How many patients are needed to provide reliable evaluations of individual clinicians?

PURPOSE: The purpose of this study was to determine how many patients are needed to provide reliable patient ratings of care at the individual clinician level. SETTING AND SOURCES OF DATA: The study was conducted in an academic medical center and was based on analysis of 34,985 patients who completed a 50-item survey rating the care received during a recent outpatient visit to a physician or midlevel provider. STUDY DESIGN: Analyses of patient satisfaction surveys was done to: 1) confirm the dimensions of satisfaction with outpatient care in an existing measure, and 2) determine the number of patients required to provide reliable estimates of clinician care for single items and an 11-item composite scale. PRINCIPAL FINDINGS: Factor analysis showed that the survey measured 2 dimensions of satisfaction: 1) clinician care, and 2) features of visiting the office. The 11-item clinician care scale had high reliability (Cronbach's alpha=0.97). The number of patients needed to achieve reliability of 0.80 at the clinician level was 66 for the 11-item scale and ranged from 52 to 91 for individual items. For primary care physicians only, the comparable number of patients per clinician was 77 for the 11-item scale and ranged from 50 to 147 across items. CONCLUSIONS: For the survey items that we analyzed, the answer to the question "How many patients are needed to obtain useful and reliable feedback?" is at least 50, but varies by item type (global vs. specific) and by number of items (composite scale or single-item rating) and by the conditions of use (for self-assessment and learning or reward and punishment).

Racial differences in health-related quality of life among hemodialysis patients.

UNLABELLED: BACKGROUND; Despite technical progress in therapy, hemodialysis patients continue to report health-related quality of life (HRQOL) substantially lower than that of the general population. While African Americans with end-stage renal disease (ESRD) survive longer than members of other races, few studies have compared the HRQOL of African Americans with that of non-African Americans. METHODS: We examined differences in sociodemographic, clinical, and HRQOL variables by race. A multiple regression model assessed the extent to which race was associated with differences in HRQOL scores after adjustment for sociodemographic and clinical variables. Racial differences in the relationship between comorbid disease severity and HRQOL were explored. RESULTS; In adjusted models, African Americans had higher scores in the Index of Well-Being and burden of kidney disease, but lower scores in cognitive function (all P < 0.05). For scales reflecting symptoms and effects of kidney disease, sleep quality, and the Physical Component Summary, the fall in HRQOL with increasing comorbidity was significantly greater in non-African Americans (all P < 0.05). After adjustment, there were no racial differences in scores on the Mental Component Summary, social support, dialysis staff encouragement, or patient satisfaction. CONCLUSION: To our knowledge, ESRD is the only chronic illness for which African Americans report significantly better psychologic well being and a lower burden of disease than non-African Americans. Further research is needed to understand whether these experiences affect health care utilization, medical decision making, and patient survival. Clarification of the reasons for race differences may suggest measures to improve HRQOL for all patients with ESRD.

Health plan effects on patient assessments of Medicaid managed care among racial/ethnic minorities.

OBJECTIVE: 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.

Physician recognition of cognitive impairment: evaluating the need for improvement.

