Associations Between Race and Survival Outcomes Among Veterans With Head and Neck Cancer in a Racially Diverse Setting. OTO Open 2024; 8:e150. [PMID: 38863487 PMCID: PMC11165679 DOI: 10.1002/oto2.150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 04/14/2024] [Accepted: 05/17/2024] [Indexed: 06/13/2024] Open
Abstract
Objective There is limited data on the impact of clinical-demographic factors on survival outcomes among veterans with head and neck squamous cell carcinoma (HNSCC). This study was undertaken to evaluate the impact of race and other factors on overall survival (OS) in a population of veterans with HNSCC treated with curative intent. Methods Demographic and clinical data were collected on veterans with HNSCC treated with curative intent at our institution between 1999 and 2021. The primary outcome was 3-year OS. Secondary outcomes included treatment delay intervals, including time to treatment initiation (TTI), total package time, and duration of chemoradiation (DCRT). Results Of 260 veterans with HNSCC, black veterans had significantly lower 3-year OS (49.4%) compared to white veterans (65%, P = .019). Black veterans were also more likely to experience delays in treatment initiation (median TTI 46 vs 41 days; P = .047). Black patients were more likely to receive radiation alone (25.8% [black] vs 8.4% [white]; P < .001) and less likely to receive adjuvant therapy if treated surgically (11.1% [black] vs 22.4% [white]; P = .004), despite any statistically significant difference in stage of their tumor at presentation (Stage I: 21.2% [black] vs 19.6% [white]; P = .372); (Stage IV: 44.4% [black] vs 48.6% [white]; P = .487). Other factors associated with worse 3-year OS included older age (P = .023), lower body mass index (P = .026), neurocognitive disorder/dementia (P = .037), mental health disorders (P = .020), hypopharyngeal primary (P = .001), higher stage disease (P = .002), treatment type (P = .001), need for prophylactic gastrostomy tube (P = .048) or tracheotomy (P = .005), recurrent disease (P = .036), persistent disease (P < .001), distant metastases (P = .002), longer TTI (P = .0362), and longer DCRT (P = .004). Discussion Black race appears to be an independent predictor of 3-year OS in veterans with HNSCC. Further studies are warranted to determine the factors responsible for disparities in survival. Implications for Practice This study evaluated the ways in which race affects survival for US veterans with head and neck cancer. The authors found that black veterans had an increased risk of death compared to white patients, and also experienced delays when receiving treatment. Level of Evidence Level IV.

Socioeconomic status fails to account for worse outcomes in non-Hispanic black patients undergoing carotid revascularization. J Vasc Surg 2023; 78:1248-1259.e1. [PMID: 37419427 PMCID: PMC10615195 DOI: 10.1016/j.jvs.2023.06.103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 06/08/2023] [Accepted: 06/28/2023] [Indexed: 07/09/2023]
Abstract
OBJECTIVE Previous studies have reported an association of Black race with worse carotid revascularization outcomes, but rarely include socioeconomic status as a confounding covariate. We aimed to assess the association of race and ethnicity with in-hospital and long-term outcomes following carotid revascularization before and after accounting for socioeconomic status. METHODS We identified non-Hispanic Black and non-Hispanic white patients who underwent carotid endarterectomy, transfemoral carotid stenting, or transcarotid artery revascularization between 2003 and 2022 in the Vascular Quality Initiative. Primary outcomes were in-hospital stroke/death and long-term stroke/death. Multivariable logistic regression and Cox proportional hazards models were used to assess the association of race with perioperative and long-term outcomes after adjusting for baseline characteristics using a sequential model approach without and with consideration of Area Deprivation Index (ADI), a validated composite marker of socioeconomic status. RESULTS Of 201,395 patients, 5.1% (n = 10,195) were non-Hispanic Black, and 94.9% (n = 191,200) were non-Hispanic white. Mean follow-up time was 3.4±0.01 years. A disproportionately high percentage of Black patients were living in more socioeconomically deprived neighborhoods relative to their white counterparts (67.5% vs 54.2%; P < .001). After adjusting for demographic, comorbidity, and disease characteristics, Black race was associated with greater odds of in-hospital (adjusted odds ratio [aOR], 1.24; 95% confidence interval [CI], 1.10-1.40) and long-term stroke/death (adjusted hazard ratio [aHR], 1.13; 95% CI, 1.04-1.23). These associations did not substantially change after additionally adjusting for ADI; Black race was persistently associated with greater odds of in-hospital (aOR, 1.23; 95% CI, 1.09-1.39) and long-term stroke/death (aHR, 1.12; 95% CI, 1.03-1.21). Patients living in the most deprived neighborhoods were at greater risk of long-term stroke/death compared with patients living in the least deprived neighborhoods (aHR, 1.19; 95% CI, 1.05-1.35). CONCLUSIONS Non-Hispanic Black race is associated with worse in-hospital and long-term outcomes following carotid revascularization despite accounting for neighborhood socioeconomic deprivation. There appears to be unrecognized gaps in care that prevent Black patients from experiencing equitable outcomes following carotid artery revascularization.

Abstract
BACKGROUND Reasons for racial disparities in the utilization and outcomes of carotid interventions (carotid endarterectomy (CEA) and carotid artery stenting (CAS)) are not well understood, especially segregation of care associated with carotid intervention. We examined patterns of geographic and provider care segregation in carotid interventions and outcomes. METHOD We used de-identified Medicare datasets to identify CEA and CAS interventions between January 1, 2016 and December 31, 2019 using validated ICD-10 codes. For patients who underwent carotid intervention, we calculated (1) the proportion of White patients at the hospital, (2) the proportional difference in the proportion of White patients between hospital patients and the county, and (3) provider care segregation by the dissimilarity index for carotid intervention cases. We examined associations between measures of segregation and outcomes. RESULTS Despite higher proportions of Black patients in counties with hospitals that provide carotid intervention, lower proportions of Black patients received intervention. The difference in the proportion of White patients comparing CEA patients to the county race distribution was 0.143 (SD 0.297) at the hospital level (for CAS, 0.174 (0.315)). The dissimilarity index for CEA providers was high, with mean (SD) 0.387 (0.274) averaged across all hospitals and higher among CAS providers at 0.472 (0.288). Black patients receiving CEA and CAS (compared with Whites) had reduced odds of discharge home. Better outcomes (inpatient mortality and 30-day mortality) were independently associated with higher proportion of White CAS patients. CONCLUSION In this national study with contemporary data on carotid intervention, we found evidence for segregation of care of both CEA and CAS.

AMERICAN HEART JOURNAL PLUS : CARDIOLOGY RESEARCH AND PRACTICE 2022; 19:100186.

