Racial and ethnic differences in access to medical care

Robert Mayberry; Fatima Mili; Elizabeth Ofili

The authors’ review of the health services literature since the release of the landmark Report of the Secretary’s Task Force Report of Black and Minority Health in 1985 revealed significant differences in access to medical care by race and ethnicity within certain disease categories and types of health services. The differences are not explained by such factors as socioeconomic status (SES), insurance coverage, stage or severity of disease, comorbidities, type and availability of health care services, and patient preferences. Under certain circumstances when important variables are controlled, racial and ethnic disparities in access are reduced and may disappear. Nonetheless, the literature shows that racial and ethnic disparities persist in significant measure for several disease categories and service types. The complex challenge facing current and future researchers is to understand the basis for such disparities and to determine why disparities are apparent in some but not other disease categories and service types.

Objective To characterize maternal hypertension and related pregnancy complications among African-American and other women in the United States. Methods Using data from the National Hospital Discharge Survey, we analyzed the incidence and clinical spectrum of maternal hypertension among African- American women who delivered in hospital during 1998–1992. Maternal hypertension consisted of pregnancy-induced hypertension and chronic hypertension preceding pregnancy, including pregnancy-aggravated hypertension. Pregnancy-induced hypertension included preeclampsia, eclampsia, and transient hypertension. Incidence rates (per 1000 deliveries) and 95% confidence intervals (CI) were calculated by type of hypertension and demographic characteristics. Risk ratios and 95% CIs for adverse pregnancy outcomes among women with hypertension were also calculated. Results The overall incidence of all causes of maternal hypertension was 64.2, and of chronic hypertension preceding pregnancy it was 25.0 per 1000 deliveries among African-American women, an excess of 15.6 and 14.5 cases per 1000 deliveries, respectively, compared with rates for other women. The risks of preterm delivery and inadaquate fetal growth were similarly increased for all hypertensive women, regardless of race. However, hypertensive African- American women were at a threefold greater risk of pregnancies complicated by antepartum hemorrhage, an association that was not observed in other women. Development of preeclampsia and eclampsia irrespective of race was about four times higher among women with chronic hypertension preceding pregnancy than among those without chronic hypertension. Conclusion The excess incidence of maternal hypertension, particularly chronic hypertension, may contribute to adverse maternal and fetal pregnancy outcome and the disparity in outcomes observed between African-American and other women in the U.S. These findings provide a specific focus further clinical research and assessment of prenatal management in African-American Women.

Improving quality and reducing inequities: a challenge in achieving best care

Robert Mayberry; David Nicewander; Huanying Qin; David J. Ballard

The health care quality chasm is better described as a gulf for certain segments of the population, such as racial and ethnic minority groups, given the gap between actual care received and ideal or best care quality. The landmark Institute of Medicine report Crossing the Quality Chasm: A New Health System for the 21st Century challenges all health care organizations to pursue six major aims of health care improvement: safety, timeliness, effectiveness, efficiency, equity, and patient-centeredness. “Equity” aims to ensure that quality care is available to all and that the quality of care provided does not differ by race, ethnicity, or other personal characteristics unrelated to a patients reason for seeking care. Baylor Health Care System is in the unique position of being able to examine the current state of equity in a typical health care delivery system and to lead the way in health equity research. Its organizational vision, “culture of quality,” and involved leadership bode well for achieving equitable best care. However, inequities in access, use, and outcomes of health care must be scrutinized; the moral, ethical, and economic issues they raise and the critical injustice they create must be remedied if this goal is to be achieved. Eliminating any observed inequities in health care must be synergistically integrated with quality improvement. Quality performance indicators currently collected and evaluated indicate that Baylor Health Care System often performs better than the national average. However, there are significant variations in care by age, gender, race/ethnicity, and socioeconomic status that indicate the many remaining challenges in achieving “best care” for all.

