Withdrawing and withholding life-sustaining therapies are not the same

End-of-life Care in the Intensive Care Unit and Ethics of Withholding/Withdrawal of Life-sustaining Treatments

The medical progress has produced improvements in critically ill patients' survival to early phases of life-threatening diseases, thus producing long intensive care stays and persisting disability, with uncertain long-term survival rates and quality of life. Thus, compassionate end-of-life care and the provision of palliative care, even overlapping with the most aggressive of curative intensive care unit (ICU) care has become crucial. Moreover, withdrawal or withholding of life-sustaining treatment may be adopted, allowing unavoidable deaths to occur, without prolonging agony or ICU stay. Our aim was to summarize the key element of end-of-life care in the ICU and the ethics of withholding/withdrawal life-sustaining treatments.

Differences in directives to limit treatment and discontinue mechanical ventilation between elderly and very elderly patients: a substudy of a multinational observational study

PURPOSE

The aim of this study was to characterize differences in directives to limit treatments and discontinue invasive mechanical ventilation (IMV) in elderly (65-80 years) and very elderly (> 80 years) intensive care unit (ICU) patients.

METHODS

We prospectively described new written orders to limit treatments, IMV discontinuation strategies [direct extubation, direct tracheostomy, spontaneous breathing trial (SBT), noninvasive ventilation (NIV) use], and associations between initial failed SBT and outcomes in 142 ICUs from 6 regions (Canada, India, United Kingdom, Europe, Australia/New Zealand, United States).

RESULTS

We evaluated 788 (586 elderly; 202 very elderly) patients. Very elderly (vs. elderly) patients had similar withdrawal orders but significantly more withholding orders, especially cardiopulmonary resuscitation and dialysis, after ICU admission [67 (33.2%) vs. 128 (21.9%); p = 0.002]. Orders to withhold reintubation were written sooner in very elderly (vs. elderly) patients [4 (2-8) vs. 7 (4-13) days, p = 0.02]. Very elderly and elderly patients had similar rates of direct extubation [39 (19.3%) vs. 113 (19.3%)], direct tracheostomy [10 (5%) vs. 40 (6.8%)], initial SBT [105 (52%) vs. 302 (51.5%)] and initial successful SBT [84 (80%) vs. 245 (81.1%)]. Very elderly patients experienced similar ICU outcomes (mortality, length of stay, duration of ventilation) but higher hospital mortality [26 (12.9%) vs. 38 (6.5%)]. Direct tracheostomy and initial failed SBT were associated with worse outcomes. Regional differences existed in withholding orders at ICU admission and in withholding and withdrawal orders after ICU admission.

CONCLUSIONS

Very elderly (vs. elderly) patients had more orders to withhold treatments after ICU admission and higher hospital mortality, but similar ICU outcomes and IMV discontinuation. Significant regional differences existed in withholding and withdrawal practices.

Withdrawing or withholding treatments in health care rationing: an interview study on ethical views and implications

Background

When rationing health care, a commonly held view among ethicists is that there is no ethical difference between withdrawing or withholding medical treatments. In reality, this view does not generally seem to be supported by practicians nor in legislation practices, by for example adding a ‘grandfather clause’ when rejecting a new treatment for lacking cost-effectiveness. Due to this discrepancy, our objective was to explore physicians’ and patient organization representatives’ experiences- and perceptions of withdrawing and withholding treatments in rationing situations of relative scarcity.

Methods

Fourteen semi-structured interviews were conducted in Sweden with physicians and patient organization representatives, thematic analysis was used.

Results

Participants commonly express internally inconsistent views regarding if withdrawing or withholding medical treatments should be deemed as ethically equivalent. Participants express that in terms of patients’ need for treatment (e.g., the treatment’s effectiveness and the patient’s medical condition) withholding and withdrawing should be deemed ethically equivalent. However, in terms of prognostic differences, and the patient-physician relation and communication, there is a clear discrepancy which carry a moral significance and ultimately makes withdrawing psychologically difficult for both physicians and patients, and politically difficult for policy makers.

Conclusions

We conclude that the distinction between withdrawing and withholding treatment as unified concepts is a simplification of a more complex situation, where different factors related differently to these two concepts. Following this, possible policy solutions are discussed for how to resolve this experienced moral difference by practitioners and ease withdrawing treatments due to health care rationing. Such solutions could be to have agreements between the physician and patient about potential future treatment withdrawals, to evaluate the treatment’s effect, and to provide guidelines on a national level.

