The association between body mass index and physical function in adult burn survivors: A Burn Model System National Database study. Burns 2024:S0305-4179(24)00188-8. [PMID: 38918151 DOI: 10.1016/j.burns.2024.06.003] [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: 01/25/2024] [Revised: 05/18/2024] [Accepted: 06/11/2024] [Indexed: 06/27/2024]
Abstract
INTRODUCTION An area of rehabilitation research in burns is the impact of co-morbidities on disease trajectory. Obesity is a comorbidity of increasing public health concern, but its role remains controversial regarding burn injury and physical recovery. Our aim was to evaluate the association between body mass index (BMI) categories as a measure of obesity at discharge and self-reported physical function (PF) during recovery of adult burn survivors. METHODS This is a retrospective study on data collected by four major US burn centers, which contribute to the Burn Model System National Database. The data included BMI obtained at hospital discharge and self-reported PF-mobility, using the PROMIS measures assessed at 6, 12, and 24 months after burn. Subjects were classified into weight status categories based on BMI: underweight (BMI <18.5), normal weight (18.5 ≤ BMI <25), overweight (25 ≤ BMI <30), obesity class 1 (30 ≤ BMI <35), obesity class 2 (35 ≤ BMI <40), and obesity class 3 (BMI ≥40). Mixed-effects linear regression models were used to assess the association between BMI categories and PF scores over time, adjusted for patient and injury characteristics. RESULTS A total of 496 adult burn patients aged 47 ± 16 years were included, with mean total body surface area (TBSA) burned of 18 ± 19 % and mean BMI at discharge of 28 ± 7 kg/m2. PROMIS PF scores significantly improved over time in the recovery phase after burn (time effect, p < 0.001). Compared to overweight burn patients, normal-underweights exhibited lower PF score by an average of 4.06 units (p = 0.001) but scores increased linearly by an estimated 0.17 units per month (p = 0.01) over the 24 months after discharge. Similarly, compared to overweight burn patients, class 1 obese reported lower PF score by a mean 2.67 units (p = 0.07) but PF increased linearly by 0.15 units per month (p = 0.07) over the 24 months after discharge. These findings were independent of the effects of age at discharge, sex, TBSA burned, and hand and leg burn. CONCLUSION Being overweight was associated with improved and faster recovery of PF scores compared to normal, underweight, and obese burn patients during long-term recovery. Hence, our data suggests that long-term recovery and restoration of PF in adult burn survivors is not compromised by a small excess in body weight.

[PMID: 37827936 DOI: 10.1016/j.burns.2023.06.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 06/02/2023] [Accepted: 06/20/2023] [Indexed: 10/14/2023]
Abstract
OBJECTIVES Current evidence on how the use of bromelain-based enzymatic debridement techniques (NexoBrid™) affect patient coagulation is limited. A single patient case report [1] suggests that a patient with 15% total body surface area (TBSA) burn developed decreased coagulation activity following debridement with NexoBrid™ enzymatic debridement (ED). Regional Burns Centres in the United Kingdom may be reluctant to use ED, particularly in larger burns, citing concerns regarding coagulation. At our centre we have routinely used ED on deep partial thickness burns since 2017 including on patients with burns over 15% TBSA. This study aims to investigate whether there is a significant disruption in coagulation in patients undergoing ED with burns > 15% TBSA or admitted to intensive care compared to the standard of care (SOC) which is surgical debridement in theatre. METHODS This single-centre retrospective study includes all patients with a burn treated with ED at Pinderfields General Hospital Regional Burns Centre intensive care unit (ITU) from 2017 to 2020. Patients were matched to those treated with SOC at the same centre by age, % TBSA burn and presence of inhalational injury. These parameters correlate with the Baux score [9]. Percentage of burn debrided was matched as closely as possible, with coagulation profiles and platelet count taken the day before, the day of and three days following surgery. RESULTS Thirty-one patients were treated with ED in the intensive care unit between 2017 and 2020. Four patients were excluded due to insufficient records and one patient was anti-coagulated. Twenty-six patients were included and matched as described above. Average age of patients receiving ED was 44 years, the same in the matched group. Average TBSA burn is 35.5% (35.8% in matched group). No statistically significant difference in coagulation was seen between patients undergoing ED compared to SOC when considering prothrombin time (PT), activated partial thromboplastin time (aPTT) and platelet count. Both groups slightly breached the upper limit of normal on day 2 post ED and SOC. There was a slight breach of the lower limit of the average platelet count on day 2 post-ED which was neither statistically nor clinically significant. CONCLUSIONS Large burns are associated with coagulation abnormalities, therefore isolating a single variable in this cohort is challenging. However, this study found no significant change following ED use when compared to SOC and therefore no convincing evidence that ED is associated with coagulation abnormalities. This study represents one of the largest focusing on coagulation abnormalities following the use of ED, as the current literature is limited. Our study suggests that concerns regarding coagulation abnormalities should not prevent patients with large, deep partial thickness burns or full thickness burns being treated with ED.

Abstract
BACKGROUND AND OBJECTIVES Burn injuries range from minor medical issues to severe, life-threatening conditions. The severity and location of the burn dictate its treatment; while minor burns might be treatable at home, severe burns necessitate medical intervention, sometimes in specialized burn centers with extended follow-up care. This study aims to leverage artificial intelligence (AI)/machine learning (ML) to forecast potential adverse effects in burn patients. METHODS This retrospective analysis considered burn patients admitted to Chi Mei Medical Center from 2010 to 2019. The study employed 14 features, comprising supplementary information like prior comorbidities and laboratory results, for building models for predicting graft surgery, a prolonged hospital stay, and overall adverse effects. Overall, 70% of the data set trained the AI models, with the remaining 30% reserved for testing. Three ML algorithms of random forest, LightGBM, and logistic regression were employed with evaluation metrics of accuracy, sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC). RESULTS In this research, out of 224 patients assessed, the random forest model yielded the highest AUC for predictions related to prolonged hospital stays (>14 days) at 81.1%, followed by the XGBoost (79.9%) and LightGBM (79.5%) models. Besides, the random forest model of the need for a skin graft showed the highest AUC (78.8%), while the random forest model and XGBoost model of the occurrence of adverse complications both demonstrated the highest AUC (87.2%) as well. Based on the best models with the highest AUC values, an AI prediction system is designed and integrated into hospital information systems to assist physicians in the decision-making process. CONCLUSIONS AI techniques showcased exceptional capabilities for predicting a prolonged hospital stay, the need for a skin graft, and the occurrence of overall adverse complications for burn patients. The insights from our study fuel optimism for the inception of a novel predictive model that can seamlessly meld with hospital information systems, enhancing clinical decisions and bolstering physician-patient dialogues.

Abstract
Frailty can increase the risk of dying after suffering a severe injury. The Modified Frailty Index (MFI) was developed by the American College of Surgeons National Surgical Quality Improvement Program to determine the impact of frailty on outcomes. Our aim was to correlate frailty with survival following a burn injury using the 11-item and 5-item MFI. We performed a secondary analysis of the Transfusion Requirement in Burn Care Evaluation (TRIBE) study. Data including, age, gender, medical history, extent and severity of burn injury, inhalation injury and discharge disposition was collected from the TRIBE database. The 11-item MFI (MFI-11) and 5-item MFI (MFI-5) scores were calculated for all patients in the TRIBE database. The TRIBE database included 347 patients. The mean age of subjects was 43 ± 17 years. Mean total body surface area burn (TBSA) was 38 ± 18%, and 23% had inhalation injury. Multivariate logistic regression analysis determined that both MFI-5 (OR 1.86; 95% CI: 1.11-3.11; P-value .02) and MFI-11 (OR 1.83; 95% CI: 1.18-2.8; P-value .007) were independent predictors for mortality. Additionally, MFI-11 scores that are >1 were independently associated with a markedly increased risk of dying after a burn injury (OR 2.91; 95% CI: 1.1-7.7; P-value .03). The MFI can be used to identify vulnerable burn injured patients who are at high risk of dying.

