Fever on chemotherapy: antibiotics within the hour, before the count is back

Give empirical antibiotics within an hour to a febrile patient on chemotherapy, without waiting for the neutrophil count.

Febrile neutropenia can progress to septic shock within hours. Established guidance is to assess a patient on chemotherapy with fever promptly and to give empirical broad-spectrum intravenous antibiotics within an hour of arrival, without waiting for the neutrophil count when neutropenia is likely.

Patients should be told to come in straight away with a fever after chemotherapy, and given written instructions and a contact number. Risk tools such as the MASCC score can then identify the minority suitable for oral or outpatient treatment.

  • Give every patient on chemotherapy written fever instructions and a 24-hour contact number.
  • Start empirical intravenous antibiotics within an hour of arrival when febrile neutropenia is possible.
  • Take blood cultures first, but do not delay antibiotics for them.
  • Use a validated risk score before considering outpatient management.

Why it matters

Delay to the first antibiotic dose is one of the few modifiable drivers of death in febrile neutropenia.
