Background Use of glucose-lowering agents is a cornerstone in combating type 2 diabetes (T2DM). Treatment guidelines have changed significantly over the past decade. We report temporal trends in medication utilization, glycemic control and rate of severe hypoglycemia in T2DM patients at a tertiary referral center in Singapore. Methods We analyzed data of 36 924 T2DM patients seen at Singapore General Hospital from 2007 to 2017. Annual age-, sex- and racially-standardized proportions of patients (a) prescribed with each class of glucose-lowering agent, (b) on various glucose-lowering regimens, and (c) had an HbA(1c) of less than 6%, 6% to less than 7%, 7% to less than 8%, 8% to less than 9%, or 9% or more were estimated using logistic regression. Poisson regression was used to estimate standardized rate of severe hypoglycemia. Results From 2007 to 2017, use of metformin (45.9% to 59.6%) and insulin (24.4% to 57.9%) increased, while utilization of sulfonylureas (52.0% to 44.9%) decreased (all P < 0.001). Utilization of dipeptidyl peptidase-4 inhibitors (1.2% to 31.2%) and sodium-glucose cotransporter-2 inhibitors (0.5% to 7.4%) increased from 2008 to 2017 and 2012 to 2017, respectively (all P < 0.001). More patients were prescribed a combination of insulin and oral agents (17.3% to 46.0%, P < 0.001). The proportion of patients with HbA(1c) of 8% or more increased (33.7% to 36.0%, P < 0.001). Rates of severe hypoglycemia (5.0 to 8.4 per 100 patient-years, P < 0.001) also rose. Conclusion Medication utilization patterns have changed significantly over the past 11 years with a shift towards newer agents. Glycemic control has remained stable, and rate of severe hypoglycemia increased. Further analysis is required before causal relationships can be inferred.
