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

Relieving suffering or intentionally hastening death: where do you draw the line?

OBJECTIVE

End-of-life practices vary worldwide. The objective was to demonstrate that there is no clear-cut distinction between treatments administered to relieve pain and suffering and those intended to shorten the dying process.

DESIGN

Secondary analysis of a prospective, observational study.

SETTING

Thirty-seven intensive care units in 17 European countries.

PATIENTS

Consecutive patients dying or with any limitation of therapy.

INTERVENTIONS

Evaluation of the type of end-of-life category; dates and times of intensive care unit admission, death, or discharge; and decisions to limit therapy, medication, and doses used for active shortening of the dying process and the intent of the doctors prescribing the medication.

MEASUREMENTS AND MAIN RESULTS

Limitation of life-sustaining therapy occurred in 3,086 (72.6%) of 4,248 patients, and 94 (2.2%) underwent active shortening of the dying process. Medication for active shortening of the dying process included administration of opiates (morphine to 71 patients) or benzodiazepines (diazepam to 54 patients) alone or in combination. The median dosage for morphine was 25.0 mg/hr and for diazepam 20.8 mg/hr. Doses of opiates and benzodiazepines were no higher than mean doses used with withdrawal in previous studies in 20 of 66 patients and were within the ranges of doses used in all but one patient. Doctors considered that medications for active shortening of the dying process definitely led to the patient's death in 72 patients (77%), probably led to the patient's death in 11 (12%), and were unlikely to have led to death in 11 (12%) patients.

CONCLUSIONS

There is a gray area in end-of-life care between treatments administered to relieve pain and suffering and those intended to shorten the dying process.

To die, to sleep: US physicians' religious and other objections to physician-assisted suicide, terminal sedation, and withdrawal of life support

This study analyzes data from a national survey to estimate the proportion of physicians who currently object to physician-assisted suicide (PAS), terminal sedation (TS), and withdrawal of artificial life support (WLS), and to examine associations between such objections and physician ethnicity, religious characteristics, and experience caring for dying patients. Overall, 69% of the US physicians object to PAS, 18% to TS, and 5% to WLS. Highly religious physicians are more likely than those with low religiosity to object to both PAS (84% vs 55%, P < .001) and TS (25% vs 12%, P < .001). Objection to PAS or TS is also associated with being of Asian ethnicity, of Hindu religious affiliation, and having more experience caring for dying patients. These findings suggest that, with respect to morally contested interventions at the end of life, the medical care patients receive will vary based on their physicians' religious characteristics, ethnicity, and experience caring for dying patients.

Deciding who to admit to a critical care unit

Scarce resources may cause doctors to be pessimistic about prognosis and refuse critical care admissions

Perceptions of "futile care" among caregivers in intensive care units

BACKGROUND

Many caregivers in intensive care units (ICUs) feel that they sometimes provide inappropriate or excessive care, but little is known about their definition of "futile care" or how they attempt to limit its impact. We sought to explore how ICU staff define medically futile care, why they provide it and what strategies might promote a more effective use of ICU resources.

METHODS

Using semi-structured interviews, we surveyed 14 physician directors, 16 nurse managers and 14 respiratory therapists from 16 ICUs across Ontario. We analyzed the transcripts using a modified grounded-theory approach.

RESULTS

From the interviews, we generated a working definition of medically futile care to mean the use of considerable resources without a reasonable hope that the patient would recover to a state of relative independence or be interactive with his or her environment. Respondents felt that futile care was provided because of family demands, a lack of timely or skilled communication, or a lack of consensus among the treating team. Respondents said they were able to resolve cases of futile care most effectively by improving communication and by allowing time for families to accept the reality of the situation. Respondents felt that further efforts to limit futile care should focus on educating the public and health care professionals about the role of the ICU and about alternatives such as palliative care; mandating early and skilled discussion of resuscitation status; establishing guidelines for admission to the ICU; and providing legal and ethical support for physicians who encounter difficulties. There was a broad consistency in responses among all disciplines.

INTERPRETATION

ICU physicians, nurses and respiratory therapists have similar and well-formed opinions about how to define and resolve medically futile care and where to focus future efforts to limit the impact of futile care in the ICU.

Withdrawing Life-Sustaining Treatment: Ethical Considerations

Withdrawing life-supporting technology from patients who are irremediably ill is morally troubling for caregivers, patients, and families. Interventions that enable clinicians to delay death create situations in which the dignity and comfort of dying patients may be sacrificed to spare professionals and families from their elemental fear of death. Understanding of the limits of treatment, expertise in palliation of symptoms, skillful communication, and careful orchestration of controllable events can help to manage the withdrawal of life support appropriately.

