Role of Thoracoscore and ESOS in Prediction of Outcomes after Thoracic Surgeries

ABSTRACT Background The use of scores in thoracic surgery has been done recently. European Society Objective Score (ESOS) and Thoracoscore are the most popular scores used in thoracic operations. This work aimed to compare ESOS and Thoracoscore’s ability in predicting the mortality after thoracic surgery. Methods This retrospective study involved 282 cases who were admitted to thoracic surgery unit, Tanta University Hospitals and other hospitals whose Thoracoscore and ESOS were calculated from January 2017 to December 2022. Results Mortality rate at 30 days postoperative was 7.44% in our study. Pneumonectomy and MV (mechanical ventilation) were significantly associated with mortality (P value < 0.001). Thoracoscore can predict mortality (P value = 0.004 and AUC = 0.629) with 61.9% sensitivity, 56.70% specificity, 10.3% positive predictive value (PPV), and 94.9% negative predictive value(NPV). ESOS can predict mortality (P value = 0.006 and AUC = 0.662) with 85.71% sensitivity, 37.55% specificity, 9.9% PPV and 97% NPV. ESOS was an independent significant predictor for mortality while Thoracoscore was not. Conclusions ESOS and Thoracoscore are applicable tools in predicting the mortality after thoracic surgeries. However, ESOS is more sensitive and more specific.
