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

Buprenorphine use among non-hospital residential programs

BACKGROUND

The purpose of this study is to investigate the use of buprenorphine within non-hospital residential programs. We hypothesize that programs offering long-term treatment will be less likely to accept or prescribe buprenorphine, but those that accept public insurance will demonstrate relative increased likelihood of buprenorphine availability.

METHOD

This study analyzed data from the 2021 National Substance Use and Mental Health Services Survey. The analytic sample (n=3654) included a subset of facilities that reported providing only substance use treatment, including three non-mutually exclusive service types: detox, short-term, and long-term. A logistic regression examined the association between buprenorphine availability and residential service type, holding constant characteristics associated with the outcome of interest. We then tested an interaction between public insurance and long-term service type on the outcome of interest.

RESULTS

While long-term service type was associated with reduced odds of buprenorphine availability (OR=.288, p <.05), programs that both offered long-term residential programs and accepted public health insurance had 3.5 higher odds of accepting or prescribing buprenorphine (OR=4.586, p<.01) compared to long-term programs without public insurance.

IMPLICATIONS

Patients who require treatment of longer duration may face barriers to buprenorphine availability; however, public insurance acceptance may increase odds of availability of buprenorphine among long-term programs.

Implementation of medication for opioid use disorder treatment during a natural disaster: The PROUD-LA study

BACKGROUND

The impacts of climate change-related extreme weather events (EWEs) on Medication for Opioid Use Disorders (MOUD) implementation for Medicaid beneficiaries are relatively unknown. Such information is critical to disaster planning and other implementation strategies. In this study we examined implementation determinants and strategies for MOUD during EWEs.

METHODS

The Louisiana-based Community Resilience Learning Collaborative and Research Network (C-LEARN) utilized Rapid Assessment Procedures-Informed Community Ethnography (RAPICE), involving community leaders in study design, execution, and data analysis. We conducted qualitative semi-structured interviews with 42 individuals, including MOUD Medicaid member patients and their caregivers, healthcare providers and administrators, and public health officials with experience with climate-related disasters. We mapped key themes onto updated Consolidated Framework for Implementation Research domains.

RESULTS

MOUD use is limited during EWEs by pharmacy closures, challenges to medication prescription and access across state lines, hospital and clinic service limits, overcrowded emergency departments, and disrupted communications with providers. MOUD demand simultaneously increases due to the stress associated with displacement, resource loss, the COVID-19 pandemic, and social determinants of health. Effective implementation strategies include healthcare system disaster plans with protocols for clear and regular patient-provider communication, community outreach, additional staffing, and virtual delivery of services. Providers can also increase MOUD access by having remote access to EHRs, laptops and contact information, resource lists, collaborative networks, and contact with patients via call centers and social media. Patients can retain access to MOUD via online patient portals, health apps, call centers, and provider calls and texts. The impact of EWEs on MOUD access and use is also influenced by individual characteristics of both patients and providers.

CONCLUSIONS

The increasing frequency and severity of climate-related EWEs poses a serious threat to MOUD for Medicaid beneficiaries. MOUD-specific disaster planning and use of telehealth for maintaining contact and providing care are effective strategies for MOUD implementation during EWEs. Potential considerations for policies and practices of Medicaid, providers, and others to benefit members during hurricanes or major community stressors, include changes in Medicaid policies to enable access to MOUD by interstate evacuees, improvement of medication refill flexibilities, and incentivization of telehealth services for more systematic use.

Integrating Buprenorphine for Opioid Use Disorder into Rural, Primary Care Settings

BACKGROUND

Medications for opioid use disorder (MOUD) including buprenorphine are effective, but underutilized. Rural patients experience pronounced disparities in access. To reach rural patients, the US Department of Veterans Affairs (VA) has sought to expand buprenorphine prescribing beyond specialty settings and into primary care.

OBJECTIVE

Although challenges remain, some rural VA health care systems have begun offering opioid use disorder (OUD) treatment with buprenorphine in primary care. We conducted interviews with clinicians, leaders, and staff within these systems to understand how this outcome had been achieved.

DESIGN

Using administrative data from the VA Corporate Data Warehouse (CDW), we identified rural VA health care systems that had improved their rate of primary care-based buprenorphine prescribing over the period 2015-2020. We conducted qualitative interviews (n = 30) with staff involved in implementing or prescribing buprenorphine in these systems to understand the processes that had facilitated implementation.

PARTICIPANTS

Clinicians, staff, and leaders embedded within rural VA health care systems located in the Northwest, West, Midwest (2), South, and Northeast.

APPROACH

Qualitative interviews were analyzed using a mixed inductive/deductive approach.

