National Electronic Injury Surveillance System-Work Supplement


The National Electronic Injury Surveillance System -- Work Supplement (NEISS-WORK) is an expansion of the Consumer Product Safety Commission's (CPSC) National Electronic Injury Surveillance System (NEISS), used to monitor consumer-product related injuries. NEISS-WORK collects data on all work-related nonfatal injuries and illness treated in U.S. hospital emergency departments, whether or not associated with consumer products. (NEISS data exclude work-related injuries and illnesses.) NEISS data are collected from a nationally representative sample of U.S. hospital emergency departments; NEISS-WORK uses a subsample of those emergency departments for its data collection.

Data Years Available: 
Mode of Collection: 
Electronic transmission of abstracted data.
Selected Content: 
NEISS-WORK collects demographic data, diagnosis, body part affected, ER disposition, information about the event or exposure, and the source of the illness or injury.
Population Covered: 
U.S. civilian non-institutionalized workers.

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. The NEISS-WORK data are collected at a subset of these hospitals and include very large inner-city hospitals with trauma centers, as well as large urban, suburban, rural, and children's hospitals. Trained onsite hospital coders abstract and code data from ED records for all treated cases that are classifiable as work-related. (Work is defined as doing work for pay or other compensation on the employers premises, or during transportation between locations as part of the job; doing agricultural production activities; and working as a volunteer for an organized group.) Data are weighted to produce national estimates.

Response Rates and Sample Size: 

NEISS collects data from a sample of 100 hospitals with 24 hour emergency department services. NEISS-WORK data are collected at 67 of these hospitals.
