Abstract
Objective Black/African American people have long reported high, albeit warranted, distrust of the US health care system (HCS); however, Blacks/African Americans are not a homogenous racial/ethnic group. Little information is available on how the subgroup of Black Americans whose families suffered under US chattel slavery, here called Descendants of Africans Enslaved in the United States (DAEUS), view health care institutions. We compared knowledge of unethical treatment and HCS distrust among DAEUS and non-DAEUS. Design and Setting A cross-sectional random-digit dialing survey was administered in 2005 to Blacks/African Americans, aged 21-75 years, from the University of Pennsylvania Clinical Practices in Philadelphia, Penn. Participants Blacks/African Americans self-reported a family history of persons enslaved in the US (DAEUS) or no family history of persons enslaved in the US (non-DAEUS). Main Outcome Measures HCS distrust was measured by a validated scale assessing perceptions of unethical experimentation and active or passive discrimination. Methods We compared responses to the HCS distrust scale using Fisher's exact and t-tests. Results Of 89 respondents, 57% self-reported being DAEUS. A greater percentage of DAEUS reported knowledge of unethical treatment than non-DAEUS (56% vs 21%; P<.001), were significantly more likely to express distrust, and to endorse the presence of covert (eg, insurance-based) than overt forms (eg, race-based) of discrimination by the HCS. Conclusions DAEUS express greater HCS distrust than non-DAEUS, patterned by awareness of unethical treatment and passive discrimination. Understanding how long-term exposure to US institutions influences health is critical to resolving disparities for all Black/African American groups. Rectifying past injustices through reparative institutional measures may improve DAEUS' trust and engagement with the US HCS.

Parast L, Griffin BA. Quantifying the bias due to observed individual confounders in causal treatment effect estimates. Stat Med 2020; 39:2447-2476. [PMID: 32388870 DOI: 10.1002/sim.8549] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Revised: 03/25/2020] [Accepted: 03/25/2020] [Indexed: 11/10/2022]
Abstract
It is often of interest to use observational data to estimate the causal effect of a target exposure or treatment on an outcome. When estimating the treatment effect, it is essential to appropriately adjust for selection bias due to observed confounders using, for example, propensity score weighting. Selection bias due to confounders occurs when individuals who are treated are substantially different from those who are untreated with respect to covariates that are also associated with the outcome. A comparison of the unadjusted, naive treatment effect estimate with the propensity score adjusted treatment effect estimate provides an estimate of the selection bias due to these observed confounders. In this article, we propose methods to identify the observed covariate that explains the largest proportion of the estimated selection bias. Identification of the most influential observed covariate or covariates is important in resource-sensitive settings where the number of covariates obtained from individuals needs to be minimized due to cost and/or patient burden and in settings where this covariate can provide actionable information to healthcare agencies, providers, and stakeholders. We propose straightforward parametric and nonparametric procedures to examine the role of observed covariates and quantify the proportion of the observed selection bias explained by each covariate. We demonstrate good finite sample performance of our proposed estimates using a simulation study and use our procedures to identify the most influential covariates that explain the observed selection bias in estimating the causal effect of alcohol use on progression of Huntington's disease, a rare neurological disease.

Abstract
Importance Considerable variation exists with respect to the profiles of patients who receive cataract surgery in the United States. Objective To identify patient characteristics associated with receiving cataract surgery within the US Medicare and Veterans Health Administration (VHA) populations. Design, Setting, and Participants In this population-based retrospective cohort study of 3 073 465 patients, Medicare and VHA patients with a cataract diagnosis between January 1, 2002, and January 1, 2012, were identified from the 2002-2012 Medicare Part B files (5% sample) and the VHA National Patient Care Database. Patient age, sex, race/ethnicity, region of residence, Charlson Comorbidity Index (CCI) scores, and comorbidities were recorded. Cataract surgery at 1 and 5 years after diagnosis was identified. Data analysis was performed from July 1, 2016, to July 1, 2017. Main Outcomes and Measures Odds ratios (ORs) of cataract surgery for selected patient characteristics. Results The study sample included 1 156 211 Medicare patients (mean [SD] age, 73.7 [7.0] years) and 1 917 254 VHA patients (mean [SD] age, 66.8 [10.2] years) with a cataract diagnosis. Of the 1 156 211 Medicare patients, 407 103 (35.2%) were 65 to 69 years old, 683 036 (59.1%) were female, and 1 012 670 (87.6%) were white. Of the 1 917 254 VHA patients, 905 455 (47.2%) were younger than 65 years, 1 852 158 (96.6%) were male, and 539 569 (28.1%) were white. A greater proportion of Medicare patients underwent cataract surgery at 1 year (Medicare: 213 589 [18.5%]; VHA: 120 196 [6.3%]) and 5 years (Medicare: 414 586 [35.9%]; VHA: 240 884 [12.6%]) after diagnosis. Factors associated with the greatest odds of surgery at 5 years were older age per 5-year increase (Medicare: OR, 1.24 [95% CI, 1.23-1.24]; VHA: OR, 1.18 [95% CI, 1.17-1.18]), residence in the southern United States vs eastern United States (Medicare: OR, 1.38 [95% CI, 1.36-1.40]; VHA: OR, 1.40 [95% CI, 1.38-1.41]), and presence of chronic pulmonary disease (Medicare: OR, 1.26 [95% CI, 1.24-1.27]; VHA: OR, 1.40 [95% CI, 1.38-1.41]). Within Medicare, female sex was associated with greater odds of surgery at 5 years (OR, 1.14; 95% CI, 1.13-1.15). Higher CCI scores (CCI score ≥3 vs 0-2) were associated with increased odds of surgery among VHA but not Medicare patients at 5 years (Medicare: OR, 0.94 [95% CI, 0.92-0.95]; VHA: OR, 1.24 [95% CI, 1.23-1.36]). Black race vs white race was associated with decreased odds of cataract surgery 5 years after diagnosis (Medicare: OR, 0.79 [95% CI, 0.78-0.81]; VHA: OR, 0.75 [95% CI, 0.73-0.76]). Conclusions and Relevance Within both groups, older age, residence in the southern United States, and presence of chronic pulmonary disease were associated with increased odds of cataract surgery. Findings from this study suggest that few disparities exist between the types of patients receiving cataract surgery who are in Medicare vs the VHA, although it is possible that a smaller proportion of VHA patients receive surgery compared with Medicare patients.

