Substance Use, Homelessness, Mental Illness and Medicaid Coverage: A Set-up for High Emergency Department Utilization

Barriers and Facilitators to High Emergency Department Use Among Patients with Mental Disorders: A Qualitative Investigation

This qualitative study explored reasons for high emergency department (ED) use (3 + visits/year) among 299 patients with mental disorders (MD) recruited in four ED in Quebec, Canada. A conceptual framework including healthcare system and ED organizational features, patient profiles, and professional practice guided the content analysis. Results highlighted insufficient access to and inadequacy of outpatient care. While some patients were quite satisfied with ED care, most criticized the lack of referrals or follow-up care. Patient profiles justifying high ED use were strongly associated with health and social issues perceived as needing immediate care. The main barriers in professional practice involved lack of MD expertise among primary care clinicians, and insufficient follow-up by psychiatrists in response to patient needs. Collaboration with outpatient care may be prioritized to reduce high ED use and improve ED interventions by strengthening the discharge process, and increasing access to outpatient care.

Changes in Emergency Department Utilization in Vulnerable Populations After COVID-19 Shelter-in-Place Orders

OBJECTIVES

This study aims to compare emergency department (ED) utilization and admission rates for patients with a history of mental health (MH) disorders, substance use disorders (SUDs), and social determinants of health (SDOH) before and after implementing COVID-19 shelter-in-place (SIP) orders.

METHODS

This was a retrospective, multicenter study leveraging electronic medical record (EMR) data from 20 EDs across a large Midwest integrated healthcare system from 5/2/2019 to 12/31/2019 (pre-SIP) and from 5/2/2020 to 12/31/2020 (post-SIP). Diagnoses were documented in the patient's medical records. Poisson and logistic regression models were used to evaluate ED utilization and admission rate changes.

RESULTS

A total of 871,020 ED encounters from 487,028 unique patients were captured. Overall, 2,572 (0.53%) patients had a documented Z code for SDOH. Patients with previously diagnosed MH disorders or SUDs were more likely to seek ED care after the SIP orders were implemented (risk ratio (RR): 1.20, 95% confidence interval (CI): 1.18-1.22, p<0.001), as were patients with SDOH (RR: 2.37, 95% CI: 2.19-2.55, p<0.001). Patients with both previously diagnosed MH disorders or SUDs and a documented SDOH had even higher ED utilization (RR: 3.31, 95% CI: 2.83-3.88, p<0.001) than those with either condition alone. Patients with MH disorders and SUDs (OR: 0.89, 95% CI: 0.86-0.92, p<0.001) or SDOH (OR: 0.67, 95% CI: 0.54-0.83, p<0.001) were less likely to be admitted post-SIP orders, while patients with a history of diseases of physiologic systems were more likely to be admitted.

CONCLUSION

Vulnerable populations with a history of MH disorders, SUDs, and SDOH experienced increased ED utilization but a lower rate of hospital admissions after the implementation of SIP orders. The findings highlight the importance of addressing these needs to mitigate the impact of public health crises on these populations.

Examining the Role of Self-Harm in the Relationship between Emergency Department Service Utilization and Trauma-Induced Homelessness among Homeless Individuals in Texas

Homelessness is a complex public health problem in the United States. Current or ongoing history of trauma among individuals adds to the complexity and challenges of homelessness. Our study assessed the moderating role of self-harm in the association between emergency department (ED) service utilization and trauma-induced homelessness (TIH) among adults in Texas. Homeless adults (N = 282) who completed their baseline Vulnerability Index Service Prioritization Decision Assistance Prescreen Tool survey between February 2021 and February 2022 at a Local Mental Health Authority in Texas were selected. The outcome variable, TIH, was assessed by current period of homelessness due to experiencing trauma or abuse. The main independent variable was ED utilization, while self-harm in the past year was assessed as the moderating variable. A multivariate logistic regression with a moderation analysis was conducted while adjusting for the covariates. Individuals who utilized ED services and engaged in self-harm and risky behaviors had greater odds of experiencing current period of TIH. Male respondents were less likely to experience TIH. Finally, engaging in self-harm significantly moderated the association between ED service use and TIH. This study may help inform efforts to develop tailored interventions and promote resilience-based approaches to improve health outcomes among individuals experiencing homelessness due to TIH.

Multicomponent Co-Occurring Disorders Treatment and Wraparound Services for Individuals Experiencing Chronic Homelessness

Individuals experiencing chronic homelessness have high rates of persistent co-occurring mental health and substance use disorders (COD), and they often have difficulty with service engagement and retention, resulting in symptom exacerbation and housing loss. This study pilot tested Maintaining Independence and Sobriety Through Systems Integration, Outreach and Networking (MISSION), a multicomponent wraparound treatment approach to improve COD symptoms and housing stability among individuals experiencing chronic homelessness and persistent COD. This open pilot study enrolled and assessed 109 individuals with a COD experiencing chronic homelessness and offered one year of MISSION. Statistically significant improvements were observed in behavioral health symptoms and functioning, days of illicit drug use, and housing stability. By treatment completion, 85% of participants were referred to social and behavioral supports. This pilot study demonstrates that MISSION helped to successfully engage participants in treatment, reduce substance use and mental health symptoms, and improve housing outcomes.

Imaging Utilization and Cost of Substance Use in an Urban Academic Medical Center During the Contemporary Opioid Epidemic

RATIONALE AND OBJECTIVES

To determine the recent impact of illicit substance use on imaging utilization and associated costs.

METHODS

Retrospective study from an inner city urban multi-site academic medical center. Institutional Review Board (IRB) approval was obtained with a waiver of informed consent. A substance use cohort comprised patients 12 years old presenting to the Emergency Department (ED) January 2017 to June 2019 with a positive urine toxicology and an ICD code associated with substance use. The comparison cohort was randomly selected from a group of ED patients who presented with no or negative urine toxicology and no documented substance use ICD code. Data extracted from the EMR included demographics, number and type of imaging studies, Charlson comorbidity index, and in-hospital mortality during the study period.

RESULTS

The substance use and comparison cohorts comprised 3191 and 3200 patients, respectively. The substance use cohort was older on average (mean age 45.67 ± 14.88 vs 43.91 ± 20.57 years), more often male (63% [2026/3191] vs. 39% [1255/3200]) and had a mean Charlson score 88% higher than the comparison cohort (3.33 vs 1.78). The majority of both cohorts were ethnic minorities (<10% white). The substance use cohort had significantly more imaging vs the comparison cohort, total 36,413 (mean 11.41 exams/patient) vs total 12,399 (mean 3.87 exams/patient), p < 0.0001, and was higher for all modalities except mammography. Average imaging costs per patient were nearly 300% higher for the substance use vs comparison cohort, ($1287.18 vs. $434.70).

CONCLUSION

Imaging utilization and associated costs were substantially higher for patients with a positive urine toxicology and substance use related ICD codes compared to the broader ED population in an underserved urban population.

Clinical and longitudinal patterns of frequent presenters to emergency departments: A multi-centre data linkage analysis

OBJECTIVE

To describe clinical characteristics and longitudinal patterns of representation in a cohort of patients who frequently present to EDs for care.

METHODS

A retrospective data analysis linking routinely collected ED data across three hospitals. The study population consisted of patients who presented to any ED on 10 or more occasions in any continuous 365-day period from 1 July 2015 to 30 June 2021. Presenting complaints were divided into those with any mental health, drug and alcohol, or social presentations (MHDAS group) and those without (non-MHDAS group). Outcomes of interest were number of presentations as well as temporal and facility clustering of presentations. A per patient regression analysis was performed to identify independent risk factors for increased presentations.

