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

OBJECTIVE: To assess the association of burn size and community participation as measured by the LIBRE Profile. SUMMARY OF BACKGROUND DATA: Burn size is an established clinical predictor of survival after burn injury. It is often a factor in guiding decisions surrounding early medical interventions; however, literature is inconclusive on its relationship to quality of life outcomes. METHODS: This is a secondary data analysis of a cross-sectional survey of adult burn survivors. Self-reported data were collected between October 2014 and December 2015 from 601 burn survivors aged ≥18 years with ≥5% total body surface area (TBSA) or burns to critical areas. Sociodemographic characteristics were compared between participants with small burns (≤40% TBSA burned) and large burns (>40% TBSA burned). Ordinary least squares regression models examined associations between burn size and LIBRE Profile scale scores with adjustments for sex, current work status, burns to critical areas, and time since burn injury. RESULTS: The analytic sample comprised 562 participants with data available for burn size. 42% of respondents had large burns (>40% TBSA burned) and 58% reported smaller burns (TBSA ≤40%). In adjusted regression models, patients with large burns tended to score lower on the Social Activities and Work & Employment scales ( P < 0.05) and higher on the Family & Friends scale ( P < 0.05). Participants with burns >40% TBSA scored lower for several individual items in the Social Activities scale and one item in the Work & Employment scale ( P < 0.05). CONCLUSIONS: Increasing burn size was found to be negatively associated with selected items of Work & Employment and Social Activities, but positively associated with aspects of Family & Friend Relationships. Future longitudinal studies are necessary to assess and understand the long-term social impact of burn injuries on adult populations.

Update on Severe Burn Management for the Intensivist.

Thermal injury of humans causes arguably the most severe perturbations in physiology that can be experienced. These physiologic derangements start immediately and can persist in some form until months or even years after the burn wounds are healed. Burn shock, marked activation of the systemic inflammatory response, multiple-organ failure, infection, and wound failure are just a few of the insults that may require management by the intensivist. The purpose of this article is to review recent advances in the critical care management of thermally injured patients.

Military Burn Care and Burn Disasters.

Mass-casualty incidents can occur because of natural disasters; industrial accidents; or intentional attacks against civilian, police, or in case of combat, military forces. Depending on scale and type of incident, burn casualties often with a variety of concomitant injuries can be anticipated. The treatment of life-threatening traumatic injuries should take precedent but the stabilization, triage, and follow-on care of these patients will require local, state, and often regional coordination and support.

Early serum (1→3)-ß-D-glucan levels in patients with burn injury.

Serum (1→3)-ß-D-glucan (BG) is increasingly used as diagnostic marker for invasive fungal infections. Exposure to gauze may lead to false-positive BG assays. The role of BG is unclear in thermally injured patients who frequently require extensive gauze coverage; therefore, we prospectively evaluated BG levels in burn-injured patients. Serum BG levels were measured in 18 burn patients immediately before application of the first dressing and 12 h after. Patients were stratified by extent of total body surface area (TBSA) requiring gauze coverage: <20%, 20-39%, 40-60% and >60%. BG levels were obtained from patients with non-burn trauma as controls. BG results were positive (>80 pg ml⁻¹) in 9/18 (50%) patients at baseline and in 8/18 (44%) 12 h after application of the first dressing. BG levels were positive in 1/5 (20%) of patients with <20% TBSA requiring gauze and in 10/13 (77%) with ≥ 20% (P < 0.05). None of the control patients had positive BG at any time point and none of the patients had candidemia at baseline. Mean serum BG levels decreased (19.44 pg ml⁻¹) after gauze placement. False-positive serum BG elevations are common in this patient population. Positivity correlates with extent of TBSA injured, but is not impacted by the gauze itself.

Incidence of methemoglobinemia in patients receiving cerium nitrate and silver sulfadiazine for the treatment of burn wounds: a burn center's experience.

In 1976, the combination of cerium nitrate and silver sulfadiazine was introduced as a topical therapy for burn wounds. Experience with a locally prepared combination agent has shown physical change of the eschar and delayed subeschar bacterial colonization. A potential systemic complication of this treatment is the development of methemoglobinemia (Met-Hba) due to the oxidizing nature of Ce(NO(3))(3). Met-Hba has a spectrum of clinical consequences, ranging from headache and cyanosis to cardiac ischemia, hypotension, and even death. Given the frequent use of this combination agent at our burn center, a retrospective review was conducted to evaluate the incidence of Met-Hba. A query of pharmacy records revealed 170 patients from January 2005 to October 2009 that had received this treatment. Eighteen patients (∼10%) developed Met-Hba as noted on arterial blood gas (methemoglobin>3%) and only three patients (∼2%) had methemoglobin levels >10%. In the majority of cases, there were no clinical symptoms of Met-Hba. Most patients' relative hypoxia resolved with cessation of treatment; however, five patients required treatment with methylene blue. The presence of Met-Hba associated with this topical therapy can be diagnosed early by vigilant monitoring, thereby reducing morbidity and mortality. In our experience, cerium combined with silver sulfadiazine is a valuable and safe treatment for deep partial and full-thickness burn wounds.

