4298 Prediction models for pulmonary tuberculosis treatment outcomes: a systematic review
Authors: Peetluk Lauren Saag , Ridolfi Felipe , Rolla Valeria , Sterling Timothy
Published: July 2020

OBJECTIVES/GOALS: Many clinical prediction models have been developed to guide tuberculosis (TB) treatment, but their results and methods have not been formally evaluated. We aimed to identify and synthesize existing models for predicting TB treatment outcomes, including bias and applicability assessment. METHODS/STUDY POPULATION: Our review will adhere to methods that developed specifically for systematic reviews of prediction model studies. We will search PubMed, Embase, Web of Science, and Google Scholar (first 200 citations) to identify studies that internally and/or externally validate a model for TB treatment outcomes (defined as one or multiple of cure, treatment completion, death, treatment failure, relapse, default, and lost to follow-up). Study screening, data extraction, and bias assessment will be conducted independently by two reviewers with a third party to resolve discrepancies. Study quality will be assessed using the Prediction model Risk Of Bias Assessment Tool (PROBAST). RESULTS/ANTICIPATED RESULTS: Our search strategy yielded 6,242 articles in PubMed, 10,585 in Embase, 10,511 in Web of Science, and 200 from Google Scholar, totaling 27,538 articles. After de-duplication, 14,029 articles remain. After screening titles, abstracts, and full-text, we will extract data from relevant studies, including publication details, study characteristics, methods, and results. Data will be summarized with narrative review and in detailed tables with descriptive statistics. We anticipate finding disparate outcome definitions, contrasting predictors across models, and high risk of bias in methods. Meta-analysis of performance measures for model validation studies will be performed if possible. DISCUSSION/SIGNIFICANCE OF IMPACT: TB outcome prediction models are important but existing ones have not been rigorously evaluated. This systematic review will synthesize TB outcome prediction models and serve as guidance to future studies that aim to use or develop TB outcome prediction models.

Published: July 2020

OBJECTIVES/GOALS: African-Americans have a 3-fold higher risk of end-stage kidney disease (ESKD) compared to Whites due in part to APOL1 risk alleles. Whether resistant hypertension (RH) magnifies the risk of ESKD among African Americans beyond APOL1 is not known. We examined the interaction between RH and race on ESKD risk and the independent effect of RH beyond APOL1. METHODS/STUDY POPULATION: We designed a retrospective cohort of 240,038 veterans with HTN, enrolled in the Million Veteran Program with an estimated glomerular filtration rate (eGFR) >30 ml/min/1.73m2. The primary exposure was incident RH (time-varying). The primary outcome was incident ESKD during a 13.5 year follow up: 2004-2017. Secondary outcomes were myocardial infarction (MI), stroke, and death. Incident RH was defined as failure to achieve outpatient blood pressure (BP) <140/90 mmHg with 3 antihypertensive drugs, including a thiazide, or use of 4 or more drugs. Poisson models were used to estimate incidence rates and test additive interaction with race and APOL1 genotype. Multivariable Cox models (with Fine-Gray competing-risks models as sensitivity analyses) were used to examine independent effects. RESULTS/ANTICIPATED RESULTS: The cohort comprised 235,046 veterans; median age was 60 years; 21% were African-American and 6% were women, with 23,010 incident RH cases observed over a median follow-up time of 10.2 years [interquartile range, 5.6-12.6]. Patients with RH had higher incidence rates [per 1000 person-years] of ESKD (4.5 vs. 1.3), myocardial infarction (6.5 vs. 3.0), stroke (16.4 vs. 7.6) and death (12.0 vs. 6.9) than non-resistant hypertension (NRH). African-Americans with RH had a 2.6-fold higher risk of ESKD compared to African-Americans with NRH; 3-fold the risk of Whites with RH, and 9.6-fold the risk of Whites with NRH [p-interaction<.001]. Among African-Americans, RH was associated with a 2.2-fold (95%CI, 1.86-2.58) higher risk of incident ESKD in models adjusted for APOL1 genotype and in the subset of African-Americans with no APOL1 risk alleles, RH was associated with an adjusted 2.75-fold (95% CI: 2.00-3.50) higher risk of incident ESKD. DISCUSSION/SIGNIFICANCE OF IMPACT: RH was independently associated with a higher risk of ESKD and cardiovascular outcomes, especially among African-Americans. This elevated risk is independent of APOL1 genotype. Interventions that achieve BP targets among patients with RH could curtail the incidence of ESKD and cardiovascular outcomes in this high-risk population. CONFLICT OF INTEREST DESCRIPTION: None.
4155 THE ROLE OF PERIODONTAL DISEASE IN CORONARY ARTERY DISEASE IN A HISPANIC POPULATION
Authors: Altieri Pablo I , Didriksen Kiara , Altieri Pablo , Banchs Hector L. , Escobales Nelson
Published: July 2020

