End-of-life decisions in ICU and cultural specifities

Pattern of end-of-life decisions in two Tunisian intensive care units: the role of culture and intensivists' training

PURPOSE

End-of-life (EOL) decisions are not well studied in developing countries. We report EOL decision patterns in two Tunisian intensive care units [ICUs, medical (MICU) and surgical (SICU)] belonging to the same teaching hospital.

METHODS

Consecutive deaths that occurred in participating ICUs over 2 years were analysed. End-of-life decisions were prospectively recorded by the senior attending physicians, while subject's characteristics were retrospectively collected.

RESULTS

Deaths occurred in 326 of 1,733 ICU-admitted patients (median age: 64 years; median SAPS II at admission = 36). Overall, a decision for full support was taken in 69%, while decisions to withhold or withdraw life support were held in 22.1 and 8.9% of deaths, respectively. The rate of end-of-life decisions was similar in the MICU and the SICU. In no instance was there MV withdrawal during ICU stay. Discharging patients to die at home was observed only in the MICU (10 out of the 20 patients with a withdrawal decision). Two factors were independently associated with WH or WD decisions: a severe and ultimately fatal underlying disease was positively associated with such decisions (OR = 2.4, 95% CI: 1.3-4.36; p = 0.003), while having an independent functional status before the ICU was associated with a decreased rate of physician decisions of WH or WD (OR = 0.32, 95% CI: 0.15-0.67; p = 0.002).

CONCLUSION

Withholding and withdrawing life support are common in medical and surgical ICUs of a Tunisian hospital. Withholding is more frequent than withdrawing life support. These decisions appear to be effected by functional status and underlying conditions.

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.

Value choices and considerations when limiting intensive care treatment: a qualitative study

BACKGROUND

To shed light on the values and considerations that affect the decision-making processes and the decisions to limit intensive care treatment.

METHOD

Qualitative methodology with participant observation and in-depth interviews, with an emphasis on eliciting the underlying rationale of the clinicians' actions and choices when limiting treatment.

RESULTS

Informants perceived over-treatment in intensive care medicine as a dilemma. One explanation was that the decision-making base was somewhat uncertain, complex and difficult. The informants claimed that those responsible for taking decisions from the admitting ward prolonged futile treatment because they may bear guilt or responsibility for something that had gone wrong during the course of treatment. The assessments of the patient's situation made by physicians from the admitting ward were often more organ-oriented and the expectations were less realistic than those of clinicians in the intensive care unit who frequently had a more balanced and overall perspective. Aspects such as the personality and the speciality of those involved, the culture of the unit and the degree of interdisciplinary cooperation were important issues in the decision-making processes.

CONCLUSION

Under-communicated considerations jeopardise the principle of equal treatment. If intensive care patients are to be ensured equal treatment, strategies for interdisciplinary, transparent and appropriate decision-making processes must be developed in which open and hidden values are rendered visible, power structures disclosed, employees respected and the various perspectives of the treatment given their legitimate place.

Bioethical aspects of end-of-life care

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

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 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.
