End-of-Life Issues

Caroline Etland

End of life has become an important clinical topic in critical care, although requisite improvements in end-of-life care have been slow to follow. Because the primary purpose of admission of patients to a critical care unit is to provide aggressive, lifesaving treatment, the death of a patient is generally regarded as a failure. Because the culture emphasizes saving lives, the language that describes the end of life employs negative terms, such as “forgoing life-sustaining treatments,” “do not resuscitate (DNR),” and “withdrawal of life support.” Sometimes the phrase withdrawal of care is used, which can cause families to think there will be no comfort measures or assistance provided after a decision is made to discontinue mechanical ventilation and other life-sustaining treatments. This lack of end-of-life language has hampered literature searches until recently. The medical subject headings (MeSH) term for withdrawal of life support is passive euthanasia. Content on the end of life in medical1 and nursing2 critical care textbooks is minimal. The first textbook on end of life in critical care was published in 19983 and the second in 2001.4 Recently, more accurate language has been used in health care and popular literature to describe end-of-life decision making and medical interventions, such as allow natural death instead of “do not resuscitate” and withholding of non-beneficial treatment in place of “futile care.”5,6 This shift toward more realistic descriptors reflects extensive recent research in health care, especially palliative care, and the effectiveness of goals-of-care discussions in people with serious illnesses prior to crisis events.

More attention is being given to the quality of the end-of-life experience of people with serious illnesses, particularly those who become critically ill. Recent studies suggest that “medical care for patients with advanced illness is characterized by inadequately treated physical distress; fragmented care systems; poor communication between doctors, patients, and families; and enormous strains on family caregiver and support systems.”7 In addition to health care system barriers to good end-of-life care, mainstream media has significantly influenced misconceptions among the American population about the success rate of medical interventions in seriously ill people. A familiar media presentation of life and death in the hospital is a critical event in a patient who is resuscitated and immediately awakens with full capacity. In reality, treatment options are usually explained in rapid technical language, followed by a frightening question, “Do you want us to keep going?” or “Tell us what you want us to do.” This heavy burden placed on loved ones means they must choose between treatment options, one of which may result in loss of their loved one.

The emphasis on patient autonomy as a valued ethical principle is deeply embedded in the health care system of the United States. Expert medical recommendations are offered to patients and families and they must determine in a brief space of time whether those recommendations are aligned with their personal values. Most nurses are familiar with the scenario of families of critical care unit patients who are told how well one body organ is functioning being unable to understand why another physician communicates a poor prognosis. Less often, families are provided with a longer-term perspective that addresses the loss of functional status, decreased quality of life, and potential need for long-term care. Hope is a powerful influence on decision making, and a shift from hope for recovery to hope for a peaceful death should be guided by clinicians with exemplary communication skills. Strategies for communicating with critically ill patients and their families are further described in Chapter 6 (Box 6-2). Critical care nurses are often the interpreters of medical information and how it applies to personal preferences and values. The ability to respond realistically in accordance with the listener’s values and culture is a learned skill. Fortunately, many resources are available to further develop the necessary skills to better support patients and families through a critical care unit admission to discharge. The American Association of Critical-Care Nurses (AACN) has recognized the importance of this aspect of care in the critical care unit by developing protocols for palliative and end-of-life issues in the critical care unit and by identifying palliative and end-of-life care as a major advocacy initiative.8,9 Several key resources to enhance communication and elicit goals of care will be discussed throughout this chapter.

This chapter focuses on the evidence available for the care rendered to the dying critical care patient and his or her family through research reports and summaries of research and guidelines. One such report is from the National Consensus Project and the National Quality Forum,10 in which the preferred practices of the imminently dying are discussed. This type of report can be used to make a checklist of indicators for quality improvement in end-of-life care. Other reports that are specific to the critical care unit have been written by groups headed by Teno,11 Nelson,12 Glavan,13 Beckstrand,14 and Mularski.15 Curtis and Rubenfeld4 have provided a “how to” guide for critical care quality improvement to outline the process that can be used with these indicators. More recently, the Center to Advance Palliative Care has created a resource site for implementing palliative care in the critical care unit.16

End-of-Life Experience in Critical Care

Attention to the end of life of hospitalized patients has increased since the publication of the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatment (SUPPORT).17 In this major report, more than 9000 seriously ill patients in five medical centers were studied. Despite an intervention to improve communication, shortcomings were found, aggressive treatment was common, only one half of physicians knew their patients’ preferences to avoid cardiopulmonary resuscitation (CPR), more than one third of patients who died spent at least 10 days in a critical care unit, and for 50% of conscious patients, family members reported moderate to severe pain at least one half of the time.