End-of-life decision making in neonates and infants: comparison of The Netherlands and Belgium (Flanders)

AIM

We compared the results of two recent studies on end-of-life decisions (ELDs) for neonates and infants in Belgium (Flanders) and The Netherlands.

METHODS

Questionnaires were sent to physicians who reported the death of a child under the age of 1 (Belgium: n = 292, response 87%; Netherlands: n = 249, response 84%). The questionnaires included structured questions about whether death had been preceded by ELDs, and about the decision-making process.

RESULTS

In both countries, in about 25% of all deaths a life-sustaining treatment was withheld, and in about 40% pain or other symptoms were alleviated taking into account that death might be hastened. In Belgium, a life-sustaining treatment was less often withdrawn than in The Netherlands (32% vs. 50%, respectively). Drugs were administered with the explicit intention of hastening death in similar percentages of all deaths (Belgium: 7%; Netherlands: 9%). Dutch physicians more often than Belgian physicians discussed ELDs with parents (96% vs. 81%, respectively), and with colleague physicians (94% vs. 80%, respectively).

CONCLUSIONS

End-of-life decision making in severely ill neonates seems to be rather similar in Belgium and The Netherlands. Differences are that Dutch physicians more often withdraw life-sustaining treatment. Furthermore, parents and colleague physicians are more often involved in the decision making in The Netherlands.

Physician discussions with terminally ill patients: a cross-national comparison

A major issue in the care of terminally ill patients is communication and information provision. This paper reports the extent to which physicians in Australia, Belgium, Denmark, Italy, the Netherlands, Sweden and Switzerland discuss topics relevant to end of life care with terminally ill patients and their relatives (without first informing the patient), and possible associations between physician-specific characteristics and such discussions. Response rates to the postal survey ranged from 39% to 68% (n =10139). Physicians in most of the countries except Italy ;in principle, always' discuss issues related to terminal illness with their patients but not with patients' relatives without first informing the patient, unless the relatives ask. Cross-national differences remained strong after controlling for physician characteristics. The majority of physicians appeared to support the principle of patient-centred care to terminally ill patients, consistent with palliative care philosophy and with the law and/or professional guidelines in most of the countries studied.

The importance of religious affiliation and culture on end-of-life decisions in European intensive care units

OBJECTIVE

To determine the influence of religious affiliation and culture on end-of-life decisions in European intensive care units (ICUs).

DESIGN AND SETTING

A prospective, observational study of European ICUs was performed on consecutive patients with any limitation of therapy. Prospectively defined end-of-life practices in 37 ICUs in 17 European countries studied from 1 January 1999 to 30 June 2000 were compared for frequencies, patterns, timing, and communication by religious affiliation of physicians and patients and regions.

RESULTS

Of the 31,417 patients 3,086 had limitations. Withholding occurred more often than withdrawing if the physician was Jewish (81%), Greek Orthodox (78%), or Moslem (63%). Withdrawing occurred more often for physicians who were Catholic (53%), Protestant (49%), or had no religious affiliation (47%). End-of-life decisions differed for physicians between regions and who had any religious affiliation vs. no religious affiliation in all three geographical regions. Median time from ICU admission to first limitation of therapy was 3.2 days but varied by religious affiliation; from 1.6 days for Protestant to 7.6 days for Greek Orthodox physicians. Median times from limitations to death also varied by physician's religious affiliation. Decisions were discussed with the families more often if the physician was Protestant (80%), Catholic (70%), had no religious affiliation (66%) or was Jewish (63%).

CONCLUSIONS

Significant differences associated with religious affiliation and culture were observed for the type of end of life decision, the times to therapy limitation and death, and discussion of decisions with patient families.

End-of-life patients, intensive care and consent: difficulties facing French intensivists

BACKGROUND

The French legislature passed a law in 2005 that assigns a new role to the physician and redefines his liability in end-of-life decisions.

METHOD

This law is presented and discussed in context with current French legal practice.

RESULTS

This law emphasizes patient autonomy, advocating that the patient be fully informed before treatment, and creates specific procedures to be followed according to whether the patient is conscious or unconscious. In the latter situation, the law reinforces the role of both the patient's surrogate and the patient's advance directives in establishing consent. In these extreme situations, doctors have the option to request a second medical opinion. This joint decision-making procedure is laid down by law and becomes obligatory in the interests of transparency.

CONCLUSION

Respect for patients' consent implies the possibility that they may refuse medical care, creating an ethical and legal dilemma of providing medical care or respecting the patients' wishes. The key issue concerning end-of-life patients rests in the decisions taken concerning the continuation or withdrawal of life support and the administration of palliative care.

