Nosocomial infections caused by Clostridium difficile, CP-Kp, ESBL-E or Candida spp. are usually associated with a high mortality rate. In this retrospective study, we evaluated the association between the patient characteristics and the risk of development of nosocomial BSI due to Candida or CP-Kp or ESBL-E. Moreover, we described the cumulative incidence of recurrent infections according to each group of nosocomial BSI. Enteral or parenteral nutrition and indwelling CVC at time of diagnosis were associated with an increased risk of candidemia or CP-Kp over ESBL-E and CDI. ESBL-E BSI was higher in patients undergoing hemodialysis, hematological stem cell transplant and neutropenic patients. The cumulative incidence for recurrent infections was higher for CP-Kp BSI and lower for candidemia. Our data highlight a different role of single patient comorbidities in the development of infections and the higher incidence of recurrent infections in CP-Kp BSI.
