OBJECTIVES/GOALS: In 2021, Frontiers CTSI revamped its evaluation infrastructure to be comprehensive, efficient, and transparent in demonstrating outputs and outcomes. We sought to build a platform to standardize measures across program areas, integrate continuous improvement processes into operations, and reduce the data entry burden for investigators. METHODS/STUDY POPULATION: To identify useful metrics, we facilitated each Core’s creation of a logic model, in which they identified all planned activities, expected outputs, and anticipated outcomes for the 5-year cycle and beyond. We identified appropriate metrics based on the logic models and aligned metrics across programs against extant administrative data. We then built a data collection and evaluation platform within REDCap to capture user requests, staff completion of requests, and, ultimately, request outcomes. We built a similar system to track events, attendance, and outcomes. Aligning with other hubs, we also transitioned to a membership model. Membership serves as the backbone of the evaluation platform and allows us to tailor communication, capture demographic information, and reduce the data entry burden for members. RESULTS/ANTICIPATED RESULTS: The Frontiers Evaluation Platform consists of 9 redcap projects with distinct functions and uses throughout the Institute. Point-of-service collection forms include the Consultation Request Event Tracking. Annual Forms include a Study Outcome, Impact, and Member Assessment Survey. Set timepoint collections include K & T application, Mock Study Section, and Pilot grant application submission, review, and outcomes. Flight Tracker is used to collect scientific outcomes and integrated with the platform. Using SQL, the membership module has been integrated into all forms to check and collect membership before service access and provide relevant member data to navigators. All relevant data is then synched into a dashboard for program leadership and management to track outputs and outcomes in real-time. DISCUSSION/SIGNIFICANCE: Since the launch of the evaluation platform in Fall 2022, Frontiers has increased its workflow efficiency and streamlined continuous improvement communication. The platform can serve as a template for other hubs to build efficient processes to create comprehensive and transparent evaluation plans.

ABSTRACT IMPACT: As technologies emerge at an increasing pace, the product developed through this work will guide rural health experts through a repeatable method of technology evaluation and selection at a faster and more reliable pace than otherwise possible. OBJECTIVES/GOALS: New technologies are emerging at an increasing pace, which leads to the question: ‘how is one to select a specific technology for their research?’ In response, this project endeavored to develop a technology evaluation and selection framework for rural health researchers. METHODS/STUDY POPULATION: The approach selected for this project included three phases. Phase one was to gain an understanding of rural health challenges, health-related emerging technologies, and rural health resources. Phase two involved using the information from phase one to select and adapt a set of technology foresight and forecasting analysis tools to be compiled within a framework. The third phase of the project was to prototype the framework, obtain researcher feedback, and iteratively implement improvements. Recommendations for the future of the framework were also developed during the third phase. RESULTS/ANTICIPATED RESULTS: The resulting product is the ‘Rural Health: Evaluation and Selection of Technology (RHEST) Framework.’ The RHEST Framework is a guide made available to use to aid in technology selection during the development of a new rural health project. The framework guides researchers through various stages, including ideation, analysis, and decision. Technology analysis tools are introduced in each stage, with links to additional information. The guide also contains a resource catalog for quick information look-up to find data sources, funding opportunities, and expert connections. Quantitative and qualitative data captured indicate that the product would add value for rural health researchers. DISCUSSION/SIGNIFICANCE OF FINDINGS: The initial version of the RHEST framework is limited in value because it is a static document and the primary audience are researchers. The value potential could improve considerably, however, if the framework were expanded to be a dynamic resource available to rural health care providers.

