Withholding and withdrawing dialysis in the intensive care unit: benefits derived from consulting the renal physicians association/american society of nephrology clinical practice guideline, shared decision-making in the appropriate initiation of and withdrawal from dialysis

Acute kidney injury requiring dialysis in children: a multicentric, emerging country perspective

BACKGROUND

Acute kidney injury (AKI) is a life-threatening condition, especially in extreme age groups and when kidney replacement therapy (KRT) is necessary. Studies worldwide report mortality rates of 10-63% in pediatric patients undergoing KRT.

METHODS

Over 13 years, this multicenter study analyzed data from 693 patients with AKI, all receiving KRT, across 74 hospitals and medical facilities in Rio de Janeiro, Brazil.

RESULTS

The majority were male (59.5%), under one year old (55.6%), and treated in private hospitals (76.5%). Sixty-six percent had comorbidities. Pneumonia and congenital heart disease were the most common admission diagnoses (21.5% and 20.2%, respectively). The mortality rate was 65.2%, with lower rates in patients over 12 years (50%). Older age was protective (HR: 2.35, IQR [1.52-3.62] for neonates), and primary kidney disease had a three-fold lower mortality rate. ICU team experience (HR: 0.74, IQR [0.60-0.91]) correlated with lower mortality, particularly in hospitals treating 20 or more patients. Among the deceased, 40% died within 48 h of KRT initiation, suggesting possible late referral or treatment futility.

CONCLUSIONS

This study confirms the high mortality in pediatric dialytic AKI in middle-income countries, underlining early mortality and offering critical insights for improving outcomes.

Advance Care Planning, Shared Decision Making, and Serious Illness Conversations in Onconephrology

Advance care planning, shared decision making, and serious illness conversations are communication processes designed to promote patient-centered care. In onconephrology, patients face a series of complex medical decisions regarding their care at the intersection of oncology and nephrology. Clinicians who aim to ensure that patient preferences and values are integrated into treatment planning must work within a similarly complex care team comprising multiple disciplines. In this review, we describe key decision points in a patient's care trajectory, as well as guidance on how and when to engage in advance care planning, shared decision making, and serious illness discussions. Further research on these processes in the complex context of onconephrology is needed.

Indications for and Timing of Initiation of KRT

KRT is considered for patients with severe AKI and associated complications. The exact indications for initiating KRT have been debated for decades. There is a general consensus that KRT should be considered in patients with AKI and medically refractory complications ("urgent indications"). "Relative indications" are more common but defined with less precision. In this review, we summarize the latest evidence from recent landmark clinical trials, discuss strategies to anticipate the need for KRT in individual patients, and propose an algorithm for decision making. We emphasize that the decision to consider KRT should be made in conjunction with other forms of organ support therapies and important nonkidney factors, including the patient's preferences and overall goals of care. We also suggest future research to differentiate patients who benefit from timely initiation of KRT from those with imminent recovery of kidney function. Until then, efforts are needed to optimize the initiation and delivery of KRT in routine clinical practice, to minimize nonessential variation, and to ensure that patients with persistent AKI or progressive organ failure affected by AKI receive KRT in a timely manner.

Palliative Care for Patients with Kidney Disease

Interest in palliative care has increased in recent times, particularly in its multidisciplinary approach developed to meet the needs of patients with a life-threatening disease and their families. Although the modern concept of palliative simultaneous care postulates the adoption of these qualitative treatments early on during the life-threatening disease (and potentially just after the diagnosis), palliative care is still reserved for patients at the end of their life in most of the clinical realities, and thus is consequently mistaken for hospice care. Patients with acute or chronic kidney disease (CKD) usually experience poor quality of life and decreased survival expectancy and thus may benefit from palliative care. Palliative care requires close collaboration among multiple health care providers, patients, and their families to share the diagnosis, prognosis, realistic treatment goals, and treatment decisions. Several approaches, such as conservative management, extracorporeal, and peritoneal palliative dialysis, can be attempted to globally meet the needs of patients with kidney disease (e.g., physical, social, psychological, or spiritual needs). Particularly for frail patients, pharmacologic management or peritoneal dialysis may be more appropriate than extracorporeal treatment. Extracorporeal dialysis treatment may be disproportionate in these patients and associated with a high burden of symptoms correlated with this invasive procedure. For those patients undergoing extracorporeal dialysis, individualized goal setting and a broader concept of adequacy should be considered as the foundations of extracorporeal palliative dialysis. Interestingly, little evidence is available on palliative and end of life care for acute kidney injury (AKI) patients. In this review, the main variables influencing medical decision-making about palliative care in patients with kidney disease are described, as well as the different approaches that can fulfill the needs of patients with CKD and AKI.

