International perspectives on emergency department crowding

Emergency department visit volume variability

OBJECTIVE

One of the most important and basic variables in emergency department (ED) operations is patient visit volumes. This variable is usually predicted on the basis of the average ED patient visit volume over a certain period. However, ED patient visit variability is poorly understood. Therefore, we evaluated ED patient visit variability in order to determine if the average can be used to operate EDs.

METHODS

Nationwide ED patient visit data were from the standard emergency patient data of the National Emergency Department Information System. The data are transferred automatically by 141 EDs nationwide. The hourly ED visit volumes over 365 days were determined, and the variability was analyzed to evaluate the representativeness of the average.

RESULTS

A total of 4,672,275 patient visits were collected in 2013. The numbers of daily ED patient visits were widely dispersed and positively skewed rather than symmetric and narrow with a normal distribution.

CONCLUSION

The daily variability of ED visit is too large and it did not show normal distribution. The average visit volume does not adequately represent ED operation.

The unannounced patient in the corridor: trust, friction and person-centered care

In this study, a Swedish cancer clinic was studied where three to four unscheduled patients sought support from the hospital on a daily basis for pain and nutrition problems. The clinic was neither staffed nor had a budget to handle such return visits. In order to offer the patients a better service and decrease the workload of the staff in addition to their everyday activities, a multidisciplinary team was established to address the unscheduled return visits. The team was supposed to involve the patient, build trust, decrease the friction, and contribute to a successful rehabilitation process. Data were collected from the patients and the staff. Patients who encountered the team (intervention) and patients who encountered the regular ad hoc type of organization (control) answered a questionnaire measuring trust and friction. Nurses in the control group spent 35% of their full-time employment, and the intervention group staffed with nurses spent 30% of their full-time employment in addressing the needs of these return patients. The patients perceived that trust between them and the staff was high. In summary, it was measured as being 4.48 [standard deviation (SD) = 0.82] in the intervention group and 4.41 (SD = 0.79) in the control group using the 5-point Likert scale. The data indicate that using a multidisciplinary team is a promising way to handle the problems of unannounced visits from patients. Having a team made it cost effective for the clinic and provided a better service than the traditional ad hoc organization. Copyright © 2015 John Wiley & Sons, Ltd.

The Long-Term Effect of an Independent Capacity Protocol on Emergency Department Length of Stay: A before and after Study

PURPOSE

In this study, we determined the long-term effects of the Independent Capacity Protocol (ICP), in which the emergency department (ED) is temporarily used to stabilize patients, followed by transfer of patients to other facilities when necessary, on crowding metrics.

MATERIALS AND METHODS

A before and after study design was used to determine the effects of the ICP on patient outcomes in an academic, urban, tertiary care hospital. The ICP was introduced on July 1, 2007 and the before period included patients presenting to the ED from January 1, 2005 to June 31, 2007. The after period began three months after implementing the ICP from October 1, 2007 to December 31, 2010. The main outcomes were the ED length of stay (LOS) and the total hospital LOS of admitted patients. The mean number of monthly ED visits and the rate of inter-facility transfers between emergency departments were also determined. A piecewise regression analysis, according to observation time intervals, was used to determine the effect of the ICP on the outcomes.

RESULTS

During the study period the number of ED visits significantly increased. The intercept for overall ED LOS after intervention from the before-period decreased from 8.51 to 7.98 hours [difference 0.52, 95% confidence interval (CI): 0.04 to 1.01] (p=0.03), and the slope decreased from -0.0110 to -0.0179 hour/week (difference 0.0069, 95% CI: 0.0012 to 0.0125) (p=0.02).

CONCLUSION

Implementation of the ICP was associated with a sustainable reduction in ED LOS and time to admission over a six-year period.

Frequent users of the emergency department services in the largest academic hospital in the Netherlands: a 5-year report

OBJECTIVE

To investigate the demographic and service characteristics, motive for consultation, and disposition of adult frequent users (FUs) of the largest academic hospital in the Netherlands over a 5-year period.

PATIENTS AND METHODS

This retrospective study included all patients aged 18 years and older visiting the emergency department (ED) during a 5-year period (2009-2013). Frequent ED use was defined as having four or more visits to the ED during a year. Patient and service characteristics, motive for consultation, and disposition were explored.

RESULTS

Frequent ED users represented 2% of all patients who visited the ED during 2009-2013 (8% of all ED consultations). On average, each FU visited the ED five times per year. Compared with nonfrequent users (NFUs), FUs were significantly less often self-referred, less frequently transported to the hospital by ambulance, received a lower urgency code upon arrival to the ED, and more often admitted to hospital than NFUs. Complaints related to the digestive system (19%), general complaints such as fever (18%), respiratory (10%), or cardiovascular problems (10%) were the main motive for consultations of the frequent ED users. Two percent of the FUs were serial FUs (FUs during 3 or more consecutive years).

CONCLUSION

Frequent use of the ED has been depicted as inappropriate use of these services. However, our study shows that FUs consist of a relatively small number of patients and that FUs suffer from chronic, and often, severe somatic illnesses that require specialized medical care.

Assuring Quality Health Care in the Emergency Department

The provision of quality healthcare is an international mandate. The provision of quality healthcare for mental health patients poses unique challenges. Nowhere is this challenge greater than in the emergency department. The purpose of this manuscript is to describe evidence-based initiatives for improving the quality of care of mental health patients in the emergency department. Specifically, the use of telepsychiatry and reducing provider biases will be presented.

ED crowding is associated with inpatient mortality among critically ill patients admitted via the ED: post hoc analysis from a retrospective study

BACKGROUND

Adverse effects of emergency department (ED) crowding among critically ill patients are not well known.

OBJECTIVES

We evaluated the association between ED crowding and inpatient mortality among critically ill patients admitted via the ED, and analyzed subsets of patients according to admission diagnosis.

METHODS

We performed a post hoc analysis using data from a previous retrospective study. We enrolled admitted patients via the ED with an initial systolic blood pressure of 90 mm Hg or lower when presenting to the ED. The ED occupancy ratio was used as a measure of crowding. The primary outcome was inpatient mortality. Multivariable logistic regression models adjusted for potential confounding variables were constructed for the entire cohort and for subsets according to admission diagnosis (infection, cardiac and vascular disease, trauma, gastrointestinal bleeding, and other factors).

RESULTS

A total of 1801 patients were enrolled, with a mortality rate of 14.6% (262 patients). The mortality rate by ED occupancy ratio quartile was 9.7% for the first quartile, 15.9% for the second quartile, 18.2% for the third quartile, and 14.4% for the fourth quartile. This resulted in adjusted odds ratios of 1.95, 2.51, and 1.93 and corresponding 95% confidence intervals of 1.23-3.12, 1.58-3.99, and 1.21-3.09 for the second, third, and fourth quartiles, respectively, compared with the first quartile. The effect of ED crowding was highest in the trauma subset, followed by the infection subset, whereas ED crowding did not appear to have any effect on the cardiac and vascular disease subsets.