Abstract
Background Implantable cardioverter-defibrillators (ICDs) reduce the risk of sudden cardiac death among patients with persistently reduced (≤35 %) left ventricular ejection fraction (LVEF) at least 40 days following acute myocardial infarction (AMI). Few prior studies have used LVEF measured after the 40-day waiting period to examine primary prevention ICD placement. Methods We sought to determine factors associated with ICD placement among patients who met LVEF criteria post-MI within a large integrated health care system in the U.S by conducting a retrospective cohort study of Veteran patients hospitalized for AMI from 2004 to 2017 who had documented LVEF ≤35 % from echocardiograms performed between 40 and 455 (90 days +1 year) days post-MI. We used multivariable logistic regression to examine factors associated with ICD placement. Results Of 12,893 patients with LVEF ≤35 % at least 40 days post-MI, 2176 (16.9 %) received an ICD between 91- and 455-days post-MI. Younger age, fewer comorbidities, revascularization with PCI, and greater use of GDMT were associated with increased odds of receiving an ICD. However, half of patients treated with a beta-blocker, ACE inhibitor or angiotensin receptor blocker, and mineralocorticoid receptor antagonist prior to LVEF assessment did not receive an ICD. Eligible Black patients were less likely (odds ratio 0.80, 95 % confidence interval 0.69-0.92) to receive an ICD than White patients. Conclusion Many factors affect ICD placement among Veteran patients with a confirmed LVEF ≤35 % at least 40 days post-MI. Greater understanding of factors influencing ICD placement would help clinicians ensure guideline-concordant care.

Abstract
BACKGROUND Previous studies have documented that Black patients have worse outcomes after lower extremity revascularization procedures compared with White patients. However, the association of race on carotid endarterectomy (CEA) outcomes is not well described. The aim of this study was to compare perioperative outcomes of CEA for Black vs White patients with asymptomatic carotid artery stenosis. STUDY DESIGN All patients who underwent CEA for asymptomatic carotid stenosis in the ACS-NSQIP targeted vascular database (2011-2019) were included. Perioperative (30-day) outcomes were compared for Black vs White patients using multivariable logistic regression adjusting for age/sex, comorbidities, and disease characteristics. RESULTS Of 16,764 asymptomatic CEA patients, 95.2% (N = 15,960) were White and 4.8% (N = 804) were Black. Black patients were slightly younger (mean age 71.4 ± 0.1 vs 69.9 ± 0.3 years, P < 0.001) and more frequently had high-grade carotid artery stenosis compared to White patients (79.5% vs 74.0%, p = 0.001). Comorbidities including hypertension, diabetes, kidney disease, congestive heart failure, and coronary artery disease were all more prevalent among Black patients (p ≤ 0.01). Crude perioperative stroke (2.4% vs 1.3%, p = 0.007) and stroke/death (2.6% vs 1.4%, p = 0.003) were higher for Black patients, but myocardial infarction (1.7% vs 1.5%, p = 0.67) and death (0.4% vs 0.2%, p = 0.12) were similar. After adjusting for baseline differences between groups, the risk of perioperative stroke (odds ratio 1.66, 95% CI 1.01 to 2.73) and stroke/death (odds ratio 1.75, 95% CI 1.10 to 2.81) remained significantly higher for Black patients compared with White patients. CONCLUSIONS Black patients undergoing CEA for asymptomatic carotid artery stenosis had more severe stenosis, more comorbidities, and worse perioperative outcomes compared to White patients. Overall, our data suggest substantial differences in the treatment and outcomes of asymptomatic carotid artery stenosis based on race.

Abstract
The optimal management of patients with asymptomatic carotid stenosis (ACS) is the subject of extensive debate. According to the 2017 European Society for Vascular Surgery guidelines, carotid endarterectomy should (Class IIa; Level of Evidence: B) or carotid artery stenting may be considered (Class IIb; Level of Evidence: B) in the presence of one or more clinical/imaging characteristics that may be associated with an increased risk of late ipsilateral stroke (e.g. silent embolic infarcts on brain computed tomography/magnetic resonance imaging, progression in the severity of ACS, a history of contralateral transient ischemic attack/stroke, microemboli detection on transcranial Doppler, etc.), provided documented perioperative stroke/death rates are <3% and the patient's life expectancy is >5 years. Besides these clinical/imaging characteristics, there are additional individual, ethnic/racial or social factors that should probably be evaluated in the decision process regarding the optimal management of these patients, such as individual patient needs/patient choice, patient compliance with best medical treatment, patient sex, culture, race/ethnicity, age and comorbidities, as well as improvements in imaging/operative techniques/outcomes. The present multispecialty position paper will present the rationale why the management of patients with ACS may need to be individualized.

Abstract
Background and Purpose Despite a higher incidence of stroke and a more adverse cardiovascular risk factor profile in Blacks and Hispanics compared with Whites, carotid artery revascularization is performed less frequently among these subpopulations. We assessed racial differences in high-grade (≥70% diameter-reducing) carotid stenosis. Methods Consecutive clients in a Nationwide Life Line for-Profit Service to screen for vascular disease, 2005 to 2019 were evaluated in a cross-sectional study. The prevalence of high-grade stenosis, defined by a carotid ultrasound peak systolic velocity of ≥230 cm/s, was assessed. Participants self-identified as White, Black, Hispanic, Asian, Native American, or other. Race/ethnic differences were assessed using Poisson regression. The number of individuals in the United States with high-grade stenosis was estimated by applying prevalence estimates to 2015 US Census population estimates. Results The prevalence of high-grade carotid stenosis was estimated in 6 130 481 individuals. The prevalence of high-grade stenosis was higher with increasing age in all race-sex strata. Generally, Blacks and Hispanics had a lower prevalence of high-grade stenosis compared with Whites, while Native Americans had a higher prevalence. For example, for men aged 55 to 65, the relative risk of stenosis compared with Whites was 0.40 (95% CI, 0.29–0.55) and 0.61 (95% CI, 0.46–0.81) for Blacks and Hispanics, respectively; and 1.53 (95% CI, 1.12–2.10) for Native Americans. When these prevalence estimates were applied to the Census estimates of the US population, an estimated 327 721 individuals have high-grade stenosis, of whom 7% are Black, 7% Hispanic, and 43% women. Conclusions Despite their having a more adverse cardiovascular risk profile, there was a lower prevalence of high-grade carotid artery stenosis for both the Black and Hispanic relative to the White clients. This lower prevalence of high-grade stenosis is a potential contributor to the lower use of carotid revascularization procedures in these minority populations.

