Pediatric Ulcerative Colitis Activity Index (PUCAI)

Description

Calculates the PUCAI score to assess disease activity in pediatric patients with ulcerative colitis. The score is based on six clinical items: abdominal pain, rectal bleeding, stool consistency, number of stools per 24 hours, nocturnal stools, and activity level limitation.

Usage

pucai_score(abdominal_pain, rectal_bleeding, stool_consistency, stools_per_24h,
            nocturnal_stools, activity_level)

Arguments

abdominal_pain	Numeric. Score for abdominal pain: 0 (None), 5 (Ignoreable), 10 (Severe).
rectal_bleeding	Numeric. Score for rectal bleeding: 0 (None), 10 (Small amount/ <50% of stools), 20 (Large amount/ >=50% of stools), 30 (Daily). Note: Specific point assignments vary slightly by source definition (e.g., 0, 10, 20, 30 is common).
stool_consistency	Numeric. Score for stool consistency: 0 (Formed), 5 (Partially formed), 10 (Completely unformed).
stools_per_24h	Numeric. Score for number of stools per 24 hours: 0 (0-2), 5 (3-5), 10 (6-8), 15 (>8).
nocturnal_stools	Numeric. Score for nocturnal stools: 0 (No), 10 (Yes).
activity_level	Numeric. Score for activity level: 0 (No limitation), 5 (Occasional limitation), 10 (Severe limitation).

Value

A list containing:

PUCAI_Score	The calculated total score (Range 0-85).
Disease_Activity	Classification of disease severity (Remission <10, Mild 10-34, Moderate 35-64, Severe >=65).

# Example 2: Severe Disease
# Pain(10), Bleeding(30), Consistency(10), Freq(15), Nocturnal(10), Activity(10)
# Score = 85
