A New Approach: Evaluating The Effectiveness Of Artificial Intelligence Developments For Trauma Triage In The Emergency Department, William C. Anoka

2025 Spring Honors Capstone Projects - Archive

Triage in emergent situations occurs when patients are assigned to areas of the hospital with different levels of care according to the perceived risks determined by their signs and symptoms. The variability of current triage protocols substantially increases the proportion of lower acuity patients who die unexpectedly due to improper risk stratification. However, recent artificial intelligence (AI) developments have been applied to trauma triage situations to improve accuracy and patient outcomes. To further evaluate the effectiveness of this new tool, this study used various AI models to assess the presenting assessments of multiple situations and determine the appropriate level of …

Hypothermia In Patients With Traumatic Injuries: An Integrative Review, Andrew P. Gribble, David J. Saucedo

Master's Projects

Abstract

Background: An estimated 30-50% of severely injured patients with traumatic injuries will experience hypothermia. As a result of hypothermia, several clinical manifestations such as impaired coagulation, dissociation of the oxygen curve, cardiac arrhythmias, reduced cardiac output and death. Little evidence has been published promoting specific patient re-warming protocols and the best rewarming methods, active versus passive. Few studies have focused on the pre-hospitalization treatment for hypothermia and the overall effectiveness of interventions to mitigate hypothermia to reduce morbidity and mortality. Given this knowledge, the aim of this integrative review (IR) is to research and evaluate current practices regarding hypothermia …

The Impact Of Chronic Comorbidities On Outcomes In Acute Exacerbations Of Idiopathic Pulmonary Fibrosis, Saqib H. Baig, Erika J. Yoo

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

INTRODUCTION: Idiopathic pulmonary fibrosis is a chronic progressive lung disease of unknown cause with a high associated mortality. We aimed to compare the impact of chronic medical conditions on hospital outcomes of patients with acute exacerbations of idiopathic pulmonary fibrosis (AE-IPF).

METHODS: This was a retrospective cohort study using the NIS database from 2016 to 2018. We included patients aged 60 and older hospitalized in academic medical centers with the diagnoses of IPF and acute respiratory failure. We examined factors associated with hospital mortality and length of stay (LOS) using survey-weighted multivariate logistic and negative binomial regression.

RESULTS: Out of …

Sex And Race Disparities In Mortality And Years Of Potential Life Lost Among People With Hiv: A 21-Year Observational Cohort Study, Noelle Best, Stephen Raffanti, Timothy R Sterling, Jessica L Castilho

Faculty, Staff and Student Publications

BACKGROUND: Since the availability of antiretroviral therapy, mortality rates among people with HIV (PWH) have decreased; however, this does not quantify premature deaths among PWH, and disparities persist.

METHODS: We examined all-cause and premature mortality among PWH receiving care at the Vanderbilt Comprehensive Care Clinic from January 1998 to December 2018. Mortality rates were compared by demographic and clinical factors, and adjusted incidence rate ratios (aIRRs) were calculated using multivariable Poisson regression. For individuals who died, age-adjusted years of potential life lost (aYPLL) per total person-years living with HIV were calculated from US sex-specific life tables, and sex and race …

INTRODUCTION: A rapid surge in cases during the COVID-19 pandemic can overwhelm any healthcare system. It is imperative to triage patients who would require oxygen and ICU care, and predict mortality. Specific parameters at admission may help in identifying them.

METHODOLOGY: A prospective observational study was undertaken in a COVID-19 ward of a tertiary care center. All baseline clinical and laboratory data were captured. Patients were followed till death or discharge. Univariable and multivariable logistic regression was used to find predictors of the need for oxygen, need for ICU care, and mortality. Objective scoring systems were developed for the same …

Comparison Of Different Metrics Of Cerebral Autoregulation In Association With Major Morbidity And Mortality After Cardiac Surgery, Brian Bush, Marek Czosnyka, Peter Smielewski, Charles H Brown

Faculty, Staff and Student Publications

BACKGROUND: Cardiac surgery studies have established the clinical relevance of personalised arterial blood pressure management based on cerebral autoregulation. However, variabilities exist in autoregulation evaluation. We compared the association of several cerebral autoregulation metrics, calculated using different methods, with outcomes after cardiac surgery.

