Pharmacologic paralysis and withdrawal of mechanical ventilation at the end of life

The logistics of withdrawing life-sustaining medical treatment in the neonatal intensive care unit

Withdrawal of life sustaining medical treatments is a common mode of death in the neonatal intensive care unit. Shared decision making and communication are crucial steps prior to, during and after a withdrawal of life sustaining medical treatments. Discussion should include the steps to occur during the withdrawal. Physicians should recommend appropriate withdrawal steps based on family goals. Stepwise approach should be taken only if a family requests. Care should continue for the family and staff after the withdrawal and the infant's death.

Addressing Suffering in Infants and Young Children Using the Concept of Suffering Pluralism

Despite the central place of suffering in medical care, suffering in infants and nonverbal children remains poorly defined. There are epistemic problems in the detection and treatment of suffering in infants and normative problems in determining what is in their best interests. A lack of agreement on definitions of infant suffering leads to misunderstanding, mistrust, and even conflict amongst clinicians and parents. It also allows biases around intensive care and disability to (mostly unconsciously) affect medical decision-making on behalf of infants. In this paper, I propose the concept of suffering pluralism, which is a novel multidimensional view of infant suffering based on subjective and objective components. The concept of suffering pluralism is more inclusive of the multiple ways in which infant suffering can occur. It acknowledges and defines a subjective component to infant suffering, while also focusing moral attention on objective well-being by describing it using the language of suffering. This concept allows us to better weigh up subjective and objective components of well-being. It also encourages clarity and consistency in claiming suffering, which is likely to improve communication and reduce conflict in medical decision-making for unwell infants and children. I will end by exploring possible critiques and limitations of this concept.

Sugammadex to Reverse Neuromuscular Blockade Prior to Withdrawal of Life Support

In certain end-of-life scenarios, pharmacologic reversal of neuromuscular blockade may be indicated. However, given the depth of blockade frequently necessitated in the ICU setting, rapid reversal of neuromuscular blockade is generally not feasible with conventional reversal agents such as neostigmine that inhibit acetylcholinesterase. Sugammadex is a novel pharmacologic agent for the reversal of neuromuscular blockade that acts by directly encapsulating steroidal neuromuscular blocking agents and providing effective 1:1 binding of rocuronium or vecuronium. This unique mechanism of action is rapid and allows for complete reversal and recovery of neuromuscular function. We report the use of sugammadex to reverse neuromuscular blockade prior to compassionate extubation in three pediatric patients. Its clinical use in children is reviewed, potential applications in the palliative care arena discussed, and dosing algorithms presented.

Sedation practice and discomfort during withdrawal of mechanical ventilation in critically ill patients at end-of-life: a post-hoc analysis of a multicenter study

PURPOSE

Little is known on the incidence of discomfort during the end-of-life of intensive care unit (ICU) patients and the impact of sedation on such discomfort. The aim of this study was to assess the incidence of discomfort events according to levels of sedation.

METHODS

Post-hoc analysis of an observational prospective multicenter study comparing immediate extubation vs. terminal weaning for end-of-life in ICU patients. Discomforts including gasps, significant bronchial obstruction or high behavioural pain scale score, were prospectively assessed by nurses from mechanical ventilation withdrawal until death. Level of sedation was assessed using the Richmond Agitation-Sedation Scale (RASS) and deep sedation was considered for a RASS - 5. Psychological disorders in family members were assessed up until 12 months after the death.

RESULTS

Among the 450 patients included in the original study, 226 (50%) experienced discomfort after mechanical ventilation withdrawal. Patients with discomfort received lower doses of midazolam and equivalent morphine, and were less likely to have deep sedation than patients without discomfort (59% vs. 79%, p < 0.001). After multivariate logistic regression, extubation (as compared terminal weaning) was the only factor associated with discomfort, whereas deep sedation and administration of vasoactive drugs were two factors independently associated with no discomfort. Long-term evaluation of psychological disorders in family members of dead patients did not differ between those with discomfort and the others.

CONCLUSION

Discomfort was frequent during end-of-life of ICU patients and was mainly associated with extubation and less profound sedation.

Ventilator Withdrawal in Anticipation of Death: The Simulation Lab as an Educational Tool in Palliative Medicine

Simulation is a growing model of education in many medical disciplines. Withdrawal of mechanical ventilation is an important skill set for palliative medicine practitioners who must be facile with a variety of end-of-life scenarios and is well suited to the simulation laboratory. We describe a novel approach using high-fidelity simulation to design a curriculum to teach Hospice & Palliative Medicine fellows the practical aspects of managing a compassionate terminal extubation. This simulation session aims to equip palliative fellows with a knowledge base of respiratory physiology and mechanical ventilation as well as the practical experience of performing a terminal extubation. We designed a three-hour simulation session which includes a one-hour didactic followed by two hours of simulation, with four cases that focus on different teaching points regarding symptom management and practical aspects of removing the endotracheal tube. The session was designed as an annual session for Hospice & Palliative Medicine fellows in our region during a collaborative educational conference. Based on feedback, the session is scheduled for the beginning of the academic year and each fellow is given the opportunity to physically remove the endotracheal tube. Simulation can be effectively used to teach practical and complex bedside skills such as withdrawal of mechanical ventilation to palliative medicine trainees. This method of teaching could be expanded to teach other advanced hospice and palliative care skills.

