Withholding and Withdrawal from Dialysis: What We Know About How Our Patients Die

Kidney Clinicians' Perceptions of Challenges and Aspirations to Improve End-Of-Life Care Provision

Introduction

End-of-life care is an essential part of integrated kidney care. However, renal clinicians' experiences of care provision and perceptions of end-of-life care needs are limited. This study explored renal clinicians' experiences of providing end-of-life care and developed recommendations to improve experiences.

Methods

An exploratory qualitative study using semistructured focus groups and 1 interview was undertaken at 5 kidney services in Victoria, Australia. The transcripts were analyzed thematically.

Results

Between February and December 2017, 54 renal clinicians (21 doctors and 33 nurses) participated in the study. Clinicians reported multiple challenges of end-of-life care experiences resulting in compromised treatment planning and decision making and highlighted priorities to guide better care experiences. Challenges of providing end-of-life care were underpinned by mismatches in illness and treatment expectations, limited engagement in advance care planning, medical complexity, and differences between clinicians and patients in what constituted quality of life. These challenges were associated with compromised end-of-life care planning, which resulted in care experiences that were rushed with a prolonged treatment focus, risking limited preparation for death and moral distress. Clinicians aspired for positive end-of-life care experiences, including patient control and consensus in decision making, and a coordinated and collaborative approach across healthcare providers.

Conclusions

Renal clinicians highlighted multiple factors and circumstances which resulted in experiences of compromised end-of-life care for patients with kidney disease. To improve care experiences, clinician-directed priorities included more training and support to facilitate systematic and earlier discussions about illness expectations and end-of-life care planning and greater communication and collaboration across healthcare providers is required.

Factors Associated With Withdrawal From Dialysis Therapy in Incident Hemodialysis Patients Aged 80 Years or Older

OBJECTIVES

Among kidney disease patients ≥80 years progressing to end-stage renal disease, there is growing interest in conservative nondialytic management approaches. However, among those who have initiated hemodialysis, little is known about the impact of withdrawal from dialysis on mortality, nor the patient characteristics associated with withdrawal from dialysis.

STUDY DESIGN

Historical cohort study.

SETTING AND PARTICIPANTS

We examined 133,162 incident hemodialysis patients receiving care within a large national dialysis organization from 2007 to 2011.

MEASURES

We identified patients who withdrew from dialysis, either as a listed cause of death or censor reason. Incidence rates and subdistribution hazard ratios for withdrawal from dialysis as well as 4 other censoring reasons were examined across age groups. In addition, demographic and clinical characteristics associated with withdrawal from dialysis therapy among patients ≥80 years old was assessed using logistic regression analysis.

RESULTS

Among 17,296 patients aged ≥80 years, 10% of patients withdrew from dialysis. Duration from the last hemodialysis treatment to death was 10 [interquartile range 6-16] days in patients with available data. Withdrawal from dialysis was the second and third most common cause of death among patients aged ≥80 years and <80 years, respectively. Among patients ≥80 years, minorities were much less likely than non-Hispanic whites to stop dialysis. Other factors associated with higher odds of dialysis withdrawal included having a central venous catheter compared to an arteriovenous fistula at dialysis start, dementia, living in mid-west regions, and less favorable markers associated with malnutrition-inflammation-cachexia syndrome such as higher white blood cell counts and lower body mass index, albumin, and normalized protein catabolic rate.

CONCLUSION/IMPLICATIONS

Among very-elderly incident hemodialysis patients, dialysis therapy withdrawal exhibits wide variations across age, race and ethnicity, regions, cognitive status, dialysis vascular access, and nutritional status. Further studies examining implications of withdrawal from dialysis in older patients are warranted.

