研究目的:

本研究旨在构建并验证基于人工智能的重症急性肾损伤患者连续性肾脏替代治疗撤机时机预测模型。研究将利用MIMIC-IV和eICU大规模公开医疗数据库,通过多种机器学习算法开发能够准确识别CRRT最佳撤机时机的预测模型,为临床决策提供客观量化的评估工具。通过上海交通大学医学院附属仁济医院重症医学科的历史数据进行独立外部验证,评估模型在不同医疗环境中的泛化能力和稳健性,确保模型的临床适用性。同时开展前瞻性观察对照研究,系统比较机器学习模型与临床医师经验判断的预测准确性,验证模型在真实临床场景中的实用价值。最终构建可解释的临床决策支持工具,为临床医师提供标准化、客观化的CRRT撤机决策依据,从而优化医疗资源配置,减少不必要的治疗延续或过早撤机带来的风险,改善重症急性肾损伤患者的临床预后。  

Objectives of Study:

This study aims to develop and validate an artificial intelligence-based prediction model for determining the optimal timing of continuous renal replacement therapy (CRRT) liberation in critically ill patients with acute kidney injury. The research will utilize large-scale public healthcare databases (MIMIC-IV and eICU) to develop prediction models through various machine learning algorithms that can accurately identify the optimal timing for CRRT discontinuation, providing an objective quantitative assessment tool for clinical decision-making. External validation will be conducted using historical data from the Intensive Care Unit of Shanghai Jiao Tong University School of Medicine, Renji Hospital to evaluate the model's generalizability and robustness across different healthcare settings, ensuring clinical applicability. A prospective observational study will systematically compare the predictive accuracy of machine learning models with clinical physician judgment, validating the model's practical value in real clinical scenarios. Ultimately, an interpretable clinical decision support tool will be constructed to provide clinicians with standardized and objective guidance for CRRT weaning decisions, thereby optimizing healthcare resource allocation, reducing risks associated with unnecessary treatment continuation or premature discontinuation, and improving clinical outcomes for critically ill patients with acute kidney injury.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

本研究采用规范化的数据采集和管理系统,包括标准化病例记录表(CRF)和基于互联网的电子数据采集系统(EDC)。回顾性阶段通过标准化数据提取表从MIMIC-IV、eICU数据库和仁济医院病历系统收集数据;前瞻性阶段采用REDCap平台进行实时数据录入。系统具备数据验证、逻辑检查、权限管理等功能。数据质控采用双人独立录入、系统自动检查和定期核查。所有数据去标识化处理,存储于医院安全服务器并设置异地备份。数据访问实行分级权限管理,操作全程可追溯。

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

This study employs a standardized data collection and management system consisting of standardized Case Record Forms (CRF) and internet-based Electronic Data Capture (EDC) systems. The retrospective phase collects data from MIMIC-IV, eICU databases and Renji Hospital medical records through standardized extraction forms; the prospective phase uses REDCap platform for real-time data entry. The system features data validation, logic checks, and permission management. Data quality control includes independent dual entry, automatic system checks, and regular verification. All data undergoes de-identification processing and is stored on secure hospital servers with off-site backup. Data access follows hierarchical permission management with full operation traceability.