Following closely after the publication of the SUPPORT study, the Institute of Medicine (IOM) released a report, Approaching Death: Improving Care at the End of Life.18 The group detailed deficiencies in care and gave seven recommendations to improve care:

In SUPPORT and in the IOM report, critical care patients were not distinguished from other hospitalized patients, preventing distinctions to be made between types of units. To describe the number of deaths in critical care units, Angus and colleagues19 reviewed hospital discharge data from six states and the National Death Index. Of the more than 500,000 deaths studied, 38.3% were in hospitals, and 22% (59% of all hospital deaths) occurred after admission to the critical care unit. Terminal admissions associated with critical care accounted for 80% of all terminal hospitalization costs. The likelihood of dying in the hospital increased from age 25 to 74 years, and the likelihood of dying after critical care unit admission remained at 25% of all deaths for each age category.19 Although 90% of people would prefer to die in their own homes,18 more than 20% of those who died in this review received high-tech, aggressive care before they died.

An important shift in care of the terminally ill patient in the critical care unit has occurred with the growth of palliative care programs in the United States in the last decade. The rapid expansion of hospital-based palliative care programs has decreased the mortality rate in critical care units for patients followed by palliative care services through transfer to lower acuity, as well as decreased the costs associated with higher acuity critical care beds, pharmacy, laboratory, and diagnostic costs.20,21 Studies by Morrison and colleagues reviewed hospital and Medicare data to demonstrate that hospitals with palliative care services had significant cost savings in comparison to patients receiving usual care.21

Advance Directives

Although advance directives, also known as a living will or a health care power of attorney, were intended to ensure that patients received the care they desired at end of life, their enactment has been less than desired. Like other preventive measures, advance directives are underused, even though they are inexpensive and potentially effective.22 Completion rates in adults range from 16% to 36% overall with less than one half of seriously or terminally ill patients having documented their wishes.23 Most patients have expressed a desire to avoid “general life support” if dying or permanently unconscious, and few have expressed preferences regarding specific life-sustaining treatments; however, only about one third of physicians are aware of the existence of advance directives in their patients.24,25 Cook and others25 found that factors differed for determining the establishment of directives for advanced life support more than for informing a decision to limit or withdraw that support after admission to a critical care unit. Care providers also reported discomfort because they believed interventions were excessive and not compatible with an acceptable future quality of life. Even when advance directives are present, the question arises about whether they are applicable for current care decisions; in other words, is this a terminal illness?

Physician Orders for Life Sustaining Treatment

The Physician Orders for Life Sustaining Treatment (POLST) initiative began in Oregon in the 1990s when medical leaders collaborated to address the problem of patients’ advance directives not being honored.26 Different from an advance directive, POLST forms are medical orders that are honored across all treatment settings and are especially important to emergency responders in the community. Also, they are completed by the patient and physician in the presence of a serious chronic illness and should be incorporated into medical orders upon admission to the hospital or skilled nursing facility. POLST forms are more easily read than an advance directive in that the format is one of check boxes with specific directions. States that have approved use of POLST forms through legislation or specific regulations have witnessed a shift in proactive discussions of patients’ wishes for life-sustaining treatment.27,28 Preventing unwanted life-sustaining treatment through ongoing communication between patient and provider impacts the critical care setting in several ways. Treatment decision making is supported when prior discussions have occurred between physicians, patients, and their loved ones regarding declining health and limits on intervention. Resource utilization is maximized when inappropriate critical care unit admissions are prevented. Finally, moral distress of nurses is decreased when care is congruent with patient autonomy. Critical care nurses in states that recognize POLST forms need to be aware whether a regulatory mandate requires health care providers to honor the patient’s wishes documented on the form, or if the documentation is merely a guideline. Equally important is the need to identify the POLST form when it is presented and to communicate with medical staff to ensure that stated treatment wishes are incorporated into the plan of care.

