BACKGROUND: Hospital-acquired infections account for a substantial increase in morbidity and mortality. This prospective, single-center observational study was conducted to assess the incidence and analyze the risk factors of nosocomial infection after peripheral arterial bypass surgery. METHODS: The incidence of nosocomial infections was registered in all patients undergoing peripheral arterial bypass surgery from January 1996 until December 2004, and risk factors for the development of a nosocomial infection were analyzed. RESULTS: A total of 67 infections were diagnosed in association with 607 procedures, yielding an infection ratio of 10.0%. Surgical site infection was the most common (55.2%), followed by urinary tract infection (16.4%), pneumonia (14.9%) and bacteremia (10.4%). Staphylococcus aureus was the most commonly found isolate in surgical site infections (48.6%) and in bacteremia (42.9%). Age, the use of corticosteroids (p = 0.02), and critical ischemia with tissue loss (p = 0.009) could be identified as risk factors for the development of a nosocomial infection. Blood transfusion was a postoperative risk factor for nosocomial infection (p < .0001). Nosocomial infection was associated with a prolonged hospital stay (p < .0001). CONCLUSIONS: This study provides a detailed description of the incidence and risk factors regarding nosocomial infection. More detailed studies are necessary to develop strategies to diminish the occurrence of nosocomial infection.