OBJECTIVES/GOALS: Rising rates of youth obesity, diabetes, depression, and anxiety necessitate programs that address physical and mental health concurrently. We describe a feasibility study for DiscoverU, an afterschool mentoring program that integrates multiple aspects of health including social emotional learning, physical activity, and mindful eating. METHODS/STUDY POPULATION: Trained college students mentored middle and high school students in a Midwestern school district. DiscoverU was delivered 2 hours, 2 days/week for 8 weeks. Based on self-determination theory, DiscoverU was designed to meet National Afterschool Association healthy eating and physical activity and social emotional learning standards. We assessed feasibility with participant attendance (middle, high school, and college students) and acceptability through qualitative data from participants and relevant stakeholders regarding facilitators/barriers to program implementation. We observed indicators of mentoring, lesson fidelity, and assessed physical activity using accelerometry. Pre-post surveys measured self-realization, self-regulation, mindful eating, and physical activity self-efficacy. RESULTS/ANTICIPATED RESULTS: We expect DiscoverU to be feasible and well accepted. We anticipate attendance will be similar or higher than that of other afterschool programs in the district. From focus groups we expect to hear a variety of factors that facilitate/prevent program engagement and learn about the acceptability of specific lessons. We expect to gain insight on processes and procedures from school stakeholders that will inform the sustainability of DiscoverU. We expect program fidelity to be high and mentoring skills to improve over the course of the program. We anticipate the majority of participants will meet National Afterschool Alliance physical activity guidelines. Preliminary outcomes of self-determination, self-regulation, mindful eating, and physical activity self-efficacy are expected to improve over the program. DISCUSSION/SIGNIFICANCE: Findings will help determine the readiness of DiscoverU to be scaled to other schools. A subsequent randomized effectiveness study will evaluate DiscoverU’s impact on intervention mechanisms (e.g., self-determination, self-efficacy) as well as on physical activity, diet, weight, and depression/anxiety symptomology.

OBJECTIVES/GOALS: Aims 1&2: Develop (1) and implement (2) online, guided self-help intervention for ED psychopathology and weight reduction. Aim 3: Follow-up to track remission of ED psychopathology and symptoms and WL maintenance at end of treatment and 6-months. METHODS/STUDY POPULATION: N = 60 college students meeting criteria (clinical/sub-clinical binge-type ED with BMI > 25) will complete a baseline survey and then will be randomized into a condition. Students in the intervention group (n = 30) will be offered 8 weeks of an online, guided self-help intervention for ED and WL. Students in the control group (n = 30) will receive an email message to seek support from Student Health Services. All participants will receive follow-ups 9 weeks and 6 months after baseline. Data analysis will compare Eating Disorder Examination Questionnaire (EDE-Q) scores and WL (change in BMI) at all three time-points. Group comparisons will be assessed via two-way mixed-model ANOVA. RESULTS/ANTICIPATED RESULTS: Recruitment is still ongoing. Data collected by the time of the conference will be presented on the poster. DISCUSSION/SIGNIFICANCE OF IMPACT: Online, guided self-help interventions have been used for WL, as well as for treatment of EDs separately, but no program exists to manage these commonly comorbid conditions concurrently. Thus, this pilot study will examine the effectiveness of combined programs to breach this treatment gap.

OBJECTIVES/SPECIFIC AIMS: More men than women develop urinary stones and their prevalence alters in women with menopause suggesting a steroidal influence. In men the incidence of stones is highest during July and August suggesting that environmental factors such as Vitamin D (VitD), a steroid, may affect stone formation. Previous studies have found differences in the development of stones between men and women; however, the reasons for sex differences in stone formation and type remain unclear. METHODS/STUDY POPULATION: We examined VitD levels in men and women (n = 18,753) that had no diseases based on a lack of an ICD-9 or ICD-10 code in their electronic medical record. We found that normal, healthy women had significantly higher levels of sera VitD compared to men (p = 6x10-6). We then examined whether sex differences existed for key endpoints/data from the Mayo Clinic Urinary Stone Disease (USD) Registry, which has around 1,600 urinary stone patients that are well-phenotyped according to sex, age and stone type. RESULTS/ANTICIPATED RESULTS: Control women were found to have higher sera VitD levels than men, but the sex difference no longer exists in kidney stone disease patients. When we further separated by race, we found that differences in VitD levels reappeared; this suggests that race also plays a role in sera VitD variances. DISCUSSION/SIGNIFICANCE OF IMPACT: We are developing a disease severity score, which we will use to correlate to sera VitD levels in patients according to sex, age and race. Future analyses will take into account whether subjects had VitD and calcium supplementation. This project begins to explore the mechanism behind the sex differences known to exist in urinary stone disease, which is critically needed to provide improved diagnosis and therapy for this debilitating disease.

