OBJECTIVES/GOALS: A major barrier to older adult (65+) over-the-counter (OTC) safety is the lack of actionable research on factors affecting older adult decisions during OTC selection. This goal of this study is to develop and validate a survey instrument based on the Protection Motivation Theory to measure older adults perceived risk of OTCs. METHODS/STUDY POPULATION: The 24-item OTC Protection Motivation survey underwent revision using a consult from the UW Survey Center as well as rigorous cognitive interviewing and pilot testing with 8 older adults. It was administered to 103 community-dwelling older adults. OTC misuse data was gathered from 15 of the participants. OTC misuse evaluated by three pharmacy experts on the basis of OTC appropriateness given participants age, existing conditions, concurrent medication use, and intention to adhere to label guidelines. Multivariate linear regression was used to examine the relationship between OTC misuse and protection motivation. Exploratory factor analysis (EFA) was used to determine a model of best fit to describe the factor structure of the OTC Protection Motivation survey. RESULTS/ANTICIPATED RESULTS: The EFA yielded a 5-factor model of protection motivation, which included the components of deliberative risk perception, a combination of experiential and affective risk perception, threat severity, protective behavior intent, and perceived efficacy in protective behavior engagement. The EFA-based item reduction resulted in a final 18-item OTC Protection Motivation survey. DISCUSSION/SIGNIFICANCE: Older adults, who have the lowest health literacy levels, are responsible for 30% of OTC medication use and 61.5% of emergency department visits due to adverse drug events. This study is the first to characterize the relationship of OTC protection motivation and OTC misuse to inform patient-centered interventions for older adult OTC safety.

OBJECTIVES/GOALS: The main objectives are to obtain a preliminary profile of the adult Puerto Rican patient with hearing impairment and to identify the factors, variables and barriers that thess patients face accessing intervention and adscribing to it. METHODS/STUDY POPULATION: Adults between the ages of 21 and 64 years old were surveyed using a questionnaire with items guided to obtain information regarding their socio-demographic and health characteristics and the variables associated to treatment access and adherence to the intervention plan. A descriptive approach will be used to create the sample profile and an age stratified analysis will be used to interpret the empirical data. The identified variables associated to treatment access and adherence will be identified and analyzed to study if there is a possible geographic zone and socio-economical association. RESULTS/ANTICIPATED RESULTS: Preliminary results suggest that regardless of the subject’s age and degree of hearing loss their socio-economical strata is a decisive factor in treatment adherence as well as the lack of medical insurance coverage for therapy, hearing prosthesis and assistive technology for the hearing-impaired. Access to service was found to be a barrier associated to the subjecs geographical place of origin. DISCUSSION/SIGNIFICANCE: Research findings suggest that there is an association between the socio-economical status of the Puerto Rican hearing impaired patient, the lack of medical coverage and the level of treatment adherence. Patients from a lower socio-economical status and remote towns exhibited less adherence which points to a health disparity for this population.

OBJECTIVES/GOALS: Roughly 8% of children in the United States have a diagnosed food allergy (FA). The ubiquity of most food allergens increases the potential for accidental exposures. Clinical trials (CT) are used to test novel treatments for FA. This project will evaluate the influence of biopsychosocial factors on interest in CT participation for pediatric FA. METHODS/STUDY POPULATION: This project is subsumed under the FORWARD study (5R01AI130348-04), a multisite study currently underway at four pediatric FA clinics across the United States. Eligible participants include patients and families who meet the following criteria: 1) New clinic visit presenting for a possible FA complaint and/or has a physician diagnosis in a follow-up clinic visit; 2) child is between the age of 6-months and 12 years at intake visit; 3) are English speaking, and 4) no history of developmental disorders. Parents are asked to complete an intake survey, followed by a series of quarterly surveys administered via REDCap. A single variable from the intake survey queries interest in CT participation; quarterly surveys assess FA knowledge, attitudes, health beliefs, and management practices. RESULTS/ANTICIPATED RESULTS: To date, 890 families have completed the intake survey. Working hypotheses include: 1) parents of older children and children with a higher condition severity rating will report greater levels of interest in CT participation; 2) parents with greater FA knowledge, more health management beliefs that support action, and less FA-related anxiety, will report greater levels of interest in CT participation; 3) relative to White families, African American families will be less interested in participating; 4) families with >1 child with FA will report greater levels of interest in CT participation; 5) families who are uninsured, low-SES, and are unemployed will report lower levels of interest in CT participation; and 6) families with higher educational attainment will report lower levels of interest in CT participation. DISCUSSION/SIGNIFICANCE: This study will advance decision science, address existing disparities, and have far-reaching clinical implications. This novel approach will enhance our ability to predict who is at the greatest risk of anaphylaxis and help healthcare providers identify families who could benefit from experimental treatment options for pediatric FA.

