Community Engagement Alliance (CEAL) Against COVID-19 Disparities: Academic-community partnership to support workforce capacity building among Arizona community health workers

The COVID-19 pandemic has both highlighted and worsened existing health inequities among communities of color and structurally vulnerable populations. Community Health Workers, inclusive of Community Health Representatives (CHW/Rs) have entered the spotlight as essential to COVID-19 prevention and control. To learn about community experiences and perspectives related to COVID-19 and inform CHW/R workforce capacity building efforts, a series of focus groups were conducted with CHW/Rs throughout Arizona at two time points in 2021. Throughout the data collection and analysis process, researchers and community partners engaged in ongoing and open dialogue about what CHW/Rs on the ground were reporting as priority community concerns, needs, and challenges. Thus, CHW/Rs informed the development of culturally and linguistically relevant health education messages, materials, and training for CHW/Rs. In this community case study, we detail the efforts of partnership between a statewide CHW professional association and an academic research team that facilitated rapid decision-making and knowledge sharing to create community-grounded tools and resources supportive of CHW/R workforce capacity building in the context of the COVID-19 pandemic.

An integrated mixed methods approach to clarifying delivery, receipt and potential benefits of CHW-facilitated social support in a health promotion intervention

Background

Social support plays a critical role in physical and emotional health, making it an important component of community health worker (CHW) health promotion interventions. Different types of support operate in different ways, however, and the relationship between the nature of CHW support and the subsequent health benefit for their clients is not well understood.

Methods

This paper describes an integrated mixed methods study of the emotional, informational, appraisal and tangible support CHWs provided to Latinx community members residing in three US-Mexico border communities. Using a cohort (n = 159) from a CHW community-based intervention, we identify and describe four clusters of social support in which participants are characterized by life situations that informed the types of social support provided by the CHW. We examine the association between each cluster and client perceptions of social support over the 6-month intervention.

Results

CHWs provided emotional, appraisal, informational and tangible support depending on the needs of participants. Participants who received higher levels of emotional support from the CHW experienced the greatest post intervention increase in perceived social support.

Conclusions

Study findings suggest that CHWs may be adept at providing non-directive social support based on their interaction with a client rather than a health outcome objective. Health promotion interventions should allow CHWs the flexibility to tailor provision of social support based on their assessment of client needs.

Training Needs of Community Health Workers Facing the COVID-19 Pandemic in Texas: A Cross-Sectional Study

The COVID-19 pandemic has required the professional healthcare workforce not only to adjust methods of delivering care safely but also act as a trusted sources of information during a time of uncertainty and rapid research and discovery. The Community Health Worker COVID-19 Impact Survey is a cross-sectional study developed to better understand the impact of COVID-19 on this sector of the healthcare workforce, including training needs of those working through the pandemic. The survey was distributed in Texas, New Mexico, and Arizona. This study focuses on Texas, and the data presented (n = 693) is a sub-set of qualitative data from the larger survey. Results of the content analysis described in this paper are intended to inform current COVID-19-related CHW training curriculum, in addition to future infectious disease prevention and preparedness response trainings.

Organizational Readiness for Community Health Worker Workforce Integration Among Medicaid Contracted Health Plans and Provider Networks: An Arizona Case Study

Understanding and building organizational capacity for system change and the integration of the Community Health Worker (CHW) workforce within the health scare sector requires a supportive organizational culture among sector leaders and providers. The aim of this mixed-methods study was to assess organizational readiness for CHW workforce integration into Arizona Medicaid health systems and care teams. This collaborative effort was in direct response to emergent state and national CHW workforce policy opportunities, and the shifting health care landscape in Arizona – which merged behavior and physical health. Specifically, and in collaboration with a broad-based, statewide CHW workforce coalition, led by the CHW professional association, we assessed 245 licensed health care professionals with experience working with CHWs and 16 Medicaid-contracted health plan leadership. Our goal was to generate a baseline understanding of the knowledge, attitudes and beliefs these stakeholders held about the integration of CHWs into systems and teams. Our findings demonstrate a high level of organizational readiness and action toward integration of CHWs within the Arizona health care system and care teams. CHWs have emerged as a health care workforce able to enhance the patient experience of care, improve population health, reduce cost of care, and improve the experience of providing care among clinicians and staff.

