End-of-Life Care in ICUs in East Asia: A Comparison Among China, Korea, and Japan

Issues and implications of the life-sustaining treatment decision act: comparing the data from the survey and clinical data of inpatients at the end-of-life process

BACKGROUND

Health professionals had difficulty choosing the right time to discuss life-sustaining treatments (LSTs) since the Korean Act was passed in 2018.

OBJECTIVE

This study aimed to understand how patients decide to undergo LSTs in clinical practice and to compare the perceptions of these decisions among health professionals, patients, and families with suggestions to support the self-directed decisions of patients.

RESEARCH DESIGN

A retrospective observational study with electronic medical records (EMRs) and a descriptive survey was used.

METHODS

The data obtained from the EMRs included all adult patients who died in end-of-life care at a university hospital in 2021. We also conducted a survey of 214 health professionals and 100 patients and their families (CNUH IRB approval no. 2022-07-006).

RESULTS

Based on the EMR data of 916 patients in end-of-life care, 78.4% signed do-not-attempt-resuscitation consents, 5.6% completed the documents for LSTs, and 10.2% completed both forms. LST decisions were mostly made by family members (81.5%). Most survey participants agreed that meaningless LSTs should be suspended, and the decision should be made by patients. Patients and family members (42-56%) and health professionals (56-58%) recommended discussing LST suspension when the patient is still conscious but with predicted deterioration of their condition. The suffering experienced by the patient was considered to be a priority by most patients (58%) and families (54%) during the decision-making process, while health professionals considered "the possibility of the patient's recovery" to be the highest priority (43-55%).

CONCLUSIONS

There is still a significant discrepancy in the perceptions of LST decisions among health professionals, patients, and their families despite high awareness of the Act. This situation makes it challenging to implement the Act to ensure respect for the rights of patients to self-determination and dignified end-of-life. Further effort is needed to improve the awareness of LSTs and to clarify the ambiguity of document preparation timing.

Assessing palliative care practices in intensive care units and interpreting them using the lens of appropriate care concepts. An umbrella review

PURPOSE

Intensive care units (ICUs) have significant palliative care needs but lack a reliable care framework. This umbrella review addresses them by synthesising palliative care practices provided at end-of-life to critically ill patients and their families before, during, and after ICU admission.

METHODS

Seven databases were systematically searched for systematic reviews, and the umbrella review was conducted according to the guidelines laid out by the Joanna Briggs Institute (JBI).

RESULTS

Out of 3122 initial records identified, 40 systematic reviews were included in the synthesis. Six key themes were generated that reflect the palliative and end-of-life care practices in the ICUs and their outcomes. Effective communication and accurate prognostications enabled families to make informed decisions, cope with uncertainty, ease distress, and shorten ICU stays. Inter-team discussions and agreement on a plan are essential before discussing care goals. Recording care preferences prevents unnecessary end-of-life treatments. Exceptional end-of-life care should include symptom management, family support, hydration and nutrition optimisation, avoidance of unhelpful treatments, and bereavement support. Evaluating end-of-life care quality is critical and can be accomplished by seeking family feedback or conducting a survey.

CONCLUSION

This umbrella review encapsulates current palliative care practices in ICUs, influencing patient and family outcomes and providing insights into developing an appropriate care framework for critically ill patients needing end-of-life care and their families.

Perception of diagnosis by family caregivers in severe brain injury patients in China

OBJECTIVES

Surrogate decision-making by family caregivers for patients with severe brain injury is influenced by the availability and understanding of relevant information and expectations for future rehabilitation. We aimed to compare the consistency of family caregivers' perceptions with clinical diagnoses and to inform their expectation of prognosis in the future.

METHODS

The Coma Recovery Scale-Revised was used to assess the diagnosis of inpatients with severe brain injury between February 2019 and February 2020. A main family caregiver was included per patient. The family caregiver's perception of the patient's consciousness and expectations of future recovery were collected through questionnaires and compared consistently with the clinical diagnosis.

RESULTS

The final sample included 101 main family caregivers of patients (57 UWS, unresponsive wakefulness syndrome, 37 MCS, minimally conscious state, 7 EMCS, emergence from MCS) with severe brain injury. Only 57 family caregivers correctly assessed the level of consciousness as indicated by the CRS-R, showing weak consistency (Kappa = 0.217, P = 0.002). Family caregivers' demographic characteristics and CRS-R diagnosis influenced the consistency between perception and clinical diagnosis. Family caregivers who provided hands-on care to patients showed higher levels of consistent perception (AOR = 12.24, 95% CI = 2.06-73.00, P = 0.006). Compared to UWS, the family caregivers of MCS patients were more likely to have a correct perception (OR = 7.68, 95% CI = 1.34-44.06). Family caregivers had positive expectations for patients' recovery in terms of both communication and returning to normal life.

