PREDICTIVE FACTORS OF IN-HOSPITAL MORTALITY IN OLDER ADULTS WITH COMMUNITY-ACQUIRED BLOODSTREAM INFECTION

Objectives: To assess the prevalence of intra-hospital mortality and associated risk factors in older people aged 75+, admitted with blood stream infections (BSI). Design: Single center retrospective study performed in an 850-bed of the academic hospital of the Université Libre de Bruxelles. Setting and Participants: From January 2015 to December 2017, all inpatients over 75 years old admitted with BSI were included. Measures: Demographical, clinical and microbiological data were collected. Results: 212 patients were included: median age was 82 [79-85] years and 60 % were female. The in-hospital mortality rate was 19%. The majority of microorganisms were Gram-negative strains, of which Escherichia coli was the most common, and urinary tract infection was the most common origin of BSI. Compared to patients who survived, the non-survivor group had a higher SOFA score (6 versus 3, p
