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:

研究者填写电子病例报告表 1.电子病例报告表中所有数据均应与受试者原始病历数据核对,保证无误。 2.电子病例报告表作为原始数据记录,并由研究者签名且标注日期。 3.对显著偏高或在临床接受范围以外的数据,由研究者作临床意义判断。 4.详细内容请参照电子病例报告表填写说明。 数据库锁定 在数据审核并确认建立的数据库正确后,由数据管理人员、主要研究者、统计分析人员、申办者和监查管理人员共同对数据进行审核,并完成分析人群 的最后定义及判断,之后由数据管理员对数据库进行锁定。 锁定后的数据库或文件一般情况下不得再做改动。

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

Completion of Electronic Case Report Form (eCRF) 1.All data entered into the electronic case report form (eCRF) shall be verified against the source medical records of the subject to ensure accuracy and completeness. 2.The eCRF shall serve as a source document, and must be signed and dated by the investigator. 3.Any markedly abnormal values or results outside the clinically acceptable range shall be reviewed and interpreted by the investigator in terms of their clinical significance. 4.For detailed instructions, please refer to the eCRF completion guidelines. Database Lock After data review and confirmation that the database has been properly established, the database shall be jointly reviewed by the data management team, principal investigator, statisticians, sponsor, and monitoring personnel. The final definition and determination of the analysis populations shall then be completed. Subsequently, the database shall be locked by the data manager.In general, no further modifications shall be made to the locked database or related files.
