Patient attitudes and psychological considerations in dialysis discontinuation

Concurrent Care as the Next Frontier in End-of-Life Care

Importance

Hospice care is a unique type of medical care for people near the end of life and their families, with an emphasis on providing physical and psychological symptom management, spiritual care, and family caregiver support to promote quality of life. However, many people in the US who could benefit from hospice have very short stays or do not enroll at all due to current hospice policy. Changing policy to allow for concurrent availability of disease-directed therapy and hospice care-known as concurrent care-offers an opportunity to increase hospice use and lengths of stay.

Observations

Under Medicare payment policy, hospices are responsible for covering all costs related to patients' terminal conditions under a per diem rate. This payment structure has led to a de facto requirement that patients forgo costly therapies (including life-prolonging treatments or those with palliative intent) on enrollment in hospice because they are prohibitively expensive. In other countries, in Medicaid for children, and in the Veterans Health Administration in the US, there is greater flexibility in providing hospice services alongside life-prolonging care. Often paired with innovative payment models, concurrent care smooths practical, psychological, and physical care transitions when patient goals prioritize comfort. For example, allowing simultaneous receipt of hospice care and dialysis for people living with end-stage kidney disease-a group with relatively low hospice enrollment-can act as a bridge to hospice and potentially promote longer lengths of stay.

Conclusions and Relevance

Medicare and health care delivery systems are increasingly testing payment and care delivery models to improve hospice use via concurrent care, offering an important opportunity for innovation to better meet the needs of people living with serious illness and their families.

Patient and health care professional decision-making to commence and withdraw from renal dialysis: a systematic review of qualitative research

BACKGROUND AND OBJECTIVE

To ensure that decisions to start and stop dialysis in ESRD are shared, the factors that affect patients and health care professionals in making such decisions must be understood. This systematic review sought to explore how and why different factors mediate the choices about dialysis treatment.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

MEDLINE, Embase, CINAHL, and PsychINFO were searched for qualitative studies of factors that affect patients' or health care professionals' decisions to commence or withdraw from dialysis. A thematic synthesis was conducted.

RESULTS

Of 494 articles screened, 12 studies (conducted from 1985 to 2014) were included. These involved 206 patients (most receiving hemodialysis) and 64 health care professionals (age ranges: patients, 26-93 years; professionals, 26-61 years). For commencing dialysis, patients based their choice on "gut instinct," as well as deliberating over the effect of treatment on quality of life and survival. How individuals coped with decision-making was influential: Some tried to take control of the problem of progressive renal failure, whereas others focused on controlling their emotions. Health care professionals weighed biomedical factors and were led by an instinct to prolong life. Both patients and health care professionals described feeling powerless. With regard to dialysis withdrawal, only after prolonged periods on dialysis were the realities of life on dialysis fully appreciated and past choices questioned. By this stage, however, patients were physically dependent on treatment. As was seen with commencing dialysis, individuals coped with treatment withdrawal in a problem- or emotion-controlling way. Families struggled to differentiate between choosing versus allowing death. Health care teams avoided and queried discussions regarding dialysis withdrawal. Patients, however, missed the dialogue they experienced during predialysis education.

CONCLUSIONS

Decision-making in ESRD is complex and dynamic and evolves over time and toward death. The factors at work are multifaceted and operate differently for patients and health professionals. More training and research on open communication and shared decision-making are needed.

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.

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.

The creation of an advance care planning process for patients with ESRD

Comprehensive care of patients with end-stage renal disease (ESRD) requires expertise in advance care planning (ACP), including attention to ethical, psychosocial, and spiritual issues related to starting, continuing, withholding, and stopping dialysis therapy. ACP currently is under evolution from a document-driven decision-focused event. This article describes a new approach to ACP that emphasizes a relational patient-centered process that focuses on broader goals of care for a particular dialysis patient with known medical problems and is designed to serve as a guide to help nephrologists, social workers, and other health care professionals explore ACP discussions with their patients with ESRD. Specifically, we define ACP, highlight goals and key features of this facilitated ACP process, and provide an interview guide with examples of questions that can be used to explore the various aspects of ACP with patients and their families. Outcomes of such an ACP process will not be measured by increasing the number of completed advance directives, but by improving satisfaction with the entire end-of-life experience and having outcomes match patient preferences. It is expected that such a process will enhance shared decision making among patient, surrogate, and health care provider and help build strong and intimate relationships that can only serve to enhance end-of-life care. Throughout this process, patients are not abandoned as they confront the realities of declining health and functional status, but rather are supported through their illness and life on dialysis treatment.

Hope and advance care planning in patients with end stage renal disease: qualitative interview study

OBJECTIVE

To understand hope in the context of advance care planning from the perspective of patients with end stage renal disease.

DESIGN

Qualitative in-depth interview study.

SETTING

Outpatient department of a university affiliated nephrology programme.

PARTICIPANTS

19 patients with end stage renal disease purposively selected from the renal insufficiency, haemodialysis, and peritoneal dialysis clinics.

