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:

研究数据收集将以CRF表、病历为主,相关实验室检查、影像检查结果及不良反应情况均在CRF表中进行记录。CRF表填写将由Sub-I完成。项目负责人将对报告数据的准确性、完整性、及时性负责。所有数据应清晰以确保准确的解释,并保证其可溯源性。 本研究开展后,将由临床研究小组成员进行定期(每季度)研究数据记录核查,并通过线上会形式沟通研究进度及研究质量,由瑞金医院肿瘤科蒋金玲医生和三明市第一医院肿瘤放化疗科周志连医生分别担任质控负责人。受试者筛选将由PI与Sub-I共同确认后进行。本研究所有参与者均通过GCP培训,并在研究过程中每3-6个月进行GCP相关培训。

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

The data collection will utilize Case Report Forms (CRFs) and medical records, with all relevant laboratory test results, imaging findings, and adverse events documented in the CRFs. The completion of CRFs will be performed by Sub-Investigators (Sub-Is). The Principal Investigator (PI) will be responsible for ensuring the accuracy, completeness, and timeliness of the reported data. All data entries must be legible to guarantee precise interpretation while maintaining traceability. Following study initiation, the clinical research team will conduct quarterly audits of research data documentation and communicate study progress.
