A cancer patient with febrile neutropenia should be treated with antibiotics as long as they are needed. The duration of antibiotic therapy depends on a number of clinical factors. The authors are from the Infectious Diseases Society of America (IDSA) and multiple hospitals in the North America and Europe.
Parameters:
(1) presence of fever after initial empirical therapy for 3 to 5 days
(2) absolute neutrophil count (ANC)
(3) initial risk of infection
(4) current clinical status
