165 Predicting Success: A Mixed Model of KL2 Trainee Profiles and Outcomes
Authors: Eggleston Alyson , Petrie Jessica
Published: April 2024

OBJECTIVES/GOALS: Penn State CTSI supports KL2 career development awards for faculty seeking to become leaders in clinical and translational research. CTSAs can benefit from a better understanding of KL2 applicant profiles and trainee outcomes. Predictive modeling of KL2 records provides insights into institutional processes and continuous improvement goals. METHODS/STUDY POPULATION: Collecting KL2 application records at Penn State CTSI from 2017 to 2023, comprising both accepted and not accepted candidate profiles, this study used a generalized logistic mixed model with binomial distribution to understand the factors predictive of KL2 trainee acceptance, (n=47). The following factors were modeled as potentially predictive of scholars’ acceptance: Institution-specific Processes—Campus; Terminal Degree Type; College of Residency, Applicant Demographics and Portfolio—Minoritized or Protected Groups; Mean Application Score; Rurality Focus; Gender, and Outcomes—Post-Program h-index. RESULTS/ANTICIPATED RESULTS: Only Campus and Degree were significant factors predictive of trainee acceptance (r<.0001), with a particular campus and the MD degree-designation both exerting selectional pressures on acceptance rates. Applicant demographics were not significant historical factors in selection despite the most recent trainee cohort comprised of all women. Similarly, while our CTSA focuses on rural inequality and accessibility, a research proposal focused on rurality was not a significant factor for acceptance. Notably, NIH-scaled application scores and post-program h-indices were not significant for accepted and non-accepted applicants. DISCUSSION/SIGNIFICANCE: The absence of applicant-focused selectional pressure is striking—Penn State CTSI does not significantly select for gender, URM, or URP status. Administration is now empowered to intentionally engage, recruit, and retain from our other affiliated campuses and colleges.
172 Roles and Expectations for Evaluators within a Learning Health System
Authors: Perry Anna , Easterling Doug
Published: April 2024

OBJECTIVES/GOALS: Our objective is to explore the evolving role of evaluators within Learning Health Systems (LHSs) and the implications for evaluation approaches in these dynamic healthcare environments. We aim to disseminate lessons learned to help inform best practices for other CTSA hubs operating under a LHS model. METHODS/STUDY POPULATION: Our investigation builds upon our prior qualitative analysis of the LHS literature and contextualization of unique challenges, and potential remedies, of a LHS in Academic Health Centers. As evaluators, we are particularly interested in understanding how evaluation work is conducted in LHSs and exploring ways to optimize the role of evaluators and their skillset in this context. For this investigation, we examined the competencies necessary for evaluators working in LHS and the specialized evaluation approaches needed to fulfill these requirements. Our approach drew from multi-faceted data and experience. We leveraged insights from our literature review, direct experience within WFUSOM CTSI, and discussions with other evaluators. This combination of data sources provided the foundation for our analysis. RESULTS/ANTICIPATED RESULTS: We expect that as more health systems move toward the LHS model, they will have an increased need for various forms of evaluation, requiring resources well beyond what they are currently dedicating to evaluation. Expectations for evaluators will be enhanced in the following distinct, yet complementary, categories: generating new knowledge and translating research knowledge into practice. Anticipated results include identifying essential competencies for evaluators in LHS, such as data proficiency, clinical understanding, and adaptive skills. We also expect to uncover various evaluation approaches specific to LHS, including quality improvement studies, pragmatic trials, and stakeholder-engaged research. DISCUSSION/SIGNIFICANCE: Understanding the evolving role of evaluators and specialized evaluation approaches in LHS is crucial. It enhances the ability to generate localized evidence, customize interventions, and improve patient care. This knowledge empowers healthcare systems to adapt, innovate and deliver high-quality care for a higher impact on patient outcomes.

Authors: NoboaU Carlamarie , Picó Mariela Lugo , Morales Luisa , Cabrera Vicmag
Published: April 2024

OBJECTIVES/GOALS: Policy makers are interested in understanding scientific collaborations that translate knowledge into population health. The objective of this study is to compare the translational research collaboration of the Hispanic Alliance of Clinical and Translational Research in 2020 and 2023 by using Social Network Analysis (SNA). METHODS/STUDY POPULATION: We conducted a systematic document review of all the Hispanic Alliance Calls for Pilot Projects from 2020 to 2023 including key attributes of the investigators and collaborators such as academic institution, highest degree, and collaborator type. Scientific collaboration was defined as two or more researchers working together in grant proposal for a pilot project application. Study data was recorded and tracked using an Excel spreadsheet. R Statistical software was used to analyze and map the networks resulting from collaboration interactions comparing the 2020 Call and 2023 Call. Network statistics were performed including nodes, isolates, edges, components, density, diameter, average degree, and the size of the main component. RESULTS/ANTICIPATED RESULTS: A total of 134 investigators comprised the overall network. The network are predominantly clinician (49.3%) and basic researchers (25.4%). Preliminary results shows that diversity of disciplines and affiliations in the collaborative relationships increased across time. Findings demonstrated that the number of nodes/actors increased from 16 to 65 comparing 2020 to 2023 and the edges/relationships from 12 to 53. The number of translational research cluster increased from 4 to 13 comparing 2020 to 2023. More extensive collaborative cluster occurred across time with over 15 researchers collaborating. A mentor was the key player connecting these research clusters. DISCUSSION/SIGNIFICANCE: This study provides critical data to mapping the IDeA CTR translational research collaboration patterns. Research collaboration increased across time. This innovative approach serves to foster data-driven decision-making to enhance collaboration, diversity, and program outcomes. It offers valuable insights for policy and practice.
189 Designing a parent-adolescent-provider intervention to support adolescent girls' use of dual prevention strategies: Results from the Teen and Parent Survey
Authors: Narasimhan Subasri , Thornburg Sarah , Sales Jessica M.
Published: April 2024