Family presence and environmental factors at the time of a patient's death in an ICU

BACKGROUND

In an intensive care unit (ICU), privacy and proximity are reported to be important needs of dying patients and their family members. It is assumed that good communication between the ICU team and families about end-of-life decisions improves the possibilities of meeting families' needs, thus guaranteeing a dignified and peaceful death in accordance with end-of-life care guidelines. The aim of this study was to explore the circumstances under which patients die in Swedish ICUs by reporting on the presence of family and whether patients die in private or shared rooms. An additional aim was to investigate the frequency of end-of-life decisions and whether nurses and family members were informed about such decisions.

METHODS

A questionnaire based on the research questions was completed when a patient died in the 10 ICUs included in the study. Data were collected on 192 deaths.

RESULTS

Forty per cent of the patients died without a next of kin at the bedside and 46% of deaths occurred in a shared room. This number decreased to 37% if a family member was present. Patients without a family member at their bedside received less analgesics and sedatives. There was a significant relationship between family presence, expected death and end-of-life decisions.

CONCLUSIONS

The results indicate the necessity of improving the ICU environment to promote the need for proximity and privacy for dying patients and their families. The study also highlights the risk of underestimating the needs of patients without a next of kin at their bedside at the time of death.

Being an intensive care nurse related to questions of withholding or withdrawing curative treatment

AIMS AND OBJECTIVES

The aim of the study was to acquire a deeper understanding of what it is to be an intensive care nurse in situations related to questions of withholding or withdrawing curative treatment.

BACKGROUND

Nurses in intensive care units regularly face critically ill patients. Some patients do not benefit from the treatment and die after days or months of apparent pain and suffering. A general trend is that withdrawal of treatment in intensive care units is increasing. Physicians are responsible for decisions concerning medical treatment, but as nurses must carry out physicians' decisions, they are involved in the consequences.

DESIGN AND METHODS

The research design was qualitative, based on interpretative phenomenology. The study was carried out at an adult intensive care unit in Norway. Data were collected by group interviews inspired by focus group methodology. Fourteen female intensive care nurses participated, divided into two groups. Colaizzi's model was used in the process of analysis.

RESULTS

The analysis revealed four main themes which captured the nurses' experiences: loneliness in responsibility, alternation between optimism and pessimism, uncertainty--a constant shadow and professional pride despite little formal influence. The essence of being an intensive care nurse in the care of patients when questions were raised concerning curative treatment or not, was understood as 'being a critical interpreter and a dedicated helper.'

CONCLUSIONS

The findings underpin the important role of intensive care nurses in providing care and treatment to patients related to questions of withholding or withdrawing curative treatment.

RELEVANCE TO CLINICAL PRACTICE

The findings also show the need for physicians, managers and intensive care nurses themselves to recognize the burdens intensive care nurses carry and to appreciate their knowledge as an important contribution in decision making.

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.

[Mechanical ventilation and medical futility or dysthanasia, the dialectic of high technology in intensive medicine]

Dysthanasia or any of its synonyms is a consequence of excessive technical science, without any reasonable chance of achieving a therapeutic benefit for the patient. Medical futility is a distressing ethical dilemma of intensive care medicine. Its recognition has led to a precept support in various institutions and organizations. Not withdrawing or withholding mechanical ventilation in certain circumstances can be considered as a paradigmatic model of medical futility. The understanding of this posture implies a philosophical approach and reflexion of medical practice.

End-of-life practices at a Lebanese hospital: courage or knowledge?

End-of-life care requires knowledgeable and culturally sensitive clinicians to assist patients and families dealing with the difficult journey of death. The authors present important end-of-life considerations for health care providers dealing with culturally diversified patients. A case study approach is used illustrating two case vignettes derived from the practice of an intensive care setting of a tertiary teaching facility in a large urban area in Lebanon. In a multidisciplinary fashion, practices of end of life were explored and a protocol developed to guide health care providers. Special cultural values were identified such as importance of family involvement and religious beliefs. Implications for practice are described.

Forgoing life sustaining treatments: differences and similarities between North America and Europe

BACKGROUND

As evidence exist that severe neurological damage or prolonged death after inappropriate CPR could occur, restraints and indications for CPR were perceived as necessary. The objective of this review is to examine policies and attitudes towards end-of-life decisions in Europe and North America and to outline differences and similarities.

METHODS

A bibliographic database search from 1990 to 2006 was performed using the following terms: do-not-resuscitate orders, end-of-life decisions, withholding/withdrawal of life-sustaining treatments, medical futility and advanced directives. Eighty-eight articles, out of 305 examined, were analyzed and their data systematically reported and compared where possible. They consisted of studies, questionnaires and surveys answering the following questions: percentage of deaths of critical patients preceded by do-not-resuscitate orders, factors affecting the decision for do-not-resuscitate orders, people involved in this decision (patient, surrogates and medical staff) and how it was performed.

