Primary-care clinician perceptions of racial disparities in diabetes care

Health Professionals' Perceptions of Disparities in Hypertension Control: A Mixed Methods Study

BACKGROUND

Health professionals' commitment is needed to address disparities in hypertension control by ancestry, but their perceptions regarding these disparities are understudied.

METHODS

Cross-sectional mixed methods study in a universal healthcare setting in the Netherlands. Snowball sampling was used to include professionals practicing in a large multicity conglomerate including the capital city. Online surveys were collected, and survey participants were randomly selected for in-depth interviews. We used quantitative and qualitative methods to analyze health professionals' awareness, beliefs, and possible interventions regarding these disparities.

RESULTS

We analyzed questionnaire data of 77 health professionals (medical doctors n = 70, nurses = 7), whereas 13 were interviewed. Most professionals were women (59%), general practitioners (81%); and White-European (77%), with 79% caring for patients of diverse ancestry. Disparities in hypertension control by ancestry were perceived to exist nationally (83% [95% CI, 75;91]), but less so in health professionals' own clinics (62% [52;73]), or among their own patients (56% [45;67]). Survey respondents emphasized patient rather than provider-level factors as mediators of poor hypertension control by ancestry. The collection of data on patients' ancestry, updating guidelines, and professional training were considered helpful to reduce disparities. Interviewees further emphasized patient-level factors, but also the need to better educate health professionals and increase their awareness.

CONCLUSIONS

This explorative study finds that health professionals predominantly attribute disparities in hypertension control to patient-level factors. Awareness of disparities was lower for more proximate healthcare settings. These data emphasize the need to consider health professionals' perceptions when addressing disparities in hypertension control.

Encountering the social determinants of health on a COVID-19 ICU: Frontline providers' perspectives on inequality in a time of pandemic

Efforts to improve health equity may be advanced by understanding health care providers' perceptions of the causes of health inequalities. Drawing on data from in-depth interviews with nurses and registered respiratory therapists (RRTs) who served on intensive care units (ICUs) during the first surge of the pandemic, this paper examines how frontline providers perceive and attribute the unequal impacts of COVID-19. It shows that nurses and RRTs quickly perceived the pandemic's disproportionate burden on Black and Latinx individuals and families. Providers attribute these inequalities to the social determinants of health, and also raise questions about how barriers to healthcare access may have made some patients more vulnerable to the worst consequences of COVID-19. Providers' perceptions of inequality and its consequences on COVID-19 ICUs were emotionally impactful and distressing, suggesting that this is a critical moment for offering clinicians practical strategies for understanding and addressing the persistent structural inequities that cause racial inequalities in health.

Veterans Affairs Providers' Beliefs About the Contributors to and Responsibility for Reducing Racial and Ethnic Health Care Disparities

Purpose: Providers' beliefs about the causes of disparities and the entities responsible for addressing these disparities are important in designing disparity-reduction interventions aimed at providers. This secondary analysis of a larger study is aimed at evaluating perceptions of providers regarding the underlying causes of racial health care disparities and their views of who is responsible for reducing them. Methods: We surveyed 232 providers at 3 Veterans Affairs (VA) Medical Centers. Results: Sixty-nine percent of participants believed that minority patients in the United States receive lower quality health care. Most participants (64%) attributed differences in quality of care for minority patients in the VA health care system primarily to patients' socioeconomic status, followed by patient behavior (43%) and provider behaviors (33%). In contrast, most participants believed that the VA and other health care organizations (75%) and providers (70%) bear the responsibility for reducing disparities, while less than half (45%) believed that patients were responsible. Among provider-level contributors to disparities, providers' poor communication was the most widely endorsed (48%), while differences in prescribing of medications (13%) and in provision of specialty referrals (12%) were the least endorsed. Conclusions: Although most providers in the study did not believe that providers contribute to disparities, they do believe that they, along with health care organizations, have the responsibility to help reduce them. Interventions might focus on directly offering providers concrete ways that they can help reduce disparities, rather than focusing on simply raising awareness about disparities and their contributions to them.

