【摘要】 儿童重症肺炎的评估模型以临床特征为核心，结合实验室与影像学指标，形成多维度预警体系。不同预测模型有其临床应用背景、优势及局限性，科学使用可显著提高早期识别率，优化分级诊疗路径，降低重症肺炎患儿病死率。未来需进一步验证和简化模型，推动其在基层医疗的普及。更多还原

【Abstract】 The assessment models for severe pediatric pneumonia are centered on clinical features,and integrated with laboratory and imaging indicators to form a multidimensional early warning system.Different predictive models have specific clinical contexts,strengths,and limitations.When applied appropriately,they can significantly enhance early detection,optimize hierarchical diagnosis and treatment pathways,and reduce mortality of children with severe pneumonia. Future efforts should focus on further validation and simplification of these models to promote their widespread application in primary healthcare settings.更多还原