OBJECTIVES/GOALS: This study examines health provider andcaregiver influences on adolescent dual prevention strategies, or the use of condoms and another form of contraception, to informa clinically focused triadic intervention, involving caregivers, adolescents aged 15-17, and health providers. METHODS/STUDY POPULATION: Data for the 2021 Teen and Parent Surveywere two online, cross-sectional surveys, a national sample of adolescents aged 15-19, and a survey of caregivers of 15–17-year-old adolescents. Data were matched to create a dyadic dataset (n=273). Drawing from the Actor-Partner-Dependance Model we will conduct a secondary retrospective analysis, specifically cross-sectional univariate, bivariate, and multivariate logistic regression analyses on sets of influences around contraception and sexual health: communication with parents and health providers, information delivery of sexual health, condom attitudes and self-efficacy around preventative behaviors. RESULTS/ANTICIPATED RESULTS: In preliminary unadjusted analyses, 91% of the sample were cis-gender females (n=249), of which 32% (n=87) had sexual contact with someone who could get them pregnant. In the past, 35% (n=86) discussed birth control pills and 9% (n=24) discussed long-acting contraception with a health provider. In the last health visit, 29% (n=72) discussed STI prevention. Caregivers discussed sexual decision-making (49%, n=144), how to prevent pregnancy (62%, n=169), and how to prevent STIs (55%, 151) at least once in the past year. At last sex (n=49) most used condoms (47%, n=23), followed by birth control pills (33%, n=16), and withdrawal (14%, n=7). Additional predictors and adjusted analyses will be further examined. DISCUSSION/SIGNIFICANCE: Dual prevention strategies can be influenced by caregivers and health providers, but they are contingent on communication. Triadic interventions may consider involving both caregiver and health provider communication around sexual health prevention.

Authors: Orellano-Colon Elsa M. , Bonilla-Díaz Wency , Revilla-Orellano Radamés , Mejías-Castro Jesús , Torres-Irizarry Josí , Figueroa-Alvira Nixmarie , Fernández-Torres Angelis M , Ortiz-Vélez Bernice , Torres-Ferrer Gabriela A. , Rivera-Rivera Nina L.
Published: April 2024

OBJECTIVES/GOALS: The use of assistive technology (AT) devices is known to improve older adults’ independence in daily activities. However, little is known about the impact of using an AT web app in older Latinos’ life. This study aims to evaluate the value and usefulness of the My Assistive Technology Guide web app among older Latinos with physical function disabilities. METHODS/STUDY POPULATION: We employed a convergent parallel mixed-method design with 12 community-living older Latinos from Puerto Rico. Researchers provided training in the use of My Assistive Technology Guide, a Spanish evidence-based web app with detailed information on 97 AT devices and videos of older people using them. Participants were encouraged to use it for 30 days. Afterward, we collected quantitative data using the subjective quality domain of the User Mobile Application Rating Scale (uMARS), followed by qualitative data through individual interviews. Quantitative data were analyzed with descriptive statistics and qualitative data with thematic content analysis. RESULTS/ANTICIPATED RESULTS: My Assistive Technology Guide web app received high ratings in the uMARS subjective quality domain (mean 4.5 [SD 0.5] out of 5), indicating that participants highly valued the usefulness of the web app. Qualitative data fell into four main categories: functional health, meaningful participation, autonomy, and personal growth. DISCUSSION/SIGNIFICANCE: The findings suggest that the AT knowledge provided by the My Assistive Technology Guide web app has the potential to enhance the quality of life of older Latinos in the face of the challenges posed by physical function disabilities as people age.

