SOFA in the first 24 hours as an outcome predictor of acute liver failure - Critical Care Science (CCS)

ABSTRACT

Objective:

To describe a cohort of patients with acute liver failure and to analyze the demographic and clinical factors associated with mortality.

Methods:

Retrospective cohort study in which all patients admitted for acute liver failure from July 28, 2012, to August 31, 2017, were included. Clinical and demographic data were collected using the Epimed System. The SAPS 3, SOFA, and MELD scores were measured. The odds ratios and 95% confidence intervals were estimated. Receiver operating characteristics curves were obtained for the prognostic scores, along with the Kaplan-Meier survival curve for the score best predicting mortality.

Results:

The majority of the 40 patients were female (77.5%), and the most frequent etiology was hepatitis B (n = 13). Only 35% of the patients underwent liver transplantation. The in-hospital mortality rate was 57.5% (95%CI: 41.5 – 73.5). Among the scores investigated, only SOFA remained associated with risk of death (OR = 1.37; 95%CI 1.11 – 1.69; p < 0.001). After SOFA stratification into < 12 and ≥ 12 points, survival was higher in patients with SOFA <12 (log-rank p < 0.001).

Conclusion:

SOFA score in the first 24 hours was the best predictor of fatal outcome.
