Medications for opioid use disorder in the Department of Veterans Affairs (VA) health care system: Historical perspective, lessons learned, and next steps

Trends in Opioid Use Disorder in the Veterans Health Administration, 2005-2022

Importance

Given the personal and social burdens of opioid use disorder (OUD), understanding time trends in OUD prevalence in large patient populations is key to planning prevention and treatment services.

Objective

To examine trends in the prevalence of OUD from 2005 to 2022 overall and by age, sex, and race and ethnicity.

Design, Setting, and Participants

This serial cross-sectional study included national Veterans Health Administration (VHA) electronic medical record data from the VHA Corporate Data Warehouse. Adult patients (age ≥18 years) with a current OUD diagnosis (using International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] and International Statistical Classification of Diseases, Tenth Revision, Clinical Modification [ICD-10-CM] codes) who received outpatient care at VHA facilities from January 1, 2005, to December 31, 2022, were eligible for inclusion in the analysis.

Main Outcomes and Measures

The main outcome was OUD diagnoses. To test for changes in prevalence of OUD over time, multivariable logistic regression models were run that included categorical study year and were adjusted for sex, race and ethnicity, and categorical age.

Results

The final sample size ranged from 4 332 165 to 5 962 564 per year; most were men (89.3%-95.0%). Overall, the annual percentage of VHA patients diagnosed with OUD almost doubled from 2005 to 2017 (0.60% [95% CI, 0.60%-0.61%] to 1.16% [95% CI, 1.15%-1.17%]; adjusted difference, 0.55 [95% CI, 0.54-0.57] percentage points) and declined thereafter (2022: 0.97% [95% CI, 0.97%-0.98%]; adjusted difference from 2017 to 2022, -0.18 [95% CI, -0.19 to -0.17] percentage points). This trend was similar among men (0.64% [95% CI, 0.63%-0.64%] in 2005 vs 1.22% [95% CI, 1.21%-1.23%] in 2017 vs 1.03% [95% CI, 1.02%-1.04%] in 2022), women (0.34% [95% CI, 0.32%-0.36%] in 2005 vs 0.68% [95% CI, 0.66%-0.69%] in 2017 vs 0.53% [95% CI, 0.52%-0.55%] in 2022), those younger than 35 years (0.62% [95% CI, 0.59%-0.66%] in 2005 vs 2.22% [95% CI, 2.18%-2.26%] in 2017 vs 1.00% [95% CI, 0.97%-1.03%] in 2022), those aged 35 to 64 years (1.21% [95% CI, 1.19%-1.22%] in 2005 vs 1.80% [95% CI, 1.78%-1.82%] in 2017 vs 1.41% [95% CI, 1.39%-1.42%] in 2022), and non-Hispanic White patients (0.44% [95% CI, 0.43%-0.45%] in 2005 vs 1.28% [95% CI, 1.27%-1.29%] in 2017 vs 1.13% [95% CI, 1.11%-1.14%] in 2022). Among VHA patients aged 65 years or older, OUD diagnoses increased from 2005 to 2022 (0.06% [95% CI, 0.06%-0.06%] to 0.61% [95% CI, 0.60%-0.62%]), whereas among Hispanic or Latino and non-Hispanic Black patients, OUD diagnoses decreased from 2005 (0.93% [95% CI, 0.88%-0.97%] and 1.26% [95% CI, 1.23%-1.28%], respectively) to 2022 (0.61% [95% CI, 0.59%-0.63%] and 0.82% [95% CI, 0.80%-0.83%], respectively).

Conclusions and Relevance

This serial cross-sectional study of national VHA electronic health record data found that the prevalence of OUD diagnoses increased from 2005 to 2017, peaked in 2017, and declined thereafter, a trend primarily attributable to changes among non-Hispanic White patients and those younger than 65 years. Continued public health efforts aimed at recognizing, treating, and preventing OUD are warranted.

Pain, Substance Use Disorders, Mental Health, and Buprenorphine Treatment among Patients With and Without HIV

Treatment of opioid use disorder (OUD) with buprenorphine improves outcomes and mortality among people with HIV (PWH). However, engagement is low and is influenced by comorbidities. We examined the impact of patterns of co-occurring pain, substance use disorders (SUDs), and mental health diagnoses on buprenorphine initiation and retention in PWH. The Veterans Aging Cohort Study contained 7,875 patients (2,702 PWH and 5,173 without HIV) with new OUD clinical encounters (2008-2017). Buprenorphine initiation and retention were derived from prescription data. We identified patterns of co-occurring diagnoses (via ICD codes) and assessed the effects of class membership on both outcomes using latent class analysis and regression analyses. The mean age of patients was 55, 98% were male, 58% Black, 8% Hispanic, and only 8% initiated buprenorphine within 12 months of OUD diagnosis. Four classes of co-occurring diagnoses were identified: "Few Co-occurring Diagnoses" (42.3%); "Multiple Pain Conditions" (21.3%); "Pain + SUD" (18.4%) and "Pain + SUD + Mental Health" (18.0%). Patients in the "Pain + SUD" class and "Pain + SUD + Mental Health" class were significantly less likely to initiate buprenorphine and had 59% and 45% lower odds, respectively, of initiating buprenorphine compared with patients in the "Few Co-occurring Diagnoses" class; this effect did not vary by HIV status. Buprenorphine retention was not significantly associated with HIV status or class membership. However, Black Veterans were less likely to initiate or be retained in buprenorphine treatment. Higher comorbidity burden was negatively associated with buprenorphine initiation but not with retention. More research is warranted to determine other factors that may influence treatment retention.

Improving access to buprenorphine for rural veterans in a learning health care system

OBJECTIVE

To describe a learning health care system research process designed to increase buprenorphine prescribing for the treatment of opioid use disorder (OUD) in rural primary care settings within U.S. Department of Veterans Affairs (VA) treatment facilities.

DATA SOURCES AND STUDY SETTING

Using national administrative data from the VA Corporate Data Warehouse, we identified six rural VA health care systems that had improved their rate of buprenorphine prescribing within primary care from 2015 to 2020 (positive deviants). We conducted qualitative interviews with leaders, clinicians, and staff involved in buprenorphine prescribing within primary care from these sites to inform the design of an implementation strategy.

STUDY DESIGN

Qualitative interviews to inform implementation strategy development.

DATA COLLECTION/EXTRACTION METHODS

Interviews were audio-recorded, transcribed verbatim, and coded by a primary coder and secondary reviewer. Analysis utilized a mixed inductive/deductive approach. To develop an implementation strategy, we matched clinical needs identified within interviews with resources and strategies participants had utilized to address these needs in their own sites.

PRINCIPAL FINDINGS

Interview participants (n = 30) identified key clinical needs and strategies for implementing buprenorphine in rural, primary care settings. Common suggestions included the need for clinical mentorship or a consult service, buprenorphine training, and educational resources. Building upon interview findings and in partnership with a clinical team, we developed an implementation strategy composed of an engaging case-based training, an audit and feedback process, and educational resources (e.g., Buprenorphine Frequently Asked Questions, Rural Care Model Infographic).

CONCLUSIONS

We describe a learning health care system research process that leveraged national administrative data, health care provider interviews, and clinical partnership to develop an implementation strategy to encourage buprenorphine prescribing in rural primary care settings.

Engaging healthcare teams to increase access to medications for opioid use disorder

OBJECTIVE

To assess the effectiveness of evidence-based quality improvement (EBQI) as an implementation strategy to expand the use of medications for opioid use disorder (MOUD) within nonspecialty settings.

DATA SOURCES AND STUDY SETTING

We studied eight facilities in one Veteran Health Administration (VHA) region from October 2015 to September 2022 using administrative data.

STUDY DESIGN

Initially a pilot, we sequentially engaged seven of eight facilities from April 2018 to September 2022 using EBQI, consisting of multilevel stakeholder engagement, technical support, practice facilitation, and data feedback. We established facility-level interdisciplinary quality improvement (QI) teams and a regional-level cross-facility collaborative. We used a nonrandomized stepped wedge design with repeated cross sections to accommodate the phased implementation. Using aggregate facility-level data from October 2015 to September 2022, we analyzed changes in patients receiving MOUD using hierarchical multiple logistic regression.

DATA COLLECTION/EXTRACTION METHODS

Eligible patients had an opioid use disorder (OUD) diagnosis from an outpatient or inpatient visit in the previous year. Receiving MOUD was defined as having been prescribed an opioid agonist or antagonist treatment or a visit to an opioid substitution clinic.

PRINCIPAL FINDINGS

The probability of patients with OUD receiving MOUD improved significantly over time for all eight facilities (average marginal effect [AME]: 0.0057, 95% CI: 0.0044, 0.0070) due to ongoing VHA initiatives, with the probability of receiving MOUD increasing by 0.577 percentage points, on average, each quarter, totaling 16 percentage points during the evaluation period. The seven facilities engaging in EBQI experienced, on average, an additional 5.25 percentage point increase in the probability of receiving MOUD (AME: 0.0525, 95%CI: 0.0280, 0.0769). EBQI duration was not associated with changes.

CONCLUSIONS

EBQI was effective for expanding access to MOUD in nonspecialty settings, resulting in increases in patients receiving MOUD exceeding those associated with temporal trends. Additional research is needed due to recent MOUD expansion legislation.

