Knowing when to stop: futility in the ICU

A network analysis of timing and conditions present at time of death for periviable infants (22+0-23+6 weeks) admitted to neonatal intensive care after receiving survival-focused care at birth

Introduction

Advances in neonatal care have resulted in improved survival rates for periviable infants (22 + 0-23 + 6 weeks) with increasing numbers being admitted to neonatal intensive care units across the United Kingdom. Qualitative research evidences the conflict perinatal professionals experience traversing the line between providing life-sustaining treatment to these infants, whilst not wanting to inflict a prolonged period of suffering to infants who will ultimately die. Professionals currently lack adequate prognostic tools to accurately predict pre-birth which infants will survive.

Methods

This study utilises an anonymised dataset from the North West Neonatal Network to delineate time of death profiles for periviable infants admitted to neonatal intensive care units (NICU) and explores the demographics, timing and diagnoses recorded at the time of the death.

Results

The data show that most periviable infants who died following admission to NICU died within the first seven days after birth [24 infants born at 22 weeks (65%) and 55 infants born at 23 weeks (52%)]. For infants born at 22 weeks who subsequently died on NICU, 89% had died within 14 days after birth. Reorientation of care was recorded as a relevant factor at the time of death in a minority of patients [23 infants (16%)].

Discussion

Where active, survival-focused care has been initiated, the response of the infant to intensive care and the likelihood of their survival emerges over a relatively short timeframe after admission. This lends support to a trial of therapy approach for suitable periviable infants balancing the need to avoid iatrogenic harm to infants who will ultimately die despite intensive care, whilst not denying them the chance at survival. Management of periviable deliveries requires coordinated parallel planning and a high-quality palliative care approach throughout.

Relationship of intensive care unit nurses' attitudes towards futile treatment with compassion fatigue and turnover intention

BACKGROUND

Intensive care units (ICUs) are high-stress environments where nurses frequently encounter futile treatments. These experiences can lead to compassion fatigue (CF) and increase turnover intention (TI) among ICU nurses.

AIM

To examine the levels of attitudes towards futile treatment (ATFT), CF and TI among ICU nurses, to explore their relationship and identify the factors influencing ATFT.

STUDY DESIGN

This cross-sectional study involved 440 ICU nurses who were members of the Turkish Society of Critical Care Nurses. Data were collected via an online survey using the Attitudes Towards Futile Treatment Scale (ATFTS), Compassion Fatigue-Short Scale (CFS) and Turnover Intention Scale (TIS). Descriptive statistics, correlation analyses and hierarchical regression analyses were conducted to analyse the data.

RESULTS

The findings of the study indicated that ICU nurses' ATFTS, CFS and TIS scores were 43.18 ± 6.44, 74.25 ± 23.33 and 8.39 ± 3.03, respectively. There was a significant negative correlation between ATFTS and CFS (r = -0.428, p = .001) as well as TIS (r = -0.204, p = .029). In the final hierarchical regression model, the significant predictors of ATFTS included participation in patient-related decisions (β = -0.148, p = .001), performing futile treatment practices (β = 0.342, p = .001), work burnout (β = -0.165, p = .015), secondary trauma (β = -0.130, p = .011) and TI (β = -0.170, p = .039).

CONCLUSION

This study found that ICU nurses' ATFTs are negatively correlated with compassion fatigue and turnover intention. Enhancing ICU nurses' involvement in decision-making and providing psychological and emotional support to manage compassion fatigue and turnover intention may help improve their attitudes towards futile treatment.

RELEVANCE TO CLINICAL PRACTICE

The study highlights the critical need to address compassion fatigue and turnover intention among intensive care unit (ICU) nurses to mitigate their negative attitudes towards futile treatments. By improving emotional resilience and involving nurses more actively in ethical decision-making processes, health care institutions can enhance the quality of care provided in ICUs, reduce turnover rates and ultimately support the well-being of the nursing staff.

Collective Reflective Equilibrium, Algorithmic Bioethics and Complex Ethics

John Harris has made many seminal contributions to bioethics. Two of these are in the ethics of resource allocation. Firstly, he proposed the "fair innings argument" which was the first sufficientarian approach to distributive justice. Resources should be provided to ensure people have a fair innings-when Harris first wrote this, around 70 years of life, but perhaps now 80. Secondly, Harris famously advanced the egalitarian position in response to utilitarian approaches to allocation (such as maximizing Quality Adjusted Life Years [QALYs]) that what people want is the greatest chance of the longest, best quality life for themselves, and justice requires treating these claims equally. Harris thus proposed both sufficientarian and egalitarian approaches. This chapter compares these approaches with utilitarian and contractualist approaches and provides a methodology for deciding among these (Collective Reflective Equilibrium). This methodology is applied to the allocation of ventilators in the pandemic (as an example) and an ethical algorithm for their deployment created. This paper describes the concept of algorithmic bioethics as a way of addressing pluralism of values and context specificity of moral judgment and policy, and addressing complex ethics.

Exploring the ethical decision-making experience of caregivers of end stage cancer patients in Iran: a phenomenological study

BACKGROUND

Ethical decision making is a complex issue because it strongly depends on the religion, beliefs, traditional laws and moral views of each society. The purpose of this study was to explore the experience of Iranian family caregivers of end stage cancer patients about ethical decision making.

METHODS

This qualitative study is based on van Manen's method of hermeneutic phenomenology. In-depth interviews were carried out to collect data. Participants were 12 caregiver. Audiotapes were transcribed and analyzed for common themes that represented the participants' experiences. Trustworthiness of the findings was established using the Lincoln and Guba's criteria.

RESULTS

Three themes reflected the essence of caregivers' lived experience including; fluctuating between hope and despair, wandering dilemma, and ethical decision making. Each of these themes consisted of several subthemes.

CONCLUSION

The present study revealed that, the caregivers of terminally ill cancer patients need different information about prognosis and end of life decision making process. Our perception of how families negotiate ethical issues in their decision-making is still developing. Opportunities should be created to empowering caregivers to talk about their uncertainties and concerns.

Wish to die trying to live: unwise or incapacitous? The case of University Hospitals Birmingham NHS Foundation Trust versus 'ST'

The recent legal dispute about medical treatment for a 19-year-old patient, Sudiksha Thirumalesh, (known initially by the Court of Protection as 'ST') in A NHS Trust versus ST & Ors (2023) raised several challenging ethical issues. While Sudiksha's case bears similarities to other high-profile cases in England and Wales, there are key differences. Crucially, Sudiksha herself was part of the disagreement. She was alert, communicative and sought to advocate for herself. Furthermore, this case was framed in the courts as pivoting not on considerations of best interests but on a determination of decisional capacity. Sudiksha was deemed to lack capacity because she did not believe her doctors' view of her prognosis.While the legal questions in the case were central to a recent Court of Appeal decision (which overturned the original finding), in this commentary, we focus on the ethical questions therein. We start by describing Sudiksha's court case and the initial judgment. We then offer an ethical analysis of the relationship between false beliefs, values and the 'capacity' to make decisions, arguing for a need for particular care when judging patients to lack capacity based purely on 'false and fixed beliefs'. After briefly noting the legal basis for the appeal finding, we offer ethical implications for future cases. Although it appears that Sudiksha had decision-making capacity, this did not settle the ethical question of whether health professionals were obliged to continue treatment that they believed to have no prospect of success.

