Information Pamphlet Given to Relatives During the End-of-Life Decision in the ICU: An Assessor-Blinded, Randomized Controlled Trial

Intensive care unit interventions to improve quality of dying and death: scoping review

BACKGROUND

Intensive care units (ICUs) have mortality rates of 10%-29% owing to illness severity. Postintensive care syndrome-family affects bereaved relatives, with a prevalence of 26% at 3 months after bereavement, increasing the risk for anxiety and depression. Complicated grief highlights issues such as family presence at death, inadequate physician communication and urgent improvement needs in end-of-life care. However, no study has comprehensively reviewed strategies and components of interventions to improve end-of-life care in ICUs.

AIM

This scoping review aimed to analyse studies on improvement of the quality of dying and death in ICUs and identify interventions and their evaluation measures and effects on patients.

METHODS

MEDLINE, CINAHL, PsycINFO and Central Journal of Medicine databases were searched for relevant studies published until December 2023, and their characteristics and details were extracted and categorised based on the Joanna Briggs model.

RESULTS

A total of 24 articles were analysed and 10 intervention strategies were identified: communication skills, brochure/leaflet/pamphlet, symptom management, intervention by an expert team, surrogate decision-making, family meeting/conference, family participation in bedside rounds, psychosocial assessment and support for family members, bereavement care and feedback on end-on-life care for healthcare workers. Some studies included alternative assessment by family members and none used patient assessment of the intervention effects.

CONCLUSION

This review identified 10 intervention strategies to improve the quality of dying and death in ICUs. Many studies aimed to enhance the quality by evaluating the outcomes through proxy assessments. Future studies should directly assess the quality of dying process, including symptom evaluation of the patients.

Effectiveness of decision aids on critically ill patients' outcomes and family members' knowledge, anxiety, depression and decisional conflict: A systematic review and meta-analysis

BACKGROUND

Decision aids (DAs) have been proposed to support patients and families with disease information processing and decision-making, but their effectiveness for critically ill patients and their families is incompletely understood.

AIM

To systematically synthesize evidence on the effectiveness of the DAs on the prognosis of critically ill patients and knowledge, anxiety, depression and decisional conflict of their family members.

STUDY DESIGN

Systematic review and meta-analysis. We conducted a systematic search of literature using PubMed, Embase, Cochrane Library, Web of Science, Cumulative Index to Nursing and Allied Health Literature database, Scopus, PsycNet, CNKI and Wanfang Database from the inception of the databases until May 2023 to identify randomized clinical trials (RCTs) describing DAs interventions targeted at adult intensive care unit (ICU) patients or their families. We also searched grey literature in four databases: Chinese Clinical Trials Registry, Chinese Cochrane Center, Open Grey and GreyNet International.

RESULTS

Seven RCTs were included in the review. Meta-analysis identified longer hospital length of stay (LOS) among all patients compared with usual care (mean difference [MD] = 5.64 days, 95% confidence interval, CI [0.29, 10.98], p = .04), but not in surviving patients (MD = 2.09 days, 95% CI [-3.70, 7.89], p = .48). However, there was no evidence of an effect of DAs on hospital mortality (RR = 1.25, 95% CI [0.92, 1.70], p = .15), ICU LOS (MD = 3.77 days, 95% CI [-0.17, 7.70], p = .06) and length of mechanical ventilation (MD = 0.88 days, 95% CI [-2.22, 3.97], p = .58). DAs led to a statistically significant improvement in family members' knowledge (standard mean difference = 0.84, 95% CI [0.12, 1.56], p = .02). We found no significant effect of DAs on anxiety, depression, post-traumatic stress disorder, decisional conflict and quality of communication of family members.

CONCLUSIONS

This review provides effective evidence that DAs can potentially improve the knowledge level of family members while prolonging the hospital LOS among critically ill patients.

RELEVANCE TO CLINICAL PRACTICE

Well-designed large-scale studies with DAs tailored to the individuals' preferences and existing cultural values are warranted.

Interprofessional interventions and factors that improve end-of-life care in intensive care units: An integratory review

INTRODUCTION

The changes in health dynamics, caused by the SARS-COVD-2 pandemic and its consequences, generated a greater need to integrate palliative care in the ICU to promote a dignified death.

OBJECTIVE

Identify interprofessional interventions and factors that improve the care of patients at the end of life.

