Management of Community-Acquired Pneumonia in Children

Outpatient Management

The Infectious Diseases Society of America recommends high-dose oral amoxicillin (90 mg/kg/day in 2 doses, maximum 4 g/day) as the first-line treatment for presumed bacterial pneumonia in the outpatient setting, with consideration of adding a macrolide if atypical pneumonia is suspected 1, 2
Determine severity based on clinical presentation, respiratory status, and ability to maintain oral intake 3
Assess vaccination status for Haemophilus influenzae type b and Streptococcus pneumoniae, as this affects antibiotic selection 1, 2
Consider local patterns of antimicrobial resistance in your community 4, 3

Respiratory distress, hypoxemia, inability to maintain oral hydration, or failed outpatient therapy are indications for hospitalization 3, 5
Complicated pneumonia (empyema, large pleural effusion) requires hospitalization 3, 5
For fully immunized children with minimal local penicillin resistance, the first-line treatment is ampicillin or penicillin G 1, 2
For not fully immunized children or areas with significant penicillin resistance, the first-line treatment is ceftriaxone (50-100 mg/kg/day) or cefotaxime (150 mg/kg/day) 1, 2

Add vancomycin or clindamycin to β-lactam therapy if clinical, laboratory, or imaging characteristics suggest Staphylococcus aureus infection 3, 5
For MRSA, vancomycin (40-60 mg/kg/day) or clindamycin (if susceptible) is recommended 3, 5
Add oseltamivir if influenza is suspected or confirmed, and continue appropriate antibacterial coverage for secondary bacterial pneumonia 1, 2

Clinical improvement should be expected within 48-72 hours of starting appropriate therapy 3
Consider alternative diagnoses or resistant organisms if no improvement occurs 3, 5
Routine follow-up chest radiographs are not necessary for patients who recover uneventfully 3
