Outcomes:

指标中文名:

给药7天后感染是否改善

指标类型:

主要指标

Outcome:

Infection improvement after 7 days of treatment

Type:

Primary indicator

测量时间点:

给药七天后

测量方法:

总体临床反应基于临床、实验室、微生物学及影像学综合标准进行定义,符合任意一项标准即可认为感染改善。临床改善包括感染相关体征和症状的缓解或消除,例如退热(体温≤37.3°C)及生命体征稳定。实验室反应定义为炎症标志物(白细胞计数、中性粒细胞百分比、C反应蛋白、降钙素原)较基线水平下降或恢复正常。微生物学反应根据培养结果分为根除、假定根除或持续存在。影像学反应定义为感染相关影像学表现改善或无进展。

Measure time point of outcome:

After 7 days of treatment

Measure method:

Overall clinical response was defined based on a composite of clinical, laboratory, microbiological, and radiological criteria. Infection improvement was considered to have occurred if any one of the following criteria was met. Clinical improvement was defined as resolution or alleviation of infection-related signs and symptoms, such as defervescence (body temperature ≤37.3°C) and stabilization of vital signs. Laboratory response was defined as a decrease from baseline or normalization of inflam

利用医院病历系统回顾性检索所有使用替加环素、依拉环素或奥马环素的患者,收集相关患者的信息,并收集使用依拉环素或奥马环素时间超过72小时的血样,不进行干预及随访。收集患者的临床资料包括: 1)患者人口学资料:性别、体重、年龄等; 2)感染类型及菌株:感染部位、检测出的感染菌株、是否为耐药菌、是否合并感染; 3)血常规、肝肾功等实验室检查项目:如红细胞、白细胞、丙氨酸氨基转移酶、天冬氨酸氨基转移酶、碱性磷酸酶(ALP)、纤维蛋白原(FIB)、纤维蛋白降解产物(FDP)总胆红素(TBIL)、白蛋白(ALB)、血肌酐(CREA)、肌酐清除率(CLcr)、C反应蛋白、降钙素原等; 4)有效性和安全性:是否临床改善、出院、转院或死亡时间、报告的可能的不良事件; 5)合并用药:其它抗菌药物或影响代谢酶功能的药物; 6)依拉环素或奥马环素用药信息及采血时间:依拉环素或奥马环素的给药时间与采血时间,以及给药剂量和间隔。

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

A retrospective search of the hospital medical record system was conducted to identify all patients who had received tigecycline, eravacycline, or omadacycline. Relevant patient information was collected, and blood samples were obtained from patients who had received eravacycline or omadacycline for more than 72 hours. No intervention or follow-up was performed. The clinical data collected included the following:Demographic data: sex, weight, age, etc.Type of infection and causative strain(s): site of infection, detected strain(s), whether the strain was drug-resistant, and presence of co-infection.Laboratory tests including complete blood count, liver and renal function: red blood cell count, white blood cell count, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), fibrinogen (FIB), fibrin degradation products (FDP), total bilirubin (TBIL), albumin (ALB), serum creatinine (CREA), creatinine clearance (CLcr), C-reactive protein, procalcitonin, etc.Efficacy and safety: whether clinical improvement occurred; discharge, transfer to another hospital, or time of death; and reported possible adverse events.Concomitant medications: other antimicrobial agents or drugs affecting metabolic enzyme function.Eravacycline or omadacycline administration details and blood sampling times: administration times and blood sampling times for eravacycline or omadacycline, as well as the dose administered and dosing interval.