RESULTS

There is an evident gap between the North American use of standard and formal procedures compared with Europe. Second, they diverge in the role acknowledged to surrogates in the decisional process, as in Europe, restraints and reserves to accept surrogates as decision makers seem still strong and a paternalistic approach at the end-of-life is still present.

CONCLUSION

Incidentally, despite the predictable differences between Europe and North America, concerns do exist about the actual extent of autonomy wished by patients and surrogates. It is important to highlight these findings, as the paternalistic attitude, too often negatively depicted, could be, according to the best medical practice, justified and more welcomed in some instances.

Patient Refusal of Emergency Cesarean Delivery

OBJECTIVE

To compare the attitudes of a large sample of obstetricians from eight European countries toward a competent woman's refusal to consent to an emergency cesarean delivery for acute fetal distress.

METHODS

Obstetricians' attitudes in response to a hypothetical clinical case were surveyed through an anonymous, self-administered questionnaire. The sample included 1,530 obstetricians (response rate 77%) from 105 maternity units (response rate 70%) in eight countries: France, Germany, Italy, Luxembourg, Netherlands, Spain, Sweden and the United Kingdom.

RESULTS

In every country, the majority of obstetricians would keep trying to persuade the woman, telling her that failure to perform cesarean delivery might result in the fetus surviving with disability, or even that her own life might be endangered. In Spain, France, Italy, and, to a lesser extent, Germany and Luxembourg, a consistent proportion of physicians would seek a court order to protect fetal welfare or avoid possible legal liability or both. In the United Kingdom, Sweden, and Netherlands, several respondents (59%, 41%, and 37%, respectively) would accept the woman's decision and assist vaginal delivery. Only a small minority (from 0 in the United Kingdom to 10% in France) would proceed with cesarean delivery without a court order.

CONCLUSION

Case law arising from a few countries (United States, Canada, and the United Kingdom) and professional guidelines favoring women's autonomy have not solved the underlying ethical conflict, and in Europe acceptance of a woman's right to refuse cesarean delivery, at least in emergency situations, is not uniform. Differing attitudes between obstetricians from the eight countries may reflect diverse legal and ethical environments.

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.

Do-not-resuscitate decisions in six European countries*

OBJECTIVE

To study and compare the incidence and main background characteristics of do-not-resuscitate (DNR) decision making in six European countries.

DESIGN

Retrospective.

SETTING

We studied DNR decisions simultaneously in Belgium (Flanders), Denmark, Italy (four regions), the Netherlands, Sweden, and Switzerland (German-speaking part). In each country, random samples of death certificates were drawn from death registries to which all deaths are reported. The deaths occurred between June 2001 and February 2002.

PARTICIPANTS

Reporting physicians received a mailed questionnaire about the medical decision making that had preceded death. The response percentage was 75% for the Netherlands, 67% for Switzerland, 62% for Denmark, 61% for Sweden, 59% for Belgium, and 44% for Italy. The total number of deaths studied was 20,480.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Measurements were frequency of DNR decisions, both individual and institutional, and patient involvement. Before death, an individual DNR decision was made in about 50-60% of all nonsudden deaths (Switzerland 73%, Italy 16%). The frequency of institutional decisions was highest in Sweden (22%) and Italy (17%) and lowest in Belgium (5%). DNR decisions are discussed with competent patients in 10-84% of cases. In the Netherlands patient involvement rose from 53% in 1990 to 84% in 2001. In case of incompetent patients, physicians bypassed relatives in 5-37% of cases.

CONCLUSIONS

Except in Italy, DNR decisions are a common phenomenon in these six countries. Most of these decisions are individual, but institutional decisions occur frequently as well. In most countries, the involvement of patients in DNR decision making can be improved.

Levels of Care in the Intensive Care Unit: A Research Program

A multidisciplinary research program on levels of care was conducted in 15 adult intensive care units in North America, Europe, and Australia. The program addressed advance directives for cardiopulmonary resuscitation, provision of advanced life support, and clinicians’ discomfort with evolving treatment plans. The results indicated that the factors that determined the establishment of directives for advance life support differed from the factors that informed a decision to limit or withdraw support after admission to an intensive care unit. In addition, clinicians’ prognoses were imprecise and often an underestimation of the probability of short-term survival. Finally, some degree of discomfort was common in care providers in the intensive care unit, most often because they thought interventions were excessive and not compatible with an acceptable future quality of life. The provision of advanced life support mandates explicit decision making about how life-support measures should be used.

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.

