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:回顾性提取医院 2024 年 1 月 —2025 年 7 月电子病历系统(his)、实验室信息系统及影像系统中的历史诊疗数据,不涉及前瞻性招募与新增检查。 采集内容:人口学资料(性别、年龄)、临床诊断(ICD-10 编码)、实验室指标(CRP、ESR、WBC 等)、影像学结果、合并症与用药史。 采集方式:非干预性回顾性查阅,通过病案检索筛选符合纳入 / 排除标准的病例,由 2 名研究者独立提取数据并交叉核对。 数据管理:数据去标识化处理,研究结束后保存 5 年以上,仅用于本研究,不对外共享。 伦理与安全:已通过医院伦理委员会审查(伦理号:2026040K),符合个人信息保护与医学研究伦理规范。

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

Data source:Retrospective extraction of historical medical data from the hospital’s electronic medical record system (HIS), laboratory information system and imaging system between January 2024 and July 2025. No prospective recruitment or additional examinations were involved.Data collection contents:Demographic data (gender, age), clinical diagnosis (ICD-10 codes), laboratory indicators (CRP, ESR, WBC, etc.), imaging findings, comorbidities and medication history.Data collection method:Non-interventional retrospective review. Cases meeting the inclusion/exclusion criteria were identified through medical record retrieval. Data were independently extracted by two researchers and cross-checked.Data management:Data were de-identified. Data will be stored for more than 5 years after study completion, used only for this study, and not shared externally.Ethics and safety:This study was approved by the Hospital Ethics Committee (Ethics No.: 2026040K) and complies with personal information protection and ethical norms for medical research.
