Using emergency department data to define a 'mental health presentation' - implications of different definitions on estimates of emergency department mental health workload

Objective This study aimed to describe and compare the proportion of patients classified as an emergency department (ED) mental health presentation under different definitions, including the Australian Institute of Health and Welfare (AIHW) definition. Methods This retrospective cohort study enrolled all patients that presented to the EDs of a multi-centre Victorian health service between 1 January 2020 and 30 June 2023. Varying definitions of a mental health presentation were applied to each ED attendance, applying the current AIHW definition (using selected diagnosis codes), broader diagnosis-based coding, the presenting complaint recorded at triage and whether the patient was seen by or referred to the emergency psychiatric service (EPS). The proportion of all ED presentations meeting each definition and any overlap between definitions were calculated. The agreement between each definition and the AIHW definition was evaluated using Kappa's coefficient. Results There were 813,078 presentations to ED of which 34,248 (4.2%) met the AIHW definition for a mental health presentation. Throughout the study, 45,376 (5.6%) patients were seen and/or referred to EPS, and 36,160 (4.4%) patients were allocated a mental health presenting complaint by triage staff. There was moderate interrater agreement between these definitions, with a kappa statistic (95% confidence interval) between the AIHW definition and a mental health presenting complaint recorded at triage of 0.58 (0.58-0.59) and between the AIHW definition and review by EPS of 0.58 (0.57-0.58). Conclusions The AIHW definition is a conservative measure of ED mental health presentations and may underestimate emergency psychiatry workload in Australian EDs.

Emergency nurses' perspectives on mental health boarders: An integrative review

This integrative review is on emergency department nurses' perceptions on mental health patients waiting for placement. Seven articles met inclusion criteria. Themes included violence and patient safety, psychiatry and mental health support, attitudes and beliefs, education and training, emergency department workflow and environment, and long waits in the emergency department. Future research focusing on the care of mental health patients boarding in the emergency department is needed to address this issue. A limitation was that there were no focused studies on mental health boarders in the emergency department, and information had to be gleaned from articles on caring for mental health patients in emergency departments in general.

The epidemiology of acute pancreatitis in Tasmania over a 12-year period: Is this a disease of disadvantage?

BACKGROUND

The global incidence of acute pancreatitis (AP) is increasing, but little information exists about trends in Australia. This study aimed to describe incidence trends, along with clinical and socio-demographic associations, in the state of Tasmania over a recent 12-year period.

METHODS

The study cohort was obtained by linking clinical and administrative datasets encompassing the whole Tasmanian population between 2007 and 2018, inclusive. Pancreatitis case definition was based on relevant ICD-10 hospitalization codes, or elevated serum lipase or amylase in pathology data. Age-standardised incidence rates were estimated, overall and stratified by sex, aetiology, and Index of Relative Socio-economic Disadvantage (IRSD).

RESULTS

In the study period, 4905 public hospital AP episodes were identified in 3503 people. The age-standardised person-based incidence rate across the entire period was 54 per 100,000 per year. Incidence was inversely related to IRSD score; 71 per 100,000 per year in the most disadvantaged quartile compared to 32 in the least disadvantaged. Biliary AP incidence was higher than that of alcohol-related AP, although the greatest incidence was in "unspecified" cases. There was an increase in incidence for the whole cohort (average annual percent change 3.23 %), largely driven by the two most disadvantaged IRSD quartiles; the least disadvantaged quartile saw a slight overall decrease.

CONCLUSION

This is the first Australian study providing robust evidence that AP incidence is increasing and is at the upper limit of population-based studies worldwide. This increased incidence is greatest in socio-economically disadvantaged areas, meriting further research to develop targeted, holistic management strategies.

Exploring the lived experience of receiving mental health crisis care at emergency departments, crisis phone lines and crisis care alternatives

BACKGROUND

Mental health crisis care includes emergency departments (EDs), crisis phone lines and crisis alternatives. Currently, there is an overreliance on EDs to provide mental health crisis care, with evidence that responses are often inadequate to meet the needs of people experiencing mental health crises. However, the complexities of how individuals experience crisis care across the varying contexts of EDs, crisis phone lines and crisis alternatives remain underresearched.

