Facilitators and barriers in implementing buprenorphine in the Veterans Health Administration

"I think we're getting better but we're still not there": Provider-based stigma and perceived barriers to care for people who use opioids (PWUO)

BACKGROUND

Despite significant efforts to improve access to medications for opioid use disorder (MOUD), uptake remains low relative to the scope of the problem in the United States. A growing body of quantitative and qualitative research has documented consistent barriers to MOUD treatment access and retention, at the level of individuals, institutions, and society at large. Stigma - surrounding both people who use opioids (PWUO) and treatment using MOUD - is among the most-cited barriers by patients and providers alike, yet few studies have examined provider-based stigma specifically, or considered its interaction with other impediments to OUD care.

METHODS

This paper employs a qualitative approach to the analysis of provider-based stigma among professionals involved in the treatment or supervision of individuals with OUD. We conducted and analyzed interviews with 19 professionals as part of a larger mixed methods study on stigma among substance use treatment providers and court personnel in Pennsylvania. Beyond capturing providers' perceptions of PWUO and MOUD, the authors asked participants to describe barriers to recovery, and the effective delivery of care within this population.

RESULTS

Interviewees enumerated multiple entrenched barriers that sometimes operated at different levels, such as criminal-legal involvement, which weakened PWUO's social networks and employment prospects, while undermining providers' attempts at continuity of care; moreover, participants cited the "War on Drugs" as an overarching impediment to effective substance use treatment, not least for its role in perpetuating stigma against PWUO.

CONCLUSIONS

Interestingly, while an overwhelming majority of participants named stigma as a barrier to treatment at every level, most also articulated stigmatizing beliefs around PWUO. Namely, providers evoked one element of stigma - blameworthiness - in their contention that many PWUO are inadequately motivated to recover. In addition to adding further complexity to MOUD barriers research, this study troubles the notion that professional training and education on the disease model of addiction serve to eradicate stigma.

Patient's and healthcare provider's experiences with Opioid Maintenance Treatment (OMT): a qualitative evidence synthesis

BACKGROUND

Opioid Maintenance Treatment (OMT) is the gold standard for people with opioid dependence. However, drop-out rates are high, and many patients do not reach desired outcomes. Understanding patients' and healthcare providers' experiences with the treatment can provide valuable information to improve the quality of OMT and to increase acceptability and accessibility of services. The aim of this systematic review is to explore and synthesise the experiences of OMT among persons with opioid dependence and health care providers, to inform policy makers and practitioners on how to improve OMT outcomes.

METHODS

We conducted a qualitative evidence synthesis. We systematically searched in electronic databases (CINAHL, Embase, MEDLINE, and nordic databases) and searched for grey literature. As we identified many studies that met our inclusion criteria, we purposively sampled a manageable number of studies to include in this review. Two researchers independently extracted and coded data from the included studies and used the Andersen's healthcare utilization model to organize and develop codes. We assessed the methodological limitations of the studies, and our confidence in the findings using GRADE CERQual.

RESULTS

We retrieved 56 relevant studies and purposively sampled 24 qualitative studies of patients' and healthcare providers' experiences with OMT. Our analyses resulted in six main themes: (1) External stigma prevents engagement and retention in treatment, (2) Being identified as in OMT contributed to an increased experience of stigma (3) Inadequate knowledge and expertise among healthcare providers affected patients' treatment experiences, (4) Quality of communication between personnel and patients impacts patients' engagement with treatment and treatment outcomes, (5) Patients wanted help with many aspects of their lives not just medication, and (6) Balancing positive expectations of OMT with treatment stigma. We found that stigma was an overarching theme across these themes.

CONCLUSION

Our findings suggest that OMT could be more beneficial for patients if treatment programs prioritize efforts to diminish societal and OMT provider stigma and find strategies to better address patient needs. Initiatives should focus on improving treatment knowledge among providers, encouraging the use of client perspectives, considering the context of family members, and establishing a more holistic and flexible treatment environment.

Leveraging prescription monitoring program data to evaluate the implementation of buprenorphine telehealth flexibilities: An interrupted time series analysis in Texas

Background

In March 2020, policy changes by the Substance Abuse and Mental Health Services Administration and the Drug Enforcement Administration aimed to maintain access to office-based opioid treatment services by easing telehealth buprenorphine prescribing restrictions. However, the effectiveness of these changes remains largely unmeasured. The objective of this study was to measure the effectiveness of COVID-19-related telehealth flexibilities in an all-payer cohort from the Texas Prescription Monitoring Program.

Methods

Using Texas Prescription Monitoring Program data, we identified oral buprenorphine and buprenorphine/naloxone prescriptions dispensed in Texas between September 1, 2019, and September 26, 2020. Weekly counts of prescriptions, prescribing physicians, and dispensing pharmacies were analyzed. An autoregressive integrated moving average (ARIMA) model estimated changes in prescription volume between pre-implementation (September 1, 2019 - February 15, 2020) and post-implementation (April 12, 2020 - September 26, 2020) periods.

Results

Pre-flexibility, an average of 8898 (SD: 342) buprenorphine prescriptions were dispensed to 7829 (SD: 326) patients weekly. This declined to 8360 (SD: 247) prescriptions and 7661 (SD: 229) patients post-flexibility. Adjusted for seasonality, this represented a statistically significant average decline of -257.27 (95% CI: -426.06, -88.49) patients and -647.01 (95% CI: -856.67, -437.36) prescriptions per week.

Discussion

Our results suggest a modest decline in buprenorphine dispensing volume early in the COVID-19 pandemic. While difficult to assess its significance, it can be assumed that telehealth flexibilities mitigated a potentially larger decline. Future research should explore system and individual-level barriers to telehealth utilization.

Substance use disorders in hospice palliative care: A narrative review of challenges and a case for physician intervention

OBJECTIVES

Substance use disorders (SUDs) are frequently encountered in hospice palliative care (HPC) and pose substantial quality-of-life issues for patients. However, most HPC physicians do not directly treat their patients' SUDs due to several institutional and personal barriers. This review will expand upon arguments for the integration of SUD treatment into HPC, will elucidate challenges for HPC providers, and will provide recommendations that address these challenges.

METHODS

A thorough review of the literature was conducted. Arguments for the treatment of SUDs and recommendations for physicians have been synthesized and expanded upon.

RESULTS

Treating SUD in HPC has the potential to improve adherence to care, access to social support, and outcomes for pain, mental health, and physical health. Barriers to SUD treatment in HPC include difficulties with accurate assessment, insufficient training, attitudes and stigma, and compromised pain management regimens. Recommendations for physicians and training environments to address these challenges include developing familiarity with standardized SUD assessment tools and pain management practice guidelines, creating and disseminating visual campaigns to combat stigma, including SUD assessment and intervention as fellowship competencies, and obtaining additional training in psychosocial interventions.

SIGNIFICANCE OF RESULTS

By following these recommendations, HPC physicians can improve their competence and confidence in working with individuals with SUDs, which will help meet the pressing needs of this population.

Healthcare provider perspectives on emergency department-initiated buprenorphine/naloxone: a qualitative study

BACKGROUND

Take-home buprenorphine/naloxone is an effective method of initiating opioid agonist therapy in the Emergency Department (ED) that requires ED healthcare worker buy-in for large-scale implementation. We aimed to investigate healthcare workers perceptions of ED take-home buprenorphine/naloxone, as well as barriers and facilitators from an ED healthcare worker perspective.

METHODS

In the context of a take-home buprenorphine/naloxone feasibility study at a tertiary care teaching hospital we conducted a descriptive qualitative study. We conducted one-on-one in person or telephone interviews and focus groups with ED healthcare workers who cared for patients given take-home buprenorphine/naloxone in the feasibility study at Vancouver General Hospital from July 2019 to March 2020. We conducted 37 healthcare worker interviews from December 2019 to July 2020. We audio recorded interviews and focus groups and transcribed them verbatim. We completed interviews until we reached thematic saturation.

DATA ANALYSIS

We inductively coded a sample of transcripts to generate a provisional coding structure and to identify emerging themes, which were reviewed by our multidisciplinary team. We then used the final coding structure to analyze the transcripts. We present our findings descriptively.

RESULTS

Participants identified a number of context-specific facilitators and barriers to take-home buprenorphine/naloxone provision in the ED. Participants highlighted ED conditions having either facilitative or prohibitive effects: provision of buprenorphine/naloxone was feasible when ED volume was low and space was available but became less so as ED volume increased and space decreased. Similarly, participants noted that patient-related factors could have a facilitative or prohibitive effect, such as willingness to wait (willing to stay in the ED for study-related activities and buprenorphine/naloxone initiation activities), receptiveness to buprenorphine/naloxone, and comprehension of the instructions. As for staff-related factors, time was identified as a consistent barrier. Time included time available and time required to initiate buprenorphine/naloxone (including time building rapport). Healthcare worker familiarity with buprenorphine/naloxone was noted as either a facilitating factor or a barrier, and healthcare workers indicated that ongoing training would have been advantageous. Many healthcare workers identified that the ED is an important first point of contact for the target patient population.

CONCLUSION

Integrating a buprenorphine/naloxone program into ED care requires organizational supports (e.g., for managing buprenorphine/naloxone within limitations of ED volume, space, and time), and ongoing education of healthcare workers to minimize identified barriers.

Internal Medicine Resident Addiction Training at the Veteran's Health Administration: A Qualitative Evaluation of Site Directors' Response to the 2022 ACGME Requirements

BACKGROUND

Substance use disorders (SUDs) are prevalent in the USA yet remain dramatically undertreated. To address this care gap, the Accreditation Council for Graduate Medical Education (ACGME) approved revisions to the Program Requirements for Graduate Medical Education (GME) in Internal Medicine, effective July 1, 2022, requiring addiction medicine training for all internal medicine (IM) residents. The Veterans Health Administration (VHA) is a clinical training site for many academic institutions that sponsor IM residencies. This focus group project evaluated VHA IM residency site directors' perspectives about providing addiction medical education within VHA IM training sites.

