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

Association between education in EOL care and variability in EOL practice: a survey of ICU physicians

PURPOSE

This study investigated the association between physician education in EOL and variability in EOL practice, as well as the differences between beliefs and practices regarding EOL in the ICU.

METHODS

Physicians from 11 ICUs at a university hospital completed a survey presenting a patient in a vegetative state with no family or advance directives. Questions addressed approaches to EOL care, as well physicians' personal, professional and EOL educational characteristics.

RESULTS

The response rate was 89%, with 105 questionnaires analyzed. Mean age was 38 ± 8 years, with a mean of 14 ± 7 years since graduation. Physicians who did not apply do-not-resuscitate (DNR) orders were less likely to have attended EOL classes than those who applied written DNR orders [0/7 vs. 31/47, OR = 0.549 (0.356-0.848), P = 0.001]. Physicians who involved nurses in the decision-making process were more likely to be ICU specialists [17/22 vs. 46/83, OR = 4.1959 (1.271-13.845), P = 0.013] than physicians who made such decisions among themselves or referred to ethical or judicial committees. Physicians who would apply "full code" had less often read about EOL [3/22 vs. 11/20, OR = 0.0939 (0.012-0.710), P = 0.012] and had less interest in discussing EOL [17/22 vs. 20/20, OR = 0.210 (0.122-0.361), P < 0.001], than physicians who would withdraw life-sustaining therapies. Forty-four percent of respondents would not do what they believed was best for their patient, with 98% of them believing a less aggressive attitude preferable. Legal concerns were the leading cause for this dichotomy.

CONCLUSIONS

Physician education about EOL is associated with variability in EOL decisions in the ICU. Moreover, actual practice may differ from what physicians believe is best for the patient.

Policies of withholding and withdrawal of life-sustaining treatment in critically ill patients on cardiac intensive care units in Germany: a national survey

OBJECTIVE

To determine the decision-making process of withholding and/or withdrawal (WH/WD) of life-sustaining treatment in cardiac intensive care units (ICUs) in Germany.

METHODS

A questionnaire regarding 16 medical and 6 ethical questions of WH/WD of life-sustaining treatment was distributed to the clinical director, senior ICU physician and head nurses of all German heart surgery centres (n = 237 questionnaires). Furthermore, we present a literature survey using the key words 'End-of-life care AND withholding/withdrawal of life support therapy AND intensive care unit'.

RESULTS

We received replies from 86 of 237 (36.3%) contacted persons. Concerning medical reasons, cranial computed tomography (CCT) with poor prognosis (91.9%), multi-organ failure (70.9%) and failure of assist device therapy (69.8%) were the three most frequently cited medical reasons for WH/WD life-sustaining treatment. Overall, 32.6% of persons answered that ethical aspects influence their decision-making processes. Poor expected quality of life (48.8%), the patient's willingness to limit medical care (40.7%) and the families' choice (27.9%) were the top three reported ethical reasons. There was a significant difference regarding the perception of the three involved professional groups concerning the decision-making parameters: multi-organ failure (P = 0.018), failure of assist device therapy (P = 0.001), cardiac index (P = 0.009), poor expected quality of life (P = 0.009), the patient's willingness to limit medical care (P = 0.002), intraoperative course (P = 0.054), opinion of family members (P = 0.032) and whether decision-making process are done collaboratively (clinical director, 45.7%; ICU physician, 52%; and head of nursing staff, 26.9%). Palliation medication in patients after WH/WD of life-support consisted of morphine (92%) and benzodiazepines (88%).

CONCLUSIONS

This survey is a step towards creating standards of end-of-life care in cardiac ICUs, which may contribute to build consensus and avoid conflicts among caregivers, patients and families at each step of the decision-making process.

[Preliminary experience with the introduction of life-sustaining treatment limitation in the electronic clinical record]

Life-sustaining treatment limitation (LSTL) is an increasingly common practice. However, its application is sometimes not clearly reflected in the clinical record-this giving rise to the adoption of measures that could have been avoided, including admission to the intensive care unit (ICU), with the suffering and economical costs this implies. One way to trace patients subjected to LSTL is through an electronic registry allowing identification at all times of these individuals, and of the therapies that have been restricted in each case. The Ethics Committee of our center has developed a tool allowing the identification of patients subjected to LSTL and of the level of intervention required, and offering the association of a patient comfort management protocol.

