Gradients in the health status and developmental risks of young children: the combined influences of multiple social risk factors.
OBJECTIVES: To analyze child vulnerability as a profile of multiple risk factors for poorer health based on race/ethnicity, social class (maternal education and family poverty status), child health insurance coverage, and maternal mental health. Profiles are examined in relation to disparities in the health status and developmental risks of young children. DATA SOURCES: Cross-sectional data on 2,068 children ages 4-35 months from the 2000 National Survey of Early Childhood Health. STUDY DESIGN: Multiple logistic regression models are used to examine risk profiles in relation to child health status and developmental risk (based on parent concerns about development). The profiles are also examined in relation to three measures of basic access to health care: telephone contact with a physician, well-child visit in the past year, and missed or delayed needed care. PRINCIPAL FINDINGS: About one-third of (or 3.1 million) young children in the United States have two or more risk factors (RF) for poor health. Controlling for other family factors, having more RFs is associated with poorer health status (i.e., percent reported "good/fair/poor" vs. "excellent/very good") and being higher risk for developmental delays. For example, the likelihood of having either poorer health or higher developmental risk increases with each RF (vs. zero): 1 RF (OR = 1.70, CI: 1.20-2.38), 2 RFs (OR = 3.28, CI: 2.27-4.73), 3 RFs (OR = 4.69, CI: 2.84-7.73), 4 RFs (OR = 14.58, CI: 4.98-42.64). Higher RFs were also associated with poorer health care access. CONCLUSIONS: This study demonstrates a dose-response relationship of higher risk profiles with poorer child health status and higher developmental risk. Because children with higher profiles of risk are also more likely to lack access to care, this suggests that children who most need care have the greatest difficulty obtaining it. Addressing health gradients for vulnerable children will require explicit attention to these multiple, overlapping risk factors.

Disparities in primary care for vulnerable children: the influence of multiple risk factors.
OBJECTIVES: To analyze vulnerability as a profile of multiple risk factors for poor pediatric care based on race/ethnicity, poverty status, parent education, insurance, and language. Profiles are used to examine disparities in child/adolescent health status and primary care experience. DATA SOURCES: Cross-sectional data on 19,485 children/adolescents 0-19 years of age from the 2001 California Health Interview Survey. STUDY DESIGN: Multiple logistic regression models are used to examine risk profiles in relation to health status and three aspects of primary care: access (physician and dental visit; access surety), continuity (regular source of care), and comprehensiveness (i.e., health promotion counseling). PRINCIPAL FINDINGS: About 43 percent of (or 4.4 million) children in California have two or more risk factors (RF). Controlling for age and gender, more RFs is associated with poorer health status (i.e. percent reporting "excellent/very good" health: no RFs=81 percent, 1=71 percent, 2=57 percent, 3=45 percent, 4=35 percent, 5=28 percent, all p<.001). Controlling for health status, higher risk profiles is associated with poorer primary care access and continuity, but greater comprehensiveness of care. For example, higher risk profile children are less likely to have a regular source of care: one RF (prevalence ratio [PR]=0.92, confidence interval [CI]: 0.86-0.98), two (PR=0.77, CI: 0.69-0.84), three (PR=0.55, CI: 0.46-0.65), and four or more (PR=0.31, CI: 0.22-0.44), all p<.001. CONCLUSIONS: This study demonstrates a dose-response relationship of higher risk profiles with poorer child health status, access to, and continuity of primary care. Having gained access, however, adolescents with higher risk profiles are more likely to receive health promotion counseling. Higher profiles appear to be associated with greater barriers to accessing primary care for children in "fair or poor" health, suggesting that vulnerable children who have the greatest health care needs also have the greatest difficulty obtaining primary care.

Enrolling vulnerable, uninsured but eligible children in public health insurance: association with health status and primary care access.
OBJECTIVES: Given that more than two thirds of uninsured children in California are eligible for public health insurance coverage, this study examined differences in primary care access and health status between uninsured but eligible (UBE) children and those who were insured. METHODS: Using data on 19485 children from the 2001 California Health Interview Survey, this study examined differences in primary care access and health status for UBE children versus those who were enrolled in public coverage. Results are stratified by profiles of other risk factors (RF) for poor access: nonwhite, low income, low parent education, and non-English speaking. RESULTS: UBE children were less likely than publicly enrolled children to have a physician visit in the past year, dental visit in the past year, and a regular source of care. On the basis of differences between the UBE children and enrollees in the prevalence of each dependent measure, UBE children with multiple RFs experienced greater disparities than UBE children with fewer RFs. For example, enrollees were more likely than UBE children to have a regular source of care among children with 2, 3, or 4 RFs (differences of 26, 26, and 25 percentage points, respectively) compared with 1 RF (19 percentage points) and 0 RFs (12 percentage points). A similar pattern was found for dental visits but not physician visits. Although there was no difference in health status between UBE children and enrollees overall, enrollees were more likely than UBE children to have excellent/very good health status among children with 2 RFs (difference of 9 percentage points), 3 RFs (12 percentage points), and 4 RFs (11 percentage points). CONCLUSIONS: This study demonstrates that UBE children in California have poorer access to care compared with enrollees, and those with the highest levels of risk have poorer health status. This suggests that providing insurance to these children (and particularly those with multiple RFs) may lead to improved access and health for these vulnerable children.

