Worldwide similarities and differences in the foregoing of life-sustaining treatments

The Complex Dynamics of Decision-Making at the End of Life in the Intensive Care Unit: A Systematic Review of Stakeholders' Views and Influential Factors

A lack of consensus resulting in severe conflicts is often observed between the stakeholders regarding their respective roles in end-of-life (EOL) decision-making in the ICU. Since the burden of these decisions lies upon the individuals, their opinions must be known by medical, judicial, legislative, and governmental authorities. Part of the solution to the issues that arise would be to examine and understand the views of the people in different societies. Hence, in this systematic review, we assessed the attitudes of the physicians, nurses, families, and the general public toward who should be involved in decision-making and influencing factors. Toward this, we searched three electronic databases, i.e., PubMed, CINAHL (Cumulative Index to Nursing & Allied Health), and Embase. A matrix was developed, discussed, accepted, and used for data extraction by two independent investigators. Study quality was evaluated using the Newcastle-Ottawa Scale. Data were extracted by one researcher and double-checked by a second one, and any discrepancies were discussed with a third researcher. The data were analyzed descriptively and synthesized according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Thirty-three studies met our inclusion criteria. Most involved healthcare professionals and reported geographic variations in different timeframes. While paternalistic features have been observed, physicians overall showed an inclination toward collaborative decision-making. Correspondingly, the nursing staff, families, and the public are aligned toward patient and relatives' participation, with nurses expressing their own involvement as well. Six categories of influencing factors were identified, with high-impact factors, including demographics, fear of litigation, and regulation-related ones. Findings delineate three key points. Firstly, overall stakeholders' perspectives toward EOL decision-making in the ICU seem to be leaning toward a more collaborative decision-making direction. Secondly, to reduce conflicts and reach a consensus, multifaceted efforts are needed by both healthcare professionals and governmental/regulatory authorities. Finally, due to the multifactorial complexity of the subject, directly related to demographic and regulatory factors, these efforts should be more extensively sought at a regional level.

End-of-Life Issues in Intensive Care Units

Critical care clinicians strive to reverse the disease process and are frequently faced with difficult end-of-life (EoL) situations, which include transitions from curative to palliative care, avoidance of disproportionate care, withholding or withdrawing therapy, responding to advance treatment directives, as well as requests for assistance in dying. This article presents a summary of the most common issues encountered by intensivists caring for patients around the end of their life. Topics explored are the practices around limitations of life-sustaining treatment, with specific mention to the thorny subject of assisted dying and euthanasia, as well as the difficulties encountered regarding the adoption of advance care directives in clinical practice and the importance of integrating palliative care in the everyday practice of critical-care physicians. The aim of this article is to enhance understanding around the complexity of EoL decisions, highlight the intricate cultural, religious, and social dimensions around death and dying, and identify areas of potential improvement for individual practice.

Implication of the Life-Sustaining Treatment Decisions Act on End-of-Life Care for Korean Terminal Patients

Purpose

Life-sustaining treatment (LST) decisions for patients and caregivers at the end-of-life (EOL) process are supported by the “Act on Hospice and Palliative Care and Decisions on LST for Patients at the EOL,” enforced in February 2018. It remains unclear whether the act changes EOL decisions and LST implementation in clinical practice. For this study, we investigated patients’ decision-making regarding LSTs during the EOL process since the act’s enforcement.

Materials and Methods

Retrospective reviews were conducted on adult patients who were able to decide to terminate LST and died at Seoul National University Hospital between February 5, 2018, and February 5, 2019. We examined demographics, who made the decisions, the type and date of documentation confirming patient's LST, and whether the LST was withheld or withdrawn.

Results

Of 809 patients who were enrolled, 29% (n=231) completed forms regarding LST themselves, and 71% (n=578) needed family members to decide. The median time from confirmation of the EOL process to death and from the Advance Statement to death were 2 and 5 days, respectively (both ranges, 0 to 244). In total, 90% (n=727) of patients withheld treatment, and 10% (n=82)withdrew it. We found a higher withdrawal rate when family members made the decisions (13.3% vs. 1.7%, p < 0.001).

Conclusion

After the act’s enforcement, withdrawing LSTs became lawful and self-determination rates increased. Family members still make 71% of decisions regarding LSTs, but these are often inconsistent with the patients’ wishes; thus, further efforts are needed to integrate the new act into clinical practice.

Teaching End-of-Life Communication in Intensive Care Medicine: Review of the Existing Literature and Implications for Future Curricula

OBJECTIVES:

End-of-life (EOL) situations are common in the intensive care unit (ICU). Poor communication in respective situations may result in conflict and/or post-traumatic stress disorder in patients' next of kin. Thus, training for EOL communication seems pivotal. Primary objective of the current report was to identify approaches for educational programs in the ICU with regard to EOL communication as well as to conclude on implications for future curricula.

MATERIALS AND METHODS:

A literature review in MEDLINE, EMBASE, and PsychINFO was performed. A total of 3484 articles published between 2000 until 2016 were assessed for eligibility. Nine articles reporting on education in EOL communication in the ICU were identified and analyzed further.

RESULTS:

The duration of EOL workshops ranged from 3 hours to 3 days, with several different educational methods being applied. Mounting data suggest improved comfort, preparedness, and communication performance in EOL providers following specific EOL training. Due to missing data, the effect of EOL training programs on respective patients' next of kin remains unclear.

CONCLUSION:

Few scientific investigations focus on EOL communication in intensive care medicine. The available evidence points to increased comfort and EOL communication performance following specific individual EOL training. Given the general importance of EOL communication, we suggest implementation of educational EOL programs. When developing future educational programs, educators should consider previous experience of participants, clearly defined objectives based on institutional needs, and critical care society recommendations to ensure best benefit of all involved parties.

Evolution and prognosis of long intensive care unit stay patients suffering a deterioration: A multicenter study

PURPOSE

The prognosis of a patient who deteriorates during a prolonged intensive care unit (ICU) stay is difficult to predict. We analyze the prognostic value of the serialized Sequential Organ Failure Assessment (SOFA) score and other variables in the early days after a complication and to build a new predictive score.

MATERIALS AND METHODS

EPIPUSE (Evolución y pronóstico de los pacientes con ingreso prolongado en UCI que sufren un empeoramiento, Evolution and prognosis of long intensive care unit stay patients suffering a deterioration) study is a prospective, observational study during a 3-month recruitment period in 75 Spanish ICUs. We focused on patients admitted in the ICU for 7 days or more with complications of adverse events that involve organ dysfunction impairment. Demographics, clinical variables, and serialized SOFA after a supervening clinical deterioration were recorded. Univariate and multivariate analyses were performed, and a predictive model was created with the most discriminating variables.