Variation of the SOFA score and mortality in patients with severe burns: A cohort study. Burns 2023; 49:34-41. [PMID: 36202683 DOI: 10.1016/j.burns.2022.09.004] [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: 04/22/2022] [Revised: 08/30/2022] [Accepted: 09/13/2022] [Indexed: 01/06/2023]
Abstract
Multiple organ failure (MOF) is the leading cause of death in patients with burns requiring ICU admission. Quantifying the evolution of MOF, with the SOFA score, over the first few days after a severe burn may provide useful prognostic information. This retrospective cohort study aimed at evaluating the association between the evolution of the SOFA score between day 0 and day 3 and in-hospital mortality. All patients admitted for severe burns at the burn ICU of the Tours University Hospital between 2017 and 2020 and who stayed 3 days or more were included. Severe burns included: total body surface area burned (TBSA) ≥ 20 % or burns of any surface associated with one or more of the following items: (1) organ failure, (2) clinically significant smoke inhalation and/or cyanide poisoning, (3) severe preexisting comorbidities, (4) complex and specialized burn wound care. DeltaSOFA was defined as day 3 minus day 0 SOFA. One hundred and thirty-six patients were included. Median age was 52 years (38-70), median TBSA burned was 24 % (20-38), median day 0 SOFA was 2 (0-4) and median day 3 SOFA was 1 (0-5). In-hospital mortality was 10 %. There was a significant association between deltaSOFA and mortality that persisted after adjustment for age and TBSA (HR 1.37, 95 %CI 1.09-1.72, p < 0.01). Area under the receiver operating characteristics curve for the prediction of mortality by day 0 SOFA and deltaSOFA were 0.79 (95 %CI 0.69-0.89) and 0.83 (95 %CI 0.70-0.95) respectively. After exclusion of patients with TBSA burned< 15 %, deltaSOFA remained independently associated with mortality (HR 1.42 95 %CI 1.09-1.85, p < 0.01). In addition, SOFA variations allowed the identification of subgroups of patients with either very low or very high mortality. In patients with severe burns, SOFA score evolution between day 0 and day 3 may be useful for individualized medical and ethical decisions. Further multicenter studies are required to corroborate the present results.

Abstract
Burn severity is determined by total body surface area affected, temperature of source, and duration of exposure. Patients with impaired mobility are less capable of avoiding hazards and escaping traumatic injuries. Additionally, patients with impaired mobility frequently suffer from other comorbid conditions and have specialized needs, which can complicate their acute treatment. This study was a retrospective electronic medical records review of all adult patients, aged 18 years and older with a preexisting mobility impairment, admitted as inpatients to a single burn center for treatment of burn-related injuries from January 1, 2009, to December 31, 2019. The 10-year review of 1520 adult burn admissions meeting the initial criteria of inpatient admission and burn injury revealed 174 patients with documentation supporting preexisting functional mobility impairment (11%). Surprisingly, patients' overall lengths of stays were consistent with all burn populations at 0.81 days per % TBSA, with the average length of stay being 6.7 days. The demographic data were consistent with national burn registry data as male, Caucasian, and older, with mean age of 61.1 years. Demographic data and details of hospital course focusing on treatment, complications, and outcomes were extracted and analyzed. There is a paucity of literature describing the needs of this unique burn population. Burn-injured patients with preexisting mobility impairments suffer from similar mechanisms of injury. By identifying attributes unique to this population, we hope to develop specialized prevention education and treatment protocols.

Abstract
BACKGROUND It is important to determine the severity of inhalation injury in severely burned patients. The oxygenation index PaO2/FiO2(PF) ratio is a key clinical indicator of inhalation injury. Sequential organ failure assessment (SOFA) is developed to assess the acute incidence of critical illness in the population. We hope to provide an assessment of survival or prognostic factor for severely burned patients with inhalation injury based on the respiratory SOFA score. METHODS This is a retrospective cohort study of all admissions to Department of Burn and Plastic Surgery at West China Hospital of Sichuan University from July 2010 to March 2021. Data was analyzed using Cox regression models to determine significant predictors of mortality. Survival analysis with time to death event was performed using the Kaplan-Meier survival curve with the log-rank test. All potential risk factors were considered independent variables, while survival was considered the risk dependent variable. RESULTS One hundred eighteen severe burn patients with inhalation injury who met the inclusion and exclusion criteria were admitted, including men accounted for 76.3%. The mean age and length of stay were 45.9 (14.8) years and 44.3 (38.4) days. Flame burns are the main etiology of burn (74.6%). Patients with the respiratory SOFA score greater than 2 have undergone mechanical ventilation. Univariate Kaplan-Meier analysis identified age, total body surface area burned (TBSA), ICU admission and the respiratory SOFA score as significant factors on survival. Cox regression analysis showed that TBSA and the respiratory SOFA score were associated with patient survival (p < 0.001). In some patients with severe burns and inhalation damage, the survival probability drops to less than 10% (TBSA greater than 80%: 8.9% and respiratory SOFA score greater than 2: 5.6%). This study statistically found that the TBSA with the respiratory SOFA score model (AUROC: 0.955) and the rBaux score (AUROC: 0.927) had similar predictive value (p = 0.175). CONCLUSION The study indicates that a high respiratory system SOFA score was identified as a strong and independent predictor of severely burned patients with inhalation injury during hospitalization. When combined with TBSA, the respiratory SOFA scores can dynamically assess the severity of the patient's lung injury and improve the predictive level.

Association of age with perioperative morbidity among patients undergoing surgical management of minor burns. Front Surg 2023; 10:1131293. [PMID: 36923377 PMCID: PMC10008887 DOI: 10.3389/fsurg.2023.1131293] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Accepted: 02/13/2023] [Indexed: 03/01/2023] Open
Abstract
Introduction Burn injuries are associated with significant morbidity, often necessitating surgical management. Older patients are more prone to burns and more vulnerable to complications following major burns. While the relationship between senescence and major burns has already been thoroughly investigated, the role of age in minor burns remains unclear. To better understand differences between elderly and younger patients with predominantly minor burns, we analyzed a multi-institutional database. Methods We reviewed the 2008-2020 ACS-NSQIP database to identify patients who had suffered burns according to ICD coding and underwent initial burn surgery. Results We found 460 patients, of which 283 (62%) were male and 177 (38%) were female. The mean age of the study cohort was 46 ± 17 years, with nearly one-fourth (n = 108; 23%) of all patients being aged ≥60 years. While the majority (n = 293; 64%) suffered from third-degree burns, 22% (n = 99) and 15% (n = 68) were diagnosed with second-degree burns and unspecified burns, respectively. An average operation time of 46 min, a low mortality rate of 0.2% (n = 1), a short mean length of hospital stay (1 day), and an equal distribution of in- and outpatient care (51%, n = 234 and 49%, n = 226, respectively) indicated that the vast majority of patients suffered from minor burns. Patients aged ≥60 years showed a significantly prolonged length of hospital stay (p<0.0001) and were significantly more prone to non-home discharge (p<0.0001). In univariate analysis, advanced age was found to be a predictor of surgical complications (p = 0.001) and medical complications (p = 0.0007). Elevated levels of blood urea nitrogen (p>0.0001), creatinine (p>0.0001), white blood cell count (p=0.02), partial thromboplastin time (p = 0.004), and lower levels of albumin (p = 0.0009) and hematocrit (p>0.0001) were identified as risk factors for the occurrence of any complication. Further, complications were more frequent among patients with lower body burns. Discussion In conclusion, patients ≥60 years undergoing surgery for predominantly minor burns experienced significantly more complications. Minor lower body burns correlated with worse outcomes and a higher incidence of adverse events. Decreased levels of serum albumin and hematocrit and elevated values of blood urea nitrogen, creatinine, white blood count, and partial thromboplastin time were identified as predictive risk factors for complications.