OBJECTIVES/GOALS: Immunomodulatory drugs (IMiDs) are critical to multiple myeloma (MM) disease control. IMiDs act by inducing Cereblon-dependent degradation of IKZF1 and IKZF3, which leads to IRF4 and MYC downregulation (collectively termed the “Ikaros axis”). We therefore hypothesized that IMiD treatment fails to downregulate the Ikaros axis in IMiD resistant MM. METHODS/STUDY POPULATION: To measure IMiD-induced Ikaros axis downregulation, we designed an intracellular flow cytometry assay that measured relative protein levels of IKZF1, IKZF3, IRF4 and MYC in MM cells following ex vivo treatment with the IMiD Pomalidomide (Pom). We established this assay using Pom-sensitive parental and dose-escalated Pom-resistant MM cell lines before assessing Ikaros axis downregulation in CD38+CD138+ MM cells in patient samples (bone marrow aspirates). To assess the Ikaros axis in the context of MM intratumoral heterogeneity, we used a 35-marker mass cytometry panel to simultaneously characterize MM subpopulations in patient samples. Lastly, we determined ex vivo drug sensitivity in patient samples via flow cytometry. RESULTS/ANTICIPATED RESULTS: Our hypothesis was supported in MM cell lines, as resistant lines showed no IMiD-induced decrease in any Ikaros axis proteins. However, when assessed in patient samples, Pom treatment caused a significant decrease in IKZF1, IKZF3 and IRF4 regardless of IMiD sensitivity. Mass cytometry in patient samples revealed that individual Ikaros axis proteins were differentially expressed between subpopulations. When correlating this with ex vivo Pom sensitivity of MM subpopulations, we observed that low IKZF1 and IKZF3 corresponded to Pom resistance. Interestingly, most of these resistant populations still expressed MYC. We therefore assessed whether IMiD resistant MM was MYC dependent by treating with MYCi975. In 88% (7/8) of patient samples tested, IMiD resistant MM cells were sensitive to MYC inhibition. DISCUSSION/SIGNIFICANCE: While our findings did not support our initial hypothesis, our data suggest a mechanism where MYC expression becomes Ikaros axis independent to drive IMiD resistance, and resistant MM is still dependent on MYC. This suggests targeting MYC directly or indirectly via a mechanism to be determined may be an effective strategy to eradicate IMiD resistant MM.

OBJECTIVES/GOALS: Recent research has attempted to identify diagnostic, prognostic, and predictive biomarkers, however, currently, no biomarkers can accurately diagnose GBC and predict patients prognosis. Using machine learning, we can utilize high-throughput RNA sequencing with clinicopathologic data to develop a predictive tool for GBC prognosis. METHODS/STUDY POPULATION: Current predictive models for GBC outcomes often utilize clinical data only. We aim to build a superior algorithm to predict overall survival in GBC patients with advanced disease, using machine learning approaches to prioritize biomarkers for GBC prognosis. We have identified over 80 fresh frozen GBC tissue samples from Rochester, Minnesota, Daegu, Korea, Vilnius, Lithuania, and Calgary, Canada. We will perform next-generation RNA sequencing on these tissue samples. The patients clinical, pathologic and survival data will be abstracted from the medical record. Random forests, support vector machines, and gradient boosting machines will be applied to train the data. Standard 5-fold cross validation will be used to assess performance of each ML algorithm. RESULTS/ANTICIPATED RESULTS: Our preliminary analysis of next generation RNA sequencing from 18 GBC tissue samples identified recurrent mutations in genes enriched in pathways in cytoskeletal signaling, cell organization, cell movement, extracellular matrix interaction, growth, and proliferation. The top three most significantly altered pathways, actin cytoskeleton signaling, hepatic fibrosis/hepatic stellate cell activation, and epithelial adherens junction signaling, emphasized a molecular metastatic and invasive fingerprint in our patient cohort. This molecular fingerprint is consistent with the previous knowledge of the highly metastatic nature of gallbladder tumors and is also manifested physiologically in the patient cohort. DISCUSSION/SIGNIFICANCE: Integrative analysis of molecular and clinical characterization of GBC has not been fully established, and minimal improvement has been made to the survival of these patients. If overall survival can be better predicted, we can gain a greater understanding of key biomarkers driving the tumor phenotype.

