Variability in physician opinion on limiting pediatric life support

Physicians' attitudes and experiences about withholding/withdrawing life-sustaining treatments in pediatrics: a systematic review of quantitative evidence

BACKGROUND

One of the most important and ethically challenging decisions made for children with life-limiting conditions is withholding/withdrawing life-sustaining treatments (LST). As important (co-)decision-makers in this process, physicians are expected to have deeply and broadly developed views. However, their attitudes and experiences in this area remain difficult to understand because of the diversity of the studies. Hence, the aim of this paper is to describe physicians' attitudes and experiences about withholding/withdrawing LST in pediatrics and to identify the influencing factors.

METHODS

We systematically searched Pubmed, Cinahl®, Embase®, Scopus®, and Web of Science™ in early 2021 and updated the search results in late 2021. Eligible articles were published in English, reported on investigations of physicians' attitudes and experiences about withholding/withdrawing LST for children, and were quantitative.

RESULTS

In 23 included articles, overall, physicians stated that withholding/withdrawing LST can be ethically legitimate for children with life-limiting conditions. Physicians tended to follow parents' and parents-patient's wishes about withholding/withdrawing or continuing LST when they specified treatment preferences. Although most physicians agreed to share decision-making with parents and/or children, they nonetheless reported experiencing both negative and positive feelings during the decision-making process. Moderating factors were identified, including barriers to and facilitators of withholding/withdrawing LST. In general, there was only a limited number of quantitative studies to support the hypothesis that some factors can influence physicians' attitudes and experiences toward LST.

CONCLUSION

Overall, physicians agreed to withhold/withdraw LST in dying patients, followed parent-patients' wishes, and involved them in decision-making. Barriers and facilitators relevant to the decision-making regarding withholding/withdrawing LST were identified. Future studies should explore children's involvement in decision-making and consider barriers that hinder implementation of decisions about withholding/withdrawing LST.

Physician decision-making process about withholding/withdrawing life-sustaining treatments in paediatric patients: a systematic review of qualitative evidence

Background

With paediatric patients, deciding whether to withhold/withdraw life-sustaining treatments (LST) at the end of life is difficult and ethically sensitive. Little is understood about how and why physicians decide on withholding/withdrawing LST at the end of life in paediatric patients. In this study, we aimed to synthesise results from the literature on physicians’ perceptions about decision-making when dealing with withholding/withdrawing life-sustaining treatments in paediatric patients.

Methods

We conducted a systematic review of empirical qualitative studies. Five electronic databases (Pubmed, Cinahl®, Embase®, Scopus®, Web of Science™) were exhaustively searched in order to identify articles published in English from inception through March 17, 2021. Analysis and synthesis were guided by the Qualitative Analysis Guide of Leuven.

Results

Thirty publications met our criteria and were included for analysis. Overall, we found that physicians agreed to involve parents, and to a lesser extent, children in the decision-making process about withholding/withdrawing LST. Our analysis to identify conceptual schemes revealed that physicians divided their decision-making into three stages: (1) early preparation via advance care planning, (2) information giving and receiving, and (3) arriving at the final decision. Physicians considered advocating for the best interests of the child and of the parents as their major focus. We also identified moderating factors of decision-making, such as facilitators and barriers, specifically those related to physicians and parents that influenced physicians’ decision-making.

Conclusions

By focusing on stakeholders, structure of the decision-making process, ethical values, and influencing factors, our analysis showed that physicians generally agreed to share the decision-making with parents and the child, especially for adolescents. Further research is required to better understand how to minimise the negative impact of barriers on the decision-making process (e.g., difficult involvement of children, lack of paediatric palliative care expertise, conflict with parents).

A Single-Centered Randomized Controlled Trial of Primary Pediatric Intensivists and Nurses

Background: For long-stay patients (LSP) in pediatric intensive care units (PICU), frequently rotating providers can lead to ineffective information sharing and retention, varying goals and timelines, and delayed decisions, likely contributing to prolonged admissions. Primary intensivists (one physician serves as a consistent resource for the patient/family and PICU providers) and primary nurses (a small team of PICU nurses provide consistent bedside care) seek to augment usual transitory PICU care, by enhancing continuity and, potentially, decreasing length of stay (LOS). Methods: A single-centered, partially blinded randomized controlled trial of primary intensivists and nurses versus usual care. PICU patients admitted for or expected to be admitted for >10 days and who had ≥1 complex chronic condition were eligible. A block randomization with 1:1 allocation was used. The primary outcome was PICU LOS. Multiple secondary outcomes were explored. Results: Two hundred LSPs were randomized-half to receive primaries and half to usual care. The two groups were not significantly different in their baseline and admission characteristics. LSPs randomized to receive primaries had a shorter, but non-significant, mean LOS than those randomized to usual care (32.5 vs. 37.1 days, respectively, p = .19). Compared to LSPs in the usual care group, LSPs in the primary group had fewer unplanned intubations. Among LSPs that died, DNR orders were more prevalent in the primary group. Other secondary outcome and balance metrics were not significantly different between the two groups. Conclusion: Primary intensivists and nurses may be an effective strategy to counteract transitory PICU care and serve the distinctive needs of LSPs. However, additional studies are needed to determine the ways and to what extent they may accomplish this.