RESULTS

We included 589 patients who experienced 777 cases of severe complication or adverse event. The entire sample was randomly divided into 2 subsamples, one for development purposes (528 cases) and the other for validation (249 cases). The predictive model maximizing specificity is calculated by minimum SOFA + 2 * cardiovascular risk factors + 2 * history of any oncologic disease or immunosuppressive treatment + 3 * dependence for basic activities of daily living. The area under the receiver operating characteristic curve is 0.82. A 14-point cutoff has a positive predictive value of 100% (92.7%-100%) and negative predictive value of 51% (46.4%-55.5%) for death.

CONCLUSIONS

EPIPUSE model can predict mortality with a specificity and positive predictive value of 99% in some groups of patients.

Limitation of life-sustaining treatment in patients with prolonged admission to the ICU. Current situation in Spain as seen from the EPIPUSE Study

OBJECTIVE

Limitation of life-sustaining treatment (LLST) is a recommended practice in certain circumstances. Limitation practices are varied, and their application differs from one center to another. The present study evaluates the current situation of LLST practices in patients with prolonged admission to the ICU who suffer worsening of their condition.

DESIGN

A prospective, observational cohort study was carried out.

SETTING

Seventy-five Spanish ICUs.

PATIENTS

A total of 589 patients suffering 777 complications or adverse events with organ function impairment after day 7 of admission, during a three-month recruitment period.

MAIN VARIABLES OF INTEREST

The timing of limitation, the subject proposing LLST, the degree of agreement within the team, the influence of LLST upon the doctor-patient-family relationship, and the way in which LLST is implemented.

RESULTS

LLST was proposed in 34.3% of the patients presenting prolonged admission to the ICU with severe complications. The incidence was higher in patients with moderate to severe lung disease, cancer, immunosuppressive treatment or dependence for basic activities of daily living. LLST was finally implemented in 97% of the cases in which it was proposed. The decision within the medical team was unanimous in 87.9% of the cases. The doctor-patient-family relationship usually does not change or even improves in this situation.

CONCLUSION

LLST in ICUs is usually carried out under unanimous decision of the medical team, is performed more frequently in patients with severe comorbidity, and usually does not have a negative impact upon the relationship with the patients and their families.

Does regional variation impact decision-making in the management and palliation of pancreatic head adenocarcinoma? Results from an international survey

BACKGROUND

Management and palliation of pancreatic head adenocarcinoma is challenging. End-of-life decision-making is a variable process involving multiple factors.

METHODS

We conducted a qualitative, physician-based, 40-question international survey characterizing the impact of medical, religious, social, training and system factors on care.

RESULTS

A total of 258 international clinicians completed the survey. Respondents were typically fellowship-trained (78%), with a mean of 16 years' experience in a university-affiliated (93%) hepato-pancreato-biliary group (96%) practice. Most (91%) believed resection is potentially curative. Most patients were discussed preoperatively by multidisciplinary teams (94%) and medical assessment clinics (68%), but rarely critical care (21%). Intraoperative surgical palliation included double bypass or no intervention for locally advanced nonresectable tumours (41% and 49% v. 14% and 85%, respectively, for patients with hepatic metastases). Postoperative admission to the intensive care unit was frequent (58%). Severe postoperative complications were often treated with aggressive cardiopulmonary resuscitation, intubation and critical care (96%), with no defined time points for futility (74%). Admitting surgeons guided most end-of-life decisions (97%). Formal medical futility laws were rarely available (26%). Insurance status did not alter treatment (97%) or palliation (95%) in non-universal care regions. Clinician experience, regional culture and training background impacted treatment (all p < 0.05).

CONCLUSION

Despite remarkable overall agreement, geographic and training differences are evident in the treatment and palliation of pancreatic head adenocarcinoma.

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.

End-of-Life Practices in the Intensive Care Unit: The Importance of Geography, Religion, Religious Affiliation, and Culture

End-of-life decisions are made daily in intensive care units worldwide. There are numerous factors affecting these decisions, including geographical location as well as religion and attitudes of caregivers, patients, and families. There is a spectrum of end-of-life care options from full continued care, withholding treatment, withdrawing treatment, and active life-ending procedures.

Impact of an intensive communication strategy on end-of-life practices in the intensive care unit

PURPOSE

Since the 2005 French law on end of life and patients' rights, it is unclear whether practices have evolved. We investigated whether an intensive communication strategy based on this law would influence practices in terms of withholding and withdrawing treatment (WWT), and outcome of patients hospitalised in intensive care (ICU).

METHODS

This was a single-centre, two-period study performed before and after the 2005 law. Between these periods, an intensive strategy for communication was developed and implemented, comprising regular meetings and modalities for WWT. We examined medical records of all patients who died in the ICU or in hospital during both periods.

RESULTS

In total, out of 2,478 patients admitted in period 1, 678 (27%) died in the ICU and 823/2,940 (28%) in period 2. In period 1, among patients who died in the ICU, 45% died subsequent to a decision to WWT versus 85% in period 2 (p < 0.01). Among these, median time delay between ICU admission and initiation of decision-making process was significantly different (6-7 days in period 1 vs. 3-5 days in period 2, p < 0.05). Similarly, median time from admission to actual WWT decision was significantly shorter in period 2 (11-13 days in period 1 vs. 4-6 days in period 2, p < 0.05). Finally, median time from admission to death in the ICU subsequent to a decision to WWT was 13-15 days in period 1 versus 7-8 days in period 2, p < 0.05. Reasons for WWT were not significantly different between periods.

CONCLUSION

Intensive communication brings about quicker end-of-life decision-making in the ICU. The new law has the advantage of providing a legal framework.

The impact of country and culture on end-of-life care for injured patients: results from an international survey

BACKGROUND

Up to 20% of all trauma patients admitted to an intensive care unit die from their injuries. End-of-life decision making is a variable process that involves prognosis, predicted functional outcomes, personal beliefs, institutional resources, societal norms, and clinician experience. The goal of this study was to better understand end-of-life processes after major injury by comparing clinician viewpoints from various countries and cultures.

METHODS

A clinician-based, 38-question international survey was used to characterize the impacts of medical, religious, social, and system factors on end-of-life care after trauma.

