研究目的:

(1)描绘老年流感患者常规实验室指标变化。通过回顾性分析住院患者的实验室检查结果,总结老年流感患者疾病变化特征。 (2)探索实验室指标与临床结局之间的潜在关联。为老年流感患者的风险分层和预后评估提供依据。  

Objectives of Study:

(1) Describe the changes in routine laboratory indicators of elderly influenza patients. By retrospectively analyzing the laboratory test results of hospitalized patients, summarize the characteristics of disease progression in elderly influenza patients.(2) Explore the potential associations between laboratory indicators and clinical outcomes to provide a basis for risk stratification and prognosis assessment in elderly influenza patients.

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:

研究数据采集包括回顾性临床资料提取和恢复期随访检测资料收集两部分。回顾性资料由经过培训的研究人员依据统一病例报告表,从医院电子病历系统中提取人口学信息、基础疾病、临床症状和体征、治疗经过、实验室检查结果及临床结局等资料;恢复期随访检测结果由医院检验信息系统导出。所有研究对象均使用唯一研究编号进行去标识化处理,分析数据库不包含姓名、身份证号、联系电话等直接身份识别信息。数据录入后由研究人员对关键变量进行核对,并进行缺失值检查、逻辑核查和异常值复核。完成数据清理后锁定数据库,锁库后原则上不再修改。纸质知情同意书及病例报告表由专人保管于上锁文件柜中,电子数据采用加密文件保存,仅限课题组授权人员访问。

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

Study data collection will include retrospective clinical data extraction and convalescent follow-up laboratory data collection. Retrospective data will be extracted from the hospital electronic medical record system by trained investigators using a standardized case report form, including demographic information, comorbidities, clinical symptoms and signs, treatment, laboratory results and clinical outcomes. Convalescent follow-up laboratory results will be obtained from the hospital laboratory information system. Each participant will be assigned a unique study ID, and direct identifiers such as name, identification number and telephone number will not be included in the analysis dataset. Key variables will be checked, and missing values, logical errors and outliers will be reviewed before database lock. Paper informed consent forms and case report forms will be stored in locked cabinets, and electronic data will be stored in password-protected files accessible only to authorized study staff.
