Awareness of chronic kidney disease (CKD) remains low in the United States. Estimates of awareness among adults with CKD are based on laboratory measures in the National Health and Nutrition Examination Survey (NHANES). Provider awareness is gauged based on diagnosis codes of patients with laboratory results that indicate CKD within a health care system.

eGFR Formula Disclaimer
At the time of the last data update in summer 2022, the race-free eGFR formula was newly recommended and impact on health outcomes is underway. To avoid inconsistent results caused by different formulae, stakeholders continued using the eGFR formula with race during this transition. Since then, comparisons have been made. The estimates for the current website launch are still based on analyses using the eGFR formula with race, however plan is to use race-free eGFR formula for the next data update and upcoming website launch in fall 2023.
