evendo_esophageal_varices_score: EVendo Score for Esophageal Varices Screening

Description

Structures the clinical inputs for the EVendo score, a predictive tool for identifying esophageal varices in patients with cirrhosis. The score utilizes Platelet count, INR, and Serum Urea to risk-stratify patients and determine the necessity of screening endoscopy.

Usage

evendo_esophageal_varices_score(platelet_count, inr, urea, urea_units = "mg/dL")

Value

A list containing:

Risk_Factors_Present: Count of abnormal parameters (Low Platelets, High INR, High Urea).
Interpretation: General clinical guidance based on the presence of risk factors.
Inputs: Standardized input values.

Arguments

platelet_count: Numeric. Platelet count in 10^9/L (or x1000/uL).
inr: Numeric. International Normalized Ratio.
urea: Numeric. Serum Urea level.
urea_units: String. Units for the urea input. Options: "mg/dL" (Urea), "BUN_mg_dL" (BUN to be converted), "mmol/L" (Urea SI units).

Examples

Run this code


# Example 1: High Risk
# Plt 80, INR 1.8, Urea 50 mg/dL
evendo_esophageal_varices_score(80, 1.8, 50)

# Example 2: Low Risk
# Plt 200, INR 1.0, Urea 20 mg/dL