Advance Care Planning

Cultural influences in the United States discourage discussion of death. Planning for decisions to be made at a later date if one is deemed incompetent is a difficult process, but this knowledge helps the family members left to make the treatment decisions. Advance care planning for those with chronic illness is advantageous for all involved.29 When surrogates hear the patient’s wishes for end-of-life care, they can be more congruent and knowledgeable about those wishes in future decision making. Significant effort has been expended on determining ideal interventions for the treatment and recovery from serious illnesses in the critical care setting. Currently, an equal amount of effort is being placed on providing adequate support and symptom management when recovery from illness is not likely to occur. This process may look different for individual patients or settings, but some guiding principles for a good death assist clinicians to identify what patients’ individual values are and where gaps in care exist that may be resolved (Box 11-1).30

Communication of the patient’s wishes between primary care providers and intensivists is critical. If patients have stated desires, they should be communicated when patients are transferred out of the critical care unit. If the patient has not specified his or her preferences, that information also is important and should be communicated to new health care providers; the level of care patients desire should be offered as appropriate. Families and care providers should be informed if patients decline aggressive care, so their families will not be left with difficult decisions in emergency situations. Emotional support for the patient and the family is important as they discuss advance care planning in the critical care setting and is described in the Nursing Interventions Classification (NIC) feature on Family Support in Box 6-3 in Chapter 6.

Ethical and Legal Issues

Legal and ethical principles guide many of our decisions in caring for the dying patient and the family. The patient is respected as autonomous and able to make his or her own decisions. When the patient is unable to make decisions, however, the same respect should be accorded to surrogates. These wishes might have been put in writing by the patient as an advance directive and preferably discussed with the surrogate. The Patient Self-Determination Act supports the patient’s right to control future treatment in the event the individual cannot speak for himself or herself.

Two of the basic principles underlying the provision of health care are beneficence and nonmaleficence. Beneficence is the principle of intending to benefit the other through one’s actions. Nonmaleficence means to do no harm. Sometimes at end of life, these two principles are in conflict, such as when resuscitation is attempted under beneficence but causes harm to the patient, especially if resuscitation was not desired by the patient. An equally troubling situation exists when the fear of liability drives decision making from the clinician’s perspective. Medical recommendations for limitation of life-sustaining treatment or comfort care often result in conflict with surrogate decision makers. When life-sustaining interventions are offered, even though they are likely to be unsuccessful, families are given hope that their loved one may respond and recover. In family conferences, a shift in language and dialogue to distinguish non-beneficial treatment from interventions that may produce long-lasting benefit after discharge should occur early in the critical care unit stay. Most physicians and nurses have not been taught how to conduct this type of dialogue in their training. Fortunately there are many more options to gain the training and experience necessary to shift the decision making from a purely clinical perspective to a more humanistic view. Programs such as Education in Palliative and End-of-life Care (EPEC), End of Life Nursing Education Consortium (ELNEC) and the Center to Advance Palliative Care’s Palliative Care Leadership Center (PCLC) training are cost-effective methods to educate and support clinicians to more effectively communicate with patients and families at the end of life. Additional information on ethical and legal issues can be found in Chapter 2, Ethical Issues and Chapter 3, Legal Issues.

Comfort Care

The decision to withdraw life-sustaining treatments and switch to comfort care at end of life should be made with as much involvement of the patient as possible, including physical presence of the patient in decision making or procuring paper documents if the patient is not able to participate. If neither option is available, the patient’s intent as understood from discussions or knowledge of the patient should guide the decision about whether to withdraw treatment. Withholding and withdrawing care are considered to be morally and legally equivalent.31 However, because families experience more stress in withdrawing treatments than in withholding them,32 treatments should not be started that the patient would not want or that would not benefit him or her.

