A Primary Care Approach to CKD Management
Slide 2-

Learning Objectives Facilitate timely testing and intervention in patients at-risk for chronic kidney disease (CKD). Apply appropriate clinical measures to manage risk and increase patient safety in CKD. Co-manage and refer patients to nephrology specialists, when appropriate, in order to improve outcomes in CKD.

A 50-year-old Hispanic female was diagnosed with type 2 diabetes at age 30. She has taken medications as prescribed since diagnosis. The fact that she has confirmed diabetes puts this patient at: A. Higher risk for kidney failure and CVD B. Higher risk for kidney failure only C. Higher risk for CVD only D. None of the above Case Question 1
Slide 4-

A 42-year-old African American man with diabetic nephropathy and hypertension has a stable eGFR of 25 mL/min/1.73m2. Observational Studies of Early as compared to Late Nephrology Referral have demonstrated which of the following? A. Reduced 1-year Mortality B. Increase in Mean Hospital Days C. No change in serum albumin at the initiation of dialysis or kidney transplantation D. Decrease in hematocrit at the initiation of dialysis or kidney transplantation E. Delayed referral for kidney transplantation Case Question 2

The Public Burden of CKD
Slide 7-

CKD as a Public Health Issue 26 million American affected Prevalence is 11-13% of adult population in the US 28% of Medicare budget in 2013, up from 6.9% in 1993 $42 billion in 2013 Increases risk for all-cause mortality, CV mortality, kidney failure (ESRD), and other adverse outcomes. 6 fold increase in mortality rate with DM + CKD Disproportionately affects African Americans and Hispanics NKF Fact Sheets. http://www.kidney.org/news/newsroom/factsheets/FastFacts.

Slide 15-

Improved Diagnosis… Studies demonstrate that clinician behavior changes when CKD diagnosis improves. Significant improvements realized in:1-3 Increased urinary albumin testing Increased appropriate use of ACEi or ARB Avoidance of NSAIDs prescribing among patients with low eGFR Appropriate nephrology consultation Wei L, et al. Kidney Int. 2013;84:174-178. Chan M, et al. Am J Med. 2007:120;1063-1070. Fink J, et al. Am J Kidney Dis. 2009,53:681-668.
Slide 16-

Screening Tools: eGFR Considered the best overall index of kidney function. Normal GFR varies according to age, sex, and body size, and declines with age. The NKF recommends using the CKD-EPI Creatinine Equation (2009) to estimate GFR. Other useful calculators related to kidney disease include MDRD and Cockroft Gault. GFR calculators are available online at www.kidney.org/GFR. Summary of the MDRD Study and CKD-EPI Estimating Equations: https://www.kidney.org/sites/default/files/docs/mdrd-study-and-ckd-epi-gfr-estimating-equations-summary-ta.pdf
Slide 17-

Screening Tools: ACR Urinary albumin-to-creatinine ratio (ACR) is calculated by dividing albumin concentration in milligrams by creatinine concentration in grams. Creatinine assists in adjusting albumin levels for varying urine concentrations, which allows for more accurate results versus albumin alone. Spot urine albumin-to-creatinine ratio for quantification of proteinuria New guidelines classify albuminuria as mild, moderately or severely increased First morning void preferable 24hr urine test rarely necessary
Slide 18-

Criteria for CKD Abnormalities of kidney structure or function, present for >3 months, with implications for health Either of the following must be present for >3 months: ACR >30 mg/g Markers of kidney damage (one or more*) GFR <60 mL/min/1.73 m2 *Markers of kidney damage can include nephrotic syndrome, nephritic syndrome, tubular syndromes, urinary tract symptoms, asymptomatic urinalysis abnormalities, asymptomatic radiologic abnormalities, hypertension due to kidney disease.m²

Slide 23-

Slowing CKD Progression: ACEi or ARB Risk/benefit should be carefully assessed in the elderly and medically fragile Check labs after initiation If less than 25% SCr increase, continue and monitor If more than 25% SCr increase, stop ACEi and evaluate for RAS Continue until contraindication arises, no absolute eGFR cutoff Better proteinuria suppression with low Na diet and diuretics Avoid volume depletion Avoid ACEi and ARB in combination1,2 Risk of adverse events (impaired kidney function, hyperkalemia) Kunz R, et al.

Detect and Manage CKD Complications Anemia Initiate iron therapy if TSAT ≤ 30% and ferritin ≤ 500 ng/mL (IV iron for dialysis, Oral for non-dialysis CKD) Individualize erythropoiesis stimulating agent (ESA) therapy: Start ESA if Hb <10 g/dl, and maintain Hb <11.5 g/dl. Ensure adequate Fe stores. Appropriate iron supplementation is needed for ESA to be effective CKD-Mineral and Bone Disorder (CKD-MBD) Treat with D3 as indicated to achieve normal serum levels 2000 IU po qd is cheaper and better absorbed than 50,000 IU monthly dose. Limit phosphorus in diet (CKD stage 4/5), with emphasis on decreasing packaged products - Refer to renal RD May need phosphate binders

A Balanced Approach to Nutrition in CKD: Macronutrient Composition and Mineral Content* Adapted from DASH (dietary approaches to stop hypertension) diet.*Adjust so total calories from protein, fat, and carbohydrate are 100%. Emphasize such whole-food sources as fresh vegetables, whole grains, nuts, legumes, low-fat or nonfat dairy products, canola oil, olive oil, cold-water fish, and poultry. NKF KDOQI.
