1 Using Physician Extenders to Create a CKD Clinic Theresa Becker, MSN, APNP Midwest Nephrology Assoc. Chronic Kidney Disease Clinic

2 CKD Clinic The ideas of: Linking CKD Clinics & Anemia Management Programs Using physician extenders in a multidisciplinary approach Are not new!

3 CKD Clinic ADEPT Clinic Arizonia Disease Education Prevention & Treatment Started as an anemia management clinic but soon developed into a CKD Clinic Patients are referred to the Vascular Access Program when GFRs are 25-30 mL/min. Curtis C, Yee B. The process of implementing a CKD Clinic Nephrology News & Issues. 2005;19:53-54.

4 CKD Clinic SHAPE UP Program Staging & Smoking Cessation Hypertension, Hyperglycemia, Hyperlipidemia, Hyperphosphatemia, Hyperparathyroidism, Hyperkalemia, & Hypervolemia Anemia Proteinuria Evaluation for KRT Undo nephrotoxins Preservation of veins & Patient education Gnanasekaran I, Kim S, Dimitrov V, Soni A. SHAPE UP-A management program for chronic kidney disease Dialysis & Transplantation. 2006;35: 294-302.

5 CKD Clinic One step further : A study by Curtis et al. suggested that even after appropriate & timely referral to a nephrologist, there is additional value of a multidisciplinary team approach in optimizing both short and long term patient outcomes. Curtis BM, Ravani P, Malberti F, et al. The short and long term impact of multi- disciplinary clinics in addition to standard nephrology care on patient outcomes. Nephrol Dial Transplant. 2005;20:147-154.

7 CKD Clinic Components of the CKD Care Plan GFR < 60 ml/min. HTN Anemia Nutritional Status/DM Bone/Mineral Metabolism Neuropathy Functioning & Well-being Delaying Progression of CKD

8 CKD Clinic Components of the CKD Care Plan GFR < 30 ml/min. Review Modality Options Preparation for chosen option Transplant referral GFR < 15 ml/min. Tour Clinic Monitor for ESRD signs & symptoms

9 CKD Clinic CKD Patient Education Topics CKD and consequences; anemia and bone disease Common medications used in CKD Avoidance of nephrotoxic agents KRT Modalities Arm Preservation for HD access, Access placement & care of site Healthy living

10 CKD Clinic Access Teaching Pre AV access: Evaluation for appropriate arm such as vein mapping and instruction on saving that arm. Post AV access: Care of the site, exercising the access, and monitoring its development as well as instruction on its future use.

13 CKD Clinic Vascular Access Record Stage 4 (GFR < 30 ml/min): Surgical consult should be for AVF Only. Instruct Patient to Preserve Veins of Non- Dominant or Appropriate Arm Obtain Vein Mapping KDOQI Benchmark: AVF placement of > 65% for prevalent patients.

Clinical Management of Chronic Kidney Disease. Cadido, OK: Professional Communications, Inc.; 2006:185-208.

23 ESA Agents Epoetin alfa Dose (Units/week) Darbepoetin alfa Dose (mcg/week) < 2,5006.25 2,500 to 4,99912.5 5,000 to 10,99925 11,000 to 17,99940 18,000 to 33,99960 34,000 to 89,999100 > 90,000200 Aranesp Package Insert Amgen®

24 ESA Agents Side Effect Profile HTN and Headaches Myalgias Diarrhea Contraindications Uncontrolled HTN Known hypersensitivity to the active substance or any of the excipients

25 ESA Agents FDA Black Box Warning Issued 3/9/07 Use the lowest dose of ESA that will gradually increase the Hgb concentration to the lowest level sufficient to avoid the need for RBC transfusion. ESAs increase the risk for death and serious CV events when administered to target a Hgb > 12 gm/dL.

26 ESA Agents RPA Renal Physicians Association Risks and benefits must be on individual patient basis Evidence based Hgb targets are helpful and should be reintroduced May lead to unacceptably low Hgb levels AAKP American Association of Kidney Patients Warning may be confusing to patients & providers Supports targeting Hgbs between 11 and 12 Lower Hgb lead to concerns regarding QOL

27 ESA Agents Epoetin alfa (Procrit) Single-Dose Preservative Free Vials 2,000 units, 3,000 units, 4,000 units, 10,000 units, 40,000 units/1 mL Multi-Dose Preserved Vials 20,000 units/1 mL 20,000 units/2 mL

30 ESA Utilization Guidelines Hgb Level of < 11.0 gm/dL within 30 days T. Sat. and/or Ferritin within 30 to 90 days Serum creatinine within 30 days Patients weight in kilograms ESA Dose per kilogram Erythropoietin level is NOT recommended

31 ESA Utilization Guidelines Target Hgb at or above 11.0 gm/dL Caution when intentionally maintaining Hgb > 13.0 gm/dL Monitor Hgb minimum of every 30 days Target Ferritin > 100 ng/mL and T. Saturation > 20% Monitor Iron Indices Quarterly

32 ESA Utilization Guidelines Dose Adjustments If Hgb increases by > 2 gm/dL per 4 weeks and/or Hgb level > 12 gm/dL, decrease dose by 20 to 25% If Hgb level is increasing < 1 gm/dL per 4 weeks, increase dose by 20 to 25%

33 ESA Utilization Guidelines Dose Adjustments 20 to 25% dose adjustments may be achieved by: Altering the ESA dose Altering the time interval between injections

34 ESA Utilization Guidelines Dose Adjustments Increases in dose should not be made more frequently than once a month. Avoid holding doses to avoid marked drop in ESA sensitive RBC precursors and the seesaw effect of Hgb poor response pattern.

35 ESA Utilization Guidelines Dose Adjustments More frequent Hgb &/or iron indices monitoring may be necessary when: Recent bleeding or surgery Post hospitalization Post IV iron course Periods of ESA hypo-response

36 ESA Utilization Guidelines ESA Resistance Infection/Inflammation Blood Loss, Guiac Positive Stools Hyperparathyroidism B12, Folate Deficiencies Sickle cell, Thalacemias Multiple Myeloma/Malignancy ACE Inhibitor Use

37 ESA Utilization Guidelines Dose Adjustments Recent data indicates Hgb levels can be maintained with every two week epoetin alfa dosing and monthly darbepoetin alfa dosing. Benefits include increased staff productivity and patient satisfaction/compliance. Moore T., Chookie S. Extended dosing od darbepoetin alfa in patients with chronic kidney disease not on dialysis: A review of recent data. Journal of ANNA 2005;32:399-407.

38 ESA Utilization Guidelines Medicare considers doses exceeding 90,000 units per week for epoetin alfa or 200 mcg per week for darbepoetin alfa to be rarely reasonable and necessary. Medical justification for doses exceeding these amounts should be documented in the patients record.

40 Hemoglobin Monitoring HemoCue vs. Lab Draw HemoCue Analyzer utilizes an optical measuring microcuvette. It provides nearly instantaneous Hgb results with very good accuracy. Traditional Lab Draw may be used. However, it will require another appointment or extended patient visit while awaiting lab results.
