Inadequate glycaemic control and antidiabetic therapy among inpatients with type 2 diabetes in Guangdong Province of China

BACKGROUND: Diabetes mellitus has become epidemic in recent years in China. We investigated the prevalence of hyperglycaemia and inadequate glycaemic control among type 2 diabetic inpatients from ten university teaching hospitals in Guangdong Province, China. METHODS: Inadequate glycaemic control in diabetic patients was defined as HbA1c = 6.5%. Therapeutic regimens included no-intervention, lifestyle only, oral antiglycemic agents (OA), insulin plus OA (insulin + OA), or insulin only. Antidiabetic managements included monotherapy, double therapy, triple or quadruple therapy. RESULTS: Among 493 diabetic inpatients with known history, 75% had HbA1c = 6.5%. Inadequate glucose control rates were more frequently seen in patients on insulin + OA regimen (97%) than on OA regimen (71%) (P < 0.001), and more frequent in patients on combination therapy (81% - 96%) than monotherapy (75%) (P < 0.05). Patients on insulin differed significantly from patients on OA by mean HbA1c, glycemic control rate, diabetes duration, microvascular complications, and BMI (P < 0.01). CONCLUSIONS: This study showed that glycaemic control of type 2 diabetic patients deteriorated for patients who received insulin and initiation time of insulin was usually delayed. It is up to clinicians to move from the traditional stepwise therapy to a more active and early combination antidiabetic therapy to provide better glucose control.
