Patients' Perspectives on the Acceptability and Effectiveness of a Community Health Worker-Led Intervention to Increase Chronic Kidney Disease Knowledge and Screening among Underserved Latine Adults: The CARE 2.0 Study.

In the United States, Chronic Kidney Disease (CKD) affects approximately 1 in 7 adults. Despite its significant impact, CKD awareness, education, and screening are often lacking among underserved Latine populations, leading to poorer health outcomes and higher mortality rates. Various studies highlight the crucial role of Community Health Workers (CHWs) in improving health outcomes within minority communities both domestically and globally. However, there remains a gap in research on the acceptance and effectiveness of CHW-led interventions targeting CKD. This prospective intervention study employed a pre-post quasi-experimental design to evaluate a CHW-led educational program aimed at enhancing CKD knowledge, screening, and monitoring among Latines with low health literacy and English proficiency. CHWs utilized a culturally tailored CKD Flipchart, and 100 underserved patients received the intervention. Feedback from 85 participants who completed post-intervention surveys indicated high satisfaction with the program's relevance and the professionalism of the CHWs. Importantly, 85% expressed a positive intention to seek kidney care following the intervention. Preliminary analysis of medical records before and after the intervention showed improvements in glycemic control (median change = -18.0, p = 0.014) and triglyceride levels (median change = -29.0, p = 0.035), suggesting the program's effectiveness in managing CKD risk factors. These findings highlight the potential of CHW-led interventions to reduce kidney health disparities among underserved communities.

The effect of a multilevel community health worker-led intervention on patient knowledge and receipt of precision medicine: Updated findings from a randomized clinical trial.

1609 Background: Inequitable access to precision medicine limits its impact. To address disparities, we co-developed a 2-part multi-level intervention with community stakeholders, called the Addressing Latinx CANcer Care Equity Study (NCT04843332). The intervention was designed for low-income and Latinx adults with cancer in rural Monterey County, California. We provided annual training for clinicians about testing guidelines and precision medicine disparities. Trained community health workers educated patients about precision medicine and encouraged them to raise the topic with their oncologist. We tested whether the intervention improved patient knowledge and receipt of precision medicine. Methods: Patients with newly diagnosed or recurrent cancer, age ≥ 18 years, able to consent in English or Spanish, and who self-identified as a racial and ethnic minority OR low-income status OR were insured by public or agricultural company insurance OR uninsured and receiving cancer care at Pacific Cancer Care, a rural community oncology practice in Monterey County, were randomized 1:1 to usual care (control group) or usual care augmented with the multi-level intervention for 12 months (intervention group). The primary outcome was whether the multilevel intervention could increase patient knowledge of precision medicine using a validated 6-question survey from the time of enrollment (baseline) to 6 months post-enrollment between groups. A secondary outcome was the receipt of precision medicine. Patients were followed for 12 months. Results: 110 participants were randomized; 70% (n = 67) reported Spanish as their primary language; 81% (n = 89) identified as Hispanic. The median age was 55 years (55.4 ± 14.3, mean± SD); the majority had annual household incomes (USD) ≤ $34,999 (59.0%, n = 46); the majority obtained a high school diploma/GED or less (67.3%, n = 74). Most had gastrointestinal (35.5%, n = 39) and breast (24.5%, n = 27) cancers and were diagnosed with stage 3 or 4 (64.5%, n = 71) disease. Precision medicine knowledge was low at baseline across both the control and intervention groups (23.5 ± 19.3 versus 23.0 ± 17.7, respectively). Intervention group participants had greater precision medicine knowledge at 6 months (39.2 ± 23.0) than control group participants (24.2 ± 20.0) with a greater increase in knowledge over time than control group participants (p < 0.001).More intervention group participants (n=46, 79.3%) received precision medicine testing than control (n=34, 60.7%). Across both groups, 26 of those tested had an actionable mutation. Of those 26, 66.7% (n=6 of 9) in the control group and 94.1% (n=16 of 17) in the intervention group received targeted therapy (p=0.065). Conclusions: CHW-facilitated interventions may reduce disparities in precision medicine cancer care. Clinical trial information: NCT04843332 .

Enhancing sexual health and empowerment among migrant women sex workers: a community health worker-led intervention in Marseille, France.

