Risk factors of catheter-related infection and coping strategies about power peripherally inserted central catheter in patients with breast cancer

Objective To discuss risk factors of catheter-related infection and coping strategies about power peripherally inserted central catheter (POWER PICC) in patients with breast cancer, and to provide the evidence-based nursing basis for standard operational procedure of POWER PICC. Methods A total of 323 patients with breast cancer underwent chemotherapy by three directional valve PICC, and a total of 322 patients did by POWER PICC. Risk factors of catheter-related infection were analyzed by univariate analysis and logistic multiple regression analysis. Results The catheter-related infection rate of POWER group was higher than that of three directional valve group[11.49% (37/322) vs 5.26% (17/323); χ2=8.152, P<0.01]. Four risk factors of catheter-related infection in the POWER group were screened by univariate analysis, including material of catheter, position of puncture, treatment for wound surface and sort of connector. Unconditional multiple analysis was conducted, regarding bacterial colonization as dependent variable and other factors as independent variable. The result demonstrated that individual care strategy for PICC was the risk factor of catheter-related infection of POWER PICC. Conclusions Understanding of the property of POWER PICC material and applying individual care strategy to enhance advantage and avoid disadvantage can prevent catheter-related infection of POWER PICC effectively.
