ObjectivesTo determine the trend in incidence of pediatric magnet ingestions at 2 large Canadian tertiary pediatric hospitals after reintroduction of magnets to the US marketplace and to evaluate morbidity and mortality related to these ingestions.MethodsThis was a retrospective study performed in 2 tertiary care pediatric hospitals between 2004 and 2019. We reviewed the charts of all children who presented with a foreign body ingestion and included those with reported magnet ingestion. We characterized all events and compared the incidence rate before and after the US ban was overturned in 2016. Descriptive statistics were used to summarize our results. Incidence rate ratio was calculated using the total number of magnet ingestion cases and total emergency department visits normalized to 100,000 emergency department visits/year.ResultsWe screened a total of 6586 ingestions and identified 192 patients with magnet ingestions. The period after the mandatory recall was compared with the period after the US ban revocation yielding an incidence rate ratio of 0.76 for all magnet ingestions ( P = 0.15) and 0.73 ( P = 0.34) for multiple magnet ingestions. There was, however, a graphical upward trend that immediately followed the US ban revocation. Sixty-nine patients (36%) were admitted to the hospital and 45 (23%) required a procedure to remove the magnet ingested. No deaths occurred.ConclusionsOur findings suggest that the overturning of the US ban did not lead to a significant increase in the incidence of rare earth magnet ingestion in 2 large tertiary pediatric hospitals in Canada despite noting a trend upwards.Copyright © 2024 Wolters Kluwer Health, Inc.