Chasing Certainty After Cardiac Arrest: Can a Technological Innovation Solve a Moral Dilemma?

When information on a coma patient’s expected outcome is uncertain, a moral dilemma arises in clinical practice: if life-sustaining treatment is continued, the patient may survive with unacceptably poor neurological prospects, but if withdrawn a patient who could have recovered may die. Continuous electroencephalogram-monitoring (cEEG) is expected to substantially improve neuroprognostication for patients in coma after cardiac arrest. This raises expectations that decisions whether or not to withdraw will become easier. This paper investigates that expectation, exploring cEEG’s impacts when it becomes part of a socio-technical network in an Intensive Care Unit (ICU). Based on observations in two ICUs in the Netherlands and one in the USA that had cEEG implemented for research, we interviewed 25 family members, healthcare professionals, and surviving patients. The analysis focuses on (a) the way patient outcomes are constructed, (b) the kind of decision support these outcomes provide, and (c) how cEEG affects communication between professionals and relatives. We argue that cEEG can take away or decrease the intensity of the dilemma in some cases, while increasing uncertainty for others. It also raises new concerns. Since its actual impacts furthermore hinge on how cEEG is designed and implemented, we end with recommendations for ensuring responsible development and implementation.

Common medical ethical issues faced by healthcare professionals in KSA

Objective

There are growing concerns about ethical issues in the healthcare system. This study was conducted to determine the nature of common ethical issues faced by healthcare providers in a tertiary-care hospital in KSA.

Method

This cross-sectional study comprised a self-administered questionnaire given to the physicians working at King Abdulaziz Medical City Hospital-Riyadh, Ministry of National Guard Health Affairs (KAMC-RD, MNGHA). We used a convenience sampling technique during symposia and conferences.

Results

We distributed 240 questionnaires amongst the physicians and recorded a response rate of 80%; 68% (136) of the respondents were men, while 82.5% were Saudis. The mean age of the group was 34.08 ± 10.43 years. Only 69% (138) of the physicians had ever received any formal teaching in bioethics. Most physicians (77.5%) demanded clear guidelines to help them to take appropriate ethical decisions on therapeutic futility, whereas 54% felt that they sometimes overtreat their patients.

Conclusion

This study reported a lack of knowledge in certain healthcare-related ethical issues in a significant proportion of the physicians. There is a need for a standard educational agenda for medical ethics for healthcare providers, not only during medical school but also after graduation and during clinical rounds.

Time-Limited Trials in the Intensive Care Unit to Promote Goal-Concordant Patient Care

Consider the hypothetical case of a 75-year-old patient admitted to the intensive care unit (ICU) for acute hypoxic respiratory failure due to pneumonia and systolic heart failure. Although she suffers from a potentially treatable infection, her advanced age and chronic illness increase her risk of experiencing a poor outcome. Her family feels conflicted about whether the use of mechanical ventilation would be acceptable given what they understand about her values and preferences. In the ICU setting, clinicians, patients, and surrogate decision-makers frequently face challenges of prognostic uncertainty as well as uncertainty regarding patients' goals and values. Time-limited trials (TLTs) of life-sustaining treatments in the ICU have been proposed as one strategy to help facilitate goal-concordant care in the midst of a complex and high-stakes decision-making environment. TLTs represent an agreement between clinicians and patients or surrogate decision-makers to employ a therapy for an agreed-upon time period, with a plan for subsequent reassessment of the patient's progress according to previously-established criteria for improvement or decline. Herein, we review the concept of TLTs in intensive care, and explore their potential benefits, barriers, and challenges. Research demonstrates that, in practice, TLTs are conducted infrequently and often incompletely, and are challenged by system-level factors that diminish their effectiveness. The promise of TLTs in intensive care warrants continued research efforts, including implementation studies to improve adoption and fidelity, observational research to determine optimal timeframes for TLTs, and interventional trials to determine if TLTs ultimately improve the delivery of goal-concordant care in the ICU.

