OBJECTIVES/SPECIFIC AIMS: This study aims to evaluate potentially traumatic events (PTEs) and its relationship with posttraumatic stress symptoms (PTSS), posttraumatic growth (PTG), and resilience in a sample of help-seeking individuals in Puerto Rico. METHODS/STUDY POPULATION: This is an analytic, cross sectional design. Adults receiving health services will participate in the study. Recruited participants will provide informed consent during a visit to a community mental health clinic or community hospital. They will complete a demographic document and four retrospective questionnaires about the variables of study. RESULTS/ANTICIPATED RESULTS: We expect that a high rate of potentially traumatic events (PTEs) is associated with an increased rate of posttraumatic stress symptoms (PTSS). We also expect that a high rate of PTSS is associated with an increased rate of posttraumatic growth (PTG). We expect that a high rate of resilience is associated with low rates of PTSS and PTG. DISCUSSION/SIGNIFICANCE OF IMPACT: This is a first step in the development of effective, clearly targeted interventions, specifically designed to treat negative effects, and also to facilitate positive change and resilience after PTE exposure.

OBJECTIVES/GOALS: Scaffolding aids learning by gradually removing assistance to encourage independence (Bickhard, 2013; Gross, 2015). Mightier is a commercially available biofeedback game that fosters emotion regulation (ER) skill practice through play. This study aims to evaluate the ability of Mightier to scaffold the learning of ER and reduce irritability. METHODS/STUDY POPULATION: Data were collected via online caregiver report. Inclusion criteria were age of child (<= 18 years) and study enrollment prior to the child engaging with Mightier. Children wear a heart rate (HR) monitor while playing games in the Mightier app library. As their HR increases, play becomes more difficult. Children can pause the game to use a scaffolded ER activity or regulate independently to return the game to normal difficulty levels. Caregivers were instructed to use the game ad libitum. Participants included caregivers of 195 children (Mage = 7.84 years old; range = 4-18 years old; 24.28% female; 74.57% male); the sample was predominantly White (56%). Caregivers completed the Affective Reactivity Index, a measure of their child’s irritability, before and after playing Mightier for 8-12 weeks. RESULTS/ANTICIPATED RESULTS: A first Wilcoxon Signed Rank Test revealed a significant reduction in the ratio of scaffolded cooldowns (using a guided activity to regulate) to total cooldowns on the first play day (Md =.50) versus the last play day (Md = .22), z = –6.51, p < .001. A second test revealed a statistically significant increase in the ratio of independent cooldowns (regulating on their own) to total cooldowns on the first play day (Md = .50) versus the last day of play (Md = .80), z = 6.34, p < .001. Given the significant, inverse relationships between scaffolded and independent ER on the first play day versus the last play day, further analyses will examine potential mediation and moderation effects of game engagement (play minutes, total cooldowns, scaffolded cooldowns, and independent cooldowns) on changes in irritability. DISCUSSION/SIGNIFICANCE: ER is vital for healthy development and protects against mental health challenges (LeBlanc etal., 2017). Across domains, scaffolded practice promotes learning (Vygotsky, 1978). Results reveal that scaffolded practice leads to independent ER during play. Future research should explore whether this pathway leads to independent ER outside of play.

