Health disparities--less talk, more action

Social Deprivation and Post-TAVR Outcomes in Ontario, Canada: A Population-Based Study

Background Transcatheter aortic valve replacement (TAVR)/intervention has become the standard of care for treatment of severe aortic stenosis across the spectrum of risk. There are socioeconomic disparities in access to TAVR. The impact of these disparities on postprocedural outcomes remains unknown. Our objective was to examine the association between neighborhood-level social deprivation and post-TAVR mortality and hospital readmission. Methods and Results We conducted a population-based retrospective cohort study of all 4145 patients in Ontario, Canada, who received TAVR from April 1, 2017, to March 31, 2020. Our co-primary outcomes were 1-year postprocedure mortality and 1-year postprocedure readmission. Using Cox proportional hazards models for mortality and cause-specific competing risk hazard models for readmission, we evaluated the relationship between neighborhood-level measures of residential instability, material deprivation, and concentration of racial and ethnic groups with post-TAVR outcomes. After multivariable adjustment, we found a statistically significant relationship between residential instability and postprocedural 1-year mortality, ranging from a hazard ratio of 1.64 to a hazard ratio of 2.05. There was a significant association between the highest degree of residential instability and 1-year readmission (hazard ratio, 1.23 [95% CI, 1.01-1.49]). There was no association between material deprivation and concentration of racial and ethnic groups with post-TAVR outcomes. Conclusions Residential instability was associated with increased risk for post-TAVR mortality, and the highest quintile of residential instability was associated with increased post-TAVR readmission. To reduce health disparities and promote an equitable health care system, further research and policy interventions will be required to identify and support economically and socially minoritized patients undergoing TAVR.

The Role of Transportation in the Enrollment of Elderly African Americans into Exercise and Memory Study: GEMS Study

BACKGROUND

Understanding the factors driving recruitment and enrollment of African Americans (AA)s in clinical translational research will assure that underrepresented populations benefit from scientific progress and new developments in the diagnosis and treatment of Alzheimer's disease and related disorders. While transportation is pivotal to volunteers' ability to participate in research, its contribution to enrollment in exercise studies on AD is yet to be elucidated. Thus, this research focuses on identifying factors that influence the recruitment and enrollment of African Americans in biomedical studies and determining whether the availability of transportation motivates participation in time-demanding exercise studies on AD.

METHODS

We analyzed recruitment data collected from 567 volunteers ages 55 and older screened through various recruitment sources and considered for enrollment in our exercise and memory study. To determine whether transportation influenced the enrollment of African Americans (AA)s in biomedical studies, multiple logistic regression analysis was performed to identify significant factors that drive enrollment. Furthermore, the association of race and demographic factors on the availability of transportation was assessed.

RESULTS

Demographic factors, age at screening, education, gender, and cognitive scores were not significantly different among those enrolled compared to control (not-enrolled). In the relationship of enrollment to transportation, enrolled participants were more likely to have access to transportation (79.12%) than not-enrolled participants who had less access to transportation (71.6%); however, the association was not statistically significant. However, race differentially influenced the likelihood of enrollment, with elderly AAs being significantly less likely to have transportation (p = 0.020) than the Whites but more likely than "others" to have transportation.

CONCLUSION

Our findings suggest that access to transportation may be a key factor motivating enrollment in an exercise and memory study in a predominantly AA sample. Notably, AAs in our sample were less likely to have transportation than Whites. Other demographic factors and cognitive scores did not significantly influence enrollment in our sample. A larger sample and more detailed assessment of transportation are needed to further discern the role of transportation in clinical trials.

Exploring associations between social determinants of health and mental health outcomes in families from socioeconomically and racially and ethnically diverse households

This cross-sectional study investigated the associations between Social Determinants of Health (SDOH) and mental health outcomes of parents and children (n = 1307) from the Latinx, Native American, Somali/Ethiopian, White, Hmong, and African American communities. Logistic regression models were used to estimate the adjusted associations between five parent and child mental health measures and 25 measures of SDOH. False discovery rate q-values were computed to account for multiple comparisons. Families of color reported 5.3-7.8 SDOH barriers while White families reported 1.7 SDOH barriers on average. Adjusted analyses indicated that low family functioning and high perceived discrimination were associated with low resiliency among parents and increased behavioral difficulties among children. Other SDOH that were adversely associated with parent or child mental health included lack of social support, recent stressful life events, and adverse childhood experiences among parents. SDOH in the social and community context were most likely to be associated with mental health problems. Community-engaged evidence-based interventions are needed to improve population mental health.

Development and validation of an organizational readiness to change instrument focused on cultural competency

OBJECTIVE

To validate a brief survey developed to be used in hospitals nationwide to assess organizational readiness to change to increase cultural competency.

DATA SOURCES/STUDY SETTING

Analysis of primary data collected as part of a 125-item Organizational Assessment Survey conducted in the ten US hospitals participating in the Robert Wood Johnson Foundation Expecting Success program in 2005-2006.

STUDY DESIGN

The study utilized a cross-sectional survey.

