Landmarks in burn prevention

As time goes by - Overlooking 40 years of inpatient burn treatment at a national pediatric burn center in Switzerland

BACKGROUND

Despite extensive prevention programs, burns remain a frequent cause of injury in Switzerland with a known age peak in children. Pediatric burns may cause substantial morbidity, a psyochological burden and therapy related high economic costs. To improve preventive measures, precise knowledge of etiology and treatment of pediatric burns in Switzerland as well as their temporal evolution is indispensable.

METHODS

The present retrospective analysis included pediatric burn patients admitted for acute treatment to the Pediatric Burn Center of the University Children`s Hospital Zurich over the last four decades. Sociodemographic, injury related, and treatment related data were extracted from medical records. Linear regression analysis was applied to determine temporal changes during the past four decades and chi-square and t-tests were applied wherever applicable.

RESULTS

A total of 3425 acute burn patients were included in the study between 1977 and 2020, corresponding to a mean of 89 patients/year. Mean age was 3.60 ± 4.12 years, three quarters of all patients were preschool children (0-5 years) and mean total body surface area (TBSA) burned was 8.01% ± 9.57%, however only around one fifth had severe burns (>10% TBSA). Scald burns (65.31%) and flame burns (32.99%) were most commonly seen. Linear regression analysis showed the total number of thermal injuries treated at our center to have increased significantly as of 2004 (p < 0.001). Separate analysis showed the same for small and medium (<10% TBSA) burns (p < 0.001), whereas the number of severe burns did not increase significantly. Length of stay (LOS) was highly associated with %TBSA burned. The percentage of female patients amongst all patients increased over time (p = 0.012). LOS per TBSA burned decreased significantly (p < 0.001).

CONCLUSION

The present data show pediatric burns to remain a major health burden in Switzerland, especially small and medium burns in preschool children. Prevention programs should focus on this age population as well as on scald and flame burns as most common etiologies. The observed decrease in length of stay suggests a major improvement in overall quality of care in pediatric burns and supports centralization of care.

Skin Bank Establishment in Treatment of Severe Burn Injuries: Overview and Experience with Skin Allografts at the Vienna Burn Center

Depending on their extent, burn injuries require different treatment strategies. In cases of severe large-area trauma, the availability of vital skin for autografting is limited. Donor skin allografts are a well-established but rarely standardized option for temporary wound coverage. Ten patients were eligible for inclusion in this retrospective study. Overall, 202 donor skin grafts obtained from the in-house skin bank were applied in the Department of Plastic and Reconstructive and Aesthetic Surgery, Medical University of Vienna. Between 2017 and 2022, we analysed the results in patient treatment, the selection of skin donors, tissue procurement, tissue processing and storage of allografts, as well as the condition and morphology of the allografts before application. The average Abbreviated Burn Severity Index (ABSI) was 8.5 (range, 5-12), and the mean affected total body surface area (TBSA) was 46.1% (range, 20-80%). In total, allograft application was performed 14 times. In two cases, a total of eight allografts were removed due to local infection, accounting for 3.96% of skin grafts. Six patients survived the acute phase of treatment. Scanning electron microscope images and histology showed no signs of scaffold decomposition and intact tissue layers of the allografts. The skin banking program and the application of skin allografts at the Vienna Burn Center can be considered successful. In severe burn injuries, skin allografts provide time by serving as sufficient wound coverage after early necrosectomy. Having an in-house skin banking program at a dedicated burn centre is particularly advantageous since issues of availability and distribution can be minimized. Skin allografts provide a reliable treatment option in patients with extensive burn injuries.

Economic Burden of Denatured Alcohol-Induced Burns: A 20-Year Retrospective Study

Burn care has rapidly improved over the past decades, but health innovations are expensive. We present the first study focusing on the economic burden of exclusive denatured alcohol-induced burns. The goal of this study was to determine costs for the public health system due to inpatients’ burn care because of these specific burns. Moreover, we aimed to observe the incidence of methylated spirit-related burns in the past 20 years. We performed an observational retrospective study in our burn unit including all patients with a denatured alcohol-related burn injury from 1 January 2001 to 31 December 2020. A total of 503 patients with a mean burn size of 24% were hospitalized; the mean annual total costs per patient was €43,879, varying from €31,518 to €63,274.00€; the total costs for denatured alcohol-related burns during the period 2001–2020 was €21,145,076. We noted an increasing incidence of denatured alcohol-related burns and related costs over the years, especially in the last decade. Our results highlight that burns by methylated spirits are still a real and expanding problem. Therefore, authorities should focus on sales rules, characteristics of the containers, and education of people who misuse denatured alcohol, based on historical habits of use. To reduce the socioeconomic costs of burns, future intervention strategies and studies from the dermatology community and burn specialists should focus on prevention programs and prompt wound healing to shorten the length of hospital stay, enable quick return to work, and improve the outcomes of patients with burns.

Expert consensus on the prevention and first-aid management of burns in children

Burns are the second leading cause of unintentional injuries in children and are one of the major causes of disability in children. Timely and effective first-aid management of burns can have a major impact on the prognosis, but there is still a lack of the knowledge on burn management in the general public. With reference to expert opinions and related literature, this consensus summarizes the causes of burns, preventive measures, first-aid methods for common types of burns, and the prevention and treatment of serious complications of burns. It also provides recommendations on the most appropriate pre-hospital treatment. This consensus aims to emphasize the importance of burn prevention, improve the ability of first-aid treatment among witnesses and rescuers, avoid further injury caused by inappropriate treatment, and reduce the mortality and disability rates of burns and the harm to family and society. It can be used as guidance for pre-hospital treatment of childhood burns by first responders, parents, and passers-by.

Prevention of unintentional injuries in children under five years

We looked at existing recommendations for preventing unintentional injuries in children under five years of age, and we attempted to identify the main sources used as evidence for formulating these recommendations.

We conducted a literature search up to the 18th October 2019 by using key terms and manual search in selected sources. We summarized the recommendations and source of the evidence in tables for each of five areas of unintentional injuries: road traffic injuries, drowning, poisoning, thermal injuries, falls.

