Racial disparities in medical care

Trends in "Deaths of Despair" Among Working-Aged White and Black Americans, 1990-2017

Life expectancy for US White men and women declined between 2013 and 2017. Initial explanations for the decline focused on increases in "deaths of despair" (i.e., deaths from suicide, drug use, and alcohol use), which have been interpreted as a cohort-based phenomenon afflicting middle-aged White Americans. There has been less attention on Black mortality trends from these same causes, and whether the trends are similar or different by cohort and period. We complement existing research and contend that recent mortality trends in both the US Black and White populations most likely reflect period-based exposures to 1) the US opioid epidemic and 2) the Great Recession. We analyzed cause-specific mortality trends in the United States for deaths from suicide, drug use, and alcohol use among non-Hispanic Black and non-Hispanic White Americans, aged 20-64 years, over 1990-2017. We employed sex-, race-, and cause-of-death-stratified Poisson rate models and age-period-cohort models to compare mortality trends. Results indicate that rising "deaths of despair" for both Black and White Americans are overwhelmingly driven by period-based increases in drug-related deaths since the late 1990s. Further, deaths related to alcohol use and suicide among both White and Black Americans changed during the Great Recession, despite some racial differences across cohorts.

COVID-19 mortality among kidney transplant candidates is strongly associated with social determinants of health

The COVID-19 pandemic has affected all portions of the global population. However, many factors have been shown to be particularly associated with COVID-19 mortality including demographic characteristics, behavior, comorbidities, and social conditions. Kidney transplant candidates may be particularly vulnerable to COVID-19 as many are dialysis-dependent and have comorbid conditions. We examined factors associated with COVID-19 mortality among kidney transplant candidates from the National Scientific Registry of Transplant Recipients from March 1 to December 1, 2020. We evaluated crude rates and multivariable incident rate ratios (IRR) of COVID-19 mortality. There were 131 659 candidates during the study period with 3534 all-cause deaths and 384 denoted a COVID-19 cause (5.00/1000 person years). Factors associated with increased COVID-19 mortality included increased age, males, higher body mass index, and diabetes. In addition, Blacks (IRR = 1.96, 95% C.I.: 1.43-2.69) and Hispanics (IRR = 3.38, 95% C.I.: 2.46-4.66) had higher COVID-19 mortality relative to Whites. Patients with lower educational attainment, high school or less (IRR = 1.93, 95% C.I.: 1.19-3.12, relative to post-graduate), Medicaid insurance (IRR = 1.73, 95% C.I.: 1.26-2.39, relative to private), residence in most distressed neighborhoods (fifth quintile IRR = 1.93, 95% C.I.: 1.28-2.90, relative to first quintile), and most urban and most rural had higher adjusted rates of COVID-19 mortality. Among kidney transplant candidates in the United States, social determinants of health in addition to demographic and clinical factors are significantly associated with COVID-19 mortality.

Improving Cultural Knowledge to Facilitate Cultural Adaptation of Pain Management in a Culturally and Linguistically Diverse Community

Purpose: Health care disparities exist for people from culturally and linguistically diverse (CALD) communities. Addressing the cultural competence of health care providers could limit these disparities. The aim of this study was to improve cultural knowledge of and humility regarding pain in a CALD community. Method: This interpretive description qualitative study used focus group discussions (FGDs) to generate ideas about how South Asian culture could influence how health care providers manage pain. A total of 14 people with pain and of South Asian background (6 women and 8 men, aged 28–70 y) participated. Two investigators independently analyzed the data. This process involved repeatedly reading the transcripts, then manually sorting the key messages into categories. The investigators compared their categorizations and resolved differences through discussion. Next, similar categories and concepts were grouped into ideas (potential themes). These ideas, along with supporting categories and verbatim quotes, were presented to the full research team for feedback. After compiling the feedback, the ideas formed the thematic representation of the data. Results: The data from the FGDs revealed how pain management could be culturally adapted. The FGDs generated four themes about South Asian cultural perspectives that could influence the pain management experience for people living with pain: (1) cultural and linguistic impediments to communication, (2) understanding of pain in terms of the extent to which it interferes with function and work, (3) nurturing or personal attention as a marker of good care, and (4) value attributed to traditional ideas of illness and treatment. Conclusion: This study demonstrates how engaging with CALD people living with pain can lead to improved cultural knowledge and humility that can form the basis for adapting pain management. Through this process, it is more likely that a meaningful and client-centred pain management plan can be developed.

Assessment of Racial Disparities in Primary Care Physician Specialty Referrals

IMPORTANCE

Disparities in quality of care according to patient race and socioeconomic status persist in the US. Differential referral patterns to specialist physicians might be associated with observed disparities.

OBJECTIVE

To examine whether differences exist between Black and White Medicare beneficiaries in the observed patterns of patient sharing between primary care physicians (PCPs) and physicians in the 6 specialties to which patients were most frequently referred.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional observational study of Black and White Medicare beneficiaries used claims data from 2009 to 2010 on 100% of traditional Medicare beneficiaries who were seen by PCPs and selected high-volume specialists in 12 health care markets with at least 10% of the population being Black. Statistical analyses were conducted from December 20, 2017, to September 30, 2020.

EXPOSURES

Differences in patterns of patient sharing among Black and White patients.

MAIN OUTCOMES AND MEASURES

Primary care physician and specialist degree (the number of other PCPs or specialists to whom each physician is connected) and strength (the number of shared patients per connection, overall, for Black patients and White patients and after equalizing the numbers of Black and White patients per PCP), as well as distance between PCP and patient and specialist zip code centroids.

RESULTS

The 12 selected markets ranged in size from Manhattan, New York (187 054 Black or White beneficiaries seen by at least 2 physicians within an episode of care; 9794 total physicians), to Tallahassee, Florida (44 644 Black or White beneficiaries seen by at least 2 physicians within an episode of care; 847 total physicians). The percentage of Black beneficiaries ranged from 11.5% (Huntsville, Alabama) to 46.8% (Chicago, Illinois). The mean PCP-specialist degree (number of specialists with whom a PCP shares patients) was lower for Black patients than for White patients. For instance, the mean PCP-cardiologist degree across all markets for White patients was 17.5 compared with 8.8 for Black patients. After sampling White patients to equalize the numbers of patients seen, the degree differences narrowed but were still not equivalent in many markets (eg, for all specialties in Baton Rouge, Louisiana: 4.5 for Black patients vs 5.7 for White patients). Specialist networks among White patients were much larger than those constructed based just on Black patients (eg, for cardiology across all markets: 135 for Black patients vs 330 for White patients), even after equalizing the numbers of patients seen per PCP (123 for Black patients vs 211 for White patients). The overall test for differences in referral patterns was statistically significant for all 6 specialties examined in 7 of the 12 markets and in 5 specialties for another 3.

CONCLUSIONS AND RELEVANCE

This study suggests that differences exist in specialist referral patterns by race among Medicare beneficiaries. This is an observational study, and thus some differences might have resulted from patient-initiated visits to specialists.

Autoimmune encephalitis epidemiology and a comparison to infectious encephalitis

OBJECTIVE

To evaluate the incidence and prevalence of autoimmune encephalitis and compare it to that of infectious encephalitis.

