Indiana University-Purdue University Indianapolis (IUPUI) / Compared to people who are White and have high socioeconomic status (SES), those who are Black and have low SES are more likely to receive suboptimal pain care. One potential contributor to these disparities is biased provider decision-making—there is compelling evidence that providers are influenced by patient race and SES when making pain treatment decisions. According to the dual process model, people are more likely to be influenced by demographic stereotypes, including implicit beliefs, when they are under high cognitive load (i.e., mental workload). One stereotype belief relevant to pain care is that Black and low SES people are more pain tolerant. Aligned with the dual process model, providers who are under high cognitive load and have strong implicit beliefs that Black and low SES people are more pain tolerant may be particularly likely to recommend fewer pain treatments to them. To test this hypothesis, I recruited physician residents and fellows (n=120) to make pain treatment decisions for 12 computer-simulated patients with back pain that varied by race (Black/White) and SES (low/high). Half of the providers were randomized to the high cognitive load group in which they were interrupted during the decision task to make conversions involving hypertension medications for another patient. Remaining providers completed the task without being interrupted. Providers’ implicit beliefs about race and SES differences in pain tolerance were measured with two separate Implicit Association Tests (IATs). Multilevel modeling indicated that providers recommended stronger medications to low than high SES patients (OR=.68, p=.03). There was also a significant interaction between patient SES and cognitive load (OR=-.56, p=.05) and a trending interaction between patient race and cognitive load (OR=1.7, p=.07). Under low cognitive load, providers recommended more pain treatments to high SES (vs. low SES) and Black (vs. White) patients, but under high cognitive load, providers recommended more pain treatments to low SES (vs. high SES) patients and equivalent treatment to Black and White patients. There were no three-way interactions between patient demographics (race or SES), cognitive load, and providers’ implicit beliefs (race-pain or SES-pain IAT scores). However, there was a trending interaction between patient race and race-pain IAT scores (OR=2.56, p=.09). Providers with stronger implicit beliefs that White people are pain sensitive and Black people are pain tolerant recommended more pain treatments to White patients and fewer pain treatments to Black patients. Lastly, there was a trending effect that providers with stronger implicit beliefs that high SES people are pain sensitive and low SES people are pain tolerant recommended stronger medications in general (OR=13.03, p=.07). Results support that provider cognitive load is clinically relevant and impacts clinical decision-making for chronic pain for racially and socioeconomically diverse patients. Future studies are needed to further understand the impact of cognitive load on providers’ pain care decisions, which may inform evidence-based interventions to improve pain care and reduce disparities.

In the United States, low-income, ethnic/racial minorities and rural populations are at increased risk for poorer health outcomes compared to higher income, non-minorities, and urban populations. Two key determinants that influence rural health disparities are health literacy and social capital. Health literacy can be described as an individual-level factor and defined as, "the degree to which individuals have the capacity to obtain, process, and understand the basic health information and services needed to make appropriate health decisions." Social capital is a concept that accounts for the role of collective social functioning and has been defined as, "the features of social structures, such as levels of interpersonal trust and norms of reciprocity and mutual aid" which act as resources for individuals to facilitate collective action." The overarching goal of this research is to explore factors influencing health disparities, including health literacy, social capital in two rural regions of Virginia. The first study is embedded in Talking Health, a larger 2-arm RCT targeting adults in rural Southwest Virginia and examined participants' perceptions of and satisfaction with components of a behavioral intervention designed using health literacy concepts to decrease sugary beverage intake in rural, low-health literacy participants. The second study is also embedded in the Talking Health trial, yet focused on the maintenance of behavior 12-months after the intervention concluded. Guided by RE-AIM, this study examined the reach, effectiveness and implementation of a 12-month randomized extended care intervention aimed at enhancing long-term maintenance of behavior change and study retention when compared to a control condition. The last study is part of a larger telephone surveillance survey conducted in the Dan River Region located in south central Virginia. This study described current levels of social capital in the Dan River Region and examined the influence of social capital on FV consumption, physical activity, sugary beverage intake and BMI on a sample of rural and urban adults. / Ph.

Purpose: Hispanic or Latino older adults in the US are 1.5 times more likely to have Alzheimer’s and related dementias (ADRD) than white older adults. Nearly one third of all skilled home health (HH) patients and nearly one half of hospice patients have ADRD diagnoses. In ADRD’s long trajectory of decline, patient care transitions bring risks for poor outcomes. Minoritized patients are at high risk for live discharge from hospice, but little is known about those who transition from hospice to skilled HH, the fastest-growing long-term care setting in the US. Aims: to determine demographic and diagnostic variables among patients with ADRD who transition from hospice to skilled HH. Methods: We used Medicare claims data and descriptive statistics including Chi-Square to determine demographic differences in frequency of care transitions from hospice to skilled HH for (a) older adults with ADRD and (b) older adults with co-occurring ADRD and cardiovascular disease (CVD). Results: In N = 272,323 hospice episodes, we found that Hispanic or Latino older adults with co-occurring ADRD and CVD had significantly higher rates of care transitions from hospice to skilled HH (P=0.037) than other racial and ethnic groups with both diagnoses. Conclusions: This is the first study to our knowledge that provides evidence on disparities in care transitions from hospice to skilled HH for Hispanic or Latino older adults with ADRD and CVD. Multiple factors may impact this result. Implications include policy change and greater coordination across systems of care, with specific attention to health equity.