RESULTS

A total of 419 clinicians from the United States (49%), Canada (19%), South Africa (11%), Europe (9%), Asia (8%), and Australasia (4%) completed the survey. In America, the admitting surgeon guided most end-of-life decisions (51%), when compared with all other countries (0-27%). The practice structure of American respondents also varied from other regions. Formal medical futility laws are rarely available (14-38%). Ethical consultation services are often accessible (29-98%), but rarely used (0-29%), and typically unhelpful (<30%). End-of-life decision making for patients with traumatic brain injuries varied extensively across regions with regard to the impact of patient age, Glasgow Coma Scale score, and clinician philosophy. Similar differences were observed for spinal cord injuries (age and functional level). The availability and use of "donation after cardiac death" also varied substantially between countries.

CONCLUSIONS

In this unique study, geographic differences in religion, practice composition, decision-maker viewpoint, and institutional resources resulted in significant variation in end-of-life care after injury. These disparities reflect competing concepts (patient autonomy, distributive justice, and religion).

Retrospective agreement and consent to neurocritical care is influenced by functional outcome

INTRODUCTION

Only limited data are available on consent and satisfaction of patients receiving specialized neurocritical care. In this study we (i) analyzed the extent of retrospective consent to neurocritical care--given by patients or their relatives--depending on functional outcome one year after hospital stay, and (ii) identified predisposing factors for retrospective agreement to neurocritical care.

METHODS

We investigated 704 consecutive patients admitted to a nonsurgical neurocritical care unit over a period of 2 years (2006 through 2007). Demographic and clinical parameters were analyzed, and the patients were grouped according to their diagnosis. Functional outcome, retrospective consent to neurocritical care, and satisfaction with hospital stay was obtained by mailed standardized questionnaires. Logistic regression analyses were calculated to determine independent predictors for consent.

RESULTS

High consent and satisfaction after neurointensive care (91% and 90%, respectively) was observed by those patients who reached an independent life one year after neurointensive care unit (ICU) stay. However, only 19% of surviving patients who were functionally dependent retrospectively agreed to neurocritical care. Unfavorable functional outcome and the diagnosis of stroke were independent predictors for missing retrospective consent.

CONCLUSIONS

Retrospective agreement to neurocritical care is influenced by functional outcome. Especially in severely affected stroke patients who cannot communicate their preferences regarding life-sustaining therapy, neurocritical care physicians should balance the expected burdens and benefits of treatment to meet the patients' putative wishes. Efforts should be undertaken to identify predictors for severe disability after neurocritical care.

Intercontinental differences in end-of-life attitudes in the pediatric intensive care unit: results of a worldwide survey

OBJECTIVE

To examine intercontinental differences in end-of-life practices in pediatric intensive care units.

DESIGN

An international survey. The on-line questionnaire consisted of two case scenarios with five questions each. The scenarios described the management of children in pediatric intensive care units and the questions dealt with the decision-making process and the modalities of forgoing life support.

SETTING

The participants at the 5th World Congress on Pediatric Critical Care Medicine organized by the World Federation of Pediatric Intensive and Critical Care Societies (June 2007, Geneva, Switzerland) were invited to participate.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Six hundred sixty seven complete questionnaires were received from 71 countries, which were grouped into six continents: Europe (52.7%), North America (17.9%) and South America (9.5%), Asia (7.6%), Australia (6%), and Middle East (4.3%). In both scenarios, physicians played the major role in decision making in all of the continents. However, parents from North America, Australia, the Middle East, and Asia seem to be more involved in the decision-making process, compared with those from Europe and South America. In cases of septic shock, caregivers from Europe and South America are more prone to forego life support despite parents' wishes. In North America and Australia, parents' presence during cardiopulmonary resuscitation is usually accepted (89.7% and 92.3%, respectively), whereas their presence is less accepted in Asia (54%) and Europe (54.8%), or much less accepted in South America (25.8%) and the Middle East (7.1%). In both scenarios, the option to withhold rather than withdraw life supports was more commonly chosen among all continents, except South America, where the withdrawal of life support was more often proposed (51.6% vs. 45.2%).

CONCLUSIONS

This study confirms that important intercontinental differences exist toward end-of-life issues in pediatric intensive care. Although the legal and ethical situation is rapidly evolving, a certain degree of paternalism seems to persist among European and South-American caregivers. This study suggests that ethical principles depend on the cultural roots of countries or continents, emphasizing the need to foster dialogue on end-of-life issues around the world to learn from each other and improve end-of-life care in pediatric intensive care units.

Changes in medical students' attitudes towards end-of-life decisions across different years of medical training

BACKGROUND

Decisions to forgo life-sustaining medical treatments in terminally ill patients are challenging, but ones that all doctors must face. Few studies have evaluated the impact of medical training on medical students' attitudes towards end-of-life decisions and none have compared them with an age-matched group of non-medical students.

OBJECTIVE

To assess the effect of medical education on medical students' attitudes towards end-of-life decisions in acutely ill patients.

DESIGN

Cross-sectional study.

PARTICIPANTS

Four hundred and two students at The Chinese University of Hong Kong.

MEASUREMENTS

Completion of a questionnaire focused on end-of-life decisions.

MAIN RESULTS

The number of students who felt that cardiopulmonary resuscitation must always be provided was higher in non-medical students (76/90 (84%)) and medical students with less training (67/84 (80%) in year 1 vs. 18/67 (27%) in year 5) (p < 0.001). Discontinuing life-support therapy was more accepted among senior medical students compared to junior medical and non-medical students (27/66 (41%) in year 5 vs. 18/83 (22%) in year 1 and 20/90 (22%) in non-medical students) (p = 0.003). An unexpectedly large proportion of non-medical students (57/89 (64%)) and year 1 medical students (42/84 (50%)) found it acceptable to administer fatal doses of drugs to patients with limited prognosis. Euthanasia was less accepted with more years of training (p < 0.001). When making decisions regarding limitation of life-support therapy, students chose to involve patients (98%), doctors (92%) and families (73%) but few chose to involve nurses (38%).

CONCLUSIONS

Medical students' attitudes towards end-of-life decisions changed during medical training and differed significantly from those of non-medical students.

