Clinical Data
Clinical data from survivors were extracted from the electronic medical record. Time from diagnosis was calculated based on the difference from day of enrollment and date of diagnosis. Cyclophosphamide equivalent dose was calculated based on the method of Green, et al [30]. Total days of broad spectrum antibiotics was determined based on the total number of days of the following intravenous agents: ampicillin/sulbactim, aztreonam, cefepime, ceftazidime, ceftriaxone, ciprofloxacin, clindamycin, imipenem, meropenem, Metronidazole, piperacillin/ tazobactam, and vancomycin, received from the time of diagnosis to completion of therapy (or day 100 for transplantation patients).
