[PMID: 39317549 DOI: 10.1016/j.burns.2024.07.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Revised: 06/25/2024] [Accepted: 07/03/2024] [Indexed: 09/26/2024]
Abstract
INTRODUCTION The Abbreviated Burn Severity Index (ABSI) by Tobiasen, which is commonly used to estimate the mortality risk of severely burned patients, calculates an additional point for the existence of full-thickness (third-degree) burns. [1] However, the score does not consider the extent of the body surface affected by third-degree burns. To understand whether there is a way to improve ABSI prediction power, this study aims to determine the influence of full-thickness burns on survival rates and how it affects the predictive precision of the ABSI. MATERIAL AND METHODS In this study, the statistical evaluation of 2538 patients collected prospectively in the context of the German Burn Registry was carried out. A linear regression analysis was carried out to show the prognostic relevance of full-thickness burns. Age, sex, total body surface area burned (TBSA), and the presence of inhalation injury were also observed as further influencing factors. RESULTS Among the 2538 patients meeting our inclusion criteria, full-thickness burns were found in 1233 patients. In patients with a TBSA below 20 %, the extent of full-thickness burns is not relevant to the prognosis in terms of survival probability (p = 0.124). With more than 20 % TBSA, the extent of third-degree burns is of significant relevance (p = 0.000). In patients without full-thickness burns and calculated ABSI values ≥ 12 the survival rate of 46 % was noticeably better than the predicted survival rate of < 10 % according to the ABSI Score, whereas the predicted survival rate in patients with third-degree burns (< 10 %), closely matched the observed survival rate of 11 %. CONCLUSION For patients with a TBSA < 20 %, the presence of full-thickness burns is not relevant for survival. In contrast to this observation, the percentage of full-thickness burns is of crucial prognostic importance for patients with a TBSA of > 20 %. By adjusting the ABSI and taking into account the exact percentage of third-degree burns, an improvement in the prognostic precision of the score could be achieved.

Abstract
BACKGROUND The percentage of total body surface area (%TBSA) burned and burn depth provide valuable information on burn injury severity. OBJECTIVE This study investigated the concordance between The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM) codes and expert burn clinicians in assessing burn injury severity. METHOD We conducted a retrospective population-based review of all patients who sustained a burn injury between July 1, 2009, and June 30, 2019, requiring admission into a specialist burn service across Australia and New Zealand. The %TBSA burned (including the percentage of full thickness burns) recorded by expert burn clinicians within the Burns Registry of Australia and New Zealand (BRANZ) were compared to ICD-10-AM coding. RESULTS 20,642 cases (71.5%) with ICD-10-AM code data were recorded. Overall, kappa scores (95% confidence interval [CI]) for burn size ranged from 0.64 (95% CI 0.63-0.66) to 0.86 (95% CI 0.78-0.94) indicating substantial to almost perfect agreement across all %TBSA groups. When stratified by depth, the lowest agreement was observed for < 10% TBSA and < 10% full thickness (kappa 0.03; 95% CI 0.02-0.04) and the highest agreement was observed for burns of ≥ 90% TBSA and ≥ 90% full thickness (kappa 0.72; 95% CI 0.58-0.85). CONCLUSION Overall, there was substantial agreement between the BRANZ and ICD-10-AM coded data for %TBSA classification. When %TBSA classification was stratified by burn depth, greater agreement was observed for larger and deeper burns compared with smaller and superficial burns. IMPLICATIONS Greater consistency in the classification of burns is needed.

Abstract
Burns in the elderly are a significant cause of morbidity and mortality. Frailty is an important indicator of patient health and physiologic reserve. Comorbidities and typical age-related changes significantly impact the outcomes of elderly burn patients and decisions made during their burn care. It is essential to have early and thorough discussions about the goals of care and rehabilitation plans. Physiologic changes that occur from aging cause slower wound healing and may make operative treatment more challenging, although techniques such as autographing, skin substitutes, and flaps may all play a role in treating this patient population.

Abstract
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 nonsurvivable 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 nonsurvivable 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 (eg, through surveys and/or interviews).

Abstract
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.

Abstract
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 (EoL) care discussions and decision-making following severe burn injury in Australian and New Zealand burn services. An online survey 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 of 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 toward certain aspects of EoL decision-making. Qualitative research could provide detailed insights into the varying perspectives held by clinicians.

