O-9 COMPARISON OF THE PERFORMANCE OF DIFFERENT SCORES FOR THE PREDICTION OF IN-HOSPITAL MORTALITY IN PATIENTS WITH CIRRHOSIS AND BACTERIAL INFECTIONS

Background: Predicting short-term mortality in patients with cirrhosis and bacterial infections is challenging. Aims: To compare the performance of various scores in predicting in-hospital mortality in this population. Methods: We performed an analysis of the multicenter prospective cohort study of patients with cirrhosis with bacterial infections throughout Argentina and Uruguay (clinicatrials.gov.NCT03919032). Patients were classified according to the CLIF criteria as having ACLF or mere acute decompensation (AD). We evaluated the performance of scores of liver disease and infection severity in predicting in-hospital mortality. MELD, MELD-Na, and Quick SOFA (qSOFA) were computed in all patients. CLIF-AD was only computed in patients without ACLF, and CLIF-ACLF only in patients with ACLF. We plotted ROC curves and estimated their area under the curve (AUROC). Results: We included 472 patients: 66% male, mean age 57 ± 12 years. Most frequent infections: SBP (30%) and urinary tract infection (25%). Overall, 332 (70%) patients had acute decompensation, and 140 (30%) ACLF. In-hospital mortality rate was 19%: 41% in patients with ACLF vs 10% in patients with AD (p
