Abstract: Objective: To analyze the effect of medical-care integrated "cloud ward" management on improving the quality of PICC catheter maintenance and self-management ability of breast cancer patients in intermittent chemotherapy. Methods: 160 breast cancer patients receiving postoperative chemotherapy in Tianjin Medical University Cancer Hospital from November 2016 to June 2017 were recruited by convenience, and the samples were randomly divided into experimental group (with medical-care integrated "cloud ward" management of PICC in intermittent chemotherapy) and control group (only with routine telephone follow-up). The PICC catheter self-management ability and the rates of catheter complications of the two groups were compared before intervention and 6 months later. Results: The rate of catheter infection, mechanical phlebitis, catheter herniation and unplanned extubation in the experimental group was significantly lower than that in the control group (P<0.05). The total score and the scores of each dimension with PICC catheter self-management ability in the experimental group were higher than those in the control group (P<0.05). Conclusion: The medical-care integrated "cloud ward" management model was beneficial to improve the quality of PICC catheter maintenance and the patients, self-management ability, and it is worth further promotion and application.
