Abstract: Severe pneumonia in children remains a leading cause of mortality globally，and its prognostic evaluation is a critical and challenging aspect of clinical management. This review explores the pivotal factors influencing the prognosis of children with severe pneumonia， including pathogen characteristics，host immune response，the occurrence of complications，and the adequacy of initial therapeutic interventions. Prognostic assessment should extend beyond traditional survival rate metrics，and it is advocated to the establish a comprehensive evaluation framework encompassing acute disease management，organ function recovery，and prevention and management of complications，and an emphasis should be placed on long-term quality of life. This article explores the application value and limitations of clinical symptoms and signs，imaging modalities，serum biomarkers，and pulmonary function tests in predicting outcomes of severe pneumonia，in order to achieve. The transitioning of therapeutic goals from infection control to lung functional recovery.