The impact of eligibility for primary attendings and nurses on PICU length of stay

PURPOSE

To examine whether primary attendings and/or nurses impact pediatric intensive care unit (PICU) length of stay (LOS) in long-stay patients (LSP).

MATERIALS AND METHODS

Retrospective observational cross-sectional study from 2012 to 2016 of 29,170 LSP (LOS ≥ 10 days) admitted to 64 PICUs that participated in the Virtual Pediatric Systems, LLC. Generalized linear mixed models were used to examine the association between being eligible for primary practices and LOS. Secondary outcomes of proportions of limitations and withdrawal of aggressive, life-sustaining interventions were also explored.

RESULTS

After controlling for several factors, being eligible for primary nurses and for primary attendings and nurses were associated with significantly lower mean LOS (8.9% and 9.7% lower, respectively), compared to not being eligible for any primary practice. Being eligible for primary attendings was associated with significantly higher mean LOS (9.6% higher). When the primary attendings were used for larger proportions of LSP, the practice was associated with significantly lower mean LOS. Limitations and withdrawal of aggressive interventions were more common in LSPs cared for in PICUs that utilized primary attendings.

CONCLUSIONS

The findings of lower LOS in LSP who were eligible for primary practices should induce more rigorous research on the impact of these primary practices.

Experience in Rehabilitation Medicine Affects Prognosis and End-of-Life Decision-Making of Neurologists: A Case-Based Survey

Background

Outcome predictions in patients with acute severe neurologic disorders are difficult and influenced by multiple factors. Since the decision for and the extent of life-sustaining therapies are based on the estimated prognosis, it is vital to understand which factors influence such estimates. This study examined whether previous professional experience with rehabilitation medicine influences physician decision-making.

Methods

A case vignette presenting a typical patient with an extensive brain stem infarction was developed and distributed online to clinical neurologists. Questions focused on prognosis, interpretation of an advanced directive, whether to withdraw life-sustaining treatments and information on prior rehabilitation experience from the survey respondent.

Results

Of the participating neurologists, 77% opted for the withdrawal of life-sustaining therapies (n = 70; response rate: 14.8%). This decision was not affected by age, gender, or length of clinical experience. Neurologists with experience in rehabilitation medicine tended to estimate a more positive prognosis than neurologists without, but this result was not significant (p = .13). There was an association between the intervention chosen and previous experience in rehabilitation; neurologists with experience in rehabilitation medicine opted significantly more often (31.8%) for continuing life-sustaining treatments than neurologists without such experience (8.7%, p = .04).

Conclusion

Our results indicate that there are subjective factors influencing decisions to limit life-sustaining treatments that are based on previous professional experience. This finding emphasizes the variability and cognitive bias of such decision processes and should be integrated into future guidelines for specialist training on end-of-life decision-making.

Decision Making and End-of-Life Care in Critically Ill Children

Objectives

1) To comment on the medical literature on decision making regarding end-of-life therapy, 2) to analyze the data on disagreement about such therapy, including palliative care, and withholding and withdrawal practices for critically ill children in the pediatric intensive care unit (PICU), and 3) to make some general recommendations.

Data Sources and Study Selection

All papers published in peer-reviewed journals, and all chapters on end-of-life therapy, or on conflict between parents and caregivers about end-of-life decisions in the PICU were retrieved.

Results

We found three case series, three systematic descriptive studies, two qualitative studies, four surveys, and many legal opinions, editorials, reviews, guidelines, and book chapters. The main determinants of end-of-life decisions are the child's age, premorbid cognitive condition and functional status, pain or discomfort, probability of survival, and quality of life. Risk factors in persistent conflict between parents and caregivers about end-of-life care include a grave underlying condition or an unexpected and severe event.

Conclusion

Making decisions about end-of-life care is a frequent event in the PICU. Children may need both intensive care and palliative care concurrently at different stages of their illness. Disagreements are more likely to be resolved if the root cause of the conflict is better understood.

Withholding and Withdrawal of Therapy in New Zealand Intensive Care Units (ICUs): A Survey of Clinical Directors

Withdrawing and withholding life-support therapy in patients who are unlikely to survive despite treatment are common practices in intensive care units (ICUs). The literature suggests there is a large variation in practice between different ICUs in different parts of the world. We conducted a postal survey among all public ICUs in New Zealand to investigate the pattern of practice in withholding and withdrawal of therapy. Nineteen ICUs responded to this survey and they represented 74% of all the public ICU beds and 83% of the annual ICU admissions. The percentage of ICU admissions with therapy withdrawn or withheld was less than 10% in most ICUs. Only a small percentage (21%) of ICUs had a formal policy in withholding and withdrawal of therapy. The timing of making the decision to withhold or withdraw therapy was very variable. The patient and/or the family, the primary medical team consultant, two or more ICU consultants, and ICU nurses were usually involved in the decision making process. ICU nurses were more commonly involved in the decision making process in smaller ICUs (5 beds vs 10 beds, P=0.03). The patient's pre-ICU quality of life, medical comorbidities, predicted mortality, predicted post-ICU quality of life, and the family's wishes were important factors in deciding whether ICU therapy would be withheld or withdrawn. Hospice ward or the patient's home was the preferred place for palliative care in 32% of the responses.

