目的 探讨广东省基层护士经外周静脉置入中心静脉导管（peripherally inserted central catheter，PICC）维护培训的方法和成效。方法 2018年—2020年，广东省护理学会静脉治疗专业委员会构建“省-市-地”三级联动帮扶架构，整合市级学会和当地医院的静脉治疗专业教育培训资源，向省内2 139名基层护士开展PICC维护的培训。培训前后，进行理论和操作考核；培训后，调查护士对培训的满意度；调查培训前、后1年内12所基层医院患者PICC相关并发症和往返医院费用情况，以及对护士工作的满意度。结果 培训后，护士的理论、操作考核成绩高于培训前（P<0.05），超过97%的护士对培训表示满意；培训后1年内，12所县级人民医院上报PICC相关并发症的总体发生率由4.08%降至1.98%（χ²=9.206，P=0.002）；基层PICC患者用于往返医院维护导管的平均交通费用由（380.00±16.35）元降至（180.00±10.18）元（t=214.479，P<0.001），95%及以上的患者对维护服务表示满意。结论 三级联动推进基层护士PICC维护培训，提高了基层护士的PICC的理论、操作水平及临床服务水平。

Objective To describe the methods and explore the effect of basic venous catheter maintenance training in primary nurses in Guangdong Province. Methods From 2018 to 2020，Intravenous Therapy Professional Committee of Guangdong Nursing Society has constructed a three-level linkage support structure of “provincial-city-local”，which integrated the teaching and training resources of static therapy specialty of municipal institutes and local hospitals. Training of venous catheter maintenance was carried out among 2 139 primary nurses in Guangdong Province. Before and after the training，the nurses who participated in the training were evaluated in theory and operation. After training，nurses’ satisfaction with training was investigated. The PICC-related complications and patients’ transportation costs were surveyed within one year after training. Results After training，the level of theoretical knowledge and operational skills of primary nurses improved compared with that before training（P<0.05），and more than 97% of the nurses were satisfied with training. One year after the training，the overall incidence of PICC-related complications reported by 12 county-level people’s hospitals decreased from 4.08% to 1.98%（χ²=9.206，P=0.002）. The average transportation cost of primary patients with catheter to and from hospital for catheter maintenance decreased from（380.00±16.35） yuan to（180.00±10.18） yuan（t=214.479，P<0.001），and their satisfaction rate with maintenance service was above 95%. Conclusion The three-level linkage promoted PICC maintenance training for primary nurses，and improved the theory，operation level and clinical service level of primary nurses on PICC.
