International perspectives on emergency department crowding

Explaining variation in health information seeking behaviour - Insights from a multilingual survey

OBJECTIVE

How best to provide an increasingly diverse population with health information has become a major concern for health policy makers in Europe and beyond. Our study aims to investigate factors explaining variation in people's health information seeking behaviour. Our findings can be used to identify target groups for policy interventions that aim to provide health information efficiently.

METHODS

Cross-sectional, paper-based, multilingual survey of a random sample of enrolees of two statutory health insurers in Hamburg, Germany. Data were collected from September to December 2017. Multivariable logistic regression was used to examine sociodemographic and health-related individual characteristics and their associations with participants' choice of ten sources of health information.

FINDINGS

Participants' choice of information sources differed significantly across the following sociodemographic and health-related characteristics: age, gender, immigration status, education, employment status, marital status and general state of health. Immigrants and individuals with low educational attainment were most likely to use emergency departments as sources of health information.

CONCLUSION

Policy interventions aiming to manage the use of health information sources should focus on immigrants and individuals with low educational attainment. Providing multilingual, low-threshold counselling and information services could be an efficient way to reduce short-term costs of health information seeking behaviour to health insurers or other payers of care while improving patient empowerment.

Risk of Hospitalization Associated with Cardiovascular Medications in the Elderly Italian Population: A Nationwide Multicenter Study in Emergency Departments

Background: There is a significant gap in knowledge addressing cardiovascular (CV) medications safety in elderly. In this context, our purposes were to define clinical and pharmacological characteristics of outpatients’ adverse drug events (ADEs) related to CV medications leading to emergency department (ED) visits in the elderly Italian patients according to different age groups, and to evaluate the risk of hospitalization associated to ADEs in this population.

Methods: A multicentre, retrospective study was performed on reports of suspected ADEs collected between 2007–2018 in 94 EDs involved in the MEREAFaPS Study. Elderly patients who experienced one or more CV medications-related ADEs leading to ED visit were selected. Patients’ characteristics, suspected (ATC classes B and C) and concomitant drugs, and ADE description were collected. Elderly patients were stratified into three age groups (65–74, 75–84, and ≥85 years) and compared to adults (18–64 years). Logistic regression analyses were used to estimate the reporting odds ratios (RORs) with 95% confidence intervals (CIs) of ADE-related hospitalization adjusting for sex, presence of two or more suspected drugs, concomitant drugs, and one or more comorbidities.

Results: Among elderly, 16,926 reports of suspected ADE related to CV medications were collected, and 6,694 (39.5%) resulted in hospitalization. Patients were mostly female, Caucasians, and middle-old (75–84). 78.9% of patients were treated with only one suspected drug, and 71.9% and 47.1% reported concomitant medications and comorbidities, respectively. Compared to adults, risk of hospitalization was significantly higher for middle-old and oldest-old patients exposed to vitamin K antagonists (1.29 [1.09–1.52] and 1.56 [1.30–187]), direct thrombin inhibitors (3.41 [1.44–8.08] and 4.12 [1.67–10.17]), antiplatelets (1.51 [1.26–1.81] and 2.09 [1.71–2.57]), and beta-blockers (1.89 [1.38–2.59 and 2.31 [1.60–3.35]). Overall, a higher risk of hospitalization was observed for renin-angiotensin system inhibitors (1.32 [1.04–1.68], 1.65 [1.32–2.06], and 2.20 [1.70–2.85]), presence of two or more concomitant drugs, and concomitant conditions.

Conclusion: Our real-world findings underline relevant safety aspects of CV medications in the elderly Italian population. ED clinicians must always consider the higher risk of hospitalization related to the use of CV drugs in elderly, particularly in oldest-old ones, for antiarrhythmics, beta-blocking agents, renin-angiotensin system inhibitors, antiplatelets, and anticoagulants.

The Meaning of Boarding in a Swedish Accident & Emergency Department: A Qualitative Study on Patients' Experiences of Awaiting Admission

The number of in-hospital beds in Sweden has decreased during recent decades, resulting in the smallest number (2.2 available beds/1000 inhabitants) within the European Union. At the same time, the number of patients attending Accident and Emergency (A&E) departments has increased, resulting in overcrowding and boarding. The aim of this study was to explore the meaning of being subjected to boarding at an A&E department, as experienced by patients. A phenomenological-hermeneutic approach was chosen to interpret and understand the meaning of boarding at A&E. The study was carried out at a hospital in the south of Sweden. Seventeen participants with a mean age of 64 years (range: 35-86 years) were interviewed. The thematic structural analysis covers seven themes: Being in a state of uncertainty, Feeling abandoned, Fearing death, Enduring, Adjusting to the circumstances, Being a visitor in an unsafe place, and Acknowledging the staff, all illustrating that the participants were in a state of constant uncertainty and felt abandoned with no guidance or support from the clinicians. The conclusion is that the situation where patients are forced to wait in A&E, i.e., boarding, violates all conditions for professional ethics, presumably causing profound ethical stress in the healthcare professionals involved. Thus, boarding should be avoided.

Agreement between emergency physicians and radiologists for the diagnosis of deep venous thrombosis with compression ultrasound: a prospective study

INTRODUCTION

The time factor in diagnosis and management of a deep vein thrombosis of the lower extremities (LE DVT) is of increasing importance in the era of crowding of emergency departments (ED). Current techniques used to detect LE DVT include a two-point regional compression ultrasound (rCUS), yet assessments are usually performed only during office hours. Outside office hours ultrasonography is postponed and low molecular weight heparin (LMWH) prescribed.

OBJECTIVES

Primary outcome of the study was to assess the level of agreement in rCUS for LE DVT when performed by Dutch emergency physicians compared to rCUS by a radiologist. Secondary outcome was time to diagnosis.

METHOD

We performed a single-blind cohort study. All consecutive patients aged 18 years and older attending the ED with clinical suspicion of LE DVT were considered eligible for study enrolment. rCUS was ordered at the radiology department; subsequently, the bedside rCUS examination was also performed in the ED by the emergency physicians or ED residents.

RESULTS

A total of 138 patients were included, of whom 28 patients were diagnosed with DVT by a radiologist. Emergency physicians and radiologists showed comparable agreement [absolute agreement 94% (P < 0.001), Cohen's Kappa 0.87]. Emergency physicians decreased overall time to diagnosis by 01:04 h, ED residents showed comparable results. During out-of-office hours, time benefit was 16:39 h on weekdays and 18:40 h during weekends.

CONCLUSION

Emergency physicians show comparable agreement in diagnosing LE DVT using rCUS when compared to radiologists. Average time benefit is over an hour, thereby reducing unnecessary waiting and improving time to disposition. ED residents demonstrated similar results in both agreement and time-saving.

Injuries and frequent use of emergency department services: a systematic review

OBJECTIVE

To review all studies having examined the association between patients with physical injuries and frequent emergency department (ED) attendance or return visits.

DESIGN

Systematic review.

DATA SOURCE

Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and PsycINFO databases were searched up to and including July 2019.

ELIGIBILITY CRITERIA

English and French language publications reporting on frequent use of ED services (frequent attendance and return visits), evaluating injured patients and using regression analysis.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers screened the search results, and assessed methodological quality using the Joanna Briggs Institute tool for prevalence studies. Results were collated and summarised using a narrative synthesis. A sensitivity analysis was performed to evaluate the repercussions of removing a study that did not meet the quality criteria.

RESULTS

Of the 2184 studies yielded by this search, 1957 remained after the removal of duplicates. Seventy-eight studies underwent full-text screening leaving nine that met the eligibility criteria and were included in this study: five retrospective cohort studies; two prospective cohort studies; one cross-sectional study; and one case-control study. Different types of injuries were represented, including fractures, trauma and physical injuries related to falls, domestic violence or accidents. Sample sizes ranged from 200 to 1 259 809. Six studies included a geriatric population while three addressed a younger population. Of the four studies evaluating the relationship between injuries and frequent ED use, three reported an association. Additionally, of the five studies in which the dependent variable was return ED visits, three articles identified a positive association with injuries.

