The Total Number of Burn Injuries in a Scandinavian Population

The treatment of burn injuries must be on two fronts. Within surgical treatment great advances have been made, and the next improvements must doubtless be made in the form of better prophylaxis.

There is an ample literature on this subject, but most analyses are based upon the study of in-patients, while little is known about the total frequency of burn injuries in a general population.

In the municipality of Copenhagen the treatment of burns has been centralized for 50 years, and the municipality comprises a well-defined geographical area with a population of 700,000 who must be considered representative of the whole of Denmark.

For social and insurance reasons even the slightest injuries are treated by doctors, and there is a possibility of recording all persons who have sought medical aid for burn injuries.

Burn injuries entail 8 deaths per annum, while 230 persons require admissions, 650 patients are treated in the out-patient department for burns and 1400 in other casualty wards, while the general practitioners treat 600 burn injuries every year.

Out of 85,000 annual injuries, burns make up 2.7%, and a total of 2900 persons, or 0.4% of the population, seek medical aid for burn injuries every year.

Two-thirds of the burn injuries occur in the homes and one-third in the workplaces. 23% of the victims are children under 5 years of age, in spite of the fact that children of this age make up only 6% of the population. 10% are school children and 60% are adults. In the age range over 60 only 6% sustain burn injuries, although this age group constitutes 21% of the Copenhagen population.

The causes of the various burn injuries are analysed. 55% are scalds, 21% are fire burns, 16% are contact burns, and 2% electricity accidents. Corrosions are found in 6%.

The prevention applies particularly to young children who should not be allowed to play in the kitchen or washing place. The accidents in workplaces can hardly be reduced. After conversion of the present figures to apply per 1 million of the population, they are compared with the findings of previous authors whose materials are characterized by being derived from in-patients and thus include a larger number of children and a larger number of burns caused by fire. Our material includes only a few children whose clothes have caught fire; most of these cases are due to playing with matches.     

The total number of burn injuries in a Scandinavian population—a prospective analysis

During the period 1 September 1982 to 31 August 1983 the total number of burn injuries in the municipality of Copenhagen was recorded prospectively. The social changes and the constitution of the population are illustrated.

The total number of burn injuries showed a decrease of 33 per cent compared to the investigation in 1974/75. Scalds are still the most frequent cause of burn accidents, small children are especially vulnerable. Seventy-two per cent of all accidents occurred at home. Only a few patients required ‘antishock’ therapy. No patients with work-related burn injuries died.

Preventive measures have eliminated or reduced the number of some types of thermal injury.     

Profile of the paediatric burn patient in a Canadian burn centre.

Five hundred and eighty-three children (0-18 years old), consisting of 33.4 per cent of all burn inpatients, were admitted to the University of Alberta Hospitals over an 11-year period (January 1978 to December 1988). Demographic and outcome variables, in addition to aetiological factors, were examined. 48.4 per cent of burns occurred in children less than 4 years of age, with males predominating in every age group (P less than 0.001). Children had smaller burns, a higher incidence of scalds, less inhalation injuries and a lower mortality compared to adult burn patients admitted over the same time period (P less than 0.05). There was a low incidence of confirmed child abuse by burns (1.4 per cent). High-risk environments identified were the home (74.6 per cent of burns) and recreational settings (12.4 per cent of burns), mainly occurring around campfires. Native children were overrepresented in the burn population compared to the general population by a factor of approximately 10:1. Scald prevention, high-risk environments (home and recreational), high-risk populations (male and natives) and unsafe practices with flammable liquids (petrol in particular) should be emphasized in paediatric burn prevention programmes.     

The last 10 years in a burn centre in Ankara, Turkey: an analysis of 5264 cases

This is a retrospective study analysing 5264 patients treated in the burn centre at Gülhane Military Medical Academy from 1 January 1986 to 31 December 1995. Our burn centre is not only the firs, but one of the best established and supported in Turkey. Our present study has the largest patient group of other previously published studies from Turkey. Of the total patients studied, 4464 patients had minor burns and were treated on an outpatient basis and 800 patients had moderate to major burns. Although our centre is in a military area in Ankara, only 1047 (20 per cent) patients were military personnel and the military-related burn causes comprised only 6 per cent of the total. The remaining 4217 (80 per cent of the total patients) were civilians. Flame injuries were also more frequent in military patients than civilians. Minor burns were most common in the age group 0–10 years old (40 per cent) and moderate to major burns in the age group 21–30 years (54 per cent). Scalds were the main cause of paediatric burns. Male patients were dominant. The overall mortality among inpatients was 18.2 per cent and mean total body surface area (TBSA) was 57.6 per cent in patients who died. 134 patients demonstrated inhalation injury and 82 per cent of these patients died. The epidemiological pattern of our patients is similar to that in other studies from developed countries, although some ethnic causative factors could be found. Our study indicates that emergency measures should be taken to prevent flame injuries at military barracks and industrial workplaces and scalding accidents to children at home and throughout the country.     

