临床护士预防PICC导管相关感染的知信行现状及影响因素分析

目的：探讨临床护士对预防PICC导管相关感染的知信行现状，并分析其影响因素。方法：采用便利抽样法于2019年10月选取天津市5家医院215名临床护士，使用自行设计的知信行调查问卷进行调查，采用多重线性逐步回归分析其影响因素。结果：临床护士预防PICC导管相关感染的知信行总分为（90.86±5.23）分、知识（17.36±3.00）分、态度（24.13±1.83）分、行为（49.37±2.36）分；多重线性逐步回归分析结果显示，学历、是否为PICC专科护士、是否接受过PICC-CRI的知识培训是知识得分的主要影响因素（P<0.05）；是否为PICC专科护士、是否接受过中心静脉导管更换敷料的考核是影响预防态度的主要因素（P<0.05）。结论：临床护士预防PICC导管相关感染的知信行水平总体良好，其中预防PICC导管相关感染的态度和行为得分较高，但预防知识得分较低，建议加强相关理论知识的学习和培训，提高护士预防感染相关认知。

The investigation of knowledge,attitude and practice of clinic nurses inpreventing PICC catheter-related infections and its influencing factors

Objective: To investigate the current status of knowledge, attitude and practice of clinical nurses in preventing PICC catheter-related infections, and to analyze the influencing factors. Methods: In October 2019, 215 clinical nurses from 5 hospitals in Tianjin were selected by convenience sampling method. The self-designed questionnaire for knowledge, attitude and practice was used to conduct the survey. The multiple linear stepwise regression was used to analyze the influencing factors. Results: The total scores of knowledge, attitude and practice on prevention of PICC catheter-related infections were 90.86 ± 5.23, among which the score of knowledge was 17.36 ± 3.00, the score of attitude was 24.13 ± 1.83, and the score of practice was 49.37 ± 2.36. The results of multiple linear stepwise regression analysis showed that education background, PICC specialist nurses, and knowledge training were the main influencing factors of knowledge scores(P<0.05); PICC specialist nurses, PICC dressing change assessment were the main factor affecting attitude(P<0.05). Conclusion: The nurses’ knowledge, attitude and practice level on the prevention of PICC catheter-related infections were generally good. The scores of nurses’ attitudes and practice were high, but the scores of knowledge was low. It is recommended to strengthen the learning and training of relevant theoretical knowledge to improve infection prevention.
