Use of a Data Management System to Provide Glycemic Control Instructions to Diabetic Patients Based on Patient Self-Measured Blood Glucose

To make the treatment for diabetes more effective, we assessed the effects of a data management system for glycemic control. This system enables physicians at distant medical institutions to obtain the fluctuations in blood glucose (BG) measured daily by patients themselves at home and then to give instruction for treatment based on the BG. Use of the system for 2 months resulted in decreases in the hemoglobin A1c (HbA1c) level (from 6.8% ± 0.9% to 6.6% ± 0.8% [M ± SD], p < .05) and the incidences of preprandial hypoglycemia and postprandial hyperglycemia. These effects can be concluded to have resulted from the fact that physicians become able to give patients appropriate instructions quickly. Also, these effects are considered to have resulted from patient awareness of the importance of self-management of BG.
