Emergency Department Utilization in the United States and Ontario, Canada

Objectives: The current crisis in the emergency care system is characterized by worsening emergency department (ED) overcrowding. Lack of health insurance is widely perceived to be a major contributing factor to ED overcrowding in the United States. This study aimed to compare ED visit rates in the United States and Ontario, Canada, according to demographic and clinical characteristics.
Methods: This was a cross sectional study consisting of a nationally representative sample of 40,253 ED visits included in the 2003 National Hospital Ambulatory Medical Care Survey in the United States, and all ED visits recorded during 2003 by the National Ambulatory Care Reporting System in Ontario, Canada. The main outcome was the number of ED visits per 100 population per year.
Results: The annual ED visit rate in the United States was 39.9 visits (95% confidence interval = 37.2 to 42.6) per 100 population, virtually identical to the rate in Ontario, Canada (39.7 visits per 100 population). In both the United States and Ontario, Canada, those aged 75 years and older had the highest ED visit rate and women had a slightly higher ED visit rate than men. The most common discharge diagnosis was injury/poisoning, accounting for 25.6% of all ED visits in the United States and 24.7% in Ontario, Canada. Overall, 13.9% of ED patients in the United States were admitted to hospitals, compared with 10.5% in Ontario, Canada.
Conclusions: ED visit rates and patterns are similar in the United States and Ontario, Canada. Differences in health insurance coverage may not have a substantial impact on the overall utilization of emergency care.     

Atrial fibrillation in the elderly – Not a benign condition

Atrial fibrillation (AF) is the most commonly seen arrhythmia and its prevalence increases with age. In the general population, rates of 1–2% are reported but in older patients, the rates increase to over 10% (in those aged 85 years or older). Many older patients present to the emergency department (ED) with complaints that could be caused or associated with AF including valvular heart disease, hypertension, heart failure, an underlying infection (urinary or chest) and thyroid disorder. The most devastating complication of AF is stroke and early detection of AF and initiation of treatment (specifically the use of anti-coagulant medication) can significantly reduce the risk. AF is associated with high healthcare costs and has significant impacts on disability and quality of life especially if a stroke occurs.This review aims to describe the aetiology and treatment options for patients with newly diagnosed and previously diagnosed AF with an emphasis on how ED staff can manage older patients with AF and ensure optimal care is given. The treatment of AF has three main considerations (i) appropriateness for thromboembolic prophylaxis, (ii) rate control (including anti-arrhythmics, cardiac glycosides, B blockers and calcium channel blockers) and (iii) rhythm control with traditional cardioversion (either electrically or pharmacologically) or utilising interventional means to maintain sinus rhythm with cardiac surgery and more recently radio-frequency ablation. As anti-coagulation is widely implemented, the risks and benefits associated with warfarin and the newer agents will be described.Given that more than half of those with AF are over 75 years and 30% of AF is diagnosed incidentally, there is an imperative for prompt diagnosis to reduce the risk of debilitating complications especially stroke. AF should not be viewed as yet another concomitant “benign” condition. Emergency staff are well placed to detect AF and ensure appropriate treatment is commenced to reduce the adverse events associated with it.     

Practical use of dabigatran etexilate for stroke prevention in atrial fibrillation

Atrial fibrillation (AF) is associated with an increased risk of thromboembolism, and is the most prevalent factor for cardioembolic stroke. Vitamin K antagonists (VKAs) have been the standard of care for stroke prevention in patients with AF since the early 1990s. They are very effective for the prevention of cardioembolic stroke, but are limited by factors such as drug–drug interactions, food interactions, slow onset and offset of action, haemorrhage and need for routine anticoagulation monitoring to maintain a therapeutic international normalised ratio (INR). Multiple new oral anticoagulants have been developed as potential replacements for VKAs for stroke prevention in AF. Most are small synthetic molecules that target thrombin (e.g. dabigatran etexilate) or factor Xa (e.g. rivaroxaban, apixaban, edoxaban, betrixaban, YM150). These drugs have predictable pharmacokinetics that allow fixed dosing without routine laboratory monitoring. Dabigatran etexilate, the first of these new oral anticoagulants to be approved by the United States Food and Drug Administration and the European Medicines Agency for stroke prevention in patients with non‐valvular AF, represents an effective and safe alternative to VKAs. Under the auspices of the Regional Anticoagulation Working Group, a multidisciplinary group of experts in thrombosis and haemostasis from Central and Eastern Europe, an expert panel with expertise in AF convened to discuss practical, clinically important issues related to the long‐term use of dabigatran for stroke prevention in non‐valvular AF. The practical information reviewed in this article will help clinicians make appropriate use of this new therapeutic option in daily clinical practice.     