Awareness of Racial Disparities in Diabetes Among Primary Care Residents and Preparedness to Discuss Disparities with Patients

Many healthcare providers lack the awareness of health disparities among their patients that precedes action to improve outcomes. Limited health disparities training is a probable contributor. We assessed primary care residents' awareness of racial and ethnic disparities in diabetes, their perceived preparedness to discuss health disparities with patients, and their preferences for training and resources to improve their preparedness. Primary care residents (n = 98) affiliated with two teaching hospitals in North Carolina were invited to complete a 20-question health disparities survey. Fifty-two residents completed the survey (response rate = 53%). Most were non-Hispanic White (54%) and had ≤ 50% African American patients in their panel (65%). Although 83% were aware of higher diabetes prevalence among African Americans, only 31% felt prepared to discuss diabetes health disparities with patients. Their primary concerns included not having information for the discussion (58%) and being unsure how to share information in a way that is easy for patients to understand (48%). Perceived preparedness to discuss health disparities did not differ significantly by primary care resident race or percentage of African American patients in their panel. Residents indicated that having information regarding how to discuss and address health disparities would make them feel more prepared. Cultural competency training and experiential learning were the most preferred methods to learn how to identify and address health disparities. Future health disparities training should focus on improving residents' preparedness to address health disparities in their clinical practice using culturally relevant communication tools and experiential learning opportunities.

What Causes Racial Health Care Disparities? A Mixed-Methods Study Reveals Variability in How Health Care Providers Perceive Causal Attributions

Progress to address health care equity requires health care providers’ commitment, but their engagement may depend on their perceptions of the factors contributing to inequity. To understand providers’ perceptions of causes of racial health care disparities, a short survey was delivered to health care providers who work at 3 Veterans Health Administration sites, followed by qualitative interviews (N = 53). Survey data indicated that providers attributed the causes of disparities to social and economic conditions more than to patients’ or providers’ behaviors. Qualitative analysis revealed differences in the meaning that participants ascribed to these causal factors. Participants who believed providers contribute to disparities discussed race and racism more readily, identified the mechanisms through which disparities emerge, and contextualized patient-level factors more than those who believed providers contributed less to disparities. Differences in provider understanding of the underlying causal factors suggest a multidimensional approach to engage providers in health equity efforts.

Healthcare Providers' Responses to Narrative Communication About Racial Healthcare Disparities

We used qualitative methods (semi-structured interviews with healthcare providers) to explore: 1) the role of narratives as a vehicle for raising awareness and engaging providers about the issue of healthcare disparities and 2) the extent to which different ways of framing issues of race within narratives might lead to message acceptance for providers' whose preexisting beliefs about causal attributions might predispose them to resist communication about racial healthcare disparities. Individual interviews were conducted with 53 providers who had completed a prior survey assessing beliefs about disparities. Participants were stratified by the degree to which they believed providers contributed to healthcare inequality: low provider attribution (LPA) versus high provider attribution (HPA). Each participant read and discussed two differently framed narratives about race in healthcare. All participants accepted the "Provider Success" narratives, in which interpersonal barriers involving a patient of color were successfully resolved by the provider narrator, through patient-centered communication. By contrast, "Persistent Racism" narratives, in which problems faced by the patient of color were more explicitly linked to racism and remained unresolved, were very polarizing, eliciting acceptance from HPA participants and resistance from LPA participants. This study provides a foundation for and raises questions about how to develop effective narrative communication strategies to engage providers in efforts to reduce healthcare disparities.

Communicating with providers about racial healthcare disparities: The role of providers' prior beliefs on their receptivity to different narrative frames

OBJECTIVE

Evaluate narratives aimed at motivating providers with different pre-existing beliefs to address racial healthcare disparities.