Bioethical aspects of end-of-life care

Managing end-of-life care can be difficult because of the particular nature of intensive care support, which can separate the biological and the biographical aspects of life. Artificial organ support can temporarily delay death but, at the same time, may fail to restore a quality of life that the patient judges acceptable. For this reason, two concepts must be considered: that the mission of the healthcare system should be to care for patients according to their interests and wishes and that quality of care is related above all to the careful commitment of healthcare workers to the patient's best interests. Keeping these concepts in mind, the rule of the five Cs (competence, collegiality, communication, continuity of care and compassion) might be helpful in the management of end-of-life care. Unfortunately, neither the rule of the five Cs nor the careful use of moral principles in order to promote the patients' dignity can assure a universally acceptable decision. A reasonable level of 'moral certainty', however, might be achieved using a deliberative approach, which provides for the inclusion of all the different subjects involved in the decision-making process (patient, family, doctors, nurses and other carers), in order to reach the best possible decision in a specific situation.

Forgoing life-sustaining or death-prolonging therapy in the pediatric ICU

Most deaths in the pediatric intensive care unit occur after a decision to withhold or withdraw life-sustaining treatments. The management of children at the end of life can be divided into three steps. The first concerns the decision-making process. The second concerns the actions taken once a decision has been made to forego life-sustaining treatments. The third regards the evaluation of the decision and its implementation. The mission of pediatric intensive care has expanded to provide the best possible care to dying children and their families. Improving the quality of care received by dying children remains an ongoing challenge for every pediatric intensive care unit team member.

A "little bit illegal"? Withholding and withdrawing of mechanical ventilation in the eyes of German intensive care physicians

RESEARCH QUESTIONS AND BACKGROUND: This study explores a highly controversial issue of medical care in Germany: the decision to withhold or withdraw mechanical ventilation in critically ill patients. It analyzes difficulties in making these decisions and the physicians' uncertainty in understanding the German terminology of Sterbehilfe, which is used in the context of treatment limitation. Used in everyday language, the word Sterbehilfe carries connotations such as helping the patient in the dying process or helping the patient to enter the dying process. Yet, in the legal and ethical discourse Sterbehilfe indicates several concepts: (1) treatment limitation, i.e., withholding or withdrawing life-sustaining treatment (passive Sterbehilfe), (2) the use of medication for symptom control while taking into account the risk of hastening the patient's death (indirekte Sterbehilfe), and (3) measures to deliberately terminate the patient's life (aktive Sterbehilfe). The terminology of Sterbehilfe has been criticized for being too complex and misleading, particularly for practical purposes.

MATERIALS AND METHODS

An exploratory study based on qualitative interviews was conducted with 28 physicians from nine medical intensive care units in tertiary care hospitals in the German federal state of Baden-Wuerttemberg. The method of data collection was a problem-centered, semi-structured interview using two authentic clinical case examples. In order to shed light on the relation between the physicians' concepts and the ethical and legal frames of reference, we analyzed their way of using the terms passive and aktive Sterbehilfe.

RESULTS

Generally, the physicians were more hesitant in making decisions to withdraw rather than withhold mechanical ventilation. Almost half of them assumed a categorical prohibition to withdraw any mechanical ventilation and more than one third felt that treatment ought not to be withdrawn at all. Physicians showed specific uncertainty about classifying the withdrawal of mechanical ventilation as passive Sterbehilfe, and had difficulties understanding that terminating ventilation is not basically illegal, but the permissibility of withdrawal depends on the situation.

CONCLUSIONS

The physicians' knowledge and skills in interpreting clinical ethical dilemmas require specific improvement on the one hand; on the other hand, the terms passive and aktive Sterbehilfe are less clear than desirable and not as easy to use in clinical practice. Fear of making unjustified or illegal decisions may motivate physicians to continue (even futile) treatment. Physicians strongly opt for more open discussion about end-of-life care to allow for discontinuation of futile treatment and to reduce conflict.

Outcome of patients who have therapy withheld or withdrawn in ICU

Many deaths among patients treated in intensive care units (ICUs) occur following the withdrawal or withholding of life support. Following limitation of life support, most of these patients die in the ICU or ward after the decision to limit life support is made, although some may survive to hospital discharge. This study described the characteristics of patients who had life support limitations in ICU and their subsequent in-hospital and out-of-hospital survival using linked data from the state's death registry. Among 26,019 ICU admissions between 1987 and 2002 there were 396 patients (1.5%) who had life support limitations. The hospital mortality of the patients who had life support limitations was 97.7% and this accounted for 16.2% of the hospital mortality of all ICU admissions. Of the 396 patients who had life support limitations, 315 patients (79.5%) died in the ICU, 72 patients (18.2%) died in the wards and nine patients (2.3%) were discharged from hospital. Of these nine patients who survived to hospital discharge, four died within 10 days of hospital discharge and a further two died within six months. There were two patients, both with significant neurological disabilities at hospital discharge, who survived for longer than three years after hospital discharge. Long-term survival in critically ill patients who had life support limitations was very rare in this ICU.

Ethical considerations at the end of life in the intensive care unit

Intensive care units (ICUs) confront the healthcare system with end-of-life situations and ethical dilemmas surrounding death. It is necessary for all providers who treat dying patients to have a working knowledge of the philosophical principles that are fundamental to biomedical ethics. Those principles, however, are insufficient for compassionate care. To function well in the intensive care unit, one also must appreciate the behaviors that surround mortality. Human conduct is not predicated solely on rules; complex, unpredictable interactions are the norm. Palliative care, moving forward as a discipline, will become the perfect complement to intensive medical care, rather than being seen as an embodiment of its failures. We need to be as aggressive about respecting patient dignity as we are about using the technology that is central to health care. This article will outline end-of-life ethical principles, explore the sociology that influences human interactions in intensive care units, and show how palliative care should guide behaviors to improve how we deal with death.

Informed consent for therapy and research in continuous renal replacement therapy: an international survey

OBJECTIVE

To study the approach of health care workers (HCW) to informed consent for therapy and research in the field of continuous renal replacement therapy (CRRT).

DESIGN

Administration of questionnaire.

SETTING

Two International Courses on Critical Care Nephrology (CCN) held in Vicenza and Melbourne.

PARTICIPANTS

Eight hundred and twenty one course participants.

RESULTS

We obtained 349 analysable questionnaires (42.5% of participants). Only 22.5% of responders always obtain informed consent for CRRT; 70.3% just inform patients/relatives without seeking consent, 7.1% never obtain informed consent. In ICU patients, informed consent is considered 'good, correct and feasible' for therapy and for research by only 13% and 27% of responders, respectively. Consent for clinical research obtained from the next of kin or legal guardian is considered good, correct and feasible' by 56.3% of respondents, while 39.1% believe that next of kin or legal guardians can not really make informed decisions. Finally, nearly half of responders think that present rules hamper research in ICU. For many questions, significant variability of responses was found according to profession, specialty and origin of responders.