Refining the model for an emergency department-based mental health nurse practitioner outpatient service

Refining the model for an emergency department-based mental health nurse practitioner outpatient service
The mental health nurse practitioner (MHNP) role based in the emergency department (ED) has emerged in response to an increase in mental health-related presentations and subsequent concerns over waiting times, co-ordination of care and therapeutic intervention. The MHNP role also provides scope for the delivery of specialised primary care. Nursing authors are reporting on nurse-led outpatient clinics as a method of healthcare delivery that allows for enhanced access to health-care, particularly following hospital discharge. However, due to a lack of in-depth substantiation, this mode of service delivery requires more thorough investigation. This study describes the refinement phase undertaken before the implementation and pilot evaluation of a formalised and structured MHNP outpatient service in the ED of a large inner-city hospital in Sydney, Australia. An expert advisory panel (EAP) consisting of key local informants was convened to provide feedback on and refinement to the proposed model. This related to issues such as target population, structure and process considerations, outcome measures and interface within the overall health service. Findings from the EAP meeting are presented and discussed. The importance of linking methods with the appropriate methodology in evaluating a healthcare program is highlighted.     

Rabies postexposure prophylaxis: What the U.S. emergency medicine provider needs to know

Approximately 55,000 patients per year in the United States are exposed to potentially rabid animals and receive rabies postexposure prophylaxis (PEP) and these patients commonly present to the emergency department (ED) for wound care and PEP. Despite the number of rabies exposures seen in EDs each year, there appears to be a knowledge gap among health care providers with regard to prescribing and administering rabies PEP. The following review aims to bridge that knowledge gap by discussing the importance of obtaining a comprehensive exposure history to determine the category of the encounter, the type of animal, and the location of the bite and of consulting outside expert resources to determine whether the rabies PEP series is indicated. In addition, this article will discuss dosing, administration, and schedule of the rabies vaccine and human rabies immune globulin to ensure patients are fully protected from developing rabies. Lastly, this article discusses the potential cost associated with rabies PEP and provides information on managing this barrier.     

An Ethical Framework for the Management of Pain in the Emergency Department

Pain is a ubiquitous problem, affecting more than 100 million individuals in the United States chronically and many more in the acute setting. Up to three‐quarters of patients presenting to the emergency department (ED) report pain as a key component of their reasons for requiring acute care. While pain management is a fundamental component of emergency medicine (EM), there are numerous attitudinal and structural barriers that have been identified to effectively providing pain control in the ED. Coupled with public demands and administrative mandates, concerns surrounding ED pain management have reached a crisis level that should be considered an ethical issue in the profession of EM. In this article, the authors propose an ethical framework based on a combination of virtue, narrative, and relationship theories that can be used to address the clinical dilemmas that arise in managing pain in ED patients.     

Can I Send This Patient with Stroke Home? Strategies Managing Transient Ischemic Attack and Minor Stroke in the Emergency Department

Background

While transient ischemic attack and minor stroke (TIAMS) are common conditions evaluated in the emergency department (ED), there is controversy regarding the most effective and efficient strategies for managing them in the ED. Some patients are discharged after evaluation in the ED and cared for in the outpatient setting, while others remain in an observation unit without being admitted or discharged, and others experience prolonged and potentially costly inpatient admissions.

