Morbidity and mortality associated with multiple episodes of nosocomial bloodstream infection: a cohort study.
A retrospective cohort study of patients with multiple nosocomial bloodstream infections (BSIs) compared with patients suffering only one BSI was conducted to assess morbidity and mortality. Three hundred forty-one patients with BSIs were identified, including 33 with multiple BSIs (9.7%). No significant differences existed between patients experiencing one BSI compared to those experiencing multiple BSIs in age, sex, race, severity of underlying disease, hypothermia, hypoxemia, oliguria, metabolic acidosis, or hypotension. Sixteen of 33 (49%) with multiple BSIs died compared with 124 of 308 (40%) with only one BSI (P = 0.36), leading to a relative risk of 1.23 for death and an attributable mortality of 9% in those with multiple BSIs.
