OBJECTIVES/GOALS: This integrated knowledgetranslationproject aims to increase youth engagement in mental health services through enhancing shared decision-making processes. To do this, a knowledge product to support greater involvement in measurement-based care practices will be evaluated and co-developed with youth study participants. METHODS/STUDY POPULATION: This study population includes youth (aged 12-25) with lived/living experience of accessing mental health services through an integrated service delivery model in Ontario. Study methods focus on co-designing a knowledge product with youth partners guided by the Knowledge-to-Action (KTA) Framework. The prototype knowledge product addressing identified barriers to MBC understanding, will be quantitatively evaluated by study participants. Through semi-structured focus groups, qualitative perspectives of the intervention’s impact on shared decision-making and overall engagement in treatment will be collected. The study’s design ensures active collaboration with the study population and aims to enhance MBC understanding and engagement in mental health care among youth. RESULTS/ANTICIPATED RESULTS: We anticipate increased youth involvement within MBC practices, and overall increased engagement in shared-decision making in treatment. We anticipate the developed knowledge product will enhance youth’s understanding of MBC, foster dialogue between youth and clinicians, and promote active involvement and informed decision-making in their mental health treatment. By involving youth in the co-design process, our project is poised to foster a sense of ownership and relevance, ultimately improving youth engagement, decision-making, and mental health outcomes within integrated mental health services. DISCUSSION/SIGNIFICANCE: Youth deserve to have an active role in shaping treatment decisions. This tool may bridge a gap by equipping youth with the knowledge needed to engage in decisions that are often practitioner-led. This study will discuss the impact and strategies for increasing involvement in MBC practices on youth engagement within treatment.

OBJECTIVES/SPECIFIC AIMS: Family centered rounding on pediatric inpatient units improves communication and family satisfaction. While the use of electronic medical record based devices and resources as part of the rounding process allows for immediate access of information and real time order management, there is limited data concerning parental perspectives’ about technology use on rounds, and about factors affecting participation during family centered rounds more generally. Our objectives were to examine parental (1) perspectives on factors that affect their participation during family centered rounds and (2) resource preference (tablet, computer on wheels, paper notes) used by trainees and the reasons for said preference. METHODS/STUDY POPULATION: We performed a cross-sectional study with English-speaking parents who were present for multidisciplinary family centered rounds and whose children were admitted to the inpatient pediatric unit at a tertiary care academic medical center. Parents were surveyed after rounds to ascertain their opinions on factors affecting their participation in rounds, preferences in respect to the resource used by trainee, and whether they believed the resource used on rounds that day affected their understanding or participation in rounds. Parents were also asked to articulate the reasons behind their preferred resource. Responses were analyzed using descriptive statistics, and qualitative responses were analyzed for themes. RESULTS/ANTICIPATED RESULTS: In total, 40 parents enrolled. Common responses regarding factors affecting parental participation included: information was explained in way that was easy to understand (90%), parents’ understanding of the medical information (85%), eye contact with the medical team (78%), if the medical team asks for parent input (75%), and the health of the child (70%). Fewer parents (23%) believed that the type of resource used affected their participation. Tablets were the preferred technology resource (33%) due to their portability, ease of accessing information, and that they encouraged interaction with the patient. Fewer preferred computers on wheels (27%) and paper notes (5%). In total, 35% of parents reported no preferred resource. No parents said that tablets were their least preferred resource. Reasons computers on wheels were least preferred (13% of parents) included their large size and that they limited eye contact, whereas, parents stated that paper notes were least preferred (13% of parents) because they were old-fashioned, easy to lose, and not accurate; 68% of parents stated the resource used did not affect their understanding on rounds that day, and 83% asserted the resource had no effect on participation. DISCUSSION/SIGNIFICANCE OF IMPACT: Clear and engaging communication during family centered rounds is most important to parents’ participation. The type of technology resource used is less relevant, but parents favor the use of tablets when they report a preference. Given the convenience for providers, tablet utilization as part of a family centered, trainee based rounding process has potential benefit.

