When Enough Is Enough: The Nephrologist's Responsibility in Ordering Dialysis Treatments

Referral Criteria to Specialist Palliative Care for People with Advanced Chronic Kidney Disease: A Systematic Review

CONTEXT

People with advanced chronic kidney disease (CKD) have significant morbidity, yet for many, access to palliative care occurs late, if at all.

OBJECTIVES

This study sought to examine criteria for referral to specialist palliative care for adults with advanced CKD with a view to improving use of these essential services.

METHODS

Systematic review of studies detailing referral criteria to palliative care in advanced CKD conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guideline and registered (PROSPERO: CRD42021230751).

DATA SOURCES

Electronic databases (Ovid, MEDLINE, Ovid Embase, and PubMed) were used to identify potential studies, which were subjected to double review, data extraction, thematic coding, and descriptive analyses.

RESULTS

Searches yielded 650 unique titles ultimately resulting in 56 studies addressing referral criteria to specialist palliative care in advanced CKD. Of 10 categories of referral criteria, most commonly discussed were: Critical times of treatment decision making (n = 23, 41%); physical or emotional symptoms (n = 22, 39%); limited prognosis (n = 18, 32%); patient age and comorbidities (n = 18, 32%); category of CKD/ biochemical criteria (n = 13, 23%); functional decline (n = 13, 23); psychosocial needs (n = 9, 16%); future care planning (n = 9, 16%); anticipated decline in illness course (n = 8, 14%); and hospital use (n = 8, 14%).

CONCLUSION

Clinicians consider referral to specialist palliative care for a wide range of reasons, with many related to care needs. As palliative care continues to integrate with nephrology, our findings represent a key step towards developing consensus criteria to standardize referral for patients with chronic kidney diseases.

Quality of life in advanced renal disease managed either by haemodialysis or conservative care in older patients

OBJECTIVE

Consideration of quality of life (QoL) in people with end-stage renal disease has become an important part of treatment decision-making. The aim of this study was to report on QoL and other functional outcomes in patients with advanced chronic kidney disease (CKD).

METHOD

This was a cross-sectional study. Two samples of older patients (>60 years old) either conservatively managed (CM) or receiving hospital-based haemodialysis (HD), compared Kidney Disease Quality of Life (KDQoL-36) outcomes.

RESULTS

Data from 263 CM patients (CKD 4 n=188, mean age 73.6 years, 48 women; CKD 5 n=75, mean age 74.4 years, 26 women) and 74 patients on HD (mean age 73.8 years, 24 women) were analysed. Significant group differences were identified for two subscales of KDQoL-36. Symptoms/Problems List subscale was significantly better for those receiving HD compared with those CM with CKD 5 (p=<0.001). Symptom/Problem List scores of CM CKD stage 4 patients were not significantly different compared with HD patients but were significantly better than CM CKD stage 5 patients (p<0.001). Burden of Kidney Disease subscale was significantly better for both CKD 4 (p<0.001) and CKD 5 (p<0.001) CM patients when compared with those receiving HD.

CONCLUSION

Symptoms of advanced CKD significantly impact QoL for patients CM with CKD stage 5. Conversely, QoL is significantly impacted for those in receipt of HD due to the burden of treatment. These findings provide evidence for the use of QoL tools to help with clinical prognostication in advanced CKD. Using QoL tools will ensure specialist support is available for appropriate management of patients with CKD.

Parameters affecting prognosis after hemodialysis withdrawal: experience from a single center

INTRODUCTION

Withdrawal from maintenance hemodialysis is unavoidable in some patients due to their poor general condition; however, their survival days vary depending on their health status. The factors associated with life prognosis in the terminal phase in patients undergoing hemodialysis remain unclear.

METHODS

Patients who died after withdrawal from hemodialysis between 2011 and 2021 at Nagasaki Renal Center were included. Patient background data were collected, and the association between the patients' clinical features and survival duration was analyzed.

RESULTS

The withdrawal group included 174 patients (79.8 ± 10.8 years old; 50.6% male; median dialysis vintage, 3.6 years). The most common reason for withdrawal (95%) was that hemodialysis was more harmful than beneficial because of the patient's poor general condition. The median time from withdrawal to death was 4 days (interquartile range, 3-10 days). Multivariable Cox proportional regression analysis showed that oral nutrition (hazard ratio (HR), 1.98; 95% confidence interval (CI), 1.12-3.50; P = 0.03), hypoxemia (HR, 2.32; 95% CI, 1.55-3.47; P < 0.01), ventilator use (HR, 0.26; 95% CI, 0.11-0.58; P < 0.01), and pleural effusion (HR, 1.54; CI, 1.01-2.37; P = 0.04) were associated with increased survival duration. In contrast, antibiotics and vasopressor administration were not associated with the survival duration.

CONCLUSION

In this study, we explored the parameters affecting the survival of patients who withdrew from hemodialysis. Physicians could use our results to establish more accurate predictions, which may help the patient and their family to emotionally accept and implement the desired care plan.

