Abstract
BACKGROUND
Cellular phones are extremely prevalent in modern society and they enable appropriate feedback mechanisms through real time monitoring and short message services regarding blood glucose levels. We investigated whether cellular phone-based telemedicine support system could improve blood glucose control in type 2 diabetes patients who were in inadequate glycemic control regardless of insulin therapy. METHODS: A randomized, controlled clinical trial was conducted involving 74 type 2 diabetic patients with suboptimal glycemic control (HbA1c levels > 7%) regardless of insulin therapy. The intervention (cellular phone-based telemedicine) group managed their blood glucose using a cellular phone for 3 months, while the control (self monitoring of blood glucose) group managed their blood glucose with a standard glucometer for the same period. RESULTS: Three months later, HbA1c levels were decreased in both groups. However, the decrease in the control group from 8.37% to 8.20% was only 0.20% (P = 0.152) which was not significant. In contrast, the intervention group had a significant reduction of 0.61% from 8.77% to 8.16% (P < 0.001). Moreover, among patients with a baseline > or = 8%, the patients in the intervention group showed a significant reduction of 0.81% from 9.16% to 8.34% (P < 0.001). CONCLUSION: HbA1c levels were significantly decreased in the cellular phone-based telemedicine group compared with the control group after 3 months. This study suggests that cellular phone-based telemedicine is helpful for better glucose control in type 2 diabetes patients who previously were unable to control glucose levels adequately with insulin therapy.
