3 3 Objectives Employ appropriate goals and management strategies for patients who are unable to proceed with rehabilitative renal replacement therapy Describe the 2 nd edition of the Shared Decision- Making in the Appropriate Initiation of and Withdrawal from Dialysis guideline Apply the guideline recommendations to cases Explain an evidence-based approach to prognostication in dialysis patients

4 4 Differing Goals for Care Mr. Higgins (not his real name) is a 67 year-old man who has been on CCPD for several years for ESRD from diabetic nephropathy. His long-standing diabetes has been complicated by severe autonomic and peripheral neuropathy, gastroparesis, blindness, and peripheral vascular disease. Over the past two years he has had multiple prolonged hospitalizations. He is severally malnourished with a serum albumin of 2.0. He is bedridden due to the diabetic involvement of his nervous system. He becomes lightheaded on sitting and cannot stand. Multiple interventions have been tried to improve his appetite and energy level with no success.

5 5 He has been offered TPN and hospitalization for rehabilitation, but the patient has declined most interventions. He wants to stay at home. His care is exhausting to his wife. The home health agency feels they have little to offer him. He has stopped coming for patient dialysis visits because transportation is so difficult. The patient, his wife, and the nephrology team all know that the patient is slowly dying. He wants to die at home. He does not want to stop dialysis even though he knows his health is rapidly declining. What can be done to help Mr. Higgins and family?

6 6 Three Points Mr. Higgins goals for care are different than those of most dialysis patients. Patient-centered care for him would look different than for another dialysis patient. There is an available approach to achieve his goals for treatment, but it is not yet widely used in dialysis units.

7 Evidence-based 10 adult recommendations 9 pediatric recommendations Rationales and strategies for implementation for each Tool kit of validated instruments Available from RPA online store

8 Different Treatment Goals for ESRD Patients New in the guideline is the identification of distinctly different treatment goals for ESRD patients based on their overall condition and preferences: 1.Patients who choose aggressive therapy with dialysis w/o limitations on other treatments-rehabilitative RRT 2.Patients with a poor prognosis who choose dialysis but with limitations on other treatments such as CPR, intubation, and mechanical ventilation because they want to balance life prolongation and comfort 3.Patients who decline dialysis and prefer that the primary goal of care be their comfort-active medical management 8

9 Providing Effective Palliative Care Recommendation No. 9 To improve patient-centered outcomes, offer palliative care services and interventions to all AKI, CKD, and ESRD patients who suffer from burdens of their disease. Recommendation No. 10 Use a systematic approach to communicate about diagnosis, prognosis, treatment options, and goals of care. 9

10 10 Palliative Care End-of-Life/ Hospice Care Relationship between Palliative Care and EOLC

11 Whats New in the Guideline The poor prognosis of some elderly stage 4 & stage 5 chronic kidney disease patients, many of whom are likely to die prior to initiation of dialysis or for whom dialysis may not provide a survival advantage over medical management without dialysis An online calculator to estimate prognosis in ESRD patients The identification of distinctly different treatment goals for ESRD patients based on their overall condition and preferences The frequent prevalence of cognitive impairment in dialysis patients 11

12 Whats New in the Guideline Recognition of advance care planning as the preferred approach for decision-making for patients who lose decision-making capacity The under treatment of pain in dialysis patients The underutilization of hospice in dialysis patients Strategies to assist nephrologists with communication challenges regarding prognosis and treatment options Recommendations with regard to pediatric dialysis decision-making 12

13 10 GUIDELINE STATEMENTS: 6 TOPICS Establishing a shared decision- making relationship #1 Informing patients #2,#3 Facilitating advance care planning #4 Making decisions about initiating and discontinuing dialysis #5,#6 Resolving conflicts about which dialysis decisions to make #7,#8 Providing effective palliative care #9,#10

14 A 40 year-old woman with ESRD from diabetic nephropathy who had started dialysis 3 months earlier was found down and unresponsive at home. EMS was called. They noted a blood sugar of zero. The patient was given D50 but did not respond. She was transported to the local ED where a repeat blood sugar was undetectable. The patient was again given an amp of D50 and started on a D10W drip. Despite the drip, over the next 24 hours the patient required additional boluses of D50 to raise her low blood sugar. The patient did not awaken. Neurology consultants diagnosed an anoxic encephalopathy from prolonged hypoglycemia. 14

15 Workup for the patients coma included a CT scan which did not show an acute intracranial process and an EEG which showed diffuse generalized slowing with no response to photic, auditory, and tactile stimuli. EEG findings were suggestive of a diffuse encephalopathic pattern due to hypoxia, hypoglycemia, metabolic disturbance, or a toxic or infectious etiology. Despite her mothers coma, the daughter who was appointed her healthcare surrogate continued to request all possible treatment including dialysis and wound care for large necrotic ulcers on both legs from calciphylaxis. 15

16 The patients exam did not change over the subsequent six weeks nor did the EEG findings. The neurology service thought the patient had a very poor prognosis but said it could take up to six months or longer to be sure that patient would not wake up. The treating nephrologist did not think that dialysis should be continued because of the patients profound neurologic impairment such that she lacked signs of thought, sensation, purposeful behavior, and awareness of self and environment. 16

