Intensive care unit admission from the emergency department in the setting of National Emergency Access Targets

PurposeSince the introduction of National Emergency Access Targets (NEATs) in 2012 there has been little research examining patients admitted to the intensive care unit (ICU).We assessed differences in baseline characteristics and outcomes of patients admitted from the Emergency Department (ED) to the ICU within 4 hours compared with patients who were not. MethodsThis retrospective observational study included all adults (≥18 years old) admitted to the ICU from the ED of Austin Hospital, Melbourne, Australia, between 1 January 2017 and 31st December 2019 inclusive. Results1544 patients were admitted from the ED to the ICU and 65% had an ED length of stay (EDLOS) > 4 hour. Such patients were more likely to be older, female, with less urgent triage category scores and lower illness severity. Sepsis and respiratory admission diagnoses, and winter presentations were significantly more prevalent in this group.After adjustment for confounders, patients with an EDLOS > 4 hours had lower hospital mortality; 8% v 21% (p = 0.029; OR, 1.62), shorter ICU length of stay 2.2 v 2.4 days (p = 0.043), but a longer hospital length of stay 6.2 v 6.8 days (p = < 0.001). ConclusionAlmost two thirds of patients breached the NEAT of 4 hours. These patients were more likely to be older, female, admitted in winter with sepsis and respiratory diagnoses, and have lower illness severity and less urgent triage categories. NEAT breach was associated with reduced hospital mortality but an increased hospital length of stay.

The impact of acute surgical unit rostering on National Emergency Access Targets during the COVID-19 pandemic: a single hospital experience.

BackgroundSurgical departments have been dramatically impacted by the novel coronavirus 19 (COVID‐19) pandemic, with the cancellation of elective cases and changes to the provision of emergency surgical care. The aim of this study was to determine whether structural changes made within our facility's surgical department during COVID‐19 altered National Emergency Access Target (NEAT) times and impacted on patient outcomes.MethodsEmergency surgical cases over a 4‐month time period were retrospectively collected and statistically analysed, divided into pre‐ and mid‐COVID‐19 pandemic.ResultsBaseline characteristics between the groups were comparable. There was a significant increase in consultant presence in theatre in the COVID group. There were also statistically significant reductions in NEAT times at each timepoint, although these did not meet national guidelines. There was no change in emergency surgical workload, complication rate or mortality rates within 30 days.ConclusionAny significant change to services requires a coordinated hospital‐wide approach, not just from a single department, and clinicians must continue to be wary of benchmarked times as the overall feasibility and safety of NEAT times has also been highlighted again.

Ecstasy and related drug consumption and the effect on emergency department resource use

BackgroundEcstasy and other recreational related drug use and substance related presentations to the emergency department (ED) are increasing. The aim of this study was to identify, quantify, and describe the ED resources used to care for patients diagnosed with ecstasy and related drug (ERD) use. MethodA retrospective case study design. ResultsEighty-nine patients (89%) needed one to one (n=25) and/or one to two nursing care (n=83). Security presence was required for 37 patients (37%) and the Emergency Psychiatric Service team reviewed 29 patients (29%). Most patients (n=80, 80%) received an Emergency Short Stay Unit admission, but continued to receive care in the ED, and were not transferred to the short stay unit (n=74, 92.5%). Most patients (n=86, 86%) were discharged home, after 5hr 49mins (median) in ED. ConclusionExtensive human resources were required to care for patients diagnosed with ERD use. Nursing staffing levels required to care for this patient cohort during times of peak presentations should be reviewed. It is important the government acknowledges the National Emergency Access Target is not suitable for all presenting patients. A dedicated model of care is recommended to support care requirements and reduce pressure on busy EDs.

Mental health presentations to a paediatric emergency department.

