Controlled Type 2 Diabetes Patients Excessively Tested

Medical Team Looking at Xray Medical Team

A study from the Veterans Affairs Administration found that among patients who are newly diagnosed with diabetes, 38 percent were tested at least three times and 4.2 percent were tested at least five times during their first year. As to patients with stable or controlled disease, testing more than the recommended once or twice annually may not receive a benefit from the testing, which may also contribute to healthcare cost, resources, and treatment burden. Patients testing five or more times a year is redundant due to A1c being a measure of average blood glucose over three months. Over testing may cause overtreatment, which puts the patient at harm for hypoglycemia, increased healthcare cost, and potential adverse effects.
