Association between preferred language and use of mental health services among home care recipients with schizophrenia spectrum and other psychotic disorders: A retrospective cohort study in Ontario, Canada, 2010 to 2015

Language is an important demographic factor that may impact patients’ interactions with the healthcare system. This may become more apparent for individuals with a mental illness. The objective of this study was to evaluate whether individual language was associated with the use of inpatient and outpatient psychiatric services among home care recipients with schizophrenia spectrum and other psychotic disorders. We conducted a population-based retrospective cohort study using health administrative data. The study population included all individuals aged 18–105 with schizophrenia spectrum and other psychotic disorders, identified via a validated algorithm, who were receiving home care in Ontario, Canada between January 1, 2010 and December 31, 2015. Home care data was used to identify patients’ primary language, categorized as Anglophone, Francophone, or Allophone. Mental health service use was evaluated over a one-year period following their first home care assessment in the study period and included the rate of outpatient psychiatrist visits and mental health-related emergency department (ED) visits and hospitalizations. Multivariable regression evaluated the association between primary language and mental health service use. The cohort consisted of 9,436 patients (85.8% Anglophones, 3.3% Francophones, 11.0% Allophones). Mental health service use was low among all linguistic groups during the one-year study period, with 53.4% with no outpatient psychiatrist visits and 83.3% and 83.0% with no mental health-related hospitalizations or ED visits, respectively. Francophones had a higher rate of mental health-related hospitalizations compared to Anglophones (adjusted relative risk = 1.36, 95% confidence interval 1.02–1.80), with no differences in hospitalization rates between Allophones and Anglophones. Language was not associated with the rate of outpatient psychiatrist visits or mental health-related ED visits. Mental health service use among homecare patients with schizophrenia spectrum and other psychotic disorders was low. While Francophones had a higher hospitalization rate than Anglophones, language was otherwise not associated with mental health service use.

A Retrospective Cohort Analysis of Mental Health-Related Emergency Department Visits Among Veterans and Non-Veterans Residing in Ontario, Canada: Une analyse de cohorte rétrospective des visites au service d'urgence liées à la santé mentale parmi les vétérans et non-vétérans résidant en Ontario, Canada.

Emergency departments (EDs) are a vital part of healthcare systems, at times acting as a gateway to community-based mental health (MH) services. This may be particularly true for veterans of the Royal Canadian Mounted Police who were released prior to 2013 and the Canadian Armed Forces, as these individuals transition from federal to provincial healthcare coverage on release and may use EDs because of delays in obtaining a primary care provider. We aimed to estimate the hazard ratio (HR) of MH-related ED visits between veterans and non-veterans residing in Ontario, Canada: (1) overall; and by (2) sex; and (3) length of service. This retrospective cohort study used administrative healthcare data from 18,837 veterans and 75,348 age-, sex-, geography-, and income-matched non-veterans residing in Ontario, Canada between April 1, 2002, and March 31, 2020. Anderson-Gill regression models were used to estimate the HR of recurrent MH-related ED visits during the period of follow-up. Sex and length of service were used as stratification variables in the models. Veterans had a higher adjusted HR (aHR) of MH-related ED visits than non-veterans (aHR, 1.97, 95% CI, 1.70 to 2.29). A stronger effect was observed among females (aHR, 3.29; 95% CI, 1.96 to 5.53) than males (aHR, 1.78; 95% CI, 1.57 to 2.01). Veterans who served for 5-9 years had a higher rate of use than non-veterans (aHR, 3.76; 95% CI, 2.34 to 6.02) while veterans who served for 30+ years had a lower rate compared to non-veterans (aHR, 0.60; 95% CI, 0.42 à 0.84). Rates of MH-related ED visits are higher among veterans overall compared to members of the Ontario general population, but usage is influenced by sex and length of service. These findings indicate that certain subpopulations of veterans, including females and those with fewer years of service, may have greater acute mental healthcare needs and/or reduced access to primary mental healthcare.

Adolescent Total and Mental Health–Related Emergency Department Visits During the COVID-19 Pandemic