CONCLUSIONS

Physical injuries appear to be associated with frequent use of ED services (frequent ED attendance as well as return ED visits). Further research into factors including relevant youth-related covariates such as substance abuse and different types of traumas should be undertaken to bridge the gap in understanding this association.

Delayed flow is a risk to patient safety: A mixed method analysis of emergency department patient flow

INTRODUCTION

Increasing emergency department (ED) demand and crowding has heightened focus on the need for better understanding of patient flow.

AIM

This study aimed to identify input, throughput and output factors contributing to ED patient flow bottlenecks and extended ED length of stay (EDLOS).

METHOD

Concurrent nested mixed method study based on retrospective analysis of attendance data, patient flow observational data and a focus group in an Australian regional ED.

RESULTS

Analysis of 89 013 ED presentations identified increased EDLOS, particularly for patients requiring admission. Mapping of 382 patient journeys identified delays in time to triage assessment (0-39 mins) and extended waiting room stays (0-348 mins). High proportions of patients received care outside ED cubicles. Four qualitative themes emerged: coping under pressure, compromising care and safety, makeshift spaces, and makeshift roles.

CONCLUSION

Three key findings emerged: i) hidden waits such as extended triage-queuing occur during the input phase; ii) makeshift spaces are frequently used to assess and treat patients during times of crowding; and iii) access block has an adverse effect on output flow. Data suggests arrival numbers may not be a key predictor of EDLOS. This research contributes to our understanding of ED crowding and patient flow, informing service delivery and planning.

Evaluation of Process Improvement Interventions on Handoff Times between the Emergency Department and Observation Unit

BACKGROUND

Mitigating hospital crowding requires judicious use of inpatient resources, making Emergency Department Observation Units (EDOUs) an increasingly vital destination for patients that are not suitable for discharge. Maximizing the utility of the EDOU hinges on efficient patient transfers and safe provider communication, which may be accomplished with asynchronous handoff and an emphasis on pull-through operations.

OBJECTIVE

The purpose of this study was to assess the impact of an electronic, asynchronous handoff replacing verbal handoff on transfer times from the Emergency Department (ED) to the EDOU.

METHODS

A retrospective observational study was performed with patients transferred to the EDOU throughout several process improvement measures focused on asynchronous handoff. Multivariable linear regression analysis was used to determine the effect that these process improvements had on the time from EDOU bed assignment to patient transfer.

RESULTS

There were 14,996 EDOU stays during the 20-month period included in the analysis. Time from EDOU bed assignment to patient transfer decreased significantly with all three interventions studied. An auto-page to the clinicians notifying them of a ready bed reduced the mean time to transfer by 10.1 min (p < 0.0001), asynchronous nursing handoff reduced it by 3.57 min (p = 0.0299), and asynchronous clinician handoff reduced it by 14.67 min (p < 0.0001).

CONCLUSION

Introducing automatic pages regarding bed status and converting the handoff process from a verbal model to an asynchronous, electronic handoff were effective ways to reduce the time from bed assignment to transfer out of the ED for patients being sent to the EDOU.

Factors associated with the undertriage of patients with abdominal pain in an emergency room

INTRODUCTION

The triage process lasts for a very short time, which can result in over-triage and under-triage. Studies have explored factors related to under-triage among trauma patients. In Korea, the clinical characteristics and severity of cases of under-triaged patients have been investigated. However, there is limited research on the under-triage of patients experiencing abdominal pain. Therefore, this study aimed to determine the under-triage rate of emergency department (ED) patients with abdominal pain, as well as the factors associated with their under-triage.

METHODS

The participants of this retrospective cohort study were 3,030 adult patients at a single tertiary hospital in Korea, who were brought to the ED for abdominal pain as the chief complaint. Participants' general characteristics, pain-related information, and environmental information were obtained from their electronic medical records.

RESULTS

The under-triage rate of ED patients with abdominal pain was 31.0%. Factors related to the under-triage of these patients were sex, age, visit route, time from the onset of the pain to the visit, location of pain, and intensity of pain.

CONCLUSION

These findings provide a foundation for the understanding and mitigation of under-triage in EDs through the identification of factors associated with under-triage in patients with abdominal pain.

State Laws and Regulations Addressing Nurse-Initiated Protocols and Use of Nurse-Initiated Protocols in Emergency Departments: A Cross-Sectional Survey Study

INTRODUCTION

State regulations may impede the use of nurse-initiated protocols to begin life-saving treatments when patients arrive to the emergency department. In crowding and small-scale disaster events, this could translate to life and death practice differences. Nevertheless, research demonstrates nurses do utilize nurse-initiated protocols despite legal prohibitions. The purpose of this study was to explore the relationship of the state regulatory environment as expressed in nurse practice acts and interpretive statements prohibiting the use of nurse-initiated protocols with hospital use of nurse-initiated protocols in emergency departments.

METHODS

A cross-sectional approach was used with a nationwide survey. The independent variable categorized the location of the hospital in states that have a protocol prohibition. Outcomes included protocols for blood laboratory tests, X-rays, over-the-counter medication, and electrocardiograms. A second analysis was completed with New York State alone because this state has the strongest language prohibiting nurse-initiated protocols.

RESULTS

A total of 350 participants returned surveys from 48 states and the District of Columbia. A hospital was more likely to have policies supporting nurse-initiated protocols if they were not in a state with the scope of practice prohibitions. Four categories emerged such as advantages, approval, prohibition, and conditions under which the protocols can be used. Prohibitive language was associated with less protocol use for emergency care.

CONCLUSION

State scope of practice inconsistencies create misalignment with emergency nurse education and training, which may impede timely care and contribute to inequalities and inefficiencies in emergency care. In addition, prohibitive language places practicing nurses responding to emergencies in crowded work environments at risk.

Likelihood of admission to hospital from the emergency department is not universally associated with hospital bed occupancy at the time of admission

Background

The decision to admit into the hospital from the emergency department (ED) is considered to be important and challenging. The aim was to assess whether previously published results suggesting an association between hospital bed occupancy and likelihood of hospital admission from the ED can be reproduced in a different study population.

Methods

A retrospective cohort study of attendances at two Swedish EDs in 2015 was performed. Admission to hospital was assessed in relation to hospital bed occupancy together with other clinically relevant variables. Hospital bed occupancy was categorized and univariate and multivariate logistic regression were performed.

Results

In total 89,503 patient attendances were included in the final analysis. Of those, 29.1% resulted in admission within 24 h. The mean hospital bed occupancy by the hour of the two hospitals was 87.1% (SD 7.6). In both the univariate and multivariate analysis, odds ratio for admission within 24 h from the ED did not decrease significantly with an increasing hospital bed occupancy.

Conclusions

A negative association between admission to hospital and occupancy level, as reported elsewhere, was not replicated. This suggests that the previously shown association might not be universal but may vary across sites due to setting specific circumstances.

Length of Stay in the Emergency Department and Its Associated Factors at Jimma Medical Center, Southwest Ethiopia

Background

Prolonged emergency department stays can adversely affect patient outcomes leading to an increased length of hospital admission and higher mortality. Despite this fact, there are few data describing emergency department length of stay and associated factors in Ethiopia.

Objective

To assess length of stay in the emergency department and its associated factors among patients visited adult emergency department of Jimma Medical Center, Jimma town, southwest of Ethiopia.

Methods

Institution-based cross-sectional study was conducted from April 9, 2018 to May 11, 2018. Overall, 422 patients presented during study period were sequentially included in the study. A semi-structured questionnaire was used to collect data through interview, observation and medical record review. The collected data were cleaned, entered to Epi-data 3.1 and exported to SPSS version 21 for binary and multivariable logistic regression analysis. To identify factors associated with outcome variable, candidate variables were fitted to multivariable analysis, and those with P-values <0.05 were considered as significantly associated.

Results

More than one-third, 162 (38.4%), experienced prolonged length of stay in the emergency department. The odds of prolonged stay were higher among rural area residency (AOR, 3.0; CI, 1.279–7.042), evening presentation (AOR, 4.25; CI, 1.742–10.417), and night-time presentation (AOR, 14.93; CI, 4.22–52.63), and having at least one diagnostic investigation (AOR, 4.48; CI, 1.69–11.88). However, participants who did not experience shift changes of nurses during their stay (AOR, 0.003; CI, 0.001–0.010) had a less prolonged stay.

