ADA recommendations increase blood pressure target to below 140 mm Hg systolic in diabetic patients

ACP Hospitalist

A higher maximum systolic blood pressure target for diabetics is one of the most significant changes in the American Diabetes Association's 2013 Standards of Medical Care.′

The standards, which are revised annually, are based on the most current scientific evidence and provide guidance on treating children and adults with all types of diabetes. They were published online Dec. 20, 2012, and in a special supplement to the January 2013 Diabetes Care.

Several changes were made to the recommendations for 2013, the most significant being an increase in the systolic blood pressure goal for many people with diabetes from less than 130 mm Hg to less than 140 mm Hg. The revision was based on several new meta-analyses showing little additional benefit from lower targets, according to a press release. However, lower targets may still be appropriate for some patients, for example those who are younger or have a higher risk of stroke, the recommendations noted.

Another recommendation change affects hospitalized patients who have not been previously diagnosed with diabetes. If such patients have risk factors for diabetes and exhibit hyperglycemia during hospitalization, physicians should consider obtaining a hemoglobin A1c test, the standards now say. The standards have also been updated to reflect new recommendations from the Centers for Disease Control and Prevention on hepatitis B vaccination. Diabetic patients age 19 to 59 should be vaccinated, and vaccination should be considered for those 60 and over.

Recommendations on self-monitoring of blood glucose for patients who take multiple doses of insulin per day have also changed. Previously, the recommendations called for self-monitoring three or more times a day. The 2013 standards specify that these patients should test their blood glucose prior to meals and snacks, occasionally after eating, at bedtime, before exercise, when hypoglycemia is suspected or has occurred and prior to critical tasks such as driving.

The new recommendations also contain changes regarding diabetes self-management education, screening and treatment of cardiovascular risk factors in prediabetes, and emphasizing statin therapy over specific low-density lipoprotein cholesterol goals.