Abstract
U.S. military veterans are a large and racially heterogeneous population. There are reasons to expect that racial disparities in mortality among veterans are smaller than those for non-veterans. For example, blacks are favorably selected into the military, receive relatively equitable treatment within the military, and after service accrue higher socioeconomic status and receive health and other benefits after service. Using the 1997-2009 National Health Interview Survey (N = 99,063) with Linked Mortality Files through the end of 2011 (13,691 deaths), we fit Cox proportional hazard models to estimate whether racial disparities in the risk of death are smaller for veterans than for non-veterans. We find that black/white disparities in mortality are smaller for veterans than for non-veterans, and that this is explained by the elevated socioeconomic resources of black veterans relative to black non-veterans. Leveraging birth cohort differences in military periods, we document that the smaller disparities are concentrated among All-Volunteer era veterans.

Abstract
BACKGROUND Few studies have examined comprehensively racial/ethnic variations in quality of end-of-life care. OBJECTIVE Examine end-of-life care quality received by Veterans and their families, comparing racial/ethnic minorities to nonminorities. RESEARCH DESIGN This is a retrospective, cross-sectional analysis of chart review and survey data. SUBJECTS Nearly all deaths in 145 Veterans Affairs Medical Centers nationally (n=94,697) in addition to Bereaved Family Survey (BFS) data (n=51,859) from October 2009 to September 2014. MEASURES Outcomes included 15 BFS items and 4 indicators of high-quality end-of-life care, including receipt of a palliative care consult, chaplain visit, bereavement contact, and death in hospice/palliative care unit. Veteran race/ethnicity was measured via chart review and defined as non-Hispanic white, non-Hispanic black, Hispanic, or other. RESULTS In adjusted models, no differences were observed by race/ethnicity in receipt of a palliative care consult or death in a hospice unit. Although black Veterans were less likely than white Veterans to receive a chaplain visit, Hispanic Veterans were more likely than white Veterans to receive a chaplain visit and to receive a bereavement contact. Less favorable outcomes for racial/ethnic minorities were noted on several BFS items. In comparison with family members of white Veterans, families of minority Veterans were less likely to report excellent overall care, and this difference was largest for black Veterans (48% vs. 62%). CONCLUSIONS Bereaved family members of minority Veterans generally rate the quality of end-of-life care less favorably than those of white Veterans. Family perceptions are critical to the evaluation of equity and quality of end-of-life care.

Abstract
BACKGROUND One of the consequences of migration is cultural diversity in various communities. This has created challenges for healthcare systems. OBJECTIVES The aim of this study is to explore the health care staffs' experience of caring for Immigrants in Mashhad- Iran. SETTING This study is done in Tollab area (wherein most immigrants live) of Mashhad. Clinics and hospitals that immigrants had more referral were selected. PARTICIPANTS Data were collected through in-depth interviews with medical and nursing staffs. 15 participants (7 Doctors and 8 Nurses) who worked in the more referred immigrants' clinics and hospitals were entered to the study. DESIGN This is a qualitative study with content analysis approach. Sampling method was purposive. The accuracy and consistency of data were confirmed. Interviews were conducted until no new data were emerged. Data were analyzed by using latent qualitative content analysis. RESULTS The data analysis consisted of four main categories; (1) communication barrier, (2) irregular follow- up, (3) lack of trust, (4) cultural- personal trait. CONCLUSION Result revealed that health workers are confronting with some trans- cultural issues in caring of immigrants. Some of these issues are related to immigration status and some related to cultural difference between health workers and immigrants. These issues indicate that there is transcultural care challenges in care of immigrants among health workers. Due to the fact that Iran is the context of various cultures, it is necessary to consider the transcultural care in medical staffs. The study indicates that training and development in the area of cultural competence is necessary.

Abstract
Racial, ethnic, and gender disparities in health outcomes are a major challenge for the US health care system. Although the causes of these disparities are multifactorial, unconscious bias on the part of health care providers plays a role. Unconscious bias occurs when subconscious prejudicial beliefs about stereotypical individual attributes result in an automatic and unconscious reaction and/or behavior based on those beliefs. This article reviews the evidence in support of unconscious bias and resultant disparate health outcomes. Although unconscious bias cannot be entirely eliminated, acknowledging it, encouraging empathy, and understanding patients' sociocultural context promotes just, equitable, and compassionate care to all patients.

