Modes of death in the pediatric intensive care unit: withdrawal and limitation of supportive care

Communicating about end-of-life care with patients and families in the intensive care unit

Discussing end-of-life care and death with patients and their families is an extremely important part of providing a good quality care in the intensive care unit (ICU). Although there is little empiric research to guide ICU clinicians in the most effective way to have these conversations, there is a developing literature and experience and an increasing emphasis on making this an important part of the care we provide. Much like other ICU procedures or skills,providing sensitive and effective communication about end-of-life care requires training, practice, and supervision, as well as planning and preparation. Although different clinicians may have different approaches and should change their approach to match the needs of individual patients and their families, this article reviews some of the fundamental components to discussing end-of-life care in the ICU that should be part of the care of patients with life-threatening illnesses in the ICU.

Evaluation of a standardized order form for the withdrawal of life support in the intensive care unit

OBJECTIVE

The intensive care unit remains a setting where death is common, and a large proportion of these deaths are preceded by withdrawal of life support. We describe a quality improvement project implementing and evaluating a "withdrawal of life support order form" to improve quality of end-of-life care in the intensive care unit.

DESIGN

Before-after evaluation.

SETTING

County-owned, university-operated, tertiary, level I trauma center.

SUBJECTS

Subjects were 143 nurses and 61 physicians.

INTERVENTIONS

We conducted a before-after evaluation of the order form's implementation. The order form has sections on preparations, sedation/analgesia, withdrawal of mechanical ventilation, and the principles of life support withdrawal. To evaluate the form, we surveyed intensive care unit clinicians regarding satisfaction with the form, measured nurse-assessed quality of dying and death with a 14-item survey (scored 0 for worst possible death to 100 for best possible), and performed chart review to assess narcotic and benzodiazepine use and time from ventilator withdrawal to death.

MEASUREMENTS AND MAIN RESULTS

We surveyed 143 nurses and 61 physicians about satisfaction with the form. Among nurses reporting that the form was used (n = 73), most (84%) reported that the order form was helpful and they were most satisfied with the sedation and mechanical ventilation sections. Almost all physicians found the form helpful (95%), and > 70% of physicians found three of the four sections helpful (sedation, mechanical ventilation, and preparations). We obtained quality of dying and death scores for 41 patient deaths before and 76 deaths after the intervention. These scores did not significantly change (mean preintervention score, 78.3; mean postintervention score, 74.2; p = .54) before and after the intervention. Total doses of narcotics and benzodiazepines increased after implementation of the order form in the hour before ventilator withdrawal, the hour after ventilator withdrawal, and the hour before death (p < or = .03). There was no change in the median time from ventilator withdrawal to death (preintervention 37 mins, postintervention 39 mins; p = .49).

CONCLUSIONS

Nurses and physicians found the withdrawal of life support order form helpful. The order form did not improve nurses' assessment of patients' dying experience. Medications for sedation increased during the postorder form period without evidence of significantly hastening death. Although the order form was helpful to clinicians and changed medication delivery, demonstrating clear improvements in quality of dying may require larger sample sizes, more sensitive measures, or more effective interventions.

Forgoing life-sustaining treatments in children: a comparison between Northern and Southern European pediatric intensive care units

OBJECTIVES

This study was conducted to determine how the decision-making process to forgo life support differs between southern and northern European pediatric intensive care units.

DESIGN

Multiple-center, prospective study.

SETTING

Thirty-nine pediatric intensive care units: 12 from northern Europe and 27 from southern Europe.

PATIENTS

All consecutive deaths were recorded over a 4-month period. Group 1 and group 2 included patients who died in northern and southern pediatric intensive care units, respectively.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Three hundred fifty children were enrolled, 68 in group 1 and 282 in group 2. The decision to forgo life-sustaining treatment was made in 116 children (group 1, n = 32; group 2, n = 84). In both groups, the decision was discussed by caregivers during a formal meeting. The decision to forgo life-sustaining treatment was more often made in northern countries than in southern ones (47% vs. 30%, p =.02). Parents were informed of this decision in 95% of cases in group 1 vs. 68% in group 2 (p =.01). In both groups, the final decision was made by the medical staff. Parents' contributions to the decision-making process did not differ between the two groups according to the practitioners' opinion. The decision was documented in the medical charts in 100% of the cases in group 1 and in 51% of the cases in group 2 (p =.0001).

CONCLUSIONS

The decision-making process appears to be similar between northern and southern European countries. The respective contributions of the parents and the medical staff in the final decision itself seem to be identical between northern and southern countries. However, in northern European countries, the level of parents' information about the decision-making process appears higher and the decision is more often documented in the medical chart.

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.

