There has been an erosion of trust in medical care and clinical research, and this has raised issues about whether institutions and investigators conducting clinical research are worthy of trust. We review recent literature on research on trust and trustworthiness in the clinical research enterprise and identify opportunities to enhance trustworthiness, which will likely increase participant trust in clinical research. In addition, we review materials reporting the results of national polls related to the public’s trust in different occupations. The literature on trustworthiness and trust is complex and suffers from a lack of agreement on definitions of trust and trustworthiness and actions to enhance trustworthiness. Nonetheless, institutions need to take action to address the many elements that contribute to being perceived as trustworthy. As a complementary approach, since nurses have consistently ranked highest on trust by the public for twenty-two straight years, we analyze the features that likely account for the public’s uniform high regard for nurses. We propose specific actions to enhance the role of research nurses in the research enterprise, without compromising their primary role as participant advocates, that we have adopted at Rockefeller University to gain the benefits of the public’s trust in nurses in building trustworthiness.

Empowering the Participant Voice (EPV) is an NCATS-funded six-CTSA collaboration to develop, demonstrate, and disseminate a low-cost infrastructure for collecting timely feedback from research participants, fostering trust, and providing data for improving clinical translational research. EPV leverages the validated Research Participant Perception Survey (RPPS) and the popular REDCap electronic data-capture platform. This report describes the development of infrastructure designed to overcome identified institutional barriers to routinely collecting participant feedback using RPPS and demonstration use cases. Sites engaged local stakeholders iteratively, incorporating feedback about anticipated value and potential concerns into project design. The team defined common standards and operations, developed software, and produced a detailed planning and implementation Guide. By May 2023, 2,575 participants diverse in age, race, ethnicity, and sex had responded to approximately 13,850 survey invitations (18.6%); 29% of responses included free-text comments. EPV infrastructure enabled sites to routinely access local and multi-site research participant experience data on an interactive analytics dashboard. The EPV learning collaborative continues to test initiatives to improve survey reach and optimize infrastructure and process. Broad uptake of EPV will expand the evidence base, enable hypothesis generation, and drive research-on-research locally and nationally to enhance the clinical research enterprise.

OBJECTIVES/GOALS: Empowering the Participant Voice (EPV) is a Rockefeller-led 6-CTSA consortium that aims to collect research participant feedback through new Research Participant Perception Survey (RPPS)/REDCap infrastructure and data aggregation to a national database. Here we describe diverse Use Cases and launch dissemination to other hubs. METHODS/STUDY POPULATION: The EPV team refined the RPPS-S and developed fielding and data standards, a multi-lingual RPPS/REDCap project XML, At-a-Glance Dashboard, EPV Consortium Database, and Use Cases to align with local initiatives and stakeholder input. Sites ran full thread tests of the infrastructure before launch. To demonstrate RPPS/REDCap, 5 sites implemented Use Cases, surveyed diverse populations via email, patient portal or SMS, and analyzed results using the At-a-Glance Dashboard External module (which provides visual analytics and enables filtering by participant/study characteristics). Sites continue to collect, synthesize and respond to actionable data. To disseminate infrastructure, we will invite early adopters to implement the RPPS/REDCap infrastructure locally, joining the EPV learning collective. RESULTS/ANTICIPATED RESULTS: To date, 5 sites surveyed 10,199 research participants, at post-consent or end of study. 2833 (26%) research participants responded, from diverse demographic groups. More than 90% gave the Top Box score response regarding courtesy, respect for cultural background, privacy, and lack of pressure to join a study. Disparities were apparent in the informed consent experience, with a Top Box score range of 38-78% in different demographics. Dissatisfaction with out-of-pocket research costs was a recurring theme. Top Box scores varied for feeling like a valued partner in research (69-93%), would recommend research participation to friends or family (56%-81%), and Overall Experience (64%-90%) questions. Sites identified actionable findings in areas of consent, communication, partnership, and study conduct. DISCUSSION/SIGNIFICANCE: The EPV RPPS/REDCap infrastructure enabled sites to broadly collect participant feedback, identify actionable findings and make inter-institutional comparisons. Collaborators are designing local initiatives to increase response rate and diversity, address disparities in research participation experiences, and discover better practices.

