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:

本研究的数据管理由北京医院临床研究机构统一负责。临床资料通过北京医 院临床研究系统录入和管理,AI-FFR的训练与验证在中国科学院大学高性能计算中心私有云平台进行。冠脉造影图像由导管室造影机直接以DICOM格式输出,导丝FFR数值由压力分析仪自动记录并以XML文件导出,所有 XCA图像(血管造影)均以医学数字成像与通信(DICOM)格式存储和传输,用于进一步分析。XCA图像通常包含患者姓名、检查日期、图像模式和设备型号等元数据,为保护隐私,除帧序列外,删除其余元数据。数据质控包括二次录入与一致性比对,对10%随机病例进行双人录入核查,差异率≤0.5%为合格;源数据核查由质控员每月抽查10%病例,核对导管室记录、实验室报告与EDC一致性;影像质控由两名高年资介入医师盲法重标狭窄帧,κ≥0.8视为合格。所有数据均存放于加密服务器,实行权限分级与操作日志记录,确保数据安全、完整与可追溯。

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

Data management is centrally handled by the Clinical Research Organization of Beijing Hospital. Clinical data are entered and managed through the hospital’s clinical research system; AI-FFR training and validation are performed on the private cloud platform of the High-Performance Computing Center, University of Chinese Academy of Sciences. Coronary angiograms are exported in DICOM format directly from the catheterisation-lab angiography units, and wire-based FFR values are automatically recorded by the pressure analyser and exported as XML files. All XCA images are stored and transferred in DICOM format for downstream analysis. These files originally contain metadata including patient name, examination date, modality and device model; for privacy protection, all metadata except the frame sequence are removed. Data-quality control comprises double entry and consistency checks: 10 % of cases are randomly selected for independent dual entry, with a discrepancy rate ≤ 0.5 % considered acceptable. Source-data verification is conducted monthly by quality-control officers who review 10 % of cases against catheterisation-lab records and laboratory reports to ensure EDC consistency. Image quality is verified by two senior interventional physicians who re-label stenosis frames in a blinded manner; an inter-observer κ ≥ 0.8 is required. All data reside on encrypted servers with role-based access and full audit trails to guarantee security, integrity and traceability.