OBJECTIVES/GOALS: Determine if exposure to violence at different life stages (childhood versus recent exposure) in postpartum women is associated to increased risk of weight retention more than 1 year and no more than 2 years after delivery, thus increasing health risk in short and long term. METHODS/STUDY POPULATION: Participants will be recruited from a cohort of post-partum women who received services from the Puerto Rico Women and Children Program (PR WIC) during pregnancy and postpartum period as per PR WIC established criteria. Families that have completed their participation in a Lifestyle intervention trial will be paired 2:1 with eligible nonparticipants that fulfill trial enrollment criteria. Language, culture validated instruments will be used to document maternal violence exposure in childhood and recent exposure, defined as within the last 12 months. To asses weight retention, pre-pregnancy weight will be compared to actual weight at the moment of evaluation, anthropometric measurements (weight, length, body composition, and fat mass) will be used to determine the health risk category for each participant. RESULTS/ANTICIPATED RESULTS: Expected results will be that there is an association between violence exposure and weight retention among post-partum women, thus influencing their weight status. The use of the questionnaires as screening tool for history of violence and whether recent or childhood exposure should be considered a health risk during pregnancy and post-partum predisposing women to adipose tissue related disorders. DISCUSSION/SIGNIFICANCE: Findings will reinforce the importance of integrated screening and proactive management of social determinants of health within clinical and social services that target this population. Also, contribute to the development of strategies tailored to break violence cycle as a public health measure.

OBJECTIVES/GOALS: Since 2013, managers of community engagement (CE) programs across the Clinical and Translational Science Award (CTSA) consortium funded by the National Center for Advancing Translational Sciences (NCATS) have convened monthly to build connections, share knowledge, and enable collaboration. METHODS/STUDY POPULATION: Notable for focus on staff leadership, the CE Brokers group has been central to the ongoing success of CTSA community engagement partnerships and approaches to research. In early 2022, a survey of the 139-member group asked about their roles and responsibilities, the ways the CE Brokers network has contributed to their hubs adoption and development of best practices and innovations, resources and lessons learned, and the creation of opportunities for members to collaboratively conduct and disseminate original research, and research on the science of community engagement. The survey also asked CE Brokers if they or their community partners are part of an underrepresented community. RESULTS/ANTICIPATED RESULTS: These demographic data will be shared, along with analyses of data on growth of the group over time, evolving themes, and a SWOT analysis completed in 2021. DISCUSSION/SIGNIFICANCE: This will provide a platform to explore new avenues for the CE Brokers and their impact within the NCATS CTSA consortium, in line with the evolving direction of the clinical and translational research enterprise.

OBJECTIVES/GOALS: COVID-19 has taken a big toll on health, mental health and community well-being. COVID-19 has also presented unique opportunities for community engagement programs to sustain their work within communities. Low-tech methods of engagement might provide opportunities for success. METHODS/STUDY POPULATION: When we could not be in the field due to COVID-19, we recontacted our 12.4k HealthStreet members by phone and in 12 months successfully contacted 3.2k. By contrast, over the two COVID affected years (2019 & 2020), our in-person recruitment efforts in the community fell to 832 from 1817 in the two prior years (2017 & 2018). Reconnecting with existing members is an important aspect of sustainable community engagement. RESULTS/ANTICIPATED RESULTS: While 8/10 of the 3.2 K sample had internet access in their homes, 9/10 said having it was somewhat to very important. Importantly, 1 in 3 people who had additional needs or suggestions were looking for better COVID-19 knowledge or ways to reduce the threat of illness, 1 in 4 wanted resources; and 1 in 5 encouraged us to keep doing what we were doing. Among recontacted members, 30.2% indicated a high stress level (8 & over on a 10 point scale) while 15.2% reported a high level of loneliness (8 & over on a 10 point scale). High stress was significantly more likely among those identifying as African American (23.1%) compared to non-African American (16.6%). Loneliness did not vary (10.1% among both). DISCUSSION/SIGNIFICANCE: Sustainable community engagement was important to reach community members during the pandemic, especially given the high rates of stress and loneliness among members contacted. In-person connections were reduced, but phone contact provided an opportunity for successful engagement.