METHODS

Survey experiment with 280 providers. Providers were classified as high or low in attributing disparities to providers (HPA versus LPA) and were randomly assigned to a non-narrative control or 1 of 2 narratives: "Provider Success" (provider successfully resolved problem involving Black patient) and "Provider Bias" (Black patient experienced racial bias, which remained unresolved). Participants' reactions to narratives (including identification with narrative) and likelihood of participating in disparities-reduction activities were immediately assessed. Four weeks later, participation in those activities was assessed, including self-reported participation in a disparities-reduction training course (primary outcome).

RESULTS

Participation in training was higher among providers randomized to the Provider Success narrative compared to Provider Bias or Control. LPA participants had higher identification with Provider Success than Provider Bias narratives, whereas among HPA participants, differences in identification between the narratives were not significant.

CONCLUSIONS

Provider Success narratives led to greater participation in training than Provider Bias narratives, although providers' pre-existing beliefs influenced the narrative they identified with.

PRACTICE IMPLICATIONS

Provider Success narratives may be more effective at motivating providers to address disparities than Provider Bias narratives, though more research is needed.

Ensnared by Colorblindness: Discourse on Health Care Disparities

Objective

Race consciousness serves as the foundation for Critical Race Theory (CRT) methodology. Colorblindness minimizes racism as a determinant of outcomes. To achieve the emancipatory intent of CRT and to reduce health care disparities, we must understand: 1) how colorblindness "shows up" when health care professionals aim to promote equity; 2) how their colorblindness informs (and is informed by) clinical practice; and 3) ways to overcome colorblindness through strategies grounded in CRT.

Design/Setting/Participants

We conducted 21 semi-structured interviews with key informants and seven focus groups with personnel employed by a large Minnesota health care system. We coded transcripts inductively and deductively for themes using the constant comparative method. We used a race-conscious approach to examine how respondents' accounts align or diverge from colorblindness.

Results

Evading race, respondents considered socioeconomic status, cultural differences, and patients' choices to be the main contributors to health disparities. Few criticized the behavior of coworkers or that of the organization or acknowledged structural racism. Respondents strongly believed that all patients were treated equally by providers and staff, in part due to race-neutral care processes and guidelines. Respondents also used several semantic moves common to colorblindness to refute suggestions of racial inequality.

Conclusions

Colorblindness upholds the racial status quo and inhibits efforts to promote health equity. Drawing on CRT to guide them, health care leaders will need to develop strategies to counter personnel's tendency to focus on axes of inequality other than race, to decontextualize patients' health behaviors and choices, and to depend heavily on race-neutral care processes to produce equitable outcomes.

Awareness of Racial Disparities in Kidney Transplantation among Health Care Providers in Dialysis Facilities

BACKGROUND AND OBJECTIVES

Despite the important role that health care providers at dialysis facilities have in reducing racial disparities in access to kidney transplantation in the United States, little is known about provider awareness of these disparities. We aimed to evaluate health care providers' awareness of racial disparities in kidney transplant waitlisting and identify factors associated with awareness.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We conducted a cross-sectional analysis of a survey of providers from low-waitlisting dialysis facilities (n=655) across all 18 ESRD networks administered in 2016 in the United States merged with 2014 US Renal Data System and 2014 US Census data. Awareness of national racial disparity in waitlisting was defined as responding "yes" to the question: "Nationally, do you think that African Americans currently have lower waitlisting rates than white patients on average?" The secondary outcome was providers' perceptions of racial difference in waitlisting at their own facilities.

RESULTS

Among 655 providers surveyed, 19% were aware of the national racial disparity in waitlisting: 50% (57 of 113) of medical directors, 11% (35 of 327) of nurse managers, and 16% (35 of 215) of other providers. In analyses adjusted for provider and facility characteristics, nurse managers (versus medical directors; odds ratio, 7.33; 95% confidence interval, 3.35 to 16.0) and white providers (versus black providers; odds ratio, 2.64; 95% confidence interval, 1.39 to 5.02) were more likely to be unaware of a national racial disparity in waitlisting. Facilities in the South (versus the Northeast; odds ratio, 3.05; 95% confidence interval, 1.04 to 8.94) and facilities with a low percentage of blacks (versus a high percentage of blacks; odds ratio, 1.86; 95% confidence interval, 1.02 to 3.39) were more likely to be unaware. One quarter of facilities had >5% racial difference in waitlisting within their own facilities, but only 5% were aware of the disparity.