OBJECTIVES/GOALS: Cannabis laws may impact cannabis and tobacco use, given high prevalence of co-use of these products among young adults (YAs). The objective of this study was to examine trends in YA any cannabis, blunt, cigarette, and cigar use from 2002-2018 in states that passed adult and medical use (AMU) or medical use only (MUO) cannabis laws during that time (N=16). METHODS/STUDY POPULATION: Using data from the National Survey on Drug Use and Health, we conducted a segmented regression analysis to calculate absolute percent change (APC) in past 30-day cannabis and tobacco use between time points. The National Cancer Institute’s Joinpoint software was used to also estimate points of inflection (Joinpoints) when the slope of a trend significantly (p<0.05) changes. Separate models were estimated for each state, with time as the independent variable measured in years. Up to three Joinpoints per model were allowed. The model with optimal Joinpoints was determined using a model selection criterion via a permutation test. Joinpoints and APCs were compared with key legalization dates to describe patterns within and across states with varying cannabis policies. RESULTS/ANTICIPATED RESULTS: Generally, the 16 states showed a steady decline in YA cigarette smoking over time, a slight decline in cigar smoking, and increases in cannabis and blunt use. AMU states had lower average 2018 prevalence of cigarette smoking than MUO states (18.3% vs. 21.5%) and higher cannabis use (32.3% vs. 21.3%). Cannabis use consistently increased following opening of MUO retail outlets. Generally, there appears to be a slight delay in cannabis use increases following AMU laws, and in some states temporary declines. For example, Washington experienced an initial decrease (-20.3%) following AMU passage (2012) then increase (+16.3%) after retail dispensaries opened in 2014. In AMU states, blunt use has surpassed cigar smoking, while in MUO states, the prevalence of blunt and cigar use is similar. DISCUSSION/SIGNIFICANCE: Introduction of cannabis laws are correlated with increases in YA cannabis and blunt use, with higher cannabis use in AMU states. Trends may also correlate other state political, economic, or social factors. Joinpoint regression can assess changes in a policy’s target behavior with no a priori assumptions regarding timing of policy effects.

OBJECTIVES/GOALS:

• A web interface that allows for easy upload of CSV text data to time-based visualizations

• Implementation of change points analysis to identify and display points where event rates increased or decreased

• customizable plots where the user can change point shapes, color, etc.

• customizable and advanced filtering support

• support for plot comparisons and exports

METHODS/STUDY POPULATION: We used the R/Shiny framework to develop a web application for visualization of time stamped data. The Research and Exploratory Analysis Driven Time-data Visualization (READ-TV) application allows for user-friendly mining for longitudinal patterns in data. READ-TV is built specifically for FD analysis, but is easily adaptable to other clinical use cases, as we allow for the use of general metadata on events and cases.The building of a quantitative framework for event analysis starts with the application of homogeneous Poisson processes, which relate the times of occurrence of events in terms of an underlying rate. To understand the changes in this underlying rate, changepoint analysis is used to model the rate as a function of time using piecewise constant approximations. The changepoint analysis allows us to identify the specific periods of time where the rate of FD is increased relative to a baseline or a desired operating range. RESULTS/ANTICIPATED RESULTS: READ-TV application allows for import of time stamped event data from multiple cases. Event and case metadata are supported to facilitate filtering and mining of interesting subsets of data. Stem plots are used for visualization of selected event timelines in chosen cases. This visualization is accompanied with summary of the number and estimates of rates of occurrence of specific event types (e.g. types of FD). Change-point analysis is implemented using the ‘changepoint‘ R library. These analyses allow the users to quickly understand whether the rates of events (FD) is changing across the case timeline and where exactly these changes are occurring. DISCUSSION/SIGNIFICANCE OF IMPACT: We have demonstrated the READ-TV application to the team of the AHRQ-funded Human Factors and Systems Integration in High Technology Surgery (HF-SIgHTS) study. The ability to visualize and perform quantitative analysis of the study data was received with unanimous positive feedback and enthusiasm. We continue READ-TV development focusing on (1) increased user-friendliness using the HF-SIgHTS as our focus group, (2) increased functionality, and (3) use of more general localization terminology to allow for other applications.

