The epidemiology of dying within 48 hours of presentation to emergency departments: a retrospective cohort study of older people across Australia and New Zealand.

BACKGROUND: Emergency department (ED) clinicians are more frequently providing care, including end-of-life care, to older people. OBJECTIVES: To estimate the need for ED end-of-life care for people aged ≥65 years, describe characteristics of those dying within 48 hours of ED presentation and compare those dying in ED with those dying elsewhere. METHODS: We conducted a retrospective cohort study analysing data from 177 hospitals in Australia and New Zealand. Data on older people presenting to ED from January to December 2018, and those who died within 48 hours of ED presentation, were analysed using simple descriptive statistics and univariate logistic regression. RESULTS: From participating hospitals in Australia or New Zealand, 10,921 deaths in older people occurred. The 48-hour mortality rate was 6.43 per 1,000 ED presentations (95% confidence interval: 6.31-6.56). Just over a quarter (n = 3,067, 28.1%) died in ED. About one-quarter of the cohort (n = 2,887, 26.4%) was triaged into less urgent triage categories. Factors with an increased risk of dying in ED included age 65-74 years, ambulance arrival, most urgent triage categories, principal diagnosis of circulatory system disorder, and not identifying as an Aboriginal or Torres Strait Islander person. Of the 7,677 older people admitted, half (n = 3,836, 50.0%) had an encounter for palliative care prior to, or during, this presentation. CONCLUSIONS: Our findings provide insight into the challenges of recognising the dying older patient and differentiating those appropriate for end-of-life care. We support recommendations for national advanced care planning registers and suggest a review of triage systems with an older person-focused lens.

Mass Gathering Event Medical Preparedness and Response: A Review of Canadian Legislation and Guidelines.

INTRODUCTION: The mass gathering event (MGE) industry is growing globally, including in countries such as Canada. MGEs have been associated with a greater prevalence of injury and illness when compared with daily life events, despite most participants having few comorbidities. As such, adequate health, safety, and emergency medical planning is required. However, there is no single entity regulating these concerns for MGEs, resulting in the responsibility for health planning lying with event organizers. This study aims to compare the legislative requirements for MGE medical response systems in the 13 provinces and territories of Canada. METHODS: This study is a cross-sectional descriptive analysis of Canadian legislation. Lists of publicly available legislative requirements were obtained by means of the emergency medical services directors and Health Ministries. Descriptive statistics were performed to compare legislation. RESULTS: Of the 13 provinces and territories, 10 responded. For the missing 3, a law library review confirmed the absence of specific legislation. Most (n = 6; 60%) provinces and territories referred to provisions in their Public Health laws. Four confirmed that MGE medical response was a municipal or local concern to be addressed by the event organizers. CONCLUSIONS: No provinces could list specific legislation guiding safety, health, and medical response for an MGE.

The impact of COVID-19 on emergency department presentations for mental health disorders in Queensland, Australia: A time series analysis.

BACKGROUND: The COVID-19 pandemic has been associated with detrimental effects on mental health and psychological well-being. Although multiple studies have shown decreases in mental health-related Emergency Department (ED) presentations early in the COVID-19 pandemic, the medium-term effects on mental health-related ED presentations have remained less clear. This study aimed to evaluate the effect of the pandemic on mental health ED presentations by comparing observed presentation numbers to predictions from pre-pandemic data. METHODS: This retrospective cohort study tallied weekly ED presentations associated with mental health disorders from a state-wide minimum dataset. Three time periods were identified: Pre-Pandemic (January 1, 2018-March 8, 2020), Statewide Lockdown (March 9, 2020-June 28, 2020), and Restrictions Easing (June 29, 2020-June 27, 2021). Time series analysis was used to generate weekly presentation forecasts using pre-pandemic data. Observed presentation numbers were compared to these forecasts. RESULTS: Weekly presentation numbers were lower than predicted in 11 out of 16 weeks in the Statewide Lockdown period and 52 out of 52 weeks in the Restrictions Easing period. The largest decrease was seen for anxiety disorders (Statewide Lockdown: 76.8% of forecast; Restrictions Easing: 36.4% of forecast), while an increase was seen in presentations for eating disorders (Statewide Lockdown: 139.5% of forecast; Restrictions Easing: 194.4% of forecast). CONCLUSIONS: Overall weekly mental health-related presentations across Queensland public EDs were lower than expected for the first 16 months of the COVID-19 pandemic. These findings underline the limitations of emergency department provision of mental health care and the importance of alternate care modalities in the pandemic context.

