Earlier this year, the Infectious Diseases Society of America (IDSA) and the Pediatric Infectious Disease Society (PIDS) released a 2026 update for their guideline, Management of Community-Acquired Pneumonia in Infants and Children Older Than 3 Months of Age, which addresses the diagnosis and management of pediatric patients who have pneumonia with parapneumonic effusion. The 2026 guideline replaces the previous 2011 guideline.
The 2011 guideline featured more than 90 recommendations, spanning from diagnostic testing through discharge criteria. The 2026 guideline is more focused, featuring five key sections (outlined in the table, below) and six recommendations.
Today, we are looking at how recommendations from the 2011 guideline compare to the latest guideline from IDSA and PIDS on the management of community-acquired pneumonia in infants and children older than three months old.

Comparison of Recommendations: 2026 vs. 2011
The following table reflects the new recommendations added in the 2026 update, alongside one that remained unchanged. To view the complete 2026 and 2011 guidelines, along with the complete recommendations themselves, view the full-text versions using the links featured above.
| Item | 2026 | 2011 |
|---|---|---|
| Chest Ultrasound in Children with Parapneumonic Effusion | In children with radiographic evidence of a moderate to large parapneumonic effusion, the panel suggests obtaining a chest ultrasound over computed tomography (CT) or magnetic resonance imaging (MRI) to characterize the size and complexity of the effusion. | History and physical examination may be suggestive of parapneumonic effusion in children suspected of having CAP, but chest radiography should be used to confirm the presence of pleural fluid. If the chest radiograph is not conclusive, then further imaging with chest ultrasound or computed tomography (CT) is recommended. |
| Use of Pleural Fluid Drainage versus Observation | In children with small, uncomplicated parapneumonic effusions, the Infectious Diseases Society of America (IDSA) panel suggests observation over pleural drainage. In children with moderate parapneumonic effusions associated with respiratory distress, large parapneumonic effusions, or documented purulent effusions, the panel recommends pleural drainage (no new evidence) [2011 IDSA CAP guideline]. | The size of the effusion is an important factor that determines management. The child’s degree of respiratory compromise is an important factor that determines management of parapneumonic effusions. Small, uncomplicated parapneumonic effusions should not routinely be drained and can be treated with antibiotic therapy alone. Moderate parapneumonic effusions associated with respiratory distress, large parapneumonic effusions, or documented purulent effusions should be drained. |
| Use of Pleural Fluid Drainage Compared to Surgical Debridement | In children and adolescents (3 months to 18 years) with pneumonia-associated empyema in whom pleural drainage is indicated, the panel suggests using chest tube drainage and intrapleural fibrinolytics rather than surgical debridement as first-line therapy in most cases. | Both chest thoracostomy tube drainage with the addition of fibrinolytic agents and VATS have been demonstrated to be effective methods of treatment. The choice of drainage procedure depends on local expertise. Both of these methods are associated with decreased morbidity compared with chest tube drainage alone. However, in patients with moderate-to-large effusions that are free flowing (no loculations), placement of a chest tube without fibrinolytic agents is a reasonable first option. VATS should be performed when there is persistence of moderate-large effusions and ongoing respiratory compromise despite ∼2–3 days of management with a chest tube and completion of fibrinolytic therapy. Open chest débridement with decortication represents another option for management of these children but is associated with higher morbidity rates. |
| Choice of Chest Tube Size | In children (3 months to 18 years) with parapneumonic effusion or empyema that necessitates drainage, the panel members suggest the use of small-bore (≤12 French [Fr]) chest tubes over large-bore (≥14Fr) tubes. | Not addressed. |
| Use of tPa and DNase or tPa Alone for Fibrinolysis | In children (3 months to 18 years of age) with pneumonia-associated empyema, the panel suggests administering tPA alone over tPA and DNase. | Not addressed. |
