96-LB: Effectiveness of FreeStyle Libre Flash Glucose Monitoring System Observed in Real-World, Chart Review Study in Austria, in Adults with Type 2 Diabetes
2019
This retrospective chart review study evaluated the effectiveness of the FreeStyle Libre Flash Glucose Monitoring System TM when used by adults with type 2 diabetes (T2DM) as their standard of care in a real-world setting. This study aimed to determine the effect of FreeStyle Libre when used for between 3 months to 6 months on HbA1c. The study population included adults on a basal-bolus insulin regimen for at least 1 year who had been using FreeStyle Libre regularly for at least 3 months (either self-funded or prescribed) and with HbA1c between 8.0 and 12.0% (64 to 108 mmol/mol). Pregnant patients were excluded, as were patients on dialysis. A total of 92 records from insulin using patients with T2DM from 6 hospital sites in Austria were included in this chart review. On average, HbA1c was 8.8±0.8% (72.2±8.9 mmol/mol), prior to FreeStyle Libre use, age was 64.4±9.7 years, BMI was 30.8±5.5 kg/m 2 and average duration of insulin use 7.6±5.6 years (mean±SD), 79.3% of patients were on oral antidiabetic medications (metformin, TZD, DPP-4 or SGLT) and 54.3% were male. CVD and renal complications were reported by 34.8% and 27.2% of patients, respectively. HbA1c results were recorded between 91 to 194 days from the start of use of FreeStyle Libre, between September 2014 and July 2018. To minimise selection bias, all patients that had used FreeStyle Libre for at least 3 months from each study site were included in the analysis. After at least 3 months of using FreeStyle Libre, HbA1c (primary outcome) was significantly reduced by 0.9±0.8% (mean±SD); p Disclosure P. Fasching: None. H.
