Addressing adverse social determinants of health in pediatric primary care: Study protocol for a hybrid type 2 effectiveness-implementation randomized controlled trial in two national pediatric practice-based research networks.

BACKGROUND: Growing evidence linking social determinants of health (SDOH) to child health outcomes has prompted widespread recommendations for pediatricians to screen and refer for adverse SDOH at primary care visits. Yet there is little evidence to date demonstrating the effectiveness of practice-based SDOH screening and referral interventions on increasing family engagement with resources. This hybrid type 2 effectiveness-implementation trial aims to demonstrate the non-inferiority of a low-touch implementation strategy in order to facilitate dissemination of an existing SDOH screening and referral system (WE CARE) and demonstrate its effectiveness and sustainability in various pediatric practices. METHODS: We recruited eighteen pediatric practices in fourteen US states through two pediatric practice-based research networks. For this stepped wedge cluster RCT, practices serve as their own controls during the Usual Care phase and implement WE CARE during the intervention phase via one of two randomized implementation strategies: self-directed, pre-recorded webinar vs. study team-facilitated, live webinar. We collect data at practice, clinician/staff, and parent levels to assess outcomes grounded in the Proctor Conceptual Model of Implementation Research. We use generalized mixed effects models and differences in proportions to compare rates of resource referrals by implementation strategy, and intention-to-treat analysis to compare odds of engagement with new resources among families enrolled in the Usual Care vs. WE CARE phases. DISCUSSION: Findings from this trial may inform decisions about broader dissemination of SDOH screening systems into a diverse spectrum of pediatric practices across the US and potentially minimize the impact of adverse SDOH on children and families.

Reducing Antibiotic Prescribing in Primary Care for Respiratory Illness.

BACKGROUND: One-third of outpatient antibiotic prescriptions for pediatric acute respiratory tract infections (ARTIs) are inappropriate. We evaluated a distance learning program's effectiveness for reducing outpatient antibiotic prescribing for ARTI visits. METHODS: In this stepped-wedge clinical trial run from November 2015 to June 2018, we randomly assigned 19 pediatric practices belonging to the Pediatric Research in Office Settings Network or the NorthShore University HealthSystem to 4 wedges. Visits for acute otitis media, bronchitis, pharyngitis, sinusitis, and upper respiratory infection for children 6 months to <11 years old without recent antibiotic use were included. Clinicians received the intervention as 3 program modules containing online tutorials and webinars on evidence-based communication strategies and antibioti c prescribing, booster video vignettes, and individualized antibiotic prescribing feedback reports over 11 months. The primary outcome was overall antibiotic prescribing rates for all ARTI visits. Mixed-effects logistic regression compared prescribing rates during each program module and a postintervention period to a baseline control period. Odds ratios were converted to adjusted rate ratios (aRRs) for interpretability. RESULTS: Among 72 723 ARTI visits by 29 762 patients, intention-to-treat analyses revealed a 7% decrease in the probability of antibiotic prescribing for ARTI overall between the baseline and postintervention periods (aRR 0.93; 95% confidence interval [CI], 0.90-0.96). Second-line antibiotic prescribing decreased for streptococcal pharyngitis (aRR 0.66; 95% CI, 0.50-0.87) and sinusitis (aRR 0.59; 95% CI, 0.44-0.77) but not for acute otitis media (aRR 0.93; 95% CI, 0.83-1.03). Any antibiotic prescribing decreased for viral ARTIs (aRR 0.60; 95% CI, 0.51-0.70). CONCLUSIONS: This program reduced antibiotic prescribing during outpatient ARTI visits; broader dissemination may be beneficial.

Effectiveness of centralized text message reminders on human papillomavirus immunization coverage for publicly insured adolescents.

PURPOSE: We evaluated a managed care organization (MCO)-generated text message reminder-recall system designed to improve human papillomavirus (HPV) vaccination coverage. METHODS: We conducted a randomized controlled trial of text reminder-recall for parents of 3,812 publicly insured adolescents aged 11-16 years with no prior HPV vaccinations who were enrolled in a single MCO and were patients at one of 39 primary care practices. We determined the rate of HPV receipt for intervention versus control with the Kaplan-Meier failure function and determined hazard ratios using a clustered stratified Cox model, clustering on primary care provider and stratified on practice. We examined results for all subjects, and for those with a valid phone number, stratified by age group (11-13 years and 14-16 years) and gender. A post hoc analysis included all subjects and controlled for age and gender. RESULTS: HPV dose 1 vaccination rates were not significantly different when all participants were included, but for the subset of parents (54%) able to receive messages, HPV dose 1 rates were 13% for the control group and 16% for the intervention group; hazard ratio, 1.3 (95% confidence interval, 1.0-1.6; p = .04), when controlling for age and gender. There were no significant findings in the analysis stratified by age and gender. CONCLUSIONS: MCO-based text reminders are feasible and have a modest effect on HPV dose 1 vaccination rates for those parents able to receive text messages with valid phone numbers in the MCO database. Future studies should examine a similar intervention for those parents who already accepted the first HPV vaccine dose.

