Emergency department overcrowding: the Emergency Department Cardiac Analogy Model (EDCAM)

Increasing patient numbers, changing demographics and altered patient expectations have all contributed to the current problem with 'overcrowding' in emergency departments (EDs). The problem has reached crisis level in a number of countries, with significant implications for patient safety, quality of care, staff 'burnout' and patient and staff satisfaction. There is no single, clear definition of the cause of overcrowding, nor a simple means of addressing the problem. For some hospitals, the option of ambulance diversion has become a necessity, as overcrowded waiting rooms and 'bed-block' force emergency staff to turn patients away. But what are the options when ambulance diversion is not possible? Christchurch Hospital, New Zealand is a tertiary level facility with an emergency department that sees on average 65,000 patients per year. There are no other EDs to whom patients can be diverted, and so despite admission rates from the ED of up to 48%, other options need to be examined. In order to develop a series of unified responses, which acknowledge the multifactorial nature of the problem, the Emergency Department Cardiac Analogy model of ED flow, was developed. This model highlights the need to intervene at each of three key points, in order to address the issue of overcrowding and its associated problems.     

A study of the workforce in emergency medicine: 2007

Introduction

This study was undertaken to describe the current status of the emergency medicine workforce in the United States.

Methods

Surveys were distributed in 2008 to 2619 emergency department (ED) medical directors and nurse managers in hospitals in the 2006 American Hospital Association database.

Results

Among ED medical directors, 713 responded, for a 27.2% response rate. Currently, 65% of practicing emergency physicians are board certified by the American Board of Emergency Medicine or the American Osteopathic Board of Emergency Medicine. Among those leaving the practice, the most common reasons cited for departure include geographic relocation (46%) and better pay (29%). Approximately 12% of the ED physician workforce is expected to retire in the next 5 years.Among nurse managers, 548 responded, for a 21% response rate. Many nurses (46%) have an associate degree as their highest level of education, 28% have a BSN, and 3% have a graduate degree (MSN or higher). Geographic relocation (44%) is the leading reason for changing employment.Emergency department annual volumes have increased by 49% since 1997, with a mean ED volume of 32 281 in 2007. The average reported ED length of stay is 158 minutes from registration to discharge and 208 minutes from registration to admission. Emergency department spent an average of 49 hours per month in ambulance diversion in 2007. Boarding is common practice, with an average of 318 hours of patient boarding per month.

Conclusions

In the past 10 years, the number of practicing emergency physicians has grown to more than 42 000. The number of board-certified emergency physicians has increased. The number of annual ED visits has risen significantly.     

Reducing Nonemergent Visits to the Emergency Department in a Veterans Affairs Multistate System

Study ObjectiveThe purpose of this quality improvement study was to reduce nonemergent visits to the emergency department attendance within a multistate Veterans Health Affairs network.MethodsTelephone triage protocols were developed and implemented for registered nurse staff to triage selected calls to a same-day telephonic or video virtual visit with a provider (physician or nurse practitioner). Calls, registered nurse triage dispositions, and provider visit dispositions were tracked for 3 months.ResultsThere were 1606 calls referred by registered nurses for provider visits. Of these, 192 were initially triaged as emergency department dispositions. Of these, 57.3% of calls that would have been referred to the emergency department were resolved via the virtual visit. Thirty-eight percent fewer calls were referred to the emergency department following licensed independent provider visit compared to the registered nurse triage.ConclusionTelephone triage services augmented by virtual provider visits may reduce emergency department disposition rates, resulting in fewer nonemergent patient presentations to the emergency department and reducing unnecessary emergency department overcrowding. Reducing nonemergent attendance to emergency departments can improve outcomes for patients with emergent dispositions.     

Emergency department overcrowding in the United States: an emerging threat to patient safety and public health

Numerous reports have questioned the ability of United States emergency departments to handle the increasing demand for emergency services. Emergency department (ED) overcrowding is widespread in US cities and has reportedly reached crisis proportions. The purpose of this review is to describe how ED overcrowding threatens patient safety and public health, and to explore the complex causes and potential solutions for the overcrowding crisis. A review of the literature from 1990 to 2002 identified by a search of the Medline database was performed. Additional sources were selected from the references of the articles identified. There were four key findings. (1) The ED is a vital component of America's health care "safety net". (2) Overcrowding in ED treatment areas threatens public health by compromising patient safety and jeopardising the reliability of the entire US emergency care system. (3) Although the causes of ED overcrowding are complex, the main cause is inadequate inpatient capacity for a patient population with an increasing severity of illness. (4) Potential solutions for ED overcrowding will require multidisciplinary system-wide support.     