CONCLUSION

Nearly half of family caregivers have inadequate understanding of their relative's level of consciousness, and most of them report overly optimistic expectations that do not align with clinical diagnosis. Providing more medical information to family caregivers to support their surrogate decision-making process is essential.

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.

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.

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.

End-of-Life Communication Skills Training for Undergraduate Nursing Students to Address Cultural Obstacles in China

Nurses face many difficulties and challenges related to how patients and their families deal with communication about end-of-life (EOL) care in China because of the strong influence of traditional Chinese culture. Moreover, education and training opportunities in EOL communication skills for nursing students are rare in mainland China. This study designed a progressive case involving a common EOL communication dilemma related to traditional Chinese culture and trained 50 undergraduate nursing students in EOL communication skills. A quasi-experimental design was used to compare the training outcomes of nursing students who were divided into a standardized patient simulation group and a role-playing group. The role-playing group (23 participants) was trained via group case discussion and role-playing among classmates, while the standardized patient simulation group (27 participants) completed EOL communication training by interacting with standardized patients and their families in a high-fidelity simulation. Attitudes toward death, self-confidence in EOL communication, and communication learning were evaluated in both groups during preintervention and postintervention. The results showed that all 3 variables improved after the intervention. This study shows that EOL communication skills training has a positive effect on nursing students to a certain extent.

Ethical Healthcare Attitudes of Japanese Citizens and Physicians: Patient-Centered or Family-Centered?

BACKGROUND

In current Western medical ethics, patient-centered medicine is considered the norm. However, the cultural background of collectivism in East Asia often leads to family-centered decision-making. In Japan, prior studies have reported that family-centered decision-making is more likely to be preferred in situations of disease notification and end-of-life decision-making. Nonetheless, there has been a recent shift from collectivism to individualism due to changes in the social structure. Various personal factors have also been reported to influence moral decision-making. Therefore, this study examined whether the current trend in attitudes of healthcare decision-making in Japan is family-centered or patient-centered among the general public and physicians. In addition, the personal factors that influence this tendency were examined.

METHODS

Three vignettes on disease notification and two vignettes on decision-making during end-of-life care were created, and 457 members of the public and 284 physicians were asked about their attitudes (behavioral intentions) regarding these vignettes.

RESULTS

Approximately, 95% of physicians were patient-centered in explaining the patient's severe medical condition. However, approximately 80% of physicians emphasized the wishes of the family over patient wishes when making life-sustaining decisions. Nearly half the general public emphasized the patient's wishes in the explanation of a severe medical condition and in life-sustaining decisions. In both the public and physician groups, personal factors, particularly the presence or absence of a disease under treatment and prior caregiving experience, influenced ethical attitudes toward medical treatment decisions.

CONCLUSIONS

In relatively low-conflict situations, such as the announcement of a patient's medical condition, physicians tended to be patient-centered, while they tended to be family-centered in situations of strong conflict in withholding life-sustaining treatment. The fact that personal factors influenced the family-centered response in situations of strong conflict highlights the importance of not only acquiring knowledge of medical ethics but also learning to fairly apply this knowledge in practice.

Nurses' perceptions of barriers and supportive behaviors in end-of-life care in the intensive care unit: a cross-sectional study

BACKGROUND AND AIM

Patient deaths are common in the intensive care unit, and a nurse's perception of barriers to and supportive behaviors in end-of-life care varies widely depending upon their cultural background. The aim of this study was to describe the perceptions of intensive care nurses regarding barriers to and supportive behaviors in providing end-of-life care in a Chinese cultural context.

METHODS

A cross-sectional survey was conducted among intensive care nurses in 20 intensive care units in 11 general hospitals in central and eastern China. Instruments used in this study were general survey and Beckstrand's questionnaire. Data were collected via online survey platform. Descriptive analysis was used to describe general characteristics of participants and mean and standard deviations of the barriers and supportive behaviors. The mean and standard deviation were used to describe the intensity and frequency of each barrier or supportive behavior following Beckstrand's method to calculate the score of barriers and supportive behaviors. Content analysis was used to analyze the responses to open-ended questions.

RESULTS

The response rate was 53% (n = 368/700). Five of the top six barriers related to families and the other was the nurse's lack of time. Supportive behaviors included three related to families and three related to healthcare providers. Nurses in the intensive care unit felt that families should be present at the bedside of a dying patient, there is a need to provide a quiet, independent environment and psychological support should be provided to the patient and family. Nurses believe that if possible, families can be given flexibility to visit dying patients, such as increasing the number of visits, rather than limiting visiting hours altogether. Families need to be given enough time to perform the final rites on the dying patient. Moreover, it is remarkable that nurses' supportive behaviors almost all concern care after death.