RESULTS

Patients' hopes were highly individualised and were shaped by personal values. They reflected a preoccupation with their daily lives. Participants identified hope as central to the process of advance care planning in that hope helped them to determine future goals of care and provided insight into the perceived benefits of advance care planning and their willingness to engage in end of life discussions. More information earlier in the course of the illness focusing on the impact on daily life, along with empowerment of the patient and enhancing professional and personal relationships, were key factors in sustaining patients' ability to hope. This helped them to imagine possibilities for a future that were consistent with their values and hopes. The reliance on health professionals to initiate end of life discussions and the daily focus of clinical care were seen as potential barriers to hope.

CONCLUSIONS

Facilitated advance care planning through the provision of timely appropriate information can positively enhance rather than diminish patients' hope. Current practices concerning disclosure of prognosis are ethically and psychologically inadequate in that they do not meet the needs of patients.

Facilitating advance care planning for patients with end-stage renal disease: the patient perspective

Comprehensive care of patients with ESRD requires expertise in advance care planning (ACP), including attention to ethical, psychosocial, and spiritual issues related to starting, continuing, withholding, and stopping dialysis. However, there are no standards of care regarding when to initiate or how to facilitate ACP. The purpose of this study was to determine the perspectives of patients with ESRD of the salient elements of ACP discussions. An ethnographic, qualitative, in-depth interview study was conducted of outpatients of a university-affiliated nephrology program. Twenty-four patients with ESRD were purposively selected from the renal insufficiency, hemodialysis, and peritoneal dialysis clinics. Establishing patient "buy-in" by identifying perceived benefits of ACP along with acknowledging patients' sense of personal empowerment were critical both for the effective framing of facilitated ACP and for determining patients' ability to participate in facilitated ACP. Patients required more information and earlier initiation of ACP discussions. Information needed to focus more on the individual and how his or her illness and interventions would affect his or her life and relationships and what he or she values most. Empathetic listening also was viewed as an integral component of facilitated ACP. Physicians clearly were seen as having the responsibility for initiating and guiding ACP. The role of patients and family within ACP is complex and varies significantly between patients. For most, family was an integral component of ACP, and many relied extensively on family to make end-of-life decisions. These findings identify a precarious tension between patients' preferences in terms of facilitated ACP and current clinical practice.

Quality end-of-life care in dialysis units

Quality end-of-life care has not been a priority in dialysis units and patients often experience prolonged dying while suffering needlessly. Advance directives (ADs) and decisions to stop dialysis have been highlighted by the medical profession as priorities in improving the quality of care, yet these are only two aspects of end-of-life care. They may not reflect patients' priorities and may not have the expected impact in improving the quality of end-of-life care. This review argues that quality end-of-life care should be a clinical priority in the care of dialysis patients; end-of-life care needs to be developed primarily from the patients' perspective; a clinical framework is required that integrates many aspects of end-of-life care; and end-of-life care should be initiated much earlier in the course of patients' illnesses than traditionally is done. By communicating more effectively and sooner with patients, their values and needs can be identified so we will be better able to plan and facilitate their end-of-life care and improve their experience of dying.

Urinary incontinence treatment preferences in long-term care

OBJECTIVE

To elicit preferences for different urinary incontinence (UI) treatments in long-term care (LTC) from groups likely to serve as proxy decision makers for LTC residents.

DESIGN

A descriptive, comparative study of preference for UI treatments of frail older adults, family members of nursing home (NH) residents, and LTC nursing staff. Surveys were mailed to families and self-administered by staff. Older adults were interviewed.

SETTING

Four LTC facilities and two residential-care facilities in Los Angeles.

PARTICIPANTS

Four hundred and three family members of incontinent NH residents were mailed surveys. Sixty-six nursing staff caring for these incontinent residents and 79 older adult residents of care facilities (nine cognitively intact NH respondents and 70 residential care residents) answered surveys.

MEASUREMENTS

Preference rankings between seven paired combinations of five different UI treatments were measured on an 11-point visual analog scale, with the verbal anchors "definitely prefer" this treatment, "probably prefer" this treatment, and "uncertain." Respondents gave open-ended comments as well.

RESULTS

Forty-two percent of family members (171/ 403) returned the mailed survey. Of all respondents, 85% "definitely" or "probably" preferred diapers, and 77% "definitely" or "probably" preferred prompted voiding (PV) to indwelling catheterization. Respondent groups occasionally differed significantly in their preferences. In choosing between treatment pairs using a visual analogue scale, nurses preferred PV to diapers significantly more than did older adults or families (both of whom preferred diapers) (F (2,295) = 13.11, P < .0001). Older adults, compared with family and nurse respondents, showed a significantly stronger preference for medications over diapers (F (2,296) = 41.54, P < .0001). In open-ended responses, older adults stated that they would choose a UI treatment based in part upon criteria of feeling dry, being natural, not causing embarrassment, being easy, and not resulting in dependence. Nurses said that they would base their choice of UI treatment upon increasing self-esteem and avoiding infection.