RESULTS

Presentations by 1640 frequent ED presenters in the study constituted 4.6% of total ED presentations. MHDAS study group were younger, predominantly English speaking, twice as likely to be married, had lower hospital admission rates and almost three times as many of them did not wait for treatment. Statistically significant differences were also found between these groups regarding presentation clustering, facility entropy, each of the four categories of the number of ED presentations, and Index of Relative Socio-Economic Advantage and Disadvantage.

CONCLUSION

Representations associated with MHDAS have a different trajectory of representation episodes compared to non-MHDAS group. Escalating number of presentations and clustering are important predictors of future representation numbers. Those 'did not waits' who appear to be representing would be the highest risk of ongoing and persistent representations in the future and should be the target of early interventions to ensure they are accessing appropriate care before this happens.

Substance Use Disorders, Mental Illness, and Health Care Utilization Among Adults With Recent Criminal Legal Involvement

OBJECTIVE

Individuals involved with the criminal legal system have higher rates of mental illness, addiction, and health care utilization. The authors examined whether substance use disorders and mental illness alone or in combination drive health care utilization among those with recent criminal legal involvement.

METHODS

This cross-sectional analysis used nationally representative data from U.S. adults with past-year criminal legal involvement (N=9,039) recorded in the National Survey on Drug Use and Health (2015-2019). Using adjusted negative binomial regression models, the authors estimated relative risks for health care utilization. Primary independent variable categories included neither substance use disorder nor mental illness, substance use disorder only, mental illness only, and both conditions. Health care utilization included emergency department (ED) visits and nights spent in inpatient care.

RESULTS

Relative to neither mental illness nor substance use disorder, mental illness alone was associated with significantly increased acute health care services use: for ED visits, incidence risk ratio (IRR)=1.43 (95% CI=1.18-1.75) and for inpatient stays, IRR=2.14 (95% CI=1.47-3.11). Having both conditions was associated with increased ED visits (IRR=1.62, 95% CI=1.38-1.91) and inpatient stays (IRR=4.16, 95% CI=2.98-5.82). Substance use disorder alone was associated only with higher risk for ED visits compared with neither condition (IRR=1.23, 95% CI=1.01-1.50).

CONCLUSIONS

Mental illness with or without co-occurring substance use disorder is a strong driver of acute health care utilization after interaction with the criminal legal system. Interventions tailored to the unique needs of individuals with mental illness or substance use disorder are needed for those with recent criminal legal involvement.

Patient Flow and Reutilization of Crisis Services Within 30 Days in a Comprehensive Crisis System

OBJECTIVE

Crisis services are undergoing an unprecedented expansion in the United States, but research is lacking on crisis system design. This study describes how individuals flow through a well-established crisis system and examines factors associated with reutilization of such services.

METHODS

This cross-sectional study used Medicaid claims to construct episodes describing the flow of individuals through mobile crisis, specialized crisis facility, emergency department, and inpatient services. Claims data were merged with electronic health record (EHR) data for the subset of individuals receiving care at a crisis response center. A generalized estimating equation was used to calculate adjusted odds ratios for demographic, clinical, and operational factors associated with reutilization of services within 30 days of an episode's end point.

RESULTS

Of 41,026 episodes, most (57.4%) began with mobile crisis services or a specialized crisis facility rather than the emergency department. Of the subset (N=9,202 episodes) with merged EHR data, most episodes (63.3%) were not followed by reutilization. Factors associated with increased odds of 30-day reutilization included Black race, homelessness, stimulant use, psychosis, and episodes beginning with mobile crisis services or ending with inpatient care. Decreased odds were associated with depression, trauma, and involuntary legal status. Most (59.3%) episodes beginning with an involuntary legal status ended with a voluntary status.

CONCLUSIONS

Crisis systems can serve a large proportion of individuals experiencing psychiatric emergencies and divert them from more restrictive and costly levels of care. Understanding demographic, clinical, and operational factors associated with 30-day reutilization may aid in the design and implementation of crisis systems.

Voices of the unhoused from Santa Fe, New Mexico: A mixed methods study of health status, substance use, and community harm reduction program perspectives

No published studies have examined the community service priorities and harm reduction perspectives of unhoused people in Santa Fe, New Mexico. We conducted a mixed methods pilot study of 56 unhoused people at community locations in Santa Fe to: (1) assess the current prevalence of chronic medical conditions and substance use; (2) highlight community service priorities; and (3) explore views of innovative community harm reduction programs. Our first hypothesis was there would be high prevalence of chronic medical conditions, for which we found high prevalence of post-traumatic stress disorder, major depression, substance use disorders, chronic pain, and hypertension. Our second hypothesis was that we would find top community service priorities of housing, food, and health care. We found long- and short-term housing and food, but not healthcare, top priorities. Our third hypothesis was that we would find mixed support for community harm reduction initiatives like managed alcohol programs and overdose prevention centers. We found positive, not mixed, support for these community harm reduction programs among Santa Fe's unhoused. Unhoused study participants ranged in age 27-77 years, with lifetime years unhoused from less than one year to 63 years. Study limitations included small sample size, convenience sampling, and descriptive results. Policies and program initiatives supporting additional Housing First options, managed alcohol programs, and overdose prevention centers in the Santa Fe community are clearly indicated to increase engagement with this vulnerable population. Future research should focus on inclusion of the perspectives of the unhoused in the design, conduct, evaluation, and dissemination of community programs to meet the needs of the unhoused, with re-defined outcomes to include changes in quality of life, program engagement, demarginalization, and future goals and plans, beyond currently utilized health and social service program outcome measures.

Profiles of patients with substance-related disorders who dropped out or not from addiction treatment

This longitudinal study identified profiles of patients with substance-related disorders (SRD) who did or did not drop out of specialized addiction treatment, integrating various patterns of outpatient service use. Medical administrative databases of Quebec (Canada) were used to investigate a cohort of 16,179 patients with SRD who received specialized addiction treatment. Latent class analysis identified patient profiles, based on multi-year outpatient service use. Four patient profiles related to treatment dropout were identified: patients who did not drop out and were low service users (Profile 1); patients who did not drop out and were high service users (Profile 2); patients who dropped out and were low service users (Profile 3); patients who dropped out and were high service users (Profile 4). Profile 1 had the best health and social conditions, while Profile 4 had the worst. The risks of being frequent emergency department users, being hospitalized or dying were highest in Profile 4, followed by Profiles 3, 2 and 1. Assertive treatment programs may be suited to Profile 4 and intensive case management programs to Profile 3. Collaborative care with higher psychosocial interventions and regularity of care may be extended to Profile 2 and interventions integrating motivational treatment to Profile 1.

Characterizing suicidal ideation, suicidal behaviors, and service utilization among unhoused individuals using a health information exchange

INTRODUCTION

Unhoused individuals have high rates of suicidal ideation (SI) and suicidal behaviors (SB), but few have studied the relative timing of homelessness and SI/SB. Our study examines the potential to use state-wide electronic health record data from Rhode Island's health information exchange (HIE) to identify temporal relationships, service utilization, and associations of SI/SB among unhoused individuals.

METHODS

We use timestamped HIE data for 5368 unhoused patients to analyze service utilization and the relative timing of homelessness versus SI/SB onset. Multivariable models identified associations of SI/SB, hospitalization, and repeat acute care utilization within 30 days from clinical features representing 10,000+ diagnoses captured within the HIE.

RESULTS

The onset of SI typically precedes homelessness onset, while the onset of SB typically follows. Weekly rates of suicide-related service utilization increased over 25 times the baseline rate during the week before and after homelessness onset. Over 50% of encounters involving SI/SB result in hospitalization. Of those engaging in acute care for suicide-related reasons, we found high rates of repeat acute care encounters.