Conscientious Objection and the Anesthesiologist: An Ethical Dilemma

Conscientious objection is a legally protected right of medical professionals to recuse themselves from patient care activities that conflict with their personal values. Anesthesiology is different from most specialties with respect to conscientious objection in that the focus is to facilitate safe, efficient, and successful performance of procedures by others, rather than to perform the treatment in question. This could give rise to a unique, somewhat indirect ethical tension between the application of conscientious objection and potential infringement upon patient autonomy and well-being. While some situations have clear grounds and precedent for conscientious objection (e.g., abortion, or futile procedures), newer procedures, such as gender-affirming surgery and xenotransplantation, may trigger conscientious objection for complex reasons. This review discusses ethical, legal, and practical aspects of conscientious objection; challenges to anesthesia groups, departments, and healthcare organizations when conscientious objection is invoked by anesthesiologists; and strategies to help mitigate the ethical dilemmas.

Medical futility at the end of life: the first qualitative study of ethical decision-making methods among Turkish doctors

BACKGROUND

The swift advancement of intensive care medicine, coupled with technological possibilities, has prompted numerous ethical inquiries regarding decision-making processes concerning the withholding or withdrawal of treatment due to medical futility. This study seeks to delineate the decision-making approaches employed by intensive care physicians in Türkiye when faced with medical futility at the end of life, along with an ethical evaluation of these practices.

METHODS

Grounded theory, a qualitative analysis method was employed, conducting semi-structured, in-depth interviews with eleven intensive care physicians in Türkiye. The subsequent text analysis was carried out using MAXQDA software.

RESULTS

Participants assert that the decisions made by Turkish physicians determine whether treatment is futile, rely on medical consensus, and lack a standardized decision-making process. The decisions are influenced by legal and social pressures, resource constraints, and occasional conflicts of interest. The significance of professional hierarchy is notable, with limited consideration given to the opinions of nurses and other staff. The unstructured medical consensus processes are shaped by normative concepts such as benefit, age, justice, and conscience. Furthermore, it was observed that the conscientious opinions of physicians carry more weight than adherence to ethical principles and guidelines.

CONCLUSION

To create optimal conditions for doctors to make ethically justifiable decisions, the dynamics within the treatment team should be improved, emphasizing the minimization of hierarchy, and ensuring the active participation of all team members in the decision-making process. Additionally, efforts should be directed toward narrowing the gap between the conscience of the individual doctor and established ethical principles. A potential solution lies in the nationwide implementation of clinical ethics committees and the establishing of clinical ethics guidelines, aiming to address, and overcome the identified challenges.

Withdrawing Assisted Nutrition in Neonates: A Survey on Attitudes and Insights in Argentina

OBJECTIVE

This study aimed to assess beliefs and attitudes of Argentinean neonatologists and neonatal nurses regarding end-of-life care of newborn infants, including withdrawal of clinically assisted nutrition and hydration (CANH).

STUDY DESIGN

A five-domain survey was sent to 465 neonatal health care workers, which included demographic data, general ethical concepts, participation in end-of-life decisions, beliefs about end-of-life care practices, and presentation of four clinical scenarios. Standard statistical tests were used, and a multivariable analysis was done to evaluate variables independently associated with rejecting the withdrawal of CANH.

RESULTS

A total of 227 questionnaires were anonymously completed, 60% by physicians and 40% by nurses. More respondents agreed to withdraw mechanical ventilation in comparison to CANH in patients under certain circumstances (88 vs. 62%, p < 0.01). The most accepted variables when deciding to withdraw care were the quality of life perceived by parents (86%) and their religious beliefs (73%). A total of 93% agreed that parents should be included in the decision, but only 74% acknowledged they are included in real practice. Considering the scenario of a newborn with severe and irreversible neurological compromise, 46% of respondents were opposed to suspending enteral nutrition. No independent variables were found to be associated with opposing the withdrawal of CANH. Of those agreeing to withdraw enteral feeds under certain circumstances, for the severely neurologically affected neonate 58% would either refuse to limit enteral feeds or consult with an ethics committee before doing so. When given the scenario of their own severe and irreversible neurological compromise, 68% agreed to have enteral feeds withdrawn to themselves, and they were more likely to agree with withdrawing feeds for the severely compromised neonate (odds ratio: 7.2; 95% confidence interval: 2.7-24.1).

CONCLUSION

While most health care providers agreed to withdraw life-sustaining support under certain conditions, many were reluctant to suspend CANH. Many responses differed when being asked as general statements versus actual clinical scenarios.

KEY POINTS

· Withdrawal of assisted nutrition is supported by the American Academy of Pediatrics in certain scenarios.. · Many neonatal intensive care units health care providers from Argentina are reluctant to suspend assisted nutrition.. · There is a need to learn how to deal with complex bioethical issues..

Futile treatment - when is enough, enough?

Objective This paper examines two aspects of treatment decision making: withdrawal of treatment decisions made by a patient; and decisions to not proceed with treatment by a health professional. The paper aims to provide an overview of the law relating to the provision of treatment, then highlight the uncertainty as to the meaning of and costs associated with futile treatment. Methods The paper reviews the current legal and medical literature on futile treatment. Results Continuing treatment which is futile is not in the patient's best interests. Futility may be understood in both quantitative and qualitative terms. Recent legal cases have expanded the definition of futility to focus not on the nature of the treatment itself, but also on the health of the patient to whom treatment is provided. Conclusions As Australia's population ages, there is likely to be an increased focus on the allocation of scarce health resources. This will, inevitably, place constraints on the number and variety of treatments offered to patients. The level of constraint will be felt acutely where a proposed treatment offers little clinical efficacy. It is time to try to understand and agree on a workable definition of futility.

Becoming futile: the emotional pain of treating COVID-19 patients

Introduction

The COVID-19 pandemic has had a profoundly detrimental impact on the emotional wellbeing of health care workers. Numerous studies have shown that their rates of the various forms of work-related distress, which were already high before the pandemic, have worsened as the demands on health care workers intensified. Yet much less is known about the specific social processes that have generated these outcomes. This study adds to our collective knowledge by focusing on how one specific social process, the act of treating critically ill COVID-19 patients, contributed to emotional pain among health care workers.

Methods

This article draws from 40 interviews conducted with intensive care unit (ICU) staff in units that were overwhelmed with COVID-19 patients. The study participants were recruited from two suburban community hospitals in Massachusetts and the interviews were conducted between January and May 2021.

Results

The results show that the uncertainty over how to treat critically ill COVID-19 patients, given the absence of standard protocols combined with ineffective treatments that led to an unprecedented number of deaths caused significant emotional pain, characterized by a visceral, embodied experience that signaled moral distress, emotional exhaustion, depersonalization, and burnout. Furthermore, ICU workers' occupational identities were undermined as they confronted the limits of their own abilities and the limits of medicine more generally.