BACKGROUND Self-monitoring of blood glucose (SMBG) is considered to be 1 of the cornerstones of diabetes self-management. It is unclear whether inadequate health literacy affects SMBG. OBJECTIVE The objective of this study was to examine the relationship between health literacy and SMBG. METHODS This was a cross-sectional survey of 189 patients with diabetes, aged 18 to 65 years, receiving care in a large urban, public health care setting. We measured health literacy using the shortened version of the Test of Functional Health Literacy in Adults. The diabetes care profile was used to determine the use of self-monitoring of blood glucose. RESULTS Most (60.9%) of the survey participants were assessed as functionally health literate. The majority (90.9%) of the study participants reported testing their blood sugar at least once daily. Although adequate health literacy was associated with recording of blood sugar testing (p = .049), we found no statistically significant relationship between health literacy and the frequency of SMBG. Persons self-reporting having diabetes for more than 10 years were less likely to self-monitor blood glucose (odds ratio, 0.33; 95% CI, 0.11-0.99). CONCLUSIONS SMBG frequency is not independently associated with health literacy, but SMBG result recording is noted among patients with inadequate literacy.

To identify the clinical correlates of recurrent heart failure hospitalization in a large urban hospital serving predominately African-American patients, and to provide further insight into modifiable risks for heart failure readmissions, a retrospective period prevalence review of the records of all adult patients admitted with a primary diagnosis of heart failure (International Classification of Diseases-9 code 428.0) between January and December 1995 was performed. The main outcome was the number of heart failure hospitalizations over 12 months. Twelve hundred patients were identified. Mean age was 64 +/- 16 years, 94% were black, 57% were women, and 40% were > or = 65 years old. Ninety-eight percent had a history of systemic hypertension and 55% had uncontrolled hypertension. Other comorbidities were left ventricular (LV) hypertrophy (64%), coronary artery disease (52%), and tobacco abuse (28%). Sixty-five percent of patients were on angiotensin-converting enzyme (ACE) inhibitors, 51% on calcium antagonists, and 8% on beta blockers. Most patients had suboptimal dosing of ACE inhibitors and there was inappropriate use of calcium antagonists in 56% of patients with moderate or severe systolic dysfunction. Diabetes mellitus and echocardiographic wall motion abnormality were independently associated with frequent admissions for women but not for men. Medication-related increase in heart failure hospitalization was seen for calcium antagonists in patients with severe LV dysfunction (odds ratio 2.24, 95% confidence intervals 1.0 to 5.03; p <0.03). Uncontrolled hypertension, underdosing of ACE inhibitors, and overuse of calcium antagonists in patients with significant LV dysfunction are potential targets for intervention.

African Americans have a higher prevalence of hypertension and poorer cardiovascular and renal outcomes than white Americans. The objective of this study was to determine whether a telephonic nurse disease management (DM) program designed for African Americans is more effective than a home monitoring program alone to increase blood pressure (BP) control among African Americans enrolled in a national health plan. A prospective randomized controlled study (March 2006-December 2007) was conducted, with 12 months of follow-up on each subject. A total of 5932 health plan members were randomly selected from the population of self-identified African Americans, age 23 and older, in health maintenance organization plans, with hypertension; 954 accepted, 638 completed initial assessment, and 485 completed follow-up assessment. The intervention consisted of telephonic nurse DM (intervention group) including educational materials, lifestyle and diet counseling, and home BP monitor vs. home BP monitor alone (control group). Measurements included proportion with BP < 120/80, mean systolic BP, mean diastolic BP, and frequency of BP self-monitoring. Results revealed that systolic BP was lower in the intervention group (adjusted means 123.6 vs. 126.7 mm Hg, P = 0.03); there was no difference for diastolic BP. The intervention group was 50% more likely to have BP in control (odds ratio [OR] = 1.50, 95% confidence interval [CI] 0.997-2.27, P = 0.052) and 46% more likely to monitor BP at least weekly (OR 1.46, 95% CI 1.07-2.00, P = 0.02) than the control group. A nurse DM program tailored for African Americans was effective at decreasing systolic BP and increasing the frequency of self-monitoring of BP to a greater extent than home monitoring alone. Recruitment and program completion rates could be improved for maximal impact.