METHOD

This study used a hermeneutical phenomenological approach to understand the lived experience of accessing care during a mental health crisis. Thirty-one Australian adults who had accessed crisis services at ED, phone lines and/or crisis alternatives participated in in-depth interviews.

RESULTS

The findings are organised across the temporal narratives of participants' experiences from (1) point of contact, (2) positive and negative care experiences and (3) enduring impacts. Several themes were generated during these phases. The findings demonstrate the interrelated nature of care experiences and enduring impacts. With some exceptions, care received within EDs was harmful, resulting in lasting adverse effects. Responses from crisis phone lines were mixed, with participants appreciating the accessibility of after-hour phone support but finding standardised risk assessments unhelpful. Responses from crisis alternatives to ED were promising, aligning with the need for validation and human connection, but were not always accessible or easy to mobilise during a crisis. Notably, across all settings, positive effects were firmly attributed to the quality of the relationship with specific crisis providers.

CONCLUSION

The findings bring into sharp focus the lived experience of people accessing crisis care and contribute to the shortage of literature on subjective experiences. Providers may better meet the needs of those experiencing mental health crises by understanding the enduring impact of these interactions and the role of human connection beyond a focus on risk assessment, thereby providing opportunities for a joint understanding of risk and meaning-making. Furthermore, understanding the subjective experience of crisis care can guide reforms to ED and develop crisis alternatives to better meet the needs of people in crisis.

The effect of psychiatric decision unit services on inpatient admissions and mental health presentations in emergency departments: an interrupted time series analysis from two cities and one rural area in England

AIMS

High-quality evidence is lacking for the impact on healthcare utilisation of short-stay alternatives to psychiatric inpatient services for people experiencing acute and/or complex mental health crises (known in England as psychiatric decision units [PDUs]). We assessed the extent to which changes in psychiatric hospital and emergency department (ED) activity were explained by implementation of PDUs in England using a quasi-experimental approach.

METHODS

We conducted an interrupted time series (ITS) analysis of weekly aggregated data pre- and post-PDU implementation in one rural and two urban sites using segmented regression, adjusting for temporal and seasonal trends. Primary outcomes were changes in the number of voluntary inpatient admissions to (acute) adult psychiatric wards and number of ED adult mental health-related attendances in the 24 months post-PDU implementation compared to that in the 24 months pre-PDU implementation.

RESULTS

The two PDUs (one urban and one rural) with longer (average) stays and high staff-to-patient ratios observed post-PDU decreases in the pattern of weekly voluntary psychiatric admissions relative to pre-PDU trend (Rural: -0.45%/week, 95% confidence interval [CI] = -0.78%, -0.12%; Urban: -0.49%/week, 95% CI = -0.73%, -0.25%); PDU implementation in each was associated with an estimated 35-38% reduction in total voluntary admissions in the post-PDU period. The (urban) PDU with the highest throughput, lowest staff-to-patient ratio and shortest average stay observed a 20% (-20.4%, CI = -29.7%, -10.0%) level reduction in mental health-related ED attendances post-PDU, although there was little impact on long-term trend. Pooled analyses across sites indicated a significant reduction in the number of voluntary admissions following PDU implementation (-16.6%, 95% CI = -23.9%, -8.5%) but no significant (long-term) trend change (-0.20%/week, 95% CI = -0.74%, 0.34%) and no short- (-2.8%, 95% CI = -19.3%, 17.0%) or long-term (0.08%/week, 95% CI = -0.13, 0.28%) effects on mental health-related ED attendances. Findings were largely unchanged in secondary (ITS) analyses that considered the introduction of other service initiatives in the study period.