Burn injuries in the Dong Bei area of China: a study of 12,606 cases.

This survey analyses data from nine Chinese burn units with respect to age, causes, severity of burn injury, and survival or death of patients admitted to hospital during the past 10 years (from January 1980 to December 1989). Of 12,606 burned patients treated, 3391 were children (26.9 per cent) and over half the children (52.3 per cent) were up to 4 years old. Almost 60 per cent of the 12,606 patients treated were in the young adult group (15-44 years), and 86.9 per cent of 12,606 patients sustained thermal injuries mainly from fire flames followed by scald injuries (40.7 per cent). About 93 per cent of the patients had burns covering less than 50 per cent of the body surface area. The overall mortality rate was 1.24 per cent. The LD50 for the 12,112 patients less than 60 years old was a burned surface area exceeding 80 per cent of the total body surface area.     

Trends in burn admissions in Scotland during 1970–1992

This retrospective study involved analysis of the data of the inpatients discharged with a diagnosis of burns, from various hospitals in Scotland, during the period 1970–1992. There were 51350 such inpatients all over Scotland, with an average annual rate of 2233 cases. Overall burn incidence in actual numbers was 43.7 per cent in < 15 year olds, 41.2 per cent in 15–64 year olds and 15.1 per cent in ≥ 65 year olds. Burn rates per 100 000 population were highest in < 15 year olds and lowest in 16–64 year olds.

The pattern of burn admissions has changed. Since 1987 the highest numbers of burn inpatients were the 16–64 year olds, followed by children, then the elderly. There has been a gradual but sustained fall in burns admissions in all age categories. The downward trend was statistically significant (t = 8.48, 21 d.f., P < 0.001). Though the population of the elderly (≥ 65 year olds) increased by about 13 per cent, the burn admissions and all deaths due to burns did not reveal an upward trend. The population of the old (81 + year olds) increased by 60 per cent during the same period. The incidence of burns was above average when > 80 year olds were considered separately, approaching the levels found in children. However the rate and incidence of burns in the 65–80 year olds resembled that of the younger age group (16–64 year olds).

The total number of deaths due to burns and/or smoke inhalation has declined in all age groups and the decline has been statistically significant (chi-squared = 19.62, 1 d.f., P < 0.001). Maximum number of deaths occurred in ≥ 65 year olds (44 per cent), followed closely by 16–64 year olds (43.5 per cent), and 12.5 per cent of deaths in adolescents and children. The decline was due to improved management of burns and a decrease in the number of patients having large body surface area burns.     

Aetiology of burn injuries among children aged 0-4 years: results of a case-control study

During the year 1987/1988 a case-control study was conducted, by means of a postal questionnaire, among parents of children aged 0-4 years. Cases (n = 122) were 0-4-year-old Dutch children who visited emergency departments with burn injuries. Controls (n = 213) were a sample of the Dutch population of 0-4-year-old children without burn injuries. Odds ratios based on logistic regression (OR-LR) and 90 per cent confidence intervals (CI (90 per cent) were calculated for a number of putative risk factors. The risk of burns was higher for children with other than Dutch (e.g. Turkish) ethnicity (OR-LR = 5.6; CI (90 per cent) = 2.6-11.9). Children who lived in relatively small houses turned out to have a higher risk of burns (OR-LR = 2.5; CI(90 per cent) = 1.3-4.7). To our surprise, children belonging to lower socioeconomic classes were found to have a decreased risk of burns (OR-LR = 0.3; CI (90 per cent) = 0.1-0.6). Furthermore, among several manipulatable risk factors, the use of an oven window which gets hot while in use appeared to have an increased risk of burns (OR-LR = 2.1; CI(90 per cent) 1.3-3.5). The same holds for the storage of hot drinks in their original pots instead of in vacuum flasks (OR-LR = 2.0; CI (90 per cent) 1.2-3.1). Cooking on a gas stove was found to be another risk factor (OR-LR = 2.5; CI(90 per cent) 1.1-10.0).     

