Epidemiology of outpatient burns in Tehran: an analysis of 4813 cases

This study aims to demonstrate the epidemiologic characteristics of outpatient burn injuries in Tehran. This cross-sectional study was performed over a 1-year period in a referral burn centre in Tehran and included all outpatient burns. The required data were recorded by two trained physicians. Of the 4813 studied patients, including 293 infants, 2901 patients (60%) were male (P<0.001). The mean age of the adult patients was 31.3+/-18.3 years, while for infants it was 10.68+/-2.27 months. In all age groups and both genders, scalding was the most common aetiology. Majority of the burns were non-intentional (n=4808) and 70.5% of the injuries occurred at home. Housewives consisted of 24% of the burn patients. With respect to the site of burn, multiple injuries were the most frequent (53%) followed by upper extremities (37%). Most of the burns (96%) were partial thickness. Significant association was present between the aetiology and depth of burn (P<0.001). The mean affected total body surface area (TBSA) was 3.16+/-2.92% and there was significant association between burnt TBSA and the mechanism of injury (P<0.001). In conclusion, it seems that women aged 21-30 years and children younger than 10 years are at greater risk of these injuries and therefore should be the target for preventive strategies.
