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 Childrens 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 States 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 ≥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.

Vaccine Effectiveness Against Laboratory-Confirmed Influenza in Children 6 to 59 Months of Age During the 2003–2004 and 2004–2005 Influenza Seasons

OBJECTIVE. The goal was to estimate the effectiveness of influenza vaccination against laboratory-confirmed influenza during the 2003–2004 and 2004–2005 influenza seasons in children 6 to 59 months of age. METHODS. We conducted a case-control study with children with medically attended, acute respiratory infections who received care in an inpatient, emergency department, or outpatient clinic setting during 2 consecutive influenza seasons. All children residing in Monroe County, New York, Davidson County, Tennessee, or Hamilton County, Ohio, were enrolled prospectively at the time of acute illness and had nasal/throat swabs tested for influenza with cultures and/or polymerase chain reaction assays. Children with laboratory-confirmed influenza were case subjects and children who tested negative for influenza were control subjects. Child vaccination records from the parent and the childs physician were used to determine and to validate influenza vaccination status. Influenza vaccine effectiveness was calculated as (1 − adjusted odds ratio) × 100. RESULTS. We enrolled 288 case subjects and 744 control subjects during the 2003–2004 season and 197 case subjects and 1305 control subjects during the 2004–2005 season. Six percent and 19% of all study children were fully vaccinated according to immunization guidelines in the respective seasons. Full vaccination was associated with significantly fewer influenza-related inpatient, emergency department, or outpatient clinic visits in 2004–2005 (vaccine effectiveness: 57%) but not in 2003–2004 (vaccine effectiveness: 44%). Partial vaccination was not effective in either season. CONCLUSIONS. Receipt of all recommended doses of influenza vaccine was associated with halving of laboratory-confirmed influenza-related medical visits among children 6 to 59 months of age in 1 of 2 study years, despite suboptimal matches between the vaccine and circulating influenza strains in both years.

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 Yorks State Childrens Health Insurance Program (SCHIP) on health care for children with asthma. DESIGN. Parents of a stratified random sample of new enrollees in New Yorks 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 Yorks 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.

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 Childrens 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.

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.

The Role of Parent Health Literacy Among Urban Children with Persistent Asthma

UNLABELLED Health literacy (HL) affects adult asthma management, yet less is known about how parent HL affects child asthma care. OBJECTIVE To examine associations between parent HL and measures related to child asthma. METHODS Parents of 499 school-age urban children with persistent asthma in Rochester, New York completed home interviews. MEASURES the Rapid Estimate of Adult Literacy in Medicine (REALM) for parent HL; National Heart Lung and Blood Institute (NHLBI) criteria for asthma severity, and validated measures of asthma knowledge, beliefs, and experiences. ANALYSES bivariate and multivariate analyses of associations between parent HL measures related to child asthma. RESULTS Response rate: 72%, mean child age: 7.0 years. Thirty-two percent had a Hispanic parent; 88% had public insurance. Thirty-three percent had a parent with limited HL. Low parent HL was independently associated with greater parent worry, parent perception of greater asthma burden, and lower parent-reported quality of life. MEASURES of health care use (e.g., emergency care and preventive medicines) were not associated with parent HL. CONCLUSIONS Parents with limited HL worried more and perceived greater overall burden from the childs asthma, even though reported health care use did not vary. PRACTICE IMPLICATIONS Improved parent understanding and provider-parent communication about child asthma could reduce parent-perceived asthma burden, alleviate parent worry, and improve parent quality of life.

Decline in physician referrals to health department clinics for immunizations: the role of vaccine financing.

BACKGROUND Physicians frequently refer children to health department clinics (HDCs) for immunizations because of high out-of-pocket costs to parents and poor reimbursement for providers. Referrals for immunizations can lead to scattered care. In 1994, two vaccine financing reforms began in New York State that reduced patient costs and improved provider reimbursement: the Vaccines for Children Program (VFC, mostly for those on Medicaid and uninsured) and a law requiring indemnity insurers to cover childhood immunizations and preventive services. OBJECTIVE To measure reported changes in physician referrals to HDCs for immunizations before and after the vaccine financing reforms. DESIGN In 1993, a self-administered survey measured immunization referral practices of primary care physicians. In 1997, we resurveyed respondents of the 1993 survey to evaluate changes in referrals. SETTING/ PARTICIPANTS Three hundred twenty-eight eligible New York State primary care physicians (65% pediatricians and 35% family physicians) who responded to the 1997 follow-up immunization survey (response rate of 82%). RESULTS The proportion of physicians reporting that they referred some or all children out for immunizations decreased from 51% in 1993 to 18% in 1997 (p<0.001). In 1997, physicians were more likely to refer if they were family physicians (28% vs. 13%,p<0.01), or did not obtain VFC vaccines (29% vs. 13%,p<0.001). According to physicians who referred in 1993, decreased referrals in 1997 were due to the new insurance laws (noted by 61%), VFC (60%), Child Health Plus (a statewide insurance program for poor children, 28%), growth in commercial managed care (23%), Medicaid managed care (19%), and higher Medicaid reimbursement for immunizations that is due to VFC (18%). For physicians noting a decline in referrals, the magnitude of the decline was substantial-60% fewer referrals for VFC-eligible patients and 50% fewer for patients eligible under the new insurance law. CONCLUSIONS Vaccine financing reforms decreased the proportion of physicians who referred children to HDCs for immunizations, and may have reduced scattering of pediatric care.

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 Childrens 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.

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 childs 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