Ethical aspects in the management of the terminally ill patient in the pediatric intensive care unit

OBJECTIVE

To identify the prevalence of management plans and decision-making processes for terminal care patients in pediatric intensive care units.

METHODOLOGY

Evidence-based medicine was done by a systematic review using an electronic data base (LILACS, 1982 through 2000) and (MEDLINE, 1966 through 2000). The key words used are listed and age limits (0 to 18 years) were used.

RESULTS

One hundred and eighty two articles were found and after selection according to the exclusion/inclusion criteria and objectives 17 relevant papers were identified. The most common decisions found were do-not-resuscitation orders and withdrawal or withholding life support care. The justifications for these were "imminent death" and "unsatisfatory quality of life".

CONCLUSION

Care management was based on ethical principles aiming at improving benefits, avoiding harm, and when possible, respecting the autonomy of the terminally ill patient.

Decision making and satisfaction with care in the pediatric intensive care unit: findings from a controlled clinical trial

OBJECTIVE

To facilitate critical decision making and improve satisfaction with care among families of patients in a pediatric intensive care unit.

DESIGN

Prospective observational study followed by a nonrandomized controlled trial of a clinical intervention to identify conflicts and facilitate communication between families and the clinical team.

SETTING

The pediatric intensive care unit of a Boston teaching hospital.

PATIENTS

A total of 127 patients receiving care in the pediatric intensive care unit in 1998-1999 and their families.

INTERVENTIONS

Interviews were conducted with surrogates and decisionally capable older children concerning the adequacy of information provided, understanding, communication, and perceived decisional conflicts. Findings were relayed to the clinical team, who then developed tailored follow-up recommendations.

MEASUREMENTS AND MAIN RESULTS

A survey administered to surrogates at baseline and day 7 or intensive care unit discharge measured satisfaction with care. Information on patient acuity and hospital stay were extracted from medical records and hospital databases. Wilcoxon rank-sum tests and incidence rate comparisons were used to assess the impact of the intervention on satisfaction and sentinel decision making, respectively. Incidence rates of care plan decision making, including decisions to adopt a comfort-care-only plan and decisions to forego resuscitation, were lower among families who received the intervention. The intervention did not significantly affect satisfaction with care.

CONCLUSIONS

Prospectively screening for and intervening to mitigate potential conflict did not increase decision making or parental satisfaction with the care provided in this pediatric intensive care unit.

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.

Dying in the intensive care unit: collaborative multicenter study about forgoing life-sustaining treatment in Argentine pediatric intensive care units

OBJECTIVE

Describe modes of death and factors involved in decision-making together with life support limitation (LSL) procedures.

DESIGN

Prospective, descriptive, longitudinal, and noninterventional study.

SETTING

Sixteen pediatric intensive care units in Argentina.

PATIENTS

Every patient who died during a 1-yr period was included.

MEASUREMENTS AND MAIN RESULTS

Age, sex, length of stay (LOS), primary and admission diagnosis, underlying chronic disease (CD), postoperative condition (PO). Deaths were classified in four groups: a) failed cardiopulmonary resuscitation (CPR); b) do-not-resuscitate (DNR) status; c) withholding or withdrawing life-sustaining treatment (WH/WD); and d) brain death (BD). Justifications were classified as a) imminent death; b) poor long-term prognosis; c) poor quality of life; and d) family request. Data were collected from medical records and interviews with the attending physicians. Descriptive statistics were performed. Differences among groups were analyzed through contingency tables and analysis of variance when required. Relative risks and confidence intervals of variables potentially related to LSL were analyzed, and logistic regression was performed. There were 6358 admissions and 457 deaths. CPR was performed in 52%, DNR in 16%, WH/WD in 20%, and BD in 11% of dead patients. BD patients were older, LOS and CD prevalence were higher in the WH/WD group. Inotropic drugs were the most frequently limited treatment in 110 patients (55%), CPR in 72 (35.6%), and mechanical ventilation in 63 (31%). Imminent death was the most frequently reported justification for LSL. CD and more staff were associated with a higher probability of LSL.

CONCLUSIONS

Most of the patients in Argentina underwent CPR before their death. We have a high proportion of patients with CD (65%) and low BD diagnosis. PO condition decreased LSL probability in chronically ill patients. Do-not-resuscitate orders and withholding new treatments were the most common LSL. Active withdrawal was exceptional. The Ethics Committee was consulted in 5% of the LSL population.

Studying communication about end-of-life care during the ICU family conference: Development of a framework

PURPOSE

Family-clinician communication in the intensive care unit (ICU) about withholding and withdrawing life support occurs frequently, yet few data exist to guide clinicians in its conduct. The purpose of this study was to develop an understanding of the way this communication is currently conducted.

