Updated on 30 April 2021


The purpose of this study is to look at feasibility (the likelihood) of continued use of the FreeStyle Libre 2 Continuous glucose monitor (CGM) when started at the time of hospital discharge in patients with poorly controlled diabetes and to look at the effects of CGM use on blood glucose control and quality of life. Additional information will be collected to determine the barriers to continuing CGM use after discharge. The investigators will also collect information to see how well blood glucose has been controlled after discharge while utilizing the CGM.
