The most impactful endometriosis symptom: An international, cross-sectional, two-round survey study.

Introduction: There is considerable variation in the types of symptoms experienced by people living with endometriosis, and it is unclear which symptoms impact people the most. This study aimed to identify the specific symptoms that are "most impactful" to people living with the condition.

Material And Methods: Two sequential online surveys were conducted.

Implementation of a compulsory clinical pharmacist-led medication deprescribing intervention in high-risk seniors in the emergency department.

Objectives: The objective of this study was to assess the impact of an emergency department (ED) deprescribing intervention for geriatric adults. We hypothesized that pharmacist-led medication reconciliation for at-risk aging patients would increase the 60-day case rate of primary care provider (PCP) deprescribing of potentially inappropriate medications (PIMs).

Methods: This was a retrospective, before-and-after intervention pilot study conducted at an urban Veterans Affairs ED.

A clinical decision framework to guide the outpatient treatment of emergency department patients diagnosed with acute pulmonary embolism or deep vein thrombosis: Results from a multidisciplinary consensus panel.

The outpatient treatment of select emergency department patients with acute pulmonary embolism (PE) or deep vein thrombosis (DVT) has been shown to be safe, cost effective and associated with high patient satisfaction. Despite this, outpatient PE and DVT treatment remains uncommon. To address this, the American College of Emergency Physicians assembled a multidisciplinary team of content experts to provide evidence-based recommendations and practical advice to help clinicians safely treat patients with low-risk PE and DVT without hospitalization.

Health seeking behaviours and treatments received by Australian women with vulvodynia: A cross-sectional survey.

Background: Vulvodynia is a condition characterised by pain in the vulva lasting more than three months and for which no obvious aetiology can be found. It affects around 8% of women and has significant negative impacts on quality of life. There is a paucity of research on healthcare management pathways and the use of evidence-based treatments in an Australian community setting.

Emergency Department Utilization in Children <36 Months Is Not an Independent Risk Factor for Maltreatment.

Background And Objectives: Early childhood high-frequency use (HFU) of the emergency department (ED) has been endorsed as a marker for increased risk of child maltreatment. In a prior analysis of pediatric ED (PED) visits by 16,664 children, 0-36 months old, we defined early childhood HFU (the 90th percentile) as five or more visits. The purpose of this study was to follow HFU patients to determine if they had a higher likelihood of reported maltreatment.

Major Adverse Events One Year After Acute Kidney Injury After Contrast-Enhanced Computed Tomography.

Study Objective: Recent studies have demonstrated that a single episode of acute kidney injury from a number of causes can increase the risk of severe long-term outcomes, including major cardiovascular events and death. We tested the hypothesis that patients who develop acute kidney injury consistent with contrast-induced nephropathy after contrast-enhanced computed tomography (CT) imaging are at increased risk of major adverse events at 1 year.

Methods: We followed a prospective, heterogeneous cohort of consecutive emergency department patients undergoing contrast-enhanced CT for the outcomes of acute kidney injury consistent with contrast-induced nephropathy and major adverse events, defined as the combined outcome of death (all cause), renal failure, myocardial infarction, and stroke or other arterial vascular events, in any anatomic territory, requiring invention within 1 year.

Cost-effectiveness of quantitative pretest probability intended to reduce unnecessary medical radiation exposure in emergency department patients with chest pain and dyspnea.

Objectives: Quantitative pretest probability (qPTP) incorporated into a decision support tool with advice can reduce unnecessary diagnostic testing among patients with symptoms suggestive of acute coronary syndrome (ACS) and pulmonary embolism (PE), reducing 30-day costs without an increase in 90-day adverse outcomes. This study estimates long-term (beyond 90-day) costs and outcomes associated with qPTP. The authors hypothesized that qPTP reduces lifetime costs and improves outcomes in low-risk patients with symptoms suggestive of ACS and PE.

Research priorities for the influence of gender on diagnostic imaging choices in the emergency department setting.

