Marked improvement in HbA1c following commencement of flash glucose monitoring in people with type 1 diabetes

Aims/hypothesis Minimal evidence supports the efficacy of flash monitoring in lowering HbA 1c . We sought to assess the impact of introducing flash monitoring in our centre. Methods We undertook a prospective observational study to assess change in HbA 1c in 900 individuals with type 1 diabetes following flash monitoring (comparator group of 518 with no flash monitoring). Secondary outcomes included changes in hypoglycaemia, quality of life, flash monitoring data and hospital admissions. Results Those with baseline HbA 1c ≥58 mmol/mol (7.5%) achieved a median −7 mmol/mol (interquartile range [IQR] −13 to −1) (0.6% [−1.2 to −0.1]%) change in HbA 1c ( p
