Association Of Higher Body Mass Index With Imaging Escalation And Operative Complexity In Pediatric Appendicitis, Ryan T. Davis, Sahithi Pemmasani, Margaret Menoch

Conference Presentation Abstracts

Background: Obesity may complicate clinical assessment and ultrasound (US) evaluation in children with appendicitis, potentially increasing reliance on computed tomography (CT). At the same time, national pediatric quality-improvement initiatives and ALARA-driven imaging pathways emphasize reducing CT use and promoting US-first approaches. Data examining how body mass index (BMI) influences diagnostic pathways within these modern low-radiation protocols are limited.

Objective: To determine whether higher BMI is associated with greater CT utilization, escalation from US to CT, nondiagnostic US examinations, emergency department (ED) length of stay (ED-LOS), and operative duration in children with appendicitis.

Design/Methods: This retrospective cohort study included patients < 18 years with surgically confirmed appendicitis presenting to a tertiary pediatric ED from January 1, 2010, to December 31, 2023. Consistent with prior dataset methodology, encounters were identified through structured EHR query using ICD-10 and CPT codes and restricted to unique first visits. A total of 2,275 children were included; BMI was available for 2,012 (88%). BMI was analyzed in quartiles. Imaging modality (US-only, CT-only, or CT after US) and operative duration (proxy for case complexity) were evaluated. χ² and Wilcoxon tests and odds ratios (OR) with 95% CI were used. IRB approval was obtained (Corewell Health IRB No. 2024-128).

Examining Health Disparities: An Observational Study On Peripheral Vascular Access Outcomes Among Hospitalized Patients, Charlotte O’Sullivan, Nicholas Mielke, Yuying Xing, Amit Bahl

Posters

Peripheral intravenous catheter (PIVC) placement is the most common invasive procedure performed in healthcare, with an estimated 90% of hospitalized patients requiring PIVC access during their stay. This equates to around two billion PIVCs used annually.1–3 Studies report 36% to 63% of catheters fail due to a variety of complications, including infiltration, occlusion, phlebitis, dislodgment, and infection. 2–6 These failures not only cause immediate patient discomfort and increased clinical workload but also have wider implications such as prolonged hospital stays and delays in critical treatments.2 The factors contributing to PIVC failure are multifaceted, involving clinical presentation, patient anatomy, provider skill …

Manual Versus Mechanical Cardiopulmonary Resuscitation Complications After Successful Resuscitation For Out-Of-Hospital Cardiac Arrest, Connie Chen, Jacob Keeley, Julian Sit, Robert Swor

Posters

Over 300,000 people in the United States annually suffer from an out of hospital cardiac arrest (OHCA); 90% of cases are fatal.1

EMS-treated OHCA approximately has a 30% rate of Return of Spontaneous Circulation (ROSC), but not all survive to hospital admission or discharge.2

Quality cardiopulmonary resuscitation (CPR) provides vital organ reperfusion until cardiac activity can be restored.

Mechanical CPR is increasingly being used for field OHCA care. It is most often performed by the Lund University Cardiopulmonary Assist System (LUCAS) device, a piston chest compressor which incorporates a mechanism for active chest recoil.

Benefits of mechanical CPR:

How Dry Is Too Dry? Dehydration Management Of Pediatric Patients In The Ed, Shruthi Rethi

Conference Presentation Abstracts

Background: Gastroenteritis and dehydration are some of the leading causes of morbidity within pediatric EDs in the US, with over 1.7 million visits and more than 70,000 hospitalizations. There are many different guidelines/standards on the definition of dehydration. Clinical exam guidance using dehydration scales have been explored (eyes, mucous membranes, and tears). However, use of them in practice is varied.
Electrolyte lab values have not been included in dehydration scales, as a cut off is difficult to determine to guide IV vs oral rehydration, or admission. There can be little overlap between clinical exam and laboratory results. Studies have shown …

Burning Questions: Ed Management Of Pediatric Burns At A Non-Burn Center, Aksay Vivek Nandavar

Conference Presentation Abstracts

Background: Burn Centers (BC) with higher burn admissions have lower burn-related mortality. Inaccurate diagnosis causes negative outcomes. Excess BC referral can overburden these centers. The American Burn Association (ABA) has standardized burn center referral criteria. Minimal data exists on its application for patients at non-burn centers (NBC). Pre-hospital management of pediatric burns is also not well-defined in literature. Evidence suggests that an accurate assessment of burn size and depth can be made with photography. But its use has not been studied in relation to ED care, only being used for child protective services (CPS) reports with burns.

