Overweight/obesity and weight-related treatment among patients in U.S. federally supported health centers.

BACKGROUND: We obtained the prevalence of overweight/obesity, weight-loss attempts, and weight-related counseling and treatment among U.S. adults who sought care in federally funded community health centers. We investigated whether racial/ethnic and gender disparities existed for these measures. METHODS: Data came from the 2009 Health Center Patient Survey. Measures included body mass index (BMI), self-perceived weight, weight-loss attempts, being told of a weight problem, receipt of weight-related counseling, nutritionist referrals, weight-loss prescriptions, and cholesterol checks. We conducted bivariate analyses to determine distributions by race/ethnicity and gender, then ran logistic regressions to examine the effects of several sociodemographic factors on weight-loss attempts and on being told of a weight problem. RESULTS: Overall, 76% of adult patients seen in health centers were overweight or obese (BMI ≥ 25.0 kg/m(2)); 55% of overweight patients, and 87% of obese patients correctly perceived themselves as overweight. There were no racial/ethnic differences in BMI categories or self-perceptions of weight. Females were more likely than males to be obese and also more likely to perceive themselves as overweight. About 60% of overweight/obese patients reported trying to lose weight in the past year. There were no racial/ethnic disparities favoring non-Hispanic White patients in weight-related treatment. Women were more likely than men to receive referrals to a nutritionist or weight-loss prescriptions. Overweight/obese patients had higher adjusted odds of a past-year weight-loss attempt if they perceived themselves as overweight (OR = 3.30, p < 0.0001), were female (OR = 1.95, p < 0.05), African American (OR = 3.34, p < 0.05), or Hispanic/Latino (OR = 2.14, p < 0.05). Overweight/obese patients had higher odds of being told they had a weight problem if they were Hispanic/Latino (OR = 2.56, p < 0.05) or if they had two or more chronic conditions (OR = 2.77, p < 0.01). CONCLUSIONS: Patients seen in community health centers have high rates of overweight and obesity, even higher than the general U.S. population. Efforts to address weight problems during primary care visits are needed to reduce the burden of obesity and its sequellae among health center patients.

Racial/ethnic differences in clinical quality performance among health centers.

More than 1100 federally funded health centers provide primary and preventive care to about 20 million underserved patients in the United States. Since 2008, the Health Resources and Services Administration has implemented a clinical quality improvement initiative to measure and evaluate the quality of care across all health centers. We assessed racial/ethnic disparities in clinical quality among US health centers, and examined whether performance on quality measures varied across 3 health center characteristics. National data came from the 2009 Uniform Data System. We examined performance across 3 indicators of clinical quality: poorly controlled hypertension among adult patients, poorly controlled diabetes among adult patients, and low birth weight among newborns. We compared results for each measure across racial/ethnic groups, as well as across 3 health center characteristics: health center patient volume, duration of health center funding, and extent of managed care penetration. Non-Hispanic Asian patients had the best results among racial/ethnic groups for 2 of the 3 measures examined: lowest rates of poorly controlled diabetes (26%) and hypertension (34%). Hispanics/Latinos had similar rates of poor hypertension control compared with non-Hispanic whites (38% for both), and lower rates of low birth weight (8% vs 10%). Poor diabetes control was more prevalent among Hispanic/Latino patients than non-Hispanic white patients, but the absolute difference was small (5 percentage points). Non-Hispanic black/African American patients had statistically worse outcomes than non-Hispanic white patients, but the absolute differences were also small (2-6 percentage points, depending on outcome). Health centers with larger patient volume fared better than their counterparts with smaller volume for all racial/ethnic groups. For Hispanic/Latino patients, more established health centers compared favorably to new health centers for all 3 outcomes. Health centers with some managed care penetration did better for diabetes and hypertension control relative to health centers without managed care penetration. Compared with national rates, health centers report minimal racial/ethnic disparities in clinical outcomes. Health center characteristics are also associated with clinical outcomes. More research is needed to determine the nature of disparities after accounting for health center patient, provider, and institutional characteristics.