CONCLUSION

Emergency department crowding was associated with increased inpatient mortality among critically ill patients admitted via the ED.

Review article: systematic review of three key strategies designed to improve patient flow through the emergency department

To explore the literature regarding three key strategies designed to promote patient throughput in the ED. CINAHL, Medline, PubMed, Scopus and Australian Government databases were searched for articles published between 1980 and 2014 using the key search terms ED flow/throughput, ED congestion, crowding, overcrowding, models of care, physician-assisted triage, medical assessment units, nurse practitioner, did not wait (DNW) and ED length of stay (LOS). Abstracts and articles not published in English and articles published before 1980 were excluded from the review. Quantitative and qualitative studies were considered for inclusion. The National Health Medical Research Council (NHMRC) Level of Evidence Hierarchy (2009) was applied to included studies. Twenty-one articles met criteria for review. The level of evidence assessed using the NHMRC guidelines of studies ranged from I to IV, with the majority falling into the Level II-2 (n = 6) and III-3 (n = 9) range. ED LOS was the outcome most often reported. Study quality was limited with few studies adjusting for confounding factors. Only one level I systematic review was included in this review. Advanced practice nursing roles, physician-assisted triage and medical assessment units are models of care that can positively impact ED throughput. They have been shown to decrease ED LOS and DNW rates. Confounding factors, such as site specific staffing requirements, patient acuity and rest-of-hospital processes, can also impact on patient throughput through the ED.

Skåne Emergency Department Assessment of Patient Load (SEAL)-A Model to Estimate Crowding Based on Workload in Swedish Emergency Departments

Objectives

Emergency department (ED) crowding is an increasing problem in many countries. The purpose of this study was to develop a quantitative model that estimates the degree of crowding based on workload in Swedish EDs.

Methods

At five different EDs, the head nurse and physician assessed the workload on a scale from 1 to 6 at randomized time points during a three week period in 2013. Based on these assessments, a regression model was created using data from the computerized patient log system to estimate the level of crowding based on workload. The final model was prospectively validated at the two EDs with the largest census.

Results

Workload assessments and data on 14 variables in the patient log system were collected at 233 time points. The variables Patient hours, Occupancy, Time waiting for the physician and Fraction of high priority (acuity) patients all correlated significantly with the workload assessments. A regression model based on these four variables correlated well with the assessed workload in the initial dataset (r2 = 0.509, p < 0.001) and with the assessments in both EDs during validation (r2 = 0.641; p < 0.001 and r2 = 0.624; p < 0.001).

Conclusions

It is possible to estimate the level of crowding based on workload in Swedish EDs using data from the patient log system. Our model may be applicable to EDs with different sizes and characteristics, and may be used for continuous monitoring of ED workload. Before widespread use, additional validation of the model is needed.

The hospital incident command system: modified model for hospitals in iran

INTRODUCTION

Effectiveness of hospital management of disasters requires a well-defined and rehearsed system. The Hospital Incident Command System (HICS), as a standardized method for command and control, was established in Iranian hospitals, but it has performed fairly during disaster exercises. This paper describes the process for, and modifications to HICS undertaken to optimize disaster management in hospitals in Iran.

METHODS

In 2013, a group of 11 subject matter experts participated in an expert consensus modified Delphi to develop modifications to the 2006 version of HICS.

RESULTS

The following changes were recommended by the expert panel and subsequently implemented: 1) A Quality Control Officer was added to the Command group; 2) Security was defined as a new section; 3) Infrastructure and Business Continuity Branches were moved from the Operations Section to the Logistics and the Administration Sections, respectively; and 4) the Planning Section was merged within the Finance/Administration Section.

CONCLUSION

An expert consensus group developed a modified HICS that is more feasible to implement given the managerial organization of hospitals in Iran. This new model may enhance hospital performance in managing disasters. Additional studies are needed to test the feasibility and efficacy of the modified HICS in Iran, both during simulations and actual disasters. This process may be a useful model for other countries desiring to improve disaster incident management systems for their hospitals.

Transfer of care and offload delay: continued resistance or integrative thinking?

The disciplines of paramedicine and emergency medicine have evolved synchronously over the past four decades, linked by emergency physicians with expertise in prehospital care. Ambulance offload delay (OD) is an inevitable consequence of emergency department overcrowding (EDOC) and compromises the care of the patient on the ambulance stretcher in the emergency department (ED), as well as paramedic emergency medical service response in the community. Efforts to define transfer of care from paramedics to ED staff with a view to reducing offload time have met with resistance from both sides with different agendas. These include the need to return paramedics to serve the community versus the lack of ED capacity to manage the patient. Innovative solutions to other system issues, such as rapid access to trauma teams, reducing door-to-needle time, and improving throughput in the ED to reduce EDOC, have been achieved by involving all stakeholders in an integrative thinking process. Only by addressing this issue in a similar integrative process will solutions to OD be realized.

Overcrowding in emergency department: an international issue

Overcrowding in the emergency department (ED) has become an increasingly significant worldwide public health problem in the last decade. It is a consequence of simultaneous increasing demand for health care and a deficit in available hospital beds and ED beds, as for example it occurs in mass casualty incidents, but also in other conditions causing a shortage of hospital beds. In Italy in the last 12-15 years, there has been a huge increase in the activity of the ED, and several possible interventions, with specific organizational procedures, have been proposed. In 2004 in the United Kingdom, the rule that 98 % of ED patients should be seen and then admitted or discharged within 4 h of presentation to the ED ('4 h rule') was introduced, and it has been shown to be very effective in decreasing ED crowding, and has led to the development of further acute care clinical indicators. This manuscript represents a synopsis of the lectures on overcrowding problems in the ED of the Third Italian GREAT Network Congress, held in Rome, 15-19 October 2012, and hopefully, they may provide valuable contributions in the understanding of ED crowding solutions.

Low acuity and general practice-type presentations to emergency departments: a rural perspective

OBJECTIVE

To estimate the number of general practice (GP)-type patients attending a rural ED and provide a comparative rural estimate to a metropolitan study.

METHODS

Analysis of presentations to the two EDs in Northwest Tasmania from 1 January 2009 to 31 December 2013 using the Diagnosis, Sprivulis, Australian College of Emergency Medicine (ACEM) and the Australian Institute of Health and Welfare (AIHW) methods to estimate the number of GP-type presentations.

RESULTS

There were 255,365 ED presentations in Northwest Tasmania during the study period. There were 86,973 GP-type presentations using the ACEM method, 142,006 using the AIHW method, 174,748 using the Diagnosis method and 28,922 low acuity patients identified using the Sprivulis method.