OBJECTIVES/SPECIFIC AIMS: To develop a KL2 curriculum on the science and art of drug formulation. METHODS/STUDY POPULATION: Develop training materials for KL2 scholars that outline the art of formulation development. Materials will include syllabi, reading materials, and course work. RESULTS/ANTICIPATED RESULTS: This will enhance the training of KL2 scholars by incorporating formulation development concepts into their human health enhancing research projects. DISCUSSION/SIGNIFICANCE OF IMPACT: For new chemical entities, formulation goals must be realistic and move along in a step-wise manner from the laboratory bench, through toxicology studies, and on to Phase 1 studies. By training scholars in phase-specific formulation goals, their interactions with funding agencies, formulation scientists, and regulators will be more efficient, productive, and successful. For those scholars who are working to improve existing treatments, introducing the concept of formulation improvements that can create new indications, or improve efficacy, safety and patient compliance will open up more possibilities for creative product development.

OBJECTIVES/GOALS: AA are over-represented on the waitlist for kidney transplant and are often unaware of how waitlist acceptance practices differ across transplant programs and influence access to transplant. We will develop a culturally sensitive transplant program report card to communicate these variations. METHODS/STUDY POPULATION: Scientific Registry of Transplant Recipients (SRTR) data will be used to identity clinical factors strongly associated with AA access to transplant. Interviews and focus groups with AA kidney transplant candidates and their families will collect feedback on the SRTR report card and inform the development of the culturally sensitive report card. Additional focus groups will evaluate its effect on knowledge and medical decision making. We will collaborate with the stakeholders, including AA transplant candidates and their families, transplant programs, SRTR, and providers, to identify strategies to disseminate the report card in the AA community RESULTS/ANTICIPATED RESULTS: To date, no investigation has systematically collected feedback on the SRTR transplant program report card from AA candidates to ensure that the tool is accessible and effective in the AA community. We hypothesize that a culturally sensitive report card will improve AA candidates’ knowledge of program factors that impact access to transplant and enable informed decisions about where they pursue a transplant evaluation. The results of this study have the potential to change how AA patients are counselled while seeking transplantation. DISCUSSION/SIGNIFICANCE OF IMPACT: A culturally sensitive report card can reach more AA patients and enable more informed decision making by providing education about differences in transplant programs that may impact their access to transplant. In the future, we will design a trial to evaluate the prototype.

OBJECTIVES/SPECIFIC AIMS: Discuss ethical and policy issues that will impact clinical research. Raise awareness of the need to understand internal policies at home institutions Encourage further examination of ways to facilitate clinical research participation. METHODS/STUDY POPULATION: Ethical and policy analysis. RESULTS/ANTICIPATED RESULTS: Ideally, clinical research participants should not be required to pay to participate in research. However, if we go with an equity model, as opposed to an equality model, policies should be changed to allow equal access to research participation. This is a matter of justice and also will enhance the quality of the science. DISCUSSION/SIGNIFICANCE OF IMPACT: Unless steps are taken to make participation in clinical research less burdensome financially for participants, research may slow or results may be biased, because only those who can pay will be able to participate.

