ASA variability warrants caution in sole reliance for risk assessment; leaves open standardization of perioperative classification systems.
Cross-Sectional (n=97)
There is significant variation between individual anaesthetists' assessments of ASA physical status classification, suggesting the grade alone cannot satisfactorily describe a patient's physical status.
Haynes et al. (1995) reported a cross-sectional. ASA Physical Status Classification was evaluated on Consistency of ASA grade allocation to 10 hypothetical patients. Allocation of ASA physical status classification by anaesthetists showed significant variation, with no complete agreement on ASA grade for any of the 10 hypothetical patients.