Cause of death for people with end-stage kidney disease withdrawing from treatment in Australia and New Zealand

BACKGROUND

Withdrawal from renal replacement therapy is common in patients with end-stage kidney disease (ESKD), but end-of-life service planning is challenging without population-specific data. We aimed to describe mortality after treatment withdrawal in Australian and New Zealand ESKD patients and evaluate death-certified causes of death.

METHODS

We performed a retrospective cohort study on incident patients with ESKD in Australia, 1980-2013, and New Zealand, 1988-2012, from the Australian and New Zealand Dialysis and Transplant registry. We estimated mortality rates (by age, sex, calendar year and country) and summarized withdrawal-related deaths within 12 months of treatment modality change. Certified causes of death were ascertained from data linkage with the Australian National Death Index and New Zealand Mortality Collection database.

RESULTS

Of 60 823 patients with ESKD, there were 8111 treatment withdrawal deaths and 26 207 other deaths over 381 874 person-years. Withdrawal-related mortality rates were higher in females and older age groups. Rates increased between 1995 and 2013, from 1142 (95% confidence interval 1064-1226) to 2706/100 000 person-years (95% confidence interval 2498-2932), with the greatest increase in 1995-2006. A third of withdrawal deaths occurred within 12 months of treatment modality change. The national death registers reported kidney failure as the underlying cause of death in 20% of withdrawal cases, with other causes including diabetes (21%) and hypertensive disease (7%). Kidney disease was not mentioned for 18% of withdrawal patients.

CONCLUSIONS

Treatment withdrawal represents 24% of ESKD deaths and has more than doubled in rate since 1988. Population data may supplement, but not replace, clinical data for end-of-life kidney-related service planning.

The clinical practice guideline palliative care for children and other strategies to enhance shared decision-making in pediatric palliative care; pediatricians' critical reflections

Background

Because of practice variation and new developments in palliative pediatric care, the Dutch Association of Pediatrics decided to develop the clinical practice guideline (CPG) palliative care for children. With this guideline, the association also wanted to precipitate an attitude shift towards shared decision-making (SDM) and therefore integrated SDM in the CPG Palliative care for children. The aim was to gain insight if integrating SDM in CPGs can potentially encourage pediatricians to practice SDM. Its objectives were to explore pediatricians’ attitudes and thoughts regarding (1) recommendations on SDM in CPGs in general and the guideline Palliative care for children specifically; (2) other SDM enhancing strategies or tools linked to CPGs.

Methods

Semi-structured face-to-face interviews. Pediatricians (15) were recruited through purposive sampling in three university-based pediatric centers in the Netherlands. The interviews were audio-recorded and transcribed verbatim, coded by at least two authors and analyzed with NVivo.

Results

Some pediatricians considered SDM a skill or attitude that cannot be addressed by clinical practice guidelines. According to others, however, clinical practice guidelines could enhance SDM. In case of the guideline Palliative care for children, the recommendations needed to focus more on how to practice SDM, and offer more detailed recommendations, preferring a recommendation stating multiple options. Most interviewed pediatricians felt that patient decisions aids were beneficial to patients, and could ensure that all topics relevant to the patient are covered, even topics the pediatrician might not consider him or herself, or deems less important. Regardless of the perceived benefit, some pediatricians preferred providing the information themselves instead of using a patient decision aid.

