Summer alcohol-related emergency department workload and occupancy in Australasia 2019-2022.

OBJECTIVE: Alcohol is a major public health issue and the ACEM funds regular 'snapshot' surveys of the prevalence of alcohol-related presentations in EDs. The present study uses these data to investigate ED occupancy and alcohol- and methamphetamine-related presentations at the time of the COVID-19 pandemic. METHODS: Survey-based point prevalence study of EDs in Australia and New Zealand conducted at 02:00 hours local time on the Saturday of the weekend before Christmas in 2019-2022. Primary outcomes were ED occupancy, the number of alcohol-related presentations and methamphetamine-related presentations in each ED at the time of survey. RESULTS: Seventy eight of a possible 152 hospitals answered all four surveys (51%, 95% confidence interval 43-59, individual yearly response rates ranged from 70.5% to 83.3%). The mean number of alcohol-related presentations in EDs at the snapshot time was 4.2 (95% confidence interval 3.2-5.2) in the 2019 survey and 3.8 (3.1-4.6) in 2022 with no significant variation over time. There was also no change in methamphetamine-related presentations which occurred at a lower level. There was a major increase in reported total ED occupancy - from 31.4 to 43.5 in Australia (P < 0.0001, paired t test) and from 22.8 to 38.7 in New Zealand (P = 0.0001). Subgroup analysis showed that both the number being treated and the number waiting to be seen increased, with little change in the number in observation units. CONCLUSIONS: The present study demonstrates that the COVID-19 pandemic did not affect summer alcohol-related ED presentations in Australasia but was associated with an unsustainable increase in ED crowding.

Access block in Australian emergency departments 2017-2020.

OBJECTIVE: To describe Australian ED workload over the period 2017-2020 using data from twice annual Access Block Point Prevalence Studies, and to identify any impact of the COVID-19 pandemic. METHODS: Retrospective analysis of demand and occupancy data provided by the Australasian College for Emergency Medicine accredited EDs in voluntary surveys at the start of June and September 2017-2020. Hospitals answering all surveys were grouped and compared by jurisdiction and role delineation. RESULTS: A total of 121 EDs were eligible, 63% supplied complete occupancy data and 53% complete demand data. Between the June 2017 and 2019 surveys, mean daily ED presentations increased by 11.4% (P = 0.0003). The number being treated at 10.00 hours rose by 27.7% (P < 0.0001) and those experiencing access block (waiting for an inpatient bed, been in ED more than 8 h) rose by 46.1% (P = 0.001). Between the June 2019 and 2020 surveys, ED presentations fell by an average of 12.6% (P < 0.0001), ward admissions were almost unchanged (-6.0%, P = NS), and patients who did not wait to be seen fell by 57.8% (P < 0.0001). Major Paediatric Referral hospitals reported a 28% decrease in presentations. By September 2020, only the state of Victoria (ongoing state of emergency) and Major Paediatric Referral hospitals reported demand lower than 2019 or occupancy lower than 2018. CONCLUSIONS: Occupancy increased by more than demand 2017-2019, with some decrease in 2020: in June presentations were 12.7% lower than 2019, in September back to the normal range outside Victorian and Major Paediatric Referral hospitals. Future research needs to consider locality, role delineation and work practice change in comparing ED pandemic responses.

Effects of a hospital-wide intervention on emergency department crowding and quality: A prospective study.

