Predictors of withdrawal of life support after burn injury

Palliative Care Utilization in Burn Patients

Background: Burn injuries are a common cause for hospitalization, and severe burns have an increased risk of death in patients with advanced age, inhalational injury, comorbid conditions. Very little is known about the utilization of palliative care consultation in burn patients. Objective: The aim of this study was to evaluate the factors influencing the utilization of inpatient palliative care consultation for patients with severe burn injuries. Methods: This was a retrospective chart review study at a single burn center. Results: Seventeen out of 191 patients (8.9%) received a palliative care consultation with the average time for consultation of 10.3 days. Factors that appear to impact consultation were age, presence of inhalational injury, and multiple comorbid conditions. Conclusion: Inpatient palliative care consultation was underutilized in patients with severe burn injurie. Further research into the outcomes of palliative care consultation could help further support the utility of early involvement in burn patients.

Exploring clinicians' decision-making processes about end-of-life care after burns: A qualitative interview study

INTRODUCTION

Little is known about treatment decision-making experiences and how/why particular attitudes exist amongst specialist burn clinicians when faced with patients with potentially non-survivable burn injuries. This exploratory qualitative study aimed to understand clinicians' decision-making processes regarding end-of-life (EoL) care after a severe and potentially non-survivable burn injury.

METHODS

Eleven clinicians experienced in EoL decision-making were interviewed via telephone or video conferencing in June-August 2021. A thematic analysis was undertaken using a framework approach.

RESULTS

Decision-making about initiating EoL care was described as complex and multifactorial. On occasions when people presented with 'unsurvivable' injuries, decision-making was clear. Most clinicians used a multidisciplinary team approach to initiate EoL; variations existed on which professions were included in the decision-making process. Many clinicians reported using protocols or guidelines that could be personalised to each patient. The use of pathways/protocols might explain why clinicians did not report routine involvement of palliative care clinicians in EoL discussions.

CONCLUSION

The process of EoL decision-making for a patient with a potentially non-survivable burn injury was layered, complex, and tailored. Processes and approaches varied, although most used protocols to guide EoL decisions. Despite the reported complexity of EoL decision-making, palliative care teams were rarely involved or consulted.

The Impact of Burn Size on Community Participation: A Life Impact Burn Recovery Evaluation (LIBRE) Study

OBJECTIVE

To assess the association of burn size and community participation as measured by the LIBRE Profile.

SUMMARY OF BACKGROUND DATA

Burn size is an established clinical predictor of survival after burn injury. It is often a factor in guiding decisions surrounding early medical interventions; however, literature is inconclusive on its relationship to quality of life outcomes.

METHODS

This is a secondary data analysis of a cross-sectional survey of adult burn survivors. Self-reported data were collected between October 2014 and December 2015 from 601 burn survivors aged ≥18 years with ≥5% total body surface area (TBSA) or burns to critical areas. Sociodemographic characteristics were compared between participants with small burns (≤40% TBSA burned) and large burns (>40% TBSA burned). Ordinary least squares regression models examined associations between burn size and LIBRE Profile scale scores with adjustments for sex, current work status, burns to critical areas, and time since burn injury.

RESULTS

The analytic sample comprised 562 participants with data available for burn size. 42% of respondents had large burns (>40% TBSA burned) and 58% reported smaller burns (TBSA ≤40%). In adjusted regression models, patients with large burns tended to score lower on the Social Activities and Work & Employment scales ( P < 0.05) and higher on the Family & Friends scale ( P < 0.05). Participants with burns >40% TBSA scored lower for several individual items in the Social Activities scale and one item in the Work & Employment scale ( P < 0.05).

CONCLUSIONS

Increasing burn size was found to be negatively associated with selected items of Work & Employment and Social Activities, but positively associated with aspects of Family & Friend Relationships. Future longitudinal studies are necessary to assess and understand the long-term social impact of burn injuries on adult populations.

