Making Diagnostic Uncertainty Visible At Intensive Care Unit Transitions: A Narrative Review Of Diagnostic Pause Strategies, Raha West, Ahmed Elhaddad, Behrad Baharlo, Parind Patel

HCA Healthcare Journal of Medicine

Background

Diagnostic error is a significant patient safety issue in critical care. However, it is often difficult to detect during ongoing care. Patients in the Intensive Care Unit (ICU) often have incomplete histories, overlapping symptoms, changing physiology, and concurrent issues. During ICU transitions, patient diagnoses are often reported without clear information on diagnostic confidence, potential alternative diagnoses, pending results, or triggers needing review.

Methods

This clinical narrative review explored diagnostic uncertainty at ICU transitions, specifically those during ICU-to-ward transfers or unplanned escalations to the ICU. A targeted literature search identified studies of adult ICU diagnostic errors, ICU transition safety, ICU-PAUSE …

Beyond Bed Numbers: A Proposed Quality Improvement Framework For Reviewing Icu Acuity, Workload, And Medical Staffing, Raha West, Ahmed Elhaddad, Behrad Baharlo, Parind Patel

HCA Healthcare Journal of Medicine

Background

Intensive care unit (ICU) medical staffing is often planned using bed numbers or fixed ratios. These counts do not describe the work required when patients deteriorate, urgent tasks overlap, or clinicians have duties outside the unit. A structured review could help teams discuss whether available cover can meet these demands.

Methods

We undertook a targeted narrative synthesis of adult ICU staffing guidance, acuity and workload measures, physician workload studies, and capacity-strain research available through 8 September 2026. We examined study settings, findings, and limitations to inform the framework domains. The authors proposed the review prompts and response options. No …

Life After Ecmo: A Comprehensive Review Of Longterm Complications, Mia Olson Pa-C

Lynchburg Journal of Medical Science

Extracorporeal life support is the ability to temporarily supplement pulmonary and/or cardiac function in the setting of severe organ failure, with the most widely used version of this technology being extracorporeal membrane oxygenation (ECMO). While ECMO acutely improves outcomes in many patients with acute cardiopulmonary failure, evidence shows that survivors are at risk for long-term complications. These may include physical limitations, neurocognitive impairment, and psychological distress, all of which cumulate to impact a patient’s quality of life. The purpose of this research paper is to examine the literature on long-term complications associated with ECMO therapy and their impact on patient …

Sedation Minimization And Early Mobility To Prevent Intensive Care Unit Delirium, Alana M. Kugelard

Lynchburg Journal of Medical Science

The purpose of this paper is to synthesize current evidence on sedation minimization, early mobility, and multicomponent care bundles for the prevention of intensive care unit (ICU) delirium in critically ill adults. ICU delirium is a common and serious complication associated with increased mortality, prolonged mechanical ventilation, extended ICU and hospital length of stay, and long-term cognitive impairment, making it a significant safety and quality-of-care concern. A literature review was conducted using PubMed and the Cochrane Library, with search terms including “ICU delirium,” “sedation minimization,” “light sedation,” “early mobilization,” and “ABCDEF bundle.” Filters included adult populations, peer-reviewed studies, randomized controlled …

Manuscripts, Articles, Book Chapters and Other Papers

Posaconazole is a triazole antifungal agent used for prophylaxis and treatment of invasive fungal diseases. Posaconazole has high inter-individual variability in dose-exposure relationship and benefits from therapeutic drug monitoring (TDM). Adult studies report particularly high rates of subtherapeutic exposure among intensive care unit (ICU) patients related to changes in physiology during critical illness. The rates of subtherapeutic posaconazole exposure among critically ill children in ICU's are unknown. This single-center retrospective analysis at a large freestanding children's hospital used TDM results from 2010 to 2025 obtained while patients were undergoing care in a pediatric ICU. Therapeutic targets were ≥ 1.0 mg/L …

Beyond Drainage: Can Pleural Effusion Naturally Tamponade Tumor Hemorrhage? Literature Review Of Hypotheses For Possible Mechanisms, Pratyush Kumar, Kumar Abhishek, Pankti Shah, Amelia Goslin, Archana Machavarapu, Catherine Joyce, Michael J. Waxman, Kari Nilsen

