Increasing impact of mental health presentations on New South Wales public hospital emergency departments 1999-2006

Dynamic modelling of the impact of community-based acute mental health services for children and adolescents

OBJECTIVE

To evaluate the potential impact of the recently announced 'Safeguards' initiative on mental health-related emergency department presentation rates for children and adolescents (0-17 years). This state-funded initiative aims to establish 25 Child and Adolescent Acute Response Teams across New South Wales.

METHODS

We estimated the effects of the 'Safeguards' initiative using a state-level dynamic model of child and adolescent acute mental health care. Potential reductions in total numbers of mental health-related emergency department presentations and re-presentations (i.e. presentations within 3 months of an initial presentation) were assessed via a series of simulation experiments in which we systematically varied the total number of Child and Adolescent Acute Response Teams and the mean duration of care per patient.

RESULTS

Assuming a mean treatment duration of 6 weeks per patient, 25 Child and Adolescent Acute Response Teams are projected to reduce total numbers of mental health-related emergency department presentations and re-presentations over the period 2022-2031 by 15.0% (95% interval, 12.0-18.2%) and 31.7% (26.2-37.8%), respectively. Increasing the total number of Child and Adolescent Acute Response Teams above 25 has minimal additional impact on projected reductions in numbers of emergency department presentations and re-presentations, provided the mean duration of care is no more than 8 weeks. However, where the mean duration of care is greater than 4 weeks, a decrease in the number of Child and Adolescent Acute Response Teams below 25 reduces the potential effectiveness of the 'Safeguards' initiative significantly.

CONCLUSION

Our simulation results indicate that full and timely implementation will be critical if the potentially substantial impact of the 'Safeguards' initiative on demand for hospital-based emergency mental health care is to be realised.

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.

Short stay unit for patients in acute mental health crisis: A case-control study of readmission rates

INTRODUCTION

Past evaluations of psychiatric short stay units have shown positive outcomes for patients, yet very little is known about the factors related to readmissions.

METHODS

A Short Stay Pathway (SSP) has been introduced on the Gold Coast, Australia, for patients in acute mental health crisis with admissions of up to 3 days. Rates of readmissions within 28 days were compared for SSP patients (N = 678), and a diagnosis-matched control group of patients from acute mental health beds (N = 1356). Demographic and clinical factors were considered as predictors of subsequent readmissions.

RESULTS

Average length of stay for SSP patients was 3.4 days, compared to 7.6 days in the control group. 10.6% of SSP patients and 18.4% of the control group were readmitted within 28 days (P < .001). For both groups, a 7-day follow up significantly reduced readmissions (P < .05). Indigenous patients on SSP had higher odds of readmissions than non-Indigenous patients (P < .05), and a diagnosis of a personality disorder increased readmission in the control group but not the SSP group (P < .001).

DISCUSSION

SSP reduced repeated hospitalizations for patients in acute crisis by 42%. An identification of factors related to future admissions can inform future tailoring of this model of care to subgroups of patients.

Emergency department presentations with a mental health diagnosis in Australia, by jurisdiction and by sex, 2004-05 to 2016-17

OBJECTIVES

To examine trends in ED presentations with a mental health diagnosis (MH_dx ) in Australia by jurisdiction and by sex, between 2004-05 and 2016-17.

METHODS

Data were captured in the National Non-Admitted Patient Emergency Department Care Database. Outcomes were the proportion of ED presentations with a principal diagnosis of ICD-10-AM F00-F99 (MH_dx ), and the rate of all ED and MH_dx presentations per 10 000 population.

RESULTS

Between 2004-05 and 2016-17, MH_dx presentations experienced compounding annual growth of 5.9% nationally, and increased from 3.3% to 3.7% of all ED presentations with a diagnosis. Most growth occurred between 2010-11 and 2015-16. Northern Territory (NT) had the highest level of MH_dx presentations per 10 000 population, more than double the Australian average. The proportion of MH_dx presentations was highest in South Australia (SA) in most years, and the average annual proportion of MH_dx presentations was statistically significantly higher than the national average in SA, Queensland (QLD) and Western Australia (WA). The proportion of MH_dx presentations increased in each jurisdiction, with significant increases for Victoria, QLD, WA, Australian Capital Territory and NT. Males experienced greater numbers and rates of all ED and MH_dx presentations, while the proportion of MH_dx presentations was 8% higher for females.

