End-of-life practices in European intensive care units: the Ethicus Study

Knowledge, attitudes and practices of multiprofessional clinicians towards assisted dying in ICU: A scoping review

BACKGROUND

Care of the dying is at the forefront in intensive care unit (ICU); however there is persistent debate surrounding clinicians' interventions to aid the dying process and make this more bearable and compassionate for patients. Since the expansion of assisted dying internationally, it is unclear how common this occurs within critical care. This work aims to evaluate the knowledge, attitudes and international practices of ICU clinicians about assisted dying.

METHODS

Systematic literature search of PubMed, Embase and CINAHL including articles discussing the knowledge or attitudes towards and/or practices of assisted dying in ICU. The preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Review guidelines were followed. Records were included from 2002 as the year when assisted dying was first legalised in Belgium and by healthcare professionals. A qualitative data synthesis approach was used.

RESULTS

17 studies were eligible and included in the qualitative analysis. Knowledge of assisted dying was rarely assessed directly in the data, though self-reported knowledge was low apart from in one Canadian survey of ICU physicians. Abilities to define modalities of assisted dying were low across all studies where it was measured. Attitudes were highly variable, ranging from 23.6% to 76.5% in support of assisted dying, though clinicians' answers were inconsistent within and between studies. Actual practices of assisted dying in ICU were rarely measured or discussed, despite evidence of assisted dying in Canada and The Netherlands. Outside of legal pathways, there is also evidence of covert interventions either via non-framework approaches where it is otherwise legal or in countries where there is no supportive legislation.

CONCLUSION

ICU clinicians have heterogeneous knowledge and attitudes towards assisted dying, and overall familiarity remains low. The relevance of assisted dying to the ICU setting remains controversial, and its incidence is unclear.

IMPLICATIONS FOR CLINICAL PRACTICE

Evaluating the attitudes and experiences of ICU clinicians about assisted dying is important to gain insight about clinical practices. This holistic viewpoint is key to develop management strategies focused on humanisation of care for patients and families while understanding how to support multidisciplinary clinicians in critical care so they can provide safe and respectful interventions. The identification of its incidence in legal and illegal frameworks and knowledge gaps is key when developing further research and planning tailored interventions.

Decisions to withdraw or withhold life-sustaining therapies in patients with and without acute brain injury: a secondary analysis of two prospective cohort studies

BACKGROUND

Many deaths in the intensive care unit (ICU) occur after a decision to withdraw or withhold life-sustaining therapies (WLSTs). We aimed to explore the differences in the incidence and timing of WLST between patients with and without acute brain injuries (ABIs).

METHODS

We did a secondary analysis of two prospective, international studies that recruited patients who were invasively or non-invasively ventilated between 2004 and 2016 from 40 countries. ABI was defined as brain trauma, ischaemic stroke, intracranial haemorrhage, seizures, or meningitis-encephalitis. The comparator group included non-ABI conditions. Time to WLST was evaluated by use of cumulative incidence curves. Differences in WLST were analysed by use of multilevel logistic regression.

FINDINGS

Between March 11, 2004, and Dec 17, 2016, we recruited 21 970 patients (16 791 in the WLST analysis), of whom 13 526 (61·6%) were male and 8444 (38·4%) were female and 2896 (13·2%) had ABI. WLST occurred in 2056 (12·2%) of 16 791 patients) and was more common in patients with ABI versus without (372 [17·0%] of 2191 vs 1684 [11·5%] of 14 600; risk difference 5·5%; 95% CI 3·8-7·1; odds ratio [OR] 2·42; 1·89-3·12). WLST decisions occurred earlier in patients with ABI versus patients without ABI (median, 4 days [IQR 2-9] versus 6 days [2-13] after ICU admission; absolute difference, 2 days; 95% CI 1-3). Findings were similar across different ABI subgroups, world regions, and cohort years. Variability among ICUs in WLST decisions for patients with ABI and patients without ABI was high (respectively, median OR, 3·04; 95% CI 2·54-3·67, and median OR 2·59; 2·38-2·78).

INTERPRETATION

Our findings suggest that WLST decisions are significantly more common in patients with ABI versus patients without ABI and occur earlier in this group. The rationale for early WLST following ABI warrants further exploration, accounting for additional neurological factors that were not available in the present analysis.

Consensus statements on end-of-life care in ICU - A Scandinavian multidisciplinary Delphi study

BACKGROUND

End-of-life care in the Intensive Care Unit (ICU) is complex, requiring a balance of ethical, cultural and medical considerations while ensuring comfort and dignity for critically ill patients and their families.

AIM

We aimed to develop a set of core domains for end-of-life care at Scandinavian ICUs along with corresponding consensus statements from patients, families and multidisciplinary experts.

METHODS

In a three-round Delphi study, a multidisciplinary advisory board from Norway, Sweden, Finland, Iceland and Denmark, including ICU physicians, ICU nurses, palliative care specialists and a former ICU patient and family, developed potential end-of-life care domains of interest. Specialists with special competence/interest in end-of-life care and clinicians in all five countries were invited to rank these domains according to their importance and provide recommendations within each domain. The advisory board rephrased the recommendations into statements, which were sent out in the second round for participants to rate based on their level of agreement. Statements that did not achieve consensus in the second round were rephrased and redistributed in the third round.

RESULTS

After the third Delphi round, 59 statements across 10 domains reached consensus. The domains were: 1. Communication at ICU admission, 2. Withholding and withdrawal of therapy and end-of-life care decisions in the ICU, 3. Meeting religious and spiritual needs and the needs of vulnerable patients in the ICU, 4. Extubation and termination of mechanical ventilation at the end of life in the ICU, 5. Management and monitoring of symptoms at the end of life in the ICU, 6. Continuous sedation at the end of life in the ICU, 7. Indicators for specialist palliative care consultations in the ICU, 8. Patient transfers from the ICU at the end of life, 9. Bereavement care and 10. Debriefing in the ICU following a patient's death.

DISCUSSION

We developed core domains and consensus statements aiming at optimising end-of-life care that considers cultural and ethical nuances. The domains may help to shape end-of-life care guidelines in Scandinavian ICUs.

Connect or detach: A transformative experience for medical students in end-of-life care

CONTEXT

At the beginning of clinical practice, medical students face complex end-of-life (EoL) decisions, such as limiting life-sustaining therapies, which may precipitate emotionally charged moral dilemmas. Previous research shows these dilemmas may cause identity dissonance and impact students' personal and professional development. Despite the prevalence of such dilemmas, medical educators have limited insight into how students navigate these often emotional experiences. This study explores how medical students make sense of and deal with moral dilemmas lived during EoL's care.

METHODS

This cross-sectional qualitative study used thematic analysis (Braun and Clarke) to analyse interviews with 11 Brazilian final-year medical students. The interviews followed the drawing of a rich picture representing moral dilemmas experienced by medical students when engaging with EoL care. The reporting of this study follows the Standards for Reporting Qualitative Research (SRQR).

RESULTS

Participants highlighted four main themes when engaging with EoL care: 'experiencing death', 'making decisions at the end-of-life', 'connecting versus detaching: an upsetting dilemma' and 'being transformed'. They described the emotional overwhelm of experiencing death and the uncertainty in navigating EoL decisions. The central moral dilemma faced was whether to connect with or detach from patients. This dilemma was lived in the context of a hidden curriculum that preaches emotional distancing as a coping mechanism. Developing the moral courage to overcome this barrier and choosing to connect became a transformative experience, significantly impacting their personal and professional development and reinforcing their commitment to patient-centred care.

CONCLUSION

Connecting with patients in EoL care involves breaking cultural norms to establish meaningful connections with patients aiming for compassionate care. This process may lead to identity dissonance and also represents an opportunity for transformative learning. Educators can support this transformative process by legitimating students' connections with patients, teaching emotional regulation strategies, and leveraging personal experiences to foster trust.

Opinion of Polish doctors on the use of futile therapy

The discontinuation of futile therapy is increasingly discussed in Polish clinical practice. Given the need to ensure patient well-being, it is essential to consider whether all clinical options resulting from medical progress should be used for every patient and on what grounds decisions to limit therapy should be based. The aim of our study was to determine the opinions of Polish medical doctors on this topic. We anonymously surveyed physicians across various specialties. An analysis of the collected data was carried out using descriptive and analytical methods. A total of 323 physicians participated in the study; 93% of them were aware of the problem of futile therapy in adults, with intensivists being significantly more aware (P = 0.002). Additionally, 95% of respondents supported the idea of discontinuing futile therapy, and over 68% used the therapy discontinuation protocol. Among the most common reasons for undertaking futile therapy, respondents cited fear of legal liability (93.5%), as well as fear of being accused of unethical behavior (62.2%) and fear before talking to the patient/patient's family and their reactions (57.9%). Respondents also identified factors that would facilitate making decisions about limiting futile therapy, including precise qualification criteria for limiting therapy and education in this area (95.3%), the patient's declaration of will (87.5%), and a clear legal act (81.3%). The majority of study participants supported the idea of limiting futile therapy, and this issue is well known among Polish physicians.