Development of the Chinese primary care assessment tool: data quality and measurement properties.

OBJECTIVE: The aim of this study was to translate and adapt the Primary Care Assessment Tool to assess the perceptions of the quality of primary care among patients in China and to examine the psychometric properties of the adapted Primary Care Assessment Tool Chinese version (PCAT-C). DESIGN: A cross-sectional survey to assess the validity and reliability of PCAT-C using standard psychometric techniques. SETTING: Outpatient departments of five state-level and provincial-level hospitals and four municipal-level hospitals as well as nine community health centers in Changsha, China. PARTICIPANTS: A total of 2532 patients visiting primary care providers. RESULTS: The PCAT-C was acceptable to patients, as evidenced by low proportions of missing data and a full range of possible scores for all items. Two items were eliminated following principal component analysis and reliability testing. The principal component analysis extracted eight multiple-item scales and one single-item scale. Multiple-item scales had reasonable internal consistency and high item-scale correlations. CONCLUSIONS: This study represents the first attempt to construct an instrument for assessing patient reports on the quality of primary care, which is applicable to the Chinese context. Psychometric assessments indicated that the PCAT-C is a useful instrument for assessing the core attributes of primary care in China.

Primary care and public health activities in select US health centers: documenting successes, barriers, and lessons learned.

OBJECTIVES: We examined primary care and public health activities among federally funded health centers, to better understand their successes, the barriers encountered, and the lessons learned. METHODS: We used qualitative and quantitative methods to collect data from 9 health centers, stratified by administrative division, urban-rural location, and race/ethnicity of patients served. Descriptive data on patient and institutional characteristics came from the Uniform Data System, which collects data from all health centers annually. We administered questionnaires and conducted phone interviews with key informants. RESULTS: Health centers performed well on primary care coordination and community orientation scales and reported conducting many essential public health activities. We identified specific needs for integrating primary care and public health: (1) more funding for collaborations and for addressing the social determinants of health, (2) strong leadership to champion collaborations, (3) trust building among partners, with shared missions and clear expectations of responsibilities, and (4) alignment and standardization of data collection, analysis, and exchange. CONCLUSIONS: Lessons learned from health centers should inform strategies to better integrate public health with primary care.

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.

Effects of length of stay and language proficiency on health care experiences among immigrants in Canada and the United States.

This study sought to examine the influence of length of stay and language proficiency on immigrants' access to and utilization of care in Canada and the United States (U.S,). Data came from the 2007-2008 Canadian Community Health Survey and the National Health Interview Survey. Analyses were limited to foreign-born, non-elderly adults in each country (n = 12,870 in Canada and n = 7440 in the U.S.). Health care indicators included having a usual source of care; annual consultation with a health professional, dentist, and eye doctor; flu shot in the past year; and Pap test in the past 3 years. Logistic regression models were employed to estimate the relative odds of access or use of care, adjusting for need, demographic factors, socioeconomic status, and insurance coverage. In general, rates of health care access and utilization were higher in Canada than the U.S. among all immigrant groups. In both countries, adjusted analyses indicated that immigrants with shorter length of stay (less than 10 years) and limited language proficiency generally had lower rates of access/use compared with those with longer length of stay (10 years or more) and proficiency in each country's official language(s), respectively. There was one exception to this pattern in the U.S.: immigrants with limited English had higher odds of having a recent Pap test relative to English-proficient immigrants. The persistence of disparities in health care experiences based on length of stay and language proficiency in Canada suggests that universal health insurance coverage may not be sufficient for ensuring access to and utilization of primary and preventive care for this population.

Health, behavior, and health care disparities: disentangling the effects of income and race in the United States.