CONCLUSIONS

Among a limited sample of dialysis facilities with low waitlisting, provider awareness of racial disparities in kidney transplant waitlisting was low, particularly among staff who may have more routine contact with patients.

Using a structural competency framework to teach structural racism in pre-health education

The inclusion of structural competency training in pre-health undergraduate programs may offer significant benefits to future healthcare professionals. This paper presents the results of a comparative study of an interdisciplinary pre-health curriculum based in structural competency with a traditional premedical curriculum. The authors describe the interdisciplinary pre-health curriculum, titled Medicine, Health, and Society (MHS) at Vanderbilt University. The authors then use a new survey tool, the Structural Foundations of Health Survey, to evaluate structural skills and sensibilities. The analysis compares MHS majors (n = 185) with premed science majors (n = 63) and first-semester freshmen (n = 91), with particular attention to understanding how structural factors shape health. Research was conducted from August 2015 to December 2016. Results suggest that MHS majors identified and analyzed relationships between structural factors and health outcomes at higher rates and in deeper ways than did premed science majors and freshmen, and also demonstrated higher understanding of structural and implicit racism and health disparities. The skills that MHS students exhibited represent proficiencies increasingly stressed by the MCAT, the AAMC, and other educational bodies that emphasize how contextual factors shape expressions of health and illness.

Primary Care Providers Perceptions of Racial/Ethnic and Socioeconomic Disparities in Hypertension Control

OBJECTIVE

To evaluate the attitudes and perceptions of primary care providers (PCPs) regarding the presence and underlying sources of racial/ethnic and socioeconomic disparities in hypertension control.

METHODS

We conducted a survey of 115 PCPs from 2 large academic centers in Colorado. We included physicians, nurse practitioners, and physician assistants. The survey assessed provider recognition and perceived contributors of disparities in hypertension control.

RESULTS

Respondents were primarily female (66%), non-Hispanic White (84%), and physicians (80%). Among respondents, 67% and 73% supported the collection of data on the patients' race/ethnicity and socioeconomic status (SES), respectively. Eighty-six percent and 89% agreed that disparities in race/ethnicity and SES existed in hypertension care within the US health system. However, only 33% and 44% thought racial/ethnic and socioeconomic disparities existed in the care of their own patients. Providers were more likely to perceive patient factors rather than provider or health system factors as mediators of disparities. However, most supported interventions such as improving provider communication skills (87%) and cultural competency training (89%) to reduce disparities in hypertension control.

CONCLUSIONS

Most providers acknowledged that racial/ethnic and socioeconomic disparities in hypertension control exist in the US health system, but only a minority reported disparities in care among patients they personally treat. Our study highlights the need for testing an intervention aimed at increasing provider awareness of disparities within the local health setting to improve hypertension control for minority patients.

Implicit bias and its relation to health disparities: a teaching program and survey of medical students

BACKGROUND

The varying treatment of different patients by the same physician are referred to as within provider disparities. These differences can contribute to health disparities and are thought to be the result of implicit bias due to unintentional, unconscious assumptions.

PURPOSES

The purpose is to describe an educational intervention addressing both health disparities and physician implicit bias and the results of a subsequent survey exploring medical students' attitudes and beliefs toward subconscious bias and health disparities.

METHODS

A single session within a larger required course was devoted to health disparities and the physician's potential to contribute to health disparities through implicit bias. Following the session the students were anonymously surveyed on their Implicit Association Test (IAT) results, their attitudes and experiences regarding the fairness of the health care system, and the potential impact of their own implicit bias. The students were categorized based on whether they disagreed ("deniers") or agreed ("accepters") with the statement "Unconscious bias might affect some of my clinical decisions or behaviors." Data analysis focused specifically on factors associated with this perspective.

