Early Identification and Screening for Chronic Kidney Disease | CKD Toolkits | WCHQ

When and How to Screen

‍Screen early and often when a patient has type 2 diabetes and/or hypertension

‍Screen with both uACR and eGFR

‍Screen when patients have risk factors for CKD: type 2 diabetes, hypertension, age> 60, obesity, family history of kidney disease, history of acute kidney injury (AKI), history of tobacco use, social drivers (i.e.: poverty and/or food insecurity)

CKD can be described as an accelerator of chronic disease^7. Identifying CKD in early stages of illness progression is important because the risk renal failure and cardiovascular complications is reduced¹⁰. More than 1 in 7 US adults are estimated to have CKD and as many as 9 in 10 do not know they have it yet. CKD does not necessarily cause symptoms or illness at the earliest, preventable stage, so the only way to know a patient has CKD is to test their kidney function¹¹. The American Diabetes Association recommends screening all patients with diabetes for CKD and the National Kidney Foundation recommends screening for CKD in all patients with risk factors including diabetes, hypertension, family history of kidney disease, age 60 or older, Race/U.S. ethnic minority status status (i.e.: AfricanAmericans, Hispanics, Asians/Pacific Islander, Native American). Focusing on screening patients with risk factors annually, or more frequently depending on test results, to identify kidney disease early allows for the best possible prognosis and ability to intervene in the course of this chronic illness.

Estimated Glomerular Filtration Rate eGFR

eGFR, a blood test, is the optimal way to measure kidney function and understand how the kidneys are functioning and cleaning toxins from the blood.

Diagnose CKD

‍Use eGFR and uACR to diagnose

‍eGFR can be normal where uACR is severely increased

uACR can be normal where eGFR is severely decreased

KDIGO Heat Map

Kidney Disease Improving Global Outcomes (KDIGO) has created a heat map for clinicians to compare eGFR and uACR to diagnose and stage CKD. The heat map helps clinicians to understand patient risk, if referrals are required and help patients understand how CKD is progressing or reversing.
