Objective To explore the application of Internet + nursing model in PICC catheter maintenance of discharged tumor patients.

Methods One hundred patients with PICC were divided into on-site maintenance group under Internet + nursing model and return-to-hospital maintenance group, with 50 cases in each group.The return-to-hospital maintenance group received return-to-hospital maintenance, and the on-site maintenance group received on-site maintenance.The differences of PICC catheterization knowledge score, atopic dermatitis, catheter ejection, catheter blockage, puncture site infection, puncture site bleeding and other complications, PICC indenture time and nursing satisfaction were compared between the two groups.

Results There was no significant difference in the incidence of atopic dermatitis, catheter prolapse, catheter blockage, puncture site infection and puncture site bleeding between the two groups (P>0.05).The number of regular maintenance in the on-site maintenance group was significantly better than that in the return-to-hospital maintenance group (P < 0.01), and the indwelling time of PICC was significantly longer than that of the return-to-hospital maintenance group (P < 0.01).The incidence of complications in the on-site maintenance group was significantly lower than that in the return-to-hospital maintenance group (P < 0.05).The satisfaction of patients and their families in the on-site maintenance group was 95%, higher than that in the return-to-hospital maintenance group (78%) (P < 0.01).The incidence of unplanned extubation was 4% in the on-site maintenance group, lower than that of 20% in the return-to-hospital group (P < 0.05).

Conclusions Internet + nursing model has good effect in PICC catheter maintenance of discharged tumor patients, and it is worth promoting.