HCA Healthcare Journal of Medicine

Background

Malignant pleural effusion (MPE) is a common complication of advanced lung cancer and is typically treated with therapeutic drainage to relieve symptoms. Although this is a well-established palliative approach, removing pleural fluid—especially in cases of necrotic or post-radiation tumors—may disturb the fragile pressure balance within the thoracic cavity. The question of whether pleural effusion can act as a natural tamponade against tumor-related vascular fragility has not been thoroughly investigated.

Case Presentation

We report a case of a 49-year-old man with stage IIIB non–small cell lung cancer (NSCLC) who experienced a catastrophic hemorrhage shortly after pleural fluid removal via a …

Leveraging Administrative Health Data To Capture Rare Adverse Drug Reactions: Identifying Pediatric Patients With Trimethoprim-Sulfamethoxazole Acute Respiratory Distress Syndrome., Keith Feldman, Jenna Miller, Katherine Doane, Laura Loftis, James W. Antoon, Kevin J. Downes, Jennifer Goldman

Manuscripts, Articles, Book Chapters and Other Papers

Rare adverse drug reactions (ADRs) are underrecognized and underreported in the electronic medical record (EMR). These events often require clinical review, making systematic identification challenging. The study aim was to develop an approach to prioritize identification and validation of a rare ADR to trimethoprim-sulfamethoxazole causing acute respiratory distress syndrome (TMP-SMX ARDS) across medical institutions. We developed a clinical phenotype based on 2 local TMP-SMX ARDS cases mapped to standardized elements of a national comparative healthcare database (PHIS). We validated identification of TMP-SMX ARDS at scale across medical institutions. A set of scoring criteria was created to prioritize cases and generate …

Extracorporeal Rescue In Massive Pulmonary Embolism: A Case Of Chronic Thromboembolic Pulmonary Hypertension Unveiled, Kenzo Ramos, Kari Gorder

Journal of Shock and Hemodynamics

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare yet curable cause of pulmonary hypertension from unresolved pulmonary emboli. We present the case of a 48-year-old man with progressive dyspnea and leg swelling, who was found to have bilateral pulmonary emboli with right heart strain. He developed cardiac arrest during thrombectomy, requiring emergent veno-arterial extracorporeal membrane oxygenation (V-A ECMO). Further evaluation revealed acute emboli superimposed on CTEPH. After incomplete thrombectomy and persistent instability, he underwent successful pulmonary endarterectomy with ECMO decannulation, leading to recovery of right ventricular function and discharge in stable condition. This case illustrates that previously unrecognized CTEPH may …

Jain, Dalia A. Bashir, Stuart H. Friess, Brian M. Varisco, Jocelyn Grunwell, Aline B. Maddux, Stephen T. Famularo, Nadir Yehya

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Hyper-inflammation is common to multiple critical care syndromes, including acute respiratory distress syndrome (ARDS) and sepsis, and is associated with worse outcomes. A signature of hyper-inflammatory ARDS has been described in adults using IL-6, TNFR1, and bicarbonate, and has prognostic utility. We investigated the application of this traditional parsimonious signature to pediatric ARDS patients and tested whether we could improve prognostic enrichment using other cytokines.

METHODS: We leveraged a prospective multicenter cohort study of 500 children with ARDS (Linking Endotypes and Outcomes in Pediatric Acute Respiratory Distress Syndrome [LEOPARDS]; NCT04113434) study. Plasma samples were obtained within 24 h of …

Richmond Agitation-Sedation Scoring Implementation In A Critical Access Hospital, Jasmine A. Hobbs

Doctor of Nursing Practice Posters and Presentations

Mechanically ventilated patients who are boarding in rural emergency departments face an increased risk of inconsistent sedation management due to the lack of standardized protocols and the extended transfer times to higher levels of care. The variability in sedation practices can lead to both under- and over-sedation, which negatively affects patient comfort, safety, and clinical outcomes. Research suggests that sedation protocols incorporating the Richmond Agitation-Sedation Scale (RASS) can shorten mechanical ventilation duration and improve clinical outcomes. The purpose of this project was to evaluate the effectiveness of a targeted educational intervention on improving nursing knowledge and comfort with the RASS …