Patient-provider communication and human papillomavirus vaccine acceptance.

The authors performed telephone interviews of parents of adolescents (n = 430) and their older adolescents (n = 208) in Monroe County, New York to measure parent and adolescent acceptance of human papillomavirus (HPV) vaccine, its association with ratings of provider communication, and vaccine-related topics discussed with the adolescent's provider. More than half of adolescent girls had already received an HPV vaccination, with fewer than one quarter refusing. Parent and teen ratings of provider communication was high, and not related to HPV vaccine refusal. Parents were more likely to refuse if they were Hispanic (odds ratio [OR] = 5.88, P = .05) or did not consider vaccines "very safe" (OR = 2.76, P = .04). Most parents of boys (85%) believed males should be given HPV vaccine if recommended. Few parents and teens recalled discussing that vaccination does not preclude future Pap smear testing. Providers should address cultural and vaccine safety concerns in discussions about HPV vaccine.

Managed care quality and disenrollment in New York SCHIP.

BACKGROUND: During the past decade, experts have devoted substantial efforts to quality improvement for managed care. Although a handful of studies have examined the effect of quality on enrollment, few have systematically investigated the association between managed care quality and plan disenrollment, especially among lowincome populations. OBJECTIVE: To examine whether higher-quality measures in managed care plans are associated with lower disenrollment from the State Children's Health Insurance Program (SCHIP) in New York State. DESIGN, SETTING, AND PARTICIPANTS: Observational study of managed care plan disenrollment for a New York statewide cohort of 2206 new SCHIP enrollees. MEASUREMENTS: Managed care quality was measured by 7 Consumer Assessment of Health Plans Survey (CAHPS) scores and 3 Healthcare Effectiveness Data and Information Set (HEDIS) scores, obtained from the 2002 New York State Managed Care Plan Performance Report. Disenrollment was defined as being disenrolled from an SCHIP plan for 2 or more consecutive months based on the New York SCHIP universal billing files. RESULTS: Nearly 40% of children were disenrolled during the study period. No overall effects of plan quality on disenrollment were detected, but plans with higher scores in "preventive care visits" had a significantly lower disenrollment rate. The disenrollment rate in the eligibility recertification period was 3.2 percentage points higher than that in other time periods. CONCLUSION: Disenrollment was not associated with overall managed care plan quality as measured by CAHPS and HEDIS, suggesting that further study is warranted to determine optimal strategies for enhancing managed care quality in the SCHIP population.

Cost of universal influenza vaccination of children in pediatric practices.

OBJECTIVES: The goals were to estimate nationally representative pediatric practices' costs of providing influenza vaccination during the 2006-2007 season and to simulate the costs pediatric practices might incur when implementing universal influenza vaccination for US children aged 6 months to 18 years. METHODS: We surveyed a stratified, random sample of New York State pediatric practices (N = 91) to obtain information from physicians and office managers about all practice resources associated with provision of influenza vaccination. We estimated vaccination costs for 2 practice sizes (small and large) and 3 geographic areas (urban, suburban, and rural). We adjusted these data to obtain national estimates of the total practice cost (in 2006 dollars) for providing 1 influenza vaccination to children aged 6 months to 18 years. RESULTS: Among all respondents, the median total cost per vaccination was $28.62 (interquartile range: $18.67-45.28). The median component costs were as follows: clinical personnel labor costs, $2.01; nonclinical personnel labor costs, $7.96; all other (overhead) costs, $10.43. Vaccine purchase costs averaged $8.22. Smaller practices and urban practices had higher costs than larger or suburban practices. With the assumption of vaccine administration reimbursement for all Vaccines for Children (VFC)-eligible children at the current Medicaid median of $8.40, the financial loss across all US pediatric practices through delivery of VFC vaccines would be $98 million if one third of children received influenza vaccine. CONCLUSION: The total cost for pediatric practices to provide influenza vaccination is high, varies according to practice characteristics, and exceeds the average VFC reimbursement.

