Burn care is always progressing, but there is little epidemiological information giving a clear picture of the current number of treated burns in Sweden. This study was conducted to provide an update of patients admitted to hospital with burns in Sweden. Data were obtained for all patients who were admitted to hospitals with a primary or secondary diagnosis of burns (ICD-9/10 codes) from 1 January 1987 to 31 December 2004; 24,538 patients were found. Most of the patients were male (69%), giving a male:female ratio of 2.23:1. Children in the age-group 0-4 years old predominated, and accounted for 27% of the study material. The median length of stay was 3 days. Throughout the period 740 patients (3%) died of their burns. Significant reductions in mortality, incidence, and length of stay were seen during the study, which correlates well with other studies. However, most of the reductions were in the younger age-groups. Men accounted for the improved mortality, as female mortality did not change significantly. We think that the improvement in results among patients admitted to hospital after burns is a combination of preventive measures, improved treatment protocols, and an expanding strategy by which burned patients are treated as outpatients.
