Child and Adolescent Mental Health Repeat Visits to the Emergency Department: A Systematic Review

Factors associated with mental health representations to the emergency department within six months

BACKGROUND/OBJECTIVE

ED representation places a tremendous drain on resources with mental health (MH) representation among the most common. This study aimed to identify patient and clinical factors associated with 28-day and six-month ED MH representation of an index MH ED presentation.

METHOD

All MH related ED presentations from 1 January 2017 to 30 June 2019 were extracted from routinely collected administrative data. Cox regression and multinomial logistic regression models tested associations between patient characteristics and risk of representation.

RESULTS

For the 8,010 patients, 28-day and six-month representations were 8 % and 16 % respectively. Self-identifying with a MH problem at index presentation (28-day hazard ratio (HR) = 1.48, 95 % CI = 1.19-1.84; six-month HR = 1.52, 95 % CI = 1.29-1.78), leaving ED before completing treatment (28-day HR = 4.13, 95 % CI = 3.36-5.08; six-month HR = 2.52, 95 % CI = 2.12-2.99), no private health insurance (six-month HR = 1.34, 95 % CI = 1.08-1.66), and hospital admission within one year prior to index (six month MH-related admission vs non-MH, HR = 1.59, 95 % CI = 1.19-2.13) were associated with increased risk of representation. Being uninsured was associated with frequent six-month representation among adults aged 16-39 years (OR = 3.16, 95 %CI = 1.59-6.25).

CONCLUSION

Self-identifying with a MH problem, leaving ED prematurely, being uninsured and prior hospitalisation are areas for in-depth investigation for improved understanding of unplanned representations.

Factors associated with repeat emergency department visits for mental health care in adolescents: A scoping review

OBJECTIVES

The aim of this review was to identify factors associated with multiple visits to emergency department (ED) services for mental health care in adolescents.

METHODS

Electronic databases (MEDLINE, PsycINFO, Embase, CINAHL, Web of Science and ProQuest Dissertations & Thesis Global) were searched for evidence that presented an association between risk factors or correlates of multiple visits to the emergency departmental for mental health care by 10-24 year olds. High impact use was defined as at least one return ED visit for mental health care. Primary studies of any quantitative design were included, with no exclusions based on language or country and all possible risk factors were considered. Data were extracted and synthesised using quantitative methods; frequencies of positive, negative and null associations were summarised for categories of potential risk factors.

RESULTS

Sixty-five studies were included in the review. Most studies were from North America and reported a wide range of measures of high impact ED use, the most common being a binary indicator of multiple ED visits. Sex/gender and age were the most frequently reported risk factors. Measure of previous or concurrent access to mental health care was consistently positively associated with high impact use. Having private health insurance, compared with public or no insurance, was generally negatively associated with high impact use. Proxy measures of socioeconomic position (SEP) showed associations between lower SEP and more high impact use in a small number of studies. No other factors were consistently or uniformly associated with high impact use.

CONCLUSIONS

The review identified a substantial evidence base but due to the variability in study design and measurement of both risk factors and outcomes, no consistent risk factors emerged. More research is needed, particularly outside North America, using robust methods and high quality routinely collected data.

Impact of COVID-19 on Acute Care Hospitalizations for Suicidality

BACKGROUND AND OBJECTIVES

The coronavirus disease 2019 (COVID-19) pandemic contributed to the public health crisis for pediatric mental health. We characterized our local patient population presenting with suicidality or suicide attempts before and after the pandemic by examining: 1. frequencies of hospitalizations for suicidality to determine whether they differed by age, legal sex, race and ethnicity, or socioeconomic status; 2. average length of stay and discharge disposition; 3. 7-, 30-, and 365-day reutilization rates; and 4. admission trends during COVID-19 surges.

METHODS

Retrospective data between March 2018 and March 2022 was analyzed, including patients ages 10 to 17 years hospitalized for either suicidality or a suicide attempt at 1 freestanding tertiary care pediatric medical hospital in the Midwest. Encounters were divided into 2 categories on the basis of the COVID-19 pandemic: "Prelockdown" (March 1, 2018-March 12, 2020) and "postlockdown" (March 13, 2020-March 31, 2022). Patients were limited to 1 presentation pre- and postlockdown. We analyzed frequencies using means and SDs, categorical data using χ2 and Fisher's exact tests, and continuous data with t tests.

RESULTS

A total of 1017 encounters were included, stratified into pre- and postlockdown groups for analysis (909 encounters, 889 unique patients). There was a significant difference in 365-day reutilization pre- and postlockdown when analyzing re-presentation to the emergency department (P = .025) and hospital readmission (P = .006). Admissions incrementally increased after the COVID-19 alpha variants in September 2020 and again after the delta variant in August 2021.

CONCLUSIONS

The COVID-19 pandemic further intensified the already critical issue of pediatric mental health, demonstrating increased reutilization in the year after their initial presentation and an increase in admissions after the alpha variant.

Identifying patterns of substance use and mental health concerns among adolescents in an outpatient mental health program using latent profile analysis

Though mental health and substance use concerns often co-occur, few studies have characterized patterns of co-occurrence among adolescents in clinical settings. The current investigation identifies and characterizes these patterns among adolescents presenting to an outpatient mental health service in Ontario, Canada. Data come from cross-sectional standardized patient intake assessments from 916 adolescents attending an outpatient mental health program (January 2019-March 2021). Latent profile analysis identified patterns of substance use (alcohol, cannabis, (e-) cigarettes) and emotional and behavioral disorder symptoms. Sociodemographic and clinical correlates of these patterns were examined using multinomial regression. Three profiles were identified including: 1) low substance use and lower frequency and/or severity (relative to other patients in the sample) emotional and behavioral disorder symptoms (26.2%), 2) low substance use with higher emotional and behavioral disorder symptoms (48.2%), and 3) high in both (25.6%). Profiles differed in sociodemographic and clinical indicators related to age, gender, trauma, harm to self, harm to others, and service use. Experiences of trauma, suicide attempts, and thoughts of hurting others increased the odds of adolescents being in the profile high in both substance use and symptoms compared to other profiles. These findings further document the high rates of substance use in adolescents in mental health treatment and the profiles generally map onto three out of four quadrants in the adapted four-quadrant model of concurrent disorders, indicating the importance of assessing and addressing substance use in these settings.