Physicians' attitudes when faced with life-threatening events in children with severe neurological disabilities

PURPOSE

Children with severe neurological disabilities are at an increased risk of acute, life-threatening events. We assessed physicians' attitudes when making decisions in these situations.

METHODS

We surveyed physicians in pediatric intensive care, neurology, and rehabilitation units in Swiss hospitals. The questionnaire explored participants' attitudes toward life-threatening situations in two scenarios: a child with profound intellectual and multiple disabilities (PIMD) and an infant with spinal muscular atrophy (SMA) type I.

RESULTS

The participation rate was 55% (52/95). There was a consensus favoring non-invasive ventilation and comfort care as well as avoiding tracheostomy and invasive ventilation. For the child with PIMD, 61% of participants opposed cardiopulmonary resuscitation (CPR), 51% for the child with SMA. Physicians with over 20 years of experience were significantly more opposed to providing CPR than less experienced colleagues.

CONCLUSIONS

Physicians held different views, influenced by personal factors. This highlights the importance of standardizing multidisciplinary processes toward approaching these complex situations.

Physician characteristics influence the trends in resuscitation decisions at different ages

AIM

We examined how physicians in different medical specialties would evaluate treatment decisions for vulnerable patients in need of resuscitation.

METHODS

A survey depicting six acutely ill patients from newborn infant to aged, all in need of resuscitation with similar prognoses, was distributed (in 2009) to a representative sample of 1650 members of the Norwegian Medical Association and 676 members of the Norwegian Pediatric Association.

RESULTS

There were 1335 respondents (57% participation rate). The majority of respondents across all specialties thought resuscitation was in the best interest of a 24 weeks' gestation preterm infant and would resuscitate the patient, but would also accept palliative care on the family's demand. Accepting a family's refusal of resuscitation was more common for the newborn infants. Specialists were overall similar in their answers, but specialty, age and gender were associated with different answers for the patients at both ends of the age spectrum.

CONCLUSION

Resuscitation decisions for the very young do not always seem to follow the best interest principle. Specialty and personal characteristics still have an impact on how we consider important ethical issues. We must be cognisant of our own valuations and how they may influence care.

Hospital Variation in Intensive Care Resource Utilization and Mortality in Newly Diagnosed Pediatric Leukemia

OBJECTIVES

To evaluate hospital-level variability in resource utilization and mortality in children with new leukemia who require ICU support, and identify factors associated with variation.

DESIGN

Retrospective cohort study.

SETTING

Children's hospitals contributing to the Pediatric Health Information Systems administrative database from 1999 to 2011.

PATIENTS

Inpatients less than 25 years old with newly diagnosed acute lymphocytic leukemia or acute myeloid leukemia requiring ICU support (n = 1,754).

INTERVENTIONS, MEASUREMENTS, AND MAIN RESULTS

Evaluated exposures included leukemia type, year of diagnosis, and hospital-wide proportion of patients with public insurance. The main outcome was hospital mortality. Wide variability existed in the ICU resources used across hospitals. Combined acute lymphocytic leukemia and acute myeloid leukemia mortality varied by hospital from 0% (95% CI, 0-14.8%) to 42.9% (95% CI, 17.7-71.1%). A mixed-effects model with a hospital-level random effect suggests significant variation across hospitals in mortality (p = 0.007). When including patient and hospital factors as fixed effects into the model, younger age, acute myeloid leukemia versus acute lymphocytic leukemia diagnosis, leukemia diagnosis prior to 2005, hospital-wide proportion of public insurance patients, and hospital-level proportion of leukemia patients receiving ICU care are significantly associated with mortality. The variation across hospitals remains significant with all patient factors included (p = 0.021) but is no longer significant after adjusting for the hospital-level factors proportion of public insurance and proportion receiving ICU care (p = 0.48).

CONCLUSIONS

Wide hospital-level variability in ICU resource utilization and mortality exists in the care of children with leukemia requiring ICU support. Hospital payer mix is associated with some mortality variability. Additional study into how ICU support could be standardized through clinical practice guidelines, impact of payer mix on hospital resources allocation to the ICU, and subsequent impact on patient outcomes is warranted.

Professional Responsibility, Consensus, and Conflict: A Survey of Physician Decisions for the Chronically Critically Ill in Neonatal and Pediatric Intensive Care Units

OBJECTIVE

To describe neonatologist and pediatric intensivist attitudes and practices relevant to high-stakes decisions for children with chronic critical illness, with particular attention to physician perception of professional duty to seek treatment team consensus and to disclose team conflict.

DESIGN

Self-administered online survey.

SETTING

U.S. neonatal ICUs and PICUs.