Abstract
Homelessness [and poverty] is rapidly escalating across North America and is associated with dire implications for public health and our health care systems. Both are compelling states of existence affecting all ages, ethnicities and both genders. Homelessness frequently evolves through a complex interaction of factors that are both internal and external to the individual themselves. Once homeless, equitable access to both preventative and remedial health care is lacking and is associated with a higher than average burden of cardiovascular disease [CVD] risk factors, morbidity and mortality and is accompanied by disproportionately high health care costs. The emergence of limited, small scale programs aimed at addressing the unique health and social needs of the homeless is encouraging. However, there has been inadequate commitment at the National, State or Provincial and local levels to implement policies and dedicate funding and resources to the expansion of such “individual level” interventions into comprehensive programs that deliver sustainable, integrated prevention and services, especially with regard to CVD. The long-term solutions that address the links between homelessness and CVD lie in preventing homelessness and reversing the trends in our health care system that create disparities for lower socioeconomic status [SES] and homeless individuals.

Abstract
BACKGROUND As a result of the impact of health disparities on the healthcare system such as their influence on arenas significant to healthcare distribution, including cost, quality, and access, identification and resolution of health disparities is a primary national agenda item. Resolution of disparities in amputation is an area of opportunity that warrants further consideration. QUESTIONS/PURPOSES The purposes of our review are to highlight current data on disparities in amputation in minorities and to consider future goals related to an elimination of this disparity. METHODS Studies on disparities in amputation were accessed using the following databases: PubMed, Cinahl, OVID/Medline, Embase, and Cochrane databases. In each database, a search of title/abstract was performed for the search terms "disparities and amputation," "race and amputation," and "diabetes and amputation." Each search was limited by human and English language. Where are we now? A disparity exists in both frequency and level of amputation in minorities both in the presence and absence of a diagnosis of diabetes. Where do we need to go? A need exists for future research involving a more deliberate examination of the use of preventive screening for patients at high risk for amputation across medical settings. How do we get there? Research in this area would benefit from funding, large-scale data collection, and physician exposure to education on high-risk patients and preventive screening opportunities.

Abstract
BACKGROUND There is growing concern over the impact of accelerating use of diagnostic imaging services on health care spending. Echocardiography is an important cardiovascular imaging procedure, but little is known about trends in its use or utilization. We examine trends in the utilization of echocardiography in a national health care system. METHODS We used administrative data from the Veterans Healthcare Administration (VA) from 2000 to 2007 to identify patients receiving regular medical care (VA users) or echocardiograms at the VA. We then examined the number of echocardiograms performed each year within the VA and echocardiogram utilization (rates per 1,000 VA users). We examined changes in echocardiogram use and utilization over time and potential overuse of echocardiography. RESULTS The number of echocardiograms increased from 92,269 in 2000 to 195,767 in 2007 (a 112.2% increase). Alternatively, echocardiogram utilization remained relatively stable, increasing from 68.8 per 1,000 VA users in 2000 to 71.5 per 1,000 VA users in 2007 because the number of VA users increased by 104.2% over the study period. The mean number of scans per year in echocardiogram recipients remained constant at 1.1/y, and the proportion of recipients receiving multiple scans remained constant at <10%. CONCLUSIONS Use of echocardiography in the VA increased dramatically between 2000 and 2007, but utilization rates increased only modestly. Our results suggest that, within the VA, growth in the use of echocardiography resulted from an increase in the number of patients receiving care from the VA on regular basis rather than the performance of a greater number of echocardiograms on a fixed patient population.

Abstract
Longstanding racial/ethnic disparities exist in the USA in the areas of healthcare access, healthcare utilization and health-related outcomes of chronic health conditions, such as stroke. Regarding stroke specifically, significant racial/ethnic disparities in stroke incidence, severity and outcomes have been reported. Despite these differences, little attention has been given to potential racial/ethnic differences in the utilization of rehabilitation services for patients after stroke. To date, only a few studies have been specifically designed to examine racial/ethnic differences in rehabilitation service utilization. A review of these studies and related studies suggests that racial/ethnic differences may be present in the utilization of poststroke rehabilitation services. Consequently, new studies are needed to delineate how race/ethnicity influences utilization of poststroke rehabilitation services and to determine how a reduction in this disparity gap could improve stroke-related outcomes among racial/ethnic minorities in the USA.

