Emergency Medicine Research Priorities for Early Intervention for Substance Use Disorders

Patient perspectives on emergency department initiation of medication for alcohol use disorder

OBJECTIVE

Alcohol use disorder (AUD) is a leading cause of preventable death and is a frequent diagnosis in the emergency department (ED). Treatment in the ED, however, typically focuses on managing the sequelae of AUD, such as acute withdrawal, rather than addressing the underlying addiction. For many patients, these ED encounters are a missed opportunity to connect with medication for AUD. In 2020, our ED created a pathway to offer patients with AUD treatment with naltrexone (NTX) during their ED visit. The aim of this study was to identify what barriers and facilitators patients perceive to NTX initiation in the ED.

METHODS

Adopting the theoretical framework of the behavior change wheel (BCW), we conducted qualitative interviews with patients to elicit their perspectives on ED initiation of NTX. Interviews were coded and analyzed using both inductive and deductive approaches. Themes were categorized according to patients' capabilities, opportunities, and motivations. Barriers were then mapped through the BCW to design interventions that will improve our treatment pathway.

RESULTS

Twenty-eight patients with AUD were interviewed. Facilitators of accepting NTX included having recently experienced sequelae of AUD, rapid management of withdrawal symptoms by the ED provider, having a choice between intramuscular and oral formulations of the medication, and experiencing positive interactions in the ED that destigmatized the patient's AUD. Barriers to accepting treatment included lack of provider knowledge about NTX, dependence on alcohol as self-treatment for psychiatric trauma and physical pain, perceived discriminatory treatment and stigma about AUD, aversion to potential side effects, and lack of access to continued treatment.

CONCLUSIONS

Initiation of treatment of AUD with NTX in the ED is acceptable to patients and can be facilitated by knowledgeable ED providers who create a destigmatizing environment, effectively manage withdrawal symptoms, and connect patients to providers who will continue treatment.

Addressing cortex dysregulation in youth through brain health check coaching and prophylactic brain development

The Carter Center has estimated that the addiction crisis in the United States (US), if continues to worsen at the same rate, may cost the country approximately 16 trillion dollars by 2030. In recent years, the well-being of youth has been compromised by not only the coronavirus disease 2019 pandemic but also the alarming global opioid crisis, particularly in the US. Each year, deadly opioid drugs claim hundreds of thousands of lives, contributing to an ever-rising death toll. In addition, maternal usage of opioids and other drugs during pregnancy could compromise the neurodevelopment of children. A high rate of DNA polymorphic antecedents compounds the occurrence of epigenetic insults involving methylation of specific essential genes related to normal brain function. These genetic antecedent insults affect healthy DNA and mRNA transcription, leading to a loss of proteins required for normal brain development and function in youth. Myelination in the frontal cortex, a process known to extend until the late 20s, delays the development of proficient executive function and decision-making abilities. Understanding this delay in brain development, along with the presence of potential high-risk antecedent polymorphic variants or alleles and generational epigenetics, provides a clear rationale for embracing the Brain Research Commission's suggestion to mimic fitness programs with an adaptable brain health check (BHC). Implementing the BHC within the educational systems in the US and other countries could serve as an effective initiative for proactive therapies aimed at reducing juvenile mental health problems and eventually criminal activities, addiction, and other behaviors associated with reward deficiency syndrome.

Integrating substance use peer support and screening brief intervention and referral to treatment services in the emergency department: a descriptive study of the ED leads program

BACKGROUND

The ED Leads program was introduced to 11 emergency departments (EDs) within New York City public hospitals from 2018 to 2019 to address a need for addiction support services in the ED. The purpose of this study is to (i) describe the ED Leads blended licensed-clinician and peer counselor team model in the ED at three hospitals, (ii) provide a descriptive analysis of patient engagement and referrals to substance use disorder (SUD) care post-intervention, and (iii) highlight potential barriers and facilitators to implementing the model.

METHODS

The program intended to combine Screening Brief Intervention and Referral to Treatment and peer support services. The authors analyzed electronic medical records data for patients encountered by ED Leads in the first 120 days of program launch. Data included the outcome of an encounter when a patient was engaged with one or both staff types, and 7-day attendance at an SUD treatment appointment when a patient accepted a referral within the 11-hospital system.

RESULTS

There were 1785 patients approached by ED Leads staff during the study period. Engagement differed by staff type and patient demographics, and encounter outcomes varied significantly by hospital. Eighty-four percent (N = 1503) of patients who were approached engaged with at least one staff type, and 6% (N = 86) engaged with both. Patients were predominantly male (N = 1438, 81%) with an average age of 45 (SD = 13), and enrolled in Medicaid (N = 1062, 59%). A majority (N = 801, 45%) had alcohol use disorder. Of the patients who accepted a referral within the system (N = 433), 63% received treatment services within 7 days of the ED Leads encounter, a majority at detoxification treatment (N = 252, 58%).

