2 EmergencyKT: Use of HbA1c in the Emergency Department What is a Hemoglobin A1c (HbA1c)? HbA1c represents a patient s average glucose level over the last 1-4 months. HbA1c measures the percentage of glycosylated hemoglobin in the blood and thus reflects the average glucose level over the life of a red blood cell (120 days) and the hemoglobin it contains. Because of the constant turning over of red blood cells, more recent glucose levels (ie. the last few weeks) have a greater effect on the HbA1c value than do those from 8 or 12 weeks ago. It is estimated that half of an HbA1c value is attributable to the previous month s glucose level, a further quarter to the month before that, and the other quarter to the two months before that. Since the HbA1c value is t influenced by daily fluctuations in blood glucose concentration, it should t be used to monitor day-to-day blood glucose concentrations and to adjust insulin treatment. Moreover, the HbA1c value may t reflect the day-to-day presence or absence of hyperglycemia and/or hypoglycemia. HbA1c level may be falsely increased in patients with: kidney failure, chronic excessive alcohol intake (Vit B12 and foliate deficiency), untreated iron deficient anemia, and hypertriglyceridemia HbA1c level may be falsely decreased in patients with: acute or chronic blood loss, sickle cell disease, hemolytic anemia/thalassemia. Why obtain an HbA1c in the Emergency Department? Without primary care and proper diabetes management it is extremely difficult for many diabetics to control their glucose levels. It is this lack of glycemic control that is ultimately responsible for the host of debilitating and potentially life threatening health complications associated with poorly controlled diabetes. Diabetic patients who present to the emergency department (and who lack adequate primary care or who are in need of improved diabetes management, education and/or follow up) should have their HbA1c level obtained. The result can then be used to assess the patient s current glycemic control and determine their urgency of needed follow up. The implementation of this tool could significantly reduce the number of unnecessary emergency department visits by decreasing the number of diabetic patients who use the emergency department as a means of obtaining primary care and by decreasing the incidence and severity of diabetic related complications that require emergency department treatment. This also has the potential to reduce costs by decreasing the number of emergency department visits and their related work ups.
