Effectiveness of Scotland's National Naloxone Programme for reducing opioid-related deaths: a before (2006-10) versus after (2011-13) comparison

The Impact of a Peer-Navigator Program on Naloxone Distribution and Buprenorphine Utilization in the Emergency Department

Objectives: In recent years many emergency departments (EDs) have adopted interventions to help patients with opioid use disorder (OUD), particularly buprenorphine initiation and ED-based peer recovery support. There are limited data on the impact of peer navigators on provider naloxone kit distribution and buprenorphine utilization. We aimed to examine the impact of a peer recovery program on naloxone kit distribution and buprenorphine administration. Methods: This was a retrospective study analyzing the change in naloxone kits distributed as well as buprenorphine administrations. Data on naloxone kit and buprenorphine administrations was generated every month between November 2017 and February 2021. Time periods were as follows: implementation of guidelines for buprenorphine and naloxone kits, initiation of the navigator program, and first wave of COVID-19. Numbers of naloxone kits distributed and buprenorphine administrations per month were computed. Results: Between November 2017 and December 2020, there was a significant increase overtime among the 238 naloxone kits distributed (p < 0.0001). Between implementation of guidelines and introduction of peer navigators, there were 49 kits distributed, compared to an increase overtime among 235 kits when the navigator program began (p = 0.0001). There was also a significant increase overtime among 1797 administrations of buprenorphine (p < 0.0001). Administrations increased by 22.4% after implementation of the navigator program-a total of 787 compared to 643 post guideline (p = 0.007). Conclusion: Peer recovery support programs for patients with OUD can have an impact on administration of naloxone kits and buprenorphine. Future studies should determine whether these programs can cause a long-term culture change in the ED.

Targeting community-based naloxone distribution using opioid overdose death rates: A descriptive analysis of naloxone rescue kits and opioid overdose deaths in Massachusetts and Rhode Island

BACKGROUND

Rates of fatal opioid overdose in Massachusetts (MA) and Rhode Island (RI) far exceed the national average. Community-based opioid education and naloxone distribution (OEND) programs are effective public health interventions to prevent overdose deaths. We compared naloxone distribution and opioid overdose death rates in MA and RI to identify priority communities for expanded OEND.

METHODS

We compared spatial patterns of opioid overdose fatalities and naloxone distribution through OEND programs in MA and RI during 2016 to 2019 using public health department data. The county-level ratio of naloxone kits distributed through OEND programs per opioid overdose death was estimated and mapped to identify potential gaps in naloxone availability across geographic regions and over time.

RESULTS

From 2016 to 2019, the statewide community-based naloxone distribution to opioid overdose death ratio improved in both states, although more rapidly in RI (from 11.8 in 2016 to 35.6 in 2019) than in MA (from 12.3 to 17.2), driven primarily by elevated and increasing rates of naloxone distribution in RI. We identified some urban/non-urban differences, with higher naloxone distribution relative to opioid overdose deaths in more urban counties, and we observed some counties with high rates of overdose deaths but low rates of naloxone kits distributed through OEND programs.

CONCLUSIONS

We identified variations in spatial patterns of opioid overdose fatalities and naloxone availability, and these disparities appeared to be widening in some areas over time. Data on the spatial distribution of naloxone distribution and opioid overdose deaths can inform targeted, community-based naloxone distribution strategies that optimize resources to prevent opioid overdose fatalities.

Effectiveness and implementability of state-level naloxone access policies: Expert consensus from an online modified-Delphi process

BACKGROUND

Naloxone distribution, a key global strategy to prevent fatal opioid overdose, has been a recent target of legislation in the U.S., but there is insufficient empirical evidence from causal inference methods to identify which components of these policies successfully reduce opioid-related harms. This study aimed to examine expert consensus on the effectiveness and implementability of various state-level naloxone policies.

METHODS

We used the online ExpertLens platform to conduct a three-round modified-Delphi process with a purposive sample of 46 key stakeholders (advocates, healthcare providers, human/social service practitioners, policymakers, and researchers) with naloxone policy expertise. The Effectiveness Panel (n = 24) rated average effects of 15 types of policies on naloxone pharmacy distribution, opioid use disorder (OUD) prevalence, nonfatal opioid-related overdoses, and opioid-related overdose mortality. The Implementation Panel (n = 22) rated the same policies on acceptability, feasibility, affordability, and equitability. We compared ratings across policies using medians and inter-percentile ranges, with consensus measured using the RAND/UCLA Appropriateness Method Inter-Percentile Range Adjusted for Symmetry technique.

RESULTS

Experts reached consensus on all items. Except for liability protections and required provision of education or training, experts perceived all policies to generate moderate-to-large increases in naloxone pharmacy distribution. However, only three policies were expected to yield substantive decreases on fatal overdose: statewide standing/protocol order, over-the-counter supply, and statewide "free naloxone." Of these, experts rated only statewide standing/protocol orders as highly affordable and equitable, and unlikely to generate meaningful population-level effects on OUD or nonfatal opioid-related overdose. Across all policies, experts rated naloxone prescribing mandates relatively lower in acceptability, feasibility, affordability, and equitability.

CONCLUSION

Experts believe statewide standing/protocol orders are an effective, implementable, and equitable policy for addressing opioid-related overdose mortality. While experts believe many other broad policies are effective in reducing opioid-related harms, they also believe these policies face implementation challenges related to cost and reaching vulnerable populations.

Changes in overdose knowledge and attitudes in an incarcerated sample of people living with HIV

PURPOSE

The purpose of this paper is to present evaluation results. People exiting incarceration who use opioids are at an elevated risk for overdose following release. People living with HIV (PLWH) who use drugs are also at increased overdose risk. Overdose education and naloxone distribution (OEND) is an effective community-based intervention, but few OEND programs have been evaluated in a correctional setting and none have specifically targeted PLWH.

DESIGN/METHODOLOGY/APPROACH

An OEND pilot program was implemented in the Philadelphia jail from December 2017 to June 2019. OEND was provided through an HIV case management program and naloxone given at release. Participants (n = 68) were assessed for changes in overdose knowledge and beliefs in their ability to respond to an overdose from baseline to one month later while still incarcerated. Other demographic variables were assessed via publicly available records and case manager chart abstraction.

FINDINGS

A total of 120 incarcerated PLWH were OEND trained; 68 (56.7%) were still incarcerated one month later and received post-tests. The 68-person sample was predominantly male (79.4%) and Black (64.7%). One-fifth reported heroin use, a third reported cocaine use and nearly 2/3 reported use of any illegal drug on date of arrest. Among these 68, overdose knowledge and overdose attitudes improved significantly (p = 0.002 and p < 0.001, respectively).

ORIGINALITY/VALUE

OEND in correctional settings is feasible and knowledge and overdose attitudes improved significantly from baseline. OEND programs should be implemented within the general population of incarcerated people but, as with PLWH, can be extended to other vulnerable populations within correctional settings, such as persons with mental health conditions and a history of homelessness.

'Keeping a lid on it': Exploring 'problematisations' of prescribed medication in prisons in the UK

BACKGROUND

The non-medical use of prescription medication and risk of diversion have become policy and practice concerns within prison settings in the UK. These issues have been highlighted by the Advisory Council on the Misuse of Drugs, Her Majesty's Inspectorate of Prisons and Her Majesty's Prison and Probation Service (2019) prison drugs strategy. In 2019, new prescribing guidance was issued by the Royal College of General Practitioners for clinicians working within prison settings.

METHODS

Informed by Bacchi's (2009) What's the problem represented to be? framework, the ways in which the 'problem' of prescribed medication in prisons have been represented is interrogated through an analysis of the prescribing guidance framework for clinicians working in prisons.

RESULTS

Restrictive prescribing practices are recommended as a solution to the 'problem' of diversion and misuse of prescribed medication. Prescribers are advised to consider de-prescribing, non-pharmacological treatments and alternative prescriptions with less diversionary potential. They are represented as responsible for the 'problems' that prescribed medication bring to prisons. The guidance is underpinned by the assumption that prescribers lack experience, knowledge and skills in prison settings. People serving prison sentences are assumed to be 'untrustworthy' and their symptoms treated with suspicion. This representation of the 'problem' has a number of effects including the possibility of increasing drug-related harm, damaging the patient-doctor relationship and disengagement from healthcare services.

CONCLUSION

The representation of prescribed medication as problems of diversion and prescribing practices inhibits alternative representations of the problem which would inform different policy directions including improvements to regime and healthcare provision and would include a range of practitioners in prison settings to address the 'problem' more holistically.

