National Electronic Injury Surveillance System-All Injury Program
The National Electronic Injury Surveillance System -- All Injury Program (NEISS-AIP) 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-AIP expands the CPSC's definition of reportable injuries to include all nonfatal injuries and poisonings treated in U.S. hospital emergency departments, whether or not associated with consumer products. NEISS collects injury data from a nationally representative sample of U.S. hospital emergency departments; NEISS-AIP uses a subsample of those emergency departments for its data collection.
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-AIP 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 for injury-related cases from ED records. Coded data and a narrative are transmitted electronically to the NEISS-AIP program where quality assurance coders review and complete the coding. Data are weighted to produce national estimates.
NEISS collects data from a sample of 100 hospitals with 24 hour emergency department services. NEISS-AIP data are collected at 66 of these hospitals. About 500,000 injuries are reported annually.
