Injuries, treatment, and impairment caused by different types of fireworks; results of a 10year multicenter retrospective cohort study

ObjectivesThe primary aim of this study was to evaluate the number of patients reported to a hospital with injuries from consumer fireworks in the months December-January in the past 10years, and to describe the association between the type of fireworks, injury pattern, treatment, and permanent impairment.MethodsA multicenter, retrospective, observational case series. Patients were selected from two hospitals in the Southwest Netherlands: a level 1 trauma center and a specialized burn center. All patients with any fireworks-related injuries treated between December 1 and January 31, during 2007 (December) to 2017 (January), were eligible for participation. The primary outcome was the number of patients with any type of injury caused by fireworks. The secondary outcome measures were patient and injury characteristics, treatment details, and whole person impairment (WPI). The percentage WPI expresses a patient's degree of permanent impairments as a result of fireworks-related injuries.ResultsOf the 297 eligible patients, 272 patients were included. From 2007 to 2017, between 21 and 40 patients were treated, and no clear increase or decrease was observed in the number of patients and in the number of patients per type of fireworks. Explosive fireworks mainly caused upper extremity (N=65; 68%) injuries, while rockets (N=24; 41%) and aerials (N=7; 41%) mainly affected the head/neck. Decorative fireworks predominantly resulted in burns (N=82; 68%), and explosive fireworks in soft tissue lacerations (N=24; 25%), fractures (N=16; 17%), and amputations (N=14; 15%). Patients injured by explosive and homemade fireworks were most often admitted to a hospital (respectively N=24; 36% and N=12; 80%), and resulted in the highest proportion undergoing surgical procedures (respectively N=22; 33% and N=7; 47%). WPI found in this study was between 0 to 95%, with a median of 0%. In 34 (14%) patients, the injuries resulted in a WPI of >= 1%, mostly as a result of explosive fireworks (N=18; 53%).ConclusionThis study found no increase or decrease in the number of patients treated in two specialized hospitals. Explosive and homemade fireworks could be considered as most dangerous, as they result into the most hospital admissions, surgical procedures, and into the most injuries with permanent impairment as a result.

Automated summary

The study found no significant increase or decrease in the number of patients treated in two specialized hospitals over the past 10 years. Explosive and homemade fireworks were considered the most dangerous, as they resulted in the highest number of hospital admissions, surgical procedures, and injuries with permanent impairment.
