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)数据收集、记录与保存: 源文件是受试者参与试验的证明文件,也是验证所收集数据完整性的依据。所有源文件应保存于研究者的试验中心。所有评估数据需首先录入受试者档案(包含试验编号、受试者ID、入组日期及终止日期),随后转录至电子病例报告表(eCRF)。认知测试、神经精神评估及其他量表数据应直接记录于纸质表格,这些纸质记录视为原始数据来源,最终也需转录至eCRF系统。从源文件转录至eCRF的数据必须与源文件保持一致,若存在差异需提供合理解释。研究者可能需要调取受试者既往医疗记录或转诊记录进行核对。研究者应确保源文件和试验记录的充分性及准确性,其中需包含所有与受试者相关的观察记录,并能支持eCRF中的录入信息。源数据必须满足可溯源性、清晰性、即时性、原始性、准确性和完整性要求。任何源数据修改必须可追踪,不得覆盖原始记录,非自明性修改需附加说明(如通过审计追踪)。 2)数据收集与录入: 采用eCRF进行数据采集和录入。系统中所有方案要求的内容必须完整填写,未填写项需说明原因,并在各表格备注栏中注明具体事由。 3)EDC系统数据导出: eCRF数据导出至机构内部网络专用安全服务器形成数据库后,数据管理员将进行校对。明显错误由数据管理员直接修正,其他类型错误(包括但不限于格式错误、逻辑矛盾、内容表述不清等)及缺失值将通过数据质询表反馈至参与中心处理。 各参与中心在核实原始数据及相关信息后负责修正eCRF数据。研究者需通过验证或修改相关信息来回应质询。经双重审核的病例报告表将由临床监查员(CRA)提交至试验指定数据管理中心,由中心负责人签收确认。数据管理中心应妥善处理并保存接收的病例报告表。EDC系统可导出PDF格式的受试者数据,所有受试者的eCRF将由系统导出并由国家神经疾病临床研究中心(NCRC-ND)数据管理部门备份。 研究者需确保CRF/eCRF中数据的可分配性、可读性、即时性、原始性、准确性和完整性。 所有数据应由研究者或授权人员通过验证的电子远程数据采集系统(eCRF)及时录入(通常在源数据收集后5个工作日内完成)。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1)Data collection, documentation and retention: Source documents provide evidence for the existence of the participant and substantiate the integrity of the data collected. Source documents are filed at the Investigator’s site. All assessments will be initially entered in the participant’s file (incl. trial number, and participant ID, enrollment date, and termination date) and subsequently transcribed to the eCRF. All cognitive tests and neuropsychiatric and other rating scales will be directly entered on paper forms, which will be considered as source data. These data will also be transcribed to the eCRF. Data entered in the eCRF that are transcribed from source documents must be consistent with the source documents, or the discrepancies must be explained. The Investigator may need to request previous medical records or transfer records. The Investigator maintains adequate and accurate source documents and trial records, which include all pertinent observations on each of the site’s trial participants and that support the information entered in the eCRF. Source data must be attributable, legible, contemporaneous, original, accurate, and complete. Changes to source data must be traceable, do not obscure the original entry, and need to be explained if they are not self-explicatory (e.g., via an audit trail). 2)Data collection and entry: Electronic case report form (eCRF) will be used for data collection and entry. All the content required by the protocol in the system must be provided, the unfilled content should be explained, and the reason needs to be filled in the remarks under each form. 3)Data exportation from the EDC system: After the data from the eCRF is exported to a secure data server that uses only the internal network of the organization to form a database, it will be proofread by the data administrator. Obvious errors will be corrected by the data administrator. Other errors (including but not limited to formal errors, inconsistencies, unclear entries in term of content) or missing values will be filled in the data query form and returned to the participating center for solution. The participating centers are responsible for correcting the data in the eCRF after verifying the original data and related information. Site Investigators must answer these queries by verifying or modifying relevant information or data. The double reviewed case report form will be sent to the trial-designated data management center by clinical research associates (CRAs). The person in charge of the data management center will check and sign for receipt. The data management center should carefully enter and process the received case report forms and keep them properly. The EDC system can export each subject's data as a PDF. Each subject's eCRF will be exported by the system and backed up by the Data Management department at NCRC-ND. The Investigator is responsible for the allocation, legibility, contemporaneousness, originality, accuracy, and completeness of data documented in the CRF/eCRF. All data will be entered in a timely manner (usually within 5 working days after source data collection) by the Investigators or authorized trial team members on a continuous basis using a validated electronic remote data capture system (eCRF). |
