A randomized controlled trial of a nurse short-message service by cellular phone for people with diabetes

Nurse's education using telemedicine results in a decrease in blood glucose levels in patients with type 2 diabetes. To investigate the effectiveness of an educational intervention that used both the cellular phone and the Internet to provide a short-messaging service (SMS) relating to plasma glucose levels. Twenty-five patients were randomly assigned to an intervention group and 26 to a control group. The intervention was applied for 12 weeks. The goal of the intervention was to keep blood glucose concentrations close to the normal range. Patients in the intervention group were asked to access a website by using a cellular phone or to wiring the Internet and input their blood glucose levels every day. Participants were sent the optimal recommendations by both cellular phone and the Internet weekly. Patients in the intervention group had a mean decrease in glycosylated haemoglobin (HbA 1c) levels of 1.15% and those in the control group had a mean increase of HbA 1c levels of 0.07% ( p=0.005). There was a significant mean change in the 2 hrs post-meal glucose (2HPMG) level for the intervention group ( p