The literature on health disparities in the United States typically focuses on race/ethnicity or on socioeconomic status (SES) separately, but not often together. The purpose of the study was to assess the separate effects of race/ethnicity and SES on health status, health behaviors, and health care utilization. Cross-sectional analyses were conducted using the 2008 National Health Interview Survey (n = 17,337 non-elderly adults). SES disparities within specific racial groups were examined, as were race disparities within high and low SES groups. Within each racial/ethnic group, a greater proportion of low versus high SES individuals were in poor health, a lower proportion had healthy behaviors, and a lower proportion had access to care. In both SES groups, blacks and Hispanics had poorer health outcomes than whites. While whites were more likely to exercise than blacks and Hispanics, they are more likely to be smokers and less likely to have no or moderate alcohol consumption. Blacks had similar or better health care use than whites, especially for cancer screening; Hispanics had lower use within each SES group. Race/ethnicity disparities among adults of similar incomes, while important, were dwarfed by the disparities identified between high- and low-income populations within each racial/ethnic group.

US primary care delivery after the Health Center Growth Initiative: comparison of health centers, hospital outpatient departments, and physicians' offices.

We compared patient management during primary care visits in 3 settings (health centers, hospital outpatient departments, and physicians' offices) and investigated racial/ethnic and insurance-based disparities in the wake of the recent health center program expansion. Within health centers, there were few differences in patient management across racial/ethnic or insurance groups. In contrast, the other settings displayed more racial/ethnic and insurance disparities in patient management during visits. Health centers performed processes of care with comparable or higher occurrence, relative to physicians' offices. Health care disparities were also attenuated in health centers, compared with other primary care settings.

Cancer screening among racial/ethnic and insurance groups in the United States: a comparison of disparities in 2000 and 2008.

Using the National Health Interview Survey, we examined associations among race/ ethnicity, insurance coverage, and cancer screening, and assessed changes in the magnitude of disparities over the past decade. Outcomes included recent cervical, breast, and colorectal cancer screening. Rates of colorectal screening increased for all racial/ethnic groups and some insurance groups from 2000 to 2008. However, rates of Pap tests and mammograms remained stagnant, and even decreased for certain groups. Some Hispanic-White and Asian-White disparities in cancer screening were reduced or eliminated over this time period. However, in 2008 Asians continued to have lower odds of Pap tests and Hispanics lower odds of colorectal cancer screening, even after accounting for potential confounders. There were no significant changes in Black-White disparities. The uninsured continued to be at a disadvantage for all three types of cancer screening, relative to the privately insured, as were publicly insured individuals with respect to colorectal cancer screening.

Nativity status and access to care in Canada and the U.S.: factoring in the roles of race/ethnicity and socioeconomic status.

We conducted cross-country comparisons of Canada and the U.S., and assessed the extent to which access to care varies by nativity status overall, as well as in conjunction with race/ethnicity and socioeconomic status. Data came from the Joint Canada-U.S. Survey of Health (n=6,620 non-elderly adults). Access measures included having a regular medical doctor, consultation with a health professional in the past year, dentist visit in the past year, Pap test in the past three years, and any unmet health care needs in the past year. Logistic regression was employed to estimate the relative odds of access to care, adjusting for potential confounders. Disparities in access to care based on nativity status overall, as well as nativity-by-race joint effects, were found in both countries. There was also a dose-response effect of education on access to care among the native-born but not among the foreign-born; there were few nativity-by-income joint effects.

Characteristics of ambulatory care patients and services: a comparison of community health centers and physicians' offices.

The overall aim was to determine whether health care delivery for vulnerable populations served by community health centers (CHCs) was comparable to care for mainstream Americans primarily seen in physicians' offices (POs). Data came from the 2006 National Ambulatory Medical Care Survey. Patient visits occurring in CHCs were largely from younger, uninsured or Medicaid-insured, minority populations, while POs catered mainly to older, Medicare- or privately-insured, White patients. Communities served by CHCs were more often in low-income, low-education, urban regions. A greater proportion of visits to CHCs were from diabetic, obese, and depressed patients; CHCs also offered more evening/weekend visits and provided more health education during visits, but spent less time per visit than POs and had more difficulty referring patients to specialists. Results affirmed the significant role of CHCs as safety-net providers for vulnerable populations, and indicated that CHCs provide adequate care compared with POs although there remains room for improvement.

Access to primary and preventive care among foreign-born adults in Canada and the United States.

