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:(1)电子数据采集系统:使用专业的电子数据采集系统或建立加密的电子数据库(如使用Research Electronic Data Capture系统,或密码保护的Excel/Access模板,并定期备份)。(2)双重录入与核对:由两名独立的数据录入员将纸质《病例报告表》中的数据录入电子系统。系统自动比对两次录入结果,任何不一致处将触发核对并修正流程,直至完全一致。(3)盲态数据录入:实验室指标的检测结果,将仅使用随机编码录入数据库,绝不允许录入任何可能揭示分组的信息。分组信息(盲底)由独立的研究协调员单独加密保存。 2. 数据管理:(1)在EDC系统中预设逻辑检查规则(如数值范围核查、必填项核查、日期逻辑核查),且主要研究者或指定人员定期审查数据,判断其医学合理性;(2)在所有数据录入、清理完毕后,在保持盲态(分析人员仅能看到样本编码和对应数据)的情况下,进行最终的数据库审核与锁定;(3)数据应保存在机构指定的安全服务器或加密的移动硬盘中。服务器需有防火墙、防病毒及定期安全审计。纸质文件:包括签署的知情同意书、原始病历记录、CRF等,存放于研究机构的带锁文件柜中,由专人管理。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1. Data Collection:(1) Electronic Data Capture (EDC) System: A specialized EDC system or encrypted electronic database was utilized (e.g., Research Electronic Data Capture (REDCap) system, or password-protected Excel/Access templates with regular backups).(2) Double Data Entry and Verification: Two independent data entry personnel input data from paper Case Report Forms (CRFs) into the electronic system. The system automatically compared the two entries; any discrepancies triggered a review and correction process until complete consistency was achieved.(3) Blinded Data Entry: Results of laboratory tests were entered into the database using randomized codes only. Entry of any information that could reveal group assignment was strictly prohibited. The group allocation information (unblinding codes) was stored separately under encryption by an independent study coordinator.2. Data Management:(1) Predefined logic check rules (e.g., range checks, mandatory field verification, date logic validation) were set in the EDC system. The principal investigator or designee regularly reviewed the data for medical plausibility.(2) After all data entry and cleaning were completed, a final review and database lock were performed while maintaining the blind (analysts could only see sample codes and corresponding data).(3) Data were stored on the institution's designated secure servers or encrypted portable hard drives. Servers were protected by firewalls, antivirus software, and underwent regular security audits.(4) Paper documents, including signed informed consent forms, original medical records, and CRFs, were stored in locked filing cabinets at the research institution and managed by designated personnel. |
