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: |
使用电子数据采集(EDC)系统。电子数据采集(EDC)系统的逻辑核查程序将对录入的数据进行完整性和逻辑检查,并对可能存在问题的数据发出质疑。研究者或数据录入人员可以对数据进行更正,或通过答复质疑进行解释和确认。监查员,数据管理员,以及医学审核人员也会对 eCRF 数据进行审核,并在必要时对有疑问的数据发出质疑。研究者应当及时回复来自系统以及数据审核人员发出的质疑,必要时可能多次发出质疑直至数据问题解决。数据库锁定之前研究团队需要完成数据清理,并汇总试验进行中出现的所有方案偏离的事件,并召开数据审核会议确定分析人群。数据审核会议中所作的决定都需用文件记录。数据审核会议通过后,经研究团队确认对EDC系统中的研究数据库进行锁定,锁定后数据不可再做改动。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Use the Electronic Data Acquisition (EDC) system. The logic verification program of the Electronic Data Acquisition (EDC) system will conduct integrity and logical checks on the entered data and raise questions about data that may have problems. Researchers or data entry personnel can correct the data or explain and confirm it by responding to inquiries. Monitors, data administrators, and medical reviewers will also review eCRF data and raise questions about questionable data when necessary. Researchers should promptly respond to inquiries raised by the system and data reviewers. If necessary, they may raise inquiries multiple times until the data issue is resolved. Before the database is locked, the research team needs to complete the data cleaning, summarize all the events of scheme deviation that occurred during the trial, and hold a data review meeting to determine the analysis population. All decisions made in the data review meeting must be recorded in documents. After the data review meeting was approved, the research team confirmed that the research database in the EDC system would be locked. Once locked, the data could no longer be modified. |