Establishing voluntary certification of community health workers in Arizona: a policy case study of building a unified workforce

BACKGROUND

Community health workers (CHWs) are widely recognized as essential to addressing disparities in health care delivery and outcomes in US vulnerable populations. In the state of Arizona, the sustainability of the workforce is threatened by low wages, poor job security, and limited opportunities for training and advancement within the profession. CHW voluntary certification offers an avenue to increase the recognition, compensation, training, and standardization of the workforce. However, passing voluntary certification legislation in an anti-regulatory state such as Arizona posed a major challenge that required a robust advocacy effort.

CASE PRESENTATION

In this article, we describe the process of unifying the two major CHW workforces in Arizona, promotoras de salud in US-Mexico border communities and community health representatives (CHRs) serving American Indian communities. Differences in the origins, financing, and even language of the population-served contributed to historically divergent interests between CHRs and promotoras. In order to move forward as a collective workforce, it was imperative to integrate the perspectives of CHRs, who have a regular funding stream and work closely through the Indian Health Services, with those of promotoras, who are more likely to be grant-funded in community-based efforts. As a unified workforce, CHWs were better positioned to gain advocacy support from key health care providers and health insurance companies with policy influence. We seek to elucidate the lessons learned in our process that may be relevant to CHWs representing diverse communities across the US and internationally.

CONCLUSIONS

Legislated voluntary certification provides a pathway for further professionalization of the CHW workforce by establishing a standard definition and set of core competencies. Voluntary certification also provides guidance to organizations in developing appropriate training and job activities, as well as ongoing professional development opportunities. In developing certification with CHWs representing different populations, and in particular Tribal Nations, it is essential to assure that the CHW definition is in alignment with all groups and that the scope of practice reflects CHW roles in both clinic and community-based settings. The Arizona experience underscores the benefits of a flexible approach that leverages existing strengths in organizations and the population served.

Protocol for LINKS (linking individual needs to community and clinical services): a prospective matched observational study of a community health worker community clinical linkage intervention on the U.S.-Mexico border

Background

Latinos are currently the largest and fastest growing racial/ethnic group in the United States and have the lowest rates nationally of regular sources of primary care. The changing demographics of Latino populations have significant implications for the future health of the nation, particularly with respect to chronic disease. Community-based agencies and clinics alike have a long history of engaging community health workers (CHWs) to provide a broad range of tangible and emotional support strategies for Latinos with chronic diseases. In this paper, we present the protocol for a community intervention designed to evaluate the impact of CHWs in a Community-Clinical Linkage model to address chronic disease through innovative utilization of electronic health records (EHRs) and application of mixed methodologies. Linking Individual Needs to Community and Clinical Services (LINKS) is a 3-year, prospective matched observational study designed to examine the feasibility and impact of CHW-led Community-Clinical Linkages in reducing chronic disease risk and promoting emotional well-being among Latinos living in three U.S.-Mexico border communities.

Methods

The primary aim of LINKS is to create Community-Clinical Linkages between three community health centers and their respective county health departments in southern Arizona. Our primary analysis is to examine the impact of the intervention 6 to 12-months post program entry. We will assess chronic disease risk factors documented in the EHRs of participants versus matched non-participants. By using a prospective matched observational study design with EHRs, we have access to numerous potential comparators to evaluate the intervention effects. Secondary analyses include modeling within-group changes of extended research-collected measures. This approach enhances the overall evaluation with rich data on physical and emotional well-being and health behaviors of study participants that EHR systems do not collect in routine clinical practice.

Discussion

The LINKS intervention has practical implications for the development of Community-Clinical Linkage models. The collaborative and participatory approach in LINKS illustrates an innovative evaluation framework utilizing EHRs and mixed methods research-generated data collection.