CONCLUSION

HIEs are a particularly valuable resource for understudied populations. Our study demonstrates how longitudinal, multi-institutional data from an HIE can be used to characterize temporal associations, service utilization, and clinical associations of SI and behaviors among a vulnerable population at scale. Increasing access to services that address co-occurring SI/SB, mental health, and substance use is needed.

Profiles of quality of life among patients using emergency departments for mental health reasons

BACKGROUND

This study identified profiles associated with quality of life (QoL) and sociodemographic and clinical characteristics of patients using emergency departments (ED) for mental health reasons and associated these profiles with patient service use.

METHODS

Recruited in four Quebec (Canada) ED networks, 299 patients with mental disorders (MD) were surveyed from March 1st, 2021, to May 13th, 2022. Data from medical records were collected and merged with survey data. Cluster analysis was conducted to identify QoL profiles, and comparison analyses used to assess differences between them.

RESULTS

Four QoL profiles were identified: (1) Unemployed or retired men with low QoL, education and household income, mostly having substance-related disorders and bad perceived mental/physical health conditions; (2) Men who are employed or students, have good QoL, high education and household income, the least personality disorders, and fair perceived mental/physical health conditions; (3) Women with low QoL, multiple mental health problems, and very bad perceived mental/physical health conditions; (4) Mostly women with very good QoL, serious MD, and very good perceived mental/physical health conditions.

CONCLUSION

The profiles with the highest QoL (4 and 2) had better overall social characteristics and perceived their health conditions as superior. Profile 4 reported the highest level of satisfaction with services used. To improve QoL programs like permanent supportive housing, individual placement and support might be better implemented, and satisfaction with care more routinely assessed in response to patient needs - especially for Profiles 1 and 3, that show complex health and social conditions.

A 13-item Health of the Nation Outcome Scale (HoNOS-13): validation by item response theory (IRT) in patients with substance use disorder

BACKGROUND

The Health of the Nation Outcome Scale (HoNOS) is a widely used 12-item tool to assess mental health and social functioning. The French version has an added 13th item measuring adherence to psychotropic medication. The aim of the current study is to uncover the unknown pattern of the new item 13 and to compare the unidimensional and multidimensional fit of the new HoNOS-13 using Item Response Theory (IRT). This research question was studied among inpatients with substance use disorder (SUD).

METHODS

Six hundred and nine valid questionnaires of HoNOS-13 were analyzed using unidimensional (one-factor) and multidimensional (two-factor) IRT modeling.

RESULTS

The multidimensional model suggesting a first factor capturing psychiatric/impairment-related issues and a second factor reflecting social-related issues yielded better goodness-of-fit values compared to the unidimensional solution. This resulted in an improvement of all slope parameters which in turn translates to better discriminative power. Significant improvement in item location parameters were observed as well. The new item 13 had a good discriminative power (1.17) and covered a wide range of the latent trait (- 0.14 to 2.64).

CONCLUSIONS

We were able to validate the 13-item questionnaire including medication compliance and suggest that the HoNOS-13 can be recommended as a clinical evaluation tool to assess the problems and treatment needs for inpatients with SUD. Interestingly, the majority of item response categories are endorsed by respondents who are below and above the average levels of HoNOS. This indicates that the scale is able to discriminate between participants both at the low and at the high ends of the latent trait continuum. More importantly, the new item 13 has a good discriminative power and covers a broad range of the latent trait below and above the mean. It therefore has the desired profile of a good item and is a useful measure for the assessment of mental health and social functioning. Trial registration ClinicalTrials.gov, Identifier: NCT03551301.

What Brings You in Today? Sex, Race, Substance Type, and Other Sociodemographic and Health-Related Characteristics Predict if Substance Use is the Main Reason for a Clinical Encounter

Background: Substance-related diagnoses (SRDs) are a common healthcare presentation. This study identified sociodemographic and health-related characteristics associated with having an SRD as the primary reason for a clinical encounter compared to those with an SRD who are treated for other reasons. Methods: Electronic health record (EHR) data on patients with an SRD (n=12,358, ages 18-90) were used to assess if an SRD was the primary reason for a clinical encounter from January 1, 2012-January 1, 2018. Patients were matched on key demographic characteristics at a 1:1 ratio. Adjusting for covariates, odds ratios, and 95% confidence intervals were calculated. Results: In the matched cohort of 8,630, most reported male sex (65.8%), White race (70.0%), and single marital status (62.7%) with a mean age of 47.2 (SD=14.6). Patient reported female sex, Black race, age 70+, married status, and low-income (<$50,000) were associated with a lower likelihood of presenting to care for an SRD as the primary reason for a clinical encounter. A nicotine-, alcohol-, opioid-, or stimulant-related diagnosis was associated with a higher likelihood of presenting to care for an SRD as the primary reason for the clinical visit. Conclusion: This is the first study to investigate whether sociodemographic and health-related characteristics were associated with having an SRD as the primary reason for a clinical encounter. Using rigorous methods, we investigated a unique clinical question adding new knowledge to predictors of patients seeking clinical care. Understanding these predictors can help us better align service provision with population needs and inform new approaches to tailoring care.

Prevalence and correlates of experiencing drug-related discrimination among people who use drugs presenting at emergency department at high risk of opioid overdose

Objectives

Our objective is to determine if specific sociodemographic characteristics were associated with perceived drug-related discrimination among people who use drugs (PWUD) presenting for care in the emergency department (ED).

Methods

We conducted a secondary analysis of data from the Navigator trial, a randomized control trial of two behavioral interventions in the ED for people at risk of an opioid overdose. Participants included adult patients presenting to two Rhode Island EDs. Eligible participants included those high risk for an opioid overdose, resided or received most of their healthcare in Rhode Island, and were able to provide consent. The primary outcome of this analysis was self-reported feelings of drug-related discrimination by the medical community. The independent variables of interest included race/ethnicity, gender identity, and sexual orientation. Log-binomial multivariable regression models were constructed with all three independent variables of interest and a selection of sociodemographic covariates.

Results

Of 620 eligible participants, 251 (40.5%) reported ever experiencing drug-related discrimination in their lifetime. In the adjusted model, participants who identified as women and participants who identified as LGBQIA+ were more likely to report experiencing drug-related discrimination from the medical community in EDs. Racial/ethnic minority groups were less likely than White (non-Hispanic) participants to report drug-related discrimination.

Discussion

In this study population, White participants reported more drug-related discrimination than their minority counterparts, although female and LGBQIA+ patients reported more discrimination. Future studies should further assess the significance of these intersecting identities on self-reported discrimination. This knowledge could improve ED-based interventions, policies, and services for PWUD.

The status of patient portal use among Emergency Department patients experiencing houselessness: A large-scale single-center observational study

OBJECTIVE

Patient portal (PP) use has rapidly increased in recent years. However, the PP use status among houseless patients is largely unknown. We aim to determine 1) the PP use status among Emergency Department (ED) patients experiencing houselessness, and 2) whether PP use is linked to the increase in patient clinic visits.

METHODS

This is a single-center retrospective observational study. From March 1, 2019, to February 28, 2021, houseless patients who presented at ED were included. Their PP use status, including passive PP use (log-on only PP) and effective PP use (use PP of functions) was compared between houseless and non-houseless patients. The number of clinic visits was also compared between these two groups. Lastly, a multivariate logistic regression was analyzed to determine the association between houseless status and PP use.

RESULTS

We included a total of 236,684 patients, 13% of whom (30,956) were houseless at time of their encounter. Fewer houseless patients had effective PP use in comparison to non-houseless patients (7.3% versus 11.6%, p < 0.001). In addition, a higher number of clinic visits were found among houseless patients who had effective PP use than those without (18 versus 3, p < 0.001). The adjusted odds ratio of houseless status associated with PP use was 0.48 (95% CI 0.46-0.49, p < 0.001).