Asking the right questions: towards a person-centered conception of shared decision-making regarding treatment of advanced chronic kidney disease in older patients

An increasing number of older patients have to decide on a treatment plan for advanced chronic kidney disease (CKD), involving dialysis or conservative care. Shared decision-making (SDM) is recommended as the model for decision-making in such preference-sensitive decisions. The aim of SDM is to come to decisions that are consistent with the patient’s values and preferences and made by the patient and healthcare professional working together. In clinical practice, however, SDM appears to be not yet routine and needs further implementation. A shift from a biomedical to a person-centered conception might help to make the process more shared. Shared should, therefore, be interpreted as two persons bringing two perspectives to the table, that both need to be explored during the decision-making process. Starting from the patient’s perspective will enable to determine the mutual goals of care first and, subsequently, determine the best way for achieving those goals. To perform such SDM, the healthcare professional needs to become a skilled companion, being part of the patient’s relational context, and start asking the right questions about what matters to the patient as person. In this article, we describe the need for a person-centered conception of SDM for the setting of older patients with advanced CKD.

Choices in hemodialysis therapies: variants, personalized therapy and application of evidence-based medicine

The extent of removal of the uremic toxins in hemodialysis (HD) therapies depends primarily on the dialysis membrane characteristics and the solute transport mechanisms involved. While designation of ‘flux’ of membranes as well toxicity of compounds that need to be targeted for removal remain unresolved issues, the relative role, efficiency and utilization of solute removal principles to optimize HD treatment are better delineated. Through the combination and intensity of diffusive and convective removal forces, levels of concentrations of a broad spectrum of uremic toxins can be lowered significantly and successfully. Extended clinical experience as well as data from several clinical trials attest to the benefits of convection-based HD treatment modalities. However, the mode of delivery of HD can further enhance the effectiveness of therapies. Other than treatment time, frequency and location that offer clinical benefits and increase patient well-being, treatment- and patient-specific criteria may be tailored for the therapy delivered: electrolytic composition, dialysate buffer and concentration and choice of anticoagulating agent are crucial for dialysis tolerance and efficacy. Evidence-based medicine (EBM) relies on three tenets, i.e. clinical expertise (i.e. doctor), patient-centered values (i.e. patient) and relevant scientific evidence (i.e. science), that have deviated from their initial aim and summarized to scientific evidence, leading to tyranny of randomized controlled trials. One must recognize that practice patterns as shown by Dialysis Outcomes and Practice Patterns Study and personalization of HD care are the main driving force for improving outcomes. Based on a combination of the three pillars of EBM, and particularly on bedside patient–clinician interaction, we summarize what we have learned over the last 6 decades in terms of best practices to improve outcomes in HD patients. Management of initiation of dialysis, vascular access, preservation of kidney function, selection of biocompatible dialysers and use of dialysis fluids of high microbiological purity to restrict inflammation are just some of the approaches where clinical experience is vital in the absence of definitive scientific evidence. Further, HD adequacy needs to be considered as a broad and multitarget approach covering not just the dose of dialysis provided, but meeting individual patient needs (e.g. fluid volume, acid–base, blood pressure, bone disease metabolism control) through regular assessment—and adjustment—of a series of indicators of treatment efficiency. Finally, in whichever way new technologies (i.e. artificial intelligence, connected health) are embraced in the future to improve the delivery of dialysis, the human dimension of the patient–doctor interaction is irreplaceable. Kidney medicine should remain ‘an art’ and will never be just ‘a science’.

Potentially Inappropriate Treatments at the End of Life in Nursing Home Residents: Findings From the PACE Cross-Sectional Study in Six European Countries

CONTEXT

Certain treatments are potentially inappropriate when administered to nursing homes residents at the end of life and should be carefully considered. An international comparison of potentially inappropriate treatments allows insight into common issues and country-specific challenges of end-of-life care in nursing homes and helps direct health-care policy in this area.

OBJECTIVES

To estimate the prevalence of potentially inappropriate treatments in the last week of life in nursing home residents and analyze the differences in prevalence between countries.

METHODS

A cross-sectional study of deceased residents in nursing homes (2015) in six European countries: Belgium (Flanders), England, Finland, Italy, The Netherlands, and Poland. Potentially inappropriate treatments included enteral administration of nutrition, parental administration of nutrition, artificial fluids, resuscitation, artificial ventilation, blood transfusion, chemotherapy/radiotherapy, dialysis, surgery, antibiotics, statins, antidiabetics, new oral anticoagulants. Nurses were questioned about whether these treatments were administered in the last week of life.

RESULTS

We included 1384 deceased residents from 322 nursing homes. In most countries, potentially inappropriate treatments were rarely used, with a maximum of 18.3% of residents receiving at least one treatment in Poland. Exceptions were antibiotics in all countries (between 11.3% in Belgium and 45% in Poland), artificial nutrition and hydration in Poland (54.3%) and Italy (41%) and antidiabetics in Poland (19.7%).

