Diabetes Health Disparities: A Systematic Review of Health Care Interventions

Racial and ethnic minorities bear a disproportionate burden of the diabetes epidemic; they have higher prevalence rates, worse diabetes control, and higher rates of complications. This article reviews the effectiveness of health care interventions at improving health outcomes and/or reducing diabetes health disparities among racial/ethnic minorities with diabetes. Forty-two studies met inclusion criteria. On average, these health care interventions improved the quality of care for racial/ethnic minorities, improved health outcomes (such as diabetes control and reduced diabetes complications), and possibly reduced health disparities in quality of care. There is evidence supporting the use of interventions that target patients (primarily through culturally tailored programs), providers (especially through one-on-one feedback and education), and health systems (particularly with nurse case managers and nurse clinicians). More research is needed in the areas of racial/ethnic minorities other than African Americans and Latinos, health disparity reductions, long-term diabetes-related outcomes, and the sustainability of health care interventions over time.

Fear, fatalism and breast cancer screening in low-income African-American women: the role of clinicians and the health care system.

BackgroundAfrican-American women have the highest breast cancer death rates of all racial/ethnic groups in the US. Reasons for these disparities are multi-factorial, but include lower mammogram utilization among this population. Cultural attitudes and beliefs, such as fear and fatalism, have not been fully explored as potential barriers to mammography among African-American women.ObjectiveTo explore the reasons for fear associated with breast cancer screening among low-income African-American women.MethodsWe conducted four focus groups (n = 29) among a sample of African-American women at an urban academic medical center. We used trained race-concordant interviewers with experience discussing preventive health behaviors. Each interview/focus group was audio-taped, transcribed verbatim and imported into Atlas.ti software. Coding was conducted using an iterative process, and each transcription was independently coded by members of the research team.Main ResultsSeveral major themes arose in our exploration of fear and other psychosocial barriers to mammogram utilization, including negative health care experiences, fear of the health care system, denial and repression, psychosocial issues, delays in seeking health care, poor health outcomes and fatalism. We constructed a conceptual model for understanding these themes.ConclusionsFear of breast cancer screening among low-income African-American women is multi-faceted, and reflects shared experiences within the health care system as well as the psychosocial context in which women live. This study identifies a prominent role for clinicians, particularly primary care physicians, and the health care system to address these barriers to mammogram utilization within this population.

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.

Feasibility and Usability of a Text Message-Based Program for Diabetes Self-Management in an Urban African-American Population

Purpose: We pilot-tested a text message-based diabetes care program in an urban African-American population in which automated text messages were sent to participants with personalized medication, foot care, and appointment reminders and text messages were received from participants on adherence. Methods: Eighteen patients participated in a 4-week pilot study. Baseline surveys collected data about demographics, historical cell phone usage, and adherence to core diabetes care measures. Exit interview surveys (using close-coded and open-ended questions) were administered to patients at the end of the program. A 1-month follow-up interview was conducted surveying patients on perceived self-efficacy. Wilcoxon signed-rank tests were used to compare baseline survey responses about self-management activities to those at the pilots end and at 1-month follow-up. Results: Eighteen urban African-American participants completed the pilot study. The average age was 55 and the average number of years with diabetes was 8. Half the participants were initially uncomfortable with text messaging. Example messages include “Did you take your diabetes medications today” and “How many times did you check your feet for wounds this week?” Participants averaged 220 text messages with the system, responded to messages 80% of the time, and on average responded within 6 minutes. Participants strongly agreed that text messaging was easy to perform and helped with diabetes self-care. Missed medication doses decreased from 1.6 per week to 0.6 (p = .003). Patient confidence in diabetes self-management was significantly increased during and 1 month after the pilot (p = .002, p = .008). Conclusions: Text messaging may be a feasible and useful approach to improve diabetes self-management in urban African Americans.

Barriers and Facilitators to Shared Decision-making Among African-Americans with Diabetes

ABSTRACTINTRODUCTIONShared decision-making (SDM) between patients and their physicians is associated with improved diabetes health outcomes. African-Americans have less SDM than Whites, which may contribute to diabetes racial disparities. To date, there has been little research on SDM among African-Americans.OBJECTIVEWe explored the barriers and facilitators to SDM among African-Americans with diabetes.METHODSQualitative research design with a phenomenological methodology using in-depth interviews (n = 24) and five focus groups (n = 27). Each interview/focus group was audio-taped and transcribed verbatim, and coding was conducted using an iterative process. Participants: We utilized a purposeful sample of African-American adult patients with diabetes. All patients had insurance and received their care at an academic medical center.RESULTSPatients identified multiple SDM barriers/facilitators, including the patient/provider power imbalance that was perceived to be exacerbated by race. Patient-related factors included health literacy, fear/denial, family experiences and self-efficacy. Reported physician-related barriers/facilitators include patient education, validating patient experiences, medical knowledge, accessibility and availability, and interpersonal skills.DISCUSSIONBarriers/facilitators of SDM exist among African-Americans with diabetes, which can be effectively addressed in the outpatient setting. Primary care physicians, particularly academic internists, may be uniquely situated to address these barriers/facilitators and train future physicians to do so as well.

The use of quality improvement and health information technology approaches to improve diabetes outcomes in African American and Hispanic patients.

