Population-based study of emergency department admissions and deaths from injuries in Barcelona, Spain: incidence, causes and severity.
The aim of this study was to estimate the incidence of morbidity and mortality due to injuries in the population over the age of 14 years in Barcelona, Spain. Injury distribution according to sex, age, external cause, place of occurrence of the injury and severity was also obtained. A one-year survey was conducted in the emergency departments of the six main hospitals in Barcelona, based on a multistage sampling. Information was collected prospectively in emergency services by specially trained non-staff interviewers. Mortality data were drawn from death certificates. The incidence rate was 74.7 injury cases per 1,000 person-years over 14 years of age, higher in males than in females. Injury rates were highest in the youngest age-group and progressively lower until people over 75 years of age. Main external causes of injury were falls, being struck or caught by objects, and traffic-related injuries. The leading specific causes of injury mortality were traffic injuries, suicides and poisonings. While the overall admission incidence was 3.34 cases per 1,000 inhabitants, the proportion of hospitalized cases was 45.0 per 1,000 injury cases admitted to emergency rooms, higher for females, for traffic injuries and in the elderly population. Ninety-six percent of injury cases had an ISS value of 8 or less, mean ISS being highest for traffic injuries and falls. Injury morbidity and mortality amongst residents of Barcelona follow sex, age and cause of injury patterns which are, overall, comparable to those observed in other industrialized countries, suggesting that similar etiologic factors might be operating in those areas. The results should enable the orientation of injury prevention policies in the urban environment targeted on the young and the elderly population.
