Abstract
Febrile neutropenia in pediatric oncology patients may lead to severe infection, with adverse events including septic shock or death. The aim of the study was to investigate the prevalence of severe adverse outcomes and to determine the associated risk factors. This is a retrospective cohort study of pediatric oncology patients with febrile neutropenia from October 2013 to September 2017 at Thammasat University Hospital, Thailand. Clinical assessment and time-to-event of severe outcomes were analyzed. There were 95 febrile neutropenic episodes; severe adverse outcomes were documented in 11 (11.5%), with no infection-associated mortalities. Those with severe outcomes were older, received prophylactic granulocyte-colony stimulating factor (G-CSF), and had documented infection, lower initial ANC, and central venous catheter insertion. The proportional hazard regression model revealed age ≥ 10 years (hazard ratio [HR], 5.96; p = 0.005), prophylactic G-CSF (HR, 4.52; p = 0.028), and microbiologically documented infections (HR, 12.53; p = 0.017) independently predicted severe adverse outcomes. Although severe adverse outcomes occurred in only 11.5% of our febrile neutropenic episodes, we identified a few risk factors that may help predict those at highest risk.
