Metabolic and Nutritional Support.

Hypermetabolism is a hallmark of larger burn injuries. The hypermetabolic response is characterized by marked and sustained increases in catecholamines, glucocorticoids, and glucagon. There is an increasing body of literature for nutrition and metabolic treatment and supplementation to counter the hypermetabolic and catabolic response secondary to burn injury. Early and adequate nutrition is key in addition to adjunctive therapies, such as oxandrolone, insulin, metformin, and propranolol. The duration of administration of anabolic agents should be at minimum for the duration of hospitalization, and possibly up to 2 to 3 years postburn.

Novel Design and Implementation of an Integrated Burn Rehabilitation Clinical Fellowship.

ABSTRACT: Postgraduate medical burn rehabilitation training has been limited, with very few academic physiatrists specializing in burn rehabilitation. As a result, there are no existing models for postgraduate burn rehabilitation education. A 12-mo comprehensive clinical fellowship in burn rehabilitation was offered through a tertiary burn center with formal university accreditation. In this article, the clinical, educational, and skill-based goals developed and implemented for this novel fellowship was outlined to serve as a blueprint for future fellowships in burn rehabilitation, as well as reflections on the experience.

Time to surgical closure of complex infectious wounds: a single-center retrospective cohort study.

INTRODUCTION: Surgical management of NSTIs can result in complex wounds, and closure of these wounds is often difficult or complicated. Although surgical factors influencing mortality and LOS have been well described, little is known about patient, wound, and surgical factors associated with time to closure. OBJECTIVE: The purpose of this study is to identify patient, wound, and surgical factors that may influence time to closure of NSTIs. MATERIALS AND METHODS: The records of patients who presented to a tertiary care center over an 11-year period (2007-2017) with an NSTI requiring surgical closure were retrospectively reviewed. RESULTS: Forty-seven patients met the inclusion criteria. The average time to closure was 31.1 days, with an average of 4.8 procedures. Most patients were middle aged (mean, 50.3 years; range, 20-81 years), immunocompetent, and nondiabetic upon admission. Closure was achieved mainly with autograft. The percent TBSA was described in 19 cases (40%). There was no association between substance use (alcohol, smoking, or other), anticoagulant medication use, or medical comorbidities and time to closure. On multivariable analysis, flap closure (P =.02) and increased number of surgical procedures (P =.003)-the latter reflecting the need for an increased number of debridements-were associated with increased time to closure. CONCLUSIONS: The data in this study suggest that use of local flaps for wound closure and increased number of surgical procedures (particularly debridements) may be predictors of time to closure in patients with an NSTI.

Use of a fluorescence imaging device to detect elevated bacterial loads, enhance antimicrobial stewardship, and increase communication across inpatient complex wound care teams.

INTRODUCTION: Wounds are increasing in number and complexity within the hospital inpatient system, and coordinated and dedicated wound care along with the use of emerging technologies can result in improved patient outcomes. OBJECTIVE: This prospective implementation study at 2 hospital inpatient sites examines the effect of bedside fluorescence imaging of wounds in the detection of elevated bacterial loads and its location in/around the wound on the inpatient wound population. MATERIALS AND METHODS: Clinical assessment and fluorescence imaging assessments were performed on 26 wounds in 21 patients. Treatment plans were recorded after the clinical assessment and again after fluorescence imaging, and any alterations made to the treatment plans after imaging were noted. RESULTS: Prior to fluorescence imaging, antimicrobial use in this patient population was common. An antimicrobial dressing, a topical antibiotic, or an oral antibiotic was prescribed in 23 wounds (88% of assessments), with antimicrobial dressings prescribed 73% of the time. Based on clinical assessment, more than half of the treated wounds were deemed negative for suspected infection. In 12 of 26 wounds, the fluorescence imaging information on bacterial presence had the potential to prompt a change in whether an antimicrobial dressing was prescribed. Five of these 12 wounds were fluorescence imaging-positive and an antimicrobial drug was not prescribed, whereas 7 of the 12 wounds were negative upon fluorescence imaging and clinical assessment but antimicrobial dressing was prescribed. Overall, fluorescence imaging detected 70% more wounds, with bacterial fluorescence indicating elevated bacterial loads, compared with clinical assessment alone, and use of imaging resulted in altered treatment plans in 35% of cases. CONCLUSIONS: Fluorescence imaging can aid in antimicrobial stewardship goals by supporting evidence-based decision-making at the point of care. In addition, use of such imaging resulted in increased communication, enhanced efficiency, and improved continuity of care between wound care providers and hospital sites.