To explore trends in presentation and key performance indicators with respect to children seeking mental health services at The Prince Charles Hospital Children's Emergency Department (TPCH-CED), Brisbane. A retrospective audit was performed utilising data obtained from the local Emergency Department Information System for all mental health presentations between 1 January 2013 and 1 January 2018 to TPCH-CED. A total of 1078 children presented to TPCH-CED requiring mental health review between 2013 and 2018. Mental health presentations almost doubled over the 5 years (185 attendances in 2013; 342 in 2017); however, as a proportion of overall presentations, there was no significant increase. The percentage of mental health presentations meeting the National Emergency Access Target criteria dropped from 63% in 2013 to 39% in 2017 (P < 0.0001). Those requiring a mental health inpatient stay were more likely to have very extended length of stay within the CED. Suicidal ideation was the most common presenting complaint (72% of mental health presentations). Violence and aggression were noted in a consistent proportion of mental health presentations (4.4-12%). Despite failing to demonstrate an interval increase in the proportion of children presenting to TPCH-CED requiring mental health services, it is clear that children with mental health needs, like their adult counterparts, disproportionately experience delays to appropriate care when compared with children presenting with other emergency conditions. Ongoing research is warranted to assess standards of care and the impact of mental health presentations on CEDs.

Innovative pathway for managing children and adolescents with mental health concerns in the emergency department: An intervention feasibility study.

To investigate if an innovative clinical pathway for managing child and adolescent mental health (MH) ED presentations reduces average length of stay (LOS) and improves carer satisfaction. An intervention feasibility study at an ED. Participants were 5-17 years olds presenting with MH problems and their carers. ED medical officer (MO) led Kids Assessment Liaison for Mental Health (KALM) clinical pathway was implemented as an intervention and it was compared to Care as Usual pathway which involved ED MO and MH clinicians. Data were collected via the ED clinical data system and a carer survey. Data were analysed by using SAS v9.4 (SAS, Cary, NC, USA). Survey was compared using Fisher's exact test and LOS was compared using median quantile regression. Fifty (23%) patients used the KALM pathway and 169 (77%) the Care as Usual pathway. The median (min, max) LOS in hours for those on the KALM pathway was 4.13 (0.46, 11.55) compared to 5.09 (0.21, 19.12) for Care as Usual pathway (P = 0.1407). Fewer patients breached the National Emergency Access Target (NEAT) when the KALM pathway was used (56%, n = 28 vs 64%, n = 108, P = 0.252). There were no significant differences in the carer survey between the two care pathways. This study provides valuable information about the benefits of the KALM pathway in managing child and adolescent MH presentations to ED. This new pathway reduces the LOS in ED and improves carer experience compared to the usual care pathway.

Digital transformation of the emergency department-inpatient interface (EDii): integration for future innovation.

As the focus of clinicians and government shifts from speciality-based care to system-based key performance indicators such as the National Emergency Access Target (NEAT) or the 4-h rule, integration between emergency department (ED) and inpatient clinical workflows and information systems is becoming increasingly necessary. Such system measures drive the implementation of integrated electronic medical records (ieMR) to digitally integrate these workflows. The objective of this case study was to describe the impact of digital transformation of the ED-in-patient interface (EDii) of a large tertiary hospital on process measures and clinical outcomes for patients requiring emergency admission to hospital. Data were collected from routine clinical and administrative information systems to measure process and clinical outcome measures, including ED length of stay, compliance with the 4-h rule and in-patient mortality between 28 November 2014 and 28 February 2017. The 4-h rule compliance for all patients, as well as for the EDii group (admitted to hospital excluding short stay ward), declined after digitisation. There were 55 fewer deaths in the postintervention group (15% relative reduction; P = 0.02) and a 10% relative reduction in adjusted mortality as measured by the Hospital Standardised Mortality Ratio for emergency patients (eHSMR), which did not reach statistical significance. Digital deceleration in ED performance did occur with an ieMR rollout, but worsening of key patient outcomes was not observed.

When a health policy cuts both ways: Impact of the National Emergency Access Target policy on staff and emergency department performance.

To explore the impact of the Four-Hour Rule/National Emergency Access Target (4HR/NEAT) on staff and ED performance. A mixed-methods study design was used to link performance data from 16 participating hospitals with the experiences reported by 119 ED staff during policy implementation. Quantitative and qualitative measures were triangulated to identify the staff and organisational effects on hospital performance. An overall score was developed to categorise hospitals into: high, moderate and low performers, then compared with four qualitative themes: social factors, ED management, ED outcomes and 4HR/NEAT compliance. Key factors identified were stress and morale; intergroup dynamics; interaction with patients; resource management; education and training; financial incentives; impact on quality and safety; perceived improvements on access block and overcrowding. High performing hospitals reported increased stress and decreased morale, decreased staff-patient communication and staff shortages; significant changes in ED management and effective use of the whole-of-hospital approach. Moderate performing hospitals reported similar characteristics to a lesser degree, and the perception that 4HR/NEAT did not impact ED practice. Low performing hospitals also reported increased stress and low morale and a less effective whole-of-hospital approach. ED staff also reported a reduction in communication with patients. There was strong evidence of an association between high stress and low morale and the implementation of the 4HR/NEAT across all levels of performance. These adverse consequences of the 4HR/NEAT implementation indicate that a more nuanced approach to efficiency improvements is required. This would balance processes measured by 4HR/NEAT against a range of other clinical and organisational performance measures.

