Can Team Triage Improve Patient Flow in the Emergency Department? A Systematic Review and Meta-Analysis

Randomized controlled open-label trial to evaluate prioritization software for the secondary triage of patients in the pediatric emergency department

BACKGROUND

The continual increase in patient attendance at the emergency department (ED) is a worldwide health issue. The aim of this study was to determine whether the use of a secondary prioritization software reduces the patients' median length of stay (LOS) in the pediatric ED.

METHODS

A randomized, controlled, open-label trial was conducted over a 30-day period between March 15th and April 23rd 2021 at Lille University Hospital. Work days were randomized to use the patient prioritization software or the pediatric ED's standard dashboard. All time intervals between admission and discharge were recorded prospectively by a physician not involved in patient care during the study period. The study's primary endpoint was the LOS in the pediatric ED, which was expected to be 15 min shorter in the intervention group than in the control group. The secondary endpoints were specific time intervals during the stay in the pediatric ED and levels of staff satisfaction.

RESULTS

1599 patients were included: 798 in the intervention group and 801 in the control group. The median [interquartile range] LOS was 172 min [113-255] in the intervention group and 167 min [108-254) in the control group (p = 0.46). In the intervention group, the time interval between admission to the first medical evaluation for high-priority patients and the time interval between the senior physician's final evaluation and patient discharge were shorter (p < 0.01). The median satisfaction score was 68 [55-80] (average).

CONCLUSION

The patients' total LOS was not significantly shorter on days of intervention. However, use of the electronic patient prioritization tool was associated with significant decreases in some important time intervals during care in the pediatric ED.

Patient flow in emergency departments: a comprehensive umbrella review of solutions and challenges across the health system

BACKGROUND

Globally, emergency departments (EDs) are overcrowded and unable to meet an ever-increasing demand for care. The aim of this study is to comprehensively review and synthesise literature on potential solutions and challenges throughout the entire health system, focusing on ED patient flow.

METHODS

An umbrella review was conducted to comprehensively summarise and synthesise the available evidence from multiple research syntheses. A comprehensive search strategy was employed in four databases alongside government or organisational websites in March 2023. Gray literature and reports were also searched. Quality was assessed using the JBI critical appraisal checklist for systematic reviews and research syntheses. We summarised and classified findings using qualitative synthesis, the Population-Capacity-Process (PCP) model, and the input/throughput/output (I/T/O) model of ED patient flow and synthesised intervention outcomes based on the Quadruple Aim framework.

RESULTS

The search strategy yielded 1263 articles, of which 39 were included in the umbrella review. Patient flow interventions were categorised into human factors, management-organisation interventions, and infrastructure and mapped to the relevant component of the patient journey from pre-ED to post-ED interventions. Most interventions had mixed or quadruple nonsignificant outcomes. The majority of interventions for enhancing ED patient flow were primarily related to the 'within-ED' phase of the patient journey. Fewer interventions were identified for the 'post-ED' phase (acute inpatient transfer, subacute inpatient transfer, hospital at home, discharge home, or residential care) and the 'pre-ED' phase. The intervention outcomes were aligned with the aim (QAIM), which aims to improve patient care experience, enhance population health, optimise efficiency, and enhance staff satisfaction.

CONCLUSIONS

This study found that there was a wide range of interventions used to address patient flow, but the effectiveness of these interventions varied, and most interventions were focused on the ED. Interventions for the remainder of the patient journey were largely neglected. The metrics reported were mainly focused on efficiency measures rather than addressing all quadrants of the quadruple aim. Further research is needed to investigate and enhance the effectiveness of interventions outside the ED in improving ED patient flow. It is essential to develop interventions that relate to all three phases of patient flow: pre-ED, within-ED, and post-ED.

Overcrowding in emergency departments: an overview of reviews describing global solutions and their outcomes

Emergency Department (ED) crowding is defined as a situation wherein the demands of emergency services overcome the ability of a department to provide high-quality care within an appropriate time frame. There is a need for solutions, as the harms of crowding impact patients, staff, and healthcare spending. An overview of ED crowding was previously published by our group, which outlines these global issues. The problem of overcrowding in emergency departments has emerged as a global public health concern, and several healthcare agencies have addressed the issue and proposed possible solutions at each level of emergency care. There is no current literature summarizing the extensive research on interventions and solutions, thus there is a need for data synthesis to inform policymakers in this field. The aim of this overview was to summarize the interventions at each level of emergency care: input, throughput, and output. The methodology was supported by the current PRIOR statement for an overview of reviews. The study summarized twenty-seven full-text systematic reviews, which encompassed three hundred and eight primary studies. The results of the summary displayed a requirement for increasing studies in input and output interventions, as these showed the best outcomes with regard to ED crowding metrics. Moreover, the results displayed heterogeneous results at each level of ED care; these reflected that generally solutions have not been matched to specific problems facing regional centres. Thus, individual factors need to be considered when implementing solutions in Emergency Departments.