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

OBJECTIVES

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

METHODS

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

RESULTS

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

SIGNIFICANCE OF RESULTS

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

Choosing wisely in burn care

BACKGROUND

The Choosing Wisely Campaign was launched in 2012 and has been applied to a broad spectrum of disciplines in almost thirty countries, with the objective of reducing unnecessary or potentially harmful investigations and procedures, thus limiting costs and improving outcomes. In Canada, patients with burn injuries are usually initially assessed by primary care and emergency providers, while plastic or general surgeons provide ongoing management. We sought to develop a series of Choosing Wisely statements for burn care to guide these practitioners and inform suitable, cost-effective investigations and treatment choices.

METHODS

The Choosing Wisely Canada list for Burns was developed by members of the Canadian Special Interest Group of the American Burn Association. Eleven recommendations were generated from an initial list of 29 statements using a modified Delphi process and SurveyMonkey™.

RESULTS

Recommendations included statements on avoidance of prophylactic antibiotics, restriction of blood products, use of adjunctive analgesic medications, monitoring and titration of opioid analgesics, and minimizing 'routine' bloodwork, microbiology or radiological investigations.

CONCLUSIONS

The Choosing Wisely recommendations aim to encourage greater discussion between those involved in burn care, other health care professionals, and their patients, with a view to reduce the cost and adverse effects associated with unnecessary therapeutic and diagnostic procedures, while still maintaining high standards of evidence-based burn care.

Burn Care Specialists' Views Towards End of Life Decision-Making in Patients with Severe Burn Injury: Findings from an Online Survey in Australia and New Zealand

Burn care clinicians are required to make critical decisions regarding the withholding and withdrawal of treatment in patients with severe and potentially non-survivable burn injuries. Little is known about how Australian and New Zealand burn care specialists approach decision-making for these patients. This study aimed to understand clinician beliefs, values, considerations, and difficulties regarding palliative and end of life care (EoL) discussions and decision-making following severe burn injury in Australian and New Zealand burn services. An online collected respondent and institutional demographic data, as well as information about training and involvement in palliative care/EoL decision-making discussions from nurses, surgeons, and intensivists in Australian and New Zealand hospitals with specialist burn services. Twenty-nine burns nurses, 26 burns surgeons, and 15 intensivists completed the survey. Respondents were predominantly female (64%) and had a median 15 years of experience in treating burn patients. All respondents received little training in EoL decision-making during their undergraduate education; intensivists reported receiving more on-the-job training. Specialist clinicians differed on who they felt should contribute to EoL discussions. Ninety percent of respondents reported injury severity as a key factor in their decision-making to withhold or withdraw treatment, but less than half reported considering age in their decision-making. Approximately two-thirds indicated a high probability of death or a poor predicted quality of life influenced their decision-making. The three cohorts of clinicians had similar views towards certain aspects of EoL decision-making. Qualitative research could provide detailed insights into the varying perspectives held by clinicians.

Treatment Decisions in Patients with Potentially Non-Survivable Burn Injury in Australia and New Zealand: A Registry-based Study

Whilst burn-related mortality is rare in high-income countries, there are unique features related to prognostication that make examination of decision-making practices important to explore. Compared to other kinds of trauma, burn patients (even those with non-survivable injuries) may be relatively stable after injury initially. Complications or patient comorbidity may make it clear later in the clinical trajectory that ongoing treatment is futile. Burn care clinicians are therefore required to make decisions regarding the withholding or withdrawal of treatment in patients with potentially non-survivable burn injury. There is yet to be a comprehensive investigation of treatment decision practices following burn injury in Australia and New Zealand. Data for patients admitted to specialist burn services between July 2009 and June 2020 were obtained from the Burns Registry of Australia and New Zealand. Patients were grouped according to treatment decision: palliative management, active treatment withdrawn, and active treatment until death. Predictors of treatment initiation and withholding or withdrawing treatment within 24 hours were assessed using multilevel mixed-effects logistic regression. Descriptive comparisons between treatment groups were made. Of the 32,186 patients meeting study inclusion criteria, 327 (1.0%) died prior to discharge. Fifty-six patients were treated initially with palliative intent and 227 patients had active treatment initiated and later withdrawn. Increasing age and burn size reduced the odds of having active treatment initiated. We demonstrate differences in demographic and injury severity characteristics as well as end of life decision-making timing between different treatment pathways pursued for patients who die in-hospital. Our next step into the decision-making process is to gain a greater understanding of the clinician's perspective (e.g., through surveys and/or interviews).

