Interrupted Time Series of User-centered Clinical Decision Support Implementation for Emergency Department-initiated Buprenorphine for Opioid Use Disorder

Clinical decision support systems in addiction and concurrent disorders: A systematic review and meta-analysis

INTRODUCTION

This review aims to synthesise the literature on the efficacy, evolution, and challenges of implementing Clincian Decision Support Systems (CDSS) in the realm of mental health, addiction, and concurrent disorders.

METHODS

Following PRISMA guidelines, a systematic review and meta-analysis were performed. Searches conducted in databases such as MEDLINE, Embase, CINAHL, PsycINFO, and Web of Science through 25 May 2023, yielded 27,344 records. After necessary exclusions, 69 records were allocated for detailed synthesis. In the examination of patient outcomes with a focus on metrics such as therapeutic efficacy, patient satisfaction, and treatment acceptance, meta-analytic techniques were employed to synthesise data from randomised controlled trials.

RESULTS

A total of 69 studies were included, revealing a shift from knowledge-based models pre-2017 to a rise in data-driven models post-2017. The majority of models were found to be in Stage 2 or 4 of maturity. The meta-analysis showed an effect size of -0.11 for addiction-related outcomes and a stronger effect size of -0.50 for patient satisfaction and acceptance of CDSS.

DISCUSSION

The results indicate a shift from knowledge-based to data-driven CDSS approaches, aligned with advances in machine learning and big data. Although the immediate impact on addiction outcomes is modest, higher patient satisfaction suggests promise for wider CDSS use. Identified challenges include alert fatigue and opaque AI models.

CONCLUSION

CDSS shows promise in mental health and addiction treatment but requires a nuanced approach for effective and ethical implementation. The results emphasise the need for continued research to ensure optimised and equitable use in healthcare settings.

The role of information systems in emergency department decision-making-a literature review

OBJECTIVES

Healthcare providers employ heuristic and analytical decision-making to navigate the high-stakes environment of the emergency department (ED). Despite the increasing integration of information systems (ISs), research on their efficacy is conflicting. Drawing on related fields, we investigate how timing and mode of delivery influence IS effectiveness. Our objective is to reconcile previous contradictory findings, shedding light on optimal IS design in the ED.

MATERIALS AND METHODS

We conducted a systematic review following PRISMA across PubMed, Scopus, and Web of Science. We coded the ISs' timing as heuristic or analytical, their mode of delivery as active for automatic alerts and passive when requiring user-initiated information retrieval, and their effect on process, economic, and clinical outcomes.

RESULTS

Our analysis included 83 studies. During early heuristic decision-making, most active interventions were ineffective, while passive interventions generally improved outcomes. In the analytical phase, the effects were reversed. Passive interventions that facilitate information extraction consistently improved outcomes.

DISCUSSION

Our findings suggest that the effectiveness of active interventions negatively correlates with the amount of information received during delivery. During early heuristic decision-making, when information overload is high, physicians are unresponsive to alerts and proactively consult passive resources. In the later analytical phases, physicians show increased receptivity to alerts due to decreased diagnostic uncertainty and information quantity. Interventions that limit information lead to positive outcomes, supporting our interpretation.

CONCLUSION

We synthesize our findings into an integrated model that reveals the underlying reasons for conflicting findings from previous reviews and can guide practitioners in designing ISs in the ED.

Factors associated with frequent buprenorphine / naloxone initiation in a national survey of Canadian emergency physicians

OBJECTIVE

To identify individual and site-related factors associated with frequent emergency department (ED) buprenorphine/naloxone (BUP) initiation. BUP initiation, an effective opioid use disorder (OUD) intervention, varies widely across Canadian EDs.

METHODS

We surveyed emergency physicians in 6 Canadian provinces from 2018 to 2019 using bilingual paper and web-based questionnaires. Survey domains included BUP-related practice, demographics, attitudes toward BUP, and site characteristics. We defined frequent BUP initiation (the primary outcome) as at least once per month, high OUD prevalence as at least one OUD patient per shift, and high OUD resources as at least 3 out of the following 5 resources: BUP initiation pathways, BUP in ED, peer navigators, accessible addiction specialists, and accessible follow-up clinics. We excluded responses from sites with <50% participation (to minimize non-responder bias) and those missing the primary outcome. We used univariate analysis to identify associations between frequent BUP initiation and factors of interest, stratifying by OUD prevalence.

RESULTS

We excluded 3 responses for missing BUP initiation frequency and 9 for low response rate at one ED. Of the remaining 649 respondents from 34 EDs, 374 (58%) practiced in metropolitan areas, 384 (59%) reported high OUD prevalence, 312 (48%) had high OUD resources, and 161 (25%) initiated BUP frequently. Age, gender, board certification and years in practice were not associated with frequent BUP initiation. Site-specific factors were associated with frequent BUP initiation (high OUD resources [OR 6.91], high OUD prevalence [OR 4.45], and metropolitan location [OR 2.39],) as were individual attitudinal factors (willingness, confidence, and responsibility to initiate BUP.) Similar associations persisted in the high OUD prevalence subgroup.

CONCLUSIONS

Individual attitudinal and site-specific factors were associated with frequent BUP initiation. Training to increase physician confidence and increasing OUD resources could increase BUP initiation and benefit ED patients with OUD.