Given the high infection rate of sexually transmitted infections (STI) among migrant women sex workers (WSWs), it is necessary to understand how to improve prevention, information and care for this vulnerable population. Community health workers (CHWs), by linking community to health services, are positioned to improve health outcomes in migrant communities. This article aims to describe a pilot innovative intervention performed by CHWs to improve sexual health in migrant WSWs. This one-year intervention study used a respondent-driven sampling (RDS) to recruit a representative cohort of migrant WSWs in Marseille, France. Four CHWs were recruited from different communities and participated in all stages of the research. They performed individual and group interventions of prevention, support in care and empowerment. Data on participant characteristics, type of intervention and adherence to the intervention were reported via questionnaires given to participants. Simultaneously, semi-structured interviews and informal interviews of migrant WSW, CHWs and care providers were carried out. A total of 132 migrant WSWs were included in the cohort. Very few of them knew about PrEP (12%) or already used HIV post-exposure treatment (9%). Migrant WSWs were often victims of rape or racism, 15 and 21%, respectively. In two-thirds of cases the level of health literacy was low. Participants suffered from a combination of vulnerability factors: difficulties with access to social rights, food or housing. Only 13% reported having benefited from medical follow-up or assistance by an NGO in the 3 months prior to the program. By 3 months, more than one third of the participants had been tested for HIV (35%) and 63% knew about PrEP. A total retention rate of 70% was reported in the cohort after 6 months. CHWs enabled to improve care access for migrant WSWs by improving the collaboration between care and social actors at a local level. Through these "bring-back-to" interventions for this hard-to-reach population, CHWs enabled an optimization of the care pathway. Our results also highlight the importance of a population-based approach for individual and group support of empowerment interventions in order to strengthen their capacity for action.

Leveling the Research Playing Field: Decolonizing Global Health Research Through Web-Based Platforms.

Global health research has traditionally been rooted in colonialism, with some investigators in high-income countries leading and managing research and investigators in low- and middle-income countries serving as implementing partners. The Community Health Worker-Led Intervention for Vaccine Information and Confidence (CIVIC) Project, conducted in India and led jointly by India- and US-based investigators, leveraged web-based platforms to facilitate a more horizontal, inclusive, and balanced approach to partnerships between researchers and the community. Using web-based platforms to conduct research was found to be an effective strategy to engage researchers at all levels and combat systemic barriers associated with in-person activities such as power, economic, social, and gender dynamics. Connecting online for research meetings created a more equitable environment for community members to engage meaningfully with research. Further, by conducting research through web-based platforms, we found that we were able to strengthen the diversity of participants, provide a space for more marginalized groups to speak up, and minimize logistical barriers to attendance. Harnessing web-based approaches in research provides a pathway toward opportunities to promote equity and contribute to the decolonization of global health spaces.

Effectiveness of a Community Health Worker-Led Intervention on Knowledge, Perception, and Prostate Cancer Screening among Men in Rural Kenya.

Background Globally, an increase in mortality from prostate cancer (PC) remains a big challenge with disparities existing with a slight preponderance among men in low and middle-income countries. Prostate cancer is a leading cause of mortality among men in sub-Saharan Africa. In Kenya, despite the majority of men presenting with advanced prostate cancer for treatment, knowledge and screening for prostate cancer is low. The study aimed to examine the effectiveness of a community health worker-led education intervention on knowledge, perception, and PC screening. Methods This was a quasiexperimental study among Kenyan men aged 40–69 years. The intervention site was Gatundu North subcounty and the control site was Kiambu subcounty in Kiambu County. Stratified random sampling was applied to select 288 respondents per arm of the study. We used a pretested interviewer-administered questionnaire to collect data at baseline and 6 months postintervention. Pearson's chi-square test was used for data analysis. Results Awareness of prostate cancer significantly increased postintervention (P < 0.05). The proportion of respondents who had good knowledge of prostate cancer increased significantly from 49% to 76.4%(P < 0.05) in the intervention arm. The proportion of respondents with a high perception of self-vulnerability increased significantly from 26% to 42.1% (P < 0.05). The proportion of men who had undergone PC screening significantly increased from 4.5% to 20.4% (P < 0.05) in the intervention arm. In postintervention, there was a statistically significant difference in the proportion of men screened for prostate cancer in the intervention and control arm (P < 0.05). Conclusion Health education by community health workers during household visits increased awareness and knowledge, perception, and uptake of PC screening. Utilization of community health worker delivered education is an effective strategy that requires to be adopted to enhance screening.