Atherosclerosis 2020; 292:10-16. [PMID: 31731080 PMCID: PMC6928429 DOI: 10.1016/j.atherosclerosis.2019.10.019] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Revised: 10/12/2019] [Accepted: 10/30/2019] [Indexed: 01/09/2023]
Abstract
BACKGROUND AND AIMS The indications for carotid endarterectomy (CEA) are well established. The aim of the current study was to investigate sex and race-based disparities in the incidence of CEA after adjusting for carotid artery stenosis risk factors. METHODS We conducted a prospective cohort analysis of 14,492 black and white participants in the Atherosclerosis Risk in Communities (ARIC) study without prevalent stroke at baseline (1987-1989). We used Kaplan-Meier curves and Cox proportional hazards models adjusting for sociodemographic, cardiovascular, and disease severity risk factors to quantify the associations of sex and race with incident CEA. RESULTS CEA was performed in 330 of 14,492 ARIC participants during a median of 27 years of follow-up [incidence rate 1.00 (95% CI 0.90-1.12) per 1000 persons-years]. The crude incidence of CEA varied significantly by sex [female vs. male: HR 0.60 (95% CI 0.48-0.74)] and race [black vs. white: HR 0.65 (95% CI 0.49-0.86)]. Adjustment for sociodemographic and cardiovascular risk factors, carotid intima-media thickness, and symptomatic status attenuated the association of sex with CEA [females vs. males HR 0.96 (0.76-1.22)], but black participants had a lower risk of incident CEA after adjustment [HR 0.68 (95% CI 0.49-0.95)]. CONCLUSIONS We found significant variation in the incidence of CEA procedures based on race that was independent of traditional risk factors and carotid IMT. Whether this disparity is a reflection of differences in disease presentation or access to care deserves investigation.

Glob J Health Sci 2015; 8:260-72. [PMID: 26383194 PMCID: PMC4803961 DOI: 10.5539/gjhs.v8n2p260] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2015] [Accepted: 02/26/2015] [Indexed: 11/12/2022] Open
Abstract
Objective: Primary: To examine Veterans Administration (VA) utilization and other potential mediators between racial/ethnic differentials and mortality in veterans diagnosed with traumatic brain injury (TBI). Design: A national cohort of veterans clinically diagnosed with TBI in 2006 was followed from January 1, 2006 through December 31, 2009 or until date of death. Utilization was tracked for 12 months. Differences in survival and potential mediators by race were examined via K-Wallis and chi-square tests. Potential mediation of utilization in the association between mortality and race/ethnicity was studied by fitting Cox models with and without adjustment for demographics and co-morbidities. Poisson regression was used to study the association of race/ethnicity with utilization of specialty services potentially important in the management of TBI. Setting: United States (US) Veterans Administration (VA) Hospitals and Clinics. Participants: 14, 690 US veterans clinically diagnosed with TBI in 2006. Interventions: Not Applicable. The study is a secondary data analysis. Main Outcome Measures: Mortality, Utilization. Results: Hispanic veterans were found to have significantly higher unadjusted mortality (6.69%) than Non-Hispanic White veterans (2.93%). Hispanic veterans relative to Non-Hispanic White were found to have significantly lower utilization of all services examined, except imaging. Neurology was found to be the utilization mediator with the highest percent of excess risk (3.40%) while age was the non utilization confounder with the highest percent of excess risk (31.49%). In fully adjusted models for demographics and co-morbidities, Hispanic veterans relative to Non-Hispanic Whites were found to have less total visits (IRR 0.89), TBI clinic (IRR 0.43), neurology (IRR 0.35), rehabilitation (IRR 0.37), and other visits (IRR 0.85) with only higher mental health visits (IRR 1.53). Conclusions: We found evidence that utilization is a partial mediator between race/ethnicity and mortality, especially neurology utilization. We also found that Hispanic veterans receive significantly less TBI clinic, neurology, rehabilitation and other types of utilization. The use of innovative system factors (decision aids, information tools, patient activation, and adherence support interventions) could be valuable in enhancing utilization of specific TBI related services, especially among ethnic minorities.

Stroke 2015; 46:1525-32. [DOI: 10.1161/strokeaha.115.009013] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2015] [Accepted: 04/06/2015] [Indexed: 01/19/2023]
Abstract
Background and Purpose—
It is not known whether racial or ethnic disparities observed with other revascularization procedures are also seen with carotid artery stenting (CAS) and endarterectomy (CEA).
Methods—
We compared the utilization and outcomes of CAS and CEA across racial/ethnic groups within the CARE Registry between May 2007 and December 2012.
Results—
Between 2007 and 2012, of the 13 129 patients who underwent CAS, majority were non-Hispanic whites (89.3%), followed by blacks (4.4%), Hispanics (4.3%), and other groups (2.0%). A similar distribution was observed among the 10 953 patients undergoing CEA (non-Hispanic whites, 92.6%; blacks, 3.5%; Hispanics, 2.8%; and other groups, 1.1%). During this time period, a trend toward proportionate increase in CAS utilization was observed in non-Hispanic whites and other groups, whereas the opposite was observed among Hispanics and blacks. This trend persisted even when hospitals performing both CAS and CEA were exclusively analyzed. Adherence to antiplatelet and statin therapy was significantly lower among blacks post CEA. In-hospital major adverse cardiac and cerebrovascular events remained comparable across groups post CAS and CEA. At 30 days, the incidence of stroke (7.2%) and major adverse cardiac and cerebrovascular events (8.8%) was higher among blacks post CEA (
P
<0.05), after risk adjustment.
Conclusion—
During the study period, utilization of CAS and CEA was highest among non-Hispanic whites. There was a trend toward increased CAS utilization over time among non-Hispanic whites and other groups, and a trend toward increased CEA utilization among Hispanics and blacks. In-hospital major adverse cardiac and cerebrovascular events remained comparable between groups, whereas 30-day major adverse cardiac and cerebrovascular events were significantly higher in blacks.

Race as a predictor of delay from diagnosis to endarterectomy in clinically significant carotid stenosis. J Vasc Surg 2015; 62:49-56.