OBJECTIVES/GOALS: The purpose of this report is to describe the role of Periodontal Disease (PD) in Coronary Artery Disease (CAD) in a Hispanic country. METHODS/STUDY POPULATION: Literature and Puerto Rican experience was reviewed and will be discussed. RESULTS/ANTICIPATED RESULTS: PD produces inflammatory disease by bacterial infection in the gingiva. This factor PD activates an inflammatory process affecting the CAD cascade inducing myocites, endothelial cells activation and cytokines. The incidence of gingival disease in the Puerto Rican population (P) is around 50%; of this group 80% will develop periodontal disease. Including this factor and diabetes mellitus Type 2, still the incidence of CAD is 20-30% less than the U.S.A. DISCUSSION/SIGNIFICANCE OF IMPACT : CAD is a systemic disease related to genetic factors and inflammation. PD is related to an inflammatory process, which will activate the CAD process, producing tissue infarcts. The daily use of resolving or liquid Omega 3 in the gingival tissue is useful in the prevention of gingival and periodontal disease. CONFLICT OF INTEREST DESCRIPTION: All authors have no relationship with any industry or financial associations in connection with the submitted abstract.
4294 Patient Matching Errors and Associated Safety Events
Authors: Greer Melody Lynn
Published: July 2020

OBJECTIVES/GOALS: Errors in patient matching could result in serious adverse safety events. Unlike publicized mix-ups by healthcare providers these errors are insidious and with increased data sharing, this is a growing concern in healthcare. The following project will examine patient matching errors and quantify their association with safety. METHODS/STUDY POPULATION: EHR systems perform matching out-of-the-box with unknown quality. Using matching processes outside the EMR, the rate at which matching errors are present was quantified and the erroneous records were flagged providing both comparative measures and data necessary to evaluate patient safety. To understand the relationship between matching and safety we will establish a percent of voluntarily reported safety events in our institution where a matching error existed during an encounter. Any safety events occurring for a flagged patient will be reviewed to determine if matching errors contributed to the safety problem. Not all safety events are reported so we will perform full chart review of a filtered list of medical records that have a higher likelihood of safety events. RESULTS/ANTICIPATED RESULTS: We were able to quantify matching errors, and the preliminary matching error rate is approximately 1%, representing over 700 patients. The work is in progress and we are beginning to determine the association between safety events and incorrect matching. Together these results will provide an incentive to identify errors, make corrections, and develop methods to achieve these objectives. The number of matching errors impacts patient care as well as business operations and is likely to have a negative financial impact on institutions with high error rates regardless of its relationship to safety. DISCUSSION/SIGNIFICANCE OF IMPACT: Patient matching is bundled with EHR software and institutions have little control over error rates, yet bear the liability for resulting clinical error. Institutions need to be able to identify undetected matching errors and any associated safety events and this project will provide that solution.
4386 Age-related Changes in the Functional Connectivity within the Default Mode Network
Authors: Leonardo Cassandra , Franklin Crystal G , Fox Peter T
Published: July 2020

OBJECTIVES/GOALS: To evaluate whether the default mode network experiences age-related changes in functional connectivity and to identify these patterns of progression across seven decades of life. The overall goal is to evaluate whether quantifying these functional changes can serve as potential neurobiomarkers of aging for further quantitative genetic analyses. METHODS/STUDY POPULATION: Scans were performed at the RII on a 3T Siemens Trio scanner with an 8-channel head coil. Whole-brain, rsfMR imaging was performed using a gradient-echo EPI sequence sensitive to the BOLD effect (TE/TR = 30/3000 ms; flip angle = 90°; isotropic 1.72 mm2). Subjects were instructed to lie in dimmed light with their eyes open and try not to fall asleep. Image analysis was performed with FMRIB’s Software Library tools (www.fmrib.ox.ac.uk/fsl). Preprocessing of resting state data includes motion correction, brain extraction, spatial smoothing, and high-pass temporal filtering. Time series data was extracted from 9 DMN ROIs using FSL’s Featquery tool with 6mm radius spherical ROI masks created in Mango. After extraction, DMN connectivity was assess using structural equation modeling implemented in Amos 22.0 (IBM, Inc.). RESULTS/ANTICIPATED RESULTS: The exploratory SEM (eSEM) default mode network (DMN) model used consists of 9 regions of interest and 13 functional connectivity paths. The eSEM DMN model exhibited exceptional model fit to a primary resting state data set of 1169 subjects from the Genetics of Brain Structure project (1R01MH078111-01, David Glahn PI) with an RMSEA of 0.037. This model also had excellent model fit in 7 cohorts that were grouped by decade age (10s – RMSEA: 0.058, 20s – 0.051, 30s – 0.045, 40s – 0.048, 50s – 0.043, 60s – 0.035, 70s – 0.037). Analysis of the decade group-wise path coefficients identified 7 of the 13 paths (pC -> LMTG, pC -> PCC, PCC -> MPFG, PCC -> vACC, MPFG -> vACC, LIPL -> RIPL, LMTG -> RMTG) significantly negatively correlated with age-related changes. As early as the 1st decade of life, the functional connectivity within the DMN decreases. DISCUSSION/SIGNIFICANCE OF IMPACT: The DMN experiences progressive age-related decreases in connectivity, beginning in the first decade of life. Our results suggest that DMN path coefficients can serve as biomarkers of cognitive aging, which can then be used as quantitative traits for genetic analyses to identify genes associated with normal aging and age-related cognitive diseases.
4192 Decreasing Inappropriate STAT Image Ordering
Authors: Cui Michael , Chung Jonathan , Patel Pritesh , Reiser Ingrid
Published: July 2020

