Epidemiological data and mortality rate of patients hospitalized with burns in Brazil

Burden of Burns in Brazil from 2000 to 2014: A Nationwide Hospital-Based Study

BACKGROUND

Burns are a major public health concern, affecting mostly low- and middle-income countries. However, there is a lack of epidemiological studies on burns in these countries, particularly in Latin American countries. Our aim was to analyze nationwide demographic, epidemiological and economic characteristics of hospitalized burn patients in Brazil.

METHODS

A retrospective study was conducted including inpatients admitted with a diagnosis of burns (ICD-10:T20-T31) from all hospitals in Brazil from 2000 to 2014. We calculated hospitalization and in-hospital mortality rates. Length of stay (LoS), charges and premature mortality were also assessed.

RESULTS

A total of 412,541 burn hospitalizations were found, with a hospitalization rate of 14.56 hospitalizations/100,000 inhabitants/year. This rate is decreasing since 2003, mostly due to the reduction among children and elderly. Children below 5 years old accounted for 24% of all admissions. In-hospital mortality rate was 8.1% and median LoS was 5 days. Mean hospitalization charge was 856 international dollars. Substantial regional discrepancies were found in several indicators.

CONCLUSION

In this first Latin American nationwide study of burn patients, a decreasing trend of hospitalization rate and a low charge contrasted with a high in-hospital mortality rate. This latter indicator, associated with a low LoS, may raise concerns regarding the quality of healthcare. Important discrepancies were found between regions, which may indicate important differences in regard to healthcare access and risk of burns. Targeting effective prevention, improving healthcare quality and providing more widespread and accurate burn registry are recommended.

Assessing burn care in Brazil: An epidemiologic, cross-sectional, nationwide study

BACKGROUND

The aim of this study was to describe the national epidemiology of burns in Brazil and evaluate regional access to care by defining the contribution of out-of-hospital mortality to total burn deaths.

METHODS

We reviewed admissions data for Brazil's single-payer, free-at-point-of-care, public-sector provider and national death registry data abstracted from DATASUS for 2008-2014. Admissions, in-hospital mortality, hospital reimbursement, and total deaths from the death registry were assessed for records coded under ICD-10 codes corresponding to flame, scald, contact, and electrical burns.

RESULTS

A total of 17,264 burn deaths occurred between 2008-2014 (mean annual 2,466 [SD 202]). Of all burns deaths 79.1% occurred out of hospital, with marked regional differences in the proportion of out-of-hospital deaths (P < 0.001), the greatest being in the North region. The mean annual number of admissions >24 hours was 18,551 (SD 1,504) with the greatest prevalence of flame burns overall (43.98%) and scalds prevailing in < 5 years (57.8%). Regional differences were found in per-capita admissions (P < 0.001) with the greatest number in the Central-West region. A mean of $1,022 (SD $94) US dollars was reimbursed per burn admission.

CONCLUSION

Given that nearly 80% of burns mortalities occurred out of hospital, prevention of burns alongside interventions improving prehospital and access to care have potential for the greatest impact.

Xenogeneic Mesenchymal Stromal Cells Improve Wound Healing and Modulate the Immune Response in an Extensive Burn Model

Major skin burns are difficult to treat. Patients often require special care and long-term hospitalization. Besides specific complications associated with the wounds themselves, there may be impairment of the immune system and of other organs. Mesenchymal stromal cells (MSCs) are a recent therapeutic alternative to treat burns, mainly aiming to accelerate the healing process. Several MSC properties favor their use as therapeutic approach, as they promote angiogenesis, stimulate regeneration, and enhance the immunoregulatory function. Moreover, since patients with extensive burns require urgent treatment and because the expansion of autologous MSCs is a time-consuming process, in this present study we chose to evaluate the therapeutic potential of xenogeneic MSCs in the treatment of severe burns in rats. MSCs were isolated from mouse bone marrow, expanded in vitro, and intradermally injected in the periphery of burn wounds. MSC-treated rats presented higher survival rates (76.19%) than control animals treated with PBS (60.86%, p < 0.05). In addition, 60 days after the thermal injury, the MSC-treated group showed larger proportion of healed areas within the burn wounds (90.81 ± 5.05%) than the PBS-treated group (76.11 ± 3.46%, p = 0.03). We also observed that CD4(+) and CD8(+) T cells in spleens and in damaged skin, as well as the percentage of neutrophils in the burned area, were modulated by MSC treatment. Plasma cytokine (TGF-β, IL-10, IL-6, and CINC-1) levels were also altered in the MSC-treated rats, when compared to controls. Number of injected GFP(+) MSCs progressively decreased over time, and 60 days after injection, few MSCs were still detected in the skin of treated animals. This study demonstrates the therapeutic effectiveness of intradermal application of MSCs in a rat model of deep burns, providing basis for future regenerative therapies in patients suffering from deep burn injuries.

