The investigators propose to conduct a study of practices to describe the methods of managing glycemic control in hospitalized patients in critical care. This is a prospective multicenter observational study conducted in Intensive Medicine and Resuscitation departments in France and Belgium. The aim of this study is to carry out an inventory of the current practices of glycemia management as well as their modalities. Being one of the key points of the management, this work will have for main objective to raise the importance of the glycemic variabilities according to the methods of insulin therapies used.
