Introduction: Febrile neutropenia (FN) is a common complication of immunocompromised patients – whether due to infection, cancer, drug-induced, or other bone marrow failure states. With the incidence of patients with immunocompromised states on the rise, this life threatening complication is also increasing. The importance of initiating the appropriate empiric antibiotic therapy can prove to be lifesaving, thus we examined how the initial choice of antibiotics influenced patient outcomes. This study aims to determine the effect of adherence to guideline-based antimicrobial therapy for adult febrile neutropenia patients in terms of patient outcomes. Methods: This is a 10-year cross-sectional analytical study which was conducted at the Dr. Pablo O. Torre Memorial Hospital (DPOTMH) by doing a retrospective chart review involving adult patients with FN from 2007 to 2016. We determined use of guideline-based antibiotics, examined the factors that influenced adherence, and investigated the effect of initial treatment on patient outcome. Results: Among the 257 adult patients with FN included in the study, Infectious Diseases Society of America (IDSA) guideline-based antibiotics were administered to 65%. On multivariate analysis, the most powerful predictor of adherence to guideline-based antibiotics was the type of risk (p=0.000), with high risk patients thrice more likely to be given guideline-based antibiotics. Other predictors were physician specialty (p=0.036) and hematologic malignancy (p=0.045). This study showed that among low risk patients with FN, a trend towards patient discharge was observed (OR 1.18, CI=0.16–8.63). However overall, adherence to guidelinebased empiric antibiotic in treating adult FN patients did not correlate to patient discharge (p=0.134, OR 0.557, 95% CI=0.260-1.205). Conclusion Our data suggest that adherence to guidelinebased antibiotics in managing adult Filipino patients with febrile neutropenia does not correlate to better outcomes such as patient discharge. Significant factors associated with adherence to guideline-based antibiotics are physician specialty, hematologic malignancy, and type of risk.
