Mobile phone text messaging in the management of diabetes

We conducted a trial of mobile phone text messaging (short message service; SMS) for diabetes management. In an eight-month period, 23 diabetic patients used the service. Patients used SMS to transmit data such as blood glucose levels and body weight to a server. The server automatically answered with an SMS acknowledgement message. A monthly calculated glycosylated haemoglobin result was also automatically sent to the patient by SMS. During the trial the patients sent an average of 33 messages per month. Although users showed good acceptance of the SMS diabetes system, they expressed various concerns, such as the inability to enter data from previous days. Nonetheless, the trial results suggest that SMS may provide a simple, fast and efficient adjunct to the management of diabetes. It was particularly useful for elderly persons and teenagers, age groups that are known to have difficulty in controlling their diabetes.