OBJECTIVES/GOALS: Rib fractures are common traumatic thoracic injuries and are associated with high rates of morbidity and mortality. In those age ≥ 65, the rate of these complications double. This study sought to identify the extent to which injury-related predictors influence clinical outcomes in geriatric patients with rib fractures. METHODS/STUDY POPULATION: A retrospective 5-year review was performed of a single Level 1 Trauma center registry. Geriatric patients (≥65 years of age) diagnosed with rib fractures from January 1, 2014 to December 31, 2019 were included. The primary outcome of interest was in-hospital mortality. Secondary outcomes included hospital and intensive care unit length of stay (HLOS and ICU LOS, respectively) and discharge disposition, as a surrogate for loss of independence. Further, subgroup analysis based on number of rib fractures (i.e. <4 and ≥4 rib fractures) was performed. RESULTS/ANTICIPATED RESULTS: 2,134 adult trauma patients were admitted with at least one rib fracture. Of these, 1,037 (49%) were ≥ 65 years old. This cohort had a mean age of 78.6 years old, injury severity score (ISS) of 11.4, HLOS of 7.4 days and 29% required ICU care with mean ICU LOS of 1.9 days. Only 36% were discharged home compared to 64% who were discharged to a care facility and thus had a loss of independence. Overall mortality was 6.3%. Compared to survivors, non-survivors had a higher ISS (19.3 vs. 10.8, p = < 0.0001) and longer ICU LOS (7.1 vs. 6.5 days, p = 0.04). Analysis based on number of rib fractures showed that those with ≥4 rib fractures had significantly higher mortality (8% vs. 4%, p = 0.008), longer HLOS (8.7 vs. 6.1 days, p < 0.0001), longer ICU LOS (2.6 vs. 1.3 days, p < 0.0001), and significantly lower discharge to home (32% vs. 39%, p = 0.02). DISCUSSION/SIGNIFICANCE: To our knowledge, this is the largest single-center study of geriatric patients with rib fractures. In this study, the observed mortality in patients ≥65 years of age was 6.3% which represents a lower mortality rate than historically reported. Despite this, only 36% were able to be discharged directly to home.

OBJECTIVES/SPECIFIC AIMS: The off-target and organ-specific toxicities observed in cancer immunotherapy present an obstacle to T-cell-based therapeutics. A recent clinical trial underscored the need for improved methods to define TCR specificity after melanoma patients treated with TCR engineered T-cells suffered from fatal cardiovascular toxicity arising from the unpredicted recognition of a muscle-specific peptide. METHODS/STUDY POPULATION: To address this drawback to T-cell-based immunotherapies, we developed a novel protein engineering approach to define the peptide specificity of a given TCR. Here, directed evolution in a yeast display system produced a large scale peptide library, where recognition by the melanoma reactive DMF5 TCR acted as the guiding selective pressure. After this technique identified a panel of putative cross reactive peptides, sequence analysis and computational modeling followed by kinetic binding experiments and structural analysis determined the DMF5 TCR recognizes 2 distinct classes of peptides through chemically distinct mechanisms. RESULTS/ANTICIPATED RESULTS: This information led to the rational, structure-based design of additional cross reactive peptides and introduced a unique approach to screen the human proteome and identify the TCR targets which triggered undesired autoimmunity when this molecule was used in clinical trials. DISCUSSION/SIGNIFICANCE OF IMPACT: The distinct chemical nature of the 2 peptide classes suggest TCRs are more cross reactive than previously thought, presenting an obstacle to cell-based immunotherapy. Defining the peptide specificity of TCRs is of high interest to the immunology community, and will lead to improved approaches to designing engineered TCRs for cell therapy.