How nurses and physicians face ethical dilemmas--the Croatian experience

The aim of this study was to assess nurses' and physicians' ethical dilemmas in clinical practice. Nurses and physicians of the Clinical Hospital Centre Rijeka were surveyed (N=364). A questionnaire was used to identify recent ethical dilemma, primary ethical issue in the situation, satisfaction with the resolution, perceived usefulness of help, and usage of clinical ethics consultations in practice. Recent ethical dilemmas include professional conduct for nurses (8%), and near-the-end-of-life decisions for physicians (27%). The main ethical issue is limiting life-sustaining therapy (nurses 15%, physicians 24%) and euthanasia and physician-assisted suicide (nurses 16%, physicians 9%). The types of help available are similar for nurses and physicians: obtaining complete information about the patient (37% vs. 50%) and clarifying ethical issues (31% vs. 39%). Nurses and physicians experience similar ethical dilemmas in clinical practice. The usage of clinical ethics consultations is low. It is recommended that the individual and team consultations should be introduced in Croatian clinical ethics consultations services.

End-of-life decisions in Hungarian intensive care units

The awareness of local practice of end-of-life decisions in accordance with the law and ethical principles is essential for intensive care physicians in all countries. The first step for the required social dialogue is to investigate local practice. We performed the first Hungarian survey with the aim of better understanding local practice in end-of-life decisions in intensive care units. Questionnaires were sent out electronically to 743 members of the Hungarian Society of Anaesthesiology and Intensive Care. Respecting anonymity, we have statistically evaluated 103 replies (response rate 13.8%) and compared the results to data from other European countries. The results show that the practice of intensive care physicians in Hungary is rather paternalistic. Intensive care physicians generally make their decisions alone (3.75/5 points) without considering the opinion of the patient (2.57/5 points), the relatives (2.14/5 points) or other medical staff (2.37/5 points). Furthermore, they prefer not to start a form of treatment rather than to withdraw an ongoing one. Nevertheless, the frequency of end-of-life decisions (3 to 9% of intensive care unit patients) made in Hungarian intensive care units is less than in other European countries. End-of-life decisions are part of medical practice. Since the legal and ethical framework is unclear practice varies between locations and mostly depends on individual decisions rather than established protocols or guidance. For end-of-life decisions, self-determination must be supported and a dialogue must be established between lawmakers and physicians.

A national survey of Italian physicians' attitudes towards end-of-life decisions following the death of Eluana Englaro

BACKGROUND

Ethical issues regarding patient care have recently been raised in Italy by the case of Eluana Englaro, a 36-year-old woman who remained in a persistent vegetative state (PVS) for 17 years. There are no specific laws on the books in Italy regarding euthanasia and physician-assisted suicide. In November 2008, a controversial decision by the Italian Supreme Court granted the woman's father his wish to discontinue nutrition and hydration provided to her. Because of this historic decision, the authors carried out a survey of Italian physicians' beliefs regarding end-of-life practices.

METHODS

A questionnaire was e-mailed to 70,000 physicians working for the Italian Public Health System and University Medical Hospitals.

RESULTS

A total of 22,219 doctors responded to the questionnaire (32.3%), of whom 17,252 (77.6%) had some experience in treating PVS patients. Nearly 70% of responding doctors were aware of PVS diagnostic criteria; most of them (61%) considered tube feeding to be a medical therapy, and 66% of respondents believed that withdrawal of assisted nutrition and hydration (ANH) might be appropriate depending on the patient's wishes. Moreover, even though 50% of doctors surveyed were not in favor of euthanasia, a significant percentage (42%) did approve of it, while 8% of this sample was uncertain.

CONCLUSIONS

Italian doctors probably have the least experience in end-of-life decisions in Europe, therefore this national survey is a great chance to understand their authentic opinions regarding such remarkable issues. There is broad consensus that a clear legislative position regarding euthanasia and ANH is needed.

Attitudes towards ethical problems in critical care medicine: the Chinese perspective

INTRODUCTION

Critical care doctors are frequently faced with clinical problems that have important ethical and moral dimensions. While Western attitudes and practice are well documented, little is known of the attitudes or practice of Chinese critical care doctors.

METHODS

An anonymous, written, structured questionnaire survey was translated from previously reported ethical surveys used in Europe and Hong Kong. A snowball method was used to identify 534 potential participants from 21 regions in China.

