Introduction: Telemedicine is a follow-up system that can improve the quality of management and cost-effectiveness of rapidly increasing diabetes patients. Methods: Two hundred adult patients with diabetes were enrolled in this prospective, randomized study. Consecutive patients were divided equally into two groups. Both groups received routine care visits quarterly. TeleDiab group also sent self-monitoring of blood glucose data and received short message service over the transmission system for 12 months. After the study was completed, all patients continued their routine care visits, and their data were evaluated for another 12 months. Six years after the initial study, patients were contacted by phone during the Covid-19 lockdown, and their status was assessed. Results: At the end of the study, glycemic control, kidney function, and lipid parameters of the TeleDiab group were statistically significantly better than the Usual Care group. There was no significant change in the weights of the patients. It was observed that this state of wellbeing continued both at the end of the second year and during the Covid-19 lockdown. Individuals with type 2 diabetes were found to benefit more from telemedicine. Discussion: It has been beneficial to guide patients with applications such as TeleDiab in diseases such as diabetes that require lifelong follow-up. On the other hand, the importance of telemedicine programs in the management of chronic diseases in the current pandemic conditions has come to the fore even more. Telemedicine is an effective motivational tool to ensure optimal control not only of glycemic but also of kidney and lipid parameters.