Pediatric Psychiatric Emergencies

Pediatric psychiatric emergencies account for 15% of emergency department visits and are on the rise. Psychiatric diagnoses in the pediatric population are difficult to make, due to their variable presentation, but early diagnosis and treatment improve clinical outcome. Medical reasons for the patient's presentation should be explored. Both physical and emotional safety must be ensured. A multidisciplinary approach, utilizing local primary care and psychiatric resources, is recommended.

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

BACKGROUND

Family 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.

METHODS

Demographics, 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.

RESULTS

Emergency 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.

CONCLUSIONS

Police-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.

Youth Mobile Response and Stabilization Services: Factors Associated with Multiple Episodes of Care

Mobile response and stabilization services (MRSS) provide short-term, community-based, care to individuals in crisis. Minimal studies have explored which factors are associated with multiple episodes of MRSS care. We used a retrospective cohort design of MRSS electronic health records to explore demographic and clinical characteristics associated with multiple episodes of care among 2,641 youth ages 5-21 years old in New York, USA. Youth with multiple episodes of care (n = 585; 22.2%) were more likely to be non-Hispanic, have treatment histories including presenting problems related to adjustment, conduct, mood, or suicidal thoughts and behaviors, have high-level mental health visits, and more follow-up visits. Future research should examine the unmet needs of non-Hispanic populations and whether characteristics associated with multiple MRSS episodes are consistent across populations to inform procedures targeting unmet needs that prevent or minimize repeated use during crises.

Associations between outpatient treatment and the use of intensive psychiatric healthcare services

The current manuscript examines concurrent and longitudinal associations between the utilization of outpatient and intensive psychiatric services among Medicaid-enrolled youth. Using an administrative dataset of Medicaid claims from 2007 to 2017, youth were included if they were between the ages of 10-18 (M = 13.4, SD = 2.6) and had a psychiatric Medicaid claim (N = 33,590). Psychiatric services were coded as outpatient, emergency department (ED), inpatient, or residential based on Medicaid codes. Logistic regression analyses indicated that the receipt of even one outpatient visit significantly reduced the odds of having an ED, inpatient, and residential visit within 60-, 90-, and 120-day windows. Survival analyses indicated most youth did not have any ED, inpatient, or residential visit following their first outpatient visit. For remaining youth, having an outpatient visit significantly increased the risk of having an ED, inpatient, and residential visit following their initial appointment, which may suggest these youth are being triaged to a more appropriate level of care. Classification accuracy analyses indicated a cutoff of 2 outpatient visits yielded maximum accuracy in determining youth with ED, inpatient, and residential visits. Findings highlight use of outpatient-level services in reducing risk of more intensive service utilization.

Patterns of emergency department presentations for a youth mental health cohort: data-linkage cohort study

BACKGROUND

Primary youth mental health services in Australia have increased access to care for young people, yet the longer-term outcomes and utilisation of other health services among these populations is unclear.

AIMS

To describe the emergency department presentation patterns of a help-seeking youth mental health cohort.

METHOD

Data linkage was performed to extract Emergency Department Data Collection registry data (i.e. emergency department presentations, pattern of re-presentations) for a transdiagnostic cohort of 7024 youths (aged 12-30 years) who presented to mental health services. Outcome measures were pattern of presentations and reason for presentations (i.e. mental illness; suicidal behaviours and self-harm; alcohol and substance use; accident and injury; physical illness; and other).

RESULTS

During the follow-up period, 5372 (76.5%) had at least one emergency department presentation. The presentation rate was lower for males (IRR = 0.87, 95% CI 0.86-0.89) and highest among those aged 18 to 24 (IRR = 1.117, 95% CI 1.086-1.148). Almost one-third (31.12%) had an emergency department presentation that was directly associated with mental illness or substance use, and the most common reasons for presentation were for physical illness and accident or injury. Index visits for mental illness or substance use were associated with a higher rate of re-presentation.

CONCLUSIONS

Most young people presenting to primary mental health services also utilised emergency services. The preventable and repeated nature of many presentations suggests that reducing the ongoing secondary risks of mental disorders (i.e. substance misuse, suicidality, physical illness) could substantially improve the mental and physical health outcomes of young people.

Readmission of adolescent psychiatric patients to a specialised unit in Gauteng, South Africa

Background

Readmission rates to child and adolescent psychiatric units among the youth have been reported to be increasing.

Aim

The study aimed to determine the readmission rate and factors associated with readmission of adolescent psychiatric patients at a child and adolescent psychiatric unit.

Setting

A specialised psychiatric hospital in Gauteng province, South Africa.

Methods

This retrospective cohort study utilised data from the records of patients admitted to the adolescent inpatient unit over a period of five years. The cumulative incidence and incidence rate of readmission within one year of discharge from the index admission was calculated using survival analysis methods. Characteristics significantly associated with readmission were determined by applying the multivariable Cox proportional hazards regression model.

Results

Among the 189 patients included in the analysis, the cumulative incidence of readmission within one year of discharge was 17.5%. The incidence rate was 5.31 readmissions per 10 000 person-days. The final multivariable model showed that a diagnosis of schizophrenia (p = 0.015), a diagnosis of attention deficit hyperactivity disorder (p = 0.039), and coming from a child and youth care centre or temporary safe care (p = 0.018) increased the risk of readmission while having a medical condition (p = 0.008) reduced the risk.

Conclusion

Psychiatric diagnosis and residential care could be potential risk markers for readmission. Improving the collaboration between health and social services in residential care would be beneficial.

