ICU nurses' preparation of families for death of patients following withdrawal of ventilator support

A national Position Statement on adult end-of-life care in critical care

Patient death in critical care is not uncommon. Rather, the provision of end-of-life care is a core feature of critical care nursing, yet not all nurses feel adequately prepared for their role in the provision of end-of-life care. For this reason, the Australian College of Critical Care Nurses (ACCCN) supported the development of a Position Statement to provide nurses with clear practice recommendations to guide the provision of end-of-life care, which reflect the most relevant evidence and information associated with end-of-life care for adult patients in Australian critical care settings. A systematic literature search was conducted between June and July, 2020 in CINAHL Complete, Medline, and EMBASE databases to locate research evidence related to key elements of end-of-life care in critical care. Preference was given to the most recent Australian or Australasian research evidence, where available. Once the practice recommendations were drafted in accordance with the research evidence, a clinical expert review panel was established. The panel comprised clinically active ACCCN members with at least 12 months of clinical experience. The clinical expert review panel participated in an eDelphi process to provide face validity for practice recommendations and a subsequent online meeting to suggest additional refinements and ensure the final practice recommendations were meaningful and practical for critical care nursing practice in Australia. ACCCN Board members also provided independent review of the Position Statement. This Position Statement is intended to provide practical guidance to critical care nurses in the provision of adult end-of-life care in Australian critical care settings.

Seeing the Patient and Family Through: Nurses and Physicians Experiences With Withdrawal of Life-Sustaining Therapy in the ICU

Withdrawal of life-sustaining therapy at the end of life is a complex phenomenon. Intensive care nurses and physicians are faced with caring for patients and supporting families, as these difficult decisions are made. The purpose of this study was to explore and describe the experience of critical care nurses and physicians participating in the process of withdrawal of life-sustaining therapy. A hermeneutic phenomenological approach was used to guide this qualitative investigation. Interviews were conducted with critical care nurses and physicians from 2 medical centers. An inductive approach to data analysis was used to understand similarities between the nurses and the physicians’ experiences. Methodological rigor was established, and data saturation was achieved. The main categories that were inductively derived from the data analysis included from novice to expert, ensuring ethical care, uncertainty to certainty, facilitating the process, and preparing and supporting families. The categories aided in understanding the experiences of nurses and physicians, as they worked individually and together to see patients and families through the entire illness experience, withdrawal of life-sustaining therapy decision-making process and dying process. Understanding the perspectives of health-care providers involved in the withdrawal of life-sustaining therapy process will help other health-care providers who are striving to provide quality care to the dying and to their families.

The effectiveness of interventions to meet family needs of critically ill patients in an adult intensive care unit: a systematic review update

BACKGROUND

Attending to the needs of family members of critically ill patients is an important and necessary step in providing appropriate holistic care for both the patient and the family. Family interaction can significantly impact on the experience of critical illness, notwithstanding the challenge of meeting families' needs for many clinicians in the intensive care unit (ICU). Family needs have been extensively researched; however, a previous Joanna Briggs Institute (JBI) systematic review was the first published systematic review recommending effective interventions for addressing family needs of critically ill patients in an acute intensive care setting. Since its publication in 2011, additional research findings have been published and it was deemed appropriate to update the original systematic review.

OBJECTIVES

This systematic review aims to establish recent best practice in addressing the needs of family members with a relative or loved one admitted to an adult critical care unit.

INCLUSION CRITERIA TYPES OF PARTICIPANTS

Studies that included family members (including children) of adult patients in an ICU were considered for inclusion in this review. Patients with any clinical condition, length of stay or outcome were included.

TYPES OF INTERVENTION(S)

This review considered interventions that addressed the five previously identified categories of family needs: support - support groups, training in coping strategies and journal or diary writing; assurance - face-to-face meetings and participation in ward rounds; proximity - changes to visitation policies; information - staff and/or family education, handouts and brochures and the use of technology (e.g. SMS messages); and comfort - changes to the ICU physical environment.