METHODS

We identified family conferences in the ICUs of 4 Seattle-area hospitals. Conferences were eligible if the physician leading the conference believed that discussion about withholding or withdrawing life support or the delivery of bad news was likely to occur and if all conference participants consented to participate. Fifty conferences were audiotaped, transcribed, and analyzed by using the principles of grounded theory.

RESULTS

We developed 2 frameworks for describing and understanding this communication. The first framework describes communication content, including introductions, information exchange, discussions of the future, and closings. The second framework describes communication styles and support provided to families and other clinicians and includes a variety of techniques such as active listening, acknowledging informational complexity and emotional difficulty of the situation, and supporting family decision making. These frameworks identify what physicians discuss, how they present and respond to issues, and how they support families during these conferences.

CONCLUSIONS

This article describes a qualitative methodology to understand clinician-family communication during the ICU family conference concerning end-of-life care and provides a frame of reference that may help guide clinicians who conduct these conferences. We also identify strategies clinicians use to improve communication and enhance the support provided. Further analyses and studies are needed to identify whether this framework or these strategies can improve family understanding or satisfaction or improve the quality care in the ICU.

Characteristics of deaths occurring in children's hospitals: implications for supportive care services

CONTEXT

End-of-life care is an important yet underdeveloped component of pediatric hospital services.

OBJECTIVES

We sought 1) to describe the demographics of children who die in children's hospitals, 2) to describe the prevalence of complex chronic conditions (CCCs) among these cases, and 3) to test the hypotheses that cases with a greater number of CCC diagnoses experience longer periods both of mechanical ventilation and of hospitalization before death. Design and Methods. We identified all deaths of patients 0 to 24 years old that occurred in the 60 hospitals contributing discharge data to the National Association of Children's Hospitals and Related Institutions data consortium for the years 1991, 1994, and 1997. We classified discharge diagnoses into 9 major categories of CCCs (cardiovascular, neuromuscular, malignancy, respiratory, renal, metabolic, gastrointestinal, hematologic/immunologic, and other congenital/genetic).

RESULTS

Of the 13 761 deaths identified, 42% had been admitted between 0 and 28 days of life, 18% between 1 and 12 months, 25% between 1 and 9 years, and 15% between 10 and 24 years. Fifty-three percent were white, 20% were black, and 9% were Hispanic. The principal payer was listed as a governmental source for 42% and a private insurance company for 35%. Based on all the discharge diagnoses recorded for each case, 40% had no CCC diagnosis, 44% had diagnoses representing 1 major CCC category, 13% had diagnoses representing 2 CCC categories, and 4% had diagnoses representing 3 or more CCC categories. Among cases that had no CCC diagnoses, the principal diagnoses were related to prematurity and newborn disorders for 32% of these cases, injuries and poisoning for 26%, and an assortment of acute and infectious processes for the remaining 42%. Mechanical ventilation was provided to 66% of neonates, 40% of infants, 36% of children, and 36% of adolescents. Cases with CCCs were more likely than non-CCC cases to have been mechanically ventilated (52% vs 46%), and to have been ventilated longer (mean: 11.7 days for CCC cases vs 4.8 days for non-CCC cases). The median duration of hospitalization was 4 days, while the mean was 16.4 days. After adjustment for age, sex, year, and principal payer, compared with patients with no CCC diagnoses, those with 1 major CCC category had a significantly lower hazard of dying soon after admission (hazard ratio [HR]: 0.60; 95% confidence interval [CI]: 0.57-0.62), those with 2 CCC categories even lower (HR: 0.53; 95% CI: 0.50-0.57), and those with 3 or more CCC categories the lowest hazard of rapid death (HR: 0.51; 95% CI: 0.46-0.57). This trend of diminishing hazard of rapid death was significant across the 3 groups of children with 1 or more CCCs.

CONCLUSIONS

Children's hospitals care for a substantial number of dying patients, who differ widely by age and medical conditions. Children who die in the hospital with CCCs are more likely to experience longer periods of mechanical ventilation and hospitalization before death.

