Yes, several studies have been conducted to study the ability of telemedicine to help patients achieve better diabetes types self-management. A study published in the Diabetes Journal was conducted in South Carolina and followed patients with diabetes; some were followed through a telemedicine program, while others were followed in the usual way, through on-site physician follow-ups. Those followed through on-site follow-ups saw only a 2% reduction in their Haemoglobin A1c levels, while the average A1c of those in the telemedicine decreased by almost 12 %. Subjects in the telemedicine group also experienced greater weight loss and improvements in their LDL (“bad”) cholesterol levels.