Epidemiology of Burn-Related Morbidity and Mortality in Patients Over Eighty Years of Age

Burns cause greater morbidity and mortality in older patients owing to the physiological changes and functional status declines with age. We sought to characterize the epidemiology of burn injuries in the patient population aged over eighty years. A retrospective analysis of all patients aged >80 years admitted to a tertiary burn center in Brazil over a 10-year period was conducted. Multiple parameters including comorbidities, body surface area(BSA) burned, intensive care unit(ICU) admissions, inhalation injury and revised Baux score were analyzed to assess association with mortality. 26 patients were identified. The overall mortality rate was 42.3%. The mortality rate increased with the TBSA, with 100% mortality at >20% total BSA involvement(p<0.001). Inhalation injury occurred in 3(11.5%) patients, all of whom suffered mortality(p<0.001). ICU admission was necessary for 14(53.8%) patients, out of which 11(78.6%) did not survive(p<0.001). The revised Baux score had a significant impact on the mortality, with higher values among patients who did not survive(89.2 ± 6.2 versus 110.7 ± 17.9,p < 0.001). Burns cause high mortality in the octogenarian and nonagenarian populations. It is important to stratify patients at high risk, institute prompt treatment and discuss goals of care early on for optimal patient outcomes.

Racial and ethnic disparities in withdrawal of life-sustaining treatment after non-head injury trauma

BACKGROUND

Little is known about potential disparities in end-of-life care in trauma. We examined racial/ethnic differences in withdrawal of life-sustaining treatment (WLST) in non-head injury trauma.

METHODS

We retrospectively analyzed the National Trauma Databank (2017-2018), including patients ≥ 18 years without head injury. We performed a bivariate analysis by WLST status and used logistic regression to estimate adjusted odds of WLST by racial/ethnic group.

RESULTS

Of 942,914 identified, 20,052 (2.1%) died. Of those who died, WLST occurred in 29.9%. The adjusted odds of WLST were lower in Blacks (OR 0.48, 95% CI 0.41-0.57) and Hispanics (OR 0.71, 95% CI 0.57-0.89) than Whites. The predicted probability of WLST in Black patients remained lower than Whites at 30 days.

CONCLUSIONS

Among non-head injured dying patients, Blacks and Hispanics are less likely to utilize WLST than Whites. Further investigation into the socio-cultural norms and institutional distrust influencing these differences is imperative.

Early Palliative Care Consultation in the Burn Unit: A Quality Improvement Initiative to Increase Utilization