Care at the end of life in critically ill patients: the European perspective

PURPOSE OF REVIEW

Care surrounding end-of-life has become a major topic in the intensive care medicine literature. Cultural and regional variations are associated with transatlantic debates about decisions to forego life-sustaining therapies and lead to recent international statements. The aim of this review is to provide insight into the decisions to forego life sustaining therapies and end-of-life care in Europe.

RECENT FINDINGS

Although decisions to forego life-sustaining therapies are increasingly made in European countries, frequency and characteristics of end-of-life care are still heterogeneous. Moreover, even though many determinants of these variations have been identified, epidemiologic and interventional studies still provide additional information. In agreement with public opinions, recent European laws have emphasized the patient's autonomy. In real life, advance care planning is rarely used. Decisions are often made by caregivers (physicians and nurses) or families, these latter being less involved than in North America. Not only ethic divergences between physicians but also cultural variations account for this disparity.

SUMMARY

To optimize end-of-life care in the intensive care unit, there is an urgent need for the development of palliative and multidisciplinary care in Europe. Furthermore, it highlights the need for culturally competent care, adapted to needs and values of every single patient and family. In addition, a lack of communication with families and within the medical team, an uninformed public about end-of-life issues, and insufficient training of intensive care unit staff are crucial barriers to end-of-life care development. Special awareness of professionals and innovative research are needed to promote a high-standard of end-of-life care in the intensive care unit.

Decision tools for life support: a review and policy analysis

OBJECTIVE

To identify, describe, and compare published documents intended to guide decisions about the administration, withholding, or withdrawal of life support in critical care.

DESIGN

Review article. SETTING AND SOURCES: Publicly available, English-language guidelines or decision tools for life support, identified through systematic literature search.

MEASUREMENTS AND MAIN RESULTS

Forty-nine documents were included and coded for authorship, source, development methodology, format, and positions taken on 12 common life-support issues. Sources were independent academics (n=21, 43%), professional organizations (n=19, 44%), and provider organizations. Eighteen documents (37%) described no development method. Twenty-three (47%) were produced collectively (e.g., by committees or consensus conference), 7 (14%) mentioned a literature review, and 2 (4%) were based upon the author's professional experience. Tools differed in format and focus; we characterize three types as decision schemas (involving clinical practice algorithms; n=7, 14%), decision guides (reviewing legal or professional positions; n=29, 59%), and decision counsels (more discursive and focusing typically on ethical issues; n=13, 27%). Tools addressed 12 common life-support issues: advance directives (67%), resource considerations (51%), ICU discharge criteria (27%), ICU admission criteria (16%), whether withholding differs from withdrawing life support (59%), whether nutrition and hydration decisions are different from decisions about other types of life support (61%), euthanasia (49%), double effect (47%), brain death (35%), special considerations for patients in a persistent vegetative state (51%), potential organ donors (12%), and pregnant patients (10%). Positions on these key life-support issues varied.

CONCLUSIONS

Published tools for guiding life-support decisions vary widely in their genesis, authorship, format, focus, and practicality. They also differ in their attention to, and positions on, key life-support dilemmas. Future research on decision tools should focus on how users interpret and apply the messages in these tools and their impacts on practice, quality of care, participant experiences, and outcomes.

In-hospital resource utilization during multiple casualty incidents

OBJECTIVE

To suggest guidelines for hospital organization during terror-related multiple casualty incidents (MCIs) based on the experience of 6 level I trauma centers.

SUMMARY BACKGROUND DATA

Most terror-related MCIs are bombings. The sporadic nature of these events complicates in-hospital preparation.

METHODS

Data were collected at all level I Trauma centers during/after MCIs for the Israel National Trauma registry. Patients were included if they were admitted or died in hospital following injury in suicide bombings (October 1, 2000 to June 30, 2003), which fulfilled Ministry of Health suggested criteria for MCIs (number of admissions, severity of injury).

RESULTS

Included were 325 casualties from 32 events, 34% of which had an Injury Severity Score >16. A third of the admissions arrived within 10 minutes and 65% within 30 minutes. Forty percent of the patients underwent CT scans directly from the ED. Operative procedures were performed on 60% of patients and 36% were transferred directly from the ED to the OR. Initiation of surgical procedures peaked at 1 to 1.5 hours, mainly multidisciplinary abdominal, thoracic, and vascular surgery. Orthopedic and plastic surgery predominated later. A third of the patients were admitted to ICUs, often (31%) directly from the ED.

CONCLUSIONS

High staffing demands for ED, OR, and ICU overlap. Anesthesiologists, general, thoracic, and vascular surgeons are in immediate demand. ICU admissions occur simultaneously with ongoing patient arrival to the ED. Most patients operated within the first 2 hours require multidisciplinary surgical teams. Demand for orthopedic and plastic surgery and anesthesiology services continues for >24 hours.

