Primary Care-Based Models for the Treatment of Opioid Use Disorder: A Scoping Review

Assessing the needs of front-line providers in addressing the opioid crisis in South Carolina

Opioid use disorder (OUD) has been declared a national crisis, as prevalence of OUD has increased remarkably over the past decade (Jones, 2017). While Medication Assisted Treatment (MAT) is the standard of care for OUDs, several key barriers to implementation have been noted throughout the clinical and research literature (DeFlavio et al., 2015). As a first step toward enhancing implementation and dissemination of MAT across the state of South Carolina, a needs assessment was conducted with key persons from 33 agencies to inform our efforts. Results provided descriptive information regarding medical providers and patients seen within agencies. Of the 33 agencies, 6 agencies (18%) reported having buprenorphine-waivered providers on staff (total of 11 medical providers across the 6 agencies). Agencies reported that they referred a mean of 4.63 patients to other facilities for MAT in the past month. Barriers to providing MAT were identified, with the most significant barrier including the lack of medical staff to prescribe buprenorphine (47%). Overall, the current study reiterates the gap between treatment need and capacity for OUD patients, and highlights factors associated with barriers to MAT adoption in state-funded county drug and alcohol agencies across a southern, predominantly rural state.

Statewide collaborative partnerships among American Indian and Alaska Native (AI/AN) communities in California to target the opioid epidemic: Preliminary results of the Tribal Medication Assisted Treatment (MAT) key informant needs assessment

American Indian and Alaska Native (AI/AN) communities have disproportionately been impacted by the opioid epidemic with the second highest opioid-related overdose death rates compared to other ethnic groups. The diversity among California AI/AN tribes, including regional differences in economic opportunities, tribal affiliation and organization, resources and infrastructure, requires a strong community-based partnership approach to assess global statewide patterns in service availability, acceptability, and utilization, as well as capturing the unique challenges and service needs within each region. This article describes a statewide community-based needs assessment of strengths and weakness among key informants in CA to identify facilitators and barriers to treatment of substance use disorders (SUD) and opioid use disorders (OUD). We conducted structured interviews of 21 healthcare professionals from Urban Indian Health Programs, Tribal clinics and community-based organizations throughout California. The interview assessed (1) barriers to accessing services; (2) risk factors; (3) protective factors; (4) community substance use description; (5) SUD and OUD services available; and (6) service system needs. Findings indicate an overall increase in SUD and OUD in AI/AN communities. Key informants discussed the importance of comprehensive and culturally centered care, wrap-around services, such as treatment of mental health issues alongside substance abuse, and the need for AI/AN-specific treatment facilities that integrate traditional and cultural activities into western health services.

The Washington State Hub and Spoke Model to increase access to medication treatment for opioid use disorders

INTRODUCTION

The federal Opioid State Targeted Response (Opioid STR) grants provided funding to each state to ramp up the range of responses to reverse the ongoing opioid crisis in the U.S. Washington State used these funds to develop and implement an integrated care model to expand access to medication treatment and reduce unmet need for people with opioid use disorders (OUD), regardless of how they enter the treatment system. This paper examines the design, early implementation and results of the Washington State Hub and Spoke Model.

METHODS

Descriptive data were gathered from key informants, document review, and aggregate data reported by hubs and spokes to Washington State's Opioid STR team.

RESULTS

The Washington State Hub and Spoke Model reflects a flexible approach that incorporates primary care and substance use treatment programs, as well as outreach, referral and social service organizations, and a nurse care manager. Hubs could be any type of program that had the required expertise and capacity to lead their network in medication treatment for OUD, including all three FDA-approved medications. Six hub-spoke networks were funded, with 8 unique agencies on average, and multiple sites. About 150 prescribers are in these networks (25 on average). In the first 18 months, nearly 5000 people were inducted onto OUD medication treatment: 73% on buprenorphine, 19% on methadone, and 9% on naltrexone.

CONCLUSIONS

The Washington State Hub and Spoke Model built on prior approaches to improve the delivery system for OUD medication treatment and support services, by increasing integration of care, ensuring "no wrong door," engaging with community agencies, and supporting providers who are offering medication treatment. It used essential elements from existing integrated care OUD treatment models, but allowed for organic restructuring to meet the population needs within a community. To date, there have been challenges and successes, but with this approach, Washington State has provided medication treatment for OUD to nearly 5000 people. Sustainability efforts are underway. In the face of the ongoing opioid crisis, it remains essential to develop, implement and evaluate novel models, such as Washington's Hub and Spoke approach, to improve treatment access and increase capacity.

Engagement With Project ECHO to Increase Medication-Assisted Treatment in Rural Primary Care

OBJECTIVE

The purpose of this study was to understand the barriers and facilitators that affect engagement with Project ECHO (Extension for Community Healthcare Outcomes) to implement medication-assisted treatment (MAT) in primary care settings.

METHODS

A 12-session weekly curriculum was delivered to participating primary care providers and clinic staff (N=24 participants from 13 clinics). Participants completed attendance logs and a qualitative interview in order to identify factors that influence engagement in the ECHO sessions and the potential integration of MAT.

RESULTS

Primary care providers and staff valued the ECHO sessions, but overall attendance was low and variable. Participants generally valued the didactic and interactive nature of the sessions but identified system-level constraints that limited engagement. Major barriers to participation included competing demands in patient care and the low degree of endorsement by clinic leadership.

CONCLUSIONS

This brief report identifies key systematic challenges that may directly limit primary care providers' engagement in telementoring models such as Project ECHO.

Screening for Substance Use in Rural Primary Care: a Qualitative Study of Providers and Patients

BACKGROUND

Substance use frequently goes undetected in primary care. Though barriers to implementing systematic screening for alcohol and drug use have been examined in urban settings, less is known about screening in rural primary care.

OBJECTIVE

To identify current screening practices, barriers, facilitators, and recommendations for the implementation of substance use screening in rural federally qualified health centers (FQHCs).

DESIGN

As part of a multi-phase study implementing electronic health record-integrated screening, focus groups (n = 60: all stakeholder groups) and individual interviews (n = 10 primary care providers (PCPs)) were conducted.

PARTICIPANTS

Three stakeholder groups (PCPs, medical assistants (MAs), and patients) at three rural FQHCs in Maine.

APPROACH

Focus groups and interviews were recorded, transcribed, and content analyzed. Themes surrounding current substance use screening practices, barriers to screening, and recommendations for implementation were identified and organized by the Knowledge to Action (KTA) Framework.

KEY RESULTS

Identifying the problem: Stakeholders unanimously agreed that screening is important, and that universal screening is preferred to targeted approaches. Adapting to the local context: PCPs and MAs agreed that screening should be done annually. Views were mixed regarding the delivery of screening; patients preferred self-administered, tablet-based screening, while MAs and PCPs were divided between self-administered and face-to-face approaches. Assessing barriers: For patients, barriers to screening centered around a perceived lack of rapport with providers, which contributed to concerns about trust, judgment, and privacy. For PCPs and MAs, barriers included lack of comfort, training, and preparedness to address screening results and offer treatment.

