Associations between pharmacotherapy for opioid dependence and clinical and criminal justice outcomes among adults with co-occurring serious mental illness

Community-based substance use treatment programs for reentering justice-involved adults: A scoping review

Introduction

For adults involved with the criminal justice system who are reentering their communities post-incarceration, there is a large need for community-based substance use treatment. Little is known, however, about the types, availability, and benefits of programs targeting the reentry population in community settings that operate independently from the criminal justice system.

Methods

We conducted a scoping review of community-based treatment programs for substance use among reentering justice-involved adults to examine the contemporary state of literature and identify research gaps. We searched four databases for peer-reviewed articles conducted in the United States and published between 2017 and 2021.

Results

The final sample included 58 articles. Interventions varied, but the two most prominent were medications for opioid use disorder (35%) and peer support or social support interventions (22.4%). Studies were more likely to show positive impact on substance use outcomes than criminal justice outcomes. Themes were identified around participant characteristics, treatment delivery, and treatment benefits.

Conclusions

Findings from this scoping review suggest that the range of evidence-based strategies for substance use treatment targeting the reentry population is growing, but there is a need for additional research that examines implementation, cost effectiveness, and racial/ethnic disparities.

Impact of Medication-Based Treatment on Health Care Utilization Among Individuals With Opioid Use Disorder

OBJECTIVE

This study evaluated the association between medication for opioid use disorder (MOUD) and health care utilization over time among a sample of treatment-seeking individuals with opioid use disorder. In contrast to previous studies, this study used a novel measure of MOUD adherence, more comprehensive utilization data, and analyses that controlled for detailed individual and social determinants of health.

METHODS

This study was a secondary analysis of a comparative effectiveness trial (N=570) of extended-release naltrexone versus buprenorphine-naloxone. The outcome of interest was usage of nonstudy acute care, inpatient and outpatient addiction services, and other outpatient services across 36 weeks of assessment. Adherence (percentage of days taking MOUD) was defined as low (<20%), medium (≥20% but <80%), or high (≥80%). A two-part model evaluated the probability of utilizing a resource and the quantity (utilization days) of the resource consumed. A time-varying approach was used to examine the effect of adherence in a given month on utilization in the same month, with analyses controlling for a wide range of person-level characteristics.

RESULTS

Participants with high adherence (vs. low) were significantly less likely to use inpatient addiction (p<0.001) and acute care (p<0.001) services and significantly more likely to engage in outpatient addiction (p=0.045) and other outpatient (p=0.042) services.

CONCLUSIONS

These findings reinforce the understanding that greater MOUD adherence is associated with reduced usage of high-cost health services and increased usage of outpatient care. The results further suggest the need for enhanced access to MOUD and for interventions that improve adherence.

Non-overdose acute care hospitalizations for opioid use disorder among commercially-insured adults: a retrospective cohort study

BACKGROUND

Acute care inpatient admissions outside of psychiatric facilities have been increasingly identified as a critical touchpoint for opioid use disorder (OUD) treatment. We sought to describe non-opioid overdose hospitalizations with documented OUD and examine receipt of post-discharge outpatient buprenorphine.

METHODS

We examined acute care hospitalizations with an OUD diagnosis in any position within US commercially-insured adults age 18-64 years (IBM MarketScan claims, 2013-2017), excluding opioid overdose diagnoses. We included individuals with ≥ 6 months of continuous enrollment prior to the index hospitalization and ≥ 10 days following discharge. We described demographic and hospitalization characteristics, including outpatient buprenorphine receipt within 10 days of discharge.

RESULTS

Most (87%) hospitalizations with documented OUD did not include opioid overdose. Of 56,717 hospitalizations (49,959 individuals), 56.8% had a primary diagnosis other than OUD, 37.0% had documentation of an alcohol-related diagnosis code, and 5.8% end in a self-directed discharge. Where opioid use disorder was not the primary diagnosis, 36.5% were due to other substance use disorders, and 23.1% were due to psychiatric disorders. Of all non-overdose hospitalizations who had prescription medication insurance coverage and who were discharged to an outpatient setting (n = 49, 237), 8.8% filled an outpatient buprenorphine prescription within 10 days of discharge.

CONCLUSIONS

Non-overdose OUD hospitalizations often occur with substance use disorders and psychiatric disorders, and very few are followed by timely outpatient buprenorphine. Addressing the OUD treatment gap during hospitalization may include implementing medication for OUD for inpatients with a broad range of diagnoses.