Characteristics and outcomes of emergency department presentations brought in by police with and without an emergency examination authority: A state-wide cohort study.

BACKGROUND: The aim of this study was to describe and compare the demographic characteristics, clinical characteristics and patient and health service outcomes of emergency department (ED) presentations brought in by police with and without an emergency examination authority. METHODS: A retrospective cohort study of adult (≥ 18 years old) presentations brought in by police to EDs in Queensland, Australia from 01 January 2018 to 31 December 2020. Routinely collected ED data were used to describe and compare the demographic characteristics, clinical characteristics, and outcomes of people brought in by police with and without an emergency examination authority. RESULTS: A total of 42 502 adult ED presentations were brought in by police over the three-year period, of which 22 981 (44.7%) had an emergency examination authority. Compared with presentations brought in by police without an emergency examination authority, those brought in by police with an emergency examination authority had a higher proportion of presentations for mental health problems, were from major cities, and were allocated more urgent Australasian Triage Scale categories. Presentations brought in by police with an emergency examination authority were less likely to be seen within their Australasian Triage Scale timeframe and experienced a longer length of stay than those brought in by police without an emergency examination authority whether admitted (217 mins vs. 186 mins, p < 0.001) or discharged (212 mins vs. 97 mins, p < 0.001). CONCLUSIONS: The characteristics and outcomes of people brought in by police with emergency examination authorities differed to those brought in by police without emergency examination authorities. Further research is required to enhance understanding of this relatively unexplored group of people and foster interagency collaborations.

Providing end of life care in the emergency department: A hermeneutic phenomenological study.

BACKGROUND: Registered nurses report the experience of delivering end of life care in emergency departments as challenging. The study aim was to understand what it is like to be a registered nurse providing end of life care to an older person in the emergency department. METHODS: A hermeneutic phenomenological study was conducted in 2021, using semi-structured interviews with seven registered nurses across two hospital emergency departments in Queensland, Australia. Thematic analysis of participants' narratives was undertaken. FINDINGS: Seven registered nurses were interviewed; six of whom were women. Participant's experience working in the emergency department setting ranged from 2.5-20 years. Two themes were developed through analysis: (i) Presenting the patient as a dying person; and (ii) Mentalising death in the context of the emergency department. CONCLUSIONS: Nurses providing end of life care in the emergency department draw upon their personal and aesthetic knowing to present the dying patient as a person. The way death is mentalised suggests the need to develop empirical knowing about ageing and supportive medical care and ethical knowing to assist with the transition from resuscitation to end of life care. Shared clinical reflection on death in the emergency department, facilitated by experts in ageing and end of life care is recommended.

End-of-life care: A retrospective cohort study of older people who died within 48 hours of presentation to the emergency department.

OBJECTIVES: To describe the characteristics of, and care provided to, older people who died within 48 h of ED presentation. METHODS: A descriptive retrospective cohort study of people 65 years and older presenting to two EDs in Queensland, Australia, between April 2018 and March 2019. Data from electronic medical records were collected and analysed. RESULTS: Two hundred and ninety-five older people who died within 48 h of ED presentation were included. Nearly all arrived by ambulance (92%, n = 272) and 36% (n = 106) were from aged care facilities. Three-quarters (75%, n = 222) were triaged into the most urgent triage categories (i.e. Australasian Triage Scale; ATS 1/2). Fewer than half were previously independent with mobility (38%, n = 111) and activities of daily living (43%, n = 128). Sixty-one per cent (n = 181) had a pre-existing healthcare directive. Twenty-two per cent (n = 66) died in ED, most commonly due to pneumonia, intracerebral haemorrhage, cardiac arrest and/or sepsis. Over half had one or more ED visits (52%, n = 154) and/or hospital admissions (52%, n = 152) 6 months prior. CONCLUSIONS: Identification of patients at end-of-life (EoL) is not always straightforward; consider recent reduction in independence and recent ED visits/hospital admissions. System-based strategies that span pre-hospital, ED and in-patient care are recommended to facilitate EoL pathway implementation and care continuity.

Care in emergencies and disasters: Can it be person-centered?

