Abstract:

Objective To establish an expert consensus on the management of mini-midline catheters（hereinafter referred to as the ‘consensus’） to guide nurses in standardizing the insertion and maintenance of mini-midline catheters. Methods Evidence was systematically retrieved，scientifically evaluated，and synthesized using evidence-based methods to draft the initial version of the consensus. From December 2023 to July 2024，totally 2 rounds of expert correspondence and 2 rounds of expert panel discussions were conducted to revise the content，resulting in the final version. Results There were 17 experts from tertiary A general hospitals in Beijing，Shanghai，Hunan，Hubei，Sichuan，Jiangsu，Hainan，Guangxi Zhuang Autonomous Region，and Shandong participating in the consultation，with a 100% response rate. In the 2 rounds of expert correspondence，the authority coefficients were 0.947 and 0.962，respectively. The mean importance scores of all items exceeded 4.00 points. The coefficients of variation（CV） were 0-0.32（first round） and 0-0.15（second round）. Kendall's concordance coefficients were 0.097 and 0.101 （both P<0.001）. The consensus covers 11 sections，including definition，indications，contraindications，qualification training，pre-insertion preparation，catheter insertion，catheter use，catheter maintenance，catheter removal，prevention and management of common complications，and health education. Conclusion The Consensus demonstrates scientific rigor and comprehensively addresses key procedures before，during，and after the insertion of mini-midline catheters，providing actionable guidance for nurses in catheter insertion and maintenance.

摘要：

目的 形成迷你中等长度导管管理专家共识（以下简称“共识”），以指导护士规范迷你中等长度导管的置入及维护。方法 运用循证方法系统检索、科学评价和汇总证据，形成“共识”初稿。于2023年12月—2024年7月通过2轮专家函询以及2轮专家论证会，对“共识”内容进行修订，形成终稿。结果 17名来自北京市、上海市、湖南省、湖北省、四川省、江苏省、海南省、广西壮族自治区、山东省三级甲等综合医院的专家参与函询，其积极系数为100%。2轮专家函询中，专家的权威系数分别为0.947、0.962；条目的重要性评分均数均>4.00分；变异系数分别为0~0.32、0~0.15；肯德尔和谐系数分别为0.097、0.101（均P<0.001）。“共识”涵盖迷你中等长度导管的定义、适应证、禁忌证、资格培训、置管前准备、导管置入、导管使用、导管维护、导管拔除、常见并发症预防及处理、健康教育11个部分。结论 “共识”具有科学性、严谨性，覆盖迷你中等长度导管置管前、中、后的各个关键环节，可为护士置入和维护迷你中等长度导管提供指导。
