End-of-life decisions in adult intensive care: current research base 158 and directions for the future

End-of-life decisions and practices as viewed by health professionals in pediatric critical care: A European survey study

BACKGROUND AND AIM

End-of-Life (EOL) decision-making in paediatric critical care can be complex and heterogeneous, reflecting national culture and law as well as the relative resources provided for healthcare. This study aimed to identify similarities and differences in the experiences and attitudes of European paediatric intensive care doctors, nurses and allied health professionals about end-of-life decision-making and care.

METHODS

This was a cross-sectional observational study in which we distributed an electronic survey to the European Society of Paediatric and Neonatal Intensive Care (ESPNIC) members by email and social media. The survey had three sections: (i) 16 items about attitudes to EOL care, (ii) 14 items about EOL decisions, and (iii) 18 items about EOL care in practice. We used a 5-point Likert scale and performed descriptive statistical analysis.

RESULTS

Overall, 198 questionnaires were completed by physicians (62%), nurses (34%) and allied health professionals (4%). Nurses reported less active involvement in decision-making processes than doctors (64% vs. 95%; p < 0.001). As viewed by the child and family, the child's expected future quality of life was recognised as one of the most critical considerations in EOL decision-making. Sub-analysis of Northern, Central and Southern European regions revealed differences in the optimal timing of EOL decisions. Most respondents (n = 179; 90%) supported discussing organ donation with parents during EOL planning. In the sub-region analysis, differences were observed in the provision of deep sedation and nutritional support during EOL care.

CONCLUSIONS

This study has shown similar attitudes and experiences of EOL care among paediatric critical care professionals within European regions, but differences persist between European regions. Nurses are less involved in EOL decision-making than physicians. Further research should identify the key cultural, religious, legal and resource differences underlying these discrepancies. We recommend multi-professional ethics education to improve EOL care in European Paediatric Intensive Care.

Nurses’ and Physicians’ Opinions on Aggressiveness of Treatment for General Ward Patients

The aim of this study was to evaluate agreement between nurses’ and physicians’ opinions regarding aggressiveness of treatment and to investigate and compare the rationales on which their opinions were based. Structured interviews regarding 714 patients were performed on seven general wards of a university hospital. The data gathered were then subjected to qualitative and quantitative analyses. There was 86% agreement between nurses’ and physicians’ opinions regarding full or limited treatment when the answers given as ‘uncertain’ were excluded. Agreement was less (77%) for patients with a life expectancy of less than one year. Disagreements were not associated with professional status because the physicians considered limiting life-sustaining treatment as often as the nurses. A broad spectrum of rationales was given but the results focus mostly on those for full treatment. The nurses and the physicians had similar bases for their opinions. For the majority of the patients, medical rationales were used, but age and quality of life were also expressed as important determinants. When considering full treatment, nurses used quality-of-life rationales for significantly more patients than the physicians. Respect for patients’ wishes had a minor influence.

Perspectives of physicians and nurses regarding end-of-life care in the intensive care unit

CONTEXT

The delivery of end-of-life care (EOLC) in the intensive care unit (ICU) varies widely among medical care providers. The differing opinions of nurses and physicians regarding EOLC may help identify areas of improvement.

OBJECTIVE

To explore the differences of physicians and nurses on EOLC in the ICU and how these differences vary according to self-reported proficiency level and primary work unit.

DESIGN

Cross-sectional survey of 69 ICU physicians and 629 ICU nurses.

SETTING

Single tertiary care academic medical institution.

RESULTS

A total of 50 physicians (72%) and 331 nurses (53%) participated in the survey. Significant differences between physicians and nurses were noted in the following areas: ability to safely raise concerns, do not resuscitate (DNR) decision making, discussion of health care directives, timely hospice referral, spiritual assessment documentation, utilization of social services, and the availability of EOLC education. In every domain of EOLC, physicians reported a more positive perception than nurses. Additional differences were noted among physicians based on experience, as well as among nurses based on their primary work unit and self-reported proficiency level.

CONCLUSIONS

Even with an increased focus on improving EOLC, significant differences continue to exist between the perspectives of nurses and physicians, as well as physicians among themselves and nurses among themselves. These differences may represent significant barriers toward providing comprehensive, consistent, and coordinated EOLC in the ICU.