The goal of withdrawal of life-sustaining treatments is to remove treatments that are not beneficial and may be uncomfortable. Any treatment in this circumstance may be withheld or withdrawn. After the goal of comfort has been chosen, each procedure should be evaluated to see if it is necessary or causes discomfort. Treatments that cause discomfort do not need to be continued. Another defining question is whether treatments are prolonging the dying process. When disagreements arise, ethics consultations have been found to resolve conflicts regarding inappropriately prolonged, non-beneficial, or unwanted treatments in the critical care unit, shifting the focus to more appropriate comfort care.33

Forgoing life-sustaining treatments is not the same as active euthanasia or assisted suicide. Killing is an action causing another’s death, whereas allowing a person to die by withholding or withdrawing life-sustaining treatment is avoiding any intervention that interferes with a natural death after illness or trauma.3

Cardiopulmonary Resuscitation

CPR was originally developed for those with coronary artery disease, and they are the most likely to survive resuscitation to discharge, as well as those who suffer cardiac arrest in the critical care unit.34 The benefits of resuscitation may be overestimated for survival and for the more relevant outcome of resumption of baseline functional status. In a meta-analysis of 51 studies, Ebell and colleagues34 found that the rate of overall survival to discharge after in-hospital CPR was 13.4%. A decreased rate of immediate survival was found for patients with acquired immune deficiency syndrome, those with a hematocrit above 35%, and patients who were male. Decreased survival to discharge was related to sepsis on the day before resuscitation, cancer with or without metastasis, dementia, elevated serum creatinine level, African American race, and dependent status. Brindley and colleagues35 found the same rate for overall survival to hospital discharge (13.4%) in a retrospective study of hospital charts for inpatients who had undergone or experienced resuscitation. A study from Norway found that only 17% of older adult patients older than 75 years survived resuscitation to return home.36 The survival rate for cancer patients has risen from 2% to 6.7% since 1990 perhaps because better treatment and support have transformed many cancers into chronic diseases.37 It has also become evident that critical care unit patients don’t survive CPR as often as ward patients and overall functional status declined 25% in all survivors.37

FitzGerald and others38 found that functional status among almost half of the survivors of in-hospital CPR had deteriorated compared with their condition 2 months before the event. After 6 months, 30% of those patients had died, and two thirds continued to lose function. Despite these dismal statistics, CPR is offered as an option without fully informing patients or families of the low possibility of survival, the pain and suffering involved during and after the procedure, and the potential for decline in functional status.

Family members typically are asked to leave the room during resuscitation. The American Association of Critical-Care Nurses (AACN)39 and the Emergency Nurses Association (ENA)40 have issued position statements recommending that families be allowed to be present during CPR and invasive procedures. Family presence is a significant source of support for the patient, and there may be a benefit to the family in observing the resuscitation that can aid in the grieving process when resuscitation is not successful by knowing that all was done that could be done.

Impact of Do Not Resuscitate Orders

As death approaches, the decision to initiate a DNR order is frequently delayed.41 A DNR order is intended to prevent the initiation of life-sustaining measures such as endotracheal intubation or CPR. In a review of the literature covering the 25 years since the DNR was established, Burns and colleagues42 found that those with a DNR order sometimes received less care and that some treatments were withheld43 without those changes being specified in the DNR order. Although acuity of illness and organ dysfunction consistently predicted mortality, only the medical history was positively associated with a DNR order for critically ill surgical patients.44 Documentation of consent conversations for DNR is less than ideal because the reasons for the DNR order were documented in only 55% of cases, and a consent conversation was documented in only 69%.45

Chang et al46 studied the effect of DNR orders in two critical care units in Taiwan and found that even though a DNR order was issued late in the clinical course, life-sustaining interventions were reduced through discussions and consent by surrogate decision makers. Nurses in Korea did not change their nursing activities substantially after receiving a DNR order, continuing to focus on maintenance, preventive, and hygiene tasks.47 They reported becoming more passive with interventions such as CVP monitoring, fluid and electrolyte balance, and reporting the patient’s condition. However, the nurses were more active in communicating with the family.

DNR is sometimes perceived to mean “do not care,” but that is not the intent. Families should be assured that patients will continue to receive care, including pain and symptom management, but that aggressive measures to extend life will not be employed. DNR orders should be written before withdrawal of life support is initiated; this documentation ensures that the patient is not subjected to unwanted interventions during the period between initiation of withdrawal and death.