Withdrawing life-sustaining treatment: ethical considerations

In the community of caregivers, there is a general consensus that some heroic measures are not obligatory in certain circumstances that are defined by professional norms. For example, cardiopulmonary resuscitation in terminal cancer patients is not endorsed because of its violation of the dignity of the irremediably ill, and its unproductive cost to society. Moving back from this extreme, the availability and effectiveness of life-prolonging treatments, such as ventilators, dialysis, and implantable mechanical hearts, moves into a domain where the boundary limit of the obligation to preserve life is less clearly defined. When the continuing intervention of caregivers is essential to the prolongation of life, but the outcome and quality of residual life has deteriorated far below everyone's expectations when the treatment was initiated, caregivers are morally troubled as their treatments prolong the process of dying. Uncertainty or disputation about the prognosis raises the voltage of the fear and potential remorse that is a normal condition of care and support at the end of life. Unilateral decisions and overruling of objections should be avoided when possible, and reinforced by legal or ethical authorities when necessary. An ethics consultant, especially one skilled and experienced in management of end-of-life issues, can be a helpful negotiator and guide. The transition to palliative support should include the discontinuation of all unnecessary monitoring devices and tubes. Monitors should be turned off allowing families to direct their attention to the patient. Removing the monitor relieves family members from painful suspense and confusion. Removing the endotracheal tube sometimes allows conscious patients to talk to their loved ones, ending a silence forced on them by their treatment. If interventions are seen as masking the natural dying process, removing them should not be troubling. Their absence gives moral clarity to the elemental moments of closure at the end of life, no longer masked by futile contrivance. Withdrawal of life-sustaining treatment is a process that "merits the same meticulous preparation and expectation of quality that clinicians provide when they perform other procedures to initiate life support". Families and patients should never feel abandoned during this process and attention should be devoted to communicating that care is not being withdrawn. The family needs to be prepared for what the dying process may look like. Assure them that all energy is now being directed toward the comfort of the patient including sedation as required if signs of suffering are observed. Easing death, like easing birth, can be one of the most fulfilling contributions one can make to reduce the suffering and enrich the lives of patients and their families. Neglecting this part of the duty to provide appropriate care brings moral anguish to all participants in the peculiar circumstances that have come to surround death in the ICUs of developed countries. It is helpful to accept the inevitable reality that death is, in Shakespeare's words, a "necessary end" to all mortal life, and to recognize that defying death with technology can sometimes become an unnatural and degrading activity, however well motivated. The withdrawal of life-sustaining treatment, when conducted expertly, is a shared human experience that can be gratifying, although difficult for all concerned.

Nurse involvement in end-of-life decision making: the ETHICUS Study

OBJECTIVE

The purpose was to investigate physicians' perceptions of the role of European intensive care nurses in end-of-life decision making.

DESIGN

This study was part of a larger study sponsored by the Ethics Section of the European Society of Intensive Care Medicine, the ETHICUS Study. Physicians described whether they thought nurses were involved in such decisions, whether nurses initiated such a discussion and whether there was agreement between physicians and nurses. The items were analyzed and comparisons were made between different regions within Europe.

SETTING

The study took place in 37 intensive care units in 17 European countries.

PATIENTS AND PARTICIPANTS

Physician investigators reported data related to patients from 37 centers in 17 European countries.

INTERVENTIONS

None.

MEASUREMENTS AND RESULTS

Physicians perceived nurses as involved in 2,412 (78.3%) of the 3,086 end-of-life decisions (EOLD) made. Nurses were thought to initiate the discussion in 66 cases (2.1%), while ICU physicians were cited in 2,438 cases (79.3%), the primary physician in 328 cases (10.7%), the consulting physician in 105 cases (3.4%), the family in 119 cases (3.9%) and the patient in 19 cases (0.6%). In only 20 responses (0.6%) did physicians report disagreement between physicians and nurses related to EOLD. A significant association was found between the region and responses to the items related to nursing. Physicians in more northern regions reported more nurse involvement.

CONCLUSIONS

Physicians perceive nurses as involved to a large extent in EOLDs, but not as initiating the discussion. Once a decision is made, there is a sense of agreement. The level of perceived participation is different for different regions.

Striving for quality or length at the end-of-life: attitudes of the Dutch general public

Questionnaires were mailed to 1777 members of the Dutch public (response: 78%), measuring to what extent respondents appreciate life-prolonging treatment, even if it would seriously impair their quality of life. The association between these attitudes and personal characteristics and initiatives to engage in advance care planning was analyzed. About one third of the respondents prefers quality of life at the expense of survival, another third prefers length of life regardless of impaired quality, whereas the remaining third did not express a clear attitude towards quality or length of life. People who were younger, male, having children, having religious beliefs, and without a history of serious illness were more likely to strive for length, whereas the reverse associations were found for striving for quality. The latter was related to undertaking initiatives to engage in advance care planning. Awareness of differences in attitudes towards life-prolonging treatment within the public may improve communication about appropriate end-of-life care.

