目的 了解成都市肿瘤科医护人员经外周静脉留置中心静脉导管术（PICC）认知现状，为今后开展PICC相关知识培训提供科学依据。 方法 2009年12月－2010年1月采用自行设计的问卷对成都市5家三甲医院的肿瘤科医护人员309名（医生134名，护士175名）进行PICC认知态度现状调查。 结果 成都市三甲医院肿瘤科医护人员PICC认知呈中等偏低的水平，护士PICC知识的掌握高于医生（P＜0.05），护士PICC态度得分优于医生（P＜0.05）。94.84%的医护人员知道PICC技术；只有8.38%的肿瘤科医护人员接受过PICC专业培训。不同文化程度、年龄、工龄、职业与PICC认知之间的差异存在统计学意义（P＜0.05）。 结论 三甲医院肿瘤科医护人员对PICC技术有一定的了解，但总体认知仍有待提高，需加强PICC相关知识培训，进一步提高医护人员PICC认知水平，以利于肿瘤专科开展PICC技术，促进肿瘤护理的专业化发展。
