Description:Rationale & Objective:
Persons with chronic kidney disease (CKD) are often unaware of their disease status. Efforts to improve CKD awareness may be most impactful if focused on persons at highest risk of progression to kidney failure.
Study Design:
Serial cross-sectional surveys.
Setting & Participants:
Non-pregnant adults (age ≥20 years) with CKD glomerular filtration rate categories 3–4 (G3-G4) who participated in the National Health and Nutrition Examination Survey from 1999–2016 (n=3,713).
Predictor:
5-year kidney failure risk, estimated by the Kidney Failure Risk Equation (KFRE). Predicted risk was categorized as minimal (<2%), low (2%-<5%), intermediate (5%-<15%), or high (≥15%).
Outcome:
CKD awareness, defined by answering “yes” to the question, “Have you ever been told by a doctor or other health professional that you had weak or failing kidneys?”.
Analytical Approach:
Prevalence of CKD awareness was estimated within each risk group using complex sample survey methods. Associations between KFRE risk and CKD awareness were assessed using multivariable logistic regression. CKD awareness was compared with awareness of hypertension and diabetes over the same time period.
Results:
In 2011–2016, unadjusted CKD awareness was 9.6%, 22.6%, 44.7%, and 49.0% in the minimal, low, intermediate, and high risk groups respectively. In adjusted analyses, these proportions did not change over time. Awareness of CKD, including among the highest risk group, remains consistently below that of hypertension and diabetes and awareness of these conditions did increase over time.
Limitations:
Imperfect sensitivity of the “weak or failing kidneys” question for ascertaining CKD awareness.
Conclusions:
Among adults with CKD G3-G4 who have 5-year estimated risks of kidney failure of 5%- <15% and ≥15%, approximately half were unaware of their kidney disease, a gap that has persisted nearly two decades.