OBJECTIVES/GOALS: Currently physicians are able to order CT Chest/Abd/Pelvis images as STAT or Routine. STAT images denote an emergency and are done immediately. We aim to determine the percentage of CT images that are inappropriately ordered as STAT, determine physician image ordering habits, and develop targeted interventions to encourage appropriate STAT image ordering. METHODS/STUDY POPULATION: A fishbone diagram helped reveal possible causes of inappropriate STAT image ordering. Based on the fishbone diagram, a survey was created to assess CT image ordering habits amongst radiology and internal medicine residents and attending physicians. All CT Chest/Abd/Pelvis images ordered over a 3 month period of time (July-Oct 2017) was obtained. The dataset included whether the image was ordered Stat vs Routine, time of image order, physician name and location, and reason for the imaging study.The STAT images were evaluated based on the explanation provided in the CT image order. Currently 2 radiology residents, 2 internal medicine residents, and 2 internal medicine hospitalists are evaluating all STAT CT images to determine appropriateness and how long they are willing to wait for the image to result in a read. RESULTS/ANTICIPATED RESULTS: Analysis of all CT Chest/Abd/Pelvis imaging orders revealed that 51% (1710/3345) of them were ordered as STAT. The preliminary analysis of 227 STAT images showed that 6% were inappropriate. We anticipate results of our survey to show differences in how long a STAT vs Routine image orders should take amongst Radiology and Internal Medicine clinicians. We also anticipate our survey to show differences in factors that warrant STAT imaging amongst the different medical fields. We anticipate that the clinician manual evaluation of all STAT CT image will reveal a large percentage of imaging orders to be inappropriate. All STAT imaging that were flagged as inappropriate will be characterized by the department who ordered the image and the reason provided for the imaging to assess for common themes. DISCUSSION/SIGNIFICANCE OF IMPACT: STAT images are the new routine with more images ordered STAT than Routine. Inappropriate STAT imaging results in truly urgent patients not getting the medical care they need. Many images ordered stat could potentially be switched to routine. By evaluating why clinicians are ordering STAT CT image inappropriately, we will be able to develop targeted interventions to decrease inappropriate STAT CT imaging.
4056 Dementia family caregivers’ mobile app use and intention to adopt mHealth apps
Authors: Mendez Kyra Jennifer Waligora , Ra Han Hae
Published: July 2020

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.
4195 “Learning Shots” are an Innovative, Versatile Educational Tool for Clinical and Translational Science
Authors: Eby Jean , Hoffman Susie , Johnston Karen , Phillips Jennifer
Published: July 2020

OBJECTIVES/GOALS: To demonstrate how brief online audiovisual presentations, “learning shots”, informed by evaluation, can be used to quickly and effectively provide essential just-in-time research-related education in the complex and evolving world of clinical and translational science. METHODS/STUDY POPULATION: “Learning shots” are an educational tool, originally developed by the University of Virginia IRB for Health Sciences Research, that cover a broad spectrum of methodological, regulatory, and ethical topics in research. They are designed to be responsive to adult learners, a rapidly changing research environment, and the need for flexible offerings. Learning shots target different groups involved in research including clinical research coordinators, investigators, and trainees. A survey was used to assess the role of learning shots in meeting learning needs. Moving forward, continuous evaluation will occur through the addition of tracking and a short evaluation survey to each learning shot. RESULTS/ANTICIPATED RESULTS: The University of Virginia has an online library of over 30 learning shots. Learning shots are used to cover foundational topics (e.g. GCP) as well as more specialized topics (e.g. comparative effectiveness research). They can also be used to quickly respond to breaking issues (e.g. single IRB review). In an initial survey targeting University of Virginia clinical research coordinators, 54 (68%) of 79 respondents reported having viewed a learning shot. Among those who had, 41 (84%) of 49 respondents reported that learning shots were helpful to their learning needs. Continuous evaluation is expected to further inform how learning shots meet clinical and translational science education needs. DISCUSSION/SIGNIFICANCE OF IMPACT: Learning shots are an innovative and versatile educational tool for clinical and translational science that can be used to quickly and effectively convey important research information in response to an increasingly complex research environment and diverse learner needs.