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.

Epidemiological study of burns in Komfo Anokye Teaching Hospital, 2006-2009

AIM

To identify and describe the patterns of burns reported at the Komfo Anokye Teaching Hospital (KATH) from 2006 to 2009 and their outcomes on the various age groups and genders.

METHODS

Patients' records from admission and discharge books of the Burns Intensive Care Unit, Polyclinic Casualty Consulting Rooms and from the Statistical Department of KATH were reviewed to obtain the necessary data for this retrospective study. Data entry and analysis were done by using SPSS version 17.0.

RESULTS

A total of 731 patients' records were reviewed, with male to female ratio of 1.2:1. The mean age was 15.83 years; range was 0-79 years. Children less than 10 years were the most frequently admitted group (53.5%). Most of the burns occurred in domestic settings (88.5%), whiles, majority of the burns were accidental (98.8%). Scalds (57.4%) were the most frequent cause of burns followed by open flame (38.2%). The mortality rate was 13.1% for the period under review. Majority (71.4%) of the patients spent less than 10 days on admission. The mean total body surface area (TBSA) was 24.79%, and there was significant correlation between TBSA, age group, outcome and duration of hospital admission.

CONCLUSION

Children less than 10 years were the most vulnerable victims to burns; males dominated the number of victims. The commonest aetiological factor was scalds, with most of them related to inattention from parents. More dedicated burn surgeons and properly trained nurses are needed at KATH. Ambulance and pre-hospital services should be increased with adequate number of paramedics. Coordination between district hospitals and tertiary burn centres should also be established, for the proper transfer of burn cases to the tertiary burn centres, especially KATH.

Epidemiological and clinical profile of burn victims

OBJECTIVES

To describe the clinical and epidemiological profile of the patients in the Burn Unit of the Hospital Universitario San Vicente de Paúl (HUSVP) de Medellín, Colombia, from 1994-2004.

METHODS

Retrospective descriptive study of all pediatric and adult burn patients. The following were recorded: age, gender, cause, extent and severity of the burns, time in the hospital, operations, complications and death rate. Statistica 6.0 (Stafsoft Inc.) was used.

RESULTS

Two thousand three hundred and nineteen patients were admitted, 66.8% were males and 62.9% were less than 15 years old. Burns caused by scalding were the most frequent (45.9%) followed by flames (38.5%) The average burn area was 26.9%. Average hospital stay was 26.9 days. In 2004, 40.4% of the patients required surgery; 13.4% of the patients had complications. 7.4% of the patients died, with an average burn area of 62%; burns caused by flames accounted for 63% of the deaths.

CONCLUSIONS

There is a continuing improvement in hospital stay, survives burn sizes, with figures comparable to others without access to a tissue bank or skin cultivation.

Burns in low- and middle-income countries: A review of available literature on descriptive epidemiology, risk factors, treatment, and prevention

Burn prevention requires adequate knowledge of the epidemiological characteristics and associated risk factors. While much has been accomplished in the areas of primary and secondary prevention of fires and burns in many developed or high-income countries (HICs), such as the United States, due to sustained research on the descriptive epidemiology and risk factors, the same cannot be said of developing or low- and middle-income countries (LMICs). To move from data to action and assist preventive efforts in LMICs, a review of the available literature was conducted to assess the current status of burn preventive efforts. A MEDLINE search (1974-2003) was conducted on empirical studies published in English on the descriptive epidemiology, risk factors, treatment, and prevention of burns in LMICs. Review of the 117 identified studies revealed basically the same descriptive epidemiological characteristics but slightly different risk factors of burns including the presence of pre-existing impairments in children, lapses in child supervision, storage of flammable substances in the home, low maternal education, and overcrowding as well as several treatment modalities and preventive efforts including immediate application of cool water to a burned area. Continuous evaluation of promising interventions and those with unknown efficacy that have been attempted in LMICs, along with testing interventions that have proven effective in HICs in these LIMC settings, is needed to spearhead the move from data to action in preventing burns in LMICs.