OBJECTIVES/GOALS: The prevalence of patients with end-stage kidney disease (ESKD) in PR has increased in the last decade along with an aging population, while waitlisted patients have decreased. Our objective is to compare clinical and sociodemographic characteristics of patients with ESKD on dialysis who are waitlisted from those who are not waitlisted. METHODS/STUDY POPULATION: Retrospective study of all patients with ESKD who received dialysis in PR from 2013-2019, based on the United States Renal Data System data. Variables: (1)waitlisting status (yes or no; waitlisting date); (2)sociodemographics (age at dialysis initiation, sex, zip-code area, health insurance type, and employment status); and (3)clinical characteristics (dialysis initiation date, primary diagnosis of renal disease, comorbidities including obesity, diabetes, peripherovascular/cardiovascular disease, cancer, etc.). Statistics: (1)descriptive statistics (continuous - central tendency [mean, median] and dispersion [standard deviation, interquartile range]; and categorical [frequencies and percentages]); (2)Chi-square test, Students t-test, and Mann Whitney U test to evaluate differences. RESULTS/ANTICIPATED RESULTS: We expect patients on dialysis not waitlisted will be older and have more comorbidities than those who are on dialysis and waitlisted. DISCUSSION/SIGNIFICANCE: Kidney transplant is the choice of therapy for ESKD and its benefits are better quality of life, improved survival, and best long term-cost effectiveness. If our hypothesis is true, findings will highlight the importance of characterizing which patients with ESKD on dialysis are kidney transplant candidates when considering barriers to waitlisting.

OBJECTIVES/GOALS: Our research has three main aims: 1. Measure attitudes toward a SARS-CoV-2 vaccine among BIPOC. 2. Assess the effectiveness of race-conscious public health messages in changing attitudes toward a SARS-CoV-2 vaccine. 3. Test the efficacy of financial incentives to increase uptake of a SARS-CoV-2 vaccine. METHODS/STUDY POPULATION: We surveyed 784 unvaccinated residents of L.A. County. To recruit participants, we collaborated with Qualtrics. The survey randomized participants to one of three public health messages, as well as one of two financial compensation schemes. Twenty-five participants completed semi-structured interviews via Zoom or telephone. Interviews were audio recorded, translated into English if needed, and transcribed. The inductive, semi-structured interview guide focused on three domains: i) concerns and distrust toward a COVID vaccine, ii) policy interventions and/or government action related to a COVID vaccine, iii) non-pharmacological policy interventions related to the COVID-19 pandemic. Major emergent themes were identified and analyzed using Watkins (2012) team analysis of qualitative data steps. RESULTS/ANTICIPATED RESULTS: Many BIPOC remain vaccine hesitant: 2/3 of the survey respondents stated that they did not intend to or were not sure if they planned to get vaccinated. Follow-up interviews show that fear of vaccine side effects, bodily autonomy in choosing to get vaccinated are major concerns. However, public health measures like masking and physical distancing remain preferred safety methods for BIPOC residents. Misinformation and overcommunication in public health messaging concerning vaccine eligibility may be a major barrier to vaccine uptake among BIPOC. DISCUSSION/SIGNIFICANCE: Real world financial compensation mechanisms need to provide large enough compensation to avoid a crowding out of altruistic vaccination motivations and to effectively incentivize increased vaccine uptake. Additionally, short race-conscious public health messages were ineffective at improving vaccine attitudes.