Identification of core ethical topics for interprofessional education in the intensive care unit: a thematic analysis

Medical educators have not identified effective approaches for interprofessional ethics education of clinicians who work in intensive care units (ICUs), in spite of the fact that ICUs have a high incidence of ethical conflicts. As a first step in designing an interprofessional ethics education initiative tailored to the needs of ICU team members, we interviewed 12 professionals from the medical and surgical ICUs of a tertiary care academic medical center to understand what they know about medical ethics. Respondents were interviewed between November 2016 and February 2017. We used the 'think aloud' approach and realist thematic analysis of the sessions to evaluate the extent and content of interprofessional team members' knowledge of medical ethics. We found wide variation in their knowledge of and facility in applying the principles and concepts of biomedical ethics and ways of resolving ethical conflicts. Ethics education tailored to these areas will help equip critical care professionals with the necessary knowledge and skills to discuss and address ethical conflicts encountered in the ICU. Preventive ethics rounds are one approach for providing real-time, embedded interprofessional ethics education in the clinical setting.

Withholding and Withdrawal of Treatments: Differences in Perceptions between Intensivists, Oncologists, and Prosecutors in Brazil

Background: Legal concerns have been implicated in the occurrence of variability in decisions of limitations of medical treatment (LOMT) before death. Objective: We aimed to assess differences in perceptions between physicians and prosecutors toward LOMT. Measurements: We sent a survey to intensivists, oncologists, and prosecutors from Brazil, from February 2018 to May 2018. Respondents rated the degree of agreement with withholding or withdrawal of therapies in four different vignettes portraying a patient with terminal lung cancer. We measured the difference in agreement between respondents. Results: There were 748 respondents, with 522 (69.8%) intensivists, 106 (14.2%) oncologists, and 120 (16%) prosecutors. Most respondents agreed with withhold of chemotherapy (95.2%), withhold of mechanical ventilation (MV) (90.2%), and withdrawal of MV (78.4%), but most (75%) disagreed with withdrawal of MV without surrogate's consent. Prosecutors were less likely than intensivists and oncologists to agree with withhold of chemotherapy (95.7% vs. 99.2% vs. 100%, respectively, p < 0.001) and withhold of MV (82.4% vs. 98.3% vs. 97.9%, respectively, p < 0.001), whereas intensivists were more likely to agree with withdrawal of MV than oncologists (87.1% vs. 76.1%, p = 0.002). Moreover, prosecutors were more likely to agree with withholding of active cancer treatment than with withholding of MV [difference (95% confidence interval, CI) = 13.2% (5.2 to 21.6), p = 0.001], whereas physicians were more likely to agree with withholding than with withdrawal of MV [difference (95% CI) = 10.9% (7.8 to 14), p < 0.001]. Conclusions: This study found differences and agreements in perceptions toward LOMT between prosecutors, intensivists, and oncologists, which may inform the discourse aimed at improving end-of-life decisions.

Neonatal nurse practitioner ethics knowledge and attitudes

BACKGROUND

Neonatal nurse practitioners have become the frontline staff exposed to a myriad of ethical issues that arise in the day-to-day environment of the neonatal intensive care unit. However, ethics competency at the time of graduation and after years of practice has not been described.

RESEARCH AIM

To examine the ethics knowledge base of neonatal nurse practitioners as this knowledge relates to decision making in the neonatal intensive care unit and to determine whether this knowledge is reflected in attitudes toward ethical dilemmas in the neonatal intensive care unit.

RESEARCH DESIGN

This was a prospective cohort study that examined decision making at the threshold of viability, life-sustaining therapies for sick neonates, and a ranking of the five most impactful ethical issues.

PARTICIPANTS AND RESEARCH CONTEXT

All 47 neonatal nurse practitioners who had an active license in the State of Mississippi were contacted via e-mail. Surveys were completed online using Survey Monkey software.

ETHICAL CONSIDERATIONS

The study was approved by the University of Mississippi Medical Center Institutional Review Board (IRB; #2015-0189).

FINDINGS

Of the neonatal nurse practitioners who completed the survey, 87.5% stated that their religious practices affected their ethical decision making and 76% felt that decisions regarding life-sustaining treatment for a neonate should not involve consultation with the hospital's legal team or risk management. Only 11% indicated that the consent process involved patient understanding of possible procedures. Participating in the continuation or escalation of care for infants at the threshold of viability was the top ethical issue encountered by neonatal nurse practitioners.

DISCUSSION

Our findings reflect deficiencies in the neonatal nurse practitioner knowledge base concerning ethical decision making, informed consent/permission, and the continuation/escalation of care.

CONCLUSION

In addition to continuing education highlighting ethics concepts, exploring the influence of religion in making decisions and knowing the most prominent dilemmas faced by neonatal nurse practitioners in the neonatal intensive care unit may lead to insights into potential solutions.

Does special education in palliative medicine make a difference in end-of-life decision-making?