Suicide trends and characteristics in Brazil

Brazil is the largest and most populous country in South America (in 2002 the population was approximately 175 million). Although life expectancy in Brazil has increased, suicide and other forms of injury-related mortality, such as homicide and accident, have increased as a proportion of overall mortality (Oswaldo Cruz Foundation, 1984; Brazil Ministry of Health, 2001). The suicide rate in Brazil (3.0–4.0 per 100 000 inhabitants) is not considered high in global terms (World Health Organization, 1999). Nevertheless, it has followed the world tendency towards growth: during 1980–2000, the suicide rate in Brazil increased by 21%. Elderly people present the highest suicide rates in absolute numbers, but the alarming finding in the Brazilian data is that the youth population is increasingly dying by suicide (Mello-Santos et al, 2005). This statistic partially confirms a forecast by Diekstra & Guilbinat (1993) that the number of deaths by suicide would dramatically increase over the next decades, mainly in developing countries, including Latin America. In these regions, socio-economic factors (such as an increase in divorce and unemployment and a decrease in religiosity) increase the risk of self-harm. We discuss the reasons for the low suicide rate in Brazil and highlight the socio-economic factors affecting its increase among the youth population in particular.

A retrospective analysis of 19,157 burns patients: 18-year experience from Hallym Burn Center in Seoul, Korea

This is a retrospective, epidemiological study of 19,157 acute burn patients admitted to the Hallym Burn Centre, Hangang Sacred Heart Hospital, Seoul, Korea, during the period 1986-2003. The study was conducted to identify characteristics of burn patients that could lead to development of preventive programs to reduce both the frequency and mortality of burn injury. The majority of patients admitted had relatively minor burns, which were treated conservatively. Males predominated in all age groups with a summer peak seasonal variation. Typical burn in the children <5 years of age was a scald injury, occurring at home, affecting upper limbs and resulting in a relatively short hospital stay. Electrical burns due to steel chopsticks and steam burns due to electric rice cookers were also found in this age group. Adult burns, affecting upper and lower limbs, were caused by flames, hot liquids or electricity. Burns were sustained at the workplace and outdoors. Flame accidents in males were the leading cause of death with overall mortality of 8.2%. 13.9% of admissions needed intensive care and average length of hospital stay was 32.6 days. The annual number of patients undergoing burn related surgery has continuously increased reflecting a more aggressive surgical management. Our ongoing efforts are to promote prevention program and look for changes in the incidence of burn injury based on these epidemiologic features. Further study for implications of changes in management protocols and policies on treatment outcomes would improve the provision of appropriate care for the patients.

Epidemiology and mortality of hospitalized burn patients in Kohkiluye va Boyerahmad province (Iran): 2002–2004

The Kohkiluye va Boyerahmad province is located in the south of Iran. The population of the province is about 615,000, living in 14,261 km(2). The total number of patients in the study was 235. There were admitted to the burn unit of Shahid Beheshti hospital (Yasuj) between 18 July 2002 and 17 July 2004. Of these patients, 149 (63.4%) were accidental and 86 (36.6%) were self-inflicted burns. The hospitalization rates for accidental and self-inflicted burns were 12.1 and 7.0 per 100,000 person-years, respectively. There is a significant difference in the sex ratio (males:females) between accidental (1.40) and suicidal (0.13) patient groups (P((2))<0.00001). The fatality rates for accidental and self-inflicted burns were 2.1 and 59.5%, respectively. The mortality rates for accidental and self-inflicted burns were 0.24 and 3.81 per 100,000 person-years, respectively. The overall mean and median ages for accidental patients were 19.4 and 13 years, and those for self-inflicted burns were 24.9 and 23 years, respectively. In the accidental patients, the BSA of the burns ranged from 5 to 95%, with a median of 15%. In the self-inflicted patients, the median of BSA was 65%. The majority of accidental burns were caused by scalds (43.2%) and of self-inflicted burns by kerosene (87.5%). The median hospital stay was 8 days with a range of 1-43 days for accidental patients. The median hospital stay was 4 days with a range from <1 to 36 days for fatal self-burning patients. In non-fatal self-burning cases, the median hospital stay was 20 days with a range of 4-53 days. There is significant difference between fatal and non-fatal self-burning cases for hospital stay (P((2))<0.0001). No definite correlation was found between the incidence of either accidental or self-inflicted burns and seasons (P((2))>0.05). Most of the burns occurred at home.

