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.

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/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: 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/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.

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/GOALS: This presentation reports activities of a NCATS-funded collaborative working group created to promote dissemination and implementation (D&I) research within the CTSA landscape. Our working group seeks to meet both the conceptual as well as practical challenges to advancing the utilization of D&I across the translational science spectrum. METHODS/STUDY POPULATION: A fundamental focus of D&I is supporting the movement of effective health interventions into real-world use so that they benefit population health. Yet, this process remains unpredictable, with some interventions receiving widespread uptake in practice and others (of similar potential benefit) failing to translate. The value of research efforts is wasted when directed toward the “wrong” interventions. Recent discussion and experience amongst investigators in our collaborative working group has resulted in new ways of addressing this problem. Specifically, tools borrowed from business and management have shown promise in predicting which health interventions have the highest potential for commercialization and dissemination. RESULTS/ANTICIPATED RESULTS: We will conduct an environmental scan of CTSA hubs to understand their approaches to supporting commercialization and business development around research products, identifying the most promising and effective methods and processes. We will compile various tools for identifying and supporting interventions with the highest potential for commercialization, including how to form the multidisciplinary and stakeholder-engaged teams necessary to make these determinations. Finally, we will further explore the differences between patentable and non-patentable innovations and make recommendations for CTSAs in supporting the latter. DISCUSSION/SIGNIFICANCE: Commercialization of non-patentable interventions is an essential and underexplored element of the translational science spectrum. The perspectives and methods of D&I should not be relegated to late-stage translational steps, but rather inform the conduct of translational science writ large.

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.

OBJECTIVES/GOALS: To examine i) how longstanding (≥6 years) community-based participatory research (CBPR) partnerships nationwide implemented a validated questionnaire to measure success and its contributing factors and ii) how the CBPR partnerships utilized and applied a feedback mechanism, or reports of findings from the questionnaire and a facilitation guide METHODS/STUDY POPULATION: This mixed methods study builds upon a larger NIH-funded project entitled ’Measurement Approaches to Partnership Success (MAPS). MAPS developed and validated the 109-item MAPS questionnaire to measure success in longstanding (≥6 years) CBPR partnerships. In 2020, 55 CBPR partnerships nationwide completed the MAPS Questionnaire and, a year later, received the MAPS Feedback Mechanism, consisting of questionnaire findings and a facilitation guide on how to present the findings. In this follow-up study, we administered multi-method surveys to each partnership contact person in 2022 to examine their experience with and utility of the MAPS Questionnaire and the MAPS Feedback mechanism. We performed descriptive analysis of quantitative responses using SAS and thematic analysis of qualitative responses. RESULTS/ANTICIPATED RESULTS: Survey responses have been presently collected from 14 partnerships. Preliminary findings suggest that the most frequently reported benefits of completing the MAPS Questionnaire included stimulating partnership reflections and ease of completion. Many partnerships shared results of the MAPS Questionnaire by e-mail or during partnership meetings. Nearly half of the partnerships rated components of the MAPS feedback mechanism as useful. Over one-third of the partnerships reported that the COVID pandemic limited their capacity to engage with the MAPS Feedback Mechanism. Key qualitative suggestions included making the MAPS Questionnaire shorter, providing it in a different format, and offering additional facilitation to support the implementation of the MAPS Feedback Mechanism. DISCUSSION/SIGNIFICANCE: This study examines how CBPR partnerships utilize an evaluation instrument and apply results on success. Current findings suggest potential utility of the MAPS Questionnaire and Feedback Mechanism for ongoing evaluation. Reducing the questionnaire length and providing facilitation resources may enhance implementation across diverse settings.