ABSTRACT IMPACT: Many who suffer from end-stage organ disease do not qualify for solid organ transplantation because of obesity; however, bariatric surgery offers the potential to render select patients transplant-eligible, and in some cases, may lead to weight loss that is sufficient to reverse end-stage organ disease. OBJECTIVES/GOALS: As obesity prevalence grows, more end-stage organ disease patients will be precluded from transplant. Numerous reports suggest bariatric surgery in end-stage organ disease may help patients achieve weight loss sufficient for transplant listing, though the published data are limited. METHODS/STUDY POPULATION: We performed a systematic review/meta-analysis of studies of bariatric surgery to achieve solid organ transplant listing. RESULTS/ANTICIPATED RESULTS: Among 82 heart failure patients, 40.2% lost sufficient weight for listing, 29.3% were transplanted, and 8.5% had sufficient improvement with weight loss they no longer required transplantation. Among 28 end-stage lung disease patients, 28.6% lost sufficient weight for listing, 7.1% were transplanted, and 14.3% had sufficient improvement following weight loss they no longer required transplant. Among 41 cirrhosis patients, 58.5% lost sufficient weight for listing, 41.5% were transplanted, and 21.9% had sufficient improvement following weight loss they no longer required transplant. Among 288 end-stage/chronic kidney disease patients, 50.3% lost sufficient weight for listing and 29.5% were transplanted. DISCUSSION/SIGNIFICANCE OF FINDINGS: Small sample size and publication bias are limitations; however, bariatric surgery may benefit select end-stage organ disease patients with obesity that precludes transplant candidacy.

Objectives/Goals: To explore how CTSA-supported research is cited and used in policy documents by applying Yu et al.’s (2023) coding framework. We aim to move beyond citation counts by examining how research engages with policy and identifying substantive examples of research informing policy decisions. Methods/Study Population: We will use Overton to identify CTSA-supported publications with the highest number of policy citations. For these highly cited publications, we will conduct a content analysis of the citing policy documents using Yu et al.’s (2023) motivation codes. These five codes classify how research is used in policy documents – from background context to supporting arguments or forming the policy evidence base – and help distinguish citations that reflect more versus less substantive research-to-policy engagement. We will then analyze coded data with Overton metadata (e.g., citing organization characteristics) to identify emerging patterns and assess whether substantive uses of research provide compelling examples of CTSA impact on policy. Results/Anticipated Results: We will report how CTSA-supported research is used in policy documents. This analysis will identify more meaningful examples of research engagement in policy – publications that inform or shape policy decisions versus those cited for background context. By linking these codes with Overton fields, such as citing organization characteristics, we will explore whether more meaningful uses of research are associated with specific organization types or sectors. Findings will offer preliminary insight into whether analyzing research use in policy documents can help evaluators identify strong examples of CTSA impact. Discussion/Significance of Impact: This study applies methods from scientometric policy citation analysis and builds on a growing focus within the CTSA program on research’s role in shaping policy. It moves beyond citation counts to identify meaningful cases of CTSA-supported research influencing policy and demonstrating impact.

Objectives/Goals: To identify and characterize future potentially high impact research generated by the Clinical and Translational Science Awards (CTSA) Program, we evaluated the Altmetric Attention Scores (AAS) of recent articles associated with the Program and conducted an initial assessment of the attributes associated with high AAS for Program articles. Methods/Study Population: We used the NIH Query, View, Report (QVR) tool to identify recently-published scientific papers that cited support from a CTSA Program grant. The unique publications identified by QVR were used to construct an Altmetric Explorer report. We examined the relationship between the AAS and other variables, including number of authors, number of grants supporting the publication, number of CTSA program institutions supporting the publication, and if the publication included group authorship. Results/Anticipated Results: Our analyses confirmed that the Program indeed supports potentially high impact research, as indicated by the highest scoring papers, across a wide range of diseases and conditions. Nearly all the highest scoring papers were focused on a specific disease or condition rather than broader methodological research, despite the disease-agnostic focus of the CTSA program. We also found that the Program significantly contributed to critical research on the once-in-a-century COVID-19 pandemic. We confirmed the entire CTSA consortium is contributing to potentially high impact research, with all institutions represented in the highest scoring publications. Discussion/Significance of Impact: Understanding the impact of the CTSA Program presents a unique challenge – the program supports biomedical research infrastructure and training programs whose outcomes and impact can be difficult to track or measure. These data offer early signals of impact and can assist evaluators with designing future evaluations.