Abstract
OBJECTIVE Prompt carotid endarterectomy (CEA) in clinically significant carotid stenosis is important in the prevention of neurologic sequelae. The greatest benefit from surgery is obtained by prompt revascularization on diagnosis. It has been demonstrated that black patients both receive CEA less frequently than white patients do and experience worse postoperative outcomes. We sought to test our hypothesis that black race is an independent risk factor for a prolonged time from sonographic diagnosis of carotid stenosis warranting surgery to the day of operation (TDO). METHODS From 1998 to 2013 at a single institution, 166 CEA patients were retrospectively reviewed using Synthetic Derivative, a de-identified electronic medical record. Factors potentially affecting TDO, including demographics, preoperative cardiac stress testing, degree of stenosis, smoking status, and comorbidities, were noted. Multivariate analysis was performed on variables that trended with prolonged TDO on univariate analysis (P < .10) to determine independent (P < .05) predictors of TDO. Subgroup analyses were further performed on the symptomatic and asymptomatic stenosis cohorts. RESULTS There were 32 black patients and 134 white patients studied; the mean TDO was 78 ± 17 days vs 33 ± 3 days, respectively (P < .001). In addition to the need for preoperative cardiac stress testing, black race was the only variable that demonstrated a trend with (P < .10) or was an independent risk factor for (P < .05) prolonged TDO among all patients (B = 42 days; P < .001) and within the symptomatic (B = 35 days; P = .08) and asymptomatic (B = 35 days; P = .003) cohorts. On Kaplan-Meier analysis, black patients in each stratum of symptomatology (all, symptomatic, and asymptomatic patients) experienced prolonged TDO (log-rank, P < .03 for all three groups). CONCLUSIONS Black race is a risk factor for a temporal delay in CEA for carotid stenosis. Awareness of this disparity may help surgeons avoid undesirable delays in operation for their black patients.

Abstract
Despite a profusion of studies over the past several years documenting racial differences in cancer outcomes, there is a paucity of data as to the root causes underlying these observations. This article reviews work to date focusing on black-white differences in cancer outcomes, explores potential mechanisms underlying these differences, and identifies patient, physician, and health care system factors that may account for persistent racial disparities in cancer care. Research strategies to elucidate the relative influence of these various factors and policy recommendations to reduce persistent disparities are also discussed.

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
PURPOSE Our goal is to describe the effect of race and ethnicity on stroke epidemiology, personal beliefs, access to care, response to treatment, and participation in clinical research. In addition, we seek to determine the state of knowledge on the main factors that may explain disparities in stroke care, with the goal of identifying gaps in knowledge to guide future research. The intended audience includes physicians, nurses, other healthcare professionals, and policy makers. METHODS Members of the writing group were appointed by the American Heart Association Stroke Council Scientific Statement Oversight Committee and represent different areas of expertise in relation to racial-ethnic disparities in stroke care. The writing group reviewed the relevant literature, with an emphasis on reports published since 1972. The statement was approved by the writing group; the statement underwent peer review, then was approved by the American Heart Association Science Advisory and Coordinating Committee. RESULTS There are limitations in the definitions of racial and ethnic categories currently in use. For the purpose of this statement, we used the racial categories defined by the US federal government: white, black or African American, Asian, American Indian/Alaskan Native, and Native Hawaiian/other Pacific Islander. There are 2 ethnic categories: people of Hispanic/Latino origin or not of Hispanic/Latino origin. There are differences in the distribution of the burden of risk factors, stroke incidence and prevalence, and stroke mortality among different racial and ethnic groups. In addition, there are disparities in stroke care between minority groups compared with whites. These disparities include lack of awareness of stroke symptoms and signs and lack of knowledge about the need for urgent treatment and the causal role of risk factors. There are also differences in attitudes, beliefs, and compliance among minorities compared with whites. Differences in socioeconomic status and insurance coverage, mistrust of the healthcare system, the relatively limited number of providers who are members of minority groups, and system limitations may contribute to disparities in access to or quality of care, which in turn might result in different rates of stroke morbidity and mortality. Cultural and language barriers probably also contribute to some of these disparities. Minorities use emergency medical services systems less, are often delayed in arriving at the emergency department, have longer waiting times in the emergency department, and are less likely to receive thrombolysis for acute ischemic stroke. Although unmeasured factors may play a role in these delays, the presence of bias in the delivery of care cannot be excluded. Minorities have equal access to rehabilitation services, although they experience longer stays and have poorer functional status than whites. Minorities are inadequately treated with both primary and secondary stroke prevention strategies compared with whites. Sparse data exist on racial-ethnic disparities in access to surgical care after intracerebral hemorrhage and subarachnoid hemorrhage. Participation of minorities in clinical research is limited. Barriers to participation in clinical research include beliefs, lack of trust, and limited awareness. Race is a contentious topic in biomedical research because race is not proven to be a surrogate for genetic constitution. CONCLUSIONS There are limitations in the current definitions of race and ethnicity. Nevertheless, racial and ethnic disparities in stroke exist and include differences in the biological determinants of disease and disparities throughout the continuum of care, including access to and quality of care. Access to and participation in research is also limited among minority groups. Acknowledging the presence of disparities and understanding the factors that contribute to them are necessary first steps. More research is required to understand these differences and find solutions.

Abstract
BACKGROUND Previous studies show that black patients undergo carotid endarterectomy (CEA) less frequently than white patients. Diagnostic imaging is necessary to determine whether a patient is a candidate for the operation. We determined whether there were differences in the use of diagnostic carotid imaging and the frequency of CEA between elderly black and white ischemic stroke patients. METHODS Medicare fee-for-service beneficiaries with discharge diagnoses of ischemic stroke (International Classification of Diseases, 9th revision codes 433, 434, and 436) were randomly selected for inclusion in the National Stroke Project 1998-1999, 2000-2001. Receipt of at least one type of carotid imaging study was compared for black and white patients. Binomial logistic regression models were used to evaluate the associations between race and receipt of carotid imaging and CEA with adjustment for demographics, degree of carotid artery stenosis, and other clinical covariates. RESULTS Among 19,639 stroke patients (1974 black, 17,655 white), 69.6% received at least 1 diagnostic carotid imaging test (blacks 68.4%; whites 69.7%; P = .233). After risk adjustment, blacks were less likely to receive carotid imaging (adjusted odds ratio [OR] 0.87; 95% confidence interval [CI] 0.78-0.97). There was no relationship between race and the receipt of CEA after adjustment for degree of carotid stenosis and other covariates (adjusted OR 1.14; 95% CI 0.66-1.96). CONCLUSIONS Black ischemic stroke patients were less likely to receive diagnostic carotid imaging than white patients, although the difference was small and only significant after risk adjustment. There was no difference in the proportion having CEA after adjustment for degree of carotid artery stenosis and other clinical factors.