Coronavirus Disease 2019 in the Emergency Department: Establishing an Interprofessional Incident Command System

Coronavirus disease 2019 was declared a national emergency in the United States on March 13, 2020, at which time the Children’s National Hospital Emergency Department in Washington, DC, mobilized to develop and implement a unit-based Incident Command System. Anticipating that the unique and challenging nature of this pandemic might require a large interprofessional team, emergency nurses, emergency physicians, and emergency physician assistants were placed in traditional Incident Command System roles to provide an organizational framework for the ED response. This framework served multiple purposes but most importantly it helped to efficiently streamline and coordinate communications within the emergency department, with hospital leadership and with other hospital departments. The focus on intentionally taking an interprofessional approach to assigning Incident Command System roles was key to optimize staff safety, patient care, and clinical efficiency. This paper highlights a unique concept of applying the Incident Command System model to a single hospital department in a disaster scenario, using existing ED staff to function in various roles not typically held during regular operations. Given that policies and procedures can be ever-changing during a pandemic, emergency departments can implement an interprofessional incident command structure to provide a framework for communications and operational planning that allows for agility based on evolving priorities. The Children’s National Hospital ED Incident Command System model established during the coronavirus disease 2019 pandemic can serve as a guide for other emergency departments during a disaster response.     

International perspectives on emergency department crowding

The maturation of emergency medicine (EM) as a specialty has coincided with dramatic increases in emergency department (ED) visit rates, both in the United States and around the world. ED crowding has become a public health problem where periodic supply and demand mismatches in ED and hospital resources cause long waiting times and delays in critical treatments. ED crowding has been associated with several negative clinical outcomes, including higher complication rates and mortality. This article describes emergency care systems and the extent of crowding across 15 countries outside of the United States: Australia, Canada, Denmark, Finland, France, Germany, Hong Kong, India, Iran, Italy, The Netherlands, Saudi Arabia, Catalonia (Spain), Sweden, and the United Kingdom. The authors are local emergency care leaders with knowledge of emergency care in their particular countries. Where available, data are provided about visit patterns in each country; however, for many of these countries, no national data are available on ED visits rates or crowding. For most of the countries included, there is both objective evidence of increases in ED visit rates and ED crowding and also subjective assessments of trends toward higher crowding in the ED. ED crowding appears to be worsening in many countries despite the presence of universal health coverage. Scandinavian countries with robust systems to manage acute care outside the ED do not report crowding is a major problem. The main cause for crowding identified by many authors is the boarding of admitted patients, similar to the United States. Many hospitals in these countries have implemented operational interventions to mitigate crowding in the ED, and some countries have imposed strict limits on ED length of stay (LOS), while others have no clear plan to mitigate crowding. An understanding of the causes and potential solutions implemented in these countries can provide a lens into how to mitigate ED crowding in the United States through health policy interventions and hospital operational changes.     

Practical implications of implementing emergency department crowding interventions: summary of a moderated panel

Emergency department (ED) crowding continues to be a major public health problem in the United States and around the world. In June 2011, the Academic Emergency Medicine consensus conference focused on exploring interventions to alleviate ED crowding and to generate a series of research agendas on the topic. As part of the conference, a panel of leaders in the emergency care community shared their perspectives on emergency care, crowding, and some of the fundamental issues facing emergency care today. The panel participants included Drs. Bruce Siegel, Sandra Schneider, Peter Viccellio, and Randy Pilgrim. The panel was moderated by Dr. Jesse Pines. Dr. Siegel's comments focused on his work on Urgent Matters, which conducted two multihospital collaboratives related to improving ED crowding and disseminating results. Dr. Schneider focused on the future of ED crowding measures, the importance of improving our understanding of ED boarding and its implications, and the need for the specialty of emergency medicine (EM) to move beyond the discussion of unnecessary visits. Dr. Viccellio's comments focused on several areas, including the need for a clear message about unnecessary ED visits by the emergency care community and potential solutions to improve ED crowding. Finally, Dr. Pilgrim focused on the effect of effective leadership and management in crowding interventions and provided several examples of how these considerations directly affected the success or failure of well-constructed ED crowding interventions. This article describes each panelist's comments in detail.     