SAPS 3--From evaluation of the patient to evaluation of the intensive care unit. Part 1: Objectives, methods and cohort description

OBJECTIVE

Risk adjustment systems now in use were developed more than a decade ago and lack prognostic performance. Objective of the SAPS 3 study was to collect data about risk factors and outcomes in a heterogeneous cohort of intensive care unit (ICU) patients, in order to develop a new, improved model for risk adjustment.

DESIGN

Prospective multicentre, multinational cohort study.

PATIENTS AND SETTING

A total of 19,577 patients consecutively admitted to 307 ICUs from 14 October to 15 December 2002.

MEASUREMENTS AND RESULTS

Data were collected at ICU admission, on days 1, 2 and 3, and the last day of the ICU stay. Data included sociodemographics, chronic conditions, diagnostic information, physiological derangement at ICU admission, number and severity of organ dysfunctions, length of ICU and hospital stay, and vital status at ICU and hospital discharge. Data reliability was tested with use of kappa statistics and intraclass-correlation coefficients, which were >0.85 for the majority of variables. Completeness of the data was also satisfactory, with 1 [0-3] SAPS II parameter missing per patient. Prognostic performance of the SAPS II was poor, with significant differences between observed and expected mortality rates for the overall cohort and four (of seven) defined regions, and poor calibration for most tested subgroups.

CONCLUSIONS

The SAPS 3 study was able to provide a high-quality multinational database, reflecting heterogeneity of current ICU case-mix and typology. The poor performance of SAPS II in this cohort underscores the need for development of a new risk adjustment system for critically ill patients.

Communication of end-of-life decisions in European intensive care units

OBJECTIVE

To examine end-of-life (EOL) practices in European ICUs: who makes these decisions, how they are made, communication of these decisions and questions on communication between the physicians, nurses, patients and families.

DESIGN

Data collected prospectively on EOL decisions facilitated by a questionnaire including EOL decision categories, geographical regions, mental competency, information about patient wishes, and discussions with patients, families and health care professionals.

SETTING

37 European ICUs in 17 countries.

PATIENTS

ICU physicians collected data on 4,248 patients.

RESULTS

95% of patients lacked decision making capacity at the time of EOL decision and patient's wishes were known in only 20% of cases. EOL decisions were discussed with the family in 68% of cases. Physicians reported having more information about patients' wishes and discussions in the northern countries (31%, 88%) than central (16%, 70%) or southern (13%, 48%) countries. The family was more often told (88%) than asked (38%) about EOL decisions. Physicians' reasons for not discussing EOL care with the family included the fact that the patient was unresponsive to therapy (39%), the family was unavailable (28%), and the family was thought not to understand (25%).

CONCLUSIONS

ICU patients typically lack decision-making capacity, and physicians know patients' wishes in only 20% of EOL decisions. There were regional differences in discussions of EOL decisions with families and other physicians. In European ICUs there seems to be a need to improve communication.

Religious characteristics of U.S. physicians: a national survey

BACKGROUND

Patients' religious commitments and religious communities are known to influence their experiences of illness and their medical decisions. Physicians are also dynamic partners in the doctor-patient relationship, yet little is known about the religious characteristics of physicians or how physicians' religious commitments shape the clinical encounter.

OBJECTIVE

To provide a baseline description of physicians' religious characteristics, and to compare physicians' characteristics with those of the general U.S. population.

DESIGN/PARTICIPANTS

Mailed survey of a stratified random sample of 2,000 practicing U.S. physicians. Comparable U.S. population data are derived from the 1998 General Social Survey.

MEASUREMENTS/RESULTS

The response rate was 63%. Fifty-five percent of physicians say their religious beliefs influence their practice of medicine. Compared with the general population, physicians are more likely to be affiliated with religions that are underrepresented in the United States, less likely to say they try to carry their religious beliefs over into all other dealings in life (58% vs 73%), twice as likely to consider themselves spiritual but not religious (20% vs 9%), and twice as likely to cope with major problems in life without relying on God (61% vs 29%).

CONCLUSIONS

Physicians' religious characteristics are diverse and they differ in many ways from those of the general population. Researchers, medical educators, and policy makers should further examine the ways in which physicians' religious commitments shape their clinical engagements.

