ABSTRACT
AIMS: We aimed to evaluate both glycaemic parameters and patient-reported outcomes in patients prescribed FGM based on the local criteria at our institution. METHODS: This retrospective observational study included patients agedâ¯>â¯18â¯years with a diagnosis of type 1 diabetes mellitus (T1DM) who were prescribed FreeStyle Libre FGM (nâ¯=â¯90). Quantitative data on glycaemic parameters was collected pre- and post-initiation of FGM in addition to patient-reported outcome measures (PROMs). The primary outcome was change in pre- and post-FGM levels of glycosylated haemoglobin (HbA1C). RESULTS: There was a mean reduction in HbA1c of -7.29⯱â¯10.76â¯mmol/mol (pâ¯<â¯0.001, CI95% 4.94-9.64) sustained to the latest reading. There was also a mean reduction in the number of hypoglycaemic episodes per week of 3.20 (percentage reduction 51.86%, pâ¯<â¯0.001, CI95% 1.64-4.77). A significant improvement in quality of life scores was noted in all five domains of the abbreviated DDS between before and after starting FGM (pâ¯<â¯0.001). Key themes highlighted in inductive content analysis include 'life-changing', 'positive experience', and 'convenient'. CONCLUSION: Flash glucose monitoring is associated with significant improvement in HbA1c to a mean follow-up of 4.6â¯months. Additionally, patients reported positive experiences of FGM with significant improvement in all aspects of a focussed Diabetes Distress Scale.