Abstract
Older adults with an acute burn experience a high frequency of in-hospital mortality. However, traditional burn mortality prediction models are less accurate for older adults likely because they do not account for geriatric specific factors, such as frailty. This study aims to investigate the impact of frailty on in-hospital mortality in older adult burn patients. Patients ≥50 years of age with an acute burn diagnosis in the National Inpatient Sample (2016-2018) were included in the cohort. Three multivariable logistic regression models to predict in-hospital mortality were generated and compared. The models were 1) age and percent total body surface area, 2) age, percent total body surface area and the Elixhauser Comorbidity Index, and 3) age, percent total body surface area, and Hospital Frailty Risk Score. A total of 60,515 weighted discharges were included in the cohort. In-hospital mortality increased with age, as 3.3% of 50- to 64-year-olds, 5.3% of 65- to 74-year-olds, 6.6% of 75- to 84-year-olds, and 9.9% of ≥85-year-olds died during the acute burn admission (P < .001). The multivariable model that included Hospital Frailty Risk Score had a higher area under the receiver operating characteristics curve than the model with age and percent total body surface area (0.84 vs 0.79; P < .001) and the model with Elixhauser Comorbidity Index (0.84 vs 0.83; P = .013). Frailty improved prediction of in-hospital mortality for older adult acute burn patients and burn specialists should consider implementing a frailty instrument to evaluate older adults with an acute burn injury.

Abstract
BACKGROUND Burn is an overwhelming injury. The De Ritis ratio, defined as aspartate aminotransferase to alanine aminotransferase ratio, can be used to predict poor outcomes. We evaluated the risk factors, including the De Ritis ratio, associated with 1-year mortality after burn surgery. METHODS Patients who underwent burn surgery from 2009 to 2019 were retrospectively evaluated. Multivariate Cox regression analysis was conducted to evaluate the risk factors for 1-year mortality after burn surgery. Receiver operating characteristic (ROC) curve analysis of the De Ritis ratio was performed to predict postoperative 1-year mortality. Kaplan-Meier survival analysis was also conducted. Other postoperative outcomes, such as durations of hospital and intensive care unit stays, acute kidney injury, and major adverse cardiac events, were evaluated. RESULTS One-year mortality after burn surgery occurred in 247 (19.9%) of 1244 patients. The risk factors for 1-year mortality after burn surgery were the De Ritis ratio, age, American Society of Anesthesiologists physical status, diabetes mellitus, total body surface area burned, inhalation injury, serum creatinine level, and serum albumin level. The area under the ROC curve for the De Ritis ratio was 0.716 (optimal cutoff=1.9). The 1-year mortality rate after burn surgery was significantly higher in patients with a De Ritis ratio >1.9 than in those with a De Ritis ratio ≤1.9 (35.8% vs. 11.8%, P<0.001). The survival rate was significantly higher in patients with a De Ritis ratio ≤1.9 than in those with a De Ritis ratio >1.9 (log-rank test, P<0.001). Intensive care unit stay, acute kidney injury, and major adverse cardiac events were significantly higher in patients with a De Ritis ratio >1.9 than in those with a De Ritis ratio ≤1.9 (P=0.006, P<0.001, and P<0.001, respectively). CONCLUSIONS The preoperative De Ritis ratio was a risk factor for 1-year mortality after burn surgery. The De Ritis ratio >1.9 was significantly associated with an increased 1-year mortality after burn surgery. These findings emphasized the importance of identifying burn patients with an increased De Ritis ratio to reduce the mortality after burn surgery.