Euthanasia and the Administration of Neuromuscular Blockers without Ventilation: Should Physicians Fear Prosecution?

A common dilemma among physicians who treat the dying is whether pharmacological paralysis should be reversed prior to removal of mechanical ventilation. But what if a physician were to administer a neuromuscular blocker without ever ventilating the patient in the first place? While there is evidence that euthanasia does occur in the United States, few physicians have been prosecuted. Could these infrequent prosecutions reflect a conscious desire by prosecutors not to pursue such matters? In an effort to explore this question, chief prosecutors in four U.S. states were presented with a vignette based on an actual event involving the administration of Succinylcholine to a dying patient. Response rates in this study were very acceptable (76.36% overall), and results indicated that not only was the likelihood of criminal prosecution low, almost half of the prosecutors believed that a physicianadministered lethal injection may be morally justified in some circumstances even though illegal.

Dutch neonatologists have adopted a more interventionist approach to neonatal care

AIM

This study investigated whether continuous improvements to neonatal care and the legalisation of newborn euthanasia in 2005 had changed end-of-life decisions by Dutch neonatologists.

METHODS

We carried out a retrospective study of foetuses and neonates of more than 22 weeks' gestation that died in the delivery room or in the neonatal intensive care unit (NICU) of a tertiary referral hospital in the Netherlands, comparing end-of-life decisions and mortality in 2001-2003 and 2008-2010, before and after euthanasia legislation was introduced.

RESULTS

In 2008-2010, there were more deaths in the delivery room due to termination of pregnancy than in 2001-2003 (17% versus 29%, p = 0.031), and fewer infants received comfort medication (12% versus 20%, p = 0.078). The main mode of death in the NICU was the withdrawal of life-sustaining therapy. The number of days that infants lived increased significantly between 2001-2003 (11.5 days) and 2008-2010 (18.4 days, p < 0.006). Most infants received comfort medication, and neuromuscular blocking agents were administered incidentally.

CONCLUSION

Terminations increased after changes in healthcare regulations. Modes of death in the NICU remained similar over 10 years. The increased duration of NICU treatment before dying suggests a more interventionist approach to treatment in 2008-2010.

Compassionate extubation for a peaceful death in the setting of a community hospital: a case-series study

BACKGROUND

The use of compassionate extubation (CE) to alleviate suffering by terminating mechanical ventilation and withdrawing the endotracheal tube requires professional adherence and efficiency. The Hospice Palliative Care Act, amended on January 9, 2013, legalizes the CE procedure in Taiwan.

METHODS

From September 20, 2013 to September 2, 2014, the hospice palliative care team at a community hospital received 20 consultations for CE. Eight cases were excluded because of non-qualification. Following approval from the Ethics Committee, the medical records of the remaining 12 patients were reviewed and grouped by the underlying disease: A, "terminal-stage cancer"; B, "non-cancer out-of-hospital cardiac arrest"; and C, "non-cancer organ failure". Time to extubation using a cut-off at 48 hours was assessed.

RESULTS

The mean ages of patients (standard deviation) in groups A, B, and C were 66.3 (14.9) years, 72 (19.1) years, and 80.3 (4.0) years, respectively. The mean number of days of intubation at consultation were 6.8 (4.9), 7.3 (4.9), and 179.3 (271.6), respectively. The mean total doses of opioids (as morphine-equivalent dose) in the 24 hours preceding CE were 76 (87.5) mg, 3.3 (5.8) mg, and 43.3 (15.3) mg. The median times from extubation (range) to death were 97 (0.2-245) hours, 0.3 (0.2-0.4) hours, and 6.1 (3.6-71.8) hours. Compared to those requiring <48-hour preparatory time, patients requiring >48 hours to the moment of CE were younger (62.8 years vs 75.5 years), required a mean time of 122 hours (vs 30 hours) to CE (P=0.004), had shorter length of stay (33.3 days vs 77.8 days), required specialist social worker intervention in 75% of cases (vs 37.5%), and had a median duration of intubation of 11.5 days (vs 5.5 days).

CONCLUSION

CE was carried out according to protocol, and the median time from extubation to death varies determined by the underlying disease which was 0.3 hour in patients admitted after out-of-hospital cardiac arrest and 97 hours in patients with advanced cancer.