Previous research has assessed changes in pediatric and adolescent health care utilization during the COVID-19 pandemic; however, less is known regarding how the pandemic affected adolescents' use of emergency care, specifically for mental health (MH). To determine how adolescents (ages 12-17 years), compared with other age groups, sought help in emergency departments (EDs) in general and for MH conditions during the COVID-19 pandemic. In this cross-sectional study, National Syndromic Surveillance Program data and the Centers for Disease Control and Prevention Mental Health, version 1, query were used to track patterns in weekly adolescent ED visits by region across the 10 US Department of Health and Human Services regions from January 2019 through December 2021. Data analysis was performed in April and May 2023. Total ED visits, MH-related ED visits, and the proportion of total ED visits that were MH related by week-region. Both weekly regional ED visits and MH-related ED visits dropped after the onset of the pandemic. Because total ED visits dropped more than MH-related ED visits, the proportion of MH-related ED visits increased for the adolescent group. Total ED visits only returned to prepandemic weekly levels (2019: mean [range], 7358 [715-25 908] visits) in the middle of 2021 (overall in 2021: mean [range], 6210 [623-25 777] visits). Mental health-related visits also dropped in 2020 but rebounded to prepandemic weekly levels (2019: mean [range], 634 [56-1703] visits) by the end of 2020 (mean [range], 533 [39-1800] visits). This cross-sectional study suggests that families' perceptions of the need for emergent MH care were reduced during the pandemic by less than their perception of the need for emergency care overall. Emergency departments should be equipped to provide critical care specifically for adolescents facing MH emergencies.

Patterns of US Mental Health–Related Emergency Department Visits During the COVID-19 Pandemic

Numerous studies have shown that the prevalence of mental health (MH) conditions worsened during the COVID-19 pandemic. Further research is needed on this phenomenon over a longer time horizon that considers the increasing trend in MH conditions before the pandemic, after the pandemic onset, and after vaccine availability in 2021. To track how patients sought help in emergency departments (EDs) for non-MH and MH conditions during the pandemic. This cross-sectional study used administrative data on weekly ED visits and a subset of visits for MH from the National Syndromic Surveillance Program from January 1, 2019, to December 31, 2021. Data were reported from the 10 US Department of Health and Human Services (HHS) regions (Boston, New York, Philadelphia, Atlanta, Chicago, Dallas, Kansas City, Denver, San Francisco, and Seattle) for five 11-week periods. Data analysis was performed in April 2023. Weekly trends in total ED visits, mean MH-related ED visits, and proportion of ED visits for MH conditions were investigated to determine changes in each measure after the pandemic onset. Prepandemic baseline levels were established from 2019 data, and time trends of these patterns were examined in the corresponding weeks of 2020 and 2021. A fixed-effects estimation approach with weekly ED region data by year was used. There were 1570 total observations in this study (52 weeks in 2019, 53 weeks in 2020, and 52 weeks in 2021). Statistically significant changes in non-MH and MH-related ED visits were observed across the 10 HHS regions. The mean total number of ED visits decreased by 45 117 (95% CI, -67 499 to -22 735) visits per region per week (39% decrease; P = .003) in the weeks after the pandemic onset compared with corresponding weeks in 2019. The mean number of ED visits for MH conditions (-1938 [95% CI, -2889 to -987]; P = .003) decreased significantly less (23% decrease) than the mean number of total visits after the onset of the pandemic, increasing the mean (SD) proportion of MH-related ED visits from 8% (1%) in 2019 to 9% (2%) in 2020. In 2021, the mean (SD) proportion decreased to 7% (2%), and the mean number of total ED visits rebounded more than that of mean MH-related ED visits. In this study, MH-related ED visits demonstrated less elasticity than non-MH visits during the pandemic. These findings highlight the importance of addressing the provision of adequate MH services, both in acute and outpatient settings.

National Trends in Mental Health–Related Emergency Department Visits Among Youth, 2011-2020

There has been increasing concern about the burden of mental health problems among youth, especially since the COVID-19 pandemic. Trends in mental health-related emergency department (ED) visits are an important indicator of unmet outpatient mental health needs. To estimate annual trends in mental health-related ED visits among US children, adolescents, and young adults between 2011 and 2020. Data from 2011 to 2020 in the National Hospital Ambulatory Medical Care Survey, an annual cross-sectional national probability sample survey of EDs, was used to examine mental health-related visits for youths aged 6 to 24 years (unweighted = 49 515). Mental health-related ED visits included visits associated with psychiatric or substance use disorders and were identified by International Classification of Diseases-Ninth Revision, Clinical Modification (ICD-9-CM; 2011-2015) and ICD-10-CM (2016-2020) discharge diagnosis codes or by reason-for-visit (RFV) codes. We estimated the annual proportion of mental health-related pediatric ED visits from 2011 to 2020. Subgroup analyses were performed by demographics and broad psychiatric diagnoses. Multivariable-adjusted logistic regression analyses estimated factors independently associated with mental health-related ED visits controlling for period effects. From 2011 to 2020, the weighted number of pediatric mental health-related visits increased from 4.8 million (7.7% of all pediatric ED visits) to 7.5 million (13.1% of all ED visits) with an average annual percent change of 8.0% (95% CI, 6.1%-10.1%; P < .001). Significant linearly increasing trends were seen among children, adolescents, and young adults, with the greatest increase among adolescents and across sex and race and ethnicity. While all types of mental health-related visits significantly increased, suicide-related visits demonstrated the greatest increase from 0.9% to 4.2% of all pediatric ED visits (average annual percent change, 23.1% [95% CI, 19.0%-27.5%]; P < .001). Over the last 10 years, the proportion of pediatric ED visits for mental health reasons has approximately doubled, including a 5-fold increase in suicide-related visits. These findings underscore an urgent need to improve crisis and emergency mental health service capacity for young people, especially for children experiencing suicidal symptoms.

