High-Powered Magnet Exposures in Children: A Multi-Center Cohort Study

Area of Science:

• Pediatric Health
• Consumer Product Safety
• Medical Device Epidemiology

Background:

• High-powered magnets were removed from the US market in 2012 but returned in 2016 following federal court decisions.
• The return of these magnets has been associated with an increase in exposures, yet outcome data remain limited.
• Previous Consumer Product Safety Commission (CPSC) protections were overturned due to cited imprecise data.

Purpose of the Study:

• To describe the epidemiology of high-powered magnet exposures in children seeking medical care.
• To analyze the outcomes associated with these exposures following the magnets' reintroduction to the market.
• To provide data on pediatric magnet ingestions and insertions.

Main Methods:

• A multicenter, retrospective cohort study was conducted.
• Data were collected from 25 children's hospitals across the United States.
• The study included patients aged 0 to 21 years with confirmed high-powered magnet exposure between 2017 and 2019.

Main Results:

• 596 patients with high-powered magnet exposures were identified, with 95% being under 14 years old.
• Magnet ingestion was the most common exposure (96.3%), leading to life-threatening morbidity in 9.6% of cases.
• Nearly half of patients required endoscopy or surgery (46.3%), and over half required hospitalization (55.7%).

Conclusions:

• Despite being marketed for individuals over 14, high-powered magnets cause significant morbidity in children.
• These exposures necessitate a high rate of invasive interventions and hospitalizations.
• The study highlights the ongoing risks associated with high-powered magnets in the pediatric population.