[PMID: 36261833 PMCID: PMC9583545 DOI: 10.1186/s12911-022-02013-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 09/16/2022] [Accepted: 10/04/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Toxic epidermal necrolysis (TEN) patients require multi-directional and multi-disciplinary treatment. In most cases, they are hospitalised at intensive care units and require multi-directional, burn-complication preventive care. Choosing the most appropriate treatment option might be troublesome even when predicting scores are used. SCORTEN is the most renowned prognostic score for TEN patients, however, there are some data indicating that the accuracy of this test may be limited. The credibility of not just the predicted mortality risk, but also componential laboratory results and clinical features subject to debate. The aim of this study was to evaluate the efficacy and credibility of SCORTEN in clinical practice, on proprietary material. METHODS A retrospective analysis of 35 patients with diagnosed in histopathology TEN was performed. The inclusion criteria were as follows: day of submission before 5th day from the onset of the symptoms, full protocol of plasmaphereses and IVIGs according to our scheme. Our protocol includes cycle of plasmapheresis with frozen fresh plasma twice daily for the first 2 days following admission, and once daily for the subsequent 5 to 7 days. IVIGs were administered after the first two sessions of plasmapheresis, for 4 to 7 days. The dosage was calculated according to body weight, at 0.4 to 0.5 g/kg per dose. RESULTS The sensitivity of SCORTEN for the analysed cohort was 100%, with a specificity of 24%. The estimated death was 41,9%, while the actual death rates were 12,5%. Our protocol improved the survival, OR = 26,57, RR = 6,34, p = 0,022. Decrease in mortality was caused by a combined treatment protocol we use- plasmaphereses with IVIGs. No independent risk factor was significant in death evaluation. CONCLUSION Our data suggest that the scoring system for predicting death among TEN patients are reliable when they are high. New prognostic factors should be found to improve the evaluation of patients with low SCORTEN.

Abstract
Advances in burn care have improved patient outcomes, and independently validated indices and predictors of burn outcomes warrant re-evaluation. The purpose of this study is to consolidate predictors of burn outcomes and determine the factors that significantly contribute to length-of-stay (LOS) and mortality. A retrospective review was conducted of all burn patients (n=5778) admitted to a quaternary provincial burn unit from 1973 to 2017. Our inclusion criteria yielded 4622 independent cases. Multivariate linear and logistic regression models were generated, and area-under-receiver-operator-curve (AUROC) analysis was performed. Burn predictors included %TBSA, Baux (classic and revised) index, Abbreviated Burn Severity Index (ABSI), and Ryan score. Primary outcomes were mortality and LOS. Multivariate logistic regression for mortality showed the Baux index to be the best predictor for mortality (OR=1.11, p<0.001). The AUROC for Baux index was 0.95. With regards to LOS, ABSI was the best predictor for LOS (p<0.001). ICU stay, ventilator use, alcoholism, age, significantly associated with increased LOS. Interestingly, hypertension had a protective effect for LOS (p<0.01) and trended towards a protective effect in mortality. Lethal score 50% (LS50) improved over the study period. The regressions show that burn mortality and LOS are best predicted with the Baux index and ABSI, respectively. Hypertension may have a protective effect on burn outcomes and may be attributed to increased perfusion to the periphery. These predictive scores are useful in determining institutional outcomes in burn surgery. Objective benchmarking of improvement in burn care outcomes can be established using LS50 trends.

Abstract
OBJECTIVES To investigate whether the Charlson Comorbidity Index (CCI) predicted short-term and long-term mortality in patients with a bloodstream infection visiting the emergency department (ED) and compare it to the often-validated National Early Warning Score (NEWS). DESIGN A retrospective cohort study. SETTING A tertiary hospital in the Netherlands. PARTICIPANTS Adult patients attending the ED with a blood culture-proven infection between 2012 and 2017 were included. We collected the comorbidities from the CCI and the vital signs from the NEWS. MAIN OUTCOMES Short-term mortality (30-day) and long-term mortality (1 year). We assessed the predictive performance by discrimination, expressed as the area under the curve (AUC). RESULTS We included 1039 patients with a blood culture-proven infection. Mortality was 10.4% within 30 days and 27.8% within 1 year. On average patients had two comorbidities (ranging from 0 to 6). Highly prevalent comorbidities were malignancy (30.2%) and diabetes mellitus (20.5%). The predictive performance of the CCI was highest for 1-year mortality (AUC 0.696 (95%CI) (0.660 to 0.732)) and better compared with the NEWS (AUC (95% CI) 0.594 (0.555 to 0.632)). For prediction of 30-day mortality, the NEWS was superior (AUC (95% CI) 0.706 (0.656 to 0.756)) to the comorbidities of the CCI (AUC (95% CI) 0.568 (0.507 to 0.628)). CONCLUSIONS We found that presenting comorbidity (ie, the CCI) is most useful to prognosticate long-term outcome in patients with bloodstream infection in the ED. Short-term mortality is more accurately predicted by deviating vital signs (ie, the NEWS).

Abstract
INTRODUCTION Reviewing the profile of patients admitted at the Burns Intensive Care Unit at São Paulo Hospital - UNIFESP, as well as the available literature, it becomes evident the need for tools able to predict those patients' outcomes. Distinct score models are used in different health centers, not only as prognostic models, but also as research and quality control tools. Amongst these prognostic scores, there are two strands, the burns specific scores - which consider the injury's characteristics - and the general critical patient's scores. OBJECTIVE This study aims to analyze the differences and tendencies in mortality prediction of two broadly used scores when applied to São Paulo Hospital's Burns Intensive Care Unit patients, ABSI - burns specific score - and SAPS 3 - general score for critical patients. METHODS This is an individual, observational, retrospective and comparative study, developed with medical records review. Both scores were applied to every patient admitted at São Paulo Hospital's Burns Intensive Care Unit from 2011 to 2016. Statistical analyses used the non-parametric test of Kolmogorov-Smirnov, a p-value <0.05 was considered significant. RESULTS 122 patients were included, the average age was 34,4 years old. 70,5% of patients were male and 49% had a total body surface area burned of 20%. 27% of the patients died. Statistical analyses do not show significant differences between ABSI and SAPS3 mortality predictions for burns patients at this health center. CONCLUSION The study evidences that SAPS 3 score, frequently used at general Intensive Care Units, has a similar performance to ABSI score, which is specific for burns populations. ABSI score is easier to implement, as it is simpler and able to show instant results.

Abstract
According to the World Health Organization (WHO), it is estimated that each year approximately 11 million people suffer from burn wounds, 180,000 of whom die because of such injuries. Regardless of the factors causing burns, these are complicated wounds that are difficult to heal and are associated with high mortality rates. Medical care of a burn patient requires a lot of commitment, experience, and multidirectional management, including surgical activities and widely understood pharmacological approaches. This paper aims to comprehensively review the current literature concerning burn wounds, including classification of burns, complications, medical care, and pharmacological treatment. We also overviewed the dressings (with an emphasis on the newest innovations in this field) that are currently used in medical practice to heal wounds.