Emergency department visits for mental disorders and the built environment: Residential greenspace and historical redlining

The built environment has been increasingly shown to impact mental health. However, little is known about how and the extent to which exposure to greenspace in the residential environment is associated with emergency department visits for mental disorders. In addition, despite recent findings highlighting the links between historical discriminatory housing policies and health outcomes, no evidence is available regarding historical redlining and mental health. We aimed to investigate the extent to which the availability of greenspace in residential surroundings and historical redlining was associated with risks of mental disorder-related emergency department visits. In this ecological study, we analyzed state-wide data on emergency room visits for mental health in all metropolitan areas in Texas between 2016 and 2019. Greenspace coverage was determined using the National Land Cover Database. Historical redlining was defined as the type C (definitely declining) or D (hazardous) designations according to the 1930 s Home Owners’ Loan Corporation (HOLC) Security Maps. We fitted a conditional autoregressive spatial model with zero truncated negative binomial distribution to assess associations among emergency department visits, greenspace availability, and redlining, adjusted for risk and protective urban and social-demographic factors. We found that, with a 1% increase in greenspace coverage in a zip code area, the risk of emergency department visits due to mental health disorders was expected to decrease by 0.16% (IRR = 0.9984, 95% CI: 0.9971–0.9997). Meanwhile, a 1% increase of historically redlining zones was associated with a 0.88% increase (IRR = 1.0088, 95% CI: 1.0056-1.0120) in the risk of emergency department visits for mental health disorders. Our findings support the notion that exposure to natural environments is linked to lower risks of emergency department visits for mental disorders. They also indicate that systematic segregation institutionalized by historical housing policies might be related to present-day mental health-related emergency department visits. This study offers novel insights into the built environmental correlates of mental health and provides planning and policy implications related to mental health and health equity promotion.

Ambient heat and emergency department visits for mental health in Canada: assessing temporal variations by greenspace, urbanicity and socioeconomic status

BACKGROUND AND AIM Although previous research has suggested that greenspace might attenuate health risks associated with ambient heat, there is limited research on mental health disorders. Thus, we evaluated the effect modification of greenspace on heat-related mental health emergency department (ED) visits and whether these effects changed over time. METHODS We conducted a case-crossover study for mental health-related ED visits in Canada between 2004 and 2021 during warm-season months (May to August). ED visits for all Canadians living in 111 health regions were included. Daily average temperature as well as greenspace exposure, estimated by the Normalized Difference Vegetation Index (NDVI), were assigned to individuals at their residential location. Extreme heat was defined as the 95th percentile of the health region-specific warm-season temperature distribution. Conditional logistic regression was used to estimate associations between heat and mental health-related ED visits. RESULTS A total of 10,638,372 ED visits for any mental health condition were included. Days of extreme heat were associated with an increased risk of ED visits for any mental health condition (OR = 1.07; 95% CI: 1.05-1.09). In the earlier part of the study period (2004–2009), the associations between ambient heat and mental health ED visits were stronger among individuals exposed to the lowest quartile of NDVI exposure (OR = 1.20; 95% CI: 1.15-1.25), compared to individuals in the highest quartile of NDVI (OR = 1.01; 95% CI: 0.96-1.07). This difference, however, accentuated in the later part of the study (2016-2021) with the ORs for regions in the lowest quartile of NDVI increasing to 1.29 (95% CI: 1.25-1.34) and remaining stable for regions in the highest quartile. Effects appeared strongest in the most deprived socioeconomic areas. CONCLUSIONS Potential health benefits of greenspaces should be considered in mitigation strategies regarding the impacts of climate change on mental health ED visits.