Infants' best interests in end-of-life care for newborns

BACKGROUND AND OBJECTIVES

Pediatric bioethics presumes that decisions should be taken in the child's best interest. If it's ambiguous whether a decision is in the child's interest, we defer to parents. Should parents be permitted to consider their own interests in making decisions for their child? In the Netherlands, where neonatal euthanasia is legal, such questions sometimes arise in deciding whether to hasten the death of a critically ill, suffering child. We describe the recommendations of a national Dutch committee. Our objectives were to analyze the role of competing child and family interests and to provide guidance on end-of-life decisions for doctors caring for severely ill newborns.

METHODS

We undertook literature review, 7 consensus meetings in a multidisciplinary expert commission, and invited comments on draft report by specialists' associations.

RESULTS

Initial treatment is mandatory for most ill newborns, to clarify the prognosis. Continuation of treatment is conditional on further diagnostic and prognostic data. Muscle relaxants can sometimes be continued after withdrawal of artificial respiration without aiming to shorten the child's life. When gasping causes suffering, or protracted dying is unbearable for the parents, muscle relaxants may be used to end a newborn's life. Whenever muscle relaxants are used, cases should be reported to the national review committee.

CONCLUSIONS

New national recommendations in the Netherlands for end-of-life decisions in newborns suggest that treatment should generally be seen as conditional. If treatment fails, it should be abandoned. In those cases, palliative care should be directed at both infant and parental suffering. Sometimes, this may permit interventions that hasten death.

Ethical reflections on end-of-life signs and symptoms in the intensive care setting: a place for neuromuscular blockers?

The death of a loved one is often an ordeal and a tragedy for those who witness it, as death is not merely the end of a life, but also the end of an existence, the loss of a unique individual who is special and irreplaceable. In some situations, end-of-life signs, such as agonal gasps, can be an almost unbearable "sight" because the physical manifestations are hard to watch and can lead to subjective interpretation and irrational fears. Ethical unease arises as the dying patient falls prey to death throes and to the manifestations of ebbing life and the physician can only stand by and watch. From this point on, medicine can put an end to suffering by the use of neuromuscular blockade, but in so doing life ceases at the same time. It is difficult, however, not to respond to the distress of loved ones and caregivers. The ethical problem then becomes the shift from the original ethical concern, i.e. the dying patient, to the patient's loved ones. Is such a rupture due to a difference in nature or a difference in degree, given that the dying patient remains a person and not a thing as long as the body continues to lead its own life, expressed through movement and sound? Because there cannot be any simple and unequivocal answer to this question, the SRLF Ethics Commission is offering ethical reflections on end-of-life signs and symptoms in the intensive care setting, and on the use of neuromuscular blockade in this context, with presentations on the subject by two philosophers and members of the SRLF Ethics Commission, Ms Lise Haddad and Prof Dominique Folscheid. The SRLF Ethics Commission hopes to provide food for thought for everyone on this topic, which undoubtedly calls for further contributions, the aim being not to provide ready-made solutions or policy, but rather to allow everyone to ponder this question in all conscience.

Survey of neonatologists' attitudes toward limiting life-sustaining treatments in the neonatal intensive care unit

OBJECTIVE

To understand neonatologists' attitudes toward end-of-life (EOL) management in clinical scenarios, EOL ethical concepts and resource utilization.

STUDY DESIGN

American Academy of Pediatrics (AAP) Perinatal section members completed an anonymous online survey. Respondents indicated preferences in limiting life-sustaining treatments in four clinical scenarios, ranked agreement with EOL-care ethics statements, indicated outside resources previously used and provided demographic information.

RESULT

In all, 451 surveys were analyzed. Across clinical scenarios and as general ethical concepts, withdrawal of mechanical ventilation in severely affected patients was most accepted by respondents; withdrawal of artificial nutrition and hydration was least accepted. One-third of neonatologists did not agree that non-initiation of treatment is ethically equivalent to withdrawal. Around 20% of neonatologists would not defer care if uncomfortable with a parent's request. Respondents' resources included ethics committees, AAP guidelines and legal counsel/courts.

CONCLUSION

Challenges to providing just, unified EOL care strategies are discussed, including deferring care, limiting artificial nutrition/hydration and conditions surrounding ventilator withdrawal.

Unnecessary time pressure in refusal of life-sustaining therapies: fear of missing the opportunity to die

During an illness requiring brief use of life-sustaining therapy (LST), patients and surrogates sometimes feel that LST must be withdrawn before it becomes unnecessary to avoid later being stuck living in a debilitated condition that the patient considers worse than death. This fear depends on the belief that the patient can legitimately refuse only artificial LST, so that if such therapies are no longer required, he or she will have missed the 'opportunity to die.' This fear of being stuck with life can lead to premature decisions to terminate LST and is unfounded because adequate ethical and moral justification exists for refusal of not just artificial LST, but also for refusal of natural LST, including oral hydration and nutrition.