OBJECTIVES: To assess physician recognition of dementia and cognitive impairment, compare recognition with documentation, and identify physician and patient factors associated with recognition. DESIGN: Survey of physicians and review of medical records. SETTING: Health maintenance organization in southern California. PARTICIPANTS: Seven hundred twenty-nine physicians who provided care for women participating in a cohort study of memory (Women's Memory Study). MEASUREMENTS: Percentage of patients with dementia or cognitive impairment (using the Telephone Interview of Cognitive Status supplemented by the Telephone Dementia Questionnaire) recognized by physicians. Relationship between physician recognition and patient characteristics and physician demographics, practice characteristics, training, knowledge, and attitudes about dementia. RESULTS: Physicians (n=365) correctly identified 81% of patients with dementia and 44% of patients with cognitive impairment without definite dementia. Medical records documented cognitive impairment in 83% of patients with dementia and 26% of patients with cognitive impairment without definite dementia. In a multivariable model, physicians with geriatric credentials (defined as geriatric fellowship experience and/or the certificate of added qualifications) recognized cognitive impairment more often than did those without (risk ratio (RR)=1.56, 95% confidence interval (CI)=1.04-1.66). Physicians were more likely to recognize cognitive impairment in patients with a history of depression treatment (RR=1.3, 95% CI=1.03-1.45) or stroke (RR=1.37, 95% CI=1.04-1.45) and less likely to recognize impairment in patients with cognitive impairment without definite dementia than in those with dementia (RR=0.46, 95% CI=0.23-0.72) and in patients with a prior hospitalization for myocardial infarction (RR=0.37, 95% CI=0.09-0.88) or cancer (RR=0.49, 95% CI=0.18-0.90). CONCLUSION: Medical record documentation reflects physician recognition of dementia, yet physicians are aware of, but have not documented, many patients with milder cognitive impairment. Physicians are unaware of cognitive impairment in more than 40% of their cognitively impaired patients. Additional geriatrics training may promote recognition, but systems solutions are needed to improve recognition critical to provision of emerging therapies for early dementia.

Are physician-derived disease severity indices associated with health-related quality of life in patients with end-stage liver disease?

OBJECTIVES: Model for end-stage liver disease (MELD) score is now often used as an overall indicator of health status for patients with end-stage liver disease. However, there are no data evaluating the associations between MELD scores and patient reports of health-related quality of life (HRQOL). METHODS: Two hundred-three patients with end-stage liver disease completed a disease-targeted HRQOL instrument (the LDQOL 1.0). Patients also rated the severity of their liver disease and reported number of disability days attributed to their liver disease in the preceding month. MELD and Child Turcott Pugh (CTP) scores were calculated for all patients. Associations of MELD and CTP scores with patient-derived outcomes were estimated. RESULTS: The mean MELD and CTP scores were 12 and 7, respectively, indicating mild severity of liver disease. HRQOL of patients was generally poor, with the mean SF-36 physical and mental component summary scores of 35 and 40. Seventy percent of patients rated their liver disease symptoms as moderate to severe. Similarly, 70% reported being disabled from their liver disease. MELD was associated with physical functioning scale and the physical component summary (PCS) score in patients with end-stage liver disease. In contrast, CTP score was significantly associated with physical functioning, role limitations due to physical health problems, PCS score, effects of liver disease, sexual functioning, and sexual problems. Both MELD and CTP scores correlated with self-rated severity of liver disease symptoms but not with self-reported disability days. CONCLUSIONS: Despite objectively mild liver disease, the subjective HRQOL of this cohort was severely impaired. CTP score was more closely associated with patient-reported estimates of HRQOL than the MELD score. CTP or disease-specific HRQOL instruments may compliment MELD by providing insights into outcomes of importance to patients with low risk of mortality.

Delays and unmet need for health care among adult primary care patients in a restructured urban public health system.

OBJECTIVES: We estimated the prevalence and determinants of delayed and unmet needs for medical care among patients in a restructured public health system. METHODS: We conducted a stratified cross-sectional probability sample of primary care patients in the Los Angeles County Department of Health Services. Face-to-face interviews were conducted with 1819 adult patients in 6 languages. The response rate was 80%. The study sample was racially/ethnically diverse. RESULTS: Thirty-three percent reported delaying needed medical care during the preceding 12 months; 25% reported an unmet need for care because of competing priorities; and 46% had either delayed or gone without care. CONCLUSIONS: Barriers to needed health care continue to exist among patients receiving care through a large safety net system. Competing priorities for basic necessities and lack of insurance contribute importantly to unmet health care needs.

Commentary on using the SF-36 or MOS-HIV in studies of persons with HIV disease.