Trial registration

This study protocol was retrospectively registered, approved, and made available on Clinicaltrials.gov by NCT03787485 as of December 20, 2018.

The border community and immigration stress scale: a preliminary examination of a community responsive measure in two Southwest samples

Understanding contemporary socio-cultural stressors may assist educational, clinical and policy-level health promotion efforts. This study presents descriptive findings on a new measure, the border community and immigration stress scale. The data were from two community surveys as part of community based participatory projects conducted in the Southwestern US border region. This scale includes stressful experiences reflected in extant measures, with new items reflecting heightened local migration pressures and health care barriers. Stressors representing each main domain, including novel ones, were reported with frequency and at high intensity in the predominantly Mexican-descent samples. Total stress was also significantly associated with mental and physical health indicators. The study suggests particularly high health burdens tied to the experience of stressors in the US border region. Further, many of the stressors are also likely relevant for other communities within developed nations also experiencing high levels of migration.

An assessment of wall motion, perfusion and glucose metabolism in recent myocardial infarction: a comparison in patients with and without revascularization

The aim of this study was to compare the extent and severity of wall motion abnormalities, perfusion and glucose metabolism, in recent myocardial infarction in patients with and without revascularization. Forty-nine patients were studied (82% men; mean age 58 years) by using echocardiography, 201Tl single photon emission computed tomography (SPECT) rest and redistribution, and 2-[18F]fluoro-2-deoxy-D-glucose (18F-FDG) SPECT at a mean of 9.2 days (range, 1-24 days) after myocardial infarction. Twenty-seven of the 49 patients underwent revascularization while the other 22 received medical therapy before echocardiography and studies using radionuclides. A contrast angiogram was obtained for each patient. A follow-up echocardiogram at 3 months was obtained for 44 patients. Images were read blindly, using a 17 segment model, with semi-quantitative analysis. In the whole group, the extent of hypokinesia was 15%+/-14 (mean+/-SD); the extent of mild defects was determined as 5%+/-6 by using 201Tl at rest, 6%+/-9 by using 201Tl redistribution, and 4%+/-6 by using 18F-FDG (P<0.0005, echocardiogram/radionuclides). Echocardiography showed that the extent of akinesia-dyskinesia was 16%+/-18 in revascularized patients and 28%+/-18 in non-revascularized patients (P=0.017). With regard to moderate and severe defects, 201Tl rest showed 19%+/-16 and 28%+/-17, respectively (P=0.047); 201Tl redistribution 17%+/-15 and 26%+/-15, respectively (P=0.043); and 18F-FDG 17%+/-13 and 24%+/-15, respectively (NS). In echocardiography, the extent of hypokinetic segments decreased from 16%+/-15 at baseline to 10%+/-11 at 3 months (P=0.045), in revascularized patients. It is concluded that, in recent myocardial infarction, hypokinesia extent on echocardiogram is greater than mild perfusion or metabolic defect extent, reflecting stunning and so the use of radionuclide techniques appear more accurate for defining the extent of myocardial infarction. Non-revascularized patients showed a significantly greater extent of akinesia-dyskinesia and moderate-severe perfusion defects than did revascularized patients, which can be considered a result of therapy. It is suggested that 201Tl rest perfusion be used for the assessment of myocardial infarction soon after revascularization.

[Inflammatory pseudotumor of the maxillary sinus: report of a new case and review of the literature]

A new case of inflammatory pseudotumor (IPT) of the maxillary sinus is presented. The clinical and histological features of this rare entity are discussed. Immunohistochemical studies support a possible myofibroblastic origin. Early diagnosis is important to prevent IPT, classified as a benign disease, from becoming a progressive destructive lesion.

[High-frequency audiometry: variations in auditory thresholds in the premenstrual period]

The hormonal changes that occur during the premenstrual period have been implicated as a causative factor for many psychological and physical symptoms. The present work was undertaken to determine the effect of these hormonal changes on audition. We studied 60 ears from 30 women (20-30 years old) with regular menstrual cycles and no middle/inner ear pathology. We performed audiometries one week before menstruation and one week after it, testing the range of frequencies from 250 to 16,000 Hz. After calculating the mean pre and postmenstrual threshold the results were compared using the paired <<t>>-Student test. We found statistical significant differences in the frequencies 9,000, 10,000 and 11,200 Hz.