CONCLUSIONS

The proportion of GP-type presentations identified using the four methods ranged from 15% to 69%. The results suggest that triage status and self-referral are not reliable indicators of low acuity in this rural area. In rural areas with a shortage of GPs, it is likely that many people appropriately self-refer to ED because they cannot access a GP. The results indicate that the ACEM method might be most useful for identifying GP-type patients in rural ED. However, this requires validation in other regions of Australia.

Better performance on length-of-stay benchmarks associated with reduced risk following emergency department discharge: an observational cohort study

Introduction

Emergency department (ED) crowding is associated with adverse outcomes. Several jurisdictions have established benchmarks and targets for length-of-stay (LOS) to reduce crowding. An evaluation has been conducted on whether performance on Ontario’s ED LOS benchmarks is associated with reduced risk of death or hospitalization.

Methods

A retrospective cohort study of discharged ED patients was conducted using population-based administrative data from Ontario (April 2008 to February 2012). For each ED visit, the proportion of patients seen during the same shift that met ED LOS benchmarks was determined. Performance was categorized as <80%, 80% to <90%, 90% to <95%, and 95%–100% of same-shift ED patients meeting the benchmark. Logistic regression models analysed the association between performance on ED LOS benchmarks and 7-day death or hospitalization, controlled for patient and ED characteristics and stratified by patient acuity.

Results

From 122 EDs, 2,295,256 high-acuity and 1,626,629 low-acuity visits resulting in discharge were included. Deaths and hospitalizations within 7 days totalled 1,429 (0.062%) and 49,771 (2.2%) among high-acuity, and 220 (0.014%) and 9,005 (0.55%) among low-acuity patients, respectively. Adverse outcomes generally increased among patients seen during shifts when a lower proportion of ED patients met ED LOS benchmarks. The adjusted odds ratios (and 95% confidence intervals) among high- and low-acuity patients seen on shifts when <80% met ED benchmarks (compared with ≥95%) were, respectively, 1.32 (1.05–1.67) and 1.84 (1.21–2.81) for death, and 1.13 (1.08–1.17) and 1.40 (1.31–1.49) for hospitalization.

Conclusions

Better performance on Ontario’s ED LOS benchmarks for each shift is associated with a 10%–45% relative reduction in the odds of death or admission 7 days after ED discharge.

The boarding experience from the patient perspective: the wait

STUDY OBJECTIVE

We sought to better understand the experience of being a boarder patient.

METHODS

We conducted a qualitative study between March and August 2012 to examine the experience of boarding in an urban, teaching hospital emergency department (ED). We included boarder patients and selected patients based on a convenience sample. Interviews were semistructured, consisting of eight main open-ended questions. Interviews were transcribed; codes were generated and then organised into categorises and subsequently into one theme. We concluded analysis when we achieved thematic saturation. Our institutional review board approved this study.

RESULTS

Our final sample included 18 patients. The average age was 62.3 years. Patients characterised waiting as central to their experience as a boarder patient. One patient stated, "Well if you have to wait for a bed you have to wait for a bed, it's terrible." Three categories exemplified this waiting experience: (1) there was often lack of communication; (2) patients experienced frustration during this waiting period; and yet (3) patients often differentiated the experience of waiting from the care they were receiving.

CONCLUSIONS

Being a boarder patient was characterised as a waiting experience associated with poor communication and frustration. However, patients may still differentiate their feelings towards the wait from those towards the medical care they are receiving. Our data add more reason to eradicate the practice of ED boarding.

Providing Care in Emergency Department Hallways: Demands, Dangers, and Deaths

Emergency departments (ED) worldwide have experienced dramatic increases in crowding over the past 20 years that now have reached critical levels. One consequence of ED crowding has been the routine use of ED hallways for patient care. This includes ED patients who are awaiting care but are considered unstable to remain in the waiting room, patients who are undergoing active medical and trauma treatment, and patients who have been stabilized but await transfer to an inpatient bed (boarding) or another institution. Compared with licensed hospital or standard ED beds, care in ED hallways results in increased patient morbidity and mortality, as well as patient and staff dissatisfaction. Complications experienced by hallway patients include unrecognized sudden respiratory arrest or unstable cardiac arrhythmias, delay in time-sensitive procedures and laboratory testing, delay in receiving important medications, excessive or unrelieved pain, overall increased length of stay, increased disability, and exposure to traumatic psychological events. While much has been published on the general problems of ED crowding, only recently have studies focused exclusively on the issues of providing care in ED hallways. This review summarizes the current issues, challenges, and solutions for hallway care.

Determinants of non-urgent Emergency Department attendance among females in Qatar

BACKGROUND

The use of emergency department (ED) services for non-urgent conditions is well-studied in many Western countries but much less so in the Middle East and Gulf region. While the consequences are universal-a drain on ED resources and poor patient outcomes-the causes and solutions are likely to be region and country specific. Unique social and economic circumstances also create gender-specific motivations for patient attendance. Alleviating demand on ED services requires understanding these circumstances, as past studies have shown. We undertook this study to understand why female patients with low-acuity conditions choose the emergency department in Qatar over other healthcare options.

SETTING AND DESIGN

Prospective study at Hamad General Hospital's (HGH) emergency department female "see-and-treat" unit that treats low-acuity cases. One hundred female patients were purposively recruited to participate in the study. Three trained physicians conducted semi-structured interviews with patients over a three-month period after they had been treated and given informed consent.

RESULTS

The study found that motivations for ED attendance were systematically influenced by employment status as an expatriate worker. Forty percent of the sample had been directed to the ED by their employers, and the vast majority (89%) of this group cited employer preference as the primary reason for choosing the ED. The interviews revealed that a major obstacle to workers using alternative facilities was the lack of a government-issued health card, which is available to all citizens and residents at a nominal rate.

CONCLUSION

Reducing the number of low-acuity cases in the emergency department at HGH will require interventions aimed at encouraging patients with non-urgent conditions to use alternative healthcare facilities. Potential interventions include policy changes that require employers to either provide workers with a health card or compel employees to acquire one for themselves.

Perspectives of patients with acute abdominal pain in an emergency department observation unit and a surgical assessment unit: a prospective comparative study

AIMS AND OBJECTIVES

To investigate the patient perspective when admitted with acute abdominal pain to an emergency department observation unit compared with the perspective when admitted to a surgical assessment unit.

BACKGROUND

An increase in emergency department observation units has led to more short-term admissions and has changed the patient journey from admission to specialised wards staffed by specialist nurses to stays in units staffed by emergency nurses.

DESIGN

A comparative field study.

METHODS

The study included 21 patients. Participant observation and qualitative interviews were performed, and the analyses were phenomenological-hermeneutic.

