Decision tools for life support: a review and policy analysis

Moral equivalence theory in neonatology

This article explores the ethical concept of "the equivalence thesis" (ET), or the idea that withdrawing and withholding life sustaining treatments are morally equivalent practices, within neonatology. We review the historical origins, theory, and clinical rationale behind ET, and provide an analysis of how ET relates to literature that describes neonatal mode of death and healthcare professional and parent attitudes towards end-of-life care. While ET may serve as an ethical tool to optimize resource allocation in theory, its clinical utility is limited given the complexity of end-of-life care decisions.

Pediatric Resident Experience Caring for Children at the End of Life in a Children's Hospital

OBJECTIVE

Pediatric residents are expected to be competent in end-of-life (EOL) care. We aimed to quantify pediatric resident exposure to patient deaths, and the context of these exposures.

METHODS

Retrospective chart review of all deceased patients at one children's hospital over 3 years collected patient demographics, time, and location of death. Mode of death was determined after chart review. Each death was cross-referenced with pediatric resident call schedules to determine residents involved within 48 hours of death. Descriptive statistics are presented.

RESULTS

Of 579 patients who died during the study period, 46% had resident involvement. Most deaths occurred in the NICU (30% of all deaths); however, resident exposure to EOL care most commonly occurred in the PICU (52% of resident exposures) and were after withdrawals of life-sustaining therapy (41%), followed by nonescalation (31%) and failed resuscitation (15%). During their postgraduate year (PGY)-1, <1% of residents encountered a patient death. During PGY-2 and PGY-3, 96% and 78%, respectively, of residents encountered at least 1 death. During PGY-2, residents encountered a mean of 3.5 patient deaths (range 0-12); during PGY-3, residents encountered a mean of 1.4 deaths (range 0-5). Residents observed for their full 3-year residency encountered a mean of 5.6 deaths (range 2-10).

CONCLUSIONS

Pediatric residents have limited but variable exposure to EOL care, with most exposures in the ICU after withdrawal of life-sustaining technology. Educators should consider how to optimize EOL education with limited clinical exposure, and design resident support and education with these variable exposures in mind.

Withholding and Withdrawal of Treatments: Differences in Perceptions between Intensivists, Oncologists, and Prosecutors in Brazil

Background: Legal concerns have been implicated in the occurrence of variability in decisions of limitations of medical treatment (LOMT) before death. Objective: We aimed to assess differences in perceptions between physicians and prosecutors toward LOMT. Measurements: We sent a survey to intensivists, oncologists, and prosecutors from Brazil, from February 2018 to May 2018. Respondents rated the degree of agreement with withholding or withdrawal of therapies in four different vignettes portraying a patient with terminal lung cancer. We measured the difference in agreement between respondents. Results: There were 748 respondents, with 522 (69.8%) intensivists, 106 (14.2%) oncologists, and 120 (16%) prosecutors. Most respondents agreed with withhold of chemotherapy (95.2%), withhold of mechanical ventilation (MV) (90.2%), and withdrawal of MV (78.4%), but most (75%) disagreed with withdrawal of MV without surrogate's consent. Prosecutors were less likely than intensivists and oncologists to agree with withhold of chemotherapy (95.7% vs. 99.2% vs. 100%, respectively, p < 0.001) and withhold of MV (82.4% vs. 98.3% vs. 97.9%, respectively, p < 0.001), whereas intensivists were more likely to agree with withdrawal of MV than oncologists (87.1% vs. 76.1%, p = 0.002). Moreover, prosecutors were more likely to agree with withholding of active cancer treatment than with withholding of MV [difference (95% confidence interval, CI) = 13.2% (5.2 to 21.6), p = 0.001], whereas physicians were more likely to agree with withholding than with withdrawal of MV [difference (95% CI) = 10.9% (7.8 to 14), p < 0.001]. Conclusions: This study found differences and agreements in perceptions toward LOMT between prosecutors, intensivists, and oncologists, which may inform the discourse aimed at improving end-of-life decisions.

Hemodialysis as a life-sustaining treatment at the end of life

The Act on Decisions on Life-Sustaining Treatment for Patients in Hospice and Palliative Care or at the End of Life came into effect on February 4th, 2018, in South Korea. Based on the Act, all Koreans over the age of 19 years can decide whether to refuse life-sustaining treatments at the end of life via advance directive or physician orders. Hemodialysis is one of the options designated in the Act as a life-sustaining treatment that can be withheld or withdrawn near death. However, hemodialysis has unique features. So, it is not easy to determine the best candidates for withholding/withdrawing hemodialysis at the end of life. Thus, it is necessary to investigate the meaning and implications of hemodialysis at the end of life with ethical consideration of futility and withholding or withdrawal of intervention.

