Abstract

BACKGROUND:

The objective of this study was to determine whether vomiting at presentation of a febrile illness in immunocompromised children with central venous catheters (CVCs) predicts bacteremia.

METHODS:

A chart review was conducted of children who were admitted to the hospital with a diagnosis of cancer or aplastic anemia, fever, and a CVC. Data were collected on the presence or absence of vomiting, catheter type, presence or absence of severe neutropenia, C‐reactive protein (Crp) value, and culture results.

RESULTS:

There were 143 admissions for fever among 48 children. Among 35 admissions with emesis, 19 included bacteremia; whereas, among 107 admissions without emesis, 19 included bacteremia (P < .001). There was a 5‐fold greater risk of bacteremia in children with children without vomiting (odds ratio, 5.50; 95% confidence interval, 2.20‐13.67). Gram‐negative organisms were more likely to be associated with vomiting than Gram‐positive organisms (P = .008). Children with severe neutropenia did not have a significantly higher rate of bacteremia than children who had neutrophil counts >500 cells/mm^3^. Other factors that were associated with higher rates of bacteremia were underlying diagnosis and catheter type.

CONCLUSIONS:

Immunocompromised children with a CVC and a fever who presented with vomiting were more likely to have bacteremia than similar children who presented without vomiting. Gram‐negative organisms were more likely to be associated with emesis than Gram‐positive organisms. The absence of severe neutropenia was not associated with a decreased likelihood of bacteremia. These findings may be useful in identifying children who are at high risk for bacteremia and in determining initial, empiric therapy. Cancer 2009. © 2009 American Cancer Society.