OBJECTIVES/GOALS: Six CTSA sites formed a collaboration to DEVELOP, DEMONSTRATE, AND DISSEMINATE new infrastructure to streamline collection and analysis of research participant feedback, using the Research Participant Perception Survey (RPPS), common standards, and customized REDCap-based tools, to improve the clinical research enterprise. METHODS/STUDY POPULATION: DEVELOP charter, consensus approach, core survey, deployment standards, data-use agreements; define meta-data, system requirements for the infrastructure, use-cases. Engage stakeholders for broad institutional and community input. Build RPPS/REDCap project, visual analytics Dashboard External Module, and Program Dashboard module for evaluation. Configure to use with Multilingual Module. DEMONSTRATE by implementing site-based use cases that reflect local priorities and span diverse populations, testing different methods of survey deployment (REDCap, patient portal, SMS) to showcase utility and flexibility. Generate data for local and inter-institutional benchmarking. Refine, then DISSEMINATE new infrastructure across the Consortium and REDCap community for broader testing and uptake. RESULTS/ANTICIPATED RESULTS: The project team refined the RPPS survey for inclusivity and mode of informed consent; defined standards for survey timing, sampling, and study metadata; configured the data dictionary in English and Spanishfor use with the multi-lingual module ; developed tools for project evaluation. Stakeholder engagement identified themes of anticipated value and fears about feedback. We designed an At-a-Glance Dashboard to display survey results with detailed analytics and filters. A REDCap application programming interface will send de-identified site data to the EPV Consortium Database to support benchmarking. Full implementation began November 2021 and will scale in 2022. Dissemination to Consortium and REDCap users is ongoing through presentations and a project website (www.Rockefeller.edu/research/epv). DISCUSSION/SIGNIFICANCE: Direct feedback from representative populations about their experiences in research is essential to understand and resolve barriers to broad participation in research. Streamlined RPPS/REDCap infrastructure provides a platform for local and national benchmarking, and collection of actionable data to improve clinical research.

OBJECTIVES/GOALS: To test whether implementing DASH-aligned meals in a congregate meal program, combined with Self-Measured Blood Pressure (SMBP) monitoring, lowers systolic blood pressure in community-living seniors at two senior centers. Secondary Aims included cognitive and behavioral change, and attention to client preferences. METHODS/STUDY POPULATION: The Carter Burden Network (CBN) provides services and congregate meals to older adults in NYC, many with low income, and unmet health needs. Eligible participants at two CBN sites, aged 60 or older and consuming >4 congregate meals/week, were recruited. After baseline assessments, participants received DASH-aligned meals onsite, education on nutrition and BP management, and personal devices and support for self-measured blood pressure (SMBP) monitoring. Primary outcome data (BP measured by health professional) was collected at Month 1, with secondary assessments at Months 3 and 6. Staff downloaded SMBP data regularly. Study surveys tracked cognitive and behavioral changes. Qualitative feedback from a project Advisory Committee, participants and study partners was collected throughout implementation. RESULTS/ANTICIPATED RESULTS: 97 Participants enrolled (49% White, 32% Black, 19% Other races; mean age 73). At Baseline, 67% were overweight/obese; 80% were hypertensive (32% Stage I; 48% Stage 2). Primary outcome: Mean change in systolic BP at Month 1 compared to Baseline, was -4.41 mmHg (n= 61; p=0.07). By multiple regression analysis, change in BP at Month 1 was associated with BMI, age, and baseline blood pressure (p= .02, .04, .00, respectively). SMBP: Mean change in systolic SMBP by End-of-Study was -6.9 mmHg (p=.003). 56% participants completed SMBP through Month 1 and 30% to End-of-Study. Mean frequency of > 1 SMBP measure/day was 3 days/week. Women (n= 22, 88%) and Black participants (n= 15, 60%) were more likely to continue taking their home blood pressure measurements to End-of-Study (p=.002, p=.037, respectively). DISCUSSION/SIGNIFICANCE: This study provides the first data to support the potential of DASH as part of an effective community-implemented program for seniors and demonstrates the feasibility of implementing a multi-component intervention using existing congregate meal programs at senior centers that can reach minority and low-income communities.

