OBJECTIVES/GOALS: Historically, Latino farmworkers have lacked access to healthcare. 1 Telehealth promises to bridge this gap in hardly-reached populations. 2 We evaluated the impacts of ACTIVATE, a community-engaged project co-developed withcommunityp artnersAmplaHealth, and a local grower. METHODS/STUDY POPULATION: Mixed-methods outcome evaluation included attitudes survey, knowledge tests, attendance records, exit interviews, and participant observations. Attitudes survey, based on the Unified Theory of Acceptance and Use of Technology (UTAUT) model 3, measured Latino farmworkers’ telehealth acceptability. Pre/Post knowledge tests measured participant knowledge gained on telehealth and mental health services. Semi-structured exit interviewsidentifiedthe impacts of incentives, Promotora training, and health education curricula on participants and community partners. Structured participant observation as certained the level of participant engagement and Promotora facilitation skills. RESULTS/ANTICIPATED RESULTS: Results [https://drive.google.com/file/d/1jQpQdDM3dIR_PzMc1xXPh45Jvz8uBka6/view] On what aspects of the project worked well: “This project really helped us… to make it a priority, to do [health education] workshops. When I was hired, we went out to a few farms and shared information about our services, but it wasn’t anything hugely structured like what you proposed. We hadn’t done a whole lot of Promotora health education prior to this project.” -Ampla Health Administrator The most significant change observed: “Their attitudes… I feel that the very first session, I saw how they were more laid back, not really answering questions, just listening to us. And then the second one… they were more talkative and the very last one they were more comfortable sharing.” -Promotora DISCUSSION/SIGNIFICANCE: Attendence and participant engagement increased over time. Results from the evaluation point to greater telehealth acceptability among participants, increased health education capacity among Ampla Health, and farm worker cohesiveness at the workplace.

OBJECTIVES/SPECIFIC AIMS: Determine whether children with solid tumors maintain intact protective immunity to live vaccines during cancer therapy and after completing cancer therapy (postTx). METHODS/STUDY POPULATION: We will perform a prospective cohort study of children with solid tumors (Hodgkin lymphoma, brain, Wilms, and germ cell tumors) followed at the Puerto Rico’s University Pediatric Hospital. Protective immunity will be measured with antibody titers against live vaccines (Measles, Mumps, Rubella, and Varicella) at diagnosis, during cancer therapy, upon completion and 3 months postTx. RESULTS/ANTICIPATED RESULTS: We hypothesize that those patients with protective immunity to live vaccines prior to cancer therapy will lose it at the end of therapy. DISCUSSION/SIGNIFICANCE OF IMPACT: Loss of protective immunity to live vaccines has been reported in patients with hematologic malignancies after cancer therapy. This lack of protective immunity, which puts patients at higher risk of acquiring vaccine preventable diseases, has been limited studied in patients with solid tumors. The Center for Diseases Control has been established that it is safe to immunize cancer survivors with live vaccines 3 months post Tx. However, no clear guidelines for revaccination have been provided for this population. Understanding the protective immunity variation against live vaccines in children with solid tumors will allow us to identify the need for revaccination with live vaccines in this vulnerable population.

