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:

研究者根据受试者的原始观察记录,将数据及时、完整、正确、清晰地载入病例报告表,录入采用相应的数据库系统双人双机录入,之后对数据库进行两遍比对,电子数据文件分类保存,并有多个备份保存于不同磁盘或记录介质上,妥善保存,防止破坏。

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

According to the original observation records of the subjects, the researchers loaded the data into the case report form in a timely, complete, correct and clear manner, and input the data into the corresponding database system with two persons and two computers. After that, the database was compared twice, and the electronic data files were classified and saved, and multiple backups were saved on different disks or recording media, which were properly preserved to prevent damage.
