Evaluation of the updated " score" with Sepsis 3.0 criteria in critically ill patients.

Background: The score proposed in 2009 was calculated on the definition of "severe sepsis", which was removed in the Sepsis 3.0 definition. This study investigated the clinical relevance of score with the updated Sepsis 3.0 definition (CS-3.0) instead of severe sepsis (CS-2009) in the new admitted critically ill patients.

Methods: We performed a retrospective analysis on a single center public database. All patients with ICU stay ≥72 hours were included in this study. The score was calculated based on the data collected on ICU admission. The incidence of invasive candidiasis was determined and its relationship with the CS-2009 and CS-3.0 was studied.

Results: A total of 17,666 patients were identified after screening 58,976 hospital admissions, and 436 cases (2.5%) were diagnosed with invasive candidiasis. In the infection group, the number of patients who met the Sepsis 3.0 criteria was greater than the number of patients with severe sepsis (81.2% 78.4%, P<0.005). The area under curve of the CS-2009 was 0.789 (95% CI: 0.765-0.813) and the CS-3.0 was 0.804 (95% CI: 0.782-0.827).

Conclusions: Our study confirmed the clinical relevance and comparative superiority of the updated score model, using the Sepsis 3.0 definition, compared with the classic sepsis/severe sepsis model, in assessment of critically ill patients. Considering the clinical importance of organ dysfunction in ICI, the Sepsis 3.0 should be used as the basis for prediction of invasive candidiasis.