Chronic dialysis in patients with end-stage renal disease: Relevance to kidney xenotransplantation

Renal allotransplantation clearly offers better survival and quality of life for end-stage renal disease (ESRD) patients than chronic dialysis. The median waiting time for a deceased donor kidney in a suitable ESRD patient is 3.9 years. The initial candidates for pig kidney xenotransplantation will be those with ESRD unlikely to receive an allograft within a reasonable period of time. It is thus reasonable to ascertain whether clinical trials of xenotransplantation might likewise offer superior outcomes. Chronic dialysis in patients with ESRD is associated with poor quality of life, significant morbidity, and relatively high mortality, with only 56% surviving 3 years and 42% at 5 years. However, a significant number of these patients, because of comorbidities, frailty, etc, would not be considered for renal allotransplantation and likely not for xenotransplantation. As genetically engineered pig kidneys have satisfactorily supported life in immunosuppressed nonhuman primates for many months or even more than a year, consideration in carefully selected patients could be given to pig kidney xenotransplantation. We suggest that, in order to give a patient the best possible outcome, the pig kidney could be transplanted pre-emptively (before dialysis is initiated). If it fails at any stage, the patient would then begin chronic dialysis and continue to await an allograft. The present (limited) evidence is that failure of a pig graft would not be detrimental to a subsequent allograft.

The Symptoms Prevalence, Medical Interventions, and Health Care Service Needs for Patients With End-Stage Renal Disease in a Renal Palliative Care Program

A retrospective study was conducted to evaluate the symptoms prevalence and interventions initiated in the last 2 weeks of life, health care service utilization, and causes of death of patients with end-stage renal disease (ESRD under a renal palliative care (RPC) program. A total of 335 RPC patients were included, of which 226 patients died during the study period. The 5 most prevalent symptoms were dyspnea (63.7%), fatigue (51.8%), edema (48.2%), pain (44.2%), and anorexia (38.1%); and the 5 most prevalent interventions initiated were oxygen (69.5%), parenteral infusion (67.3%), antibiotics (53.5%), bladder catheterization (44.7%), and analgesic (39.8%) in the last 2 weeks of life. Each patient received 3.5 ± 4.4 outpatient clinic visit, 3.4 ± 10.3 home care visits, and 3.1 ± 2.7 hospital admissions. Besides ESRD (51.8%), the most common causes of death were cardiovascular events (18.6%) and infection (17.2%).

Spirituality in Renal Supportive Care: A Thematic Review

Chronic kidney disease is marked by a reduced life expectancy and a high symptom burden. For those who reach end-stage renal disease, the prognosis is poor, and this combined with the growing prevalence of the disease necessitates supportive and palliative care programmes that will address people's psychosocial, cultural and spiritual needs. While there is variation between countries, research reveals that many renal specialist nurses and doctors are reluctant to address spirituality, initiate end-of-life conversations or implement conservative treatment plans early. Yet, other studies indicate that the provision of palliative care services, which includes the spiritual dimension, can reduce symptom burden, assist patients in making advanced directives/plans and improve health-related quality of life. This review brings together the current literature related to renal supportive care and spirituality under the following sections and themes. The introduction and background sections situate spirituality in both healthcare generally and chronic kidney disease. Gaps in the provision of chronic kidney disease spiritual care are then considered, followed by a discussion of the palliative care model related to chronic kidney disease and spirituality. Chronic kidney disease spiritual needs and care approaches are discussed with reference to advanced care planning, hope, grief and relationships. A particular focus on quality of life is developed, with spirituality named as a key dimension. Finally, further challenges, such as culture, training and limitations, are explicated.

Spiritual care and kidney disease in NZ: a qualitative study with New Zealand renal specialists

AIM

People with chronic kidney disease have a shortened life expectancy and carry a high symptom burden. Research suggests that attending to renal patients' spiritual needs may contribute to an improvement in their quality of life. The aim of this qualitative study was to investigate the provision of spiritual care in New Zealand renal units from the perspective of specialists.

METHODS

The study followed a generic qualitative approach and included semi-structured interviews with specialists recruited from New Zealand's ten renal centres.