OBJECTIVES/GOALS: Health insurance status is associated with differences in access to healthcare and health outcomes. The objective of this study was to test the hypothesis that among infants born in the United States, maternal private insurance compared with public Medicaid insurance would be associated with a lower infant mortality rate (IMR). METHODS/STUDY POPULATION: This ecological study used data from the Center for Disease Control and Prevention (CDC) WONDER expanded linked birth and infant death records database 2017-2018. We included hospital-born infants from 20 to 42 weeks of gestational age (wga) if the mother had either private or Medicaid insurance. We excluded infants with congenital anomalies and infants who died due to congenital anomalies. We used negative-binomial regression adjusted for race, sex, multiple birth, and any maternal pregnancy risk factors (as defined by the CDC) to determine the difference in IMR between private and Medicaid insurance. Chi-square or Fishers exact test was used to compare differences in categorical variables between groups. RESULTS/ANTICIPATED RESULTS: We included 6,901,328 infants; 53.6% had private insurance and 46.4% were insured by Medicaid. Privately insured infants had a lower IMR compared with Medicaid insured infants (2.84/1000 vs. 5.32/1000; adjusted relative risk (aRR) 0.71; 95% confidence intervals (CI) 0.62 to 0.81; p<.0001). The privately insured had higher rates of 1st trimester prenatal care compared to those with Medicaid (85.6% vs. 66.6%; p<.00001). Rates of infant morbidity and maternal morbidity (per CDC definitions) were lower among the privately insured compared to those with Medicaid (both p<.00001). The privately insured had lower rates of preterm (9.1% vs. 11.0%), extremely preterm (0.5% vs. 0.7%), low birth weight (7.1% vs. 9.6%), and extremely low birth weight (0.5% vs. 0.7%) births compared to those with Medicaid (all p<0.001). DISCUSSION/SIGNIFICANCE: Private insurance is associated with a lower IMR compared to Medicaid insurance. Privately insured pregnancies also have higher rates of early prenatal care, less morbidity, and less preterm and low birth weight births. There may be opportunities to improve access to care and pregnancy outcomes among Medicaid insured pregnancies in the United States.

OBJECTIVES/GOALS: The Penn State CTSI has been working diligently to help communities in their fight against COVID-19. As the rapidly evolving COVID-19 situation has unfolded the Penn State CTSI has been able to provide support to our community stakeholders. As our communities have and are faced with unprecedented challenges, our CTSI has been there every step of the way. METHODS/STUDY POPULATION: The Penn State CTSI is unique as it sits in rural Pennsylvania that not only spans a wide catchment area but also many diverse communities. The Penn State CTSI connected with our communities throughout the pandemic to bring timely and culturally appropriate information about the novel COVID-19 pandemic through our own institution and in partnership with community leaders. Stakeholder boards were formed to hear from various communities about hardships and challenges that were and are being faced due to COVID-19. RESULTS/ANTICIPATED RESULTS: The Penn State CTSI provided our communities with information through various different platforms to ensure that needs were being met in dissemination of pertinent information related to COVID-19. No only was information tailored to the specific needs that were discussed during stakeholder boards, the information was provided in different languages and platforms in order to meet cultural and other needs to ensure health equity and literacy were met. DISCUSSION/SIGNIFICANCE: Not only did the Penn State CTSI provide these services to our current community partners new partnerships were formed to create stronger alliances amongst those being serve. Members of the Penn State CTSI were invited to serve on state and local advisory bords and became trusted messengers in our communities.