Forgoing life-sustaining or death-prolonging therapy in the pediatric ICU

Most deaths in the pediatric intensive care unit occur after a decision to withhold or withdraw life-sustaining treatments. The management of children at the end of life can be divided into three steps. The first concerns the decision-making process. The second concerns the actions taken once a decision has been made to forego life-sustaining treatments. The third regards the evaluation of the decision and its implementation. The mission of pediatric intensive care has expanded to provide the best possible care to dying children and their families. Improving the quality of care received by dying children remains an ongoing challenge for every pediatric intensive care unit team member.

Recommendations for end-of-life care in the intensive care unit: a consensus statement by the American College [corrected] of Critical Care Medicine

BACKGROUND

These recommendations have been developed to improve the care of intensive care unit (ICU) patients during the dying process. The recommendations build on those published in 2003 and highlight recent developments in the field from a U.S. perspective. They do not use an evidence grading system because most of the recommendations are based on ethical and legal principles that are not derived from empirically based evidence.

PRINCIPAL FINDINGS

Family-centered care, which emphasizes the importance of the social structure within which patients are embedded, has emerged as a comprehensive ideal for managing end-of-life care in the ICU. ICU clinicians should be competent in all aspects of this care, including the practical and ethical aspects of withdrawing different modalities of life-sustaining treatment and the use of sedatives, analgesics, and nonpharmacologic approaches to easing the suffering of the dying process. Several key ethical concepts play a foundational role in guiding end-of-life care, including the distinctions between withholding and withdrawing treatments, between actions of killing and allowing to die, and between consequences that are intended vs. those that are merely foreseen (the doctrine of double effect). Improved communication with the family has been shown to improve patient care and family outcomes. Other knowledge unique to end-of-life care includes principles for notifying families of a patient's death and compassionate approaches to discussing options for organ donation. End-of-life care continues even after the death of the patient, and ICUs should consider developing comprehensive bereavement programs to support both families and the needs of the clinical staff. Finally, a comprehensive agenda for improving end-of-life care in the ICU has been developed to guide research, quality improvement efforts, and educational curricula.

CONCLUSIONS

End-of-life care is emerging as a comprehensive area of expertise in the ICU and demands the same high level of knowledge and competence as all other areas of ICU practice.

Withdrawal of mechanical ventilation in pediatric and neonatal intensive care units

Withdrawing life-sustaining technologies requires all of the resources and concepts that the field of palliative care has to offer. By learning some fundamental principles of medical management at the time of withdrawal and by mastering a few communication techniques, pediatricians, neonatologists, and pediatric intensivists can dramatically improve the care provided to their patients at the end of life. Although we may argue in pediatrics if there is ever such a thing as a good death, we should all strive to ensure one that is free of suffering, and one that supports the family in moving down a path of healthy grief and recovery.

Physician medical decision-making at the end of life in newborns: insight into implementation at 2 Dutch centers

OBJECTIVE

Decisions regarding end-of-life care in critically ill newborns in The Netherlands have received considerable criticism from the media and from the public. This might be because of a lack of proper information and knowledge. Our purpose was to provide detailed information about how and when the implementation of end-of-life decisions, which are based on quality-of-life considerations, takes place.

METHODS

We reviewed the charts of all infants who died within the first 2 months of life at 2 university hospitals in The Netherlands from January to July 2005 and extracted all relevant information about the end-of-life decisions. We interviewed the responsible neonatologists about the end-of-life decisions and the underlying quality-of-life considerations and about the process of implementation.

RESULTS

Of a total of 30 deaths, 28 were attributable to withholding or withdrawing life-sustaining treatment. In 18 of 28 cases, the infant had no chance to survive; in 10 cases, the final decision was based on the poor prognosis of the infant. In 6 patients, 2 successive different end-of-life decisions were made. The arguments that most frequently were used to conclude that quality of life was deemed poor were predicted suffering and predicted inability of verbal and nonverbal communication. Implementation consisted of discontinuation of ventilatory support and alleviation of pain and symptoms. Neuromuscular blockers were added shortly before death in 5 cases to prevent gasping, mostly on parental request.

CONCLUSIONS

The majority of deaths were attributable to withholding or withdrawing treatment. In most cases, the newborn had no chance to survive and prolonging of treatment could not be justified. In the remaining cases, withholding or withdrawing treatment was based on quality-of-life considerations, mostly the predicted suffering and predicted inability of verbal and nonverbal communication. Potentially life-shortening medication played a minor role as a cause of death.

Death in the pediatric ICU: caring for children and families at the end of life

The need to improve care for children and families at the end of life is acknowledged widely. This article reviews current research concerning end-of-life care in the pediatric ICU. How children die, how decisions are made, management of the dying process, and parent and caregiver experiences are major themes. Gaps in current knowledge are identified, and suggestions are made for future research.