The neonate with major malformations: experiences in a university children's hospital in the Netherlands

Advancements in medical technology over the last decades have greatly benefited perioperative care of newborns undergoing major surgical interventions. Yet, a proportion of these babies will not survive, and doctors are forced to face the difficult ethical question of whether, in cases of severe congenital malformations or acquired diseases, the expected quality of life justifies the decision to continue, withhold, or withdraw treatment. In a tripartite approach, the authors present their relevant experiences with these newborns in the pediatric surgical department of the Sophia Children's Hospital (SCH). First the authors evaluated the mortality pattern and causes of death in surgical neonates over 2 periods (1986 through 1990 and 1996 through 2000). The mortality rate was the same, 10%. Pattern of mortality was classified into 3 groups: nonpreventable, permissible, and preventable death. The most striking difference between both mortality groups existed between the percentage of preventable deaths, 14.5% in the earlier period, versus 5% in the most recent period. Half of the preventable deaths in the former period occurred in relation to postoperative, infectious treatment complications, such as inadequate sepsis management. These errors were not seen anymore in our recent evaluation. Second, the authors studied the physical and psychosocial adjustment of former patients, particularly those operated on for digestive tract anomalies. The follow-up period encompasses from 8 to 12 years showing that the physical functioning of these children was relatively good. With respect to their cognitive and psychosocial functioning it seems justified to conclude that they are at risk for lower cognitive functioning, learning problems, and possibly lower educational levels. Third, the authors decided that ethical questions related to surgical treatment of necrotizing enterocolitis (NEC) actually fits within the scope of this article. They hypothesized that a particular minimum birth weight could be a decisive factor for refraining from surgery on ethical grounds in the treatment of this particular disease. A total of 116 patients with NEC were identified over a 5-year study period. Seventy-five fell into the lowest birth weight group (<1,500 g). The operative mortality rate (21 patients) increased with decreasing birth weight: group A, 29% (A1, 31%; A2, 26%); group B, 23%; and group C, 0%. The authors were particularly interested in the long-term follow-up of the A1 group (BW < 1,000 g), and 18 of the 30 survivors of this group were available for follow-up. There were 2 survivors with short bowel syndrome. Early assessment and neurodevelopmental outcome, at least 2 years after surgery, showed that in 14 of these 18 (78%) there were no major handicaps. The other 4 patients had one or more major handicaps (cerebral palsy, mental and/or visual handicap, and hearing loss). NEC-related mortality after surgery is highest for patients with birth weight less than 1,000 g (31%). However, in view of the overall good 2-year follow-up results of the survivors, we feel unable to define a minimum birth weight that, as such, could serve as a cutoff point for deciding to forbear, on ethical grounds, surgical treatment for NEC. The picture represented by our tripartite investigation of life and death in and after the intensive care unit period serves as a mirror and truthfully reflects ethical questions of our medical practices.

Forgoing life-sustaining treatments: how the decision is made in French pediatric intensive care units

OBJECTIVES

The decision to forgo life support is frequently made in pediatric intensive care units (PICUs). A group of experts is currently preparing recommendations for guidelines concerning this decision-making process in France. We have performed a prospective study to help the experts. This study documents how children die in French PICUs and how the decision to limit life support is made.

DESIGN

A multicenter, prospective, cross-sectional study.

SETTING

Thirty-three multidisciplinary PICUs in university hospitals.

PATIENTS

All consecutive deaths were recorded over a 4-month period. Children who died after a medical decision to forgo life-sustaining treatment were included in group 1 and children who died from other causes were included in group 1.

MAIN RESULTS

A total of 264 consecutive children died, 40.1% from group 1 and 59.8% from group 2. Patients of both groups were primarily admitted for acute respiratory failure (group 1, 50.8%; group 2, 52.6%). Neurologic emergencies were more frequent in patients in group 1, whereas patients with cardiovascular failures were more frequent in group 2. When there was a question of whether to pursue life-sustaining treatment, the parents' opinions were recorded in 72.1% of cases. A specific meeting was called to make this decision in 80.1% of cases. This meeting involved the medical staff in all cases. Parents were aware of the meeting in 10.7% of cases. The conclusion of the meeting was reported to the parents in 18.7% of cases and documented in the patient's medical record in 16% of cases. Experts who were not members of the PICU staff were invited to give their opinion in 62.2% of cases.

CONCLUSIONS

The decision to forgo life-sustaining treatment is frequently made for children dying in French PICUs. Guidelines must be available to help the medical staff reach this decision. Knowledge of the decision-making process in French PICUs provides the experts with information needed to elaborate such recommendations.