SUBJECTS

Neonatologists and pediatric intensivists.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We received 652 responses (333 neonatologists, denominator unknown; 319 of 1,290 pediatric intensivists). When asked about guiding a decision for tracheostomy in a chronically critically ill infant, only 41.7% of physicians indicated professional responsibility to seek a consensus decision, but 73.3% reported, in practice, that they would seek consensus and make a consensus-based recommendation; the second most common practice (15.5%) was to defer to families without making recommendations. When presented with conflict among the treatment team, 63% of physicians indicated a responsibility to be transparent about the decision-making process and reported matching practices. Neonatologists more frequently reported a responsibility to give decision making fully over to families; intensivists were more likely to seek out consensus among the treatment team.

CONCLUSIONS

ICU physicians do not agree about their responsibilities when approaching difficult decisions for chronically critically ill children. Although most physicians feel a professional responsibility to provide personal recommendations or defer to families, most physicians report offering consensus recommendations. Nearly all physicians embrace a sense of responsibility to disclose disagreement to families. More research is needed to understand physician responsibilities for making recommendations in the care of chronically critically ill children.

Attitudes of Slovene paediatricians to end-of-life care

AIMS

The aims of this study were to assess the attitudes of Slovene paediatricians to aspects of end-of-life (EOL) care and compare these attitudes between paediatric intensivists, paediatric specialists and paediatric residents.

METHODS

We performed a cross-sectional survey, using a specifically designed 43-item anonymous questionnaire.

RESULTS

We included 323 out of 586 Slovene paediatricians and residents, while 46.7% (151 of 323) of them responded to our questionnaire. More than half of intensivists (54.2%) had sought counsel from the Committee for Medical Ethics in the past as compared with 12.0% and 12.1% of specialists and residents, respectively (P < 0.001). The decision to limit life-sustaining treatment (LST) was found to be ethically acceptable in all groups of respondents. The highest level of agreement was found in residents (90.2%), followed by 83.3% among intensivists and 73.8% among specialists (P = not statistically significant (NS)). Disagreement with termination of hydration was highest among residents (85%) and intensivists (79.2%) while it was lower among specialists (66.7%) (P = NS). Patient's best interest, good clinical practice and patient's autonomous decision were graded as the top three aspects of the EOL care, while cost effectiveness and availability of patient's bed in intensive care were the least important.

CONCLUSIONS

The decision to limit LST measures was found to be ethically acceptable for Slovene paediatricians. No major differences were found among paediatric intensivists, specialist paediatricians and paediatric residents in the attitudes towards the EOL care.

End-of-life care in a regional level IV neonatal intensive care unit after implementation of a palliative care initiative

OBJECTIVE

We hypothesized that the implementation of a neonatal palliative care initiative will result in improved markers of end-of-life care.

STUDY DESIGN

A retrospective and prospective chart review of neonatal intensive care unit deaths was performed for 24 months before, 16 months during and 24 months after the implementation of palliative care provider education and practice guidelines (n=106). Ancillary care, redirection of care, palliative medication usage and outcome meetings in the last 48 h of life and basic demographic data were compared between epochs. Parametric and nonparametric analysis was performed.

RESULT

There was an increase in redirection of care and palliative medication usage and a decrease in variability of use of end-of-life interventions (P=0.012, 0.022 and <0.001).

CONCLUSION

The implementation of a neonatal palliative care initiative was associated with increases in palliative interventions for neonates in their final 48 h of life, suggesting that such an initiative may enhance end-of-life care.

Outcome of pediatric acute myeloid leukemia patients receiving intensive care in the United States

OBJECTIVE

Children with acute myeloid leukemia are at risk for sepsis and organ failure. Outcomes associated with intensive care support have not been studied in a large pediatric acute myeloid leukemia population. Our objective was to determine hospital mortality of pediatric acute myeloid leukemia patients requiring intensive care.

DESIGN

Retrospective cohort study of children hospitalized between 1999 and 2010. Use of intensive care was defined by utilization of specific procedures and resources. The primary endpoint was hospital mortality.

SETTING

Forty-three children's hospitals contributing data to the Pediatric Health Information System database.

PATIENTS

Patients who are newly diagnosed with acute myeloid leukemia and who are 28 days through 18 years old (n = 1,673) hospitalized any time from initial diagnosis through 9 months following diagnosis or until stem cell transplant. A reference cohort of all nononcology pediatric admissions using the same intensive care resources in the same time period (n = 242,192 admissions) was also studied.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

One-third of pediatric patients with acute myeloid leukemia (553 of 1,673) required intensive care during a hospitalization within 9 months of diagnosis. Among intensive care admissions, mortality was higher in the acute myeloid leukemia cohort compared with the nononcology cohort (18.6% vs 6.5%; odds ratio, 3.23; 95% CI, 2.64-3.94). However, when sepsis was present, mortality was not significantly different between cohorts (21.9% vs 19.5%; odds ratio, 1.17; 95% CI, 0.89-1.53). Mortality was consistently higher for each type of organ failure in the acute myeloid leukemia cohort versus the nononcology cohort; however, mortality did not exceed 40% unless there were four or more organ failures in the admission. Mortality for admissions requiring intensive care decreased over time for both cohorts (23.7% in 1999-2003 vs 16.4% in 2004-2010 in the acute myeloid leukemia cohort, p = 0.0367; and 7.5% in 1999-2003 vs 6.5% in 2004-2010 in the nononcology cohort, p < 0.0001).

