Introduction :
Improve glycemic control by means of intensive diabetes management decreases the risk of DM complications. Continuous glucose monitoring (CGM) generates continual data which can help patients & health care professionals to make informed and timely treatment decisions.
Objectives :
To explore the utility of the continuous glucose monitoring system as an outpatient tool in diabetic patients with suboptimal DM control.
Methodology :
One hundred diabetic patients were recruited to use 1 of 3 types of CGM device (HA annual plan funding) under patient selection criteria from July 2020 to Apr 2021 in TWEH DM clinic. CGM was performed for 7 to 14 days. After downloading and analyzing the data, results were discussed with the patients. They were advised on about lifestyle modification or regimen changes. The changes in HbA1c levels & hypoglycemia episodes from baseline to 3-6 months were analyzed.
Result & Outcome :
Data were available from 96 patients (14 with Type 1 DM, 82 with type 2 DM, 56% male, mean age 60.4, mean duration of DM 19.8 years). The baseline HbA1c was 8.55% +/-1.46% pre-CGM and decreased to 8.23%+/-1.36% after 3-6 months (p=0.003). Number of patients with hypoglycemic episodes decreased significantly from 54 to 23. No adverse event occurred.
