Towards a shared understanding of the learning health system in a large academic-based health system: A qualitative analysis.

Healthcare delivery is currently undergoing major structural reform, and the Learning Health System (LHS) has been proposed as an aspirational model to guide healthcare transformation. As efforts to build LHS take considerable investment from health systems, it is critical to understand their leaders' perspectives on the rationale for pursuing an LHS and the potential benefits for doing so. This paper describes the qualitative analysis of semi-structured interviews (n = 17) with health system leaders about their general perceptions of the LHS, description of key attributes and potential benefits, and perception of barriers to and facilitators for advancing the model. Participants universally endorsed the goal of the local health system aspiring to become an LHS. Participants identified many recognized attributes of LHS, though they emphasized unique attributes and potential benefits. There was also heterogeneity in participants' views on what to prioritize, how to structure the local LHS within existing initiatives, and how new initiatives should be implemented. Improving conceptual clarity of attributes of the LHS would improve its potential in guiding future reform.

Social Determinants of Health and Cardiologist Involvement in the Care of Adults Hospitalized for Heart Failure.

Importance: Involvement of a cardiologist in the care of adults during a hospitalization for heart failure (HF) is associated with reduced rates of in-hospital mortality and hospital readmission. However, not all patients see a cardiologist when they are hospitalized for HF. Objective: To determine whether social determinants of health (SDOH) are associated with cardiologist involvement in the management of adults hospitalized for HF. Design, Setting, and Participants: This retrospective cohort study used data from the Reasons for Geographic and Racial Difference in Stroke (REGARDS) cohort. Participants included adults who experienced an adjudicated hospitalization for HF between 2009 and 2017 in all 48 contiguous states in the US. Data analysis was performed from November 2022 to January 2023. Exposures: A total of 9 candidate SDOH, aligned with the Healthy People 2030 conceptual model, were examined: Black race, social isolation, social network and/or caregiver availability, educational attainment less than high school, annual household income less than $35 000, living in rural area, living in a zip code with high poverty, living in a Health Professional Shortage Area, and living in a state with poor public health infrastructure. Main Outcomes and Measures: The primary outcome was cardiologist involvement, defined as involvement of a cardiologist as the primary responsible clinician or as a consultant. Bivariate associations between each SDOH and cardiologist involvement were examined using Poisson regression with robust SEs. Results: The study included 1000 participants (median [IQR] age, 77.8 [71.5-84.0] years; 479 women [47.9%]; 414 Black individuals [41.4%]; and 492 of 876 with low income [56.2%]) hospitalized at 549 unique US hospitals. Low annual household income (<$35 000) was the only SDOH with a statistically significant association with cardiologist involvement (relative risk, 0.88; 95% CI, 0.82-0.95). In a multivariable analysis adjusting for age, race, sex, HF characteristics, comorbidities, and hospital characteristics, low income remained inversely associated with cardiologist involvement (relative risk, 0.89; 95% CI, 0.82-0.97). Conclusions and Relevance: This cohort study found that adults with low household income were 11% less likely than adults with higher incomes to have a cardiologist involved in their care during a hospitalization for HF. These findings suggest that socioeconomic status may bias the care provided to patients hospitalized for HF.

Myocardial infarction and physical function: the REasons for Geographic And Racial Differences in Stroke prospective cohort study.

Objective: To examine associations between myocardial infarction (MI) and multiple physical function metrics. Methods: Among participants aged ≥45 years in the REasons for Geographic And Racial Differences in Stroke prospective cohort study, instrumental activities of daily living (IADL), activities of daily living (ADL), gait speed, chair stands, and Short Form-12 physical component summary (PCS) were assessed after approximately 10 years of follow-up. We examined associations between MI and physical function (no MI [n = 9,472], adjudicated MI during follow-up [n = 288, median 4.7 years prior to function assessment], history of MI at baseline [n = 745], history of MI at baseline and adjudicated MI during follow-up [n = 70, median of 6.7 years prior to function assessment]). Models were adjusted for sociodemographic characteristics, health behaviours, depressive symptoms, cognitive impairment, body mass index, diabetes, hypertension, and urinary albumin to creatinine ratio. We examined subgroups defined by age, gender, and race. Results: The average age at baseline was 62 years old, 56% were women, and 35% Black. MI was significantly associated with worse IADL and ADL scores, IADL dependency, chair stands, and PCS, but not ADL dependency or gait speed. For example, compared to participants without MI, IADL scores (possible range 0-14, higher score represents worse function) were greater for participants with MI during follow-up (difference: 0.37 [95% CI 0.16, 0.59]), MI at baseline (0.26 [95% CI 0.12, 0.41]), and MI at baseline and follow-up (0.71 [95% CI 0.15, 1.26]), p < 0.001. Associations tended to be greater in magnitude among participants who were women and particularly Black women. Conclusion: MI was associated with various measures of physical function. These decrements in function associated with MI may be preventable or treatable.