RESULTS

Emergency department observation unit patients had extensive interaction with health professionals, which could create distrust. Surgical assessment unit patients experienced lack of interaction with nurses, also creating distrust. Emergency department observation unit patients had more encounters with fellow patients than the surgical assessment unit patients did, which was beneficial when needing assistance, but disturbing when needing rest. The limited contact with other patients in the surgical assessment unit revealed the opposite effect. In both units, there was nonpersonalised care, making it difficult for patients to make informed decisions.

CONCLUSION

The multibedded rooms in the emergency department observation unit had a positive influence on patient–nurse interaction, but a negative influence on privacy; the opposite was found in the surgical assessment unit with its rooms with fewer beds. The extensive professional–patient interactions in the emergency department observation unit created distrust. The limited professional–patient interaction in the surgical assessment unit did the same. That the emergency department observation unit was staffed by emergency nurses seemed to have a positive influence on the length of patient–nurse interactions, while the surgical assessment unit staffed by specialist nurses seemed to have the opposite effect. There was lack of information and personalised care in both units.

RELEVANCE TO CLINICAL PRACTICE

Units receiving acute patients need to provide personalised care and information about how the unit functions and about care and treatment to improve the patients' ability to make decisions during admission.

Detecting child abuse based on parental characteristics: does the Hague Protocol cause parents to avoid the emergency department?

OBJECTIVES

The Hague Protocol is used by professionals at the adult Emergency Departments (ED) in The Netherlands to detect child abuse based on three parental characteristics: (1) domestic violence, (2) substance abuse or (3) suicide attempt or self-harm. After detection, a referral is made to the Reporting Center for Child Abuse and Neglect (RCCAN). This study investigates whether implementing this Protocol will lead parents to avoid medical care.

METHOD

We compared the number of patients (for whom the Protocol applied) who attended the ED prior to implementation with those attending after implementation. We conducted telephone interviews (n = 14) with parents whose children were referred to the RCCAN to investigate their experience with the procedure.

RESULTS

We found no decline in the number of patients, included in the Protocol, visiting the ED during the 4 year implementation period (2008-2011). Most parents (n = 10 of the 14 interviewed) were positive and stated that they would, if necessary, re-attend the ED with the same complaints in the future.

CONCLUSION

ED nurses and doctors referring children based on parental characteristics do not have to fear losing these families as patients.

Comparative effectiveness of physician diagnosis and guideline definitions in identifying sepsis patients in the emergency department

PURPOSE

The purpose of our study was to compare the agreement of emergency physician diagnoses relative to the 1991 American College of Chest Physicians (ACCP)/Society of Critical Care Medicine (SCCM) and 2001 ACCP/SCCM/European Society of Intensive Care Medicine/American Thoracic Society/Surgical Infection Society internationally accepted definitions of sepsis, severe sepsis, and septic shock.

MATERIALS AND METHODS

This study was an observational cohort study of adult patients presenting to the emergency department (ED) with a chief complaint suggestive of infection over a 6-week period, during a daily enrollment schedule from 7:00 am to 10:00 pm. Patients were categorized as having "no sepsis," "sepsis," "severe sepsis," or "septic shock" based on ED physician diagnosis, the 1991 definitions, or 2001 definitions. Agreement statistics were performed.

RESULTS

A total of 1275 patients were enrolled with age 50.1 ± 21.7 years and 59.1% were female. Among the enrolled patients, 228 were identified as having a source of infection. Temperature, heart rate, and white blood cell count were significantly higher in patients with infection, compared with those without (P < .001). The odds ratio for disagreement between a physician-designated no sepsis diagnosis and the 1991 definitions was 4.47 (95% confidence interval, 3.01-7.53) and 5.96 (3.78-9.46) between the same physician-designated diagnosis and the 2001 definitions. The odds ratios for disagreement of a severe sepsis physician diagnosis in relation to the 1991 and 2001 definitions were 0.06 (0.01-0.19) and 0.06 (0.01-0.20), respectively. The 1991 and 2001 consensus definitions had strong agreement, with κ = 0.86 and 91.2% agreement. No agreement was found between the physician diagnosis and 1991 consensus sepsis definitions (κ = 0.11 and 52.2% agreement) or between the physician diagnosis and the 2001 consensus sepsis definitions (κ = 0.13 and 50.0% agreement).

CONCLUSIONS

Our study showed that ED physician diagnosis of sepsis may disagree with the international definitions such that severe sepsis is underrecognized by clinical judgment alone. Although these results are limited to a single center, we raise concern that early treatments for these high-risk patients may be delayed due to inaccurate clinical diagnosis. Efforts are needed to increase the application of sepsis guideline definitions to better identify ED patients with this potentially deadly condition.

[Interdisciplinary emergency room - key to success?]

In Germany, which is also faced with a scarcity of resources, the concept of central, interdisciplinary emergency rooms ("Zentrale Notfallaufnahme", ZNA) is being developed as an answer to the complex demands of modern emergency medicine with increasing numbers of patients and complexity of the medical conditions. This autonomous institution is the first point of contact for all emergency patients. The central tasks of the ZNA are triage and the interdisciplinary primary treatment of patients. The establishment of the ZNA includes specific facilities (treatment rooms, short stay units, resuscitation rooms, triage and management areas, integration of the premises on site) as well as specific processes (triage systems, specific standard operating procedures) and training for the staff (European Curriculum for Emergency Medicine). It could be shown that by establishing a ZNA along with all its structures the satisfaction of the patients (including shorter waiting times), resource management (intensive care capacity), and patient outcome could be significantly improved.

Using discrete event computer simulation to improve patient flow in a Ghanaian acute care hospital

OBJECTIVES

Crowding and limited resources have increased the strain on acute care facilities and emergency departments worldwide. These problems are particularly prevalent in developing countries. Discrete event simulation is a computer-based tool that can be used to estimate how changes to complex health care delivery systems such as emergency departments will affect operational performance. Using this modality, our objective was to identify operational interventions that could potentially improve patient throughput of one acute care setting in a developing country.

METHODS

We developed a simulation model of acute care at a district level hospital in Ghana to test the effects of resource-neutral (eg, modified staff start times and roles) and resource-additional (eg, increased staff) operational interventions on patient throughput. Previously captured deidentified time-and-motion data from 487 acute care patients were used to develop and test the model. The primary outcome was the modeled effect of interventions on patient length of stay (LOS).

RESULTS

The base-case (no change) scenario had a mean LOS of 292 minutes (95% confidence interval [CI], 291-293). In isolation, adding staffing, changing staff roles, and varying shift times did not affect overall patient LOS. Specifically, adding 2 registration workers, history takers, and physicians resulted in a 23.8-minute (95% CI, 22.3-25.3) LOS decrease. However, when shift start times were coordinated with patient arrival patterns, potential mean LOS was decreased by 96 minutes (95% CI, 94-98), and with the simultaneous combination of staff roles (registration and history taking), there was an overall mean LOS reduction of 152 minutes (95% CI, 150-154).