METHODS

We performed a population-based comparative study of the incidence and prevalence of autoimmune and infectious encephalitis in Olmsted County, Minnesota. Autoimmune encephalitis diagnosis and subgroups were defined by 2016 diagnostic criteria, and infectious encephalitis diagnosis required a confirmed infectious pathogen. Age- and sex-adjusted prevalence and incidence rates were calculated. Patients with encephalitis of uncertain etiology were excluded.

RESULTS

The prevalence of autoimmune encephalitis on January 1, 2014 of 13.7/100,000 was not significantly different from that of all infectious encephalitides (11.6/100,000; p = 0.63) or the viral subcategory (8.3/100,000; p = 0.17). The incidence rates (1995-2015) of autoimmune and infectious encephalitis were 0.8/100,000 and 1.0/100,000 person-years, respectively (p = 0.58). The number of relapses or recurrent hospitalizations was higher for autoimmune than infectious encephalitis (p = 0.03). The incidence of autoimmune encephalitis increased over time from 0.4/100,000 person-years (1995-2005) to 1.2/100,000 person-years (2006-2015; p = 0.02), attributable to increased detection of autoantibody-positive cases. The incidence (2.8 vs 0.7/100,000 person-years, p = 0.01) and prevalence (38.3 vs 13.7/100,000, p = 0.04) of autoimmune encephalitis was higher among African Americans than Caucasians. The prevalence of specific neural autoantibodies was as follows: myelin oligodendrocyte glycoprotein, 1.9/100,000; glutamic acid decarboxylase 65, 1.9/100,000; unclassified neural autoantibody, 1.4/100,000; leucine-rich glioma-inactivated protein 1, 0.7/100,000; collapsin response-mediator protein 5, 0.7/100,000; N-methyl-D-aspartate receptor, 0.6/100,000; antineuronal nuclear antibody type 2, 0.6/100,000; and glial fibrillary acidic protein α, 0.6/100,000.

INTERPRETATION

This study shows that the prevalence and incidence of autoimmune encephalitis are comparable to infectious encephalitis, and its detection is increasing over time. Ann Neurol 2018;83:166-177.

The Latino Physician Shortage: How the Affordable Care Act Increases the Value of Latino Spanish-Speaking Physicians and What Efforts Can Increase Their Supply

The United States Latino population is growing at a rapid pace and is set to reach nearly 30% by 2050. The demand for culturally and linguistically competent health care is increasing in lockstep with this growth; however, the supply of doctors with skills and experience suited for this care is lagging. In particular, there is a major shortage of Latino Spanish-speaking physicians, and the gap between demand and supply is widening. The implementation of the Affordable Care Act (ACA) has increased the capacity of the US healthcare system to care for the growing Latino Spanish-speaking population, through health insurance exchanges, increased funding for safety net institutions, and efforts to improve efficiency and coordination of care, particularly with Accountable Care Organizations and the Hospital Readmissions Reduction Program. With these policies in mind, the authors discuss how the value of Latino Spanish-speaking physicians to the healthcare system has increased under the environment of the ACA. In addition, the authors highlight key efforts to increase the supply of this physician population, including the implementation of the Deferred Action for Childhood Arrivals Act, premedical pipeline programs, and academic medicine and medical school education initiatives to increase Latino representation among physicians.

The role of neighborhood characteristics and the built environment in understanding racial/ethnic disparities in childhood obesity

BACKGROUND

Childhood obesity prevalence remains high and racial/ethnic disparities may be widening. Studies have examined the role of health behavioral differences. Less is known regarding neighborhood and built environment mediators of disparities. The objective of this study was to examine the extent to which racial/ethnic disparities in elevated child body mass index (BMI) are explained by neighborhood socioeconomic status (SES) and built environment.

METHODS

We collected and analyzed race/ethnicity, BMI, and geocoded address from electronic health records of 44,810 children 4 to 18years-old seen at 14 Massachusetts pediatric practices in 2011-2012. Main outcomes were BMI z-score and BMI z-score change over time. We used multivariable linear regression to examine associations between race/ethnicity and BMI z-score outcomes, sequentially adjusting for neighborhood SES and the food and physical activity environment.

RESULTS

Among 44,810 children, 13.3% were black, 5.7% Hispanic, and 65.2% white. Compared to white children, BMI z-scores were higher among black (0.43units [95% CI: 0.40-0.45]) and Hispanic (0.38 [0.34-0.42]) children; black (0.06 [0.04-0.08]), but not Hispanic, children also had greater increases in BMI z-score over time. Adjusting for neighborhood SES substantially attenuated BMI z-score differences among black (0.30 [0.27-0.34]) and Hispanic children (0.28 [0.23-0.32]), while adjustment for food and physical activity environments attenuated the differences but to a lesser extent than neighborhood SES.

CONCLUSIONS

Neighborhood SES and the built environment may be important drivers of childhood obesity disparities. To accelerate progress in reducing obesity disparities, interventions must be tailored to the neighborhood contexts in which families live.

Do patients hospitalised in high-minority hospitals experience more diversion and poorer outcomes? A retrospective multivariate analysis of Medicare patients in California

OBJECTIVE

We investigated the association between crowding as measured by ambulance diversion and differences in access, treatment and outcomes between black and white patients.

DESIGN

Retrospective analysis.

SETTING

We linked daily ambulance diversion logs from 26 California counties between 2001 and 2011 to Medicare patient records with acute myocardial infarction and categorised patients according to hours in diversion status for their nearest emergency departments on their day of admission: 0, <6, 6 to <12 and ≥ 12 h. We compared the amount of diversion time between hospitals serving high volume of black patients and other hospitals. We then use multivariate models to analyse changes in outcomes when patients faced different levels of diversion, and compared that change between black and white patients.

PARTICIPANTS

29,939 Medicare patients from 26 California counties between 2001 and 2011.

MAIN OUTCOME MEASURES

(1) Access to hospitals with cardiac technology; (2) treatment received; and (3) health outcomes (30-day, 90-day, and 1-year death and 30-day readmission).

RESULTS

Hospitals serving high volume of black patients spent more hours in diversion status compared with other hospitals. Patients faced with the highest level of diversion had the lowest probability of being admitted to hospitals with cardiac technology compared with those facing no diversion, by 4.4% for cardiac care intensive unit, and 3.4% for catheterisation laboratory and coronary artery bypass graft facilities. Patients experiencing increased diversion also had a 4.3% decreased likelihood of receiving catheterisation and 9.6% higher 1-year mortality.

CONCLUSIONS

Hospitals serving high volume of black patients are more likely to be on diversion, and diversion is associated with poorer access to cardiac technology, lower probability of receiving revascularisation and worse long-term mortality outcomes.

Racial and Ethnic Disparities in Health and Health Care: an Assessment and Analysis of the Awareness and Perceptions of Public Health Workers Implementing a Statewide Community Transformation Grant in Texas

INTRODUCTION

Little is known about the awareness of public health professionals regarding racial and ethnic disparities in health in the United States of America (USA). Our study objective was to assess the awareness and perceptions of a group of public health workers in Texas regarding racial health disparities and their chief contributing causes.

METHODS

We surveyed public health professionals working on a statewide grant in Texas, who were participants at health disparities' training workshops. Multivariable logistic regression was employed in examining the association between the participants' characteristics and their perceptions of the social determinants of health as principal causes of health disparities.