DATA COLLECTION

Surveys were distributed to participants in the ten hospitals based on job title and role within the organization (including clinicians, clinical administrators, other clinical professionals, and those in relevant nonclinical roles; respondents = 513; response rate = 31%). Missing data were deleted listwise. We computed internal consistency reliability via Cronbach's alpha and interrater agreement using the r_wg(j) index, and conducted exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to examine validity of the survey. We subsequently conducted ANOVAs to examine whether the instrument adequately distinguished between hospitals.

PRINCIPAL FINDINGS

Across 408 complete responses, a scree plot generated by the EFA and a follow-up CFA indicated a 2-factor solution (RMSEA = 0.06; CFI = 0.96; GFI = 0.96; RMSR = 0.08). We identified these primary factors as two scales, a 12-item Readiness to Address Quality scale (α = 0.85; r_wg(j)  = 0.93) and an 11-item Readiness to Address Disparities scale (α = 0.65; r_wg(j)  = 0.89). ANOVAs suggested that these scales distinguished between hospitals (RTAQ: F[9, 428] = 3.70, P < .001; RTAD: F[9, 435] = 3.02, P = .002).

CONCLUSIONS

This survey can help identify an organization's readiness to change to increase cultural competency.

Gender differences in the surgical management of lumbar degenerative disease: a scoping review

OBJECTIVE

Despite efforts toward achieving gender equality in clinical trial enrollment, females are often underrepresented, and gender-specific data analysis is often unavailable. Identifying and reducing gender bias in medical decision-making and outcome reporting may facilitate equitable healthcare delivery. Gender disparity in the utilization of surgical therapy has been exemplified in the orthopedic literature through studies of total joint arthroplasty. A paucity of literature is available to guide the management of lumbar degenerative disease, which stratifies on the basis of demographic factors. The objective of this study was to systematically map and synthesize the adult surgical literature regarding gender differences in pre- and postoperative patient-reported clinical assessment scores for patients with lumbar degenerative disease (disc degeneration, disc herniation, spondylolisthesis, and spinal canal stenosis).

METHODS

A systematic scoping review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. MEDLINE, Embase, and the Cochrane Registry of Controlled Trials were searched from inception to September 2018. Study characteristics including patient demographics, diagnoses, procedures, and pre- and postoperative clinical assessment scores (pain, disability, and health-related quality of life [HRQoL]) were collected.

RESULTS

Thirty articles were identified, accounting for 32,951 patients. Six studies accounted for 84% of patients; 5 of the 6 studies were published by European groups. The most common lumbar degenerative conditions were disc herniation (59.0%), disc degeneration (20.3%), and spinal canal stenosis (15.9%). The majority of studies reported worse preoperative pain (93.3%), disability (81.3%), and HRQoL (75%) among females. The remainder reported equivalent preoperative scores between males and females. The majority of studies (63.3%) did not report preoperative duration of symptoms, and this represents a limitation of the data. Eighty percent of studies found that females had worse absolute postoperative scores in at least one outcome category (pain, disability, or HRQoL). The remainder reported equivalent absolute postoperative scores between males and females. Seventy-three percent of studies reported either an equivalent or greater interval change for females.

CONCLUSIONS

Female patients undergoing surgery for lumbar degenerative disease (disc degeneration, disc herniation, spondylolisthesis, and spinal canal stenosis) have worse absolute preoperative pain, disability, and HRQoL. Following surgery, females have worse absolute pain, disability, and HRQoL, but demonstrate an equal or greater interval change compared to males. Further studies should examine gender differences in preoperative workup and clinical course.

Healthcare disparities among orthopedic trauma patients in the USA: socio-demographic factors influence the management of calcaneus fractures

Background

Socio-demographic factors have been suggested to contribute to differences in healthcare utilization for several elective orthopedic procedures. Reports on disparities in utilization of orthopedic trauma procedures remain limited. The purpose of our study is to assess the roles of clinical and socio-demographic variables in utilization of operative fixation of calcaneus fractures in the USA.

Methods

The National Inpatient Sample (NIS) dataset was used to analyze all patients from 2005 to 2014 with closed calcaneal fractures. Multivariate logistic regression analyses were performed to evaluate the impact of clinical and socio-demographic variables on the utilization of surgical versus non-surgical treatment.

Results

A total of 17,156 patients with closed calcaneus fractures were identified. Operative treatment was rendered in 7039 patients (41.03%). A multivariate logistic regression demonstrated multiple clinical and socio-demographic factors to significantly influence the utilization of surgical treatment including age, gender, insurance status, race/ethnicity, income, diabetes, peripheral vascular disease, psychosis, drug abuse, and alcohol abuse (p <  0.05). In addition, hospital size and hospital type (teaching versus non-teaching) showed a statistically significant difference (p <  0.05).

Conclusions

Besides different clinical variables, we identified several socio-demographic factors influencing the utilization of surgical treatment of calcaneus fractures in the US patient population. Further studies need to identify the specific patient-related, provider-related, and system-related factors leading to these disparities.

Poverty-Related Diseases College: a virtual African-European network to build research capacity

The Poverty-Related Diseases College was a virtual African-European college and network that connected young African and European biomedical scientists working on poverty-related diseases. The aim of the Poverty-Related Diseases College was to build sustainable scientific capacity and international networks in poverty-related biomedical research in the context of the development of Africa. The Poverty-Related Diseases College consisted of three elective and mandatory training modules followed by a reality check in Africa and a science exchange in either Europe or the USA. In this analysis paper, we present our experience and evaluation, discuss the strengths and encountered weaknesses of the programme, and provide recommendations to policymakers and funders.