Randomized Clinical Trial of the Four Supports Intervention for Surrogate Decision-Makers in Intensive Care Units

Rationale: Individuals acting as surrogate decision-makers for critically ill patients frequently struggle in this role and experience high levels of long-term psychological distress. Prior interventions that were designed solely to improve information sharing between clinicians and family members have been ineffective. Objectives: We sought to examine the impact of a multicomponent family support intervention on patient and family outcomes. Methods: We conducted a patient-level randomized clinical trial at six ICUs in a healthcare system in Pennsylvania. An external interventionist interacted daily with surrogate decision-makers for incapacitated, critically ill patients at high risk of death or severe long-term functional impairment to deliver four types of protocolized support during the ICU stay: emotional support; communication support; decisional support; and, if indicated, anticipatory grief support. The control condition involved usual care plus two brief education sessions about critical illness. Measurements and Main Results: Primary outcome was the surrogates' scores on the Hospital Anxiety and Depression Scale at 6 months (range = 0-42). A total of 444 surrogates of 291 patients were enrolled (233 surrogates in intervention and 211 in control). The Four Supports intervention was delivered with high fidelity (frequency of per protocol delivery of key intervention elements, 97.1%; quality rating of intervention delivery, 2.9 ± 0.2 on a scale ranging from 1 to 3, with higher scores indicating higher quality of intervention delivery). There was no intervention effect on the primary outcome, surrogates' Hospital Anxiety and Depression Scale total scores at 6-month follow-up (β = 0.06; 95% confidence interval, -0.07 to 0.19; P = 0.35), or the prespecified secondary outcomes. Conclusions: Among critically ill patients at high risk of death or functional impairment, a family support intervention delivered by an external interventionist did not reduce surrogates' long-term psychological symptom burden.Clinical trial registered with www.clinicaltrials.gov (NCT01982877).

All pet owners are not the same: End-of-Life caregiver expectations and profiles

The study aims to explore the specific needs of French pet owners who have experienced the loss of a pet, recognizing the limited focus on end-of-life and palliative care in veterinary practice. By characterizing owner profiles, the research seeks to enhance veterinary approaches and education to better address the unique challenges and emotional aspects associated with pet care and loss. An anonymous online survey was distributed to 302 French owners who already experienced the loss of an animal, including demographic information and feelings about their experience of a pet's end-of-life (EOL). Data were analysed using descriptive and qualitative analysis (including the use of AI chatbot ChatGPT). 56.6 % of participants reported a relatively smooth pet death, yet 67.0 % found the end-of-life period challenging. Three distinct owner groups emerged, each with varying needs. The first group expressed high guilt and a greater need for support, emphasizing the necessity for information and improved training. The second group, more informed and independent, benefits from veterinary support, while a leaflet suits them. The third group, competent in pain evaluation, requires less veterinary support. These differences highlight the importance of personalized owner support. The study proposes essential pillars for veterinarians and nurses' training, forming the EPITO system: Emotional support, Personalization, Information, Training, Tools, and Open discussion.

Regional differences in triage decisions affect hospital mortality among frail COVID-19 patients in the COvid MEdicaTion study

OBJECTIVES

The scarcity of intensive care unit (ICU) beds during the COVID-19 pandemic has led to a large number of national and international guidelines for the triage of ICU admission. Regional variation in medical decision making might affect ICU triage decisions. We investigate whether regional differences in ICU admission, as surrogate for triage decisions, affect in-hospital mortality in COVID-19 patients.

METHODS

The COMET study is a multicenter, observational cohort study, including adult patients hospitalized for COVID-19 between March 2020- July 2020. Patients' characteristics, prescribed medication, clinical characteristics, and CFS were collected. Patients from 11 European countries were included and these countries were categorized into two regions: north and south. The effects of region on ICU admission and in-hospital mortality were assessed using logistic regression analyses stratified for frailty.

RESULTS

Frail patients had a higher risk for ICU admission in southern compared to northern countries (OR: 1.64; 95%CI: 1.10-2.46), whereas fit patients had a similar risk for ICU admission in southern compared to northern countries (OR: 0.75; 95%CI: 0.55-1.01). There was no difference in in-hospital mortality between northern and southern countries for fit and frail patients (respectively OR: 0.82; 95% CI 0.52-1.29, and OR: 1.11; 95% CI: 0.74-1.66).

CONCLUSION

Our study shows that, despite variation in rates of ICU admission between northern and southern countries for frail patients, no difference in in-hospital mortality was observed. This might help optimize prioritization of resources in a pandemic setting while offering options for palliative care instead of ICU admission.

End-of-life care for the devout Jewish patient

RATIONALE

The Joint Commission emphasizes the importance of cultural competence and effective communication in quality medical care, particularly during end-of-life (EOL), when decisions are influenced by diverse cultural and religious backgrounds. For Orthodox Jewish patients, the philosophical framework used for EOL decision-making may conflict with that used in traditional Western medical ethics. In this paper, we explore the complexities of EOL decision-making for devout Jewish patients and highlight how approaches may differ from a Western ethical framework.

AIMS AND OBJECTIVES

This paper aims to familiarize clinicians with EOL preferences of Orthodox Jewish patients, organized into an ethical framework called 'casuistic deontology'. Leading with an open-minded approach emphasizing cultural humility, we explore ways in which integrating this perspective can allow for culturally appropriate and compassionate EOL care.

METHOD

Using a case study methodology, we focus on a 79-year-old Orthodox Jewish male hospitalized with severe injuries. The patient's medical course is analyzed, highlighting how the decisions made by his family in consultation with their Rabbi may differ from the decisions made with a philosophy of a Western ethical framework.

RESULTS AND CONCLUSION

This case illustrates the ethical tensions that may arise when Western medical practices intersect with Orthodox Jewish beliefs, particularly regarding brain death, resuscitation, and artificial nutrition. We underscore the need for cultural sensitivity when approaching EOL decision-making, allowing for compassionate and comprehensive care that respects religious perspectives. This paper helps provide a structure for clinicians to navigate the complex EOL care needs for the devout Jewish patient in a manner consistent with their cultural and religious identity.

Understanding Staff Needs for Improving End-Of-Life Care in Critical Care Units: A Qualitative Focus Group Analysis and Service Evaluation

Objectives: Critical care is a place of frequent death, up to a quarter of those admitted die during admission. Caring for dying people provides many challenges, practically, professionally and personally. The aim of this study was to better understand the perspectives of staff caring for dying people in critical care and identify their priorities for improvement. Method: Three multidisciplinary focus groups of critical care staff at a large central London hospitals trust were facilitated with a semi structured format and digitally transcribed. Inductive thematic analysis was conducted to extract themes. Results: N = 34 (18 nursing, 7 allied health professionals, 6 medical, 3 clerical/administrative). The five themes were structured as priority statements: "We need to recognise" included the subthemes of being "sick enough to die" and potential rapid deteriorations in this setting; "We need to understand" with subthemes of perspectives on dying and prioritising time for conversations; "We need to connect" with subthemes of therapeutic relationship and physical presence; "We need to collaborate" with subthemes of critical care working and empowerment, and cross teams working; "We need support" with themes of experiencing support and making time to support others. Conclusion: We present an approach to identifying critical care departmental priorities for an end-of-life care improvement programme. The themes extracted will be used to evaluate systems for dying in critical care, aiming to empower staff to provide excellent care every time they look after a dying person. Relevance to Practice: This service evaluation identifies key priorities among critical care staff regarding end-of-life care. The insights can guide service improvements, such as tailored training and enhanced support for staff, to ensure better communication, collaboration, and quality care for patients at the end of life.

Intractable conflicts over end-of-life decisions: A descriptive and ethical analysis of French case-law

CONTEXT

In European and Anglo-Saxon countries, life-sustaining treatment (LST) limitation decisions precede more than 80% of ICU deaths. However, there is now increasing evidence of disagreement and conflict between clinical teams and family members over LST limitation decisions. In some cases, these conflicts are brought to the courts. The aim of this study was to provide a descriptive and qualitative analysis of cases brought to the French courts.

METHODS

We conducted a retrospective national observational study. All identified cases of emergency recourse to the judge in the context of LST limitation decisions in France between 2005 and 2022 were included.

RESULTS

Seventy-six cases were investigated by the judge, with an increasing number over the years. The LST limitation decisions contested by the relatives were mainly decisions to withdraw treatment (78%) concerning patients with neurological injury (76%). The judge successively assessed the compliance with the legal decision-making process and the characterization of the inappropriateness of treatments. The latter was assessed by the judge using medical and non-medical criteria. In all, the medical decision was upheld in 29 cases (38%) and over-ruled in 20 cases (26%). Thirteen cases (17%) were finally settled out of court, and 14 patients (18%) died before the end of the investigation. The qualitative analysis highlighted opposing moral values and principles put forward by family members and physicians.

