The Impact of Two Freestanding Emergency Departments on a Tertiary Care Center

Background

Freestanding emergency departments (FEDs) have become increasingly popular as the need for emergency care continues to grow.

Objective

To analyze the impact of two FEDs on a local tertiary care center’s patient volume and admission rates.

Methods

A retrospective analysis examined monthly volume and admission rates for the main ED and two FEDs located 9.6 and 12 miles away. Main ED census records were divided into three distinct time frames: period A (control) was January 2007 through June 2007. Period B was July 2007 through July 2009 when one FED was open. Period C was August 2009 through June 2010 when both FEDs were open. A two-factor analysis of variance was used to analyze admission rates while adjusting for monthly variation.

Results

The mean monthly patient volume for the main ED was 4709 for period A, but dropped significantly (p < 0.01) to 4447 for period B, and again dropped significantly (p < 0.01) to 4242 during period C. The volume for all facilities increased throughout the study period. A combined monthly volume increase to 5642 occurred in Period B, and increased to 6808 in Period C. The adjusted mean admission rate at the main ED for period A was 0.221, which dropped somewhat, though not significantly (p = 0.3505) to 0.213 for period B, and then significantly (p < 0.01) to 0.189 for period C.

Conclusion

Opening two FEDs decreased the volume and admission rates for the main ED and increased the overall ED volume for the health care system.     

Most Transfers from Urgent Care Centers to Emergency Departments Are Discharged and Many Are Unnecessary

Background

Urgent care centers (UCCs) can offer a cheap alternative to emergency departments (EDs) for some patients with acute complaints. However, if patients who initially present to a UCC are unnecessarily transferred to an ED, those patients may suffer undue financial harm. The group of patients transferred from UCCs to EDs have never previously been studied.

Door-to-Balloon Times from Freestanding Emergency Departments Meet ST-Segment Elevation Myocardial Infarction Reperfusion Guidelines

Background

Freestanding emergency departments (FEDs) introduce a challenge to physicians who care for the patient with an ST-segment elevation myocardial infarction (STEMI) because treatment is highly time dependent. FEDs have no percutaneous coronary intervention (PCI) capabilities, which necessitates transfer to a PCI-capable facility or fibrinolysis.

Study Objective

Our aim was to determine the proportion of STEMI patients who arrived to an FED and were subsequently transferred for PCI and met the door-to-balloon reperfusion guidelines of 90 min.

Methods

This was a dual-center retrospective cohort review of all patients 18 years and older who were diagnosed with an STEMI and presented to the main hospital−affiliated FEDs. Electronic medical records and emergency medical services documentation were reviewed for all cases since the opening of the FEDs in July 2007 and August 2009, respectively. Key time points were abstracted and statistical evaluation was performed using Fisher's exact test.

Results

A total of 47 patients met inclusion criteria. Median door-to-transport time was 34 min (interquartile range [IQR] 15 min). Median transport time from the FEDs to the main hospital catheterization laboratory was 21 min (IQR 5 min). Median arrival at the catheterization laboratory-to-balloon time was 25 min (IQR 13 min). Median total door-to-balloon time was 83 min (IQR 10.5 min), with 78.7% meeting the American Heart Association's recommended guidelines of ≤ 90 min.

Conclusion

STEMI patients initially seen at two FEDs achieved door-to-balloon time goals of < 90 min.     

Information Technology in Emergency Medicine Residency–Affiliated Emergency Departments

