Analysis of the reasons and influencing factors of unplanned removal of implantable venous access port in tumor patients

Abstract

Objective To explore the reasons and influencing factors of unplanned removal of implantable venous access port (IVAP) in tumor patients, and analyze its influencing factors, so as to explore the corresponding clinical interventions. Methods A total of 1 029 cases of tumor patients who were implanted IVAP in Zhejiang Cancer Hospital from January 1st, 2009 to December 31st, 2016 were recruited by convenience sampling method. Univariate analysis and Logistic regression analysis were applied to analyze the influencing factors of unplanned port-taking. Results Finally 1 002 tumor patients were recruited excluding patients who died or lost follow-up. Excluding patient's subjective factors, catheter-related blood stream infection (CRBSI) , catheter clamping syndrome, and pain around infusion seat were the main causes of unplanned removal of IVAP. Univariate analysis revealed that there were significant differences in unplanned port removal among patients with different catheterization veins, infection and coagulation function (χ2=15.691, 14.425, 16.732; P<0.001) . Logistic regression analysis showed that internal jugular vein catheterization (OR=8.272) , infection (OR=2.592) and coagulation (OR=2.709) were the main factors. Conclusions Medical staff should strictly control the causes and influencing factors of unplanned removal of IVAP when implanting and maintaining the use of IVAP for patients, so as to prolong the use time of infusion port.