Co-occurring opioid use disorder and serious mental illness: A selective literature review

OBJECTIVE

The overarching goal of this review is to provide a clinical overview of epidemiology, diagnosis, and treatment, and to discuss the public health impact, social determinants including access to care, and implications for health care delivery and research. It is estimated that approximately 1 in 4 individuals suffering from a serious mental illness (SMI) may have a co-occurring opioid use disorder (OUD). In these individuals, the overall disease burden is higher and clinical outcomes are worse compared to those without a co-occurring illness, making an integrated approach to diagnosis and treatment an urgent priority.

METHODS

We conducted a selective review of the literature to investigate prevalence, etiology for co-occurring OUD and SMI, and diagnostic and clinical guidelines in the United States, and consideration special populations.

FINDINGS

Our findings suggest that, despite the high prevalence of co-occurring OUD and SMI, contemporary diagnostics and treatment approaches are underutilized in this patient population. The literature also suggests that both pharmacological and psychosocial treatment approaches need to be tailored to optimize clinical management, and that integrated treatment is pivotal for improving overall outcomes, yet comprehensive clinical guidelines for co-occurring OUD and SMI are lacking at this time.

Pilot testing a tool to determine the costs and time associated with community pharmacy-based administration of injectable naltrexone

BACKGROUND

Medications for opioid use disorder (MOUD), including injectable naltrexone (IN), are part of evidence-based OUD treatments. MOUD access often is limited, especially in rural communities. When authorized to administer non-vaccination injections, pharmacists can increase IN accessibility. However, inadequate reimbursement for pharmacist-administered IN can hinder widespread adoption.

OBJECTIVES

To pilot test a process to obtain a preliminary estimate of the total costs and time associated with community-pharmacist administered IN.

METHODS

A purposively-selected sample of key informants at community pharmacies administering IN were surveyed about time and cost for best practice IN activities. Respondents estimated the time to perform activities and average pharmacist/pharmacy technician hourly salary, which were used to calculate administration costs.

RESULTS

The approach to estimate time and costs was feasible. Administrative costs (mean = $93, range: $48-$164) and time (mean = 123 min., range: 63-220 min.) to administer IN varied widely. Pharmacists'/pharmacy technicians' roles varied by pharmacy.

CONCLUSIONS

Pharmacists allocate significant time and resources to administer IN. Insufficient reimbursement may disincentivize pharmacy-involved OUD treatment and ultimately slow needed expansion of MOUD services. Increasing IN services requires engaging pharmacies to expand their practice through educational campaigns, along with a commitment to reimburse the cost of medications and related administration activities.

Retention of opioid agonist treatment prescribers across New South Wales, Australia, 2001-2018: Implications for treatment systems and potential impact on client outcomes

BACKGROUND

There has been much research on the efficacy and effectiveness of opioid agonist treatment (OAT), but less on its implementation and sustainability. A challenge internationally has been recruiting and retaining prescribers. This paper aims to characterise the prescribers in terms of OAT prescribing behaviours.

METHODS

Retrospective cohort study in New South Wales, Australia. Participants were 2199 OAT prescribers between 1 st August 2001-19th September 2018.We examined trends in initiation and cessation of OAT prescribers. Adjusted hazard ratios were calculated to estimate prescriber retention, adjusting for year of initiation, practice type, client load and treatment prescribed.

RESULTS

The rate of prescribers ceasing OAT prescribing has been increasing over time: a prescriber who initiated between 2016-2017 had over four times the risk of cessation compared with one who initiated before 2001, AHR: 4.77; [3.67-6.21]. The highest prescriber cessation rate was in prescribers who had prescribed for shorter time periods. The annual percentage of prescribers who ceased prescribing among those who prescribed for ≤5 years increased from 3% in 2001 to 20 % in 2017. By 2017 more prescribers were discontinuing prescribing than new prescribers were starting. Approximately 87 % (n = 25,167) of OAT clients were under the care of 20 % of OAT prescribers (n = 202); half had been prescribing OAT for 17+ years.

CONCLUSIONS

OAT prescribing is increasingly concentrated in a small group of mature prescribers, and new prescribers are not being retained. There is a need to identify and respond to the reasons that contribute to newer prescribers to cease prescribing and put in place strategies to increase retention and broaden the base of doctors involved in such prescribing.