Harm reduction strategies in acute care for people who use alcohol and/or drugs: A scoping review

BACKGROUND

People who use alcohol and/or drugs (PWUAD) are at higher risk of infectious disease, experiencing stigma, and recurrent hospitalization. Further, they have a higher likelihood of death once hospitalized when compared to people who do not use drugs and/or alcohol. The use of harm reduction strategies within acute care settings has shown promise in alleviating some of the harms experienced by PWUAD. This review aimed to identify and synthesize evidence related to the implementation of harm reduction strategies in acute care settings.

METHODS

A scoping review investigating harm reduction strategies implemented in acute care settings for PWUAD was conducted. A search strategy developed by a JBI-trained specialist was used to search five databases (Medline, Embase, CINAHL, PsychInfo and Scopus). Screening of titles, abstracts and full texts, and data extraction was done in duplicate by two independent reviewers. Discrepancies were resolved by consensus or with a third reviewer. Results were reported narratively and in tables. Both patients and healthcare decision makers contributing to the development of the protocol, article screening, synthesis and feedback of results, and the identification of gaps in the literature.

FINDINGS

The database search identified 14,580 titles, with 59 studies included in this review. A variety of intervention modalities including pharmacological, decision support, safer consumption, early overdose detection and turning a blind eye were identified. Reported outcome measures related to safer use, managed use, and conditions of use. Reported barriers and enablers to implementation related to system and organizational factors, patient-provider communication, and patient and provider perspectives.

CONCLUSION

This review outlines the types of alcohol and/or drug harm reduction strategies, which have been evaluated and/or implemented in acute care settings, the type of outcome measures used in these evaluations and summarizes key barriers and enablers to implementation. This review has the potential to serve as a resource for future harm reduction evaluation and implementation efforts in the context of acute care settings.

21st century (clinical) decision support in nursing and allied healthcare. Developing a learning health system: a reasoned design of a theoretical framework

In this paper, we present a framework for developing a Learning Health System (LHS) to provide means to a computerized clinical decision support system for allied healthcare and/or nursing professionals. LHSs are well suited to transform healthcare systems in a mission-oriented approach, and is being adopted by an increasing number of countries. Our theoretical framework provides a blueprint for organizing such a transformation with help of evidence based state of the art methodologies and techniques to eventually optimize personalized health and healthcare. Learning via health information technologies using LHS enables users to learn both individually and collectively, and independent of their location. These developments demand healthcare innovations beyond a disease focused orientation since clinical decision making in allied healthcare and nursing is mainly based on aspects of individuals' functioning, wellbeing and (dis)abilities. Developing LHSs depends heavily on intertwined social and technological innovation, and research and development. Crucial factors may be the transformation of the Internet of Things into the Internet of FAIR data & services. However, Electronic Health Record (EHR) data is in up to 80% unstructured including free text narratives and stored in various inaccessible data warehouses. Enabling the use of data as a driver for learning is challenged by interoperability and reusability.To address technical needs, key enabling technologies are suitable to convert relevant health data into machine actionable data and to develop algorithms for computerized decision support. To enable data conversions, existing classification and terminology systems serve as definition providers for natural language processing through (un)supervised learning.To facilitate clinical reasoning and personalized healthcare using LHSs, the development of personomics and functionomics are useful in allied healthcare and nursing. Developing these omics will be determined via text and data mining. This will focus on the relationships between social, psychological, cultural, behavioral and economic determinants, and human functioning.Furthermore, multiparty collaboration is crucial to develop LHSs, and man-machine interaction studies are required to develop a functional design and prototype. During development, validation and maintenance of the LHS continuous attention for challenges like data-drift, ethical, technical and practical implementation difficulties is required.

Optimizing electronic blood ordering and supporting administration workflows to improve blood utilization in the pediatric hospital setting

BACKGROUND

Red blood cell wastage occurs when blood is discarded rather than transfused, and ineffective ordering results in unnecessary crossmatch procedures. We describe how a multimodal approach to redesigning electronic ordering tools improved blood utilization in a pediatric inpatient setting and how using innovative application of time series data analysis provides insights into intervention effectiveness, which can guide future process improvement cycles.

METHODS

A multidisciplinary team used best practices and Toyota Production System methodology to redesign electronic blood ordering and improve administration processes. We analyzed crossmatch to transfusion ratio and red blood cell wastage time series data extracted from our laboratory information system and electronic health record. We used changepoint analysis to identify statistically discernible breaks in each time series, compatible with known interventions. We performed causal impact analysis on red blood cell wastage time series data to estimate blood wastage avoided due to the interventions.

RESULTS

Changepoint analysis estimated an 11% decrease in crossmatch to transfusion ratio and a 77% decrease in red blood cell monthly wastage rate during the intervention period. Causal impact analysis estimated a 61% reduction in expected wastage compared to the scenario if the interventions had not occurred.

DISCUSSION

Our results show that electronic health record design is an important factor in reducing waste and preventing unnecessary crossmatching, and that time series analysis can be a useful tool for evaluating the long-term impact of each stage of intervention in a longitudinal process redesign effort for the purpose of effectively targeting future improvement efforts.