CONCLUSIONS

Resource-neutral interventions identified through discrete event simulation modeling have the potential to improve acute care throughput in this Ghanaian municipal hospital. Discrete event simulation offers another approach to identifying potentially effective interventions to improve patient flow in emergency and acute care in resource-limited settings.

Cardiac biomarkers for infarct diagnosis and early exclusion of acute coronary syndrome

The acute coronary syndrome (ACS) represents a diagnostic challenge: on the one hand patients need to be quickly identified to initiate treatment and on the other hand early exclusion of patients without ACS is important to relieve patient stress as well as overcrowded emergency departments. A growing number of biomarkers are becoming available to aid physicians with this task. This review gives an overview of the current research concerning early exclusion with an emphasis on the clinically most important biomarker: cardiac troponin.

Evaluation of an emergency department lean process improvement program to reduce length of stay

STUDY OBJECTIVE

In recent years, lean principles have been applied to improve wait times in the emergency department (ED). In 2009, an ED process improvement program based on lean methods was introduced in Ontario as part of a broad strategy to reduce ED length of stay and improve patient flow. This study seeks to determine the effect of this program on ED wait times and quality of care.

METHODS

We conducted a retrospective cohort study of all ED visits at program and control sites during 3 program waves from April 1, 2007, to June 30, 2011, in Ontario, Canada. Time series analyses of outcomes before and after the program and difference-in-differences analyses comparing changes in program sites with control sites were conducted.

RESULTS

In before-after models among program sites alone, 90th percentile ED length of stay did not change in wave 1 (-14 minutes [95% confidence interval {CI} -47 to 20]) but decreased after wave 2 (-87 [95% CI -108 to -66]) and wave 3 (-33 [95% CI -50 to -17]); median ED length of stay decreased after wave 1 (-18 [95% CI -24 to -12]), wave 2 (-23 [95% CI -27 to -19]), and wave 3 (-15 [95% CI -18 to -12]). In all waves, decreases were observed in time to physician assessment, left-without-being-seen rates, and 72-hour ED revisit rates. In the difference-in-difference models, in which changes in program sites were compared with controls, the program was associated with no change in 90th percentile ED length of stay in wave 2 (17 [95% CI -0.2 to 33]) and increases in wave 1 (23 [95% CI 0.9 to 45]) and wave 3 (31 [95% CI 10 to 51]), modest reductions in median ED length of stay in waves 2 and 3 alone, and a decrease in time to physician assessment in wave 3 alone.

CONCLUSION

Although the program reduced ED waiting times, it appeared that its benefits were diminished or disappeared when compared with that of control sites, which were exposed to system-wide initiatives such as public reporting and pay for performance. This study suggests that further evaluation of the effectiveness of lean methods in the ED is warranted before widespread implementation.

Primary care referrals of patients with potentially serious diseases to the emergency department or a quick diagnosis unit: a cross-sectional retrospective study

BACKGROUND

In Spain, primary healthcare (PHC) referrals for diagnostic procedures are subject to long waiting-times, and physicians and patients often use the emergency department (ED) as a shortcut. We aimed to determine whether patients evaluated at a hospital outpatient quick diagnosis unit (QDU) who were referred to ED from 12 PHC centers could have been directly referred to QDU, thus avoiding ED visits. As a secondary objective, we determined the proportion of QDU patients who might have been evaluated in a less rapid, non-QDU setting.

METHODS

We carried out a cross-sectional retrospective cohort study of patients with potentially serious conditions attended by the QDU from December 2007 to December 2012. We established 2 groups of patients: 1) patients referred from PHC to QDU (PHC-QDU group) and 2) patients referred from PHC to ED, then to QDU (PHC-ED-QDU group). Two observers assessed the appropriateness/inappropriateness of each referral using a scoring system. The interobserver agreement was assessed by calculating the kappa index. Multivariate logistic regression analysis was performed to identify the factors associated with the dependent variable 'ED referral'.

RESULTS

We evaluated 1186 PHC-QDU and 1004 PHC-ED-QDU patients and estimated that 93.1% of PHC-ED-QDU patients might have been directly referred to QDU. In contrast, 96% of PHC-QDU patients were found to be appropriately referred to QDU first. The agreement for PHC-QDU referrals (PHC-QDU group) was rated as excellent (ϰ=0.81), while it was rated as good for PHC-ED referrals (PHC-ED-QDU group) (ϰ=0.75). The mean waiting-time for the first QDU visit was longer in PHC-QDU (4.8 days) than in PHC-ED-QDU (2.6 days) patients (P=.001). On multivariate analysis, anemia (OR 2.87, 95% CI 1.49-4.55, P<.001), rectorrhagia (OR 2.18, 95% CI 1.10-3.77, P=.01) and febrile syndrome (OR 2.53, 95% CI 1.33-4.12, P=.002) were independent factors associated with ED referral. Nearly one-fifth of all QDU patients were found who might have been evaluated in a less rapid, non-QDU setting.

CONCLUSIONS

Most PHC-ED-QDU patients might have been directly referred to QDU from PHC, avoiding the inconvenience of the ED visit. A stricter definition of QDU evaluation criteria may be needed to improve and hasten PHC referrals.

"Not so fast!" the complexity of attempting to decrease door-to-floor time for emergency department admissions

BACKGROUND

Successful quality improvement is fundamental to high-performing health care systems, but becomes increasingly difficult as systems become more complex. Previous attempts at the University of California, San Francisco (UCSF) Medical Center to reduce door-to-floor (D2F) time -the time required to move an ill patient through the emergency department (ED) to an appropriate inpatient bed-had not resulted in meaningful improvement. An analysis of why attempts at decreasing D2F times in the ED had failed, with attention to contextual factors, yields recommendations on how to decrease D2F time.

METHODS

A team of 11 internal medicine residents, in partnership with the Patient Flow Executive Steering Committee, performed a literature review, process mapping, and analysis of the admissions process. The team conducted interviews with medical center staff across disciplines, members of high-performing patient care units, and leaders of peer institutions who had undertaken similar efforts.

FINDINGS AND RECOMMENDATIONS

Each of the following three domains-(1) Improving Work Flow, (2) Changing Culture, and (3) Understanding Incentives-is independently an important source of resistance and opportunity. However, the improvement work and understanding of complexity science suggest that all three domains must be addressed simultaneously to effect meaningful change. Recommendations include eliminating redundant and frustrating processes; encouraging multidisciplinary collaboration; fostering trust between departments; providing feedback on individual performance; enhancing provider buy-in; and, ultimately, uniting staff behind a common goal.