Impact of Race and Gender on Utilization Rate of Total Shoulder Arthroplasty

Marked underutilization rates of total joint arthroplasty in minorities compared with nonminorities exist, with a paucity of literature surrounding inequities related to total shoulder arthroplasty (TSA). Using the Statewide Planning and Research Cooperative System database, patients who underwent elective TSA in New York State (NYS) were identified and characterized by age, race, gender, medical comorbidities, and payor status. Patients were stratified into 4 separate 5-year periods from 1990 to 2009. Comorbidity severity was defined using the Elixhauser criteria. A total of 10,538 elective TSAs were identified, with half of the procedures occurring in the most recent time quartile. Whites accounted for 70% of the procedures, whereas blacks accounted for 5%. During the 20-year period, the age-adjusted incidence of TSA in white men and women increased by 417% and 421%, respectively, whereas the incidence for black men and women increased by 378% and 329%, respectively. Black men had the lowest utilization rate among all subgroups, and overall disparity between races continued to widen over time. Blacks had significantly more comorbid conditions (P<.001) than whites when undergoing TSA. Blacks were more likely to have Medicaid insurance and less participation in Medicare (P<.001). Racial and gender disparities clearly exist in TSA utilization rates in NYS and may be worsening. Although reasons for these disparities are likely multifactorial, a deeper understanding of the factors involved in patient selection and access to care is necessary to appropriately address these disparities and effect change at a system-wide patient and provider level.

Racial disparities in outcomes after cardiac surgery: the role of hospital quality

Patients from racial and ethnic minorities experience higher mortality after cardiac surgery compared to white patients, both during the early postoperative phase as well as long term. A number of factors likely explain poor outcomes in black and minority patients, which include differences in biology, comorbid health conditions, socioeconomic background, and quality of hospital care. Recent evidence suggests that a major factor underlying excess mortality in these groups is due to their over-representation in low-quality hospitals, where all patients regardless of race have worse outcomes. In this review, we examine the factors underlying racial disparities in outcomes after cardiac surgery, with a primary focus on the role of hospital quality.

Attention to local health burden and the global disparity of health research

Most studies on global health inequality consider unequal health care and socio-economic conditions but neglect inequality in the production of health knowledge relevant to addressing disease burden. We demonstrate this inequality and identify likely causes. Using disability-adjusted life years (DALYs) for 111 prominent medical conditions, assessed globally and nationally by the World Health Organization, we linked DALYs with MEDLINE articles for each condition to assess the influence of DALY-based global disease burden, compared to the global market for treatment, on the production of relevant MEDLINE articles, systematic reviews, clinical trials and research using animal models vs. humans. We then explored how DALYs, wealth, and the production of research within countries correlate with this global pattern. We show that global DALYs for each condition had a small, significant negative relationship with the production of each type of MEDLINE articles for that condition. Local processes of health research appear to be behind this. Clinical trials and animal studies but not systematic reviews produced within countries were strongly guided by local DALYs. More and less developed countries had very different disease profiles and rich countries publish much more than poor countries. Accordingly, conditions common to developed countries garnered more clinical research than those common to less developed countries. Many of the health needs in less developed countries do not attract attention among developed country researchers who produce the vast majority of global health knowledge—including clinical trials—in response to their own local needs. This raises concern about the amount of knowledge relevant to poor populations deficient in their own research infrastructure. We recommend measures to address this critical dimension of global health inequality.

The role of at-risk alcohol/drug use and treatment in appointment attendance and virologic suppression among HIV(+) African Americans

The causes of poor clinic attendance and incomplete virologic suppression among HIV(+) African Americans (AAs) are not well understood. We estimated the effect of at-risk alcohol/drug use and associated treatment on attending scheduled appointments and virologic suppression among 576 HIV(+) AA patients in the University of Alabama at Birmingham (UAB) 1917 Clinic Cohort who contributed 591 interviews to the analysis. At interview, 78% of patients were new to HIV care at UAB, 38% engaged in at-risk alcohol/drug use or received associated treatment in the prior year, while the median (quartiles) age and CD4 count were 36 (28; 46) years and 321 (142; 530) cells/μl, respectively. In the 2 years after an interview, half of the patients had attended at least 82% of appointments while half had achieved virologic suppression for at least 71% of RNA assessments. Compared to patients who did not use or receive treatment, the adjusted risk ratio (aRR) for attending appointments for patients who did use but did not receive treatment was 0.97 (95% confidence limits: 0.92, 1.03). The corresponding aRR for virologic suppression was 0.94 (0.86, 1.03). Compared to patients who did not receive treatment but did use, the aRR for attending appointments for patients who did receive treatment and did use was 0.86 (0.78, 0.95). The corresponding aRR for virologic suppression was 1.07 (0.92, 1.24). Use was negatively associated with attendance and virologic suppression among patients not in treatment. Among users, treatment was negatively associated with attendance yet positively associated with virologic suppression. However, aRR estimates were imprecise.

