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、清晰地载入病例报告表。
监查员监查试验的进行是否遵循试验方案。确认所有病例报告表填写正确并与原始资料一致。如有错误和遗漏,及时要求研究者改正。修改时需保持原有记录清晰可见,改正处需经研究者签名并注明日期。
经过监查员检查后的病例报告表,由监查员核查签字后,及时送交临床试验数据管理员。
对于完成的病例报告表在研究者、监查员、数据管理员之间的传送应有专门的记录,收到时应有相应的签名,记录需妥善保存。
数据管理员在数据录入前再次核查,发现问题及时通知监查员,要求研究者作出回答。他们之间的各种疑问及解答的交换应当采用疑问表形式,疑问表应保存备查。
数据管理员在进行数据录入前,要了解观察表格各项目的内容及编码情况,将编码工作过程记录于编码本保存。数据库命名应规范、易读、易查找。并保证其正确、安全和保密。
数据录入员录入数据采用二次录入。录入过程发现问题或意外情况,应做好登记并及时报告,以便迅速处理问题,数据录入结束后应抽查部分观察表格,了解录入质量,分析并处理存在的问题。
数据管理员应与主要研究者一起,按病例报告表中各指标数值的范围和相互关系,拟定数据范围检查和逻辑检查内容。并编写相应的计算机程序,在输入前控制错误数据输入,找出错误原因加以改正,所有错误内容及修改结果应有记录并妥善保存。
原始病例报告表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,以备查考。电子数据文件包括数据库、检查程序、分析程序、分析结果、编码本和说明文件等,应分类保存,并有多个备份保存于不同磁盘或记录介质上,妥善保存,防止损坏。所有原始档案应按我国《药物临床试验质量管理规范》的规定期限保存。

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

They were according to the records of original observations, the data timely complete accurate load case report clearly examiner monitoring test to confirm whether to follow a protocol form to fill in all the cases correctly and consistent with the original data if there are any errors and omissions, request the correction in time when it needs to keep the original record is clearly visible, corrections need signature and dated by the researchers after arbitrator to check the case report form, signed by the arbitrator for verification, in a timely manner to the clinical trial data administrator for complete case report form in the arbitratorTransfer between data managers should have a special record, should have the corresponding signature when receiving, records should be properly kept data administrator before the data entry to check again, found that the problem timely notify the examiner, requires researchers to answer all sorts of question and answer exchange between them shall be in doubt table form, question list shall be kept for future reference data administrator before for data entry, to understanding the content of the observation form and coding, the coding process recorded in code stored in the database name shall be easy to read easy to find and to ensure that its security and privacy rightOperator input data using the secondary data typed entry process found problems or accidents, should be register and report in time, in order to deal with the problem quickly, after the data entry should be spot check some observation form and understand the quality of the input, data analysis and deal with the problems existing in the administrator shall, together with the principal investigator form according to the case of the range of each index and mutual relations, proposed the data range check and check the content and write the corresponding computer program logic, in front of the input control error data input, find out the reason for the error correction, content and modify all errors result should be recorded and properly keptOriginal cases report after the completion of data entry and verification as required in the numbered order archive preservation, and filled with catalog, etc., with reference to take an examination of the electronic data file including the database to check program analysis results of the analysis code book and documents, etc., shall be stored in classification, and have more than one backup save to disk or on a recording medium, different properly kept, prevent damage all original files should be in accordance with the drug clinical trial in our country and the quality control standard for save time limit.