CONCLUSION

Although the prevalence of potentially inappropriate treatments in the last week of life was generally low, antibiotics were frequently prescribed in all countries. In Poland and Italy, the prevalence of artificial administration of food/fluids in the last week of life was high, possibly reflecting country differences in legislation, care organization and culture, and the palliative care competences of staff.

Barriers to Conservative Management Conversations: Perceptions of Nephrologists and Fellows-in-Training

Background: Not all treatments are appropriate for all individuals with kidney failure (KF). Studies suggest that conversations surrounding end-of-life decisions occur too late or not at all. Objectives: The aim of this research was to identify perceived barriers to such discussions among nephrologists and nephrology fellows to determine if barriers differ by experience level. Design: Phase I consisted of semistructured telephone interviews with nephrologists and fellows. Phase II included focus groups with nominal group technique in which providers ranked barriers to discussions about not initiating/withholding dialysis (NIWD) or discontinuing dialysis (DD). Setting/Subjects: U.S. community-based nephrologists and nephrology fellows. Results: Seven interviews were conducted with each group (n = 14) in phase I. Many barriers cited were similar among providers, however, differences were related to fellows' position as trainees citing the "reaction of their attending/supervising physician or other providers" as a barrier to NIWD and "lacking their attending physician's support" as a barrier to DD. Six focus groups were conducted, nephrologists (n = 22) and fellows (n = 18), in phase II. The highest ranked barrier to NIWD for nephrologists was "discordant opinions among patient and family"; fellows ranked "time to hold conversation" highest. Nephrologists' highest barrier to DD was the "finality of the decision (death)"; fellows ranked the "inertia of the clinical encounter" highest. Conclusions: Capturing the perspectives of nephrologists and fellows concerning the barriers to conservative management of patients with KF may inform the development of targeted education/training interventions by experience level focused on communication skills, conflict resolution, and negotiation.

'Supportive and Palliative Care Indicators Tool (SPICT) improves renal nurses' confidence in recognising patients approaching end of life'

BACKGROUND

Identification of people with deteriorating health is essential for quality patient-centred care and optimal management. The Supportive and Palliative Care Indicators Tool (SPICT) is a guide to identifying people with deteriorating health for care planning without incorporating a prognostic time frame.

OBJECTIVES

To improve renal nursing staff confidence in identifying patients approaching end-of-life and advocate for appropriate multidisciplinary care planning.

DESIGN

This pilot feasibility prospective cohort study conducted in the renal ward of a major metropolitan health service during 2019 included a preintervention/postintervention survey questionnaire. A programme of education was implemented training staff to recognise end-of-life and facilitate appropriate care planning.

RESULTS

Several domains in the postintervention survey demonstrated a statistically significant improvement in renal nurses' perception of confidence in their ability to recognise end of life. Of the 210 patients admitted during the study period, 16% were recognised as SPICT positive triggering renal physicians to initiate discussions about end-of-life care planning with patients and their families and to document a plan. Six months poststudy, 72% of those patients recognised as SPICT positive had died with a documented plan of care in place.

CONCLUSION

The use of SPICT for hospital admissions and the application of education in topics related to end-of-life care resulted in a significant improvement in nurses' confidence in recognising deteriorating and frail patients approaching their end of life. The use of this tool also increased the number of deteriorating patients approaching end of life with goals of care documented.

Ethical challenges in nephrology: a call for action

The American Society of Nephrology, the European Renal Association-European Dialysis and Transplant Association and the International Society of Nephrology Joint Working Group on Ethical Issues in Nephrology have identified ten broad areas of ethical concern as priority challenges that require collaborative action. Here, we describe these challenges - equity in access to kidney failure care, avoiding futile dialysis, reducing dialysis costs, shared decision-making in kidney failure care, living donor risk evaluation and decision-making, priority setting in kidney disease prevention and care, the ethical implications of genetic kidney diseases, responsible advocacy for kidney health and management of conflicts of interest - with the aim of highlighting the need for ethical analysis of specific issues, as well as for the development of tools and training to support clinicians who treat patients with kidney disease in practising ethically and contributing to ethical policy-making.

Health-related quality of life and symptoms of conservative care versus dialysis in patients with end-stage kidney disease: a systematic review

Background

Non-dialytic conservative care (CC) has been proposed as a viable alternative to maintenance dialysis for selected older patients to treat end-stage kidney disease (ESKD). This systematic review compares both treatment pathways on health-related quality of life (HRQoL) and symptoms, which are major outcomes for patients and clinicians when deciding on preferred treatment.

Methods

We searched PubMed, Embase, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL) Plus and PsycINFO from inception to 1 October 2019 for studies comparing patient-reported HRQoL outcomes or symptoms between patients who chose either CC or dialysis for ESKD.

