摘要导尿管相关性尿路感染（CAUTI）是指患者留置导尿管后，或者拔除导尿管48 h内发生的泌尿系统感染。发生CAUTI会加重患者病情，导致患者住院时间延长，增加医疗成本及患者经济负担，严重时危及患者生命安全。亚太地区感染控制学会（APSIC）召集亚太地区感染预防与控制专家成立工作组推出了《APSIC预防导尿管相关性尿路感染指南》[ APSIC guide for prevention of catheter associated urinary tract infections（CAUTIs），简称"APSIC指南"]，内容涉及留置导尿患者CAUTI的预防和管理，涵盖患者导尿管置入、维护和拔管整个过程，APSIC指南具有可操作性和指导性。本文从CAUTI危险因素、诊断、预防方案的制定、监测和预防方案的实施等方面对APSIC指南进行解读，以期为临床医务人员预防CAUTI提供科学的指引。

abstractsCatheter associated urinary tract infection (CAUTI) refer to urinary system infections that occur after the insertion of a urinary catheter or within 48 hours after its removal. CAUTI exacerbate patient conditions, prolong hospital stays, increase medical costs and economic burdens on patients, and can be life-threatening in severe cases. The Asia Pacific Society of Infection Control (APSIC) convened a working group of infection prevention and control experts from the Asia-Pacific region to publish the APSIC guideline for prevention of catheter associated urinary tract infections (CAUTIs) (referred to as the "APSIC Guideline"). This guideline encompasses the prevention and management of CAUTI in patients with indwelling catheters, covering the entire process from catheter insertion, maintenance, to removal, and are characterized by their practicability and directive nature. This article interprets the APSIC Guideline from aspects such as risk factors of CAUTI, diagnosis, development of prevention strategies, monitoring, and implementation of prevention plans, aiming to provide scientific guidance for clinical healthcare professionals in preventing CAUTI.