Differences in European critical care nursing practice: a pilot study

The purpose of this pilot study was to determine if there are differences in nursing practice between critical care units across Europe, if these practices are related to the perceived level of incorporation of evidence into nursing practice and/or to regional differences. Nurses attending the nursing session of the bi-annual conference of the European Society of Intensive Care Medicine were asked to fill out a two page questionnaire which addressed five areas of practice: physical care, pain management, monitoring, weaning and ethical issues. Some differences were found between regions although there were no differences in the perception of whether these protocols were evidence-based.

Older people's reasoning for resuscitation preferences and their role in the decision-making process

OBJECTIVES

To investigate older patients' reasoning for their cardiopulmonary resuscitation (CPR) preferences and the related decision-making process (DMP).

METHODS AND SUBJECTS

In a descriptive study 220 elderly home-dwelling cardiovascular patients were interviewed and asked to justify their CPR preferences according to the given statements. Questions related to DMP were asked and their physical function, cognition, mood, and quality of life were assessed.

RESULTS

Resuscitation preferences were associated with several patient characteristics, such as age, mood and quality of life. Patients preferring CPR (114/220, 52%) estimated their prognosis of CPR to be better than those preferring to forgo CPR. They justified their view: "Life is precious and worth living for me" (92%), "Maintaining life is a value of its own" (92%), "I feel needed by my family and my closest" (81%). Participants preferring to forgo CPR (106/220, 48%) justified: "I have already gained old age and led a full life" (88%), "People cannot decide these things" (72%). Only 9% of patients had discussed, and 38% would like to discuss preferences for life-sustaining treatments (LSTs) with their physician. However, 80% of respondents felt that the patients should take some part in the DMP; either alone (9%), together with a physician (23%), or together with a physician and a close relative (48%).

CONCLUSIONS

Older people justify their resuscitation preferences highlighting their experiences of meaningful life or fulfillment of their life, interpersonal relationships with their loved ones and presumed outcome of CPR. Less than a half of the patients wished to discuss CPR and LSTs preferences in their current situation with their physician, but nevertheless wanted to participate in the DMP of end-of-life treatment. Physicians should assess patients' own preferences in-depth.

Physicians’ attitudes towards end-of-life decisions: a comparison between seven countries

In the context of an European collaborative research project (EURELD), a study on attitudes towards medical end-of-life decisions was conducted among physicians in Belgium, Denmark, Italy, the Netherlands, Sweden and Switzerland. Australia also joined the consortium. A written questionnaire with structured questions was sent to practising physicians from specialties frequently involved in the care of dying patients. 10,139 questionnaires were studied. Response rate was equal to or larger than 50% in all countries except Italy (39%). Apart from general agreement with respect to the alleviation of pain and symptoms with possible life-shortening effect, there was large variation in support--between and within countries--for medical decision that may result in the hastening of death. A principal component factor analysis found that 58% of the variance of the responses is explained by four factors. 'Country' explained the largest part of the variation of the standardized factor scores.

Withholding and withdrawal of life-sustaining treatment in a Lebanese intensive care unit: a prospective observational study

OBJECTIVE

To evaluate the implementation and process of withholding and withdrawing life-sustaining treatment in an intensive care unit.

DESIGN AND SETTING

Prospective observational study in the medical intensive care unit of a university hospital in Lebanon.

PATIENTS

Forty-five consecutive adult patients admitted to the ICU for a 1-year period and for whom a decision to withholding and withdrawal of life-sustaining treatment was made.

MEASUREMENTS AND RESULTS

Patients were followed up until their death. Data regarding all aspects of the implementation and the process of withholding and withdrawal of life-sustaining treatment were recorded by a senior staff nurse. Withholding and withdrawing life-sustaining treatment was applied to 9.6% of all admitted patients to ICU. Therapies were withheld in 38% and were withdrawn in 7% of patients who died. Futility of care and poor quality of life were the two most important factors supporting these decisions. The nursing staff was not involved in 26% of the decisions to limit care. Families were not implicated in 21% of the cases. Decisions were not notified in the patients' medical record in 23% of the cases. Sixty-three percent of patients did not have a sedative or an analgesic to treat discomfort during end-of-life care.

CONCLUSIONS

Life-sustaining treatment were frequently withheld or withdrawn from adult patients in the Lebanese ICU. Cultural differences and the lack of guidelines and official statements could explain the ethical limitations of the decision-making process recorded in this study.

Withdrawing and withholding life-sustaining therapies are not the same

Numerous lines of evidence support the premise that withholding and withdrawing life support measures in the intensive care unit are not the same. These include questionnaires, practical observations and an examination of national medical guidelines. It is important to distinguish between the two end of life options as their outcomes and management are significantly different. Appreciation of these differences allows the provision of accurate information, and facilitates decision making that is compassionate, caring and adherent to the needs of the patient and their family.

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.