RESULTS

The survey response rate was at least 69%. Of the responders, 22% were "deniers" and 77% were "accepters." Demographics between the two groups were not significantly different. Deniers were significantly more likely than accepters to report IAT results with implicit preferences toward self, to believe the IAT is invalid, and to believe that doctors and the health system provide equal care to all and were less likely to report having directly observed inequitable care.

CONCLUSIONS

The recognition of bias cannot be taught in a single session. Our experience supports the value of teaching medical students to recognize their own implicit biases and develop skills to overcome them in each patient encounter, and in making this instruction part of the compulsory, longitudinal undergraduate medical curriculum.

Differences in beliefs about the causes of health disparities in Black and White nurses

PURPOSE

To determine whether Black and White nurses' beliefs about causes of health disparities differ.

CONCLUSIONS

Analyses reveal that overall Black nurses perceived external factors to contribute significantly more to health disparities than White nurses. Black nurses considered four specific causes dealing with physician and societal factors, such as "discrimination in society," to be more significant contributors to health disparities than White nurses, whereas White nurses considered genetic factors to be a greater contributor.

PRACTICE IMPLICATIONS

Different views of the causes of health disparities are discussed, particularly in light of cultural competency training and other efforts to ameliorate health disparities.

Exploring the impact of language services on utilization and clinical outcomes for diabetics

Background

Significant health disparities exist between limited English proficient and English-proficient patients. Little is known about the impact of language services on chronic disease outcomes such as for diabetes.

Methods/Principal Findings

To determine whether the amount and type of language services received during primary care visits had an impact on diabetes-related outcomes (hospitalization, emergency room utilization, glycemic control) in limited English proficient patients, a retrospective cohort design was utilized. Hospital and medical record data was examined for 1425 limited English proficient patients in the Cambridge Health Alliance diabetes registry. We categorized patients receiving usual care into 7 groups based on the amount and combination of language services (language concordant providers, formal interpretation and nothing) received at primary care visits during a 9 month period. Bivariate analyses and multiple logistic regression were used to determine relationships between language service categories and outcomes in the subsequent 6 months. Thirty-one percent of patients (445) had no documentation of interpreter use or seeing a language concordant provider in any visits. Patients who received 100% of their primary care visits with language concordant providers were least likely to have diabetes-related emergency department visits compared to other groups (p<0001) in the following 6 months. Patients with higher numbers of co-morbidities were more likely to receive formal interpretation.

Conclusions/Significance

Language concordant providers may help reduce health care utilization for limited English proficient patients with diabetes. However, given the lack of such providers in sufficient numbers to meet patients' communication needs, strategies are needed to both increase their numbers and ensure that the highest risk patients receive the most appropriate language services. In addition, systems serving diverse populations must clarify why some limited English proficient patients do not receive language services at some or all of their visits and whether this has an impact on quality of care.

Clinicians' views of an intervention to reduce racial disparities in diabetes outcomes

RATIONALE

Interventions that improve clinicians' awareness of racial disparities and improve their communication skills are considered promising strategies for reducing disparities in health care. We report clinicians' views of an intervention involving cultural competency training and race-stratified performance reports designed to reduce racial disparities in diabetes outcomes.

RESEARCH DESIGN AND METHODS

Semistructured interviews were conducted with 12 physicians and 5 nurse practitioners who recently participated in a randomized intervention to reduce racial disparities in diabetes outcomes. Clinicians were asked open-ended questions about their attitudes towards the intervention, the causes of disparities, and potential solutions to them.

RESULTS

Thematic analysis of the interviews showed that most clinicians acknowledged the presence of racial disparities in diabetes control among their patients. They described a complex set of causes, including socioeconomic factors, but perceived only some causes to be within their power to change, such as switching patients to less-expensive generic drugs. The performance reports and training were generally well received but some clinicians did not feel empowered to act on the information. All clinicians identified additional services that would help them address disparities; for example, culturally tailored nutrition advice. Some clinicians challenged the premise of the intervention, focusing instead on socioeconomic factors as the primary cause of disparities rather than on patients' race.

