Health Indicator Report of Diabetes Hemoglobin A1C Tests

Proper diabetes management requires regular monitoring of blood sugar levels. Glucometers provide immediate feedback on blood sugar levels. An A1C test, however, tells a person what his or her average blood sugar level has been over the past two or three months and is a more reliable indicator of blood sugar control. An A1C level indicates the amount of sugar that is attached to red blood cells (hemoglobin cells). Red blood cells are replaced every two or three months and sugar stays attached to the cells until they die. When levels of blood sugar are high, more sugar is available to attach to red blood cells. For most people with diabetes, the target A1C level is less than 7 percent. Higher levels suggest that a change in therapy may be needed. Therefore, obtaining regular A1C tests plays an important role in diabetes management. The American Diabetes Association [http://care.diabetesjournals.org/cgi/content/full/27/suppl_1/s15#T7 recommends] that people with diabetes have an A1C test at least two times a year. However, the test should be conducted more often for individuals who are not meeting target blood sugar goals, or who have had a recent change in therapy.
The figure above shows age-adjusted rates of adults with diabetes who had 2 or more A1C tests in the past year by local health district. Weber-Morgan Local Health District has the highest rate of A1C testing at 87.8%. Utah County Local Health District has the lowest rate at 45.4%.

Notes

Beginning in 2011, BRFSS data include both landline and cell phone respondent data along with a new weighting methodology called iterative proportional fitting, or raking. This methodology utilizes additional demographic information (such as education, race, and marital status) in the weighting procedure. Both of these methodology changes were implemented to account for an increased number of U.S. households without landline phones and an under-representation of certain demographic groups that were not well-represented in the sample. This graph is based on the new methodology. More details about these changes can be found at the following [https://ibis.health.utah.gov/pdf/opha/resource/brfss/RakingImpact2011.pdf link].   Prior to 2015 San Juan County was part of the Southeast Local Health District. In 2015 the San Juan County Local Health District was formed.

Definition

Percentage of adults aged 18 or older with diagnosed diabetes who self-report they had at least two A1C tests during the prior 12 months.

Numerator

Number of adults 18 or older with diagnosed diabetes who had at least two A1C tests in the past 12 months.

Denominator

Total number of surveyed adults 18 or older who were ever told by a health care professional that they had diabetes (excludes women with a history of gestational diabetes). Responses of "Don't know" and "Refused" were excluded from the analysis.

Healthy People Objective D-11:

Increase the proportion of adults with diabetes who have a glycosylated hemoglobin measurement at least twice a year
U.S. Target: 71.1 percent

Other Objectives

The American Diabetes Association recommends a target A1C level of less than 7%. This level corresponds to an average plasma blood glucose level of 170 mg/dL over the past 60-90 days. The Healthcare Effectiveness Data and Information Set (HEDIS) uses indicators to measure performance by health plans in the U.S. The HEDIS A1C indicator measures the number of insured adults who have at least one A1C test a year. Please [https://ibis.health.utah.gov/ibisph-view/indicator/view/HEDISHbA1c.html see] the HEDIS A1C indicator that is included in the IBIS-PH list.

How Are We Doing?

The percentage of people with diabetes who had at least two A1C tests a year is approximately 70% in Utah and in the U.S.

How Do We Compare With the U.S.?

The 2019 age-adjusted rate for Utah is higher than that for the U.S., 70.2% vs. 69.2%, respectively. However, the U.S. data only includes 24 states.

What Is Being Done?

A public service announcement from the Utah Department of Health regarding A1C testing, [https://www.youtube.com/watch?v=vWJkgo8XYNc "Do you wish you could reverse time?"] is available for view in English and Spanish. Diabetes educators play a prominent role in providing information about nutrition, exercise, and blood glucose monitoring. Diabetes education for all people with diabetes is encouraged. The Utah Healthy Living through Environment, Policy, and Improved Clinical Care ([http://choosehealth.utah.gov/ EPICC]) Program promotes diabetes education throughout the state. EPICC also provides monthly Telehealth broadcasts to update health care professionals on the latest diabetes treatments and research. EPICC meets with representatives from local health insurance plans to discuss opportunities for quality improvement in treatment for their clients with diabetes.

Evidence-based Practices

Diabetes Self-Management Education and Support ([https://www.cdc.gov/diabetes/managing/education.html DSMES]) has been shown to improve blood glucose control in people with diabetes. Education programs may be certified by the American Diabetes Association or the Association of Diabetes Educators. Here is a [https://livingwell.utah.gov/program.php?grp=diab list] of DSMES programs available in Utah.