OBJECTIVES/SPECIFIC AIMS: In an effort the increase awareness and enhance knowledge and skills in relation to communication in science at Mount Sinai, the Communication in Science summer workshop series aimed to provide an accessible, workforce-wide lecture series to promote key concepts and skills related to communicating science. Delivered by faculty and invited speakers, a series of seven workshops delivered over a 4 week period covered topics such as communication in teams, storytelling and TED talk principles, and community engagement. The aim of each session was to offer “top tips” that participants could apply to their practice. Evaluation of the workshop series aimed to determine participant satisfaction and self-perceived changes in knowledge and skills in relation to science communication. METHODS/STUDY POPULATION: A total of 375 participants registered to attend the workshop series from a range of backgrounds including post-docs, faculty, residents, staff and students at Mount Sinai. Attendance at the workshops ranged from a high of 119 and a low of 33 participants, with as many as 41% of attendees joining the session via live-streaming. Participants were emailed an online survey at the end of the workshop series, asking for satisfaction feedback on each individual workshop and an overall impression of the workshop series. Participants were asked to rate the satisfaction criteria related to content, gained knowledge and skills, presentation style and whether they found the session of value for each workshop, using a Likert scale from 1 - 5 (1 = strongly disagree, 5 = strongly agree). Participants were also asked to provide an overall rating for the summer workshop series as a whole. RESULTS/ANTICIPATED RESULTS: A total of 35 participants responded to the survey. Mean responses to the survey questions were:. The content of this session is important to my work = 4.09 (range 3.77 – 4.45). This session increased my knowledge or skills 4.03 (range 3.56- 4.62). The presenters delivered this content clearly = 4.16 (range 3.78 – 4.67). Overall I found this session valuable = 4.13 (3.78 – 4.61) Participants were also asked to provide an overall rating for the summer workshop series as a whole on a scale of 1 to 10 (1 = poor, 10 = excellent). The mean response was 8.36, indicating a high level of satisfaction with the program. Qualitative feedback indicated that the sessions were successful in increasing awareness of this topic. One participant reported that “these sessions inspired me to think differently, and in a way that can potentially allow me to communicate with the non-science community”. DISCUSSION/SIGNIFICANCE OF IMPACT: The high number of registrants for this summer workshop series indicates a perceived need for education and training on Communication in Science at Mount Sinai. Sessions that focused on TED talk principles and storytelling in science were particularly well attended and well-reviewed, suggesting a particular interested in these topics. There was, however, a discrepancy between registration and attendance numbers, which going forward we will seek to better understand. One explanation is that recording and posting the sessions on YouTube allowed participants to review content asynchronously at a time and location convenient to them, which may have deterred people from attending in person. Following the popularity of this program, future plans are underway to provide an ongoing program of learning in relation to Communication in Science.

Objectives/Goals: The Clinical Research Education in Genome Science (CREiGS) program was developed to address the need for faculty and trainees conducting biomedical research to gain foundational training in genome science and accelerate the clinical adoption of genomic medicine. CREiGS, funded by NHGRI, offers comprehensive training in genomic analysis and statistical computing. Methods/Study Population: CREiGS targets a diverse pool of medical/doctoral students, postdocs, and faculty from academic institutions nationwide. The hybrid program included an 11-week online phase and a 3-day in-person phase, focusing on genomic science, statistical analysis and R programming, rigor and reproducibility, and engaging diverse populations in genomics research. Advanced special topics lectures included: decision analysis for genomics research, bioethical engagement of indigenous communities in genomics research, elucidating gene networks for advancing human health, etc. Strategies for recruiting diverse participants and ensuring an inclusive learning environment were informed by the Diversity Recruitment External Advisory Board. Participants’ skills were evaluated via pre- and post-course surveys. Results/Anticipated Results: Of 187 participants over 5 cohorts, 68.4% were female and 47.0% from underrepresented groups. The cohort spanned career stages, with 35.3% students, 34.2% postdocs, and 30.4% faculty, most of whom were at the junior level. Competency evaluations showed improvements in all core competencies of the course: (1) independently carrying out small-scale research improvements, (2) confidence collaborating with statisticians, bioinformaticians, and other genome science experts, (3) applying appropriate statistical methods for the analysis of genetics and genomics data, (4) accurately interpreting findings from genome research studies, (5) critiquing the internal/external validity of genome research studies, and (6) effectively engaging diverse populations and community stakeholders. Discussion/Significance of Impact: CREiGS successfully provided inclusive, high-quality, genomic and statistical training, to diverse scientists enhancing their research capacity and methodologic competency. Findings from longer term evaluations examining the contribution of CREiGS to participants’ genome science-related scholarly productivity are forthcoming.