Abstract
BACKGROUND Burn injury in elderly patients can result in poor outcomes. Prognostic nutritional index (PNI) can predict the perioperative nutritional status and postoperative outcomes. We aim to evaluate the risk factors, including PNI, for one-year mortality after burn surgery in elderly patients. METHODS Burn patients aged ≥65 years were retrospectively included. PNI was calculated using the following equation: 10 × serum albumin level (g/dL) + 0.005 × total lymphocyte count (per mm3). Cox regression, receiver operating characteristic curve and Kaplan-Meier survival analyses were performed to evaluate the risk factors for postoperative one-year mortality. RESULTS Postoperative one-year mortality occurred in 71 (37.6%) of the 189 elderly burn patients. Risk factors for one-year mortality were PNI on postoperative day one (hazard ratio (HR) = 0.872; 95% CI = 0.812-0.936; p < 0.001), Sequential Organ Failure Assessment score (HR = 1.112; 95% CI = 1.005-1.230; p = 0.040), American Society of Anesthesiologists physical status (HR = 2.064; 95% CI = 1.211-3.517; p = 0.008), total body surface area burned (HR = 1.017; 95% CI = 1.003-1.032; p = 0.015) and preoperative serum creatinine level (HR = 1.386; 95% CI = 1.058-1.816; p = 0.018). The area under the curve of PNI for predicting one-year mortality after burn surgery was 0.774 (optimal cut-off value = 25.5). Patients with PNI ≤25.5 had a significantly lower one-year survival rate than those with PNI >25.5 (32.1% vs 75.9%, p < 0.001). CONCLUSIONS PNI on postoperative day one was associated with postoperative one-year mortality in elderly burn patients. The postoperative one-year survival rate was lower in patients with PNI ≤25.5 than in those with PNI >25.5. These findings indicate the importance of identifying elderly burn patients with low PNI, thereby reducing the mortality after burn surgery.

Abstract
PURPOSE To examine the associations between premorbid nutritional status and in-hospital mortality in severe burn patients according to age in Japan. METHODS We retrospectively extracted the data of 14,345 patients aged 18-84 years admitted for burns from April 1, 2014, to March 31, 2018, using the Japanese Diagnosis Procedure Combination database. The exclusion criteria were out-of-hospital cardiac arrest, death in the emergency room, readmission, and planned admission. We collected data on age, sex, height, weight, comorbidities, burn index, and mechanical ventilation use and performed age-stratified multilevel logistic regression analyses to estimate associations between premorbid body mass index (BMI) and in-hospital mortality. RESULTS We analyzed 2968 patients with a burn index ≥10, including 831 elderly aged 75-84 years. In patients aged 18-74 years, being underweight (BMI < 18.5) significantly decreased mortality (0.34 [0.15-0.77]; P = 0.010). In contrast, in patients aged 75-84 years, being underweight significantly increased mortality (2.11 [1.05-4.25]; P = 0.036). Being overweight (BMI >25) increased mortality in both age groups, but not significantly. CONCLUSIONS The results suggest that pre-morbidly underweight elderly patients aged 75-84 years with severe burns have high mortality risks. Further research is needed to identify optimal care strategies for this population.

Abstract
Background: Infection is the greatest cause of mortality in burn patients. As our population ages, the need to care for elderly burn patients will increase, and with it our understanding of how infection affects older patients with burn injuries. This article presents a review of the available literature on the effect of aging on the physiologic response to burns, of the known effects of infection in the elder population, and of the contribution of underlying medical comorbidities to the outcomes for the elderly burn patient. The potential for more serious outcomes from multi-drug resistance in the elder population is also discussed. Methods: This article is a review of the available literature on infection in elderly burn patients. A literature search was performed for key words: elderly; geriatric; burn; infection; comorbidity; multi-drug resistance; central line; urinary tract infection; and burn sepsis. Relevant findings were included in each section. Results: Pre-existing conditions are common in the elderly and contribute to a higher rate of development of pneumonia, cellulitis, urinary tract infection, central line infections, and burn wound infections. Specific data pertaining to infections in the elderly burn population are scarce or confined to single-center reports. Conclusions: Because of the inherent susceptibility of the elder population to infection because of pre-existing medical conditions, immunosenescence, and potential exposure via frequent interaction with the medical system, vigilance must be maintained for preventing and treating infection in elderly burn patients. More research is needed to define the risks and extent of this increasingly important issue.

Abstract
Cutaneous adverse drug reactions comprise a significant proportion of all adverse drug reactions. They may mimic other dermatologic or systemic illnesses and may cause significant morbidity or mortality. Seven morphologic groups encompass the most commonly encountered cutaneous drug reaction syndromes: exanthematous (maculopapular), dermatitic/eczematous, urticarial, pustular, blistering, purpuric, and erythrodermic. Drug reactions may have significant downstream consequences for the older individual.