Time is of the essence: evaluation of emergency department triage and time performance in the preoperative management of acute abdomen.

Acute abdomen is a time-critical condition, which requires prompt diagnosis, initiation of first-line preoperative therapy and expedient surgical intervention. The earliest opportunity to intervene occurs at presentation to the emergency department triage. The aim of this audit was to evaluate the relationship between emergency triage and time performance measures in the preoperative management of abdominal emergencies. Retrospective audit of time performance measures of key clinical events from emergency triage. Patient characteristics, elapsed time from triage to commencement of fluid resuscitation, intravenous antibiotics and emergency surgery and post-operative outcomes were obtained from review of operative medical records data over a 1-year duration. There was variability in triage allocation of patients with acute abdomen requiring urgent surgery. Category 3 was the most commonly assigned triage category (65.6%). The majority of patients (94.8%) had initial clinical assessment within the National Emergency Access Target '4-hour' rule, and 41.7% seen within 1-h from triage. Despite this, in cases of intra-abdominal sepsis, there was nearly a fourfold elapsed time for first dose intravenous antibiotics, beyond the 1-h recommendation in the Sepsis Kills pathway. There was non-significant trend in faster overall time performances with successive higher triage category allocation. This study highlights an opportunity to consider alternative triage methods or fast-track of patients with acute abdomen to promote early surgical assessment, resuscitation, antibiotic therapy and definitive intervention.

Gaming National Emergency Access Target performance using Emergency Treatment Performance definitions and emergency department short stay units.

To evaluate potential gaming of the 4 h ED length of stay metric known as the National Emergency Access Target (NEAT) in Australia and Emergency Treatment Performance (ETP) in New South Wales (NSW). Descriptive statistical analysis was used to recalculate and compare the scores for NEAT and the NSW ETP using variations in the definitions of their measurement on 32 184 presentations during 2016. A computer simulation using a discrete event model illustrated the effect of the use of ED short stay beds on the ETP scores. Using the timestamp of the intent to discharge a patient, called, 'ready for departure' instead of the time of a patient physically leaving the department, resulted in an apparent 6% performance improvement. A local interpretation of the NSW state definition of the 'transferred' patient resulted in the ETP for 'admitted' patients improving by 16%. The discrete event model demonstrated that without changing patient length of stay, ETP scores can be improved by optimising the time of the admit decision or increasing the number of ED short stay beds. The opportunity of NEAT may be squandered unless gaming of the definitions and use of ED short stay beds is addressed. We argue that the longstanding issue of 'departure time' should be defined as 'physically leaving' the department, in accordance with the Australasian College for Emergency Medicine (ACEM) definition. Patient occupancy is a real measure of ED resource use and NSW and national recommendations should be adjusted. ACEM accreditation of EDs should include review of their application of NEAT definitions to ensure they truly reflect patient flow processes.

Perceptions and experiences of emergency department staff during the implementation of the four-hour rule/national emergency access target policy in Australia: a qualitative social dynamic perspective