METHODOLOGY

Integrative review, including experimental, quasi-experimental, observational, analytical, and descriptive studies with correlation of variables, published from 2010 to 2021, identified in COCHRANE, CINAHL, CUIDEN, LILACS, SCIELO, Dialnet, PsychInfo, PubMed, PROQUES, PSYCHOLOGY, JOURNALS, SCIENCEDIRECT, with MeSH/DECS terms: "Critical Care", "IntensiveCare" "Life support care", "Palliative care", "Life Quality", "Right to die". 36,271 were identified, after excluding duplicate title, abstract, year of publication, design, theme, methodological quality, objectives, and content, 31 studies were found.

RESULTS

It included 31 articles, 16.7% experimental, 3.3% quasi-experimental, 80% observational, analytical, and descriptive with correlation of variables, 38% published in the United States, 38%, and 19% in Brazil. The pooled sample was 24,779 participants. 32.2% of the studies had level of evidence 1 recommendation (c), and 25.8% level of evidence 2 recommendation (c). This paper synthesises evidence to promote Interprofessional Collaborative Practice in the ICU, improve end-of-life care, and interventions to achieve established therapeutic goals, implement effective care policies, plans, and programmes for critically ill patients and their families; factors that affect palliative care and improve with training and continuing education for health personnel.

CONCLUSION

There are interventions to manage physical and emotional symptoms, training strategies and emotional support aimed at health personnel and family members to improve the quality of death and reduce stays in the ICU. The interdisciplinary team requires training on palliative and end-of-life care to improve care.

Supporting families of patients who die in adult intensive care: A scoping review of interventions

BACKGROUND

Families who perceive themselves as prepared for an impending death experience reduced psychological burden during bereavement. Understanding which interventions promote death preparedness in families during end-of-life care in intensive care will inform future intervention development and may help limit the burden of psychological symptoms associated with bereavement.

AIM

To identify and characterise interventions that help prepare families for the possibility of death in intensive care, incorporating barriers to intervention implementation, outcome variables and instruments used.

DESIGN

Scoping review using Joanna Briggs methodology, prospectively registered and reported using relevant guidelines.

DATA SOURCES

A systematic search of six databases from 2007 to 2023 for randomised controlled trials evaluating interventions that prepared families of intensive care patients for the possibility of death. Citations were screened against the inclusion criteria and extracted by two reviewers independently.

RESULTS

Seven trials met eligibility criteria. Interventions were classified: decision support, psychoeducation, information provision. Psychoeducation involving physician-led family conference, emotional support and written information reduced symptoms of anxiety, depression, prolonged grief, and post-traumatic stress in families during bereavement. Anxiety, depression, and post-traumatic stress were assessed most frequently. Barriers and facilitators to intervention implementation were seldom reported.

CONCLUSION

This review provides a conceptual framework of interventions to prepare families for death in intensive care, while highlighting a gap in rigorously conducted empirical research in this area. Future research should focus on theoretically informed, family-clinician communication, and explore the benefits of integrating existing multidisciplinary palliative care guidelines to deliver family conference within intensive care.

IMPLICATIONS FOR CLINICAL PRACTICE

Intensive care clinicians should consider innovative communication strategies to build family-clinician connectedness in remote pandemic conditions. To prepare families for an impending death, mnemonic guided physician-led family conference and printed information could be implemented to prepare families for death, dying and bereavement. Mnemonic guided emotional support during dying and family conference after death may also assist families seeking closure.

The Impact of Randomized Family-Centered Interventions on Family-Centered Outcomes in the Adult Intensive Care Unit: A Systematic Review

Objective: To review the literature for randomized family-centered interventions with family-centered outcomes in the adult intensive care unit (ICU). Data Sources: We searched MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane Library database from inception until February 2023. Study Selection: We included articles involving randomized controlled trials (RCTs) in the adult critical care setting evaluating family-centered interventions and reporting family-centered outcomes. Data Extraction: We extracted data on author, year of publication, setting, number of participants, intervention category, intervention, and family-centered outcomes. Data Synthesis: There were 52 RCTs included in the analysis, mostly involving communication and receiving information (38%) and receiving care and meeting family member needs (38%). Nearly two-thirds of studies (N = 35; 67.3%) found improvements in at least 1 family-centered outcome. Most studies (N = 24/40; 60%) exploring the impact of family-centered interventions on mental health outcomes showed improvement. Improvements in patient-centered outcomes (N = 7/17; 41%) and healthcare worker outcomes (N = 1/5; 20%) were less commonly found. Conclusions: Family-centered interventions improve family-centered outcomes in the adult ICU and may be beneficial to patients and healthcare workers.