CONCLUSIONS

This study describes the potential value and challenges of implementing a blended peer counselor and licensed clinician model in the ED to provide SUD services. While teams provided a high volume of referrals and the analysis of post-intervention treatment follow up is promising, the blended team model was not fully realized, making it difficult to assess the benefits of this combined service. Further research might examine patient outcomes among ED patients who are offered services by both a peer counselor and licensed clinician.

The impact of polysubstance use patterns on engagement of substance use disorder treatment among emergency department patients at high risk of opioid overdose

Background

Substance use patterns are diverse, and multiple substances are often involved in fatal and nonfatal overdoses. Additionally, polysubstance use is associated with greater difficulty accessing and remaining in substance use disorder (SUD) treatment. The aim of this study was to identify substance use patterns and determine their association with SUD treatment engagement among emergency department (ED) patients at risk of opioid overdose.

Methods

This was a sub-analysis of a randomized controlled trial comparing two behavioral interventions for individuals at two EDs in Rhode Island from 2018 to 2021. Past six-month substance use frequency for eight substances plus injection drug use was self-reported at trial enrollment, and SUD treatment engagement within 90 days after enrollment was obtained using administrative data linkages. Latent class analysis identified substance use patterns and multivariable log-binomial models estimated the association with SUD treatment engagement.

Results

Among 607 participants, there were four substance use patterns: 1) low reported use (n = 295), 2) frequent injection and heroin use (n = 131), 3) high frequency broad polysubstance use (n = 62), and 4) low frequency broad polysubstance use (n = 119). Compared to participants with the low reported use pattern, those with the frequent injection and heroin pattern had a greater likelihood of SUD treatment engagement (adjusted risk ratio = 1.28; 95% confidence interval = 1.02-1.61).

Conclusions

Distinct and meaningful polysubstance use patterns showed differential SUD treatment engagement after ED discharge. Nuanced relationships between substance use patterns and treatment highlight the necessity for tailored harm reduction, treatment, and recovery services.

Implementation of a hospital-based intervention for MOUD initiation and referral to a Bridge Clinic for opioid use disorder

INTRODUCTION

Individuals struggling with opioid use disorder (OUD) utilize the adult emergency department (ED) and psychiatric emergency department at high rates. In 2019, Vanderbilt University Medical Center created a system for individuals identified in the emergency department with OUD to transition care to a Bridge Clinic for up to three months of comprehensive behavioral health treatment, alongside primary care, infectious diseases, and pain management, regardless of their insurance status.

METHODS

We conducted 20 interviews with patients enrolled in treatment in our Bridge Clinic and 13 providers in the psychiatric emergency department and emergency department. Our provider interviews focused on understanding experiences identifying people with OUD and referring them to care at the Bridge Clinic. Our patient interviews focused on understanding their experiences of care-seeking, the referral process, and their satisfaction with treatment at the Bridge Clinic.

RESULTS

Our analysis generated 3 major themes around patient identification, referral, and quality of care from providers and patients. The study found general agreement between both groups around the high quality of care delivered in the Bridge Clinic compared with OUD treatment at nearby treatment facilities, specifically because it offered a stigma-free environment for the delivery of medication for addiction therapy and psychosocial support. Providers highlighted the lack of a systematic strategy for identifying people with OUD in an ED setting. They also found the referral process cumbersome because it could not be done through EPIC and there were limited patient slots available. In contrast, patients reported a smooth and simple referral from the ED to the Bridge Clinic.

CONCLUSIONS

Creating a Bridge Clinic for comprehensive OUD treatment at a large university medical center has been challenging but has resulted in the creation of a comprehensive care system that prioritizes quality care. Funding to increase the number of patient slots available, coupled with an electronic system of patient referral, will increase the reach of the program to some of Nashville's most vulnerable constituents.

Contemporary Practices for Medical Evaluation of the Psychiatric Patient in the Emergency Department

Although emergency department (ED) visits for patients with mental illness are frequent, medical evaluation (i.e., "medical screening") of patients presenting with psychiatric complaints is inconsistent. This may largely be related to differing goals for medical screening, which often vary according to specialty. Although emergency physicians typically focus on stabilization of life-threatening diseases, psychiatrists tend to believe that care in the ED is more comprehensive, which often places the two fields at odds. The authors discuss the concept of medical screening, review the literature on this topic, and offer a clinically oriented update to the 2017 American Association for Emergency Psychiatry consensus guidelines on medical evaluation of the adult psychiatric patient in the ED.

