Applying the Hornik & Woolf Approach to Identify Messaging Themes and Improve COVID-19 Vaccine Confidence Among Federally Qualified Health Centers' Workforce in Wisconsin.

The Federally Qualified Health Centers (FQHCs) in Wisconsin serve the most under-resourced communities in the state and are trusted sources in local communities. Although healthcare workers can be leveraged to champion COVID-19 vaccines, existing vaccine hesitancy among the FQHC workforce itself calls for research to identify promising messaging themes that can boost their vaccine confidence. In spring 2021, through a partnership with the Wisconsin Primary Health Association, we took a community-engaged approach to develop and field a survey including 46 beliefs (Ms = 1.36-4.25, SDs = 0.81-1.46, all on 5-point Likert scales) among employees of 10 out of the 17 FQHCs in Wisconsin. In total, 347 clinical team members and 349 non-clinical staff members (a) indicated their levels of (dis)agreement with all 46 belief items and (b) reported vaccine acceptance (dichotomized, acceptance = 77.6%) as well as recommendation intentions (dichotomized, yes = 73.9%). We carried out the Hornik & Woolf analyses in a multilevel logistic regression framework with bootstrapping to rank order all beliefs, segmented by subgroup and behavioral outcome. Our results suggest that communication-based interventions should promote beliefs such as those related to perceived safety and efficacy, rather than normative pressure from peers, while aiming to reduce doubts about information withholding and manipulation, the safety of the mRNA technology, the approval process, and "unnatural" ingredients in the vaccines. Subgroup-specific belief rankings are also provided. This study demonstrates the usefulness of incorporating the H&W approach into community-engaged research with local healthcare systems to improve health messaging for vaccine promotion.

Patient and Provider Perceptions About Communication After Bariatric Surgery: A Qualitative Analysis.

INTRODUCTION: Communication between patients and providers can strongly influence patient behavior after surgery. The objective of this study was to assess patient and provider perceptions of how communication affected weight-related behaviors after bariatric surgery. MATERIALS AND METHODS: Semistructured interviews with bariatric surgery patients and providers were conducted from April-November 2020. Patients who had Medicaid within 3 y of surgery were defined as socioeconomically disadvantaged. Interview guides were derived from Andersen's Behavioral Model of Health Services and Torain's Framework for Surgical Disparities. Participants described postoperative experiences regarding diet, physical activity, and follow-up care. A codebook was developed deductively based on the two theories. Directed content analysis identified themes pertaining to patient-provider communication. RESULTS: Forty-five participants were interviewed, including 24 patients (83% female; 79% White), six primary care providers, four health psychologists, five registered dietitians, and six bariatric surgeons. Four themes regarding communication emerged: (1) Patients experiencing weight regain did not want to follow-up with providers to discuss their weight; (2) Patients from socioeconomically disadvantaged backgrounds had less trust and required more rapport-building from providers to enhance trust; (3) Patients felt that providers did not get to know them personally, which was perceived as a lack of personalized communication; and (4) Providers often changed their language to be simpler, so patients could understand them. CONCLUSIONS: Patient-provider communication after bariatric surgery is essential, but perceptions about the elements of communication differ between patients and providers. Reassuring patients who have attained less weight loss than expected and establishing trust with socioeconomically vulnerable patients could strengthen care after bariatric surgery.

Adapting and Testing the Care Partner Hospital Assessment Tool for Use in Dementia Care: Protocol for a 2 Sequential Phase Study.