OBJECTIVES/SPECIFIC AIMS: The prevention, management, and treatment of HIV, STDs, and HCV requires continuous training that reflects contemporary best-practice and innovative care models. In order to improve the NYS AIDS Institute’s comprehensive web-enabled training program, which enhances the capacity of a diverse healthcare workforce, a needs assessment (NA) of our community of practice (CoP) is needed to better understand their training needs, circumstances, and instructional modalities preferences. The goal of the assessment was to better understand our CoP’s preferences of online trainings, and as a result to develop a “responsive design” system that will enhance user’s learning experience thus improving patient care. METHODS/STUDY POPULATION: We developed and deployed an NA survey using REDCap. The instrument consisted in 27 questions related to providers’ preferences on receiving continuing educational training and their use of technologies, including mobile platforms, online modules, webinars, and telehealth. As part of the recruitment strategy, several resources were deployed over a 1-month recruitment period including sequential email blasts, website promotion, and assessment links included in newsletters and social media. Weekly reminders were also used to promote the participation from our CoP. RESULTS/ANTICIPATED RESULTS: A total of 310 respondents participated in the NA, with 85.8% from NYS. 177 were clinicians (20.5% MD, 2.9% PA, 17.3% NP, and 16.3% RN) and 133 nonclinical providers (case/care managers, social workers, public health professionals, coordinators/administrators, and other). The participants worked in hospitals, community health centers, substance use centers, private practices, and state/local health departments. More than 90% of respondents indicated that they preferred both live/in-person and online training, and participants most strongly indicated that they stayed up-to-date on current developments through CDC, the AIDS Institute, and conferences. More than 60% of respondents considered that receiving CE credit for the training was very important and 28% indicated they would use training materials in Spanish if offered. In terms of technology, over 80% of the respondents preferred computers, but more 50% also used mobile devices (computer at home 61.8%, computer at work 85%, tablet 29.9%, iPhone 20.9%, Android 16.6%, other device 2.3%). DISCUSSION/SIGNIFICANCE OF IMPACT: Accessing an online CoP provided a useful opportunity to assess training needs and preferences of clinical and nonclinical providers. Most providers indicated that they were primarily likely to use a work computer to complete online training or secondarily a home computer. With a significant portion of respondents indicating use of tablets, smartphones, and other devices, online training opportunities should be developed with responsive design to assure flexibility and access. In addition to online training, participants indicated that they also strongly valued live, in-person training. Offering training with CDC and the NYS AIDS Institute branding, in Spanish, together with offering continuing education credit, were all seen as desirable training elements. Accessing this online CoP helped streamline and target training priorities and logistics.

OBJECTIVES/GOALS: Diverse medication-based studies require longitudinal drug dose information. EHRs can provide such data, but multiple mentions of a drug in the same clinical note can yield conflicting dose. We aimed to develop statistical methods which address this challenge by predicting the valid dose in the event that conflicting doses are extracted. METHODS/STUDY POPULATION: We extracted dose information for two test drugs, tacrolimus and lamotrigine, from Vanderbilt EHRs using a natural language processing system, medExtractR, which was developed by our team. A random forest classifier was used to estimate the probability of correctness for each extracted dose on the basis of subject longitudinal dosing patterns and extracted EHR note context. Using this feasibility measure and other features such as a summary of subject dosing history, we developed several statistical models to predict the dose on the basis of the extracted doses. The models developed based on supervised methods included a separate random forest regression, a transition model, and a boosting model. We also considered unsupervised methods and developed a Bayesian hierarchical model. RESULTS/ANTICIPATED RESULTS: We compared model-predicted doses to physician-validated doses to evaluate model performance. A random forest regression model outperformed all proposed models. As this model is a supervised model, its utility would depend on availability of validated dose. Our preliminary result from a Bayesian hierarchical model showed that it can be a promising alternative although performing less optimally. The Bayesian hierarchical model would be especially useful when validated dose data are not available, as it was developed in unsupervised modeling framework and hence does not require validated dose that can be difficult and time consuming to obtain. We evaluated the feasibility of each method for automatic implementation in our drug dosing extraction and processing system we have been developing. DISCUSSION/SIGNIFICANCE OF IMPACT: We will incorporate the developed methods as a part of our complete medication extraction system, which will allow to automatically prepare large longitudinal medication dose datasets for researchers. Availability of such data will enable diverse medication-based studies with drastically reduced barriers to data collection.