CONCLUSIONS

Although there was wide variation within and between groups about preferred UI treatment, most respondents preferred noninvasive strategies (diapers and PV) to invasive strategies (indwelling catheters and electrical stimulation). Older adults preferred to a greater degree medications and electrical stimulation, therapies directed at the underlying cause of UI. Despite data documenting that diapering is a less time intensive way to manage UI and that toileting programs are difficult to maintain in LTC, nurses viewed PV as "natural" and strongly preferred it to diapering. Several family members and older adults viewed PV as "embarrassing" and "fostering dependence." These data highlight the need to elicit preferences for UI treatment among LTC residents and their families.

Palliative Care/Hospice and the Withdrawal of Dialysis

While the majority of end-stage renal disease (ESRD) patients on dialysis lead satisfying lives, an increasing number are choosing to withdraw from dialysis before death. A partnership between nephrology and palliative care/hospice healthcare teams would seem likely in the care of ESRD patients, yet this is often not the case. In anticipation of increasing participation by palliative care/hospice teams in the care of such patients, this article reviews the decision-making process of withdrawal and the medical care of the patient who withdraws. While withdrawal can be an acceptable choice from a medical, legal, psychiatric, and ethical point of view, it can nonetheless be complex. Profound decisions are often characterized by the need for time to process, and by ambivalence among patient, family and healthcare providers. In addition to caring for the patient and family, the palliative care/hospice team will want to consider the needs of the referring nephrology team as well. A "uremic death" is characterized as painless; however, other symptoms related to the accumulation of toxins and fluid can be anticipated and managed. Pharmacological intervention of uremic symptoms, as well as the pain attendant to other, nonrenal comorbid disease is accomplished with awareness of the impact of renal failure on the excretion of various drugs and their metabolites.

Ethical issues in aging and renal disease

The incidence of elderly patients reaching end-stage renal disease (ESRD) and requiring renal replacement is increasing. Better medical care is helping patients live longer but, at the same time, is raising ethical questions. Treatment decisions for ESRD patients present a forum for the consideration of ethical questions surrounding the issues of scarce health care resource allocation and the withholding or withdrawal of life-sustaining treatment. As background for the consideration of ethical issues in ESRD patients, the quality of life they experience and what they may expect as death approaches also are discussed.

Doctors in limbo: the United States 'DNR' debate

Cardiopulmonary resuscitation is unlike any other medical intervention in its emotional impact. Its original use in reversible conditions has been replaced by its expected use in irreversible ones. The history of this transformation and its psychological concommitants are reviewed. New York State is unusual in having a 'DNR' law where resuscitation is the default position unless actively refused by patient or surrogate. The paradoxical genesis of this law, and its complex effect on a tertiary care hospital are described. Attention is focused on the emotional stresses on medical staff, and the extensive teaching program mounted by the institution's ethics committee to enable a positive adaptation. The difficulties inherent in surrogate decision-making are also reviewed.

Psychiatry and bioethics. An exploration of the relationship

Psychiatrists have been extensively involved in ethics in the general hospital over the past two decades and have functioned in that area in a variety of roles. The basis for psychiatry's strong interest in bioethics can be understood as related to three factors: familiarity with many of the clinical problems that lead to bioethics consultation, the frequent importance of psychiatric aspects of ethics, and the observation that psychiatrists already possess many of the clinical skills necessary for doing ethics work. The particular value of training psychiatrists to serve as ethics consultants, in addition to the importance of their continuing role on hospital ethics committees, is discussed.

Denying the dying. Advance directives and dialysis discontinuation

A structured interview was administered to a sample of patients on maintenance dialysis and their attending physicians to obtain information on the documentation of their end-of-life treatment preferences. The majority of the patients reported never having considered stopping dialysis, or having discussed with their nephrologist or family the circumstances in which treatment should be discontinued. Only 7 patients (6%) had completed an advance directive; these patients were all men (P = 0.01) and tended to be better educated (P = 0.02). Only one of the nine physicians had completed an advance directive. In most cases, the dialysis patients and their treatment team staff were preoccupied with the struggles of daily life and had avoided or denied considerations of terminal illness and death. The literature on denial, medical illness, and dying is also reviewed as it relates to dialysis patients, end-of-life treatment, and terminal care.

Withdrawal from dialysis: a review with an emphasis on the black experience

Withdrawal from dialysis has been shown to be a common occurrence in treated end-stage renal disease. Interestingly, there have been several reports documenting that blacks withdraw from dialysis one half to one third the rate of whites. There has been little research into the reasons for this marked discrepancy. This article reviews the existing literature on the different rates of withdrawal in blacks compared with whites. It then draws on a broad range of literature, including sociology, psychiatry, and anthropology, to propose possible reasons for the differences. From this review, it would seem that both medical and cultural factors play important roles in the decisions about withdrawal, but that cultural beliefs and attitudes are more important. More research is needed in both the medical and cultural aspects of rates of withdrawal to help explain the observed differences in blacks compared with whites.