OBJECTIVE

To better understand the current state, barriers to, and facilitators of IM resident addiction medicine training at VHA sites.

DESIGN

This was a qualitative evaluation based on semi-structured video-based focus groups.

PARTICIPANTS

Participants were VHA IM site directors based at a VHA hospital or clinic throughout the USA.

APPROACH

Focus groups were conducted using a semi-structured group interview guide. Two investigators coded each focus group independently, then met to create a final adjudicated coding scheme. Thematic analysis was used to identify key themes.

KEY RESULTS

Forty-three participants from 38 VHA sites participated in four focus groups (average size: 11 participants). Six themes were identified within four pre-defined categories. Current state of training: most VHA sites offered no formal training in addiction medicine for IM residents. Barriers: addiction experts are often located outside of IM settings, and ACGME requirements were non-specific. Facilitators: clinical champions help support addiction training. Desired next steps: participants desired incentives to train or hire local champions and a pre-packaged didactic curriculum.

CONCLUSIONS

Developing competent clinical champions and leveraging VHA addiction specialists from non-IM settings would create more addiction training opportunities for IM trainees at VHA sites. These insights can likely be applied to IM training at non-VHA sites.

Traumatic Brain Injury and Opioids: Twin Plagues of the Twenty-First Century

Traumatic brain injury (TBI) and opioid use disorder (OUD) comprise twin plagues causing considerable morbidity and mortality worldwide. As interactions between TBI and OUD are to our knowledge uncharted, we review the possible mechanisms by which TBI may stimulate the development of OUD and discuss the interaction or crosstalk between these two processes. Central nervous system damage due to TBI appears to drive adverse effects of subsequent OUD and opioid use/misuse affecting several molecular pathways. Pain, a neurological consequence of TBI, is a risk factor that increases the likelihood of opioid use/misuse after TBI. Other comorbidities including depression, anxiety, posttraumatic stress disorder, and sleep disturbances are also associated with deleterious outcomes. We examine the hypothesis that a TBI "first hit" induces a neuroinflammatory process involving microglial priming, which, on a second hit related to opioid exposure, exacerbates neuroinflammation, modifies synaptic plasticity, and spreads tau aggregates to promote neurodegeneration. As TBI also impairs myelin repair by oligodendrocytes, it may reduce or degrade white matter integrity in the reward circuit resulting in behavioral changes. Along with approaches focused on specific patient symptoms, understanding the CNS effects following TBI offers a promise of improved management for individuals with OUD.

Independent community pharmacists' attitudes and intentions toward dispensing buprenorphine/naloxone for opioid use disorder

BACKGROUND

Buprenorphine/naloxone (BUP/NX) for opioid use disorder (OUD) is associated with positive health outcomes; however, challenges accessing prescribed BUP/NX at community pharmacies have been identified.

OBJECTIVE

The theory of planned behavior was applied to determine whether independent community pharmacists' attitudes toward dispensing BUP/NX for OUD predict intentions to dispense.

METHODS

A 40-item survey was administered to 185 Texas Community Pharmacy Enhanced Services Network pharmacists. The survey assessed intentions to dispense BUP/NX (3 items), attitudes toward BUP/NX (24 items), current barriers to dispensing BUP/NX (2 items), and demographics (10 items). Inferential statistics determined associations among pharmacists' attitudes, practice setting characteristics, and intentions to dispense BUP/NX. Regression analysis determined whether attitude predicted intention to dispense BUP/NX, controlling for practice setting and demographic characteristics.

RESULTS

Responses were obtained from 82 community independent pharmacists (response rate = 44%). Respondents were predominantly non-Hispanic white (45.8%) and women (56.6%) and practiced in pharmacies with an average 1129.1 (± 1034.5) dispensed prescriptions/week. Pharmacists had positive intentions (6.2 ± 3.5) and attitudes (14.4 ± 24.9) toward dispensing BUP/NX and attitudes did not predict intentions to dispense (P = 0.330). Positive drivers of attitude were related to improving patient outcomes, fulfilling a community need, and absence of conflicts with pharmacists' personal and religious beliefs. A negative driver of attitude was financial reimbursement/loss. Pharmacists dispensing 2000 or more prescriptions/week had higher intentions (b = 3.22, P = 0.014) to dispense than those dispensing less than 500 prescriptions/week. The most common barrier to dispense BUP/NX was "refill was too soon" (54.8%).

CONCLUSION

Community independent pharmacists had positive attitudes toward and intentions of dispensing BUP/NX for OUD. However, attitudes did not predict intentions to dispense. Negative drivers of attitudes were related to factors not within pharmacists' control, such as time to refill or financial reimbursement.Future studies focused on community pharmacy-based access to BUP/NX are warranted to elucidate issues that are impactful in improving pharmacists' dispensing intentions and behavior.

Evaluation of the New England Office Based Addiction Treatment ECHO: A Tool for Strengthening the Addiction Workforce

INTRODUCTION

Reducing substance-related morbidity requires an educated and well-supported workforce. The New England Office Based Addiction Treatment Extension for Community Healthcare Outcomes (NE OBAT ECHO) began in 2019 to support community-based addiction care teams through virtual mentoring and case-based learning. We sought to characterize the program's impact on the knowledge and attitudes of NE OBAT ECHO participants.

METHODS

We conducted an 18-month prospective evaluation of the NE OBAT ECHO. Participants registered for 1 of 2 successive ECHO clinics. Each 5-month clinic included ten 1.5-hour sessions involving brief didactic lectures and de-identified patient case presentations. Participants completed surveys at Month-0, -6, -12, and -18 to assess attitudes about working with patients who use drugs and evidence based practices (EBPs), stigma toward people who use drugs, and addiction treatment knowledge. We compared outcomes using 2 approaches: (i) between-groups, which involved comparing the first intervention group to the delayed intervention (comparison) group, and (ii) within-groups, which involved comparing outcomes at different time points for all participants. In the within-group approach, each participant acted as their own control.

RESULTS

Seventy-six health professionals participated in the NE OBAT ECHO, representing various roles in addiction care teams. Approximately half (47% [36/76]) practiced primary care, internal, or family medicine. The first intervention group reported improved job satisfaction and openness toward EBPs compared to the delayed intervention group. Within-group analyses revealed that ECHO participation was associated with increased positive perceptions of role adequacy, support, legitimacy, and satisfaction 6 months following program completion. No changes were identified in willingness to adopt EBPs or treatment knowledge. Stigma toward people who use drugs was persistent in both groups across time points.

CONCLUSIONS

NE OBAT ECHO may have improved participants' confidence and satisfaction providing addiction care. ECHO is likely an effective educational tool for expanding the capacity of the addiction workforce.

Buprenorphine use and courses of care for opioid use disorder treatment within the Veterans Health Administration

BACKGROUND

Retention of patients in buprenorphine medication treatment for opioid use disorder (B-MOUD) reduces harms associated with opioid use disorder (OUD). We sought to characterize the patients receiving B-MOUD and courses of B-MOUD in a large healthcare system.

METHODS

We conducted a retrospective, open cohort study of patients with OUD who either did or did not receive B-MOUD courses within the Veterans Health Administration (VHA) from January 2006 through July 2019, using VHA clinical data. We compared patients receiving or not receiving B-MOUD, characterized B-MOUD courses (e.g., length and doses), and examined persistence, across patient characteristics, over time. We used analyses for normally or non-normally distributed continuous variables, categorical data, and persistence over time (Kaplan-Meier persistence curves).

RESULTS

We identified 255,726 Veterans with OUD; 40,431 (15.8%) had received 63,929 B-MOUD courses. Compared to patients with OUD without B-MOUD, patients with B-MOUD were younger, more often of white race, and had more co-morbidities. The frequency of new B-MOUD starts and prevalent B-MOUD patients ranged from 1550 and 1989 in 2007 to 8146 and 16,505 in 2018, respectively. The median duration of B-MOUD was 157 (IQR: 37-537) days for all courses and 33.8% patients had more than one course. The average proportion days covered was 90% (SD: 0.15), and the average prescribed daily dose was 13.44 (SD: 6.5).

CONCLUSIONS

Within a VHA B-MOUD cohort, courses increased more than 10-fold from 2006 to 2016 with nearly half of patients experiencing multiple courses. Patient demographics seem to dictate the length of courses.

Co-occurring implementation strategies: The effects of academic detailing for opioid use disorder campaign on the advancing pharmacological treatments for opioid use disorder (ADaPT-OUD) study

Background

Barriers at the system, clinician, and patient level limit access to medications for opioid use disorder (MOUD). The Advancing Pharmacological Treatments for Opioid Use Disorder (ADaPT-OUD) study implemented an external facilitation strategy within the Veterans Health Administration (VHA) aimed at facility-level barriers to improve uptake of MOUD. During ADaPT-OUD, an independent Academic Detailing Services Opioid Agonist Treatment of OUD Campaign was co-occurring and aimed to increase evidence-based practice for OUD at the clinician level. While both these initiatives aim to increase MOUD reach, they address different barriers and did not intentionally collaborate. Thus, understanding the interaction between these two independent implementation initiatives and their effect on MOUD reach will further inform and mold future implementation efforts of MOUD.

Methods

This was a secondary analysis of the ADaPT-OUD study that included 35 VHA facilities in the lowest quartile of MOUD reach; eight received the ADaPT-OUD external facilitation and 27 matched sites received implementation as usual. The number of academic detailing (AD) visits during ADaPT-OUD was used as a proxy for the intensity of Academic Detailing for OUD Campaign activity. The interaction between external facilitation status and AD intensity was evaluated by comparing the change in facility-level MOUD reach.