RESULTS

There were 106 respondents, of whom 38 and 35 % worked in health departments and non-profit organizations, respectively. The racial/ethnic groups with the highest incidence of HIV/AIDS and hypertension were correctly identified by 63 and 50 % of respondents, respectively, but only 17, and 32 % were knowledgeable regarding diabetes and cancer, respectively. Seventy-one percent of respondents perceived that health disparities are driven by the major axes of the social determinants of health. Exposure to information about racial/ethnic health disparities within the prior year was associated with a higher odds of perceiving that social determinants of health were causes of health disparities (OR 9.62; 95 % CI 2.77, 33.41).

CONCLUSION

Among public health workers, recent exposure to information regarding health disparities may be associated with their perceptions of health disparities. Further research is needed to investigate the impact of such exposure on their long-term perception of disparities, as well as the equity of services and programs they administer.

Racial Disparities in Comorbidities, Complications, and Maternal and Fetal Outcomes in Women With Preeclampsia/eclampsia

OBJECTIVE

The mechanisms leading to worse outcomes in African-American (AA) women with preeclampsia/eclampsia remain unclear. Our objective was to identify racial differences in maternal comorbidities, peripartum characteristics, and maternal and fetal outcomes.

METHODS/RESULTS

When compared to white women with preeclampsia/eclampsia, AA women had an increased unadjusted risk of inpatient maternal mortality (OR 3.70, 95% CI: 2.19-6.24). After adjustment for covariates, in-hospital mortality for AA women remained higher than that for white women (OR 2.85, 95% CI: 1.38-5.53), while the adjusted risk of death among Hispanic women did not differ from that for white women. We also found an increased risk of intrauterine fetal death (IUFD) among AA women. When compared to white women with preeclampsia, AA women had an increased unadjusted odds of IUFD (OR 2.78, 95% CI: 2.49-3.11), which remained significant after adjustment for covariates (adjusted OR 2.45, 95% CI: 2.14-2.82). In contrast, IUFD among Hispanic women did not differ from that for white women after adjusting for covariates.

CONCLUSIONS AND RELEVANCE

Our data suggest that African-American women are more likely to have risk factors for preeclampsia and more likely to suffer an adverse outcome during peripartum care. Future research should examine whether controlling co-morbidities and other risk factors will help to alleviate racial disparities in outcomes in this cohort of women.

Association Between Race and Case Fatality Rate in Hospitalizations for Sepsis

BACKGROUND

Differentiating whether disparities in outcomes for sepsis among racial groups are due to differences in hospital care versus pre-hospitalization factors is an important step in developing effective strategies to reduce these disparities. As such, we examined the association between race and case fatality rates among hospitalizations for sepsis.

METHODS

This was a case-control study of hospitalizations for sepsis in all acute-care, non-federal California hospitals during 2011. The association between hospital mortality and race was examined using hierarchical logistic regression analysis.

RESULTS

Among 131,831 hospitalizations for sepsis, the unadjusted case fatality rates were 15.1 % in whites, 14.0 % in blacks, 13.8 % in Hispanics, and 16.2 % in Asians (P < 0.001). Compared to whites, the odds of hospital mortality was 0.84 (95 % CI 0.79-0.89) for blacks, 0.88 (95 % CI 0.84-0.92) for Hispanics, and 0.93 (95 % CI 0.87-0.98) for Asians after controlling for patient, healthcare systems, and hospital-level factors. There was no difference in the variability of sepsis mortality across hospitals between racial groups. The range of case fatality rates for sepsis among hospitals was 8.3-22.9 % for whites, 9.1-20.5 % for blacks, 7.0-19.1 % for Hispanics, and 10.0-23.0 % for Asians.

CONCLUSION

Case fatality rates for sepsis hospitalizations are lower in minority racial groups in California. Future studies and interventions that seek to reduce racial disparities in sepsis need to focus on pre-hospitalization factors that contribute to population-level racial differences in sepsis outcomes.

Systematic review of racial disparities in human papillomavirus-associated anal dysplasia and anal cancer among men who have sex with men

We systematically reviewed the literature on anal human papillomavirus (HPV) infection, dysplasia, and cancer among Black and White men who have sex with men (MSM) to determine if a racial disparity exists. We searched 4 databases for articles up to March 2014. Studies involving Black MSM are nearly absent from the literature. Of 25 eligible studies, 2 stratified by race and sexual behavior. Both reported an elevated rate of abnormal anal outcomes among Black MSM. White MSM had a 1.3 times lower prevalence of group-2 HPV (P < .01) and nearly 13% lower prevalence of anal dysplasia than did Black MSM. We were unable to determine factors driving the absence of Black MSM in this research and whether disparities in clinical care exist. Elevated rates of abnormal anal cytology among Black MSM in 2 studies indicate a need for future research in this population.

Racial disparities in the use of catheter ablation for atrial fibrillation and flutter

BACKGROUND

Atrial fibrillation (AF) is the most common arrhythmia seen in clinical practice. Catheter ablation is an expensive but potentially curable treatment of AF. We explored differences in the use of catheter ablation for AF in the state of Florida and compared the findings to ablation for atrial flutter.

METHODS

We conducted a cross-sectional analysis of all ambulatory and hospital discharge procedures between 2006 and 2009 in Florida. We identified all subjects with AF and atrial flutter, using International Classification of Diseases, 9th Revision codes along with the race/ethnicity of each individual. We used logistic regression to determine the odds ratio (OR) of having a catheter ablation per disease by race and ethnicity adjusted for Charlson score, insurance status, year of the procedure, and facility location.

RESULTS

We identified 923,590 subjects with AF and 28,714 with atrial flutter. Catheter ablations were more commonly used in atrial flutter than in AF. The adjusted OR of having catheter ablation for AF for blacks was 0.67 (95% confidence interval [CI]: 0.60-0.75, P < 0.01), and for Hispanics it was 0.83 (95% CI: 0.75-0.91, P < 0.01) when compared to whites. The adjusted OR of having an ablation for atrial flutter for blacks was 1.08 (95% CI: 0.96-1.21, P = 0.16), and for Hispanics it was 0.90 (95% CI: 0.78-1.08, P = 0.20) when compared to whites.

CONCLUSIONS

In the state of Florida, black and Hispanic subjects with AF received less catheter ablations, whereas the same minority subjects with atrial flutter received a similar number of ablations compared to white subjects, with the same insurance and comorbidity burden.

Socioeconomic status. The relationship with health and autoimmune diseases

Socioeconomic status (SES) is a hierarchical social classification associated with different outcomes in health and disease. The most important factors influencing SES are income, educational level, occupational class, social class, and ancestry. These factors are closely related to each other as they present certain dependent interactions. Since there is a need to improve the understanding of the concept of SES and the ways it affects health and disease, we review herein the tools currently available to evaluate SES and its relationship with health and autoimmune diseases.

Healthcare disparities in critical illness

OBJECTIVE

To summarize the current literature on racial and gender disparities in critical care and the mechanisms underlying these disparities in the course of acute critical illness.

DATA SOURCES

MEDLINE search on the published literature addressing racial, ethnic, or gender disparities in acute critical illness, such as sepsis, acute lung injury, pneumonia, venous thromboembolism, and cardiac arrest.

STUDY SELECTION

Clinical studies that evaluated general critically ill patient populations in the United States as well as specific critical care conditions were reviewed with a focus on studies evaluating factors and contributors to health disparities.