CONCLUSIONS

Pediatric patients with acute myeloid leukemia frequently required intensive care resources, with mortality rates substantially lower than previously reported. Mortality also decreased over the time studied. Pediatric acute myeloid leukemia patients with sepsis who required intensive care had a mortality comparable to children without oncologic diagnoses; however, overall mortality and mortality for each category of organ failure studied was higher for the acute myeloid leukemia cohort compared with the nononcology cohort.

Determination of neurologic prognosis and clinical decision making in adult patients with severe traumatic brain injury: a survey of Canadian intensivists, neurosurgeons, and neurologists

OBJECTIVES

Accurate prognostic information in patients with severe traumatic brain injury remains limited, but mortality following the withdrawal of life-sustaining therapies is high and variable across centers. We designed a survey to understand attitudes of physicians caring for patients with severe traumatic brain injury toward the determination of prognosis and clinical decision making on the level of care.

DESIGN, SETTING, AND PARTICIPANTS

We conducted a cross-sectional study of intensivists, neurosurgeons, and neurologists that participate in the care of patients with severe traumatic brain injury at all Canadian level 1 and level 2 trauma centers.

INTERVENTION

None.

MEASUREMENTS

The main outcome measure was physicians' perceptions of prognosis and recommendations on the level of care.

MAIN RESULTS

Our response rate was 64% (455/712). Most respondents (65%) reported that an accurate prediction of prognosis would be most helpful during the first 7 days. Most respondents (>80%) identified bedside monitoring, clinical exam, and imaging to be useful for evaluating prognosis, whereas fewer considered electrophysiology tests (<60%) and biomarkers (<15%). In a case-based scenario, approximately one-third of respondents agreed, one-third were neutral, and one-third disagreed that the patient prognosis would be unfavorable at one year. About 10% were comfortable recommending withdrawal of life-sustaining therapies.

CONCLUSIONS

A significant variation in perceptions of neurologic prognosis and in clinical decision making on the level of care was found among Canadian intensivists, neurosurgeons, and neurologists. Improved understanding of the factors that can accurately predict prognosis for patients with traumatic brain injury is urgently needed.

Family factors affect clinician attitudes in pediatric end-of-life decision making: a randomized vignette study

CONTEXT

Conflicts between families and clinicians in pediatric end-of-life (EOL) care cause distress for providers, dissatisfaction for patients' families, and potential suffering for terminally ill children.

OBJECTIVES

We hypothesized that family factors might influence clinician decision making in these circumstances.

METHODS

We presented vignettes concerning difficult EOL decision making, randomized for religious objection to therapy withdrawal and perceived level of family involvement, to clinicians working in three Children's Hospital intensive care units. Additionally, attitudes about EOL care were assessed.

RESULTS

Three hundred sixty-four respondents completed the questionnaire, for an overall response rate of 54%. Respondents receiving the "involved family" vignette were more likely to agree to continue medical care indefinitely (P<0.0005). Respondents were marginally more likely to pursue a court-appointed guardian for those patients whose families had nonreligious objections to withdrawal (P=0.05). Respondents who thought that a fear of being sued affected decisions were less likely to pursue unilateral withdrawal (odds ratio 0.8, 95% CI=0.6-0.9). Those who felt personal distress as a result of difficult EOL decision making, thought they often provided "futile" care, or those who felt EOL care was effectively addressed at the institution were less likely to want to defer to the parents' wishes (range of odds ratios 0.7-1).

CONCLUSION

In this randomized vignette study, we have shown that family factors, particularly how involved a family seems to be in a child's life, affect what clinicians think is ethically appropriate in challenging EOL cases. Knowledge of how a family's degree of involvement may affect clinicians should be helpful to the clinical ethics consultants and offer some degree of insight to the clinicians themselves.

Struggling to do what is right for the child: pediatric life-support decisions among physicians and nurses in France and Quebec

This study examined (a) how physicians and nurses in France and Quebec make decisions about life-sustaining therapies (LSTs) for critically ill children and (b) corresponding ethical challenges. A focus groups design was used. A total of 21 physicians and 24 nurses participated (plus 9 physicians and 13 nurses from a prior secondary analysis). Principal differences related to roles: French participants regarded physicians as responsible for LST decisions, whereas Quebec participants recognized parents as formal decision-makers. Physicians stated they welcomed nurses' input but found they often did not participate, while nurses said they wanted to contribute but felt excluded. The LST limitations were based on conditions resulting in long-term consequences, irreversibility, continued deterioration, inability to engage in relationships and loss of autonomy. Ethical challenges related to: the fear of making errors in the face of uncertainty; struggling with patient/family consequences of one's actions; questioning the parental role and dealing with relational difficulties between physicians and nurses.

Barriers to conducting advance care discussions for children with life-threatening conditions

BACKGROUND AND OBJECTIVE

Advance care discussions (ACD) occur infrequently or are initiated late in the course of illness. Although data exist regarding barriers to ACD among the care of adult patients, few pediatric data exist. The goal of this study was to identify barriers to conducting ACD for children with life-threatening conditions.

METHODS

Physicians and nurses from practice settings where advance care planning typically takes place were surveyed to collect data regarding their attitudes and behaviors regarding ACD.