Community pharmacy-based injectable naltrexone service delivery models and best practices

BACKGROUND

Opioid use disorder (OUD) is a major public health issue in the United States. Medications for OUD (MOUD), which combines the use of approved medications with counseling and behavioral therapies, represents an evidence-based approach to treat individuals living with an OUD. However, MOUD has not kept up with increased demand and new treatment approaches are needed. One approach is injectable naltrexone, an approved and effective MOUD treatment, provided by pharmacists, who are more geographically accessible and have legal authority to administer it in some states.

OBJECTIVES

To explore how different community pharmacists provide injectable naltrexone treatment and identify best practices.

METHODS

An exploratory sequential mixed-methods design was used to investigate pharmacy-based naltrexone injection practices, involving a pharmacist questionnaire and interviews with pharmacists, prescribers, and community stakeholders. An inductive/iterative content analysis approach, guided by an initial straw model, was used to identify and explore conceptual categories for the interviews.

RESULTS

The final sample included 68 pharmacy surveys and 14 total interviews with pharmacists (n = 9), prescribers (n = 3), and community stakeholders (n = 2). Pharmacies providing naltrexone injections reported administering over 700 injections in the past year. Interviews revealed benefits and barriers to pharmacist-provided injections and the importance of the prescriber-pharmacist relationship in OUD treatment. Three pharmacy treatment delivery models were identified, compared to the initial straw model, and informed development of a best practices checklist for community pharmacies interested in establishing or expanding a naltrexone injection service.

CONCLUSIONS

The study demonstrates how community pharmacies developed and implemented a naltrexone injection service. Pharmacists' and prescribers' feedback clearly suggests an untapped interest, as well as resources, in realizing pharmacists' roles as providers of injectable naltrexone treatment. Implementation research could inform the development and evaluation of an intervention based on these best practices to further explore the utility of community pharmacy-based naltrexone injection services.

Comparison of buprenorphine and methadone in the management of maternal opioid use disorder in full term pregnancies

Objectives To compare pregnancy outcomes with medication assisted treatment using. methadone or buprenorphine in term mothers with opioid use disorder. Methods A cohort of women receiving medication assisted treatment with either methadone or buprenorphine were identified from delivery records over a 10-year period. Women were excluded with delivery <37 weeks, multiple gestations, or a known anomalous fetus. Maternal demographics, medications, mode of delivery, birthweight, newborn length of stay, and neonatal abstinence syndrome were extracted. The study was IRB approved and a p-value of <0.05 was significant. Results There were 260 women, 140 (53.8%) with methadone use and 120 (46.2%) with buprenorphine use. Groups were similar for maternal age, race, parity, homeless rate, tobacco use, mode of delivery and incidence of neonatal abstinence syndrome. The methadone group had a lower mean newborn birthweight (2874±459 g) and a greater incidence of low birth weight (11.4%) than the buprenorphine group (3282±452 g; p<0.001 and 2.5%; p=0.006). The incidence of neonatal abstinence syndrome was similar between groups (97% methadone vs. 92.5% buprenorphine; p=0.08). The methadone group had a longer newborn length of stay (11.4+7.4 days) and more newborn treatment with morphine (44.6%) than the buprenorphine group (8.2+4.4 days; p<0.001 and 24.2%; p<0.001). Maternal methadone use was an independent predictor for a newborn length of hospital stay >7 days (OR 3.61; 95% confidence interval 1.32-9.86; p=0.01). Conclusions Medication assisted treatment favors buprenorphine use when compared to. methadone with an increased birthweight, reduced need for newborn treatment, and a shorter newborn length of stay in term infants.

Frequency of health-care utilization by adults who use illicit drugs: a systematic review and meta-analysis

AIMS

To summarize evidence on the frequency and predictors of health-care utilization among people who use illicit drugs.

DESIGN

Systematic search of MEDLINE, EMBASE and PsychINFO for observational studies reporting health-care utilization published between 1 January 2000 and 3 December 2018. We conducted narrative synthesis and meta-analysis following a registered protocol (identifier: CRD42017076525).

SETTING AND PARTICIPANTS

People who use heroin, powder cocaine, crack cocaine, methamphetamine, amphetamine, ecstasy/3,4-methyl​enedioxy​methamphetamine (MDMA), cannabis, hallucinogens or novel psychoactive substances; have a diagnosis of 'substance use disorder'; or use drug treatment services.

