Objective  To explore the effect of extended care group combined with "Internet+" on hospital discharge nursing for diabetic foot.

  Methods  Ninety-two patients with diabetic foot who were treated in our hospital were selected as the research subjects. According to the random number table method, they were randomly divided into control group and research group, with 46 cases in each group. The control group used routine nursing, while the study group was given extended nursing group and "Internet+". After three months, the cognitive level outside hospital, nursing effect and self-management ability of the two groups were compared.

  Results  Three months later, the scores of cognitive attitude, nursing method mastery, nursing consciousness, and medication compliance were (9.34±1.64), (9.46±1.73), (9.53±8.46), (8.51±1.34), respectively, and were significantly better than (5.97±1.56), (5.08±1.48), (5.68±8.13), (6.98±1.66), respectively(P < 0.05). The incidences of dry skin (32.61%), cleft palate (2.17%), infection (2.17%), and injury (2.17%) in the study group was significantly lower than 65.22%, 28.26%, 32.61%, and 26.09%, respectively, in the control group(P < 0.05). Before nursing, there was no significant difference in self-management ability score between the two groups (P > 0.05); after nursing, the self-management ability score of the study group was significantly higher than that of the control group (87.36±9.27) vs. (71.68±9.68), P < 0.05.

  Conclusion  Extensive care combined with "Internet+" for diabetic foot patients can effectively improve the cognitive level of patients with diabetic foot disease, and enhance the ability of self-management.