The Impact of Team Triage Method on Emergency Department Performance Indexes: A quasi-interventional study

Introduction

One of the effective methods of patient triage in the emergency department (ED) is the use of team triage, including physicians and nurses. Considering that there is no conclusive evidence about the effectiveness of team triage, this study aimed to investigate the effect of the team triage method on ED performance indexes.

Methods

The present study is a quasi-interventional study in which 200 patients were referred to the ED in the hospitals of Tabriz in 2020. Participants were randomly assigned to two groups (team triage and conventional triage) and were evaluated. Data were collected by a three-part questionnaire including the participants' demographic characteristics, the five-level triage form, and Press-Ganey satisfaction questionnaire were used. Data were analyzed by SPSS.22 statistical software.

Results

The results showed that the mean score of waiting time for the first physician visit in team triage was statistically significantly lower than the conventional triage (P = 0.001). Furthermore, the mean score of waiting time for receiving the first treatment in team triage was statistically significantly lower than the conventional triage (P = 0.001). Finally, the mean score of patients' satisfaction in team and conventional triage was statistically significantly higher in team triage (P = 0.001).

Conclusion

The study findings revealed that the team triage method, in comparison to conventional triage, decrease the waiting time for receiving the first service and length of stay, but leads to more patient's satisfaction. Therefore, to improve the performance indicators of the ED, it is recommended that hospital managers use the team triage method.

Factors affecting the triage decision-making ability of emergency nurses in Northern China: A multi-center descriptive survey

INTRODUCTION

The quality of triage decision-making is a prerequisite for priority treatment of critically ill patients and effective utilization of medical resources. Figuring out how to improve triage decision-making is still a topic around the global emergency department. Hence, this study aims to promote an understanding of triage priority care and clarify the elements influencing triage decision-making ability, offering reference for the future to improve the quality of triage decision-making.

METHOD

A total of 404 emergency nurses from 11 tertiary hospitals in northern China were surveyed by questionnaire, of which 371 valid questionnaires were submitted (effective rate = 91.83 %). One hospital distributed the questionnaire face-to-face, and the other ten used online form.

RESULT

Prior to occupying triage jobs, only a quarter of participants(25.30 %)were qualified. Less than half of emergency nurses (46.60 %) reported taking part in the triage training program. The emergency nurses' triage decision-making ability score was 166.50 ± 26.90(95 %CI 163.75,169.24) in northern China. Gender(P = 0.003), case discussion(P = 0.024), secondary assessment(P = 0.020)and knowledge of triage consensus(P = 0.027) are independent factors influencing triage decision-making ability.

CONCLUSION

Emergency triage practices are less implemented in northern China. The triage decision-making ability of emergency nurses in northern China is at a low level. Providing emergency nurses with diverse opportunities to develop their triage skills, finding effective triage training content, form, and frequency, strengthening implement triage consensus, and wisely managing triage nurse resources would improve triage decision-making.

A systematic review to identify the challenges to achieving effective patient flow in public hospitals

This systematic review aims to uncover the challenges related to patient flow from a whole public hospital perspective and identify strategies to overcome these challenges. A search in Medline, Emcare and PubMed was conducted and 24 articles published in English, from 2015 to 2020, were selected in relation to patient flow challenges and strategies. Analysis of the articles was completed using a thematic approach to identify common themes in relation to the area of focus. Strategies from the literature were then aligned with the challenges to inform areas of potential improvement in relation to patient flow. The themes generated included Teamwork, Collaboration and Communication; Public Hospitals as complex systems; Timely discharge; Policy, Process and Decision-making; and Resources-capacity and demand. The key finding is that a whole system approach is required to improve patient flow in public hospitals. When effective patient flow is achieved, demand and capacity are matched, increasing patient access to the health service and enabling the resources required to provide high quality patient care. The findings will create a better understanding of improving patient flow in public hospitals.

The FRISK (Fracture Risk)-A New Tool to Indicate the Probability of Fractures

Increasing patient inflow into the emergency department makes it necessary to optimize triage management. The scope of this work was to determine simple factors that could detect fractures in patients without the need for specialized personnel. Between 2014 and 2015, 798 patients were admitted to an orthopedic emergency department and prospectively included in the study. The patients received a questionnaire before contacting the doctor. Objective and subjective data were evaluated to determine fracture risk for the upper and lower extremities. The highest risk for fractures in one region was the hip (73.21%; n = 56), followed by the wrist (60.32%; n = 63) and the femoral shaft (4 of 7, 57.14%; n = 7). The regions with the lowest risk were the knee (8.41%; n = 107), the ankle (18.29%; n = 164), and the forearm shaft (30.00%; n = 10). Age was a predictor for fracture: patients older than 59 years had a risk greater than 59.26%, and patients older than 90 years had a risk greater than 83.33%. The functional questions could exclude fractures. Three factors seem to be able to predict fracture risk: the injured region, the patient's age, and a functional question. They can be used for a probatory heuristic that needs to be proven in a prospective way.