In 2008, the World Health Organization (WHO) published a comprehensive report with strategies for child injury prevention for the European region. More recently, the WHO published several guidance documents focused on one area such as drowning, usually with a global focus. The PrevInfad workgroup (Spanish Association of Primary Care Pediatrics) updated their document on road safety in April 2019, providing recommendations and a summary of the existing evidence. Preventive strategies for injuries in childhood are mainly based on surveillance data and the identification of risk factors. The key strategies for preventing unintentional injuries are a combination of environmental and behaviour modification, that can be achieved through engineering, enforcement and education. Consequently, for this kind of strategies, it is important to evaluate the effectiveness of both the intervention itself, and the way the intervention is advised to parents and caretakers so that there is good compliance of the recommendation.

The Descriptive Epidemiology and Outcomes of Hospitalized Burn Patients in Southern Turkey: Age-Specific Mortality Patterns

The current descriptive analysis was designed to document the common epidemiologic characteristics and outcomes of burn injuries, and age-specific mortality patterns covering all age groups admitted for treatment to the Burn Center of Adana City Training and Research Hospital. Medical records were retrospectively analyzed. The patients were stratified into two age groups as pediatric and adults, and then into 10 sub-age groups. Among the 946 patients of the study population, there were 24 mortalities with a mortality rate of 2.5%. Patients within the age range of 70 to 79 years had the highest mortality rate of 33.3%; followed by 60 to 69, 80+, 18 to 29, 10 to 17, and <5 sub-age groups, whose mortality rates were 13.0%, 7.8%, 7.2%, 2.4%, and 0.5%, respectively. In terms of multivariate regression analysis of factors predicting mortality among burn patients in all age groups, fire-flame related burns, age ≥18 years, TBSA burned ≥20% (TBSA ≥20%), the existence of inhalation injury, deep partially/full-thickness burns were found to be significant prognostic factors of mortality. The strongest association was seen in TBSA ≥60% segment (P < .0001), which had 25.9 times more death risk. As expected, a similar trend was detected when the age groups stratified into age groups, and the strongest association was in the 60+ sub-age group (P < .0001), whose had 5.84 times more likely death; followed by 29 to 59 and 18 to 29 sub-age groups, with the odds ratios of 2.12 (95% confidence interval = 1.25-3.61) and 2.08 (95% confidence interval = 1.90-4.05), respectively. Oppose to these findings; the 0 to 17 sub-age group was not found to have a statistically significant effect in predicting mortality.

Biomimetic algal polysaccharide coated 3D nanofibrous scaffolds promote skin extracellular matrix formation

Development of functional biological substitutes for skin tissue engineering applications has observed several advancements over the past few decades. In this regard, intelligent extracellular matrix (ECM) mimetic scaffolds have recently evolved as a promising paradigm by presenting instructive cues directing cell-matrix communication, tissue remodeling and homeostasis. However, orchestring multitude attributes of skin ECM yet presents an intriguing challenge to be addressed. In the present work, we have developed an in vitro skin scaffold by coating a bio-mimetic ECM cue κ-carrageenan on electrospun nanofibers for the first time. κ-Carrageenan, a natural sulfated algal polysaccharide exhibits close similarity with native glucosaminoglycans (GAGs) of skin ECM. On the other hand, electrospun nanofibers resemble the 3D nano-topographic architecture of ECM. In the coated form, κ-carrageenan could provide the biochemical cues necessary for cellular functions on the nanofibrous scaffold, thereby mimicking the native 3D microenvironment of skin ECM. The nano-architecture of the electrospun matrix is retained in the fabricated scaffold even after coating with κ-carrageenan. The developed biomimetic scaffold significantly supplements adhesion, growth, infiltration, survival and proliferation of fibroblasts. Furthermore, enhanced gene expression and excessive secretion of collagen proteins by fibroblasts communicate a conducive skin ECM micro-environment formation on the algal polysaccharide coated nanofibrous scaffold. Taken together, these findings present a simple yet effective strategy for the fabrication of ECM mimetic scaffold for promising skin tissue engineering applications.

Trends in burn injury mortality in Spain (1979-2018): Sex-specific age-cohort-period effects

BACKGROUND

Previous studies about burns mortality are often exclusively based on hospital and burn centre data. National population-based reports on this topic are rather limited. The aim of this study was to analyse sex- and age-specific mortality rates of burns in Spain during the period 1979-2018.

METHODS

Age-standardised burns mortality rates were calculated from death records and mid-year population data were provided by the Spanish National Statistics Institute. Joinpoint regression analyses were used to identify significant points of change in trends over time and to compute average annual per cent change (AAPC). Age, period and cohort effects were also analysed.

RESULTS

Mortality due to burn injury decreased in both sexes between 1979 and 2018: from the first quinquennium of this period up to the last one age-adjusted mortality rates decreased from 1.37 to 0.49 per 100,000 in men and from 0.96 to 0.26 per 100,000 in women.

CONCLUSIONS

Burns mortality rates in Spain have been decreasing during the last decades. Promotion of primary prevention measures should continue.

Hospital-Based Emergency Department Visits With Pediatric Burns: Characteristics and Outcomes

OBJECTIVE

The objective of this study was to examine the characteristics and outcomes in children presenting to emergency departments (EDs) with burn injuries.

METHODS

The Nationwide Emergency Department Sample (NEDS) for the years 2008 to 2013 was used. All patients younger than 18 years who visited a hospital-based ED with a burn injury were selected. The study focused on (1) demographics (age, sex, insurance status), (2) characteristics of burns (types, causes), (3) disposition status after ED/hospitalization, (4) charges (ED and hospital), and (5) patient outcomes. Inclusion criteria were a visit to ED in the United States with a burn. Descriptive statistics were used to summarize the findings.