Abstract
BACKGROUND Stage at diagnosis plays a significant role in colorectal cancer (CRC) survival. Understanding which factors contribute to a more advanced stage at diagnosis is vital to improving overall survival. Comorbidity, race, and age are known to impact receipt of cancer therapy and survival, but the relationship of these factors to stage at diagnosis of CRC is less clear. The objective of this study is to investigate how comorbidity, race and age influence stage of CRC diagnosis. METHODS Two distinct healthcare populations in the United States (US) were retrospectively studied. Using the Cancer Care Outcomes Research and Surveillance Consortium database, we identified CRC patients treated at 15 Veterans Administration (VA) hospitals from 2003-2007. We assessed metastatic CRC patients treated from 2003-2006 at 10 non-VA, fee-for-service (FFS) practices. Stage at diagnosis was dichotomized (non-metastatic, metastatic). Race was dichotomized (white, non-white). Charlson comorbidity index and age at diagnosis were calculated. Associations between stage, comorbidity, race, and age were determined by logistic regression. RESULTS 342 VA and 340 FFS patients were included. Populations differed by the proportion of patients with metastatic CRC at diagnosis (VA 27% and FFS 77%) reflecting differences in eligibility criteria for inclusion. VA patients were mean (standard deviation; SD) age 67 (11), Charlson index 2.0 (1.0), and were 63% white. FFS patients were mean age 61 (13), Charlson index 1.6 (1.0), and were 73% white. In the VA cohort, higher comorbidity was associated with earlier stage at diagnosis after adjusting for age and race (odds ratio (OR) 0.76, 95% confidence interval (CI) 0.58-1.00; p = 0.045); no such significant relationship was identified in the FFS cohort (OR 1.09, 95% CI 0.82-1.44; p = 0.57). In both cohorts, no association was found between stage at diagnosis and either age or race. CONCLUSION Higher comorbidity may lead to earlier stage of CRC diagnosis. Multiple factors, perhaps including increased interactions with the healthcare system due to comorbidity, might contribute to this finding. Such increased interactions are seen among patients within a healthcare system like the VA system in the US versus sporadic interactions which may be seen with FFS healthcare.

Abstract
INTRODUCTION Although women will account for almost 11% of veterans by 2040, we know little about their health and functioning, particularly compared to men. OBJECTIVE To compare women and men veterans' health-related quality of life (HRQOL) and VA health care utilization and to see if previously described associations between HRQOL, subsequent VA health care utilization, and mortality in male veterans would generalize to women veterans. METHODS Prospective cohort study of all veterans who received medical care from an Upper Midwest Veterans Affairs facility between 10/1/96 and 3/31/98 and returned a mailed questionnaire. RESULTS Women's effective survey response rate was 52% (n = 1,500); men's, 58% (n = 35,000). In the following year, 9% of women and 12% of men had at least one hospitalization. One percent of women and 3% of men died in the post-survey year. After adjustment, women's HRQOL was higher than men's; for every 10-point decrement in overall physical or mental functioning, women and men had similarly increased risk/odds of subsequently dying, being hospitalized at a VA facility, or making a VA outpatient stop. Among younger women and women who received VA care outside of the Twin City metro area, poorer overall mental or physical health functioning was associated with fewer primary care stops; among their male counterparts, it was associated with more primary care stops. CONCLUSION Compared to men, women veterans receiving VA health care in the upper Midwest catchment area had better HRQOL and used fewer health services. Although VA health care utilization was similar across gender after adjusting for HRQOL, poorer mental or physical health was associated with fewer primary care stops for selected subgroups of women.

Abstract
OBJECTIVE To study the accuracy of diagnoses of spondylarthritides in computerized databases at the Minneapolis Veterans Affairs Medical Center. METHODS Medical records were available and reviewed for a random sample of 184 patients from a cohort of 737 patients seen at the rheumatology clinic between January 1, 2001 and July 31, 2002. We compared 4 database definitions with the medical record gold standard of rheumatologists' diagnosis of ankylosing spondylitis (AS), psoriatic arthritis (PsA), or reactive arthritis (ReA): presence of 1) > or =1 or 2) > or =2 International Classification of Diseases, Ninth Revision (ICD-9) diagnostic codes for diagnoses of AS (720.0), PsA (696.0), and ReA (099.3, 711.11-711.19), and presence of 3) > or =1 or 4) > or =2 ICD-9 codes and prescription of a disease-modifying antirheumatic drug (DMARD). Accuracy was assessed by sensitivity, specificity, positive predictive values (PPVs) and negative predictive values (NPVs), kappa statistic, and receiver operator characteristic (ROC) curve area. RESULTS Of 184 patients, 11 (6%) had AS, 17 (9%) had PsA, and 7 (4%) had ReA as per the gold standard. ICD-9 codes for AS, PsA, and ReA were very specific (98-100%) with excellent NPV (99-100%) and PPV (83-100%), good to excellent sensitivity (57-100%), almost perfect kappa agreement (0.72-1), and high ROC curve area (0.79-1). Addition of presence of DMARD prescription to ICD-9 codes of AS and PsA decreased sensitivity to 27-65% without improving the specificity (which was already high at 99-100%). CONCLUSION The ICD-9 codes for AS, PsA, and ReA in databases are accurate. ICD-9 codes may be used to identify cohorts of patients with spondylarthritides.

Abstract
We examined the effects of use of low charge, integrated and comprehensive health care services (Veterans Administration (VA) health care system) on health care service use and health-related outcomes. Data came from the 10-year (1986/87-1996/97) Duke Established Populations for Epidemiologic Studies of the Elderly, with 159 men aged 65-85 who primarily used VA health services compared with 1,100 men aged 65-85 who did not. In controlled analyses, no differences were found between the two groups on number of OTC medications used, or in speed or likelihood of entering a nursing home. However, veterans who primarily used the VA health care system reported more outpatient visits and prescription drugs, and increased likelihood of using an adjunct health care provider; entry into a hospital was quicker, and number of hospitalizations was greater. Although health status was controlled, because of eligibility requirements it remains possible that veterans were sicker. Nevertheless, no differences were found in health outcome (functional status or mortality). Readier access to better integrated health services appears to result in increased use of health services controlled by the health care provider, but not of services requiring the recipient's relocation, while functional status and mortality attained equivalence.