Abstract
Advances in burn care continues to improve survival rates and patient outcomes. There are several burn prognostic tools used to predict mortality and outcomes; however, none include patient comorbidities. We used the American Society of Anesthesiologists physical status score as a surrogate measure for comorbidities, and evaluated its role in predicting mortality and outcomes in adult burn patients undergoing surgery. A retrospective analysis was performed on data collected from a single burn center in the United States, which was comprised of 183 patients. We evaluated the American Society of Anesthesiologists physical status score as an independent predictor of mortality and outcomes, including intensive care unit (ICU) length of stay (LOS), hospital LOS, mechanical ventilator (MV) days, and complications. We compared the American Society of Anesthesiologists physical status score to other prognostic models which included the revised Baux score, Belgian Outcome in Burn Injury, and the Abbreviated Burn Severity Index. Our results demonstrated that the revised Baux and American Society of Anesthesiologists physical status scores could be used to determine the mortality risk in adult burn patients. The revised Baux was the best predictor of mortality, ICU LOS, and MV days, while the Abbreviated Burn Severity Index was the best predictor of total LOS.

Abstract
Introduction Burns are common in developing countries and place a large burden on the medical and social care systems. However, information about management and outcomes from such countries is scarce. The purpose of this study was to analyze the epidemiology and main factors related to the mortality in severely burned patients at the Hospital Universitario San Vicente Fundación in Medellín, Colombia. Methods An observational retrospective cohort study was conducted. To establish prognostic factors associated with mortality, we analyzed variables such as age, sex, burned surface, and degree of burn, among others. Demographic, clinic, and management features as well as complications and factors associated with mortality were analyzed using logistic regression. Results 4516 clinical histories were reviewed, 225 were included in the study. 76.9% were men, with a median age of 35 years; 64.9% were fire burns. The median burned body surface area was 42%. There were inhalation injuries in 135 patients and ocular in 106 patients. The main complication was infection followed by rhabdomyolysis. The overall hospital stay was 27 days, and the median length of stay at the intensive care unit was 7 days with in-hospital mortality of 30.7%. The variables associated with mortality were age, burned body surface area, degree of burn, and kidney injury. Surgical intervention was protective. Conclusions Severely burned patients in our hospital have similar outcomes and, in some cases, better outcomes than those reported in the literature in countries with similar characteristics, and we have seen that in the last years, there has been a better experience in the management of these patients. Elderly, extension, and depth of burnt tissue are markers of poor outcomes. Early surgery and intubation have shown better outcomes, probably due to infection control and removal of necrotic tissue, airway management, and ventilatory support for metabolic and hemodynamic derangement.

Abstract
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.

Abstract
Background Sepsis is a leading cause of mortality among severe burns. This study was conducted to investigate the predictive role of C-reactive protein-to-albumin ratio (CAR) for sepsis and prognosis in severe burns. Methods Patients with severe burn injuries from 2013 to 2017 were enrolled and divided into septic and nonseptic groups based on the presence of sepsis within 30 days postburn. Independent risk factors for sepsis were performed by the univariate and multivariate logistic regression analyses. The association between CAR level at admission and postburn 30-day mortality was designed via the Kaplan–Meier method. Results Of all the 196 enrolled patients, 83 patients developed sepsis within 30 days postburn injury, with an incidence of 42.3%. TBSA percentage (OR: 1.65, 95% CI: 1.17-2.32, P = 0.014) and CAR at admission (OR: 2.25, 95% CI: 1.33-3.56, P = 0.009) were the two independent risk factors for sepsis in severe burns by the multivariate logistic regression analysis. A higher CAR level (≥1.66) at admission was associated with a lower postburn 30-day survival rate (P = 0.005). Conclusions The CAR level at admission was an independent risk factor for sepsis and prognosis in severe burns.

Abstract
Thermal injury is often associated with a proinflammatory state resulting in serious complications. After a burn, the innate immune system is activated with subsequent immune cell infiltration and cytokine production. Although the innate immune response is typically beneficial, an excessive activation leads to cytokine storms, multiple organ failure, and even death. This overwhelming immune response is regulated by damage-associated molecular patterns (DAMPs). DAMPs are endogenous molecules that are actively secreted by immune cells or passively released by dead or dying cells that can bind to pathogen recognition receptors in immune and nonimmune cells. Recent studies involving animal models along with human studies have drawn great attention to the possible pathological role of DAMPs as an immune consequence of thermal injury. In this review, we outline DAMPs and their function in thermal injury, shedding light on the mechanism of sterile inflammation during tissue injury and identifying new immune targets for treating thermal injury.

Abstract
The paper presents the results of a comparative epidemiological study of thermal injury and fatal hypothermia based on the results of consolidated reports of the Bureau of Forensic Medicine of the Moscow Department of Health for 2017-2019. It was analyzed the archival material for three calendar years. It was used a continuous retrospective research method with an assessment of the general aggregate of the death incidence from thermal injury and hypothermia in Moscow in 2017-2019 by means of nonparametric statistical methods. Deaths from thermal injury and hypothermia are the most often accidents. The incidence of this type of death is characterized by ups and downs depending on the season. May, January and December are the most dangerous for burns. A similar pattern, with the exception of May, was noted for hypothermia. It was found that men aged 50-70 and women of 70-90 years old die most often. It was determined that most social characteristics (education, being married, etc.) alter the average age when deaths occur. The results obtained provide statistical justification for further more thorough study of thermal injury and hypothermia.

Abstract
For critically ill burn patients without a next of kin, the medical team is tasked with becoming the surrogate decision maker. This poses ethical and legal challenges for burn providers. Despite this frequent problem, there has been no investigation of how the presence of a next of kin affects treatment in burn patients. To evaluate this relationship, a retrospective chart review was performed on a cohort of patients who died during the acute phase of their burn care. Variables collected included age, gender, length of stay, total body surface area, course of treatment, and presence of a next of kin. In total, 67 patients met the inclusion criteria. Of these patients, 14 (21%) did not have a next of kin involved in medical decisions. Patients without a next of kin were significantly younger (P = .02), more likely to be homeless (P < .01), had higher total body surface area burns (P = .008), had shorter length of stay (P < .001), and were five times less likely to receive comfort care (P = .01). Differences in gender and ethnicity were not statistically significant. We report that patients without a next of kin present to participate in medical decisions are transitioned to comfort care less often despite having a higher burden of injury. This disparity in standard of care demonstrates a need for a cultural shift in burn care to prevent the suffering of these marginalized patients. Burn providers should be empowered to reduce suffering when no decision maker is present.

[PMID: 33342706 DOI: 10.1016/j.jfma.2020.12.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 10/14/2020] [Accepted: 12/03/2020] [Indexed: 10/22/2022] Open
Abstract
BACKGROUND Infections are the most common complications among hospitalized severe burn patients. However, limited literature reports early effective predictors of bloodstream infections (BSI) among burn patients. This study aimed to identify cost-effective biomarkers and valuable clinical scoring systems in the emergency department (ED) for the prediction of subsequent BSI in mass burn casualties. METHODS In 2015, a flammable cornstarch-based powder explosion resulted in 499 burn casualties in Taiwan. A total of 35 patients were admitted at Taipei Veterans General Hospital. These severe burn patients (median total body surface area [TBSA] 54%) were young and previously healthy. We assessed the potential of various parameters to predict subsequent BSI, including initial laboratory tests performed at the ED, TBSA, and multiple scoring systems. RESULTS Fourteen patients (40.0%) had subsequent BSI. The most common causative pathogen was the Acinetobacter baumannii (Ab) group, mostly carbapenem resistant and associated with a poor outcome. The area under the receiver operating characteristic curve revealed that the revised Baux score, TBSA, and initial white blood cell count had excellent discrimination ability in predicting subsequent BSI (0.898, 0.889, and 0.821, respectively). The rate of subsequent BSI differed significantly at the cut-off points of revised Baux score >76, TBSA >55%, and WBC count >16,200/mm3. CONCLUSION The initial WBC count at the ED, TBSA, and revised Baux score were good and cost-effective biomarkers for predicting subsequent BSI after burn injuries.