Abstract
OBJECTIVE This study examines two dimensions of racial segregation across hospitals, using a disease for which substantial disparities have been documented. DATA SOURCES Black (n=32,289) and white (n=244,042) patients 67 years and older admitted for acute myocardial infarction during 2004-2005 in 105 hospital markets were identified from Medicare data. Two measures of segregation were calculated: Dissimilarity (i.e., dissimilar distribution by race across hospitals), and Isolation (i.e., racial isolation within hospitals). For each measure, markets were categorized as having low, medium, or high segregation. STUDY DESIGN The relationship of hospital segregation to residential segregation and other market characteristics was evaluated. Cox proportional hazards regression was used to evaluate disparities in the use of revascularization within 90 days by segregation level. RESULTS Agreement of segregation category based on Dissimilarity and Isolation was poor (kappa=0.12), and the relationship of disparities in revascularization to segregation differed by measure. The hazard of revascularization for black relative to white patients was lowest (i.e., greatest disparity) in markets with low Dissimilarity, but it was unrelated to Isolation. CONCLUSIONS Significant racial segregation across hospitals exists in many U.S. markets, although the magnitude and relationship to disparities depends on definition. Dissimilar distribution of race across hospitals may reflect divergent cultural preferences, social norms, and patient assessments of provider cultural competence, which ultimately impact utilization.

Abstract
Objective.Ethnic disparities in the use of total joint arthroplasty (TJA) may be attributed to differences in the clinical appropriateness to undergo TJA. We sought to determine if racial differences in clinical appropriateness for surgery existed among a sample of primary care clinic patients with moderately to severely symptomatic knee or hip osteoarthritis (OA).Methods.We used the cross-sectional data of 684 patients who are potential candidates for TJA. Using a validated TJA appropriateness algorithm, an appropriateness factor was derived using the following variables: age (50–70 or > 70 yrs), Charlson comorbidity (≤ 1 or > 1), Western Ontario and McMaster Universities OA Index (WOMAC) pain and physical function, and adequacy of previous medical management. We used logistic regression to estimate the association of race with the dichotomous outcome of clinical appropriateness for TJA consideration.Results.Sample consisted of 425 (62%) whites and 260 (38%) African Americans; 532 (78%) had knee OA and 153 (22%) had hip OA. The mean age was 64 ± 9 years and the mean body mass index was 33.6 ± 8 kg/m2. The mean overall WOMAC score was 56 ± 14 (range 30–96), suggesting moderately severe OA. There were no significant racial group differences (p = 0.3) in the proportions of those deemed clinically appropriate for TJA. After controlling for potential confounders, race was not a predictor of clinical appropriateness for TJA (odds ratio 1.2, 95% confidence interval 0.8–1.8, p = 0.3).Conclusion.African Americans and whites were equally appropriate to be considered for TJA.

Abstract
BACKGROUND AND PURPOSE Prior work documented racial and ethnic disparities in incidence of stroke, stroke risk factors, and use of carotid endarterectomy. Less is known about disparities in outcomes and appropriateness of carotid endarterectomy or reasons for such inequalities. METHODS This was a population-based cohort of carotid endarterectomy performed in Medicare beneficiaries in New York. Clinical data were abstracted from medical charts to assess sociodemographics, clinical indication for carotid endarterectomy, disease severity, comorbidities, and deaths and strokes within 30 days of surgery. Appropriateness was based on validated criteria from a national expert panel. Differences in patients, providers, outcomes, and appropriateness were compared using chi(2) tests. Differences in risk-adjusted rates of death or nonfatal stroke were compared using multiple logistic regression accounting for patient, physician, and hospital-level risk factors. RESULTS Overall, 95.3% of patients undergoing carotid endarterectomy were white, 2.5% black, and 2.2% Hispanic (N=9093). Minorities had more severe neurological disease and more comorbidities and were more likely to be cared for by lower-volume surgeons and hospitals (P<0.0001). Rates of 30-day death/stroke were higher in Hispanics (9.5%) and blacks (6.9%) than whites (3.8%; P<0.0001). Multivariable analyses that adjusted for presurgical patient risk and provider characteristics found that blacks no longer had significantly worse outcomes (OR=1.37; CI, 0.78 to 2.40), although the higher risk of death/stroke in Hispanics persisted (OR=1.87; CI, 1.09 to 3.19). Minorities had higher rates of inappropriate surgery (Hispanics 17.6%, black 13.0%, white 7.9%; P<0.0001) largely due to higher comorbidity. CONCLUSIONS Minorities had worse outcomes and higher rates of inappropriate surgery. Differences in underlying presurgical risk factors and provider characteristics explained the higher risk of complications in blacks, but not Hispanics.

Abstract
OBJECTIVE To evaluate the patterns of care in elderly glioblastoma (GBM) patients from a large population-based registry. METHODS We identified a cohort of GBM patients 65 years or older from Surveillance, Epidemiology, and End Results cancer registry data linked with Medicare claims between 1994 and 2002. We assessed the impact of demographic characteristics and comorbidities on the probability of undergoing surgical resection, radiotherapy (RT), and chemotherapy within 3 months of diagnosis using multivariate logistic regression. RESULTS A total of 4,137 patients with GBM were included, with a median overall survival of 4 months. Sixty-one percent of patients underwent resection at diagnosis; 65% received RT and 10% received chemotherapy within 3 months of diagnosis. In a multivariate regression analysis, age was the most significant predictor of resection, RT, or chemotherapy. Black race (odds ratio [OR], 0.64; p = 0.008) was associated with lower rates of surgical resection. Factors associated with decreased likelihood of receiving RT included unmarried marital status (OR, 0.64; p < 0.0001) and more comorbidities (OR, 0.55; p < 0.0001). Factors associated with decreased likelihood of receiving chemotherapy included unmarried marital status (OR, 0.59; p = 0.0002) and more comorbidities (OR, 0.56; p = 0.02). INTERPRETATION Survival of elderly GBM patients was poor in this population-based study. Age, marital status, and comorbidities influenced the probability of receiving RT or chemotherapy in this cohort.

Abstract
OBJECTIVES To better understand the causes of racial disparities in health care, we reviewed and synthesized existing evidence related to disparities in the "equal access" Veterans Affairs (VA) health care system. METHODS We systematically reviewed and synthesized evidence from studies comparing health care utilization and quality by race within the VA. RESULTS Racial disparities in the VA exist across a wide range of clinical areas and service types. Disparities appear most prevalent for medication adherence and surgery and other invasive procedures, processes that are likely to be affected by the quantity and quality of patient-provider communication, shared decision making, and patient participation. Studies indicate a variety of likely root causes of disparities including: racial differences in patients' medical knowledge and information sources, trust and skepticism, levels of participation in health care interactions and decisions, and social support and resources; clinician judgment/bias; the racial/cultural milieu of health care settings; and differences in the quality of care at facilities attended by different racial groups. CONCLUSIONS Existing evidence from the VA indicates several promising targets for interventions to reduce racial disparities in the quality of health care.