OBJECTIVES/GOALS: Clinical trials of SGLT2 inhibitors in patients with heart failure (HF) have confirmed a reduction in hospitalization and death. Adoption of novel therapeutics has been slower in Black and female patients. We investigated utilization of SGLT2 inhibitor in patients with HF and type 2 diabetes and if there were utilization differences by race or gender. METHODS/STUDY POPULATION: We created a retrospective cohort of outpatients with HF at Emory Healthcare from 2015 to 2020. Additional inclusion criteria included presence of heart failure and a diagnosis of T2D. SGLT2 inhibitor use was identified by a presence of SGLT2 inhibitor prescription at the time of the clinic visit. We estimated differences in prescription of SGLT2 inhibitors by race and gender using Chi-square analysis. RESULTS/ANTICIPATED RESULTS: The cohort included 5829 patients, age 69.47 years ± 13.44, 47.67 % female, 54.62% Black. Overall prescription of SGLT2 inhibitors was low but increased over time (1.4% in 2015 to 5.6% in 2020; p<0.0001). On average, SGLT2 inhibitor use increased annually by 44.77%. From 2015 to 2020, fewer female than male patients were on an SGLT2 inhibitor (1.94% vs. 2.73%, p=0.0033). A similar percentage of Black and non-Black patients were on an SGLT2 inhibitor (2.13% vs. 2.64%, p=0.0591). DISCUSSION/SIGNIFICANCE: Prescription rates of SGLT2 inhibitors remain low in patients with T2D and HF, especially for female patients, despite evidence of their benefit on hospitalizations and mortality. Implementing use of SGLT2 inhibitors in this population represent an opportunity to improve cardiovascular outcomes.

OBJECTIVES/GOALS: Identification of COVID-19 patients at risk for deterioration following discharge from the emergency department (ED) remains a clinical challenge. Our objective was to develop a prediction model that identifies COVID-19 patients at risk for return and hospital admission within 30 days of ED discharge. METHODS/STUDY POPULATION: We performed a retrospective cohort study of discharged adult ED patients (n = 7,529) with SARS-CoV-2 infection from 116 unique hospitals contributing to the national REgistry of suspected COVID-19 in EmeRgency care (RECOVER). The primary outcome was return hospital admission within 30 days. Models were developed using Classification and Regression Tree (CART), Gradient Boosted Machine (GBM), Random Forest (RF), and least absolute shrinkage and selection (LASSO) approaches. RESULTS/ANTICIPATED RESULTS: Among COVID-19 patients discharged from the ED on their index encounter, 571 (7.6%) returned for hospital admission within 30 days. The machine learning (ML) models (GBM, RF,: and LASSO) performed similarly. The RF model yielded a test AUC of 0.74 (95% confidence interval [CI] 0.71–0.78) with a sensitivity of 0.46 (0.39-0.54) and specificity of 0.84 (0.82-0.85). Predictive variables including: lowest oxygen saturation, temperature; or history of hypertension,: diabetes, hyperlipidemia, or obesity, were common to all ML models. DISCUSSION/SIGNIFICANCE: A predictive model identifying adult ED patients with COVID-19 at risk for return hospital admission within 30 days is feasible. Ensemble/boot-strapped classification methods outperform the single tree CART method. Future efforts may focus on the application of ML models in the hospital setting to optimize allocation of follow up resources.

OBJECTIVES/GOALS: A collaboration among Indiana CTSI community health partnerships (CHeP), bioethics, and regulatory programs identified and reviewed human research protection training programs targeting community engaged research, and pilot tested CIRTification with community partners working across a range of contexts. METHODS/STUDY POPULATION: We searched community human research protection training programs from across the county, identified three, examined each based upon criteria identified by community partners (time, relevance, online delivery) and our Human Research Protection Program (HRPP), and selected CIRTification (CIRT) to pilot. Ten community research partners volunteered to complete CIRT and a debriefing interview. Four completed CITI training previously. Participants included local and state-wide organizations, a resident, a state agency, and a hospital, and came from rural and urban communities. Interviews covered practical issues (ease of use, language, time), relevance, and comparison to CITI. Results were shared with HRPP for approval. RESULTS/ANTICIPATED RESULTS: Most felt CIRT was easy to navigate and engaging, and those who had done CITI felt CIRT was more relevant and engaging. The sections on historical background and recruitment were cited as most valuable. Suggestions were made to increase the diversity of examples beyond health care research. Community members mentioned several applications for CIRT including: (1) helping their own community work; (2) empowering them to be an advocate; (3) referring others to CIRT; (4) influencing approaches to recruitment and community engagement; and (5) applying ethics principles to their other community work. The Human Research Protection Program approved CIRT in place of CITI for community researchers. DISCUSSION/SIGNIFICANCE: Our process represents collaboration across the Indiana CTSI, HRPP and community partners, and use of best practices. Exemplifying “nothing about us without us”, actions were based on direct input from community partners, with the goal of decreasing barriers to engaging communities in research.

