Coastal wetlands are hotspots of carbon sequestration, and their conservation and restoration can help to mitigate climate change. However, there remains uncertainty on when and where coastal wetland restoration can most effectively act as natural climate solutions (NCS). Here, we synthesize current understanding to illustrate the requirements for coastal wetland restoration to benefit climate, and discuss potential paths forward that address key uncertainties impeding implementation. To be effective as NCS, coastal wetland restoration projects will accrue climate cooling benefits that would not occur without management action (additionality), will be implementable (feasibility) and will persist over management-relevant timeframes (permanence). Several issues add uncertainty to understanding if these minimum requirements are met. First, coastal wetlands serve as both a landscape source and sink of carbon for other habitats, increasing uncertainty in additionality. Second, coastal wetlands can potentially migrate outside of project footprints as they respond to sea-level rise, increasing uncertainty in permanence. To address these first two issues, a system-wide approach may be necessary, rather than basing cooling benefits only on changes that occur within project boundaries. Third, the need for NCS to function over management-relevant decadal timescales means methane responses may be necessary to include in coastal wetland restoration planning and monitoring. Finally, there is uncertainty on how much data are required to justify restoration action. We summarize the minimum data required to make a binary decision on whether there is a net cooling benefit from a management action, noting that these data are more readily available than the data required to quantify the magnitude of cooling benefits for carbon crediting purposes. By reducing uncertainty, coastal wetland restoration can be implemented at the scale required to significantly contribute to addressing the current climate crisis.

COVID-19 vaccine uptake in healthcare personnel (HCP) is poor. A cross-sectional survey study of behavioral health HCP was performed. Commonly identified reasons for vaccination were protecting others and oneself. Reasons against were a lack of perceived protection, dosing intervals, and side effects. Assessing vaccination attitudes can assist in uptake strategy.

Background: Recent evidence has shown that the updated COVID-19 bivalent booster is effective in preventing COVID-19 compared with no previous vaccination and prior monovalent vaccination. Despite its effectiveness, uptake has been poor, and a minority of eligible recipients have received the booster. Understanding healthcare worker (HCW) attitudes for and against voluntary uptake of the bivalent booster dose against COVID-19 can help guide communication strategy to maximize uptake. In this survey study, we investigated attitudes toward updated and/or bivalent booster uptake in a behavioral health hospital shortly after a COVID-19 outbreak. Methods: A survey tool was developed and sent to all HCWs at the Yale New Haven Psychiatric Hospital in December 2022. The survey queried demographic data, job category, history of COVID-19, prior COVID-19 vaccinations, perception of COVID-19 exposure, and updated and/or bivalent booster doses. The survey was administered several weeks after a COVID-19 outbreak on multiple inpatient behavioral health units. Receipt of the COVID-19 primary vaccination series and the first booster dose were mandated for HCWs; however, receipt of the bivalent booster was voluntary. Results: The survey was sent to 664 HCWs with primary assignments in behavioral health settings. In total, 182 (27.4%) provided complete responses to the survey and are included in these data. Moreover, 91 HCWs (50.0%) reported previously having COVID-19 at least once. Overall, 100 HCWs (55.0%) received the bivalent booster. The most identified reasons for receiving the bivalent booster were wanting to protect family and friends (n = 113), importance of staying healthy (n = 112), and protecting colleagues and patients (n = 103). The most identified reasons for not wanting to receive the bivalent booster dose were not thinking it provides additional protection (n = 33), “too many” shots already received (n = 31), and concern about side effects (n = 30). Discussion: Bivalent booster dose uptake in HCWs on behavioral health units shortly after a COVID-19 outbreak was greater than the general population. HCWs reported varying reasons for and against receipt of the bivalent booster dose, with the most common being protection of family and friends and perceptions of no additional protection, respectively. A limitation of this study was voluntary response bias, in which results are biased toward individuals more likely to receive a bivalent booster vaccine. It is unclear whether reasons for declining the vaccine are representative of HCWs who did not complete the survey. Assessing attitudes for the bivalent booster dose can assist in guiding communication and outreach strategies to increase vaccine uptake by HCWs.

Team participation in whole-school action research can assist the educational reform required for autistic students. Little is known about the experience of school community stakeholders engaged in the first stage of an implementation science process: evaluation of current practice. This study was designed to explore stakeholder experience and knowledge gained following a process of evaluation of whole-school practice related to the education of autistic students. A collective case study was employed across two Australian secondary schools, with team meetings designed to provide an opportunity for the self-evaluation process to take place and the data for the study to be generated. Thematic analysis was used to analyse the dialogue between participants during focus group discussions with each team. Findings are represented through six themes that provide insight for future practice. Both stakeholder teams reported that the evaluation process was a positive experience to engage in and resulted in a strengthening of knowledge about good practice for autistic students. Findings provide encouragement to other school teams engaging in a similar process; however, future teams may need to feel ready for this work and might benefit from the structure of a wider action-research cycle aligned to implementation science processes.

