gwtg_hf_risk_score: GWTG-HF Risk Score for In-Hospital Mortality

Description

Calculates the Get With The Guidelines-Heart Failure (GWTG-HF) risk score to predict in-hospital all-cause mortality in patients hospitalized with heart failure. The score uses admission vitals (SBP, HR), labs (BUN, Sodium), age, COPD history, and race.

Usage

gwtg_hf_risk_score(age, systolic_bp, bun, heart_rate, sodium, copd,
                   race_black = 0, bun_units = "mg/dL", sodium_units = "mEq/L")

Value

A list containing:

GWTG_HF_Score

The calculated risk score (Range 0-100+).

Est_In_Hospital_Mortality

Estimated probability of in-hospital mortality.

Arguments

age

Numeric. Patient age in years.

systolic_bp

Numeric. Admission Systolic Blood Pressure (mmHg).

bun

Numeric. Admission Blood Urea Nitrogen level.

heart_rate

Numeric. Admission Heart Rate (bpm).

sodium

Numeric. Admission Serum Sodium level.

copd

Numeric (0 or 1). History of Chronic Obstructive Pulmonary Disease. (1 = Yes).

race_black

Numeric (0 or 1). Is the patient Black/African American? (1 = Yes, 0 = No). Note: Non-Black race adds points in this model.

bun_units

String. Units for BUN input. "mg/dL" (default) or "mmol/L".

sodium_units

String. Units for Sodium input. "mEq/L" (default) or "mmol/L".
