1474. Epidemiology and Outcomes of Hospitalized Patients with Urinary Tract Infections (UTI) Due to Multidrug-Resistant Organisms (MDRO)

Background MDROs are a threat to public health, and UTIs are the most common type of MDRO infection. The objective of this study was to describe risk factors and outcomes associated with MDRO UTIs. Methods A retrospective cohort study with IRB approval from Barnes-Jewish Hospital, January 1, 2006–November 8, 2017. Demographics, comorbidities, procedures, outcomes, and culture data were collected from the BJC Healthcare Informatics database for hospitalized patients with MDRO UTIs. MDROs were defined according to European and US CDC standards. Results A total of 7,945 hospitalized patients with MDRO UTI were identified. Demographics and comorbidities are described in Table 1. Notably, 69% of patients were female, 23% had underlying urinary system disease, and at least 20% had a foley catheter in place. Of these patients, 18% required an intensive care unit (ICU) stay within 48 hours before/after the positive urine culture, and 7% died during their hospitalization (Table 2). The most frequent cause of UTIs was MDR Enterobacteriaceae (Table 3). Conclusion Patients who are hospitalized with MDRO UTIs frequently have underlying urinary system disease and/or foley catheter. MDRO UTIs are a significant cause of morbidity and mortality in hospitalized patients, with 18% requiring an ICU stay, and death in 7% during the hospitalization. Further research is needed regarding risk factors and interventions to prevent, detect, and treat MDRO UTIs. Disclosures All authors: No reported disclosures.