RESULTS

Five specialist doctors and nine specialist nurses were recruited for interviews. Understandings of spirituality were broad, with most participants having an inclusive understanding. Patients' spiritual needs were generally acknowledged and respected though formal spiritual assessments were not done. Consideration of death was discussed as an often-unexamined need. The dominant position was that the specialists did not provide explicit spiritual care of patients but there was some ad hoc provision offered through pre-dialysis educators, family meetings, Māori liaison staff members and the efforts of individuals. Chaplains were well used in some services. Participants had received no pre and little in-service training or education in spiritual care. Suggestions for improvements included in-service training, better utilization of chaplaincy services and training in advance care planning.

CONCLUSION

Most participants indicated they would attempt to provide some form of spiritual care, either directly or by referring the patient to appropriate services. However, participants generally demonstrated a lack of confidence in addressing a patient's spiritual needs.

PAlliative Care in chronic Kidney diSease: the PACKS study--quality of life, decision making, costs and impact on carers in people managed without dialysis

Background

The number of patients with advanced chronic kidney disease opting for conservative management rather than dialysis is unknown but likely to be growing as increasingly frail patients with advanced renal disease present to renal services. Conservative kidney management includes ongoing medical input and support from a multidisciplinary team. There is limited evidence concerning patient and carer experience of this choice. This study will explore quality of life, symptoms, cognition, frailty, performance decision making, costs and impact on carers in people with advanced chronic kidney disease managed without dialysis and is funded by the National Institute of Health Research in the UK.

Methods

In this prospective, multicentre, longitudinal study, patients will be recruited in the UK, by renal research nurses, once they have made the decision not to embark on dialysis. Carers will be asked to ‘opt-in’ with consent from patients. The approach includes longitudinal quantitative surveys of quality of life, symptoms, decision making and costs for patients and quality of life and costs for carers, with questionnaires administered quarterly over 12 months. Additionally, the decision making process will be explored via qualitative interviews with renal physicians/clinical nurse specialists.

Discussion

The study is designed to capture patient and carer profiles when conservative kidney management is implemented, and understand trajectories of care-receiving and care-giving with the aim of optimising palliative care for this population. It will explore the interactions that lead to clinical care decisions and the impact of these decisions on informal carers with the intention of improving clinical outcomes for patients and the experiences of care givers.

[Effects of salvianolate combined with alprostadil and reduced glutathione on progression of chronic renal failure in patients with chronic kidney diseases: a long-term randomized controlled trial]

BACKGROUND

Effects of traditional Chinese medicine salvianolate combined with alprostadil and reduced glutathione on delay of progression in patients with acute kidney injury has been confirmed, but the role of this combination therapy on the progression of chronic renal failure is uncertain.

OBJECTIVE

To investigate the long-term effects of regular administration of salvianolate combined with Western medicine on the progression of chronic renal failure in patients with chronic kidney diseases (CKDs).

DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS

The study was performed at the ward of the Nephrology Department, Changhai Hospital, Second Military Medical University from August 2004 to October 2010. Thirty patients with CKDs at stage 2 to 4 and impaired renal function were recruited and randomly assigned to a treatment group or a control group, which consisted of 15 patients in each. Based on conventional therapy with the same oral medicines in the control group, patients in the treatment group were treated with salvianolate combined with alprostadil and reduced glutathione liquid intravenously for 7 to 10 d. Patients in the control group did not receive this combination therapy. The therapy was repeated monthly in patients in the treatment group. The follow-up time was an average of four years.

MAIN OUTCOME MEASURES

Assessment of renal function, count of white blood cells, and test of serum hemoglobin, electrolytes and albumin were performed before and every year after treatment. Study endpoints were the serum creatinine level doubled from baseline or receiving replacement therapy. Number of remaining patients in each group was calculated at the end of every year.

RESULTS

White blood cell count, serum albumin and electrocyte levels changed little in two groups after four years (P>0.05). Average serum hemoglobin levels in patients in the treatment group was elevated markedly compared with that in the control group after being treated for two years (P<0.01). The percentage of patients reaching the study termination in the treatment group (40%) decreased significantly compared with that (93%) in the control group (P<0.01).

CONCLUSION

The regular integrated traditional Chinese and Western medicine can effectively delay the deterioration of renal function in patients with CKDs over a period of four years.

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.

