##plugins.themes.vojs.article.main##
Abstract
Objectives: This study aimed to describe the clinical and laboratory characteristics and to identify factors associated with severe pneumonia in pediatric patients hospitalized at Saint Paul Hospital.
Subjects and Methods: A cross-sectional descriptive study was conducted on 1,200 children under 16 years of age diagnosed with pneumonia between June 2024 and June 2025. Data were collected from medical records, including demographic features, clinical manifestations, blood test results, and chest X-ray findings.
Results: Pneumonia was most common in children under 2 years of age (76.6%), with the predominant symptoms being cough (98.7%), fever (65.2%), and pulmonary rales (96.1%). The proportion of severe pneumonia tended to decrease with age. Multivariate logistic regression analysis identified three independent risk factors for severe pneumonia: age < 1 year, low birth weight, and anemia.
Conclusion: These findings provide practical evidence for early screening, prognosis, and management of severe pneumonia in children in Hanoi.
