研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

(1)主要目标:通过机器学习基于入住ICU的重症肺炎患者血液中特征性细胞因子的动态变化轨迹以建立重症肺炎患者不同临床分型,为重症肺炎患者疾病严重程度分层提供依据,并为重症肺炎患者预后的预测提供重要信息。 (2)次要目标:通过检测重症肺炎患者肺泡灌洗液(Bronchoalveolar Lavage Fluid, BALF)中的细胞因子,分析肺泡灌洗液中细胞因子水平(尤其是基线水平)与重症肺炎患者呼吸衰竭严重程度及其他临床结局的相关性。  

Objectives of Study:

(1) Primary Objective: To employ machine learning to establish distinct clinical subtypes of severe pneumonia based on the dynamic trajectory of characteristic cytokines in the blood of ICU-admitted patients. This will provide a foundation for stratifying disease severity in severe pneumonia and offer critical prognostic information for patient outcomes. (2) Secondary Objective: To analyze the correlation between cytokine levels (particularly baseline levels) in bronchoalveolar lavage fluid (BALF) and the severity of respiratory failure or other clinical outcomes in severe pneumonia patients.
