title: Inappropriate antibiotic therapy in febrile cancer patients with bacteremia.
abstract: OBJECTIVE
  The aim of the study was to assess the outcome of inappropriately treated cancer patients with documented bacteremia.
  
  
  METHODS
  95 cases of inappropriately treated bacteremias in febrile cancer patients in a tertiary-care center were analyzed and compared with a group of appropriately treated bacteremias to assess risk factors for inappropriate therapy and outcome.
  
  
  RESULTS
  Among 285 bacteremias, 95 (33.3%) were not treated appropriately, with 42 receiving the wrong antibiotics and 17 having too short a therapeutic course of appropriate antibiotics. In 13, therapy was delayed for more than 48 hours after the onset of fever. Twenty-three patients did not receive antibiotic therapy at all despite bacteremia. A group of 95 inappropriately treated bacteremias was compared to 190 appropriately treated bacteremias occurring in the same period. Microbiological cure after the initial course of therapy was achieved more often (76.8% vs 38.9%, P < .001) in the group of appropriately treated bacteremias in all cases and also in the subgroup of leukemic patients (P < .01). Overall and attributable mortality were significantly lower in patients who were treated appropriately. There was no difference in the number of antibiotics administered in appropriately versus inappropriately treated bacteremias. Cost of therapy between both groups was similar.
  
  
  CONCLUSIONS
  Inappropriately treated bacteremic cancer patients had outcomes that were significantly worse than patients who were treated appropriately. The reasons for inappropriate therapy were selection of the wrong antimicrobials, too short a duration of therapy, delayed onset of therapy, or absence of antimicrobial therapy.
