Background - SCHIP State Children’s Health Insurance Program • $40 billion, block grants to states (10 years) • Low-income children not eligible for Medicaid • SCHIP in New York State (2002) • Acts like a separate program (not Medicaid) • Administered through MCOs • Enrollment = 600,000 (18% of US) • Important to measure how well SCHIP works • For children in general and those with chronic conditions
Children with Asthma • Most common chronic physical child condition • 5-10% of children • More prevalent and problematic among the poor • High utilization and costs (visits, medications) • NHLBI guidelines for care exist • Preventive visits and meds • Prior studies: Problems with access if no coverage
Study Objectives • Describe characteristics of SCHIP enrollees with asthma • Prevalence in SCHIP • Severity of asthma • Measure effect of SCHIP on children with asthma • Utilization of services • Quality of care • Asthma outcomes
Study Design • Pre-Post telephone interviews of parents of SCHIP enrollees Interview Measurement Period T1 Soon after enrollment Year before SCHIP T2 12 months later 1st year during SCHIP • Comparison group who enrolled 1 year later • To test for secular trends (few trends found)
Subjects:Main Study- All Children • Stratified sample of children by: • Region: NYC, NYC environs, upstate urban, rural • Age: 0-5 yr, 6-11 yr, 12-18 yr • Race/ethnicity: White NH, Black NH, Hispanic • 2,644 first-time SCHIP enrollees • Enrolled between Nov 2000 and March 2001 • 2,290 (87%) completed interviews 1 year later (2001-2002) • 400 Comparison group subjects • Random sample
Asthma Screener Methods* • During past year, did MD say child had asthma or • Did child have any of the following apart from a cold? • Wheezing or whistling in chest • Chest sounding wheezy during or after exercise • Waking from sleep because of cough or wheeze • Wheezing severe enough to limit speech *Questions adapted from NHLBI guidelines – Child had asthma if YES to either #1 or #2

Questions to IdentifyAsthma Severity* - Frequency of asthma symptoms - Limitations of activities - Nighttime awakening due to asthma “Mild” “Moderate to severe” *Questions adapted from NHLBI guidelines
Questions to IdentifyAsthma Severity – at T1 - Frequency of asthma symptoms - Limitations of activities - Nighttime awakening due to asthma “Mild ” “Moderate to Severe” 334 202 (60%) 132 (40%)
Measures and Analyses Measures • Access: Usual Source of Care (USC), Unmet needs • Use of care: Preventive, acute, specialty • Quality measures: % of visits to USC, parent ratings of quality • Asthma-specific: Use of care, severity, quality Analyses • Bivariate and multivariate • Comparing measures: “pre-SCHIP” vs “during SCHIP” • Secular trends: Study group vs Comparison group (few found) • Results weighted using STATA to account for complex sampling design
Results: Demographics of Children with Asthma (N=472) • Region: 64% New York city, 18% around NYC • Age: balanced across ages from 0-17 years • Gender: half male • Race and ethnicity: 23% white,40% black, 34% Hispanic • Income: 80% below 160% of FPL • Parent Employment: 83% had > 1 parent working • Prior Insurance: 71% uninsured >12m before SCHIP

Reasons for Improvement in Asthma(Among the 75% Who Improved)
Multivariate Results • Adjustments for Demographics did not affect findings • The “SCHIP effect” remained significant for most measures • Improvement in “unmet needs” only among Mild Asthma For most other measures, similar pattern if Mild or Severe “SCHIP Effect” ------Mild Asthma------ ------Severe Asthma------ Unadjusted Adjusted Unadjusted Adjusted ORPORPORPORP Unmet Needs .2 .006 .2 .007 .6 .6 .7 .6 Most Visits to USC 11 <.001 15 <.001 12 <.001 12 <.001

Limitations and Strengths Limitations: • Internal Validity • Self-report (especially for quality measures) • No perfect definition of asthma • Possible regression to the mean • External Validity: • One state • SCHIP (and not Medicaid) Strengths: • First study of SCHIP & asthma, Large N, High follow-up rate
Conclusions • Many children with asthma enrolled in SCHIP • For children with asthma, during SCHIP: • Improved access to care and reduced unmet needs • Change in pattern of care– more care at the USC • Improved quality- general (Overall rating, CAHPS, continuity) • Improved quality-asthma (Getting asthma care/meds, severity, rating) • Reduced parent worry • Reasons for improvements- now getting care or meds • Still suboptimal quality on several measures in spite of SCHIP • Tune-up visits and preventive meds for severe asthma • No improvement in general health status after SCHIP
Implications for Clinicians • Many children with asthma enrolling in SCHIP • Their baseline quality of care is poor even though most had a USC • Better use of medical home is associated with higher quality during SCHIP • Need to do more to improve quality measures • Asthma tune-up visits, preventive meds for severe asthma
Implications for Health Plans • Many children with asthma enrolling in plans • Quality of asthma can improve with coverage but will not reach standards • Encourage clinicians to improve quality of care for children with asthma
Implications for Policy Makers • SCHIP reduces barriers to asthma care and improves access and quality of asthma care • Coverage of asthma medications is important • SCHIP changed pattern of utilization • More use of USC, not more high-cost services (specialty, ED) • SCHIP may cause higher initial costs for asthma • SCHIP can have spill-over benefits: less parent worry/stress • SCHIP (?insurance) more likely to affect a condition-specific measure than a global health status measure
