pediatric_appendicitis_score: Pediatric Appendicitis Score (PAS)

Description

Calculates the Pediatric Appendicitis Score (PAS), also known as the Samuel Score, to stratify the risk of acute appendicitis in children presenting with abdominal pain. The score ranges from 0 to 10 and categorizes patients into low, intermediate, or high risk groups.

Usage

pediatric_appendicitis_score(cough_hop_pain, anorexia, temperature_c,
                             nausea_vomiting, rlq_tenderness, wbc_count,
                             neutrophil_percent, migration_of_pain)

Value

A list containing:

PAS_Score: The calculated total score (Range 0-10).
Risk_Category: Risk stratification (Low, Intermediate, High).
Recommendation: Clinical guidance based on the score.

Arguments

cough_hop_pain: Numeric (0 or 1). Presence of cough, percussion, or hopping tenderness in the right lower quadrant. (1 = Yes, +2 points).
anorexia: Numeric (0 or 1). Presence of anorexia. (1 = Yes, +1 point).
temperature_c: Numeric. Patient's body temperature in degrees Celsius. (> 38.0 C adds +1 point).
nausea_vomiting: Numeric (0 or 1). Presence of nausea or vomiting. (1 = Yes, +1 point).
rlq_tenderness: Numeric (0 or 1). Tenderness over the right iliac fossa (RLQ). (1 = Yes, +2 points).
wbc_count: Numeric. White blood cell count in cells/uL (e.g., 12000). (> 10,000 adds +1 point).
neutrophil_percent: Numeric. Percentage of neutrophils (polymorphonuclear neutrophilia). (> 75% adds +1 point).
migration_of_pain: Numeric (0 or 1). Migration of pain to the right lower quadrant (RLQ). (1 = Yes, +1 point).

Examples

Run this code


# Example 1: High Risk
# Cough pain, RLQ tenderness, WBC 15k, Neutrophils 80%, Migration, Anorexia
# Score = 2 + 2 + 1 + 1 + 1 + 1 = 8
pediatric_appendicitis_score(1, 1, 37.5, 0, 1, 15000, 80, 1)

# Example 2: Low Risk
# Nausea only, normal labs
# Score = 1
pediatric_appendicitis_score(0, 0, 37.0, 1, 0, 8000, 50, 0)
