Abstract Background Previous reports individually identified different factors that predict death after burns. The authors employed the multi-center American Burn Association’s (ABA) National Burn Repository (NBR) to elucidate which parameters have the highest negative impact on burn mortality. Methods We audited data from the NBR v8.0 for the years 2002–2011 and included 137,061 patients in our study. The cases were stratified into two cohorts based on the primary outcome of death/survival and then evaluated for demographic data, intraoperative details, and their morbidity after admission. A multivariable regression analysis aimed to identify independent risk factors associated with mortality. Results A total of 3.3% of patients in this analysis did not survive their burn injuries. Of those, 52.0% expired within 7 days after admission. Patients in the mortality cohort were of older age (p < 0.001), more frequently female (p < 0.001), and had more pre-existing comorbidities (p < 0.001). Total body surface area (TBSA), inhalation injury, hospitalization time, and occurrence of complications were higher compared to survivors (p < 0.001). Lack of insurance (odds ratio (OR) = 1.84, confidence interval (CI) 1.38–2.46), diabetes (OR = 1.24, CI 1.01–1.53), any complication (OR = 4.09, CI 3.27–5.12), inhalation injury (OR = 3.84, CI 3.38–4.36), and the need for operative procedures (OR = 2.60, CI 2.20–3.08) were the strongest independent contributors to mortality after burns (p < 0.001). Age (OR = 1.07, CI 1.06–1.07) and TBSA (OR = 1.09, CI 1.09–1.09) were significant on a continuous scale (p < 0.001) while overall comorbidities were not a statistical risk factor. Conclusion Uninsured status, inhalation injury, in-hospital complications, and operative procedures were the strongest mortality predictors after burns. Since most fatal outcomes (52.0%) occur within 7 days after injury, physicians and medical staff need to be aware of these risk factors upon patient admission to a burn center.

Abstract This study establishes important, national benchmarks for burn centers to assess length of stay (LOS) and number of procedures across patient profiles. We examined the relationship between patient characteristics such as age and total body surface area (TBSA) burned and number of procedures and LOS in the United States, using the American Burn Association National Burn Repository (NBR) database version 8.0 (2002–2011). Among 21,175 surviving burn patients (TBSA > 10–60%), mean age was 33 years, and mean injury size was 19.9% TBSA. Outcomes included the number of debridement, excision, autograft procedures, and LOS. Independent variables considered were: age (linear, squared, and cubed to account for nonlinearity), TBSA, TBSAs of partial-thickness and mixed/full-thickness burns, sex, hospital-acquired infection, other infection, inhalation injury, and diabetes status. Regression methods included a mixed-effects model for LOS and ordinary least squares for number of procedures. A backward stepwise procedure (P <0.2) was used to select variables. Number of excision and autografting procedures increased with TBSA; however, this relationship did not hold for debridement. After adjusting for sex, age, and comorbidities, predicted LOS for adults (18+) was 12.1, 21.7, 32.2, 43.7, and 56.1 days for 10, 20, 30, 40, and 50% TBSA, respectively. Similarly, predicted LOS for pediatrics (age < 18) was 8.1, 18.8, 33.2, 47.6, and 56.1 days for the same TBSA groups, respectively. While average estimates for adults (1.12 days) and pediatrics (1.01) are close to the one day/TBSA rule-of-thumb, consideration of other important patient and burn features in the NBR can better refine predictions for LOS.

Risk factors of mortality in burn patients such as inhalation injury, patient age, and percent of total body surface area (%TBSA) burned have been identified in previous publications. However, little is known about the variability of mortality outcomes between burn centers and whether the admitting facilities or facility volumes can be recognized as predictors of mortality. De-identified data from 87,665 acute burn observations obtained from the National Burn Repository between 2003 and 2007 were used to estimate a multivariable logistic regression model that could predict patient mortality with reference to the admitting burn facility/facility volume, adjusted for differences in age, inhalation injury, %TBSA burned, and an additional factor, percent full thickness burn (%FTB). As previously reported, all three covariates (%TBSA burned, inhalation injury, and age) were found to be highly statistically significant risk factors of mortality in burn patients (P value < 0.0001). The additional variable, %FTB, was also found to be a statistically significant determinant, although it did not greatly improve the multivariable model. The treatment/admitting facility was found to be an independent mortality predictor, with certain hospitals having increased odds of death and others showing a protective effect (decreased odds ratio). Hospitals with high burn volumes had the highest risk of mortality. Mortality outcomes of patients with similar risk factors (%TBSA burned, inhalation injury, age, and %FTB) are significantly affected by the treating facility and their admission volumes.