Discussion

The inability to save incurable COVID-19 patients while giving maximal care to such individuals caused health care workers in the ICU an immense amount of emotional pain, contributing to our understanding of the social processes that generated the well-documented increase in moral distress and related measures of work-related psychological distress. While recent studies of emotional socialization among health care workers have portrayed clinical empathy as a performed interactional strategy, the results here show empathy to be more than dramaturgical and, in this context, entailed considerable risk to workers' emotional wellbeing.

Limitation of Non-Beneficial Interventions and their Impact on the Intensive Care Unit Costs

Introduction

Using a plan to limit non-beneficial life support interventions has significantly reduced harm and loss of dignity for patients at the end of life. The association of these limitations with patients' clinical characteristics and health care costs in the intensive care unit (ICU) needs further scientific evidence.

Aim of the study

To explore decisions to limit non-beneficial life support interventions, their correlation with patients' clinical data, and their effect on the cost of care in the ICU.

Material and Methods

We included all patients admitted to the general ICU of a hospital in Greece in a two-year (2019-2021) prospective study. Data collection included patient demographic and clinical variables, data related to decisions to limit (withholding, withdrawing) non-beneficial interventions (NBIs), and economic data. Comparisons were made between patients with and without limitation decisions.

Results

NBIs were limited in 164 of 454 patients (36.12%). Patients with limitation decisions were associated with older age (70y vs. 62y; p<0,001), greater disease severity score (APACHE IV, 71 vs. 50; p<0,001), longer length of stay (7d vs. 4.5d; p<0,001), and worse prognosis of death (APACHE IV PDR, 48.9 vs. 17.35; p<0,001). All cost categories and total cost per patient were also higher than the patient without limitation of NBIs (9247,79€ vs. 8029,46€, p<0,004). The mean daily cost has not differed between the groups (831,24€ vs. 832,59€; p<0,716). However, in the group of patients with limitations, all cost categories, including the average daily cost (767.31€ vs. 649.12€) after the limitation of NBIs, were reduced to a statistically significant degree (p<0.001).

Conclusions

Limiting NBIs in the ICU reduces healthcare costs and may lead to better management of ICU resource use.

What do we know about experiencing end-of-life in burn intensive care units? A scoping review

OBJECTIVES

The aim of this article is to review and synthesize the evidence on end-of-life in burn intensive care units.

METHODS

Systematic scoping review: Preferred Reporting Items for Systemic Reviews extension for Scoping Reviews was used as a reporting guideline. Searches were performed in 3 databases, with no time restriction and up to September 2021.

RESULTS

A total of 16,287 documents were identified; 18 were selected for analysis and synthesis. Three key themes emerged: (i) characteristics of the end-of-life in burn intensive care units, including end-of-life decisions, decision-making processes, causes, and trajectories of death; (ii) symptom control at the end-of-life in burn intensive care units focusing on patients' comfort; and (iii) concepts, models, and designs of the care provided to burned patients at the end-of-life, mainly care approaches, provision of care, and palliative care.

SIGNIFICANCE OF RESULTS

End-of-life care is a major step in the care provided to critically ill burned patients. Dying and death in burn intensive care units are often preceded by end-of-life decisions, namely forgoing treatment and do-not-attempt to resuscitate. Different dying trajectories were described, suggesting the possibility to develop further studies to identify triggers for palliative care referral. Symptom control was not described in detail. Palliative care was rarely involved in end-of-life care for these patients. This review highlights the need for early and high-quality palliative and end-of-life care in the trajectories of critically ill burned patients, leading to an improved perception of end-of-life in burn intensive care units. Further research is needed to study the best way to provide optimal end-of-life care and foster integrated palliative care in burn intensive care units.

From Bridge to Destination? Ethical Considerations Related to Withdrawal of ECMO Support over the Objections of Capacitated Patients

Extracorporeal membrane oxygenation (ECMO) is typically viewed as a time-limited intervention-a bridge to recovery or transplant-not a destination therapy. However, some patients with decision-making capacity request continued ECMO support despite a poor prognosis for recovery and lack of viability as a transplant candidate. In response, critical care teams have asked for guidance regarding the ethical permissibility of unilateral withdrawal over the objections of a capacitated patient. In this article, we evaluate several ethical arguments that have been made in favor of withdrawal, including distributive justice, quality of life, patients' rights, professional integrity, and the Equivalence Thesis. We find that existing justifications for unilateral withdrawal of ECMO support in capacitated patients are problematic, which leads us to conclude that either: (1) additional ethical arguments are necessary to defend this approach or (2) the claim that it is not appropriate to use ECMO as a destination therapy should be questioned.

Characteristics of Critically Ill Infants at the End of Life in the Neonatal Intensive Care Unit

Objectives: About 16,000 infants die in the neonatal intensive care unit (NICU) each year with many experiencing invasive medical treatments and high number of symptoms.1 To inform better management, we characterized diagnoses, symptoms, and patterns of care among infants who died in the NICU. Method: Retrospective electronic medical record (EMR) review of 476 infants who died following admission to a large regional level IV NICU in the United States over a 10-year period. Demographic, symptom, diagnosis, treatment, and end-of-life characteristics were extracted. Results: About half of infants were male (55.9%, n = 266), average gestational age was 31.3 weeks (standard deviation [SD] = 6.5), and average age at death was 40.1 days (SD = 84.5; median = 12; range: 0-835). Race was documented for 65% of infants, and most were White (67.0%). One-third of infants (n = 138) were seen by fetal medicine. Most infants experienced pain through both the month and week before death (79.6%), however, infants with necrotizing enterocolitis had more symptoms in the week before death. Based on EMR, infants had more symptoms, and received more medical interventions and comfort measures during the week before death compared with the month prior. Only 35% (n = 166) received a palliative care referral. Conclusions: Although the medical profiles of infants who die in the NICU are complex, the overall number of symptoms was less than in older pediatric populations. For infants at high risk of mortality rate, providers should assess for common symptoms over time. To manage symptoms as effectively as possible, both timely and continuous communication with parents and early referral to palliative care are recommended.

Agreement between Family Members and the Physician's View in the ICU Environment: Personal Experience as a Factor Influencing Attitudes towards Corresponding Hypothetical Situations

BACKGROUND

It is not known whether intensive care unit (ICU) patients' family members realistically assess patients' health status.

OBJECTIVES

The aim was to investigate the agreement between family and intensivists' assessment concerning changes in patient health, focusing on family members' resilience and their perceptions of decision making.

METHODS

For each ICU patient, withdrawal criteria were assessed by intensivists while family members assessed the patient's health development and completed the Connor-Davidson Resilience Scale and the Self-Compassion Scale. Six months after ICU discharge, follow-up contact was established, and family members gave their responses to two hypothetical scenarios.

RESULTS

162 ICU patients and 189 family members were recruited. Intensivists' decisions about whether a patient met the withdrawal criteria had 75,9% accuracy for prediction of survival. Families' assessments were statistically independent of intensivists' opinions, and resilience had a significant positive effect on the probability of agreement with intensivists. Six months after discharge, family members whose relatives were still alive were significantly more likely to consider that the family or patient themselves should be involved in decision-making.

