America's Health Centers: reducing racial and ethnic disparities in perinatal care and birth outcomes

Prevalence of Access to Prenatal Care in the First Trimester of Pregnancy Among Black Women Compared to Other Races/Ethnicities: A Systematic Review and Meta-Analysis

Objective: To analyze the prevalence of access to prenatal care in the first trimester of pregnancy among black women compared to other races/ethnicities through a systematic review and meta-analysis.

Methods: Searches were carried out at PUBMED, LILACS, Web of Science, Scopus, CINAHL, and in the grey literature. The quality of the studies and the risk of bias were analyzed using the Joanna Briggs Critical Appraisal Checklist for Analytical Cross-Sectional Studies instrument. The extracted data were tabulatesd and analyzed qualitatively and quantitatively through meta-analysis.

Results: Black women had the lowest prevalence of access to prenatal services in the first trimester, with prevalence ranging from 8.1% to 74.81%, while among white women it varied from 44.9 to 94.0%; 60.7% of black women started prenatal care in the first trimester, while 72.9% of white women did so.

Conclusion: Black women compared to other racial groups had lower prevalence of access to prenatal care, with less chance of access in the first trimester, and it can be inferred that the issue of race/skin color is an important determinant in obtaining obstetric care.

Postpartum Visit Attendance in the United States: A Systematic Review

INTRODUCTION

Adequate postpartum care, including the comprehensive postpartum visit, is critical for long-term maternal health and the reduction of maternal mortality, particularly for people who may lose insurance coverage postpartum. However, variation in previous estimates of postpartum visit attendance in the United States makes it difficult to assess rates of attendance and associated characteristics.

METHODS

We conducted a systematic review of estimates of postpartum visit attendance. We searched PubMed, CINAHL, PsycInfo, and Web of Science for articles published in English from 1995 to 2020 using search terms to capture postpartum visit attendance and use in the United States.

RESULTS

Eighty-eight studies were included in this analysis. Postpartum visit attendance rates varied substantially, from 24.9% to 96.5%, with a mean of 72.1%. Postpartum visit attendance rates were higher in studies using patient self-report than those using administrative data. The number of articles including an estimate of postpartum visit attendance increased considerably over the study period; the majority were published in 2015 or later.

CONCLUSIONS

Our findings suggest that increased systematic data collection efforts aligned with postpartum care guidelines and attention to postpartum visit attendance rates may help to target policies to improve maternal wellbeing. Most estimates indicate that a substantial proportion of women do not attend at least one postpartum visit, potentially contributing to maternal morbidity as well as preventing a smooth transition to future well-woman care. Estimates of current postpartum visit attendance are important for informing efforts that seek to increase postpartum visit attendance rates and to improve the quality of care.

Community Health Centers' Performance in Cancer Screening and Prevention

INTRODUCTION

Little is known about what clinic-level factors differentiate community health centers that achieve high performance on cancer-preventive care metrics. This study aims to describe the longitudinal trends in the delivery of 3 cancer-preventive care metrics (cervical and colorectal cancer screenings and tobacco-cessation intervention) and define and compare community health centers with high cancer-preventive care performance with those with low cancer-preventive care performance.

METHODS

This observational study used 2012-2019 community health center data (N=933) from the Uniform Data System. High/low performance was based on Healthy People 2020 targets and sample distribution. For each cancer-preventive care metric, the percentage of community health centers that met high (≥70.5% at cervical or colorectal cancer screening or >80% tobacco-cessation intervention) and low thresholds at 1, 2, and all the 3 screenings was estimated. Multivariable generalized estimating equations logistic regression modeling was used to assess the community health center‒level factors associated with screening performance.

RESULTS

The community health centers' performance for tobacco-cessation intervention remained at ≥80%, with a small increase over time. Performance for cervical cancer screening remained unchanged with about 50% of patients screened. Colorectal cancer screening performance increased from around 30% in 2012 to 44% in 2019. Very few community health centers reached high performance (3%) in all the 3 indicators, and 13% of community health centers were high in any 2 of the outcomes in 2019. Higher patient volume, a greater proportion of Hispanic patients, fewer uninsured patients, and community health centers located in the Northeast region were associated with high performance in 2019.

CONCLUSIONS

Very few community health centers meet all Healthy People 2020 goals in cancer screenings and may struggle to achieve the 2030 goals. Very few indicators differentiated high performers from low performers.

Correlates of Receiving Guideline-Concordant Postpartum Health Services in the Community Health Center Setting

Introduction: New clinical guidelines recommend comprehensive and timely postpartum services across 3 months after birth. Research is needed to characterize correlates of receiving guideline-concordant, quality postpartum care in federally qualified health centers serving marginalized populations.

Methods: We abstracted electronic health record data from patients who received prenatal health care at three health centers in North Carolina to characterize quality postpartum care practices and to identify correlates of receiving quality care. We used multivariable log-binomial regression to estimate associations between patient, provider, and health center characteristics and two quality postpartum care outcomes: (1) timely care, defined as an initial assessment within the first 3 weeks and at least one additional visit within the first 3 months postpartum; and (2) comprehensive care, defined as receipt of services addressing family planning, infant feeding, chronic health, mood, and physical recovery across the first 3 months.

Results: In a cohort of 253 patients, 60.5% received comprehensive postpartum care and 30.8% received timely care. Several prenatal factors (adequate care use, an engaged patient–provider relationship) and postpartum factors (early appointment scheduling, exclusive breastfeeding, and use of enabling services) were associated with timely postpartum care. The most important correlate of comprehensive services was having more than one postpartum visit during the first 3 months postpartum.

Discussion: Identifying best practices for quality postpartum care in the health center setting can inform strategies to reduce health inequities. Future research should engage community stakeholders to define patient-centered measures of quality postpartum care and to identify community-centered ways of delivering this care.

A Systematic Review of Patient-, Provider-, and Health System-Level Predictors of Postpartum Health Care Use by People of Color and Low-Income and/or Uninsured Populations in the United States

Introduction: People of color and low-income and uninsured populations in the United States have elevated risks of adverse maternal health outcomes alongside low levels of postpartum visit attendance. The postpartum period is a critical window for delivering health care services to reduce health inequities and their transgenerational effects. Evidence is needed to identify predictors of postpartum visit attendance in marginalized populations. Methods: We conducted a systematic review of the peer-reviewed literature to identify studies that quantified patient-, provider-, and health system-level predictors of postpartum health care use by people of color and low-income and uninsured populations. We extracted study design, sample, measures, and outcome data from studies meeting our eligibility criteria, and used a modified Cochrane Risk of Bias tool to evaluate risk of bias. Results: Out of 2,757 studies, 36 met our criteria for inclusion in this review. Patient-level factors consistently associated with postpartum care included higher socioeconomic status, rural residence, fewer children, older age, medical complications, and previous health care use. Perceived discrimination during intrapartum care and trouble understanding the health care provider were associated with lower postpartum visit use, while satisfaction with the provider and having a provider familiar with one's health history were associated with higher use. Health system predictors included public facilities, group prenatal care, and services such as patient navigators and appointment reminders. Discussion: Postpartum health service research in marginalized populations has predominantly focused on patient-level factors; however, the multilevel predictors identified in this review reflect underlying inequities and should be used to inform the design of structural changes.

