Neutropenic sepsis

Headline
Etiology Suspect when neutrophils < 0.5 x 109

Use MASCC score to risk stratify
Epidemiology
Clinical presentation fever >38C >1h (lack of fever DOES NOT rule out)
Pathogenesis
Diagnostic investigations peripheral + central blood cultures.
➥ blood/urine cultures, nasal swab for extended viral screen, routine bloods
➥ CXR. Avoid DRE but examine perineum
➥ High-res chest CT most sensitive for fungal infections; exclude TB
Management Acute management: as with sepsis. Empirical abx within 60 min (patients should have a personalised plan) +/- gram positive cover (e.g. vancomycin); G-CSF not routine
➥ G-CSF if expected neutropenia >10 days
➥ Daily Tº + baseline bloods until apyrexial + neutrophils > 0.5x109
➥ Persistent fever after resolution of neutropenia: untreated infection (avascular site? abx coverage?); immune reconstitution; drug reaction and other non-infective causes

Prevention: Source control! (Hand hygiene, environmental cleaning, food (cooked+pasteurised, no peppers/strawberries/flowers), water management (v hot or v cold), air management = HEPA filtered