Conclusion

A significant proportion of patients experienced a prolonged stay at the emergency department. Age, rural residency, evening and night-time presentation, shift change and having a diagnostic investigation were predictors of prolonged stay. Thus, establishing time-targeted service for patients can reduce the length of stay.

Worth the wait: The impact of government funding on hospital emergency waiting times

In the absence of a price mechanism, emergency department waiting times act as a rationing device to equate demand for treatment with available supply. Sustained increases to demand stemming from population growth, aging populations, and rising comorbidities has caused waiting times internationally to rise. This has resulted in increased calls for higher funding from governments and commitments from both state and national governments to address excessive waiting times. This paper aims to determine the effectiveness of government funding for improving the median waiting times for treatment and the proportion of patients seen within clinically recommended waiting times. For this purpose, an econometric analysis was conducted on a panel of data on Victorian local health networks over the period 2015-2018. This is supplemented with a discussion of the alternative measures which governments might take to both address demand for emergency treatment, and also ensure that waiting time reductions can be maintained over the long-term.

The influence of personal communities in understanding avoidable emergency department attendance: qualitative study

BACKGROUND

Use of emergency department (ED) care globally seems to be increasing at a faster rate than population growth (Baker, House of Commons Library. Accident and Emergency Statistics, Demand, Performance, 2017). In the UK there has been a reported 16% rise in emergency admissions over the past 5 years. Estimates that between 11 and 40% of ED attendances are non-urgent, with 11% of patients being discharged from the ED without treatment (NHS Digital 2017), and a further 44% require no follow-up treatment (NHS Digital, Hospital Accident and Emergency Activity 2016-17, 2019) is cited as evidence that these patients did not require this level of care. The solution to not using the most appropriate point in the system has traditionally been seen as a knowledge problem, requiring, improved sign-posting and information to enable people to self-manage or use health care management for minor ailments. However research about help-seeking behaviour suggests that the problem may not be an informational one. A considerable literature points to help seeking as a social process influenced by a range of contingencies and contextual factors including the way in which lay people influence health care utilisation (Giebel et al. BMJ Open 9:1, 2019). Personal communities comprise a variety of active and significant social ties which have potential to influence individual capacity to seek help. Here we extend and unpack further influencing decisions about seeking formal health care with reference to how they are shaped and informed by and within personal social networks.

METHODS

We undertook a personal network mapping and qualitative interview-based study to look at, problematize and understand attendance for non-urgent problems. We used network analysis and methods to map and characterise the personal communities of people seeking help from ED for minor ailments and semi-structured interviews with 40 people attending a single ED and associated GP hub providing equivalent care. Interviews were built around an ego network mapping activity and a topic guide structured to explore attender's narratives about why they had visited the ED. This ego network activity uses a diagram consisting of three concentric circles (Fiori et al. J Gerontol B-Psychol 62: 322-30, 2007), representing closest social network members (in the centre) and those at further distance. Participants were initially presented with one of these diagrams and asked to write names of people or resources that had played a role in their attendance and the interviewer probed the interviewee to discuss the actions, input and value of the people and services that supported the visit to the ED.

RESULTS

We analysed number and type of network connections and undertook a thematic analysis to identify how imagined and actual network members and influences were implicated in ED attendance. The network maps created during the interviews were examined and a typology of networks was developed and used to distinguish different types of networks informed by our reading of the data, and a Network Typology Scoring Tool, a measure of frequency of contact and relationship type in networks.

CONCLUSIONS

Our study suggests that faced with acute minor illness or injury people's networks narrow: they do not (and perhaps cannot) mobilise their imagined care network because the resources or connections may not be there or are difficult to engage. In addition we identified important system drivers of behaviour, notably that these patients are often directed to the ED by 'professional influencers' including health services staff.

Longitudinal description and evaluation of an emergency department avoidance strategy for a youth mass gathering (Schoolies) in Australia

OBJECTIVE

ED avoidance strategies including In-Event Health Service (IEHS) processes during mass gathering events (MGEs), such as 'Schoolies week', may be important for EDs, ambulance services, the local population, and attendees. The aim of the present study was to provide a longitudinal description of emergency care requirements for young adults (16-18 years old); focussing on the impact of the Schoolies MGEs.

METHODS

This retrospective observational study included youth (16-18 years) presentations made (i) to local public EDs during Schoolies week in 2008-2014 and (ii) to local EDs over a 3-week period (pre, during, post-Schoolies week) and the IEHS in 2015 and 2016. Descriptive and inferential statistics were undertaken.

RESULTS

Youth presentations (n = 4256) were included. Presentation rates/1000 fluctuated over time (range 6.2-21.2). The IEHS provided care for 167 and 288 youth during 2015 and 2016 Schoolies week, respectively. Demographic factors (gender, age, region domiciled) and episode of care factors (time of presentation, mode of arrival, urgency, time to triage, time to be seen by a clinician and length of stay) between 2008 and 2016 varied by year. Toxicology (alcohol and other drugs), trauma, and mental health concerns were the most common diagnoses.

CONCLUSIONS

The IEHS, operational during Schoolies, appeared to reduce pressures on local EDs by offering rapid, targeted care for potentially vulnerable youth; decrease requirements for hospital transport and minimise impacts on care provision for the local community. Given increases in ED crowding and pressures on ambulance services, such care models may be worth considering for other types of MGEs and in other locations.

Self-referred walk-in patients in the emergency department - who and why? Consultation determinants in a multicenter study of respiratory patients in Berlin, Germany

BACKGROUND

Emergency department (ED) consultations are on the rise, and frequently consultations by non-urgent patients have been held accountable. Self-referred walk-in (SRW) consulters supposedly represent a predominantly less urgent patient population. The EMACROSS study aimed to explore consultation determinants and motives in SRW patients with respiratory symptoms.

METHODS

Multicenter survey of adult ED patients with respiratory complaints in eight emergency departments in central Berlin, Germany. Secondary hospital records data including diagnoses was additionally assessed. Characteristics of SRW and non-SRW patients were compared. Determinants of SRW consultation were evaluated by binary logistic regression. Consultation motives were analyzed descriptively. As a supplemental approach, network analysis (lasso-regularized mixed graphical model) was performed to explore connections between consultation determinants, consultation features and motives.

RESULTS

Between June 2017 and November 2018, n = 472 participants were included, the median age was 55 years (range 18-96), 53.2% of patients were male and n = 185 cases (39.2%) were SRW consulters. The SRW group showed lower proportions of potentially severe (pneumonia and respiratory failure, p < 0.001, χ2 test) and chronic pulmonary conditions. Determinants of SRW consultation identified by logistic regression were younger age (p < 0.001), tertiary education (p = 0.032), being a first-generation migrant (p = 0.002) or tourist (p = 0.008), having no regular primary care provider (p = 0.036) and no chronic pulmonary illness (p = 0.017). The area under the curve (AUC) for the model was 0.79. Personal distress and access problems in ambulatory care were stated most frequently as consultation motives in the SRW group; network analysis showed the scarcity of associations between demographic and medical SRW determinants and motives triggering the actual decision to consult.

CONCLUSIONS

As to "who" consults, this study identified demographic and medical predictors of SRW utilization. The said markers seem only remotely connected to "why" people decide for SRW visits. To alleviate ED crowding by addressing frequent SRW consultation motives, interventions focused on the ability for symptom self-assessment and at better-accessible alternative care seem sensible.

Indicators of home-based hospitalization model and strategies for its implementation: a systematic review of reviews

BACKGROUND

Home-based hospitalization (HBH) offers an alternative delivery model to hospital care. There has been a remarkable increase in pilot initiatives and deployment of this model to optimize services offered to a population with a variety of progressive and chronic diseases. Our objectives were to systematically summarize the indicators of HBH as well as the factors associated with the successful implementation and use of this model.

METHODS

We used a two-stage process. First, five databases were consulted, with no date delimitation. We included systematic reviews of quantitative, qualitative, and mixed studies published in English, French, Spanish, or Portuguese. We followed guidance from PRISMA and the Cochrane Collaboration. Second, we used the Nursing Care Performance Framework to categorize the indicators, a comprehensive grid of barriers and facilitators to map the factors affecting HBH implementation, and a thematic synthesis of the qualitative and quantitative findings.