Spatial variation in access to the health care safety net for Hispanic immigrants, 1970-2017

Hispanic immigrants have long faced barriers to accessing health care in the U.S., as they are largely excluded from federal programs like Medicaid. Since the 1960s, the federal government has operated a nationwide network of Community Health Centers (CHCs) that serve anyone, regardless of ability to pay or citizenship status. To what extent has this widespread, immigrant-inclusive institution been accessible to Hispanic immigrants? Using novel administrative data joined with Census and American Community Survey data from 1970 to 2017, this study documents spatial variation in population-level proximity to CHCs in relation to changing Hispanic migration patterns. Findings show that health centers, both historically and contemporarily, have been far more spatially proximate to poor and foreign-born Hispanics than to poor whites. In 2017, 56% of poor and foreign-born Hispanics in the U.S. lived within two miles of a CHC compared to 30% of poor whites. While access to CHCs has been consistently greater in established gateways, regardless of urbanicity, growth in new destination safety net infrastructure has increased at a faster rate. The CHC program has been substantially more accessible to the foreign-born than U.S.-born Hispanic and uninsured populations, showing the geographic potential for CHCs to provide care to underserved immigrant communities. This study provides the first descriptive evidence of the programmatic reach of this safety net institution across time and space, highlighting a crucial yet underexplored factor in understanding the health of Hispanic immigrants.

Timing of Prenatal Care Initiation in the Health Resources and Services Administration Health Center Program in 2017

BACKGROUND

Early prenatal care is vital for improving maternal health outcomes and health behaviors, but medically vulnerable and underserved populations are less likely to begin prenatal care in the first trimester. In 2017, the Health Center Program provided safety-net care to more than 27 million persons, including 573 026 prenatal patients, at approximately 12 000 sites across the United States and U.S. jurisdictions. As part of a mandatory reporting requirement, health centers tracked whether patients initiated prenatal care in their first trimester of pregnancy.

OBJECTIVE

To identify health center characteristics associated with the initiation of prenatal care in the first trimester, as well as actionable steps policymakers, providers, and health centers can take to promote early initiation of prenatal care.

DESIGN

Secondary analysis of cross-sectional data from the 2017 Uniform Data System.

SETTING

The United States and 8 U.S. jurisdictions.

PARTICIPANTS

Health center grantees with prenatal patients (n = 1281).

MEASUREMENTS

Multinomial logistic regression (adjusted for state or jurisdiction clustering) was used to identify health center characteristics associated with achievement of the Healthy People 2020 baseline (77.1%) and target (84.8%) for women receiving prenatal care in the first trimester (Maternal, Infant, and Child Health Objective 10.1).

RESULTS

Overall, 57.4% of health centers met the Healthy People 2020 baseline (mean, 78%; median, 81%), and 37.9% met the Healthy People 2020 target. Several characteristics were positively associated with meeting the baseline (larger proportion of prenatal patients aged 20 to 24 years) and target (more total patients, prenatal care by referral only, a larger proportion of prenatal patients aged 25 to 44 or ≥45 years, and a larger proportion of White or privately insured patients). Other characteristics were negatively associated with the baseline (location outside New England, location in a rural area, and a large proportion of prenatal patients aged <15 years) and target (more prenatal patients, location outside New England, provision of prenatal care to women living with HIV, and more uninsured patients or patients eligible for both Medicare and Medicaid).

LIMITATION

The data set is at the health center grantee level and does not contain information on timing or quality of follow-up prenatal care.

CONCLUSION

Most health centers met the Healthy People 2020 baseline, but opportunities for improvement remain and the Healthy People 2020 target is still a challenge for many health centers. Policymakers, providers, and health centers can learn from high-achieving centers to promote early initiation of prenatal care among medically vulnerable and underserved populations.

Prenatal airshed pollutants and preterm birth in an observational birth cohort study in Detroit, Michigan, USA

Detroit, Michigan, currently has the highest preterm birth (PTB) rate of large cities in the United States. Disproportionate exposure to ambient air pollutants, including particulate matter ≤2.5 μm (PM_2.5), PM ≤ 10 μm (PM₁₀), nitrogen dioxide (NO₂) and benzene, toluene, ethylbenzene, and xylenes (BTEX) may contribute to PTB. Our objective was to examine the association of airshed pollutants with PTB in Detroit, MI. The Geospatial Determinants of Health Outcomes Consortium (GeoDHOC) study collected air pollution measurements at 68 sites in Detroit in September 2008 and June 2009. GeoDHOC data were coupled with 2008-2010 Michigan Air Sampling Network measurements in Detroit to develop monthly ambient air pollution estimates at a spatial density of 300 m². Using delivery records from two urban hospitals, we established a retrospective birth cohort of births by Detroit women occurring from June 2008 to May 2010. Estimates of air pollutant exposure throughout pregnancy were assigned to maternal address at delivery. Our analytic sample size included 7961 births; 891 (11.2%) were PTB. After covariate adjustment, PM₁₀ (P = 0.003) and BTEX (P < 0.001), but not PM_2.5 (P = 0.376) or NO₂ (P = 0.582), were statistically significantly associated with PTB. In adjusted models, for every 5-unit increase in PM₁₀ there was a 1.21 times higher odds of PTB (95% CI 1.07, 1.38) and for every 5-unit increase in BTEX there was a 1.54 times higher odds of PTB (95% CI 1.25, 1.89). Consistent with previous studies, higher PM₁₀ was associated with PTB. We also found novel evidence that higher airshed BTEX is associated with PTB. Future studies confirming these associations and examining direct measures of exposure are needed.

Trends in Preterm Delivery among Singleton Gestations with Critical Congenital Heart Disease

OBJECTIVE

To examine state-wide population trends in preterm delivery of children with critical congenital heart disease (CHD) over an 18-year period. We hypothesized that, coincident with early advancements in prenatal diagnosis, preterm delivery initially increased compared with the general population, and more recently has decreased.

STUDY DESIGN

Data from the Texas Public Use Data File 1999-2016 was used to evaluate annual percent preterm delivery (<37 weeks) in critical CHD (diagnoses requiring intervention at <1 year of age). We first evaluated for pattern change over time using joinpoint segmented regression. Trends in preterm delivery were then compared with all Texas livebirths. We then compared trends examining sociodemographic covariates including race/ethnicity, sex, and neighborhood poverty levels.