MEASUREMENTS

Primary outcomes were the cumulative incidence (risk) and rate of care episodes in three settings: primary care, hospital admissions (in-patient) and emergency department (ED).

FINDINGS

Ninety-two studies were included, 84% from North America and Australia. Most studies focused on people using heroin, methamphetamine or crack cocaine, or who had a diagnosis of drug dependence. We were able to conduct a meta-analysis of rates across 25 studies reporting ED episodes and 25 reporting hospital admissions, finding pooled rates of 151 [95% confidence interval (CI) = 114-201] and 41 (95% CI = 30-57) per 100 person-years, respectively; on average 4.8 and 7.1 times more often than the general population. Heterogeneity was very high and was not explained by drugs used, country of study, recruitment setting or demographic characteristics. Predictors of health-care utilization were consistent across studies and included unstable housing, drug injection and mental health problems. Opioid substitution therapy was consistently associated with reduced ED presentation and hospital admission. There was minimal research on health-care utilization by people using ecstasy/MDMA, powder cocaine, hallucinogens or novel psychoactive substances.

CONCLUSIONS

People who use illicit drugs are admitted to emergency department or hospital several times more often than the general population.

Opioid use and schizophrenia

PURPOSE OF REVIEW

To summarize the current literature regarding comorbid schizophrenia and opioid use disorder (OUD).

RECENT FINDINGS

Epidemiological evidence is unclear on whether patients with schizophrenia have a higher rate of OUD. Patients with OUD have been shown to have a higher risk of developing schizophrenia. However, it is clear that patients with both schizophrenia and OUD are less likely to receive standard of care including medication-assisted treatment (MAT) for opiate use disorder and have worse outcomes compared with patients with schizophrenia who do not abuse opioids. OUD significantly increases the risk of converting patients from prodromal schizophrenia states to schizophrenia or schizoaffective disorder. Shared pathophysiology involving the kappa opioid receptor may help explain the relationships between schizophrenia and OUD. Second-generation antipsychotics, long-acting injectables, and MAT for OUD should be utilized in a dual-diagnosis and treatment approach for patients with schizophrenia and OUD.

SUMMARY

Exploration into the relationship between schizophrenia and opiate abuse is still in its infancy and requires a significant amount of future attention to clarify the epidemiology of this comorbidity, neurobiological relationship, shared genetic underpinnings, and possible treatments for both the psychotic symptoms and substance abuse.

Buprenorphine Treatment for Opioid Use Disorder in Community-Based Settings: Outcome Related to Intensity of Services and Urine Drug Test Results

Background and Objectives

Variables contributing to the outcome of buprenorphine treatment for opiate use disorder have been studied, including patient characteristics and the treatment approach applied. It is also valuable to study the types of clinical facilities that can affect outcome.

Methods

We evaluated patients (N = 20 993) in 573 facilities where buprenorphine was prescribed. Urine drug test results were analyzed for those (N = 13 281) who had buprenorphine prescribed at least twice in the period January 2015 through June 2017. Facilities were divided into three categories: medication management (MM) only, limited psychosocial (LP) therapy, and recovery‐oriented (with more extensive counseling and a 12‐step orientation) (RO).

Results

Urine drug tests negative for other opioids at the time of the second buprenorphine prescription were 34% for MM, 56% for LP, and 62% for RO (P < .001). A comparison was made between the most recent and the established patients at the facilities. The decrement in urinalyses positive for other opioids in this latter comparison was 3% for MM, 7% for LP, and 23% for RO (P < .001).

Discussion and Conclusions

In a large sample of community settings, buprenorphine patients’ urinalyses positive for opioids can vary considerably across treatment facilities, and more intensive recovery orientation may yield a better outcome in terms of secondary opioid use.