This case report underscores the critical interplay between adrenal crisis and seizure activity, emphasizing the importance of rapid recognition and management of this life-threatening condition. Adrenal crisis, characterized by severe hypotension and electrolyte disturbances, often manifests with nonspecific symptoms such as fatigue, nausea, and altered consciousness, which can obscure diagnosis, especially in pediatric and young adult populations. The report details a 21-year-old female with a complex endocrinologic background who developed seizures precipitated by an adrenal crisis triggered by gastroenteritis and compounded by medication noncompliance. Clinical findings included profound dehydration, electrolyte abnormalities, refractory hypotension, and low cortisol levels, which responded favorably …

Evaluation Of The Effectiveness Of Antihypertensive Therapy Chosen Through Maternal Hemodynamic Profile Analysis, Margaret Weimer

Poster Presentations

In treatment of emergent hypertension, the American College of Obstetricians and Gynecologists (ACOG) recommends both oral labetalol and nifedipine, with no preference shown between the two. These medications have different mechanisms of action. Studies have suggested that consideration of hemodynamic profile may be an effective way to determine medication, but have not considered the Rule of 55, a simple calculation to predict hemodynamic profile.

Goals: 1. Determine if tailoring the antihypertensive to patient’s hemodynamic profile is associated with better control of blood pressure. 2. Determine if the Rule of 55 is an accurate method to determine hemodynamic profile.

Navigating The Nicu Without Words: A Case Study Of A Spanish-Speaking Mother’S Healthcare Experience, Emma Norris

Poster Presentations

Research on NICU experiences largely focuses on majority-language families; non-English-speaking families are understudied (Cleveland, 2008). The Family Integrated Care model promotes parent-infant connection and shared decision-making to improve outcomes (Wreesmann et al., 2020). Language barriers impede parent-provider communication, increasing miscommunication and parental anxiety (Kynoe et al., 2020; Ardal et al., 2011). The purpose of this research is to explore communication experiences and barriers between English-speaking and bilingual NICU nurses and a Spanish-speaking NICU mother.

Adhesion Of Antibiotic-Resistant Bacteria To Thermoplastic Materials Used In Fabricating Medical Devices: Patient Consequences, Dev V. Mehta

Poster Presentations

Burn injury patients wear supportive orthoses made by heat-forming sheets of thermoplastic material (Figs. 1 & 2). Bacteria cause severe soft tissue infections in patients wearing contaminated orthoses. Thermoplastic medical devices can develop biofilms that include antibiotic-resistant (AR) bacteria, which significantly reduces the number of available treatment options. A biofilm is a community of microorganisms that share resources allowing them to exist in a nutrient-limited environment. Biofilm microbes secrete extracellular polymeric substance (EPS) that attaches them firmly to a substrate surface while protecting them from harmful substances, including antibiotics. Bacteria living within biofilms on inanimate surfaces can survive for extended …

Rethinking Mixed Dka-Hhs: An Extreme Presentation Of Hyperosmolar Hyperglycemic State, Sajith Silva, Umair Malik, Amin Pasha, Sujata Kambhatla

Conference Presentation Abstracts

Introduction: The American Diabetes Association (ADA) recognizes diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) as life-threatening hyperglycemic emergencies that can overlap clinically; approximately 10% of presentations are described as mixed DKA–HHS. Because current guidelines do not define a single “mixed” category, overlap is best understood as concurrent fulfillment of key elements of both syndromes: DKA-type anion-gap metabolic acidosis with ketonemia or ketonuria, together with HHS-type severe hyperglycemia, hyperosmolality, and dehydration. We report an extreme HHS presentation (glucose >2,100 mg/dL) with limited DKA overlap. Case Description: A 34-year-old woman with longstanding type 1 diabetes mellitus managed with an insulin pump, …