A global study of hospitalized paediatric burn patients

The global incidence of hospitalized paediatric burn patients is unknown. In order to determine a working estimate of the size of the problem, one approach is to extrapolate from relevant published studies. A literature search of the Medline database was performed to identify epidemiological papers published since 1990, which addressed paediatric burn admissions. Extrapolation from population-based studies allowed global figures to be estimated. The highest incidence of hospitalized paediatric burns patients is in Africa, the lowest in the Americas. Europe, the Middle East and Asia share similar figures, but the considerably larger population of Asia indicates that it bears over half of the world's paediatric burn population. It is unfortunate that despite many published studies describing burn admission, few meet criteria that allow for comparative epidemiological data. More attention needs to be focused on uniformity in data collection and presentation to enhance the value of the data available.

A Seven-Year Burn Unit Experience in Kayseri, Turkey: 1996 to 2002

A retrospective multifactorial epidemiological study of 742 patients admitted to Erciyes University Medical Faculty Burn Unit during a 7-year period between 1996 and 2002 is presented. The overall male-to-female ratio was 1.88:1. The highest-risk age group of burn injuries was 0 to 6 years (48.6%), with the greatest number of injuries occurring to children who were 2 to 3 years of age. Seasonal variations had no influence on the increased number of admissions to the burn unit. Scalding was the major cause of pediatric burns. Flame burns were the most frequent cause of burns in adults and the second-leading cause in children. Seventy-eight of the 742 patients died, with a mortality rate of 7.8 % in children and 12.6% and 19.23% in adult males and females, respectively. The overall mortality rate was 10.5%.

Self-Inflicted Burns in Athens, Greece: A Six-Year Retrospective Study

Self-inflicted burns represent a major social and medical problem. The aim of this study was to record the epidemiology, mortality and etiology of suicide attempts by burning, in Athens, Greece. Over a 6-year period from April 1997 to April 2003, all the medical charts of the patients who were admitted to the Burn Center of the General State Hospital of Athens, Greece, with self-inflicted burns were retrospectively studied. Of the 1435 burn patients, 53 (3.69%) had attempted suicide by self-inflicted burn. Their ages ranged from 18 to 90 years old (mean 53.5 years). Females (57%) outnumbered males (43%). The mean total body surface area (TBSA) burned was 41.6% (range: 15-100%). The overall mortality rate was very high (75.4%). A preexisting psychiatric disorder was present in 43.3% of the patients. In conclusion, the extent and the depth of the burn injuries could explain the high mortality rate seen in these patients, in correlation with their negativism to the treatment. Burn care professionals should be familiar with self-inflicted burn patients who constitute a considerable proportion of major burns and require constant psychiatric support in addition to burn care.

Intentional burn injury: an evidence-based, clinical and forensic review

Burn injury can be inflicted intentionally either by one person to another whenever one has the ability to physically control the other, or it can be self-inflicted. There is scant evidential basis for much that is written about and practiced in the evaluation and care of patients that have sustained intentional burn injuries. Yet this is an area in which medical personnel must necessarily be trained in both the therapeutic and forensic aspects of a complex problem. Failure to appreciate the complexity of medical and forensic interactions may have far reaching effects. A missed diagnosis can result in inappropriate medical care, on-going abuse and future fatality. Inept management can result on the one hand, in blame levelled inappropriately placing incomparable strain on family units and innocent parties, and on the other, allow abusers to continue unchecked. This is the first review on the subject in which lawyers and doctors collaborate to produce a holistic approach to this subject. In it we describe the legal considerations that medical staff must appreciate when approaching patients who may have suffered intentional burns. We analyse the various scenarios in which intentional burning can be found and challenge the clinical dogma with much of the management of paediatric inflicted burns has become imbued. We suggest a rational and balanced approach to all intentional burn injuries-especially when children are involved. In the light of current case law in which dogmatic medical evidence has been implicated in wrongful convictions for child abuse in the UK, it is imperative that medical professionals gather evidence carefully and completely and apply it with logic and impartiality. This paper will aid clinicians who may not be experienced in dealing with burn injuries, but find themselves in the position of seeing a burn acutely, to avoid common mistakes.