Background

Characteristics of the physician influence the essential decision-making in end-of-life care. However, the effect of special education in palliative medicine on different aspects of decision-making in end-of-life care remains unknown. The aim of this study was to explore the decision-making in end-of-life care among physicians with or without special competency in palliative medicine (cPM).

Methods

A questionnaire including an advanced lung cancer patient-scenario with multiple decision options in end-of-life care situation was sent to 1327 Finnish physicians. Decisions to withdraw or withhold ten life-prolonging interventions were asked on a scale from 1 (definitely would not) to 5 (definitely would) – first, without additional information and then after the family’s request for aggressive treatment and the availability of an advance directive. Values from chronological original scenario, family’s appeal and advance directive were clustered by trajectory analysis.

Results

We received 699 (53%) responses. The mean values of the ten answers in the original scenario were 4.1 in physicians with cPM, 3.4 in general practitioners, 3.4 in surgeons, 3.5 in internists and 3.8 in oncologists (p < 0.05 for physicians with cPM vs. oncologists and p < 0.001 for physicians with cPM vs. others). Younger age and not being an oncologist or not having cPM increased aggressive treatment decisions in multivariable logistic regression analysis. The less aggressive approach of physicians with cPM differed between therapies, being most striking concerning intravenous hydration, nasogastric tube and blood transfusions. The aggressive approach increased by the family’s request (p < 0.001) and decreased by an advance directive (p < 0.001) in all physicians, regardless of special education in palliative medicine.

Conclusion

Physicians with special education in palliative medicine make less aggressive decisions in end-of-life care. The impact of specialty on decision-making varies among treatment options. Education in end-of-life care decision-making should be mandatory for young physicians and those in specialty training.

Decreasing Use of Percutaneous Endoscopic Gastrostomy Tube Feeding in Japan

OBJECTIVES

To identify trends in percutaneous endoscopic gastrostomy (PEG) tube placement and intravenous hyperalimentation (IVH) in nonhospital settings (as a potential alternative to tube feeding for nutrition) and to summarize published reports concerning the decision-making process for PEG placement.

DESIGN

National survey and systematic review.

SETTING

Japan.

PARTICIPANTS

All Japanese people.

MEASUREMENTS

Data on numbers of individuals with a PEG tube and IVH were obtained from the website of the Japanese Ministry of Health, Labour, and Welfare and published reports concerning the decision-making process for PEG placement in Japan were summarized.

RESULTS

The number of PEG tube placements peaked in 2007 and has been decreasing since Japan experienced the Great East Japan Earthquake in 2011. A further decline was seen in 2015 after the Japanese Ministry of Health, Labour and Welfare revised the fee schedule in 2014. More than half of individuals who had tubes were aged 80 and older during the years observed. In contrast, the number of individuals receiving IVH was lowest in the same year as PEG tube placement peaked and has been increasing ever since. Four studies reported that the decision-making process included consideration of not only the underlying disease, but also the individual's age and social barriers and the physician's personal philosophy.

CONCLUSION

The number of PEG tube placements has been decreasing since its peak in 2007, and the number of individuals receiving IVH has been increasing. Many factors influence the decision-making process for PEG tube placement. Physicians in Japan may be realizing that there is little evidence to support the use of tube feeding in frail elderly adults.

US Physicians' Opinions about Distinctions between Withdrawing and Withholding Life-Sustaining Treatment

Decisions to withhold or withdraw life-sustaining treatment (LST) precede the majority of ICU deaths. Although professional guidelines generally treat the two as ethically equivalent, evidence suggests withdrawing LST is often more psychologically difficult than withholding it. The aim of the experiment was to investigate whether physicians are more supportive of withholding LST than withdrawing it and to assess how physicians' opinions are shaped by their religious characteristics, specialty, and experience caring for dying patients. In 2010, a survey was mailed to 2016 practicing US physicians. Physicians were asked whether physicians should always comply with a competent patient's request to withdraw LST, whether withdrawing LST is more psychologically difficult than withholding it, and whether withdrawing LST is typically more ethically problematic than withholding it. Of 1880 eligible physicians, 1156 responded to the survey (62%); 93% agreed that physicians should always comply with a competent patient's request to withdraw LST. More than half of the physicians reported that they find withdrawing LST more psychologically difficult than withholding it (61%), and that withdrawing LST is typically more ethically problematic (59%). Physician religiosity was associated with finding withdrawal more ethically problematic, but not with finding it more psychologically difficult. Physicians working in an end-of-life specialty and physicians with more experience caring for dying patients were less likely to endorse either a psychological or an ethical distinction between withdrawing and withholding LST. Most US physicians find withdrawing LST not only more psychologically difficult, but also more ethically problematic than withholding such treatment. Physicians' opinions are to some extent shaped by their religious characteristics, specialty, and levels of experience caring for dying patients.

