OBJECTIVE The RELIEF study assessed rates of hospitalization for acute diabetes complications in France before and after initiation of the FreeStyle Libre system. RESEARCH DESIGN AND METHODS A total of 74,011 patients with type 1 diabetes or type 2 diabetes who initiated the FreeStyle Libre system were identified from the French national claims database with use of ICD-10 codes, from hospitalizations with diabetes as a contributing diagnosis, or the prescription of insulin. Patients were subclassified based on self-monitoring of blood glucose (SMBG) strip acquisition prior to starting FreeStyle Libre. Hospitalizations for diabetic ketoacidosis (DKA), severe hypoglycemia, diabetes-related coma, and hyperglycemia were recorded for the 12 months before and after initiation. RESULTS Hospitalizations for acute diabetes complications fell in type 1 diabetes (−49.0%) and in type 2 diabetes (−39.4%) following FreeStyle Libre initiation. DKA fell in type 1 diabetes (−56.2%) and in type 2 diabetes (−52.1%), as did diabetes-related comas in type 1 diabetes (−39.6%) and in type 2 diabetes (−31.9%). Hospitalizations for hypoglycemia and hyperglycemia decreased in type 2 diabetes (−10.8% and −26.5%, respectively). Before initiation, hospitalizations were most marked for people noncompliant with SMBG and for those with highest acquisition of SMBG, which fell by 54.0% and 51.2%, respectively, following FreeStyle Libre initiation. Persistence with FreeStyle Libre at 12 months was at 98.1%. CONCLUSIONS This large retrospective study on hospitalizations for acute diabetes complications shows that a significantly lower incidence of admissions for DKA and for diabetes-related coma is associated with use of flash glucose monitoring. This study has significant implications for patient-centered diabetes care and potentially for long-term health economic outcomes.

IntroductionThe objective of this study was to document the initiation of insulin therapy in patients with type 2 diabetes mellitus (T2DM) and its maintenance as a function of time after initiation in a French nationwide representative cohort.MethodsA retrospective cohort study was conducted on a random sample of ~600,000 beneficiaries registered in the French national health insurance database. Newly insulin treated T2DM patients were selected. Persistence was defined as remaining on insulin without discontinuation (defined over a 6 or a 12-month period).ResultsAmong 1909 initiations identified in 2012/2013 (basal scheme: 61.8%, basal/rapid: 15%, other schemes: 23.2%) the average age (standard deviation) at initiation was, respectively, 67.5 (14.2), 61.8 (18.1) and 63.2 (18.4) years. Insulin was initiated by general practitioners in 39.3% and prescribed without other antidiabetic drugs in 32.0%. Persistence was studied in 1969 patients initiating insulin in 2011/2012. Among survivors, nearly 25% stopped insulin during the first year (18.4% for basal scheme). Patients discontinuing insulin were younger [64.7 years (18.5) vs 67.3 years (14.3) p = 0.0003] and less often male (45.8% vs 55.7%, p < 0.0001). A proportion of 20.2% did not receive any antidiabetic drug over 12 months after discontinuation. These high percentages were only partly explained by transient intensive insulin regimens in acutely ill patients identifiable in the database.ConclusionWe observed a high rate of early discontinuation of insulin in T2DM patients (but lower with basal insulin scheme). Further real world studies are warranted to identify factors associated with this poor persistence.FundingThis study was supported by Sanofi-France.

Most varicella-zoster virus infections occur during early childhood. Seroprevalence rates reach approximately 50% by 4 years of age and approximately 90% by 8 years. Therefore, the best strategy to reduce the prevalence of wild-type varicella-zoster virus in the French population would be to immunize children 12-18 months of age, as is currently performed in the United States.

Although this series contains mostly gastric bandings, which were less likely to affect comorbidities, the workup for preparing BS was probably an opportunity to benefit from a general clinical assessment which has generated extra short-term medical consumption and expenses began decreasing without allowing return on investment.