OBJECTIVES/GOALS: Low and middle income countries (LMICs) face challenges in early detection of breast cancer resulting in high breast cancer mortality. This study serves to identify gaps and opportunities for innovators seeking to address problems in early detection of breast cancer in Uganda and other LMICs. METHODS/STUDY POPULATION: Two methods were used: 1) Three weeks of ethnographic research in Uganda through primary stakeholder interviews and clinical observations. Interviews were conducted with patients, clinicians, NGOs, and key opinion leaders from the Uganda Cancer Institute, Makerere University, and JHPIEGO. Clinical observations were performed to note the workflow and availability of resources across diverse health centers ranging from village health teams in rural settings to the national referral hospital in the urban center. 2) A targeted literature search focused on breast cancer detection in LMICs. Keywords included breast cancer’, screening’, and diagnosis’. Identified challenges were validated through stakeholder interviews and categorized. Potential solutions to each challenge were explored. RESULTS/ANTICIPATED RESULTS: Three broad categories of challenges and suggested innovation targets were identified. 1) Ineffective clinical processes: deskilling and improving training around the process of clinical breast examinations, imaging operation and interpretation, and pathology preparation and interpretation; 2) Accessibility: increasing screening throughput, improving rural community access to breast cancer care, and increasing opportunistic screening; 3) Sensitization: increasing patient and health worker awareness of clinical presentations of breast cancer, reducing cultural barriers, and improving trust in the medical community. DISCUSSION/SIGNIFICANCE: Innovators seeking to solve problems in early breast cancer detection in LMICs should focus on ineffective clinical processes, accessibility, and sensitization. In conjunction with prompt treatment, there is potential to reduce breast cancer mortality rates in line with the Global Breast Initiative.

The COVID-19 pandemic has required many clinical and translational scientists and staff to work remotely to prevent the spread of the virus. To understand the impact on research programs, we assessed barriers to remote work and strategies implemented to support virtual engagement and productivity. A mixed-methods RedCap survey querying the remote work experience was emailed to Colorado Clinical and Translational Sciences Institute (CCTSI) scientists and staff in April 2020. Descriptive analyses, Fisher’s Exact tests, and content analysis were conducted. Respondents (n = 322) were primarily female (n = 240; 75%), 21–73 years old (mean = 42 years) with a PhD (n = 139; 44%) or MD (n = 56; 55%). Prior to COVID-19, 77% (n = 246) never or rarely (0–1 day a week) worked remotely. Remote work somewhat or greatly interfered with 76% (n = 244) of researchers’ programs and 71% (n = 231) reported slowing or stopping their research. Common barriers included missing interactions with colleagues (n = 198; 62%) and the absence of routines (n = 137; 43%). Strategies included videoconferencing (n = 283; 88%), altering timelines and expectations (n = 180; 56%). Scientists and staff experienced interference with their research when they shifted to remote work, causing many to slow or stop research programs. Methods to enhance communication and relationships, support productivity, and collectively cope during remote work are available.

Electronic platforms provide an opportunity to improve the informed consent (IC) process by permitting elements shown to increase research participant understanding and satisfaction, such as graphics, self-pacing, meaningful engagement, and access to additional information on demand. However, including these elements can pose operational and regulatory challenges for study teams and institutional review boards (IRBs) responsible for the ethical conduct and oversight of research. We examined the experience of two study teams at Alzheimer’s Disease Research Centers who chose to move from a paper-based IC process to an electronic informed consent (eIC) process to highlight some of these complexities and explore how IRBs and study teams can navigate them. Here, we identify the key regulations that should be considered when developing and using an eIC process as well as some of the operational considerations eIC presents related to IRB review and how they can be addressed.