Interventions to Improve Care during Withdrawal of Life-Sustaining Treatments

Withdrawal of life-sustaining therapies is a common occurrence in the intensive care unit (ICU) setting and also occurs in other hospital settings, long-term care facilities, and even at home. Many studies have documented dramatic geographic variations in the prevalence of withdrawal of life-sustaining therapies, and some evidence suggests this variation may be driven more by physician attitudes and biases than by factors such as patient preferences or cultural differences. A number of studies of interventions in the ICU setting have provided some evidence that withdrawal of life-sustaining therapies is a process of care that can be improved. The interventions have included routine ethics or palliative care consultations, routine family conferences, and standardized order protocol for withdrawal of life support. For some of the interventions, for example, ethics consultations or palliative care consultations, the precise mechanisms by which the process of care is improved are not clear. Furthermore, many of these studies have used surrogate outcomes for quality, such as ICU length of stay. Emerging research suggests more direct outcome measures may be useful, including family satisfaction with care and assessments of the quality of dying. Despite these relative limitations, these studies provide convincing evidence that withdrawal of life-sustaining therapy is a process of care that presents opportunities for quality improvement and that interventions are successful at improving this care. Further research is needed to identify and test the most appropriate and responsive outcome measures and to identify the most effective and cost-effective interventions.

New and lingering controversies in pediatric end-of-life care

OBJECTIVES

Professional societies, ethics institutes, and the courts have recommended principles to guide the care of children with life-threatening conditions; however, little is known about the degree to which pediatric care providers are aware of or in agreement with these guidelines. The study's objectives were to determine the extent to which physicians and nurses in critical care, hematology/oncology, and other subspecialties are in agreement with one another and with widely published ethical recommendations regarding the withholding and withdrawing of life support, the provision of adequate analgesia, and the role of parents in end-of-life decision-making.

METHODS

Three children's hospitals and 4 general hospitals with PICUs in eastern, southwestern, and southern parts of the United States were surveyed. This population-based sample was composed of attending physicians, house officers, and nurses who cared for children (age: 1 month to 18 years) with life-threatening conditions in PICUs or in medical, surgical, or hematology/oncology units, floors, or departments. Main outcome measures included concerns of conscience, knowledge and beliefs, awareness of published guidelines, and agreement or disagreement with guidelines.

RESULTS

A total of 781 clinicians were sampled, including 209 attending physicians, 116 house officers, and 456 nurses. The overall response rate was 64%. Fifty-four percent of house officers and substantial proportions of attending physicians and nurses reported, "At times, I have acted against my conscience in providing treatment to children in my care." For example, 38% of critical care attending physicians and 25% of hematology/oncology attending physicians expressed these concerns, whereas 48% of critical care nurses and 38% of hematology/oncology nurses did so. Across specialties, approximately 20 times as many nurses, 15 times as many house officers, and 10 times as many attending physicians agreed with the statement, "Sometimes I feel we are saving children who should not be saved," as agreed with the statement, "Sometimes I feel we give up on children too soon." However, hematology/oncology attending physicians (31%) were less likely than critical care (56%) and other subspecialty (66%) attending physicians to report, "Sometimes I feel the treatments I offer children are overly burdensome." Many respondents held views that diverged widely from published recommendations. Despite a lack of awareness of key guidelines, across subspecialties the vast majority of attending physicians (range: 92-98%, depending on specialty) and nurses (range: 83-85%) rated themselves as somewhat to very knowledgeable regarding ethical issues.

CONCLUSIONS

There is a need for more hospital-based ethics education and more interdisciplinary and cross-subspecialty discussion of inherently complex and stressful pediatric end-of-life cases. Education should focus on establishing appropriate goals of care, as well as on pain management, medically supplied nutrition and hydration, and the appropriate use of paralytic agents. More research is needed on clinicians' regard for the dead-donor rule.

Cuidados al final de la vida en la unidad de cuidados intensivos pediátrica. Revisión de la bibliografía

INTRODUCTION

In the last few years, there has been growing concern in the literature about issues related to end-of-life care in pediatric intensive care units (PICUs), with special attention on the family/patient unit, communication, and a dignified death.

OBJECTIVE

To evaluate the experience and development of end-of-life care in PICUs through a literature review, by determining the type of studies that have been performed, their topics, the issues discussed, and their development in the last few years.

MATERIAL AND METHODS

Review of the medical literature in Medline and the database of the National Library of Medicine Gateway, using the key words from MeSH: "end of life", "pediatric intensive care", "critical care", "palliative care", "death", and "compassionate care". The earliest year of the search was 1990. The languages selected were English and Spanish. Inclusion criteria were the relationship with the topic to be studied, excluding articles with no abstract. Additional searches were made of references in selected articles.

RESULTS

Eighty-one articles were retrieved from the initial search. Of these, 43 were selected as the most relevant investigations in end-of-life care in ICUs and 18 placed special emphasis on the PICU. More than half of the articles (62 %) were reviews and the remaining articles were descriptive or observational studies. The number of publications increased after 1995. Most of the studies were performed in the USA or Canada and only three studies were performed in Spain.

