This review focuses on the burgeoning use of web-based systems allowing patient-initiated glucometer uploads to facilitate provider treatment intensification. Studies in type 1 diabetes tended to show equivalent HbA1c improvements in both intervention and control groups without statistically significant difference. In contrast, type 2 patients seemed to do better than controls with significant differences in HbA1c. Patients were the beneficiaries of web-based diabetes management both through savings in time and cost. Major obstacles to wider implementation are patient computer skills, adherence to the technology, architectural and technical design, and the need to reimburse providers for their care.
