Abstract Many patients in the emergency department present with signs and symptoms that arouse concern for sepsis; however, other explanations are also possible. There are currently no rapid tests used in clinical practice that reliably distinguish the presence of a bacterial or viral infection vs. a non-infectious etiology and can predict a patient’s likelihood to decompensate. The diagnostic and prognostic uncertainty in “gray zone” patients complicates the decision to begin therapy as clinicians need to balance the risk of withholding therapy vs. the risk of the therapy itself (e.g., overtreatment with antibiotics and hospitalization, which is costly, potentially harmful, and contributes to antibiotic resistance). The TriVerity™ Test uses isothermal amplification and machine-learning algorithms to quantify and interpret mRNA expression levels to determine both likelihood of bacterial infection, viral infection, or no infection, and whether the patient will likely require one or more critical interventions within 7 days. The three scores each fall into one of five interpretation bands ranging from Very high to Very low. Testing takes approximately 30 minutes using the proprietary Myrna™ Instrument with an operator hands-on-time of under one minute. We enrolled 1,222 patients from 22 emergency departments (ED) to validate the performance of the TriVerity Test. Patients were treated as per local standard of care and were followed for 28 days. Bacterial and viral TriVerity results were validated against clinically adjudicated infection status; the illness severity TriVerity result was validated against the need for at least one critical interventions within 7 days. The bacterial TriVerity result had high AUROC for the diagnosis of bacterial infection (0.83; 80% CI 0.81–0.85) and divided bacterial infection likelihood scores into five interpretation bands with increasing likelihood ratios of infection ranging from Very low (LR- 0.08, 80% CI 0.06–0.11) to Very high (LR + 8.04, 80% CI 5.72–11.78). The AUROC for the bacterial TriVerity result was significantly higher compared to AUROCs for C-reactive protein, procalcitonin or white blood cell count. Similarly, the viral TriVerity score showed high AUROC for the diagnosis of viral infection (0.91; 80% CI 0.90–0.93) and likelihood ratios from Very low (LR- 0.09, 80% CI 0.05–0.14) to Very high (LR + 40.93; 80% CI 29.11–79.23). The TriVerity Illness Severity score showed a high AUROC for the prediction of illness severity (0.77; 80% CI 0.77–0.81) with scores divided into five interpretation bands with increasing likelihood ratios ranging from Very low (LR- 0.22; 80% CI 0.14–0.33) to Very high (LR + 11.33; 80% CI 7.31–17.00). TriVerity illness severity results allowed marked re-classification of the risk for “ICU-level care” as compared to clinical assessment (qSOFA scores) alone. In conclusion, TriVerity provides rapid, highly accurate and actionable results for the diagnosis and prognosis of patients with suspected acute infection and/or sepsis, supporting a major unmet medical need. TriVerity may improve personalized management of patients with suspected acute infections and suspected sepsis for improved overall healthcare outcomes.

Importance In 2022, the US House of Representatives passed a bipartisan resolution (House of Representatives Resolution 1118 at the 117th Congress [2021-2022]) calling for meaningful nutrition education for medical trainees. This was prompted by increasing health care spending attributed to the growing prevalence of nutrition-related diseases and the substantial federal funding via Medicare that supports graduate medical education. In March 2023, medical education professional organizations agreed to identify nutrition competencies for medical education. Objective To recommend nutrition competencies for inclusion in medical education to improve patient and population health. Evidence Review The research team conducted a rapid literature review to identify existing nutrition-related competencies published between July 2013 and July 2023. Additional competencies were identified from learning objectives in selected nutrition, culinary medicine, and teaching kitchen curricula; dietetic core competencies; and research team–generated de novo competencies. An expert panel of 22 nutrition subject matter experts and 15 residency program directors participated in a modified Delphi process and completed 4 rounds of voting to reach consensus on recommended nutrition competencies, the level of medical education at which they should be included, and recommendations for monitoring implementation and evaluation of these competencies. Findings A total of 15 articles met inclusion criteria for competency extraction and yielded 187 competencies. Through review of gray literature and other sources, researchers identified 167 additional competencies for a total of 354 competencies. These competencies were compiled and refined prior to voting. After 4 rounds of voting, 36 competencies were identified for recommendation: 30 at both undergraduate and graduate levels, 2 at the undergraduate level only, and 4 at the graduate level only. Competencies fell into the following nutrition-related themes: foundational nutrition knowledge, assessment and diagnosis, communication skills, public health, collaborative support and treatment for specific conditions, and indications for referral. A total of 36 panelists (97%) recommended nutrition competencies be assessed as part of licensing and board certification examinations. Conclusions and Relevance These competencies represent a US-based effort to use a modified Delphi process to establish consensus on nutrition competencies for medical students and physician trainees. These competencies will require an iterative process of institutional prioritization, refinement, and inclusion in current and future educational curricula as well as licensure and certification examinations.