Authors: Williams Sydni , Ravi Meghna , Stanhope Kait , Rocha Mariana , Britt Abby , Chandrasekaran Suchitra , Smith Alicia K , Carter Sierra , Michopoulos Vasiliki
Published: April 2024

OBJECTIVES/GOALS: Low birth weight and preterm birth are significant contributors to infant mortality in the United States that disproportionally impact Black pregnant persons and their offspring. Although these outcomes are linked to chronic stress, the contribution of race-related stress remains largely understudied. METHODS/STUDY POPULATION: We investigated the effect of race-related stress on weight and gestational age at birth in a prospective cohort of 115 pregnant Black persons recruited at Grady Memorial Hospital in Atlanta, Georgia. The Index of Race-Related Stress Brief (IRRS-Brief), Perceived Stress Scale (PSS), and Stressful Events Questionnaire (SEQ) were collected at study enrollment during pregnancy. Neonatal birth weights and gestational age were collected via standardized medical record abstraction. We conducted linear regressions to determine whether greater race-related stress was associated with lower weight and gestational age at birth, while controlling for sources of prenatal stress. RESULTS/ANTICIPATED RESULTS: Global racism (total IRRS score) was significantly associated with birth weight when controlling for prenatal perceived stress and stressful life events within the last six months since study enrollment (beta=−16.7, p=.035). Neonatal gestational age was associated with both global racism (beta=-0.03, p=.028) and individual racism (IRRS’Individual’ subscale score) (beta=-0.09, p=.032) when controlling for prenatal perceived stress and stressful life events within the last six months since study enrollment. These results suggest that greater race-related stress contributes to lower weight and gestational age at birth in pregnant Black persons. DISCUSSION/SIGNIFICANCE: Future studies are necessary to determine the mechanisms by which race-related stress contributes to these adverse birth outcomes and to inform the development risk-assessment tools and interventions to mitigate the threat of race-related stress on adverse birth outcomes in high-risk populations.
198 Community & Recruitment Programs at OHSU: Leveraging a team science approach to ensure representative study populations through community engagement and recruitment
Authors: Campbell Laura , Zauflik Meredith , Davis Melinda
Published: April 2024

OBJECTIVES/GOALS: Investigators are looking to integrate DE&I into trials, increasing study population diversity. In response, the Community and Recruitment programs of the Oregon Clinical and Translational Research Institute (OCTRI), built a collaborative, community-focused system for investigators interested in community engagement and recruitment. METHODS/STUDY POPULATION: Historically, the OCTRI Community and Recruitment programs operated independently. To build a community-focused support system for investigators, we began with the programs learning about each other’s goals, values, and operations over a six-month period. Over the next two years, we then began integrating into each other’s team meetings and processes. Each team has their own process for providing services to investigators, consisting of intake and consultations. To these, we added tags for the other’s program topics. This allowed efficient identification of opportunities for referrals and joint consultations. Program leads meet regularly to discuss referrals and partnerships allowing for more effective and consistent collaboration. RESULTS/ANTICIPATED RESULTS: Over the last two years, OCTRI Community and Recruitment built a collaborative process that allows investigators to work with both programs, receiving comprehensive, supportive assistance and education on how to design their study, engage with community, and recruit participants in a community-based setting. During this time, the programs have: provided consultations that discussed the other’s program (N=21); made direct referrals to the other program (N=4); and, provided joint consultations (N=2). Studies that are investigator-initiated, in planning phase, and population focused were found to benefit most from the collaborative efforts. Additionally, we have improved the collaborative process during this time, resulting in more streamlined, efficient support services for investigators. DISCUSSION/SIGNIFICANCE: Diverse study populations and DE&I are essential to research. This collaborative, community-engaged recruitment approach by our programs allows investigators to leverage both programs’ resources and expertise. We continue to identify best practices and study types that benefit from this collaborative approach to improve our services.
201 Challenges Encountered and Lessons Learned from Developing and Implementing the Michigan Research Engaging the Academy and Community in Health (M-REACH) Platform
Authors: Vereen Donald , McKay Athena , Veinot Tiffany , Piechowski Patricia , Allen Polly Gipson , Woolford Susan J. , Bailey Sarah
Published: April 2024

OBJECTIVES/GOALS: Communities of color often report that their concerns are ignored and desire a means to facilitate effective community-academic engagement, especially during a crisis. The objective is to share lessons learned and challenges faced in the development of an online portal designed to meet this need. METHODS/STUDY POPULATION: The Michigan Institute for Clinical & Health Research (MICHR) worked with community and academics to develop an online tool, the Michigan Research Engaging the Academy and Community in Health (M-REACH) platform. The community-engaged research (CEnR) project involved conducting qualitative interviews exploring connectivity to community and academic organizations and pilot testing of the novel platform. Following development, efforts were made to implement the statewide use of M-REACH. We will report on the challenges encountered and lessons learned from development and optimization of the platform. RESULTS/ANTICIPATED RESULTS: Authors will review the timeline of the launch of M-REACH. Steps to promote engagement of the locally developed platform to statewide utilization will be shared. Challenges encountered with scaling, matching the needs of differing communities both rural and urban, and navigating connections between remote geographies will be presented. Lessons learned and potential solutions will be discussed. DISCUSSION/SIGNIFICANCE: M-REACH can connect partners by increasing understanding of the CEnR process, enhancing alignment, and building a foundation for well-functioning research partnerships. Further work is required to address the challenges encountered in development and implementation.
216 Exploring the development of recovery community organizations in non-metropolitan settings: A community-engaged multiple-methods approach
Authors: Barnes Priscilla A. , Ables Erin , Pittman Caleb , Gaston Mylan , Simpkins Chelsea , Bradley Shaina , Shaw Carrie
Published: April 2024