Characterizing people with frequent emergency department visits and substance use: a retrospective cohort study of linked administrative data in Ontario, Alberta, and B.C., Canada

BackgroundSubstance use is common among people who visit emergency departments (EDs) frequently. We aimed to characterize subgroups within this cohort to better understand care needs/gaps, and generalizability of characteristics in three Canadian provinces.MethodsThis was a retrospective cohort study (April 1st, 2013 to March 31st, 2016) of ED patients in Ontario, Alberta, and British Columbia (B.C.) We included patients ≥ 18 years with substance use-related healthcare contact during the study period and frequent ED visits, defined as those in the top 10% of ED utilization when all patients were ordered by annual ED visit number. We used linked administrative databases including ED visits and hospitalizations (all provinces); mental heath-related hospitalizations (Ontario and Alberta); and prescriptions, physician services, and mortality (B.C.). We compared to cohorts of people with (1) frequent ED visits and no substance use, and (2) non-frequent ED visits and substance use.We employed cluster analysis to identify subgroups with distinct visit patterns and clinical characteristics during index year, April 1st, 2014 to March 31st, 2015.ResultsIn 2014/15, we identified 19,604, 7,706, and 9,404 people with frequent ED visits and substance use in Ontario, Alberta, and B.C (median 37–43 years; 60.9–63.0% male), whose ED visits and hospitalizations were higher than comparison groups.In all provinces, cluster analyses identified subgroups with “extreme” and “moderate” frequent visits (median 13–19 versus 4–6 visits/year). “Extreme” versus “moderate” subgroups had more hospitalizations, mental health-related ED visits, general practitioner visits but less continuity with one provider, more commonly left against medical advice, and had higher 365-day mortality in B.C. (9.3% versus 6.6%; versus 10.4% among people with frequent ED visits and no substance use, and 4.3% among people with non-frequent ED visits and substance use). The most common ED diagnosis was acute alcohol intoxication in all subgroups.ConclusionsSubgroups of people with “extreme” (13–19 visits/year) and “moderate” (4–6 visits/year) frequent ED visits and substance use had similar utilization patterns and characteristics in Ontario, Alberta, and B.C., and the “extreme” subgroup had high mortality. Our findings suggest a need for improved evidence-based substance use disorder management, and strengthened continuity with primary and mental healthcare.

Age and sex trends among mental health-related emergency department visits in North Carolina

Whether patients present to the emergency department (ED) with physical ailments and comorbid psychiatric needs or primary psychiatric complaints, understanding differences in clinically relevant age and sex patterns over time is crucial to optimal psychiatric care in the ED setting. We used population-level surveillance data provided by the North Carolina Disease Event Tracking and Epidemiologic Collection Tool (NC DETECT) from January 1, 2008, through December 31, 2014. Mental health-related (MHR) ED visits were identified by International Classification of Diseases, Clinical Modification 9th revision (ICD-9-CM) codes analyzed in the Agency for Healthcare Research and Quality (AHRQ) clinical classification software groupings of related diagnostic categories. Trends were assessed based on total and average annual visit counts. We identified approximately 4 million MHR ED visits. The average number of visits per year was highest among 50-year-olds, while patients over the age of 90 had the highest proportion of their ED visits associated with an MHR code. Mood disorders were more prevalent among females, while substance use disorders were more prevalent among males. Within MHR categories, age-related peaks did not differ by sex except for suicide and self-inflicted injury. Whether it be a teenage boy presenting with suicidal ideation, a middle-aged man presenting with alcohol abuse, or an elderly female presenting with dementia, ED MHR visits’ needs vary across the lifespan. Understanding these trends is important to holistic patient care.

Changes and Inequities in Adult Mental Health–Related Emergency Department Visits During the COVID-19 Pandemic in the US