OBJECTIVE: The objective of this study was to determine the impact of a management-supported, multimodal, hospital-wide intervention on ED crowding and quality measures. METHODS: This is a prospective descriptive study of the first 20 weeks of the intervention, with 3 years of historical controls. The study was conducted in a 600 bed adult/paediatric tertiary hospital with 80 000 ED presentations annually. ED information system data were collected on all presentations in matched 20 week periods. Multiple interventions included ED Navigator role, ED Medical Staff teaming, corporate focus with key performance indicators and dashboards, appointment of a Director of Operations, Long Length of Stay Committee and reorganisation of the flow (bed management) unit. Process outcomes were 4 h performance as a proportion of all patients and mean daily length of crowding with more than 10 inpatients awaiting beds expressed as a time. Quality outcomes were proportions of patients who did not wait and who re-presented within 72 h. RESULTS: There was a 9.1% increase in presentations and a 22.6% decrease in mean ED occupancy over the previous year. The 4 h performance improved from 56.1% (95% confidence interval [CI] 55.5-56.7) to 68.8% (95% CI 68.3-69.3) and daily crowding with more than 10 inpatients improved from 6:34 (95% CI 5:32-7:37) to 0:29 (95% CI 0:15-0:42). Did not wait improved significantly from 5.1 to 3.0% and rate of representation did not change. CONCLUSION: This prospective study shows significant improvement in ED flow without compromise in quality measures from a hospital-wide intervention requiring minimal additional resources. Further research is required on sustainability and patient outcomes beyond the ED.

Perceptions of Australasian emergency department staff of the impact of alcohol-related presentations.

OBJECTIVES: To survey emergency department (ED) clinical staff about their perceptions of alcohol-related presentations. DESIGN, SETTING AND PARTICIPANTS: A mixed methods online survey of ED clinicians in Australia and New Zealand, conducted from 30 May to 7 July 2014. MAIN OUTCOME MEASURES: The frequency of aggression from alcohol-affected patients or their carers experienced by ED staff; the perceived impact of alcohol-related presentations on ED function, waiting times, other patients and staff. RESULTS: In total, 2002 ED clinical staff completed the survey, including 904 ED nurses (45.2%) and 1016 ED doctors (50.7%). Alcohol-related verbal aggression from patients had been experienced in the past 12 months by 97.9% of respondents, and physical aggression by 92.2%. ED nurses were the group most likely to have felt unsafe because of the behaviour of these patients (92% reported such feelings). Alcohol-related presentations were perceived to negatively or very negatively affect waiting times (noted by 85.5% of respondents), other patients in the waiting room (94.4%), and the care of other patients (88.3%). Alcohol-affected patients were perceived to have a negative or very negative impact on staff workload (94.2%), wellbeing (74.1%) and job satisfaction (80.9%). CONCLUSIONS: Verbal and physical aggression by alcohol-affected patients is commonly experienced by ED clinical staff. This has a negative impact on the care of other patients, as well as on staff wellbeing. Managers of health services must ensure a safe environment for staff and patients. More importantly, a comprehensive public health approach to changing the prevailing culture that tolerates alcohol-induced unacceptable behaviour is required.

Survey of alcohol-related presentations to Australasian emergency departments.

OBJECTIVE: To determine the proportion of alcohol-related presentations to emergency departments (EDs) in Australia and New Zealand, at a single time point on a weekend night shift. DESIGN, SETTING AND PARTICIPANTS: A point prevalence survey of ED patients either waiting to be seen or currently being seen conducted at 02:00 local time on 14 December 2013 in 106 EDs in Australia and New Zealand. MAIN OUTCOME MEASURES: The number of ED presentations that were alcohol-related, defined using World Health Organization ICD-10 codes. RESULTS: At the 106 hospitals (92 Australia, 14 New Zealand) that provided data, 395 (14.3%; 95% CI, 13.0%-15.6%) of 2766 patients in EDs at the study time were presenting for alcohol-related reasons; 13.8% (95% CI, 12.5%-15.2%) in Australia and 17.9% (95% CI, 13.9%-22.8%) in New Zealand. The distribution was skewed left, with proportions ranging from 0 to 50% and a median of 12.5%. Nine Australian hospitals and one New Zealand hospital reported that more than a third of their ED patients had alcohol-related presentations; the Northern Territory (38.1%) and Western Australia (21.1%) reported the highest proportions of alcohol-related presentations. CONCLUSIONS: One in seven ED presentations in Australian and New Zealand at this 02:00 snapshot were alcohol-related, with some EDs seeing more than one in three alcohol-related presentations. This confirms that alcohol-related presentations to EDs are currently underreported and makes a strong case for public health initiatives.

