Cohort study 

研究目的:

1. 主要目的:基于ΔPaO?/FiO?和MP的72小时动态变化,识别SA-ARDS患者的两种动态亚表型(氧合-机械能一致型[OM] 与 拮抗型[OA]),并评估不同潮气量轨迹(上调、下调、高维持)与14天脱机成功率、28天无呼吸机天数的关联。 2. 次要目的:1) 通过因果森林模型和亚组分析,探讨疾病严重程度(APACHE II、乳酸)对表型特异性潮气量策略疗效的修饰作用;2) 构建基于亚表型和临床变量的脱机成功预测模型。  

Objectives of Study:

1. Main purpose: Based on the 72-hour dynamic changes of ΔPaO?/FiO? and MP, two dynamic subphenotypes (oxygenation-mechanical energy consistent type [OM] and antagonistic type [OA]) in SA-ARDS patients were identified, and the associations between different tidal volume trajectories (up-regulated, down-regulated, and high maintenance) and the success rate of weaning from the ventilator at 14 days and the number of days without ventilator at 28 days were evaluated. 2. Secondary objectives: 1) To explore the modifying effect of disease severity (APACHE II, lactic acid) on the efficacy of phenotypic specific tidal volume strategies through causal forest models and subgroup analysis; 2) Construct an offline success prediction model based on subphenotypic and clinical variables.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

I. Data Collection MethodsThe data was extracted by using the electronic data acquisition template (Excel/EDC platform) in combination with the electronic medical record backtracking of the First Affiliated Hospital of Baotou Medical College.Collection tools: Customized templates (including data verification function), hospital-authorized electronic medical record query permissions, data extraction record forms, and question tracking forms.Personnel requirements: Two physicians from this department should be trained uniformly before starting work. The Kappa value of the pre-test must be >=0.85 before formal collection can be carried out. ?Ii. Data Collection Process and StandardsScreening: Adult sepsis patients in the hospital ICU from 2018 to 2025 were retrieved according to the inclusion/exclusion criteria. The final cohort was determined through double-person review, and a baseline information table was formed.Extraction and entry: Data were extracted in the order of "baseline → exposure variable → outcome variable → covariate". Two people independently calculated and checked. After checking, the data was manually entered into the template in real time. The date was uniformly set as "YYYY-MM-DD", and categoristic variables were filled in according to the preset options. ?Iii. Requirements for Data Recording1. Completeness: Required fields must not be left blank. If any are missing, the reasons should be noted. Key data missing by more than 20% will be excluded.2. Accuracy: Strictly based on the original medical records, without subjective modification, and the SOFA score calculation process is traceable.3. Consistency: Double-check by two people, correct any differences and record them. The same indicator remains uniform.4. Traceability: Indicate the data source, collector and time. ?Iv. Data Review ProcessThird-level review (<=50 cases per batch, completed within 3 working days) :Self-inspection: The collection personnel verify the completeness and standardization.Cross-review: Review key indicators within the team and resolve doubts.Final review: The research leader randomly selects 30% of the data for review. After confirmation, the data is locked. ?V. Requirements for Data Transmission and Storage1. Transmission: Internal encrypted network transmission, recording transmission logs, and no transmission through the external network.2. Storage: Stored on the hospital's dedicated server, backed up in Excel and CSV formats. Before storage, privacy information desensitization must be completed. Manual excerpting throughout the process is strictly prohibited from disclosing patients' personal sensitive information. Only the hospitalization number will be retained and stored for five years after the end of the study