The parent-provider relationship: does race/ethnicity concordance or discordance influence parent reports of the receipt of high quality basic pediatric preventive services?
Recent research among adults suggests that having a provider of the same race/ethnicity may enhance the quality of health care above and beyond just having any regular source of care. It is not known whether such relationships exist in pediatric care. The purpose of this study is to identify the distribution and methods by which families have a race/ethnicity concordant provider of well-child care and examine whether differences exist in the receipt of basic preventive services (BPS) and family-centered care (FCC) among those with concordant, discordant, and no regular providers. Analyses are stratified by geography to assess whether urban versus nonurban setting moderates these differences. This study uses publicly available data from the 2000 National Survey of Early Childhood Health (NSECH), a nationally representative, cross-sectional telephone survey of parents of children ages 4-35 months (n = 1,996). African Americans and Latinos were more likely than whites to lack a regular provider of well-child care (60.9% and 65.7% vs. 50.6%) and less likely to have a concordant provider (9.8% and 5.7% vs. 38.5%) (P < .001). African Americans with a regular provider were about three times more likely to establish a concordant relationship in urban versus nonurban settings (32.4% vs. 12.5%, P < .01). No statistically significant differences in BPS or FCC were found by concordance versus discordance for any group, a finding that held regardless of geographic setting. White children with no regular provider received better BPS than those with a discordant provider (e.g., excellent BPS of 37.2% vs. 27.1%, P < .05), but children with no regular provider were more likely than those with either concordant or discordant providers to have lower FCC in one (Latinos, whites) or three domains (African Americans). Despite racial/ethnic differences in the likelihood of having a concordant regular provider of well-child care, no disparities were found in BPS or FCC associated with discordance, even after stratification by urban/nonurban setting. Lacking a regular provider was associated with lower FCC versus having either a concordant or discordant provider, suggesting that efforts to improve these aspects of well-child care might focus less on linking children with a race/ethnicity concordant provider and more on social, cultural, and linguistic factors that impact having any regular provider.

Vulnerability and the receipt of recommended preventive services: the influence of multiple risk factors.
CONTEXT: Previous studies have confirmed the independent associations of race/ethnicity, socioeconomic status, and potential access with the receipt of preventive care. More pragmatic models of vulnerability are needed to examine the concomitant influence of multiple risk factors. OBJECTIVE: To operationalize vulnerability as risk profiles of predisposing (race/ethnicity and education) and enabling (eg, income, health insurance, and having a regular source of care) factors, and their association with the receipt of preventive care. STUDY DESIGN: Cross-sectional data on 14,983 adults from the Household Component of the 1996 Medical Expenditure Panel Survey. MAIN OUTCOME MEASURES: Receipt of recommended preventive care: blood pressure and cholesterol screening, flu shot, Papanicolaou test, mammogram, and dental visit. RESULTS: Controlling for other factors, analyses of risk profiles revealed a clear dose-response relationship with the receipt of preventive care regardless of race/ethnicity. In the total sample, having more risk factors was associated with a lower prevalence of, for example, receiving a cholesterol screening: 1 risk (PR=0.77; CI, 0.71-0.84), 2 risks (PR=0.56; CI, 0.49-0.64), and 3+ risks (PR=0.34; CI, 0.25-0.43). CONCLUSION: Sizeable disparities in the receipt of recommended preventive services were found in relation to increasing vulnerability risk profiles. Without attention to such co-occurring risks, it is unlikely that substantial gains will be made in reducing disparities in the incidence of and mortality from the most common preventable diseases in the United States.