Social Determinants of Health and Cardiologist Involvement in the Care of Adults Hospitalized for Heart Failure.

Introduction: The involvement of a cardiologist in the care of adults during a hospitalization for heart failure (HF) is associated with reduced rates of in-hospital mortality and hospital readmission. However, not all patients see a cardiologist when they are hospitalized for HF. Since reasons for this are not entirely clear, we sought to determine whether social determinants of health (SDOH) are associated with cardiologist involvement in the management of adults hospitalized for HF. We hypothesized that SDOH would be inversely associated with cardiologist involvement in the care of adults hospitalized for HF. Methods: We included adult participants from the national REasons for Geographic And Racial Difference in Stroke (REGARDS) cohort, who experienced an adjudicated hospitalization for HF between 2009 and 2017. We excluded participants who were hospitalized at institutions that lacked cardiology services (n=246). We examined nine candidate SDOH, which align with the Healthy People 2030 conceptual model: Black race, social isolation (0-1 visits from a family or friend in the past month), social network/caregiver availability (having someone to care for them if ill), educational attainment < high school, annual household income < $35,000, living in rural areas, living in a zip code with high poverty, living in a Health Professional Shortage Area, and residing in a state with poor public health infrastructure. The primary outcome was cardiologist involvement, a binary variable which was defined as involvement of a cardiologist as the primary responsible clinician or as a consultant, collected via chart review. We examined associations between each SDOH and cardiologist involvement using Poisson regression with robust standard errors. Candidate SDOH with statistically significant associations (p<0.10) were retained for multivariable analysis. Potential confounders/covariates for the multivariable analysis included age, race, sex, HF characteristics, comorbidities, and hospital characteristics. Results: We examined 876 participants hospitalized at 549 unique US hospitals. The median age was 77.5 years (IQR 71.0-83.7), 45.9% were female, 41.4% were Black, and 56.2% had low income. Low household income (<$35,000/year) was the only SDOH that had a statistically significant association with cardiologist involvement in a bivariate analysis (RR: 0.88 [95% CI: 0.82-0.95]). After adjusting for potential confounders, low income remained inversely associated (RR: 0.89 [95% CI: 0.82-0.97]). Conclusions: Adults with low household income were 11% less likely to have a cardiologist involved in their care during a hospitalization for HF. This suggests that socioeconomic status may implicitly bias the care provided to patients hospitalized for HF.

A Review of Race and Ethnicity in Hospice and Palliative Medicine Research: Representation Matters.

CONTEXT: Despite documented racial and ethnic disparities in care, there is significant variability in representation, reporting, and analysis of race and ethnic groups in the hospice and palliative medicine (HPM) literature. OBJECTIVES: To evaluate the race and ethnic diversity of study participants and the reporting of race and ethnicity data in HPM research. METHODS: Adult patient and/or caregiver-centered research conducted in the U.S. and published as JPSM Original Articles from January 1, 2015, through December 31, 2019, were identified. Descriptive analyses were used to summarize the frequency of variables related to reporting of race and ethnicity. RESULTS: Of 1253 studies screened, 218 were eligible and reviewed. There were 78 unique race and ethnic group labels. Over 85% of studies included ≥ one non-standard label based on Office of Management and Budget designations. One-quarter of studies lacked an explanation of how race and ethnicity data were collected, and 83% lacked a rationale. Over half did not include race and/or ethnicity in the analysis, and only 14 studies focused on race and/or ethnic health or health disparities. White, Black, Hispanic, Asian, American Indian or Alaska Native, and Native Hawaiian or Other Pacific Islander persons were included in 95%, 71%, 43% 37%,10%, and 4% of studies. In 92% of studies the proportion of White individuals exceeded 57.8%, which is their proportion in the U.S. CONCLUSION: Our findings suggest there are important opportunities to standardize reporting of race and ethnicity, strive for diversity, equity, and inclusion among research participants, and prioritize the study of racial and ethnic disparities in HPM research.

Health Behavior Change Programs in Primary Care and Community Practices for Cardiovascular Disease Prevention and Risk Factor Management Among Midlife and Older Adults: A Scientific Statement From the American Heart Association.