The COVID-19 pandemic has negatively affected adult mental health (MH), with racial and ethnic minoritized groups disproportionately affected. To examine changes in adult MH-related emergency department (ED) visits into the Delta variant pandemic period and identify changes and inequities in these visits before and during COVID-19 case surges. This epidemiologic cross-sectional study used National Syndromic Surveillance Program data from US adults aged 18 to 64 years from 1970 to 2352 ED facilities from January 1, 2019, to August 14, 2021. All MH-related ED visits and visits related to 10 disorders (ie, anxiety, depressive, bipolar, schizophrenia spectrum, trauma- and stressor-related, attention-deficit/hyperactivity, disruptive behavioral and impulse, obsessive-compulsive, eating, and tic disorders) were identified. The following periods of MH-related ED visits were compared: (1) high Delta variant circulation (July 18-August 14, 2021) with a pre-Delta period (April 18-May 15, 2021), (2) after a COVID-19 case peak (February 14-March 13, 2021) with during a peak (December 27, 2020-January 23, 2021), and (3) the Delta period and the period after a COVID-19 case peak with the respective corresponding weeks during the prepandemic period. ED visits for 10 mental disorders and all MH-related visits. This cross-sectional study included 107 761 319 ED visits among adults aged 18 to 64 years (59 870 475 [56%] women) from January 1, 2019, to August 14, 2021. There was stability in most MH-related ED visit counts between the Delta and pre-Delta periods (percentage change, -1.4% to -7.5%), except for eating disorders (-11.9%) and tic disorders (-19.8%) and after a COVID-19 case peak compared with during a peak (0.6%-7.4%). Most MH-related ED visit counts declined in the Delta period relative to the prepandemic period (-6.4% to -30.7%); there were fluctuations by disorder when comparing after a COVID-19 case peak with the corresponding prepandemic period (-15.4% to 11.3%). Accounting for ED visit volume, MH-related ED visits were a smaller proportion of visits in the Delta period compared with the pre-Delta period (visit ratio, 0.86; 95% CI, 0.85-0.86) and prepandemic period (visit ratio, 0.80; 95% CI, 0.79-0.80). After a COVID-19 case peak, MH-related ED visits were a larger proportion of ED visits compared with during a peak (visit ratio, 1.04; 95% CI, 1.03-1.04) and the corresponding prepandemic period (visit ratio, 1.11; 95% CI, 1.11-1.12). Of the 2 510 744 ED visits included in the race and ethnicity analysis, 24 592 (1%) were American Indian or Alaska Native persons, 33 697 (1%) were Asian persons, 494 198 (20%) were Black persons, 389 740 (16%) were Hispanic persons, 5000 (0.2%) were Native Hawaiian or Other Pacific Islander persons, and 1 172 683 (47%) were White persons. There was between- and within-group variation in ED visits by race and ethnicity and increases in selected disorders after COVID-19 peaks for adults aged 18 to 24 years. Results of this cross-sectional study suggest that EDs may have increases in MH-related visits after COVID-19 surges, specifically for young adults and individual racial and ethnic minoritized subpopulations. Public health practitioners should consider subpopulation-specific messaging and programmatic strategies that address differences in MH needs, particularly for those historically marginalized.

Five-Year Trends in Pediatric Mental Health Emergency Department Visits in Massachusetts: A Population-Based Cohort Study

To evaluate temporal changes in pediatric emergency department (ED) visits for mental health problems in Massachusetts based on diagnoses and patient characteristics and to assess trends in all-cause pediatric ED visits. This statewide population-based retrospective cohort study used the Massachusetts All-Payer Claims Database, which includes almost all Massachusetts residents. The study sample consisted of residents aged <21years who were enrolled in a health plan between 2013 and 2017. Using multivariate regression, we examined temporal trends in mental health-related and all-cause ED visits in 2013-2017, with person-quarter as the unit of analysis; we also estimated differential trends by sociodemographic and diagnostic subgroups. The outcomes were number of mental health-related (any diagnosis, plus 14 individual diagnoses) and all-cause ED visits/1000 patients/quarter. Of the 967 590 Massachusetts residents in our study (representing 14.8 million person-quarters), the mean age was 8.1years, 48% were female, and 57% had Medicaid coverage. For this population, mental health-related (any) and all-cause ED visits decreased from 2013 to 2017 (P<.001). Persons aged 18-21years experienced the largest declines in mental health-related (63.0% decrease) and all-cause (60.9% decrease) ED visits. Although mental health-related ED visits declined across most diagnostic subgroups, ED visits related to autism spectrum disorder-related and suicide-related diagnoses increased by 108% and 44%, respectively. Overall rates of pediatric ED visits with mental health diagnoses in Massachusetts declined from 2013 to 2017, although ED visits with autism- and suicide-related diagnoses increased. Massachusetts' policies and care delivery models aimed at pediatric mental health may hold promise, although there are important opportunities for improvement.

Mental Health-Related Emergency Department Visits Among Children During The Early COVID-19 Pandemic.