CONCLUSIONS

In the last few years, several studies have been performed that reveal increasing concern about limits to therapeutic intervention and the need to improve end-of-life care in the PICU setting.

End-of-life care in the pediatric intensive care unit: research review and recommendations

Improving the quality of end-of-life care has become a national health care priority. A necessary step in this process in the pediatric intensive care unit (ICU) is examining the knowledge, attitudes,and behaviors of pediatric critical care practitioners in this area. In addition, the perspectives of bereaved parents must be uncovered as well. In this article, the empirical data in the literature on end-of-life care in the pediatric ICU are reviewed, common ethical controversies in this environment are discussed, and promising interventions for the future are presented.

Principles and practice of withdrawing life-sustaining treatments

The clinician's responsibility to the patient does not end with a decision to limit medical treatment, but continues through the dying process. Every effort should be made to ensure that withdrawing life support occurs with the same quality and attention to detail as is routinely provided when life support is initiated. Approaching the withdrawal of life support as a medical procedure provides clinicians with a recognizable framework for their actions. Key steps in this process are identifying and communicating explicit shared goals for the process, approaching withdrawal of life-sustaining treatments asa medical procedure, and preparing protocols and materials to assure consistent care. Our hope is that adopting a more formal approach to this common procedure will improve the care of patients dying in intensive care units.

A descriptive study of children dying in the pediatric intensive care unit after withdrawal of life-sustaining treatment

OBJECTIVE

To examine physiologic and therapeutic changes following withdrawal of life-sustaining treatment in children.

DESIGN

Retrospective chart review.

SETTING

University-affiliated tertiary care pediatric hospital.

PATIENTS

All patients who had life-sustaining treatment withdrawn over a 5-yr period.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

A total of 125 charts were examined to obtain 50 in which the terminal event preceding death was withdrawal of life-sustaining treatment. Data are expressed as median (1st, 3rd quartiles). Median hospital stay before death was 20 days (1st and 3rd quartiles, 8 and 30). Median time from decision to withdraw life-sustaining treatment to actual withdrawal was 30 mins (1st and 3rd quartiles, 10 and 180). All interventions were simultaneously discontinued in 80% of patients with mechanical ventilation followed by vasopressors being most common. No patients had stepwise reduction in ventilator rate before discontinuing the mechanical ventilation. Devices were rarely removed from patients including endotracheal tubes. Time from withdrawal of life-sustaining treatment to death was 15 mins (5, 30); only seven patients took >60 mins to die. Multivariable analysis (Kruskal-Wallis test) of various factors revealed simultaneous withdrawal of life-sustaining treatment, female gender, and not having received renal therapy as hastening death.

CONCLUSIONS

Forgoing life-sustaining treatment in a small cohort of children at a single institution follows a pattern: Most cases occur after prolonged intensive care unit stays, withdrawal of treatment occurs almost immediately after the decision to withdraw, most treatments are withdrawn simultaneously rather than sequentially, and most patients die within minutes of life-sustaining treatment cessation. This is the first pediatric study to report the time to death after withdrawal of life-sustaining treatment and factors associated with shorter time to death in children.

Relationship between conflicts of interest and research results

CONTEXT

To date, research regarding the influence of conflicts of interest on the presentation of findings by researchers has been limited.

OBJECTIVE

To evaluate the sources of funding for published manuscripts, and association between reported findings and conflicts of interest.

METHODS

Data from both print and electronic issues of The New England Journal of Medicine (NEJM) and The Journal of the American Medical Association (JAMA) were analyzed for sources of funding, areas of investigation, conflict of interest (COI), and presentation of results. We reviewed all original manuscripts published during the year 2001 within NEJM (N = 193) and JAMA (N = 205). We use 3 definitions for COI in this paper: a broadly defined criterion, the criterion used by The International Council of Medical Journal Editors (ICMJE), and a criterion defined by the authors.

RESULTS

Depending on the COI criteria used, 16.6% to 32.6% of manuscripts had 1 or more author with COI. Based on ICMJE criterion, 38.7% of studies investigating drug treatments had authors with COI. We observed a strong association between those studies whose authors had COI and reported positive findings (P <.001). When controlling for sample size, study design, and country of primary authors, we observed a strong association between positive results and COI (ICMJE definition) among all treatment studies (adjusted odds ratio [OR], 2.35; 95% confidence interval [CI], 1.08 to 5.09) and drug studies alone (OR, 2.64; 95% CI, 1.09 to 6.39).

CONCLUSION

COI is widespread among the authors of published manuscripts and these authors are more likely to present positive findings.

Circumstances surrounding end of life in a pediatric intensive care unit

OBJECTIVE

Approximately 60% of deaths in pediatric intensive care units follow limitation or withdrawal of life-sustaining treatment (LST). We aimed to describe the circumstances surrounding decision making and end-of-life care in this setting.