Nurses' perceptions of end-of-life care after multiple interventions for improvement

BACKGROUND

Nurses working in intensive care units may lack knowledge and skills in end-of-life care, find caring for dying patients and the patients' families stressful, and lack support to provide this care.

OBJECTIVES

To describe nurses' perceptions of (1) knowledge and ability, (2) work environment, (3) support for staff, (4) support for patients and patients' families, and (5) stress related to specific work situations in the context of end-of-life care before (phase 1) and after (phase 2) implementation of approaches to improve end-of-life care. The approaches were a nurse-developed bereavement program for patients' families, use of a palliative medicine and comfort care team, preprinted orders for the withdrawal of life-sustaining treatment, hiring of a mental health clinical nurse specialist, and staff education in end-of-life care.

METHODS

Nurses in 4 intensive care units at a university medical center reported their perceptions of end-of-life care by using a 5-subscale tool consisting of 30 items scored on a 4-point Likert scale. The tool was completed by 91 nurses in phase 1 and 127 in phase 2.

RESULTS

Improvements in overall mean scores on the 5 sub-scales indicated that the approaches succeeded in improving nurses' perceptions. In phase 2, most of the subscale overall mean scores were higher than a desired criterion (<2.0, good). Analysis of variance indicated that some improvements occurred over time differently in the units; other improvements occurred uniformly.

CONCLUSIONS

Continued practice development is needed in end-of-life care issues.

Metasynthesis: withdrawing life-sustaining treatments: the experience of family decision-makers

AIM

The present study was undertaken to synthesise findings from qualitative investigations of family participation in decisions to withdraw and/or withhold life-sustaining treatment from a seriously ill family member.

BACKGROUND

As a consequence of increasing effectiveness and sophistication of available medical interventions, death is commonly preceded by a decision to withdraw or withhold potentially life-sustaining treatments. These decisions take place in a bioethical context characterised by the pre-eminence of self-determination, but patients are typically too ill to make their own decisions. Thus, family members are called upon to participate in these morally consequential decisions on the patient's behalf.

DESIGN

Metasynthesis.

METHOD

Metasynthesis is a form of inquiry that provides for integration of qualitative studies' findings to strengthen knowledge for practice and advance theoretical development. This metasynthesis was conducted using the constant comparative methods of grounded theory.

RESULTS

Family members engage in a process of participation in decision-making that is comprised of three major categories: reframing reality, relating and integrating. Surrogates used both cues and information as they reframed their understanding of the patient's status. Relationships with providers and with other family members powerfully influenced the decision-making process. Integrating was characterised by reconciling and going forward. This part of the process has both intrapersonal and interpersonal aspects and describes how family decision-makers find meaning in their experience and move forward in their lives.

CONCLUSIONS

This synthesis provides a more comprehensive and empirically supported understanding of family members' experiences as they participate in treatment decisions for dying family members. Relevance to clinical practice. This metasynthesis provides evidence to improve family care during treatment withdrawal/withholding decision-making and a theoretical model that can be used to guide creation of clinical practice guidelines. Through increased understanding of family members' experiences, clinicians can more effectively support family decision-making processes.

Barriers to intensive care unit nurses providing terminal care: an integrated literature review

Traditional goals of critical care center on curative interventions for patients with acute illness. However, death is a common occurrence in critical care, which means a shift from curative care to comfort care. For a number of reasons, the transition in care is often not a smooth one. An integrated literature review was completed on 22 studies related to provision of terminal care. These 13 quantitative studies along with 9 qualitative studies identified specific barriers to effective terminal care provision including (a) lack of involvement in the plan of care and comfort, (b) disagreement among physicians and other healthcare team members, (c) inadequacy of pain relief, (d) unrealistic expectations of families, (e) nurses' difficulty coping, (f) lack of experience and education, (g) staffing levels, and (h) environmental circumstances. Recommendations address strategies to improve terminal care and suggest future research needed.