Adult burn injuries in an Emergency Department in Central Anatolia, Turkey: a 5-year analysis

PURPOSE

Burn injuries require a multidisciplinary approach. Emergency Departments can play vital roles in the treatment of burns. The purpose of this study is to investigate the epidemiological and clinical characteristics of the adult burn patients admitted to our Emergency Department and to determine the frequency of the patients who were treated on an outpatient basis and discharged from the Emergency Department.

PROCEDURE

A retrospective review of 314 adult burn patients who presented to the Emergency Medicine Department of Erciyes University Hospital from January 1996 to December 2000.

FINDINGS

Sixty-four percent of the patients were male. Mean age was 32.9+/-14.7. Ninety-nine patients (32%) had moderate to major burns. The highest numbers of patients were in the 21-30 age group. Flame burns comprised the majority of presentations and admissions (48 and 69%, respectively). Thirteen patients had associated injuries (4%). Eighty-seven patients (28%) were hospitalized, 21 of these died. Death occurred mostly from respiratory failure and sepsis. Domestic accidents were the leading mechanism (63%).

CONCLUSION

Burns were mostly due to accidents arising from carelessness, ignorance, hazardous traditions and improperly manufactured products. These can be prevented through mass education programs countrywide. Because almost all burn patients present to Emergency Departments first and not all hospitals can employ burn specialists, the patients with minor burns can be treated on an outpatient basis and the treatment of severe burns can be effectively initiated by emergency physicians.

Burns in Southern Turkey: Electrical Burns Remain a Major Problem

In Turkey, burns represent a relatively small number of injuries overall, but they continue to be a major public health problem. Our aim in this study was to identify risk factors that affect outcome in burn patients hospitalized in the southern part of our country, with special emphasis on electrical burns. The database for 109 burn patients who were admitted to our burn center from April, 2000, through August, 2001, was retrospectively analyzed. Electrical injury was the cause of burn in 23 (21%) of the 109 cases. The burn causes differed among age groups and between the sexes, with males constituting 95% of the electrical burn patients. The mortality rate for the electrical burn group was lower than the rate for the rest of the burn patients (1/23 vs 17/86, respectively; P <.001); however, the opposite was true for complication rate (10/23 vs 5/86, respectively; P <.001), cost of treatment (8351 US dollars vs 5122 US dollars, respectively; P =.009), and length of hospital stay (39.9 vs 26.2 days, respectively; P < 0.001). The rate of electrical burn injury in Turkey has changed very little in the past two decades. This underlines the need for stronger efforts aimed at prevention, such as better public education and strict regulations regarding the distribution and use of electricity.

Epidemiology of hospitalized burns patients in Taiwan

Previous studies based on either single hospital data or sampling of specific groups of hospitalized burns victims in Taiwan have provided only minimal epidemiological information. The study is designed to provide additional data on the epidemiology of hospitalized burns patients in Taiwan. Data were obtained from the Burn Injury Information System (BIIS), which brings together information supplied by 34 contracted hospitals. The study time course spanned a 2-year period from July 1997 to June 1999. Patient characteristics (age, sex, education level, etc.), causes and severity of injuries, and medical care measures were explored. A total of 4741 patients were registered with BIIS over the study period. The majority of hospitalized patients (67%) were male. The age distribution of burns patients showed peaks occurring at the age groups of 0-5 and 35-44 years. Over the time course of a day, burn injuries occurred more frequently from 10:00 to 12:00 h and 16:00 to 18:00 h. Injuries suspected as the result of suicide, homicide or child abuse accounted for 4.8% of hospitalized cases. More than 48% of the burns occurred in the home. The leading type of burn injury was scalding, followed by naked flame, explosion, electrical burns, and chemical burns due to caustic or corrosive substances. The mean percent total body surface area (%TBSA) for adults was 19%, and for young children was 12%. The average length of hospital stay was 18 days. In conclusion, children under 5 years and adults between 35 and 44 years of age are two high-risk groups for burn injuries. Corresponding to meal preparation time, hot substances such as boiling water, hot soup, etc. are the most common agents responsible for scalds. Prevention programs for reducing the risk of burn injuries during cooking and eating are required, especially for parents with young children.