End-of-life decision making by adolescents, parents, and healthcare providers in pediatric oncology: research to evidence-based practice guidelines

Participating in end-of-life decisions is life altering for adolescents with incurable cancer, their families, and their healthcare providers. However, no empirically developed and validated guidelines to assist patients, parents, and healthcare providers in making these decisions exist. The purpose of the work reported here was to use three sources (the findings of three studies on decision making in pediatric oncology, published literature, and recommendations from professional associations) to develop guidelines for end-of-life decision making in pediatric oncology. The study designs include a retrospective, descriptive design (Study 1); a prospective, descriptive design (Study 2); and a cross-sectional, descriptive design (Study 3). Settings for the pediatric oncology studies included a pediatric catastrophic illness research hospital located in the Midsouth (Studies 1 and 2); and that setting plus a children's hospital in Australia and one in Hong Kong (Study 3). Study samples included 39 guardians and 21 healthcare providers (Study 1); 52 parents, 10 adolescents, and 22 physicians (Study 2); and 43 parents (Study 3). All participants in the studies responded to six open-ended questions. A semantic content analysis technique was used to analyze all interview data. Four nurses independently coded each interview; interrater reliability per code ranged from 68% to 100% across studies. The most frequently reported influencing factors were "information on the health and disease status of the patient," "all curative options having been attempted," "trusting the healthcare team," and "feeling support from the healthcare provider." The agreement across studies regarding influencing factors provides the basis for the research-based guidelines for end-of-life decision making in pediatric oncology. The guidelines offer assistance with end-of-life decision making in a structured manner that can be formally evaluated and individualized to meet patient and family needs.

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.

The family conference as a focus to improve communication about end-of-life care in the intensive care unit: opportunities for improvement

The intensive care unit (ICU) represents a hospital setting in which death and discussion about end-of-life care are common, yet these conversations are often difficult. Such difficulties arise, in part, because a family may be facing an unexpected poor prognosis associated with an acute illness or exacerbation and, in part, because the ICU orientation is one of saving lives. Understanding and improving communication about end-of-life care between clinicians and families in the ICU is an important focus for improving the quality of care in the ICU. This communication often occurs in the "family conference" attended by several family members and members of the ICU team, including physicians, nurses, and social workers. In this article, we review the importance of communication about end-of-life care during the family conference and make specific recommendations for physicians and nurses interested in improving the quality of their communication about end-of-life care with family members. Because excellent end-of-life care is an important part of high-quality intensive care, ICU clinicians should approach the family conference with the same care and planning that they approach other ICU procedures. This article outlines specific steps that may facilitate good communication about end-of-life care in the ICU before, during, and after the conference. The article also provides direction for the future to improve physician-family and nurse-family communication about end-of-life care in the ICU and a research agenda to improve this communication. Research to examine and improve communication about end-of-life care in the ICU must proceed in conjunction with ongoing empiric efforts to improve the quality of care we provide to patients who die during or shortly after a stay in the ICU.

End-of-life decision-making and satisfaction with care: parental perspectives

OBJECTIVES

To evaluate parents' perceptions of the process by which decisions are made to limit or withdraw life support from critically ill children, and to evaluate parents' perceptions of their child's death in the pediatric intensive care unit (ICU) and their satisfaction with the care provided.

DESIGN

Survey.

SETTING

University teaching hospital.

PARTICIPANTS

Seventy-eight parents who experienced the death of a child in the ICU between January 1, 1995 and June 30, 1998.

INTERVENTIONS

Structured telephone interviews.

MEASUREMENTS AND MAIN RESULTS

Forty-one parents recalled discussing the limitation or withdrawal of life support from their child with a physician. Of these, 31 (76%) felt they had just the right amount of authority to make decisions for their child, 8 (20%) felt they had too little, and 1 (2%) felt they had too much. Those satisfied with their decision-making authority had more trust in their physician than those who were dissatisfied (5 vs. 1, p <.001 by Mann-Whitney U test, where 1 = no trust and 5 = complete trust). Factors identified by parents as being extremely important in the decision-making process included physician recommendations, diagnosis, expected neurologic recovery, and degree of pain and suffering. A total of 51 parents were with their child at the time of death. Although none regretted being present, 17 parents who were not present later wished they had been (p <.001, Fisher's exact test). The quality of care provided to parents by the ICU staff was graded (1 = poor; 5 = excellent). Eleven parents (14%) scored quality of care <or=2. These parents more often had a child die of an acute illness (6/11 vs. 8/67; p <.01), more often felt uninformed about their child's condition (9/11 vs. 19/67; p <.001), were less likely to understand the cause of death (4/11 vs. 51/67; p <.01) and less likely to have contact with hospital staff at home after the child's death (6/11 vs. 56/66; p <.05). These parents were also less likely to perceive staff as sympathetic (4/11 vs. 57/67; p <.001) or kind (5/11 vs. 65/67; p <.001).

CONCLUSIONS

Recommendations of physicians, nature of illness and expected neurologic recovery are important to parents making end-of-life decisions for their children. The establishment of trust is crucial in guiding parents through the decision-making process. Parental presence at the time of a child's death, the provision of adequate information, and a sympathetic environment may facilitate a healthy grief response.

[Mortality in a pediatric hospital. Six-year retrospective study]

AIMS

To define the characteristics of patients dying in a pediatric hospital, including causes and modes of death.