DATA EXTRACTION

Study findings are presented according to their association with the prevalence, clinical presentation, management, and outcomes in acute critical illness.

DATA SYNTHESIS

This review presents potential contributors for racial and gender disparities related to genetic susceptibility, comorbidities, preventive health services, socioeconomic factors, cultural differences, and access to care. The data are organized along the course of acute critical illness.

CONCLUSIONS

The literature to date shows that disparities in critical care are most likely multifactorial involving individual, community, and hospital-level factors at several points in the continuum of acute critical illness. The data presented identify potential targets as interventions to reduce disparities in critical care and future avenues for research.

The impact of neighborhood socioeconomic status and race on the prescribing of opioids in emergency departments throughout the United States

BACKGROUND

Racial and ethnic disparities in opioid prescribing in the emergency department (ED) are well described, yet the influence of socioeconomic status (SES) remains unclear.

OBJECTIVES

(1) To examine the effect of neighborhood SES on the prescribing of opioids for moderate to severe pain; and (2) to determine if racial disparities in opioid prescribing persist after accounting for SES.

DESIGN

We used cross-sectional data from the National Hospital Ambulatory Medical Care Survey between 2006 and 2009 to examine the prescribing of opioids to patients presenting with moderate to severe pain (184 million visits). We used logistic regression to examine the association between the prescribing of opioids, SES, and race. Models were adjusted for age, sex, pain-level, injury-status, frequency of emergency visits, hospital type, and region.

MAIN MEASURES

Our primary outcome measure was whether an opioid was prescribed during a visit for moderate to severe pain. SES was determined based on income, percent poverty, and educational level within a patient's zip code.

RESULTS

Opioids were prescribed more frequently at visits from patients of the highest SES quartile compared to patients in the lowest quartile, including percent poverty (49.0 % vs. 39.4 %, P<0.001), household income (47.3 % vs. 40.7 %, P<0.001), and educational level (46.3 % vs. 42.5 %, P=0.01). Black patients were prescribed opioids less frequently than white patients across all measures of SES. In adjusted models, black patients (AOR 0.73; 95 % CI 0.66–0.81) and patients from poorer areas (AOR 0.76; 95 % CI 0.68–0.86) were less likely to receive opioids after accounting for pain-level, age, injury-status, and other covariates.

CONCLUSIONS

Patients presenting to emergency departments from lower SES regions were less likely to receive opioids for equivalent levels of pain than those from more affluent areas. Black and Hispanic patients were also less likely to receive opioids for equivalent levels of pain than whites, independent of SES.

Personalized healthcare in the era of value-based healthcare

Medical care in the USA is plagued by high costs, poor quality and fragmented care delivery. In response, new methods of integrated healthcare delivery are needed, including the patient-centered medical home. At the same time, we need to revitalize our approach to the practice of medicine, moving to a personalized approach, even as we increasingly focus on population management. Some aspects of personalized healthcare have the potential to add significant cost to the system, while others can improve value. This article aims to provide an overview of the current healthcare climate, discuss evolving models of care in the era of healthcare reform and describe the increasingly important role of personalized healthcare in this process.

Use of disease-modifying medications for rheumatoid arthritis by race and ethnicity in the National Ambulatory Medical Care Survey

OBJECTIVE

Disease-modifying antirheumatic drugs (DMARDs) are recommended for virtually all patients with rheumatoid arthritis (RA). We investigated the use of DMARDs in patients with RA in a nationally representative sample of visits to US physicians in the National Ambulatory Care Medical Survey (NAMCS).

METHODS

We analyzed the NAMCS visit data from 1996 through 2007 if the physician noted a diagnosis of RA. DMARD utilization was based on the medications listed by the physician. We used generalized linear models to examine the adjusted associations between DMARD use and potential predictors.

RESULTS

Of the 859 visits with a diagnosis code of RA identified over the study period, 404 visits (47%; 95% confidence interval [95% CI] 44-50%) had an associated DMARD. The percentage of RA visits with DMARDs increased slightly over the 12 years (P = 0.048), with biologic DMARDs increasing to 20% of visits after their introduction (P for trend <0.001). In fully adjusted models, African American race was associated with a 30% reduction in DMARD prescribing (risk ratio [RR] 0.70, 95% CI 0.48-1.00). A visit to a rheumatologist was the strongest correlate of DMARD prescribing (RR 2.33, 95% CI 1.89-2.86). Among visits to nonrheumatologists, African Americans were significantly less likely than whites to receive a DMARD (RR 0.39, 95% CI 0.17-0.92), but not among visits with rheumatologists (RR 0.81, 95% CI 0.52-1.27).

CONCLUSION

In the NAMCS, most visits coded with RA did not have an associated DMARD prescription. African Americans were less likely to receive DMARDs than whites, particularly when visiting nonrheumatologists.

Sickle cell disease in California: sociodemographic predictors of emergency department utilization

BACKGROUND

Patients with sickle cell disease (SCD) visit emergency departments (EDs) in rates leading to a significant health system burden. However, limited comprehensive evaluations of utilization patterns have been published using data connecting visits to patients across facilities. This study aims to examine sociodemographic predictors of ED utilization in SCD.

PROCEDURE

This retrospective cohort study employed 2007 data from the California Office of Statewide Health Planning and Development (OSHPD). Data included all ED encounters from California hospitals; identifiers connected each visit to an individual patient, across all facilities in the state. Multivariate regression techniques evaluated sociodemographic predictors of utilization while adjusting for confounding variables.

RESULTS

In 2007, 2,920 California patients with SCD made 16,364 ED visits. Adults ≥ 21 years of age had higher ED visit rates than children and were more likely to both be in the highest tier of users and visit multiple facilities. Patients living further from a self-identified provider of comprehensive SCD care had higher rates of ED visits and a lower likelihood of hospitalization from the ED. Publicly insured patients had higher rates of ED visits and were more likely to be in the highest tier of users than were the privately insured or uninsured.

CONCLUSIONS

Adulthood ≥ 21 years of age, distance from comprehensive SCD care, and insurance status are significant predictors of ED utilization in SCD. As a routine source of care decreases ED utilization, these findings prompt concern that these factors act as barriers to accessing comprehensive SCD care.

Sickle-cell disease in California: a population-based description of emergency department utilization

BACKGROUND

Acute and chronic clinical manifestations of sickle-cell disease (SCD) lead to significant healthcare utilization, especially of the emergency department (ED). Limited population-level data are available in SCD with the ability to connect patients to visits, leaving us with minimal description of utilization patterns.

PROCEDURE

Using ED discharge data with links between patients and visits, we sought to describe the California SCD population and its ED utilization patterns across facilities. Non-public California Office of Statewide Health Planning and Development data employ unique patient identifiers, linking patients, and visits.

RESULTS

SCD patients of all ages are heavily reliant on Medicaid (46%). The majority of SCD Californians visit an ED more than once during a year (69%), but only a minority use more than one facility during a year (34%). However, adults with SCD have multiple visits and utilize multiple EDs in higher proportions than do children (72% vs. 60% and 40% vs. 21%, respectively). A higher proportion of visits to the ED are made by SCD adults, but a higher proportion of visits by children result in hospital admission. Uninsured adults outnumber uninsured children (16% vs. 5%).