Are gaps in rates of retention on buprenorphine for treatment of opioid use disorder closing among veterans across different races and ethnicities? A retrospective cohort study

INTRODUCTION

The U.S. Veterans Health Administration has undertaken several initiatives to improve veterans' access to and retention on buprenorphine because it prevents overdose and reduces drug-related morbidity. We aimed to determine whether improvements in retention duration over time was equitable across veterans of different races and ethnicities.

METHODS

This retrospective cohort study was conducted among veterans who initiated buprenorphine from federal fiscal years (FY) 2006 to 2020 after diagnosis of opioid use disorder. Using an accelerated failure time model, we estimated the association between time to buprenorphine discontinuation and FY of initiation, race and ethnicity, and other control covariates. We followed veterans from buprenorphine initiation until they discontinued or had a censoring event. We then estimated the predicted median days retained on buprenorphine, the average marginal effect of initiating in a later FY, the same measure by race and ethnicity, the incremental effect of the various racial and ethnic identities in contrast to non-Hispanic White, and the total change in the size of the gap over the 15 years of the study between veterans with a minoritized racial or ethnic identity compared to non-Hispanic White veterans.

RESULTS

Most of the 31,797 veterans in the sample were non-Hispanic White (74.5 %), from urban areas (83.5 %), male (92.0 %), and had significant comorbidities, most frequently anxiety disorders (51.0 %) and depression (63.0 %). Overall, 49.8 % of veterans were retained at least 180 days. The average marginal effect of FY was 7.0 days [95%CI:5.3, 8.8] but was significantly smaller among veterans identifying as Black or African American [3.2 days; 95%CI:2.4, 4.1] or Asian [3.6 days; 95%CI:1.6, 5.7] compared to veterans who identify as non-Hispanic White [7.9 days; 95%CI:5.9, 9.9]. Additional measures of change were significant for veterans identifying as Hispanic White or with two or more races.

CONCLUSION

Although buprenorphine retention in OUD treatment improved for all veterans over the 15-year study period, veterans from most minoritized racial and ethnic groups fell further behind as gains in duration on therapy accrued primarily to non-Hispanic White veterans. Targeted interventions addressing specific challenges experienced by veterans with minoritized identities are needed to close gaps in retention on buprenorphine.

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.

Comparison of Treatment Receipt and Hospitalization Among Patients With Stimulant Use Disorder and/or Opioid Use Disorder in the Veterans Health Administration

OBJECTIVES

Stimulant use is a growing problem, but little is known about service utilization among patients with stimulant use disorder (StUD). In the context of the overdose crisis, much research has focused on patients with opioid use disorder (OUD). It is unclear how the characteristics, treatment receipt, and hospitalization of patients with StUD differ from patients with OUD.

METHODS

Electronic health record data were extracted for national Veterans Health Administration patients with a visit from March 1, 2020, to February 28, 2021 with StUD and/or OUD (N = 132,273). We compared patients with StUD without OUD to those with (1) co-occurring StUD + OUD and (2) OUD without StUD. Patient characteristics, substance use disorder treatment, and hospitalizations in the year following patients' first study period visit were descriptively compared. Treatment and hospitalization were also compared in adjusted regression models.

RESULTS

Compared with patients with OUD + StUD, those with StUD without OUD were less likely to receive outpatient (adjusted odds ratio [aOR] 0.49, 95% confidence interval [CI] 0.47-0.50) or any treatment (aOR 0.47, 95% CI 0.46-0.49). Compared with patients with OUD without StUD, those with StUD without OUD were less likely to receive outpatient (aOR 0.51, 95% CI 0.49-0.52) or any treatment (aOR 0.56, 95% CI 0.54-0.58) and more likely to receive residential treatment (aOR 2.18, 95% 2.05-2.30) and to be hospitalized (aOR 1.62, 95% 1.56-1.69).

CONCLUSIONS

Patients with StUD may be less likely to receive treatment and more likely to be hospitalized than patients with OUD. Efforts focused on mitigating hospitalization and increasing treatment receipt for patients with StUD are needed.

Sexually Transmitted Infection (STI) Incidence, STI Screening, and Human Immunodeficiency Virus Preexposure Prophylaxis Uptake in United States Veterans With Opioid Use Disorder in Long Island, New York

Background

Opioid use disorder (OUD) confers increased risk of contracting bloodborne and sexually transmitted infections (STIs). Limited data exist on infectious disease screening and preexposure prophylaxis (PrEP) usage among United States Veterans (USVs) with OUD, including persons who inject drugs (PWID). This study aimed to evaluate the epidemiology of human immunodeficiency virus (HIV), hepatitis C virus (HCV), bacterial STIs, and PrEP uptake in USVs with OUD, including PWID.

Methods

A retrospective chart review of USVs with OUD seeking care at Northport Veterans Affairs Medical Center between 2012 and 2022 was completed. Sociodemographics, HIV, HCV, STI testing rates and diagnosis, and PrEP uptake were compared between USVs, stratified by injection drug use history.

Results

We identified 502 USVs with OUD; 43% had a history of injection drug use. Overall, 2.2% of USVs had HIV and 28.7% had HCV. An STI was diagnosed in 10% of USVs, most frequently syphilis (1.8%). PWID were more likely to be tested for HIV (93.5% PWID vs. 73.1% non-PWID; P < .001), HCV (95.8% PWID vs. 80.8% non-PWID; P < .001), and syphilis (80% PWID vs. 69.2% non-PWID; P = .006). Total gonorrhea and chlamydia testing rates were 31.9% and 33.7%, respectively, without difference between the groups. PrEP was prescribed in 1.2% of USVs.

Conclusions

In USVs with OUD, gonorrhea and chlamydia screening occurred less frequently than syphilis, HCV, and HIV. PWID were more likely to be screened for HIV, HCV, and syphilis. PrEP uptake was low. Both PWID and non-PWID may benefit from increased STI screening and linkage to PrEP.

Development and validation of machine-learning algorithms predicting retention, overdoses, and all-cause mortality among US military veterans treated with buprenorphine for opioid use disorder

BACKGROUND

Buprenorphine for opioid use disorder (B-MOUD) is essential to improving patient outcomes; however, retention is essential.

OBJECTIVE

To develop and validate machine-learning algorithms predicting retention, overdoses, and all-cause mortality among US military veterans initiating B-MOUD.

METHODS

Veterans initiating B-MOUD from fiscal years 2006-2020 were identified. Veterans' B-MOUD episodes were randomly divided into training (80%;n = 45,238) and testing samples (20%;n = 11,309). Candidate algorithms [multiple logistic regression, least absolute shrinkage and selection operator regression, random forest (RF), gradient boosting machine (GBM), and deep neural network (DNN)] were used to build and validate classification models to predict six binary outcomes: 1) B-MOUD retention, 2) any overdose, 3) opioid-related overdose, 4) overdose death, 5) opioid overdose death, and 6) all-cause mortality. Model performance was assessed using standard classification statistics [e.g., area under the receiver operating characteristic curve (AUC-ROC)].

RESULTS

Episodes in the training sample were 93.0% male, 78.0% White, 72.3% unemployed, and 48.3% had a concurrent drug use disorder. The GBM model slightly outperformed others in predicting B-MOUD retention (AUC-ROC = 0.72). RF models outperformed others in predicting any overdose (AUC-ROC = 0.77) and opioid overdose (AUC-ROC = 0.77). RF and GBM outperformed other models for overdose death (AUC-ROC = 0.74 for both), and RF and DNN outperformed other models for opioid overdose death (RF AUC-ROC = 0.79; DNN AUC-ROC = 0.78). RF and GBM also outperformed other models for all-cause mortality (AUC-ROC = 0.76 for both). No single predictor accounted for >3% of the model's variance.

CONCLUSIONS

Machine-learning algorithms can accurately predict OUD-related outcomes with moderate predictive performance; however, prediction of these outcomes is driven by many characteristics.

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.

The Development of an Opioid Misuse Training Program for Physical Therapists: A Learning Community Approach

INTRODUCTION

Musculoskeletal pain and opioid misuse frequently co-occur.

REVIEW OF THE LITERATURE

The US Preventive Services Task Force calls for all health care providers to be trained to screen for misuse and/or opioid use disorder. The purpose of this study was to develop and implement an opioid misuse training program that could be used by physical therapists.

SUBJECTS

Thirteen practicing physical therapists were invited to participate in a curriculum development project.

METHODS

Using the Curriculum Framework, a collaborative learning approach was used to develop an opioid misuse training program and training manual for physical therapists. Four training sessions were provided virtually every 2 weeks. Topics included an introduction to the opioid crisis, screening, assessing, and communicating with patients and with the health care team about opioid misuse. Each didactic session was followed by a participant feedback session where participants provided recommendations on improving the training content and their impressions on the barriers and facilitators to incorporating the training into practice. A companion training manual was created and sent to participants for comment. Participants were asked over email to describe whether and how they incorporated training materials into clinical practice during the training curriculum.

RESULTS

All participants attended sessions 1-3. Twelve (92.3%) attended the fourth session. Based on the participants' feedback, training sessions were edited, and a companion training manual was finalized and distributed to each participant. After the fourth session, 9 participants (69.2%) reported using what they learned in the training. During the participant feedback sessions, participants regarded the training as important. Some participants expressed barriers to discussing opioids with patients and concerns about whether the training was within physical therapists' scope of practice.