CONCLUSIONS

The introduction of PDUs was associated with an immediate reduction of voluntary psychiatric inpatient admissions. The extent to which PDUs change long-term trends of voluntary psychiatric admissions or impact on psychiatric presentations at ED may be linked to their configuration. PDUs with a large capacity, short length of stay and low staff-to-patient ratio can positively impact ED mental health presentations, while PDUs with longer length of stay and higher staff-to-patient ratios have potential to reduce voluntary psychiatric admissions over an extended period. Taken as a whole, our analyses suggest that when establishing a PDU, consideration of the primary crisis-care need that underlies the creation of the unit is key.

Mapping clinical interactions in an Australian tertiary hospital emergency department for patients presenting with risk of suicide or self-harm: Network modeling from observational data

BACKGROUND

Reliable assessment of suicide and self-harm risk in emergency medicine is critical for effective intervention and treatment of patients affected by mental health disorders. Teams of clinicians face the challenge of rapidly integrating medical history, wide-ranging psychosocial factors, and real-time patient observations to inform diagnosis, treatment, and referral decisions. Patient outcomes therefore depend on the reliable flow of information through networks of clinical staff and information systems. This study aimed to develop a quantitative data-driven research framework for the analysis of information flow in emergency healthcare settings to evaluate clinical practice and operational models for emergency psychiatric care.

METHODS AND FINDINGS

We deployed 2 observers in a tertiary hospital emergency department during 2018 for a total of 118.5 h to record clinical interactions along patient trajectories for presentations with risk of self-harm or suicide (n = 272 interactions for n = 43 patient trajectories). The study population was reflective of a naturalistic sample of patients presenting to a tertiary emergency department in a metropolitan Australian city. Using the observational data, we constructed a clinical interaction network to model the flow of clinical information at a systems level. Community detection via modularity maximization revealed communities in the network closely aligned with the underlying clinical team structure. The Psychiatric Liaison Nurse (PLN) was identified as the most important agent in the network as quantified by node degree, closeness centrality, and betweenness centrality. Betweenness centrality of the PLN was significantly higher than expected by chance (>95th percentile compared with randomly shuffled networks) and removing the PLN from the network reduced both the global efficiency of the model and the closeness centrality of all doctors. This indicated a potential vulnerability in the system that could negatively impact patient care if the function of the PLN was compromised. We developed an algorithmic strategy to mitigate this risk by targeted strengthening of links between clinical teams using greedy cumulative addition of network edges in the model. Finally, we identified specific interactions along patient trajectories which were most likely to precipitate a psychiatric referral using a machine learning model trained on features from dynamically constructed clinical interaction networks. The main limitation of this study is the use of nonclinical information only (i.e., modeling is based on timing of interactions and agents involved, but not the content or quantity of information transferred during interactions).

CONCLUSIONS

This study demonstrates a data-driven research framework, new to the best of our knowledge, to assess and reinforce important information pathways that guide clinical decision processes and provide complementary insights for improving clinical practice and operational models in emergency medicine for patients at risk of suicide or self-harm. Our findings suggest that PLNs can play a crucial role in clinical communication, but overreliance on PLNs may pose risks to reliable information flow. Operational models that utilize PLNs may be made more robust to these risks by improving interdisciplinary communication between doctors. Our research framework could also be applied more broadly to investigate service delivery in different healthcare settings or for other medical specialties, patient groups, or demographics.

Sociodemographic characteristics and clinical outcomes for people presenting to emergency departments with mental health diagnoses

BACKGROUND

Hospital emergency departments (EDs) are experiencing a growth in presentations with mental health (MH) diagnoses.

AIM

Describe and compare sociodemographic characteristics and clinical outcomes for people with MH and non-MH diagnoses.

METHODS

A retrospective study examined routinely collected data for ED presentations in a health district in western Sydney, Australia from 2016 to 2019. Regression models examined variables according to MH status, overall and by age.