CONCLUSIONS

Resilience is related to an enhanced probability of agreement of the family with intensivists' perceptions of patients' health progression. Family attitudes in hypothetical scenarios were found to be significantly affected by the patient's actual health progression.

Relationship Between Physician's and Nurses' Attitudes Towards Futile Treatment and Their Approach to Death and Terminally Ill Patients

We aimed to determine the relationship between the attitudes of healthcare professionals towards futile treatment and their approach to death and terminally ill patients. We collected the data from nurses-physicians working in the intensive care unit, using the Nurses' Attitudes towards Futile Treatment Scale (NAFTS) and Approach to Death and Dying Patients Attitude Scale (ADDPAS). Avoidant attitudes displayed towards death and terminally ill patients increase as futile treatment is administered more. Health workers who work in the intensive care unit and witness futile treatment more frequently in the clinic are of the opinion that futile treatment should not be performed.

Impact of healthcare strain on access to mechanical ventilation and mortality of hospitalized COVID-19 patients: a retrospective cohort study

OBJECTIVE

Healthcare saturation has been a prominent worry during the COVID-19 pandemic. Increase of hospital beds with mechanical ventilators has been central in Mexico's approach, but it is not known whether this actually improves access to care and the resulting quality of it. This study aimed to determine the impact of healthcare strain and other pre-specified variables on dying from coronavirus disease 2019 (COVID-19) without receiving invasive mechanical ventilation (IMV).

METHODS

A retrospective cohort study was conducted using open data from Mexico City between 8 May 2020 and 5 January 2021. We performed Cox proportional hazards models to identify the strength of the association between proposed variables and the outcomes.

RESULTS

Of 33 797 hospitalized patients with suspected or confirmed COVID-19, 19 820 (58.6%) did not require IMV and survived, 5414 (16.1%) required IMV and were intubated and 8563 (25.3%) required IMV but died without receiving it. A greater occupation of IMV-capable beds increased the hazard of death without receiving IMV (hazard ratio [HR] 1.56, comparing 90% with 50% occupation). Private healthcare was the most protective factor for death without IMV (HR 0.14).

CONCLUSIONS

Higher hospital bed saturation increased the hazard of dying without being intubated and worsened the outcomes among mechanically ventilated patients. Older age also increased the hazard of the outcomes, while private healthcare dramatically decreased them.

The virtual uncertainty of futility in emergency surgery

Futility is a controversial topic within surgery. This editorial defines the concept, explains the differing types of surgical futility, and discusses the ethical issues around the subject.

Modelling futility in the setting of fertility treatment

When is a fertility treatment futile? This question has great practical importance, given the role futility plays in ethical, legal and clinical discussions. Here, we outline a novel method of determining futility for IVF treatments. Our approach is distinctive for considering the economic value attached to the intended aim of IVF treatments, i.e. the birth of a child, rather than just the effects on prospective parents and the health system in general. We draw on the commonly used metric, quality-adjusted life years (QALYs), to attach a monetary value to new lives created through IVF. We then define futility as treatments in which the chance of achieving a live birth is so low that IVF is no longer a cost-effective intervention given the economic value of new births. This model indicates that IVF treatments in which the chance of a live birth are <0.3% are futile. This suggests IVF becomes futile when women are aged between 47 and 49 years of age. This is notable older than ages currently considered as futile in an Australian context (∼45). In the UK, government subsidized treatment with the couple's own gametes stops at the age of 42, while privately funded treatments are self-regulated by individual providers. In most European countries and the USA, the 'age of futility' is likewise managed by clinical consensus.

Why the term 'persistent therapy' is not worse than the term 'medical futility'

The discussion around the use of the term 'medical futility' began in the late 1980s. The Polish Working Group on End-of-Life Ethics (PWG) joined this discussion in 2008. They offered their own approach to the issues regarding medical futility based on the category of persistent therapy. According to the PWG, 'persistent therapy is the use of medical procedures to maintain the life function of the terminally ill in a way that prolongs their dying, introducing excessive suffering or violating their dignity'. In this paper I attempt to show that the term 'persistent therapy' is neither worse nor better than the term 'medical futility', but it captures different aspects and nuances. Additionally, the Polish social and religious background plays a significant role in shaping the category of persistent therapy.

The false dichotomy of surgical futility in the emergency laparotomy setting: scoping review

BACKGROUND

Futile is defined as 'the fact of having no effect or of achieving nothing'. Futility in medicine has been defined through seven guiding principles, which in the context of emergency surgery, have been relatively unexplored. This scoping review aimed to identify key concepts around surgical futility as it relates to emergency laparotomy.

METHODS

Using the Arksey and O'Malley framework, a scoping review was conducted. A search of the Cochrane Library, Google Scholar, MEDLINE, and Embase was performed up until 1 November 2021 to identify literature relevant to the topic of futility in emergency laparotomy.

RESULTS

Three cohort studies were included in the analysis. A total of 105 157 patients were included, with 1114 patients reported as futile. All studies were recent (2019 to 2020) and focused on the principle of quantitative futility (assessment of the probability of death after surgery) within a timeline after surgery: two defining futility as death within 48 hours of surgery and one as death within 72 hours. In all cases this was derived from a survival histogram. Predictors of defined futile procedures included age, level of independence prior to admission, surgical pathology, serum creatinine, arterial lactate, and pH.

CONCLUSION

There remains a paucity of research defining, exploring, and analysing futile surgery in patients undergoing emergency laparotomy. With limited published work focusing on quantitative futility and the binary outcome of death, research is urgently needed to explore all principles of futility, including the wishes of patients and their families.

Relational dynamics involved in therapeutic discordance among prescribers and patients: A Grounded Theory study

OBJECTIVE

No studies have explored the negative process of concordance: discordance in prescribing-medication-taking. This study provides a deeper understanding of discordance as a co-constructed process among patients and prescribers.

METHODS

To explore the question "what psychological and relational processes are involved when therapeutic discordance among prescribers and receivers occurs?" a constructivist Grounded Theory study was carried out through semi-structured interviews with patients and their medical doctors.

RESULTS

The final sample of our study was composed of 29 participants: 16 receivers and 13 prescribers. "Neglecting the relationship", the core category, shapes the therapeutic discordance and connects three main conceptual phases: signing a non-negotiating contract, acting alone, and establishing a superficial relationship.

CONCLUSION

Our grounded theory conceptualization contributes to the concordance-related debate by evidencing the processes among prescribers and receivers in interwoven actions. It offers another dimension to how notions of compliance, adherence and concordance have been theorized to date.

PRACTICE IMPLICATIONS

More than one interaction with receivers is recommended. If there are hints that conflict potentially is compromising the relationship, prescribers should involve intermediaries. Setting aside for a moment, evidence-based justification for treatments and trying to understand prescribers' motivations may boost a positive change.

Frailty Triage: Is Rationing Intensive Medical Treatment on the Grounds of Frailty Ethical?