Mortality rates among 5321 patients with burns admitted to a burn unit in China: 1980-1998

A retrospective study was conducted on 5321 burn patients hospitalized in a burn center in Jinzhou, China during the period 1980-1998. Of the 5321 patients, 57.8% were between 15 and 44 years old and 3.4% were > or =60 years old. Ninety-six percent had burns covering less than half of body surface area and 31.7% had only full thickness skin burn. The number of patients in the 1990s was three times that of the 1980s. Overall mortality rate was 0.86%. LA(50) for total body burn area (TBSA) and only full thickness skin burn (FTSB) was 94 and 87%, respectively. The high survival rate, may relate primarily to the low percentages of older patients and of patients with severe burns. Inhalation injuries, infection and MOD are the main causes of deaths in our patients and would be key targets to improve clinical care and in future study.

Epidemiological study of self-inflicted burns in Tehran, Iran

Self-inflicted burns have been considered a serious mental health problem throughout the world and especially in economically developing countries. The aim of this study was to identify the epidemiologic features and current etiological factors of suicide by burning in Tehran, Iran, to develop effective prevention programs. Over a period of 2 years from March 1997 to March 1999, of the 1,236 patients aged 14 years and older who were admitted to Tohid Burn Center in Tehran, Iran, 110 (8.9%) had attempted suicide by self-immolation. The median age was 25 years (range: 14-68 years) and the median extent of the burns was 71% TBSA (range: 20-100%). Forty-eight patients had a previous psychiatric diagnosis (43.6%). Depression was the most common psychiatric diagnosis by history. The method most commonly used was a flame with the addition of a flammable liquid (frequently kerosene). Also, most of the patients (70%) were of a low socioeconomic class. Overall, self-inflicted burns should be considered an increasing mental health problem in our society. Therefore, it is necessary to implement prevention programs and strategies to reduce the incidence rate of this problem.

Analysis of 1089 burn patients in province of Kurdistan, Iran

Burn injuries still produce a significant morbidity and mortality in Iran. This study was carried out to analyze the epidemiology, mortality, and current etiological factors of 1089 burn patients in the province of Kurdistan in the west of Iran during the 6 years from 21 March 1994 to 20 March 2000. There were two burn centers in Kurdistan, serving 1.4 million people in an area of 28,000 km(2). The incidence rate of burn hospitalization was 13.5 per 100,000 person-years. The median age was 18 years with 58% of the patients under 20 years. The median Body Surface Area (BSA) burned was 40%. Incidence rate of burns for females was 18 per 100,000 person-years and 9.1 per 100,000 person-years for males (P((2))<0.000001). Also there was a statistically significant association between mortality rate and age groups/gender/BBS (P((2))<0.000001). Flame was the most common type of burn (694/1089, 63.7%). There was also a significant correlation between the age groups and types of burn (P((2))<0.000001). Ninety-one percent (991/1089) of the burns were unintentional (12.3 per 100,000 person-years), while suicide attempts by burning for the population aged 13 and older accounted for 12.7% (98/771) (2 per 100,000 person-years). The mortality rate was 4.5 per 100,000 person-years. The study results provide a valuable baseline by which to assess future efforts directed toward the prevention of burn injuries in Kurdistan.

Four years of burn injuries in a Red Cross hospital in Afghanistan

This study examines the epidemiology and mortality of patients admitted with burns to a Red Cross hospital in Afghanistan between 1996 and 2000. Three hundred and eighty-eight cases were reviewed retrospectively (57% male, 43% female) with a median age of 8 years. Sixty-three percent were children. Scalds (44%) were the commonest injury followed by fire (37%). The median total body surface area burned (TBSA) was 15%. Forty-six percent of the patients required surgical debridement and 11% underwent delayed skin grafting. Overall, median duration of stay was 7 days. The mortality rate was 16% (M:F, 1.1:1) and fire was the commonest cause of fatal burns. The median TBSA of fatal burn was 40%. There were no survivors with burns greater than 45% TBSA. Multiple organ failure and sepsis were the cause for most of the deaths.