RESULTS

A total of 315 (59%) valid responses were analysed. Most respondents (66%) reported that admission to an intensive care unit (ICU) was commonly limited by bed availability, but most (63%) would admit patients with a poor prognosis to ICU. Only 19% of respondents gave complete information to patients and family, with most providing individually adjusted information, based on prognosis and the recipient's educational level. Only 28% disclosed all details of an iatrogenic incident, despite 62% stating that they should. The use of do not resuscitate orders or limitation of life-sustaining therapy in terminally ill patients reported as uncommon and according to comparable reports, both are more common practice in Hong Kong or Europe. In contrast to European practices, doctors were more acquiescent to families in decision-making at the end of life.

CONCLUSIONS

A number of differences in ethical attitudes and related behaviour between Chinese, Hong Kong and European ICU doctors were documented. A likely explanation is differing cultural background, and doctors should be aware of likely expectations when treating patients from a different culture.

Attitudes towards end-of-life issues in disorders of consciousness: a European survey

Previous European surveys showed the support of healthcare professionals for treatment withdrawal [i.e., artificial nutrition and hydration (ANH) in chronic vegetative state (VS) patients]. The recent definition of minimally conscious state (MCS), and possibly research advances (e.g., functional neuroimaging), may have lead to uncertainty regarding potential residual perception and may have influenced opinions of healthcare professionals. The aim of the study was to update the end-of-life attitudes towards VS and to determine the end-of-life attitudes towards MCS. A 16-item questionnaire related to consciousness, pain and end-of-life issues in chronic (i.e., >1 year) VS and MCS and locked-in syndrome was distributed among attendants of medical and scientific conferences around Europe (n = 59). During a lecture, the items were explained orally to the attendants who needed to provide written yes/no responses. Chi-square tests and logistic regression analyses identified differences and associations for age, European region, religiosity, profession, and gender. We here report data on items concerning end-of-life issues on chronic VS and MCS. Responses were collected from 2,475 participants. For chronic VS (>1 year), 66% of healthcare professionals agreed to withdraw treatment and 82% wished not to be kept alive (P < 0.001). For chronic MCS (>1 year), less attendants agreed to withdraw treatment (28%, P < 0.001) and wished not to be kept alive (67%, P < 0.001). MCS was considered worse than VS for the patients in 54% and for their families in 42% of the sample. Respondents' opinions were associated with geographic region and religiosity. Our data show that end-of-life opinions differ for VS as compared to MCS. The introduction of the diagnostic criteria for MCS has not substantially changed the opinions on end-of-life issues on permanent VS. Additionally, the existing legal ambiguity around MCS may have influenced the audience to draw a line between expressing preferences for self versus others, by implicitly recognizing that the latter could be a step on the slippery slope to legalize euthanasia. Given the observed individual variability, we stress the importance of advance directives and identification of proxies when discussing end-of-life issues in patients with disorders of consciousness.

An empirical study of surrogates' preferred level of control over value-laden life support decisions in intensive care units

RATIONALE

Despite ongoing ethical debate concerning who should control decisions to discontinue life support for incapacitated, critically ill patients, the perspectives of surrogate decision makers are poorly understood.

OBJECTIVES

To determine (1) what degree of decisional authority surrogates prefer for value-sensitive life support decisions compared with more technical biomedical decisions, and (2) what predicts surrogates' preferences for more control over life support decisions.

METHODS

This was a prospective study of 230 surrogate decision makers for incapacitated, mechanically ventilated patients at high risk of death. Surrogates reported their preferred degree of decisional authority using the Degner Control Preferences Scale for two types of decisions: a value-sensitive decision about whether to discontinue life support and a decision regarding which antibiotic to prescribe for an infection.

MEASUREMENTS AND MAIN RESULTS

The majority of surrogates (55%, 127/230; 95% confidence interval, 49-62%) preferred to have final control over the value-sensitive life support decision; 40% (91/230) wished to share control equally with the physician; 5% (12/230) of surrogates wanted the physician to make the decision. Surrogates preferred significantly more control over the value-sensitive life support decision compared with the technical decision about choice of antibiotics (P < 0.0001). Factors independently associated with surrogates' preference for more control over the life support decision were: less trust in the intensive care unit physician, male sex, and non-Catholic religious affiliation.

