Person-centred crisis support services as alternatives to emergency departments: a systematic scoping review.

To identify, critically appraise, and synthesise the published and grey literature on person-centred crisis support services as an alternative to support in emergency departments (EDs) for people experiencing mental health crises. This scoping review explores the characteristics and outcomes of these services. A systematic scoping review was undertaken to identify publications describing person-centred crisis support services and their outcomes. Search strings were applied to multiple databases, and publications were subjected to quality appraisal. The review process was informed by The Joanna Briggs Institute (JBI) Manual for Evidence Synthesis and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR). Thirteen publications were included in the narrative synthesis, and these considered eight separate crisis support services. The methodological quality of the publications included was limited. Key findings were positive visitors' experiences, high rates of ED deflection, and overlaps between repeat visits, crises prevention, and hospital avoidance. Key recommendations included increasing opening hours and capacity and improving service awareness and accessibility. The available evidence suggests that person-centred crisis support services are perceived by stakeholders as safe and effective alternatives to EDs for people experiencing mental health crises, providing more timely and appropriate care while reducing ED mental health presentations. Due to the limited quality of the publications included, high-quality research is needed to better understand the model and confirm the findings reported in this review.

Socioeconomic inequity in the utilization of healthcare among people with eating disorders in Australia.

Little is known about socioeconomic equity in access to healthcare among people with eating disorders in Australia. This study aims to measure the extent of inequity in eating disorder-related healthcare utilization, analyze trends, and explore the sources of inequalities using New South Wales (NSW) administrative linked health data for 2005 to 2020. Socioeconomic inequities were measured using concentration index approach, and decomposition analysis was conducted to explain the factors accounting for inequality. Healthcare utilization included: public inpatient admissions, private inpatient admissions, visits to public mental health outpatient clinics and emergency department visits, with three different measures (probability of visit, total and conditional number of visits) for each outcome. Private hospital admissions due to eating disorders were concentrated among individuals from higher socioeconomic status (SES) from 2005 to 2020. There was no significant inequity in the probability of public hospital admissions for the same period. Public outpatient visits were utilized more by people from lower SES from 2008 to 2020. Emergency department visits were equitable, but more utilized by those from lower SES in 2020. Public hospital and emergency department services were equitably used by people with eating disorders in NSW, but individuals from high SES were more likely to be admitted to private hospitals for eating disorder care. Use of public hospital outpatient services was higher for those from lower SES. These findings can assist policymakers in understanding the equity of the healthcare system and developing programs to improve fairness in eating disorder-related healthcare in NSW.

International comparison of hospitalizations and emergency department visits related to mental health conditions across high-income countries before and during the COVID-19 pandemic.

To explore variation in rates of acute care utilization for mental health conditions, including hospitalizations and emergency department (ED) visits, across high-income countries before and during the COVID-19 pandemic. Administrative patient-level data between 2017 and 2020 of eight high-income countries: Canada, England, Finland, France, New Zealand, Spain, Switzerland, and the United States (US). Multi-country retrospective observational study using a federated data approach that evaluated age-sex standardized rates of hospitalizations and ED visits for mental health conditions. There was significant variation in rates of acute mental health care utilization across countries. Among the subset of four countries with both hospitalization and ED data, the US had the highest pre-COVID-19 combined average annual acute care rate of 1613 episodes/100,000 people (95% CI: 1428, 1797). Finland had the lowest rate of 776 (686, 866). When examining hospitalization rates only, France had the highest rate of inpatient hospitalizations of 988/100,000 (95% CI 858, 1118) while Spain had the lowest at 87/100,000 (95% CI 76, 99). For ED rates for mental health conditions, the US had the highest rate of 958/100,000 (95% CI 861, 1055) while France had the lowest rate with 241/100,000 (95% CI 216, 265). Notable shifts coinciding with the onset of the COVID-19 pandemic were observed including a substitution of care setting in the US from ED to inpatient care, and overall declines in acute care utilization in Canada and France. The study underscores the importance of understanding and addressing variation in acute care utilization for mental health conditions, including the differential effect of COVID-19, across different health care systems. Further research is needed to elucidate the extent to which factors such as workforce capacity, access barriers, financial incentives, COVID-19 preparedness, and community-based care may contribute to these variations. Approximately one billion people globally live with a mental health condition, with significant consequences for individuals and societies. Rates of mental health diagnoses vary across high-income countries, with substantial differences in access to effective care. The COVID-19 pandemic has exacerbated mental health challenges globally, with varying impacts across countries. This study provides a comprehensive international comparison of hospitalization and emergency department visit rates for mental health conditions across eight high-income countries. It highlights significant variations in acute care utilization patterns, particularly in countries that are more likely to care for people with mental health conditions in emergency departments rather than inpatient facilities The study identifies temporal and cross-country differences in acute care management of mental health conditions coinciding with the onset of the COVID-19 pandemic.

