Improving health care quality for racial/ethnic minorities: a systematic review of the best evidence regarding provider and organization interventions

Gastrointestinal malignancies: when does race matter?

BACKGROUND

African Americans have a poorer survival from gastrointestinal cancers. We hypothesized that socioeconomic status may explain much of this disparity.

STUDY DESIGN

Four years of population-based Medicare and Medicaid administrative claims files were merged with the Michigan Tumor Registry. Data were identified for 18,260 patients with colorectal (n = 13,001), pancreatic (n = 2,427), gastric (n = 1,739), and esophageal (n = 1,093) cancer. Three outcomes were studied: the likelihood of late stage diagnosis, the likelihood of surgery after diagnosis, and survival. Bivariate analysis was used to compare stage and operation between African-American and Caucasian patients. Cox proportional hazard models were used to evaluate differences in survival. Statistical significance was defined as p < 0.05.

RESULTS

In unadjusted analyses, relative to Caucasian patients, African-American patients with colorectal and esophageal cancer were more likely to present with metastatic disease, were less likely to have surgery, and were less likely to survive during the study period (p < 0.05). In a multivariate analysis, African-American patients had a higher likelihood of death from colorectal cancer than Caucasian patients. This difference, however, did not persist when late stage and surgery were taken into account (hazard ratio = 1.15, 95% CI = 1.06 to 1.24). No racial differences in survival were observed among patients with esophagus, gastric, or pancreatic cancer.

CONCLUSIONS

These data suggest that improvements in screening and rates of operation may reduce differences in colorectal cancer outcomes between African-American and Caucasian patients. But race has little influence on survival of patients with pancreatic, esophageal, or gastric cancer.

A cluster-randomized controlled trial evaluating the effect of culturally-appropriate hypertension education among Afro-Surinamese and Ghanaian patients in Dutch general practice: study protocol

Background

Individuals of African descent living in western countries have increased rates of hypertension and hypertension-related complications. Poor adherence to hypertension treatment (medication and lifestyle changes) has been identified as one of the most important modifiable causes for the observed disparities in hypertension related complications, with patient education being recommended to improve adherence. Despite evidence that culturally-appropriate patient education may improve the overall quality of care for ethnic minority patients, few studies have focused on how hypertensive individuals of African descent respond to this approach. This paper describes the design of a study that compares the effectiveness of culturally-appropriate hypertension education with that of the standard approach among Surinamese and Ghanaian hypertensive patients with an elevated blood pressure in Dutch primary care practices.

Methods/Design

A cluster-randomized controlled trial will be conducted in four primary care practices in Amsterdam, all offering hypertension care according to Dutch clinical guidelines. After randomization, patients in the usual care sites (n = 2) will receive standard hypertension education. Patients in the intervention sites (n = 2) will receive three culturally-appropriate hypertension education sessions, culturally-specific educational materials and targeted lifestyle support. The primary outcome will be the proportion of patients with a reduction in systolic blood pressure ≥ 10 mmHg at eight months after the start of the trial. The secondary outcomes will be the proportion of patients with self-reported adherence to (i) medication and (ii) lifestyle recommendations at eight months after the start of the trial. The study will enrol 148 patients (74 per condition, 37 per site). Eligibility criteria for patients of either sex will be: current diagnosis of hypertension, self-identified Afro-Surinamese or Ghanaian, ≥ 20 years, and baseline blood pressure ≥ 140/90 mmHg. Primary and secondary outcomes will be measured at baseline and at 3 1/2, 6 1/2, and eight months. Other measurements will be performed at baseline and eight months.

Discussion

The findings will provide new knowledge on how to improve blood pressure control and patient adherence in ethnic minority persons with a high risk of negative hypertension-related health outcomes.