Conclusions

For clinical practice guidelines to potentially enhance SDM, guideline developers should avoid blanket recommendations in the case of preference sensitive choices, and SDM should not be limited to recommendations on non-treatment decisions. Furthermore, preference sensitive recommendations are preferably linked with patient decision aids.

Do-not-resuscitate and treatment limitation decisions - Six years of experience from a Portuguese General Intensive Care Unit

OBJECTIVE

Treatment limitation, as well as do-not-resuscitate (DNR) directives, are difficult but important to improve patients' quality of life and minimize dysthanasia. We aimed to study the approach to withholding, withdrawal, and DNR decisions, patients' characteristics, and process documentation in a general Intensive Care Unit (ICU) in Portugal.

METHODS

A retrospective analysis of data regarding the limitation of treatment decisions collected from previously-designed forms and complemented by medical record consultation.

RESULTS

A total of 1602 patients were admitted to the ICU between 2011 and 2016. DNR decisions were documented in 127 cases (7.9%). Patients with treatment limitations were older and had higher Simplified Acute Physiology Score II. The most frequent diagnosis preceding these decisions was sepsis (52.0%, n = 66); the most common main reason for limiting treatment was a poor prognosis of acute illness. Of the patients to whom a DNR was implemented, 117 (92.1%) died in the ICU (40.1% of the total number of ICU deaths), and hospital mortality was 100%. Participants in these decisions, as well as types of treatment withdrawn and their respective timings, were not registered in medical records.

CONCLUSION

Treatment limitation and DNR decisions were relatively common, in line with other Southern European studies, but behind Northern European and North American centers. Patients with these limitations were older and more severely ill than patients without such decisions. Documentation of these processes should be clear and detailed, either in specific forms or computerized clinical records; there is room for improvement in this area.

Current controversies and irresolvable disagreement: the case of Vincent Lambert and the role of 'dissensus'

Controversial cases in medical ethics are, by their very nature, divisive. There are disagreements that revolve around questions of fact or of value. Ethical debate may help in resolving those disagreements. However, sometimes in such cases, there are opposing reasonable views arising from deep-seated differences in ethical values. It is unclear that agreement and consensus will ever be possible. In this paper, we discuss the recent controversial case of Vincent Lambert, a French man, diagnosed with a vegetative state, for whom there were multiple court hearings over a number of years. Both family and health professionals were divided about whether artificial nutrition and hydration should be withdrawn and Lambert allowed to die. We apply a 'dissensus' approach to his case and argue that the ethical issue most in need of scrutiny (resource allocation) is different from the one that was the focus of attention.

Palliative care for acute kidney injury patients in the intensive care unit

Patients with acute kidney injury (AKI) in the intensive care unit (ICU) are often suitable for palliative care due to the high symptom burden. The role of palliative medicine in this patient population is not well defined and there is a lack of established guidelines to address this issue. Because of this, patients in the ICU with AKI deprived of the most comprehensive or appropriate care. The reasons for this are multifactorial including lack of palliative care training among nephrologists. However, palliative care in these patients can help alleviate symptoms, improve quality of life, and decrease suffering. Palliative care physicians can determine the appropriateness and model of palliative care. In addition to shared decision-making, advance directives should be established with patients early on, with specific instructions regarding dialysis, and those advance directives should be respected.

New concepts in palliative care in the intensive care unit

Some patients admitted to an intensive care unit may face a terminal illness situation, which usually leads to death. Knowledge of palliative care is strongly recommended for the health care providers who are taking care of these patients. In many situations, the patients should be evaluated daily as the introduction of further treatments may not be beneficial to them. The discussions among health team members that are related to prognosis and the goals of care should be carefully evaluated in collaboration with the patients and their families. The adoption of protocols related to end-of-life patients in the intensive care unit is fundamental. A multidisciplinary team is important for determining whether the withdrawal or withholding of advanced care is required. In addition, patients and families should be informed that palliative care involves the best possible care for that specific situation, as well as respect for their wishes and the consideration of social and spiritual backgrounds. Thus, the aim of this review is to present palliative care as a reasonable option to support the intensive care unit team in assisting terminally ill patients. Updates regarding diet, mechanical ventilation, and dialysis in these patients will be presented. Additionally, the hospice-model philosophy as an alternative to the intensive care unit/hospital environment will be discussed.