OBJECTIVES/GOALS: The Hispanic-In-Research Capability Endowment Phase (HiREC) Phase I Award supports research academic formation of researchers in Puerto Rico. Since 2011, HiREC provided critical infrastructure resources to develop the Clinical and Translational Research (CTR) workforce. We explored the awardees research career advancements and outcomes. METHODS/STUDY POPULATION: The target population of Phase I Award was young faculty and early-career investigators admitted to the Postdoctoral Master of Science in CTR Program. Eleven awardees were supported from 2011to 2020. A survey was administered via REDCap platform and all awardees were invited by email to participate. Data was collected from 03/15/21 to 05/15/21, including weekly follow-up by email and text messages to increase response rate and 100% responded. Descriptive analyses were performed in SPSS VS 27. The 63.6% was female and 54.6% MD. Most were Hispanic faculty and investigators (36.4%) or were at the clinical practice (36.4%). The 45.5% were affiliated to an academic institution or healthcare entrepreneur RESULTS/ANTICIPATED RESULTS: Awardees top career goals were: combine research & teaching-faculty (36.4%), clinical practice (36.4%) and Principal Investigator (PI) in a research institution (36.4%). The 81.8% of awardees achieved those goals and 18.2% are working-on it. A total of 57 grants were submitted (M=10, SD=10.9) and 42.1% funded. Most awardees submitted grants as PI (45.6%) or Co-I (42.1%). Additional outcomes were: 49 peer-reviewed publications, 67 posters and 21 oral presentations. Awardees expressed that this award: provided resources and necessary tools to support the research career pathway; served to develop essential research capabilities, knowledge and skills; and was a unique opportunity to protected-time for research. DISCUSSION/SIGNIFICANCE: HiREC provided resources, opportunities, and tools to remove barriers and facilitate career pathways of Hispanic investigators. Awardees achieved their career goals, their grant success rate was over 40%; received R-grants awards and published over 45 articles. This award model developed promising Hispanic researchers.

OBJECTIVES/GOALS: Researchers include community health workers and promotoras (CHW/Ps) on research teams to increase community engagement; however, no formal training on research best practices exists for this group. Study objectives were to examine perceived relevance of a new culturally and linguistically appropriate CHW/P training and optimal delivery modes. METHODS/STUDY POPULATION: We conducted six focus groups (FGs), three each in English and Spanish, at three study sites, University of Florida, University of Michigan, and University of California Davis from February to August 2021. The CHWs/Ps were purposively selected to include diverse age, race/ethnicity, educational level, and work experience. Separate FGs were conducted for CHWs/Ps in English and Spanish as appropriate. All FGs were audio recorded, translated to English from Spanish, transcribed and analyzed using RADaR (Rigorous and Accelerated Data Reduction) technique. RESULTS/ANTICIPATED RESULTS: Forty CHWs/Ps (95% women, mean age 45) participated, with the majority (58%) identifying as Hispanic/Latino. Of the sample, most identified as White (50%) or Black (25%). The proposed training was mentioned as relevant and would help them to be confident, comfortable, knowledgeable and effective in the community. Online training, though advantageous due to its flexibility also reportedly had barriers such as internet access, computer availability and technological know-how of CHWs/Ps. A hybrid training approach, online plus peer-led, was recommended due to the importance of personal guidance by an experienced CHW/P’ especially for a newly recruited CHW/P. DISCUSSION/SIGNIFICANCE: Findings indicated that a culturally and linguistically appropriate CHW/P training that is flexible and easily accessible in its mode of delivery is relevant and useful. In-person guidance to a new CHW/P was reported as an important training component. Poster will include the detailed quotes on relevance, usefulness, and mode of delivery of training.