Abstract Objectives Studies suggest that a restrictive transfusion strategy is safe in burns, yet the efficacy of a restrictive transfusion policy in massive burn injury is uncertain. Our objective: compare outcomes between massive burn (≥60% total body surface area (TBSA) burn) and major (20–59% TBSA) burn using a restrictive or a liberal blood transfusion strategy. Methods Patients with burns ≥20% were block randomized by age and TBSA to a restrictive (transfuse hemoglobin &lt;7 g/dL) or liberal (transfuse hemoglobin &lt;10 g/dL) strategy throughout hospitalization. Data collected included demographics, infections, transfusions, and outcomes. Results Three hundred and forty-five patients received 7,054 units blood, 2,886 in massive and 4,168 in restrictive. Patients were similar in age, TBSA, and inhalation injury. The restrictive group received less blood (45.57 ± 47.63 vs. 77.16 ± 55.0, p &lt; 0.03 massive; 11.0 ± 16.70 vs. 16.78 ± 17.39, p &lt; 0.001) major). In massive burn, the restrictive group had fewer ventilator days (p &lt; 0.05). Median ICU days and LOS were lower in the restrictive group; wound healing, mortality, and infection did not differ. No significant outcome differences occurred in the major (20–59%) group (p &gt; 0.05). Conclusions: A restrictive transfusion strategy may be beneficial in massive burns in reducing ventilator days, ICU days and blood utilization, but does not decrease infection, mortality, hospital LOS or wound healing.

Background: Invasive candidiasis (IC) is a major cause of morbidities and mortality in patients hospitalized with major burns. This study investigated the incidence of IC in this specific population and analyzed the possible risk factors. Materials and Methods: We retrospectively analyzed data from the National Health Insurance Research Database (NHIRD) of Taiwan. We identified 3582 patients hospitalized with major burns on over 20% of their total body surface area (TBSA) during 2000–2013; we further analyzed possible risk factors. Result: IC was diagnosed in 452 hospitalized patients (12.6%) with major burns. In the multivariate analysis, patients older than 50 years (adjusted odds ratio (OR) = 1.96, 95% confidence interval (CI) 1.36–2.82), those of female sex (adjusted OR = 1.33, 95% CI 1.03–1.72), those with burns on the head (adjusted OR = 1.33, 95% CI 1.02–1.73), and those with burns over a greater TBSA had higher risks of IC. Conclusion: Treating IC is crucial in healthcare for major burns. Our study suggests that several risk factors are associated with IC in patients hospitalized with major burns, providing reliable reference value for clinical decisions.

Background Acute kidney injury (AKI) is one of the most severe complications of burn injury. AKI with severe burn injury causes high mortality. This study aims to investigate the incidence of and predisposing factors for AKI in burn patients. Methods This is a single-center, retrospective, descriptive criterion standard study conducted from June 27, 2015, to March 8, 2016. We used Kidney Disease Improving Global Outcomes criteria to define and select patients with AKI. The study was conducted by recruiting in hospital patients who suffered from the flammable cornstarch-based powder explosion and were treated under primary care procedures. A total of 49 patients who suffered from flammable dust explosion-related burn injury were enrolled and admitted on June 27, 2015. The patients with more than 20% total body surface area of burn were transferred to the intensive care unit. Patients received fluid resuscitation in the first 24 hours based on the Parkland formula. The primary measurements were the incidence of and predisposing factors for AKI in these patients. Demographic characteristics, laboratory data, and inpatient outcomes were also evaluated. The incidence of AKI in this cohort was 61.2% (n = 30). The mortality rate was 2.0% (n = 1) during a 59-day follow-up period. The multivariate analysis revealed inhalation injury (adjusted OR = 22.0; 95% CI [1.4–358.2]) and meeting ≥3 American Burn Association (ABA) sepsis criteria (adjusted OR = 13.7; 95% CI [1.7–110.5]) as independent risk factors for early advanced AKI. Conclusions The incidence rate of AKI was higher in this cohort than in previous studies, possibly due to the flammable dust explosion-related burn injury. However, the mortality was lower than that expected. In clinical practice, indicators of inflammation, including ABA sepsis criteria may help in predicting the risk of AKI in patients with burn injury.

