Abstract: Objective: The aim of this study was to investigate the epidemiology and antibiotic \uadsusceptibility profiles of isolated bacterial organisms in relation to empiric treatment of neutropenic fever over a 15-year period. Methods: All patients with or at risk febrile neutropenia and treated in the hematology ward of the Antwerp University Hospital during 19942008 were prospectively included. Skin, blood, and urine cultures were taken. Oral quinolone prophylaxis was started in patients with neutropenia without fever. Empiric starting therapy consisted of amikacin in combination with cefepime. Results: A total of 3624 bacteria were isolated. The most common pathogens were coagulase-negative Staphylococci (46%), followed by Escherichia coli (25%), Enterobacteriaceae (15.6%), Staphylococcus aureus (7.2%), and Pseudomonas aeruginosa (3.8%). The balance between Gram-positive and Gram-negative bacteria remained stable, with a majority of Gram-positive bacteria. A shift from oxacillin-sensitive to oxacillin-resistant coagulase-negative Staphylococci was observed. Regarding susceptibility patterns, no vancomycin resistance was detected in coagulase-negative Staphylococci or in S. aureus. The E. coli susceptibility rates remained stable. However, 66% of bloodstream infections were ciprofloxacin-resistant. A reduced susceptibility of P. aeruginosa strains to meropenem was noticed. Conclusions: Improvement in antibiotic susceptibility of inducible Enterobacteriaceae \uadfollowing a switch of empiric antibiotic therapy was maintained 15 years after starting the \uadlatter treatment. Further improvement in antibiotic susceptibility of these bacteria to ceftazidime was observed, but continuous vigilance is warranted