TYPES OF STUDIES

This review considered any randomized controlled trials (RCTs) that evaluated the effectiveness of interventions in addressing family needs of critically ill patients in an adult ICU. In the absence of RCTs, other research designs such as quasi-experimental, as well as pre- and post-studies were considered for inclusion in the narrative summary to enable the identification of current approaches and possible future strategies for addressing family needs of critically ill patients.

TYPES OF OUTCOMES

This review considered studies that evaluated outcomes with a validated tool that measured information comprehension, coping mechanisms, anxiety, depression, stress and satisfaction.

SEARCH STRATEGY

An extensive search of the major databases was conducted. Databases searched included PubMed, CINAHL, psycINFO, Health source, Web of Science, EMBASE, the Cochrane Library and Database of Abstracts of Reviews of Effects. The original search of this review included published and unpublished studies and articles in English from 1980 to 2010. The updated search identified articles for inclusion from 2010 to 2014.

METHODOLOGICAL QUALITY

Quantitative articles selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review. Any disagreements that arose between the reviewers were resolved through discussion, or with a third reviewer.

DATA EXTRACTION

Data was extracted from the articles included in this review using standardized data extraction tools from the JBI Meta Analysis of Statistics Assessment and Review Instrument package.

DATA SYNTHESIS

The studies included in this review were not suitable for meta-analysis and therefore the results are presented as a narrative summary.

RESULTS

Originally, 14 studies and one dissertation met the inclusion criteria and were included in the review. Of these, 12 were quasi-experimental studies and three were prospective randomized trials. In this current update, 14 new articles were identified for inclusion - one RCT, 10 quasi-experimental studies and three observational studies. The settings were in ICUs in Sweden, USA, United Kingdom, the Netherlands, France, Hong Kong, Saudi Arabia and Iran. The evidence identified from all studies in the review includes the use of support groups for family members of patients admitted to an ICU, structured communication and/or education programs for family members, the use of leaflets or brochures to meet family information needs, use of a diary, changes in the physical environment and open or more flexible visiting hours.

CONCLUSIONS

This current update of the original review makes several reiterative and new recommendations for clinical practice to address family needs of patients admitted to a critical care unit; however, the need for significant further research in this area is again highlighted. Future intervention studies focusing on family needs could include the use of technology such as DVDs (Digital Versatile Discs) and SMS (Short Message Service) for informing families and interventions specifically designed to improve family comfort.

IMPLICATIONS FOR PRACTICE

Communication interventions help promote family involvement in their loved one's care and facilitate their decision-making capacity, as well as improving clinician and family interaction, family comprehension of their loved one's condition and also reduce the development of post-traumatic stress-related symptoms (Grade A). Family satisfaction may be increased with the provision of comfortable physical environments with noise reduction measures (Grade B).

IMPLICATIONS FOR RESEARCH

More rigorous high-quality studies investigating interventions to meet the needs of family with a relative in ICU are needed. The majority of included studies in this updated review focused on family satisfaction wherein more robust data on family needs would better inform health professionals in their practice.

Vigilant attentiveness in families observing deterioration in the dying intensive care patient: A secondary analysis study

BACKGROUND

Family support in intensive care is often focussed on what information is communicated to families. This is particularly important during treatment withdrawal and end of life care. However, this positions families as passive receivers of information. Less is known about what bereaved family members actually observe at end of life and how this is interpreted.

AIM

Secondary analysis study was conducted in order to explore the concept of vigilant attentiveness in family members of adult patients dying in intensive care.

METHOD

Secondary analysis of eight interviews sorted from two primary data sets containing 19 interviews with 25 bereaved family members from two intensive care units in England was undertaken. Directed content analysis techniques were adopted.

FINDINGS

Families are observant for physiological deterioration by watching for changes in cardiac monitors as well as paying attention to how their relative looks and sounds. Changes in treatment/interventions were also perceived to indicate deterioration.

CONCLUSION

Families are vigilant and attentive to deterioration, implying that families are active participants in information gathering. By clarifying what families notice, or do not notice during the dying trajectory in ICU, health care professionals can tailor information, helping to prepare families for the death of their relative.