Impact of Universal Screening and Automated Clinical Decision Support for the Treatment of Opioid Use Disorder in Emergency Departments: A Difference-in-Differences Analysis

STUDY OBJECTIVE

Emergency department (ED)-initiated buprenorphine improves outcomes in patients with opioid use disorder; however, adoption varies widely. To reduce variability, we implemented a nurse-driven triage screening question in the electronic health record to identify patients with opioid use disorder, followed by targeted electronic health record prompts to measure withdrawal and guide next steps in management, including initiation of treatment. Our objective was to assess the impact of screening implementation in 3 urban, academic EDs.

METHODS

We conducted a quasiexperimental study of opioid use disorder-related ED visits using electronic health record data from January 2020 to June 2022. The triage protocol was implemented in 3 EDs between March and July 2021, and 2 other EDs in the health system served as controls. We evaluated changes in treatment measures over time and used a difference-in-differences analysis to compare outcomes in the 3 intervention EDs with those in the 2 controls.

RESULTS

There were 2,462 visits in the intervention hospitals (1,258 in the preperiod and 1,204 in the postperiod) and 731 in the control hospitals (459 in the preperiod and 272 in the postperiod). Patient characteristics within the intervention and control EDs were similar across the time periods. Compared with the control hospitals, the triage protocol was associated with a 17% greater increase in withdrawal assessment, using the Clinical Opioid Withdrawal Scale (COWS) (95% CI 7 to 27). Buprenorphine prescriptions at discharge also increased by 5% (95% CI 0% to 10%), and naloxone prescriptions increased by 12% points (95% CI 1% to 22%) in the intervention EDs relative to controls.

CONCLUSION

An ED triage screening and treatment protocol led to increased assessment and treatment of opioid use disorder. Protocols designed to make screening and treatment the default practice have promise in increasing the implementation of evidence-based treatment ED opioid use disorder care.

The value of a spaceflight clinical decision support system for earth-independent medical operations

As NASA prepares for crewed lunar missions over the next several years, plans are also underway to journey farther into deep space. Deep space exploration will require a paradigm shift in astronaut medical support toward progressively earth-independent medical operations (EIMO). The Exploration Medical Capability (ExMC) element of NASA's Human Research Program (HRP) is investigating the feasibility and value of advanced capabilities to promote and enhance EIMO. Currently, astronauts rely on real-time communication with ground-based medical providers. However, as the distance from Earth increases, so do communication delays and disruptions. Moreover, resupply and evacuation will become increasingly complex, if not impossible, on deep space missions. In contrast to today's missions in low earth orbit (LEO), where most medical expertise and decision-making are ground-based, an exploration crew will need to autonomously detect, diagnose, treat, and prevent medical events. Due to the sheer amount of pre-mission training required to execute a human spaceflight mission, there is often little time to devote exclusively to medical training. One potential solution is to augment the long duration exploration crew's knowledge, skills, and abilities with a clinical decision support system (CDSS). An analysis of preliminary data indicates the potential benefits of a CDSS to mission outcomes when augmenting cognitive and procedural performance of an autonomous crew performing medical operations, and we provide an illustrative scenario of how such a CDSS might function.

Hospital-based clinicians lack knowledge and comfort in initiating medications for opioid use disorder: opportunities for training innovation

BACKGROUND

Hospital-based clinicians infrequently initiate medications for opioid use disorder (MOUD) for hospitalized patients. Our objective was to understand hospital-based clinicians' knowledge, comfort, attitudes, and motivations regarding MOUD initiation to target quality improvement initiatives.

METHODS

General medicine attending physicians and physician assistants at an academic medical center completed questionnaires eliciting barriers to MOUD initiation, including knowledge, comfort, attitudes and motivations regarding MOUD. We explored whether clinicians who had initiated MOUD in the prior 12 months differed in knowledge, comfort, attitudes, and motivations from those who had not.

RESULTS

One-hundred forty-three clinicians completed the survey with 55% reporting having initiated MOUD for a hospitalized patient during the prior 12 months. Common barriers to MOUD initiation were: (1) Not enough experience (86%); (2) Not enough training (82%); (3) Need for more addiction specialist support (76%). Overall, knowledge of and comfort with MOUD was low, but motivation to address OUD was high. Compared to MOUD non-initiators, a greater proportion of MOUD initiators answered knowledge questions correctly, agreed or strongly agreed that they wanted to treat OUD (86% vs. 68%, p = 0.009), and agreed or strongly agreed that treatment of OUD with medication was more effective than without medication (90% vs. 75%, p = 0.022).

CONCLUSIONS

Hospital-based clinicians had favorable attitudes toward MOUD and are motivated to initiate MOUD, but they lacked knowledge of and comfort with MOUD initiation. To increase MOUD initiation for hospitalized patients, clinicians will need additional training and specialist support.

The effectiveness of a noninterruptive alert to increase prescription of take-home naloxone in emergency departments

OBJECTIVE

Opioid-related overdose (OD) deaths continue to increase. Take-home naloxone (THN), after treatment for an OD in an emergency department (ED), is a recommended but under-utilized practice. To promote THN prescription, we developed a noninterruptive decision support intervention that combined a detailed OD documentation template with a reminder to use the template that is automatically inserted into a provider's note by decision rules. We studied the impact of the combined intervention on THN prescribing in a longitudinal observational study.