CONCLUSIONS

Surrogates vary in their desire for decisional authority for value-sensitive life support decisions, but prefer substantially more authority for this type of decision compared with technical, medical judgments. Low trust in physicians is associated with surrogates preferring more control of life support decisions.

[Practice of treatment restriction in Hungarian intensive care units]

End of life decisions affect most of patients in intensive care units, thus, it is important to know both local and international practice in accordance with law and ethical principles for intensive care physicians.

AIM

To search for local customs of end of life decisions (withholding or withdrawing the therapy, shortening of the dying process), and to compare the data with the international literature.

METHODS

In 2007-2008 the first Hungarian survey was performed with the purpose to learn more about local practice of end of life decisions. Questionnaires were sent out electronically to 743 registered members of Hungarian Society of Anesthesiology and Intensive Care. Respecting anonymity, 103 replies were statistically evaluated (response rate was 13.8%) and compared with data from other European countries.

RESULTS

As expected, it turned out from replies that the practice of domestic intensive care physicians is very paternal and this is promoted by legal regulations that share a similar character. Intensive care physicians generally make their decisions alone (3.75/5 point) without respecting the opinion of the patient (2.57/5 point) the relatives (2.14/5 point) or other medical personnel (2.37/5 point). Furthermore, they prefer not to start a therapy rather than withdraw an ongoing treatment. Nevertheless, the frequency of end of life decisions (3-9% of ICU patients) is smaller than other European countries.

CONCLUSIONS

There is a need for the expansion of patients' right in our country. For end of life decisions, self determinations must be supported and a dialogue must be established between lawmakers and physicians, in order to improve the legal support of this medical practice.

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

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

Compliance with DNR policy in a tertiary care center in Saudi Arabia

INTRODUCTION

Do not resuscitate (DNR) is an important aspect of medical practice, although few studies from Arab Muslim countries address this issue. King Abdulaziz Medical City (KAMC), Saudi Arabia has a policy addressing all aspects of patient care at end of life.

OBJECTIVE

To assess compliance of physicians with the current DNR policy.

METHODS

A cohort study of data prospectively collected from 15/10/2008 through 15/01/2009 for patients where DNR was initiated. Patient charts were followed prospectively to observe DNR documentation completion. Data were analyzed in terms of frequencies and descriptive statistics, and the results expressed as percentages.

RESULTS

DNR was initiated in 65 patients referred to the intensive care unit (ICU): 46.2% females, 53.8% males; age range 19-93 years, mean ± standard deviation (SD) 66.1 ± 16.0 years. DNR was initiated by ICU physician in 80% of cases and by most responsible physician (MRP) in 20% of cases. There was a delay (of more than 48 h) in completing MRP signature in 8 patients (12.3%), and no signature at all by the MRP in 13 patients (20%). Documentation of discussion with the family was absent in 53.8% of cases.

CONCLUSIONS

ICU physicians have a role in initiating DNR. Mostly this issue is not addressed on admission. Documentation of DNR once initiated is still not up to the optimum level in 32.3% of cases, mainly due to MRP. Discussion with the patient's family was not well documented in the chart in more than half of cases.

[Perception of ethical attitudes of intensive care nurses on treatment limitation]

OBJECTIVE

Analyze the perception of intensive care nurses regarding the limitation of therapeutic efforts (LET).

METHOD

A 2-month cross-sectional, descriptive study carried out among Intensive Care nursing staff of our Hospital. An anonymous survey was used to assess the attitudes of intensive care nurses on LET.

RESULTS

Fifty-two nurses (86.6%), 57.7% women, with a working experience of 8.8±4.8 years and 17.7%, had some additional training in ethics. The decision not to hospitalize a patient whose short term quality of life is very poor changes when the patient's opinion is considered (36.5% vs 61.5%, p=0.008), a difference that is greater in male nurses without prior training in ethics. A total of 23.1% were not aware of the existence of agreed on guidelines on LET in the Service. A total of 17.3% consider that limiting treatment, either by not providing it or by withdrawing it, is a form of passive euthanasia, which would be an acceptable practice as opposed to euthanasia and 84.6% consider that administering a treatment is not the same as withdrawing it. Of those surveyed, 36.5% felt that the neither the nursing staff should not participate in the decision to limit treatment nor the patients (34.6%) nor family (23.1%).