Outbreak of Carbapenemase-Producing Enterobacteriaceae in a Regional Burn Center.

Antimicrobial resistance is an increasing problem in hospitals worldwide; however, the prevalence of carbapenemase-producing Enterobacteriaceae (CPE) in our region is low. Burn patients are vulnerable to infection because of the loss of the protective skin barrier, thus burn centers prioritize infection prevention and control (IP&C). This report describes a CPE outbreak in a regional burn center. In a period of 2.5 months, four nosocomial cases of CPE were identified, three containing the Klebsiella pneumoniae carbapenemase (KPC) gene and one Verona integrin-encoded metallo-ß-lactamase (VIM) gene. The first two cases were identified while there was no CPE patient source on the unit. CPE KPC gene was then isolated in sink drains of three rooms. In addition to rigorous IP&C practices already in place, we implemented additional outbreak measures including restricting admissions to patients with complex burns or burns ≥10% TBSA, admitting patients to other in-patient units, and not permitting elective admissions. We began cohorting patients using nursing team separation for CPE-positive and -negative patients and geographical separation on the unit. Despite aggressive IP&C measures already in place, hospital-acquired CPE colonization/infection occurred. Given that CPE contaminated sinks of the same enzyme were identified, we believe hospital sink drains may the source. This highlights the importance of sink design and engineering solutions to prevent the formation of biofilm and reduce splashing. CPE infections are associated with poor outcomes in patients and significant health system costs due to a longer length of stay and additional institutional resources.

Comparison of Clinical Outcomes of Lower Extremity Burns in Diabetic and Nondiabetic Patients: A Retrospective Analysis.

Diabetes mellitus is an increasingly prevalent chronic disease that leads to long-term health consequences. Some long-term clinical sequelae of diabetes include coronary artery disease, peripheral vascular disease, peripheral neuropathy, and impaired wound healing. These can increase hospital stay and complications such as wound infections and amputations among patients with lower extremity burns. A retrospective analysis was performed of all isolated lower extremity burns from a single tertiary burn care center from 2006 to 2017. Patients were stratified by diabetic status and the incidence of lower extremity amputations was the primary outcome. Multivariable regression was used to model the association between diabetes and amputations, adjusting for patient and injury characteristics. A total of 198 patients were identified as meeting inclusion criteria, 160 were nondiabetic and 38 were diabetic. Age was significantly different between nondiabetic and diabetic patients; mean age was 46 ± 18 vs 62 ± 17 years (P < .0001). Length of stay was also significantly different, median length of stay was 11 (interquartile range 7-15) vs 18 (interquartile range 12-24; P < .001), with diabetic patients staying longer. There was a significantly greater proportion of diabetic patients that had an amputation (control 4% vs diabetic 29%; P < .0001). After adjustment for patient and injury characteristics, there was a significant association between diabetes and amputation (P = .002). Among patients with isolated lower extremity burns, those with a preexisting condition of diabetes had a longer hospitalization and increased amputations, despite similar size of burn. Diabetes is an important risk factor to acknowledge in patients with these injuries to optimize care.

Identifying Risk Factors That Increase Analgesic Requirements at Discharge Among Patients With Burn Injuries.

Patients with burn injuries require large doses of opioids and gabapentinoids to achieve pain control and are often discharged from hospital with similar amounts. This study aimed to identify patient risk factors that increase analgesic requirements among patients with burn injuries and to determine the relationship between opioid and gabapentinoid use. Patient charts from July 1, 2015 to 2018 were reviewed retrospectively to determine analgesic requirements 24 hours before discharge. Linear mixed regression models were performed to determine patient risk factors (age, gender, history of substance misuse, TBSA of burn, length of stay in hospital, history of psychiatric illness, or surgical treatment) that may increase analgesic requirements. This study found that patients with a history of substance misuse (P = .01) or who were managed surgically (P = .01) required higher doses of opioids at discharge. Similarly, patients who had undergone surgical debridement required more gabapentinoids (P < .001). For every percent increase in TBSA, patients also required 14 mg more gabapentinoids (P = .01). In contrast, older patients (P = .006) and those with a longer hospital stay (P = .009) required fewer amounts of gabapentinoids before discharge. By characterizing factors that increase analgesic requirements at discharge, burn care providers may have a stronger understanding of which patients are at greater risk of developing chronic opioid or gabapentinoid misuse. The quantity and duration of analgesics prescribed at discharge may then be tailored according to these patient specific risk factors.