METHODS

ED encounters involving an OD were reviewed before and after implementation of the reminder embedded in the physicians' note to use an advanced OD documentation template for changes in: (1) use of the template and (2) prescription of THN. Chi square tests and interrupted time series analyses were used to assess the impact. Usability and satisfaction were measured using the System Usability Scale (SUS) and the Net Promoter Score.

RESULTS

In 736 OD cases defined by International Classification of Disease version 10 diagnosis codes (247 prereminder and 489 postreminder), the documentation template was used in 0.0% and 21.3%, respectively (P < .0001). The sensitivity and specificity of the reminder for OD cases were 95.9% and 99.8%, respectively. Use of the documentation template led to twice the rate of prescribing of THN (25.7% vs 50.0%, P < .001). Of 19 providers responding to the survey, 74% of SUS responses were in the good-to-excellent range and 53% of providers were Net Promoters.

CONCLUSIONS

A noninterruptive decision support intervention was associated with higher THN prescribing in a pre-post study across a multiinstitution health system.

Barriers and facilitators to implementing medications for opioid use disorder and naloxone distribution in Veterans Affairs emergency departments

OBJECTIVES

Safer opioid prescribing patterns, naloxone distribution, and medications for opioid use disorder (M-OUD) are an important part of decreasing opioid-related adverse events. Veterans are more likely to experience these adverse events compared to the general population. Despite treatment guidelines and ED-based opioid safety programs implemented throughout Veterans Affairs (VA) Medical Centers, many Veterans with OUD do not receive these harm reduction interventions. Prior research in other health care settings has identified barriers to M-OUD initiation and naloxone distribution; however, little is known about how this may be similar or different for health care professionals in VA ED and urgent care centers.

METHODS

We conducted qualitative interviews with VA health care professionals and staff using a semistructured interview guide. We analyzed the data addressing barriers and facilitators to M-OUD treatment in the ED and naloxone distribution using descriptive matrix analysis, followed by team consensus.

RESULTS

We interviewed 19 VA staff in various roles. Respondent concerns and considerations regarding the initiation of M-OUD in the ED included M-OUD initiation falling outside of ED's scope of providing acute treatment, lack of VA-approved M-OUD protocols and follow-up procedures, staffing concerns, and educational gaps. Respondents reported that naloxone was important but lacked clarity on who should prescribe it. Some respondents stated that an automated system to prescribe naloxone would be helpful, and others felt that it would not offer needed support and education to patients. Some respondents reported that naloxone would not address opioid misuse, which other respondents felt was a belief due to stigma around substance use and lack of education about treatment options.

CONCLUSIONS

Our VA-based research highlights similarities of barriers and facilitators, seen in other health care settings, when implementing opioid safety initiatives. Education and training, destigmatizing substance use disorder care, and leveraging technology are important facilitators to increasing access to lifesaving therapies for OUD treatment and harm reduction.

Models for Implementing Emergency Department-Initiated Buprenorphine With Referral for Ongoing Medication Treatment at Emergency Department Discharge in Diverse Academic Centers

There has been a substantial rise in the number of publications and training opportunities on the care and treatment of emergency department (ED) patients with opioid use disorder over the past several years. The American College of Emergency Physicians recently published recommendations for providing buprenorphine to patients with opioid use disorder, but barriers to implementing this clinical practice remain. We describe the models for implementing ED-initiated buprenorphine at 4 diverse urban, academic medical centers across the country as part of a federally funded effort termed "Project ED Health." These 4 sites successfully implemented unique ED-initiated buprenorphine programs as part of a comparison of implementation facilitation to traditional educational dissemination on the uptake of ED-initiated buprenorphine. Each site describes the elements central to the ED process, including screening, treatment initiation, referral, and follow-up, while harnessing organizational characteristics, including ED culture. Finally, we discuss common facilitators to program success, including information technology and electronic medical record integration, hospital-level support, strong connections with outpatient partners, and quality improvement processes.

Improving Uptake of Emergency Department-initiated Buprenorphine: Barriers and Solutions

Emergency departments (ED) are increasingly providing buprenorphine to persons with opioid use disorder. Buprenorphine programs in the ED have strong support from public health leaders and emergency medicine specialty societies and have proven to be clinically effective, cost effective, and feasible. Even so, few ED buprenorphine programs currently exist. Given this imbalance between evidence-based practice and current practice, proven behavior change approaches can be used to guide local efforts to expand ED buprenorphine capacity. In this paper, we use the theory of planned behavior to identify and address the 1) clinician factors, 2) institutional factors, and 3) external factors surrounding ED buprenorphine implementation. By doing so, we seek to provide actionable and pragmatic recommendations to increase ED buprenorphine availability across different practice settings.

User centered clinical decision support to implement initiation of buprenorphine for opioid use disorder in the emergency department: EMBED pragmatic cluster randomized controlled trial

OBJECTIVE

To determine the effect of a user centered clinical decision support tool versus usual care on rates of initiation of buprenorphine in the routine emergency care of individuals with opioid use disorder.

DESIGN

Pragmatic cluster randomized controlled trial (EMBED).

SETTING

18 emergency department clusters across five healthcare systems in five states representing the north east, south east, and western regions of the US, ranging from community hospitals to tertiary care centers, using either the Epic or Cerner electronic health record platform.

