About the National Data
Data
Baseline: 7.3 percent of adults aged 18 years and over with chronic kidney disease knew they had reduced kidney function in 2013-16
Target: 10.1 percent
Methodology
Chronic kidney disease (CKD) stages 1–4 are defined as a urinary albumin-to-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 is computed using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.
Persons were considered to be aware that they have damaged kidneys or reduced kidney function if they answered "yes" to the awareness question. Persons who did not respond to the awareness question (responses of "refused" and "unknown") were excluded from the analysis.
Numerator is based on NHANES interview question and denominator is based on NHANES Mobile Examination Center laboratory testing.
History
In 2023, the original baseline was revised from 7.2 to 7.3 percent due to changes to 2021 race free, serum creatine only CKD-EPI equation used to determine estimated glomerular filtration rate (eGFR). The target was adjusted from 10.0 to 10.1 percent to reflect the revised baseline using the original target-setting method.
1. Effect size h=0.1 was chosen to correspond with 10% improvement from a baseline of 50%.