Objectives/Goals: Multiple sclerosis (MS) is an autoimmune disease located within the central nervous system. Evidence suggests nutrition may affect MS progression, but intervention research remains early. This study aims to identify barriers to dietary adherence hindering successful translation of dietary interventions into large-scale effectiveness studies. Methods/Study Population: We are currently conducting the Functional Outcomes of Diet in Multiple Sclerosis (FOOD for MS) study, a randomized controlled feeding trial testing the efficacy of two diet interventions for improving symptoms of MS. Participants who complete FOOD for MS will be invited to complete an individual interview. We will use a semi-structured interview guide based on the Health Action Process Approach to complete the interviews. Interviews will be recorded via Zoom, transcribed using Microsoft 365 transcription, and thematically analyzed using NVivo Software to derive themes related to diet adherence. Results/Anticipated Results: Study findings will describe key themes related to barriers and facilitators of long-term adherence to the FOOD for MS diets. Anticipated barriers may relate to study structure and dietary maintenance, while potential facilitators may involve behavioral supports and study incentives. Participants will also provide recommendations for enhancing the behavioral support components of the intervention to promote sustained adherence. Discussion/Significance of Impact: Results from this qualitative interview will guide refinement to the FOOD for MS protocols and support the development effectiveness and implementation trials.

ABSTRACT IMPACT: Up to 33% of patients of patients who undergo reconstruction have hostile defects with coexisting soft tissue and osseous defects due to prior radiation, prior failed cranioplasty or concurrent infections we seek to identify optimal strategies for these patients based on the experience of a southeastern tertiary referral center. OBJECTIVES/GOALS: Scalp and calvarial defects in patients may result from a number of etiologies including trauma, burns, tumor resections, infections, osteoradionecrosis, or congenital lesions. Our objective was to retrospectively evaluate the use of alloplastic reconstruction alongside autologous reconstruction for high risk cranial defects. METHODS/STUDY POPULATION: An IRB approved retrospective review of patients who underwent cranioplasty of a hostile site at a Southeastern tertiary referal center between January 2008 and December 2018 was performed. The patients were stratified into three groups based on the type of implant used: autogenous (bone), alloplastic (PEEK, Titanium, PMMA), or mixed (combination of both types of graft). The primary outcome metric was a complication in the year following cranioplasty, identified by flap or bone graft failure, necrosis, or infection. Statistical analysis included t-tests and chi-square tests where appropriate using SPSS. RESULTS/ANTICIPATED RESULTS: There were 43 total cases in this time period; 15 autogenous, 23 alloplastic, and 5 mixed. The purely autogenous group had the highest complication rate (85%) and the alloplastic group had the lowest complication rate (38%). When stratified by specific material used for reconstruction (15 bone, 14 PEEK, 10 titanium, and 5 PMMA), overall complication rate was statistically significant (p=0.009; chi square test) with PEEK implants having the lowest complication rate (21%). The analysis documented an overall complication rate that was statistically different between the three groups (p=0.012). DISCUSSION/SIGNIFICANCE OF FINDINGS: This analysis interestingly found that in the setting of hostile cranial defects, cranioplasties would benefit from the use of prosthetic implants instead of autologous bone grafts, not only for avoidance of donor site morbidity but also for decrease in overall complications.

OBJECTIVES/SPECIFIC AIMS: The current pilot study will use a mixed methods approach to investigate the role of psychological mechanisms in the relationship between food insecurity and obesity. We will be the first to assess 4 key psychological constructs (delay discounting, grit, future time perspective, and subjective social status) in a sample of food secure and food insecure adults with and without obesity. The specific aims are: (1) Examine associations among psychological mechanisms, food security status, and body mass index (BMI); and (2) Collect qualitative data on psychological mechanisms linking food insecurity and BMI. METHODS/STUDY POPULATION: This is a cross-sectional, observational pilot study that will be conducted in the local Baton Rouge community. The target study sample is 56 food secure and food insecure women and men aged 18–49 years with a BMI of 20.0 kg/m2 or greater. Independent (grouping) variables are food security status and BMI. Primary endpoints are 4 psychological constructs measured via questionnaires: (1) delay discounting, (2) grit, (3) future time perspective, and (4) subjective social status. We will also assess a number of key covariates, including health literacy, sociodemographics, food assistance use, and dietary quality. Semistructured, in-depth interviews will be conducted in a subsample of 12 participants. RESULTS/ANTICIPATED RESULTS: For quantitative data, we will test for significant associations between food insecurity, obesity, and selected psychological mechanisms via bivariate correlations and linear and logistic regression models. Qualitative data will be analyzed to identify key themes and concepts that conceptually link the aforementioned psychological mechanisms to food insecurity and obesity. Analyzed qualitative data will be triangulated with quantitative findings. DISCUSSION/SIGNIFICANCE OF IMPACT: This pilot study will examine the role of psychological mechanisms in the relationship between food insecurity and obesity. Moreover, we are gathering data to identify potentially new intervention targets that will be used to develop intervention strategies aimed at reducing health disparities by effectively promoting weight management among low socioeconomic populations.