Diagnostic imaging is a cornerstone of patient evaluation in the acute care setting, but little effort has been devoted to understanding the appropriate influence of sex and gender on imaging choices. This article provides background on this issue and a description of the working group and consensus findings reached during the diagnostic imaging breakout session at the 2014 Academic Emergency Medicine consensus conference "Gender-specific Research in Emergency Care: Investigate, Understand, and Translate How Gender Affects Patient Outcomes." Our goal was to determine research priorities for how sex and gender may (or should) affect imaging choices in the acute care setting.

N-acetylcysteine plus intravenous fluids versus intravenous fluids alone to prevent contrast-induced nephropathy in emergency computed tomography.

Study Objective: We test the hypothesis that N-acetylcysteine plus normal saline solution is more effective than normal saline solution alone in the prevention of contrast-induced nephropathy.

Methods: The design was a randomized, double blind, 2-center, placebo-controlled interventional trial. Inclusion criteria were patients undergoing chest, abdominal, or pelvic computed tomography (CT) scan with intravenous contrast, older than 18 years, and at least one contrast-induced nephropathy risk factor.

Prospective study of the incidence of contrast-induced nephropathy among patients evaluated for pulmonary embolism by contrast-enhanced computed tomography.

Objectives: Contrast-enhanced computed tomography (CECT) of the pulmonary arteries (CTPA) has become the mainstay to evaluate patients with suspected pulmonary embolism (PE) and is one of the most common CECT imaging studies performed in the emergency department (ED). While contrast-induced nephropathy (CIN) is a known complication, this risk is not well defined in the ED or other ambulatory setting. The aim of this study was to define the risk of CIN following CTPA.

Immediate complications of intravenous contrast for computed tomography imaging in the outpatient setting are rare.

Objectives: Despite increasing attention to the long-term risks of radiation exposure and contrast-induced nephropathy (CIN), institutional guidelines and patient consent procedures for contrast-enhanced computed tomography (CECT) imaging in the emergency department (ED) setting have focused primarily on more immediate complications, directly attributable to the administration of intravenous (IV) iodinated contrast administration. Thus, this study sought to define the risk of these immediate complications with the overall aim of improving institutional guidelines and patient consent procedures.

Methods: This was a prospective, consecutive cohort study of patients undergoing CECT of any body region in the ED, for complications occurring within 1 week of contrast administration, using predefined implicit definitions.

Incidence of contrast-induced nephropathy after contrast-enhanced computed tomography in the outpatient setting.

Background And Objectives: No prospective study has reported the incidence of contrast-induced nephropathy (CIN) or the associated morbidity and mortality after contrast-enhanced computed tomography (CECT) in the outpatient setting.

Design, Setting, Participants, & Measurements: We enrolled and followed a prospective, consecutive cohort (June 2007 through January 2009) of patients who received intravenous contrast for CECT in the emergency department of a large, academic, tertiary care center. Outcomes measured were as follows (1) CIN: An increase in serum creatinine > or =0.

Direct comparison of the diagnostic accuracy of fifty protein biological markers of pulmonary embolism for use in the emergency department.

Objectives: Pulmonary embolism (PE) is associated with abnormal concentrations of many proteins involved in inflammation, hemostasis, and vascular injury. The authors quantified the diagnostic accuracy of a battery of protein biological markers for the detection of PE in emergency department (ED) patients.

Methods: A random and a consecutive sample of ED patients evaluated for PE were prospectively enrolled at two academic EDs between August 2005 and April 2006.

Tandem measurement of D-dimer and myeloperoxidase or C-reactive protein to effectively screen for pulmonary embolism in the emergency department.

Objectives: The hypothesis was that the tandem measurement of D-dimer and myeloperoxidase (MPO) or C-reactive protein (CRP) could significantly decrease unnecessary pulmonary vascular imaging in emergency department (ED) patients evaluated for pulmonary embolism (PE) compared to D-dimer alone.

Methods: The authors measured the sequential combinations of D-dimer and MPO and D-dimer and CRP in a prospective sample of ED patients evaluated for PE at two centers. Patients were followed for 90 days for venous thromboembolism (VTE, either PE or deep venous thrombosis [DVT]), which required the consensus of two of three blinded physician reviewers.

