This study is a German, prospective, multicenter, controlled, cluster-randomized, interventional comparative study evaluating the efficacy and benefits of integrated PDM care by measuring HbA1c levels in patients with Type 2 Diabetes. Patients will be randomized into two groups to use Accu-Chek Smartpix software and Accu-Chek Smartpix device.

Outcome of both studies (RD001732 and RD001231) will be integrated and additionally reported as PDM-ProValue study program (Integrated Personalized Diabetes Management) due to the high similarity in study characteristics, design and study results.