OBJECTIVE: To conduct cross-country comparisons and assess the effect of foreign birth on access to primary and preventive care in Canada and the United States. DATA SOURCES: Secondary data from the 2002 to 2003 Joint Canada-United States Survey of Health. STUDY DESIGN: Descriptive and comparative analyses were conducted, and logistic regression models were used to assess the effect of immigrant status and country of residence on access to care. Outcomes included measures of health care systems and processes, utilization, and patient perceptions. PRINCIPAL FINDINGS: In adjusted analyses, immigrants in Canada fared worse than nonimmigrants regarding having timely Pap tests; in the United States, immigrants fared worse for having a regular doctor and an annual consultation with a health professional. Immigrants in Canada had better access to care than immigrants in the United States; most of these differences were explained by differences in socioeconomic status and insurance coverage across the two countries. However, U.S. immigrants were more likely to have timely Pap tests than Canadian immigrants, even after adjusting for potential confounders. CONCLUSIONS: In both countries, foreign-born populations had worse access to care than their native-born counterparts for some indicators but not others. However, few differences in access to care were found when direct cross-country comparisons were made between immigrants in Canada versus the United States, after accounting for sociodemographic differences.

Access to medical care, dental care, and prescription drugs: the roles of race/ethnicity, health insurance, and income.

BACKGROUND: After accounting for socioeconomic factors and other demographic characteristics, racial/ethnic disparities in access to care were examined. METHODS: Using nationally representative data on 34,403 individuals from the 2004 Medical Expenditure Panel Survey (MEPS), multiple logistic regression analyses for five outcome measures were conducted: self-reports of being unable to get medical care, dental care, or prescriptions in the past year; and having no doctor or dentist visits in the past year. The main independent variables were race/ethnicity, income, and insurance status. RESULTS: Blacks and Hispanics were less likely to report difficulties in accessing medical care, dental care, and prescriptions as compared to whites. These disparities occurred primarily among the uninsured and Medicaid insured. More objective measures of utilization (ie, no doctor visit or dental visit during the past year) showed that minorities experienced less access than whites. CONCLUSIONS: Racial/ethnic disparities in access to care persist, and cannot be entirely explained by socioeconomic differences. In addition, the nature of these disparities depends on the socioeconomic position of racial/ethnic groups as well as the access measure used.

Usual source of care and the quality of medical care experiences: a cross-sectional survey of patients from a Taiwanese community.

OBJECTIVE: This study used a recent patient survey to examine the relationship between having a usual source of care (USC) and the quality of ambulatory medical care experiences in Taiwan, where there is universal health insurance coverage. RESEARCH DESIGN, SUBJECTS, AND MEASURES: The study design was a cross-sectional survey of 879 patients in Taichung County, Taiwan. Children and adults visiting hospital-based physicians were included. Quality of care was measured using items from the Primary Care Assessment Tool (PCAT), representing 7 ambulatory medical care domains: first contact (ie, access and utilization), longitudinality (ie, ongoing care), coordination (ie, referrals and information systems), comprehensiveness (ie, services available and provided), family centeredness, community orientation, and cultural competence. USC was defined based on responses to 3 survey items from the PCAT. RESULTS: Having a USC was significantly associated with higher quality of medical care experiences. Specifically, having a USC was associated with improved accessibility and utilization, ongoing care, coordination of referrals, and healthcare providers' family centeredness and cultural competence. However, having a USC was not strongly related with comprehensiveness of services, coordination of information systems, or healthcare providers' community orientation. CONCLUSION: In a region with universal health insurance, patients with a USC reported higher quality of medical care experiences compared with those without a USC. Beyond the provision of health insurance coverage, efforts to improve quality of care should include policies promoting USC.

Physician specialty and the quality of medical care experiences in the context of the Taiwan national health insurance system.