Published: July 2020

OBJECTIVES/GOALS:

Develop strong network of science teachers interested in promoting scientific research to their students.

Place students in an immersive summer research internship that, when possible, matches their career interests.

Expose students to the numerous career paths within the STEM field.

METHODS/STUDY POPULATION:

The program recruits socio-economically disadvantaged students and provides them a stipend, and also accepts students who can participate unpaid.

Local school teachers are engaged in a summer fellowship to learn biotechnologies and research. In Spring these teachers help recruit students and during the subsequent Fall help students with college and scholarship applications.

Students are placed in a variety of laboratories within the Schools of Medicine, Science, Dentistry, Public Health, Informatics, Health and Human Sciences, Engineering and Technology, especially in biomedical engineering. Students are also placed in industry laboratories such as Eli Lilly and the Indiana Bioscience Research Institute.

Long-term program follow-up is done through post-internship surveys to assess impact on graduate and professional school admission.

RESULTS/ANTICIPATED RESULTS:

Since the Indiana CTSI was established in 2008, 872 students have participated in the summer internship.

71% of past interns are underrepresented minorities in science or classified as disadvantaged by NIH criteria.

17% of students interned during grade 10, 72% during grade 11, and 11% during grade 12.

21% of students engage in the program for more than one year.

100% of past interns are currently enrolled in or have graduated college.

Over 60% of those with a bachelors degree proceed to graduate and professional schools and over 80% stay in STEM related fields. These rates are equal for interns from underrepresented minorities or those classified as disadvantaged by NIH criteria.

DISCUSSION/SIGNIFICANCE OF IMPACT:

Students engaged in the Indiana CTSI STEM program are progressing through the translational science pipeline based on their graduating from college and remaining in the STEM field.
4207 Development and Evaluation of a Pilot Mentor Training Program for Clinical Translational Research Professional Workforce
Authors: Strekalova Yulia A. , Kolb H. Robert , Morris Holly , Austin-Datta Rebecca
Published: July 2020

OBJECTIVES/GOALS: The goal of this project was to develop and evaluate a pilot mentor training program for clinical research professionals. This project presents an evidence- and theory-based mentoring program that has been developed, implemented, and evaluated for this group of translational research professions. METHODS/STUDY POPULATION: The curriculum for the program was designed for aspiring mentors and aligned with the topics of existing Entering Mentoring curriculum for translational workforce (Pfund, Branchaw & Handelsman, 2015). Eleven experienced CRPs participated in the pilot training program. The training was delivered in two-hour meetings over eight weeks. Qualitative e-mail interviews and a validated mentoring competency assessment (Fleming et al., 2013) and mentor role assessment (Dilmore, 2010) tool were used for process and outcome evaluation. Cases studies specific to the CRPs work environment were developed and used to facilitate discussions throughout the training. RESULTS/ANTICIPATED RESULTS: Pre- and post-training scores for mentoring competency assessment were compared across six sub-indexes. Paired t-tests showed a significant difference for the maintaining effective communication competency, p = 0.0202. Comparisons of individual items also showed positive changes in the promoting professional development competency, p = 0.0161). Qualitative assessment revealed that most mentor trainees recognized a distinction between a mentor and a supervisor or on-the-job-trainer. Furthermore, most have been informal mentors without a formal role assignment, the need for ongoing mentoring, and potential of mentoring networks. DISCUSSION/SIGNIFICANCE OF IMPACT: CRPs is a diverse group of research support professionals who may hold the roles of research study coordinators, research nurses, regulatory and compliance specialists. Tailored mentoring can provide essential infrastructure for ongoing professional development and support talent retention.
4160 Evaluating Student Team Dynamics
Authors: Chao Celia , Tumilty Emma , Chao Celia , Aronson Judith , Hommel Jonathan D. , Hellmich Mark R.
Published: July 2020