CONCLUSIONS

The proportion of ED presentations for MH conditions, narrowly defined, has increased in all Australian jurisdictions between 2004-05 and 2016-17, but particularly since 2010-11. Differences between jurisdictions indicate jurisdictional specific issues. However, significant or upward trend of MH_dx presentations across all jurisdictions indicates generic issues necessitating concern and policy development at a national level.

Impact of acutely behavioural disturbed patients in the emergency department: A prospective observational study

OBJECTIVE

The present study describes patients with acute behavioural disturbance presenting to the ED, the impact they have on the department and any complications that occur.

METHODS

We performed a prospective observational study of adult patients (>17 years old) requiring parenteral sedation for acute behavioural disturbance over a 13 month period. Demographic data, mode of arrival, indication, drug type and dosing used for sedation were collected. Departmental data were recorded including the staff type and numbers involved and the condition of the department. The main outcomes were complications from sedative medication and injury sustained to patients or staff.

RESULTS

Over the study period 173 patients met inclusion criteria, the majority (n = 104, 60%) were men with a mean age of 38.5 years (standard deviation 14.4); 51% of patients had more than one indication for sedation (n = 89), the commonest being mental health related plus drug intoxication (n = 30, 33.7%). Intoxication was frequently from either alcohol (n = 62, 47%) or methamphetamine (n = 41, 31%). The median number of staff involved was 10 (interquartile range 8-12). Staff members received an injury in 12% (n = 20) of sedations, with only 1% (n = 2) of patients receiving any physical injury; 12% (n = 20) had a minor complication from the sedation medication. No patient had any major complication (apnoea, intubation, arrhythmias or cardiac arrest).

CONCLUSION

Patients with acute behavioural disturbance often have a history of mental illnesses and are commonly intoxicated. These patients have impacts on healthcare resources and pose risks to staff safety, but significant complications to patients do not occur frequently.

Psychiatric Consultations at an Emergency Department in a Metropolitan University Hospital in Northern Japan

Many patients with mental disorders visit emergency departments (EDs). However, the majority of these patients do not receive psychiatric assessment. In the present study, we investigated the detailed proportion of patients with mental disorders visiting an urban ED in the largest northern city in Japan. A retrospective chart review study was performed at a University Hospital from January 2012 to December 2015. The reasons for psychiatric consultations made by ED staff, and the primary psychiatric diagnoses were investigated. Among all living patients, 20% of them received consultations. The most common reason for consultation was suicide attempt followed by agitation or insomnia. Of all diagnoses, organic mental disorder was the most frequent and the mean age was significantly higher than the other diagnostic groups. Our study indicated that the frequency of psychiatric consultation was high. This indicates the high demand for mental health services at the ED. A thorough psychiatric assessment can provide adequate psychiatric services to acute patients; thereby possibly preventing suicide attempters from later actually dying by suicide.

'Nurse specialling': Direct nursing observation in the emergency department compared to other wards of an urban teaching hospital in Sydney

OBJECTIVE

This study examined the patterns of direct observation of patients by nursing staff ('nurse specials') and compared those required for mental health/drug health (MH/DH)-related presentations to other patient groups in different care settings.

METHODS

A retrospective review of nurse special shifts requested during the 2014 calendar year at an urban teaching hospital.

RESULTS

Hospital-wide 14,021 8-hour nursing shifts were ordered for special observation of patients, an average of 39 per day. Of these, 30% were requested for MH/DH-related presentations, with the majority (70%) required for medically unstable patients. However, of the 1917 shifts required in the emergency department, 1841 (96%) were for MH/DH presentations compared to 76 (4%) for patients with unrelated medical conditions (odds ratio 98.2; 95% confidence interval 77.71-124.06, P<0.0001).

CONCLUSIONS

In contrast to the rest of the hospital, emergency department-based nurse special requests were significantly more likely to be for MH/DH presentations. This figure represents a considerable staff and financial burden and may be reduced by diversion or more rapid transfer of such presentations to an appropriate inpatient ward.