RESULTS

During the study period, there were 746,593 ED visits due to burn injuries. Majority were insured by Medicaid (52.8%). Most frequent injuries were burns of wrists/hands (39.5%), lower limbs (24.1%), and upper limb-except wrist/hand (20.1%). The most common causes of burns were heat from electric appliances (37.1%) or hot liquids and vapors (24.8%). Following the ED visit, 89.1% were discharged routinely, and 4.3% were admitted. Mean charge per patient per ED visit was $1117. Total ED charges across the United States was $708.7 million. When admitted, mean length of stay was 5.7 days. Total hospitalization charge across the United States was $1.7 billion.

CONCLUSIONS

Pediatric burn injuries require significant resources for stabilization and treatment by EDs. The present study highlights the burden and impact of pediatric burn injuries in the United States.

Trends of Burn Injury in the United States: 1990 to 2016

OBJECTIVE

The aim of this study is to report patterns of burn injury within the United States from 1990 to 2016 with regard to age, sex, geography, and year.

SUMMARY BACKGROUND DATA

Advances in the management of burn injuries as well as successful public health efforts have contributed to reductions in the annual incidence and mortality of burns. However, several studies suggest that these reductions are not equally distributed throughout the US population.

MAIN OUTCOMES AND MEASURES

The Global Burden of Disease Study 2016 was utilized to collect incidence, mortality, disability-adjusted life years (DALYs), and years lived with disability (YLD) from 1990 to 2016. All measures were computed with 95% uncertainty intervals (UI).

RESULTS

The overall incidence of burn injury in the United States has decreased from 215 (95% UI, 183-246) to 140 (95% UI, 117-161) per 100,000. However, the relative mortality of burn injury has been fixed over the 26-year study period. Alaska had the highest rates of burn incidence in 1990 and 2016, closely followed by southeastern states. When adjusted for incidence, relative mortality in 1990 was highest in Alabama and Mississippi and the mortality-incidence ratio increased for these states in 2016. In addition, 35 states also demonstrated an increase in the relative mortality of burn injury during the study period.

CONCLUSIONS

Regional trends of burn incidence and mortality are highly variable and are likely due to a multitude of factors. Addressing these disparities will require close examination of the contributing factors of burn injury and severity.

The Relationship Between Income and Burn Incidence in Winnipeg, Manitoba, Canada: A Population Health Study

Burns continue to be a common cause of morbidity around the world, and socioeconomic status has been linked to high-burn risk in developed and developing countries. The purpose of this study was to define in Winnipeg, Manitoba, Canada: 1) demographics of adult patients with severe burns; 2) the relationship between household income and burn incidence; and 3) specific geographic areas that may benefit from targeted burn prevention strategies. We conducted a retrospective study of adult (>18 years) patients in Winnipeg, with burns severe enough to require at least 1 day of hospitalization between 2006 and 2016. Area-level median household income data at two geographic levels were collected from 2011 Census based on patient postal codes. Of 207 patients that met study criteria, 156 (75.4%) were male. Mean age was 44.5 ± 16.9 years, and the most common cause of burns was fire/flame (52.2%). The analysis of income data revealed that lower area-level income groups had a higher incidence of burns, with the lowest income quintile group having 5.4 times higher incidence than highest income quintile group. Spatial analysis software was used to map the incidence rates, and clusters of high-risk burns were identified in and around the city center region. Overall, our study showed an inverse relationship between area-level income and burn injury incidence. The identification and mapping of high incidence hotspots will allow policy makers to target groups who will benefit most from burn prevention strategies.

Fireworks and Seafood Boils: The Epidemiology of Burns in Louisiana

Epidemiological trends provide a means for targeting efforts in burn prevention. There have been but few regional-specific studies concerning burns in the southern United States. This study describes burn injury trends experienced by a single burn center in Louisiana. We also investigate the temporal relationships of several activities informally known for having a high risk for burn injury among local providers. Data were retrospectively extracted from the records of all patients treated for burn injuries at the regional burn center from 2012 to 2018 in both inpatient and outpatient settings. Demographical data and burn injury characteristics were noted. A total of 6,498 patients were included (1,593 inpatient, 4,905 outpatient). The most common burn etiologies were scald and flame, with flame being associated with more severe injuries. Overall incidence was disproportionally high in males and children less than 4 years of age. Total incidence was highest in Caucasians, though African Americans held the highest annual incidence rate specific to this population. The most common situation at the time of burn injury involved the consumption or preparation of food or beverages. Significant variation was observed in the rates of different injury situations throughout the year. Notably, burns related to seafood, heating, and firework activity occurred more often during crawfish season, colder months, and the months of January and July, respectively. In addition to establishing preliminary trends, these data may be useful in guiding the development of future evidence-based prevention efforts to target the most detrimental burn injuries in this population.

Absence of Therapeutic Benefit of the Anti-Inflammatory Protein TSG-6 for Corneal Alkali Injury in a Rat Model

Purpose: To investigate the therapeutic efficacy of tumor necrosis factor (TNF)-α stimulated gene/protein 6 (TSG-6) in a rat model of corneal alkali injury. Methods: Corneal alkali injury was produced by placing an NaOH-soaked filter paper disk on the central cornea of the right eye of an anesthetized male Lewis (LEW/Crl) rat. Recombinant human TSG-6, or an equal volume of phosphate-buffered saline (PBS), was administered intravenously (IV), by anterior chamber (AC) injection, or as a topical drop. The affected eyes were photographed daily using a dissecting microscope and documented for clinical time course analysis of corneal opacification. Corneal tissue was excised at pre-determined therapeutic endpoints, with subsequent qRT-PCR or histological analyses. Results: The continuous monitoring of corneal alkali injury progression revealed TSG-6 treatments do not show sufficient effectiveness in vivo regardless of IV injection, AC injection, or topical application. Corneal opacification and neovascularization were not diminished, and gene expression was not impacted by these treatments. However, both IV and AC administration of TSG-6 significantly suppressed pro-inflammatory cytokines compared to PBS-treated eyes. Conclusion: We conclude that the therapeutic potential of TSG-6 is insufficient in a rat corneal alkali injury model.