Contribution

Identifying factors that predispose adolescent psychiatric patients to readmission can inform and improve management and risk assessments.

Acute mental health service use in adolescents with suicidal thoughts and behaviours: Impact on outpatient care

INTRODUCTION

Youth with suicidal thoughts and behaviours often present to acute emergency care settings for assessment. Timely outpatient follow up may reduce return acute care visits. The primary aim of our study was to describe clinical and contextual differences between youth who do and do not use acute care once connected to outpatient services.

METHODS

A 24-month retrospective chart review of suicidal youth aged 13-16 (n = 45) presenting for outpatient mental health treatment. Youth who used acute services during the study period (ASU) or did not (non-ASU) were compared on demographic, risk profile, and mental health service use.

RESULTS

The mean age of participants was 14.6 years (73% female). Suicide risk profile at baseline did not differ between groups, but was significantly higher in ASU youth at 24 months. There were more youth in service at the end of the study period in the ASU group compared to the non-ASU group (11% vs 55%).

CONCLUSION

Youth who do continue to access acute services may be at higher risk of suicidality even after outpatient treatment. Although it is unclear whether this is linked to outpatient engagement, it raises further questions about this population and how they respond to community based mental healthcare.

Follow-up After Pediatric Mental Health Emergency Visits

OBJECTIVES

To examine how outpatient mental health (MH) follow-up after a pediatric MH emergency department (ED) discharge varies by patient characteristics and to evaluate the association between timely follow-up and return encounters.

METHODS

We conducted a retrospective study of 28 551 children aged 6 to 17 years with MH ED discharges from January 2018 to June 2019, using the IBM Watson MarketScan Medicaid database. Odds of nonemergent outpatient follow-up, adjusted for sociodemographic and clinical characteristics, were estimated using logistic regression. Cox proportional hazard models were used to evaluate the association between timely follow-up and risk of return MH acute care encounters (ED visits and hospitalizations).

RESULTS

Following MH ED discharge, 31.2% and 55.8% of children had an outpatient MH visit within 7 and 30 days, respectively. The return rate was 26.5% within 6 months. Compared with children with no past-year outpatient MH visits, those with ≥14 past-year MH visits had 9.53 odds of accessing follow-up care within 30 days (95% confidence interval [CI], 8.75-10.38). Timely follow-up within 30 days was associated with a 26% decreased risk of return within 5 days of the index ED discharge (hazard ratio, 0.74; 95% CI, 0.63-0.91), followed by an increased risk of return thereafter.

CONCLUSIONS

Connection to outpatient care within 7 and 30 days of a MH ED discharge remains poor, and children without prior MH outpatient care are at highest risk for poor access to care. Interventions to link to outpatient MH care should prioritize follow-up within 5 days of an MH ED discharge.

Mental Health Revisits at US Pediatric Emergency Departments

Importance

Pediatric emergency department (ED) visits for mental health crises are increasing. Patients who frequently use the ED are of particular concern, as pediatric mental health ED visits are commonly repeat visits. Better understanding of trends and factors associated with mental health ED revisits is needed for optimal resource allocation and targeting of prevention efforts.

Objective

To describe trends in pediatric mental health ED visits and revisits and to determine factors associated with revisits.

Design, Setting, and Participants

In this cohort study, data were obtained from 38 US children's hospital EDs in the Pediatric Health Information System between October 1, 2015, and February 29, 2020. The cohort included patients aged 3 to 17 years with a mental health ED visit.

Exposures

Characteristics of patients, encounters, hospitals, and communities.

Main Outcomes and Measures

The primary outcome was a mental health ED revisit within 6 months of the index visit. Trends were assessed using cosinor analysis and factors associated with time to revisit using mixed-effects Cox proportional hazards regression.

Results

There were 308 264 mental health ED visits from 217 865 unique patients, and 13.2% of patients had a mental health revisit within 6 months. Mental health visits increased by 8.0% annually (95% CI, 4.5%-11.4%), whereas all other ED visits increased by 1.5% annually (95% CI, 0.1%-2.9%). Factors associated with mental health ED revisits included psychiatric comorbidities, chemical restraint use, public insurance, higher area measures of child opportunity, and presence of an inpatient psychiatric unit at the presenting hospital. Patients with psychotic disorders (hazard ratio [HR], 1.42; 95% CI, 1.29-1.57), disruptive or impulse control disorders (HR, 1.36; 95% CI, 1.30-1.42), and neurodevelopmental disorders (HR, 1.22; 95% CI, 1.14-1.30) were more likely to revisit. Patients with substance use disorders (HR, 0.60; 95% CI, 0.55-0.66) were less likely to revisit.

Conclusions and Relevance

Markers of disease severity and health care access were associated with mental health revisits. Directing hospital and community interventions toward identified high-risk patients is needed to help mitigate recurrent mental health ED use and improve mental health care delivery.

Paediatric frequent use of emergency medical services: a systematic review

BACKGROUND

Frequent use of emergency medical services (EMS) is recognised to be a global phenomenon, although paediatric frequent use is poorly understood. This systematic review aimed to understand how paediatric frequent use of EMS is currently defined, identify factors associated with paediatric frequent use of EMS and determine effectiveness of interventions for paediatric patients who frequently use EMS.

METHODS

Four electronic databases (Medline, CINAHL, Web of Science and PsycINFO) were searched to September 2022 for primary, peer-reviewed research studies published in English from January 2000. Studies were included that examined frequent use (>1 contact during study period) of EMS or other services with arrival via EMS. Paediatric patients were defined as <18 years of age or otherwise defined by study authors as paediatric/adolescent/children. Data were extracted using a structured proforma, and quality was assessed using the Standard Quality Assessment Criteria for Quantitative Studies but did not influence inclusion decisions. Data were presented using narrative synthesis.