In early 2020, a number of countries developed and published intensive care triage guidelines for the pandemic. Several of those guidelines, especially in the UK, encouraged the explicit assessment of clinical frailty as part of triage. Frailty is relevant to resource allocation in at least three separate ways, through its impact on probability of survival, longevity and quality of life (though not a fourth-length of intensive care stay). I review and reject claims that frailty-based triage would represent unjust discrimination on the grounds of age or disability. I outline three important steps to improve the ethical incorporation of frailty into triage. Triage criteria (ie frailty) should be assessed consistently in all patients referred to the intensive care unit. Guidelines must make explicit the ethical basis for the triage decision. This can then be applied, using the concept of triage equivalence, to other (non-frail) patients referred to intensive care.

Navigating the Minefield: Managing Refusal of Medical Care in Older Adults with Chronic Symptoms of Mental Illness

Purpose

The purpose of this case series is to illustrate the complexity of considerations across health (physical and mental), ethical, human rights and practical domains when an older adult with chronic symptoms of mental illness refuses treatment for a serious medical comorbidity. A broad understanding of these considerations may assist health care professionals in navigating this challenging but common aspect of clinical practice.

Case Presentation

Three detailed case reports are described. Participants were older adults with an acute presentation of a chronic mental illness, admitted to a specialized older persons mental health inpatient unit (OPMHU) in an Australian metropolitan hospital. Significant comorbid medical issues were detected or arose during the admission and the patient refused the recommended medical intervention. Data extracted from patients' medical records were analyzed and synthesized into detailed case reports using descriptive techniques. Each patient was assessed as lacking capacity for healthcare and treatment consent and did not have relatives or friends to assist with supported decision-making. Multifaceted aspects of decision-making and management are highlighted.

Conclusion

There are multiple complex issues to consider when an older adult with chronic symptoms of mental illness refuses treatment for serious comorbid medical conditions. In addition to optimizing management of the underlying mental illness (which may be impairing capacity to make healthcare decisions), clinicians should adopt a role of advocacy for their patients in considering the potential impact of ageism and stigma on management plans and inequities in physical healthcare. Consultation with specialist medical teams should incorporate multifaceted considerations such as potentially inappropriate treatment and optimum setting of care. Equally important is reflective practice; considering whether treatment decisions may infringe upon human rights or cause trauma.

Cost of Futile ICU Care in One Ontario Hospital

Critical care is a costly and finite resource that provides the ability to manage patients with life-threatening illnesses in the most advanced forms available. However, not every condition benefits from critical care. There are unrecoverable health states in which it should not be used to perpetuate. Such situations are considered futile. The determination of medical futility remains controversial. In this study we describe the length of stay (LOS), cost, and long-term outcomes of 12 cases considered futile and that have been or were considered for adjudication by Ontario’s Consent and Capacity Board (CBB). A chart review was undertaken to identify patients admitted to the Intensive Care Unit (ICU), whose care was deemed futile and cases were considered for, or brought before the CCB. Costs for each of these admissions were determined using the case-costing system of The Ottawa Hospital Data Warehouse. All 12 patients identified had a LOS of greater than 4 months (range: 122-704 days) and a median age 83.5 years. Seven patients died in hospital, while 5 were transferred to long term or acute care facilities. All patients ultimately died without returning to independent living situations. The total cost of care for these 12 patients was $7 897 557.85 (mean: $658 129.82). There is a significant economic cost of providing resource-intensive critical care to patients in which these treatments are considered futile. Clinicians should carefully consider the allocation of finite critical care resources in order to utilize them in a way that most benefits patients.

The Community Perspective on Potentially Inappropriate Treatment

Rationale: Medical interventions that prolong life without achieving an effect that the patient can appreciate as a benefit are often considered futile or inappropriate by healthcare providers. In recent years, a multicenter guideline has been released with recommendations on how to resolve conflicts between families and clinicians in these situations and to increase public engagement. Although laypeople are acknowledged as important stakeholders, their perceptions and understanding of the terms "potentially inappropriate" or "futile" treatment have received little formal evaluation.Objectives: To evaluate the community perspective about the meaning of futile treatment.Methods: Six focus groups (two groups each of ages <65, 65-75, and >75 yr) were convened to explore what constitutes futile treatment and who should decide in situations of conflict between doctors and families. Focus group discussions were analyzed using grounded theory.Results: There were 39 participants aged 18 or older with at least one previous hospitalization (personal or by immediate relative). When asked to describe futile or inappropriate treatment, community members found the concept difficult to understand and the terminology inadequate, though when presented with a case describing inappropriate treatment, most participants recognized it as the provision of inappropriate treatment. Several themes emerged regarding participant difficulty with the concept, including inadequate physician-patient communication, lack of public emphasis on end-of-life issues, skepticism that medical treatment can be completely inappropriate, and doubts and fears that medical futility could undermine patient and/or family autonomy. Participants also firmly believed that in situations of conflict families should be the ultimate decision-makers.Conclusions: Public engagement in policy development and discourse around medical futility will first require intense education to familiarize the lay public about use of inappropriate treatment at the end of life.

Inter-physician variability in strategies linked to treatment limitations after severe traumatic brain injury; proactivity or wait-and-see

BACKGROUND

Prognostic uncertainty is a challenge for physicians in the neuro intensive care field. Questions about whether continued life-sustaining treatment is in a patient's best interests arise in different phases after a severe traumatic brain injury. In-depth information about how physicians deal with ethical issues in different contexts is lacking. The purpose of this study was to seek insight into clinicians' strategies concerning unresolved prognostic uncertainty and their ethical reasoning on the issue of limitation of life-sustaining treatment in patients with minimal or no signs of neurological improvement after severe traumatic brain injury in the later trauma hospital phase.

METHODS

Interviews with 18 physicians working in a neurointensive care unit in a large Norwegian trauma hospital, followed by a qualitative thematic analysis focused on physicians' strategies related to treatment-limiting decision-making.

RESULTS

A divide between proactive and wait-and-see strategies emerged. Notwithstanding the hospital's strong team culture, inter-physician variability with regard to ethical reasoning and preferred strategies was exposed. All the physicians emphasized the importance of team-family interactions. Nevertheless, their strategies differed: (1) The proactive physicians were open to consider limitations of life-sustaining treatment when the prognosis was grim. They initiated ethical discussions, took leadership in clarification and deliberation processes regarding goals and options, saw themselves as guides for the families and believed in the necessity to prepare families for both best-case and worst-case scenarios. (2) The "wait-and-see" physicians preferred open-ended treatment (no limitations). Neurologically injured patients need time to uncover their true recovery potential, they argued. They often avoided talking to the family about dying or other worst-case scenarios during this phase.

CONCLUSIONS

Depending on the individual physician in charge, ethical issues may rest unresolved or not addressed in the later trauma hospital phase. Nevertheless, team collaboration serves to mitigate inter-physician variability. There are problems and pitfalls to be aware of related to both proactive and wait-and-see approaches. The timing of best-interest discussions and treatment-limiting decisions remain challenging after severe traumatic brain injury. Routines for timely and open discussions with families about the range of ethically reasonable options need to be strengthened.

Moral distress in end-of-life decisions: A qualitative study of intensive care physicians

PURPOSE

The purpose is to explore triggers for moral distress, constraints preventing physicians from doing the right thing and ensuing consequences in making decisions for patients approaching end of life in intensive care.

