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: |
研究数据采用标准化病例报告表(Case Report Form,CRF)进行采集,包括患者基本信息、疾病严重程度评分、股四头肌超声测量结果、治疗信息及临床结局等内容。所有数据由经过培训的研究人员录入电子数据库并进行双人核查。研究数据采用唯一编码进行去标识化处理,存储于医院授权计算机及受密码保护的电子数据库中,仅研究团队成员可访问。研究结束后数据保存不少于5年。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data will be collected using standardized CRFs and entered into a secure electronic database. Data accuracy will be verified by trained investigators. All participant information will be de-identified and stored securely with access restricted to authorized study personnel. |