Scientific Significance

The majority of buprenorphine patients are treated in community facilities. It is important that research be done by facility type in such settings in order to plan for optimal treatment. (© 2020 The Authors. The American Journal on Addictions published by Wiley Periodicals, Inc.;00:00–00)

Systematic Review of Criminal and Legal Involvement After Substance Use and Mental Health Treatment Among Veterans: Building Toward Needed Research

Evidence indicates that substance use and mental health treatment is often associated with reduced criminal activity. The present systematic review examined this association among military veterans, and aimed to provide a comprehensive summary of needed research to further contribute to reduced criminal activity among veterans. This systematic review was derived from a scoping review that mapped existing research on justice-involved veterans' health. For the current systematic review, a subset of 20 publications was selected that addressed the question of whether criminal activity declines among veterans treated for substance use and mental health disorders. Generally, veterans improved on criminal outcomes from pre- to post-treatment for opioid use, other substance use, or mental health conditions, and more sustained treatment was associated with better outcomes. This occurred despite high rates of criminal involvement among veterans prior to entering treatment. Needed are substance use and mental health treatment studies that include women justice-involved veterans, follow criminally-active veterans for longer periods of time, and use validated and reliable measures of criminal activity with fully transparent statistical procedures. Future randomized trials should evaluate new treatments against evidence-based treatments (versus no-treatment control conditions). Subsequent studies should examine how to link veterans to effective treatments, facilitate sustained treatment engagement, and ensure the availability of effective treatments, and examine mechanisms (mediators and moderators) that explain the association of treatment with reduced criminal activity among veterans. Best practices are needed for reducing criminal activity among the minority of justice-involved veterans who do not have diagnosed substance use and/or mental health disorders.

Methamphetamine use drives decreases in viral suppression for people living with HIV released from a large municipal jail: Results of the LINK LA clinical trial

BACKGROUND

People living with HIV (PLWH) often experience decreases in HIV viral suppression (VS) after release from jail. The Linking Inmates to Care in LA (LINK LA) peer navigation intervention helped maintain VS 12 months after release from jail compared to standard of care. In this study, we analyzed correlates of substance use and tested whether substance use was an independent correlate of decreased VS in LINK LA participants.

METHODS

We analyzed LINK LA data collected at baseline, 3, and 12 months. We defined high-risk drug use as any reported methamphetamine, cocaine, or opioid use in the 30 days prior to a study visit (or jail entry at baseline). We used generalized linear mixed models to test associations of sociodemographic variables with type of substance used, and we tested correlates of VS while controlling for time, the intervention, and their interaction.

RESULTS

At baseline (n = 356), 71% of participants reported high-risk drug use: 58%, methamphetamine; 17%, cocaine; 7%, heroin; and 4%, prescription opioids. Non-Hispanic Whites and those younger than 35 were most likely to use methamphetamine; Blacks were most likely to use cocaine; people who inject drugs were most likely to use opioids. Participants who used high-risk drugs had 53% lower adjusted odds than non-users of maintaining VS (AOR 0.47, 95% CI 0.31-0.70, p < 0.001).

CONCLUSION

High-risk drug use, dominated by methamphetamine use, independently correlated with decreased VS among recently incarcerated PLWH. Improving HIV care continuum outcomes among populations leaving jail requires attention to efforts to address high-risk drug use.

Temporal associations between medication adherence for patients with schizophrenia and opioid dependence: A 17-year Canadian Cohort Study

The current study investigated whether a previously reported beneficial effect of methadone maintenance therapy (MMT) on antiretroviral adherence is also present in relation to antipsychotic treatment for schizophrenia. Administrative data were linked over a 17-year period for 1996 people who were dually diagnosed with schizophrenia and opioid dependence and, as an indicator of further marginalization, experienced at least one episode of correctional supervision in British Columbia. Adherence was estimated using the medication possession ratio (MPR ≥ 0.80), calculated in each 120-day period beginning with the first date of concurrent use of MMT and antipsychotic medication. Generalized Estimating Equations were used to estimate the association between independent and dependent variables. The probability of antipsychotic adherence doubled in periods that were preceded by a period of MMT adherence (AOR: P: 2.07; 95% CI: 1.90-2.26). Subgroup and sensitivity analyses yielded results similar to those derived through the primary analysis, examining: conviction history; length of follow-up; initiation of MMT prior to antipsychotic induction; excluding participants who died during the study period; and restricted to participants who received methadone exclusively as part of a MMT program. Despite a strong temporal association between MMT and antipsychotic adherence, overall MPRs for both prescriptions remained <0.50 throughout the study period. Antipsychotic adherence was more than twice as likely following periods of adherence to MMT among dually-diagnosed patients. Research is needed to identify the conditions responsible for MMT adherence, and to further clarify the relationship between opioid agonist treatment and antipsychotic pharmacotherapy in this vulnerable and under-studied population.

