留置PICC影响因素的Logistic回归分析与研究

Logistic regression analysis and research of related factors on PICC

目的:探讨影响PICC留置的影响因素,为正常留置采取干预措施提供科学依据。方法:采用前瞻性调查的方法,对2008年11月～2011年11月在我院实施PICC患者的相关信息采用PICC临床观察表记录,将我们所关注的30个因素引入多因素Logistic回归模型中进行分析。结果:475例PICC患者中有62例(13.05%)发生非正常拔管,不能达到预期的留置时间,平均留置时间21.48 d。引入分析的30项指标中,多因素Logistic回归分析显示8项指标与非正常拔管的发生有相关性(P<0.05)。结论:PICC导管的留置受多种因素影响,应在PICC置管前后针对相关因素采取有效的预防措施,如加强无菌隔离技术、提高一针穿刺成功率、合理使用抗菌药物和强化局部护理等,有助于长期有效、安全地应用PICC。

Objective ：To investigate the factors related to PICC in order to provide scientific basis for interventions. Methods ： Prospective survey was carried out to investigate the eases from the hospitalized patients in our hospital from November 2008 to November 2011 meanwhile summarize all the information by PICC survey form. Analysis was made to select the significant factors,and the 30 factors selected were brought into multivariate analysis of logistic regression model. Results ：475 eases of PICC abnormal removal occma＇ed in patients with 62 cases （ 13.05% ） , that can not achieved the desired indwelling time. PICC were inserted for a mean duration of 21.48 days. Multivariate regression analysis including eight indicators were found the significant difference with abnor- mal catheter removal（P 〈0.05）. Conclusion：PICC indwelling time was affected by a variety of factors,related factors should be targeted for effective meas- ures. Enhancing germfree isolation and the success rate of one - time puncture, proper use of antibiotics and strengthening the local nursing can apply PICC effect ually and safely for a long period of time.