Burn Infection and Burn Sepsis.

Background: Infection is the most common complication and cause of death in patients suffering burn injuries. These patients are susceptible to infection and burn wound sepsis secondary to the alterations in their physiology. Diagnosis and management of infections rely on physical examination, cultures, and the pathology of the burn wound. Method: We performed an electronic search for articles in the Google Scholar and PubMed databases using the search terms "burn sepsis," "burn infection," and "burn critical care." Results: Multiple factors increase burn patients' risk of invasive infection and sepsis, including underlying factors and co-morbidities, the percent total body surface area of the burn, delays in burn wound excision, and microbial virulence/bacterial count. Organisms causing burn wound infection differ, depending on the time since injury and its location; and diagnosis is multi-factorial. The most common pathogens remain Staphylococcus and Pseudomonas spp. Conclusion: Overall, the recognition of burn sepsis is based on clinical findings. Treatment consists of a combination of local dressings, early burn excision, and systemic antimicrobial therapy. The mortality rate has decreased significantly over the past 10 years, but continued efforts at timely management and infection prevention are essential.

Prescribing patterns of opioids and adjunctive analgesics for patients with burn injuries.

PURPOSE: Large quantities of analgesics are prescribed to control pain among patients with burn injuries and may lead to chronic use and dependency. This study aimed to determine whether patients are overprescribed analgesics at discharge and to identify factors that influence prescribing patterns. MATERIAL AND METHODS: A retrospective review of patient charts (n = 199) between July 1, 2015-2018 were reviewed from a registry at a single burn center. Opioid, neuropathic pain agent, acetaminophen, and ibuprofen quantities given before and at discharge were compared. Linear mixed regression models were used to identify factors that increased the amount of analgesics prescribed. RESULTS: On average, patients were prescribed significantly more analgesics at discharge compared to what was consumed pre-discharge (p < 0.0001). Specifically, on average, providers did not overprescribe the daily dose, but overprescribed the duration of pain medications required. For every increase in percent TBSA, 14 MEQ more opioids, 203 mg more neuropathic pain agents, 843 mg more acetaminophen, and 126 mg more ibuprofen were prescribed (p < 0.05). Surgery was a predictor for higher opioid and neuropathic pain agent prescriptions (p = 0.03), while length of stay was associated with fewer neuropathic pain agents prescribed (p = 0.04). Fewer ibuprofen were given to patients with a history of substance misuse (p = 0.01). CONCLUSIONS: The quantity of analgesics prescribed at discharge varied widely and often prescribed for long durations of time. Standardized prescribing guidelines should be developed to optimize how analgesics are prescribed at discharge.

Anabolic and anticatabolic agents used in burn care: What is known and what is yet to be learned.

Major thermal injury induces profound metabolic derangements secondary to an inflammatory "stress-induced" hormonal environment. Several pharmacological interventions have been tested in an effort to halt the hypermetabolic response to severe burns. Insulin, insulin growth factor 1, insulin growth factor binding protein 3, metformin, human growth hormone, thyroid hormones, testosterone, oxandrolone, and propranolol, among others, have been proposed to have anabolic or anticatabolic effects. The aim of this broad analysis of pharmacological interventions was to raise awareness of treatment options and to help establishing directions for future clinical research efforts. A PubMed search was conducted on the anabolic and anticatabolic agents used in burn care. One hundred and thirty-five human studies published between 1999 and 2017 were included in this review. The pharmacological properties, rationale for the treatments, efficacy considerations and side effect profiles are summarized in the article. Many of the drugs tested for investigational purposes in the severely thermally injured are not yet gold-standard therapies in spite of their potential benefit. Propranolol and oxandrolone have shown great promise but further evidence is still needed to clarify their potential use for anabolic and anticatabolic purposes.