RESULTS

A total of 266 providers responded to the survey: 107 physicians and 159 nurses (54% response rate). The top 3 barriers were: unrealistic parent expectations, differences between clinician and patient/parent understanding of prognosis, and lack of parent readiness to have the discussion. Nurses identified lack of importance to clinicians (P = .006) and ethical considerations (P < .001) as impediments more often than physicians. Conversely, physicians believed that not knowing the right thing to say (P = .006) was more often a barrier. There are also perceived differences among specialties. Cardiac ICU providers were more likely to report unrealistic clinician expectations (P < .001) and differences between clinician and patient/parent understanding of prognosis (P = .014) as common barriers to conducting ACD. Finally, 71% of all clinicians believed that ACD happen too late in the patient's clinical course.

CONCLUSIONS

Clinicians perceive parent prognostic understanding and attitudes as the most common barriers to conducting ACD. Educational interventions aimed at improving clinician knowledge, attitudes, and skills in addressing these barriers may help health care providers overcome perceived barriers.

Donation after cardiocirculatory death: a call for a moratorium pending full public disclosure and fully informed consent

Many believe that the ethical problems of donation after cardiocirculatory death (DCD) have been "worked out" and that it is unclear why DCD should be resisted. In this paper we will argue that DCD donors may not yet be dead, and therefore that organ donation during DCD may violate the dead donor rule. We first present a description of the process of DCD and the standard ethical rationale for the practice. We then present our concerns with DCD, including the following: irreversibility of absent circulation has not occurred and the many attempts to claim it has have all failed; conflicts of interest at all steps in the DCD process, including the decision to withdraw life support before DCD, are simply unavoidable; potentially harmful premortem interventions to preserve organ utility are not justifiable, even with the help of the principle of double effect; claims that DCD conforms with the intent of the law and current accepted medical standards are misleading and inaccurate; and consensus statements by respected medical groups do not change these arguments due to their low quality including being plagued by conflict of interest. Moreover, some arguments in favor of DCD, while likely true, are "straw-man arguments," such as the great benefit of organ donation. The truth is that honesty and trustworthiness require that we face these problems instead of avoiding them. We believe that DCD is not ethically allowable because it abandons the dead donor rule, has unavoidable conflicts of interests, and implements premortem interventions which can hasten death. These important points have not been, but need to be fully disclosed to the public and incorporated into fully informed consent. These are tall orders, and require open public debate. Until this debate occurs, we call for a moratorium on the practice of DCD.

Ethical considerations in paediatric neurology: neuromuscular disease and epilepsy

The pace of developing technology with respect to many diagnostic tests, as well as available treatments including artificial ventilation, may have progressed at a faster rate than our ethical, humane ability to decide on the optimal choices for our patients. In fact, who should make these choices; physicians or patients and families? Certain ethical aspects of neuromuscular disorders and epilepsy are reviewed. For neuromuscular disease, the example of Duchenne muscular dystrophy (DMD) with regards to genetic testing, relatively early wheelchair placement and individualised invasive ventilation is discussed. In epilepsy, performing neurosurgery in severely impaired children is probably appropriate in some cases if desired by the family. Financial and human costs restrict therapies and testing for epilepsy as well as other neurological and medical diseases. Whether it is ethical to consider costs in medical treatment or not, it is certainly a reality.

Variability in the pediatric intensivists' threshold for withdrawal/limitation of life support as perceived by bedside nurses: a multicenter survey study

Background

We hypothesized that bedside nurses perceive significant variability in the pediatric intensivist thresholds for approaching a family about withdrawal/limitation of life-sustaining therapy.

Methods

All nurses working in four university-affiliated medical-surgical pediatric intensive care units staffed by 11, 7, 6, and 5 intensivists with 36, 18, 10, and 8 beds were sent three mailings of a survey asking questions about intensivist decisions for withdrawal/limitation of life-sustaining therapy. Responses were tabulated; chi-square compared results among centers; a p < 0.05 after Bonferroni correction was significant.

Results

The response rate was 205 of 415 (49%); 152 of 205 (74%) disagreed with the statement that each of the intensivists had the same threshold for approaching a family to suggest withdrawal/limitation of life-sustaining therapy, with no significant difference between centers. Also, 110 of 205 (54%) and 119 of 205 (58%) disagreed with the statement that each intensivist has the same threshold of the patient's chance for survival or projected quality of life when making a decision to withdraw/limit life-sustaining therapy with no significant difference between centers. The threshold to suggest withdraw/limit life-sustaining therapy based on chance of survival or projected quality of life differs between intensivists by at least 10% according to 113 of 184 (61%) and 121 of 184 (66%) nurses; the two larger centers had significantly higher difference among intensivists for projected quality of life. Fifty-five of 200 (27%) disagreed with the statement that they would have equal confidence in each intensivist accepting a recommendation for withdrawal/limitation of life-sustaining therapy for their own child, with no difference between centers.

Conclusions

Bedside pediatric intensive care unit nurses in this multicenter Canadian study perceive wide variability in intensivist thresholds for approaching a family to suggest withdrawal/limitation of life-sustaining therapy.

