  1. Safety Net Data Collection Strategies AHRQ User Liaison Program Washington, D.C. September 24, 2003 Lynn A.

  2. Estimating the Number of Uninsured • Estimates of demand based on state and local estimates of the number of uninsured • Most estimates come from household surveys that ask about health insurance coverage • Also used in combination with employer surveys that ask about health insurance coverage

  3. Estimating the Size of the Uninsured Populations at the Local Level • Do your own survey - To directly measure health insurance coverage and rates of uninsurance • Use existing available data to: • Develop proxy measures of uninsurance • Develop statistical model-based estimates

  4. Direct Measures: National Data • Three surveys provide state-level estimates of health insurance coverage. • Current Population Survey (CPS): Census • Medical Expenditure Panel (Employer) Survey – Insurance Component (MEPS-IC): Agency for Healthcare Research and Quality • State and Local Area Integrated Telephone Survey (SLAITS): National Center for Health Statistics

  5. Direct Measures: State Data • 37 States have developed and fielded their own state household survey to estimate levels of health insurance coverage • Many funded by the federal Health Resources Services and Administration State Planning Grant Program • Typically have larger sample size and some regional/county estimates of coverage

  6. Other National Surveys of Note • National Survey of America’s Families (NSAF): Urban Institute • Uninsurance estimates available for 13 states • Public use files available to states for analysis • Community Tracking Study: Center for Health System Change • Uninsurance estimates can be made for the 12 communities in the CTS sample

  7. Proxy Measures • Use an available measure to serve as a proxy for health insurance coverage • Example: self-pay variable from hospital administrative records to estimate local levels of uninsurance

  8. Model-Based Approach • Predicts health insurance coverage using one or more variables correlated with health insurance coverage • Example: correlation between state unemployment and uninsurance and applying this at local level

  9. National Model-Based Estimates • Small-Area Estimation • Census and AHRQ are both working on sophisticated models to provide state and local area estimates • CPS: Uninsurance • MEPS-IC: Employment offer and take up rates

  10. Overview of Approaches for Estimating Number of Uninsured At the Local Level

  11. Conclusions • Be knowledgeable and aware of different data sources available for your community • Use existing resources and data and build on existing state and local survey activities • Use multiple approaches to maximize information • Be flexible as new data become available
