HealthDay News — Pool chemical injuries led to an estimated 13,508 US emergency department visits during 2015 to 2017, and about one-third of these injuries occurred in children, according to research published in the May 17 issue of the US Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report.

Kayla L. Vanden Esschert, MPH, from the CDC in Atlanta, and colleagues estimated the annual number of US emergency department visits for pool chemical injuries using 2008 to 2017 data from the National Electronic Injury Surveillance System.

The researchers note that pool chemical injuries led to an estimated 13,508 US emergency department visits in 2015 to 2017; 36.4% occurred among patients aged <18 years. An estimated 5245 patients had their injury diagnosed as poisoning. Of the injuries, at least 56.3% occurred at a residence. About two-thirds of the injuries (64.5%) occurred from Memorial Day weekend through Labor Day. Patients were most often injured when inhaling chemical fumes or dust, when pool chemicals were not secured away from children, or when pool chemicals were added to the water just before patients entered.