OBJECTIVES: While person-/patient-centered care aims to influence policymakers' rules and regulations to improve the care of individuals worldwide, exploration of the concept in the context of disaster and public health emergencies as an alternative ethical approach is lacking. This study aims to provide a nuanced understanding of the advantages and challenges of diverse ethical approaches in emergencies, to improve patient care. METHODS: A survey, created after several rounds of Delphi methodology, with 22 statements, was applied to 39 participants from nine different countries. The questionnaire's results, including participants' comments, were analyzed. RESULTS: The results show that practitioners chose to use a combination of diverse ethical approaches in managing victims of disasters and public health emergencies. CONCLUSION: The selection of an approach is context- and situation-dependent and seems to primarily respond to the nature of underlying etiology, creating a possibility to use diverse approaches to offer individualized care on a later occasion and when a flexible surge capacity is available. PRACTICE IMPLICATIONS: The outcomes of this study will enhance the future ethical discussion in person/patient-centered care during situations with limited resources and help to develop necessary ethical and educational guidelines.

Clinicians' experiences of caring for people brought in by police to the emergency department: A qualitative interpretive study.

AIM: To explore nurses' and doctors' experiences of providing care to people brought in by police (BIBP) to the emergency department (ED). DESIGN: A qualitative interpretive study using in-depth individual interviews. METHODS: Semi-structured interviews were conducted with nurses and doctors who worked in various EDs in one Australian state and were involved in the care of people BIBP. Interviews were undertaken between May and October 2022 and focused on the structures (i.e., what), processes (i.e., how) and outcomes of care for people BIBP. Data were analysed using deductive and then inductive content analysis. RESULTS: Nine nurses and eight doctors were interviewed. Structures described by participants included human structures (staff) and organizational structures (areas for assessment, involuntary assessment orders, investigations, chemical/physical restraints). For processes, participants described practices including risk/mental health assessments, legal considerations, and increased/decreased levels of care compared to other presentations. Communication processes were largely between police and health care staff. Service outcomes pertained to discharge location (custody, community, hospital admission) and length of stay. CONCLUSION: The current care delivery for people BIBP to the ED is unique and complex, often occurring in high traffic, resource-intensive areas. There is a need to strengthen structures and processes, to improve service outcomes. IMPLICATIONS FOR THE PROFESSION: Understanding the care requirements for people brought into ED by police enables the delivery of targeted care alongside appropriate resource allocation. IMPACT: This study provides a comprehensive understanding of the health care requirements for people BIBP to EDs. Interventions delivered in the ED to support health care delivery for people BIBP and foster clinician and police relationships are required to optimize patient and health service outcomes. REPORTING METHOD: This study adheres to the COREQ checklist (Table S1) of the EQUATOR guidelines. PATIENT OR PUBLIC CONTRIBUTION: This study focused on ED staff experiences.

Review article: Scoping review of the characteristics and outcomes of adults presenting to the emergency department during heatwaves.

As a result of climate change heatwaves are expected to increase in frequency and intensity and will have detrimental impacts on human health globally. EDs are often the critical point of care for acute heat illnesses and other conditions associated with heat exposure. Existing literature has focused on heatwave-related hospitalisation and mortality. This scoping review aimed to identify, evaluate and summarise current literature regarding patient characteristics and outcomes of ED admissions from heatwaves. A scoping review of the literature was conducted using six databases: Medline, EMBASE, EMCARE, CINAHL, PsycINFO, and Scopus, using MeSH terms and keywords related to 'heatwave' and 'Emergency Department'. Articles were included if they were: published in English from January 2000 to August 2021, related to ED, and examined high temperature periods consistent with heatwave criteria. Articles were appraised using the Mixed Methods Appraisal Tool (MMAT). Thirty-one studies were included, mostly from the United States, Australia, and France. The study designs include retrospective case analysis, case-control, and time-series analysis. Eight studies examined known heatwaves, 21 used different criteria to identify heatwave occurrence, and two focused on heat-related illness. The selected articles display a moderate-high quality on MMAT. ED admissions for both heat-related illnesses and other conditions increased during heatwaves, with up to 18.5 times risk increase. The risk was elevated for all population groups, and substantially in the elderly, male patients with certain comorbidities, medications, or lower socioeconomic status. Outcomes including hospitalisation and mortality rates after ED admissions showed positive associations with heatwaves. The heatwaves resulting from climate change will place increasing demands on EDs providing care for increasingly susceptible populations. Significant public heatwave planning across multiple sectors is required to reduce the risk of overwhelming EDs with these patients.