Spanish nephrology nurses' views and attitudes towards caring for dying patients

Patients with advanced chronic kidney disease are increasingly elderly with increasing numbers of co-morbidites. Some may not be suitable for dialysis, some will choose to withdraw from treatment after a period of time and some will reach the end of their lives while still on dialysis. Studies have shown nurses' attitudes towards caring for dying patients affect the quality of care. A descriptive study was conducted to explore Spanish nurses' views and attitudes in this context and to assess any relationship between demographic variables and attitudes. Two measurement tools were used: a demographic survey and the Frommelt Attitude Toward Care of the Dying Scale-Form B. Two hundred and two completed questionnaires were returned. Although respondents demonstrated positive attitudes in this domain, 88.9% viewed end-of-life (EOL) care as an emotionally demanding task, 95.3% manifested that addressing death issue require special skills and 92.6% reported that education on EOL care is necessary. This paper suggests strategies which could ease the burden in this area of care.

Is maximum conservative management an equivalent treatment option to dialysis for elderly patients with significant comorbid disease?

BACKGROUND AND OBJECTIVES

There is ongoing growth of elderly populations with ESRD in Western Europe and North America. In our center, we offer an alternative care pathway of 'maximum conservative management' (MCM) to patients who elect not to start dialysis, often because of a heavy burden of comorbid illness and advanced age. The objective of our study was to compare clinical outcomes for patients who had ESRD and chose either MCM or renal replacement therapy (RRT).

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

This is an observational study of a single-center cohort in the United Kingdom that evaluating 202 elderly (> or =70 yr) patients who had ESRD and had chosen either MCM (n = 29) or RRT (n = 173). We report survival, hospitalization rates, and location of death for this cohort. Survival was measured from a standardized 'threshold' estimated GFR of 10.8 ml/min per 1.73 m(2).

RESULTS

Median survival, including the first 90 d, was 37.8 mo (range 0 to 106 mo) for RRT patients and 13.9 mo (range 2 to 44) for MCM patients (P < 0.01). RRT patients had higher rates of hospitalization (0.069 [95% confidence interval (CI) 0.068 to 0.070]) versus 0.043 [95% CI 0.040 to 0.047] hospital days/patient-days survived) compared with MCM patients. MCM patients were significantly more likely to die at home or in a hospice (odds ratio 4.15; 95% CI 1.67 to 10.25). A survey of the literature describing elderly ESRD outcomes is also presented.

CONCLUSIONS

Dialysis prolongs survival for elderly patients who have ESRD with significant comorbidity by approximately 2 yr; however, patients who choose MCM can survive a substantial length of time, achieving similar numbers of hospital-free days to patients who choose hemodialysis.

Maintaining quality of life at the end of life in the end-stage renal disease population

The rapidly advancing age of incident dialysis patient has coincided with a rising mortality rate during the first year of dialysis. This is occurring despite a steady decline in mortality of prevalent patients. These statistics suggest that there is a subset of sick, elderly dialysis patients who will not survive the first 6 months of dialysis. It may be that these patients would be better served with a conservative, palliative approach that does not include initiation of dialysis. Even though hospice care is universally available to the Center for Medicare and Medicaid Services population, dialysis patients encounter many barriers to obtaining this benefit and have a hospice utilization rate only one quarter that of cancer patients. This article discusses the barriers to and goals of palliative care in the chronic kidney disease/end-stage renal disease population.

Dialysis discontinuation: quo vadis?

Approximately 1 in 4 deaths of patients maintained on dialysis in the United States is preceded by a decision to discontinue treatment. Once considered to be a form of suicide, dialysis discontinuation is now increasingly common in most countries that are fortunate enough to offer renal replacement therapies. Given an aging and progressively sicker chronic kidney disease patient population, the rate of terminating dialysis is likely to increase. The literature on dialysis discontinuation includes studies principally from Canada, the United Kingdom, and the United States. The research is reviewed, critiqued, and examined to determine its relevance to practice. Future issues include the need to explore variability in dialysis practice as well as employment of a more patient-centered approach that is consistent with modern palliative medicine.
