Randomized Controlled Trial Multicenter Study
American Society of Anesthesiologists' physical status system: a multicentre Francophone study to analyse reasons for classification disagreement.
Variability of American Society of Anesthesiologists' (ASA) physical status scores attributed to the same patient by multiple physicians has been reported in several studies. In these studies, the population was limited and diseases that induced disagreement were not analysed. ⋯ The degree of agreement between two measures of the ASA physical status grade is moderate and influenced by staff characteristics and the complexity of diseases.