OBJECTIVES/SPECIFIC AIMS: “Loss to follow up” is a common phenomenon and challenge in clinical medicine. Missed appointments are a well-documented source of waste in the health care system, and can lead to strained patient-physician relationships and inferior quality of care. Meningiomas are relatively common, benign tumors that arise from the dural coverings of the brain. Although complete surgical resection is considered curative, surgically excised meningiomas have a well-documented propensity to recur, necessitating continued imaging surveillance of postresection patients. A recent retrospective study at our institute demonstrated that 20% of postresection patients fail to return for follow up within a year of their surgery. Although social determinants of health have been associated with failure to follow up in this population, there has been no research identifying patient-reported barriers that result in loss to follow up in this patient population. The purpose of this study is to identify specific barriers that prevent patients from returning for surveillance. METHODS/STUDY POPULATION: We used an IRB approved, prospective brain tumor clinical database to identify patients who underwent surgical resection of intracranial meningioma at our institution between 2001 and 2013. “Loss to follow up” was defined as failure to attend follow-up appointments with neurosurgery, radiation oncology, or neuro-oncology within a year of the most recent assigned follow-up interval, as recorded in the electronic medical record. Structured interviews were conducted with patients who met study criteria and specific barriers to follow-up were elicited, transcribed, and coded. In 2 cases, a primary caregiver participated in all or portions of the interview with the patient. A general assessment of patient knowledge about meningioma and a screening for basic health literacy were also conducted. RESULTS/ANTICIPATED RESULTS: There were 80 patients in the brain tumor clinical database met chart review criteria for inclusion in the study. A total of 9 structured interviews were conducted; 1 interview was excluded from analysis for failure to meet study criteria. In total, 24 unique obstacles to follow up were recorded. These were stratified and grouped into 4 broad categories: 2 of 8 (25%) patients identified environmental factors, including distance to appointment and challenges with insurance coverage as barriers to follow up; 2 patients (25%) identified psychosocial factors, including poor communication with and distrust of their neurosurgeon as barriers to follow up; 2 (25%) patients identified health factors, including poor health and old age, as barriers to follow up; 6 patients identified healthcare systems factors as barriers to follow up, with 6 patients (75%) reporting seeing a non-specialist for follow up after surgery and 4 patients (50%) reporting not being told by their neurosurgeon that they would need continued follow up. Of those patients seen by non-specialists, only 1 reported any recent brain imaging by those providers. All patients had limited to no prior knowledge of meningiomas before their diagnosis. Four (50%) patients reported satisfaction with the level education about meningiomas they received from their physician. Of these patients, 3 (75%) correctly reported that meningiomas may recur following surgery. Of the patients who did not report satisfaction with physician counseling, 3 (75%) did not realize that meningiomas can recur. DISCUSSION/SIGNIFICANCE OF IMPACT: Healthcare system factors, including uncoordinated transition of postoperative care to non-neurosurgeons and uncertain postoperative surveillance schedules, represent that most common patient-identified barriers to follow up after meningioma resection. Improving transition of care from specialists to non-specialists, including designation of appropriate imaging surveillance schedules, as well as improving communication between specialists and patients about the need for continued follow up, represent clear points for intervention that could improve care for this patient population. In addition, consistent and clear counseling about meningioma and its disease course may reduce loss to follow up following meningioma resection. It is important to note, however, that the small sample size represents a significant limitation of the study.

Objectives/Goals: Electronic health record (EHR)-based recruitment can facilitate participation in clinical trials, but is not a panacea to trial accrual challenges. We conducted a root cause analysis to identify EHR-based accrual barriers and facilitators in a pragmatic randomized trial of metformin for those with prostate cancer and glucose intolerance. Methods/Study Population: We quantitatively analyzed enrollment drop-offs among eligible patients who either did not complete a consent (with analysis of EHR-embedded consent process) or who completed a consent but were not enrolled (with analysis of EHR implementation of a Best Practice Alert). We summarized data from the EHR by eligibility, provider encounters, and alerts, and generated CONSORT diagrams and tables to trace the enrollment pathway. We supplemented quantitative findings with a thematic analysis of semi-structured individual interviews with eligible patients (n = 10) and study providers (n = 4) to identify systematic barriers to recruitment and enrollment of eligible patients. Results/Anticipated Results: CONSORT diagram analysis found that 24% of potentially eligible patients (268 of 1130) had an eligible study encounter but were not enrolled. Additionally, BPAs were not triggering for some eligible patients. Interviews revealed that study providers wanted more detailed information about which study arm their patient would be assigned to, and about next steps after enrollment, especially relating to additional lab tests and follow-up care needed. Patient interviews suggested that patients often did not remember completing the consent process and felt overwhelmed with appointments and information; patients expected providers to actively bring up research opportunities during appointments. Discussion/Significance of Impact: While pragmatic EHR-embedded trials are often characterized as lower-burden, these trials still require active engagement by providers, as well as ongoing attention from both research and informatics teams to ensure that EHR-embedded processes are functioning as designed, and that they are effective in recruiting study participants.