BACKGROUND: Research and policy demonstrate the value of and need for systematically identifying and preparing care partners for their caregiving responsibilities while their family member or friend living with dementia is hospitalized. The Care Partner Hospital Assessment Tool (CHAT) has undergone content and face validation and has been endorsed as appropriate by clinicians to facilitate the timely identification and preparation of care partners of older adult patients during their hospitalization. However, the CHAT has not yet been adapted or prospectively evaluated for use with care partners of hospitalized people living with dementia. Adapting and testing the CHAT via a pilot study will provide the necessary evidence to optimize feasibility and enable future efficacy trials. OBJECTIVE: The purpose of this paper is to describe the study protocol for the adaptation and testing of the CHAT for use among care partners of hospitalized people living with dementia to better prepare them for their caregiving responsibilities after hospital discharge. METHODS: Our protocol is based on the National Institutes of Health Stage Model and consists of 2 sequential phases, including formative research and the main trial. In phase 1, we will use a participatory human-centered design process that incorporates people living with dementia and their care partners, health care administrators, and clinicians to adapt the CHAT for dementia care (ie, the Dementia CHAT [D-CHAT]; stage IA). In phase 2, we will partner with a large academic medical system to complete a pilot randomized controlled trial to examine the feasibility and estimate the size of the effect of the D-CHAT on care partners' preparedness for caregiving (stage IB). We anticipate this study to take approximately 60 months to complete, from study start-up procedures to dissemination. The 2 phases will take place between December 1, 2022, and November 30, 2027. RESULTS: The study protocol will yield (1) a converged-upon, ready-for-feasibility testing D-CHAT; (2) descriptive and feasibility characteristics of delivering the D-CHAT; and (3) effect size estimates of the D-CHAT on care partner preparedness. We anticipate that the resultant D-CHAT will provide clinicians with guidance on how to identify and better prepare care partners for hospitalized people living with dementia. In turn, care partners will feel equipped to fulfill caregiving roles for their family members or friends living with dementia. CONCLUSIONS: The expected results of this study are to favorably impact hospital-based care processes and outcomes for people living with dementia and their care partners and to elucidate the essential caregiving role that so many care partners of people living with dementia assume.

Insights into measuring health disparities using electronic health records from a statewide network of health systems: A case study.

Within Wisconsin, our residents experience some of the worst health disparities in the nation. Public reporting on disparities in the quality of care is important to achieving accountability for reducing disparities over time and has been associated with improvements in care. Disparities reporting using statewide electronic health records (EHR) data would allow efficient and regular reporting, but there are significant challenges with missing data and data harmonization. We report our experience in creating a statewide, centralized EHR data repository to support health systems in reducing health disparities through public reporting. We partnered with the Wisconsin Collaborative for Healthcare Quality (the "Collaborative"), which houses patient-level EHR data from 25 health systems including validated metrics of healthcare quality. We undertook a detailed assessment of potential disparity indicators (race and ethnicity, insurance status and type, and geographic disparity). Challenges for each indicator are described, with solutions encompassing internal (health system) harmonization, central (Collaborative) harmonization, and centralized data processing. Key lessons include engaging health systems in identifying disparity indicators, aligning with system priorities, measuring indicators already collected in the EHR to minimize burden, and facilitating workgroups with health systems to build relationships, improve data collection, and develop initiatives to address disparities in healthcare.

Impact of COVID-19 on the Postoperative Bariatric Surgery Patient Experience.

OBJECTIVE: To characterize patient and provider perceptions of the impact of coronavirus disease 2019 (COVID-19) on weight loss following bariatric surgery. BACKGROUND: COVID-19 has disrupted routines and healthcare throughout the United States, but its impact on bariatric surgery patients' postoperative experience is unknown. METHODS: Semistructured interviews with bariatric surgery patients, primary care providers, and health psychologists were conducted from April to November 2020. As part of a secondary analysis, patients and providers described how the COVID-19 pandemic affected the postoperative experience within 3 domains: dietary habits, physical activity, and follow-up care. Interview guides were created from 2 conceptual models: Torain's Surgical Disparities Model and Andersen's Behavioral Model of Health Services Use. Study team members derived codes, which were grouped into themes using conventional content analysis. RESULTS: Thirty-four participants were interviewed: 24 patients (12 Roux-en-Y gastric bypass and 12 sleeve gastrectomy), 6 primary care providers, and 4 health psychologists. Patients were predominately female (83%) and White (79%). Providers were predominately female (90%) and White (100%). COVID-19 affected the postoperative bariatric surgery patient experience via 3 mechanisms: (1) it disrupted dietary and physical activity routines due to facility closures and fear of COVID-19 exposure; (2) it required patients to transition their follow-up care to telemedicine delivery; and (3) it increased stress due to financial and psychosocial challenges. CONCLUSIONS: COVID-19 has exacerbated patient vulnerability. The pandemic is not over, thus bariatric surgery patients need ongoing support to access mental health professionals, develop new physical activity routines, and counteract increased food insecurity.

