Physicians' psychosocial barriers to different modes of withdrawal of life support in critical care: A qualitative study in Japan

Navigating tensions when life-sustaining treatment is withdrawn: A thematic synthesis of nurses' and physicians' experiences

AIM

To synthesise nurses' and physicians' experiences with withdrawing life-sustaining treatment in an intensive care unit.

DESIGN

The chosen methodology is thematic synthesis. The Preferred Reporting Items for Systematic Review and Meta-Analyses and Enhancing Transparency are used in Reporting the Synthesis of Qualitative Research Statement.

METHODS AND DATA SOURCES

A systematic search is conducted in APA PsycINFO, CINAHL Plus, EMBASE, PubMed and Web of Science following the inclusion and exclusion criteria in April 2023. Two reviewers independently screened and extracted the qualitative data. Subsequently, data analysis was conducted using thematic analysis of qualitative research. This study was not registered with any review registry due to the irrelevance of the data to health-related outcomes.

RESULTS

From the 16 articles, 267 quotes were extracted and analysed. The findings of the study revealed five analytical themes: (1) tensions between interdependent collaboration and hierarchical roles; (2) tensions between dignified dying or therapeutic perspectives; (3) family members' reflections of patient's wishes; (4) tensions in family members' positions; and (5) double-sidedness of distress.

CONCLUSION

This study contributes to nursing knowledge by providing a more nuanced understanding of this complex phenomenon of withdrawing life-sustaining treatment. The findings of this study have revealed significant variations globally in the practices surrounding the withdrawal of life-sustaining treatment in intensive care units, emphasising the need for further research to inform clinical practices that cater to diverse contexts.

REPORTING METHOD

Enhancing Transparency are used in Reporting the Synthesis of Qualitative Research Statement (ENTREQ statement).

PATIENT OR PUBLIC CONTRIBUTION

Since this study reported a potential collision between the patient's dignified dying and the family member's perceptions and interests, the family member's wishes should be carefully distinguished from the patient's quality of end of life in practice.

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.

Terminal withdrawal of mechanical ventilation in adult intensive care units: A systematic review and narrative synthesis of perceptions, experiences and practices

BACKGROUND

During the terminal withdrawal of life-sustaining measures for intensive care patients, the removal of respiratory support remains an ambiguous practice. Globally, perceptions and experiences of best practice vary due to the limited evidence in this area.

AIM

To identify, appraise and synthesise the latest evidence around terminal withdrawal of mechanical ventilation in adult intensive care units specific to perceptions, experiences and practices.

DESIGN

Mixed methods systematic review and narrative synthesis. A review protocol was registered on PROSPERO (CRD42018086495).

DATA SOURCES

Four electronic databases were systematically searched (Medline, Embase, CENTRAL and CINAHL). Obtained articles published between January 2008 and January 2020 were screened for eligibility. All included papers were appraised using relevant appraisal tools.

RESULTS

Twenty-five papers were included in the review. Findings from the included papers were synthesised into four themes: 'clinicians' perceptions and practices'; 'time to death and predictors'; 'analgesia and sedation practices'; 'physiological and psychological impact'.

CONCLUSIONS

Perceptions, experiences and practices of terminal withdrawal of mechanical ventilation vary significantly across the globe. Current knowledge highlights that the time to death after withdrawal of mechanical ventilation is very short. Predictors for shorter duration could be considered by clinicians and guide the choice of pharmacological interventions to address distressing symptoms that patients may experience. Clinicians ought to prepare patients, families and relatives for the withdrawal process and the expected progression and provide them with immediate and long-term support following withdrawal. Further research is needed to improve current evidence and better inform practice guidelines.

Outcomes related to 10-min Apgar scores of zero in Japan

OBJECTIVE

Apgar scores of zero at 10 min strongly predict mortality and morbidity in infants. However, recent data reported improved outcomes among infants with Apgar scores of zero at 10 min. We aimed to review the mortality rate and neurodevelopmental outcomes of infants with Apgar scores of zero at 10 min in Japan.

DESIGN

Observational study.

PATIENTS

Twenty-eight of 768 infants registered in the Baby Cooling Registry of Japan between 2012 and 2016, at >34 weeks' gestation, with Apgar scores of zero at 10 min who were treated with therapeutic hypothermia.