Objective: Primary objective: …

Caterino, Subha V. Raman, Chadwick D. Miller

Conference Presentation Abstracts

Background and Objectives: Patients presenting to the Emergency Department (ED) with chest pain who have an indeterminate (detectable to mildly elevated) troponin are often further evaluated with tests that use ionizing radiation. We hypothesized that patients initially evaluated with stress cardiac magnetic resonance (CMR) imaging receive less ionizing radiation through 1-year of follow-up than those initially evaluated with invasive angiography. Methods: We conducted a secondary analysis of the CMR-IMPACT trial, which randomized adult patients at 4 U.S. sites (9/2013– 7/2018) with a contemporary troponin of 0.006–1.0 ng/mL to either CMR imaging or invasive angiography. Cumulative radiation exposure from coronary computed …

Conference Presentation Abstracts

Background and Objectives: Detection of ST-segment elevation myocardial infarctions (STEMI) are dependent on early acquisition of an ECG. American Heart Association guidelines require performing an ECG within 10 min for patients presenting with symptoms warranting STEMI screening. A delay in ECG acquisition causes delays in diagnosis and treatment, which is associated with worsened outcomes. However, previous work has shown there is limited success at achieving a door to ECG (D2E) time of Methods: This is a retrospective chart review study in which D2E time was measured for patients positive for STEMI ECG screening criteria in a large health system with …

Diuretic Dose Ratio Is Associated With Reduced Hospital Length Of Stay In Acute Heart Failure, Sarah Galla, Yuying Xing, Lihua Qu, David A. Berger

Conference Presentation Abstracts

Background and Objectives: Congestive heart failure (CHF) is anticipated to affect eight million Americans by 2030. Treatment for CHF exacerbation is centered around IV diuretics. There are no current studies indicating an optimal initial diuretic dose in the Emergency Department (ED), and our objective is to test our hypothesis that higher diuretic dose ratio may shorten hospital length of stay (LOS). Methods: We conducted a retrospective cohort study of a large health system from 2016 to 2022. We included patients admitted from the ED with a primary diagnosis of “CHF exacerbation” with a history of CHF and prescribed diuretics. Exclusions …

Lactate Expression, Mortality, And Length Of Stay In Emergency Department Patients With Sepsis And Intubation, Heaveen Ahdi, Nadine Talia, Ray Lee, Lili Zhao, Ronny Otero, David A. Berger

Conference Presentation Abstracts

Background and Objectives: Studies demonstrate that patients in septic shock with a lactate < 2 have a mortality between 20% to 46%. Our prior work reported that in emergency department (ED) patients with a second lactate ≥2 (lac), there is a two-fold increase in 30-day mortality when compared to patients with a second lactate < 2 (alac). On secondary analysis, we found that intubated patients with a second lactate ≤2 had a longer hospital length of stay (LOS). Our objective is to further scrutinize this 30-day mortality and LOS. Methods: This is a retrospective cohort study of an eight-hospital health system using data from the electronic medical record. Inclusion criteria consisted of patients ≥18 years of age who presented to the ED from 1/1/2017 to 11/30/2022 with ≥2 lactate levels measured in the ED, were diagnosed with sepsis, and admitted to the intensive care unit (ICU) within 24 h. We excluded lactate auto-expressors, pregnant patients, transfers, and those taken for a surgical procedure within 72 h of presentation. Patients were classified based on initial and second lactate as < 2 (alac) or ≥2 (lac). Multivariable regression analysis was performed for 30-day mortality and LOS, adjusting for vitals, BMI, DNR status, and intubation timing. Results: Of the 3100 patients who met inclusion criteria, 1285 patients were intubated and categorized based on their lactate expression: alac -> alac (reference; 111/1285, 8.9%), alac -> lac (28/1285, 2.2%), lac -> alac (259/1285, 20.2%), and lac -> lac (887/1285, 69.0%). Lac -> lac had a significantly higher 30-day mortality (OR = 2.058, 95% CI = [1.353–3.154]) compared to alac -> alac. Lac -> alac had a significantly increased LOS (OR = 1.133 (95% CI = [1.003–1.280]) compared to alac -> alac. Other group comparisons for 30-day mortality and LOS were not significant. Conclusion: Intubated sepsis and septic shock patients in the lac -> lac group had a …

