Disparities in health care by race, ethnicity, and language among the insured: findings from a national sample.

BACKGROUND: Racial and ethnic disparities in health care have been well documented, but poorly explained. OBJECTIVE: To examine the effect of access barriers, including English fluency, on racial and ethnic disparities in health care. RESEARCH DESIGN: Cross-sectional analysis of the Community Tracking Survey (1996-1997). SUBJECTS: Adults 18 to 64 years with private or Medicaid health insurance. MEASURES: Independent variables included race, ethnicity, and English fluency. Dependent variables included having had a physician or mental health visit, influenza vaccination, or mammogram during the past year. RESULTS: The health care use pattern for English-speaking Hispanic patients was not significantly different than for non-Hispanic white patients in the crude or multivariate models. In contrast, Spanish-speaking Hispanic patients were significantly less likely than non-Hispanic white patients to have had a physician visit (RR, 0.77; 95% CI, 0.72-0.83), mental health visit (RR, 0.50; 95% CI, 0.32-0.76), or influenza vaccination (RR, 0.30; 95% CI, 0.15-0.52). After adjustment for predisposing, need, and enabling factors, Spanish-speaking Hispanic patients showed significantly lower use than non-Hispanic white patients across all four measures. Black patients had a significantly lower crude relative risk of having received an influenza vaccination (RR, 0.73; 95% CI, 0.58-0.87). Adjustment for additional factors had little impact on this effect, but resulted in black patients being significantly less likely than non-Hispanic white patients to have had a visit with a mental health professional (RR, 0.46; 95% CI, 0.37-0.55). CONCLUSIONS: Among insured nonelderly adults, there are appreciable disparities in health-care use by race and Hispanic ethnicity. Ethnic disparities in care are largely explained by differences in English fluency, but racial disparities in care are not explained by commonly used access factors.

Effect of patient socioeconomic status on physician profiles for prevention, disease management, and diagnostic testing costs.

BACKGROUND: Previous research shows patient socioeconomic status (SES) affects physician profiles for health status and satisfaction, but effects on other aspects of care are not known. OBJECTIVE: To examine the effect of patient SES on physician profiles for preventive care, disease management, and diagnostic testing costs. RESEARCH DESIGN: Cross-sectional analysis of a managed care claims data. SUBJECTS: Five hundred sixty-eight physicians and 600,618 patients. MEASURES: Patient age, gender, case-mix, and SES based on zip code, likelihood of having a Papanicolaou smear, mammogram, for diabetics having had a glycosylated hemoglobin, diabetic eye exam, and diagnostic testing costs. RESULTS: For each performance indicator, except glycosylated hemoglobin, there was a statistically significant effect of adjusting for patient SES. For diabetic eye checks, mammograms and Papanicolaou tests respectively, 5%, 16%, and 21% of physicians who were outliers (in the top or bottom 5% of rankings) were no longer outliers after socioeconomic adjustment. For all performance measures the change in physician ranking was strongly correlated with the mean practice SES. CONCLUSIONS: Patient SES, as measured by zip code, appreciably affects physician profiles for preventive care and diabetes management. Monitoring patient SES using patient zip codes could be used to target resources to improve outcomes for higher risk patients.

Health care utilization and adults who are deaf: relationship with age at onset of deafness.

OBJECTIVES: To evaluate the health care utilization of a nationally representative sample of U.S. deaf adults while accounting for the age at onset of deafness, an indicator of linguistic and sociocultural group affiliation. DATA SOURCES/STUDY SETTING: Data from the 1990 to 1991 National Health Interview Surveys the most recent years the Hearing Supplement was administered. The data were collected during in-home interviews of a sample of the U.S. civilian noninstitutionalized population. STUDY DESIGN: Cross-sectional analyses comparing health-related measures of adults deafened before (prelingually) and after (postlingually) the age of 3 and those of a representative sample of the general population, adjusting for sociodemographics and health status. Key measures were physician visits and preventive health care services utilization. PRINCIPAL FINDINGS: Compared with the general population, prelingually deafened adults had fewer physician visits and were less likely to have visited a physician in the preceding 2 years, whereas postlingually deafened adults had more physician visits and were more likely to have visited a physician in the preceding 2 years. Postlingually deafened women were less likely to have had a mammogram within the previous 2 years. CONCLUSIONS: In terms of health care utilization, the deaf population is heterogeneous. Prelingually deafened adults' use of health care is similar to that of other language minority groups. Postlingually deafened adults' use of health care services appears similar to people with chronic illness. Future studies must distinguish different groups of people with hearing loss in order to identify barriers and monitor improvements in health care services access.

Physician gender, patient gender, and primary care.