[The suitability of therapeutic effort: An end-of-life strategy]

End-of-life treatment and attention to the needs of relatives are not adequate for several reasons: Society denies or hides the death; it is very difficult to predict it accurately; treatment is frequently fragmented between different specialists, and there is insufficient palliative medicine training, including communication skills. There are frequent conflicts with decisions made at the end of life, particularly the suitability of therapeutic effort. The attitude of professionals on the adequacy of therapeutic effort is not homogenous, and varies depending on the specialty, experience, and beliefs. Many doctors are still afraid of inconveniencing patients. Primary care is in a privileged position to approach the life and values of our patients and their families, and not just the disease, which makes it the right place to guide and advise the patient on the preparation and registration of living wills.

Causes and consequences of disproportionate care in intensive care medicine

PURPOSE OF REVIEW

Increased use of advanced life-sustaining measures in patients with poor long-term expectations secondary to more chronic organ dysfunctions, comorbidities and/or a poor quality of life has become a worrying trend over the last decade. This can lead to futile, disproportionate or inappropriate care in the ICU. This review summarizes the causes and consequences of disproportionate care in the ICU.

RECENT FINDINGS

Disproportionate care seems to be common in European and North American ICUs. The initiation and prolongation of disproportionate care can be related to hospital facilities, healthcare providers, the patient and his/her representatives and society. This can have serious consequences for patients, their relatives, physicians, nurses and society.

SUMMARY

Disproportionate care is common in western ICUs. It can lead to violation of basic bioethical principles, suffering of patients and relatives and compassion fatigue and moral distress in healthcare providers. Avoiding inappropriate use of ICU resources and disproportionate care in the ICU should have high priority for ICU managers but also for every healthcare provider taking care of patients at the bedside.

Critical Care Nurses’ Perception of Barriers and Supportive Behaviors in End-of-Life Care

Aim:

To investigate critical care nurses' perceptions of barriers and supportive behaviors in providing end of life (EOL) care to dying patients and their families.

Methods:

The study involved a convenient sample of 70 nurses who were involved in caring for critically ill patients. Data were collected using a structured interview sheet.

Results:

Barriers to providing EOL care were related to intensive care environment, family members, nurses' knowledge and skills, physicians' attitudes and treatment policy. Possible help to providing EOL care involved nurses' support to each other, patient and family-centered care, and families' support.

Conclusions:

There is a need to allow the family unlimited access to the dying patient, involve them in patient care and provide them with a private place for grieving.

Comparing clinician ratings of the quality of palliative care in the intensive care unit

OBJECTIVE

There are numerous challenges to successfully integrating palliative care in the intensive care unit. Our primary goal was to describe and compare the quality of palliative care delivered in an intensive care unit as rated by physicians and nurses working in that intensive care unit.

DESIGN

Multisite study using self-report questionnaires.

SETTING

Thirteen hospitals throughout the United States.

PARTICIPANTS

Convenience sample of 188 physicians working in critical care (attending physicians, critical care fellows, resident physicians) and 289 critical care nurses.

MEASUREMENTS AND MAIN RESULTS

Clinicians provided overall ratings of the care delivered by either nurses or physicians in their intensive care unit for each of seven domains of intensive care unit palliative care using a 0-10 scale (0 indicating the worst possible and 10 indicating the best possible care). Analyses included descriptive statistics to characterize measurement characteristics of the ten items, paired Wilcoxon tests comparing item ratings for the domain of symptom management with all other item ratings, and regression analyses assessing differences in ratings within and between clinical disciplines. We used p < .001 to denote statistical significance to address multiple comparisons. The ten items demonstrated good content validity with few missing responses or ceiling or floor effects. Items receiving the lowest ratings assessed spiritual support for families, emotional support for intensive care unit clinicians, and palliative-care education for intensive care unit clinicians. All but two items were rated significantly lower than the item assessing symptom management (p < .001). Nurses rated nursing care significantly higher (p < .001) than physicians rated physician care in five domains. In addition, although nurses and physicians gave comparable ratings to palliative care delivered by nurses, nurses' and physicians' ratings of physician care were significantly different with nurse ratings of this care lower than physician ratings on all but one domain.