CONCLUSIONS

Houselessness is a potential risk factor preventing patient portal use. In addition, using patient portals could potentially increase clinic visits among the houseless patient population.

Long-Term Trends in Psychiatric Emergency Services Delivered by the Boston Emergency Services Team

Rising psychiatric emergency department (ED) presentations pose significant financial and administrative burdens to hospitals. Alternative psychiatric emergency services programs have the potential to alleviate this strain by diverting non-emergent mental health issues from EDs. This study explores one such program, the Boston Emergency Services Team (BEST), a multi-channel psychiatric emergency services provider intended for the publicly insured and uninsured population. BEST provides evaluation and treatment for psychiatric crises through specialized psychiatric EDs, a 24/7 hotline, psychiatric urgent care centers, and mobile crisis units. This retrospective review examines the sociodemographic and clinical characteristics of 225,198 BEST encounters (2005-2016). Of note, the proportion of encounters taking place in ED settings decreased significantly from 70 to 58% across the study period. Findings suggest that multi-focal, psychiatric emergency programs like BEST have the potential to reduce the burden of emergency mental health presentations and improve patient diversion to appropriate psychiatric care.

Emergency department outcomes for patients experiencing homelessness in England: retrospective cross-sectional study

BACKGROUND

Emergency departments (EDs) are an important point of access to health care for people experiencing homelessness. Evidence suggests that ED attendances by homeless people are more likely to result in leaving the ED without treatment, or dying in the ED. We investigate which diagnoses and patterns of health care use are associated with these (and other) discharge destinations and re-attendance within 7 days among homeless patients.

METHODS

We used national hospital data to analyze attendances of all 109 254 people experiencing homelessness who presented at any Type 1 ED in England over 2013-18. We used logistic regression to estimate the association of each outcome with primary diagnosis and patterns of healthcare use.

RESULTS

Compared with patients with no past ED use, patients with a high frequency of past ED use were more likely to leave without treatment and re-attend within 7 days. Patients not registered at a general practice were likelier to leave without treatment or die in the ED and had lower odds of unplanned re-attendance. A primary diagnosis of 'social problems' was associated with being discharged without follow-up. Patients with a psychiatric primary diagnosis were disproportionately likely to be referred to another health care professional/provider or an outpatient clinic.

CONCLUSIONS

Further research is needed to understand why some homeless patients leave the ED without treatment and whether their healthcare needs are being met. Some patients may be attending the ED frequently due to poor access to other services, such as primary care and social welfare.

Emergency department visit patterns in the recently discharged, violently injured patient: Retrospective cohort review

BACKGROUND

Analysis of the costs associated with emergency department (ED) visits after discharge for violent injury could highlight subgroups for the development of cost-effective interventions to support healing and prevent treatment failures in violently injured patients.

METHODS

A retrospective cohort review was conducted of all patients with return ED visits within 90 days of discharge after treatment for a violent injury occurring between July 1, 2016, and June 30, 2018. Hospital costs were calculated for each incidence and analyzed against demographic and injury type variables to identify trends.

RESULTS

218 return ED visits were identified. Hospital costs showed a high frequency of low-cost visits. For more complex visits, distinct cost patterns were observed for Black and LatinX males compared to White males as a function of age.

CONCLUSIONS

Analysis of hospital cost per visit identified trends among different subgroups. Underlying etiologies presumably vary between groups, but hypothesis-driven further investigation and needs assessment is required. Understanding the driving forces behind these cost trends may aid in developing effective interventions.

Rates and correlates of dual diagnosis among adults with psychiatric and substance use disorders in a nationally representative U.S sample

Treatment needs of adults diagnosed with both psychiatric and substance use disorders (i.e., dual diagnosis) have not received detailed characterization in a nationally representative US sample. Data from the National Epidemiologic Survey on Alcohol and Related Conditions Wave III were used to compare socio-behavioral, diagnostic, and service use characteristics of dually diagnosed adults to those with psychiatric disorders or SUDs alone. Adults with dual diagnosis were estimated to constitute 25.8% of those with any psychiatric disorder; 36.5% of those with any SUD and 17.8% of the 75.8 million adults with either disorder. Among those with psychiatric disorders, the independent correlates of dual diagnosis reflected substantial social or psychopathological disadvantages (e.g., violent behavior, poor mental health-related quality of life [HRQOL], police trouble, homelessness, and incarceration). Similarly, among those with SUD all independent correlates of dual diagnosis also reflected social or psychopathological disadvantages including poor mental HRQOL, witnessing trauma in childhood, childhood sex abuse, drug use diagnoses, suicide attempt, medical problems, having more than one SUD diagnosis, child neglect, repeated adult traumas, and less social support. Provision of medical, psychiatric, addiction and especially diverse social services in an integrated and accessible setting appear necessary and deserve further study.

Evaluation of the use of individualized patient care plans in frequent emergency department visitors with pain complaints

Background

Pain is one of the most common complaints that patients present to the emergency department for; emergency medicine providers are tasked with providing appropriate pain relief while simultaneously limiting the risk of personal and societal harm that may result from opioid misuse. The Lakeland Regional Medical Center developed a medical management program that identified frequent emergency department visitors with a chief complaint of pain. Individualized care plans were developed for these patients. A retrospective review was then conducted to assess the efficacy of these care plans in reducing the number of emergency department visits for pain-related complaints by the patients entered into the medical management program.

Results

There were 294 patients; 65% were male, and the median age was 41 (interquartile range: 33 to 51). A total of 80% percent of the patients were white, and the payors were as follows: 53% were self-pay, 42% were government programs, and 5% had private insurance. The three most common chronic pain complaints were 39% abdominal pain, 24% back/neck pain, and 23% headache/migraine (patients could have more than one area of pain). A total of 60% of the patients had a primary care provider, and another 18% had a pain management provider in addition to primary care.

Post plan admissions were significantly reduced to a median of 1 (IQR 0 to 3) with the Wilcoxon signed-rank test’s p-value of less than 0.001.

Conclusion

The authors describe their experience with a quality improvement initiative that identifies frequent emergency department visitors with a chief complaint of pain and provides individualized care plans to these patients. The goals of the program are to improve patient’s quality and consistency of care, through interventions that eliminate the prescribing of opioids while providing non-opioid alternatives.

Homelessness and the use of Emergency Department as a source of healthcare: a systematic review

BACKGROUND

Persons experiencing homelessness (PEH) often use hospital Emergency Department (ED) as the only source of healthcare. The aim of this study was to undertake a systematic review to identify the prevalence, clinical reasons and outcomes in relation to ED visits by PEH.

METHODS

A protocol-led (CRD42020189263) systematic review was conducted using search of MEDLINE, EMBASE, CINAHL and Google Scholar databases. Studies that reported either the prevalence of homelessness in the ED or clinical reasons for presentation to ED by PEH and published in English language were included. Definitions of homelessness used by study authors were accepted.

RESULTS

From the screening of 1349 unique titles, a total of 36 studies were included. Wide variations in the prevalence and key cause of presentations were identified across the studies often linked to differences in country, study setting, disease classification and data collection methods. The proportion of ED visits contributed by PEH ranged from 0.41 to 19.6%. PEH made an average of 0.72 visits to 5.8 visits per person per year in the ED [rate ratio compared to non-homeless 1.63 to 18.75]. Up to a third and quarter of the visits were contributed by alcohol-related diagnoses and substance poisoning respectively. The percentage of PEH who died in the ED ranged from 0.1 to 0.5%.

CONCLUSIONS

Drug-, alcohol- and injury-related presentations dominate the ED visits by PEH. Wide variations in the data were observed in regard to attendance and treatment outcomes. There is a need for prevention actions in the community, integrated discharge and referral pathways between health, housing and social care to minimise frequent usage and improve attendance outcomes.