[Extracorporeal renal replacement therapy in acute kidney injury : Recommendations from the renal section of the DGIIN, ÖGIAIN and DIVI]

BACKGROUND

Acute kidney injury (AKI) is a common complication in intensive care unit (ICU) patients. The incidence of AKI in ICU patients exceeds 50% and the associated morbidity and mortality rates increase with severity of AKI. In addition, long-term consequences of AKI are underestimated and several studies show impaired long-term outcome after AKI. In about 5-25% of ICU patients with AKI renal replacement therapy (RRT) is required.

OBJECTIVES

To assist in indication, timing, modality and application of renal replacement therapy of adult patients, current recommendations from the renal sections of the DGIIN (Deutschen Gesellschaft für Internistische Intensivmedizin und Notfallmedizin), ÖGIAIN (Österreichischen Gesellschaft für Internistische und Allgemeine Intensivmedizin und Notfallmedizin) and DIVI (Deutschen Interdisziplinären Vereinigung für Intensiv- und Notfallmedizin) are stated.

MATERIALS AND METHODS

The recommendations stated in this paper are based on the current KDIGO (Kidney Disease: Improving Global Outcomes) guidelines, recommendations from the 17th Acute Disease Quality Initiative (ADQI) Consensus Group, the French Intensive Care Society (SRLF) with the French Society of Anesthesia Intensive Care (SFAR) and the expert knowledge and clinical experience of the authors.

RESULTS

Today, different treatment modalities for RRT are available. Although continuous RRT and intermittent dialysis therapy as well as continuous dialysis therapy have comparable outcomes, differences exist with respect to practical application as well as health-economic aspects. Individualized risk stratification might be helpful to choose the right time to start and the right treatment modality for patients.

Effects of continuous and intermittent renal replacement therapies among adult patients with acute kidney injury

Background: Dialysis-dependent acute kidney injury (AKI) can be treated using continuous (CRRT) or intermittent renal replacement therapies (IRRT). Although some studies suggest that CRRT may have advantages over IRRT, study findings are inconsistent. This study assessed differences between CRRT and IRRT regarding important clinical outcomes (such as mortality and renal recovery) and cost-effectiveness. Additionally, ethical aspects that are linked to renal replacement therapies in the intensive care setting are considered.

Methods: Systematic searches in MEDLINE, EMBASE, and Cochrane Library including RCTs, observational studies, and cost-effectiveness studies were performed. Results were pooled using a random effects-model.

Results: Forty-nine studies were included. Findings show a higher rate of renal recovery among survivors who initially received CRRT as compared with IRRT. This advantage applies to the analysis of all studies with different observation periods (Relative Risk (RR) 1.10; 95% Confidence Interval (CI) [1.05, 1.16]) and to a selection of studies with observation periods of 90 days (RR 1.07; 95% CI [1.04, 1.09]). Regarding observation periods beyond there are no differences when only two identified studies were analyzed. Patients initially receiving CRRT have higher mortality as compared to IRRT (RR 1.17; 95% CI [1.06, 1.28]). This difference is attributable to observational studies and may have been caused by allocation bias since seriously ill patients more often initially receive CRRT instead of IRRT. CRRT do not significantly differ from IRRT with respect to change of mean arterial pressure, hypotensive episodes, hemodynamic instability, and length of stay. Data on cost-effectiveness is inconsistent. Recent analyzes indicate that initial CRRT is cost-effective compared to initial IRRT due to a reduction of the rate of long-term dialysis dependence. As regards a short time horizon, this cost benefit has not been shown.