Abstract Introduction Burn care in the United States takes place primarily in tertiary care centers with specialty-focused burn capabilities. Patients are often initially transported to centers without burn capabilities, requiring subsequent transfer to a higher level of care. This study aims to evaluate the effect of this treatment delay on outcomes. Methods Under IRB approval, adult burn patients meeting American Burn Association (ABA) criteria for transfer at a single burn center were retrospectively identified. Cohorts were divided into patients who were initially taken to a non-burn center and subsequently transferred versus patients taken immediately to a burn center. Outcomes between the groups were compared. Results A total of 122 patients were identified, 61 in each cohort. There was no difference between the transfer and direct admit cohorts with respect to median age (52 vs. 46, p = 0.45), percent total body surface area burn (10% vs. 10%, p = 0.08), concomitant injury (0 vs. 4, p = 0.12), or intubation prior to admission (5 vs. 7, p = 0.76). Transfer patients experienced a longer median time from injury to burn center admission than directly admitted patients (1 vs. 8 hours, p &lt; 0.01). Directly admitted patients were more likely to have inhalation burn (18 vs. 4, p &lt; 0.01), require intubation after admission (10 vs. 2, p = 0.03), require an emergent procedure (18 vs. 5, p &lt; 0.01), and develop infectious complications (14 vs. 5, p = 0.04). However, there was no difference between transfers and direct admits in ventilator days (9 vs. 3 days, p = 0.37), number of operations (0 vs. 0, p = 0.16), length of stay (3 vs. 3 days, p = 0.44), or mortality (6 vs. 3, p = 0.50). Conclusions This study suggests that significantly injured, hemodynamically unstable patients were more likely to be immediately identified and taken directly to a burn center. Patients who otherwise met ABA criteria for transfer were not affected by short delays in transfer to definitive burn care. Applicability of Research to Practice Initial triage and evaluation of hemodynamically stable patients at non-burn centers does not negatively impact outcomes in patients who meet ABA criteria for transfer to a burn center.

Background Pediatric head and neck burns (HNBs) require special attention due to the potential for long-term disfigurement, functional impairment, and psychosocial stigma. Methods We performed a retrospective review of patients <18 years old admitted to Grady Memorial Hospital with a diagnosis of HNB from 2009-2017. Demographic data, burn characteristics, management, and hospital course were analyzed. Results Of the 272 patients included, 65.4% were male with a mean age of 63.2 months. Burn mechanism was primarily secondary to scalding liquids (70.2%) or flames (23.9%). The average total body surface area involved was 10.3%, and 3.0% for the head/neck. Average length of stay was 5.2 days and overall mortality was 1.1%. Twenty-five patients (9.2%) required surgery in the acute setting, and 5 (1.8%) required secondary surgery for hypertrophic scarring or contracture. Discussion Pediatric HNBs occur most commonly in males <6 years old secondary to scalding liquids or open flames. Most patients can be managed nonoperatively without long-term sequelae.

Abstract Inhalation injury causes significant morbidity and mortality secondary to compromise of the respiratory system as well as systemic effects limiting perfusion and oxygenation. Nebulized heparin reduces fibrin cast formation and duration of mechanical ventilation in patients with inhalation injury. To date, no study has compared both dosing strategies of 5000 and 10,000 units to a matched control group. This multicenter, retrospective, case-control study included adult patients with bronchoscopy-confirmed inhalation injury. Each control patient, matched according to age and percent of total body surface area, was matched to a patient who received 5000 units and a patient who received 10,000 units of nebulized heparin. The primary endpoint of the study was duration of mechanical ventilation. Secondary endpoints included 28-day mortality, ventilator-free days in the first 28 days, difference in lung injury scores, length of hospitalization, incidence of ventilator-associated pneumonia, and rate of major bleeding. Thirty-five matched patient trios met inclusion criteria. Groups were well-matched for age (P = .975) and total body surface area (P = .855). Patients who received nebulized heparin, either 5000 or 10,000 units, had 8 to 11 less days on the ventilator compared to controls (P = .001). Mortality ranged from 3 to 14% overall and was not statistically significant between groups. No major bleeding events related to nebulized heparin were reported. Mechanical ventilation days were significantly decreased in patients who received 5000 or 10,000 units of nebulized heparin. Nebulized heparin, either 5000 units or 10,000 units, is a safe and effective treatment for inhalation injury.