PATIENTS AND METHODS

This retrospective, descriptive, epidemiologic study was performed between 1 January 1990 and 31 December 1995. All patients who died in the hospital between these dates were included. Patients already dead on arrival (sudden infant death syndrome, children deceased during their transport), and those whose hospital records could not be found, were excluded.

RESULTS

A total of 375 children were studied, including 195 neonates. The sex ratio was 1.3. Ninety-one percent of deaths took place in three departments: intensive care, neurosurgery-neurology and oncology. Median duration of hospitalization was three days. The most common causes of deaths were accidents, neurologic diseases (particularly among neonates) and tumours. Analysis of modes of death revealed that 41.1% occurred following unsuccessful resuscitation, 38.8% were the result of withdrawal of life-support or a 'do not resuscitate' order and 21.6% resulted from brain death. Evolution of modes of death over the six years showed a reduction of cases with unsuccessful resuscitation, an increase in decisions of 'do not resuscitate' orders and withdrawal of life-support and no change in rates of brain death. Organs were made available for transplantation from 12 of the 81 children with brain death (14.8%).

CONCLUSION

Accidents were the most common cause of death. The distribution of deaths showed a clear increase in withdrawal or withholding of life-support care, relying on ethical decisions, which are more frequent than some years ago.

Can pediatricians define and apply the concept of brain death?

OBJECTIVE

We sought to determine pediatric residents' and attending physicians' ability to define brain death, their ability to apply this standard of death to a clinical scenario, and their knowledge regarding the legal necessity of confirmatory testing when determining death by brain criteria. We compared resident and attending self-confidence at discussing brain death with their ability to define brain death and apply this concept to a clinical scenario.

METHODOLOGY

A questionnaire was sent to 136 residents, postgraduate years 1 through 3, at four accredited pediatric training programs in the United States. Participation was tracked by return address. One follow-up request for participation was made. A similar procedure was followed for 140 faculty pediatricians at two of the institutions. Demographic information including level of training, subspecialty training, training program, and formal ethics training was collected. Respondents defined brain death, interpreted a clinical scenario, and stated whether confirmatory testing is legally required to determine death by brain criteria. Respondents rated their confidence at explaining brain death to a patient's family on a scale from 1 to 5.

RESULTS

Eighty-seven percent (118/136) of resident surveys were returned. Thirty-six percent (42/118) of the residents correctly defined brain death. Forty-three percent (51/118) of residents correctly interpreted the clinical scenario. Fifty-five percent (65/118) of the residents correctly recognized that brain death could be determined without a confirmatory test. Residents who correctly defined brain death were as confident as those who did not (2.8 +/- 1 vs 1.5 +/- 1). Residents who correctly interpreted the clinical scenario were as confident as those who did not (2.6 +/- 1 vs 1.9 +/- 0.9). Eighty percent (112/140) of attending physician surveys were returned. Thirty-nine percent (44/112) of attending physicians correctly defined brain death. Fifty-three percent (59/112) correctly interpreted the clinical scenario. Fifty-eight percent (65/112) recognized that brain death can be diagnosed without confirmatory testing. All pediatric intensivists (n = 12) correctly answered all three questions. Their performance was significantly better than other pediatricians. Attendings who correctly defined brain death were more confident than those who did not (4.2 +/- 1 vs 1.1 +/- 0. 9). Attendings who correctly interpreted the clinical scenario were more confident than those who did not (3.8 +/- 1.2 vs 2.2 +/- 1.2).

CONCLUSIONS

Pediatric residents and attendings have difficulty defining and applying the concept of brain death. This concept is difficult to grasp and internalize for many pediatricians. To ensure that critical decisions are made by knowledgeable physicians and well-informed families, more effective educational strategies need to be identified.

Withdrawal and limitation of life support in paediatric intensive care

OBJECTIVES

To compare the modes of death and factors leading to withdrawal or limitation of life support in a paediatric intensive care unit (PICU) in a developing country.

METHODS

Retrospective analysis of all children (< 12 years) dying in the PICU from January 1995 to December 1995 and January 1997 to June 1998 (n = 148).

RESULTS

The main mode of death was by limitation of treatment in 68 of 148 patients, failure of active treatment including cardiopulmonary resuscitation in 61, brain death in 12, and withdrawal of life support with removal of endotracheal tube in seven. There was no significant variation in the proportion of limitation of treatment, failure of active treatment, and brain death between the two periods; however, there was an increase in withdrawal of life support from 0% in 1995 to 8% in 1997-98. Justification for limitation was based predominantly on expectation of imminent death (71 of 75). Ethnic variability was noted among the 14 of 21 patients who refused withdrawal. Discussions for care restrictions were initiated almost exclusively by paediatricians (70 of 75). Diagnostic uncertainty (36% v 4.6%) and presentation as an acute illness were associated with the use of active treatment.