Benefits and barriers associated with take-home-naloxone in the view of Italian service providers

Purpose

Spanning almost 30 years, Italy’s experience with take-home-naloxone (THN) provides an interesting case study on the international scene because of its specific history, regulation and trends in overdose (OD) rates. Accordingly, this study aims to contribute to the evidence base for THN and its delivery in a different setting.

Design/methodology/approach

The study focuses on service providers’ perceptions of the benefits, risks and barriers associated with THN provision. Data was collected using a mixed-methods approach as follows: an online structured questionnaire (no. of respondents = 63) and two focus groups (no. of total participants = 18).

Findings

Findings show that service providers believe the benefits of THN far outweigh the risks and accrue to services, as well as users. The study also suggests that the barriers in Italy are mostly ideological and political, and illustrates how resistance to administering THN can re-emerge when ODs are no longer a social emergency. Furthermore, the study found that health and social workers have different attitudes which are also reflected at the level of public and private services, thereby shaping slightly different models of THN supply.

Originality/value

The study suggests that barriers associated to THN are more ideological and political rather than concrete, which explains why, even where it seems long established, can easily re-emerge once ODs are no longer a social emergency.

Emotional reactions of trained overdose responders who use opioids following intervention in an overdose event

Background: Our aim was to explore emotional reactions to intervening in an overdose event from the perspective of individuals who use opioids (peer responders). In addition, we were interested in the impact this experience may have on peer responders' feelings about helping in an overdose situation in the future. Methods: For this qualitative sub-study of a randomized controlled trial (RCT), data from 61 interviews were analyzed thematically using an inductive approach. Results: Peer responders had diverse emotional reactions to the overdose event. These ranged from a sense of pride and other positive feelings associated with their ability to help to ambivalence about being involved in situations perceived as challenging and burdensome. There were few reports of the overdose event as an exclusively negative experience. Many peer responders perceived it as their duty to use naloxone again if required. However, some had ambivalent feelings toward this responsibility, which may be related to negative experiences with previous intervention efforts. Conclusions: The capacity of people who use opioids to help reduce the harms associated with opioid overdose is experienced as empowering by some. Nonetheless, engaging peer responders in strategies to reduce opioid-related mortality should be coupled with appropriate resources to process their experiences and emotional responses.

The impact of the opioid crisis on U.S. state prison systems

BACKGROUND

Prior studies have documented limited use of medications to treat opioid use disorders (OUD) for people incarcerated within state prisons in the United States. Using the framework of the criminal justice OUD service cascade, this study interviewed representatives of prison systems in states most heavily impacted by opioid overdose regarding the provision of medications for OUD (MOUD).

METHODS

A stratified sampling strategy included states with high indicators of opioid-overdose deaths. Two sampling strata targeted states with: 1) OUD overdose rates significantly higher than the per capita national average; or 2) high absolute number of OUD overdose fatalities. Interviews were completed with representatives from 21 of the 23 (91%) targeted states in 2019, representing 583 prisons across these states. Interviews assessed service provision across the criminal justice OUD service cascade, including OUD screening, withdrawal management, MOUD availability and provision, overdose prevention, re-entry services, barriers, and needs for training and technical assistance.

RESULTS

MOUD (buprenorphine, methadone, or naltrexone) was available in at least one prison in approximately 90% of the state prison systems and all three medications were available in at least one prison in 62% of systems. However, MOUD provision was limited to subsets of prisons within these systems: 15% provided buprenorphine, 9% provided methadone, 36% provided naltrexone, and only 7% provided all three. Buprenorphine and methadone were most frequently provided to pregnant women or individuals already receiving these at admission, whereas naltrexone was primarily used at release. Funding was the most frequently cited barrier for all medications.

CONCLUSION

Study findings yield a complex picture of how, when, and to whom MOUD is provided across prisons within prison systems in states most heavily impacted by opioid overdose in the United States and have implications for expanding availability.

Pharmacist attitudes and provision of harm reduction services in North Carolina: an exploratory study

BACKGROUND

Pharmacists are among the most accessible healthcare providers in the United States and uniquely positioned to provide harm reduction services. The availability of pharmacy-based harm reduction services and pharmacist attitudes toward delivering these services have been understudied to date. We examine North Carolina (NC) pharmacists' experiences with and attitudes about harm reduction services and explore differences between rural and urban pharmacists.

METHODS

A convenience sample of NC pharmacists participated in an anonymous, online survey regarding harm reduction services: non-prescription syringe sales; naloxone dispensing; and human immunodeficiency virus (HIV) and hepatitis C virus (HCV) screening. Urban-rural differences were analyzed using Pearson's chi-square or Fisher's exact tests. Open-ended responses were analyzed thematically.

RESULTS

Three hundred pharmacists responded to the survey; 68 (23%) practiced in rural counties. Dispensing non-prescription syringes and naloxone at least occasionally was reported by 77% (n = 231) and 88% (n = 263) pharmacists, respectively. Pharmacy-delivered HIV or HCV screening was rare. Urban pharmacists dispensed naloxone more frequently than rural pharmacies (p = 0.04). Only 52% of pharmacists agreed that persons who inject drugs should always be allowed to buy non-prescription syringes. Rural pharmacists' attitudes toward harm reduction services for persons who inject drugs were statistically, though marginally, less supportive when compared to urban pharmacists' attitudes. The most common barrier to non-prescription syringe access was requiring patients to provide proof of prescription injection medication use, which 21% of pharmacists reported was required by their pharmacy's policy on non-prescription syringe sales.

CONCLUSIONS

Although most pharmacies distributed naloxone and sold non-prescription syringes, pharmacy store policies and personal beliefs inhibited naloxone and non-prescription syringe dispensing. NC community pharmacies infrequently offer HIV and HCV screening. Paired with disseminating the evidence of the positive impact of harm reduction on individual and public health outcomes to NC pharmacists, institutional and systems changes to practice and policy may be important to promote harm reduction service availability, particularly for rural NC residents.

The state of harm reduction in prisons in 30 European countries with a focus on people who inject drugs and infectious diseases

BACKGROUND

People who inject drugs are often imprisoned, which is associated with increased levels of health risks including overdose and infectious diseases transmission, affecting not only people in prison but also the communities to which they return. This paper aims to give an up-to-date overview on availability, coverage and policy framework of prison-based harm reduction interventions in Europe.

METHODS

Available data on selected harm reduction responses in prisons were compiled from international standardised data sources and combined with a questionnaire survey among 30 National Focal Points of the European Monitoring Centre for Drugs and Drug Addiction to determine the level of availability, estimated coverage and policy framework of the interventions.

RESULTS

Information about responses to health harms in prisons is limited and heterogeneous. Cross-country comparability is hampered by diverging national data collection methods. Opioid substitution treatment (OST) is available in 29 countries, but coverage remains low (below 30% of people in need) in half of the responding countries. Needle and syringe programmes, lubricant distribution, counselling on safer injecting and tattooing/piercing are scarcely available. Testing for infectious diseases is offered but mostly upon prison entry, and uptake remains low in about half of the countries. While treatment of infections is mostly available and coverage is high for human immunodeficiency virus (HIV) and tuberculosis, hepatitis B and C treatment are less often provided. Health education as well as condom distribution is usually available, but provision remains low in nearly half of the countries. Post-release linkage to addiction care as well as to treatment of infections is available in a majority of countries, but implementation is often partial. Interventions recommended to be provided upon release, such as OST initiation, take-home naloxone and testing of infections, are rarely provided. While 21 countries address harm reduction in prison in national strategic documents, upon-release interventions appear only in 12.

CONCLUSIONS

Availability and coverage of harm reduction interventions in European prisons are limited, compared to the community. There is a gap between international recommendations and 'on-paper' availability of interventions and their actual implementation. Scaling up harm reduction in prison and throughcare can achieve important individual and public-health benefits.

Saving Lives: The Veterans Health Administration (VHA) Rapid Naloxone Initiative

BACKGROUND

The United States is in the midst of an opioid epidemic within the COVID-19 pandemic, and veterans are twice as likely to die from accidental overdose compared to non-veterans. This article describes the Veterans Health Administration (VHA) Rapid Naloxone Initiative, which aims to prevent opioid overdose deaths among veterans through (1) opioid overdose education and naloxone distribution (OEND) to VHA patients at risk for opioid overdose, (2) VA Police naloxone, and (3) select automated external defibrillator (AED) cabinet naloxone.

