Modified Model For End-Stage Liver Disease Score Predicts 30-Day Mortality In High-Risk Patients With Acute Pulmonary Embolism Admitted To Intensive Care Units

ObjectivesThe Model for End-stage Liver Disease excluding the international normalised ratio that is derived from prothrombin time which is calculated as a ratio of the patient's prothrombin time to a control prothrombin time standardized (MELD-XI) and modified MELD, which uses albumin in place of the international normalised ratio (MELD-Albumin) scores reflect liver and renal function and are predictors of mortality. However, their prognostic value in acute pulmonary embolism (APE) has not been studied.DesignWe assessed the predictive value of the MELD scores in patients diagnosed with high-risk APE admitted to the intensive care unit. The primary outcome was 30-day mortality.ResultsOf the 273 patients included in the study, 231 were survivors and 42 were non-survivors. The mortality rate was 15.3%. The mean MELD-XI and MELD-Albumin scores were significantly higher in the non-survivors than in the survivors (MELD XI, 11.8 +/- 1.8 and 10.6 +/- 1.43, respectively; p = .002; MELD-Albumin, 10.5 +/- 1.6 and 8.7 +/- 1.1, respectively; p = .001). The multiple logistic regression analysis identified the MELD-XI (hazard ratio: 3.029, confidence interval: 1.06-1.21, p = .007) and MELD-Albumin (hazard ratio: 1.13, confidence interval: 1.06-1.21, p = .002) scores as independent predictors of mortality. Receiver operating characteristic analysis revealed that the predictive power of the MELD-Albumin score (0.871 +/- 0.014; p < .001) was higher than those of the MELD-XI (0.726 +/- 0.022, p < .001), APACHE III (0.682 +/- 0.024, p < .001), and PESI (0.624 +/- 0.023, p < .001) scores.ConclusionsThe MELD-Albumin score is an easily calculable, reliable, and practical risk assessment tool and independent predictor of 30-day mortality in patients with high-risk APE.
