Burns in patients over 60 years old: epidemiology and mortality.

Epidemiology and mortality among burn patients over age 60 years who were admitted to the Burn Centre of La Fé Hospital (Valencia, Spain) between 1 January 1988 and 1 January 1991 have been studied. A total of 443 patients (7.8 per cent of all presenting patients) were hospitalized during this 3-year period; of these, 69 (15.5 per cent) were over 60 years old. There were 40 females and 29 males (mean age, 72.2 years). Mean burn area was 21.6 per cent of total body surface, and the most commonly involved regions were the lower limbs (81 per cent). Fire flames were the most common cause of burns (65.2 per cent) and produced the most extensive lesions. Eight-five per cent of the accidents occurred at home, and winter was the season of highest incidence. Patient mortality was 33.3 per cent, the most common causes of which were hypovolaemic shock during the first 24 h and pneumonia in the later stages.     

An analysis of childhood burns in Kuwait.

A prospective study of 394 burned children (in-patients) up to the age of 12 years old was carried out for the period from January 1984 to December 1986. They were categorized into three age groups, the infants and toddlers 0-2 years, early childhood 3-6 years and late childhood 7-12 years. In the first two groups scalding was the predominant cause of injury, while in late childhood there were many more flame burns. Ninety-five per cent of the accidents occurred at home and the majority happened in the presence of parents. The presence of parents was not a deterrent to the accident but ensured speedy transport to the hospital. In our review 3 per cent of patients sustained more than 50 per cent BSA burns, there were 12 deaths with a mortality rate of 3 per cent. An intense campaign to make parents aware of the risk factors and their avoidance is required to reduce the number of burn accidents.     

Epidemiological pattern of adult burn injuries

An epidemiological survey of 411 patients over a period of five and a half years is analysed. There were no yearly trends but there was a slight increase in the number of female burns during the survey. There were 293 males, 71.3 per cent and 118 females, 28.7 per cent. The majority of the burns occurred in the younger age groups and reflect the cause of the injury. Approximately one-half of the injuries were burns of less than 10 per cent and three-quarters were of less than 20 per cent. The most extensive burns were caused by petrol and clothes fires. Predisposing conditions were present in 23.8 per cent of the patients, with alcohol abuse figuring prominently. Epilepsy was present in 2.7 per cent of the patients. The major predisposing conditions, causes and complications of the burn injuries are discussed. Burn infection occurred in 18.2 per cent of the patients and septicaemia in 3.5 per cent. There was a mortality rate of 8.3 per cent and the average length of hospital stay was 22.9 days. While these burns are mainly preventable it is difficult to see how this can be fully achieved.     

An epidemiological study of burn patients hospitalized in Valencia, Spain during 1989.

A retrospective study has been made of the patients hospitalized in the Burn Centre of La Fe Hospital in Valencia (Spain) during 1989. Of the 1825 patients seen during this period, 146 (8 per cent) were admitted to hospital. The mean patient age was 31.42 years, 68.5 per cent of the patients were male; 34.1 per cent were children under the age of 15 years and 15 per cent were over 60 years old. Fire was the most common cause of burns (50 per cent), and produced the most extensive lesions. Electrical current and firm contact with hot surfaces caused deeper burns. Thermal lesions were most frequently produced within the domestic environment. Burns caused by fire affected mainly the head and neck, scalding tended to involve the trunk and electrical current caused injury to the limbs. Half the hospital admissions were discharged within 15 days. Most of the lesions requiring hospital admission occurred during the winter months.     

Epidemiology of industrial burns in Brisbane

A retrospective epidemiological study of industrial burns admitted to the Royal Brisbane Hospital was conducted over a period of 7 years. A total of 182 patients were included in this survey--173 males (95 per cent) and 9 females (5 per cent). The proportion of industrial burns has decreased from 31.5 per cent to 18.5 per cent of total admissions to the burns unit over the past 10 years. Fifty per cent of the burns occurred in males less than 30 years old. The average age was 31 years. Two-thirds of the burns covered less than 10 per cent of the body and 84 per cent covered less than 20 per cent. While scalds were the commonest cause of industrial burns in our study (19.4 per cent), flame burns with clothing ignited caused the most extensive burns. Face and hands were the most common sites involved. Burns to these regions were mainly caused by flame and electrical burns. Eye burns comprised 5.5 per cent of the sample and were due to chemicals, gas explosions and electric flash. Twenty-six patients (14 per cent) suffered respiratory injury. Only one patient out of our series of 182 died. Progress has been made in industrial safety in the past few years but carelessness and human error still take their toll.     