CONCLUSION

Our study supports the content validity of the ten overall rating items and supports the need for improvement in several aspects of palliative care, including spiritual support for families, emotional support for clinicians, and clinician education about palliative care in the intensive care unit. Furthermore, our findings provide some preliminary support for surveying intensive care unit clinicians as one way to assess the quality of palliative care in the intensive care unit.

The effectiveness of interventions to meet family needs of critically ill patients in an adult intensive care unit: a systematic review

EXECUTIVE SUMMARY

Background Attending to the needs of family members of critically ill patients is an important and necessary step in providing appropriate care for both the patient and the family. An initial search of the Cochrane and Joanna Briggs Institute Libraries did not reveal any published systematic reviews recommending effective interventions for addressing family needs of critically ill patients in an acute intensive care unit.Objectives This systematic review aims to establish best practice in addressing the needs of family members with a relative admitted to an adult critical care unit.Search strategy An extensive search of the major databases was conducted. Databases searched included: MEDLINE, CINAHL, psycINFO, Health source, Web of science, EMBASE, the Cochrane library and Database of abstracts of reviews of effects (DARE) as well as Pubmed. The search included published and unpublished studies and papers in English from 1980-2010.Selection criteria This review considered any randomised controlled trials that evaluated the effectiveness of interventions in addressing family needs of critically ill patients in an adult intensive care unit. In the absence of randomised controlled trials, other research designs such as quasi-experimental as well as before and after studies were considered for inclusion in the narrative summary to enable the identification of current approaches and possible future strategies for addressing family needs of critically ill patients.Assessment of quality Each included study was assessed by two independent reviewers using the appropriate appraisal checklist developed by the Joanna Briggs Institute.Data collection and analysis Data was extracted from the papers included in this review using standardised data extraction tools from the Joanna Briggs Institute Meta Analysis of Statistics Assessment and Review Instrument package. The studies included in this review were not suitable for meta-analysis and therefore the results are presented in narrative form.Results Fourteen studies and one dissertation met the inclusion criteria and were included in the review. There were 12 quasi-experimental studies identified including 8 two or three group, pre-test/post-test studies; 1 one-way between subjects design; 1 interrupted time series and 1 two-group comparative design study. The dissertation was a quasi-experimental three group pre-test/post-test design. There were 3 prospective randomised trials included. The evidence identified includes: the use of support groups for family members of patients admitted to an intensive care unit, structured communication and/or education programs for family members, the use of leaflets or brochures to meet family information needs and open or more flexible visiting hours.Conclusion/Recommendations This review makes several recommendations for clinical practice to address family needs of patients admitted to a critical care unit, however this review highlights the need for significant further research in this area.

Predictors of time to death after terminal withdrawal of mechanical ventilation in the ICU

BACKGROUND

Little information exists about the expected time to death after terminal withdrawal of mechanical ventilation. We sought to determine the independent predictors of time to death after withdrawal of mechanical ventilation.

METHODS

We conducted a secondary analysis from a cluster randomized trial of an end-of-life care intervention. We studied 1,505 adult patients in 14 hospitals in Washington State who died within or shortly after discharge from an ICU following terminal withdrawal of mechanical ventilation (August 2003 to February 2008). Time to death and its predictors were abstracted from the patients' charts and death certificates. Predictors included demographics, proxies of severity of illness, life-sustaining therapies, and International Classification of Diseases, 9th ed., Clinical Modification codes.