Conclusion: Findings of the conducted assessment show that initial CRRT is associated with higher rates of renal recovery. Potential long-term effects on clinical outcomes for more than three months could not be analyzed and should be investigated in further studies. Economical analyzes indicate that initial CRRT is cost-effective when costs of long-term dialysis dependence are considered. However, transferability of the economic analyzes to the German health care system is limited and the conduction of economical analyzes using national cost data should be considered.

Preliminary Identification of Coping Profiles Relevant to Surrogate Decision Making in the ICU

Objective

The Intensive Care Unit (ICU) is a stressful environment for families of critically ill patients and these individuals are at risk to develop persistent psychological morbidity. Our study objective was to identify individual differences in coping with stress and information presentation preferences of respondents exposed to a simulated ICU experience.

Methods

Participants were recruited from a university and two community populations. Participants completed questionnaires that measured demographic information and characteristics that may be relevant to an individual’s ICU experience. Quality of life was measured by the EQ-5D, personality dimensions were examined with the abbreviated Big Five inventory, coping with stress was assessed with Brief COPE. Shared decision making preferences were assessed by the Degner Control Preferences Scale (CPS) and information seeking style was assessed with the Miller Behavioral Style Scale (MBSS). Social support was examined using an abbreviated version of the Social Relationship Index. Participants also completed a vignette-based simulated ICU experience, in which they made a surrogate decision on behalf of a loved one in the ICU.

Results

Three hundred forty-three participants completed the study. Three distinct coping profiles were identified: adaptive copers, maladaptive copers, and disengaged copers. Profiles differed primarily on coping styles, personality, quality of their closest social relationship, and history of anxiety and depression. Responses to the simulated ICU decision making experience differed across profiles. Disengaged copers (15%) were more likely to elect to refuse dialysis on behalf of an adult sibling compared to adaptive copers (7%) or maladaptive copers (5%) (p = 0.03). Notably, the MBSS and the CPS did not differ by coping profile.

Conclusion

Distinct coping profiles are associated with differences in responses to a simulated ICU experience. Tailoring communication and support to specific coping profiles may represent an important pathway to improving ICU experience for patients and families.

Improving End-of-Life Care Prognostic Discussions

Research has validated the desire of patients and families for ongoing prognostic information; however, few conversations occur before patients reach the advanced stages of their disease trajectory. Physician hesitance and delay in discussing unfavorable prognoses deny patients and families optimal time to prepare for critical decision making. Advanced practice registered nurses can play a crucial, complementary role with the critical care interdisciplinary team to implement strategies to improve communication about prognosis and end of life with patients and families. Clinicians should discuss deterioration in disease-specific characteristics and changes (decline) in functional status. Functional status can serve as an accurate guide for forecasting prognosis, particularly in patients with heart failure, stroke, chronic lung disease, and end-stage renal disease. This article provides an overview of effective intensive care unit prognostic systems and discusses barriers and opportunities for nurses to use evidence-based knowledge related to disease trajectory and prognosis to improve communication and the quality of palliative and end-of-life care for patients.

Ethics and health policy of dialyzing a patient in a persistent vegetative state

Each year, out-of-hospital cardiac arrests occur in approximately 300,000 Americans. Of these patients, less than 10% survive. Survivors often live with neurologic impairments that neurologists classify as anoxic-ischemic encephalopathy (AIE). Neurologic impairments under AIE can vary widely, each with unique outcomes. According to the American Academy of Neurology Practice Parameter paper, the definition of poor outcome in AIE includes death, persistent vegetative state (PVS), or severe disability requiring full nursing care 6 months after event. In a recent survey, participants deemed an outcome of PVS as "worse than dead." Lay persons' assessments of quality of life for those in a PVS provide assistance for surrogate decision-makers who are confronted with the clinical decision-making for a loved one in a PVS, whereas clinical practice guidelines help health care providers to make decisions with patients and/or families. In 2000, the Renal Physicians Association and the American Society of Nephrology published a clinical practice guideline, "Shared Decision-Making in the Appropriate Initiation of and Withdrawal from Dialysis." In 2010, after advances in research, a second edition of the guideline was published. The updated guideline confirmed the recommendation to withhold or withdraw ongoing dialysis in "patients with irreversible, profound neurological impairments such that they lack signs of thought, sensation, purposeful behavior and awareness of self and environment," such as found in patients with PVS. Here, the authors discuss the applicability of this guideline to patients in a PVS. In addition, they build on the guideline's conception of shared decision-making and discuss how continued dialysis violates ethical and legal principles of care in patients in a PVS.