OBJECTIVES/GOALS: Vaccination for COVID-19 is a primary public health strategy to control the pandemic. In this study, we examined how various sociodemographic variables influence rural residents intentions to receive the COVID-19 vaccine. We also examined the role of distrust in healthcare organizations in these intentions. METHODS/STUDY POPULATION: sing the electronic medical records of an academic healthcare institution in central Pennsylvania, we obtained names and addresses of patients who had been an inpatient or outpatient within the prior three years, were 18 years or older, and who resided in a community defined as rural by the Commonwealth of Pennsylvania. The survey included three statements about the intent to receive the COVID-19 vaccine, an open-ended question about concerns regarding the vaccine, and validated scales for general trust and for distrust in healthcare organizations. All study variables were summarized to determine their distributions, and then bivariate binomial logistic regression analyses were conducted. Responses to the open-ended question were coded and used as variables in the bivariate analysis. RESULTS/ANTICIPATED RESULTS: Respondents reporting conservative political views were more likely (compared to those liberal political views) to never want to be vaccinated for COVID-19. Those who expressed distrust in healthcare organizations were less likely to want to be vaccinated soon. Conversely those who were more trusting said they were more likely to want to be vaccinated soon. Respondents dominant concerns about the COVID-19 vaccine were that it was new and that the process for its development was rushed. Respondents who believed that COVID-19 was a hoax were unlikely to ever want to be vaccinated, while those who distrusted the process in some way (new vaccine or rushed vaccine) were more likely to want to wait to be vaccinated. DISCUSSION/SIGNIFICANCE: These findings confirm the impact of political orientation on COVID-19 vaccination intention and suggest that distrust in healthcare organizations may prevent people from being vaccinated. These data provide evidence that people delaying vaccination hold different beliefs than those who will never vaccinate.

OBJECTIVES/GOALS: The goal of this study was to examine the attitudes of central Pennsylvania rural residents toward data sharing in the setting of the COVID-19 pandemic. We determined their willingness to provide cell phone data and personal information to public health staff investigating COVID-19 cases, as well as their concerns about sharing this information. METHODS/STUDY POPULATION: We used the electronic medical records of an academic healthcare institution in central Pennsylvania to obtain names and addresses of patients who had visited an outpatient clinic or been an inpatient within the prior three years, were 18 years or older, and who resided in a community defined as rural by the Commonwealth of Pennsylvania. The survey included four statements about contact tracing, three statements about intent to receive the COVID-19 vaccine, and validated scales for general trust and for distrust in healthcare organizations. All study variables were summarized to determine their distributions, and bivariate binomial logistic regression was conducted. A multivariable model including all of the independent variables was then fit for each outcome variable. RESULTS/ANTICIPATED RESULTS: The response rate was 19.5%. 95 % of respondents were white, 56% were female, and nearly two-thirds were older than 60 years. Binomial logistic regression showed that both distrust in healthcare organizations and political values influenced respondents willingness to share information with contact tracers as well as their concerns about sharing. In multivariate analysis, political values were a consistent predicator of willingness to share and concerns about sharing. Respondents who indicated that they wanted to get vaccinated as soon as possible were significantly more likely than those who did not want to be vaccinated to be willing to share their cell phone location data and personal data. Conversely, they were less likely to be concerned with these data being shared without their permission. DISCUSSION/SIGNIFICANCE: Understanding rural residents concerns about sharing personal information is critical if we are to develop successful strategies for lessening the impact of COVID-19 and managing future pandemics. This study is a first step in eliciting such concerns in the context of COVID-19and has implications for directing a successful pandemic response.

OBJECTIVES/GOALS: The objective of this research is to begin documenting barriers to regenerative care to proactively address issues of accessibility and determine and implement interventions in anticipation of equitable care. We will explore the accessibility of Platelet Rich Plasma (PRP) for the treatment of knee osteoarthritis (Knee OA) METHODS/STUDY POPULATION: This research has two components. First, retrospective chart analysis using electronic databases to gather factors such as sex, race, ethnicity, disease severity, price, insurance, and treatments. Second. Prospective survey to gather the information (income, employment, education level) that are not found in the chart. Patients with knee OA conditions who received standard care will be compared to knee OA patients who received the novel PRP treatment. Statistical prediction modeling will be employed to determine the probability of receiving novel regenerative PRP treatment based on gathered explanatory variables. Our sample size is about 1000 patients per group (PRP group vs standard care group). Patients are from the three Mayo sites (Rochester, Arizona, Florida) as well as Detroit Medical Center. RESULTS/ANTICIPATED RESULTS: Our preliminary analysis shows that only a homogenous of patients (white) are receiving the novel PRP regenerative care to treat knee OA even though African Americans suffer from knee OA at a much greater rate. However, we still don’t know what is the main driver of this homogeneity. We anticipate that insurance coverage and out-of-pocket cost of care for PRP to be a huge barrier. Also, we are anticipating the lack of knowledge about PRP and its level 1 meta-analysis efficacy, as well as physician bias for not recommending PRP to certain underrepresented populations could play a role as well. We plan to order the level of influence of each barrier for each sex, race, and ethnicity, so intervention can be personalized and targeted for each population of interest. DISCUSSION/SIGNIFICANCE: Almost half of Americans live with at least one chronic medical condition and regenerative medicine holds tremendous promise to address many disease categories. To design any intervention to increase access requires knowledge about barriers in regenerative care, which is why this research is very critical now before the wide implementation of care.