CONCLUSIONS

ED utilization by the California SCD population is described on a population level. Utilization patterns by adults point towards increased utilization in the population no longer eligible for Title V pediatric coverage for their disease. Further investigation using population-level socioeconomic and geographic correlates is warranted to evaluate the factors leading to ED utilization in SCD.

Acceptance rates in state-federal vocational rehabilitation of clients with brain injury: Is racial disparity an issue?

PRIMARY OBJECTIVE

To utilize Aday and Andersen's Framework for the Study of Access to examine racial disparity within the State-Federal vocational rehabilitation system, among clients with brain injury. Research questions included: Do pre-disposing characteristics such as age, race, ethnicity, gender, marital status and education influence vocational rehabilitation acceptance rates in the US? Do enabling characteristics such as referral source, insurance coverage and primary source of support at application influence vocational rehabilitation acceptance rates in the US? Is there a difference, based on race, in the reason for case closure for vocational rehabilitation services?

METHODS AND PROCEDURES

Exhaustive CHAID analysis was conducted with acceptance for rehabilitation as the criterion variable and pre-disposing characteristics as predictor variables. Chi-square analysis was calculated with regard to reason for closure.

MAIN OUTCOMES AND RESULTS

Descriptive findings are presented. Of the pre-disposing factors, the most significant predictor of acceptance rate was education level. Pearson Chi-square analyses revealed significant differences between White and non-White clients with brain injury with regard to reason for closure.

CONCLUSIONS

The data indicate that racial differences were only a small part of the overall equation and again that distinct disparity by race is not evidenced in the RSA-911 data for persons with a primary or secondary diagnosis of brain injury.

The influence of race/ethnicity and socioeconomic status on end-of-life care in the ICU

BACKGROUND

There is conflicting evidence about the influence of race/ethnicity on the use of intensive care at the end of life, and little is known about the influence of socioeconomic status.

METHODS

We examined patients who died in the ICU in 15 hospitals. Race/ethnicity was assessed as white and nonwhite. Socioeconomic status included patient education, health insurance, and income by zip code. To explore differences in end-of-life care, we examined the use of (1) advance directives, (2) life-sustaining therapies, (3) symptom management, (4) communication, and (5) support services.

RESULTS

Medical charts were abstracted for 3,138/3,400 patients of whom 2,479 (79%) were white and 659 (21%) were nonwhite (or Hispanic). In logistic regressions adjusted for patient demographics, socioeconomic factors, and site, nonwhite patients were less likely to have living wills (OR, 0.41; 95% CI, 0.32-0.54) and more likely to die with full support (OR, 1.59; 95% CI, 1.30-1.94). In documentation of family conferences, nonwhite patients were more likely to have documentation that prognosis was discussed (OR, 1.47; 95% CI, 1.21-1.77) and that physicians recommended withdrawal of life support (OR, 1.57; 95% CI, 1.11-2.21). Nonwhite patients also were more likely to have discord documented among family members or with clinicians (OR, 1.49; 95% CI, 1.04-2.15). Socioeconomic status did not modify these associations and was not a consistent predictor of end-of-life care.

CONCLUSIONS

We found numerous racial/ethnic differences in end-of-life care in the ICU that were not influenced by socioeconomic status. These differences could be due to treatment preferences, disparities, or both. Improving ICU end-of-life care for all patients and families will require a better understanding of these issues.

Patient perspectives of clinical care and patient navigation in follow-up of abnormal mammography

BACKGROUND

Racial and ethnic disparities in cancer care and survival are well documented. Patient navigation has been shown to improve timely follow-up of abnormal breast screenings for underserved patients. Few studies showed the impact of navigation on patient experiences of care.

OBJECTIVE

We compared the experiences of patients enrolled in a patient navigator program and non-navigated patients referred to a hospital breast center for follow-up of abnormal mammogram in an underserved community health center population.

DESIGN

Group comparison study using data from a mail and telephone survey to measure the experience of navigated and non-navigated patients.

PARTICIPANTS

English- and Spanish-speaking patients with abnormal mammography attending the Avon Breast Center between April 1, 2005 and April 30, 2007. Seventy-two navigated patients and 181 non-navigated patients completed surveys; the survey response rate was 53.6%.

MAIN MEASURES

Timeliness of care, preparation for the visit to the breast center, ease of access, quality of care, provider communication, unmet need and patient satisfaction.

KEY RESULTS

Most measures of the patient experience did not differ between navigated and non-navigated patients. Overall quality of care was rated as excellent (55% vs 62%, p = 0.294). Navigated patients were significantly more likely than non-navigated to 'definitely' understand what to expect at their visit (79% vs 60%, p = 0.003), to receive a reminder letter or telephone call (89% vs 77%, p = 0.029), and to feel welcome (89% vs 75%, p = 0.012). Navigated patients were less likely than non-navigated to rate the concern shown for their cultural/religious beliefs as excellent (45% vs 54%, p = 0.014).

CONCLUSIONS

Assessing patient perspectives is essential to evaluate the success of quality improvement interventions. In our center, we measured few significant disparities in the perceptions of care of these two very different populations of patients, although, there are still areas in which our program needs improvement. Further research is needed to understand the effectiveness of patient navigation programs in reducing racial and ethnic disparities.

Association between physician specialty and uptake of new medical technologies: HPV tests in Florida Medicaid

BACKGROUND

It is well established that specialists often adopt new medical technologies earlier than generalists, and that racial and ethnic minority patients are less likely than White patients to receive many procedures and prescription drugs. However, little is known about the role that specialists or generalists may play in reducing racial and ethnic disparities in uptake of new medical technologies. Human papillomavirus (HPV) DNA tests, introduced as a cervical cancer screening tool in 2000, present a rich context for exploring patterns of use across patient and provider subgroups.

OBJECTIVE

To identify patient characteristics and the provider specialty associated with overall and appropriate use of HPV DNA tests over time, and to examine the associations between clinical guidelines and adoption of the test in an underserved population.

DESIGN

Retrospective longitudinal study using Florida Medicaid administrative claims data.

PARTICIPANTS

Cervical cancer screening test claims for 415,239 female beneficiaries ages 21 to 64 from July 2001 through June 2006.

MAIN MEASURES

Overall and appropriate use of HPV DNA tests.

KEY RESULTS

Although minority women were initially less likely than White women to receive HPV DNA tests, test use grew more rapidly among Black and Hispanic women compared to White women. Obstetricians/gynecologists were significantly more likely than primary care providers to administer HPV DNA tests. Release of the first set of clinical guidelines was associated with a large increase in the use of HPV DNA tests (adjusted odds ratio: 2.46, p<0.0001); subsequent guidelines were associated with more modest increases.

CONCLUSIONS

Uptake of new cervical cancer screening protocols can occur quickly among traditionally underserved groups and may be aided by early adoption by specialists.

Prostate cancer treatment patterns among racial/ethnic groups in Florida

BACKGROUND

Prostate cancer is the second leading cause of cancer death among men in the United States. Blacks have the highest incidence and mortality rates. Treatment differences have been observed between black and white men. Brachy monotherapy (BMT) has become popular for localized prostate cancer because of its convenience, being the least invasive, and resulting in better quality of life during and after treatment. No studies have specifically examined BMT in treating localized prostate cancer by race/ethnicity.

