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:
|
1.建立数据库:根据病例报告表的项目采用计算机软件CDMS建立相应的录入程序,并设定录入时的逻辑审查限定条件,对数据库进行试运行,建立本试验专用的数据库系统;
2.录入前再次核查:对病例报告表的进一步检查,已经审核声明签字的病例报告表交给数据管理员,数据管理员对日期、入组标准、排除标准、脱落、缺失值等进行检查,如有疑问,可填写疑问表(query form)返回监察员,由研究者对疑问表中的问题进行书面解答并签名,交回数据管理员,疑问表应妥保管;
3.数据录入:对数据录入员培训后进行远程数据录入,每一份病例报告表采用双份录入法,由两人独立完成;
4.数据的审核:采用计算机软件中的核查功能进行逻辑检查与自动比较,查对与病例报告表不一致的结果值,然后逐项与原始病例报告表核对,予以更正。再进行病例报告表和数据库中的数据的人工比较,以确保数据库中的数据与病例报告表中的结果一致;
5.数据锁定:除进行上述的数据审核外,还要由主要研究者、统计人员、数据管理员和申办者共同进一步讨论和确认研究方案中的主要内容和统计分析计划书。进行盲态审核(b1ind review),确认全部数据均已录入数据库,全部疑问均已解决,分析人群已定义并做出判断后锁定数据(date locked);
6.揭盲和数据处理:数据锁定后,由保存盲底的单位向数据管理人员提交盲底,由后者完成数据的揭盲。揭盲后的数据交统计分析人员进行分析。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:
|
1. Establish a database: According to the project of the case report form, use the computer software CDMS to establish the corresponding entry procedure, and set the logical review qualification conditions at the time of entry, conduct trial operation on the database, and establish a database system dedicated to the test;
2. Check again before entering: further check on the case report form, the case report form signed by the audit statement is given to the data administrator, and the data manager checks the date, the entry criteria, the exclusion criteria, the dropout, the missing value, etc. If in doubt, you can fill out the inquiry form and return to the inspector. The researcher will answer and sign the questions in the question form in writing and return it to the data administrator. The question form should be kept safely;
3. Data entry: Remote data entry after training for data entry personnel. Each case report form adopts double entry method, which is completed by two people independently;
4. Data review: Use the verification function in the computer software to perform logical check and automatic comparison, check the result value that is inconsistent with the case report form, and then check the original case report form item by item and correct it. Manual comparison of the data in the case report form and the database to ensure that the data in the database is consistent with the results in the case report form;
5. Data Locking: In addition to the above data review, the main content and statistical analysis plan of the research program will be further discussed and confirmed by the main researchers, statisticians, data administrators and sponsors. Conduct blind audit (b1ind review), confirm that all data has been entered into the database, all questions have been resolved, the analysis of the population has been defined and judged to lock the data (date locked);
6. Unblinding and data processing: After the data is locked, the unit that saves the blind bottom submits a blind bottom to the data management personnel, and the latter completes the unblinding of the data. The data after unblinding was analyzed by statistical analysts.