RESULTS

Individuals with MH diagnoses accounted for 3.4% of 647,787 ED presentations. MH presentations were most commonly female (51.5%), aged 16-39 years (62.5%), arrived after hours (60.3%) and via ambulance (52.8%). MH presentations were more likely to be triaged category 2 (OR = 1.58,95%CI = 1.54-1.63) and not seen on time (OR = 1.20,95%CI = 1.17-1.24). They had higher odds of a longer ED stay (OR = 1.96,95%CI = 1.90-20.1), after which they were less likely to be admitted (OR = 0.56, 95%CI = 0.55-0.58) and more likely to be transferred (OR = 3.81,95%CI = 3.66-3.97) or leave before treatment was completed (OR = 1.83,95%CI = 1.74-1.92).

CONCLUSION

Characteristics and outcomes for people presenting to ED with a MH diagnosis significantly differ from those without a MH diagnosis. Provision of timely care is a particular concern. Identifying causes for delays within and external to the ED, and implementing targeted strategies to ameliorate them are required to optimise care.

Patients languishing in emergency departments: A descriptive analysis of mental health-related emergency department presentations in Australia between 2016-17 and 2020-21

OBJECTIVE

In the context of concerns regarding hospital access block, this paper provides a descriptive longitudinal analysis of mental health-related ED episodes in Australian public hospitals between 2016-17 and 2020-21.

METHOD

We descriptively analysed Australian Institute of Health and Welfare data for mental health-related ED presentations, outcomes and 5-year trends for Australian public hospitals.

RESULTS

There were more than 300,000 Australian mental health-related ED presentations in 2020-21. Presentations increased by an average annual rate of 2.8% between 2016-17 and 2020-21, commonly involving first responder (police, paramedic) attendance. From 2016-17 to 2020-21, the average annual rate of mental health-related ED presentations receiving a triage category of resuscitation increased by 13.7%, emergency by 9.4% and urgent by 4.7%. 90% of MH-related ED presentations were completed within 14 h, which was longer than the 90th percentile for all ED presentations (up to 8 h).

CONCLUSIONS

Current mental health policies have not stemmed the rising tide of ED presentations. Mental health-related ED presentations are increasing in number and severity, likely due to health systemic and societal factors. Psychiatry patients stay longer in EDs than other patients. Healthcare reforms should be targeted to provide the best outcome based on principles of equity of access.

Mental health emergency presentations across the Barwon South West region in Victoria, Australia: An epidemiological investigation

OBJECTIVE

To examine mental health emergency presentations across the Barwon South West, Victoria, Australia - an area comprising a range of urban and rural localities.

METHODS

This is a retrospective synthesis of mental health emergency presentations across the Barwon South West (1 February 2017-31 December 2019). De-identified data were obtained from individuals who presented to EDs and urgent care centres (UCCs) within the study region, who had a principal diagnosis of a Mental and Behavioural Disorder (codes F00-F99). Data were sourced from the Victorian Emergency Minimum Dataset and Rural Acute Hospital Database Register (RAHDaR). Age-standardised incident rates for mental health emergency presentations were calculated for the whole sample and for local government areas. Data on usual accommodation, arrival transport mode, referral source, patient disposition and length of ED/UCC stay were also obtained.

RESULTS

We identified 11 613 mental health emergency presentations, with neurotic, stress-related and somatoform disorders (n = 3139, 27.0%) and mental and behavioural disorders due to psychoactive substance use (n = 3487, 30.0%) being the most frequent types of presentations recorded. The highest age-standardised incidence rates (mental health diagnosis per 1000 population/year) were in Glenelg (13.95), whereas Queenscliffe had the lowest incident rates (3.76). Most presentations (n = 3851, 33.2%) tended to occur for individuals aged between 15 and 29 years.

CONCLUSIONS

Neurotic, stress-related and somatoform disorders and mental and behavioural disorders due to psychoactive substance use were the most frequent types of presentations recorded across the sample. RAHDaR represented a small but meaningful contribution to the data.

Interventions to Reduce Repeat Presentations to Hospital Emergency Departments for Mental Health Concerns: A Scoping Review of the Literature

BACKGROUND

The number of readmissions to the emergency department (ED) for mental health services each year is significant, which increases healthcare costs and negatively affects the morale and quality of life of patients and their families.

