Renal palliative care.

Patients with chronic kidney disease have a shortened life expectancy and carry a high symptom burden. Clinicians need sophisticated expertise in pain and symptom management and skills in communication to meet the many needs of this population. This article reviews the literature and discusses prognosis, ethical and legal considerations, symptoms, treatment, and end-of-life issues. The field of nephrology is shifting from an exclusive focus on increasing survival to one that provides greater attention to quality of life. There is an opportunity to integrate many of the advances of palliative medicine into the comprehensive treatment of these patients.

The family perspective of ESRD deaths.

BACKGROUND: Nephrologists need to become more aware of how patients die. METHODS: Families of patients who died after receiving dialysis at 5 New England nephrology clinics were contacted and informed about the study. Postal questionnaires were completed 6 to 10 weeks after deaths to elicit the family members' perspectives. The tool inquired about quality of dying, site of death, advance care preferences, whether dialysis was discontinued, and terminal symptoms. RESULTS: There were 188 deaths, and 86 completed questionnaires (46%) were returned. The majority (64%) of family members believed that the patient had a peaceful death, followed by those who were unsure (24%), and those who thought the death was not peaceful (12%). Most deaths took place in institutional settings (56% in the hospital and 14% in nursing homes), and one quarter (27%) of the deaths occurred at home. Whereas some respondents perceived that patients preferred treatment to primarily extend life (28%), more believed that relieving pain (49%) was of greater importance, and the balance (24%) were unsure. Three quarters of the patient population were observed to be in pain during their last week of life. Pain was assessed as being extremely or moderately severe in more than 90% of patients. The second most distressing symptom was weakness or fatigue, followed by dyspnea, gastrointestinal problems, anxiety, and depression. There was significantly less likelihood of pain in the last week of life for patients who died at home compared with those who died in an institution. CONCLUSION: Nephrologists need to explore new ways to improve symptomatic treatment and minimize suffering of dying dialysis patients. These findings are the first step in benchmarking the prevalence and severity of terminal symptoms.

The long-term impact of dialysis discontinuation on families.

BACKGROUND: Little is known about the long-term psychological impact of stopping life support treatments on surviving loved ones. OBJECTIVE: The authors sought to determine if there was an increase in pathologic grief in family members left behind after deaths that followed dialysis discontinuation. DESIGN: Phone interviews were used to collect data on demographics, attitudes, and families' comfort levels with the decision to withdraw dialysis. The Impact of Event Scale was administered to assess adaptation and stress levels. Avoidance and Intrusiveness subscales were calculated and associations with other survey data were examined using chi2 tests and analysis of variance (ANOVA). SETTING/SUBJECTS: The authors contacted families in New England who had previously participated in the Baystate Dialysis Discontinuation Study. MEASUREMENTS/RESULTS: Twenty-six family members (66% of the original study sample) were interviewed approximately 55 months after patient deaths. There was a low overall level of distress and the Avoidance subscale had insufficient variability for analysis. Intrusiveness was highest for spouses and primary caregivers. Only one respondent remembered the death as having been "bad," although 62% of patients were recalled as having suffered distressing symptoms in their last days. In ascending order of importance, respondents characterized good deaths as involving mental alertness, occurring at home, taking place while asleep, being peaceful, happening in the company of loved ones, and being painless or largely painfree. Almost all of the families reported becoming more comfortable with the decision to hasten death than originally. CONCLUSIONS: After nearly 5 years after dialysis discontinuation, families report low levels of distress. A higher frequency of intrusive thoughts was more likely if respondents were spouses or primary caregivers as compared to adult children, siblings, or other relatives. The findings suggest that families successfully adapt to the impact of dialysis withdrawal deaths.

The need for end-of-life care training in nephrology: national survey results of nephrology fellows.