KEY RESULTS

Interviews revealed the processes through which buprenorphine was integrated into primary care, as well as processes insufficient to enact change. Implementation was often initially catalyzed through a targeted hire. Champions then engaged clinicians and leaders one-on-one to "pitch" the case, describe concordance between buprenorphine prescribing and existing goals, and delineate the supportive role that they could provide. Sites were prepared for implementation by developing new clinical teams and redesigning clinical processes. Each of these processes was made possible with the active, instrumental support of leadership.

CONCLUSIONS

Results suggest that rural systems seeking to improve buprenorphine accessibility in primary care may need to alter primary care structures to accommodate buprenorphine prescribing, whether through new hires, team development, or clinical redesign.

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.

Integrating Opioid Use Disorder Treatment Into Primary Care Settings

Importance

Medication for opioid use disorder (MOUD) (eg, buprenorphine and naltrexone) can be offered in primary care, but barriers to implementation exist.

Objective

To evaluate an implementation intervention over 2 years to explore experiences and perspectives of multidisciplinary primary care (PC) teams initiating or expanding MOUD.

Design, Setting, and Participants

This survey-based and ethnographic qualitative study was conducted at 12 geographically and structurally diverse primary care clinics that enrolled in a hybrid effectiveness-implementation study from July 2020 to July 2022 and included PC teams (prescribing clinicians, nonprescribing behavioral health care managers, and consulting psychiatrists). Survey data analysis was conducted from February to April 2022.

Exposure

Implementation intervention (external practice facilitation) to integrate OUD treatment alongside existing collaborative care for mental health services.

Measures

Data included (1) quantitative surveys of primary care teams that were analyzed descriptively and triangulated with qualitative results and (2) qualitative field notes from ethnographic observation of clinic implementation meetings analyzed using rapid assessment methods.

Results

Sixty-two primary care team members completed the survey (41 female individuals [66%]; 1 [2%] American Indian or Alaskan Native, 4 [7%] Asian, 5 [8%] Black or African American, 5 [8%] Hispanic or Latino, 1 [2%] Native Hawaiian or Other Pacific Islander, and 46 [4%] White individuals), of whom 37 (60%) were between age 25 and 44 years. An analysis of implementation meetings (n = 362) and survey data identified 4 themes describing multilevel factors associated with PC team provision of MOUD during implementation, with variation in their experience across clinics. Themes characterized challenges with clinical administrative logistics that limited the capacity to provide rapid access to care and patient engagement as well as clinician confidence to discuss aspects of MOUD care with patients. These challenges were associated with conflicting attitudes among PC teams toward expanding MOUD care.

Conclusions and Relevance

The results of this survey and qualitative study of PC team perspectives suggest that PC teams need flexibility in appointment scheduling and the capacity to effectively engage patients with OUD as well as ongoing training to maintain clinician confidence in the face of evolving opioid-related clinical issues. Future work should address structural challenges associated with workload burden and limited schedule flexibility that hinder MOUD expansion in PC settings.

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.

Access to Medications for Opioid Use Disorder in Rural Versus Urban Veterans Health Administration Facilities

BACKGROUND

For patients with opioid use disorder (OUD), medications for OUD (MOUD) reduce morbidity, mortality, and return to use. Nevertheless, a minority of patients receive MOUD, and underutilization is pronounced among rural patients.

OBJECTIVE

While Veterans Health Administration (VHA) initiatives have improved MOUD access overall, it is unknown whether access has improved in rural VA health systems specifically. How "Community Care," healthcare paid for by VHA but received from non-VA providers, has affected rural access is also unknown.

DESIGN

Data for this observational study were drawn from the VHA Corporate Data Warehouse. Facility rurality was defined by rural-urban commuting area code of the primary medical center. International Classification of Diseases codes identified patients with OUD within each year, 2015-2020. We included MOUD (buprenorphine, methadone, extended-release naltrexone) received from VHA or paid for by VHA but received at non-VA facilities through Community Care. We calculated average yearly MOUD receipt; linear regression of outcomes on study years identified trends; an interaction between year and rural status evaluated trend differences over time.

PARTICIPANTS

All 129 VHA Health Systems, a designation that encompasses one or more medical centers and their affiliated community-based outpatient clinics MAIN MEASURES: The average proportion of patients diagnosed with OUD that receive MOUD within rural versus urban VHA health care systems.

KEY RESULTS

From 2015 to 2020, MOUD access increased substantially: the average proportion of patients receiving MOUD increased from 34.6 to 48.9%, with a similar proportion of patients treated with MOUD in rural and urban systems in all years. Overall, a small proportion (1.8%) of MOUD was provided via Community Care, and Community Care did not disproportionately benefit rural health systems.

CONCLUSIONS

Strategies utilized by VHA could inform other health care systems seeking to ensure that, regardless of geographic location, all patients are able to access MOUD.