Differences in heart transplant physiology according to surgical technique

A new cardiac transplantation technique that preserves the shape of the left atrium and leaves the right atrium intact has been introduced. To compare the new and the standard techniques, we studied cardiac physiology with Doppler echocardiography and catheterization in 26 patients who underwent operation with the standard technique (group A) and I1 who underwent operation with the new technique (group B). Right atrial dimensions were significantly lower in group B (right atrial area index 8.4 +/- 1.5 vs 14.5 +/- 1.9 cm2/m2, p < 0.001), whereas left atrial dimensions were slightly lower (left atrial area index 10.8 +/- 2.0 vs 16.4 +/- 7.0 cm2/m2, p = 0.07). Right atrial contraction, as reflected by peak late tricuspid velocity, was greater in group B (37 +/- 15 vs 30 +/- 10 cm/sec, p < 0.05). The subsequent systolic vena caval flow-velocity integral was also greater in group B at all respiratory phases (inspiration 10.0 +/- 4.0 vs 5.2 +/- 4.0 cm, p < 0.001; expiration 4.8 +/- 1.9 vs 2.9 +/- 1.4 cm, p < 0.001; apnea 5.3 +/- 2.0 vs 2.9 +/- 1.9 cm, p < 0.001) suggesting better atrial relaxation. Filling pressures on the right side of the heart were lower in group B (mean right atrial pressure 5.5 +/- 2.4 vs 6.6 +/- 2.8 mm Hg, p = 0.1; right atrial A wave 6.0 +/- 3.1 vs 8.3 +/- 3.2 mm Hg, p < 0.01; right atrial V wave 6.8 +/- 3.1 vs 9.2 +/- 3.2 mm Hg, p < 0.01; right ventricular end-diastolic pressure 5.6 +/- 3.2 vs 7.3 +/- 2.9 mm Hg, p < 0.05); however, no significant differences were found in left ventricular end-diastolic pressure or cardiac index. We conclude that patients undergoing the new technique exhibit cardiac physiologic improvements. Follow-up study is indicated to ascertain whether this finding implies improved long-term prognosis.

Unreliability of echocardiographic and Doppler indexes in the diagnosis of heart transplant acute rejection

OBJECTIVE

To investigate the value of Doppler echocardiography to diagnose heart transplant acute rejection in both patients submitted to the standard surgical technique (Group A), and to a new technique that preserves the size of the left atrium and leaves the right atrium intact (Group B).

METHODS

122 Doppler echocardiographic studies and endomyocardial biopsies were performed on 27 group A and 11 group B patients. Systolic measurements included left ventricular shortening fraction, left ventricular endsystolic stress and tricuspid ring systolic displacement. Diastolic indexes investigated were left and right ventricle filling and superior vena caval flow parameters.

RESULTS

As expected, right atrium was smaller in group B(p < 0.01). In group A, peak early to late mitral flow velocity increased, as did the rejection grade; whereas in group B it decreased. Pericardial effusion was seen more frequently in group B rejectors (> or = 3) than non-rejectors (63% vs 27%, p < 0.01). Right heart pressures (right ventricular end-diastolic and right atrial mean) were slightly higher for group A and B rejector patients (p < 0.05 when comparing right ventricular end-diastolic pressure in rejector to non-rejector group B patients). Left ventricular isovolumic relaxation time was reduced during subsequent rejection episodes in the same patient, but sensitivity of 15% left ventricular isovolumetric relaxation time reduction for rejection > or = 3 diagnosis was only 22% with a specificity of 73%. No significant intrapatient changes were found in other Doppler-derived systolic or diastolic indexes.

CONCLUSION

Doppler echocardiography does not diagnose heart transplant acute rejection with enough reliability to avoid endomyocardial biopsies.
