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:

数据管理 本研究将采用电子数据采集(EDC)系统采集数据。数据管理相关操作遵循以下步骤,具体操作将按照本研究的数据管理计划进行。 1. 电子病例报告表(eCRF)填写 电子病例报告表由研究者或者研究者指定人员(需在研究授权表中注明)依据源文件(原始病历、检查报告单等)填写,需确保信息的真实性、完整性和准确性。EDC系统将自动记录和保留所有操作的稽查轨迹,包括数据录入和更改的时间、操作人、数据更改原因、更改前数据值、更改后数据值等,以保证数据的可溯源性。 2. 数据核查 eCRF填写完成后,按照数据核查计划通过EDC系统设置的程序核查和人工核查等方式对数据进行核查。对核查中发现的可疑数据点,研究者或者研究者指定人员应及时更正或澄清。数据核查不限于EDC数据,还包括EDC数据与外部数据的一致性核查等。 3. 数据质量保证 本研究将采用质量控制和数据验证流程,以确保临床数据库的可靠性和准确性。监查计划和数据管理计划将详细列出所有相关研究工作人员需要遵循的数据录入、核查、澄清和验证流程,以确保遵从临床研究质量管理规范。 4. 数据库锁定 在所有疑问均得到解决并确认数据库中的数据完整、准确无误后,由研究者代表、临床项目经理、数据管理人员、医学监查人员、统计分析人员共同批准,由数据管理人员对数据库进行锁定,锁定后传输给统计师进行后续的统计分析。

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

Data management This study will use electronic data acquisition (EDC) system to collect data. The following steps will be followed for data management-related operations, which will be carried out in accordance with the data management plan of this study. 1. Complete the Electronic Case Report Form (eCRF) The electronic Case report Form (ECRF) shall be completed by the investigator or investigator designee (as indicated in the research authorization form) based on the source documents (original medical records, examination reports, etc.), and shall ensure the authenticity, completeness, and accuracy of the information. The EDC system will automatically record and retain the audit trail of all operations, including the time of data entry and change, the operator, the reason for data change, the data value before the change, the data value after the change, etc., to ensure data traceability. 2. Data verification After filling in the eCRF, the data shall be verified according to the data verification plan through the procedure verification and manual verification set by the EDC system. For suspicious data points found in the verification, the researcher or the researcher's designated personnel should be corrected or clarified in time. Data verification is not limited to EDC data, but also includes consistency verification between EDC data and external data. 3. Data quality assurance The study will employ quality control and data validation processes to ensure the reliability and accuracy of the clinical database. The monitoring plan and data management plan will detail the data entry, verification, clarification and validation processes that all relevant study staff will need to follow to ensure compliance with clinical study quality management practices. 4. Database locking After all questions are solved and the data in the database is confirmed to be complete and accurate, the research representative, clinical project manager, data management personnel, medical monitoring personnel and statistical analysis personnel jointly approve the data manager lock the database and transmit the lock to the statistician for subsequent statistical analysis.