Presentations to NSW emergency departments with self-harm, suicidal ideation, or intentional poisoning, 2010-2014

OBJECTIVE

To evaluate population trends in presentations for mental health problems presenting to emergency departments (EDs) in New South Wales during 2010-2014, particularly patients presenting with suicidal ideation, self-harm, or intentional poisoning.

DESIGN, SETTING AND PARTICIPANTS

This was a retrospective, descriptive analysis of linked Emergency Department Data Collection registry data for presentations to NSW public hospital EDs over five calendar years, 2010-2014. Patients were included if they had presented to an ED and a mental health-related diagnosis was recorded as the principal diagnosis.

MAIN OUTCOME MEASURES

Rates of mental health-related presentations to EDs by age group and calendar year, both overall and for the subgroups of self-harm, suicidal ideation and behaviour, and intentional poisoning presentations.

RESULTS

331 493 mental health-related presentations to 115 NSW EDs during 2010-2014 were analysed. The presentation rate was highest for 15-19-year-old patients (2014: 2167 per 100 000 population), but had grown most rapidly for 10-14-year-old children (13.8% per year). The combined number of presentations for suicidal ideation, self-harm, or intentional poisoning increased in all age groups, other than those aged 0-9 years; the greatest increase was for the 10-19-year-old age group (27% per year).

CONCLUSIONS

The rate of mental health presentations to EDs increased significantly in NSW between 2010 and 2014, particularly presentations by adolescents. Urgent action is needed to provide better access to adolescent mental health services in the community and to enhance ED models of mental health care. The underlying drivers of this trend should be investigated to improve mental health care.

Motivational interviewing to enhance treatment attendance in mental health settings: A systematic review and meta-analysis

WHAT IS KNOWN ON THE SUBJECT?: Despite differences between samples, some literature reviews have suggested that MI is effective in enhancing treatment attendance for individuals with mental health issues. Little is known regarding the effects of MI as a pre-treatment on individuals who are not seeking treatment for mental health issues. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This systematic review of the literature and meta-analysis demonstrates that MI is most beneficial for individuals who are not seeking mental health treatment. MI represents an opportunity for health promotion when patients are unmotivated but may otherwise be amenable to an intervention. MI is effective as a pre-treatment intervention to motivate individuals to attend further post-MI treatment and counselling. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: MI is a process and a useful tool for clinicians in all therapeutic interactions, to motivate their patients to seek further assistance for mental heath issues. Health promotion and encouragement to attend further treatment sessions can be facilitated through telephone contact.

ABSTRACT

Introduction The stages of change model suggests that individuals seeking treatment are in the "preparation" or the "action" stage of change, which is the desired outcome of successful Motivational Interviewing (MI) interventions. MI is known to enhance treatment attendance among individuals with mental health problems. Aim This study examined the published research on MI as a pre-treatment to enhance attendance among individuals treatment-seeking and non-treatment-seeking for mental health issues. Methods Fourteen randomized controlled trials were identified, and MI efficacy was examined dichotomously: attendance or non-attendance for post-MI therapy. Subgroup analysis investigated treatment-seeking and non-treatment-seeking groups. Results Despite wide variations in sample sizes, blinding and monitoring, intervention fidelity was absent in the majority of published studies. Meta-analysis revealed that MI pre-treatment improved attendance relative to comparison groups. Conclusions Individuals not seeking treatment for mental health issues benefited the most from MI. Despite differences in MI treatment intensity, short interventions were as effective as longer interventions, whereas two MI sessions for as little as 15 min were effective in enhancing treatment attendance. Implications for Practice Motivational interviewing is a useful tool for clinicians in all therapeutic interactions to help motivate patients to seek assistance for mental health issues.

Predictors of repeat visits to hospital psychiatric emergency departments in Malaga (Spain) and in Lisbon (Portugal)

OBJECTIVE

This study describes the profile of people with mental disorders attending emergency departments (EDs) in two countries and to identify specific mental disorders associated with repeat emergency visits.

METHODS

Retrospective analyses of 1 year of EDs data from two hospitals with psychiatric departments, one in Amadora/Sintra (Lisbon, Portugal, 2008) and the other in Malaga (Spain, 2009), were carried out. To determine which mental disorders were associated with repeat visits in each setting, negative binomial models were calculated.

