Objective： Although clinicians, nurse specialists, pharmacists, and nutritionists expend significant time and resources attempting to optimize care for patients with diabetes, the optimal approach to improving diabetes care remains uncertain. We aimed to assess the effects of diabetes education team on glycated haemoglobin (HbAlc). Methods: The present study was a matched case-control study using the propensity score on the effectiveness of reducing HbAlc between education group and control group in Korean patients with type 2 diabetes. We included 27 pairs of patients hospitalized between June 2014 and September 2016. The HbAlc values measured at baseline, 3 months, and 6 months were compared between two groups. Results： The education group showed an improvement in the HbAlc level compared to the control group at 3 months (6.3 ± 2.3% vs 9.5 ± 4.0%，P= 0.020) and at 6 months (7.5 ± 1.5% vs 9.6 ± 3.0%，P = 0.106). There was a significant difference in Changes of mean HbAlc from baseline at 3months between two groups (-35.7 ± 26.1 vs -9.1 ± 20.5%，P=0.013). Conclusion： Using diabetes education team was advantageous for improving glucose control in patients with type 2 diabetes and may help these patients to optimize glycemic control in clinical practice.