PARTICIPANTS

599 attending emergency physicians caring for 5047 adult patients presenting with opioid use disorder.

INTERVENTION

A user centered, physician facing clinical decision support system seamlessly integrated into user workflows in the electronic health record to support initiating buprenorphine in the emergency department by helping clinicians to diagnose opioid use disorder, assess the severity of withdrawal, motivate patients to accept treatment, and complete electronic health record tasks by automating clinical and after visit documentation, order entry, prescribing, and referral.

MAIN OUTCOME MEASURES

Rate of initiation of buprenorphine (administration or prescription of buprenorphine) in the emergency department among patients with opioid use disorder. Secondary implementation outcomes were measured with the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework.

RESULTS

1 413 693 visits to the emergency department (775 873 in the intervention arm and 637 820 in the usual care arm) from November 2019 to May 2021 were assessed for eligibility, resulting in 5047 patients with opioid use disorder (2787 intervention arm, 2260 usual care arm) under the care of 599 attending physicians (340 intervention arm, 259 usual care arm) for analysis. Buprenorphine was initiated in 347 (12.5%) patients in the intervention arm and in 271 (12.0%) patients in the usual care arm (adjusted generalized estimating equations odds ratio 1.22, 95% confidence interval 0.61 to 2.43, P=0.58). Buprenorphine was initiated at least once by 151 (44.4%) physicians in the intervention arm and by 88 (34.0%) in the usual care arm (1.83, 1.16 to 2.89, P=0.01).

CONCLUSIONS

User centered clinical decision support did not increase patient level rates of initiating buprenorphine in the emergency department. Although streamlining and automating electronic health record workflows can potentially increase adoption of complex, unfamiliar evidence based practices, more interventions are needed to look at other barriers to the treatment of addiction and increase the rate of initiating buprenorphine in the emergency department in patients with opioid use disorder.

"Just give them a choice": Patients' perspectives on starting medications for opioid use disorder in the ED

OBJECTIVES

Medications for opioid use disorder (MOUD) prescribed in the emergency department (ED) have the potential to save lives and help people start and maintain recovery. We sought to explore patient perspectives regarding the initiation of buprenorphine and methadone in the ED with the goal of improving interactions and fostering shared decision making (SDM) around these important treatment options.

METHODS

We conducted semistructured interviews with a purposeful sample of people with opioid use disorder (OUD) regarding ED visits and their experiences with MOUD. The interview guide was based on the Ottawa Decision Support Framework, a framework for examining decisional needs and tailoring decisional support, and the research team's experience with MOUD and SDM. Interviews were recorded, transcribed, and analyzed in an iterative process using both the Ottawa Framework and a social-ecological framework. Themes were identified and organized and implications for clinical care were noted and discussed.

RESULTS

Twenty-six participants were interviewed, seven in person in the ED and 19 via video conferencing software. The majority had tried both buprenorphine and methadone, and almost all had been in an ED for an issue related to opioid use. Participants reported social, pharmacological, and emotional factors that played into their decision making. Regarding buprenorphine, they noted advantages such as its efficacy and logistical ease and disadvantages such as the need to wait to start it (risk of precipitated withdrawal) and that one could not use other opioids while taking it. Additionally, participants felt that: (1) both buprenorphine and methadone should be offered; (2) because "one person's pro is another person's con," clinicians will need to understand the facets of the options; (3) clinicians will need to have these conversations without appearing judgmental; and (4) many patients may not be "ready" for MOUD, but it should still be offered.

CONCLUSIONS

Although participants were supportive of offering buprenorphine in the ED, many felt that methadone should also be offered. They felt that treatment should be tailored to an individual's needs and circumstances and clarified what factors might be important considerations for people with OUD.

Emergency Department-initiated Buprenorphine and Referral to Follow-up Addiction Care: A Program Description

INTRODUCTION

Emergency department (ED) initiated opioid use disorder (OUD) care is effective; however, real-world predictors of patient engagement are lacking.

OBJECTIVE

This program evaluation examined predictors of ED-based OUD treatment and subsequent engagement.

METHOD

Program evaluation in Boston, MA. Adult patients who met criteria for OUD during an ED visit in 2019 were included. Patients were included if a diagnosis of OUD or opioid-related overdose was associated with the ED visit or if they met previously validated criteria for OUD within the previous 12 months. We assessed predictors of ED-OUD treatment receipt and subsequent engagement, using Healthcare Effectiveness Data and Information Set definition of initial encounter within 14 days of discharge and either 2 subsequent encounters or a subsequent buprenorphine prescription within 34 days of the initial encounter. We used generalized estimating equations for panel data.

RESULTS

During 2019, 1946 patients met criteria for OUD. Referrals to Bridge Clinic were made for 207 (11%), buprenorphine initiated for 106 (5%), and home induction buprenorphine kits given to 56 (3%). Following ED discharge, 237 patients (12%) had a visit within 14 days, 122 (6%) had ≥2 additional visits, and 207 (11%) received a subsequent buprenorphine prescription. Young, White, male patients were most likely to receive ED-OUD care. Patients who received ED-OUD care were more likely to have subsequent treatment engagement (adjusted rate ratio: 2.30, 95% confidence intervals: 1.62-3.27). Referrals were made less often than predicted for Black (-49%) or Hispanic/Latinx (-25%) patients.