Persistent racial disparities in survival after heart transplantation

BACKGROUND

Racial and ethnic disparities are well documented in many areas of health care, but have not been comprehensively evaluated among recipients of heart transplants.

METHODS AND RESULTS

We performed a retrospective cohort study of 39075 adult primary heart transplant recipients from 1987 to 2009 using national data from the United Network of Organ Sharing and compared mortality for nonwhite and white patients using the Cox proportional hazards model. During the study period, 8082 nonwhite and 30 993 white patients underwent heart transplantation. Nonwhite heart transplant recipients increased over time, comprising nearly 30% of transplantations since 2005. Nonwhite recipients had a higher clinical risk profile than white recipients at the time of transplantation, but had significantly higher posttransplantation mortality even after adjustment for baseline risk. Among the nonwhite group, only black recipients had an increased risk of death compared with white recipients after multivariable adjustment for recipient, transplant, and socioeconomic factors (hazard ratio, 1.34; 95% confidence interval, 1.21 to 1.47; P<0.001). Five-year mortality was 35.7% (95% confidence interval, 35.2 to 38.3) among black and 26.5% (95% confidence interval, 26.0 to 27.0) among white recipients. Black patients were more likely to die of graft failure or a cardiovascular cause than white patients, but less likely to die of infection or malignancy. Although mortality decreased over time for all transplant recipients, the disparity in mortality between blacks and whites remained essentially unchanged.

CONCLUSIONS

Black heart transplant recipients have had persistently higher mortality than whites recipients over the past 2 decades, perhaps because of a higher rate of graft failure.

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.

Factors influencing the effectiveness of interventions to reduce racial and ethnic disparities in health care

Reducing racial and ethnic disparities in health care has become an important policy goal in the United States and other countries, but evidence to inform interventions to address disparities is limited. The objective of this study was to identify important dimensions of interventions to reduce health care disparities. We used qualitative research methods to examine interventions aimed at improving diabetes and/or cardiovascular care for patients from racial and ethnic minority groups within five health care organizations. We interviewed 36 key informants and conducted a thematic analysis to identify important features of these interventions. Key elements of interventions included two contextual factors (external accountability and alignment of incentives to reduce disparities) and four factors related to the organization or intervention itself (organizational commitment, population health focus, use of data to inform solutions, and a comprehensive approach to quality). Consideration of these elements could improve the design, implementation, and evaluation of future interventions to address racial and ethnic disparities in health care.

Temporal changes in the age distribution of inflammatory bowel disease hospitalization: data from England and Scotland

OBJECTIVE

The ages of patients with Crohn's disease and ulcerative colitis are characterized by a bimodal distribution. This study used separate hospital statistics from England and Scotland to follow the changes in the age distribution of inflammatory bowel disease. The objective of the analysis was to check whether the time trends of hospitalization would show different patterns among different age groups.

METHODS

Hospital statistics from England (1989-2006) and Scotland (1981-2007) were obtained through special requests to the national statistical offices. Hospitalizations (with Crohn's disease or ulcerative colitis listed as primary or primary plus secondary discharge diagnosis) were expressed as age-specific and sex-specific rates per 10 000 living population. The separate age-specific rates of Crohn's disease and ulcerative colitis of consecutive 6-year or 7-year time intervals were plotted against their respective age group.

RESULTS

The hospital data reveal a bimodal age distribution, with a more prominent first peak occurring in younger patients with Crohn's disease and a more prominent second peak occurring in older patients with ulcerative colitis. During the past two decades, the hospitalization rates for both diseases increased in all age groups. However, the increase was relatively more pronounced in the elderly, especially with ulcerative colitis. The age-shift towards older patients was also more evident for Crohn's disease or ulcerative colitis listed as secondary than primary discharge diagnosis.

CONCLUSION

The age-related shift in the occurrence of inflammatory bowel disease could reflect the impact of a birth-cohort pattern that underlies the long-term time trends of ulcerative colitis and Crohn's disease.

What's wrong with these people? clinicians' views of clinical couples

Marriage and family therapy (MFT) faculty and graduate students rated the "typical" or predictable behaviors of husbands or wives coming for therapy using the Georgia Marriage Q-sort. Scores were compared with previously published scores for both "ideal" couples (i.e., showing positive behaviors, attitudes, and problem-solving skills) and a sample of 136 nonclinical, community couples. A review of correlations between MFT raters' scores for clients and the scores for "ideal" or actual community husbands or wives indicated that clinicians have negative views of both clinical husbands and wives. Such negative views of clinical husbands and wives are particularly marked in scores by MFT faculty. MFT students had a similarly negative view of clinical husbands, but such views were not evident for clinical wives. Recommendations for MFT training and implications for future research are discussed.

Racial disparities in HIV virologic failure: do missed visits matter?

BACKGROUND

Racial/ethnic health care disparities are well described in people living with HIV/AIDS, although the processes underlying observed disparities are not well elucidated.

METHODS

A retrospective analysis nested in the University of Alabama at Birmingham 1917 Clinic Cohort observational HIV study evaluated patients between August 2004 and January 2007. Factors associated with appointment nonadherence, a proportion of missed outpatient visits, were evaluated. Next, the role of appointment nonadherence in explaining the relationship between African American race and virologic failure (plasma HIV RNA >50 copies/mL) was examined using a staged multivariable modeling approach.

