Background: Guidelines endorse a target HbA1c of &lt; 7% for most people with T2D, but less stringent goals (e.g., HbA1c &lt; 8%) and medications with a low risk of causing hypoglycemia are recommended for older patients. We examined the prevalence of potential overtreatment in a global cohort of older patients with T2D.

Methods: DISCOVER is an ongoing, observational study of 15 992 patients with T2D initiating second-line glucose-lowering therapy in 38 countries. HbA1c levels and glucose-lowering therapies were recorded at baseline (initiation of second-line therapy), 6, 12 and 24 months. The analysis includes patients aged ≥ 65 years with a recorded baseline HbA1c level. Insulin, sulfonylureas, and meglitinides are medications associated with risk of hypoglycemia.

Results: Among 3492 older patients, 2110 (60.4%) and 812 (23.3%) had an HbA1c level of &lt; 8% and &lt; 7% at baseline, respectively. The proportions of patients with HbA1c &lt; 7% increased to more than 50% during follow-up (Figure). A third or more of these patients received medications associated with risk of hypoglycemia at baseline and during follow-up.

Conclusions: In this global cohort, including patients from both lower-middle- and higher-income countries, many older patients with good glycemic control (HbA1c &lt; 7%) received medications that are associated with increased risk of hypoglycemia. A more tailored management of hyperglycemia may be needed in this population.
