测量指标:

Outcomes:

指标中文名:

住院期间感染发生情况

指标类型:

主要指标

Outcome:

Nosocomial infection during hospitalization

Type:

Primary indicator

测量时间点:

住院全程(入院至出院)

测量方法:

参照国内外相关诊疗指南及专家共识诊断感染,院内合并感染定义为住院期间新发的感染,或经实验室检查新确诊且符合感染诊断标准的情况。结合患者症状、体征、微生物学检查及影像学结果作出诊断,且诊断结果均由两名高年资医师共同确认。

Measure time point of outcome:

Entire hospitalization (from admission to discharge)

Measure method:

Infections were diagnosed with reference to relevant domestic and international clinical guidelines and expert consensus. Nosocomial co-infection was defined as new-onset infection during hospitalization, or newly confirmed infection meeting diagnostic criteria via laboratory examinations. The diagnosis was made based on patients' symptoms, signs, microbiological tests, and imaging findings, and all diagnoses were jointly confirmed by two senior physicians.

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:

本研究为回顾性观察性研究,数据采集自医院电子病历系统,采集内容包括人口学、疾病、治疗、实验室及感染相关指标,入院 24 小时内完成基线数据采集,实行双人核对与质量控制。数据实行加密存储、去标识化、分级权限管理,全程可溯源,研究结束后保存不少于 10 年。

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

This is a retrospective observational study. Data were collected from the hospital electronic medical record system, including demographic, disease-related, treatment-related, laboratory, and infection-related indicators. Baseline data were collected within 24 hours after admission. Double data entry and verification as well as quality control were implemented. All data were stored encrypted, de-identified, and managed with hierarchical permission. The entire data process was traceable. Data will be preserved for no less than 10 years after study completion.