Extremity Mobilization After Split-Thickness Skin Graft Application: A Survey of Current Burn Surgeon Practices.

PURPOSE: To determine the current postoperative mobilization care practice patterns of burn surgeons after split-thickness skin grafting and to assess potential inconsistencies in management strategies. METHODS: A cross-sectional study of active burn surgeons was conducted with an online questionnaire (SurveyMonkey) comprising 7 demographic and 22 mobilization-related questions. RESULTS: Seventy-three (22%) of the 337 members of the American Burn Association mailing list consented to participate in the study, of whom 71 completed the demographic questions and 59 completed the mobilization-related questions. The majority of respondents had more than 10 years of burn care experience (68%) and practiced in an American Burn Association-verified center (70%). Standardized postoperative autograft mobilization protocols were used by 68% of respondents. Most (66%) never or rarely immobilized the upper extremity without joint involvement. When the elbow or wrist was involved, 73% always or very often immobilized. Similarly, 63% never or rarely immobilized the lower extremity without joint involvement. Most immobilized when the knee (70%) or ankle (63%) was involved. Immobilization duration was most commonly 3 or 5 days. Most respondents (71%) reported following Nedelec and colleagues' recommendation that "early postoperative ambulation protocol should be initiated immediately after lower extremity grafting," although there was practice variability. CONCLUSIONS: Our findings reveal that the majority of survey respondents do not immobilize the extremities after autograft without joint involvement. When grafts cross major joints, most surgeons immobilize for 3 or 5 days. Despite some practice variability, surveyed burn surgeons' current lower extremity ambulation practices generally align with the 2012 guidelines of Nedelec et al.

Allogeneic mesenchymal stem cells for treatment of severe burn injury.

The most important determinant of survival post-burn injury is wound healing. For decades, allogeneic mesenchymal stem cells (MSCs) have been suggested as a potential treatment for severe burn injuries. This report describes a patient with a severe burn injury whose wounds did not heal with over 18 months of conventional burn care. When treated with allogeneic MSCs, wound healing accelerated with no adverse treatment complications. Wound sites showed no evidence of keloids or hypertrophic formation during a 6-year follow-up period. This therapeutic use of allogeneic MSCs for large non-healing burn wounds was deemed safe and effective and has great treatment potential.

Management and prevention of drug resistant infections in burn patients.

Introduction: Despite modern advances, the primary cause of death after burns remains infection and sepsis. A key factor in determining outcomes is colonization with multi-drug resistant (MDR) organisms. Infections secondary to MDR organisms are challenging due to lack of adequate antibiotic treatment, subsequently prolonging hospital stay and increasing risk of adverse outcomes. Areas covered: This review highlights the most frequent organisms colonizing burn wounds as well as the most common MDR bacterial infections. Additionally, we discuss different treatment modalities and MDR infection prevention strategies as their appropriate management would minimize morbidity and mortality in this population. We conducted a search for articles on PubMed, Web of Science, Embase, Cochrane, Scopus and UpToDate with applied search strategies including a combination of: "burns, 'thermal injury,' 'infections,' 'sepsis,' 'drug resistance,' and 'antimicrobials.' Expert opinion: Management and prevention of MDR infections in burns is an ongoing challenge. We highlight the importance of preventative over therapeutic strategies, which are easy to implement and cost-effective. Additionally, targeted, limited use of antimicrobials can be beneficial in burn patients. A promising future area of investigation within this field is post-trauma microbiome profiling. Currently, the best treatment strategy for MDR in burn patients is prevention.

Acute Phase Response in Critically Ill Elderly Burn Patients.