OBJECTIVES/SPECIFIC AIMS: Preterm birth rates have been rising in the United States, and reducing preterm birth is a high-priority clinical and public health concern. There are no existing strategies to reduce preterm birth in nulliparous individuals. The present study aims to evaluate prenatal care as a protective factor for preterm birth in this population. METHODS/STUDY POPULATION: Missouri birth record data for child birth years 1993-2016 were used to create a sample of 325,088 singleton births to nulliparous women, themselves born in MO 1975-1985. Logistic regressions, stratified by maternal race (White, African-American, Asian, American Indian/Alaskan Native, Other), were used to predict preterm birth (< 37 weeks gestational age) as a function of 1) initiation of prenatal care of by end of first trimester and 2) Adequacy of Prenatal Care Utilization Index, with sociodemographic covariates of child birth year, maternal age, highest educational level, and marital status (four level variable, including married yes/no, and partner named on birth record, yes/no). Subsequent analyses will use this logistic regression to create a propensity score predicting smoking during pregnancy using birth record parental sociodemographic characteristics, stratified by maternal race. Primary analyses will focus on the role of prenatal care in predicting smoking during pregnancy and preterm birth risk within propensity score stratum. Secondary analyses will consider the role of other risk factors, including maternal pre-pregnancy BMI and maternal DUI history, on preterm birth risk. RESULTS/ANTICIPATED RESULTS: Preliminary logistic regressions predicting preterm birth were analyzed, stratified by maternal race. In White mothers, preterm birth prevalence was 8.2%, and risk was significantly increased by maternal age ≤ 15 and ≥ 31, being unmarried, and by receiving no prenatal care, yet unaffected by timing of prenatal care initiation. For African-American mothers, preterm birth prevalence was 11.9%, and risk was significantly increased by being unmarried and both by not initiating prenatal care by end of first trimester and receiving no prenatal care. Preliminary samples were too small for solid inferences for other races. Anticipated results are that after propensity score match, earlier initiation of prenatal care will show modest protective effect on preterm birth, but other characteristics such as maternal cigarette smoking during pregnancy and DUI status will show stronger effects on predicting preterm birth risk. DISCUSSION/SIGNIFICANCE OF IMPACT: By evaluating the role of prenatal care initiation and delivery on preterm birth, this work provides an evidence base for prenatal care schedules and for understanding the interplay of sociodemographics, healthcare delivery, and individual characteristics in the context of preterm birth risk and potentially reduce negative health outcomes.

Objectives/Goals: In this project, we set out to supplement our existing grant writing workshops with targeted, learner-centered, multimodal training. This method will assist us in moving toward a more equitable training landscape, reaching a wider variety of learners, by freely disseminating these resources. Methods/Study Population: To increase access and impact of training materials for our career development grant writing workshops, we restructured our pre-workshop training videos. We culled expert advice from lengthy recorded lectures into brief (less than 5 minute) how-to videos that target instruction to writing specific sections of an NIH K grant. We then coupled these how-to videos with easy-to-navigate, open access online courses that further illustrate best practices for writing key sections of NIH K grants. These resources were given to registered workshop attendees and made available through a public Canvas course, the Diamond portal, MICHR website, and U-M Innovation Partnerships to disseminate the materials through multiple channels. Results/Anticipated Results: Four online courses and complementary videos were developed over six months, each focusing on a specific section of the NIH K grant proposal. These resources provide targeted instruction for writing the Specific Aims, Candidate Background, Career Development Plan, Career Goals and Objectives, and Mentor Letter. Learners accessed all four of the online courses. Released in January 2024, we continue to gather data on whether learners believe their knowledge about writing successful K grants has increased after using the resources, if they believe the courses have prepared them to write the section of the grant covered, and whether learners would recommend the courses. We will analyze these results to better understand how learners are using and responding to these new resources. Discussion/Significance of Impact: These how-to videos and online courses provide targeted, learner-centered training and fill an important gap by meeting learners where they are and extending the impact of our training beyond our institution. Widely disseminating online interactive training resources is a model we are applying beyond grant writing to other projects.