Addressing Latinx CANcer Care Equity (ALCANCE) Randomized Controlled Trial: Baseline Findings from a Community Health Worker-Led Intervention

By Gladys M. Rodriguez, Emily Wood & 7 more. In this study, we evaluate the efficacy of a CHW-led intervention among patients with cancer to reduce disparities; in particular the effect on patient knowledge of precision medicine.

The effect of a multilevel community health worker-led intervention on health-related quality of life, patient activation, acute care use, and total costs of care: A randomized controlled trial.

6500 Background: Low-income and minority populations have less activation in their cancer care, lower health-related quality of life, greater acute care use and total costs of care than affluent and white populations. Community-based interventions are needed to improve patient experiences and quality of cancer care equitably among these populations. We used community-based participatory methods to refine a previously tested intervention for use in urban communities. The intervention, LEAPS, uses community health workers trained to activate patients in discussions with their cancer clinicians regarding advance care planning and symptom-burden and to connect patients with community-based resources to overcome social determinants of health. We conducted a randomized controlled trial of LEAPS in collaboration with an employer-union health plan in Atlantic City, NJ and Chicago, IL. Members of the employer-union health plan with newly diagnosed with hematologic and solid tumor cancers were randomized to the 6-month LEAPS intervention. The objective of the study was to determine whether LEAPS improved quality of life (primary). Secondarily, we evaluated the effect of LEAPS on patient activation, acute care use, and total costs of care. Methods: We used generalized linear regression models to evaluate differences in quality of life and patient activation scores between groups from baseline to 4- and 12-months post-enrollment and regression models offset for length of follow-up to compare emergency department use, hospitalizations, and total costs of care. Results: A total of 160 patients were consented and randomized into the study (80 intervention; 80 control). There were no differences in demographic or clinical factors across groups. The majority were non-White (74%), female (53%), mean age 57 years with breast (31%) or lung cancer (21%) and Stage 3 or 4 (63%) disease. At 4- and 12-months follow-up, the intervention group had greater improvements in quality of life overtime as compared to the control group (difference in difference: 11.5 p &lt; 0.001) and greater change in patient activation overtime (difference in difference: 11.9 (p &lt; 0.001)). At 12-months follow-up there were no differences in emergency department use (0.44 (0.71) versus 0.73 (0.22) p = 0.22) however intervention group participants had fewer hospitalizations (1.55 (0.86) vs. 2.29 (1.31), p = 0.002) and lower median total costs of care ($72,585 vs. $153,980, p = 0.04). Conclusions: Integrating community-based interventions into clinical cancer care delivery for low-income and minority populations can significantly improve patient activation, reduce hospitalizations and total costs of care. These interventions may represent a sustainable resource to facilitate equitable, value-based cancer care. Clinical trial information: NCT03699748.

A Community Health Worker-Led Intervention to Improve Blood Pressure Control in an Immigrant Community With Comorbid Diabetes: Data From Two Randomized, Controlled Trials Conducted in 2011-2019.

Evidence-based strategies addressing comorbid hypertension and diabetes are needed among minority communities. We analyzed the outcome of blood pressure (BP) control using pooled data from two community health worker interventions in New York City conducted between 2011 and 2019, focusing on participants with comorbid hypertension and diabetes. The adjusted odds of controlled BP (< 140/90 mmHg) for the treatment group were significant compared with the control group (odds ratio = 1.4; 95% confidence interval = 1.1, 1.8). The interventions demonstrated clinically meaningful reductions in BP among participants with comorbid hypertension and diabetes.

