Evaluation of qSOFA as a Predictor of Mortality Among ICU Patients With Positive Clinical Cultures—A Retrospective Cohort Study

Objective: To compare the discriminative value of the quick-sequential organ failure assessment score (qSOFA) to SOFA in a critically ill population, in which a microbial pathogen was isolated within 48 hours of admission to intensive care. Design: Retrospective cohort study. Setting: Academic tertiary referral center from July 2008 to June 2017. Patients: Hospitalized patients admitted to intensive care unit. Interventions: None. Measurements and Main Results: The primary outcome was in-hospital mortality for all patients with confirmed positive microbiological cultures within 48 hours of admission to intensive care unit (ICU). Subgroup analysis was performed on patients with pathogenic bacteremia or positive cultures in cerebrospinal fluid. Of the 11 415 patients analyzed with positive microbiology specimens within 48 hours of admission, 2933 (25.7%) had a qSOFA ≥2. Of these, 16.6% reached the primary outcome of in-hospital mortality. Unsurprisingly, the discriminative value of qSOFA on admission was significantly worse than that of SOFA (0.73 vs 0.76; P = .0004), despite observing a significant association between qSOFA category and in-hospital mortality ( P < .0001). In secondary analyses, similar observations were found using qSOFA within 6 and 24 hours of ICU admission. When analysis was focused on patients with pathogenic bacteremia or positive cerebrospinal fluid (CSF) cultures (n = 1646), there was no significant difference between the discriminative value of qSOFA and SOFA (0.75 vs 0.78; P = .17). Conclusions: Quick-sequential organ failure assessment score at admission was not superior to SOFA in predicting in-hospital mortality in patients with positive clinical cultures within 48 hours of admission to ICU. Quick-sequential organ failure assessment score at admission to the ICU was associated with mortality and showed reasonable calibration and discrimination. When the analysis was focused on patients with pathogenic bacteremia or positive CSF cultures, qSOFA performed similarly to SOFA in discriminatory those who will die from sepsis.

Background Hospital admissions with decompensated chronic alcoholic liver disease have been increasing, leading to increased pressure on intensive care unit services. We aimed to determine the outcome and prognostic factors for patients with alcoholic liver disease requiring admission to intensive care unit. Methods This was a retrospective study over 5 years (January 2006–December 2010) of all intensive care unit admissions with alcoholic liver disease to either of the two Leeds Teaching Hospitals NHS Trust general intensive care units. A detailed case note review was conducted based on a pre-established proforma. Eighty-two patients included. Primary outcome was hospital mortality. Results The overall intensive care unit and hospital mortality were 46% and 67%, respectively. Hospital mortality in patients successfully discharged from intensive care unit with the intent of recovery remained high at 21%. Variceal bleed was the only indicator that had a mortality <60%. Factors which suggested a poor outcome included sepsis (86% mortality) and hepato-renal syndrome (86% mortality). A Sequential Organ Failure Assessment score of greater than 10 on intensive care unit admission was associated with 97% hospital mortality. Sequential Organ Failure Assessment score increased from a mean of 10.9–12.5 in those that did not survive hospital. Patients with first alcoholic liver disease related admission had poorer outcomes. Conclusion These results are similar to previous studies with no significant improvement in outcomes. Alcoholic liver disease is not a contra-indication to intensive care unit admission but assessment of the individual patient is required. The most appropriate objective factors to guide prognostication are the presenting intensive care unit diagnosis and Sequential Organ Failure Assessment score. First presentation of alcoholic liver disease is not a positive prognostic indicator.