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 department mental health presentations in young children: a retrospective chart review

AimTo characterise key features of young people presenting to the emergency department (ED) with a mental health complaint when comparing children (aged 7 to 12 years) and teenagers (13 years and greater).MethodsRetrospective review of all ED mental health presentations in children aged 7–17 years presenting over a 12‐month period in 2018 to a tertiary children's hospital in Victoria, Australia. Univariate analyses were carried out to examine the relationship between children and teenagers and a number of key presentation variables. Odds Ratios (ORs) and 95% Confidence Intervals (CIs) were calculated for ED management outcomes.ResultsThere were 1691 ED mental health presentations in 2018. Of these presentations, 407 (24%) were children aged 12 years or less. The remaining 76% (1284) were teenagers. The younger aged cohort were more likely to be male (OR 2.43, CI 1.92–3.08) and have a past history of autism spectrum disorder (OR 1.92, CI 1.45–1.84). They were more likely to have a presenting complaint of acute behavioural disturbance (OR 2.03, CI 1.59–2.60), be physically restrained (OR 2.01, CI 1.18–3.37) and have sedative medication provided (OR 2.87, CI 1.63–5.04). The older aged cohort were more likely to have a past history of depression (OR 0.19, CI 0.12–0.29) and a presenting complaint of intentional self‐poisoning (OR 0.33, CI 0.15–0.65).ConclusionsChildren aged 12 years or less represent one‐quarter of all young people presenting to the ED with a mental health concern. They experience high rates of acute behavioural disturbance and are more likely to require restrictive interventions during their presentation.

Provision of Behavioral Health Services at Community Health Centers and Hospital Emergency Department Visits.

Numerous US patients seek the hospital emergency department (ED) for behavioral health care. Community Health Centers (CHCs) offer a potential channel for redirecting many to a more patient-centered, lower cost setting. The aim of this study was to identify unique market areas serviced by CHCs and to examine whether CHCs are effective in offsetting behavioral health ED visits. We identified CHC-year specific service areas using patient origin zip codes. We then estimated random effects models applied to 42 federally qualified CHCs operating in New York State during 2013-2020. The dependent variables were numbers of ED mental health (substance use disorder) visits per capita in a CHC's service area, drawn from HCUP State Emergency Department Databases. Key explanatory variables measured CHC number of mental health (substance use disorder) visits, number of unique mental health (substance use disorder) patients, and mental health (substance use disorder) intensity, obtained from the HRSA Uniform Data System. Controlling for population, we observed small negative effects of CHC behavioral health integration in explaining ED behavioral health utilization. Measures of mental health utilization in CHCs were associated with 1.3%-9.3% fewer mental health emergency department visits per capita in Community Health Centers' service areas. Measures of substance use disorder utilization in Community Health Centers were associated with 1.3%-3.0% fewer emergency department visits per capita. Results suggest that behavioral health integration in CHCs may reduce reliance on hospital EDs, but that policymakers explore more avenues for regional coordination strategies that align services between CHCs and local hospitals.

Certified Community Behavioral Health Clinic Demonstration Impact on Health Care Utilization Among Non-Medicaid Patients with Severe Mental Illnesses.

In 2017, the Certified Community Behavioral Health Clinic (CCBHC) demonstration was implemented in New York State to redesign care delivery and financing for behavioral health services. Although CCBHC primarily targeted Medicaid patients, it was hypothesized that the clinic-level benefits of CCBHC were expected to impact even non-Medicaid patients treated in CCBHCs. To test this hypothesis, this study conducted a health insurance claims data analysis of non-Medicaid (ie, commercial and Medicare) patients with severe mental illnesses, comparing a cohort of CCBHC-treated patients with a propensity score-matched comparison cohort of patients treated by non-CCBHC clinics on rates of mental health service utilization, hospitalization, and emergency department (ED) visits. The data suggested CCBHC was associated with more than 10% increase in outpatient mental health service utilization by the patients' second year of CCBHC exposure, accompanied by similarly significant reductions in the rates of all-cause ED visits and non-psychiatric hospitalization. These findings suggest that for behavioral health clinics that serve a sufficiently large population of Medicaid, the impact of innovative clinical redesign attributable to CCBHC is likely to extend to all patients treated by them.

