需在临床试验中的原始记录或者核证副本上记载所有信息,包括临床试验中产生的原始记录、文件和数据,如医院病历、医学图像、实验室记录、备忘录、受试者日记或者评估表、发药记录等。研究者或经研究者授权临床研究协调(CRC)根据受试者的原始资料信息填写受试者信息至病例报告表(CRF)。记录在CRF信息应与记录在原始记录中的源数据一致。

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

All information must be recorded in the original records or certified copies during the clinical trial, including original records, documents, and data generated in the trial, such as hospital medical charts, medical images, laboratory records, memoranda, subject diaries or assessment forms, and drug dispensing records. The investigator, or a clinical research coordinator (CRC) authorized by the investigator, will enter subject information into the case report form (CRF) based on the subject’s source documents. The data recorded in the case report form (CRF) must be consistent with the source data documented in the original records.