Waiting for Care: Length of Stay for ED Mental Health Patients by Disposition, Diagnosis, and Region (2009–2015)

Objective

Emergency departments (EDs) face increasing mental health visits on a backdrop of insufficient mental health resources. We study ED length of stay (LOS) and disposition by 1) mental health vs. medical visits; 2) psychiatric vs. substance use visits; and 3) the four regions of the United States. 

Methods

We used weighted data from the National Hospital Ambulatory Medical Care Survey (2009-2015). Visits by patients ages 18-64 were categorized into mental health and medical groups. The mental health group was then subdivided into psychiatric, substance use, and co-occurring disorders. The LOS was compared by disposition. Mental health vs. medical LOS and disposition were examined across four regions of the US.

Results

An estimated 28 million mental health and 526 million medical visits were included in the study. Mental health visits had a median (interquartile range [IQR]) of 3.7 (4.7) hours while medical visits had a median (IQR) of 2.6 (2.7) hours. Mental health compared to medical visits were more likely to result in admission or transfer and to last >6 and >12 hours. Mental health visits resulting in transfer had the longest LOS with a median (IQR) of 6.23 (7.7) hours. Of mental health visit types, co-occurring disorders visits were more likely to be >6 and >12 hours regardless of disposition. Across US regions, there was significant variation in disposition patterns for mental health vs. medical visits. The odds of mental health visits lasting >6 and >12 hours were greatest in the Northeast and the least in the South with a median (IQR) of 4.6 (5.8) hours and 3.3 (4.0) hours, respectively.

Conclusions

Metal health compared to medical visits had longer LOS, especially when the patient had co-occurring disorders or required transfer. Regionally, there is a large variation in disposition for mental health vs. medical visits. This study makes it clear that there are no standards for managing psychiatric emergencies.

Patterns in Medicaid Coverage and Service Utilization Among People with Serious Mental Illnesses

Disruptions in Medicaid adversely affect service use and outcomes among individuals with serious mental illnesses (SMI). A retrospective longitudinal study examined Medicaid coverage and service utilization patterns among individuals with SMI (N = 8358) from 2007 to 2010. Only 36% of participants were continuously enrolled in Medicaid and 20% experienced multiple enrollment disruptions. Mental health diagnosis did not predict continuous coverage; however, individuals with schizophrenia were 19% more likely to have multiple coverage disruptions than those with depression (b = - 0.21; p < 0.01). Single and multiple coverage disruptions were associated with decreased rates of outpatient service days utilized (IRR = 0.77 and 0.65, respectively, p < 0.001) and decreased odds of not using acute care services (OR  0.26 and 0.19, respectively, p < 0.001). Future research should explore mechanisms underlying Medicaid stability and develop interventions that facilitate insurance stability and service utilization.

Characteristics of Nonelderly Adult Health Care Persistent Super Utilizers in Utah

In the United States, the top 1% and top 5% of health care spenders account for 23% and 50% of total health care spending, respectively. These high spenders have been coined the term super utilizers (SU). The aim of this study was to identify the characteristics associated with these patients to aid in developing public health interventions aimed at transitioning patients out of the SU category and thus ultimately helping to control health care costs. The authors utilized the Utah All-Payer Claims Database and Utah Population Database from 2013 to 2015 to identify demographics, comorbid conditions, health care utilization, and cost characteristics of persistent super utilizers (PSU) (≥3 hospitalizations per year for 3 years) of health care compared with persistent nonsuper utilizers (PNSU) (<3 hospitalizations per year for 3 years). Multivariable logistic regression was utilized to identify the characteristics associated with PSU versus PNSU. Higher outpatient/Emergency Department/noninpatient (eg, visits with imaging and Centers for Medicare & Medicaid Services preventive visits) health care utilization and spending, and prevalence of comorbid disease and psychosocial conditions were associated with PSU. In multivariable analysis, factors such as heart disease, chronic kidney disease (CKD), diabetes, alcohol abuse, and depression were statistically significantly associated with higher odds of PSU, with the most noteworthy being CKD (odds ratio [OR] 6.85, 95% confidence interval [95% CI] 5.84-8.02; P < 0.001), alcohol abuse (OR 5.90, 95% CI 4.49-7.69; P < 0.001), and heart diseases (OR 4.41, 95% CI 3.74-5.18; P < 0.001). The annual health care cost of a PSU is about 11.5 times greater than a PNSU ($54,776 vs. $4801; P < 0.001).

How did the first COVID-19 lockdown affect persons with concurrent mental health and substance use disorders in Norway? A qualitative study

BACKGROUND

The outbreak of COVID-19 with its severe social restrictions touched the daily life of most people. While everyday social life becomes difficult for citizens with economic and cultural capital, it becomes even worse for vulnerable groups such as persons with mental health and substance use disorders, who are particularly vulnerable to social exclusion. The aim of this study is to investigate how the first COVID-19 lockdown affected the everyday life and health of persons with co-occurring mental health and substance use disorders.

METHODS

This qualitative study reports data from 17 individual interviews and one focus group of five participants, all with a self-reported mental health and substance use disorder. Interviews were conducted based on a semi-structured interview guide in September and October 2020 in a medium-sized local authority in Norway. Data were analysed using thematic analysis. A reference group of people with varied knowledge and experiences of the phenomenon were involved in study design, recruitment, data generation and analysis.

RESULTS

The analysis identified four interrelated main themes, describing how the first lockdown affected the everyday life and health of persons suffering from a mental health and substance use disorder: (1) The COVID-19 outbreak as a perceived challenge, (2) A decline in mental health and well-being, (3) Increased substance use challenges, and (4) Diverse experiences with health and social services. The results show that people with a co-occurring disorder have challenges with digital tools and/or do not have the appropriate equipment. Further, participants were not concerned about becoming infected themselves, but infecting others.

CONCLUSIONS

Persons with a mental health and substance use disorder face major challenges during the COVID-19 pandemic. There is a need to maintain continuous low-threshold services especially directed towards persons with co-occurring disorders during the pandemic. Furthermore, it is important to improve the digital skills of every service user or offer alternatives to digital consultations and meetings.

Data mining-based clinical profiles of substance use-related emergency department utilizers

OBJECTIVE

Substance-use is a prevalent presentation to the emergency department (ED); however, the clinical characterization of patients who are treated and discharged without admission for further treatment is under-investigated. The study aims to define and characterize the clinical profiles of this patient population.

METHODS

Patients' presentations were examined by clinical data mining (chart review) of ED records of substance use-related events of individuals discharged without admission for further treatment. Records (N = 199) from three major hospitals in New York City from March and June 2017 were randomly sampled with primary diagnosis of alcohol, opioid-related and other psychoactive substance-use presentations. Qualitative thematic coding of clinical presentation with inter-rater reliability was performed. Quantitative distinctive validity tested independence through Pearson's chi-squared and analysis of variance using Fisher's F-test.

RESULTS

Six distinct clinical profiles were identified, including, High Utilizers (chronically intoxicated with comorbid health conditions) (36.7%), Single Episode (20.1%), Service Request (14.1%), Altered Mental Status (13.6%), Overdose (9.0%), and Withdrawal (7.5%). The profiles differed (p < 0.05) in age, housing status, payor, mode of arrival, referral source, index visit time, prescribed treatment, triage acuity level, psychiatric history, and medical history. Differences (p < 0.05) between groups across clinical profiles in age and pain level at triage were observed.

CONCLUSIONS

The identified clinical profiles represent the broad spectrum and complex nature of substance use-related ED utilization, highlighting critical factors of psychosocial and mental-health comorbidities. These findings provide a preliminary foundation to support person-centered interventions to decrease substance use-related ED utilization and to increase engagement/linkage of patients to addiction treatment.