Disproportionate mental health presentations to emergency departments in a coastal regional community in Australia of first nation people.

Emergency department (ED) presentations for mental health (MH) help-seeking have been rising rapidly in recent years. This research aims to identify the service usage demographic for people seeking MH care in the ED, specifically in this case, to understand the usage by First Nation people. This retrospective cohort study examined the sociodemographic and presentation characteristics of individuals seeking MH care in two EDs between 2016 and 2021. Data were collected using existing records and analysed using descriptive univariate analysis with statistical significance between the two sites determined using chi-squared test, p < 0.05. The overall data presented in this analysis show an overall ED mental health presentation rate of 12.02% for those who identified as 'Aboriginal but not Torres Strait Islander origin', 0.36% as 'Both Aboriginal and Torres Strait Islander' and 0.27% as 'Torres Strait Islander' totalling 12.63%. This is an overrepresentation compared to the regional population of 4.9%. One site recorded 14.1% of ED presentations that identified as Aboriginal and/or Torres Strait Islander, over double the site's demographic of 6.3%. Given the disproportionately high representation of First Nation people in MH-related ED presentations, further research is required to prioritise a First Nation research perspective that draws on First Nation research methods, such as yarning and storytelling to understand the unique cultural needs and challenges experienced by First Nation people accessing MH care via ED. Understanding the demographic is but one step in supporting the Cultural Safety needs of First Nation people. Additionally, research should be designed, governed and led by First Nation researchers.

Characteristics and outcomes of people in suicidal crisis at two emergency departments: a service evaluation.

Emergency departments (EDs) provide critical opportunities for nurses to support suicide prevention. This article details a service evaluation that was undertaken to explore the characteristics and outcomes of people in suicidal crisis at two EDs in the East of England during June 2023. Data routinely collected by the ED mental health liaison team were combined with a retrospective case note review of the local NHS mental health trust's electronic patient records. Attendees had a mean age of 35 years and seven months, and were often diagnosed with depression or emotionally unstable personality disorder. Most had a history of self-harm and were currently known to mental health services. Suicide-specific interventions were rarely recorded by nurses and relapse behaviours were prevalent after presentation. Local and national suicide prevention strategies should encourage nurses to address gaps in support, thereby improving patients' experiences in and beyond the ED.

Severe Maternal Morbidity and Mental Health Hospitalizations or Emergency Department Visits

Severe maternal morbidity (SMM) can have long-term health consequences for the affected mother. The association between SMM and future maternal mental health conditions has not been well studied. To assess the association between SMM in the first recorded birth and the risk of hospitalization or emergency department (ED) visits for a mental health condition over a 13-year period. This population-based retrospective cohort study used data from postpartum individuals aged 18 to 55 years with a first hospital delivery between 2008 and 2021 in 11 provinces and territories in Canada, except Québec. Data were analyzed from January to June 2023. SMM, defined as a composite of conditions, such as septic shock, severe preeclampsia or eclampsia, severe hemorrhage with intervention, or other complications, occurring after 20 weeks' gestation and up to 42 days after a first delivery. The main outcome was a hospitalization or ED visit for a mental health condition, including mood and anxiety disorders, substance use, schizophrenia, and other psychotic disorder, or suicidality or self-harm event, arising at least 43 days after the first birth hospitalization. Cox regression models generated hazard ratios with 95% CIs, adjusted for baseline maternal comorbidities, maternal age at delivery, income quintile, type of residence, hospital type, and delivery year. Of 2 026 594 individuals with a first hospital delivery, 1 579 392 individuals (mean [SD] age, 30.0 [5.4] years) had complete ED and hospital records and were included in analyses; among these, 35 825 individuals (2.3%) had SMM. Compared with individuals without SMM, those with SMM were older (mean [SD] age, 29.9 [5.4] years vs 30.7 [6.0] years), were more likely to deliver in a teaching tertiary care hospital (40.8% vs 51.1%), and to have preexisting conditions (eg, ≥2 conditions: 1.2% vs 5.3%), gestational diabetes (8.2% vs 11.7%), stillbirth (0.5% vs 1.6%), preterm birth (7.7% vs 25.0%), or cesarean delivery (31.0% vs 54.3%). After a median (IQR) duration of 2.6 (1.3-6.4) years, 1287 (96.1 per 10 000) individuals with SMM had a mental health hospitalization or ED visit, compared with 41 779 (73.2 per 10 000) individuals without SMM (adjusted hazard ratio, 1.26 [95% CI, 1.19-1.34]). In this cohort study of postpartum individuals with and without SMM in pregnancy and delivery, there was an increased risk of mental health hospitalizations or ED visits up to 13 years after a delivery complicated by SMM. Enhanced surveillance and provision of postpartum mental health resources may be especially important after SMM.