OBJECTIVES/GOALS: Dietary approach to stop hypertension (DASH) is a proven intervention to treat hypertension. Despite years of research the immediate physiologic response to its implementation was never characterized.This translational trial describes the biological pathway from nutrition through hormons, urine electrolytes and blood pressure reduction. METHODS/STUDY POPULATION: A single center interventional trial. Stage 1 hypertensive otherwise healthy volunteers were admitted for 14-days, transitioning from American style diet to DASH diet. Nutritional habits were assessed with food frequency questionnaires, and menus designed according to the guidelines of the National Heart Blood and Lung Institute (NHBLI) of the National Institute of Health (NIH). Data were collected daily for vital signs, blood and urine. Participants completed two 24-hour ABPM on days 1,10, and two 24-hour urine collections in parallel. We conducted a follow up visit two weeks after discharge. RESULTS/ANTICIPATED RESULTS: 9 volunteers (78% male, 89% Black individuals) completed the protocol. During an inpatient stay, they consumed a mean daily potassium intake of 5.6 g (±0.7g) and 2.6 g (±0.3g) of Sodium. Serum Aldosterone increased from day 0 (mean 8.3, range 2.8-18.9) to day 5 (mean 17.8, range 10.2-27.2) after intervention, and decreased on day 11 (mean 11.5, range 4.8-18.2) despite continuous exposure (p-value=0.002). The urine electrolyte ratio of ([Na]/[K]) decreased from a mean of 3.5 before intervention to 1.16 on day 4, creating a statistically significant slope (p-value<0.001). Blood pressure by 24-hour ABPM decreased by 3.7 mmHg systolic BP and 2.3 mmHg diastolic BP from day 1 to 10 for the entire period, and for measures taken during sleep or awake time, assessed separately. DISCUSSION/SIGNIFICANCE: Shifting from a high-sodium low-potassium diet to the opposite composition leads to serial physiological changes that are governed by aldosterone and result in blood pressure reduction. Urine electrolyte ratio reflects nutritional changes within 4 days of transition and should guide clinicians in assessing lifestyle modification adherence.

Clinical trials continue to face significant challenges in participant recruitment and retention. The Recruitment Innovation Center (RIC), part of the Trial Innovation Network (TIN), has been funded by the National Center for Advancing Translational Sciences of the National Institutes of Health to develop innovative strategies and technologies to enhance participant engagement in all stages of multicenter clinical trials. In collaboration with investigator teams and liaisons at Clinical and Translational Science Award institutions, the RIC is charged with the mission to design, field-test, and refine novel resources in the context of individual clinical trials. These innovations are disseminated via newsletters, publications, a virtual toolbox on the TIN website, and RIC-hosted collaboration webinars. The RIC has designed, implemented, and promised customized recruitment support for 173 studies across many diverse disease areas. This support has incorporated site feasibility assessments, community input sessions, recruitment materials recommendations, social media campaigns, and an array of study-specific suggestions. The RIC’s goal is to evaluate the efficacy of these resources and provide access to all investigating teams, so that more trials can be completed on time, within budget, with diverse participation, and with enough accrual to power statistical analyses and make substantive contributions to the advancement of healthcare.