Managed care quality of care and plan choice in New York SCHIP.

OBJECTIVE: To examine whether low-income parents of children enrolled in the New York State Children's Health Insurance Program (SCHIP) choose managed care plans with better quality of care. DATA SOURCES: 2001 New York SCHIP evaluation data; 2001 New York State Managed Care Plan Performance Report; 2000 New York State Managed Care Enrollment Report. STUDY DESIGN: Each market was defined as a county. A final sample of 2,325 new enrollees was analyzed after excluding those in markets with only one SCHIP plan. Plan quality was measured using seven Consumer Assessment of Health Plans Survey (CAHPS) and three Health Plan Employer Data and Information Set (HEDIS) scores. A conditional logit model was applied with plan and individual/family characteristics as covariates. PRINCIPLE FINDINGS: There were 30 plans in the 45 defined markets. The choice probability increased 2.5 percentage points for each unit increase in the average CAHPS score, and the association was significantly larger in children with special health care needs. However, HEDIS did not show any statistically significant association with plan choice. CONCLUSIONS: Low-income parents do choose managed care plans with higher CAHPS scores for their newly enrolled children, suggesting that overall quality could improve over time because of the dynamics of enrollment.

Crowd-out in the State Children's Health Insurance Program (SCHIP): incidence, enrollee characteristics and experiences, and potential impact on New York's SCHIP.

BACKGROUND: The extent to which the State Children's Health Insurance Program (SCHIP) crowds our private insurance is poorly understood. OBJECTIVE: To assess the incidence of crowd-out and enrollee characteristics associated with crowd-out. DATA: Parent telephone survey for 2,644 children after enrollment in NY SCHIP. MEASURES AND ANALYSES: Crowd-out is measured based on enrollee reports of coverage (and loss of coverage) before SCHIP. Multivariate logistic regression is used to relate crowd-out to enrollee characteristics. PRINCIPAL FINDINGS: Only 7.1 percent of SCHIP enrollees dropped private coverage < or =6 months before SCHIP, suggesting relatively modest crowd-out. Crowd-out was associated with some enrollee traits including income, but not with health status. IMPLICATIONS: Most movement from private to public insurance in NY was not crowd-out. Under current program structure in NY, crowd-out concerns should not dampen enthusiasm for SCHIP.

The impact of health insurance gaps on access to care among children with asthma in the United States.

BACKGROUND: Health insurance coverage is important to help assure children appropriate access to medical care and preventive services. Insurance gaps could be particularly problematic for children with asthma, since appropriate preventive care for these children depends on frequent, consistent contacts with health care providers. OBJECTIVE: The aim of this study was to determine the association between insurance gaps and access to care among a nationally representative sample of children with asthma. METHODS: The National Survey of Children's Health provided parent-report data for 8097 children with asthma. We identified children with continuous public or continuous private insurance and defined 3 groups with gaps in insurance coverage: those currently insured who had a lapse in coverage during the prior 12 months (gained insurance), those currently uninsured who had been insured at some time during the prior 12 months (lost insurance), and those with no health insurance at all during the prior 12 months (full-year uninsured). RESULTS: Thirteen percent of children had coverage gaps (7% gained insurance, 4% lost insurance, and 2% were full-year uninsured). Many children with gaps in coverage had unmet needs for care (7.4%, 12.8%, and 15.1% among the gained insurance, lost insurance, and full-year uninsured groups, respectively). In multivariate models, we found significant associations between insurance gaps and every indicator of poor access to care among this population. CONCLUSIONS: Many children with asthma have unmet health care needs and poor access to consistent primary care, and lack of continuous health insurance coverage may play an important role. Efforts are needed to ensure uninterrupted coverage for these children.

Impact of the State Children's Health Insurance Program on adolescents in New York.

