Importance of relying on examples for both anesthesiologists and other physicians to assign unbiased American Society of Anesthesiologists Physical Status Classifications

In this month's issue of the Journal of Clinical Anesthesia, Curatolo and colleagues compare American Society of Anesthesiologists' Physical Status (ASA PS) scoring by anesthesiologists and internal medicine physicians [1]. Using 20 cases (scenarios), they showed that internists assigned significantly lower ASA PS scores than did anesthesiologists [1]. The internists "had a 30–40% chance of under-rating the ASA PS of the patients in the clinical vignettes" compared with the anesthesiologists [1].
