Strengthening emergency department response to chemical, biological, radiological, and nuclear disasters: A scoping review.

INTRODUCTION: Natural hazards resulting in disasters are increasing globally, impacting communities and disrupting industries. In addition to planning for these natural hazard disasters, emergency departments (EDs) should prepare for chemical, biological, radiological, and nuclear (CBRN) incidents that result in surges of patient presentations. Chemical, biological, radiological, and nuclear incidents differ in preparedness to natural hazards, requiring an understanding of patient management and health system-related challenges. METHODS: This scoping review used the Arksey and O'Malley five-step framework. Manuscripts were retrieved from four databases and search engines using keywords relating to impacts on the ED from real world CBRN event(s). Analysis focused on the characteristics of CBRN event, ED impact, and lessons learnt against four surge capacity domains that including staff, stuff, space, and systems. RESULTS: A total of 44 paper were included in this review. Most of the incidents were chemical in nature (n = 36/44, 81.8 %). The majority of CBRN incidents were accidental (n = 34/44, 77.3 %). Between 1 and 1470 people (Mdn=56, IQR: 18-228) presented to an ED from each event. Most patients were discharged from the ED, but this was variably reported. Some key lessons related to secondary exposure to ED staff, repurposing spaces, and coordination of CBRN incidents. CONCLUSION: With the increasing number of CBRN incidents, strategies to strengthen EDs and limit the impact from a surge in patient presentations are paramount. An understanding of local CBRN risk to inform a top-hazards approach to CBRN preparedness, and the implementation of pre-emptive CBRN clinical pathways is recommended. Additionally, strategies should be implemented to protect staff from the risk of secondary exposure to a CBRN event. These strategies may include adequate education, training, and personal protective equipment for staff.

An Evidence Gap Map of Experience-based Evidence of Health Resource Allocation in Disaster and Humanitarian Settings.

OBJECTIVE: The aim of this review is to identify, evaluate, and graphically display gaps in the literature related to scarce health resource allocation in humanitarian aid settings. METHODS: A systematic search strategy was utilized in MEDLINE (via Ovid), Scopus, EMBASE, CINAHL Complete, and ProQuest Central. Articles were reviewed by 2 reviewers with a third reviewer remedying any screening conflicts. Articles meeting inclusion criteria underwent data extraction to facilitate evaluation of the scope, nature, and quality of experience-based evidence for health resource allocation in humanitarian settings. Finally, articles were mapped on a matrix to display evidence graphically. RESULTS: The search strategy identified 6093 individual sources, leaving 4000 for screening after removal of duplicates. Following full-text screening, 12 sources were included. Mapping extracted data according to surge capacity domains demonstrated that all 4 domains were reflected most of all the staff domain. Much of the identified data was presented without adhering to a clear structure or nomenclature. Finally, the mapping suggested potential incompleteness of surge capacity constructs in humanitarian response settings. CONCLUSIONS: Through this review, we identified a gap in evidence available to address challenges associated with scarce resource allocation in humanitarian settings. In addition to presenting the distribution of existing literature, the review demonstrated the relevance of surge capacity and resource allocation principles underpinning the developed framework.

A Scoping Review of Trauma, Mental Health and First Responders in Australia.

Exposure to traumatic and/or violent events is an inherent part of the first responder role, which increases the risk of developing acute and chronic mental health symptoms and conditions. Suicidality for Australian first responders have recently increased with prevalence considered much higher compared with the general population. To inform specific recommendations for Australian first responders, there is a need to establish what evidence is available regarding these issues within the Australian context. The aim of this scoping review was to explore the impacts of trauma on the mental health of Australian first responders, the strategies recommended to address these issues and any unique needs in rural contexts. A scoping review was undertaken following PRISMA guidelines for scoping reviews. Peer-reviewed articles on Australian first responder mental health from seven databases were screened for inclusion. This review highlights that despite available evidence on the types of traumas and adverse mental health outcomes experienced, less evidence exists pertaining to intervention effectiveness. There are major gaps in evidence within rural and remote contexts which hinders effective planning and delivery of support for rural and regional first responders. Clinicians such as mental health nurses, particularly in rural areas, need to be aware of these gaps which impact planning and delivery of support and are in prime position to ensure screening, interventions and strategies are used and evaluated to determine their suitability for rural first responders.

Seasons of smoke and fire: preparing health systems for improved performance before, during, and after wildfires.

