ABSTRACT
The optimal treatment of burn shock is still unresolved. The problem of "fluid creep" continues despite modern devices that fail to improve outcomes over hourly urine output. Colloids, especially albumin, reduce fluid requirements. Albumin can be used either immediately at the start of resuscitation, or as a "rescue" when crystalloid use is excessive. Several studies confirm that when crystalloid resuscitation is "out of control" the majority of caregivers will add albumin to reduce fluid rates. A multi-center trial is underway comparing crystalloids with albumin to confirm the benefit of colloids. The next question is whether albumin or plasma is as the better colloid choice.

BACKGROUND: Survivors of burn injuries may be at risk of early death. This study describes the mortality of burn survivors in comparison with two matched cohorts. METHODS: This retrospective cohort study compared adults admitted with a burn injury from 2009 to 2019 with two matched cohorts; one from the general population and one with a diagnosis of acute pancreatitis. Patients were excluded from analysis if they died during hospital admission or within 90 days of hospital discharge. Cox proportional hazards models were used to explore differences between cohorts and variables associated with mortality. RESULTS: 7,147 burns patients were matched with 6,810 pancreatitis patients and 28,184 individuals from the general population. Patients with a burn injury had an increased risk of death when compared to the general population (HR 2.46, 95 % CI 2.28,2.66, p < 0.001) and those with acute pancreatitis (HR 1.28, 95 % CI 1.17,1.40, p < 0.001). Socioeconomic deprivation, increasing comorbidity and specific comorbidities such as alcohol, drug abuse and depression were also associated with increased mortality. CONCLUSION: Survivors of burn injury are at increased risk of mortality compared to individuals matched on sex, age and socioeconomic deprivation in both the general population and with a hospital admission due to acute pancreatitis.
ABSTRACT
Low-cost and efficient culture environments comparable to standard techniques would undoubtedly improve burn outcomes in under-resourced settings. The aim of this case series was to report on the CEA graft-take using a modified composite culture technique. CEA transplants, following emergency ethical approval, occurred for burn patients (n=25) with low survival prognosis and/or exhausted donor sites. Keratinocytes were retrieved from skin biopsies, seeded centrally on routinely-used dressing gauze and incubated at 37 °C in pediatric incubators. Fresh autogenous plasma was applied daily and hydrogel every third or fourth day. After confluence, the CEA was transplanted onto debrided wound beds. Xenografts were used for temporary cover during the culture period. Final graft take assessment (21 days) was assessed and calculated as a graft take percentage for total CEA area transplanted. Central indices were described as mean (95% CI) and frequency (%) for age, total body surface area, abbreviated burn severity index scores, survival prognosis and graft take. Eleven patients survived with a mean age of 36.1 years (95% CI 25.8-46.4), 45.0 %TBSA burns (95% CI 35.1-54.9), 9.7 ABSI scores (95% CI 8.6-10.8) and 79.5% graft take (95% CI 62.9-96.0). Reduced graft take (61.2%) was observed in patients with perineum burns and increased graft take (97%) in uncomplicated burns. The average CEA graft take was 79.5% using a low-cost culture technique and comparable to the largest case series in literature. The survival of the major burn cases was highly favourable considering injury severity, expected outcomes without CEA and the observed challenges.
ABSTRACT
Contact burns in children are not uncommon and are often due to accidental contact. Medico-legal assessment is of paramount importance in these contexts to identify cases of abuse. In three cases of burns caused by contact with radiators or a portable heater -two accidental and one deliberate- thorough medico-legal assessment, combined with on-site event reconstruction, enabled accurate diagnoses. Accidental burns displayed a 'pattern' compatible with the incandescent instrument but were more irregular, with different depths and in different parts of the body. In contrast, intentional burns were uniform in depth, distribution and localisation, inconsistent with accidental events. In this context, the on-site inspection and direct evaluation of the objects involved were crucial in the medico-legal assessment. These are indispensable elements for a thorough analysis and abuse recognition.
