REAL WORLD STUDY OF FREESTYLE LIBRE SYSTEM AMONG ADULTS WITH TYPE 1 AND TYPE 2 DIABETES WITHIN THE SWEDISH NATIONAL DIABETES REGISTER
Background and Aims
The National Diabetes Register (NDR) launched in 1996 in Sweden includes primary and secondary care data and captures 94% of adult patients with diabetes. NDR initiated documentation of FreeStyle Libre usage in June 2016 and offers a unique opportunity to monitor the quality of diabetes care.
A cohort study using data from nationwide register from January 2014 to the 25th of June 2019 was initiated with the objective to better understand the data collected within the register and determine the effectiveness of the FreeStyle Libre system on HbA1c. The study population included all patients with diabetes (≥ 18 years old) using FreeStyle Libre recorded within the NDR. There were no exclusion criteria. Index date was the 1st record of FreeStyle Libre use. Methodology was a before/after comparison; prior period was closest HbA1c measurement within 6 months before index date and after period was HbA1c closest to 6 months after index date within Day 91 – Day 272.
During the study period, 40 793 T1 or T2 patients had at least one registration of FreeStyle Libre usage. HbA1c measurements were available within the defined prior and after period for a subset of the total patient study population who were incident FreeStyle Libre users (June 2016 to June 2019). HbA1c was significantly reduced in T1 and T2 users.
This large real-world study on a well-established diabetes register in Sweden concluded that people with T1DM and T2DM using FreeStyle Libre for between 3 to 9 months significantly reduced HbA1c.
