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: |
1. 数据收集 通过知情同意书明确告知参与者数据用途、存储期限及撤回权利。本研究仅收集与研究相关的临床数据,并通过ID编码替代姓名,ID编码表(ID对应的姓名、身份证号及电话)由项目负责人在合规云平台上加密保管。 2. 数据存储 电子数据加密存储于合规第三方云平台;纸质文件锁柜保存,通过访问日志记录访问人员姓名及访问日期。 3. 数据访问权限控制 对数据访问权限进行分级,仅项目负责人有权访问ID编码表;其余研究者仅可访问自己责任部分的数据。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1. Data Collection Participants will be clearly informed, through the informed consent form, about the purpose of data use, storage duration, and their right to withdraw. Only research-related clinical data will be collected. Personal identifiers will be replaced with ID codes, and the ID linkage table (containing names, ID numbers, and phone numbers) will be encrypted and stored on a compliant cloud platform by the principal investigator. 2. Data Storage Electronic data will be encrypted and stored on a compliant third-party cloud platform. Paper documents will be kept in locked cabinets, and access logs will record the names of personnel and dates of access. 3. Access Control Data access permissions will be tiered. Only the principal investigator will have access to the ID linkage table, while other researchers may access only the data corresponding to their assigned responsibilities. |