METHODS

VHA has taken a multifaceted, theory-based approach to ensuring the rapid availability of naloxone to prevent opioid overdose deaths. Strategies targeted at multiple levels (for example, patient, provider, health care system) have enabled synergies to speed diffusion of this lifesaving practice.

RESULTS

As of April 2021, 285,279 VHA patients had received naloxone from 31,730 unique prescribers, with 1,880 reported opioid overdose reversals with naloxone; 129 VHA facilities had equipped 3,552 VA Police officers with naloxone, with 136 reported opioid overdose reversals with VA Police naloxone; and 77 VHA facilities had equipped 1,095 AED cabinets with naloxone, with 10 reported opioid overdose reversals with AED cabinet naloxone. Remarkably, the COVID-19 pandemic had minimal impact on naloxone dispensing to VHA patients.

CONCLUSION

The VHA Rapid Naloxone Initiative saves lives. VHA is sharing many of the tools and resources it has developed to support uptake across other health care systems. Health care systems need to work together to combat this horrific epidemic within a pandemic and prevent a leading cause of accidental death (opioid overdose).

Explaining the Differences in Opioid Overdose Deaths between Scotland and England/Wales: Implications for European Opioid Policies

BACKGROUNDS

Between 2009 and 2018, the number of opioid-related deaths (ORDs) in Scotland showed a dramatic increase, whereas in England and Wales, a much lower increase in ORD was seen. This regional difference is remarkable, and the situation in Scotland is worrisome. Therefore, it is important to identify the drivers of ORD in Scotland.

METHODS

A systematic literature review according to PRISMA guidelines was conducted to identify peer-reviewed studies about key drivers for the observed differences in ORDs between Scotland and England/Wales. In addition, non-peer-reviewed reports on nationwide statistical data were retrieved via Google and Google Scholar and analysed to quantify differences in ORD drivers between Scotland and England/Wales.

RESULTS

The systematic review identified some important drivers of ORD, but none of these studies provided direct or indirect comparisons of ORD drivers in Scotland and England/Wales. However, the reports with nationwide statistical data showed important differences in ORD drivers between Scotland and England/Wales, including a higher prevalence of people using opioids in a problematic way (PUOP), more polydrug use in people using drugs in a problematic way (PUDP), a higher age of PUDP, and lower treatment coverage and efficacy of PUDP in Scotland compared to England/Wales, but no regional differences in injecting drug use, incarceration/prison release without treatment, and social deprivation in PUDP.

CONCLUSION

It is concluded that the opioid crisis in Scotland is best explained by a combination of drivers, consisting of a higher population involvement in (problematic) opioid use (notably methadone), relatively more polydrug use (notably benzodiazepines and gabapentinoids), a steeper ageing of the PUOP population in the past 2 decades, and lower treatment coverage and efficacy in Scotland compared to England/Wales. The findings have important consequences for strategies to handle the opioid crisis in Scotland.

Patient perspectives of barriers to naloxone obtainment and use in a primary care, underserved setting: A qualitative study

Background: Gaps in naloxone obtainment and use are not well studied, particularly among minoritized groups. Objective: To describe patient perspectives that serve as barriers to naloxone obtainment and the number of patients who obtained naloxone in a primarily African American population in a primary care, underserved setting. Methods: This qualitative study conducted semi-structured interviews and included 36 adults who were prescribed naloxone at a federally qualified health center using convenience sampling. Participants answered survey questions describing naloxone acceptability, perceived risk for overdose, and barriers to naloxone use. Results: Sixty-nine percent of the patients were Black or African American. The majority of patients attempted to fill their naloxone at a local pharmacy (69%) and reported no difficulties (88%). Five major themes revealed: overall positive views of naloxone because it saves lives; existing knowledge gaps related to indications for naloxone prescription; stigma surrounding receiving a naloxone prescription; inadequacies of the patient education provided; and the role providers play in naloxone receptivity Conclusions: Among a majority African American population, many perceived naloxone to be lifesaving. However, stigmatizing perceptions and inability to recall patient education contribute to a perception of low overdose risk. Further research describing the impact of the opioid epidemic on underrepresented groups is necessary.

Emergency care with lay responders in underserved populations: a systematic review

Objective

To assess the individual and community health effects of task shifting for emergency care in low-resource settings and underserved populations worldwide.

Methods

We systematically searched 13 databases and additional grey literature for studies published between 1984 and 2019. Eligible studies involved emergency care training for laypeople in underserved or low-resource populations, and any quantitative assessment of effects on the health of individuals or communities. We conducted duplicate assessments of study eligibility, data abstraction and quality. We synthesized findings in narrative and tabular format.

Findings

Of 19 308 papers retrieved, 34 studies met the inclusion criteria from low- and middle-income countries (21 studies) and underserved populations in high-income countries (13 studies). Targeted emergency conditions included trauma, burns, cardiac arrest, opioid poisoning, malaria, paediatric communicable diseases and malnutrition. Trainees included the general public, non-health-care professionals, volunteers and close contacts of at-risk populations, all trained through in-class, peer and multimodal education and public awareness campaigns. Important clinical and policy outcomes included improvements in community capacity to manage emergencies (14 studies), patient outcomes (13 studies) and community health (seven studies). While substantial effects were observed for programmes to address paediatric malaria, trauma and opioid poisoning, most studies reported modest effect sizes and two reported null results. Most studies were of weak (24 studies) or moderate quality (nine studies).

Conclusion

First aid education and task shifting to laypeople for emergency care may reduce patient morbidity and mortality and build community capacity to manage health emergencies for a variety of emergency conditions in underserved and low-resource settings.

Periods of altered risk for non-fatal drug overdose: a self-controlled case series

BACKGROUND

Being recently released from prison or discharged from hospital, or being dispensed opioids, benzodiazepines, or antipsychotics have been associated with an increased risk of fatal drug overdose. This study aimed to examine the association between these periods and non-fatal drug overdose using a within-person design.

METHODS

In this self-controlled case series, we used data from the provincial health insurance client roster to identify a 20% random sample of residents (aged ≥10 years) in British Columbia, Canada between Jan 1, 2015, and Dec 31, 2017 (n=921 346). Individuals aged younger than 10 years as of Jan 1, 2015, or who did not have their sex recorded in the client roster were excluded. We used linked provincial health and correctional records to identify a cohort of individuals who had a non-fatal overdose resulting in medical care during this time period, and key exposures, including periods of incarceration, admission to hospital, emergency department care, and supply of medications for opioid use disorder (MOUD), opioids for pain (unrelated to MOUD), benzodiazepines, and antipsychotics. Using a self-controlled case series, we examined the association between the time periods during and after each of these exposures and the incidence of non-fatal overdose with case-only, conditional Poisson regression analysis. Sensitivity analyses included recurrent overdoses and pre-exposure risk periods.

FINDINGS

We identified 4149 individuals who had a non-fatal overdose in 2015-17. Compared with unexposed periods (ie, all follow-up time that was not part of a designated risk period for each exposure), the incidence of non-fatal overdose was higher on the day of admission to prison (adjusted incidence rate ratio [aIRR] 2·76 [95% CI 1·51-5·04]), at 1-2 weeks (2·92 [2·37-3·61]), and 3-4 weeks (1·34 [1·01-1·78]) after release from prison, 1-2 weeks after discharge from hospital (1·35 [1·11-1·63]), when being dispensed opioids for pain (after ≥4 weeks) or benzodiazepines (entire use period), and from 3 weeks after discontinuing antipsychotics. The incidence of non-fatal overdose was reduced during use of MOUD (aIRRs ranging from 0·33 [0·26-0·42] to 0·41 [0·25-0·67]) and when in prison (0·12 [0·08-0·19]).

INTERPRETATION

Expanding access to and increasing support for stable and long-term medication for the management of opioid use disorder, improving continuity of care when transitioning between service systems, and ensuring safe prescribing and medication monitoring processes for medications that reduce respiratory function (eg, benzodiazepines) could decrease the incidence of non-fatal overdose.

The hospital admission profile of people presenting to specialist addiction services with problematic use of alcohol or opioids: A national retrospective cohort study in England

BACKGROUND

Over the past decade in England the rate of alcohol and opioid-related hospitalisation has increased alongside a simultaneous reduction in people accessing specialist addiction treatment. We aimed to determine the hospitalisation patterns of people presenting to addiction treatment with problematic use of alcohol or opioids, and estimate how individual sociodemographic characteristics and hospital admission diagnoses are associated with the rate of hospitalisation, death and successful completion of addiction treatment.