ABSTRACT
OBJECTIVES: To assess burn injury knowledge and its predictors among reproductive-age women attending an urban and a semi-rural hospital in Northwest Nigeria DESIGN: A descriptive cross-sectional study SETTING: It was conducted in the general and paediatric outpatient clinics of Aminu Kano Teaching Hospital in Kano (urban setting) and the general outpatient, paediatric outpatient and antenatal clinics of Federal Medical Centre Birnin Kudu (semi-rural setting). PARTICIPANT: In 2021, 362 women aged 18-44 years were randomly selected from clinic attendees over six weeks. Of them, 217 were from the urban hospital. Data regarding their sociodemographic characteristics and knowledge of burn injuries was collected using a pretested, semi-structured interviewer-administered questionnaire. OUTCOME MEASURE: Knowledge of burn injuries RESULTS: About 83.4 %, 77.1 % and 77.6 % of respondents had adequate general, primary prevention and overall knowledge of burn injuries, respectively. Their mean overall knowledge score was 18.6 out of 24, but only 55.5 % had adequate first-aid knowledge. The study sites did not significantly differ in burns first-aid, prevention and overall knowledge scores. However, urban respondents were more ignorant about the cause of burns and knew that burn injuries could be fatal. More semi-rural respondents knew that flames and chemicals cause burn injuries. Predictors of overall knowledge were age, educational level, number of children in their household, previously seeing a burn-injured child, and primary source of burns-related information. CONCLUSIONS: The proportion of respondents with adequate overall burn injury knowledge was high; however, knowledge gaps exist among them. Overall, their first-aid knowledge was relatively low. The urban and semi-rural respondents had no significant differences in first-aid, prevention, or overall knowledge of burn injuries. However, knowledge of the causes of burns and burn complications differed between the urban and semi-rural study locations. Therefore, the clinical settings of this study present opportunities for similar burn-related educational interventions.
ABSTRACT
BACKGROUND: Despite an increase in knowledge, blood loss during burn excisional surgery remains a major challenge and is an independent predictor of mortality. During burn surgery, limited measures are available to control the bleeding. Increased fibrinolysis could be one of the contributing factors of blood loss during burn excisional surgery. Tranexamic acid inhibits the fibrinolytic response, and a small body of evidence shows positive effects of tranexamic acid on the volume of blood loss. METHODS: The main objectives of this study are twofold, (1) to investigate whether tranexamic acid reduces blood loss and (2) to investigate the changes in coagulation after burn trauma and during burn excisional surgery. This study is a multicenter double-blind randomized clinical trial in patients scheduled for burn excisional surgery within the Dutch burn centers. All adult patients scheduled for burn surgery with an expected blood loss of ≥ 250 are eligible for inclusion in this study. The study is powered on a blood loss reduction of 25% in the intervention group. In total, 95 subjects will be included. The intervention group will receive 1500 mg tranexamic acid versus placebo in the other group. Primary endpoint is reduction of blood loss. Secondary endpoints include occurrence of fibrinolysis during surgery, graft take of the split skin graft, and differences in coagulation and blood clot formation. DISCUSSION: This protocol of a randomized controlled trial aims to investigate the efficacy of tranexamic acid in reducing blood loss during burn excisional surgery. Furthermore, this study aims to clarify the coagulation status after burn trauma and during the surgical process. TRIAL REGISTRATION: EudraCT: 2020-005405-10; ClinicalTrial.gov: NCT05507983 (retrospectively registered in August 2022, inclusion started in December 2021).