A Community Health Worker–Led Multicomponent Program to Promote Cervical Cancer Screening in South Asian Women: A Cluster RCT

South Asian women in Hong Kong have low cervical cancer screening uptake because of multiple barriers to utilizing health resources. Interventions that effectively modify the cancer screening behaviors of this population are warranted. This study evaluates the effects of a community health worker-led multicomponent intervention on improving cervical cancer screening uptake among South Asian women in Hong Kong. This study was an assessor-blind, cluster RCT that included a waitlist control group. Recruitment of eligible subjects took place in 6 nongovernmental organizations; these organizations were randomized into intervention and control groups with a 1:1 allocation ratio. Participants in the intervention group received a 3-month multicomponent intervention comprising health education, monthly telephone follow-ups, and navigation assistance. Participants' cervical cancer screening utilization and beliefs were assessed at baseline, after intervention, and 3 months after intervention. A longitudinal outcome comparison between the 2 groups was performed with generalized estimating equation analysis. Data were collected between September 2018 and January 2020 and were analyzed in 2019-2020. A total of 387 participants completed the intervention. A significantly higher cervical cancer screening uptake was observed among participants in the intervention group (97.9%, 191 of 195) than among participants in the control group (52.6%, 101 of 192) at 3 months after intervention (p=0.005). Significantly greater decrements in perceived barriers to cervical cancer screening were found in the intervention group after intervention (-0.68, 95% CI= -1.35, -0.01, p=0.047) and 3 months after intervention (-0.86, 95% CI= -1.69, -0.04, p=0.041). A community health worker-led multicomponent intervention is effective in promoting cervical cancer screening uptake and in reducing barriers to cancer screening utilization among South Asian women in Hong Kong. Combining a community health worker-led intervention with multiple intervention components could be an effective strategy for developing interventions to increase cervical cancer screening in underserved populations. This study was registered at the Chinese Clinical Trial Registry (http://www.chictr.org.cn) ChiCTR1800017227 on July 18, 2018.

Community health worker-delivered weight management intervention among public housing residents: A feasibility study.

Community health worker-led interventions may be an optimal approach to promote behavior change among populations with low incomes due to the community health workers’ unique insights into participants’ social and environmental contexts and potential ability to deliver interventions widely. The objective was to determine the feasibility (implementation, acceptability, preliminary efficacy) of a weight management intervention for adults living in public housing developments. In 2016–2018, in Boston Massachusetts, we conducted a 3-month, two-group randomized trial comparing participants who received a tailored feedback report (control group) to participants who received the same report plus behavioral counseling. Community health workers provided up to 12 motivational interviewing-based counseling sessions in English or Spanish for diet and physical activity behaviors using a website designed to guide standardized content delivery. 102 participants enrolled; 8 (7.8%) were lost at 3-month follow up. Mean age was 46.5 (SD = 11.9) years; the majority were women (88%), Hispanic (67%), with ≤ high school degree (62%). For implementation, among intervention group participants (n = 50), 5 completed 0 sessions and 45 completed a mean of 4.6 (SD = 3.1) sessions. For acceptability, most indicated they would be very likely (79%) to participate again. For preliminary efficacy, adjusted linear regression models showed mean changes in weight (-0.94 kg, p = 0.31), moderate-to-vigorous physical activity (+11.7 min/day, p = 0.14), and fruit/vegetable intake (+2.30 servings/day, p < 0.0001) in the intervention vs. control group. Findings indicate a low-income public housing population was reached through a community health worker-led intervention with sufficient implementation and acceptability and promising beneficial changes in weight, nutrition, and physical activity outcomes.

Reduction in Cardiovascular Risk Among Latino Participants in a Community-Based Intervention Linked With Clinical Care

Community Heart Health Actions for Latinos at Risk is a community health worker-led cardiovascular disease risk reduction program targeting low-income urban Latinos. The impact of community programs linked with clinical care has not been well characterized. Community Heart Health Actions for Latinos at Risk provided 12 weeks of lifestyle education. Changes in risk factors were assessed before and after completion. Univariate, bivariate, and multivariate analyses were used to determine factors associated with changes in risk factors. From 2009 to 2013, a total of 1,099 participants were recruited and 768 had risk factors measured at baseline and 12 weeks. All analyses were performed in 2016. In participants with abnormal baseline risk factors, significant (all p<0.001) median reductions in systolic blood pressure (-11 mmHg, n=244); low-density lipoprotein cholesterol (-14 mg/dL, n=201); glucose (-8 mg/dL, n=454); triglycerides (-57 mg/dL, n=242); and Framingham risk score (-2.3%, n=301) were observed. Program completion (eight of 12 classes) was associated with the reduction in low-density lipoprotein cholesterol (p=0.03) and systolic blood pressure (p=0.01). After adjustment, low-density lipoprotein cholesterol reduction was greatest in participants newly prescribed lipid-lowering drugs (-30%, 95% CI= -48, -15). A community health worker-led intervention lowered cardiovascular disease risk among vulnerable Latinos. Integration with primary care services was an essential program component.