METHODS

A national record linkage between Hospital Episode Statistics (HES) and the National Drug Treatment Monitoring System (NDTMS) captured lifetime hospital admission profiles of people presenting to addiction services in England in 2018/19. Latent class analysis assigned individuals to clusters based on the ICD-10 diagnosis coded as primary reason for admission. Negative binomial, and multilevel logistic regression models determined if outcomes differed due to sociodemographic characteristics or assigned diagnostic clusters.

FINDINGS

Inpatient data were available for 64,840 alcohol patients, and 107,296 opioid patients. The most common reasons for admission were alcohol withdrawal (n = 20,024 (5.3% of alcohol-cohort admissions)), and unspecified illness (n = 11,387 (2.1% of opioid-cohort admissions)). Seven diagnostic clusters were identified for each substance cohort. People with admissions predominantly relating to mental and behavioural disorders, and injuries or poisonings had significantly higher hospitalisation rates (adjusted IRR 7.06 (95%CI 6.72-7.42);p < 0.001), higher odds of death during addiction treatment (adjusted OR 2.71 (95%CI 2.29-3.20);p < 0.001) and lower odds of successful treatment completion (adjusted OR 0.72 (95%CI 0.68-0.76);p < 0.001).

INTERPRETATION

This is the first study to interrogate national hospitalisation patterns within people presenting to addiction services with problematic use of alcohol or opioids. Having identified high-risk, high-cost individuals with increased hospital usage, and increased odds of death, future work should focus on targeting appropriate interventions, to improve their health outcomes and prevent unnecessary hospital readmission.

Considering the Potential Benefits of Over-the-Counter Naloxone

Since 1999, annual opioid-related overdose (ORO) mortality has increased more than six-fold. In response to this crisis, the US Department of Health and Human Services outlined a 5-point strategy to reduce ORO mortality which included the widespread distribution of naloxone, an opioid antagonist that can rapidly reverse an opioid overdose. Increased distribution has been facilitated by the implementation of naloxone access laws in each US state aimed at increasing community access to naloxone. While these laws differ from state-to-state, most contain mechanisms to enable pharmacists to dispense naloxone without a patient-specific prescription. These laws have enhanced community naloxone distribution, both from pharmacies and overdose education and naloxone distribution programs, and produced positive effects on ORO mortality. However, a growing body of evidence has revealed that significant barriers to naloxone access from pharmacies remain, and annual ORO deaths have continued to climb. Given these concerns, there has been a push among some clinicians and policymakers for the US Food and Drug Administration to re-classify naloxone as an over-the-counter (OTC) medication as a means to further increase its accessibility. If an OTC transition occurs, educational outreach and funding for clinical innovations will continue to be crucial given the important role of health professionals in recommending naloxone to people at risk for experiencing or witnessing an ORO. Recognizing the severity of the ORO public health crisis, we believe transitioning formulations of naloxone approved for layperson use to OTC status would result in a net benefit through increased access. However, such a change should be combined with measures to ensure affordability.

A scoping review of factors that influence opioid overdose prevention for justice-involved populations

BACKGROUND

There is a high risk of death from opioid overdose following release from prison. Efforts to develop and implement overdose prevention programs for justice-involved populations have increased in recent years. An understanding of the gaps in knowledge on prevention interventions is needed to accelerate development, implementation, and dissemination of effective strategies.

METHODS

A systematic search process identified 43 published papers addressing opioid overdose prevention in criminal justice settings or among justice-involved populations from 2010 to February 2020. Cross-cutting themes were identified, coded and qualitatively analyzed.

RESULTS

Papers were coded into five categories: acceptability (n = 8), accessibility (n = 4), effectiveness (n = 5), feasibility (n = 7), and participant overdose risk (n = 19). Common themes were: (1) Acceptability of naloxone is associated with injection drug use, overdose history, and perceived risk within the situational context; (2) Accessibility of naloxone is a function of the interface between corrections and community; (3) Evaluations of overdose prevention interventions are few, but generally show increases in knowledge or reductions in opioid overdose; (4) Coordinated efforts are needed to implement prevention interventions, address logistical challenges, and develop linkages between corrections and community providers; (5) Overdose is highest immediately following release from prison or jail, often preceded by service-system interactions, and associated with drug-use severity, injection use, and mental health disorders, as well as risks in the post-release environment.

CONCLUSION

Study findings can inform the development of overdose prevention interventions that target justice-involved individuals and policies to support their implementation across criminal justice and community-based service systems.

Preparing pharmacists to increase naloxone dispensing within community pharmacies under the Pennsylvania standing order

PURPOSE

Opioid misuse and overdose deaths remain a public health concern in the United States. Pennsylvania has one of the highest rates of opioid overdose deaths in the country, with Philadelphia County's being 3 times higher than the national average. Despite several multimodal interventions, including use of SBIRT (screening, brief intervention, and referral to treatment) methods and naloxone distribution, the rate of overdose deaths remains high.

METHODS

To gain insights on strategies for improving access to naloxone and naloxone distribution by pharmacists in Philadelphia County, a study was conducted in 11 community pharmacies (chain and independent) in Philadelphia. Twenty-four pharmacists were recruited and completed SBIRT and naloxone trainings. Each pharmacy elected to have at least 1 pharmacy champion who received additional training on and helped develop pharmacy site-specific naloxone dispensing protocols.

RESULTS

Pre-post survey results showed a reduction in stigmatizing attitudes regarding naloxone dispensing and an increase in pharmacists' understanding of the standing order and appropriate naloxone use. There was an increase in pharmacists' self-reported confidence in their ability to appropriately identify, discuss, and dispense naloxone to patients. All pharmacies increased their average monthly dispensing rate following protocol implementation.

CONCLUSION

Pharmacists who received both trainings were more likely to change naloxone dispensing practices, leading to an overall increase in naloxone dispensing by community pharmacists. The study addressed overall gaps in pharmacists' knowledge, reduced stigma, and prepared pharmacists to address opioid use and overdose prevention with their patients. The described pharmacist-led patient counseling and intervention service for overdose prevention may be explored as a model for other community pharmacies to adopt to improve naloxone dispensing and similar interventions to reduce overdose deaths.

Understanding overdose incidents in Canadian federal custody

BACKGROUND

While the community effects of the opioid-related drug crisis in Canada are well documented, limited detailed data is available on overdose trends among custodial populations. Given that this crisis has disproportionate impacts on justice involved persons, research is needed to understand the implications of this crisis within institutional settings.

METHODS

We examined all overdose incidents that occurred between the 2012/2013 and 2018/2019 fiscal years in a federal correctional institution in Canada. An incident report search was conducted to identify overdose related incidents during this period. Information about the incident and characteristics of the victim was collected from incident reports, investigations, and victim case files.

RESULTS

Over the period under examination, overdose incidents steadily increased (i.e., from 40 in 2012/2013, to 110 non-fatal incidents in 2018/2019), although there was considerable regional and institutional variation. The number of incidents involving opioids, particularly fentanyl, increased both in raw numbers and as a percentage of overall incidents (i.e., from 3% in 2012/2013 to 47% in 2017/2018, and 34% of non-fatal incidents in 2018/2019). Other substances continue to contribute to overdose incidents; in fact, non-opioid prescription medications (i.e., non-illicit medications such as anti-convulsant drugs and anti-depressants) remain the most common among intentional non-fatal incidents. Relative to the general in-custody population, victims of overdose incidents tended to be younger and were more likely to be serving a determinate sentence, be on a repeat federal sentence, and be serving time for robbery. Mental health conditions and histories of substance use were common.

CONCLUSION

The effects of the overdose crisis are pronounced within certain Canadian federal institutions, illustrated by a growing number of fentanyl-related incidents. Institutional variation and variation in incidents (e.g., substance and intentionality) highlight diversity in drug activities among this custodial population and the need for multi-faceted responses that are reflective of local situations.

Projected Estimates of Opioid Mortality After Community-Level Interventions

Importance

The United States is experiencing a crisis of opioid overdose. In response, the US Department of Health and Human Services has defined a goal to reduce overdose mortality by 40% by 2022.

Objective

To identify specific combinations of 3 interventions (initiating more people to medications for opioid use disorder [MOUD], increasing 6-month retention with MOUD, and increasing naloxone distribution) associated with at least a 40% reduction in opioid overdose in simulated populations.

Design, Setting, and Participants

This decision analytical model used a dynamic population-level state-transition model to project outcomes over a 2-year horizon. Each intervention scenario was compared with the counterfactual of no intervention in simulated urban and rural communities in Massachusetts. Simulation modeling was used to determine the associations of community-level interventions with opioid overdose rates. The 3 examined interventions were initiation of more people to MOUD, increasing individuals' retention with MOUD, and increasing distribution of naloxone. Data were analyzed from July to November 2020.