RESULTS

Among 1221 participants, a broad distribution of appointment nonadherence was observed, with 40% of patients missing at least 1 in every 4 scheduled visits. The adjusted odds of appointment nonadherence were 1.85 times higher in African American patients compared with whites [95% confidence interval (CI) = 1.61 to 2.14]. Appointment nonadherence was associated with virologic failure (odds ratio = 1.78, 95% CI = 1.48 to 2.13) and partially mediated the relationship between African American race and virologic failure. African Americans had 1.56 times the adjusted odds of virologic failure (95% CI = 1.19 to 2.05), which declined to 1.30 (95% CI = 0.98 to 1.72) when controlling for appointment nonadherence, a hypothesized mediator.

CONCLUSIONS

Appointment nonadherence was more common in African American patients, associated with virologic failure, and seemed to explain part of observed racial disparities in virologic failure.

Evaluating interventions to reduce health care disparities: an RWJF program

The Robert Wood Johnson Foundation's Finding Answers: Disparities Research for Change program funds evaluation of interventions to reduce racial and ethnic disparities in cardiovascular disease, depression, and diabetes. Of the 177 applications received in 2006, the most prevalent proposed interventions were patient or provider education (57 percent), community health workers (25 percent), case management (24 percent), integrated health care (24 percent), and cultural modification (24 percent). Policy interventions, including pay-for-performance (P4P) incentives, were lacking. The eleven grantees target patients, providers, patient-provider communication, health care organizations, and communities in innovative ways. We identify important future research questions.

Use of a uniform treatment algorithm abolishes racial disparities in glycemic control

PURPOSE

The purpose of this study is to compare glycemic control between blacks and whites in a setting where patient and provider behavior is assessed, and where a uniform treatment algorithm is used to guide care.

METHODS

This observational cohort study was conducted in 3542 patients (3324 blacks, 218 whites) with type 2 diabetes with first and 1-year follow-up visits to a municipal diabetes clinic; a subset had 2-year follow-up. Patient adherence and provider management were determined. The primary endpoint was A1c.

RESULTS

At presentation, A1c was higher in blacks than whites (8.9% vs 8.3%; P < .001), even after adjusting for demographic and clinical characteristics. During 1 year of follow-up, patient adherence to scheduled visits and medications was comparable in both groups, and providers intensified medications with comparable frequency and amount. After 1 year, A1c differences decreased but remained significant (7.7% vs 7.3%; P = .029), even in multivariable analysis (P = .003). However, after 2 years, A1c differences were no longer observed by univariate (7.6% vs 7.5%; P = .51) or multi-variable analysis (P = .18).

CONCLUSIONS

Blacks have higher A1c than whites at presentation, but differences narrow after 1 year and disappear after 2 years of care in a setting where patient and provider behavior are comparable and that emphasizes uniform intensification of therapy. Presumably, racial disparities at presentation reflected prior inequalities in management. Use of uniform care algorithms nationwide should help to reduce disparities in diabetes outcomes.

Inequity of access to investigation and effect on clinical outcomes: prognostic study of coronary angiography for suspected stable angina pectoris

OBJECTIVES

To determine whether coronary angiography for suspected stable angina pectoris is underused in older patients, women, south Asian patients, and those from socioeconomically deprived areas, and, if it is, whether this is associated with higher coronary event rates.

DESIGN

Multicentre cohort with five year follow-up.

SETTING

Six ambulatory care clinics in England.

PARTICIPANTS

1375 consecutive patients in whom coronary angiography was individually rated as appropriate with the Rand consensus method.

MAIN OUTCOME MEASURES

Receipt of angiography (420 procedures); coronary mortality and acute coronary syndrome events.

RESULTS

In a multivariable analysis, angiography was less likely to be performed in patients aged over 64 compared with those aged under 50 (hazard ratio 0.60, 95% confidence interval 0.38 to 0.96), women compared with men (0.42, 0.35 to 0.50), south Asians compared with white people (0.48, 0.34 to 0.67), and patients in the most deprived fifth compared with the other four fifths (0.66, 0.40 to 1.08). Not undergoing angiography when it was deemed appropriate was associated with higher rates of coronary event.

CONCLUSIONS

At an early stage after presentation with suspected angina, coronary angiography is underused in older people, women, south Asians, and people from deprived areas. Not receiving appropriate angiography was associated with a higher risk of coronary events in all groups. Interventions based on clinical guidance that supports individualised management decisions might improve access and outcomes.

Racial disparities in cancer therapy: did the gap narrow between 1992 and 2002?

BACKGROUND

The purpose of this study was to determine whether racial disparities in cancer therapy had diminished since the time they were initially documented in the early 1990s.

METHODS

The authors identified a cohort of patients in the SEER-Medicare linked database who were ages 66 to 85 years and who had a primary diagnosis of colorectal, breast, lung, or prostate cancer during 1992 through 2002. The authors identified 7 stage-specific processes of cancer therapy by using Medicare claims. Candidate covariates in multivariate logistic regression included year, clinical, and sociodemographic characteristics, and physician access before cancer diagnosis.