CONCLUSIONS

The cultural competency training and performance reports were well received by many but not all of the clinicians. Clinicians reported the intervention alone had not empowered them to address the complex, root causes of racial disparities in diabetes outcomes.

Disparities in diabetes care: role of the patient's socio-demographic characteristics

Background

The commitment to promoting equity in health is derived from the notion that all human beings have the right to the best attainable health. However, disparities in health care are well-documented. The objectives were to explore disparities in diabetes prevalence, care and control among diabetic patients. The study was conducted by Maccabi Healthcare Services (MHS), an Israeli HMO (health care plan).

Methods

Retrospective study. The dependent variables were diabetes prevalence, uptake of follow-up examinations, and disease control. The independent variables were socio-economic rank (SER), ethnicity (Arab vs non Arab), supplementary voluntary health insurance (SVHI), and immigration from Former Soviet Union (FSU) countries. Chi Square and Logistic Regression Models were estimated.

Results

We analyzed 74,953 diabetes patients. Diabetes was more prevalent in males, lower SER patients, Arabs, immigrants and owners of SVHI. Optimal follow up was more frequent among females, lower SERs patients, non Arabs, immigrants and SVHI owners. Patients who were female, had higher SERs, non Arabs, immigrants and SVHI owners achieved better control of the disease. The multivariate analysis revealed significant associations between optimal follow up and age, gender (males), SER (Ranks 1-10), Arabs and SVHI (OR 1.02, 0.95, 1.15, 0.85 and 1.31, respectively); poor diabetes control (HbA1C > 9 gr%) was significantly associated with age, gender (males), Arabs, immigrants, SER (Ranks1-10) and SVHI (OR 0.96, 1.26, 1.38, 0.72, 1.37 and 0.57, respectively); significant associations with LDL control (< 100 gr%) were revealed for age, gender (males) and SVHI (OR 1.02, 1.30 and 1.44, respectively).

Conclusion

Disparities in diabetes prevalence, care and control were revealed according to population sub-group. MHS has recently established a comprehensive strategy and action plan, aimed to reduce disparities among members of low socioeconomic rank and Arab ethnicity, sub-groups identified in our study as being at risk for less favorable health outcomes.

Barriers to collecting patient race, ethnicity, and primary language data in physician practices: an exploratory study

BACKGROUND

Experts recommend that physician practices collect and use patient race, ethnicity, and primary language data to document and address health care disparities and improve health care quality for diverse populations. Little is known about demographic data collection in small practice settings.

OBJECTIVE

To conduct an exploratory study to examine demographic data collection in physician practices to reduce disparities and provide qualitative descriptions of facilitators and barriers to data collection.

DESIGN

Semistructured telephone interviews.

SETTING

Medical practices with 5 or fewer physicians.

PARTICIPANTS

Practice managers, nurse managers, and physicians from 20 practices nationwide.

RESULTS

Of the 20 practices interviewed, 9 reported collecting demographic data. Only 1 practice feature facilitated demographic data collection: use of an electronic medical record (EMR) system (7 of 10 practices with an EMR collected data). Participation in pay-for-performance programs, cultural competency training, and measuring clinical quality did not facilitate data collection. One practice linked demographic and quality data. A few used the data to track language service needs. The main perceived barriers to demographic data collection included concerns about privacy, the legality of collecting the information, possible resistance from patients and staff, difficulty recording the data, and uncertainty about whether the data would be useful.

CONCLUSIONS

Few small practices use data to track or address disparities in health care. Most perceived barriers to data collection can be surmounted. There is hope for improved collection and use of data through the spread of information technology with comprehensive national health reform.

A randomized experiment of issue framing and voter support of tax increases for health insurance expansion

OBJECTIVE

To assess the effect of issue framing on voter support of tax increases for health insurance expansion.

