Development and Validation of a Stroke Literacy Assessment Test for Community Health Workers.

Community health workers (CHWs) are increasingly being required to perform complex health care activities, especially in community cardiovascular disease and stroke prevention. However, currently, there are no psychometrically validated instruments for assessing CHW competencies in these roles. This article describes the development and validation of the stroke literacy assessment test (SLAT)-pertaining to the Life's Simple Seven (LS7) risk factors for stroke-for evaluating CHWs' competencies in the context of education and training programs. The SLAT was developed using an iterative instrument design protocol, followed by empirically testing the instrument in 68 CHWs from the Columbia University Institute for Training Outreach and Community Health (InTOuCH) in New York. Data collection began in March 2021 and continued through May 2021. The evaluation was based on four types of validity evidence: (a) content validation with expert reviews of items and overall domain, (b) validation on examinee response processes with cognitive interviews, (c) item validation and diagnostic analysis, and (d) validity evidence based on expected directional group differences. In addition, the internal consistency reliability of the total test scores, with the best functioning items, were evaluated. Two such iterative cycles yielded a 34-item, written structured response test that assesses the factual knowledge and application levels of cognition, and demonstrates sufficient validity and reliability (Cronbach's α = .69) for use with CHWs specializing in stroke prevention efforts. The SLAT is a novel, valid, and reliable instrument that contributes to filling a critical gap in rigorous competency assessments for CHWs deployed in chronic disease prevention.

Community Health workers United to Reduce Colorectal cancer and cardiovascular disease among people at Higher risk (CHURCH): study protocol for a randomized controlled trial.

Background: Colorectal cancer (CRC) is the second most lethal cancer in the United States (U.S.) with the highest incidence and mortality rates among African Americans (AAs) compared to other racial groups. Despite these disparities, AAs are the least likely to undergo CRC screening, have precancerous colorectal polys removed, and have CRC detected at stages early enough for curative excision. In addition, compelling evidence links inflammatory dietary patterns to increased CRC and cardiovascular disease risk. Studies show that AA churches can successfully engage in health promotion activities including those related to cancer control. The current study seeks to leverage church-placed Community Health Workers (CHWs) to increase CRC screening and reduce CRC risk. Design and Methods: We aim to (1) increase guideline concordant CRC screening uptake using church-placed CHWs trained in screening with a validated instrument, Brief Intervention using Motivational Interviewing, and Referral to Treatment (SBIRT); and (2) reduce dietary risk factors (inflammatory dietary patterns) linked to CRC. The latter will be addressed by culturally adapting an existing, web-based lifestyle program called Alive!. Using a Hybrid Type 1 Implementation-Effectiveness cluster randomized design, we will randomize 22 AA churches into either the dual intervention arm (CHW-led SBIRT intervention plus Alive!) or a usual care arm comprised of CRC prevention educational pamphlets and a list of CRC screening sites. We will recruit 440 subjects and evaluate the effects of both arms on screening uptake (colonoscopy, fecal DNA) (primary outcome) and dietary inflammation score (secondary outcome) at 6-months follow up, and Life Simple7 (LS7) - a cardiovascular disease (CVD) risk score - at 6 months and 1-year (secondary outcome). Finally, guided by a racism-conscious adaptation of the Consolidated Framework for Implementation Research (CFIR), we will conduct a mixed-methods process evaluation with key stakeholders to understand multi-level influences on CRC screening and CVD risk behaviors. Discussion: Church-placed CHWs are trusted influential connectors between communities and health systems. Studies have shown that these CHWs can successfully implement health prevention protocols in churches, including those related to cancer control, making them potentially important community mediators of CRC screening uptake and CRC/CVD risk reduction.

Cardiovascular Disease and Stroke-Focused Competency Assessment Tools for Community Health Workers in the United States: A Scoping Review.