OBJECTIVES/GOALS: To evaluate the clarity of plain-language informed consent forms (ICF) created using a browser-based tool called the ICF Navigator, we solicited feedback from two community review boards (CRB) to ensure the resulting ICF met the informational needs of all potential participants, including those with limited health literacy skills. METHODS/STUDY POPULATION: Community-engaged research highlights the importance of involving community members in the planning and execution of translational research projects. Virtual discussions were held to elicit feedback from two separate CRBs on the understandability of an ICF that was generated using an online, browser-based tool that we designed to aid researchers in the creation of plain-language ICFs. CRBs included representation of diverse communities from across the state of Arkansas, including individuals who may have limited health literacy skills, those with and without prior experience participating in clinical research projects, members living in rural and urban settings, and those whose race or ethnicity have been traditionally underrepresented among clinical research participants. RESULTS/ANTICIPATED RESULTS: CRB feedback was used to inform actionable improvements to the tool, such as removing content redundancies and embedding tips to guide researchers on how best to optimize the clarity and understandability of resulting ICFs. Program refinements in response to the feedback have been implemented and will be evaluated in another round of CRB discussions in early 2023. Feedback from this follow-up CRB session will also be presented in addition to a discussion of how the feedback was used to improve the online tool, which will ultimately be available for free use by other institutions. DISCUSSION/SIGNIFICANCE: The use of community feedback to optimize the functionality of the ICF Navigator demonstrates the value of CRBs for ensuring that ICFs are culturally salient and readily understandable by all potential research participants, particularly those who may have limited health literacy skills, thereby promoting more equitable opportunities for all.

OBJECTIVES/SPECIFIC AIMS: Evidence-based guideline-concordant care leads to better outcomes in patients with early stage breast cancer, including survival. However, previous studies of guideline compliance have been limited by small study sample sizes, localized geography, unknown causal factors, and lack of diverse population. We use a national database to assess socio-economic, clinical, and facility factors that impact treatment compliance with evidence-based guidelines from the American Society of Clinical Oncology (ASCO) and the National Comprehensive Cancer Network (NCCN). METHODS/STUDY POPULATION: This is a retrospective cohort study of the National Cancer Data Base Participant User File Breast 2014, which captures ~70%–80% of all newly diagnosed cancer cases in the United States. Female patients who were diagnosed with early stage breast adenocarcinoma (T0, T1, T1A, T1B, 2, 2A, or T2N1) from 2004 to 2014 were eligible for this study. RESULTS/ANTICIPATED RESULTS: A total of 807,314 patients were included in this study. Evidence-based guidelines examined with associated compliance rates include surgery completion (79.3% overall compliance), breast conserving surgery Versus mastectomy (88.05% vs. 11.95%, respectively), radiation after breast conserving surgery (77.5% overall compliance), HER2 testing (88.6% overall compliance), estrogen/progesterone receptor (ER/PR) testing (96.3% overall compliance), hormone treatment for positive ER/PR breast cancer (80.2% overall compliance), and sentinel lymph node biopsy completion (67.5% overall compliance). Univariate association between these guidelines and covariates such as facility type, facility location, age, race, insurance status, median income quartiles, achievement of high school degree, urban Versus rural, Charlson-Deyo score, year of diagnosis, and overall survival were assessed. Logistic regression analysis will be used to determine multivariate relationships between these characteristics and the probability that a patient will be compliant to guideline regimen. DISCUSSION/SIGNIFICANCE OF IMPACT: The results of this study will help identify socio-economic, clinical, and facility factors that influence guideline-concordant care and subsequent critical outcomes for patients with early stage breast cancer. Lack of guideline concordant care for specific stages of cancer or treatment modalities will point to a need for tailored interventions to enhance compliance. A prediction model will help identify the most important predictors of noncompliance in breast cancer treatment so noncompliance can be prevented in at-risk populations.

