PEDIS Score for Diabetic Foot Ulcers

Description

Calculates the PEDIS Score to predict the 6-month risk of non-healing, amputation, or mortality in patients with diabetic foot ulcers. The score aggregates five domains: Perfusion, Extent (size), Depth, Infection, and Sensation.

Usage

pedis_diabetic_foot_score(perfusion_grade, extent_cm2, depth_grade,
                          infection_grade, sensation_grade)

Arguments

perfusion_grade	Numeric. IWGDF Perfusion Grade (1-3). 1: No PAD (Score 0). 2: PAD but no CLI (Score 1). 3: Critical Limb Ischemia (Score 2).
extent_cm2	Numeric. Area of the ulcer in cm^2. 0: Intact (Score 0). <1 cm^2 (Score 1). 1-3 cm^2 (Score 2). >3 cm^2 (Score 3).
depth_grade	Numeric. Depth of the ulcer. 0: Intact (Score 0). 1: Superficial (Score 1). 2: Fascia, muscle, or tendon (Score 2). 3: Bone or joint (Score 3).
infection_grade	Numeric. IWGDF Infection Grade (1-4). 1: None (Score 0). 2: Mild/Surface (Score 1). 3: Moderate/Abscess/Fasciitis (Score 2). 4: Severe/SIRS (Score 3).
sensation_grade	Numeric. Sensation status. 1: Intact (Score 0). 2: Loss of sensation (Score 1).

Value

A list containing:

PEDIS_Score	The calculated total score (Range 0-12).
Risk_Assessment	Interpretation of risk (High Risk >= 7).

Examples

# Example 1: High Risk
# PAD (2->1), >3cm2 (3), Deep (2), Moderate Infection (3->2), No Sensation (2->1)
# Score = 1 + 3 + 2 + 2 + 1 = 9
pedis_diabetic_foot_score(2, 4.0, 2, 3, 2)

# Example 2: Low Risk
# No PAD (1->0), <1cm2 (1), Superficial (1), No Infection (1->0), Intact Sensation (1->0)
# Score = 0 + 1 + 1 + 0 + 0 = 2