Results

Eleven observational cohort studies were identified comprising 1718 patients overall. There were no randomized controlled trials. Studies were susceptible to selection bias and confounding. In most studies, patients who chose CC were older and had more comorbidities and worse functional status than patients who chose dialysis. Results were broadly consistent across studies, despite considerable clinical and methodological heterogeneity. Patient-reported physical health outcomes and symptoms appeared to be worse in patients who chose CC compared with patients who chose dialysis but had not yet started, but similar compared with patients on dialysis. Mental health outcomes were similar between patients who chose CC or dialysis, including before and after dialysis start. In patients who chose dialysis, the burden of kidney disease and impact on daily life increased after dialysis start.

Conclusions

The available data, while heterogeneous, suggest that in selected older patients, CC has the potential to achieve similar HRQoL and symptoms compared with a dialysis pathway. High-quality prospective studies are needed to confirm these provisional findings.

Changing epidemiology and outcomes of acute kidney injury in Brazilian patients: a retrospective study from a teaching hospital

PURPOSE

While considerable information is available on acute kidney injury (AKI) in North America and Europe, large comprehensive epidemiologic studies on AKI from Latin America and Asia are still lacking. The present study aimed to evaluate the epidemiology and outcomes of AKI in patients evaluated by nephrologists in a Brazilian teaching hospital.

METHODS

We performed a large retrospective observational study that looked into the epidemiology of AKI and its effect on patient outcomes across time periods. For comparison purposes, patients were divided into two groups according to the year of follow up: 2011-2014 and 2015-2018.

RESULTS

We enrolled 7976 AKI patients and, after excluding patients with chronic kidney disease stages 4 and 5, kidney transplant recipients and those with incomplete data, 5428 AKI patients were included (68%). The maximum AKI stage was 3 (50.6%), and there was a mortality rate of 34.3% (1865 patients). Dialysis treatment was indicated in 928 patients (17.1%). Patient survival improved along the study periods, and patients treated in 2015-2018 had a relative risk death reduction of 0.89 (95% CI 0.81-0.98, p = 0.02). The independent risk factors for mortality were sepsis, > 65 years of age, admission to the intensive care unit, AKI-KDIGO 3, recurrent AKI, no metabolic and fluid demand to capacity imbalance (as a dialysis indication), and the period of treatment.

CONCLUSION

We observed an improvement in AKI patient survival over the years, even after correction for several confounders and using a competing risk approach. Identification of risk factors for mortality can help in decision-making for timely intervention, leading to better clinical outcomes.

Management dilemmas in pediatric nephrology: time-limited trials of dialysis therapy

BACKGROUND

Time-limited trials of dialysis have been proposed as a third option in addition to initiation of treatment and comfort-care only in the setting of high uncertainty or discordance between the treating team and child/family or among the treating team.

CASE-DIAGNOSIS/TREATMENT

The index case was noted antenatally to have severe kidney disease and pulmonary hypoplasia. In light of the guarded, but uncertain prognosis and a lack of consensus among the treating team, as well as between the treating team and the family, a time-limited trial of dialysis was initiated. Six days later the child developed bacteremia due to infection of the dialysis catheter. The treating team felt this was a failure of the trial and that future dialysis should be withheld, the family disagreed.

CONCLUSION

A time-limited trial is a problematic option. Providers may be better suited by returning to the dichotomous choice of withholding or initiating treatment.

KEY MANAGEMENT POINTS

• Time-limited trials offer potential benefits in terms of alleviating the burden of decision-making in the setting of uncertainty, offering an opportunity to forecast a poor prognosis, help avoid interprofessional conflict, and providing support for patients, their families, and staff. • Time-limited trials have important limitations, including the use of time limits, difficulty in determining clear, meaningful endpoints, and different interpretations of a trial of therapy between parents and providers. • Decisions regarding the initiation, withholding, and withdrawal of dialysis should be made based on regular assessments of the benefits and burdens of the intervention for the child. • Pediatric nephrologists are better served to abandon the concept of time-limited trials.

[Ethical issues perceived by health care professionals working in chronic hemodialysis centers]

BACKGROUND

Clinical teams working at chronic hemodialysis centers (CHC) frequently have to face ethical problems, but there is no systematic approach to deal with them.

AIM

To study the ethical problems perceived by health professionals at CHC.

MATERIAL AND METHODS

Eighty randomly selected physicians and 139 nurses from 23 CHC, answered a structured questionnaire, devised by the research team.

RESULTS

Twenty-six percent of respondents had postgraduate studies in clinical ethics. The ethical problems mentioned by respondents were therapeutic disproportion in 66.7%, lack of communication between patients, their families and the clinical team in 25.9%, personal conflicts of interests related with hemodialysis prescription in 14.6% and conflicts of interests of other members of the clinical team in 30.6%. The percentage of respondents that experienced not starting or discontinuing hemodialysis treatment due to decision of patients’ relatives was 86.8%. Only 45.2% of health professionals had the opportunity to take part in decision-making meetings. Eighty seven percent of respondents supported the use of advanced directives in the event of a cardio respiratory arrest during treatment.

CONCLUSIONS

To improve the approach to ethical problems in CHC, it is necessary to improve training in clinical ethics, promote an effective dialogue between the patients, their families and health professionals, and follow their advance directives in case of cardiac arrest during treatment.

