Barriers and facilitators to implementing treatment for opioid use disorder in community hospitals.

INTRODUCTION: Methadone and buprenorphine are effective treatment for opioid use disorder (OUD), yet they are vastly under-utilized across US hospitals. To inform a national trial assessing the effectiveness of implementation strategies to increase adoption of an inpatient hospital-based opioid treatment (HBOT) model (NCT04921787), we explored barriers and facilitators to expanding medication for opioid use disorder (MOUD) within community hospitals across the United States. METHODS: From November 2021 to March 2022, we used purposeful and snowball sampling to identify and interview participants involved in inpatient care of patients with OUD from twelve community hospitals. We conducted semi-structured interviews on providers' experiences and perspectives on current treatment approaches as well as potential influences on MOUD expansion in their hospitals. We used thematic analysis to identify key barriers and facilitators that could impact implementation of an HBOT model, and organized these findings based on the Consolidated Framework for Implementation Research (CFIR). RESULTS: From qualitative interviews with 57 participants (30 physicians, 7 pharmacists, 6 nurses, and 14 professionals involved in the care of patients with OUD), we identified key barriers and facilitators mapped to CFIR's internal and outer settings. The most salient inner setting domains included tension for change and relative priority, compatibility, available resources, organizational culture, access to knowledge and information, relational connections and communications, and information technology infrastructure. Outer setting domains included policies and laws, financing, and partnerships and connections. CONCLUSIONS: Identifying potential barriers and facilitators can inform hospital-specific strategies to support implementation of HBOT. Implementation strategies that address barriers such as staff availability, knowledge, and attitudes may support increased HBOT adoption. On a broader scale, national policy changes such as increased financing and public reporting of quality metrics would address other barriers we identified and may also encourage hospitals to adopt HBOT models.

Piloting a Hospital-Based Rapid Methadone Initiation Protocol for Fentanyl.

OBJECTIVES: Treating acute opioid withdrawal and offering medications for opioid use disorder (OUD) is critical. Hospitalization offers a unique opportunity to rapidly initiate methadone for OUD; however, little clinical guidance exists. This report describes our experience during the first 9 months following introduction of a hospital-based rapid methadone initiation protocol. METHODS: We conducted a retrospective chart review of hospitalized patients with OUD seen by our interprofessional addiction medicine consult service at an urban academic center between December 2022 and August 2023. We identified patients who initiated methadone using the rapid methadone initiation protocol, which includes dose recommendations (maximum 60 mg day 1, 70 mg day 2, 80 mg day 3, 100 mg days 4-7) and strict inclusion and exclusion criteria (end organ failure, arrhythmia, concurrent benzodiazepine or alcohol use, age >65). RESULTS: There were 171 patients that received methadone for OUD during the study period. Of those, 25 patients (15%) received rapid methadone initiation. The average total daily dose of methadone on days 1-7 was 53.0 mg, 69.2 mg, 75.4 mg, 79.5 mg, 87.1 mg, 92.2 mg, and 96.6 mg, respectively. There were no adverse events requiring holding a dose of scheduled methadone, naloxone administration, or transfer to higher level of care. CONCLUSIONS: A rapid methadone initiation protocol for OUD can be implemented in the inpatient setting. Patients up-titrated their methadone doses quicker than with traditional induction methods, and there were no serious adverse events. Appropriate patient selection may be important to avoid harms.

A Taxonomy of Hospital-Based Addiction Care Models: a Scoping Review and Key Informant Interviews.

BACKGROUND: There is pressing need to improve hospital-based addiction care. Various models for integrating substance use disorder care into hospital settings exist, but there is no framework for describing, selecting, or comparing models. We sought to fill that gap by constructing a taxonomy of hospital-based addiction care models based on scoping literature review and key informant interviews. METHODS: Methods included a scoping review of the literature on US hospital-based addiction care models and interventions for adults, published between January 2000 and July 2021. We conducted semi-structured interviews with 15 key informants experienced in leading, implementing, evaluating, andpracticing hospital-based addiction care to explore model characteristics, including their perceived strengths, limitations, and implementation considerations. We synthesized findings from the literature review and interviews to construct a taxonomy of model types. RESULTS: Searches identified 2,849 unique abstracts. Of these, we reviewed 280 full text articles, of which 76 were included in the final review. We added 8 references from reference lists and informant interviews, and 4 gray literature sources. We identified six distinct hospital-based addiction care models. Those classified as addiction consult models include (1) interprofessional addiction consult services, (2) psychiatry consult liaison services, and (3) individual consultant models. Those classified as practice-based models, wherein general hospital staff integrate addiction care into usual practice, include (4) hospital-based opioid treatment and (5) hospital-based alcohol treatment. The final type was (6) community-based in-reach, wherein community providers deliver care. Models vary in their target patient population, staffing, and core clinical and systems change activities. Limitations include that some models have overlapping characteristics and variable ways of delivering core components. DISCUSSION: A taxonomy provides hospital clinicians and administrators, researchers, and policy-makers with a framework to describe, compare, and select models for implementing hospital-based addiction care and measure outcomes.