Guidelines for the withdrawal of life-sustaining measures

BACKGROUND

Withdrawal of life-sustaining measures is a common event in the intensive care unit yet it involves a complex balance of medical, legal and ethical considerations. Very few healthcare providers have been specifically trained to withdraw life-sustaining measures, and no comprehensive guidelines exist to help ensure clinicians deliver the highest quality of care to patients and families. Hence, we sought to develop guidelines for the process of withdrawing life-sustaining measures in the clinical setting.

METHODS

We convened an interdisciplinary group of ICU care providers from the Canadian Critical Care Society and the Canadian Association of Critical Care Nurses, and used a modified Delphi process to answer key clinical and ethical questions identified in the literature.

RESULTS

A total of 39 experienced clinicians completed the initial workshop, and 36 were involved in the subsequent Delphi rounds. The group developed a series of guidelines to address (1) preparing for withdrawal of life-sustaining measures; (2) assessment of distress; (3) pharmaceutical management of distress; and (4) discontinuation of life-sustaining measures and monitoring. The group achieved consensus on all aspects of the guidelines after the third Delphi round.

CONCLUSION

We present these guidelines to help physicians provide high-quality end of life (EOL) care in the ICU. Future studies should address their effectiveness from both critical care team and family perspectives.

Old age and forgoing treatment: a nationwide mortality follow-back study in the Netherlands

BACKGROUND

The ageing of the population raises the need to study forgoing treatment decisions among older people.

AIM

To describe the incidence and decision-making of forgoing treatment and identify age-related differences.

METHODS

A nationwide study of a stratified sample from the Statistics Netherlands death registry to which all deaths were reported in 2010. All attending physicians of those deaths received a questionnaire about end-of-life decisions. 6600 cases were studied. We examined three age groups: 17-64, 65-79, and 80 and above. Logistic regression analyses were performed to identify age-related differences controlling for other patient characteristics.

RESULTS

Forgoing treatment occurred in 37% of the total population, with a significant increase in the incidence across age. The most common treatments withheld/withdrawn were artificial hydration/nutrition, medication and antibiotics. Age-related differences were found, especially for withholding artificial hydration/nutrition among patients aged 65-79 (OR 2.04), and for withdrawing medication (OR 2.51) and antibiotics (OR 2.10) among the oldest when compared to the youngest patients. The most common reason for making the decision was 'no chance of improvement'. The likelihood of forgoing treatment due to 'loss of dignity' was higher for the oldest (OR 2.32), as well as due to the request/wish of the patient (OR 1.97), when compared to the youngest patients.

CONCLUSIONS

Forgoing treatment occurred in a substantial proportion of older people, and more often than in younger age groups. The avoidance of burdensome treatment solely to prolong life suggests a better acceptance that these patients are nearing death.

The Durban World Congress Ethics Round Table Conference Report: I. Differences between withholding and withdrawing life-sustaining treatments

INTRODUCTION

Withholding life-sustaining treatments (WHLST) and withdrawing life-sustaining treatments (WDLST) occur in most intensive care units (ICUs) around the world to varying degrees.

METHODS

Speakers from invited faculty of the World Federation of Societies of Intensive and Critical Care Medicine Congress in 2013 with an interest in ethics were approached to participate in an ethics round table. Participants were asked if they agreed with the statement "There is no moral difference between withholding and withdrawing a mechanical ventilator." Differences between WHLST and WDLST were discussed. Official statements relating to WHLST and WDLST from intensive care societies, professional bodies, and government statements were sourced, documented, and compared.

RESULTS

Sixteen respondents stated that there was no moral difference between withholding or withdrawing a mechanical ventilator, 2 were neutral, and 4 stated that there was a difference. Most ethicists and medical organizations state that there is no moral difference between WHLST and WDLST. A review of guidelines noted that all but 1 of 29 considered WHLST and WDLST as ethically or legally equivalent.

CONCLUSIONS

Most respondents, practicing intensivists, stated that there is no difference between WHLST and WDLST, supporting most ethicists and professional organizations. A minority of physicians still do not accept their equivalency.