RESULTS

During the full study period, black patients were significantly less likely than white patients to receive therapy for cancers of the lung (surgical resection of early stage, 64.0% vs 78.5% for blacks and whites, respectively), breast (radiation after lumpectomy, 77.8% vs 85.8%), colon (adjuvant therapy for stage III, 52.1% vs 64.1%), and prostate (definitive therapy for early stage, 72.4% vs 77.2%, respectively). For both black and white patients, there was little or no improvement in the proportion of patients receiving therapy for most cancer therapies studied, and there was no decrease in the magnitude of any of these racial disparities between 1992 and 2002. Racial disparities persisted even after restricting the analysis to patients who had physician access before their diagnosis.

CONCLUSIONS

There has been little improvement in either the overall proportion of Medicare beneficiaries receiving cancer therapies or the magnitude of racial disparity. Efforts in the last decade to mitigate cancer therapy disparities appear to have been unsuccessful.

The effect of patients' sex on physicians' recommendations for total knee arthroplasty

BACKGROUND

The underuse of total joint arthroplasty in appropriate candidates is more than 3 times greater among women than among men. When surveyed, physicians report that the patient's sex has no effect on their decision-making; however, what occurs in clinical practice may be different. The purpose of our study was to determine whether patients' sex affects physicians' decisions to refer a patient for, or to perform, total knee arthroplasty.

METHODS

Seventy-one physicians (38 family physicians and 33 orthopedic surgeons) in Ontario performed blinded assessments of 2 standardized patients (1 man and 1 woman) with moderate knee osteoarthritis who differed only by sex. The standardized patients recorded the physicians' final recommendations about total knee arthroplasty. Four surgeons did not consent to the inclusion of their data. After detecting an overall main effect, we tested for an interaction with physician type (family physician v. orthopedic surgeon). We used a binary logistic regression analysis with a generalized estimating equation approach to assess the effect of patients' sex on physicians' recommendations for total knee arthroplasty.

RESULTS

In total, 42% of physicians recommended total knee arthroplasty to the male but not the female standardized patient, and 8% of physicians recommended total knee arthroplasty to the female but not the male standardized patient (odds ratio [OR] 4.2, 95% confidence interval [CI] 2.4-7.3, p < 0.001; risk ratio [RR] 2.1, 95% CI 1.5-2.8, p < 0.001). The odds of an orthopedic surgeon recommending total knee arthroplasty to a male patient was 22 times (95% CI 6.4-76.0, p < 0.001) that for a female patient. The odds of a family physician recommending total knee arthroplasty to a male patient was 2 times (95% CI 1.04-4.71, p = 0.04) that for a female patient.

INTERPRETATION

Physicians were more likely to recommend total knee arthroplasty to a male patient than to a female patient, suggesting that gender bias may contribute to the sex-based disparity in the rates of use of total knee arthroplasty.

Ethnic disparities in diabetes care: myth or reality?

PURPOSE OF REVIEW

Ethnic disparities in disease management have been clearly documented across the medical field, but appear to be an even greater issue with regards to chronic disease. While various gaps in the provision of quality care persist, there have been some improvements in addressing some of those challenges. The purpose of this review is to highlight some of the persistent gaps in the provision of healthcare, with a focus on disparities seen in vulnerable populations, as well as opportunities to address those disparities.

RECENT FINDINGS

Disparities in the provision of health persist, especially in vulnerable populations. There is a growing awareness to actively address these issues. A number of projects have been undertaken to assess their impact on the provision of quality healthcare and consequent outcomes, with mixed results. For vulnerable populations, it appears that individualized, repeated, culturally sensitive interventions that involve the community from their inception have had the greatest positive impact.

SUMMARY

A growing body of data is emerging to not only highlight the disparities in healthcare we still confront in the USA, but to also implement strategies to successfully address and resolve those challenges.

Loss of international medical experiences: knowledge, attitudes and skills at risk

BACKGROUND

Despite the great influence International Medical Experiences (IMs) can have on young physicians and their impact on patients and communities, they are not offered in all training programs and are at risk of being reduced in some due to stringent guidelines for funding of graduate medical education.

DISCUSSION

IMs provide unique experiences in clinical, epidemiologic, cultural, and political arenas. From an educational perspective, they broaden a physician's differential diagnostic skills and introduce clinical entities rarely seen in the U.S. Time spent in developing countries emphasizes the importance of community health and increases cultural and linguistic competence. Experience working with the underserved during an IM has been shown to increase interest in volunteerism, humanitarian efforts, and work with underserved populations both in the US and abroad. IMs also afford physicians the opportunity to learn about the delivery of health care abroad and are associated with an increase in primary care specialty choice.

SUMMARY

It is time for the leaders in graduate medical education to prioritize international health opportunities. Leaders in academic medicine can press for changes in reimbursement patterns at the national level or special funds for international electives. Hospitals can set up separate accounts to help finance resident salaries and benefits while abroad. Individual departments must be flexible with resident schedules to allow elective time. Medical students and housestaff can organize and lobby larger organizations such as the American Medical Association (AMA), the American Association of Medical Colleges (AAMC), and specialty groups to make IMs universally accessible.

Racial and socioeconomic disparities in bone density testing before and after hip fracture

BACKGROUND

Racial and socioeconomic disparities have been identified in osteoporosis screening.