Abstract
BACKGROUND Racial/ethnic differences in influenza vaccination exist among elderly adults despite nearly universal Medicare health insurance coverage. Overall influenza vaccination prevalence in the Veterans Affairs (VA) Healthcare System is higher than in the general population; however, it is not known whether racial/ethnic differences exist among older adults receiving VA healthcare. Racial/ethnic differences in influenza vaccination in VA were assessed, and barriers to and facilitators of influenza vaccination were examined among veteran outpatients aged 50 years and older. METHODS A random sample of 121,738 veterans receiving care at VA outpatient clinics during the 2003-2004 influenza season completed the mailed Survey of Health Experiences of Patients (77% response rate). Multivariate logistic regression was used to examine associations among race/ethnicity and influenza vaccination prevalence, barriers, and facilitators. Analyses were conducted during 2005 and 2006. RESULTS Based on unadjusted prevalences, non-Hispanic blacks, Hispanics, and American Indian/Alaskan Natives were significantly less likely to be vaccinated for influenza compared to non-Hispanic whites (71%, 79%, and 74%, respectively, vs 82%). After adjustment for age, gender, marital status, education level, employment, having a primary care provider, confidence and/trust in provider, and health status, only non-Hispanic blacks remained significantly less likely to be vaccinated compared to non-Hispanic whites (75% vs 81%). Influenza vaccination barriers and facilitators varied by race/ethnic group. CONCLUSIONS Compared to non-Hispanic whites, non-Hispanic blacks were less likely to receive influenza vaccination in the VA healthcare system during the 2003-2004 influenza season. Although these differences were small, results suggest the need for further study and culturally informed interventions.

Abstract
BACKGROUND Few recent studies have demonstrated similar quality of care for hospitalized black and white patients with heart failure (HF). However, systematic evaluation of racial differences in both the quality of care and outcomes is needed in the outpatient setting, where most patients with HF are treated and where care may be more fragmented. METHODS We examined racial differences in quality-of-care measures and outcomes of 1-year mortality and hospitalization in a national cohort of 18,611 ambulatory patients with HF treated at Veterans Affairs medical centers between October 2000 and September 2002. RESULTS Black patients were more likely to have left ventricular ejection fraction assessment than whites (risk-adjusted OR 1.29, 95% CI 1.11-1.49). In patients with left ventricular ejection fraction <40%, blacks were as likely as whites to be on treatment with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (risk-adjusted OR 1.06, 95% CI 0.85-1.33) and beta-blockers (risk-adjusted OR 0.92, 95% CI 0.79-1.07). However, black patients more frequently had uncontrolled hypertension and were more likely to be hospitalized for any cause (OR 1.20, 95% CI 1.08-1.33) or for HF (OR 1.43, 95% CI 1.23-1.66), although 1-year mortality did not differ by race (OR 1.03, 95% CI 0.89-1.20). CONCLUSIONS In a financially "equal access" health care system, the quality of outpatient HF care assessed by select quality measures and 1-year mortality was similar in black compared to white patients. However, blacks were more likely to be hospitalized, especially with HF. Identifying and targeting potentially modifiable factors such as uncontrolled hypertension in black patients may narrow the racial gap in hospitalizations.

Abstract
OBJECTIVE We sought to examine differences in valuation of health by individuals from different ethnic backgrounds and between patients and community members. RESEARCH DESIGN We surveyed 193 community members identified by random-digit dialing (ie, 64 white, 65 black, and 64 Hispanic) and 198 patients with osteoarthritis (OA), 66 per ethnic group, drawn sequentially from clinic lists of an outpatient institution. MEASURES Participants were interviewed and asked to rate 2 scenarios describing arthritis (mild and severe) using visual analog scale (VAS), standard gamble (SG), and time trade-off (TTO). Differences were adjusted for cohort, age, gender, and education. RESULTS Members of the public had higher preference scores for the 2 health states than patients (SG severe state: 0.77 public, 0.66 patients; SG mild state: 0.90 public, 0.84 patients). The difference score between the mild and severe states was smaller for black than white subjects (P < 0.001) by SG and TTO. Scores for Hispanics and whites did not differ. Preference scores increased with age (SG, TTO). CONCLUSIONS Significant differences were observed in the valuation of health between members of the public and patients, among ethnic groups, and in relation to educational status and age, with the difference between utilities of health states being a more efficient measure of preference than the utility of a single state. Utilities elicited through valuation of hypothetical health scenarios are dependent on sociodemographic traits, experience of disease, and method used. These findings suggest that utilities cannot be used interchangeably across populations, with implications for economic analyses.