Research priority setting in emergency care: A scoping review

Objective

Priority areas for emergency care research are emerging and becoming ever more important. The objectives of this scoping review were to (1) provide a comprehensive overview of published emergency care priority‐setting studies by collating and comparing priority‐setting methodology and (2) describe the resulting research priorities identified.

Methods

The Joanna Briggs Institute methodological framework was used. Inclusion criteria were peer‐review articles available in English, published between January 1, 2008 and March 31, 2019 and used 2 or more search terms. Five databases (Scopus, AustHealth, EMBASE, CINAHL, and Ovid MEDLINE) were searched. REporting guideline for PRIority SEtting of health research (REPRISE) criteria were used to assess the quality of evidence of included articles.

Results

Forty‐five studies were included. Fourteen themes for emergency care research were considered within 3 overarching research domains: emergency populations (pediatrics, geriatrics), emergency care workforce and processes (nursing, shared decision making, general workforce, and process), and emergency care clinical areas (imaging, falls, pain management, trauma care, substance misuse, infectious diseases, mental health, cardiology, general clinical care). Variation in the reporting of research priority areas was evident. Priority areas to drive the global agenda for emergency care research are limited given the country and professional group‐specific context of existing studies.

Conclusion

This comprehensive summary of generated research priorities across emergency care provides insight into current and future research agendas. With the nature of emergency care being inherently broad, future priorities may warrant population (eg, children, geriatrics) or subspecialty (eg, trauma, toxicology, mental health) focus and be derived using a rigorous framework and patient engagement.

Implementing a text-messaging intervention for unhealthy alcohol use in emergency departments: protocol for implementation strategy development and a pilot cluster randomized implementation trial

BACKGROUND

Unhealthy alcohol use (UAU) is a leading cause of premature mortality among adults in the USA. Emergency departments (EDs) are key intervention settings for UAU but often have limited time and resources. One low-burden, scalable approach to address UAU is text-messaging interventions. Despite strong research support and promise for scalability, there is little research on how to implement such interventions in healthcare settings. The process of providers making them available to patients in an efficient way within already busy and overburdened ED workflows and patients adopting them remains a new area of research. The purpose of this three-phase study is to develop and test an implementation strategy for UAU text-messaging interventions in EDs.

METHOD

Our first aim is to examine barriers and facilitators to staff offering and patients accepting a text-messaging intervention in the ED using an explanatory, sequential mixed methods approach. We will examine alcohol screening data in the electronic health records of 17 EDs within a large integrated health system in the Northeast and conduct surveys among chairpersons in each. This data will be used to purposively sample 4 EDs for semi-structured interviews among 20 clinical staff, 20 patients, and 4 chairpersons. Our second aim is to conduct a stakeholder-engaged intervention mapping process to develop a multi-component implementation strategy for EDs. Our third aim is to conduct a mixed method 2-arm cluster randomized pilot study in 4 EDs that serve ~11,000 UAU patients per year to assess the feasibility, acceptability, and preliminary effectiveness of the implementation strategy. The Integrated Promoting Action on Research Implementation in Health Services framework will guide study activities.

DISCUSSION

Low-burden technology, like text messaging, along with targeted implementation support and strategies driven by identified barriers and facilitators could sustain large-scale ED-based alcohol screening programs and provide much needed support to patients who screen positive while reducing burden on EDs. The proposed study would be the first to develop and test this targeted implementation strategy and will prepare for a larger, fully powered hybrid effectiveness-implementation trial. Findings may also be broadly applicable to implementation of patient-facing mobile health technologies.

TRIAL REGISTRATION

This study was registered at ClinicalTrials.gov (NCT05350878) on 4/28/2022.

Provider perspectives on emergency department initiation of medication assisted treatment for alcohol use disorder

Background

Alcohol use disorder (AUD) is ubiquitous and its sequelae contribute to high levels of healthcare utilization, yet AUD remains undertreated. The ED encounter represents a missed opportunity to initiate medication assisted treatment (MAT) for patients with AUD. The aims of this study are to identify barriers and facilitators to the treatment of AUD in the ED, and to design interventions to address identified barriers.

Methods

Using an implementation science approach based on the Behavior Change Wheel framework, we conducted qualitative interviews with staff to interrogate their perspectives on ED initiation of AUD treatment. Subjects included physicians, nurses, nurse practitioners, clinical social workers, and pharmacists. Interviews were thematically coded using both inductive and deductive approaches and constant comparative analysis. Themes were further categorized as relating to providers’ capabilities, opportunities, or motivations. Barriers were then mapped to corresponding intervention functions.

