Developing Health Care Faculty to Address the Needs of North Carolina's Diverse Populations.

Addressing community needs improves population health and the well-being of health care providers. The development of the health care workforce requires faculty to address the needs of North Carolina's diverse and rural populations. This can be best accomplished by building interdisciplinary and cross-functional service-learning experiences and developing community-academic partnerships and coalitions.

Design and rationale of GUARDD-US: A pragmatic, randomized trial of genetic testing for APOL1 and pharmacogenomic predictors of antihypertensive efficacy in patients with hypertension.

RATIONALE AND OBJECTIVE: APOL1 risk alleles are associated with increased cardiovascular and chronic kidney disease (CKD) risk. It is unknown whether knowledge of APOL1 risk status motivates patients and providers to attain recommended blood pressure (BP) targets to reduce cardiovascular disease. STUDY DESIGN: Multicenter, pragmatic, randomized controlled clinical trial. SETTING AND PARTICIPANTS: 6650 individuals with African ancestry and hypertension from 13 health systems. INTERVENTION: APOL1 genotyping with clinical decision support (CDS) results are returned to participants and providers immediately (intervention) or at 6 months (control). A subset of participants are re-randomized to pharmacogenomic testing for relevant antihypertensive medications (pharmacogenomic sub-study). CDS alerts encourage appropriate CKD screening and antihypertensive agent use. OUTCOMES: Blood pressure and surveys are assessed at baseline, 3 and 6 months. The primary outcome is change in systolic BP from enrollment to 3 months in individuals with two APOL1 risk alleles. Secondary outcomes include new diagnoses of CKD, systolic blood pressure at 6 months, diastolic BP, and survey results. The pharmacogenomic sub-study will evaluate the relationship of pharmacogenomic genotype and change in systolic BP between baseline and 3 months. RESULTS: To date, the trial has enrolled 3423 participants. CONCLUSIONS: The effect of patient and provider knowledge of APOL1 genotype on systolic blood pressure has not been well-studied. GUARDD-US addresses whether blood pressure improves when patients and providers have this information. GUARDD-US provides a CDS framework for primary care and specialty clinics to incorporate APOL1 genetic risk and pharmacogenomic prescribing in the electronic health record.

Impact of Hurricane Matthew on Diabetes Self-Management and Outcomes.

BACKGROUND: Individuals with diabetes require extensive self-management. Little is known about how Hurricane Matthew (Matthew) or Hurricane Florence (Florence) impacted diabetes self-management and outcomes in Robeson County, North Carolina. METHODS: Mixed methods were used to assess the impact of hurricanes on diabetes self-management and outcomes. Individuals with diabetes were recruited for focus groups to understand the perceived impact on diabetes self-management. Health care providers were recruited for parallel key informant interviews. Mean hemoglobin A1c (HbA1c) and frequency of diabetic ketoacidosis (DKA) from hospital data six months before and after Matthew were compared using Student t-tests. RESULTS: A demographic breakdown of 34.25% white, 21.70% Black or African American, and 21.38% American Indian or Alaska Native was observed from focus groups. Qualitative results highlight a limited access to a balanced diet and medications. No significant differences were found between mean HbA1c values before and after Matthew (before Matthew: mean HbA1c 8.34 ± 1.87%; after Matthew: mean HbA1c 8.31 ± 1.93 %; P = .366). The period prevalence (PP) of DKA was higher after Matthew than before (before Matthew: 39 cases out of 4,025 visits, PP = .010; after Matthew: 87 cases out of 3,779 visits, PP = .023; P <.0001). LIMITATIONS: Limitations include non-random sampling and limited sample sizes. Also, the cross-sectional panel approach did not follow the same individuals over time. CONCLUSIONS: The period prevalence of DKA was higher in the six-month time period following Matthew compared to before the hurricane. Future interventions may improve outcomes via increased access to foods and medications recommended for those with diabetes.

County-level correlates of dental service utilization for low income pregnant women. Ecologic study of the North Carolina Medicaid for Pregnant Women (MPW) program.

