Description

This measure is used to assess the percentage of members 18 to 64 years of age with diabetes (type 1 and type 2) whose most recent hemoglobin A1c (HbA1c) level is less than 7.0% (controlled).

This measure is a component of the Comprehensive Diabetes Care composite measure—one of 7 different rates—looking at how well an organization cares for the common and serious chronic disease of diabetes.

The denominator for all rates must be the same, with the exception of this HbA1c control (less than 7.0%) for a selected population measure.

Note from the National Quality Measures Clearinghouse (NQMC): For this measure, there are both Administrative and Hybrid Specifications. This NQMC measure summary is based on the Administrative Specification. Refer to the original measure documentation for details pertaining to the Hybrid Specification.

Rationale

Diabetes is one of the most costly and highly prevalent chronic diseases in the United States (U.S.). Approximately 26.5 million Americans have diabetes, and seven million of these cases are undiagnosed. Complications from the disease cost the country nearly $245 billion annually. In addition, diabetes is the seventh leading cause of death in the U.S. (American Diabetes Association, 2013). Many complications, such as amputation, blindness, and kidney failure, can be prevented if detected and addressed in the early stages.

Evidence for Rationale

Primary Health Components

Diabetes; hemoglobin A1c (HbA1c) testing

Denominator Description

Members 18 to 64 years of age as of December 31 of the measurement year with diabetes (type 1 and type 2) (see the related "Denominator Inclusions/Exclusions" field)

Numerator Description

Use codes to identify the most recent hemoglobin A1c (HbA1c) test during the measurement year. The member is numerator compliant if the most recent automated HbA1c level is less than 7.0%.

See the related "Numerator Inclusions/Exclusions" field.

Type of Evidence Supporting the Criterion of Quality for the Measure

  • A formal consensus procedure, involving experts in relevant clinical, methodological, public health and organizational sciences
  • One or more research studies published in a National Library of Medicine (NLM) indexed, peer-reviewed journal

Additional Information Supporting Need for the Measure

  • Diabetes is a complex group of diseases marked by high blood glucose (blood sugar) due to the body's inability to make or use insulin. Left unmanaged, diabetes can lead to serious complications, including heart disease, stroke, hypertension, blindness, kidney disease, diseases of the nervous system, amputations, and premature death (Centers for Disease Control and Prevention [CDC], 2014).
  • Diabetes cost the nation $245 billion in 2012: $176 billion in direct medical expenses and $69 billion in disability, unemployment and premature deaths (CDC, 2014).
  • Diabetes is the seventh leading cause of death in the United States (CDC, 2014).
  • In 2012, approximately 29 million Americans had diabetes (CDC, 2014), an increase of nearly 3 million people from 2010 (CDC, 2011).
  • Proper diabetes management is essential to control blood glucose, reduce risks of complications and prolong life. With support from health care providers, patients can manage their diabetes with self-care, taking medications as instructed, eating a healthy diet, being physically active and quitting smoking (CDC, 2014).

Extent of Measure Testing

All HEDIS measures undergo systematic assessment of face validity with review by measurement advisory panels, expert panels, a formal public comment process and approval by the National Committee for Quality Assurance's (NCQA's) Committee on Performance Measurement and Board of Directors. Where applicable, measures also are assessed for construct validity using the Pearson correlation test. All measures undergo formal reliability testing of the performance measure score using beta-binomial statistical analysis.

Denominator Inclusions/Exclusions

Inclusions
Members 18 to 64 years of age as of December 31 of the measurement year with diabetes (type 1 and type 2)

  • There are two ways to identify members with diabetes: by claim/encounter data and by pharmacy data. The organization must use both to identify the eligible population, but a member only needs to be identified by one method to be included in the measure. Members may be identified as having diabetes during the measurement year or the year prior to the measurement year.
    • Claim/Encounter Data: Members who met any of the following criteria during the measurement year or the year prior to the measurement year (count services that occur over both years):
      • At least two outpatient visits (Outpatient Value Set), observation visits (Observation Value Set), emergency department (ED) visits (ED Value Set) or nonacute inpatient encounters (Nonacute Inpatient Value Set) on different dates of service, with a diagnosis of diabetes (Diabetes Value Set). Visit type need not be the same for the two visits.
      • At least one acute inpatient encounter (Acute Inpatient Value Set) with a diagnosis of diabetes (Diabetes Value Set).
    • Pharmacy Data: Members who were dispensed insulin or hypoglycemics/antihyperglycemics on an ambulatory basis during the measurement year or the year prior to the measurement year (refer to Table CDC-A in the original measure documentation for a list of prescriptions to identify members with diabetes).

Note:

  • Members must have been continuously enrolled during the measurement year.
  • Allowable Gap: No more than one gap in enrollment of up to 45 days during the measurement year. To determine continuous enrollment for a Medicaid beneficiary for whom enrollment is verified monthly, the member may not have more than a 1-month gap in coverage.
