Is there any difference between SOFA and LODS scores to discriminate outcome in septic patients?


Organ failure scores were designed to describe organ dysfunction more than to predict outcome. The main difference between these systems is how they evaluate cardiovascular dysfunction, which is the main cause of mortality in septic patients.


a) to compare the effectiveness of Sequential Organ Failure Assessment (SOFA) score and of Logistic Organ Dysfunction System (LODS) score to discriminate outcome in septic patients; b) to determine the best cut-off value for both scores.


Prospective, observational study.


Two large general ICUs.


Forty-seven adult septic patients.


We measured SOFA and LODS scores at ICU admission and daily. Survivors and non-survivors median scores for both descriptors were compared using Mann–Whitney U-test; the relative risk (RR) was also calculated.


The mean age was 51 ± 18 years and mean APACHE II was 19.8 ± 6. The best cut-off value for SOFA and LODS score were 11 and 6, respectively. The overall mortality rate was 48.9%.


Both SOFA and LODS score discriminated adequately survivors and non-survivors septic patients.