OBJECTIVES/GOALS: Disparities in pediatric kidney transplantation (KT) result in reduced access and worse outcomes for minority children. We aimed to assess the impact of recent systemic changes on these disparities. METHODS/STUDY POPULATION: Retrospective cohort study of pediatric patients utilizing data from the United States Renal Data System (USRDS) and Scientific Registry of Transplant Recipients (SRTR). We compared access to transplantation, time to deceased donor kidney transplant (DDKT), and allograft failure (ACGF) using Cox proportional hazards in the 4 years preceding KAS to the 4 years post-KAS implementation. RESULTS/ANTICIPATED RESULTS: Compared to the pre-KAS era, patients post-KAS were more likely to be pre-emptively listed (26.8% vs 38.1%, p<0.001) and pre-emptively transplanted (23.8% vs 28.0%, p<0.001), however these benefits were not uniform across racial groups. Only 12.7% and 15.7% of Black and Hispanic children received a pre-emptive transplant compared to 29.6%, 49.8% and 54.4% of White, Asian and Other race children respectively. Compared to White children, Black and Hispanic children had a lower likelihood of transplant listing within 2 years of first dialysis service aHR 0.67 (0.59-0.76) and 0.82 (0.73-0.92), in the post-KAS era. Time to DDKT after listing was comparable across all racial groups in both eras. Black children have disproportionally worse 5-yr ACGF, aHR 1.50 (1.08-2.09), p=0.02. DISCUSSION/SIGNIFICANCE: After KAS implementation there remains equity in time to DDKT, however disparities persist in transplant listing and ACGF among Black children. Further studies are needed to identify granular SES factors impacting delayed referral and systemic barriers to transplant, as well as risk factors for poor allograft outcomes among minority children.

OBJECTIVES/GOALS: Patients with nsCL/P are prone to infections due to their open like wound cleft and immune system susceptibility. COVID-19 affected nsCL/P patients access to care and treatment delays. This study will determine COVID-19 infection risk between children with nsCL/P compared to those unaffected. METHODS/STUDY POPULATION: Retrospective cohort of children 5 years old and under with nsCL/P (exposed group) and children without nsCL/P (unaffected group); matched by age and gender. Participants will be selected from ongoing case-control study (n=500), School of Dental Medicine, and Pediatric University Hospital. Power analysis will calculate minimum sample size (power=0.80 alpha=0.05). Exclusion criteria: syndromic clefts, patients without diagnosis information and with history of co-morbidity. Other bacterial and viral infections present at the time of COVID-19 diagnosis, sex, age, geographic location, COVID-19 vaccination status and others will be considered as possible cofounders. Descriptive statistics, Chi-square, Odds Ratios at 95% confidence intervals and multiple logistic regression will be estimated. RESULTS/ANTICIPATED RESULTS: We hypothesize that we will identify an increased risk of COVID-19 infection in children with nsCL/P than in those unaffected or children without nsCL/P. Children with nsCL/P will also have an increased risk of symptoms and complications of COVID-19 infection than those unaffected. DISCUSSION/SIGNIFICANCE: Knowing the increased risk of COVID-19 infection in children with nsCL/P will aid to prioritize treatment. If a higher risk of COVID-19 infection is found, it will generate a need to modify elective surgery status to semi-elective; minimizing delayed treatments, unnecessary hospitalizations, complications and increased cost of treatment.