ABSTRACT IMPACT: Our implementation model translates two evidence-based nutritional and behavioral interventions to lower blood pressure, into a community-based intervention program for seniors receiving congregate meals. OBJECTIVES/GOALS: The Rockefeller University, Clinical Directors Network, and Carter Burden Network received an Administration for Community Living Nutrition Innovation grant to test whether implementation of DASH-concordant meals and health education programs together lower blood pressure among seniors aging in place. METHODS/STUDY POPULATION: n=200, >60 yr, >4 meals/week at CBN; engagement of seniors/stakeholders in planning and conduct; Advisory Committee to facilitate dissemination; menus aligned with Dietary Approaches to Stop Hypertension (DASH) and NYC Department for the Aging nutritional guidelines; interactive sessions for education in nutrition, BP management, medication adherence. Training in use of automated daily home BP monitors (Omron 20). Validated surveys at M0, M1, M3, M6. Taste preference and cost assessed through Meal Satisfaction (Likert scale) and Plate Waste measures. Primary Outcome: Change in Systolic BP (SBP) at Month 1; change in %BP controlled. Secondary: validated cognitive, behavioral, nutritional measures (SF-12, PQH-2), economics; staff/client satisfaction, trends and significant associations. RESULTS/ANTICIPATED RESULTS: n=94, x2 age =73 +/- 8 years, 65% female, 50% White, 32% Black/African American, 4% Asian, 1% American Indian, Alaskan Native, 13% Other, 32% Latino/a, 43% with income <$20,000. Mean SBP at Baseline was 137.87 +18.8 mmHg (range 98-191). Menus were adapted to provide 20% daily DASH requirements at breakfast, 50% at lunch. Participants attended classes in nutrition and medication management and were provided with and trained to use an automated home BP monitor. Meal satisfaction scores dipped briefly then met or exceed pre-DASH levels. Home BP data was downloaded every 2-4 weeks with social/behavioral support. The COVID-19 closures interfered with BP outcome data collection and meal service ceased. Primary outcome: x2 change in SBP at Month 1 = -4.41 mmHg + 18 (n=61) (p=0.713). Significant associations will be reported. DISCUSSION/SIGNIFICANCE OF FINDINGS: Our community-academic research partnership implemented the DASH diet in congregate-meal settings to address uncontrolled hypertension in seniors. COVID-19 interrupted the study, but encouraging trends were observed that may inform refinement to this community-based health intervention for seniors.

ABSTRACT IMPACT: Understanding the mechanism underlying the DASH diet may shed light on the physiologic process by which nutrition influences blood pressure and potentially lead the way to new therapeutics that target ion channels. OBJECTIVES/GOALS: Hypertension is a disease of the westernized world, as it stems from lifestyle habits. Lower salt consumption reduces blood pressure, yet DASH diet is much more effective, lowering blood pressure as efficiently as one anti-hypertensive drug. The precise mechanism through which DASH achieves its effect is not understood, and this is the project goal. METHODS/STUDY POPULATION: We hypothesize that exposing hypertensive volunteers to a high potassium and low sodium DASH diet will change the composition of renal ion channel in an aldosterone-dependent manner, leading to excretion of both sodium and potassium and a reduction in blood pressure. To assess how the nutritional change changes ion channel composition in the kidneys’ epithelium in aldosterone-induced manner, we will monitor urine exosomes, which contain epithelial cell membranes. We designed an in-hospital nutritional studies recruiting 20 volunteers. Patients will consume carefully designed menu, and measurements will be collected daily: blood pressure, biologic samples including blood and urine electrolytes, aldosterone, and urine for exosomes. RESULTS/ANTICIPATED RESULTS: We have collected data from 5 research volunteers so far.following exposure to the high potassium diet, Aldosterone blood levels increased while blood level of both potassium and sodium was maintained within normal limits. Urinary ratio of electrolytes, sodium:potassium was reversed 5-7 days following nutritional change from 6 to 1. Both manual and automated 24-hour blood pressure measurements confirmed blood pressure reduction following nutritional change. The following illustrates the impact the diet had on a participant’s 24-hour ambulatory blood pressure. Daily mean blood pressure was reduced from 120/76 mmHG to 112/68, mean awake blood pressure was reduced from 125/80 mmHG to 117/72 mmHG, and mean sleep blood pressure was reduced from 112/69 to 103/60 mmHG DISCUSSION/SIGNIFICANCE OF FINDINGS: Understanding the mechanism underlying the DASH diet may shed light on the physiologic process by which nutrition influences blood pressure and potentially lead the way to new therapeutics that target ion channels. By introducing our participants to a healthier lifestyle, they could maintain lower blood pressure without requiring medication.