Cardiovascular disease (CVD) and stroke are major contributors to chronic disease burden in the United States. Despite the high prevalence of stroke, 90% of all stroke events are preventable and can be attributed to seven key modifiable risk factors (MRFs)-high blood pressure (BP), high cholesterol, diabetes mellitus (DM), smoking, obesity, unhealthy diet, and physical inactivity. In the United States, stroke prevention interventions led by community health workers (CHWs) have been proven to be highly effective in preventing the onset of MRFs. We conducted a scoping review of the competency assessment methods used in CVD and stroke-focused CHW training programs. We searched six online databases: PubMed, Cochrane, CINAHL, Embase, Web of Science, and HaPI, from all available years until January 2021. Of the 1,774 initial articles found, we identified 30 eligible articles to be included in the review. Nine of these studies used previously validated instruments, whereas the remaining 21 studies used tools from the training curriculum or independently developed instruments. Only five of these validated tools reported psychometric properties; none of them were designed for the CHW population. Our scoping review of literature revealed that CHW-specific competency assessment methods were limited, with few or no domain-referenced tools on CVD or stroke risk factors that complied with established measurement standards. We conclude that there is an urgent need for the development of a comprehensive and valid assessment instrument in CVD and stroke prevention to evaluate CHW performance and optimize their credibility, representing important first steps toward integrating CHWs into health care systems.

Study protocol for comparing Screening, Brief Intervention, and Referral to Treatment (SBIRT) to referral as usual for depression in African American churches.

BACKGROUND: Depression is a leading cause of disability worldwide. African American adults, compared to White adults, are half as likely to be screened for depression in primary care settings. Disparities in depression screening contribute to poor clinical outcomes, as African Americans with depression are more disabled and sicker longer compared to Whites. African American churches are trusted settings that provide access to supports for depression. Indeed, in the first study of its kind, the investigators found that 20% of adults in African American churches screened positive for depression using the Patient Health Questionnaire-9 (PHQ-9). However, no subjects with a positive screen (PHQ-9 ≥ 10) accepted a treatment referral when offered by research personnel. Community Health Workers, who are trusted paraprofessionals from the target community, may bridge the gap between depression screening and treatment. The investigators have trained and certified 112 Community Health Workers from 45 African American churches in New York City to deliver an evidence-based intervention called Screening, Brief Intervention, and Referral to Treatment (SBIRT). Thus, the aim of the current study is to test the impact of Community Health Worker-delivered depression screening in Black churches on engagement with clinical services. METHODS: Using a hybrid type 1 effectiveness-implementation design, we propose a 2-arm, mixed-methods cluster randomized controlled trial. Church study sites will be randomized to either SBIRT (intervention arm) or referral as usual (usual care arm). This trial will be conducted with 600 church members across 30 churches (300 intervention; 300 usual care). Our primary outcome is treatment engagement, defined as attending a depression-related clinical visit. Secondary outcomes will be changes in Mental Health-Related Quality of Life and depressive symptoms at 3 and 6 months post-screening. Lastly, we will conduct a concurrent, mixed-methods (qualitative-quantitative) process evaluation to assess contextual facilitators and barriers of screening and referral. DISCUSSION: This is the first randomized trial of a church-placed, community health worker-delivered intervention for depression in African American populations. This study may provide a novel and effective approach to increasing depression identification and treatment linkage in economically disadvantaged populations with high depression rates.

Mobile health application for remote oral cancer surveillance.

BACKGROUND: To determine the effectiveness of a mobile phone-based remote oral cancer surveillance program (Oncogrid) connecting primary care dental practitioners and frontline health care workers (FHW) with oral cancer specialists. METHODS: The study population (N = 3,440) included a targeted cohort (n = 2,000) and an opportunistic cohort (n = 1,440) screened by FHW and dental professionals, respectively. The authors compared the screening efficacy in both groups, with specialist diagnosis considered the reference standard. The outcomes measured were lesion detection and capture of interpretable images of the oral cavity. RESULTS: In the targeted cohort, among 51 of 81 (61%) interpretable images, 23 of 51 (45%) of the lesions were confirmed by specialists, while the opportunistic cohort showed 100% concordance with the specialists (106 of 106). Sixty-two of 129 (48%) of the recommended patients underwent biopsy; 1 of 23 (4%) were in the targeted cohort, and 61 of 106 (57%) were in the opportunistic cohort. Ninety percent of the lesions were confirmed to be malignant or potentially malignant. CONCLUSIONS: The mobile health-based approach adopted in this study aided remote early detection of oral cancer by primary care dental practitioners in a resource-constrained setting. Further optimization of this program is required to adopt the system for FHW. Evaluation of its efficacy in a larger population is also warranted. PRACTICAL IMPLICATIONS: The increased efficiency of early detection by dentists, when assisted by a remote mobile health-based approach, is a step toward a more effective oral cancer screening program.