CONCLUSION

The growing incidence and deeply intertwined elements of these conflicts call for more policy and research to resolve them before they go to court.

ICU Admission Preferences in the Hypothetical Event of Acute Critical Illness: A Survey of Very Old Norwegians and Their Next-of-Kins

OBJECTIVES

To explore older patients' ICU admission preferences and their next-of-kins' ability to predict these preferences.

DESIGN

Self-administered survey.

SETTING

Three outpatient clinics, urban tertiary teaching hospital, Norway.

PATIENTS

Purposive sample of outpatients 80 years old or older regarded as potential ICU candidates and their next-of-kins.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We asked about the patients' ICU admission preferences in three hypothetical scenarios of acute critical illness. Next-of-kin respondents were asked to make a proxy statement regarding the older respondents' wishes regarding ICU admission. For each treatment choice, all respondents could provide their level of confidence. Additionally, we sought to identify demographic and healthcare-related characteristics that potentially influenced ICU admission preferences and proxy accuracy. Of 202 outpatients 80 years old or older, equal proportions opted for (39%; CI, 33-45%) and against (40%; CI, 34-46%) ICU admission, and one in five (21%; CI, 17-26%) did not wish to engage decision-making. Male gender, religiosity, and prior ICU experience increased the likelihood of older respondents opting for ICU admission. Although next-of-kins' proxy statements only weakly agreed with the older respondents' true ICU admission preferences (52%; CI, 45-59%), they agreed with the next-of-kins' own ICU admission preferences (79%; CI, 73-84%) to a significantly higher degree. Decisional confidence was high for both the older and the next-of-kin respondents.

CONCLUSIONS

In this purposive sample of Norwegian potential ICU candidates 80 years old or older, we found substantial variation in the ICU admission preferences of very old patients. The next-of-kins' proxy statements did not align with the ICU admission preferences of the older respondents in half of the pairs, but next-of-kins' and older respondents' confidence levels in rendering these judgments were high.

A window of opportunity for ICU end-of-life care-A retrospective multicenter cohort study

BACKGROUND

The "window of opportunity" for intensive care staff to deliver end-of-life (EOL) care lies in the timeframe from "documenting the diagnosis of dying" to death. Diagnosing the dying can be a challenging task in the ICU. We aimed to describe the trajectories for dying patients in Danish intensive care units (ICUs) and to examine whether physicians document that patients are dying in time to perform EOL care and, if so, when a window of opportunity for EOL care exists.

METHODS

From the Danish Intensive Care Database, we identified patients ≥18 years old admitted to Danish ICUs between January and December 2020 with an ICU stay of >96 h (four days) and who died during the ICU stay or within 7 days after ICU discharge. A chart review was performed on 250 consecutive patients admitted from January 1, 2020, to ICUs in the Central Denmark Region.

RESULTS

In most charts (223 [89%]), it was documented that the patient was dying. Of those patients who received mechanical ventilation, 171 (68%) died after abrupt discontinuation of mechanical ventilation, and 63 (25%) died after gradual withdrawal. Patients whose mechanical ventilation was discontinued abruptly died after a median of 1 h (interquartile range [IQR]: 0-15) and 5 h (IQR: 2-15) after a diagnosis of dying was recorded. In contrast, patients with a gradual withdrawal died after a median of 108 h (IQR: 71-189) and 22 h (IQR: 5-67) after a diagnosis of dying was recorded.

CONCLUSIONS

EOL care hinges on the ability to diagnose the dying. This study shows that there is a window of opportunity for EOL care, particularly for patients who are weaned from mechanical ventilation. This highlights the importance of intensifying efforts to address EOL care requirements for ICU patients and those discharged from ICUs who are not eligible for readmission.

European Society of Intensive Care Medicine guidelines on end of life and palliative care in the intensive care unit

The European Society of Intensive Care Medicine (ESICM) has developed evidence-based recommendations and expert opinions about end-of-life (EoL) and palliative care for critically ill adults to optimize patient-centered care, improving outcomes of relatives, and supporting intensive care unit (ICU) staff in delivering compassionate and effective EoL and palliative care. An international multi-disciplinary panel of clinical experts, a methodologist, and representatives of patients and families examined key domains, including variability across countries, decision-making, palliative-care integration, communication, family-centered care, and conflict management. Eight evidence-based recommendations (6 of low level of evidence and 2 of high level of evidence) and 19 expert opinions were presented. EoL legislation and the importance of respecting the autonomy and preferences of patients were given close attention. Differences in EoL care depending on country income and healthcare provision were considered. Structured EoL decision-making strategies are recommended to improve outcomes of patients and relatives, as well as staff satisfaction and mental health. Early integration of palliative care and the use of standardized tools for symptom assessment are suggested for patients at high risk of dying. Communication training for ICU staff and printed communication aids for families are advocated to improve outcomes and satisfaction. Methods for enhancing family-centeredness of care include structured family conferences and culturally sensitive interventions. Conflict-management protocols and strategies to prevent burnout among healthcare professionals are also considered. The work done to develop these guidelines highlights many areas requiring further research.

The Influence of Geography, Religion, Religiosity and Institutional Factors on Worldwide End-of-Life Care for the Critically Ill: The WELPICUS Study

OBJECTIVE

To evaluate the association between provider religion and religiosity and consensus about end-of-life care and explore if geographical and institutional factors contribute to variability in practice.

METHODS

Using a modified Delphi method 22 end-of-life issues consisting of 35 definitions and 46 statements were evaluated in 32 countries in North America, South America, Eastern Europe, Western Europe, Asia, Australia and South Africa. A multidisciplinary, expert group from specialties treating patients at the end-of-life within each participating institution assessed the association between 7 key statements and geography, religion, religiosity and institutional factors likely influencing the development of consensus.

RESULTS

Of 3049 participants, 1366 (45%) responded. Mean age of respondents was 45 ± 9 years and 55% were females. Following 2 Delphi rounds, consensus was obtained for 77 (95%) of 81 definitions and statements. There was a significant difference in responses across geographical regions. South African and North American respondents were more likely to encourage patients to write advance directives. Fewer Eastern European and Asian respondents agreed with withdrawing life-sustaining treatments without consent of patients or surrogates. While respondent's religion, years in practice or institution did not affect their agreement, religiosity, physician specialty and responsibility for end-of-life decisions did.

CONCLUSIONS

Variability in agreement with key consensus statements about end-of-life care is related primarily to differences among providers, with provider-level variations related to differences in religiosity and specialty. Geography also plays a role in influencing some end-of-life practices. This information may help understanding ethical dilemmas and developing culturally sensitive end-of-life care strategies.

Variability in forgoing life-sustaining treatment practices in critically Ill patients with hospital-acquired bloodstream infections: a secondary analysis of the EUROBACT-2 international cohort

BACKGROUND

The decision to forgo life-sustaining treatment in intensive care units (ICUs) is influenced by ethical, cultural, and medical factors. This study focuses on a population of patients with hospital-acquired bloodstream infections (HABSI) to investigate the association between patient, pathogen, center and country-level factors and these decisions.

METHODS

We analyzed data from the EUROBACT-2 study (June 2019-January 2021) from 265 centers worldwide, focusing on non-COVID-19 patients who died in the hospital or within 28 days after HABSI. We assessed whether death was preceded by a decision to forgo life-sustaining treatment, examining country, center, patient, and pathogen variables. To assess the association of each potentially important variable with the decision to forgo life-sustaining treatment, univariable mixed logistic regression models with a random center effect were performed.

RESULTS

Among 1589 non-COVID-19 patients, 519 (32.7%) died, with 191 (36.8%) following a decision to forgo life-sustaining treatment. Significant geographical differences were observed, with no reported decisions to forgo life-sustaining treatment in African countries and fewer in the Middle East compared to Western Europe, Australia, and Asia. Once a center effect was considered, only health expenditure (Odds ratio 1.79, 95%CI: 1.45-2.21, p < 0.01) and age (Odds ratio 1.02, 95%CI: 1.002-1.05, p = 0.03) were significantly associated with decisions to forgo life-sustaining treatment, while other patient and pathogen factors were not.

CONCLUSION

Economic and regional disparities significantly impact end-of-life decision-making in ICUs. Global policies should consider these disparities to ensure equitable end-of-life care practices.

End-of-Life Practices in an Intensive Care Unit of a Private Hospital in Mexico

Background

Many factors, such as religion, geography, and customs, influence end-of-life practices. This variability exists even between different physicians.

Objective

To observe and describe the end-of-life actions of patients in the intensive care unit (ICU) and document the variables that might influence decision-making at the end of life.

Materials and Methods

This is a cross-sectional study performed in the ICU patients of a private hospital from March 2017 to March 2022. We used the Philips Tasy Electronic Medical Record database of clinical records; 298 patients were included in the study during these five years (2017-2022). The data analysis was done with the statistical package SPSS version 23 for Windows.