DISCUSSION AND CONCLUSION

An iteratively developed training program for physical therapists to address opioid misuse was acceptable, feasible, and provided immediate practice change by most participants.

Buprenorphine Receipt and Retention for Opioid Use Disorder Following an Initiative to Increase Access in Primary Care

OBJECTIVES

Buprenorphine, a medication for opioid use disorder (OUD), is underutilized in general medical settings. Further, it is inequitably received by racialized groups and persons with comorbidities. The Veterans Health Administration launched an initiative to increase buprenorphine receipt in primary care. The project's objective was to identify patient-related factors associated with buprenorphine receipt and retention in primary care clinics (n = 18) participating in the initiative.

METHODS

Retrospective cohort quality improvement evaluation of patients 18 years or older with 2 or more primary care visits in a 1-year period and an OUD diagnosis in the year before the first primary care visit (index date). Buprenorphine receipt was the proportion of patients with OUD who received 1 or more buprenorphine prescriptions from primary care providers during the post-index year and retention the proportion who received buprenorphine for 180 days or longer.

RESULTS

Of 2880 patients with OUD seen in primary care, 11.7% (95% confidence interval [CI], 10.6%-12.9%) received buprenorphine in primary care, 58.2% (95% CI, 52.8%-63.3%) of whom were retained on buprenorphine for 180 days or longer. Patients with alcohol use disorder (adjusted odds ratio [AOR], 0.39; 95% CI, 0.27-0.57), nonopioid drug use disorder (AOR, 0.64; 95% CI, 0.45-0.93), and serious mental illness (AOR, 0.60; 95% CI, 0.37-0.97) had lower buprenorphine receipt. Those with an anxiety disorder had higher buprenorphine receipt (AOR, 1.42; 95% CI, 1.04-1.95). Buprenorphine receipt (AOR, 0.55; 95% CI, 0.35-0.87) and 180-day retention (AOR, 0.40; 95% CI, 0.19-0.84) were less likely among non-Hispanic Black patients.

CONCLUSIONS

Further integration of addiction services in primary care may be needed to enhance buprenorphine receipt for patients with comorbid substance use disorders, and interventions are needed to address disparities in receipt and retention among non-Hispanic Black patients.

"The Only Reason I Am Willing to Do It at All": Evaluation of VA's SUpporting Primary care Providers in Opioid Risk reduction and Treatment (SUPPORT) Center

OBJECTIVES

Medication treatment for opioid use disorder (MOUD) is effective and recommended for outpatient settings. We implemented and evaluated the SUpporting Primary care Providers in Opioid Risk reduction and Treatment (SUPPORT) Center-a quality improvement partnership to implement stepped care for MOUD in 2 Veterans Health Administration (VA) primary care (PC) clinics.

METHODS

SUPPORT provided a dedicated clinical team (nurse practitioner prescriber and social worker) and stepped care ([1] identification, assessment, referral; [2] MOUD induction; [3] stabilization; and [4] maintenance supporting PC providers [PCPs] to initiate and/or sustain treatment) coupled with ongoing internal facilitation (consultation, trainings, informatics support). Qualitative interviews with stakeholders (PCPs and patients) and meeting notes identified barriers and facilitators to implementation. Electronic health record and patient tracking data measured reach, adoption, and implementation outcomes descriptively.

RESULTS

SUPPORT's implementation barriers included the need for an X-waiver, VA's opioid tapering policies, patient and PCP knowledge gaps and PCP discomfort, and logistical compatibility and sustainability challenges for clinics. SUPPORT's dedicated clinical staff, ongoing internal facilitation, and high patient and PCP satisfaction were key facilitators. SUPPORT (January 2019 to September 2021) trained 218 providers; 63 received X-waivers, and 23 provided MOUD (10.5% of those trained). SUPPORT provided care to 167 patients, initiated MOUD for 33, and provided education and naloxone to 72 (all = 0 in year before launch).

CONCLUSIONS

SUPPORT reached many PCPs and patients and resulted in small increases in MOUD prescribing and high levels of stakeholder satisfaction. Dedicated clinical staff was key to observed successes. Although resource-intensive, SUPPORT offers a potential model for outpatient MOUD provision.

Patients' Perspectives on Discontinuing Buprenorphine for the Treatment of Opioid Use Disorder

OBJECTIVES

Buprenorphine and other medications for opioid use disorder (OUD) are recommended as standard of care in the treatment of OUD and are associated with positive health and addiction-related outcomes. Despite benefits, discontinuation is common, with half of patients discontinuing in the first year of treatment. Addressing OUD is a major clinical priority, yet little is known about the causes of medication discontinuation from the patient perspective.

METHODS

From March 2021 to April 2022, we conducted qualitative interviews with patients who had discontinued buprenorphine for the treatment of OUD within the past 12 months. Eligible participants were selected from 2 Veterans Health Administration Health Care Systems in Oregon. Coding and analysis were guided by conventional qualitative content analysis.

RESULTS

Twenty participants completed an interview; 90% were White and 90% were male, and the mean age was 54.2 years. Before discontinuation, participants had received buprenorphine for 8.3 months on average (range, 1-40 months); 80% had received buprenorphine for less than 12 months. Qualitative analysis identified the following themes relating to discontinuation: health system barriers (eg, logistical hurdles, rules and policy violations), medication effects (adverse effects; attributed adverse effects, lack of efficacy in treating chronic pain) and desire for opioid use. Patient description of decisions to discontinue buprenorphine could be multicausal, reflecting provider or system-level barriers in interaction with patient complexity or medication ambivalence.

CONCLUSIONS

Study results identify several actionable ways OUD treatment could be modified to enhance patient retention.

Problem Opioid Use Among US Military Veterans: Prevalence, Correlates, and Psychiatric Characteristics

OBJECTIVE

Problem opioid use (POU) is a serious public health crisis in the United States. However, little research has examined the prevalence, correlates, and psychiatric characteristics of POU in vulnerable segments of the population, such as US military veterans.

METHODS

Data were analyzed from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 2441 US veterans. Multivariable logistic regression models were conducted to identify correlates and psychiatric correlates of POU (defined as a positive screen on the Tobacco, Alcohol, Prescription Medication, and Other Substance Use Tool).

RESULTS

A total 3.0% (95% confidence interval, 2.0%-4.5%) of US veterans screened positive for POU. Black, non-Hispanic race/ethnicity (odds ratio [OR], 3.83), lifetime alcohol use disorder (OR, 3.38), major depressive disorder (MDD; OR, 2.52), greater number of medical conditions (OR, 1.15), and disability in instrumental activities of daily living (IADL); OR, 1.86) were independently associated with POU. A significant interaction between IADL disability and MDD was observed (OR, 10.73)-among veterans with IADL disability, those with MDD had more than 6-fold greater POU than those without MDD (20.6% vs 3.2%). Furthermore, POU was associated with 2- to 3-folds greater odds of current generalized anxiety disorder and current posttraumatic stress disorder, and lifetime suicide attempt.

CONCLUSIONS

POU affects 3.0% of US veterans and is associated with Black race/ethnicity, lifetime physical and mental health morbidities, as well as current psychiatric disorders and lifetime suicide attempts. Results underscore the importance of assessing physical and mental health disorders in veterans at-risk for POU and addressing co-occurring psychiatric disorders associated with POU in this population.

Characterizing acute and postsurgical pain management in patients receiving buprenorphine or buprenorphine/naloxone

BACKGROUND

There is currently a clinical dilemma in treating acute pain in patients receiving long-term buprenorphine products.

METHODS

This is a retrospective cohort review involving patients receiving long-term buprenorphine therapy who either underwent a surgical procedure or presented to an emergency department (ED) for acute pain between January 1, 2012 and January 1, 2022. Patients were excluded if opioids were prescribed 30 days before the index date. Chart reviews were conducted to characterize buprenorphine treatment strategies and the addition of new pain medications. Chart review revealed (1) incidence of opioid use disorder (OUD) relapse, (2) hospital re-presentation for pain or OUD, (3) fatal and non-fatal overdose, and (4) all-cause mortality and suicidality. Descriptive statistics were used to analyze results.

RESULTS

A total of 70 of 259 screened patients met inclusion criteria. The mean (±SD) age was 50.3 ± 13 years, 92.9% male, 64.3% White, and 78.6% had an OUD diagnosis. While 84.3% presented to the ED, 15.7% underwent surgical procedures. For the primary endpoint, the total daily dose of buprenorphine or buprenorphine/naloxone from index date to discharge was continued in 90.0%, increased in 2.9%, decreased in 1.4%, and discontinued in 5.7% of cases. At discharge, 46.2% were prescribed an additional pain medication. A total of 7.1% re-presented for pain or OUD relapse, 15.7% experienced an OUD relapse, 1.4% experienced new-onset suicidality, and 1.4% experience all-cause mortality within 90 days of the index date. No fatal or non-fatal opioid overdoses were observed.

CONCLUSION

The most commonly observed practice was continuing buprenorphine doses in patients with acute or postsurgical pain, which was effective and safe. Although further data is necessary to fully elucidate these findings, the data herein may suggest that clinicians can safely continue buprenorphine doses in the acute pain setting in patients receiving these products chronically.

