The role of extended-spectrum beta-lactamase (ESBL)-producing or multidrug-resistant (MDR) organisms in patients with sepsis secondary to urinary traction infection (UTI) has not been investigated extensively in the intensive care unit (ICU) setting.
Patients with UTI sepsis admitted to the ICU were retrospectively enrolled in this study (January 2009-December 2012). We investigated the impact of ESBL-producing and ESBL-negative MDR organisms on hospital outcome.
In total, 94 patients were enrolled (median age, 73.0 years; female, 81.9%), and ESBL-producing and ESBL-negative MDR organisms accounted for 20.2% (n = 19) and 30.9% (n = 29), respectively. Both patients with ESBL-producing and ESBL-negative MDR organisms were more likely to experience a delay in adequate antibiotic therapy than those with non-ESBL/non-MDR organisms (p < 0.001 and p = 0.032, respectively). However, only patients with ESBL-producing organisms showed a higher mortality rate (ESBL vs. ESBL-negative MDR vs. non-ESBL/non-MDR, 31.6% vs. 10.3%.vs. 10.9%, respectively). In multivariate analyses, ESBL production was significantly associated with hospital mortality (odds ratio, 11.547; 95micro confidence interval, 1.047-127.373), and prior admission was a significant predictor of ESBL production.
Although both ESBL-producing and ESBL-negative MDR organisms are associated with delayed administration of appropriate antibiotics, only ESBL production is a significant predictor of hospital mortality among patients with UTI sepsis in the ICU setting.