Socioeconomic disparities and bariatric surgery outcomes: A qualitative analysis.

BACKGROUND: Disparities in socioeconomic status (SES) have been associated with less weight loss after bariatric surgery. The objective of this study was to identify socioeconomic barriers to weight loss after bariatric surgery. METHODS: We performed semi-structured interviews with bariatric surgery patients and providers from April-November 2020. Participants were asked to describe their post-operative experiences regarding dietary habits, physical activity, and follow-up care. Interview data were coded using Directed Content Analysis based on domains in Andersen's Behavioral Model of Health Services Use and Torain's Surgical Disparities Model. RESULTS: 24 patients (median of 4.1 years post-operatively; mean age 50.6 ± 10.7 years; 12 bypass and 12 sleeve; 83% female) and 21 providers (6 bariatric surgeons, 5 registered dietitians, 4 health psychologists, and 6 primary care providers) were interviewed. Barriers to weight loss included: 1) challenging employment situations; 2) limited income; 3) unreliable transportation; 4) unsafe/inconvenient neighborhoods; and 5) limited health literacy. CONCLUSIONS: Interventions targeting socioeconomic barriers to weight loss are needed to support patients, particularly those who are socioeconomically disadvantaged.

Identifying Substantial Racial and Ethnic Disparities in Health Outcomes and Care in Wisconsin Using Electronic Health Record Data.

BACKGROUND: Our goal was to identify racial and ethnic disparities in health outcome and care measures in Wisconsin. METHODS: We used electronic health record data from 25 health systems submitting to the Wisconsin Collaborative for Healthcare Quality to identify disparities in measures, including vaccinations, screenings, risk factors for chronic disease, and chronic disease management. RESULTS: American Indian/Alaska Native and Black populations experienced substantial disparities across multiple measures. Asian/Pacific Islander, Hispanic/Latino, and White populations experienced substantial disparities for 2 measures each. DISCUSSION: Reducing health disparities is a statewide imperative. Root causes of health disparities, such as systemic racism and socioeconomic factors, should be addressed for groups experiencing multiple disparities, with focused efforts on selected measures when indicated.

Training needs of investigators and research team members to improve inclusivity in clinical and translational research participation.

Despite increasing attention to the importance of diverse research participants, success across the translational research spectrum remains limited. To assess investigator and research team training needs, we conducted a web-based survey exploring barriers in knowledge and practice. Respondents (n = 279) included those affiliated with the University of Wisconsin Institute for Clinical and Translational Research (ICTR). Although all respondents reported an abstract belief in the importance of diversity, factors associated with higher levels of best practices knowledge and implementation included: (1) use of federal funding; (2) having fewer years of experience; (3) recruiting healthy participants; and (4) having recruitment training.

Attitudes toward advance care planning among persons with dementia and their caregivers.

OBJECTIVES: To examine factors that influence decision-making, preferences, and plans related to advance care planning (ACP) and end-of-life care among persons with dementia and their caregivers, and examine how these may differ by race. DESIGN: Cross-sectional survey. SETTING: 13 geographically dispersed Alzheimer's Disease Centers across the United States. PARTICIPANTS: 431 racially diverse caregivers of persons with dementia. MEASUREMENTS: Survey on "Care Planning for Individuals with Dementia." RESULTS: The respondents were knowledgeable about dementia and hospice care, indicated the person with dementia would want comfort care at the end stage of illness, and reported high levels of both legal ACP (e.g., living will; 87%) and informal ACP discussions (79%) for the person with dementia. However, notable racial differences were present. Relative to white persons with dementia, African American persons with dementia were reported to have a lower preference for comfort care (81% vs. 58%) and lower rates of completion of legal ACP (89% vs. 73%). Racial differences in ACP and care preferences were also reflected in geographic differences. Additionally, African American study partners had a lower level of knowledge about dementia and reported a greater influence of religious/spiritual beliefs on the desired types of medical treatments. Notably, all respondents indicated that more information about the stages of dementia and end-of-life health care options would be helpful. CONCLUSIONS: Educational programs may be useful in reducing racial differences in attitudes towards ACP. These programs could focus on the clinical course of dementia and issues related to end-of-life care, including the importance of ACP.