Access block and ED overcrowding.

Prospective and retrospective access block hospital intervention studies from 1998 to 2008 were reviewed to assess the evidence for interventions around access block and ED overcrowding, including over 220 documents reported in Medline and data extracted from The State of our Public Hospitals Reports. There is an estimated 20-30% increased mortality rate due to access block and ED overcrowding. The main causes are major increases in hospital admissions and ED presentations, with almost no increase in the capacity of hospitals to meet this demand. The rate of available beds in Australia reduced from 2.6 beds per 1000 (1998-1999) to 2.4 beds per 1000 (2002-2007) in 2002, and has remained steady at between 2.5-2.6 beds per 1000. In the same period, the number of ED visits increased over 77% from 3.8 million to 6.74 million. Similarly, the number of public hospital admissions increased at an average rate of 3.4% per year from 3.7 to 4.7 million. Compared with 1998-1999 rates, the number of available beds in 2006-2007 is thus similar (2.65 vs 2.6 beds per 1000), but the number of ED presentations has almost doubled. All patient groups are affected by access block. Access block interventions may temporarily reduce some of the symptoms of access block, but many measures are not sustainable. The root cause of the problem will remain unless hospital capacity is addressed in an integrated approach at both national and state levels.

Myths versus facts in emergency department overcrowding and hospital access block.

Overcrowding occurs when emergency department (ED) function is impeded, primarily by overwhelming of ED staff resources and physical capacity by excessive numbers of patients needing or receiving care. Access block occurs when there is excessive delay in access to appropriate inpatient beds (> 8 hours total time in the ED). Access block for admitted patients is the principal cause of overcrowding, and is mainly the result of a systemic lack of capacity throughout health systems, and not of inappropriate presentations by patients who should have attended a general practitioner. Overcrowding is most strongly associated with excessive numbers of admitted patients being kept in the ED. Excessive numbers of admitted patients in the ED are associated with diminished quality of care and poor patient outcomes. These include (but are not limited to) adverse events, errors, delayed time-critical care, increased morbidity and excess deaths (estimated as at least 1500 per annum in Australia). There is no evidence that telephone advice lines or collocated after-hours GP services assist in reducing ED workloads. Changes to ED structure and function do not address the underlying causes or major adverse effects of overcrowding. They are also rapidly overwhelmed by increasing access block. The causes of overcrowding, and hence the solutions, lie outside the ED. Solutions will mainly be found in managing hospital bedstock and systemic capacity (including the use of step-down and community resources) so that appropriate inpatient beds remain available for acutely sick patients.

Tackling the burden of injury in Australasia: developing a binational trauma registry.

Existing trauma registries in Australia and New Zealand play an important role in monitoring the management of injured patients. Over the past decade, such monitoring has been translated into changes in clinical processes and practices. Monitoring and changes have been ad hoc, as there are currently no Australasian benchmarks for "optimal" injury management. A binational trauma registry is urgently needed to benchmark injury management to improve outcomes for injured patients.

Increase in patient mortality at 10 days associated with emergency department overcrowding.