CONCLUSIONS

Though stakeholders agree on the importance of implementing universal screening, concerns about the patient-provider relationship, the consequences of disclosure, and privacy appear heightened by the rural context. Findings highlight that strong relationships with providers are critical for patients, while in-clinic resources and training are needed to increase provider comfort and preparedness to address substance use.

Evidence for state, community and systems-level prevention strategies to address the opioid crisis

BACKGROUND

Practitioners and policy makers need evidence to facilitate the selection of effective prevention interventions that can address the ongoing opioid overdose epidemic in the United States.

METHODS

We conducted a systematic review of publications reporting on rigorous evaluations of systems-level interventions to address provider and patient/public behavior and prevent prescription and illicit opioid overdose. A total of 251 studies were reviewed. Interventions studied included 1) state legislation and regulation, 2) prescription drug monitoring programs (PDMPs), 3) insurance strategies, 4) clinical guideline implementation, 5) provider education, 6) health system interventions, 7) naloxone education and distribution, 8) safe storage and disposal, 9) public education, 10) community coalitions, and 11) interventions employing public safety and public health collaborations.

RESULTS

The quality of evidence supporting selected interventions was low to moderate. Interventions with the strongest evidence include PDMP and pain clinic legislation, insurance strategies, motivational interviewing in clinical settings, feedback to providers on opioid prescribing behavior, intensive school and family-based programs, and patient education in the clinical setting.

CONCLUSIONS

Although evidence is growing, further high-quality research is needed. Investigators should aim to identify strategies that can prevent overdose, as well as influence public, patient, and provider behavior. Identifying which strategies are most effective at addressing prescription compared to illicit opioid misuse and overdose could be fruitful, as well as investigating synergistic effects and unintended consequences.

Responding to the opioid and overdose crisis with innovative services: The recovery community center office-based opioid treatment (RCC-OBOT) model

Opioid use disorder (OUD) and opioid-related overdose mortality are major public health concerns in the United States. Recently, several community-based and professional innovations - including hybrid recovery community organizations, peer-based emergency department warm handoff programs, emergency department buprenorphine induction, and low-threshold OUD treatment programs - have emerged or expanded in an effort to address significant obstacles to providing patients the care needed for OUD and to reduce the risk of overdose. Additional innovations are needed to address the crisis. Building upon the foundational frameworks of each of these recent innovations, a new model of OUD pharmacotherapy is proposed and discussed: the Recovery Community Center Office-Based Opioid Treatment model. Additionally, two potential implementation scenarios, the overdose and non-overdose event protocols, are detailed for communities, peers, and practitioners interested in implementing the model. Potential barriers to implementation of the model include service reimbursement, licensing regulations, and organizational concerns. Future research should seek to validate the model and to identify actual implementation and sustainability barriers and best practices.

Unmet mental health and substance use treatment needs among older homeless adults: Results from the HOPE HOME Study

AIMS

To examine the prevalence of and factors associated with unmet need for mental health and substance use treatment in older homeless adults.

METHODS

Among 350 homeless adults aged ≥50, we examined prevalence of mental health and substance use problems and treatment. Using logistic regression, we examined factors associated with unmet treatment need.

RESULTS

Among those with a mental health problem, being aged ≥65 was associated with an increased odds, while having a regular healthcare provider and case manager were associated with a decreased odds of having unmet need for mental health treatment. A first homelessness episode at age ≥50 was associated with increased, while spending time in jail/prison or having a case manager was associated with decreased odds of unmet needs for substance use treatment.

CONCLUSION

Older homeless adults have a high prevalence of unmet behavioral health treatment need. There is a need for targeted services for this population.

Applying and advancing best practices in opioid use disorder and addiction treatment: Introduction to the special issue on implementation science and quality improvement scholarship

To help realize the promise of evidence-based practices to stem the opioid crisis, there is a glaring need for descriptions of how practices are effectively disseminated and implemented. Unfortunately, addiction journals do not often publish addiction implementation science and non-research descriptions of quality improvement projects. This is unfortunate as these projects are more representative of how research is translated into practice in the real-world and offer guidance and practical information to help speed implementation of evidence-based practices. To support translation of research into practice, primary, secondary, and tertiary intervention implementation science and quality improvement projects should be disseminated. We are excited to again partner with the Providers' Clinical Support System for Opioid Therapies in presenting implementation and quality improvement demonstration projects in this special issue: "Implementation and Quality Improvement: Applying and Advancing Best Practices in Opioid Use Disorder and Addiction Treatment."

A comparison of buprenorphine and psychosocial treatment outcomes in psychosocial and medical settings

BACKGROUND

Facing an epidemic of opioid-related mortality, many government health departments, insurers, and treatment providers have attempted to expand patient access to buprenorphine in psychosocial substance use disorder (SUD) programs and medical settings.

METHODS

With Missouri Medicaid data from 2008 to 2015, we used Cox proportional hazard models to estimate the relative hazards for treatment attrition and SUD-related emergency department (ED) visits or hospitalizations associated with buprenorphine in psychosocial SUD programs and medical settings. We also tested the association of buprenorphine with hours of psychosocial treatment during the first 30 days of psychosocial SUD treatment. The analytic sample included claims from 7606 individuals with an OUD diagnosis.

RESULTS

Compared to psychosocial treatment without buprenorphine (PSY), the addition of buprenorphine (PSY-B) was associated with a significantly reduced hazard for treatment attrition (adjusted hazard ratio: 0.67, 95% CI: 0.62-0.71). Among buprenorphine episodes, office-based (B-OBOT), outpatient hospital (B-OPH), and no documented setting (B-PHA) were associated with reduced hazards for treatment attrition when compared to the psychosocial SUD setting (B-PSY) (adjusted hazard ratios: 0.27, 95% CI: 0.24-0.31; 0.46, 95% CI: 0.39-0.54; 0.70, 95% CI: 0.61-0.81). Compared to B-PSY, B-OBOT and B-PHA were associated with significantly reduced hazards for a SUD-related ED visits or hospitalization (adjusted hazard ratios: 0.59, 95% CI: 0.41-0.85; 0.53, 95% CI: 0.36-0.78). There was no significant difference between B-PSY and B-OPH or B-PSY and PSY in hazard for an SUD-related ED visit or hospitalization.

CONCLUSIONS

Our findings support the conclusion that adding buprenorphine to Medicaid-covered psychosocial SUD treatment reduces patient attrition and SUD-related ED visits or hospitalizations but that buprenorphine treatment in office-based medical settings is even more effective in reducing these negative outcomes. Policy-makers should consider ways to expand buprenorphine access in all settings, but particularly in office-based medical settings. Buprenorphine treatment in an unbilled setting was associated with an increased hazard for patient attrition when compared to treatment in billed medical settings, indicating the importance of Medicaid-covered provider visits for patient retention.

Treating opioid dependence with extended-release naltrexone (XR-NTX) in Ukraine: Feasibility and three-month outcomes

BACKGROUND

Although opioid agonist treatments (OAT) with methadone or buprenorphine are available to treat opioid use disorders (OUD) in Ukraine, OAT acceptability and coverage remains low. Extended-release naltrexone (XR-NTX) that recently became available as another treatment option provides new opportunities for treating OUDs in this region and we aimed to test its feasibility.