BACKGROUND: Studies of the effects of physician gender on patient care have been limited by selected samples, examining a narrow spectrum of care, or not controlling for important confounders. We sought to examine the role of physician and patient gender across the spectrum of primary care in a nationally representative sample, large enough to examine the role of gender concordance and adjust for confounding variables. METHODS: We examined the relationships between physician and patient gender using nationally representative samples (the U. S. National Ambulatory Medical Care Surveys from 1985 to 1992) of encounters of 41,292 adult patients with 1470 primary care physicians (internists, family physicians, and obstetrician/gynecologists). Factors examined included physician (age, gender, region, rural location), patient (age, gender, race, insurance), and visit characteristics (diagnoses, gender-specific and nonspecific prevention, duration, continuity, and disposition). RESULTS: After multivariate adjustment, female physicians were more likely to see female patients, had longer visit durations, and were more likely to perform female prevention procedures and make some follow-up arrangements and referrals. Female physicians were slightly more likely to check patients blood pressure, but there were no significant differences in other nongender-specific prevention procedures or use of psychiatric diagnoses. Among encounters without breast or pelvic examinations, visit length was not related to physician gender, but length was longer in gender concordant visits than gender-discordant visits. CONCLUSIONS: Female physicians were more likely to deliver female prevention procedures, but few other physician gender differences in primary care were observed. Physician-patient gender concordance was a key determinant of encounters.

Mapping the SF-12 to the EuroQol EQ-5D Index in a national US sample.

BACKGROUND: Preference scores for the Medical Outcomes Study (MOS) SF-12 would enable its use in cost-effectiveness analyses. Previous mapping studies of MOS instruments top reference-based instruments have not examined performance in national samples. PARTICIPANTS: 15,000 adults in the 2000 Medical Expenditure Panel Survey annual survey including the SF-12 and EQ-5D Index. METHODS: Regression of the EQ-5D Index scores onto the physical and mental component summary scores of the SF-12, testing 2nd-4th degree polynomial and spline models, including and excluding sociodemographics. RESULTS: A 2nd degree polynomial model explained 63% of the variance in EQ-5D scores, with robust internal and external validation. More complex mod-els explained minimally additional variance. Compared with EQ-5D valuations, prediction models overestimated the lowest health states (6% of the population). CONCLUSIONS: The mapped SF-12 yields usable preference-scaled scores, with some caution for the lowest health states.

Age-related disparities in cancer screening: analysis of 2001 Behavioral Risk Factor Surveillance System data.

PURPOSE: Although few studies have explored age-related health care disparities, some researchers have asserted such disparities uniformly disfavor the elderly and are largely attributable to ageism in the health care system. We compared age-related patterns of screening for colorectal cancer with those for breast and prostate cancer in persons aged 50 years and older. METHODS: We analyzed data for all adults aged 50 years and older (N = 88,213) in the 2001 Behavioral Risk Factor Surveillance System (BRFSS), a nationally representative, telephone-administered survey of personal health behaviors. Main outcome measures were adjusted prevalence by 5-year age-groups of colorectal cancer screening using fecal occult blood testing, flexible sigmoidoscopy, or colonoscopy for men and women; rates of mammography screening for women; and rates of prostate-specific antigen (PSA) screening for men. RESULTS: After adjustment for race/ethnicity, education level, income, health insurance, and self-rated health, predicted reported colorectal cancer screening (all modalities) increased significantly from when patients reached age 50 years until 70 to 74 years (66.0%, standard error [SE] 0.8%), remained constant until age 80 years, and then declined. The age-related gain in colorectal cancer screening was confined to whites among patients older than 60 years. Reported PSA screening increased until age 75 to 79 years (79.3%, SE 1.1%) and then declined, whereas reported mammography screening peaked at age 55 to 59 years (83.3%, SE 1.2%) and then declined. CONCLUSIONS: Significant age-related disparities appear to exist for both evidence-based and non-evidence-based cancer-screening interventions. The issue of age-related disparities in cancer screening is complex, with the direction of disparity favoring the elderly for some services yet disfavoring them for others.

Do HMOs affect educational disparities in health care?

BACKGROUND: We wanted to examine how membership in a health maintenance organization (HMO) is related to delivery of preventive clinical services to patients with different educational levels. METHODS: We conducted a cross-sectional analysis of the 1996-1997 Community Tracking Study Household Survey among adults aged 18 to 64 years with private or Medicaid health insurance. We examined interactions between respondent educational level and HMO membership for the following measures: having a regular source of care and, in the past year, having had a physician visit, a mental health visit, a mammogram (women > or = 50 years), an influenza vaccination (ages > or = 55 years), or smoking cessation counseling (smokers). RESULTS: After adjustment for sociodemographic factors, community size, insurance type, physical and mental health status, and smoking, respondents with less education were significantly less likely to have had a physician visit or mental health visit, mammogram, or influenza vaccination in the past year. Disparities in receipt of preventive care by educational level were smaller among HMO members. Differences in disparities between HMO members and non-HMO members reached statistical significance for influenza vaccination and showed a trend for mental health visits (P = .06). Moreover, HMO members with less than 12 years of education received services at levels comparable to non-HMO members with more education. CONCLUSIONS: There are appreciable disparities in receipt of preventive care by education among nonelderly insured persons. HMO membership is associated with smaller disparities for some services. Those with the lowest levels of education appeared to benefit the most from HMO membership.