OBJECTIVES/GOALS: Rural recovery community organizations (RCOs) are key to fostering people’s resilience in the face of the nation’s substance use crisis. However, their development is often a black box. METHODS/STUDY POPULATION: A community-engaged multiple-methods approach was conducted to elucidate stakeholders' perspectives about the creation of two RCOs through a consortium intended to build peer recovery support services in a rural Southern Indiana designated health professional shortage area. Document review (e.g., meeting minutes, event photography, and administrative reports) were extracted to map activities, products, and milestones of the development of the RCOs. Consortium members, RCO leadership and staff, and community members identified by consortium or RCO leadership/staff participated in one-on-one interviews or community roundtable sessions were held to reflect on the evolving development of the RCOs. Procedures were approved by the Institutional Review Board of Indiana University. RESULTS/ANTICIPATED RESULTS: This designated health professional shortage area is unique as it is the nonmetropolitan county with two accredited RCOs. Each RCOs has its own distinct brand. One RCO primarily provide support services to prepare justice-involved individuals who are re-entering the community from jail or probation. The second RCO operates a recovery café – a drug free space that offers accountability groups (recovery circles), volunteer opportunities, and multiple pathway (e.g., 12-steps, referral to medication assisted treatment) meetings. Services are facilitated through peer recovery coaches. Services are provided by certified peer recovery coaches (individuals who has lived experience with addiction and recovery) who offers informational, socio-emotional, and instrumental/basic needs support. DISCUSSION/SIGNIFICANCE: This collaborative rural-based model features recovery community organizations as emerging lead agencies in providing informational, socio-emotional, and basic needs for individuals living in long-term recovery as well as individuals using substances and is not yet in recovery services or acknowledging an addiction is present.
218 Social-ecological approach To Outline Risks to Medication adherence during Disasters (STORM MEDs): Preliminary Results
Authors: Romaine Claire , Peacock Erin , Perry Laura , Murphy Stephen , Krousel-Wood Marie
Published: April 2024

OBJECTIVES/GOALS: Limited access to medication and poor medication adherence exacerbate chronic diseases following disasters. Experts recommend individuals in disaster-prone areas be prepared to manage their chronic diseases in the event of resource disruption. This study’s goal is to identify factors underlying personal medical preparedness. METHODS/STUDY POPULATION: A cross-sectional survey of 120 insured adults age ≥50 in Southeast Louisiana with hypertension and ≥1 daily medication during the 2023 Atlantic Hurricane Season is underway. The survey includes the Household Emergency Preparedness Index Access and Functional Needs Section (HEPI AFN), a validated measure of medical preparedness that accounts for special circumstances including refrigerated medication and electricity-dependent medical equipment. The mean score of the 9-item tool ranges from 0 to 1, with higher scores indicating more preparedness. The survey also includes 3 open-ended questions where participants can explain difficulties with medication adherence during hurricanes in their own voice. Data collection is ongoing. This interim analysis provides descriptive statistics. RESULTS/ANTICIPATED RESULTS: An interim analysis of the first 50 respondents included 46% women, 52% Black, mean age 61.2 (SD=7.3) years, and mean 52.5 (SD=16.2) years living in a hurricane-impacted area. Participants had a median of 1 comorbid condition; 72% reported taking >5 daily medications. Most respondents (94%) stated their household was at least “somewhat prepared” to handle a disaster and reported medical preparedness on an average of 82% of HEPI-AFN items (mean score = 0.82, SD=0.18); 90% reported that they had never had a healthcare worker talk to them about personal medical preparedness. On open response questions, participants cited insurance restrictions as the primary barrier to having extra medication on hand. In the final sample, regression models will be used to examine factors associated with increased preparedness. DISCUSSION/SIGNIFICANCE: While most participants in this insured, disaster-experienced preliminary sample are medically prepared, few have discussed preparedness with a healthcare provider. Identifying socio-demographic factors associated with preparedness will help to strengthen mitigation strategies addressing widening of health disparities during disasters.

Authors: Frank Simone , Datta Nisha , Bilheimer Alicia , Jean-Baptiste Milenka , Tunstall Christopher , Wynn Mysha , May Eva A. , Anderson Mary , Carlisle Veronica , Potter Jennifer
Published: April 2024

