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: |
数据来源:单中心前瞻性队列,纳入符合标准的胸腰椎骨折患者100例(定位器组50例,传统组50例) ,采集时点:术前、术中、术后3天、3个月、6个月;采集内容 :①基线:年龄、性别、BMI、骨折类型(AO分型)、椎体压缩率;②术中:手术时间、透视次数、辐射剂量、置钉准确率(CT三维重建验证);③影像:X线/CT测量椎体高度、Cobb角、椎管占位率;④功能:VAS评分、ODI指数、SF-36量表;⑤并发症:神经损伤、内固定松动、支撑器移位;采集方式:结构化电子病例报告表(eCRF),医院HIS/LIS/PACS系统自动抓取+人工双录入 ;质控措施:独立数据监查员(DM)每周核查逻辑一致性,关键影像由2名高年资医师盲法读片,分歧提交第三方仲裁 管理系统 :采用符合《药物临床试验质量管理规范》(GCP)的EDC系统(如REDCap或商业化平台),部署于医院内网服务器 ;数据安全:①传输:SSL加密;②存储:AES-256加密,每日增量备份+异地容灾;③权限:RBAC角色分级,仅研究者、DM、统计师可访问;④脱敏:患者姓名、身份证号替换为编码,编码本与数据库物理隔离保存;数据核查:①逻辑核查:系统内置范围校验(如年龄18-60岁)、跳转逻辑、缺失值提示;②人工核查:DM每月导出数据,10%随机抽样与原始病历核对,错误率>5%启动全面核查 ;数据归档 :研究结束后原始数据、分析数据集、编码本、数据管理计划保存15年,符合《临床试验数据管理工作技术指南》要求。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1. Data source: Single-center prospective cohort study, including 100 eligible patients with thoracolumbar fractures (50 in the locator group and 50 in the traditional group). Collection time points: preoperative, intraoperative, postoperative day 3, 3 months, and 6 months. Collection contents: (1) Baseline: age, gender, BMI, fracture type (AO classification), vertebral compression rate; (2) Intraoperative: operation time, fluoroscopy times, radiation dose, screw placement accuracy (verified by CT three-dimensional reconstruction); (3) Imaging: X-ray/CT measurement of vertebral height, Cobb angle, spinal canal occupancy rate; (4) Function: VAS score, ODI index, SF-36 scale; (5) Complications: nerve injury, internal fixation loosening, support device displacement. Collection method: Structured electronic case report form (eCRF), automatic extraction from hospital HIS/LIS/PACS systems + manual double entry. Quality control measures: Independent data monitors (DMs) verify logical consistency weekly, and key images are blindly read by two senior physicians, with disagreements submitted to a third-party arbitration system. 2. Management system: An EDC system compliant with the "Good Clinical Practice" (GCP) is adopted (such as REDCap or commercial platforms), deployed on the hospital's intranet server. 3. Data security: (1) Transmission: SSL encryption; (2) Storage: AES-256 encryption, daily incremental backup + off-site disaster recovery; (3) Access: RBAC role-based access control, accessible only to researchers, DMs, and statisticians; (4) Desensitization: Patient names and ID numbers are replaced with codes, and the code book is physically isolated from the database for storage. 4. Data verification: (1) Logical verification: System-built range checks (e.g., age 18-60 years), skip logic, missing value prompts; (2) Manual verification: DMs export data monthly, 10% random sampling is checked against original medical records, and comprehensive verification is initiated if the error rate > 5%. 5. Data archiving: After the study ends, original data, analysis datasets, code books, and data management plans are stored for 15 years, in compliance with the "Technical Guidelines for Clinical Trial Data Management Work". |
