title: The health and economic impact of fireworks-related injuries in Iran: a household survey following the New Year's Festival in Tehran.
abstract: BACKGROUND
  Fireworks are used worldwide as a part of national and cultural celebrations. Personal use of fireworks is associated with serious injuries. The "Last Wednesday Eve Festival" is celebrated on the evening before the last wednesday of the Persian calendar year. In recent years, fireworks have been widely used during the festival, which has resulted in injuries. The aim of this study was to determine the incidence and risk factors of fireworks-related injuries associated with the Last Wednesday Eve Festival, in Tehran, Iran.
  
  
  METHODS
  A household survey of residents of greater Tehran, using a random cluster sampling design was performed. Number of fireworks-related injuries, expenditures for fireworks and medical treatment of fireworks-related injuries, length of hospital stay for treatment of these injuries and the personal property damage was gathered.
  
  
  RESULTS
  Interviews were conducted of 2475 households in greater Tehran. At least one member of 19.8% of these households had used fireworks during the 2007 Last Wednesday Eve Festival. Fireworks-related injuries were more common among households whose members had used homemade fireworks than among households whose members had used only commercially made fireworks (OR=16.5, 95% CI: 5.7-47.5). Forty-five households reported that they had sustained personal property damage caused by fireworks during the festival, costing a mean of US$ 36.60. Households with at least one injured member spent a mean of US$ 441.90 for medical care and a mean of US$ 70.80 for other expenses related to seeking medical care. The overall incidence of fireworks-related injury among household members was 0.2% (95% CI: 0.1-0.3%). Fireworks-related injury incidence was highest in the 10-19 age group. The total estimated number of fireworks-related injuries in Tehran during the 2007 Last Wednesday Eve Festival was approximately 17,000. Among the 20 injured individuals, 4 persons (20.0%) were hospitalised for a mean of 2.8 days.
  
  
  CONCLUSIONS
  The personal use of fireworks in Iran is associated with serious injuries and non-trivial economic costs. This study is the first to describe the incidence and economic costs of fireworks-related injuries in a major city in Iran using a population-based survey. To prevent these injuries, individuals should attend public fireworks displays conducted by professionals rather than engage in personal use of fireworks.