Results

There was a general increase in the number of AD visits, in both external facilitation and implementation as usual sites, over the course of ADaPT-OUD's implementation period. A non-statistically significant, positively sloped, linear relationship was observed between average number of AD visits per quarter and change in MOUD reach in facilities also receiving ADaPT-OUD external facilitation that was not observed in the implementation as usual sites.

Conclusion

Co-occurring initiatives focusing on different barriers to MOUD access have the potential to further increase MOUD in low-performing facilities, but further research into timing, quality, and collaboration between initiatives are warranted.

Advancing Pharmacological Treatments for Opioid Use Disorder (ADaPT-OUD): an Implementation Trial in Eight Veterans Health Administration Facilities

BACKGROUND

Identifying effective strategies to improve access to medication treatments for opioid use disorder (MOUD) is imperative. Within the Veterans Health Administration (VHA), provision of MOUD varies significantly, requiring development and testing of implementation strategies that target facilities with low provision of MOUD.

OBJECTIVE

Determine the effectiveness of external facilitation in increasing the provision of MOUD among VHA facilities with low baseline provision of MOUD compared to matched controls.

DESIGN

Pre-post, block randomized study designed to compare facility-level outcomes in a stratified sample of eligible facilities. Four blocks (two intervention facilities in each) were defined by median splits of both the ratio of patients with OUD receiving MOUD and number of patients with OUD not currently receiving MOUD (i.e., number of actionable patients). Intervention facilities participated in a 12-month implementation intervention.

PARTICIPANTS

VHA facilities in the lowest quartile of MOUD provision (35 facilities), eight of which were randomly assigned to participate in the intervention (two per block) with twenty-seven serving as matched controls by block.

INTERVENTION

External facilitation included assessment of local barriers/facilitators, formation of a local implementation team, a site visit for action planning and training/education, cross-facility quarterly calls, monthly coaching calls, and consultation.

MAIN MEASURES

Pre- to post-change in the facility-level ratio of patients with an OUD diagnosis receiving MOUD compared to control facilities.

KEY RESULTS

Intervention facilities significantly increased the ratio of patients with OUD receiving MOUD from an average of 18% at baseline to 30% 1 year later, with an absolute difference of 12% (95% confidence interval [CI]: 6.6%, 17.0%). The difference in differences between intervention and control facilities was 3.0% (95% CI: - 0.2%. 6.7%). The impact of the intervention varied by block, with smaller, less complex facilities more likely to outperform matched controls.

CONCLUSIONS

Intensive external facilitation improved the adoption of MOUD in most low-performing facilities and may enhance adoption beyond other interventions less tailored to individual facility contexts.

Education as drug policy: A realist synthesis of continuing professional development for opioid agonist therapy

BACKGROUND

Continuing professional development (CPD) for opioid agonist therapy (OAT) has been identified as a key health policy strategy to improve care for people living with opioid use disorder (OUD) and to address rising opioid-related harms. To design and deliver effective CPD programs, there is a need to clarify how they work within complex health system and policy contexts. This review synthesizes the literature on OAT CPD programs and educational theory to clarify which interventions work, for whom, and in what contexts.

METHODS

A systematic review and realist synthesis of evaluations of CPD programs focused on OAT was conducted. This included record identification and screening, theory familiarization, data collection, analysis, expert consultation, and iterative context-intervention-mechanism-outcome (CIMO) configuration development.

RESULTS

Twenty-four reports comprising 21 evaluation studies from 5 countries for 3373 providers were reviewed. Through iterative testing of included studies with relevant theory, five CIMO configurations were developed. The programs were categorized by who drove the learning outcomes (i.e., system/policy, instructor, learner) and their spheres of influence (i.e., micro, meso, macro). There was a predominance of instructor-driven programs driving change at the micro level, with few policy-driven macro-influential programs, inconsistent with the promotion of CPD as a clear opioid crisis policy-level intervention.

CONCLUSION

OAT CPD is challenged by mismatches in program justifications, objectives, activities, and outcomes. Depending on how these program factors interact, OAT CPD can operate as a barrier or facilitator to OUD care. With more deliberate planning and consideration of program theory, programs more directly addressing diverse learner and system needs may be developed and delivered. OAT CPD as drug policy does not operate in isolation; programs may feed into each other and intercalate with other policy initiatives to have micro, meso, and macro impacts on educational and population health outcomes.

Barriers to Buprenorphine Prescribing for Opioid Use Disorder in Hospice and Palliative Care

CONTEXT

Hospice and palliative care (HPC) clinicians increasingly care for patients with concurrent painful serious illness and opioid use disorder (OUD) or opioid misuse; however, only a minority of HPC clinicians have an X-waiver license or actively use it to prescribe buprenorphine as medication treatment for OUD.

OBJECTIVES

To understand barriers for HPC clinicians to obtaining an X-waiver and prescribing buprenorphine as medication treatment for OUD.

METHODS

We performed content analysis on 100 survey responses from members of the national Buprenorphine Peer Support Network, a group of HPC clinicians interested in buprenorphine, on X-waiver status, barriers to obtaining an X-waiver, and barriers to active prescribing.

RESULTS

Of 100 HPC clinicians surveyed, only 26 of 57 HPC clinicians with X-waivers had ever prescribed. Prominent barriers included discomfort managing concurrent pain, buprenorphine, and OUD; concerns about impacts on practice; unsupportive practice culture; insufficient practice support; patient facing challenges; and cumbersome regulatory policies.

CONCLUSION

Despite HPC clinicians' interest in buprenorphine prescribing for OUD, several steps are needed to facilitate the practice, including clinician education tailored to pain and to clinical challenges faced by HPC clinicians, mentorship on buprenorphine use, and cultural and practice changes to dismantle systemic stigma towards addiction. We propose evidence-based steps derived from our survey findings that individual clinicians, HPC leaders, and national HPC organizations can take to improve care for patients with painful serious illness and OUD.

Expanding access to medications for opioid use disorder through locally-initiated implementation

Background

Despite demonstrated efficacy, medication treatment for opioid use disorder (MOUD) remain inaccessible to many patients, with barriers identified at the individual, clinic and system level. A wide array of implementation strategies have guided efforts to expand access to MOUD, with most centered around externally-facilitated approaches to practice change. While effective, such approaches may be inaccessible to those clinics and systems that lack the resources necessary to partner with an external team, suggesting a need to identify and describe change-processes that are internally developed and promoted.

Methods

Guided by the Consolidated Framework for Implementation Research (CFIR), we utilized qualitative interviews and ethnographic observation to investigate the planning, design and implementation of a locally-initiated process to expand access to MOUD within one health care system. All study documents were coded by a primary coder and secondary reviewer using a codebook designed for use with the CFIR. To analyze data, we reviewed text tagged by key codes, compared these textual excerpts both across and within documents, and organized findings into themes. Processes identified were mapped to established implementation science constructs and strategies.

Results

Interviews with clinicians and administrators (n = 9) and ethnographic observation of planning meetings (n = 3) revealed how a self-appointed local team developed, established broad support for, and successfully implemented a Primary Care-based Buprenorphine Clinic and E-Consult Service to expand access to MOUD to patients across the health care system. First, national and local policy changes—including altered clinical practice guidelines, performance pay incentives regarding opioid prescribing, and a directive from VA Central Office increased individual staff and administrators’ perception of the need for change and willingness to invest time and resources. Then, a self-appointed interdisciplinary team utilized cross-clinic meetings and information gathering to identify appropriate, and widely supported, models of care delivery and care consultation. Finally, the team increased staff investment in these change efforts by bringing them into the planning process and encouraging collaborative problem solving.

Conclusions

This study reveals how a local team developed and built widespread support for new processes of care that were tailored to local needs and well-positioned for sustainability over time.

Champions Among Us: Leading Primary Care to the Forefront of Opioid Use Disorder Treatment

Despite more than a decade of investment in opioid use disorder (OUD) treatment infrastructure, the year 2020 saw the highest mortality related to opioid overdose in American history. Treatment access remains critically limited, with less than half of people living with OUD receiving any treatment. Primary care has been referred to as the "sleeping giant" of addiction care, as few primary care doctors currently prescribe medications to treat OUD. The "clinical champions" framework is a tool that has shown promise in creating the type of mentorship and culture change necessary to expand uptake of medication-based OUD treatment among primary care providers. The early success of this model and the increased availability of tools for broad implementation warrant further investment as a means of leading primary care into a larger role in combatting the opioid addiction epidemic.

The Association Between Scope of Practice Regulations and Nurse Practitioner Prescribing of Buprenorphine After the 2016 Opioid Bill

This article examines the relationship between federal regulations, state scope-of-practice regulations on nurse practitioners (NPs), and buprenorphine prescribing patterns using pharmacy claims data from Optum's deidentified Clinformatics Data Mart between January 2015 and September 2018. The county-level proportion of patients filling prescriptions written by NPs was low even after the 2016 Comprehensive Addiction and Recovery Act (CARA), 2.7% in states that did not require physician oversight of NPs, and 1.1% in states that did. While analyses in rural counties showed higher rates of buprenorphine prescriptions written by NPs, rates were still considerably low: 3.7% in states with less restrictive regulations and 1.1% in other states. These results indicate that less restrictive scope-of-practice regulations are associated with greater NP prescribing following CARA. The small magnitude of the changes indicates that federal attempts to expand treatment access through CARA have been limited.

Roles and Perceptions of Nurses During Implementation of a Medication Treatment for Opioid Use Disorder National Initiative

BACKGROUND

In the United States, a national priority exists to improve access to medication treatment for opioid use disorder (MOUD). Nurses can be an essential component of that care. We examined the perceptions and evolving roles of nurses in a national Veterans Health Administration (VHA) initiative designed to improve MOUD access within general medical settings.

METHODS

From April 15, 2021, to June 16, 2021, we recruited nurses participating in VHA's Stepped Care for Opioid Use Disorder Train the Trainer Initiative-a national program intending to implement MOUD in general medical settings-to participate in an interview about their roles, perceptions, and experiences. The respondents answered our inquiries through an interview or responded to an email solicitation with written responses, which were then recorded, transcribed, and independently coded to identify themes.

