OBJECTIVE Consumer assessments of health care provide important information about how well health plans and clinicians meet the needs of the people they serve. The purpose of this study was to examine whether consumer reports and ratings of care in Medicaid managed care vary by race/ethnicity and language. DATA SOURCES Data were derived from the National CAHPS Benchmarking Database (NCBD) 3.0 and consisted of 49,327 adults enrolled in Medicaid managed care plans in 14 states in 2000. DATA COLLECTION The CAHPS data were collected by telephone and mail. Surveys were administered in Spanish and English. The response rate across plans was 38 percent. STUDY DESIGN Data were analyzed using linear regression models. The dependent variables were CAHPS 2.0 global rating items (personal doctor, specialist, health care, health plan) and multi-item reports of care (getting needed care, timeliness of care, provider communication, staff helpfulness, plan service). The independent variables were race/ethnicity, language spoken at home (English, Spanish, Other), and survey language (English or Spanish). Survey respondents were assigned to one of nine racial/ethnic categories based on Hispanic ethnicity and race: White, Hispanic/Latino, Black/African American, Asian/Pacific Islanders, American Indian/Alaskan native, American Indian/White, Black/White, Other Multiracial, Other Race/Ethnicity. Whites, Asians, and Hispanics were further classified into language subgroups based on the survey language and based on the language primarily spoken at home. Covariates included gender, age, education, and self-rated health. PRINCIPAL FINDINGS Racial/ethnic and linguistic minorities tended to report worse care than did whites. Linguistic minorities reported worse care than did racial and ethnic minorities. CONCLUSIONS This study suggests that racial and ethnic minorities and persons with limited English proficiency face barriers to care, despite Medicaid-enabled financial access. Health care organizations should address the observed disparities in access to care for racial/ethnic and linguistic minorities as part of their quality improvement efforts.

This study was carried out to determine whether levels of physical activity of patients with various chronic diseases are associated with subsequent functioning and well-being. It was an observational 2-year longitudinal design. The setting was offices of medical and mental health practices within health maintenance organizations, large multispecialty groups, and solo practices or small single-specialty group practices in three U.S. cities. Included in the study were 1758 adult patients with one or more of the following: diabetes, hypertension, congestive heart failure, recent myocardial infarction, depressive symptoms, or current depressive disorder. Outcome measures included physical, role, and functioning; energy/fatigue; pain intensity; sleep problems; depressed affect, anxiety, positive affect, and overall psychological distress/well-being; health distress; and current health perceptions. Cross-sectional (base-line), 2-year endpoint, and change score relationships were evaluated between baseline levels of physical activity and each outcome, controlling for chronic conditions, comorbidity, smoking, alcohol use, overweight, self-reported adherence, and other patient and study characteristics. Higher baseline levels of exercise were uniquely associated with better functioning and well-being at baseline and 2 years later for some measures. The magnitude of the differences varied by disease group, but tended to be between 0.17 and 0.39 of the baseline SD. Greater levels of exercise are associated with feeling and functioning better for patients with chronic conditions over a 2-year period, suggesting that this is a fruitful area for further study using controlled interventions.

OBJECTIVES The Patient-Reported Outcomes Measurement Information System (PROMIS) allows assessment of the impact of chronic conditions on health-related quality of life (HRQL) across diseases. We report on the HRQL impact of individual and comorbid conditions as well as conditions that are described as limiting activity. STUDY DESIGN AND SETTING Data were collected through online and clinic recruitment as part of the PROMIS item calibration sample (n=21,133). Participants reported the presence or absence of 24 chronic health conditions and whether their activity was limited by each condition. RESULTS Across health status domains, the presence of a chronic condition was associated with poorer scores than those without a diagnosis, particularly for those individuals who reported that their condition was disabling. The magnitude of detriment in HRQL was more pronounced for individuals with two or more chronic conditions and could not be explained by sociodemographic factors. Patterns of HRQL deficits varied across disease and comorbidity status. CONCLUSION The impact of chronic conditions, particularly when experienced with comorbid disease, is associated with detriments in HRQL. The negative impact on HRQL varies across symptoms and functional areas within a given condition.

Agreement between self reports and proxy reports of quality of life was examined in a sample of 292 patients with epilepsy and their designated proxies. Patients and proxies completed an 89-item Quality of Life Inventory (QOLIE-89), with the items rephrased for the proxy. Results reveal moderate correlations (product-momentr ranging from 0.29 to 0.56 for 17 multi-item scales) between self reports and proxy reports. Agreement was good for measures of function that are directly observable and relatively poor for more subjective measures. Mean scale scores were significantly different between patients and proxies for only five of 17 multi-item scales. Proxy respondents systematically reported better functioning than did patients in three scales assessing cognitive functioning (allp<0.001). By contrast, patients reported more positive health perceptions and less seizure distress than proxies. Patient educational attainment correlated inversely with degree of disagreement between patient and proxy reports for six of the 17 QOL scales and for the overall score. In addition, proxy educational attainment correlated positively with agreement for four scales. This study indicates that for group level comparisons, proxy respondents can be substituted for adults with epilepsy having low to moderate seizure frequency. However, for individual level assessments proxies should be used with caution.

There is a need for a psychometrically sound measure of the stigma experienced by diverse persons living with HIV/AIDS (PLHA). The goal of this study was to develop and evaluate a multidimentional measure of internalized HIV stigma that captures stigma related to treatment and other aspects of the disease among sociodemographically diverse PLHA. We developed a 28-item measure of internalized HIV stigma composed of four scales based on previous qualitative work. Internal consistency reliability estimates in a sample of 202 PLHA was 0.93 for the overall measure, and exceeded 0.85 for three of the four stigma scales. Items discriminated well across scales, and correlations of the scales with shame, social support, and mental health supported construct validity. This measure should prove useful to investigators examining in the role of stigma in HIV treatment and health outcomes, and evaluating interventions designed to mitigate the impacts of stigma on PLHA.

