Abstract: Objective: To explore the effect of caregiver synchronous management on family function and blood glucose control among patients with type 2 diabetes. Methods: Totally 40 hospitalized patients with type 2 diabetes and their caregivers were recruited and received health education, out-patient follow-up and telephone follow-up. Knowledge level and family function of patients and their caregivers and patients' HbA1c level were tested during hospitalization, 3 and 6 months after discharge to compare the difference of different stages. Results: Knowledge level and family function of patients and caregivers and patients' HbA1c all improved significantly after intervention (P<0.05). Repeated measures analysis of variance showed the main time effect of family function and all dimensions of patients and caregivers had statistical significance (P<0.05). Conclusion: Caregiver synchronous management could improve the knowledge level and family function of patients with type 2 diabetes and their caregivers and patients' HbA1c.