Use of Electronic Health Record-Based Measures to Assess Quality of Care for Pediatric Agitation.

Acute agitation during pediatric mental health emergency department (ED) visits presents safety risks to patients and staff. We previously convened multidisciplinary stakeholders who prioritized 20 proposed quality measures for pediatric acute agitation management. Our objectives were to assess feasibility of evaluating performance on these quality measures using electronic health record (EHR) data and to examine performance variation across 3 EDs. At a children's hospital and 2 nonchildren's hospitals, we assessed feasibility of evaluating quality measures for pediatric acute agitation management using structured EHR data elements. We retrospectively evaluated measure performance during ED visits by children 5 to 17 years old who presented for a mental health condition, received medication for agitation, or received physical restraints from July 2020 to June 2021. Bivariate and multivariable regression were used to examine measure performance by patient characteristics and hospital. We identified 2785 mental health ED visits, 275 visits with medication given for agitation, and 35 visits with physical restraints. Performance was feasible to measure using EHR data for 10 measures. Nine measures varied by patient characteristics, including 4.87 times higher adjusted odds (95% confidence interval 1.28-18.54) of physical restraint use among children with versus without autism spectrum disorder. Four measures varied by hospital, with physical restraint use varying from 0.5% to 3.3% of mental health ED visits across hospitals. Quality of care for pediatric acute agitation management was feasible to evaluate using EHR-derived quality measures. Variation in performance across patient characteristics and hospitals highlights opportunities to improve care quality.

Development and Implementation of a Pediatric Nursing Emergency Behavioral Health Assessment Tool

IntroductionThe national pediatric mental and behavioral health crisis dramatically increased emergency department mental and behavioral health visits and changed emergency nursing practice. Acuity assessment determines patient severity level and supports appropriate resources and interventions. There are no established nursing tools that assess pediatric mental or behavioral health acuity in the emergency department setting. Our goal was to develop and implement the novel pediatric emergency nurse Emergency Behavioral Health Acuity Assessment Tool. MethodsThis quality-improvement project used the plan, do, study, act model to design/refine the Emergency Behavioral Health Acuity Assessment Tool and a non-experimental descriptive design to assess outcomes. The setting was a 47-bed urban level 1 pediatric trauma center with more than 60,000 annual visits. The team designed the tool using published evidence, emergency nurse feedback, and expert opinion. The tool objectively captured patient acuity and suggested acuity-specific nursing interventions. Project outcomes included acuity, length-of-stay, restraint use, and patient/staff injuries. Analyses included descriptive statistics and correlations. ResultsWith over 3000 annual mental/behavioral-related visits, the emergency department had an average daily census of 23 mental and behavioral health patients. Implementation occurred in August 2021. The Emergency Behavioral Health Acuity Assessment Tool dashboard provided the number of patients, patient location, and acuity. Length-of-stay did not change; however, patient restraint use and patient/staff injuries declined. Number of restraints positively correlated with moderate acuity levels (r = 0.472, P = 0.036). DiscussionFor emergency nurses, the Emergency Behavioral Health Acuity Assessment Tool provided an objective measure of patient acuity. Targeted interventions can improve the care of this population.

Pediatric mental health emergency department visits from 2017 to 2022: A multicenter study.