RESULTS

The search resulted in 4172 unique references, with 12 papers included in the review from 7 countries. Four were EMS studies, and eight Emergency Department with arrival via EMS. All studies used retrospective designs, with no interventional studies identified. Paediatric frequent EMS users were more likely to use services for medical reasons rather than trauma, including respiratory complaints, mental health and seizures, but data on gender and ethnicity were inconclusive and silent on socioeconomic status. There was no consistency in definitions of either a paediatric patient or of frequent use.

CONCLUSION

The broad range of reasons for frequent use suggests that a single intervention is unlikely to be effective at addressing the causes of frequent use. There is a need for further research to better identify the underlying reasons for frequent EMS use among paediatric patients and to develop interventions in this population.

Factors Associated With Police Bringing Children to a Psychiatric Emergency Room

OBJECTIVE

Sensational headlines describing police entanglements with young children have prompted questions about how often these incidents occur and why. The authors of this cross-sectional study examined the factors associated with police versus nonpolice arrivals to the psychiatric emergency room and those predicting subsequent police arrivals.

METHODS

Electronic medical records of children ages 5.0-12.9 years brought to a comprehensive psychiatric emergency program (CPEP) at a university hospital were reviewed to determine whether a child was brought by police ("police arrival") in response to a 911 call by school personnel, a mental health or other medical professional, or a caregiver. Extracted data included the child's age, sex, race-ethnicity, family makeup, insurance status, arrival status, referral source, diagnosis, disposition, treatment, number of CPEP and police encounters, and occurrences of aggression and suicidality. Multilevel and ordinary logistic regression models were used to identify factors associated with a first and subsequent police arrival.

RESULTS

Of 339 children with CPEP encounters from September 2017 to April 2018, 103 (30%) had had at least one police arrival. Children brought by police were more likely than peers brought by caregivers to be Black or Latinx, have Medicaid, come from families without two parents, and have aggressive outbursts or suicidal behavior. Results from multilevel logistic regression indicated that aggressive outbursts and suicidality were most significantly and consistently associated with experiencing both a first and subsequent police arrival.

CONCLUSIONS

Clinical and sociodemographic differences in police arrivals highlight the need for a comprehensive systems approach for children, especially marginalized youths, who need psychiatric emergency care.

Presentations to the Emergency Department for Problems Related to Mental Health: Sex Differences in Adolescents

BACKGROUND

Adolescents aged sixteen to eighteen years are mostly treated in adult emergency departments. In a study at our tertiary adult emergency department (ED) at the University Hospital in Bern (Inselspital), Switzerland, we found that adolescents significantly more often present with psychiatric problems than adults. The study at hand aimed to characterise those adolescents presenting to the ED triaged with a chief complaint regarding mental health. Furthermore, the goal was to assess sex differences in terms of diagnosis, suicidal ideation, substance use, as well as social impact.

METHODS

We conducted a single-centre, retrospective review of presentations to our adult ED related to the mental health of adolescents aged 16 to 18 years, covering the period from January 2013 to July 2017. Anonymised data were extracted from medical reports referring to the ED visits that were triaged as mental-health-related, and we assessed these for diagnosis, acute and previous suicidal ideation, history of self-harm, external aggression, substance use and social problems. We focused on patient characterisation and defining sex differences.

RESULTS

Data were analysed for a total of 612 consultations by adolescents who presented to our ED with problems related to mental health. Women accounted for 61.1% of cases. The most frequent diagnoses were reactions to severe stress and adjustment disorders (19.1%), followed by alcohol use disorders (17.6%), intentional self-harm (17.3%), and affective disorders (13.7%). Males had lower odds for intentional self-harm (OR 0.10, 95% 0.05-0.21, p < 0.001) as well as disorders of personality and behaviour (OR 0.09, 95% 0.21-0.37, p < 0.001), whereas they had higher odds of being admitted due to use of alcohol (OR 2.51, 95% 1.65-3.83, p < 0.001). Of all cases, 31.7% reported acute suicidal ideation, with a significantly lower odds ratio in males (OR 0.58, 95% 0.41-0.84, p = 0.004). The most common source for referral to the ED was family members (25.2%). Males had twice the odds of reporting alcohol consumption as well as use of cannabis (in both cases p < 0.001). In 27.9% of all cases, familial problems were reported, with males having significantly lower odds of being exposed to these (OR 0.64, 95% 0.44-0.94, p = 0.021), whereas they had higher odds of reporting educational problems (OR 1.68, 95% 1.04-2.72, p = 0.035).

CONCLUSIONS

Adolescents aged sixteen to eighteen years presenting to the ED with problems related to mental health are an important subgroup of ED presentations and should be thoroughly assessed for suicidal ideation, substance use, as well as familial and educational problems. Assessment and establishment of post-ED care are of particular importance in this vulnerable patient group.

Characteristics of a Pediatric Emergency Psychiatric Telephone Triage Service

OBJECTIVES

Caregivers of youth in psychiatric crisis often seek treatment from hospital emergency departments (EDs) as their first point of entry into the mental health system. Emergency departments have struggled over the last decade with growing numbers and now, because of the pandemic, have experienced a deluge of mental health crises. As one approach to divert unnecessary ED admissions, pediatric emergency psychiatric telephone triage services have been created. This study aimed to define the characteristics and utilization of a pediatric triage service and to examine clinician documentation of calls to identify the assessment of risk and disposition.

METHODS

This study included 517 youth (2-18 years; mean, 12.42 years; SD, 3.40 years) who received triage services in the winter of 2 consecutive years. Triage calls were received from caregivers (>75%), schools (17.0%), and providers (6.6%) regarding concerns, including suicidal ideation (28.6%), school issues (28.6%), and physical aggression (23.4%).

RESULTS

Dispositions were for acute, same-day evaluation (9.7%), direct care service (28.8%), further evaluation (within 48-72 hours, 40.0%), and resource/service update information (21.5%). Findings revealed that most clinical concerns were referred for further evaluation. Both adolescent females and males were referred for emergency evaluations at high rates.