BACKGROUND: Dental care utilization for low income pregnant women is met with challenges in the traditional dentist-centered model of care. County-level measures provide insights for policy and roles for stakeholders that extend beyond the dentist-patient relationship. We examined county-level data to generate hypotheses about factors that influence utilization of dental services in North Carolina's Medicaid for Pregnant Women (MPW) program. METHODS: County-level Medicaid utilization data for dental services for 2014-2016 were pooled to get mean county estimates of dental utilization in the MPW program. Descriptive statistics and multivariate regression models of dental utilization and county-level measures are presented. Data used were collected by NC Child and the Robert Wood Johnson Foundation's County Health Rankings Reports. USDA Economic Research Service data were used to categorize counties in terms of Farming, Recreation, Persistent Poverty, and metro/non-metro status using Rural Urban Continuum Codes. RESULTS: Dental utilization ranged from 1-26% with a median of 8.5% across the 100 counties of North Carolina. Strong patterns linking utilization of dental services in the MPW program to contextual social measures of well-being emerged, specifically, increased reporting of child abuse and neglect, elevated infant mortality, poor quality of life, and worse ranking in years of potential life lost. Counties with persistent poverty had lower rates of dental utilization. CONCLUSIONS: Utilization of dental services in the MPW program is generally low. Patterns identify the potential for enhancing community-clinical linkages to improve birth outcomes and care coordination for pregnant women to enhance dental utilization in this population. Dental coverage in the Medicaid program in most states is administered separately from medical coverage. The separation of the funding mechanisms adds a further layer of complexity to care integration. Efforts to enhance dental care for pregnant women in the Medicaid program may benefit from policy that aligns incentives for care coordination within the community. Policy that extends the window of eligibility for dental benefits to 24 months after the birth of the child will help women complete the dental treatment that is needed. This also leverages the value of care coordination for community stakeholders from diverse child health sectors.

Resilience, Self-compassion, and Mental Health Outcomes: Rebuilding Eastern North Carolina After Natural Disasters.

Natural disasters have occurred more frequently in Eastern North Carolina in recent years. Evidence supports that repeated exposure to natural disasters may have lasting mental health impacts among vulnerable populations. Greater access to mental health services may aid in ensuring equitable access to needed care and promote resilience.

Testing a Culturally Adapted Colorectal Cancer Screening Decision Aid Among American Indians: Results from a Pre-Post Trial.

Purpose: American Indian adults have not experienced decreases in colorectal cancer (CRC) incidence and mortality observed in other races or ethnic groups and their screening rates are low. Decision aids that explain available CRC screening options are one potential strategy to promote screening. The goal of this study was to test the effect of a culturally adapted decision aid on CRC-related outcomes among American Indian adults, including screening-related knowledge, attitudes, self-efficacy, intentions, and screening modality preferences. Methods: We recruited American Indian adults aged 50-75 years who were not current with CRC screening. Participants viewed a 9-min multimedia decision aid that used narrative vignettes to provide educational information about screening along with messages to address culturally specific barriers and values uncovered in formative research. We conducted a single-arm (pre-post) study and assessed screening-related outcomes at baseline and immediately after viewing the decision aid. Results: Among n=104 participants, knowledge scores increased from a mean of 36% correct to 76% correct. Participants also had statistically significant increases in positive attitudes, perceived social norms, self-efficacy, and intent. The proportion of participants who identified a preference for a specific CRC screening modality rose from 81% identified at pre-intervention to 93% post-intervention (p=0.013). Conclusion: Our study provides promising new findings that our culturally adapted decision aid is efficacious in educating American Indian adults about CRC screening and increases their screening intentions and ability to state modality preferences. Future research is needed to test the decision aid as a component of CRC screening interventions with American Indian adults.

Spirituality, Coping, and Resilience Among Rural Residents Living with Chronic Kidney Disease.

Spirituality, an established resource within rural America, serves as an important coping mechanism for crises of chronic illness. We examined the effects of spirituality on chronic kidney disease (CKD) maintenance in the rural community of Robeson County, North Carolina. We conducted nine focus group discussions and 16 interviews involving 80 diverse key informants impacted by CKD. As disenfranchised patients, they locally engaged in spirituality which mobilized personal and social resources and elicited support from a transcendent authority. Our participants developed a heuristic and aesthetic understanding of disease, built resilience and self-care skills, and improved overall coping and survival.

Addressing health inequalities in diverse, rural communities: An unmet need.

Research on rural health needs to represent the diverse demographics of these regions by carefully considering the distinct characteristics, inequities, and stressors occurring in rural communities. Drawing from our own findings and other empirical investigations examining diverse rural communities, we propose several considerations to guide future endeavors toward more inclusive rural health research. These include population-health assessment tools that consider minority stress and intervention strategies designed to reflect both the environmental and socio-cultural contexts of rural residents.

