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. 数据采集与记录(At Site)责任人员:研究者(PI/Sub-I) 是源数据准确性的第一责任人。研究协调员(CRC) 负责协助整理和转录。 (1) 可归因(Attributable):所有源文件上的记录必须由执行者签名并签署日期(签名+日期),确保所有数据可追溯至产生者。 (2) 及时(Contemporaneous):所有临床观察和活动需在发生后立即记录,严禁事后补记或追溯性修改。 (3) 清晰、持久(Legible, Enduring):使用不褪色的黑色签字笔书写,字迹清晰。电子记录需使用授权账户登录。 (4) 修改规范:任何错误的修改必须采用“划改”方式:单线划掉错误数据,在旁边书写正确数据,签名并注明日期,解释修改理由(如需要)。严禁使用涂改液覆盖或完全涂黑。 2. 数据录入(At Site → to eCRF) (1) 责任人员:由经过授权的CRC负责将源数据转录至eCRF系统。 (2) 要求: A.时限:数据需在访视结束后3个工作日内录入eCRF。 B.准确性:必须与源文件完全一致。 C.录入跟踪:eCRF系统将自动记录录入者身份、录入和修改时间戳,确保操作轨迹可追溯。 3. 数据核对与质疑管理(Central) (1) 责任人员:数据管理员(DM) 负责执行;CRC和研究者负责解答。 (2) 核对制度: A.自动逻辑核查(Edit Checks):eCRF系统内预设程序化逻辑检查规则(如数值范围、跨表单逻辑矛盾、必填项缺失等),在数据录入时或定期运行,实时产生质疑(Query)。 B.人工审核:DM定期对数据进行人工审核,针对异常趋势、缺失数据、不一致信息等提出人工质疑。 (3) 质疑管理流程: A. 产生:DM在eCRF系统中发布质疑。 B. 通知:系统自动邮件通知CRC。 C. 解答:CRC协同研究者查阅源文件,核实数据。 (4) 回复:在eCRF系统中对质疑进行回复: A.若数据无误,提供解释性说明。 B.若数据有误,直接修改数据并说明原因。 (5) 关闭:DM审核答复后关闭质疑。所有质疑及解答记录将被永久保存。 4. 源数据核查(Source Data Verification, SDV) (1) 责任人员:临床监查员(CRA)。 (2) 制度:CRA定期到各中心,将eCRF中的数据与源文件进行比对核查,以确保数据转录的准确性。本研究计划对100%的主要终点数据和不低于10%的随机抽取的常规数据进行SDV。 5. 数据锁定与归档 (1) 责任人员:DM、统计师、PI。 (2) 流程: A.数据库冻结:当所有数据录入完毕且质疑全部关闭后,DM冻结数据库,不再进行任何修改。 B.盲态审核:召开由PI、统计师、DM参加的盲态审核会,对冻结的数据进行最终审核,并决定是否锁定数据库。 C.数据库锁定:审核通过后,由DM、PI和统计师共同授权,正式锁定数据库。锁定后任何更改均需严格的《数据库解锁SOP》流程审批。 D.数据归档:锁定的数据库、所有eCRF数据、质疑记录、数据管理计划等,将以不可编辑的格式(如PDF, XPT)归档,长期保存至研究结束后至少5年。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1. Data Collection and Documentation (At Site) Person Responsible: Investigator (PI/Sub-I): The primary person responsible for the accuracy of source data. Clinical Research Coordinator (CRC): Assists with data organization and transcription. (1) Attributable: All entries on source documents must be signed and dated by the person performing the activity (signature + date), ensuring traceability to the individual who generated the data. (2) Contemporaneous: All clinical observations and activities must be documented immediately upon occurrence. Retroactive documentation or post-hoc revisions are strictly prohibited. (3) Legible, Enduring: Use non-erasable black signature pens with clear handwriting. Electronic records must be created via authorized user accounts. (4) Standard for Corrections: Any error correction must be done by strikethrough: draw a single line through the incorrect data, write the correct data nearby, sign and date the correction, and explain the reason (if necessary). Correction fluid or full blackout is not allowed. 2. Data Entry (At Site → to eCRF) (1) Person Responsible: Authorized CRC transcribes source data into the eCRF system. (2) Requirements: A. Timeline: Data must be entered into the eCRF within 3 working days after the visit. B. Accuracy: Must be fully consistent with source documents. C. Entry Tracking: The eCRF system automatically records the identity of the person entering data, as well as timestamps for entry and modifications, ensuring traceability of all operations. 3. Data Review and Query Management (Central) (1) Person Responsible: Data Manager (DM) performs reviews; CRC and Investigator resolve queries. (2) Review System: A. Automated Edit Checks: Programmed logic check rules (e.g., value ranges, inter-form inconsistencies, missing mandatory fields) are pre-set in the eCRF system. They run during data entry or periodically and generate queries in real time. B. Manual Review: DM conducts regular manual reviews and raises manual queries for abnormal trends, missing data, inconsistent information, etc. (3) Query Management Process: A. Generation: DM issues queries in the eCRF system. B. Notification: System automatically notifies CRC via email. C. Resolution: CRC, in collaboration with the Investigator, reviews source documents and verifies data. (4) Response: Respond to queries in the eCRF system: A. If data are correct: Provide an explanatory note. B. If data are incorrect: Revise data directly and state the reason. (5) Closure: DM reviews responses and closes queries. All queries and resolutions are permanently retained. 4. Source Data Verification (SDV) (1) Person Responsible: Clinical Research Associate (CRA). (2) Policy: CRA conducts regular on-site visits to compare eCRF data against source documents to ensure accuracy of transcription. For this study, SDV will be performed on 100% of primary endpoint data and no less than 10% of randomly selected routine data. 5. Data Lock and Archiving (1) Person Responsible: DM, Statistician, PI. (2) Process: A. Database Freeze: After all data are entered and all queries are closed, DM freezes the database; no further modifications are permitted. B. Blind Review: A blind review meeting is held with PI, Statistician, and DM to perform final review of the frozen data and decide whether to lock the database. C. Database Lock: Following successful review, the database is formally locked under joint authorization by DM, PI, and Statistician. Any post-lock changes require strict approval in accordance with the SOP for Database Unlocking. D. Data Archiving: The locked database, all eCRF data, query records, Data Management Plan, etc., will be archived in non-editable formats (e.g., PDF, XPT) and retained long-term for at least 5 years after study completion. |
