Introduction. Currently, Surgical Intensive Care Units (SICU) do not have any specific severity of illness scoring method that can be widely used in this environment. For this reason, the aim of this study is to assess the performance (calibration and discrimination) of two prediction models: EuroSCORE II (European System for Cardiac Operative Risk Evaluation II) and MPM III (Mortality Prediction Model III). EuroSCORE II is a risk model specifically validated in patients undergoing major cardiac surgery, whereas MPM III is a scoring system commonly used in the Intensive Care Units (ICU). Analysing these parameters, we can evaluate the performance of the MPM III in the cardiac surgical patient’s prognosis assessment. Material and methods. An observational, retrospective and single-centre study was performed. It included a sample of patients who had undergone major cardiac surgery and were admitted to the SICU during 2020 in the Hospital General Universitario de Alicante (HGUA). Estimated mortality was calculated for each model and it was compared to the observed mortality. The calibration was evaluated with Hosmer-Lemeshow (HL) goodness-of-fit test and discrimination with the area under the ROC (Receiver Operating Characteristic) curve. Results. Two hundred forty-nine patients were included in the study. Observed mortality was 4.4% and the complication rate was 43.8%. The mean expected mortality rate was 6.3% for the MPM III and 3.6% for the EuroSCORE II. Referring to calibration, statistically significant differences were not found between observed and expected mortalities when using MPM III (p=0.5) with a significant odds ratio (OR) of 1.11 (CI 95% = 1.05-1.18), while these differences were found with EuroSCORE II (p=0.05) with a non-significant OR of 1.09 (CI 95% = 0.98-1.21). Areas under the ROC curves (AUC) were 0.76 (CI 95% = 0.70-0.81) for MPM III and 0.72 (CI 95% = 0.66-0.77) for EuroSCORE II. Conclusions. MPM III showed good calibration and acceptably good discrimination in cardiac surgical patients. According to these findings, MPM III could be a useful model in SICU by providing information regarding to mortality and complications prediction in this group of patients.