Results

Facilitators at our institution included time allotted for continuing education, the availability of clinical social workers, and favorable opinions of MAT based on previous experiences implementing buprenorphine for opioid use disorder. Capability barriers included limited familiarity with naltrexone and difficulty determining which patients are candidates for therapy. Opportunity barriers included the limited supply of naltrexone and a lack of clarity as to who should introduce naltrexone and assess readiness for change. Motivation barriers included a sense of futility in treating patients with AUD and stigmas associated with alcohol use. Evidence-based interventions included multi-modal provider education, a standardized treatment algorithm and order set, selection of clinical champions, and clarification of roles among providers on the team.

Conclusions

A large evidence-practice gap exists for the treatment of AUD with Naltrexone, and the ED visit is a missed opportunity for intervention. ED providers are optimistic about implementing AUD treatment in the ED but described many barriers, especially related to knowledge, clarification of roles, and stigma associated with AUD. Applying a formal implementation science approach guided by the Behavior Change Wheel allowed us to transform qualitative interview data into evidence-based interventions for the implementation of an ED-based program for the treatment of AUD.

Do adolescents and young adults accessing the Emergency Room with substance use receive poor therapeutic indications at discharge? An observational retrospective study

PURPOSE

Emergency rooms (ERs) are usually the first point of contact with mental health services for adolescents with Substance Use Disorders (SUDs). However, only a minority of them receives proper treatment and follow-up indications, increasing the risk of relapses and poor prognosis. In this perspective, we sought to characterize and compare socio-demographic and clinical characteristics of adolescents with vs without SUDs accessing the ER, assessing potential differences in terms of discharge instructions.

METHODS

A sample of 557 ER accesses of patients aged 15-25 years old in need of a psychiatric evaluation or with a psychiatric diagnosis at discharge was retrospectively analyzed. Patients were divided in two subgroups according to the presence of SUDs.

RESULTS

About 32.1% of patients had SUDs when accessing the ER. Among these, 62% were unknown to any psychiatric services and 57% were at their psychiatric onset. Nevertheless, considering discharge instructions, patients with current substance use received less therapeutic indication or were less frequently referred to psychiatric facilities, than those without substance use (57.8% vs 42.2%, P = .002).

CONCLUSIONS

Substance abuse is strongly linked to psychopathology and ER accesses in young patients. However, we observed a large rate of SUDs patients unknown by any specialized mental health service, who received poor therapeutic and follow-up instructions at discharge. Improving communication between ER operators and young patients with SUDs could longitudinally reduce the risk of addiction and related disability, morbidity and mortality.

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

STUDY OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

How Emergency Physicians Approach Refusal of Observation after Naloxone Resuscitation

BACKGROUND

Patients who are resuscitated with naloxone frequently refuse a period of observation, even though they may be suffering from a variety of medical and psychiatric comorbidities. Emergency physicians (EPs) are then confronted with the challenge of how best to serve patients' interests while respecting autonomy.

OBJECTIVES

We sought to characterize how EPs think about this kind of dilemma and the strategies they use to resolve them.

METHODS

We conducted qualitative semi-structured interviews with a convenience sample of 59 emergency physicians attending the American College of Emergency Physicians' Scientific Assembly in October 2018. Three case vignettes highlighting different clinical and ethical features served as prompts. Interviews were analyzed using a constant comparative method to identify patterns of responses and derive key themes.

RESULTS

Across the vignettes, EPs demonstrated diverse approaches to observation, assessing decision-making capacity and encouraging compliance. Some EPs refused to comply with a patient's wishes even when they had determined a patient demonstrated capacity. Conversely, a few EPs were willing to allow patients to leave the emergency department (ED) without assessing capacity, or despite determining that the patient lacked capacity. Common reasons for complying with patients' demands were concerns about the patients' rights and concerns about the safety of staff. Most physicians interviewed reported no institutional guidelines or education on the topic, and many physicians expressed an interest in providing medication for addiction treatment in the ED.

CONCLUSIONS

EPs approach this clinical and ethical dilemma in widely divergent ways. Consensus about strategies for navigating patients' wishes relative to clinical concerns are needed to help EPs manage these challenging cases.

Opportunities for Research in Mental Health Emergencies: Executive Summary and Methodology

Introduction

Despite the ever-increasing numbers of mental health patients presenting to United States emergency departments, there are large gaps in knowledge about acute care of the behavioral health patient. To address this important problem, the Coalition on Psychiatric Emergencies convened a research consensus conference in December 2016 consisting of clinical researchers, clinicians from emergency medicine, psychiatry and psychology, and representatives from governmental agencies and patient advocacy groups.

Methods

Participants used a standardized methodology to select and rank research questions in the order of importance to both researchers and patients.

Results

Three working groups (geriatrics, substance use disorders, and psychosis) reached consensus on 26 questions within their respective domains. These questions are summarized in this document.

Conclusion

The research consensus conference is the first of its kind to include non-clinicians in helping identify knowledge gaps in behavioral emergencies. It is hoped that these questions will prove useful to prioritize future research within the specialty.
