Utility of sepsis evaluation in infants 90 days of age or younger with fever and clinical bronchiolitis.
OBJECTIVE
To identify the clinical utility of obtaining blood, urine and cerebrospinal fluid for bacterial culture among febrile infants <90 days of age with clinical bronchiolitis.


METHODS
Retrospective chart review from 1995 to 2000.


METHODS
Urban emergency department of a tertiary children's hospital.


METHODS
All infants <90 days of age presenting with fever and clinical bronchiolitis.


METHODS
Result of the cultures of blood, urine and cerebrospinal fluid.


RESULTS
Of 3051 (11%) febrile infants, 329 met criteria for clinical bronchiolitis. Blood for culture was obtained from 309 (94%), urine for culture was obtained from 273 (83%) and cerebrospinal fluid for culture was obtained from 200 (61%). One hundred eighty-seven (57%) infants had all 3 specimens sent for culture. No cases of bacteremia [0%; 95% confidence interval (CI), 0, 1.1%] or meningitis (0%; 95% CI 0, 1.8%) occurred among these infants. However, 6 infants (2%; 95% CI 0.8, 5.7%), all male, had a culture of urine consistent with infection (4 Escherichia coli, 1 Staphylococcus aureus, 1 viridans streptococci).


CONCLUSIONS
The risk of bacteremia or meningitis among infants <90 days with fever and bronchiolitis is low in this age group. The risk of urinary tract infection in this age group is also low, but not negligible, at 2%.