On being new to an insurance plan: health care use associated with the first years in a health insurance plan.

BACKGROUND: We wanted to compare health care utilization and costs in the first year of being in a health insurance plan with those of subsequent years. METHODS: We used claims data from an independent practitioner association (IPA)-style managed care organization in the Rochester, NY, metropolitan area from 1996 through 1999. Cross-sectional and panel analyses of up to 4 years of claims data were conducted, involving 335,547 adult patients assigned to the panels of 687 primary care physicians (internists and family physicians). Multivariate analyses, adjusting for age, sex, case mix, and socioeconomic status derived from ZIP codes, examined the relationship between the first year of health insurance and Papanicolaou tests, mammograms in women older than 40 years, physician use, avoidable hospitalization, and expenditures. RESULTS: After multivariate adjustment, the first year of insurance was associated with a higher risk of not getting a mammogram, a higher risk of avoidable hospitalization, greater likelihood of visiting a physician, and higher expenditures, especially for testing. There was no relationship, however, between Papanicolaou test compliance and year of enrollment. CONCLUSIONS: The findings suggest there might be adverse clinical and financial implications associated with changing insurance.

Are patients' ratings of their physicians related to health outcomes?

PURPOSE: Observational studies using patient reports suggest associations between physician interpersonal styles and patient outcomes. Possible confounding of these associations has not been carefully examined. METHODS: Approximately 4,700 patients of 96 physicians completed a survey instrument that included reported health status changes during the previous year, perceptions of their physician (satisfaction, trust, knowledge of patient, and autonomy support), and sociodemographic and clinical covariates. We examined the adjusted relationship between patient perceptions of their physicians and reported health status changes. Using multilevel analyses, we then explored differences among physicians in patient perceptions of their physicians and whether these differences were explained by the relationship between patient perceptions and reported health status changes. RESULTS: There were significant adjusted relationships between patient perceptions of their physician and reported health status changes: better perceptions were associated with a smaller risk of health status decline (adjusted odds ratio = 1.14; 95% confidence interval [CI], 1.05-1.24; P <.01). Multilevel analysis showed significant differences between physicians in patient perceptions of their physicians (rho = 0.10; 95% CI, 0.07-0.13; P <.01), but these physician differences were unrelated to reported health status decline (rho = 0; P >.99). CONCLUSIONS: Using methods similar to those of previous studies, we found a relationship between patient perceptions of their physicians and reported health status declines. Multilevel analysis, however, suggested that this relationship is not a physician effect; it may reflect unmeasured patient confounding. Multilevel analyses may help to examine the relationships between physician styles and outcomes.

Rochester Participatory Decision-Making Scale (RPAD): reliability and validity.

PURPOSE: We wanted develop a reliable and valid objective measure of patient-physician collaborative decision making, the Rochester Participatory Decision-Making Scale (RPAD). METHODS: Based on an informed decision-making model, the RPAD assesses physician behavior that encourages patient participation in decision making. Data were from a study of physician-patient communication of 100 primary care physicians. Physician encounters with 2 standardized patients each were audio recorded, resulting in 193 useable recordings. Transcribed recordings were coded both with RPAD and the Measure of Patient-Centered Communication (MPCC), which includes a related construct, Finding Common Ground. Two sets of dependent variables were derived from (1) surveys of the standardized patients and (2) surveys of 50 patients of each physician, who assessed their perceptions of the physician-patient relationship. RESULTS: The RPAD was coded reliably (intraclass correlation coefficient [ICC] = 0.72). RPAD correlated with Finding Common Ground (r = 0.19, P < .01) and with the survey measures of standardized patient's perceptions of the physician-patient relationship (r = 0.32 - 0.36 [P < .005]) but less with the patient survey measures (r = 0.06 to 0.07 [P < .005]). Multivariate, hierarchical analyses suggested that the RPAD made a more robust contribution to explaining variance in standardized patient perceptions than did the MPCC Finding Common Ground. CONCLUSIONS: The RPAD shows promise as a reliable, valid, and easy-to-code objective measure of participatory decision making.

Patient-centered communication and diagnostic testing.