RESULTS

Nurses from 10 VHA facilities participated in an interview (n = 7) or completed the questionnaire (n = 4). Inadequate staffing, high patient-to-provider ratios, and time constraints were identified as barriers to MOUD care. Mentorship activities, existing VHA informational resources, and patients' willingness to accept treatment were identified as facilitators of MOUD care. The Stepped Care for Opioid Use Disorder Train the Trainer Initiative processes were acknowledged to promote role confidence, which in turn increased job satisfaction and empowered nurses to become content experts. Respondents often identified nurses as local lead facilitators in MOUD care.

CONCLUSIONS

In a national initiative to implement MOUD within general medical settings, nurses identified several barriers and facilitators to MOUD implementation. Nurses play vital collaborative care roles in enhancing access to MOUD.

Toward a Typology of Office-based Buprenorphine Treatment Laws: Themes From a Review of State Laws

OBJECTIVES

Buprenorphine is a gold standard treatment for opioid use disorder (OUD). Some US states have passed laws regulating office-based buprenorphine treatment (OBBT) for OUD, with requirements beyond those required in federal law. We sought to identify themes in state OBBT laws.

METHODS

Using search terms related to medications for OUD, we searched Westlaw software for state regulations and statutes in 51 US jurisdictions from 2005 to 2019. We identified and inductively analyzed OBBT laws for themes.

RESULTS

Since 2005, 10 states have passed a total of 181 OBBT laws. We identified the following themes: (1) provider credentials: state licensure for OBBT providers and continuing medical education requirements; (2) new patients: objective symptoms patients must have before receiving OBBT and exceptions for special populations; (3) educating patients: general informed consent requirements, and specific information to provide; (4) counseling: minimum counselor credentials, minimum counseling frequency, counseling alternatives; (5) patient monitoring: required prescription drug monitoring checks, frequency of drug screening, and responses to lost/stolen medications; (6) enhanced clinician monitoring: evidence-based treatment protocols, minimum clinician-patient contact frequency, health assessment requirements, and individualized treatment planning; and (7) patient safety: reconciling prescriptions, dosage limitations, naloxone coprescribing, tapering, and office closures.

CONCLUSIONS

Some laws codify practices for which scientific consensus is lacking. Additionally, some OBBT laws resemble opioid treatment programs and pain management regulations. Results could serve as the basis for a typology of office-based treatment laws, which could facilitate empirical examination of policy impacts on treatment access and quality.

E-consultation for medications to treat opioid use disorders: a pilot study

BACKGROUND AND OBJECTIVES

An electronic consultation to provide expert guidance on medications to treat opioid use disorders [MOUD] was piloted.

METHODS

Medical record review of the first 100 unique patients receiving consultation with 6-month follow-up. Descriptive statistics, chi-square, and Fisher's exact tests of significance were calculated as appropriate.

RESULTS

Most consultation requests originated from inpatient psychiatry (66%). Patients (67%) and consultants (33%) preferred buprenorphine/naloxone most often (p < 0.0001). Half of the patients received MOUD prior to discharge. Three quarters of the half who kept their first outpatient appointments received the recommended treatment (p < 0.0001). At 6 months, four patients died and four others overdosed only. Type of MOUD was not associated with either overdose or death, but those who overdosed used cannabis, sedative-hypnotics, or stimulants (all, p < 0 .05).

DISCUSSION AND CONCLUSIONS

Guidance for MOUD offered via e-consultation may have increased outpatient treatment engagement following inpatient treatment.

Are x-waiver trainings enough? Facilitators and barriers to buprenorphine prescribing after x-waiver trainings

BACKGROUND

In the United States, an x-waiver credential is necessary to prescribe buprenorphine medication treatment for opioid use disorder (B-MOUD). Historically, this process has required certified training, which could be a barrier to obtaining an x-waiver and subsequently prescribing. To address this barrier, the US recently removed the training requirement for some clinicians. We sought to determine if clinicians who attended x-waiver training went on to obtain an x-waiver and prescribe B-MOUD, and to examine what facilitated or impeded B-MOUD prescribing.

METHODS

In September 2020, we conducted a cross-sectional, electronic survey of attendees of 15 in-person x-waiver pieces of training from June 2018 to January 2020 within the Veterans Health Administration (VHA). Of the attendees (n = 321), we surveyed current VHA clinicians who recalled taking the training. The survey assessed whether clinicians obtained the x-waiver, had prescribed B-MOUD, and barriers or facilitators that influenced B-MOUD prescribing.

RESULTS

Of 251 eligible participants, 62 (24.7%) responded to the survey, including 27 (43.5%) physicians, 16 (25.8%) advanced practice clinicians, and 12 (19.4%) pharmacists. Of the 43 clinicians who could prescribe, 29 (67.4%) had obtained their x-waiver and 16 (37.2%) had reported prescribing B-MOUD. Prominent barriers to prescribing B-MOUD included a lack of supporting clinical staff and competing demands on time. The primary facilitator to prescribing was leadership support.

CONCLUSIONS

Nine months after x-waiver training, two-thirds of clinicians with prescribing credentials had obtained their x-waiver and one-third were prescribing B-MOUD. Removing the x-waiver training may not have the intended policy effect as other barriers to B-MOUD prescribing persist.

Support Models for Addiction Related Treatment (SMART) for pregnant women: Study protocol of a cluster randomized trial of two treatment models for opioid use disorder in prenatal clinics

Introduction

The prevalence of opioid use disorder (OUD) in pregnancy increased nearly five-fold over the past decade. Despite this, obstetric providers are less likely to treat pregnant women with medication for OUD than non-obstetric providers (75% vs 91%). A major reason is many obstetricians feel unprepared to prescribe medication for opioid use disorder (MOUD). Education and support may increase prescribing and overall comfort in delivering care for pregnant women with OUD, but optimal models of education and support are yet to be determined.

Methods and analysis

We describe the rationale and conduct of a matched-pair cluster randomized clinical trial to compare the effectiveness of two models of support for reproductive health clinicians to provide care for pregnant and postpartum women with OUD. The primary outcomes of this trial are patient treatment engagement and retention in OUD treatment. This study compares two support models: 1) a collaborative care approach, based upon the Massachusetts Office-Based-Opioid Treatment Model, that provides practice-level training and support to providers and patients through the use of care managers, versus 2) a telesupport approach based on the Project Extension for Community Healthcare Outcomes, a remote education model that provides mentorship, guided practice, and participation in a learning community, via video conferencing.

Discussion

This clustered randomized clinical trial aims to test the effectiveness of two approaches to support practitioners who care for pregnant women with an OUD. The results of this trial will help determine the best model to improve the capacity of obstetrical providers to deliver treatment for OUD in prenatal clinics.

A national survey of barriers and facilitators to medications for opioid use disorder among legal-involved veterans in the Veterans Health Administration

Background: Medications for opioid use disorder (MOUD) are clinically effective at treating OUD among legal-involved populations. However, research shows that legal-involved veterans who receive care through the VHA have lower rates of MOUD use compared to non-legal-involved veterans. Education may be a key factor in intervention strategies to improve MOUD access. This study was a national survey of VHA staff to identify barriers to and facilitators of MOUD, as well as MOUD-related education needs for VHA staff, community partners, criminal justice partners, and legal-involved veterans. Method: A 98-item online survey was conducted to examine VHA staff perspectives (N = 218) around needed education, barriers to, and facilitators of MOUD for legal-involved veterans. Descriptive statistics were conducted and linear regression analyses were used to evaluate differences in perceptions by respondents' current position at the VHA and their VHA facility's rate of provision of MOUD among legal-involved veterans. Results: Respondents endorsed a need for education in all areas of MOUD (e.g., existing medications for the treatment of OUD) for VHA staff and providers, community partners, criminal justice partners, and legal-involved veterans. VHA staff perceived barriers to MOUD for legal-involved veterans to include stigma and complicated guidelines around MOUD and OUD treatment. Facilities with low rates of MOUD use highlighted barriers including MOUD conflicting with the philosophy of the local VHA facility and provider stigma toward patients with OUD. Perceptions of efficacy of MOUD differed by respondents' current position at the VHA such that substance use disorder treatment providers perceived buprenorphine and methadone as more effective compared to Veterans Justice Specialists. Conclusion: The results of this study suggest a need for an educational intervention emphasizing the evidence supporting use of MOUD as a lack of knowledge about these medications was considered a barrier to access, whereas gaining education about MOUD was a facilitator to access. Education strategies specifically tailored to address VHA facility-level differences may help address barriers to MOUD experienced by legal-involved veterans.

Evaluating buprenorphine prescribing and opioid-related health outcomes following the expansion the buprenorphine waiver program

AIMS

To evaluate associations between new types of buprenorphine waivers (nurse practitioner and physician assistant [NP/PA]; 275-patient limit [MD/DO-275]) and both buprenorphine prescribing and health outcomes.

METHODS

Using comprehensive county-level data from California 2010-2018, we modeled quarterly associations between numbers of NP/PA and MD/DO-275 waivers and rates of buprenorphine prescribing, opioid-related deaths, emergency department (ED) visits, and hospitalizations among all counties and separately among metropolitan and nonmetropolitan counties using Poisson regression models with county and quarter fixed effects and adjusting for time-varying covariates.

RESULTS

Each additional NP/PA and MD/DO-275 waiver was associated with a 2.6% (95%CI: 1.1-4.1%) and 5.8% (4.1-7.4%) increase in buprenorphine prescribing among nonmetropolitan counties, respectively. Each additional MD/DO-275 waiver was associated with a 2.8% (1.0%-4.6%) increase in buprenorphine among metropolitan counties. There were no statistically significant associations between NP/PA waivers and buprenorphine prescribing among metropolitan counties or among either waiver type and opioid-related health outcomes.