Despite significant morbidity and mortality for major burns, palliative care consultation (PCC) is underutilized in this population. The purpose of this study is to examine the impact of a protocol using recommended "triggers" for PCC at a single academic burn center. This is a retrospective review of patient deaths over a four-year period. Use of life-sustaining treatments, comfort care (de-escalation of one or more life-sustaining treatments) and do not attempt resuscitation (DNAR) orders were determined. Use of PCC was compared during periods before and after a protocol establishing recommended triggers for early (<72 hrs of admission) PCC was instituted in 2019. A total of 33 patient deaths were reviewed. Most patients were male (n=28, 85%) and median age was 62 years [IQR 42-72]. Median revised Baux score was 112 [IQR 81-133]. Many patients had life-sustaining interventions such as intubation, dialysis, or cardiopulmonary resuscitation, often prior to admission. Amongst patients who survived >24 hrs, 67% (n=14/21) had PCC. Frequency of PCC increased after protocol development, with 100% vs. 36% of these patients having PCC before death (p=0.004). However, even during the later period, less than half of patients had early PCC despite meeting criteria at admission. In conclusion, initiation of life-sustaining measures in severely injured burn patients occurs prior to or early during hospitalization. Thus, value-based early goals of care discussions are valuable to prevent interventions that do not align with patient values and assist with de-escalation of life-sustaining treatment. In this small sample, we found that while there was increasing use of PCC overall after developing a protocol of recommended triggers for consultation, many patients who met criteria at admission did not receive early PCC. Further research is needed to elucidate reasons why providers may be resistant to PCC.

Nonmedical Factors Influencing Early Deaths in Burns: A Study of the National Burn Repository

It is well-established that survival in burn injury is primarily dependent on three factors: age, percent total-body surface area burned (%TBSA), and inhalation injury. However, it is clear that in other (nonburn) conditions, nonmedical factors may influence mortality. Even in severe burns, patients undergoing resuscitation may survive for a period of time before succumbing to infection or other complications. In some cases, though, families in conjunction with caregivers may choose to withdraw care and not resuscitate patients with large burns. We wanted to investigate whether any nonmedical socioeconomic factors influenced the rate of early deaths in burn patients. The National Burn Repository (NBR) was used to identify patients that died in the first 72 hours after injury and those that survived more than 72 hours. Both univariate and multivariate regression analyses were used to examine factors including age, gender, race, comorbidities, burn size, inhalation injury, and insurance type, and determine their influence on deaths within 72 hours. A total of 133,889 burn patients were identified, 1362 of which died in the first 72 hours. As expected, the Baux score (age plus burn size), and inhalation injury predicted early deaths. Interestingly, on multivariate analysis, patients with Medicare (p = .002), self-pay patients (p < .001), and those covered by automobile policies (p = .045) were significantly more likely to die early than those with commercial insurance. Medicaid patients were more likely to die early, but not significantly (p = .188). Worker's compensation patients were more likely to survive the first 72 hours compared with patients with commercial insurance (p < .001). Men were more likely to survive the early period than women (p = .043). On analysis by race, only Hispanic patients significantly differed from white patients, and Hispanics were more likely to survive the first 72 hours (p = .028). Traditional medical factors are major factors in early burn deaths. However, these results show that nonmedical socioeconomic factors including race, gender, and especially insurance status influence early burn deaths as well.

End-Of-Life (EOL) Comfort Care And Withdrawal Of Life Support (WLS) Of Severely Burned Patients: A Review Of The Literature

Ensuring burn patients get appropriate care without pursuing futile treatment has always constituted a challenging balance for burn surgeons. Patients with no prospect of cure who eventually die should potentially experience more comfortable and peaceful end-of-life (EoL) care. Recognizing that death for some patients is inevitable and can only be postponed but not avoided would open the way to a more humane comfort care for such patients. Though comfort EoL services are still not universal in burns intensive care units (ICU) and disparities still exist in access, and use of palliative care appears underutilized, its integration in the burns ICU has increased over the past decade with undeniable benefits. Palliative care consultations should be considered in select burn patients for whom survival is highly unlikely.

The Role of Palliative Care in Burns: A Scoping Review

CONTEXT

Patients with severe burns may face distressing symptoms with a high risk of mortality as a result of their injury. The role of palliative care in burns management remains unclear.

OBJECTIVE

To appraise the literature on the role of palliative care in burns management.

METHODS

We used scoping review with searches in 12 databases from their inception to August 2019. The citation retrieval and retention are reported in a PRISMA statement.