OBJECTIVES/SPECIFIC AIMS: The purpose of this study is to determine if the prevalence of interdisciplinary collaborations has increased over the past 10 years at 1 CTSA-funded institution. METHODS/STUDY POPULATION: We used Scopus to identify all articles published by authors affiliated with any of the Johns Hopkins Institutions for the years 2005, 2010, and 2015. We limited the search by the Scopus Field Codes “Subject Area” to biomedical science only, “Document Type” to articles only, and “Source Type” to journals only. We further eliminated all articles with 1 author or more than 10 authors. This resulted in 2800 articles for 2005, 3987 for 2010, and 4569 for 2015. After exporting the articles, we randomly selected 25 from each of the 3 time periods. Using the World Public Library Outline of Academic Disciplines as a guide, every author was assigned 1 of the following disciplines: Social Science (eg, Psychology), Basic Science (eg, Biology, Chemistry), Agriculture, Computer Science, Engineering, Medicine, Public Health, Nursing, or an Interdisciplinary field (eg, Genetic Medicine) based on their department and school affiliation. Articles with authors who belonged to 1 discipline only were considered single-discipline articles, and articles with authors in a least 2 different disciplines were considered “interdisciplinary.” RESULTS/ANTICIPATED RESULTS: Based on the results of an initial pilot study, in 2005, 24% of articles were interdisciplinary, in 2010, 20% of articles were interdisciplinary, and in 2015, 60% of articles were interdisciplinary. The large gap between the first 2 time periods (2005 and 2010) and the most recent (2015), suggests a possible pattern of increasing growth of interdisciplinary collaborations over time. Expanding this analysis to a much larger sample size will provide additional important evidence. DISCUSSION/SIGNIFICANCE OF IMPACT: Increasing emphasis is being placed on evaluating the effectiveness of the CTSA consortium in achieving its goals and on developing methods to gauge its success. Systematic methods that are easy to replicate across hubs are needed to better understand and track the evolution of scientific collaborations over time. This study outlines a process for determining whether one of the major desirable outcomes of the CTSA, notably the growth of interdisciplinary collaborations, can be determined through the analysis of authorship patterns. Further research is needed to confirm the generalizability of these results across other CTSA hubs.

Objectives/Goals: REDCap is a popular electronic data capture tool. However, training users in how to best utilize REDCap can be a challenge for many institutions. The Clinical and Translational Science Institute (CTSI) strives to setup a self-service training program that takes the day to day roles of users into account. Methods/Study Population: Our new training curriculum is a collaboration with our Workforce Development team and our REDCap Support Team. The REDCap team functions as the subject matter experts and generate a training outline based on a certain feature or topic. The Workforce Development team transform that outline into an LMS style course that’s available online. In order to organize the courses for maximum relevance to user, we engaged with various REDCap training and regulatory experts around the globe. Based on their input, we organized the various training courses into a role-based schema. The training courses are freely available online and contain an optional test and completion certification in order to comply with regulatory standards like 21 CRF part 11 or GDPR. Results/Anticipated Results: We released the first 17 training courses in July 2024 with another 20 courses planned in the near future. Responses to the courses have been overwhelmingly positive from users and the greater REDCap community. Our collection of training courses won the best website award at the yearly REDCap conference in 2024. To date we have had 137 people go through a training course with the optional test and completion certificate. While the majority have been from the USA, a significant portion hails from other countries. We believed these people only represent a small subset of users due to the optional nature of the test and accreditation section. Discussion/Significance of Impact: Our new role-based training curriculum is crucial in giving REDCap users the training tools they need for their particular role. The certification option fills a niche for professionals to demonstrate their REDCap proficiency to further their careers. Overall, this user training should increase the utilization of REDCap in all research endeavors.