Objectives: Deep thermal injuries are among the most serious injuries in childhood, often resulting in scarring and functional impairment. However, accurate assessment of burn depth by clinical judgment is challenging. Optical coherence tomography (OCT) provides structural images of the skin and can detect blood flow within the papillary plexus. In this study, we determined the depth of the capillary network in healthy and thermally injured skin and compared it with clinical assessment. Methods: In 25 children between 7 months and 15 years of age (mean age 3.5 years (SD±4.14)) with thermal injuries of the ventral thoracic wall, we determined the depth of the capillary network using OCT. Measurements were performed on healthy skin and at the center of the thermal injury (16 grade IIa, 9 grade IIb). Comparisons were made between healthy skin and thermal injury. Results: The capillary network of the papillary plexus in healthy skin was detected at 0.33â¯mm (SD±0.06) from the surface. In grade IIb injuries, the depth of the capillary network was 0.36â¯mm (SD±0.06) and in grade IIa injuries 0.23â¯mm (SD±0.04) (Mann-Whitney U test: p<0.001). The overall prediction accuracy is 84â¯%. Conclusions: OCT can reliably detect and differentiate the depth of the capillary network in both healthy and burned skin. In clinical IIa wounds, the capillary network appears more superficial due to the loss of the epidermis, but it is still present in the upper layer, indicating a good prognosis for spontaneous healing. In clinical grade IIb wounds, the papillary plexus was visualized deeper, which is a sign of impaired blood flow.
ABSTRACT
Introduction: Burn injury is a major cause of mortality. Majority of the burns occur in low and middle-income countries like Uganda. Uganda has a limited number of burn centres and medical resources, making a predictor of mortality necessary in allocation of the limited resources. Although the revised Baux (r-Baux) score has been validated and used in many high income countries, no study has assessed its role in an African low-income country; the reason this study was done. Methods: This was a prospective multicentre cohort that enroled 101 burn patients with moderate and severe burns admitted in three tertiary hospitals in western Uganda. Follow-up was done until discharge, documenting mortality. A receiver operator characteristic curve was used to determine the role of r-Baux score in predicting mortality. Results: This study included 101 patients, with a mean age of 21.3 (SD=16.8) years. The majority of the participants were male (69.3%). The area under the curved for r-Baux score's prediction of mortality was 0.943 (P<0.001). The most appropriate cut-off was determined to be 74.5. At this cut-off, r-Baux score predicted mortality with a sensitivity of 100% and specificity of 83.5%. After controlling for burn severity using Poisson regression, a patient with r-Baux score greater than 74.5 was 1.358 times more likely to die (adjusted risk ratio=1.358, 95% CI=1.195-1.543, P<0.001). Conclusion: The r-Baux score was found to be excellent at predicting mortality among burn patients in Uganda and therefore should be done for all patients at admission, in order to predict mortality and do proper planning.
ABSTRACT
ETHNOPHARMACOLOGICAL RELEVANCE: Sea buckthorn (Hippophae rhamnoides L. ) has been designated a "medicine food homology" fruit by the National Health Commission of China due to its nutritional value. In traditional Chinese ethnomedicine, Hippophae rhamnoides L. is commonly used to treat nonhealing wounds such as burns, sores, and gastric ulcers. The aim of this study was to explore the healing effects of the ethyl acetate extract of sea buckthorn seeds (SBS-EF) on burn wounds. AIM OF THE STUDY: The primary objectives of this research were to determine the most effective medicinal site of action for treating burns with sea buckthorn seeds (SBS) and to investigate the underlying material basis and mechanisms of their therapeutic effects. MATERIALS AND METHODS: The effects of different components of SBS-EF on the proliferation and migration of human skin fibroblasts (HSFs) were evaluated via MTT assays, scratch assays, transwell assays, and hydroxyproline secretion analysis. SBS-EF displayed the greatest activity amongst the extracts. Subsequent analyses included network pharmacology methodology, molecular docking studies, ultraperformance liquid chromatography UPLC-Orbitrap-Exploris-120-MS and a severe second-degree burn rat model to investigate the chemical constituents and potential therapeutic mechanisms of the SBS-EF. RESULTS: In vitro studies demonstrated the efficacy of SBS-EF in promoting HSF growth and migration. UPLC-Orbitrap-Exploris-120-MS analysis revealed that SBS-EF had ten major constituents, with flavonoids being the predominant compounds, especially catechin, quercetin, and kaempferol derivatives. Network pharmacology and molecular docking analyses indicated that SBS-EF may exert its healing effects by modulating the Wnt/ß-catenin signalling pathway. Subsequent in vivo experiments demonstrated that SBS-EF accelerated burn wound healing in rats, increased hydroxyproline expression in skin tissue, facilitated skin structure repair, and enhanced collagen production and organisation over a 21 d period. Additionally, exposure to SBS-EF upregulated WNT3a and ß-catenin while downregulating GSK-3ß levels in rat skin tissue. CONCLUSIONS: The wound healing properties of SBS-EF were attributed to its ability to enhance HSF growth and migration, increase hydroxyproline levels in the skin, promote collagen accumulation, reduce scarring, and decrease the skin water content. SBS-EF may also provide therapeutic benefits for burns by modulating the Wnt/ß-catenin signalling pathway, as evidenced by its effective site and likely mechanism of action in the treatment of burned rats.