The purpose was to compare and comment on use of the SF-36 and MOS-HIV instruments in studies of persons with HIV disease. Three medical information databases were searched to identify examples of HIV studies that included the MOS-HIV or SF-36. Thirty-nine and 14 published articles were identified for illustration in comparing the use of the MOS-HIV and SF-36 in HIV disease, respectively. Support for the reliability and construct validity of the MOS-HIV and SF-36 was found. Ceiling and floor effects were reported for both the MOS-HIV and SF-36; however, ceiling effects were more common for the MOS-HIV, in part due to fewer items in the physical, social, and role functioning domains. The MOS-HIV measures three domains hypothesized to be associated with the health deterioration of HIV disease not measured by the SF-36; however, these domains may not assess aspects of HIV disease that typify the majority of the persons with HIV disease today. National norms for the U.S. adult population (and other nations) are available for the SF-36. In addition, the SF-36 has been used in a wide variety of patient populations, enabling comparisons of HIV-infected persons with persons with other health conditions. No national norms for the MOS-HIV are available. We conclude that there is currently insufficient evidence in the literature to recommend the use of the MOS-HIV over the SF-36 in HIV-infected persons. Although the SF-36 is not targeted at HIV, it may be preferable to use the SF-36 over the MOS-HIV due to fewer ceiling effects, availability of national norms, and the vast amount of data for other populations in the U.S. and around the world. Head-to-head comparisons demonstrating the unique value of the MOS-HIV over the SF-36 are clearly needed. More importantly, additional work needs to be directed at comparing the MOS-HIV and other putatively HIV-targeted instruments to one another to help demarcate aspects of HRQOL that are truly generic versus specific to HIV disease. Using both a generic and targeted HRQOL measure is a good general strategy, but this has not been a typical practice in studies of HIV because the MOS-HIV is so similar in content to the SF-36.

The diverse older HIV-positive population: a national profile of economic circumstances, social support, and quality of life.

The objectives of this study were to provide a national profile of socioeconomic circumstances of the middle-aged and older population living with HIV and to evaluate variations in social support and quality of life (QOL) across age and socioeconomic subgroups, controlling for indicators of disease progression. The design used was a cross-sectional analysis of nationally representative interview data on HIV-infected individuals collected in the HIV Cost and Services Utilization Study. Multiple measures of social support and QOL were used. Bivariate comparisons of outcomes across categories of age and exposure category were performed; multivariate analyses to isolate the effect of older age on outcomes within exposure categories were performed, controlling for socioeconomic and clinical co-variates. Study results indicate that older gay men with HIV/AIDS are a predominantly white population and more likely to have health insurance than their younger counterparts; 38% were employed and 48% reported incomes of more than $25,000. Older injection drug users (IDUs) with HIV/AIDS are a predominantly black population with a particularly high concentration of disadvantages; only 11% were employed and 74% reported incomes of less than $10,000. Older IDUs reported especially low levels of physical functioning and emotional support in comparison with their younger counterparts, whereas older gay men did not significantly differ from younger gay men in these respects. The authors conclude that characteristics and care needs of the older HIV-positive population are very diverse and vary sharply by exposure route. Interventions need to be tailored to the needs of these distinct subpopulations, with an emphasis on development of supportive care interventions for older IDUs.

Knowledge of antiretroviral regimen dosing and adherence: a longitudinal study.

In a cohort of 128 human immunodeficiency virus-infected patients, we found that patients' knowledge of antiretroviral dosing was suboptimal at regimen initiation but improved with time. Poor medication knowledge 8 weeks after regimen initiation was associated with lower adherence and with a lower level of literacy in a multivariate model (P=.03). Because knowledge deficits are common after antiretroviral regimen initiation, clinicians should assess patients' understanding of medication dosing soon after regimen initiation or change.

Associations of presbyopia with vision-targeted health-related quality of life.