Abstract
Background and Purpose : Despite advances in burn care and management, infections are still a major contributor to morbidity and mortality rates in patients with burn injuries. Regarding this, the present study was conducted to investigate the prevalence and importance of candidemia in pediatric burn patients. Materials and Methods: Blood samples were collected from the patients and cultured in an automated blood culture system. Candida species were identified using specific culture media. The relationship between candidemia and possible risk factors was evaluated and compared to a control group. Results: A total of 71 patients with the mean age of 4.52±3.63 years were included in the study. Blood cultures showed candidemia in 19 (27%) patients. Based on the results,
C. albicans was the most common fungus among patients with and without candidemia. The results of statistical analysis also showed that
candidemia was significantly correlated with total body surface area (TBSA), mechanical ventilation, duration of total parenteral
nutrition, length of intensive care unit (ICU) stay, presence of neutropenia, and R-Baux score (all P≤0.001). In this regard, TBSA, length of ICU stay, R-Baux score, and Candida score were identified as the determinant factors for mortality due to candidemia. Conclusion: Candidemia increases the mortality and morbidity rates associated with burn injuries. Prompt diagnostic and prevention measures can reduce the unfortunate outcomes via controlling the possible risk factors.

Abstract
Background In modern-day burn care, advanced age remains an important predictor for mortality among burn victims. In this study, we compared the complete treatment trajectory (including pre-hospital and surgical treatment) and the outcomes between an elderly burn population and a younger adult burn population. Methods In this nationwide study, data from the Dutch Burn Repository were used. This is a uniform national registration for Dutch specialized burn care. All adult patients that were admitted to one of the three Dutch burn centres from the period 2009 to 2015 were included in the analysis. Burn patients were considered as elderly when ≥65 years of age, and were then further subdivided into three age categories: 65-74, 75-85 and 85+ years. Younger adults in the age category 18-64 years were used as the reference group.Surgical management was studied comprehensively and included timing of surgery, the number of procedures and details on the surgical technique, especially the technique used for debridement and the grafting technique that was applied.For the comparison of clinical outcome, the following parameters were included: mortality, wound infections, length of stay/TBSA (total body surface area) burned, discharge disposition and secondary reconstructions. Results During the study period, 3155 adult patients were included (elderly, n = 505). Burn severity, reflected by the median TBSA, varied between 3.2-4.0% and was comparable, but aetiology and pre-hospital care were different between elderly and the younger adult reference group.Surgical treatment was initiated significantly faster in elderly burn patients (p < 0.001). Less selective techniques for surgical debridement were used in the elderly burns patients (hydrosurgery, 42.0% vs 23.5-22.6%), and on the other hand more avulsion (5.3% vs 7.3-17.6%) and primary wound closure (6.7% vs 24.5%). The most frequently used grafting technique was meshed skin grafts (79.2-88.6%); this was not related to age.Mortality increased rapidly with a higher age and showed a high peak in the 85+ category (23.8%). Furthermore, considerable differences were found in hospital discharge disposition between the elderly and the reference group. Conclusions In conclusion, elderly burn patients who require specialized burn care are vulnerable and medically challenging. Differences in aetiology, comorbidity, physiology and the management prior to admission possibly affect the initial surgical management and result in significantly worse outcomes in elderly. Elderly patients need optimal, timely and specialized burn care to enhance survival after burn injuries.

Abstract
Amputation following burn injury is rare. Previous studies describe the risk of amputation after electrical burn injuries. Therefore, we describe the distribution of amputations and evaluate risk factors for amputation following burn injury at a large regional burn center. We conducted a retrospective analysis of patients ≥17 years admitted from January 2002 to December 2015. Patients who did and did not undergo an amputation procedure were compared. A multivariate logistic regression model was used to determine the risk factors for amputation. Amputations were further categorized by extremity location and type (major, minor) for comparison. Of the 8313 patients included for analysis, 1.4% had at least one amputation (n = 119). Amputees were older (46.7 ± 17.4 years) than nonamputees (42.6 ± 16.8 years; P = .009). The majority of amputees were white (47.9%) followed by black (39.5%) when compared with nonamputees (white: 57.1%, black: 27.3%; P = .012). The most common burn etiology for amputees was flame (41.2%) followed by electrical (23.5%) and other (21.9%). Black race (odds ratio [OR]: 2.29; 95% confidence interval [CI]: 1.22-4.30; P = .010), electric (OR: 13.54; 95% CI: 6.23-29.45; P < .001) and increased %TBSA (OR: 1.03; 95% CI: 1.02-1.05; P < .001) were associated with amputation. Burn etiology, the presence of preexisting comorbidities, black race, and increased %TBSA increase the odds of post burn injury. The role of race on the risk of amputation requires further study.

Abstract
This study examines health outcomes in burn patients with sepsis. We hypothesized that burn patients with sepsis would have an increased odds risk for in-hospital death and longer intensive care unit (ICU) stays. This was a retrospective cohort of consecutive patients admitted to the burn ICU with total BSA (TBSA) ≥10% and/or inhalation injury between January 2008 and March 2015. Overall 407 burn patients were included; the case-rate for sepsis was 39.1% (n = 159); 20.1% (n = 82) patients were septic and 18.9% (n = 77) patients experienced septic shock. Patients with septic shock had the highest mortality rate (13.31% no sepsis vs 3.7% sepsis vs 49.4% septic shock, P < .01). Median 28-day ICU-free days was higher in patients without sepsis (23 days [Interquartile range (IQR) 14-27] no sepsis vs 0 days [IQR 0-10] sepsis vs 0 days [IQR 0-0] septic shock, P < .01). Sepsis (with or without shock) increased odds of in-hospital death (odds ratio 7.04, 95% confidence interval 1.93-25.7) in reference to the no sepsis group. With each incremental Sequential Organ Failure Assessment (SOFA) score or 10% TBSA increase, the odds risk for in-hospital death increased by 56 and 75%, respectively. Our study characterized outcomes in patients with sepsis after severe burn injury. The odds risk for in-hospital death was greater in patients with sepsis, increasing burn severity according to TBSA and SOFA score.

Abstract
Preburn comorbidities increase the risk of death in the acute phase, and negatively impact quality of life among survivors. Investigations to date have only evaluated comorbidities as indices, limiting the ability to target conditions and develop strategies for risk reduction. Therefore, we aimed to evaluate the differential effects of specific conditions on long-term, patient-reported outcomes after burn injury. A prospectively maintained trauma registry was merged with a longitudinal database of patient-reported outcomes from a regional burn center from 2007 to 2018. Demographic data, injury-specific information, and the prevalence of 20 comorbidities were systematically documented. The impact of comorbidities on responses to Short Form-12/Veterans RAND 12 (SF/VR-12) health surveys at 6, 12, and 24 months postinjury was evaluated with generalized linear models. The merged dataset included 493 adult participants. Median age was 46 years (interquartile range, IQR 32-57 years), and 72% were male. Median burn size was 14% TBSA (IQR 5-28%). Seventy percent of participants had ≥1 comorbidity (median 1 comorbidity/participant; IQR 0-2 comorbidities). SF/VR-12 mental component summary scores at 6 and 12 months postinjury were negatively associated with mental illness (P < .001, P = .013). SF/VR-12 physical component summary (PCS) scores were negatively associated with smoking (P = .019), diabetes (P = .001), and alcohol use disorder (P = .001) at 6-month follow-up. Twelve-month SF/VR-12 PCS scores were negatively associated with prior trauma admission (P = .001) and diabetes (P = .042). Twenty-four-month SF/VR-12 PCS scores were negatively associated with mental illness (P = .003). Smoking, alcohol use disorder, and diabetes were associated with lower PCS scores 6 months after injury; diabetes persisted as a negatively associated covariate at 12 months. Mental component summary scores were negatively associated with mental illness 6 and 12 months postinjury. Integrated models of postdischarge comorbidity management need to be tested in burn patients.

