ASA classification and perioperative variables as predictors of postoperative outcome

Abstract: In a prospective study of 6301 surgical patients in a university hospital, we examined the strength of association between ASA physical status classification and perioperative risk factors, and postoperative outcome, using both univariate analysis and calculation of the odds ratio of the risk of developing a postoperative complication by means of a logistic regression model. Univariate analysis showed a significant correlation (P : 0.05) between ASA class and perioperative variables (intraoperative blood loss,… Show more

“…The independent risk factors of severe complications, death or coma within 24 h of anaesthesia include patient's age, number of associated diseases, pre-operative status, emergency surgery and the duration of procedure [21]. While the ASA physical status was not originally intended to be used as an estimate of 'operative risk' [24], it is a predictor of postoperative outcome [25]. After-hours procedures are usually performed by junior trainee surgeons and this was a factor associated with peri-operative deaths in an early Confidential Enquiry into Perioperative Deaths (CEPOD) study [26].…”

“…Elas vêm sendo formuladas há várias décadas, de modo que, identificando pacientes de alto risco, pode-se prepará-los da melhor maneira possível, tentando evitar, assim, que desenvolvam tais complicações [10][11][12][13] . Além disso, uma escala padronizada permite comparar e avaliar os resultados de diferentes serviços e em diferentes períodos dentro de um mesmo serviço.…”