Alcohol-Related Presentations to Emergency Departments on Days with Holidays, Social, and Sporting Events: An Integrative Literature Review.

INTRODUCTION: Events, specifically those where excessive alcohol consumption is common, pose a risk to increase alcohol-related presentations to emergency departments (EDs). Limited evidence exists that synthesizes the impact from events on alcohol-related presentations to EDs. STUDY OBJECTIVE: This integrative review aimed to synthesize the literature regarding the impact events have on alcohol-related presentations to EDs. METHODS: An integrative literature review methodology was guided by the Preferred Reporting Items of Systematic Reviews and Meta-Analysis (PRISMA) Guidelines for data collection, and Whittemore and Knafl's framework for data analysis. Information sources used to identify studies were MEDLINE, CINAHL, and EMBASE, last searched May 26, 2021. RESULTS: In total, 23 articles describing 46 events met criteria for inclusion. There was a noted increase in alcohol-related presentations to EDs from 27 events, decrease from eight events, and no change from 25 events. Public holidays, music festivals, and sporting events resulted in the majority of increased alcohol-related presentations to EDs. Few articles focused on ED length-of-stay (LOS), treatment, and disposition. CONCLUSION: An increase in the consumption of alcohol from holiday, social, and sporting events pose the risk for an influx of presentations to EDs and as a result may negatively impact departmental flow. Further research examining health service outcomes is required that considers the impact of events from a local, national, and global perspective.

Profile and Outcomes of Emergency Department Mental Health Patient Presentations Based on Arrival Mode: A State-Wide Retrospective Cohort Study.

INTRODUCTION: People arriving to the emergency department with mental health problems experience varying and sometimes inferior outcomes compared with people without mental health problems, yet little is known about whether or how their arrival mode is associated with these outcomes. This study describes and compares demographics, clinical characteristics, and patient and health service outcomes of adult mental health emergency department patient presentations, based on arrival mode: brought in by ambulance, privately arranged transport, and brought in by police. METHODS: Using a retrospective observational study design with state-wide administrative data from Queensland, Australia, mental health presentations from January 1, 2012, to December 31, 2017, were analyzed using descriptive and inferential analyses. RESULTS: Of the 446,815 presentations, 51.8% were brought in by ambulance, 37.2% arrived via privately arranged transport, and 11.0% were brought in by police. Compared with other arrival modes, presentations brought in by ambulance were more likely to be older and female and have more urgent triage categories and a longer length of stay. Presentations arriving by privately arranged transport were more likely than other arrival modes to present during the day, be assigned a less urgent triage category, be seen within their recommended triage time, have a shorter length of stay in the emergency department, have higher rates of discharge, and have waited longer to be seen by a clinician. Presentations brought in by police were more likely than other arrival modes to be younger and male and experience a shorter time to be seen by a clinician. DISCUSSION: Discrepancies between arrival modes indicates a need for further investigation to support inter- and intra-agency mental health care interventions.

Corrigendum to: Factors associated with emergency department service outcomes for people with a mental health problem brought in by police: a retrospective cohort study.

Objective This study aimed to identify factors associated with an emergency department (ED) length of stay ≥4 hours (h) and hospital admission for people with a mental health problem brought in by police. Methods We undertook a retrospective, observational cohort study of state-wide adult ED mental health presentations brought in by police from 1 January 2012 to 31 December 2017. We used multivariable logistic regression to determine factors associated with an ED length of stay ≥4 h and hospital admission. Results In total, 9325 ED presentations with a mental health problem brought in by police to Queensland EDs were included. Factors most strongly associated with an ED length of stay ≥4 h included an Australasian Triage Score (ATS) of 1, an age of 85 years or older, night shift arrival and subsequent hospital admission. For hospital admission, an ATS of 1, an age of 85 years or older and an ED length of stay ≥4 h were the strongest factors. Conclusion Findings indicate opportunities for targeted mental health models of care to better support people brought in by police to an ED. Such models should involve ED, pre-hospital providers (police and ambulance) and mental health services to support early intervention and potentially reduce the likelihood of a long ED length of stay and subsequent hospital admission.

Patient and public involvement in emergency care research: a scoping review of the literature.

