The liberalization of fireworks legislation and its effects on firework-related injuries in West Virginia

摘要

BACKGROUND:Fifteen states, including West Virginia, have liberalized their laws concerning fireworks possession and sale. Effective June 1, 2016, House Bill 2852 enabled all Class C fireworks to be sold within the state. The effects of this policy on fireworks-related injuries requiring immediate medical care are unknown. The purpose of this study was to determine whether this policy may have affected the fireworks-related injury rate and/or injury severity.METHODS:Data were collected from the electronic medical records of patients treated by West Virginia University Medicine between June 1, 2015-May 31, 2017. The pre and post law periods were defined as June 1, 2015-May 31, 2016 and June 1, 2016-May 31, 2017, respectively. Fireworks-related injuries were identified via International Classification of Disease Clinical Modification codes and by free text searches of the electronic medical records. The rate of injuries pre and post-legislation were compared by Exact Poisson Regression, while demographic characteristics and injury severity were compared via Fisher's Exact tests.RESULTS:56 individuals were treated for fireworks-related injuries during the study period. The majority of patients were over 25?years of age (64%) and male (77%). Most of the injuries occurred within 7?days of a celebrated U.S. holiday (64%), and 28% were severe in nature. Age, sex, and injury severity did not significantly differ pre and post law passage. The injury rate per 100,000 patients was 39% higher after the law was enacted (p?=?0.3475; incidence rate ratio 1.39, 95% Confidence Interval 0.74, 2.68).CONCLUSION:The law increasing access to Class C fireworks may have affected the injury rate, but not injury severity among treated patients. Effective, evidence-based, public health interventions applicable to all age groups may be warranted particularly around national holidays. This study may inform other states looking to amend their legislation.