17 Despite a series of meetings in which the patients diagnosis and prognosis were explained in complete detail to the daughter and family by the nephrologist and the palliative care consultant, the daughter insisted that her mother continue to be dialyzed. Other family members thought that the patient would not want to continue on dialysis in her present condition, but the daughter became quite emotional and said that it was up to her to fight for her mother. No other nephrologist in the hospital was willing to assume care of the patient and continue dialysis. 17

18 Audience Response Slide Should you… 1.Continue dialysis as the daughter requests 2.Stop dialysis because the patient is comatose 3.Request an ethics consultation 4.Seek a court order to stop dialysis 18

19 An ethics consultation was requested, and the ethics committee agreed with the recommendation to discontinue dialysis. When the daughter was given a weeks notice and informed that the dialysis would be discontinued at the end of the seventh week of hospitalization because the patient remained in a coma, she contacted an attorney. What should the treating nephrologist do? 19

20 Patients with decision-making capacity, who being fully informed and making voluntary choices, refuse dialysis or request that dialysis be discontinued PATIENT SAYS NO DIRECTLY Patients who no longer possess decision-making capacity who have previously indicated refusal of dialysis in an oral or written advance directive PATIENT SAYS NO INDIRECTLY Patients who no longer possess decision-making capacity and whose properly appointed legal agents/surrogates refuse dialysis or request that it be discontinued PROXY SAYS NO Patients with irreversible, profound neurological impairment such that they lack signs of thought, sensation, purposeful behavior, and awareness of self and environment. 1,2 PROVIDERS SAY NO 1 J Am Soc Nephrol 1994;4(11): N Engl J Med 1990;322(14): APPROPRIATE TO SAY NO

21 Resolving Conflicts about Which Dialysis Decisions to Make Recommendation No. 8 Establish a systematic due process approach for conflict resolution if there is disagreement about what decision should be made with regard to dialysis. 21

22 Systematic Approach to Resolving Conflict between Patient/Family and Kidney Care Team RPA guideline for Shared Decision-Making, 2 nd ed

23 Systematic Approach to Resolving Conflict between Patient/Family and Kidney Care Team RPA guideline for Shared Decision-Making, 2 nd ed

24 Audience Response Slide What should the nephrologist do now? 1.Just keep dialyzing the patient 2.Attempt to transfer care within the hospital 3.Attempt to transfer care to another hospital 4.Stop dialysis without further discussion 24

25 Conflict Resolution 25 In following the process, the treating nephrologist contacted nephrologists throughout the state. No other nephrologist and hospital was willing to accept the patient and dialyze her. The daughters attorney sought a court order to force the hospital to continue dialyzing the patient. The judge ruled that the hospital only needed to continue dialysis for one more week to see if the family could find a nephrologist to dialyze the patient. He was influenced in his ruling by 1) the clinical practice guideline recommending against dialysis for a person in the patients condition, and 2) there was no other nephrologist who could be found who was willing to dialyze the patient.

32 Reason to Consider Age > Most older members of this cohort [209,622 VA patients with stage 3 to 5 CKD], especially those 75 years, were far more likely to die than develop ESRD, even when their eGFR was severely reduced (15 to 29 ml/min per 1.73 m 2 ).

36 patient- specific estimates of prognosis Recommendation No. 3: Informing patients All patients with AKI, stage 5 CKD or ESRD should receive patient- specific estimates of prognosis. 2 or more Poor prognosis 1,2,3 1.> 75 years 2.High comorbidity scores (No to Surprise Question) A.(e.g., modified Charlson Comorbidity score > 8) 3.Marked functional impairment A.(e.g., Karnofsky performance status score < 40) 4.Severe chronic malnutrition A.(e.g., serum albumin level < 2.5 g/dL using the bromcresol green method). Patients in this population should be informed: 1.Dialysis may not confer a survival advantage or improve functional status over medical management without dialysis 2.Dialysis entails significant burdens which may detract from their quality of life. 1 Arnold RM, Zeidel ML. Dialysis in frail elders--a role for palliative care. N Engl J Med 2009;361(16): Murtagh FE, Marsh JE, Donohoe P, Ekbal NJ, Sheerin NS, Harris FE. Dialysis or not?

37 Informed Consent for Elderly CKD Patients SHOULD INCLUDE: Patients with this level of illness more likely to die than live long enough to progress to ESRD 1 The majority of patients in their condition die or succumb to significant functional decline during their first year on dialysis 2 Dialysis may not confer a survival advantage Surgery and complications for vascular access or peritoneal access placement Adverse physical symptoms on dialysis --dizziness, fatigue, and cramping, and a feeling of unwellness after dialysis. Travel time and expense to and from dialysis Long hours spent on dialysis reduction in the time available for physical activity. Life on dialysis entails burdens likely to detract from their quality of life Invasive and costly tests, procedures, and hospitalizations. Unnecessary medicalization of death 1 J Am Soc Nephrol 2007;18(10): J Am Soc Nephrol 2003;14(4):

38 – Coverage Under the Hospice Benefit (Rev. 1, ) If the patients terminal condition is not related to ESRD, the patient may receive covered services under both the ESRD benefit and the hospice benefit. A patient does not need to stop dialysis treatment to receive care under the hospice benefit. Consequently, hospice agencies can provide hospice services to patients who wish to continue dialysis treatment. Think Mr. Higgins
