ABSTRACT

Nonadherence to diabetes medication is a common and costly problem, significantly precluding the evidence-based benefits of diabetes care. Nonadherence is also a poorly understood multifactorial behavior, particularly among African Americans with type 2 diabetes receiving care in under-resourced primary care settings. We investigated several known or suspected individual-level factors influencing diabetes medication adherence among a predominantly African American group of adults with diabetes at a local community health center. Overall diabetes medication adherence was observed to be surprisingly low at 23% (95% confidence interval (CI) = 19%-26%) and did not differ by medication type (p=.435). Common sociodemographic factors were poor predictors of adherence. However, self-perceived health and presence of comorbid conditions were significant. The strongest independent predictors of diabetes medication adherence in this population were a heart attack and having maintained a desired level of glycemic control, indicating the importance of specific comorbidities and motivation for self-care in tailoring interventions to improve adherence.

ABSTRACT

Red blood cell (RBC) hemolysis is one of the most common storage lesions in packed RBCs (pRBC). Older units of pRBCs, especially those > 21 days old, have increasing levels of hemolysis leading to increased oxidative stress and premature platelet activation. This effect can mostly be attributed to the increase of cell-free hemoglobin (Hb). Therefore, removal of cell-free Hb from pRBCs prior to transfusion could mitigate these deleterious effects. We propose a new method for the removal of Hb from pRBCs using zinc beads. Prepared Hb solutions and pRBCs were treated with zinc beads using two different protocols. UV-Vis spectrophotometry was used to determine Hb concentrations, before and after treatment. Experiments were run in triplicate and paired t tests were used to determine significant differences between groups. Zinc beads removed on average 94% of cell-free Hb within 15 min and 78% Hb from pRBCs (p < 0.0001), demonstrating a maximum binding capacity ~ 66.2 ± 0.7 mg Hb/mL beads. No differences in RBC morphology or deformability were observed after treatment. This study demonstrates the feasibility of using zinc beads for the rapid and targeted removal of Hb from pRBC units. Further investigation is needed to scale this method for large volume removal.

ABSTRACT

PURPOSE: The purpose of this study is to characterize risk factors associated with type 2 diabetes in young adults aged 18 to 29 years to develop a noninvasive risk assessment tool for use with younger American populations. METHODS: The self-assessment tool was developed with the Strong Heart Family Study data. A total of 590 young American Indian adults (242 men) who had normoglycemia and were not receiving diabetes treatment were included. Risk factors recommended by the American Diabetes Association were used to assess diabetes risk in these young adults. A logistic regression model was developed to calculate the predicted probability. The area under the receiver operating characteristic curve was used to evaluate the model. RESULTS: The final model showed that parental history of diabetes, obesity level, alcohol consumption, and high fasting glucose, even within normal range, were significantly associated with onset of prediabetes/diabetes in 5 years. The area under the receiver operating characteristic curve value was 0.68 with original and validated data, indicating that the risk assessment tool had reasonably good discrimination ability. CONCLUSIONS: This new noninvasive screening tool, based on data from American Indian young adults, has potential to screen young adults' early-onset diabetes risk. Future studies are warranted to test this risk assessment tool in other racial/ethnic young adults.

ABSTRACT

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.

ABSTRACT

OBJECTIVES: To examine the process of community-campus engagement in an initiative developed to build evaluation capacities of community-based organizations (CBOs). METHODS: Evaluability assessment, capacity-building, self administered surveys and semi-structured interviews were conducted from 2004 to 2007 and analyzed through transcript assessment and SPSS to identify trends, relationships and capacity changes over time. RESULTS: Evaluability assessment identified CBO strengths in program planning and implementation and challenges in measurable objective development, systematic use of mixed methods, data management and analysis. Evaluability assessment informed evaluation capacity-building (ECB) trainings, teleconferences and webinars that resulted in statistically significant improvements in evaluation knowledge, skills, and abilities. Post-initiative interviews indicated CBO preferences for face-to-face training in logic model development, mixed method data collection and analysis. CONCLUSION: This report illustrates the use of mixed methods to plan, implement and evaluate a model to catalyze CBOs systematic assessment of prevention initiatives and considerations in evaluation capacity-building.

ABSTRACT

The catalytic potential of community-based organizations to promote health, prevent disease, and address racial, ethnic, and socio-economic disparities in local communities is well recognized. However, many CBOs, particularly, small- to medium-size organizations, lack the capacity to plan, implement, and evaluate their successes. Moreover, little assistance has been provided to enhance their capacity and the effectiveness of technical assistance to enhance capacity is likewise limited. A unique private-academic partnership is described that simultaneously conducted program evaluation and addressed the capacity needs of 24 CBOs funded by the Pfizer Foundation Southern HIV/AIDS Prevention Initiative. Assessments of key program staff members at 12 and 18 months after the initial cross-site program assessment survey indicated a significant improvement in the CBOs' knowledge, skills, and abilities and a substantial reduction in their technical assistance needs for HIV/AIDS prevention. Full participation of CBOs in technical assistance and a concurrent empowerment evaluation framework were necessary to enhance prevention capacity.