Results

A total of 297 patients were included in this study, of which more than half were men. About 60% of our sample had private health insurance, whereas the remaining paid out of pocket. Most patients had withholding treatment, followed by failed cardiopulmonary resuscitation, withdrawal treatment, and brain death, and none of the patients had acceleration of the dying process. The main cause of admission to the ICU in our center was respiratory complications. Most of our samples were Catholics.

Conclusions

Decision-making at the end of life is a complex process. Active participation of the patient, when possible, the patient's family, doctors, and nurses, can give different perspectives and a more compassionate and individualized approach to end-of-life care.

Navigating the shadows: medical professionals' values and perspectives on end-of-life care within pediatric intensive care units in Croatia

Background and aim

This study explores healthcare professionals' perspectives on end-of-life care in pediatric intensive care units (ICUs) in Croatia, aiming to illuminate their experiences with such practices, underlying attitudes, and major decision-making considerations. Amid the high variability, complexity, and emotional intensity of pediatric end-of-life decisions and practices, understanding these perspectives is crucial for improving care and policies.

Methods

The study utilized a cross-sectional survey intended for physicians and nurses across all pediatric ICUs in Croatia. It included healthcare professionals from six neonatal and four pediatric ICUs in total. As the data from neonatal and pediatric ICUs were examined jointly, the term pediatric ICU was used to denominate both types of ICUs. A statistical analysis was performed using Python and JASP, focusing on professional roles, professional experience, and regional differences.

Results

The study included a total of 103 participants (with an overall response rate-in relation to the whole target population-of 48% for physicians and 29% for nurses). The survey revealed diverse attitudes toward and experiences with various aspects of end-of-life care, with a significant portion of healthcare professionals indicating infrequent involvement in life-sustaining treatment (LST) limitation discussions and decisions, as well as somewhat ambiguous attitudes regarding such practices. Notably, discrepancies emerged between different professional roles and, in particular, regions, underscoring the high variability of LST limitation-related procedures.

Conclusions

The findings highlight a pressing need for more straightforward guidelines, legal frameworks, support mechanisms, and communication strategies to navigate the complex terrain of rather burdensome end-of-life pediatric care, which is intrinsically loaded with profound ethical quandaries.

Limitations of life-sustaining therapies in South Africa

PURPOSE

Limitations of life sustaining therapies (LLST) are frequent in intensive care units (ICUs), but no previous studies have examined end-of-life (EOL) care and LLST in South Africa (SA).

MATERIALS AND METHODS

This study evaluated LLST in SA from the data of a prospective, international, multicentre, observational study (Ethicus-2) and compared practices with countries in the rest of the world.

RESULTS

LLST was relatively common in SA, and withholding was more frequent than withdrawing therapy. However, withdrawing and withholding therapy were less common, while failed CPR was more common, than in many other countries. No patients had an advance directive. Primary reasons for LLST in SA were poor quality of life, multisystem organ failure and patients' unresponsiveness to maximal therapy. Primary considerations for EOL decision-making were good medical practice and patients' best-interest, with the need for an ICU bed only rarely considered.

CONCLUSIONS

Withholding was more common than withdrawing treatment both in SA and worldwide, although both were significantly less frequent in SA compared with the world average.

Limitation of life sustaining therapy in disorders of consciousness: ethics and practice

Clinical conversations surrounding the continuation or limitation of life-sustaining therapies (LLST) are both challenging and tragically necessary for patients with disorders of consciousness (DoC) following severe brain injury. Divergent cultural, philosophical and religious perspectives contribute to vast heterogeneity in clinical approaches to LLST-as reflected in regional differences and inter-clinician variability. Here we provide an ethical analysis of factors that inform LLST decisions among patients with DoC. We begin by introducing the clinical and ethical challenge and clarifying the distinction between withdrawing and withholding life-sustaining therapy. We then describe relevant factors that influence LLST decision-making including diagnostic and prognostic uncertainty, perception of pain, defining a 'good' outcome, and the role of clinicians. In concluding sections, we explore global variation in LLST practices as they pertain to patients with DoC and examine the impact of cultural and religious perspectives on approaches to LLST. Understanding and respecting the cultural and religious perspectives of patients and surrogates is essential to protecting patient autonomy and advancing goal-concordant care during critical moments of medical decision-making involving patients with DoC.

Impact of a family support intervention on hospitalization costs and hospital readmissions among ICU patients at high risk of death or severe functional impairment

BACKGROUND

Patients with advanced critical illness often receive more intensive treatment than they would choose for themselves, which contributes to high health care costs near the end of life. The purpose of this study was to determine whether a family support intervention delivered by the interprofessional ICU team decreases hospitalization costs and hospital readmissions among critically ill patients at high risk of death or severe functional impairment.

RESULTS

We examined index hospitalization costs as well as post-discharge utilization of acute care hospitals, rehabilitation and skilled nursing facilities, and hospice services for the PARTNER trial, a multicenter, stepped-wedge, cluster randomized trial of an interprofessional ICU family support intervention. We determined patients' total controllable and direct variable costs using a computerized accounting system. We determined post-discharge resource utilization (as defined above) by structured telephone interview at 6-month follow-up. We used multiple variable regression modelling to compare outcomes between groups. Compared to usual care, the PARTNER intervention resulted in significantly lower total controllable costs (geometric mean: $26,529 vs $32,105; log-linear coefficient: - 0.30; 95% CI - 0.49, - 0.11) and direct variable costs ($3912 vs $6034; - 0.33; 95% CI - 0.56, - 0.10). A larger cost reduction occurred for decedents ($20,304 vs. $26,610; - 0.66; 95% CI - 1.01, - 0.31) compared to survivors ($31,353 vs. $35,015; - 0.15; 95% CI - 0.35,0.05). A lower proportion in the intervention arm were re-admitted to an acute care hospital (34.9% vs 45.1%; 0.66; 95% CI 0.56, 0.77) or skilled nursing facility (25.3% vs 31.6%; 0.63; 95% CI 0.47, 0.84).

CONCLUSIONS

A family support intervention delivered by the interprofessional ICU team significantly decreased index hospitalization costs and readmission rates over 6-month follow-up. Trial registration Trial registration number: NCT01844492.

Variations in reporting of nurse involvement in end-of-life practices in intensive care units worldwide (ETHICUS-2): A prospective observational study

BACKGROUND

ICU nurses are most frequently at the patient's bedside, providing care for both patients and family members. They perform an essential role and are involved in decision-making. Despite this, research suggests that nurses have a limited role in the end-of-life decision-making process and are occasionally not involved.

OBJECTIVE

Explore global ICU nurse involvement in end of life decisions based on the physician's perceptions and sub-analyses from the ETHICUS-2 study.

DESIGN

This is a secondary analysis of a prospective multinational, observational study of the ETHICUS-2 study.

SETTING

End of life decision-making processes in ICU patients were studied during a 6-month period between Sept 1, 2015, and Sept 30, 2016, in 199 ICUs in 36 countries.

INTERVENTION

None.

METHODS

The ETHICUS II study instrument contained 20 questions. This sub-analysis addressed the four questions related to nurse involvement in end-of-life decision-making: Who initiated the end-of-life discussion? Was withholding or withdrawing treatment discussed with nurses? Was a nurse involved in making the end-of-life decision? Was there agreement between physicians and nurses? These 4 questions are the basis for our analysis. Global regions were compared.

RESULTS

Physicians completed 91.8 % of the data entry. A statistically significant difference was found between regions (p < 0.001) with Northern Europe and Australia/New Zealand having the most discussion with nurses and Latin America, Africa, Asia and North America the least. The percentages of end-of-life decisions in which nurses were involved ranged between 3 and 44 %. These differences were statistically significant. Agreement between physicians and nurses related to decisions resulted in a wide range of responses (27-86 %) (p < 0.001). There was a wide range of those who replied "not applicable" to the question of agreement between physicians and nurses on EOL decisions (0-41 %).

CONCLUSION

There is large variability in nurse involvement in end-of-life decision-making in the ICU. The most concerning findings were that in some regions, according to physicians, nurses were not involved in EOL decisions and did not initiate the decision-making process. There is a need to develop the collaboration between nurses and physicians. Nurses have valuable contributions for best possible patient-centered decisions and should be respected as important parts of the interdisciplinary team.

TWEETABLE ABSTRACT

Wide global differences were found in nurse end of life decision involvement, with low involvement in North and South America and Africa and higher involvement in Europe and Australia/New Zealand.

Practice and Predictors of Do-Not-Resuscitate Orders in a Tertiary-Care Intensive Care Unit in Saudi Arabia

Introduction

The objective of this study was to describe Do-Not-Resuscitate (DNR) practices in a tertiary-care intensive care unit (ICU) in Saudi Arabia, and determine the predictors and outcomes of patients who had DNR orders.

