![]() However, due to the classification system’s largely subjective nature, there is inconsistent assignment of ASA physical status among clinicians. The American Society of Anesthesiologists (ASA) physical status classification system was originally designed and implemented as a tool to summarize preoperative comorbidity status, and is now widely used in improving risk adjustment, determining reimbursement, and predicting perioperative risk and mortality, despite the explicit recommendation from the ASA House of Delegates that it not be used in isolation for risk stratification and mortality prediction. Additionally, compared to ASA physical status and individual comorbidity indices, the derived model offered better predictive power in terms of short-term postoperative mortality. ![]() This demonstrates the reliability of ASA scoring and its potential ability to predict postoperative outcomes. ![]() We found significant correlation between ASA physical status and 27 of the 31 Elixhauser comorbidities, as well other demographic characteristics. Furthermore, the model derived from the primary analysis was a better predictor of 30-day mortality than the models including either single ASA physical status or comorbidity indices in isolation (p < 0.001). Older patient (adjusted odds ratio, 1.39 95% CI 1.37 to 1.41), male patient (adjusted odds ratio, 1.24 95% CI 1.20 to 1.29), higher body weight (adjusted odds ratio, 1.08 95% CI 1.07 to 1.09), and ASA emergency status (adjusted odds ratio, 2.11 95% CI 2.00 to 2.23) were also independently associated with higher ASA physical status assignments. Twenty-seven Elixhauser comorbidities were independently associated with ASA physical status. A secondary analysis was then conducted to evaluate the capability of the model to predict 30-day postoperative mortality.Ī total of 56,820 cases meeting inclusion criteria were analyzed. A multivariable ordinal logistic regression model was developed to examine the relationship between the ASA physical status and Elixhauser comorbidity groups. This is a single medical center, retrospective cohort study of adult patients who underwent surgery between Novemand April 22, 2020. In this study, we aimed to assess the correlation between the ASA physical status assignment and more objective measures of overall illness. However, the ASA Physical Status Classification System has been criticized for its subjective nature. ![]() The American Society of Anesthesiologists (ASA) Physical Status Classification System has been used to assess pre-anesthesia comorbid conditions for over 60 years. ![]()