Access to care and children's primary care experiences: results from a prospective cohort study.
OBJECTIVE: To examine whether and how different kinds of access to care (financial, potential, and realized) predict parent-report child primary care experiences in an urban community sample. DATA SOURCES/STUDY SETTING: A prospective cohort study was performed. Baseline survey data were collected (67 percent response rate) from 3,406 parents of kindergarten through sixth grade students in a large urban school district in California during the 1999-2000 school year. A 1-year survey (80.4 percent response rate) resulted in a final sample of 2,738. STUDY DESIGN: Data were analyzed using multiple regression models with robust estimation. The dependent variable was Time 2 parent reports of primary care experiences, assessed via the Parents' Perceptions of Primary Care (P3C) measure. The independent variables were financial access (insurance status), potential access (presence of a regular source of care), and realized access (foregone care), controlling for child and family characteristics (race/ethnicity, parent's language, mother's education level, and child chronic health condition status) and baseline P3C scores. DATA COLLECTION: Data were collected by mail, telephone, and in person in English, Spanish, Vietnamese, and Tagalog. PRINCIPAL FINDINGS: Controlling for baseline P3C scores and child and family characteristics, having no health insurance at both baseline and Time 2 was associated with a 6.2-point lower Time 2 P3C score, relative to having had health insurance at both time points. Having a regular provider at Time 2 (either always having had one or gaining one during the year) was associated with, on average, a 10-point higher Time 2 P3C score, compared to children without a regular provider (either never having had one or losing one during the year). Episodes of foregone care during the year were associated with 10.7 points lower Time 2 P3C scores, relative to children whose parents did not report foregone care. Similar relationships were found between all three measures of access to care and each of the sub-domain measures of primary care experience. CONCLUSIONS: Financial, potential, and realized access to care are associated prospectively with the full range of primary care experiences--comprehensiveness, communication, coordination, and contextual knowledge--beyond continuity and accessibility. Access to a regular source of care and to needed care are each associated with larger effects on primary care experiences than is the presence of health insurance. Gaining insurance or a regular source of care results in primary care experiences similar to always having had these, while losing a regular source of care has a more immediate effect than losing insurance on primary care experiences.

Vulnerability and unmet health care needs. The influence of multiple risk factors.
CONTEXT: Previous studies have demonstrated a strong association between minority race, low socioeconomic status (SES), and lack of potential access to care (e.g., no insurance coverage and no regular source of care) and poor receipt of health care services. Most studies have examined the independent effects of these risk factors for poor access, but more practical models are needed to account for the clustering of multiple risks. OBJECTIVE: To present a profile of risk factors for poor access based on income, insurance coverage, and having a regular source of care, and examine the association of the profiles with unmet health care needs due to cost. Relationships are examined by race/ethnicity. DESIGN: Analysis of 32,374 adults from the 2000 National Health Interview Survey. MAIN OUTCOME MEASURES: Reported unmet needs due to cost: missing/delaying needed medical care, and delaying obtaining prescriptions, mental health care, or dental care. RESULTS: Controlling for personal demographic and community factors, individuals who were low income, uninsured, and had no regular source of care were more likely to miss or delay needed health care services due to cost. After controlling for these risk factors, whites were more likely than other racial/ethnic groups to report unmet needs. When presented as a risk profile, a clear gradient existed in the likelihood of having an unmet need according to the number of risk factors, regardless of racial/ethnic group. CONCLUSION: Unmet health care needs due to cost increased with higher risk profiles for each racial and ethnic group. Without attention to these co-occurring risk factors for poor access, it is unlikely that substantial reductions in disparities will be made in assuring access to needed health care services among vulnerable populations.

America's Health Centers: reducing racial and ethnic disparities in perinatal care and birth outcomes.
OBJECTIVE: To examine whether community health centers (CHCs) reduce racial/ethnic disparities in perinatal care and birth outcomes, and to identify CHC characteristics associated with better outcomes. BACKGROUND: Despite great national wealth, the U.S. continues to rank poorly relative to other industrialized nations on infant mortality and other birth outcomes, and with wide inequities by race/ethnicity. Disparities in primary care (including perinatal care) may contribute to disparities in birth outcomes, which may be addressed by CHCs that provide safety-net medical services to vulnerable populations. METHODS: Data are from annual Uniform Data System reports submitted to the Bureau of Primary Health Care over six years (1996-2001) by about 700 CHCs each year. RESULTS: Across all years, about 60% of CHC mothers received first-trimester prenatal care and more than 70% received postpartum and newborn care. In 2001, Asian mothers were the most likely to receive both postpartum and newborn care (81.7% and 80.3%), followed by Hispanics (75.0% and 76.3%), blacks (70.8% and 69.9%), and whites (70.7% and 66.7%). In 2001, blacks had higher rates of low birth weight (LBW) babies (10.4%), but the disparity in rates for blacks and whites was smaller in CHCs (3.3 percentage points) compared to national disparities for low-socioeconomic status mothers (5.8 percentage points) and the total population (6.2 percentage points). In CHCs, greater perinatal care capacity was associated with higher rates of first-trimester prenatal care, which was associated with a lower LBW rate. CONCLUSION: Racial/ethnic disparities in certain prenatal services and birth outcomes may be lower in CHCs compared to the general population, despite serving higher-risk groups. Within CHCs, increasing first-trimester prenatal care use through perinatal care capacity may lead to further improvement in birth outcomes for the underserved.