OBJECT

This scoping review aimed to establish a better understanding of interventions that have been implemented to reduce psychiatric patient readmission and ED use within the ED, to identify areas for improvement, and therefore to assist in the development of more effective actions in the future.

METHOD

The scoping review was conducted on several bibliographic databases to identify relevant studies. Two researchers independently screened and reviewed titles, abstracts, and full-text articles that met the inclusion criteria. Using Covidence software, 26 out of 6951 studies were eligible for inclusion in this scoping review based on the PRISMA checklist. Data were extracted, collated, summarized, presented, and discussed.

RESULT

This review identified 26 studies which examined interventions aimed to reduce ED visits, such as the High Alert Program (HAP), the Patient-Centered Medical Home (PCMH), the Primary Behavioral Health Care Integration (PBHCI), and the Collaborative Care (CC) Program, etc. Twenty-three of the studies were conducted in North America, while the rest were conducted in Europe and Australia. A total of 16 studies examined interventions directed to any mental health conditions, while the rest addressed specific health conditions, such as substance use disorders, schizophrenia, anxiety, depression. Interventions involved comprehensive and multidisciplinary services, incorporation of evidence-based behavioral and pharmacological strategies, and emphasized the case management that was found to be effective. Additionally, there was a marked consideration for diverse mental health groups, such as those with substance use disorder and of young age. Most interventions showed a positive effect on reducing psychiatric ED visits.

CONCLUSION

Various initiatives have been implemented worldwide to reduce the number of emergency department visits and the associated burden on healthcare systems. This review highlights the greater need for developing more accessible interventions, as well as setting up a comprehensive community health care system aiming to reduce frequent ED presentations.

Acute psychiatric care: approaches to increasing the range of services and improving access and quality of care

Acute services for mental health crises are very important to service users and their supporters, and consume a substantial share of mental health resources in many countries. However, acute care is often unpopular and sometimes coercive, and the evidence on which models are best for patient experience and outcomes remains surprisingly limited, in part reflecting challenges in conducting studies with people in crisis. Evidence on best ap-proaches to initial assessment and immediate management is particularly lacking, but some innovative models involving extended assessment, brief interventions, and diversifying settings and strategies for providing support are potentially helpful. Acute wards continue to be central in the intensive treatment phase following a crisis, but new approaches need to be developed, evaluated and implemented to reducing coercion, addressing trauma, diversifying treatments and the inpatient workforce, and making decision-making and care collaborative. Intensive home treatment services, acute day units, and community crisis services have supporting evidence in diverting some service users from hospital admission: a greater understanding of how best to implement them in a wide range of contexts and what works best for which service users would be valuable. Approaches to crisis management in the voluntary sector are more flexible and informal: such services have potential to complement and provide valuable learning for statutory sector services, especially for groups who tend to be underserved or disengaged. Such approaches often involve staff with personal experience of mental health crises, who have important potential roles in improving quality of acute care across sectors. Large gaps exist in many low- and middle-income countries, fuelled by poor access to quality mental health care. Responses need to build on a foundation of existing community responses and contextually relevant evidence. The necessity of moving outside formal systems in low-resource settings may lead to wider learning from locally embedded strategies.

Nurses' experiences of encountering patients with mental illness in prehospital emergency care - a qualitative interview study

BACKGROUND

Nurses working in prehospital emergency care (PEC) encounter patients with all types of health conditions. Increasingly, they are encountering patients suffering from mental illness and this trend reflects the worldwide increase in mental illness. There is very little current knowledge of encounters between nurses and patients with mental illness in 'PEC', especially from the nurses' perspectives.

AIM

The aim of the study is to investigate nurses' experiences of encountering patients with mental illness in 'PEC'.

METHODS

The participants were recruited in a region in southeast Sweden (that covers approximately 5600 km2 and has 300,000 inhabitants). In total, 17 nurses consented to participate. The participants were asked to narrate their individual experience of encountering patients with mental illness. The interviews were transcribed verbatim, then analysed with qualitative content analysis.

