A Risk Score For Identifying Methicillin-Resistant Staphylococcus Aureus In Patients Presenting To The Hospital With Pneumonia., Andrew F. Shorr, Daniela E. Myers, David B. Huang, Brian H. Nathanson, Matthew F. Emons, Marin H. Kollef

Emergency Medicine Faculty Publications

Background

Methicillin-resistant Staphylococcus aureus (MRSA) represents an important pathogen in healthcare-associated pneumonia (HCAP). The concept of HCAP, though, may not perform well as a screening test for MRSA and can lead to overuse of antibiotics. We developed a risk score to identify patients presenting to the hospital with pneumonia unlikely to have MRSA.

Methods

We identified patients admitted with pneumonia (Apr 2005 – Mar 2009) at 62 hospitals in the US. We only included patients with lab evidence of bacterial infection (e.g., positive respiratory secretions, blood, or pleural cultures or urinary antigen testing). We determined variables independently associated with the …

Emergency Medicine Faculty Publications

Introduction: In emergency department (ED) patients with upper abdominal pain, management includes ruling out serious diseases and providing symptomatic relief. One of the major causes of upper abdominal pain is an ulcer caused by Helicobacter pylori (H. pylori), which can be treated and cured with antibiotics. We sought to estimate the prevalence of H. pylori infection in symptomatic patients using a convenience sample at a single urban academic ED and demonstrate the feasibility of ED-based testing.

Methods: We prospectively enrolled patients with a chief complaint of pain or discomfort in the upper abdomen for 1 year from February …

Sickle Cell Disease: A Quality Improvement Initiative For Emergency Department Providers, Pretrescia Marie Walker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sickle Cell Disease (SCD) is an incurable, chronic condition that results in a constellation of disorders, frequent emergency department (ED) visits, and repeated hospital admissions. Those affected often suffer from pain crisis, infection, acute chest syndrome, stroke, and multi-organ impairment and frequently do not receive adequate pain management during acute pain episodes because ED providers view them as drug seeking. The majority of patients with SCD are African-American and may be low income, uninsured, or on Medicaid. As a result, these demographics make ED under-treatment of pain in patients with SCD a health equity issue. This was a pre-experimental one …

Patient-Driven Resource Planning Of A Health Care Facility Evacuation, Bruno P. Petinaux, Kabir Yadav

Emergency Medicine Faculty Publications

Introduction: The evacuation of a health care facility is a complex undertaking, especially if done in an immediate fashion, ie, within minutes. Patient factors, such as continuous medical care needs, mobility, and comprehension, will affect the efficiency of the evacuation and translate into evacuation resource needs. Prior evacuation resource estimates are 30 years old.

Methods: Utilizing a cross-sectional survey of charge nurses of the clinical units in an urban, academic, adult trauma health care facility (HCF), the evacuation needs of hospitalized patients were assessed periodically over a two-year period.

Results: Survey data were collected on 2,050 patients. Units with patients …

Prevalence And Risk Factor Analysis Of Resistant Escherichia Coli Urinary Tract Infections In The Emergency Department, Abby M. Bailey, Kyle A. Weant, Stephanie N. Baker

Emergency Medicine Faculty Publications

BACKGROUND: Escherichia coli (E. coli) is a frequent uropathogen in urinary tract infections (UTI). Widespread resistance to sulfamethoxazole-trimethoprim (SMX-TMP) and increasing resistance to fluoroquinolones amongst these isolates has been recognized. There are limited data demonstrating risk factors for resistance to both SMX-TMP and fluoroquinolones.

OBJECTIVE: This study was conducted to assess for the prevalence of community resistance amongst E. coli isolates to SMX-TMP and levofloxacin in ambulatory patients discharged from the emergency department (ED).

