Diabetes in the older person is challenging as it often in the context of frailty. In the frail individual the consequences of hypoglycaemia outweigh the benefits of avoiding hyperglycaemia. The American Diabetes Association (ADA) provides standards of care for older adults, including glycaemic targets prioritising safety and quality of life. This audit assessed adherence to ADA guidelines on glycaemic targets in older adults with diabetes using continuous glucose monitoring (CGM) devices. Older adults (aged >65 years) with diabetes using CGM devices attending our service were included. Clinical information, glycated haemoglobin (HbA1c), and CGM metrics were gathered retrospectively from medical records and the DEXCOM CLARITY online platform. Data collection occurred between January and March 2025. A total of 123 individuals were included. Median age was 72 years (IQR = 10), 64 (52%) were male, and 76 (61.8%) had type 1 diabetes. Mean duration of diabetes was 31.3 years (±15.4). Mean HbA1c was 67.4 mmol/mol (±13.7), with 55.7% achieving the ADA target of <64 mmol/mol. With regard to CGM metrics, 56 (45.5%) had time in range >50%; 68 (55.25%) had time below range <1%, 121 (98.4%) had time above range level 1 <50%; and 31 (25.2%) had time above range level 2 <10%. Although over half of older adults met ADA HbA1c targets, CGM data revealed ongoing exposure to hypo- and hyperglycaemia. These findings highlight the importance of CGM in individualising diabetes care in older adults and support broader access to CGM alongside multidisciplinary input to optimise safety and quality of life.
