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.数据采集由我院经过统计培训的曹雯萍医师采用盲法进行,数据录入与管理由我院范理强医师负责。临床试验启动前的数据监察一般在现场核察,所有数据采集准备工作完成后书面报告课题负责人王斌及我院数据安全与监察委员会(DSMB)。
2.试验进行中的数据监察根据数据库不同采用不同的方法,主要采用计算机本机数据库录入,数据库须能追溯任何更改。数据监察定期在现场进行,试验进行中期分析时,一般是纳入参试者一半时进行。中期分析前要先截止数据录入,再进行数据监察并编制监察结果清单。
3.试验数据收集完成后要进行最后的数据监察,在现场对外部数据材料等进行审核验收。数据监察中发现的问题数据应及时汇总分类,分别向不同数据来源的责任人发出质询函,经核对无误后由数据录人员或数据库管理员进行更正 。
4.临床试验中期分析和试验结束的数据监察完成后,为了防止意外或未授权的更改,均需要将数据库锁定,即取消所有人员的编辑权限。锁定数据库前必须向DSMB、课题负责人报告,并附数据监察清单,在获得书面签字批准后锁定数据库 。
5.数据库锁定后,如需要重新开锁继续录入数据或对错误数据进行修正,均需获得DSMB的批准并详细记录。重新开锁的条件和操作流程:中期分析完成后继续开始后半程试验; 数据库锁定后新发现遗漏数据或错误。由DSMB批准授权后,数据库管理员和监察员实施重新开锁,修改完成后除数据库自动记录修改操作外,还需将纸质授权批件和执行情况记录归档保存。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:
|
Cao Wenqiang and our hospital doctors will be responsible for data collection and management. The data monitoring before the start of clinical trials is generally carried out on the spot. After all the data collection preparations are completed, a written report will be submitted to the project leader Wang Bin and the data security and Supervision Committee (DSMB) of our hospital.
2. The data monitoring during the test will adopt different methods according to different databases, mainly using the computer local database input, and the database must be able to trace any changes. Data monitoring is carried out on site regularly, and the mid-term analysis of the trial is generally carried out when half of the participants are included. Before the mid-term analysis, the data entry should be cut off, then the data monitoring should be carried out, and the list of monitoring results should be compiled.
3. After the test data collection is completed, the final data monitoring shall be carried out, and the external data materials shall be checked and accepted on site. The problem data found in the data monitoring shall be summarized and classified in time, and the inquiry letters shall be sent to the responsible persons of different data sources respectively. After verification, the data recorder or database administrator shall correct it.
4. After the interim analysis of clinical trial and data monitoring at the end of the trial, in order to prevent accidental or unauthorized changes, the database should be locked, that is, to cancel the editing authority of all personnel. Before locking the database, it is necessary to report to DSMB and the project leader, and attach the data monitoring list, and lock the database after obtaining the written signature and approval.
5. After the database is locked, if it is necessary to re unlock, continue to input data or correct the wrong data, it is required to obtain the approval of DSMB and make detailed records. The conditions and operation process of re unlocking: after the completion of the mid-term analysis, the second half of the test should be continued; after the database is locked, new missing data or errors are found. After the authorization is approved by DSMB, the database administrator and the supervisor implement the re unlocking. After the modification, in addition to the automatic record of the modification operation in the database, the paper authorization approval documents and the implementation records need to be filed and saved.