OBJECTIVES/SPECIFIC AIMS: Diet-related diseases such as obesity, hypertension, diabetes, and irritable bowel syndrome comprise a large portion of primary care visits in the United States. However, primary care physicians seldom prescribe dietary interventions that effectively treat these conditions, and their rate of use has declined in recent years. There are many plausible reasons for this decline, including baseline nutrition education, perceived efficacy of the intervention, time limitations, and compensation. No study has been conducted to assess which of these factors physicians perceive as relevant to their decision to use dietary interventions in their practice. Our study aims to identify key factors that ubiquitously limit physicians’ use of dietary interventions. METHODS/STUDY POPULATION: We created a 30-item survey designed to evaluate physicians’ self-reported use of dietary interventions, relevant knowledge base, comfort employing these interventions, and attitudes regarding the importance of such interventions in their practices. This survey was was distributed to internal medicine, pediatrics, and family medicine residents and physicians at Michigan Medicine and St. Joseph hospitals in Ann Arbor, MI. RESULTS/ANTICIPATED RESULTS: Socio-demographic data, knowledge base and attitudes will be summarized and analyzed using descriptive statistics and simple regression modeling following the administration of the survey. DISCUSSION/SIGNIFICANCE OF IMPACT: We hope that our study may elucidate identify specific avenues of increasing the use of dietary interventions, and thus of improving treatment efficacy for diet-related disorders in the United States.

OBJECTIVES/GOALS: Partnering with the Housing Authority of Los Angeles, we launched a place-based initiative in the Nickerson Gardens housing development in South Los Angeles, where we apply our community engagement approach of listening and learning, and trust and relationship building, to deliver public health interventions in a discrete community. METHODS/STUDY POPULATION: Nickerson Gardens is the largest housing development in Los Angeles, with 1,066 units and over 3,000 residents. 58% and 40% of the residents are Hispanic and Black/African American respectively with an average yearly income of less than $30,000. To build trust and establish relationships, our team began attending community events, holding weekly educational workshops, and participating in the summer program for youth. We also held listening sessions in English and Spanish that asked aboutthe overall health of the Nickerson Gardens community, environment and public space, access and barriers to care, needed healthcare services, and the lived experience within Nickerson Gardens. RESULTS/ANTICIPATED RESULTS: To date, we have held eight 90-minute listening sessions in English and Spanish with 59 participants. The sessions provided insight into theneeded health and educational resources and services, the organizational structure of the housing development and how that impacts access to information and services, as well as the nuanced and area-specific transportation issues and the connection to safety concerns. These findings will inform the next phase of this initiative which includes convening a Coordinating Council composed of service providers and Nickerson Gardens residents. This council will oversee the coordination and implementation of needed services, help maintain accountability of the providers, and offer residents the opportunity to take ownership of the process. DISCUSSION/SIGNIFICANCE: Academic-community partnerships are an effective strategy to deliver public health interventions and promote health equity in under-resourced communities. We tested and measured impact in a distinct community to reinforce a widely-applicable place-based model.

OBJECTIVES/GOALS: The goals of this evaluation were 1) to describe the pilot grant application cycle and processes at NC TraCS, 2) to illustrate the impact of pilot grants on extramural grant funding, and 3) to provide a framework for other institutions to utilize for the evaluation of pilot grant programs. METHODS/STUDY POPULATION: From 2009-2019 the NC TraCS pilot program funded 925 projects, varying from $2,000 to $100,000. Pilot grants are available to any researcher affiliated with the university as well as partner institutions and community stakeholders. For this evaluation we analyzed data on pilot applicants (demographics, type of pilot, funding status, resubmissions, etc.) and outcomes (extramural funding, publications, etc.) yielded from funded pilots. In addition to summary statistics, we also calculated return on investment (ROI) for the program as a whole and by specific grant type. We will use bibliometric network analysis to assess productivity, citation impact, and scope of collaboration. RESULTS/ANTICIPATED RESULTS: There have been 2,777 submitted proposals with an acceptance rate of 33.3%. Unfunded proposals can resubmit, 61.8% of resubmitted applications are successfully funded, and 29.6% of funded applications are resubmissions. The $2,000 awards accounted for 43.4% of all grants awarded but only accounted for 6.4% of all pilot funds awarded. Success of proposals was proportional to the number of applications from each academic unit. 60.8% of funded applicants were affiliated with the School of Medicine and account for 65.3% of all funding awarded from 2009-2019. Additionally, we plan on analyzing return on investment rates to illustrate the impact of pilot awards on future research funding. DISCUSSION/SIGNIFICANCE OF IMPACT: Pilot grants can lead to subsequent extramural grants, publications, and successful translation of research into practice. This evaluation will assist our institution in understanding the impact of pilot grants and will provide a road map for other institutions evaluating their own programs.

