National Electronic Injury Surveillance System

Description: 

CThe National Electronic Injury Surveillance System (NEISS) is an injury surveillance and follow-back system. Its primary purpose is to provide timely data on consumer product-related injuries occurring in the U.S. NEISS collects injury data from a nationally representative sample of 100 U.S. hospital emergency departments selected from all 5,300+ U.S. hospitals with emergency departments. From these data, national estimates of the numbers of injuries associated with (not necessarily caused by) specific consumer products are made. This information is used by the Consumer Product Safety Commission (CPSC) in determining the need for product recalls, public awareness campaigns, and product safety standards.

Data Years Available: 
1978-present
Periodicity: 
Annual
Mode of Collection: 
Electronic transmission of abstracted data.
Selected Content: 
NEISS collects demographic data, cause/mechanism of injury, locale where injury occurred and product involved.
Population Covered: 
N/A
Methodology: 
NEISS hospitals are a stratified probability sample of all U.S. hospitals that have at least 6 beds and provide 24 hour emergency department (ED) services. Five strata are included, four representing hospitals of different sizes, and the fifth representing children's hospitals. At each NEISS hospital, an NEISS hospital coordinator reviews all ED records daily; selects those that meet the criteria for inclusion in NEISS; abstracts pertinent data from the selected records; and transcribes the data in coded form to a NEISS coding sheet. Coded data and a narrative are transmitted electronically to the NEISS program where quality assurance coders review and complete the coding. Data are weighted to produce national estimates. Follow-back investigations to obtain more information about the likely causes of the incident are conducted for certain incidents through telephone and on-site interviews with the patient or patient's relative.
Response Rates and Sample Size: 
NEISS collected data from a sample of 100 hospitals with 24 hour emergency department services.