Primary reasons for ED visits and procedures performed for patients who saw nurse practitioners.

INTRODUCTION: Little is known, from a national perspective, about what types of patients are seen by nurse practitioners in the emergency department. METHODS: Data from 1545 participating emergency departments across the United States during 1997, 1998, 1999, and 2000 were collected from nationally representative samples of urban and rural hospitals using the National Hospital Ambulatory Medical Care Surveys. Results Nurse practitioners saw 5.76 million ED patients during the 4-year period. Using the Reason for Visit Classification developed by the National Center for Health Statistics, the primary category for patients seen by nurse practitioners was classified as "Injury by type and/or location." The types of injuries in this category were lacerations and cuts to an upper extremity and facial area; injuries to the head, neck, and face; and foreign bodies in the eye. The next most common category was classified under "General symptoms." Nurse practitioners saw patients in this category with symptoms of chest pain, side or flank pain, fever, and edema. DISCUSSION: The findings from this study provide insight into the types of patient visits seen by nurse practitioners in emergency departments in the United States and the services and procedures that were received by patients.     

An Evaluation of a System-change Training Model to Improve Emergency Department Response to Battered Women

OBJECTIVES: To evaluate a system-change model of training from the Family Violence Prevention Fund and the Pennsylvania Coalition Against Domestic Violence for improving the effectiveness of emergency department (ED) response to intimate partner violence (IPV). METHODS: An experimental design with outcomes measured at baseline, 9-12, and 18-24 months post-intervention. Twelve hospitals in Pennsylvania and California with 20,000-40,000 annual ED visits were randomly selected and randomly assigned to experimental and control conditions. Emergency department teams (physician, nurse, social worker) from each experimental hospital and a local domestic violence advocate participated in a two-day didactic information and team planning intervention. RESULTS: The experimental hospitals were significantly higher than the control hospitals on a staff knowledge and attitude measure (F = 5.57, p = 0.019), on all components of the "culture of the ED" system-change indicator (F = 5.72, p = 0.04), and in patient satisfaction (F = 15.43, p < 0.001) after the intervention. There was no significant difference in the identification rates of battered women (F = 0.411, p = 0.52) (although the linear comparison was in the expected direction) in the medical records of the experimental and control hospitals. CONCLUSIONS: A system-change model of IPV ED training was effective in improving staff attitudes and knowledge about battered women and in protocols and staff training, as well as patient information and satisfaction. However, change in actual clinical practice was more difficult to achieve and may be influenced by institutional policy.     

Clinical review: Emergency department overcrowding and the potential impact on the critically ill

Critical care constitutes a significant and growing proportion of the practice of emergency medicine. Emergency department (ED) overcrowding in the USA represents an emerging threat to patient safety and could have a significant impact on the critically ill. This review describes the causes and effects of ED overcrowding; explores the potential impact that ED overcrowding has on care of the critically ill ED patient; and identifies possible solutions, focusing on ED based critical care.     

Barriers to implementing protocol-based sepsis resuscitation in the emergency department--results of a national survey