BACKGROUND: Establishing the benefits of patient and public involvement (PPI) in emergency care research is important to improve the quality and relevance of research. Little is known about the extent of PPI in emergency care research, its methodological and reporting quality. This scoping review aimed to establish the extent of PPI in emergency care research, identify PPI strategies and processes and assess the quality of reporting on PPI in emergency care research. METHODS: Keyword searches of five databases (OVID MEDLINE, Elsevier EMBASE, EBSCO CINAHL, PsychInfo, Cochrane Central Register of Controlled trials); hand searches of 12 specialist journals and citation searches of the included journal articles were performed. A patient representative contributed to research design and co-authored this review. RESULTS: A total of 28 studies reporting PPI from the USA, Canada, UK, Australia and Ghana were included. The quality of reporting was variable, with only seven studies satisfying all Guidance for Reporting Involvement of Patients and the Public short form reporting criteria. None of the included studies adequately described all the key aspects of reporting the impact of PPI. CONCLUSION: Relatively few emergency care studies comprehensively describe PPI. Opportunity exists to improve the consistency and quality of reporting of PPI in emergency care research. Further research is required to better understand the specific challenges for implementing PPI in emergency care research, and to determine whether emergency care researchers have adequate resources, education and funding to undertake and report involvement.

Occupational violence in a tertiary emergency department: A retrospective descriptive study.

OBJECTIVE: Occupational violence in emergency departments (EDs) impacts staff and patients. Most hospitals have a response mechanism called a 'Code Black' or similar. We aimed to determine the incidence of Code Black activations in a tertiary ED and describe contributory factors, management strategies and adverse events. METHODS: Descriptive study in a tertiary ED in South-East Queensland in 2021. Adult patients for who a Code Black had been activated were eligible. Data were obtained from a prospectively collected Code Black database, supplemented with retrospective electronic medical records. RESULTS: There were 386 Code Black events. The incidence of Code Black activation was 11.0 per 1000 adult ED presentations. Individuals requiring Code Black activation were 59.6 % male with a mean age of 40.9 years. The primary diagnosis was mental illness related in 55.1 %. Alcohol was a suspected factor in 30.9 %. When Code Black activation occurred, median length of stay increased. Restraint including physical, chemical or both were used in 54.1 % of Code Blacks. CONCLUSION: Occupational violence occurs at a three-fold greater incidence within this ED than reported elsewhere. This study reinforces other literature suggesting an increase in occupational violence, demonstrating the need for dedicated preventative strategies for patients at risk of agitation.

People brought to the emergency department under involuntary assessment orders: A scoping review.

BACKGROUND: Some people with mental health problems arrive to the Emergency Department (ED) under involuntary assessment orders (IAOs) and can have complex medical and socioeconomic factors, which may impact on the delivery of care in the ED. Therefore, this scoping review aimed to identify, evaluate and summarise the current literature regarding the demographic characteristics, clinical characteristics and outcomes for people brought to the ED under IAOs. METHOD: A scoping review was undertaken guided by the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) Guidelines and the Arksey and O'Malley framework. RESULTS: In total 21 articles were included in this review. People under IAOs most commonly present to EDs with suicidal ideation/intent, with interagency involvement noted when responding to these people in the pre-hospital setting. Most people arriving to ED under IAOs were reported to experience length of staylonger than four hours. CONCLUSION: This review highlights the limited information pertaining to people brought to EDs under an IAO. High levels of mental health problems and extended length of stay for people under IAOs suggests the need for interagency collaboration to inform the development and implementation of models of care that incorporates social determinants of health and are tailored to this complex population.

Factors associated with emergency department service outcomes for people with a mental health problem brought in by police: a retrospective cohort study.

Objective This study aimed to identify factors associated with an emergency department (ED) length of stay ≥4 hours (h) and hospital admission for people with a mental health problem brought in by police. Methods We undertook a retrospective, observational cohort study of state-wide adult ED mental health presentations brought in by police from 1 January 2012 to 31 December 2017. We used multivariable logistic regression to determine factors associated with an ED length of stay ≥4 h and hospital admission. Results In total, 9325 ED presentations with a mental health problem brought in by police to Queensland EDs were included. Factors most strongly associated with an ED length of stay ≥4 h included an Australasian Triage Score (ATS) of 1, an age of 85 years or older, night shift arrival and subsequent hospital admission. For hospital admission, an ATS of 1, an age of 85 years or older and an ED length of stay ≥4 h were the strongest factors. Conclusion Findings indicate opportunities for targeted mental health models of care to better support people brought in by police to an ED. Such models should involve ED, pre-hospital providers (police and ambulance) and mental health services to support early intervention and potentially reduce the likelihood of a long ED length of stay and subsequent hospital admission.