CONCLUSION

By conceptualizing the hospital as a complex adaptive system, multiple interrelated groups can be encouraged to work together and accomplish a common goal.

Reasons for non-urgent presentations to the emergency department in Saudi Arabia

BACKGROUND

The majority of patients who attend emergency departments (EDs) in Saudi Arabia have non-urgent problems, resulting in overcrowding, excessive waiting times and delayed care for more acutely ill patients. The purpose of this research was to examine the reasons for non-urgent visits to a Saudi ED and factors associated with patient perceptions of urgency.

METHODS

We administered a survey to 350 consecutively presenting Canadian Triage and Acuity Scale (CTAS) IV or V adult patients at a large tertiary ED in Riyadh region, Saudi Arabia, during 25 days of data collection in March 2013.

RESULTS

Over half of the sample usually visited the ED to access healthcare. The most common reasons for attending the ED were not having a regular healthcare provider (63%), being able to receive care on the same day (62%), and the convenience of and access to medical care 24/7 (62%). Approximately two-thirds of CTAS V patients and one-third of CTAS IV patients believed their conditions were more urgent than their triage nurse rating.

CONCLUSION

Multiple factors influence non-urgent visits to the ED in the Saudi context including insufficient community awareness of the role of the ED and perceived lack of access to primary healthcare services.

An electronic alert for HIV screening in the emergency department increases screening but not the diagnosis of HIV

OBJECTIVE

Based on US. Centers for Disease Control and Prevention recommendations, New York State enacted legislation in 2010 requiring healthcare providers to offer non-targeted human immunodeficiency virus (HIV) testing to all patients aged 13-64. Three New York City adult emergency departments implemented an electronic alert that required clinicians to document whether an HIV test was offered before discharging a patient. The purpose of this study was to assess the impact of the electronic alert on HIV testing rates and diagnosis of HIV positive individuals.

METHODS

During the pre-intervention period (2.5-4 months), an electronic "HIV Testing" order set was available for clinicians to order a test or document a reason for not offering the test (e.g., patient is not conscious). An electronic alert was then added to enforce completion of the order set, effectively preventing ED discharge until an HIV test was offered to the patient. We analyzed data from 79,786 visits, measuring HIV testing and detection rates during the pre-intervention period and during the six months following the implementation of the alert.

RESULTS

The percentage of visits where an HIV test was performed increased from 5.4% in the preintervention period to 8.7% (p<0.001) after the electronic alert. After the implementation of the electronic alert, there was a 61% increase in HIV tests performed per visit. However, the percentage of patients testing positive per total patients-tested was slightly lower in the post-intervention group than the pre-intervention group (0.48% vs. 0.55%), but this was not significant. The number of patients-testing positive per total-patient visit was higher in the post-intervention group (0.04% vs. 0.03%).

CONCLUSIONS

An electronic alert which enforced non-targeted screening was effective at increasing HIV testing rates but did not significantly increase the detection of persons living with HIV. The impact of this electronic alert on healthcare costs and quality of care merits further examination.

National ED crowding and hospital quality: results from the 2013 Hospital Compare data

OBJECTIVES

We explored Hospital Compare data on emergency department (ED) crowding metrics to assess characteristics of reporting vs nonreporting hospitals, whether hospitals ranked as the US News Best Hospitals (2012-2013) vs unranked hospitals differed in ED performance and relationships between ED crowding and other reported hospital quality measures.

METHODS

An ecological study was conducted using data from Hospital Compare data sets released March 2013 and from a popular press publication, US News Best Hospitals 2012 to 2013. We compared hospitals on 5 ED crowding measures: left-without-being-seen rates, waiting times, boarding times, and length of stay for admitted and discharged patients.

RESULTS

Of 4810 hospitals included in the Hospital Compare sample, 2990 (62.2%) reported all ED 5 crowding measures. Median ED length of stay for admitted patients was 262 minutes (interquartile range [IQR], 215-326), median boarding was 88 minutes (IQR, 60-128), median ED length of stay for discharged patients was 139 minutes (IQR, 114-168), and median waiting time was 30 minutes (IQR, 20-44). Hospitals ranked as US News Best Hospitals 2012 to 2013 (n=650) reported poorer performance on ED crowding measures than unranked hospitals (n=4160) across all measures. Emergency department boarding times were associated with readmission rates for acute myocardial infarction (r=0.14, P<.001) and pneumonia (r=0.17, P<.001) as well as central line-associated bloodstream infections (r=0.37, P<.001).

CONCLUSIONS

There is great variation in measures of ED crowding across the United States. Emergency department crowding was related to several measures of in-patient quality, which suggests that ED crowding should be a hospital-wide priority for quality improvement efforts.

The relationship between emergency department crowding and patient outcomes: a systematic review

PURPOSE

Emergency department (ED) crowding is a significant patient safety concern associated with poor quality of care. The purpose of this systematic review is to assess the relationship between ED crowding and patient outcomes.

DESIGN

We searched the Medline search engine and relevant emergency medicine and nursing journals for studies published in the past decade that pertained to ED crowding and the following patient outcome measures: mortality, morbidity, patient satisfaction, and leaving the ED without being seen. All articles were appraised for study quality.

FINDINGS

A total of 196 abstracts were screened and 11 articles met inclusion criteria. Three of the eleven studies reported a significant positive relationship between ED crowding and mortality either among patients admitted to the hospital or discharged home. Five studies reported that ED crowding is associated with higher rates of patients leaving the ED without being seen. Measures of ED crowding varied across studies.

CONCLUSIONS

ED crowding is a major patient safety concern associated with poor patient outcomes. Interventions and policies are needed to address this significant problem.

CLINICAL RELEVANCE

This review details the negative patient outcomes associated with ED crowding. Study results are relevant to medical professionals and those that seek care in the ED.

Effects of multidisciplinary teamwork on lead times and patient flow in the emergency department: a longitudinal interventional cohort study

BACKGROUND

Long waiting times for emergency care are claimed to be caused by overcrowded emergency departments and non-effective working routines. Teamwork has been suggested as a promising solution to these issues. The aim of the present study was to investigate the effects of teamwork in a Swedish emergency department on lead times and patient flow.

METHODS

The study was set in an emergency department of a university hospital where teamwork, a multi-professional team responsible for the whole care process for a group of patients, was introduced. The study has a longitudinal non-randomized intervention study design. Data were collected for five two-week periods during a period of 1.5 years. The first part of the data collection used an ABAB design whereby standard procedure (A) was altered weekly with teamwork (B). Then, three follow-ups were conducted. At last follow-up, teamwork was permanently implemented. The outcome measures were: number of patients handled within teamwork time, time to physician, total visit time and number of patients handled within the 4-hour target.