Abstract Introduction: Current guidelines state the effectiveness of desmopressin to reduce hematoma expansion in antiplatelet-related intracerebral hemorrhage (ICH) is uncertain. This study sought to determine if desmopressin decreased hematoma expansion in ICH patients on antiplatelet agents. Methods: We conducted a multi-center, retrospective propensity-matched cohort study at 11 US emergency departments (ED) that participate in EMPHARM-NET. Adult patients ≥18 years with a primary diagnosis of spontaneous ICH on antiplatelets prior to admission from January 1, 2017 through May 1, 2021 were included. The primary endpoint was good or excellent hemostatic efficacy within the first 24 hours following ICH between patients that did and did not receive desmopressin. Brain imaging was reviewed using 3D-Slicer by blinded expert physicians. Results: Overall, 1408 patients were evaluated for inclusion. A total of 324 patients were included, of which 13.8% (n=45) received desmopressin and 86.1% (n=279) did not. After propensity matching, 35 patients receive desmopressin compared to 140 controls. Baseline hematoma volume (27.6 mL vs. 2.1 mL) and was significantly higher in the desmopressin group. The primary endpoint of good or excellent hemostatic efficacy was similar between groups (74.3% desmopressin group vs. 85% control group, -10.7% [-28.1% to 6.7%]). There was no difference in secondary outcomes. Conclusion: In this multicenter cohort, patients receiving desmopressin had higher baseline intraparenchymal hematoma volume, and did not appear to result in improved hemostatic efficacy relative to the control group. These results suggest against routine administration of desmopressin for antiplatelet-related ICH, though future study in a randomized trial design is necessary.

Background: Mohs micrographic surgery (MMS) is a promising treatment modality for melanoma in situ (MIS). However, variations in surgical technique limit the generalizability of existing data and may impede future study of MMS in clinical trials. Methods: A modified Delphi method was selected to establish consensus on optimal MMS techniques for treating MIS in future clinical trials. The Delphi method was selected due to the limited current data, the wide range of techniques used in the field, and the intention to establish a standardized technique for future clinical trials. A literature review and interviews with experienced MMS surgeons were performed to identify dimensions of the MMS technique for MIS that (1) likely impacted costs or outcomes of the procedure, and (2) showed significant variability between surgeons. A total of 8 dimensions of technical variation were selected. The Delphi process consisted of 2 rounds of voting and commentary, during which 44 expert Mohs surgeons across the United States rated their agreement with specific recommendations using a Likert scale. Results: Five of eight recommendations achieved consensus in Round 1. All 3 of the remaining recommendations achieved consensus in Round 2. Techniques achieving consensus in Round 1 included the use of a starting peripheral margin of ≤5 mm, application of immunohistochemistry, frozen tissue processing, and resecting to the depth of subcutaneous fat. Consensus on the use of Wood’s lamp, dermatoscope, and negative tissue controls was established in Round 2. Conclusions: This study generated 8 consensus recommendations intended to offer guidance for Mohs surgeons treating MIS. The adoption of these recommendations will promote standardization to facilitate comparisons of aggregate data in multicenter clinical trials.