Regional After-Action Review Among Local Health Department Personnel After Hurricane Matthew in Eastern North Carolina, United States.

Hurricane Matthew impacted eastern North Carolina during October 2016. A regional after-action exercise was conducted as a moderated discussion using an adaptation of Federal Emergency Management Agency's (FEMA's) after-action report format to allow health departments to communicate lessons learned across jurisdictional lines. Forty-one professionals from 18 counties participated in a 2-hour workshop. Information on strengths, weaknesses, and recommendations was collected in small-group format, organized into county clusters by hazard mitigation regions and by 3 professional roles (health director, nursing director, and preparedness coordinator). Interagency agreements varied by county, depending on regularity of hurricanes and flooding. Improvement opportunities included enhanced coordination with American Red Cross in shelter operations and opening more special medical needs shelters. Participants emphasized successful coordination with county emergency management leaders. A regional after-action exercise designed as a moderated workshop focusing on the public health response provided an opportunity to exchange strengths and lessons learned after Hurricane Matthew in eastern North Carolina. This after-action approach may be useful for similar local health jurisdictions to build regional consensus for future disaster response planning and training.

Perspectives of American Indians in Eastern North Carolina on Socio-cultural Factors that Influence Colorectal Cancer Screening Decisions.

American Indians (AI) have disproportionately high rates of colorectal cancer (CRC), but there is relatively little research focused on developing AI CRC screening interventions. We held six focus groups with AIs in rural Eastern U.S. (n=74) and analyzed the qualitative data from them in order to identify individual and socio-cultural factors that influence AI CRC screening decisions. Screening fear and anxiety was a central theme of the focus groups. For example, participants told stories about how late-stage cancer diagnoses and deaths in the community contributed to their fears and cancer fatalism. Furthermore, CRC screening fears were reinforced by health communication norms that limited productive conversations about CRC screening. Our findings indicate that culturally adapted interventions, such as CRC screening decision aids, are needed to help AIs communicate and make informed decisions about CRC screening with support from family and health care providers. More research is needed on the influence of these interventions on CRC screening intentions, social norms, and shared decision-making.

Does utilization of screening mammography explain racial and ethnic differences in breast cancer?

BACKGROUND: Reasons for persistent differences in breast cancer mortality rates among various racial and ethnic groups have been difficult to ascertain. OBJECTIVE: To determine reasons for disparities in breast cancer outcomes across racial and ethnic groups. DESIGN: Prospective cohort. SETTING: The authors pooled data from 7 mammography registries that participate in the National Cancer Institute-funded Breast Cancer Surveillance Consortium. Cancer diagnoses were ascertained through linkage with pathology databases; Surveillance, Epidemiology, and End Results programs; and state tumor registries. PARTICIPANTS: 1,010,515 women 40 years of age and older who had at least 1 mammogram between 1996 and 2002; 17,558 of these women had diagnosed breast cancer. MEASUREMENTS: Patterns of mammography and the probability of inadequate mammography screening were examined. The authors evaluated whether overall and advanced cancer rates were similar across racial and ethnic groups and whether these rates were affected by the use of mammography. RESULTS: African-American, Hispanic, Asian, and Native American women were more likely than white women to have received inadequate mammographic screening (relative risk, 1.2 [95% CI, 1.2 to 1.2], 1.3 [CI, 1.2 to 1.3], 1.4 [CI, 1.3 to 1.4], and 1.2 [CI, 1.1 to 1.2] respectively). African-American women were more likely than white, Asian, and Native American women to have large, advanced-stage, high-grade, and lymph node-positive tumors of the breast. The observed differences in advanced cancer rates between African American and white women were attenuated or eliminated after the cohort was stratified by screening history. Among women who were previously screened at intervals of 4 to 41 months, African-American women were no more likely to have large, advanced-stage tumors or lymph node involvement than white women with the same screening history. African-American women had higher rates of high-grade tumors than white women regardless of screening history. The lower rates of advanced cancer among Asian and Native American women persisted when the cohort was stratified by mammography history. LIMITATIONS: Results are based on a cohort of women who had received mammographic evaluations. CONCLUSIONS: African-American women are less likely to receive adequate mammographic screening than white women, which may explain the higher prevalence of advanced breast tumors among African-American women. Tumor characteristics may also contribute to differences in cancer outcomes because African-American women have higher-grade tumors than white women regardless of screening. These results suggest that adherence to recommended mammography screening intervals may reduce breast cancer mortality rates.
