    21. 21. A Recent Case in Point Mrs. G is a 78 year old woman was referred by her primary MD for evaluation of CKD with worsening function. She had a 20 year history of DM complicated by PVD, requiring toe amputation. She had multiple other comorbid illnesses including hypertension, cryptogenic cirrhosis with liver failure, pancytopenia, CHF, and a history of massive GI bleeding from esophageal varices a year ago.
    22. 22. A Recent Case in Point The patient required assistance with all ADL except feeding and was residing in a NH. She had only a sister whom she named her medical power of attorney representative. She had decision-making capacity. Lab data revealed an estimated GFR of 15 ml/min, and a serum albumin of 2.8 mg/dl. It was obvious she would progress to ESRD soon. The patient made it clear that despite her poor prognosis, she wanted hemodialysis when needed.

    30. 30. Medical Indications Diagnostic and therapeutic interventions (e.g., dialysis) are deemed to be indicated if the expected medical benefits justify the risks.
    31. 31. Recommendation #1: Shared Decision-Making A patient-physician relationship that promotes shared decision-making is recommended for all patients with either ARF or ESRD. Participants in shared decision-making should involve at a minimum the patient and the physician. If a patient lacks decision-making capacity, decisions should involve the legal agent. With the patient’s consent, shared decision-making may include family members or friends and other members of the renal care team.
    32. 32. Recommendation #2: Informed Consent or Refusal Physicians should fully inform patients about their diagnosis, prognosis, and all treatment options, including: 1) available dialysis modalities, 2) not starting dialysis and continuing conservative management which should include end-of-life care, 3) a time-limited trial of dialysis, and 4) stopping dialysis and receiving end-of-life care. Choices among options should be made by patients or, if patients lack decision-making capacity, their designated legal agents. Their decisions should be informed and voluntary…
    33. 33. Recommendation #3 Estimating Prognosis To facilitate informed decisions about starting dialysis for either ARF or ESRD, discussions should occur with the patient or legal agent about life expectancy and quality of life.… All patients requiring dialysis should have their chances for survival estimated, with the realization that the ability to predict survival in the individual patient is difficult and imprecise. The estimates should be discussed with the patient or legal agent, patient’s family, and among the medical team.

    42. 44. Recommendation #8 Time-Limited Trials For patients requiring dialysis, but who have an uncertain prognosis, or for whom a consensus cannot be reached about providing dialysis, nephrologists should consider offering a time-limited trial of dialysis.
    43. 45. The Daughter Rescinded the DNR Order A 65-year-old widow with a history of DM, hypertension, and TIA was started on HD for DN. She was cognitively intact, cooperative, compliant, and able to deal with her diagnosis of ESRD. She used the Wheelchair Van Service because she did not want to be a burden. She had family support, primarily from her daughter. Two years after starting dialysis, she signed a DNR order and a Health Care Proxy, naming her daughter. About 2 weeks later, a CT scan done for mental status changes revealed multiple areas of infarction. Subsequently, she had numerous admissions to the hospital for fluid overload. Dialysis was increased to 4 times a week. Her mental status deteriorated further, and she was transferred to a NH.
    44. 46. Subsequently, she was noted to come from the NH to the dialysis facility very agitated. She would upset other patients. She became progressively problematic, and medications were tried to control her inappropriate yelling and screaming, to no avail. She was transferred to the hospital unit where she could be treated in isolation and observed more closely. She was starting to get out of her chair during treatments and pull out dialysis needles. Her daughter was repeatedly informed of her behavior, but her response was to rescind the DNR order.
    45. 47. The patient’s transfer to the hospital unit angered the daughter; she did not accept that it was in the patient’s best interest. The patient became more demented. She refused to eat; she lost 60 lbs down to 70 lbs. The daughter avoided meetings to discuss long-range planning. Yet she made it clear that she did not wish to stop dialysis. She asked about a feeding tube to increase the patient’s weight. The patient had no swallowing or GI problems to justify PEG placement. The patient continued to do poorly and died 5 years after starting dialysis and 14 months after becoming incapacitated . Case Courtesy of Rocco C. Venuto, MD
    46. 48. The Daughter Rescinded the DNR Order <ul><li>Medical Indications </li></ul><ul><ul><li>Dialysis – Recommendation No. 7 applies </li></ul></ul><ul><ul><li>CPR - <5% chance of survival – ESRD, strokes, dementia, malnutrition </li></ul></ul><ul><li>Patient Preferences </li></ul><ul><ul><li>No CPR – failure to respect patient autonomy </li></ul></ul><ul><ul><li>AD </li></ul></ul><ul><ul><ul><li>Daughter is proxy </li></ul></ul></ul><ul><ul><ul><li>Wishes re: withdrawal of dialysis unknown </li></ul></ul></ul>
    47. 49. Recommendation #7 Special Patient Groups It is reasonable to consider not initiating or withdrawing dialysis for patients with ARF or ESRD who have a terminal condition from a nonrenal cause or whose medical condition precludes the technical process of dialysis.