CONCLUSIONS

A dearth of information on pediatric crisis telephone triage services exists; thus, developing an evidence base is an important area for future work. This information assists not only in our understanding of which, why, and how many youths are diverted from the ED but allows us to extrapolate significant costs that have been saved because of the utilization of the triage service.

Emergency Department Use by Children and Youth with Mental Health Conditions: A Health Equity Agenda

There are growing concerns regarding the referral of children and youth with mental health conditions to emergency departments (EDs). These focus on upward trends in utilization, uncertainty about benefits and negative effects of ED visits, and inequities surrounding this form of care. A review was conducted to identify and describe available types of data on ED use. The authors' interpretation of the literature is that it offers compelling evidence that children and youth in the U.S. are being sent to EDs for mental health conditions at increasing rates for reasons frequently judged as clinically inappropriate. As a major health inequity, it is infrequent that such children and youth are seen in EDs by a behavioral health professional or receive evidence-based assessment or treatment, even though they are kept in EDs far longer than those seen for reasons unrelated to mental health. The rate of increase in these referrals to EDs appears much greater for African American and Latinx children and youth than White children and is increasing for the publicly insured and uninsured while decreasing for the privately insured. A comprehensive set of strategies are recommended for improving healthcare quality and health equity. A fact sheet is provided for use by advocates in pressing this agenda.

Emergency Department Initiated Mental Health Interventions for Young People: A Systematic Review

OBJECTIVE

Young people (10-24 years old) with mental health concerns are increasingly presenting to hospital emergency departments (EDs). The purpose of this review was to identify the core components and outcomes of mental health interventions for young people that are initiated in the ED, such that they are delivered in the ED and/or by ED health workers.

METHODS

Six electronic databases were systematically searched. Primary peer-reviewed qualitative or quantitative studies describing an ED-initiated mental health intervention for young people published between 2009 and 2020 were included.

RESULTS

Nine studies met the inclusion criteria. The included studies demonstrated that compared with traditional ED care, ED-initiated mental health interventions lead to improved efficiency of care and decreased length of stay, and a core component of this care was its delivery by allied health practitioners with mental health expertise. The studies were limited by focusing on service efficiencies rather than patient outcomes. Further limitations were the exclusion of young people with complex mental health needs and/or comorbidities and not measuring long-term positive mental health outcomes, including representations and whether young people were connected with community health services.

CONCLUSIONS

This systematic review demonstrated that ED-initiated mental health interventions result in improved service outcomes, but further innovation and robust evaluation are required. Future research should determine whether these interventions lead to better clinical outcomes for young people and staff to inform the development of best practice recommendations for ED-initiated mental health care for young people presenting to the ED.

Returning to the emergency department: a retrospective analysis of mental health re-presentations among young people in New South Wales, Australia

OBJECTIVES

This study aimed to describe mental health emergency department (ED) presentations among young people aged 8-26 years in New South Wales, Australia, and to identify key characteristics associated with higher risk of ED mental health re-presentation.

DESIGN, SETTING AND PARTICIPANTS

Retrospective analysis of linked ED data records for mental health presentations between 1 January 2015 and 30 June 2018.

MAIN OUTCOME MEASURES

The main outcome was the total number of mental health ED re-presentations within 1 year, following initial presentation. Count regression models were fitted to estimate factors associated with higher likelihood of re-presentations.

RESULTS

Forty thousand two hundred and ninety patients were included in the analyses, and 9713 (~25%) re-presented during the following year; 1831 (20%) presented at least three times. On average, patients re-presented 0.61 times per 365 person-days, with average time until first re-presentation of ~92 days but greatest risk of re-presentation within first 30-60 days. Young people with self-harm or suicidal diagnoses at initial presentation were more likely to re-present. Re-presentations were highest among young people <15 years (IRR 1.18 vs ≥20 years old), female (IRR=1.13 vs male), young people residing outside of major cities (IRR 1.08 vs major cities) and Aboriginal and Torres Strait Islander young people (IRR 1.27 vs non-Indigenous).

CONCLUSIONS

ED mental health re-presentation is high among young people. We demonstrate factors associated with re-presentation that EDs could target for timely, high-quality care that is youth friendly and culturally safe, with appropriate referral pathways into community-based primary and mental healthcare services.

Are There Differences in Pediatric Psychiatric Emergency Department Patients Related to Utilization Frequency?

OBJECTIVES

The increasing frequency of visits to the pediatric psychiatric emergency department in the United States signals a need for a better understanding of factors contributing to more frequent utilization. This study examined characteristics of patients associated with higher utilization of the pediatric psychiatric emergency department to increase understanding of this group of patients.

METHODS

This was a retrospective observational study. Data were abstracted from the electronic medical record system from January 2012 to December 2017 for patients with a completed mental health consultation. There were 8504 total encounters for 6950 unique patients during this period. Analyses were conducted to test associations between maximum number of visits in any 1-year period for each patient and demographic and clinical factors.

RESULTS

Younger age was independently associated with greater mean number of visits within any 1 year. No independent associations were found between maximum number of visits within 1 year and sex, race, language, insurance type, distance from emergency department, time spent in the emergency department, or reason for visit.

CONCLUSIONS

The greater emergency department use by younger children found in this study may be an indicator of insufficient treatment at other levels of care. Additional research examining more demographic variables and demographic characteristics in greater detail is needed to fully characterize the most frequent users of costly pediatric psychiatric emergency department care.

Heart Rate Variability and Its Ability to Detect Worsening Suicidality in Adolescents: A Pilot Trial of Wearable Technology

OBJECTIVE

Suicide is the 2nd leading cause of death in adolescence, and acute pediatric mental health emergency department (ED) visits have doubled in the past decade. The objective of this study was to evaluate physiologic parameters relationship to suicide severity.

METHODS

This was a prospective, observational study from April 2018 thru November 2019 in a tertiary care pediatric emergency department (ED) and inpatient pediatric psychiatric unit enrolling acutely suicidal adolescent patients. Patients wore a wrist device that used photoplethysmography for 7 days during their acute hospitalization to measure heart rate variability (HRV). During that time, Columbia Suicide Severity Scores (CSSRS) were assessed at 3 time points.

