  2. Outline • Purpose of NEISS-AIP • Sample Design • Data Elements • Quality Assurance Methods • Data Reporting

  3. National Electronic Injury Surveillance System (NEISS) • Operated by the U.S. Consumer Product Safety Commission (CPSC), Started October, 1978 • Monitor consumer product-related injuries • Nationally representative sample of 99 U.S. hospitals with > 6 beds and an ED • First time, injury-related visits

  4. Components of NEISS • Ongoing ED surveillance • Special studies • Follow-up investigations

  5. Ongoing ED Surveillance • Sampling frame updated every 10 years (last update 1997) • Captures 330,000 consumer product-related injuries annually • Timely access to data • Core data elements (age, sex, race/ethnicity of patient, two-product codes, primary body part affected, principal diagnosis, locale of injury incident, ED discharge disposition, narrative)

  6. 99 NEISS Hospitals Claremont, NH Pittsfield, MA Brooklyn, NY Patchogue, NY Staten Island, NY Bridgeton, NJ Lanham, MD Rockville, MD Very Large Hospitals Large Hospitals Medium Hospitals Santurce, PR Small Hospitals Children’s Hospitals Data Source: U.S. CPSC

  8. NEISS All Injury Program • Started July, 2000 • Nationally representative subsample of 66 NEISS hospitals with > 6 beds and an ED • First time, injury-related visits

  9. NEISS All Injury Program • Approx. 500,000 cases per year (@ $4.00 USD per case) • Extensive training and quality assurance program with both automated and visual edits • Data on mechanism and intent of injury • Data available to public annually in the late summer of following year

  10. NEISS All Injury Program Cause-of-Injury Data Elements • Mechanism (precipitating & immediate) • 22 categories (ICECI short version) • For transport (traffic-relatedness) • For MV-occupant (occupant status) • Intent of injury • Assault, suspected and confirmed (victim-offender relationship, context of assault) • Self-harm, suspected and confirmed • Unintentional/undetermined

  11. Public Access of NEISS_AIP Data? • Web-based Injury Statistics Query and Reporting System (WISQARS) • NEISS AIP analysis files available through the Inter-University Consortium for Political and Social Research (ICPSR) at the University of Michigan • CDC fact sheets on the internet, MMWR, peer-reviewed articles, state profiles