Characteristics and outcomes of patient presentations to the emergency department via police: A scoping review.

BACKGROUND: As emergency department (ED) presentations continue to rise, understanding the complexities of vulnerable populations such as people brought in by police (BIBP) is crucial. This review aimed to map and describe the research about people BIBP to the ED. DESIGN AND METHOD: A scoping review, guided by the Joanna Briggs Institute process, was undertaken. The databases CINAHL, Embase and PubMed were searched between November 2017 and July 2022. The Patterns, Advances, Gaps, Evidence for practice, Research recommendations (PAGER) framework was used to guide the analysis. RESULTS: A total of 21 studies were included in the review, originating mainly from westernised countries. Examination of patterns across studies revealed four themes: routinely collected data is used to describe people BIBP to the ED; a focus on mental health care; the relationship between care delivery and outcomes; and the role of police in providing emergency care. CONCLUSION: There is some understanding of the demographic characteristics, clinical characteristics, and outcomes of people BIBP to the ED. Knowledge gaps surrounding sociodemographic factors, prehospital and ED care delivery for people BIBP require further investigation to optimise outcomes for this vulnerable cohort of presenters.

Enabling Transformational Leadership to Foster Disaster-Resilient Hospitals.

Hospitals' operational performance during disasters varies from failing, to being responsive and resilient, to dealing with disruption and surprise. Transformational leaders enable continuously learning hospitals that are resilient in the face of disasters by adapting regeneratively and evolving beyond undertaking conventional lesson-learning after each disaster. However, learning from successful transformational leaders in healthcare is still ad hoc with a lack of guidance on how to develop such leaders. Hence, this study sought to identify key competencies of transformational leaders by exploring hospital leaders' actions in dealing with disasters, considering the disaster cycle of prevention, preparedness, response, and recovery (PPRR). A qualitative case-study design was adopted comprising in-depth semi-structured interviews with twelve senior hospital staff with operational leadership experience with disasters. Three significant categories (themes) and seven key component competencies (sub-themes, in brackets) of transformational leaders were revealed through the analysis of transcripts: (1) 'Governance and leadership' ('transformative agency' and 'decisive accountability'); (2) 'Planning and risk assessment' ('risk navigation', 'disaster attunement', and 'planning agility'); and (3) 'Communication and network engagement' ('communication accelerator' and 'collaboration innovator'). The authors propose a transformational leadership model for hospital disaster resilience and an assessment checklist for leaders' self-reflection to support hospitals in their transition to resilient operations.

Emergency department presentations during the COVID-19 pandemic in Queensland (to June 2021): interrupted time series analysis.

OBJECTIVES: To assess emergency department (ED) presentation numbers in Queensland during the coronavirus disease 2019 (COVID-19) pandemic to mid-2021, a period of relatively low COVID-19 case numbers. DESIGN: Interrupted time series analysis. SETTING: All 105 Queensland public hospital EDs. MAIN OUTCOME MEASURES: Numbers of ED presentations during the COVID-19 lockdown period (11 March 2020 - 30 June 2020) and the period of easing restrictions (1 July 2020 - 30 June 2021), compared with pre-pandemic period (1 January 2018 - 10 March 2020), overall (daily numbers) and by Australasian Triage Scale (ATS; daily numbers) and selected diagnostic categories (cardiac, respiratory, mental health, injury-related conditions) and conditions (stroke, sepsis) (weekly numbers). RESULTS: During the lockdown period, the mean number of ED presentations was 19.4% lower (95% confidence interval, -20.9% to -17.9%) than during the pre-pandemic period (predicted mean number: 5935; actual number: 4786 presentations). The magnitudes of the decline and the time to return to predicted levels varied by ATS category and diagnostic group; changes in presentation numbers were least marked for ATS 1 and 2 (most urgent) presentations, and for presentations with cardiac conditions or stroke. Numbers remained below predicted levels during the 12-month post-lockdown period for ATS 5 (least urgent) presentations and presentations with mental health problems, respiratory conditions, or sepsis. CONCLUSIONS: The COVID-19 pandemic and related public restrictions were associated with profound changes in health care use. Pandemic plans should include advice about continuing to seek care for serious health conditions and health emergencies, and support alternative sources of care for less urgent health care needs.