RESULTS

A total of 1,838 patient visits were studied. The effect on lead times was only evident at the last follow-up. Findings showed that the number of patients handled within teamwork time was almost equal between the different study periods. At the last follow-up, the median time to physician was significantly decreased by 11 minutes (p = 0.0005) compared to the control phase and the total visit time was significantly shorter at last follow-up compared to control phase (p = <0.0001; 39 minutes shorter on average). Finally, the 4-hour target was met in 71% in the last follow-up compared to 59% in the control phase (p = 0.0005).

CONCLUSIONS

Teamwork seems to contribute to the quality improvement of emergency care in terms of small but significant decreases in lead times. However, although efficient work processes such as teamwork are necessary to ensure safe patient care, it is likely not sufficient for bringing about larger decreases in lead times or for meeting the 4-hour target in the emergency department.

Emergency department crowding in The Netherlands: managers' experiences

Background

In The Netherlands, the state of emergency department (ED) crowding is unknown. Anecdotal evidence suggests that current ED patients experience a longer length of stay (LOS) compared to some years ago, which is indicative of ED crowding. However, no multicenter studies have been performed to quantify LOS and assess crowding at Dutch EDs. We performed this study to describe the current state of emergency departments in The Netherlands regarding patients’ length of stay and ED nurse managers’ experiences of crowding.

Methods

A survey was sent to all 94 ED nurse managers in The Netherlands with questions regarding the type of facility, annual ED census, and patients’ LOS. Additional questions included whether crowding was ever a problem at the particular ED, how often it occurred, which time periods had the worst episodes of crowding, and what measures the particular ED had undertaken to improve patient flow.

Results

Surveys were collected from 63 EDs (67%). Mean annual ED visits were 24,936 (SD ± 9,840); mean LOS for discharged patients was 119 (SD ± 40) min and mean LOS for admitted patients 146 (SD ± 49) min. Consultation delays, laboratory and radiology delays, and hospital bed shortages for patients needing admission were the most cited reasons for crowding. Admitted patients had a longer LOS because of delays in obtaining inpatient beds. Thirty-nine of 57 respondents (68%) reported that crowding occurred several times a week or even daily, mostly between 12:00 and 20:00. Measures taken by hospitals to manage crowding included placing patients in hallways and using fasttrack with treatment of patients by trained nurse practitioners.

Conclusions

Despite a relatively short LOS, frequent crowding appears to be a nationwide problem according to Dutch ED nurse managers, with 68% of them reporting that crowding occurred several times a week or even daily. Consultations delays, laboratory and radiology delays, and hospital bed shortage for patients needing admission were believed to be the most important factors contributing to ED crowding.

Emergency department use by oldest-old patients from 2005 to 2010 in a Swiss university hospital

Background

Aging of the population in all western countries will challenge Emergency Departments (ED) as old patients visit these health services more frequently and present with special needs. The aim of this study is to describe the trend in ED visits by patients aged 85 years and over between 2005 and 2010, and to compare their service use to that of patients aged 65–84 years during this period and to investigate the evolution of these comparisons over time.

Methods

Data considered were all ED visits to the University of Lausanne Medical Center (CHUV), a tertiary Swiss teaching hospital, between 2005 and 2010 by patients aged 65 years and over (65+ years). ED visit characteristics were described according to age group and year. Incidence rates of ED visits and length of ED stay were calculated.

Results

Between 2005 and 2010, ED visits by patients aged 65 years and over increased by 26% overall, and by 46% among those aged 85 years and over (85+ years). Estimated ED visit incidence rate for persons aged 85+ years old was twice as high as for persons aged 65–84 years. Compared to patients aged 65–84 years, those aged 85+ years were more likely to be hospitalized and have a longer ED stay. This latter difference increased over time between 2005 and 2010.

Conclusions

Oldest-old patients are increasingly using ED services. These services need to adapt their care delivery processes to meet the needs of a rising number of these complex, multimorbid and vulnerable patients.

Emergency department boarding times for patients admitted to intensive care unit: Patient and organizational influences

INTRODUCTION

Critically ill patients can be subject to prolonged stays in the emergency department following receipt of an order to admit to an intensive care unit. The purpose of this study was to explore patient and organizational influences on the duration of boarding times for intensive care bound patients.

METHODS

This exploratory descriptive study was situated in a Canadian hospital in northern Ontario. Through a six-month retrospective review of three data sources, information was collected pertaining to 16 patient and organizational variables detailing the emergency department boarding time of adults awaiting transfer to the intensive care unit. Data analysis involved descriptive and non-parametric methods.

RESULTS

The majority of the 122 critically ill patients boarded in the ED were male, 55 years of age or older, arriving by ground ambulance on a weekday, and had an admitting diagnosis of trauma. The median boarding time was 34 min, with a range of 0-1549 min. Patients designated as most acute, intubated, and undergoing multiple diagnostic procedures had statistically significantly shorter boarding times.

DISCUSSION

The study results provide a profile that may assist clinicians in understanding the complex and site-specific interplay of variables contributing to boarding of critically ill patients.

The potential lost hospital income from miscoded emergency department boarders in Ireland

BACKGROUND

Emergency department (ED) boarders, namely patients who have been admitted under an in-patient service but remain on a trolley in the ED, have long been a problem in the Irish healthcare system.

METHODS

We conducted a retrospective analysis of all ED boarders in Cork University Hospital (CUH) for a 6-month period from January to July 2011. Data were obtained from the Hospital In-Patient Enquiry Office (HIPE). The income generated by the hospital for a subset of these patients (January and February attendances) was obtained from the Finance Office in the hospital, based on diagnoses as recorded on the HIPE system. A convenience sample of two-thirds of the 39 acute hospitals nationally was surveyed to ascertain whether ED boarders were coded by individual HIPE offices as hospital in-patients or as ED attendees.

RESULTS

A total of 806 patients were admitted to an in-patient service from January to July 2011 in CUH and subsequently discharged, having completed their entire stay in the ED. The income generated by a sub-sample of 228 patients (January and February ED boarders) was determined. The hospital was remunerated by <euro>685,111 for these patients, i.e. an average income of <euro>3,098 per patient. Only 8 hospitals of the 27 surveyed hospitals coded overnight ED Boarders as in-patients and were thus able to request income for these patients appropriately.

CONCLUSION

Discrepancies in coding of ED boarders may result in significant revenue losses for certain hospitals.

[Validity of admission diagnoses as process-driving criteria : influence on length of stay and consultation rate in emergency departments]

BACKGROUND

Primary care physicians and specialists often refer patients to the emergency department with a specific diagnosis and request for admission. Such an external diagnosis frequently influences the initial evaluation in the emergency department. The present study aimed to evaluate the accuracy of such external diagnoses and to assess the consequences of incorrect diagnoses on length of stay and number of specialty consultations in the emergency department.