OBJECTIVES/GOALS: We aimed to explore the students’ assessments of workload distribution by comparing personal reflective commentaries and team documents defining division of labor in a team science setting. METHODS/STUDY POPULATION: The Interprofessional Research Design course models the team science experience by bringing together MD and PhD students to write a research grant. Four teams of 13 students were tasked with both individual and team-based assignments: 1) Each week, each student reported their perception of their own and their team members’ effort over the week (totalling 100%). 2) Iterative work contracts for each team were submitted at four time-points; assigned work toward project completion totalled 100%. 3) Lastly, each student submitted a short commentary reflecting on the prior week’s team dynamics and teamwork. We retrospectively performed a mixed-methods analysis of the workload data. RESULTS/ANTICIPATED RESULTS: Group-reporting in the team contracts remained static throughout the course, often stating equal distribution of workload, whereas individual reporting was more dynamic. Of 13 students, 8 rated more than 50% of the weeks as balanced. Among some students, there was a discordance of workload distribution when comparing the group document to the individual perceptions of work performed by their teammates. Reflective writing mapped more closely to individual quantitative reports. The data also revealed within team variations, where one student may report a higher proportion of their contributions, while the rest of the team attributed that student a lower percentage of the total work. DISCUSSION/SIGNIFICANCE OF IMPACT: An important aspect of team function is workload distribution. Group-based workload discussions may be a useful framework, but does not provide insight into team dynamics, whereas individually reported workload distributions and short reflections seem to more accurately inform us on team function.

Authors: Greenberg-Worisek Alexandra Joelle , Cornelius Katherine , Gas Becca , Silvano Carmen , Weavers Karen Marie , Roberts Lewis R , Ekker Stephen C , Enders Felicity , Windebank Anthony
Published: July 2020

OBJECTIVES/GOALS: The Mayo Clinic Clinical and Translational Science (CTS) Predoctoral program aims to develop independent researchers capable of leading multi-disciplinary teams to accelerate the translation of discovery to application. Here, we detail the outcomes of our graduates over the past ten years (2010-2019). METHODS/STUDY POPULATION:): A survey was fielded with all CTS graduates whose degrees were conferred since the program’s inception to 2019. Items addressed their current position, whether they were still involved in research, what type of research they were involved in, and whether they stayed involved with education. They also submitted a recent CV, from which data were collected about publications and grants. A subset were then contacted for a semi-structured interview. Items included questions addressing motivation for pursuing a PhD in CTS, whether the program prepared them for their current work, gaps they felt they had in training, and whether they felt they were making a difference in the lives of patients. RESULTS/ANTICIPATED RESULTS: Of the 41 alumni, 34 responded (83% response rate). Of these, 19 (56%) are at Mayo Clinic, 9 (26%) work for other academic institutions, and 6 (21%) do not work for an academic institution. Most have remained in research (33/34, 97%). The majority (22/33, 67%) are involved in clinical research, 30% (10/33) in basic science, and 24% (8/33) in healthcare delivery research. Most (23/34, 68%) are engaged in educational activities. When asked about changes they have led, 67% (18/27) led quality improvement projects and 44% (12/27) designed a new research method. Several hold leadership positions either in their organization (12/16, 75%) or in a professional organization (10/16, 63%). DISCUSSION/SIGNIFICANCE OF IMPACT: The CTS Predoctoral program successfully prepares scholars for careers involving clinical and translational research; furthermore, alumni remain in research-oriented careers after graduation. We will continue to gather longitudinal data alumni move forward in their careers.

Authors: Vitale Alfred , Lackey Russell , Trayhan Melissa , White Robert
Published: July 2020

OBJECTIVES/GOALS: The new CLIC Education & Career Development Gateway aims to be a translational science workforce ecosystem for CTSAs to share learning and training resources and career opportunities. The Gateway also provides individualized assistance to identify and implement TS learning and training resources. METHODS/STUDY POPULATION: The CLIC Education & Career Development Gateway, located on the CLIC website, is an entry way to: 1) the Education Clearinghouse, a platform where CTSA Program hubs can find and share educational resources individually or as part of resource kits; 2) the Opportunities Board, which includes jobs and mini-sabbaticals from CTSA Program hubs; and 3) the Education & Training Navigator, a personalized approach to education and training requests. These approaches help empower and support a cooperative learning and training community that is inclusive and collaborative, facilitating and amplifying opportunities for the sharing of educational resources throughout the translational science workforce. RESULTS/ANTICIPATED RESULTS: Through a person-centered, direct engagement approach, the anticipated outcomes of these efforts are to promote increased collaboration across CTSA Program Hubs and partners, and the amplification of accessible, relevant existing resources. Another anticipated outcome is increased production of educational materials through the reduction of work duplication and identification of gaps in education and training resources. The Gateway also provides an opportunity to communicate the work and efforts that consortium-level special groups (working groups, special interest groups, etc.) produce. Ongoing evaluations and suggestions will help determine future improvements and functionalities. DISCUSSION/SIGNIFICANCE OF IMPACT: CLIC’s education and training ecosystem promotes education as a community space to facilitate opportunities for collaboration and partnerships, amplifying visibility of the work created by members of the CTSA community, and encouraging a transformative career trajectory for trainees and scholars.
4515 The Impact of First Level Training Cycles (FLTCs) on Clinical and Translational Research (CTR) in knowledge and interest in CTR of students (S) and faculty (F) from health professions and basic science programs island wide in Puerto Rico (PR)
Authors: Santiago Juan Carlos Soto , Santiago Edgardo L. Rosado , Flores-Rivera Efraín , De Jesus-Ojeda Lizbelle , Irizarry-Ramírez Margarita , Alvarez Jose Rafael Moscoso , García Rubén
Published: July 2020