Abstract
BACKGROUND This longitudinal, qualitative study explores barriers to postpartum sterilization from the perspective of low-income minority women. We examine women's feelings and attitudes regarding a canceled or postponed procedure over time. STUDY DESIGN We conducted structured, in-depth baseline interviews with 34 postpartum women with unfulfilled sterilization requests in a university hospital setting. Follow-up phone interviews were conducted at 6 weeks and 6 months postpartum. RESULTS Reasons for unfulfilled sterilization requests included last-minute misgivings, maternal medical complications, lack of a valid Medicaid consent form, fear of the procedure and provider influence. Sense of autonomy regarding sterilization decision making and ability to obtain interval sterilization or initiate and/or successfully use reversible contraception influenced subsequent attitudes regarding an unfulfilled request. CONCLUSIONS Sterilization counseling should include comprehensive information regarding the surgical procedure and associated risks and the development of a backup contraceptive plan, with particular emphasis on increasing contraceptive self-efficacy and autonomy in sterilization decision making.

Abstract
PURPOSE Black patients with renal cell cancer have shorter survival compared with their white counterparts, but the causes for this disparity are unclear. To elucidate reasons for this inequality, we examined differences in treatment and survival between black and white patients. PATIENTS AND METHODS A retrospective cohort study was conducted using data from the linked Surveillance, Epidemiology and End Results (SEER) cancer registry and Medicare databases. Participants included 964 black and 10,482 white patients age >or= 65 years who were enrolled into Medicare and diagnosed with renal cell cancer between 1986 and 1999. Information on surgical treatment was ascertained from both databases, whereas data regarding coexisting illness and survival was obtained from the Medicare database. RESULTS The percentage of black patients receiving nephrectomy treatment was significantly lower compared with whites (61.2% v 70.4%; P < .0001). After adjustment for age, sex, median income, cancer stage, tumor size, and comorbidity index, blacks were less likely to undergo nephrectomy treatment compared with whites (risk ratio = 0.93; 95% CI, 0.90 to 0.96). Overall survival was worse for blacks than whites even after adjustment for demographic and cancer prognostic factors (hazard ratio [HR] = 1.16; 95% CI, 1.07 to 1.25); however, additional adjustment for comorbidity index and nephrectomy treatment reduced the disparity substantially (HR = 1.00; 95% CI, 0.93 to 1.09). CONCLUSION This study indicates that the lower survival rate among blacks compared with whites with renal cell cancer can be explained largely by the increased number of comorbid health conditions and the lower rate of surgical treatment among black patients.

Abstract
BACKGROUND Warfarin has been shown to decrease the rate of thromboembolic events in patients with nonvalvular atrial fibrillation, but it is frequently underprescribed. Our goal was to establish whether there have been racial disparities in the filling of warfarin prescriptions for patients with newly incident nonvalvular atrial fibrillation. METHODS We conducted a retrospective analysis of Ohio Medicaid claims between January 1, 1997 and May 31, 2002, for recipients with newly incident nonvalvular atrial fibrillation. Race was identified from the demographic information in the database, and the analysis was limited to white and African-American patients. The main outcome measure was the filling of a prescription for warfarin at any time between 7 days prior to the initial diagnosis of atrial fibrillation and 30 days after the initial diagnosis. To evaluate the independent role of race in the filling of warfarin prescriptions, we created a multivariable logistic regression model incorporating predictors significant at P < 0.10 in the univariate model. RESULTS A total of 6283 patients were identified as having newly incident nonvalvular atrial fibrillation, 18.5% of whom were African-American. In general, African-American patients had a higher rate of comorbid illness. Warfarin prescriptions were filled for 9.4% of white patients and 7.6% of African-American patients. When controlling for significant confounders in the multivariable logistic regression model, African-American patients had an adjusted odds ratio for receiving warfarin of 0.76 (95% CI, 0.60-0.98) when compared with white patients. CONCLUSION African-American patients in the Ohio Medicaid population between 1998 and 2002 were significantly less likely than white patients to fill a warfarin prescription for newly incident nonvalvular atrial fibrillation.

Abstract
Achieving cultural competence in the care of a patient who is a member of an ethnic or racial minority is a multifaceted project involving specific cultural knowledge as well as more general skills and attitude adjustments to advance cross-cultural communication in the clinical encounter. Using the important example of the African American patient, the authors examine relevant historical and cultural information as it relates to providing culturally competent health care. The authors identify key influences, including the legacy of slavery, Jim Crow discrimination, the Tuskegee syphilis study, religion's interaction with health care, the use of home remedies, distrust, racial concordance and discordance, and health literacy. The authors propose that the awareness of specific information pertaining to ethnicity and race enhances cross-cultural communication and ways to improve the cultural competence of physicians and other health care providers by providing a historical and social context for illness in another culture. Cultural education, modular in nature, can be geared to the specific populations served by groups of physicians and provider organizations. Educational methods should include both information about relevant social group history as well as some experiential component to emotively communicate particular cultural needs. The authors describe particular techniques that help bridge the cross-cultural clinical communication gaps that are created by patients' mistrust, lack of cultural understanding, differing paradigms for illness, and health illiteracy.

Abstract
OBJECTIVE This study assessed the relative importance of clinical and nonclinical factors in a provider's decision to recommend carotid endarterectomy (CEA) for a patient, with emphasis on the role of the patient's race in the provider's assessment of the risks and benefits of the procedure. METHODS The study was a secondary analysis of data on the use of CEA conducted in a patient sample of 355 white and black patients who were referred for evaluation for CEA and were adjudicated preoperatively as appropriate candidates for the procedure by objective criteria. The patients were from five VA medical centers nationally. The primary outcome was the provider's recommendation that the patient receive CEA. Patient factors included age, race, the degree of carotid artery stenosis, clinical status, trust in the provider, and aversion to surgery. Provider factors were assessment of the patient's risks and benefits from CEA, including perceived efficacy of the surgery, perceived risk of stroke < or =1 year without the surgery, and perceived risk of stroke < or =30 days from the surgery. RESULTS The primary factor associated with a provider's decision to recommend CEA was his or her assessment of the patient's risk of stroke without the surgery. The patient's race was not associated with the provider's assessments of the patient's risks or benefits from CEA. CONCLUSION A major determinant of a provider's recommendation for a patient to receive CEA endarterectomy is the assessment of the patient's likely future risk of stroke, regardless of the patient's race.

Abstract
PURPOSE Preferences are known to vary by individuals' personal experience with a health state, but variation among respondents' scoring of the same hypothetical state is unproven but relevant to the use of community-perspective preference scores. This research explored the systematic contribution of respondents' age, race and gender to variability in community perspective preferences for hypothetical health states. METHODS Data from four community samples were pooled for the analysis. Linear regression modeling was used to test for the effect of respondent age, race and gender on preference scores while controlling for health state severity. RESULTS In this sample of 956 preference scores from 390 individuals across 4 studies, older respondents provided lower preference scores for the same hypothetical health state compared with younger respondents (regression coefficient for 1 year of age = -0.002, p < 0.001), and white individuals provided higher preference scores for the same states compared with non-white individuals (regression coefficient = 0.056, p = 0.014). CONCLUSION Preferences for hypothetical health states may vary by the age and race of the respondent providing the score. Community-perspective preferences should thus be elicited from large, random samples of the relevant population to ensure variation on these as well as other yet-unidentified characteristics that may affect scores.

