Febrile Infants and Children • Fever is Very Common • Emergency Departments • Outpatient Clinics • Appropriate Management of Fever • Has Changed Over Last Few Decades • Is Debated • Differs Among Physicians
Serious Bacterial Infections (SBI) • Bacteremia • Meningitis • Urinary Tract Infection (UTI) • Bacterial Diarrhea • Pneumonia • Bone & Joint Infections

Disadvantages to Hospitalization • Nosocomial Infections • Adverse Effects of Antibiotics • Emergence of Resistant Bacteria • Stresses on Families • Cost
Rochester, Boston, & Philadelphia Criteria Criteria established to predict infants <3 months at low risk for SBI. A = Rochester B = Boston C = Philadelphia

Management of febrile InfantsOffice Setting • Prospective study of 3066 febrile infants ≤3 months seen by practitioners from the Pediatric Research in Office Setting (PROS) Network. • Current guidelines followed in 42% • Only 2/63 with bacteremia or meningitis were not initially treated with antibiotics. Both well after treatment. Clinicians use individualized judgment in treating febrile infants. Using clinical guidelines would not have improved care, but would have resulted in more hospitalizations and labs. Pantell RH, et al. (PROS Study). JAMA. 2004.
Special Patient Populations • Neonates • Transplant recipients • Bone marrow • Solid organ • Oncology patients • Undergoing therapy, mucositis, central line • Most chemotherapy: nadir ~ 10 days after rx • Asplenic patients, including sickle cell
Treatment for neonates ≤ 2 months • If < 28 days old • Ampicillin AND cefotaxime OR • Ampicillin AND gentamicin • Consider acyclovir • If 29-60 days old • Ceftriaxone ± Ampicillin OR Vancomycin • Until CSF results are known (cell count, protein, glucose), initiate therapy with meningitic dosing regimen
The prevalence of urinary tract infections in febrile children ≤24 months is closest to A) 2-4% B) 6-8% C) 10-12% D) 14-16% E) 18-20%
The prevalence of urinary tract infections in febrile uncircumcised males <3 months is closest to A) 2-4% B) 6-8% C) 10-12% D) 14-16% E) 18-20%
UTI Prevalence • Meta-Analysis (18 Articles; 22,919 Children) • UTI Prevalence in Febrile Children ≤24 Months 7% Shaikh N, et al. Pediatr Infect Dis J. 2008.
UTI Prevalence • UTI Prevalence in Male Infants <3 months 2.4% 20% Shaikh N, et al. Pediatr Infect Dis J. 2008.
UTI Prevalence • Prevalence By Age (%) • Prevalence Highlights • Decreases with Age • Highest in Females < 1 Year • Highest in Uncircumcised Males < 3 Months Shaikh N, et al. Pediatr Infect Dis J. 2008.

Retrospective study of 354 children <2 years discharged with diagnosis of UTI to characterize patients with bactermia or meningitis. • Bacteremia in 9% (33/354) • Limited to age <6 months • Inversely related to age • 0-1 Month = 21% 1-2 Months = 13% 2-3 Months = 4% • Meningitis in 1% (4/354) • Limited to age <1 month Bachur R, et al. Pediatr Emerg Care. 1995.

Bronchiolitis & Serious Bacterial Infection (SBI)Emergency Departments • Multicenter prospective study of 1248 febrile infants ≤ 60 days to evaluate frequency of SBI in infants with and without RSV infection. Total Infants (n=1248) SBI in 11.4% RSV Pos (n=269) RSV Neg (n=979) SBI in 12.5% UTI in 10.1% Bacteremia in 2.3% Bacterial Meningitis in 0.9% SBI in 7% UTI in 5.4% Bacteremia in 1.1% Bacterial Meningitis in 0% Levine DA, et al. Pediatrics. 2004.
Bronchiolitis & Serious Bacterial Infection (SBI)Primary Care Offices • Prospective cohort study of 3066 febrile infants <3 months to evaluate frequency of SBI in infants with and without clinically diagnosed bronchiolitis. • Infants with bronchiolitis, SBI in 0%. • Infants without bronchiolitis, SBI in 8%. In office setting, SBI is uncommon in febrile infants <3 months with clinically diagnosed bronchiolitis. Luginbuhl LM, et al. Pediatrics. 2008.
Conclusion • To identify febrile infants and children at risk of serious bacterial infections, clinicians should use a combination of • Clinical Judgement • Published Guidelines • Clinical and Laboratory Indices • Immunization status