OBJECTIVES: Based on a recent patient survey from Taiwan, where there is universal health insurance coverage and unrestricted physician choice, this study examined the relationship between physician specialty and the quality of primary medical care experiences. METHODS: We assessed ambulatory patients' experiences with medical care using the Primary Care Assessment Tool, representing 7 primary care domains: first contact (ie, accessibility and utilization); longitudinality (ie, ongoing care); coordination (ie, referrals and information systems); comprehensiveness (ie, services available and provided); family centeredness; community orientation; and cultural competence. RESULTS: Having a primary care physician was significantly associated with patients reporting higher quality of primary care experiences. Specifically, relative to specialty care physicians, primary care physicians enhanced accessibility, achieved better community orientation and cultural competence, and provided more comprehensive services. CONCLUSIONS: In an area with universal health insurance and unrestricted physician choice, ambulatory patients of primary care physicians rated their medical care experiences as superior to those of patients of specialists. In addition to providing health insurance coverage, promoting primary care should be included as a health policy to improve patients' quality of ambulatory medical care experiences.

Assessing the impact of the Health Center Growth Initiative on health center patients.

OBJECTIVES: In 2001, the Health Center Growth Initiative was launched to increase access to primary health-care services through the expansion of the health center program. We examined the impact this initiative had on the number and types of patients seen by health centers, as well as the health center characteristics significantly associated with service expansions. METHODS: We conducted secondary and time-trend analyses of the Uniform Data System, an annual dataset submitted to the Bureau of Primary Health Care by all federally qualified health centers. We performed trend and multivariable analyses to examine the impact of the initiative on health center performance. RESULTS: Health centers that received both new access points and expanded medical capacity funding saw the most rapid growth in patients. These centers experienced a 58% increase in total number of patients and a 60% increase in total number of encounters, compared with 10% and 8%, respectively, for centers receiving no funding at all. CONCLUSIONS: were unchanged even after controlling for other health center characteristics. CONCLUSIONS: Public funding is critical to sustaining and expanding health center services to the nation's vulnerable populations.

The influence of English proficiency on access to care.

OBJECTIVE: The number of individuals with limited English proficiency in the USA is large and rapidly growing. Consequently, addressing language barriers in access to medical care is becoming increasingly important. Previous studies have reported that individuals with limited English proficiency have more difficulty gaining access to care, compared to English-proficient individuals. We assessed the impact of English language proficiency on access to medical care, accounting for health and socioeconomic status, using nationally representative data. DESIGN: Cross-sectional data from the 2006 National Health Interview Survey (n=29,868). The main outcome measures of interest were self-reported delayed medical care, forgone needed care, and visits to a health care professional. RESULTS: In unadjusted analyses, individuals with limited English proficiency were more likely to forgo needed medical care and less likely to have a health care visit, compared to individuals who were proficient in English. There was no significant association between language proficiency and reports of delayed care. After accounting for individuals' health and socioeconomic status, only the relationship between limited English proficiency and health care visits remained statistically significant. Most associations between language proficiency and access to care did not differ across various racial/ethnic groups. CONCLUSION: Results indicate that the choice of access measure may influence conclusions about language barriers in health care. Given the growing proportion of US residents with limited English proficiency, health care settings need to better address potential language barriers.

Racial/ethnic and socioeconomic disparities in access to care and quality of care for US health center patients compared with non-health center patients.

This study aims to compare racial/ethnic and socioeconomic disparities in access to care and quality of care for US health center patients and non-health center patients. Data for the study came from the 2002 Community Health Center User Survey and the 2003 National Healthcare Disparities Report. Descriptive analysis was performed using nationally representative survey data pertaining to access to care and quality of care for people of different races, ethnicities, incomes, and education levels. Results of the study show that health center patients experience fewer racial/ethnic and socioeconomic disparities in access to care and quality of care, compared with non-health center patients nationally. Racial/ethnic disparities favoring whites occur in non-health center patients in every measure of quality and access included in this study. Conversely, there are few disparities favoring whites among health center users. Education and income-related disparities occur for several measures of access and quality in both health center and non-health center patients; however, the magnitude of these disparities is usually greater among non-health center patients compared with health center patients. In conclusion, health centers have been touted for cost-efficient, high-quality care. This study adds to growing evidence that health centers may also help eliminate racial/ethnic and socioeconomic disparities in access to care and quality of care.
