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: |
本研究采用纸质版病例记录表进行原始数据采集。CRF由研究者/临床研究协调员根据受试者原始病历及时、完整、准确填写,监查员定期核查CRF与原始记录的一致性。数据采集后采用双人双录入方式,由两名数据录入员分别独立将纸质CRF中的数据录入Excel数据库。录入完成后,利用软件对两份独立数据文件进行一致性比对,对照CRF逐一核对并解决不一致之处,直至两份数据完全一致。录入完成后对关键变量进行100%核查,非关键变量抽取5%进行人工核对。数据库设置访问权限,数据文件定期备份。数据质疑通过数据疑问表(DQF)形式向研究者提出,答疑后由研究者签字确认并归档。所有数据修改均保留修改记录,确保数据可追溯。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
This study employs a paper-based Case Report Form (CRF) for original data collection. The CRF is completed in a timely, complete, and accurate manner by the investigator or Clinical Research Coordinator (CRC) based on the subjects' original medical records. A monitor regularly verifies the consistency between the CRF and the source documents. Following data collection, a double data entry method is utilized, wherein two data entry personnel independently transcribe the data from the paper CRF into an Excel database. After entry, software is used to compare the two independent data files for discrepancies. Any inconsistencies are resolved by checking the data against the original CRF one by one until the two datasets are completely identical. Once the double entry reconciliation is complete, 100% of key variables are verified, while 5% of non-key variables are randomly selected for manual verification against the source CRF. Access to the database is restricted with appropriate permissions, and data files are backed up on a regular basis. Data queries are raised to the investigator in the form of a Data Query Form (DQF). Responses are confirmed by the investigator's signature and filed for archiving. All data modifications are documented with an audit trail to ensure full traceability. |