MATERIALS AND METHODS

The qualitative study was undertaken in a tertiary referral intensive care unit in Northern Ireland in the United Kingdom. Drawing upon patient case studies of decisions about non escalation and/or withdrawal of life support, we undertook indepth interviews with senior and junior physicians. Interviews were transcribed verbatim and narratively analysed.

RESULTS

Eighteen senior and junior physicians involved in 21 patient case studies were interviewed. Analysis determined two predominant themes: key moral distress triggers; and strategies and consequences. Junior residents reported most instances of moral distress, triggered by perceived futility, lack of continuity, protracted decisions and failure to ensure 'good death'. Senior physicians' triggers included constraint of clinical autonomy. Moral distress was far reaching, affecting personal life, working relationships and career choice.

CONCLUSION

This study is the first to explore physicians' moral distress in end-of-life decisions in intensive care via a narrative inquiry approach using case studies. Results have implications for the education, recruitment and retention of physicians, relevant in the Covid 19 pandemic.

Practices in Triage and Transfer of Critically Ill Patients: A Qualitative Systematic Review of Selection Criteria

OBJECTIVES

To identify and appraise articles describing criteria used to prioritize or withhold a critical care admission.

DATA SOURCES

PubMed, Embase, Medline, EBM Reviews, and CINAHL Complete databases. Gray literature searches and a manual review of references were also performed. Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines were followed.

STUDY SELECTION

We sought all articles and abstracts of original research as well as local, provincial, or national policies on the topic of ICU resource allocation. We excluded studies whose population of interest was neonatal, pediatric, trauma, or noncritically ill. Screening of 6,633 citations was conducted.

DATA EXTRACTION

Triage and/or transport criteria were extracted, based on type of article, methodology, publication year, and country. An appraisal scale was developed to assess the quality of identified articles. We also developed a robustness score to further appraise the robustness of the evidence supporting each criterion. Finally, all criteria were extracted, evaluated, and grouped by theme.

DATA SYNTHESIS

One-hundred twenty-nine articles were included. These were mainly original research (34%), guidelines (26%), and reviews (21%). Among them, we identified 200 unique triage and transport criteria. Most articles highlighted an exclusion (71%) rather than a prioritization mechanism (17%). Very few articles pertained to transport of critically ill patients (4%). Criteria were classified in one of four emerging themes: patient, condition, physician, and context. The majority of criteria used were nonspecific. No study prospectively evaluated the implementation of its cited criteria.

CONCLUSIONS

This systematic review identified 200 criteria classified within four themes that may be included when devising triage programs including the coronavirus disease 2019 pandemic. We identified significant knowledge gaps where research would assist in improving existing triage criteria and guidelines, aiming to decrease arbitrary decisions and variability.

Change in inappropriate critical care over time

PURPOSE

Intensive care interventions that prolong life without achieving meaningful benefit are considered clinically "inappropriate". In 2012, the frequency of perceived-inappropriate critical care was 10.8% at one academic health system; and we aimed to re-evaluate this frequency.

METHODS

For 4 months in 2017, we surveyed critical care physicians daily and asked whether each patient was receiving appropriate, probably inappropriate, or inappropriate critical care. Patients were categorized into three groups: 1) patients for whom treatment was never inappropriate, 2) patients with at least one assessment that treatment was probably inappropriate, but no inappropriate treatment assessments, and 3) patients who had at least one assessment of inappropriate treatment.

RESULTS

Fifty-five physicians made 10,105 assessments on 1424 patients. Of these, 94 (6.6%) patients received at least one assessment of inappropriate critical care, which is lower than 2012 (10.8% (p < 0.01)). Comparing 2017 and 2012, patient age, MS-DRG, length of stay, and hospital mortality were not significantly different (p > 0.05). Inpatient mortality in 2017 was 73% for patients receiving inappropriate critical care.

CONCLUSIONS

Over five years the proportion of patients perceived to be receiving inappropriate critical care dropped by 40%. Understanding the reasons for such change might elucidate how to continue to reduce inappropriate critical care.

Appropriateness of intensive care treatments near the end of life during the COVID-19 pandemic

The patient and family perspective on the appropriateness of intensive care unit (ICU) treatments involves preferences, values and social constructs beyond medical criteria. The clinician's perception of inappropriateness is more reliant on clinical judgment. Earlier consultation with families before ICU admission and patient education on the outcomes of life-sustaining therapies may help reconcile these provider-patient disagreements. However, global emergencies like COVID-19 change the usual paradigm of end-of-life care, as it is a new disease with only scarce predictive information about it. Pandemics can also bring about the burdensome predicament of doctors having to make unwanted choices of rationing access to the ICU when demand for otherwise life-saving resources exceeds supply. Evidence-based prognostic checklists may guide treatment triage but the principles of shared decision-making are unchanged. Yet, they need to be altered with respect to COVID-19, defining likely outcomes and likelihood of benefit for the patient, and clarifying their willingness to take on the risks inherent to being in an ICU for 2 weeks for those eligible. For patients who are admitted during the prodrome of COVID-19 disease, or those who deteriorate in the second week, clinicians have some lead time in hospital to have appropriate discussions about ceilings of treatments offered based on severity.

KEY POINTS

The patient and family perspective on inappropriateness of intensive care at the end of life often differs from the clinician's opinion due to the nonmedical frame of mind.To improve satisfaction with communication on treatment goals, consultation on patient values and inclusion of social constructs in addition to clinical prediction is a good start to reconcile differences between physician and health service users' viewpoints.During pandemics, where health systems may collapse, different admission criteria driven by the need to ration services may be warranted.

EDUCATIONAL AIMS

To explore the extent to which older patients and their families are involved in decisions about appropriateness of intensive care admission or treatmentsTo understand how patients or their families define inappropriate intensive care admission or treatmentsTo reflect on the implications of decision to admit or not to admit to the intensive care unit in the face of acute resource shortages during a pandemic.

Conceptualizations of consciousness and continuation of care among family members and health professionals caring for patients in a minimally conscious state

BACKGROUND

The American Academy of Neurology recently emphasized the importance of communicating with patients' families to better reflect patient values in clinical care. However, little is known about how decisions about continuing rehabilitative care made by family caregivers and healthcare providers working with minimally conscious patients are informed by conceptualizations of consciousness and moral status.

METHODS

We explored these issues in interviews with 18 family caregivers and 20 healthcare professionals caring for minimally conscious patients. Data were analyzed using thematic content analysis.

RESULTS

Results suggest that family members and healthcare professionals share similar views of what consciousness is ("being there") and what it is indicated by ("a look in the eyes," and/or an "ability to do"/agency). They also share a belief that the presence (or "level") of consciousness does not determine whether rehabilitative care should be discontinued. Rather, it should be determined by considerations of suffering and well-being. Providers were more likely to view suffering as rationale for discontinuation of care, while family members viewed suffering as an indicator of and motivator for potential recovery.