Prognostication and Prognostic Tools

Why patients who are dying would have received life-prolonging therapy or aggressive interventions shortly before their death can be explained in part by a series of studies. It was found that physicians’ ability to prognosticate the length of time before death is limited48,49 and that the time to death usually is overestimated. Patients’ wishes are often not known, can be vague even when they are known,50 or change over the course of an illness.51 Care may not be in accordance with patients’ wishes, and this discrepancy is more prevalent when comfort care is desired over aggressive care.52 Skills in communication and end-of-life care that would enable providers to better assess patient and family wishes are poorly developed and are not emphasized in medical curricula.53,54

Severity scoring systems belong to one of five classes: prognostic, disease-specific, single-organ failure, trauma scores, and organ dysfunction.55 Two common tools for estimating critical care unit mortality are the Acute Physiology and Chronic Health Evaluation (APACHE) and multiple organ dysfunction score (MODS).56 However, when these tools were compared with physicians’ estimates of critical care unit survival of less than 10%, the physicians’ estimates were associated with subsequent life-support limitation. A physician’s estimate was more powerful in predicting mortality than illness severity, organ dysfunction, and use of inotropes or vasopressors.57

A majority of patients in the critical care unit have one or more chronic illnesses that greatly impact long-term recovery from major health events such as respiratory failure, myocardial infarction, or sepsis. In addition to use of prognostic tools specific to the critical care unit, it makes sense to incorporate prognostic tools for chronic illnesses into overall decision making and the communication process with patients and families. Scoring diagnoses with a traditionally poor prognosis or a consistent trajectory of functional decline can be helpful in comparing current health status with that which existed at the time of diagnosis. Loved ones of critically ill patients have witnessed the functional decline and may have hoped for improvement despite advancement of disease. Use of prognostic scales can add meaningful information to help patients and families make informed decisions. A summary of some of the more commonly used prognostic scales is listed in Table 11-1.58

Despite this information and these tools, uncertainty remains a major issue in decision making for physicians, patients, and families.51 Because of uncertainty and because a few patients who were never thought likely to survive actually return to visit a critical care unit, professionals are not confident about issues of survivability. Moreover, many families cling to small hopes of survival and recovery.

Communication and Decision Making

Communication with the patient and family is critical. White and colleagues59 found that shared decision making about end-of-life treatment choices in physician-family conferences was often incomplete, especially among less educated families. Families were found to go through a process in their decision making in which they considered the personal domain (rallying support and evaluating quality of life), the critical care unit environment domain (chasing the doctors and relating to the health care team), and the decision domain (arriving at a new belief and making and communicating the decision).60 Higher levels of shared decision making were associated with greater family satisfaction. Regardless of the health literacy of the patient or family, simple language explanations of life-sustaining treatments such as CPR, ventilation, and tube feedings are necessary to effectively communicate. Many patients and families experience a “data dump” during communication with health care providers who focus on reporting vital statistics and odds of success. Several organizations have made available education handouts—some in multiple languages—that explain life-sustaining treatments in realistic terms that are intended to be accompanied by health care provider discussion.61,62 Focusing on improving critical care unit communication when patients are dying reduces lengths of stay and resource use.63

Patient Communication

Patients’ capacity for decision making is limited by illness severity; they are too sick or are hampered by the therapies or medications used to treat them.64 When decision making is required, the patient is the first person to be approached. Information that can assist the clinical team to facilitate and support health-related decision making is provided in the NIC feature on Decision-Making Support in Box 2-3 in Chapter 2. When the patient is not able to safely make health care decisions because of disease progression or the therapy used for treatment, written documents such as a living will or a health care power of attorney should be obtained when possible. Additional information on power of attorney for health care can be found in the section on “Advance Care Planning” earlier in this chapter. Without those documents, wishes of the patient should be ascertained from those closest to the patient. Some states have a legal order of priority for surrogates. Some patients have neither capacity nor surrogates to assist in decision making, accounting for up to 27% of deaths in one study.65

Family Communication

How questions are asked of surrogates is extremely important. The question is not “What do you want to do about (patient’s name)?” but rather “What would (patient’s name) want if he knew he were in this situation?” These two questions have vastly different meanings and consequences for the patient and the family. The former question has a greater likelihood of engendering guilt over “pulling the plug.” The latter question provides a sense of fulfilling the patient’s wishes and respecting choices. Sometimes, this discussion is held during the family meeting, in which a general sense of goals can be discussed. As families make decisions, they appreciate support for those decisions, because the support can reduce the burden they experience. There is some evidence from a French study that families are reluctant to participate in decision making.66 This evidence reinforces the need to support families who are highly stressed and possibly exhausted while they are trying to make the most difficult decisions they have ever faced.