Development of Geriatric Competencies for Emergency Medicine Residents Using an Expert Consensus Process

Background: The emergency department (ED) visit rate for older patients exceeds that of all age groups other than infants. The aging population will increase elder ED patient utilization to 35% to 60% of all visits. Older patients can have complex clinical presentations and be resource‐intensive. Evidence indicates that emergency physicians fail to provide consistent high‐quality care for elder ED patients, resulting in poor clinical outcomes. Objectives: The objective was to develop a consensus document, “Geriatric Competencies for Emergency Medicine Residents,” by identified experts. This is a minimum set of behaviorally based performance standards that all residents should be able to demonstrate by completion of their residency training. Methods: This consensus‐based process utilized an inductive, qualitative, multiphase method to determine the minimum geriatric competencies needed by emergency medicine (EM) residents. Assessments of face validity and reliability were used throughout the project. Results: In Phase I, participants (n = 363) identified 12 domains and 300 potential competencies. In Phase II, an expert panel (n = 24) clustered the Phase I responses, resulting in eight domains and 72 competencies. In Phase III, the expert panel reduced the competencies to 26. In Phase IV, analysis of face validity and reliability yielded a 100% consensus for eight domains and 26 competencies. The domains identified were atypical presentation of disease; trauma, including falls; cognitive and behavioral disorders; emergent intervention modifications; medication management; transitions of care; pain management and palliative care; and effect of comorbid conditions. Conclusions: The Geriatric Competencies for EM Residents is a consensus document that can form the basis for EM residency curricula and assessment to meet the demands of our aging population.

Implementation of an integrated emergency department acute atrial fibrillation pathway safely reduces cardioversions and hospitalisations: A comparative pre–post study

Objective

Atrial fibrillation/flutter (AF/AFL) accounts for high rates of ED presentations and hospital admissions. There is increasing evidence to suggest that delaying cardioversion for acute uncomplicated AF is safe, and that many patients will spontaneously revert to sinus rhythm (SR). We conducted a before-and-after evaluation of AF/AFL management after a change in ED pathway using a conservative ‘rate-and-wait’ approach, incorporating next working day outpatient clinic follow-up and delayed cardioversion if required.

Methods

We performed a before-and-after retrospective cohort study examining outcomes for patients who presented to the ED in Christchurch, New Zealand, with acute uncomplicated AF/AFL in the 1-year period before and after the implementation of a new conservative management pathway.

Results

A total of 360 patients were included in the study (182 ‘Pre-pathway’ vs 178 ‘Post-Pathway’). Compared to the pre-pathway cohort, those managed under the new pathway had an 81.2% reduction in ED cardioversions (n = 32 vs n = 6), and 50.7% reduction in all cardioversions (n = 65 vs n = 32). There was a 31.6% reduction in admissions from ED (n = 54 vs n = 79). ED length of stay (3.9 h vs 3.8 h, net difference −0.1 h, 95% confidence interval [CI] −0.6 to 0.3), 1-year ED AF representation (32.4% vs 26.4%, net difference −6.0% [95% CI −16.0% to 3.9%]), 1-year ED ischaemic stroke presentation (2.2% in both groups) and 7-day all-cause mortality rates (hazard ratio 1.05 [95% CI 0.6 to 1.9]) were all similar.

Conclusions

Using a conservative ‘rate-and-wait’ strategy with early follow-up for patients presenting to ED with AF/AFL can safely reduce unnecessary cardioversions and avoidable hospitalisations.     

New oral anticoagulants in the ED setting: a review

Background

Emergency department (ED) clinicians are not typically involved in the long-term management of patients' anticoagulation therapy, but they are responsible for decision making for emergency conditions requiring anticoagulation, such as acute venous thromboembolism (VTE). In addition, emergency physicians are often faced with patients who present first to the ED with conditions that may prompt long-term anticoagulation upon hospital discharge, such as atrial fibrillation (AF), or who have acute or potential bleeding complications from anticoagulation.

