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).