Major Incidents In Kenya: The Case For Emergency Services Development And Training, Benjamin Wachira, Wayne Smith

Internal Medicine, East Africa

Kenya's major incidents profile is dominated by droughts, floods, fires, terrorism, poisoning, collapsed buildings, accidents in the transport sector and disease/epidemics. With no integrated emergency services and a lack of resources, many incidents in Kenya escalate to such an extent that they become major incidents. Lack of specific training of emergency services personnel to respond to major incidents, poor coordination of major incident management activities, and a lack of standard operational procedures and emergency operation plans have all been shown to expose victims to increased morbidity and mortality. This report provides a review of some of the major incidents in …

Utilizing our previously developed information dissemination tools and a hazard assessment checklist tailored to a low-income neighborhood in Pakistan, we pilot tested and compared the effectiveness of two dissemination tools.

Methods: Two low-income neighborhoods were mapped, identifying families with a child aged between 12 and 59 months. In June and July 2010, all enrolled households underwent a home hazard assessment at the same time hazard reduction education was being given using an in-home tutorial or a pamphlet. …

Lymphotoxin-Α Is A Novel Adiponectin Expression Suppressor Following Myocardial Ischemia/Reperfusion., Wayne Bond Lau, Yanqing Zhang, Jianli Zhao, Baojiang Liu, Xiaoliang Wang, Yuexing Yuan, Theodore A. Christopher, Bernard Lopez, Erhe Gao, Walter J. Koch, Xin L. Ma, Yajing Wang

Department of Emergency Medicine Faculty Papers

Recent clinical observations demonstrate adiponectin (APN), an adipocytokine with potent cardioprotective actions, is significantly reduced following myocardial ischemia/reperfusion (MI/R). However, mechanisms responsible for MI/R-induced hypoadiponectinemia remain incompletely understood. Adult male mice were subjected to 30-min MI followed by varying reperfusion periods. Adipocyte APN mRNA and protein expression and plasma APN and TNFα concentrations were determined. APN expression/production began to decline 3 h after reperfusion (reaching nadir 12 h after reperfusion), returning to control levels 7 days after reperfusion. Plasma TNFα levels began to increase 1 h after reperfusion, peaking at 3 h and returning to control levels 24 h after …

Pathogen-Specific Risk Of Chronic Gastrointestinal Disorders Following Bacterial Causes Of Foodborne Illness, Chad K. Porter, Daniel Choi, Brooks Cash, Mark Pimentel, Joseph Murray, Larissa May, Mark S. Riddle

Emergency Medicine Faculty Publications

Background

The US CDC estimates over 2 million foodborne illnesses are annually caused by 4 major enteropathogens: non-typhoid Salmonella spp., Campylobacter spp., Shigella spp. and Yersinia enterocoltica. While data suggest a number of costly and morbid chronic sequelae associated with these infections, pathogen-specific risk estimates are lacking. We utilized a US Department of Defense medical encounter database to evaluate the risk of several gastrointestinal disorders following select foodborne infections.

Methods

We identified subjects with acute gastroenteritis between 1998 to 2009 attributed to Salmonella(nontyphoidal) spp., Shigella spp., Campylobacter spp. or Yersinia enterocolitica and matched each with up to 4 …

The objective of our study was to compare emergency department (ED) outcomes of the school-based injuries with respect to age, sex, and injury mechanisms in a Pakistani urban setting.

Findings

A pilot injury surveillance study was conducted at the EDs of three major tertiary-care hospitals of Rawalpindi city from July 2007 to June 2008 and included children of less than 15 years injured at school. The World Health Organization’s questionnaire for injury surveillance was used. There were …

Broadening Access To Medical Care During A Severe Influenza Pandemic: The Cdc Nurse Triage Line Project., Lisa M. Koonin, Dan Hanfling

Emergency Medicine Faculty Publications

The impact of a severe influenza pandemic could be overwhelming to hospital emergency departments, clinics, and medical offices if large numbers of ill people were to simultaneously seek care. While current planning guidance to reduce surge on hospitals and other medical facilities during a pandemic largely focuses on improving the “supply” of medical care services, attention on reducing “demand” for such services is needed by better matching patient needs with alternative types and sites of care. Based on lessons learned during the 2009 H1N1 pandemic, the Centers for Disease Control and Prevention and its partners are currently exploring the acceptability …