CONCLUSIONS

According to ICU-nurses family-related factors, such as accompany of the dying patients and acceptence of patient's imminent death, were found the major factors affecting the quality of end-of-life care. These findings identify the most prominent current barriers and supportive behaviors, which may provide a basis for addressing these issues in the future to improve the quality of end-of-life care.

Efficacy of a Self-Designed Questionnaire for Community Screening of COPD

Purpose

To evaluate the screening efficacy of a self-designed questionnaire for chronic obstructive pulmonary disease (COPD) and the potential gender disparity in its efficacy.

Patients and Methods

A screening questionnaire, the COPD Screening Questionnaire-Minhang (COPD-MH), was designed with reference to the self-scored COPD population screener (COPD-PS) and the COPD screening questionnaire (COPD-SQ), incorporating characteristics of the local population in Shanghai, China. The revised questionnaire included only five questions. Each question scored 0–4, with a highest total score of 20. The COPD-PS and COPD-SQ comprised 5 and 7 questions, respectively. Their scoring criteria were not consecutive integers and, thus, not easily counted. The COPD-MH focused on symptoms, and each item was set the same answers for convenience. Screening for COPD was conducted among residents over 40 years old in a community in Shanghai using the three aforementioned questionnaires. Each participant also received spirometry tests. A receiver operator characteristic (ROC) curve was drawn, and the area under the curve (AUC) was calculated to assess the validity of each questionnaire.

Results

A total of 1197 community residents in Minhang District completed the screening. A total of 1023 participants were finally included in analysis with a detected prevalence of 12.4% for COPD. The best cut-off values for the COPD-PS, COPD-SQ, and COPD-MH were 4, 16, and 7 points, respectively. The AUCs for these three questionnaires were >0.5, but the sensitivity of the COPD-MH was higher than those of the COPD-PS and COPD-SQ. The sensitivity of COPD-MH was 80.77% for males and 77.5% for females. The COPD-MH had higher diagnostic efficiency and higher sensitivity with gender-specific cut-off values.

Conclusion

The COPD-MH is comparable to and less time-consuming than the existing screening methods for COPD. Gender-related factors affect the optimal cut-off values of the COPD screening questionnaire, and rectifying this can improve the practical screening efficacy.

Eleven-year retrospective study characterizing patients with severe brain damage and poor neurological prognosis -role of physicians' attitude toward life-sustaining treatment

Background

Severe brain hemorrhage/infarction and cardiac arrest constitute the most critical situations leading to poor neurological prognosis. Characterization of these patients is required to offer successful end-of-life care, but actual practice is affected by multiple confounding factors, including ethicolegal issues, particular in Japan and Asia. The aim of this study is to evaluate the clinical courses of patients with severe brain damage and to assess the preference of end-of-life care for these patients in Japanese hospitals.

Methods

A retrospective observational study was conducted between 2008 and 2018. All intracranial hemorrhage/infarction and cardiac arrest out-patients (n = 510) who were admitted to our two affiliated hospitals and survived but with poor neurologic outcomes were included. Demographic characteristics as well as prognosis and treatment policies were also assessed.

Results

Patients were divided into two categories; cases with absent brainstem reflex (BSR) (BSR[-]) and those with preserved BSR (BSR[ +]). The survival rate was higher and the length of hospitalization was longer in patients with BSR[ +] than in those with BSR[-]. Among three life-sustaining policies (i.e., aggressive treatment, withdrawal of treatment, and withholding of treatment), withholding of treatment was adopted to most patients. In BSR[-], the proportion of three treatment policies performed at the final decision did not differ from that at the initial diagnosis on neurological status (p = 0.432). In contrast, this proportion tended to be altered in BSR[ +] (p = 0.072), with a decreasing tendency of aggressive treatment and a modest increasing tendency of withdrawal of treatment. Furthermore, the requests from patients’ families to withdraw life-sustaining treatment, including discontinuation of mechanical ventilation, increased, but actual implementation of withdrawal by physicians was less than half of the requests.

Conclusions

BSR constitutes a crucial determinant of mortality and length of hospitalization in comatose patients with severe brain damage. Although the number of withdrawal of life-sustaining treatment tends to increase over time in BSR[ +] patients, there are many more requests from patients’ families for withdrawal. Since physicians has a tendency to desist from withdrawing life-sustaining treatment, more in-depth communication between medical staff and patients’ families will facilitate mutual understanding over ethicolegal and religious issues and may thus improve end-of-life care.

Mass brain tissue lost after decompressive craniectomy: A case report

BACKGROUND

The brain is the most important organ to maintain life. However, the amount of brain tissue required for maintaining life in humans has not been previously reported.

