car_olt_score: Cardiovascular Risk in Orthotopic Liver Transplantation (CAR-OLT)

Description

Structures the inputs for the CAR-OLT risk score, a tool designed to predict the 1-year risk of major adverse cardiovascular events (MACE) following orthotopic liver transplantation. The score uses 12 pre-transplant characteristics to stratify candidates, helping to identify those who may require further cardiac testing versus those (Low Risk, score <= 23) who may proceed safely.

Usage

car_olt_score(age, sex, race, employment_status, education_level,
              history_hcc, diabetes, heart_failure, atrial_fibrillation,
              pulmonary_hypertension, systemic_hypertension, respiratory_failure)

Value

A list containing:

Inputs

The formatted list of patient risk factors.

Risk_Threshold

Interpretation based on the published low-risk cutoff (<= 23).

Arguments

age

Numeric. Recipient age in years.

sex

String. "Male" or "Female".

race

String. Recipient race (e.g., "White", "Black", "Other").

employment_status

String. "Working" or "Not Working".

education_level

String. "College" or "High School or Less".

history_hcc

Numeric (0 or 1). History of Hepatocellular Carcinoma. (1 = Yes).

diabetes

Numeric (0 or 1). History of Diabetes Mellitus. (1 = Yes).

heart_failure

Numeric (0 or 1). History of Heart Failure. (1 = Yes).

atrial_fibrillation

Numeric (0 or 1). History of Atrial Fibrillation. (1 = Yes).

pulmonary_hypertension

Numeric (0 or 1). History of Pulmonary Hypertension. (1 = Yes).

systemic_hypertension

Numeric (0 or 1). History of Systemic Hypertension. (1 = Yes).

respiratory_failure

Numeric (0 or 1). Respiratory failure (on ventilator) at time of transplant. (1 = Yes).
