“…In their study, Nashef et al [6] stratified the STS data into quintiles of risk and calculated expected vs. observed mortality. In their commentary on this study, Mandel et al [15] pointed out that the claim that EuroSCORE performs equally well on STS database is not based on statistical evidence. Our study has the advantage of subjecting the data to robust statistical analysis.…”

We compared the performances of the additive European System for Cardiac Operative Risk Evaluation, EuroSCORE (AES) and logistic EuroSCORE (LES) with the Society of Thoracic Surgeons' risk prediction algorithm in terms of discrimination and calibration in predicting mortality in patients undergoing isolated coronary artery bypass grafting (CABG) at a single institution in Pakistan. Both models were applied to 380 patients, operated upon at the Aga Khan University Hospital from August 2009 to July 2010. The actual mortality was 2.89%. The mean AES of all patients was 4.36 ± 3.58%, the mean LES was 5.96 ± 9.18% and the mean Society of Thoracic Surgeons' (STS) score was 2.30 ± 4.16%. The Hosmer-Lemeshow goodness-of-fit test gave a P-value of 0.801 for AES, 0.699 for LES and 0.981 for STS. The area under the receiver operating characteristic curve was 0.866 for AES, 0.842 for LES and 0.899 for STS. STS outperformed AES and LES both in terms of calibration and discrimination. STS, however, underestimated mortality in the top 20% of patients having an STS score >2.88, thus overall STS estimates were lower than actual mortality. We conclude that STS is a more accurate model for risk assessment as compared to additive and logistic EuroSCORE models in the Pakistani population.

“…A comparison between the STS risk scoring system and EuroSCORE was conducted soon after their development. 164 Accuracy variance of the risk scoring systems in different countries seems inevitable. 165 A meta-analysis comparing the STS, EuroSCORE II, and ACEF (Age, Creatinine, Ejection Fraction) scores reported that STS and EuroSCORE II are superior to the ACEF score without a significant difference between STS and EuroSCORE II.…”