Abstract
Black Americans bear a disproportionate stroke burden in the United States compared with other racial and ethnic groups. Poor stroke awareness, higher vascular risk factor burden, limited access to care, mistrust of the medical system, and inequities in diagnostic testing and treatment usage may account for some of the disparity. In addition, blacks have historically been under-represented in observational studies and clinical trials of stroke prevention and treatment. Therefore, our knowledge regarding stroke in black Americans is somewhat limited. This article provides an update on developments in our understanding regarding stroke in this at-risk population.

Abstract
OBJECTIVE To determine whether race is associated with outcomes of inpatient stroke rehabilitation. DESIGN Retrospective cohort study. SETTING A community-based inpatient rehabilitation facility. PARTICIPANTS Poststroke patients (N=1002) admitted to a community-based inpatient rehabilitation facility between 1995 and 2001. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Functional improvement at discharge from the rehabilitation facility, discharge disposition, and functional improvement at 3 months after discharge. Inpatient and follow-up data were collected from the facility's electronic patient database. We used the FIM instrument to assess functional status at admission, discharge, and follow-up. RESULTS In multivariable models, blacks achieved less functional improvement at discharge (-1.9 FIM points, P=.02) compared with whites and, despite worse FIM scores, were more likely to be discharged to home (adjusted odds ratio=1.7; 95% confidence interval, 1.1-2.5). Although Asian-American patients did not differ from whites in terms of functional improvement at discharge or disposition, they had less improvement at 3 months following discharge (-6.3 FIM points, P=.005). CONCLUSIONS We identified racial disparities in poststroke outcomes in a community-based inpatient rehabilitation facility. Future research in stroke rehabilitation should explore the consistency of these findings across settings and if they are confirmed, identify explanatory mediators to better inform efforts to eliminate racial disparities.

Abstract
BACKGROUND Access to health care varies according to a person's race and ethnicity. Delaying treatment is one measure of access with important health consequences. OBJECTIVE Determine whether perceptions of unfair treatment because of race or ethnicity are associated with reported treatment delays, controlling for economic constraints, self-reported health, depression, and demographics. DESIGN Cross-sectional, observational study. PARTICIPANTS A randomly selected community sample of 181 blacks, 148 Latinos, and 193 whites in Durham County, NC. MEASUREMENTS A phone survey conducted in 2002 to assess discrimination, trust in medical care, quality of care, and access to care. Treatment delays were measured by whether or not a person reported delaying or forgoing filling a prescription and delaying or forgoing having a medical test/treatment in the past 12 months. Perceived discrimination was measured as unfair treatment in health care and as racism in local health care institutions. RESULTS The odds of delaying filling prescriptions were significantly higher (odds ratio (OR)=2.02) for persons who perceived unfair treatment, whereas the odds of delaying tests or treatments were significantly higher (OR=2.42) for persons who thought racism was a problem in health care locally. People with self-reported depression and people who reported not working had greater odds of delaying both types of care. CONCLUSIONS A prospective cohort study with both personal and macro measures of discrimination, as well as more refined measures of treatment delays, would help us better understand the relationship between perceived discrimination and treatment delays.

Abstract
PURPOSE Few studies have attempted to link patients' beliefs about racism in the health care system with how they use and experience health care. METHODS Using telephone survey data from a national sample of 1,479 whites, 1,189 African Americans, and 983 Latinos, we explored patients' beliefs about racism, their preferences for the race and ethnicity of their physician, and their satisfaction with that physician. A scale was developed to reflect patients' beliefs about racism. Race-stratified analyses assessed associations between patients' beliefs, racial preferences for physicians, choice of physician, and satisfaction with care. RESULTS Among African Americans, stronger beliefs about racial discrimination in health care were associated with preferring an African American physician (P <.001). Whereas only 22% of African Americans preferred an African American physician, those who preferred a African American physician and had an African American physician were more likely to rate their physician as excellent than did African Americans who preferred a African American physician but had a non-African American physician (57% vs 20%, P <.001). Latinos with stronger beliefs about discrimination in health care were more likely to prefer a Latino physician (P <.001). One third of Latinos preferred a Latino physician. Though not statistically significant, those who preferred and had a Latino physician rated their physician higher than Latinos who preferred a Latino physician but had a non-Latino physician (40% vs 29%). CONCLUSIONS Many African Americans and Latinos perceive racism in the health care system, and those who do are more likely to prefer a physician of their own race or ethnicity. African Americans who have preferences are more often satisfied with their care when their own physicians match their preferences.

Abstract
RATIONALE Important variations exist in the treatment of non-small cell lung cancer. Because resection is the most effective treatment for patients with early disease, disparities in surgical rates can generate considerable differences in outcomes. OBJECTIVE We analyzed data from a national population-based registry to evaluate disparities in the treatment of Hispanic and white patients with stage I lung cancer and to assess the extent to which these inequalities explain survival differences. METHODS This study included 16,036 Hispanic and white patients with stage I lung cancer diagnosed between 1991 and 2000. Cases were identified from the Surveillance, Epidemiology, and End Results registry. Survival was compared among white and Hispanics using Kaplan-Meier curves. Stratified survival curves and Cox regression were used to evaluate whether inequalities in stage (IA vs. IB) and resection could explain survival differences. RESULTS Hispanics had worse overall and lung cancer-specific survival compared with whites (p = 0.04 and 0.008, respectively). Five-year lung cancer survival was 54% for Hispanics versus 62% for whites. Hispanics were more frequently diagnosed with stage IB disease (p = 0.0002) and less likely to undergo resection (p = 0.03). Among resected patients, survival was similar for the two groups, as it was among those who did not undergo unresection. After adjusting for surgery and stage, there was no difference in survival between groups. CONCLUSIONS Hispanics with stage I lung cancer had worse survival as compared with whites. These disparities are largely explained by lower rates of resection and higher probability of diagnosis at stage IB. Future work must delineate why Hispanics are receiving less surgery.