Main Outcomes and Measures

Reduction in overdose mortality, medication treatment capacity needs, and naloxone needs.

Results

No single intervention was associated with a 40% reduction in overdose mortality in the simulated communities. Reaching this goal required use of MOUD and naloxone. Achieving a 40% reduction required that 10% to 15% of the estimated OUD population not already receiving MOUD initiate MOUD every month, with 45% to 60%% retention for at least 6 months, and increased naloxone distribution. In all feasible settings and scenarios, attaining a 40% reduction in overdose mortality required that in every month, at least 10% of the population with OUD who were not currently receiving treatment initiate an MOUD.

Conclusions and Relevance

In this modeling study, only communities with increased capacity for treating with MOUD and increased MOUD retention experienced a 40% decrease in overdose mortality. These findings could provide a framework for developing community-level interventions to reduce opioid overdose death.

Commentary on Hill et al.: Breaking down barriers-increasing access to lifesaving opioid use disorder medications to save lives

Numerous barriers exist for patients attempting to access treatment for opioid-use disorder and/or naloxone, with geographical, racial, and age-related differences exacerbating these hardships.

Injecting Alone is More Common among Men, Frequent Injectors and Polysubstance Users in a Sample of People Who Inject Drugs

Injecting alone increases the risk of a fatal overdose. We examined the extent of such behavior in a sample of people who inject drugs (PWID) and the typical characteristics of those injecting alone at least once during the past four weeks. A cross-sectional study. PWID recruited from the street and from low-threshold services in seven Norwegian cities in September 2017 (n = 359). Associations between characteristics and injecting alone were examined using logistic regression analysis. The independent variables were gender (female/male), age, having received overdose-prevention education (no/yes), and, in the past four weeks; homelessness/shelter use (no/yes), in opioid substitution treatment (no/yes), injecting ≥ four days a week (no/yes), and substances injected (opioids only/opioids and other/other only/central stimulants (CS) only/CS and other/CS and opioids/CS, opioids and other). The adjusted odds ratios (aOR) and 95% Confidence Intervals (CI) were reported. Of the 359 PWID, 84.4% reported having injected alone. Males were more likely than females to inject alone (aOR = 1.88 95% CI 1.00-3.54). Furthermore, those injecting frequently (aOR = 1.99 95% CI 1.02-3.86) and those injecting multiple substances (CS, opioids and other) (aOR = 2.94 95% CI 1.01-8.58) were more likely to inject alone compared to those injecting less frequently and opioids only. Although not statistically significant, the effect sizes in the logistic regression models suggest that polysubstance use may be driven by CS use. Injecting alone was common in our sample of PWID, and male gender, frequent injecting and polysubstance injecting were associated with this behavior.

Stakeholders' Perceptions of Factors Influencing the Use of Take-Home-Naloxone

Background and Aims: Opioid associated death and overdose is a growing burden in societies all over the world. In recent years, legislative changes have increased access to naloxone in the take-home setting for use by patients with a substance use disorder and bystanders, to prevent opioid overdose deaths. However, few studies have explored the factors influencing the uptake by its multiple stakeholders. The aim of this scoping review was to explore the factors influencing the use of take-home naloxone from the perspectives of different stakeholders. Methods: A scoping review methodology was adopted with a systematic search of databases EMBASE, MEDLINE and PubMed. A variation of the search words “naloxone”, “opioid” and “overdose” were used in each database. The articles were screened according to the predetermined inclusion/exclusion criteria and categorized based on their key perspective or target population. Results: The initial database search yielded a total of 1483 articles. After a series of screening processes, 51 articles were included for analysis. Two key stakeholder perspectives emerged: patients and bystanders (n = 36), and healthcare professionals (n = 15). Within the patient and bystander group, a strong consensus arose that there were positive outcomes from increased access to take-home naloxone and relevant training programs. Despite these positive outcomes, some healthcare professionals were concerned that take-home naloxone would encourage high-risk opioid use. Conclusion: Take-home naloxone is slowly being introduced into community practice, with a sense of enthusiasm from patients and bystanders. There are still a number of barriers that need to be addressed from healthcare professionals’ perspective. Future research should be aimed at emergency care professionals outside of the US, who are most experienced with naloxone and its potential impact on the community.

The association of criminal justice supervision setting with overdose mortality: a longitudinal cohort study

BACKGROUND AND AIMS

Despite the high prevalence of substance use among people in the US criminal justice system, little is known about the incidence of overdose mortality by use patterns, drug convictions and supervision setting. We examined the associations between these characteristics and overdose mortality.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

Individuals sentenced to prison, jail, probation or jail plus probation for a felony conviction in Michigan, USA from 2003 to 2006.

MEASUREMENTS

Using the National Death Index, we assessed overdose mortality to December 2012. We calculated overdose mortality rates by pre-sentence opioid use, drug convictions and supervision setting. Multivariable analyses were conducted using competing risks regression with time-varying covariates.

FINDINGS

Among 140 266 individuals followed over a mean of 7.84 years [standard deviation (SD) = 1.52], 14.9% of the 1131 deaths were due to overdose (102.8 per 100 000 person-years). Over the follow-up, more than half of overdose deaths occurred in the community (57.7%), nearly a third (28.8%) on probation and 12.8% on parole. The adjusted risk of overdose death was lower on probation [hazard ratio (HR) = 0.71, 95% confidence interval (CI) = 0.60, 0.85] than in the community without probation or parole (HR = 1.00) but not significantly different on parole (HR = 1.13, 95% CI = 0.87, 1.47). Pre-sentence daily opioid use (HR = 3.54, 95% CI = 3.24, 3.87) was associated with an increased risk. Drug possession (HR = 1.11, 95% CI = 0.93, 1.31) and delivery convictions (HR = 0.92, 95% CI = 0.77, 1.09) were not significantly associated with overdose mortality.

CONCLUSIONS

Based on the absolute or relative risk, parole, probation and community settings are appropriate settings for enhanced overdose prevention interventions. Ensuring that individuals with pre-sentence opioid use have access to harm reduction and drug treatment services may help to prevent overdose among people involved with the criminal justice system.

The Opioid-overdose Reduction Continuum of Care Approach (ORCCA): Evidence-based practices in the HEALing Communities Study

BACKGROUND

The number of opioid-involved overdose deaths in the United States remains a national crisis. The HEALing Communities Study (HCS) will test whether Communities That HEAL (CTH), a community-engaged intervention, can decrease opioid-involved deaths in intervention communities (n = 33), relative to wait-list communities (n = 34), from four states. The CTH intervention seeks to facilitate widespread implementation of three evidence-based practices (EBPs) with the potential to reduce opioid-involved overdose fatalities: overdose education and naloxone distribution (OEND), effective delivery of medication for opioid use disorder (MOUD), and safer opioid analgesic prescribing. A key challenge was delineating an EBP implementation approach useful for all HCS communities.

METHODS

A workgroup composed of EBP experts from HCS research sites used literature reviews and expert consensus to: 1) compile strategies and associated resources for implementing EBPs primarily targeting individuals 18 and older; and 2) determine allowable community flexibility in EBP implementation. The workgroup developed the Opioid-overdose Reduction Continuum of Care Approach (ORCCA) to organize EBP strategies and resources to facilitate EBP implementation.

CONCLUSIONS

The ORCCA includes required and recommended EBP strategies, priority populations, and community settings. Each EBP has a "menu" of strategies from which communities can select and implement with a minimum of five strategies required: one for OEND, three for MOUD, and one for prescription opioid safety. Identification and engagement of high-risk populations in OEND and MOUD is an ORCCArequirement. To ensure CTH has community-wide impact, implementation of at least one EBP strategy is required in healthcare, behavioral health, and criminal justice settings, with communities identifying particular organizations to engage in HCS-facilitated EBP implementation.

Fatal accident inquiries into 83 deaths in Scottish prison custody: 2010-2013

BACKGROUND

The only non-legal reference in Lord Cullen's Review of fatal accident inquiry (FAI) Legislation in Scotland (2009) was my audit of FAIs into 97 deaths in prison custody in Scotland, 1999-2003: recommending that waiting time from prisoner death to end of FAI should be less than 1 year for 90% of FAIs, and epidemiological rules for FAIs to have a written determination versus formal findings.

AIMS

Audit of FAIs into 83 deaths in Scottish prison custody in the period 2010-2013.

