The National Electronic Injury Surveillance System (NEISS) is a surveillance and follow-up system that collects data on consumer product-related injuries occurring in the United States used by the Consumer Product Safety Commission (CPSC) to produce nationwide estimates of product-related injuries. The dataset comprises a nationally representative probability sample of hospitals in the United States and its territories, which report patient information for every emergency department (ED) visit associated with a consumer product or a poisoning to a child younger than five years of age. NEISS includes 100 hospitals that have at least six inpatient beds and a 24-hour ED, stratified based on ED size (determined by the annual number of ED visits reported by each hospital) and geographic location, as well as a stratum of children’s hospitals.

Each NEISS dataset contains a complete year of data spanning treatment dates January 1 – December 31, and includes the patient’s age, race, ethnicity, injury diagnosis, affected body parts, incident locale, and a brief narrative describing NEISS incident scenarios. Each case is assigned a weight to provide nationally representative estimates that resulted in an ED discharge. NEISS data are de-identified and publicly available.