OBJECTIVE: To identify barriers to implementation of a written protocol for early goal-directed therapy for severe sepsis in the busiest emergency departments in the United States. DESIGN: Telephone survey with both quantitative and qualitative analysis. SETTING: Two busiest teaching and two busiest nonteaching emergency departments in each of the 25 most densely populated combined statistical areas in the United States. SUBJECTS: Twenty-four physician directors and 40 nursing managers representing 53% of the 100 emergency departments surveyed. INTERVENTIONS: Survey questionnaire. MEASUREMENTS AND MAIN RESULTS: Respondents identified lack of available nursing staff to perform the procedure, the inability to monitor central venous pressure in the emergency department, and challenges in identifying septic patients as the most frequent barriers. Although nurse managers and physicians identified similar barriers, nurses were more likely than physicians to list central venous catheter insertion as an important barrier (38% vs. 5%; p = .01), and physicians were more likely to endorse lack of agreement with the early goal-directed therapy resuscitation protocol (16% vs. 0%; p = .03). There were no statistically significant differences in the rankings assigned by clinicians from teaching and nonteaching hospitals. Qualitative analysis of open-ended questions identified barriers in a number of areas, including barriers to initiating the protocol process and factors that distinguish sepsis from other time-sensitive diseases in the emergency department. CONCLUSIONS: Nurse managers and physician directors of busy emergency departments representing the largest urban areas in the United States identify multiple barriers to implementing time-sensitive resuscitation to patients with severe sepsis. More than half of all respondents recognized a critical shortage of nursing staff, problems in obtaining central venous pressure monitoring, and challenges in identification of patients with sepsis as the largest roadblocks to overcome in implementing early goal-directed therapy.     

Reduced length of stay in medical emergency department patients: a prospective controlled study on emergency physician staffing.

OBJECTIVE: Patients, emergency department staff and hospital managers are often confronted with a prolonged length of stay of emergency department patients, with resulting overcrowding in the emergency department. We hypothesized that additional medical personnel would reduce the length of stay. METHODS: We prospectively studied consecutive patients managed in a medical emergency department by internal medicine residents during the evening shift. Data were collected on patients managed before (n=200) and after (n=160) the addition of a second physician on the shift. RESULTS: The addition of a physician in the busy evening shift decreased the length of stay from 176+/-137 to 141+/-86 min (mean+/-SD, P=0.012) for outpatients discharged after evaluation and management in the emergency department. The length of stay for emergency department inpatients admitted for hospitalization was not significantly reduced. CONCLUSION: An additional physician significantly reduced the length of stay of medical emergency department outpatients.     

A Survey of Workplace Violence Across 65 U.S. Emergency Departments

Objectives: Workplace violence is a concerning issue. Healthcare workers represent a significant portion of the victims, especially those who work in the emergency department (ED). The objective of this study was to examine ED workplace violence and staff perceptions of physical safety. Methods: Data were obtained from the National Emergency Department Safety Study (NEDSS), which surveyed staff across 69 U.S. EDs including physicians, residents, nurses, nurse practitioners, and physician assistants. The authors also conducted surveys of key informants (one from each site) including ED chairs, medical directors, nurse managers, and administrators. The main outcome measures included physical attacks against staff, frequency of guns or knives in the ED, and staff perceptions of physical safety. Results: A total of 5,695 staff surveys were distributed, and 3,518 surveys from 65 sites were included in the final analysis. One‐fourth of surveyed ED staff reported feeling safe sometimes, rarely, or never. Key informants at the sampled EDs reported a total of 3,461 physical attacks (median of 11 attacks per ED) over the 5‐year period. Key informants at 20% of EDs reported that guns or knives were brought to the ED on a daily or weekly basis. In multivariate analysis, nurses were less likely to feel safe “most of the time” or “always” when compared to other surveyed staff. Conclusions: This study showed that violence and weapons in the ED are common, and nurses were less likely to feel safe than other ED staff.     

If You Could Change 1 Thing to Improve the Quality of Emergency Care for Deliberate Self-harm Patients,What Would It Be? A National Survey of Nursing Leadership

IntroductionEmergency departments increasingly treat patients for deliberate self-harm. This study sought to understand emergency department nursing leadership perspectives on how to improve the quality of emergency care for these patients.MethodsED nursing managers and directors from a national sample of 476 hospitals responded to an open-ended question asking for the 1 thing they would change to improve the quality of care for self-harm patients who present in their emergency departments. We identified and coded key themes for improving the emergency management of these patients, then examined the distribution of these themes and differences by hospital characteristics, including urbanicity, patient volume, and teaching status.ResultsFive themes regarding how to improve care for deliberate self-harm patients were identified: greater access to hospital mental health staff or treatment (26.4%); better access to community-based services and resources (26.4%); more inpatient psychiatric beds readily accessible (20.9%); separate safe spaces in the emergency department (18.6%); and dedicated staff coverage (7.8%). Endorsement of findings did not differ based on hospital characteristics.DiscussionED nursing leadership strongly endorsed the need for greater access to both hospital- and community-based mental health treatment resources for deliberate self-harm patients. Additional ED staff and training, along with greater continuity among systems of care in the community, would further improve the quality of emergency care for these patients. Broad policies that address the scarcity of mental health services should also be considered to provide comprehensive care for this high-risk patient population.Key wordsEmergency department management of self-harm; Mental health care; Emergency nursing care     

