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:

一、病历记录表 本研究采用根据研究方案自行设计的专用病历记录表(或称病例报告表,CRF) 进行数据采集。该表格以纸质形式记录以下信息: 受试者基本资料与病史:身高、体重、腰围、BMI、心脑血管病史等。 影像学测量原始数据:由超声设备直接输出的肝脏SWE硬度值、ATT值、颈动脉cIMT值、WSS值;以及MRI-PDFF值。 血生化指标记录:从医院信息系统(HIS)中调取并转录的受试者当日血脂、血糖、肝酶等化验结果。 安全性数据:受试者的呼吸频率、脉搏等生命体征。 所有数据均由研究人员填写,确保字迹清晰、信息准确。纸质病历记录表将保存在科室带锁的文件柜中,与受试者签署的知情同意书一同妥善保管。 二、电子采集和管理系统 数据电子化与存储:将纸质病历记录表中的所有数据,使用Microsoft Excel软件录入并生成电子数据库。该数据库存储于同济大学附属同济医院内部加密服务器上,并设有密码保护。 匿名化处理:在电子化过程中,为每位受试者分配唯一的研究ID(格式:TJ-US-XXX),以替代所有个人身份信息(姓名、身份证号等),实现数据的完全匿名化。 权限管理:对电子数据库实行分级权限管理: 主要研究者(张兵、白文坤):拥有数据库的全部权限(录入、修改、查询、导出)。 研究医师:仅拥有数据录入和查询的权限。 统计分析师:仅能访问和分析已完成匿名化处理的最终数据集,无法追溯受试者身份。 质量控制: 数据录入采用双人独立录入或录入后二次核对机制,以确保准确性。 主要研究者或指定质控员每周随机抽取10%的影像数据和对应记录进行复核,确保数据获取与记录的规范性。 所有超声及MRI测量指标均遵循标准操作程序(SOP),关键指标(如ATT、cIMT)取多次测量平均值,以保障数据可靠性。

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

1. Medical Record Form This study used a dedicated medical record form (or case report form, CRF) designed according to the research protocol for data collection. This form records the following information in paper form: Basic information and medical history of the subjects: height, weight, waist circumference BMI History of cardiovascular and cerebrovascular diseases, etc. Imaging measurement raw data: liver SWE hardness value, ATT value, carotid artery cIMT value, WSS value directly output by ultrasound equipment; And MRI-PDFF values. Blood biochemical index record: the daily blood fat, blood sugar, liver enzyme and other test results of the subjects retrieved and transcribed from the hospital information system (HIS). Safety data: vital signs such as respiratory rate and pulse of the subjects. All data were filled in by researchers to ensure clear handwriting and accurate information. The paper medical record form will be stored in a locked filing cabinet in the department and kept properly together with the informed consent form signed by the subjects. 2. Electronic Collection and Management System Data electronicization and storage: Enter all data in paper medical record forms using Microsoft Excel software and generate an electronic database. The database is stored on an encrypted server within Tongji Hospital affiliated with Tongji University and is password protected. Anonymization: In the electronic process, each subject is assigned a unique research ID (format: TJ-US-XXX) to replace all personal identity information (name, ID number number, etc.), so as to achieve complete anonymity of data. Permission management: Implement hierarchical permission management for electronic databases: Main researchers (Zhang Bing, Bai Wenkun): have full access to the database (input, modify, query, export). Research physician: Only has the authority to input and query data. Statistical analyst: can only access and analyze the final dataset that has been anonymized, and cannot trace the identity of the subjects. Quality Control: Data entry adopts a two person independent entry or a secondary verification mechanism after entry to ensure accuracy. The main researcher or designated quality controller randomly selects 10% of the imaging data and corresponding records for review every week to ensure the standardization of data acquisition and recording. All ultrasound and MRI measurement indicators follow standard operating procedures (SOP), and key indicators (such as ATT, cIMT) are averaged multiple times to ensure data reliability.
