Abstract
The purpose of this study was to investigate the effect of a nurse short message service by cellular phone and the Internet on glycosylated hemoglobin (HbA1c) levels and adherence to diabetes control recommendations. The patients with diabetes were asked to input their blood glucose levels every day by cellular phone or the Internet. Optimal recommendations were sent weekly to each patient by short message service. After 12 weeks, the patients had a mean decrease of 1.1% in HbA1c level and an increase in diabetic medication taking, 30 minutes of physical exercise, and foot care adherence.
