WHAT'S KNOWN ON THIS SUBJECT: In 2001, an estimated 10 438 children were treated in US emergency departments for nonfatal choking on food. The foods most frequently associated with pediatric fatal choking are hot dogs, seeds, nuts, candy, and certain types of fruits and vegetables.WHAT THIS STUDY ADDS: From 2001 through 2009, an estimated annual average of 12 435 children ages 0 to 14 years were treated in US emergency departments for nonfatal choking on food; 0-to 4-year-olds accounted for 61.7% of episodes. Foods most frequently involved were candy, meat, bone, and fruits/vegetables. abstract OBJECTIVE: The objective of this study was to investigate the epidemiology of nonfatal choking on food among US children. METHODS:Using a nationally representative sample, nonfatal pediatric choking-related emergency department (ED) visits involving food for 2001 through 2009 were analyzed by using data from the National Electronic Injury Surveillance System-All Injury Program. Narratives abstracted from the medical record were reviewed to identify choking cases and the types of food involved.RESULTS: An estimated 111 914 (95% confidence interval: 83 975-139 854) children ages 0 to 14 years were treated in US hospital EDs from 2001 through 2009 for nonfatal food-related choking, yielding an average of 12 435 children annually and a rate of 20.4 (95% confidence interval: 15.4-25.3) visits per 100 000 population. The mean age of children treated for nonfatal food-related choking was 4.5 years. Children aged #1 year accounted for 37.8% of cases, and male children accounted for more than one-half (55. CONCLUSIONS: This is the first nationally representative study to focus solely on nonfatal pediatric food-related choking treated in US EDs over a multiyear period. Improved surveillance, food labeling and redesign, and public education are strategies that can help reduce pediatric choking on food. Pediatrics 2013;132:275-281 AUTHORS:
