National Surgical Quality Improvement Program (NSQIP) Risk Factors Can Be Used to Validate American Society of Anesthesiologists Physical Status Classification (ASA PS) Levels

摘要

The American Society of Anesthesiology's Physical Status Classification (ASA PS) is known to be a strong predictor of surgical outcomes. However, the ASA PS is limited because it lacks clinical precision and is inconsistently applied by different anesthesiologists. The National Surgical Quality Improvement Program tracks 60 preoperative risk factors, including the ASA PS. This study demonstrates that the other 59 risk factors are effective in predicting ASA PS and therefore can be used to validate ASA PS levels by hospital or anesthesiologist.
