Use of CGM for Diabetes Management Following a Hospitalization.

Patients with diabetes hospitalized for heart failure or acute myocardial infarction will have a continuous glucose monitor (CGM) placed on the day of discharge which will be downloaded at their outpatient follow up clinic visit 6-14 days later. At the follow-up visit medications may be modified based on downloaded glucose data. This study is designed to determine the frequency that patients with diabetes hospitalized for heart failure or acute myocardial infarction have significant hypoglycemia or hyperglycemia requiring medication adjustment in the 1-2 weeks following hospital discharge. The outcome will be a binary- yes, diabetes medications were adjusted or no, diabetes medications were not adjusted. As a secondary outcome 30-day hospital readmission and mortality will be compared to historical hospital data collected by the inpatient cardiovascular service as part of their quality improvement monitoring. Researchers do not expect to see a significant difference in 30-day readmission or mortality as this study will be under-powered. In addition, our inclusion criteria will specifically target the patients at highest risk for bad diabetes outcomes, thus researchers may see worse outcomes compared to historical controls, but this assessment will help us design future randomized studies.