METHOD

Assessement of waiting times from prisoner death to end of FAI; dissemination of written determinations; self-inflicted death rate per 1000 prisoner-years; cause of natural deaths; and yellow card submissions. Detailed cross-checking was nec37essary between Scottish Prison Service and courts' websites and the Scottish Fatalities Investigation Unit.

RESULTS

Of 83 FAIs into deaths in Scottish prison custody, 2010-2013, 37 (45%) were long-awaited (ongoing >2 years after the prisoner's death); 16 (19%, 95% CI 11-28%) beyond 3 years. Of 37 long-awaited FAIs, 27 made written determinations but only 12 of these (44%) were published. Self-inflicted deaths numbered 36: 1.1 per 1000 prisoner-years (95% CI 0.75-1.48). Of 47 deaths from natural causes, cardiovascular disease accounted for 23 (49%, 95% CI 34-63%); liver disease was implicated in 10 of 47. To support pharmacovigilance, submissions were made to Medicines and Healthcare Regulatory Agency for eight deaths (10%, 95% CI 4-19%).

CONCLUSIONS

FAIs into prisoner deaths in Scotland are too long-awaited given that four (5%) identified precautions that could have prevented death.

Economic Evaluation of Interventions to Address Opioid Misuse: A Systematic Review of Methods Used in Simulation Modeling Studies

OBJECTIVES

Several evidence-based interventions exist for people who misuse opioids, but there is limited guidance on optimal intervention selection. Economic evaluations using simulation modeling can guide the allocation of resources and help tackle the opioid crisis. This study reviews methods employed by economic evaluations using computer simulations to investigate the health and economic effects of interventions meant to address opioid misuse.

METHODS

We conducted a systematic mapping review of studies that used simulation modeling to support the economic evaluation of interventions targeting prevention, treatment, or management of opioid misuse or its direct consequences (ie, overdose). We searched 6 databases and extracted information on study population, interventions, costs, outcomes, and economic analysis and modeling approaches.

RESULTS

Eighteen studies met the inclusion criteria. All of the studies considered only one segment of the continuum of care. Of the studies, 13 evaluated medications for opioid use disorder, and 5 evaluated naloxone distribution programs to reduce overdose deaths. Most studies estimated incremental cost per quality-adjusted life-years and used health system and/or societal perspectives. Models were decision trees (n = 4), Markov (n = 10) or semi-Markov models (n = 3), and microsimulations (n = 1). All of the studies assessed parameter uncertainty though deterministic and/or probabilistic sensitivity analysis, 4 conducted formal calibration, only 2 assessed structural uncertainty, and only 1 conducted expected value of information analyses. Only 10 studies conducted validation.

CONCLUSIONS

Future economic evaluations should consider synergies between interventions and examine combinations of interventions to inform optimal policy response. They should also more consistently conduct model validation and assess the value of further research.

Naloxone Availability and Pharmacy Staff Knowledge of Standing Order for Naloxone in Pennsylvania Pharmacies

OBJECTIVE

To assess the availability and price of naloxone as well as pharmacy staff knowledge of the standing order for naloxone in Pennsylvania pharmacies.

METHODS

We conducted a telephone audit study from December 2016 to April 2017 in which staff from Pennsylvania pharmacies were surveyed to evaluate naloxone availability, staff understanding of the naloxone standing order, and out-of-pocket cost of naloxone.

RESULTS

Responses were obtained from 682 of 758 contacted pharmacies (90% response rate). Naloxone was stocked (ie, available for dispensing) in 306 (45%) pharmacies surveyed. Of the 376 (55%) pharmacies that did not stock naloxone, 118 (31%) stated that they could place an order for naloxone for pickup within 1 business day. Responses by pharmacy staff to questions about key components of the standing order for naloxone were collected from 581 of the 682 pharmacies who participated in the survey (85%). Of the 581 pharmacy staff members who stated that they either stocked or could order naloxone, 64% correctly answered all questions pertaining to understanding of the naloxone standing order. The respective median out-of-pocket prices stated in the audit varied by formulation and ranged from $50 to $4000. Staff from national pharmacies were significantly more likely than staff from regional/local chain and non-chain pharmacies to correctly answer that a prescription was not required to obtain naloxone (68.5%, 57.7%, and 52.4% respectively, (P = 0.0045).

CONCLUSIONS

Multiple barriers to naloxone access exist in pharmacies across a large, diverse state, despite the presence of a standing order to facilitate such access. Limited availability of naloxone in pharmacies, lack of knowledge or understanding by pharmacy staff of the standing order, and variability in out-of-pocket cost for this drug are among these potential barriers. Regulatory or legal incentives for pharmacies or drug manufacturers, education efforts directed toward pharmacy staff members, or other interventions may be needed to increase naloxone availability in pharmacies.

Assessing pharmacy-based naloxone access using an innovative purchase trial methodology

OBJECTIVES

Massachusetts was among the first states to allow standing orders to facilitate pharmacy-based naloxone purchases and reduce opioid overdose deaths. We conducted a unique purchase trial to establish a valid measure of standing order naloxone in Massachusetts, using purchasers from 2 high priority populations to determine whether naloxone is less accessible to those who use illicit opioids than other potential purchasers.

DESIGN

Purchase trial.

SETTING AND PARTICIPANTS

The study used a stratified random sample of 200 chain and independent retail pharmacies across Massachusetts. Each pharmacy underwent 2 purchase attempts-1 by a person who used illicit opioids (PWUIO) and 1 by a potential bystander who did not use illicit opioids but had a relationship with someone at risk of opioid overdose.

OUTCOME MEASURE

Successful or unsuccessful naloxone purchase attempt.

RESULTS

Overall, 322 of 397 purchase attempts (81%) were successful, with no statistically significant difference between PWUIO and bystanders (P = 0.221). Most purchases (93%) resulted in the acquisition of single-step nasal naloxone (Narcan; median cost $133.38). Forty percent of the purchases included state-mandated verbal counseling, and PWUIO were significantly less likely to receive counseling than bystanders (30% vs. 51%, P < 0.001). Common reasons for failed purchase were not stocking naloxone (47%), price > $150 (25%), and requiring a prescription (15%). Chain pharmacies were significantly more likely to sell naloxone than independent pharmacies (86% vs. 53%, P < 0.001).

CONCLUSION

We documented high levels of naloxone access for both PWUIO and bystanders, suggesting Massachusetts could serve as a model for states seeking to improve pharmacy-based naloxone access. Additional implementation efforts should focus on expanding availability at independent pharmacies and supporting pharmacies in proactively offering naloxone to PWUIO and other high-risk individuals.

Prevalence and disparities in opioid overdose response training among people who inject drugs, San Francisco: Naloxone training among injectors in San Francisco

BACKGROUND

Expanding naloxone training stands to reduce opioid-related overdose deaths. The current study assessed the prevalence of overdose response training and use of naloxone among people who inject drugs (PWID).

METHODS

Data were from a survey of PWID in San Francisco in 2018, recruited by respondent-driven sampling (RDS). Eligibility criteria were age over 18 years, injected non-prescribed drugs in the last year, San Francisco residence, and referral by another participant. Interviews collected demographic characteristics and injection-related behavior.

RESULTS

The sample (N=458) was majority male (67.5%) and over 45.5 years. Over three-fourths (76.0%) injected primarily opioids. Overall, 62.9% received overdose response training and 68.8% owned a naloxone kit. A majority (77.9%) had witnessed an overdose in the past year, of whom 55.8% used naloxone the last time they witnessed an overdose. Receiving overdose response training was significantly lower among persons of non-white race/ethnicity compared to whites (adjusted odds ratio [AOR] 0.43, 95% CI 0.27, 0.69) and higher among those who owned naloxone (AOR 6.29, 95% confidence interval [CI] 3.95, 10.02) and used syringe exchange programs (AOR 3.51, 95% CI 1.41, 8.79).

CONCLUSION

While the majority of PWID have had overdose response training, gaps and disparities persist in promotion of naloxone use.

The relationship between incarceration history and overdose in North America: A scoping review of the evidence

INTRODUCTION

Rates of opioid overdose (OD) have risen to unprecedented numbers and more than half of incarcerated individuals meet the criteria for substance use disorder, placing them at high risk. This review describes the relationship between incarceration history and OD.

METHODS

A scoping review was conducted and criteria for inclusion were: set in North America, published in English, and non-experimental study of formerly incarcerated individuals. Due to inconsistent definitions of opioid OD, we included all studies examining OD where opioids were mentioned.