RESULTS

There were 5141 visits for a mental disorder made by 3667 patients. Patients with affective disorder were the most frequent (32.2%). Among all mental health patients, 19.9% had at least one repeat visit during the year. For the two EDs setting combined, patients with personality disorders (incidence rate ratio (IRR)=3.79, 95% CI: 2.39 to 6.02) and psychotic disorders (IRR=1.46, 95% CI: 1.13 to 1.89) were more likely to have repeat visits compared with patients with affective disorders, whereas mental disorders due to psychoactive substance use (IRR=0.52, 95% CI: 0.37 to 0.73) was associated with lower likelihood of repeat visits. Nearly all significant differences were attributable to the Malaga sample, where patients with personality disorders were four times more likely to have repeat EDs visits compared with patients with affective disorders. However, at both sites, patients with mental disorders due to psychoactive substance use were less likely to have repeat visits.

CONCLUSIONS

Certain mental disorders may be predictive of more frequent ED visits. The different results for each country suggest that further studies might focus not only on the characteristics of patients, but also on local healthcare organisation.

Epidemiology of Mental Health Attendances at Emergency Departments: Systematic Review and Meta-Analysis

Background

The characteristics of Emergency Department (ED) attendances due to mental or behavioural health disorders need to be described to enable appropriate development of services. We aimed to describe the epidemiology of mental health-related ED attendances within health care systems free at the point of access, including clinical reason for presentation, previous service use, and patient sociodemographic characteristics.

Method

Systematic review and meta-analysis of observational studies describing ED attendances by patients with common mental health conditions.

Findings

18 studies from seven countries met eligibility criteria. Patients attending due to mental or behavioural health disorders accounted for 4% of ED attendances; a third were due to self-harm or suicidal ideation. 58.1% of attendees had a history of psychiatric illness and up to 58% were admitted. The majority of studies were single site and of low quality so results must be interpreted cautiously.

Conclusions

Prevalence studies of mental health-related ED attendances are required to enable the development of services to meet specific needs.

Emergency Department Visits by Older Adults with Mental Illness in North Carolina

Introduction

We analyzed emergency department (ED) visits by patients with mental health disorders (MHDs) in North Carolina from 2008–2010 to determine frequencies and characteristics of ED visits by older adults with MHDs.

Methods

We extracted ED visit data from the North Carolina Disease Event Tracking and Epidemiologic Collection Tool (NC DETECT). We defined mental health visits as visits with a mental health ICD-9-CM diagnostic code, and organized MHDs into clinically similar groups for analysis.

Results

Those ≥65 with MHDs accounted for 27.3% of all MHD ED visits, and 51.2% were admitted. The most common MHD diagnoses for this age group were psychosis, and stress/anxiety/depression.

Conclusion

Older adults with MHDs account for over one-quarter of ED patients with MHDs, and their numbers will continue to increase as the “boomer” population ages. We must anticipate and prepare for the MHD-related needs of the elderly.

No longer 'flying blind': how access has changed emergency mental health care in rural and remote emergency departments, a qualitative study

Background

Mental health presentations are considered to be a difficult aspect of emergency care. Although emergency department (ED) staff is qualified to provide emergency mental health care, for some, such presentations pose a challenge to their training, confidence, and time. Providing access to relevant and responsive specialist mental health care can influence care and management for these patients. The Mental Health Emergency Care-Rural Access Program (MHEC-RAP) is a telepsychiatry program that was established to improve access to specialist emergency mental health care across rural and remote western NSW, Australia.

Method

This study uses interviews with ED providers to understand their experience of managing emergency mental health patients and their use of MHEC-RAP. The lens of access was applied to assess program impact and inform continuing program development.

Results

With MHEC-RAP, these ED providers are no longer ‘flying blind’. They are also more confident to manage and care for emergency mental health patients locally. For these providers, access to specialists who are able to conduct assessments and provide relevant and responsive advice for emergency mental health presentations was valued. Assessing the fit between the consumer and service as a requirement for the development, evaluation, and ongoing management of the service should result in decisions about design and delivery that achieve improved access to care and meet the needs of their consumers. The experience of these providers prior to MHEC-RAP is consistent with that reported in other rural and remote populations suggesting that MHEC-RAP could address limitations in access to specialist care and change the provision of emergency mental health care elsewhere.

