  1. Household Survey Comparison Melissa Heinen, M.P.H. Margaret Warner, Ph.D. Lois Fingerhut, M.A. Montreal 2002

  2. Importance of Household Surveys • Not limited to medical records • Health professionals description • More detail about the event • Costs and resources

  3. National Household Injury Surveys Surveys reviewed • Canada – Canadian Community Health Survey (CCHS) and the National Population Health Survey (NPHS) • New Zealand – National Health Survey • Scotland – Scottish Health Survey • South Africa – South African Demographic and Health Survey • United States – National Health Interview Survey SOURCE: CDC/NCHS

  4. National Household Injury Surveys Items compared • Recall Period • Severity Threshold • Survey Methodology • Unit of Analysis • Injury Definitions • Survey Frequency • Probing / Screening Question SOURCE: CDC/NCHS

  5. Recall Period Items to consider • Memory decay • Telescoping • Heaping • Sample size / relative standard error SOURCE: CDC/NCHS

  6. Annual estimates of injury and poisoning conditions using different recall periods, NHIS 1997

  7. Recall Period SOURCE: CDC/NCHS

  8. Severity Threshold Measurements • Limitation in daily activities • Medical advice or treatment • Hospitalization status SOURCE: CDC/NCHS

  9. Severity Threshold Items to consider • Health insurance coverage • Subjective - health seeking behaviors • Accessibility of health professional (rural vs. urban) • Emergency department visits SOURCE: CDC/NCHS

  10. Severity Threshold SOURCE: CDC/NCHS

  11. Survey Methodology Items to consider • Non-response rates • Representation • Sensitive questions and non-reporting • Cost and resources SOURCE: CDC/NCHS

  12. Survey Methodology SOURCE: CDC/NCHS

  13. Unit of Analysis Items to consider • Comparability of numbers • Events (e.g., car crash) • Persons • Most severe • Most recent • Conditions (e.g., fractured leg) SOURCE: CDC/NCHS

  14. Unit of Analysis SOURCE: CDC/NCHS

  15. Injury Definitions Items to consider • Self report vs. coding of self reports (ICD coding) • Comparability SOURCE: CDC/NCHS

  16. Injury Definitions SOURCE: CDC/NCHS

  17. Survey Frequency Items to consider • Trends over time • Assess data • Sample size SOURCE: CDC/NCHS

  18. Survey Frequency SOURCE: CDC/NCHS

  19. Screener Question Items to consider • Length • Complexity • Embedded examples SOURCE: CDC/NCHS

  20. Screener Question SOURCE: CDC/NCHS

  21. Screener Question SOURCE: CDC/NCHS

  22. US Survey • Decrease injury rate • Cognitive testing -screening question • Length • Definitions • Severity

  23. Screener Question Proposed changes for US • During the past 3 months, that is since ##, did you have an injurywhere any part of your body was hurt, for example, with a broken bone, sprain, burn, wound, cut, bruise, or animal or insect bite? • During the past 3 months, how many times were you injured? • Did you talk to or see a medical professional about any of these injuries? • Of the # times that you were injured, how many of those times was the injury serious enough that you consulted a medical professional? SOURCE: CDC/NCHS

  24. Screener Question Proposed changes for US • During the past 3 months, that is since ##, were you poisoned by swallowing or breathing in a harmful substance such as bleach, carbon monoxide, or too many pills or drugs? (Do not include food poisoning, sun poisoning, or poison ivy rashes) • During the past 3 months, how many different times were poisoned? • Did you talk to or see a medical professional about any of these poisonings? • Of the # times that you werepoisoned, how many of those times was the poisoning serious enough that you consulted a medical professional? SOURCE: CDC/NCHS

  25. National Household Injury Surveys Additional items to consider • Placement of injury section within a larger survey • Length of survey • Sample selection • Definitions of injuries and poisonings • Narrative introduction to the section • Weighting of data • Respondent vs. Proxy SOURCE: CDC/NCHS

  26. National Household Injury Surveys Generic considerations • Continuous funding • Strong lobbying • Demonstrating usefulness of data SOURCE: CDC/NCHS

  28. Considerations • Should our goal be to compare our selves to each other to have better questions and survey methodology? • Is it a worthwhile goal to standardize questions? • Cause compatible with ICD? • Should health behaviors be a priority? • Is it even worth comparing numbers?