RESULTS

There was complete device data and follow-up for 51 patients. There was an increase in the high frequency (HF) component of HRV in patients that had a 25% or greater decrease in their CSSRS (mean difference 11.89 ms/ Hz ; p-value 0.005). Patients with a CSSRS≥15 on day of enrollment had a lower, although not statistically significant, HF component (mean difference -8.34 ms/ Hz; p-value 0.071).

CONCLUSION

We found an inverse correlation between parasympathetic activity measured through the HF component and suicidality in an acutely suicidal population of adolescents. Wearable technology may have the ability to improve outpatient monitoring for earlier detection and intervention.

Heart Rate Variability Duration: Expanding the Ability of Wearable Technology to Improve Outpatient Monitoring?

Heart rate variability (HRV) evaluates beat-to-beat interval (BBI) differences and is a suggested marker of the autonomic nervous system with diagnostic/monitoring capabilities in mental health; especially parasympathetic measures. The standard duration for short-term HRV analysis ranges from 24 h down to 5-min. However, wearable technology, mainly wrist devices, have large amounts of motion at times resulting in need for shorter duration of monitoring. The objective of this study was to evaluate the correlation between 1 and 5 min segments of continuous HRV data collected simultaneously on the same patient. Subjects wore a patch electrocardiograph (Cardea Solo, Inc.) over a 1-7 day period. For every consecutive hour the patch was worn, we selected a 5-min, artifact-free electrocardiogram segment. HRV metric calculation was performed to the entire 5-min segment and the first 1-min from this same 5-min segment. There were 492 h of electrocardiogram data collected allowing calculation of 492 5 min and 1 min segments. 1 min segments of data showed good correlation to 5 min segments in both time and frequency domains: root mean square of successive difference (RMSSD) (R = 0.92), high frequency component (HF) (R = 0.90), low frequency component (LF) (R = 0.71), and standard deviation of NN intervals (SDNN) (R = 0.63). Mental health research focused on parasympathetic HRV metrics, HF and RMSSD, may be accomplished through smaller time windows of recording, making wearable technology possible for monitoring.

A Three-Step, Single Session Therapy Intervention for COVID-Related Anxiety in a Pediatric Emergency Department

The novel Coronavirus disease (COVID-19) pandemic has led to increases in anxiety and depression, and mental health-related emergency department visits remain frequent despite overall changes in ED utilization. Here, we present a case of COVID-related anxiety and demonstrate the utility of a brief, single-session therapy intervention delivered in the ED. The growing mental health burden of COVID-19 suggests that pediatric health care providers will treat patients with COVID-related anxiety during this pandemic. This case demonstrates a common presentation of somatization of anxiety and outlines a three-step, cognitive-behavioral intervention that can be particularly effective in treating COVID-related anxiety in the context of a single ED or medical visit.

Young children with psychiatric complaints in the pediatric emergency department

INTRODUCTION

Children are increasingly diagnosed with mental illnesses and self-harm behaviors. They present frequently to the emergency department (ED) for evaluation. The aim of this study is to describe the youngest children in the ED with psychiatric issues.

METHODS

This is a retrospective chart review of all consecutive children less than 10 years of age with a psychiatric complaint who received a psychiatric consultation in the pediatric emergency department in the last four years.

RESULTS

The number of children with psychiatric issues increased over the study period. The ED length of stay also increased. Violent behavior and aggression were the most common chief complaints, and some children required chemical or physical restraint in the ED. Many children had pre-existing psychiatric issues and a history of adverse childhood experiences. Half of patients were deemed safe for discharge home by psychiatric consultation.

CONCLUSION

The number of young children with psychiatric complaints presenting to the ED has increased. However, a large number are found to be stable for discharge home. Increase in urgent outpatient psychiatric resources could help decrease ED utilization.

Forty years of emergency medicine research: Uncovering research themes and trends through topic modeling

STUDY OBJECTIVE

Topic identification can facilitate knowledge curation, discover thematic relationships, trends, and predict future direction. We aimed to determine through an unsupervised, machine learning approach to topic modeling the most common research themes in emergency medicine over the last 40 years and summarize their trends and characteristics.

METHODS

We retrieved the complete reference entries including article abstracts from Ovid for all original research articles from 1980 to 2019 within emergency medicine for six widely-cited journals. Abstracts were processed through a natural language pipeline and analyzed by a latent Dirichlet allocation topic modeling algorithm for unsupervised topic discovery. Topics were further examined through trend analysis, word associations, co-occurrence metrics, and two-dimensional embeddings.

RESULTS

We retrieved 47,158 articles during the defined time period that were filtered to 20,528 articles for further analysis. Forty topics covering methodologic and clinical areas were discovered. These topics separated into distinct clusters when embedded in two-dimensional space and exhibited consistent patterns of interaction. We observed the greatest increase in popularity in research themes involving risk factors (0.4% to 5.2%), health utilization (1.2% to 5.0%), and ultrasound (0.7% to 3.3%), and a relative decline in research involving basic science (8.9% to 1.1%), cardiac arrest (6.5% to 2.2%), and vitals (6.3% to 1.3%) over the past 40 years. Our data show only very modest growth in mental health and substance abuse research (1.0% to 1.6%), despite ongoing crises.

CONCLUSIONS

Topic modeling via unsupervised machine learning applied to emergency medicine abstracts discovered coherent topics, trends, and patterns of interaction.

Psychiatric Readmission of Children and Adolescents: A Systematic Review and Meta-Analysis

OBJECTIVE

To investigate predictors of psychiatric hospital readmission of children and adolescents, a systematic review and meta-analysis was conducted.