METHODS

Patients with OUD (N=135) and interested in treatment with XR-NTX were initiated on monthly XR-NTX injections and monitored for three months. Correlates of 3-month retention on XR-NTX and drug use at each time-point using self-reports and urine drug testing (UDT) were assessed.

RESULTS

Of the 134 participants initiated XR-NTX, 101 (75%) completed three months, defined as 4 consecutive XR-NTX injections. Independent factors negatively associated with retention in XR-NTX treatment included previous maintenance with OAT (aOR=0.3; 95%CI=0.1-0.9) and extrinsic help-seeking treatment motivation (aOR=0.7; 95%CI=0.5-0.9). Of these 101 participants completing three months of treatment, opioid use markedly reduced using self-report (67%% to 22%; p>0.001) and UDT (77% to 24%; p<0.001) outcomes over time. Alcohol, marijuana and stimulant use, however, remained unchanged. Craving for opioids and symptoms of depression also significantly decreased, while health-related quality of life scores improved over time. No adverse side effects were reported during the period of observation.

CONCLUSION

The first introduction of XR-NTX in Ukraine among persons with OUD resulted in high levels of retention, marked reductions in opioid use and improved quality of life. These descriptive results suggest that XR-NTX treatment is feasible and well-tolerated over a 3-month period in Ukraine.

Predictors of Medication-Assisted Treatment Initiation for Opioid Use Disorder in an Interdisciplinary Primary Care Model

INTRODUCTION

Medication-assisted treatment (MAT) for opioid use disorder (OUD) is underused in primary care. Little is known about patient demographics associated with MAT initiation, particularly among models with an interdisciplinary approach, including behavioral health integration. We hypothesize few disparities in MAT initiation by patient characteristics after implementing this model for OUD.

METHODS

Electronic health record data were used to identify adults with ≥1 primary care visit in 1 of 2 study clinics in a Pacific Northwest academic health system between September 1, 2015 and August 31, 2017 (n = 23,372). Rates of documented OUD diagnosis were calculated. Multivariate logistic regression estimated odds ratios of MAT initiation, defined as ≥1 electronic health record order for buprenorphine or naltrexone, by patient covariates.

RESULTS

Seven percent of the study sample had an OUD diagnosis. Of those patients, 32% had ≥1 MAT order. Patients with documented psychiatric diagnoses or tobacco use had higher odds of initiating MAT (odds ratio [OR] = 1.62, P = .0003; OR = 2.46, P < .0001, respectively). Uninsured, Medicaid, and Medicare patients had lower odds than those commercially insured (OR = 0.53, 0.38, and 0.31, respectively; P < .0001). Patients who were older, of a race/ethnicity other than non-Hispanic white, had documented diabetes, and had documented asthma or chronic obstructive pulmonary disease showed lower odds of initiation.

DISCUSSION

MAT initiation varied by patient characteristics, including disparities by insurance coverage and race/ethnicity. The addition of behavioral health did not eliminate disparities in care, but higher odds of initiation among those with a documented psychiatric diagnosis may suggest this model reaches some vulnerable populations. Additional research is needed to further examine these findings.

Multi-model implementation of evidence-based care in the treatment of opioid use disorder in Pennsylvania

Pennsylvania has the third highest rate of death due to drug overdose (44.3 per 100,000) in the country, which is significantly higher than the national rate. This continues to have drastic societal impact. Medication assisted treatment (MAT), which includes opioid agonist medications, is the gold standard in treatment for OUD; however, a significant gap remains between the number of individuals in need of treatment and the number of MAT providers. Penn State Health established a system to address the opioid epidemic through the Pennsylvania Coordinated Medication Assisted Treatment program utilizing lessons learned from existing validated models. Connecting primary care sites and hospital systems through a combination of Hub and Spoke, bridge clinic services provided at the Hub, peer recovery services, Project Extension for Community Health Outcomes (ECHO), and layered emergency department (ED) initiation of buprenorphine, this model is an innovative approach that addresses many known barriers to MAT treatment initiation. Early results within the first six months indicate significantly shortened wait time for patients seeking treatment, provision of waiver training to 70 local physicians to prescribe buprenorphine, and improved knowledge and ability to provide patient care for providers participating in our first Project ECHO cohort.

Measurement-based care using DSM-5 for opioid use disorder: can we make opioid medication treatment more effective?

CONTEXT AND PURPOSE

Measurement-based care (MBC) is an evidence-based health-care practice in which indicators of disease are tracked to inform clinical actions, provide feedback to patients and improve outcomes. The current opioid crisis in multiple countries provides a pressing rationale for adopting a basic MBC approach for opioid use disorder (OUD) using DSM-5 to increase treatment retention and effectiveness.

PROPOSAL

To stimulate debate, we propose a basic MBC approach using the 11 symptoms of OUD (DSM-5) to inform the delivery of medications for opioid use disorder (MOUD; including methadone, buprenorphine and naltrexone) and their evaluation in office-based primary care and specialist clinics. Key features of a basic MBC approach for OUD using DSM-5 are described, with an illustration of how clinical actions are guided and outcomes communicated. For core treatment tasks, we propose that craving and drug use response to MOUD should be assessed after 2 weeks, and OUD remission status should be evaluated at 3, 6 and 12 months (and exit from MOUD treatment) and beyond. Each of the 11 DSM-5 symptoms of OUD should be discussed with the patient to develop a case formulation and guide selection of adjunctive psychological interventions, supplemented with information on substance use, and optionally extended with information from other clinical instruments. A patient-reported outcome measure should be recorded and discussed at each remission assessment.

CONCLUSIONS

MBC can be used to tailor and adapt MOUD treatment to increase engagement, retention and effectiveness. MBC practice principles can help promote patient-centred care in OUD, personalized addiction therapeutics and facilitate communication of outcomes.

Implementation of the hub and spoke model for opioid use disorders in California: Rationale, design and anticipated impact

As part of the State Targeted Response to the opioid epidemic, California has adopted the Hub and Spoke model to expand access to medications for opioid use disorder, particularly buprenorphine, throughout the state. By aligning opioid treatment programs as hubs with primary care, office-based practitioners, and other health care settings as spokes, a broader treatment model can reach more people with opioid use disorder, improve access to medications for opioid use disorders, and decrease overdose deaths. Expanding access requires expanding knowledge and intensive implementation support of new practices. This paper describes the rationale, specific activities and anticipated impact of the implementation plan in California's Hub and Spoke system. Training and technical assistance are designed to: increase the number and capacity of waivered prescribers; enhance skills of prescribers and multidisciplinary teams; and create systems change. Activities include buprenorphine waiver trainings and provider support, a practice facilitator program, Project ECHO sessions, webinars, clinical skills trainings, and regional learning collaboratives. This overview highlights the steps California is taking to build treatment capacity to address the opioid epidemic.