Preferences among immigrant Hispanic women for written educational materials regarding upper respiratory infections

The need for culturally appropriate health education materials for Hispanic populations has been widely recognized, and Spanish-language materials are available through a number of private and governmental organizations. We convened two focus groups to elucidate preferences regarding how health-related messages are obtained and to identify which educational materials available in Spanish were preferred by 26 recently immigrated Hispanic homemakers who had received 15 different bimonthly written documents as part of a community-based clinical trial to prevent household transmission of colds and influenza. Participants gave three primary reasons for volunteering to participate in the study: to provide better care for their children (96.2%, 25/26), to get information (96.2%, 25/26), and to get free products (47.1%, 8/17). Their primary sources of health-related information were relatives and friends (42.9%, 6/14), clinicians (35.7%, 5/14), mass media (14.3%, 2/14) or the emergency room (7.1%, 1/14); none mentioned the internet. Materials using either a question and answer or true/false format were clearly preferred, even when other options were more colorful or had lower reading levels. Printed educational materials may be ineffective unless they include a more systematic assessment of the user's perceived needs for the information as well as consideration of format. In this population, a question and answer or true/false format and materials that could be shared with their children were greatly preferred.

Perceptions of breast cancer treatment among African-American women and men: implications for interventions

BACKGROUND

While breast cancer mortality has declined in recent years, the mortality gap between African-American and white women continues to grow. Current strategies to reduce this disparity focus on logistical and information needs, but contextual factors, such as concerns about racism and treatment side effects, may also represent significant barriers to improved outcomes.

OBJECTIVE

To characterize perceptions of breast cancer treatment among African-American women and men.

DESIGN

A qualitative study of African-American adults using focus group interviews.

PARTICIPANTS

Two hundred eighty women and 165 men who live in one of 15 contiguous neighborhoods on Chicago's South Side.

APPROACH

Transcripts were systematically analyzed using qualitative techniques to identify emergent themes related to breast cancer treatment.

RESULTS

The concerns expressed most frequently were mistrust of the medical establishment and federal government, the effect of racism and lack of health insurance on quality of care, the impact of treatment on intimate relationships, and the negative effects of surgery, radiation therapy, and chemotherapy.

CONCLUSIONS

In addition to providing logistical and information support, strategies to reduce the breast cancer mortality gap should also address contextual factors important to quality of care. Specific interventions are discussed, including strategies to enhance trust, reduce race-related treatment differences, minimize the impact of treatment on intimate relationships, and reduce negative perceptions of breast cancer surgery, radiation therapy, and chemotherapy.

A randomized controlled trial of interventions to enhance patient-physician partnership, patient adherence and high blood pressure control among ethnic minorities and poor persons: study protocol NCT00123045

BACKGROUND

Disparities in health and healthcare are extensively documented across clinical conditions, settings, and dimensions of healthcare quality. In particular, studies show that ethnic minorities and persons with low socioeconomic status receive poorer quality of interpersonal or patient-centered care than whites and persons with higher socioeconomic status. Strong evidence links patient-centered care to improvements in patient adherence and health outcomes; therefore, interventions that enhance this dimension of care are promising strategies to improve adherence and overcome disparities in outcomes for ethnic minorities and poor persons.

OBJECTIVE

This paper describes the design of the Patient-Physician Partnership (Triple P) Study. The goal of the study is to compare the relative effectiveness of the patient and physician intensive interventions, separately, and in combination with one another, with the effectiveness of minimal interventions. The main hypothesis is that patients in the intensive intervention groups will have better adherence to appointments, medication, and lifestyle recommendations at three and twelve months than patients in minimal intervention groups. The study also examines other process and outcome measures, including patient-physician communication behaviors, patient ratings of care, health service utilization, and blood pressure control.

METHODS

A total of 50 primary care physicians and 279 of their ethnic minority or poor patients with hypertension were recruited into a randomized controlled trial with a two by two factorial design. The study used a patient-centered, culturally tailored, education and activation intervention for patients with active follow-up delivered by a community health worker in the clinic. It also included a computerized, self-study communication skills training program for physicians, delivered via an interactive CD-ROM, with tailored feedback to address their individual communication skills needs.