OBJECTIVE

To determine whether racial and socioeconomic disparities in osteoporosis screening diminish after hip fracture.

DESIGN

Retrospective cohort study of female Medicare patients.

SETTING

Entire states of Illinois, New York, and Florida.

PARTICIPANTS

Female Medicare recipients aged 65-89 years old with hip fractures between January 2001 and June 2003.

MEASUREMENTS

Differences in bone density testing by race/ethnicity and zip-code level socioeconomic characteristics during the 2-year period preceding and the 6-month period following a hip fracture.

RESULTS

Among all 35,681 women with hip fractures, 20.7% underwent bone mineral density testing in the 2 years prior to fracture and another 6.2% underwent testing in the 6 months after fracture. In a logistic regression model adjusted for age, state, and comorbidity, women of black race were about half as likely (RR 0.52 [0.43, 0.62]) and Hispanic women about 2/3 as likely (RR 0.66 [0.54, 0.80]) as white women to undergo testing before their fracture. They remained less likely (RR 0.66 [0.50, 0.88] and 0.58 [0.39, 0.87], respectively) to undergo testing after fracture. In contrast, women residing in zip codes in the lowest tertile of income and education were less likely than those in higher-income and educational tertiles to undergo testing before fracture, but were no less likely to undergo testing in the 6 months after fracture.

CONCLUSIONS

Racial, but not socioeconomic, differences in osteoporosis evaluation continued to occur even after Medicare patients had demonstrated their propensity to fracture. Future interventions may need to target racial/ethnic and socioeconomic disparities differently.

Development of a decision aid to address racial disparities in utilization of knee replacement surgery

OBJECTIVE

Previous studies suggest that poorer knowledge and expectations about surgical outcomes may be responsible for low rates of total knee replacement (TKR) among African American males. The goal of this study was to pilot test the scope, acceptability, and efficacy of an educational videotape and tailored TKR decision aid designed to reduce disparities in TKR knowledge and expectations.

METHODS

African American and Caucasian male veteran volunteers ages 55-85 years with moderate to severe knee osteoarthritis (OA) were recruited. During group meetings, patients viewed a video about knee OA treatments and were provided a personalized arthritis report that presented predicted patient outcomes should they decide to undergo TKR. Patients completed baseline and postintervention questionnaires that included an adapted Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) instrument to measure post-TKR expectations (0-100 scale with higher scores reflecting poorer outcomes).

RESULTS

A total of 102 patients (54 African American, 48 Caucasian) completed the baseline survey and 64 patients attended the intervention. There were no significant differences by race between patients completing and those dropping out of the study. At baseline (n = 102), African American patients expressed lower expectations about post-TKR outcomes than did Caucasian patients for both pain (WOMAC score 41 versus 34; P = 0.18) and physical function expectations (WOMAC score 38 versus 30; P = 0.13). Among African Americans who underwent the intervention, expected pain and physical function improved to 31 (P = 0.04 versus baseline) and 30 (P = 0.09 versus baseline), respectively. Caucasian patients' expectations changed little.

CONCLUSION

Disparities in baseline knowledge and expectations about TKR may be improved with the combined educational video and tailored decision aid.

Inégalités de santé et d'accès secondaire aux soins

The role of health care inequalities in social inequalities in health should be reconsidered since the quality of health care varies according to the social status. Some of the health care inequalities are constructed by not taking account of health inequalities in the development of programs or recommendations of medical practice and thus ending up with management procedures that do not reduce inequalities to a minimum but even contribute to increasing them. Other health care inequalities are due to omission, linked to the operating inertia of a health care system that does not recognize these inequalities and has no plan to catch them up. To reverse this situation it seems necessary to act at the three levels of the health care system: to change the clinical paradigm at the micro level, tackle the organizations issues at the meso level, and pursue the reform of the entire health care system at the macro level.

Eliminating racial and ethnic disparities in health care: what is the role of academic medicine?

Research has shown that minority Americans have poorer health outcomes (compared to whites) from preventable and treatable conditions such as cardiovascular disease, diabetes, asthma, and cancer. In addition to racial and ethnic disparities in health, there is also evidence of racial and ethnic disparities in health care. The Institute of Medicine Report Unequal Treatment remains the preeminent study of the issue of racial and ethnic disparities in health care in the United States. Unequal Treatment provided a series of general and specific recommendations to address such disparities in health care, focusing on a broad set of stakeholders including academic medicine. Academic medicine has several important roles in society, including providing primary and specialty medical services, caring for the poor and uninsured, engaging in research, and educating health professionals. Academic medicine should also provide national leadership by identifying innovations and creating solutions to the challenges our health care system faces in its attempt to deliver high-quality care to all patients. Several of the recommendations of Unequal Treatment speak directly to the mission and roles of academic medicine. For instance, patient care can be improved by collecting and reporting data on patients' race/ethnicity; education can minimize disparities by integrating cross-cultural education into health professions training; and research can help improve health outcomes by better identifying sources of disparities and promising interventions. These recommendations have clear and direct implications for academic medicine. Academic medicine must make the elimination of health care disparities a critical part of its mission, and provide national leadership by identifying quality improvement innovations and creating disparities solutions.