OBJECTIVES/SPECIFIC AIMS: In this study, we aim to describe temporal trends in opioid abuse among adolescents and 11-21years and young adults 22-35years with Sickle cell disease hospitalized for sickle cell crisis. We also aim to evaluate clinical and healthcare utilization outcomes of opioid abuse in the same population. In addition, we hope to assess for difference in effect by age category. METHODS/STUDY POPULATION: Our study is a cross-sectional study of data secondarily sourced from the 2007-2014 National Inpatient Sample(NIS), a component of the Healthcare Utilization Project (HCUP). Variables were identified using ICD-9-CM codes. We selected inpatient stays for patients aged 11-35 years admitted for sickle cell crisis. Opioid abuse was the primary outcome of interest. Secondary outcomes were inpatient mortality, total charge, length of stay and select clinical outcomes. We analyzed our data for trends and outcomes. We performed trend analysis of prevalence rates between 2007-2014 by age categories. Propensity-Matched Score regression models were deployed to assess for associations between opioid abuse and outcomes while adjusting for relevant covariates. Sub-group analysis of opioid abuse by age was assessed for outcomes of interest. Trend analysis was performed on Joinpoint Software v4.6.0, (National Cancer Institute, NIH, Bethesda, MD). Outcome analysis was performed on SAS v9.4 (SAS Institute, Cary, NC). Statistical significance was set at 95% and p-value of 0.05, two-tailed. RESULTS/ANTICIPATED RESULTS: Of 86,827 inpatients admitted for sickle cell crisis, 2,363 (2.73%) had a diagnosis of opioid abuse while 84,464 (97.27%)did not abuse opioids. 27,004 (31.01%) of admitted patients were 11-21 years while 59,823 (68.99%) were 21-35 years. We found statistically significant APCs (Annual Percentage Change) showing increasing trends in both age categories for years under review, (18.47% [95% CI 15.39-21.63]; p-value <0.001 in young adults vs. 10.31% [95% CI 3.58-17.49]; p-value 0.009 in adolescents). The difference in APCs between both age categories were also significant (−8.16% [95% CI [−14.26-2.05]; p-value 0.009). There were no parallelism or coincidence in the trend lines. Opioid abuse was found to be associated with significantly longer length of stay (7.74 vs 6.05 days), higher total charge ($40,797 vs $32,164), (aOR 1.44; 95% CI [1.19-1.75]) seizures, sepsis (aOR 1.62; 95% CI [1.35-1.94]) and pulmonary hypertension (aOR 1.36; 95% CI [1.12-1.66]). No significant association was found for inpatient mortality, transfusion, cardiac dysrhythmias, pulmonary embolism and acute kidney injury. Significant interaction existed between opioid abuse and age for total charge (for $41,869 vs $29,371 among adolescents & $40,632 vs $32,550 among young adults; interaction p-value 0.03). DISCUSSION/SIGNIFICANCE OF IMPACT: Trends show a significant increase in the prevalence of opioid abuse among adolescents and an increasingly higher prevalence when adolescents transition to young adults. Opioid abuse among sickle cell patients is associated with significant poor healthcare resource utilization and clinical outcomes. Public health interventions to prevent worsening opioid abuse prevalence are expected to improve patient outcomes.

OBJECTIVES/GOALS: To describe preliminary results of Alzheimer’s and dementia caregivers’ (CGs) mobile app use and intention to adopt mHealth apps for their own chronic condition self-management. To discuss implications for designing and implementing mHealth interventions for CGs. METHODS/STUDY POPULATION: This study aims to recruit 110 racially and ethnically diverse family caregivers (CGs) who have a chronic condition, provide care for persons with Alzheimer’s disease or related dementias, and have access to a mobile device. This is a cross-sectional correlational study collecting data with computer-assisted telephone interviews stored through REDCap. The study survey was created using existing surveys about mobile app use; relevant, well-validated research instruments; and questions from the U.S. Census and other national surveys. CGs are being actively recruited from the Baltimore-Washington metropolitan area using various recruitment strategies that have been effective in prior studies. RESULTS/ANTICIPATED RESULTS: The majority of CGs used websites (86%), mobile devices (68%) or apps (53%) to manage their own health. CGs using health-related apps were tracking their exercise (60%), diet (60%), medical records (50%), and physical health measures (50%). More than 4 out of 5 (82%) predicted they would use mobile apps to self-manage their chronic condition, though only 68% actually planned to use them. 86% of CGs were using mobile apps for non-health related purposes, with the most popular app being weather (90%), followed by social media (74%), music/entertainment (68%), and banking/business apps (63%). CGs used weather and social media apps most often (2 or more times/day) and spent 9 hours/week on apps. DISCUSSION/SIGNIFICANCE OF IMPACT: Websites and mobile apps appear to be feasible modes to deliver health interventions to CGs. Researchers should consider including features of apps most frequently used by CGs, such as the weather, ways to connect with others, and music/entertainment, when delivering mHealth interventions to CGs.

