Abstract
OBJECTIVES: This study aimed to evaluate real-world glycaemic outcomes associated with flash glucose monitoring (FGM) use in patients with diabetes at Sultan Qaboos University Hospital, Muscat, Oman. METHODS: This retrospective cross-sectional study was conducted among diabetic patients using flash glucose monitoring between January 2022 and August 2023. Patients were grouped by scanning frequency, time-in-range (TIR) and estimated A1c (eA1c). Associations between scanning frequency and glycaemic metrics were analysed. RESULTS: A total of 436 patients were included in this study. Patients with higher scanning frequency (≥12 scans/day, median = 17) achieved greater TIR (52.4% versus 34.8%), lower time-above-range (41.8% versus 57.0%), lower eA1c (7.7% versus 9.0%) and lower glucose standard deviation (70.22 mg/dL versus 82.21 mg/dL) compared with those with the lowest scanning frequency (≤3 scans/day). No significant association was found between scanning frequency and time-below-range or glucose coefficient of variation. CONCLUSION: Frequent FGM scanning was associated with improved glycaemic control in Omani diabetes patients, supporting its role in real-world diabetes management.