Barriers and Strategies for Recruitment of Racial and Ethnic Minorities: Perspectives from Neurological Clinical Research Coordinators.

INTRODUCTION: Randomized controlled trials (RCTs) are the gold standard within evidence-based research. Low participant accrual rates, especially of underrepresented groups (e.g., racial-ethnic minorities), may jeopardize clinical studies' viability and strength of findings. Research has begun to unweave clinical trial mechanics, including the roles of clinical research coordinators, to improve trial participation rates. METHODS: Two semi-structured focus groups were conducted with a purposive sample of 29 clinical research coordinators (CRCs) at consecutive international stroke conferences in 2013 and 2014 to gain in-depth understanding of coordinator-level barriers to racial-ethnic minority recruitment and retention into neurological trials. Coded transcripts were used to create themes to define concepts, identify associations, summarize findings, and posit explanations. RESULTS: Barriers related to translation, literacy, family composition, and severity of medical diagnosis were identified. Potential strategies included a focus on developing personal relationships with patients, community and patient education, centralized clinical trial administrative systems, and competency focused training and education for CRCs. CONCLUSION: Patient level barriers to clinical trial recruitment are well documented. Less is known about barriers facing CRCs. Further identification of how and when barriers manifest and the effectiveness of strategies to improve CRCs recruitment efforts is warranted.

Age-Related Changes in BOLD Activation Pattern in Phonemic Fluency Paradigm: An Investigation of Activation, Functional Connectivity and Psychophysiological Interactions.

Healthy aging is associated with decline of cognitive functions. However, even before those declines become noticeable, the neural architecture underlying those mechanisms has undergone considerable restructuring and reorganization. During performance of a cognitive task, not only have the task-relevant networks demonstrated reorganization with aging, which occurs primarily by recruitment of additional areas to preserve performance, but the task-irrelevant network of the "default-mode" network (DMN), which is normally deactivated during task performance, has also consistently shown reduction of this deactivation with aging. Here, we revisited those age-related changes in task-relevant (i.e., language system) and task-irrelevant (i.e., DMN) systems with a language production paradigm in terms of task-induced activation/deactivation, functional connectivity, and context-dependent correlations between the two systems. Our task fMRI data demonstrated a late increase in cortical recruitment in terms of extent of activation, only observable in our older healthy adult group, when compared to the younger healthy adult group, with recruitment of the contralateral hemisphere, but also other regions from the network previously underutilized. Our middle-aged individuals, when compared to the younger healthy adult group, presented lower levels of activation intensity and connectivity strength, with no recruitment of additional regions, possibly reflecting an initial, uncompensated, network decline. In contrast, the DMN presented a gradual decrease in deactivation intensity and deactivation extent (i.e., low in the middle-aged, and lower in the old) and similar gradual reduction of functional connectivity within the network, with no compensation. The patterns of age-related changes in the task-relevant system and DMN are incongruent with the previously suggested notion of anti-correlation of the two systems. The context-dependent correlation by psycho-physiological interaction (PPI) analysis demonstrated an independence of these two systems, with the onset of task not influencing the correlation between the two systems. Our results suggest that the language network and the DMN may be non-dependent systems, potentially correlated through the re-allocation of cortical resources, and that aging may affect those two systems differently.

DTI measures track and predict motor function outcomes in stroke rehabilitation utilizing BCI technology.