Abstract
BACKGROUND Severe burn injuries are associated with high morbidity and mortality. Well-implemented scoring systems for patients with major burns exist in the literature. A major disadvantage of these scores is the partial non-consideration of patient-related comorbidities. Published data on this matter is limited to small study cohorts and/or single center studies. Further, the effect of comorbidities on clinical outcome of patients with severe burn injuries has not yet been examined nationwide in a large cohort in Germany. Hence, the aim of this study was to examine the influence of comorbidities on clinical outcome of these patients based on data from the national registry. METHODS Anonymized data from a total of 3455 patients with documented burns of 1% or more Total Burn Surface Area (TBSA) and over 16 years of age included in the German Burn Registry between 2017 and 2018 were analyzed retrospectively. Data included burn extent, body weight, age, burn depth, inhalation injury, comorbidities, mortality, number of operations and length of hospital stay (LOS). RESULTS In the logistic regression analysis age (OR 1.07 [1.06-1.09], p < 0.001), TBSA (OR 1.09 [1.08-1.11], p < 0.001), IHT (OR 2.15 [1.44-3.20], p < 0001), third degree burn (OR 2.08 [1.39-3.11], p < 0.001), Chronic Obstructive Pulmonary Disease (COPD) (OR 2.45 [1.38-4.35], p = 0.002) and renal insufficiency (OR 2.02 [1.13-3.59], p = 0.017) influenced mortality significantly. If a patient had more than one comorbidity, mortality was higher and in-hospital length of stay (LOS) longer. Renal insufficiency was significantly (p < 0.001) associated with the most prolonged LOS by 11.44 days. TBSA (p < 0.001), Abbreviated Burn Severity Index (ABSI) > 3 (p < 0.001) and IHT (p = 0.001) correlated with the amount of required surgeries and significantly predicted the need for intubation. Patients with arrhythmia significantly required more surgeries (p = 0.041), whereas patients with COPD required significantly less surgical interventions (p = 0.013). CONCLUSION Preexisting comorbidities have a significant impact on the clinical outcome of patients with severe burn injuries. Further investigation is warranted in order to supplement existing prognostic scores with new mortality-associated parameters.

Abstract
OBJECTIVE To derive and validate a prediction model for the development of ARDS in burn-injured patients. SUMMARY BACKGROUND DATA Burn injury carries the highest incidence of acute respiratory distress syndrome (ARDS) among all predisposing conditions, but few studies exist on risk factors in these patients. Studies employing biomarkers and clinical risk factors for predicting ARDS mortality have recently been examined but none exist for onset of ARDS nor in patients with burn injury. METHODS This was a prospective multicenter study of 113 patients with isolated burn injury or inhalation injury. Clinical variables and plasma biomarkers representative of endothelial injury, epithelial injury, or inflammation were collected within 24 hours of admission. The most parsimonious model was chosen by considering discrimination, calibration, and model fit. RESULTS Among the biomarkers measured in patients with burn injuries, a one-standard deviation increase in log-transformed levels of the A2 domain of von Willebrand factor in the first 24 hours was most strongly associated with the development of ARDS (OR 7.72; 95% CI: 1.64-36.28, P = 0.03). Of candidate models, a 3-variable model with %TBSA, inhalation injury, and von Willebrand factor-A2 had comparable discrimination to more complex models (area under the curve: 0.90; 95% CI 0.85-0.96). The 3-variable model had good model fit by Hosmer-Lemeshow test (P = 0.74) and maintained similar discrimination after accounting for performance optimism (Bootstrapped area under the curve: 0.90; 95% CI: 0.84-0.95). CONCLUSIONS The 3-variable model with %TBSA, inhalation injury, and von Willebrand factor could be used to better identify at-risk patients for both the study and prevention of ARDS in patients with burn injury.

Abstract
BACKGROUND Adequate fluid titration during the initial resuscitation period of major burn patients is crucial. This study aimed to evaluate the feasibility and efficacy of a goal-directed fluid resuscitation protocol that used hourly urine output plus the arterial waveform analysis FloTrac (Edwards LifeSciences, Irvine, Calif) system for major burns to avoid fluid overload. METHODS We conducted a retrospective cohort study of 43 major burn patients at the Tri-Service General Hospital after the Formosa Fun Coast Dust Explosion on June 27, 2015. Because of the limited capacity of intensive care units (ICUs), 23 intubated patients were transferred from the burn wards or emergency department to the ICU within 24 hours. Fluid administration was adjusted to achieve a urine output of 30 to 50 mL/h, cardiac index greater than 2.5 L/min/m, and stroke volume variation (SVV) less than 12%. The hourly crystalloid fluid infusion rate was titrated based on SVV and hourly urine output. RESULTS Of the 23 critically burned patients admitted to the ICU, 13 patients who followed the goal-directed fluid resuscitation protocol within 12 hours postburn were included in the analysis. The mean age (years) was 21.8, and the mean total body surface area (TBSA) burned (%) was 68.0. The mean Revised Baux score was 106.8. All patients sustained inhalation injury. The fluid volumes administered to patients in the first 24 hours and the second 24 hours (mL/kg/% total body surface area) were 3.62 ± 1.23 and 2.89 ± 0.79, respectively. The urine outputs in the first 24 hours and the second 24 hours (mL/kg/h) were 1.13 ± 0.66 and 1.53 ± 0.87, respectively. All patients achieved the established goals within 32 hours postburn. In-hospital mortality rate was 0%. CONCLUSIONS The SVV-based goal-directed fluid resuscitation protocol leads to less unnecessary fluid administration during the early resuscitation phase. Clinicians can efficaciously manage the dynamic body fluid changes in major burn patients under the guidance of the protocol.

Abstract
Background Psychiatric and substance use disorders are common among trauma and burn patients and are known risk factors for repeat episodes of trauma, known as trauma recidivism. The epidemiology of burn recidivism, specifically, has not been described. This study aimed to characterize cases of burn recidivism at a large US tertiary care burn center and compare burn recidivists (RCs) with non-recidivists (NRCs). Methods A 10-year retrospective descriptive cohort study of adult burn patients admitted to the North Carolina Jaycee Burn Center was conducted using data from an electronic burn registry and the medical record. Continuous variables were reported using medians and interquartile ranges (IQR). Chi-square and Wilcoxon-Mann-Whitney tests were used to compare demographic, burn, and hospitalization characteristics between NRCs and RCs. Results A total of 7134 burn patients were admitted, among which 51 (0.7%) were RCs and accounted for 129 (1.8%) admissions. Of the 51 RCs, 37 had two burn injuries each, totaling 74 admissions as a group, while the remaining 14 RCs had between three and eight burn injuries each, totaling 55 admissions as a group. Compared to NRCs, RCs were younger (median age 36 years vs. 42 years, p = 0.02) and more likely to be white (75% vs. 60%, p = 0.03), uninsured (45% vs. 30%, p = 0.02), have chemical burns (16% vs. 5%, p < 0.0001), and have burns that were ≤ 10% total body surface area (89% vs. 76%, p = 0.001). The mortality rate for RCs vs. NRCs did not differ (0% vs. 1.2%, p = 0.41). Psychiatric and substance use disorders were approximately five times greater among RCs compared to NRCs (75% vs. 15%, p < 0.001). Median total hospital charges per patient were nearly three times higher for RCs vs. NRCs ($85,736 vs. $32,023, p < 0.0001). Conclusions Distinct from trauma recidivism, burn recidivism is not associated with more severe injury or increased mortality. Similar to trauma recidivists, but to a greater extent, burn RCs have high rates of comorbid psychiatric and medical conditions that contribute to increased health care utilization and costs. Studies involving larger samples from multiple centers can further clarify whether these findings are generalizable to national burn and trauma populations.