OBJECTIVES: Survival of elderly burn patients remains unacceptably poor. The acute phase, defined as the first 96 hours after burn, includes the resuscitation period and influences subsequent outcomes and survival. The aim of this study was to determine if the acute phase response post burn injury is significantly different in elderly patients compared with adult patients and to identify elements contributing to adverse outcomes. DESIGN: Cohort study. SETTING: Tertiary burn center. PATIENTS: Adult (< 65 yr old) and elderly (≥ 65 yr old) patients with an acute burn injury. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We included all patients with an acute burn injury greater than or equal to 20% total body surface area to our burn center from 2011 to 2016. Clinical and laboratory measures during the acute phase were compared between adult and elderly patients. Outcomes included clinical hemodynamic measurements, organ biomarkers, volume of fluid resuscitation, cardiac agents, and the inflammatory cytokine response in plasma. Data were analyzed using the Student t test, Mann-Whitney U test, and Fisher exact test. A total of 149 patients were included, with 126 adults and 23 elderly. Injury severity was not significantly different among adult and elderly patients. Elderly had significantly lower heart rates (p < 0.05), cardiac index (p < 0.05), mean arterial pressure (p < 0.05), PaO2/FIO2 (p < 0.05), and pH (p < 0.05), along with higher lactate (p < 0.05). Organ biomarkers, particularly creatinine and blood urea nitrogen, showed distinct differences between adults and elderly (p < 0.05). Elderly had significantly lower levels of interleukin-6, monocyte chemotactic protein-1, monocyte chemotactic protein-3, and granulocyte-colony stimulating factor during the acute phase (p < 0.05). Overall mortality was significantly higher in elderly patients (5% vs 52%; p < 0.0001). CONCLUSIONS: Response to the burn injury during the acute phase response after burn is substantially different between elderly and adult burn patients and is characterized by cardiac depression and hypoinflammation.

Sepsis criteria versus clinical diagnosis of sepsis in burn patients: A validation of current sepsis scores.

BACKGROUND: Sepsis remains an ongoing diagnostic challenge in burns, especially with the signs of sepsis being ubiquitously present during the acute period after injury. We aimed to determine the predictive validity of 3 current sepsis criteria in the burn population. The criteria of interest included the American Burn Association sepsis criteria, Mann-Salinas et al predictors of sepsis, and the Sepsis-3 consensus definition. METHODS: Adult patients with an acute burn injury who were diagnosed prospectively with sepsis by the burn team using specific clinical markers were included in this cohort study. Sepsis predictors were collected from patient charts and used to calculate the results of the 3 criteria, then subsequently compared to the clinical diagnosis. RESULTS: Of the 418 patients in the study, which took place from 2000 until 2016, 88 (21%) were septic; the mean age was 50 ± 18 years with a mean percent total body surface area burn of 30% ± 17%. Inhalation injury was present in 50%, median length of stay was 49 (29-71) days, and mortality was 19%. The American Burn Association, Mann-Salinas, and Sepsis-3 criteria were positive in 59%, 28%, and 85% respectively, P < .05. The most reliable predictors included increased oxygen requirements, altered mental status, hypothermia, hyperthermia, tachycardia, and hypotension. CONCLUSION: The Sepsis-3 criteria was the most predictive, followed by the American Burn Association and Mann-Salinas criteria. However, no criterion alone had the accuracy to be a diagnostic standard within this burn population. We recommend sepsis is clinically assessed, diagnosed, and documented prospectively by the burn team, and not by the application of retrospective criteria.

The Cost of Burn Transfers: A Retrospective Review of 7 Years of Admissions to a Regional Burn Center.

The transport of thermally injured patients can involve significant costs; however, not all thermally injured patients necessitate transfer to a burn center. The purpose of this study was to review transfers to an American Burn Association-verified regional burn center to determine whether the transfers were necessary and the cost associated with unnecessary transfers. A retrospective chart review identified 707 patients transferred to an American Burn Association-verified burn center with an acute burn injury during a 7-year period. For the purposes of this study, "unnecessary transfer" was defined as any patient admitted fewer than 7 days who did not undergo operative intervention. Transfer cost estimates were based on records from regional land paramedic and land and air medical transport services. In total, 27.3% of transfers were potentially "unnecessary transfers," with an associated cost of approximately $227,396.93 (18.9% of total transfer costs in study). Average unnecessary transfer cost varied by method of transport: land ambulance (n = 130) $285.72, helicopter (n = 27) $4,136.34, and airplane (n = 15) $4,908.67. The transfer of thermally injured patients is associated with significant cost. Unnecessary transfers represent an inefficient use of a limited resource in an already strained healthcare system. The findings of this study suggest that further initiatives should be explored to ensure the appropriate transfer of thermally injured patients.

Antioxidant and Trace Element Supplementation Reduce the Inflammatory Response in Critically Ill Burn Patients.