CONCLUSIONS

NP/PA waivers were associated with increased buprenorphine prescribing among nonmetropolitan counties and MD/DO-275 waivers were associated with increased buprenorphine prescribing among both metropolitan and nonmetropolitan counties.

Barriers and Facilitators to DATA Waivered Providers Prescribing Buprenorphine: A Qualitative Analysis Applying the Theory of Planned Behavior

Background: Provider beliefs about the treatment of people with addiction may influence their prescribing behavior. Objective: This study applied the Theory of Planned Behavior (TPB), to identify the salient beliefs of Drug Addiction Treatment Act of 2000 (DATA 2000) waivered providers, concerning prescribing buprenorphine to patients with Opioid Use Disorder (OUD). Methods: Texas buprenorphine providers participated in one of four online focus group discussions conducted in fall 2019. The focus group discussion were audio recorded and the total length was between 60-90 minutes. Thematic analysis was conducted to identify emerging themes and to categorize the behavioral, normative, and control beliefs related to buprenorphine prescribing. Results: Of the 14 total participants, 57% of the participants were male and annually treated between zero to sixty patients with buprenorphine. The codes generated were represented in thematic maps, specifying the positive or negative aspects of buprenorphine prescribing. Results indicate that providers' primary motivation to prescribe buprenorphine was, implementation of a whole-patient approach through collaboration with behavioral health providers, in the provision of medications for opioid use disorder (MOUD). Providers primary normative belief was the recognition of key members of the medical community and patients' families and friends as influential groups. Providers' control beliefs focused on their ability to use buprenorphine in different practice settings. Conclusion: These results indicate that buprenorphine access may be expanded by increasing support for DATA waivered providers from other parts of the healthcare system such as behavioral health providers and pharmacists. Implications for clinical practice and future research will be discussed.

Therapeutic relationships between Veterans and buprenorphine providers and effects on treatment retention

OBJECTIVE

To examine the extent to which there was any therapeutic relationship between Veterans and their initial buprenorphine provider and whether the presence of this relationship influenced treatment retention.

DATA SOURCES

National, secondary administrative data used from the Veterans Health Administration (VHA), 2008-2017.

STUDY DESIGN

Retrospective cohort study. The primary exposure was a therapeutic relationship between the Veteran and buprenorphine provider, defined as the presence of a previous visit or medication prescribed by the provider in the 2 years preceding buprenorphine treatment initiation. The primary outcome was treatment discontinuation, evaluated as 14 days of absence of medication from initiation through 1 year.

DATA COLLECTION/EXTRACTION METHODS

Adult Veterans (age ≥ 18 years) diagnosed with opioid use disorder and treated with buprenorphine or buprenorphine/naloxone within the VHA system were included in this study. We excluded those receiving buprenorphine patches, those with documentation of a metastatic tumor diagnosis within 2 years prior to buprenorphine initiation, and those without geographical information on rurality.

PRINCIPAL FINDINGS

A total of 28,791 Veterans were included in the study. Within the overall study sample, 56.3% (n = 16,206) of Veterans previously had at least one outpatient encounter with their initial buprenorphine provider, and 24.9% (n = 7174) of Veterans previously had at least one prescription from that provider in the 2 years preceding buprenorphine initiation. There was no significant or clinically meaningful association between therapeutic relationship history and treatment retention when defined as visit history (aHR: 0.99; 95% CI: 0.96, 1.02) or medication history (aHR: 1.03; 95% CI: 1.00, 1.07).

CONCLUSIONS

Veterans initiating buprenorphine frequently did not have a therapeutic history with their initial buprenorphine provider, but this relationship was not associated with treatment retention. Future work should investigate how the quality of Veteran-provider therapeutic relationships influences opioid use dependence management and whether eliminating training requirements for providers might affect access to buprenorphine, and subsequently, treatment initiation and retention.

Stepped Care for Opioid Use Disorder Train the Trainer (SCOUTT) initiative: Expanding access to medication treatment for opioid use disorder within Veterans Health Administration facilities

The US is confronted with a rise in opioid use disorder (OUD), opioid misuse, and opioid-associated harms. Medication treatment for opioid use disorder (MOUD)-including methadone, buprenorphine and naltrexone-is the gold standard treatment for OUD. MOUD reduces illicit opioid use, mortality, criminal activity, healthcare costs, and high-risk behaviors. The Veterans Health Administration (VHA) has invested in several national initiatives to encourage access to MOUD treatment. Despite these efforts, by 2017, just over a third of all Veterans diagnosed with OUD received MOUD. VHA OUD specialty care is often concentrated in major hospitals throughout the nation and access to this care can be difficult due to geography or patient choice. Recognizing the urgent need to improve access to MOUD care, in the Spring of 2018, the VHA initiated the Stepped Care for Opioid Use Disorder, Train the Trainer (SCOUTT) Initiative to facilitate access to MOUD in VHA non-SUD care settings. The SCOUTT Initiative's primary goal is to increase MOUD prescribing in VHA primary care, mental health, and pain clinics by training providers working in those settings on how to provide MOUD and to facilitate implementation by providing an ongoing learning collaborative. Thirteen healthcare providers from each of the 18 VHA regional networks across the VHA were invited to implement the SCOUTT Initiative within one facility in each network. We describe the goals and initial activities of the SCOUTT Initiative leading up to a two-day national SCOUTT Initiative conference attended by 246 participants from all 18 regional networks in the VHA. We also discuss subsequent implementation facilitation and evaluation plans for the SCOUTT Initiative. The VHA SCOUTT Initiative could be a model strategy to implement MOUD within large, diverse health care systems.

Clinical leaders and providers' perspectives on delivering medications for the treatment of opioid use disorder in Veteran Affairs' facilities

BACKGROUND

Improving access to medication treatment of opioid use disorder (MOUD) is a national priority, yet common modifiable barriers (e.g., limited provider knowledge, negative beliefs about MOUD) often challenge implementation of MOUD delivery. To address these barriers, the VA launched a multifaceted implementation intervention focused on planning and educational strategies to increase MOUD delivery in 18 medical facilities. The purpose of this investigation was to determine if a multifaceted intervention approach to increase MOUD delivery changed providers' perceptions about MOUD over the first year of implementation.

METHODS

Cross-disciplinary teams of clinic providers and leadership from primary care, pain, and mental health clinics at 18 VA medical facilities received invitations to complete an anonymous, electronic survey prior to intervention launch (baseline) and at 12- month follow-up. Responses were summarized using descriptive statistics, and changes over time were compared using regression models adjusted for gender and prescriber status, and clustered on facility. Responses to open-ended questions were thematically analyzed using a template analysis approach.

RESULTS

Survey response rates at baseline and follow-up were 57.1% (56/98) and 50.4% (61/121), respectively. At both time points, most respondents agreed that MOUD delivery is important (94.7 vs. 86.9%), lifesaving (92.8 vs. 88.5%) and evidence-based (85.2 vs. 89.5%). Over one-third (37.5%) viewed MOUD delivery as time-consuming, and only 53.7% affirmed that clinic providers wanted to prescribe MOUD at baseline; similar responses were seen at follow-up (34.5 and 52.4%, respectively). Respondents rated their knowledge about OUD, comfort discussing opioid use with patients, job satisfaction, ability to help patients with OUD, and support from colleagues favorably at both time points. Respondents' ratings of MOUD delivery filling a gap in care were high but declined significantly from baseline to follow-up (85.7 vs. 73.7%, p < 0.04). Open-ended responses identified implementation barriers including lack of support to diagnose and treat OUD and lack of time.

CONCLUSIONS

Although perceptions about MOUD generally were positive, targeted education and planning strategies did not improve providers' and clinical leaders' perceptions of MOUD over time. Strategies that improve leaders' prioritization and support of MOUD and address time constraints related to delivering MOUD may increase access to MOUD in non-substance use treatment clinics.

Family-based treatment for children and adolescents with eating disorders: a mixed-methods evaluation of a blended evidence-based implementation approach

In this study, we evaluated a blended implementation approach with teams learning to provide family-based treatment (FBT) to adolescents with eating disorders. Four sites participated in a sequential mixed method pre-post study to evaluate the implementation of FBT in their clinical settings. The implementation approach included: (a) preparatory site visits; (b) the establishment of implementation teams; (c) a training workshop; (d) monthly clinical consultation; (e) monthly implementation consultation; and (f) fidelity assessment. Quantitative measures examining attitudes toward evidence-based practice, organizational learning environment and organizational readiness for change, as well as, individual readiness for change were delivered pre- and postimplementation. Correlational analyses were used to examine associations between baseline variables and therapist fidelity to FBT. Fundamental qualitative description guided the sampling and data collection for the qualitative interviews performed at the conclusion of the study. Seventeen individuals participated in this study (nine therapists, four medical practitioners, and four administrators). The predetermined threshold of implementation success of 80% fidelity in every FBT session was achieved by only one therapist. However, mean fidelity scores were similar to those reported in other studies. Participant attitudes, readiness, and self-efficacy were not associated with fidelity and did not change significantly from pre- to postimplementation. In qualitative interviews, all participants reported that the implementation intervention was helpful in adopting FBT. Our blended implementation approach was well received by participants. A larger trial is needed to determine which implementation factors predict FBT fidelity and impact patient outcomes.

Fluctuations in barriers to medication treatment for opioid use disorder prescribing over the course of a one-year external facilitation intervention

Background

The Veterans Health Administration (VHA) is invested in expanding access to medication treatment for opioid use disorder (MOUD) to save lives. Access varies across VHA facilities and, thus, requires implementation strategies to promote system-wide adoption of MOUD. We conducted a 12-month study employing external facilitation that targeted MOUD treatment among low-adopting VHA facilities. In this study, we sought to evaluate the patterns of perceived barriers over 1 year of external implementation facilitation using the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework.

