Purpose We evaluated the impact of Senate Bill 489 passed in May 2017, allowing the sale and use of fireworks in Iowa 1 June to 8 July and 10 December to 3 January, on hospital presentations for firework injuries in the state. To identify the public health implications of this law, we conducted a detailed subanalysis of hospital presentations to the two level I trauma centres.
Methods Hospital presentations for firework injuries from 1 June 2014 to 31 July 2019 were identified using the Iowa Hospital Admission database and registries and medical records of Iowa’s two level 1 trauma centres. Trauma centres’ data were reviewed to obtain demographics, injury information and hospital course. Prefirework and postfirework legalisation state data were compared using negative binomial regression analysis. Trauma centre data detailing injuries were compared using χ2 and Mann-Whitney U tests as appropriate.
Results Emergency department (ED) visits and hospital admissions for firework injuries increased in Iowa post-legalisation (B-estimate=0.598±0.073, p<0.001 and B-estimate=0.612±0.322, p=0.058, respectively). ED visits increased postlegalisation in July (73.6% vs 64.5%; p=0.008), reflecting an increase in paediatric admissions (81.8% vs 62.5%; p=0.006). Trauma centres’ data showed similar trends. The most common injury site across both study periods was the hands (48.5%), followed by the eyes (34.3%) and face (28.3%). Amputations increased from 0 prelegalisation to 16.2% postlegalisation.
Conclusion Firework legalisation led to an increase in the number of admissions and more severe injuries.