CASE SUMMARY

A 33-year-old woman fell from the third floor three months before admission to our department. She received a decompressive craniectomy soon after injury. After the operation, operative incision disunion occurred due to the high pressure. Brain tissue flowed from the incision, and intracranial infection occurred. She fell into deep coma and was sent to our hospital. Her right temporal surgical incision was not healed and had a cranial defect of 10 cm × 10 cm. Her intracranial cavity was observed from the skull defect, and the brain tissue was largely lost. In addition, no brain tissue was observed by visual inspection. Cranial computed tomography showed that only a small amount of brain tissue density shadow was compressed in the cerebellum and brainstem. Four days after hospitalization in our hospital, her parents transferred her to a hospital near her hometown. The patient died six days after discharge from our hospital.

CONCLUSION

This rare case provides some proof of the importance of the brainstem in the maintenance of cardiac rhythm and vascular tension. Neurosurgeons should carefully protect brainstem neurons during operations. Clinicians can maintain the cardiac rhythm of patients who lose their major brain tissue with modern technology, but the family of the patients should be aware of death and end-life care.

Change in perception of the quality of death in the intensive care unit by healthcare workers associated with the implementation of the "well-dying law"

Purpose

The importance of dying with dignity in the intensive care unit (ICU) has been emphasized. The South Korean government implemented the “well-dying law” in 2018, which enables patients to refuse futile life-sustaining treatment (LST) after being determined as terminally ill. We aimed to study whether the well-dying law is associated with a significant change in the quality of death in the ICU.

Methods

The Quality of Dying and Death (QODD) questionnaires were prospectively collected from the doctors and nurses of deceased patients of four South Korean medical ICUs after the law was passed (January 2019 to May 2020). Results were compared with those of our previous study, which used the same metric before the law was passed (June 2016 to May 2017). We compared baseline characteristics of the deceased patients, enrolled staff, QODD scores, and staff opinions about withdrawing LST from before to after the law was passed.

Results

After the well-dying law was passed, deceased patients (N = 252) were slightly older (68.6 vs. 66.6, p = 0.03) and fewer patients were admitted to the ICU for post-resuscitation care (10.3% vs. 20%, p = 0.003). The mean total QODD score significantly increased after the law was passed (36.9 vs. 31.3, p = 0.001). The law had a positive independent association with the increased QODD score in a multiple regression analysis.

Conclusion

Our study is the first to show that implementing the well-dying law is associated with quality of death in the ICU, although the quality of death in South Korea remains relatively low and should be further improved.

Prevalence and related factors of do-not-resuscitate orders among in-hospital cardiac arrest patients

PURPOSE

Studies concerning do-not-resuscitate (DNR) orders in mainland China are rather scarce. We explored the prevalence and related factors of DNR orders among in-hospital cardiac arrest (IHCA) patients at a general tertiary hospital in mainland China.

MATERIALS AND METHODS

We identified all IHCA patients hospital-wide between July 2019 and September 2020. Data regarding DNR status were collected from medical records. We investigated the frequency of DNR orders and explored the determinant factors of DNR establishment using logistic regression.

RESULTS

A total of 1154 IHCA patients were included, 535 (46.4%) of whom established DNR orders. The following variables were independently associated with a higher DNR rate: female (OR 1.491; 95% CI 1.130-1.965), older age (OR 1.016; 95% CI 1.008-1.024), being a local resident (OR 1.790; 95% CI 1.344-2.383), pulmonary infection (OR 1.398; 95% CI 1052-1.859), respiratory insufficiency (OR 1.356; 95% CI 1.009-1.823), shock (OR 1.735; 95% CI 1.301-2.313), acute stroke (OR 1.821; 95% CI 1.235-2.686),neurological dysfunction (OR 1.527; 95% CI 1.149-2.028) and cancer (OR 3.316; 95% CI 2.461-4.468). Counterintuitively, patients with new-onset coronary artery disease (OR 0.592; 95% CI 0.419-0.837) were less likely to create DNR orders.

CONCLUSION

In mainland China, the DNR order signing rate is low, and the establishment of a DNR order is associated with demographics and comorbidity characteristics.

The story of critical care in Asia: a narrative review

Background

Asia has more critically ill people than any other part of our planet. The aim of this article is to review the development of critical care as a specialty, critical care societies and education and research, the epidemiology of critical illness as well as epidemics and pandemics, accessibility and cost and quality of critical care, culture and end-of-life care, and future directions for critical care in Asia.

Main body

Although the first Asian intensive care units (ICUs) surfaced in the 1960s and the 1970s and specialisation started in the 1990s, multiple challenges still exist, including the lack of intensivists, critical care nurses, and respiratory therapists in many countries. This is aggravated by the brain drain of skilled ICU staff to high-income countries. Critical care societies have been integral to the development of the discipline and have increasingly contributed to critical care education, although critical care research is only just starting to take off through collaboration across groups. Sepsis, increasingly aggravated by multidrug resistance, contributes to a significant burden of critical illness, while epidemics and pandemics continue to haunt the continent intermittently. In particular, the coronavirus disease 2019 (COVID-19) has highlighted the central role of critical care in pandemic response. Accessibility to critical care is affected by lack of ICU beds and high costs, and quality of critical care is affected by limited capability for investigations and treatment in low- and middle-income countries. Meanwhile, there are clear cultural differences across countries, with considerable variations in end-of-life care. Demand for critical care will rise across the continent due to ageing populations and rising comorbidity burdens. Even as countries respond by increasing critical care capacity, the critical care community must continue to focus on training for ICU healthcare workers, processes anchored on evidence-based medicine, technology guided by feasibility and impact, research applicable to Asian and local settings, and rallying of governments for support for the specialty.