ABSTRACT
Background: The efficacy and safety of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) hydrogel in adults with deep partial-thickness burns have been confirmed. However, the clinical safety and efficacy analysis of rhGM-CSF in pediatrics is lacking, and the results are questionable. Therefore, a meta-analysis was conducted to evaluate the efficacy and safety of rhGM-CSF hydrogel in children with second- or third-degree burn injury to provide evidence-based medicine for clinical application. Methods: Articles on rhGM-CSF hydrogel for the treatment of pediatric burn wounds were retrieved from PubMed, Embase, WOS, Cochrane Central Registry of Controlled Trials, Chinese Biomedical Literature Database (CBM), China Science and Technology Journal Database (CSTJ), China National Knowledge Infrastructure (CNKI) and Wanfang from the inception of the databases to March 2024. Two reviewers screened articles and extracted the following data: general characteristics, intervention and treatment course, outcome measure. The meta-analysis was conducted using Revman 5.4 software. Results: Eight reports (336 patients: experimental 175, control 161) were ultimately included in the meta-analysis, which showed that the experimental group (rhGM-CSF hydrogel ± other therapy) was superior to the control group (treatments without rhGM-CSF hydrogel) in terms of the wound healing rates at day 7 [mean difference (MD) =13.63, 95% confidence interval (CI): 7.25 to 20.00, P<0.001], day 14 (MD =15.59, 95% CI: 12.50 to 18.69, P<0.001), and day 21 (MD =7.47, 95% CI: 7.36 to 7.58, P<0.001), and the wound healing time (MD =-3.10, 95% CI: -3.50 to -2.71, P<0.001), and the differences were statistically significant. For the risks of bias, one study had a "high risk" in allocation sequence concealment, and the others were classified as "low risk" and "unclear risk". Conclusions: rhGM-CSF hydrogel is significantly effective in improving the wound healing rate and shortening the wound healing time in children with second- or third-degree burns.
ABSTRACT
Severe burn injuries are defined by a prolonged hypermetabolic response characterized by increases in resting energy expenditure, systemic catabolism, and multi-organ dysfunction. The sustained elevation of catecholamines following a burn injury is thought to significantly contribute to this hypermetabolic response, leading to changes in adipose tissue such as increased lipolysis and the browning of subcutaneous white adipose tissue (WAT). Failure to mitigate these adverse changes within the adipose tissue has been shown to exacerbate the post-burn hypermetabolic response and lead to negative outcomes. Propranolol, a non-selective ß-blocker, has been clinically administered to improve outcomes of pediatric and adult burn patients, but there is inadequate knowledge of its effects on the distinct adipose tissue depots. In this study, we investigated the adipose depot-specific alterations that occur in response to burn injury. Moreover, we explored the therapeutic effects of ß-adrenoceptor blockade via the drug propranolol in attenuating these burn-induced pathophysiological changes within the different fat depots. Using a murine model of thermal injury, we show that burn injury induces endoplasmic reticulum (ER) stress in the epididymal (eWAT) but not in the inguinal (iWAT) WAT depot. Conversely, burn injury induces the activation of key lipolytic pathways in both eWAT and iWAT depots. Treatment of burn mice with propranolol effectively mitigated adverse burn-induced alterations in the adipose by alleviating ER stress in the eWAT and reducing lipolysis in both depots. Furthermore, propranolol treatment in post-burn mice attenuated UCP1-mediated subcutaneous WAT browning following injury. Overall, our findings suggest that propranolol serves as an effective therapeutic intervention to mitigate the adverse changes induced by burn injury, including ER stress, lipotoxicity, and WAT browning, in both adipose tissue depots. KEY MESSAGES: Burn injury adversely affects adipose tissue metabolism via distinct changes in both visceral and subcutaneous adipose depots. Propranolol, a non-selective ß-adrenergic blocker, attenuates many of the adverse adipose tissue changes mediated by burn injury.