CONCLUSIONS

Limitation of treatment is the most common mode of death in a developing country's PICU and active withdrawal is still not widely practised. Paediatricians in developing countries are becoming more proactive in managing death and dying but have to consider sociocultural and religious factors when making such decisions.

Effects of prognosis, perceived benefit, and decision style on decision making and critical care on decision making in critical care

OBJECTIVE

To assess the effects of prognostic estimates, perceived benefit of treatment, and practice style on decision-making in critical care.

DESIGN

Randomized assignment of subjects to either of two versions of a questionnaire designed to elicit treatment decisions for six intensive care unit cases based on actual patients. One version offered optimistic survival forecasts; the other, pessimistic forecasts.

SUBJECTS

A random sample of 120 clinicians obtained from the Canadian Critical Care Society was contacted by mail. One version of the questionnaire was randomly assigned and mailed to each. Thirty-four replies, 17 for each version (response rate, 28%), were received and analyzed.

MEASUREMENTS AND MAIN RESULTS

A list of treatment/management options was developed for each case, in three categories: recommended, questionable, and unacceptable. Subjects were also able to list new options that they would order that were not on the list. The dependent variables were the number of actions ordered in each category and the total for each case. Perceived benefit was measured by comparing subjective estimates of the probability of survival with the optimistic/pessimistic forecast given in the case. Practice style was assessed by correlating the total number of actions ordered across all possible pairs of cases. There were no significant differences between the two questionnaires on actions ordered either by category or by amount per category. Perceived benefit did not appear to be an important factor in decision-making. However, statistically significant correlations provide evidence for practice style in intensive care unit decision-making on an interventionist/noninterventionist dimension.

CONCLUSIONS

There is no evidence that erroneous or biased prognostic estimates affect intensive care unit treatment choices. Neither the principle of maximizing expected utility nor the Rule of Rescue appear to affect these decisions systematically, but practice style does.

The potential benefits of the pediatric nonheartbeating organ donor

OBJECTIVE

To examine the population of the pediatric intensive care unit in a large children's hospital to determine the potential importance of pediatric nonheartbeating organ donors (NHBDs).

STUDY DESIGN

We analyzed retrospectively the 6307 admissions to the pediatric intensive care unit at the Children's Hospital of Philadelphia from January 1992 to July 1996 to identify all deaths. The hospital records of the children who had died were then reviewed to determine the mode of death, organ donation rate of heartbeating donors, and the number of potential NHBDs. Criteria for the NHBD included the decision to forgo life-sustaining therapy, death occurring within 2 hours of withdrawal of life support, and the absence of sepsis, HIV, hepatitis, or extracranial malignancy.

RESULTS

Of 319 deaths, 102 (32.0%) died with resuscitation, 84 (26.3%) were brain-dead, 111 (34.8%) had withdrawal of life support, and 22 (6.9%) were on do-not-resuscitate orders. Of the 84 brain-dead children, 74 (88.1%) were medically suitable heartbeating donors, and 43 (58.1%) donated organs. Of the 111 patients who had life support withdrawn, 31 (27.9%) qualified for NHBDs.

CONCLUSIONS

The routine use of the NHBD has the potential to increase organ donation at our institution by 42%. We discuss the ethical issues relating to NHBDs required to properly include these patients as potential organ donors.

Brain death in ICUs and associated nursing care challenges concerning patients and families

In order to document the incidence and causes of brain death (BD) and the frequency of organ donation (OD) in a Swedish University Hospital, a retrospective review of deaths in a neurosurgical department and in the general intensive care units (ICUs), was carried out for the period 1988-1994. BD diagnosis was established in 197 (10.6%) of all deaths (n = 1843). The hospital records of all BD patients were examined in detail following a specific study plan. The majority of the BD patients (89%) were acute admissions to hospital, and among them 81 were transferred between hospitals often over a long distance. Among the BD patients the total number of OD was 65 (33%). The most common diagnosis leading to BD was spontaneous intracerebral bleeding and traumatic head injury. The BD diagnosis was established by neurological examination (60%) and by cerebral angiography (40%). Of the BD patients, 50% died within 48 hours in the ICU and the majority of requests for OD (67%) were made to the relatives of these patients. The findings are discussed with focus on the workload and psychological stress of ICU nurses when caring for BD patients and their families; a task which includes taking part in processes concerning BD diagnosis information and OD requests.

