pe_sard_bleeding_score: PE-SARD Bleeding Risk Score

Description

Calculates the PE-SARD (Pulmonary Embolism - Syncope, Anemia, Renal Dysfunction) Score to predict the risk of early major bleeding in patients with acute pulmonary embolism. The score stratifies patients into Low, Intermediate, and High risk groups.

Usage

pe_sard_bleeding_score(hemoglobin, syncope, egfr)

Value

A list containing:

PE_SARD_Score

The calculated risk score (Range 0-5).

Risk_Class

Risk classification (Low: 0, Intermediate: 1-2.5, High: >2.5).

Est_Major_Bleeding_Risk

Estimated probability of early major bleeding.

Arguments

hemoglobin

Numeric. Hemoglobin level in g/dL. (<12 g/dL adds 2.5 points).

syncope

Numeric (0 or 1). History of syncope at presentation? (1 = Yes, +1.5 points).

egfr

Numeric. Estimated Glomerular Filtration Rate in mL/min/1.73m^2. (<60 mL/min adds 1 point).

Examples

# Example 1: High Risk
# Hb 11 (2.5), Syncope (1.5), eGFR 50 (1.0)
# Score = 5

# Example 2: Low Risk
# Hb 14 (0), No Syncope (0), eGFR 90 (0)
# Score = 0
