Abstract

Purpose: To compare outcome and cost of ambulatory versus hospitalized management among febrile neutropenic children at low risk for invasive bacterial infection (IBI). Patients and Methods: Children presenting with febrile neutropenia at six hospitals in Santiago, Chile, were categorized as high or low risk for IBI. Low-risk children were randomly assigned after 24 to 36 hours of hospitalization to receive ambulatory or hospitalized treatment and monitored until episode resolution. Outcome and cost were determined for each episode and compared between both groups using predefined definitions and questionnaires. Results: A total of 161 (41%) of 390 febrile neutropenic episodes evaluated from June 2000 to February 2003 were classified as low risk, of which 149 were randomly assigned to ambulatory (n = 78) or hospital-based (n = 71) treatment. In both groups, mean age (ambulatory management, 55 months; hospital-based management, 66 months), sex, and type of cancer were similar. Outcome was favorable in 74 (95%) of 78 ambulatory-treated children and 67 (94%) of 71 hospital-treated children (P = NS). Mean cost of an episode was US $638 (95% CI, $572 to $703) and US $903 (95% CI, $781 to $1,025) for the ambulatory and hospital-based groups, respectively (P = .003). Conclusion: For children with febrile neutropenia at low risk for IBI, ambulatory management is safe and significantly cost saving compared with standard hospitalized therapy. © 2004 by American Society of Clinical Oncology.