CONCLUSIONS

Nursing is not aware of the importance it can have, along with the family and patient, in decision making in relationship to the limitation of the treatment of the critical patient, providing a humanizing and ethical view of the care.

End-of-life communication in the intensive care unit

OBJECTIVE

Because one in five Americans die in the intensive care unit (ICU), the potential role of palliative care is considerable. End-of-life (EOL) communication is essential for the implementation of ICU palliative care. The objective of this review was to summarize current research and recommendations for ICU EOL communication.

DESIGN

For this qualitative, critical review, we searched PubMed, Embase, Cochrane, Ovid Medline, Cinahl and Psychinfo databases for ICU EOL communication clinical trials, systematic reviews, consensus statements and expert opinions. We also hand searched pertinent bibliographies and cross-referenced known EOL ICU communication researchers.

RESULTS

Family-centered communication is a key component of implementing EOL ICU palliative care. The main forum for this is the family meeting, which is an essential platform for implementing shared decision making, e.g., transitioning from curative to EOL palliative goals of care. Better communication can improve patient outcomes such as reducing psychological trauma symptoms, depression and anxiety; shortening ICU length of stay; and improving the quality of death and dying. Communication strategies for EOL discussions focus on addressing family emotions empathically and discussing death and dying in an open and meaningful way. Central to this is viewing ICU EOL palliative care and withdrawal of life-extending treatment as predictable and not an unexpected emergency.

CONCLUSIONS

Because the ICU is now a well-established site for death, ICU physicians should be trained with EOL communication skills so as to facilitate palliative care more hospitably in this challenging setting. Patient/family outcomes are important ways of measuring the quality of ICU palliative care and EOL communication.

Physician beliefs and practice regarding end-of-life care in India

Background and Aims:

Physician beliefs and practices largely determine the withdrawal of life support in intensive care units. No information exists regarding beliefs regarding the withdrawal of life support among physicians in India.

Materials and Methods:

We performed a questionnaire at the NAPCON conference in Jaipur.

Results:

One hundred and twenty-two questionnaires were completed and returned. The majority of respondents did not apply do not resuscitate orders. Most physicians stated withdrawal of life support was not allowed or practiced at their institution. Thirty-five percent of physicians stated they performed life-support withdrawal. Barriers to good end-of-life care were primarily legal but also included hospital policy and social constraints.

Conclusions:

Pulmonary and critical care physicians in India have a lower rate of withdrawal of life support than western physicians. The reasons seem to be primarily legal and policy related. Culture and religion were not identified as barriers. Clarification of the legal and policy status of withdrawal of life support is needed

Characteristics of deaths in paediatric intensive care: a 10-year study

OBJECTIVE

To describe the patient mortality over a 10-year period in a paediatric intensive care unit (PICU) including patient demographics, length of stay, cause and mode of death and to compare these findings with pre-existing literature from the western world.

DESIGN

A retrospective chart review.

SETTING

A UK tertiary PICU.

PATIENTS

All children who died in the PICU over a 10-year period between 1 November 1997 and 31 October 2007 (n = 204).

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Data recorded for each patient included patient demographics, length of stay and cause of death according to the International Classification of Disease-10 classification, and mode of death. Mode of death was assigned for each patient by placement in one of four categories: (i) brain death (BD), (ii) managed withdrawal of life-sustaining medical therapy (MWLSMT), (iii) failed cardiopulmonary resuscitation (CPR) and (iv) limitation of treatment (LT). Over the study period, findings showed a median length of stay of 2 days (IQR 0-5 days), with a mortality rate of 5%. The most common mode of death was MWLSMT (n = 112, 54.9%) and this was consistent across the 10-year period. Linear regression analysis demonstrated no significant change in trend over the 10 years in each of the modes of death; BD (p = 0.84), MWLSMT (p = 0.88), CPR (p = 0.35) and LT (p = 0.67).

CONCLUSION

End-of-life care is an important facet of paediatric intensive nursing/medicine. Ten years on from the Royal College of Paediatrics and Child Health publication 'Withholding or withdrawing life sustaining treatment in children: A framework for practice', this study found managed withdrawal of MWLSMT to be the most commonly practised mode of death in a tertiary PICU, and this was consistent over the study period.

