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:

5.数据管理 5.1数据采集方式 本项目采用电子病历系统(Electronic Medical Record System, EMRS)进行数据采集。并利用专门的数据抽取工具,从EMRS中提取研究所需的患者信息和相关的医疗数据。 5.2数据库访问权限,访问数据库权限分为三个级别: (1)管理员权限:可以访问所有数据,负责维护和管理数据库,处理系统故障。 (2)研究员权限:仅可访问与其研究相关的数据,不能进行数据修改或删除。 (3)数据录入员权限:只能录入和修改数据,不能删除数据。 5.3操作痕迹保留 是的,系统采用了高级的审计跟踪功能,可以跟踪并记录每个用户的所有操作,确保数据的完整性和透明度。 5.4电子病例报告表 (eCRF) 的建立 根据研究方案,我们已经建立了专门的eCRF,用于详细、系统地记录研究数据。 5.5数据管理过程 (1)录入:数据录入员根据原始医疗记录和其他相关文档,录入数据到eCRF中。 (2)锁定:每月数据录入完成后,由项目负责人或数据管理负责人进行数据审核。确保数据准确无误后,数据会被锁定,以防止进一步修改。 (3)导出:数据导出由项目负责人操作,数据将导出为DICOM格式,并且通过文件命名给病人的病情进行标注,以供后续分析。 (4)储存:所有数据存储在加密的、有冗余备份的服务器上。同时,每季度会进行一次完整的数据备份,备份数据保存在安全的物理存储设备中。

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

5. Data management 5.1 Data collection method This project uses the Electronic Medical Record System (EMRS) for data collection. And use specialized data extraction tools to extract patient information and related medical data required for the study from EMRS. 5.2 Database access permissions, which are divided into three levels: (1) Administrator privileges: Can access all data, responsible for maintaining and managing databases, and handling system failures. (2) Researcher permissions: Only access to data related to their research is allowed, and data modification or deletion cannot be performed. (3) Data entry personnel permissions: can only enter and modify data, cannot delete data. 5.3 Retention of Operation Traces Yes, the system adopts advanced audit tracking function, which can track and record all operations of each user, ensuring data integrity and transparency. 5.4 Establishment of Electronic Case Report Form (eCRF) According to the research plan, we have established a dedicated eCRF for detailed and systematic recording of research data. 5.5 Data Management Process (1) Input: The data entry personnel input the data into eCRF based on the original medical records and other relevant documents. (2) Locking: After monthly data entry is completed, the project leader or data management manager will conduct data review. After ensuring the accuracy of the data, it will be locked to prevent further modifications. (3) Export: The data export is operated by the project leader. The data will be exported in DICOM format and labeled with the patient's condition through file naming for subsequent analysis. (4) Storage: All data is stored on encrypted servers with redundant backups. At the same time, a complete data backup will be conducted every quarter, and the backup data will be saved in a secure physical storage device.
