Transitions in care between hospital and community settings for individuals with a substance use disorder: A systematic review

Hospital Provider's Perspectives on MOUD Initiation and Continuation After Inpatient Discharge

BACKGROUND

Individuals with opioid use disorder have high rates of hospital admissions, which represent a critical opportunity to engage patients and initiate medications for opioid use disorder (MOUD). However, few patients receive MOUD and, even if MOUD is initiated in the hospital, patients may encounter barriers to continuing MOUD in the community.

OBJECTIVE

Describe hospital providers' experiences and perspectives to inform initiatives and policies that support hospital-based MOUD initiation and continuation in community treatment programs.

DESIGN

As part of a broader implementation study focused on inpatient MOUD (NCT#04921787), we conducted semi-structured interviews with hospital providers.

PARTICIPANTS

Fifty-seven hospital providers from 12 community hospitals.

APPROACH

Thematic analysis examined an emergent topic on challenges transitioning patients to outpatient MOUD treatment and related impacts on MOUD initiation by inpatient providers.

KEY RESULTS

Participants described structural barriers to transitioning hospitalized patients to continuing outpatient MOUD including (a) limited outpatient buprenorphine prescriber availability, (b) the siloed nature of addiction treatment, and (c) long wait times. As a result of observing these structural barriers, participants experienced a sense of futility that deterred them from initiating MOUD. Participants proposed strategies that could better support these patient transitions, including developing partnerships between hospitals and outpatient addiction treatment and supporting in-reach services from community providers.

CONCLUSIONS

We identified concerns about inadequate and inaccessible community-based care and transition pathways that discouraged hospital providers from prescribing MOUD. As hospital-based opioid treatment models continue to expand, programmatic and policy strategies to support inpatient transitions to outpatient addiction treatment are needed.

Long-term effectiveness of SBIRT by outreach visits on subsequent alcohol treatment utilization among inpatients from general hospital: a 36-months follow-up

AIM

To investigate the long-term effect of Screening, Brief Intervention, and Referral to Treatment (SBIRT) on alcohol treatment utilization among general hospital inpatients.

METHODS

This 36-month follow-up of a randomized controlled trial included general hospital inpatients who were screened using the Alcohol Use Disorder Identification Test (AUDIT). Patients with an AUDIT score of 8+ were included. Patients were randomized to either SBIRT (Relay) or treatment as-usual (TAU). Outcome was attendance at a specialized outpatient treatment institution or prescription of pharmacological alcohol treatment in general practice. Using the Danish Civil Registration System, patients were followed in the Danish National Patient Registry, Danish National Alcohol Treatment Register, and the Danish National Prescription Registry. Data was collected up to 36 months after discharge.

RESULTS

The study population consisted of 258 patients in the Relay group and 303 patients in the TAU group. In the Relay group, 36 (14.0%) patients received treatment versus 23 (7.6%) in the TAU group. Patients in the Relay group had higher odds for receiving treatment compared to the TAU group (OR: 1.97, 95% CI: 1.1-3.4, p = 0.01). Significantly more patients in the Relay group scored 16+ on the AUDIT and had already tried to change their alcohol consumption (both p < 0.01). Adjusted for potential confounders, the effect of the Relay intervention was reduced (OR: 1.37, 95%CI: 0.7-2.5, p = 0.31).

CONCLUSIONS

This study did not find evidence that SBIRT is better than TAU at sustaining significant long-term alcohol treatment utilization after discharge among inpatients from general hospital.

Characterising individuals with a substance use disorder accessing hospital-based addiction care: Preliminary description of the outcomes for patients accessing addiction care prospective cohort study

INTRODUCTION

Individuals with a substance use disorder (SUD) often face barriers to accessing health care, resulting in unmet needs and delayed care. Hospital-based services have the potential to engage individuals with a SUD in ongoing treatment, but there is limited literature characterising this population.

METHODS

The Outcomes for Patients Accessing Addiction Care study was a prospective hospital-based cohort study conducted at St. Paul's Hospital in Vancouver, Canada. Participants were recruited from January 2018 to March 2020. Data were collected through an interviewer-administered questionnaire, including socio-demographic information, substance use history and mental health screening.

RESULTS

The cohort included 536 participants, with 31% aged 30-39 years, 63% identifying as White and 74% reporting male sex at birth. Nearly half of the participants were either homeless or living in single room occupancy. Use of substances more than once per week was reported for tobacco/nicotine (86%), marijuana (43%), non-medical use of prescription drugs (29%), illicit stimulants (52%) and illicit opioids (61%).