CONCLUSION

The Triple P study will provide new knowledge about how to improve patient adherence, quality of care, and cardiovascular outcomes, as well as how to reduce disparities in care and outcomes of ethnic minority and poor persons with hypertension.

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.

A plan for action: key perspectives from the racial/ethnic disparities strategy forum

CONTEXT

Racial and ethnic disparities in health care in the United States have been well documented, with research largely focusing on describing the problem rather than identifying the best practices or proven strategies to address it.

METHODS

In 2006, the Disparities Solutions Center convened a one-and-a-half-day Strategy Forum composed of twenty experts from the fields of racial/ethnic disparities in health care, quality improvement, implementation research, and organizational excellence, with the goal of deciding on innovative action items and adoption strategies to address disparities. The forum used the Results Based Facilitation model, and several key recommendations emerged.

FINDINGS

The forum's participants concluded that to identify and effectively address racial/ethnic disparities in health care, health care organizations should: (1) collect race and ethnicity data on patients or enrollees in a routine and standardized fashion; (2) implement tools to measure and monitor for disparities in care; (3) develop quality improvement strategies to address disparities; (4) secure the support of leadership; (5) use incentives to address disparities; and (6) create a message and communication strategy for these efforts. This article also discusses these recommendations in the context of both current efforts to address racial and ethnic disparities in health care and barriers to progress.

CONCLUSIONS

The Strategy Forum's participants concluded that health care organizations needed a multifaceted plan of action to address racial and ethnic disparities in health care. Although the ideas offered are not necessarily new, the discussion of their practical development and implementation should make them more useful.

Reducing disparities downstream: prospects and challenges

Addressing upstream or fundamental causes (such as poverty, limited education, and compromised healthcare access) is essential to reduce healthcare disparities. But such approaches are not sufficient, and downstream interventions, addressing the consequences of those fundamental causes within the context of any existing health system, are also necessary. We present a definition of healthcare disparities and two key principles (that healthcare is a social good and disparities in outcomes are a quality problem) that together provide a framework for addressing disparities downstream. Adapting the chronic care model, we examine a hierarchy of three domains for interventions (health system, provider-patient interactions, and clinical decision making) to reduce disparities downstream and discuss challenges to implementing the necessary changes.

Of goldfish tanks and moonlight tricks: can cultural competency ameliorate health disparities?

Within nursing, cultural competency is seen as an important mechanism for reducing racial and ethnic health disparities; however, after years of attempted implementation of "cultural competence," minimal evidence exists demonstrating a relationship between culturally competent interventions and improved health outcomes or reduced disparities. We examine how cultural competency as an intervention for tackling health disparities is undertheorized and misguided, and deflects attention and efforts needed to address broader social determinants of health. We provide a historical overview of cultural competency, critiques of the concept, and recommendations for moving beyond cultural competency as a means of diminishing health disparities.

Professional uncertainty and disempowerment responding to ethnic diversity in health care: a qualitative study

BACKGROUND

While ethnic disparities in health and health care are increasing, evidence on how to enhance quality of care and reduce inequalities remains limited. Despite growth in the scope and application of guidelines on "cultural competence," remarkably little is known about how practising health professionals experience and perceive their work with patients from diverse ethnic communities. Using cancer care as a clinical context, we aimed to explore this with a range of health professionals to inform interventions to enhance quality of care.

