ARISCAT Score for Postoperative Pulmonary Complications predicting risk of pulmonary complications after surgery, including respiratory failure.
Predicting risk of pulmonary complications for patients undergoing surgery under general, neuraxial, or regional anesthesia.
ARISCAT Score is calculated by adding up the selected points: Variable Criteria Points Age, years ≤50 0 51-80 3 >80 16 Preoperative SpO2 ≥96% 0 91-95% 8 ≤90% 24 Respiratory infection in the last month* No 0 Yes 17 Preoperative anemia (Hgb ≤10 g/dL) No 0 Yes 11 Surgical incision Peripheral 0 Upper abdominal 15 Intrathoracic 24 Duration of surgery <2 hrs 0 2-3 hrs 16 >3 hrs 23 Emergency procedure No 0 Yes 8 The scores can be interpreted as: ARISCAT Score Risk group Risk of in-hospital postoperative pulmonary complications* <26 Low 1.6% 26–44 Intermediate 13.3% ≥45 High 42.1% *Complications were defined as a composite including respiratory failure, respiratory infection, pleural effusion, atelectasis on chest x-ray, pneumothorax, bronchospasm treated with bronchodilators, and aspiration pneumonitis.