DISCUSSION AND CONCLUSION

This preliminary report provides a description of a hospital-based cohort of individuals with a SUD accessing addiction care. The findings highlight demographic characteristics, mental health issues, substance use patterns and barriers to accessing services. Understanding these factors can inform the development of patient-centred interventions and improve engagement and retention in addiction care. Further research is needed to explore interventions and program effectiveness in this population.

Expert Panel Consensus on the Effectiveness and Implementation of Models to Support Posthospitalization Care Transitions for People With Substance Use Disorders

OBJECTIVES

Hospitals are increasingly offering treatment for substance use disorders (SUDs) during medical admissions. However, there is a lack of consensus on the best approach to facilitating a successful transition to long-term medical and SUD care after hospitalization. We aimed to establish a hierarchy of existing SUD care transition models in 2 categories-effectiveness and implementation-using an expert consensus approach.

METHODS

We conducted a modified online Delphi study that convened 25 interdisciplinary clinicians with experience facilitating posthospitalization care transitions for patients with SUD. Panelists rated 10 prespecified posthospitalization care transition models according to 6 criteria concerning each model's anticipated effectiveness (eg, linkage to care, treatment retention) and implementation (eg, feasibility, acceptability). Ratings were made on a 9-point bidirectional scale. Group consensus was determined using the interpercentile range adjusted for symmetry.

RESULTS

After 3 rounds of the Delphi process (96% retention across all 3 rounds), consensus was reached on all 60 rating criteria. Interdisciplinary addiction consult teams (ACTs) and in-reach from partnering outpatient clinics were rated highest for effectiveness. Interdisciplinary ACTs and bridge clinics were rated highest for implementation. Screening, brief intervention, and referral to treatment; protocol implementation; and postdischarge outreach received the lowest ratings overall. Feasibility of implementation was perceived as the largest challenge for all highly rated models.

CONCLUSIONS

An expert consensus approach including diverse clinician stakeholders found that interdisciplinary ACT, in-reach from partnering outpatient clinics, and bridge clinics had the greatest potential to enhance posthospitalization care transitions for patients with SUD when considering both perceived effectiveness and implementation.

Outcomes and Cost-Effectiveness of an EHR-Embedded AI Screener for Identifying Hospitalized Adults at Risk for Opioid Use Disorder

Hospitalized adults with opioid use disorder (OUD) are at high risk for adverse events and rehospitalizations. This pre-post quasi-experimental study evaluated whether an AI-driven OUD screener embedded in the electronic health record (EHR) was non-inferior to usual care in identifying patients for Addiction Medicine consults, aiming to provide a similarly effective but more scalable alternative to human-led ad hoc consultations. The AI screener analyzed EHR notes in real-time with a convolutional neural network to identify patients at risk and recommend consultation. The primary outcome was the proportion of patients receiving consults, comparing a 16-month pre-intervention period to an 8-month post-intervention period with the AI screener. Consults did not change between periods (1.35% vs 1.51%, p < 0.001 for non-inferiority). The AI screener was associated with a reduction in 30-day readmissions (OR: 0.53, 95% CI: 0.30-0.91, p = 0.02) with an incremental cost of $6,801 per readmission avoided, demonstrating its potential as a scalable, cost-effective solution for OUD care.

Barriers and Facilitators to Establishing Partnerships for Substance Use Disorder Care Transitions Between Safety-Net Hospitals and Community-Based Organizations

BACKGROUND

The effectiveness of hospital-based transitional opioid programs (TOPs), which aim to connect patients with substance use disorders (SUD) to ongoing treatment in the community following initiation of medication for opioid use disorder (MOUD) treatment in the hospital, hinges on successful patient transitions. These transitions are enabled by strong partnerships between hospitals and community-based organizations (CBOs). However, no prior study has specifically examined barriers and facilitators to establishing SUD care transition partnerships between hospitals and CBOs.

OBJECTIVE

To identify barriers and facilitators to developing partnerships between hospitals and CBOs to facilitate care transitions for patients with SUDs.

DESIGN

Qualitative study using semi structured interviews conducted between November 2022-August 2023.

PARTICIPANTS

Staff and providers from hospitals affiliated with four safety-net health systems (n=21), and leaders and staff from the CBOs with which they had established partnerships (n=5).

APPROACH

Interview questions focused on barriers and facilitators to implementing TOPs, developing partnerships with CBOs, and successfully transitioning SUD patients from hospital settings to CBOs.

