Background: Continuous glucose monitoring (CGM) might have beneficial effects on glycemic control and body mass index (BMI) in adults with type 1 (T1D) or type 2 diabetes (T2D). Methods: The diabetes prospective follow-up registry was used to identify individuals with T1D or T2D ≥18 years starting CGM management in 2015 or later and follow-up information available. Hemoglobin A1c (HbA1c), BMI, and event rates of severe hypoglycemia in the year before CGM start were compared with two follow-up periods: (1) CGM use for 3-6 months and (2) CGM use for >6 months. Repeated measurements linear and negative binomial regressions were used (adjustment for sex, age at diabetes onset, and baseline parameters) and stratified by diabetes type. Results: Mean follow-up time was 1.8 years in T1D ( n  = 2994) and 1.9 years in T2D ( n  = 1440). In T1D, adjusted mean HbA1c decreased significantly from 7.65% (95% confidence interval: 7.62-7.68) at baseline to 7.54% (7.51-7.57) during follow-up. BMI increased slightly (baseline: 25.4 kg/m 2 [25.3-25.5], follow-up >6 months: 25.8 kg/m 2 [25.7-25.9]), whereas event rates of severe hypoglycemia were significantly lower after >6 months with CGM (9.0 events/100 patient-years [PY; 8.0-10.1]) compared with baseline (11.3 events/100 PY [10.4-12.2]) in adults with T1D. In T2D, HbA1c decreased from 7.21% (7.17%-7.25%) to 7.00% (6.95%-7.04%) and BMI did not change after CGM initiation. Conclusion: Our results provide real-world evidence on CGM management in adult individuals with T1D or T2D. We suggest strengthening patients' and physicians' readiness toward diabetes technology in T2D and more openness of health insurance to cover cost based on proven benefits.

Aims: To analyse time trends of antihyperglycaemic therapy and glycaemic control in adult subjects with type 1, or type 2 diabetes between 2002 and 2014 in Germany/Austria.Methods: 184,864 adults with diabetes (35,144 type 1 diabetes (T1D), 149,720 type 2 diabetes (T2D)) from the DPV-database documented between 2002 and 2014 were included. Regression models were applied for antihyperglycaemic therapy in T2D (non-pharmacological, OADs only, insulin±OADs), insulin therapy in T1D (CT, ICT, CSII) and T2D (BOT, SIT, CT, ICT, CSII), for the use of insulin analogues, and for glycaemic control (HbA1C, severe hypoglycaemia), adjusting for confounders sex, age, and diabetes duration.Results: In T1D, CT (2002:19.7%; 2014:16.0%) and ICT (2002:66.8%; 2014:52.4%) decreased, while CSII increased from 13.5% to 31.5%. In T2D, non-pharmacological treatment became less frequent (2002:36.0%, 2014:21.8%), the use of OADs (2002:19.3%, 2014:28.9%) and insulin±OADs (2002:44.6%, 2014:49.4%) increased. BOT increased from 7.9% to 18.9%, SIT decreased from 12.0% to 8.3%. ICT slightly increased (2002:44.0%, 2014:45.3%), CT decreased (2002:35.8%, 2014:27.2%). Insulin analogues were used more frequently in T1D (rapid-acting:2002:46.8%, 2014:84.8%; long-acting:2002:26.0%, 2014:54.8%) and in T2D (rapid-acting:2002:26.0%, 2014:43.5%; long-acting:2002:13.7%, 2014:53.6%). Until 2011, HbA1C increased in T1D and T2D, but then decreased again. High variability in the rate of hypoglycaemia was observed.Conclusions: This observational study indicates an increased use of insulin pumps in T1D. In T2D, non-pharmacological therapy decreased, and insulin therapy, particular as BOT, rose. An increase in the use of rapid- and long-acting insulin analogues was present in both patient-groups. Time trend was less clear in glycaemic control. [ABSTRACT FROM AUTHOR]