Conclusions

Critical care in Asia has progressed through the years, but multiple challenges remain. These challenges should be addressed through a collaborative approach across disciplines, ICUs, hospitals, societies, governments, and countries.

Variations in end-of-life practices in intensive care units worldwide (Ethicus-2): a prospective observational study

BACKGROUND

End-of-life practices vary among intensive care units (ICUs) worldwide. Differences can result in variable use of disproportionate or non-beneficial life-sustaining interventions across diverse world regions. This study investigated global disparities in end-of-life practices.

METHODS

In this prospective, multinational, observational study, consecutive adult ICU patients who died or had a limitation of life-sustaining treatment (withholding or withdrawing life-sustaining therapy and active shortening of the dying process) during a 6-month period between Sept 1, 2015, and Sept 30, 2016, were recruited from 199 ICUs in 36 countries. The primary outcome was the end-of-life practice as defined by the end-of-life categories: withholding or withdrawing life-sustaining therapy, active shortening of the dying process, or failed cardiopulmonary resuscitation (CPR). Patients with brain death were included in a separate predefined end-of-life category. Data collection included patient characteristics, diagnoses, end-of-life decisions and their timing related to admission and discharge, or death, with comparisons across different regions. Patients were studied until death or 2 months from the first limitation decision.

FINDINGS

Of 87 951 patients admitted to ICU, 12 850 (14·6%) were included in the study population. The number of patients categorised into each of the different end-of-life categories were significantly different for each region (p<0·001). Limitation of life-sustaining treatment occurred in 10 401 patients (11·8% of 87 951 ICU admissions and 80·9% of 12 850 in the study population). The most common limitation was withholding life-sustaining treatment (5661 [44·1%]), followed by withdrawing life-sustaining treatment (4680 [36·4%]). More treatment withdrawing was observed in Northern Europe (1217 [52·8%] of 2305) and Australia/New Zealand (247 [45·7%] of 541) than in Latin America (33 [5·8%] of 571) and Africa (21 [13·0%] of 162). Shortening of the dying process was uncommon across all regions (60 [0·5%]). One in five patients with treatment limitations survived hospitalisation. Death due to failed CPR occurred in 1799 (14%) of the study population, and brain death occurred in 650 (5·1%). Failure of CPR occurred less frequently in Northern Europe (85 [3·7%] of 2305), Australia/New Zealand (23 [4·3%] of 541), and North America (78 [8·5%] of 918) than in Africa (106 [65·4%] of 162), Latin America (160 [28·0%] of 571), and Southern Europe (590 [22·5%] of 2622). Factors associated with treatment limitations were region, age, and diagnoses (acute and chronic), and country end-of-life legislation.

INTERPRETATION

Limitation of life-sustaining therapies is common worldwide with regional variability. Withholding treatment is more common than withdrawing treatment. Variations in type, frequency, and timing of end-of-life decisions were observed. Recognising regional differences and the reasons behind these differences might help improve end-of-life care worldwide.

FUNDING

None.

Factors facilitating positive outcomes in community-based end-of-life care: A cross-sectional qualitative study of patients and family caregivers

BACKGROUND

Delivery of community-based end-of-life care for patients and family members has been recognized as an important public health care approach. Despite differences in different healthcare settings and the significance of a person-centered approach, little research has investigated facilitators of community-based end-of-life care from the perspective of service recipients. In particular, there has been limited exploration of strategies to ensure positive outcomes at an operational level.

AIM

To explore factors facilitating positive end-of-life care provision in community-based settings and how these are achieved in practice, from the perspectives of patients and family caregivers.

DESIGN

A qualitative cross-sectional descriptive study was undertaken through semi-structured interviews with patients and family caregivers subjected to thematic analysis.

SETTING/PARTICIPANTS

Ten patients and 16 family caregivers were recruited from an end-of-life community care program provided by four non-governmental organizations in Hong Kong.

RESULTS

Seven core themes were identified: positive emotions about the relationship, positive appraisals of the relationship, care through inquiring about recipients' circumstances, instrumentality of care (i.e. information, coaching on care, practical help, psychological support, multiple activities), comprehensiveness of care (i.e. diversity, post-death care, family-level wellbeing), structure of care (i.e. timely follow-up, well-developed system), and qualities of workers.