ABSTRACT
Burn injuries in low-resource settings like Nepal present significant public health challenges, leading to substantial morbidity, mortality and severe pain. This paper assesses burn pain management in Nepal, emphasizing the need for enhanced strategies. A case study of a female patient with severe burn injuries from a rural village in Western Nepal illustrates current challenges. Reviewing studies on burn pain management in Nepal shows limited access to specialized facilities, inadequate palliative care, medication shortages and insufficient healthcare professionals. Pharmacological interventions are impacted by financial constraints and a lack of protocols, while nonpharmacological approaches have not been explored and contextualized for the Nepalese context due to similar financial issues. Comprehensive burn pain management requires addressing resource constraints through collaborative health-aid partnerships.
Burn injuries are among the most painful conditions. Burn injury treatment poses a significant challenge to low-resource countries like Nepal. This review focuses on the case of a 35-year-old woman from rural Nepal who suffered severe burns from boiling water. It depicts the journey and ordeal of the patient to receive burn pain treatment in Kathmandu, Nepal.Effective management of burn pain requires a multidisciplinary approach, including pharmacological and nonmedical treatments such as wound care and psychological support. However, in Nepal, these treatments are often limited due to resource shortages and a lack of specialized medical centers. The patient was eventually transferred to a burn injury treatment center in Kathmandu, Nepal, where multiple surgeries, including skin grafts donated by family members, helped her survive.The review also discusses various aspects of burn injuries in Nepal and the challenges of burn injury treatment and burn pain management in Nepal. It highlights the necessity for establishing specialized burn injury treatment centers and implementing a comprehensive burn injury management plan. These measures aim to enhance outcomes and alleviate suffering for burn patients in Nepal and other low-resource settings.
ABSTRACT
In modern burn care, the focus extends beyond mere patient survival to encompass long-term functional and cosmetic outcomes. Research suggests that the technique and manner of suturing during skin grafting play a significant role in scar formation. This study aimed to explore the effectiveness of wound edge approximation with skin grafting compared to the conventional approach, where the graft edge exclusively interacts with the wound edge, in reducing hypertrophic scar development. Seventy-four burn unit patients eligible for grafting were randomly allocated into two groups: those receiving grafts with overlapping edges (Group A) and those receiving grafts with edges tailored to the burn wound (Group B). Evaluation of graft sites occurred immediately post-surgery and at 1 and 6 months post-operatively using the standardized Vancouver Scar Scale (VSS) administered by trained surgeons. The findings of this study revealed that there was no statistically significant difference between the two examined groups regarding the average duration of hospitalization and the mean thickness of wounds (P>0.05). Similarly, the mean scores for pain, vascular index, and pigmentation index immediately post-surgery, at 1 month, and 6 months later, as well as the scar height index and flexibility immediately and at 1 month post-surgery, and the Vancouver Scar Scale index at the study's conclusion, showed no significant variation between the two groups (P>0.05). However, at the 6-month follow-up, the mean scar height score (P=0.004) in the overlapping group and the mean flexibility score (P=0.017) in the non-overlapping group were significantly lower compared to the respective alternative group. This indicates a notable improvement in scar height and wound flexibility in the overlapping group over the non-overlapping group after 6 months.