Epidemiological study of burn patients hospitalised at a burns centre, Manipal

Burn injuries constitute a major public health problem and account for a significant cause of mortality and morbidity amongst the Indian population. This 2-year prospective study was undertaken to find out the exact epidemiological determinants of 737 patients admitted with burn injuries and, thus, to try and formulate effective preventive strategies. This study was conducted in the department of plastic surgery and burns from September 2011 to June 2013. All consecutive patients with major burns admitted for in-hospital treatment during the study period were included in the study. The data collected included age, gender, cause and mode of burns, total burn surface area (TBSA), microbiological profile and outcome. More than 55% of the patients were female (58.61%). The mean age was 31.3 years ranging from 8 months to 89 years. A higher number of females (97.5%) sustained burn injuries at home compared with 36.11% males sustaining injuries outdoors. (P = 0.000). Almost one third of injuries (40.36%) occurred between 4 pm and 8 pm, followed by 28% between 7 am and 12 noon. Synthetic garments were worn by 70% of females at the time of injury, whereas 40% of males had worn mixed clothing (P = 0.000). Flame injuries contributed to 80.1% of burns in females (P = 0.006). The rate of electrical injuries (9.8%) was significantly higher in males (P = 0.005). In almost 40% of males, TBSA was <19%, whereas in 40% of females, TBSA was >68%. (P = 0.004). Microbial profile showed that pseudomonas aeruginosa (n = 260; 35.3%), Klebsiella pneumoniae (n = 209; 28.5%), and Escherichia coli (n = 145; 22.6%) were the most frequent types of Staphylococci bacterial growths. The cause for burn injury was ignition of clothes in 68.74% females, and in 35.48% males, it was because of an attempt to save other burn injury victims (P = 0.013) The case fatality rate was 29.3%. A majority of the males (60.7%) recovered, whereas 45.89% of females succumbed because of their burn injury. (P = 0.001). As the aetiological factors of burn injuries vary considerably in different communities, careful study of the pattern in every community is needed before a sound prevention programme can be planned and implemented. Hence, this study was conducted to assess epidemiological, modes, causes, and risk factors and the microbial profile of burn injuries and to study the outcomes.

Acute chemical skin injuries in the United States: a review

The objective was to perform a thorough review of published and other available data to elucidate the extent of chemical skin injuries in the US. Chemical skin injuries differ significantly from skin lesions produced by other injury mechanisms, so this review was restricted to the former. Retrieval of relevant published data was performed in PubMed and Google. Other data were retrieved from the American College of Surgeons National Trauma Databank, American Burn Association National Burn Repository, US Department of Labor Bureau of Labor Statistics, websites of all 50 US States Departments of Health, and the National Poison Data System of the American Association of Poison Control Centers. Two areas of significance in disfiguring skin burn injuries and particularly of chemical skin injuries, psychosocial issues and the associated financial burden, have been briefly reviewed. Because of the paucity of published data, international as well as US data have been included. A brief description of an active flushing fluid as an alternative to potable water, Diphoterine^® solution, has also been included. Chemical skin injuries generally comprise approximately 2-5% of all skin burns, but sometimes higher percentages have been reported. Data analysis shows that while there are various sources regarding the epidemiology of chemical skin injuries, the total annual number cannot be determined because there is no centralized US national reporting mechanism. Literature and clinical experience demonstrate the importance of chemical skin injuries in USA. Dermal exposures to chemicals can result in mortality and morbidity. Chemical skin injuries can be avoided or ameliorated and preventive advanced measures should be taken to reduce or ameliorate them.

Risk factors for burn injuries and fire safety awareness among patients hospitalized at a public hospital in Nairobi, Kenya: A case control study

INTRODUCTION

Burn injuries are some of the most physically and psychologically devastating forms of trauma and most common injuries affecting children, especially in the home environment. They are more prevalent and are a public health problem in developing countries mainly because of poor socio-economic conditions. Effective prevention programs should be guided by the results of well-designed studies aimed at investigating risk factors for burns.

STUDY OBJECTIVE

To establish the risk factors for burn injuries among patients hospitalized at the Kenyatta National Hospital (KNH).

METHODOLOGY

This was an age and gender matched case-control study comprising 202 patients admitted with burns (cases) and 202 non-surgical patients (controls) admitted into the pediatric and medical wards. The study site was KNH, a 1800-bed national referral and teaching hospital in Kenya.

DATA ANALYTICAL METHODS

SPSS version 17 was used for data analysis, with descriptive statistics used for demographic data, whereas in the analysis for risk factors chi square test and odds ratio (OR) were used to determine the relationship between the predictive (risk factors) and outcome variables (burn injury). Logistic regression was used to determine the strength of association between risk factors and burn injury.

RESULTS

The risk factors found to be significant for burn injuries were: low level of education (p=0.043), use of kerosene as fuel for cooking (OR=2.027; 95% CI: 1.361-3.019, p=0.000) and lack of knowledge of burn injury prevention and fire safety (OR=4.009; CI: 2.603-6.172, p=0.000).

CONCLUSION

Low level of education, use of kerosene for cooking and lack of knowledge of burn injury prevention and fire safety were identified as risk factors for burn injury among patients hospitalized at KNH. These risk factors should be addressed in burn injury prevention programs for Kenya.

A Case Series of Candle Wax Burns during the Lantern Festival in Hong Kong

Every year there was significant number of burn cases during the Lantern (Mid-Autumn) Festival in Hong Kong because children liked to play with fire on that day. They would either burn the lantern or boil the wax from candles in a pot over a fire. When the wax has melted, they poured cold water into it, causing a small explosion with water vapour and wax droplets. Children and adolescents were more common than adults to be burnt by the hot vapour, fire or hot wax. The majority sustained partial thickness burns involving the face. Such burn injuries should be preventable by education and legislation.

Risk of hospitalization for fire-related burns during extreme cold weather

BACKGROUND

Environmental factors are important predictors of fires, but no study has examined the association between outdoor temperature and fire-related burn injuries. We sought to investigate the relationship between extremely cold outdoor temperatures and the risk of hospitalization for fire-related burns.