RESULTS

The median (interquartile range [IQR]) age of the cohort was 71 years (58-80 years), and 44% were women. The median (IQR) time to death after withdrawal of ventilation was 0.93 hours (0.25-5.5 hours). Using Cox regression, the independent predictors of a shorter time to death were nonwhite race (hazard ratio [HR], 1.17; 95% CI, 1.01-1.35), number of organ failures (per-organ HR, 1.11; 95% CI, 1.04-1.19), vasopressors (HR, 1.67; 95% CI, 1.49-1.88), IV fluids (HR, 1.16; 95% CI, 1.01-1.32), and surgical vs medical service (HR, 1.29; 95% CI, 1.06-1.56). Predictors of longer time to death were older age (per-decade HR, 0.95; 95% CI, 0.90-0.99) and female sex (HR, 0.86; 95% CI, 0.77-0.97).

CONCLUSIONS

Time to death after withdrawal of mechanical ventilation varies widely, yet the majority of patients die within 24 hours. Subsequent validation of these predictors may help to inform family counseling at the end of life.

Anticipation of distress after discontinuation of mechanical ventilation in the ICU at the end of life

BACKGROUND

A considerable number of patients admitted to the intensive care unit (ICU) die following withdrawal of mechanical ventilation. After discontinuation of ventilation without proper preparation, excessive respiratory secretion is common, resulting in a 'death rattle'. Post-extubation stridor can give rise to the relatives' perception that the patient is choking and suffering. Existing protocols lack adequate anticipatory preparation to respond to all distressing symptoms.

METHODS

We analyzed existing treatment strategies in distressing symptoms after discontinuation of mechanical ventilation.

CONCLUSION

The actual period of discontinuation of mechanical ventilation can be very short, but thoughtful anticipation of distressing symptoms takes time. There is an ethical responsibility to anticipate and treat (iatrogenic) symptoms such as pain, dyspnea-associated respiratory distress, anxiety, delirium, post-extubation stridor, and excessive broncho-pulmonary secretions. This makes withdrawal of mechanical ventilation in ICU patients a thoughtful process, taking palliative actions instead of fast terminal actions. We developed a flowchart covering all possible distressing symptoms that can occur after withdrawal of mechanical ventilation and extubation. We recommend a two-phase process. Six hours before extubation, enteral feeding should be stopped and parenteral fluids reduced, overhydrated patients should be dehydrated with furosemide, administration of sedatives (for distress) and opioids (for pain and/or dyspnea) should be continued or started and methylprednisolone should be given in anticipation of stridor after extubation. Thirty minutes before extubation, Butylscopolamine should be given and methylprednisolone repeated. After this the patient should be extubated to secure a dying process as natural as possible with the lowest burden due to distress.

Preparing Families of Intensive Care Patients for Withdrawal of Life Support: A Pilot Study

Background Most deaths in intensive care occur after withdrawal of life support. Although preparation of patients’ families is recommended, the specific information required has not been theoretically developed or tested.

Objective To assess the feasibility of testing 4 tailored messages to prepare families of patients having a planned withdrawal of life support, to assess barriers to conducting such a study, and to obtain preliminary data on measurable effects that could be used to compare such preparation with usual care. Self-regulation theory was used to structure the messages.

Methods Families were randomly assigned to usual care (n=10) or to an intervention group (n=10) that received 1 of 4 tailored messages to prepare them for withdrawal of life support. They were contacted 2 to 4 weeks later to complete the Profile of Mood States and to give their evaluation of the experience, inclusive of the information received.

Results Compared with the usual-care group, the intervention group was significantly more satisfied with the information they received and understood better what was to happen. The intervention group had lower negative mood scores and higher positive mood scores than did the usual-care group, although the difference was not significant. Unsolicited comments by the usual-care participants were requests for the specific information that had been received by the intervention group.

Conclusions The information provided was considered helpful. A larger sample might yield more significant differences. Further work is needed on other aspects of preparation such as healthcare support, spiritual issues, and preparation for funeral arrangements.

Family support at end of life

Much of the literature for end of life in the intensive care unit focuses on patients and their treatment. Families are usually present and should be a focus, as well as a resource, in end-of-life plans. Using categories from a recently published Society of Critical Care Medicine guideline on family support during an intensive care unit stay and 7 end-of-life domains, literature retrieved since 2000 was summarized. Topics addressed are decision making, spiritual and cultural support, emotional and practical support of families, including visitation and family preparation for death, and continuity of care.

