Objective To explore the effectiveness of using educational robots for continuing care in empty-nest older patients with diabetes.Methods A total of 118 empty-nest older patients with diabetes were selected as the research subjects, with 59 patients in the observation group and 59 patients in the control group based on their admission time. The control group received conventional continuing care, while the observation group received continuing care using educational robots. After 6 months, the blood glucose-related indicators, self-management behavior scores, and diabetes-specific quality of life scores were compared between the two groups. Results At the 6-month follow-up after discharge, the observation group showed significantly better scores in self-management behavior, blood glucose-related indicators, and diabetes-specific quality of life compared with the control group (all P<0.05). Conclusion The application of educational robots for continuing care in empty-nest older patients with diabetes can enhance their self-management abilities, improve blood glucose indicators, and enhance their quality of life.