BackgroundThe Four-Hour Rule or National Emergency Access Target policy (4HR/NEAT) was implemented by Australian State and Federal Governments between 2009 and 2014 to address increased demand, overcrowding and access block (boarding) in Emergency Departments (EDs). This qualitative study aimed to assess the impact of 4HR/NEAT on ED staff attitudes and perceptions. This article is part of a series of manuscripts reporting the results of this project.MethodsThe methodology has been published in this journal. As discussed in the methods paper, we interviewed 119 participants from 16 EDs across New South Wales (NSW), Queensland (QLD), Western Australia (WA) and the Australian Capital Territory (ACT), in 2015–2016. Interviews were recorded, transcribed, imported to NVivo 11 and analysed using content and thematic analysis.ResultsThree key themes emerged: Stress and morale, Intergroup dynamics, and Interaction with patients. These provided insight into the psycho-social dimensions and organisational structure of EDs at the individual, peer-to-peer, inter-departmental, and staff-patient levels.ConclusionFindings provide information on the social interactions associated with the introduction of the 4HR/NEAT policy and the intended and unintended consequences of its implementation across Australia. These themes allowed us to develop several hypotheses about the driving forces behind the social impact of this policy on ED staff and will allow for development of interventions that are rooted in the rich context of the staff’s experiences.

Nurse practitioners in the emergency department: Establishing a successful service

BackgroundA regional hospital emergency department was facing increasing patient presentations, medical workforce shortages and long delays for patients to be seen. Furthermore, a high percentage of low acuity ambulatory patients were not waiting to be seen. AimTo introduce a sustainable / long-term nurse practitioner (NP) led model of care to address the identified emergency department service requirements for low acuity ambulatory patients. MethodsA descriptive exploratory design was used to establish and monitor a NP model. Organisational support and a steering committee was used to monitor clinical safety and patient satisfaction. Data was collected in relation to number of patients seen, conditions managed by nurse practitioners, time to treatment, length of stay and compliments and complaints received. FindingsNPs within this service now comprise 10% of the treating clinician workforce, see 15% of total presentations, contribute to a reduction in waiting time, length of stay within the targeted cohort and meeting National Emergency Access Targets 95% of the time. DiscussionEstablishment of a NP model has been successful at addressing the needs of low acuity patients in the emergency department as evidenced by reduced waiting times, length of stay and customer satisfaction. We attribute this success to the following three key factors: targeting a patient population, commitment to the service and adaptability. ConclusionDevelopment of a dedicated NP model has enabled the emergency department to safely and sustainably provide care to low acuity ambulatory patients.

Violence and aggression in the intensive care unit: What is the impact of Australian National Emergency Access Target?

IntroductionViolence in healthcare settings is a concern for healthcare professionals and patients. Media reports, and debate within the healthcare profession, and the academic literature infer that workplaces such as intensive care units are becoming exposed to increasing violence. Increases in the incidence of violent behaviour are sometimes attributed to the increased pressure on emergency departments to accelerate the throughput of patients to meet targets. To ensure the wellbeing of patients and staff, there is a need to evaluate the impact of such targets. The aim in this study was to evaluate the incidence and to describe the context in which patients' aggressive and violent behaviours occurred since the introduction of the National Emergency Access Target in a local tertiary Australian intensive care unit. MethodsA retrospective examination of events triggering violence-related emergency codes from 12 months before the introduction of the National Emergency Access Target up until 12 months after its implementation (2011–2013). ResultsA small increase in the number of Code Grey/Code Black activation was identified after the introduction of the target (before = 18, after = 29). Admissions following drug overdoses, isolated head trauma, and cardiac arrest were the presentations most likely to have been associated with a violence-related emergency call. Female registered nurses, male critical care registered nurses, and clinical nurse specialists were the most at risk of occupational violence. Male nursing staff members were found to be more likely to be involved in incidences of verbal violence (p < 0.003). ConclusionAlthough there was a minimal increase in the overall number of emergencies triggered by violent behaviour, valuable information on the type of occupational violence occurring towards healthcare professionals and patients in this setting was found. We suggest that these findings add further important detail to the existing understanding of the problem of occupational violence. These detailed insights can further inform policy development, professional education, and practice.

Emergency department models of care in Queensland: a multisite cross-sectional study.

