Objective:

analyze the epidemiological, clinical and bacteriological characteristics that influence the survival of patients with haematological malignancies who developed febrile neutropenia after chemotherapy.

Materials and methods:

cross-sectional study of adult patients diagnosed with hema-tologic malignancies who presented febrile neutropenia during hospitalization in 2014 at Oncólogos de Occidente in Pereira, Manizales and Armenia (Colombia). Univariate and multivariate analyzes were performed. The survival analysis was established according to the Kaplan-Meier method. A value of p<0.05 was established for it. The STATA software was used. This study was endorsed by the bioethics committee of the Universidad Tecnológica de Pereira.

Results:

55 patients were included. The median age was 48 years (31-63), 27 (49%) were men. The most frequent oncological diagnoses were non-Hodgkin's lymphoma (29 %), acute myeloid leukemia (24 %) and acute lymphoblastic leukemia (20 %). The highest lethality occurred on days 21, 32 and 48. Overall mortality was 9 %, mortality due to deep neutro-penia was 18 %.

Conclusion:

the number of febrile neutropenia, longer duration of febrile neutropenia, Charlson index and the history of admission to the ICU are risk factors for mortality, while the use of piperacillin-tazobactam and the increase in the score of the MASCC index are protective factors.