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 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.     

Mortality of burn injuries in Jordan

Three hundred and ninety patients who died following fire burns and scalds between 1973 and 1982 were subjected to autopsy examination at the departments of Forensic Medicine in the Ministry of Health and Jordan University Hospital. Flame burns caused 82 per cent of the deaths. Most of the burn injuries occurred at home and most of the accidents may have been avoidable. Seventy-six per cent of the patients were children and young adults (0–29 years). Suicide caused 13·5 per cent of the deaths. The most common causes of death were septicaemia and hypovolaemia.     

Accidental falls using ladders leaning against a wall. A study of 266 cases in relation to the cause of the accident, sequelae and prevention

Falling accidents rank high on the list of industrial accidents in the building industry, accounting for 5.6 per cent (2) of allnotifiable cases. Studies were conducted into 266 falling accidents from lean-to-wall ladders, with age, trade, time of accident, cause of accident, and consequences being separately analysed. More than 50 per cent of all falling accidents occurred to workers while they were climbing ladders. Slight injuries accounted for 60.5 per cent, moderate injuries for 32.7 per cent, and severe injuries for 6.8 per cent. The falling depths of 79 per cent were between 0.3 m and 1.99 m. Lower extremities were primarily affected by distortion or dislocation, while upper extremities were more often injured by fractures. Non-compliance with safety rules was the most common single cause.     

Two years in burn care, an analysis of 12 423 cases

This is a retrospective study analysing 12 423 patients treated at our institution from 1 July 1988 to 30 June 1990. Burn incidence and mode of treatment were classified according to age and sex, as well as causative agent, place of the accident, length of treatment and outcome. 96.6 per cent of the patients were surgically treated, about 41 per cent of the patients were under 14 years of age. The most frequent cause of injury was related to meal preparation, with more than two-thirds of the accidents occurring at home. Only large or complicated burns (1094-8.8 per cent) were admitted, with 49 deaths occurring during this period. We conclude that children and younger adults are at greater risk of being burned and preventative measures should be oriented towards the prevention of such accidents.     

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)     

Chemical burns

This study reports the incidence and nature of chemical burns admitted to a large regional burns unit between 1 January 1981 and 31 December 1987. Of the 3251 patients admitted, 100 had sustained chemical burns; although they only comprised 3.1 per cent of the workload they accounted for 16.5 per cent of all industrial burning accidents. The victims were mainly male adults of working age. Alkaline materials caused 37 per cent of the accidents, 26 per cent attributable to caustic soda; acids caused a further 27 per cent, hydrofluoric acid accounting for half of these. The nature of the chemical was unknown in 13 per cent of the cases; this, together with the fact that workers were often unaware that they were using hazardous substances gives cause for concern. The methods for managing a diverse range of chemical burns are described.     

An analysis of burn mortality: a report from a Spanish regional burn centre

This paper reports an analysis of the mortality rates and related factors in our Burn Centre, based on 710 patients treated between 1985 and 1988. The average age of the patients was 23.8 years and the average burn size was 14 per cent of the body surface area. Burning injury affected mainly men (66 per cent), and their mortality rate was higher than that of women. The overall mortality rate was 6.6 per cent, the average age of the fatally injured patients being 54 years. We confirm that mortality in burned patients is closely related to: age (51 per cent of the patients were over 60 years of age); burn size (68 per cent of the patients had burns covering more than 30 per cent TBS); burn depth (57.4 per cent had full skin thickness burns); inhalation injury (present in 66 per cent of the fatally injured); and associated risk factors. The main cause of the burning injury was flames, chiefly from domestic accidents. The average survival time for the fatally injured patients was 10 days. Finally, our expected mortality followed a linear regression model, the LA50 for patients with only full skin thickness burns was 50 per cent.     

The problems and prevention of burns in developing countries

Burns are rapidly assuming greater importance as a cause of ill health in the developing nations. The major factors include gross ignorance of fire prevention, the quick spread of slums and the persistence of old traditional customs and beliefs. One hundred and forty-one new cases of burns were treated at the University of Calabar Teaching Hospital (UCTH) in a 2-year period from January 1984 to December 1985. A large proportion of the patients (91, or 64.5 per cent) were minor burns, while 40 (28.4 per cent) were serious burns, and 10 patients (7.1 per cent) suffered major burns. Thirteen patients (9.2 per cent) left hospital against medical advice or absconded without completing their treatment. There were six deaths (4.3 per cent), most of the deaths occurred in the major burns group. Lack of drugs and intravenous fluids, delay in bringing the patients to hospital, ignorance, superstition and old cultural and traditional beliefs contributed to the morbidity and mortality. Most of the burn injuries were caused by domestic accidents and were therefore preventable.     