Reducing Crowding in Emergency Departments With Early Prediction of Hospital Admission of Adult Patients Using Biomarkers Collected at Triage: Retrospective Cohort Study

BACKGROUND

Emergency department crowding continues to threaten patient safety and cause poor patient outcomes. Prior models designed to predict hospital admission have had biases. Predictive models that successfully estimate the probability of patient hospital admission would be useful in reducing or preventing emergency department "boarding" and hospital "exit block" and would reduce emergency department crowding by initiating earlier hospital admission and avoiding protracted bed procurement processes.

OBJECTIVE

To develop a model to predict imminent adult patient hospital admission from the emergency department early in the patient visit by utilizing existing clinical descriptors (ie, patient biomarkers) that are routinely collected at triage and captured in the hospital's electronic medical records. Biomarkers are advantageous for modeling due to their early and routine collection at triage; instantaneous availability; standardized definition, measurement, and interpretation; and their freedom from the confines of patient histories (ie, they are not affected by inaccurate patient reports on medical history, unavailable reports, or delayed report retrieval).

METHODS

This retrospective cohort study evaluated 1 year of consecutive data events among adult patients admitted to the emergency department and developed an algorithm that predicted which patients would require imminent hospital admission. Eight predictor variables were evaluated for their roles in the outcome of the patient emergency department visit. Logistic regression was used to model the study data.

RESULTS

The 8-predictor model included the following biomarkers: age, systolic blood pressure, diastolic blood pressure, heart rate, respiration rate, temperature, gender, and acuity level. The model used these biomarkers to identify emergency department patients who required hospital admission. Our model performed well, with good agreement between observed and predicted admissions, indicating a well-fitting and well-calibrated model that showed good ability to discriminate between patients who would and would not be admitted.

CONCLUSIONS

This prediction model based on primary data identified emergency department patients with an increased risk of hospital admission. This actionable information can be used to improve patient care and hospital operations, especially by reducing emergency department crowding by looking ahead to predict which patients are likely to be admitted following triage, thereby providing needed information to initiate the complex admission and bed assignment processes much earlier in the care continuum.

Usability Testing of a Patient-Centered Mobile Health App for Supporting and Guiding the Pediatric Emergency Department Patient Journey: Mixed Methods Study

BACKGROUND

Patient experience in emergency departments (EDs) remains often suboptimal and can be a source of stress, particularly in pediatric settings. In an attempt to support patients and their families before, during, and after their visit to a pediatric ED, a mobile health (mHealth) app was developed by a multidisciplinary team based on patient-centered care principles.

OBJECTIVE

This study aims to evaluate the usability (effectiveness, efficiency, and satisfaction) of a new mHealth app, InfoKids, by potential end users through usability testing.

METHODS

The app was assessed through an in-laboratory, video-recorded evaluation in which participants had to execute 9 goal-oriented tasks, ranging from account creation to the reception of a diagnostic sheet at the end of the emergency care episode. Effectiveness was measured based on the task completion rate, efficiency on time on task, and user satisfaction according to answers to the System Usability Scale questionnaire. Think-aloud usability sessions were also transcribed and analyzed. Usability problems were rated for their severity and categorized according to ergonomic criteria.

RESULTS

A total of 17 parents participated in the study. The overall completion rate was 97.4% (149/153). Overall, they reported good effectiveness, with the task successfully completed in 88.2% (135/153) of cases (95% CI 83%-93%). Each task, with the exception of the first, created difficulties for some participants but did not prevent their completion by most participants. Users reported an overall good to excellent perceived usability of the app. However, ergonomic evaluation identified 14 usability problems occurring 81 time. Among these, 50% (7/14) were serious as their severity was rated as either major or catastrophic and indicated areas of improvements for the app. Following the suggested usability improvements by participants, mitigation measures were listed to further improve the app and avoid barriers to its adoption.

CONCLUSIONS

Usability of the InfoKids app was evaluated as good to excellent by users. Areas of improvement were identified, and mitigation measures were proposed to inform its development toward a universal app for all ED patients visiting a digitalized institution. Its contribution could also be useful in paving the way for further research on mobile apps aimed at supporting and accompanying patients in their care episodes, as research in this area is scarce.

Strategies to reduce waiting times in outpatient rehabilitation services for adults with physical disabilities: A systematic literature review

Objective

Identifying effective strategies to reduce waiting times is a crucial issue in many areas of health services. Long waiting times for rehabilitation services have been associated with numerous adverse effects in people with disabilities. The main objective of this study was to conduct a systematic literature review to assess the effectiveness of service redesign strategies to reduce waiting times in outpatient rehabilitation services for adults with physical disabilities.

Methods

We conducted a systematic review, searching three databases (MEDLINE, CINAHL and EMBASE) from their inception until May 2021. We identified studies with comparative data evaluating the effect of rehabilitation services redesign strategies on reducing waiting times. The Mixed Methods Appraisal Tool was used to assess the methodological quality of the studies. A narrative synthesis was conducted.