METHODS: Autoregulation was measured during cardiac surgery in 240 patients. Mean flow index and cerebral oximetry index were calculated as Pearson's correlations between mean arterial pressure (MAP) and transcranial Doppler blood flow velocity or near-infrared spectroscopy signals. The lower limit of autoregulation and optimal mean arterial pressure were identified using mean flow index and cerebral oximetry index. …

Background: Illness predictive scoring systems are significant and meaningful adjuncts of patient management in the Intensive Care Unit (ICU). They assist in predicting patient outcomes, improve clinical decision making and provide insight into the effectiveness of care and management of patients while optimizing the use of hospital resources. We evaluated mortality predictive performance of Simplified Acute Physiology Score (SAPS 3) and Mortality Probability Models (MPM0-III) and compared their performance in predicting outcome as well as identifying disease pattern and factors associated with increased mortality.

Methods: This was a retrospective cohort study of adult patients admitted to the ICU of the …

Association Of New And/Or Progressive Multiple Organ Dysfunction Syndrome With Mortality And New Morbidity Among Children Encountering Septic Shock, Rachel L. Waworuntu

Capstone Experience: Master of Public Health

Despite reductions in sepsis mortality, there remains a substantial morbidity burden among children who survive sepsis. Furthermore, the majority develop multiple organ ‘group has historically been analyzed as a single cohort. Using the Life After Pediatric Sepsis Evaluation (LAPSE) investigation database, we studied the association of new and progressive multiple organ dysfunction syndrome (NPMODS) with morbidity and mortality among children with septic shock. We hypothesized that NPMODS represents a distinct phenotype based on evolving organ dysfunction. There was evidence of an association but it did not reach the 0.05 level of significance. We also hypothesized and confirmed that children with …

Barriers To Healthy Births At Nigerian Hospitals, Caroline Johnston

Senior Theses

Maternal mortality is a problem everywhere, but it is especially dangerous in Nigeria where the average woman experiences pregnancy six times during her lifetime (Population Reference Bureau, 2001). Many researchers focus on the medical complications associated with labor, such as hemorrhage, eclampsia, or infection. Although these birth complications are the direct sources of maternal death, it is also important to recognize how maternal mortality is a multifaceted issue influenced by local cultural groups, religions, politics, poverty level and the absence of basic infrastructures. Although maternal mortality is interconnected with social and geographical elements, my paper concentrates on Nigerian hospitals and …

Hokanson, Terri H Beaty, Elizabeth A. Regan, Stephen I. Rennard, Christina Wern, Michael R. Jacobs, Ruth Tal-Singer, Barry J. Make, Gregory L. Kinney, Copdgene Investigators

Journal Articles: Pulmonary & Critical Care Med

PURPOSE: Medication patterns include all medications in an individual's clinical profile. We aimed to identify chronic co-morbidity treatment patterns through medication use among COPDGene participants and determine whether these patterns were associated with mortality, acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and quality of life.

MATERIALS AND METHODS: Participants analyzed here completed Phase 1 (P1) and/or Phase 2 (P2) of COPDGene. Latent class analysis (LCA) was used to identify medication patterns and assign individuals into unobserved LCA classes. Mortality, AECOPD, and the St. George's Respiratory Questionnaire (SGRQ) health status were compared in different LCA classes through survival analysis, logistic …

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 …

The University of Louisville Journal of Respiratory Infections

Background: There exists a large body of literature to help identify, diagnose, treat, and manage community-acquired pneumonia (CAP). Despite this, there is little data that directly compares the clinical syndromes and complications of pure bacterial pneumonia to pure viral pneumonia. Our study compares the clinical presentation, morbidity and mortality of viral vs. bacterial etiologies of CAP.

Methods: This was a secondary data analysis of the Community-Acquired Pneumonia Organization (CAPO) international study database. Data was collected concerning patient demographics, physical examination findings, laboratory findings, radiological findings, severity of illness, and clinical outcomes and stratified according to the two study groups, CAVP …

It's More Than Low Bmi: Prevalence Of Cachexia And Associated Mortality In Copd, Merry-Lynn N. Mcdonald, Emiel F.M. Wouters, Erica Rutten, Richard Casaburi, Stephen I. Rennard, David A. Lomas, Marcas Bamman, Bartolome Celli, Alvar Agusti, Ruth Tal-Singer, Craig P. Hersh, Mark Dransfield, Edwin K. Silverman

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Cachexia is associated with increased mortality risk among chronic obstructive pulmonary disease (COPD) patients. However, low body mass index (BMI) as opposed to cachexia is often used, particularly when calculating the BODE (BMI, Obstruction, Dyspnea and Exercise) index. For this reason, we examined mortality using a consensus definition and a weight-loss definition of cachexia among COPD cases and compared two new COPD severity indices with BODE.

METHODS: In the current report, the consensus definition for cachexia incorporated weight-loss > 5% in 12-months or low BMI in addition to 3/5 of decreased muscle strength, fatigue, anorexia, low FFMI and inflammation. The …