OBJECTIVES/GOALS: Despite the large body of evidence concerning the effects of dietary interventions on blood pressure, trials have often reported poor adherence to sodium restriction. We implemented the Sodium Watcher Program-Hypertension (SWPH) program using digital self-monitoring. The purpose of this study was to determine the feasibility of the SWPH program. METHODS/STUDY POPULATION: The SWPH is a pilot two-arm, 2-month randomized controlled trial that enrolls adults with hypertension. The intervention group received personalized feedback on dietary sodium intake and BP and the control group participants received usual care for hypertension. Both groups participated in digital self-monitoring of daily diet and BP over 8 weeks. The primary outcomes were adherence to dietary sodium intake as captured by 24-hour urinary sodium excretion and BP at baseline and at the 2-month follow-up. Feasibility assessment included adherence to dietary sodium intake monitoring and in-home BP monitoring measured by the percentage of days that participant logged their food intake and in-home BP. The preliminary effect on the outcome variables was tested by using a repeated-measures analysis of variance. RESULTS/ANTICIPATED RESULTS: In this feasibility study, we included data from 12 participants (n=9 SWPH, n=3 control) who completed all phases of the study. The patients median age was 56.5 years and 70% were female. The mean baseline BP was 142.7/87.5 mmHg. The mean 24-hour urine sodium of 4853.0 mg (SD=1639.9 mg) with 80% having 24-hour urine sodium >2300 mg at baseline. SWPH group had lower systolic (baseline 142.4 mmHg vs follow-up 124.1 mmHg, p<0.001), diastolic (baseline 87.1 mmHg vs follow-up 77.5 mmHg, p<0.05) BP, and 24-hour urine sodium (baseline 3790.4 mg vs 2609.7 mg, p<0.05) compared with control group. Compared with the control group, the SWPH group had significantly more eligible days of digital food log usage (control 80.0% vs intervention 98.2%, p<0.01) and in-home BP monitor usage (control 77.6% vs intervention 94.6%, p<0.01). DISCUSSION/SIGNIFICANCE: Millions of Americans remain in need of effective interventions to manage their hypertension. Innovative and accessible strategies to sustain a low sodium diet intervention are needed for the majority of individuals not following the low sodium diet. By leveraging digital self-monitoring, a low sodium diet program was feasible and in reducing BP.

OBJECTIVES/SPECIFIC AIMS: To respond to the need for a simple tool to answer individual researchers questions: Exactly what training do I need to complete for my study and my role? Where can we go to find a comprehensive record of my research training? METHODS/STUDY POPULATION: Identify the factors that determine what training is required for each role (i.e., PI, coordinator, biostatistician) at the University, their role on the research study, type of funding, population being studied and responsibilities/duties on the research team. Develop an inventory of training required according to federal and local regulations and guidelines. Identify other related factors that ensure ongoing compliance for research professionals (i.e., medical licenses, CVs, immunizations, and credentials). Collaborate with programming professionals to explore and confirm the feasibility of such a Web site. Incorporate formal usability and pilot testing as part of the programming design process. Develop User Guide and Marketing and Launch plan for users and supervisors. Implement phased launch of the site with Google analytics, and evaluate the experience of phase I users. RESULTS/ANTICIPATED RESULTS: Three months user data and evaluation results demonstrated: 149 users created Training Roadmaps on the site. Users were from 67 different department codes, with the Department of Psychiatry the primary user. 20 users responded to a survey three months after launch. Research coordinators were the primary focus for phase I and represented almost half of the users. Survey respondents rated the site ease of use and clarity of the site as its greatest benefit. DISCUSSION/SIGNIFICANCE OF IMPACT: In September 2017, CTSI launched a new web-based training tool exclusively for University of Minnesota clinical research professionals who work with human participants, and their supervisors. The Human Research Training Web site is a free, easy-to-use tool to help identify and maintain the appropriate training, certification, credentials, and immunizations needed to perform University of Minnesota research with human participants. The Web site offers the University’s first systematic way to identify which research training is necessary for each research professional, and a system to track and maintain training compliance. Training records and information from the University of Minnesota’s central databases are securely integrated into this tool. Our Web site tool enhances research compliance. Any given study team member’s training requirements vary based on several criteria such as: role at the University, role on the research study, type of funding, population being studied and responsibilities/duties on the research study. The research training Web site generates required and optional training based on individuals’ responses to these questions. This Web site also links to the training, which decreases error in taking the wrong training. Furthermore, it provides completion data for research training and is a repository for vital study information such as: medical licenses, CVs, and credentials. Supervisors are able to view training and credentials. They are alerted when one of their employee’s licenses or certificates are about to expire. Uses-to-date and evaluation feedback have informed the need for a second phase of Web site enhancements. This site will reside in both the CTSI Web site and the HRPP Web site. A link will be sent to all new University research employees upon hiring. The Human Research Training Web site will likely have applicability to other universities in addition to the University of Minnesota.