OBJECTIVES/GOALS: Community-based participatory research is a “gold standard” methodology, yet many researchers lack the experience or resources to implement this approach. To make engagement more accessible, we developed and implemented a 3-part training series highlighting engagement as a spectrum with many options to meaningfully engage partners. METHODS/STUDY POPULATION: Staff at UNC-Chapel Hill’s CTSA and Cancer Center collaborated with patient and community partners to co-develop training content, structure, and delivery. Sessions were free and open to the public and covered key components of research engagement and its benefits, debunked common myths and misconceptions about engagement, outlined specific methods along the spectrum of engagement (from low to high touch), and described nuances of building and maintaining partnerships. Partners determined how to best incorporate their perspectives, developed content (including videos, audio clips, and quotes), and co-presented with UNC staff. Evaluations were collected after each session and feedback was incorporated into future iterations. RESULTS/ANTICIPATED RESULTS: 194 individuals from over 20 institutions have participated in the training. Of all survey respondents to date (n=74), 93% were very or extremely satisfied, 77% felt the training was very or extremely relevant to their work, and 76% were very or extremely likely to use information learned in the next year. Most helpful parts of the training were differentiating research engagement from participation; explaining engagement as a spectrum with varied methodologies; providing tools and resources to implement different approaches; and hearing directly from community co-presenters about their experiences engaging in research. Based on feedback, we created a workshop for researchers to develop engagement plans and an additional training for partners to build capacity and knowledge about engaging in research. DISCUSSION/SIGNIFICANCE: Engaging partners who are impacted by research can be instrumental to the success of a study. This training can help researchers identify engagement approaches that align with their goals, experience, and resources, as well as the interests and capacity of potential partners, and can serve as a model for those interested in training co-development.
224 Caregiver Perspectives on Telehealth Assessment and Other Supports for Infants with Early Developmental Concerns
Authors: Talbott Meagan , Schmidt Daltrey , Dufek Sarah
Published: April 2024

OBJECTIVES/GOALS: Caregivers often identify signs of autism in infancy but face multiple barriers when seeking specialized evaluations and subsequent services. This study sought to understand the experiences of families with early developmental concerns to identify acceptable and feasible strategies to support them during this period of uncertainty. METHODS/STUDY POPULATION: We interviewed 15 families participating in a larger longitudinal project developing telehealth assessments for infants with early developmental concerns. Interviews were conducted virtually following the final toddler-age assessment, and focused on caregivers’ experiences navigating early concerns, appropriateness of existing supports, and suggestions for future directions. Interviews were transcribed and coded across multiple passes, focusing on both phenomenological experience and frequency of specific supports mentioned. RESULTS/ANTICIPATED RESULTS: Core themes expressed across multiple included: (1) Uncertainty; (2) Navigating Supports; (3) Community and Connection; and (4) Information is Power. Caregivers also provided specific suggestions for addressing these areas. These included suggestions for parent coaching topics, modalities for sharing information with parents (e.g., group meetings, online modules), and research practices. DISCUSSION/SIGNIFICANCE: There have been recent efforts to develop pre-diagnostic interventions for infants, but few studies have investigated the needs and priorities of families during this period. Our approach can help bridge the gap between research and practice by identifying family priorities to target when developing interventions.
236 Association Between Gait Limitation and Alzheimer’s Disease: Comparison among Elderly in Puerto Rico and Mainland U.S.
Authors: Acevedo-Nieto Joel , Martínez Karen , Amaya Claudia , Wojna Valerie
Published: April 2024

OBJECTIVES/GOALS: In 2022, 116,000 Puerto Ricans were estimated to be affected by Alzheimer’s disease (AD). Gait limitation (GL) has been associated with different stages of AD. We study the GL-AD association in two elderly populations: Hispanics residing in PR and Americans in the mainland U.S., and identify the effects, and social determinants of health. METHODS/STUDY POPULATION: We propose a cross-sectional study involving data analysis from elderly (>65 years) Hispanics in PR and Americans in the U.S. Data will come from the National Alzheimer Coordinating Center (NACC) and a cohort of AD in PR. Our analysis will consider gait parameters, cognitive performance assessments, and AD stage (mild, moderate, and severe) as determined by the Alzheimer’s Association. We will examine social determinants of health and their association with GL and cognitive performance by AD. RESULTS/ANTICIPATED RESULTS: Our analysis will evaluate data about GL and AD stages to 1) investigate the association between GL and the distinct stages of AD and 2) evaluate the effects of social determinants of health in the association between GL and AD. We seek to profoundly understand how these factors interact within elderly populations. This exploration encompasses a diverse demographic, including elderly individuals in the U.S. and PR. We seek to identify disparities in social determinants among elderly individuals experiencing GL and AD by comparing PR and US populations. Through this association analysis, our study aspires to offer insight into the connections between GL and AD while considering the effects of social determinants of health in diverse populations. DISCUSSION/SIGNIFICANCE: The prevalence of AD is higher among Hispanic populations (e.g., Puerto Ricans) in the USA when compared to other ethnic groups. Experiencing GL may affect their daily lives, leading to exacerbating AD stages. The findings from this study will contribute to possible interventions to improve their GL and AD progression.
239 Promoting Health Equity in South Los Angeles: A Place-Based Initiative in the Nickerson Gardens Housing Development
Authors: Wolfe Nicole , Nance Tyrone , Rubio-Diaz Mayra , Seals Natayla , Karpilow Esther , Garcia Alma , Calderon Sara , Kipke Michele D.
Published: April 2024