Abstract
Patients express risk aversion toward surgery, particularly if surgery can lead to lifelong debility and loss of independence. When faced with a guarantee of progressive lung cancer and no alternatives for cure, however, patients are willing to take extremely high risks of postoperative complications and surgery-related death. This result occurs because risk aversion toward unrelenting cancer death supersedes patients' risk attitudes toward almost all other health states. By adding conditions such as misunderstanding of prognosis, diagnostic uncertainty, a patient's denial of diagnosis, an actual alternative cure such as radiation therapy, or a perceived alternative cure such as prayer, decisions can be shifted so that risk aversion to surgery can predominate. In practical terms, the following statements can be made: 1. For patients who surely have operable stage I or stage II non small cell lung cancer, if patient risk preferences are taken seriously, the pulmonary function level and comorbidities that are acceptable for the offer of surgical care probably need to be liberalized. Patients with short life expectancies because of advanced age or comorbid illness and patients with severe preoperative functional debility (eg, bed-to-chair limitation as defined earlier) should not be candidates, however. 2. The diagnosis of cancer needs to be confirmed absolutely as often as possible before lung resection surgery. 3. Physicians or a staff member must communicate prognosis to a patient as precisely and numerically as possible and ensure the patient's understanding of the data presented. 4. This communicator also must explore a patient's trust in the diagnosis and probe for beliefs in alternative solutions. Important areas for future study include the search for methods that most accurately communicate risk information to patients, especially patients with low numeracy skills. Part of this communication effort should involve the exploration and discussion of patients' alternative beliefs and ways of using these belief systems to help them make the best possible decisions for their long-term health and quality of life. Also, clinicians must identify pulmonary and other predictors of mortality rates and the debility states that patients' cite as most important according to their risk preferences and give up the predictors of transient postoperative complications that patients find acceptable.

Abstract
BACKGROUND AND PURPOSE Patient risk perception for surgery may be central to their willingness to undergo surgery. This study examined potential factors associated with patient aversion of surgery. METHODS This is a secondary data analysis of a prospective cohort study that examined patients referred for evaluation of carotid artery stenosis at five Veterans Affairs Medical Centers. The study collected demographic, clinical, and psychosocial information related to surgery. This analysis focused on patient response to a question assessing their aversion to surgery. RESULTS Among the 1065 individuals, at the time of evaluation for carotid endarterectomy (CEA), 66% of patients had no symptoms, 16% had a transient ischemic attack, and 18% had stroke. Twelve percent of patients referred for CEA evaluation were averse to surgery. In adjusted analyses, increased age, black race, no previous surgery, lower level of chance locus of control, less trust of physicians, and less social support were significantly related to greater likelihood of surgery aversion among individuals referred for CEA evaluation. Patient degree of medical comorbidity and a validated measure of preoperative risk score were not associated with increased aversion to surgery. CONCLUSIONS In previous work, aversion to CEA was associated with lack of receipt of CEA even after accounting for patient clinical appropriateness for surgery. We identified important patient characteristics associated with aversion to CEA. Interventions designed to assist patient decision making should focus on these more complex factors related to CEA aversion rather than the simple explanation of clinical usefulness.

Abstract
PURPOSE Multiple studies have examined predictors of seizure outcomes after epilepsy surgery. Most are single-center series with limited sample size. Little information is available about the selection process for surgery and, in particular, the proportion of patients who ultimately have surgery and the characteristics that identify those who do versus those who do not. Such information is necessary for providing the epidemiologic and clinical context in which epilepsy surgery is currently performed in the United States and in other developed countries. METHODS An observational cohort of 565 surgical candidates was prospectively recruited from June 1996 through January 2001 at six Northeastern and one Midwestern surgical centers. Standardized eligibility criteria and protocol for presurgical evaluations were used at all seven sites. RESULTS Three hundred ninety-six (70%) study subjects had resective surgery. Clinical factors such as a well-localized magnetic resonance imaging (MRI) abnormality and consistently localized EEG findings were most strongly associated with having surgery. Of those who underwent intracranial monitoring (189, 34%), 85% went on to have surgery. Race/ethnicity and marital status were marginally associated with having surgery. Age, education, and employment status were not. Demographic factors had little influence over the surgical decision. More than half of the patients had intractable epilepsy for >/=10 years and five or more drugs had failed by the time they initiated their surgical evaluation. During the recruitment period, eight new antiepileptic drugs were approved by the Food and Drug Administration for use in the United States and came into increasing use in this study's surgical candidates. Despite the increased availability of new therapeutic options, the proportion that had surgery each year did not fluctuate significantly from year to year. This suggests that, in this group of patients, the new drugs did not provide a substantial therapeutic benefit. CONCLUSIONS Up to 30% of patients who undergo presurgical evaluations for resective epilepsy surgery ultimately do not have this form of surgery. This is a group whose needs are not currently met by available therapies and procedures. Lack of clear localizing evidence appears to be the main reason for not having surgery. To the extent that these data can address the question, they suggest that repeated attempts to control intractable epilepsy with new drugs will not result in sustained seizure control, and eligible patients will proceed to surgery eventually. This is consistent with recent arguments to consider surgery earlier rather than later in the course of epilepsy. Postsurgical follow-up of this group will permit a detailed analysis of presurgical factors that predict the best and worst seizure outcomes.

Abstract
OBJECTIVE The purpose of this study was to identify clinical and nonclinical factors associated with failure to perform carotid endarterectomy (CEA) in patients with clinically appropriate indications. We analyzed data from a prospective cohort study performed at five Veterans Affairs medical centers. Patients were referred for carotid artery evaluation if they had at least 50% stenosis in one carotid artery, had no history of CEA, and were independently classified preoperatively as appropriate candidates for CEA, according to clinical criteria. The primary outcome was receipt of CEA within 6 months of evaluation. Data were collected by medical record review and interview regarding clinical status, and patient and physician perception of the risks and benefits of CEA. RESULTS Among clinically appropriate candidates for CEA, 66.8% (n = 233) did not undergo the operation. Compared with patients who did undergo CEA, a greater proportion of these patients had no symptoms (68.7% vs 45.7%; P <.001). A twofold greater proportion of patients who did not undergo CEA were in the highest quartile of reported aversion to surgery. Moreover, a fourfold greater proportion were perceived by their physicians to be at less than 5% risk for future stroke without the operation, and more than a twofold greater proportion were believed to experience less than 5% efficacy from the operation by their providers (P <.01). In multivariable analyses, four characteristics were significantly associated with whether an appropriate candidate did not receive CEA: asymptomatic disease, less than 70% stenosis, high expressed aversion to surgery score, and low (<5%) provider-perceived efficacy of the operation. CONCLUSION Among patients in the Veterans Affairs health care system who are clinically appropriate candidates for CEA, those who did not receive the operation were less likely to have symptomatic disease or high-grade carotid artery stenosis, but were more likely to report high aversion to surgery and to have a provider who believed CEA would not be efficacious.
