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: |
数据采集与方式 本试验采用电子化数据采集系统(EDC)进行数据采集,数据管理员/数据库程序员根据不同身份,分别创建账号,授予不同权限访问EDC系统。 eCRF记录的数据应来自源文件,并保证与源数据一致。所有源文件应保持清晰、整洁,确保数据能够准确辨识。研究访视记录的永久副本将被视为源文件,用以记录入选受试者数据。录入人员应及时、准确地将研究病历等源文件中的数据录入eCRF。 数据清理与质疑解决 数据清理工作包括数据核查(系统逻辑检查与人工逻辑检查)、触发疑问、研究者/研究助理答疑、数据更新、直到疑问解决的过程。 数据管理员和监查员通过EDC系统定期进行数据清理,医学监查员通过EDC系统定期进行医学审核工作。对于EDC疑问,研究者/研究助理均在线给予解答和/或修改错误数据。疑问发起者对答疑数据进行确认,必要时可以重复发出疑问。 数据的修改和审核 数据录入人员或研究者核实数据后可对数据进行修改,修改的数据需在eCRF上填写修改理由。研究者对最终所有数据具有审核权限。 数据锁定及导出 所有数据审核无误后,数据管理员对数据进行锁定。数据锁定后如有修改,需经研究者、数据管理人员签字确认方可执行。所有数据最终由数据管理人员导入到指定数据库,交与统计人员进行分析。 研究结束,数据管理中心将保存电子化数据。 方案中未能详尽规定的数据管理相关工作参照本试验的数据管理计划执行。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data Collection and Methods This trial uses an Electronic Data Capture (EDC) system for data collection. Data managers/database programmers will create accounts and grant different access privileges to users based on their roles. Data recorded in the electronic Case Report Form (eCRF) should be derived from source documents and must be consistent with the source data. All source documents should be kept clear and tidy to ensure accurate data interpretation. Permanent copies of study visit records are considered source documents for recording enrolled subjects' data. Data entry personnel should promptly and accurately input data from source documents such as study medical records into the eCRF. Data Cleaning and Query Resolution Data cleaning includes processes such as data verification (system logic checks and manual logic checks), triggering queries, responses from investigators/research assistants, data updates, and resolution of discrepancies. Data managers and monitors conduct regular data cleaning through the EDC system, while medical monitors perform periodic medical reviews via the EDC system. For EDC queries, investigators/research assistants provide online responses and/or correct erroneous data. Query initiators will confirm the responded data and may resend queries if necessary. Data Modification and Review Data entry personnel or investigators may modify data after verification, with the reason for modification recorded in the eCRF. Investigators have final review authority over all data. Data Locking and Export Once all data are verified error-free, data managers will lock the data. Any modifications after data locking require signed confirmation from investigators and data management personnel. Finally, all data will be imported into a designated database by data managers for analysis by statisticians. At the end of the study, the data management center will store the electronic data. Any data management tasks not explicitly specified in the protocol will be handled in accordance with the trial's Data Management Plan (DMP). |
