Results: Various strategies using electronic technologies have been proposed to improve standards of care for diabetic patients, but their long-term effectiveness is still questioned. We investigated the effectiveness of an internet-based glucose monitoring system for controlling changes in HbA1c levels over 30 months.We conducted a randomized clinical trial involving 71 diabetic patients at the outpatient clinic at Kangnam St. Mary's Hospital. The intervention group was treated using the monitoring system for 30 months, while the control group received conventional outpatient management. Measurements HbA1c and other laboratory tests were performed at the beginning and at the end of the study. We performed follow-up tests for HbA1c levels at three-month intervals.The intervention group, with a basal HbA1c ≥ 7.0%, showed markedly lower HbA1c levels than the controls during the first three months and maintained stable levels below 7.0% during the whole period. The control group, with a basal HbA1c < 7.0% showed a characteristic bimodal distribution. Although there were no significant overall differences in basal HbA1c levels, the mean HbA1c of intervention group was significantly lower that that of control group in both the fractions of HbA1c ≥ 7.0% and < 7.0%. The AHFA index (monthly cumulative percentage HbA1c fluctuation from the average) of the intervention group was also significantly lower than controls. Thus, the intervention group showed better glucose control pattern than the control group.We demonstrated the long-term effectiveness of this internet-based glucose monitoring system, and believe that this system deserves wider application for controlling diabetes.
