uceis_score: Ulcerative Colitis Endoscopic Index of Severity (UCEIS)

Description

Calculates the UCEIS score, a validated instrument for assessing endoscopic disease activity in Ulcerative Colitis. The score is the sum of three descriptors: vascular pattern, bleeding, and erosions/ulcers. The total score ranges from 0 to 8.

Usage

uceis_score(vascular_pattern, bleeding, erosions_ulcers)

Value

A list containing:

UCEIS_Score: The calculated total score (Range 0-8).
Disease_Activity: Interpretation of severity (Remission <=1, Moderate-Severe >4).

Arguments

vascular_pattern: Numeric (0-2). Assessment of vascular pattern. 0: Normal. 1: Patchy obliteration. 2: Obliterated.
bleeding: Numeric (0-3). Assessment of bleeding. 0: None. 1: Mucosal. 2: Luminal mild. 3: Luminal moderate or severe.
erosions_ulcers: Numeric (0-3). Assessment of erosions and ulcers. 0: None. 1: Erosions. 2: Superficial ulcer. 3: Deep ulcer.

# Example 1: Severe Disease
# Obliterated vascular (2), Luminal mild bleeding (2), Deep ulcers (3)
# Score = 7