CONCLUSIONS

In the field of CRRT, stated practice, beliefs and currently accepted ethical standards vary greatly according to profession, specialty and origin. A significant disagreement between what is widely promoted to be the 'correct' approach and what is currently done is evident.

Attitudes of European physicians, nurses, patients, and families regarding end-of-life decisions: the ETHICATT study

OBJECTIVE

To evaluate attitudes of Europeans regarding end-of-life decisions.

DESIGN AND SETTING

Responses to a questionnaire by physicians and nurses working in ICUs, patients who survived ICU, and families of ICU patients in six European countries were compared for attitudes regarding quality and value of life, ICU treatments, active euthanasia, and place of treatment.

MEASUREMENTS AND RESULTS

Questionnaires were distributed to 4,389 individuals and completed by 1,899 (43%). Physicians (88%) and nurses (87%) found quality of life more important and value of life less important in their decisions for themselves than patients (51%) and families (63%). If diagnosed with a terminal illness, health professionals wanted fewer ICU admissions, uses of CPR, and ventilators (21%, 8%, 10%, respectively) than patients and families (58%, 49%, 44%, respectively). More physicians (79%) and nurses (61%) than patients (58%) and families (48%) preferred being home or in a hospice if they had a terminal illness with only a short time to live.

CONCLUSIONS

Quality of life was more important for physicians and nurses than patients and families. More medical professionals want fewer ICU treatments and prefer being home or in a hospice for a terminal illness than patients and families.

[Ethical attitudes in Spanish pediatric critical care units]

OBJECTIVES

To assess physicians' awareness and experience of ethical problems that arise when dealing with critically ill children in pediatric intensive care units (PICUs).

MATERIAL AND METHODS

Questionnaires containing 20 questions about ethical dilemmas and attitudes related to the care of children admitted to PICUs were mailed to 43 PICUs in Spain.

RESULTS

Ninety-five responses corresponding to 24 residents and 71 attending physicians were received from 21 PICUs. The occurrence of ethical dilemmas in the PICU was recognized by 96.8 % of the respondents. The most frequent method of solving these problems was through medical consensus (80 %), while family participation in the decision making process was highly variable. A total of 95.8 % of respondents stated that decisions to limit therapy were made in their PICU, although only one third of these decisions were written in the medical record. The most frequent form of therapeutic limitation was the do not resuscitate order. One third (32.6 %) of participants considered there were ethical differences between withdrawal and withholding of treatment. Attending physicians had greater experience of therapeutic limitation than did residents, but their opinions on the subject were similar.

CONCLUSIONS

Ethical dilemmas are common in the PICU. In this setting, decisions about limitation of therapy are frequent, although many physicians admit to not being clear on this issue or on other aspects of clinical ethics. Family members' participation in the decision making process is insufficient in Spanish PICUs.

Ethical, political, and social aspects of high-technology medicine: Eos and Care

OBJECTIVE

We discuss biosocial aspects of high-technology medicine (HTM) to provide a global view of the current model of medicine in the developed world and its consequences.

METHODS

We analyze changes in the concept of death and in the use and cost of HTM. The consequences of HTM on the delivery of basic medical care within and among countries are discussed. Concepts derived from Greek mythology are used to illustrate the problems associated with HTM.

RESULTS

HTM can be extremely effective in individual cases, but it poses important bioethical and biosocial problems. A major problem is related to the possibility of manipulating the process of dying and the consequent alteration in the social concept of death, which, if not carefully regulated, risks transforming medicine into an expensive way of pursuing pointless dreams of immortality (myth of Eos). Another problem is related to the extraordinary amount of resources necessary for HTM. This model of medicine (which is practiced daily) has limited sustainability, can work only in highly developed countries, may contribute to unequal access to health care, and has negligible positive impact on global health and survival.

CONCLUSIONS

HTM poses very important biosocial questions that need to be addressed in a wider and transparent debate, in the best interest of society and HTM as well.

Evaluation of Changes in Forgoing Life-Sustaining Treatment in Israeli ICU Patients

INTRODUCTION

Over the last several years, there have been legal decisions and changes in medical directives concerning end-of-life decisions in Israel.

METHODS

The data were compared to evaluate the changes in the frequency and types of forgoing of life-sustaining treatment (FLST) in patients who were admitted to the ICU during period I (November 1994 to July 1995) and period II (January 1998 to January 1999).

RESULTS

During period I, there were 385 ICU admissions, and during period II there were 627 ICU admissions. In period I, FLST or death occurred in 13.5% of patients, and in 12% in period II. There was no significant difference in cardiopulmonary resuscitation (9% vs 13%, respectively), withholding therapy (90% vs 91%, respectively), or withdrawing therapy (0% vs 0%, respectively) between the two study periods.

CONCLUSIONS

There was no significant change in the frequency or types of FLST in an Israeli ICU between 1994 and 1998, despite passage of a new Patients' Rights Law and the issuing of a Ministry of Health directive on the treatment of the terminally ill, both of which occurred in 1996, and recent district court decisions favoring the termination of life-sustaining therapies.

Ethical and Practical Principles Underlying the End of Life Decisions

"I will not relinquish old age, if it leaves my better part intact. But, if it begins to shake my mind, if it destroys its faculties one by one, if it leaves me not life but breath, I will depart from the putrid or tottering edifice. If I must suffer without hope or relief, I will depart, not through fear of the pain itself, but because it prevents all for which I would live." Seneca, the great Roman statesman of 1st century AD, spoke these words 2 millennia before the Netherlands became, on November 28, 2000, the first country in the world to legalize euthanasia. The decisions pertaining to end of life, whether legalized or otherwise, are practiced in many parts of the world but not reported on account of legal implications. Lack of awareness regarding the distinction between different procedures on account of legal status granted to them in some countries is the other area of concern. Debate among the medical practitioners, lawmakers, and the public taking into consideration the cultural, social, and religious ethos will lead to increased awareness, more safeguards, and improvement of medical decisions concerning the end of life.