Objective

In this review, clinical trials of new oral anticoagulants evaluated for treatment of VTE and stroke prophylaxis in AF, as well as practical management aspects, will be discussed. In addition, clinical trials evaluating the adjunctive use of the new oral anticoagulants with antiplatelet therapy in patients who have experienced acute coronary syndrome will be explored.

Discussion

Both dabigatran etexilate and rivaroxaban have successfully completed phase III trials for acute VTE treatment and are currently approved for the reduction of risk of stroke and systemic embolism in patients with nonvalvular AF. In a recently completed phase III trial, apixaban also demonstrated promising efficacy and safety in that indication. Rivaroxaban represents the only new anticoagulant to date to have shown promising phase III results as an adjunct to antiplatelet therapy after acute coronary syndrome.

Conclusion

Knowledge of the appropriate clinical use and safety concerns of the new anticoagulants is imperative as they become more frequently prescribed, and their potential uses in the ED setting represent an important aspect of continuing education for emergency physicians.     

Antithrombotic therapy for prevention of stroke in clinical practice in the ED

OBJECTIVE: The objective of this study was to analyze the emergency medicine department's practice of recommending anticoagulation medication for stroke prevention, its compliance with clinical guidelines, and the role of the emergency physician in recommending anticoagulation medication. We also determined the occurrence of thromboembolic events in patients with atrial fibrillation (AF) during a follow-up period of up to 8 months after their discharge from the ED. MATERIALS AND METHODS: Over a 6-month period, patients presenting to the ED with AF were registered using a predesigned 2-part questionnaire. The first part considered the management of the patients with AF at the ED; the second part evaluated data on patients who returned to the ED and their treatment follow-up, based on the drug supply registry. RESULTS: This study included 102 ED visits by patients with AF, of whom 38 were hospitalized and 64 were discharged. Thirty-six of the discharged patients required anticoagulation according to American College of Cardiology/American Heart Association Task Force on Practice Guidelines/European Society of Cardiology guidelines. Of these patients, 28 (78%) were recommended anticoagulation medication and 8 (25%) were not: 5 because of contraindications and 3 because of unknown reasons. No patient returned to the ED with a thromboembolic event during the 8-month follow-up period. CONCLUSION: The prevalence of anticoagulation recommendation for stroke prevention and compliance with clinical guidelines were found to be greater than previously reported. Our data show that most of the patients with AF and risk factors for stroke were recommended anticoagulation medication. This study illustrates the importance of applying clinical guidelines in daily practice and integrating them into patients' medical files in the ED.     

Acute ischemic stroke

Primary care providers play an instrumental role in both coordinating prevention efforts and facilitating emergency care for patients with signs and symptoms of acute ischemic stroke. Acute Ischemic stroke, also known as brain attack, is the third leading cause of death and the leading cause of adult disability in the United States. Acute ischemic stroke is currently considered a medical emergency that can respond to early treatment. In addition, primary and secondary prevention activities have proved effective. This article reviews the current literature regarding the types of stroke as well as specific information about prevention, signs and symptoms, and management. Guidelines for assessment and emergency care for patients with acute ischemic stroke are also provided.     

Trends in outpatient emergency department visits during the COVID-19 pandemic at a large,urban, academic hospital system