Methods

This retrospective cohort study was based on a prospectively collected database for a medical-surgicalIntensive CareDepartment in a tertiary-care center in Riyadh, Saudi Arabia (1999-2017). We compared patients who had DNR orders during the ICU stay with those with "full code." The primary outcome was hospital mortality. The secondary outcomes included ICU mortality, tracheostomy, duration of mechanical ventilation, and length of stay in the ICU and hospital.

Results

Among 24790 patients admitted to the ICU over the 19-year study period, 3217 (13%) had DNR orders during the ICU stay. Compared to patients with "full code," patients with DNR orders were older (median 67 years [Q1, Q3: 55, 76] versus 57 years [Q1, Q3: 33, 71], p < 0.0001), were more likely to be females (43% versus 38%, p < 0.0001), had worse premorbid functional status (WHO performance status scores 4-5: 606[18.9%] versus 1894[8.8%], p < 0.0001), higher prevalence of comorbid conditions, and higher APACHE II score (median 28 [Q1, Q3: 23, 34] versus 19 [Q1, Q3: 13, 25], p < 0.0001) and were more likely to be mechanically ventilated (83% versus 55%, p < 0.0001). Patients had DNR orders were more likely to die in the ICU (67.8% versus 8.5%, p < 0.0001) and hospital (82.4% versus 18.1%, p < 0.0001). On multivariable logistic regression analysis, the following were associated with an increased likelihood of DNR status: increasing age (odds ratio (OR) 1.01, 95% confidence interval (CI) 1.01-1.02), higher APACHE II score (OR 1.09, 95% CI 1.08-1.10), and worse WHO performance status score. Patients admitted in recent years (2012-2017 versus 2002-2005) were less likely to have DNR orders (OR 0.35, 95% CI 0.32-0.39, p < 0.0001). Patients with DNR orders had higher ICU mortality, more tracheostomies, longer duration of mechanical ventilation and length of ICU stay compared to patients with with "full code" but they had shorter length of hospital stay.

Conclusion

In a tertiary-care hospital in Saudi Arabia, 13% of critically ill patients had DNR orders during ICU stay. This study identified several predictors of DNR orders, including the severity of illness and poor premorbid functional status.

Limitation of life support treatments in Spanish Intensive Care Units: Analysis of the ETHICUS II study

OBJECTIVE

The aim of this study is to describe the results of Spanish ICUs in ETHICUS II study.

DESIGN

Planned substudy of patients from ETHICUS II study.

SETTING

12 Spanish ICU.

PATIENTS OR PARTICIPANTS

Patients admitted to Spanish ICU who died or in whom a limitation of life-sustaining treatment (LLST) was decided during a recruitment period of 6 months.

INTERVENTIONS

Follow-up of patients was performed until discharge from the ICU and 2 months after the decision of LLST or death.

MAIN VARIABLES OF INTEREST

Demographic characteristics, clinical profile, type of decision of LLST, time and form in which it was adopted. Patients were classified into 4 categories according to the ETHICUS II study protocol: withholding or withdrawing life-sustaining therapy, active shortening of the dying process, failed cardiopulmonary resuscitation and patients with brain death.

RESULTS

A total of 795 patients were analyzed; 129 patients died after CPR, 129 developed brain death. LLST was decided in 537 patients, 485 died in the ICU, 90.3%. The mean age was 66.19 years ± 14.36, 63.8% of male patients. In 221 (41%) it was decided to withdraw life-sustaining treatments and in 316 (59%) withholding life-sustaining treatments. Nineteen patients (2.38%) had advance living directives.

CONCLUSIONS

The predominant clinical profile when LTSV was established was male patients over 65 years with mostly cardiovascular comorbidity. We observed that survival was higher in LLST decisions involving withholding of treatments compared to those in which withdrawal was decided. Spain has played a leading role in both patient and ICU recruitment participating in this worldwide multicenter study.

Semiotics of ICU Physicians' Views on End-of-life Care and Quality of Dying in a Critical Care Setting: A Qualitative Study

Background and aim

While intensive care unit (ICU) mortality rates in India are higher when compared to countries with more resources, fewer patients with clinically futile conditions are subjected to limitation of life-sustaining treatments or given access to palliative care. Although a few surveys and audits have been conducted exploring this phenomenon, the qualitative perspectives of ICU physicians regarding end-of-life care (EOLC) and the quality of dying are yet to be explored.

Methods

There are 22 eligible consultant-level ICU physicians working in multidisciplinary ICUs were purposively recruited and interviewed. The study data was analyzed using reflexive thematic analysis (RTA) with a critical realist perspective, and the study findings were interpreted using the lens of the semiotic theory that facilitated the development of themes.

Results

About four themes were generated. Intensive care unit physicians perceived the quality of dying as respecting patients' and families' choices, fulfilling their needs, providing continued care beyond death, and ensuring family satisfaction. To achieve this, the EOLC process must encompass timely decision-making, communication, treatment guidelines, visitation rights, and trust-building. The contextual challenges were legal concerns, decision-making complexities, cost-related issues, and managing expectations. To improve care, ICU physicians suggested amplifying patient and family voices, building therapeutic relationships, mitigating conflicts, enhancing palliative care services, and training ICU providers in EOLC.

Conclusion

Effective management of critically ill patients with life-limiting illnesses in ICUs requires a holistic approach that considers the complex interplay between the EOLC process, its desired outcome, the quality of dying, care context, and the process of meaning-making by ICU physicians.

Predictors and outcomes of withholding and withdrawal of life-sustaining treatments in intensive care units in Singapore: a multicentre observational study

BACKGROUND

Clinical practice guidelines on limitation of life-sustaining treatments (LST) in the intensive care unit (ICU), in the form of withholding or withdrawal of LST, state that there is no ethical difference between the two. Such statements are not uniformly accepted worldwide, and there are few studies on LST limitation in Asia. This study aimed to evaluate the predictors and outcomes of withholding and withdrawal of LST in Singapore, focusing on the similarities and differences between the two approaches.

METHODS

This was a multicentre observational study of patients admitted to 21 adult ICUs across 9 public hospitals in Singapore over an average of three months per year from 2014 to 2019. The primary outcome measures were withholding and withdrawal of LST (cardiopulmonary resuscitation, invasive mechanical ventilation, and vasopressors/inotropes). The secondary outcome measure was hospital mortality. Multivariable generalised mixed model analysis was used to identify independent predictors for withdrawal and withholding of LST and if LST limitation predicts hospital mortality.

RESULTS

There were 8907 patients and 9723 admissions. Of the former, 80.8% had no limitation of LST, 13.0% had LST withheld, and 6.2% had LST withdrawn. Common independent predictors for withholding and withdrawal were increasing age, absence of chronic kidney dialysis, greater dependence in activities of daily living, cardiopulmonary resuscitation before ICU admission, higher Acute Physiology and Chronic Health Evaluation (APACHE) II score, and higher level of care in the first 24 h of ICU admission. Additional predictors for withholding included being of Chinese race, the religions of Hinduism and Islam, malignancy, and chronic liver failure. The additional predictor for withdrawal was lower hospital paying class (with greater government subsidy for hospital bills). Hospital mortality in patients without LST limitation, with LST withholding, and with LST withdrawal was 10.6%, 82.1%, and 91.8%, respectively (p < 0.001). Withholding (odds ratio 13.822, 95% confidence interval 9.987-19.132) and withdrawal (odds ratio 38.319, 95% confidence interval 24.351-60.298) were both found to be independent predictors of hospital mortality on multivariable analysis.

CONCLUSIONS

Differences in the independent predictors of withholding and withdrawal of LST exist. Even after accounting for baseline characteristics, both withholding and withdrawal of LST independently predict hospital mortality. Later mortality in patients who had LST withdrawn compared to withholding suggests that the decision to withdraw may be at the point when medical futility is recognised.

Ventilator Weaning in Prolonged Mechanical Ventilation-A Narrative Review

Patients requiring mechanical ventilation (MV) beyond 21 days, usually referred to as prolonged MV, represent a unique group with significant medical needs and a generally poor prognosis. Research suggests that approximately 10% of all MV patients will need prolonged ventilatory care, and that number will continue to rise. Although we have extensive knowledge of MV in the acute care setting, less is known about care in the post-ICU setting. More than 50% of patients who were deemed unweanable in the ICU will be liberated from MV in the post-acute setting. Prolonged MV also presents a challenge in care for medically complex, elderly, socioeconomically disadvantaged and marginalized individuals, usually at the end of their life. Patients and their families often rely on ventilator weaning facilities and skilled nursing homes for the continuation of care, but home ventilation is becoming more common. The focus of this review is to discuss recent advances in the weaning strategies in prolonged MV, present their outcomes and provide insight into the complexity of care.