ABSTRACT IMPACT: Findings from this study have the potential to improve interventions geared toward YBW, by highlighting the potential for technology-based HIV interventions. OBJECTIVES/GOALS: A stark disparity in HIV exists for Black American women, with 61% of all new HIV infections among American women occurring in Black women. Using technology to address community-level HIV risk may be beneficial, however few studies have examined the association of tech-based communication and HIV prevention behaviors among Black women. METHODS/STUDY POPULATION: Egocentric social network data from 201 young Black women (YBW) were collected from June 2018 to December 2018 to identify how social media use (e.g., amount of time, type of social media used, health information seeking) and sexual health communication (e.g., talk about condom use via face-to-face, text or phone and talk about HIV testing via face-to-face, text or phone) were associated with condom use, HIV testing and interest in pre-exposure prophylactic (PrEP). Statistical analysis proceeded in two stages, descriptive statistics and multivariate logistic regression modeling. RESULTS/ANTICIPATED RESULTS: Instagram (82%) and Snapchat (79%) were the most used social media platforms for communication with SNMs. About 20% of YBW reported spent 4 or more hours on social media per day, and a majority of YBW spoke to at least one SNM via text (85%), face-to-face (98%), or on the phone (97%). Multivariate logistic regression results indicated that YBW who spoke to their SNMs via Instagram had 3.23 times the odds of using condom during last sex, however if they spoke to SNMs on twitter or spent more then 4 hours on social media they had a decrease in odds of using condoms. YBW had 96% decreased odds of ever being tested for HIV if they spoke to a SNM face-to-face about condom use; and notably, YBW had 3 times the increased odds in interest of using PrEP if they had sex with someone they met online or if they sought sexual health information online. DISCUSSION/SIGNIFICANCE OF FINDINGS: By assessing the modes of communication YBW are using to speak with their SNMs and their associations with HIV prevention behaviors, we can better determine the most optimal, efficient, and effective ways of utilizing technology for HIV intervention.

Objectives/Goals: This proposal outlines the successful deployment of a research training initiative to support the formation of a Learning Healthcare System. Mayo Clinic Health System (MCHS) rural providers were offered the opportunity to the fundamentals of clinical research via Clinical and Translational Science Awards core curriculum, mentorship, and an online seminar series. Methods/Study Population: MCHS funded 4 key introductory research courses: 1) Manuscript Writing, 2) Grant Writing, 3) Basic Biostatistics, and 4) Essentials of Clinical and Translations Science Program. In addition to course offerings, a Research Interest Group was formed to guide novice rural researchers on topic selection and study design. This cultivated interest to create a 16-month clinical research webinar series offering CME credits. Subsequently, an internal MCHS RFA was launched seeking early-stage investigator pilot proposals focused on rural health. Results/Anticipated Results: In 2023, over 140 MCHS providers enrolled in 324 CCaTS research courses. This training led to the submission of 53 proposals to the inaugural MCHS 2023 RFA, of which 15 were awarded. Additionally, 14 MCHS extramural grants were submitted in 2023. Training efforts expanded in 2024 to include an online research seminar series covering various study topics and providing CME credit, with an approximate attendance up to 196 attendees per session. The second annual MCHS RFA resulted in 4 internal awards, with an additional 22 extramural grant submissions. These collective efforts have increased the number of MCHS first and last author publications and the number of MCHS providers with academic rank. Discussion/Significance of Impact: Leadership’s commitment of resources to educate, mentor, and engage clinicians was crucial to our success and demonstrated a strong return on investment. To maximize impact in community-based practice, continued commitment is needed in the form of protected research time, funding, and research administration support of projects of interest

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.