Collaboration in a time of crisis: Adapting a telementoring ECHO for addiction leaders during COVID-19.

Substance use disorder (SUD) organizations are often siloed, with little integration across specialty addictions treatment, primary care and hospitals, harm reduction, policy, and advocacy. COVID-19 introduced a pressing need for collaboration and leadership, given a fast-changing, high-stakes environment; widespread anxiety; and lack of guidance. This research letter describes our approach to convening and supporting leaders across the US state of Oregon's SUD continuum during the pandemic. We rapidly developed and implemented a SUD COVID Response ECHO, adapting ECHO - a telementoring model - to convene leaders across 32 statewide agencies. Our experience allowed participants to lead their agencies to respond to real-time COVID-related needs, address existing barriers within SUD systems, and build relationships and community across statewide SUD leaders. This kind of collaboration - which helped bridge gaps among the diverse agencies, disciplines, and regions addressing SUDs in the state - was long overdue, and sows seeds for long-term advances in care for people with SUD.

Trust in Hospital Physicians Among Patients With Substance Use Disorder Referred to an Addiction Consult Service: A Mixed-methods Study.

BACKGROUND: Trust is essential in patient-physician relationships. Hospitalized patients with substance use disorders (SUDs) often experience stigma and trauma in the hospital, which can impede trust. Little research has explored the role of hospital-based addictions care in creating trusting relationships with patients with SUDs. This study describes how trust in physicians changed among hospitalized people with SUDs who were seen by an interprofessional addiction medicine service. METHODS: We analyzed data from hospitalized patients with SUD seen by an addiction consult service from 2015 to 2018. Participants completed surveys at baseline and 30 to 90 days after hospital discharge. Follow-up assessments included open-ended questions exploring participant experiences with hospitalization and the addiction consult service. We measured provider trust using the Wake Forest Trust scale. We modeled trust trajectories using discrete mixture modeling, and sampled qualitative interviews from those trust trajectories. RESULTS: Of 328 participants with SUD who had prior hospitalizations but had not previously been seen by an addiction consult service, 196 (59.8%) had both baseline and follow-up trust scores. We identified 3 groups of patients: Persistent-Low Trust, Increasing Trust, and Persistent-High Trust and 4 qualitative themes around in-hospital trust: humanizing care, demonstrating addiction expertise, reliability, and granting agency. CONCLUSIONS: Most participants retained or increased to high trust levels after hospitalization with an addiction consult service. Addiction consult services can create environments where healthcare providers build trust with, and humanize care for, hospitalized patients with SUD, and can also mitigate power struggles that hospitalized patients with SUD frequently experience.

Spreading Addictions Care Across Oregon's Rural and Community Hospitals: Mixed-Methods Evaluation of an Interprofessional Telementoring ECHO Program.

BACKGROUND: Despite evidence of effectiveness, most US hospitals do not deliver hospital-based addictions care. ECHO (Extension for Community Healthcare Outcomes) is a telementoring model for providers across diverse geographic areas. We developed and implemented a substance use disorder (SUD) in hospital care ECHO to support statewide dissemination of best practices in hospital-based addictions care. OBJECTIVES: Assess the feasibility, acceptability, and effects of ECHO and explore lessons learned and implications for the spread of hospital-based addictions care. DESIGN: Mixed-methods study with a pre-/post-intervention design. PARTICIPANTS: Interprofessional hospital providers and administrators across Oregon. INTERVENTION: A 10-12-week ECHO that included participant case presentations and brief didactics delivered by an interprofessional faculty, including peers with lived experience in recovery. APPROACH: To assess feasibility and acceptability, we collected enrollment, attendance, and participant feedback data. To evaluate ECHO effects, we used pre-/post-ECHO assessments and performed a thematic analysis of open-ended survey responses and participant focus groups. KEY RESULTS: We recruited 143 registrants to three cohorts between January and September 2019, drawing from 32 of Oregon's 62 hospitals and one southwest Washington hospital. Ninety-six (67.1%) attended at least half of ECHO sessions. Participants were highly satisfied with ECHO. After ECHO, participants were more prepared to treat SUD; however, prescribing did not change. Participants identified substantial gains in knowledge and skills, particularly regarding the use of medications for opioid use disorder; patient-centered communication with people who use drugs; and understanding harm reduction as a valid treatment approach. ECHO built a community of practice and reduced provider isolation. Participants recognized the need for supportive hospital leadership, policies, and SUD resources to fully implement and adopt hospital-based SUD care. CONCLUSIONS: A statewide, interprofessional SUD hospital care ECHO was feasible and acceptable. Findings may be useful to health systems, states, and regions looking to expand hospital-based addictions care.