Advance care planning: a qualitative study of dialysis patients and families

BACKGROUND AND OBJECTIVES

More than 90,000 patients with ESRD die annually in the United States, yet advance care planning (ACP) is underutilized. Understanding patients' and families' diverse needs can strengthen systematic efforts to improve ACP.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

In-depth interviews were conducted with a purposive sample of patients and family/friends from dialysis units at two study sites. Applying grounded theory, interviews were audiotaped, professionally transcribed, and analyzed in an iterative process. Emergent themes were identified, discussed, and organized into major themes and subthemes.

RESULTS

Thirteen patients and nine family/friends participated in interviews. The mean patient age was 63 years (SD 14) and five patients were women. Participants identified as black (n=1), Hispanic (n=4), Native American (n=4), Pacific Islander (n=1), white (n=11), and mixed (n=1). Three major themes with associated subthemes were identified. The first theme, "Prior experiences with ACP," revealed that these discussions rarely occur, yet most patients desire them. A potential role for the primary care physician was broached. The second theme, "Factors that may affect perspectives on ACP," included a desire for more of a connection with the nephrologist, positive and negative experiences with the dialysis team, disenfranchisement, life experiences, personality traits, patient-family/friend relationships, and power differentials. The third theme, "Recommendations for discussing ACP," included thoughts on who should lead discussions, where and when discussions should take place, what should be discussed and how.

CONCLUSIONS

Many participants desired better communication with their nephrologist and/or their dialysis team. A number expressed feelings of disenfranchisement that could negatively impact ACP discussions through diminished trust. Life experiences, personality traits, and relationships with family and friends may affect patient perspectives regarding ACP. This study's findings may inform clinical practice and will be useful in designing prospective intervention studies to improve patient and family experiences at the end of life.

Patient-centered care: an opportunity to accomplish the "Three Aims" of the National Quality Strategy in the Medicare ESRD program

In light of mounting federal government debt and levels of Medicare spending that are widely viewed as unsustainable, commentators have called for a transformation of the United States health care system to deliver better care at lower costs. This article presents the priorities of the Coalition for Supportive Care of Kidney Patients for how clinicians might achieve this transformation for patients with advanced CKD and their families. The authors suspect that much of the high-intensity, high-cost care currently delivered to patients with advanced kidney disease may be unwanted and that the "Three Aims" put forth by the National Quality Strategy of better care for the individual, better health for populations, and reduced health care costs may be within reach for patients with CKD and ESRD. This work describes the coalition's vision for a more patient-centered approach to the care of patients with kidney disease and argues for more concerted efforts to align their treatments with their goals, values, and preferences. Key priorities to achieve this vision include using improved prognostic models and decision science to help patients, their families, and their providers better understand what to expect in the future; engaging patients and their families in shared decision-making before the initiation of dialysis and during the course of dialysis treatment; and tailoring treatment strategies throughout the continuum of their care to address what matters most to individual patients.

Ethical challenges with hemodialysis patients who lack decision-making capacity: behavioral issues, surrogate decision-makers, and end-of-life situations

Hemodialysis (HD) is routinely offered to patients with end-stage renal disease in the United States who are ineligible for other renal replacement modalities. The frequency of HD among the US population is greater than all other countries, except Taiwan and Japan. In US, patients are often dialyzed irrespective of age, comorbidities, prognosis, or decision-making capacity. Determination of when patients can no longer dialyze is variable and can be dialysis-center specific. Determinants may be related to progressive comorbidities and frailty, mobility or access issues, patient self-determination, or an inability to tolerate the treatment safely for any number of reasons (e.g., hypotension, behavioral issues). Behavioral issues may impact the safety of not only patients themselves, but also those around them. In this article the authors present the case of an elderly patient on HD with progressive cognitive impairment and combative behavior placing him and others at risk of physical harm. The authors discuss the medical, ethical, legal, and psychosocial challenges to care of such patients who lack decision-making capacity with a focus on variable approaches by regions and culture. This manuscript provides recommendations and highlights resources to assist nephrologists, dialysis personnel, ethics consultants, and palliative medicine teams in managing such patients to resolve conflict.

Aging and chronic kidney disease

A recent report has dealt with geriatric nephrology, including epidemiology and pathophysiology of chronic kidney disease (CKD), attempting to get nephrologists to pay more attention to elderly CKD patients. The aims of this article are to summarize the morphological and functional properties of the aging kidney, and to better understand nephrology care for elderly CKD patients. The kidneys are affected by the aging process, which results in numerous effects on the renal system. In addition, the elderly population is hetereogenous - some have a decline in GFR explained by diseases that complicate aging such as arteriosclerosis with hypertension, whereas in the most of healthy adults the decline in GFR is much more modest and not inevitable. The values for normal estimated glomerular filtration rate (eGFR) in aging population have important implications for the diagnosis of CKD in the elderly. However, the MDRD equation underestimates mean eGFR by 25% and the CKD-EPI equation underestimates mean GFR by 16%. This bias may lead to misclassifying healthy older persons as having CKD. It is also still unknown whether and how age influences the predictive role of other risk factors for end-stage renal disease (ESRD) and death in referred as well as unreferred patients. The risk of ESRD was reported to be higher than the risk of death without ESRD for ages <60 years, and independent of eGFR. Proteinuria significantly increased the risk of ESRD with advancing age. In older patients on nephrology care, the risk of ESRD prevailed over mortality even when eGFR was not severely impaired. Proteinuria increases the risk of ESRD, while the predictive role of other modifiable risk factors was unchanged compared with younger patients. The decision to initiate renal replacement therapy in the elderly is complicated by more challenges than in younger patients. Calorie restriction and Klotho deficiency may be a candidate therapeutic target for attenuating kidney aging. © 2014 S. Karger AG, Basel.