CONCLUSIONS

Improvement in service quality might be achieved through alternating the perceptions or emotional reactions of care recipients toward care providers and increased use of sensitive inquiry. Comprehensive care and positive outcomes might be facilitated by addressing the dualities of care by providing diverse choices in pre-death and post-death care.

Family Members' Knowledge and Attitude Toward Life-Sustaining Treatment Decisions for Patients in the Intensive Care Unit

The decision to withhold or withdraw life-sustaining treatment (LST) lies sometimes in the hands of intensive care unit patients' families. Since 2018, family members of dying patients in South Korea have had the legal right to make decisions for the patients. This study aimed to examine knowledge and attitude toward LST among the family members of patients under intensive care since the foundation of the new legislation. Their perceptions of the roles of nurses were also explored. In this cross-sectional study, 89 participants completed survey questionnaires on demographic characteristics, relationship to patient, reason for admission, length of stay, awareness of the new legislation, knowledge and attitude toward LST, and perception of the role of nurses. The results indicated that knowledge was significantly associated with attitude and was, in fact, the only predictor of attitude toward LST (P = .021). Explaining the disease and prognosis in detail and relieving patients of their physical pain were the roles of nurses most valued by family members. The findings suggest that it is crucial for nurses to support family members and provide information about critical changes and medical options for collaborative decision making according to the patients' wishes during the dying process.

The differences in nurses' willingness to discuss palliative care with patients and their family members

BACKGROUND

This study aimed to evaluate the differences in nurses' willingness to discuss palliative care with terminally ill patients and their family members.

METHODS

The participants were randomly recruited from registered staff nurses ≥20 years of age who were responsible for clinical inpatient care in a tertiary hospital in northern Taiwan. A semi-structured questionnaire was administered to evaluate nurses' experiences of discussing do-not-resuscitate (DNR) decisions and their willingness to discuss palliative care with terminal patients and their family members. The differences in nurses' experiences regarding DNR and willingness to discuss palliative care with terminally ill patients and their family members were compared using the Chi-square test. Logistic regressions were used to analyze factors associated with nurses' willingness to discuss palliative care with patients and their families.

RESULTS

More participants had experienced initiating discussions about DNR with patients' families than with patients (72.2% vs 61.9%, p < 0.001). Unadjusted logistic regression analysis showed that the experiences of actively initiating DNR discussions with patients were a significant factor associated with palliative care discussion with patients (odds ratio [OR] = 2.91, 95% confidence interval [CI]: 1.09-7.79). On the other hand, the experiences of actively initiating DNR discussions with patients and with patients' families were significant factors associated with palliative care discussion with patients' families (OR = 3.84, 95% CI: 1.22-12.06 and OR = 3.60, 95% CI: 1.19-10.90, respectively). After adjusting for covariates, no significant factors were found to be independently associated with nurses' willingness to discuss palliative care with patients and their family members.

CONCLUSION

There are significant differences in nurses' willingness to discuss palliative care with patients and their family members. Further research is needed to evaluate factors associated with nurses' willingness to discuss palliative care with patients and their families to facilitate these discussions and protect patients' autonomy.

Reframing the meaning of life and professional values: A theoretical framework of facilitating professional care for terminally ill patients

Professional values reflect nurses' understanding of how to deliver professional care, which might influence nurses' attitudes and caring behaviors during end-of-life care. However, limited research has been conducted to explore nurses' experiences of professional development during end-of-life care, and theoretical explanations are scarce about how nurses enact their professional values during the caring process. This study explored the social process of professional values involved in end-of-life care in the Chinese cultural context by adopting a constructivist grounded theory approach. Twenty semi-structured in-depth interviews with 15 nurses from three hospitals in southeastern China were conducted. A theoretical framework emerged when focusing on the social process of "reframing the meaning of life and professional values" to facilitate professional care for terminally ill patients. Three main categories were sequentially identified as "recognizing the dilemmas when caring for terminally ill patients," "applying strategies to deal with values conflict," and "reconstructing values." This theoretical framework may be applied as a practical framework for equipping nurses with effective strategies to cultivate professional values, including the provision of adequate end-of-life knowledge, and a supportive workplace environment.

The impact of caring for dying patients in intensive care units on a physician's personhood: a systematic scoping review

BACKGROUND

Supporting physicians in Intensive Care Units (ICU)s as they face dying patients at unprecedented levels due to the COVID-19 pandemic is critical. Amidst a dearth of such data and guided by evidence that nurses in ICUs experience personal, professional and existential issues in similar conditions, a systematic scoping review (SSR) is proposed to evaluate prevailing accounts of physicians facing dying patients in ICUs through the lens of Personhood. Such data would enhance understanding and guide the provision of better support for ICU physicians.

