ObjectiveTo explore the application effect of shared decision-making mode intervention on diet self-management in elderly patients with type 2 diabetes mellitus (T2DM). MethodsA total of 100 elderly patients with T2DM who were admitted to the hospital from January to October 2020 were selected, and they were randomly divided into a control group or an observation group, with 50 cases in each group. Patients in the control group were given a routine dietary health education intervention, based on which patients in the observation group were given an additional shared decision-making mode intervention, and both groups were intervened for 6 months. The mastery of diet management knowledge and blood glucose metabolism indexes levels before and after the intervention and dietary behavior compliance after the intervention were compared between the two groups. ResultsAfter 6 months of intervention, T2DM patients in the observation group scored higher on the diet management knowledge scale and dietary behavior compliance than those in the control group, while the peripheral blood fasting blood glucose, 2-hour postprandial blood glucose, and glycosylated hemoglobin levels of the observation group patients were lower than those of the control group patients (all P＜0.05). There was no statistically significant difference in the above-mentioned indicators (except for the dietary behavior compliance assessment score) between the two groups before treatment (all P＞0.05). ConclusionThe doctor-nurse-patient shared decision-making mode intervention can significantly improve the diet management knowledge mastery and the diabetic dietary behavior compliance in elderly T2DM patients, and it is helpful to improve patients′ blood glucose control effect.