The coronavirus disease 2019 (COVID-19) pandemic requires urgent implementation of effective community-engaged strategies to enhance education, awareness, and inclusion of underserved communities in prevention, mitigation, and treatment efforts. The Texas Community-Engagement Alliance Consortium was established with support from the United States’ National Institutes of Health (NIH) to conduct community-engaged projects in selected geographic locations with a high proportion of medically underserved minority groups with a disproportionate burden of COVID-19 disease and hospitalizations. The purpose of this paper is to describe the development of the Consortium. The Consortium organized seven projects with focused activities to address COVID-19 clinical and vaccine trials in highly affected counties, as well as critical statewide efforts. Five Texas counties (Bexar, Dallas, Harris, Hidalgo, and Tarrant) were chosen by NIH because of high concentrations of underserved minority communities, existing community infrastructure, ongoing efforts against COVID-19, and disproportionate burden of COVID-19. Policies and practices can contribute to disparities in COVID-19 risk, morbidity, and mortality. Community engagement is an essential element for effective public health strategies in medically underserved minority areas. Working with partners, the Consortium will use community engagement strategies to address COVID-19 disparities.

Objectives/Goals: This study objective is to evaluate the prevalence and risk factors of burnout in practicing radiologists, with a focus on personal as well as systemic factors. It aims to identify and assess the existing strategies to mitigate burnout, enhance radiologist performance, and improve the quality of patient care. Methods/Study Population: The present study is a systematic review that summarizes existing literature on burnout in radiology, examining its prevalence, risk factors, and effect on diagnostic accuracy, decision-making, and job satisfaction. The review will synthesize validated evidence for emotional exhaustion, depersonalization, and professional fulfillment. The review discusses trends and solutions that have emerged from analysis of data within differing countries, subspecialties, and career stages, focusing on elevated risk of burnout in radiologists. It also assesses downstream effects on patient care quality such as missed diagnoses and increased medical errors. The review also discusses potential strategies for mitigating these negative effects on healthcare delivery. Results/Anticipated Results: The anticipated results of this review are expected to reveal significant variability in burnout rates across radiology subspecialties and practice settings, with prevalence ranging from 33% to 88% (Fawzy et al., 2023). Emotional exhaustion and depersonalization emerge as the most reported symptoms as consistently highlighted in previous studies. Major contributors such as workload, administrative burdens, and technological isolation (e.g., remote work and reduced face-to-face interaction) are anticipated. Radiologists in high-demand areas like interventional radiology and those in private practice may show higher burnout levels than those in academic settings. Protective factors, like exercise, supportive environments, and work-life balance, are expected to reduce burnout levels. Discussion/Significance of Impact: This study calls attention to the importance of addressing radiologist burnout as a key institutional priority. Early and effective interventions are essential for improving job satisfaction, reducing medical errors resulting in enhanced patient care. Addressing burnout is crucial for maintaining a sustainable and effective radiology workflow.

OBJECTIVES/GOALS: Our goal is to develop a cost-effective approach for precision medicine treatment by providing computational predictions for new uses of currently available FDA approved, and experimental drugs for NSCLC. METHODS/STUDY POPULATION: Cell Lines: A549 (ATCC- CCL-185) Human epithelial Lung Carcinoma cells, H1792 (ATCC-CRL-5895) Human Lung Carcinoma cells. In Vitro Cytotoxicity Assay: A Vybrant® MTT Cell Proliferation Assay was used. Colony Formation Assay: NCI-H1792, A549 cells were seeded at a density of 500 cells/ dish, then treated with ARS-1620, Osimertinib. The Computational Analysis of Novel Drug Opportunities (CANDO):  Herein, we employed the bioanalytic docking (BANDOCK) protocol within CANDO to calculate the compound-protein interaction scores for a library of 13,218 compounds from DrugBank against a library of 5,317 protein structures from the Protein Data Bank, resulting in a proteomic interaction signature for each compound, and identified Osimertinib as the most likely EGFR/ErbB inhibitor to synergize with ARS-1620. RESULTS/ANTICIPATED RESULTS: ARS-1620 and Osimertinib in combination displays potent anti-tumor activity as evident by a decrease in cell viability with cytotoxicity assays, as well as reduced number of colonies in the colony formation assay for both A549 and H1792 cells. By using CANDO, and cross-referencing the obtained rankings with known experimental information, we have obtained drug predictions within the context of precision medicine. Our preliminary data indicates that EGFR inhibitor Osimertinib may be most structurally similar to KRAS G12C inhibitors overall, compared to other ErbB/ EGFR inhibitors. Validations with human cancer cell lines A549 and H1792 have confirmed that Osimertinib in combination with KRAS G12C inhibitor ARS-1620 may exhibit a synergistic effect in decreasing cellular proliferation and colony formation. DISCUSSION/SIGNIFICANCE: This suggests that this innovative drug combination therapy may help improve treatment outcomes for KRAS G12C(H1792) and KRASG12S(A549) mutant cancers. Cell migration and cell invasion studies in response to treatment with Osimertinib and ARS-1620 are currently ongoing.

