Prevalence of undiagnosed dysglycemia in an emergency department observation unit

BACKGROUND: The proposed 2015 US Preventive Services Task Force guidelines recommend diabetes screening for individuals \u3e/=45 years or demonstrating other risk factors for dysglycemia. Still, many patients with dysglycemia remain undiagnosed, and opportunities for early intervention are lost. METHODS: To test novel approaches for diagnosis using the haemoglobin A1c (HbA1c ) test, we screened adult patients who were admitted to an observation unit from the emergency department with no known history of pre-diabetes or diabetes. RESULTS: Of 256 subjects, 9% were newly diagnosed with diabetes and 52% were newly diagnosed with pre-diabetes. Of those aged 18-29 years, 33% were newly diagnosed with dysglycemia, while 55% of those aged 30-44 years and 70% of those aged \u3e/=45 years were newly diagnosed with dysglycemia. CONCLUSIONS: Our results suggest that regardless of age, a large proportion of patients in the emergency department observation unit have undiagnosed dysglycemia, an important finding given the large number of observation admissions.