Criminal justice outcomes over 5 years after randomization to buprenorphine-naloxone or methadone treatment for opioid use disorder

AIMS

To compare long-term criminal justice outcomes among opioid-dependent individuals randomized to receive buprenorphine or methadone.

DESIGN, SETTING AND PARTICIPANTS

A 5-year follow-up was conducted in 2011-14 of 303 opioid-dependent participants entering three opioid treatment programs in California, USA in 2006-09 and randomized to receive either buprenorphine/naloxone or methadone.

INTERVENTION AND COMPARATOR

Participants received buprenorphine/naloxone (BUP; n = 179) or methadone (MET; n = 124) for 24 weeks and then were tapered off their treatment over ≤ 8 weeks or referred for ongoing clinical treatment. Midway through the study, the randomization scheme was switched from 1 : 1 BUP : MET to 2 : 1 because of higher dropout in the BUP arm.

MEASUREMENTS

Study outcomes included arrests and self-reported incarceration. Predictors included randomization condition (buprenorphine versus methadone), age, gender, race/ethnicity, use of cocaine, drug injection in the 30 days prior to baseline and study site. Treatment status (buprenorphine, methadone, none) during follow-up was included as a time-varying covariate.

FINDINGS

There was no significant difference by randomization condition in the proportion arrested (buprenorphine: 55.3%, methadone: 54.0%) or incarcerated (40.9%, 47.3%) during follow-up. Among methadone-randomized individuals, arrest was less likely with methadone treatment (0.50, 0.35-0.72) during follow-up (relative to no treatment) and switching to buprenorphine had a lower likelihood of arrest than those receiving no treatment (0.39, 0.18-0.87). Among buprenorphine-randomized individuals, arrest was less likely with receipt of buprenorphine (0.49, 0.33-0.75) during follow-up and switching to methadone had a similar likelihood of arrest as methadone-randomized individuals receiving no treatment. Likelihood of arrest was also negatively associated with older age (0.98, 0.96-1.00); it was positively associated with Hispanic ethnicity (1.63, 1.04-2.56), cocaine use (2.00, 1.33-3.03), injection drug use (2.19, 1.26-3.83), and study site.

CONCLUSIONS

In a US sample of people treated for opioid use disorder, continued treatment with either buprenorphine or methadone was associated with a reduction in arrests relative to no treatment. Cocaine use, injection drug use, Hispanic ethnicity and younger age were associated with higher likelihood of arrest.

Treatment of substance use disorders with co-occurring severe mental health disorders

PURPOSE OF REVIEW

To provide an update of treatment for substance use in patients with co-occurring substance use disorders (SUD) and mental health disorders (dual diagnosis) with a focus on both pharmacological and psychosocial interventions.

RECENT FINDINGS

A total of 1435 abstracts were identified, of which we selectively reviewed 43 for this narrative review. There is emerging evidence, both clinical and neurobiological, that clozapine is a more efficacious antipsychotic in treatment of individuals with schizophrenia and SUD. The use of depot atypical antipsychotic paliperidone palmitate in this population is also promising. Although valproate remains the treatment of choice in individuals with bipolar disorder and SUD, present evidence suggests that lithium and quetiapine may not be effective in this population. Naltrexone is the most effective anticraving agent in individuals with severe mental illness (SMI) and comorbid alcohol use disorders. The use of opioid substitution therapy in individuals with SMI and comorbid opioid use disorders is also associated with favorable outcomes. Varenicline shows promise in patients with SMI who smoke tobacco. Psychosocial interventions should be instituted early in the course of treatment. They should ideally be high intensity and based on established therapies used for SUD.

SUMMARY

The paucity of systematic studies in individuals with co-occurring mental health disorders and SUD remains a concern, given the enormous burden that they pose. However, there are a number of studies which have evaluated interventions, both psychosocial and pharmacological, which show promise and can guide clinical practice.

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.

Comorbid opioid use is undertreated among forensic patients with schizophrenia

BACKGROUND

Substance use disorders are associated with poorer clinical outcomes in patients with schizophrenia. There is no specific treatment for amphetamine or cannabis use disorder, but methadone and buprenorphine are used as replacement therapy in the treatment of opioid dependence. Our aim was to study whether patients with schizophrenia have received opioid replacement therapy for their opioid use disorder.

