Predictors of Outcome and Severity in Adult Filipino Patients with Febrile Neutropenia

Abstract

Aim. The study aimed to describe the profile of Filipino febrile neutropenia patients and to determine parameters associated with severe outcomes.Methods. This is a retrospective study of Filipino febrile neutropenia patients admitted to the Philippine General Hospital. Patients were described in terms of clinical presentation and stratified according to the presence or absence of severe outcomes. Prognostic factors were then identified using regression analysis.Results. 115 febrile episodes in 102 patients were identified. Regression analysis yielded prolonged fever >7 days prior to admission (OR 2.43; 95% CI, 0.77–7.74), isolation of a pathogen on cultures (OR 2.69; 95% CI, 1.04–6.98), and nadir absolute neutrophil count (ANC) < 100 during admission (OR 1.96; 95% CI, 0.75–5.12) as significant predictors of poor outcome. Factors that significantly correlated with better outcome were granulocyte colony-stimulating factor (G-CSF) use (OR 0.31; 95% CI, 0.11–0.85) and completeness of antibiotic therapy (OR 0.26; 95% CI, 0.10–0.67).Conclusion. Prolonged fever >7 days prior to admission, positive pathogen on cultures, and nadir ANC < 100 during admission predicted severe outcomes, whereas G-CSF use and complete antibiotic therapy were associated with better outcomes. These prognostic variables might be useful in identifying patients that need more intensive treatment and monitoring.