Results

Nineteen articles including various settings and populations met the selection criteria. They covered physiotherapy ( n = 11), occupational therapy ( n = 2), prosthetics ( n = 1), exercise physiology ( n = 1) and multidisciplinary ( n = 4) services. The methodological quality varied ( n = 10 high quality, n = 6 medium, n = 3 low); common flaws being missing information on the pre-redesign setting and characteristics of the populations. Seven articles assessed access processes or referral management strategies (e.g. self-referral), four focused on extending/modifying the roles of service providers (e.g. to triage) and eight changed the model of care delivery (e.g. mode of intervention). The different redesign strategies had positive effects on waiting times in outpatient rehabilitation services.

Conclusions

This review highlights the positive effects of many service redesign strategies. These findings suggest that there are several effective strategies to choose from to reduce waiting times and help better respond to the needs of persons experiencing physical disabilities.

Validation of the National Early Warning Score (NEWS)-2 for adults in the emergency department in a tertiary-level clinic in Colombia: Cohort study

The National Early Warning Score (NEWS)-2 is an early warning scale that is used in emergency departments to identify patients at risk of clinical deterioration and to help establish rapid and timely management. The objective of this study was to determine the validity and prediction of mortality using the NEWS2 scale for adults in the emergency department of a tertiary clinic in Colombia.A prospective observational study was conducted between August 2018 and June 2019 at the Universidad de La Sabana Clinic.The nursing staff in the triage classified the patients admitted to the emergency room according to Emergency Severity Index and NEWS2. Demographic data, physiological variables, admission diagnosis, mortality outcome, and comorbidities were extracted.Three thousand nine hundred eighty-six patients were included in the study. Ninety-two (2%) patients required intensive care unit management, with a mean NEWS2 score of 7. A total of 158 patients died in hospital, of which 63 were women (40%). Of these 65 patients required intensive care unit management. The receiver operating characteristic curve for NEWS2 had an area of 0.90 (CI 95%: 0.87-0.92). A classification and score equivalency analysis was performed between triage and the NEWS2 scale in terms of mortality. Of the patients classified as triage I, 32.3% died, and those who obtained a NEWS2 score greater than or equal to 10 had a mortality of 38.6%.Among our population, NEWS2 was not inferior in its area under the receiver operating characteristic curve when predicting mortality than triage, and the cutoff point for NEWS2 to predict in-hospital mortality was higher.

Identifying Strategies for the Management of Interruptions for Novice Triage Nurses Using an Online Modified Delphi Method

PURPOSE

To use the Delphi Method to identify strategies used by triage nurses to effectively manage interruptions.

DESIGN

This study was based on the concepts of Benner's Novice to Expert Model. An online, modified Delphi approach was used to engage triage, education, and operational management experts in generating consensus recommendations on successful strategies to address triage interruptions in the emergency department.

METHODS AND ANALYSIS

A panel of nine triage, education, and operational management experts were selected based on their publication and presentation history. This panel participated in three Delphi rounds, providing individual responses during each round. All responses were entered into a RedCap database, which allowed research team members to synthesize the results and return summaries to the participants. Final consensus was reached among this panel regarding recommendations for successful strategies to address triage interruptions that can be encompassed in a training module. The experts were then asked to identify the best instructional modality for teaching each of the interruption management strategies.

FINDINGS

Eight strategies to mitigate the impact of interruptions were identified: (a) ensure nurses understand impact of interruptions; (b) ensure nurses understand consequences of interruptions on cognitive demands of healthcare workers that could influence behavior and lead to errors; (c) apologize to current patient before tending to interruption and give expectation of when you will return; (d) triage the interruption and decide to (i) ignore interruption, (ii) acknowledge, but delay servicing, interruption, or (iii) acknowledge and service interruption, delaying completion of interrupted task; (e) identify urgent communication as anything clinically significant that impacts the patient immediately or requires immediate intervention; (f) use focused questions to clarify whether interruption can wait; (g) redirect nonpriority interruptions; and (h) finish safety-critical task or tasks near completion before tending to an interruption. The Delphi participants recommended the best teaching modality was simulation for six of the strategies.

CONCLUSIONS

Participants agreed that there are strategies that can be taught to novice triage nurses to mitigate the impact of interruptions. The experts in operations management, emergency nursing, and education agree that creating simulations to teach each of these strategies is an effective way to educate nurses.

CLINICAL RELEVANCE

Interruptions impact the quality of care provided to patients. Training nurses to prevent interruptions and mitigate the impact of interruptions when they occur has the potential to improve patient outcomes.