Neonatal hypoxic-ischaemic encephalopathy: most deaths followed end-of-life decisions within three days of birth

AIM

To investigate the circumstances surrounding end-of life decisions (EoL) of infants with hypoxic-ischaemic encephalopathy (HIE) and examine changes over a 10-year period.

METHODS

Retrospective chart review of all infants with HIE who died during 2000-2004 and 2005-2009 in a Level III Neonatal Intensive Care Unit in Madrid, Spain.

RESULTS

Of 70 infants with HIE, 18 died during the neonatal period. The mean age of death was 64.4 ± 51 h. In 17 of the 18 infants (94%), death was preceded by an EoL decision, four after withholding therapy (WH) and 13 after withdrawal therapy (WDT). All infants with WH were previously stable and without respiratory support, while all 13 infants in the WDT group had respiratory support and three were unstable. The age of death was greater in the WH group than the WDT group (122 ± 63 h vs 50 ± 34; p < 0.001). After the EoL decision, 11 (65%) infants received sedatives. There were no differences between the time periods.

CONCLUSION

In our cohort, most deaths in newborns with HIE were preceded by EoL decisions mainly within the first 3 days after birth. We did not find changes over the first decade of the 21st century, and death was mainly determined by WDT.

Withdrawal of life-sustaining treatment in a mixed intensive care unit: most common in patients with catastropic brain injury

OBJECTIVE

To determine the incidence of withdrawal of life-sustaining treatment in various groups of patients in a mixed intensive care unit (ICU).

DESIGN

Observational retrospective.

SETTING

University hospital mixed medical, neurological, neurosurgical and surgical ICU.

PATIENTS

All patients admitted to the ICU between 1 November 2006, and 31 October 2007.

RESULTS

1,353 Patients were admitted to our ICU between 1 November 2006, and 31 October 2007. During this period, 218 (16.1%) patients died in the ICU, 10 of which were excluded for further analysis. In 174 (83.7%) of the remaining 208 patients, life-sustaining treatment was withdrawn. Severe CNS injury was in 86 patients (49.4%) being the reason for withdrawal of treatment, followed by MODS in 67 patients (38.5%). Notably, treatment was withdrawn in almost all patients (95%) who died of CNS failure. Patients who died in the ICU were significantly older, more often admitted for medical than surgical reasons, and had higher SOFA and APACHE II scores compared with those who survived their ICU stay. Also, SOFA scores before discharge/death were significantly different from admission scores. Of the 1,135 patients who survived their ICU stay, only 51 patients (4.5%) died within 28 days after ICU discharge.

CONCLUSIONS

In 83, 7% of patients who die in the mixed ICU life-sustaining treatment is withdrawn. Severe cerebral damage was the leading reason to withdraw life-sustaining treatment.

Ethical challenges with deactivation of durable mechanical circulatory support at the end of life: left ventricular assist devices and total artificial hearts

Left ventricular assist devices (LVADs) and total artificial hearts (TAHs) are surgically implanted as permanent treatment of unrecoverable heart failure. Both LVADs and TAHs are durable mechanical circulatory support (MCS) devices that can prolong patient survival but also alter end-of-life trajectory. The permissibility of discontinuing assisted circulation is controversial because device deactivation is a life-ending intervention. Durable MCS is intended to successfully replace native physiological functions in heart disease. We posit that the presence of new lethal pathophysiology (ie, a self-perpetuating cascade of abnormal physiological processes causing death) is a central element in evaluating the permissibility of deactivating an LVAD or a TAH. Consensual discontinuation of durable MCS is equivalent with allowing natural death when there is an onset of new lethal pathophysiology that is unrelated to the physiological functions replaced by an LVAD or a TAH. Examples of such lethal conditions include irreversible coma, circulatory shock, overwhelming infections, multiple organ failure, refractory hypoxia, or catastrophic device failure. In all other situations, deactivating the LVAD/TAH is itself the lethal pathophysiology and the proximate cause of death. We postulate that the onset of new lethal pathophysiology is the determinant factor in judging the permissibility of the life-ending discontinuation of a durable MCS.

Medical ethical knowledge and moral attitudes among physicians in Bavaria

BACKGROUND

Everyday clinical practice requires knowledge of medical ethics and the taking of moral positions. We investigated the ethical knowledge and attitudes of a representative sample of physicians with regard to end-of-life decisions, euthanasia, and the physician-patient relationship.

