Burn injury in Bangladesh: electrical injury a major contributor.

Electrical injury is a major cause of burn injury and significant cause of mortality, morbidity and disability. To explore the proportional incidence of thermal and electrical burn injuries in Bangladesh, a population-based cross sectional survey was conducted between January and December 2003. Nationally representative data was collected from 171,366 rural and urban households, comprising of a total population of 819,429.The study was designed to describe the proportional incidence of thermal, electrical and chemical cause of burn in Bangladesh. Electrical injury constituted about one third of the total burn injuries. Among the total 1,999 injuries about 31% were due to electrical injuries, about 26% were due to flame, about 25% were due to hot liquid, over 16% by hot object, about 2% by chemical and less than 1% were due to explosives. The incidence of death rate was 3.97 per 100,000 populations per year. Thermal burn was found as the major cause of death due to burn injures and constituted 58% of the total deaths due to burn. Electrical injuries caused 42% of the deaths. It was estimated that more than 5,600 people die due to burn and electrical injuries every year in Bangladesh considering the incidence rate of 3.97 per 100,000 populations per year in the 150 million population. Electrical injury including lightning constitute about one third of the burn related mortality, morbidity and disabilities. Rural people and children are the more vulnerable group. Electrical injury needs to be included as a special component in a burn prevention strategy, particularly in rural Bangladesh.