OBJECTIVES/GOALS: Partnering with the Housing Authority of Los Angeles, we launched a place-based initiative in the Nickerson Gardens housing development in South Los Angeles, where we apply our community engagement approach of listening and learning, and trust and relationship building, to deliver public health interventions in a discrete community. METHODS/STUDY POPULATION: Nickerson Gardens is the largest housing development in Los Angeles, with 1,066 units and over 3,000 residents. 58% and 40% of the residents are Hispanic and Black/African American respectively with an average yearly income of less than $30,000. To build trust and establish relationships, our team began attending community events, holding weekly educational workshops, and participating in the summer program for youth. We also held listening sessions in English and Spanish that asked aboutthe overall health of the Nickerson Gardens community, environment and public space, access and barriers to care, needed healthcare services, and the lived experience within Nickerson Gardens. RESULTS/ANTICIPATED RESULTS: To date, we have held eight 90-minute listening sessions in English and Spanish with 59 participants. The sessions provided insight into theneeded health and educational resources and services, the organizational structure of the housing development and how that impacts access to information and services, as well as the nuanced and area-specific transportation issues and the connection to safety concerns. These findings will inform the next phase of this initiative which includes convening a Coordinating Council composed of service providers and Nickerson Gardens residents. This council will oversee the coordination and implementation of needed services, help maintain accountability of the providers, and offer residents the opportunity to take ownership of the process. DISCUSSION/SIGNIFICANCE: Academic-community partnerships are an effective strategy to deliver public health interventions and promote health equity in under-resourced communities. We tested and measured impact in a distinct community to reinforce a widely-applicable place-based model.
245 Drawing on Arts-Based Methodologies to Elicit Transgender and Gender Diverse (TGD) Children’s Experiences in Health Care
Authors: Lenne Eline
Published: April 2024

OBJECTIVES/GOALS: Understand how prepubescent TGD children experience pediatric care with a dual purpose of informing clinical practice and presenting alternative methods for research with children. Centering their perspectives is critical to improving care for this age group, ultimately improving TGD health. METHODS/STUDY POPULATION: A participatory arts-based study involving drawing, photo elicitation, and narrative interviews with prepubescent TGD children (n=15) in the Pacific Northwest. Participants will make photos and draw a picture of their most recent pediatric visit. Participants guide the analysis and interpretation of their artwork, informing subsequent interviews. Interviews are coded and interpreted using inductive thematic analysis at the semantic level, and verified by participants and near-peer community partners. The combination of multiple data sources that represent both stimuli and verifiers of perceptions provide methodological triangulation. RESULTS/ANTICIPATED RESULTS: Early pilot data with community partners suggest that TGD children do not feel sufficiently supported in pediatric settings, which impacts their sense of safety and agency in the clinical context. Findings will inform changes to clinical practice to improve gender affirmation for prepubescent children, positively impact child-caregiver relationships, and ultimately improve health care and wellbeing for TGD people. Observations related to the implementation of novel methodologies will inform future research practices intended to include younger children as active agents in the knowledge production process. DISCUSSION/SIGNIFICANCE: There are missed opportunities to positively impact children’s health and caregiver-child relationships when gender affirming care is overlooked in the pediatric context. This study provides first-hand multi-media perspectives to inform improvements in prepubescent gender affirming pediatric care.

Authors: Linscott Martha , Biernacki Diane , Dunn E. Mendy
Published: April 2024

OBJECTIVES/GOALS: Disparities persist among minority and marginalized populations in immunizations and research. The Clinical Research Vehicle Team aimed to bring research to our community’s doorstep, building generalizability of research outcomes. Our mission adapted due to the pandemic to include increasing COVID-19 vaccinations and health education. METHODS/STUDY POPULATION: Community Engagement Events are planned when event organizers submit a request, then the proposal is discussed by the Clinical Research Vehicle (CRV) Team and UF HealthStreet. We go to underserved communities throughout Florida, food distributions, churches, community centers, rural areas, etc. At these events we offer services at no cost, including: COVID-19 and flu vaccines, as well as health screenings. We provide health education to individuals and refer them to UF HealthStreet for community resources, as appropriate. Research events are planned when researchers submit a request for the CRV, then the request is discussed by the CRV Team. The studies covered topics from COVID-19 research to the development of a diverse health database. Our fleet consists of two Community Health Vehicles and the CRV. RESULTS/ANTICIPATED RESULTS: As Community Engagement Events are ongoing, the presented numbers are reflective of the data available at the time of submission. Our impact includes administering 1,606+ COVID vaccines, conducting 1,081+ health screenings, collecting data from 944 screenings, providing 265 Flu vaccines, supporting 267+ community health events, and serving 25+ communities. The Clinical Research Vehicle facilitated 6 IRB-approved studies, administration of monoclonal antibody infusions, extended the capabilities of the Clinical Research Center, and enabled clinical trials aimed for novel treatments for COVID-19 positive participants. DISCUSSION/SIGNIFICANCE: Championing this initiative has shown an impact on vaccination rates and health education in communities. Experience and knowledge gained by our team throughout the pandemic while engaging with community members provided a platform from which to build generalizability of research outcomes and support translational science.
265 Association of premature birth with neurodevelopment delays in a cohort of Hispanic children exposed to the Neonatal Intensive Care Unit (NICU)
Authors: Colón Díaz Keimarisse , González Polaris , Fragoso Lourdes García , Ardila Amaya , Martínez Karen
Published: April 2024

