Abstract: Objective: To explore the intervention effect of "Internet+" three-level linkage management mode on self-management ability and blood glucose index of diabetic patients and family members. Methods: From December 2017 to December 2018, 43 patients and 43 first-degree relatives were conveniently selected from a diabetes diagnosis and treatment center of a tertiary grade A hospital in Gansu province. The intervention time was 18 months with "Internet+" three-level linkage management mode. Before inter vention and at 0, 3, 6, 9, 12 and 18 months after the intervention, the self-management ability scores, blood glucose-related indicators and family members' self-efficacy scores were measured. Results: There were statistically significant differences in the 5 dimensions and total scores of blood glucose monitoring management, diet management, exercise management, handling high/low blood sugar, and foot care in diabetic patients at 6 time points (P<0.05). There were statistically significant differences in the self-efficacy scores of diabetic family members measured at 6 time points (P<0.05). Conclusion: The "Internet +" three-level linkage management mode can improve the self-management ability of diabetic patients and family members, and also provides a certain reference value for the internet management of other chronic diseases.