Parental role in medical decision-making: fact or fiction? A comparative study of ethical dilemmas in French and American neonatal intensive care units

Neonatal intensive care has been studied from an epidemiological, ethical, medical and even sociological perspective, but little is known about the impact of parental involvement in decision-making, especially in critical cases. We rely here on a comparative, case-based approach to study the parental role in decision-making within two technologically identical but culturally and institutionally different contexts: France and the United States. These contexts rely on two opposed models of decision-making: parental autonomy in the United States and medical paternalism in France. This paternalism model excludes parents from the decision-making process. We investigate whether parental involvement leads to different outcomes from exclusively medically determined decisions or whether "technological imperatives" outplay all other factors to shape a unique, 'medically optimal' outcome. Using empirical data generated from extensive ethnographic fieldwork, in-depth interviews with 60 clinicians and 71 parents and chart review over a year in two neonatal intensive care units (one in France and one in the US), we analyze the factors that can explain the observed differences in decision-making in medically identical cases. Parental involvement and the legal context play a less role than physicians' differential use of certainty versus uncertainty in prognosis, a conclusion that corroborates the fact that medical control over ethical dilemmas remains even in the context of autonomy. French physicians do not ask parents permission to withdraw care (as expected in a paternalistic context); but symmetrically, American neonatologists (despite the prevailing autonomy model) tend not to ask permission to continue. The study provides an analysis of the making of "ethics", with an emphasis on how decisions are conceptualized as ethical dilemmas. The final conclusion is that the ongoing medical authority on ethics remains the key issue.

Forgoing life-sustaining treatments in children: a comparison between Northern and Southern European pediatric intensive care units

OBJECTIVES

This study was conducted to determine how the decision-making process to forgo life support differs between southern and northern European pediatric intensive care units.

DESIGN

Multiple-center, prospective study.

SETTING

Thirty-nine pediatric intensive care units: 12 from northern Europe and 27 from southern Europe.

PATIENTS

All consecutive deaths were recorded over a 4-month period. Group 1 and group 2 included patients who died in northern and southern pediatric intensive care units, respectively.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Three hundred fifty children were enrolled, 68 in group 1 and 282 in group 2. The decision to forgo life-sustaining treatment was made in 116 children (group 1, n = 32; group 2, n = 84). In both groups, the decision was discussed by caregivers during a formal meeting. The decision to forgo life-sustaining treatment was more often made in northern countries than in southern ones (47% vs. 30%, p =.02). Parents were informed of this decision in 95% of cases in group 1 vs. 68% in group 2 (p =.01). In both groups, the final decision was made by the medical staff. Parents' contributions to the decision-making process did not differ between the two groups according to the practitioners' opinion. The decision was documented in the medical charts in 100% of the cases in group 1 and in 51% of the cases in group 2 (p =.0001).

CONCLUSIONS

The decision-making process appears to be similar between northern and southern European countries. The respective contributions of the parents and the medical staff in the final decision itself seem to be identical between northern and southern countries. However, in northern European countries, the level of parents' information about the decision-making process appears higher and the decision is more often documented in the medical chart.

Autonomy gone awry: a cross-cultural study of parents' experiences in neonatal intensive care units

This paper examines parents' experiences of medical decision-making and coping with having a critically ill baby in the Neonatal Intensive Care Unit (NICU) from a cross-cultural perspective (France vs. U.S.A.). Though parents' experiences in the NICU were very similar despite cultural and institutional differences, each system addresses their needs in a different way. Interviews with parents show that French parents expressed overall higher satisfaction with the care of their babies and were better able to cope with the loss of their child than American parents. Central to the French parents' perception of autonomy and their sense of satisfaction were the strong doctor-patient relationship, the emphasis on medical certainty in prognosis versus uncertainty in the American context, and the "sentimental work" provided by the team. The American setting, characterized by respect for parental autonomy, did not necessarily translate into full parental involvement in decision-making, and it limited the rapport between doctors and parents to the extent of parental isolation. This empirical comparative approach fosters a much-needed critique of philosophical principles by underscoring, from the parents' perspective, the lack of "emotional work" involved in the practice of autonomy in the American unit compared to the paternalistic European context. Beyond theoretical and ethical arguments, we must reconsider the practice of autonomy in particularly stressful situations by providing more specific means to cope, translating the impersonal language of "rights" and decision-making into trusting, caring relationships, and sharing the responsibility for making tragic choices.

Circumstances surrounding end of life in a pediatric intensive care unit

OBJECTIVE

Approximately 60% of deaths in pediatric intensive care units follow limitation or withdrawal of life-sustaining treatment (LST). We aimed to describe the circumstances surrounding decision making and end-of-life care in this setting.

METHODS

We conducted a prospective, descriptive study based on a survey with the intensivist after every consecutive death during an 8-month period in a single multidisciplinary pediatric intensive care unit. Summary statistics are presented as percentage, mean +/- standard deviation, or median and range; data are compared using the Mantel-Haenszel test and shown as survival curves.

RESULTS

Of the 99 observed deaths, 27 involved failed cardiopulmonary resuscitation; of the remaining 72, 39 followed withdrawal/limitation (W/LT) of LST, 20 were do not resuscitate (DNR), and 13 were brain deaths (BDs). Families initiated discussions about forgoing LST in 24% (17 of 72) of cases. Consensus between caregivers and staff about forgoing LST as the best approach was reached after the first meeting with 51% (35 of 68) of families; 46% (31 of 68) required >or=2 meetings (4 not reported). In the DNR group, the median time to death after consensus was 24 hours and for W/LT was 3 hours. LST was later withdrawn in 11 of 20 DNR cases. The family was present in 76% (45 of 59) of cases when LST was forgone. The dying patient was held by the family in 78% (35 of 45) of these occasions.

CONCLUSIONS

More than 1 formal meeting was required to reach consensus with families about forgoing LST in almost half of the patients. Families often held their child at the time of death. The majority of children died quickly after the end-of-life decision was made.

End-of-life decisions in Swedish ICUs. How do physicians from the admitting department reason?

OBJECTIVE

To study how physicians from the admitting department reason during the decision-making process to forego life-sustaining treatment of patients in intensive care units (ICUs).

DESIGN

Qualitative interview that applies a phenomenological approach.

SETTING

Two ICUs at one secondary and one tertiary referral hospital in Sweden.

PARTICIPANTS

Seventeen admitting-department physicians who have participated in decisions to forego life-sustaining treatment.

RESULTS

The decision-making process as it appeared from the physicians' experiences was complex, and different approaches to the process were observed. A pattern of five phases in the process emerged in the interviews. The physicians described the process principally as a medical one, with few ethical reflections. Decision-making was mostly done in collaboration with other physicians. Patients, family and nurses did not seem to play a significant role in the process.

