Recently we designed an Internet-based diabetic patient management using short message service (SMS) that was automatically produced by a knowledge matrix. Moreover, we reported this unique system has shown the great efficacy in glucose control. In this study, we designed the system in patients treated with long acting insulin to produce an automatic adjustment of insulin dose based on real time glucose level data and to provide to the patients the needed insulin dose by using a SMS and apply to the clinical practice with diabetic patients.