OBJECTIVES: Adolescents face financial and nonfinancial barriers to health care. Little is known about the impact of health insurance on health care for adolescents. We assessed the impact of New York's State Children's Health Insurance Program on access, use, and quality of care for adolescents. METHODS: Adolescents and their parents from a stratified random sample of new enrollees in New York's State Children's Health Insurance Program were interviewed by telephone shortly after enrollment (baseline, n = 1118 adolescents and their parents) and 1 year later (follow-up, n = 970). Outcome measures included access (having a usual source of care and reported unmet health needs), use (preventive care and other types of visits), and quality (satisfaction with care, receipt of confidential care and preventive counseling). Outcomes were assessed at baseline (year before the State Children's Health Insurance Program) versus follow-up (year during the State Children's Health Insurance Program). RESULTS: The proportion of adolescents who reported having a usual source of care increased during State Children's Health Insurance Program compared with before (69.9% to 87.1%). The proportion with any unmet health care need (54.3% to 42.1%) or with unmet need for preventive care (53.8% to 40.6%) decreased, with elimination of racial disparities that existed before the State Children's Health Insurance Program. After enrollment in the State Children's Health Insurance Program, more adolescents reported having had a preventive care visit (65.9% to 74.2%); emergency department use did not change. No differences in satisfaction were noted, although significant increases were noted in both parent- and adolescent-reported rates of having received confidential care and preventive counseling. CONCLUSIONS: Adolescents who enrolled in New York's State Children's Health Insurance Program experienced improved access, use, and quality of care. These findings suggest that the provision of health insurance can help to improve health care for adolescents.

Improved health care among children with special health care needs after enrollment into the State Children's Health Insurance Program.

OBJECTIVE: To assess the impact of New York's State Children's Health Insurance Program (SCHIP) on health care for children with special health care needs (CSHCN). METHODS: Little is known about the impact of health insurance on CSHCN. Parents of a stratified random sample of new enrollees onto New York's SCHIP were interviewed by telephone at enrollment (n = 2644) and 1 year later (n = 2290, 87% response). At baseline, the cohort of CSHCN was defined by means of the standardized CSHCN screener instrument. The impact of SCHIP was assessed for CSHCN and for subgroups of CSHCN stratified by prior insurance (uninsured or insured) or type of chronic condition (physical or mental/behavioral). Access (having a usual source of care [USC], unmet medical needs); and quality (continuity of care at the USC, parent rating of quality of care or worry about child) were measured. Bivariate and multivariate analyses compared measures 1 year before SCHIP versus the year during SCHIP. RESULTS: A total of 398 (17%) of 2290 children had special health care needs identified at baseline. Enrollment onto SCHIP was generally associated with improved access: unmet needs for prescription medications declined 3-fold for all subgroups (eg, 36% to 9% among the previously uninsured) and unmet needs for specialty care declined >4-fold among CSHCN who were previously insured (48% to 10%) or had mental/behavioral conditions (32% to 2%; all P < .05). Enrollment was associated with improved continuity with the USC, parent-reported quality of care, and worry, irrespective of prior insurance or type of chronic condition (P < .05). CONCLUSIONS: Enrollment onto New York's SCHIP improved medical care for CSHCN.

Short-term persistence of high health care costs in a nationally representative sample of children.

OBJECTIVES: Little is known about the persistence of health care costs in children. Determining whether children with high health expenses continue to have high expenses over time can help in the development of targeted programs and policies to decrease costs, plan equitable health insurance strategies, and provide insights into the effects of costly conditions on families. The objectives of this study were to (1) identify the characteristics of children who are in the top 10th percentile for health costs, (2) investigate whether those in the top percentiles for costs in 1 year continue in the same percentiles the next year, and (3) identify factors that predict whether a child stays in the top percentiles. METHODS: Data from 2 consecutive years (2000-2001) of the Medical Expenditure Panel Survey were analyzed. Changes in a child's position in the expenditure distribution were examined. An estimated multivariate model conditional on insurance was developed to predict the true resource costs of providing services. Statistical analyses, including logistic-regression and multivariate linear-regression modeling, were done to account for the weighted sampling used in Medical Expenditure Panel Survey. RESULTS: A total of 2938 children were included in the survey for both years. In 2000, the top 10% of the children accounted for 54% of all costs. They had a mean total expenditure of 6422 dollars with out-of-pocket expenditures of 1236 dollars; 49% of the children in the top decile in 2000 persisted in the top decile in 2001, whereas 12% dropped into the bottom half. Children who had been in the top 10% in 2000 were 10 times more likely than other children to be in the top 10% for 2001. Other characteristics in 2000 that predicted membership in the top decile for 2001 included age (11-15 and 16-17 years), having any insurance (public and private), being positive on the standardized Children With Special Health care Need screener, and having a functional limitation. CONCLUSIONS: Almost half of the children in the top 10% for costs in 2000 persisted in the top 10% in 2001. Older children, children with special health care needs, and children with functional limitations were more likely to be in the top decile. These findings do not support the belief that black and Latino children who are on Medicaid account for a disproportionate share of costs or expenditures. Because the children who were among the top 10% used health care services in a variety of inpatient, emergency department, outpatient, and ancillary venues, providing care coordination throughout the entire health care system is important to address both the cost and the quality aspects of health care for the most costly children. Targeted programs to decrease expenditures for those with the greatest costs have the potential to save future health care dollars. Assessment of the factors that predict persistence of high expenditures can be used to help in the planning of equitable health insurance strategies such as catastrophic care, carve-outs, reinsurance, and risk adjustment. Clinicians should review regularly the extent of care coordination that they are providing for their high-need and high-cost patients, especially preteens and adolescents. Studies that examine the persistence of expenditures over longer periods and include assessment of quality of care are needed.

