临床试验数据资料应记录于专门设计的研究表格中,为受试者医疗源文件,记录和审核要求包括: (1)研究者必须在诊治受试者同时书写研究病历,保证数据记录及时、完整、准确、真实。 (2)研究病历做任何有证据的更正时只能划线,旁注改后的数据,由研究者签名并注明日期,不得擦除、覆盖原始记录。 (3)每一位受试者治疗与随访结束后,研究者应将研究病历等交本单位主要研究者审核、签名并存于资料档案室,发现问题及时处理并记录。

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

Clinical trial data and information shall be recorded in specially designed study forms, which serve as the source medical documents for subjects. The requirements for recording and review are as follows: (1) Investigators must complete the study medical records at the time of diagnosing and treating subjects, ensuring that all data records are timely, complete, accurate and truthful. (2) Any justified corrections to the study medical records shall only be made by drawing a single line through the original entry, with the corrected data noted in the margin, and signed and dated by the investigator. Erasure or overwriting of the original record is strictly prohibited. (3) Upon completion of treatment and follow-up for each subject, the investigator shall submit the study medical records and other relevant documents to the principal investigator (PI) of the institution for review, signature, and filing in the data archive room. Any issues identified during the review shall be promptly addressed and documented.
