Real-World Flash Glucose Monitoring in a Developing Country

Previous studies showed results of flash glucose monitoring (FreeStyle LibreTM) in European countries. This study evaluated real-world impact of device use and glucose metrics using a cross-sectional observational design in a developing country - Brazil. A server collected de-identified data from readers, and completed sensors (>120 hours of operation) were analysed. Comparison of 1,569,588 sensors (237,747 readers) worldwide were made with 57,713 sensors (8,979 readers) from Brazil. Readers were divided into 10 rank-ordered groups by daily scan rate. Users worldwide performed a mean (±SD) of 13.2±8.9 daily glucose scans and a rate of 13.5±9.1/day in Brazil (p=0.002). Time in range (70-180 mg/dL) increased from 13.5 to 16.2 h/day (20% increase, p