Objective The acuity and number of presentations being made to emergency departments (EDs) is increasing. In an effort to safely and efficiently manage this increase and optimise patient outcomes, innovative models of care (MOC) have been implemented. What is not clear is how these MOC reflect the needs of patients or relate to each other or to ED performance. The aim of this study was to describe ED MOC in Queensland, Australia. Methods Situated within a larger mixed-methods study, the present study was a cross-sectional study. In early 2015, leaders (medical directors and nurse managers) from public hospital EDs in Queensland were invited to complete a survey detailing ED activity, staffing profiles, treatment space, MOC and National Emergency Access Target (NEAT) performance. Routinely collected ED information system data was also used. Results Twenty of the 27 EDs invited participated in the study (response rate 74%). An extensive array of MOC were identified that were categorised into those that facilitate input, throughput and output from the ED. There was no consistent evidence as to the relative effectiveness of these MOC in achieving ED performance benchmarks, such as NEAT performance. Conclusion There is considerable variability in the MOC used throughout EDs in Queensland. A more complete analysis of the relative effectiveness of different MOC either in isolation or as part of a comprehensive approach would help inform more consistent MOC in Queensland EDs. What is known about the topic? MOC in any given ED are implemented in response to factors such as the geographical location of the hospital, hospital-specific characteristics and service profile, staffing profile and patient demographic profile. In the era of time-based targets, they may also serve to address a particular aspect of flow in the face of rising ED demand. Although many of the MOC attempt to deal with flow in a linear fashion, target specific phases of the ED journey or address particular patient cohorts, what is clear is that not all EDs are shaped and formed the same. What does this paper add? The study provides a comprehensive description of the varied models of care operating within Queensland public hospital EDs and how they relate to ED performance. A basic taxonomy of contemporary ED MOC is necessary to allow comparison between departments and inform decisions regarding safety, efficiency and cost-effectiveness. What are the implications to practitioners? A contemporary understanding of the presence and profile of ED MOC that currently exist within a network of hospitals and health services is important for managers, clinicians and patients to inform decision-making regarding the safety, clinical effectiveness and cost-effectiveness of these models. This understanding can also inform where and how further improvements in care delivery can progress.

Impact of the four-hour National Emergency Access Target on 30 day mortality, access block and chronic emergency department overcrowding in Australian emergency departments.

Previous research reported strong associations between ED overcrowding and mortality. We assessed the effect of the Four-Hour Rule (4HR) intervention (Western Australia (WA) 2009), then nationally rolled out as the National Emergency Access Target (Australia 2012) policy on mortality and patient flow. A longitudinal cohort study of a population-wide 4HR, for 16 hospitals across WA, New South Wales (NSW), Australian Capital Territory (ACT) and Queensland (QLD). Mortality trends were analysed for 2-4 years before and after 4HR using interrupted time series technique. Main outcomes included the effect of 4HR on patient flow markers; admitted 30 day mortality trends; and patient flow marker performance during the study period. There were 40 281 deaths from 952 726 emergency admissions. All jurisdictions, except ACT, had improved flow and access block after 4HR. Age-standardised mortality was decreasing before the intervention. Post-intervention, WA had a significant reduction in mortality rate of -0.28 per 1000 patients per quarter (P = 0.040) while QLD had mixed results and NSW/ACT trends did not change significantly. Meta-regression of aggregated data for hospitals grouped on flow performances did not show significant mortality changes associated with the policy. The 4HR was introduced as a means of driving hospital performance by applying a time target. Patient flow improved, but the evidence for mortality benefit is controversial with improvement only in WA. Further research with more representative data from a larger number of hospitals over a longer time across Australia is needed to increase statistical power to detect long-term effects of the policy.

Impact of an emergency department-run clinical decision unit on access block, ambulance ramping and National Emergency Access Target.

ED access block is an ongoing significant problem and has been associated with excess mortality. Multiple models of care have been studied in an effort to improve access block and other key performance indicators (KPIs) of ED. This present study describes the impact of a new model of care using an ED led, consultant run clinical decision unit (CDU) on performance, using a retrospective analysis of data for 9 month periods before and after the introduction of the CDU model of care. Primary outcomes were access block (percentage of patients admitted >8 h), discharge National Emergency Access Target (NEAT) adherence and Queensland Ambulance Service level three escalations. After the implementation of the CDU, access block significantly improved. There was a significant improvement in NEAT adherence. Total ambulance ramping time fell by 58% and ambulance service level three escalations fell from 21 to 5 post-CDU implementation. Overall there was no change to hospital mortality numbers. The percentage of patients that did not wait and 30 day representations showed a small but statistically significant decrease. In summary, this ED led, consultant run CDU model of care resulted in significantly improved performance on a range of KPIs, including improvement in access block and NEAT figures. The substantial improvements in ambulance ramping and escalations also indicated that the department was able to cope better with periods of high activity.