Patient involvement in health-related decisions during prolonged critical illness

We describe patterns of communication of patients involved in health-related decision making during prolonged mechanical ventilation (PMV). Data were collected using observation, interview, and record review. Twelve of 30 patients participated in decisions about initiating, withdrawing, and withholding life-sustaining treatment, surgery, artificial feeding, financial/legal issues, discharge care, and daily care procedures. Patient involvement was largely validation or confirmation of what clinicians and families had already decided. Patients' participation was enlisted by clinicians and family members even when the patients did not exhibit full decisional capacity. Patient involvement in health-related decisions during prolonged critical illness is a shared and negotiated process that requires continued empirical study and ethical analysis.

The process used by surrogate decision makers to withhold and withdraw life-sustaining measures in an intensive care environment

PURPOSE/OBJECTIVES

To understand the process used by surrogate decision makers who have chosen to withhold and withdraw life-sustaining measures in intensive care units (ICUs).

DESIGN

Grounded theory.

SETTING

Multihospital system in central Texas.

SAMPLE

17 surrogates who decided to withhold and withdraw life-sustaining measures from patients with a variety of diagnoses, including cancer.

METHODS

Surrogates were identified by review of charts of patients in ICUs. Interviews were recorded on audiotape and analyzed using the process of constant comparison. Saturation of data occurred when no new themes emerged.

MAIN RESEARCH VARIABLE

The surrogate decision-making process.

FINDINGS

Domains and their respective themes included: (a) the personal domain: rallying family support, evaluating the patient's past and present condition, and viewing past and future quality of life; (b) the ICU environment domain: chasing doctors, developing relationships with the healthcare team, and confirming probable medical outcomes; and (c) the decision domain: arriving at a new belief, getting alone to make the decision, and communicating the decision.

CONCLUSIONS

Surrogates use a definite process to make decisions regarding withholding and withdrawing life-sustaining measures for patients in ICUs.

IMPLICATIONS FOR NURSING

The results reveal opportunities for healthcare providers to improve education and change practice when supporting surrogates. Additional opportunities exist for further research to expand nursing knowledge related to end-of-life issues.

The neuroscience ICU nurse's perceptions about end-of-life care

The purpose of this qualitative descriptive study was to describe neuroscience intensive care unit (NICU) nurses' perceptions regarding their roles and responsibilities in the decision-making process during the change in intensity of care and end-of-life care for patients. Twelve NICU nurses agreed to a private moderately structured interview. Three major themes summarize the data: (1) providing guidance, (2) being positioned in the middle of the communication process, and (3) feeling the emotions of patients and families. The nurse caring for a patient at the end of life provides guidance from the middle or "hub" of the communication process between family members and physicians. The nurses in this study describe an array of feelings associated with this role. This research adds to the limited body of knowledge concerning critical care nurses' experiences with end-of-life care. Providing guidance and being in the middle of the communication process can be a lonely, challenging, yet rewarding position. Results of this study provide a basis for offering emotional support to NICU nurses who care for patients at the end of life.

Proactive palliative care in the medical intensive care unit: effects on length of stay for selected high-risk patients

OBJECTIVE

The purpose of this study was to examine the effect of proactive palliative care consultation on length of stay for high-risk patients in the medical intensive care unit (MICU).

DESIGN

A prospective pre/post nonequivalent control group design was used for this performance improvement study.

SETTING

Seventeen-bed adult MICU.

PATIENTS

Of admissions to the MICU, 191 patients were identified as having a serious illness and at high risk of dying: 65 patients in the usual care phase and 126 patients in the proactive palliative care phase. To be included in the sample, a patient had to meet one of the following criteria: a) intensive care admission following a current hospital stay of >or=10 days; b) age >80 yrs in the presence of two or more life-threatening comorbidities (e.g., end-stage renal disease, severe congestive heart failure); c) diagnosis of an active stage IV malignancy; d) status post cardiac arrest; or e) diagnosis of an intracerebral hemorrhage requiring mechanical ventilation.

INTERVENTIONS

Palliative care consultations.

MEASUREMENTS AND MAIN RESULTS

Primary measures were patient lengths of stay a) for the entire hospitalization; b) in the MICU; and c) from MICU admission to hospital discharge. Secondary measures included mortality rates and discharge disposition. There were no significant differences between the usual care and proactive palliative care intervention groups in respect to age, gender, race, screening criteria, discharge disposition, or mortality. Patients in the proactive palliative care group had significantly shorter lengths of stay in the MICU (8.96 vs. 16.28 days, p = .0001). There were no differences between the two groups on total length of stay in the hospital or length of stay from MICU admission to hospital discharge.