Barriers to Buprenorphine Expansion in Ohio: A Time-Elapsed Qualitative Study

Buprenorphine partial opioid agonist pharmacotherapy, a key treatment for opioid use disorders (OUDs), is underutilized in the United States. Qualitative interviews, conducted in 2012/2013 and repeated in 2015, identified systemic barriers to providing buprenorphine treatment in Ohio. A representative sample of Ohio's Alcohol, Drug Abuse and Mental Health Services (ADAMHS) county boards (n = 18) was selected based on percentage of OUD admissions, density of buprenorphine prescribers, and county board area population. Boards reported that the barriers to the use of buprenorphine in 2012/2013 included (1) negative attitudes toward the use of buprenorphine among substance use disorder treatment providers; (2) a lack of prescribers; and (3) lack of funding. The 2015 interviews suggested that the lack of prescribers surpassed lack of funding as the main impediment to buprenorphine expansion. Negative provider attitudes were no longer problematic. Concerns about buprenorphine diversion, however, had emerged as a new barrier. This article offers recommendations for future policy efforts to overcome these barriers and expand the use of evidence-based opioid treatments. It highlights the need for payers and policymakers to increase the number of buprenorphine prescribers to make best use of funding available to fight the opioid epidemic.

Implementation and evaluation of Missouri's Medication First treatment approach for opioid use disorder in publicly-funded substance use treatment programs

BACKGROUND

Leaders of Missouri's State Targeted Response to the opioid crisis (STR) grant have prioritized increasing access to treatment medications for opioid use disorder (MOUD) through a "Medication First" approach. This conceptual framework prioritizes rapid, sustained, low-barrier access to MOUD for optimal impact on decreased illicit drug use and mortality. Medication First principles and practices were facilitated through state-level structural changes and disseminated to participating community treatment programs via a multi-pronged, multi-disciplinary approach. In the first nine months of STR, 14 state-contracted treatment agencies operating 38 sites used STR funding to implement the Medication First model.

METHODS

We utilized state billing and service data to make comparisons before and during STR on the following outcomes: MOUD utilization, timely access to MOUD, amount of psychosocial services delivered, treatment retention at 1, 3, and 6 months, and monthly price of treatment. We conducted follow-up analyses examining differences across MOUD types (no medication, methadone, buprenorphine, oral naltrexone, mixed antagonist + agonist, and extended release naltrexone).

RESULTS

During STR, MOUD utilization increased (44.8% to 85.3%), timeliness of MOUD receipt improved (Median of 8 days vs. 0 days), there were fewer psychosocial services delivered, treatment retention improved at one, three, and six month timeframes, and the median cost per month was 21% lower than in the year prior to STR. All differences were driven by increased utilization of buprenorphine.

CONCLUSIONS

Findings suggest Medication First implementation through STR was successful in all targeted domains. Though much more work is needed to further reduce logistical, financial, and cultural barriers to improved access to maintenance MOUD, the steps taken through Missouri's STR grant show significant promise at making swift and drastic transformations to a system of care in response to a growing public health emergency.

Systematic Analysis of the Service Process and the Legislative and Regulatory Environment for a Pharmacist-Provided Naltrexone Injection Service in Wisconsin

Community pharmacists are viewed by the public as convenient and trustworthy sources of healthcare and pharmacists likely can play a larger role in addressing the major public health issue of the opioid epidemic affecting Wisconsin residents. Approved medications, including long-acting injectable naltrexone, can transform the treatment of individuals with opioid use disorder (OUD). Due to shortages of behavioral health providers in the U.S., and pharmacists' knowledge about the safe use of medications, pharmacists can be a significant access point for treating OUD with naltrexone. Wisconsin's pharmacy practice laws authorize pharmacists to administer medications via injection, and a small number of pharmacists currently are using this authority to provide a naltrexone injection service. This exploratory study had two objectives: (1) describe the pharmacist injection service process and identify barriers and facilitators to that service and (2) analyze the legislative/regulatory environment to ascertain support for expanding naltrexone injection service. Semi-structured pharmacist interviews (n = 4), and an analysis of Wisconsin statutes/regulations governing public health and social services, were undertaken to explore the objectives. Findings suggest that the service process requires considerable coordination and communication with practitioners, patients, and pharmacy staff, but many opportunities exist to broaden and sustain the service throughout Wisconsin.

Methadone Matters: What the United States Can Learn from the Global Effort to Treat Opioid Addiction

In the midst of an opioid epidemic, mortality related to opioid overdose continues to rise in the US. Medications to treat opioid use disorder, including methadone and buprenorphine, are highly effective in reducing the morbidity and mortality related to illicit opioid use. Despite the efficacy of these life-saving medications, the majority of people with an opioid use disorder lack access to treatment. This paper briefly reviews the evidence to support the use of medications to treat opioid use disorder with a specific focus on methadone. We discuss the current state of methadone therapy for the treatment of opioid use disorder in the US and present logistical barriers that limit its use. Next, we examine three international pharmacy-based models in which methadone dispensing to treat opioid use disorder occurs outside of an opioid treatment facility. We discuss current challenges and opportunities to incorporate similar methods of methadone dispensing for the treatment of opioid use disorder in the US. Finally, we present our vision to integrate pharmacy-based methadone dispensing into routine opioid use disorder treatment through collaboration between clinicians and pharmacies to improve local access to this life-saving medication.

U.S. National 90-Day Readmissions After Opioid Overdose Discharge

INTRODUCTION

U.S. hospital discharges for opioid overdose increased substantially during the past two decades. This brief report describes 90-day readmissions among patients discharged from inpatient stays for opioid overdose.

METHODS

In 2018, survey-weighted analysis of hospital stays in the 2016 Healthcare Cost and Utilization Project National Readmissions Database yielded the national estimated proportion of patients with opioid overdose stays that had all-cause readmissions within ≤90 days. A multivariable logistic regression model assessed index stay factors associated with readmission by type (opioid overdose or not). Number of readmissions per patient was assessed.

RESULTS

More than 24% (n=14,351/58,850) of patients with non-fatal index stays for opioid overdose had at least one all-cause readmission ≤90 days of index stay discharge and 3% (n=1,658/58,850) of patients had at least one opioid overdose readmission. Less than 0.2% (n=104/58,850) of patients had more than one readmission for opioid overdose. Patient demographic characteristics (e.g., male, older age), comorbidities diagnosed during the index stay (e.g., drug use disorder, chronic pulmonary disease, psychoses), and other index stay factors (Medicare or Medicaid primary payer, discharge against medical advice) were significantly associated with both opioid overdose and non-opioid overdose readmissions. Nearly 30% of index stays for opioid overdose included heroin, which was significantly associated with opioid overdose readmissions.

CONCLUSIONS

A quarter of opioid overdose patients have ≤90 days all-cause readmissions, although opioid overdose readmission is uncommon. Effective strategies to reduce readmissions will address substance use disorder as well as comorbid physical and mental health conditions.

Integrated Models of Care for Individuals with Opioid Use Disorder: How Do We Prevent HIV and HCV?

Purpose of Review

To describe models of integrated and co-located care for opioid use disorder (OUD), hepatitis C (HCV), and HIV.

Recent Findings

The design and scale-up of multidisciplinary care models that engage, retain, and treat individuals with HIV, HCV, and OUD are critical to preventing continued spread of HIV and HCV. We identified 17 models within primary care (N = 3), HIV specialty care (N = 5), opioid treatment programs (N = 6), transitional clinics (N = 2), and community-based harm reduction programs (N = 1), as well as two emerging models.