Abstract
OBJECTIVE To determine the accuracy of International Classification of Diseases (ICD) code 714 for rheumatoid arthritis (RA) diagnosis in a Veterans Administration (VA) hospital database and to examine the effects of adding laboratory and pharmacy data to ICD code 714 on accuracy of RA diagnosis. METHODS We drew a random sample of patients from all Minneapolis VA rheumatology clinic patients who had at least 1 rheumatology clinic visit between January 2001 and July 2002. Charts of 184 patients were reviewed. The gold standard for RA diagnosis was chart documentation of RA diagnosis by a rheumatologist on > or =2 visits >6 weeks apart. The data definitions of RA diagnosis included presence of ICD code 714 alone or various combinations of ICD code 714, a positive rheumatoid factor (RF), and prescription for a disease-modifying antirheumatic drug (DMARD). Accuracy of data definitions of RA was assessed by calculating sensitivity, specificity, positive and negative predictive values, and area under the receiver operator characteristics curve. RESULTS Diagnosis by ICD code 714 had 100% sensitivity, but specificity was only 55% because of a false-positive rate of 34%. The addition of a positive RF and/or a DMARD prescription to ICD code 714 dramatically improved specificity to 83-97% and positive predictive value to 81-97%; however, sensitivity decreased to 76-88%. Diagnosis by ICD 714 alone had the highest negative predicative value of 100%. The area under the curve was the greatest when both ICD code 714 and a positive RF were included, and the least when ICD code alone was used. CONCLUSION ICD code 714 in the VA administrative database is a very sensitive screening tool for identifying patients with RA in the rheumatology clinic population. Addition of the presence of a DMARD prescription and/or a positive RF to selection criteria improves specificity of the diagnosis.

Abstract
There is a growing need for geropsychologists who are specialists in practice, research, education, and advocacy for older adults. The combined USF/Tampa VA geropsychology fellowship program focuses on the training of three post-doctoral Fellows each year in public sector service delivery across diverse long term care (LTC) and primary care settings. Addressing the bio-psycho-social needs of frail, poor, and minority older adults within an interdisciplinary framework exposes geropsychology Fellows to the complex nature of mental health problems of older adults and the need for collaborative efforts across professional lines. The program builds on prior geropsychology training at the graduate and internship levels by providing an integrated framework to achieve clinical, didactic, program evaluation, and advocacy goals: (1) delivery of state-of-the-art evidence-based psychological services to disadvantaged older adults in geriatric public sector primary care sites; (2) mastery of the knowledge base on diversity and interdisciplinary teamwork as they relate to providing services to older adults, including those residing in rural areas; (3) gaining competence in the evaluation of services to disadvantaged older adults; and (4) experience in public health advocacy for improvement of the LTC system.

Abstract
OBJECTIVES We examined whether racial differences exist in cholesterol monitoring, use of lipid-lowering agents, and achievement of guideline-recommended low-density lipoprotein (LDL) levels for secondary prevention of coronary heart disease. METHODS We reviewed charts for 1045 African American and White patients with coronary heart disease at 5 Veterans Affairs (VA) hospitals. RESULTS Lipid levels were obtained in 67.0% of patients. Whites and African Americans had similar screening rates and mean lipid levels. Among the 544 ideal candidates for therapy, rates of treatment and achievement of target LDL levels were similar. CONCLUSIONS We found no disparities in cholesterol management. This absence of disparities may be the result of VA quality improvement initiatives or prescription coverage through the VA health care system.

Abstract
OBJECTIVE We sought to determine the accuracy of administrative data for identifying mental health service provision in primary care. STUDY DESIGN This was a chart abstraction study measuring agreement between billing data and clinical data on the binary variable "mental health visit." Data were collected from the charts and billing records of 5 academic family practice clinics in Toronto, Ontario (1999 to 2000). Billing claims (n = 952) were selected from the billings for all visits by a stratified random sampling technique. A blinded data abstractor reviewed the clinical charts and assigned diagnostic codes for each patient visit associated with the selected claims. Any visit with at least 1 abstracted mental health diagnostic code was defined as a mental health visit. The test characteristics of 4 administrative measures of mental health service provision, based on different combinations of billing codes, were calculated. RESULTS The accuracy of the administrative data was 86.8% when compared with clinical data. The sensitivity of the 4 administrative measures ranged from 22.3% to 80.7%. The specificity ranged from 97.0% to 99.5%. CONCLUSIONS This is the first study to establish the performance of administrative data in measuring mental health service provision in a primary care setting. In our setting, broadly defined administrative measures of mental health have excellent specificity and adequate sensitivity for exploring and understanding mental health service utilization.

Abstract
BACKGROUND Differential diagnosis of schizophrenia and bipolar disorder is a challenging but important task. These conditions often exhibit overlapping clinical symptomatology, but have different prognoses and pharmacological management strategies. Factors other than clinical presentation may influence diagnosis. Past studies suggest that ethnicity is one such factor, with variations observed in diagnostic rates of serious mental illness (SMI). With increasing attention paid to provider cultural competency, we investigate current diagnostic practices within a veteran population. METHOD Controlling for patient need characteristics and illness severity, we examine whether ethnic differences in diagnosis continue to exist. If so, race may adversely enter the evaluation process. A national database of all SMI veterans explores the relationship between ethnicity and diagnosis. The role of symptomatology is also examined. Given minimal variation in veteran socioeconomic status, the Department of Veterans Affairs (VA) provides a natural setting to address this confounding factor. The 1999 National Psychosis Registry provides a sample of 134,523 veterans diagnosed with schizophrenia, schizoaffective disorder, or bipolar disorder. Multinomial logistic regression yielded odds ratios (OR) for being diagnosed with schizophrenia versus bipolar disorder; the schizoaffective versus bipolar risk was likewise assessed, exploring theoretical aspects of a psychosis-affective 'continuum'. RESULTS Small effects were observed for being male, single or rural resident. However, the demographic characteristic most strongly associated with a schizophrenia diagnosis was race. The OR for African Americans was 4.05, and 3.15 for Hispanics. Similar though less dramatic results were revealed for schizoaffective disorder. CONCLUSIONS This study confirms continued ethnic disparities in diagnostic patterns, and highlights the importance of recognizing ethnic differences in symptom presentation while emphasizing greater cultural competency.

