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: |
数据管理: 1. 数据采集/管理系统建立:采用基于电子数据捕获(EDC)系统的数据库进行数据管理,由专业数据管理人员联合研究团队设计标准化病历报告表(CRF),明确数据采集项目、填写规范及编码标准,涵盖研究参与者基本信息、纳入排除标准评估结果、干预参数、有效性及安全性评价指标、不良事件记录等内容。数据库建立后进行系统测试与验证,确保数据录入逻辑合理、字段约束有效,避免数据缺失或错误。 2. 数据接收与录入:研究数据由经过培训的研究人员根据原始病历、检查报告、干预记录等原始资料及时、准确录入EDC系统,录入完成后由录入人员自行核对,确保录入数据与原始资料一致。对于纸质版原始资料,由专人负责收集、整理并编号归档,作为数据溯源依据。 3. 数据核查:数据录入完成后,启动自动核查与人工核查双重机制。自动核查由EDC系统根据预设逻辑(如范围核查、逻辑核查、一致性核查)筛选异常数据,生成数据疑问清单;人工核查由数据管理人员及研究负责人分阶段对录入数据进行抽查,重点核查关键指标(如PSQI评分、HAMA评分、不良事件信息)的准确性,对发现的疑问及时标记。 4. 数据审核与疑问解决:数据管理人员将数据疑问清单反馈给对应的研究人员,研究人员需在收到疑问后3个工作日内核实原始资料并给出明确答复,对错误数据进行修正,对合理疑问进行解释说明。修正后的信息需再次经数据管理人员审核确认,确保疑问妥善解决,形成数据疑问解决记录并归档。 5. 数据库锁定:当所有研究数据录入完成、数据疑问全部解决、研究结束后,由数据管理人员提交数据库锁定申请,经研究负责人、统计分析师审核确认后,对数据库进行锁定。数据库锁定后,任何人员不得擅自修改数据,若因特殊原因(如发现严重数据错误)需解锁,需提交书面申请,经研究负责人及伦理委员会批准后,由指定人员完成修改并详细记录修改原因、内容及时间,修改完成后重新锁定数据库。 6. 数据导出及传输:数据库锁定后,由统计分析师在数据管理人员协助下,将数据以规范格式(如SAS数据集)导出,导出过程全程留痕。数据传输采用加密传输方式,确保数据在传输过程中的安全性,传输完成后由接收方确认数据完整性。 7. 数据及数据管理文件的归档:数据管理相关文件(包括CRF设计方案、数据库测试报告、数据疑问清单及解决记录、数据库锁定申请及审批文件、数据导出及传输记录等)与研究数据一同归档,纸质文件归档于首都医科大学宣武医院临床试验机构档案室,电子数据加密存储于医院专用数据服务器,归档期限不少于研究结束后5年,归档期间由专人负责管理,严格控制访问权限,确保数据可追溯性和安全性。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data Management Establishment of Data Collection and Management SystemData management will be performed based on an Electronic Data Capture (EDC) system. A professional data management team, in collaboration with the research team, will design standardized Case Report Forms (CRFs). Data collection items, completion specifications and coding standards will be clearly defined, covering participants’ basic information, eligibility assessment results of inclusion and exclusion criteria, intervention parameters, efficacy and safety evaluation indicators, and adverse event records. System testing and validation will be conducted after database construction to ensure reasonable data entry logic and effective field constraints, so as to prevent data missing and errors. Data Reception and EntryTrained researchers will timely and accurately input research data into the EDC system according to original medical records, examination reports, intervention records and other source documents. After entry completion, the operator will conduct self-verification to guarantee consistency between entered data and original source data. Paper-based source documents will be collected, sorted, numbered and filed by designated personnel for data traceability. Data VerificationA dual mechanism of automatic verification and manual verification will be implemented following data entry. Automatic verification will be performed by the EDC system to screen abnormal data according to preset logical rules including range check, logic check and consistency check, and generate data query lists. For manual verification, data managers and principal investigators will conduct periodic spot checks on entered data, with emphasis on the accuracy of key indicators such as PSQI scores, HAMA scores and adverse event information. All identified queries will be marked in a timely manner. Data Review and Query ResolutionData managers will feedback data query lists to corresponding researchers. Researchers shall verify original source documents and provide clear responses within 3 working days upon receipt of queries. Erroneous data will be corrected, and reasonable queries will be explained. Revised information shall be re-reviewed and confirmed by data managers to ensure proper resolution of all queries. Records of query resolution will be formed and archived. Database LockUpon completion of all data entry, full resolution of all data queries and study termination, data managers will submit an application for database lock. The database will be locked after review and confirmation by the principal investigator and statistical analyst.No unauthorized data modification is permitted after database lock. Unlocking is only allowed for special circumstances such as serious data errors, which requires a written application approved by the principal investigator and the Ethics Committee. Modifications will be performed by designated personnel with detailed records of modification reasons, contents and time. The database will be re-locked after revision. Data Export and TransmissionAfter database lock, statistical analysts will export data in standard formats (e.g. SAS datasets) with assistance from data managers, with the whole export process fully traceable. Encrypted transmission will be adopted to ensure data security during transmission. The receiver shall confirm data integrity upon completion of transmission. Archiving of Data and Data Management DocumentsAll data management documents, including CRF design protocols, database test reports, data query lists and resolution records, database lock application and approval documents, as well as data export and transmission records, will be archived together with study data.Paper documents will be stored in the archives of the Clinical Research Institute of Xuanwu Hospital, Capital Medical University. Electronic data will be encrypted and saved on the hospital’s dedicated data server. The retention period shall be no less than 5 years after study completion. Specialized personnel will be responsible for archive management with strictly restricted access permissions to ensure data traceability and security. |