Burn epidemiology: a basis for burn prevention

An appreciation of the causes of burn injury is essential in order to direct burn prevention programs. Toward this goal, 1,564 patients treated at the UCI Burn Center were studied. There were 699 patients admitted acutely and 865 outpatients. The most common cause of thermal injury in both adults and children was scalding. In children scald burns accounted for 42% of the total number of children treated. In children under 4 years old scalds caused 75% of all burn injuries, most in the kitchen. Flammable liquids were responsible for the majority of the severe burns in the adult group (19% of acute admissions). Housefires, while accounting for only 5% of the adults treated, were responsible for 44% of the adult deaths. Continued public education in safety practices at home especially in the kitchen and bath, and with automobiles and outdoor stoves and fires is recommended, as well as planned escapes from homes and use of smoke detectors.     

A comparison of conservative versus early excision. Therapies in severely burned patients.

Early excision and grafting of small burn wounds is a generally accepted treatment. Early excision of burn injuries greater than 30% total body surface area (TBSA) in adults, however, has not been universally accepted. In this study, 85 patients whose ages ranged from 17 to 55 years with greater than 30% total body surface area (TBSA) burns were randomly assigned to either early excision or topical antimicrobial therapy and skin grafting after spontaneous eschar separation. Mortality from burns without inhalation injury was significantly decreased by early excision from 45% to 9% in patients who were 17 to 30 years of age (p less than 0.025). No differences in mortality could be demonstrated between therapies in adult patients older than 30 years of age or with a concomitant inhalation injury. Children (n = 259) with similar large burns treated by early excision showed a significant increase in mortality with increasing burn size and with concomitant inhalation injury (p less than 0.05). The mean length of hospital stay of survivors was less than one day per per cent of TBSA burn in both children and adults.     

An analysis of 1704 burn injuries in Hong Kong children

Over a 12-month period, 1704 children less than 15 years old with burn injuries seen in the accident and emergency departments of seven major regional hospitals in Hong Kong were analysed with respect to their epidemiological data. The age group with the highest risk for injury was 0-4 years (57 per cent) and with a maximum at 1-2 years of age. Boys showed a significantly higher incidence of burns than girls at any age. Ninety-three per cent of the accidents occurred at home and 92 per cent were scalds caused by hot water and other fluids. In the great majority of patients the total body area of burn did not exceed 5 per cent. Younger children had a higher incidence of burns involving the head, face and anterior trunk, 39 per cent of the 0-4 year age group required hospital admission. During the winter months, the children tended to suffer from deeper burns.     

The nursing home patient—a burn prone person. An epidemiological study

During the 6 years between 1980 and 1985, 39 nursing home patients were admitted to the Ilvidovre Burns Unit in Copenhagen with accidental burns. These patients accounted for 20 per cent of all burn patients above the age of 69 years admitted during this period. The median age of the patients was 80 years. Two-thirds of them suffered from burns of less than 15 per cent of their total body surface area. The mortality rate was 64 per cent. All patients were burned in single-person accidents, most often while sitting alone in their own living room, and smoking materials were involved in 85 per cent of the injuries. Senility, hemiplegia and other neurological diseases with tremor or paresis were frequently present in the victims.

Several preventive measures are proposed, including smoking under supervision, use of flame-resistant aprons of adequate size. Flame-resistant materials in chairs, etc.. and installation of smoke detectors in rooms where patients smoke. A possible relation between the marked incidence of these accidents during weekends or holidays, at a time when staff numbers are reduced in the nursing homes, is discussed.     