An investigation of dentists' and dental students' estimates of diagnostic probabilities

BACKGROUND

Research in medicine has shown that physicians have difficulty estimating the probability that a patient has a condition on the basis of available diagnostic evidence. They consistently undervalue baseline information about the patient relative to test information and are poor intuitive calculators of probability. The authors could not locate in the literature any studies of diagnostic probability estimates from baseline information and test data for dentists.

METHODS

Using two vignettes that contained different baseline information, dental students and clinical faculty members estimated the probability that the described hypothetical patient had the condition in question. Respondents also commented on the project.

CONCLUSIONS

Both groups of respondents overemphasized the importance of test evidence relative to baseline information, although experienced practitioners did so to a lesser extent than did students. Respondents, especially practitioners, expressed resistance to performing a diagnostic task that required precise estimates of probability.

CLINICAL IMPLICATIONS

Dentists appear to estimate diagnostic probabilities in an intuitive fashion, but they do so imprecisely. Clinical experience provides some protection against the bias of overestimating test evidence compared with baseline information. These findings raise questions about how practitioners use probability estimates and whether other models also may play a role. The incorporation of information from evidence-based dentistry into practice requires better understanding.

Morte digna da criança: análise de conceito

O estudo teve por objetivo descrever os antecedentes, atributos e conseqüências do conceito de morte digna da criança. Utilizou-se a estratégia de análise de conceito para avaliar os 40 artigos, tendo como foco publicações nas áreas médica e de enfermagem, que estudaram ou focalizaram a morte digna da criança. Os atributos do conceito de morte digna da criança incluem: qualidade de vida, cuidado centrado na criança e na família, conhecimento específico sobre cuidados paliativos, decisão compartilhada, alívio do sofrimento da criança, comunicação clara, relacionamento de ajuda e ambiente acolhedor. Poucos artigos trazem a definição de morte digna da criança e, quando isso ocorre, essa definição é vaga e, muitas vezes, ambígua entre os vários autores. Esse aspecto indica que o conceito ainda não é consistentemente definido, demandando estudos de sua manifestação na prática clínica, contribuindo com os cuidados no final da vida em pediatria.

What can we learn from the experiences of consultants around the time of a child's death?

AIMS

To describe how paediatric consultants report dealing with child and neonatal deaths as part of their daily work.

BACKGROUND

Paediatric consultants are involved with children and their families facing death through illness. This study focused on consultant's involvement around the time of death including: decision making and its associated difficulties, talking to parents and the use of coping strategies. Consultants with more than 5 years experience were asked what experience has taught them and consultants with less that 5 years experience were asked what they felt was the biggest change from being a registrar.

METHODS

Following Multicentre Research Ethics Committee (MREC) approval a pre-piloted self-administered questionnaire (with one reminder) was sent to 100 of the paediatric consultants within the South West Region.

RESULTS

There was a 61% response rate. Most consultants had experienced a variety of opinions when talking to parents about when to withdraw or withhold life sustaining treatment. Uncertainty (39%) and disagreement (44%) made decision making difficult. Discussion with colleagues (41%), 'honesty and time with parents' (28%) and planning or 'stage managing' talking with parents (38%) were well used strategies to deal with this. New consultants find responsibility and decision making the biggest change from being a registrar.

CONCLUSIONS

We can learn much from the experiences of consultants around the time of a child's death. Their approach during resuscitation and withdrawal or withholding life sustaining treatment describes many strategies that have been developed to ease the often complex decision-making process. Although consultants have built up personal support networks and individual coping strategies many recognize that these are not all encompassing and some harbour unresolved feelings of grief. Enabling health professionals to genuinely care, 'giving oneself totally yet preserving oneself totally' remains a challenge.

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.

Patient preferences between surgical and medical treatment in Crohn's disease

PURPOSE

Crohn's disease poses difficult choices in which the most appropriate treatment option is not always obvious. When this state of uncertainty exists, patients' preferences should have an increasingly important part of clinical decision making. The purpose of this study was to compare patients' preferences for surgical intervention in Crohn's disease with the preferences of surgeons and gastroenterologists.

METHODS

Outpatients with Crohn's disease were interviewed to quantify their preferences for six scenarios by using the prospective preference measure. An identical questionnaire was mailed to all Australian and New Zealand colorectal surgeons and a random sample of 300 Australian gastroenterologists.

RESULTS

Forty-one of 123 patients with Crohn's disease (33 percent), 92 of 127 colorectal surgeons (72 percent), and 74 of 272 gastroenterologists (27 percent) participated. There were significant differences between patients and gastroenterologists for three of six scenarios and between surgeons and gastroenterologists in four of six scenarios. Seventy-six percent of gastroenterologists were willing to gamble to avoid an ileocolic resection compared with 37 percent of surgeons (chi-squared = 25.44; P < 0.0001) and 39 percent of patients (chi-squared = 15.44; P < 0.001).

CONCLUSIONS

Patients and clinicians were able to trade and gamble life expectancy as a measure of preference for varying hypothetical surgical treatments, even though these treatment options impacted on quality of life rather than survival. Patients' preferences did not align with clinicians. For most scenarios, colorectal surgeons' preferences were significantly different to those of gastroenterologists.