Prevalence of co-occurring mental illness and substance use disorder and association with overdose: a linked data cohort study among residents of British Columbia, Canada

AIMS

To estimate the treated prevalence of mental illness, substance use disorder (SUD) and dual diagnosis and the association between dual diagnosis and fatal and non-fatal overdose among residents of British Columbia (BC), Canada.

DESIGN

A retrospective cohort study using linked health, income assistance, corrections and death records.

SETTING

British Columbia (BC), Canada.

PARTICIPANTS

A total of 921 346 BC residents (455 549 males and 465 797 females) aged 10 years and older.

MEASUREMENTS

Hospital and primary-care administrative data were used to identify a history of mental illness only, SUD only, dual diagnosis or no history of SUD or mental illness (2010-14) and overdoses resulting in medical care (2015-17). We calculated crude incidence rates of non-fatal and fatal overdose by dual diagnosis history. Andersen-Gill and competing risks regression were used to examine the association between dual diagnosis and non-fatal and fatal overdose, respectively, adjusting for age, sex, comorbidities, incarceration history, social assistance, history of prescription opioid and benzodiazepine dispensing and region of residence.

FINDINGS

Of the 921 346 people in the cohort, 176 780 (19.2%), 6147 (0.7%) and 15 269 (1.7%) had a history of mental illness only, SUD only and dual diagnosis, respectively; 4696 (0.5%) people experienced 688 fatal and 6938 non-fatal overdoses. In multivariable analyses, mental illness only, SUD only and dual diagnosis were associated with increased rate of non-fatal [hazard ratio (HR) = 1.8, 95% confidence interval (CI) = 1.6-2.1; HR = 9.0, 95% CI = 7.0-11.5, HR = 8.7, 95% CI = 6.9-10.9, respectively] and fatal overdose (HR = 1.6, 95% CI = 1.3-2.0, HR = 4.3, 95% CI = 2.8-6.5, HR = 4.1, 95% CI = 2.8-6.0, respectively) compared with no history.

CONCLUSIONS

In a large sample of residents of British Columbia (Canada), approximately one in five people had sought care for a substance use disorder or mental illness in the past 5 years. The rate of overdose was elevated in people with a mental illness alone, higher again in people with a substance use disorder alone and highest in people with a dual diagnosis. The adjusted hazard rates were similar for people with substance use disorder only and people with a dual diagnosis.

Assessment and Diagnosis of Mental Illness in EDs Among Individuals Without a Home: Findings from the National Hospital Ambulatory Care Survey

INTRODUCTION

Homeless individuals lack resources for primary healthcare and as a result use the emergency department (ED) as a social safety net. Our primary objective in this study was to identify the differences between features of visits to United States (US) EDs made by patients without a home and patients who live in a private residence presenting with mental health symptoms or no mental health symptoms at triage.

METHODS

Data for this study come from the 2009-2017 National Health and Ambulatory Medical Care Survey, a nationally representative cross-sectional survey of ED visits in the US. We examined differences in waiting time, length of visit, and triage score among homeless patients, and privately housed and nursing home residents. We used logistic regression to determine the odds of receiving a mental health diagnosis. Residence, age, gender, race, urgency, and whether the person was seen in the ED in the previous 72 hours were controlled.

RESULTS

Homeless individuals made up less than 1% of all ED visits during this period. Of these visits, 47.2% resulted in a mental health diagnosis compared to those who live in a private residence. Adjusting for age, race, gender, triage score, and whether the person had been seen in the prior 72 hours, homeless individuals were still six times more likely to receive a mental health diagnosis despite reporting no mental health symptoms compared to individuals who lived in a private residence. Homeless individuals reporting mental health symptoms were two times more likely to receive a mental health diagnosis compared to privately housed and nursing home residents.

CONCLUSIONS

Homeless individuals are more likely to receive a mental health diagnosis in the ED whether or not they present with mental health symptoms at triage. This study suggests that homelessness as a status impacts how these individuals receive care in the ED. Community coordination is needed to expand treatment options for individuals experiencing emergent mental health symptoms.

Emergency Department Visits by Patients with Substance Use Disorder in the United States

INTRODUCTION

We aimed to characterize emergency department (ED) utilization and clinical characteristics of patients with substance use disorder (SUD) seeking emergency care for all reasons.

METHODS

Using 2016-2017 ED data from the National Hospital Ambulatory Medical Care Survey, we investigated demographics, ED resource utilization, and clinical characteristics of patients with SUD vs those without SUD.

RESULTS

Of all adult ED visits (N = 27,609) in the US in 2016-2017, 11.1% of patients had SUD. Among ED patients with SUD, they were mostly non-Hispanic White (62.5%) and were more likely to be male (adjusted odds ratio [aOR] 1.80 confidence interval [CI], 1.66-1.95). Emergency department patients with SUD were also more likely to return to the ED within 72 hours (aOR 1.32, CI, 1.09-1.61) and more likely to be admitted to the hospital (aOR 1.28, CI, 1.14-1.43) and intensive care unit (aOR 1.40, CI, 1.05-1.85).

CONCLUSION

Patients with SUD have specific demographic, socioeconomic, and clinical characteristics associated with their ED visits. These findings highlight the importance of recognizing co-existing SUD as risk factors for increasing morbidity in acutely ill and injured patients, and the potential role of the ED as a site for interventions aimed at reducing harm from SUD.

Media framing of emergency departments: a call to action for nurses and other health care providers

BACKGROUND

As part of a larger study focused on interventions to enhance the capacity of nurses and other health care workers to provide equity-oriented care in emergency departments (EDs), we conducted an analysis of news media related to three EDs. The purpose of the analysis was to examine how media writers frame issues pertaining to nursing, as well as the health and social inequities that drive emergency department contexts, while considering what implications these portrayals hold for nursing practice.

METHODS

We conducted a search of media articles specific to three EDs in Canada, published between January 1, 2018 and May 1, 2019. Media items (N = 368) were coded by story and theme attributes. A thematic analysis was completed to understand how writers in public media present issues pertaining to nursing practice within the ED context.

RESULTS

Two overarching themes were found. First, in ED-related media that portrays health care needs of people experiencing health and social inequities, messaging frequently perpetuates stigmatizing discourses. Second, media writers portray pressures experienced by nurses working in the ED in a way that evades structural determinants of quality of care. Underlying both themes is an absence of perspectives and authorship from practicing nurses themselves.

CONCLUSIONS

We recommend that frontline nurses be prioritized as experts in public media communications. Nurses must be supported to gain critical media skills to contribute to media, to destigmatize the health care needs of people experiencing inequity who attend their practice, and to shed light on the structural causes of pressures experienced by nurses working within emergency department settings.

Clinical characteristics, attendance outcomes and deaths of homeless persons in the emergency department: implications for primary health care and community prevention programmes

OBJECTIVES

Persons experiencing homelessness (PEH) are known to be often excluded from primary health care and community prevention programmes leading to high use of hospital emergency departments (EDs). This study aimed to identify demographic features, clinical characteristics and attendance outcomes of PEH presenting to ED.

STUDY DESIGN

Analysis of routinely collected data set.

METHODS

Clinical presentations and drug prescription data of PEH who presented a major ED in the West Midlands region of England from 2014 to 2019 were extracted and analysed using descriptive and inferential statistics.

RESULTS

During the study period, 3271 of 596,198 presentations were made by PEH; 74% PEH attendees were male. Drug- and alcohol-related conditions, as well as pain and injury constituted the most frequent reasons for presentation, contributing to over half of all presentations. A significantly higher proportion of males (n = 481, 20.3%) presented with drug and alcohol problems than females (n = 93, 11.2%) (P ≤ 0.001). However, pain was the primary reason for presentation for twice as many female patients (n = 189, 22.8%) compared with males (n = 305, 12.9%) (P < 0.001). Nearly one in five left the ED before being assessed and a total of 39 patients (1.2%) died in the ED and 785 (24.0%) required in-patient admissions to the same hospital.