The COVID-19 pandemic adversely affected children's mental health (MH) and changed patterns of MH emergency department (ED) utilization. Our objective was to assess how pediatric MH ED visits during the COVID-19 pandemic differed from expected prepandemic trends. We retrospectively studied MH ED visits by children 5 to <18 years old at nine U.S. hospitals participating in the Pediatric Emergency Care Applied Research Network Registry from 2017 to 2022. We described visit length by time period: prepandemic (January 2017-February 2020), early pandemic (March 2020-December 2020), midpandemic (2021), and late pandemic (2022). We estimated expected visit rates from prepandemic data using multivariable Poisson regression models. We calculated rate ratios (RRs) of observed to expected visits per 30 days during each pandemic time period, overall and by sociodemographic and clinical characteristics. We identified 175,979 pediatric MH ED visits. Visit length exceeded 12 h for 7.3% prepandemic, 8.4% early pandemic, 15.0% midpandemic, and 19.2% late pandemic visits. During the early pandemic, observed visits per 30 days decreased relative to expected rates (RR 0.80, 95% confidence interval [CI] 0.78-0.84), were similar to expected rates during the midpandemic (RR 1.01, 95% CI 0.96-1.07), and then decreased below expected rates during the late pandemic (RR 0.92, 95% CI 0.86-0.98). During the late pandemic, visit rates were higher than expected for females (RR 1.10, 95% CI 1.02-1.20) and for bipolar disorders (RR 1.83, 95% CI 1.38-2.75), schizophrenia spectrum disorders (RR 1.55, 95% CI 1.10-2.59), and substance-related and addictive disorders (RR 1.50, 95% CI 1.18-2.05). During the late pandemic, pediatric MH ED visits decreased below expected rates; however, visits by females and for specific conditions remained elevated, indicating a need for increased attention to these groups. Prolonged ED visit lengths may reflect inadequate availability of MH services.

Re-imagining crisis care: experiences of delivering and receiving the Assured brief psychological intervention for people presenting to Emergency Departments with self-harm.

Risk of suicide is increased immediately following emergency department (ED) attendance for self-harm. Evidence suggests that brief psychological interventions delivered in EDs are effective for self-harm. The Assured intervention comprises an enhanced biopsychosocial assessment in the ED, collaborative safety planning and three rapid solution focused follow-up sessions. We addressed the following research questions: What were ED mental health liaison practitioners' and patients' experiences of the Assured intervention? What were the barriers and facilitators? What might the mechanisms be for improving experiences and outcomes? We conducted a feasibility study of the Assured intervention in four EDs in Southeast England. Semi-structured interviews were conducted with 13 practitioners and 27 patients. Interviews were transcribed, coded line-by-line in Nvivo and thematically analysed using an inductive approach. Inter-rater reliability was calculated with a kappa coefficient of 0.744.

Examining sexual minority engagement in recovery community centers

IntroductionResearch indicates that sexual minority (SM) individuals with alcohol and other drug use disorders may underutilize recovery resources generally but be more likely to use recovery community centers (RCCs). To inform recovery supports, this study characterized SM and heterosexual RCC members by demographics and clinical and recovery support service utilization. MethodsCross-sectional secondary analyses compared SM and heterosexual RCC members in the northeastern U.S. (n = 337). Qualitative analyses coded the top three recovery facilitators. ResultsOf the 337 participants (Meanage[SD] = 40.98[12.38], 51.8 % female), SM RCC members were more likely than heterosexuals to endorse lifetime psychiatric diagnoses and emergency department mental health treatment (p < .01). RCC service utilization and qualitatively derived recovery facilitators were mostly consistent across groups. ConclusionsRCCs engaged SM individuals in recovery in ways consistent with heterosexuals. Despite otherwise vastly similar demographic characteristics across sexual identity, findings suggest a need for additional mental health resources for SM individuals in recovery.

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

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. 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. 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). 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.

Predictors of mental health emergency department visits and psychiatric hospitalizations in children in foster care

BackgroundDespite the promise of safe, nurturing environments, children in foster care are at significantly elevated risk of mental health disorders. ObjectiveTo identify factors associated with increased mental health emergency department (ED) visits and psychiatric hospitalizations for children in foster care. ParticipantsChildren aged 4–18 years in child welfare services custody who presented to a foster care clinic from December 2017 to January 2020 (N = 311). MethodsA descriptive cohort study was conducted to collect semi-structured data on a child’s foster care placement history, trauma history, reported behavioral concerns, academic delay, and demographics after new foster care placement. Mental health ED visits and psychiatric hospitalizations within one year of the foster clinic visit were identified using a health information exchange platform. Simple and multiple logistic regression was used to determine unadjusted and adjusted odds ratios for associations of independent variables with mental health ED visits and psychiatric hospitalizations. ResultsIn the study population, most children (78.5 %) were placed with foster families, followed by group homes (18.3 %) and kinship care (3.2 %). Within one year of the foster clinic visit, 24.1 % and 7.4 % of patients had ≥1 ED visit for mental health concerns or ≥1 psychiatric hospitalization, respectively. While children with increased prior placements and group home placement had increased odds of ≥1 ED visit in univariate analyses, no significant association was seen in multivariable analysis. More than half of the children placed in group homes had at least one mental health ED visit compared to 17.4 % of children placed with foster families. ConclusionsChildren placed into out-of-home care have high rates of mental health ED visits and psychiatric hospitalizations. Understanding predictors of poor mental health and associated service utilization can help guide the allocation of resources for better prevention.