Palliative care consultation in the intensive care unit

Deaths occur frequently in the intensive care unit, yet clinicians in this unique practice environment are often untrained in the care of patients who are dying. Palliative care consultation in the intensive care unit may bridge the gaps between what should be done for dying patients and their families and what is often the default, that is, a prolonged death with inadequate symptom management and not enough family support. Hospital-based palliative care consult services have demonstrated positive patient-assessed and system outcomes, including symptom management, family support, reductions in hospital length of stay, increases in discharge home with hospice referrals, and reduced costs of care. Similar outcomes have been reported about intensive care unit-focused palliative care consultation. Palliative care consultants who seek referrals from the intensive care unit will be successful if strategies such as getting acquainted, learning about the environment and patterns of care, seeking feedback, and respecting the intensive care unit's life-saving efforts are employed. Intensive care staff satisfaction with palliative care consultation will drive future referrals.

Withdrawal of Life-Sustaining Therapy After Sudden, Unexpected Life-Threatening Illness or Injury: Interactions Between Patients’ Families, Healthcare Providers, and the Healthcare System

• Background Withdrawal of life-sustaining therapy in intensive care units is increasing. Patients’ families are intimately involved in this process because the patients are usually unable to participate. Little is known about family members’ interactions with healthcare providers and the healthcare system during this process.

• Objective To describe the interactions between patients’ family members, healthcare providers, and the healthcare system during withdrawal of life-sustaining therapy after a sudden, unexpected illness or injury.

• Methods The investigation was part of a larger interpretative phenomenological study. Nineteen families (56 family members) who participated in the process of withdrawal of life-sustaining therapy for a family member were interviewed and observed. An inductive approach to data analysis was used to discover units of meaning, clusters, and categories.

• Results The families’ experiences involved a variety of dimensions, including issues with healthcare providers (bonds and consistency with nurses and physicians, physicians’ presence, information, coordination of care, family meetings, sensitivity to time, and preparation for the dying process) and issues with the healthcare system (parking, struggles with finding privacy, and transfers of patients).

• Conclusions Patients’ families need information, guidance, and support as the families participate in the process of withdrawal of life-sustaining therapy. The results of this study have important implications for clinical practice and future research.

Interventions to Improve Care during Withdrawal of Life-Sustaining Treatments

Withdrawal of life-sustaining therapies is a common occurrence in the intensive care unit (ICU) setting and also occurs in other hospital settings, long-term care facilities, and even at home. Many studies have documented dramatic geographic variations in the prevalence of withdrawal of life-sustaining therapies, and some evidence suggests this variation may be driven more by physician attitudes and biases than by factors such as patient preferences or cultural differences. A number of studies of interventions in the ICU setting have provided some evidence that withdrawal of life-sustaining therapies is a process of care that can be improved. The interventions have included routine ethics or palliative care consultations, routine family conferences, and standardized order protocol for withdrawal of life support. For some of the interventions, for example, ethics consultations or palliative care consultations, the precise mechanisms by which the process of care is improved are not clear. Furthermore, many of these studies have used surrogate outcomes for quality, such as ICU length of stay. Emerging research suggests more direct outcome measures may be useful, including family satisfaction with care and assessments of the quality of dying. Despite these relative limitations, these studies provide convincing evidence that withdrawal of life-sustaining therapy is a process of care that presents opportunities for quality improvement and that interventions are successful at improving this care. Further research is needed to identify and test the most appropriate and responsive outcome measures and to identify the most effective and cost-effective interventions.

Going home from ICU to die: a celebration of life*

There is much literature regarding going home to die in terminally ill cancer patients however, little is written about withdrawing treatment at home in critical care. One intensive care unit's experience in New Zealand demonstrates how this can be done safely. The preparation of families and patients must be done with great care. There are challenges to be overcome including supportive resources in the community, staffing and safety of the patient and family. It is possible to withdraw/withhold treatment in a patient's home and this is highly valued by the families.