RESULTS

Of 7146 births with critical CHD, 1339 (18.7%) were delivered preterm. The rate of preterm birth increased from 1999 to 2004 (a mean increase of 1.69% per year) then decreased between 2005 and 2016 (a mean decrease of -0.41% per year). This represented a faster increase and then a similar decrease to that noted in the general population. Although the greatest proportion of preterm births occurred in newborns of Hispanic ethnicity and non-Hispanic black race, newborns with higher neighborhood poverty level had the most rapidly increasing rate of preterm delivery in the first era, and only a plateau rather than decrease in the latter era.

CONCLUSIONS

Rates of preterm birth for newborns with critical CHD in Texas first were increasing rapidly, then have been decreasing since 2005.

Cervical and colorectal cancer screening prevalence before and after Affordable Care Act Medicaid expansion

Community health centers (CHCs), which serve socioeconomically disadvantaged patients, experienced an increase in insured visits after the 2014 Affordable Care Act (ACA) coverage options began. Yet, little is known about how cancer screening rates changed post-ACA. Therefore, this study assessed changes in the prevalence of cervical and colorectal cancer screening from pre- to post-ACA in expansion and non-expansion states among patients seen in CHCs. Electronic health record data on 624,601 non-pregnant patients aged 21-64 eligible for cervical or colorectal cancer screening between 1/1/2012 and 12/31/2015 from 203 CHCs were analyzed. We assessed changes in prevalence and screening likelihood among patients, by insurance type and race/ethnicity and compared Medicaid expansion and non-expansion states using difference-in-difference methodology. Female patients had 19% increased odds of receiving cervical cancer screening post- relative to pre-ACA in expansion states [adjusted odds ratio (aOR) = 1.19, 95% confidence interval (CI) = 1.09-1.31] and 23% increased odds in non-expansion states (aOR = 1.23, 95% CI = 1.05-1.46): the greatest increase was among uninsured patients in expansion states (aOR = 1.36, 95% CI = 1.16-1.59) and privately-insured patients in non-expansion states (aOR = 1.43, 95% CI = 1.11-1.84). Colorectal cancer screening prevalence increased from 11% to 18% pre- to post-ACA in expansion states and from 13% to 21% in non-expansion states. For most outcomes, the observed changes were not significantly different between expansion and non-expansion states. Despite increased prevalences of cervical and colorectal cancer screening in both expansion and non-expansion states across all race/ethnicity groups, rates remained suboptimal for this population of socioeconomically disadvantaged patients.

Operational efficiency, patient composition and regional context of U.S. health centers: Associations with access to early prenatal care and low birth weight

Community health centers (CHCs) provide comprehensive medical services to medically under-served Americans, helping to reduce health disparities. This study aimed to identify the unique compositions and contexts of CHCs to better understand variation in access to early prenatal care and rates of low birth weights (LBW). Data include CHC-level data from the Uniform Data System, and regional-level data from the US Census American Community Survey and Behavioral Risk Factor Surveillance System. First, latent class analysis was conducted to identify unobserved subgroups of CHCs. Second, data envelopment analysis was performed to evaluate the operational efficiency of CHCs. Third, we used generalized linear models to examine the associations between the CHC subgroups, efficiency, and perinatal outcomes. Seven classes of CHCs were identified, including two rural classes, one suburban, one with large centers serving poor minorities in low poverty areas, and three urban classes. Many of these classes were characterized by the racial compositions of their patients. Findings indicate that CHCs serving white patients in rural areas have greater access to early prenatal care. Health centers with greater efficiency have lower rates of LBW, as do those who serve largely white patient populations in rural areas. CHCs serving poor racial minorities living in low-poverty areas had particularly low levels of access to early prenatal care and high rates of LBW. Findings highlight that significant diversity exists in the sociodemographic composition and regional context of US health centers, in ways that are associated with their operations, delivery of care, and health outcomes. Results from this study highlight that while the provision of early prenatal care and the efficiency with which a health center operates may improve the health of the women served by CHCs and their babies, the underlying social and economic conditions facing patients ultimately have a larger association with their health.

Maternal race/ethnicity as a risk factor for cervical insufficiency

BACKGROUND

Preterm birth (PTB) affects 1 in 9 pregnancies in the United States. There are well known but poorly understood racial/ethnic disparities in PTB rates. The role that racial/ethnic disparities in cervical insufficiency (CI) may play in the overall disparities in preterm birth rates is unknown.

OBJECTIVE

The primary objective of this study was to examine racial/ethnic differences in risk of CI.

STUDY DESIGN

We conducted a retrospective cohort study of singleton pregnant women in 2012 who were members of Kaiser Permanente Northern California (KPNC), excluding elective termination, delivery outside KPNC, and loss to follow-up. The primary outcome was CI; the secondary outcomes included stillbirth, PTB, and neonatal intensive care unit (NICU) admission. We compared rates of these outcomes among women of different racial/ethnic background. Multivariable logistic regression modeling was used to assess other potential risk factors for CI, including maternal age, parity, medical co-morbidities, prior cervical procedures, prior pregnancy terminations, and history of PTB.

RESULTS

A total of 34,173 women who were pregnant in 2012 were included in the study. The racial/ethnic makeup of the cohort was 38.6% White, 25.8% Asian, 25.1% Hispanic, 7% Black, and 3.5% other. Approximately 1% (401) of women were diagnosed with CI. Black women had a significantly higher rate of CI (3.2%) compared to White women (0.9%, P < 0.001) as well as higher rates of PTB (9.2%). Infants born to black women had higher rates of NICU care (8.7%) compared to other racial/ethnic groups. Regression analysis showed that Black race/ethnicity was significantly associated with CI compared to Whites (OR 2.89, 95% CI 2.13-3.92) after controlling for other variables associated with CI.

CONCLUSION

Black women had higher odds of CI compared to White women. This disparity may contribute to the significantly higher rate of PTB among Black women nationally. Further investigation of this association may provide important contributions to our understanding of both CI and PTB.

Effects of recruiting midwives into family physician program on the percentage of low birth weight (LBW) infants in rural areas of Kurdistan

Background: LBW is an important factor that can affect infant mortality and represents an index of economic and social development. It is expected that an increase in the density of midwives attending family physician programs will lead to a decrease in LBW in health centers. This study aimed to compare the percentage of LBW infants before and after the implementation of the family physician program in health centers with and without an increase in midwives density.

Methods: This cross-sectional study compared the percentage of LBW infants before and after the implementation of family physician programs in rural health centers with and without changes in midwives density in Kurdistan. In this study, we included 668 mothers of 2-month-old children and administered structured interviews in 2005 and 2013. Data were analyzed using the difference-indifferences and the Matchit statistical models.

