Cardiac Anesthesia Risk Evaluation (CARE) Score

Description

Calculates the CARE score to predict in-hospital mortality and morbidity after cardiac surgery. This score categorizes patients into one of five risk classes based on the presence of specific preoperative risk factors, prioritizing the most severe condition present.

Usage

cardiac_anesthesia_risk_evaluation(history_cardiac_surgery, complex_surgery,
                                   uncontrolled_medical_condition, emergency_surgery)

Arguments

history_cardiac_surgery	Numeric (0 or 1). Prior cardiac surgery. (1 = Yes). This assigns a base score of 2.
complex_surgery	Numeric (0 or 1). Surgery other than isolated CABG (e.g., valve, aortic, or combined procedures). (1 = Yes). This assigns a base score of 3.
uncontrolled_medical_condition	Numeric (0 or 1). Presence of uncontrolled medical conditions (e.g., active heart failure, acute MI <7 days, unstable angina). (1 = Yes). This assigns a base score of 4.
emergency_surgery	Numeric (0 or 1). Surgery required immediately to save life or limb. (1 = Yes). This assigns a base score of 5.

Details

The scoring is hierarchical. A patient is assigned the highest score for which they meet the criteria: Score 5: Emergency surgery. Score 4: Uncontrolled medical condition (if not Emergency). Score 3: Complex surgery (if not Emergency or Uncontrolled). Score 2: Prior cardiac surgery (if not the above). Score 1: Routine case (none of the above).

Value

A list containing:

CARE_Score	The calculated risk class (1-5).
In_Hospital_Mortality_Risk	Estimated mortality percentage.
Morbidity_Risk	Estimated morbidity percentage (e.g., stroke, renal failure, prolonged ventilation).

Examples

# Example 1: Routine CABG (No risks)
# Score = 1
cardiac_anesthesia_risk_evaluation(0, 0, 0, 0)

# Example 2: Emergency Surgery
# Regardless of other factors, Emergency = Score 5
cardiac_anesthesia_risk_evaluation(1, 1, 1, 1)

# Example 3: Valve Surgery (Complex) with no other uncontrolled conditions
# Score = 3
cardiac_anesthesia_risk_evaluation(0, 1, 0, 0)
