Hemoglobin A1c as a screen for previously undiagnosed prediabetes and diabetes in an acute-care setting.

ABSTRACT:

Objective

Hemoglobin A(1c) (HbA(1c)) is recommended for identifying diabetes and prediabetes. Because HbA(1c) does not fluctuate with recent eating or acute illness, it can be measured in a variety of clinical settings. Although outpatient studies identified HbA(1c)-screening cutoff values for diabetes and prediabetes, HbA(1c)-screening thresholds have not been determined for acute-care settings. Using follow-up fasting blood glucose (FBG) and the 2-h oral glucose tolerance test (OGTT) as the criterion gold standard, we determined optimal HbA(1c)-screening cutoffs for undiagnosed dysglycemia in the emergency department setting.

Research design and methods

This was a prospective observational study of adults aged ≥18 years with no known history of hyperglycemia presenting to