Abstract
For older people (aged over 65 years), the risk of dying in a residential fire is
doubled compared to the general population. Obvious causes of death mainly
include smoke inhalation and burn injuries. That older people are more fragile
and have more concurrent diseases is inherent, but what is it that makes them
more vulnerable? It is known that the number of elderly people is increasing
globally and that the increased risk of death in fires can be explained, at
least in part, by physical and/or cognitive disabilities as well as
socioeconomic and behavioural factors. The possibility that medical illnesses
and an aging organism/tissues might explain this increased risk has not been
shown to the same extent. Therefore, this narrative literature review focuses on
medical and biological explanations. An initial search using the terms
‘elderly’, ‘fatal’, ‘residential’ and ‘fire’ yielded some interesting articles.
Using a broader snowball search also accepting grey literature, several
additional risk factors could be identified. Cardiovascular diseases, in
particular atherosclerotic heart disease, greatly increases the vulnerability
to, for example, carbon monoxide and probably also other asphyxiating gases.
Cardiovascular diseases and lack of physical fitness may also increase
vulnerability to heat. Burned elderly patients are also at a higher risk of
death than younger patients, but it is controversial whether it is age itself or
the pre-existing illnesses that come with age that increase the risk.
Immunosenescence, malnutrition and female gender are other risk factors for
poorer outcome after burns, all of which are common among older people. Elderly people have an increased risk of dying in house fires for several known
reasons. This review explores possible medical/biological explanations and finds
heart disease to be an important explanation.

Abstract
INTRODUCTION Although gender differences in morbidity and mortality have been measured in patients with moderate to severe burn injury, little attention has been directed at gender effects on health-related quality of life (HRQoL) following burn injury. The current study was therefore conducted to prospectively measure changes in HRQoL for males and females in a sample of burn patients. METHODS A total of 114 adults who received treatment at a statewide burns service for a sustained burns injury participated in this study. Instruments measuring generic health status (Short Form 36 Medical Outcomes Survey version 2), burn-specific HRQoL (Burns Specific Health Scale-Brief), psychological distress (Kessler Psychological Distress Scale) and alcohol use (Alcohol Use Disorders Identification Tool) were prospectively measured at 3, 6 and 12 months post-burn. RESULTS In the 12 months post-injury, female patients showed overall poorer physical (p=0.01) and mental health status (p<0.001), greater psychological distress (p<0.001), and greater difficulty with aspects of burn-specific HRQoL: body image (p<0.001), affect (p<0.001), interpersonal functioning (p=0.005), heat sensitivity (p=0.01) and treatment regime (p=0.01). While significant interaction effects suggested that female patients had more improvement in difficulties with treatment regime (p=0.007), female patients continued to report greater difficulty with multiple aspects of physical and psychosocial health status 12 months post-injury. CONCLUSION Even though demographic variables, injury characteristics and burn care interventions were similar across genders, following burn injury female patients reported greater impairments in generic and burn-specific HRQoL along with psychological morbidity, when compared to male patients. Urgent clinical and research attention utilising an evidence-based research framework, which incorporates the use of larger sample sizes, the use of validated instruments to measure appropriate outcomes, and a commitment to monitoring long-term care, can only improve burn-care.

Abstract
OBJECTIVE To develop a mathematical model of predicting mortality based on the admission characteristics of 6220 burn cases. METHODS Data on all the burn patients presenting to Institute of Burn Research, Southwest Hospital, Third Military Medical University from January of 1999 to December of 2008 were extracted from the departmental registry. The distributions of burn cases were scattered by principal component analysis. Univariate associations with mortality were identified and independent associations were derived from multivariate logistic regression analysis. Using variables independently and significantly associated with mortality, a mathematical model to predict mortality was developed using the support vector machine (SVM) model. The predicting ability of this model was evaluated and verified. RESULTS The overall mortality in this study was 1.8%. Univariate associations with mortality were identified and independent associations were derived from multivariate logistic regression analysis. Variables at admission independently associated with mortality were gender, age, total burn area, full thickness burn area, inhalation injury, shock, period before admission and others. The sensitivity and specificity of logistic model were 99.75% and 85.84% respectively, with an area under the receiver operating curve of 0.989 (95% CI: 0.979-1.000; p<0.01). The model correctly classified 99.50% of cases. The subsequently developed support vector machine (SVM) model correctly classified nearly 100% of test cases, which could not only predict adult group but also pediatric group, with pretty high robustness (92%-100%). CONCLUSION A mathematical model based on logistic regression and SVM could be used to predict the survival prognosis according to the admission characteristics.

