  1. Improvements to the Collection of Injury and Poisoning Data in the National Health Interview Survey Patricia Barnes, M.A. Margaret Warner, Ph.D. Lois Fingerhut, M.A. Melissa Heinen, M.P.H. Montreal 2002 Centers for Disease Control and Prevention National Center for Health Statistics

  2. National Health Interview Survey • Face-to-face household survey • Nationally representative sample of civilian, non-institutionalized US population • Sample yields data on approx. 100,000 persons per year

  3. Timeline • 1957-96 Imbedded in questionnaire • 1997-99 Section on injury & poisoning • 2000-03 Combined inj & poi questions • 2004 “Unpacked” screen question

  4. Changes from the 1995 Survey to the 1997 Survey • Placement, phrasing and number of questions • Recall period • Severity threshold

  5. Data issues: 1997-1999 • Some questions not common to both injuries and poisonings • Injuries recorded as poisonings and poisonings recorded as injuries • High proportion in Other • No question on treatment location

  6. Changes: 1997-99 to 2000 Survey • Combined injury and poisoning questions • Added a question about medical advice or treatment • Revised categories for several questions

  7. Screener question:1997-99 and 2000-present 1997-99: DURING THE PAST THREE MONTHS, that is since {91 days before today date}, {were/was} {you/anyone in the family} injured seriously enough that {you/they} got medical advice or treatment? DURING THE PAST THREE … poisoned seriously enough that you …? 2000: DURING THE PAST THREE MONTHS, that is since {91 days before today date}, {were/was} {you/anyone in the family} injured or poisoned seriously enough that {you/they} got medical advice or treatment?

  8. Injury and poisoning

  9. Fixed Question Wording 1997-99: How many different times in the PAST 3 MONTHS {were/was} {you/subject’s name} injured seriously enough to seek medical advice or treatment? 2000: How many different times in the PAST 3 MONTHS did {you/subject’s name} seek medical advice because {you/subject’s name} were injured or poisoned?

  10. Finding Solutions to the Other Problems • Analyzed data • Held a teleconference with the interviewers in the field • Sent the injury and poisoning section through the Questionnaire Design Research Lab

  11. Unpacking the question 2000-03: DURING THE PAST THREE MONTHS, that is since {91 days before today date}, {were/was} {you/anyone in the family} injured or poisonedseriously enough that {you/they} got medical advice or treatment? • Three questions in one: • Were you injured? • Were you poisoned? • Did you seek medical advice?

  12. Proposed for 2004 During the past three months, that is since {January 2}, did you have aninjury where any part of your body was hurt, for example, with a broken bone, sprain, burn, wound, bruise, or animal or insect bite? During the past three months, that is since {January 2}, were you poisoned by swallowing or breathing in a harmful substance such as bleach, carbon monoxide, or too many pills or drugs? Did you talk to or see a medical professional about this {injury/poisoning}?

  13. What next? Stay tuned for whether our recommendations are implemented. See more information about the survey on the NHIS website