OBJECTIVES/GOALS: Minoritized populations experience a large burden of Alzheimer’s Disease; interventions are often delayed and underrepresented communities’ participation in clinical trial research is low. Lack of information has been proposed as a barrier to clinical research enrollment of minoritized populations. METHODS/STUDY POPULATION: Brain Train, a cluster randomization trial, evaluated the role of education in increasing willingness to participate in research. A 3 segment program was developed whereas segment 3 had two versions: clinical trial education or healthy brain aging video. Brain Train was presented to multicultural communities with participants of at least 50 y/o throughout WNY. The primary outcome measure is evaluating the percent change in responding yes to would you be interested in participating in a clinical trial? before and after segment 3. The secondary outcome measure and exploration of barriers are measured by a Research Attitude Questionnaire. Demographic information such as age, race, gender, socioeconomic status, and educational attainment is collected. The statistical model is a generalized linear mixed model. RESULTS/ANTICIPATED RESULTS: Sixteen sessions with 281 participants were completed to generate the pilot dataset. We see 59.29 % of individuals answered yes before segment 3 and 46.02% answered yes after the educational intervention. Our data shows there is a 13.3% decrease in clinical trial participation interest after the educational intervention. Through our RAQ responses, our data shows significance when it comes to our participants’answers to questions regarding society needing to devote more resources to medical research (p=0.04). Trust emerged as the most significant barrier when it comes to one’s willingness to participate in medical research and clinical trials (p=0.03). DISCUSSION/SIGNIFICANCE: Our preliminary results from the first sixteen events suggest that the power of education is not sufficient to overcome barriers to clinical trial participation for underrepresented communities. Instead, trust appears to be the most significant barrier. Trust building strategies should be explored to answer this research question.

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.

Within Wisconsin, our residents experience some of the worst health disparities in the nation. Public reporting on disparities in the quality of care is important to achieving accountability for reducing disparities over time and has been associated with improvements in care. Disparities reporting using statewide electronic health records (EHR) data would allow efficient and regular reporting, but there are significant challenges with missing data and data harmonization. We report our experience in creating a statewide, centralized EHR data repository to support health systems in reducing health disparities through public reporting. We partnered with the Wisconsin Collaborative for Healthcare Quality (the “Collaborative”), which houses patient-level EHR data from 25 health systems including validated metrics of healthcare quality. We undertook a detailed assessment of potential disparity indicators (race and ethnicity, insurance status and type, and geographic disparity). Challenges for each indicator are described, with solutions encompassing internal (health system) harmonization, central (Collaborative) harmonization, and centralized data processing. Key lessons include engaging health systems in identifying disparity indicators, aligning with system priorities, measuring indicators already collected in the EHR to minimize burden, and facilitating workgroups with health systems to build relationships, improve data collection, and develop initiatives to address disparities in healthcare.

The Advancing the Science of Mentorship: Future Directions for Sustainable Implementation and Evaluation of Mentorship Education for the Clinical and Translational Science Workforce conference was held in Madison, Wisconsin, in April 2023. The conference provided an engaging and scholarly forum for clinical and translational researchers from diverse backgrounds and career stages (including leaders at Clinical and Translational Science Award (CTSA) hubs and affiliated institutions) with a professional interest and commitment to improving and diversifying workforce development and fostering a climate of inclusive excellence through best practices in mentorship. Outcomes from the conference include an online resource and a new Community of Practice.

Racially and ethnically minoritized individuals, first-generation college students, and women are significantly underrepresented in science, technology, engineering, and mathematics (STEM) careers. This lack of equal representation limits creativity and progress in these fields and perpetuates systemic barriers that discourage students from pursuing STEM pathways. This special communication introduces the three-tiered mentorship model employed in the Teen Science Ambassador Program (TSAP), which incorporates senior mentors, near-peer mentors, and high school ambassadors (i.e., mentees) to promote education, hands-on research, and career development in STEM for underrepresented students. We discuss the benefits and challenges of the three-tiered model and offer recommendations for optimizing its effectiveness to enhance mentorship experiences for all participants. Findings from the TSAP program suggest that the three-tiered approach benefited all participants: high school ambassadors gained STEM skills and confidence, near-peer mentors developed leadership and communication abilities, and senior mentors improved mentorship skills. However, the effectiveness of near-peer mentorship is highly dependent on clearly defined roles and structured involvement. Thus, feedback collected from each mentorship tier was used to inform subsequent iterations of the program. The layered mentorship structure fostered a sense of community and belonging, which is crucial for retaining individuals from underrepresented groups in STEM.