ObjectiveTo measure univariate and covariate‐adjusted trends in children's mental health‐related emergency department (MH‐ED) use across geographically diverse areas of the U.S. during the first wave of the Coronavirus‐2019 (COVID‐19) pandemic.MethodThis is a retrospective, cross‐sectional cohort study using electronic health records from four academic health systems, comparing percent volume change and adjusted risk of child MH‐ED visits among children aged 3–17 years, matched on 36‐week (3/18/19–11/25/19 vs. 3/16/20–11/22/20) and 12‐week seasonal time intervals. Adjusted incidence rate ratios (IRR) were calculated using multivariate Poisson regression.ResultsVisits declined during spring‐fall 2020 (n = 3892 vs. n = 5228, −25.5%) and during spring (n = 1051 vs. n = 1839, −42.8%), summer (n = 1430 vs. n = 1469, −2.6%), and fall (n = 1411 vs. n = 1920, −26.5%), compared with 2019. There were greater declines among males (28.2% vs. females −22.9%), children 6–12‐year (−28.6% vs. −25.9% for 3–5 years and −22.9% for 13–17 years), and Black children (−34.8% vs. −17.7% to −24.9%). Visits also declined for developmental disorders (−17.0%) and childhood‐onset disorders (e.g., attention deficit and hyperactivity disorders; −18.0%). During summer‐fall 2020, suicide‐related visits rose (summer +29.8%, fall +20.4%), but were not significantly elevated from 2019 when controlling for demographic shifts. In contrast, MH‐ED use during spring‐fall 2020 was significantly reduced for intellectual disabilities (IRR 0.62 [95% CI 0.47–0.86]), developmental disorders (IRR 0.71 [0.54–0.92]), and childhood‐onset disorders (IRR 0.74 [0.56–0.97]).ConclusionsThe early pandemic brought overall declines in child MH‐ED use alongside co‐occurring demographic and diagnostic shifts. Children vulnerable to missed detection during instructional disruptions experienced disproportionate declines, suggesting need for future longitudinal research in this population.

Substance Use-related Emergency Department Visits and Resource Utilization.

IntroductionSubstance use-related visits to the emergency department (ED) have been linked to higher service delivery costs, although little is known about the specific services used. Our goal In this study was to describe the recent trends of substance use-related ED visits and assess the association between substance use and specific ED resource utilization.MethodsWe performed a retrospective, cross-sectional study using the National Hospital Ambulatory Medical Care Survey (NHAMCS) data from 2013–2018. All ED visits in the United States for patients ≥18 years of age were included. The primary exposure was having substance use included as a chief complaint or diagnosis, which we identified using the International Classification of Diseases, 9th and 10th revisions, codes. The primary outcome was the use of diagnostic services (including laboratory studies and cardiac monitoring) or imaging studies in the ED.ResultsThe study sample included 95,506 visits in the US, extrapolating to over 619 million ED visits nationwide. The total number of ED visits remained stable during the study period, but substance use-related visits increased by 45%, with these visits making up 2.93% of total ED visits in 2013 and 4.25% in 2018. This increase was primarily driven by stimulant-, sedative- (opioids and benzodiazepines), and hallucinogen-related visits. Mental health-related visits rose in parallel by 66% during the same period. Compared to non-substance use-related visits, substance use-related visits were more likely to undergo any diagnostic study (adjusted odds ratio [aOR] 1.28; 95% confidence interval (CI): 1.11–1.47; P = 0.001), toxicology screening (aOR 10.15; 95% CI: 8.84–11.66), but less likely to have imaging studies (aOR 0.62; 95% CI: 0.56–0.68; P <0.0001). In stratified analyses, substance use-related visits with concurrent mental health disorders were more likely to undergo imaging studies (aOR 1.56; 95% CI: 1.09–2.22), while findings were opposite for those without concurrent mental health disorders (aOR 0.64; 95% CI: 0.51–0.71; P for interaction <0.0001).ConclusionSubstance use- and mental health-related ED visits are rising, and they are associated with increased resource utilization. Further studies are needed to provide more guidance in the approach to acute services in this vulnerable population.

Association Between Ambient Heat and Risk of Emergency Department Visits for Mental Health Among US Adults, 2010 to 2019