METHODS AND FINDINGS

We conducted a qualitative study involving 18 focus groups with a purposeful sample of 106 health professionals of differing disciplines, in primary and secondary care settings, working with patient populations of varying ethnic diversity in the Midlands of the UK. Data were analysed by constant comparison and we undertook processes for validation of analysis. We found that, as they sought to offer appropriate care, health professionals wrestled with considerable uncertainty and apprehension in responding to the needs of patients of ethnicities different from their own. They emphasised their perceived ignorance about cultural difference and were anxious about being culturally inappropriate, causing affront, or appearing discriminatory or racist. Professionals' ability to think and act flexibly or creatively faltered. Although trying to do their best, professionals' uncertainty was disempowering, creating a disabling hesitancy and inertia in their practice. Most professionals sought and applied a knowledge-based cultural expertise approach to patients, though some identified the risk of engendering stereotypical expectations of patients. Professionals' uncertainty and disempowerment had the potential to perpetuate each other, to the detriment of patient care.

CONCLUSIONS

This study suggests potential mechanisms by which health professionals may inadvertently contribute to ethnic disparities in health care. It identifies critical opportunities to empower health professionals to respond more effectively. Interventions should help professionals acknowledge their uncertainty and its potential to create inertia in their practice. A shift away from a cultural expertise model toward a greater focus on each patient as an individual may help.

Health advocacy for refugees: Medical student primer for competence in cultural matters and global health

PROBLEM BEING ADDRESSED

Canadian family physicians serve a patient population that is increasingly diverse, both culturally and linguistically. Family medicine needs to take a leadership role in developing social accountability and cultural sensitivity among physicians.

OBJECTIVE OF PROGRAM

To train medical students to work with newly arriving refugees, to foster competence in handling cultural issues, to raise awareness of global health, and to engage medical students in work with underserviced populations in primary care.

PROGRAM DESCRIPTION

The program is composed of an Internet-based training module and a self-assessment quiz focused on global and refugee health, a workshop to increase competence in cultural matters, an experience working with at least 1 refugee family at a shelter for newly arriving refugees, family physician mentorship, and a debriefing workshop at the end of the experience. Students who complete this program are eligible for further electives at a refugee health clinic.

CONCLUSION

The program has been received enthusiastically by students, refugees, and family physicians. Working with refugees provides a powerful introduction to issues related to global health and competence in cultural matters. The program also provides an opportunity for medical students to work alongside family physicians and nurtures their interest in working with disadvantaged populations.

Medical care of asylum seekers: a descriptive study of the appropriateness of nurse practitioners' care compared to traditional physician-based care in a gatekeeping system

Background

Medical care for asylum seekers is a complex and critical issue worldwide. It is influenced by social, political, and economic pressures, as well as premigration conditions, the process of migration, and postmigration conditions in the host country. Increasing needs and healthcare costs have led public health authorities to put nurse practitioners in charge of the management of a gatekeeping system for asylum seekers. The quality of this system has never been evaluated. We assessed the competencies of nurses and physicians in identifying the medical needs of asylum seekers and providing them with appropriate treatment that reflects good clinical practice.

Methods

This cross-sectional descriptive study evaluated the appropriateness of care provided to asylum seekers by trained nurse practitioners in nursing healthcare centers and by physicians in private practices, an academic medical outpatient clinic, and the emergency unit of the university hospital in Lausanne, Switzerland. From 1687 asylum seeking patients who had consulted each setting between June and December 2003, 450 were randomly selected to participate. A panel of experts reviewed their medical records and assessed the appropriateness of medical care received according to three parameters: 1) use of appropriate procedures to identify medical needs (medical history, clinical examination, complementary investigations, and referral), 2) provision of access to treatment meeting medical needs, and 3) absence of unnecessary medical procedures.

Results

In the nurse practitioner group, the procedures used to identify medical needs were less often appropriate (79% of reports vs. 92.4% of reports; p < 0.001). Nevertheless, access to treatment was judged satisfactory and was similar (p = 0.264) between nurse practitioners and physicians (99% and 97.6% of patients, respectively, received adequate care). Excessive care was observed in only 2 physician reports (0.8%) and 3 nurse reports (1.5%) (p = 0.481).

Conclusion

Although the nursing gatekeeping system provides appropriate treatment to asylum seekers, it might be improved with further training in recording medical history and performing targeted clinical examination.

