Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) Score for Postoperative Pulmonary Complications

Key Points

To evaluate the efficacy of the ARISCAT score in predicting postoperative pulmonary complications in surgical patients.
Assessment of ARISCAT score with data from surgical patients in Catalonia.
Review of validation studies comparing ARISCAT with other clinical variables.
Analysis of the score's utility in different types of surgeries, including cardiothoracic.
ARISCAT effectively predicts postoperative pulmonary complications in general and abdominal surgeries.
Systematic reviews indicate minor calibration shifts and limitations in cardiothoracic settings.
Inclusion of albumin and ASA status could enhance risk stratification.

Abstract

ARISCAT is a widely used preoperative assessment tool that predicts the overall risk of postoperative pulmonary complications following surgery requiring general, neuraxial, or regional anesthesia. Numerous validation studies have demonstrated efficacy in risk stratification prior to general and abdominal surgery. However, caution is warranted when using ARISCAT alone due to recent systematic reviews and meta-analyses that noted minor calibration shifts in these validation studies. The score has limited utility in cardiothoracic surgical settings but adding other clinical variables, such as albumin and ASA status, may improve risk stratification.
