Mortality in Emergency Department Sepsis score as a prognostic indicator in patients with pyogenic liver abscess

Abstract Objectives The purpose of this study was to explore the predictor index of mortality in patients with pyogenic liver abscess (PLA). Methods We performed a retrospective review that enrolled 431 patients 18 years and older hospitalized due to PLA between January 2005 and December 2010. Clinical characteristics, laboratory results, treatments, and outcomes retrieved from medical records were analyzed. Multiple logistic regression and receiver operating characteristic curve analyses were performed. Results The mean age of the 431 patients identified with PLA was 56.9 ± 15.0 years. The mean Mortality in Emergency Department Sepsis (MEDS) score on admission was 4.8 ± 4.1 (range, 0-17). During hospitalization, 94 patients (22%) required intensive care. Of the 431 patients, 63 died, yielding a 15% case fatality rate. Multivariate analysis revealed that higher MEDS scores on admission ( P P = .006), multiple abscesses ( P = .001), anaerobic infections ( P P P P P P Conclusions The MEDS scores on admission represent a significant prognostic indicator for patients with PLA.