Paediatric mental and physical health presentations to emergency departments, Victoria, 2008-15.

To identify trends in presentations to Victorian emergency departments (EDs) by children and adolescents for mental and physical health problems; to determine patient characteristics associated with these presentations; to assess the relative clinical burdens of mental and physical health presentations. Secondary analysis of Victorian Emergency Minimum Dataset (VEMD) data. Participants, setting: Children and young people, 0-19 years, who presented to public EDs in Victoria, 2008-09 to 2014-15. Absolute numbers and proportions of mental and physical health presentations; types of mental health diagnoses; patient and clinical characteristics associated with mental and physical health presentations. Between 2008-09 and 2014-15, the number of mental health presentations increased by 6.5% per year, that of physical health presentations by 2.1% per year; the proportion of mental health presentations rose from 1.7% to 2.2%. Self-harm accounted for 22.5% of mental health presentations (11 770 presentations) and psychoactive substance use for 22.3% (11 694 presentations); stress-related, mood, and behavioural and emotional disorders together accounted for 40.3% (21 127 presentations). The rates of presentations for self-harm, stress-related, mood, and behavioural and emotional disorders each increased markedly over the study period. Patients presenting with mental health problems were more likely than those with physical health problems to be triaged as urgent (2014-15: 66% v 40%), present outside business hours (36% v 20%), stay longer in the ED (65% v 82% met the National Emergency Access Target), and be admitted to hospital (24% v 18%). The number of children who presented to Victorian public hospital EDs for mental health problems increased during 2008-2015, particularly for self-harm, depression, and behavioural disorders.

Why do 'fast track' patients stay more than four hours in the emergency department? An investigation of factors that predict length of stay.

Low-acuity 'fast track' patients represent a large portion of Australian EDs' workload and must be managed efficiently to meet the National Emergency Access Target. The current study determined the relative importance and estimated marginal effects of patient and system-related variables in predicting ED fast track patients who stayed longer than 4 h in the ED. Data for ED presentations between 1 July 2014 and 30 June 2015 were collected from a large regional Australian public hospital. Only 'fast track' patients were included in the analysis. A gradient boosting machine was used to predict which patients would have an ED length of stay greater or less than 4 h. The performance of the final model was tested using a validation data set that was withheld from the initial analysis. A total of 27 variables were analysed. The model's performance was very good (area under receiver operating characteristic curve 0.89, where 1.0 is perfect prediction). The five most important variables for predicting length of stay were time-dependent and system-related (not patient-related); these were the amount of time taken from when the patient arrived at the ED to: (i) order imaging; (ii) order pathology; (iii) request admission to hospital; (iv) allocate a clinician to care for the patient; and (v) handover a patient between ED clinicians. We identified the most important variables for predicting length of stay greater than 4 h for fast track patients in our ED. Identifying factors that influence length of stay is a necessary step towards understanding ED patient flow and identifying improvement opportunities.

Increased burden on metropolitan urological services: The era of the Australian National Emergency Access Targets (NEAT or the "4-h target").

Background:The National Emergency Access Targets (NEAT) was introduced in Australia in 2011 and guides the clearance of presentations within 4-h of initial presentation from the Emergency Department (ED). We aim to assess the impact of the introduction of NEAT on acute urological services at a large metropolitan center.Methods:A retrospective cohort study was performed and data were collected from electronic patient management systems. The control group was represented by ED presentations between June and September 2011, 1 year prior to the introduction of NEAT. The two study groups consisted of ED presentations between June and September 2012 and 2013, respectively. Outcome measures included time to the ureteric stent and scrotal exploration, inpatient length of stay (IPLOS), out-of-hours operating, and hospital mortality rates.Results:Across the three study periods, a total of 76,935 patients were assessed by the EDs of the health service. 225 urological inpatient episodes were included across all periods with a trend showing increasing numbers of admissions (P = 0.003). For patients admitted under the urological service: Waiting room time and ED length of stay decreased significantly (P < 0.001). Proportion of operative cases decreased insignificantly (P = 0.275). Time from emergency presentation to emergency ureteric stent remained unchanged, however, proportions of procedures performed out-of-hours showed an increasing trend (P < 0.001). A significant increase in inter-unit transfer was observed, however, median IPLOS and mortality for operative and nonoperative cases remain unchanged.Conclusions:Concerning urological admissions, the implementation of NEAT has been associated with improvement in ED key performance indicators. Such changes have been correlated with reductions in operative cases and increases in out-of-hours emergency operating. Further research is required to evaluate the direct effect of NEAT on urological patient care.