RESULTS

The result is presented in terms of three themes and eight sub-themes. The main themes are 'Lacking trust in the patient and one's own abilities', 'Being under internal and external influences' and 'Moving towards a genuine nurse-patient relationship'.

CONCLUSION

The results show that nurses strive to lay the foundation for a trusting relationship. Simultaneously nurses encountering is characterized by a mistrust and it is influenced by pre-understanding and emotions when they take care for patients. The findings could be used to develop nurses' readiness and capability to encounter patients with mental illness and to respond appropriately to the patients somatic and mental care needs.

Emergency department use for mental and substance use disorders: descriptive analysis of population-based, linked administrative data in British Columbia, Canada

OBJECTIVES

Information on emergency department (ED) visits for mental and substance use disorders (MSUDs) is important for planning services but has not been explored in British Columbia (BC), Canada. We describe all MSUD ED visits for people ages 15 and older in the province of BC in 2017/2018 and document trends in MSUD ED visits between 2007/2008 and 2017/2018 by disorder group.

DESIGN

Population-based linked administrative data comprised of ED records and physician billings capturing all MSUD ED visits in BC.

SETTING

BC is Canada's westernmost province with a population of approximately 5 million. Permanent residents receive first-dollar coverage for all medically necessary services provided by licensed physicians or in hospitals, including ED services.

POPULATION

All people age >15 with MSUD ED visits during the study period.

MEASURES

All claims with a service location in the ED or corresponding to fee items billed only in the ED were examined alongside ED visits reported through a national reporting system. Patient characteristics (sex/gender, age, location of residence, income, treated disorders and comorbidities) and previous outpatient service use for all ED visits by visit diagnosis are also described.

RESULTS

A total of 72 363 people made 134 063 visits to the ED in 2017/2018 for needs related to MSUD. MSUD ED visits have increased since 2010, particularly visits for substance use and anxiety disorders. People with more frequent visits were more likely to be male, on public prescription drug plans for income assistance, prescribed psychiatric medications, and living in lower-income neighbourhoods. They used more community-based primary care and psychiatry services and had lower continuity of primary care.

CONCLUSIONS

MSUD ED visits are substantial and growing in BC. Findings underscore a need to strengthen and target community healthcare services and adequately resource and support EDs to manage growing patient populations.

The case for improved transdiagnostic detection of first-episode psychosis: Electronic health record cohort study

BACKGROUND

Improving outcomes of a First Episode of Psychosis (FEP) relies on the ability to detect most individuals with emerging psychosis and treat them in specialised Early Intervention (EI) services. Efficacy of current detection strategies is undetermined.

METHODS

RECORD-compliant clinical, 6-year, retrospective, transdiagnostic, lifespan-inclusive, Electronic Health Record (EHR) cohort study, representing real-world secondary mental healthcare in South London and Maudsley (SLaM) NHS. All individuals accessing SLaM in the period 2007-2017 and receiving any ICD-10 diagnosis other than persistent psychosis were included. Descriptive statistics, Kaplan-Meier curves, logistic regression, epidemiological incidence of psychosis in the general population were used to address pathways to care and detection power of EI services for FEP.

RESULTS

A total of 106,706 individuals underwent the 6-year follow-up: they were mostly single (72.57%) males (50.51%) of white ethnicity (60.01%), aged on average 32.96 years, with an average Health Of the Nation Outcome Scale score of 11.12 and mostly affected with F40-48 Neurotic/stress-related/somatoform disorders (27.46%). Their transdiagnostic risk of developing a FEP cumulated to 0.072 (95%CI 0.067-0.077) at 6 years. Those individuals who developed a FEP (n = 1841) entered healthcare mostly (79.02%) through inpatient mental health services (29.76%), community mental health services (29.54%) or accident and emergency departments (19.50%); at the time of FEP onset, most of them (46.43%) were under the acute care pathway. Individuals contacting accident and emergency departments had an increased risk of FEP (OR 2.301, 95%CI 2.095-2.534, P < 0.001). The proportion of SLaM FEP cases that were eligible and under the care of EI services was 0.456 at any time. The epidemiological proportion of FEP cases in the sociodemographically-matched general population that was detected by EI service was 0.373.

