  Purpose

Previously we demonstrated the beneficial effects of an Internet-based glucose-monitoring system (IBGMS) in people with type 2 diabetes mellitus. The “Diabetes Phone”, a cellular phone with a glucometer integrated in the battery pack, was launched in Korea in 2003. Here we test the short-term effectiveness of the diabetes phone for glucose control and compare it with that of IBGMS.

Detailed Description:

Various strategies using electronic technologies or educational programs have been proposed to improve the quality and efficiency of care for people with diabetes. In the previous study, we introduced a new bidirectional communication tool for diabetes management termed the Internet-Based Glucose Monitoring System (IBGMS), and demonstrated its short-term and long-term effects on glycemic control in type 2 diabetic patients. Other researchers have also showed the effectiveness of telecommunication between health-care providers and patients for maintaining appropriate blood glucose control. These systems allow patients to send data to doctors, identify specific problems and receive recommendations from health-care providers more frequently and with fewer time and place limitations than at traditional face-to-face outpatient clinics. With the IBGMS, physicians can monitor patients’ self-monitored blood glucose data at regular intervals, and patients can communicate with their physicians whenever they have any questions. Although bidirectional interactive communications between physicians and patients can be achieved with the IBGMS, there remain time and place limitations. Patients must connect to the Internet using their personal computer to input their data or questions on the IBGMS, while physicians only visit the website at regular intervals unless they have received questions from patients.

To improve the efficiency of communication, we linked the IBGMS to the short message service (SMS) delivered by cellular phone. The patients sent their data to doctors through the IBGMS and then received the doctors’ recommendations about adjustment of drug dosage and other related data on the cellular phone. This system improved the efficiency of communication and patients’ satisfaction also slightly increased. However, patients were still limited by place and time when sending questions and blood glucose-monitoring data.

Recently, cellular phones have been developed that can measure blood glucose level and transmit data directly to a web server (Diabetes Phone). The combination of a glucometer with the cellular phone function makes it easier for patients to report their self-monitored blood glucose (SMBG) levels and receive feedback from their doctors. However, it was not known how effective this cellular phone glucose-monitoring system would be for control of blood glucose levels, compared to the IBGMS tested previously. We investigated the effectiveness of the diabetes phone for blood glucose control and compared it with that of the IBGMS.
