CKD-6.2 Data Details

Expand All

CKD-6.2 Increase the proportion of adults aged 50 years and over with chronic kidney disease who currently take statins to lower their blood cholesterol

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Health and Nutrition Examination Survey
Changed Since the Healthy People 2020 Launch: 
Yes
Measure: 
percent (age adjusted—see Comments)
Baseline (Year): 
21.6 (2001–06)
Target: 
25.6
Target-Setting Method: 
Minimal statistical significance
Target-Setting Method Justification: 
Using minimal statistical significance would target a reduction in the measure of about 5 percentage points (rather than about 2 percentage points lower using the 10% improvement method).
Numerator: 

Number of persons aged 50 years and over with chronic kidney disease stages 1-4 who reported currently taking statins to lower their blood cholesterol

Denominator: 

Number of persons aged 50 years and over with chronic kidney disease stages 1-4

Comparable Healthy People 2010 Objective: 
Not applicable
Questions Used to Obtain the National Baseline Data: 

    From the 2001-2006 National Health and Nutrition Examination Survey:

    [NUMERATOR:]

    To lower (your/his/her) blood cholesterol, (have/has) (you, SP) ever been told by a doctor or other health professional…to take prescribed medicine?

    1. Yes
    2. No
    3. Refused
    4. Don't know

    [If yes] (Are you/Is SP) now following this advice to take prescribed medicine?

    1. Yes
    2. No
    3. Refused
    4. Don't know
Data Collection Frequency: 
Periodic
Methodology Notes: 

    Chronic kidney disease (CKD) stages 1-4 are defined as a urinary albumin/creatinine ratio (ACR) >30 mg/g (single measurement) or estimated glomerular filtration rate (eGFR) between 15 and 59 ml/min/1.73 m². The eGFR was computed using the Modification of Diet in Renal Disease (MDRD) study equation.

    Abnormal lipid values are defined in the Adult Treatment Plan III guidelines developed by the Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults.

    Age Adjustment Notes: 

    This Indicator uses Age-Adjustment Groups:

    • Total: 50-64, 65+
    • Sex: 50-64, 65+
    • Race/Ethnicity: 50-64, 65+
    • Educational Attainment: 50-64, 65+
    • Family Income (percent poverty threshold): 50-64, 65+
    • Country of Birth: 50-64, 65+
    • Disability Status: 50-64, 65+
    • Health Insurance Status: 50-64
    • Marital Status: 50-64, 65+
    • Veteran Status: 50-64, 65+
    • Obesity Status: 50-64, 65+

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2015, the objective text was changed from “Reduce the proportion of persons with chronic kidney disease who have elevated lipid levels” to “Increase the proportion of persons aged 50 year and older with chronic kidney disease who currently take statins to lower their blood cholesterol.” The measure was changed from the proportion of persons with CKD and abnormal lipid values or reported prescription for statins to the proportion of persons with CKD and reported prescription for statins. The rationale for this change was to make the objective consistent with recommended patient care guidelines by the Kidney Disease Improving Global Outcomes Workgroup. Consequently, the baseline was revised from 28.4% (1999-2004) to 21.6% (2001-2006). The target-setting method was also revised from 10 percent improvement to minimal statistical significance and the target was adjusted from 25.4% to 25.6% to reflect the revised baseline.
