ariscat_score: 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)

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.

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).

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)