Continuation of Buprenorphine During Hospitalization and Subsequent Retention in Therapy: an Observational Study in Veterans Administration Hospitals

BACKGROUND

Inpatient hospitalization has the potential to disrupt buprenorphine therapy.

OBJECTIVE

Among patients receiving outpatient buprenorphine prior to admission, we determined the rate of discontinuation during medical and surgical admissions to VA hospitals and its association with subsequent post-discharge continuation of buprenorphine therapy.

DESIGN AND MAIN MEASURES

We conducted an observational study using Veterans Administration data from 10/1/2018 to 3/31/2020 for all medical and surgical admissions where Veterans had active buprenorphine prescriptions at the time of admission. Pre-admission buprenorphine prescriptions were categorized as either sublingual (presumed indication for opioid use disorder (OUD)) or buccal/topical (presumed indication for pain). The primary measure of post-discharge buprenorphine receipt was any outpatient buprenorphine prescription dispensed between 1 day prior to discharge and 60 days following discharge.

KEY RESULTS

A total of 830 unique inpatient hospitalizations to medical or surgical services occurred among Veterans receiving sublingual (48.3%) or buccal/topical (51.7%) buprenorphine prior to admission. Fewer than half (43.9%) of these patients received buprenorphine at some point during the medical or surgical portion of their hospital stay. Among the 766 patients discharged from a medical or surgical unit, 74.3% received an outpatient buprenorphine prescription within the 60 days following discharge (80.2% sublingual and 69.1% buccal/topical). Among patients who had received buprenorphine during the final 36 h prior to discharge, subsequent outpatient buprenorphine receipt was observed in 94.0%, compared to only 63.7% among those not receiving buprenorphine during the final 36 h (χ2 = 83.5, p < 0.001).

CONCLUSION

Inpatient buprenorphine administrations near the time of discharge were highly predictive of continued outpatient therapy and a significant subset of patients did not continue or reinitiate buprenorphine therapy following discharge. As recommendations for perioperative and inpatient management of buprenorphine coalescence around continuation, efforts are needed to optimize hospital-based buprenorphine practices.

Weight change in a national cohort of U.S. Military Veterans engaged in medication treatment for opioid use disorder

Medication treatments for opioid use disorder (MOUD) save lives and improve outcomes for countless individuals. However, data suggest the potential for significant weight gain during methadone treatment and little is known about weight change during buprenorphine treatment. Using Veteran Health Administration administrative data from fiscal year 2017 to fiscal year 2019, two cohorts were created: 1) Veterans diagnosed with opioid use disorder (OUD) taking methadone (N = 1425); and 2) Veterans diagnosed with OUD taking buprenorphine (N = 3756). Linear mixed models were used to analyze weight change during the first MOUD treatment episode in the observation period. Random slopes and intercepts were included in the model to estimate variation in BMI across individuals and time. The data revealed a slight upward trend in BMI over the course of treatment. Specifically, a daily increase of 0.004 for Veterans in methadone treatment and 0.002 for Veterans in buprenorphine treatment was observed. This translates to a gain of about 10 pounds over the course of 1 year of methadone treatment and 5 pounds for 1 year of buprenorphine treatment for a Veteran of average height and weight. The amount of weight gain in methadone treatment is significantly less than other published findings, but nonetheless indicates that assessment and discussions between patients and providers related to weight may be warranted.

Impact of an intervention to implement provision of opioid use disorder medication among patients with and without co-occurring substance use disorders

INTRODUCTION

Co-occurring substance use disorders (SUDs) are common among people with opioid use disorder (OUD) and known to hinder receipt of medications for OUD (MOUD). It is important to understand how MOUD care implemented outside of SUD specialty settings impacts access for patients with co-occurring SUDs. The Veterans Health Administration's (VA) Stepped Care for Opioid Use Disorder Train the Trainer (SCOUTT) initiative was implemented in primary care, mental health, and pain clinics in 18 VA facilities, and was found to increase MOUD receipt. This study assessed the SCOUTT initiative's impact among patients with and without co-occurring SUDs.

METHODS

This study used a controlled interrupted time series design. We extracted electronic health record data for patients with OUD with visits in SCOUTT intervention or matched comparison clinics during the post-implementation year (9/1/2018-8/31/2019). We examined the monthly proportion of patients who received MOUD in SCOUTT intervention or comparison clinics (primary care, mental health, and pain clinics), or in a VA SUD specialty clinic (where patients may have been referred), during the pre- and post-implementation years. Segmented logistic regression models estimated pre-post changes in outcomes (immediate level change from the final month of the pre-implementation period to the first month of the post-implementation period, change in trend/slope) in intervention vs. comparison facilities, adjusting for patient characteristics and pre-implementation trends. We stratified analyses by the presence of co-occurring SUDs.

RESULTS

Among patients without co-occurring SUDs, the pre-post trend/slope change in MOUD received in SCOUTT intervention or comparison clinics was greater in intervention vs. comparison facilities (adjusted odds ratio [aOR]: 1.06, 95% confidence interval [CI]: 1.02-1.10), and the immediate increase in MOUD received in SUD clinics was greater in intervention vs. comparison facilities (aOR: 1.12, 95% CI: 1.02-1.22). These changes did not significantly differ in intervention vs. comparison facilities among patients with co-occurring SUDs.

CONCLUSIONS

The SCOUTT initiative may have increased MOUD receipt primarily among patients without co-occurring SUDs. Focusing on increasing MOUD receipt for patients with co-occurring SUDs may improve the overall effectiveness of MOUD implementation efforts.

Healthcare costs and use before and after opioid overdose in Veterans Health Administration patients with opioid use disorder

AIMS

To compare healthcare costs and use between United States (US) Veterans Health Administration (VHA) patients with opioid use disorder (OUD) who experienced an opioid overdose (OD cohort) and patients with OUD who did not experience an opioid overdose (non-OD cohort).

DESIGN

This is a retrospective cohort study of administrative and clinical data.

SETTING

The largest integrated national health-care system is the US Veterans Health Administration's healthcare systems.

PARTICIPANTS

We included VHA patients diagnosed with OUD from October 1, 2017 through September 30, 2018. We identified the index date of overdose for patients who had an overdose. Our control group, which included patients with OUD who did not have an overdose, was randomly assigned an index date. A total of 66 513 patients with OUD were included for analysis (OD cohort: n = 1413; non-OD cohort: n = 65 100).

MEASUREMENTS

Monthly adjusted healthcare-related costs and use in the year before and after the index date. We used generalized estimating equation models to compare patients with an opioid overdose and controls in a difference-in-differences framework.

FINDINGS

Compared with the non-OD cohort, an opioid overdose was associated with an increase of $16 890 [95% confidence interval (CI) = $15 611-18 169; P < 0.001] in healthcare costs for an estimated $23.9 million in direct costs to VHA (95% CI = $22.1 million, $25.7 million) within the 30 days following overdose after adjusting for baseline characteristics. Inpatient costs ($13 515; 95% CI = $12 378-14 652; P < 0.001) reflected most of this increase. Inpatient days (+6.15 days; 95% CI, = 5.33-6.97; P < 0.001), inpatient admissions (+1.01 admissions; 95% CI = 0.93-1.10; P < 0.001) and outpatient visits (+1.59 visits; 95% CI = 1.34-1.84; P < 0.001) also increased in the month after opioid overdose. Within the overdose cohort, healthcare costs and use remained higher in the year after overdose compared with pre-overdose trends.

CONCLUSIONS

The US Veterans Health Administration patients with opioid use disorder (OUD) who have experienced an opioid overdose have increased healthcare costs and use that remain significantly higher in the month and continuing through the year after overdose than OUD patients who have not experienced an overdose.

What Contributes to Sustainability? Examining Access to Medications for Opioid Use Disorder in Low-Adopting VHA Facilities

BACKGROUND

Successful implementation can increase the availability of evidence-based treatments but continued patient access can be threatened if there is not deliberate focus on sustainment. Real-world examples are needed to elucidate contributors to sustainability.

OBJECTIVE

We examined sustainability of outcomes of a study which tested a 12-month external facilitation intervention. The study evaluated change in access to medications for opioid use disorder (MOUD) in Veterans Health Administration (VHA) facilities in the lowest quartile of MOUD prescribing.

DESIGN

Convergent mixed-methods design.

PARTICIPANTS

Thirty-nine providers and leaders from eight VHA facilities.

APPROACH

Thirty-minute post-implementation telephone interviews explored whether barriers identified pre-implementation were successfully addressed, the presence of any new challenges, helpfulness of external facilitation, and plans for sustaining MOUD access. Interviews were analyzed using a rapid turn-around approach. VHA administrative data were used to characterize the facilities and assess their ratio of patients with an OUD diagnosis receiving MOUD (MOUD/OUD ratio) at the end of a 9-month sustainability period.

KEY RESULTS

Commonly reported contributors to sustained MOUD access included national attention on the opioid epidemic, accountability created by study participation, culture shift in MOUD acceptability, leadership support, and plans to build on initial progress. Frequently reported barriers included staffing issues and lack of MOUD-devoted time; the need to overhaul existing policies, practices, and/or processes; and fear and anxiety about MOUD prescribing. All facilities either maintained MOUD/OUD ratio improvement (n = 2) or further improved (n = 6) at the end of sustainability. Facilities with the highest and lowest ratio at the end of sustainability used a team-based approach to MOUD delivery; however, organizational setting differences may have impacted overall MOUD access.