METHODS

We conducted a prospective, descriptive study based on a survey with the intensivist after every consecutive death during an 8-month period in a single multidisciplinary pediatric intensive care unit. Summary statistics are presented as percentage, mean +/- standard deviation, or median and range; data are compared using the Mantel-Haenszel test and shown as survival curves.

RESULTS

Of the 99 observed deaths, 27 involved failed cardiopulmonary resuscitation; of the remaining 72, 39 followed withdrawal/limitation (W/LT) of LST, 20 were do not resuscitate (DNR), and 13 were brain deaths (BDs). Families initiated discussions about forgoing LST in 24% (17 of 72) of cases. Consensus between caregivers and staff about forgoing LST as the best approach was reached after the first meeting with 51% (35 of 68) of families; 46% (31 of 68) required >or=2 meetings (4 not reported). In the DNR group, the median time to death after consensus was 24 hours and for W/LT was 3 hours. LST was later withdrawn in 11 of 20 DNR cases. The family was present in 76% (45 of 59) of cases when LST was forgone. The dying patient was held by the family in 78% (35 of 45) of these occasions.

CONCLUSIONS

More than 1 formal meeting was required to reach consensus with families about forgoing LST in almost half of the patients. Families often held their child at the time of death. The majority of children died quickly after the end-of-life decision was made.

Terminally ill patients and Jehovah's Witnesses: teaching acceptance of patients' refusals of vital treatments

OBJECTIVES

To find out whether and how the teaching of medical ethics can influence attitudes on accepting treatment refusals.

SETTING AND DESIGN

Anonymous questionnaires were distributed to 4 groups of students at the University of Geneva who had participated (P) or not (nP) in teaching modules on medical law and ethics. One vignette described a terminally ill patient refusing mechanical ventilation, another a Jehovah's Witness refusing a life-saving blood transfusion.

PARTICIPANTS

127 medical and 168 law students.

MAIN OUTCOME MEASURES

5-point Likert scale of responses to the vignettes reaching from certain acceptance to certain non-acceptance of the treatment refusal.

RESULTS

More than 80% of law students (nP) said that a good physician should accept the terminally ill patient's refusal. 84% (P) compared to 68% (nP) of medical students (P=0.03) would accept this refusal. The acceptance of the Jehovah's Witness refusal of a life-saving transfusion was less among all students. Students from the groups (P) reported significantly more often (P < 0.001) that they would accept (76% of medical students) or that a good physician should accept (63% of law students) the treatment refusal of the Jehovah's Witness than medical students (48%) and law students (27%) from the two other groups (nP).

CONCLUSION

(P) students showed significantly more acceptance of treatment refusals in the hypothetical case scenarios than (nP) students from the same faculty. Religion, cultural origin and school education of the parents had less influence on attitudes than participation in ethical teaching and type of student (medicine vs. law).

Ethical and legal issues in palliative care

This article reviews the ethical principles underlying palliative care, stressing the importance of respecting patient's rights to withdraw or withhold life-sustaining treatment, including artificial hydration and nutrition. There is no ethical or constitutional right to receive physician-assisted suicide or voluntary active euthanasia. This article discusses current ethical controversies in palliative care, including futility, medication dosage and double-effect, terminal sedation, legalization of physician-assisted suicide and euthanasia, and patient refusal of hydration and nutrition. Relevant legal issues are discussed in tandem with the ethical issues.

End-of-life care for neonates and infants: the experience and effects of a palliative care consultation service

OBJECTIVE

Neonates and infants have the highest death rate in the pediatric population, yet there is a paucity of data about their end-of-life care and whether a palliative care service can have an impact on that care. The objective of this study was to describe end-of-life care for infants, including analysis of palliative care consultations conducted in this population. We hypothesized that the palliative care consultations performed had an impact on the infants' end-of-life care.

DESIGN

A retrospective chart review using the "End of Life Chart Review" from the Center to Improve Care for the Dying was conducted. The participants were the patients at Children's Hospital of Wisconsin who died at <1 year of age during the 4-year period between January 1, 1994, and December 31, 1997. The patients' place of death, medical interventions performed, and emotionally supportive services provided to families were analyzed.

RESULTS

Among the 196 deaths during the study period, 25 (13%) of these infants and families had palliative care consultations. The rate of consultations increased from 5% of the infant deaths in 1994 to 38% of the infant deaths in 1997. Infants of families that received consultations had fewer days in intensive care units, blood draws, central lines, feeding tubes, vasopressor and paralytic drug use, mechanical ventilation, cardiopulmonary resuscitation, and x-rays, and the families had more frequent referrals for chaplains and social services than families that did not have palliative care consultations.

CONCLUSIONS

This study describes the end-of-life care that infants and their families received. Fewer medical procedures were performed, and more supportive services were provided to infants and families that had a palliative care consultation. This suggests that palliative care consultation may enhance end-of-life care for newborns.