Abstract
Objective To investigate the association between serum phosphate levels and the risk of
28-day mortality in critically-ill patients with septic acute kidney injury
(AKI) undergoing continuous renal replacement therapy (CRRT). Methods This retrospective cohort study analysed data from critically-ill patients
with septic AKI who underwent CRRT between January 2009 and September 2016.
Demographic, clinical and routine biochemical data were retrieved from a
database and analysed to identify risk factors for 28-day mortality. Results A total of 796 patients were included in the analyses. Multivariate
regression analyses showed that phosphate (0 h), phosphate (24 h) and delta
phosphate were associated with the 28-day mortality in patients with septic
AKI undergoing CRRT. The adjusted odds ratios (95% confidence interval) were
1.12 (1.03, 1.22), 1.22 (1.14, 1.30) and 1.12 (1.04, 1.20) for phosphate
(0 h), phosphate (24 h) and delta phosphate, respectively. Curve fitting and
threshold analyses showed that when phosphate (0 h) was between 5.6 mg/dl
and 8.7 mg/dl, phosphate (24 h) was >3.8 mg/dl and delta phosphate was
>–1, the 28-day mortality risk increased significantly. Conclusion In patients with septic AKI undergoing CRRT, serum phosphate level was
associated with the prognosis of patients in terms of 28-day mortality.

Abstract
RESUMO Objetivo: avaliar a eficácia da estratégia adotada e a qualidade do atendimento em trauma pediátrico na sobrevivência dos pacientes atendidos após desastre em uma cidade do interior de Minas Gerais, em comparação a resultados esperados por estudos sobre mortalidade infantil em grandes queimados. Métodos: análise retrospectiva observacional de dez pacientes que sofreram queimaduras e foram transferidos para um centro de referência de trauma. Utilizou-se o escore de R-Baux modificado para estimar a mortalidade esperada. Comparou-se a mortalidade esperada a partir do escore de R-Baux e a mortalidade real, a partir do teste de uma proporção. Comparou-se, também, tempo de admissão pós-trauma com mortalidade e grau de superfície corporal queimada com mortalidade. Resultados: o R-Baux médio foi de 75,2, o que significa uma mortalidade esperada para grandes queimados de 5%. No entanto, a mortalidade do grupo com grande área de superfície corporal queimada desse estudo foi de 60%, valor p=0,001. Observou-se neste caso uma mortalidade muito além da esperada pela literatura. Conclusão: apesar das inúmeras variáveis, aventa-se a hipótese de infraestrutura de atendimento em trauma pediátrico aquém da necessária no Estado. Este estudo sugere maior incentivo à políticas públicas para atendimento de trauma pediátrico, centro de referência preparado, acordos de transferência bem estabelecidos e otimização de planos de catástrofe para diminuição da morbimortalidade para os pacientes que sobrevivem à primeira hora após o trauma.

Abstract
BACKGROUND Acute kidney injury (AKI) is a common complication in severe burns and can lead to significantly poorer outcomes. Although the prognosis has improved in recent decades, the mortality of AKI remains considerable. We investigated the factors that increase the risk of AKI and death after severe burn injury. METHODS Intensive care patients with ≥20% burned total body surface area (TBSA%) between January 2006 and December 2015 treated in Helsinki Burn Centre were enrolled retrospectively. Patients who arrived > 36 h after burn injury or died < 48 h from arrival were excluded. A total of 187 patients were included in the final analysis. Serum creatinine ≥120 μmol/l (1.4 mg/dl) was the criterion for AKI. RESULTS Fifty-one patients (27.3%) developed AKI during hospital stay and 21 (11.2%) required renal replacement therapy (RRT); 37 patients (19.8%) died during hospital stay. Mortality was significantly higher in the AKI group (52.9%) than in the AKI-negative group (7.4%). The Abbreviated Burn Severity Index (ABSI), Baux, and the modified Baux score were nearly equivalent in predicting mortality during ICU stay (AUC: 0.83-0.84). The risk of death and AKI were minimal with Baux scores < 80. LD50 was 112 for Baux score in all patients. In flame burns, the risk of death increased rapidly after Baux score > 80. Multivariate logistic regression model detected age, TBSA%, sepsis, and rhabdomyolysis as independent risk factors for AKI. Age (per 10 yrs. OR 1.99), TBSA% (per 10% OR 1.64), and AKI predicted mortality during hospital stay; AKI had an odds ratio of (OR) of 5.97 (95% confidence interval [CI] 2.2-16.2). CONCLUSIONS Age, TBSA%, and AKI were the strongest independent factors in predicting outcome in severe burns. Even a major burn (> 50% TBSA) has a relatively good prognosis without simultaneous AKI. Prognosis is poorer even in minor burns for patients with AKI.

Abstract
INTRODUCTION Discussions regarding withdrawal of life support after burn injury are challenging and complex. Often, providers may facilitate this discussion when the extent of injury makes survival highly unlikely or when the patient's condition deteriorates during resuscitation. Few papers have evaluated withdrawal of life support in burn patients. We therefore sought to determine the predictor of withdrawal of life support (WLS) in a regional burn center. METHODS We conducted a retrospective analysis of all burn patients from 2002 to 2012. Patient characteristics included age, gender, burn mechanism, percentage total body surface area (%TBSA) burned, presence of inhalation injury, hospital length of stay, and pre-existing comorbidities. Patients <17years of age and patients with unknown disposition were excluded. Patients were categorized into three cohorts: Alive till discharge (Alive), death by withdrawal of life support (WLS), or death despite ongoing life support (DLS). DLS patients were then excluded from the study population. Multivariate logistic regression was used to estimate predictors of WLS. RESULTS 8,371 patients were included for analysis: 8134 Alive, 237 WLS. Females had an increased odd of WLS compared to males (OR 2.03, 95% CI 1.18-3.48; p=0.010). Based on higher CCI, patients with pre-existing comorbidities had an increased odd of WLS (OR 1.28, 95% CI 1.08-1.52; p=0.005). There was a significantly increased odds for WLS (OR 1.09, 95% CI 1.06-1.12; p<0.001) with increasing age. Similarly, there was an increased odd for WLS (OR 1.08, 95% CI 1.07-1.51; p<0.001) with increasing %TBSA. An increased odd of WLS (OR 2.47, 95% CI 1.05-5.78; p=0.038) was also found in patients with inhalation injury. CONCLUSION The decision to withdraw life support is a complex and difficult decision. Our current understanding of predictors of withdrawal of life support suggests that they mirror those factors which increase a patient's risk of mortality. Further research is needed to fully explore end-of-life decision making in regards to burn patients. The role of patient's sex, particularly women, in WLS decision making needs to be further explored.

Abstract
BACKGROUND/PURPOSE We reported an outbreak of Staphylococcus haemolyticus (SH) infection in a group of young patients (mean age 21.6) simultaneously hospitalized due to a mass-burn incident. This study analyzed the clinical features of these patients and the microbiological characteristics of the outbreak. METHODS All 50 patients hospitalized for burns were enrolled, and their clinical differences were analyzed based on culture results. A drug sensitivity test and pulsed-field gel electrophoresis (PFGE) were conducted to analyze the microbiological difference between SH isolates from the mass-burn casualty patients (the study group) and SH isolates from other patients hospitalized during the same period (the control group) with the intention of identifying the strain of SH outbreak. RESULTS Patients with isolated SH (N = 36) had a significantly higher disease severity (higher revised Baux score, APACHE II score, and concurrent bacteremia rate), and a significantly poorer clinical outcome (longer ICU and hospital stay, and longer MV usage). Significant differences in the phenotype (antibiotics drug sensitivity test) and genotype (PFGE typing) were observed between the study and control groups. The dominant PFGE type C identified among the study group was related to poorer outcomes in a subgroup analysis. CONCLUSION A dominant PFGE type of SH infection was found in these mass-burn casualty patients. Pathogenesis or virulence factors may have contributed to our results. Further study of isolated SH should be conducted.

