title: A randomized controlled trial of a nurse short-message service by cellular phone for people with diabetes.
abstract: BACKGROUND
  Nurse's education using telemedicine results in a decrease in blood glucose levels in patients with type 2 diabetes.
  
  
  OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  Patients in the intervention group had a mean decrease in glycosylated haemoglobin (HbA(1)c) levels of 1.15% and those in the control group had a mean increase of HbA(1)c levels of 0.07% (p=0.005). There was a significant mean change in the 2hrs post-meal glucose (2HPMG) level for the intervention group (p<0.05), with a mean change of -4.7mmol/l. The mean change in the control group was not significant.
  
  
  CONCLUSIONS
  This educational intervention using the Internet and an SMS by cellular phone improved levels of HbA(1)c and 2HPMG.