Summary

Key components of such models are the provision of (1) medication-assisted treatment for OUD, (2) HIV and HCV treatment, (3) HIV pre-exposure prophylaxis, and (4) behavioral health services. Research is needed to understand differences in effectiveness between co-located and fully integrated care, combat the deleterious racial and ethnic legacies of the “War on Drugs,” and inform the delivery of psychiatric care. Increased access to harm reduction services is crucial.

Comparing Buprenorphine-Prescribing Physicians Across Nonmetropolitan and Metropolitan Areas in the United States

PURPOSE

Although there is a tremendous need to increase the use of buprenorphine for the treatment of opioid use disorder in rural areas, little is known about current rural/urban differences in treatment practices. We aimed to examine physician characteristics, treatment practices, and concordance with treatment guidelines among buprenorphine prescribers across different locations of practice.

METHODS

A national random sample of buprenorphine physician prescribers was surveyed (n = 1,174, response rate = 33%) from July 2014 to January 2017. Analyses examined buprenorphine treatment across locations of practice (categorized as nonmetropolitan, small metropolitan, and large metropolitan).

RESULTS

Among buprenorphine prescribers surveyed, 11.2% (n = 132) practiced in nonmetropolitan/rural areas, 32.5% (n = 382) in small metropolitan areas, and 56.2% (n = 660) in large metropolitan areas. Buprenorphine prescribers in nonmetropolitan areas were much more likely to be primary care physicians, accept Medicaid, and less likely to work in an individual practice. Overall, buprenorphine prescribers across the rural/urban continuum were similar in many of their treatment practices, including induction, frequency of visits, dosing, and use of psychosocial treatment, which were generally consistent with buprenorphine treatment recommendations.

CONCLUSIONS

There are important differences in characteristics of buprenorphine prescribers in nonmetropolitan areas compared with more urban areas, including the fact that the majority of nonmetropolitan physicians are primary care physicians. Although treatment access in rural areas is an ongoing challenge, buprenorphine treatment practices are similar. Understanding buprenorphine prescribers and their treatment practices may help inform tailored strategies to address treatment needs in different locations.

The payer's role in addressing the opioid epidemic: It's more than money

BACKGROUND AND OBJECTIVE

County, State, and Federal agencies are addressing the public health opioid crisis. Ohio's 51 county-based Alcohol, Drug Addiction and Mental Health Services (ADAMHS) Boards finance and regulate opioid treatment services within their jurisdictions. This three-year comparative trial collaborated with ADAMHS Boards (n = 14) to test the Advancing Recovery Framework, a suite of organizational and system change strategies designed to promote use of buprenorphine for opioid agonist therapy.

METHODS

A multi-level intervention directed payers and treatment agencies to leverage their roles in increasing the use of buprenorphine. Half of the boards partnered with local substance use disorder treatment providers using the partnership strategies recommended by the Advancing Recovery (AR) framework. The comparison boards did not use the partnership strategies.

RESULTS AND CONCLUSION

A logistic regression analysis detected increases in the number of patients receiving buprenorphine in both conditions. Buprenorphine use, as a percentage of patients with an opioid use disorder diagnosis, was significantly greater among the boards using the Advancing Recovery strategies during the three-year experimental period (odds ratio (OR) 1.63, 95% CI, 1.50 to 1.76, p < .001) and a one-year maintenance period (OR 2.13, 95% CI, 1.85 to 2.46, p < .001). Boards in both groups provided similar levels of financial support to implement and maintain buprenorphine prescribing. Strategy differences between the study conditions existed in use of a committee that facilitated payer-provider partnering and the ADAMHS boards setting expectations for using buprenorphine. Payer-provider partnerships achieved greater improvements and maximized the effectiveness of funding in increasing access to buprenorphine.

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

The US Department of Veterans Affairs (VA), the largest health care system in the US, has been confronted with the health care consequences of opioid disorder (OUD). Increasing access to quality OUD treatment, including pharmacotherapy, is a priority for the VA. We examine the history of medications (e.g., methadone, buprenorphine, injectable naltrexone) used in the treatment of OUD within VA, document early and ongoing efforts to increase access and build capacity, primarily through the use of buprenorphine, and summarize research examining barriers and facilitators to prescribing and medication receipt. We find that there has been a slow but steady increase in the use of medications for OUD and, despite system-wide mandates and directives, uneven uptake across VA facilities and within patient sub-populations, including some of those most vulnerable. We conclude with recommendations intended to support the greater use of medication for OUD in the future, both within VA as well as other large health care systems.

The role of social work in the opioid epidemic: office-based opioid treatment programs

The opioid epidemic is a national emergency in the United States. To meet the needs of individuals diagnosed with Opioid Use Disorder (OUD) office-based opioid treatment programs (OBOT) are quickly expanding. However, social workers roles in OBOT programs are not clearly described. This paper will emphasize three roles social workers may fulfill in OBOT programs to combat the opioid crisis.

Characteristics and behavioral health needs of patients with patterns of high hospital use: implications for primary care providers

Background

A small percentage of patients relies extensively on hospital-based care and account for a disproportionately high share of health care spending in the United States. Evidence shows that behavioral health conditions are common among these individuals, but understanding of their behavioral health needs is limited. This study aimed to understand the behavioral health characteristics and needs of patients with high hospital utilization patterns in Camden, New Jersey.

Methods

The sample consisted of patients in a care management intervention for individuals with patterns of high hospital utilization who were referred for behavioral health assessments (N = 195). A clinical psychologist conducted the assessments, which informed a multiaxial evaluation with diagnostic criteria from the Diagnostic and Statistical Manual of Mental Disorders and a Mental Status Examination, to facilitate accurate diagnosis. Demographic characteristics, housing instability, exposure to trauma, and health care service utilization data were also collected through self-report and chart reviews.

Results

Ninety percent of patients were diagnosed with a psychiatric and/or active substance use disorder. Depression was the most common psychiatric disorder and alcohol use was the most common substance use disorder. However, only 10% of patients with an active substance use disorder were in treatment, and only 17% of patients with a mental health diagnosis were receiving mental health treatment. Nearly all (91%) patients reported having a primary care provider at the time of assessment and most had seen their primary care provider within three months of their last hospital discharge. Non-medical barriers to health and wellness, specifically housing instability and exposure to trauma, were also common (35 and 61% of patients, respectively) among patients.

Conclusion

Findings highlight the importance of identifying and treating patients with behavioral health needs in the primary care setting. Developing connections with community agencies who provide behavioral health and substance use treatment can enhance primary care providers’ efforts to address their patients’ non-medical barriers to treatment, as can embedding behavioral health providers within primary care offices. The study also underscores the need for trauma-informed care in primary care settings.

Medications for Treatment of Opioid Use Disorder among Persons Living with HIV

PURPOSE OF REVIEW

Recent HIV outbreaks have occurred as a result of the current US opioid epidemic. Providing medications for opioid use disorder (MOUD) with methadone, buprenorphine, and extended-release naltrexone is essential to achieving optimal HIV treatment outcomes including viral suppression and retention in treatment. This review describes the pharmacology of MOUD with specific attention to interactions with antiretroviral therapy, and to the effect of MOUD on HIV treatment outcomes.

