Study of Stress Hyperglycemia as an Indicator of Diabetes Mellitus

Stress Hyperglycemia as an Indicator for Future Diabetes Mellitus: A Prospective Cohort Study

We hypothesize that stress hyperglycemia is an indicator that a patient will develop type 2 diabetes mellitus in the future. Subjects who are not diabetic are enrolled and blood glucose readings reviewed during their intensive care unit stay. All subjects are consented and have a HbA1C level drawn to determine if they have diabetes mellitus or not. They are then followed up in 1 year and the HbA1C repeated to determine if they have developed diabetes mellitus over the course.

Inclusion Criteria:

• All patients admitted to the intensive care unit at the Yale New Haven Hospital St. Raphael Campus and Norwalk Hospital

Exclusion Criteria:

• Patients with prior history of diabetes mellitus
• Elevated admission HbA1c (≥6.5%)
• Age >80 years
• Metastatic disease with expected life expectancy of less than 12 months
• Pregnancy or a woman who plans to become pregnant