Interventions to enhance breast cancer screening, diagnosis, and treatment among racial and ethnic minority women

The authors conduct a systematic review of the literature to identify interventions designed to enhance breast cancer screening, diagnosis, and treatment among minority women. Most trials in this area have focused on breast cancer screening, while relatively few have addressed diagnostic testing or breast cancer treatment. Among patient-targeted screening interventions, those that are culturally tailored or addressed financial or logistical barriers are generally more effective than reminder-based interventions, especially among women with fewer financial resources and those without previous mammography. Chart-based reminders increase physician adherence to mammography guidelines but are less effective at increasing clinical breast examination. Several trials demonstrate that case management is an effective strategy for expediting diagnostic testing after screening abnormalities have been found. Additional support for these and other proven health care organization-based interventions appears justified and may be necessary to eliminate racial and ethnic breast cancer disparities.

Primary care resident perceived preparedness to deliver cross-cultural care: an examination of training and specialty differences

OBJECTIVE

Previous research has shown that resident physicians report differences in training across primary care specialties, although limited data exist on education in delivering cross-cultural care. The goals of this study were to identify factors that relate to primary care residents' perceived preparedness to provide cross-cultural care and to explore the extent to which these perceptions vary across primary care specialties.

DESIGN

Cross-sectional, national mail survey of resident physicians in their last year of training.

PARTICIPANTS

Eleven hundred fifty primary care residents specializing in family medicine (27%), internal medicine (23%), pediatrics (26%), and obstetrics/gynecology (OB/GYN) (24%).

RESULTS

Male residents as well as those who reported having graduated from U.S. medical schools, access to role models, and a greater cross-cultural case mix during residency felt more prepared to deliver cross-cultural care. Adjusting for these demographic and clinical factors, family practice residents were significantly more likely to feel prepared to deliver cross-cultural care compared to internal medicine, pediatric, and OB/GYN residents. Yet, when the quantity of instruction residents reported receiving to deliver cross-cultural care was added as a predictor, specialty differences became nonsignificant, suggesting that training opportunities better account for the variability in perceived preparedness than specialty.

CONCLUSIONS

Across primary care specialties, residents reported different perceptions of preparedness to deliver cross-cultural care. However, this variation was more strongly related to training factors, such as the amount of instruction physicians received to deliver such care, rather than specialty affiliation. These findings underscore the importance of formal education to enhance residents' preparedness to provide cross-cultural care.

How quality improvement interventions can address disparities in depression

The quality of depression care, especially care received by minorities, needs improvement. Several interventions have been developed for the purpose of improving the quality of depression management in primary care, including quality improvement strategies employing disease management approaches, the chronic care model, and the Breakthrough Collaborative Series developed by the Institute for Healthcare Improvement. This article reviews these interventions and examines their potential to contribute to the improvement of depression care.

Disparities in depression care in managed care settings

The implementation of managed health care two decades ago produced sweeping changes in the delivery of health care. A large number of patients who have depression are cared for in managed care settings. Despite the fact that managed health care programs have offered the advantage of affordable and effective treatment of depression to many patients, racial and ethnic minorities remain underdiagnosed and undertreated. Diagnosis of depression, prescribing of antidepressant therapy, and referral for psychotherapy occur significantly less often in minority patients compared with whites. In the managed care setting, a number of issues at the physician level may negatively affect the quality of depression care, including attitudes toward psychiatry and mental health services, unfamiliarity with best practice guidelines for depression, and lack of cultural competency. On the other hand, a number of innovative approaches (eg, collaborative care) have demonstrated effectiveness in managed care settings. In some cases, physician education can be integrated with these approaches to assist health care providers in managed care organizations to provide the best possible depression care. This article focuses on issues relevant to depression care of minorities in the managed care sector, cites strategies for improving quality of depression care, and discusses implications for CME.