Results: The Matchit model showed a significant average percentage increase 0.08 (0.006–0.17) in LBW infants born between 2005 and 2013 in health centers where the density of midwives increased compared with those where it remained unchanged. The difference-in-differences model showed that the odds ratio of LBW infants is increased by more than twice among participants who had a history of caesarean section.

Conclusion: The results of this study showed that an increase in the density of midwives in a family physician program did not have an impact on reducing the percentage of LBW infants born between 2005 and 2013, in health centers where the density of midwives augmented compared to those where it remained unaltered; it indicated that the increase in the density of midwives alone was not efficient. On the other hand, the results of our study show an increase in the risk of infants born at a LBW due to caesarean section. It is recommended that obstetricians and gynecologists must strictly control pregnancies and avoid unnecessary termination of pregnancy

Association between expansion of primary healthcare and racial inequalities in mortality amenable to primary care in Brazil: A national longitudinal analysis

BACKGROUND

Universal health coverage (UHC) can play an important role in achieving Sustainable Development Goal (SDG) 10, which addresses reducing inequalities, but little supporting evidence is available from low- and middle-income countries. Brazil's Estratégia de Saúde da Família (ESF) (family health strategy) is a community-based primary healthcare (PHC) programme that has been expanding since the 1990s and is the main platform for delivering UHC in the country. We evaluated whether expansion of the ESF was associated with differential reductions in mortality amenable to PHC between racial groups.

METHODS AND FINDINGS

Municipality-level longitudinal fixed-effects panel regressions were used to examine associations between ESF coverage and mortality from ambulatory-care-sensitive conditions (ACSCs) in black/pardo (mixed race) and white individuals over the period 2000-2013. Models were adjusted for socio-economic development and wider health system variables. Over the period 2000-2013, there were 281,877 and 318,030 ACSC deaths (after age standardisation) in the black/pardo and white groups, respectively, in the 1,622 municipalities studied. Age-standardised ACSC mortality fell from 93.3 to 57.9 per 100,000 population in the black/pardo group and from 75.7 to 49.2 per 100,000 population in the white group. ESF expansion (from 0% to 100%) was associated with a 15.4% (rate ratio [RR]: 0.846; 95% CI: 0.796-0.899) reduction in ACSC mortality in the black/pardo group compared with a 6.8% (RR: 0.932; 95% CI: 0.892-0.974) reduction in the white group (coefficients significantly different, p = 0.012). These differential benefits were driven by greater reductions in mortality from infectious diseases, nutritional deficiencies and anaemia, diabetes, and cardiovascular disease in the black/pardo group. Although the analysis is ecological, sensitivity analyses suggest that over 30% of black/pardo deaths would have to be incorrectly coded for the results to be invalid. This study is limited by the use of municipal-aggregate data, which precludes individual-level inference. Omitted variable bias, where factors associated with ESF expansion are also associated with changes in mortality rates, may have influenced our findings, although sensitivity analyses show the robustness of the findings to pre-ESF trends and the inclusion of other municipal-level factors that could be associated with coverage.

CONCLUSIONS

PHC expansion is associated with reductions in racial group inequalities in mortality in Brazil. These findings highlight the importance of investment in PHC to achieve the SDGs aimed at improving health and reducing inequalities.

The interplay of race, socioeconomic status and neighborhood residence upon birth outcomes in a high black infant mortality community

This study examined the interrelationship of race and socioeconomic status (SES) upon infant birthweight at the individual and neighborhood levels within a Midwestern US county marked by high Black infant mortality. The study conducted a multi-level analysis utilizing individual birth records and census tract datasets from 2010, linked through a spatial join with ArcGIS 10.0. The maternal population of 2861 Black and White women delivering infants in 2010, residing in 57 census tracts within the county, constituted the study samples. The main outcome was infant birthweight. The predictors, race and SES were dichotomized into Black and White, low-SES and higher-SES, at both the individual and census tract levels. A two-part Bayesian model demonstrated that individual-level race and SES were more influential birthweight predictors than community-level factors. Specifically, Black women had 1.6 higher odds of delivering a low birthweight (LBW) infant than White women, and low-SES women had 1.7 higher odds of delivering a LBW infant than higher-SES women. Moderate support was found for a three-way interaction between individual-level race, SES and community-level race, such that Black women achieved equity with White women (4.0% Black LBW and 4.1% White LBW) when they each had higher-SES and lived in a racially congruous neighborhood (e.g., Black women lived in disproportionately Black neighborhood and White women lived in disproportionately White neighborhood). In sharp contrast, Black women with higher-SES who lived in a racially incongruous neighborhood (e.g., disproportionately White) had the worst outcomes (14.5% LBW). Demonstrating the layered influence of personal and community circumstances upon health, in a community with substantial racial disparities, personal race and SES independently contribute to birth outcomes, while environmental context, specifically neighborhood racial congruity, is associated with mitigated health risk.

Maternal Race/Ethnicity and Predictors of Pregnancy and Infant Outcomes

Objective. To examine predictors of pregnancy and infant outcomes, including maternal race/ethnicity. Design. Prospective and observational follow-up of high-risk pregnancies and births. Participants. Three hundred fifty-four mothers and their preterm and/or high-risk live-born neonates were closely followed in three tertiary care centers from the prenatal to postnatal periods for potential high-risk and/or preterm births that required neonatal resuscitations. Major Outcome Measures. Pregnancy complications, birth complications, and infant outcomes were examined in conjunction with maternal factors, including preexisting health problems, health behaviors (smoking, alcohol consumption, prenatal visits), and the birth setting (tertiary care centers or community hospitals). Results. About 22% of these infants were transferred into the tertiary care centers from the community hospitals right after birth; the rest were born in the centers. According to regression analyses, predictors of the birth setting were race (White vs. non-White), maternal health behaviors, pregnancy complications, fetal distress, and the presence of congenital defects for infants (p < .001). Predictors for fetal distress included race (Whites) and pregnancy-induced hypertension (p < .003). Predictors for lower birth weight included race (non-Whites), maternal cigarette smoking, pregnancy complications, fetal distress, and congenital defects (p < .001). Infant mortality rate was 3.9% for these high-risk infants, with the highest rate in infants born to Black mothers (8%). Conclusions. There are obvious health disparities among White and non-White women experiencing high-risk pregnancies and births. Future studies are needed to develop interventions targeted to different racial/ethnic groups during pregnancy to reduce preterm and high-risk births.