METHODS

During October 2008, a random sample of registered voters (n=1203) were randomized to a control and two different 'framing' groups prior to being asked about their support for tax increases. The 'framing' groups listened to one of two statements: one emphasized the externalities or negative effects of the uninsured on the insured, and the other raised racial and ethnic disparities in health insurance coverage as a problem. All groups were asked the same questions: would they support tax increases to provide adequate and reliable health insurance for three groups, (1) all American citizens, (2) all children, irrespective of citizenship, and (3) all military veterans.

RESULTS

Support for tax increases varied substantially depending on which group benefited from the expansion. Consensus on coverage for military veterans was highest (83.3%), followed by all children, irrespective of citizenship (64.7%), and all American citizens (60.1%). There was no statistically significant difference between voter support in the 'framing' and control groups or between the two frames. In multivariable analyses, political party affiliation was the strongest predictor of support.

CONCLUSIONS

Voters agree on the need for coverage of military veterans, but are less united on the coverage of all children and American citizens. Framing was less important than party affiliation, suggesting that voters consider coverage expansions and related tax increases in terms of the characteristics of the targeted group, and their own personal political views and values rather than the broader impact of maintaining the status quo.

Community-based teaching about health disparities: combining education, scholarship, and community service

The Institute of Medicine recommends that clinicians receive training to better understand and address disparities. While disparities in health status are primarily due to inequities in social determinants of health, current curricula largely focus on how to teach about disparities within the health care setting. Learners may more fully understand and appreciate how social contextual factors contribute to disparities through instruction about disparities in community settings. Community-based teaching about health disparities may be advantageous for learners, medical institutions, and participating communities. This manuscript aims to guide medical educators in teaching students and residents about health disparities through community-based activities, including service learning and research.

Health Care Disparities and Diabetes Care: Practical Considerations for Primary Care Providers

Disparities in diabetes care are prevalent in the United States. This article provides an overview of these disparities and discusses both potential causes and efforts to address them to date. The authors focus the discussion on aspects relevant to the patient-provider dyad and provide practical considerations for the primary care provider's role in helping to diminish and eliminate disparities in diabetes care.

Framing disparities along the continuum of care from chronic kidney disease to transplantation: barriers and interventions

Research in renal transplantation continues to document scores of disparities affecting vulnerable populations at various stages along the transplantation process. Given that both biological and environmental determinants contribute significantly to variation, identifying factors underlying an unfairly biased distribution of the disease burden is crucial. Confounded definitions and gaps in understanding causal pathways impede effectiveness of interventions aimed at alleviating disparities. This article offers an operational definition of disparities in the context of a framework aimed at facilitating interventional research. Utilizing an original framework describing the entire continuum of the transplant process from diagnosis of chronic kidney disease through successful transplant, this article explores the case of racial disparities, illustrating key factors predicting and perpetuating disparities. Though gaps in current research leave us unable to identify which stages of the transplant pathway adversely affect most people, by identifying key risk factors across the continuum of care, this article highlights areas suited for targeted interventions and presents recommendations for improvement and future research.

Moving upstream: how interventions that address the social determinants of health can improve health and reduce disparities

There is considerable scientific and policy interest in reducing socioeconomic and racial/ethnic disparities in healthcare and health status. Currently, much of the policy focus around reducing health disparities has been geared toward improving access, coverage, quality, and the intensity of healthcare. However, health is more a function of lifestyles linked to living and working conditions than of healthcare. Accordingly, effective efforts to improve health and reduce gaps in health need to pay greater attention to addressing the social determinants of health within and outside of the healthcare system. This article highlights research evidence documenting that tackling the social determinants of health can lead to reductions in health disparities. It focuses both on interventions within the healthcare system that address some of the social determinants of health and on interventions in upstream factors such as housing, neighborhood conditions, and increased socioeconomic status that can lead to improvements in health. The studies reviewed highlight the importance of systematic evaluation of social and economic policies that might have health consequences and the need for policy makers, healthcare providers, and leaders across multiple sectors of society to apply currently available knowledge to improve the underlying conditions that impact the health of populations.