CONCLUSIONS

Drug, alcohol and pain including the need of opioid analgesics constituted the majority of presentations made by PEH in ED. The observed rate of death of PEH in ED is 12 times higher than the general population. A very high proportion of PEH also leave the ED before being treated. Future research should focus on strengthening community interventions, particularly to improve access to those at risk of dual diagnoses of substance misuse and mental health problems. Interventions involving multisector collaborations are needed to improve seamless discharge from ED and minimise repeat attendance. Gender differences in the nature of presentations and ED outcomes needs to be investigated further.

The Checkpoint Program: Collaborative Care to Reduce the Reliance of Frequent Presenters on ED

Introduction:

Growing pressures upon Emergency Departments [ED] call for new ways of working with frequent presenters who, although small in number, place extensive demands on services, to say nothing of the costs and consequences for the patients themselves. EDs are often poorly equipped to address the multi-dimensional nature of patient need and the complex circumstances surrounding repeated presentation. Employing a model of intensive short-term community-based case management, the Checkpoint program sought to improve care coordination for this patient group, thereby reducing their reliance on ED.

Method:

This study employed a single group interrupted time series design, evaluating patient engagement with the program and year-on-year individual differences in the number of ED visits pre and post enrolment. Associated savings were also estimated.

Results:

Prior to intervention, there were two dominant modes in the ED presentation trends of patients. One group had a steady pattern with ≥7 presentations in each of the last four years. The other group had an increasing trend in presentations, peaking in the 12 months immediately preceding enrolment. Following the intervention, both groups demonstrated two consecutive year-on-year reductions. By the second year, and from an overall peak of 22.5 presentations per patient per annum, there was a 53% reduction in presentations. This yielded approximate savings of $7100 per patient.

Discussion:

Efforts to improve care coordination, when combined with proactive case management in the community, can impact positively on ED re-presentation rates, provided they are concerted, sufficiently intensive and embed the principles of integration.

Conclusion:

The Checkpoint program demonstrated sufficient promise to warrant further exploration of its sustainability. However, health services have yet to determine the ideal organisational structures and funding arrangements to support such initiatives.

Self-reported Health Diagnoses and Demographic Correlates With Kratom Use: Results From an Online Survey

OBJECTIVES

To determine whether diagnosed pre-existing health conditions correlate with Kratom demographics and use patterns.

METHODS

A cross-sectional, anonymous US national online survey was conducted among 8049 Kratom users in October, 2016 to obtain demographic, health, and Kratom use pattern information.

RESULTS

People who use Kratom to mitigate illicit drug dependence self-reported less pain and better overall health than individuals who used Kratom for acute/chronic pain. Self-reported improvements in pre-existing mental health symptoms (attention deficit and hyperactivity disorder/attention deficit disorder, anxiety, bipolar disorder, post-traumatic stress disorder, and depression) attributed to Kratom use were greater than those related to somatic symptoms (back pain, rheumatoid arthritis, acute pain, chronic pain, fibromyalgia). Demographic variables, including female sex, older age, employment status, and insurance coverage correlated with increased likelihood of Kratom use.

CONCLUSIONS

Kratom use may serve as a self-treatment strategy for a diverse population of patients with pre-existing health diagnoses. Healthcare providers need to be engaging with patients to address safety concerns and potential limitations of its use in clinical practice for specific health conditions.

Increased Total Cost and Lack of Diagnostic Utility for Emergency Department Visits After ACL Injury

Background:

Patients are commonly evaluated at the emergency department (ED) with acute anterior cruciate ligament (ACL) tears, but providers without orthopaedics training may struggle to correctly diagnose these injuries.

Hypothesis:

It was hypothesized that few patients would be diagnosed with an ACL tear while in the ED and that these patients would be of lower socioeconomic status and more likely to have public insurance.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

The 2017 State Ambulatory Surgery and Services Database (SASD) and State Emergency Department Database (SEDD) from the state of Florida were utilized in this study. Cases with Current Procedural Terminology code 29888 (arthroscopically aided ACL reconstruction [ACLR]) were selected from the SASD, and data from the SEDD were matched to patients who had an ED visit for a knee injury within 120 days before ACLR. Chi-square analysis was used to test for differences in patient and surgical variables between the ED visit and nonvisit patient groups. A generalized linear model was created to model the effect of ED visit on total cost for an ACL injury.

Results:

While controlling for differences in patient characteristics and concomitant procedure usage, a visit to the ED added $4587 in total cost (P < .001). The ED visit cohort contained a greater proportion of patients with Medicaid (20.2% vs 9.1%), patients who were Black (18.4% vs 10.3%), and patients in the lowest income quartile (34.4% vs 25.0%) (P < .001 for all). In the ED visit cohort, 14.4% of patients received an allograft versus 10.1% in the non-ED visit cohort (P = .001) despite having a similar mean age. An ACL sprain was diagnosed in only 29 of the 645 (4.5%) patients who visited the ED.

Conclusion:

Utilizing the ED for care after an ACL injury was expensive, averaging a $4587 increase in total cost associated with ACLR. However, patients rarely left with a definitive diagnosis, with only 4.5% of patients who underwent ACLR being correctly diagnosed with an ACL tear in the ED. This additional cost was levied disproportionately on patients of low socioeconomic status and patients with Medicaid.

A randomized trial of permanent supportive housing for chronically homeless persons with high use of publicly funded services

Objective

To examine whether randomization to permanent supportive housing (PSH) versus usual care reduces the use of acute health care and other services among chronically homeless high users of county‐funded services.

Data Sources

Between 2015 and 2019, we assessed service use from Santa Clara County, CA, administrative claims data for all county‐funded health care, jail and shelter, and mortality.

Study Design

We conducted a randomized controlled trial among chronically homeless high users of multiple systems. We compared postrandomization outcomes from county‐funded systems using multivariate regression analysis.

Data Collection

We extracted encounter data from an integrated database capturing health care at county‐funded facilities, shelter and jails, county housing placement, and death certificates.

Principal Findings

We enrolled 423 participants (199 intervention; 224 control). Eighty‐six percent of those randomized to PSH received housing compared with 36 percent in usual care. On average, the 169 individuals housed by the PSH intervention have remained housed for 28.8 months (92.9 percent of the study follow‐up period). Intervention group members had lower rates of psychiatric ED visits IRR 0.62; 95% CI [0.43, 0.91] and shelter days IRR 0.30; 95% CI [0.17, 0.53], and higher rates of ambulatory mental health services use IRR 1.84; 95% CI [1.43, 2.37] compared to controls. We found no differences in total ED or inpatient use, or jail. Seventy (37 treatment; 33 control) participants died.

Conclusions

The intervention placed and retained frequent user, chronically homeless individuals in housing. It decreased psychiatric ED visits and shelter use, and increased outpatient mental health care, but not medical ED visits or hospitalizations. Limitations included more than one‐third of usual care participants received another form of subsidized housing, potentially biasing results to the null, and loss of power due to high death rates. PSH can house high‐risk individuals and reduce emergent psychiatric services and shelter use. Reductions in hospitalizations may be more difficult to realize.