Cardiovascular disease predominates as the leading health burden among middle-aged and older American adults, but progress in improving cardiovascular health remains slow. Comprehensive, evidenced-based behavioral counseling interventions in primary care are a recommended first-line approach for promoting healthy behaviors and preventing poor cardiovascular disease outcomes in adults with cardiovascular risk factors. Assisting patients to adopt and achieve their health promotion goals and arranging follow-up support are critical tenets of the 5A Model for behavior counseling in primary care. These 2 steps in behavior counseling are considered essential to effectively promote meaningful and lasting behavior change for primary cardiovascular disease prevention. However, adoption and implementation of behavioral counseling interventions in clinical settings can be challenging. The purpose of this scientific statement from the American Heart Association is to guide primary health care professional efforts to offer or refer patients for behavioral counseling, beyond what can be done during brief and infrequent office visits. This scientific statement presents evidence of effective behavioral intervention programs that are feasible for adoption in primary care settings for cardiovascular disease prevention and risk management in middle-aged and older adults. Furthermore, examples are provided of resources available to facilitate the widespread adoption and implementation of behavioral intervention programs in primary care or community-based settings and practical approaches to appropriately engage and refer patients to these programs. In addition, current national models that influence translation of evidence-based behavioral counseling in primary care and community settings are described. Finally, this scientific statement highlights opportunities to enhance the delivery of equitable and preventive care that prioritizes effective behavioral counseling of patients with varying levels of cardiovascular disease risk.

Mediterranean Diet Score, Dietary Patterns, and Risk of Sudden Cardiac Death in the REGARDS Study.

Background Sudden cardiac death (SCD) is a common cause of death in the United States. Few previous studies have investigated the associations of diet scores and dietary patterns with risk of SCD. We investigated the associations of the Mediterranean diet score and various dietary patterns with risk of SCD in participants in the REGARDS (Reasons for Geographic and Racial Differences in Stroke) study cohort. Methods and Results Diet was assessed with a food frequency questionnaire administered at baseline in REGARDS. The Mediterranean diet score was derived based on the consumption of specific food groups considered beneficial or detrimental components of that diet. Dietary patterns were derived previously using factor analysis, and adherence to each pattern was scored. SCD events were ascertained through regular contacts. Cox proportional hazards regression was used to examine the risk of SCD events associated with the Mediterranean diet score and adherence to each of the 5 dietary patterns overall and stratifying on history of coronary heart disease at baseline. The analytic sample included 21 069 participants with a mean 9.8±3.8 years of follow-up. The Mediterranean diet score showed a trend toward an inverse association with risk of SCD after multivariable adjustment (hazard ratio [HR] comparing highest with lowest group, 0.74; 95% CI, 0.55-1.01; Ptrend=0.07). There was a trend toward a positive association of the Southern dietary pattern with risk of SCD (HR comparing highest with lowest quartile of adherence, 1.46; 95% CI, 1.02-2.10; Ptrend=0.06). Conclusions In REGARDS participants, we identified trends toward an inverse association of the Mediterranean diet score and a positive association of adherence to the Southern dietary pattern with risk of SCD.

Exploring Culturally Responsive Religious and Spirituality Health Care Communications among African Americans with Advanced Heart Failure, Their Family Caregivers, and Clinicians.

Background: Religion and spirituality (R/S) impact how African Americans (AAs) cope with serious illness, yet are infrequently addressed in patient-clinician communication. Objectives: To explore AAs with advanced heart failure and their family caregivers' (FCGs) preferences about R/S in patient-clinician communication. Methods: An embedded qualitative interview within a parent randomized trial about the role of R/S in the illness experience and in clinician interactions with patients and FCGs in a Southern U.S. state. Transcribed interviews were analyzed using constant comparative analysis to identify emergent themes. Results: AA participants (n = 15) were a mean age of 62 years, were female (40%), and had >high school diploma/GED (87%). AA FCGs (n = 14) were a mean age of 58; were female (93%); had >high school diploma/General Education Development (GED) (93%); and were unemployed (86%). Most (63%) were patients' spouses/partners. All patients and FCGs were Protestant. Participants reported the critical role of R/S in living with illness; however, patients' and FCGs' perspectives related to inclusion of R/S in health care communications differed. Patients' perspectives were as follows: (1) R/S is not discussed in clinical encounters and (2) R/S should be discussed only if patient initiated. FCGs' perspectives about ideal inclusion of R/S represented three main diverging themes: (1) clinicians' R/S communication is not a priority, (2) clinicians should openly acknowledge patients' R/S beliefs, and (3) clinicians should engage in R/S conversations with patients. Conclusion: Key thematic differences about the role of R/S in illness and preferences for incorporating R/S in health care communications reveal important considerations about the need to assess and individualize this aspect of palliative care research and practice.

