  1. What Role Does SCHIP Play in the Patchwork Insurance System for Children? Andrew W. Dick PhD1 R. Andrew Allison PhD2 Peter G.

  2. Background - SCHIP State Children’s Health Insurance Program • BBA of 1997 established SCHIP, providing $40 billion for block grants to states (10 years) • Provides a mechanism for insuring children who fall in the gap between Medicaid and private insurance • Provides wide latitude for states in designing and changing enrollment and eligibility policies

  3. Study Objectives Determine how SCHIP fits into the patchwork system • Describe SCHIP-enrollment patterns • Duration of enrollment, insurance prior to and following enrollment, and their relationships. • Describe differences in these patterns by subgroups • Race/ethnicity, special health care needs, poverty • Relationship between enrollment patterns and health systems access and use measures

  4. SCHIP Policies in Three States • Kansas (HealthWave, 1999) • 2001 enrollment = 34,241 • Florida (Healthy Kids, 1990) • 2001 enrollment = 298,705 • New York (Child Health Plus, 1991) • 2001 enrollment = 590,000 (18% of US)

  5. SCHIP Policies in Three States

  6. Study Design • Surveys: telephone interviews at • T1 : pre-SCHIP access/use, baseline SES • 3 to 6 months after enrollment about year before enrollment • T2 : during-SCHIP access/use, post-SCHIP insurance status • 13 to 16 months after enrollment about year after enrollment • Administrative data: monthly SCHIP-enrollment status and (KS and FL only) Medicaid enrollment status

  7. Subjects: (New Enrollees 7/00-3/01) • New York: • 2,290 completed T1 and T2 surveys • Florida: • 944 completed T1 and T2 surveys • Kansas: • 434 completed T1 and T2 surveys

  8. Measures • Access: Usual Source of Care (USC), type of USC, Unmet needs • Use of care: Any, preventive, acute, specialty • Pre-SCHIP Insurance: • Within the 12 months prior to SCHIP -- Medicaid, private • Ever insured prior to the 12 months before SCHIP enrollment • Never insured • Post-SCHIP Insurance: • Insurance status in month 13 -- Public (SCHIP, Medicaid), private, uninsured • Insurance Status immediately following SCHIP-disenrollment -- Public, private, uninsured

  9. Analyses: Enrollment Duration • Kaplan-Meier survivor functions • by prior insurance and by NY regions (9/11) • Multivariate logistic regressions • probability of surviving at least 10 months • probability of surviving at least 13 months given at least 10 months

  10. Analyses: Insurance Disposition • Multivariate multinomial logistic regression • Estimate insurance status immediately following SCHIP-disenrollment • Multivariate controls include: • SES • prior insurance • pre-SCHIP access and use • during-SCHIP access and use (when appropriate)

  11. Length of SCHIP Enrollment • By race • By income • By prior insurance • By CSHCN status • By use

  12. Insurance Status Following Disenrollment from SCHIP By duration and • By prior insurance • By CSHCN status • By access and use during SCHIP

  13. Conclusions - Recertification • Confirms and strengthens previous finding about recertification • No difference in exit rates in Florida (quantity or correlates) around recertification • Large increases in disenrollment rates around recertification in New York and Kansas • Disenrollment process differed in months 1 - 9 and 10 - 12 by income, CSHCN status and prior use • Very large differences by NY regions, consistent with 9/11 change.

  14. Conclusions – Length of Enrollment • No notable differences in length of enrollment by prior insurance status • No evidence of racial/ethnic differences except for blacks in Florida

  15. Conclusions – Insurance Status Following SCHIP Disenrollment • Children who disenrolled around active recertification were much more likely to become uninsured. • Pre-SCHIP insurance is a predictor of post-SCHIP insurance • SCHIP is not serving as a pathway to private insurance • No evidence that during SCHIP use and unmet needs affect insurance status after disenrollment.

  16. Conclusions - CSHCN • CSHCN could be at greater risk of losing insurance. • disenroll more quickly (esp. around recert.). • more likely to become uninsured after SCHIP.

  17. Limitations Limitations: • Internal Validity • Self-report • large conflicts between self-reported SCHIP-enrollment status and administrative data • Longitudinal survey response rates • KS: 35 % (T1 = 60%, T2=58%) • FL: 30 % (T1 = 60%, T2=50%) • NY: 55% (T1 = 64%, T2=87%) • External Validity: • Three states that may not be representative of many other states.