Actionable, Revised (v.3), and Amplified American Burn Association Triage Tables for Mass Casualties: A Civilian Defense Guideline.

Burn care remains among the most complex of the time-sensitive treatment interventions in medicine today. An enormous quantity of specialized resources are required to support the critical and complex modalities needed to meet the conventional standard of care for each patient with a critical burn injury. Because of these dependencies, a sudden surge of patients with critical burn injuries requiring immediate and prolonged care following a burn mass casualty incident (BMCI) will place immense stress on healthcare system assets, including supplies, space, and an experienced workforce (staff). Therefore, careful planning to maximize the efficient mobilization and rational use of burn care resources is essential to limit morbidity and mortality following a BMCI. The U.S. burn care profession is represented by the American Burn Association (ABA). This paper has been written by clinical experts and led by the ABA to provide further clarity regarding the capacity of the American healthcare system to absorb a surge of burn-injured patients. Furthermore, this paper intends to offer responders and clinicians evidence-based tools to guide their response and care efforts to maximize burn care capabilities based on realistic assumptions when confronted with a BMCI. This effort also aims to align recommendations in part with those of the Committee on Crisis Standards of Care for the Institute of Medicine, National Academies of Sciences. Their publication guided the work in this report, identified here as "conventional, contingency, and crisis standards of care." This paper also includes an update to the burn Triage Tables- Seriously Resource-Strained Situations (v.2).

Efforts to catalogue non-governmental organizations with a role in global burn relief.

INTRODUCTION: Non-governmental organizations (NGOs) have been instrumental in the treatment of traumatic injuries, including burns, particularly in low- and middle-income counties. The purpose of this project was to catalogue burn injury related NGO activities, describe coordinated efforts, and provide insight to burn health care professionals seeking volunteer opportunities. METHODS: Eligible burn NGOs were identified through internet searches, literature reviews, and social media. The organizations' websites were reviewed for eligibility and contact was attempted to confirm details. Global health organizations, including the World Health Organization, were consulted for their viewpoints. RESULTS: We identified 27 unique NGOs working in the area of burn care in African countries, all with differing missions, capacities, recruitment methods, and ability to respond to disaster. We also describe 14 global NGOs, some of which accept volunteers. Some NGOs were local, while others were headquartered in western countries. CONCLUSIONS: To our knowledge, this is the first effort towards the establishment of a Burn-NGO catalogue. Challenges included: frequent shifts in geographical regions supported, lack of collaboration among organizations, availability of public information, and austere environments. We invite collaborators to assist in the creation of a comprehensive, interactive and complete catalogue.

Using ordinal logistic regression to evaluate the performance of laser-Doppler predictions of burn-healing time.

BACKGROUND: Laser-Doppler imaging (LDI) of cutaneous blood flow is beginning to be used by burn surgeons to predict the healing time of burn wounds; predicted healing time is used to determine wound treatment as either dressings or surgery. In this paper, we do a statistical analysis of the performance of the technique. METHODS: We used data from a study carried out by five burn centers: LDI was done once between days 2 to 5 post burn, and healing was assessed at both 14 days and 21 days post burn. Random-effects ordinal logistic regression and other models such as the continuation ratio model were used to model healing-time as a function of the LDI data, and of demographic and wound history variables. Statistical methods were also used to study the false-color palette, which enables the laser-Doppler imager to be used by clinicians as a decision-support tool. RESULTS: Overall performance is that diagnoses are over 90% correct. Related questions addressed were what was the best blood flow summary statistic and whether, given the blood flow measurements, demographic and observational variables had any additional predictive power (age, sex, race, % total body surface area burned (%TBSA), site and cause of burn, day of LDI scan, burn center). It was found that mean laser-Doppler flux over a wound area was the best statistic, and that, given the same mean flux, women recover slightly more slowly than men. Further, the likely degradation in predictive performance on moving to a patient group with larger %TBSA than those in the data sample was studied, and shown to be small. CONCLUSION: Modeling healing time is a complex statistical problem, with random effects due to multiple burn areas per individual, and censoring caused by patients missing hospital visits and undergoing surgery. This analysis applies state-of-the art statistical methods such as the bootstrap and permutation tests to a medical problem of topical interest. New medical findings are that age and %TBSA are not important predictors of healing time when the LDI results are known, whereas gender does influence recovery time, even when blood flow is controlled for.The conclusion regarding the palette is that an optimum three-color palette can be chosen 'automatically', but the optimum choice of a 5-color palette cannot be made solely by optimizing the percentage of correct diagnoses.