CONCLUSIONS

Ensuring stable and consistent staff, and sufficient time dedicated to MOUD are critical to sustaining access to evidence-based treatment in low-adopting facilities. This study highlights the importance of investing in local, system-level changes to improve and sustain access to effective treatments.

Costs of implementing a multi-site facilitation intervention to increase access to medication treatment for opioid use disorder

BACKGROUND

The United States has been grappling with the opioid epidemic, which has resulted in over 75,000 opioid-related deaths between April 2020 and 2021. Evidence-based pharmaceutical interventions (buprenorphine, methadone, and naltrexone) are available to reduce opioid-related overdoses and deaths. However, adoption of these medications for opioid use disorder has been stifled due to individual- and system-level barriers. External facilitation is an evidence-based implementation intervention that has been used to increase access to medication for opioid use disorder (MOUD), but the implementation costs of external facilitation have not been assessed. We sought to measure the facility-level direct costs of implementing an external facilitation intervention for MOUD to provide decision makers with estimates of the resources needed to implement this evidence-based program.

METHODS

We performed a cost analysis of the pre-implementation and implementation phases, including an itemization of external facilitation team and local site labor costs. We used labor estimates from the Bureau of Labor and Statistics, and sensitivity analyses were performed using labor estimates from the Veterans Health Administration (VHA) Financial Management System general ledger data.

RESULTS

The average total costs for implementing an external facilitation intervention for MOUD per site was $18,847 (SD 6717) and ranged between $11,320 and $31,592. This translates to approximately $48 per patient with OUD. Sites with more encounters and participants with higher salaries in attendance had higher costs. This was driven mostly by the labor involved in planning and implementation activities. The average total cost of the pre-implementation and implementation activities were $1031 and $17,816 per site, respectively. In the sensitivity analysis, costs for VHA were higher than BLS estimates likely due to higher wages.

CONCLUSIONS

Implementing external facilitation to increase MOUD prescribing may be affordable depending on the payer's budget constraints. Our study reported that there were variations in the time invested at each phase of implementation and the number and type of participants involved with implementing an external facilitation intervention. Participant composition played an important role in total implementation costs, and decision makers will need to identify the most efficient and optimal number of stakeholders to involve in their implementation plans.

Trends in substance use disorder diagnoses among Veterans, 2009-2019

BACKGROUND AND OBJECTIVES

Substance use disorder (SUD) represents a substantial health burden to US Veterans. We aimed to quantify recent time trends in Veterans' substance-specific disorders using Veterans Health Administration (VA) data.

METHODS

We identified Veteran VA patients for fiscal years (FY) 2010-2019 (October 1, 2009-September 9, 2019) and extracted patient demographics and diagnoses from electronic health records (~6 million annually). We defined alcohol, cannabis, cocaine, opioid, sedative, and stimulant use disorders with ICD-9 (FY10-FY15) or ICD-10 (FY16-FY19) codes and variables for polysubstance use disorder, drug use disorder (DUD), and SUD.

RESULTS

Diagnoses for substance-specific disorders (excluding cocaine), polysubstance use disorder, DUD, and SUD increased 2%-13% annually for FY10-FY15. Alcohol, cannabis, and stimulant use disorders increased 4%-18% annually for FY16-FY19, while cocaine, opioid, and sedative use disorders changed by ≤1%. Stimulant and cannabis use disorder diagnoses increased most rapidly, and older Veterans had the largest increases across substances.

DISCUSSION AND CONCLUSIONS

Rapid increases in cannabis and stimulant use disorder present a treatment challenge and key subgroups (e.g., older adults) may require tailored screening and treatment options. Diagnoses for SUD are increasing among Veterans overall, but there is important heterogeneity by substance and subgroup. Efforts to ensure access to evidence-based treatment for SUD may require greater focus on cannabis and stimulants, particularly for older adults.

SCIENTIFIC SIGNIFICANCE

These findings represent the first assessment of time trends in substance-specific disorders among Veterans, overall and by age and sex. Notable findings include large increases in diagnoses for cannabis and stimulant use disorder and among older adults.

Increasing Access to Buprenorphine for Opioid Use Disorder in Primary Care: an Assessment of Provider Incentives

BACKGROUND

Primary care providers (PCPs) are essential to increasing access to office-based buprenorphine medication treatment for opioid use disorder (B-MOUD). Barriers to B-MOUD prescribing are well-documented, but there is little information regarding incentives to overcome these barriers.

OBJECTIVE

To identify optimal incentives for PCPs to promote B-MOUD prescribing and compare incentive preferences across provider and practice characteristics.

DESIGN

We surveyed PCPs using best-worst scaling (BWS) to prioritize seven potential incentives for B-MOUD prescribing (monetary compensation, paid vacation, protected time, professional development, reduced workload, service recognition, clinical resources). We then used a direct elicitation approach to determine preferred incentive levels (e.g., monetary thresholds) and types (e.g., specific clinical resources).

PARTICIPANTS

Primary care physicians and advanced practice providers (APPs) at a large Department of Veterans Affairs healthcare system.

MAIN MEASURES

B-MOUD prescribing incentive preferences and relative preference levels using descriptive statistics and conditional logistic regression with relative importance scale transformation (coefficients sum to 100, higher coefficient=greater importance).

KEY RESULTS

Fifty-three PCPs responded (73% response), including 47% APPs and 36% from community-based clinics. Reduced workload (relative importance score=26.8), protected time (18.7), and clinical resources (16.8) were significantly more preferred (Ps < 0.001) than professional development (10.5), paid vacation (10.3), or service recognition (1.5). Relative importance of monetary compensation varied between physicians (12.6) and APPs (17.5) and between PCPs located at a medical center (11.4) versus community clinic (22.3). APPs were more responsive than physicians to compensation increases of $5000 and $12,000 but less responsive to $25,000; trends were similar for medical center versus community clinic PCPs. The most frequently requested clinical resource was on-demand consult access to an addiction specialist.

CONCLUSIONS

Interventions promoting workload reductions, protected time, and clinical resources could increase access to B-MOUD in primary care. Monetary incentives may be additionally needed to improve B-MOUD prescribing among APPs and within community clinics.

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.

Treating opioid use disorder in veterans with co-occurring substance use: a qualitative study with buprenorphine providers in primary care, mental health, and pain settings

BACKGROUND

Most people with opioid use disorder (OUD) have co-occurring substance use, which is associated with lower receipt of OUD medications (MOUD). Expanding MOUD provision and care linkage outside of substance use disorder (SUD) specialty settings is a key strategy to increase access. Therefore, it is important to understand how MOUD providers in these settings approach care for patients with co-occurring substance use. This qualitative study of Veterans Health Administration (VA) clinicians providing buprenorphine care in primary care, mental health, and pain settings aimed to understand (1) their approach to addressing OUD in patients with co-occurring substance use, (2) perspectives on barriers/facilitators to MOUD receipt for this population, and (3) support needed to increase MOUD receipt for this population.

METHODS

We interviewed a purposive sample of 27 clinicians (12 primary care, 7 mental health, 4 pain, 4 pharmacists) in the VA northwest network. The interview guide assessed domains of the Tailored Implementation for Chronic Diseases Checklist. Interviews were transcribed and qualitatively analyzed using inductive content analysis.

RESULTS

Participants reported varied approaches to identifying co-occurring substance use and addressing OUD in this patient population. Although they reported that this topic was not clearly addressed in clinical guidelines or training, participants generally felt that patients with co-occurring substance use should receive MOUD. Some viewed their primary role as providing this care, others as facilitating linkage to OUD care in SUD specialty settings. Participants reported multiple barriers and facilitators to providing buprenorphine care to patients with co-occurring substance use and linking them to SUD specialty care, including provider, patient, organizational, and external factors.

CONCLUSIONS

Efforts are needed to support clinicians outside of SUD specialty settings in providing buprenorphine care to patients with co-occurring substance use. These could include clearer guidelines and policies, more specific training, and increased care integration or cross-disciplinary collaboration. Simultaneously, efforts are needed to improve linkage to specialty SUD care for patients who would benefit from and are willing to receive this care, which could include increased service availability and improved referral/hand-off processes. These efforts may increase MOUD receipt and improve OUD care quality for patients with co-occurring substance use.

Associations Between Distinct Co-occurring Substance Use Disorders and Receipt of Medications for Opioid Use Disorder in the Veterans Health Administration

OBJECTIVES

Among people with opioid use disorder (OUD), having a co-occurring substance use disorder (SUD) is associated with lower likelihood of receiving OUD treatment medications (MOUD). However, it is unclear how distinct co-occurring SUDs are associated with MOUD receipt. This study examined associations of distinct co-occurring SUDs with initiation and continuation of MOUD among patients with OUD in the national Veterans Health Administration (VA).