MATERIAL AND METHODS

We carried out a time-stratified case-crossover study of 2470 patients hospitalized for fire-related burn injuries during cold months between 1989 and 2014 in Quebec, Canada. The main exposure was the minimum outdoor temperature on the day of and the day before the burn. We computed odds ratios (OR) and 95% confidence intervals (CI) to evaluate the relationship between minimum temperature and fire-related burns, and assessed how associations varied across sex and age.

RESULTS

Exposure to extreme cold temperature was associated with a significantly higher risk of hospitalization for fire-related burns. Compared with 0°C, exposure to a minimum temperature of -30°C was associated with an OR of 1.51 (95% CI 1.22-1.87) for hospitalization for fire-related burns. The associations were somewhat stronger for women, youth, and the elderly. Compared with 0°C, a minimum temperature of -30°C was associated with an OR for fire-related burn hospitalization of 1.65 for women (95% CI 1.13-2.40), 1.60 for age < 25 years (95% CI 1.02-2.52), and 1.73 for age ≥ 65 years (95% CI 1.08-2.77).

DISCUSSION

Extremely cold outdoor temperature is a risk factor for fire-related burns. Measures to prevent fires should be implemented prior to the winter season, and enhanced during extreme cold.

Injuries due to fireworks use: A surveillance data analysis in Colombia, 2008-2013

PURPOSE

To describe the injuries due to fireworks use in Colombia during the period 2008-2013 and to identify factors associated with hospitalization and death due to this cause.

METHODS

A descriptive study from surveillance data was carried out. Incidence rates and relative risks were calculated. The incidence rate trend was modeled with a joint point regression model. Multivariate logistical models were implemented to identify the associated factors with hospitalization and mortality due to firework injuries.

RESULTS

A total of 6585 people were reported to be injured by fireworks during the 2008-2013 period. An upward trend in the incidence rate during this period was observed, with an annual percentage of change of 28% (95% CI 27.7-28.3) during 2008-2011 and 3.5% (95% CI 3.0-3.9) during 2011-2013. The factors associated with hospitalization were injury occurrence at the workplace (odds ratio (OR) 2.62, 95% CI 1.97-3.47), storage (OR 2.40, 95% CI 1.54-3.73), transport (OR 1.63, 95% CI 1.20-2.21), multiple trauma (OR 1.49, 95% CI 1.31-1.70), and injury occurrence at home (OR 1.26, 95% CI 1.07-1.50). The factors associated with mortality were storage (OR 19.52, 95% CI 4.62-82.44), transport (OR 13.37, 95% CI 3.29-54.3), injury occurrence at the workplace (OR 4.88, 95% CI 1.69-14.13), and ethnicity (OR 3.37, 95% CI 1.12-10.12).

CONCLUSION

These results provided information for revising the public policies and intersectorial interventions to reduce the avoidable burden due to firework injuries at all times and not just during the high injury occurrence season.

Baby walker injury, disability, and death in a high-income middle eastern country, as reported by siblings

Background

Baby walkers (BWs) are frequent causes of infant injuries. Little research is reported from the Middle East and few population-based studies anywhere.

Methods

Using multistage random sampling in a city of the United Arab Emirates, 4 of 8 female Arab government high schools and 3 final-year classes each from science and arts tracks were selected. Structured self-administered questionnaires assessed prevalence, frequency, severity, and external causes of BW incidents and injuries, and residential hazards.

Results

Response was 100 %, 696 students, 55 % (n = 385) Emirati citizens. 87 % (n = 605) of families used/had used BWs. Among 646 injuries were 118 ER (emergency) visits, 42 hospitalizations, 11 disabilities, and 3 deaths. Average risk was 1 incident/user, 1 injury/4 users, 1 ER visit/20, 1 hospitalization/55, 1 disability/200, 1 death/1000. Odds ratios for >1:1 floor levels were 2.3 (95 % confidence interval: 1.2, 4.3) for hospitalization, 16.8 (95 % CI: 2.1, 132.5) disability. Incidents included hitting objects 48 % (n = 1322), overturning 23 % (n = 632), accessing hazardous objects 17 % (n = 473), and falling down stairs 11 % (n = 300); 1 % (n = 32) fell into swimming pools. In 49 % (n = 297/605) of user families, ≥1 child had been injured.

Conclusions

Despite causing many injuries including disabilities and fatalities, BWs were used by nearly all families. Governments should consider Canada’s lead in prohibiting importation, sales, and advertising of BWs.

Epidemiology of burns and scalds in children presenting to the emergency department of a regional burns unit: a 7-year retrospective study

BACKGROUND

Variation in the incidence and mechanism of thermal injury has been reported in different age groups in children. The aim of this study was to report the incidence, mechanisms, and environmental factors of all burns presentations to the emergency department (ED) of a regional burns centre over a 7-year period.

METHODS

A retrospective, chart review study of all burns presentations to the ED of a regional burns centre in South Wales was conducted. All children recorded as having sustained a burn or scald, aged less than 16 years were included in the analysis. Subjects' demographics were analysed using descriptive statistics, and comparisons were made between patients aged less than 5 and patients aged 5-16 using chi-square test and Mann-Whitney U test.

RESULTS

A total of 1387 cases were included in the final analysis. Scalds were the most common thermal injury with 569 (41.0 %) reported, followed by contact burns in 563 (40.6 %) patients. The patients requiring hospitalisation were significantly younger (2 vs 3 years; p < 0.001) and had a higher rate of non-accidental injury (10 vs 4; p < 0.001). The most commonly injured site in both age groups was a hand or digit.

CONCLUSIONS

Scalds and contact burns were the most commonly reported thermal injury in children aged less than 16. Common mechanisms were hot beverages, hobs and hair straighteners, highlighting further burn prevention strategies are needed and good-quality prospective studies that investigate the effectiveness of such strategies.

Individual-level predictors of inpatient childhood burn injuries: a case-control study

Background

Burn injuries are considered one of the most preventable public health issue among children; however, are a cause of significant morbidity and mortality in Iran. The aim of this study was to assess individual-level predictors of severe burn injuries among children leading to hospitalization, in East Azerbaijan Province, in North-West of Iran.

Methods

The study was conducted through a hospital based case–control design involving 281 burn victims and 273 hospital-based controls who were frequency matched on age, gender and urbanity. Both bivariate and multivariate methods were used to analyze the data.