OBJECTIVES/SPECIFIC AIMS: Stakeholder engagement has been proposed to help realign clinical and translational research with the needs of clinicians, patients, and policymakers. Increasingly, funders and researchers seek to partner with stakeholders to inform study design, execution and dissemination of results. Kids and families Impacting Disease through Science (KIDS) is a program of the American Academy of Pediatrics that seeks to engage youth in clinical research. United States KIDS programs participate in International Children’s Advisory Network activities. The Chicago KIDS Advisory Board program at Walter Payton College Preparatory School, a Chicago Public School, was initiated in 2015 to foster and develop interest in careers in science, research and healthcare and provide youth perspectives to academic and industry researchers on the design and development of pediatric research studies. This project engaged youth advisors in creation and evaluation of a video explaining clinical research and informed consent for Ann & Robert H. Lurie Children’s Hospital, a clinical partner of the Northwestern University Clinical and Translational Sciences Institute. METHODS/STUDY POPULATION: The Payton program advisory board sessions are 1.5hr interactive seminars held on 1–2 school days each month. During the 2016–2017 school year, students participated in 3 stakeholder sessions, led by Lurie Children’s hospital researchers, to advise development of a script, storyboards, and ultimately an animated video that informs children and families about participation in clinical research to aid in the decision-making process. Qualitative research methods were used to examine attitudes towards clinical research and assess the video on content objectives, clarity of concept, and appropriateness for a pediatric audience. Following production, students from the 2017–2018 advisory board viewed the final video and presurvey and postsurvey were administered to assess the effect of video on the comprehension of 8 key concepts of informed consent on a 5-point Likert scale. The Wilcoxon signed-rank test was used to compare median pretest and post-test ranks. Results of this analysis were reviewed in seminar and students provided written contribution to this abstract. RESULTS/ANTICIPATED RESULTS: In total, 11 Walter Payton high school students participated in video development and 27, who were naïve to development, participated in the pre and post evaluation sessions. Students ranged from Freshman to Seniors and reflected the diverse ethnic and racial background of Chicago. A positive change from pre to post-test survey was observed in all questions presented assessing comprehension of key concepts of informed consent. The median post-test ranks were statistically significantly higher than the median pre-test ranks for all questions (p<0.01 in all). DISCUSSION/SIGNIFICANCE OF IMPACT: Chicago KIDS youth advisors were engaged in all aspects of the design of the research tool and gained experience in stakeholder contribution from study design to evaluation and publication. The students will next be involved in the design of a prospective randomized study to test the efficacy of the video compared with standard recruitment and consent practices. Given the difficulty of recruiting youth for clinical trials, development of effective engagement practices in is critically important. Our findings demonstrate the feasibility of utilizing youth advisors in a public school based setting.