OBJECTIVES: To describe acquisition and implementation of information technology (IT) in U.S. emergency medicine (EM) residency-affiliated emergency departments (EDs), including automatic medication error checking. METHODS: This was a survey of all U.S. EM residencies active in September 2000. Respondents specified whether specific IT tools had been "acquired" and "implemented fully." EDs were categorized according to primary versus affiliated training site, trauma level, and census. Numbers of "yes" responses were compared according to ED type (Kruskal-Wallis test, p < or = 0.05 significant). RESULTS: Of 121 residency programs, data were obtained from 93 (77%) for a total of 149 EDs. The percentages of EDs that reported full implementation for each technology are as follows: medication error checking, 7%; medication order entry, 18%; nonmedication orders, 7%; clinical documentation, 21%; old electrocardiograms, 62%; laboratory results, 84%; radiography order entry, 62%; image retrieval, 29%; radiologists' interpretations, 67%; cardiology reports, 62%; pathology reports, 70%; surgical reports/dictations, 60%; triage, 34%; tracking, 46%; electronic reference materials, 56%; registration, 84%; accounts, 72%; patient management software package, 20%; voice recognition, 7%. Trauma centers reported more IT tools than nontrauma centers (p = 0.01), and primary training sites reported fewer IT tools than affiliated EDs (p = 0.027). CONCLUSIONS: Incorporation of IT is not uniform in EDs where EM residents train. Acquisition of effective IT tools varies, and implementation lags behind acquisition. Fully implemented IT for medication error checking was reported in 7% of EDs; an additional 12% had acquired IT without implementing it fully.     

Academic Departments of Emergency Medicine: The Effects of Managed Care

Abstract. Objective: To survey academic departments of emergency medicine (ADEMs) concerning the effects of managed care on their operation and practice. Methods: A 38-question survey was mailed to the chairs of all 52 ADEMs in the United States requesting information concerning managed care activity and its effects on ADEMs in academic years 1994–1995 and 1995–1996. Results: Forty-seven ADEMs (90.3%) responded. When comparing the 1995–1996 and 1994–1995 academic years, the following changes were noted: decreased overall growth in ED patient volume (38.3% vs 51.1%), larger percentage of respondents reporting an actual decrease in ED patient volume (38% vs 27.6%), less growth in ED gross revenue (43.7% vs 52.1%), larger percentage of ADEMs reporting actual decreased gross revenues (25% vs 12.5%), increase in ED patient acuity (76.6% vs 59.6%), and relative stability in the number of EM faculty (40.4% vs 44.7% reporting no change in faculty number). Two-thirds of ADEMs used mid-level providers (i.e., physician assistants, nurse practitioners), most commonly in a fast-track setting (41%). Thirty percent of ADEMs reported that other academic departments actively directed patients away from the ED, with pediatrics, family medicine, and internal medicine the most active. Ninety-eight percent of ADEMs reported ongoing negotiations between their institution or hospital and managed care organizations (MCOs); only 54.3% of ADEMs were involved in these negotiations. Twenty-eight percent of ADEMs reported MCOs have had an effect on their emergency medical services system, with 37% indicating HMOs routinely discouraged their enrollees from using 9-1-1 services and 16% reporting HMOs provided 9-1-1 services to take patients only to participating hospital EDs. Conclusion: ADEMs have experienced significant changes in nearly every aspect of their practice over the two academic years under study, much of which is due to managed care. ADEMs must take a leadership role in dealing with MCOs.     

A Comparison of HIV Testing in the Emergency Department and Urgent Care

Background: Although national guidelines recommend universal human immunodeficiency virus (HIV) testing, emergency departments (EDs) may choose to limit testing to certain patients, such as those triaged to urgent care (UC). Objective: To compare the results of rapid HIV testing in an urban ED with an affiliated UC. Methods: This was a retrospective analysis of an HIV testing program that included screening, which was initiated by triage nurses, and diagnostic testing, which was initiated by clinicians. Eligible patients were ≥ 12 years old and medically stable. Results: From April 2005 through December 2006, HIV tests were completed in 6196 (8.3%) of the 74,331 ED visits and 3256 (8.8%) of the 37,169 UC visits. Screening accounted for 5009 (80.8%) of the ED tests and 2914 (89.5%) of the UC tests, and diagnostic testing accounted for the remainder. Eighty (1.3%) of the ED tests and 21 (0.6%) of the UC tests were positive (p = 0.0024). Compared with newly diagnosed HIV-positive ED patients, HIV-positive UC patients were less likely to have CD4 counts < 200 cells/μL (adjusted odds ratio 0.19, 95% confidence interval 0.05–0.65). Conclusion: Although the yield of HIV testing is greater among ED patients, UC patients are diagnosed at a less advanced stage of illness.     