CONCLUSION

Findings can help optimize family-provider communications about minimally conscious patients by acknowledging shared assumptions and interpretations of consciousness, as well as key areas where perspectives diverge.Implications for rehabilitationFamily and professional caregivers' interpretations of consciousness and suffering are implicated in decisions about continuing rehabilitation for minimally conscious patients.Family members and healthcare providers both rely to some extent on non-observable evidence to evaluate consciousness, which may be an adaptive and philanthropic response to clinical uncertainty.Acknowledging shared assumptions and interpretations of consciousness, as well as diverging perspectives, can help to optimize family-provider communications.

Time-limited trials: A qualitative study exploring the role of time in decision-making on the Intensive Care Unit

Background

Withholding and withdrawing treatment are deemed ethically equivalent by most Bioethicists, but intensivists often find withdrawing more difficult in practice. This can lead to futile treatment being prolonged. Time-limited trials have been proposed as a way of promoting timely treatment withdrawal whilst giving the patient the greatest chance of recovery. Despite being in UK guidelines, time-limited trials have been infrequently implemented on Intensive Care Units. We will explore the role of time in Intensive Care Unit decision-making and provide a UK perspective on debates surrounding time-limited trials.

Methods

This qualitative study recruited 18 participants (nine doctors, nine nurses) from two Intensive Care Units in North West England for in-depth, one-to-one semi-structured interviews. A thematic analysis was performed of the data.

Results

Our findings show time is utilised by Intensive Care Unit staff in a variety of ways including managing uncertainty when making decisions about a patient’s prognosis or the reversibility of a disease, constructing relationships with patients’ relatives, communicating difficult messages to patients’ relatives, justifying resource allocation decisions to colleagues, and demonstrating compassion towards patients and their families.

Conclusions

Time shifts the balance towards greater certainty in Intensive Care Unit decision-making, by demonstrating futility, and can ease the difficult transition for staff and families from active treatment to palliation. However, this requires clear and open communication, both within the Intensive Care Unit team and with the family, being prioritised when time is used in decision-making.

Evaluating ICU Clinical Severity Scoring Systems and Machine Learning Applications: APACHE IV/IVa Case Study

Clinical scoring systems have been developed for many specific applications, yet they remain underutilized for common reasons such as model inaccuracy and difficulty of use. For intensive care units specifically, the Acute Physiology and Chronic Health Evaluation (APACHE) score is used as a decision-making tool and hospital efficacy measure. In an attempt to alleviate the general underlying limitations of scoring instruments and demonstrate the utility of readily available medical databases, machine learning techniques were used to evaluate APACHE IV and IVa prediction measures in an open-source, teleICU research database. The teleICU database allowed for large-scale evaluation of APACHE IV and IVa predictions by comparing predicted values to the actual, recorded patient outcomes along with preliminary exploration of new predictive models for patient mortality and length of stay in both the hospital and the ICU. An increase in performance was observed in the newly developed models trained on the APACHE input variables highlighting avenues of future research and illustrating the utility of teleICU databases for model development and evaluation.

Low Level of Vegetative State After Traumatic Brain Injury in a Swiss Academic Hospital

BACKGROUND

No standards exist regarding decision making for comatose patients, especially concerning life-saving treatments. The aim of this retrospective, single-center study was to analyze outcomes and the decision-making process at the end of life (EOL) in patients with traumatic brain injury (TBI) in a Swiss academic tertiary care hospital.

METHODS

Consecutive admissions to the surgical intensive care unit (ICU) with stays of at least 48 hours between January 1, 2012 and June 30, 2015 in patients with moderate to severe TBI and with fatality within 6 months after trauma were included. Descriptive statistics were used.

RESULTS

Of 994 ICU admissions with TBI in the study period, 182 had an initial Glasgow Coma Scale <13 and a length of stay in the ICU >48 hours. For 174 of them, a 6-month outcome assessment based on the Glasgow Outcome Scale (GOS) was available: 43.1% (36.0%-50.5%) had favorable outcomes (GOS 4 or 5), 28.7% (22.5%-35.9%) a severe disability (GOS 3), 0.6% (0%-3.2%) a vegetative state (GOS 2), and 27.6% (21.5%-34.7%) died (GOS 1). Among the GOS 1 individuals, 45 patients had a complete dataset (73% men; median age, 67 years; interquartile range, 43-79 years). Life-prolonging therapies were limited in 95.6% (85.2%-99.2%) of the cases after interdisciplinary prognostication and involvement of the surrogate decision maker (SDM) to respect the patient's documented or presumed will. In 97.7% (87.9%-99.9%) of the cases, a next of kin was the SDM and was involved in the EOL decision and process in 100% (96.3%-100.0%) of the cases. Written advance directives (ADs) were available for 14.0% (6.6%-27.3%) of the patients, and 34.9% (22.4%-49.8%) of the patients had shared their EOL will with relatives before trauma. In the other cases, each patient's presumed will was acknowledged after a meeting with the SDM and was binding for the EOL decision.

CONCLUSIONS

At our institution, the majority of deaths after TBI follow a decision to limit life-prolonging therapies. The frequency of patients in vegetative state 6 months after TBI is lower than expected; this could be due to the high prevalence of limitation of life-prolonging therapies. EOL decision making follows a standardized process, based on patients' will documented in the ADs or on preferences assumed by the SDM. The prevalence of ADs was low and should be encouraged.

Frailty is associated with adverse outcome from in-hospital cardiopulmonary resuscitation

AIM

To assess whether frailty was associated with cardio-pulmonary resuscitation (CPR) outcome in a UK setting.

METHOD

Retrospective review of prospectively collected data on in-hospital cardio-respiratory arrests between 1/1/17 and 31/12/17. Clinical Frailty Scale (CFS) scores were assigned from notes review, patients with CFS scores ≥6 signified moderate or greater frailty.

RESULTS

There were 179 in-hospital cardiac arrest cases where the CFS could be calculated. The median age on admission was 74 (mean 71, range 27-102), 110 patients were male and 69 female. The initial rhythm was non-shockable in 64% of cases. In 49% of cases return of spontaneous circulation (ROSC) was achieved, 22% of the study population survived to hospital discharge. Moderate or greater frailty was present in 31.3% of patients. Return of spontaneous circulation (ROSC) was achieved in 56.1% of patients with a CFS score of 1-5 and 32.1% with scores 6-9 (p < 0.001). Survival to hospital discharge was also associated with frailty, being seen in 31.7% of CFS 1-5 patients but only in 1.8% of CFS 6-9 patients (p < 0.001). In multivariable analysis adjusting for age, presenting rhythm and admitting specialty the effect of frailty on survival to discharge remained significant (p = 0.044).

CONCLUSION

Patients with moderate or greater frailty as determined by CFS score are unlikely to survive to hospital discharge even if ROSC occurs following CPR. This should be considered when making resuscitation status and ceiling of care decisions in this patient group.

Rethinking our definition of operative success: predicting early mortality after emergency general surgery colon resection

Background

The postoperative outcomes of emergency general surgery patients can be fraught with uncertainty. Although surgical risk calculators exist to predict 30-day mortality, they are often of limited utility in preparing patients and families for immediate perioperative complications. Examination of trends in mortality after emergent colectomy may help inform complex perioperative decision-making. We hypothesized that risk factors could be identified to predict early mortality (before postoperative day 5) to inform operative decisions.