CONCLUSIONS

Initiating treatment for OUD in the ED was associated with increased engagement in outpatient addiction care.

Sustained Implementation of a Multicomponent Strategy to Increase Emergency Department-Initiated Interventions for Opioid Use Disorder

STUDY OBJECTIVE

There is strong evidence supporting emergency department (ED)-initiated buprenorphine for opioid use disorder, but less is known about how to implement this practice. Our aim was to describe implementation, maintenance, and provider adoption of a multicomponent strategy for opioid use disorder treatment in 3 urban, academic EDs.

METHODS

We conducted a retrospective analysis of electronic health record data for adult patients with opioid use disorder-related visits before (March 2017 to November 2018) and after (December 2018 to July 2020) implementation. We describe patient characteristics, clinical treatment, and process measures over time and conducted an interrupted time series analysis using a patient-level multivariable logistic regression model to assess the association of the interventions with buprenorphine use and other outcomes. Finally, we report provider-level variation in prescribing after implementation.

RESULTS

There were 2,665 opioid use disorder-related visits during the study period: 28% for overdose, 8% for withdrawal, and 64% for other conditions. Thirteen percent of patients received medications for opioid use disorder during or after their ED visit overall. Following intervention implementation, there were sustained increases in treatment and process measures, with a net increase in total buprenorphine of 20% in the postperiod (95% confidence interval 16% to 23%). In the adjusted patient-level model, there was an immediate increase in the probability of buprenorphine treatment of 24.5% (95% confidence interval 12.1% to 37.0%) with intervention implementation. Seventy percent of providers wrote at least 1 buprenorphine prescription, but provider-level buprenorphine prescribing ranged from 0% to 61% of opioid use disorder-related encounters.

CONCLUSION

A combination of strategies to increase ED-initiated opioid use disorder treatment was associated with sustained increases in treatment and process measures. However, adoption varied widely among providers, suggesting that additional strategies are needed for broader uptake.

Application of the RE-AIM Framework for the Pediatric Mild Traumatic Brain Injury Evaluation and Management Intervention: A Study Protocol for Program Evaluation

Background

Children who experience a mild Traumatic Brain Injury (mTBI) may encounter cognitive and behavioral changes that often negatively impact school performance. Communication linkages between the various healthcare systems and school systems are rarely well-coordinated, placing children with an mTBI at risk for prolonged recovery, adverse impact on learning, and mTBI re-exposure. The objective of this study is to rigorously appraise the pediatric Mild Traumatic Brain Injury Evaluation and Management (TEaM) Intervention that was designed to enhance diagnosis and management of pediatric mTBI through enhanced patient discharge instructions and communication linkages between school and primary care providers.

Methods

This is a combined randomized and 2 × 2 quasi-experimental study design with educational and technology interventions occurring at the clinician level with patient and school outcomes as key endpoints. The RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework will be utilized as a mix methods approach to appraise a multi-disciplinary, multi-setting intervention with the intent of improving outcomes for children who have experienced mTBI.

Discussion

Utilization of the RE-AIM framework complemented with qualitative inquiry is suitable for evaluating effectiveness of the TEaM Intervention with the aim of emphasizing priorities regarding pediatric mTBI. This program evaluation has the potential to support the knowledge needed to critically appraise the impact of mTBI recovery interventions across multiple settings, enabling uptake of the best-available evidence within clinical practice.

Redesign of Opioid Use Disorder Screening and Treatment in the ED

Traditionally, patients with opioid use disorder (OUD) seen in EDs have been medically cleared, discharged, and left to navigate a complex treatment system after discharge. Replacing this system of care requires reimagining the ED visit to promote best practices, including starting treatment with lifesaving medications for OUD in the ED. In this article, the authors present stakeholder-informed design of strategies for implementation of evidence-based ED OUD care at Penn Medicine. They used a participatory design approach to incorporate insights from diverse clinician groups in an iterative fashion to develop new processes of care that identified patients early to initiate OUD care pathways. Their design process led to the development of a nurse-driven protocol with OUD screening in ED triage coupled with automated prompts to both nurses and physicians or advanced practice providers to perform assessment and treatment of OUD and to deliver evidence-based treatment interventions.

Variation in emergency department visit rates for opioid use disorder: Implications for quality improvement initiatives

STUDY OBJECTIVE

Emergency departments (ED) are critical touchpoints for encounters among patients with opioid use disorder (OUD), but implementation of ED initiated treatment and harm reduction programs has lagged. We describe national patient, visit and hospital-level characteristics of ED OUD visits and characterize EDs with high rates of OUD visits in order to inform policies to optimize ED OUD care.

METHODS

We conducted a descriptive, cross-sectional study with the 2017 Nationwide Emergency Department Sample (NEDS) from the Healthcare Cost and Utilization Project, using diagnostic and mechanism of injury codes from ICD-10 to identify OUD related visits. NEDS weights were applied to generate national estimates. We evaluated ED visit and clinical characteristics of all OUD encounters. We categorized hospitals into quartiles by rate of visits for OUD per 1000 ED visits and described the visit, clinical, and hospital characteristics across the four quartiles.

