Flash glucose monitoring is known to reduce hypoglycaemia events but little evidence supports its efficacy in reducing HbA1c in type 1 diabetes. In this issue, Tyndall and Stimson et al (https://doi.org/10.1007/s00125-019-4894-1) prospectively assessed the effect of introducing flash monitoring in a diabetes centre. Compared with the total type 1 population, flash monitor users were typically younger, more affluent and had lower baseline HbA1c. There was a 49% increase in the proportion achieving a target HbA1c of <58 mmol/mol (<7.5%) and a >50% decrease in the proportion with an HbA1c of >75 mmol/mol (>9.0%). Flash monitor use was also associated with a reduction in admissions for diabetic ketoacidosis. Self-reported hypoglycaemia increased with flash monitoring use, although this was likely to be a consequence of greater recognition of events. User satisfaction was extremely high; however, there was an increase in anxiety and depression symptoms. Taken together, the authors conclude that these findings suggest that flash monitoring is capable of reducing HbA1c in a ‘real-world’ setting.