Emergency department provider in triage: assessing site-specific rationale, operational feasibility, and financial impact

Emergency department (ED) crowding is recognized as a critical threat to patient safety, while sub-optimal ED patient flow also contributes to reduced patient satisfaction and efficiency of care. Provider in triage (PIT) programs-which typically involve, at a minimum, a physician or advanced practice provider conducting an initial screening exam and potentially initiating treatment and diagnostic testing at the time of triage-are frequently endorsed as a mechanism to reduce ED length of stay (LOS) and therefore mitigate crowding, improve patient satisfaction, and improve ED operational and financial performance. However, the peer-reviewed evidence regarding the impact of PIT programs on measures including ED LOS, wait times, and costs (as variously defined) is mixed. Mechanistically, PIT programs exert their effects by initiating diagnostic work-ups earlier and, sometimes, by equipping triage providers to directly disposition patients. However, depending on local contextual factors-including the co-existence of other front-end interventions and delays in ED throughput not addressed by PIT-we demonstrate how these features may or may not ultimately translate into reduced ED LOS in different settings. Consequently, site-specific analysis of the root causes of excessive ED LOS, along with mechanistic assessment of potential countermeasures, is essential for appropriate deployment and successful design of PIT programs at individual EDs. Additional motivations for implementing PIT programs may include their potential to enhance patient safety, patient satisfaction, and team dynamics. In this conceptual article, we address a gap in the literature by demonstrating the mechanisms underlying PIT program results and providing a framework for ED decision-makers to assess the local rationale for, operational feasibility of, and financial impact of PIT programs.

Triage practice in emergency departments in tertiary hospitals across China: A multicenter national descriptive survey

Triage procedure remains at a developing stage in mainland China, and few studies have reported the current status. This study aimed to explore the triage practices presently implemented in emergency departments in mainland China. A descriptive online national survey was administered to nurses with experience in emergency department triage who worked in 64 hospitals in 2019. A total of 361 participants completed the survey. Only 210 nurses (58.2%) used triage systems. Approximately 5% of the participants reported that no nurse was allocated to triage during the evening and night shifts in their emergency departments. Most participants had fewer than 5 years of nursing experience (47%) and emergency nursing experience (58.2%) before fulfilling the triage role. This study shows the variability in triage guidelines as well as the inconsistency between different hospitals in nurses' entry qualifications to triage, in hospital workforce arrangements, and in triage training. These problems underscore the need to unify triage guidelines and to establish reasonable entry qualifications and appropriate workforce arrangements for triage nurses that ensure high triage quality and high levels of patient safety.

Exploring overcrowding trends in an inner city emergence department in the UK before and during COVID-19 epidemic

BACKGROUND

The COVID-19 pandemic and the associated lockdowns have caused significant disruptions across society, including changes in the number of emergency department (ED) visits. This study aims to investigate the impact of three pre-COVID-19 interventions and of the COVID-19 UK-epidemic and the first UK national lockdown on overcrowding within University College London Hospital Emergency Department (UCLH ED). The three interventions: target the influx of patients at ED (A), reduce the pressure on in-patients' beds (B) and improve ED processes to improve the flow of patents out from ED (C).

METHODS

We collected overcrowding metrics (daily attendances, the proportion of people leaving within 4 h of arrival (four-hours target) and the reduction in overall waiting time) during 01/04/2017-31/05/2020. We then performed three different analyses, considering three different timeframes. The first analysis used data 01/04/2017-31/12-2019 to calculate changes over a period of 6 months before and after the start of interventions A-C. The second and third analyses focused on evaluating the impact of the COVID-19 epidemic, comparing the first 10 months in 2020 and 2019, and of the first national lockdown (23/03/2020-31/05/2020).

RESULTS

Pre-COVID-19 all interventions led to small reductions in waiting time (17%, p < 0.001 for A and C; an 9%, p = 0.322 for B) but also to a small decrease in the number of patients leaving within 4 h of arrival (6.6,7.4,6.2% respectively A-C,p < 0.001). In presence of the COVID-19 pandemic, attendance and waiting time were reduced (40% and 8%; p < 0.001), and the number of people leaving within 4 h of arrival was increased (6%,p < 0.001). During the first lockdown, there was 65% reduction in attendance, 22% reduction in waiting time and 8% increase in number of people leaving within 4 h of arrival (p < 0.001). Crucially, when the lockdown was lifted, there was an increase (6.5%,p < 0.001) in the percentage of people leaving within 4 h, together with a larger (12.5%,p < 0.001) decrease in waiting time. This occurred despite the increase of 49.6%(p < 0.001) in attendance after lockdown ended.

CONCLUSIONS

The mixed results pre-COVID-19 (significant improvements in waiting time with some interventions but not improvement in the four-hours target), may be due to indirect impacts of these interventions, where increasing pressure on one part of the ED system affected other parts. This underlines the need for multifaceted interventions and a system-wide approach to improve the pathway of flow through the ED system is necessary. During 2020 and in presence of the COVID-19 epidemic, a shift in public behaviour with anxiety over attending hospitals and higher use of virtual consultations, led to notable drop in UCLH ED attendance and consequential curbing of overcrowding. Importantly, once the lockdown was lifted, although there was an increase in arrivals at UCLH ED, overcrowding metrics were reduced. Thus, the combination of shifted public behaviour and the restructuring changes during COVID-19 epidemic, maybe be able to curb future ED overcrowding, but longer timeframe analysis is required to confirm this.

