Objective To analyze the application value of tertiary hospital and community health integrated management model in the foot care of diabetic patients. Methods A total of 180 cases of patients with diabetes mellitus admitted to the First Affiliated Hospital of Henan University from January 2018 to June 2018 were selected for the study and were divided into observation group and control group according to the random number table method, with 90 cases in each group.Control group was given routine management, and observation group adopted tertiary hospital and community health integrated management model, and they were intervened for 6 months.The episode frequency, hospitalization frequency, hospital stay, hospitalization expenses, and fasting blood glucose(FBG), postprandial 2 h blood glucose(P2BG) and glycosylated hemoglobin(HbA1c), foot care effects [Chinese version of Nottingham assessment of functional foot-care(CNAFF)], self-management ability scale(SDSCA) score, diabetes specific quality of life scale(DSQL) score before and after intervention were recorded in the two groups. Results The episode frequency, hospitalization frequency, hospital stay and hospitalization expenses in observation group were lower than those in control group.The FBG, P2BG, and HbA1c in observation group after intervention were lower than those in control group, and the differences were statistically significant(P<0.05). The good foot care rate at 6 months after intervention in observation group was higher than that in control group, and the difference was statistically significant(P<0.05). The SDSCA scores in observation group were higher than those in control group at 1 month, 3 months and 6 months after intervention, while the DSQL score was lower than that in control group, and the differences were statistically significant(P<0.05). Conclusions Tertiary hospital and community health integrated management model for patients with diabetes mellitus, and it can significantly improve the blood glucose level, improve the quality of foot care, quality of life and self-management ability.Therefore it is worthy of clinical promotion and practice.