PURPOSE: Although patient-centered communication is associated with improved health and patient trust, information about the impact of patient-centered communication on health care costs is limited. We studied the relationship between patient-centered communication and diagnostic testing expenditures. METHODS: We undertook an observational cross-sectional study using covert standardized patient visits to study physician interaction style and its relationship to diagnostic testing costs. Participants were 100 primary care physicians in the Rochester, NY, area participating in a large managed care organization (MCO). Audio recordings of 2 standardized patient encounters for each physician were rated using the Measure of Patient-Centered Communication (MPCC). Standardized diagnostic testing and other expenditures, adjusted for patient demographics and case-mix, were derived from the MCO claims database. Analyses were adjusted for demographics and standardized patient detection. RESULTS: Compared with other physicians, those who had MPCC scores in the lowest tercile had greater standardized diagnostic testing expenditures (11.0% higher, 95% confidence interval [CI], 4.5%-17.8%) and greater total standardized expenditures (3.5% higher, 95% CI, 1.0%-6.1%). Whereas lower MPCC scores were associated with shorter visits, adjustment for visit length and standardized patient detection did not affect the relationship with expenditures. Total (testing, ambulatory and hospital care) expenditures were also greater for physicians who had lower MPCC scores, an effect primarily associated with the effect on testing expenditures. CONCLUSIONS: Patient-centered communication is associated with fewer diagnostic testing expenditures but also with increased visit length. Because costs and visit length may affect physicians' and health systems' willingness to endorse and practice a patient-centered approach, these results should be confirmed in future randomized trials.

Should years of schooling be used to guide treatment of coronary risk factors?

PURPOSE: We wanted to compare the risk of death from coronary heart disease (CHD) for patients of low socioeconomic status, measured by educational level, with established risk factors. METHODS: We undertook a prospective cohort study. Participants included a representative sample of 6,479 adults aged 25 to 74 years in the United States who were free of CHD at enrollment in the first National Health and Nutrition Examination Survey (NHANES I). RESULTS: Baseline measures included years of education, age, sex, systolic blood pressure, diabetes, total cholesterol level, and smoking. Outcome was death within 10 years from CHD. The relative risk (RR) associated with less than 12 years of education compared with more than 12 years (RR 1.5; 95% confidence interval [CI], 1.2-1.8) was comparable to being male (RR 1.4; 95% CI, 1.2-1.6), smoking (RR 1.4; 95% CI, 1.1-1.6), having a total cholesterol level of greater than 280 mg/dL (RR 1.6; 95% CI, 0.9-2.7), and systolic blood pressure of 130-139 mm Hg (RR 1.6; 95% CI, 1.0-2.4). Findings were comparable for estimates of absolute risk. CONCLUSIONS: Low educational level is associated with comparable risk as established risk factors for CHD mortality. Incorporation of educational level into risk-based guidelines for treatment could potentially reduce socioeconomic disparities in CHD by lowering thresholds for treatment.

Influence of accompanied encounters on patient-centeredness with older patients.

OBJECTIVES: To conduct a pilot study to examine physician patient interaction when elderly patients are accompanied during a medical visit. METHODS: This was a study in which 30 patients were randomly assigned to be accompanied (13) or unaccompanied (17) during a regular medical visit to their physician. Visits were tape recorded, transcribed, and coded with the Measure of Patient-Centered Communication (MPCC) and with the Rochester Participatory Decision-Making Scale (RPAD). RESULTS: We found no differences between the number of words spoken in accompanied versus unaccompanied visits, comparing patients alone with patients and companions combined. Physicians spoke longer without interruption in accompanied encounters (39.9 vs 78.6 words per speech turn). There were no differences in the level of MPCC or in the level of participatory decision making between the 2 types of visits. In accompanied visits, patients introduced most of the concerns and physicians discussed concerns with patients more than with companions. CONCLUSIONS: Previously reported differences in accompanied versus unaccompanied visits may reflect patients' preferences for being accompanied, the role they wish their companion to play, and the patients' health status. Being accompanied by a family member or friend does not result in less attention being paid to patients' concerns.

The National Lymphoedema Framework Project.

The National Lymphoedema Framework Project originated from an epidemiology study (Moffatt et al, 2003) carried out in South West London, which identified that lymphoedema is a significant but unrecognised problem. Lymphoedema is a chronic swelling arising from the accumulation of protein-rich fluid that would otherwise drain via the lymphatic system. It can be grossly disfiguring, and is associated with cancer and its treatment, particularly breast cancer, but it can occur for other reasons, such as trauma or parasitic infection, or it may be primary in origin (Fig 1). The main aim of the project is to provide sufficient evidence to persuade policy-makers that lymphoedema is a major problem that is currently under-resourced and for which national guidance for management is required.
