The Influence Of Older Age On Rbc Transfusion Decisions In Icu Patients, Caroline Schaap, Jorinde Raasveld, Florian Reizine, Boillot Corentin, Jimmy Schenk, Sanne De Bruin, Merijn Reuland, Claudia Van Den Oord,, Andrew Flint, Marcus Lance

Anaesthesiology, East Africa

Objectives: RBC transfusions are common in the ICU. Recent studies suggest that a restrictive transfusion policy is noninferior or superior to a liberal policy. However, few studies focus on the influence of age in transfusion. In elderly ICU patients, reduced physiologic reserves may shift the perceived risk-benefit balance of transfusion, potentially leading to different transfusion practices. This study examines whether transfusion practices in ICU patients differ across patient age.

Design: This is a substudy of the International Point Prevalence Study of ICU Transfusion Practices (InPUT), a global, multicenter, prospective observational cohort study.

Setting: ICUs from 233 centers …

Clinical And Non-Clinical Factors Associated With Early Discharge In Pediatric Non-Trauma Patients Transported By Rotor Wing, Jordon Mitzelfelt, Lisa Pruitt, Amy Papa, Ashley K. Sherman, David Juang, Sarah Brunner, Asdis Finnsdottir Wagner, Jennifer Flint

Posters

Objective: Helicopter emergency medical services (HEMS) are crucial for transporting critically ill children to definitive care, however, rising costs and relative risks of this type of transportation necessitate careful evaluation of potential over-utilization. Current literature primarily focuses on pediatric trauma patients, leaving a significant gap in data regarding non-trauma pediatric HEMS transports and the influence of non-clinical factors such as referral hospital distance, resources, and capabilities on transport decisions. This study aims to address these gaps by examining non-trauma pediatric HEMS patients and identifying associated clinical and non-clinical factors related to early hospital discharge (< 24 hours). Methods: This retrospective, single-center study includes pediatric patients with medical and non-trauma surgical diagnoses transported by HEMS between April 1, 2021 and March 31, 2024. Clinical data were extracted from transport team records and the hospital’s electronic health records. Analyses were performed to identify factors associated with discharge within 24 hours of admission. To identify predictors of early discharge, we analyzed clinical factors including chief complaint, pre-transport vascular access, transport crew interventions (medication administration and procedures), respiratory assistance, and Pediatric Age-Adjusted Shock Index (SIPA) scores. Additionally, we examined the impact of the initial admit unit, and medical support required within the first 24 hours of hospitalization. Non-clinical predictors included the referring hospital’s status (critical access and/or rural designation) and the time of transport. Results: A total of 568 patients were transported by HEMS, of whom 88 (15%) were discharged within 24 hours. Patients in the early discharge group were more likely to present with neurologic chief complaints (40%), whereas those remaining hospitalized beyond 24 hours more frequently presented with respiratory complaints (40%). Normal SIPA scores both prior to and at the conclusion of transport were significantly associated with early discharge (p=0.012 and p=0.011, respectively). Furthermore, patients requiring no medications or respiratory assistance during transport, or no respiratory support within the first 24 hours of admission, were significantly more likely to be discharged early (p< 0.001). Notably, all patients with central access prior to transport remained admitted for more than 24 hours (p=0.004). Regarding non-clinical factors, patients transported from designated rural hospitals were more likely to experience early discharge (p< 0.001). Conclusion: These results characterize the pediatric non-trauma HEMS population and identify key predictors of early hospital discharge. This data is essential for developing standardized dispatch criteria to mitigate over-utilization and ensure high-acuity transport is reserved for the most appropriate patients.

Deep Learning Based Approaches For Low Cost Defense Detection, Adele J. Noel-Rickert

All NMU Master's Theses

Pulmonary fibrosis is a progressive interstitial lung disease characterized by the accumulation of fibrotic tissue within the lungs, leading to impaired respiratory function and reduced quality of life. Early detection is important for disease management; however, accurate diagnosis often relies on high-resolution computed tomography (CT), which may not be accessible in all clinical settings. Chest radiography provides a lower-cost and widely available imaging modality, but interpretation of chest X-rays for fibrotic disease can be challenging due to subtle radiographic patterns and overlapping anatomical structures. This thesis investigates the use of multimodal deep learning techniques to assist in pul- monary fibrosis …

Exploring How Parental Involvement Impacts Police Encounters And Delinquent Behaviors Among Black Adolescent Girls, Danielle Porter, Elizabeth A. Otto, Dyamon Brown, Jasmine Alli, Robyn Douglas, Noni Gaylord-Harden

Presentations

Adolescents’ contact with police is a complex outcome that is influenced by both individual behavior and the broader social context. Specifically, while delinquent behavior can lead to more police contact (Crutchfield et al., 2012), hyper-surveillance often occurs in marginalized communities, increasing unjustified police contact for youth of color (Campos-Manzo et al., 2020; Geller, 2021). Indeed, racial disparities in police contact during adolescence persist even after accounting for delinquent behavior (Campos-Manzo et al., 2020; Crutchfield et al., 2012). Thus, it is important to identify factors that may protect Black youth from contact with police. Parental involvement refers to parents’ active and …

Antibiotic-Pathogen Concordance In Pediatric Complicated Community-Acquired Pneumonia, Makenna Steger Md, Marina Dantas Md, Mscr, Berina Karisik Do, Smit Shah, Alaina Burns Pharmd, Jessica Markham

Presentations

Background Complicated community-acquired pneumonia (cCAP)—defined by effusion, empyema, abscess, cavitation, or necrosis—is associated with worse outcomes than uncomplicated pneumonia. Methicillin resistant Staphylococcus aureus (MRSA) data in cCAP are limited and often merged with uncomplicated cases. Although guidelines recommend MRSA coverage only in select cases, it is empirically used in >70% of encounters. Lack of pathogen identification likely drives overuse due to diagnostic uncertainty.

Occupational Epidemiology Of Acral Lentiginous Melanoma, Lily Guo, Robin Kikuchi, April W. Armstrong, Suephy C. Chen

Department of Dermatology and Cutaneous Biology Faculty Papers

Acral lentiginous melanoma (ALM) classically presents in glabrous skin. Some studies suggest an association between mechanical stress and ALM development. People working jobs with long periods of standing/walking may be exposed to near-daily mechanical stress. To investigate the relationship between occupation type and ALM development, we performed a retrospective cohort study using Optum’s Clinformatics Database (2007—2023). We compared the risk of ALM in adults with occupational data (n = 9,270,935). Retired patients had the highest prevalence (0.081) and incidence per 1,000,000 person-years (0.514, 95% confidence interval = 0.487—0.542) of ALM. We performed multivariate logistic regression, adjusted for demographics and insurance, …