BackgroundThe coronavirus disease 2019 (COVID-19) pandemic has critically affected healthcare delivery in the United States. Little is known on its impact on the utilization of emergency department (ED) services, particularly for conditions that might be medically urgent. The objective of this study was to explore trends in the number of outpatient (treat and release) ED visits during the COVID-19 pandemic.MethodsWe conducted a cross-sectional, retrospective study of outpatient emergency department visits from January 1, 2019 to August 31, 2020 using data from a large, urban, academic hospital system in Utah. Using weekly counts and trend analyses, we explored changes in overall ED visits, by patients' area of residence, by medical urgency, and by specific medical conditions.ResultsWhile outpatient ED visits were higher (+6.0%) in the first trimester of 2020 relative to the same period in 2019, the overall volume between January and August of 2020 was lower (−8.1%) than in 2019. The largest decrease occurred in April 2020 (−30.4%), followed by the May to August period (−12.8%). The largest declines were observed for visits by out-of-state residents, visits classified as non-emergent, primary care treatable or preventable, and for patients diagnosed with hypertension, diabetes, headaches and migraines, mood and personality disorders, fluid and electrolyte disorders, and abdominal pain. Outpatient ED visits for emergent conditions, such as palpitations and tachycardia, open wounds, syncope and collapse remained relatively unchanged, while lower respiratory disease-related visits were 67.5% higher in 2020 relative to 2019, particularly from March to April 2020. However, almost all types of outpatient ED visits bounced back after May 2020.ConclusionsOverall outpatient ED visits declined from mid-March to August 2020, particularly for non-medically urgent conditions which can be treated in other more appropriate care settings. Our findings also have implications for insurers, policymakers, and other stakeholders seeking to assist patients in choosing more appropriate setting for their care during and after the pandemic.     

Mosher and Jernigan's 'Making the link: a public health approach to preventing alcohol-related violence and crime'

While alcohol problems are over-represented in primary care settings and in emergency departments (EDs), screening for alcohol use disorders has not been a routine part of care in the United States, and little is known of the performance of screening instruments for problem drinking, particularly among women and ethnic minorities. The sensitivity and specificity of the CAGE, BMAST, AUDIT, TWEAK, and RAPS are compared against DSM-IV and ICD-10 criteria for alcohol dependence in probability samples of black patients interviewed in the ED (n= 1091) and primary care clinics (n = 711) in Jackson, Mississippi. Instruments appeared to perform better in the ED than in primary care. The CAGE and RAPS appeared to perform best in the primary care sample, and the AUDIT and RAPS in the ED sample. While the prevalence of alcohol dependence in the primary care clinics was lower than in the ED, findings suggest that both sites are important for screening and identification of patients with alcohol use disorders. Further research is needed for determining those screening instruments which perform optimally in identifying problem drinking patients across clinical sites.     

Implementation of an Emergency Department–based Transient Ischemic Attack Clinical Pathway: A Pilot Study in Knowledge Translation

Objectives To assess the feasibility of implementing an emergency department (ED)—based transient ischemic attack (TIA) clinical pathway that uses computer-based clinical support, and to evaluate measures of quality, safety, and efficiency.
Methods This was a prospective cohort study of adult patients presenting to a community ED with symptoms consistent with acute TIA. Adherence to the clinical pathway served as a test of feasibility. Compliance with guideline recommendations for antithrombotic therapy and vascular imaging were used as process measures of quality. The 90-day risk of recurrent TIA, stroke, or death provided estimates of safety. Efficiency was assessed by measuring the rate of uneventful hospitalization, defined as a hospital admission that did not result in any major medical event or vascular intervention such as endarterectomy or stent placement.
Results Of the 75 subjects enrolled, physician adherence to the clinical pathway was 85.3%, and 35 patients (46.7%) were discharged home from the ED. Antithrombotic agents were prescribed to 68 (90.7%), and vascular imaging was performed in 70 (93.3%). The 90-day risk of recurrent TIA was seven out of 75 (9.3%; 95% confidence interval [CI] = 4.6% to 18.0%), one patient experienced stroke (1.3%; 95% CI = 0.2% to 7.2%), and three patients died (4.0%; 95% CI = 1.4% to 11.1%). Uneventful hospitalization occurred in 38 of 40 patients (95.0%).
Conclusions Implementation of a clinical pathway for the evaluation and management of TIA using computer-based clinical support is feasible in a community ED setting. This pilot study in knowledge translation provides a design framework for further studies to assess the safety and efficiency of a structured ED-based TIA clinical pathway.