KEY RESULTS

We identified four key barriers to establishing transition partnerships: policy and philosophical differences between organizations, ineffective communication, limited trust, and a lack of connectivity between data systems. We also identified three facilitators to partnership development: strategies focused on building partnership quality, strategic staffing, and organizing partnership processes.

CONCLUSIONS

Our findings demonstrate that while multiple barriers to developing hospital-CBO partnerships exist, stakeholders can adopt implementation strategies that mitigate these challenges such as using mediators, cross-hiring, and focusing on mutually beneficial services, even within resource-limited safety-net settings. Policymakers and health system leaders who wish to optimize TOPs in their facilities should focus on adopting implementation strategies to support transition partnerships such as inadequate data collection and sharing systems.

Hospitalists' Attitudes and Experiences With Posthospitalization Care Transitions for Patients With Substance Use Disorders: A Cross-sectional Analysis

BACKGROUND

Medical hospitalizations are relatively common among individuals who have substance use disorders (SUDs) and represent opportunities for patient engagement and treatment. Posthospitalization transitions of care are an important element of providing full-spectrum inpatient SUD care; however, little is known about clinicians' experiences with postdischarge care transitions.

METHODS

We conducted a cross-sectional study surveying hospital-based medical clinicians (ie, "hospitalists") across 2 large health systems in the state of Utah to assess current practices, barriers, facilitators, and perceptions toward posthospitalization care transitions for patients with SUDs. We used Wilcoxon signed-rank tests to identify the most impactful barriers and facilitators among all respondents. We used logistic regression models to explore the influence of hospitalists' attitudes toward providing SUD care on perceived barriers and facilitators.

RESULTS

The survey was distributed to 429 individuals across 15 hospitals. Eighty-two hospitalists responded to the survey (response rate, 21.4%). Most respondents frequently cared for hospitalized patients with SUDs (n = 63, 77%) and prescribed medications for SUDs (n = 44, 56%). Four respondents (5%) felt that patients received adequate support during care transitions. Lack of social support ( P < 0.001) and social factors such as lack of transportation ( P < 0.001) were perceived as the largest barriers to successful care transitions. Conversely, a partnering outpatient clinic/clinician ( P < 0.001) and outpatient-based care coordination ( P < 0.001) were perceived as the strongest facilitators. Respondents' attitudes toward people with SUDs had a modest effect on perceived barriers and facilitators.

CONCLUSIONS

Hospitalists perceived increased outpatient SUD treatment infrastructure and transitional care supports as most important in facilitating posthospitalization care transitions for patients with SUDs.

Using the Delphi Process to Prioritize an Agenda for Care Transition Research for Patients With Substance Use Disorders

Medical hospitalizations are increasingly recognized as important opportunities to engage individuals with substance use disorders (SUD) and offer treatment. While a growing number of hospitals have instituted interventions to support the provision of SUD care during medical admissions, post-hospitalization transitions of care remain a challenge for patients and clinicians and an understudied area of SUD care. Evidence is lacking on the most effective and feasible models of care to improve post-hospitalization care transitions for people with SUD. In the absence of strong empirical evidence to guide practice and policy, consensus-based research methods such as the Delphi process can play an important role in efficiently prioritizing existing models of care for future study and implementation. We conducted a Delphi study that convened a group of 25 national interdisciplinary experts with direct clinical experience facilitating post-hospitalization care transitions for people with SUD. Our panelists rated 10 existing care transition models according to anticipated effectiveness and facility of implementation based on the GRADE Evidence to Decision framework. Qualitative data on each care model were also gathered through comments and an online moderated discussion board. Our results help establish a hierarchy of SUD care transition models to inform future study and program development.

Rural-urban disparities in the availability of hospital-based screening, medications for opioid use disorder, and addiction consult services

INTRODUCTION

Hospitals are an ideal setting to stage opioid-related interventions with patients who are hospitalized due to overdose or other substance use-related complications. Transitional opioid programs-which initiate care and provide linkages upon discharge, such as screening, initiation of medications for opioid use disorder, and addiction consult services-have become the gold standard, but implementation has been uneven. The purpose of this study was to assess disparities in the availability of hospital-based transitional opioid programs, across rural and urban hospital settings in the United States.