It is presumed that this is due to limited exposure to rural EM scenarios throughout training, leading to hesitancy to practice in these situations as a new graduates with minimal single provider experience. Review of MedEd Portal demonstrates no curriculum filling this deficit in EM training, leading to the development of this curriculum. Purpose/Objective: The goal of the curriculum was to inspire further interest and preparedness to work in rural/critical access hospitals (CAHs). The hope was that …

Vesicant Infusates Are Not Associated With Ultrasound-Guided Peripheral Intravenous Catheter Failure: A Secondary Analysis Of Existing Data, Mahmoud Hijazi, Amit Bahl, Nai-Wei Chen

Posters

With over 300 million used annually in the United States, peripheral intravenous catheters (PIVC) are the most commonly used invasive device in the acute care setting1,2. Unfortunately, PIVCs have high failure rates with up to 63% failing prematurely3,4.

Certain intravenous medications categorized as vesicants and irritants are known to cause vein and local tissue injury. The Infusion Nursing Society (INS) created this list based on infusate osmolarity thresholds that increase the likelihood of these complications5.

It is perceived the impact of these medications on larger proximal veins with higher flow rates and improved hemodilution diminishes the likelihood of these complications. …

Rethinking Resilience Using The R-Factor: Neurobiological Mechanisms Of Static And Dynamic Components Of Resilience Following Trauma, Sanne Van Rooij, Justin Santos, Cecilia A. Hinojosa, Timothy Ely, Nathaniel Harnett, Vishnu P. Murty, Lauren Lebois, Tanja Jovanovic, Stacey House, Robert A. Swor

Articles

Resilience is a dynamic process of recovery after trauma, but in most studies it is conceptualized as the absence of specific psychopathology following trauma. Using the large emergency department AURORA study (n=1,865, 63% women), we took a longitudinal, dynamic and transdiagnostic approach to define a static resilience (r) factor, that could explain >50% of variance in mental wellbeing 6-months following trauma, and a dynamic r-factor, which represented recovery from initial symptoms. We assessed its neurobiological profile across threat, inhibition, and reward processes using fMRI collected 2-weeks post-trauma. Our neuroimaging results suggest that resilience is promoted by activation of higher-level cognitive …

Family/Decision Maker Perception Of Patient Care And Withdrawal Of Life Sustaining Treatment, Joshua Paul, Revelle Gappy, Tracy Wunderlich-Barillas, Robert A. Swor

Posters

Withdrawal of life sustaining treatment (WLST) is the process by which a patient has life supporting measures removed when a decision is reached that further care if futile. This process is a complex interplay of medical science, the healthcare teams’ past experiences, and communication with the patient’s family/decision maker Family members are commonly called upon to make critical decisions regarding the provision or withdrawal of patient care. Our objective was to describe the perceptions and experiences of the family members of patients who were admitted to an intensive care unit after resuscitation from an Out of Hospital Cardiac Arrest (OHCA).

Impact Of Earlier Ophthalmology Clerkships On Medical Student Match Rates In Ophthalmology, Andrew Lee, Steven Joseph

Posters

The purpose of this study is to analyze the association between earlier clerkship exposure and match success, specifically in ophthalmology. Medical schools are constantly changing their clinical curriculums to provide a stronger foundational education to their students. The structure of each medical school’s clerkship curriculum varies in timing, length and availability of certain core and elective rotations. Gaining a better understanding of the factors that affect student match rates in certain specialties can influence changes in clinical curricula to maximize future match success.