Improved asthma care after enrollment in the State Children's Health Insurance Program in New York.

BACKGROUND: Uninsured children with asthma are known to face barriers to asthma care, but little is known about the impact of health insurance on asthma care. OBJECTIVES: We sought to assess the impact of New York's State Children's Health Insurance Program (SCHIP) on health care for children with asthma. DESIGN: Parents of a stratified random sample of new enrollees in New York's SCHIP were interviewed by telephone shortly after enrollment (baseline, n = 2644 [74% of eligible children]) and 1 year later (follow-up, n = 2310 [87%]). Asthma was defined by parent report using questions based on National Heart, Lung, and Blood Institute criteria. A comparison group (n = 401) who enrolled in SCHIP 1 year later was interviewed as a test for secular trends. MAIN OUTCOME MEASURES: Access (having a usual source of care [USC], unmet health needs, problems receiving acute asthma care), asthma-related medical visits, quality (continuity of care at the USC, problems receiving chronic asthma care, use of antiinflammatory medications), and asthma outcomes (change in asthma care or severity) were the main outcome measures used. Bivariate and multivariate analyses compared measures at baseline (year before SCHIP) versus follow-up (year during SCHIP). RESULTS: Three-hundred eighty-three children (14%) had asthma at baseline, and 364 had asthma at follow-up (16%). No secular trends were detected between the baseline study group and the comparison group. After enrollment in SCHIP, improvements were noted in access: lacking a USC (decrease from 5% to 1%), unmet health needs (48% to 21%), and problems getting to the USC for asthma (13 to 4%). Children had fewer asthma-related attacks and medical visits after SCHIP (mean number of attacks: 9.5 to 3.8: mean number of asthma visits: 3.0 to 1.5; hospitalizations: 11% to 3%). Quality of asthma care improved for general measures (most/all visits to USC: 53% to 94%; mean rating of provider: 7.9 to 8.8 of 10) and asthma-specific measures (problems getting to the USC for asthma care when child was well: 13% to 1%). More than two thirds of the parents at follow-up reported that both quality of asthma care and asthma severity were "better or much better" than at baseline, generally because of insurance coverage or lower costs of medications and medical care. CONCLUSIONS: Enrollment in New York's SCHIP was associated with improvements in access to asthma care, quality of asthma care, and asthma-specific outcomes. These findings suggest that health insurance improves the health of children with asthma.

Prior health care experiences of adolescents who enroll in SCHIP.

The State Children's Health Insurance Program (SCHIP) was designed to provide health insurance to low-income children and adolescents. Little is known about prior access to care and health care experiences of new SCHIP enrollees. We surveyed Florida and New York new adolescent SCHIP enrollees about their health status, prior health care utilization, access, and unmet needs. Most enrollees were younger (ages 12-16 years), Black or Hispanic, lived in poverty, and were without health insurance the year before SCHIP. Most had a usual source of care (USC) prior to enrollment; Blacks and Hispanics were less likely than Whites to have had a USC. Although 69% of Florida and 80% of New York adolescents reported seeing a physician the year before enrollment, 24% and 40%, respectively, reported unmet health care needs. Only 32% of Florida and 40% of the New York adolescents who were surveyed reported ever having met privately with their clinicians. Many new SCHIP enrollees report unmet needs, disparities in access, and sub-optimal care prior to enrollment. Adolescents' needs should be considered in SCHIP program and quality assurance efforts.

The State Children's Health Insurance Program.