OBJECTIVES/GOALS: Describe the community of Norther Dauphin County, PA and increase awareness of this community’s health related needs. Establish partnerships between Penn State faculty and Northern Dauphin County community-based organizations to develop an optimal approach to address identified health related needs. METHODS/STUDY POPULATION: Northern Dauphin is located in the rural Northern Tier of Dauphin County, PA and has roughly 30,000 residents within 272 square miles. Of those residents, approximately 1 in 4 families live below the poverty level. Although over 6,000 residents receive Medical Assistance (MA), only one local provider accepts MA covered patients. Residents have limited access to health care due to the rurality of the area when paired with a lack of public transportation. The Penn State Clinical and Translational Science Institute (CTSI) Community Engaged Research Core (CERC) has partnered with Northern Dauphin County community- based organizations to explore the needs of community members and how partnerships with Penn State Faculty could help to address the community needs. RESULTS/ANTICIPATED RESULTS: A Community Advisory Board (CAB) of leaders (e.g., school officials, business owners) was created to identify community needs. After an initial workshop with the CAB, an assessment was created and distributed to the larger community to identify the top community health needs. Details from the assessment were then used to prioritize the themes for the Community Driven Research Day (CDRD). The CERC team identified Penn State University faculty with research interests related to these prioritized themes. The faculty identified and community leaders were then invited to the CDRD. The agenda for the event included an introduction to Community Engaged Research, a presentation from a researcher and community partner working together, round table discussions based on the themes selected, and an overview of pilot grants. DISCUSSION/SIGNIFICANCE: The CDRD will facilitate partnerships between the Penn State faculty and local community leaders to help effectively move forward addressing the community’s health needs. The PSU CTSI will offer pilot grants to formalize and strengthen these partnerships and conduct community engaged research initiatives to discover optimal ways to address them.

OBJECTIVES/SPECIFIC AIMS: The goal of this innovative course is to provide community members with sufficient information to either join or decline participation in clinical research. We anticipate that they will gain knowledge in why research is conducted, the ways participants are recruited, the history of research, regulations that guide research today, participant protections, understand the consent process, their risks and benefits of participating in clinical research. METHODS/STUDY POPULATION: We will recruit interested community members via flyers placed at the training location and at other local community centers and agencies that receive heavy foot traffic. The course is listed in the Communiversity catalogue which is distributed in hardcopy (over 30,000) and email each semester. The course will be taught by a longstanding community member and research coordinator at the University of Cincinnati. Each session will be highly interactive including videos, role-play, and discussion of the presented research topics. Evaluation will occur both pre and post-session, along with pre and post-course. RESULTS/ANTICIPATED RESULTS: We anticipate 20–30 participants at each of the 4 sessions. We anticipate that we will learn current perceptions of clinical research and barriers to their participation to enable improved research recruitment. In addition, we will gain new insights into clinical research needs of the community. DISCUSSION/SIGNIFICANCE OF IMPACT: Through these interactive sessions, we will learn why community members participate in research and their barriers to participating. Understanding the perception of research by the target community is critical when developing clinical research recruitment strategies. We will also be developing a more educated community towards clinical research. We will also gain great insight into new clinical research directions as indicated by community members.

Access to an academic clinical research center (CRC) in health professional shortage areas (HPSA) can help address healthcare disparities and increase research accessibility and enrollment. Here we describe the development of a community-centered CRC in the underserved area of Sunset Park, Brooklyn, New York, centered within a larger academic health network and the evaluation of its outcomes within the first two years. In addition to resources and space, establishment of the CRC required a culturally competent and multilingual team of healthcare professionals and researchers and buy-in from the community. Between 1/2022 and 12/2023, the CRC opened 21 new trials (10 interventional and 11 noninterventional) with greater than 500 participant visits that reflect the racial and ethnic diversity of the community. These participants represent 110 distinct zip codes; 76% of these zip codes are underserved and designated HPSA. 60% self-identified as non-White and 20% identified as Hispanic, with 12 other distinct ethnicities represented. 28% of participants speak 11 languages other than English. Community-based CRCs can be created with sustainable growth to align with the mission of the National Institutes of Health and U.S. Food and Drug Administration to meet the ever-growing clinical, social, and research needs of the communities they serve.