OBJECTIVES/SPECIFIC AIMS: This case-control study aims to determine the relationships among childhood adversity, attachment style, and the likelihood of accepting or declining a referral for HV. The study will serve as a pilot to inform the power analysis of a subsequently proposed full-scale study. METHODS/STUDY POPULATION: Using a case-control study design, 25 women who decline HV referral (cases) will be compared with 25 women who accept HV referral (controls) on their exposure to childhood adversity and attachment style. Women who are eligible for the study are English-speaking mothers who have been offered HV services by Health Care Access Maryland. Surveys are administered in-person, either in the participant’s home or at another location (e.g., public library), based on participant preference. The dependent variable is participant’s verbal response to the HV referral (accept/decline). The independent variable, childhood adversity, will be measured using the Philadelphia Urban Adverse Childhood Experiences (ACEs) Survey and the Attachment Style Questionnaire (ASQ). Control variables include demographics (i.e., age, race, education, employment, housing, marital status), obstetric history (i.e., previous preterm birth, miscarriage, fetal death, infant death, abortion), and current psychosocial risk factors (i.e., history of substance use, intimate partner violence, depression). Descriptive comparisons will be done for the independent and control variables in controls versus cases. Bivariate analysis will examine associations between the odds of being a case and ACE score and ASQ score. Multivariate logistic regression models will be used to examine the relationship between ACE total and ASQ score; exposure to ACE in cases versus controls; and the odds of an avoidant and anxious attachment styles in cases versus controls. RESULTS/ANTICIPATED RESULTS: We hypothesize that (a) higher ACE scores will be positively associated with a higher level of avoidant attachment; (b) higher ACE scores will be positively associated with declining a HV referral; and (c) higher levels of avoidant attachment will be associated with declining a HV referral. DISCUSSION/SIGNIFICANCE OF IMPACT: Racial inequities in birth outcomes are pervasive and unjust. Non-Hispanic Black women experience births that result in infant mortality, fetal mortality, preterm birth, and low birth weight babies at more than double the rate of non-Hispanic White women in Baltimore and nationally. Prenatal and early childhood home visiting programs have been found to decrease maternal smoking and hypertensive disorder which are associated with PTB, reduce closely spaced births which is associated with fetal and infant death, and improve women’s long-term economic self-sufficiency, child health and social outcomes. However, as community-based programs, these services are not reaching the majority of eligible women in low-income urban settings—women who are also disproportionately burdened with poor pregnancy-related health outcomes. Considering the potential to improve outcomes, the importance of eliminating health disparities, and the national and local investment in HV services, it is vital to understand why some women are not enrolling in prenatal HV programs. The findings from this and subsequent studies will inform the translation of evidence-based HV program outreach efforts for women with complex social history. It will inform the design of enhanced outreach and engagement efforts of HV programs to more reliably engage women.

OBJECTIVES/SPECIFIC AIMS: The objective of this research was to investigate the effect of alcohol and evocative stimuli on heart rate variability (HRV) in partners with a history of intimate partner violence in a placebo-controlled alcohol administration study with an emotion-regulation task. METHODS/STUDY POPULATION: In total, 17 partners (9 females, 8 males) with a history of partner violence participated in a placebo-controlled alcohol administration study with an emotion-regulation task during which HRV measures were collected. In the alcohol condition, participants were administered a mixture of 100 proof vodka and cranberry juice calculated to raise their blood alcohol concentration (BAC) to 0.08%. In the placebo condition, participants consumed a volume of juice equivalent to that consumed in the alcohol condition, but without alcohol. Alcohol and placebo conditions were counter-balanced across participants as were the presentation the blocks of evocative and neutral partner stimuli. RESULTS/ANTICIPATED RESULTS: Controlling for baseline HRV, there was a significant main effect of stimuli (evocative vs. neutral partner stimuli) on HRV in intoxicated partners, F1,16=16.28, p=0.004. There was also a significant main effect of regulation on HRV under conditions acute alcohol intoxication, F1,16=23.55, p=0.001. These effects tell us that intoxicated partners experienced reduced HRV when exposed to evocative stimuli from their partners. These effects also tell us that under acute alcohol intoxication, partners were less able to regulate their emotion when exposed to evocative stimuli than when they consumed a placebo beverage. DISCUSSION/SIGNIFICANCE OF IMPACT: These results suggest that increases in intimate partner violence under acute alcohol intoxication may be the result of reduce HRV. This reduction in HRV would contribute to partners’ inability to response with adaptively in conflict when intoxicated. They also suggest that HRV may be an important target for intervention with partner with a history of intimate partner violence. One method may be Heart Rate Variability Biofeedback which has been shown to increase parasympathetic nervous system functioning, autonomic stability, and emotion regulation.

