pucai_score: 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)

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).

Arguments

abdominal_pain

Numeric. Score for abdominal pain: 0 (None), 5 (Ignoreable), 10 (Severe).

rectal_bleeding