The Effect of Homelessness on Patient Wait Times in the Emergency Department

BACKGROUND

Prolonged emergency department (ED) wait times could potentially lead to increased morbidity and mortality. While previous work has demonstrated disparities in wait times associated with race, information about the relationship between experiencing homelessness and ED wait times is lacking.

OBJECTIVES

The purpose of this study was to explore the relationship between residence status (undomiciled vs. domiciled) and ED wait times. We hypothesized that being undomiciled would be associated with longer wait times.

METHODS

We obtained data from the National Hospital Ambulatory Medical Care Survey from 2014 to 2017. We compared wait times in each triage category using t tests. We used multivariate linear regression to explore associations between residence status and wait times while controlling for other patient- and hospital-level variables.

RESULTS

On average, undomiciled patients experienced significantly longer mean ED wait times than domiciled patients (53.4 vs. 38.9 min; p < 0.0001). In the multivariate model, undomiciled patients experienced significantly different wait times by 15.5 min (p = 0.0002). Undomiciled patients experienced increasingly longer waits vs. domiciled patients for the emergent and urgent triage categories (+33.5 min, p < 0.0001, and +22.7 min, p < 0.0001, respectively).

CONCLUSIONS

Undomiciled patients experience longer ED wait times when compared with domiciled patients. This disparity is not explained by undomiciled patients seeking care in the ED for minor illness, because the disparity is more pronounced for urgent and emergent triage categories.

Team triage increases discharges and decreases time to discharge without increasing test ordering

OBJECTIVES

Emergency department (ED) crowding is detrimental to patients and staff. During traditional triage, nurses evaluate patients and identify their level of emergency. During team triage, physicians and/or nurse practitioners (NPs) and physician assistants (PAs) place orders, laboratory results, intravenous lines (IVs), and imaging in triage. Team triage improves access to testing and decreases length of stay. However, ordering practices in team triage may lead to overtesting.

METHODS

This is a retrospective review of patients seen before and after a team triage process was established. Percentage of patients receiving testing and the diagnostic yields of troponins, lactates, international normalized ratios (INRs), blood cultures, glomerular filtration rates (GFR), and head computed tomography (CT) images were studied.

RESULTS

A total of 704 traditionally triaged patients and 862 team triaged patients met inclusion criteria. Comparing traditional versus team triaged patients, the proportion of patients discharged was 0.44 versus 0.53 (P < 0.001), and the length of stay to discharge was 417 versus 375 minutes (P = 0.003). Comparing traditional versus team triage, a head CT was obtained 12.5% versus 5.7% (P < 0.001) of the time with diagnostic yield 45.5% versus 52% (not significant), troponin was obtained 51.3% versus 45.9% (not significant) of the time with diagnostic yield 14.9% versus 13.9% (not significant), lactate was obtained 41.6% versus 32.1% (P = 0.011) of the time with diagnostic yield 18.4% versus 12.3% (not significant), INR was obtained 70.2% versus 55.8% (P = 0.007) of the time with diagnostic yield 15.8% versus 10.5% (P = 0. 042), GFR was obtained 99.3% versus 98.4% (not significant) of the time with diagnostic yield 18.9% versus 13.7% (P = 0.02), and blood cultures were obtained 23.4% versus 7.3% (P < 0.001) of the time with diagnostic yield 7.3% versus 9.3% (not significant).

CONCLUSION

Compared with traditional triage, the team triage process increased discharges and decreased time to discharge, but did not lead to increased testing or decreased diagnostic yield.

The role and contribution of nurses to patient flow management in acute hospitals: A systematic review of mixed methods studies

BACKGROUND

Increased overcrowding in the emergency department is a potential threat to the quality and safety of patient care. Innovative ways are needed to explore overcrowding, the variables affecting patient flow and interventions necessary for future flow improvement.

AIMS AND OBJECTIVES

The aim of this review is to explore nurses' role(s) and their contribution to maintaining patient flow in acute hospitals through emergency departments.

METHODOLOGY

A systematic review of mixed studies (qualitative, quantitative and mixed-method) using narrative synthesis was undertaken. Five major databases-PubMed, CINHAL, BNI, ASSIA and SCOPUS-were searched to identify appropriate primary and secondary studies. Selected studies were critically appraised with a modified CASP tool. Data extraction and analysis was undertaken using narrative synthesis.

RESULTS

In total, 34 articles (31 primary studies and three systematic reviews) met the inclusion criteria. This systematic review is informed by studies from several countries, including the UK, US, Australia, Canada, and the Netherlands. The qualitative arm of this review explored both the role and function of nurses, as well as their experiences and perspectives of the patient flow process, while the quantitative arm investigated nurses' contribution to patient flow in terms of length of stay (LOS), triage time, and other associated performance data.

