Antibiotic Use in Pediatric Patients with Fever and Cough

Introduction to Antibiotic Stewardship

The American Academy of Pediatrics emphasizes that upper respiratory infections are predominantly viral and require no antibiotics, and inappropriate antibiotic prescribing for viral URIs is explicitly discouraged due to adverse events, resistance development, and unnecessary costs 4

For community-acquired pneumonia, look for focal findings on exam, tachypnea, hypoxia, or respiratory distress, and if present, chest radiography is indicated, as recommended by the American Academy of Pediatrics 5
For protracted bacterial bronchitis, assess for chronic wet/productive cough without other explanation, which requires specific cough characteristics, not just fever, according to the American Thoracic Society 7, 8
For acute bacterial sinusitis, requires either persistent symptoms >10 days without improvement, severe onset with high fever and purulent nasal discharge for 3-4 consecutive days, or worsening symptoms after initial improvement, as stated by the American Academy of Pediatrics 4

First-line treatment for children <5 years with bacterial pneumonia is oral amoxicillin 90 mg/kg/day divided twice daily, which covers Streptococcus pneumoniae, the predominant pathogen, as recommended by the American Academy of Pediatrics 5
First-line treatment for children ≥5 years with bacterial pneumonia is oral amoxicillin 90 mg/kg/day (max 4g/day) in 2 doses, with consideration of adding a macrolide only if atypical pathogens are suspected, according to the American Academy of Pediatrics 5, 9
Treatment duration for uncomplicated bacterial pneumonia is 5-7 days, as stated by the American Academy of Pediatrics 5
First-line therapy for protracted bacterial bronchitis is oral amoxicillin-clavulanate for 2 weeks initially, which targets Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae, as recommended by the American Thoracic Society 7, 8

Do not prescribe antibiotics to "treat" fever alone, as fever requires investigation of the root cause before starting treatment, and unremarkable labs suggest this is not a serious bacterial infection requiring immediate empiric therapy, as stated by the American Academy of Pediatrics 4
Avoid broad-spectrum agents without specific indication, as broad-spectrum antibiotics should be reserved for documented serious infections with identified pathogens showing resistance, or for critically ill patients where time to effective therapy impacts mortality, according to the American Academy of Pediatrics 2, 3
Do not use antibiotics for likely viral illness, as many as 10 million antibiotic prescriptions annually in the U.S. are directed toward respiratory conditions unlikely to benefit, which contributes to resistance and causes avoidable adverse events, as reported by the American Academy of Pediatrics 4

Broad-spectrum antibiotics are indicated only in specific high-risk scenarios, such as clinically unstable patients, those with hypotension, severe respiratory distress, or multiorgan dysfunction, which require escalation to cover resistant Gram-negative, Gram-positive, and anaerobic bacteria, as recommended by the American Society of Clinical Oncology 2, 3
Documented neutropenia with fever requires empiric broad-spectrum coverage, but this requires absolute neutrophil count documentation, according to the American Society of Clinical Oncology 1, 2, 3
Hospital-acquired or post-surgical pneumonia requires broader coverage for aerobic Gram-negative rods, as stated by the British Thoracic Society 10