OBJECTIVES/GOALS: The clinical management of differences of sex development (DSDs) aims to guarantee best practices in medical care while addressing concerns related to non-reversible surgeries. Rhetorical analysis was conducted to study the balance between science policy and patient advocacy related to DSD surgeries as depicted in medical education materials METHODS/STUDY POPULATION: Unrestricted transcripts of two educational videos and text from all chapters of a handbook addressed to medical learners and faculty by the Association of American Medical Colleges (AAMC) were submitted to automated word cloud analysis (NVivo, QSR International®). Words with a weighted percentage > 0.19% from total words of a given source were defined as words of frequent use and were selected for further analysis after exclusion of words as conjunctions, prepositions, pronouns, or conversational fillers. Words sharing noun, adjective and adverb forms were coded and weighed as a single word following the Oxford dictionary. Discrepancies on word selection, exclusion or coding were resolved between four raters. The rhetorical context of most frequent words was identified. RESULTS/ANTICIPATED RESULTS: The word cloud analysis of the video resource intended for medical learners (n=104 words of frequent use) and the video intended for medical faculty (n= 94 words of frequent use) depicts a patient-centered approach (word people’) that is based on expert opinion (word [I] think’). The handbook (n= 998 words of frequent use) makes reiterated reference to patients’; lgbt’; gender’; health’; and caring’ while underscoring health concerns that are unrelated to genital variance (health’; caring’ and medical’). The noun surgery’ did not figure among the most frequent words in spoken language nor in written text even when summing its adjective and adverb forms. DISCUSSION/SIGNIFICANCE: Educational materials by the AAMC on DSDs accentuate patient-centered care within a medical humanism framework. However, the lack of discussion of DSD surgeries is an educational gap that should be addressed by key science policy and patient advocacy stakeholders.

OBJECTIVES/GOALS: Autism spectrum disorder (ASD) is characterized by difficulties in communication and social interaction as well as restricted and repetitive behaviors. Sleep problems are a common concern in children with ASD that can persist into adulthood. This study aims to further explore sleep in ASD without intellectual disability (ASD w/o ID). METHODS/STUDY POPULATION: We recruited individuals of both sexes with ASD w/o ID (probands) and relatives as part of the Autism Spectrum Program of Excellence (ASPE) at the University of Pennsylvania. Actimetry data were collected via a wrist-worn tri-axial accelerometer for 21 days. Data from 212 participants were considered. We analyzed sleep data using the algorithms GGIR, ChronoSapiens, and PennZzz. The sleep traits of proband and sibling pairs were compared using paired t-test or Wilcoxon signed-rank test. We used the Social Responsiveness Scale, Second Edition (SRS-2) to assess social impairment and restricted/repetitive traits. We compared SRS-2 scores to sleep traits using partial Spearman or Pearson correlations adjusting for age (171 participants). RESULTS/ANTICIPATED RESULTS: Probands demonstrated later sleep onset (p = 0.03), decreased M10 average (10-hour period of highest activity/day; p = 0.006), decreased relative amplitude (measure of rest-activity rhythm; p <0.001), and decreased total daytime activity (p = 0.005) compared to siblings. Regarding social function and restricted/repetitive traits, adult males showed an inverse correlation between SRS-2 total score and sleep efficiency (r = −0.2, p = 0.04) and a positive correlation between SRS-2 total score and intradaily variability (r = 0.3, p = 0.02). Adult females showed an inverse correlation between SRS-2 total score and M10 average (r = −0.3, p = 0.02) and between SRS-2 total score and relative amplitude (self-report r = −0.4, p = 0.001; informant r = −0.3, p = 0.005). DISCUSSION/SIGNIFICANCE OF IMPACT: This study focuses on the analysis of sleep traits in ASD including the relationship between social function and sleep. Thus far, the most robust findings are decreased daytime activity and relative amplitude in individuals with ASD w/o ID compared to siblings. We have also shown that ASD social impairment may be related to sleep dysfunction.

