Objective:To explore the application effect of integrated mode of medical and nursing in colostomy patients.Methods:Using the convenient sampling method, a total of 60 patients who underwent colostomy in the Second Affiliated Hospital of Wenzhou Medical University from January 2019 to April 2020 were selected as the research objects. The patients who hospitalized from January to August 2019 were included in the control group, and the patients who hospitalized from September 2019 to April 2020 were included in the observation group, with 30 cases in each group. The patients in the control group were treated with routine nursing mode, and the patients in the observation group were treated with integrated mode of medical and nursing. Before discharge, 1, 3 and 6 months after the operation, the status of independent replacement of colostomy bags, scores of the Stoma Self-care Scale-Early Version and the incidence of stoma complications were compared between the two groups.Results:There was no statistically significant difference in the number of patients who changed colostomy bags independently before discharge and 1, 3 and 6 months after the operation between the two group ( P>0.05) . There was no statistically significant difference in the number of cases of periostomy dermatitis, ostomy and mucosal separation and stoma depression between the two groups of patients after surgery ( P>0.05) . The score of the Stoma Self-care Scale-Early Version of the observation group were higher than that of the control group at 3 and 6 months after surgery, and the difference was statistically significant ( P<0.05) . Conclusions:The integrated mode of medical and nursing can improve the self-care ability of patients at 3 and 6 months after the operation , which is worthy of clinical application.