METHODS

192 physicians (96 women, 96 men; mean age 50) in a random sample of Bavarian physicians completed our structured questionnaire. Data were collected from September to November 2010.

RESULTS

There was much uncertainty among the respondents about the relevant knowledge for end-of-life decisions and the implementation of existing guidelines and laws on euthanasia and advance directives. Attitudes to ethical questions were found to be correlated with the length of time the physicians had been in practice.

CONCLUSION

Physicians' personal values and moral attitudes play a major role in clinical decision-making. We used a questionnaire to examine physicians' opinions about end-of-life issues and to determine the factors that might influence them. We found their knowledge of medical ethics to be inadequate. Competence in medical ethics needs to be strengthened by more ethical teaching in medical school, specialty training, and continuing medical education.

The process of end-of-life decision-making in pediatrics: a national survey in the Netherlands

OBJECTIVE

The goal of this study was to investigate how Dutch pediatric specialists reach end-of-life decisions, how they involve parents, and how they address conflicts.

METHODS

We conducted a national cross-sectional survey among pediatric intensivists, oncologists, neurologists, neurosurgeons, and metabolic pediatricians practicing in the 8 Dutch university hospitals. We collected information on respondents' overall opinions and their clinical practice.

RESULTS

Of the 185 eligible pediatric specialists, 74% returned the questionnaire. All responding physicians generally discuss an end-of-life decision with colleagues before discussing it with parents. In half of the reported cases, respondents informed parents about the intended decision and asked their permission. In one-quarter of the cases, respondents informed parents without asking for their permission. In the remaining one-quarter of the cases, respondents advised parents and consequently allowed them to have the decisive voice. The chosen approach is highly influenced by type of decision and type and duration of treatment. Conflicts within medical teams arose as a result of uncertainties about prognosis and treatment options. Most conflicts with parents arose because parents had a more positive view of the prognosis or had religious objections to treatment discontinuation. All conflicts were eventually resolved by a combination of strategies. In 66% of all cases, pain and symptom management were intensified before the child's death.

CONCLUSIONS

Within Dutch pediatrics, end-of-life decisions are team decisions. Pediatric specialists differ considerably in how they involve parents in end-of-life decision-making, ranging from benevolent paternalism to parental autonomy. Main conflict-solving strategies are taking more time and extending discussions.

Ethics and end-of-life care for adults in the intensive care unit

The intensive care unit (ICU) is where patients are given some of the most technologically advanced life-sustaining treatments, and where difficult decisions are made about the usefulness of such treatments. The substantial regional variability in these ethical decisions is a result of many factors, including religious and cultural beliefs. Because most critically ill patients lack the capacity to make decisions, family and other individuals often act as the surrogate decision makers, and in many regions communication between the clinician and family is central to decision making in the ICU. Elsewhere, involvement of the family is reduced and that of the physicians is increased. End-of-life care is associated with increased burnout and distress among clinicians working in the ICU. Since many deaths in the ICU are preceded by a decision to withhold or withdraw life support, high-quality decision making and end-of-life care are essential in all regions, and can improve patient and family outcomes, and also retention of clinicians working in the ICU. To make such a decision requires adequate training, good communication between the clinician and family, and the collaboration of a well functioning interdisciplinary team.

Physicians' psychosocial barriers to different modes of withdrawal of life support in critical care: A qualitative study in Japan

Despite a number of guidelines issued in Anglo-American countries over the past few decades for forgoing treatment stating that there is no ethically relevant difference between withholding and withdrawing life-sustaining treatments (LST), it is recognized that many healthcare professionals in Japan as well as some of their western counterparts do not agree with this statement. This research was conducted to investigate the barriers that prevent physicians from withdrawing specific LST in critical care settings, focusing mainly on the modes of withdrawal of LST, in what the authors believe was the first study of its kind anywhere in the world. In 2006-2007, in-depth, face-to-face, semistructured interviews were conducted with 35 physicians working at emergency and critical care facilities across Japan. We elicited their experiences, attitudes, and perceptions regarding withdrawal of mechanical ventilation and other LST. The process of data analysis followed the grounded theory approach. We found that the psychosocial resistance of physicians to withdrawal of artificial devices varied according to the modes of withdrawal, showing a strong resistance to withdrawal of mechanical ventilation that requires physicians to halt the treatment when continuation of its mechanical operation is possible. However, there was little resistance to the withdrawal of percutaneous cardiopulmonary support and artificial liver support when their continuation was mechanically or physiologically impossible. The physicians shared a desire for a "soft landing" of the patient, that is, a slow and gradual death without drastic and immediate changes, which serves the psychosocial needs of the people surrounding the patient. For that purpose, vasopressors were often withheld and withdrawn. The findings suggest what the Japanese physicians avoid is not what they call a life-shortening act but an act that would not lead to a soft landing, or a slow death that looks 'natural' in the eyes of those surrounding the patient. The purpose of constructing such a final scene is believed to fulfill the psychosocial needs of the patient's family and the physicians, who emphasize on how death feels to those surrounding the patient. Unless withdrawing LST would lead to a soft landing, Japanese clinicians, who recognize that the results of withdrawing LST affect not only the patient but those around the patient, are likely to feel that there is an ethically relevant difference between withholding and withdrawing LST.

