Ulcerative Colitis Endoscopic Index of Severity (UCEIS) Score

Evaluates the severity of UC symptoms based on vascular pattern, bleeding and erosions & ulcers.

Refer to the text below the score for more information on the three descriptors used and the result interpretation.


The Ulcerative Colitis Endoscopic Index of Severity (UCEIS) helps clinicians with the endoscopic assessment of UC disease activity.

Compared to other scores (such as the Mayo or the Baron Score) is the most validated in several research studies and has consistently shown the best correlation with clinical symptoms.


The three descriptors of the model in combination account for 88% of variance between observers and 96% of the scale of the full range of severity.

UCEIS Score Explained

The Ulcerative Colitis Endoscopic Index of Severity (UCEIS) is used in the endoscopic assessment of disease activity in UC and compared to other scores (such as the Mayo or the Baron Score) is the most validated in several research studies and has consistently shown the best correlation with clinical symptoms.

The table below describes each of the three items and the interpretation of their answer choices:

UCEIS items Answer Choices
Vascular pattern Normal (1)
Normal vascular pattern with arborisation of capillaries clearly defined, or with blurring or patchy loss of capillary margins
Patchy obliteration (2)
Patchy obliteration of vascular pattern
Obliterated (3)
Complete obliteration of vascular pattern
Bleeding None (1)
No visible blood
Mucosal (2)
Some spots or streaks of coagulated blood on the surface of the mucosa ahead of the scope, which can be washed away
Luminal mild (3)
Some free liquid blood in the lumen
Luminal moderate or severe (4)
Frank blood in the lumen ahead of endoscope or visible oozing from mucosa after washing intra-luminal blood, or visible oozing from a haemorrhagic mucosa
Erosions & Ulcers None (1)
Normal mucosa, no visible erosions or ulcers
Erosions (2)
Tiny (<5mm) defects in the mucosa, of a white or yellow colour with a flat edge
Superficial ulcer (3)
Larger (>5mm) defects in the mucosa, which are discrete fibrin-covered ulcers when compared to erosions, but remain superficial
Deep ulcer (4)
Deeper excavated defects in the mucosa, with a slightly raised edge

The UCEIS score has so far shown good reliability (intra & inter-investigator performance) and may help with UC diagnosis, clinical trial and/or treatment decision making.

UCEIS Score Interpretation
0 - 1 Remission
2 - 4 Mild
5 - 6 Moderate
7 - 8 Severe

In the original study, Travis et al. observed UC symptoms and clinical signs agreement between experienced investigators and tested kappa statistics, inter-and intra-observer variability for each descriptor (0.34-0.65 and 0.30-0.45 within and between observers for 10 descriptors), finally using general linear mixed regression modelling.

The developed model retained the three descriptors: vascular pattern, bleeding and erosions & ulcers. The three terms in combination account for 88% of variance between observers and 96% of the scale of the full range of severity.

One of the limitations of the score is reported to be the unclear differentiation between erosion and superficial ulceration.

Several studies have found that the UCEIS outperformed the other readily available UC evaluation tool, the Mayo Score Disease Activity Index.