RESULTS

In 2017, the weighted national estimate for OUD visits was 1,507,550. Overdoses accounted for 295,954. (19.6%) of visits. OUD visit rates were over 8× times higher among EDs in the highest quartile of OUD visit rate (22.9 per 1000 total ED visits) compared with EDs in the lowest quartile of OUD visit rate (2.7 per 1000 ED visits). Over three fifths (64.2%) of all OUD visits nationwide were seen by the hospitals in the highest quartile of OUD visit rate. These hospitals were predominantly in metropolitan areas (86.2%), over half were teaching hospitals (51.7%), and less than a quarter (23.3%) were Level 1 or Level 2 trauma centers.

CONCLUSION

Targeting initial efforts of OUD care programs to high OUD visit rate EDs could improve care for a large portion of OUD patients utilizing emergency care.

Clinician Perceptions About a Decision Support System to Identify and Manage Opioid Use Disorder

BACKGROUND

Addressing the opioid epidemic would benefit from primary care clinicians identifying and managing opioid use disorder (OUD) during routine clinical encounters, but current rates are low. Clinical decision support (CDS) systems are a promising way to facilitate such interactions, but will clinicians use them?

METHODS

We iteratively conducted semi-structured interviews with 8 purposively sampled primary care clinicians participating in a pilot OUD-CDS study to identify attitudes toward discussing OUD and preferences for support in doing so. Five of them had used a pilot version of the CDS for 6 months, while the others were in comparison clinics. Interviews were recorded, transcribed, and analyzed by a multi-disciplinary group of experienced researchers, using an editing organizing style where the analysts independently highlighted relevant text and then discussed to reach a consensus on themes.

RESULTS

We identified five themes: 1. Primary care is the right place to address OUD. 2. Both clinician-patient and clinician-clinician relationships affect how and whether clinicians address OUD in a particular patient encounter. 3. The main challenges are limited time and competing priorities for these complex patients. 4. Although a CDS for OUD could be very helpful, it must meet different needs for different clinicians and clinical situations and be simple to use. 5. For optimal benefit, the CDS needs to be complemented by supportive organizational policies and systems as well as local clinician encouragement.

CONCLUSIONS

With the right design and a supportive organization, these primary care clinicians believe a CDS could help them regularly identify and address OUD among their patients as long as it incorporates their concerns about relationships, competing priorities, patient complexity, and user simplicity.

Initiation of buprenorphine for opioid use disorder in the hospital setting: Practice models, challenges, and legal considerations

DISCLAIMER

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

PURPOSE

To provide health-system pharmacists with published examples of strategies utilized to offer buprenorphine to inpatients with opioid use disorder (OUD) along with information on challenges and legal considerations.

SUMMARY

Hospitals and emergency departments (EDs) are a constant source of healthcare for patients with OUD. As a result, hospital practitioners can screen, diagnose, begin treatment, and facilitate transfer of care to the outpatient setting. Offering sublingual buprenorphine in the hospital can bridge the gap before outpatient care is established. Multiple studies have shown that initiating treatment in the ED or during inpatient hospitalization results in 47% to 74% of patients utilizing medication-assisted treatment at day 30 of follow-up, statistically superior to the rates achieved with brief interventions or referral alone. Moreover, initiating buprenorphine treatment in the ED has been shown to decrease healthcare costs. Despite the benefits of offering buprenorphine in the inpatient setting, several challenges must be solved by hospital administration, such as achieving clinician readiness to prescribe buprenorphine, developing relationships with outpatient providers of buprenorphine, and creating an efficient workflow. Treatment of OUD with buprenorphine is heavily regulated on the federal level. Pharmacists can participate in the development of these programs and ensure compliance with applicable laws.

CONCLUSION

As health systems continue to care for patients with OUD, starting buprenorphine in the inpatient setting can improve the transition to outpatient treatment. Several institutions have developed programs with positive results. With an understanding of the typical barriers and relevant laws when initiating buprenorphine in the hospital setting, health-system pharmacists can assist in the development and operation of these initiatives.

Consensus Recommendations on the Treatment of Opioid Use Disorder in the Emergency Department

The treatment of opioid use disorder with buprenorphine and methadone reduces morbidity and mortality in patients with opioid use disorder. The initiation of buprenorphine in the emergency department (ED) has been associated with increased rates of outpatient treatment linkage and decreased drug use when compared to patients randomized to receive standard ED referral. As such, the ED has been increasingly recognized as a venue for the identification and initiation of treatment for opioid use disorder, but no formal American College of Emergency Physicians (ACEP) recommendations on the topic have previously been published. The ACEP convened a group of emergency physicians with expertise in clinical research, addiction, toxicology, and administration to review literature and develop consensus recommendations on the treatment of opioid use disorder in the ED. Based on literature review, clinical experience, and expert consensus, the group recommends that emergency physicians offer to initiate opioid use disorder treatment with buprenorphine in appropriate patients and provide direct linkage to ongoing treatment for patients with untreated opioid use disorder. These consensus recommendations include strategies for opioid use disorder treatment initiation and ED program implementation. They were approved by the ACEP board of directors in January 2021.

Emergency department-based efforts to offer medication treatment for opioid use disorder: What can we learn from current approaches?

