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、清晰地载入原始数据。录入采用相应的数据库系统双人双机录入。原始测量数据在按要求完成数据录入和核查后,按编号的顺序归档保存,并填有检索目录等,并扫描留底,以备查考。原始数据的电子录入文件为避免遗失损坏,进行多个备份,保存于不同U 盘中。

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

Investigators transcribe subjects' source observations into source data promptly, completely, accurately, and legibly. Data entry is performed via dual independent entry using separate database systems. After verification, original measurements are archived sequentially by ID number with retrieval indices, and scanned for backup. Electronically captured source data is preserved in multiple encrypted backups stored on physically separated USB drives to prevent loss or damage.