METHODS

Using hospital administrative data paired with county-level demographic data, we conducted bivariate and regression analyses to assess rural-urban differences in the availability of transitional opioid services including screening, addiction consult services, and MOUD in U.S general medical centers, controlling for hospital- and community-level factors. Our sample included 2846 general medical hospitals that completed the 2021 American Hospital Association (AHA) Annual Survey of Hospitals. Our primary outcomes were five self-reported measures: whether the hospital provided screening in the ED; provided screening in the inpatient setting; whether the hospital provided addiction consult services in the ED; provided addiction consult services in the inpatient setting; and whether the hospital provided medications for opioid use disorder.

RESULTS

Rural hospitals did not have lower odds of screening for OUD or other SUDs than urban hospitals, but both micropolitan rural counties and noncore rural counties had significantly lower odds of having addiction consult services in either the ED (OR: 0.74, 95 % CI: 0.58, 0.95; OR: 0.68, 95 % CI: 0.50, 0.91) or inpatient setting (OR: 0.76, 95 % CI: 0.59, 0.97; OR: 0.68, 95 % CI: 0.50, 0.93), respectively, or of offering MOUD (OR: 0.69, 95 % CI: 0.52, 0.90; OR: 0.52, 95 % CI: 0.37, 0.74).

CONCLUSIONS

Our study suggests that evidence-based interventions, such as medications for opioid use disorder and addiction consult services, are less often available in rural hospitals, which may contribute to rural-urban disparities in health outcomes secondary to OUD. A priority for population health improvement should be developing implementation strategies to support rural hospital adoption of transitional opioid programs.

Post-hospitalization Care Transition Strategies for Patients with Substance Use Disorders: A Narrative Review and Taxonomy

Hospitalizations represent important opportunities to engage individuals with substance use disorders (SUD) in treatment. For those who engage with SUD treatment in the hospital setting, tailored supports during post-discharge transitions to longitudinal care settings may improve care linkages, retention, and treatment outcomes. We updated a recent systematic review search on post-hospitalization SUD care transitions through a structured review of published literature from January 2020 through June 2023. We then added novel sources including a gray literature search and key informant interviews to develop a taxonomy of post-hospitalization care transition models for patients with SUD. Our updated literature search generated 956 abstracts not included in the original systematic review. We selected and reviewed 89 full-text articles, which yielded six new references added to 26 relevant articles from the original review. Our search of five gray literature sources yielded four additional references. Using a thematic analysis approach, we extracted themes from semi-structured interviews with 10 key informants. From these results, we constructed a taxonomy consisting of 10 unique SUD care transition models in three overarching domains (inpatient-focused, transitional, outpatient-focused). These models include (1) training and protocol implementation; (2) screening, brief intervention, and referral to treatment; (3) hospital-based interdisciplinary consult team; (4) continuity-enhanced interdisciplinary consult team; (5) peer navigation; (6) transitional care management; (7) outpatient in-reach; (8) post-discharge outreach; (9) incentivizing follow-up; and (10) bridge clinic. For each model, we describe design, scope, approach, and implementation strategies. Our taxonomy highlights emerging models of post-hospitalization care transitions for patients with SUD. An established taxonomy provides a framework for future research, implementation efforts, and policy in this understudied, but critically important, aspect of SUD care.

Strategies to improve delivery of equitable and evidence-informed care for pregnant and birthing people with a substance use disorder in acute care settings: A scoping review protocol

This protocol outlines a proposed scoping review to characterize evidence on implementation and quality improvement (QI) strategies that aim to improve equitable, evidence-informed care delivery for pregnant and birthing people with substance use disorder (SUD) in acute care. Untreated SUD during pregnancy is associated with an increased risk of overdose and severe maternal morbidity. Acute care settings are one important place to deliver equitable, evidence-informed clinical care. While clinical practice guidelines for substance use treatment and care of pregnant and birthing people with SUD exist, there are gaps in implementation. Our population of interest is pregnant and birthing people with SUD in an acute care setting. We will include US-based studies that describe or evaluate implementation or QI strategies, including experimental, observational, and descriptive studies published from 2016 to 2023. The proposed scoping review will be conducted in accordance with JBI methodology for scoping reviews and registered at OSF (registration number: BC4VZ). We will search MEDLINE (PubMed), CINAHL Complete (EBSCO), Scopus (Elsevier), and APA PsychInfo (Ovid) for published studies. Conference proceedings and Perinatal Quality Collaborative websites will be searched for grey literature. Two reviewers will independently screen then extract studies that meet inclusion criteria using a data extraction tool. The completion of this scoping review will help illuminate strengths and gaps in research and practice that aim to inform substance use treatment and care in acute care settings for pregnant and birthing people with SUD.