PURPOSE OF REVIEW: The State Children's Health Insurance Program expanded public health insurance to children who are ineligible for Medicaid yet unable to afford private health insurance. The program was a natural experiment, offering the opportunity to study the effects of expanding health insurance to a large population of children who would otherwise be uninsured. The State Children's Health Insurance Program is reviewed in the context of program goals, evaluation dimensions, past and current findings, and future directions. The studies and findings fall into five dimensions: (1) outreach/enrollment/uptake and profile of enrollees, (2) impact on insurance coverage and uninsured rates, (3) coverage dynamics, (4) impact on outcomes, and (5) costs. RECENT FINDINGS: Older studies focused on outreach, enrollment, characteristics of enrollees, disenrollment, and coverage dynamics. Current studies report the impact of the program on outcomes--including access to care, quality, satisfaction, unmet need, and health outcomes--for the overall population of children and for vulnerable subgroups, including racial and ethnic minorities and children with chronic illness. A smaller number of studies address costs. SUMMARY: The State Children's Health Insurance Program is evolving with demonstrated successes and areas for improvement. This information can enhance practicing pediatricians' understanding of barriers that face low-income children and families in seeking care for their children, can offer insight into what health insurance can and cannot do in terms of ameliorating those barriers, can provide insight into the prior experiences and current medical needs that a new enrollee in the program might have at the first visit to a practitioner, and can illuminate the challenges that low-income children and families may face in obtaining and maintaining health insurance coverage.

Reduction in racial and ethnic disparities after enrollment in the State Children's Health Insurance Program.

BACKGROUND: Racial/ethnic disparities are associated with lack of health insurance. Although the State Children's Health Insurance Program (SCHIP) provides health insurance to low-income children, many of whom are members of racial/ethnic minority groups, little is known about whether SCHIP affects racial/ethnic disparities among children who enroll. OBJECTIVES: The objectives of this study were to (1) describe demographic characteristics and previous health insurance experiences of SCHIP enrollees by race, (2) compare racial/ethnic disparities in medical care access, continuity, and quality before and during SCHIP, and (3) determine whether disparities before or during SCHIP are explained by sociodemographic and health system factors. METHODS: Pre/post-parent telephone survey was conducted just after SCHIP enrollment and 1 year after enrollment of 2290 children who had an enrollment start date in New York State's SCHIP between November 2000 and March 2001, stratified by race/ethnicity (non-Hispanic white, non-Hispanic black, and Hispanic). The main outcome measures were usual source of care (USC), preventive care use, unmet needs, patterns of USC use, and parent-rated quality of care before versus during SCHIP. RESULTS: Children were white (25%), black (31%), or Hispanic (44%); 62% were uninsured > or =12 months before SCHIP. Before SCHIP, a greater proportion of white children had a USC compared with black or Hispanic children (95%, 86%, and 81%, respectively). Nearly all children had a USC during SCHIP (98%, 95%, and 98%, respectively). Before SCHIP, black children had significantly greater levels of unmet need relative to white children (38% vs 27%), whereas white and Hispanic children did not differ significantly (27% vs 29%). During SCHIP, racial/ethnic disparities in unmet need were eliminated, with unmet need at 19% for all 3 racial/ethnic groups. Before SCHIP, more white children made all/most visits to their USC relative to black or Hispanic children (61%, 54%, and 34%, respectively); all improved during SCHIP with no remaining disparities (87%, 86%, and 92%, respectively). Parent-rated visit quality improved for all groups, but preexisting racial/ethnic disparities remained during SCHIP, with improved yet relatively lower levels of satisfaction among parents of Hispanic children. Sociodemographic and health system factors did not explain disparities in either period. CONCLUSIONS: Enrollment in SCHIP was associated with (1) improvement in access, continuity, and quality of care for all racial/ethnic groups and (2) reduction in preexisting racial/ethnic disparities in access, unmet need, and continuity of care. Racial/ethnic disparities in quality of care remained, despite improvements for all racial groups. Sociodemographic and health system factors did not add to the understanding of racial/ethnic disparities. SCHIP improves care for vulnerable children and reduces preexisting racial/ethnic disparities in health care.

SCHIP's impact in three states: how do the most vulnerable children fare?

This study provides consistent evidence, from three very diverse states with heterogeneous populations and distinct programs (Florida, Kansas, and New York), that the State Children's Health Insurance Program (SCHIP) increased access to and satisfaction with health care among enrolled low-income children and that vulnerable children-minorities, children and adolescents with special health care needs, and children who were uninsured for long periods of time-shared in these improvements. We highlight some areas to target for future improvement, such as reducing the high levels of unmet needs among special-needs children and increasing preventive care, especially for Hispanic children.