Oxidative stress after burn injury induces inflammatory and hypermetabolic responses associated with adverse outcomes. We propose that antioxidant and trace element supplementation may reduce oxidative stress and subsequently alleviate inflammation and hypermetabolism, thus improving clinical outcomes. We conducted a cohort study of adult patients with an acute burn injury admitted to our provincial burn center. Patients in the antioxidant group received an intravenous infusion of multivitamins and trace elements for the first 14 days after admission. The inflammatory profile was assessed at early time points, < 14 days postburn, and later time points, ≥ 15 days postburn, and included interleukin (IL)-1ß, interferon-γ, IL-1 receptor antagonist, IL-6, granulocyte-macrophage colony-stimulating factor, and FMS-like tyrosine kinase 3 ligand. Hypermetabolism was assessed by resting energy expenditure. Clinical outcomes included mortality, morbidities, hospital length of stay, and infections including days to the last positive culture after injury. We studied 172 patients, mean age 49 ± 17 years and 33 ± 13% TBSA burned, with 91 controls and 81 patients in the antioxidant group. Patients in the antioxidant group had significantly lower levels of inflammatory markers at both early and late time points, P < .05. Antioxidant treatment was associated with decreased measure of hypermetabolism, P < .05. Morbidity and mortality were not significantly different between groups. Length of hospital stay was significantly shorter in the antioxidant group when adjusted for patient demographics and injury characteristics (risk ratio (RR), 0.78; 95% confidence interval (CI), 0.66-0.92). In the antioxidant group, while infections were not different, the last positive culture post-injury was documented at median 19 days (Interquartile range (IQR), 11-43 days) compared with controls at 35 days (IQR, 15-59 days), P = .012. Patients receiving antioxidant and trace element supplementation had reduced markers of burn stress-induced inflammation; they were also associated with a decreased hypermetabolic response, shorter length of stay, and improved bacterial clearance.

Wound Coverage Technologies in Burn Care: Established Techniques.

Major advances in burn care have reduced post-burn morbidity and mortality. The development and incorporation of new wound healing modalities into the clinical arena have contributed to this improvement by allowing standard-of-care regimens to be established. These regimens range from early excision to the use of cultured epithelial autograft. Here, we review the wound care options that are now well established and used by many burn surgeons.

Comparison of two-dimensional methods versus three-dimensional scanning systems in the assessment of total body surface area estimation in burn patients.

BACKGROUND: Accurate measurement of percent total body surface area (%TBSA) burn is crucial in the management of burn patients for calculating the estimated fluid resuscitation, determining the need to transfer to a specialized burn unit and probability of mortality. %TBSA can be estimated using many methods, all of which are relatively inaccurate. Three-dimensional (3D) systems have been developed to improve %TBSA calculation and consequently optimize clinical decision-making. The objective of this study was to compare the accuracy of percent total burn surface area calculation by conventional methods against novel 3D methods. METHODS: This prospective cohort study included all acute burn patients admitted in 2016 who consented to participate. The staff burn surgeon determined the %TBSA using conventional methods. In parallel, a researcher determined 3D %TBSA using the BurnCase 3D program (RISC Software GmbH, Hagenberg, Austria). Demographic data and injury characteristics were also collected. Wilcoxon Signed Rank test was used to determine differences between each measure of %TBSA, with assessment of the influence of body mass index (BMI) and gender on accuracy. RESULTS: Thirty-five patients were included in the study (6 female and 29 male). Average age was 47.5 years, with a median BMI of 26.6kg/m2. %TBSA determined by BurnCase 3D program was statistically significantly different from conventional %TBSA assessment (p=0.007), with the %TBSA measured using Burn Case 3D being lower than the %TBSA determined using conventional means (Lund and Browder Diagram) by 1.3% (inter-quartile range -0.6% to 5.6%). BMI and gender did not have an impact on the estimation of the %TBSA. CONCLUSION: The BurnCase 3D program underestimated %TBSA by 1.3%, as compared to conventional methods. Although statistically significant, this difference is not clinically significant as it has minimal impact on fluid resuscitation and on the decision to transfer a patient to a burn unit. 3D %TBSA evaluation systems are valid tools to estimate %TBSA, and should therefore be considered to improve %TBSA estimation at centers with no available experienced burn staff surgeon. Their use may ultimately prevent inappropriate transfers and allow for improved management of patients with acute burns.