Postscript

In this report, we compare healthcare processes for patients with low (n = 7467) and adequate financial status (n = 43,701) after adjustment for age, gender, burden of illness, and health behaviors. Patients with low financial status were 10% to 30% less likely to report good service and collaborative care; they report that markers of disease management and prevention were 7% to 18% below the levels of patients with adequate income. From the patient perspective, these results confirm that inadequate financial status has a broad and adverse influence on health and healthcare. Technology for patient-centered, collaborative care alone will not remedy the problem of health disparity.

Current issues in joint replacement surgery

PURPOSE OF REVIEW

Joint replacement surgery continues to grow in sheer number of procedures and quantity of research. We wish to highlight the key findings in the literature about variations in utilization, timing of procedure, outcomes, and minimally invasive techniques.

RECENT FINDINGS

Several studies reinforce the improved pain and function after joint replacement surgery. The best predictor of postoperative pain and function appears to be preoperative pain and function, respectively. In one study, authors expressed concern that patients may be systematically reporting better outcomes than they truly achieve. In spite of the generally favorable results after surgery, there remains considerable geographic, racial, and gender variation in utilization. The optimal timing for surgery is unknown but may be influenced by the advent of the newer longer-lasting prosthesis. Patients with poorer preoperative function tend to have poorer outcomes, regardless of baseline pain or function. Evidence thus far has demonstrated similar outcomes between minimal and standard incisions for hip arthroplasty.

SUMMARY

Advances in our understanding of outcomes after joint replacement aid in predicting best candidates for surgery. More study is needed on the optimal timing of replacement surgery and the variations in utilization.

Cancer incidence in Montana: rates for American Indians exceed those for whites

OBJECTIVES

Previous studies suggested that the cancer incidence rates in American Indians and Alaska Natives were lower than in other groups. The objective of this study was to compare the cancer incidence rates in American Indians and whites in Montana.

METHODS

Age-adjusted 6-year cancer incidence rates were calculated for American-Indian and white men and women in Montana to allow comparison of rates in 1991-1996 to those in 1997-2002.

RESULTS

The age-adjusted rates for American-Indian men were significantly higher than those for white men for all cancer sites (755+/-74 [95% confidence interval] per 100,000 vs 544+/-9 per 100,000), lung cancer (167+/-35 per 100,000 vs 83+/-4 per 100,000), and colorectal cancer (115+/-29 per 100,000 vs 61+/-4 per 100,000) from 1997 to 2002. The adjusted rates for American-Indian women were significantly higher than those for white women for all cancer sites (526+/-47 per 100,000 vs 412+/-8 per 100,000) and lung cancer (120+/-24 per 100,000 vs 56+/-3 per 100,000) during this same time period. There was a significant increase in the age-adjusted rates for all cancer sites among white men and women but not for American-Indian men or women between 1991-1996 and 1997-2002.

CONCLUSIONS

There is a significant disparity in the cancer incidence rates between American Indians and whites in Montana. Regional or state-level surveillance data will be needed to describe the changing patterns of cancer incidence in many native communities in the United States.

Emerging and widening colorectal carcinoma disparities between Blacks and Whites in the United States (1975-2002)

BACKGROUND

Colorectal carcinoma (CRC) is the fourth most common cancer diagnosed and the second most common cause of cancer death in the U.S. Incidence and mortality rates have decreased since the mid-1980s, although more among Whites than Blacks.

METHODS

To determine if these racial differences were changing over time, we examined CRC rates in the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program (1975-2002). Rates were stratified by gender, race, anatomic subsite, historic stage, and grade.

RESULTS

CRC rates were higher among men than women and higher among Blacks than Whites, with Black men having the highest rates during the latter years. Prior to the mid-1980s, male CRC rates were actually higher among Whites than Blacks; after which there was ethnic crossover with Black rates higher than White rates, and the gaps are widening. Proximal and transverse CRCs were more common and rectal cancers were less common among Blacks than Whites. Over time, rates for localized and regional stages increased among Blacks and decreased among Whites. Rates for distant stages declined for both racial groups, although less among Blacks. Black-to-White rate ratio for distant stage was approximately 1.30. Notably, Blacks compared with Whites had lower grade tumors, despite higher stages and mortality rates.

CONCLUSIONS

CRC racial disparities have emerged and widened for three decades. These temporal trends probably reflect complicated racial differences between screening practice patterns and etiologic factors.

Legal constraints on the use of race in biomedical research: toward a social justice framework

This article addresses three questions concerning the legal regulation of the use of race as a category in biomedical research: how does the law currently encourage the use of race in biomedical research?; how might the existing legal framework constrain its use?; and what should be the law's approach to race-based biomedical research? It proposes a social justice approach that aims to promote racial equality by discouraging the use of "race" as a biological category while encouraging its use as a socio-political category to understand and investigate ways to eliminate disparities in health status, access to health care, and medical treatment.

Legal regulation of the use of race in medical research

In this article, we discuss current legal restrictions governing the use of race in medical research. In particular, we focus on whether the use of race in various types of research is presently permitted under federal law and the federal constitution. We also discuss whether federal restrictions on the use of race in research ought to be expanded, and whether federal policies that encourage the use of race ought to be abandoned.