OBJECTIVE: To evaluate the associations of presbyopia and its correction, particularly monovision optical correction, with vision-targeted health-related quality of life. METHODS: The National Eye Institute Refractive Error Quality of Life (NEI-RQL) Instrument was prospectively self-administered by subjects from 6 medical centers in the following age and correction categories: subjects with emmetropia younger than 45 years (n = 75), subjects with emmetropia aged 45 years or older (n = 38), and subjects with ametropia aged 45 years or older without monovision (n = 486) or corrected with monovision (n = 38). Differences in the 13 NEI-RQL Instrument subscale scores among subjects in the 4 groups were examined. The age of 45 years or older was used as a surrogate for presbyopia. RESULTS: A comparison of older (age > or =45 years) vs younger (age <45 years) persons with emmetropia suggests that presbyopia was associated with reduced scores in 7 of 13 subscales (P<.05). In those aged 45 years or older, correction of presbyopia with monovision was associated with statistically significantly better scores on 3 subscales (expectations, dependence on correction, and appearance) compared with single-vision correction. One subscale (dependence on correction) showed worsening scores with increasing age without adjustment for need or type of correction. Older persons with monovision correction had significantly worse scores than younger subjects with emmetropia on all subscales except suboptimal correction and appearance. CONCLUSIONS: Presbyopia is associated with worse vision-targeted health-related quality of life compared with younger subjects with emmetropia. Monovision correction of presbyopia is related to some improvements in health-related quality of life, but it is still worse than that for younger subjects with emmetropia in several areas.

Psychometric properties of the National Eye Institute-Refractive Error Quality of Life instrument.

OBJECTIVE: To estimate the psychometric properties of a vision-targeted measure of health-related quality of life, the National Eye Institute-Refractive Error Quality of Life survey (NEI-RQL), which includes 13 scales designed to assess the impact of refractive error and its correction on day-to-day life. DESIGN: Cross-sectional survey. PARTICIPANTS: The NEI-RQL was self-administered by 667 myopes, 380 hyperopes, and 114 emmetropes recruited from the practices of 6 medical centers. All participants had near and distance visual acuity of 20/32 or better in the worse eye while benefiting from their current method for correction of refractive error (glasses, contact lens, refractive surgery). METHODS: Mean scores, standard deviations, internal consistency reliability, and test-retest intraclass correlations were estimated for the NEI-RQL scales. Item discrimination was assessed by item-scale correlations. Construct validity was evaluated by assessing the sensitivity of scale scores to type of refractive error, type of refractive error correction, and spherical equivalent. Construct validity of the NEI-RQL was compared to those of the Medical Outcomes Study 36-item short-form health survey (SF-36) and the National Eye Institute Vision Functioning Questionnaire (NEI VFQ-25) in a random subsample of respondents. MAIN OUTCOME MEASURES: The 13 NEI-RQL scales-clarity of vision, expectations, near vision, far vision, diurnal fluctuations, activity limitations, glare, symptoms, dependence on correction, worry, suboptimal correction, appearance, and satisfaction with correction. RESULTS: Emmetropes tended to score significantly better on the NEI-RQL scales than myopes and hyperopes. The method of refractive error correction was also associated with NEI-RQL scores. In addition, the NEI-RQL multi-item scales accounted for 29% of the variance in the NEI-RQL satisfaction with correction item beyond that explained by the SF-36 and the NEI VFQ-25. CONCLUSION: These results support the reliability and construct validity of the NEI-RQL. The instrument appears to be useful for comparisons of people with different types of correction for refractive error.

Responsiveness of the National Eye Institute Refractive Error Quality of Life instrument to surgical correction of refractive error.

OBJECTIVE: Refractive error and the means by which it is corrected may impact substantially on quality of vision and health-related quality of life in ways not captured adequately by standard measures of visual acuity. The goal of this analysis was to evaluate the responsiveness of the National Eye Institute Refractive Error Quality of Life (NEI-RQL) instrument to surgical correction of refractive error. DESIGN: Prospective, multicenter cohort study. PARTICIPANTS: The NEI-RQL, a 42-item measure with 13 scales, was self-administered by 185 patients before and after undergoing surgical correction of myopic or hyperopic refractive error. Preoperative and postoperative clinical information was collected, including refractive error and corrected visual acuity. METHODS: Differences between preoperative and postoperative NEI-RQL scores were examined. Responsiveness was assessed using the standardized response mean and the responsiveness statistic. We also compared scales using relative efficiency estimates. MAIN OUTCOME MEASURES: Changes in NEI-RQL scales (clarity of vision, expectations, near vision, far vision, diurnal fluctuations, activity limitations, glare, symptoms, dependence on correction, worry, suboptimal correction, appearance, and satisfaction with correction). RESULTS: For myopes and hyperopes combined, refractive surgical correction was associated with statistically significant (P<0.05) improvements in scores for 11 of 13 scales. The largest improvements, ranging from 26 to 58 points on the 0 to 100 possible score range, were seen in expectations, activity limitations, dependence on correction, appearance, and satisfaction with correction. Separate analysis of myopes and hyperopes revealed similar effects in the 2 groups. Baseline scores were found to be predictive of change after surgery. CONCLUSIONS: The NEI-RQL is responsive to changes in vision-targeted health-related quality of life resulting from keratorefractive surgery. This instrument may prove useful for evaluating the beneficial and adverse impacts of surgical and nonsurgical methods of refractive error correction.