RESULTS

The 18 included studies were all published in 2001 or later. Four associations between incarceration history and OD were identified: (1) six studies assessed incarceration history as a risk factor for OD and four found a significantly higher risk of OD among individuals with a history of incarceration compared to those without; (2) nine studies examined the rate of OD compared to the general population: eight found a significantly higher risk of fatal OD among those with a history of incarceration and three documented the highest risk of death immediately following release; (3) six studies found demographic, substance use and mental health, and incarceration-related risk factors for OD among formerly incarcerated individuals; and (4) four studies assessed the proportion of deaths due to OD and found a range from 5 % to 57 % among formerly incarcerated individuals.

DISCUSSION

Findings support the growing call for large-scale implementation of evidence-based OD prevention interventions in correctional settings and among justice-involved populations to reduce OD burden in this high-risk population.

The Global State of Harm Reduction in Prisons

Despite the fact that a large portion of the prison population is made up of people who use and inject drugs, harm reduction continues to be extremely limited in prison settings. This article begins with a review of drug-related incarceration, drug use in prisons, and HIV and hepatitis C (HCV) prevalence among prisoners globally. It presents the scientific evidence, alongside legal and economic arguments supporting the provision of harm reduction to people who use drugs, both inside and outside of prisons. The article then provides a global overview of the availability, accessibility, and quality of harm reduction services in prisons-specifically needle and syringe programs; opioid substitution therapy; provision of the opioid agonist naloxone; and diagnosis, treatment, and care for HIV, HCV, and tuberculosis.

Opioid use disorder research and the Council for the Advancement of Nursing Science priority areas

BACKGROUND

Chronic diseases, such as opioid use disorder (OUD) require a multifaceted scientific approach to address their evolving complexity. The Council for the Advancement of Nursing Science's (Council) four nursing science priority areas (precision health; global health, determinants of health, and big data/data analytics) were established to provide a framework to address current complex health problems.

PURPOSE

To examine OUD research through the nursing science priority areas and evaluate the appropriateness of the priority areas as a framework for research on complex health conditions.

METHOD

OUD was used as an exemplar to explore the relevance of the nursing science priorities for future research.

FINDINGS

Research in the four priority areas is advancing knowledge in OUD identification, prevention, and treatment. Intersection of OUD research population focus and methodological approach was identified among the priority areas.

DISCUSSION

The Council priorities provide a relevant framework for nurse scientists to address complex health problems like OUD.

Circumstances of overdose among street-involved, opioid-injecting women: Drug, set, and setting

INTRODUCTION

Current discourses about the causes of the overdose crisis largely focus on the harmful effects of drugs. Prior research, however, indicates that drug use experience is shaped by complex interactions of drugs with physiological and mental "sets" of people who use drugs and the wider social and physical "setting." Zinberg's "drug, set, and setting" theoretical framework was applied to identify patterns in circumstances leading up to women's overdose.

METHODS

In-depth semi-structured interviews were conducted with 29 opioid-injecting street-involved women, clients of a Philadelphia harm reduction program. Qualitative analysis with deductive and inductive coding was utilized to examine transcripts for theory-driven and emerging themes.

RESULTS

Ten out of 29 women attributed their overdose to "drugs," reporting the unpredictable quality of street opioids, concurrent use of benzodiazepines, or chasing the "high." Thirteen women reported "set" as a type of circumstance where their emotional states were affected by a "good" or "bad" day, leading them to unusual drug consumption practices. Six women described "setting" type of circumstances where their overdose was preceded by a recent change in context, such as release from prison, which prompted unsafe drug use to address physiological or psychological dependence on drugs.

CONCLUSION

While all overdoses result from the pharmacological action of drugs, some overdoses were triggered by circumstances occurring in women's set or setting. Overdose prevention policies should embrace not only individual-level behavioral interventions, but also structural measures to address stress, social isolation, and risky drug use contexts that plague the lives of street-involved women who inject opioids.

Estimating the impact of wide scale uptake of screening and medications for opioid use disorder in US prisons and jails

BACKGROUND

Medications for opioid use disorder (OUD) are the most effective treatment for OUD, but uptake of these life-saving medications has been extremely limited in US prisons and jail settings, and limited data are available to guide policy decisions. The objective of this study was to estimate the impact of screening and treatment with medications for OUD in US prisons and jails on post-release opioid-related mortality.

METHODS

We used data from the National Center for Vital Statistics, the Bureau of Justice Statistics, and relevant literature to construct Monte Carlo simulations of a counterfactual scenario in which wide scale uptake of screening and treatment with medications for OUD occurred in US prisons and jails in 2016.

RESULTS

Our model predicted that 1840 (95% Simulation Interval [SI]: -2757 - 4959) lives would have been saved nationally if all persons who were clinically indicated had received medications for OUD while incarcerated. The model also predicted that approximately 4400 (95% SI: 2675 - 5557) lives would have been saved nationally if all persons who were clinically indicated had received medications for OUD while incarcerated and were retained in treatment post-release. These estimates correspond to 668 (95% SI: -1008 - 1812) and 1609 (95% SI: 972 - 2037) lives saved per 10,000 persons incarcerated, respectively.

CONCLUSIONS

Prison and jail-based programs that comprehensively screen and provide treatment with medications for OUD have the potential to produce substantial reductions in opioid-related overdose deaths in a high-risk population; however, retention on treatment post-release is a key driver of population level impact.

Protocol for a multi-site study of the effects of overdose prevention education with naloxone distribution program in Skåne County, Sweden

BACKGROUND

Continuously high rates of overdose deaths in Sweden led to the decision by the Skåne County to initiate the first regional take-home naloxone program in Sweden. The project aims to study the effect of overdose prevention education and naloxone distribution on overdose mortality in Skåne County. Secondary outcome measures include non-fatal overdoses and overdose-related harm in the general population, as well as cohort-specific effects in study participants regarding overdoses, mortality and retention in naloxone program.

METHODS

Implementation of a multi-site train-the-trainer cascade model was launched in June 2018. Twenty four facilities, including opioid substitution treatment units, needle exchange programs and in-patient addiction units were included for the first line of start-up, aspiring to reach a majority of individuals at-risk within the first 6 months. Serving as self-sufficient naloxone hubs, these units provide training, naloxone distribution and study recruitment. During 3 years, questionnaires are obtained from initial training, follow up, every sixth month, and upon refill. Estimated sample size is 2000 subjects. Naloxone distribution rates are reported, by each unit, every 6 months. Medical diagnoses, toxicological raw data and data on mortality and cause of death will be collected from national and regional registers, both for included naloxone recipients and for the general population. Data on vital status and treatment needs will be collected from registers of emergency and prehospital care.

DISCUSSION

Despite a growing body of literature on naloxone distribution, studies on population effect on mortality are scarce. Most previous studies and reports have been uncontrolled, thus not being able to link naloxone distribution to survival, in relation to a comparison period. As Swedish registers present the opportunity to monitor individuals and entire populations over time, conditions for conducting systematic follow-ups in the Swedish population are good, serving the opportunity to study the impact of large scale overdose prevention education and naloxone distribution and thus fill the knowledge gap.

Harm reduction programs and policy in Australia: barriers and enablers to effective implementation

Abstract. Background: Harm reduction is an integral component of Australia’s overall national drug policy. Harm reduction policy and interventions can be applied to any legal or illegal drug to mitigate harm without necessarily reducing use, but harm reduction is traditionally conceptualised in relation to injecting drug use. Early and comprehensive adoption of many innovative harm reduction interventions has meant that Australia has had significant success in reducing a number of drug related harms, avoided disease epidemics experienced in other countries, and established programs and practices that are of international renown. However, these gains were not easily established, nor necessarily permanent. Aim: In this paper we explore the past and present harm reduction policy and practice contexts that normalised and facilitated harm reduction as a public health response, as well as those converse contexts currently creating opposition to additional or expanded interventions. Importantly, this paper discusses the intersection between various interventions, such as needle and syringe distribution and drug treatment programs. Finally, we detail some of the practical lessons that have been learned via the Australian experience, with the hope that these lessons will assist to inform and improve international harm reduction implementation.

