Opioid Use Disorder Treatment Decision Making And Care Navigation Upon Release From Prison: A Feasibility Study

Informing evidence-based medicine for opioid use disorder using pharmacoeconomic studies

INTRODUCTION

The health and economic consequences of inadequately treated opioid use disorder (OUD) are substantial. Healthcare systems in the United States (US) and other countries are facing a growing healthcare crisis due to opioids. Although effective medications for OUD exist, relying solely on clinical information is insufficient for addressing the opioid crisis.

AREAS COVERED

In this review, the role of pharmacoeconomic studies in informing evidence-based medication treatment for OUD is discussed, with a particular emphasis on the US healthcare system, where the economic burden is significantly higher than the global average. The scope/objective of pharmacoeconomics as a distinct scientific research program is briefly defined, followed by a discussion of existing evidence informed by data from systematic reviews, in addition to a convenience sample of recently published pharmacoeconomic studies and protocols. The review also explores the need for methodological advancements in the field.

EXPERT OPINION

Despite the potential of pharmacoeconomic research in shaping evidence-based medicine for OUD, significant challenges limiting its real-world application remain. How to address these challenges are explored, including how to combine cost-effectiveness and budget impact analyses to address the needs of the healthcare system as a whole and specific stakeholders interested in adopting new OUD treatment strategies.

Access to medications for opioid use disorder for formerly incarcerated individuals during community reentry: a mini narrative review

Medications for opioid use disorder (MOUD) are especially important for formerly incarcerated individuals with opioid use disorder (OUD) and can reduce the risk of re-arrest and overdose during community reentry. Unfortunately, few formerly incarcerated individuals are able to access MOUD within the community, missing a critical tool for rehabilitation. A mini narrative review was conducted to highlight the published work that has been done to improve access to MOUD for formerly incarcerated individuals during reentry. The results yielded 15 records describing intervention evaluations, program descriptions, and research in progress. Most work is ongoing, showing promise that researchers have identified the importance of this problem. However additional research should be done to include other stakeholders and address the limitations of existing interventions and programs. Continued efforts can help ensure that formerly incarcerated individuals can safely and successfully reintegrate into society.

Barriers and facilitators to opioid agonist treatment (OAT) engagement among individuals released from federal incarceration into the community in Ontario, Canada

INTRODUCTION

Correctional populations with opioid use disorder experience increased health risks during community transition periods. Opioid Agonist Treatment (OAT) can reduce these risks, but retention is a key challenge. This study addresses a knowledge gap by describing facilitators and barriers to OAT engagement among federal correctional populations released into the community in Ontario, Canada.

METHODS

This article describes results from a longitudinal mixed-methods study examining OAT transition experiences among thirty-five individuals released from federal incarceration in Ontario, Canada. Assessments were completed within one year of participants' release. Data were thematically analyzed.

RESULTS

The majority (77%) of participants remained engaged in OAT, however, 69% had their release suspended and 49% returned to custody. Key facilitators for OAT engagement included flexibility, positive staff rapport, and structure. Fragmented OAT transitions, financial OAT coverage, balancing reintegration requirements, logistical challenges, and inaccessibility of 'take-home' OAT medications were common barriers.

CONCLUSIONS

Post-incarceration transition periods are critical for OAT retention, yet individuals in Ontario experience barriers to OAT engagement that contribute to treatment disruptions and related risks such as relapse and/or re-incarceration. Additional measures to support community OAT transitions are required, including improved discharge planning, amendments to OAT and financial coverage policies, and an expansion of OAT options.

The Community-Based Medication-First program for opioid use disorder: a hybrid implementation study protocol of a rapid access to buprenorphine program in Washington State

BACKGROUND

Opioid use disorder (OUD) is a serious health condition that is effectively treated with buprenorphine. However, only a minority of people with OUD are able to access buprenorphine. Many access points for buprenorphine have high barriers for initiation and retention. Health care and drug treatment systems have not been able to provide services to all-let alone the majority-who need it, and many with OUD report extreme challenges starting and staying on buprenorphine in those care settings. We describe the design and protocol for a study of a rapid access buprenorphine program model in six Washington State communities at existing sites serving people who are unhoused and/or using syringe services programs. This study aimed to test the effectiveness of a Community-Based Medication-First Program model.

METHODS

We are conducting a hybrid effectiveness-implementation study of a rapid access buprenorphine model of care staffed by prescribers, nurse care managers, and care navigators. The Community-Based Medication-First model of care was designed as a 6-month, induction-stabilization-transition model to be delivered between 2019 and 2022. Effectiveness outcomes will be tested by comparing the intervention group with a comparison group derived from state records of people who had OUD. Construction of the comparison group will align characteristics such as geography, demographics, historical rates of arrests, OUD medication, and health care utilization, using restriction and propensity score techniques. Outcomes will include arrests, emergency and inpatient health care utilization, and mortality rates. Descriptive statistics for buprenorphine utilization patterns during the intervention period will be documented with the prescription drug monitoring program.