Risk factors for burns in children: crowding, poverty, and poor maternal education

OBJECTIVE

To characterize the presentation of burns in children and risk factors associated with their occurrence in a developing country as a basis for future prevention programs.

DESIGN

Case-control study.

SETTING

Burn unit of the National Institute of Child Health (Instituto Nacional de Salud del Niño) in Lima, Peru.

METHODS

A questionnaire was administered to all consenting guardians of children admitted to the burns (cases) and general medicine (controls) units during a period of 14 months. Guardians of patients were questioned regarding etiology of the injury, demographic and socioeconomic data.

RESULTS

740 cases and controls were enrolled. Altogether 77.5% of the cases burns occurred in the patient's home, with 67.8% in the kitchen; 74% were due to scalding. Most involved children younger than 5 years. Lack of water supply (odds ratio (OR) 5.2, 95% confidence interval (CI) 2.1 to 1 2.3), low income (OR 2.8, 95% CI 2.0 to 3.9), and crowding (OR 2.5, 95%CI 1.7 to 3.6) were associated with an increased risk. The presence of a living room (OR 0.6, 95% CI 0.4 to 0.8) and better maternal education (OR 0.6, 95% CI 0.5 to 0.9) were protective factors.

CONCLUSIONS

To prevent burns interventions should be directed to low socioeconomic status groups; these interventions should be designed accordingly to local risk factors.

Epidemiological data of patients hospitalized with burns and other traumas in some cities in the southeast of Brazil from 1991 to 1997

This retrospective analysis of burn patients and victims of other forms of trauma from Ribeirão Preto and nearby cities admitted to hospitals in the city of Ribeirão Preto, São Paulo, Brazil, was carried out to determine the frequency of injuries of all types in order to identify the extent of the problem of burns relative to other forms of trauma. Data concerning 921 patients with burns and 60,344 patients with other traumatic injuries hospitalized during the period from 1991 to 1997 are described. Burns corresponded to 1.5% of the total number of traumatic injuries. When data are reported as absolute numbers or as incidence rate of hospitalized burn patients, burns were two times more frequent among men in most age groups. The case fatality ratio due to burns was 8.4% (77 deaths among 921 patients), with a rate of 6.4% for men and 12.2% for women. The case fatality ratio was higher among women than men regardless of the city of residence. The case fatality ratio was 3.2 and 4.4 times greater for men and women burn victims from other towns than for burn victims from Ribeirão Preto, indicating the need for additional equipment and training of medical and paramedical personnel in the initial measures to be taken with burn patients.

Epidemiology of childhood burn injuries in Fars province, Iran

Childhood burn injuries are a major environmental agent responsible for significant morbidity and mortality in Iran. Thus, the objective of this study was to analyze the epidemiology and current causative factors of hospitalized burn injuries among the approximately 1.6 million children between the ages of birth through 15 years residing in the Fars province of Iran. These data will be used as a basis for developing a targeted preventive program to protect children from burns. Epidemiologic data for 760 children, aged 0 to 15 years, admitted to the two burn centers of Shiraz University of Medical Sciences, over a 4-year period, 1994 to 1998, were collected and analyzed. The overall hospitalization rate was 11.8 per 100,000 person-years (PY). The sex ratio (boys/girls) was 1.38. About 60% were children aged 7 years or younger. Children aged 2 years had the highest burn incidence rate (36.9/100,000 PY). A total of 77.4% of the children had body surface area burns less than 40%. Scalds accounted for 46.2% of the burns, whereas 42.9% were caused by flame. Most of the burn injuries occurred at home (93%). There were 31 burns from suicide attempts among children aged 11 to 15 years (1.4/100,000 PY), showing a major public health problem for these children in our society. During the period of the study, 131 children died of the consequences of burns (2/100,000 PY). The epidemiology of childhood burn injuries in the Fars province is similar to that reported in other economically developing countries. It is suggested that a public health education campaign on this issue would help to reduce the incidence of childhood burn injuries in this region.

