Neutropenia is usually defined as an absolute neutrophil count below 0.5 × 10⁹/L or a predicted fall below that level. Fever is a single temperature of 38°C or higher, or 37.8°C sustained. Chills, hypotension, breathlessness, confusion or mucosal symptoms may signal sepsis. Patients should have a written action plan.
Urgent blood cultures, full blood count, renal and liver function, and focused imaging are obtained. Empirical broad-spectrum antibiotics are started promptly, with adjustment based on cultures and clinical course. Growth factors and antifungal therapy are used in selected cases. Source control and fluid resuscitation are important in sepsis.