Frequent Overcrowding in U.S. Emergency Departments

OBJECTIVE: To describe the definition, extent, and factors associated with overcrowding in emergency departments (EDs) in the United States as perceived by ED directors. METHODS: Surveys were mailed to a random sample of EDs in all 50 states. Questions included ED census, frequency, impact, and determination of overcrowding. Respondents were asked to rank perceived causes using a five-point Likert scale. RESULTS: Of 836 directors surveyed, 575 (69%) responded, and 525 (91%) reported overcrowding as a problem. Common definitions of overcrowding (>70%) included: patients in hallways, all ED beds occupied, full waiting rooms >6 hours/day, and acutely ill patients who wait >60 minutes to see a physician. Overcrowding situations were similar in academic EDs (94%) and private hospital EDs (91%). Emergency departments serving populations < or =250,000 had less severe overcrowding (87%) than EDs serving larger areas (96%). Overcrowding occurred most often several times per week (53%), but 39% of EDs reported daily overcrowding. On a 1-5 scale (+/-SD), causes of overcrowding included high patient acuity (4.3 +/- 0.9), hospital bed shortage (4.2 +/- 1.1), high ED patient volume (3.8 +/- 1.2), radiology and lab delays (3.3 +/- 1.2), and insufficient ED space (3.3 +/- 1.3). Thirty-three percent reported that a few patients had actual poor outcomes as a result of overcrowding. CONCLUSIONS: Episodic, but frequent, overcrowding is a significant problem in academic, county, and private hospital EDs in urban and rural settings. Its causes are complex and multifactorial.     

Patient satisfaction with triage nursing in a rural hospital emergency department

This study examined what relationships or differences exist between patient and nurse characteristics, satisfaction with triage nurse caring behaviors, general satisfaction with the triage nurse, and intent to return to a rural hospital emergency department (ED). The ED, located at a 401-bed teaching hospital in a small southern city, averages 28,000 visits annually. Samples of ED nurses (N = 11) and ED patients (N = 65) were asked to respond to demographic forms and the Consumer Emergency Care Satisfaction Scale (CECSS) Adapted. Findings indicated that the nurse's acuity rating and the patient's perception of condition had a positive relationship. The patient's perception of condition, patient satisfaction, and caring satisfaction were predictors of intent to return. When patients perceived themselves as seriously ill or injured, they expressed less intent to return to that ED.     

Cancer presentation in the emergency department: a failure of primary care.

Emergency departments are intended to be the location of entry into the health care system for patients with acute problems, such as injuries and myocardial infarctions. In contrast, cancer should optimally be detected during periodic health examinations, either through screening procedures or by early detection from signs and symptoms which prompt a routine visit to a primary care physician. This study was undertaken to describe patients who present to an emergency department with urgent symptoms and signs, are hospitalized, and subsequently diagnosed with cancer (ED group). One hundred twenty-nine patients were retrospectively studied. When compared with patients diagnosed in a primary care setting (tumor registry patients), the ED group was significantly older, more often male, had a significantly lower survival rate, and more frequent metastatic disease at diagnosis (P less than .001). The ED group accounted for 5.3% of the new tumor registry patients for the study years. Only 3.1% of the ED group had no insurance, and 21% reported no personal physician. Strategies are needed for patients and physicians to reduce the number of late-diagnosed cancer cases presenting in emergency departments.     

Managing rural emergency department overcrowding

Emergency department visits reached more than 115 million in 2005, a 30% increase over the past decade. Although much has been written regarding these numbers, little attention has been focused on the impact of overcrowding and volume increases on rural emergency departments. Rural emergency departments face challenges unlike their urban counterparts that make implementation of current overcrowding strategies difficult or impossible. This article addresses these challenges and suggests strategies specific to the needs of rural emergency departments.     