Withdrawal from Dialysis and Palliative Care for Severely Ill Dialysis Patients in terms of Patient-Centered Medicine

We treated a dementia patient with end stage chronic kidney disease (CKD). The patient also had severe chronic heart disease and suffered from untreatable respiratory distress during the clinical course of his illness. We therefore initiated peritoneal dialysis therapy (PD) as renal replacement therapy, although we had difficulties continuing stable PD for many reasons, including a burden on caregivers and complications associated with PD therapy itself. Under these circumstances we considered that palliative care prior to intensive care may have been an optional treatment. This was a distressing decision regarding end-of-life care for this patient. We were unable to confirm the patient's preference for end-of-life care due to his dementia. Following sufficiently informed consent the patient's family accepted withdrawal from dialysis (WD). We simultaneously initiated nonabandonment and continuation of careful follow-up including palliative care. We concluded that the end-of-life care we provided would contribute to a peaceful and dignified death of the patient. Although intensive care based on assessment of disease is important, there is a limitation to care, and therefore we consider that WD and palliative care are acceptable options for care of our patients in the terminal phase of their lives.

Should an elderly patient with stage V CKD and dementia be started on dialysis?

The burden of cognitive impairment appears to increase with progressive renal disease, such that the prevalence of dementia among those starting dialysis, or those already established on dialysis, is high. The appropriateness of dialysis initiation in this population has been questioned, and current Renal Physician Association guidelines suggest forgoing dialysis in individuals who have dementia and lack awareness of self and environment. Patients are, however, also entitled to equal rights and respect, equal access to health care services, and an opportunity to engage in shared decision-making processes, particularly if there is concern over reversibility of disease. This article discusses, on the basis of principles of beneficence and nonmaleficence, the arguments in favor of and against dialysis use, and the process of determining an appropriate care plan. Factors discussed include the current societal trend toward a technological imperative, premature fatalism, survival benefits, and the implications of providing care to patients who are unable to express their tolerance for symptoms associated with the treatment or lack of treatment.

Survival after dialysis discontinuation and hospice enrollment for ESRD

BACKGROUND AND OBJECTIVES

Textbooks report that patients with ESRD survive for 7-10 days after discontinuation of dialysis. Studies describing actual survival are limited, however, and research has not defined patient characteristics that may be associated with longer or shorter survival times. The goals of this study were to determine the mean life expectancy of patients admitted to hospice after discontinuation of dialysis, and to identify independent predictors of survival time.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Data for demographics, clinical characteristics, and survival were obtained from 10 hospices for patients with ESRD who discontinued dialysis before hospice admission. Data were collected for patients admitted between January 1, 2008 and May 15, 2012. All hospices were members of the Coalition of Hospices Organized to Investigate Comparative Effectiveness network, which obtains de-identified data from an electronic medical record.

RESULTS

Of 1947 patients who discontinued dialysis, the mean survival after hospice enrollment was 7.4 days (range, 0-40 days). Patients who discontinued dialysis had significantly shorter survival compared with other patients (n=124,673) with nonrenal hospice diagnoses (mean survival 54.4 days; hazard ratio, 2.96; 95% confidence interval, 2.82 to 3.09; P<0.001). A Cox proportional hazards model identified seven independent predictors of earlier mortality after dialysis discontinuation, including male sex, referral from a hospital, lower functional status (Palliative Performance Scale score), and the presence of peripheral edema.

CONCLUSIONS

Patients who discontinue dialysis have significantly shorter survival than other hospice patients. Individual survival time varies greatly, but several variables can be used to predict survival and tailor a patient's care plan based on estimated prognosis.

