riske_score_cardiac_surgery: RISK-E Score for Cardiac Surgery in Active Infective Endocarditis

Description

Calculates the RISK-E score to predict in-hospital mortality for patients with active infective endocarditis undergoing cardiac surgery. The score is derived from preoperative variables including age, shock (cardiogenic/septic), immunosuppression, renal function, pathogen (S. aureus), and valve characteristics.

Usage

riske_score_cardiac_surgery(age, shock_cardiogenic, shock_septic,
                            immunosuppression, kidney_injury,
                            staphylococcus_aureus, acute_renal_failure_preop,
                            prostheses_involved_count, aortic_valve_involved)

Value

A list containing:

RISKE_Score

The calculated total score (Range 0-~60).

Risk_Category

Classification (Low, Intermediate, High, Very High).

Est_InHospital_Mortality

Estimated in-hospital mortality percentage range.

Arguments

age

Numeric. Patient age in years.

shock_cardiogenic

Numeric (0 or 1). Presence of cardiogenic shock. (1 = Yes, +6 pts).

shock_septic

Numeric (0 or 1). Presence of septic shock. (1 = Yes, +11 pts).

immunosuppression

Numeric (0 or 1). Immunosuppressed status. (1 = Yes, +4 pts).

kidney_injury

Numeric (0 or 1). History of kidney injury or chronic kidney disease. (1 = Yes, +5 pts).

staphylococcus_aureus

Numeric (0 or 1). Causative organism is Staphylococcus aureus. (1 = Yes, +6 pts).

acute_renal_failure_preop

Numeric (0 or 1). Presence of acute renal failure preoperatively. (1 = Yes, +5 pts).

prostheses_involved_count

Numeric. Number of prosthetic valves involved/infected. (>=1 adds 6 pts).

aortic_valve_involved

Numeric (0 or 1). Involvement of the aortic valve. (1 = Yes, +4 pts).