MATERIAL AND METHODS

This was a prospective observational study over the course of 3 months in the emergency department of a tertiary care center. External admission diagnoses made by primary care physicians and specialists were categorized as "accurate", "partially accurate" and "inaccurate". A special analysis of the external admission diagnosed was performed for patients admitted directly to an intermediary care unit and intensive care unit or patients who were transferred directly from the emergency department to the operating room.

RESULTS

Data for 784 patients were analyzed. Patients were on average 63.1 ± 19.5 years old (minimum-maximum 18-97 years, median 68 years) and 54 % were male. After emergency department evaluation and treatment 57.8 % of external diagnoses were categorized as accurate, 23.6 % as partially accurate and 18.6 % as inaccurate. Patients with partially accurate and inaccurate diagnoses had a 3 and 6.5 times higher rate of specialty consultations in the emergency department, respectively, when compared with patients with an accurate diagnosis (number of specialty consultations n = 0: 77.3 % vs. 54.1 % vs. 92.9 %, p < 0.05; n = 1: 20.0 % vs. 40.4 % vs. 6.2 %, p < 0.05; n = 2: 2.7 % vs. 5.5 % vs. 0.9 %, p < 0.05, respectively. Patients with an accurate diagnosis had a shorter total length of stay than patients with a partially accurate or inaccurate diagnosis [mean ± SD (min-max; median): 192 ± 108 min (10-707 min; 181 min) vs. 246 ± 126 min (27-1,026 min; 214 min) vs. 258 ± 138 min (22-700 min; 232 min), p < 0.001], respectively. Out of 85 patients admitted directly to an intermediary care unit, intensive care unit and patients who were transferred directly from the emergency department to the operating room the diagnosis was accurate, partially accurate and inaccurate in 56.5 %, 24.7 % and 18.8 %, respectively.

CONCLUSIONS

Admission diagnoses made by primary care physicians and specialists who subsequently refer patients to the emergency department are subject to certain inaccuracies. Inaccurate admission diagnoses are associated with an increased length of stay and a considerably higher rate of specialty consultation in the emergency department. Standardized operating procedures, treatment algorithms and triage systems are important to identify such incorrect diagnoses so that these patients can undergo appropriate diagnostic investigation and treatment.

Measuring emergency department crowding in an inner city hospital in The Netherlands

Background

Overcrowding in the emergency department (ED) is an increasing problem worldwide. In The Netherlands overcrowding is not a major issue, although some urban hospitals struggle with increased throughput. In 2004, Weiss et al. created the NEDOCS tool (National Emergency Department Over Crowding Study), a web-based instrument to measure objective overcrowding with scores between 0 (not busy at all) to above 181 (disaster). In this study we tried to validate the accuracy of the NEDOCS tool by comparing this with the subjective feelings of the ED nurse and emergency physician (EP) in an inner city hospital in The Netherlands.

Methods

In a 4-week period, data of a total of 147 time samplings were collected. The subjective feelings of being overcrowded and feeling rushed by the ED nurse and EP were scored on a survey using a 6-point Likert scale on answering the question of how busy they would say the ED is right now. NEDOCS tool scores were calculated, and these were compared with the subjective feelings using the kappa statistic assessing linear weights according to Cohen’s method.

Results

Of all the time samplings, approximately 80% of the surveys were completed. The ED was rated as overcrowded 9% of the time by the ED nurses and 11% of the time by the EPs. The median NEDOCS score was 37 (0 to 120) and scored as overcrowded in 3%. There was a good intrarater agreement for the ED nurse and EP for the feeling of overcrowding and feeling of being rushed (κ = 0.79 and 0.73, respectively); the interrater agreement was moderate (κ = 0.53 and 0.43, respectively). The agreement between the NEDOCS and the subjective variables was moderate (κ = 0.50 and 0.53, respectively). A composite variable was created as the average of both the scores of feeling overcrowded of the nurse and the EP and the score of the EP of feeling rushed. The agreement between this and the NEDOCS was κ = 0.53.

Conclusions

The NEDOCS tool is a reasonably good tool to quantify the subjective feelings of overcrowding. When overcrowding is encountered and immediately recognised, specific measures can be taken to guarantee the timely provision of necessary medical care to the patients in the ED at that time. However, possibly more accurate agreements could be obtained as approximately 20% of the surveys were not completed because of perceived crowdedness. An important limitation is that only 3% of the NEDOCS is scored as overcrowded, so no conclusions can be drawn about the agreement for higher categories of overcrowding. It is suggested to repeat the study in a busier period. As the triage category was not taken into account in the formula, a high workload with only a few patients giving high scores in subjective overcrowding in spite of a low NEDOCS score could have led to lower agreements. Incorporating the triage category in the NEDOCS tool possibly will lead to better agreement, but further research is needed to assess this idea.

Analysis of three advanced practice roles in emergency nursing

BACKGROUND

There are many Emergency Department (ED) demand management systems that include advanced practice emergency nursing roles. The aim of this study is to examine and compare three advanced emergency nursing practice roles: ED Fast Track, Clinical Initiatives Nurse (CIN) and Rapid Intervention and Treatment Zone (RITZ).

METHOD

A descriptive exploratory approach was used to conduct this study at an urban district hospital in Melbourne, Australia. The study participants were patients managed in each of the three systems with advanced practice emergency nursing roles: Fast Track, CIN and RITZ.

RESULTS

There were a total of 551 patients: 195 Fast Track patients, 163 CIN managed patients and 193 RITZ patients. CIN managed patients were older (p<0.001), with higher levels of clinical urgency (p<0.001), and higher hospital admission rates (p<0.001). CIN managed patients had shorter waiting time for nursing care (p=0.001) and lower incidence of medical assessment within the time associated with their triage category (p<0.0001). ED LOS for discharged patients was significantly longer for CIN managed patients (p<0.001). CIN managed patients had a significantly higher incidence of electrocardiography (p<0.001), blood glucose measurement (p<0.001), intravenous cannulation (p<0.001), pathology testing (p<0.001), and analgesia administration (p<0.001) when compared to Fast Track and RITZ patients.

CONCLUSIONS

Advanced practice roles in emergency nursing can have different applications in the ED context. Clarity about role intent and scope of practice is important and should inform educational preparation and teams within which these roles operate.

Evolving prehospital, emergency department, and "inpatient" management models for geriatric emergencies

Alternative management methods are essential to ensure high-quality and efficient emergency care for the growing number of geriatric adults worldwide. Protocols to support early condition-specific treatment of older adults with acute severe illness and injury are needed. Improved emergency department care for older adults will require providers to address the influence of other factors on the patient's health. This article describes recent and ongoing efforts to enhance the quality of emergency care for older adults using alternative management approaches spanning the spectrum from prehospital care, through the emergency department, and into evolving inpatient or outpatient processes of care.