CONCLUSIONS

Proactive palliative care consultation was associated with a significantly shorter MICU length of stay in this high-risk group without any significant differences in mortality rates or discharge disposition.

Communication between physicians and nurses as a target for improving end-of-life care in the intensive care unit: Challenges and opportunities for moving forward

Our objective was to discuss obstacles and barriers to effective communication and collaboration regarding end-of-life issues between intensive care unit nurses and physicians. To evaluate practical interventions for improving communication and collaboration, we undertook a systematic literature review. An increase in shared decision making can result from a better understanding and respect for the perspectives and burdens felt by other caregivers. Intensive care unit nurses value their contributions to end-of-life decision making and want to have a more active role. Increased collaboration and communication can result in more appropriate care and increased physician/nurse, patient, and family satisfaction. Recommendations for improvement in communication between intensive care unit physicians and nurses include use of joint grand rounds, patient care seminars, and interprofessional dialogues. Communication interventions such as use of daily rounds forms, communication training, and a collaborative practice model have shown positive results. When communication is clear and constructive and practice is truly collaborative, the end-of-life care provided to intensive care unit patients and families by satisfied and engaged professionals will improve markedly.

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.

Randomized study of stability and change in patients' advance directives

Little is known about ethnic differences in understanding or using advance directives (ADs). Although health practitioners may presume AD intentions are durable over time, there is no supporting evidence. This randomized study intended to (a) examine differences between hospitalized Hispanic and non-Hispanic patients' AD preferences, (b) assess AD stability, and (c) discover if the Life Support Preferences Questionnaire (LSPQ) influences AD preferences. Hispanics and non-Hispanics showed no difference in AD preferences. However, non-Hispanics were more likely to change AD preferences. The LSPQ itself prompted change in AD preferences, delivering an educational effect with no specific educational intent. Change seen in patients' ADs, even over a brief interval, suggests revisiting AD preferences with patients and their families after hospitalization.

Medical Care at the End of Life: Views of African American Patients in an Urban Hospital

BACKGROUND

Although one goal of end-of-life care is to honor the wishes and needs of patients, little research has been done to characterize what is important to seriously ill African American patients at the end of life.

OBJECTIVE

To characterize the views of seriously ill African American patients toward end-of- life care.

DESIGN

A qualitative study using semistructured, in-depth interviews.

SETTING AND PARTICIPANTS

Patients in a large, urban, public hospital who are facing a serious illness.

RESULTS

Twenty-three African American patients were interviewed. Although most acknowledged a point at which they would want to cease aggressive care, some equated this with giving up. Most subjects expressed that the end of life was in God's hands. Many expressed a concern to be free of pain and suffering. Few saw a significant role for the physician at the end of life. Some had expressed their wishes for care to a family member. Others thought such discussions were unnecessary because a family member would make decisions or because death was not imminent. Subjects raised concerns about trust in the physician and the burden of end-of-life discussions.

CONCLUSIONS

African Americans in an urban, public hospital who are facing a severe illness have clear desires for care at the end of life and are willing to discuss their views at length. Such discussions should explore patients' desire for aggressive care, consider spiritual views and the importance of family in end-of-life decisions, and consider that some patients will not believe such discussions are necessary.

Caring for the family of the critically ill patient

Family's needs and considerations are an essential component of intensive care unit (ICU) care. Family satisfaction is related to clinician communication and decision making. Indeed, timely, honest communication is vital to the psychosocial health and satisfaction of the family. Conflict often arises within the family and between the family and the clinicians, over decision making. Again, good communication skills are critical to family satisfaction with decision making and comfort with the care received. Family members have numerous psychosocial changes, and may experience depression,anxiety, or anticipatory grief while their family member is dying in the ICU. Awareness of these conditions, providing support to the families, and allowing family access to the dying individual can assist with meeting the family's desire to see their family member have a peaceful death.

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

OBJECTIVE

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

DESIGN

Qualitative interview that applies a phenomenological approach.