OBJECTIVES/GOALS: To increase the diversity of the health sciences research workforce, students from a variety of backgrounds must have the opportunity to participate in hands-on research experiences that highlight translating science to treating human disease. We developed a mentored translational research program for students from VCU and central Virginia HBCUs. METHODS/STUDY POPULATION: The Wright Regional Center for Clinical and Translational Science collaborated with the existing VCU Honors’ Summer Undergraduate Research Program (HSURP) to expand their summer research experience to URM students from our partner HBCUs. For 10 weeks, students worked with faculty mentors to learn research techniques and engage in research projects. Students also participated in career development sessions like developing a CV and choosing graduate programs, and at the end of HSURP, they shared formal presentations of their research with peers and mentors. HSURP students were provided housing and a stipend, and mentors were provided a stipend. A post-program assessment gathered feedback on research and personal skills gained, the program’s influence on their career goals, and overall experiences with HSURP. RESULTS/ANTICIPATED RESULTS: Nine students, 7 from VCU and 2 from Virginia State University participated in HSURP. Students were rising sophomores, juniors, and seniors, and 5 had previous research experience. Students worked on projects ranging from basic to social behavioral, community-placed research. All students rated the program as good or excellent. Post-program assessments showed all students believed they had a better understanding of ethical responsibilities of researchers, relevance of community-engaged and clinical/translational research, and interpreting journal articles after participating in the program. Four students reported they plan to continue working on their research projects during the academic year, and all students strongly agreed or agreed that HSURP prepared them for graduate or professional schools. DISCUSSION/SIGNIFICANCE: A program that combines hands-on research training and career development opportunities provides a robust research foundation for URM students, which can increase their participation in the translational science workforce. Future program development will include preprogram training modules to better prepare students for research experiences.

OBJECTIVES/GOALS: a) Explore topics related to AMC CRP job titles, descriptions, and pre-requisites for hire b) Describe impact of COVID-19 on the AMC CRP workforce c) Discuss opportunities for improving diversity in the CRP workforce d) Discuss opportunities to enhance institutional staffing culture to retain CRP workforce METHODS/STUDY POPULATION: Qualitative data from a series of workshop breakout sessions and open-text survey materials focusing on AMC CRP recruitment, retention and diversity were analyzed to inform content and recommendations for clinical research job titles and descriptions, pre-requisites, diversity, and current needs. RESULTS/ANTICIPATED RESULTS: While certain institutions have established competency-based frameworks for job descriptions and career ladders, standardization remains generally lacking across CTSA hubs. Significant hiring needs have reached exponential proportions across hubs, unable to meet current and projected clinical research goals. Data confirmed an urgent need for closing gaps in clinical research workforce at AMCs, especially for improving diversity and equity of personnel. Improved collaboration with human resource departments, engagement with principal investigators, and overcoming both organizational and resource challenges were suggested strategies, as well as pipeline development via outreach to universities, community colleges, and high schools to raise awareness of the professional pathways for CRPs. DISCUSSION/SIGNIFICANCE: Based on input from 130 CRP leaders at 38 CTSA hubs and 4 IDeA sites evaluating data from 23 breakout transcripts and ~92 surveys from the Collaborative Conversations Unmeeting, new opportunities emerged during the analysis. The findings will be summarized in a 2022 Synergy manuscript including best practice benchmarking recommendations.

Background: Antibiotic overuse contributes to antibiotic resistance and unnecessary adverse drug effects. Antibiotic stewardship interventions have primarily focused on acute-care settings. Most antibiotic use, however, occurs in outpatients with acute respiratory tract infections such as pharyngitis. The electronic health record (EHR) might provide an effective and efficient tool for outpatient antibiotic stewardship. We aimed to develop and validate an electronic algorithm to identify inappropriate antibiotic use for pediatric outpatients with pharyngitis. Methods: This study was conducted within the Children’s Hospital of Philadelphia (CHOP) Care Network, including 31 pediatric primary care practices and 3 urgent care centers with a shared EHR serving >250,000 children. We used International Classification of Diseases, Tenth Revision (ICD-10) codes to identify encounters for pharyngitis at any CHOP practice from March 15, 2017, to March 14, 2018, excluding those with concurrent infections (eg, otitis media, sinusitis), immunocompromising conditions, or other comorbidities that might influence the need for antibiotics. We randomly selected 450 features for detailed chart abstraction assessing patient demographics as well as practice and prescriber characteristics. Appropriateness of antibiotic use based on chart review served as the gold standard for evaluating the electronic algorithm. Criteria for appropriate use included streptococcal testing, use of penicillin or amoxicillin (absent β-lactam allergy), and a 10-day duration of therapy. Results: In 450 patients, the median age was 8.4 years (IQR, 5.5–9.0) and 54% were women. On chart review, 149 patients (33%) received an antibiotic, of whom 126 had a positive rapid strep result. Thus, based on chart review, 23 subjects (5%) diagnosed with pharyngitis received antibiotics inappropriately. Amoxicillin or penicillin was prescribed for 100 of the 126 children (79%) with a positive rapid strep test. Of the 126 children with a positive test, 114 (90%) received the correct antibiotic: amoxicillin, penicillin, or an appropriate alternative antibiotic due to b-lactam allergy. Duration of treatment was correct for all 126 children. Using the electronic algorithm, the proportion of inappropriate prescribing was 28 of 450 (6%). The test characteristics of the electronic algorithm (compared to gold standard chart review) for identification of inappropriate antibiotic prescribing were sensitivity (99%, 422 of 427); specificity (100%, 23 of 23); positive predictive value (82%, 23 of 28); and negative predictive value (100%, 422 of 422). Conclusions: For children with pharyngitis, an electronic algorithm for identification of inappropriate antibiotic prescribing is highly accurate. Future work should validate this approach in other settings and develop and evaluate the impact of an audit and feedback intervention based on this tool.

