Study Finds Dramatic Drop in Ketoacidosis Rate after FreeStyle Libre System Initiation in People with Type 1 and Type 2 Diabetes

CHICAGO, June 13, 2020 /PRNewswire/ -- People using Abbott’s FreeStyle Libre, a sensor-based glucose monitoring system, experienced a considerable decrease in ketoacidosis-related hospitalizations—52% for type 1 diabetes and 47% for type 2 diabetes—according to the study titled “Dramatic Drop in Ketoacidosis Rate after FreeStyle Libre System Initiation in Type 1 and Type 2 Diabetes in France, Especially in People with Low Self-Monitoring of Blood Glucose (SMBG): A Nationwide Study,” presented today at the American Diabetes Association’s^® (ADA’s) 80^th Virtual Scientific Sessions.

The trial, known as the “RELIEF” study, is the largest study to date on the impact of the FreeStyle Libre system on rates of hospitalization for diabetic ketoacidosis (DKA), a life-threatening condition that is generally preventable through close glucose monitoring.

Researchers retrospectively analyzed DKA rates using ICD-10 codes (E10.1, E11.1), on the French national claims database, among 33,203 people with type 1 diabetes (T1D) and 40,955 people with type 2 diabetes (T2D) who used the FreeStyle Libre system between August 1, 2017 and December 31, 2017. DKA rates were recorded in the year prior to the first FreeStyle Libre sensor claim and in the year after.

The data analysis revealed:

• Overall, yearly DKA rates were reduced after FreeStyle Libre system initiation by 52% for patients with T1D and 47% for patients with T2D.
• Results were most marked in the sub-population of patients who did not use self-monitoring blood glucose testing (SMBG) in the year prior to FreeStyle Libre system use (60% reduction for patients with T1D and 51% reduction for patients with T2D).
• People with the most regular use of SMBG testing (more than five blood glucose test strips reimbursed per day) also experienced marked reductions in hospitalizations (59% for T1D and 52% for T2D).
• A reduction in hospitalization rates for DKA was observed among patients treated with multiple daily injections, as well as patients who used continuous insulin infusion.

“This was a dramatic reduction in ketoacidosis-related hospitalization rates among patients with both type 1 and type 2 diabetes—especially among people who previously had very low self-monitoring of blood glucose—and supports the use of intermittently scanned continuous glucose monitoring systems like the FreeStyle Libre for individuals who are at risk for diabetes related complications such as diabetic ketoacidosis,” said lead study author Ronan Roussel, MD, PhD, chief of the endocrinology, diabetes, and nutrition department at Hôpital Bichat, Fédération de Diabétologie, AP-HP, Paris, France. “It is plausible that the use of the FreeStyle Libre system allowed people to detect and limit persistent hyperglycemia, and subsequently prevent ketoacidosis. Although preventing ketoacidosis has traditionally relied on intensive self-monitoring of blood glucose, there is growing literature that shows this has not helped reduce the overall incidence of diabetic ketoacidosis. The positive results of this study demonstrate that intermittently scanned continuous glucose monitoring may have significant implications for patient-centered clinical care and, given the increased burden of ketoacidosis on healthcare utilization and expenditure, it may have a positive impact on long-term economic health outcomes.”

About the ADA’s Scientific Sessions
The ADA’s 80th Scientific Sessions, the world’s largest scientific meeting focused on diabetes research, prevention and care, is being held virtually June 12-16, 2020. Leading physicians, scientists and health care professionals from around the world will unveil cutting-edge research, treatment recommendations and advances toward a cure for diabetes. Though the conference will be remote this year, attendees will receive exclusive access to nearly 2,000 original research presentations and take part in provocative and engaging exchanges with leading diabetes experts. Learn more and register at scientificsessions.diabetes.org and join the Scientific Sessions conversation on social media using #ADA2020 and #ADAGoesVirtual.

About the American Diabetes Association
Every day more than 4,000 people are newly diagnosed with diabetes in America. More than 122 million Americans have diabetes or prediabetes and are striving to manage their lives while living with the disease. The American Diabetes Association (ADA) is the nation’s leading voluntary health organization fighting to bend the curve on the diabetes epidemic and help people living with diabetes thrive. For nearly 80 years the ADA has been driving discovery and research to treat, manage and prevent diabetes, while working relentlessly for a cure. We help people with diabetes thrive by fighting for their rights and developing programs, advocacy and education designed to improve their quality of life. Diabetes has brought us together. What we do next will make us Connected for Life. To learn more or to get involved, visit us at diabetes.org or call 1-800-DIABETES (1-800-342-2383).