Abstract
In the UK, a network of specialist centres has been set up to provide critical care for burn patients. However, some burn patients are admitted to general intensive care units. Little is known about the casemix of these patients and how it compares with patients in specialist burn centres. It is not known whether burn-specific or generic risk prediction models perform better when applied to patients managed in intensive care units. We examined admissions for burns in the Case Mix Programme Database from April 2010 to March 2016. The casemix, activity and outcome in general and specialist burn intensive care units were compared and the fit of two burn-specific risk prediction models (revised Baux and Belgian Outcome in Burn Injury models) and one generic model (Intensive Care National Audit and Research Centre model) were compared. Patients in burn intensive care units had more extensive injuries compared with patients in general intensive care units (median (IQR [range]) burn surface area 16 (7-32 [0-98])% vs. 8 (1-18 [0-100])%, respectively) but in-hospital mortality was similar (22.8% vs. 19.0%, respectively). The discrimination and calibration of the generic Intensive Care National Audit and Research Centre model was superior to the revised Baux and Belgian Outcome in Burn Injury burn-specific models for patients managed on both specialist burn and general intensive care units.

Abstract
Classic determinants of burn mortality are age, burn size, and the presence of inhalation injury. Our objective was to describe temporal trends in patient and burn characteristics, inpatient mortality, and the relationship between these characteristics and inpatient mortality over time. All patients aged 18 years or older and admitted with burn injury, including inhalation injury only, between 2004 and 2013 were included. Adjusted Cox proportional hazards regression models were used to estimate the relationship between admit year and inpatient mortality. A total of 5540 patients were admitted between 2004 and 2013. Significant differences in sex, race/ethnicity, burn mechanisms, TBSA, inhalation injury, and inpatient mortality were observed across calendar years. Patients admitted between 2011 and 2013 were more likely to be women, non-Hispanic Caucasian, with smaller burn size, and less likely to have an inhalation injury, in comparison with patients admitted from 2004 to 2010. After controlling for patient demographics, burn mechanisms, and differential lengths of stay, no calendar year trends in inpatient mortality were detected. However, a significant decrease in inpatient mortality was observed among patients with extensive burns (≥75% TBSA) in more recent calendar years. This large, tertiary care referral burn center has maintained low inpatient mortality rates among burn patients over the past 10 years. While observed decreases in mortality during this time are largely due to changes in patient and burn characteristics, survival among patients with extensive burns has improved.

Abstract
Thrombocytopenia is a common event in severely burned patients and associated with adverse outcome. The underlying relationship between the dynamic changes of platelet counts and mortality has not been well defined. We performed a 6-year retrospective chart of adult patients with a burn index of 50 or greater admitted to two burn centers and collected data on patient demographics, laboratory results, and patient outcomes. The mean daily increase in the platelet count (∆PC/∆t) from day 3 to day 10 was calculated, and 30-day mortality was determined. For the study, 141 survivors and 65 nonsurvivors were enrolled. The sequential changes in PCs presented a biphasic pattern after admission, with a slump to the nadir during the first 3 days and a subsequent recovery. With respect to 30-day mortality, compared with the AUC of APACHE-Ⅱ score (0.841), no significant difference was noted between ΔPC/ΔT and APACHE-Ⅱ score (p = 0.0648). The ΔPC/ΔT associated with the best discrimination between survivors and nonsurvivors was 20.57 × 109/L due to the cutoff with optimal Youden index (0.453). By multiple logistic regression, ΔPC/ΔT < 20.57 × 109/L was one of the prognostic predictors of 30-day mortality. Furthermore, Kaplan-Meier estimates of hospital survival according to the size of ΔPC/ΔT revealed that a blunted increase with ΔPC/ΔT < 20.57 × 109/L was associated with increased 30-day mortality. A blunted daily increase in PCs, especially ΔPC/ΔT < 20.57 × 109/L, is associated with increased 30-day mortality, which provides prognostic information for mortality risk assessment in severely burned patients.

Abstract
Burn injuries are a pervasive clinical problem. Extensive thermal trauma can be life-threatening or result in long-lasting complications, generating a significant impact on quality of life for patients as well as a cost burden to the healthcare system. The importance of addressing global or systemic issues such as resuscitation and management of inhalation injuries is not disputed but is beyond the scope of this review, which focuses on cutaneous pathophysiologic mechanisms for current treatments, both in the acute and long-term settings. Pathophysiological mechanisms of burn progression and wound healing are mediated by highly complex cascades of cellular and biochemical events, which become dysregulated in slow-healing wounds such as burns. Burns can result in fibroproliferative scarring, skin contractures, or chronic wounds that take weeks or months to heal. Burn injuries are highly individualized owing to wound-specific differences such as burn depth and surface area, in addition to patient-specific factors including genetics, immune competency, and age. Other extrinsic complications such as microbial infection can complicate wound healing, resulting in prolonged inflammation and delayed re-epithelialization. Although mortality is decreasing with advancements in burn care, morbidity from postburn deformities continues to be a challenge. Optimizing specialized acute care and late burn outcome intervention on a patient-by-patient basis is critical for successful management of burn wounds and the associated pathological scar outcome. Understanding the fundamentals of integument physiology and the cellular processes involved in wound healing is essential for designing effective treatment strategies for burn wound care as well as development of future therapies.

Procalcitonin as a diagnostic biomarker for septic shock and bloodstream infection in burn patients from the Formosa Fun Coast dust explosion. JOURNAL OF MICROBIOLOGY, IMMUNOLOGY, AND INFECTION = WEI MIAN YU GAN RAN ZA ZHI 2017; 50:872-878. [PMID: 28690030 DOI: 10.1016/j.jmii.2016.08.021] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2016] [Revised: 08/21/2016] [Accepted: 08/26/2016] [Indexed: 01/16/2023]
Abstract
BACKGROUND/PURPOSE Infection is the most common cause of death following burn injury. The study was conducted to compare the diagnostic value of serum procalcitonin (PCT) with the other current benchmarks as early predictors of septic shock and bloodstream infection in burn patients. METHODS We included 24 patients admitted to the Burn Unit of a medical center from June 2015 to December 2015 from the Formosa Fun Coast dust explosion. We categorized all patients at initial admission into either sepsis or septic shock groups. Laboratory tests including the worst PCT and C-reactive protein (CRP) levels, platelet (PLT), and white blood cell (WBC) count were performed at <48 h after admission. Patients were also classified in two groups with subsequent bacteremia and non-bacteremia groups during hospitalization. RESULTS Significantly higher PCT levels were observed among participants with septic shock compared to those with sepsis (47.19 vs. 1.18 ng/mL, respectively; p < 0.001). Patients with bacteremia had significantly elevated PCT levels compared to patients without bacteremia (29.54 versus 1.81 ng/mL, respectively, p < 0.05). No significant differences were found in CRP levels, PLT, and WBC count between the two groups. PCT levels showed reasonable discriminative power (cut-off: 5.12 ng/mL; p = 0.01) in predicting of bloodstream infection in burn patients and the area under receiver operating curves was 0.92. CONCLUSIONS PCT levels can be helpful in determining the septic shock and bloodstream infection in burn patients but CRP levels, PLT, and WBC count were of little diagnostic value.

Abstract
Failed burn resuscitation can occur at various points. Early failed resuscitation will be largely caused by prehospital factors. During resuscitation, failure will present as a patient's nonresponse to adjunctive therapy. Late failure will occur in the setting of multiple organ dysfunction syndrome. Burn care providers must be vigilant during the resuscitation to identify a threatened resuscitation so that adjunctive therapies or rescue maneuvers can be used to convert to a successful resuscitation. However, when a patient's resuscitative course becomes unsalvageable, transition to comfort care should be taken to avoid prolongation of suffering.
