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,将及时、完整、正确、清晰地填写病例报告表。监查员监督临床研究是否遵循研究方案。确认所有病例报告表填写正确完整,并与原始 资料一致。如有错误和遗漏,及时要求研究者更正。修改时需保持原有记录清晰可见。经过监查员检查的病例报告表,由监查员核查签字后,及时送交临床试验数据管理部门 的管理员。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,要求研究者做出回答。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独立双份录入。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。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:
|
According to the original observation record of the subject the investigator will fill in the case report form promptly completely correctly and clearly. The monitor monitors whether the clinical study is following the study protocol. Verify that all case report forms are completed correctly and in accordance with the original data. If there are errors and omissions ask the researcher to correct them promptly. Ensure that the original records are clearly visible when you modify them. The case report form examined by the supervisor shall be checked and signed by the supervisor and promptly sent to the administrator of the clinical trial data management department. The transmission of the completed case report form between the researcher the monitor and the data manager shall be specially recorded and the corresponding signature shall be given upon receipt. The record shall be properly kept. The data manager checks the data again before data entry notifies the supervisor in time when problems are found and asks the researcher to answer them. The exchange of questions and answers between them shall be in the form of a question table which shall be kept for future reference. Before data entry the data manager should understand the contents and coding situation of each item in the observation form and record the coding process in the coding book. The database name should be standardized easy to read easy to find and ensure its correctness security and confidentiality. Data entry clerk input data using independent double entry. If any problem or accident is found in the input process it should be registered and reported in time so as to solve the problem quickly. After data entry part of the observation form should be checked randomly to understand the input quality analyze and deal with the existing problems. The data manager together with the principal investigator should formulate data range checks and logic checks based on the range and interrelationship of the values of the indicators in the case report form. And write the corresponding computer program before input control error data input find out the cause of the error to correct all error content and modification results should be recorded and properly stored.
