EuroSCORE II for Risk Evaluation and Predicting Cardiac Intensive Care Length of Stay in Indian Patients Undergoing Adult Cardiac Surgery

Abstract

BackgroundHigher EuroSCORE II values are usually associated with increased postoperative morbidity and longer durations of Cardiac intensive care unit (CICU) stay following cardiac surgery.Aim/PurposeThe aim is to investigate the predictive performance of EuroSCORE II for the Indian population and its relationship with ICU length of stay.MethodsProspective, observational study in 250 adult cardiac patients undergoing CABG under general Anaesthesia. Preoperatively values of EuroSCORE II was calculated by an online calculator available on www.euroscore.org. These patients were followed up after surgery for 30 days to note mortality and length of CICU stay.ResultsOf 250 cases studied, 39 (15.6%) had EuroSCORE II less than 1, 163 (65.2%) had EuroSCORE II between 1 and 3, 36 (14.4%) had EuroSCORE II between 3.1 and 5.0 and 12 (4.8%) had EuroSCORE II more than 5 in the study group. Mean EuroSCORE II and length of stay in CICU after surgery was 2.2 ± 1.4 and 4.2 ± 2.5 days respectively. The area under the curve (AUC) for EuroSCORE II as a sole predictor of mortality in the study group based on receiver operating characteristic curve (ROC) analysis was 0.919 (95% CI 0.86–0.97). Based on ROC analysis, AUC is significantly higher for predicting mortality (p < 0.001).ConclusionEuroSCORE II in Indian cardiac patients undergoing cardiac surgery is lesser than in European patients (mean 2.2 vs 3.7). Incidence of mortality is higher in patients with higher EuroSCORE II. As per our study patients with higher EuroSCORE II tend to stay longer in ICU.