Iteration is not solving the opioid crisis, it's time for transformation

Opioid use disorder (OUD) produces exceedingly high rates of morbidity and mortality in the United States and throughout the world. Almost 90% of persons qualifying for treatment do not enter treatment and 72% of those who initiate treatment leave within 60 days. This Perspective posits that over the past decade our OUD treatment system has produced only small iterative gains in treatment access because, in part, it is founded in a series of top-down regulatory policies dating back more than 100 years. These policies prioritized restricting persons with OUD from having access to opioid agonists over empirical discovery of treatment best practice. It further suggests that for persons who are not already responding positively to our existing treatments, we may need to fundamentally transform care to enact true, meaningful change. Four potential considerations are outlined: expanding beyond long-acting opioids for treatment, embracing safe use as a viable therapeutic target, ending closed medication distribution systems, and partnering with our patients. The overarching aim of this discussion is to motivate broader thinking about new solutions for the patients for whom the existing strategies are not working and who may benefit from more transformative approaches. Though efforts to-date to expand existing treatment systems and find new ways to promote existing MOUDs have been important, these efforts have represented iterative changes. For us to meet our goal of substantially reducing opioid-related harms, it may be time to consider strategies that represent true transformation.

Characterization of Unintentional Deaths Among Buprenorphine Users

OBJECTIVE

Medications used to treat opioid use disorder (OUD) reduce drug overdose risk. Buprenorphine is often the preferred treatment for OUD because of its high safety profile. Given expanding buprenorphine use, this study sought to examine buprenorphine-involved deaths (BIDs) and compare them with other drug-related deaths.

METHOD

West Virginia drug-related deaths from 2005 to early 2020 were identified. Study data included decedent demographics, toxicology, autopsy findings, and medical and prescription histories. Characteristics of BIDs compared with other drug-related deaths were statistically analyzed.

RESULTS

Among 11,764 drug-related deaths, only 564 (4.8%) involved buprenorphine. Buprenorphine alone was present in 32 deaths, of which 20 were considered the direct cause of death (0.2% of all drug-related deaths). Significantly more BIDs involved five or more drugs (23%) compared with other opioid deaths (14.9%). Co-intoxicants found most frequently in BIDs were benzodiazepines (47.3%), methamphetamine (27.1%), and fentanyl (22.9%). Cardiovascular and pulmonary comorbidities were identified in 43% and 21% of BIDs, respectively. Of the 564 BIDs, a current buprenorphine prescription was present in 132 deaths (23.4%).

CONCLUSIONS

Despite increasing buprenorphine use, BIDs comprised less than 5% of overall West Virginia drug-related deaths. Seldom was it the only drug found, and most decedents did not have current prescriptions for buprenorphine. Although buprenorphine is effective, with a wide safety margin, clinicians and patients should be aware that buprenorphine can be involved in overdose deaths, especially when buprenorphine is taken in combination with drugs such as benzodiazepines, methamphetamine, or fentanyl, and in persons with underlying cardiovascular or pulmonary comorbidities.

"I'm Clean and Sober, But Not Necessarily Free": Perceptions of Buprenorphine Among Patients in Long-Term Treatment

BACKGROUND

Patients receiving buprenorphine for the treatment of opioid use disorder (OUD) experience a roughly 50% reduction in mortality risk relative to those not receiving medication. Longer periods of treatment are also associated with improved clinical outcomes. Despite this, patients often express desires to discontinue treatment and some view taper as treatment success. Little is known about the beliefs and medication perspectives of patients engaged in long-term buprenorphine treatment that may underlie motivations to discontinue.

METHODS

This study was conducted at the VA Portland Health Care System (2019-2020). Qualitative interviews were conducted with participants prescribed buprenorphine for ≥2 years. Coding and analysis were guided by directed qualitative content analysis.

RESULTS

Fourteen patients engaged in office-based buprenorphine treatment completed interviews. While patients expressed strong enthusiasm for buprenorphine as a medication, the majority expressed the desire to discontinue, including patients actively tapering. Motivations to discontinue fell into 4 categories. First, patients were troubled by perceived side effects of the medication, including effects on sleep, emotion, and memory. Second, patients expressed unhappiness with being "dependent" on buprenorphine, framed in opposition to personal strength/independence. Third, patients expressed stigmatized beliefs about buprenorphine, describing it as "illicit," and associated with past drug use. Finally, patients expressed fears about buprenorphine unknowns, including potential long-term health effects and interactions with medications required for surgery.

CONCLUSIONS

Despite recognizing benefits, many patients engaged in long-term buprenorphine treatment express a desire to discontinue. Findings from this study may help clinicians anticipate patient concerns and can be used to inform shared decision-making conversations regarding buprenorphine treatment duration.
