Predicting mortality of elderly patients undergoing open heart surgery with delirium using sequential organ failure assessment (SOFA), multi-organ dysfunction (MODS), and logistic organ dysfunction system (LODS) scores

Abstract

PurposeThis study aims to assess the predictive accuracy of SOFA, MODS, and LODS scores in determining the mortality of elderly undergoing open heart surgery with delirium. MethodsA prospective study involved 111 elderly patients who met the inclusion criteria. Data were collected using scoring systems: SOFA, MODS, and LODS. ResultsUpon final follow-up, 86.5 % of the patients had recovered, 13.5 % had died. Sensitivity, specificity, negative, and positive predictive values for predicting mortality in elderly patients were calculated for the SOFA score as 99 %, 73 %, 98 %, and 76 %, respectively. For the MODS score, these values were 95 %, 60 %, 95 %, and 67 %; for the LODS score, they were 92 %, 73 %, 92 %, and 75 %, respectively. The overall accuracy of the three scores—SOFA, MODS, and LODS—was 84 %, 76 %, and 82 %, respectively. ConclusionThe results indicated that the SOFA score exhibited the highest sensitivity and specificity in predicting mortality among elderly individuals