RECENT FINDINGS

Methadone and buprenorphine both improve HIV viral suppression, adherence to antiretroviral therapy, and overall mortality for persons with opioid use disorder (OUD). Extended-release naltrexone has been most extensively studied in persons with HIV leaving incarcerated settings, and improves HIV viral suppression in that context. Strategies that integrate MOUD and HIV treatment are crucial to optimize viral suppression. The differing pharmacokinetic and delivery characteristics of these MOUD offer diverse options. Given the chronic and relapsing nature of both HIV and OUD, long-term approaches are required.

"No more falling through the cracks": A qualitative study to inform measurement of integration of care of HIV and opioid use disorder

INTRODUCTION

Integration of HIV- and opioid use disorder (OUD)-related care is associated with improved patient outcomes. Our goal was to develop a novel instrument for measuring quality of integration of HIV and OUD-related care that would be applicable across diverse care settings.

METHODS

Grounded in community-based participatory research principles, we conducted a qualitative study from August through November 2017 to inform modification of the Behavioral Health Integration in Medical Care (BHIMC) instrument, a validated measure of quality of integration of behavioral health in primary care. We conducted semi-structured interviews of patients (n = 22), focus groups with clinical staff (n = 24), and semi-structured interviews of clinic leadership (n = 5) in two urban centers in Connecticut.

RESULTS

We identified three themes that characterize optimal integration of HIV- and OUD-related care: (1) importance of mitigating mismatches in resources and knowledge, particularly resources to address social risks and knowledge gaps about evidence-based treatments for OUD; (2) need for patient-centered policies and inter-organization communication, and (3) importance of meeting people where they are, geographically and at their stage of change. These themes highlighted aspects of integrated care for HIV and OUD not captured in the original BHIMC.

CONCLUSIONS

Patients, clinical staff, and organization leadership perceive that addressing social risks, communication across agencies, and meeting patients in their psychosocial and structural context are important for optimizing integration of HIV and OUD-related care. Our proposed, novel instrument is a step towards measuring and improving service delivery locally and nationally for this vulnerable population.

Interpretation and integration of the federal substance use privacy protection rule in integrated health systems: A qualitative analysis

BACKGROUND

Federal regulations (42 CFR Part 2) provide special privacy protections for persons seeking treatment for substance use disorders. Primary care providers, hospitals, and health care organizations have struggled to balance best practices for medical care with adherence to 42 CFR Part 2, but little formal research has examined this issue. The aim of this study was to explore institutional variability in the interpretation and implementation of 42 CFR Part 2 regulations related to health systems data privacy practices, policies, and information technology architecture.

METHODS

This was a cross-sectional qualitative study using purposive sampling to conduct interviews with privacy/legal officers (n = 17) and information technology specialists (n = 10) from 15 integrated healthcare organizations affiliated with three research nodes of the National Institute on Drug Abuse (NIDA) National Drug Abuse Treatment Clinical Trials Network (CTN). Trained staff completed a short survey and digitally recorded semi-structured qualitative interview with each participant. Interviews were transcribed and coded within Atlas.ti. Framework analysis was used to identify and organize key themes across selected codes.

RESULTS

Participants voiced concern over balancing patient safety with 42 CFR Part 2 privacy protections. Although similar standards of protection regarding release of information outside of the health system was described, numerous workarounds were used to manage intra-institutional communication and care coordination. To align 42 CFR Part 2 restrictions with electronic health records, health systems used sensitive note designation, "break the glass" technology, limited role-based access for providers, and ad hoc solutions (e.g., provider messaging).

CONCLUSIONS

In contemporary integrated care systems, substance-related EHR records (e.g., patient visit history, medication logs) are often accessible internally without specific consent for sharing despite the intent of 42 CFR Part 2. Recent amendments to 42 CFR Part 2 have not addressed information sharing needs within integrated care settings.

A new brief opioid stigma scale to assess perceived public attitudes and internalized stigma: Evidence for construct validity

One key strategy to improve treatment access for persons with opioid use disorder (OUD) is overcoming stigma that is internalized by such individuals. Because few theoretically-derived, multidimensional measures of substance abuse stigma exist, we contribute a brief, theoretically-based measure of opioid-related stigma (adapted from Corrigan's Self-Stigma of Mental Illness Scale) to assess perceived stigma and internalized stigma among individuals with OUD. This study presents initial validation of the newly-developed Brief Opioid Stigma Scale among 387 adults who entered an inpatient opioid managed-withdrawal program. The scale assesses: (1) Stereotype awareness ("Aware"), or the extent to which individuals who use opioids perceive community members to believe OUD-related stereotypes; (2) Stereotype agreement ("Agree"), or the endorsement of stigmatizing beliefs by individuals who use opioids; (3) Self-esteem decrement ("Harm"), or the diminution of self-esteem due to these negative stereotypes' impacts on self-worth. Psychosocial measures including self-esteem, depressive symptoms, mental and physical functioning, and desire for aftercare OUD medication treatment, were administered to assess construct validity. Results showed that greater endorsement of the "harm" stigma subscale was associated with greater depressive symptoms, lower self-esteem, and poorer mental and physical functioning. The "aware" stigma subscale displayed similar overall patterns of associations with self-esteem and depression but to a lesser magnitude. The "aware" stigma subscale was positively associated with desire for aftercare methadone and naltrexone treatment, and the "harm" subscale was positively associated with desire for aftercare buprenorphine treatment. Results indicated good initial construct validity. Tailored stigma interventions are recommended for specific aftercare OUD medication treatments.

Integration of Buprenorphine Treatment with Primary Care: Comparative Effectiveness on Retention, Utilization, and Cost

Opioid use disorder (OUD) is a national crisis. Health care must achieve greater success than it has to date in helping opioid users achieve recovery. Integration of comprehensive primary care with treatment for OUD has the potential to increase care access among the substance-using population, improve outcomes, and reduce costs. However, little is known about the effectiveness of such care models. The Comprehensive Care Practice (CCP), a primary care practice located in Maryland, implemented a care model that blends buprenorphine treatment for OUD with attention to primary care needs. This study evaluates the model by comparing patients with OUD treated in CCP and other Maryland facilities in a large state Medicaid program. Compared to the non-CCP patient group (n = 867), the CCP group (n = 131) had a higher 6-month buprenorphine treatment retention rate (79% vs. 61%, adjusted average marginal effect (AME) = 0.17, P < 0.001). CCP patients also had fewer hospital stays in the 12-month follow-up period (0.22 vs. 0.41, AME = -0.17, P = 0.005), and lower total cost (US$10,942 vs. $13,097, AME = -$4554, P < 0.001) and hospital stay cost (US$1448 vs. $4265, AME = -$2609, P = 0.001), but higher buprenorphine pharmacy cost (US$3867 vs. $2781, AME = $987, P < 0.001). Other measures, including emergency department utilization and cost, substance abuse cost, and non-buprenorphine pharmacy cost, were not statistically different between the 2 groups. Results suggested that patients, as well as the health care system, can benefit from an integrated model of buprenorphine treatment and primary care for OUD with better treatment retention, fewer hospital stays, and lower costs.

Commentary on Socias et al. (2018): Clinical research perspectives on cannabis use in opioid agonist treatment

Research is needed to determine clinical criteria as to who should be using cannabis therapeutically, how to implement therapeutic use of cannabis in opioid agonist treatment (OAT) settings optimally, and other behavioral approaches to improving OAT retention and outcomes.

