An increasingly elderly end-stage renal disease (ESRD) population, particularly in the United States, requires nephrologists to focus upon issues relating to palliative care [1-7]. The American Society of Nephrology (ASN) and Renal Physicians Association (RPA), for example, have sponsored evidence-based guidelines relating to withholding and withdrawing from dialysis  and a United Kingdom Expert Consensus Group published guidelines for symptom management in adults dying with chronic kidney disease .
Since nearly 20 percent of dialysis patients stop dialysis prior to death, it is likely that all nephrologists will be involved in end-of-life care. As a group, however, physicians are poorly trained in palliative care and often feel uncomfortable with the care of dying patients [10,11]. In one survey of American and Canadian physicians, for example, only approximately 40 percent of 360 nephrologists stated that they were very well prepared to make end-of-life decisions . (See "Withdrawal from and withholding of dialysis".)
Providing palliative care to patients with chronic kidney disease begins at the time of diagnosis and continues throughout the patient's life. With progression of kidney disease, palliative care assumes increasing importance with time and is integral to "good deaths." Dialysis unit staff should be involved in such care and also must recognize their responsibilities in the areas of advance care planning, pain and symptom management, and bereavement support [1,6,8,12-15]. A national survey of palliative care in the United Kingdom again demonstrated opportunities to improve this aspect of ESRD care and prompted the authors to suggest guidelines for renal palliative care initiatives .
This topic review will discuss aspects of care that typically require attention in the patient who withdraws from dialysis or chooses not to initiate dialysis. Principles of palliative care will be addressed as well as guidelines for the use of analgesia in these patients.
PRINCIPLES OF PALLIATIVE CARE
Palliative care refers to the comprehensive management of the physical, psychological, social, spiritual, and existential needs of patients and families in the setting of serious illness . The goal of palliative care is to achieve the best possible quality of life by relieving suffering, controlling symptoms, and restoring functional capacity, while maintaining sensitivity to personal, cultural, and spiritual beliefs and practices . Throughout the course of a serious illness, palliative care assumes an increasing priority over disease-directed care and eventually focuses upon the dying process .
