This trial uses an interview and a survey to gather information from cancer patients about the onset of their fever and the administration of antibiotics. Collecting information from patients may help doctors to assess the relationship between time to antibiotic administration and inhospital cause specific death, intensive care unit admission, hospital length of stay, and positive blood cultures.

PRIMARY OBJECTIVES:

I. To assess the prognostic value of the length of time between the time onset of fever and first antibiotic administration on cause specific 14 day mortality rate.

SECONDARY OBJECTIVES:

I. To assess the associations of the length of time between the time onset of fever and first antibiotic administration with intensive care unit (ICU) admission, ICU length of stay, length of hospitalization and percentage of patients with positive blood cultures.

OUTLINE:

Patients respond to a survey and participate in an interview with study staff about their fever and when they started feeling unwell.