OBJECTIVES/GOALS: We aim to identify neurodevelopment delays among children who were born prematurely. We will also calculate the sensitivity and specificity of the assessment tools used to measure the neurodevelopmental profile in early childhood of children exposed to the Neonatal Intensive Care Unit (NICU). METHODS/STUDY POPULATION: This cross-sectional study will include 100 premature children who were born between 32 to 37 weeks of gestational age and admitted to NICU at the University Pediatric Hospital in Puerto Rico. Their neurodevelopment will be measured with the Bayley III. Statistical analysis will be performed using IBM SPSS Statistics 25.0. Descriptive statistics will be used, normality distributions among all continuous variables, frequency distribution for categorical variables and logistic regressions to test association of GA and neurodevelopment delay. We will use the raw item scores for each domain of the Bayley III assessments to measure internal consistency using Cronbach’s alpha and factor analysis. RESULTS/ANTICIPATED RESULTS: We anticipate identifying the ND among children born prematurely between 32 to 37 weeks of gestational age and who were admitted to NICU at the University Pediatric Hospital in Puerto Rico. We also expect to find if gestational age impacts adversely ND in children who were born between 32 to 37 weeks of gestation. We will be able to assess if lower gestational age will impact global ND in contrast to higher gestational age neurodevelopment delays in one specific area of development. We will also be able to assess the sensitivity and specificity of the Bayley- III. DISCUSSION/SIGNIFICANCE: Premature is a major global health problem with a 12.0% prevalence. We want to promote early identification of ND in a diverse Hispanic Puerto Rican population so we can guide public health decisions and lead research initiatives to improve outcomes in the future or facing prematurity.
267 Bridging Health Equity: A Model for Primary Healthcare in the Hamilton, Ontario’s Keith Neighbourhood
Authors: Kelly-Ruetz Carolyn , Porteous Morgan , Nagaratnam Subiksha
Published: April 2024

OBJECTIVES/GOALS: A primary care clinic is opening in the Eva Rothwell Center (ERC) located in the Keith Neighbourhood of Hamilton, Ontario. This new clinic aims to address rampant health disparities in the community. Effective delivery of health services requires a robust model of care that meets and sustains the specific needs of the community and clinic providers. METHODS/STUDY POPULATION: The primary objective of this study is to describe the current health needs of Keith Neighbourhood residents. The secondary objective is to describe the needs of health providers working within the ERC health clinic. Data collection will involve the collection of primary data (through methods such as surveys and interviews) and secondary data (including historical and current census data). Primary data analysis for primary will use conventional quantitative and qualitative methods. Finally, researchers will use the analyzed data to develop a context-appropriate initial model of care for the ERC health clinic and a subsequent evaluation plan to assess the model’s effectiveness and sustainability. RESULTS/ANTICIPATED RESULTS: All primary and secondary data will be synthesized into a report that will inform the development and implementation of two main deliverables. The first deliverable will be a framework for the clinic’s initial model of care that is context-appropriate to the current needs of the Keith Neighbourhood. The model of care will be culturally sensitive and trauma-informed. The second deliverable will be an evaluation plan for the clinic that can be used to continuously iterate on the initial model, ensuring its sustainability. Furthermore, the project’s process may be extrapolated into a framework that could be used to establish primary care clinics within other priority communities. DISCUSSION/SIGNIFICANCE: The proposed model of care will enable practitioners to deliver relevant and timely health services while being adaptable to the community’s evolving needs. It will help improve the Keith Neighbourhood residents' long-term health and social outcomes. This project will contribute to and inform the development of the field of translational science.

