Chest Radiograph Utilization Among Children Treated for Pneumonia in a Primary Care Network.

Area of Science:

• Pediatric Medicine
• Pulmonology
• Diagnostic Imaging

Background:

• Pneumonia is a common childhood illness.
• The role of chest X-rays (CXRs) in diagnosing and managing pediatric pneumonia in primary care is not well-defined.
• Variability in CXR utilization exists across different clinical settings.

Purpose of the Study:

• To assess the frequency of CXR utilization in children diagnosed with pneumonia in primary care.
• To determine if CXR use is associated with differences in antibiotic treatment and patient outcomes.
• To evaluate the impact of CXR on treatment failure in pediatric pneumonia.

Main Methods:

• Retrospective cohort study involving 29,528 children with pneumonia across 77 pediatric practices.
• Multivariable logistic regression analysis was employed.
• Evaluated associations between CXR performance and outcomes like clinic revisit, antibiotic changes, and composite treatment failure, adjusting for illness severity.

Main Results:

• Only 10.1% of children diagnosed with pneumonia underwent a CXR.
• Significant practice-level variation in CXR utilization was observed (range 0%-75%).
• No significant difference in the composite outcome of treatment failure was found between children who had a CXR and those who did not (aOR 1.06; 95% CI [0.68, 1.65]).

Conclusions:

• CXR is underutilized in the primary care management of pediatric pneumonia.
• CXR performance in children with pneumonia did not appear to influence treatment outcomes or failure rates.
• Further research may be needed to clarify the optimal role of CXR in primary care settings for pediatric pneumonia.
