GLucose Monitoring Programme SingaporE, Phase 2 (GLiMPSE2)

Many with type 2 diabetes (T2D) remain sub-optimally controlled. Structured programmes requiring dietary and lifestyle intervention have been shown to improve control but are time-and labour-intensive. The role for self-monitoring of blood glucose with capillary blood glucose (CBG) readings is uncertain. The use of flash glucose monitoring (FGM) with education may effect improvements in awareness and self-management behaviour and hence glycaemic control. The investigators aim to compare the effects of FGM versus CBG fingersticks in the context of a structured education programme over a 6-month period in adults with type 2 diabetes. 200 adults (\>21y) with sub-optimally controlled T2D (7.5-10%) on either diet-controlled, oral glucose lowering drugs or background insulin will be enrolled and randomised into the intervention arm (FGM and education) or control arm (capillary glucose fingersticks and education). The intervention arm will monitor glucose using FGM continuously for 6 weeks and intermittently thereafter up to 24 weeks. The control group will monitor glucose using CBG fingersticks up to 24 weeks. During the intervention period(0-24w), both arms will undergo the same schedule of visits (-2w, 0w, 8w, 16w, 24w) and 6 education sessions. Both groups will be followed up at weeks 38 and 52. Primary outcome is HbA1c change from baseline at 24 weeks. This study will provide novel data on the use of FGM versus CBG in Type 2 diabetes and its impact on glycaemic control.
