SUMMARYThis 10-year retrospective study assessed the epidemiology and outcomes of patients withFusobacteriumbacteraemia (FB) at a tertiary-care hospital in the USA – this is the second study focusing on FB in adults to be conducted in the USA in 30 years. Demographic, clinical, laboratory, treatment, and outcome data were collected and statistically analysed. Nineteen patients with FB were identified, representing 0·11% of bacteraemia cases. Mean age was 58·6 years with equal gender distribution. Common comorbidities included cardiovascular disease (CVD) and immunosuppression. Thirty-day mortality was 21·1%, and 68·4% of FB patients required intensive care unit (ICU) admission. Elevated creatinine levels and mental status changes were associated with higher mortality (P = 0·0181 and 0·0374, respectively). CVD, diabetes, and ICU admission were associated with increased length of hospital stay (P = 0·0017, 0·0010, and 0·0379, respectively). The prevalence of FB at our hospital was very low, with poor outcomes associated with increased creatinine level, mental status changes, CVD, diabetes and ICU admission.