The Roles of Counseling Psychologists in Reducing Health Disparities

This article presents an overview of the health disparities problem that exists among individuals from ethnic minority and low-income backgrounds and their majority counterparts. The argument is made that the involvement of counseling psychologists in addressing this health disparities problem presents an opportunity for the field to remain true to its commitment to prevention, multiculturalism, and social justice while becoming more competitive in the health care and health promotion fields. This article highlights the prevalence of health disparities and identifies the primary factors contributing to these disparities. In addition, the roles and approaches that counseling psychologists can adopt to help alleviate this problem are specified.

Quantifying the Health Benefits of Primary Care Physician Supply in the United States

This analysis addresses the question, Would increasing the number of primary care physicians improve health outcomes in the United States? A search of the PubMed database for articles containing “primary care physician supply” or “primary care supply” in the title, published between 1985 and 2005, identified 17 studies, and 10 met all inclusion criteria. Results were reanalyzed to assess primary care effect size and the predicted effect on health outcomes of a one-unit increase in primary care physicians per 10,000 population. Primary care physician supply was associated with improved health outcomes, including all-cause, cancer, heart disease, stroke, and infant mortality; low birth weight; life expectancy; and self-rated health. This relationship held regardless of the year (1980–1995) or level of analysis (state, county, metropolitan statistical area (MSA), and non-MSA levels). Pooled results for all-cause mortality suggest that an increase of one primary care physician per 10,000 population was associated with an average mortality reduction of 5.3 percent, or 49 per 100,000 per year.

Exposure to Pre- and Perinatal Risk Factors Partially Explains Mean Differences in Self-Regulation between Races

OBJECTIVES

To examine whether differential exposure to pre- and perinatal risk factors explained differences in levels of self-regulation between children of different races (White, Black, Hispanic, Asian, and Other).

METHODS

Multiple regression models based on data from the Early Childhood Longitudinal Study, Birth Cohort (n ≈ 9,850) were used to analyze the impact of pre- and perinatal risk factors on the development of self-regulation at age 2 years.

RESULTS

Racial differences in levels of self-regulation were observed. Racial differences were also observed for 9 of the 12 pre-/perinatal risk factors. Multiple regression analyses revealed that a portion of the racial differences in self-regulation was explained by differential exposure to several of the pre-/perinatal risk factors. Specifically, maternal age at childbirth, gestational timing, and the family's socioeconomic status were significantly related to the child's level of self-regulation. These factors accounted for a statistically significant portion of the racial differences observed in self-regulation.

CONCLUSIONS

The findings indicate racial differences in self-regulation may be, at least partially, explained by racial differences in exposure to pre- and perinatal risk factors.

The War on Poverty's Experiment in Public Medicine: Community Health Centers and the Mortality of Older Americans

This paper uses the rollout of the first Community Health Centers (CHCs) to study the longer-term health effects of increasing access to primary care. Within ten years, CHCs are associated with a reduction in age-adjusted mortality rates of 2 percent among those 50 and older. The implied 7 to 13 percent decrease in one-year mortality risk among beneficiaries amounts to 20 to 40 percent of the 1966 poor/non-poor mortality gap for this age group. Large effects for those 65 and older suggest that increased access to primary care has longer-term benefits, even for populations with near universal health insurance. (JEL H75, I12, I13, I18, I32, I38, J14).

Policy dilemmas in Latino health care and implementation of the Affordable Care Act

The changing Latino demographic in the United States presents a number of challenges to health care policy makers, clinicians, organizations, and other stakeholders. Studies have demonstrated that Latinos tend to have worse patterns of access to, and utilization of, health care than other ethnic and racial groups. The implementation of the Affordable Care Act (ACA) of 2010 may ameliorate some of these disparities. However, even with the ACA, it is expected that Latinos will continue to have problems accessing and using high-quality health care, especially in states that are not expanding Medicaid eligibility as provided by the ACA. We identify four current policy dilemmas relevant to Latinos' health and ACA implementation: (a) the need to extend coverage to the undocumented; (b) the growth of Latino populations in states with limited insurance expansion;

Racial disparities in outcomes of twin pregnancies: elective cesarean or trial of labor?

OBJECTIVE

The objective of the study was to determine the relationships between maternal race and obstetric outcomes in twin gestations by planned mode of delivery.

STUDY DESIGN

We performed a secondary analysis of the Consortium on Safe Labor data. Patients with twin gestations in vertex-vertex presentation greater than 32 weeks' gestational age were grouped according to race. Demographic information and neonatal and maternal outcomes were analyzed according to planned mode of delivery: elective cesarean or trial of labor (with subsequent vaginal delivery, unplanned cesarean, or combined delivery). The primary outcome was unplanned cesarean. Secondary outcomes included maternal and neonatal outcomes.

RESULTS

One thousand nine vertex-vertex twin pregnancies were identified. There were no significant differences across ethnicities in the rate of unplanned cesarean delivery, which occurred in 233 of patients undergoing trial of labor (27%). Elective cesarean occurred in 151 patients (15%). African American women were less likely to have an elective cesarean compared with whites (odds ratio, 0.5; 95% confidence interval, 0.3-0.8), and Asian women were more likely to have an elective cesarean compared with whites (odds ratio, 2.0; 95% confidence interval, 1.2-3.4. Combined delivery occurred in 67 patients (8%) and did not differ among the groups. Subgroup analysis did not reveal any significant differences in neonatal outcomes. Adverse maternal outcomes were rare across ethnicities.

CONCLUSION

Unplanned cesarean delivery rates are similar in twin pregnancies, regardless of race. Maternal and neonatal outcomes in twin gestations are similar across ethnicities, regardless of mode of delivery.

Exploring contextual factors and patient activation: evidence from a nationally representative sample of patients with depression

Patient activation has been considered as a "blockbuster drug of the century." Patients with mental disorders are less activated compared to patients with other chronic diseases. Low activation due to mental disorders can affect the efficiency of treatment of other comorbidities. Contextual factors are significantly associated with mental health care access and utilization. However, evidence of their association with patient activation is still lacking. Using data from the Health Tracking Household Survey 2007 and Area Health Resource File 2008, we examine the association between contextual factors and self-reported activation levels among patients with depression. We investigate two types of contextual factors--(a) site of usual source of care and (b) community characteristics, measured by mental health care resources availability, population demographics, and socioeconomic characteristics at the county level. Results show significant variation in activation levels by contextual factors. The availability of community mental health centers, lower proportion of foreign-born individuals, and higher income in the local community are associated with higher patient activation. Our results also show that depressed patients having a usual source of care at a physician's office have significantly higher patient activation levels than those with a usual source of care in the emergency department or hospital outpatient clinics. Results suggest that primary care setting is critical to having a sustained relationship between patients and physicians in order to enhance patient engagement in mental health care. Interventions in communities with low income and high immigrant populations are necessary.