Methods

This analysis was a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program database (2012-2014). Patients were stratified into three groups: early death (postoperative day 0-4), late death (postoperative day 5-30), and those who survived. Multivariable logistic regression was used to explore characteristics associated with early death. Kaplan-Meier models and Cox regression were used to further characterize their impact.

Results

A total of 18 803 patients were analyzed. Overall 30-day mortality was 12.5% (3316); of these, 37.1% (899) were early deaths. The preoperative factors most predictive of early death were septic shock (OR 3.62, p<0.001), ventilator dependence (OR 2.81, p<0.001), and ascites (OR 1.63, p<0.001). Postoperative complications associated with early death included pulmonary embolism (OR 5.78, p<0.001), presence of new-onset or ongoing postoperative septic shock (OR 4.45, p<0.001) and new-onset renal failure (OR 1.89, p<0.001). Patients with both preoperative and postoperative shock had an overall mortality rate of 47% with over half of all deaths occurring in the early period.

Conclusions

Nearly 40% of patients who die after emergent colon resection do so before postoperative day 5. Early mortality is heavily influenced by the presence of both preoperative and new or persistent postoperative septic shock. These results demonstrate important temporal trends of mortality, which may inform perioperative patient and family discussions and complex management decisions.

Healthcare processes of laboratory tests for the prediction of mortality in the intensive care unit: a retrospective study based on electronic healthcare records in the USA

OBJECTIVES

Healthcare process carries important prognostic information for patients, but the healthcare processes of laboratory tests have not yet been investigated for patients in the intensive care unit (ICU). The study aimed to investigate the effect of healthcare processes of laboratory tests on hospital mortality, with the hypothesis that the addition of healthcare processes could improve the discrimination for mortality outcome.

DESIGN

The study included 12 laboratory tests. There were two dimensions for each laboratory test. One was the pathophysiology value; and the other was the healthcare process variables including the clock hour, the number of measurements and the measurement time from ICU admission. Generalised additive model was employed to investigate the effect of continuous variables on mortality. Generalised linear models with and without healthcare process variables were compared for their discrimination power.

SETTING

ICUs in an US-based hospital.

PARTICIPANTS

Adult patients included in the critical care big data Medical Information Mart for Intensive Care.

PRIMARY AND SECONDARY OUTCOME MEASURES

The hospital mortality was the primary outcome.

RESULTS

A total of 52 963 adult patients with complete ICU stay information were included for analysis. The mortality rate was 12.3%. Lower number of tests such as 1-3 times were associated with the lowest mortality for most laboratory tests. However, the hematocrit, glucose and potassium required 6-10 measurements for the first 24 hours to reach the lowest mortality rate. In n of the 12 prediction models involving laboratory tests, the addition of healthcare process variables was associated with significantly increased area under receiver operating characteristics.

CONCLUSIONS

The study showed that healthcare processes of laboratory tests were independently associated with hospital mortality. The addition of healthcare processes to the pathophysiology value could increase the discrimination for mortality outcome.

Doctors' perceptions of how resource limitations relate to futility in end-of-life decision making: a qualitative analysis

OBJECTIVE

To increase knowledge of how doctors perceive futile treatments and scarcity of resources at the end of life. In particular, their perceptions about whether and how resource limitations influence end-of-life decision making. This study builds on previous work that found some doctors include resource limitations in their understanding of the concept of futility.

SETTING

Three tertiary hospitals in metropolitan Brisbane, Australia.

DESIGN

Qualitative study using in-depth, semistructured, face-to-face interviews. Ninety-six doctors were interviewed in 11 medical specialties. Transcripts of the interviews were analysed using thematic analysis.

RESULTS

Doctors' perceptions of whether resource limitations were relevant to their practice varied, and doctors were more comfortable with explicit rather than implicit rationing. Several doctors incorporated resource limitations into their definition of futility. For some, availability of resources was one factor of many in assessing futility, secondary to patient considerations, but a few doctors indicated that the concept of futility concealed rationing. Doctors experienced moral distress due to the resource implications of providing futile treatment and the lack of administrative supports for bedside rationing.

CONCLUSIONS

Doctors' ability to distinguish between futility and rationing would be enhanced through regulatory support for explicit rationing and strategies to support doctors' role in rationing at the bedside. Medical policies should address the distinction between resource limitations and futility to promote legitimacy in end-of-life decision making.

Racial and Ethnic Differences in Limiting Life-Sustaining Treatment in Trauma Patients

Introduction:

Differences in health care between racial and ethnic groups exist. The literature suggests that African Americans and Hispanics prefer more aggressive treatment at the end of life. The aim of this study is to assess racial and ethnic differences in limiting life-sustaining treatment (LLST) after trauma.

Study Design:

We performed a 2-year (2013-2014) retrospective analysis of Trauma Quality Improvement Program database. Patients with age ≥16 and Injury Severity Score (ISS) ≥ 16 were included. Outcome measures were the incidence and the predictors of LLST. Multivariable logistic regression was performed to control for confounding variables.

Results:

A total of 97 024 patients were identified. Mean age was 49 (21) years, 68% were male, 68% were white, and 14% were Hispanic. The overall incidence of LLST was 7.2%. Based on race, LLST was selected as consistent with goals of care more often in white when compared to African American individuals who experience serious traumatic injury (8.0% vs 4.5%; P < .001). Based on ethnicity, LLST was more often selected in non-Hispanics (7.5% vs 5.2%, P < .001) when compared to Hispanics. On regression analysis, the independent predictors of LLST were white race (odds ratio [OR]: 2.7 [1.6–4.4], P = .02), non-Hispanic ethnicity (OR: 1.9 [1.4-4.6]; P = .03), severe head injury (OR: 1.7 [1.1-3.2]; P = .04), and ISS (OR: 3.1 [2.4-5.1]; P < .01).

Conclusions:

Differences exist in selecting LLST between different racial and ethnic groups in severe trauma. African Americans and Hispanics are less likely to select LLST when compared to whites and non-Hispanics. Further studies are required to analyze the factors associated with selecting LLST in African Americans and Hispanics.

Goals of Care: Development and Use of the Serious Veterinary Illness Conversation Guide

Goals of care (GOC) conversations and resulting goal-concordant treatment are the heart of palliative medicine. Despite repeated evidence that GOC conversations offer significant benefit and minimal harm, barriers to widespread and high-quality implementation persist in human medicine. One strategy to overcoming these barriers has been utilization of a structured checklist format for serious illness conversations. The Serious Illness Conversation Guide was developed for human patients and has been modified for use in the veterinary profession. The guide promotes individualized, goal-concordant care planning even when conflict and emotional demands are high.

Ethical dilemmas in clinical practice: a perspective on the results of an electronic survey of veterinary anaesthetists

Medical progress has greatly advanced our ability to manage animals with critical and terminal diseases. We now have the ability to sustain life even in the most dire of circumstances. However, the preservation of life may not be synonymous with providing 'quality of life', and worse, could cause unnecessary suffering. Using the results of an electronic survey, we aim to outline and give examples of ethical dilemmas faced by veterinary anaesthetists dealing with critically ill animals, how the impact of these dilemmas could be mitigated, and what thought processes underlie decision-making in such situations.

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.