METHODS

An SSR adopts the Systematic Evidenced Based Approach (SEBA) to map prevailing accounts of caring for dying patients in ICUs. To enhance the transparency and reproducibility of this process, concurrent and independent use of tabulated summaries, thematic analysis and directed content analysis (Split Approach) is adopted.

RESULTS

Eight thousand three hundred fifty-eight abstracts were reviewed from four databases, 474 full-text articles were evaluated, 58 articles were included, and the Split Approach revealed six categories/themes centered around the Innate, Individual, Relational and Societal Rings of Personhood, conflicts in providing end of life care and coping mechanisms employed.

CONCLUSION

This SSR suggests that caring for dying patients in ICU impacts how physicians view their personhood. To resolve conflicts within individual concepts of personhood, physicians use prioritization, reframing and rely on accessible, personalized support from colleagues to steer coping strategies. An adapted form of the Ring Theory of Personhood is proposed to direct timely personalized, appropriate and holistic support.

Perceptions of optimal end-of-life care in hospitals: A cross-sectional study of nurses in three locations

AIM

To examine whether nurses' location of employment, demographics, or training influences their perceptions of what constitutes optimal care for dying patients in hospital.

DESIGN

Questionnaire-based, cross-sectional study.

METHODS

Between December 2016-June 2018, 582 registered or enrolled nurses from Australia (N = 153), South Korea (N = 241), and Hong Kong (N = 188) employed in a variety of hospital care units rated the extent to which they agreed with 29 indicators of optimal end-of-life care across four domains: patient, family, healthcare team, and healthcare system. Latent class analysis identified classes of respondents with similar responses.

RESULTS

Top five indicators rated by participants included: 'physical symptoms managed well'; 'private rooms and unlimited visiting hours'; 'spend as much time with the patient as families wish'; 'end-of-life care documents stored well and easily accessed' and 'families know and follow patient's wishes'. Four latent classes were generated: 'Whole system/holistic' (Class 1); 'Patient/provider-dominated' (Class 2); 'Family-dominated' (Class 3) and 'System-dominated' (Class 4). Class 1 had the highest proportion of nurses responding positively for all indicators. Location was an important correlate of perceptions, even after controlling for individual characteristics.

CONCLUSION

Nurses' perceptions of optimal end-of-life care are associated with location, but perhaps not in the direction that stereotypes would suggest. Findings highlight the importance of developing and implementing location-specific approaches to optimize end-of-life care in hospitals.

IMPACT

The findings may be useful to guide education and policy initiatives in Asian and Western countries that stress that end-of-life care is more than symptom management. Indicators can be used to collect data that help quantify differences between optimal care and the care actually being delivered, thereby determining where improvements might be made.

Timing of do-not-resuscitate orders and health care utilization near the end of life in cancer patients: a retrospective cohort study

PURPOSE

The objectives are to explore the prevalence of DNR orders, the factors influencing them, and the association between DNR signing and health care utilization among advanced cancer patients.

METHODS

This was a retrospective cohort study. Data from cancer decedents in three hospitals in China from January 2016 to December 2017 during their last hospitalization before death were obtained from the electronic medical records system.

RESULTS

In total, 427 cancer patients were included; 59.0% had a DNR order. Patients who had solid tumors, lived in urban areas, had more than one comorbidity, and had more than five symptoms were more likely to have DNR orders. The cut-off of the timing of obtaining a DNR order was 3 days, as determined by the median number of days from the signing of a DNR order to patient death. Patients with early DNR orders (more than 3 days before death) were less likely to be transferred to the intensive care unit and undergo cardiopulmonary resuscitation, tracheal intubation, and ventilation, while they were more likely to be given morphine and psychological support compared with those with late (within 3 days before death) and no orders.

CONCLUSIONS

Advanced cancer patients with solid tumors living in urban areas with more symptoms and comorbidities are relatively more likely to have DNR orders. Early DNR orders are associated with less aggressive procedures and more comfort measures. However, these orders are always signed late. Future studies are needed to better understand the timing of DNR orders.

Ethics of life-sustaining treatment in locked-in syndrome: A Chinese survey

BACKGROUND

Locked-in syndrome (LIS) characterizes individuals who have experienced pontine lesions, who have limited motor output but with preserved cognitive abilities. Despite their severe physical impairment, individuals with LIS self-profess a higher quality of life than generally expected. Such third-person expectations about LIS are shaped by personal and cultural factors in western countries.

OBJECTIVE

We sought to investigate whether such opinions are further influenced by the cultural background in East Asia. We surveyed attitudes about the ethics of life-sustaining treatment in LIS in a cohort of medical and non-medical Chinese participants.