Indian Society of Critical Care Medicine and Indian Association of Palliative Care Expert Consensus and Position Statements for End-of-life and Palliative Care in the Intensive Care Unit

End-of-life care (EOLC) exemplifies the joint mission of intensive and palliative care (PC) in their human-centeredness. The explosion of technological advances in medicine must be balanced with the culture of holistic care. Inevitably, it brings together the science and the art of medicine in their full expression. High-quality EOLC in the ICU is grounded in evidence, ethical principles, and professionalism within the framework of the Law. Expert professional statements over the last two decades in India were developed while the law was evolving. Recent landmark Supreme Court judgments have necessitated a review of the clinical pathway for EOLC outlined in the previous statements. Much empirical and interventional evidence has accumulated since the position statement in 2014. This iteration of the joint Indian Society of Critical Care Medicine-Indian Association of Palliative Care (ISCCM-IAPC) Position Statement for EOLC combines contemporary evidence, ethics, and law for decision support by the bedside in Indian ICUs.

Treatment-limiting decisions in patients with severe traumatic brain injury in the Netherlands

Introduction

Treatment-limiting decisions (TLDs) can be inevitable severe traumatic brain injury (s-TBI) patients, but data on their use remain scarce.

Research question

To investigate the prevalence, timing and considerations of TLDs in s-TBI patients.

Material and methods

s-TBI patients between 2008 and 2017 were analysed retrospecively. Patient data, timing, location, involvement of proxies, and reasons for TLDs were collected. Baseline characteristics and in-hospital outcomes were compared between s-TBI patients with and without TLDs.

Results

TLDs were reported in 117 of 270 s-TBI patients (43.3%) and 95.9% of deaths after s-TBI were preceded by a TLD. The majority of TLDs (68.4%) were categorized as withdrawal of therapy, of which withdrawal of organ-support in 64.1%. Neurosurgical intervention was withheld in 29.9%. The median time from admission to TLD was 2 days [IQR, 0-8] and 50.4% of TLDs were made within 3 days of admission. The main reason for a TLD was that the patients were perceived as unsalvageable (66.7%). Nearly all decisions were made multidisciplinary (99.1%) with proxies involvement (75.2%). The predicted mortality (CRASH-score) between patients with and without TLDs were 72.6 vs. 70.6%. The percentage of TLDs in s-TBI patients increased from 20.0% in 2008 to 42.9% in 2012 and 64.3% in 2017.

Discussion and conclusion

TLDs occurred in almost half of s-TBI patients and were instituted more frequently over time. Half of TLDs were made within 3 days of admission in spite of baseline prognosis between groups being similar. Future research should address whether prognostic nihilism contributes to self-fulfilling prophecies.

The Complex Dynamics of Decision-Making at the End of Life in the Intensive Care Unit: A Systematic Review of Stakeholders' Views and Influential Factors

A lack of consensus resulting in severe conflicts is often observed between the stakeholders regarding their respective roles in end-of-life (EOL) decision-making in the ICU. Since the burden of these decisions lies upon the individuals, their opinions must be known by medical, judicial, legislative, and governmental authorities. Part of the solution to the issues that arise would be to examine and understand the views of the people in different societies. Hence, in this systematic review, we assessed the attitudes of the physicians, nurses, families, and the general public toward who should be involved in decision-making and influencing factors. Toward this, we searched three electronic databases, i.e., PubMed, CINAHL (Cumulative Index to Nursing & Allied Health), and Embase. A matrix was developed, discussed, accepted, and used for data extraction by two independent investigators. Study quality was evaluated using the Newcastle-Ottawa Scale. Data were extracted by one researcher and double-checked by a second one, and any discrepancies were discussed with a third researcher. The data were analyzed descriptively and synthesized according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Thirty-three studies met our inclusion criteria. Most involved healthcare professionals and reported geographic variations in different timeframes. While paternalistic features have been observed, physicians overall showed an inclination toward collaborative decision-making. Correspondingly, the nursing staff, families, and the public are aligned toward patient and relatives' participation, with nurses expressing their own involvement as well. Six categories of influencing factors were identified, with high-impact factors, including demographics, fear of litigation, and regulation-related ones. Findings delineate three key points. Firstly, overall stakeholders' perspectives toward EOL decision-making in the ICU seem to be leaning toward a more collaborative decision-making direction. Secondly, to reduce conflicts and reach a consensus, multifaceted efforts are needed by both healthcare professionals and governmental/regulatory authorities. Finally, due to the multifactorial complexity of the subject, directly related to demographic and regulatory factors, these efforts should be more extensively sought at a regional level.

Competencies of the nurses in the limitation of therapeutic effort in the intensive care unit: An integrative review

Objective

Nurses inevitably encounter patients who require care aimed at limiting therapeutic effort (LTE), even though many of them are not prepared to provide support to individuals with terminal illnesses and their families. One of the contexts in which the LTE is considered is the intensive care unit (ICU). This review is to describe the competencies for the execution of a nursing professional role in the LTE in the ICU.

Method

An integrative review of the literature published between the years 2010 and 2023. The search was carried out in five databases: Medline, Wiley Online Library, SciELO, ScienceDirect, and Web of Science. The Critical Appraisal Skills Programme in Spanish was used as the template for study evaluation. The methodology of the Oxford Center for Evidence-Based Medicine (CEBM) was used to assess the level of evidence and the degree of recommendation.

Result

A total of 25 articles in a wide range of studies were included. The findings suggest that the competencies for LTE in the ICU are direct patient care, family-centered care, and the role of the nurse within the team. However, more high-quality studies are needed to confirm these conclusions. Three categories were identified: (a) competencies as defender agent between the patient, his family, and the interdisciplinary team; (b) competencies for decision-making in limiting the therapeutic effort; and (c) competencies for nursing therapeutic interventions at the end of life.

Conclusion

The competencies of the nursing professionals who work in the adult ICU in the LTE are essential to the patient's quality of life, dignity of their death, and comprehensive family support for coping with grief.

Determinants of 90-day case fatality among older patients admitted to intensive care units: A retrospective cohort study

BACKGROUND

A recent systematic review identified highly variable case-fatality rates among studies of older patients admitted to intensive care units (ICUs). However, structural and process determinants including patient resident status, tertiary ICU status, and treatment limitations were unavailable.

OBJECTIVE

The objective of this study was to evaluate the role of determinants such as resident status, tertiary ICU, and treatment limitations on 90-day case fatality among older ICU patients.

METHODS

A retrospective cohort of all Queensland residents aged 75 years and older admitted to four ICUs within the Metro North Hospital and Health Service was included. The impact of Metro North Hospital and Health Service resident status, tertiary ICU, treatment limitations, and other known determinants on 90-day all-cause case fatality (case-fatality) was assessed.

RESULTS

Of the 2144 eligible first admissions included, 1365 were residents, and 893 were nonelective admissions. The case-fatality rates were higher in residents (21% vs 12%, p < 0.001), nonelective admissions (32% vs 7%, p < 0.001), and non-tertiary ICU admissions (27% vs 16%, p < 0.001). The case fatality increased progressively with age, being highest (29.6%) in the >90 years age-group. Multivariable mixedeffects logistic regression modelling demonstrated that presence of treatment limitations was strongly associated with case fatality, but neither resident status nor the tertiary ICU was associated.

CONCLUSION

The presence of treatment limitations should be considered when evaluating variations in case fatality among cohorts of older ICU patients, in addition to variables with well-established association with case fatality such as comorbidities and illness severity.

Palliative Care in Severe Neurotrauma Patients in the Intensive Care Unit

Traumatic brain injury (TBI) is a significant cause of mortality and morbidity worldwide and many patients with TBI require intensive care unit (ICU) management. When facing a life-threatening illness, such as TBI, a palliative care approach that focuses on noncurative aspects of care should always be considered in the ICU. Research shows that neurosurgical patients in the ICU receive palliative care less frequently than the medical patients in the ICU, which is a missed opportunity for these patients. However, providing appropriate palliative care to neurotrauma patients in an ICU can be difficult, particularly for young adult patients. The patients' prognoses are often unclear, the likelihood of advance directives is small, and the bereaved families must act as decision-makers. This article highlights the different aspects of the palliative care approach as well as barriers and challenges that accompany the TBI patient population, with a particular focus on young adult patients with TBI and the role of their family members. The article concludes with recommendations for physicians for effective and adequate communication to successfully implement the palliative care approach into standard ICU care and to improve quality of care for patients with TBI and their families.

End-of-life practices in 11 German intensive care units : Results from the ETHICUS-2 study

BACKGROUND

End-of-life care is common in German intensive care units (ICUs) but little is known about daily practice.

OBJECTIVES

To study the practice of end-of-life care.

METHODS

Prospectively planned, secondary analysis comprising the German subset of the worldwide Ethicus‑2 Study (2015-2016) including consecutive ICU patients with limitation of life-sustaining therapy or who died.