Emergency clinician-performed compression ultrasonography for deep venous thrombosis of the lower extremity.

Study Objective: Emergency clinician-performed ultrasonography holds promise as a rapid and accurate method to diagnose and exclude deep venous thrombosis. However, the diagnostic accuracy of emergency clinician-performed ultrasonography performed by a heterogenous group of clinicians remains undefined.

Methods: Prospective, single-center study conducted at an urban, academic emergency department (ED).

Systematic bias introduced by the informed consent process in a diagnostic research study.

Objectives: To determine population characteristics, outcomes, and reasons for unsuccessful enrollment among potential study subjects approached for written, informed consent in a minimal-risk emergency department (ED) study. The authors hypothesized that the prevalence of venous thromboembolism (VTE) would be lower among study participants and that medical acuity and refusal to provide a blood sample would be the most common reasons for nonparticipation.

Methods: The authors requested prospective, written, informed consent for a blood sample and follow-up from consecutive ED patients undergoing evaluation for pulmonary embolism (PE) and recorded spontaneously stated reasons for refusal.

Prospective study of the diagnostic accuracy of the simplify D-dimer assay for pulmonary embolism in emergency department patients.

Objective: To determine if a d-dimer assay (Simplify D-dimer; Agen Biomedical; Brisbane, Australia) can reliably exclude pulmonary embolism (PE) by producing a posttest probability of PE < 1% in low-risk, symptomatic emergency department (ED) patients.

Methods: Hemodynamically stable patients were evaluated for PE using a structured d-dimer-centered protocol; d-dimer testing was performed prior to imaging. Prior to testing, physicians completed an electronic data form that included their unstructured clinical estimate for the pretest probability of PE (< 15%, 15 to 40%, or > 40%) and the elements of the Charlotte rule and Canadian score for PE.

Multimarker panel to rule out acute coronary syndromes in low-risk patients.

Objectives: To test novel markers of acute coronary syndrome (ACS), monocyte chemoattractant protein-1 (MCP), myeloperoxidase (MPO), C-reactive protein (CRP), and brain natriuretic peptide (BNP) in low-risk emergency department (ED) patients who were evaluated for ACS in a chest pain unit (CPU).

Methods: A convenience sample of 414 patients underwent CPU evaluation, including provocative testing, and were followed prospectively for 45 days for ACS, which was defined as death, myocardial infarction (MI), revascularization, or >60% coronary artery stenosis prompting new medical treatment, adjudicated by three blinded reviewers. Published diagnostic thresholds were used to calculate diagnostic indices for each marker and for the multimarker panel.

Prospective multicenter study of quantitative pretest probability assessment to exclude acute coronary syndrome for patients evaluated in emergency department chest pain units.

Study Objective: We compare the diagnostic accuracy of 3 methods--attribute matching, physician's written unstructured estimate, and a logistic regression formula (Acute Coronary Insufficiency-Time Insensitive Predictive Instrument, ACI-TIPI)--of estimating a very low pretest probability (< or = 2%) for acute coronary syndromes in emergency department (ED) patients evaluated in chest pain units.

Methods: We prospectively studied 1,114 consecutive patients from 3 academic EDs, evaluated for acute coronary syndrome. Physicians collected data required for pretest probability assessment before protocol-driven chest pain unit testing.

Frequency of thrombophilia-related genetic variations in patients with idiopathic pulmonary embolism in an urban emergency department.

Background: The frequency of the thrombophilic genetic variants factor V Leiden (FVL) G1691A, prothrombin G20210A, and methylenetetrahydrofolate reductase (MTHFR) C677T in acutely symptomatic ambulatory patients with idiopathic pulmonary embolism (PE) has not been measured.

Methods: This prospective case-control study included patients presenting to urban emergency departments (EDs) with chest pain or shortness of breath. Cases were classified as idiopathic PE (49 patients with PE, but without overt risk factors for thrombosis).