Methods

We randomly selected eight VHA facilities from the bottom quartile of the proportion of Veterans with an OUD diagnosis receiving MOUD (< 21%). The 1-year external implementation intervention included developmental evaluation to tailor the facilitation, an on-site visit, and monthly facilitation calls. Facilitators recorded detailed notes for each call on a structured template. Qualitative data was analyzed by coding and mapping barriers to the constructs in the i-PARIHS framework (Innovation, Recipients, Context). We identified emerging themes within each construct by month.

Results

Barriers related to the Innovation, such as provider perception of the need for MOUD in their setting, were minimal throughout the 12-month study. Barriers related to Recipients were predominant and fluctuated over time. Recipient barriers were common during the initial months when providers did not have the training and waivers necessary to prescribe MOUD. Once additional providers (Recipients) were trained and waivered to prescribe MOUD, Recipient barriers dropped and then resurfaced as the facilities worked to expand MOUD prescribing to other clinics. Context barriers, such as restrictions on which clinics could prescribe MOUD and fragmented communication across clinics regarding the management of patients receiving MOUD, emerged more prominently in the middle of the study.

Conclusions

VHA facilities participating in 12-month external facilitation interventions experienced fluctuations in barriers to MOUD prescribing with contextual barriers emerging after a facilitated reduction in recipient- level barriers. Adoption of MOUD prescribing in low-adopting VHA facilities requires continual reassessment, monitoring, and readjustment of implementation strategies over time to meet challenges. Although i-PARIHS was useful in categorizing most barriers, the lack of conceptual clarity was a concern for some constructs.

Disparities in Access to Medications for Opioid Use Disorder in the Veterans Health Administration

OBJECTIVES

A variety of patients - including women, older, racial/ethnic minority, rural, homeless, and justice-involved patients - are vulnerable to experiencing poor healthcare access and quality, such as lower quality substance use disorder treatment, than other populations. The current study examined receipt of medications for opioid use disorder by vulnerable populations within Veterans Health Administration (VHA) facilities to determine whether there are patient and facility factors that are associated with disparities in care.

METHODS

Using national VHA clinical/administrative data from Fiscal Year 2017, we calculated receipt of medications for opioid use disorder using the American Society for Addiction Medicine quality measure specifications. A mixed-effects logistic regression model tested whether patient vulnerability (ie, women, older age, racial/ethnic minority, rural residence, homeless, and justice-involved) and facility (eg, regional location, availability of a methadone clinic) characteristics were associated with medication receipt.

RESULTS

Among the 53,568 veterans at VHA facilities diagnosed with opioid use disorder in Fiscal Year 2017, vulnerable populations - including women, older, Black, rural, homeless, and justice-involved veterans - had lower odds of receiving medications for opioid use disorder than their nonvulnerable counterparts. Veterans had higher odds of receiving medications at facilities with a higher proportion of patients with opioid use disorder, but lower odds of receiving medications at facilities in the Southern region compared to the Northeast region of the United States.

CONCLUSIONS

Quality improvement efforts targeted at vulnerable populations are needed at the VHA to ensure these groups receive the same quality of substance use disorder treatment as other veterans.

Switching pharmacies leads to gaps in medication possession in individuals treated with buprenorphine

BACKGROUND

Not all pharmacies stock and dispense buprenorphine, potentially complicating continuous access to care for patients with opioid use disorder (OUD). This may become problematic if a patient's primary pharmacy can no longer provide buprenorphine, and the patient cannot locate a new pharmacy.

OBJECTIVES

To identify how often patients treated with buprenorphine for OUD switch pharmacies and to estimate the association between switching pharmacies and a clinically significant gap in therapy of 7 days or longer.

METHODS

A retrospective repeated measures longitudinal cohort design was used. Patients initiating treatment with a buprenorphine product indicated for OUD were identified from the 2016-2018 Texas Prescription Monitoring Program. The predictor of interest-switching pharmacies-was defined by comparing the dispensaries used between subsequent prescriptions. The outcome of interest was defined as a gap in medication possession of 7 days or longer on the basis of the National Quality Forum's definition of continuity of pharmacotherapy for OUD. A generalized estimating equation approach was used to estimate a repeated measures logistic regression measuring the association between switching pharmacies and a gap in therapy.

RESULTS

Of 13,375 eligible patients, 29.6% switched pharmacies at least once during treatment, and 51.6% of these did so more than once. The median time to initial switch was 30 days (interquartile range: 13-66 days). When patients switched pharmacies, they were significantly more likely to have a gap in therapy of between 7 and 29 days (adjusted odds ratio 1.67 [95% CI 1.57-1.78]).

CONCLUSION

Patients receiving buprenorphine switch pharmacies early and frequently in treatment, which leads to clinically significant gaps in therapy. Although qualitative explanatory work is needed to understand why patients switch pharmacies so often, pharmacists and prescribers must ensure that patients have reliable access to a convenient source of buprenorphine to prevent gaps in therapy.

"We'll be able to take care of ourselves" - A qualitative study of client attitudes toward implementing buprenorphine treatment at syringe services programs

BACKGROUND

Syringe services programs (SSPs) complement substance use disorder treatment in providing services that improve the health of people who use drugs (PWUD). Buprenorphine treatment is an effective underutilized opioid use disorder treatment. Regulations allow buprenorphine prescribing from office-based settings, potentially including SSPs although few studies have examined this approach. Our objective was to assess the attitudes among PWUD toward the potential introduction of buprenorphine treatment in an SSP. Methods: In this qualitative study, we recruited 34 participants who were enrolled at a New York City-based SSP to participate in one of seven focus group sessions. The focus group facilitators prompted participants to share their thoughts in five domains: attitudes toward (1) medical clinics; (2) harm reduction in general; (3) SSP-based buprenorphine treatment; (4) potential challenges of SSP-based treatment; and (5) logistical considerations of an SSP-based buprenorphine treatment program. Four researchers analyzed focus group transcripts using thematic analysis. Results: Of the 34 participants, most were white (68%), over the age of 40 years old (56%), and had previously tried buprenorphine (89%). Common themes were: 1) The SSP is a supportive community for people who use drugs; 2) Participants felt less stigmatized at the SSP than in general medical settings; 3) Offering buprenorphine treatment could change the SSP's culture; and 4) SSP participants receiving buprenorphine may be tempted to divert their medication. Participants offered suggestions for a slow intentional introduction of buprenorphine treatment at the SSP including structured appointments, training medical providers in harm reduction, and program eligibility criteria. Conclusion: Overall, participants expressed enthusiasm for onsite buprenorphine treatment at SSPs. Research on SSP-based buprenorphine treatment should investigate standard buprenorphine treatment outcomes but also any effects on the program itself and medication diversion. Implementation should consider cultural and environmental aspects of the SSP and consult program staff and participants.

A conceptual model to guide research on the activities and effects of innovation champions

Background

The importance of having a champion to promote implementation efforts has been discussed in the literature for more than five decades. However, the empirical literature on champions remains underdeveloped. As a result, health organizations commonly use champions in their implementation efforts without the benefit of evidence to guide decisions about how to identify, prepare, and evaluate their champions. The goal of this article is to present a model of champion impact that draws upon previous literature and is intended to inform future research on champions and serve as a guide for practitioners serving in a champion role.

Methods

The proposed model is informed by existing literature, both conceptual and empirical. Prior studies and reviews of the literature have faced challenges in terms of operationalizing and reporting on champion characteristics, activities, and impacts. The proposed model addresses this challenge by delineating these constructs, which allows for consolidation of factors previously discussed about champions as well as new hypothesized relationships between constructs.

Results

The model proposes that a combination of champion commitment and champion experience and self-efficacy influence champion performance, which influences peer engagement with the champion, which ultimately influences the champion's impact. Two additional constructs have indirect effects on champion impact. Champion beliefs about the innovation and organizational support for the champion affect champion commitment.

Conclusion

The proposed model is intended to support prospective studies of champions by hypothesizing relationships between constructs identified in the champion literature, specifically relationships between modifiable factors that influence a champion's potential impact. Over time, the model should be modified, as appropriate, based on new findings from champion-related research.

Early impacts of a multi-faceted implementation strategy to increase use of medication treatments for opioid use disorder in the Veterans Health Administration

BACKGROUND

Despite the risk of negative sequelae from opioid use disorder (OUD) and clinical guidelines for the use of effective medication treatment for OUD (M-OUD), many Veterans Health Administration (VHA) providers and facilities lag in providing M-OUD. An intensive external facilitation intervention may enhance uptake in low-adopting VHA facilities by engaging stakeholders from multiple clinical settings within a facility (e.g., mental health, primary care, pain specialty clinic, substance use disorder clinics). Our study identified pre-intervention determinants of implementation through qualitative interviews, described strategies employed during the first 6 months of intensive external facilitation, and explored patterns of implementation determinants in relation to early outcomes.

METHODS

Guided by the integrated-Promoting Action on Research Implementation in Health Services (i-PARIHS) framework, we interviewed stakeholders at low-adopting VHA facilities prior to external facilitation, employed a rapid qualitative analytic process, presented findings during facility visits, and collaboratively created facilitation action plans to achieve goals set by the facilities that would increase M-OUD uptake. The primary outcome was the Substance Use Disorder (SUD)-16, which is a VHA facility-level performance metric consisting of the percent of patients receiving M-OUD among those with an OUD diagnosis. We examined the relationship between pre-implementation factors and 6-month SUD-16 outcomes.

RESULTS

Across eight VHA facilities, we interviewed 68 participants. Implementation determinants included barriers and facilitators across innovation, context, and recipients constructs of i-PARIHS. Each facility selected goals based on the qualitative results. At 6 months, two facilities achieved most goals and two facilities demonstrated progress. The SUD-16 from baseline to 6 months significantly improved in two facilities (8.4% increase (95 % confidence interval [CI] 4.4-12.4) and 9.9% increase (95% CI 3.6-16.2), respectively). Six-month implementation outcomes showed that the extent to which M-OUD aligns with existing clinical practices and values was a primary factor at all facilities, with six of eight facilities perceiving it as both a barrier and facilitator. External health system barriers were most challenging for facilities with the smallest change in SUD-16.