Because of the high mortality rate of end-stage renal disease, nephrologists care for many dying patients. However, the education of nephrology fellows in palliative care has not been assessed. We surveyed second-year nephrology fellows to assess the quantity and quality of teaching they received in palliative medicine and also asked about their preparedness to manage patients at the end of life. A 63% survey response rate yielded 173 surveys for evaluation. Nearly all fellows (99%) agreed that physicians have a responsibility to help patients at the end of life; half thought it was very important to learn how to care for dying patients. On a 10-point scale in which 0 is no teaching and 10 is a lot of teaching, fellows reported significantly less teaching in end-of-life care (mean score, 3.8 +/- 2.6) than in managing a patient with distal renal tubular acidosis (mean score, 6.3 +/- 2.5) or on hemodialysis therapy (mean score, 8.9 +/- 1.5; all P < 0.0001). Specific palliative care content areas were taught infrequently; only 22% of fellows were taught how to tell a patient he or she is dying. Fellows who had contact with a palliative care specialist reported more education on end-of-life issues and believed they were better prepared to provide such care. Fellows' palliative care experiences during fellowship frequently occurred without attending nephrologist supervision; 32% of fellows had conducted 2 or fewer family meetings, and 26% of all family meetings occurred without an attending nephrologist. Fellows believed they were best prepared to manage a patient on hemodialysis therapy (mean score, 8.9 +/- 1) and least prepared to manage a patient at the end of life (mean score, 6.1 +/- 2; P < 0.0001). Our results show that most nephrology fellows believe they should learn how to care for dying patients, but most fellowship programs do not offer this training. Our study therefore suggests that training in palliative care be incorporated into fellowship program curricula.

The Renal Palliative Care Initiative.

Despite ongoing technological advances, patients with end-stage renal disease (ESRD) have a mortality rate of approximately 23% per year, and comorbid cardiovascular, cerebrovascular, and peripheral vascular disorders often make life on dialysis an ordeal. This patient population needs an improved approach to symptom assessment and control, as well as advance care planning and high-quality palliative care. Families need support during the lifetime and after the death of their loved ones. To address these needs, the Renal Palliative Care Initiative (RPCI) was instituted at Baystate Medical Center, a large tertiary care hospital, and at eight dialysis clinics in the Connecticut River Valley. With the cooperation of a large nephrology practice, the Western New England Renal and Transplant Associates, a core group of physicians, nurses, and social workers were trained in palliative medicine, and charged with the goals of developing and implementing innovative interventions. The RPCI's programs include symptom management protocols, advance care planning, and bereavement services for families and staff. The Initiative is increasing completion of formal advance directives by the patient population, while staff and families are particularly pleased with annual renal memorial services. The RPCI experience has much to offer the practice of nephrology, and it is relevant to ongoing efforts to extend palliative medicine beyond the traditional focus on cancer and AIDS.

Symptom burden, quality of life, advance care planning and the potential value of palliative care in severely ill haemodialysis patients.

BACKGROUND: There has been little research on the potential value of palliative care for dialysis patients. In this pilot study, we sought (i) to identify symptom burden, health-related quality of life (HRQoL) and advance directives in extremely ill haemodialysis patients to determine their suitability for palliative care and (ii) to determine the acceptability of palliative care to patients and nephrologists. METHODS: Nineteen haemodialysis patients with modified Charlson co-morbidity scores of > or =8 were recruited. Each completed surveys to assess symptom burden, HRQoL and prior advance care planning. Palliative care specialists then visited patients twice and generated recommendations. Patients again completed the surveys, and dialysis charts were reviewed to assess nephrologists' (i) compliance with recommendations and (ii) documentation of symptoms reported by patients on the symptom assessment survey. Patients and nephrologists then completed surveys assessing their satisfaction with palliative care. RESULTS: Patients reported 10.5 symptoms, 40% of which were noted by nephrologists in patients' charts. HRQoL was significantly impaired. Thirty-two percent of patients had living wills. No differences were observed in symptoms, HRQoL or number of patients establishing advance directives as a result of the intervention. Sixty-eight percent of patients and 76% of nephrologists rated the intervention worthwhile. CONCLUSIONS: Extremely ill dialysis patients have marked symptom burden, considerably impaired HRQoL and frequently lack advance directives, making them appropriate candidates for palliative care. Patients and nephrologists perceive palliative care favourably despite its lack of effect in this study. A more sustained palliative care intervention with a larger sample size should be attempted to determine its effect on the care of this population.