Challenges to the Standardization of Burn Data Collection: A Call for Common Data Elements for Burn Care.

The use of common data elements (CDEs) is growing in medical research; CDEs have demonstrated benefit in maximizing the impact of existing research infrastructure and funding. However, the field of burn care does not have a standard set of CDEs. The objective of this study is to examine the extent of common data collected in current burn databases.This study examines the data dictionaries of six U.S. burn databases to ascertain the extent of common data. This was assessed from a quantitative and qualitative perspective. Thirty-two demographic and clinical data elements were examined. The number of databases that collect each data element was calculated. The data values for each data element were compared across the six databases for common terminology. Finally, the data prompts of the data elements were examined for common language and structure.Five (16%) of the 32 data elements are collected by all six burn databases; additionally, five data elements (16%) are present in only one database. Furthermore, there are considerable variations in data values and prompts used among the burn databases. Only one of the 32 data elements (age) contains the same data values across all databases.The burn databases examined show minimal evidence of common data. There is a need to develop CDEs and standardized coding to enhance interoperability of burn databases.

District of Columbia Emergency Healthcare Coalition Burn Mass Casualty Plan: Development to Exercise Date.

The District of Columbia Emergency Healthcare Coalition (DC EHC) brought together a Burn Task Force to tackle the issue of mass burn care in a metropolitan area in light of limited local burn center resources. This article outlines the development of the mass burn care plan. Using a tiered treatment approach, mass burn victims would be transported first to burn centers within the area, followed by nonburn center trauma centers, and finally to nonburn and nontrauma center acute care facilities. Once activated the Burn Task Force would triage and coordinate transfer of mass burn patients within the District for further care at burn centers using a strong link with the Eastern Regional Burn Disaster Consortium. This plan was exercised in the spring of 2014 to test all of the components. To strengthen mass burn care, this plan, put in place for the District of Columbia, has been expanded to include the National Capital Region as well.

A Survey of Mechanical Ventilator Practices Across Burn Centers in North America.

Burn injury introduces unique clinical challenges that make it difficult to extrapolate mechanical ventilator (MV) practices designed for the management of general critical care patients to the burn population. We hypothesize that no consensus exists among North American burn centers with regard to optimal ventilator practices. The purpose of this study is to examine various MV practice patterns in the burn population and to identify potential opportunities for future research. A researcher designed, 24-item survey was sent electronically to 129 burn centers. The χ, Fisher's exact, and Cochran-Mantel-Haenszel tests were used to determine if there were significant differences in practice patterns. We analyzed 46 questionnaires for a 36% response rate. More than 95% of the burn centers reported greater than 100 annual admissions. Pressure support and volume assist control were the most common initial MV modes used with or without inhalation injury. In the setting of Berlin defined mild acute respiratory distress syndrome (ARDS), ARDSNet protocol and optimal positive end-expiratory pressure were the top ventilator choices, along with fluid restriction/diuresis as a nonventilator adjunct. For severe ARDS, airway pressure release ventilation and neuromuscular blockade were the most popular. The most frequently reported time frame for mechanical ventilation before tracheostomy was 2 weeks (25 of 45, 55%); however, all respondents reported in the affirmative that there are certain clinical situations where early tracheostomy is warranted. Wide variations in clinical practice exist among North American burn centers. No single ventilator mode or adjunct prevails in the management of burn patients regardless of pulmonary insult. Movement toward American Burn Association-supported, multicenter studies to determine best practices and guidelines for ventilator management in burn patients is prudent in light of these findings.

The Pentagon attack of September 11, 2001: a burn center's experience.