The recipients of NIH’s Clinical and Translational Science Awards (CTSA) have worked for over a decade to build informatics infrastructure in support of clinical and translational research. This infrastructure has proved invaluable for supporting responses to the current COVID-19 pandemic through direct patient care, clinical decision support, training researchers and practitioners, as well as public health surveillance and clinical research to levels that could not have been accomplished without the years of ground-laying work by the CTSAs. In this paper, we provide a perspective on our COVID-19 work and present relevant results of a survey of CTSA sites to broaden our understanding of the key features of their informatics programs, the informatics-related challenges they have experienced under COVID-19, and some of the innovations and solutions they developed in response to the pandemic. Responses demonstrated increased reliance by healthcare providers and researchers on access to electronic health record (EHR) data, both for local needs and for sharing with other institutions and national consortia. The initial work of the CTSAs on data capture, standards, interchange, and sharing policies all contributed to solutions, best illustrated by the creation, in record time, of a national clinical data repository in the National COVID-19 Cohort Collaborative (N3C). The survey data support seven recommendations for areas of informatics and public health investment and further study to support clinical and translational research in the post-COVID-19 era.

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.

OBJECTIVES/GOALS:

1. 1. Examine the associations among BMI and markers of cardiometabolic risk, including blood pressure, lipids and blood glucose.

2. 2. Assess prevalence of kidney function deterioration, identified as hyperfiltration and moderately increased albuminuria (MIA), in obese compared to normal weight adolescents.

METHODS/STUDY POPULATION: De-identified electronic health records (EHR) data were extracted for female adolescents, aged 12-21 years, and their offspring through 24 months, who received health care services (Jan 2012 to Dec 2016) in NYC from 12 academic health centers and community health centers that are part of PCORnet NYC Clinical Data Research Network (NYC-CDRN). Data were analyzed using SAS (version 3.2.5). Patient characteristics overall and for study subgroups were examined using standard summary statistics. Trends in cardio-renal variables were examined by BMI groups coded according to NHANES as underweight, normal weight, overweight or obese. Multiple linear regression analyses will control for covariates. RESULTS/ANTICIPATED RESULTS: Data from 651,066 adolescent females ages 12-21 were retrieved. Analysis was performed on a subset of 202,214 unique patients (26% white, 15% black, 12.9% Latina) for whom there was complete data for BMI and blood pressure. Distribution of BMI was 6% underweight, 59% normal weight, 19% overweight, and 17% obese. There were significant differences in mean systolic (SBP, mean±SD mmHg: 102±12, 108±11, 112±12, 116±12) and diastolic blood pressure (DBP, mean±SD mmHg: 62±10, 66±8, 68±8.9, 70±9) across the four BMI groups with an increasing trend (p-values<0.0001). We will examine renal function trends, and whether these cardio-renal differences persist when controlling for age, race and ethnicity. DISCUSSION/SIGNIFICANCE OF IMPACT: Although SBP/DBP means were within normal limits across BMI groups, significant increasing trends suggest that women in higher BMI groups may be at increased risk for hypertension and potentially for renal dysfunction. We will examine contributions of race/ ethnicity and age to these associations.

OBJECTIVES/GOALS:

1. 1. analyze urinary protein exosome content pattern before and during DASH diet.

2. 2. characterize urine electrolyte changes associated with changes in protein profiles, and hormonal changes before/after DASH diet.

3. 3. analyze the association of these changes to the DASH-related BP response.

METHODS/STUDY POPULATION: In this proof of concept study, hypertension stage 1 volunteers will receive a DASH based menu during 14 consecutive days of elective admission to the RU research hospital. Participants will complete a food frequency questionnaire (VioScreen) with a bionutritionist. Throughout the intervention period, participants will be assessed for blood pressure, plasma renin and aldosterone, and 24 hour urines for electrolytes, creatinine, protein, albumin and first morning urine collected for exosomes. Exosome analysis will be performed by a commercial lab. Proteome analysis will be conducted in the RU Mass-spectrometry service. RESULTS/ANTICIPATED RESULTS: The causal pathway we will elucidate hypothesizes that: 1) changes in diet affect blood electrolytes, and through these, aldosterone. 2) Aldosterone alters the expression of specific transporter proteins in the renal tubule; protein expression will be reflected in the urine exosome. 3) These transporters affect the excretion of electrolytes, as reflected by urinary ratio of sodium (Na) to Potassium (K). During consumption of the Western diet, the Na/K ratio is approximately 2-2.5, whereas we expect the urinary sodium/potassium ratio to be <1, when the participant is eating a DASH based diet. DISCUSSION/SIGNIFICANCE OF IMPACT: This assay provides a clinical tool to assess dietary adherence, and the project will provide insights into the mechanism whereby DASH reduces blood pressure.

