Is the Parsonnet's score a good predictive score of mortality in adult cardiac surgery: assessment by a French multicentre study.

Objecti6e: Parsonnet proposed a preoperative score (‘‘initial Parsonnet’s score’’, which predicts the hospital mortality of adult cardiac surgery. This score was then modified by including several risk factors used in the ‘SUMMIT’ system (‘‘modified Parsonnet’s score’’, 44 variables). We wanted to assess the predictive value of these two scores in a French surgical population. Methods: From December 1992 to April 1993, in France, we organised a prospective multicentre study on adult cardiac surgery mortality and morbidity. Data on 6649 patients were included. We analysed statistically the predictive value of each risk factor and of the two scores on mortality and morbidity at one month. Res…