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

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

The Durban World Congress Ethics Round Table Conference Report: I. Differences between withholding and withdrawing life-sustaining treatments

INTRODUCTION

Withholding life-sustaining treatments (WHLST) and withdrawing life-sustaining treatments (WDLST) occur in most intensive care units (ICUs) around the world to varying degrees.

METHODS

Speakers from invited faculty of the World Federation of Societies of Intensive and Critical Care Medicine Congress in 2013 with an interest in ethics were approached to participate in an ethics round table. Participants were asked if they agreed with the statement "There is no moral difference between withholding and withdrawing a mechanical ventilator." Differences between WHLST and WDLST were discussed. Official statements relating to WHLST and WDLST from intensive care societies, professional bodies, and government statements were sourced, documented, and compared.

RESULTS

Sixteen respondents stated that there was no moral difference between withholding or withdrawing a mechanical ventilator, 2 were neutral, and 4 stated that there was a difference. Most ethicists and medical organizations state that there is no moral difference between WHLST and WDLST. A review of guidelines noted that all but 1 of 29 considered WHLST and WDLST as ethically or legally equivalent.

CONCLUSIONS

Most respondents, practicing intensivists, stated that there is no difference between WHLST and WDLST, supporting most ethicists and professional organizations. A minority of physicians still do not accept their equivalency.

Inclusion of ethical issues in dementia guidelines: a thematic text analysis

BACKGROUND

Clinical practice guidelines (CPGs) aim to improve professionalism in health care. However, current CPG development manuals fail to address how to include ethical issues in a systematic and transparent manner. The objective of this study was to assess the representation of ethical issues in general CPGs on dementia care.

METHODS AND FINDINGS

To identify national CPGs on dementia care, five databases of guidelines were searched and national psychiatric associations were contacted in August 2011 and in June 2013. A framework for the assessment of the identified CPGs' ethical content was developed on the basis of a prior systematic review of ethical issues in dementia care. Thematic text analysis and a 4-point rating score were employed to assess how ethical issues were addressed in the identified CPGs. Twelve national CPGs were included. Thirty-one ethical issues in dementia care were identified by the prior systematic review. The proportion of these 31 ethical issues that were explicitly addressed by each CPG ranged from 22% to 77%, with a median of 49.5%. National guidelines differed substantially with respect to (a) which ethical issues were represented, (b) whether ethical recommendations were included, (c) whether justifications or citations were provided to support recommendations, and (d) to what extent the ethical issues were explained.

CONCLUSIONS

Ethical issues were inconsistently addressed in national dementia guidelines, with some guidelines including most and some including few ethical issues. Guidelines should address ethical issues and how to deal with them to help the medical profession understand how to approach care of patients with dementia, and for patients, their relatives, and the general public, all of whom might seek information and advice in national guidelines. There is a need for further research to specify how detailed ethical issues and their respective recommendations can and should be addressed in dementia guidelines.

Content analysis of euthanasia policies of nursing homes in Flanders (Belgium)

OBJECTIVES

To describe the form and content of ethics policies on euthanasia in Flemish nursing homes and to determine the possible influence of religious affiliation on policy content.

METHODS

Content analysis of euthanasia policy documents.

RESULTS

Of the 737 nursing homes we contacted, 612 (83%) completed and returned the questionnaire. Of 92 (15%) nursing homes that reported to have a euthanasia policy, 85 (92%) provided a copy of their policy. Nursing homes applied the euthanasia law with additional palliative procedures and interdisciplinary deliberations. More Catholic nursing homes compared to non-Catholic nursing homes did not permit euthanasia. Policies described several phases of the euthanasia care process as well as involvement of caregivers, patients, and relatives; ethical issues; support for caregivers; reporting; and procedures for handling advance directives.

CONCLUSION

Our study revealed that euthanasia requests from patients are seriously considered in euthanasia policies of nursing homes, with great attention for palliative care and interdisciplinary cooperation.

Survival and predictors of outcome in patients with acute leukemia admitted to the intensive care unit

BACKGROUND

Predictors of outcome and rates of successful discharge have not been defined for patients with acute leukemia admitted to intensive care units (ICUs) in the US.

METHODS

This is a retrospective analysis of 90 patients with acute leukemia (no history of bone marrow transplant) admitted to an ICU from 2001-2004. The primary endpoints were improvement and subsequent discharge from the ICU, discharge from the hospital, and 2-month survival after hospital discharge. Secondary endpoints were 6- and 12-month survival. Univariate and multivariate logistic regression analyses were performed to identify factors predicting outcome.

