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:

EDC; 本研究没有纸质版本病例报告表、所有的采集内容均由临床协调员依据原始病历进行录入。临床协调员在数据录入前需经统一培训并获得授权,应该保证认真、完整、正确的将数据录入到电子数据库中。录入完成后需要进行针对数据录入的质量控制,保证数据准确性。

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

EDC; This study did not print case report, all collection content was recorded by the clinical coordinator based on the original medical records. Clinical coordinators are uniformly trained and authorized prior to data entry, and should ensure that data is entered into electronic databases carefully, completely and correctly. After the completion of the entry, quality control for data entry is required to ensure data accuracy.