Work-related burns: a 6-year retrospective study

During the 6 years from July 1984 to May 1990, 193 patients (30.2 per cent of all patients) were admitted to our regional adult burn centre, for treatment of work-related burn injuries. The median age of patients was 32.5 years (range 18-64 per cent), and 94 per cent were males. Fifty-nine per cent of the patients came from metropolitan Toronto, and 40 per cent from rural Ontario. Most of the patients (97.3 per cent) were referred to the burn centre within 24 h of their injury. The most common aetiology was electrical injury (29.5 per cent), followed by flame (24.4 per cent), contact (10.4 per cent), flash (9.8 per cent), tar and asphalt (9.3 per cent), scald (7.8 per cent), chemical (5.1 per cent), steam (4.7 per cent) and grease (1 per cent). Within the electrical burn group, about one-half were flash burns, one-quarter were clothing fire injuries, and one-quarter were contact injuries. These occupational burns tended to be extensive injuries. The median body surface area (BSA) was 16.5 per cent, with a median full thickness (FT) component of 5.0 per cent. The average length of stay was 20.0 days. Inhalation injury requiring intubation occurred in 14.8 per cent of patients. Sepsis--confirmed by positive blood cultures--developed in 14 per cent of the patients, at an average time of 8.8 days postburn. Staphylococcus aureus was the commonest organism isolated from blood cultures. Pneumonia occurred in 6.3 per cent of patients. A total of 207 surgical procedures was performed on 113 of the 193 patients.(ABSTRACT TRUNCATED AT 250 WORDS)     

Acute electrical burns: a 10-year clinical experience

We have reviewed 113 cases of electrical burns treated at the Cook County Hospital Burn Center during the past 10 years. There were 3265 acute burn admissions during this period. the incidence of electrical burns being 3.5 per cent. Low-voltage electrical burns occurred in 82 of the 113 patients (73 per cent). These were caused mostly by household electricity supplies, occurred in children, and were preventable. Arc burns of the perioral region were allowed to heal spontaneously. The surgical management of other arc burns and flash burns was similar to that for most deep burn wounds. The incidence of high-voltage electrical injuries was 27 per cent in our series. Over 50 per cent of these injuries were not work-related. These tended to occur outside the home in young adult males and were also frequently preventable. None of these patients developed acute renal failure. Early surgical debridement of devitalized tissue with allografting, followed by delayed definitive wound closure or amputation prevented septic complications. Early fasciotomy appeared to have little effect on complete limb salvage. Limb loss continues to be the major factor contributing to the high morbidity associated with these injuries. All 113 patients survived. We attribute this to early transfer of patients to our Burn Unit, aggressive fluid resuscitation, continuous haemodynamic and metabolic support, and early surgical intervention.     

Paediatric burn injuries in New England, USA

The authors analysed a subset of data from the New England Regional Burn Program (NERBP) to describe the epidemiology of burn injuries for children aged from birth to 19 years in the six-state New England area of the USA. The subset of the NERBP data analysed pertained to residents of the six New England states who were admitted to hospital for the treatment of a burn injury sustained between 1 July 1978 and 30 June 1979. Analysis of the data revealed that 1128 (41 per cent) of the 2742 hospitalized burns identified occurred to persons between the ages of birth and 19 years, yielding an overall burn incidence rate of 30.7 burns per 100,000 person-years. Children aged from birth to 2 years sustained a higher burn rate, 96.7 burns per 100,000 child-years, than did children in any other age category. The burn rate for males was higher than the rate for females in each age category, as were the rates for black children compared to white children. Children in Massachusetts experienced the highest overall burn rate among the six New England states; the lowest rate occurred in New Hampshire. Overall, 63 per cent of the burns occurred in a residential setting. The most common activities related to burn injury were food preparation and food consumption, which accounted for 471 (42 per cent) of the burn injuries.     

Epidemiology of adults' and childrens' burns in a Turkish burn center

From 1 January 1979 to 1 January 1985, 4094 patients were treated for burn injury in our centre. Of these, 84.9 per cent were treated as outpatients and 617 (15.1 per cent) were hospitalized. Of the 617 patients, 56.7 per cent were under 15 years of age (birth to 6 years: 67.7 per cent; 7-15 years, 32.3 per cent) and 43.3 per cent were over 15 years. The causes of burns in the over 15 years group were: flame, 36.3 per cent; electrical, 28.0 per cent; scalding, 18.4 per cent; liquefied petroleum (LP) gas explosion, 11.0 per cent; and others, 6.3 per cent. The burn cases in the under 15 years group were: scalding, 58.0 per cent; flame, 24.6 per cent; electrical, 10.0 per cent; hot meals, 5.2 per cent; and others, 2.0 per cent. After being resuscitated, these patients were treated with systemic antibiotics, local chemotherapy and silver-nitrate-incorporated amniotic membrane. Despite all medical efforts, 217 (35.7 per cent) of the hospitalized patients died as a result of various complications. At the same time, 3477 patients were treated as outpatients: 72.0 per cent of these were under 15 years old (birth to 6 years, 82.9 per cent, 7-15 years, 18.8 per cent) and 28.0 per cent patients were over 15 years of age. The causes of burn injury in these patients were: hot liquids, 61.7 per cent; flame, 17.0 per cent; hot meals, 8.4 per cent; hot metal, 5.8 per cent; electrical, 3.6 per cent; and chemical, 1.7 per cent.     

