Prognostic factors of health care-associated bloodstream infection in adult patients ≥40 years of age

We investigated 401 geriatric patients and 453 middle-aged patients with health care-associated bloodstream infection (HABSI) at a medical center during January-December 2014. Compared with middle-aged patients, the geriatric group had higher 30-day mortality (31.2% vs 23.4%, P = .01). Body mass index, serum albumin concentration, Charlson comorbidity index score, vancomycin-resistant Enterococcus bacteremia, and high C-reactive protein levels predict poor outcomes for HABSI among adult patients.