Emergency Department Peer Support Program and Patient Outcomes After Opioid Overdose

Importance

Patients treated in emergency departments (EDs) for opioid overdose often need drug treatment yet are rarely linked to services after discharge. Emergency department-based peer support is a promising approach for promoting treatment linkage, but evidence of its effectiveness is lacking.

Objective

To examine the association of the Opioid Overdose Recovery Program (OORP), an ED peer recovery support service, with postdischarge addiction treatment initiation, repeat overdose, and acute care utilization.

Design, Setting, and Participants

This intention-to-treat retrospective cohort study used 2014 to 2020 New Jersey Medicaid data for Medicaid enrollees aged 18 to 64 years who were treated for nonfatal opioid overdose from January 2015 to June 2020 at 70 New Jersey acute care hospitals. Data were analyzed from August 2022 to November 2023.

Exposure

Hospital OORP implementation.

Main Outcomes and Measures

The primary outcome was medication for opioid use disorder (MOUD) initiation within 60 days of discharge. Secondary outcomes included psychosocial treatment initiation, medically treated drug overdoses, and all-cause acute care visits after discharge. An event study design was used to compare 180-day outcomes between patients treated in OORP hospitals and those treated in non-OORP hospitals. Analyses adjusted for patient demographics, comorbidities, and prior service use and for community-level sociodemographics and drug treatment access.

Results

A total of 12 046 individuals were included in the study (62.0% male). Preimplementation outcome trends were similar for patients treated in OORP and non-OORP hospitals. Implementation of the OORP was associated with an increase of 0.034 (95% CI, 0.004-0.064) in the probability of 60-day MOUD initiation in the half-year after implementation, representing a 45% increase above the preimplementation mean probability of 0.075 (95% CI, 0.066-0.084). Program implementation was associated with fewer repeat medically treated overdoses 4 half-years (-0.086; 95% CI, -0.154 to -0.018) and 5 half-years (-0.106; 95% CI, -0.184 to -0.028) after implementation. Results differed slightly depending on the reference period used, and hospital-specific models showed substantial heterogeneity in program outcomes across facilities.

Conclusions and Relevance

In this cohort study of patients treated for opioid overdose, OORP implementation was associated with an increase in MOUD initiation and a decrease in repeat medically treated overdoses. The large variation in outcomes across hospitals suggests that treatment effects were heterogeneous and may depend on factors such as implementation success, program embeddedness, and availability of other hospital- and community-based OUD services.

Initiatives to Support the Transition of Patients With Substance Use Disorders From Acute Care to Community-based Services Among a National Sample of Nonprofit Hospitals

BACKGROUND

Hospitals are a key touchpoint to reach patients with substance use disorders (SUDs) and link them with ongoing community-based services. Although there are many acute care interventions to initiate SUD treatment in hospital settings, less is known about what services are offered to transition patients to ongoing care after discharge. In this study, we explore what SUD care transition strategies are offered across nonprofit US hospitals.

METHODS

We analyzed administrative documents from a national sample of US hospitals that indicated SUD as a top 5 significant community need in their Community Health Needs Assessment reports (2019-2021). Data were coded and categorized based on the nature of described services. We used data on hospitals and characteristics of surrounding counties to identify factors associated with hospitals' endorsement of transition interventions for SUD.

RESULTS

Of 613 included hospitals, 313 prioritized SUD as a significant community need. Fifty-three of these hospitals (17%) offered acute care interventions to support patients' transition to community-based SUD services. Most (68%) of the 53 hospitals described transition strategies without further detail, 23% described scheduling appointments before discharge, and 11% described discussing treatment options before discharge. No hospital characteristics were associated with offering transition interventions, but such hospitals were more likely to be in the Northeast, in counties with higher median income, and states that expanded Medicaid.

CONCLUSIONS

Despite high need, most US hospitals are not offering interventions to link patients with SUD from acute to community care. Efforts to increase acute care interventions for SUD should identify and implement best practices to support care continuity.