Deciding in the dark: advance directives and continuation of treatment in chronic critical illness

OBJECTIVE

Chronic critical illness is a devastating syndrome for which treatment offers limited clinical benefit but imposes heavy burdens on patients, families, clinicians, and the health care system. We studied the availability of advance directives and appropriate surrogates to guide decisions about life-sustaining treatment for the chronically critically ill and the extent and timing of treatment limitation.

DESIGN

Prospective cohort study.

SETTING

Respiratory Care Unit (RCU) in a large, tertiary, urban, university-affiliated, hospital.

PATIENTS

Two hundred three chronically critically ill adults transferred to RCU after tracheotomy for failure to wean from mechanical ventilation in the intensive care unit.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We interviewed RCU caregivers and reviewed patient records to identify proxy appointments, living wills, or oral statements of treatment preferences, resuscitation directives, and withholding/withdrawal of mechanical ventilation, nutrition, hydration, renal replacement and vasopressors. Forty-three of 203 patients (21.2%) appointed a proxy and 33 (16.2%) expressed preferences in advance directives. Do not resuscitate directives were given for 71 patients (35.0%). Treatment was limited for 39 patients (19.2%). Variables significantly associated with treatment limitation were proxy appointment prior to study entry (time of tracheotomy/RCU transfer) (odds ratio = 6.7, 95% confidence interval [CI], 2.3-20.0, p = 0.0006) and palliative care consultation in the RCU (OR = 40.9, 95% CI, 13.1-127.4, p < 0.0001). Median (interquartile range) time to first treatment limitation was 39 (31.0-45.0) days after hospital admission and 13 (8.0-29.0) days after RCU admission. For patients dying after treatment limitation, median time from first limitation to death ranged from 3 days for mechanical ventilation and hydration to 7 days for renal replacement.

CONCLUSIONS

Most chronically critically ill patients fail to designate a surrogate decision-maker or express preferences regarding life-sustaining treatments. Despite burdensome symptoms and poor outcomes, limitation of such treatments was rare and occurred late, when patients were near death. Opportunities exist to improve communication and decision-making in chronic critical illness.

Do-not-resuscitate orders in the critically ill patient--an observational study with special emphasis on withholding of renal replacement therapy

We examined the process, consequences and impact of writing a Do-Not-Resuscitate (DNR) order in a cohort of critically-ill ICU patients. Special emphasis was given to the DNR order including withholding renal replacement therapy. A DNR code was mainly written in the first week following ICU admission and more often given to medical, older and sicker patients. Patients never actively participated in the decision and in only half of the cases the DNR order was discussed with relatives. Mortality of all patients studied was 21% of whom 67% died with a DNR order. In our population, the final in-hospital mortality rate of DNR-coded patients was 100%, because the DNR status was ordered when the patients were already very sick. DNR-coded patients died after a longer mean length of ICU stay than patients without a code. Withholding renal replacement therapy was commonly added to the DNR order even if renal failure either was not present or never developed.

Withdrawing may be preferable to withholding

The majority of deaths on the intensive care unit now occur following a decision to limit life-sustaining therapy, and end-of-life decision making is an accepted and important part of modern intensive care medical practice. Such decisions can essentially take one of two forms: withdrawing – the removal of a therapy that has been started in an attempt to sustain life but is not, or is no longer, effective – and withholding – the decision not to make further therapeutic interventions. Despite wide agreement by Western ethicists that there is no ethical difference between these two approaches, these issues continue to generate considerable debate. In this article, I will provide arguments why, although the two actions are indeed ethically equivalent, withdrawing life-sustaining therapy may in fact be preferable to withholding.