OBJECTIVES/GOALS: To assess the impact of FLTCs on CTR on S and F from health professions and basic science academic programs island wide in Puerto Rico. Cycles supported by the Title V Cooperative Project at University of Puerto Rico-Medical Sciences Campus (UPRMSC) and Universidad Central del Caribe (UCC)(Title V). METHODS/STUDY POPULATION: After offering FLTCs in CTR to S and F from UPRMSC and UCC, Title V expanded it to S and F from other institutions island wide in PR. These FLTCs were offered the 2nd semester of 2018 and consisted of 20 hours of interdisciplinary sessions in: introduction to and definition of CTR; preparation of a CTR-presentation; how to interview/share a presentation of a CT researcher and to prepare a research question in CTR. To assess the knowledge of S and F in the above-mentioned skills and their continuation in the 2nd level of CTR training, surveys were administered: pre-test, at the beginning, post-test, sometime during the FLTCs, and satisfaction at the end of the FLTCs. RESULTS/ANTICIPATED RESULTS: Fifty eight (58) S/F from UPRMSC, UCC and 7 other institutions participated. Forty two (42,72%) answered a pre-test and 31/42 (74%) completed the post-test. Results showed that S/F: who correctly defined CTR increased from 7% to 77 %; their ability to identify a CT researcher increased from 10% to 83%. Fifty five percent (55 %) (21/38) S/F that were certified in the FLTCs, answered the satisfaction survey. One hundred percent (100%) indicated that the materials offered contributed in the identification of a CT researcher and a topic in CTR; 100% answered that the FLTCs contributed higher knowledge in and provided new skills in CTR. Moreover, 31/38 (82%) S/F started the 2nd level of training. DISCUSSION/SIGNIFICANCE OF IMPACT: The FLTCs were successful in increasing S/F knowledge of CTR and to further engage in 2nd level of trainings. Title V impact extended island wide, increasing the diversity of represented health professions and science fields among participants. The interventions were deemed to be of high quality.
4274 Thirteen Years of Pipeline Programming at the University of Rochester’s Clinical & Translational Science Institute to Train Physician-Scientists
Authors: Maiorano Alaina , van Wijngaarden Edwin , Vitale Alfred , De Ver Dye Timothy , Gross Robert , O’Banion Kerry
Published: July 2020

OBJECTIVES/GOALS: Physician-scientists play a vital role in biomedical research but this chosen career path has many challenges, such as long training periods and funding. The University of Rochester (UR) CTSI pipeline programs address this by enabling medical trainees to partake in enriched research experiences. METHODS/STUDY POPULATION: The UR CTSI TL1 is a training grant from the National Center for Advancing Translational Science (NCATS), which funds predoctoral trainees. The TL1-funded physician-scientist pipeline includes the Academic Research Track (ART) year-out program and the Medical Science Training Program (MSTP). We describe the characteristics and training outcomes of TL1-funded trainees. We also obtained testimonials of current and former trainees regarding their career component decision-making, and their perception of programs, in order to identify how best to address the challenges of the physician-scientist workforce, and to facilitate the transition between the clinic and bench. RESULTS/ANTICIPATED RESULTS: From 2006-2019, the UR CTSI has had 56 ART trainees and 17 MSTP trainees complete training; six trainees have transitioned into the MSTP after completing the ART program. As of 2019, 63 of 67 graduated trainees (94%) have continued their engagement in CTS after graduation. Importantly, our programs have facilitated the careers of 31 women (39.7%) and 12 under-represented minorities (15.4%). We will present a breadth of qualitative data to inform which parts of the TL1-related programs have been successful, and which parts could use programmatic improvement to aid the transition into the physician-scientist workforce. DISCUSSION/SIGNIFICANCE OF IMPACT: Physician-scientist training barriers in the US have resulted in a shortage of these professionals in the clinical and translation workforce. Our data show the UR CTSI has been successful in addressing several of these challenges via the TL1-funded ART, MSTP, and ART/MSTP dual program pipeline.
4142 Implementation of Consent-to-Contact (CTC) initiative at an Academic Medical center: Initial operationalization and lessons learned
Authors: Lee Chin Chin , Blake Helenmarie M. , Canales Carlos A. , DeGennaro Stephen J. , Ramsingh Ishwar , Ransford Daru Lane , Schulman Carl I. , Wright Jonelle , Sacco Ralph L.
Published: July 2020