METHODS

The study sample consisted of 148 individuals diagnosed with schizophrenia who were in involuntary psychiatric treatment as forensic patients in Finland in 2012. The proportion of the study sample with comorbid opioid use disorder having received opioid replacement therapy prior to their forensic psychiatric treatment was compared to the available information of opioid dependent patients in general. The data were collected from forensic examination statements, patient files and other medical registers retrospectively.

RESULTS

Of the study sample, 15.6% (23/148) had a history of opioid use disorder, of whom 8.7% (2/23) had received opioid replacement treatment (95% confidence interval (Cl): 1.1-28.0), even though opioid use disorder had been diagnosed in the treatment system. According the available information the corresponding proportion among patients with opioid use disorder and using substance use disorder services was 30.4% (565/1860, 95% Cl: 28.3-32.5). The fraction of patients receiving opioid replacement therapy was significantly lower among patients with schizophrenia (p = 0.022).

CONCLUSIONS

Opioid replacement therapy was seldom used among schizophrenia patients who were later ordered to involuntary forensic psychiatric treatment. More attention should be paid to the possible use of opioids when planning treatment for patients with schizophrenia.

TRIAL REGISTRATION

Our study is not a randomized controlled trial (but a register-based study); thus the trial registration is not applicable.

Using routinely collected data to understand and predict adverse outcomes in opioid agonist treatment: Protocol for the Opioid Agonist Treatment Safety (OATS) Study

INTRODUCTION

North America is amid an opioid use epidemic. Opioid agonist treatment (OAT) effectively reduces extramedical opioid use and related harms. As with all pharmacological treatments, there are risks associated with OAT, including fatal overdose. There is a need to better understand risk for adverse outcomes during and after OAT, and for innovative approaches to identifying people at greatest risk of adverse outcomes. The Opioid Agonist Treatment and Safety study aims to address these questions so as to inform the expansion of OAT in the USA.

METHODS AND ANALYSIS

This is a retrospective cohort study using linked, routinely collected health data for all people seeking OAT in New South Wales, Australia, between 2001 and 2017. Linked data include hospitalisation, emergency department presentation, mental health diagnoses, incarceration and mortality. We will use standard regression techniques to model the magnitude and risk factors for adverse outcomes (eg, mortality, unplanned hospitalisation and emergency department presentation, and unplanned treatment cessation) during and after OAT, and machine learning approaches to develop a risk-prediction model.

ETHICS AND DISSEMINATION

This study has been approved by the Population and Health Services Research Ethics Committee (2018HRE0205). Results will be reported in accordance with the REporting of studies Conducted using Observational Routinely-collected health Data statement.

Trends and disparities in receipt of pharmacotherapy among pregnant women in publically funded treatment programs for opioid use disorder in the United States

OBJECTIVE

To describe differences in geographic, demographic, treatment, and substance use characteristics by pharmacotherapy receipt among pregnant women entering publically funded treatment for opioid use disorder (OUD) in the United States.

METHODS

1996 to 2014 Treatment Episode Data Set-Admissions data from pregnant admissions with OUD, defined as reporting opioids as the primary substance of use leading to the treatment episode, were analyzed for this cross-sectional study. The proportion of all pregnant admissions with OUD who received pharmacotherapy was calculated by year and U.S. census region. Trends across time were assessed using the Cochrane-Armitage Trend test. Associations between demographic, substance use, and treatment characteristics and pharmacotherapy receipt were assessed using Chi-square tests and multivariable logistic regression.

RESULTS

The proportion of pregnant admissions where opioids were the primary substance of use increased from 16.9% to 41.6% during the study period, while the proportion of pregnant admissions with OUD who received pharmacotherapy remained relatively unchanged at around 50%. Overall, pharmacotherapy recipients were generally older and white, more likely to receive treatment in an outpatient setting, be self-referred, and report heroin as the primary substance, daily substance use, and intravenous drug use, and less likely to have a co-occurring psychiatric problem compared to those who did not receive pharmacotherapy. Regional differences in pharmacotherapy utilization exist; the South consistently had the fewest pregnant admissions with OUD receiving pharmacotherapy.

CONCLUSION

Although the proportion of pregnant admissions to substance use treatment centers with OUD has increased since the mid-1990s, the proportion receiving pharmacotherapy has not changed. Significant variations in pharmacotherapy utilization exist by geography and demographic, substance use and treatment characteristics. Utilization of pharmacotherapy at publically funded treatment centers providing care for pregnant women with OUD should be expanded.