Beyond the futility argument: the fair process approach and time-limited trials for managing dialysis conflict

Futility is an ancient concept arising from Greek mythology that was resurrected for its medical application in the 1980s with the proliferation of many lifesaving technologies, including dialysis and renal transplantation. By that time, the domineering medical paternalism that characterized the pre-1960s physician-patient relationship morphed into assertive patient autonomy, and some patients began to claim the right to demand aggressive, high-technology interventions, despite physician disapproval. To counter this power struggle, the establishment of a precise definition of futility offered hope for a futility policy that would allow physicians to justify withholding or withdrawing treatment, despite patient and family objections. This article reviews the various attempts made to define medical futility and describes their limited applicability to dialysis. When futility concerns arise, physicians should recognize the opportunity to address conflict, using best practice communication skills. Physicians would also benefit from understanding the ethical principles of respect for patient autonomy, beneficence, nonmaleficence, justice, and professional integrity that underlie medical decision-making. Also reviewed is the use of a fair process approach or time-limited trial when conflict resolution cannot be achieved. These topics are addressed in the Renal Physician Association's clinical practice guideline Shared Decision-Making in the Appropriate Initiation and Withdrawal from Dialysis, with which nephrologists should be well versed. A case presentation of intractable calciphylaxis in a new dialysis patient illustrates the pitfalls of physicians not fully appreciating the ethics of medical decision-making and failing to use effective conflict management approaches in the clinical practice guideline.

Decision-making in the face of end-stage organ failure: high-risk transplantation and end-of-life care

PURPOSE OF REVIEW

Pediatric solid organ transplantation numbers have been increasing over the years. Research and the medical literature tends to focus on advancing the field and innovation - which often leads to higher risk and more complex procedures. How do we decide when it is too much - too much risk; too much uncertainty? Who makes that decision? Literature is scarce and usually focuses on end-of-life decision-making. This article does not purport to have the answers, but will highlight the depth and breadth of points that must be taken into consideration.

RECENT FINDINGS

There are many factors that contribute to the decision-making in the context of high-risk solid organ transplantation in children. Focus needs to include quality of life in the pediatric context, in addition to survival. End-of-life discussions should be included early in the process. Societal factors must be considered in an era of donor organ shortages. Shared decision-making should be the approach.

SUMMARY

The key guiding principle is to make a decision about what is best for a child requiring a high-risk transplant based not only on survival, but also on an acceptable quality of life on the background of optimal utilization of a scarce societal resource.

Communication skills training for dialysis decision-making and end-of-life care in nephrology

Nephrology fellows often face difficult conversations about dialysis initiation or withdrawal but are frequently unprepared for these discussions. Despite evidence that communication skills are teachable, few fellowship programs include such training. A communication skills workshop for nephrology fellows (NephroTalk) focused on delivering bad news and helping patients define care goals, including end-of-life preferences. This 4-hour workshop, held in October and November 2011, included didactics and practice sessions with standardized patients. Participants were nephrology fellows at Duke University and the University of Pittsburgh (n=22). Pre- and post-workshop surveys evaluated efficacy of the curriculum and measured changes in perceived preparedness on the basis on workshop training. Overall, 14% of fellows were white and 50% were male. Less than one-third (6 of 22) reported prior palliative care training. Survey response rate varied between 86% and 100%. Only 36% (8 of 22) and 38% (8 of 21) of respondents had received structured training in discussions for dialysis initiation or withdrawal. Respondents (19 of 19) felt that communication skills were important to being a "great nephrologist." Mean level of preparedness as measured with a five-point Likert scale significantly increased for all skills (range, 0.5-1.14; P<0.01), including delivering bad news, expressing empathy, and discussing dialysis initiation and withdrawal. All respondents (21 of 21) reported they would recommend this training to other fellows. NephroTalk is successful for improving preparedness among nephrology fellows for having difficult conversations about dialysis decision-making and end-of-life care.

The ethics of end-of-life care for patients with ESRD

Patients with ESRD have extensive and unique palliative care needs, often for years before death. The vast majority of patients, however, dies in acute care facilities without accessing palliative care services. High mortality rates along with a substantial burden of physical, psychosocial, and spiritual symptoms and an increasing prevalence of decisions to withhold and stop dialysis all highlight the importance of integrating palliative care into the comprehensive management of ESRD patients. The focus of renal care would then extend to controlling symptoms, communicating prognosis, establishing goals of care, and determining end-of-life care preferences. Regretfully, training in palliative care for nephrology trainees is inadequate. This article will provide a conceptual framework for renal palliative care and describe opportunities for enhancing palliative care for ESRD patients, including improved chronic pain management and advance care planning and a new model for delivering high-quality palliative care that includes appropriate consultation with specialist palliative care.

Critical and honest conversations: the evidence behind the "Choosing Wisely" campaign recommendations by the American Society of Nephrology

Estimates suggest that one third of United States health care spending results from overuse or misuse of tests, procedures, and therapies. The American Board of Internal Medicine Foundation, in partnership with Consumer Reports, initiated the "Choosing Wisely" campaign to identify areas in patient care and resource use most open to improvement. Nine subspecialty organizations joined the campaign; each organization identified five tests, procedures, or therapies that are overused, are misused, or could potentially lead to harm or unnecessary health care spending. Each of the American Society of Nephrology's (ASN's) 10 advisory groups submitted recommendations for inclusion. The ASN Quality and Patient Safety Task Force selected five recommendations based on relevance and importance to individuals with kidney disease.Recommendations selected were: (1) Do not perform routine cancer screening for dialysis patients with limited life expectancies without signs or symptoms; (2) do not administer erythropoiesis-stimulating agents to CKD patients with hemoglobin levels ≥10 g/dl without symptoms of anemia; (3) avoid nonsteroidal anti-inflammatory drugs in individuals with hypertension, heart failure, or CKD of all causes, including diabetes; (4) do not place peripherally inserted central catheters in stage 3-5 CKD patients without consulting nephrology; (5) do not initiate chronic dialysis without ensuring a shared decision-making process between patients, their families, and their physicians.These five recommendations and supporting evidence give providers information to facilitate prudent care decisions and empower patients to actively participate in critical, honest conversations about their care, potentially reducing unnecessary health care spending and preventing harm.