INTERVENTIONS

We investigated the time of first heartbeat detection in infants with favourable outcomes and who had neurodevelopmental impairments or died.

MAIN OUTCOME MEASURES

Clinical characteristics, mortality rate and neurodevelopmental outcomes at 18-22 months of age were evaluated.

RESULTS

Nine (32%) of the 28 infants died before 18 months of age; 16 (57%) survived, but with severe disabilities and 3 (11%) survived without moderate-to-severe disabilities. At 20 min after birth, 14 of 27 infants (52%) did not have a first heartbeat, 13 of them died or had severe disabilities and one infant, who had the first heartbeat at 20 min, survived without disability.

CONCLUSION

Our study adds to the recent evidence that neurodevelopmental outcomes among infants with Apgar scores of zero at 10 min may not be uniformly poor. However, in our study, all infants with their first heartbeat after 20 min of age died or had severe disabilities.

Worldwide end-of-life practice for patients in ICUs

PURPOSE OF REVIEW

Published data and practice recommendations on end-of-life (EOL) generally reflect Western practice frameworks. Understanding worldwide practices is important because improving economic conditions are promoting rapid expansion of intensive care services in many previously disadvantaged regions, and increasing migration has promoted a new cultural diversity previously predominantly unicultural societies. This review explores current knowledge of similarities and differences in EOL practice between regions and possible causes and implications of these differences.

RECENT FINDINGS

Recent observational and survey data shows a marked variability in the practice of withholding and withdrawing life sustaining therapy worldwide. Some evidence supports the view that culture, religion, and socioeconomic factors influence EOL practice, and individually or together account for differences observed. There are also likely to be commonly desired values and expectations for EOL practice, and recent attempts at establishing where worldwide consensus may lie have improved our understanding of shared values and practices.

SUMMARY

Awareness of differences, understanding their likely complex causes, and using this knowledge to inform individualized care at EOL is likely to improve the quality of care for patients. Further research should clarify the causes of EOL practice variability, monitor trends, and objectively evaluate the quality of EOL practice worldwide.

Terminal weaning or immediate extubation for withdrawing mechanical ventilation in critically ill patients (the ARREVE observational study)

PURPOSE

The relative merits of immediate extubation versus terminal weaning for mechanical ventilation withdrawal are controversial, particularly regarding the experience of patients and relatives.

METHODS

This prospective observational multicentre study (ARREVE) was done in 43 French ICUs to compare terminal weaning and immediate extubation, as chosen by the ICU team. Terminal weaning was a gradual decrease in the amount of ventilatory assistance and immediate extubation was extubation without any previous decrease in ventilatory assistance. The primary outcome was posttraumatic stress symptoms (Impact of Event Scale Revised, IES-R) in relatives 3 months after the death. Secondary outcomes were complicated grief, anxiety, and depression symptoms in relatives; comfort of patients during the dying process; and job strain in staff.

RESULTS

We enrolled 212 (85.5%) relatives of 248 patients with terminal weaning and 190 relatives (90.5%) of 210 patients with immediate extubation. Immediate extubation was associated with airway obstruction and a higher mean Behavioural Pain Scale score compared to terminal weaning. In relatives, IES-R scores after 3 months were not significantly different between groups (31.9 ± 18.1 versus 30.5 ± 16.2, respectively; adjusted difference, -1.9; 95% confidence interval, -5.9 to 2.1; p = 0.36); neither were there any differences in complicated grief, anxiety, or depression scores. Assistant nurses had lower job strain scores in the immediate extubation group.

CONCLUSIONS

Compared to terminal weaning, immediate extubation was not associated with differences in psychological welfare of relatives when each method constituted standard practice in the ICU where it was applied. Patients had more airway obstruction and gasps with immediate extubation.