DISCUSSION

Results of this study will help determine the effectiveness of the intervention. Given the serious population-level and individual-level impacts of OUD, it is essential that services be readily available to all people with OUD, including those who cannot readily access care due to their circumstances, capacity, preferences, and related systems barriers.

Impact of a jail-based treatment decision-making intervention on post-release initiation of medications for opioid use disorder

INTRODUCTION

Opioid use disorder (OUD) is common among people in jail and is effectively treated with medications for OUD (MOUD). People with OUD may have an incomplete or inaccurate understanding of OUD and MOUD, and of how to access care. We evaluated an OUD treatment decision making (TDM) intervention to determine whether the intervention increased MOUD initiation post-release.

METHODS

We conducted an observational retrospective cohort study of the TDM intervention on initiation of MOUD, individuals with records data indicating confirmed or suspected OUD incarcerated in four eligible jails were eligible to receive the intervention. Time-to-event analyses of the TDM intervention were conducted using Cox proportional hazard modeling with MOUD as the outcome.

RESULTS

Cox proportional hazard modeling, with the intervention modeled as having a time-varying effect due to violation of the proportionality assumption, indicated that those receiving the TDM intervention (n = 568) were significantly more likely to initiate MOUD during the first month after release from jail (adjusted hazard ratio 6.27, 95 % C.I. 4.20-9.37), but not in subsequent months (AHR 1.33 95 % C.I. 0.94-1.89), adjusting for demographics, prior MOUD, or felony or gross misdemeanor arrest in the prior year compared to those not receiving the intervention (n = 3174).

CONCLUSION

The TDM intervention was associated with a significantly higher relative hazard of starting MOUD, specifically during the first month after incarceration. However, a minority of all eligible people received any MOUD. Future research should examine ways to increase initiation on MOUD immediately after (or ideally during) incarceration.

Routes of non-traditional entry into buprenorphine treatment programs

BACKGROUND

Excessive prescribing, increased potency of opioids, and increased availability of illicit heroin and synthetic analogs such as fentanyl has resulted in an increase of overdose fatalities. Medications for opioid use disorder (MOUD) significantly reduces the risk of overdose when compared with no treatment. Although the use of buprenorphine as an agonist treatment for opioid use disorder (OUD) is growing significantly, barriers remain which can prevent or delay treatment. In this study we examine non-traditional routes which could facilitate entry into buprenorphine treatment programs.

METHODS

Relevant, original research publications addressing entry into buprenorphine treatment published during the years 1989-2019 were identified through PubMed, PsychInfo, PsychArticles, and Medline databases. We operationalized key terms based on three non-traditional paths: persons that entered treatment via the criminal justice system, following emergencies, and through community outreach.

RESULTS

Of 462 screened articles, twenty studies met the inclusion criteria for full review. Most studies were from the last several years, and most (65%) were from the Northeastern region of the United States. Twelve (60%) were studies suggesting that the criminal justice system could be a potentially viable entry route, both pre-release or post-incarceration. The emergency department was also found to be a cost-effective and viable route for screening and identifying individuals with OUD and linking them to buprenorphine treatment. Fewer studies have documented community outreach initiatives involving buprenorphine. Most studies were small sample size (mean = < 200) and 40% were randomized trials.

CONCLUSIONS

Despite research suggesting that increasing the number of Drug Addiction Treatment Act (DATA) waived physicians who prescribe buprenorphine would help with the opioid treatment gap, little research has been conducted on routes to increase utilization of treatment. In this study, we found evidence that engaging individuals through criminal justice, emergency departments, and community outreach can serve as non-traditional treatment entry points for certain populations. Alternative routes could engage a greater number of people to initiate MOUD treatment.

Opioid Overdoses for Recently Incarcerated Individuals: Toxicology Results and Risk Evaluations

Background: The opioid epidemic continues to challenge the United States, fueled by illicitly manufactured fentanyl. All stakeholders involved in fighting the opioid epidemic, from medical providers to policy makers, will benefit from understanding what contributes to overdoses. Recently incarcerated individuals represent a particularly vulnerable population. Methods: We performed a retrospective review of Jefferson County Coroner data for overdose deaths by postmortem toxicology between January 2017 and December 2018. Patients were cross-referenced with Jefferson County Department of Corrections (DOC) records, with inclusion of individuals with violations after January 2016 to focus on recently incarcerated individuals. We analyzed substances found in toxicology reports and substance risk level assigned based on screening by the DOC. Results: A total of 575 opioid overdose deaths occurred in Jefferson County from 2017-2018, with 55 of these individuals having interaction with the DOC after January 1, 2016. DOC population individuals had statistically significant higher findings of amphetamines/methamphetamines. Individuals from the DOC population had higher frequencies of fentanyl, heroin, cocaine, and cannabinoid/THC; however, these differences were not statistically significant. Prisoners with substance risk assessment scores of high or very high had fewer days from release to overdose death. Conclusion: Fentanyl remains a major contributor to overdose death, including those recently incarcerated. Substance risk assessment tools should drive referral for treatment while in prison and at time of release. These results provide better insight into the opioid epidemic and may help guide medical care, specifically for recently incarcerated individuals.