Perceived Institutional Barriers Among Clinical and Research Professionals: Minority Participation in Oncology Clinical Trials.

PURPOSE: In general, participation rates in cancer clinical trials are very low. However, participation rates are especially low among the socially disadvantaged and racial and ethnic minority groups. These groups have been historically under-represented in cancer clinical trials. Although many patient-related barriers have been studied, institutional factors that are essential for building clinical research infrastructure around the clinical trial enterprise in academic medical centers have been underexplored. MATERIALS AND METHODS: We assessed perspectives of cancer center professional stakeholders on the institutional factors that can potentially influence racial and ethnic minority recruitment for cancer clinical trials. Ninety-one qualitative interviews were conducted at five US cancer centers among four stakeholder groups: cancer center leaders, principal investigators, referring clinicians, and research staff. Qualitative analyses examined response data focused on institutional factors related to minority recruitment for cancer clinical trials. RESULTS: Four prominent themes emerged regarding institutional barriers among clinical and research professionals. (1) There are no existing programs currently being used to recruit or retain minorities to clinical trials. (2) Institutional efforts are needed to increase trial participation and are not specific to potential minority participants. (3) Access to cancer clinical trials and navigation within an Academic Medical Center need to be simplified to better facilitate recruitment of minority patients. (4) Community outreach by cancer centers will increase clinical research awareness in the community. CONCLUSION: Our research highlights the need to address institutional barriers to improve the success of minority recruitment. To increase participation among minority populations, medical centers must address mutable institutional barriers such as setting specific minority recruitment goals for cancer clinical trials, ensuring that cancer clinical trials are accessible, especially to minority patients, and supporting sustained community outreach programs to increase clinical research awareness.

Number of Social Determinants of Health and Fatal and Nonfatal Incident Coronary Heart Disease in the REGARDS Study.

BACKGROUND: Social determinants of health (SDH) are individually associated with incident coronary heart disease (CHD) events. Indices reflecting social deprivation have been developed for population management, but are difficult to operationalize during clinical care. We examined whether a simple count of SDH is associated with fatal incident CHD and nonfatal myocardial infarction (MI). METHODS: We used data from the prospective longitudinal REGARDS cohort study (Reasons for Geographic and Racial Differences in Stroke), a national population-based sample of community-dwelling Black and White adults age ≥45 years recruited from 2003 to 2007. Seven SDH from the 5 Healthy People 2020 domains included social context (Black race, social isolation); education (educational attainment); economic stability (annual household income); neighborhood (living in a zip code with high poverty); and health care (lacking health insurance, living in 1 of the 9 US states with the least public health infrastructure). Outcomes were expert adjudicated fatal incident CHD and nonfatal MI. RESULTS: Of 22 152 participants free of CHD at baseline, 58.8% were women and 42.0% were Black; 20.6% had no SDH, 30.6% had 1, 23.0% had 2, and 25.8% had ≥3. There were 463 fatal incident CHD events and 932 nonfatal MIs over a median of 10.7 years (interquartile range, 6.6 to 12.7). Fewer SDHs were associated with nonfatal MI than with fatal incident CHD. The age-adjusted incidence per 1000 person-years increased with the number of SDH for both fatal incident CHD (0 SDH, 1.30; 1 SDH, 1.44; 2 SDH, 2.05; ≥3 SDH, 2.86) and nonfatal MI (0 SDH, 3.91; 1 SDH, 4.33; ≥2 SDH, 5.44). Compared with those without SDH, crude and fully adjusted hazard ratios for fatal incident CHD among those with ≥3 SDH were 3.00 (95% CI, 2.17 to 4.15) and 1.67 (95% CI, 1.18 to 2.37), respectively; hazard ratios for nonfatal MI among those with ≥2 SDH were 1.57 (95% CI, 1.30 to 1.90) and 1.14 (95% CI, 0.93 to 1.41), respectively. CONCLUSIONS: A greater burden of SDH was associated with a graded increase in risk of incident CHD, with greater magnitude and independent associations for fatal incident CHD. Counting the number of SDHs may be a promising approach that could be incorporated into clinical care to identify individuals at high risk of CHD.