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.     

Use of Emergency Departments by Elder Patients: A Five -year Follow-up Study

Abstract. Objective: Tb compare the use of emergency medical care by elders in the United States in 1995 with that previously described for 1990. Methods: A computerized billing database of 88 EDs in 21 states was retrospectively reviewed for 1995, comparing elder and nonelder patients, estimating national use of emergency medical services by elders, and comparing the 1995 data with previously published results for 1990. Results: From 1990 to 1995, the number of ED visits in the United States increased from 92 million to 100 million. The number of visits made by patients aged 65 years or older increased from 13,639,400 (15%) to 15,666,300 (15.7%), but this increase did not reach statistical significance (p = 0.17). The admission rate for elder ED patients increased from 32% to 46% over the five-year interval (p < 0.01). This represents more than 7 million hospital admissions for elder patients in 1995. The rate of intensive care unit (ICU) admission for elders decreased from 7% to 6% over the five-year interval (p = 0.56), compared with 1.3% for nonelder patients for both years. Thirty percent of elder ED patients arrived by ambulance in 1990, compared with 33% in 1995 (p = 0.02). Based on 1995 data, elders comprised 39% of patients arriving by ambulance [odds ratio (OR) 4.75, 95% confidence interval (CI) = 4.71 to 4.79], 43% of all admissions (OR 6.59, 95% CI = 6.54 to 6.64), and 47% of ICU admissions (OR 5.00, 95% CI = 4.91 to 5.09). The comparable ORs in 1990 were 4.4, 5.6, and 5.5, respectively. Conclusions: From 1990 to 1995, the overall number of ED visits increased. The rate of increase was somewhat greater for elder patients. The use of ambulance services also disproportionately grew among elder patients, as did the rate of hospital admission. The overall rate of ICU admission was stable, but actually fell modestly for elder patients. Of these changes, only the increase in the rate of hospital admission for elders reached statistical significance.     

Literature-based Recommendations for Suicide Assessment in the Emergency Department: A Review

Background

Suicidal ideation and attempted suicide are important presenting complaints in the Emergency Department (ED). The Joint Commission established a National Patient Safety Goal that requires screening for suicidal ideation to identify patients at risk for suicide.

Objectives

Given the emphasis on screening for suicidal ideation in the general hospital and ED, it is important for Emergency Physicians to be able to understand and perform suicide risk assessment.

Methods

A review of literature was conducted using PubMed to determine important elements of suicide assessment in adults, ages 18 years and over, in the ED. Four typical ED cases are presented and the assessment of suicide risk in each case is discussed.

Results

The goal of an ED evaluation is to appropriately determine which patients are at lowest suicide risk, and which patients are at higher or indeterminate risk such that psychiatry consultation is warranted while the patient is in the ED. Emergency clinicians should estimate this risk by taking into account baseline risk factors, such as previous suicide attempts, as well as acute risk factors, such as the presence of a suicide plan.

Conclusion

Although a brief screening of suicide risk in the ED does not have the sensitivity to accurately determine which patients are at highest risk of suicide after leaving the ED, patients at lowest risk may be identified. In these low-risk patients, psychiatric holds and real-time psychiatric consultation while in the ED may not be needed, facilitating more expeditious dispositions from the ED.     

Emergency Medical Services Fellowship in the United States of America

Travelling outside Australia to undertake further training in an area of subspecialty interest is both interesting and beneficial to the advancement of the individual and our specialty. In the United States of America, such formal training following completion of specialist qualification in emergency medicine is referred to as ‘Fellowship’ training. While other authors have discussed the general areas of overseas work and emergency medicine Fellowships, this paper specifically addresses the area of prehospital care, known in the United States as ‘emergency medical services’. Although there are significant differences in prehospital care between the United States and Australia, a great deal of what can be learned from undertaking a Fellowship in prehospital care in the United States is locally applicable. A typical curriculum is outlined, and the steps in selecting and arranging such a programme are discussed. Some potential pitfalls are also mentioned. Given the paucity of formal training in prehospital care in this country, such fellowship programmes are an excellent means of obtaining a very solid understanding of this important aspect of emergency medicine.     