Critical care services in Ontario: a survey-based assessment of current and future resource needs

PURPOSE

In response to the challenges of an aging population and decreasing workforce, the provision of critical care services has been a target for quality and efficiency improvement efforts. Reliable data on available critical care resources is a necessary first step in informing these efforts. We sought to describe the availability of critical care resources, forecast the future requirement for the highest-level critical care beds and to determine the physician management models in critical care units in Ontario, Canada.

METHODS

In June 2006, self-administered questionnaires were mailed to the Chief Executive Officers of all acute care hospitals, identified through the Ontario government's hospital database. The questionnaire solicited information on the number and type of critical care units, number of beds, technological resources and management of each unit.

RESULTS

Responses were obtained from 174 (100%) hospitals, with 126 (73%) reporting one or more critical care units. We identified 213 critical care units in the province, representing 1789 critical care beds. Over half (59%) of these beds provided mechanical ventilation on a regular basis, representing a capacity of 14.9 critical care and 8.7 mechanically ventilated beds per 100,000 population. Sixty-three percent of units with capacity for mechanical ventilation involved an intensivist in admission and coordination of care. Based on current utilization, the demand for mechanically ventilated beds by 2026 is forecast to increase by 57% over levels available in 2006. Assuming 80% bed utilization, it is estimated that an additional 810 ventilated beds will be needed by 2026.

CONCLUSION

Current utilization suggests a substantial increase in the need for the highest-level critical care beds over the next two decades. Our findings also indicate that non-intensivists direct care decisions in a large number of responding units. Unless major investments are made, significant improvements in efficiency will be required to maintain future access to these services.

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.

Austrian validation and customization of the SAPS 3 Admission Score

OBJECTIVE

To test the prognostic performance of the SAPS 3 Admission Score in a regional cohort and to empirically test the need and feasibility of regional customization.

DESIGN

Prospective multicenter cohort study.

PATIENTS AND SETTING

Data on a total of 2,060 patients consecutively admitted to 22 intensive care units in Austria from October 2, 2006 to February 28, 2007.

MEASUREMENTS AND RESULTS

The database includes basic variables, SAPS 3, length-of-stay and outcome data. The original SAPS 3 Admission Score overestimated hospital mortality in Austrian intensive care patients through all strata of the severity-of-illness. This was true for both available equations, the General and the Central and Western Europe equation. For this reason a customized country-specific model was developed, using cross-validation techniques. This model showed excellent calibration and discrimination in the whole cohort (Hosmer-Lemeshow goodness-of-fit: H = 4.50, P = 0.922; C = 5.61, P = 0.847, aROC, 0.82) as well as in the various tested subgroups.

CONCLUSIONS

The SAPS 3 Admission Score's general equation can be seen as a framework for addressing the problem of outcome prediction in the general population of adult ICU patients. For benchmarking purposes, region-specific or country-specific equations seem to be necessary in order to compare ICUs on a similar level.

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.

End of life in the intensive care unit: knowledge and practice of clinicians from Karachi, Pakistan

BACKGROUND

With improvements in the care of critically ill, physicians are faced with obligations to provide quality end-of-life care. Barriers to this include inadequate understanding of the dying patient and withdrawal or limitation of care. The objectives of this study were to document the comprehensions of physicians and nurses regarding the recognition and practice of end-of-life care for critically ill patients placed on life support in the intensive care unit.

METHODS

This was a cross-sectional study carried out at three hospitals in Karachi. Chi-squared analysis and one-way ANOVA were used to compare differences in response between the groups.

RESULTS

One hundred and thirty-seven physicians and critical care nurses completed the survey. 'Brain death' was defined as an 'irreversible cessation of brainstem function' by 85% respondents, with 50% relying on specialty consultation. Withdrawal of life support is practised by 83.2%; physicians are more likely (Chi square test P-value < 0.001) to withdraw mechanical ventilation, compared with nurses who would withdraw vasopressors (P-value 0.006). In a do not resuscitate patient, 72.3% use vasopressors, 83% initiate haemodialysis and 17.5% use non-invasive ventilation; 72.6% consult Hospital Ethics Committees; 16% respondents never withdraw life support; 28.3% considered it their responsibility to 'sustain life at all costs' and only 8% gave religious beliefs as a reason.