OBJECTIVES/GOALS: The objectives of this presentation are to discuss 1) the implementation of Consent to Contact at an Academic Medical Center; 2) the access to lists of potential participants by study teams; and 3) the challenges and adjustments made to the initial conceptualized process. METHODS/STUDY POPULATION: Participant recruitment is critical to the success of all research studies. It is particularly challenging when investigators do not have a patient population from which to recruit. Thus, the University of Miami launched the CTC initiative in 2016 to facilitate study recruitment. Study investigators can request access to a registry of participants who agreed to be contacted and meet the initial study eligibility criteria. A multidisciplinary Operational Committee provides oversight and regulates access to the CTC registry. RESULTS/ANTICIPATED RESULTS: The registry has over 110K patients who have agreed to be contacted for eligible research studies. The demographic distribution of the patients in the registry mirrors the diversity of the UHealth population. As of January 2018, when the registry became available to the research community, 25 study teams from different departments, including the All of Us Research Program, have requested potential participant lists. The process of requesting access to patient lists is adapted to studies’ needs, with particular reference to sensitive populations, such as HIV/AIDS, substance abuse, etc. Results on utilization and satisfaction of the CTC initiative are being collected and will be presented. DISCUSSION/SIGNIFICANCE OF IMPACT: The CTC initiative allows UHealth patients to opt-in to the registry for research studies. The Operational Committee continues to monitor the successful consent of patients to participate in individual research studies and improving the request process.

OBJECTIVES/GOALS: Youth and Families Determined to Succeed (YFDS), a non-profit organization in Hennepin County, MN, provides programs to address health disparities and increase health equity in diverse families. The objective of this capacity building community engaged research study was to identify factors and opportunities to expand YFDS. METHODS/STUDY POPULATION: A community partnered participatory research framework using 3 community engaged (CE) studies was conducted. This structured research process involves a facilitated discussion with a presentation on YFDS programming and a guided discussion with YFDS stakeholders. The theoretical foundation included constructs from the Model of Improvement and Health Belief Model. A trained qualitative research team led the discussion, took detailed notes, and used traditional content analysis to thematically code the notes (n = 29 pages). The studios were not audio recorded for confidentiality. Preliminary findings were presented to YFDS leadership with plans to present the results to YFDS stakeholders and families. RESULTS/ANTICIPATED RESULTS: A total of 16 YFDS past and current members participated in the studios. The average age was 42.5 years with 69% female and 75% black participants. The main themes were YFDS programming, outreach, and partnership. Participants mentioned YFDS youth “gained confidence”, found an additional family, and suggested ways to increase outreach and partnerships. Participants suggested YFDS increase their social media presence, create multicultural programing, partner with faith based organizations and schools, and determine new ways to evaluate health, social, and athletic gains. DISCUSSION/SIGNIFICANCE OF IMPACT: YFDS has positively impacted the lives of their families. With the use of CE studios, we have the opportunity to hear the voices of the members impacted that is necessary for capacity building community engaged research. We were able to find factors that made YFDS successful and suggestions to better improve and to increase positive wellness gains.

OBJECTIVES/GOALS: The Rockefeller University CCTS, Clinical Directors Network (CDN), and Carter Burden Network (CBN) received a DHHS-Administration for Community Living Nutrition Innovation grant to test whether implementation of DASH-concordant meals and a program to enhance self-efficacy, could lower blood pressure among seniors aging in place. METHODS/STUDY POPULATION: CEnR-Nav model to engage stakeholders, enroll seniors age >60 yr., eating 4 meals a week at 2 CBN congregate meal sites; Advisory Committee to facilitate dissemination; menus aligned with Dietary Approaches to Stop Hypertension (DASH) and New York City Department for the Aging (DFTA) nutritional guidelines; interactive sessions for education (nutrition, blood pressure, medication adherence); Omron 10 home BP devices for daily home monitoring. Plate Waste and Meal Satisfaction (Likert scale) to assess taste preference and cost impact. Outcomes: Primary: Change in Systolic BP at Month 1; change in percent with controlled blood pressure. Secondary: change in validated measures of cognitive (e.g. SF-12, PHQ-2), behavioral (Home BP monitoring), nutritional (food frequency) variables, satisfaction, costs. RESULTS/ANTICIPATED RESULTS: Menu alignment required multiple iterations. Plate Waste and Menu Satisfaction tools were developed. Site 1 enrollment began June 2019; educational sessions and home BP monitors and training were provided. Baseline mean blood pressure (Site 1) was 138/79 +20.5; (range: 7% hypertensive crisis, 36% stage 2 hypertension, 22% stage 1 hypertension, 22% elevated, and 13% normal). DASH-aligned meals began October 2019; Meal satisfaction declined briefly, chefs adjusted menus, and meal satisfaction rose to pre-intervention levels. Site 2 enrollment is ongoing; dietary intervention will start in 2020. Primary outcome data (change in BP) will be complete in March 2020. Secondary outcome data on social and behavioral impact of the interventions will also be presented. DISCUSSION/SIGNIFICANCE OF IMPACT: We leveraged our community-academic research partnership to conduct research addressing uncontrolled hypertension, an urgent unmet health need among seniors. The DASH Implementation Study can inform the broader aging services and healthcare community of the potential for congregate nutrition programs to improve cardiovascular health outcomes.
4449 Building Capacity in the Flint Community in the Midst of the Ongoing Water Crisis

