Racially minoritized groups are more likely to experience COVID-19 vaccine hesitancy and have lower vaccination rates. As part of a multi-phase community-engaged project, we developed a train-the-trainer program in response to a needs assessment. "Community vaccine ambassadors" were trained to address COVID-19 vaccine hesitancy. We evaluated the program's feasibility, acceptability, and impact on participant confidence for COVID-19 vaccination conversations. Of the 33 ambassadors trained, 78.8% completed the initial evaluation; nearly all reported gaining knowledge (96.8%) and reported a high confidence with discussing COVID-19 vaccines (93.5%). At two-week follow-up, all respondents reported having a COVID-19 vaccination conversation with someone in their social network, reaching an estimated 134 people. A program that trains community vaccine ambassadors to deliver accurate information about COVID-19 vaccines may be an effective strategy for addressing vaccine hesitancy in racially minoritized communities.

Objectives: We sought to create a computational pipeline for attaching geomarkers, contextual or geographic measures that influence or predict health, to electronic health records at scale, including developing a tool for matching addresses to parcels to assess the impact of housing characteristics on pediatric health., Materials and Methods: We created a geomarker pipeline to link residential addresses from hospital admissions at Cincinnati Children's Hospital Medical Center (CCHMC) between July 2016 and June 2022 to place-based data. Linkage methods included by date of admission, geocoding to census tract, street range geocoding, and probabilistic address matching. We assessed 4 methods for probabilistic address matching., Results: We characterized 124 244 hospitalizations experienced by 69 842 children admitted to CCHMC. Of the 55 684 hospitalizations with residential addresses in Hamilton County, Ohio, all were matched to 7 temporal geomarkers, 97% were matched to 79 census tract-level geomarkers and 13 point-level geomarkers, and 75% were matched to 16 parcel-level geomarkers. Parcel-level geomarkers were linked using our exact address matching tool developed using the best-performing linkage method., Discussion: Our multimodal geomarker pipeline provides a reproducible framework for attaching place-based data to health data while maintaining data privacy. This framework can be applied to other populations and in other regions. We also created a tool for address matching that democratizes parcel-level data to advance precision population health efforts., Conclusion: We created an open framework for multimodal geomarker assessment by harmonizing and linking a set of over 100 geomarkers to hospitalization data, enabling assessment of links between geomarkers and hospital admissions., (© The Author(s) 2024.

Objective: Worsening rates of infant and maternal mortality in the United States serve as an urgent call for multi-modal intervention. Infant Well Child Visits (WCVs) provide an opportunity for prevention, however not all infants receive the recommended schedule of visits, with infants of low-income and Black families missing a higher portion of WCVs. Due to diverse experiences and needs of under-resourced communities throughout the United States, caregiver voice is essential when designing improvement efforts., Methods: Purposeful sampling and interviewing of 10 caregivers in Cincinnati, OH was performed by community peer researchers. Interview transcripts were evaluated by the research team, with identification of several important themes., Results: Nine out of 10 caregivers self-identified as Black. All young children of the interviewed caregivers had Medicaid as their insurance provider. All interviews highlighted rich perspectives on caregiver hopes for their child, family, and selves. Establishing trust through empathy, shared decision making, and the nurturing of interpersonal patient-practitioner relationships is crucial for fostering a positive healthcare experience. Levels of mistrust was perceptibly high across several interviews, with lack of racial concordance between medical provider and family exacerbating the issue for some caregivers. Caregivers voiced a tendency to rely on family and community members for when to seek out health care for their children, and additionally cited racism and perceptions of being rushed or judged as barriers to seeking further care., Conclusion: This study emphasizes the importance of being community-informed when considering interventions. Prior research on the topic of missed WCV's often focused on material resource availability and limitations. While that was commented on by caregivers in this study as well, equal-if not more-attention was directed toward interpersonal relationship formation, the presence or absence of trust between practitioner and caregiver, and the importance of social-emotional support for caregivers. We highlight several opportunities for systemic improvements as well as future directions for research., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.