CONCLUSION

This study describes how physicians reasoned when confronted with real patient situations in which decisions to forego life-sustaining treatment were mainly based on medical--not ethical--considerations.

Discrepancies between perceptions by physicians and nursing staff of intensive care unit end-of-life decisions

Several studies have pointed out ethical shortcomings in the decision-making process for withholding or withdrawing life-supporting treatments. We conducted a study to evaluate the perceptions of all caregivers involved in this process in the intensive care unit. A closed-ended questionnaire was completed by 3,156 nursing staff members and 521 physicians from 133 French intensive care units (participation rate, 42%). Decision-making processes were perceived as satisfactory by 73% of physicians and by only 33% of the nursing staff. More than 90% of caregivers believed that decision-making should be collaborative, but 50% of physicians and only 27% of nursing staff members believed that the nursing staff was actually involved (p < 0.001). Fear of litigation was a reason given by physicians for modifying information given to competent patients, families, and nursing staff. Perceptions by nursing staff may be a reliable indicator of the quality of medical decision-making processes and may serve as a simple and effective tool for evaluating everyday practice. Recommendations and legislation may help to build consensus and avoid conflicts among caregivers at each step of the decision-making process.

Withdrawal of medical treatment in the ICU. A cohort study of 318 cases during 1994-2000

BACKGROUND

Many deaths in intensive care occur after life support has been withdrawn or withheld. In Sweden there are no guidelines for the withholding or withdrawal of life-sustaining treatments, and information on the frequency of such decisions is scarce. Open and conscious accounts of crucial standpoints in theses decisions are important. The aim of this study was to determine the incidence of decisions to withdraw medical therapy in a Swedish, general intensive care unit (ICU), the underlying reasons and outcomes.

METHODS

In this historical cohort study in a 10 bed ICU, we studied the records of the 3904 patients admitted during the period 1994-2000.

RESULTS

Medical therapy was withdrawn in 318 (8.1%) patients. During the study period, 466 patients died in the ICU, of which 191 (41.0%) had had a withdrawal decision. Of the 318 patients with a withdrawal decision followed up, 191 (60.1%) died in the ICU, 104 (32.7%) later on a general ward, and 23 (7.2%) were discharged alive from the hospital. The main reasons for withdrawing therapy were failure to respond to treatment in 119 (37%), poor prognosis of the acute disease in 119 (37%), poor prognosis of coexisting chronic disease in 62 (20%) and the patient's own request in 18 (6%) of the cases. The median time from ICU-admission to a withdrawal decision was 2.8 days. The median time from a withdrawal decision to death was 0.6 days (191 patients) in the ICU, 2.4 days (104 patients) in the general ward and 1.4 months (19 patients) for those dying after hospital discharge. In five cases a renewed evaluation was performed.

CONCLUSION

Medical therapy was withdrawn in the ICU in 8.1% of patients and the chief reasons were failure to respond to therapy or poor prognosis of the acute disease. Four patients were still alive five years later. The time interval from admission to a withdrawal decision was short.

End-of-life intensive care unit decisions, communication, and documentation: an evaluation of physician training

PURPOSE

The majority of patients dying in intensive care units (ICUs) do so after the forgoing of life-sustaining therapies (FLST). Communication between physicians, patients, and their families regarding the decision to FLST has not been evaluated in Israel.

MATERIALS AND METHODS

All patients who had FLST in a general ICU were enrolled in the study. We evaluated whether physicians communicated and documented the FLST decisions with patients or the patients' families. We also assessed the effect of the physician's geographic place of training on communication behavior.

RESULTS

Over a period of 8.5 months, 385 patients were admitted to a general ICU in Israel. Fifty-seven patients died or had FLST. Twelve of these 57 were excluded from the study. Thus, 45 (79%) patients had FLST and were enrolled in the study. All patients were deemed medically incompetent to make FLST decisions. In 24 (53%) patients, FLST was discussed with the family before the decision to forgo therapy. Discussion occurred later with 6 other families, who were unavailable at the time the FLST decision was made. In 15 patients, there were no discussions with families. American-trained physicians discussed FLST with 22 of 29 families initially and 5 other families later (93%), whereas the Eastern European-trained physicians discussed FLST with only 3 of 16 (19%) families (P <.001). Documentation of FLST was present in 26 (90%) patients of American-trained physicians and 8 (50%) patients of Eastern European-trained physicians (P <.001).

CONCLUSIONS

FLST is common in an Israeli ICU. Patients are not medically competent to make FLST decisions. American-trained physicians discuss and document FLST more often than Eastern European-trained physicians.

Acculturation of attitudes toward end-of-life care: a cross-cultural survey of Japanese Americans and Japanese

OBJECTIVE

Cross-cultural ethical conflicts are common. However, little is known about how and to what extent acculturation changes attitudes toward end-of-life care and advance care planning. We compared attitudes toward end-of-life care among Japanese Americans and Japanese in Japan.

DESIGN

Self-administered questionnaire in English and Japanese.

SETTING AND PARTICIPANTS

Community-based samples of Japanese Americans in Los Angeles and Japanese in Nagoya, Japan: 539 English-speaking Japanese Americans (EJA), 340 Japanese-speaking Japanese Americans (JJA), and 304 Japanese living in Japan (JJ).

MEASUREMENTS AND MAIN RESULTS

Few subjects (6% to 11%) had discussed end-of-life issues with physicians, while many (EJA, 40%; JJA, 55%; JJ, 54%) desired to do so. Most preferred group surrogate decision making (EJA, 75%; JJA, 57%; JJ, 69%). After adjustment for demographics and health status, desire for informing the patient of a terminal prognosis using words increased significantly with acculturation (EJA, odds ratio [OR] 8.85; 95% confidence interval, [95% CI] 5.4 to 14.3; JJA, OR 2.8; 95% CI 1.8 to 4.4; JJ, OR 1.0). EJA had more-positive attitudes toward forgoing care, advance care planning, and autonomous decision making.

CONCLUSION

Preference for disclosure, willingness to forgo care, and views of advance care planning shift toward western values as Japanese Americans acculturate. However, the desire for group decision making is preserved. Recognition of the variability and acculturation gradient of end-of-life attitudes among Japanese Americans may facilitate decision making and minimize conflicts. Group decision making should be an option for Japanese Americans.

French intensivists do not apply American recommendations regarding decisions to forgo life-sustaining therapy

OBJECTIVE

Recommendations for making and implementing decisions to forgo life-sustaining therapy in intensive care units have been developed in the United States, but the extent that they are realized in practice has yet to be measured.

