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:

病例报告表应由研究者或指定人员及时填写,以保证内容准确、总结及时。病例报告表一般不应涂改,如确有错误需要修改,应当在修改处签名并记录修改日期。完成的病例报告表由临床监查员审查后,移交数据管理员,进行数据录入与管理工作。 数据录入与管理指定数据管理员负责。为保证数据的准确性,应由两位数据录入员独立进行双录入,录入完成后进行两数据库的比对核查。 对病例报告表中存在的疑问,数据管理员将产生数据疑问表(DQF),并通过临床监查员向研究者发出询问,研究者应尽快解答并返回,数据管理员根据研究者的回答进行资料修改、确认与录入,必要时可以再次发出数据疑问表。所有的疑问表及解答应保存备查。 然后抽查5%的CRF表进行原始数据核对,控制错误率在5%以内。 在数据审核并确认所建的数据库无误后,由主要研究者、申办者、统计分析人员对数据库进行锁定,锁定后的数据文件不再做改动并提交统计分析人员进行数据处理。

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

The case report form should be filled in by the investigator or designated personnel in a timely manner to ensure that the content is accurate and the summary is timely. In general, the case report form should not be altered, and if there is a mistake that needs to be corrected, the amendment should be signed and the date of modification should be recorded. The completed case report form is reviewed by the clinical monitor and handed over to the data administrator for data entry and management. Data entry and management are designated as data administrators. In order to ensure the accuracy of the data, two data entry clerks should independently carry out double entry, and the two databases should be compared and verified after the entry is completed. For the questions in the case report form, the data manager will generate a data question sheet (DQF) and send an inquiry to the investigator through the clinical monitor, and the investigator should answer and return as soon as possible, and the data manager will modify, confirm and enter the data according to the investigator's answers, and can issue the data question form again if necessary. All question forms and answers should be kept for future reference. Then, 5% of the CRF tables were randomly checked for raw data verification, and the error rate was controlled within 5%. After the data is reviewed and the database is confirmed, the principal investigator, the sponsor, and the statistical analyst will lock the database, and the locked data file will not be changed and submitted to the statistical analyst for data processing.