CONCLUSIONS

Early impacts of a multi-faceted implementation approach demonstrated a strong signal for positively impacting M-OUD prescribing in low-adopting VHA facilities. This signal indicates that external facilitation can influence adoption of M-OUD at the facility level in the early implementation phase. These short-term wins experienced by stakeholders may encourage continued adoption and long-term sustainability M-OUD.

Causes of death among U.S. Veterans with a prior nonfatal opioid overdose

BACKGROUND

For over a decade, there has been a surge in opioid-related morbidity and mortality among Veterans. To better understand the impact of the growing epidemic, it is important to identify the cause-specific mortality rates among Veterans with a prior nonfatal opioid overdose.

METHODS

We followed 8370 Veterans who received medical care for a nonfatal opioid overdose between 2011 through 2015.Mortality records were linked to clinical records from the Veterans Health Administration (VHA). We compared the mortality rates among those with a nonfatal opioid overdose to a 5 % stratified random sample of patients accessing services during the same time period. SMRs were calculated using age-adjusted cause-specific mortality rates for the l U.S. population obtained from the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER).

RESULTS

The crude mortality for Veterans with a history of a nonfatal overdose was 370.6 per 10,000 person years. Those with a prior nonfatal overdose had a higher risk of substance-related mortality (aHR [adjusted Hazard Ratio] 5.0), including a higher risk of death from drugs (aHR 6.9) and alcohol (aHR 2.7). Similarly, cause-specific mortalities assessed between Veterans and the U.S. population, SMRs were also highest for deaths associated with substances (114.0).

CONCLUSION

Veterans with a prior nonfatal overdose experienced substantially higher mortality rates compared to other Veterans or the general U.S.

POPULATION

Causes of death related to substance use and mental health were significantly higher than other causes of death, highlighting the importance of integrated treatment and substance use services.

Development and implementation of a physician-pharmacist collaborative practice model for provision and management of buprenorphine/naloxone

Introduction

Physician-pharmacist collaborative practice models (PPCPM) decrease barriers and increase access to medications for opioid use disorder (MOUD) but are not routine in practice. The purpose of this quality improvement initiative is to develop and implement a PPCPM for management of patients on MOUD with buprenorphine/naloxone to minimize provider burden, expand access to treatment, and enhance overall patient care.

Methods

A PPCPM for management of patients on MOUD with buprenorphine/naloxone was piloted in an outpatient substance use disorder clinic. Approximately 4 hours per week were dedicated to physician-pharmacist collaborative medical appointments for a 5-month trial period. The pharmacist met with the patient first and then staffed the case with the collaborating psychiatrist. Descriptive data from PPCPM appointments was collected and compared to data from psychiatrist-only appointments.

Results

Twenty-five patients were seen over 44 appointments with an estimated 33 hours of psychiatrist time saved. Average initial and end buprenorphine doses, urine drug screen (UDS) results, and mental health (MH) medication interventions were similar between patients seen in PPCPM appointments compared with those seen in psychiatrist-only appointments. Collection of UDS, identification and management of MOUD adherence issues, other service referrals, and medication reconciliation intervention were more frequent in PPCPM appointments.

Discussion

Implementation of a PPCPM allowed for provision of a similar level of care regarding MOUD and MH-related medication management while saving psychiatrist time. Other enhancements to patient care provided through pharmacist intervention included more frequent identification and management of MOUD adherence issues, referral for other services, and medication reconciliation interventions.

Barriers and Facilitators to the Implementation of the Pathways to Comorbidity Care (PCC) Training Package for the Management of Comorbid Mental Disorders in Drug and Alcohol Settings

Background: We have previously reported that the Pathways to Comorbidity Care (PCC) training program for alcohol and other drug (AOD) clinicians improved identification of comorbidity, self-efficacy, and attitudes toward screening and monitoring of comorbidity. We aimed to identify barriers and facilitators of implementation of the PCC training program in drug and alcohol settings. Methods: The PCC training program was implemented across 6 matched sites in Australia as per (1), and 20 clinicians received training. PCC training included seminar presentations, workshops conducted by local "clinical champions," individual clinical supervision, and access to an online information portal. We examined barriers and facilitators of implementation according to the Consolidated Framework for Implementation Research. Results: Barriers included inner setting (e.g., allocated time for learning) and characteristics of individuals (e.g., resistance). Facilitators included intervention characteristics (e.g., credible sources), inner setting (e.g., leadership), and outer setting domains (e.g., patient needs). Clinical champions were identified as an important component of the implementation process. Conclusions: Barriers included limited specific allocated time for learning. A credible clinical supervisor, strong leadership engagement and an active clinical champion were found to be facilitators of the PCC training program.

Intervention Stigma toward Medications for Opioid Use Disorder: A Systematic Review

Medications for opioid use disorder (MOUD) are evidence-based treatments, yet can be controversial among some populations. This study provides a systematic review of prejudice and discrimination toward MOUD, a form of "intervention stigma," or stigma associated with a particular medical treatment. A systematic search strategy was used in PsychInfo and PubMed to identify studies published between 1998 and 2018. Studies that empirically examined stigma toward MOUD were included if the manuscript was of moderate or high quality. Studies were analyzed using thematic synthesis. The search yielded 972 studies, of which 28 were included. Most studies utilized qualitative methods to examine intervention stigma toward methadone or buprenorphine, with one including naltrexone. Studies demonstrated that intervention stigma among healthcare providers was influenced by lack of training and abstinent treatment preferences. Providers equated MOUD with illicit substance use and at times refused to care for MOUD patients. Stigma among peer patients seeking treatment was also influenced by abstinent treatment preferences, and among the general public stigma was influenced by lack of MOUD knowledge. Intervention stigma was also driven at the policy level by high regulation of methadone, which fueled diversion and hindered social functioning among patients. Few studies indicated how to reduce intervention stigma toward MOUD. Intervention stigma affects both provision and perceptions of methadone and buprenorphine, decreasing access and utilization of MOUD. Future research should further develop and test MOUD stigma reduction interventions in a variety of social contexts to improve access to care and reduce patient barriers.

Empowering Psychiatric Mental Health Nurse Practitioners to Expand Treatment Opportunities for Veterans With Opioid Use Disorder

BACKGROUND

Few veterans with opioid use disorder receive effective treatment despite the Veterans Health Administration's efforts to expand treatment by offering buprenorphine, a medication to treat opioid use disorder (MOUD). An insufficient prescribing workforce contributes to the underutilization of buprenorphine; however, nurse practitioners (NPs) can now obtain a waiver to prescribe this medication. This quality improvement project aimed to expand the prescribing workforce by educating psychiatric mental health NPs (PMHNPs) working in an emergency setting at a Veterans Affairs Health Care System about free MOUD training and empowering them to utilize buprenorphine treatment.

METHODS

Eleven PMHNPs were asked for their perception of prescribing buprenorphine. They were asked if they had an MOUD waiver and/or were aware of the free waiver training. The PMHNPs were educated on the importance and process of obtaining the DEA-X waiver, and then a post-intervention discussion was completed to determine if they completed the waiver training.

RESULTS

At baseline, all 11 PMHNPs believed offering MOUD was important, but only three had the waiver to prescribe buprenorphine. After the education, three additional PMHNPs obtained the waiver and 10 planned to have the waiver in the next year. The department is planning to trial offering buprenorphine treatment, and PMHNPs at this facility are privileged to prescribe buprenorphine. In addition, five new PMHNP residents started or completed the training.

CONCLUSIONS

This project shows the potential to increase veteran access to MOUD by emphasizing education and empowering PMHNPs to initiate treatment. Providing education regarding the importance of buprenorphine treatment in the emergency setting and delivering information about the free waiver training facilitated workforce preparedness.

Increasing Access to Medications for Opioid Use Disorder and Complementary and Integrative Health Services in Primary Care

OBJECTIVES

Evidence-based therapies for opioid use disorder (OUD) and chronic pain, such as medications for OUD (MOUD) and complementary and integrative health (CIH; e.g., acupuncture and meditation) therapies, exist. However, their adoption has been slow, particularly in primary care, due to numerous implementation challenges. We sought to expand the use of MOUD and CIH within primary care by using an evidence-based quality improvement (EBQI) implementation strategy.

METHODS

We used EBQI to engage two facilities in the Veterans Health Administration (VHA) from June 2018 to September 2019. EBQI included multilevel stakeholder engagement, with external facilitators providing technical support, practice facilitation, and routine data feedback. We established a quality improvement (QI) team at each facility with diverse stakeholders (e.g., primary care, addiction, pain, nursing, pharmacy). We met monthly with regional stakeholders to address implementation barriers. We also convened an advisory board to ensure alignment with national priorities.

RESULTS

Pre-implementation interviews indicated facility-level and provider-level barriers to prescribing buprenorphine, including strong primary care provider resistance. Both facilities developed action plans. They both conducted educational meetings (e.g., Grand Rounds, MOUD waiver trainings). Facility A also offered clinical preceptorships for newly trained primary care prescribers. Facility B used mass media and mailings to educate patients about MOUD and CIH options and dashboards to identify potential candidates for MOUD. After 15 months, both facilities increased their OUD treatment rates to the ≥ 90th percentile of VHA medical centers nationally. Exit interviews indicated an attitudinal shift in MOUD delivery in primary care. Stakeholders valued the EBQI process, particularly cross-site collaboration.

IMPLICATIONS

Despite initial implementation barriers, we effectively engaged stakeholders using EBQI strategies. Local QI teams used an assortment of QI interventions and developed tools to catapult their facilities to among the highest performers in VHA OUD treatment.