RESULTS

Among 1092 (13.7%) of 7966 patients from 11 multidisciplinary ICUs, 967 (88.6%) had treatment limitations, 92 (8.4%) died with failed CPR, and 33 (3%) with brain death. Among patients with treatment limitations, 22.3% (216/967) patients were discharged alive from the ICU. More patients had treatments withdrawn than withheld (556 [57.5%] vs. 411 [42.5%], p < 0.001). Patients with treatment limitations were older (median 73 years [interquartile range (IQR) 61-80] vs. 68 years [IQR 54-77]) and more had mental decision-making capacity (12.9 vs. 0.8%), advance directives (28.6 vs. 11.2%), and information about treatment wishes (82.7 vs 33.3%, all p < 0.001). Physicians reported discussing treatment limitations with patients with mental decision-making capacity and families (91.3 and 82.6%, respectively). Patient wishes were unknown in 41.3% of patients. The major reason for decision-making was unresponsiveness to maximal therapy (34.6%).

CONCLUSIONS

Treatment limitations are common, based on information about patients' wishes and discussion between stakeholders, patients and families. However, our findings suggest that treatment preferences of nearly half the patients remain unknown which affects guidance for treatment decisions.

Ethical issues encountered by French intensive care unit caregivers during the first COVID-19 outbreak

PURPOSE

We aimed to describe the ethical issues encountered by health care workers during the first COVID-19 outbreak in French intensive care units (ICUs), and the factors associated with their emergence.

METHODS

This descriptive multicentre survey study was conducted by distributing a questionnaire to 26 French ICUs, from 1 June to 1 October 2020. Physicians, residents, nurses, and orderlies who worked in an ICU during the first COVID-19 outbreak were included. Multiple logistic regression models were performed to identify the factors associated with ethical issues.

RESULTS

Among the 4,670 questionnaires sent out, 1,188 responses were received, giving a participation rate of 25.4%. Overall, 953 participants (80.2%) reported experiencing issue(s) while caring for patients during the first COVID-19 outbreak. The most common issues encountered concerned the restriction of family visits in the ICU (91.7%) and the risk of contamination for health care workers (72.3%). Nurses and orderlies faced this latter issue more than physicians (adjusted odds ratio [ORa], 2.98; 95% confidence interval [CI], 1.87 to 4.76; P < 0.001 and ORa, 4.35; 95% CI, 2.08 to 9.12; P < 0.001, respectively). They also faced more the issue "act contrary to the patient's advance directives" (ORa, 4.59; 95% CI, 1.74 to 12.08; P < 0.01 and ORa, 10.65; 95% CI, 3.71 to 30.60; P < 0.001, respectively). A total of 1,132 (86.9%) respondents thought that ethics training should be better integrated into the initial training of health care workers.

CONCLUSION

Eight out of ten responding French ICU health care workers experienced ethical issues during the first COVID-19 outbreak. Identifying these issues is a first step towards anticipating and managing such issues, particularly in the context of potential future health crises.

The impact of religion on changes in end-of-life practices in European intensive care units: a comparative analysis over 16 years

PURPOSE

Religious beliefs affect end-of-life practices in intensive care units (ICUs). Changes over time in end-of-life practices were not investigated regarding religions.

METHODS

Twenty-two European ICUs (3 regions: Northern, Central, and Southern Europe) participated in both Ethicus-1 (years 1999-2000) and Ethicus-2 studies (years 2015-2016). Data of ICU patients who died or had limitations of life-sustaining therapy were analysed regarding changes in end-of-life practices and patient/physician religious affiliations. Frequencies, timing of decision-making, and religious affiliations of physicians/patients were compared using the same definitions.

RESULTS

In total, 4592 adult ICU patients (n = 2807 Ethicus-1, n = 1785 Ethicus-2) were analysed. In both studies, patient and physician religious affiliations were mostly Catholic, Greek Orthodox, Jewish, Protestant, or unknown. Treating physicians (but not patients) commonly reported no religious affiliation (18%). Distribution of end-of-life practices with respect to religion and geographical regions were comparable between the two studies. Withholding [n = 1143 (40.7%) Ethicus-1 and n = 892 (50%) Ethicus-2] and withdrawing [n = 695 (24.8%) Ethicus-1 and n = 692 (38.8%) Ethicus-2] were most commonly decided. No significant changes in end-of-life practices were observed for any religion over 16 years. The number of end-of-life discussions with patients/ families/ physicians increased, while mortality and time until first decision decreased.

CONCLUSIONS

Changes in end-of-life practices observed over 16 years appear unrelated to religious affiliations of ICU patients or their treating physicians, but the effects of religiosity and/or culture could not be assessed. Shorter time until decision in the ICU and increased numbers of patient and family discussions may indicate increased awareness of the importance of end-of-life decision-making in the ICU.

Evidence Guiding Withdrawal of Mechanical Ventilation at the End of Life: A Review

OBJECTIVE

Distress at the end of life in the intensive care unit (ICU) is common. We reviewed the evidence guiding symptom assessment, withdrawal of mechanical ventilation (WMV) process, support for the ICU team, and symptom management among adults, and specifically older adults, at end of life in the ICU.

SETTING AND DESIGN

Systematic search of published literature (January 1990-December 2021) pertaining to WMV at end of life among adults in the ICU setting using PubMed, Embase, and Web of Science. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed.

PARTICIPANTS

Adults (age 18 and over) undergoing WMV in the ICU.

MEASUREMENTS

Study quality was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.

RESULTS

Out of 574 articles screened, 130 underwent full text review, and 74 were reviewed and assessed for quality. The highest quality studies pertained to use of validated symptom scales during WMV. Studies of the WMV process itself were generally lower quality. Support for the ICU team best occurs via structured communication and social supports. Dyspnea is the most distressing symptom, and while high quality evidence supports the use of opiates, there is limited evidence to guide implementation of their use for specific patients.

CONCLUSION

High quality studies support some practices in palliative WMV, while gaps in evidence remain for the WMV process, supporting the ICU team, and medical management of distress. Future studies should rigorously compare WMV processes and symptom management to reduce distress at end of life.

Culture, ethnicity, and socio-economic status as determinants of the management of patients with advanced heart failure who need palliative care: A clinical consensus statement from the Heart Failure Association (HFA) of the ESC, the ESC Patient Forum, and the European Association of Palliative Care

The delivery of effective healthcare entails the configuration and resourcing of health economies to address the burden of disease, including acute and chronic heart failure, that affects local populations. Increasing migration is leading to more multicultural and ethnically diverse societies worldwide, with migration research suggesting that minority populations are often subject to discrimination, socio-economic disadvantage, and inequity of access to optimal clinical support. Within these contexts, the provision of person-centred care requires medical and nursing staff to be aware of and become adept in navigating the nuances of cultural diversity, and how that can impact some individuals and families entrusted to their care. This paper will examine current evidence, provide practical guidance, and signpost professionals on developing cultural competence within the setting of patients with advanced heart failure who may benefit from palliative care.

Clinical spectrum and prognostic impact of cancer in critically ill patients with HIV: a multicentre cohort study

BACKGROUND

Both AIDS-defining and non-AIDS-defining cancers (ADC/NADC) predispose people living with HIV (PLHIV) to critical illnesses. The objective of this multicentre study was to investigate the prognostic impact of ADC and NADC in PLHIV admitted to the intensive care unit (ICU).

METHODS

All PLHIV admitted over the 2015-2020 period in 12 university-affiliated ICUs in France were included in the study cohort. The effect of ADC and NADC on in-hospital mortality (primary study endpoint) was measured through logistic regression with augmented backward elimination of potential independent variables. The association between ADC/NADC and treatment limitation decision (TLD) during the ICU stay (secondary study endpoint) was analysed. One-year mortality in patients discharged alive from the index hospital admission (exploratory study endpoint) was compared between those with ADC, NADC or no cancer.

RESULTS

Amongst the 939 included PLHIV (median age, 52 [43-59] years; combination antiretroviral therapy, 74.4%), 97 (10.3%) and 106 (11.3%) presented with an active NADC (mostly lung and intestinal neoplasms) and an active ADC (predominantly AIDS-defining non-Hodgkin lymphoma), respectively. Inaugural admissions were common. Bacterial sepsis and non-infectious neoplasm-related complications accounted for most of admissions in these subgroups. Hospital mortality was 12.4% in patients without cancer, 30.2% in ADC patients and 45.4% in NADC patients (P < 0.0001). NADC (adjusted odds ratio [aOR], 7.00; 95% confidence interval [CI], 4.07-12.05) and ADC (aOR, 3.11; 95% CI 1.76-5.51) were independently associated with in-hospital death after adjustment on severity and frailty markers. The prevalence of TLD was 8.0% in patients without cancer, 17.9% in ADC patients and 33.0% in NADC patients (P < 0.0001)-organ failures and non-neoplastic comorbidities were less often considered in patients with cancer. One-year mortality in survivors of the index hospital admission was 7.8% in patients without cancer, 17.0% in ADC patients and 33.3% in NADC patients (P < 0.0001).

CONCLUSIONS

NADC and ADC are equally prevalent, stand as a leading argument for TLD, and strongly predict in-hospital death in the current population of PLHIV requiring ICU admission.

