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)

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).

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.