CONCLUSIONS

There are confusions in the definition of brain death, end-of-life recognition and indications and processes of withdrawal of life support. There are discrepancies between physicians' and nurses' perceptions and attitudes. Clearly, teaching programmes will need to incorporate cultural and religious differences in their ethics curricula.

A five-step protocol for withholding and withdrawing of life support in an emergency department: an observational study

OBJECTIVE

The objective of the study was to describe a five-step protocol for withholding and withdrawing of life support (WH/WDLS) in an emergency department (ED) for terminally ill patients.

DESIGN AND SETTING

An observational study was conducted in ED of a general hospital.

PATIENTS

A total of 98 patients were admitted over a 1-year period.

INTERVENTIONS

The healthcare team chose a pattern of treatment limitation on the basis of a five-step protocol for every patient, which comprised five groups: group 1: there was no limitation of care, group 2: do not resuscitate order was followed, group 3: administration of therapies without treating an acute organ failure, group 4: active withdrawal of all therapies except mechanical ventilation and group 5: active withdrawal of mechanical ventilation. All the patients received comfort care. The opinions of the patients and their families were collected.

MEASUREMENTS AND RESULTS

Ninety-eight patients were included in the study (1.5% of admissions). Mean age was 82+/-13 years. An acute organ failure was observed at admission in 80 patients. Severe chronic disease was noted in 93 patients. Among the 98 patients, there were 14 patients in group 2, 65 in group 3, six in group 4 and 13 in group 5. The time interval between admission and WH/WDLS decision was 117+/-77 min and ED stay was 239+/-136 min. The outcome was death in ED (n=21), admission to a medical ward (n=71) or an intensive care unit (n=six). On day 30, 16 patients were still alive.

CONCLUSION

This five-step protocol could improve collaboration in the WH/WDLS decision-making process, while facilitating dialogue and transmission of information between staff and families.

Factors related to the involvement of nurses in medical end-of-life decisions in Belgium: A death certificate study

BACKGROUND

Although nurses play an important role in end-of-life care for patients, they are not systematically involved in end-of-life decisions with a possible or certain life-shortening effect (ELDs). Until now we know little about factors relating to the involvement of nurses in these decisions.

OBJECTIVE

To explore which patient- and decision-characteristics are related to the consultation of nurses and to the administering of life-ending drugs by nurses in actual ELDs in institutions and home care, as reported by physicians.

METHOD

We sampled at random 5005 of all registered deaths in the second half of 2001--before euthanasia was legalized--in Flanders, Belgium. We mailed anonymous questionnaires to physicians who signed the death certificates and asked them to report on ELDs, including nurses' involvement.

RESULTS

Response rate was 59% (n=2950). Physicians reported nurses involved in decision making more often in institutions than at home, and more often in care homes for the elderly than in hospitals (OR 1.70, 95% CI 1.15, 2.52). This involvement was more frequently when physicians intended to hasten the patient's death than when they had no such intention (institutions: OR 2.05, 95% CI 1.41, 2.99; home: OR 2.04, 95% CI 1.19, 3.49). In institutions, this involvement was also more likely where patients were of lower rather than higher education (OR 2.95, 95% CI 1.49, 5.84). The administering of life-ending drugs by nurses, as reported by physicians was also found more frequently in institutions than at home, and in institutions more frequently with lower rather than higher educated patients (p=.037).

CONCLUSIONS

These findings raise questions about physicians' perception of the nurse's role in ELDs, but also about physicians' skills in interacting with all patients. Education and guidelines for physicians and nurses are needed to optimize good communication and to promote a clearer assignment of responsibilities concerning the execution of those decisions.

Cesarean delivery on maternal request: can the ethical problem be solved by the principlist approach?

In this article, we use the principlist approach to identify, analyse and attempt to solve the ethical problem raised by a pregnant woman's request for cesarean delivery in absence of medical indications. We use two different types of premises: factual (facts about cesarean delivery and specifically attitudes of obstetricians as derived from the EUROBS European study) and value premises (principles of beneficence and non-maleficence, respect for autonomy and justice).Beneficence/non-maleficence entails physicians' responsibility to minimise harms and maximise benefits. Avoiding its inherent risks makes a prima facie case against cesarean section without medical indication. However, as vaginal delivery can have unintended consequences, there is a need to balance the somewhat dissimilar risks and benefits. The principle of autonomy poses a challenge in case of disagreement between the pregnant woman and the physician. Improved communication aimed to enable better informed choice may overcome some instances of disagreement. The principle of justice prohibits unfair discrimination, and broadly favours optimising resource utilisation. Available evidence supports vaginal birth in uncomplicated term pregnancies as the standard of care. The principlist approach offered a useful framework for ethical analysis of cesarean delivery on maternal request, identified the rights and duties of those involved, and helped reach a conclusion, although conflict at the individual level may remain challenging.