OBJECTIVES/GOALS: The peer-reviewed journal Progress in Community Health Partnerships (PCHP) promotes health research partnerships to improve community health. PCHP’s Writing, Dissemination and Reviewer Learning Community Pilot aims to increase stakeholders writing and reviewing for greater relevance and diversity. METHODS/STUDY POPULATION: Led by PCHP’s Editorial Team, Morehouse SOM, Community-Campus Partnerships for Health (CCPH) and a community-academic Workgroup, the LC will guide stakeholders on scholarly writing and publish collaborative research. It builds on the 2017 Writing/Dissemination Learning Institute held by Morehouse, CCPH, and Community Based Organization Partners with the APHA Public Health Caucus. The LC begins with a Workshop [https://sites.google.com/view/pchp2023/pchpcommunity2023] alongside the 2023 APHA Annual Meeting. Wrap arounds include a PCHP Special Issue (participants work), Webinars, PCHP Reflections/Community Perspectives Article Guidelines [https://www.press.jhu.edu/journals/progress-community-health-partnerships-research-education-and-action], “Beyond the Manuscript [https://open.spotify.com/show/2LiBanXAyHyOqNSeGnBPHs]” Podcast, Toolkit/Resources; and coaching. The evaluation will inform PCHP practices. RESULTS/ANTICIPATED RESULTS: Key outcomes include successful implementation of all LI activities. The cohort (approximately 40 stakeholders representing partnerships) will increase exposure to scholarly writing and peer review, ideally publish 12+ manuscripts (e.g., PCHP special issue), increase diversity in scholarly writing, and strengthen recognition/significance of stakeholder authorship in the research community. The year 1 pilot evaluation (e.g., tracking participant authorship, documenting outcomes/lessons learned) will provide evidence to encourage sustainability, model responsiveness among other peer reviewed journals, inform PCHP, and increase diversity in scholarly writing on health disparities research. DISCUSSION/SIGNIFICANCE: The pilot will build a sustainable model and how PCHPaddresses health disparities to increase diversity, equity, and inclusion. The LC aims to diversify framing community health research, supporting/publishing stakeholders work, and increasing diversity among reviewers, all impacting the field.

OBJECTIVES/GOALS: The objective of this study is to investigate the neurophysiological mechanism of vision therapy in male and female adolescents with persistent post-concussion convergence insufficiency (PPCS-CI). This study may improve diagnostics and inform more effective personalized point of care treatment strategies to remediate symptoms. METHODS/STUDY POPULATION: Participants (ages 11-25) were diagnosed with PPCS by a physician, CI was diagnosed by an optometrist and OBVAT was performed by certified therapists. Patients with PPCS-CI were randomly assigned to a therapy type (immediate therapy or natural recovery). Hemodynamic measures were examined in patients with PPCS-CI at baseline (1-3 months post-concussion), and post OBVAT to evaluate recovery outcomes. Non-invasive techniques were used to measure middle cerebral artery velocity (MCAv), blood pressure, heart rate, and end-tidal CO2 at rest and during objective symmetrical convergence step eye movements. Functional magnetic resonance imaging (fMRI) was acquired during convergence step eye movement experiments contrasted to sustained fixation and resting state data collection. RESULTS/ANTICIPATED RESULTS: To investigate the neural mechanism of OBVAT, eye movements, fMRI and physiological measures were collected in 8 patients with PPCS-CI (4 men and 4 women). Results show an 10% decrease in the MCA during 4-degree symmetrical convergent eye movement responses in males post-OBVAT and a 19% increase in MCA during convergent eye movement responses in females. Furthermore, there was a group level activation of the frontal eye fields, which improves post-OBVAT. The beta weights in the left frontal eye fields show a trending decrease in male patients post-OBVAT and trending increase in females. Males had a decrease in MCAv post OBVAT (baseline 83.6 ± 7.5 cm/sec & 75.7 ± 12.5 cm/sec post-OBVAT), while females show a significant increase post-OBVAT (baseline 53.77 ± 5.2 cm/sec & post-OBVAT 65.13 cm/sec ± 12.5). DISCUSSION/SIGNIFICANCE: This initial pilot demonstrates there may be different underlying pathophysiological outcomes associated with a concussion dependent on sex. This work may have direct implications on treatment strategies for male and female adolescent patients with PPCS-CI.
287 Perceptions of Scientist and Community Members Regarding the Social Responsibility of Translational Science.
Authors: Subrahmanyam Vishnu R
Published: April 2024

OBJECTIVES/GOALS: Translational Science includes the social responsibility to improve health outcomes and reduce disparities. This study aims to determine how scientists and community members perceive the social responsibility of translational science. METHODS/STUDY POPULATION: Methods include a series of 12 one-hour semi-structured focus groups. Six groups were held with a total of 34 scientists and four with approximately 32 community members (community focus groups still ongoing). Sample includes scientists and community members affiliated to one of three research fields: HIV/AIDS, Maternal Health, and Mental Health/Substance Use. Inclusion criteria for scientists were based on their scholarly contributions to a field. Community members included individuals who self-identified as affiliated to any above fields. Using reflexive thematic analysis, we analyzed the transcripts against existing frameworks on social responsibility. RESULTS/ANTICIPATED RESULTS: Literature on social responsibility suggests that translational science should be relevant, usable and sustainable for end-users. Scientists and community members identified the same groups for whom research is relevant. Scientists often conceptualized social responsibility through the sustainability lens, focusing on results that might have long-term societal impacts. Due to this, they saw limitations to social responsibility in academia and funding structures. Community members often conceptualized social responsibility through the usability lens, focusing on the complexity of research use and access. They saw barriers to social responsibility in systemic disparities. DISCUSSION/SIGNIFICANCE: Although participants emphasized different practices in focus groups, participants seemed generally interested in pursuing future discussions to develop best practices and commitments regarding social responsibility. Further discussions will take place in a deliberative dialogue activity in January 2024.