OBJECTIVES/GOALS: Waiting for psychotherapy is a major barrier to care and associated with negative outcomes. Individuals waiting for treatment may be particularly well-suited to receive low-intensity treatments (LITs), but few providers recommend LITs. We investigated provider-identified barriers to recommending LITs for patients on treatment waiting lists. METHODS/STUDY POPULATION: We recruited mental health professionals via social media and professional association listservs to participate in a brief survey. Participants were asked about their current waiting list practices and attitudes towards low-intensity resources for patients waiting for treatment. Participants were prompted to provide additional thoughts on recommending LITs for patients on waiting lists in an open-ended text box. Two members of the research team independently coded responses into themes, resolved discrepancies, and achieved total consensus. RESULTS/ANTICIPATED RESULTS: 141 mental health providers participated in the survey, and 65 (46%) provided a response to the open-ended question. The emerging themes included: Patient Barriers, Research Evidence/Efficacy, Feasibility, Patient Personal Contact, Patient Appropriateness, Liability, Systemic Problems, Trust in Programs, Downplaying Distress, Additional Resources, and Positive Attitudes. Providers were particularly concerned with giving a generalized intervention without having conducted a full evaluation or assessment with a patient. Many providers also reported concerns pertaining to the legal and ethical liability of providing LITs when a patient is not being seen face-to-face by a provider. DISCUSSION/SIGNIFICANCE: Many of the themes we identified parallel those identified in previous literature. Some barriers we identified from our providers, when thinking about integrating LITs on waiting lists, highlight the need for professional guidelines to address legal and ethical liability, as well as billing and reimbursement procedures.

OBJECTIVES/SPECIFIC AIMS: Tissue engineered tracheal grafts (TETG) could provide a life-saving cure for children with long segment airway defects. Computational fluid dynamics (CFD) is a novel and promising technique used to evaluate TETG performance. This pilot study examines the correlation of objective CFD simulations with subjective respiratory symptoms in a TETG large animal model. METHODS/STUDY POPULATION: Three-dimensional geometries of 1 TETG implanted sheep trachea were reconstructed from serial fluoroscopic images, allowing analysis with CFD simulations. Peak flow velocity (PFV) and peak wall shear stress (PWSS) across the graft as well as changes secondary to stenting were determined. CFD metrics were compared with respiratory symptoms seen on exam. RESULTS/ANTICIPATED RESULTS: Two weeks after implantation, the animal developed respiratory distress, which correlated with PFV and PWSS elevations. Although the intraluminal graft appearance changed minimally after dilation, PFV and PWSS decreased across the graft (4.5–0.8 m/s and 0.9–0.1 Pa, respectively). Long-term TETG stenting with dilation returned PFV and PWSS to baseline (0.8–0.3 m/s and 0.1–0.01 Pa, respectively), which correlated with immediate symptom resolution. DISCUSSION/SIGNIFICANCE OF IMPACT: CFD is a noninvasive modality, which allows the evaluation of airflow metrics of symptomatic TETG recipients. This diagnostic tool will permit planned interventions and graft design optimization.

OBJECTIVES/SPECIFIC AIMS: 1. Foster a community of scholars – by centering on training and professional development programs that assist with career progression. 2. Improve heath equity for the community – by developing innovative ways to capture data, address problems, deliver solutions, and disseminate results to patients and people everywhere. 3. Facilitate interdisciplinary teams at all career stages – by providing opportunities for researchers, regardless of discipline and career stage, to engage in dialogue with others.

Leveraging existing programs, like Project Panels, and offerings including a Specific Aims Workshop, K and R Writing Groups, and Mock Study Section, the SCOR extends the engagement of scholars in their ongoing research development. METHODS/STUDY POPULATION: Using quantitative methods, we have conducted surveys to measure effectiveness of weekly didactic sessions and topics. We use qualitative methods such as interviews and focus groups to better understand the relevance of the individual programs and the larger community of SCOR. RESULTS/ANTICIPATED RESULTS: N/A DISCUSSION/SIGNIFICANCE OF IMPACT: Creating a community of interdisciplinary investigators will greatly impact research at the institution.