Do health care ratings differ by race or ethnicity?

BACKGROUND: There is growing evidence that Asians and Pacific Islanders perceive their health care more negatively than whites and other racial and ethnic subgroups. This study of differences in health care experiences by race and ethnicity was the first to use nationally representative data. METHODS: Data from the 1998 National Research Corporation Healthcare Market Guide survey were analyzed. A total of 120,855 respondents were included in the study. Four global satisfaction ratings (overall health plan satisfaction, medical care satisfaction, recommend plan to others, and intent to switch plans) and four composite measures (access to care, providers' delivery of care, customer service, and cost/benefits of care) were examined. RESULTS: Nonwhite survey respondents--particularly those in the other/multiracial and Asian/Pacific Islander groups--rated their health plan coverage and medical care lower than whites. DISCUSSION: The results of this study are consistent with those of other recent (and comparable) studies in which these racial and ethnic groups are represented. Most strikingly consistent, however, are the lower ratings of Asians/Pacific Islanders and the comparable (and higher) ratings (compared to whites) of African Americans. Why Asians/Pacific Islanders are considerably less satisfied with their medical care than all other racial and ethnic groups in the United States needs to be explored. Access to care and quality of care improvement efforts should be directed at all ethnic minority groups, particularly for limited English-speaking, other/multiracial, Hispanic, and Asian/Pacific Islander subgroups.

Responsiveness of the quality of life in epilepsy inventory (QOLIE-89) in an antiepileptic drug trial.

This study examined relationships among responsiveness indices for health-related quality of life (HRQOL) measures administered to adults with epilepsy enrolled in an antiepileptic drug trial. The Quality of Life in Epilepsy (QOLIE)-89 was completed at baseline and at a 28-week follow-up. Six responsiveness indices (effect size (ES), standardized response mean (SRM), responsiveness statistic, paired t-test, area under receiver operating characteristic curve or ROC, F-statistic) were calculated for each of the 16 QOLIE-89 scales, using two different external criteria for clinically significant change: (1) attainment of freedom from seizures with altered awareness, and (2) a two-category improvement between baseline and follow-up in a self-rating of the subject's overall condition. Spearman correlations among the six responsiveness indices for the 16 QOLIE-89 scales tended to be moderate to large (Spearman's p = 0.53-1.00; p's < 0.05 for 29 out of the 30 correlations). Rankings of the 16 scales across the two external criteria for change were similar for the responsiveness statistic (Spearman's p = 0.62; p < 0.05), but dissimilar for the other responsiveness indices (all p > 0.05). Both ES and SRM were well predicted by the other indices, except for ROC, using regression modeling. In conclusion, results using different responsiveness indices are comparable for a given external criterion. However, only the responsiveness statistic yielded robust results across two different external criteria. Responsiveness of this HRQOL measure can be reported in terms of previously established benchmarks for ESs, which can be predicted from other indices.

Patterns of coping among persons with HIV infection: configurations, correlates, and change.

