ARISCAT Score for Postoperative Pulmonary Complications

Description

Calculates the ARISCAT (Assess Respiratory Risk in Surgical Patients in Catalonia) score to predict the risk of developing postoperative pulmonary complications (PPC) such as respiratory failure, infection, pleural effusion, atelectasis, pneumothorax, bronchospasm, or aspiration pneumonitis.

Usage

ariscat_score(age, spo2, resp_infection_last_month, anemia_hb_le_10,
              incision_site, duration_surgery_hours, emergency_surgery)

Arguments

age	Numeric. Patient age in years.
spo2	Numeric. Preoperative oxygen saturation (%) on room air.
resp_infection_last_month	Numeric (0 or 1). Respiratory infection within the last month. (1 = Yes).
anemia_hb_le_10	Numeric (0 or 1). Preoperative anemia with Hemoglobin <= 10 g/dL. (1 = Yes).
incision_site	String. Location of surgical incision. Options: "peripheral" (0 pts), "upper_abdominal" (15 pts), "intrathoracic" (24 pts).
duration_surgery_hours	Numeric. Expected or actual duration of surgery in hours.
emergency_surgery	Numeric (0 or 1). Is the procedure an emergency? (1 = Yes).

Value

A list containing:

ARISCAT_Score	The calculated score (Range 0-123).
Risk_Group	Risk classification (Low < 26, Intermediate 26-44, High >= 45).
Est_Pulmonary_Complication_Rate	Estimated percentage risk of PPCs.

Examples

# Example 1: High Risk
# 82yo, SpO2 90%, Intrathoracic, >3h surgery
# Score = 16 + 24 + 0 + 0 + 24 + 23 + 0 = 87
ariscat_score(82, 90, 0, 0, "intrathoracic", 3.5, 0)

# Example 2: Low Risk
# 45yo, SpO2 98%, Peripheral, 1h surgery
# Score = 0
ariscat_score(45, 98, 0, 0, "peripheral", 1, 0)