RESULTS

The median age of patients was 54 years and 48 (53%) were male. The most common reason for ICU transfer for all patients was respiratory compromise. The majority of all patients (68%) were eventually placed on ventilator support and approximately half required pressors. During the ICU course, 29 patients (32%) improved and subsequently resumed aggressive leukemia management, and 24 patients (27%) survived to be discharged from the hospital. The 2-, 6-, and 12-month overall survival was 24 (27%), 16 (18%), and 14 (16%), respectively. Higher APACHE II score, use of pressors, undergoing bone marrow transplantation preparative regimen, and adverse cytogenetics predicted worse outcome. Newly diagnosed leukemia, type of leukemia, or age did not.

CONCLUSIONS

One of 4 patients with acute leukemia survived an ICU admission to be discharged from the hospital and were alive 2 months later. A diagnosis of acute leukemia should not disqualify patients from an ICU admission.

How do hospitals deal with euthanasia requests in Flanders (Belgium)? A content analysis of policy documents

OBJECTIVE

To describe the form and content of ethics policies on euthanasia in Flemish hospitals and the possible influence of religious affiliation on policy content.

METHODS

Content analysis of policy documents.

RESULTS

Forty-two documents were analyzed. All policies contained procedures; 57% included the position paper on which the hospital's stance on euthanasia was based. All policies described their hospital's stance on euthanasia in competent terminally ill patients (n=42); 10 and 4 policies, respectively, did not describe their stance in incompetent terminally and non-terminally ill patients. Catholic hospitals restrictively applied the euthanasia law with palliative procedures and interdisciplinary deliberations. The policies described several phases of the euthanasia care process--confrontation with euthanasia request (93%), decision-making process (95%), care process in cases of no-euthanasia decision (38%), preparation and performance of euthanasia (79%), and aftercare (81%)--as well as involvement of caregivers, patients, and relatives; ethical issues; support for caregivers; reporting; and practical examples of professional attitudes and communication skills.

CONCLUSION

Euthanasia policies go beyond summarizing the euthanasia law by addressing the importance of the euthanasia care process, in which palliative care and interdisciplinary cooperation are important factors.

PRACTICE IMPLICATIONS

Euthanasia policies provide tangible guidance for physicians and nurses on handling euthanasia requests.

Health technology assessment in critical care

BACKGROUND

Heath technology assessments (HTAs) evaluate the benefits and costs of devices for monitoring and therapy (and their associated requirements for human resources) which contribute to the high expense associated with ICU admission.

DISCUSSION

Given the limited resources available for health care and increasing demands, funds spent inefficiently or unnecessarily on technologies in the ICU may threaten the sustainability of the health care system or prevent other potentially cost-effective devices from being introduced into clinical care. We discuss the factors impeding the conducting of HTAs in the ICU and suggest strategies for change.

CONCLUSIONS

Despite the need for HTAs of ICU devices only few have been conducted. They should be undertaken more frequently, and their results used to influence clinical practice and hospital and regional-level policy decisions.

Institutional ethics policies on medical end-of-life decisions: a literature review

OBJECTIVES

The responsibility of healthcare administrators for handling ethically sensitive medical practices, such as medical end-of-life decisions (MELDs), within an institutional setting has been receiving more attention. The overall aim of this paper is to thoroughly examine the prevalence, content, communication, and implementation of written institutional ethics policies on MELDs by means of a literature review.

METHODS

Major databases (Pubmed, Cinahl, PsycINFO, Cochrane Library, FRANCIS, and Philosopher's Index) and reference lists were systematically searched for all relevant papers. Inclusion criteria for relevance were that the study was empirically based and that it focused on the prevalence, content, communication, or implementation of written institutional ethics policies concerning MELDs.

RESULTS

Our search yielded 19 studies of American, Canadian, Dutch and Belgian origin. The majority of studies dealt with do-not-resuscitate (DNR) policies (prevalence: 10-89%). Only Dutch and Belgian studies dealt with policies on pain and symptom control (prevalence: 15-19%) and policies on euthanasia (prevalence: 30-79%). Procedural and technical aspects were a prime focus, while the defining of the specific roles of involved parties was unclear. Little attention was given to exploring ethical principles that question the ethical function of policies. In ethics policies on euthanasia, significant consideration was given to procedures that dealt with conscientious objections of physicians and nurses. Empirical studies about the implementation of ethics policies are scarce.

CONCLUSIONS

With regard to providing support for physicians and nurses, DNR and euthanasia policies expressed support by primarily providing technical and procedural guidelines. Further research is needed whether and in which way written institutional ethics policies on MELDs could contribute to better end-of-life care.