RESULTS

The final study sample included 1545 respondents: medical professionals (n=597, 39%), neurologists (n=303, 20%), legal professionals (n=276, 18%) and other professionals (n=369, 24%), including 180 family members of individuals with LIS. Most of the participants (70%), especially neurologists, thought that life-sustaining treatment could not be stopped in individuals with LIS. It might be unnecessary to withdraw life-sustaining treatment, because the condition involved is not terminal and irreversible, and physical treatment can be beneficial for the patient. A significant proportion (59%) of respondents would like to be kept alive if they were in that condition; however, older people thought the opposite. Families experience the stress of caring for individuals with LIS. The mean (SD) quality of life score for relatives was 0.73 (2.889) (on a -5, +5 scale), which was significantly lower than that of non-relatives, 1.75 (1.969) (P<0.001).

CONCLUSIONS

Differences in opinions about end of life in LIS are affected by personal characteristics. The current survey did not identify a dissociation between personal preferences and general opinions, potentially because of a social uniformity in China where individualism is less pronounced. Future open-ended surveys could identify specific needs of caregivers so that strategic interventions to reduce ethical debasement are designed.

The quality of dying and death for patients in intensive care units: a single center pilot study

BACKGROUND

To identify the necessary care for dying patients in intensive care units (ICUs), we designed a retrospective study to evaluate the quality of dying and death (QODD) experienced by the surrogates of patients with medical illness who died in the ICU of a tertiary referral hospital.

METHODS

To achieve our objective, the authors compared the QODD scores as appraised by the relatives of patients who died of cancer under hospice care with those who died in the ICU. For this study, a Korean version of the QODD questionnaire was developed, and individual interviews were also conducted.

RESULTS

Sixteen people from the intensive care group and 23 people from the hospice care group participated in the survey and completed the questionnaire. The family members of patients who died in the ICU declined participation at a high rate (50%), with the primary reason being to avoid bringing back painful memories (14 people, 87.5%). The relatives of the intensive care group obtained an average total score on the 17-item QODD questionnaire, which was significantly lower than that of the relatives of the hospice group (48.7±15.5 vs. 60.3±14.8, P=0.03).

CONCLUSIONS

This work implies that there are unmet needs for the care of dying patients and for the QODD in tertiary hospital ICUs. This result suggests that shared decision making for advance care planning should be encouraged and that education on caring for dying patients should be provided to healthcare professionals to improve the QODD in Korean ICUs.

Post-intensive care syndrome: its pathophysiology, prevention, and future directions

Expanding elderly populations are a major social challenge in advanced countries worldwide and have led to a rapid increase in the number of elderly patients in intensive care units (ICUs). Innovative advances in medical technology have enabled lifesaving of patients in ICUs, but there remain various problems to improve their long-term prognoses. Post-intensive care syndrome (PICS) refers to physical, cognition, and mental impairments that occur during ICU stay, after ICU discharge or hospital discharge, as well as the long-term prognosis of ICU patients. Its concept also applies to pediatric patients (PICS-p) and the mental status of their family (PICS-F). Intensive care unit-acquired weakness, a syndrome characterized by acute symmetrical limb muscle weakness after ICU admission, belongs to physical impairments in three domains of PICS. Prevention of PICS requires performance of the ABCDEFGH bundle, which incorporates the prevention of delirium, early rehabilitation, family intervention, and follow-up from the time of ICU admission to the time of discharge. Diary, nutrition, nursing care, and environmental management for healing are also important in the prevention of PICS. This review outlines the pathophysiology, prevention, and future directions of PICS.

Perspectives on End-of-Life Treatment among Patients with COPD: A Multicenter, Cross-sectional Study in Japan

Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality. Since patients with severe COPD may experience exacerbations and eventually face mortality, advanced care planning (ACP) has been increasingly emphasized in the recent COPD guidelines. We conducted a multicenter, cross-sectional study to survey the current perspectives of Japanese COPD patients toward ACP. "High-risk" COPD patients and their attending physicians were consecutively recruited. The patients' family configurations, understanding of COPD pathophysiology, current end-of-life care communication with physicians and family members, and preferences for invasive life-sustaining treatments including mechanical ventilation (MV) and cardiopulmonary resuscitation (CPR) were evaluated using a custom-made, structured, self-administered questionnaire. Attending physicians were also interviewed, and we evaluated the patient-physician agreement. Among the 224 eligible "high-risk" patients, 162 participated. Half of the physicians (54.4%) thought they had communicated detailed information; however, only 19.4% of the COPD patients thought the physicians did so (κ score = 0.16). Less than 10% of patients wanted to receive invasive treatment (MV, 6.3% and CPR, 9.4%); interestingly, more than half marked their decision as "refer to the physician" (MV 42.5% and CPR 44.4%) or "refer to family" (MV, 13.8% and CPR, 14.4%). Patients with less knowledge of COPD were less likely to indicate that they had already made a decision. Although ACP is necessary to cope with severe COPD, Japanese "high-risk" COPD patients were unable to make a decision on their preferences for invasive treatments. Lack of disease knowledge and communication gaps between patients and physicians should be addressed as part of these patients' care.