FINDINGS

39 papers comprising of 30 primary studies (26 from high-income and four from middle-income countries), four reviews, two editorials, two guidelines, and one expert board review document were retained in the review. Palliative care is used synonymously with comfort and end-of-life care in burns literature. Comfort care is mostly initiated when active treatment is withheld (early deaths) or withdrawn (late deaths), limiting its overall benefits to burn patients, their families, and health care professionals. Futility decisions are usually complex and challenging, particularly for patients in the late death category, and it is unclear if these decisions result in timely commencement of comfort care measures. Three comfort care pathways were identified, but it remained unclear how these pathways evaluated "good death" or supported the family which creates the need for the development of other evidence-based guidelines.

CONCLUSION

Palliative care is applicable in burns management, but its current role is mostly confined to the end-of-life period, suggesting that it is not been fully integrated in the management process. Evidence-based guidelines are needed to support the integration and delivery of palliative care in the burn patient population.

Do patients, families, and healthcare teams benefit from the integration of palliative care in burn intensive care units? Results from a systematic review with narrative synthesis

BACKGROUND

Burn units are intensive care facilities specialized in the treatment of patients with severe burns. As burn injuries have a major impact in physical, psychosocial, and spiritual health, palliative care can be a strengthening component of integrated care.

AIM

To review and appraise the existing evidence about the integration of palliative care in burn intensive care units with respect to (1) the concept, model and design and (2) the benefits and outcomes of this integration.

DESIGN

A systematic review was conducted following PRISMA guidelines. Protocol registered with PROSPERO (CRD42018111676).

DATA SOURCES

Five electronic databases were searched (PubMed/NLM, Web of Science, MEDLINE/TR, Ovid, and CINAHL/EBSCO) until May 2019. A narrative synthesis of the findings was constructed. Hawker et al.'s tool was used for quality appraisal.

RESULTS

A total of 299 articles were identified, of which five were included for analysis involving a total of 7353 individuals. Findings suggest that there may be benefits from integrating palliative care in burn units, specifically in terms of patients' comfort, decision-making processes, and family care. Multidisciplinary teams may experience lower levels of burden as result of integrating palliative care in burn units.

CONCLUSION

This review reflects the challenging setting of burn intensive care units. Evidence from these articles suggests that the integration of palliative care in burn intensive care units improves patients' comfort, decision-making process, and family care. Further research is needed to better understand how the integration of palliative care in burn intensive care units may be fostered and to identify the outcomes of this integration.

Outcome and risk factors for death of elderly burn patients: a case series in Vietnam

The aim of this study is to investigate characteristics, outcome and risk factors for death among elderly burn patients. A retrospective study was conducted on 416 elderly (≥ 65 years old) burn patients admitted to the National Burn Hospital, Hanoi, Vietnam from 1/1/2016 to 31/12/2018. Data on demographics, comorbidity, burn severity, complications and mortality were recorded. Bivariate and multivariate analyses were conducted to determine independent risk factors for death. Results indicated that elderly burn patients accounted for 4.2% of total admitted patients with an average age of 74.7 ± 8.1 years old. Significantly higher burn surface area (12.4% vs. 7.3%; p < .001) and deep burn area (5.5% vs. 2.5%; p < .001) were seen in the female group when compared to the male group. Pre-existing medical conditions were recorded in 20.9% of patients, the highest proportion (13.2%) represented by cardiovascular disease followed by neurological and diabetic disease (8.7% and 7% respectively). Over half (51.5%) of the patients had suffered deep burn and 6.3% developed complications, the most common being multiple organ failure and pneumonia. Overall mortality rate was 9.9%. However, death rate was extremely high in patients with inhalation injury (92.9%), burn extent > 40% total body surface area (TBSA) and deep burn > 10% TBSA (61.2% and 62.5% respectively). Comorbidity was not an independent risk factor for death, unlike increased age, burn extent and presence of inhalation injury. In conclusion, we show that despite advances in management, severe burn and inhalation injury in the elderly remains a big challenge in Vietnam.