OBJECTIVES/GOALS: Innovative educational approaches and training modalities are important for training a diverse workforce in the authentic skills needed to advance all phases of clinical and translational research. Endeavors to study and develop policies that promote the translational science spectrum are steeped in value judgments. Learning how to navigate moral ambiguity and ethical reasoning enlightens our understanding of stakeholder obligations, roles and responsibilities. Ethics education can be challenging if learners are insufficiently engaged in the necessary critical reflection. In this course, decision-making in public health is informed through the analysis of the ethical issues, developing alternative courses of action and providing justification for actions taken in response to real-world dilemmas. The course is provided to students with a variety of backgrounds (science, health, policy) in a Master of Public Health degree program. Course objective were to: 1) Identify ethical issues in public health policy, practice, and research using appropriate concepts and terms; 2) Recognize the full spectrum of determinants of health and related information needed to resolve ethical conflicts in public health policy, practice, and research; 3) Present varied and complex information in written and oral formats; 4) Assess potential solutions to ethical conflicts in public health policy, practice, and research and 5) Decide ethical courses of action for public health policy, practice, and research. We adopted an open pedagogy as a guiding praxis to inform public health ethics discourse amongst our learners. In this way, learner agency was maximized to develop course materials within a generalized framework and shared with each other through the perspectives of each individual. The goal was to not only analyze complex ethical dimensions of public health issues but also gain insights into the disciplinary lenses of one’s peers. METHODS/STUDY POPULATION: Each week was divided into two sessions, a seminar and workshop. Course instructors introduce topics in a one-hour session and then allow students to decide what information is needed for a second session where the ethical issues of the topic will be discussed. Information-gathering tasks are then distributed amongst students in areas that are not their specialty, e.g. social history to be researched by learner with a biology background. The second session then involves the reporting back of background information by each student and a discussion of the ethical issues that arise. Through this process, the ability to communicate with others in different disciplines is supported, while exploring other disciplines and then engaging in ethical discussion and reasoning. Topics were introduced during the seminar session each week over the span of five weeks: 1) global public health, 2) disease prevention & control, 3) environmental & occupational public health, 4) resource allocation & priority setting and 5) research ethics. Learners were tasked with identifying the needed information to address the ethical, policy, and research aspects of the public health question(s) presented in these seminars. Students independently submitted resources they discovered to course instructors prior to the workshop. The following session began with a workshop where learners briefly presented their findings and deliberated on specific facets of the public health issue from that previous seminar while discussing a specific case. Students were assessed on their preparation (submission of identified resources), workshop presentation and participation. Research Preparation: In each seminar, the class decided what key information would be required to support the discussion at the workshop, which revolved around a relevant case study on that week’s topic. Course instructors facilitated the groups identification of material to be researched and the delegation of tasks within the group. Each student submitted a summary document (template provided) to course instructors prior to class for their area of research related to the case. Research Presentation: At the beginning of each workshop, each student was asked to present the research work to the rest of the class so that everyone has the same information for the case study discussion. These short (5-10 minutes) presentations followed the format of the preparation summary. Participation/collaboration: Both the seminar and the workshop asked students to be active learners within the class, participating in discussion, strategizing for information-gathering tasks, presenting researched material and arguments to others, and participating in case study discussion. Participation was assessed in relation to the value of the contributions made by students. RESULTS/ANTICIPATED RESULTS: The open pedagogy allowed the learners to construct the necessary materials to discuss issues with each other and develop not only a deeper understanding of the ethical dimension of public health issues but a shared understanding of each other’s disciplinary lenses. Course feedback was generally very positive, with learners either agreeing (33%) or strongly agreeing (67%) that the course was effective overall. In asking what learners liked best about the course, some indicated the “open pedagogy learning style” and “I liked the discussion format.” The positive comments mostly highlighted the discussion format. Areas for improvement noted by the learners included wanting “a longer course to cover more topics” and that the material was covered in “too short a time frame.” Other comments included that the course “was a bit disorganized” or that “the discussions were not very structured.” While the discussions by their very nature were unstructured, there is opportunity to refine this pedagogy to find right balance of learner agency. DISCUSSION/SIGNIFICANCE OF IMPACT: The goal of this teaching method was to empower the learner with the important critical thinking skills to navigate challenging ethical dilemmas in public health they may encounter in their careers. These skills include the identification of the ethical or moral conflict(s), collecting the necessary information to examine/resolve the dilemma, think creatively about the information that is unavailable and how to discuss/disseminate information to a broad constituency. This an educational model that is easily adaptable for learners working in other areas of the translational research spectrum, e.g. basic, pre-clinical, clinical and implementation sciences.