Results

Mean age of the participants was 40.5 months (95 % CI: 37–44) with the majority of burns occurring at ages between 2 months-13.9 years. It was demonstrated that with increase in the caregiver’s age there was a decrease in the odds of burn injuries (OR = 0.94, 95 % CI: 0.92-0.97). According to the multivariate logistic regression there were independent factors associated with burn injuries including childhood ADHD (OR = 2.82, 95 % CI: 1.68 - 4.76), child’s age (OR = 0.73, 95%CI: 0.67 - 0.80), flammability of clothing (OR = 1.60, 95 % CI: 1.12 - 2.28), daily length of watching television (OR = 1.31, 95 % CI: 1.06 - 1.61), playing outdoors (OR = 1.32, 95 % CI: 1.16 - 1.50) and increment in the economic status (OR = 1.37, 95 % CI: 1.18 - 1.60).

Conclusion

Major risk predictors of burn injuries among the Iranian population included childhood ADHD, child’s age, watching television, playing outdoors, high economic status and flammable clothing.

Burns in South Korea: An analysis of nationwide data from the Health Insurance Review and Assessment Service

INTRODUCTION

The purpose of the study was to identify and describe the incidence of burn injuries in patients seen and treated in South Korea. Characteristics of inpatients and outpatients with burns were analyzed according to gender, age, burn site, and burn severity.

METHODS

This retrospective study examined the characteristics of a stratified sample of burn patients seen and treated in South Korea during the calendar year 2011. The sample was drawn from the national patient database Health Insurance Review and Assessment (HIRA).

RESULTS

Approximately 1.71% of the total patients in the Patient Sample of HIRA for 2011 were burn-injured patients. The numbers of patients treated for burns were 913/10(5) males (n=8009) and 1454/10(5) females (n=11,881). Nearly all of these patients (94.1%) were covered by national health insurance and the majority of these patients (80.6%) were treated as outpatients. Nearly half of the burn injuries were of the upper extremities (43.5%), and most of these injuries (71.5%) were rated as second-degree burns.

CONCLUSION

A review of the national data on patients seen and treated for burns in 2011 revealed that people in South Korea may experience higher numbers and more severe cases of burns and burn-related injuries than found in other countries. General burn prevention programs as well as gender- and age-specific prevention strategies are needed to reduce the risk of burns in this population.

Management and outcomes of children with severe burns in New South Wales: 1995-2013

BACKGROUND

As a result of improvements in injury prevention, severe burns appear increasingly uncommon in Australian children. Such injuries continue to have devastating impacts, with major consequences for the patient, their family, treating clinicians and the caring institution.

METHODS

A retrospective review was undertaken of Australian children who presented to our institution between 1995 and 2013 with burn injuries ≥30% total body surface area (TBSA).

RESULTS

Ninety children were identified. Their median age was 3.9 years and 57% (n = 52) were male. Most injuries occurred at home (n = 63) due to fires (n = 49). The majority received inadequate first aid (n = 56) and 40 became hypothermic during initial resuscitation. A total of 79% were transferred from other institutions. The median TBSA burnt was 40% and the majority of burns were full thickness (n = 51). All but nine were managed in the Paediatric Intensive Care Unit with a mean initial hospital admission of 43.5 days. Two thirds of children were intubated, over half of those prior to transfer, with 26 having an inhalational injury and 33 escharotomies. Compared with estimated fluid requirements, most children were over-resuscitated by a median of 26.9 mL/kg. There were seven mortalities. Wound infections were common (n = 65) and 36 suffered sepsis. The median number of dressing changes was 13 (range 0-100), operations were six and packed cells transfused was 95.7 mL/kg. Overall, 54 developed hypertrophic scarring and 45 scar contractures that have required subsequent reconstructive surgery.

CONCLUSION

Severe burn injuries in children have significant morbidity and mortality. They would appear expensive to manage and impact substantially on health care resources.

Incidence and causative agents of chemical eye injuries in Switzerland

CONTEXT

Chemical eye injuries are ophthalmological emergencies with a high risk of secondary complications and severe visual loss. Only limited epidemiological data for such injuries are available for many countries.

PATIENTS AND METHODS

We performed two independent studies. The cause of chemical eye injuries was assessed with a prospective questionnaire study. Questionnaires were sent to all ophthalmologists in Switzerland. A total of 163 patients (205 eyes) were included, between December 2012 and October 2014. Independent of the questionnaire study, the incidence of chemical eye injuries was assessed with a retrospective cohort study design using the database of the mandatory accident insurance.

RESULTS

Ophthalmological questionnaires revealed that plaster/cement (20.5%), alkaline (12.2%) and acid (10.2%) solutions caused the highest number of chemical injuries. Only 2% of all injuries were classified as grade III and none as grade IV (Roper-Hall classification). The official toxicological information phone-hotline was contacted in 4.3% of cases. Using data from the accident insurance, an incidence of chemical eye injuries of about 50/100 000/year was found in the working population.

CONCLUSION

Here, we present data on the involved agents of chemical eye injuries in Switzerland, and also the incidence of such injuries in the working population. This may also help to assess the need for further education programs and to improve and direct preventive measures.

Improving burn care and preventing burns by establishing a burn database in Ukraine

BACKGROUND

Burns are a challenge for trauma care and a contribution to the surgical burden. The former Soviet republic of Ukraine has a foundation for burn care; however data concerning burns in Ukraine has historically been scant. The objective of this paper was to compare a new burn database to identify problems and implement improvements in burn care and prevention in this country.

METHODS

Retrospective analyses of demographic and clinical data of burn patients including Tukey's post hoc test, analysis of variance, and chi square analyses, and Fisher's exact test were used. Data were compared to the American Burn Association (ABA) burn repository.

