KEEP ObjectivesKEEP Objectives

• Identify those at risk for Chronic Kidney Disease (CKD) using inclusion criteria:– Hypertension – Diabetes – Family history in first order relatives of

hypertension, diabetes or chronic kidney disease

• To empower individuals to prevent or delay the onset of CKD or renal failure through education and appropriate disease management

Chronic Kidney Disease Is a Chronic Kidney Disease Is a Public Health Problem!Public Health Problem!

• 26 million Americans have CKD. Most don’t know it.

• The devastating consequences of CKD are End Stage Renal Disease (ESRD), which requires dialysis or transplantation, or cardiovascular disease & death.

• Early screening, diagnosis, and treatment should delay or prevent death and ESRD.

• CKD is a worldwide public health problem.

New York State Impact

• An estimated 1.2 million New Yorkers are affected by CKD.

• The Center for Disease Control (CDC) reports a 116% increase in CKD in NYS over the past decade.

• In cost related to CKD, NYS is the 4th highest state at $2.9 billion.

• 7,300 New Yorkers will advance to End Stage Renal Disease (ESRD) annually.

• The diabetic CKD prevalence rate has increased from 6.2% to 7.6% from 2000 to 2006.

• Primary Causes of ESRD– Diabetes 40.5%– Hypertension 24%

KEEP OVERVIEW

• KEEP is a free public health screening program.• It was initiated in New York City by the National

Kidney Foundation in August of 2000.• Screenings are held in all areas of the US by local

• Determines kidney function.

• Results sent to participant within 4 weeks, with a comprehensive report.

Used to determine anemia, which can be due to advanced Stages 3 to 5 or even low levels of kidney function.

The following tests are conducted on the blood specimens of KEEP participants with an eGFR below 60:

•Calcium•Phosphorus•PTH

These tests assess bone health. Abnormal results may be related to kidney disease.