Selecting renal replacement therapies: what do African American and non-African American patients and their families think others should know? A mixed methods study

Background

Little is known regarding the types of information African American and non-African American patients with chronic kidney disease (CKD) and their families need to inform renal replacement therapy (RRT) decisions.

Methods

In 20 structured group interviews, we elicited views of African American and non-African American patients with CKD and their families about factors that should be addressed in educational materials informing patients’ RRT selection decisions. We asked participants to select factors from a list and obtained their open-ended feedback.

Results

Ten groups of patients (5 African American, 5 non-African American; total 68 individuals) and ten groups of family members (5 African American, 5 non-African American; total 62 individuals) participated. Patients and families had a range (none to extensive) of experiences with various RRTs. Patients identified morbidity or mortality, autonomy, treatment delivery, and symptoms as important factors to address. Family members identified similar factors but also cited the effects of RRT decisions on patients’ psychological well-being and finances. Views of African American and non-African American participants were largely similar.

Conclusions

Educational resources addressing the influence of RRT selection on patients’ morbidity and mortality, autonomy, treatment delivery, and symptoms could help patients and their families select RRT options closely aligned with their values. Including information about the influence of RRT selection on patients’ personal relationships and finances could enhance resources’ cultural relevance for African Americans.

Withholding and withdrawing renal support in acute kidney injury

Management of critically ill patients with acute kidney injury (AKI) is mainly limited to supportive therapy, with dialysis as one of the main components. Whether or not to offer dialysis and when to withdraw dialysis is a one of the many choices physicians face in daily clinical practice. Withholding or withdrawing renal replacement therapy is a complex decision and depends on many interacting factors, which are unique for each patient and their families and for the care team. An evidence-based guideline with nine specific recommendations for managing patients has been available however is infrequently employed to help clinical decision making. In this review, we discuss the important issues affecting decisions to withhold or withdraw dialysis in AKI patients and provide an approach for making these decisions for patient management.

An advance directive in two questions

It has been two decades since advance directives have become an integral part of health care. Impediments to their optimal usage are common and multifactorial. Decisions commonly have to be made when patients are unable to do so or choose not to participate in decision making, often at the end of life. The use of two questions, 1) "If you cannot, or choose not to participate in health care decisions, with whom should we speak?" and 2) "If you cannot, or choose not to participate in decision making, what should we consider when making decisions about your care?," may accomplish the major goals of an advance directive.

Identifying critically ill patients with acute kidney injury for whom renal replacement therapy is inappropriate: an exercise in futility?

Clinicians treating critically ill patients must consider the possibility that painful and expensive aggressive treatments might confer negligible benefit. Such treatments are often described as futile or inappropriate. We discuss the problem of deciding whether to initiate renal replacement therapy (RRT) for critically ill patients with acute kidney injury (AKI) in the context of the debate surrounding medical futility. The main problems in deciding when such treatment would be futile are that the concept itself is controversial and eludes quantitative definition, that available outcome data do not allow confident identification of patients who will not benefit from treatment and that the decision on RRT in a critically ill patient with AKI is qualitatively different from decisions on other modalities of intensive care and resuscitation, as well as from decisions on dialysis for chronic kidney disease. Despite these difficulties, nephrologists need to identify circumstances in which continued aggressive care would be futile before proceeding to initiate RRT.