Prevalence and correlates of high-quality basic pediatric preventive care.
BACKGROUND: The list of recommended pediatric preventive services has grown considerably in the past decade, and clinician variability, clinician distribution, and other correlates of provision of these basic preventive services (BPS) are not known. OBJECTIVE: To describe the proportion of high-quality basic pediatric preventive services, exclusive of immunizations, reported by parents and to identify sociodemographic and health system predictors and health service correlates of provision of these services. STUDY DESIGN: The study used cross-sectional data on 2041 children, 4 to 35 months of age, in the 2000 National Survey of Early Childhood Health. OUTCOME MEASURES: The BPS measure assesses the receipt of (1) developmental assessment, (2) injury prevention counseling, (3) screening for parental smoking, (4) guidance on reading to the child, and (5) guidance on 14 other topics (assessed as a composite score). The BPS scale categorizes the receipt of services as excellent, good, fair, or poor. RESULTS: Most children received excellent (34.9%) or good (31.5%) care, but many received fair (24.9%) or poor (8.7%) care. Sociodemographic and health care factors such as race/ethnicity, insurance, and practice setting were not associated with BPS levels. Higher BPS scores were associated with parental reports of longer well-child visits, more counseling regarding family and community risk factors, lower rates of delayed or missed care, and greater satisfaction. CONCLUSIONS: Two thirds of children receive good or excellent basic preventive care, as determined with this composite, and no disparities according to race/ethnicity, income, or health insurance status of families (which are often found to be associated with health care access) were found. This equitable distribution of high-quality care suggests a high level of clinician professionalism. Duration of visits may be a key factor to improve quality of care. Because of its association with other services, processes, and outcomes of care, the BPS scale may serve as a useful construct for monitoring quality and stimulating efforts to improve national pediatric preventive care.

Parents' perceptions of pediatric primary care quality: effects of race/ethnicity, language, and access.
OBJECTIVE: To examine the effects of race/ethnicity, language, and potential access on parents' reports of pediatric primary care experiences. DATA SOURCES/STUDY SETTING: Primary survey data were collected (67 percent response rate) from 3,406 parents of students in kindergarten through sixth grade in a large urban school district in California during the 1999-2000 school year. DATA COLLECTION: The data were collected by mail, telephone, and in person. Surveys were administered in English, Spanish, Vietnamese, and Tagalog. STUDY DESIGN: Data were analyzed using multiple regression models. The dependent variable was parents' reports of primary care quality, assessed via the previously validated Parents' Perceptions of Primary Care measure (P3C). The independent variables were race/ethnicity, language, and potential access to care (insurance status, presence of a regular provider of care), controlling for child age, gender, and chronic health condition status, and mother's education. PRINCIPAL FINDINGS: Parents' reports of primary care quality varied according to race/ethnicity, with Asian and Latino parents reporting lower P3C scores than African Americans and whites. In multivariate analyses, both language and potential access exerted strong independent effects on primary care quality, reducing the effect of race/ethnicity such that the coefficient for Latinos was no longer significant, and the coefficient for Asians was much smaller, though still statistically significant. CONCLUSIONS: To reduce racial/ethnic disparities in primary care, attention should be paid both to policies aimed at improving potential access and to providing linguistically appropriate services.

Racial and ethnic disparities in the primary care experiences of children: a review of the literature.
Substantial racial and ethnic disparities persist in children's health and use of health services in the United States. Although equitable access to primary care services is widely promoted as one of the most feasible remedies to reduce health disparities, there has only recently been an effort to assess its quality, particularly for children. Racial and socioeconomic differences in access to care have been previously well documented, but recent research has begun to elucidate differences in more qualitative experiences in the receipt of primary care. This article presents a synthesis and critique of the existing research according to the core attributes of primary care: first-contact care, longitudinality, comprehensiveness, and coordination. Finally, the article proposes an agenda for further research into the pathways by which racial and ethnic disparities in primary care exist.