Tracking and predicting motor outcomes is important in determining effective stroke rehabilitation strategies. Diffusion tensor imaging (DTI) allows for evaluation of the underlying structural integrity of brain white matter tracts and may serve as a potential biomarker for tracking and predicting motor recovery. In this study, we examined the longitudinal relationship between DTI measures of the posterior limb of the internal capsule (PLIC) and upper-limb motor outcomes in 13 stroke patients (median 20-month post-stroke) who completed up to 15 sessions of intervention using brain-computer interface (BCI) technology. Patients' upper-limb motor outcomes and PLIC DTI measures including fractional anisotropy (FA), axial diffusivity (AD), radial diffusivity (RD), and mean diffusivity (MD) were assessed longitudinally at four time points: pre-, mid-, immediately post- and 1-month-post intervention. DTI measures and ratios of each DTI measure comparing the ipsilesional and contralesional PLIC were correlated with patients' motor outcomes to examine the relationship between structural integrity of the PLIC and patients' motor recovery. We found that lower diffusivity and higher FA values of the ipsilesional PLIC were significantly correlated with better upper-limb motor function. Baseline DTI ratios were significantly correlated with motor outcomes measured immediately post and 1-month-post BCI interventions. A few patients achieved improvements in motor recovery meeting the minimum clinically important difference (MCID). These findings suggest that upper-limb motor recovery in stroke patients receiving BCI interventions relates to the microstructural status of the PLIC. Lower diffusivity and higher FA measures of the ipsilesional PLIC contribute toward better motor recovery in the stroke-affected upper-limb. DTI-derived measures may be a clinically useful biomarker in tracking and predicting motor recovery in stroke patients receiving BCI interventions.

Characterizing relationships of DTI, fMRI, and motor recovery in stroke rehabilitation utilizing brain-computer interface technology.

The relationship of the structural integrity of white matter tracts and cortical activity to motor functional outcomes in stroke patients is of particular interest in understanding mechanisms of brain structural and functional changes while recovering from stroke. This study aims to probe these underlying mechanisms using diffusion tensor imaging (DTI) and fMRI measures. We examined the structural integrity of the posterior limb of the internal capsule (PLIC) using DTI and corticomotor activity using motor-task fMRI in stroke patients who completed up to 15 sessions of rehabilitation therapy using Brain-Computer Interface (BCI) technology. We hypothesized that (1) the structural integrity of PLIC and corticomotor activity are affected by stroke; (2) changes in structural integrity and corticomotor activity following BCI intervention are related to motor recovery; (3) there is a potential relationship between structural integrity and corticomotor activity. We found that (1) the ipsilesional PLIC showed significantly decreased fractional anisotropy (FA) values when compared to the contralesional PLIC; (2) lower ipsilesional PLIC-FA values were significantly associated with worse motor outcomes (i.e., ipsilesional PLIC-FA and motor outcomes were positively correlated.); (3) lower ipsilesional PLIC-FA values were significantly associated with greater ipsilesional corticomotor activity during impaired-finger-tapping-task fMRI (i.e., ipsilesional PLIC-FA and ipsilesional corticomotor activity were negatively correlated), with an overall bilateral pattern of corticomotor activity observed; and (4) baseline FA values predicted motor recovery assessed after BCI intervention. These findings suggest that (1) greater vs. lesser microstructural integrity of the ipsilesional PLIC may contribute toward better vs. poor motor recovery respectively in the stroke-affected limb and demand lesser vs. greater cortical activity respectively from the ipsilesional motor cortex; and that (2) PLIC-FA is a promising biomarker in tracking and predicting motor functional recovery in stroke patients receiving BCI intervention.

Patterns of research utilization among Certified Hand Therapists.

STUDY DESIGN: Mixed methods, cross-sectional. INTRODUCTION: Nearly 30% of Certified Hand Therapists rarely or never use research findings when treating carpal tunnel syndrome. PURPOSE OF THE STUDY: To identify groups of CHTs with common research utilization patterns. METHODS: National randomized mail survey of 600 CHTs (n = 308, RR = 55%). Latent class and thematic analysis of eight questions assessing research use and beliefs. RESULTS: Four groups of CHT research users were identified: Analytic (n = 135, 45%); Skeptic (n = 65, 22%); Pragmatic (n = 53, 18%); and Traditional (n = 46, 15%). Highest research use was reported among Analytics and Pragmatics although Skeptics willingly relied on research evidence when it contradicted other sources of knowledge. Age, not experience or population density, was a significant covariate of group membership. CONCLUSIONS: Empowering CHTs to use research findings by increased understanding of their group membership, and understanding others' groups, may increase progress toward evidence-based practice.