ABSTRACT
Acute kidney injury (AKI) is a common and severe complication in severe burns. Preexisting chronic kidney disease (CKD) can make the management more challenging. We present the management strategy adopted in such a case, highlighting the adaptations in fluid resuscitation, dialysis, and septicemia prevention. The case involved the 2nd and 3rd degree burns covering 53% body surface, in a patient with preexisting CKD and hypertension. Despite initial fluid resuscitation, the patient developed AKI. Sustained low-efficiency dialysis (SLED) was started, along with nutritional support using buttermilk diet. Aggressive antibiotic prophylaxis was initiated based on wound swabs culture and sensitivity. Wound debridement was deferred and daily dressing with silver nitrate gel and moisture-retaining film was used. Debridement and grafting were performed on postburn days 43 and 65. The patient was discharged after 80 days, with healed wounds. Our approach included meticulous fluid and nutrition supplementation coupled with SLED and appropriate wound management coupled with aggressive antimicrobial prophylaxis to prevent septicemia.
ABSTRACT
Background and Aims: Burn and scald injuries are the fourth most common type of trauma. Pediatric burns account for a high proportion of the total number of burn patients and impose a high burden on public health. Understanding the epidemiology of pediatric burns can help improve science education and reduce the incidence of burn injuries. Methods: This study is a single-center retrospective study. One thousand five hundred and twenty-seven pediatric burn patients admitted to our burn center from January 2016 to December 2020 were included. Demographic and epidemiological data of included patients were extracted and analyzed. The correlations of categorical data were tested by the Chi-square tests, and differences of continuous data were tested by the Kruskal-Wallis tests. A p-value of less than 0.05 was considered to be statistically significant. Results: The results showed that children under 3 years of age were most susceptible to burn and scald injuries. Burn injuries were most likely to occur in the season of winter and at the place of home. 56.6% of included patients did receive first aid measures, while 1.8% received gold-standard first aid. Clinical variables related to the severity of injuries were statistically different between patients with and without cooling measures in first aid. Linear regression models showed that emergency treatment of burns in children and adolescents was associated with outcome indicators, including number of operations, total operation duration per total burn surface area (TBSA), cost per TBSA, and length of stay per TBSA. Conclusions: This study summarized the epidemiology and outcomes of pediatric burn patients admitted to a burn center in northern China. Adopting cooling measures in first aid can reduce the severity of injuries and reduce the burden on the medical system. Education on burn prevention and first aid measures to caregivers of children, especially preschool children, should be strengthened.
ABSTRACT
Pseudomonas aeruginosa is one of the main causes of healthcare-associated infection in Europe that increases patient morbidity and mortality. Multi-resistant pathogens are a major public health issue in burn centers. Mortality increases when the initial antibiotic treatment is inappropriate, especially if the patient is infected with P. aeruginosa strains that are resistant to many antibiotics. Phage therapy is an emerging option to treat severe P. aeruginosa infections. It involves using natural viruses called bacteriophages, which have the ability to infect, replicate, and, theoretically, destroy the P. aeruginosa population in an infected patient. We report here the case of a severely burned patient who experienced relapsing ventilator-associated pneumonia associated with skin graft infection and bacteremia due to extensively drug-resistant P. aeruginosa. The patient was successfully treated with personalized nebulized and intravenous phage therapy in combination with immunostimulation (interferon-γ) and last-resort antimicrobial therapy (imipenem-relebactam).

Burns generate every year an important burden of morbidity, being a major global public health problem through prolonged hospitalization, complications, and increased mortality. This study's purpose was to evaluate the serum levels of three adipokines and to establish significant correlations with other circulating molecules and with some clinical parameters. We evaluated 32 children with severe burns (over 25% total burned surface area-TBSA) at 48 h, day 10, and day 21 post burn, and 21 controls. The serum levels of adiponectin, resistin, leptin, tumor necrosis factor-α (TNF-α), plasminogen activator inhibitor-1 (PAI-1), and C-reactive protein (CRP) (among nine other biochemical parameters) were detected by Multiplex technique. Significant statistical differences were obtained for resistin and leptin compared to the control group, in different moments of measurements. Adiponectin serum levels presented statistically significant correlations with hot liquid mechanism of burn, the Revised Baux score, TBSA, resistin, PAI-1, CRP, TNF-α, and triglycerides (TGLs) serum levels. Resistin serum levels presented statistically significant correlations with adiponectin, CRP, PAI-1, leptin, and TNF-α. Additionally, we found statistically significant correlations between leptin serum levels and length of hospitalization, TNF-α, resistin, adiponectin, and PAI-1 serum levels. In severely burned children, adiponectin, resistin, and leptin specifically correlate with clinical parameters and with proteins involved in the systemic inflammatory response and the hypermetabolic response.