On September 11, 2001, an airplane flown by terrorists crashed into the Pentagon, causing a mass casualty incident with 189 deaths and 106 persons treated for injuries in local hospitals. Nine burn victims and one victim with an inhalation injury only were transported to the burn center hospital. The Burn Center at Washington Hospital Center admitted and treated the acute burn patients while continuing its mission as the regional burn center for the Washington DC region. Eight of the nine burn patients survived. Lessons learned include 1) A large-volume burn center hospital can absorb nine acute burns and maintain burn center and hospital operations, but the decision to keep or transfer burn patients must be tempered with the reality that several large burns can double or triple the work load for 2 to 3 months. 2) Transfer decisions should have high priority and be timely to ensure optimum care for the patients without need for movement of medical personnel from one burn center to another. 3) The reserve capacity of burn beds in the United States is limited, and the burn centers and the American Burn Association must continue to seek recognition and support from Congress and the federal agencies for optimal preparedness.

What's in a Name? Recent Key Projects of the Committee on Organization and Delivery of Burn Care.

The Committee for the Organization and Delivery of Burn Care (ODBC) was charged by President Palmieri and the American Burn Association (ABA) Board of Directors with presenting a plenary session at the 45th Meeting of the ABA in Palm Springs, CA, in 2013. The objective of the plenary session was to inform the membership about the wide range of the activities performed by the ODBC committee. The hope was that this session would encourage active involvement within the ABA as a means to improve the delivery of future burn care. Selected current activities were summarized by key leaders of each project and highlighted in the plenary session. The history of the committee, current projects in disaster management, regionalization, best practice guidelines, federal partnerships, product development, new technologies, electronic medical records, and manpower issues in the burn workforce were summarized. The ODBC committee is a keystone committee of the ABA. It is tasked by the ABA leadership with addressing and leading progress in many areas that constitute current challenges in the delivery of burn care.

Serum lactate, not base deficit, rapidly predicts survival after major burns.

BACKGROUND: Clinical studies document correlation of serum lactate and base deficit with mortality in trauma and sepsis. No study of the prognostic value of these two serum markers has been reported in burn injury. METHODS: Resuscitation data from 49 patients admitted to the adult Burn ICU were analyzed. Lactate and base deficit were analyzed upon admission and every 2h during the initial 48 h after admission. Resuscitation was managed per standard routine, blinded to these data, guided by the Parkland formula. Initial statistical analysis with Cox's regression model was used to determine the relationship between survival, resuscitation parameters, and demographics. Then, a logistic regression was used to determine if any of these variables were quickly predictive (initial values) of the risk of death. RESULTS: Two variables were predictive of mortality by the Cox regression model: (1) serum lactate value and (2) patient age. Furthermore, analysis by logistic regression revealed that the initial serum lactate value was separately predictive of mortality. CONCLUSION: In this study, serum lactate but not base deficit, was a predictor of mortality following major burns. Moreover, initial serum lactate values were also predictive of mortality separately.

The 2003 Carl A Moyer Award: real-time metabolic monitors, ischemia-reperfusion, titration endpoints, and ultraprecise burn resuscitation.

Real-time metabolic monitoring of varied vascular beds provides the raw data necessary to conduct ultraprecise burn shock resuscitation based on second-by-second assessment of regional tissue perfusion. It also illustrates shortcomings of current clinical practices. Arterial base deficit was continuously monitored during 11 clinical resuscitations of patients suffering burn shock using a Paratrend monitor. Separately, in a 30% TBSA rat burn model (N = 70), three Paratrend monitors simultaneously recorded arterial blood gas and tissue pCO2 of the burn wound and colonic mucosa during resuscitation at 0, 2, 4, 6, and 8 ml/kg/%TBSA. Paratrend data were analyzed in conjunction with previously reported laser Doppler images of actual burn wound capillary perfusion. With current clinical therapy, continuous monitoring of arterial base deficit revealed repetitive cycles of resolution/worsening/resolution during burn shock resuscitation. In the rat model, tissue pCO2 in both burn wounds and splanchnic circulation differed depending on the rate of fluid resuscitation (P <.01 between sham and 0 ml/kg/%TBSA and between 2 ml/kg/%TBSA and 4 ml/kg/%TBSA). Burn wound pCO2 values correlated well with laser Doppler determination of actual capillary perfusion (rho = -.48, P <.01). The following conclusions were reached: 1). Gratuitous and repetitive ischemia-reperfusion-ischemia cycles plague current clinical therapy as demonstrated by numerous "false starts" in the resolution of arterial base deficit; 2). in a rat model, real-time monitoring of burn wound and splanchnic pCO2 demonstrate a dose-response relationship with rate of fluid administration; and 3). burn wound and splanchnic pCO2 are highly correlated with direct measurement of burn wound capillary perfusion by laser Doppler imager. Either technique can serve as a resuscitation endpoint for real-time feedback-controlled ultraprecise resuscitation.