Practical considerations in dialysis withdrawal: "to have that option is a blessing".

Cessation of life-support treatment is an appropriate option for situations in which the burdens of therapy substantially outweigh the benefits. Decisions to withdraw dialysis now precede 1 in 4 deaths of patients who have end-stage renal disease. Guidelines have been recently published to assist clinicians in making these complex and emotionally charged determinations, and they include: relying on shared decision making by all participants, obtaining informed consent, estimating the prognosis on dialysis, adopting a systematic approach for conflict resolution of disagreements, honoring advance directives, and ensuring the provision of palliative care. These principles are discussed in relation to an elderly man with dementia whose family decided to terminate maintenance hemodialysis.

Depression and suicidal ideation in patients who discontinue the life-support treatment of dialysis.

OBJECTIVE: The objective of this study was to determine the prevalence of major depression and suicidal ideation in patients who stop the life-support treatment of dialysis. METHODS: The authors prospectively studied 79 subjects who discontinued maintenance dialysis at eight facilities in North America. Structured interviews were conducted with 23 patients and 76 families. RESULTS: The prevalence of major depression in the sample was between 5% and 25%, and only 1 of 22 patients considered himself to have the illness of depression. Approximately 12% of the respondents were unsure or believed that discontinuing dialysis was the equivalent of suicide. This belief did not correlate with measures of depression. In comparison with the general population there seemed to be an increased prevalence of past suicide attempts. CONCLUSIONS: Most patients who decide to stop dialysis do not seem to be influenced by major depression or ordinary suicidal ideation. Although the sample size was small, these results highlight the need to further examine the theoretical framework and terminology of depression and suicide in the context of terminal illness.

Measuring quality of dying in end-stage renal disease.

Palliative medicine operates under the presumption that it is possible to improve the quality of a patient's death. Nephrology has justifiably taken pride in its reliance on internal benchmarking and the use of quality targets to shape clinical practice innovations, and this article discusses the efforts that are being made to measure end-of-life care of dialysis patients. A tool called the Dialysis Quality of Dying Apgar is described that examines five domains (pain, nonpain symptoms, advance care planning, peacefulness, and time) which are scored and then summed. A recent interdisciplinary workgroup of renal professionals has commissioned a series of focus groups that have attempted to ascertain patient and family values and preferences for the management of terminal situations. The results are summarized, and they should hopefully form a basis for the development of additional research and clinical measurement tools.

The psychiatric landscape of withdrawal.

Withdrawal from dialysis is an appropriate decision for situations in which the burdens of treatment outweigh the benefits. Alternately, it can be viewed as a public health problem and suicide equivalent that contributes to the high mortality of end-stage renal disease (ESRD). More than one in five deaths of patients with ESRD are preceded by dialysis cessation, and approximately 15,000 Americans died last year following a determination to stop this life-support treatment. This article discusses what is known about the psychosocial aspects of the patients who terminate dialysis, the role of depression and other psychiatric disorders, the family perspective, and the relationship of these decisions to suicide.

Update on psychotropic medication use in renal disease.

Renal failure is a common medical condition, and many patients have comorbid psychiatric disorders. In this review, which is intended as a resource for consultation psychiatrists, the authors discuss pharmacokinetic considerations and provide information about the use of individual psychotropic medications in patients with renal disease. Most psychotropic medications are fat soluble, easily pass the blood-brain barrier, are not dialyzable, are metabolized primarily by the liver, and are excreted mainly in bile. Consequently, the majority of these drugs can be safely used with the end-stage renal disease population.