Increased frequency, intensity, and duration of wildfires are intensifying exposure to direct and smoke-related hazards in many areas, leading to evacuation and smoke-related effects on health and health systems that can affect regions extending over thousands of kilometres. Effective preparation and response are currently hampered by inadequate training, continued siloing of disciplines, insufficient finance, and inadequate coordination between health systems and governance at municipal, regional, national, and international levels. This Review highlights the key health and health systems considerations before, during, and after wildfires, and outlines how a health system should respond to optimise population health outcomes now and into the future. The focus is on the implications of wildfires for air quality, mental health, and emergency management, with elements of international policy and finance also addressed. We discuss commonalities of existing climate-resilient health care and disaster management frameworks and integrate them into an approach that addresses issues of financing, leadership and governance, health workforce, health information systems, infrastructure, supply chain, technologies, community interaction and health-care delivery, before, during, and after a wildfire season. This Review is a practical briefing for leaders and health professionals facing severe wildfire seasons and a call to break down silos and join with other disciplines to proactively plan for and fund innovation and coordination in service of a healthier future.

The Impact of Alcohol-Related Presentations to Emergency Departments on Days with a Public Holiday or Sporting Event: A Retrospective Cohort Study.

INTRODUCTION: The consumption of alcohol within the Australian community continues to rise, impacting care delivery in already over-burdened emergency departments (EDs). STUDY OBJECTIVE: This study aimed to examine the impact of alcohol-related presentations (ARPs) to EDs on days with a public holiday or sporting event. METHODS: A retrospective cohort study was undertaken using routinely collected health data pertaining to patient presentations diagnosed with an alcohol-related disorder (ICD-10-AM code F10) to two EDs in Queensland, Australia from January 1, 2016 - December 31, 2020. Descriptive and inferential statistics were used to describe and compare ARPs on event days versus non-event days and uncomplicated versus other ARPs on event days only. RESULTS: Of all 5,792 ARPs, nine percent (n = 529) occurred on public holidays or sporting event days. When compared by day type, type of presentation, mode of arrival, and day of week differed between event and non-event days. On event days, uncomplicated ARPs differed to other ARPs, with uncomplicated ARPs being younger, having shorter median length-of-stay (LOS), and less likely to be admitted to hospital. CONCLUSIONS: In this multi-site study, public holidays and sporting events had a noteworthy impact on ARPs to EDs. Focused refinement on the clinical management of uncomplicated ARPs is warranted to inform future resource allocation, including on event days.

Follow-up after major traumatic injury: a survey of services in Australian and New Zealand public hospitals.

BACKGROUND: Increased survival from traumatic injury has led to a higher demand for follow-up care when patients are discharged from hospital. It is currently unclear how follow-up care following major trauma is provided to patients, and how, when, and to whom follow-up services are delivered. The aim of this study was to describe the current follow-up care provided to patients and their families who have experienced major traumatic injury in Australia and New Zealand (ANZ). METHODS: Informed by Donabedian's 'Evaluating the Quality of Medical Care' model and the Institute of Medicine's Six Domains of Healthcare Quality, a cross-sectional online survey was developed in conjunction with trauma experts. Their responses informed the final survey which was distributed to key personnel in 71 hospitals in Australia and New Zealand that (i) delivered trauma care to patients, (ii) provided data to the Australasian Trauma Registry, or (iii) were a Trauma Centre. RESULTS: Data were received from 38/71 (53.5%) hospitals. Most were Level 1 trauma centres (n = 23, 60.5%); 76% (n = 16) follow-up services were permanently funded. Follow-up services were led by a range of health professionals with over 60% (n = 19) identifying as trauma specialists. Patient inclusion criteria varied; only one service allowed self-referral (3.3%). Follow-up was within two weeks of acute care discharge in 53% (n = 16) of services. Care activities focused on physical health; psychosocial assessments were the least common. Most services provided care for adults and paediatric trauma (60.5%, n = 23); no service incorporated follow-up for family members. Evaluation of follow-up care was largely as part of a health service initiative; only three sites stated evaluation was specific to trauma follow-up. CONCLUSION: Follow-up care is provided by trauma specialists and predominantly focuses on the physical health of the patients affected by major traumatic injury. Variations exist in terms of patient selection, reason for follow-up and care activities delivered with gaps in the provision of psychosocial and family health services identified. Currently, evaluation of trauma follow-up care is limited, indicating a need for further development to ensure that the care delivered is safe, effective and beneficial to patients, families and healthcare organisations.

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.

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.

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.

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.

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.

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.

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.
