- Abstract
Background Little is known about the prevalence of hypoglycaemia in older people with diabetes. However, the HbA1c goal is ≥8% for institutionalised patients with treatments that can cause hypoglycaemia. Purpose We aimed to assess the prevalence of hypoglycaemia with continuous glucose monitoring and to evaluate the link with HbA1C in older institutionalised patients with diabetes taking potentially hypoglycaemia-inducing drugs. Design Prospective, multicentre study carried out in six geriatric care centres in the Côte d'Or region of France between January 2019 and July 2020. Settings, subjects and methods A FreeStyle Libre Pro® (FSLP) was worn for up to 14 days in blinded mode in 42 patients taking at least one potentially hypoglycaemia-inducing antidiabetic drug. Results Two hundred and forty-two hypoglycaemic events were detected in 79% (n = 33) of patients wearing the FSLP. One or more hypoglycaemic event was detected in 100% of patients with HbA1C < 7% and in 79% of patients with HbA1C ≥ 8% (P = 0.02). The time spent in hypoglycaemia was higher in patients with HbA1C < 7% than those with HbA1C ≥ 8% (P = 0.015). Time spent <54 mg/dl was detected in 45% of patients. Conclusions We report a very high prevalence of hypoglycaemia, with a significant proportion of severe hypoglycaemia, in older institutionalised patients with diabetes taking potentially hypoglycaemia-inducing drugs. Having HbA1C < 7% exposes patients to a higher risk of hypoglycaemia, but this risk remains also high in patients with HbA1C ≥ 8%. In this population, continuous glucose monitoring could be considered an effective tool to detect hypoglycemia, which is associated with increased risk of cardiovascular events, falling, fractures, cognitive impairment and mortality.