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.     

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.     

All terrain vehicles (ATVs). A recreational gamble

Over the period September 1985 to July 1986, the authors reviewed 28 admissions to the Level I trauma center as a result of all-terrain vehicle (ATV) accidents. The patients ranged in age from 6 to 71 years, with nearly 33 per cent (9), under age 16. There were 22 (78.6%) male and 6 (21.4%) female patients. All suffered multiple abrasions, lacerations, and contusions. In addition, 21 (75%) patients had a fracture of some type. Eight (28.6%), had head injuries and 3 (10.7%) sustained spinal cord injuries with a permanent neurologic deficit. Intrathoracic injury occurred in 2 patients (7.1%) and intraabdominal injuries occurred in 1 (3.6%). Moreover, death occurred in 3 (10.7%). Simultaneously reviewed were admissions resulting from motor vehicle accidents (MVA) and motorcycle accidents (MCA) during the same period. By comparison, the death rates (DR), fracture rates (FR), and spinal cord lesions with deficit (SLR) were significantly higher in accidents with ATVs than with MVAs or MCAs. The death rates for ATVs, MVAs, and MCAs were 10.7 per cent, 4.6 per cent, and 1.2 per cent, respectively, with significance between the MCA and ATV groups, P = .0395. The FR were 75 per cent, 53 per cent, and 65 per cent, respectively, with P = .265. SLR was found in 10.7 per cent, 2.3 per cent, and 4.4 per cent of these same groups, with P = .0001. These data suggest that ATV riders are at a higher risk for sustaining fractures, significant spinal cord injuries, or death. ATVs clearly present a health hazard to riders of all ages.     

Pilot study of injured patients seen in the University of Port Harcourt Teaching Hospital, Nigeria

A 12-month pilot study of injured patients seen in the Emergency Department of the University of Port Harcourt Teaching Hospital was carried out. Trauma (28.8 per cent) was the main reason for emergency visits; 82.1 per cent of the patients were under 31 years of age. Domestic accidents were the commonest cause of trauma (42.5 per cent), followed by criminally motivated injuries (30.4 per cent), road traffic accidents (26.0 per cent), industrial (0.5 per cent) and other accidents (0.6 per cent). The overall mortality rate due to trauma was 5.4 per cent and within the period of study, trauma was the most common cause of deaths in hospital (10.1 per cent). Road traffic accidents were responsible for 67.9 per cent of these deaths, followed by criminally motivated injuries (16.1 per cent). Domestic, industrial and boat accidents caused 7.6 per cent, 5.4 per cent and 3.1 per cent deaths, respectively. Injury Severity Scores (ISS) among 419 patients showed a 100 per cent mortality for those with scores above 35. There were 48 prehospital, 19 emergency room and 14 in-hospital deaths among patients with an ISS below 35. The deaths resulted largely from delayed transportation of victims to the hospital and partly from inadequate emergency medical services. To reduce the current high rate of preventable deaths from injury, we recommend (i) ambulance services for early transportation of victims to the hospital and (ii) improved emergency medical care.     

Chemical burns: our 10-year experience.

A review of 173 patients with chemical burns admitted to our burn unit was carried out during the years 1976-85. Most burns were work related (83 per cent). The majority of patients were men aged 21-50 years (mean age = 29.6 years). The mean total body surface area involved was 3.6 per cent (range = 1-30 per cent). The mean length of stay in hospital was 6.3 days (range = 1-52 days). The extremities were involved in 68 per cent of the patients. The more common aetiological agents were bromine and its compounds (36 per cent), then acids (21 per cent), alkalis and organic substances (14.5 per cent each). The severest burns were caused by the inorganic substances. Delayed admission was most characteristic of the bromine and alkali burns. Complications included local infection (19 cases), systemic infection (two cases), inhalation injury (two cases), tissue necrosis (one case) and corneal erosion (one case). There were no deaths. Increased awareness of the hazardous potential of chemicals should help reduce the incidence of chemical burns.
