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:

我们使用病例报告表(CRF)进行数据的采集,使用Epi Info软件进行数据的管理。根据CRF表格的项目采用软件建立本试验专用的数据库系统,数据管理员对病例报告表进行检查及数据同步录入,数据的审核先用采用Epi Info软件中的核查功能,再随机抽取10份病例报告表和数据库中的数据进行人工比较,以确保数据库中的数据与CRF中的结果一致。

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

We use the case report form for data collection, and use Epi Info software for data management. According to the items in the CRF form, the software is used to establish a special database system for this experiment. The data manager checks the case report form and synchronizes data entry and data review. We first adopt the verification function in Epi Info software to review the data, and then randomly select 10 case report forms and data in the database for manual comparison to ensure that the data in the database is consistent with the results in the CRF.