Predictors of Opioid and Alcohol Pharmacotherapy Initiation at Hospital Discharge Among Patients Seen by an Inpatient Addiction Consult Service.

BACKGROUND: Medications for opioid use disorder (MOUD) and alcohol use disorder (MAUD) are effective and under-prescribed. Hospital-based addiction consult services can engage out-of-treatment adults in addictions care. Understanding which patients are most likely to initiate MOUD and MAUD can inform interventions and deepen understanding of hospitals' role in addressing substance use disorders (SUD). OBJECTIVE: Determine patient- and consult-service level characteristics associated with MOUD/MAUD initiation during hospitalization. METHODS: We analyzed data from a study of the Improving Addiction Care Team (IMPACT), an interprofessional hospital-based addiction consult service at an academic medical center. Researchers collected patient surveys and clinical data from September 2015 to May 2018. We used logistic regression to identify characteristics associated with medication initiation among participants with OUD, AUD, or both. Candidate variables included patient demographics, social determinants, and treatment-related factors. RESULTS: Three hundred thirty-nine participants had moderate to severe OUD, AUD, or both and were not engaged in MOUD/MAUD care at admission. Past methadone maintenance treatment (aOR 2.07, 95%CI (1.17, 3.66)), homelessness (aOR 2.63, 95%CI (1.52, 4.53)), and partner substance use (aOR 2.05, 95%CI (1.12, 3.76) were associated with MOUD/MAUD initiation. Concurrent methamphetamine use disorder (aOR 0.32, 95%CI (0.18, 0.56)) was negatively associated with MOUD/MAUD initiation. CONCLUSIONS: The association of MOUD/MAUD initiation with homelessness and partner substance use suggests that hospitalization may be an opportunity to reach highly-vulnerable people, further underscoring the need to provide hospital-based addictions care as a health-system strategy. Methamphetamine's negative association with MOUD/MAUD warrants further study.

"If It Wasn't for Him, I Wouldn't Have Talked to Them": Qualitative Study of Addiction Peer Mentorship in the Hospital.

BACKGROUND: Hospitalizations related to substance use disorders (SUD) are skyrocketing. Hospital providers commonly feel unprepared to care for patients with SUD and patients with SUD commonly feel discriminated against by hospital staff. This tension can lead to provider burnout and poor patient outcomes. Research in ambulatory settings suggests that peer mentors (PMs) can improve substance use outcomes and patient experience. However, no study has examined the role of peer mentorship for patients with SUD in hospitals. OBJECTIVE: Understand how peer mentorship affects care for hospitalized patients with SUD, and how working in a hospital affects PMs' sense of professional identity. DESIGN: Qualitative study utilizing participant observation, individual interviews, and focus groups related to the PM component of the Improving Addiction Care Team (IMPACT), a hospital-based interprofessional addiction medicine consult service. PARTICIPANTS: IMPACT providers, patients seen by IMPACT, PMs, and a PM supervisor. APPROACH: Qualitative thematic analysis. KEY RESULTS: PMs occupy a unique space in the hospital and are able to form meaningful relationships with hospitalized patients based on trust and shared lived experiences. PMs facilitate patient care by contextualizing patient experiences to teams and providers. Reciprocally, PMs "translate" provider recommendations to patients in ways that patients can hear. Respondents described PMs as "cultural brokers" who have the potential to transfer trust that they have earned with patients to providers and systems who may otherwise be viewed as untrustworthy. While PMs felt their role led to professional and personal development, the intensity of the role in the hospital setting also put them at risk for emotional drain and stress. CONCLUSIONS: While integrating PMs into hospital care presents substantial challenges, PMs may act as a "secret weapon" to engage often marginalized hospitalized patients with SUD and improve patient and provider experience.