METHODS

Electronic health record data were extracted for outpatients with OUD who received care August 1, 2016, to July 31, 2017. Analyses were conducted separately among patients without and with prior-year MOUD receipt to examine initiation and continuation, respectively. SUDs were measured using diagnostic codes; MOUD receipt was measured using prescription fills/clinic visits. Adjusted regression models estimated likelihood of following-year MOUD receipt for patients with each co-occurring SUD relative to those without.

RESULTS

Among 23,990 patients without prior-year MOUD receipt, 12% initiated in the following year. Alcohol use disorder (adjusted incidence rate ratio [aIRR], 0.80; 95% confidence interval [CI], 0.72-0.90) and cannabis use disorder (aIRR, 0.78; 95% CI, 0.70-0.87) were negatively associated with initiation. Among 11,854 patients with prior-year MOUD receipt, 83% continued in the following year. Alcohol use disorder (aIRR, 0.94; 95% CI, 0.91-0.97), amphetamine/other stimulant use disorder (aIRR, 0.94; 95% CI, 0.90-0.99), and cannabis use disorder (aIRR, 0.95; 95% CI, 0.93-0.98) were negatively associated with continuation.

CONCLUSIONS

In this study of national VA outpatients with OUD, those with certain co-occurring SUDs were less likely to initiate or continue MOUD. Further research is needed to identify barriers related to specific co-occurring SUDs.

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.

Effect of a Veterans Health Administration mandate to case review patients with opioid prescriptions on mortality among patients with opioid use disorder: a secondary analysis of the STORM randomized control trial

AIMS

The Veterans Health Administration (VHA) implemented the Stratification Tool for Opioid Risk Mitigation (STORM) to reduce the risk of serious adverse events (SAE) among patients with opioid analgesic prescriptions. VHA facilities were mandated to case review patients identified as high risk by STORM. The aim of this study was to measure the effect of this mandate on all-cause mortality and SAEs among VHA patients newly diagnosed with opioid use disorder (OUD).

DESIGN

Secondary analysis of a stepped-wedged cluster randomized controlled trial conducted at all 140 VHA facilities, with facility as the unit of randomization, from 2018 to 2020.

SETTING AND PARTICIPANTS

United States VHA facilities were randomized to case review the top 1 or 5% of high-risk patients prescribed opioid analgesics identified by STORM. A total of 28 251 patients were diagnosed with OUD during the trial and were considered control or treatment depending on the status of the facility where they received their OUD diagnosis. Post-hoc analyses among patients who had at least one opioid analgesic prescription in the 90 days prior to diagnosis were conducted and were then stratified by receipt of a prescription in the 90 days following diagnosis to assess the sensitivity of results to opioid discontinuation.

MEASUREMENTS

All-cause mortality and opioid-related, drug-related, suicide-related and other SAEs within 90 days of OUD diagnosis.

FINDINGS

Mandated case review increased the odds of 90-day mortality [odds ratio (OR) = 1.74, 95% confidence interval (CI) = 1.06, 2.87], but did not significantly change the odds of SAEs. Among patients who received an opioid prescription prior to but not after OUD diagnosis, the odds of all-cause mortality within 90 days was 5.87 (95% CI = 1.85, 18.58) relative to control patients.

CONCLUSIONS

Veterans Health Administration patients newly diagnosed with opioid use disorder experienced increased all-cause mortality following expansion of a case review mandate for high-risk patients prescribed opioids.

Healthcare quality measures in implementation research: advantages, risks and lessons learned

Implementation studies evaluate strategies to move evidence-based practices into routine clinical practice. Often, implementation scientists use healthcare quality measures to evaluate the integration of an evidence-based clinical practice into real-world healthcare settings. Healthcare quality measures have standardized definitions and are a method to operationalize and monitor guideline-congruent care. Implementation scientists can access existing data on healthcare quality measures through various sources (e.g. operations-calculated), or they can calculate the measures directly from healthcare claims and administrative data (i.e. researcher-calculated). Implementation scientists need a better understanding of the advantages and disadvantages of these methods of obtaining healthcare quality data for designing, planning and executing an implementation study. The purpose of this paper is to describe the advantages, risks and lessons learned when using operations- versus researcher-calculated healthcare quality measures in site selection, implementation monitoring and implementation outcome evaluation. A key lesson learned was that relying solely on operations-calculated healthcare quality measures during an implementation study poses risks to site selection, accurate feedback on implementation progress to stakeholders, and the integrity of study results. A possible solution is using operations-calculated quality measures for monitoring of evidence-based practice uptake and researcher-calculated measures for site section and outcomes evaluation. This approach provides researchers greater control over the data and consistency of the measurement from site selection to outcomes evaluation while still retaining measures that are familiar and understood by key stakeholders whom implementation scientists need to engage in practice change efforts.

Sociodemographic differences in quality of treatment to Medicaid enrollees receiving buprenorphine

Background: Buprenorphine is a key medication to treat opioid use disorder, but little is known about how treatment quality varies across sociodemographic groups. Objective: We examined measures of treatment quality and explored variation by sociodemographic factors. Methods: We used Medicaid MAX data from 50 states from 2006 to 2014 to identify buprenorphine treatment episodes (N = 317,494). We used multivariable logistic regression to examine the quality of buprenorphine treatment along four dimensions: (1) sufficient duration, (2) effective dosage, and concurrent prescribing of (3) opioid analgesics and (4) benzodiazepines. We explored how quality varied by race/ethnicity, age, sex, and urbanicity. Results: In adjusted models, compared to non-Hispanic White individuals, non-Hispanic Black and Hispanic individuals had lower odds of receiving effective dosage (aORs = 0.79 and 0.89, respectively) and sufficient duration (aORs = 0.64 and 0.71, respectively), and lower odds of concurrent prescribing of opioid analgesics (aORs = 0.86 and 0.85, respectively) and benzodiazepines (aORs = 0.51 and 0.59, respectively). Older individuals had higher odds of sufficient duration (aORs from 1.21-1.33), but also had higher odds of concurrent opioid analgesics prescribing (aORs from 1.29-1.56) and benzodiazepines (aORs from 1.44-1.99). Females had higher odds of sufficient duration (aOR = 1.12), but lower odds of effective dosage (aOR = 0.77) and higher odds of concurrent prescribing of opioid analgesics (aOR = 1.25) and benzodiazepines (aOR = 1.16). Compared to individuals living in metropolitan areas, individuals living in non-metropolitan areas had higher odds of sufficient duration (aORs = 1.11 and 1.24) and effective dosage (aORs = 1.06 and 1.33), and lower odds of concurrent prescribing (aORs from 0.81-0.98). Conclusions: Black and Hispanic individuals were less likely to receive effective buprenorphine dosage and sufficient duration. Quality results were mixed for older and female individuals; although these individuals were more likely to receive treatment of sufficient duration, they were also more likely to be concurrently prescribed potentially contraindicated medications, and females were less likely to receive effective dosage. Findings raise concerns about adequacy of care for minority and other at-risk populations.

Patient-centered quality measurement for opioid use disorder: Development of a taxonomy to address gaps in research and practice

Background: Evidence-based treatment is provided infrequently and inconsistently to patients with opioid use disorder (OUD). Treatment guidelines call for high-quality, patient-centered care that meets individual preferences and needs, but it is unclear whether current quality measures address individualized aspects of care and whether measures of patient-centered OUD care are supported by evidence. Methods: We conducted an environmental scan of OUD care quality to (1) evaluate patient-centeredness in current OUD quality measures endorsed by national agencies and in national OUD treatment guidelines; and (2) review literature evidence for patient-centered care in OUD diagnosis and management, including gaps in current guidelines, performance data, and quality measures. We then synthesized these findings to develop a new quality measurement taxonomy that incorporates patient-centered aspects of care and identifies priority areas for future research and quality measure development. Results: Across 31 endorsed OUD quality measures, only two measures of patient experience incorporated patient preferences and needs, while national guidelines emphasized providing patient-centered care. Among 689 articles reviewed, evidence varied for practices of patient-centered care. Many practices were supported by guidelines and substantial evidence, while others lacked evidence despite guideline support. Our synthesis of findings resulted in EQuIITable Care, a taxonomy comprised of six classifications: (1) patient Experience and engagement, (2) Quality of life; (3) Identification of patient risks; (4) Interventions to mitigate patient risks; (5) Treatment; and (6) Care coordination and navigation. Conclusions: Current quality measurement for OUD lacks patient-centeredness. EQuIITable Care for OUD provides a roadmap to develop measures of patient-centered care for OUD.

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.

Use of and Retention on Video, Telephone, and In-Person Buprenorphine Treatment for Opioid Use Disorder During the COVID-19 Pandemic

IMPORTANCE

The coronavirus disease 2019 (COVID-19) pandemic prompted policy changes to allow increased telehealth delivery of buprenorphine, a potentially lifesaving medication for opioid use disorder (OUD). It is unclear how characteristics of patients who access different treatment modalities (in-person vs telehealth, video vs telephone) vary, and whether modality is associated with retention-a key indicator of care quality.

OBJECTIVES

To compare patient characteristics across receipt of different treatment modalities and to assess whether modality was associated with retention during the year following COVID-19-related policy changes.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study was conducted in the national Veterans Health Administration. Participants included patients who received buprenorphine for OUD during March 23, 2020, to March 22, 2021. Analyses examining retention were stratified by buprenorphine initiation time (year following COVID-19-related changes; prior to COVID-19-related changes).