Objectives/Goals: Posttraumatic stress disorder (PTSD) is common during pregnancy and postpartum, leading to adverse birth outcomes. Despite effective interventions like narrative exposure therapy, PTSD often goes untreated due limited training opportunities and lack of community support. Expanding training for PTSD is crucial to improving access to care. Methods/Study Population: Six 3-day PNET trainings were delivered to 57 participants over a 23-month period. Workshop attendees represented a variety of professions (19% Social Workers, 19% Mental Health Graduate Trainees, 18% Psychologists, 18% Counselors, 12% Doulas, 11% Physicians, and 5% Home Visitor/Parent Educators) with varying levels of specialty experience from diverse locations (2 countries and 13 states). Key workshop outcomes included participant one-week post-workshop satisfaction, perceptions of acceptability, appropriateness, and feasibility of the intervention, and pre- to one-week post-workshop perceptions of connectedness to trauma treatment and perinatal healthcare communities. Data will be explored at 6 months post-workshop to evaluate longer-term effects on connectedness. Results/Anticipated Results: The majority of workshop attendees (84%, M =  4.76, range 1–5) reported being “extremely satisfied” with the training and 98% indicated they would “recommend it to others.” Most attendees found NET to be acceptable (M  =  4.64, range  =  1–5), appropriate (M  =  4.37, range  =  1–5), and feasible (M  =  4.49, range  =  1–5) to use within their practice. Paired t-tests revealed a significant increase in a sense of connectedness to both the trauma treatment and perinatal healthcare communities from pre- to post-workshop. Discussion/Significance of Impact: Findings indicate that the PNET workshop is feasible and effective in training interdisciplinary providers on perinatal PTSD evidence-based interventions. By training a range of professionals and fostering a sense of connectedness, the PNET workshop has the potential to make effective trauma treatments accessible to underserved populations.

OBJECTIVES/GOALS: The Institute of Translational Health Science (ITHS) Remote Technologies for Research Reference Center (REMOTECH) aims to support researchers using remote technologies. Understanding barriers specifically for engagement of diverse populations is critical to improve equitable access and increase diverse participation in research. METHODS/STUDY POPULATION: We conducted semi-structured interviews with researchers (N=30) within the WWAMI (Washington, Wyoming, Alaska, Montana and Idaho) region, identified through participation in a previous survey as well as those known to have previously implemented remote technologies at ITHS institutions. We solicited specific concerns regarding equity, diversity, and inclusion (EDI) related to remote research participant recruitment, retention, and implementation, as well as outcomes and potential solutions. Interview transcripts were coded, summarized, and emerging themes were identified. RESULTS/ANTICIPATED RESULTS: The pandemic necessitated a shift to the use of remote research engagement strategies. Our interview findings show that researchers have a desire to: increase diversity through remote engagement options; decrease participant burden; and understand and include strategies that advance equity, diversity, and inclusion (EDI) efforts. While geographic diversity was positively impacted by the use of remote technologies, significant barriers and challenges currently exist in the use of remote technologies with respect to other types of diversity, for example access to technologies and limited financial resources. DISCUSSION/SIGNIFICANCE: Remote technologies in research could increase diversity, but interviewees shared barriers and challenges that prevent that from happening. Researchers would benefit from equity-oriented digital literacy resources to use with diverse populations. Such tools can also be used to guide study design/procedures, materials, and processes.