Abstract
OBJECTIVES The objectives of this study were to determine racial differences in mortality in a national cohort of patients hospitalized with congestive heart failure (CHF) within a financially "equal-access" healthcare system, the Veterans Health Administration (VA), and to examine racial differences in patterns of healthcare utilization following hospitalization. BACKGROUND To explain the observed paradox of increased readmissions and lower mortality in black patients hospitalized with CHF, it has been postulated that black patients may have reduced access to outpatient care, resulting in a higher number of hospital admissions for lesser disease severity. METHODS In a retrospective study of 4,901 black and 17,093 white veterans hospitalized with CHF in 153 VA hospitals, we evaluated mortality at 30 days and 2 years, and healthcare utilization in the year following discharge. RESULTS The risk-adjusted odds ratios (OR) for 30-day and 2-year mortality in black versus white patients were 0.70 (95% confidence interval [CI] 0.60 to 0.82) and 0.84 (95% CI 0.78 to 0.91), respectively. In the year following discharge, blacks had the same rate of readmissions as whites. Blacks had a lower rate of medical outpatient clinic visits and a higher rate of urgent care/emergency room visits than whites, although these differences were small. CONCLUSIONS In a system where there is equal access to healthcare, the racial gap in patterns of healthcare utilization is small. The observation of better survival in black patients after a CHF hospitalization is not readily explained by differences in healthcare utilization.

Abstract
BACKGROUND To determine how patient attitudes, beliefs, knowledge, and sociodemographic characteristics relate to influenza vaccine acceptance in an older patient population. METHODS We conducted a mail survey of patients enrolled in a geriatrics clinic at a university-affiliated county hospital in Seattle, WA. We surveyed senior citizens' demographic background, health status, previous experiences, and beliefs about influenza and influenza vaccine. We determined the vaccination rates for influenza season 2001-2002 stratified by race, other sociodemographic factors, and attitudes toward influenza vaccination. RESULTS Surveys were mailed to 572 enrollees in SeniorCare Clinic. Three hundred twenty-four (57%) responded to the survey, 256 (79%) of whom reported receipt of influenza vaccination. Influenza vaccination rates did not vary significantly by race in this patient population: 80% for white persons, 70% for black persons, and 84% for Asians. Receipt of vaccination was associated with survey responses that indicated a discussion about the influenza shot with a health care provider and a positive attitude toward the influenza shot. History of side effects and negative attitude toward the influenza shot were associated with failure to receive the vaccine. CONCLUSIONS In patients served by a university-affiliated geriatrics clinic, we found no statistically significant difference in influenza vaccination rate between white persons and other racial groups. Attitudes, beliefs, knowledge, and prior experiences toward the influenza shot were predictors of influenza vaccination. Physician recommendation and patient participation strongly correlated with vaccination acceptance.

Abstract
This study was conducted to identify factors accounting for differences in health care and drug treatment utilization between Puerto Rican drug users residing in 2 separate locations. Survey findings from 334 drug users in Puerto Rico and 617 in New York City showed that those in Puerto Rico were 6 times less likely than their counterparts in New York to have used inpatient medical services and 13 to 14 times less likely to have used outpatient medical services or methadone. They also were less likely to have health insurance or past drug treatment. After site was controlled for, health insurance and previous use of physical or mental health services remained significant predictors of health care and drug treatment utilization during the study period. Although Puerto Rican drug users in Puerto Rico are not an ethnic minority, they reported significant disparities in health services use compared with Puerto Rican drug users in New York.

Abstract
The present study examined levels and correlates of knowledge about osteoporosis among 176 Israeli-Jewish (mean age = 55) and 80 Israeli-Arab (mean age = 51) women. Levels of knowledge about the disease were low among all women, especially regarding some of the risk factors. Knowledge and awareness about the disease were especially deficient among Arab women. Younger age and lower education were the main vulnerability factors among Jewish women, and lower desire to seek information from the medical establishment, higher religiosity, and the lack of extended medical insurance among Arab women. Educational programs, geared to the needs and capabilities of the different ethnic populations, should be encouraged.