Confidence in life-support decisions in the intensive care unit: a survey of healthcare workers. Canadian Critical Care Trials Group

OBJECTIVE

To examine the relationship between intensive care unit (ICU) healthcare workers' confidence and their decision to withdraw life support.

DESIGN

Cross-sectional survey of Canadian intensivists, ICU housestaff, and bedside nurses. Respondents chose the level of care (from comfort measures only to full aggressive care) for 12 patients described in clinical scenarios, and rated their confidence in their decisions.

SETTING

Thirty-seven Canadian university-affiliated hospitals.

PATIENTS

None.

INTERVENTIONS

We used discrete data analysis models to examine the association between the chosen level of care, confidence in the decisions, the clinical scenario, and healthcare worker group.

MEASUREMENTS AND MAIN RESULTS

The response rate was 1,361 (76%)/1,795; for this analysis, we used data from 1,306 respondents with completed questionnaires. Responses for each scenario varied widely among respondents. The level of care chosen was dependent on the scenario, the healthcare worker group, and the confidence with which the decisions were made (p < .001 for each). Intensivists were less aggressive than the ICU nurses, who were less aggressive than the housestaff, but the magnitude of effect was small. Overall, respondents were very confident about their decisions 34% of the time. After adjustment for clinical scenario and chosen level of care, intensivists were more confident than nurses, who were more confident than housestaff (40% of intensivists, 29% of nurses, and 23% of housestaff were very confident). In general, healthcare workers tended to be more confident when they chose extreme levels of care than when they chose intermediate levels of care. Considerable variability in responses to scenarios remained even when we considered only those responses made with the highest level of confidence.

CONCLUSIONS

While confidence in decisions about withdrawal of life support increases with seniority and authority, consistency of decisions may not. When given standard information, healthcare workers can make contradictory decisions yet still be very confident about the level of care they would administer.

Submersion injuries in children and adults

Drowning and near drowning remain a common cause of childhood death and disability. Toddlers aged one through four drown in private swimming pools. Submersions greater than 10 minutes and lack of CPR at the scene or the need for greater than 20 minutes of resuscitation portends a poor prognosis. Management of respiratory failure without neurologic impairment has the most successful outcome. Prevention of drowning morbidity is dependent on constant parental supervision, and immediate and expert CPR.

At the coalface--medical ethics in practice. Futility and death in paediatric medical intensive care

We have conducted a retrospective study of deaths on a paediatric medical intensive care unit over a two-year period and reviewed similar series from outside the UK. There were 89 deaths out of 651 admission (13.7% mortality). In almost two-thirds of the cases death occurred with a decision to limit medical treatment or withdraw mechanical ventilation, implying that additional or further therapy was considered futile. We highlight this as a crucially important issue in the practice of intensive care. More comprehensive studies are needed to help clinicians derive consensus on what constitutes a futile intervention, and therefore when such an intervention should be withheld. This will help families and society better understand the limitations of intensive care.

[Modality and causes of 259 deaths in a pediatric intensive care unit]

BACKGROUND

There are few data available from European pediatric intensive care units (PICU) regarding the modes of death and their causes.

POPULATION AND METHODS

Two hundred and fifty nine children, not including neonates, died in the PICU over a 7-year period (1987-1993). Data were obtained from a computerized data base and the retrospective review of medical records by two intensivists. Deaths were classified into three groups according to the terminal event: brain death (BD), unsuccessful resuscitation (UR), do-not-resuscitate order and limitation and/or withdrawal of therapy (LWT).

RESULTS

BD was the most common mode of death (38%); UR accounted for 34% and LWT for 28% of deaths. There was no significant annual variation in the proportion of BD, UR and LWT. Age and sex were similar in the three groups. The predominant organ system failure involved upon admission was the central nervous system (52%) in the LWT group, and the cardiovascular system (54%) in the UR group. Severe chronic disease (37%) and immunosuppression (19%) were more prevalent in the LWT group than in the BD group. Time from admission to death was longer in the LWT group (median = 119 hours) as compared to the UR group (10 hours) and the BD group (54 hours). Ten percent of the BD patients became organ transplant donors. Sixty-seven per cent of BD patients had medical contraindication for organ donation: parents did not accept organ donation in 61% of potential cases. Thirty deaths (12%) seemed to be avoidable; dehydration from acute infectious gastroenteritis (n = 7) was the most common cause of avoidable death.

CONCLUSIONS

The modes of death in our PICU were statistically not different from those seen in two of four North-American PICUs; LWT was less prevalent than in the two other PICUs, but the patient populations were very different (presence of neonates and many cardiovascular surgery patients). Assessment of the severity of illness at admission and of functional outcome in the survivors are mandatory in future studies.