OBJECTIVES

We sought to (1) describe treatment patterns among men with localized prostate cancer, (2) identify factors affecting the use of BMT, and (3) examine if there was any difference in BMT use by race and ethnicity.

METHODS

Florida cancer incidence data of 1994-2003 were used to extract information on men diagnosed with localized prostate cancer along with their demographics, primary payer at diagnosis, tumor stage and treatments. Logistic regression was performed to assess the likelihood of receiving BMT.

RESULTS

The study found that surgery and radiation were the 2 major single treatments for localized prostate cancer. The percent of patients receiving BMT treatment increased from 1994 through 2003. Men with the following characteristics were more likely to receive BMT than their counterparts: Non-Hispanic white, older, married, Medicare beneficiaries and military personnel, with well-differentiated tumor, and receiving treatment in facilities with high practice volume and/or located in urban counties.

CONCLUSION

There were racial/ethnic differences in localized prostate cancer treatment. Possible reasons for the differences require further research.

Black-White health disparities in the United States and Chicago: a 15-year progress analysis

OBJECTIVES

In an effort to examine national and Chicago, Illinois, progress in meeting the Healthy People 2010 goal of eliminating health disparities, we examined whether disparities between non-Hispanic Black and non-Hispanic White persons widened, narrowed, or stayed the same between 1990 and 2005.

METHODS

We examined 15 health status indicators. We determined whether a disparity widened, narrowed, or remained unchanged between 1990 and 2005 by examining the percentage difference in rates between non-Hispanic Black and non-Hispanic White populations at both time points and at each location. We calculated P values to determine whether changes in percentage difference over time were statistically significant.

RESULTS

Disparities between non-Hispanic Black and non-Hispanic White populations widened for 6 of 15 health status indicators examined for the United States (5 significantly), whereas in Chicago the majority of disparities widened (11 of 15, 5 significantly).

CONCLUSIONS

Overall, progress toward meeting the Healthy People 2010 goal of eliminating health disparities in the United States and in Chicago remains bleak. With more than 15 years of time and effort spent at the national and local level to reduce disparities, the impact remains negligible.

Severity of head computed tomography scan findings fail to explain racial differences in mortality following child abuse

INTRODUCTION

Differences in head injury severity may not be fully appreciated in child abuse victims. The purpose of this study was to determine if differential findings on initial head computed tomography (CT) scan could explain observed differential outcome by race.

METHODS

We identified 164 abuse patients from our trauma registry with an Injury Severity Score (ISS) > or = 15. Their initial head CT scan was graded from 1 to 4 (normal to severe). Statistical analysis was performed to asses the correlation between race, head CT grade, Glasgow Coma Scale (GCS) score, and mortality.

RESULTS

Overall mortality was 17%: 11% for white children, 32% for African-American children (P < .05). In review of the head CT scans there was no difference by race in types of injuries or head CT grade. Using a multivariate regression model, African-American race remained an independent risk factor for mortality with an odd ratio of 4.3 (95% confidence interval [CI] 1.6-11.5).

CONCLUSION

African-American children had a significantly higher mortality rate despite similar findings on initial head CT scans. Factors other than injury severity may explain these disparate outcomes.

Maternal care and birth outcomes among ethnic minority women in Finland

Background

Care during pregnancy and labour is of great importance in every culture. Studies show that people of migrant origin have barriers to obtaining accessible and good quality care compared to people in the host society. The aim of this study is to compare the access to and use of maternity services, and their outcomes among ethnic minority women having a singleton birth in Finland.

Methods

The study is based on data from the Finnish Medical Birth Register in 1999–2001 linked with the information of Statistics Finland on woman's country of birth, citizenship and mother tongue. Our study data included 6,532 women of foreign origin (3.9% of all singletons) giving singleton birth in Finland during 1999–2001 (compared to 158,469 Finnish origin singletons).

Results

Most women have migrated during the last fifteen years, mainly from Russia, Baltic countries, Somalia and East Europe. Migrant origin women participated substantially in prenatal care. Interventions performed or needed during pregnancy and childbirth varied between ethnic groups. Women of African and Somali origin had most health problems resulted in the highest perinatal mortality rates. Women from East Europe, the Middle East, North Africa and Somalia had a significant risk of low birth weight and small for gestational age newborns. Most premature newborns were found among women from the Middle East, North Africa and South Asia. Primiparous women from Africa, Somalia and Latin America and Caribbean had most caesarean sections while newborns of Latin American origin had more interventions after birth.

Conclusion

Despite good general coverage of maternal care among migrant origin women, there were clear variations in the type of treatment given to them or needed by them. African origin women had the most health problems during pregnancy and childbirth and the worst perinatal outcomes indicating the urgent need of targeted preventive and special care. These study results do not confirm either healthy migrant effect or epidemiological paradox according to which migrant origin women have considerable good birth outcomes.

Racial and ethnic differences in end-of-life costs: why do minorities cost more than whites?

BACKGROUND

Racial and ethnic minorities generally receive fewer medical interventions than whites, but racial and ethnic patterns in Medicare expenditures and interventions may be quite different at life's end.

METHODS

Based on a random, stratified sample of Medicare decedents (N = 158 780) in 2001, we used regression to relate differences in age, sex, cause of death, total morbidity burden, geography, life-sustaining interventions (eg, ventilators), and hospice to racial and ethnic differences in Medicare expenditures in the last 6 months of life.

RESULTS

In the final 6 months of life, costs for whites average $20,166; blacks, $26,704 (32% more); and Hispanics, $31,702 (57% more). Similar differences exist within sexes, age groups, all causes of death, all sites of death, and within similar geographic areas. Differences in age, sex, cause of death, total morbidity burden, geography, socioeconomic status, and hospice use account for 53% and 63% of the higher costs for blacks and Hispanics, respectively. While whites use hospice most frequently (whites, 26%; blacks, 20%; and Hispanics, 23%), racial and ethnic differences in end-of-life expenditures are affected only minimally. However, fully 85% of the observed higher costs for nonwhites are accounted for after additionally modeling their greater end-of-life use of the intensive care unit and various intensive procedures (such as, gastrostomies, used by 10.5% of blacks, 9.1% of Hispanics, and 4.1% of whites).

CONCLUSIONS

At life's end, black and Hispanic decedents have substantially higher costs than whites. More than half of these cost differences are related to geographic, sociodemographic, and morbidity differences. Strikingly greater use of life-sustaining interventions accounts for most of the rest.

Racial differences in the evaluation and treatment of hepatitis C among veterans: a retrospective cohort study

OBJECTIVES

We examined the association between race and hepatitis C virus (HCV) evaluation and treatment of veterans in the Northwest Network of the Department of Veterans Affairs (VA).

METHODS

In our retrospective cohort study, we used medical records to determine antiviral treatment of 4263 HCV-infected patients from 8 VA medical centers. Secondary outcomes included specialty referrals, laboratory evaluation, viral genotype testing, and liver biopsy. Multiple logistic regression was used to adjust for clinical (measured through laboratory results and International Classification of Diseases, Ninth Revision, codes) and sociodemographic factors.

RESULTS

Blacks were less than half as likely as Whites to receive antiviral treatment (odds ratio [OR]=0.38; 95% confidence interval [CI]=0.23, 0.63). Both had similar odds of referral and liver biopsy. However, Blacks were significantly less likely to have complete laboratory evaluation (OR=0.67; 95% CI=0.52, 0.88) and viral genotype testing (OR=0.68; 95% CI=0.51, 0.90).

