Abstract

AbstractAimTo describe the characteristics of febrile oncology patients seen in the Paediatric Emergency Department and microbiological characteristics of the invasive bacterial infections (IBIs) diagnosed.MethodsWe conducted a prospective observational study of febrile oncology patients seen between 2016 and 2022. We divided haematologic cancers by the aggressiveness of the chemotherapy received at the time.ResultsWe included 418 episodes (272 haematologic cancers, 146 solid tumours). The median duration of fever was 2 h (interquartile range: 1–3) and 97.6% of patients were well‐appearing on arrival. We diagnosed 61 IBIs (14.6%), including six episodes of bacterial sepsis. One other episode was coded as sepsis without microbiological confirmation, yielding seven episodes overall (1.7%). Rates of IBI and sepsis were higher among patients with high‐risk haematologic cancers than those with low‐risk haematologic cancers or solid tumours (22.9%, 5.4% and 10.3%, p < 0.01; 3.4%, 0% and 0.7%, p = 0.06, respectively). Leading causes were S. epidermidis (42.6%) and E. coli (14.7%). Gram‐positive bacteria caused 67.2% of non‐septic IBIs and 50% of septic episodes.ConclusionMost febrile oncology patients are well‐appearing and present with a very short history of fever. Prevalence of IBI and sepsis and the main disease‐causing bacteria differ by cancer type and the presence of sepsis.