RESULTS

Fifteen reviews were selected. We identified 26 indicators related to nursing care that are impacted by the use of HBH models and 13 factors related to their implementation. The most frequently documented indicators of HBH were cost of resources, problem and symptom management, comfort and quality of life, cognitive and psychosocial functional capacity, patient and caregiver satisfaction, hospital mortality, readmissions, and length of stay. Our review also highlighted new indicators, namely use of hospital beds, new emergency consultations, and use of healthcare services as indicators of resources of cost, and bowel complications, caregiver satisfaction, and survival time as indicators of change in the patient's condition. The main facilitators for HBH implementation were related to internal organizational factors (multidisciplinary collaboration and skill mix of professionals) whereas barriers were linked to the characteristics of the HBH, specifically eligibility criteria (complexity and social situation of the patient).

CONCLUSION

To the best of our knowledge, this is the first review that synthesizes both the types of indicators associated with HBH and the factors that influence its implementation. Considering both the processes and outcomes of HBH will help to identify strategies that could facilitate the implementation and evaluation of this innovative model of care delivery.

What role does the GP play for emergency department utilizers? A qualitative exploration of respiratory patients' perspectives in Berlin, Germany

BACKGROUND

While motives for emergency department (ED) self-referrals have been investigated in a number of studies, the relevance of general practitioner (GP) care for these patients has not been comprehensively evaluated. Respiratory symptoms constitute an important utilization trigger in both EDs and in primary care. In this qualitative study, we aimed to explore the role of GP care for patients visiting EDs as outpatients for respiratory complaints and the relevance of the relationship between patient and GP in the decision making process leading up to an ED visit.

METHODS

Qualitative descriptive study. Semi-structured, face-to-face interviews with a sample of 17 respiratory ED patients in Berlin, Germany. Interviews were recorded and transcribed verbatim. Qualitative content analysis was performed. The study was embedded into the EMACROSS (Emergency and Acute Care for Respiratory Diseases beyond Sectoral Separation) cohort of ED patients with respiratory symptoms, which is part of EMANet (Emergency and Acute Medicine Network for Health Care Research).

RESULTS

Three patterns of GP utilization could be differentiated: long-term regular consulters, sporadic consulters and patients without GP. In sporadic consulters and patients without GP, an ambivalent or even aversive view of GP care was prevalent, with lack of confidence in GPs' competence and a deficit in trust as seemingly relevant influencing factors. Regardless of utilization or relationship type, patients frequently made contact with a GP before visiting an ED.

CONCLUSIONS

With regard to respiratory symptoms, our qualitative data suggest a hypothesis of limited relevance of patients' primary care utilization pattern and GP-patient relationship for ED consultation decisions.

Prolonged Length of Stay in the Emergency Department and Increased Risk of In-Hospital Cardiac Arrest: A nationwide Population-Based Study in South Korea, 2016-2017

This study was to determine whether prolonged emergency department (ED) length of stay (LOS) is associated with increased risk of in-hospital cardiac arrest (IHCA). A retrospective cohort with a nationwide database of all adult patients who visited the EDs in South Korea between January 2016 and December 2017 was performed. A total of 18,217,034 patients visited an ED during the study period. The median ED LOS was 2.5 h. IHCA occurred in 9,180 patients (0.2%). IHCA was associated with longer ED LOS (4.2 vs. 2.5 h), and higher rates of intensive care unit (ICU) admission (58.6% vs. 4.7%) and in-hospital mortality (35.7% vs. 1.5%). The ED LOS correlated positively with the development of IHCA (Spearman ρ = 0.91; p < 0.01) and was an independent risk factor for IHCA (odds ratio (OR) 1.10; 95% confidence interval (CI), 1.10-1.10). The development of IHCA increased in a stepwise fashion across increasing quartiles of ED LOS, with ORs for the second, third, and fourth relative to the first being 3.35 (95% CI, 3.26-3.44), 3.974 (95% CI, 3.89-4.06), and 4.97 (95% CI, 4.89-5.05), respectively. ED LOS should be reduced to prevent adverse events in patients visiting the ED.

NEDOCS: is it really useful for detecting emergency department overcrowding today?

The Emergency Department (ED) overcrowding is an ongoing problem all over the world. The scoring systems are available for the detection of this problem. This study aims to test the applicability of the National Emergency Department Overcrowding Study (NEDOCS) scoring system, one of the scoring systems that evaluate the ED overcrowding.In this prospective observational study, the survey was applied on on-duty doctors, nurses, paramedics, intern doctors, and ward persons working in a University Adult Emergency Department and agreed to participate in the study, between certain hours during the day and the NEDOCS score was calculated simultaneously. The demographic characteristics of the on-duty staff, overcrowding of ED, and the number of the on-duty staff members were recorded in the questionnaires.During the study, 153 measurements were performed, and 3221 questionnaires were filled. The NEDOCS mean score was determined as 101.59 and the most reached result was "extremely busy but not overcrowded" (32%). The ED was rated mostly as "busy" (33.7%) by the on-duty staff. A significant difference was found between ED overcrowding and NEDOCS score. There is a significant difference between ED overcrowding and on-duty emergency nurse and intern doctor count.The NEDOCS score is not suitable for evaluating ED overcrowding. Accurate determination of the ED overcrowding is very important to avoid the negative consequences of the ED overcrowding. Increasing emergency nurse and intern doctor count will decrease ED overcrowding. Also, there is an urgent need to constitute local hospitals and also public health policies to satisfy the increasingly ED's presentations.

Characteristics and subgroups of frequent emergency department users in an academic hospital in Japan

Aim

Frequent emergency department (ED) users increase the burden on EDs. However, little is known about the characteristics and subgroups of frequent ED users in Japan.

Methods

We retrospectively analyzed data on patients who had visited the ED of an academic hospital in Japan between 2014 and 2015. We identified adult frequent ED users (four or more ED visits within 365 days prior to one’s last visit) and sampled adult non‐frequent ED users. We compared these groups to delineate the characteristics of frequent ED users and examined the association between frequent ED use and hospitalization rates. Additionally, to identify latent subgroups of frequent ED users, we undertook a cluster analysis.

Results

We identified 259 frequent ED users and 297 non‐frequent ED users from 9,546 patients who had visited the ED in 2015. Frequent ED users accounted for 8.2% of all ED visits. Frequent ED users tended to be older, have comorbidities, and be receiving public assistance compared to non‐frequent ED users. There was a significant association between frequent ED use and higher hospitalization rates, which was partially attributable to (older) age and comorbidities. In the cluster analysis, we identified four subgroups of frequent ED users: (i) older patients with malignant tumors and the highest hospitalization rates, (ii) patients with mental illnesses and the lowest hospitalization rates, (iii) patients who were at risk of cardiovascular diseases, (iv) others.

Conclusions

Frequent ED users tended to be older and have comorbidities. Four latent subgroups of frequent ED users were identified.

Interventions in overcrowding of emergency departments: an overview of systematic reviews

OBJECTIVE

To present an overview of systematic reviews on throughput interventions to solve the overcrowding of emergency departments.

METHODS

Electronic searches for reviews published between 2007 and 2018 were made on PubMed, Cochrane Library, EMBASE, Health Systems Evidence, CINAHL, SciELO, LILACS, Google Scholar and the CAPES periodicals portal. Data of the included studies was extracted into a pre-formatted sheet and their methodological quality was assessed using AMSTAR 2 tool. Eventually, 15 systematic reviews were included for the narrative synthesis.

RESULTS

The interventions were grouped into four categories: (1) strengthening of the triage service; (2) strengthening of the ED’s team; (3) creation of new care zones; (4) change in ED’s work processes. All studies observed positive effect on patient’s length of stay, expect for one, which had positive effect on other indicators. According to AMSTAR 2 criteria, eight revisions were considered of high or moderate methodological quality and seven, low or critically low quality. There was a clear improvement in the quality of the studies, with an improvement in focus and methodology after two decades of systematic studies on the subject.

