Chinese Endocrinologists Health Education Study

The primary objective is to determine whether a 1-week intensive experiential training in T2DM management for MMC endocrinologists has a positive effect on patients' HbA1c control rate (percentage of patients achieving HbA1c <7.0%) after 6-month management. The secondary objective is to explore the effect of intensive experiential training on other metabolic parameters, patients' quality of life and endocrinologists' prescribing habits after 6-month and 12-month management.

In the first phase (Phase I), about 200 eligible endocrinologists from National Metabolic Management Centers (MMC) (one endocrinologist in each center) will be randomized (1:1) into two groups. Intensive training group will receive a 1-week intensive experiential training in the MMC leading center (Ruijin Hospital) for T2DM management, and control group will receive regular MMC working training. In the second phase (Phase II) , each endocrinologist will be required to manage a certain number of T2DM patients (n≈10). The total number of patients in the intensive training group and the control group will be approximately 1000:1000. Metabolic parameters including weight, body mass index (BMI), waist circumference, hip circumference, glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), postprandial plasma glucose (PPG), fasting and postprandial insulin, blood pressure and lipid levels will be measured. Furthermore, the change of patients' quality of life and endocrinologists' prescribing habits will be evaluated.