Epidemiology and mortality of burns in the South West of Iran

Burn injuries still produce a significant morbidity and mortality in Iran. This study was carried out to analyze the epidemiology, mortality, and current etiological factors of 2043 burn patients who were admitted to the burn centers in the Fars province during 4 years (1994-1998). There were two burn centers in the Fars province serving 3817036 people over an area of 124,000 km(2). The overall incidence rates of hospitalization and death were 13.4 and 4.6 per 100000 person-years. The mean age was 21.9 years, and 51% of patients were children under 19-years-old. The highest rates of hospitalization and death were observed in the elderly (80 years). Also young females (20-29 years) had a high rate of hospitalization. Thus, 55% of the patients had BBS less than 40%. Burn injuries were more frequent and larger with higher mortality in females than in males (P<0.0001). There was also statistically significant correlation between age groups, gender, and BBS with mortality rate (P<0.0001). Flame was the most common etiology of burns. There was also significant correlation between age groups and type of burns (P<0.0001). Suicide attempts for all the patients > or = 11 years were the cause of 41.3% (256/620) of the burns involving women and of 10.3% (40/388) of the burns involving men. The overall case fatality rate was 34.4%. The mortality rate was significantly higher for self-inflicted burns (78%) than for accidental burns (26.7%). Most of the lesions requiring hospital admission occurred during the winter months. Factors associated with an increase in mortality were suicidal burns, burn size, age, and flame burns. Most of the burn injuries were caused by domestic accidents and were, therefore, preventable.

An epidemiological study of 1063 hospitalized burn patients in a tertiary burns centre in Hong Kong

A total of 1063 acute burn patients were admitted to the Burns Unit of Prince of Wales Hospital, Hong Kong between March 1993 and February 1999. There were 678 males and 385 females with a male to female ratio of 1.76:1. The median age was 13.1 year-old and the median burn size was 6% total body surface area (TBSA). Pediatric patients under the age of 15 year-old accounted for 550 (51.7%) admissions and 235 (42.7%) of them were toddlers <2 year-old, while adult patients of age above 15 year-old accounted for the other 513 (48.3%) admissions. There was no seasonal variation in admission. Domestic burns resulted in 756 (71.1%) injuries followed by industrial burns that caused 175 (16.5%) admissions. The median hospital stay was 9 days and 54 patients (5.1%) had inhalation injury requiring intubation and ventilatory support. Twenty-four patients died in this series which yielded a mortality rate of 2.3%. The median age for this mortality group was 46.6 year-olds with a median extent of burns of 68% TBSA. There were 16 males and 8 females with a male to female ratio of 2:1. Eighteen (75%) patients had flame burns and 15 (83.3%) of them had inhalation injury. The mortality group had significantly larger burn size (P<0.001), higher incidence of inhalation injury (P<0.001) and older age (P<0.001) compared to the survivors.

A Prospective study on the epidemiology of burns in patients admitted to the Harare burn units

The purpose of this study was to record the causes and the magnitudes of burn injuries prospectively and to evaluate the outcome of treatment of patients admitted to the burn units in Harare. The median age of the 451 patients included was 6 years (range: 1 month to 71 years), 54% were female and 46% male. The burn injuries were caused by flame in 51% of the cases and hot liquids in 47%. The overall median total body surface area burnt was 13% (range: 0.5 to 99%). Parasuicidal burns (attempted suicides) were noted in 11% of the patients with a median total body surface area burnt of 30% and mortality of 73%. Lodgers were overrepresented in the material. Delayed split skin grafting was done on 26% of the patients and early primary excision and skin grafting on 3%. The overall median hospital stay was 15 days (range: 0 to 229 days). The median hospital stay for patients with delayed split skin grafting was 42 days and that for those with primary excision and split skin grafting was 17 days. The overall mortality was 22%. All patients with burns larger than 65% of the total body surface area died. Burn injuries were more frequent and larger with higher mortality in females than in males. Flame was the major cause of the burns. Self-inflicted burns, noted mainly in young women, resulted in 73% mortality. Primary excision and grafting reduced hospital stay by 60% compared to delayed skin grafting.