CONCLUSIONS

Despite some limitations, the evidence presented on this overview can be considered the cutting edge of current scientific knowledge on the topic.

Prevalence of crowding, boarding and staffing levels in Swedish emergency departments - a National Cross Sectional Study

Background

Emergency Department (ED) crowding occurs when demand for care exceeds the available resources. Crowding has been associated with decreased quality of care and increased mortality, but the prevalence on a national level is unknown in most countries.

Method

We performed a national, cross-sectional study on staffing levels, staff workload, occupancy rate and patients waiting for an in-hospital bed (boarding) at five time points during 24 h in Swedish EDs.

Results

Complete data were collected from 37 (51% of all) EDs in Sweden. High occupancy rate indicated crowding at 12 hospitals (37.5%) at 31 out of 170 (18.2%) time points. Mean workload (measured on a scale from 1, no workload to 6, very high workload) was moderate at 2.65 (±1.25). Boarding was more prevalent in academic EDs than rural EDs (median 3 vs 0). There were an average of 2.6, 4.6 and 3.2 patients per registered nurse, enrolled nurse and physician, respectively.

Conclusion

ED crowding based on occupancy rate was prevalent on a national level in Sweden and comparable with international data. Staff workload, boarding and patient to staff ratios were generally lower than previously described.

The growing impact of older patients in the emergency department: a 5-year retrospective analysis in Brazil

BACKGROUND

The average age of the global population is rising at an increasing rate. There is a disproportional increase in Emergency Department (ED) visits by older people worldwide. In the Brazilian health system, complex and severely ill patients and those requiring specialized urgent procedures are referred to tertiary level care. As far as we know, no other study in Latin America has analyzed the impact of demographic changes in tertiary ED attendance.

AIM

To describe the sociodemographic characteristics and outcomes of tertiary Brazilian ED users.

METHODS

Design: Observational cross-sectional analytic study.

SETTING

Emergency Department, tertiary university hospital, São Paulo, Brazil.

PARTICIPANTS

patients aged 18 years or older attending a tertiary ED (2009-2013). The primary outcomes were hospitalization and mortality; the secondary outcome was ICU admission. Age was categorized as 'young adults' (18-39y), 'adults' (40-59y), 'young-older adults' (60-79y), and 'old-older adults' (80-109y). Other variables included sex, reason for attendance, time of ED visit, mode of presentation, type of hospitalization, main procedure, length of hospital stay (LOS) and length of ICU stay (ICU-LOS). We calculated descriptive statistics, built generalized linear mixed models for each outcome and estimated Odds Ratios (95% CI) for the independent categorical variables. The significance level was 5% with Bonferroni correction.

RESULTS

Older age-groups represented 26.6% of 333,028 ED visits, 40.7% of admissions, 42.7% of ICU admissions and 58% of all deaths. Old-older patients accounted for 5.1% of ED visits, 9.5% of admissions and 10.1% of ICU admissions. Hospitalization, ICU admission and mortality rates increased with older age in both sexes. LOS and ICU-LOS were similar across age-groups. The proportions of visits and admissions attributed to young adults decreased annually, while those of people aged 60 or over increased. The ORs for hospitalization, ICU admission and mortality associated with the old-older group were 3.49 (95% CI = 3.15-3.87), 1.27 (1.15-1.39) and 5.93 (5.29-6.66) respectively, with young adults as the reference.

CONCLUSIONS

In tertiary ED, age is an important risk factor for hospitalization and mortality, but not for ICU admission. Old-older people are at the greatest risk and demand further subgroup stratification.

Maximum emergency department overcrowding is correlated with occurrence of unexpected cardiac arrest

Background

Emergency department overcrowding negatively impacts critically ill patients and could lead to the occurrence of cardiac arrest. However, the association between emergency department crowding and the occurrence of in-hospital cardiac arrest has not been thoroughly investigated. This study aimed to evaluate the correlation between emergency department occupancy rates and the incidence of in-hospital cardiac arrest.

Methods

A single-center, observational, registry-based cohort study was performed including all consecutive adult, non-traumatic in-hospital cardiac arrest patients between January 2014 and June 2017. We used emergency department occupancy rates as a crowding index at the time of presentation of cardiac arrest and at the time of maximum crowding, and the average crowding rate for the duration of emergency department stay for each patient. To calculate incidence rate, we divided the number of arrest cases for each emergency department occupancy period by accumulated time. The primary outcome is the association between the incidence of in-hospital cardiac arrest and emergency department occupancy rates.

Results

During the study period, 629 adult, non-traumatic cardiac arrest patients were enrolled in our registry. Among these, 187 patients experienced in-hospital cardiac arrest. Overall survival discharge rate was 24.6%, and 20.3% of patients showed favorable neurologic outcomes at discharge. Emergency department occupancy rates were positively correlated with in-hospital cardiac arrest occurrence. Moreover, maximum emergency department occupancy in the critical zone had the strongest positive correlation with in-hospital cardiac arrest occurrence (Spearman rank correlation ρ = 1.0, P < .01). Meanwhile, occupancy rates were not associated with the ED mortality.

Conclusion

Maximum emergency department occupancy was strongly associated with in-hospital cardiac arrest occurrence. Adequate monitoring and managing the maximum occupancy rate would be important to reduce unexpected cardiac arrest.

Adjacent Primary Care May Reduce Less Urgent Pediatric Emergency Department Visits

Aims: Pediatric emergency department (ED) overcrowding is a challenge. This study was designed to evaluate if a hospital-integrated primary care unit (HPCU) reduces less urgent visits at a pediatric ED. Methods: This retrospective cross-sectional study was carried out at a university hospital in Sweden, where the HPCU, open outside office hours, had been integrated next to the ED. Children seeking ED care during 4-week high- and low-load study periods before (2012) and after (2015) implementation of the HPCU were included. Information on patient characteristics, ED management, and length of ED stay was obtained from hospital data registers. Results: In total, 3216 and 3074 ED patient visits were recorded in 2012 and 2015, respectively. During opening hours of the HPCU, the proportions of pediatric ED visits (28% lower; P < .001), visits in the lowest triage group (36% lower; P < .001), patients presenting with fever (P = .001) or ear pain (P < .001), and nonadmitted ED patients (P = .033), were significantly lower in 2015 than in 2012, whereas the proportion of infants ≤3 months was higher in 2015 (P < .001). Conclusions: By enabling adjacent management of less urgent pediatric patients at adequate lower levels of medical care, implementation of a HPCU outside office hours may contribute to fewer and more appropriate pediatric ED visits.

A Front-end Redesign With Implementation of a Novel "Intake" System to Improve Patient Flow in a Pediatric Emergency Department

Introduction

Children's Hospital Colorado is an academic, tertiary-care Level 1 Trauma Center with an emergency department (ED) that treats >70,000 patients/year. Patient volumes continue to increase, leading to worsening wait times and left-without-being-seen (LWBS) rates. In 2015, the ED's median door-to-provider time was 49 minutes [interquartile range (IQR) = 26-90], with a 3.2% LWBS rate. ED leadership, staff, and providers aimed to improve patient flow with specific goals to (1) decrease door-to-provider times to a median of <30 minutes and (2) decrease annual LWBS rate to <1%.

Methods

An inter-professional team utilized quality improvement and Lean methodology to study, redesign, and implement significant changes to ED front-end processes. Key process elements included (1) new Flow Nurse/EMT roles, (2) elimination of traditional registration and triage processes, (3) immediate "quick registration" and nurse assessment upon walk-in, (4) direct-bedding of patients, and (5) a novel "Intake" system staffed by a pediatric emergency medicine physician.

Results

In the 12 months following full implementation of the new front-end system, the median door-to-provider time decreased 49% to 25 minutes (IQR = 13-50), and the LWBS rate decreased from 3.2% to 1.4% (a 56% relative decrease). Additionally, the percentage of patients seen within 30 minutes of arrival increased, overall ED length-of-stay decreased, patient satisfaction improved, and no worsening of the unexpected 72-hour return rate occurred.

Conclusions

Using quality improvement and Lean methodology, an inter-professional team decreased door-to-provider times and LWBS rates in a large pediatric ED by redesigning its front-end processes and implementing a novel pediatric emergency medicine-led Intake system.