CONCLUSIONS

More than half of individuals who develop a FEP remain undetected by current pathways to care and EI services. Improving detection strategies should become a mainstream area in the future generation of early psychosis research.

Modelling the Relationship between Rainfall and Mental Health Using Different Spatial and Temporal Units

Drought is thought to impact upon the mental health of agricultural communities, but studies of this relationship have reported inconsistent results. A source of inconsistency could be the aggregation of data by a single spatiotemporal unit of analysis, which induces the modifiable areal and temporal unit problems. To investigate this, mental health-related emergency department (MHED) presentations among residents of the Wheat Belt region of Western Australia, between 2002 and 2017, were examined. Average daily rainfall was used as a measure of drought. Associations between MHED presentations and rainfall were estimated based on various spatial aggregations of underlying data, at multiple temporal windows. Wide variation amongst results was observed. Despite this, two key features were found: Associations between MHED presentations and rainfall were generally positive when rainfall was measured in summer months (rate ratios up to 1.05 per 0.5 mm of daily rainfall) and generally negative when rainfall was measured in winter months (rate ratios as low as 0.96 per 0.5 mm of daily rainfall). These results demonstrate that the association between drought and mental health is quantifiable; however, the effect size is small and varies depending on the spatial and temporal arrangement of the underlying data. To improve understanding of this association, more studies should be undertaken with longer time spans and examining specific mental health outcomes, using a wide variety of spatiotemporal units.

Months of May: Mental health presentations and the impact of a psychiatric emergency care centre on an inner-city emergency department

OBJECTIVES

The impact of psychiatric emergency care centres (PECCs) on ED mental health (MH) presentations has not been presented. We aim to compare demographics, diagnosis and admission frequency of patients presenting to an inner-city ED with MH complaints, before and for several years after the opening of a PECC.

METHODS

We collected ED patient data for the first 200 'mental health' presentations during the month of May in 2005-2007, and 2015-2017. Data included demographics, diagnosis, post-ED disposition, length of stay in ED, use of the Mental Health Act, and the presence of expressed suicidality and psychotic disorders.

RESULTS

The days to reach 200 MH presentations decreased from 43 days in 2005 to 17 days in 2017. The mean length of ED stay approximately halved with PECC's introduction, with 20% of patients being admitted to PECC. Prior to PECC, 75% of suicidal patients were discharged from ED; after the opening of PECC, 84% of patients expressing suicidality were admitted to PECC; and 73% of patients admitted with psychotic symptoms went to the acute psychiatric ward.

CONCLUSIONS

Between 2005 and 2017, MH presentations to ED became significantly more frequent. The opening of PECC reduced length of stay in ED and provided an admission trajectory for patients expressing suicidality, while retaining the pathway to the acute psychiatric ward for those patients presenting with psychosis.

Registered nurses’ experiences of assessing patients with mental illness in emergency care: A qualitative descriptive study

Patients with mental illness are exposed and experience themselves as not being taken seriously in emergency care. Registered nurses need to assess patients with mental illness from a holistic perspective comprising both a physical and an existential dimension. The aim of the study was to describe registered nurses’ (RNs) experiences of assessing patients with mental illness in emergency care. Twenty-eight RNs in prehospital and in-hospital emergency care were individually interviewed. The interviews were analysed descriptively. The design followed the COREQ-checklist. One main theme ‘A conditional patient assessment’ and two themes; ‘A challenged professional role’ and ‘A limited openness for the patient’, comprising in turn four sub-themes emerged. Although the RNs showed willingness to understand the mental illness aspects of their patients, they were insufficient in their assessments. This implies the importance of developing emergency care RNs’ competence, knowledge and self-confidence in assessments and care of patients with mental illness.