BACKGROUND: The impact of inhalation injury on risk of nosocomial pneumonia (NP), an important complication in patients with burns, is not well established. RESEARCH QUESTION: Is more severe inhalation injury associated with increased risk of NP? STUDY DESIGN AND METHODS: We performed a retrospective cohort study of patients with suspected inhalation injury admitted to a regional burn center from 2011 to 2022 who underwent diagnostic bronchoscopy within 48 h of admission. We estimated the association of high-grade inhalation injury (Abbreviated Injury Scale score 3 and 4) vs low-grade inhalation injury (Abbreviated Injury Scale score 1 and 2) with NP adjusted for age, burn size, and comorbid obstructive lung disease. Death and hospital discharge were considered competing risks. RESULTS: Of the 245 patients analyzed, 51 (21%) had high-grade injury, 180 (73%) had low-grade injury, and 14 (6%) had no inhalation injury. Among the 236 patients hospitalized for ≥ 48 h, NP occurred in 24 of 50 patients (48%) in the high-grade group, 54 of 172 patients (31%) in the low-grade group, and two of 14 patients (14%) in the no inhalation injury group. High-grade (vs low-grade) inhalation injury was associated with higher hazard of NP in both the proportional cause-specific hazard model (cause-specific hazard ratio, 2.04; 95% CI, 1.26-3.30; P = .004) and Fine-Gray subdistribution hazard model (subdistribution hazard ratio for NP, 2.24; 95% CI, 1.38-3.64; P = .001). INTERPRETATION: Among patients with inhalation injury, more severe injury was associated with higher hazard of NP in competing risk analysis. Additional research is needed to investigate mechanisms that may explain the relationship between inhalation injury and NP and to identify more effective risk reduction strategies.
ABSTRACT
Violence against women is a global public health problem. CDC data shows 41% of US women have experienced intimate partner violence. Burn-related violence against women is an extremely confronting form of physical violence. The aim of this study was to describe the frequency, demographics, injury characteristics and outcomes of women admitted to US burn centers who have experienced burn violence compared to those with accidental burn injuries. 2008-2018 data was queried from the ABA Burn Quality Care Platform registry for patients that were women and ≥18 years old. Women who experienced an assault or accidental burn injury were included. Women who experienced self-harm were excluded. Descriptive/simple comparative statistics were used to describe/compare groups. 54,523 women met study inclusion criteria. 956 (2%) experienced burn violence. Women who experienced burn violence had a younger median [IQR] age (36 [27,48] vs 47 [32,61],p<0.0001), were Black/African American (44.5% vs. 22.4%,p< 0.0001), were covered by Medicaid (38.8% vs. 21.6%,p< 0.0001), had a higher median [IQR] %TBSA extent (6.0% [3,15.2] vs. 3.0% [1,7.3],p< 0.0001), a higher proportion with 3rd degree burns (35.4% vs. 28.9%,p<0.0001), and a higher proportion with TBSA >20% (18.2% vs. 6.7%,p<0.0001). Scald/flame injuries were the most frequent mechanism of injury. Women who experienced violence had a higher median [IQR] length of hospital stay (7.0 [2,18] vs. 4.0 [1,11] days, p< 0.0001), ICU stay (8.5 [2,27] vs. 4 [2,13] days,p< 0.0001), and mortality rate (5.7% vs 4.3%,p<0.04). The frequency of women who sustained burn violence appears small yet experience worse outcomes. Clinicians should be aware of these demographic/clinical characteristics to provide optimal care to this vulnerable population.