US Physicians' Opinions about Distinctions between Withdrawing and Withholding Life-Sustaining Treatment

Decisions to withhold or withdraw life-sustaining treatment (LST) precede the majority of ICU deaths. Although professional guidelines generally treat the two as ethically equivalent, evidence suggests withdrawing LST is often more psychologically difficult than withholding it. The aim of the experiment was to investigate whether physicians are more supportive of withholding LST than withdrawing it and to assess how physicians' opinions are shaped by their religious characteristics, specialty, and experience caring for dying patients. In 2010, a survey was mailed to 2016 practicing US physicians. Physicians were asked whether physicians should always comply with a competent patient's request to withdraw LST, whether withdrawing LST is more psychologically difficult than withholding it, and whether withdrawing LST is typically more ethically problematic than withholding it. Of 1880 eligible physicians, 1156 responded to the survey (62%); 93% agreed that physicians should always comply with a competent patient's request to withdraw LST. More than half of the physicians reported that they find withdrawing LST more psychologically difficult than withholding it (61%), and that withdrawing LST is typically more ethically problematic (59%). Physician religiosity was associated with finding withdrawal more ethically problematic, but not with finding it more psychologically difficult. Physicians working in an end-of-life specialty and physicians with more experience caring for dying patients were less likely to endorse either a psychological or an ethical distinction between withdrawing and withholding LST. Most US physicians find withdrawing LST not only more psychologically difficult, but also more ethically problematic than withholding such treatment. Physicians' opinions are to some extent shaped by their religious characteristics, specialty, and levels of experience caring for dying patients.

Guidelines for the withdrawal of life-sustaining measures

BACKGROUND

Withdrawal of life-sustaining measures is a common event in the intensive care unit yet it involves a complex balance of medical, legal and ethical considerations. Very few healthcare providers have been specifically trained to withdraw life-sustaining measures, and no comprehensive guidelines exist to help ensure clinicians deliver the highest quality of care to patients and families. Hence, we sought to develop guidelines for the process of withdrawing life-sustaining measures in the clinical setting.

METHODS

We convened an interdisciplinary group of ICU care providers from the Canadian Critical Care Society and the Canadian Association of Critical Care Nurses, and used a modified Delphi process to answer key clinical and ethical questions identified in the literature.

RESULTS

A total of 39 experienced clinicians completed the initial workshop, and 36 were involved in the subsequent Delphi rounds. The group developed a series of guidelines to address (1) preparing for withdrawal of life-sustaining measures; (2) assessment of distress; (3) pharmaceutical management of distress; and (4) discontinuation of life-sustaining measures and monitoring. The group achieved consensus on all aspects of the guidelines after the third Delphi round.

CONCLUSION

We present these guidelines to help physicians provide high-quality end of life (EOL) care in the ICU. Future studies should address their effectiveness from both critical care team and family perspectives.

Nondialytic therapy for elderly patients in a critical care setting

It is frequently necessary to admit critically ill elderly patients to intensive care units (ICUs) due to their physiological impairments and co-morbidities. Several life-sustaining therapies such as mechanical ventilation are performed as necessary treatment in these ICUs. Sometimes renal replacement therapy (i.e. dialysis) is considered for elderly patients with complicating serious renal insufficiency. However, although the necessity for dialysis is recognized, some elderly patients may not benefit from this care because of their limited life expectancy. Until recently, life-sustaining support for critically ill elderly patients in Japan has been used routinely, regardless of the medical futility. The issue of providing better end-of-life care for elderly patients even in the ICU is now being raised frequently. We therefore wish to highlight the issue of end-of-life care and decision-making in the ICU, focusing on nondialytic therapy (NDT). The aim of this article was to assess whether NDT is an acceptable optional care for critically ill elderly patients with serious kidney diseases, even in the ICU. We hope our experiences may be helpful to physicians with an interest in decision-making and end-of-life care.

A comparative survey on potentially futile treatments between Japanese nurses and laypeople

In the issue of futile treatments, patients and healthcare professionals tend to disagree. We conducted an Internet questionnaire survey and explored the Japanese nurses' attitude toward this topic, comparing with that of laypeople. In total, 522 nurses and 1134 laypeople completed the questionnaire. Nurse respondents were significantly less in favor of providing potentially futile treatments in hypothetical vignettes and stressed quality of life of the patient for judging the futility of a certain treatment. Of them, 85.4% reported having experienced providing such treatments. Reasons for providing them included factors related to not only patients but also healthcare teams. Our results indicate that attitudes among Japanese nurses toward the issue of futile treatments are different from patients and that their actual practice is influenced by several situational factors.