Use of medical emergency call data as a marker of quality of emergency department care in the post-National Emergency Access Target era.

Objectives Any new model of care should always be accompanied by rigorous monitoring to ensure that there are no negative consequences, especially any that impact upon patient safety. In 2013, 'THERMoSTAT' (Two- Hour Evaluation and Referral Model for Shorter Turnaround Times), an emergency department model of care developed by Royal Brisbane and Women's Hospital staff was launched to gain efficiencies and improve hospital National Emergency Access Target (NEAT) compliance. The aim of this study was to trial the use of medical emergency call data as a novel marker of the quality of care delivered by our emergency department. Methods Incidence of medical emergency calls for hospital emergency admission patients for the 2 years pre- and 1 year post-THERMoSTAT were compared after standardising for overall hospital activity. Results During the study period, hospital activity increased 10%, and the emergency department experienced a total of 222645 presentations, 68000 (30.5%) of which converted into an admission. THERMoSTAT improved NEAT compliance by 17% (from 57.7% to 74.9%) with no change in any patient-safety indicators. A total of 8432 medical emergency calls were made on 5930 patients, 2831 of whom were emergency admissions. After adjusting for hospital activity, there was no change in the average number of patients per week who triggered a medical emergency call after the introduction of THERMoSTAT. These results were reproduced when data was analysed for: total number of inpatients triggering calls; emergency admission patients; and emergency admission patients within the first 24h or first 4h of admission. Conclusions This is the first report to investigate the correlation between inpatient medical emergency call incidence and emergency department model of care. Medical emergency call data showed significant promise as a measure of morbidity and as a more direct, objective, simple, quantitative and meaningful measure of patient safety. What is known about the topic? It is well established that extended emergency department lengths of stay are associated with poorer patient outcomes. The corollary of this is not always true however; shorter emergency department length of stay does not automatically translate into better care. Although the underlying philosophy of NEAT is to enhance patient care, there is a risk of negative consequences if NEAT is seen as an end in itself. Many of the commonly used emergency department key performance indicators focus on the timeliness of care and there is a scarcity of easily quantifiable markers that reliably reflect the quality of that care. What does this paper add? This study builds on the concept of medical emergency call incidence as a marker of safety and quality. It explores the utility of using the number of medical emergency calls made in the first few hours of an emergency admission as an indicator of the quality of care delivered by the emergency department. This is significant because it introduces a measure that has a focus that embraces more than the timeliness of care only. What are the implications for practitioners? If medical emergency call incidence in early emergency admissions can be proven to accurately reflect emergency department quality of care then it would provide an easily monitored, objective, quantitative and prompt measure that evaluates dimensions other than timeliness.

Implementation and evaluation of a ‘Navigator’ role to improve emergency department throughput

BackgroundEmergency department overcrowding impacts patients, staff, and quality of care, and there is government pressure to optimize throughput and reduce waiting times. One solution for improving patient flow is the emerging ‘navigator’ role: a nurse that supports staff in care delivery; facilitating efficient and timely patient movement through the emergency department. MethodsA 20-week project was implemented to evaluate an emergency department nurse navigator role. A controlled trial was used. The navigator worked on a week-on-week-off basis, eight hours per day, seven days per week. Time-based and cost-associated outcomes were compared. ResultsData from nearly 20,000 presentations during the trial period were analysed. All outcomes were improved during the ten weeks the Navigator was working. A slight improvement in National Emergency Access Target compliance was shown, with an average of 4.5min per presentation saved. The labour cost associated with the time saved was estimated to be $170,000. ConclusionsThe results from this study indicate that for a relatively small investment, complementary nursing roles such as the navigator can impact emergency department patient flow. However, further studies are required to determine optimisation of the role. Relevance to practiceThis study provides rigorous evidence of the effects of a nurse navigator role on emergency department throughput. Whilst positive outcomes were demonstrated, suggesting a whole-of-system benefit, the magnitude of effect on a per-presentation basis was relatively small. Further studies are required to demonstrate the clinical relevance of such roles.