Family members have reported dissatisfaction with communication and decision making.67 Increasing the frequency of communication and sharing concerns early in the hospitalization will make subsequent discussions easier for the patient, family, and health professional. Having the entire critical care unit team present for morning rounds is one method of improving communication.68 Family members who understood the communication of staff were acknowledged and comforted by them; those who had difficulties drew back and received less adequate communication.69 Families who reported increased understanding when communicating with staff also reported greater acknowledgment and comfort from staff members, whereas families who experienced a lack of understanding when communicating with staff tended to withdraw, further limiting the effectiveness in communication with the hospital staff. Having to focus on understanding the professional is an unacceptable burden.

A publication from the Society of Critical-Care Medicine (SCCM) recommends supporting the families of critical care unit patients.70 Forty-three recommendations are presented, including an endorsement of a shared decision-making model, family care conferencing, culturally appropriate requests for truth-telling and informed refusal, spiritual support, staff education and debriefing, family presence at rounds and resuscitation, open and flexible visitation, family-friendly signs, and family support before, during, and after a death. One use of this guideline is to assess the level of family support for each critical care unit so that the most deficient recommendations could be addressed with quality-improvement actions. The categories used in this guideline are for general support of critical care unit families. When cross-indexed with seven end-of-life domains,71 the needs of a family with a dying patient are decision making; spiritual and cultural support; emotional and practical support of families, including visitation and family preparation for death; and continuity of care.72

Cultural and Spiritual Influences on Communication

Cultural and spiritual influences on attitudes and beliefs about death and dying differ dramatically. The cultures of the predominant religions commonly seen in the surrounding community should be familiar to the local health care team. These differences may affect how the health care team is viewed, how decisions are made, whether aggressive treatment is preferred, how death is met, and how grieving will occur.73,74 Patients who do not follow a particular religion should be assessed for their individual spiritual beliefs, or lack thereof. Identifying sources of spiritual comfort strengthens the bond between caregivers, patients, or family. Satisfaction with critical care unit care has been associated with the extent to which the family is satisfied with their spiritual care, especially when the patient is near death.75 Staff members’ own attitudes about the specific practices of a culture should be carefully assessed76 and should be tempered with respect and humility. Interpreters are necessary when the patient or the family members do not speak English. A cultural and religious assessment is warranted in all situations, because cultural or religious affiliation does not imply that patients or families follow all of the tenets of that group.

Withdrawal or Withholding of Treatment

Discussions about the potential for impending death are never held early enough. Usually, the first discussion about prognosis occurs in conjunction with the topic of the discontinuation of life support. The late timing of that first discussion is an issue, particularly because some families have arrived at the notion of withdrawal before physicians.64,77 Equally important is that some family members dread such conversations but are grateful to discuss the uncertainty of their loved one’s future. Physicians should give families time to adjust to this information and make preparations by providing discussions early about prognosis, goals of therapy, and the patient’s wishes.4

Proactive Approach

After a poor prognosis is established, a period can elapse before end-of-life treatment goals are determined. Campbell and Guzman78 recommended a proactive case-finding approach by palliative care personnel to decrease hospital length of stay for patients with multiorgan system failure and global cerebral ischemia. They shortened the time between identifying the poor prognosis and establishing comfort care goals, decreased length of critical care unit stay for patients with multisystem organ dysfunction, and reduced the cost of care. Proactive palliative care should occur when admission diagnoses trigger a consultation instead of after several avenues of treatment have been exhausted. Case managers and social workers can be particularly helpful in this regard.

When patients are admitted with serious illnesses and are likely to die, a proactive approach to palliative care has been found to shorten critical care unit stays without a significant difference in mortality rates or discharge disposition.79 The use of nonbeneficial resources decreased, and prolonged dying was avoided.78