Conclusion

MHEC-RAP has not only provided access to specialist mental health care for local ED providers, but it has changed their practice and perspective. MHEC-RAP could be adapted for implementation elsewhere. Provider experience confirms that the program is accessible and offers insights to those considering how to establish an emergency telepyschiatry service in other settings.

Survey of an Australian general emergency department: estimated prevalence of mental health disorders

Compared to the general population, people with mental health disorders have an increased risk of morbidity and mortality, and are associated with higher health-care costs and lost societal productivity. Evidence indicates that more people are presenting to emergency departments with mental health disorders and that this group represents a disproportionately large number of emergency department attendees. The study results indicate that around a third of people who attended the emergency department may have had a mental health disorder, which is more than that found in the general adult Australian population. The results also suggest that the majority of emergency department attendees that have a mental health disorder are not identified at this opportunistic point of contact. The emergency department is an ideal point of contact to screen people for mental health problems. If problems are identified early, and treatment is started early, then it is likely that more people would be helped before their mental health problem became severe. However, increased identification of mental health problems may have implications for mental health services in terms of workload and delivery. The aim of this study was to estimate the prevalence of mental health disorders in an Australian general emergency department. A cross-sectional survey was used to screen a sample of 708 patients, using the Kessler Psychological Distress Scale (K10). The mean age of participants was 50.2 years, and their mean K10 score was 19.96 (SD 7.83), with 24% categorized as having high or very high psychological distress. Seventeen per cent self-reported having a mental health issue. Post-probability calculations based on observed K10 scores estimated that 37% of participants had an actual mental health disorder. The results suggest the prevalence of mental health disorder is significantly higher in emergency department attendees than Australian population norms, supporting the contention that a substantial proportion of ED attendees has a mental health disorder that, in the majority of cases, is not investigated at this point of contact. There is potential to screen all emergency department attendees for the presence of mental health disorder; early identification of mental illness would enable early referral for treatment. However, if all patients are screened, then it is likely that more mental health conditions will be picked up. The implications for mental health nursing are that this may increase workload.

Evaluation of a nurse practitioner-led extended hours mental health liaison nurse service based in the emergency department

Objective To evaluate a nurse practitioner (NP)-led extended hours mental health liaison nurse (MHLN) service based in the emergency department (ED) of an inner city teaching hospital in Sydney and to explicate a model of care that is transferable across a broad range of ED settings, both in metropolitan and rural contexts. Methods This mixed-methods evaluation encompassed descriptive data on ED mental health presentations, quantifying waiting times for MHLN involvement and interviews with MHLN team members at the commencement of the evaluation and 12 months later. Interviews were also conducted with a snapshot of ED patients, and a sample of ED and psychiatry staff. Results The expanded MHLN service was rapidly incorporated into the ED structure, enthusiastically endorsed by ED patients and highly valued by staff and the organisation. The MHLN team saw 55% of referred patients within the first hour of arrival (frequently before medical assessment), thereby initiating and expediting co-ordination of care at an early stage of the ED process. Conclusions An NP-led extended hours MHLN team based in the ED provides prompt and effective access to specialised mental health care for people with ‘undifferentiated health problems’, and removes a significant workload from nursing and medical staff. Embedding the NP-led MHLN service within the ED structure was pivotal to the success and sustainability of this model of care. What is known about the topic? Mental health liaison nurse (MHLN) services have existed in emergency departments (EDs) in Australia and internationally for many years. However, there is great variation in the way these services are structured and no standardised model of care has been explicated. What does this paper add? Findings from this evaluation indicate that a nurse practitioner-led extended hours MHLN service integrated within the ED team structure provides prompt access to specialised mental health care to people with undifferentiated health problems, and removes a significant workload from ED nursing and medical staff. What are the implications for practitioners? Mental health nurse-led service provision based in the ED is a safe, flexible and effective method of enhancing access to health care that is adaptable to broad range of settings. ED ownership of this model of care is pivotal to the successful implementation and sustainability of MHLN services.