The implications of extreme heat for physical health outcomes have been well documented. However, the association between elevated ambient temperature and specific mental health conditions remains poorly understood. To investigate the association between ambient heat and mental health-related emergency department (ED) visits in the contiguous US among adults overall and among potentially sensitive subgroups. This case-crossover study used medical claims data obtained from OptumLabs Data Warehouse (OLDW) to identify claims for ED visits with a primary or secondary discharge psychiatric diagnosis during warm-season months (May to September) from 2010 through 2019. Claims for adults aged 18 years or older with commercial or Medicare Advantage health insurance who were living in 2775 US counties were included in the analysis. Emergency department visits were excluded if the Clinical Classifications Software code indicated that the visits were for screening for mental health outcomes and impulse control disorders. County-specific daily maximum ambient temperature on a continuous scale was estimated using the Parameter-Elevation Relationships on Independent Slopes model. Extreme heat was defined as the 95th percentile of the county-specific warm-season temperature distribution. The daily incidence rate of cause-specific mental health diagnoses and a composite end point of any mental health diagnosis were assessed by identifying ED visit claims using primary and secondary discharge diagnosis International Classification of Diseases, Ninth Revision and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes. Conditional logistic regression models were used to estimate the incidence rate ratio (IRR) and 95% CIs for the association between daily temperature and incidence rates of ED visits. Data from 3 496 762 ED visits among 2 243 395 unique individuals were identified (56.8% [1 274 456] women; mean [SD] age, 51.0 [18.8] years); of these individuals, 14.3% were aged 18 to 26 years, 25.6% were aged 27 to 44 years, 33.3% were aged 45 to 64 years, and 26.8% were aged 65 years or older. Days of extreme heat were associated with an IRR of 1.08 (95% CI, 1.07-1.09) for ED visits for any mental health condition. Associations between extreme heat and ED visits were found for specific mental health conditions, including substance use disorders (IRR, 1.08; 95% CI, 1.07-1.10); anxiety, stress-related, and somatoform disorders (IRR, 1.07; 95% CI, 1.05-1.09); mood disorders (IRR, 1.07; 95% CI, 1.05-1.09); schizophrenia, schizotypal, and delusional disorders (IRR, 1.05; 95% CI, 1.03-1.07); self-harm (IRR, 1.06; 95% CI, 1.01-1.12); and childhood-onset behavioral disorders (IRR, 1.11; 95% CI, 1.05-1.18). In addition, associations were higher among men (IRR, 1.10; 95% CI, 1.08-1.12) and in the US Northeast (IRR, 1.10; 95% CI, 1.07-1.13), Midwest (IRR, 1.11; 95% CI, 1.09-1.13), and Northwest (IRR, 1.12; 95% CI, 1.03-1.21) regions. In this case-crossover study of a large population of US adults with health insurance, days of extreme heat were associated with higher rates of mental health-related ED visits. This finding may be informative for clinicians providing mental health services during periods of extreme heat to prepare for increases in health service needs when times of extreme heat are anticipated.

Racial disparities in emergency mental healthcare utilization among birthing people with preterm infants

BACKGROUND:Birthing people of color are more likely to deliver low birthweight and preterm infants, populations at significant risk of morbidity and mortality. Birthing people of color are also at higher risk for mental health conditions and emergency mental healthcare utilization postpartum. Although this group has been identified as high risk in these contexts, it is not known whether racial and ethnic disparities exist in mental healthcare utilization among birthing people who have delivered preterm.OBJECTIVE:We sought to determine if racial and ethnic disparities exist in postpartum mental healthcare-associated emergency department visits or hospitalizations for birthing people with preterm infants in a large and diverse population.STUDY DESIGN:This population-based historic cohort study used a sample of Californian live-born infants born between 2011 and 2017 with linked birth certificates and emergency department visit and hospital admission records from the California Statewide Health Planning and Development database. The sample was restricted to preterm infants (<37 weeks’ gestation). Self-reported race and ethnicity groups included Hispanic, non-Hispanic Black, non-Hispanic Asian, non-Hispanic White, and non-Hispanic others. Mental health diagnoses were identified from the International Classification of Diseases Ninth and Tenth revision codes recorded in emergency department and hospital discharge records. Logistic regression analysis was used to estimate the association between mental health-related emergency department visits and rehospitalizations by race or ethnicity compared with non-Hispanic White birthing people and controlling for the following characteristics and health condition covariates: age, parity, previous preterm birth, body mass index, smoking, alcohol use, hypertension, diabetes, previous mental health diagnosis, and prenatal care.RESULTS:Of 204,539 birthing people who delivered preterm infants in California, 1982 visited the emergency department and 836 were hospitalized in the first year after preterm birth for a mental health-related illness. Black birthing people were more likely to have a mental health-related emergency department visit and hospitalization (risk ratio, 1.8; 95% confidence interval, 1.5–2.0 and risk ratio, 1.9; 95% confidence interval, 1.5–2.3, respectively) within the first postpartum year than White birthing people. Hispanic and Asian birthing people were less likely to have mental health-related emergency department visits (adjusted risk ratio, 0.7; 95% confidence interval, 0.7–0.8 and adjusted risk ratio, 0.2; 95% confidence interval, 0.2–0.3, respectively) and hospitalizations (adjusted risk ratio, 0.6; 95% confidence interval, 0.5–0.7 and adjusted risk ratio, 0.2; 95% confidence interval, 0.1–0.3, respectively). When controlling for birthing people with a previous mental health diagnosis and those without, the disparities remained the same.CONCLUSION:Racial and ethnic disparities exist in emergency mental healthcare escalation among birthing people who have delivered preterm infants. Our findings highlight a need for further investigation into disparate mental health conditions, exacerbations, access to care, and targeted hospital and legislative policies to prevent emergency mental healthcare escalation and reduce disparities.

Effects of High-Deductible Health Plans on Enrollees With Mental Health Conditions With and Without Substance Use Disorders.