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.

Meeting physicians' responsibilities in providing end-of-life care

Despite many clinical examples of exemplary end-of-life care, a number of studies highlight significant shortcomings in the quality of end-of-life care that the majority of patients receive. In part, this stems from inconsistencies in training and supporting clinicians in delivering end-of-life care. This review describes the responsibilities of pulmonary and critical care physicians in providing end-of-life care to patients and their families. While many responsibilities are common to all physicians who care for patients with life-limiting illness, some issues are particularly relevant to pulmonary and critical care physicians. These issues include prognostication and decision making about goals of care, challenges and approaches to communicating with patients and their family, the role of interdisciplinary collaboration, principles and practice of withholding and withdrawing life-sustaining measures, and cultural competency in end-of-life care.

How decisions are made to admit patients to medical intensive care units (MICUs): a survey of MICU directors at academic medical centers across the United States

OBJECTIVE

To determine how medical intensive care unit (MICU) admission decisions are made at U.S. academic MICUs and to learn how these practices compare with the recommendations of the Society of Critical Care Medicine and the American Thoracic Society.

DESIGN

A 22-question Web-based survey.

SETTING

University health sciences centers.

SUBJECTS

MICU directors at academic U.S. medical centers offering fellowship programs in pulmonary/critical care or critical care medicine.

INTERVENTIONS

The survey was sent by E-mail to 146 academic MICU directors.

MEASUREMENTS AND MAIN RESULTS

Survey response rate was 83% (121/146). MICU attendings were the primary decision-maker for patient admission to the intensive care unit (ICU) in 40% of the MICUs during daytime hours, in 36% on weekends, and in 27% overnight. Critical care fellows and resident house staff were often responsible for making MICU admission decisions, particularly overnight and on weekends. Of the MICUs surveyed, 88% had written admission guidelines, although only 25% used them on a regular basis. Written restriction guidelines were present in only 21% of these ICUs, although 53% of MICU directors believed that MICUs should have standardized criteria for restricting admission to the ICU. Finally, 29% of MICUs surveyed did not authorize MICU attendings to deny ICU admission on a case-by-case basis for futile or inadvisable care, thereby maintaining an open door policy for ICU admission.

CONCLUSIONS

Significant practice variability exists across U.S. academic MICUs regarding how decisions are made to admit patients to the ICU. The majority of academic MICUs in the United States do not strictly employ ICU admission and restriction guidelines, as recommended by the Society of Critical Care Medicine and the American Thoracic Society.

Withholding and withdrawing life-sustaining treatment: a comparative study of the ethical reasoning of physicians and the general public

Background

Our objective was to investigate whether a consensus exists between the general public and health care providers regarding the reasoning and values at stake on the subject of life-sustaining treatment.

Methods

A postal questionnaire was sent to a random sample of members of the adult population (n = 989) and to a random sample of intensive care doctors and neurosurgeons (n = 410) practicing in Sweden in 2004. The questionnaire was based on a case involving a severely ill patient and presented arguments for and against withholding and withdrawing treatment, and providing treatment that might hasten death.

Results

Approximately 70% of the physicians and 51% of the general public responded. A majority of doctors (82.3%) stated that they would withhold treatment, whereas a minority of the general public (40.2%) would do so; the arguments forwarded (for instance, belief that the first task of health care is to save life) and considerations regarding quality of life differed significantly between the two groups. Most physicians (94.1%) and members of the general public (77.7%) were prepared to withdraw treatment, and most (95.1% of physicians and 82% of members of the general public) agreed that sedation should be provided.

Conclusion

There are indeed considerable differences in how physicians and the general public assess and reason in critical care situations, but the more hopelessly ill the patient became the more the groups' assessments tended to converge, although they prioritized different arguments. In order to avoid unnecessary dispute and miscommunication, it is important that health care providers be aware of the public's views, expectations, and preferences.

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.