Background: Antibiotic resistance has increased at alarming rates, driven predominantly by antibiotic overuse. Although most antibiotic use occurs in outpatients, antimicrobial stewardship programs have primarily focused on inpatient settings. A major challenge for outpatient stewardship is the lack of accurate and accessible electronic data to target interventions. We sought to develop and validate an electronic algorithm to identify inappropriate antibiotic use for outpatients with acute bronchitis. Methods: This study was conducted within the University of Pennsylvania Health System (UPHS). We used ICD-10 diagnostic codes to identify encounters for acute bronchitis at any outpatient UPHS practice between March 15, 2017, and March 14, 2018. Exclusion criteria included underlying immunocompromising condition, other comorbidity influencing the need for antibiotics (eg, emphysema), or ICD-10 code at the same visit for a concurrent infection (eg, sinusitis). We randomly selected 300 (150 from academic practices and 150 from nonacademic practices) eligible subjects for detailed chart abstraction that assessed patient demographics and practice and prescriber characteristics. Appropriateness of antibiotic use based on chart review served as the gold standard for assessment of the electronic algorithm. Because antibiotic use is not indicated for this study population, appropriateness was assessed based upon whether an antibiotic was prescribed or not. Results: Of 300 subjects, median age was 61 years (interquartile range, 50–68), 62% were women, 74% were seen in internal medicine (vs family medicine) practices, and 75% were seen by a physician (vs an advanced practice provider). On chart review, 167 (56%) subjects received an antibiotic. Of these subjects, 1 had documented concern for pertussis and 4 had excluding conditions for which there were no ICD-10 codes. One received an antibiotic prescription for a planned dental procedure. Thus, based on chart review, 161 (54%) subjects received antibiotics inappropriately. Using the electronic algorithm based on diagnostic codes, underlying and concurrent conditions, and prescribing data, the number of subjects with inappropriate prescribing was 170 (56%) because 3 subjects had antibiotic prescribing not noted based on chart review. The test characteristics of the electronic algorithm (compared to gold standard chart review) for identification of inappropriate antibiotic prescribing were the following: sensitivity, 100% (161 of 161); specificity, 94% (130 of 139); positive predictive value, 95% (161 of 170); and negative predictive value, 100% (130 of 130). Conclusions: For outpatients with acute bronchitis, an electronic algorithm for identification of inappropriate antibiotic prescribing is highly accurate. This algorithm could be used to efficiently assess prescribing among practices and individual clinicians. The impact of interventions based on this algorithm should be tested in future studies.

Geothermal heat flux (GHF) is an important control on the dynamics of Antarctica's ice sheet because it controls basal melt and internal deformation. However, it is hard to estimate because of a lack of in-situ measurements. Estimating GHF from ice-borehole temperature profiles is possible by combining a heat-transfer equation and the physical properties of the ice sheet in a numerical model. In this study, we truncate ice-borehole temperature profiles to determine the minimum ratio of temperature profile depth to ice-sheet thickness required to produce acceptable GHF estimations. For Law Dome, a temperature profile that is within 60% of the local ice thickness is sufficient for an estimation that is within approximately one median absolute deviation of the whole-profile GHF estimation. This result is compared with the temperature profiles at Dome Fuji and the West Antarctic Ice Sheet divide which require a temperature profile that is 80% and more than 91% of the ice thickness, respectively, for comparable accuracy. In deriving GHF median estimations from truncated temperature profiles, it is possible to discriminate between available GHF models. This is valuable for assessing and constraining future GHF models.

Previous research in clinical, community, and school settings has demonstrated positive outcomes for the Secret Agent Society (SAS) social skills training program. This is designed to help children on the autism spectrum become more aware of emotions in themselves and others and to ‘problem-solve’ complex social scenarios. Parents play a key role in the implementation of the SAS program, attending information and support sessions with other parents and providing supervision, rewards, and feedback as their children complete weekly ‘home mission’ assignments. Drawing on data from a school-based evaluation of the SAS program, we examined whether parents’ engagement with these elements of the intervention was linked to the quality of their children’s participation and performance. Sixty-eight 8–14-year-olds (M age = 10.7) with a diagnosis of autism participated in the program. The findings indicated that ratings of parental engagement were positively correlated with children’s competence in completing home missions and with the quality of their contribution during group teaching sessions. However, there was a less consistent relationship between parental engagement and measures of children’s social and emotional skill gains over the course of the program.