Effect of managed care on children's relationships with their primary care physicians: differences by race.
CONTEXT: Racial and ethnic disparities in the quality of the patient-provider relationship have been documented previously, but only among adults. Few studies have examined this aspect of primary care quality for children, and none has examined the role of managed care in mediating disparities. OBJECTIVE: To explore variations in the associations among 3 managed care policies and the sustained patient-provider relationship for children by racial and ethnic group. DESIGN, SETTING, AND PARTICIPANTS: Telephone survey of parents of a random sample of 413 children attending elementary school in a large school district spanning 3 cities in southern California. Self-reported managed care information was validated through contact with health plan representatives. MAIN OUTCOME MEASURE: Parent reporting of the strength of affiliation and interpersonal relationships among the child, the family, and the health care provider. RESULTS: Parents of Hispanic and black children reported significantly lower strength of affiliation than whites did (mean, 3.19 and 3.27 vs 3.57; P<.05 and P<.01, respectively). Asians and Hispanics reported significantly poorer interpersonal relationships with providers than whites did (mean, 3.35 and 3.38 vs 3.53; P<.05 for both). Managed care policies requiring patients to (1) sign up with a particular provider, (2) seek a referral for specialty care, and (3) stay within a network were associated with reductions in the interpersonal relationship. All minority groups, but not whites, reported significantly poorer relationships when managed care policies were present. Asian children were most sensitive to the managed care policies. CONCLUSIONS: Our data suggest that racial and ethnic minority children experience poorer patient-provider relationships compared with white children, even controlling for socioeconomic status and health system factors. Minority children are particularly sensitive to managed care policies that restrict patient freedom in choosing where to seek care. Implementing less restrictive policies may enhance the development of the patient-provider relationship.

Health outcomes and medicaid costs for frail older individuals: a case study of a MCO versus fee-for-service care.
Older individuals receiving both Medicare and Medicaid benefits are known to have a disproportionate burden of illness and high medical care costs. Elder Health, Inc., a private, for-profit managed care organization operating in Maryland under capitation rates from both Medicare and Medicaid, has tailored a medical practice to these individuals, with the stated objective of providing integrated care. This study compared 200 Elder Health patients with a closely matched group of dually eligible older individuals receiving care in fee-for-service practices. There was a baseline in-home structured interview with the patient, followed 1 year later with a telephone interview. Other data sources were Medicaid claims data and Elder Health's utilization records. The outcomes of interest were the patients' health and functional status, their satisfaction with care, rates of use of medical services, and costs to Medicaid. Elder Health patients had similar general health status, better functional status, and greater satisfaction with access to care but less satisfaction with information giving than the fee-for-service group. They received more primary care and preventive services and had less than half the number of hospital days. Costs to Medicaid were nearly identical. Institutional and community-based long-term care costs were not included in the analysis.As pressures mount for the Health Care Financing Administration to expand its prepaid contracts with private health plans and the need for integrated programs increase, quantitative assessment of innovative delivery models such as Elder Health, Inc. will be essential to ensure that patients' and the publics' interests are well served.

Racial and ethnic disparities in the quality of primary care for children.
OBJECTIVES: Healthy People 2010 calls for greater access to high-quality primary care as a means to reduce racial and ethnic disparities in children' health. Disparities in primary care quality have rarely been studied for children, and the few studies that have been conducted among adults are not readily applicable to children because of the different health care needs of the 2 populations. This study compared the quality of primary care experienced specifically by children of different racial and ethnic groups. STUDY DESIGN: We used a random cross-sectional community sample of children. Parents were questioned via structured telephone interview with the Primary Care Assessment Tool about a selected child's primary care experiences. Responses were compared across racial and ethnic groups, with white children as the reference group. POPULATION: The sample consisted of parents of 413 elementary school children, ages 5 to 12 years, enrolled in 1 school district spanning 3 suburban cities in San Bernardino County, California. OUTCOMES MEASURED: We measured cardinal features of primary care quality including first-contact care (accessibility and utilization), longitudinality (strength of affiliation and interpersonal relationship), comprehensiveness (services offered and received), and coordination of care. RESULTS: After controlling for family demographics, socioeconomic status, and health system characteristics, minority children experienced poorer quality of primary care across most domains of care compared with white children. Asian Americans reported the lowest quality of care across most domains, but particularly in first-contact utilization, interpersonal relationship, and comprehensiveness of services received. CONCLUSIONS: Racial and ethnic disparities in quality persist in many aspects of primary care delivery. The findings suggested that these disparities are not simply reflections of ability to pay, health disparities, sociodemographics, or racial variations in expectations for care. The findings in this study that parents of minority children, in particular Asian Americans, report lower quality of primary care is consistent with previous research among adults but had not been demonstrated previously for children.