Published: July 2020

OBJECTIVES/GOALS: Examining the impact of the Building Capacity for Research and Action (BCRA) Award created by the Community Engagement (CE) Program at the Michigan Institute for Clinical & Health Research (MICHR)--a Clinical & Translational Science Award (CTSA) site at the University of Michigan--in partnership with Community Based Organization Partners (CBOP). METHODS/STUDY POPULATION: The BCRA is a funding mechanism that supports new community-engaged research (CEnR) partnerships and projects that address community-identified health needs in Flint, Michigan. BCRA projects are required to be Flint-based and inclusive of both community and academic partners. A study section consisting of 10 MICHR-affiliated faculty and community partners reviewed proposals and made funding decisions. Funded teams were trained on Institutional Review Board (IRB) and reporting requirements by CE staff. MICHR provides support to BCRA-funded teams through monthly email correspondence with the CE Flint connector, budget review, mediation, regulatory assurance of IRB and the National Center for Advancing Translational Science (NCATS) requirements, coordinating six-month and final reporting, and hosting an annual stakeholder meet and greet. RESULTS/ANTICIPATED RESULTS: In 2017, the BCRA Award submitted its first request for proposals. It received 20 applications in 2018, and selected eight awardees, providing them with a total of $60,000 in funding. Four received $5,000 for partnership development and another four received $10,000 for their research projects. The BCRA Award received 16 applications in 2019, expanding its academic pool to include the University of Chicago, U-M Flint, Michigan State University, and Michigan State University-Flint in addition to the University of Michigan. Five recipients were selected and received a total of $45,000 in funding. One was awarded $5,000 for partnership development and another four were awarded $10,000 for their research projects. MICHR has invested over $100,000 in Flint through this mechanism, which was renewed in 2019. DISCUSSION/SIGNIFICANCE OF IMPACT: Each awardee presented at the annual stakeholder meet and greet. They showcased their projects with a brief overview and spoke about their expectations, lessons learned, partnership strengths and challenges, translational issues, and proposed next steps for subsequent grants, publications.
4508 Contextual Predictors of Hospitalization and Quality of Life Among Patients on Hemodialysis
Authors: Taylor Kathryn , Crews Deidra , Davidson Patricia
Published: July 2020

OBJECTIVES/GOALS: People engaging in high-risk substance use or experiencing food insecurity or housing instability are at increased risk to develop end-stage kidney disease. This study will examine associations between these risk factors, patient indicators of socioeconomic position, and hospitalization rates and quality of life after initiation of hemodialysis. METHODS/STUDY POPULATION: The proposed study will leverage a prospective cohort design. We will enroll a convenience sample of 330 participants from the same large dialysis organization. Participants will complete measures of socioeconomic position (age, gender, race, ethnicity, education, income, occupation and community poverty); substance use; food insecurity; housing instability; and quality of life at baseline. We will follow participants for 6 months and extract hospitalization counts from the dialysis facility medical record. RESULTS/ANTICIPATED RESULTS: We will generate risk scores (low, medium, high) from measures of substance use, food insecurity and housing instability. We will conduct multiple logistic regression to generate odds ratios comparing risk group membership by indicators of socioeconomic position. We anticipate that low or medium-risk groups will differ from high risk groups by indicators of socioeconomic position. We will conduct Poisson regression to generate incidence rate ratios for 6-month hospitalization rates comparing low or medium-risk and high-risk groups. Lastly, we will conduct multiple linear regression to generate beta coefficients for changes in quality of life scores comparing low or medium-risk and high-risk groups. We anticipate that high-risk groups will have higher hospitalization rates and lower quality of life scores. DISCUSSION/SIGNIFICANCE OF IMPACT: As the prevalence of end-stage kidney disease continues to increase, there is a need for tertiary prevention interventions that reduce costly inpatient utilization and improve health-related quality of life. The proposed study will lay groundwork for the development of interventions to improve patient outcomes and reduce Medicare spending.