Abstract
BACKGROUND The burn index (BI=full thickness total burn surface area [TBSA]+1/2 partial thickness TBSA) and prognostic burn index (PBI=BI+age) are clinically used particularly in Japan. However, few studies evaluated the validation of PBI with large sample size. We retrospectively investigated the relationships between PBI and mortality among burn patients using data from a nationwide database. METHODS Data of all burn patients with burn index ≥1 were extracted from the Japanese Diagnosis Procedure Combination (DPC) inpatient database from 1 July 2010 to 31 March 2013 (17,185 patients in 1044 hospitals). The primary endpoint was all-cause in-hospital mortality. RESULTS Overall in-hospital mortality was 5.9% (1011/17,185). Mortality increased significantly as the PBI increased (Mantel-Haenszel trend test, P<0.001). The area under the receiver operating characteristic curve for PBI was 0.90 (95%CI, 0.90-0.91), and a PBI above a threshold of 85 showed the highest association with in-hospital mortality. Logistic regression analysis showed that PBI≥85 (odds ratio (OR), 14.6; 95%CI, 12.1-17.6), inhalation injury with mechanical ventilation (OR, 13.0; 95%CI, 10.8-15.7), Charlson Comorbidity Index≥2 (OR, 1.8; 95%CI, 1.5-2.3), and male gender (OR, 1.5; 95%CI, 1.3-1.8) were significant independent risk factors for death. CONCLUSIONS Our study suggested that a PBI above a threshold of 85 was significantly associated with mortality. The PBI and mechanical ventilation were the most significant factors predicting in-hospital mortality, after adjustment for inhalation injury, comorbidity, and gender.

Abstract
BACKGROUND The elderly population is more likely to be affected by accidents, such as burns, compared to younger populations because of their diminished host defense. There is limited data about the outcomes of elderly burn patients requiring hospitalization. METHODS In this retrospective study, we assessed the epidemiology and outcomes of burn injuries in elderly patients (>60 years old) admitted to a burn unit of a tertiary medical center based on patient characteristics, type and extent of burns, treatment, hospital stay and mortality rates. RESULTS Forty-eight elderly burn patients among 870 burn patients during the study period were evaluated. Fire was the most common cause of burns (77.1%). Most of the burns involved more than 20% of total body surface area. Twenty-six (54.2%) patients died during hospitalization. Although burn surface area slightly and non-significantly increased in patients over 75 years, there was a significantly increased mortality rate in these patients. Multivariate linear regression analysis revealed burn area and age as independent associates of mortality. CONCLUSION Our data show a high mortality rate in elderly burn patients. Extensive burns and increased age seem to increase the mortality risk.

Abstract
Outcomes after burn have continued to improve over the last 70 years in all age groups including the elderly. However, concerns have been raised that survival gains have not been to the same magnitude in elderly patients compared to younger age groups. The aims of this study were to analyze the recent outcomes of elderly burn injured patients admitted to the Birmingham Burn Centre, compare data with a historical cohort and published data from other burn centres worldwide. A retrospective review was conducted of all patients ≥65 years of age, admitted to our centre with cutaneous burns, between 2004 and 2012. Data was compared to a previously published historical cohort (1999-2003). 228 patients were included. The observed mortality for the study group was 14.9%. The median age of the study group was 79 years, the male to female ratio was 1:1 and median Total Body Surface Area (TBSA) burned was 5%. The incidence of inhalation injury was 13%. Median length of stay per TBSA burned for survivors was 2.4 days/% TBSA. Mortality has improved in all burn size groups, but differences were highly statistically significant in the medium burn size group (10-20% TBSA, p≤0.001). Burn outcomes in the elderly have improved over the last decade. This reduction has been impacted by a reduction in overall injury severity but is also likely due to general improvements in burn care, improved infrastructure, implementation of clinical guidelines and increased multi-disciplinary support, including Geriatric physicians.

