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:

我们采用了两种主要的数据采集方式:病例记录表(CRF)和电子采集和管理系统(EDC)。 用纸质或电子版的标准化文档,用于详细记录每个参与者的医疗信息、生活习惯、膳食摄入等。CRF的设计遵循科学性和实用性的原则,确保能够全面反映参与者的各方面情况。在采集数据时,我们会对CRF的使用进行严格的培训,确保采集的数据真实、可靠。通过ResMan系统,我们可以实现数据的远程采集、实时监控和数据质量控制,大大提高了数据管理的效率和准确性。在数据采集过程中,我们始终注重数据的保护和安全。CRF和EDC系统都采用了严格的数据加密和权限管理措施,确保参与者的隐私得到充分的尊重和保护。同时,我们还将定期对数据进行备份和恢复测试,以防止数据丢失和损坏。

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

We use two main methods of data collection: the Case Record Form (CRF) and the Electronic Collection and Management System (EDC). Standardized documents in paper or electronic form are used to record each participant's medical information, lifestyle habits, dietary intake, etc. in detail. The CRF is designed to be scientific and practical, ensuring that all aspects of the participants are fully reflected. When collecting data, we will conduct rigorous training on the use of CRF to ensure that the collected data is true and reliable. Through the ResMan system, we can realize remote data acquisition, real-time monitoring and data quality control, which greatly improves the efficiency and accuracy of data management. In the process of data collection, we always pay attention to the protection and security of data. Both the CRF and EDC systems have adopted strict data encryption and permission management measures to ensure that the privacy of participants is fully respected and protected. At the same time, we will also conduct regular backup and recovery tests on data to prevent data loss and corruption.