Updated framework on quality and safety in emergency medicine

OBJECTIVES

Quality and safety of emergency care is critical. Patients rely on emergency medicine (EM) for accessible, timely and high-quality care in addition to providing a 'safety-net' function. Demand is increasing, creating resource challenges in all settings. Where EM is well established, this is recognised through the implementation of quality standards and staff training for patient safety. In settings where EM is developing, immense system and patient pressures exist, thereby necessitating the availability of tiered standards appropriate to the local context.

METHODS

The original quality framework arose from expert consensus at the International Federation of Emergency Medicine (IFEM) Symposium for Quality and Safety in Emergency Care (UK, 2011). The IFEM Quality and Safety Special Interest Group members have subsequently refined it to achieve a consensus in 2018.

RESULTS

Patients should expect EDs to provide effective acute care. To do this, trained emergency personnel should make patient-centred, timely and expert decisions to provide care, supported by systems, processes, diagnostics, appropriate equipment and facilities. Enablers to high-quality care include appropriate staff, access to care (including financial), coordinated emergency care through the whole patient journey and monitoring of outcomes. Crowding directly impacts on patient quality of care, morbidity and mortality. Quality indicators should be pragmatic, measurable and prioritised as components of an improvement strategy which should be developed, tailored and implemented in each setting.

CONCLUSION

EDs globally have a remit to deliver the best care possible. IFEM has defined and updated an international consensus framework for quality and safety.

Characteristics of frequent adult emergency department users: A Korean tertiary hospital observational study

Emergency department (ED) crowding is a public health burden that impedes the provision of high-quality emergency care and is related to poor outcomes. Frequent ED visits are known to contribute to ED crowding. This study aimed to identify frequent ED users' characteristics and risk factors related to frequent ED visits.A retrospective observational study was conducted using ED-based data derived from adult patients at a university hospital. The main exposure variable was frequent ED visits, which were defined as ≥4 visits within 12 months (January 1-December 31, 2018). Characteristics and risk factors for frequent ED users were evaluated using stepwise regression analysis.Within the study period, there were 36,932 ED visits involving 29,759 patients. Of these, 3031 (8.2%) visits were from 556 (1.9%) patients classified as frequent ED users. The independent risk factors for frequent ED visits were older patients (≥65 years); the winter season; daytime discharge from ED; patients with medical aid insurance; and patients designated as high acuity at their first visit. Patients with a malignant neoplasm, mental health disorder, alcohol-related liver disease, chronic kidney disease, or chronic obstructive pulmonary disease were associated with more frequent ED visits.Frequent ED users comprised a significant proportion of total ED visits. Frequent ED users were more likely than occasional ED users to be in poorer health, older, or have a chronic disease or a mental health disorder.

Asylum Seekers and Swiss Nationals with Low-Acuity Complaints: Disparities in the Perceived level of Urgency, Health Literacy and Ability to Communicate-A Cross-Sectional Survey at a Tertiary Emergency Department

Background: Emergency departments (EDs) are being increasingly used for low-acuity conditions and as primary care providers. Research indicates that patients with the status of asylum seeker (AS) may be seeking care in EDs at higher levels than nationals. The aim of this study was to identify disparities in the use of emergency care between AS and Swiss nationals (SN) with non-urgent complaints. Methods: Data were obtained from a survey in the period 01/12/2016–31/07/2017 of walk-in low-acuity patients attending the ED of the University Hospital Bern (Switzerland). AS and a gender, age-matched control group of SN of ≥16 years of age were included. Sociodemographic and survey data comprised information about health-seeking behavior in the home and reception country, knowledge of health care systems (HCSs), barriers to care and perceived acuity of the visit. Furthermore, attending physicians assessed the level of urgency of each case. Results: Among AS patients, 30.2% reported that they had no knowledge of the Swiss HCS. In total, 14.2% considered that their medical needs were non-urgent. On the other hand, 43.4% of the attending physicians in the ER considered that the medical needs were non-urgent. This contrast was less pronounced in SN patients. The majority of AS (63.2%) and SN (67.6%) patients sought care from the ED without first contacting a GP. In 53.8% of cases, an interpreter was needed during the ED consultation. Conclusions: Several factors associated with health-seeking behavior in the ED differed between AS and SN patients. Measures to increase health literacy, provision of easily accessible primary care services and intercultural-trained staff could improve quality of care and reduce the usage of EDs as primary care providers.

Multiple criteria decision analysis approach to consider therapeutic innovations in the emergency department: The methoxyflurane organizational impact in acute trauma pain

BACKGROUND

Acute trauma pain is poorly managed in the emergency department (ED). The reasons are partly organizational: ED crowding and rare trauma care pathways contribute to oligoanalgesia. Anticipating the organizational impact of an innovative care procedure might facilitate the decision-making process and help to optimize pain management.

METHODS

We used a multiple criteria decision analysis (MCDA) approach to consider the organizational impact of methoxyflurane (self-administered) in the ED, introduced alone or supported by a trauma care pathway. A MCDA experiment was designed for this specific context, 8 experts in emergency trauma care pathways (leading physicians and pharmacists working in French urban tertiary hospitals) were recruited. The study involved four steps: (i) Selection of organizational criteria for evaluating the innovation's impact; (ii) assessment of the relative weight of each criterion; (iii) choice of appropriate scenarios for exploring the organizational impact of MEOX under various contexts; and (iv) software-assisted simulation based on pairwise comparisons of the scenarios. The final outcome measure was the expected overall organizational impact of methoxyflurane on a 0-to-100 scale (score >50: positive impact).

RESULTS

Nine organizational criteria were selected. "Mean length of stay in the ED" was the most weighted. Methoxyflurane alone obtained 59 as a total score, with a putative positive impact for eight criteria, and a neutral effect on one. When a trauma care pathway was introduced concomitantly, the impact of methoxyflurane was greater overall (score: 75) and for each individual criterion.

CONCLUSIONS

Our model highlighted the putative positive organizational impact of methoxyflurane in the ED-particularly when supported by a trauma care pathway-and the relevance of expert consensus in this particular pharmacoeconomic context. The MCDA approach could be extended to other research fields and healthcare challenges in emergency medicine.

Liu S, A. Camargo C, Aburawi E, Moeckel M, Slagman A, Christ M, Singer A, Tazarourte K, Rathlev NK, A. Grossman S, Bellou A. Association between boarding in the emergency department and in-hospital mortality: A systematic review

IMPORTANCE

Boarding in the emergency department (ED) is a critical indicator of quality of care for hospitals. It is defined as the time between the admission decision and departure from the ED. As a result of boarding, patients stay in the ED until inpatient beds are available; moreover, boarding is associated with various adverse events.

STUDY OBJECTIVE

The objective of our systematic review was to determine whether ED boarding (EDB) time is associated with in-hospital mortality (IHM).

METHODS

A systematic search was conducted in academic databases to identify relevant studies. Medline, PubMed, Scopus, Embase, Cochrane, Web of Science, Cochrane, CINAHL and PsychInfo were searched. We included all peer-reviewed published studies from all previous years until November 2018. Studies performed in the ED and focused on the association between EDB and IHM as the primary objective were included. Extracted data included study characteristics, prognostic factors, outcomes, and IHM. A search update in PubMed was performed in May 2019 to ensure the inclusion of recent studies before publishing.

RESULTS

From the initial 4,321 references found through the systematic search, the manual screening of reference lists and the updated search in PubMed, a total of 12 studies were identified as eligible for a descriptive analysis. Overall, six studies found an association between EDB and IHM, while five studies showed no association. The last remaining study included both ICU and non-ICU subgroups and showed conflicting results, with a positive association for non-ICU patients but no association for ICU patients. Overall, a tendency toward an association between EDB and IHM using the pool random effect was observed.

CONCLUSION

Our systematic review did not find a strong evidence for the association between ED boarding and IHM but there is a tendency toward this association. Further well-controlled, international multicenter studies are needed to demonstrate whether this association exists and whether there is a specific EDB time cut-off that results in increased IHM.