Cost of pharmacotherapy for opioid use disorders following inpatient detoxification

OBJECTIVES

To estimate the costs of providing extended-release injectable naltrexone (XR-NTX) and buprenorphine-naloxone (BUP-NX) following inpatient detoxification using data derived from a multisite randomized controlled trial at 8 US community-based treatment programs.

STUDY DESIGN

Cost data were collected for 3 intervention phases: program start-up, inpatient detoxification, and up to 24 weeks of medication induction and management visits (post detoxification). Cost analyses were from the healthcare sector perspective (2015 US$); patient costs are also reported.

METHODS

We conducted site visits, administered a cost survey to treatment programs, and analyzed study data on medication and services utilization. Nationally representative sources were used to estimate unit costs. Uncertainty was evaluated in sensitivity analyses.

RESULTS

Mean start-up costs were $1071 per program for XR-NTX and $828 per program for BUP-NX. Mean costs per participant were $5416 for XR-NTX (57% detoxification, 37% medication, 3% provider, 3% patient) and $4148 for BUP-NX (64% detoxification, 12% medication, 10% provider, 14% patient). Total cost per participant ranged by site from $2979 to $8963 for XR-NTX and from $2521 to $6486 for BUP-NX.

CONCLUSIONS

For treatment providers, offering XR-NTX and/or BUP-NX as part of existing detoxification treatment modalities generates modest costs in addition to the costs of detoxification, which vary substantially among the 8 sites. From the patient's perspective, the costs associated with medication management visits may be a barrier for some individuals considering these treatments.

Chronic preoperative opioid use is a risk factor for increased complications, resource use, and costs after cervical fusion

BACKGROUND CONTEXT

As health-care transitions to value-based models, there has been an increased focus on patient factors that can influence peri- and postoperative adverse events, resource use, and costs. Many studies have reported risk factors for systemic complications after cervical fusion, but none have studied chronic opioid therapy (COT) as a risk factor.

PURPOSE

The objective of this study was to answer the following questions from a large cohort of patients who underwent primary cervical fusion for degenerative pathology: (1) What is the patient profile associated with preoperative COT? (2) Is preoperative COT a risk factor for 90-day systemic complications, emergency department (ED) visits, readmission, and 1-year adverse events? (3) What are the risk factors and 1-year adverse events related to long-term postoperative opioid use? (4) How much did payers reimburse for management of complications and adverse events?

STUDY DESIGN

This is a retrospective review of Humana commercial insurance data (2007-Q3 2015).

PATIENT SAMPLE

The patient sample included 29,101 patients undergoing primary cervical fusion for degenerative pathology.

METHODS

Patients and procedures of interest were included using International Classification of Diseases (ICD) coding. Patients with opioid prescriptions for >6 months before surgery were considered as having preoperative COT. Patients with continued opioid use until 1-year after surgery were considered as long-term users. Descriptive analysis of patient cohorts has been done. Multiple-variable logistic regression analyses adjusting for approach, number of levels of surgery, discharge disposition, and comorbidities were done to answer first three study questions. Reimbursement data from insurers have been reported to answer our fourth study question.

RESULTS

Of the entire cohort, 6,643 (22.8%) had preoperative COT. Preoperative COT was associated with a higher risk of 90-day wound complications (odds ratio [OR] 1.39, 95% confidence interval [CI]: 1.16-1.66), all-cause 90-day ED visits (adjusted OR 1.22, 95% CI: 1.13-1.32), and pain-related ED visits (adjusted OR 1.39, 95% CI: 1.24-1.55). Patients who had preoperative COT were more likely to receive epidural or facet joint injections within 1 year after surgery (adjusted OR 1.68, 95% CI: 1.47-1.92). These patients were also more likely to undergo a repeat cervical fusion within a year than patients who did not have preoperative COT (adjusted OR 1.21, 95% CI: 1.01-1.43). Preoperative COT had a higher likelihood of long-term use after surgery (adjusted OR 4.72, 95% CI: 4.41-5.06). Long-term opioid use after surgery was associated with a higher risk of new-onsetconstipation (adjusted OR 1.34, 95% CI: 1.22-1.48). The risk of complications and adverse events was not found to be significant in patients with <3 months of preoperative opioid use or those who stopped opioids for at least 6 weeks before surgery. The cost of additional resource use for medications, ED visits, constipation, injections, and revision fusion ranged from $623 to $27,360 per patient.

CONCLUSIONS

Preoperative opioid use among patients who underwent cervical fusion increases complication rates, postoperative opioid usage, health-care resource use, and costs. These risks may be reduced by restricting the duration of preoperative opioid use or weaning off before surgery. Better understanding and management of pain in the preoperative period with judicious use of opioids is critical to enhance outcomes after cervical fusion surgery.

Future directions for medication assisted treatment for opioid use disorder with American Indian/Alaska Natives

The U.S. is experiencing an alarming opioid epidemic, and although American Indians and Alaska Natives (AI/ANs) are especially hard hit, there is a paucity of opioid-related treatment research with these communities. AI/ANs are second only to Whites in the U.S. for overdose mortality. Thus, the National Institute on Drug Abuse convened a meeting of key stakeholders to elicit feedback on the acceptability and uptake of medication assisted treatment (MAT) for opioid use disorders (OUDs) among AI/ANs. Five themes from this one-day meeting emerged: 1) the mismatch between Western secular and reductionistic medicine and the AI/AN holistic healing tradition; 2) the need to integrate MAT into AI/AN traditional healing; 3) the conflict between standardized MAT delivery and the traditional AI/AN desire for healing to include being medicine free; 4) systemic barriers; and 5) the need to improve research with AI/ANs using culturally relevant methods. Discussion is organized around key implementation strategies informed by these themes and necessary for the successful adoption of MAT in AI/AN communities: 1) type of medication; 2) educational interventions; 3) coordination of care; and 4) adjunctive psychosocial counseling. Using a community-based participatory research approach is consistent with a "two eyed seeing" approach that integrates Western and Indigenous worldviews. Such an approach is needed to develop impactful research in collaboration with AI/AN communities to address OUD health disparities.

Maternal Opioid Use Disorder and Neonatal Abstinence Syndrome Among Rural US Residents, 2007-2014

PURPOSE

Opioid use disorder (OUD) during pregnancy is associated with poor maternal and infant outcomes, including neonatal abstinence syndrome (NAS), and both maternal OUD and NAS are increasing disproportionately among rural residents. This study describes the trajectory and characteristics associated with diagnosis of maternal OUD or NAS among rural residents who gave birth at different types of hospitals based on rural/urban location and teaching status.

METHODS

Hospital discharge data from the all-payer National Inpatient Sample were used to describe maternal OUD and infant NAS among rural residents from 2007-2014. Hospitals were categorized as rural, urban teaching, and urban nonteaching. We estimated incidence trends by hospital categories, followed by multivariable logistic regression analyses to identify correlates of OUD and NAS among rural residents, stratified by hospital category.