Toward interventions to improve end-of-life care in the pediatric intensive care unit

Although children account for only about 3% of all deaths that occur in the United States each year, these patients and their families have needs that are uniquely different from those of adult patients. To date, however, no research on interventions to improve end-of-life care in the pediatric intensive care unit (PICU) has been performed. This review seeks to facilitate and inform future interventional studies by summarizing existing descriptive data about end-of-life care in this setting. These data are organized around six domains that have been identified as critical to high-quality, family-centered care: 1) support of the family unit; 2) communication with the child and family about treatment goals and plans; 3) ethics and shared decision making; 4) relief of pain and other symptoms; 5) continuity of care; and 6) grief and bereavement support. These data are integrated and used to develop evidence-based suggestions for a variety of interventions that could be implemented and then evaluated for their potential contribution to improving the care of children dying in the PICU.

End of Life in the Pediatric Burn Patient

Up to 60% of deaths in pediatric intensive care units occur after placing limits upon life-sustaining treatment. Two-thirds of limitations are made on the last day of life. Our aim was to characterize the timing, indications, and implementation of "do not resuscitate" (DNR) orders and the withdrawal of support from children with severe burns. A retrospective evaluation was conducted of all deaths in a pediatric burn unit over a 7-year period. Values are presented as mean +/- SD; two-tailed t-tests and Fisher's exact tests were used for analysis. Of the 29 deaths (total admissions = 1261; 2.3% death rate), 12 were of patients with DNR status. Active withdrawal of support occurred for 15 patients: 10 with DNR orders, 5 without. There was no difference in age, burn size, inhalation injury, etiology of injury, cause of death, intensive care unit days, or ventilator days between DNR patients and non-DNR patients. Of the 12 patients with DNR status, only five had orders indicating no cardiopulmonary resuscitation (CPR), no vasopressors, and no cardioversion. The mean time from DNR to death was 22.9 +/- 49.6 hours (median, 2.75 hours). Patients without DNR orders before death had more CPR attempts (0.8 +/- 0.6 vs. 0.3 +/- 0.6; P < .05). At the time of death, few patients with DNR orders were receiving vasopressors (two patients) or underwent CPR (1 patient). Of the 17 patients without DNR orders, 12 underwent resuscitative efforts: CPR (11), vasopressors (12), or cardioversion (9). No resuscitative efforts were undertaken for four children, two with DNR orders. For the acutely injured child there is a strong tendency to wait until the last possible hours of life to address limitation of life-sustaining measures. Documentation of limitation of care was not previously addressed in nearly a third of cases in which support was actively withdrawn. Once a decision to limit support was made, the majority of children proceeded rapidly to death. Further evaluation of the indications, timing, and implementation of DNR orders for children with severe burns is warranted.

Defining the clinical improvement in cancer drug therapy: implications for priority setting in healthcare

An explicit approach to funding decisions has become increasingly important to ensure fairness and consistency in resource allocation in cancer therapy. Funding decisions are often based on whether a treatment is 'medically necessary' and the level of clinical improvement. Currently, there is a lack of consensus on defining different levels of clinical improvement, leading to controversies on the values placed on different outcomes and degrees of clinical improvements during funding evaluation. More information on how clinicians and patients define the levels of clinical improvement can help ensure the evaluation and decision-making processes of funding to become more predictable, consistent, understandable and therefore accountable to providers and consumers of healthcare.

What influences parents' decisions to limit or withdraw life support?

OBJECTIVE

Decisions to forgo life support from critically ill children are commonly faced by parents and physicians. Previous research regarding parents' perspectives on the decision-making process has been limited by retrospective methods and the use of closed-ended questionnaires. We prospectively identified and described parents' self-reported influences on decisions to forgo life support from their children. Deeper understanding of parents' views will allow physicians to focus end-of-life discussions on factors important to parents and help resolve conflicts.

DESIGN

Prospective, qualitative pilot study.

SETTING

Pediatric intensive care unit of a university-affiliated children's hospital.

PARTICIPANTS

A total of 14 parents of ten children whose pediatric intensive care unit physician had made a recommendation to limit or withdraw life support.

INTERVENTIONS

: In-depth, semistructured interviews were conducted with parents during their decision-making process.

MEASUREMENTS AND MAIN RESULTS

Factors influencing the parents in this study in their decision to forgo life support included their previous experience with death and end-of-life decision making for others, their personal observations of their child's suffering, their perceptions of their child's will to survive, their need to protect and advocate for their child, and the family's financial resources and concerns regarding life-long care. Parents in this study expressed the desire to do what is best for their child but struggled with feelings of selfishness, guilt, and the need to avoid agony and sorrow. Physician recommendations, review of options, and joint formulation of a plan helped parents gain a sense of control over their situation. Parents of eight children agreed to forgo life support and parents of two did not.

CONCLUSIONS

Prospective interviews with open-ended questions identified factors influencing parents' decision making not previously described in the critical care literature such as parents' past experiences with end-of-life decisions and their anticipated emotional adjustments and future resources. Inclusion of these factors into discussions is important to parents and may facilitate decisions regarding the limitation or withdrawal of life support.

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.
