Flash glucose monitoring (FGM): A clinical review on glycaemic outcomes and impact on quality of life
2020
Abstract Flash glucose monitoring (FGM) is widely accepted as an alternative means to conventional finger prick test for measuring glucose level in individuals with diabetes mellitus. In this clinical review, we endeavour to draw all available clinical evidence on the usage and efficacy of FGM from research trials and observational studies in real-world settings. We aim to explore its clinical efficacy and impact on quality of life (QoL) in the diabetic population. In terms of clinical outcomes, use of FGM is associated with a significant reduction in glycated haemoglobin A1c (HbA1c) level, notably in patients with suboptimal glycaemic control prior to commencement of FGM and reduction in time spent in hypoglycaemia. FGM demonstrated non-inferiority in device accuracy when compared to other well-established CGMs available in the market. Patients have reported improved QoL and treatment satisfaction measured by validated objective scores after consistent use of FGM. This results in a positive impact on patient psychosocial wellbeing and ultimately enhances patient compliance and optimisation of glycaemic control. Evaluation of QoL and patient reported outcome measures (PROMs) will require a standardised approach to allow comparability of the results and evidence.