FINDINGS

Incidence of maternal OUD increased in all hospital categories, with higher rates (8.9/1,000 deliveries) among rural residents who gave birth at urban teaching hospitals compared with those who gave birth at rural hospitals (4.3/1,000 deliveries) or urban nonteaching hospitals (3.6/1,000 deliveries; P < .001). A similar pattern was observed for infant NAS. In multivariable models, the association between maternal OUD and infant NAS diagnoses and hospital category differed by rurality (micropolitan vs. noncore.) CONCLUSIONS: There has been a sustained increase in both maternal OUD and NAS diagnoses among rural residents. Measured sociodemographic and clinical correlates of maternal OUD and NAS differ by hospital category, indicating variability across hospital locations in patient populations and clinical needs for rural residents with these conditions.

Causes of Death After Nonfatal Opioid Overdose

Importance

A recent increase in patients presenting with nonfatal opioid overdoses has focused clinical attention on characterizing their risks of premature mortality.

Objective

To describe all-cause mortality rates, selected cause-specific mortality rates, and standardized mortality rate ratios (SMRs) of adults during their first year after nonfatal opioid overdose.

Design, Setting, and Participants

This US national longitudinal study assesses a cohort of patients aged 18 to 64 years who were Medicaid beneficiaries and experienced nonfatal opioid overdoses. The Medicaid data set included the years 2001 through 2007. Death record information was obtained from the National Death Index. Data analysis occurred from October 2017 to January 2018.

Main Outcomes and Measures

Crude mortality rates per 100 000 person-years were determined in the first year after nonfatal opioid overdose. Standardized mortality rate ratios (SMR) were estimated for all-cause and selected cause-specific mortality standardized to the general population with respect to age, sex, and race/ethnicity.

Results

The primary cohort included 76 325 adults and 66 736 person-years of follow-up. During the first year after nonfatal opioid overdose, there were 5194 deaths, the crude death rate was 778.3 per 10 000 person-years, and the all-cause SMR was 24.2 (95% CI, 23.6-24.9). The most common immediate causes of death were substance use-associated diseases (26.2%), diseases of the circulatory system (13.2%), and cancer (10.3%). For every cause examined, SMRs were significantly elevated, especially with respect to drug use-associated diseases (SMR, 132.1; 95% CI, 125.6-140.0), HIV (SMR, 45.9; 95% CI, 39.5-53.0), chronic respiratory diseases (SMR, 41.1; 95% CI, 36.0-46.8), viral hepatitis (SMR, 30.6; 95% CI, 22.9-40.2), and suicide (SMR, 25.9; 95% CI, 22.6-29.6), particularly including suicide among females (SMR, 47.9; 95% CI, 39.8-52.3).

Conclusions and Relevance

In a US national cohort of adults who had experienced a nonfatal opioid overdose, a marked excess of deaths was attributable to a wide range of substance use-associated, mental health, and medical conditions, underscoring the importance of closely coordinating the substance use, mental health, and medical care of this patient population.

Implementing Treatment of Opioid-Use Disorder in Rural Settings: a Focus on HIV and Hepatitis C Prevention and Treatment

PURPOSE OF REVIEW

To describe the epidemiology of opioid-use disorder in the rural United States (U.S.) as it pertains to HIV and hepatitis C transmission and treatment resources.

RECENT FINDINGS

Heroin and fentanyl analogs have surpassed prescription opioids in their availability in rural opioid markets adding to HIV and hepatitis C (HCV) and overdose risks. Only 18% of rural individuals live in towns with inpatient services which are of limited quality and utility. Opioid treatment programs that provide methadone are not located in rural areas and only 3% of the primary care providers have the ability to prescribe buprenorphine. National models and resources have been established but lack implementation in rural areas leading to ongoing HIV and HCV transmission and overdose. Addressing the adverse impact of opioids in the rural U.S. will require a concerted effort to implement effective treatments according to national standards.

Comparison between buprenorphine provider availability and opioid deaths among US counties

BACKGROUND

Buprenorphine is an effective medication for the treatment of opioid addiction, but current barriers to buprenorphine access limit treatment availability for many patients. We identify and characterize regions within the United States (US) with poor buprenorphine access relative to the observed burden of overdose deaths.

METHODS

This cross sectional study includes US county-level data on the number of available buprenorphine providers (Substance Abuse and Mental Health Services Administration Buprenorphine Treatment Practitioner Locator) and the number of opioid-related overdose deaths between 2013 and 2015 (Centers for Disease Control and Prevention WONDER Database). Counties with fewer than 10 deaths during this time period were excluded to maintain patient privacy. Population-adjusted county death rates and provider availability were compared to identify locations with high disease burdens and limited buprenorphine access. The presence of significant clustering across the dataset was evaluated using Global Moran's I and zones of significant spatial clusters and anomalies were identified using Local Indicator of Spatial Autocorrelation.

RESULTS

County data were available for 846 counties from 49 states and the District of Columbia, comprising 83% of the US population. The median number of opioid overdose deaths per county was 20.0 deaths per 100,000 residents (interquartile range 13.4-29.9, range 2.9 to 108.8). The number of buprenorphine providers per 100,000 county residents ranged from 0 to 45, with a median of 5.9 (interquartile range 3.2 to 9.5). Global Moran's I analysis yielded significant clustering in the distribution of both providers and deaths, with notable significant clusters of higher than average providers and deaths in the Northeast, and scattered mismatched regions of lower-than-average providers and higher-than-average deaths across the Southern, Midwestern, and Western US. Graphical analysis of buprenorphine provider availability and overdose burden reveals limited treatment access relative to overdose deaths throughout much of the Midwestern and Southern US.

CONCLUSIONS

Substantial county-level imbalances between the availability of buprenorphine providers and the burden of opioid overdose deaths are present within the US.

Addressing Unhealthy Substance Use in Primary Care

Unhealthy substance use is common in primary care populations and is a major contributor to morbidity and mortality. Two key strategies to address unhealthy substance use in primary care are the process of screening, brief intervention, and referral to treatment (SBIRT), and integration of treatment for substance use disorders into primary care. Implementation of SBIRT requires buy-in from practice leaders, careful planning, and staff and primary care provider training. Primary care-based treatment of opioid and alcohol use disorders can be effective; more data are needed to better understand the benefits of these models and identify means of treating other substance use disorders in primary care.

National Institute on Drug Abuse International Program: improving opioid use disorder treatment through international research training

PURPOSE OF REVIEW

For more than 25 years, the National Institute on Drug Abuse (NIDA) has supported research-training programs, establishing a global research network and expanding the knowledge base on substance use disorders. International research to inform approaches to opioid addiction is particularly important and relevant to the United States, where opioid misuse, addiction, and overdose constitute an emerging public health crisis. This article summarizes the NIDA International Program and illustrates its impact by reviewing recent articles about treatment approaches for opioid use disorders (OUD).

RECENT FINDINGS

Studies in several countries have demonstrated the effectiveness of physician office-based opioid substitution therapies. Other research has demonstrated the effectiveness of different formulations and doses of the opioid antagonist naltrexone, as well as different approaches to providing naloxone to treat opioid overdose. Continuing research into implementation of evidence-based treatment in international settings with limited resources is applicable to US regions that face similar structural, legal, and fiscal constraints.

SUMMARY

The current review describes international research on OUD treatment and opioid overdose, most coauthored by former NIDA fellows. The findings from outside the United States have important implications for best practices domestically and in other countries that are experiencing increases in OUD prevalence and related overdose deaths.