Police-reported family violence victimisation or perpetration and mental health-related emergency department presentations: an Australian data-linkage study

BackgroundFamily violence is a leading social determinant of mental ill-health but its link to mental health-related emergency department presentations is poorly understood. Existing research has largely used retrospective designs with a focus on victimisation, typically among women. We examined whether police-reported family violence victimisation and perpetration were prospectively associated with mental health emergency department presentations in women and men. We also identified family violence risk and vulnerability characteristics associated with such presentations.MethodsDemographics, prior police involvement, and individual and relationship vulnerabilities were provided by Victoria Police for 1520 affected family members (i.e., primary victims) and 1470 respondents (i.e., persons alleged to have perpetrated family violence) from family violence reports in 2016–17. Emergency mental health presentations 22–30 months post-family-violence report were determined through linkage with the Victorian Emergency Minimum Dataset and compared to statewide presentations.ResultsEmergency mental health presentations during follow-up were identified in 14.3% of the family violence sample, with 1.9% presenting for self-harm. Mental health presentation rates per 1,000 people were markedly higher among affected family members and respondents of both sexes and all ages than in the general population, except for male affected family members aged 45 + . Adjusting for age and sex, the mental health presentation rate was 6 and 11 times higher among affected family members and respondents, respectively, than in the general population. Individual vulnerabilities were more closely related to risk of emergency mental health presentations than relationship characteristics.ConclusionsPolice-recorded family violence is associated with increased mental health-related emergency department presentations over the short-to-medium term. Strengthened cross-sector collaboration is needed to identify, address, and refer individuals with overlapping family violence and mental health needs and to improve victims’ and perpetrators’ access to community mental health and related services. This should help prevent individuals from reaching a crisis point in their mental health.

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.

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. 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 24months post-PDU implementation compared to that in the 24months pre-PDU implementation. 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. 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.

Involuntary sedation of patients in the emergency department for mental health: A retrospective cohort study

BackgroundInvoluntary sedation of agitated mental health patients in the Emergency Department (ED) is standard practice to obtain accurate medical assessments and maintain safety. However, the rate of this practice and what factors are associated with the use of involuntary sedation is unknown. The purpose of this study was to obtain baseline data on involuntary sedation in our EDs. MethodsRetrospective chart review of patients with ED visits for mental health care in 2020–2021. Patients >12 years old who received both a psychiatry consultation and involuntary sedation were included. Data variables included demographics, medical and mental health diagnoses, sedatives given, substance use, ED length of stay, and disposition. The primary outcome was repeated involuntary sedation. ResultsInvoluntary sedation was used in 18.8% of the mental health patients screened for study inclusion. 334 patients were included in the study cohort and 31.6% (n = 106) required repeated involuntary sedation. Their average age was 35.5 ± 13.5 years with 58.4% men, 40.1% women, and 1.2% transgender persons. Most (90.0%, n = 299) had prior mental health diagnoses with the most common being substance use disorder (38.9%, n = 130), bipolar disorder (34.1%, n = 114), depressive disorder (29.0%, n = 97), and schizophrenia (24.3%, n = 81). Two-thirds (65.9%, n = 220) had current substance use and 41.9% (n = 142) reported current use with a chemical associated with aggression. Hospital security was called for 73.1% (n = 244). Current cocaine, methamphetamines, or alcohol use was associated with decreased odds of repeated sedation (0.52 OR, 95% CI 0.32–0.85). Prior mental health diagnosis and non-white race were associated with increased odds of repeated sedation. In the multivariable regression, the effect of race was more significant. ConclusionsInvoluntary sedation was used in 18.8% of ED patients for mental health care and almost a third were repeatedly sedated, with race being a potential risk factor for repeated sedation. ED care could benefit from evidence-based interventions to reduce the need for involuntary sedation.
