目的:了解山东省PICC专科护士腔内心电定位技术培训现状及需求，为进一步完善和改进PICC专科护士培训工作提供参考依据。方法:采用便利抽样的方法，于2019年7月7—23日，选取山东省PICC专科护士共903名，通过自制的山东省PICC专科护士一般资料调查表以及腔内心电定位技术培训需求问卷对其进行调查。结果:40.75%（368/903）的PICC专科护士参加过腔内心电定位技术培训；84.27%（761/903）的PICC专科护士认为需要进行腔内心电定位技术培训；PICC专科护士对腔内心电定位技术培训的各项内容需求均分均>4.67分，其中理论课程需求得分最高的为导管头端位置与心电图P波关系的判断（4.80 ± 0.47）分，操作课程需求得分最高为腔内心电定位技术引导PICC置管操作（4.74 ± 0.55）分；培训模式需求方面：94.24%（851/903）的护士希望通过腔内心电定位技术的培训达到提高临床护理实践能力的目标，静脉治疗专科学术会议为主要希望的培训形式（76.85%，694/903）。多元线性回归分析显示，置管年限、工作岗位以及是否了解腔内心电定位技术是PICC专科护士对腔内心电定位技术培训需求的影响因素（n t = -3.73、3.12、-3.63，均n P<0.05）。n 结论:腔内心电定位技术的培训开展率较低，但PICC专科护士对腔内心电定位技术有较高的培训需求，管理者应重视腔内心电定位技术的培训，制订有针对性的培训方案，进一步提高PICC专科护理队伍的临床实践能力。“,”Objective:To understand the current situation and demand of intracavity electrocardiographic positioning technique training for PICC specialist nurses in Shandong Province, and provide a reference for further improving and improving the training of PICC specialist nurses.Methods:From July 7-23, 2019, a total of 903 PICC specialist nurses in Shandong Province were selected by the convenience sampling method. The nurses were investigated by the self-made general information questionnaire of PICC specialist nurses in Shandong Province and the training demand questionnaire of intracavity electrocardiographic positioning technique.Results:40.75% (368/903) PICC specialist nurses had participated in intracavity electrocardiographic positioning technique training; 84.27% (761/903) PICC specialist nurses thought it necessary to conduct intracavity electrocardiographic positioning technique training. PICC specialist nurses had various training on intracavity electrocardiographic positioning technique, the average content requirements were all above 4.67 points. The highest score of theoretical training content was the judgment of the relationship between catheter tip position and electrocardiogram P wave (4.80 ± 0.47), and the highest score of operation training content was the intracavitary electrocardiography guided PICC catheterization (4.74 ± 0.55). 94.24%(851/903) PICC specialist nurses hoped to achieve the goal of improving clinical nursing practice ability through intracavity electrocardiographic positioning technique training. Intravenous therapy specialist academic conference was the main hoped training form(76.85%, 694/903). Multiple regression analysis showed that the number of years of catheterization, job position and understanding of the technology were the influencing factors of PICC specialist nurses′ training needs for intracavity electrocardiographic positioning technique (n t = -3.73,3.12, -3.63, all n P<0.05).n Conclusions:The training rate of intracavity electrocardiographic positioning technique was low, but PICC specialist nurses had higher training requirements for intracavity electrocardiographic positioning technique. Managers should pay attention to the training of intracavity electrocardiographic positioning technique, and develop targeted training programs to further improve the clinical practice capabilities of the PICC specialist nursing team.