Abstract
Accurate prediction of mortality following burns is useful as an audit tool, and for providing treatment plan and resource allocation criteria. Common burn formulae (Ryan Score, Abbreviated Burn Severity Index (ABSI), classic and revised Baux) have not been compared with the standard Acute Physiology and Chronic Health Evaluation II (APACHEII) or re-validated in a severely (≥20% total burn surface area) burned population. Furthermore, the revised Baux (R-Baux) has been externally validated thoroughly only once and the pediatric Baux (P-Baux) has yet to be. Using 522 severely burned patients, we show that burn formulae (ABSI, Baux, revised Baux) outperform APACHEII among adults (AUROC increase p<0.001 adults; p>0.5 children). The Ryan Score performs well especially among the most at-risk populations (estimated mortality [90% CI] original versus current study: 33% [26-41%] versus 30.18% [24.25-36.86%] for Ryan Score 2; 87% [78-93%] versus 66.48% [51.31-78.87%] for Ryan Score 3). The R-Baux shows accurate discrimination (AUROC 0.908 [0.869-0.947]) and is well-calibrated. However, the ABSI and P-Baux, although showing high measures of discrimination (AUROC 0.826 [0.737-0.916] and 0.848 [0.758-0.938]) in children), exceedingly overestimates mortality, indicating poor calibration. We highlight challenges in designing and employing scores that are applicable to a wide range of populations.

Abstract
Advances in burn care have decreased mortality in the past 20 years, but affecting elderly mortality rates (>65 years) remain challenging. This study evaluates the impact of home caregiver support on elderly burn patients' mortality. The authors retrospectively reviewed patients aged 65 and older admitted to their burn center from July 1995 to October 2004. Patient demographics, Injury Severity Score, TBSA, and patients' primary caregiver were collected. The outcomes were mortality, disposition, and length of stay and these were evaluated using univariate and subsequently multivariate regression. Significance was calculated at P ≤ .05. A total of 112 patients were included in the analysis. The mean age was 76±8. Male patients constituted 47%, whereas 53% were female patients, and mean TBSA was 21±16%. Thirty patients' primary caregiver was a spouse, for 38 it was a child, and 44 had no caregiver. Fifty-eight patients survived (51.7%), and 54 patients died (48.3%). Only 21% of the survivors had a child as their primary caregiver; however, 48% of the nonsurvivors had a child as the primary caregiver (P ≤ 0.05). On multivariate analysis, age, TBSA, and child as primary caregiver were all independent predictors of mortality. Having a child as a caregiver provided the largest impact, with an odds ratio of 4.4 (95% confidence interval, 1.2-15.62; P = .02).

Abstract
Reference to the concept of comfort measures is growing in the nursing and medical literature; however, the concept of comfort measures is rarely defined. For the comfort work of nurses to be recognized, nurses must be able to identify and delineate the key attributes of comfort measures. A concept analysis using Rodgers' evolutionary method (2000) was undertaken with the goal of identifying the core attributes of comfort measures and thereby clarifying this concept. Health care literature was accessed from the CINAHL and PubMed databases. No restrictions were placed on publication dates. Four main themes of attributes for comfort measures were identified during the analysis. Comfort measures involve an active, strategic process including elements of "stepping in" and "stepping back," are both simple and complex, move from a physical to a holistic perspective and are a part of supportive care. The antecedents to comfort measures are comfort needs and the most common consequence of comfort measures is enhanced comfort. Although the concept of comfort measures is often associated with end-of-life care, this analysis suggests that comfort measures are appropriate for nursing care in all settings and should be increasingly considered in the clinical management of patients who are living with multiple, chronic comorbidities.

Abstract
INTRODUCTION The elderly are the fastest growing population segment, and particularly susceptible to burns. Predicting outcomes for these patients remains difficult. Our objective was to identify early predictors of mortality in elderly burn patients. METHODS Our Burn Center's prospective database was reviewed for burn patients 60+ treated in the past 10 years. Predictor variables were identified by correlative analysis and subsequently entered into a multivariate logistic regression analysis examining survival to discharge. RESULTS 203 patients of 1343 (15%) were eligible for analysis. The average age was 72 ± 10 (range 60-102) and the average total body surface area (TBSA) burned was 23 ± 18% (range 1-95). Age, TBSA, base deficit, pO(2), respiratory rate, Glasgow Coma Score (GCS), and Revised Trauma Score (RTS, based on systolic blood pressure, respiratory rate, and GCS) all correlated with mortality (p ≤0 .05). Using multiple logistic regression analysis, a model with age, TBSA and RTS was calculated, demonstrating: In this model, β(0) is a constant that equals -8.32. CONCLUSIONS Predicting outcomes in elderly burn patients is difficult. A model using age, TBSA, and RTS can, immediately upon patient arrival, help identify patients with decreased chances of survival, further guiding end-of-life decisions.