OBJECTIVES/SPECIFIC AIMS: Program Directors and Ph.D. students within the Clinical and Translational Science (CTS) track identified mentorship development as a knowledge gap and educational priority. Most mentors are not provided education in how to be an effective mentor. Similarly, most mentees are not provided education or training on how to optimize a mentoring relationship for their learning and professional development (Ramani, 2006). We adapted mentor training curriculum developed by the University of Wisconsin and facilitated an eight-hour program to better prepare learners to be empowered mentees as well as future mentors. METHODS/STUDY POPULATION: We utilized the Mentoring Competency Assessment (MCA) to measure CTS Ph.D. students’ self-perceptions of eight competencies through a pre and post-intervention survey design (Fleming, etal., 2013). We adapted an evidence-based curriculum (Pfund, etal., 2014) to be delivered to Ph.D. students within an existing structure of educational offerings and incorporated case based discussions, frequent low-stakes formative assessments, and peer-to-peer facilitation to heighten authenticity, relevance and immediacy to the learning experiences. This structured curriculum, intended to increase skills, knowledge, and behaviors to make students more active participants in their mentoring relationships, focuses on one competency area per monthly session and was implemented May-December 2018. Session participation by program alumni allows for contextual demonstration and competency application. RESULTS/ANTICIPATED RESULTS: Preliminary data demonstrates heightened perceived competency in most domains assessed. We found mentors generally rated their mentee’s skills at a higher level than the mentees’ perceived ratings. We also saw significant differences between groups in a few domains e. g. new vs. established relationships, females vs. males, etc. Individual session evaluations are extremely positive, and the students routinely report behavioral changes as a result of these sessions. DISCUSSION/SIGNIFICANCE OF IMPACT: We have demonstrated the successful adaptation and innovative facilitation of a successful mentorship development program for Ph.D. students. We propose that several factors discussed are critical in the success of this type of curriculum. Preliminary conclusion: A structured curriculum in mentoring relationships increases Ph.D. mentee empowerment and readiness to lead future mentoring relationships.

ABSTRACT IMPACT: Patients living in overcrowded zip codes were at increased risk of contracting severe COVID-19 after controlling for confounding disease and socioeconomic factors OBJECTIVES/GOALS: This study sought to examine whether residences in over-crowded zip codes with higher reported over-crowding represented an independent risk factor for severe COVID-19 infection, defined by presentation to an emergency department. METHODS/STUDY POPULATION: In this zip code tabulated area (ZCTA)-level analysis, we used NYC Department of Health disease surveillance data in March 2020 merged with data from the CDC and ACS to model suspected COVID-19 case rates by zip code over-crowdedness (households with greater than 1 occupant per room, in quartiles). We defined suspected COVID-19 cases as emergency department reported cases of pneumonia and influenza-like illness. Our final model employed a multivariate Poisson regression models with controls for known COVID-19 clinical (prevalence of obesity, coronary artery disease, and smoking) and related socioeconomic risk factors (percentage below federal poverty line, median income by zip-code, percentage White, and proportion of multigenerational households) after accounting for multicollinearity. RESULTS/ANTICIPATED RESULTS: Our analysis examined 39,923 suspected COVID-19 cases across 173 ZCTAs in NYC between March 1 and March 30 2020. We found that, after adjusted analysis, for every quartile increase in defined over-crowdedness, case rates increased by 32.8% (95% CI: 22.7%% to 34.0%, P < 0.001). DISCUSSION/SIGNIFICANCE OF FINDINGS: Over-crowdedness by zip code may be an independent risk factor for severe COVID-19. Social distancing measures such as school closures that increase house-bound populations may inadvertently worsen the risk of COVID-19 contraction in this setting.