Endogenous opiates and behavior: 2017

This paper is the fortieth consecutive installment of the annual anthological review of research concerning the endogenous opioid system, summarizing articles published during 2017 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides and receptors as well as effects of opioid/opiate agonists and antagonists. The review is subdivided into the following specific topics: molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors (1), the roles of these opioid peptides and receptors in pain and analgesia in animals (2) and humans (3), opioid-sensitive and opioid-insensitive effects of nonopioid analgesics (4), opioid peptide and receptor involvement in tolerance and dependence (5), stress and social status (6), learning and memory (7), eating and drinking (8), drug abuse and alcohol (9), sexual activity and hormones, pregnancy, development and endocrinology (10), mental illness and mood (11), seizures and neurologic disorders (12), electrical-related activity and neurophysiology (13), general activity and locomotion (14), gastrointestinal, renal and hepatic functions (15), cardiovascular responses (16), respiration and thermoregulation (17), and immunological responses (18).

Optimising opioid substitution therapy in the prison environment

PURPOSE

The purpose of this paper is to examine the current provision of opioid substitution therapy (OST) during and immediately following release from detention in prisons in England and Wales.

DESIGN/METHODOLOGY/APPROACH

A group of experts was convened to comment on current practices and to make recommendations for improving OST management in prison. Current practices were previously assessed using an online survey and a focus group with experience of OST in prison (Webster, 2017).

FINDINGS

Disruption to the management of addiction and reduced treatment choice for OST adversely influences adequate provision of OST in prison. A key concern was the routine diversion of opiate substitutes to other prisoners. The new controlled drug formulations were considered a positive development to ensure streamlined and efficient OST administration. The following patient populations were identified as having concerns beyond their opioid use, and therefore require additional considerations in prison: older people with comorbidities and complex treatment needs; women who have experienced trauma and have childcare issues; and those with existing mental health needs requiring effective understanding and treatment in prison.

ORIGINALITY/VALUE

Integration of clinical and psychosocial services would enable a joint care plan to be tailored for each individual with opioid dependence and include options for detoxification or maintenance treatment. This would better enable those struggling with opioid use to make informed choices concerning their care during incarceration and for the period immediately following their release. Improvements in coordination of OST would facilitate inclusion of strategies to further streamline this process for the benefit of prisoners and prison staff.

Opioid-related treatment, interventions, and outcomes among incarcerated persons: A systematic review

BACKGROUND

Worldwide opioid-related overdose has become a major public health crisis. People with opioid use disorder (OUD) are overrepresented in the criminal justice system and at higher risk for opioid-related mortality. However, correctional facilities frequently adopt an abstinence-only approach, seldom offering the gold standard opioid agonist treatment (OAT) to incarcerated persons with OUD. In an attempt to inform adequate management of OUD among incarcerated persons, we conducted a systematic review of opioid-related interventions delivered before, during, and after incarceration.

METHODS AND FINDINGS

We systematically reviewed 8 electronic databases for original, peer-reviewed literature published between January 2008 and October 2019. Our review included studies conducted among adult participants with OUD who were incarcerated or recently released into the community (≤90 days post-incarceration). The search identified 2,356 articles, 46 of which met the inclusion criteria based on assessments by 2 independent reviewers. Thirty studies were conducted in North America, 9 in Europe, and 7 in Asia/Oceania. The systematic review included 22 randomized control trials (RCTs), 3 non-randomized clinical trials, and 21 observational studies. Eight observational studies utilized administrative data and included large sample sizes (median of 10,419 [range 2273-131,472] participants), and 13 observational studies utilized primary data, with a median of 140 (range 27-960) participants. RCTs and non-randomized clinical trials included a median of 198 (range 15-1,557) and 44 (range 27-382) participants, respectively. Twelve studies included only men, 1 study included only women, and in the remaining 33 studies, the percentage of women was below 30%. The majority of study participants were middle-aged adults (36-55 years). Participants treated at a correctional facility with methadone maintenance treatment (MMT) or buprenorphine (BPN)/naloxone (NLX) had lower rates of illicit opioid use, had higher adherence to OUD treatment, were less likely to be re-incarcerated, and were more likely to be working 1 year post-incarceration. Participants who received MMT or BPN/NLX while incarcerated had fewer nonfatal overdoses and lower mortality. The main limitation of our systematic review is the high heterogeneity of studies (different designs, settings, populations, treatments, and outcomes), precluding a meta-analysis. Other study limitations include the insufficient data about incarcerated women with OUD, and the lack of information about incarcerated populations with OUD who are not included in published research.

CONCLUSIONS

In this carefully conducted systematic review, we found that correctional facilities should scale up OAT among incarcerated persons with OUD. The strategy is likely to decrease opioid-related overdose and mortality, reduce opioid use and other risky behaviors during and after incarceration, and improve retention in addiction treatment after prison release. Immediate OAT after prison release and additional preventive strategies such as the distribution of NLX kits to at-risk individuals upon release greatly decrease the occurrence of opioid-related overdose and mortality. In an effort to mitigate the impact of the opioid-related overdose crisis, it is crucial to scale up OAT and opioid-related overdose prevention strategies (e.g., NLX) within a continuum of treatment before, during, and after incarceration.

Impact of the take ACTION Train-the-Trainer model of opioid overdose education with naloxone distribution- who benefits?

BACKGROUND

Overdose education with naloxone distribution (OEND) is a key national strategy to reduce morbidity and mortality related to opioid overdoses. Train-the-trainer model has been one method to increase the pool of trainers to facilitate greater dissemination of OEND. This exploratory study seeks to (1) evaluate participant's change in knowledge and confidence, (2) examine if pre- and post-training test outcomes differed by occupation and level of experience, and (3) determine if train-the-trainer participants trained others 6 months later. Methods: Fifteen train-the-trainer sessions were delivered to staff from community organizations who served high-risk clients in four counties whose overdose death rates ranged from 11.2 to 32.8 per 100,000. Participants were administered pre- and post-training tests from September 2017 to December 2018. A follow-up survey was conducted 6 months post-training to evaluate outcomes. Final paired pre-and post-training surveys of 109 participants were used for analysis. Paired sample t-tests were used to evaluate changes in the knowledge and confidence in teaching others. One-way ANOVA compared the change scores across groups with different demographic or experiential characteristics. Kruskal-Wallis Test was used for Likert scales. Results: The one and one-half hour train-the-trainer curriculum increased participants' knowledge and confidence to teach others (p < .001). This was particularly true for participants who had no prior experience compared to those who had some experience with naloxone (p = .0003). Changes in confidence to teach others significantly improved among demographic subgroups of participants. At 6 months after completing the train-the-trainer curriculum, 14 participants had trained 243 new trainees. Conclusions: Implementing a train-the-trainer model for OEND increases knowledge and participants' confidence to teach others. This demonstrates the important potential of the train-the-trainer model to respond to the growing opioid overdose epidemic.

Patient characteristics associated with being offered take home naloxone in a busy, urban emergency department: a retrospective chart review

BACKGROUND

Overdose deaths can be prevented by distributing take home naloxone (THN) kits. The emergency department (ED) is an opportune setting for overdose prevention, as people who use opioids frequently present for emergency care, and those who have overdosed are at high risk for future overdose death. We evaluated the implementation of an ED-based THN program by measuring the extent to which THN was offered to patients presenting with opioid overdose. We analyzed whether some patients were less likely to be offered THN than others, to identify areas for program improvement.

METHODS

We retrospectively reviewed medical records from all ED visits between April 2016 and May 2017 with a primary diagnosis of opioid overdose at a large, urban tertiary hospital located in Alberta, Canada. A wide array of patient data was collected, including demographics, opioid intoxicants, prescription history, overdose severity, and whether a naloxone kit was offered and accepted. Multivariable analyses were used to identify patient characteristics and situational variables associated with being offered THN.

RESULTS

Among the 342 ED visits for opioid overdose, THN was offered in 49% (n = 168) of cases. Patients were more likely to be offered THN if they had been found unconscious (Adjusted Odds Ratio 3.70; 95% Confidence Interval [1.63, 8.37]), or if they had smoked or injected an illegal opioid (AOR 6.05 [2.15,17.0] and AOR 3.78 [1.32,10.9], respectively). In contrast, patients were less likely to be offered THN if they had a current prescription for opioids (AOR 0.41 [0.19, 0.88]), if they were admitted to the hospital (AOR 0.46 [0.22,0.97], or if they unexpectedly left the ED without treatment or before completing treatment (AOR 0.16 [0.22, 0.97).

CONCLUSIONS

In this real-world evaluation of an ED-based THN program, we observed that only half of patients with opioid overdose were offered THN. ED staff readily identify patients who use illegal opioids or experience a severe overdose as potentially benefitting from THN, but may miss others at high risk for future overdose. We recommend that hospital EDs provide additional guidance to staff to ensure that all eligible patients at risk of overdose have access to THN.