OBJECTIVES/GOALS: 1) Characterize racial differences in congestive heart failure care delivery. 2) Examine the extent to which specific clinical roles were associated with improved care outcomes (i.e., hospitalizations, readmissions, days between readmissions, and charges) of African Americans (AA) with CHF. METHODS/STUDY POPULATION: EMR data was extracted from the Arkansas Clinical Data Repository (AR-CDR) on patients (ages 18-105) who received care between January 1, 2014 and December 31, 2021. Variables included age, sex, race, ethnicity, rurality, clinical diagnosis, morbidities, medical history, medications, heart failure phenotypes, and care delivery team composition. Binomial logistic regression ascertained the effects of these variables on patient’s care outcomes. A Mann Whitney-U test identified racial differences in outcomes. Psychometrically, classical test theory and item response theory assessed items for the risk surveillance tool. RESULTS/ANTICIPATED RESULTS: The study identified 5,962 CHF patients who generated 80,921 care encounters. The results revealed the disproportionate impact of CHF prevalence, hospitalizations, and readmissions on AAs. AAs had a significantly higher number of hospitalizations (i.e., 50% more) than Caucasians. Specific clinical roles (i.e., MDs, RNs, Care Managers) were consistently associated with 30% or greater decrease in odds of hospitalization and readmission, even when stratified by heart failure phenotype. Classical test theory results (e.g., Cronbach’s alpha; 0.88) indicated the set of items on the risk surveillance tool accurately reflect a patient risk for improved outcomes. DISCUSSION/SIGNIFICANCE: The findings stimulate the need for 1) EHR-based tools that manage care delivery equity and 2) investigations of specific clinical roles in risk stratifying and operationalizing the care plans of AAs, advancing formal access-to-care frameworks by ensuring access to clinical roles that are associated with improved outcomes.

ABSTRACT IMPACT: The Hispanic Alliance for Clinical and Translational Research Professional Development Core (PDC) will contribute to the improvement of the health of an increasing US Hispanic population, by supporting and training a new cadre of Hispanic/Latino CTR researchers and community leaders that understand this population’s prevalent health needs. OBJECTIVES/GOALS: To use the Professional Development Core (PDC) of the Hispanic Alliance for Clinical and Translational Research (Alliance) as a hub that coordinates training, mentoring programs, and grant support to address the need for more underrepresented minorities (URM) in clinical and translational research and mentoring. METHODS/STUDY POPULATION: PDC will: (1). Coordinate and offer an effective educational program based for new and mid-career researchers to address the gaps in research competencies on Hispanic/Latino health and healthcare through web-based asynchronous distance training, enhanced with face-to-face interactions. (2). Establish a robust mentoring program to address the mentoring gap for URM faculty by developing mentorship skills of faculty and researchers through a variety of resources, and offering protected time to mentor-mentee teams. (3). Design and implement a tailor-made curriculum to train scientists and community partners jointly, enabling them to carry out multidisciplinary research responsive to the Hispanic/Latino community health’s needs. RESULTS/ANTICIPATED RESULTS: From 2010 to 2019 the PDC supported over 1,000 researchers and faculty and provided 52 activities over the 9 years. PDC-supported researchers submitted 56 proposals and 21 grants (37.5.%) were awarded, for a total of $2, 225,751.00, and to published 94 peer-review papers. We expect that through Alliance PDC will sponsor at least 20 new trainees/mentees in Clinical and Translational Research (CTR), 20 new certified mentors, a continuous support program, and an increase of 30% in the scientific productivity (e.g., grants submission and peer-reviewed publications) of the Hispanic CTRs in Puerto Rico and the establishment of long-term links with the Hispanic community in Puerto Rico and across the United States to address its health needs. DISCUSSION/SIGNIFICANCE OF FINDINGS: The PDC programs are significant in addressing the need for qualified researchers and mentors that understand, have the know-how, and are interested in addressing the health needs of a growing USA Hispanic medically underserved population.