Nitric Oxide And Its Metabolites In The Critical Phase Of Illness: Rapid Biomarkers In The Making, Asad Mian, Mayank Aranke, Nathan S. Bryan

Department of Emergency Medicine

The potential of nitric oxide (NO) as a rapid assay biomarker, one that could provide a quantum leap in acute care, remains largely untapped. NO plays a crucial role as bronchodilator, vasodilator and inflammatory mediator. The main objective of this review is to demonstrate how NO is a molecule of heavy interest in various acute disease states along the emergency department and critical care spectrum: respiratory infections, central nervous system infections, asthma, acute kidney injury, sepsis, septic shock, and myocardial ischemia, to name just a few. We discuss how NO and its oxidative metabolites, nitrite and nitrate, are readily detectable …

The Treatment Of Cutaneous Abscesses: Comparison Of Emergency Medicine Providers' Practice Patterns, Gillian Schmitz, Tress Goodwin, Adam Singer, Chad S. Kessler, David Bruner, Hollyn Larabee, Larissa S. May, Samuel D. Luber, Justin Williams, Rahul Bhat

Emergency Medicine Faculty Publications

INTRODUCTION:

Cutaneous abscesses are commonly treated in the emergency department (ED). Although incision and drainage (I&D) remains the standard treatment, there is little high-quality evidence to support additional interventions such as pain control, type of incision, and use of irrigation, wound cultures, and packing. Although guidelines exist to support clinician management of abscesses, they do not clearly specify these additional interventions. This study sought to describe the ED treatments administered to adults with uncomplicated superficial cutaneous abscesses, defined as purulent lesions requiring incision and drainage that could be managed in an ED or outpatient setting.

METHODS:

Four hundred and seventy-four …

Perceptions Of Emergency Department Crowding In The Commonwealth Of Pennsylvania, Jesse M. Pines, Joshua A. Isserman, John J. Kelly

Emergency Medicine Faculty Publications

Introduction: The state of emergency department (ED) crowding in Pennsylvania has not previously been reported.

Methods: We assessed perceptions of ED crowding by surveying medical directors/chairs from Pennsylvania EDs in the spring of 2008.

Results: A total of 106 completed the questionnaire (68% response rate). A total of 83% (86/104) agreed that ED crowding was a problem; 26% (27/105) reported that at least half of admitted patients boarded for more than 4 hours. Ninety-eight percent (102/104) agreed that patient satisfaction suffers during crowding and 79% (84/106) stated that quality suffers. Sixty-five percent (68/105) reported that crowding had worsened during the …

Tension Pneumothorax, Pneumoperitoneum, And Cervical Emphysema Following A Diagnostic Colonoscopy, Ali Pourmand, Hamid A. Shokoohi

Emergency Medicine Faculty Publications

Colonoscopy is currently a widespread procedure used in screening for colorectal cancer. Iatrogenic colonic perforation during colonoscopy is a serious and potentially life-threatening complication that can cause significant morbidity and mortality. “Triple pneumo” (a combination of pneumothorax, pneumomediastinum, and pneumoperitoneum) following colonoscopy is a rare but a serious condition requiring immediate diagnosis and emergent intervention. In majority of these cases a colonic perforation is the initial injury that is followed by pneumothorax and pneumomediastinum through the potential anatomical connection with retroperitoneal and mediastinal spaces. In this rare case report we are presenting a case of “triple pneumo” with no evidence …

Impacts Of Social Networking Sites On Patient Care In The Emergency Department, Anne Bennett, Ali Pourmand, Robert Shesser, Jesus Sanchez, Joseph Joyce

Emergency Medicine Faculty Publications

The use of Facebook is ubiquitous among both patients and physicians. Often Facebook intrudes into medical practice, thereby highlighting its potential to be either a positive or negative factor in a patient's medical care. Despite being a “hot topic” in the medical literature, very few real world examples exist of physicians actually using information obtained from Facebook to reach a diagnosis or otherwise affect patient care. We present a case involving a 13-year-old girl who posted photographs and captions on Facebook demonstrating suicidal ideation. The patient's parents were alerted to the girl's statements in her Facebook profile and brought her …