The Impact of Bed Traffic Control and Improved Flow Process on Throughput Measures in a Metropolitan Emergency Department

IntroductionED crowding is a complex phenomenon that presents many challenges to patients, hospitals, and staff. Using Lewin’s change model, we implemented an ED improvement plan, including an innovative bed traffic control and improved flow system. We hypothesized that this plan would reduce door-to-provider time and emergency medical service–offloading time, decrease the length of stay and number of patients leaving without being seen by a physician, and increase overall patient satisfaction.MethodsWe examined the ED improvement plan’s impact on institutional throughput metrics over a 4-year period (2015-2019). Data on door-to-provider time, door-to-discharge time, patient volume, leaving without being seen by a physician, and patient satisfaction by Press Ganey were analyzed.ResultsBetween 2015 and 2018, the median door-to-provider time decreased 56.9% and the median door-to-discharge time decreased 29.6%. Percentage of patients who left without being seen by a physician decreased 73.8%. In 2018, the patient satisfaction rank increased by 16 points (84.2% increase). Emergency medical services–offloading time decreased significantly, prompting a change of the 30-minute cutoff to 20 minutes. In 2018, 0.84% of patients had an offloading time of more than 20 minutes. Preliminary 2019 data show maintenance of this trend for all hospital metrics.DiscussionImplementing a pod system, with flow and bed placement managed by bed traffic control, reduced door-to-provider time, door-to-discharge time, leaving without being seen by a physician, emergency medical service–offload time, and increased patient satisfaction. Our results may provide a model for other emergency departments to effectively manage the challenges of crowding.     

Continuity of care in the transition from emergency department to general practitioner: Is it adequate?

Objective : To assess the adequacy of continuity of care for patients who are discharged to home or admitted to hospital from the emergency department. Methods : Questionnaire survey of emergency department communication practices. Results : Seventy-five of 86 emergency departments (87.2%) participated. Emergency departments failed to communicate with general practitioners upon disposition of many patients. For patients discharged to home, significantly more private emergency departments contacted general practitioners directly by telephone (P < 0.01) or by letter (P < 0.001). Significantly more public emergency departments gave patients a letter to take to their general practitioners (P < 0.01). Overall, emergency departments gave the patient a general practitioner letter some (33.3% of emergency department) or most (40.0%) of the time. Few letters were posted or faxed and little use of Email was made. Pre-formatted letters were used less than was expected. On patient admission, the telephone was used most frequently to advise general practitioners. Conclusions : Continuity of patient care may be inadequate in many emergency departments. Emergency departments should establish a check system to ensure that a communication is made with the general practitioners of all patients. Telephone or facsimile communication is recommended on patient admission. Other modes may be more appropriate on patient discharge to home. Structured, pre-formatted letters/facsimiles are recommended. Emergency department–general practitioner communications should be used as a performance indicator of emergency department practice.     

Access block causes emergency department overcrowding and ambulance diversion in Perth, Western Australia

Objective: Access block refers to the situation where patients in the emergency department (ED) requiring inpatient care are unable to gain access to appropriate hospital beds within a reasonable time frame. We systematically evaluated the relationship between access block, ED overcrowding, ambulance diversion, and ED activity.

Methods: This was a retrospective analysis of data from the Emergency Department Information System for the three major central metropolitan EDs in Perth, Western Australia, for the calendar years 2001–2. Bivariate analyses were performed in order to study the relationship between a range of emergency department workload variables, including access block (>8 hour total ED stay for admitted patients), ambulance diversion, ED overcrowding, and ED waiting times.

Results: We studied 259 580 ED attendances. Total diversion hours increased 74% from 3.39 hours/day in 2001 to 5.90 hours/day in 2002. ED overcrowding (r = 0.96; 95% confidence interval (CI) 0.91 to 0.98), ambulance diversion (r = 0.75; 95% CI 0.49 to 0.88), and ED waiting times for care (r = 0.83; 95% CI 0.65 to 0.93) were strongly correlated with high levels of ED occupancy by access blocked patients. Total attendances, admissions, discharges, and low acuity patient attendances were not associated with ambulance diversion.

Conclusion: Reducing access block should be the highest priority in allocating resources to reduce ED overcrowding. This would result in reduced overcrowding, reduced ambulance diversion, and improved ED waiting times. Improving hospital inpatient flow, which would directly reduce access block, is most likely to achieve this.