[Even low-acuity patients prefer hospital-based emergency care : A survey of non-urgent patients in an emergency department with unique regional position]

BACKGROUND

Besides increasing numbers of cases in German emergency departments (ED), the spectrum of attending patients is also changing. Patients with acute illnesses tend to prefer EDs to ambulatory care as primary contact point. This study examines the motives for use and use behavior of low-urgent ED-patients.

METHODS

Anonymous patient survey in the ED of Wolfsburg Hospital between 12/2015 and 03/2016 with descriptive analysis. All patients with low urgency (Manchester-Triage-System (MTS), levels blue and green) were eligible.

RESULTS

81.5% of respondents (729 evaluable out of 7000 questionnaires distributed) attended the ED between 8:00 a. m. and 5:00 p. m., 70.1 % of them were walk-in patients. The motive most frequently cited was that they would receive better care in the ED (48.3 %). Contrary to acuity assessment, 67.8 % of respondents considered themselves a medium to life-threatening emergency. As alternative option, 49.2 % would choose a nearby clinic in the region for their complaints.

CONCLUSION

Self-assessed urgency differs with acuity assessment according to MTS. Patients who fear an acute threat to their health do not use services provided in the ambulatory sector such as the emergency practice of the Association of Statutory Health Insurance Physicians in the immediate proximity sufficiently. Previous approaches for patient navigation do not seem to be successful in this setting. Strengthening of EDs as a single 24/7 access point for emergency care with simultaneous abolition of parallel care structures should be discussed.

Adjusting Daily Inpatient Bed Allocation to Smooth Emergency Department Occupancy Variation

Study Objective: Overcrowding in emergency departments (ED) is an increasingly common problem in Taiwanese hospitals, and strategies to improve efficiency are in demand. We propose a bed resource allocation strategy to overcome the overcrowding problem. Method: We investigated ED occupancy using discrete-event simulation and evaluated the effects of suppressing day-to-day variations in ED occupancy by adjusting the number of empty beds per day. Administrative data recorded at the ED of Taichung Veterans General Hospital (TCVGH) in Taiwan with 1500 beds and an annual ED volume of 66,000 visits were analyzed. Key indices of ED quality in the analysis were the length of stay and the time in waiting for outward transfers to in-patient beds. The model is able to analyze and compare several scenarios for finding a feasible allocation strategy. Results: We compared several scenarios, and the results showed that by reducing the allocated beds for the ED by 20% on weekdays, the variance of daily ED occupancy was reduced by 36.25% (i.e., the percentage of reduction in standard deviation). Conclusions: This new allocation strategy was able to both reduce the average ED occupancy and maintain the ED quality indices.

Online symptom checker diagnostic and triage accuracy for HIV and hepatitis C

We sought to address the prior limitations of symptom checker accuracy by analysing the diagnostic and triage feasibility of online symptom checkers using a consecutive series of real-life emergency department (ED) patient encounters, and addressing a complex patient population – those with hepatitis C or HIV. We aimed to study the diagnostic and triage accuracy of these symptom checkers in relation to an emergency room physician-determined diagnosis. An ED retrospective analysis was performed on 8363 consecutive adult patients. Eligible patients included: 90 HIV, 67 hepatitis C, 11 both HIV and hepatitis C. Five online symptom checkers were utilised for diagnosis (Mayo Clinic, WebMD, Symptomate, Symcat, Isabel), three with triage capabilities. Symptom checker output was compared with ED physician-determined diagnosis data in regards to diagnostic accuracy and differential diagnosis listing, along with triage advice. All symptom checkers, whether for combined HIV and hepatitis C, HIV alone or hepatitis C alone had poor diagnostic accuracy in regards to Top1 (<20%), Top3 (<35%), Top10 (<40%), Listed at All (<45%). Significant variations existed for each individual symptom checker, as some appeared more accurate for listing the diagnosis in the top of the differential, vs. others more apt to list the diagnosis at all. In regards to ED triage data, a significantly higher percentage of hepatitis C patients (59.7%; 40/67) were found to have an initial diagnosis with emergent criteria than HIV patients (35.6%; 32/90). Symptom checker diagnostic capabilities are quite inferior to physician diagnostic capabilities. Complex patients such as those with HIV or hepatitis C may carry a more specific differential diagnosis, warranting symptom checkers to have diagnostic algorithms accounting for such complexity. Symptom checkers carry the potential for real-time epidemiologic monitoring of patient symptoms, as symptom entries and subsequent symptom checker diagnosis could allow health officials a means to track illnesses in specific patient populations and geographic regions. In order to do this, accurate and reliable symptom checkers are warranted.

Why are there long waits at English emergency departments?

A core performance target for the English National Health Service (NHS) concerns waiting times at Emergency Departments (EDs), with the aim of minimising long waits. We investigate the drivers of long waits. We analyse weekly data for all major EDs in England from April 2011 to March 2016. A Poisson model with ED fixed effects is used to explore the impact on long (> 4 h) waits of variations in demand (population need and patient case-mix) and supply (emergency physicians, introduction of a Minor Injury Unit (MIU), inpatient bed occupancy, delayed discharges and long-term care). We assess overall ED waits and waits on a trolley (gurney) before admission. We also investigate variation in performance among EDs. The rate of long overall waits is higher in EDs serving older patients (4.2%), where a higher proportion of attendees leave without being treated (15.1%), in EDs with a higher death rate (3.3%) and in those located in hospitals with greater bed occupancy (1.5%). These factors are also significantly associated with higher rates of long trolley waits. The introduction of a co-located MIU is significantly and positively associated with long overall waits, but not with trolley waits. There is substantial variation in waits among EDs that cannot be explained by observed demand and supply characteristics. The drivers of long waits are only partially understood but addressing them is likely to require a multi-faceted approach. EDs with high rates of unexplained long waits would repay further investigation to ascertain how they might improve.

End-of-Life Admission to the Emergency Department: Experience of Mexico's National Cancer Institute of a Developing Country

BACKGROUND

Admission to the emergency department (ED) of patients with advanced or end-of-life (EoL) cancer saturates the services that provide active medical attention to the complications of anticancer therapy, and the lack of specific protocol limits proper handling.

OBJECTIVE

The aim of this study was to describe the characteristics of patients with advanced cancer admitted to the ED at the EoL in a comprehensive cancer center in Mexico.

PATIENTS AND METHODS

We conducted a retrospective analysis of patients admitted to ED of the National Cancer Institute of Mexico City, with 3 or less days before they died, between January 2011 and December 2018. The data collected included clinical and demographic characteristics, reason for admission to the ED, number of admissions to ED in the last month of life, and cancer treatment received.

RESULTS

A total of 426 patients were included; 60.8% were female with a median age of 60 years; 71.6% patients were receiving some kind of disease-modifying treatment, although the oncologist had considered they could die within 6 months, and 16 of them were receiving concomitant PC. 8.9% of these patients had been admitted 3 or more times to the ED in the last month. The principal reasons for admission to ED were dyspnea, uncontrolled pain, 12 patients were admitted in active death and 94 died within hours of admission to ED.

CONCLUSIONS

Palliative care approach in oncological patients admitted to ED is important to avoid unnecesary suffering at the EoL.

Emergency Medicine Resident-Driven Point of Care Ultrasound for Suspected Shoulder Dislocation

OBJECTIVE

To determine the impact of implementing a musculoskeletal in-service educational intervention for emergency medicine (EM) residents on the use of point-of-care ultrasound (POCUS) to diagnose and manage shoulder dislocations in the emergency department (ED).

METHODS

This study was conducted in the ED of an academic teaching hospital in Miami, Florida. It consisted of a short in-service educational intervention on how to perform and interpret POCUS, followed by an open, prospective convenience sample study in patients with clinical suspicion of shoulder dislocation. Twenty EM residents, with no prior shoulder scanning training, participated in the study. In all of the cases, the findings of the shoulder US were compared with radiographs, which were considered the reference standard. EM residents enrolled patients, and obtained and interpreted the shoulder US images.

RESULTS

Seventy-eight patients were evaluated to rule out shoulder dislocation and/or fracture. Diagnosis of the dislocated shoulder was made in 55 of 78 patients, 53 of whom had anterior dislocations. Resident-driven POCUS had a sensitivity and specificity of 100% to diagnose and rule out, respectively, shoulder dislocations and relocations. There were no differences in the number of dislocations diagnosed and relocated by early and advanced EM residents. Results from a POCUS were available 22 ± 2.8 minutes sooner than x-ray for initial diagnosis and 27 ± 2.9 minutes (P < 0.0001) sooner than x-ray for assessment of reduction.