Burn injuries in Lagos

Eighty-nine cases of burns admitted to the Lagos University Teaching Hospital during an 8-year period (1968–1975) have been studied. The age incidence ranged from 1 day to 54 years. Fifty cases (56·2 per cent) occurred in children below the age of 15 years. Thirty-nine (43·8 per cent) were adults, aged 15 years and above. Sixty-three cases (70·8 per cent) were domestic accidents. There was a mortality rate of 13·5 per cent. There was severe morbidity in the surviving cases, the average admission period in 73 cases being 37 days and the average total healing time in 57 cases being 54 days. The most troublesome late complications were contractures, hypertrophic or keloid scars and failure of repigmentation. Gram-negative bacteria accounted for 64 per cent of the incidence of wound sepsis.Health education has an important role to play in the prevention of burn accidents both in the home and in industry. In particular, it is suggested that cooking above floor level and closer supervision of children should reduce the incidence of domestic bums in younger children, while stricter factory inspection, with rigorous enforcement of industrial safety laws, should reduce the incidence of industrial burn accidents in the working adult population.     

Burn injuries in the Jeddah area of Saudi Arabia: a study of 319 cases

Three hundred and nineteen patients with different types of burns were studied at King Fahd Hospital, Jeddah, Saudi Arabia over a 2-year period (December, 1985 to December, 1987). Scalding was the most common cause (56.4 per cent) of burn injuries compared with 41.4 per cent of patients who sustained flame injury; 84.6 per cent of the thermal injuries occurred at home, with children (less than or equal to 18 years of age) being affected most frequently (61.8 per cent). The overall mortality was 9.4 per cent.     

Trends in hospital care of burns in Canada.

A review of burn admission patterns to Canadian hospitals from 1966 to 1991 from Statistics Canada data was prompted by a decrease to 125 burn patients admitted to Vancouver General Hospital in 1990 after a plateau at 180-195 per year for 6 years. The total number of fires from Fire Commissioner's data and data from 20 of the 27 Canadian burn units was analyzed. Canadian burn admissions decreased from 57 per 100,000 in 1966 to 23 per 100,000 in 1989. The admission rate is three times greater for children 0-4 years of age but has decreased parallel with the total. The number of fires decreased from 370 to 270 per 100,000 in the last decade. In 1981, 1986, and 1989 15 Canadian units treated a constant 15% share of hospitalized burns, while nine units reported a constant 7% of burn patients who also required ventilation for associated smoke inhalation injury. These trends forecast a 2%-4% decrease in hospitalized burns per capita per year.     

Characteristics of 1494 pediatric burn patients in Shanghai

Retrospective evaluation of admission criteria for paediatric electrical injuries

In the medical community, the practice of admitting all electrical burns for 24–48 h of observation, monitoring and laboratory evaluation is widespread. This retrospective review of paediatric electrical burns was conducted to determine which patients may safely be treated as outpatients.

Retrospective analysis of all paediatric burns admitted between 1980 and 1991 identified 35 patients with electrical injuries. Patients were divided into two groups for analysis: those burned by exposure to household voltages (120–240 V; n=26) and those exposed to high voltages, in excess of 1000 V (n=9).

The majority of household electrical injuries occurred secondary to contact with the household 120 V (21/26). Contact with an extremity accounted for the largest number of these injuries (18/26). The mouth was the second most frequent site of injury (7/26). Most of these patients (20/26) had < 1 per cent BSA burn. No patient in the household-voltage group had an arrythmia that required treatment, nor were there any identified examples of compartment syndrome or other vascular complications. Seven patients did require minimal skin grafting. No deaths occurred in either group.

The patients in the household-voltage group were significantly younger. High-voltage electrical injuries occurred in an older patient population and required more aggressive care and surgical intervention. This was evident at the time of initial evaluation. Based on these data, healthy children with small partial-thickness electrical burns and no initial evidence of cardiac or neurovascular injury do not appear to need hospital admission.