Background Patients diagnosed with gonorrhea or chlamydia are at high risk for HIV and syphilis, and should be offered screening for both. Goal This study measures HIV and syphilis screening rates among Medicaid patients diagnosed with another sexually transmitted disease (STD). Study Design Using 1998 Medicaid claims data from 4 states, we identified individuals diagnosed with gonorrhea, urogenital chlamydia, or pelvic inflammatory disease, and then measured the proportion receiving screening tests for HIV and syphilis. Results Only 25% of STD-diagnosed Medicaid patients received screening tests for syphilis and only 15% for HIV. We found significant state-to-state variability in screening rates. Conclusion Medicaid patients diagnosed with a nonbloodborne STD represent a high-risk group that is not adequately screened for syphilis and HIV despite repeated contact with medical professionals. Interventions should focus on eliminating missed opportunities for screening these high-risk individuals.

PURPOSE The purpose of this paper is to pilot-test the feasibility and impact of protocol-driven point-of-care HbAlc testing on levels of glycemic control and on rates of diabetic regimen intensification in an urban community health center serving low-income patients. DESIGN/METHODOLOGY/APPROACH The paper suggests a primary care process re-design, using point of care finger-stick HbA1c testing under a standing order protocol that provided test results to the provider at patient visit. FINDINGS The paper finds that the protocol was well received by both nurses and physicians. HbA1c testing rates increased from 73.6 percent to 86.8 percent (p = 0.40, n = 106). For the 69 patients who had both pre- and post-intervention results, HbAlc levels decreased significantly from 8.55 to 7.84 (p = 0.004, n = 69). At baseline, the health center as a system was relatively ineffective in responding to elevated HbA1c levels. An opportunity to intensify, i.e. a face-to-face visit with lab results available, occurred for only 68.6 percent of elevated HbAlc levels before the intervention, vs. 100 percent post-intervention (p < 0.001). Only 28.6 percent of patients with HbAlc levels >8.0 had their regimens intensified in the pre-intervention phase, compared with 53.8 percent in the post-intervention phase (p = 0.03). RESEARCH LIMITATIONS/IMPLICATIONS This was a pilot-study in one urban health center. Larger group-randomized controlled trials are needed. PRACTICAL IMPLICATIONS The health centers performance as a system, improved significantly as a way of intensifying diabetic regimens thereby achieving improved glycemic control. ORIGINALITY/VALUE This intervention is feasible, replicable and scalable and does not rely on changing physician behaviors to improve primary care diabetic outcomes.

Peer Training of Community Health Workers to Improve Heart Health Among African American Women

Robina Josiah Willock; Robert Mayberry; Fengxia Yan; Pamela Daniels

Introduction. Training community health workers (CHWs) builds a workforce that is essential to addressing the chronic disease crisis. This article describes a highly replicable CHW training program that targets heart disease risk among African American women. Background. African American women suffer disproportionately from heart disease mortality and morbidity. Well-trained CHWs are uniquely positioned to close this disparity gap. Method. We used a Learning Circle approach to train CHWs in heart health education. The curriculum blended web-based, self-directed learning and in-person peer coaching. CHWs learned through (a) peer-to-peer sharing, (b) problem solving and brainstorming, and (c) leadership and experiential activities. Training evaluation measures were CHWs’ (a) self-confidence, (b) heart health knowledge, (c) satisfaction with training, (d) training retention, and (e) replication of training within 90 days after training. Results. This training resulted in appreciable effects on four of five outcome measures. Heart health knowledge increased significantly among experienced CHWs (p = .011). CHWs were satisfied with training and retention was 100%. CHWs initiated and subsequently delivered 122 person hours of community heart health education and CHW training in their communities. Discussion/Conclusion. CHW heart health training using Learning Circles is a practical and replicable method of training CHWs and holds significant potential for building capacity in resource-poor community organizations.
