Key result
The Parsonnet score predicted hospital mortality after cardiac surgery with higher discrimination (AUC 0.857) than general severity systems such as APACHE II (AUC 0.803).
Why the study?
Do general severity systems predict hospital mortality as well as the Parsonnet score in cardiac surgery patients?
Population
465 cardiac surgery patients in a tertiary referral center
Comparison

Do general severity systems predict hospital mortality as well as the Parsonnet score in cardiac surgery patients?
Effect estimate: AUC 0.857
The Parsonnet score outperforms general severity systems (APACHE, SAPS, MPM) in predicting hospital mortality after cardiac surgery.
Martinez-Alario et al. (1999) conducted an observational in Cardiac surgery (n=465). Parsonnet score vs. General severity systems (APACHE II, SAPS II, MPM II0, MPM II24) was evaluated on Hospital death (AUC 0.857). The Parsonnet score predicted hospital mortality after cardiac surgery with higher discrimination (AUC 0.857) than general severity systems such as APACHE II (AUC 0.803).