Abstract
BACKGROUND The aim of this study was to estimate the incidence of acute malnutrition and to identify predictors of case fatality among burn patients in the poorest South African province, Eastern Cape. METHODS This longitudinal follow-up study was conducted among consecutive burn patients admitted to Nelson Mandela Academic Hospital, Mthatha, South Africa, between 2006 and 2008. Patients were monitored and treated daily from admission to discharge. Outcomes were acute protein malnutrition and mortality. Patients' demography, total body surface area (TBSA) of the burn, cause of the burn, weight, height, location of the burn, hemoglobin, serum albumin, wound infection, and antibiotics after culture and sensitivity results were the potential predictors of in-hospital mortality. A Cox's proportional hazards model for the time to death was then used to identify independent predictors of mortality after adjusting for confounding factors. Kaplan-Meier survival curves were generated for each arm of exposure status. RESULTS In all, 67 patients (35 males, 59 children) were studied. The mean (range) age was 8±12 years (1 month to 59 years). The cumulative incidence of acute malnutrition was 62.0% (n=42): 46.3% (n=31) at admission and 15.7% (n=11) after 7 days of hospitalization. Incidence of mortality was 16.4% (n=11 with in-hospital acute malnutrition). The only significant and independent predictors of mortality were total body surface area (TBSA) burn>40% [hazard ratio (HR) 10.5, 95% confidence interval (CI) 1.7-63; P<0.01] and affected anterior trunk (HR 4.4, 95% CI 1.3-14.7; P=0.018). CONCLUSIONS Urgent prevention strategies of burns and evidence-based practice with early nutritional supplementation are needed to reduce high rates of malnutrition and mortality.

Abstract
The purpose of this study was to evaluate glucose control and clinical outcomes in diabetic burn intensive care unit (ICU) patients. The authors reviewed 462 civilian patients admitted to the burn ICU over 4 years. Exclusion criteria were age <18 years, admission because of skin infection, incomplete records, and military patients. Subjects were labeled as diabetic if they had a diagnosis of diabetes documented in their medical records. Otherwise, they were labeled as nondiabetic. Diabetic patients (n = 57) were compared with nondiabetic patients (n = 405). Admission glucose levels were obtained from chemistries. Point-of-care devices provided the remaining glucose values. While in the burn ICU, hyperglycemia for all patients was treated using intensive insulin therapy with a target blood glucose level of 80 to 110 mg/dl. Mann-Whitney U test, χ test, and multivariate regressions were used for statistical analysis (P ≤ .05). Diabetic patients were older (60 ± 15 vs 44 ± 17 years) with higher admission glucose (196 ± 81 vs 133 ± 52 mg/dl), mean glucose (147 ± 37 vs 122 ± 24 mg/dl), glucose variability (30 ± 11 vs 22 ± 11%), and fewer ICU-free days (18 ± 12 vs 20 ± 11). After multivariate regression analyses, age, injury severity score, TBSA, admission glucose, and mean glucose significantly affected the number of ventilator-free days, ICU-free days, and hospital-free days. Glucose variability was associated with hospital-free days only. Age, injury severity score, and TBSA significantly influenced mortality, whereas a preexisting diagnosis of diabetes was not associated with any clinical outcomes. Admission blood glucose is higher, and blood glucose is more difficult to control in diabetic burn ICU patients. A preexisting diagnosis of diabetes does not influence clinical outcomes in critically ill burn patients.

Abstract
The percentage of total body surface area burnt (%TBSA) is a critical measure of burn injury severity and a key predictor of burn injury outcome. This study evaluated the level of agreement between four sources of %TBSA using 120 cases identified through the Victorian State Trauma Registry. Expert clinician, ICD-10-AM, Abbreviated Injury Scale, and burns registry coding were compared using measures of agreement. There was near-perfect agreement (weighted Kappa statistic 0.81–1) between all sources of data, suggesting that ICD-10-AM is a valid source of %TBSA and use of ICD-10-AM codes could reduce the resource used by trauma and burns registries capturing this information.

Influence of race and neighborhood on the risk for and outcomes of burns in the elderly in North Carolina. Burns 2011; 37:762-9.