RESULTS

This study included 1752 thermally injured patients treated in 20 hospitals including Specialized Burn Unit in Municipal Hospital #8 Lviv, Lviv province in Ukraine. Scald burns were the primary etiology of burns injuries (70%) and burns were more common among children less than five years of age (34%). Length of stay, mechanical ventilation use, infection rates, and morbidity increased with greater burn size. Mortality was significantly related to burn size, inhalation injury, age, and length of stay. Wound infections were associated with burn size and older age. Compared to ABA data, Ukrainian patients had double the length of stay and a higher rate of wound infections (16% vs. 2.4%).

CONCLUSION

We created one of the first burn databases from a region of the former Soviet Union in an effort to bring attention to burn injury and improve burn care.

Unintentional domestic burns in Iran: Analysis of 125,000 cases from a national register

BACKGROUND

The aim of this study was to map out some epidemiological aspects of unintentional burn injuries among Iranian victims using a national injury registry data.

METHODS

Injury data were taken from a national injury surveillance system over the period 2000-2002. The study population comprised 31.5% of Iran's population. Burn-injury cases were retrieved and analysed.

RESULTS

Of all the grossly 307,000 home injuries reported during the years 2000-2002 in Iran, about 125,000 cases (41%) were unintentional burn injuries. Women comprised 58% of the unintentional burn victims. The mean age among burn victims was 19.18±19 (standard deviation, SD) years. The age-adjusted incidence and mortality rates showed that children had a much higher incidence of domestic burns but the elderly suffered higher fatality in spite of lower incidence in this age group. Overall, 65.2% of the domestic burn injuries occurred in the living rooms or bedrooms followed by 27% in the kitchen. The hands and fingers were injured in 43.6% followed by the lower limbs in 37.6%. According to injury mechanism, scalds were the most common type of burn injuries comprising 77.7% of all burns. Of all the burn victims, 791 died, 48 victims became disabled and the remaining improved or were undergoing therapy when reported.

CONCLUSION

Burns form a major health problem in Iran. Due to high mortality rate, the elderly need specific attention regarding burn prevention and treatment in this age group. Moreover, in spite of lower fatality, any prevention programme should have a focus on childhood burns mainly due to the overwhelming distribution of burns in children and the young population of Iran.

Experience with corrective surgery for postburn contractures in Mumbai, India

Postburn contracture is a source of significant morbidity in India, even though its occurrence can be reduced significantly by comprehensive postburn injury care, including surgical intervention. This study investigates whether limited access to initial medical care after burn injury has been associated with increased contracture formation among lower socioeconomic class patients in Mumbai, India. During a surgical mission in Mumbai, India, patients presenting with functionally debilitating burn contractures and minimal income were surveyed for initial care received immediately after burn injury. The survey consisted of questions regarding the history of burn injury and details of any initial treatment. Demographic data were collected by chart review. Thirty-eight patients from the state of Maharashtra participated in the study (mean age 28.1 years). The most common etiology of burn injury was from kerosene stove blasts (74%), and the most common morbidities were contractures of the neck and upper extremity. On average, time elapsed since the original injury was 2.8 years. Nearly all patients sought initial medical care at hospitals (97%) with the majority receiving only dressing changes for their full-thickness or deep-dermal burns (61%). The most common reason for not seeking out delayed burn reconstruction was perceived cost (65%). Ultimately, 60 operations were performed, of which 9 (15%) developed postsurgical complications. These data suggest that a subset of lower socioeconomic class burn patients in Maharashtra received suboptimal initial intervention. Comprehensive initial therapy after burn injury may provide better outcomes and limit the number of patients requiring delayed reconstruction.

The true cost of burn

It is difficult to define the true cost of a burns injury, however there has always been a consensus that the costs associated with burns care are high. This study aims to achieve an accurate calculation of the cost of acute burns care in an Australian context. A retrospective review of 20 adult burn patients treated at our Centre was performed. An itemized price list was prepared based on items, services and equipment actually utilized in the care of burns patients. Case records were reviewed for a count of quantities to calculate costs for each item. Regression analysis was performed to produce a cost vs %TBSA curve for cost prediction. A cost breakdown was also performed for analysis of the most significant areas of expenditure and their trends with %TBSA. The cost calculated for an average adult burns patient was AU$71,056 (US$73,532). The total cost of all 20 patients was AU$2,449,112 (US$2,534,464). %TBSA injured was confirmed as the primary determinant of cost. Hospital length of stay, operative costs, dressings and staffing were found to be the most significant components of cost and increased most prominently with %TBSA. Compared to our findings, expenditure for prevention and education programs is minimal. There is limited conclusive evidence that changes in management protocols have had successful impact on the cost of burns treatment. Future progress in burns management may effect factors such as hospital length of stay, however until such changes, resource allocation should recognize the importance of prevention and its success at reduction of injury severity for real reductions in cost of burns care.

Incidence and treatment of burns: a twenty-year experience from a single center in Germany

OBJECTIVE

To analyze trends in incidence and treatment of thermal injuries over the last two decades.

METHODS

We retrospectively reviewed our local single center database of patients with thermal injuries admitted to the burn intensive care unit (BICU) of the Cologne-Merheim Medical Center (University Hospital of Witten/Herdecke). The cohort was divided into two groups according to the decade of admission and the epidemiology and clinical course of the patient sample admitted during the period 1991-2000 (n=911) was compared to that of 2001-2010 (n=695).

RESULTS

The following variables were significantly different in the bivariate analysis: mean age (39.8 years vs. 44.0 years), burn size of total body surface area (23.2% vs. 18.0%) and size of 3rd degree burns (9.6% vs. 14.9%). The incidence of inhalation injury was significantly lower in the last decade (33.3% vs. 13.7%) and was associated with a shorter duration of mechanical ventilation (10.8 days vs. 8.5 days). The ABSI-score as an indicator of burn severity declined in the second period (6.3 vs. 6.0) contributing partially to the decline of BICU length of stay (19.1 days vs. 18.8 days) and to the mortality rate decrease (18.6% vs. 15.0%).

CONCLUSION

The severity of burn injuries during the last two decades declined, probably reflecting the success of prevention campaigns. Concerning mortality, the chance of dying for a given severity of injury has decreased.

Epidemiology of pediatric burn injuries in isfahan, iran

Background

Burns are major cause of death and disability worldwide, particularly in the developing countries.