Deathbed Etiquette - The Guide: A Qualitative Study Exploring the Views of Practitioners on its Introduction into End-of-Life Care Settings

Objectives: It is common for relatives to feel uncertain about what to expect at the bedside of a dying loved one. The Centre for the Art of Dying Well together with clinical, academic and communications experts created a 'Deathbed Etiquette' guide offering information and reassurance to relatives. This study explores the views of practitioners with experience in end-of-life care on the guide and how it might be used. Methods: Three online focus groups and nine individual interviews were conducted with a purposive sample of 21 participants involved in end-of-life care. Participants were recruited through hospices and social media. Data were analysed using thematic analysis. Results: Discussions highlighted the importance of effective communication that normalises experiences of being by the bedside of a dying loved one. Tensions around the use of the words 'death' and 'dying' were identified. Most participants also expressed reservations about the title, with the word 'deathbed' found to be old-fashioned and the word 'etiquette' not capturing the varied experiences of being by the bedside. Overall, however, participants agreed that the guide is useful for 'mythbusting' death and dying. Conclusion: There is a need for communication resources that can support practitioners in having honest and compassionate conversations with relatives in end-of-life care. The 'Deathbed Etiquette' guide is a promising resource to support relatives and healthcare practitioners by providing them with suitable information and helpful phrases. More research is needed on how to implement the guide in healthcare settings.

Do Interventions Improve Symptoms Among ICU Surrogates Facing End-of-Life Decisions? A Prognostically-Enriched Systematic Review and Meta-Analysis

OBJECTIVES

Evaluate the efficacy of interventions to improve symptoms for ICU surrogates at highest risk of developing psychologic distress: those facing end-of-life care decisions.

DATA SOURCES

MEDLINE, CINAHL, PsycInfo, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched through April 16, 2022.

STUDY SELECTION

Following an a priori protocol, randomized trials of interventions delivered to surrogates of adult ICU patients who died or had high likelihood of mortality evaluating surrogate symptoms were identified.

DATA EXTRACTION

Two reviewers performed screening and data extraction and assessed risk of bias (Cochrane Risk of Bias [RoB] 2 tool). Trials were eligible for meta-analysis if group mean symptom scores were provided at 3 or 6 months. Pooled effects were estimated using a random effects model. Heterogeneity was assessed (Cochrane Q, I2 ). Certainty of evidence was assessed (Grading of Recommendations Assessment, Development and Evaluation).

DATA SYNTHESIS

Of 1,660 records, 10 trials met inclusion criteria representing 3,824 surrogates; eight were included in the meta-analysis. Overall RoB was rated Some Concerns. Most ( n = 8) interventions focused on improving communication and enhancing psychologic support in the ICU. All trials measured anxiety, depression, and posttraumatic stress. Significant improvement was seen at 3 months (depression, mean difference [MD], -0.68; 95% CI, -1.14 to -0.22, moderate certainty; posttraumatic stress, standardized MD, -0.25; 95% CI, -0.49 to -0.01, very low certainty) and 6 months (anxiety, MD, -0.70; 95% CI, -1.18 to -0.22, moderate certainty). Sensitivity analyses suggest significant findings may be unstable. Subgroup analyses demonstrated differences in effect by trial location, interventionist, and intervention dose.

CONCLUSIONS

Communication and psychological support interventions in the ICU yielded small but significant improvement in psychological symptoms with moderate to very low certainty evidence in a prognostically-enriched sample of ICU surrogates facing end-of-life care decisions. A new approach to interventions that extend beyond the ICU may be needed.

Patients' Priorities for Surrogate Decision-Making: Possible Influence of Misinformed Beliefs

BACKGROUND

Many patients have three primary goals for how treatment decisions are made for them in the event of decisional incapacity. They want to be treated consistent with their preferences and values, they want their family to be involved in making decisions, and they want to minimize the stress on their family. The present paper investigates how patients' beliefs about surrogate decision-making influence which of these three goals they prioritize. Methods: Quantitative survey of 1,169 U.S. patients to assess their beliefs about surrogate decision-making, and how these beliefs influence patients' priorities for surrogate decision-making. Results: Most patients believed that families in general (68.8%) and their own family in particular (83.4%) frequently, almost always, or always know which treatments the patient would want in the event of incapacity. Patients with these beliefs were more likely to prioritize the goal of involving their family in treatment decision-making over the goal of minimizing family stress. Most patients (77.4%) also believed their family would experience significant stress from helping to make treatment decisions. However, patients' priorities were largely unchanged by this belief. Conclusions: Prior reports suggest that patients overestimate the extent to which their family knows which treatments they want in the event of decisional incapacity. The present analysis adds that these patients might be more likely to prioritize the goal of involving their family in treatment decision-making, even when this results in the family experiencing significant distress. This finding highlights that patients' misinformed beliefs about their family's knowledge might influence patients' priorities for surrogate decision-making, raising important questions for clinical practice, policy, and future research.