Biomedical ethics and the withdrawal of advanced life support

It is common for health care providers to deal with the complex and difficult issue of withdrawing advanced life support. The patient is always the key source of authority in these decisions. The most important ingredient in end-of-life decision making is effective communication. It is important to try to ascertain what the patient thought about quality-of-life values before surrogate decisions can be made on the patient's behalf. The concepts of beneficence, nonmaleficence, autonomy, and justice are the foundation of ethical decision making. Numerous legal precedents have laid the groundwork for end-of-life decision making. Most state courts have supported withholding and withdrawing life support from patients who will not regain a reasonable quality of life. The recent Patient Self-Determination Act encourages patients to fill out advance directives that state their desires. When continued intensive care is futile, advanced life support should be withdrawn. However, a narrow definition of futility in this situation is the key, since the concept of futility could lead to inappropriate decisions. It is best to consider a situation futile when the patient is terminally ill, the condition is irreversible, and death is imminent. During the withdrawal of advanced life support, terminal or rapid weaning is preferable to extubation. Combinations of opiates, benzodiazepines, and other agents help provide comfort to patients who are suffering.

End-of-life care in the pediatric intensive care unit: Attitudes and practices of pediatric critical care physicians and nurses

OBJECTIVE

To determine the attitudes and practices of pediatric critical care attending physicians and pediatric critical care nurses on end-of-life care.

DESIGN

Cross-sectional survey.

SETTING

A random sample of clinicians at 31 pediatric hospitals in the United States.

MEASUREMENTS AND MAIN RESULTS

The survey was completed by 110/130 (85%) physicians and 92/130 (71%) nurses. The statement that withholding and withdrawing life support is unethical was not endorsed by any of the physicians or nurses. More physicians (78%) than nurses (57%) agreed or strongly agreed that withholding and withdrawing are ethically the same (p < .001). Physicians were more likely than nurses to report that families are well informed about the advantages and limitations of further therapy (99% vs. 89%; p < .003); that ethical issues are discussed well within the team (92% vs. 59%; p < .0003), and that ethical issues are discussed well with the family (91% vs. 79%; p < .0002). On multivariable analyses, fewer years of practice in pediatric critical care was the only clinician characteristic associated with attitudes on end-of-life care dissimilar to the consensus positions reached by national medical and nursing organizations on these issues. There was no association between clinician characteristics such as their political or religious affiliation, practice-related variables such as the size of their intensive care unit or the presence of residents and fellows, and particular attitudes about end-of-life care.

CONCLUSIONS

Nearly two-thirds of pediatric critical care physicians and nurses express views on end-of-life care in strong agreement with consensus positions on these issues adopted by national professional organizations. Clinicians with fewer years of pediatric critical care practice are less likely to agree with this consensus. Compared with physicians, nurses are significantly less likely to agree that families are well informed and ethical issues are well discussed when assessing actual practice in their intensive care unit. More collaborative education and regular case review on bioethical issues are needed as part of standard practice in the intensive care unit.

End-of-life care: what do the American courts say?

End-of-life care of critically ill patients generally consists of two closely related practices: the withholding and withdrawal of life support, and the administration of palliative care. In the United States, the withholding or withdrawal of life support is legally justified by the principles of informed consent and informed refusal. The U.S. Supreme Court has held that competent patients may refuse any and all treatments, including those that sustain life. All states sanction such refusal by competent patients, and most states allow surrogates to refuse treatment on behalf of incompetent patients. Although some physicians use the concept of futility to unilaterally withhold or withdraw life support, the Supreme Court has not heard a futility case, and the only clear legal rule on futile treatment is the traditional malpractice test, which measures physician actions against standards of medical care. However, the Supreme Court has furnished guidelines on the administration of palliative care. By using the principle of double effect, these guidelines allow physicians to give sedative and analgesic agents to dying patients if they intend to relieve pain and suffering but not to hasten death.

End-of-life care in the intensive care unit: where are we now?

A growing body of evidence and experience has effaced what were once thought to be clear distinctions between "critical illness" and "terminal illness" and has exposed the problems of postponing palliative care for intensive care patients until death is obviously imminent. Integration of palliative care as a component of comprehensive intensive care is now seen as more appropriate for all critically ill patients, including those pursuing aggressive treatments to prolong life. At present, however, data on which to base practice in this integrated model remain insufficient, and forces of the healthcare economy and other factors may constrain its application. The purpose of this article is to map where we are now in seeking to improve palliative care in the intensive care unit. We review existing evidence, which suggests that both symptom management and communication about preferences and goals of care warrant improvement and that prevailing practices for limitation of life-sustaining treatments are inconsistent and possibly irrational. We also address the need for assessment tools for research and quality improvement. We discuss recent initiatives and ongoing obstacles. Finally, we identify areas for further exploration and suggest guiding principles.