Does the CenteringPregnancy group prenatal care program reduce preterm birth? The conclusions are premature

Prenatal care is promoted as a means to a healthy pregnancy outcome. In the United States great resources have been spent to expand the availability of a program of prenatal care, but without evidence for its effectiveness in the general population. Despite greater access to prenatal care over the last several decades, there has been no improvement in obstetric outcomes, such as preterm delivery. The CenteringPregnancy program of group prenatal visits is a novel form of prenatal care that, according to several studies, has been said to improve satisfaction with prenatal visits and with pregnancy outcomes. A careful reading of the studies shows that those goals are yet to be achieved. Innovation is welcome and essential, but larger studies are needed to achieve statistical significance to demonstrate improved outcome.

Nurse-midwives in federally funded health centers: understanding federal program requirements and benefits

Midwives are working in federally funded health centers in increasing numbers. Health centers provide primary and preventive health care to almost 20 million people and are located in every US state and territory. While health centers serve the entire community, they also serve as a safety net for low-income and uninsured individuals. In 2010, 93% of health center patients had incomes below 200% of the Federal Poverty Guidelines, and 38% were uninsured. Health centers, including community health centers, migrant health centers, health care for the homeless programs, and public housing primary care programs, receive grant funding and enjoy other benefits due to status as federal grantees and designation as federally qualified health centers. Clinicians working in health centers are also eligible for financial and professional benefits because of their willingness to serve vulnerable populations and work in underserved areas. Midwives, midwifery students, and faculty working in, or interacting with, health centers need to be aware of the regulations that health centers must comply with in order to qualify for and maintain federal funding. This article provides an overview of health center regulations and policies affecting midwives, including health center program requirements, scope of project policy, provider credentialing and privileging, Federal Tort Claims Act malpractice coverage, the 340B Drug Pricing Program, and National Health Service Corps scholarship and loan repayment programs.

Clinical quality performance in U.S. health centers

OBJECTIVE

To describe current clinical quality among the nation's community health centers and to examine health center characteristics associated with performance excellence.

DATA SOURCES

National data from the 2009 Uniform Data System.

DATA COLLECTION/EXTRACTION METHODS

Health centers reviewed patient records and reported aggregate data to the Uniform Data System.

STUDY DESIGN

Six measures were examined: first-trimester prenatal care, childhood immunization completion, Pap tests, low birth weight, controlled hypertension, and controlled diabetes. The top 25 percent performing centers were compared with lower performing (bottom 75 percent) centers on these measures. Logistic regressions were utilized to assess the impact of patient, provider, and institutional characteristics on health center performance.

PRINCIPAL FINDINGS

Clinical care and outcomes among health centers were generally comparable to national averages. For instance, 67 percent of pregnant patients received timely prenatal care (national = 68 percent), 69 percent of children achieved immunization completion (national = 67 percent), and 63 percent of hypertensive patients had blood pressure under control (national = 48 percent). Depending on the measure, centers with more uninsured patients were less likely to do well, while centers with more physicians and enabling service providers were more likely to do well.

CONCLUSIONS

Health centers provide quality care at rates comparable to national averages. Performance may be improved by increasing insurance coverage among patients and increasing the ratios of physicians and enabling service providers to patients.

Paths to success: optimal and equitable health outcomes for all

Abstract:U.S. health disparities are real, pervasive, and persistent, despite dramatic improvements in civil rights and economic opportunity for racial and ethnic minority and lower socioeconomic groups in the United States. Change is possible, however. Disparities vary widely from one community to another, suggesting that they are not inevitable. Some communities even show paradoxically good outcomes and relative health equity despite significant social inequities. A few communities have even improved from high disparities to more equitable and optimal health outcomes. These positive-deviance communities show that disparities can be overcome and that health equity is achievable. Research must shift from defining the problem (including causes and risk factors) to testing effective interventions, informed by the natural experiments of what has worked in communities that are already moving toward health equity. At the local level, we need multi-dimensional interventions designed in partnership with communities and continuously improved by rapid-cycle surveillance feedback loops of community-level disparities metrics. Similarly coordinated strategies are needed at state and national levels to take success to scale. We propose ten specific steps to follow on a health equity path toward optimal and equitable health outcomes for all Americans.

A modified measure of health care disparities applied to birth weight disparities and subsequent mortality

We describe how a modified Gini index serves as an improved method of estimating health care disparities. The method, although general, is applied to an example of birth weight disparities and to their effect on subsequent mortality. The method provides the between-group results obtainable from current methods (i.e. how Hispanics generally fare relative to non-Hispanic Whites) but adds measures of within-group disparities (i.e. which specific Hispanics experience the greatest disparate treatment). Our application to birth weights and receipt of prenatal care, which may provide an upper bound because of omitted variables, shows that the time-of-birth disparities are associated with increased infant mortality within the first year of life.

The impact of primary care: a focused review

Primary care serves as the cornerstone in a strong healthcare system. However, it has long been overlooked in the United States (USA), and an imbalance between specialty and primary care exists. The objective of this focused review paper is to identify research evidence on the value of primary care both in the USA and internationally, focusing on the importance of effective primary care services in delivering quality healthcare, improving health outcomes, and reducing disparities. Literature searches were performed in PubMed as well as "snowballing" based on the bibliographies of the retrieved articles. The areas reviewed included primary care definitions, primary care measurement, primary care practice, primary care and health, primary care and quality, primary care and cost, primary care and equity, primary care and health centers, and primary care and healthcare reform. In both developed and developing countries, primary care has been demonstrated to be associated with enhanced access to healthcare services, better health outcomes, and a decrease in hospitalization and use of emergency department visits. Primary care can also help counteract the negative impact of poor economic conditions on health.

Screening tests during prenatal care: does practice follow the evidence?

To examine whether the frequency of four screening tests during prenatal care conforms to evidence of effectiveness. We estimated rates of urine culture, anemia screening, oral glucose tolerance test (OGTT), and urinalysis during prenatal care. To do this, we used national probability samples of office visits to physicians (National Ambulatory Medical Care Survey) and to hospital outpatient departments (National Hospital Ambulatory Medical Care Survey) from 2001 to 2006. We compare observed rates to recommendations from the U.S. Preventive Services Task Force (USPSTF). On average, women received a urine culture in less than half of pregnancies. Women received just over one anemia screening on average per pregnancy. From 2001-2003, women received an average of 5.6 urinalyses per pregnancy; the average dropped to 4.3 urinalyses per pregnancy in 2004-2006. On average, women received just under one OGTT per pregnancy. Minorities and older women tend to get more anemia screenings, urine cultures, and OGTTs than white women and younger women. Compared to USPSTF recommendations, too few women are receiving a urine culture during prenatal care. In contrast, women receive far too many urinalyses, but the rate appears to be falling. Anemia screening conforms closely to recommendations. The USPSTF does not recommend for or against universal diabetes screening using OGTT. Women appear to receive OGTT routinely.

