National Numerator
Subset of the denominator who responded "Yes" to each of the four survey items related to receipt of diabetes services.
Comments
The criteria for selecting the diabetes population from MEPS and the methodology for calculating the diabetes composite measure have changed over time. Reported rates may not be comparable with those found in prior years' editions of the NHQR and NHDR. The composite measure for this year's edition of the reports, for example, contains four measures (two or more hemoglobin A1c measurements, dilated eye examination, foot examination, and flu shot within the calendar year), whereas the composite measure for the 2010 reports contained three measures (at least one hemoglobin A1c measurement, dilated eye examination, and foot examination within the calendar year).
The method for defining the numerator and denominator for the eye exam component of this composite measure changed beginning with the 2008 edition of the NHQR and NHDR; rates may not be comparable with those reported in earlier editions.
Cases with any missing values for the measures that make up the composite were excluded from the analysis.
The entries for each of the four components of the composite measure provide further details about the individual survey questions.

Comments
Short-term complications include ketoacidosis, hyperosmolarity, and coma. Long-term complications include renal, eye, neurologic, circulatory, and other unspecified. Excludes obstetric admissions and transfers from other institutions.
Rates are adjusted by age and gender using the total U.S. resident population for 2000 as the standard population; when reporting is by age, the adjustment is by gender only; when reporting is by gender, the adjustment is by age only.
Although not all States participate in the HCUP database, NIS is weighted to give national estimates using weights based on all U.S. community, nonrehabilitation hospitals in the American Hospital Association Annual Survey Database.
SID includes a powerful set of hospital databases from data organizations in participating States. SID contains the universe of the inpatient discharge abstracts in participating States, translated into a uniform format to facilitate multi-State comparisons and analyses. Together, SID encompasses about 90% of all U.S. community hospital discharges. SID contains a core set of clinical and nonclinical information on all patients, regardless of payer, including people covered by Medicare, Medicaid, and private insurance, as well as uninsured people. In addition to the core set of uniform data elements common to all SID, some databases within SID include other elements, such as the patient's race.
The SID disparities analysis file is designed to provide national estimates on disparities using weighted records from a sample of hospitals from the following 31 States: Arizona, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Missouri, Nevada, New Hampshire, New Jersey, New York, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, Virginia, Vermont, Wisconsin, and Wyoming.