EXPOSURES

Patient characteristics; treatment modality (at least 1 video visit, at least 1 telephone visit but no video, only in-person).

MAIN OUTCOMES AND MEASURES

Treatment modality; 90-day retention.

RESULTS

Among 17 182 patients, 7094 (41.3%) were aged 30 to 44 years and 6251 (36.4%) were aged 45 to 64 years; 15 835 (92.2%) were male, 14 085 (82.0%) were White, and 16 292 (94.8%) were non-Hispanic; 6547 (38.1%) had at least 1 video visit, 8524 (49.6%) had at least 1 telephone visit but no video visit, and 2111 (12.3%) had only in-person visits. Patients who were younger, male, Black, unknown race, Hispanic, non-service connected, or had specific mental health/substance use comorbidities were less likely to receive any telehealth. Among patients who received telehealth, those who were older, male, Black, non-service connected, or experiencing homelessness and/or housing instability were less likely to have video visits. Retention was significantly higher for patients with telehealth compared with only in-person visits regardless of initiation time (for initiated in year following COVID-19-related changes: adjusted odds ratio [aOR], 1.31; 95% CI, 1.12-1.53; for initiated prior to COVID-19-related changes: aOR, 1.23; 95% CI, 1.08-1.39). Among patients with telehealth, higher retention was observed in those with video visits compared with only telephone for patients who initiated in the year following COVID-19 (aOR, 1.47; 95% CI, 1.26-1.71).

CONCLUSIONS AND RELEVANCE

In this cross-sectional study, many patients accessed buprenorphine via telephone and some were less likely to have any video visits. These findings suggest that discontinuing or reducing telephone access may disrupt treatment for many patients, particularly groups with access disparities such as Black patients and those experiencing homelessness. Telehealth was associated with increased retention for both new and continuing patients.

Impact of COVID-19 Telehealth Policy Changes on Buprenorphine Treatment for Opioid Use Disorder

OBJECTIVE

The authors examined the impact of COVID-19-related policies reducing barriers to telehealth delivery of buprenorphine treatment for opioid use disorder (OUD) on buprenorphine treatment across different modalities (telephone, video, and in-person visits).

METHODS

This was a national retrospective cohort study with interrupted time-series analyses to examine the impact of policy changes in March 2020 on buprenorphine treatment for OUD in the Veterans Health Administration, during the year before the start of the COVID-19 pandemic (March 2019 to February 2020) and during the first year of the pandemic (March 2020 to February 2021). The authors also examined trends in the use of telephone, video, and in-person visits for buprenorphine treatment and compared patient demographic characteristics and retention in buprenorphine treatment across the two periods.

RESULTS

The number of patients receiving buprenorphine increased from 13,415 in March 2019 to 15,339 in February 2021. By February 2021, telephone visits were used by the most patients (50.2%; 4,456 visits), followed by video visits (32.4%; 2,870 visits) and in-person visits (17.4%; 1,544 visits). During the pre-pandemic period, the number of patients receiving buprenorphine increased significantly by 103 patients per month. After the COVID-19 policy changes, there was an immediate increase of 265 patients in the first month, and the number continued to increase significantly, at a rate of 47 patients per month. The demographic characteristics of patients receiving buprenorphine during the pandemic period were similar to those during the pre-pandemic period, but the proportion of patients reaching 90-day retention on buprenorphine treatment decreased significantly from 49.6% to 47.7%, while days on buprenorphine increased significantly from 203.8 to 208.7.

CONCLUSIONS

The number of patients receiving buprenorphine continued to increase after the COVID-19 policy changes, but the delivery of care shifted to telehealth visits, suggesting that any reversal of COVID-19 policies must be carefully considered.

Perioperative Management of Buprenorphine/Naloxone in a Large, National Health Care System: a Retrospective Cohort Study

BACKGROUND

Medication for opioid use disorder, including buprenorphine and methadone, is considered the gold standard treatment for opioid use disorder (OUD). As the number of patients receiving buprenorphine has grown, clinicians increasingly care for patients prescribed buprenorphine who present for surgery and require management of perioperative pain.

OBJECTIVE

To describe practice patterns of perioperative and post-surgical use of buprenorphine among patients prescribed buprenorphine for OUD who experience major surgery.

DESIGN

Retrospective cohort study utilizing data from the VA Corporate Data Warehouse (CDW), a national repository of patient-level data. Data not accessible in CDW, including clinical instructions to patients to modify buprenorphine dose, were accessed via chart review.

PARTICIPANTS

National sample of patients receiving care through the Veterans Health Administration.

MAIN MEASURES

We report descriptive statistics on the incidence of buprenorphine dose hold prior to, during, and immediately following surgery, as well as post-surgical outcomes. Multivariable logistic regression identified socio-demographic and clinical characteristics associated with perioperative hold.

KEY RESULTS

Our final sample comprised 183 patients, the majority of whom were white and male. Most patients (66%) experienced a perioperative buprenorphine dose hold: during the pre-operative, day of surgery, and post-operative periods, 40%, 62%, and 55% of patients had buprenorphine held. Buprenorphine dose hold was less likely for patients who had experienced homelessness/housing insecurity in the year prior to surgery (aOR = 0.25; 95% CI 0.10-0.61) as well as patients residing in rural areas (aOR=0.29; 0.12-0.68). Within the 12-month period following surgery, 122 patients (67%) were retained on buprenorphine, 10 patients (5.5%) had experienced an overdose, and 15 (8.2%) had died.

CONCLUSIONS

We identified high rates of perioperative buprenorphine dose holds. As holding buprenorphine perioperatively does not align with emerging clinical recommendations and carries significant risks, educational campaigns or other provider-targeted interventions may be needed to ensure patients with OUD receive recommended care.

The introduction of a novel formulation of buprenorphine into organized health systems

Background

Effective medications for opioid use disorder (MOUD) are underutilized. This exploratory study used real-world data to analyze US distribution patterns of buprenorphine extended-release (BUP-XR) within organized health systems (OHS), including the Veterans Health Administration (VHA), Indian Health Service (IHS), criminal justice system (CJS), and integrated delivery networks (IDNs).

Methods

National BUP-XR distribution data within each OHS were available from WNS Global Services and were evaluated from July 2019 through July 2020. BUP-XR distribution data by OHS subtype (VHA, IHS, CJS, IDN) and state were aggregated and reported.

Results

The total distribution of BUP-XR increased from 6,721 units in the second half of 2019 (H2'19) to 12,925 in the first half of 2020 (H1'20). OHS distribution increased from H2'19 to H1'20 in every subtype but was primarily driven by IDN distribution growth. IDNs accounted for 73% of total units in H2'19 and continued to grow in H1'20. In H1'20, IDNs accounted for 78%, VHA for 12%, CJS for 6%, and IHS for 4%. IDN distribution for BUP-XR increased from 4,911 to 10,100 units, showing the highest growth rate of 106% within all OHS subtypes. The states with the highest total BUP-XR distribution over the 12-month period were Massachusetts (4,534), Pennsylvania (3,773), and California (1,866).

Conclusions

Overall distribution of BUP-XR, as a treatment option for OUD, is increasing; however, access to MOUD varies greatly across OHS subtypes and geography. Identifying and overcoming barriers to appropriate MOUD use is critical in addressing the opioid crisis.

Understanding opportunities and challenges with telemedicine-delivered buprenorphine during the COVID-19 pandemic

INTRODUCTION

Opioid use disorder (OUD) is a debilitating illness that remains a serious public health issue in the United States. Use of telemedicine to deliver medications for the treatment of OUD (MOUD) was limited until the confluence of the COVID-19 and opioid addiction epidemics in spring 2020. Starting in spring 2020, the Department of Veterans Health Affairs (VHA) transitioned from in-person to mostly telemedicine-delivered OUD care to reduce COVID-19 transmission among veterans and providers. To gain a nuanced understanding of provider perspectives on MOUD care delivery using telemedicine, we conducted semi-structured interviews with VHA providers who were using telehealth to deliver MOUD care.

METHODS

We conducted semi-structed Zoom interviews with VA clinicians at nine VA Medical Centers (VAMCs) in eight states. Potential study participants were identified as providers who were involved in referrals and provision of buprenorphine treatment for chronic pain and opioid addiction. Audio-recordings of all interviews were transcribed and entered into Atlas. Ti qualitative analysis software. The study team analyzed the transcripts for major themes related to tele-prescribing practices for buprenorphine.

RESULTS

Twenty-three VA providers participated in the study, representing 32% of all providers invited to participate in the study. The research team identified the following four themes: (1) COVID-19 spurred a seismic shift in OUD treatment; (2) Video calls provided a rare window into veterans' lives; (3) Providers experienced numerous challenges to virtual visits; and (4) Providers wrestled with paternalism and trust.

CONCLUSIONS

The pandemic accelerated the movement toward harm reduction approaches. Prior to the pandemic, stringent requirements existed for patients receiving MOUD care. Providers in this study reflected on the need for these requirements (e.g., in-person visits, toxicology screens) and how reducing this monitoring implied more trust in patients' autonomous decisions. Providers' observation that videoconferencing offered them a window into patients' lives may offer some ways to improve rapport, and research should explore how best to incorporate the additional information conveyed in virtual visits.