Abstract
Risk factors for mortality and length of hospital stay in elderly burn patients are well established, but the influence of race and socioeconomic status has not been evaluated. This study evaluates the effect of neighborhood level socioeconomic indicators on burns risk, and determines whether race and neighborhood influence burn injury outcomes in the elderly. Data from the North Carolina Jaycee Burn Center was linked to United States Census Bureau block group socioeconomic data. The odds of death and increased length of hospital stay for European-Americans and Minorities were determined using logistic regression. Rates of burn were determined using Poisson regression, and multilevel modeling was used to evaluate the influence of neighborhood on outcomes. No significant differences in mortality were observed between European-American and Minority patients in individual (Minority OR 0.71; p=0.3200) and multilevel (0.72; p=0.4020) models. Minorities had significantly higher odds of increased length of hospital stay in individual (2.05; p=0.0020) and multilevel (2.55; 0.037) models. High proportions of rural households (RR=1.39; p=0.0010) and poverty (1.26; p<0.0001) were significantly associated with increased risk of burn. Additional investigation using larger databases will allow further elucidation of the contextual effects of socioeconomic status on burn in the elderly.

Abstract
Prediction of outcome for patients with major thermal injury is important to inform clinical decision making, alleviate individual suffering and improve hospital resource allocation. Age and burn size are widely accepted as the two largest contributors of mortality amongst burns patients. The APACHE (Acute Physiology and Chronic Health Evaluation) III-j score, which incorporates patient age, is also useful for mortality prediction, of intensive care populations. Validation for the burns specific cohort is unclear. A retrospective cohort study was performed on patients admitted to the Intensive Care Unit (ICU) via the Victorian Adult Burns Service (VABS), to compare observed mortality with burns specific markers of illness severity and APACHE III-j score. Our primary aim was to develop a mortality prediction tool for the burns population. Between January 1, 2002 and December 31, 2008, 228 patients were admitted to the ICU at The Alfred with acute burns. The mean age was 45.6 years and 81% (n=184) were male. Patients had severe injuries: the average percent TBSA (total body surface area) was 28% (IQR 10-40) and percent FTSA (full thickness surface area) was 18% (IQR 10-25). 86% (n=197) had airway involvement. Overall mortality in the 7-year period was 12% (n=27). Non-survivors were older, had larger and deeper burns, a higher incidence of deliberate self-harm, higher APACHE III-j scores and spent less time in hospital (but similar time in ICU), compared with survivors. Independent risk factors for death were percent FTSA (OR 1.03, 95% CI 1.01-1.05, p=0.01) and APACHE III-j score (OR 1.04, 95% CI 1.02-1.07, p<0.001). Mortality prediction based on both of these variables in combination was more specific than either individual variable alone (AUROC 0.85, 95% CI 0.79-0.92). Likelihood of death for patients with severe thermal injury can be predicted with accuracy from APACHE III-j score and percent FTSA. Prospective validation of our model on different burn populations is necessary.

Body surface area prediction in normal, hypermuscular, and obese mice. J Surg Res 2008; 153:326-31.

Abstract
BACKGROUND Accurate determination of body surface area (BSA) in experimental animals is essential for modeling effects of burn injury or drug metabolism. Two-dimensional surface area is related to three-dimensional body volume, which in turn can be estimated from body mass. The Meeh equation relates body surface area to the two-thirds power of body mass, through a constant, k, which must be determined empirically by species and size. We found older values of k overestimated BSA in certain mice; thus we determined empirically k for various strains of normal, obese, and hypermuscular mice. MATERIALS AND METHODS BSA was computed from digitally scanned pelts and nonlinear regression analysis was used to determine the best-fit k. RESULTS The empirically determined k for C57BL/6J mice of 9.82 was not significantly different from other inbred and outbred mouse strains of normal body composition. However, mean k of the nearly spheroid, obese lepr(db/db) mice (k = 8.29) was significantly lower than for normals, as were values for dumbbell-shaped, hypermuscular mice with either targeted deletion of the myostatin gene (Mstn) (k = 8.48) or with skeletal muscle specific expression of a dominant negative myostatin receptor (Acvr2b) (k = 8.80). CONCLUSIONS Hypermuscular and obese mice differ substantially from normals in shape and density, resulting in considerably altered k values. This suggests Meeh constants should be determined empirically for animals of altered body composition. Use of these new, improved Meeh constants will allow greater accuracy in experimental models of burn injury and pharmacokinetics.
