Key result
The modified Parsonnet's score was a better predictor of hospital mortality than the initial score (AUC 0.70 vs 0.64; OR per point 1.05 vs 1.01), though both scores remain imperfect.
Why the study?
Does the modified Parsonnet's score better predict hospital mortality and severe morbidity compared to the initial Parsonnet's score in adult cardiac surgery patients?
Population

Yes
Does the modified Parsonnet's score better predict hospital mortality and severe morbidity compared to the initial Parsonnet's score in adult cardiac surgery patients?
Odds Ratio: 1.05
The modified Parsonnet's score predicts hospital mortality better than the initial score in adult cardiac surgery, though its complexity limits clinical utility.
F Gabrielle (1997) conducted a cohort in Adult cardiac surgery (n=6,649). Modified Parsonnet's score vs. Initial Parsonnet's score was evaluated on Hospital mortality and severe morbidity at one month (OR 1.05). The modified Parsonnet's score was a better predictor of hospital mortality than the initial score (AUC 0.70 vs 0.64; OR per point 1.05 vs 1.01), though both scores remain imperfect.