Paul P. Lee; Karen Spritzer; Ron D. Hays

OBJECTIVE To determine the impact of blurred vision on functional status and well-being, the authors used a cross-sectional analysis of Medical Outcomes Study (MOS) 2-year follow-up data. METHODS One thousand six hundred forty-two respondents were asked to report how often they experienced blurred vision not correctable by glasses or contact lenses, as well as other various symptoms, at the 2-year follow-up. Participants completed the SF-36, a general functioning and well-being instrument. Demographic, medical, and other data also were collected. The association of these symptoms, including blurred vision, and tracer medical conditions with SF-36 scores were evaluated. RESULTS The unique impact of blurred vision on role limitations due to physical health problems was significantly greater than the impact of hypertension, history of myocardial infarction, type II diabetes mellitus, indigestion, trouble urinating, and headache. Blurred vision also had a significantly greater negative impact on energy than Type I diabetes mellitus, on social function than indigestion, and on physical functioning than trouble urinating. CONCLUSIONS Having blurred vision more than once or twice a month has a detectable and significant impact on functional status and well-being, especially in role limitations due to physical health problems. This demonstrates the impact of a common visual symptom on health status and well-being, as measured by the SF-36. In addition, comparison of the impact of various symptoms and conditions provides important and potentially clinically relevant information.

Assessing individual change is feasible and potentially useful in clinical practice. This article provides an overview of the evaluation of statistically significant change in health-related quality of life (HRQOL) for individual patients. We review the standard error of measurement, standard error of prediction, and reliable change indices using a sample of 54 patients receiving care at the UCLA Center for East-West Medicine. The largest amount of change necessary for statistical significance was found for the reliable change index and the smallest change was needed for the standard error of measurement. The amount of change required for statistical significance was intermediate for the standard error of prediction. The median kappa for classifying change (declined, stayed the same, improved) by different indices was .82, indicating a high level of agreement. Future research is needed to determine if one index is most appropriate for evaluating the significance of individual change.

Arlene Fink; Sally C. Morton; John C. Beck; Ron D. Hays; Karen Spritzer; Sabine M. Oishi; Alison A. Moore

OBJECTIVES: Older adults can incur problems at low levels of alcohol consumption because of age‐related physiological changes, declining health and functional status, and medication use. We have developed and tested a screening measure specifically for older people, the Alcohol‐Related Problems Survey (ARPS), to identify older adults with these risks.

Patient-centered measures of functioning and well-being are needed to monitor and improve health for HIV-infected persons. We estimated the associations between HRQOL and symptoms over time in HIV-infected persons, adjusting for demographic and clinical characteristics using a longitudinal study of a nationally representative cohort of 2267 patients in care for HIV infection surveyed in 1996 and again in 1998. We used two global measures of HRQOL (overall health and overall quality of life) scored to have a mean of 50 and standard deviation of 10 in the sample. The total number of symptoms decreased (−1.29, p<0.001 for the difference), and overall health (1.09, p<0.001 for the difference) and overall quality of life (1.31, p<0.001 for the difference) improved over the period. Controlling for baseline symptoms and HRQOL, each additional symptom at follow-up (B=−1.14, p<0.001) was associated with worsened overall health and worsened overall quality of life (B=−0.95, p<0.001). The association of two additional symptoms with lower global HRQOL was similar in magnitude to the effect of having significant depressive symptoms or the diagnosis of AIDS. In conclusion, among HIV-infected patients, symptoms are significantly related to HRQOL over time. The functioning and well-being of patients with HIV is inextricably linked to the symptoms they experience.

Health Plan Effects on Patient Assessments of Medicaid Managed Care Among Racial/Ethnic Minorities

Robert Weech-Maldonado; Marc N. Elliott; Leo S. Morales; Karen Spritzer; Grant N. Marshall; Ron D. Hays

AbstractOBJECTIVE: To examine the extent to which racial/ethnic differences in Consumer Assessment of Health Plans Study (CAHPS) ratings and reports of Medicaid managed care can be attributed to differential treatment by the same health plans (within-plan differences) as opposed to racial/ethnic minorities being disproportionately enrolled in plans with lower quality of care (between-plan differences). DESIGN: Data are from the National CAHPS Benchmarking Database (NCBD) 3.0. Data were analyzed using linear regression models to determine the overall effects, within-plan effects, and between-plan effects of race/ethnicity and language on patient assessments of care. Standard errors were adjusted for nonresponse weights and the clustered nature of the data. PATIENTS/PARTICIPANTS: A total of 49,327 adults enrolled in Medicaid managed care plans in 14 states from 1999 to 2000. MAIN RESULTS: Non-English speakers reported worse experiences compared to those of whites, while Asian non-English speakers had the lowest scores for most reports and ratings of care. An analysis of between-plan effects showed that African Americans, Hispanic-Spanish speakers, American Indian/Whites, and White-Other language were more likely than White-English speakers to be clustered in worse plans as rated by consumers. However, the majority of the observed racial/ethnic differences in CAHPS reports and ratings of care are attributable to within-plan effects. The ratio of between to within variance of racial/ethnic effects ranged from 0.07 (provider communication) to 0.42 (health plan rating). CONCLUSIONS: The observed racial/ethnic differences in CAHPS ratings and reports of care are more a result of different experiences with care for people enrolled in the same plans than a result of racial/ethnic minorities being enrolled in plans with worse experiences. Health care organizations should engage in quality improvement activities to address the observed racial/ethnic disparities in assessments of care.
