Abstrakt
INTRODUCTION: Increased access to modern technologies is not always accompanied by a decrease in HbA1c. The aim of this study was to identify changes in the proportion of CGM users since 2017, when general reimbursement for CGM became effective in Czechia, and to test whether HbA1c is associated with the percentage of time spent on CGM.
METHODS: All T1D children in the Czech national ČENDA registry (3197 children) were categorized according to their time spent on CGM and associations with age, sex, center size and HbA1c were tested with calendar year as a stratification factor. RESULTS: The proportion of children with any CGM use increased from 37.9% in 2017 to 50.3% in 2018 and 74.8% in 2019.
Of the CGM users, 16%, 28%, and 41% of the children spent > 70% of their time on CGM over the 3 years of the study period, with an overrepresentation of children in the 100 patients) (p 70% category. Reimbursement for CGM likely contributes to the improvement of T1D control at the population level.