ABSTRACT

Community-based organizations (CBOs) have the potential to promote and sustain health, prevent disease, and address health disparities, but many lack the capacity to do so. An assessment of the 20 CBOs receiving supplemental grant funding from the Pfizer Foundation Southern HIV/AIDS Prevention Initiative indicated a high level of knowledge for developing goals and objectives (mean score=3.08 on a scale of 0 (none) to 4 (extensive)) and high self-assessed abilities to conduct six of 20 specific intervention activities, including the development of community relationships and coalitions. Lower knowledge and skill levels were observed for intervention evaluation. While CBOs of this Initiative have established prerequisite abilities, they have self-acknowledged needs for technical assistance to maximize HIV/AIDS prevention capacity.

ABSTRACT

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 patient's 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.

ABSTRACT

BACKGROUND: Blacks are less likely than whites to develop bladder carcinoma. However, once they are diagnosed, black patients experience poorer survival. The authors investigated which factors were related to survival differences in black patients and white patients with bladder carcinoma stratified by extent of disease. METHODS: A population-based cohort of black patients with bladder carcinoma and a random sample of frequency-matched white patients with bladder carcinoma, stratified by age and gender, were identified through cancer registry systems in Atlanta, New Orleans, and San Francisco/Oakland. Patients had no previous cancer history and were ages 20-79 years at the time they were diagnosed with bladder carcinoma in 1985-1987. Medical records were reviewed at initial diagnosis, and 77% of patients were interviewed. Tumor grade, T classification, and other variables, including age, socioeconomic position, symptom duration, smoking history, and comorbidities, were recorded. Survival of black patients and white patients by extent of disease was modeled using Cox regression analysis. RESULTS: A greater proportion of black patients had histologic types of tumors that were associated with poorer survival. Among those with pure urothelial carcinoma, black patients had greater extent of disease at the time of diagnosis. Within specific extent-of-disease categories, there was some evidence of poorer survival for black patients with T2 tumors and strong evidence of poorer survival among those with T3 tumors compared with white patients. Black patients with muscle-invasive carcinoma who died within 6 months of diagnosis tended to present with life-threatening symptoms. Black patients and white patients did not differ with respect to diagnostic tests performed or therapy given. CONCLUSIONS: Black patients with bladder carcinoma had poorer survival due to greater extent of disease at diagnosis and a higher proportion of more aggressive histologies compared with white patients. Within urothelial carcinomas, by extent of disease (clinical/pathologic stage) these black/white survival differences were limited to patients with muscle invasion (T2 and T3 tumors).

ABSTRACT

This cross-sectional study explored whether there are age-specific differences in breast cancer-related knowledge, beliefs, and screening behaviors among low-income, elderly black women. Data were collected at senior citizen facilities from 214 black women aged 65 and older. Differences in knowledge, beliefs, and screening practices across three age groups were assessed by chi-square tests. Logistic regression modeling was used to determine the effect of these factors on compliance with American Cancer Society (ACS) screening guidelines. Age was inversely associated with knowledge and screening practices. The youngest group (65-74) was about twice as likely as the oldest group (85 and over) to correctly recognize breast cancer risk factors. About 50% of the oldest women compared to about 20% of the youngest women believed their risk for breast cancer was nil. The oldest group was also least likely to have had a mammogram or clinical breast examination within the past year, as recommended by the ACS. Our results suggest that educating elderly women, especially those 85 and over, about breast cancer and screening may lead to higher compliance with ACS recommendations.

ABSTRACT

BACKGROUND: Interest in alternative and complementary medical practices has grown considerably in recent years. Previous surveys have examined attitudes of the general public and practicing physicians. This study examined the training, experience, and attitudes of medical school faculty, who have the primary responsibility for the education of future family physicians. METHODS: A 24-item, self-administered questionnaire was distributed to all 200 faculty at a medical school with a mission of training primary care physicians. RESULTS: Of 30 therapies listed, 5 were considered legitimate medical practices by more than 70% of the faculty. Eighty-five percent of the respondents reported some training in alternative medical therapies, and 62% were interested in additional training. Eighty-three percent of the faculty reported personal experience with alternative therapies and most rated these as effective. Eighty-five percent of the respondents indicated that their general attitude toward alternative medicine is positive. CONCLUSIONS: The results indicate that respondents have had substantial exposure to complementary therapies, are interested in learning more about these therapies, and have generally positive attitudes toward alternative medical practices and their use. Because of the role of these therapies in prevention, the positive attitudes might reflect the mission of this medical school to train primary care physicians.
