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)建立电子化病例报告表(eCRF):由各中心研究人员及时、准确录入患者基线资料、干预措施、观察指标及随访数据,数据录入后需双人核对。 2)数据监查:设立数据监查员,每3个月对各中心数据进行监查,核查数据的完整性、准确性和真实性,及时发现并纠正数据错误。 3)数据保密:所有研究数据均采用匿名化处理,以研究编号代替患者姓名,电子数据加密存储,纸质资料专人专柜保管,符合医学伦理要求。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1)An electronic Case Report Form (e-CRF) will be established. Researchers at each center will promptly and accurately enter patients' baseline information, intervention details, observation indicators, and follow-up data. All data entries will undergo dual independent verification. 2) Data monitoring: Data monitors will be assigned to review the data from each center every three months, checking for completeness, accuracy, and authenticity, and to promptly identify and correct any data errors. 3) Data confidentiality: All research data will be anonymized, with study identification numbers replacing patient names. Electronic data will be stored in encrypted formats, and paper documents will be kept in dedicated cabinets under the responsibility of designated personnel, in compliance with medical ethics requirements. |