Pathways to professional mental care in the Swiss young adult community: a case-control study

Treatment success for mental health (MH) problems depends, among others, on the timeliness of help-seeking. Therefore, we studied the effect of symptoms and reasons for help-seeking on the point-of-contact and the most intensive professional treatment in a community sample. Participants were recruited as part of the 'Bern Epidemiological At-Risk' (BEAR) study on 16-40-year-old community persons of the Swiss canton Bern. Of the 2,683 participants, 615 (22.9%) reported at least one instance of help-seeking for MH problems and were selected for the presented analyses. Help-seeking behavior was assessed by a modified version of the 'WHO pathway-to-care questionnaire', from which the outcome 'most intensive MH professional contact' was generated. The effect of symptoms and reasons for help-seeking were analyzed in separate models using path analyses. Most help-seeking persons sought MH professional help (n = 405; 65.9%) with a high number of medical pre-contacts (n = 233; 37.9%). The 'most intensive MH professional contact' was provided after an average of 1.47 contacts. Both models showed negative associations between non-MH professional pre-contacts and the most intensive, likely most adequate MH treatment. In the symptom model, 'substance misuse' and 'central-vegetative problems' increased the general likelihood of MH professional contact. Our findings highlight the importance of the first point-of-contact in pathways to adequate MH care and, when seeking help from non-MH professional, of quick referrals to MH professionals. Awareness campaigns or training of health professionals, such as general practitioners, may support timely contact with MH professionals to improve diagnosis, prognosis, and outcome.

Emergency Department Bridge Model and Health Services Use Among Patients With Opioid Use Disorder

STUDY OBJECTIVES

Little is known about the effectiveness of bridge clinics as transitional care programs for people with opioid use disorder in emergency departments (EDs). We assessed the effect of bridge clinic referral on health services use among patients with opioid use disorder identified in the ED.

METHODS

We used data for individuals aged 18 years and over with active opioid use disorder and no history of medication for opioid use disorder who were administered medication for opioid use disorder while in the ED between January 2013 and August 2022. Bridge clinic referrals started in January 2021. Eligible patients after this date comprised the intervention group. The usual care group included eligible patients before bridge clinic implementation, who were a 1:1 propensity score matched to intervention patients. We estimated risk differences and 95% confidence limits for linkage to long-term care, ED use, and inpatient admission within 120 days of the index ED visit.

RESULTS

Our study population comprised 928 observations after matching. Patients referred to the bridge clinic had a higher risk of linkage to long-term care (risk differences=25%; 95% confidence limits: 20%, 30%), higher risk of ED use (risk differences=7.5%, 95% confidence limits: 1.6%, 13%), and lower risk of inpatient admission (risk differences= -1.9%, 95% confidence limits: -5.9%, 2.1%). Inpatient admission increased among patients with serious mental illness but decreased among patients without serious mental illness.

CONCLUSION

Our overall results suggest that bridge clinic referral increases linkage to long-term care. Nevertheless, qualitatively different effects on inpatient admission between patients with and without serious mental illness warrant consideration of unmet needs among patients with serious mental illness.

Strategies to support substance use disorder care transitions from acute-care to community-based settings: a scoping review and typology

BACKGROUND

Acute-care interventions that identify patients with substance use disorders (SUDs), initiate treatment, and link patients to community-based services, have proliferated in recent years. Yet, much is unknown about the specific strategies being used to support continuity of care from emergency department (ED) or inpatient hospital settings to community-based SUD treatment. In this scoping review, we synthesize the existing literature on patient transition interventions, and form an initial typology of reported strategies.

METHODS

We searched Pubmed, Embase, CINAHL and PsychINFO for peer-reviewed articles published between 2000 and 2021 that studied interventions linking patients with SUD from ED or inpatient hospital settings to community-based SUD services. Eligible articles measured at least one post-discharge treatment outcome and included a description of the strategy used to promote linkage to community care. Detailed information was extracted on the components of the transition strategies and a thematic coding process was used to categorize strategies into a typology based on shared characteristics. Facilitators and barriers to transitions of care were synthesized using the Consolidated Framework for Implementation Research.

RESULTS

Forty-five articles met inclusion criteria. 62% included ED interventions and 44% inpatient interventions. The majority focused on patients with opioid (71%) or alcohol (31%) use disorder. The transition strategies reported across studies were heterogeneous and often not well described. An initial typology of ten transition strategies, including five pre- and five post-discharge transition strategies is proposed. The most common strategy was scheduling an appointment with a community-based treatment provider prior to discharge. A range of facilitators and barriers were described, which can inform efforts to improve hospital-to-community transitions of care.

CONCLUSIONS

Strategies to support transitions from acute-care to community-based SUD services, although critical for ensuring continuity of care, vary greatly across interventions and are inconsistently measured and described. More research is needed to classify SUD care transition strategies, understand their components, and explore which lead to the best patient outcomes.
