  6. The Impact of State Children’s Health Insurance Program (SCHIP) Expansion on Health Insurance Coverage in Hawai`i Gerard Russo, Ph.D. Sang-Hyop Lee, Ph.D. Lawrence Nitz, Ph.D. Thamana Lekprichakul, Ph.D. Abdul Jabbar, Ph.D. Candidate University of Hawai`i at Mānoa Kathleen Baker, Ph.D., Hawaii Department of Health Hawaii HRSA SPG Technical Workshop VI 17 September 2004 This research is funded in part through a U.S. Health Resources and Services Administration, State Planning Grant to the Hawaii State Department of Health. Sub-Contract Research Corporation of the University of Hawaii. Research conducted by the University of Hawaii, Social Science Research Institute in collaboration with the Hawaii State Department of Health, Hawaii Institute for Public Affairs: Hawaii Uninsured Project and the Hawaii Health Information Corporation.

  7. Research Objective: Purpose of this study is two-fold. • First, to assess the impact of the initial SCHIP expansion which occurred in Hawaii July 1, 2000 and extended free public insurance coverage to all children aged 0-18 years residing in households with incomes not greater than 200% of the Hawaii specific federal poverty level (FPL). • Second, to predict take-up of public coverage and crowd-out of private insurance which may occur under a proposed expansion of eligibility to children aged 0-18 years residing in households with incomes between 201% and 300% of the federal poverty level (FPL). Preliminary results. Revised September 2004. Subject to further revision.

  8. Hawai`i Title XXI Program: SCHIP • July 2000 SCHIP Hawaii children aged 0 to 18 years 200% of the FPL effective. • Hawaii SCHIP is implemented as a Medicaid/QUEST expansion. • The Hawaii Medicaid Program is implemented as a Managed Care & Managed Competition Program under the acronym QUEST: 1115 Waiver Demonstration. Preliminary results. Revised September 2004. Subject to further revision.

  9. SCHIP Federal Medical Assistance Percentage: Hawaii 2000-2005 Preliminary results. Revised September 2004. Subject to further revision.

  10. Hawai`i SCHIP Program Eligibility by Age and Federal Poverty Level Preliminary results. Revised September 2004. Subject to further revision.

  11. Population Studied • This study analyzes the insurance coverage of Hawaii residents aged 0-18 years residing in households with incomes between 0% and 300% of the Hawaii specific federal poverty guidelines as published by the U.S. Department of Health and Human Services. • Weighted population estimates are produced using the Hawaii Health Survey 1998-2002 and the Hawaii sample of Current Population Survey 1998-2003. Preliminary results. Revised September 2004. Subject to further revision.

  12. Population Studied (continued) • Three groups are analyzed • Children eligible for free public insurance throughout the period (“The Control Group”). • Children who began the period ineligible and became eligible in July 2000 (“The Treatment Group”). • Children who were ineligible throughout the period. This is the target group for future expansion. Preliminary results. Revised September 2004. Subject to further revision.

  15. Method of Analyzing SCHIPExpansion Using the Hawaii Health Survey and Current Population Survey • Natural Experiment Based on July 1, 2000 SCHIP Expansion • Pre-Expansion Survey Years: Before July 1, 2000 • HHS 1998,1999,2000 thru June • CPS 1998,1999,2000 • Post-Expansion Survey Years: After July 1, 2000 • HHS 2000 after July, 2001, 2002 • CPS 2002, 2003 • Difference-in-Differences Approach Preliminary results. Revised September 2004. Subject to further revision.

  16. Data is Split Four Ways • 1.Treatment Group Before SCHIP • 2.Treatment Group After SCHIP • 3.Control Group Before SCHIP • 4.Control Group After SCHIP • Pooled Regression Model • Dummy Variables Pick Up Differences Preliminary results. Revised September 2004. Subject to further revision.

  17. Econometric Model: Multinomial Logit • Predictor Variables • Age • Sex • Income (FPL) • County of Residence • Race/Ethnicity • Health Status • Adult Employment Status • Adult Educational Attainment • Number of Children • Multinomial Logit to Estimate the Probability of Coverage • Three Categories • Uninsured • Private Insurance & Other • Medicaid QUEST SCHIP Preliminary results.

  23. POLICY SCENARIO:SCHIP EXPANSION Expand the eligibility requirement for the State Children’s Health Insurance Program for children aged 0-18 years from an upper limit of 200% to 300% of the Federal Poverty Level. This research is funded in part through a U.S. Health Resources and Services Administration, State Planning Grant to the Hawaii State Department of Health. Sub-Contract Research Corporation of the University of Hawaii. Research conducted by the University of Hawaii, Social Science Research Institute in collaboration with the Hawaii State Department of Health, Hawaii Institute for Public Affairs: Hawaii Uninsured Project and the Hawaii Health Information Corporation.

  24. Estimated Impact of SCHIP Expansion from an Upper Limit Eligibility of 200% FPL to 300% FPL Preliminary results. Revised September 2004. Subject to further revision.

  25. Principle Findings • Based on the CPS estimates, the initial SCHIP implementation of July 1, 2000, which brought public insurance eligibility to 200% FPL, crowded-out private insurance at the rate of 2.4 children for every one child previously uninsured. • The proposed further expansion to 300% is projected enroll 6440 additional children. Of these approximately 1870 would have been previously uninsured, while 4570 would be drawn from privately insured families. Preliminary results. Revised September 2004. Subject to further revision.

  26. Conclusion • Because of a number of factors, including Hawaii’s Pre-paid Health Care Act of 1974, which mandates private sector employment-based coverage, middle-class families are typically well insured. Of the approximately 65,000 children aged 0-18 years residing in families with incomes between 201% and 300% of the FPL, only 2000-6000 are without health insurance coverage. As a result, a generous public expansion which takes all comers up to 300% FPL is likely to yield a large number of privately insured along with the uninsured. Preliminary results. Revised September 2004. Subject to further revision.

  27. Policy Implications • A Hawaii SCHIP expansion to 300% of the FPL will result in crowd-out of private insurance on a 2.4-to-1 basis for every newly insured child. • Whether viewed from the broad federal perspective or the narrow state budgetary perspective, such an expansion would generate high public expenditures per newly insured child and should therefore be pursued with caution. • A successful and sustainable expansion of eligibility criteria must be accompanied by safeguards against excessive private insurance crowd-out. Preliminary results. Revised September 2004. Subject to further revision.

  28. Limitations • Program participation and crowd-out are estimated imprecisely. • Estimates only cover SCHIP through 2002. • Unable to estimate the extent to which SCHIP prevents Medicaid spend-down. • HHS and CPS subject to Medicaid Under Count. Preliminary results. Revised September 2004. Subject to further revision.