FINDINGS

Nurses' contribution to patient flow spanned their operational, strategic, and expanded roles. Strategic and expanded nursing roles offered the possibility of reducing LOS, triage time, and ED crowding in addition to improving the experience of patients and staff. Nurses in operational roles deployed experiential knowledge pertaining to several invisible aspects of patient flow challenges thereby facilitating decision-making for strategic flow improvement. The experiential knowledge and skills of these nursing roles are central to the success of flow-related interventions. However, the effects of emotional labour (e.g. conflicts, frustrations) of patient flow processes on nurses are significant and may have unaccounted for transaction costs and consequences that need acknowledging in order to be addressed by managers and policy makers.

CONCLUSIONS AND RECOMMENDATIONS

Policy-makers and senior managers need to capitalise on nurses' experiential knowledge and skills to enhance the strategic design and development of flow management in acute hospitals. Recommendations from this review have potential to deploy those skills and knowledge in flow improvement.

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.

Strategies to measure and improve emergency department performance: a scoping review

Background

Over the last two decades, Emergency Department (ED) crowding has become an increasingly common occurrence worldwide. Crowding is a complex and challenging issue that affects EDs’ capacity to provide safe, timely and quality care. This review aims to map the research evidence provided by reviews to improve ED performance.

Methods and findings

We performed a scoping review, searching Cochrane Database of Systematic Reviews, Scopus, EMBASE, CINAHL and PubMed (from inception to July 9, 2019; prospectively registered in Open Science Framework https://osf.io/gkq4t/). Eligibility criteria were: (1) review of primary research studies, published in English; (2) discusses a) how performance is measured in the ED, b) interventions used to improve ED performance and their characteristics, c) the role(s) of patients in improving ED performance, and d) the outcomes attributed to interventions used to improve ED performance; (3) focuses on a hospital ED context in any country or healthcare system. Pairs of reviewers independently screened studies’ titles, abstracts, and full-texts for inclusion according to pre-established criteria. Discrepancies were resolved via discussion. Independent reviewers extracted data using a tool specifically designed for the review. Pairs of independent reviewers explored the quality of included reviews using the Risk of Bias in Systematic Reviews tool. Narrative synthesis was performed on the 77 included reviews. Three reviews identified 202 individual indicators of ED performance. Seventy-four reviews reported 38 different interventions to improve ED performance: 27 interventions describing changes to practice and process (e.g., triage, care transitions, technology), and a further nine interventions describing changes to team composition (e.g., advanced nursing roles, scribes, pharmacy). Two reviews reported on two interventions addressing the role of patients in ED performance, supporting patients’ decisions and providing education. The outcomes attributed to interventions used to improve ED performance were categorised into five key domains: time, proportion, process, cost, and clinical outcomes. Few interventions reported outcomes across all five outcome domains.

Conclusions

ED performance measurement is complex, involving automated information technology mechanisms and manual data collection, reflecting the multifaceted nature of ED care. Interventions to improve ED performance address a broad range of ED processes and disciplines.

Emergency department overcrowding : Analysis and strategies to manage an international phenomenon

Overcrowding in emergency departments is a common and worldwide phenomenon, which is widely reported even in the lay press. Strategies to address this incriminating situation for patients, nurses, physicians and hospital administrators are urgently needed. The current review presents an analysis of the overcrowding problem as well as strategies to answer overcrowding situations.

Defining "Swarming" as a New Model to Optimize Efficiency and Education in an Academic Emergency Department

BACKGROUND

Academic emergency medicine is a constant balance between efficiency and education. We developed a new model called swarming, where the bedside nurse, resident, and attending/fellow simultaneously evaluate the patient, including initial vital signs, bedside triage, focused history and physical examination, and discussion of the treatment plan, thus creating a shared mental model.

OBJECTIVES

To combine perceptions from trainee physicians, supervising physicians, nurses, and families with in vivo measurements of emergency department swarms to better conceptualize the swarming model.

METHODS

This mixed methods study was conducted using a convergent design. Qualitative data from focus groups with nurses, residents, and attendings/fellows were analyzed using directed content analysis. Swarming encounters were observed in real time; durations of key aspects and family satisfaction scores were analyzed using descriptive statistics. The qualitative and quantitative findings were integrated a posteriori.

RESULTS

From the focus group data, 54 unique codes were identified, which were grouped together into five larger themes. From 39 swarms, mean (±SD) time (minutes) spent in patient rooms: nurses = 6.8 (±3.0), residents = 10.4 (±4.1), and attendings/fellows = 9.4 (±4.3). Electronic documentation was included in 67% of swarms, and 39% included orders initiated at the bedside. Mean (±SD) family satisfaction was 4.8 (±0.7; Likert scale 1-5).

CONCLUSIONS

Swarming is currently implemented with significant variability but results in high provider and family satisfaction. There is also consensus among physicians that swarming improves trainee education in the emergency setting. The benefits and barriers to swarming are underscored by the unpredictable nature of the ED and the observed variability in implementation. Our findings provide a critical foundation for our efforts to refine, standardize, and appraise our swarming model.