ABSTRACT Introduction The Special Warfare Training Wing and Special Warfare Human Performance Support Group (HPSG; all-co-authors) were established in fiscal year (FY) 2019 to consolidate and oversee all Air Force Special Warfare (AFSPECWAR) training and provide embedded medical and human performance support to candidates with the goal of improving graduation rates and the longevity of the AFSPECWAR operator. The purpose of this manuscript is to assess the impact of the HPSG on AFSPECWAR graduation rates, musculoskeletal injury (MSKI) incidence, and cost. Materials and Methods Graduation rates, MSKI incidence (including incidence density and cumulative incidence probability), and MSKI-related health care costs were assessed across all AFSPECWAR training pipelines spanning 8 FYs 2015–22, including Indoctrination, Assessment, and Selection Courses (Selection); Tactical Air Control Party (TACP); Special Tactics (ST), and Guardian Angel (GA). Results A total of 5,728 distinct candidates were assessed over the time frame. There were significant decreases in attrition when comparing the HPSG era (FY 19–22) with the prior 4-year period for the ST (47% vs. 82% graduates) and TACP (34% vs. 41% graduates) training pipelines. The corresponding Selection (36% graduates) and GA (80% graduates) pipeline attrition rates remained stable. MSKI incidence rates (both incidence density and cumulative incidence probability) overall were not significantly different when comparing the pre-HPSG and HPSG time frames; however, they varied between the two time frames by course. GA candidates had a decrease in MSKI during the apprentice course in the HPSG era compared with the pre-HPSG era (2.4–1.0 cases per 100 trainee weeks; P < .001), which corresponds to a nearly 20% reduction in the cumulative incidence probability (i.e., proportion of trainees injured) after 10 weeks of course. For ST and TACP courses, however, significantly increased incidence of MSKI was observed when comparing the two time frames (P < .001), while for Selection courses, the rates remained stable. A significant reduction in the cost of MSKI-related management (62% total relative value units, 83% total costs) was observed. Conclusion The impact of the HPSG on attrition, MSKI incidence, and cost-of-care was not consistent across all training pipelines; however, taken together, there were no increases in attrition, and the cost of MSKI management was significantly lower.

7072 Background: LG-NHL is mostly incurable, imposing a prolong impact of cancer care burden for pts. This study aimed to quantify the burden of MH conditions in pts with newly diagnosed chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), follicular lymphoma (FL), mantle cell lymphoma (MCL), Waldenström macroglobulinemia (WM), or marginal cell lymphoma (MZL). Methods: A retrospective study was conducted using Optum Clinformatics Data Mart to identify pts ≥18 years with ≥1 new diagnosis for CLL, FL, MCL, WM, or MZL from 6/2016-6/2022 (index period). Pts were required to be continuously enrolled for 60 days pre- and 365 days post-index date, defined as the date of first cancer diagnosis. Incidence and prevalence of MH conditions of interest (anxiety, depression, stress reaction/adjustment disorder, insomnia, post-traumatic stress disorder [PTSD]) were categorized based on if diagnoses were post- or pre-index date. All-cause healthcare resource utilization (HCRU) and costs were measured during the 1-yr follow-up period. Results: Approximately half of newly diagnosed 36,054 LG-NHL pts (CLL/SLL=48.0%; FL=52.7%; MCL=57.2%; WM=50.5%; MZL=52.5%) had either an incident (19.4-25.7%) or prevalent (28.6-32.1%) MH condition diagnosis following their cancer diagnosis (Table). There were no significant demographic differences in pts with and without MH conditions. LG-NHL pts suffered most from anxiety (30.9-38.2%) and depression (27.5-31.9%), followed by insomnia (16-23.1%), stress (10.3-13.5%), and PTSD (1.4-1.9%). Median time from cancer diagnosis to onset of a MH condition was 334 days for CLL/SLL, 301 for FL, 248 for MCL, 351 for WM, and 328 for MZL. LG-NHL pts with an identifiable MH diagnosis had significantly higher costs and HCRU compared to those without; for example, in CLL/SLL pts with MH diagnosis, outpatient visits were 1.4 times higher, inpatient admissions 3.0 times higher, and costs 2.1 times higher than those without (all P=0.0001). HCRU and cost increases were also observed in MCL, FL, WM, and MZL pts with MH diagnosis. Conclusions: This real-world study uncovered a high proportion of LG-NHL patients suffer from MH conditions, incurring higher financial burden than those without. With advancements in new treatments, there remains unmet need of MH burden in these pts. [Table: see text]