CONCLUSIONS

Race is associated with receipt of medical care for various medical conditions. Further investigation is warranted to help understand whether patient preference or provider bias may explain why HCV-infected Blacks were less likely to receive medical care than Whites.

Differences in utilization of drug-eluting stents by race and payer

Numerous disparities in access to health care by race and gender have been identified in the literature. This study examines differences in the use of drug-eluting stents (DES) versus bare-metal stents (BMS) by race, payer, and income level. Data from New York State's Percutaneous Coronary Intervention Reporting System from July 2003 to December 2004 were used to examine use of DES (20,165 patients) relative to BMS (4,547 patients) by race, payer, and annual income level, controlling for a variety of patient and hospital characteristics. African-Americans were found to be less likely to receive DES than other races between July 2003 and March 2004 (adjusted odds ratio [OR] 0.56, 95% confidence interval [CI] 0.50 to 0.65) and between April 2004 and December 2004 (adjusted OR 0.74, 95% CI 0.61 to 0.90). These disparities were reduced (respective adjusted ORs 0.67, 95% CI 0.58 to 0.77 and 0.81, 95% CI 0.66 to 0.91) when controlling for admitting hospital and hospital volume, but were still significant. Medicaid/self-pay patients, and patients living in zip codes with median annual incomes between $20,000 and $30,000 were also less likely to receive DES in the first time period (adjusted respective ORs 0.80, 95% CI 0.68 to 0.93) and 0.85, 95% CI 0.75 to 0.96). In conclusion, African-Americans and low income groups receive DES less frequently than their counterparts compared with BMS. This is related to the hospitals where they are admitted, but not entirely.

Tolerability, safety, and efficacy of beta-blockade in black patients with heart failure in the community setting: insights from a large prospective beta-blocker registry

Heart failure (HF) clinical trials suggest different responses of blacks and whites to beta-blockers. Differences between clinical trial and community settings may also have an impact. The Carvedilol Heart Failure Registry (COHERE) observed experience with carvedilol in 4280 patients with HF in a community setting. This analysis compares characteristics, outcomes, and carvedilol dosing of blacks and whites in COHERE. Compared with whites (n=3433), blacks (n=523) had more severe HF symptoms despite similar systolic function. At similar carvedilol maintenance doses, symptoms improved in 33% of blacks vs 28% of whites, while worsening in 10% and 11%, respectively (both nonsignificant), and HF hospitalization rates were reduced comparably in both groups (-58% vs -56%, respectively; both P<.001). Incidence and hazard ratios of death were similar in blacks and whites (6.9% vs 7.5%, hazard ratio 1.2 vs 1.0, P=.276). Thus carvedilol was similarly effective in blacks and whites with HF in the community setting, consistent with carvedilol clinical trials.

African American race was associated with an increased risk of complications following venous thromboembolism

OBJECTIVE

Limited data exist on the quality of care for patients with venous thromboembolism (VTE), and it is unknown whether the processes and outcomes of care for this illness differ between African Americans and whites.

STUDY DESIGN AND SETTING

We retrospectively studied 168 patients hospitalized for VTE in two Veterans Affairs hospitals during fiscal years 2000-2002. Patient characteristics, information about processes of care, and medical outcomes at 90 days after the index VTE event were abstracted from medical records. We used logistic regression to explore associations between race, processes of care, and the overall 90-day complication rate (i.e., death, bleeding, or recurrent VTE), adjusting for patient baseline characteristics.

RESULTS

Multivariable analysis demonstrated that administration of warfarin within 1 day of starting heparin (odds ratio [OR] 0.20, 95% confidence interval [CI]: 0.05-0.42) and overlap of heparin and warfarin treatment >or=4 days (OR 0.09, 95% CI: 0.02-0.50) were associated with a lower complication rate, and African American race was associated with a higher complication rate (OR 5.2, 95% CI: 1.3-21.6). Race was not significantly associated with the performance of processes of care in multivariable analysis.

CONCLUSION

Although African Americans had an increased risk of complications following VTE, race was not independently associated with the use of processes of care for VTE.

High prevalence of skin test positivity in severe or difficult-to-treat asthma

BACKGROUND

Skin tests are considered the gold standard for detecting allergen-specific immunoglobulin E (IgE) in the clinical setting and are an important tool for diagnosing and managing allergic asthma.

OBJECTIVE

To assess the prevalence of skin testing in patients > or = 12 years enrolled in The Epidemiology and Natural History of Asthma: Outcomes and Treatment Regimens (TENOR) study.

METHODS

Patients were asked whether they had ever been skin tested and, if so, they were asked to provide the test results. Clinical characteristics were used to compare positive (ST+), negative (ST-), and skin test not done (STND) patients.

RESULTS

Of 2,985 patients eligible, 85.8% recalled being skin tested. Of those tested, 93.5% were positive (allergist 95.7%, pulmonologist 87.3%). A high proportion of Whites (93.5%) and non-Whites (94.0%) were ST+; however, more non-Whites had never been skin tested (21.7% vs. 12.3%, respectively; p < 0.0001). Total serum IgE was 104.6 IU/mL for ST+ patients, 87.1 IU/mL for STND patients, and 32.4 IU/mL for ST- patients. Age at asthma onset, duration of asthma, and the prevalence of atopic disorders and asthma triggers differentiated the ST+ from the ST- group. Disease severity appeared similar between the two groups. In general, values for STND patients were closer to the ST+ group, suggesting that those not tested would have been ST+ if administered a test.

CONCLUSIONS

The prevalence of ST+ patients was high in allergy and pulmonology practices, and in White and non-White patients. These data support the utility of a more complete allergic evaluation in severe asthmatics. Skin testing appears associated with disease pathophysiologies in asthma.

Social processes used by African American women in making decisions about mammography screening

PURPOSE

To describe the social processes used by African American (AA) women ages > or = 50 years in making decisions about mammography screening.

DESIGN

Grounded theory methodology.

METHODS

Tape-recorded interviews with a researcher-designed, semi-structured interview guide with an initial and theoretical sample of 30 AA women ages 52 to 71 of diverse socioeconomic status. Interviews occurred in various settings such as the church rectory, women's homes, and work settings. Extensive written field notes and tapes were transcribed verbatim immediately after the interviews by an experienced transcriptionist.

FINDINGS

The women's decisions about mammography screening were associated with five social processes: (a) acknowledging prior experiences with healthcare providers and systems; (b) reporting fears and fatalistic beliefs of breast cancer and related treatment; (c) valuing the opinions of significant others; (d) relying on religious beliefs and supports; and (e) caregiving responsibilities of significant others. The processes were further differentiated by three distinct decision-making styles: taking charge, enduring, and protesting.

CONCLUSIONS

Each of the social processes was reported equally and emphasized by the diverse sample of AA women in decisions related to mammography screening. Mammography screening decisions were heavily influenced by caregiving responsibilities. Further research is needed to explain and understand this social process on the health and well-being of AA women over time.

Eight Americas: investigating mortality disparities across races, counties, and race-counties in the United States

BACKGROUND

The gap between the highest and lowest life expectancies for race-county combinations in the United States is over 35 y. We divided the race-county combinations of the US population into eight distinct groups, referred to as the "eight Americas," to explore the causes of the disparities that can inform specific public health intervention policies and programs.

