Abstract
Background:Despite the 2001 standardized interpretation criteria established by the World Health Organization, the radiological identification of pneumonia in childrenremains challenging, with significant inter-observer variability persisting.Objectives: To describe the epidemiological and clinical characteristics of community-acquired pneumonia in children and to evaluate inter-observer radiological agreement in the diagnosis of pneumonia in children under five years of age. Materials andMethods: A descriptive, observational study involving452 patientshospitalized in a pediatric referral centerbetween October 2010 and September 2013. Clinical and sociodemographic variables were evaluated. Two independent radiologists evaluated the images according to the World Health Organization’s standardization of interpretation of chest radiographs for the diagnosis of pneumonia in children, modified to take not only consolidation, alveolar infiltrate and pleural effusion into consideration, but also interstitial infiltrate.Results: Around 70% of the children were under two years of ageand family income was one minimum salary or less in half the households. Pneumonia was classified as severe or very severe in 83.9% and complicated in 22.6%. The deathrate was 1.5%. Inter-observer agreement was almost perfectfor pleural effusion (kappa 0.825). Consolidation was the most common finding (66.8%),with inter-observer agreement considered substantial (kappa 0.696). Conversely, agreement was poor for interstitial or alveolar infiltrate (kappa 0.533). Conclusion: Agreement was high for the radiographicfinding of pleural effusion; however, interstitial and alveolar infiltrates proved difficult to interpret. Consolidation was the most common abnormality in hospitalized children with severe pneumonia.