Breast and Cervical Cancer Screening Literacy Among Korean American Women: A Community Health Worker-Led Intervention.

To test a community health worker (CHW)-led health literacy intervention on mammogram and Papanicolaou test screening among Korean American women. We conducted a cluster-randomized trial at 23 ethnic churches in the Baltimore, Maryland-Washington, DC, metropolitan area between 2010 and 2014. Trained CHWs enrolled 560 women. The intervention group received an individually tailored cancer-screening brochure followed by CHW-led health literacy training and monthly telephone counseling with navigation assistance. Study outcomes included receipt of an age-appropriate cancer screening test, health literacy, cancer knowledge, and perceptions about cancer screening at 6 months. The odds of having received a mammogram were 18.5 (95% confidence interval [CI] = 9.2, 37.4) times higher in the intervention than in the control group, adjusting for covariates. The odds of receiving a Papanicolaou test were 13.3 (95% CI = 7.9, 22.3) times higher; the odds of receiving both tests were 17.4 (95% CI = 7.5, 40.3) times higher. Intervention effects also included increases in health literacy and positive perceptions about cancer screening. A health literacy-focused CHW intervention successfully promoted cancer-screening behaviors and related cognitive and attitudinal outcomes in Korean American women.

Therapeutic Relationship and Study Adherence in a Community Health Worker-Led Intervention.

Community health workers (CHWs) are increasingly utilized to reach low-resource communities. A critical domain influencing success is the CHWs' ability to create and maintain a therapeutic relationship with the participants they serve. A limited evidence base exists detailing this construct, and evaluating CHW-participant relationships in the context of CHW-led programs. In a longitudinal study design, data on this therapeutic relationship were collected [as captured using The Scale to Assess the Therapeutic Relationship in Community Mental Health Care (STAR)] on 141 participants who had been assigned to a CHW during their perinatal period. Results indicate that therapeutic relationship was associated with the participant's psychosocial health, and independently predicted study adherence in the longitudinal intervention. Changes in therapeutic relationship over the months following birth were strongly associated with changes in anxiety and depression symptoms. A trustful relationship is critical in ensuring CHWs can effectively reach the population they serve. The findings offer additional psychometric evidence of the uses and benefits of STAR outside of the traditional clinical setting in the context of public health research.

"The Promotora Explained Everything": Participant Experiences During a Household-Level Diabetes Education Program.

The purpose of this study is to describe participant experiences of a household-level, community health worker-led intervention to improve diabetes-related health behaviors and outcomes. The Home Health Parties (HHP) aimed to improve diabetes self-management among Hispanics living in a rural, agricultural area in eastern Washington State. Trained promotores (community health workers) delivered a series of education sessions and distributed incentives to support diabetes-related behavior change. Open-ended, semi-structured questionnaires were administered to a random sample of 40 HHP participants. Qualitative methods were used to code and analyze the interview transcripts. Four primary themes emerged from interviews: (1) participants' desire for improving knowledge about diabetes; (2) experiences of building skills for diabetes management; (3) developing social support; and (4) embracing household-level change. This study shows that involving family members and increasing social support are effective strategies for improving health behaviors and chronic health outcomes among vulnerable Hispanics living with diabetes. Our findings demonstrate several important considerations regarding the design of diabetes management interventions for rural Hispanic populations including the following: (1) promotores are critical as they provide social support and encourage behavior change by building relationships based on trust and cultural understanding; (2) well-designed tools that provide step-by-step examples of healthy behaviors, such as cookbooks, and tools that aid participants to monitor behavior change, such as pedometers and glucose monitors, serve to build skills and improve confidence to achieve goals; and (3) targeting households is a promising strategy for individual and family lifestyle changes that benefit the entire family unit.