Comparison of primary care experiences among adults in general outpatient clinics and private general practice clinics in Hong Kong

Background

The main goal of Hong Kong's publicly-funded general outpatient clinics (GOPCs) is to provide primary medical services for the financially vulnerable. The objective of the current study was to compare the primary care experiences of GOPC users and the users of care provided by private general practitioners (GPs) in Hong Kong via a territory-wide telephone survey.

Methods

One thousand adults in Hong Kong aged 18 and above were interviewed by a telephone survey. The modified Chinese translated Primary Care Assessment Tool was used to collect data on respondents' primary care experience.

Results

Our results indicated that services provided by GOPC were more often used by female, older, poorer, chronically-ill and less educated population. GOPC participants were also more likely to have visited a specialist or used specialist services (69.7% vs. 52.0%; p < 0.001), although this difference in utilization of specialist services disappeared after adjusting for age (55.7% vs. 52.0%, p = 0.198). Analyses were also performed to asses the relationship between healthcare settings (GOPCs versus private GPs) and primary care quality. Private GP patients achieved higher overall PCAT scores largely due to better accessibility (Mean: 6.88 vs. 8.41, p < 0.001) and person-focused care (Mean: 8.37 vs. 11.69, p < 0.001).

Conclusions

Our results showed that patients primarily receiving care from private GPs in Hong Kong reported better primary care experiences than those primarily receiving care from GOPCs. This was largely due to the greater accessibility and better interpersonal relationships offered by the private GPs. As most patients use both GOPCs and private GPs, their overall primary care experiences may not be as different as the findings of this study imply.

Predictors of timely follow-up after abnormal cancer screening among women seeking care at urban community health centers

BACKGROUND

We sought to measure time and identify predictors of timely follow-up among a cohort of racially/ethnically diverse inner city women with breast and cervical cancer screening abnormalities.

METHODS

Eligible women had an abnormality detected on a mammogram or Papanicolaou (Pap) test between January 2004 and December 2005 in 1 of 6 community health centers in Boston, Massachusetts. Retrospective chart review allowed us to measure time to diagnostic resolution. We used Cox proportional hazards models to develop predictive models for timely resolution (defined as definitive diagnostic services completed within 180 days from index abnormality).

RESULTS

Among 523 women with mammography abnormalities and 474 women with Pap test abnormalities, >90% achieved diagnostic resolution within 12 months. Median time to resolution was longer for Pap test than for mammography abnormalities (85 vs 27 days). Site of care, rather than any sociodemographic characteristic of individuals, including race/ethnicity, was the only significant predictor of timely follow-up for both mammogram and Pap test abnormalities.

CONCLUSIONS

Site-specific community-based interventions may be the most effective interventions to reduce cancer health disparities when addressing the needs of underserved populations.

Secular trends in excess fetal and infant mortality using perinatal periods of risk analysis

Perinatal periods of risk (PPOR) provide an alternative analytical approach to studying infant mortality. Results can be used to focus community activities to improve infant and maternal health. This article demonstrates the use of PPOR to monitor trends in excess fetal and infant mortality related to disparities associated with race and ethnicity in Kansas City, MO (KC). Based on a comparison of PPOR analyses for 1996-2000 and 2001-2005, there was a 30% reduction in excess fetal and infant mortality in Kansas City and reductions for both non-Hispanic blacks (17%) and non-Hispanic whites (66.7%). However, the disparity ratio for excess mortality rates between non-Hispanic blacks and non-Hispanic whites nearly doubled. Prematurity, the most frequent cause of infant mortality in Kansas City during 2001-2005 accounted for 42.5% of the infant deaths. Being a teenage mother; having less than a high-school education; being unmarried; having an unintended pregnancy; being obese preconceptually; being diabetic; using substances such as tobacco or drugs during pregnancy; receiving late, inadequate or intermediate amounts of prenatal care; having a multifetal pregnancy; having a primary elective cesarean section; delivering a preterm infant or having a male infant; and being enrolled in Medicaid all increased the risk of infant death.

Health status and birth outcomes among pregnant women in substance abuse treatment

PURPOSE

We sought to examine the physical and mental health status and low birthweight and preterm birth among low-income pregnant women in substance abuse treatment.

METHODS

A prospective correlational design was used with 84 pregnant women enrolled in a university-affiliated, comprehensive, hospital-based substance abuse treatment program. The majority of the sample reported heroin as their primary substance of abuse.

RESULTS

Approximately 39% of the infants were born preterm and 27.5% were low birthweight. Poorer perception of current health, cocaine as the primary substance of abuse, and number of prior substance abuse treatment admissions were independently associated with preterm birth. Being African American and a poorer perception of current health were independently associated with low birthweight.

CONCLUSION

Asking about perceptions of their current health is a useful addition to comprehensive assessment for pregnant women with substance abuse problems in any setting. Further knowledge of women's physical and mental health status will improve identification of those who are at even greater risk in a group at high risk overall.

One size does not fit all: an examination of low birthweight disparities among a diverse set of racial/ethnic groups

To examine disparities in low birthweight using a diverse set of racial/ethnic categories and a nationally representative sample. This research explored the degree to which sociodemographic characteristics, health care access, maternal health status, and health behaviors influence birthweight disparities among seven racial/ethnic groups. Binary logistic regression models were estimated using a nationally representative sample of singleton, normal for gestational age births from 2001 using the ECLS-B, which has an approximate sample size of 7,800 infants. The multiple variable models examine disparities in low birthweight (LBW) for seven racial/ethnic groups, including non-Hispanic white, non-Hispanic black, U.S.-born Mexican-origin Hispanic, foreign-born Mexican-origin Hispanic, other Hispanic, Native American, and Asian mothers. Race-stratified logistic regression models were also examined. In the full sample models, only non-Hispanic black mothers have a LBW disadvantage compared to non-Hispanic white mothers. Maternal WIC usage was protective against LBW in the full models. No prenatal care and adequate plus prenatal care increase the odds of LBW. In the race-stratified models, prenatal care adequacy and high maternal health risks are the only variables that influence LBW for all racial/ethnic groups. The race-stratified models highlight the different mechanism important across the racial/ethnic groups in determining LBW. Differences in the distribution of maternal sociodemographic, health care access, health status, and behavior characteristics by race/ethnicity demonstrate that a single empirical framework may distort associations with LBW for certain racial and ethnic groups. More attention must be given to the specific mechanisms linking maternal risk factors to poor birth outcomes for specific racial/ethnic groups.

Trends in mental health and substance abuse services at the nation's community health centers: 1998-2003

OBJECTIVE

We examined trends in delivery of mental health and substance abuse services at the nation's community health centers.