The Role of Using HEART Score to Risk Stratify Chest Pain Among Emergency Department High Utilizers

The HEART score is used to effectively risk stratify undifferentiated chest pain patients in the Emergency Department (ED). It is unclear whether such risk stratification can be applied among ED high utilizers. We aim to determine the efficacy and safety of using the HEART score to predict 30-day short-term major adverse cardiac events (MACE) in ED high utilizers. We conducted a retrospective, observational study in which ED high utilizers were defined as patients who had four or more ED visits within the past 12 months. ED high utilizers presenting at the study ED with chest pain were enrolled. Patients in which the HEART score was utilized were placed in the HEART group and patients with no HEART scores documented were placed to the usual care group. Hospital admissions and cardiac stress tests performed during the index hospitalizations, and 30-day MACE rates were analyzed and compared between the HEART and usual care groups. From January 1, 2017 to December 31, 2019, a total of 8,315 patient visits from ED high utilizers were enrolled. In the HEART group, 49% of ED visits were admitted with 20% receiving stress tests. A 30-day MACE outcome occurred among 1.4% of visits. In the usual care group, 44% of ED visits were admitted, with only 9% receiving index stress tests and a 1.5% of 30-day MACE occurrence (p=0.727). The study showed that similar short-term MACE outcomes occurred between patients using HEART scores and usual care to risk stratify chest pain among ED high utilizers.

Prevalence of Mental Health Disorders among Individuals Enrolled in an Emergency Response Program for Treatment of Opioid Use Disorder

Background

Psychiatric co-occurring disorders among individuals with opioid use disorder has primarily focused on epidemiological surveys of patients in continuous or long-term treatment, yet little is known about the socio-economically vulnerable who are non-treatment seeking prior to an emergency response.

Methods

We retrospectively analyzed data from patients who had enrolled in a study involving home outreach to patients referred from police, emergency medical services (EMS), or hospital emergency departments following an emergency response. The sample is largely socio-economically vulnerable with high rates of unemployment and uninsured. Eligible consenting patients received an intervention consisting of medication (buprenorphine), behavioral counseling, and peer support. Participants completed semi-structured, psychological instruments to assess current and prior history for both substance use and mental health disorders. We used descriptive statistics to evaluate rates of co-occurring mental health comorbidity.

Results

Among 102 patients (average age = 36.5 years old), approximately 61 (59.8%) reported a prior mental health diagnosis, with 31 (30.3%) currently on medications for their diagnoses. Mood and anxiety disorders were most frequently recorded. Just over half (51%) had received any prior treatment for their substance use. Of those with dual disorders, 67.2% had experienced prior suicidal thoughts, and 63.7% reported polysubstance use of 5 or more substances.

Conclusion

Co-occurring psychiatric disorders, and specifically mood and anxiety disorders, appear to be prevalent in vulnerable populations at an increased rate. Mental health assessments should routinely be performed in the emergency setting and in early stages of treatment.

Dedicated homeless clinics reduce inappropriate emergency department utilization

BACKGROUND

The homeless patient population is known to have a high occurrence of inappropriate emergency department (ED) utilization. The study hospital initiated a dedicated homeless clinic targeting patients experiencing homelessness with a combination of special features. We aim to determine whether this mode of care can reduce inappropriate ED utilization among homeless patients.

METHODS

We conducted a retrospective observational study from July 1, 2017 to Dec 31, 2017. The study enrolled all homeless patients who visited any hospital regular clinic, dedicated homeless clinic, and ED at least once during the study period. ED homeless patients were divided into four groups (A: no clinic visits; B: those who only visited hospital regular clinic; C: those who only visited dedicated homeless clinic; and D: those who visited both hospital regular clinic and dedicated homeless clinic). The New York University algorithm was used to determine appropriate ED utilization. We compared inappropriate ED utilization among patients from these groups. Multivariate logistic regression was used to determine the risks of different clinical visits in association with inappropriate ED utilization.

RESULTS

A total of 16,323 clinic and 8511 ED visits occurred among 5022 unique homeless patients, in which 2450 unique patients were seen in hospital regular clinic, 784 patients in dedicated homeless clinic, 688 patients in both hospital regular clinic and dedicated homeless clinic, and 1110 patients with no clinic visits. Twenty-nine percent (230/784) of patients from dedicated homeless clinic utilized the ED, among which 21% (175/844) of their ED visits were considered inappropriate. In contrast, 40% of patients from hospital regular clinic utilized the ED, among which 29% were inappropriate (P < 0.001). The adjusted odds ratio (OR) was 0.61 (95% confidence interval [CI] = 0.50-0.74, P < 0.001) on dedicated homeless clinic predicting inappropriate ED visits in multivariate logistic regression.

CONCLUSION

Implementing a dedicated homeless clinic with these features can reduce ED inappropriate utilization among patients experiencing homelessness.

Emergency department and early detection of adolescents and young adults at risk of developing mental disorders: an exploratory study

The objective of this study is to assess the potential role of Emergency Department (ED) for early detection of mental disorders. Two cohorts (6,759 subjects aged 14 to 24 accessing ED, 165 subjects with mental disorders) were matched by ID and merged. Primary outcome was the proportion of individuals accessing ED before receiving a diagnosis of mental disorder in Mental Health Service (MHS). Secondary outcomes were age of first access to ED in subjects later accessing to MHS, and time from first ED access to receiving a diagnosis of mental disorder at MHS. We assessed whether gender, severity of ED presentation, and number of ED accesses predicted primary outcome. Almost half of individuals who later developed mental disorders (49.7%) accessed ED before access to MHS. Mean age of first ED contact among those later accessing to MHS was 17.34 (2.1), and ED access preceded access to MHS by 3.68 (2.11) years. Gender and severity of ED presentation were not associated with the access to MHS, while higher number of ED accesses was associated with later access to MHS (OR range: 1.17-1.36, p<0.05). Despite its limitations, the present study suggests ED might represent a contact point for individuals who later access to MHS. Future early detection programs should involve ED in their outreach and screening approaches. Additional studies are needed to assess if subjects earlier accessing to ED are at risk-of-developing or already suffer from a mental disorder, and to validate screening instruments specifically designed for ED.

Variables associated with low, moderate and high emergency department use among patients with substance-related disorders

AIMS

This study identified factors associated with frequency of emergency department (ED) use for medical reasons among patients with substance-related disorders (SRD) in Quebec (Canada) for 2014-15.

METHODS

Participants (n = 4731) were categorized as: 1) low (1 visit/year), 2) moderate (2 visits/year), and 3) high (3+ visits/year) ED users. Independent variables included predisposing, enabling and needs factors based on the Andersen Behavioral Model. Multinomial logistic regression identified associated variables.

RESULTS

Factors positively associated with moderate and high ED use included adjustment disorders, suicidal behavior, alcohol-induced disorders, less urgent to non-urgent illness acuity, referral to local health community services centers (LHCSC) at discharge, and living in a materially deprived area. Factors positively associated with high ED use only included anxiety disorders, alcohol use disorders, drug use disorders, chronic physical illness, subacute problems, prior ED use for MD and/or SRD, prior LHCSC medical interventions, physician consultation within one month after discharge, living in very deprived or middle-class areas, and, negatively, being hospitalized for medical reasons in second ED visit. Moderate ED use only was negatively associated with alcohol intoxication and being referred to a GP at ED discharge.

CONCLUSIONS

Compared to low ED users, most high users with SRD were men presenting more complex and severe conditions. They visited ED mainly for subacute or non-urgent problems. Compared to low ED users, most moderate users had alcohol-induced disorders, less alcohol intoxication, and acute common MD. They visited ED mainly for non-urgent care. Diverse strategies should be implemented to reduce ED visits, targeting each group.

Homelessness in mental illness: Opportunities & prospects in the Indian context

Homelessness is considered a serious public health concern. Bidirectional relationship has been established between homelessness and mental illness by research studies and its association with compromised well-being, poor quality of life and low productivity. Recent legislative enactments in India have necessitated on the part of the state to address issues related to the rights of persons with mental illness including shelter and housing. Therefore, it becomes imperative to discuss opportunities and prospects in India towards rehabilitating homeless mentally ill in context of existing programs, policies and legislations.