Abstract
BACKGROUND Black Americans with diabetes have a higher burden of illness and mortality than do white Americans. However, the extent to which differences in medical care processes and treatment intensity contribute to poorer diabetes outcomes is unknown. OBJECTIVE To assess racial disparities in the quality of diabetes care processes, intermediate outcomes, and treatment intensity. METHODS We conducted an observational study of 801 white and 115 black patients who completed the Diabetes Quality Improvement Project survey (response rate=72%) in 21 Veterans Affairs (VA) facilities using survey data; medical record information on receipt of diabetes services (A1c, low-density lipoprotein [LDL], nephropathy screen, and foot and dilated eye examinations), and intermediate outcomes (glucose control measured by A1c; cholesterol control measured by LDL; and achieved level of blood pressure); and pharmacy data on filled prescriptions. RESULTS There were no racial differences in receipt of an A1c test or foot examination. Blacks were less likely than whites to have LDL checked in the past 2 years (72% vs. 80%, P<0.05) and to have a dilated eye examination (50% vs. 63%, P<0.01). Even after adjusting for patients' age, education, income, insulin use, diabetes self-management, duration, severity, comorbidities, and health services utilization, racial disparities in receipt of an LDL test and eye examination persisted. After taking into account the nested structure of the data using a random intercepts model, blacks remained significantly less likely to have LDL testing than whites who received care within the same facility (68% vs. 83%, P<0.01). In contrast, there were no longer differences in receipt of eye examinations, suggesting that black patients were more likely to be receiving care at facilities with overall lower rates of eye examinations. After adjusting for patient characteristics and facility effects, black patients were substantially more likely than whites to have poor cholesterol control (LDL > or =130) and blood pressure control (BP > or =140/90 mm Hg) (P<0.01). Among those with poor blood pressure and lipid control, blacks received as intensive treatment as whites for these conditions. CONCLUSIONS We found racial disparities in some diabetes care process and intermediate outcome quality measures, but not in intensity of treatment for those patients with poor control. Disparities in receipt of eye examinations were the result of black patients being more likely to receive care at lower-performing facilities, whereas for other quality measures, racial disparities within facilities were substantial.

Abstract
BACKGROUND Guideline-based depression process measures provide a powerful way to monitor depression care and target areas needing improvement. OBJECTIVES To assess the adequacy of depression care in the Veterans Health Administration (VHA) using guideline-based process measures derived from administrative and centralized pharmacy records, and to identify patient and provider characteristics associated with adequate depression care. RESEARCH DESIGN This is a cohort study of patients from 14 VHA hospitals in the Northeastern United States which relied on existing databases. Subject eligibility criteria: at least one depression diagnosis during 1999, neither schizophrenia nor bipolar disease, and at least one antidepressant prescribed in the VHA during the period of depression care profiling (June 1, 1999 through August 31, 1999). Depression care was evaluated with process measures defined from the 1997 VHA depression guidelines: antidepressant dosage and duration adequacy. We used multivariable regression to identify patient and provider characteristics predicting adequate care. SUBJECTS There were 12,678 patients eligible for depression care profiling. RESULTS Adequate dosage was identified in 90%; 45% of patients had adequate duration of antidepressants. Significant patient and provider characteristics predicting inadequate depression care were younger age (<65), black race, and treatment exclusively in primary care. CONCLUSIONS Under-treatment of depression exists in the VHA, despite considerable mental health access and generous pharmacy benefits. Certain patient populations may be at higher risk for inadequate depression care. More work is needed to align current practice with best-practice guidelines and to identify optimal ways of using available data sources to monitor depression care quality.

Abstract
BACKGROUND AND OBJECTIVES This study used the Behavioral Model for Vulnerable Populations to identify determinants of receipt of outpatient medical care within 6 months of initial contact with a national homeless veterans outreach program. RESEARCH DESIGN Prospective study. SUBJECTS Homeless veterans contacted through the program in 1999 (n = 26,926). MEASURES Data from structured interviews conducted at the time of program intake were merged with Veterans Affairs administrative data to determine subsequent medical service use. Logistic regression modeling was used to identify predisposing, enabling, and need factors from traditional and vulnerable domains predictive of receiving medical care. RESULTS Overall, 41.8% of subjects received at least one medical visit in the 6 months after program intake; of these, 48.7% had three or more visits. In multivariate analyses, the likelihood of receiving medical care was, among other things, positively associated with age, female gender, and placement in residential treatment and negatively associated with duration of homelessness and being contacted through outreach versus referred or self-referred into the homeless program. Mental illness did not appear to be an additional barrier to initiating medical care; however, a diagnosis of substance abuse or schizophrenia was associated with a decreased likelihood of receiving three or more visits. CONCLUSION A majority of homeless veterans contacted through a national outreach program failed to receive medical services within 6 months of program entry. Vulnerable-domain factors were important supplements to traditional variables in predicting use of medical services in the homeless population. Greater efforts are needed to ensure that mentally ill homeless persons are successfully linked with and engaged in medical treatment.

Abstract
There is extensive evidence of racial/ethnic disparities in receipt of health care. The potential contribution of provider behavior to such disparities has remained largely unexplored. Do health and human service providers behave in ways that contribute to systematic inequities in care and outcomes? If so, why does this occur? The authors build on existing evidence to provide an integrated, coherent, and sound approach to research on providers' contributions to racial/ethnic disparities. They review the evidence regarding provider contributions to disparities in outcomes and describe a causal model representing an integrated set of hypothesized mechanisms through which health care providers' behaviors may contribute to these disparities.

Abstract
Finding ways to deliver high-quality health care to an increasingly diverse population is a major challenge for the American health care system. The persistence of racial and ethnic disparities in health care access, quality, and outcomes has prompted considerable interest in increasing the cultural competence of health care, both as an end in its own right and as a potential means to reduce disparities. This article reviews the potential role of cultural competence in reducing racial and ethnic health disparities, the strength of health care organizations' current incentives to adopt cultural competence techniques, and the limitations inherent in these incentives that will need to be overcome if cultural competence techniques are to become widely adopted.