Differences in rates of diabetes-related lower extremity amputations represent one of the largest and most persistent health disparities found for African Americans and Hispanics compared with Whites in the United States. Since many minority patients receive care in underresourced settings, quality improvement (QI) initiatives in these settings may offer a targeted approach to improve diabetes outcomes in these patient populations. Health information technology (health IT) is widely viewed as an essential component of health care QI and may be useful in decreasing diabetes disparities in underresourced settings. This article reviews the effectiveness of health care interventions using health IT to improve diabetes process of care and intermediate diabetes outcomes in African American and Hispanic patients. Health IT interventions have addressed patient, provider, and system challenges in the provision of diabetes care but require further testing in minority patient populations to evaluate their effectiveness in improving diabetes outcomes and reducing diabetes-related complications.

Early Lessons From An Initiative On Chicago’s South Side To Reduce Disparities In Diabetes Care And Outcomes

Interventions to improve health outcomes among patients with diabetes, especially racial or ethnic minorities, must address the multiple factors that make this disease so pernicious. We describe an intervention on the South Side of Chicago-a largely low-income, African American community-that integrates the strengths of health systems, patients, and communities to reduce disparities in diabetes care and outcomes. We report preliminary findings, such as improved diabetes care and diabetes control, and we discuss lessons learned to date. Our initiative neatly aligns with, and can inform the implementation of, the accountable care organization-a delivery system reform in which groups of providers take responsibility for improving the health of a defined population.

National Prevalence of Lifestyle Counseling or Referral Among African-Americans and Whites with Diabetes

Modifiable risk factors such as diet and physical activity contribute to racial disparities among patients with diabetes. Despite this, little is known about how frequently physicians provide counseling or referral to address these risk factors, or whether such rates differ by patient race. We analyzed cross-sectional data from the 2002–2004 National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey. We used logistic regression to investigate the relationship between counseling/referral for nutrition or exercise and patient factors, provider factors, and geographic location, with a focus on whether counseling rates were independently associated with patient race. Overall, counseling/referral for nutrition occurred in 36% of patient visits and counseling/referral for exercise occurred in 18% of patient visits. After adjusting for patient, physician, and practice characteristics, there was no statistically significant association between race and counseling/referral for nutrition (odds ratio for African-Americans compared to whites [OR] 1.00, 95% confidence intervals [CI] 0.71–1.41) or for exercise (OR 0.74, CI 0.49–1.11). Significant predictors of counseling/referral for both lifestyle interventions included younger patient age, private insurance, and treatment by a primary care provider. Rates of lifestyle modification counseling/referral were similarly low among African-Americans and whites in this national study. Our results highlight a need for interventions to enhance physician counseling for patients with diabetes, particularly those at high-risk for diabetes-associated morbidity and mortality, such as racial/ethnic minorities.BackgroundModifiable risk factors such as diet and physical activity contribute to racial disparities among patients with diabetes.

How Do Mobile Phone Diabetes Programs Drive Behavior Change? Evidence From a Mixed Methods Observational Cohort Study

Purpose The purpose of this study was to investigate the behavioral effects of a theory-driven, mobile phone–based intervention that combines automated text messaging and remote nursing, using an automated, interactive text messaging system. Methods This was a mixed methods observational cohort study. Study participants were members of the University of Chicago Health Plan (UCHP) who largely reside in a working-class, urban African American community. Surveys were conducted at baseline, 3 months (mid-intervention), and 6 months (postintervention) to test the hypothesis that the intervention would be associated with improvements in self-efficacy, social support, health beliefs, and self-care. In addition, in-depth individual interviews were conducted with 14 participants and then analyzed using the constant comparative method to identify new behavioral constructs affected by the intervention. Results The intervention was associated with improvements in 5 of 6 domains of self-care (medication taking, glucose monitoring, foot care, exercise, and healthy eating) and improvements in 1 or more measures of self-efficacy, social support, and health beliefs (perceived control). Qualitatively, participants reported that knowledge, attitudes, and ownership were also affected by the program. Together these findings were used to construct a new behavioral model. Conclusions This study’s findings challenge the prevailing assumption that mobile phones largely affect behavior change through reminders and support the idea that behaviorally driven mobile health interventions can address multiple behavioral pathways associated with sustained behavior change.

Gender Differences in Diabetes-related Lower Extremity Amputations

BackgroundDiabetes is a major cause of morbidity and mortality in the United States, with much of the economic and social costs related to macrovascular and microvascular complications, such as myocardial infarctions, renal failure, and lower extremity amputations. While racial/ethnic differences in diabetes are well documented, less attention has been given to differences in diabetes outcomes by gender.Questions/purposesDoes gender influence the rate of diabetes-related lower extremity amputations and/or the rate of mortality after amputation?MethodsI reviewed the literature utilizing peer-reviewed publications found through MEDLINE searches.Where are we now?Major complex gender differences exist in diabetes-related lower extremity amputations: men are more likely to undergo lower extremity amputations, but women apparently have higher mortality related to these procedures. The reasons for such differences are not entirely clear, but it appears biologic factors may play important roles (increased rates of peripheral vascular disease and peripheral neuropathy in men, interaction between gender and cardiac mortality in women).Where do we need to go?More research is warranted to confirm gender differences in diabetes-related lower extremity amputation mortality and explore underlying mechanisms for the gender differences in lower extremity amputations and its associated mortality.How do we get there?Exploring gender disparities in diabetes-related outcomes, such as lower extremity amputations, will need to become a national priority from a research (eg, National Institutes of Health) and policy (eg, Centers for Medicare and Medicaid Services) perspective. Only when we have a better understanding of the causes of such differences can we begin to make strides in addressing them.