OBJECTIVE: To quantify any relationship between emergency department (ED) overcrowding and 10-day patient mortality. DESIGN AND SETTING: Retrospective stratified cohort analysis of three 48-week periods in a tertiary mixed ED in 2002-2004. Mean "occupancy" (a measure of overcrowding based on number of patients receiving treatment) was calculated for 8-hour shifts and for 12-week periods. The shifts of each type in the highest quartile of occupancy were classified as overcrowded. PARTICIPANTS: All presentations of patients (except those arriving by interstate ambulance) during "overcrowded" (OC) shifts and during an equivalent number of "not overcrowded" (NOC) shifts (same shift, weekday and period). MAIN OUTCOME MEASURE: In-hospital death of a patient recorded within 10 days of the most recent ED presentation. RESULTS: There were 34 377 OC and 32 231 NOC presentations (736 shifts each); the presenting patients were well matched for age and sex. Mean occupancy was 21.6 on OC shifts and 16.4 on NOC shifts. There were 144 deaths in the OC cohort and 101 in the NOC cohort (0.42% and 0.31%, respectively; P=0.025). The relative risk of death at 10 days was 1.34 (95% CI, 1.04-1.72). Subgroup analysis showed that, in the OC cohort, there were more presentations in more urgent triage categories, decreased treatment performance by standard measures, and a higher mortality rate by triage category. CONCLUSIONS: In this hospital, presentation during high ED occupancy was associated with increased in-hospital mortality at 10 days, after controlling for seasonal, shift, and day of the week effects. The magnitude of the effect is about 13 deaths per year. Further studies are warranted.

Emergency response to the Canberra bushfires.

On 18 January 2003, Canberra experienced major bushfires. Over 6 hours, The Canberra Hospital Emergency Department treated 139 patients, 105 with fire-related problems (mostly ophthalmological and respiratory), representing an additional workload of one patient every 4 minutes above average. Only 15% required hospital admission. We believe this is the largest single emergency department response to a disaster since Cyclone Tracy devastated Darwin in 1974, although the total severity of injury was relatively low. Major issues were communication difficulties and transport, with most patients (including the two most critically ill) arriving by private vehicle. Overall, medical outcomes were excellent, and the hospital system coped well.

The access-block effect: relationship between delay to reaching an inpatient bed and inpatient length of stay.

OBJECTIVES: To investigate the relationship between access block in the emergency department (ED) (defined as total time from arrival to transfer from the ED over eight hours) and inpatient length of stay (LOS). DESIGN AND SETTING: Retrospective cohort study of all admissions through the ED to a tertiary hospital in Canberra, Australian Capital Territory, during 1999. MAIN OUTCOME MEASURES: Total time in the ED and LOS, calculated in days from ED departure to hospital discharge (non-overnight admissions were assigned LOS of one day, and all LOS were truncated at 10 days). RESULTS: 11 906 admissions were included, and 919 experienced access block (7.7%). Mean LOS was 4.9 days in those who experienced access block (95% CI, 4.7-5.1), compared with 4.1 days in the no-block group (95% CI, 4.0-4.2; P < 0.0001). Subgroup analysis showed that this "access block effect" occurred across different severities of illness and diagnoses. A strong relationship was found between longer LOS and arrival of access-block patients on the inpatient ward outside office hours (0800-1600 weekdays). CONCLUSIONS: This is the first study to show an association between access block and a measure of outcome outside the ED. If the effect of access block on LOS is reproduced in other settings, there are major implications for hospital management.

A comparison of the antemortem clinical diagnosis and autopsy findings for patients who die in the emergency department.

OBJECTIVES: In spite of advances in medical technology, there remains a high discrepancy rate between the antemortem clinical diagnosis and postmortem examination diagnosis for patients who die in hospitals. The aim of this study was to compare the clinical and postmortem examination diagnoses of patients who died in the emergency department (ED) of a tertiary hospital, and to analyze any discrepancy between them. METHODS: The study was a retrospective chart review of patients who died in the ED of a tertiary referral teaching hospital and a comparison of the antemortem diagnosis with the autopsy diagnosis. Any missed diagnosis was classified, according to the Goldman criteria, into major and minor missed diagnoses. RESULTS: A total of 59 patients were eligible for inclusion in the study. There was complete agreement between the antemortem diagnosis and the autopsy result in 51% of cases. The incidence of major missed diagnoses-where if the diagnosis had been known before the patient died, treatment may have been altered or survival may have been prolonged-was 7%. CONCLUSIONS: There is a significant discrepancy rate between the antemortem diagnosis and the autopsy diagnosis. However, in this study, serious missed diagnoses in which outcome may have been significantly altered are unusual among those who die in the ED of a tertiary referral hospital.