BACKGROUND

The opioid epidemic remains a public health crisis and most people with opioid use disorder (OUD) do not receive effective treatment. The emergency department (ED) can be a critical entry point for treatment. EDs are developing and implementing ED-based efforts to address OUD to improve access to OUD treatment. This study's objective is to identify features of ED-based OUD treatment programs that relate to program implementation, effectiveness, and sustainability.

METHODS

We obtained data through literature review and semistructured interviews with ED physicians and leaders. The study analyzed these data to develop a framework of key components of ED-based efforts and highlight barriers and facilitators to implementation and program effectiveness.

RESULTS

We identify five key features of ED-based opioid treatment programs that vary across programs and may influence effectiveness and impact: patient identification methods; treatment approaches; program structure; relationship with community partners; and financing and sustainability. Successful implementation of ED-based OUD treatment includes having a champion, a reliable referral network, and systematic tracking and reporting of data for monitoring and feedback.

CONCLUSION

Going forward, attention to these features may help to improve effectiveness. As researchers conduct studies of ED-based care models, they should assess the impact of variation in key features to improve program effectiveness.

Improving transitions of care for patients initiated on buprenorphine for opioid use disorder from the emergency departments in King County, Washington

STUDY OBJECTIVE

Opioid use disorder (OUD) is on the rise nationwide with increasing emergency department (ED) visits and deaths secondary to overdose. Although previous research has shown that patients who are started on buprenorphine in the ED have increased engagement in addiction treatment, access to on-demand medications for OUD is still limited, in part because of the need for linkages to outpatient care. The objective of this study is to describe emergency and outpatient providers' perception of local barriers to transitions of care for ED-initiated buprenorphine patients.

METHODS

Purposive sampling was used to recruit key stakeholders, identified as physicians, addiction specialists, and hospital administrators, from 10 EDs and 11 outpatient clinics in King County, Washington. Twenty-one interviews were recorded and transcribed and then coded using an integrated deductive and inductive content analysis approach by 2 team members to verify accuracy of the analysis. Interview guides and coding were informed by the Consolidated Framework for Implementation Research (CFIR), which provides a structure of domains and constructs associated with effective implementation of evidence-based practice.

RESULTS

From the 21 interviews with emergency and outpatient providers, this study identified 4 barriers to transitions of care for ED-initiated buprenorphine patients: scope of practice, prescribing capacity, referral incoordination, and loss to follow-up.

CONCLUSION

Next steps for implementation of this intervention in a community setting include establishing a standard of care for treatment and referral for ED patients with OUD, increasing buprenorphine prescribing capacity, creating a central repository for streamlined referrals and follow-up, and supporting low-barrier scheduling and navigation services.

Increasing Naloxone Prescribing in the Emergency Department Through Education and Electronic Medical Record Work-Aids

BACKGROUND

Emergency department (ED) visits for opioid overdose continue to rise. Evidence-based harm reduction strategies for opioid use disorder (OUD), such as providing home naloxone, can save lives, but ED implementation remains challenging.

METHODS

The researchers aimed to increase prescribing of naloxone to ED patients with OUD and opioid overdose by employing a model for improvement methodology, a multidisciplinary team, and high-reliability interventions. Monthly naloxone prescribing rates among discharged ED patients with opioid overdose and OUD-related diagnoses were tracked over time. Interventions included focused ED staff education on OUD and naloxone, and creation of electronic medical record (EMR)-based work-aids, including a naloxone Best Practice Advisory (BPA) and order set. Autoregressive interrupted time series was used to model the impact of these interventions on naloxone prescribing rates. The impact of education on ED staff confidence and perceived barriers to prescribing naloxone was measured using a published survey instrument.

RESULTS

After adjusting for education events and temporal trends, ED naloxone BPA and order set implementation was associated with a significant immediate 21.1% increase in naloxone prescribing rates, which was sustained for one year. This corresponded to increased average monthly prescribing rates from 1.5% before any intervention to 28.7% afterward. ED staff education had no measurable impact on prescribing rates but was associated with increased nursing perceived importance and increased provider confidence in prescribing naloxone.

CONCLUSIONS

A significant increase in naloxone prescribing rates was achieved after implementation of high-reliability EMR work-aids and staff education. Similar interventions may be key to wider ED staff engagement in harm reduction for patients with OUD.

Misalignment of Stakeholder Incentives in the Opioid Crisis

The current opioid epidemic has killed more than 446,000 Americans over the past two decades. Despite the magnitude of the crisis, little is known to what degree the misalignment of incentives among stakeholders due to competing interests has contributed to the current situation. In this study, we explore evidence in the literature for the working hypothesis that misalignment rooted in the cost, quality, or access to care can be a significant contributor to the opioid epidemic. The review identified several problems that can contribute to incentive misalignment by compromising the triple aims (cost, quality, and access) in this epidemic. Some of these issues include the inefficacy of conventional payment mechanisms in providing incentives for providers, practice guidelines in pain management that are not easily implementable across different medical specialties, barriers in adopting multi-modal pain management strategies, low capacity of providers/treatments to address opioid/substance use disorders, the complexity of addressing the co-occurrence of chronic pain and opioid use disorders, and patients' non-adherence to opioid substitution treatments. In discussing these issues, we also shed light on factors that can facilitate the alignment of incentives among stakeholders to effectively address the current crisis.