A Multicenter Observational Prospective Cohort Study of Association of the Prehospital National Early Warning Score 2 and Hospital Triage with Early Mortality

Aim of the Study

To evaluate the ability of the prehospital National Early Warning Score 2 scale (NEWS2) to predict early mortality (within 48 hours) after the index event based on the triage priority assigned for any cause in the emergency department.

Methods

This is a multicenter longitudinal observational cohort study on patients attending Advanced Life Support units and transferred to the emergency department of their reference hospital. We collected demographic, physiological, and clinical variables, main diagnosis, and hospital triage level as well as mortality. The main outcome variable was mortality from any cause within two days of the index event.

Results

Between April 1 and November 30, 2018, a total of 1054 patients were included in our study. Early mortality within the first 48 hours after the index event affected 55 patients (5.2%), of which 23 cases (41.8%) had causes of cardiovascular origin. In the stratification by triage levels, the AUC of the NEWS2 obtained for short-term mortality varied between 0.77 (95% CI: 0.65-0.89) for level I and 0.94 (95% CI: 0.79-1) for level III.

Conclusions

The Prehospital Emergency Medical Services should evaluate the implementation of the NEWS2 as a routine evaluation, which, together with the structured hospital triage system, effectively serves to predict early mortality and detect high-risk patients.

Interventions to improve patient flow in emergency departments: an umbrella review

OBJECTIVES

Patient flow and crowding are two major issues in ED service improvement. A substantial amount of literature exists on the interventions to improve patient flow and crowding, making it difficult for policymakers, managers and clinicians to be familiar with all the available literature and identify which interventions are supported by the evidence. This umbrella review provides a comprehensive analysis of the evidence from existing quantitative systematic reviews on the interventions that improve patient flow in EDs.

METHODS

An umbrella review of systematic reviews published between 2000 and 2017 was undertaken. Included studies were systematic reviews and meta-analyses of quantitative primary studies assessing an intervention that aimed to improve ED throughput.

RESULTS

The search strategy yielded 623 articles of which 13 were included in the umbrella review. The publication dates of the systematic reviews ranged from 2006 to 2016. The 13 systematic reviews evaluated 26 interventions: full capacity protocols, computerised provider order entry, scribes, streaming, fast track and triage. Interventions with similar characteristics were grouped together to produce the following categories: diagnostic services, assessment/short stay units, nurse-directed interventions, physician-directed interventions, administrative/organisational and miscellaneous. The statistical evidence from 14 primary randomised controlled trials (RCTs) was evaluated to determine if correlation or clustering of observations was considered. Only the fast track intervention had moderate evidence to support its use but the RCTs that assessed the intervention did not use statistical tests that considered correlation.

CONCLUSIONS

Overall, the evidence supporting the interventions to improve patient flow is weak. Only the fast track intervention had moderate evidence to support its use but correlation/clustering was not taken into consideration in the RCTs examining the intervention. Failure to consider the correlation of the data in the primary studies could result in erroneous conclusions of effectiveness.

Can interprofessional teamwork reduce patient throughput times? A longitudinal single-centre study of three different triage processes at a Swedish emergency department

OBJECTIVE

To determine the impact on emergency department (ED) throughput times and proportion of patients who leave without being seen by a physician (LWBS) of two triage interventions, where comprehensive nurse-led triage was first replaced by senior physician-led triage and then by interprofessional teamwork.

DESIGN

Single-centre before-and-after study.

SETTING

Adult ED of a Swedish urban hospital.

PARTICIPANTS

Patients arriving on weekdays 08:00 to 21:00 during three 1-year periods in the interval May 2012 to November 2015. A total of 185 806 arrivals were included.

INTERVENTIONS

Senior physicians replaced triage nurses May 2013 to May 2014. Interprofessional teamwork replaced the triage process on weekdays 08:00 to 21:00 November 2014 to November 2015.

MAIN OUTCOME MEASURES

Primary outcomes were the median time to physician (TTP) and the median length of stay (LOS). Secondary outcome was the LWBS rate.

RESULTS

The crude median LOS was shortest for teamwork, 228 min (95% CI 226.4 to 230.5) compared with 232 min (95% CI 230.8 to 233.9) for nurse-led and 250 min (95% CI 248.5 to 252.6) for physician-led triage. The adjusted LOS for the teamwork period was 16 min shorter than for nurse-led triage and 23 min shorter than for physician-led triage. The median TTP was shortest for physician-led triage, 56 min (95% CI 54.5 to 56.6) compared with 116 min (95% CI 114.4 to 117.5) for nurse-led triage and 74 min (95% CI 72.7 to 74.8) for teamwork. The LWBS rate was 1.9% for nurse-led triage, 1.2% for physician-led triage and 3.2% for teamwork. All outcome measure differences had two-tailed p values<0.01.

CONCLUSIONS

Interprofessional teamwork had the shortest length of stay, a shorter time to physician than nurse-led triage, but a higher LWBS rate. Interprofessional teamwork may be a useful approach to reducing ED throughput times.