Renal replacement therapy in the elderly population

ESRD has become an important problem for elderly patients. The segment of the ESRD population age 65 years or older has grown considerably, and this growth is expected to accelerate in coming years. Nephrologists caring for the elderly with advanced kidney disease will encounter patients with comorbid conditions common in younger patients, as well as physical, psychological, and social challenges that occur with increased frequency in the aging population. These challenging factors must be addressed to help inform decisions regarding the option to initiate dialysis, the choice of dialysis modality, whether to pursue kidney transplantation, and end-of-life care. This article will highlight some common problems encountered by elderly patients with ESRD and review data on the clinical outcomes of elderly patients treated with different modalities of dialysis, outcomes of kidney transplantation in the elderly, and nondialytic management of CKD stage 5.

Conservative management of end-stage renal disease without dialysis: a systematic review

PURPOSE

To summarize evidence on conservative, nondialytic management of end-stage renal disease regarding 1) prognosis and 2) symptom burden and quality of life (QOL).

METHODS

Medline, Cinahl, and Cochrane were searched for records indexed prior to March 1, 2011. Bibliographies of articles and abstracts from recent meetings were reviewed. Authors and nephrologists were contacted to identify additional studies. Articles were reviewed by two authors and selected if they described stage 5 chronic kidney disease (CKD) patients managed without dialysis, including one or more of the following outcomes: prognosis, symptoms, or QOL. Levels of evidence ratings were assigned using the SORT (Strength of Recommendation Taxonomy) system. Data was abstracted independently by two authors for descriptive analysis.

RESULTS

Thirteen studies were included. In studies of prognosis, conservative management resulted in median survival of at least six months (range 6.3 to 23.4 months). Findings are mixed as to whether dialysis prolongs survival in the elderly versus conservative, nondialytic management. Any survival benefit from dialysis decreases with comorbidities, especially ischemic heart disease. Patients managed conservatively report a high symptom burden, underscoring the need for concurrent palliative care. Additional head-to-head studies are needed to compare the symptoms of age-matched dialysis patients, but preliminary studies suggest that QOL is similar.

CONCLUSIONS

Conservative management is an important alternative to discuss when counseling patients and families about dialysis. Unlike withdrawal of dialysis in which imminent death is expected, patients who decline dialysis initiation can live for months to years with appropriate supportive care.

Discussions of the kidney disease trajectory by elderly patients and nephrologists: a qualitative study

BACKGROUND

Elderly patients with advanced kidney disease experience considerable disability, morbidity, and mortality. Little is known about the impact of physician-patient interactions on patient preparation for the illness trajectory. We sought to describe how nephrologists and older patients discuss and understand the prognosis and course of kidney disease leading to renal replacement therapy.

METHODS

We conducted focus groups and interviews with 11 nephrologists and 29 patients older than 65 years with advanced chronic kidney disease or receiving hemodialysis. Interviews were audiorecorded and transcribed. We used qualitative analytic methods to identify common and recurrent themes related to the primary research question.

RESULTS

We identified 6 themes that describe how the kidney disease trajectory is discussed and understood: (1) patients are shocked by their diagnosis, (2) patients are uncertain how their disease will progress, (3) patients lack preparation for living with dialysis, (4) nephrologists struggle to explain illness complexity, (5) nephrologists manage a disease over which they have little control, and (6) nephrologists tend to avoid discussions of the future. Patients and nephrologists acknowledged that prognosis discussions are rare. Patients tended to cope with thoughts of the future through avoidance by focusing on their present clinical status. Nephrologists reported uncertainty and concern for evoking negative reactions as barriers to these conversations.

CONCLUSIONS

Patients and nephrologists face challenges in understanding and preparing for the kidney disease trajectory. Communication interventions that acknowledge the role of patient emotion and address uncertainty may improve how nephrologists discuss disease trajectory with patients and thereby enhance their understanding and preparation for the future.

The "no dialysis" option

Increasing numbers of patients are starting dialysis who have limited prognoses for 6-month survival. The presence of multiple comorbidities, aging, and frailty contributes to this phenomenon. The rate of dialysis withdrawal has been accelerating over the past decade, and this calls into question the condition of patients who are initiating dialysis. One option is to consider and discuss the "no dialysis" option with patients and family. Patients need to be identified who may benefit from this option, and their medical management needs to be reviewed.