OBJECTIVES/GOALS: Innovations with positive health impact are a high priority for NCATS and CTSAs. Program design that uses the Causal Pathway approach incorporates performance indicators that assess impact. We applied Causal Pathway thinking to an ongoing national program to enhance the evaluation of program impact. We report Lessons Learned. METHODS/STUDY POPULATION: We conducted a day-long onsite workshop to introduce the model to the project team, build capacity, and map the existing program elements to Logic Models representing program Specific Aims. A local Causal Pathway (CP) champion was identified. Alignment of the Logic Models with the CP approach (input→activities→ outputs→effects/impact) developed iteratively through biweekly, then monthly conferral among stakeholders. Key tasks included distinguishing among activities, outputs, and effects (impacts), and identification of performance indicators for each stage of the Causal Pathway. Visualization tools and an additional late stage half-day workshop were used to foster consensus. Implementation of the CP model tested the feasibility of collecting specific indicators and prompted model revisions. RESULTS/ANTICIPATED RESULTS: Program leadership and team members (n = 30) participated in the kick-off workshop. Four Specific Aims were mapped to Logic Models. Multiple Causal Pathway (CP) diagrams, one for each project in the program, were developed and mapped to Aims. Alignment of CP threads to Aims and identification of performance indicators required iteration. CP threads converged onto common final Impacts, sometimes crossing to another Aim. Performance indicators for operations were readily accessible to team members, and less so for impacts. Assumptions about program effects were subjected to specific indicators. Over time, Leadership noticed more expression of CP thinking in daily activities. New projects developed during this period incorporated the CP approach. Teams were able to streamline and simplify Logic/CP models. DISCUSSION/SIGNIFICANCE OF IMPACT: Through capacity-building and mentored exercises, an innovation team was able to infuse CP thinking into the evaluation of their ongoing program. The CP approach to design and evaluation maps progress and indicators across the life of a program from initial activities to its ultimate impact.

OBJECTIVES/GOALS: There is universal recognition of the importance of team science and team leadership. We have developed a semi-quantitative translational science specific team leadership competency assessment tool and have begun implementation studies to assess the impact of personalized feedback on the team science leadership skills of KL2 Clinical Scholars. METHODS/STUDY POPULATION: To create the instrument, we employed a modified Delphi approach by conducting a thorough literature review on Leadership to concretize the relevant constructs, then used these extracted constructs as a springboard for the Rockefeller Team Science Educators (TSE’s) to discuss and refine the leadership domain areas, collectively create domain-specific survey items. Further discussion helped refined the number, grouping, and wording. Scholars also contributed feedback in item development. We piloted the Leadership Survey by having all of the Rockefeller TSEs rate Clinical Scholars, and having each Scholar rate themselves. Each item was answered using a six-point Likert scale where a low score indicated poor expression and a high score represented excellent expression of the specific leadership attribute. RESULTS/ANTICIPATED RESULTS: Incorporation into a REDCap data base made consenting and rating process by TSE’s and the Scholars straightforward. The a priori domains (Foundational Leadership Competencies, Professionalism, Team Building and Team Sustainability, Appropriate Resource Use and Study Execution, and Regulatory Accountability) had high internal validity and good internal factor structure. The congruence between TSE and Scholar self-ratings were uniformly high, and discordance was often a function of “confidence” and “modesty” on the part of the scholar, rather than deficiency. Supporting comments were informative about performance barriers and mechanisms for improvement. Return of results allowed for the exploration of training gaps. Scholars were surveyed to gauge their reaction to the formal feedback. DISCUSSION/SIGNIFICANCE OF IMPACT: This quantification of team science leadership constructs has allowed for A)- the articulation of constructs essential for successful Translational Scientists to acquire during their training, B)- identification of gaps in that training and skill set, and C)- mechanisms for bolstering any identified gaps in these essential leadership constructs.