METHODS

Following PRISMA statement guidelines, a systematic literature search of articles published between 1997 and 2018 was conducted in PubMed/MEDLINE, Google Scholar, and PsycINFO for original peer-reviewed articles investigating predictors of psychiatric hospital readmission among youths (<18 years old). Effect sizes were extracted and combined by using random-effects meta-analysis. Covariates were investigated with meta-regression and subgroup analyses.

RESULTS

Thirty-three studies met inclusion criteria, containing information on 83,361 children and adolescents, of which raw counts of readmitted vs. non-readmitted youths were available for 76,219. Of these youths, 13.2% (N=10,076) were readmitted. The mean±SD study follow-up was 15.9±15.0 months, and time to readmission was 13.1±12.8 months. Readmission was associated with, but not limited to, suicidal ideation at index hospitalization (pooled odds ratio [OR_pooled]=2.35, 95% confidence interval [CI]=1.64-3.37), psychotic disorders (OR_pooled=1.87, 95% CI=1.53-2.28), prior hospitalization (OR_pooled=2.51, 95% CI=1.76-3.57), and discharge to residential treatment (OR_pooled=1.84, 95% CI=1.07-3.16). There was evidence of moderate study bias. Prior investigations were methodologically and substantively heterogeneous, particularly for measurement of family-level factors.

CONCLUSIONS

Interventions to reduce child psychiatric readmissions should place priority on youths with indicators of high clinical severity, particularly with a history of suicidality, psychiatric comorbidity, prior hospitalization, and discharge to residential treatment. Standardization of methods to determine prevalence rates of readmissions and their predictors is needed to mitigate potential biases and inform a national strategy to reduce repeated child psychiatric hospital readmissions.

Understanding parent-reported factors that influence children and young people's anxiety and depression presentations to emergency departments: A multi-site study

OBJECTIVE

Victorian ED data show increased presentations for anxiety and depression in children. We aimed to determine parent-reported factors contributing to these presentations.

METHODS

Qualitative study with parents of children and young people aged 0-17 years who attended one of four EDs across Victoria between October 2017 and September 2018 and received a primary diagnosis of anxiety or depression (excluding self-harm or suicide attempt). Eligible parents completed semi-structured phone interviews, which were audio-recorded and transcribed. Transcripts were coded and qualitatively analysed using thematic analysis.

RESULTS

Seventy parents completed interviews. The average age of children and young people was 14 years (standard deviation 2.4) and 63% (n = 44) identified as female. Thirty (43%) children received a primary diagnosis of depression, compared to 40 (57%) children who received a primary diagnosis of anxiety. The majority of respondents were mothers (n = 59; 84%). Key themes as to why families presented to EDs included: listening to trusted professionals, desperation, a feeling of no alternative, respecting their child's need to feel safe and to rule out a potentially serious medical condition.

CONCLUSIONS

Parents bring their children to the ED for many reasons. Policy makers, managers and clinicians should work with parents to develop alternative approaches that provide families with community-based support, particularly for younger children and after hours, in order to provide an appropriate source of care for children and young people with anxiety and depression.

Assessing the Quality Measure for Follow-up Care After Children's Psychiatric Hospitalizations

OBJECTIVES

Medicaid and Children's Health Insurance Program plans publicly report quality measures, including follow-up care after psychiatric hospitalization. We aimed to understand failure to meet this measure, including measurement definitions and enrollee characteristics, while investigating how follow-up affects subsequent psychiatric hospitalizations and emergency department (ED) visits.

METHODS

Administrative data representing Alabama's Children's Health Insurance Program from 2013 to 2016 were used to identify qualifying psychiatric hospitalizations and follow-up care with a mental health provider within 7 to 30 days of discharge. Using relaxed measure definitions, follow-up care was extended to include visits at 45 to 60 days and visits to a primary care provider. Logit regressions estimated enrollee characteristics associated with follow-up care and, separately, the likelihood of subsequent psychiatric hospitalizations and/or ED visits within 30, 60, and 120 days.

RESULTS

We observed 1072 psychiatric hospitalizations during the study period. Of these, 356 (33.2%) received follow-up within 7 days and 566 (52.8%) received it within 30 days. Relaxed measure definitions captured minimal additional follow-up visits. The likelihood of follow-up was lower for both 7 days (-18 percentage points; 95% confidence interval [CI] -26 to -10 percentage points) and 30 days (-26 percentage points; 95% CI -35 to -17 percentage points) regarding hospitalization stays of ≥8 days. Meeting the measure reduced the likelihood of subsequent psychiatric hospitalizations within 60 days by 3 percentage points (95% CI -6 to -1 percentage point).

CONCLUSIONS

Among children, receipt of timely follow-up care after a psychiatric hospitalization is low and not sensitive to measurement definitions. Follow-up care may reduce the need for future psychiatric hospitalizations and/or ED visits.

Characterizing behavioral health-related emergency department utilization among children with Medicaid: Comparing high and low frequency utilizers

While the frequency of children's behavioral health (BH)-related visits to the emergency department (ED) is rising nationwide, few studies have examined predictors of high rates of ED use. This study examines Florida Medicaid claims (2011-2012) for children age 0-18 who were seen in an emergency department (ED) for behavioral health (BH) conditions. A logistic regression model was used to explore factors associated with frequent ED use and patterns of psychotropic medication utilization. The majority (95%) of patients with at least one BH-related ED visit had three or fewer of these visits, but 5% had four or more. Seventy-four percent of ED visits were not associated with psychotropic medication, including over half (54%) of visits for attention deficit hyperactivity disorder (ADHD). Frequent ED use was higher among older children and those with substance use disorders. The implementation of interventions that reduce non-emergent ED visits through the provision of care coordination, social work services, and/or the use of community health workers as care navigators may address these findings.

Trends in Psychiatric Emergency Department Visits Among Youth and Young Adults in the US

BACKGROUND

Visits to the emergency department (ED) for psychiatric purposes are an indicator of chronic and acute unmet mental health needs. In the current study, we examined if psychiatric ED visits among individuals 6 to 24 years of age are increasing nationwide.