Objectives

The aim of this study was to determine the incidence and causes of burns in children under the age of 15 years in Isfahan province, Iran.

Patients and Methods

All children admitted to the burn center of Isfahan, the largest city in central Iran, between 2007 and 2009 were enrolled in this study. We analyzed the data on age, sex, location, cause and spread of the burn, duration of admission, and cause of mortality.

Results

Out of 2229 burn patients, 1014 (45.5%) were under the age of 15, indicating an annual incidence of 50 in 100,000 children. Of the 1014 patients, 610 (60%) were boys and 404 (40%) were girls; the male-to-female ratio was 1.5:1. Most of the patients were in the age range of 3 to 6 years. Scald was the most common type of burn injury (51.8%). Six-hundred and sixty-eight cases (65.7%) were from urban areas, while 346 (34.3%) were from rural areas. Fifty-six patients (5.5%) died.

Conclusions

Burn injury is a major health concern in the pediatric age group, and specific consideration and planning are required for its management.

Household related predictors of burn injuries in an Iranian population: a case-control study

BACKGROUND

To prevent burn injuries it is vital to have sound information on predictors of its occurrence in different settings. Ardabil Province is the coldest province of Iran with high burden of burn injuries. The aim of this study was to determine the household related predictors of unintentional burns in Ardabil Province located at North-West of Iran.

METHODS

The study was conducted through a hospital based case-control design. 239 burn victims as well as 246 hospital-based controls were enrolled. Both bivariate and multivariate analysis methods were used.

RESULTS

Males comprised 55.2% of all the study subjects. Mean age of the participants was 21.8 years (95% CI: 19.17-24.4). The economic ability of the households was associated with risk of burn injuries. Multivariate conditional logistic regression results showed the following variables to be independent factors associated with burn injuries. Using non-conventional pipe-less air heaters instead of conventional piped kerosene- or gas-burning heaters (Odds ratio: 1.98, 95% CI: 1.1-3.6). Common use of picnic gas-stove for cooking at home (odds ratio = 1.6, 95%CI: 1-2.4). Using electric samovars instead of other types of samovars (Odds ratio = 0.3, 95% CI: 0.1-1). Using samovars lacking the national standard authorization mark (Odds ratio = 2.2, 95% CI: 1.4-3.6).

CONCLUSION

Using some types of specific heating or cooking appliances, and unsafe use of conventional appliances were major risk predictors of burn injuries in this population.

Changing trends in pediatric upper extremity electrical burns

BACKGROUND

Upper extremity electrical burns are a cause of major morbidity and disability in affected individuals. Anecdotally, we have noted changes in the presentation of cases to our institution. We sought to compare current data on upper extremity electrical burns in children with our previously published historical data.

METHODS

Using the Shriners Hospital Boston and American Burn Association databases, we retrospectively analyzed electrical upper extremity burns in patients aged 21 years or younger. Data regarding demographics, etiology, and reconstruction were collated and analyzed.

RESULTS

In our institutional cohort, patients were most commonly males (37/48, 77%) aged 10-15 years (19/48, 40%). We have seen a rise in the proportion of female, younger patients, with burns attributed to domestic wiring, indicative of a reduction in the number of high-voltage injuries in males due to demonstrations of bravado. High-voltage injuries correlate with severity of injury and tended to be transferred to our institution from foreign countries (9/48, 19%). We have also seen a reduction in the need to amputate extremities.

CONCLUSIONS

Changes in upper extremity electrical burn demographics and etiology since the 1970s may be indicative of effective education and safety campaigns. Consequently, reconstructive requirements have also changed. We hope that similar ongoing efforts in the developing world may bring about comparable positive results.

Epidemiology of burns in Iran during the last decade (2000-2010): review of literature and methodological considerations

The approach to burn prevention, to be effective in a particular area, should be based on sound knowledge of etiological patterns of burns injuries and must take into account the geographical variations and socioeconomic differences in burn epidemiology. Although many articles are published on burns epidemiology in Iran, a holistic view of burn epidemiology in Iran is not well presented in literature. In this study, a wide literature review was made on articles published regarding burns injuries in Iran. Pubmed, Embase, Scopus, and Iranian scientific information (SID) databases were searched for information on epidemiology of burns in Iran during the years 2000-2010. During the investigation we found that few Farsi journals were not indexed in SID during the earlier years of the decade, so to increase the chance of capturing necessary information these were checked by hand. As the second source, available data from the Iranian National Home Injury Registry Database (INHIRD) during two Iranian calendar years in the period 2001-2003 were used to extract necessary information. The results of this review helped in defining the magnitude of the burns problem, exploring the role of gender and age in burns, defining the agents causing burns, burn extent, burn mortality and place of injury occurrence. Some areas with paucity of information as well as methodological pitfalls in published research were identified and discussed.

Comic books can educate children about burn safety in developing countries

Burns in developing countries account for significant morbidity and many occur within the pediatric population. This study investigates whether a comic book can increase burn awareness in primary school age children, both domestically and abroad. Based on demographic data regarding pediatric burns in developing nations, a comic book was developed to educate primary school age children on key risk factors regarding burn safety, including teaching children to not touch active stoves, not to light fireworks without supervision, and to "stop, drop, and roll" after burn injury. Students, aged 5 to 7 years, in both West Virginia, United States (N = 74), and West Bengal, India (N = 39), answered a three-question survey regarding these issues both before and after reading the comic book. Groups were compared using Fisher's exact test and significance was defined as P < .05. Initially, students answered 67.8 and 66.9% of the questionnaire correctly overall in West Virginia and West Bengal, respectively. These scores improved to 81.6 and 99.1% (P < .01 for each group), respectively, after reading the comic as a class. Specifically, there were significant increases in both groups for the questions regarding avoiding hot stoves (P < .01) and fireworks (P < .01). The lesson required 30 minutes total per class. The teachers reported that students enjoyed reading the comic and were engaged during the sessions. This study demonstrates that a comic book has value in teaching children about burn awareness. Comic books may be a cost-effective method as an outreach tool for children.