DESIGN

Prospective, multicenter, 4-wk study. For each patient with an implemented decision to forgo life-sustaining therapy, the deliberation and decision implementation procedures were recorded.

SETTING

French intensive care units.

PATIENTS

All consecutive patients admitted to 26 French intensive care units.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Of 1,009 patients admitted, 208 died in the intensive care unit. A decision to forgo life-sustaining therapy was implemented in 105 patients. The number of supportive treatments forgone was 2.3 +/- 1.7 per patient. Decisions to forgo sustaining therapy were preceded by 3.5 +/- 2.5 deliberation sessions. Proxies were informed of the deliberations in 62 (59.1%) cases but participated in only 18 (17.1%) decisions. The patient's perception of his or her quality of life was rarely evaluated (11.5%), and only rarely did the decision involve evaluating the patient's wishes (7.6%), the patient's religious values (7.6%), or the cost of treatment (7.6%). Factors most frequently evaluated were medical team advice (95.3%), predicted reversibility of acute disease (90.5%), underlying disease severity (83.9%), and the patient's quality of life as evaluated by caregivers (80.1%).

CONCLUSIONS

A decision to withhold or withdraw life-sustaining therapy was implemented for half the patients who died in the French intensive care units studied. In many cases, the decision was taken without regard for one or more factors identified as relevant in U.S. guidelines.

[Ethics conflicts in the application of mechanical ventilation: analysis of the attitude of critical care and emergency professionals and students]

OBJECTIVE

To analyze the influence of prognosis, life quality or previous instructions in the decision making of applying an invasive (intubation/mechanical ventilation), conservative or palliative procedure.

MATERIAL AND METHODS

"Casuistry" methodology: opinion on the appropriate decision regarding five clinical histories representative of ethic conflicts with 542 health professionals (220 intensive care specialist, 150 emergency department professionals, 76 nurses, and 96 students). As control group, 26 students enrolled in a International Master on Bioethics.

RESULTS

A great inter-group variability was observed (p = 0.005) with a higher agreement with control group between students and lower with intensivists. The agreement observed was highest in cases with "total support" as the appropriate option (kappa 0.85, 0.69, and 0.66) than in cases with "palliative measures" as appropriate option (kappa 0.22 and 0.46).

CONCLUSIONS

1) A high variability was observed regarding decisions on instituting respiratory support. 2) Decisions regarding the restriction of therapeutic efforts are not accepted in the main, even in scenarios merging into futility, as permanent vegetative status. 3) Among severely deteriorated and handicapped patients, perceived life quality is more appreciated by the patient than that estimated objectively. 4) There is no a consensus opinion for the respect of previous guidelines of vital support refusal. 5) Age and deep psychic deficiency are not considered as cause of discrimination. These features may be considered typical of the mediterranean ethics, in which paternalism and charity are more appreciated values than autonomy.

Forgoing life-sustaining treatments: how the decision is made in French pediatric intensive care units

OBJECTIVES

The decision to forgo life support is frequently made in pediatric intensive care units (PICUs). A group of experts is currently preparing recommendations for guidelines concerning this decision-making process in France. We have performed a prospective study to help the experts. This study documents how children die in French PICUs and how the decision to limit life support is made.

DESIGN

A multicenter, prospective, cross-sectional study.

SETTING

Thirty-three multidisciplinary PICUs in university hospitals.

PATIENTS

All consecutive deaths were recorded over a 4-month period. Children who died after a medical decision to forgo life-sustaining treatment were included in group 1 and children who died from other causes were included in group 1.

MAIN RESULTS

A total of 264 consecutive children died, 40.1% from group 1 and 59.8% from group 2. Patients of both groups were primarily admitted for acute respiratory failure (group 1, 50.8%; group 2, 52.6%). Neurologic emergencies were more frequent in patients in group 1, whereas patients with cardiovascular failures were more frequent in group 2. When there was a question of whether to pursue life-sustaining treatment, the parents' opinions were recorded in 72.1% of cases. A specific meeting was called to make this decision in 80.1% of cases. This meeting involved the medical staff in all cases. Parents were aware of the meeting in 10.7% of cases. The conclusion of the meeting was reported to the parents in 18.7% of cases and documented in the patient's medical record in 16% of cases. Experts who were not members of the PICU staff were invited to give their opinion in 62.2% of cases.

CONCLUSIONS

The decision to forgo life-sustaining treatment is frequently made for children dying in French PICUs. Guidelines must be available to help the medical staff reach this decision. Knowledge of the decision-making process in French PICUs provides the experts with information needed to elaborate such recommendations.

Forgoing life support in western European intensive care units: the results of an ethical questionnaire

OBJECTIVE

To determine current views of European intensive care physicians regarding end-of-life decisions.

DESIGN

A questionnaire was sent to all physician members of the European Society of Intensive Care Medicine. All questionnaires were anonymous.

RESULTS

A total of 504 completed questionnaires from 16 western European countries were analyzed. Eighty-seven percent of the respondents were male. Forty-six percent of respondents said that intensive care unit admissions were generally or commonly affected by bed shortages, particularly in the south. Nevertheless, 73% of units frequently admit patients with no hope of survival, although only 33% of respondents felt that such patients should be admitted. Eighty percent of respondents felt that written do-not-resuscitate orders should be applied, but only 58% did so, with a wide variation according to country (from 8% in Italy to 91% in The Netherlands). Ninety-three percent of physicians sometimes withhold treatment from patients with no hope of a meaningful life, but withdrawal of treatment is less common. Forty percent of respondents said that they would deliberately administer large doses of drugs to such patients until death ensued. Forty-nine percent of respondents involved staff, patients, and family in end-of-life decisions. Forty-five percent of respondents felt that an ethics consultation was useful in such situations. Physicians in the countries of southern Europe were less likely than those in the north to apply do-not-resuscitate orders, withhold treatment, and discuss such issues with the patients. However, they were more likely to value the opinion of an ethics consultant.

CONCLUSIONS

Intensive care unit admissions are frequently limited by the availability of beds across Europe, particularly in the south and in the United Kingdom, yet 73% of intensivists still admit patients with no hope of survival. When treating patients with no hope of survival, 40% of intensivists will deliberately administer large doses of drugs until death ensues. There are interesting differences between what a physician actually does and what he or she believes should be done with regard to various ethical questions. Important differences in attitudes also exist between European countries.
