Awareness of HbA1c Levels Among Diabetes Patients Doubles Since 2006, According to Kantar Health Research

New results from the National Health and Wellness Survey show patients with type 2 diabetes who are aware of HbA1c levels are more likely to have diabetic complications.

Improved patient awareness of HbA1c levels may have societal benefits in terms of reduced costs as well as improved health outcomes for patients.

Awareness of HbA1c levels among patients with type 2 diabetes has nearly doubled in the past eight years, to 56 percent in 2013 from 27 percent in 2006, according to new findings from Kantar Health’s National Health and Wellness Survey (NHWS). The research will be presented today at the 19th Annual ISPOR (International Society for Pharmacoeconomics and Outcomes Research) Meeting in Montreal.

Patients who were aware of their HbA1c were more likely to be older (60.5 vs. 57.2 years), non-Hispanic white (71.4 percent vs. 61.1 percent), being treated with oral insulin or non-insulin injectable (87.8 percent vs. 76.1 percent), and more likely to have had diabetic complications compared with those who were unaware.

From an economic perspective, lack of awareness was associated with higher indirect costs, including work and activity impairment. Lack of awareness also was associated with more hospitalizations in the past six months though fewer physician visits, which may be related to the lack of awareness.

“For patients with type 2 diabetes, maintaining glycemic control can aid in the prevention of future microvascular and macrovascular complications. Proper awareness of HbA1C levels and targets is important to improve health outcomes,” said Kathy Annunziata, vice president, Research Services, Kantar Health. “Our research found that patients who are unaware of their HbA1c levels are less likely to be treated and also had fewer physician visits than patients who are aware, yet more hospitalizations, suggesting their disease is not being properly managed. Improved patient awareness of HbA1c levels may have societal benefits in terms of reduced costs as well as improved health outcomes for patients.”