Association between clinically recognized suicidality and subsequent initiation or continuation of medications for opioid use disorder

BACKGROUND

Among individuals with opioid use disorder (OUD), medications for OUD (MOUD) may lower suicide risk. Therefore, it is important that individuals with OUD and suicidality receive MOUD. This study examined associations between clinically recognized suicidality and subsequent initiation or continuation of MOUD among patients with OUD in the national Veterans Health Administration (VA).

METHODS

Electronic health record data were extracted for outpatients with OUD who received VA care 10/1/2016-7/31/2017. Suicidality was measured using diagnostic codes for suicidal ideation/attempt and patient record flags. Analyses were conducted separately among patients without prior-year MOUD receipt to examine MOUD initiation, and with prior-year MOUD receipt to examine MOUD continuation. Poisson regression models estimated likelihood of MOUD receipt in the following year for patients with prior-year suicidality relative to those without. Models were adjusted for sociodemographic and clinical characteristics.

RESULTS

Among 20,085 patients with no prior-year MOUD, 12% had suicidality and 12% received MOUD in the following year. Suicidality was positively associated with MOUD initiation (adjusted incidence rate ratio [aIRR]: 1.15, 95% confidence interval [CI]: 1.04-1.28). Among 10,162 patients with prior-year MOUD, 9% had suicidality and 84% received MOUD in the following year. Suicidality was negatively associated with MOUD continuation (aIRR: 0.95, 95% CI 0.91-0.98).

CONCLUSIONS

Among VA patients with OUD, clinically recognized suicidality may increase likelihood of MOUD initiation but decrease likelihood of continuation. Efforts to increase initiation overall and to support retention for patients with suicidality are needed.

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.

Telehealth Utilization Is Associated with Lower Risk of Discontinuation of Buprenorphine: a Retrospective Cohort Study of US Veterans

OBJECTIVE

Treatment for opioid use disorder (OUD) may include a combination of pharmacotherapies (such as buprenorphine) with counseling services if clinically indicated. Medication management or engagement with in-person counseling services may be hindered by logistical and financial barriers. Telehealth may provide an alternative mechanism for continued engagement. This study aimed to evaluate the association between telehealth encounters and time to discontinuation of buprenorphine treatment when compared to traditional in-person visits and to evaluate potential effect modification by rural-urban designation and in-person and telehealth combination treatment.

METHODS

A retrospective cohort study of Veterans diagnosed with OUD and treated with buprenorphine across all facilities within the Veterans Health Administration (VHA) between 2008 and 2017. Exposures were telehealth and in-person encounters for substance use disorder (SUD) and mental health, treated as time-varying covariates. The primary outcome was treatment discontinuation, evaluated as 14 days of absence of medication from initiation through 1 year.

RESULTS

Compared to in-person encounters, treatment discontinuation was lower for telehealth for SUD (aHR: 0.69; 95%CI: 0.60, 0.78) and mental health (aHR: 0.69; 95%CI: 0.62, 0.76). There was no evidence of effect modification by rural-urban designation. Risk of treatment discontinuation appeared to be lower among those with telehealth only compared to in-person only for both SUD (aHR: 0.48, 95%CI: 0.37, 0.62) and for mental health (aHR: 0.46; 95%CI: 0.33, 0.65).

CONCLUSIONS

As telehealth demonstrated improved treatment retention compared to in-person visits, it may be a suitable option for engagement for patients in OUD management. Efforts to expand services may improve treatment retention and health outcomes for VHA and other health care systems.

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.

Twelve-Month Retention in Opioid Agonist Treatment for Opioid Use Disorder Among Patients With and Without HIV

Although opioid agonist therapy (OAT) is associated with positive health outcomes, including improved HIV management, long-term retention in OAT remains low among patients with opioid use disorder (OUD). Using data from the Veterans Aging Cohort Study (VACS), we identify variables independently associated with OAT retention overall and by HIV status. Among 7,334 patients with OUD, 13.7% initiated OAT, and 27.8% were retained 12-months later. Likelihood of initiation and retention did not vary by HIV status. Variables associated with improved likelihood of retention included receiving buprenorphine (relative to methadone), receiving both buprenorphine and methadone at some point over the 12-month period, or diagnosis of HCV. History of homelessness was associated with a lower likelihood of retention. Predictors of retention were largely distinct between patients with HIV and patients without HIV. Findings highlight the need for clinical, systems, and research initiatives to better understand and improve OAT retention.

Associations Among Military Sexual Trauma, Opioid Use Disorder, and Gender

INTRODUCTION

Opioid use disorder and high-risk opioid prescription increase the risks for overdose and death. In Veterans, military sexual trauma is associated with increased risk for assorted health conditions. This study evaluates the association of military sexual trauma with opioid use disorder and high-risk opioid prescription and potential moderation by gender.

METHODS

In a national sample of Veterans Health Administration outpatients receiving care from October 1, 2009 to August 1, 2017, logistic regression models were fit to evaluate the associations between military sexual trauma and opioid use disorder and high-risk opioid prescription, adjusting for demographic and clinical covariates. A second set of models included a gender X military sexual trauma interaction. Analyses were conducted in 2020-2021.

RESULTS

Patients with history of military sexual trauma (n=327,193) had 50% higher odds of opioid use disorder diagnosis (AOR=1.50, 95% CI=1.45, 1.54, p<0.001) and 5% higher odds of high-risk opioid prescription (AOR=1.05, 95% CI=1.04, 1.07, p<0.001) than those without history of military sexual trauma (n=7,738,665). The effect of military sexual trauma on opioid use disorder was stronger in men than in women . The predicted probability of opioid use disorder among men with history of military sexual trauma (1.5%) was nearly double that of women with history of military sexual trauma (0.8%).

CONCLUSIONS

Military sexual trauma was a significant risk factor for opioid use disorder and high-risk opioid prescription, with the former association particularly strong in men. Clinical care for Veterans with military sexual trauma should consider elevated risk of opioid use disorder and high-risk opioid prescription.

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.

Rationale, design and methods of VA-BRAVE: a randomized comparative effectiveness trial of two formulations of buprenorphine for treatment of opioid use disorder in veterans

Background

To address the US opioid epidemic, there is an urgent clinical need to provide persons with opioid use disorder (OUD) with effective medication treatments for OUD (MOUD). Formulations of sublingual buprenorphine/naloxone (SL-BUP/NLX) are considered the standard of care for OUD including within the Veterans Healthcare Administration (VHA). However, poor retention on MOUD undermines its effectiveness. Long-acting injectable monthly buprenorphine (INJ-BUP) (e.g., Sublocade®) has the potential to improve retention and therefore reduce opioid use and overdose. Designing and conducting studies for OUD pose unique challenges. The strategies and solutions to some of these considerations in designing Cooperative Studies Program (CSP) 2014, Buprenorphine for Treating Opioid Use Disorder in Veterans (VA-BRAVE), a randomized, 20-site, clinical effectiveness trial comparing INJ-BUP to SL-BUP/NLX conducted within the VHA may provide valuable guidance for others confronted with similar investigation challenges.

Methods

This 52-week, parallel group, open-label, randomized controlled trial (RCT) evaluates the comparative effectiveness of two current FDA-approved formulations of buprenorphine: (1) daily SL-BUP/NLX vs. (2) monthly (28-day) INJ-BUP for Veterans with moderate to severe OUD (n = 952). The primary outcomes are (1) retention in MOUD and (2) opioid abstinence. Secondary outcomes include measures of other drug use, psychiatric symptoms, medical outcomes including prevalence rates of HIV, hepatitis B and C as well as social outcomes (housing instability, criminal justice involvement), service utilization and cost-effectiveness. Special considerations in conducting a comparative effectiveness trial with this population and during COVID-19 pandemic were also included.

Discussion

The evaluation of the extended-release formulation of buprenorphine compared to the standard sublingual formulation in real-world VHA settings is of paramount importance in addressing the opioid epidemic. The extent to which this new treatment facilitates retention, decreases opioid use, and prevents severe sequelae of OUD has not been studied in any long-term trial to date. Positive findings in this trial could lead to widespread adoption of MOUD, and, if proven superior INJ-BUP, by clinicians throughout the VHA and beyond. This treatment has the potential to reduce opioid use among Veterans, improve medical, psychological, and social outcomes, and save lives at justifiable cost.

Using data science to improve outcomes for persons with opioid use disorder

Medication treatment for opioid use disorder (MOUD) is an effective evidence-based therapy for decreasing opioid-related adverse outcomes. Effective strategies for retaining persons on MOUD, an essential step to improving outcomes, are needed as roughly half of all persons initiating MOUD discontinue within a year. Data science may be valuable and promising for improving MOUD retention by using "big data" (e.g., electronic health record data, claims data mobile/sensor data, social media data) and specific machine learning techniques (e.g., predictive modeling, natural language processing, reinforcement learning) to individualize patient care. Maximizing the utility of data science to improve MOUD retention requires a three-pronged approach: (1) increasing funding for data science research for OUD, (2) integrating data from multiple sources including treatment for OUD and general medical care as well as data not specific to medical care (e.g., mobile, sensor, and social media data), and (3) applying multiple data science approaches with integrated big data to provide insights and optimize advances in the OUD and overall addiction fields.
