摘要目的：对导尿管相关尿路感染预防指南进行评价，为临床导尿管相关标准化护理方案及指南实践的质量改进方案制订提供重要依据。方法检索国内外数据库和指南网，按照纳入排除标准筛选指南。描述性分析指南的名称、发表年份、发表机构、指南制定方法、参考文献数目等一般特征资料。使用指南研究与评价工具AGREE Ⅱ对纳入指南的质量进行评价。结果纳入5部指南，1部语种为中文、其他4部均为英语。质量评价结果显示5部指南清晰性领域得分最高，平均分为72％；其次分别为独立性领域（64％）、目的和范围领域（62％）、严谨性领域（53％）、应用性领域（46％）；参与人员领域最差（44％）。其中，3位评价者一致认为美国疾病预防控制中心2010年发布的Guideline for Prevention of Catheter-Associated Urinary Tract Infections 2009为推荐指南，另外建议有3部可经过相应修订后使用。结论导尿管相关尿路感染预防指南质量参差不齐，临床实践中指南的确定及选择应根据方法学质量评价结果并参考临床条件、现状等最终选取。