This study examines coping in response to HIV infection, using longitudinal data from a nationally representative sample (n = 2,864) of HIV-infected persons. We investigated configurations of coping responses, the correlates of configuration membership, the stability of coping configurations, and the relationship of coping to emotional well-being. Four coping configurations emerged from cluster analyses: relatively frequent use of blame-withdrawal coping, frequent use of distancing, frequent active-approach coping, and infrequent use of all three coping strategies ("passive" copers). Passive copers had few symptoms, high levels of physical functioning, and high emotional well-being; blame-withdrawal copers had the opposite pattern. Of those completing a second interview 1 year after baseline, 46% had the same coping configuration. Increases in the number of HIV-related symptoms raised the probability of blame-withdrawal coping at follow-up, whereas decreases raised the probability of passive coping. Infrequent use of coping responses at baseline was related to greater emotional well-being 1 year later. This result, in conjunction with the high levels of emotional well-being in the passive cluster, suggests that high levels of distress can induce blame-withdrawal coping whereas coping efforts are minimal when social support and emotional well-being are high. Results highlight issues in ascertaining the causal direction between coping and psychological outcomes, as well as in specifying the nature of stressful situations with which people are coping.

Do differences in methods for constructing SF-36 physical and mental health summary measures change their associations with chronic medical conditions and utilization?

BACKGROUND AND OBJECTIVE: Various approaches have been employed to derive physical health and mental health summary scores for the SF-36 and the RAND-36, but head-to-head comparisons of alternative scoring algorithms are rare. We determined whether the associations of the physical and mental health summary scores with chronic medical conditions and utilization would differ depending on the scoring algorithm used. METHODS: We examined 5701 patients receiving medical care from an independent association of 48 physician groups located primarily in the western United States and compared SF-36 and RAND-36 scoring of physical health and mental health summary scores. Associations with the presence of diabetes, heart disease, and kidney disease, as well as with utilization of medical care and mental health care were compared using bivariate and multivariate analysis. To examine the relationship between SF-36 and RAND-36 scores, we regressed the SF-36 physical and mental health composite scores on the RAND-36 physical and mental health summary measures and vice versa. RESULTS: We found that the SF-36 and RAND-36 summary scores generally yielded results similar to one another across measures of heart disease, diabetes, and kidney disease, as well as measures of utilization. However, for each chronic medical condition, the RAND-36 showed a slightly larger decrement in mental health than did the SF-36. CONCLUSIONS: Differences between the two sets of summary scores were consistent with their respective conceptual and analytic approaches. Where comparisons of results between the SF-36 and RAND-36 summary scores are desirable in future studies, they can be estimated using the regression equations derived in this study.

Bias in assessment of health-related quality of life in a hemodialysis population: a comparison of self-administered and interviewer-administered surveys in the HEMO study.

ABSTRACT. Examined is the relationship of patient-reported health-related quality of life (HRQOL) to the mode of survey administration in the Hemodialysis Study. In addition to self-administered surveys to assess HRQOL, interviewer-administered surveys were made available to include patients with poor vision, decreased manual dexterity, or strong preference. For examining the predictors of participation by self-administration of the survey, multiple logistic regression was performed. For examining the relationship of HRQOL results to mode of survey administration, adjusted differences between the self-administered and interviewer-administered groups were obtained from multiple linear regression models accounting for sociodemographic and case-mix factors. A total of 978 of the first 1000 subjects in the Hemodialysis Study completed the survey by interview (n = 427) or by self-administration (n = 551). The interviewer-administered group was older, was more likely black, had longer duration of ESRD, had a higher prevalence of diabetes, and had more severe comorbidity (all P < 0.01). After adjustment for these differences, patients in the interviewer-administered group had higher scores on scales that measured Role-Physical, Role-Emotional, and Effects of Kidney Disease (all P < 0.001). Dialysis studies that restrict HRQOL measurement to patients who are able to complete surveys without assistance will not accurately represent the health of the overall hemodialysis population. Clinical studies and clinical practices using HRQOL as an outcome should include interviewer administration or risk a selection bias against subjects with older age, minority status, and higher level of comorbidity. Future investigation should include research of survey modalities with a low response burden such as telephone interview, computer-assisted interview, and proxy administration.

Race/ethnicity, language, and patients' assessments of care in Medicaid managed care.

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.