Withholding or withdrawing life-sustaining treatments in the COVID-19 pandemic: adherence to legal standards

OBJECTIVES

In France, when the patient is unable to express his wishes, the decision to withhold or withdraw life-sustaining treatment (WWLST) is made following a collegial procedure described by a law. The aim of our study was to assess how closely this WWLST decision-making procedure in end of life patients was maintained during the COVID-19 pandemic.

METHODS

This retrospective observational multicentre study compared the rate of non-compliance with WWLST decision-making procedures during the pandemic period from March to June 2020 with control period in 2019, in Clermont-Ferrand and Lyon Hospitals. Secondary objectives were to determine the factors associated with non-compliance.

RESULTS

In 430 deceased patients included (176 in 2019 and 254 in 2020), the rate of non-compliance was 61.4% in 2019 and 59.1% in 2020 (p=0.63). In multivariable analysis, non-compliance was associated with immunosuppression status (OR 1.69, 95% CI (1.12 to 2.54), p=0.01) but was lower in intensive care unit (OR 0.54, 95% CI (0.36 to 0.82), p=0.003) and when the patient had visits from relatives (OR 0.41, 95% CI (0.22 to 0.75), p=0.004).

CONCLUSION

In France, more than half of WWLST decisions do not comply with the law. The COVID-19 pandemic did not increase this non-compliance rate. Further studies are needed for a better understanding of the mechanisms underlying non-compliance with WWLST decision-making procedure.

In this article, the authors review the origins of palliative care within the critical care context and describe the evolution of symptom management, shared decision-making, and comfort-focused care in the ICU from the 1970s to the early 2000s. The authors also review the growth of interventional studies in the past 20 years and indicate areas for future study and quality improvement for end-of-life care among the critically ill.

International variability in the diagnosis and management of disorders of consciousness

This manuscript explores the international variability in the diagnosis and management of disorders of consciousness (DoC). The identification, evaluation, intervention, exploration, prognostication and limitation of therapy for patients with DoC is reviewed through an international lens. The myriad factors that impact the diagnosis and management of DoC including 1) financial, 2) legal and regulatory, 3) cultural, 4) religious and 5) psychosocial considerations are discussed. As data comparing patients with DoC internationally are limited, findings from the general critical care or neurocritical care literature are described when information specific to patients with DoC is unavailable. There is a need for improvements in clinical care, education, advocacy and research related to patients with DoC worldwide. It is imperative to standardize methodology to evaluate consciousness and prognosticate outcome. Further, education is needed to 1) generate awareness of the impact of the aforementioned considerations on patients with DoC and 2) develop techniques to optimize communication about DoC with families. It is necessary to promote equity in access to expertise and resources for patients with DoC to enhance the care of patients with DoC worldwide. Improving understanding and management of patients with DoC requires harmonization of existing datasets, development of registries where none exist and establishment of international clinical trial networks that include patients in all phases along the spectrum of care. The work of international organizations like the Curing Coma Campaign can hopefully minimize international variability in the diagnosis and management of DoC and optimize care.

Moral distress among intensive care unit professions in the UK: a mixed-methods study

OBJECTIVE

To assess the experience of moral distress among intensive care unit (ICU) professionals in the UK.

DESIGN

Mixed methods: validated quantitative measure of moral distress followed by purposive sample of respondents who underwent semistructured interviews.

SETTING

Four ICUs of varying sizes and specialty facilities.

PARTICIPANTS

Healthcare professionals working in ICU.

RESULTS

227 questionnaires were returned and 15 interviews performed. Moral distress occurred across all ICUs and professional demographics. It was most commonly related to providing care perceived as futile or against the patient's wishes/interests, followed by resource constraints compromising care. Moral distress score was independently influenced by profession (p=0.02) (nurses 117.0 vs doctors 78.0). A lack of agency was central to moral distress and its negative experience could lead to withdrawal from engaging with patients/families. One-third indicated their intention to leave their current post due to moral distress and this was greater among nurses than doctors (37.0% vs 15.0%). Moral distress was independently associated with an intention to leave their current post (p<0.0001) and a previous post (p=0.001). Participants described a range of individualised coping strategies tailored to the situations faced. The most common and highly valued strategies were informal and relied on working within a supportive environment along with a close-knit team, although participants acknowledged there was a role for structured and formalised intervention.

CONCLUSIONS

Moral distress is widespread among UK ICU professionals and can have an important negative impact on patient care, professional wellbeing and staff retention, a particularly concerning finding as this study was performed prior to the COVID-19 pandemic. Moral distress due to resource-related issues is more severe than comparable studies in North America. Interventions to support professionals should recognise the individualistic nature of coping with moral distress. The value of close-knit teams and supportive environments has implications for how intensive care services are organised.

Striving to Keep a Clear Conscience by Going Above and Beyond: The Experiences of Intensive Care Unit Nurses

Working as a nurse in the critical care unit may involve ethical challenges including conflict of conscience. Literature provides very limited knowledge about intensive care unit (ICU) nurses' perception of conscience. Considering the influence of culture on the perception of conscience, it is important to study it in diverse contexts. This study aims were to explore the meaning of conscience and the impact of conscience on nurses' practice in the ICU. A qualitative research approach was used to answer the research question, and qualitative content analysis guided the study. A total of 17 interviews were conducted with ICU nurses. Data were collected through semistructured tools by using videoconferencing and face-to-face interviews. Data analysis resulted in the formation of 2 main categories and 7 subcategories. The main categories included understanding the conscience and unlimited efforts in caretaking as the path to a clear conscience. The category of understanding the conscience includes 3 subcategories of conscience as an intrinsic asset and internal observer, dynamicity of conscience, and conscience as the cornerstone of morality. Also, the category of unlimited efforts in caretaking as the path to a clear conscience consists of 4 subcategories including giving full attention to the patient, putting oneself in another's shoes, taking responsibility, and working beyond the job description. Conscience plays an essential role in providing the ethical care among ICU nurses. The ICU nurses felt that they need to go above and beyond to keep their conscience clear. Nurses expressed the importance of following the call of conscience at their workplace, which demanded unlimited efforts to achieve a clear conscience.

Limitation of life-sustaining therapies in critically ill patients with COVID-19: a descriptive epidemiological investigation from the COVID-ICU study

BACKGROUND

Limitations of life-sustaining therapies (LST) practices are frequent and vary among intensive care units (ICUs). However, scarce data were available during the COVID-19 pandemic when ICUs were under intense pressure. We aimed to investigate the prevalence, cumulative incidence, timing, modalities, and factors associated with LST decisions in critically ill COVID-19 patients.

METHODS

We did an ancillary analysis of the European multicentre COVID-ICU study, which collected data from 163 ICUs in France, Belgium and Switzerland. ICU load, a parameter reflecting stress on ICU capacities, was calculated at the patient level using daily ICU bed occupancy data from official country epidemiological reports. Mixed effects logistic regression was used to assess the association of variables with LST limitation decisions.

RESULTS

Among 4671 severe COVID-19 patients admitted from February 25 to May 4, 2020, the prevalence of in-ICU LST limitations was 14.5%, with a nearly six-fold variability between centres. Overall 28-day cumulative incidence of LST limitations was 12.4%, which occurred at a median of 8 days (3-21). Median ICU load at the patient level was 126%. Age, clinical frailty scale score, and respiratory severity were associated with LST limitations, while ICU load was not. In-ICU death occurred in 74% and 95% of patients, respectively, after LST withholding and withdrawal, while median survival time was 3 days (1-11) after LST limitations.

CONCLUSIONS

In this study, LST limitations frequently preceded death, with a major impact on time of death. In contrast to ICU load, older age, frailty, and the severity of respiratory failure during the first 24 h were the main factors associated with decisions of LST limitations.

Machine learning determination of motivators of terminal extubation during the transition to end-of-life care in intensive care unit

Procedural aspects of compassionate care such as the terminal extubation are understudied. We used machine learning methods to determine factors associated with the decision to extubate the critically ill patient at the end of life, and whether the terminal extubation shortens the dying process. We performed a secondary data analysis of a large, prospective, multicentre, cohort study, death prediction and physiology after removal of therapy (DePPaRT), which collected baseline data as well as ECG, pulse oximeter and arterial waveforms from WLST until 30 min after death. We analysed a priori defined factors associated with the decision to perform terminal extubation in WLST using the random forest method and logistic regression. Cox regression was used to analyse the effect of terminal extubation on time from WLST to death. A total of 616 patients were included into the analysis, out of which 396 (64.3%) were terminally extubated. The study centre, low or no vasopressor support, and good respiratory function were factors significantly associated with the decision to extubate. Unadjusted time to death did not differ between patients with and without extubation (median survival time extubated vs. not extubated: 60 [95% CI: 46; 76] vs. 58 [95% CI: 45; 75] min). In contrast, after adjustment for confounders, time to death of extubated patients was significantly shorter (49 [95% CI: 40; 62] vs. 85 [95% CI: 61; 115] min). The decision to terminally extubate is associated with specific centres and less respiratory and/or vasopressor support. In this context, terminal extubation was associated with a shorter time to death.
