INTRODUCTION: Though early hypotension after pediatric in-hospital cardiac arrest (IHCA) is associated with inferior outcomes, ideal post-arrest blood pressure (BP) targets have not been established. We aimed to leverage prospectively collected BP data to explore the association of post-arrest BP thresholds with outcomes. We hypothesized that post-arrest systolic and diastolic BP thresholds would be higher than the currently recommended post-cardiopulmonary resuscitation BP targets and would be associated with higher rates of survival to hospital discharge.

METHODS: We performed a secondary analysis of prospectively collected BP data from the first 24 h following return of circulation from index IHCA events enrolled …

METHODS: We analyzed a convenience sample of patients with COVID-19 and moderate-to-severe ARDS, admitted to 244 intensive care units within the COVID-19 Critical Care Consortium, from February 1, 2020, through October 31, 2021. Patients undergoing at least 2 days and up to 3 consecutive days of NMBAs (NMBA treatment), within 48 …

Association Of Antinuclear Antibody Seropositivity With Inhaled Environmental Exposures In Patients With Interstitial Lung Disease, K. Biblowitz, Cathryn Lee, Daisy Zhu, Imre Noth, Rekha Vij, Mary E Strek, Shashi K Bellam, Ayodeji Adegunsoye

Division of Pulmonary and Critical Care Medicine Faculty Papers

Background: Interstitial lung diseases (ILDs) are diffuse parenchymal lung disorders that cause substantial morbidity and mortality. In patients with ILD, elevated antinuclear antibody (ANA) titres may be a sign of an autoimmune process. Inhalational exposures contribute to ILD pathogenesis and affect prognosis and may trigger autoimmune disease. The association of inhalational exposures with ANA seropositivity in ILD patients is unknown.

Methods: This was a retrospective cohort study of adult ILD patients from five centres in the United States. Exposures to tobacco, inhaled organic antigens and inhaled inorganic particles were extracted from medical records. A multivariable logistic regression model was used …

The spread of new coronavirus (SARS-Cov-2) follows a different pattern than previous respiratory viruses, posing a serious public health risk worldwide. World Health Organization (WHO) named the disease as COVID-19 and declared it a pandemic. COVID-19 is characterized by highly contagious nature, rapid transmission, swift clinical course, profound worldwide impact, and high mortality among critically ill patients. Chest X-ray, computerized tomography (CT), and ultrasound are commonly used imaging modalities. Among them, ultrasound, due to its portability and non-invasiveness, can be easily moved to the bedside for examination at any time. In addition, with use of 4G or 5G networks, remote …

Critical Care Ultrasonography And Its Application For Covid-19, Xi Liu, Md, Yang Hai, Md, Bin Ma, Md, Weelic Chong, Md, Ji-Bin Liu, Md

Department of Radiology Faculty Papers

Ultrasound has developed as an invaluable tool in diagnosis and proper management in the intensive care unit (ICU). Application of critical care ultrasonography is quite distinct from the routine comprehensive diagnostic ultrasound exam, because the urgent setting mandates a goal-directed approach. Performing accurate and efficient critical care ultrasound requires ultrasound providers to first understand the pathophysiology of the disease and related imaging findings, and then follow the protocols to perform a focused ultrasound exam. In the ongoing coronavirus disease 2019 (COVID-19) pandemic, ultrasound plays an essential role in diagnosing and monitoring critically ill COVID-19 patients in the ICU. Our review …

Characteristics And Outcomes Of Patients Directly Discharged To Home From The Intensive Care Unit, Ann Zheng, Preeyal M. Patel, Michele Fiorella, Lauren Mcdonnell, Mina Yasuoka, Erika J. Yoo, Md

Phase 1

Introduction: Given the current era of decreasing hospital bed availability, there has been a rise in the practice of direct discharge to home (DDH) from ICUs. We evaluated the demographics, clinical characteristics, outcomes and readmission patterns among DDH patients.

Methods: Retrospective review of patients from 2 MICUs from June 2017 to June 2019 at Thomas Jefferson University hospital, an urban tertiary care center. Primary outcome of interest was 30-day hospital readmission. Patients were dichotomized into two groups based on time between ward transfer order and hospital discharge (<24 or ≥24 hours). Risk adjustment performed with Mortality Probability Model (MPM0 -III). ICU workload at admission and discharge was estimated with nine equivalents of nursing manpower use score (NEMS). Patient characteristics compared using t-test and Fisher exact or χ² test.

