Abstract

Background: Various prediction models have been developed aiming to estimate riskadjustedmortality, morbidity and length of intensive care unit stay following cardiacsurgeries. The European system for cardiac operative risk evaluation II (EuroSCOREII) is a prediction model which maps 18 predictors to a 30-day post-operative risk ofdeath. The objective of this study was to evaluate the performance of the EuroSCOREII risk-analysis predictions among patients who underwent heart surgeries. Methods: A prospective cross-sectional study was conducted to collect requiredvariables for all consecutive patients underwent heart surgeries in Emam Reza hospital, Mashhad, IRAN, from March 2014 to March 2015. Once the patient was hospitalized acardiologist or a general physician evaluated pre-peri-and post-operative state to fillout the pre-designed structural paper form. Comparing the observed and expectedmortality, the sensitivity, specificity, area under the receiver operating characteristiccurve (AUC) and finally the discrimination power of the model for our patients werecalculated and reported. The model value was calculated using the online tool. Results: A total of 1337 patients (60% males) were included, the observed MORTALITYrate was 3. 2%. Although the overall performance was acceptable, the model showedpoor discriminatory power (AUC=0. 667, CI 95%: 0. 648-0. 685) and accuracy withsensitivity=61. 88% and specificity=66. 23%. Conclusion: Our single-center study, based on consecutive patients who underwentCARDIAC SURGERY showed that EuroSCORE II demonstrated a moderate statistical overallperformance with poor discrimination and calibration measures remain as concerningissues regarding 30-day post-operative MORTALITY prediction after adult CARDIAC SURGERY. Poor PERFORMANCE MEASUREs for this system show the need for reformulating this riskstratification tool aiming to improve post CARDIAC SURGERY outcome predictions in IRAN.