High-deductible health plans (HDHPs) are increasingly common in the U.S. health insurance market and are intended to reduce the use of low-value services, but evidence suggests that HDHP enrollees also reduce the use of high-value services. This study examined the effects of HDHPs on enrollees with mental health conditions, a population with high levels of unmet treatment need, often because of financial barriers. Enrollees with a co-occurring substance use disorder have greater treatment needs and unique barriers to care, perhaps changing their response to an HDHP. Commercial health insurance claims data in a difference-in-differences design was used to evaluate the effect of an employer's offer of an HDHP on 6,627,128 enrollee-years among enrollees with mental health conditions, stratified by having a co-occurring substance use disorder or not. Among enrollees without a co-occurring substance use disorder, an HDHP offer was associated with a 4.8% (95% confidence interval [CI]=2.4%-7.2%) reduction in overall spending on mental health care, despite an 11.3% (95% CI=1.0%-21.6%) increase in spending on mental health-related emergency department visits. Among enrollees with a co-occurring substance use disorder, no significant changes attributable to an HDHP offer were found in most categories of spending on combined mental health and substance use disorder care, apart from a 4.5% (95% CI=1.9%-7.2%) reduction in spending on psychotropic medications. HDHPs may reduce use of necessary care among enrollees with mental health conditions, which could exacerbate undertreatment in this population and result in adverse health outcomes.

Mental Health–Related Emergency Department Visits in Adolescents Before and During the COVID-19 Pandemic: A Multicentric Retrospective Study

PurposeThe purpose of this study was to compare pre/post-COVID-19 changes in mental health–related emergency department visits among adolescents. MethodsWe conducted a retrospective analysis of all mental health–related emergency department visits in two large tertiary pediatric hospital centers between January 2018 and December 2020. We described monthly pre/post-COVID-19 changes in frequency and proportion of mental health visits as well as changes in hospitalization rates for eating disorders, suicidality, substance use, and other mental health conditions. ResultsWe found an increase in the proportion of mental health–related emergency department visits during the months of July–December 2020 (p < .01). There was a 62% increase in eating disorder visits between 2018–2019 and 2020 (p < .01). No pre pandemic/postpandemic changes were found in the proportion of visits resulting in hospitalization for any of the four diagnostic categories. ConclusionsOur study suggests significant impacts of COVID-19 on adolescent mental health and a need for further longitudinal research work in this area.

36 Comparison of Mental Health Visits at a Military Treatment Facility Emergency Department Pre- And Post-COVID-19 Pandemic

There is a paucity of quantitative research regarding the effect of COVID-19 on emergency department (ED) visits in the United States, and specifically mental health-related ED visits. The small existing body of research describes an overall decline in ED visits worldwide; however, there are anecdotal reports that psychiatric complaints to the ED have increased during the pandemic. The primary objective of this study was to describe the volume of mental health ED visits at a single ED during the COVID-19 pandemic compared to previous years. This was a single-center, retrospective chart review of adult patients evaluated in the ED at an academic military medical facility from March-December of 2017-2020 for mental health. The electronic medical record was queried for 1,542 mental health ICD-10 diagnosis codes. Demographic data including age, sex, disposition, diagnosis, and beneficiary status were collected. Tests of association included Pearson Chi-square with Bonferroni correction for post-hoc tests and one-way ANOVA. There were a total of 1,486 mental health ED visits from March-December 2020, compared to an average of 1,668 visits from March-December 2017-2019. Statistically significant (p<0.05) differences, between 2020 and the prior three years combined, were identified in the categories of age, disposition, beneficiary status, and diagnosis. In 2020, there was a lower proportion of visits for patients aged ≥ 60 (1.2%) than in 2017-2019 (2.5%). Active duty patients comprised a lower proportion in 2020 (17.6%) versus 2017-2019 (23.0%). Proportionately fewer patients were admitted in 2020 (25.2%) versus 2017-2019 (29.2%). Adjustment disorders made up 19.0% of visits in 2020 versus 23.2% in 2017-2019 and suicidal ideation and intentional self-inflicted injury comprised 43.3% in 2020 compared with 40.4% in 2017-2019. There was a significant decline in ED visits for patients over the age of 60 and for active duty military patients. Overall, fewer patients were admitted compared to previous years. There was a significant increase in patients diagnosed with suicidal ideation and intentional self-inflicted injury in 2020 compared to previous years. The COVID-19 pandemic and associated quarantines have negatively affected mental health worldwide. Active duty military and elderly patients were uniquely impacted. Both groups have been subject to highly restrictive limitations during the pandemic. Alarmingly, this study shows increased rates of self-harm and suicidal ideation, yet a lower likelihood of these populations to present to the ED for mental health care. Further study is needed to determine why these effects were seen, and if there is a higher risk for suicide attempt or completion in these populations.