METHODS

ED data came from the 2011-2015 National Hospital Ambulatory Medical Care Survey, a national survey of ED visits across the United States. Psychiatric ED visits were identified by using the International Classification of Diseases, Ninth Revision and reason-for-visit codes. Survey-weighted logistic regression analyses were employed to examine trends in as well as correlates of psychiatric ED visits. Data from the US Census Bureau were used to examine population rates.

RESULTS

Between 2011 and 2015, there was a 28% overall increase (from 31.3 to 40.2) in psychiatric ED visits per 1000 youth in the United States. The largest increases in psychiatric ED visits per 1000 US youth were observed among adolescents (54%) and African American (53%) and Hispanic patients (91%). A large increase in suicide-related visits (by 2.5-fold) was observed among adolescents (4.6-11.7 visits per 1000 US youth). Although psychiatric ED visits were long (51% were ≥3 hours in length), few (16%) patients were seen by a mental health professional during their visit.

CONCLUSIONS

Visits to the ED for psychiatric purposes among youth are rising across the United States. Psychiatric expertise and effective mental health treatment options, particular those used to address the rising suicide epidemic among adolescents, are needed in the ED.

Family Factors and Repeat Pediatric Emergency Department Visits for Mental Health: A Retrospective Cohort Study

OBJECTIVES

Approximately 45% of youth presenting to the emergency department (ED) for mental health (MH) concerns will have a repeat ED visit. Since youth greatly depend on their caregivers to access MH services, the objective of this study was to determine if family characteristics were associated with repeat ED visits.

METHODS

A retrospective cohort study of youth aged 6-18 years (62% female) treated at a tertiary pediatric ED for a discharge diagnosis related to MH was conducted. Data were gathered from medical records, telephone interviews, and questionnaires. Family factor contribution was analyzed using a multivariable logistic regression model controlling for demographic, clinical and service utilization factors. Variables associated with earlier and more frequent visits were determined using cox regression and negative binomial regression.

RESULTS

Of 266 participants, 70 (26%) had a repeat visit. While caregiver history of MH treatment decreased the odds of having a repeat ED visit, family functioning and perceived family burden were not associated with repeat visits. Post-visit MH services, prior psychiatric hospitalization, higher severity of symptoms, and living closer to the hospital increased the odds of repeat visits.

CONCLUSIONS

This study examined the contribution of multiple family factors in predicting repeat MH visits to the ED. Results suggest caregiver characteristics may impact the decision to return. Healthcare providers should therefore consider caregiver and youth service utilization factors to inform patient management and discharge planning.

Evaluation and Management of Psychiatric Emergencies in Children

Mental illness among children and adolescents is an increasing burden, projected to become one of the world's leading disabilities in near future. A dearth of specialized services and personnel to provide optimal care affects the disease burden, prevalence, health care services, and health care costs. The increasing demand weighs down on generalized systems of care such as emergency department (ED) services, in which the lack of specific training, personnel, and specialized protocols tends to prolong length of stay, recidivism, and suboptimal care. This article reviews outcomes and trends of overburdened ED systems in the context of pediatric mental health care management, guidelines of care, and strategies to manage common pediatric mental health emergencies and expand services within the ED. [Pediatr Ann. 2018;47(8):e328-e333.].

Current Pediatric Emergency Department Innovative Programs to Improve the Care of Psychiatric Patients

Emergency departments (EDs) across North America have become a safety net for patients seeking mental health (MH) services. The prevalence of families seeking treatment of children in MH crisis has become a national emergency. To address MH access and improve quality and efficient management of children with MH conditions, the authors describe ED projects targeting this vulnerable population. Five North American health care systems volunteered to feature projects that seek to reduce ED visits and/or improve the care of MH patients: Allina Health, Nationwide Children's Hospital, Children's Hospital of Eastern Ontario, Connecticut Children's Medical Center, and Rhode Island Hospital.

An Emergency Department Clinical Pathway for Children and Youth with Mental Health Conditions

Children and youth presenting to the emergency department with mental health concerns present a challenge for clinicians and system capacity. Addressing a significant system gap and sparse strategies in the literature, representative leaders from hospital and community agencies developed a novel pathway to guide efficient and doable risk assessment and ensure timely transition to appropriate community mental health services. This article describes and reflects on our innovative Emergency Department Clinical Pathway for Children and Youth with Mental Health Conditions that bridges traditional barriers between hospital and community settings to address mental health needs for this population.

Evaluating mental health service use during and after emergency department visits in a multisite cohort of Canadian children and youth

Objectives

The goal of this study was to examine the mental health needs of children and youth who present to the emergency department (ED) for mental health care and to describe the type of, and satisfaction with, follow-up mental health services accessed.

Methods

A 6-month to 1.5-year prospective cohort study was conducted in three Canadian pediatric EDs and one general ED, with a 1-month follow-up post-ED discharge. Measures included 1) clinician rating of mental health needs, 2) patient and caregiver self-reports of follow-up services, and 3) interviews regarding follow-up satisfaction. Data analysis included descriptive statistics and the Fisher’s exact test to compare sites.

Results

The cohort consisted of 373 children and youth (61.1% female; mean age 15.1 years, 1.5 standard deviation). The main reason for ED presentations was a mental health crisis. The three most frequent areas of need requiring action were mood (43.8%), suicide risk (37.4%), and parent-child relational problems (34.6%). During the ED visit, 21.6% of patients received medical clearance, 40.9% received a psychiatric consult, and 19.4% were admitted to inpatient psychiatric care. At the 1-month post-ED visit, 84.3% of patients/caregivers received mental health follow-up. Ratings of service recommendations were generally positive, as 60.9% of patients obtained the recommended follow-up care and 13.9% were wait-listed.

Conclusions

Children and youth and their families presenting to the ED with mental health needs had substantial clinical morbidity, were connected with services, were satisfied with their ED visit, and accessed follow-up care within 1-month with some variability.
