Exercise for Dialysis Patients

1. Exercise for Dialysis Patients Amanda Newberry, M.Ed. Exercise Physiologist University of Virginia Renal Services CRN Meeting November 2010

2. Objectives To provide knowledge and supporting data on benefits of intradialytic exercise To encourage incorporating exercise into routine patient care plan To provide information on beginning a unit based exercise program To describe the procedures and operations of a current unit based exercise program

3. Physical Functioning The ability of an individual to perform activities required in their daily lives. PF of dialysis patients is LOW!

4. Self-Reported Physical Functioning Scale ScoresResults from SF-36 Questionnaire 84 69 56 50 50 1. Ware et al: Health Institute; 1994

6. Measures of Physical Functioning • Short Physical Performance Battery • Gait speed (4 meters) • Sit to stand (time for 5 ) • Standing balance tests • Other measures • 6 min walk test

8. Physical Inactivity leads to… • Overall decline in physical well-being • Poor physical performance • Fluid build up in tissues • Loss of bone strength • Loss of appetite • Muscle wasting • Hypertension • Dependence • Fatigue

10. Benefits

11. Physiological Benefits • Reduced risk of cardiovascular mortality • Decreased use of antihypertensive medications • Favorable adaptation of body composition • Reduced C-reactive protein/increased albumin • Improved removal of toxins by dialysis • Improved exercise capacity • Improved blood pressure control • Improved lipid profile • Esp increased HDL and reduced TG • Increased hematocrit • Prior to EPO therapy • Improved glucose regulation

12. Psychological Benefits • Reduced subjective fatigue symptoms • Improved perception of physical functioning • Improved perception of general health • Reduced anxiety • Improved mental health • Reduced experience of bodily pain • Increased vitality • Improved psychological profile • Reduced anxiety, hostility, and depression, and increased participation in pleasant activities

13. Functional Benefits • Improved muscle strength • Increased 6-min walk distance • Reduced risk of falls in the elderly • Maintenance of independence

14. Clearance During dialysis: Urea removed from blood Urea retained in peripheral body compartments Urea and creatinine distributed in body water Muscle water content high Muscle mass = ~40-45% total body weight Much of solute mass will be held within muscles Some body tissue is unexposed to dialysis 4. Kong, et al: Nephrol Dial Transplant. 1999; 14: 2927-2931.

15. Clearance 4. Kong, et al: Nephrol Dial Transplant. 1999; 14: 2927-2931. • After dialysis: • Urea re-equilibrates and a rebound results • Limits the efficiency of dialysis • With exercise: • Muscle blood flow increases • Potential increase from 3-4ml/min per 100g to 80ml/min per 100g • More tissue mass is exposed to the dialysis treatment

16. 4. Kong, et al: Nephrol Dial Transplant. 1999; 14: 2927-2931. Improved urea Kt/V with exercise

17. Cramping • Timing of exercise • Type of exercise • Intensity of exercise Start slowly, Progress gradually!!!

18. Exercise: A Vital Sign

19. Exercise Rx Surgeon General’s report: “significant health benefits can be obtained by including a moderate amount of physical activity….on most, if not all, days of the week”.

20. American College of Sports Medicine (ACSM) “Exercise Prescription: every patient, every visit, every time” www.exerciseismedicine.org

21. Exercise is MedicineTM • Guiding principles: • Exercise and physical activity are important to health and the prevention and treatment of many chronic diseases • More should be done to address physical activity and exercise in healthcare settings • ACSM and AMA are making efforts to bring a greater focus on physical activity and exercise in healthcare settings

22. Program Implementation

23. New Program Resources Life Options Rehabilitation Advisory Council (LORAC)5 “Exercise for the Dialysis Patient” A Guide for the Dialysis Team Author: Patricia Painter, PhD Staff Responsibility to Exercise Carlson L, Carey S. ACKD Vol 6, No 2 pp172-180, 19996

24. Steps to developing an exercise program • Gaining staff support • Edu/inservice • Case presentations • Commitment to developing a program • Group input • Assurance of willingness of staff to participate • Assess available resources • Staff interest • Teamwork • Interested patients • Local programs 6. Carlson L, Carey S. ACKD, 1999

25. Steps to developing an exercise program • Develop a program • Smaller working groups (care planning, motivation/education, exercise programming) • Staff responsibilities identified • Facilitate a sense of ownership amongst staff • Start program • Start slowly (one shift, one bay, interested pts) • Progress gradually • Ongoing evaluation • CQI • Patient reassessment • Patient programs 6. Carlson L, Carey S. ACKD, 1999

26. UVA SitFit Exercise Program 8 Units 800 patients 50% patient participation 78% exercise compliance

27. UVA SitFit Exercise Program • One Exercise Physiologist • Exercise Leader at each unit • Technician or RN • Monthly QAPI Reports • Monthly Compliance Reports • Quarterly Exercise Team meetings

28. Beyond the science… • Setting expectations • Potential for patient to exercise • Motivating a non-motivated patient

29. Barriers to Exercise Sickness Fatigue Lack of equipment Lack of motivation Depression Lack of encouragement Most can be resolved through exercise!