IMPACTS

EBQI is an effective strategy to partner with stakeholders to implement MOUD and CIH therapies.

Barriers and Facilitators to the Use of Medications for Opioid Use Disorder: a Rapid Review

BACKGROUND

Despite evidence that medications to treat opioid use disorder (OUD) are effective, most people who could benefit from this treatment do not receive it. This rapid review synthesizes evidence on current barriers and facilitators to buprenorphine/naloxone and naltrexone at the patient, provider, and system levels to inform future interventions aimed at expanding treatment.

METHODS

We systematically searched numerous bibliographic databases through May 2020 and selected studies published since 2014. Study selection, data abstraction, coding of barriers and facilitators, and quality assessment were first completed by one reviewer and checked by a second.

RESULTS

We included 40 studies of buprenorphine (5 also discussed naltrexone). Four types of patient and provider-level barriers to OUD medication use emerged-stigma related to OUD medications, treatment experiences and beliefs (positive or negative), logistical issues (time and costs as well as insurance and regulatory requirements), and knowledge (high or low) of OUD and the role of medications. Stigma was the most common barrier among patients, while logistical issues were the most common barriers among providers. Facilitators for both patients and providers included peer supports. Most administrator-identified or system-level barriers and facilitators fit into the category of logistical issues. We have moderate confidence in buprenorphine findings but low confidence in naltrexone findings due to the small number of studies.

DISCUSSION

Stigma, treatment experiences, logistical issues, and knowledge gaps are the main barriers associated with low utilization of OUD medications. These barriers can overlap and mutually reinforce each other, but given that, it is plausible that reducing one barrier may lead to reductions in others. The highest priority for future research is to evaluate interventions to reduce stigma. Other priorities for future research include better identification of barriers and facilitators for specific populations, such as those with OUD related to prescription opioids, and for naltrexone use.

A Research Agenda for Advancing Strategies to Improve Opioid Safety: Findings from a VHA State of the Art Conference

US military Veterans have been disproportionately impacted by the US opioid overdose crisis. In the fall of 2019, the Veterans Health Administration (VHA) convened a state-of-the-art (SOTA) conference to develop research priorities for advancing the science and clinical practice of opioid safety, including both use of opioid analgesics and managing opioid use disorder. We present the methods and consensus recommendations from the SOTA. A core group of researchers and VA clinical stakeholders defined three areas of focus for the SOTA: managing opioid use disorder, long-term opioid therapy for pain including consideration for opioid tapering, and treatment of co-occurring pain and substance use disorders. The SOTA participants divided into three workgroups and identified key questions and seminal studies related to those three areas of focus. The strongest recommendations included testing implementation strategies in the VHA for expanding access to medication treatment for opioid use disorder, testing collaborative tapering programs for patients prescribed long-term opioids, and larger trials of behavioral and exercise/movement interventions for pain among patients with substance use disorders.

Organizational Facilitators and Barriers to Medication for Opioid Use Disorder Capacity Expansion and Use

Medication for opioid use disorder (MOUD) is a key strategy for addressing the opioid use disorder crisis, yet gaps in MOUD provision impede this strategy's benefits. The research reported here sought to understand what distinguishes low- and high-performing organizations in building and using capacity to provide MOUD. As part of a mixed methods MOUD implementation trial, semi-structured telephone interviews were conducted with personnel from low- and high-performing MOUD-providing organizations. Seventeen individuals from 17 organizations were interviewed. Findings demonstrate the importance of individual, organization, and community-level factors in supporting the building and use of MOUD capacity. Low- and high-performing organizations showed different patterns of facilitators and barriers during the implementation process. The key difference between low- and high-performing organizations was the level of organizational functioning. A better understanding of an organization's assets and deficits at the individual, organizational, and community levels would allow decision-makers to tailor their approaches to MOUD implementation.

Correlates of Transitions Into Housing Instability Among Veterans Accessing Veterans Health Administration Health Care

BACKGROUND

Prior research has explored the patterns and dynamics of homelessness; such an understanding is necessary to improve policy and programmatic responses and prevent new episodes of housing instability.

OBJECTIVES

The objectives of this study are to identify correlates of veterans' transitions into housing instability and inform initiatives aimed to address their needs, with a focus on how to prevent new episodes of housing instability.

METHODS

The cohort for this study includes 4,633,069 veterans who responded to the Veterans Health Administration's universal screen for housing instability at least twice between October 1, 2012, and September 30, 2016; 1.2% reported recent housing instability and 98.8% reported ongoing housing stability. The χ or Fisher exact tests, as appropriate, compared veterans' characteristics by housing status. A multivariate logistic regression identified independent risk factors associated with recent housing instability, controlling for sociodemographic, military service, diagnostic, and health services use variables.

RESULTS

Sociodemographic and health services use variables increased veterans' odds of transitioning into housing instability. The diagnoses with the greatest effect sizes were drug use disorder (adjusted odds ratio=1.50, 95% confidence interval: 1.45-1.55) and opioid use disorder, which was associated with a >2-fold increase in the odds of experiencing recent housing instability (adjusted odds ratio=2.22, 95% confidence interval: 2.04-2.41).

CONCLUSIONS

The present study provides evidence to inform existing and future interventions to prevent new episodes of housing instability. Veterans with opioid use disorder were at greatest risk of becoming unstably housed; increasing access to medication-assisted treatment in homeless-focused services is needed.

The role of substance use disorders in experiencing a repeat opioid overdose, and substance use treatment patterns among patients with a non-fatal opioid overdose

BACKGROUND

A non-fatal opioid overdose (NFOO) increases the risk of another overdose and identifies high-risk patients. We estimated the risk of repeat opioid overdose for patients with and without substance use disorder (SUD) diagnoses and the change in substance use treatment utilization rates associated with the first NFOO.

METHODS

We selected patients (>18 years of age) from Kaiser Permanente Northern California with a NFOO between 2009-2016 (n = 3,992). Cox proportional hazards models estimated the 1-year risk of opioid overdose associated with SUD diagnoses (opioid, alcohol, cannabis, amphetamine, sedative, and cocaine), controlling for patient characteristics. Among patients with an index NFOO, we calculated monthly utilization rates for outpatient substance use services and buprenorphine before and after the index overdose. Interrupted time series models estimated the change in level and trend in utilization rates associated with the index overdose.

RESULTS

Approximately 7.2 % of patients had a repeat opioid overdose during the year after the index NFOO. The only SUD diagnosis significantly associated with greater risk of repeat overdose was opioid use disorder (OUD) (aHR: 1.51; 95 % CI: 1.13-2.01). Before the index overdose, 4.16 % of patients received outpatient substance use services and 1.32 % received buprenorphine. The index overdose was associated with a 5.94 % (standard error: 0.77 %) absolute increase in outpatient substance use services and a 1.29 % (standard error: 0.15 %) increase in buprenorphine.

CONCLUSION

Patients with a NFOO and OUD are vulnerable to another overdose. Low initiation rates for substance use treatment after a NFOO indicate a need to address patient, provider, and system barriers.

Outcomes of a novel office-based opioid treatment program in an internal medicine resident continuity practice

BACKGROUND

The integration of opioid use disorder (OUD) care and competencies in graduate medical education training is needed. Previous research shows improvements in knowledge, attitudes, and practices after exposure to OUD care. Few studies report outcomes for patients with OUD in resident physician continuity practices.

METHODS

A novel internal office-based opioid treatment (OBOT) program was initiated in a resident continuity clinic. Surveys of resident and staff knowledge and attitudes of OBOT were administered at baseline and 4 months. A retrospective chart review of the 15-month OBOT clinic obtained patient characteristics and outcomes.

RESULTS

Twelve patients with OUD were seen in the OBOT clinic. Seven patients (58%) were retained in care at the end of the study period for a range of 9-15 months. Eight patients demonstrated a good clinical response. Surveys of residents and staff at 4 months were unchanged from baseline showing persistent lack of comfort in caring for patients with OUD.

CONCLUSIONS

OBOT can be successfully integrated into resident continuity practices with positive patient outcomes. Improvement in resident and staff attitudes toward OBOT were not observed and likely require direct and frequent exposure to OUD care to increase acceptance.

Barriers and facilitators to buprenorphine use for opioid agonist treatment: protocol for a scoping review

INTRODUCTION

In the context of the opioid crisis in North America, the benefits of evidence-based opioid agonist treatments such as buprenorphine/naloxone have not been optimised due to low uptake. Numerous factors contribute to the underuse of buprenorphine, and theory-informed approaches to identify and address implementation barriers and facilitators are needed. This scoping review aims to characterise the barriers and facilitators at the patient, healthcare professional, organisation and system level according to the Theoretical Domains Framework (TDF), and identify gaps to inform practice and policy.

METHODS AND ANALYSIS

We will conduct a scoping review using established methods and follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. We will identify English and French-language peer-reviewed literature by searching five electronic bibliographic databases (MEDLINE, Embase, PsychINFO, CINAHL, and SocINDEX), from inception and use Google, websites of key organisations, and two or more custom search engines to identify relevant grey literature. Eligible records will be quantitative or qualitative studies that examine barriers and facilitators to buprenorphine use at the patient, healthcare professional, organisation and system level, and involve participants with diagnosis of opioid use disorder or professionals involved in their care. Two reviewers will be involved in independently screening, reviewing and charting the data and calibration exercises will be conducted at each stage. We will conduct descriptive analysis for the charted data, and deductively code barriers and facilitators using the TDF.

ETHICS AND DISSEMINATION

As a scoping review of the literature, this study does not require ethics approval. Our dissemination strategy will focus on developing tailored activities to meet the needs of diverse knowledge user audiences. Barriers and facilitators mapped to the TDF can be linked to evidence-based strategies for change to improve buprenorphine use and access, and enable practice to reduce opioid-related harms.