Filming of Patients in Academic Emergency Departments

With increasing availability and utilization of advanced technologic modalities in medicine, questions frequently arise regarding the appropriate use of recorded images of patients. While recorded images (photography, video, etc.) of patients may often be appropriate for documentation, medical record use, peer review, and teaching, the nonmedical use of recorded images for entertainment or commercial purposes is more problematic, both ethically and procedurally. Practices regarding filming of patients in academic emergency departments are reviewed, and suggested guidelines are provided regarding the appropriate and inappropriate filming of patients.     

Dizziness Presentations in U.S. Emergency Departments, 1995–2004

Objectives:  The objectives were to describe presentation characteristics and health care utilization information pertaining to dizziness presentations in U.S. emergency departments (EDs) from 1995 through 2004.
Methods:  From the National Hospital Ambulatory Medical Care Survey (NHAMCS), patient visits to EDs for "vertigo-dizziness" were identified. Sample data were weighted to produce nationally representative estimates. Patient characteristics, diagnoses, and health care utilization information were obtained. Trends over time were assessed using weighted least squares regression analysis. Multivariable logistic regression analysis was used to control for the influence of age on the probability of a vertigo-dizziness visit during the study time period.
Results:  Vertigo-dizziness presentations accounted for 2.5% (95% confidence interval [CI] = 2.4% to 2.6%) of all ED presentations during this 10-year period. From 1995 to 2004, the rate of visits for vertigo-dizziness increased by 37% and demonstrated a significant linear trend (p < 0.001). Even after adjusting for age (and other covariates), every increase in year was associated with increased odds of a vertigo-dizziness visit. At each visit, a median of 3.6 diagnostic or screening tests (95% CI = 3.2 to 4.1) were performed. Utilization of many tests increased over time (p < 0.01). The utilization of computerized tomography and magnetic resonance imaging (CT/MRI) increased 169% from 1995 to 2004, which was more than any other test. The rate of central nervous system diagnoses (e.g., cerebrovascular disease or brain tumor) did not increase over time.
Conclusions:  In terms of number of visits and important utilization measures, the impact of dizziness presentations on EDs is substantial and increasing. CT/MRI utilization rates have increased more than any other test.     

Pediatric Tree House–Related Injuries Treated in Emergency Departments in the United States: 1990–2006

Objectives:  The objective was to describe the epidemiology of tree house–related injuries in the United States among children and adolescents.
Methods:  The authors conducted a retrospective analysis using data from the National Electronic Injury Surveillance System for patients ≤19 years who were treated in an emergency department (ED) for a tree house–related injury from 1990 through 2006.
Results:  An estimated 47,351 patients ≤19 years of age were treated in EDs for tree house–related injuries over the 17-year study period. Fractures were the most common diagnosis (36.6%), and the upper extremities were the most commonly injured body part (38.8%). The odds of sustaining a head injury were increased for children aged <5 years. Falls were the most common injury mechanism (78.6%) and increased the odds of sustaining a fracture. Falls or jumps from a height ≥10 feet occurred in 29.3% of cases for which height of the fall/jump was recorded. Boys had significantly higher odds of falling or jumping from a height of ≥10 ft than girls, and children 10 to 19 years old also had significantly higher odds of falling or jumping from a height of ≥10 feet, compared to those 9 years old and younger. The odds of hospitalization were tripled if the patient fell or jumped from ≥10 feet and nearly tripled if the patient sustained a fracture.
Conclusions:  This study examined tree house–related injuries on a national level. Tree house safety deserves special attention because of the potential for serious injury or death due to falls from great heights, as well as the absence of national or regional safety standards. The authors provide safety and prevention recommendations based on the successful standards developed for playground equipment.
