn,Christian A. Bernhardt,Jean-Yves Mary,William J. Sandborn +16 more
TL;DR: The Ulcerative Colitis Endoscopic Index of Severity accurately predicts overall assessment of endoscopic severity of UC and needs further testing before it can be applied as an outcome measure in clinical trials or clinical practice.
Journal ArticleDOI
Reliability and Initial Validation of the Ulcerative Colitis Endoscopic Index of Severity
Simon Travis,Dan Schnell,Piotr Krzeski,Maria T. Abreu,Douglas G. Altman,Jean-Frederic Colombel,Brian G. Feagan,Stephen B. Hanauer,Gary R. Lichtenstein,Philippe Marteau,Walter Reinisch,Bruce E. Sands,Bruce R. Yacyshyn,Patrick Schnell,Christian A. Bernhardt,Jean Yves Mary,William J. Sandborn +16 more
TL;DR: The UCEIS and its components show satisfactory intrainvestigator and interinvestigator reliability and was unaffected by knowledge of clinical details when assessing the endoscopic severity of UC.
Journal ArticleDOI
The Impact of Clinical Information on the Assessment of Endoscopic Activity: Characteristics of the Ulcerative Colitis Endoscopic Index Of Severity [UCEIS]
Simon Travis,Dan Schnell,Brian G. Feagan,Maria T. Abreu,Douglas G. Altman,Stephen B. Hanauer,Piotr Krzeski,Gary R. Lichtenstein,Philippe Marteau,Jean Yves Mary,Walter Reinisch,Bruce E. Sands,Patrick Schnell,Bruce R. Yacyshyn,Jean-Frederic Colombel,Christian A. Bernhardt,William J. Sandborn +16 more
TL;DR: The UCEIS is minimally affected by knowledge of clinical details, strongly correlates with patient-reported symptoms, and is a suitable instrument for trials.