Abstract Background It is well known that the HIV epidemic and COVID-19 pandemic have both disproportionately harmed marginalized minority and immigrant communities in the United States. The risk factors associated with disease incidence and outcomes reaffirm that structural vulnerabilities—sociopolitically imposed risk factors like discrimination, legal status, poverty, and beyond which impact a patient’s opportunity to achieve optimal health—play a key role in facilitating the inequitable harms of COVID-19 and HIV alike. This study explores the role of structural forces in increasing the risk of SARS-CoV-2 coinfection among people with HIV (PWH). Methods We performed a retrospective chart review of PWH receiving care at the University of Nebraska Medical Center HIV clinic in Omaha, Nebraska, to collect patient demographics, comorbidities, HIV outcomes, and COVID-19 outcomes for 37 patients with HIV and SARS-CoV-2 coinfection as of August 27, 2020. As a comparison group, we obtained demographic data from a registry of all patients seen at the HIV clinic. We used R Statistical Software to perform descriptive statistical analysis. Results Relative to our overall HIV clinic population, over twice as many Hispanic patients (35.1% vs. 16.0%), three times as many undocumented patients (13.5% vs. 4.2%), and four times as many refugee patients (16.2% vs. 4.0%) had COVID-19. The majority (67.6%) of coinfected patients reported working in “essential” jobs during the pandemic. Thirty-four of the 37 people with HIV and COVID-19 (PWHC) had at least one comorbidity, including increased BMI (83.7%), hypertension (64.9%), or hyperlipidemia (48.6%). All 37 PWHC remained alive as of October 4, 2020. Demographics and HIV Disease Progression of People with HIV and SARS-CoV-2 Coinfection vs. Overall HIV Clinic Registry Demographics and HIV Disease Progression of People with HIV and SARS-CoV-2 Coinfection vs. Overall HIV Clinic Registry (continued) Conclusion The disproportionate burden of SARS-CoV-2 coinfection on Hispanic, undocumented, and refugee PWH may be a product of structural vulnerabilities contributing to greater risk of exposure. Although all 37 PWHC had well-controlled HIV and relatively mild COVID-19 courses, the broader theme of disproportionate COVID-19 incidence among vulnerable sub-populations of people with HIV reaffirms the importance of structural interventions to mitigate current and downstream harms.

Abstract Introduction Estimates on frequency and outcomes of burn or inhalation injury in the United States are limited since reported databases are confined to specific phases of care, included facilities, length of follow-up, facility/provider/patient identification and/or lack of longitudinal tracking. A population-based database addresses these issues. Methods We queried a statewide mandated-reporting database for the years from 2000 through 2015 at the time of injury using a set of ICD9-CM codes for second degree or deeper burns, inhalation injury, and chemical and electrical burns. Burn total body surface area percentage by anatomical region was assigned as appropriate using modified and age-stratified Lund and Browder charts. Records for each patient were extracted out to one year pre- and post-injury, as available. Provider and facility burn volume and survival was stratified into quartiles. We applied the Committee on Trauma/American Burn Association referral criteria to the index presentation. Kaplan-Meier curves were generated to 1-year post injury for testing combinations of burn percent total body surface area of 20% and inhalation injury for age ranges &lt; 15, 15 - 60, and &gt;60 years. Regression models were developed to model the probabilities of in-patient, 90-day, and 365-day mortality and readmission. Results 56,712 patients were included. Overall, 22% of patients meeting referral criteria were never seen at a burn center within 1-year post-injury. The greatest positive predictors of in-patient mortality were facility case volume and burn percent total body surface area. The greatest negative predictors were high provider burn case volume (for highest quartile, adjusted odds ratio 0.08, 95% confidence intervals 0.06 – 0.12). The highest risk of unscheduled 30-day readmission was associated with index presentation to a non-burn care facility (p &lt; 0.001). For all groups, the first 100 days had the greatest mortality rate, the most severe being among patients of age greater than 60 with &gt;20% burn percent total body surface area and inhalation injury, with a 40% survival rate. Conclusions This study is the first to be able to simultaneously evaluate in-patient, post-discharge, and facility-based parameters for outcomes. A significant number of patients are not accounted with current databases. Applicability of Research to Practice A population-based approach with longitudinal tracking allows for greater realization of the outcomes of all patients following burn injury. Existing association-supported or government databases fail to account for a significant portion of burn victims, motivating further evaluation of burn care efforts.