METHODS AND FINDINGS

The eight Americas were defined based on race, location of the county of residence, population density, race-specific county-level per capita income, and cumulative homicide rate. Data sources for population and mortality figures were the Bureau of the Census and the National Center for Health Statistics. We estimated life expectancy, the risk of mortality from specific diseases, health insurance, and health-care utilization for the eight Americas. The life expectancy gap between the 3.4 million high-risk urban black males and the 5.6 million Asian females was 20.7 y in 2001. Within the sexes, the life expectancy gap between the best-off and the worst-off groups was 15.4 y for males (Asians versus high-risk urban blacks) and 12.8 y for females (Asians versus low-income southern rural blacks). Mortality disparities among the eight Americas were largest for young (15-44 y) and middle-aged (45-59 y) adults, especially for men. The disparities were caused primarily by a number of chronic diseases and injuries with well-established risk factors. Between 1982 and 2001, the ordering of life expectancy among the eight Americas and the absolute difference between the advantaged and disadvantaged groups remained largely unchanged. Self-reported health plan coverage was lowest for western Native Americans and low-income southern rural blacks. Crude self-reported health-care utilization, however, was slightly higher for the more disadvantaged populations.

CONCLUSIONS

Disparities in mortality across the eight Americas, each consisting of millions or tens of millions of Americans, are enormous by all international standards. The observed disparities in life expectancy cannot be explained by race, income, or basic health-care access and utilization alone. Because policies aimed at reducing fundamental socioeconomic inequalities are currently practically absent in the US, health disparities will have to be at least partly addressed through public health strategies that reduce risk factors for chronic diseases and injuries.

Understanding the provider contribution to race/ethnicity disparities in pain treatment: insights from dual process models of stereotyping

OBJECTIVE

This article applied dual process models of stereotyping to illustrate how various psychological mechanisms may lead to unintentional provider bias in decisions about pain treatment. Stereotypes have been shown to influence judgments and behaviors by two distinct cognitive processes, automatic stereotyping and goal-modified stereotyping, which differ both in level of individual conscious control and how much they are influenced by the goals in an interaction. Although these two processes may occur simultaneously and are difficult to disentangle, the conceptual distinction is important because unintentional bias that results from goal-modified rather than automatic stereotyping requires different types of interventions. We proposed a series of hypotheses that showed how these different processes may lead providers to contribute to disparities in pain treatment: 1) indirectly, by influencing the content and affective tone of the clinical encounter; and 2) directly, by influencing provider decision making. We also highlighted situations that may increase the likelihood that stereotype-based bias will occur and suggested directions for future research and interventions.

Unequal Use of New Technologies by Race: The Use of New Prostate Surgeries (Transurethral Needle Ablation, Transurethral Microwave Therapy and Laser) Among Elderly Medicare Beneficiaries

PURPOSE

We compared the availability and use of transurethral microwave therapy, transurethral needle ablation, contact or noncontact laser therapy and transurethral resection of the prostate among elderly black and white Medicare beneficiaries.

MATERIALS AND METHODS

We examined 100% Medicare Inpatient, Outpatient, Carrier and Denominator files of men 65 years old or older who underwent these procedures in 1999 through 2001. White-to-black race rate ratios for each procedure were computed for the entire United States, as well as for a restricted set of counties in which procedures were available to black beneficiaries.

RESULTS

A total of 170,067 TURP, 16,953 TUMT, 5,353 TUNA and 12,134 Laser procedures were performed during 3 years. Nationally there was only a 3% difference in the age adjusted TURP rates between white and black men (6.13 and 5.94 per 1,000 person-years, respectively). However, the age adjusted rates for TUMT and TUNA among white men were about twice those among black men (0.63 vs 0.31 and 0.20 vs 0.10 per 1,000 person-years, respectively). Laser rates were 17% higher among white men than among black men (0.44 vs 0.38 per 1,000 person-years). Large geographic variation existed in the new procedure rates. Negative binomial regression analysis confirmed the national findings in those counties in which the procedures were available to black men. Adjusted white-to-black rate ratios were 1.96 (95% CI 1.70-2.25) for TUMT, 2.33 (95% CI 1.87-2.90) for TUNA and 1.36 (95% CI 1.16-1.59) for Laser.

CONCLUSIONS

After controlling for availability, elderly black Medicare beneficiaries were less likely to undergo the new BPH procedures than white beneficiaries, while the usage difference for TURP remained small.

Quality of care in African-American patients admitted for congestive heart failure at a university teaching hospital

Previous studies have shown that the quality of congestive heart failure (CHF) treatment for hospitalized patients varies. The goal of this study was to evaluate the compliance of physicians at a large, inner-city teaching hospital with current evidence-based guidelines. A retrospective review of the medical records of 104 patients admitted with CHF was conducted. Quality-of-care indicators were assessed, including the use of echocardiograms, the administration of angiotensin-converting enzyme (ACE) inhibitors and beta blockers to appropriate patients, and lifestyle and medication counseling at discharge. The assessment of left ventricular (LV) function was documented in 96.1% of patients (n = 100). A total of 65 patients (92.8%) with systolic dysfunction were considered to be ideal candidates for ACE inhibitor therapy. Of these 65 patients, 58 (89.2%) were discharged on ACE inhibitors. Of 41 patients with LV systolic dysfunction who were considered to be ideal candidates for beta-blocker therapy, only 10 (24.4%) were discharged on beta-blocker therapy. Of all patients with CHF, 50% received discharge counseling on medication compliance, 48% received counseling on a low-salt diet, and only 9% were told to monitor daily weight. This study shows that in a major academic teaching hospital, there is a need for improvement in the use of beta-blocker therapy as well as greater emphasis on patient education strategies regarding diet, medication adherence, and monitoring daily weight.

Patterns and predictors of prescription medication use in the management of headache: findings from the 2000 Medical Expenditure Panel Survey

OBJECTIVE

The primary objectives were to examine national trends of prescription medication use for headache and explore patterns of variation in the use of these medications across social and demographic levels.

BACKGROUND

Despite widespread use of prescription medication for management of headache, little is known about utilization patterns or patient characteristics associated with receiving this type of treatment.

METHODS

This study conducted a secondary analysis of data obtained during the 2000 Medical Expenditure Panel Survey, a representative survey of the U.S. noninstitutionalized population. Weighted descriptive statistics and logistic regression models were used to evaluate patterns and rates of overall prescription medication use in patients reporting headache as a household condition.

RESULTS

An estimated 9.7 million people 18 years or older reported suffering from headache in 2000. Of these, 46% reported using at least one medication for the treatment of headache. Migraine-specific abortive medication (ie, selective serotonin receptor agonists and ergotamine derivatives) was the most frequently reported medication class, used by 36% of participants. Opiate analgesics and butalbital-containing products also experienced extensive prescribing reported by 22% and 17% of survey respondents, respectively. After adjustment for covariates, wide variation in the use of prescription medication was observed across sociodemographic characteristics including age, ethnicity, and insurance status.

CONCLUSION

The observed variation in prescription medication use by drug class and sociodemographic characteristics suggests strategies are needed for improving current prescribing patterns in this patient population.
