How to use

  1. At the most severely affected segment, select each of the three endoscopic descriptors.
  2. The total UCEIS (0–8) and activity band update instantly.
  3. A UCEIS of 0–1 indicates endoscopic remission.

Frequently asked questions

What is the UCEIS?

The Ulcerative Colitis Endoscopic Index of Severity scores three descriptors — vascular pattern, bleeding, and erosions/ulcers — for a total of 0–8 at the most severe segment.

What UCEIS defines remission?

A UCEIS of 0–1 corresponds to endoscopic remission; higher scores indicate increasing activity and predict worse outcomes.

UCEIS vs Mayo endoscopic subscore?

The UCEIS is more granular and has better inter-observer reliability than the single Mayo endoscopic subscore, especially for moderate disease.

Which bowel segment is scored?

The single most severely affected area visualised at endoscopy is used to assign each descriptor.