SETTING

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

PARTICIPANTS

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

RESULTS

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

CONCLUSION

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

The role of the critical care nurse in the assessment and management of the patient with severe sepsis

Sepsis with acute organ dysfunction is common, frequently fatal, and expensive. The critical care nurse is involved in the continuous bedside care of the critically ill patient; consequently, he or she has the opportunity to prevent sepsis through infection control practices and general nursing care, to identify patients at risk for the disease, to monitor these patients for the clinical signs of sepsis, and to detect developing organ dysfunction as a manifestation of severe sepsis. In addition, the nurse is responsible for monitoring the patient's response to organ support measures and specific antisepsis interventions. The role of the critical care nurse in the assessment and management of severe sepsis is significant and can greatly improve outcomes for the patient with this disease. Drotrecogin alfa (activated) is a promising new therapy in the treatment of severe sepsis. Nurses caring for patients with this disease need to understand the issues related to the administration of drotrecogin alfa (activated) and the monitoring of patients receiving this drug to promote optimal and appropriate use of this innovative therapy.

Promoting a peaceful death in the ICU

Care for the dying ICU patient and family should be inclusive of respect for their goals, preferences. and choices. Care should be comprehensive, inclusive of all the patient domains (physical, psychosocial and, spiritual), and inclusive of all the specialties and disciplines that can be helpful at this complex time. The families' concerns should be acknowledged and support given. Our ICUs need to develop supportive environments for those dying patients who stay in the unit. Quality improvement and ongoing evaluation will provide avenues of change for care of this special group of patients and families.

Legal and ethical issues in end-of-life care

Advances in medical technology during the past 3 decades altered the scenarios of our dying. It is now possible to prolong life, with the frightening reality that we also can extend death. This paper examines challenges to dying well in America, defines key end-of-life dilemmas faced by critical care nurses, and examines legal and ethical issues related to dying persons' care. These issues include patients' decision-making capacity and right to refuse treatment; withholding and withdrawing life-sustaining treatment, including nutrition and hydration; "no code" decisions; medical futility; and assisted suicide. Implications for critical care practice, education, research and public policy are identified.

End of life care in the ICU: current practice and future hopes

Dying well in the United States is not the standard of care, particularly in critical care units. A number of factors contribute to this clinical deficiency, yet opportunities and strategies to correct the deficiencies are evident through the work of end-of-life advocates and clinical pioneers in nursing and medicine. The purpose of this paper is to describe barriers to optimal end of life care in the ICU and to recommend strategies for making improvements. Ideally, all persons who are not expected to survive a critical illness will experience compassionate, comprehensive, patient and family-focused attention directed at allowing the patient to die well.

Parental role in decision making about pediatric cardiac transplantation: familial and ethical considerations

Parents of children with complex or terminal heart conditions often face agonizing decisions about cardiac transplantation. There are differences in the level of involvement that parents prefer when making such decisions. The purpose of this study was to identify and describe parents' preferences for their roles in decisions related to cardiac transplantation. A prospective ethnographic method was used to study 24 parents of 15 children prior to their decision of accepting or rejecting the transplant option for their children. Findings revealed that the style of parent decision making ranged from a desire to make an independent, autonomous choice to a wish for an authoritarian, paternalistic choice. Nurses and physicians can best support families in this situation, showing sensitivity to the steps that parents use to make their decisions. An ethical model of decision making is proposed that includes respect for differences in beliefs and values of all persons involved in the transplantation discussion.

Preferences for care near the end of life: scale development and validation

The purpose of this study was to develop and validate an instrument, the Preferences for Care near the End of Life (PCEOL) scale. Following a literature review and using the domain-referenced approach and a test grid, a large pool of items was generated to reflect five dimensions of preferences for care near the end of life. These were reviewed for relevance and clarity by an expert panel. A convenience sample of 198 adults was secured to provide data for the study of the psychometric properties of the scale. Data screening and item analysis resulted in a final sample of 43 items. A principal factor analysis (PFA) resulted in an interpretable, meaningful five-factor solution. Reliability estimates (internal consistency) for the factors on the multidimensional instrument ranged from.68 to.91. Retest stability estimates for the PCEOL showed correlations of.80 to.94 for factor scores over a 2-week interval.