    48. 50. Recommendation #5 Advance Directives The renal care team should attempt to obtain written advance directives from all dialysis patients. These advance directives should be honored.
    49. 51. Failure of Advance Care Planning to Elicit Patients’ Preferences for Withdrawal From Dialysis Patients who had completed a living will and proxy were most likely to have discussed EOLC, but stopping dialysis was the least often discussed intervention, even in this patient subset. Sixty-nine percent had discussed MV; 55%, tube feedings; 43%, CPR; and only 31% had discussed stopping dialysis (all P < 0.001). Although withdrawal from dialysis is relatively common, it is rarely discussed in advance care planning by dialysis patients. Dialysis unit staff and nephrologists should address issues involving withdrawal from dialysis with their chronic dialysis patients. Am J Kidney Dis 1999; 33: pp 688-693
    50. 52. The Daughter Rescinded the DNR Order <ul><li>QOL </li></ul><ul><ul><li>Multiple admissions for fluid overload </li></ul></ul><ul><ul><li>Agitation </li></ul></ul><ul><ul><li>Severe dementia with cachexia </li></ul></ul><ul><ul><li>Failure to thrive </li></ul></ul>
    51. 53. The Daughter Rescinded the DNR Order <ul><li>Contextual </li></ul><ul><ul><li>Daughter ethically and legally ought not override patient’s wishes </li></ul></ul><ul><ul><li>NY law </li></ul></ul><ul><ul><li>Other patients in unit – use of sitter </li></ul></ul><ul><ul><li>Daughter’s emotional and spiritual needs </li></ul></ul>
    52. 54. Emotional and Spiritual Issues “ I am convinced that what really makes these decisions ‘hard choices’ has little to do with the medical, legal, ethical, or moral aspects of the decision process. The real struggles are emotional and spiritual. People wrestle with letting go. These are decisions of the heart, not just the head.” Chaplain Hank Dunn, Hard Choices for Loving People, 4 th ed. , 2002
    53. 55. Spiritual Issues in Withdrawal of Dialysis Once the treatment is no longer medically indicated, the real issue is whether the patient or family (or physician) can “let go.” “ Those who choose such life-prolonging treatments for failing patients do so primarily out of an inability to let go and not out of moral necessity or medical appropriateness.” Chaplain Hank Dunn, Hard Choices for Loving People, 4th ed .,2002
    54. 56. What should you do? <ul><li>Not allow the daughter to rescind the patient’s DNR order to respect patient autonomy </li></ul><ul><li>Require the daughter to sit with the patient during treatments </li></ul><ul><li>Ask the daughter what the mother would want if she were able to say </li></ul><ul><li>Instruct the daughter on her ethical and legal role as durable power of attorney for health care </li></ul><ul><li>Provide support to the daughter </li></ul>
    55. 57. <ul><li>A 78 yr old woman presented with a 3 day hx of increasing SOB due to pulmonary edema. She had CKD with a serum Cr of 12. CXR showed a large R hilar shadow suggestive of carcinoma of the lung. She received hemodialysis pending work-up. Investigations showed squamous cell carcinoma of the R lung; she was referred for radiotherapy. </li></ul><ul><li>  </li></ul><ul><li>With dialysis her dyspnea regressed, and she felt well. There were no symptoms from the carcinoma. She requested to continue dialysis so that she could visit her extended family and tidy her affairs. She said she would wish to stop dialysis once she developed symptoms from the cancer. After 7 wks of dialysis she developed dyspnea and pain related to her cancer. She withdrew from dialysis and received palliative care until her death. </li></ul>Short-term Benefit in a Terminally Ill Patient
    56. 58. Reasons to Dialyze Terminally Ill Patients <ul><li>Short-term benefit for competent patient </li></ul><ul><li>Time-limited trial of dialysis to help patient and family understand burdens of treatment </li></ul>
    57. 59. There is an option for ESRD patients who choose to stop or not to start dialysis: continued palliative care.
    58. 60. Recommendation #9 Palliative Care All patients who decide to forgo dialysis (or for whom such a decision is made) should receive continued palliative care. With the patient’s consent, persons with expertise in such care, such as hospice health care professionals, should be involved in managing the medical, psychosocial, and spiritual aspects of end-of-life care for these patients. Patients should be offered the option of dying where they prefer including at home with hospice care. Bereavement support should be offered to patients’ families.
