Objective To explore influencing factors of catheter maintenance compliance in breast cancer patients with peripherally inserted central catheter (PICC) and the effect of precise nursing.

Methods A total of 301 breast cancer patients with PICC were selected as study objects, univariate and multivariate analyses were used to analyze the influencing factors of catheter maintenance compliance in breast cancer patients with PICC, and receiver operating characteristic (ROC) curves were drawn to evaluate the predictive efficacy of combined diagnosis models of multivariate. Two-color ball method was used to randomly divide the subjects into control group (n=150, implementing routine nursing) and study group (n=151, implementing precision nursing based on routine nursing). Catheter maintenance compliance, self-management ability, nursing satisfaction and occurrence of complications were compared before and after the two groups.

Results Logistic regression analysis showed that age≥ 50 years old (OR=4.148, P=0.021), education level of primary school or below (OR=6.632, P=0.003), senior high school or technical secondary school (OR=5.900, P=0.004), monthly income < 2 000 yuan RMB (OR=6.991, P=0.004), monthly income of 2 000 to 5 000 yuan RMB (OR=4.679, P=0.034), and basic nursing (OR=2.910, P=0.002) were risk factors for low level of catheter maintenance compliance of breast cancer PICC carriers (P < 0.05). The area under the ROC curve (AUC) was 0.870 (95%CI, 0.829 to 0.910), the optimal critical value was 0.269, the sensitivity was 83.7%, the specificity was 74.0%, and the Youden index was 0.577. After intervention, the catheter maintenance compliance of the study group was higher than that of the control group (P < 0.05). After intervention, the score of items of PICC Self-management Scale (CPPSM) and total score in two groups were higher than before intervention, and the study group was higher than the control group (P < 0.05). The nursing satisfaction of the study group was 95.36%, which was higher than 83.33% of the control group (P < 0.05). The incidence rates of phlebitis, catheter blockage, puncture point infection, puncture point bleeding and unplanned extubation in the study group were lower than those in the control group (P < 0.05).

Conclusion Precision nursing can improve catheter maintenance compliance, self-management ability, nursing satisfaction, and reduce the occurrence of complications in breast cancer PICC carriers.