CONCLUSIONS

EM resident physicians, with no previous training in shoulder US imaging, exposed to a brief in-service musculoskeletal education intervention, were able to diagnose shoulder dislocations via POCUS with high sensitivity and specificity. Shoulder US for dislocation should be a core component in EM training.

Admission Decisions Made by Emergency Physicians Can Reduce the Emergency Department Length of Stay for Medical Patients

Background

Emergency department (ED) overcrowding is a worldwide problem that poses a threat to patient safety by causing treatment delays and increasing mortality. Consultations are common and important in the emergency medicine profession and are associated with longer ED length of stay (LOS). The purpose of this study was to evaluate the impact of admission decisions by emergency physicians without consultations on the ED LOS and other quality indicators.

Methods

The study was a retrospective observational study comparing the ED LOS of patients admitted to the internal medicine (IM) department before and after the policy change regarding admission decisions that was implemented in October 2016. During and after the policy change, emergency physicians decided how to arrange for and treat medical patients by processing their admission and providing follow-up care without consultations. The ED LOS and other indicators of patients admitted to the IM department were compared between the study period (January to June 2017) and the control period (January to June 2016).

Results

The median ED LOS of patients admitted to the IM department decreased from 673 (IQR: 347-1,369) minutes in the control period to 237 (IQR: 166-364) minutes in the study period. There were no significant differences in the interdepartmental transfer rate or in-hospital mortality between the two periods.

Conclusions

The admission decisions regarding medical patients made by emergency physicians without specialty consultations reduced the ED LOS without a significant negative effect on mortality or hospital LOS.

Reducing overcrowding in an emergency department: a pilot study

OBJECTIVE

Exploring the use of forecasting models and simulation tools to estimate demand and reduce the waiting time of patients in Emergency Departments (EDs).

METHODS

The analysis was based on data collected in May 2013 in the ED of Recanto das Emas, Federal District, Brasil, which uses a Manchester Triage System. A total of 100 consecutive patients were included: 70 yellow (70%) and 30 green (30%). Flow patterns, observed waiting time, and inter-arrival times of patients were collected. Process maps, demand, and capacity data were used to build a simulation, which was calibrated against the observed flow times. What-if analysis was conducted to reduce waiting times.

RESULTS

Green and yellow patient arrival-time patterns were similar, but inter-arrival times were 5 and 38 minutes, respectively. Wait-time was 14 minutes for yellow patients, and 4 hours for green patients. The physician staff comprised four doctors per shift. A simulation predicted that allocating one more doctor per shift would reduce wait-time to 2.5 hours for green patients, with a small impact in yellow patients' wait-time. Maintaining four doctors and allocating one doctor exclusively for green patients would reduce the waiting time to 1.5 hours for green patients and increase it in 15 minutes for yellow patients. The best simulation scenario employed five doctors per shift, with two doctors exclusively for green patients.

CONCLUSION

Waiting times can be reduced by balancing the allocation of doctors to green and yellow patients and matching the availability of doctors to forecasted demand patterns. Simulations of EDs' can be used to generate and test solutions to decrease overcrowding.

Comparing Expert and Non-Expert Assessment of Patients Presenting with Neurological Symptoms to the Emergency Department: A Retrospective Observational Study

OBJECTIVE

Referrals to neurology in emergency departments (ED) are continuously increasing, currently representing 15% of all admissions. Existing triage systems were developed for general medical populations and have not been validated for patients with neurological symptoms.

METHODS

To characterize neurological emergencies, we first retrospectively analyzed symptoms, service times and resources of the cohort of neurological referrals to a German interdisciplinary ED (IED) during 2017 according to urgency determined by final IED diagnosis. In a second step, we performed a retrospective assignment of consecutive patients presenting in April 2017 according to internal guidelines as either acute (requiring diagnostic/therapeutic procedures within 24 hrs) or non-acute neurological conditions as well as a retrospective classification according to the Emergency Severity Index (ESI). Both assessments were compared with the urgency according to the final ER diagnosis.

RESULTS

In a 12-month period, 36.4% of 5340 patients were rated as having an urgent neurological condition; this correlated with age, door-to-doctor time, imaging resource use and admission (p < 0.001, respectively). In a subset of 275 patients, 59% were retrospectively triaged as acute according to neurological expertise and 48% according to ESI categories 1 and 2. Neurological triage identified urgency with a significantly higher sensitivity (94.8, p < 0.01) but showed a significantly lower specificity (55.1, p < 0.05) when compared to ESI (80.5 and 65.2, respectively).

CONCLUSION

The ESI may not take specific aspects of neurological emergency (eg, time-sensitivity) sufficiently into account. Refinements of existing systems or supplementation with dedicated neurological triage tools based on neurological expertise and experience may improve the triage of patients with neurological symptoms.

Ambulatory care-sensitive emergency department cases: a mixed methods approach to systemize and analyze cases in Germany

BACKGROUND

Internationally, emergency departments (ED) are treating increasing numbers of patients with conditions that could have been managed appropriately in ambulatory care (AC) settings. The aim of our study was to develop the first consensus-based list of AC-sensitive conditions commonly seen in German EDs and explore predictors of these visits.

METHODS

Our study used a Delphi survey of 30 physicians to compile a list of conditions they agreed were amenable to AC treatment. The group identified reasons why patients visit EDs instead of AC. We used the results to inform spatial regression models analysing the association of patient characteristics and attributes of AC with AC-sensitive ED visits based on 2015 district-level data.

RESULTS

Our study provides a list of AC-sensitive conditions based on the German ED context. Results suggest that, up to the age of 70 years, the older the patients, the less likely they seek EDs for these conditions. Results of our regression analyses suggest that AC-sensitive ED rates were significantly higher in districts with lower physician density. Patients' urgency perception and preferences were identified as main drivers of AC-sensitive ED visits.

CONCLUSION

Future policy measures should aim to help guide patients through the healthcare system so that they receive the best care in place that is most appropriate in terms of quality, safety and continuity of care. A list of AC-sensitive ED conditions can be used as a monitoring instrument and for further analyses of routine data to inform policy makers seeking to improve resource use and allocation.

Do Emergency Nurses Spend Enough Time on Nursing Activities? The Relationship Between Actual and Expected Patient Care Nursing Time

Background

The overcrowded environments of emergency departments (EDs) lead to increased clinical workloads for nurses and infl uences the quality of patient care. This study aimed to evaluate whether the quality of patient care meets the expectations of emergency nurses in Taiwan by measuring the amount of time nurses spend on patient care activities.

Methods

The direct observation study was conducted in one suburban academic hospital with approximately 80,000 annual ED visits. This study observed emergency nurses and the time they spent on their nursing activities. The directly measured times and nurse expected patient care nursing times were compared.

Results

For all 88 types of nursing activities recorded, each measured nursing time was less than the expected nursing time. On average, the measured nursing time was 82% less than the expected nursing time (2.0 ± 0.3 minutes vs. 11.6 ± 1.5 minutes, p < 0.01). Among the 88 types of nursing activities recorded, the average measured time spent on 76 types (86%) was less than 3 minutes. The nursing activity on which the longest time was spent was cerebrospinal fl uid study nursing (7 minutes). The most frequent nursing activity was documentation.

Conclusion

The nursing time spent on patient-care activities in EDs was much less than the nurses expected. The results may provide a basis for nursing quality measurements and manpower calculations for EDs.

Convenient primary care and emergency hospital utilisation

Participation and utilisation decisions lie at the heart of many public policy questions. I contribute new evidence by using hospital records to examine how access to primary care services affects utilisation of hospital Emergency Departments in England. Using a natural experiment in the roll out of services, I first show that access to primary care reduces Emergency Department visits. Additional strategies then allow me to separate descriptively four aspects of primary care access: proximity, opening hours, need to make an appointment, and eligibility. Convenience-oriented services divert three times as many patients from emergency visits, largely because patients can attend without appointments.