METHODS

Analyses used data from the Health Resources and Services Administration (HRSA), Bureau of Primary Care's (BPHC) 1998 and 2003 Uniform Data System, merged with county-level data.

RESULTS

Between 1998 and 2003, the number of patients diagnosed with a mental health/substance abuse disorder in community health centers increased from 210,000 to 800,000. There was an increase in the number of patients per specialty mental health/substance abuse treatment provider and a decline in the mean number of patient visits, from 7.3 visits per patient to 3.5 by 2003. Although most community health centers had some on-site mental health/substance abuse services, centers without on-site services were more likely to be located in counties with fewer mental health/substance abuse clinicians, psychiatric emergency rooms, and inpatient hospitals.

CONCLUSIONS

Community health centers are playing an increasingly central role in providing mental health/substance abuse treatment services in the United States. It is critical both to ensure that these centers have adequate resources for providing mental health/substance abuse care and that they develop effective linkages with mental health/substance abuse clinicians in the communities they serve.

Health insurance and access to care for families with young children in California, 2001-2005: differences by immigration status

OBJECTIVES

To examine differences and trends in health insurance coverage and access to care for California families by immigration status.

METHODS

Cross-sectional data on 37,236 families with young children <18 years of age from the 2001, 2003 and 2005 California Health Interview Survey are used to assess trends in health insurance and access to care for children and their parents by four immigration dyads: (1) both are Citizens; (2) child is a legal resident/citizen, and parent is legal resident (Documented); (3) child is a citizen, and parent is undocumented (Mixed); and (4) both are Undocumented.

RESULTS

Before and after adjustment for covariates, only children in Undocumented dyads were less likely than Citizen dyads to have insurance (OR = 0.20, CI: 0.16-0.26) and all three measures of access: physician visits (OR = 0.69, CI: 0.52-0.91), dental visits (OR = 0.47, CI: 0.35-0.63), and a regular source of care (OR = 0.51, CI: 0.37-0.69). Parents in all non-Citizen dyads had poorer access than Citizen dyads across all measures, with the exception of dental visits and a regular source for parents in Documented dyads. Children of all dyads except Citizens were more likely to be insured in 2005 vs. 2001. The largest gain was for undocumented dyad children with 2.77 times higher odds (CI: 1.62-4.75) of being insured in 2005 vs. 2001. All children dyads except Mixed were also more likely to have a physician visit. For parents, there was only a decrease in insurance coverage for Citizen dyads (OR = 0.79, CI: 0.67-0.93) and few changes in access. Conclusions While there were relatively few disparities and some improvements in insurance coverage and access for children in California (except for undocumented children), concomitant changes for parents were not observed. Without attention to the family in health care reforms, disparities may not fully resolve for children and may continue or even increase for parents.

The perceived financial impact of quality improvement efforts in community health centers

We administered surveys to 100 chief executive officers (CEOs) of community health centers to determine their perceptions of the financial impact of the Health Disparities Collaboratives, a national quality improvement initiative. One third of the CEOs believed that the HDC had a negative financial impact on their health center, and this perception was significantly correlated with centers having a higher proportion of uninsured patients. Performance-based payment incentives may improve care but may also add new financial burdens to facilities that treat the uninsured population. As such, a provider's payer mix may need to be considered in the design of QI programs if they are to be sustainable.

Racial and ethnic disparities in the quality of asthma care

Racial and ethnic disparities in the quality of asthma care have been well documented in the United States. There are multiple factors associated with such disparities in asthma care, including structural barriers (eg, ability to access the health-care system), process-of-care barriers (eg, ability to navigate the health-care system), and process-of-care barriers at the interpersonal level (eg, ability to work effectively with a health-care provider) for equitable, quality asthma care. This article summarizes these issues and identifies specific areas for future investigation. At a health-systems level, further work is needed to understand how medical care financing arrangements may or may not be contributing to racial and ethnic disparities in asthma care, as well as how specific organizational initiatives can address these issues. Research needs at the patient/provider level include defining the content and methods for disseminating issues regarding cultural competency to health-care providers.

Welfare, Work, and Health Care Access Predictors of Low-Income Children's Physical Health Outcomes

This analysis examines whether young children's (N= 494) general physical health is associated with parental employment, welfare receipt, and health care access within a low-income population transitioning from welfare to work. A latent physical health measure derived from survey and medical chart data is used to capture children's poor health, and parental ratings of child health are used to identify excellent health. Controlling for a host of factors associated with children's health outcomes, results show that children of caregivers who are unemployed and off welfare have better health than children of caregivers who are working and off welfare. Children whose caregivers are unemployed and on welfare, or combining work and welfare, have health outcomes similar to children of caregivers who are working and off welfare. Health care access characteristics, such as gaps in health insurance coverage, source of primary care setting, and type of health insurance are associated with children's general physical health. Implications of these results for state TANF programs are discussed.

Health center financial performance: national trends and state variation, 1998-2004

For four decades, health centers have provided quality, cost-effective primary healthcare to underserved populations. Using the Uniform Data System, this study analyzes national trends in health center patients, providers, and financial performance for 1998-2004, and state-specific data for 2004. Between 1998 and 2004, health centers served increasing numbers of underserved patients, which included patients who were uninsured or on Medicaid, minorities, and patients at or below poverty level. Even though the number of health center providers and patients increased, patient-to-provider ratios did not change significantly. Medicaid remained the single largest source of health center revenue, accounting for 36.4 percent of total revenue in 2004. Compared with Medicare, private insurance, and self-pay, Medicaid consistently reimbursed health centers at the highest rate per patient. Federal and nonfederal grants to support care for the uninsured as well as enabling services such as transportation, translation, and other support systems is one of many important sources of revenue. Financial challenges for health centers included increasing costs and varied or declining rates of reimbursement for services rendered. However, health centers became more self-sufficient over time, average net revenues increased, and operating margins were predominantly positive. Data on individual states, with different numbers and types of health centers, varied widely in all of these categories. In conclusion, health centers rely on federal and nonfederal grant support in concert with the Medicaid program as major funding sources and continued financial stability will be contingent upon health centers' ability to balance revenues with the cost of managing the vulnerable populations that they serve.

Access to care for U.S. health center patients and patients nationally: how do the most vulnerable populations fare?

This study examined access to care for uninsured and Medicaid-insured community health center patients in comparison to nonhealth center patients nationally. Using nationally representative data from 2 major surveys in 2002, there was a positive association between seeking care in community health centers and self-reported access to care for both uninsured and Medicaid patients. This suggests that health centers may fill a critical gap in access to care for patients who use their services. Given recent budget cuts to the Medicaid program, health centers remain an important policy option to assure access to care for vulnerable populations.