Results: 331 DDH patients were analyzed, with the majority …

Bova Is Superior To Spesi In Identification Of High Risk Pulmonary Embolism Patients, J. Dibello, P. Khaing, E. Gupta, C. Au, T. Chengsupanimit, B. K. Awsare, M. Baram, F. M. West, G. C. Kane

Phase 1

Introduction: Prognostic models exist for the purpose of stratifying patients with acute pulmonary embolism. Of these, the Pulmonary Embolism Severity Index (PESI) and the simplified PESI (sPESI) are the most well-known, although more recent composite models, like the BOVA score, are now being studied and implemented. Comparative efficacy of these scores to predict long term mortality is not well established.

Methods: We performed a retrospective analysis of all consecutive patients diagnosed with PE using computed tomography scan from 2014-2016 at an urban tertiary-referral medical center. Cox proportional hazard analyses were performed to compare the performance of two prognostic …

Implementation Of Attending-Supervised Ipass Handoff In The Neuro-Icu, Laura Cifrese, Md, Sonia Gill, Md, Megan Margiotta, Md, Muhammad Athar, Md, Rodney Bell, Md, Sara Hefton, Md, Fred Rincon, Md, Msc, Mbe, Syed Shah, Md, Mba, Jacqueline Urtecho, Md, Matthew Vibbert, Md, David Wyler, Md, Amandeep Dolla, Md

House Staff Quality Improvement and Patient Safety Conference (2016-2019)

Background

• Duty hour restrictions, cross coverage, and the growing number of mid-level practitioners has led to an increased number of handoffs across medical specialties
• These handoffs are well-known points of communication breakdown which can lead to patient safety issues
• Factors contributing to an effective handoff include standardization of communication, appropriate training and supervision, ample time, a quiet environment, and a supportive culture
• We hypothesize that attending supervision of handoffs is feasible and can improve practitioner perception of transitions of care

A Rare Case Of Diffuse Alveolar Hemorrhage Secondary To Dabigatran Successfully Treated With Extracorporeal Membrane Oxygenation, C. Hutchinson, F. M. West, H. Hirose

Department of Medicine Posters

Introduction

Dabigatran, a direct thrombin inhibitor, is used for stroke risk reduction in non-valvular atrial fibrillation and for treatment and prevention of venous thromboembolism. Minor side effects include indigestion and stomach pain. Major life threatening bleeding occurs in up to 2% of patients and is largely attributed to gastrointestinal hemorrhage. Here, we describe a case of a dabigatran related diffuse alveolar hemorrhage (DAH) treated successfully with extracorporeal membrane oxygenation.

Intermediate-Term Risk Of Stroke Following Cardiac Procedures In A Nationally Representative Data Set., Laura Stein, Alison Thaler, John W. Liang, Stanley Tuhrim, Amit S. Dhamoon, Mandip S. Dhamoon

Department of Neurology Faculty Papers

BACKGROUND: Studies on stroke risk following cardiac procedures addressed only perioperative and long-term risk following limited higher-risk procedures, were poorly generalizable, and often failed to stratify by stroke type. We calculated stroke risk in the intermediate risk period following cardiac procedures compared with common noncardiac surgeries and medical admissions.

METHODS AND RESULTS: The Nationwide Readmissions Database contains readmission data for 49% of US admissions in 2013. We compared age-adjusted stroke readmission rates up to 90 days postdischarge. We used Cox regression to calculate hazard ratios, up to 1 year, of stroke risk comparing transcatheter aortic valve replacement versus surgical aortic …

Caveolae are cell membrane invaginations that are highly abundant in adipose tissue, endothelial cells and the lung. The formation of caveolae is dependent on the expression of various structural proteins that serve as scaffolding for these membrane invaginations. Cavin1 is a newly identified structural protein whose deficiency in mice leads to loss of caveolae formation and to development of a lipodystrophic phenotype. In this study, we sought to investigate the functional role of Cavin1 in the lung. Cavin1 deficient mice possessed dramatically altered distal lung morphology and exhibited significant physiological alterations, notably, increased lung elastance. The changes in distal lung …
