Abstract

Introduction

The current overdose crisis is a critical public health issue worldwide. In 2015, approximately 450,000 people died as a result of drug use, with one-third to one-half due to overdose deaths, most of which were attributable to opioids.1 In the European Union, there were 8200 deaths caused by illicit drug use in 2017, and 90% of these were from opioids.2 In Canada, more than 11 people have died due to opioid overdoses each day since 2015, while many more individuals are hospitalized or seek care at emergency departments for opioid poisioning.3,4 The United States has the highest rate of overdose deaths, with more than 130 people dying each day from overdoses involving opioids.5,6 There is an urgent need to identify strategies that address the root causes of the overdose crisis, which include structural barriers to care, mental health and addictions, poverty, stigma, and their intersections.7-10 There is also a need to move beyond understanding cause and effect to addressing possible interventions for the overdose crisis. Identifying such approaches will require a consideration of frameworks beyond those of the health care sector.11 Despite being recognized in North America as a public health crisis spanning multiple sectors, there is a lack of multidisciplinary knowledge syntheses on the overdose crisis.

It is important to take a broad perspective on different types of legal approaches and government policies that may impact the overdose crisis. Changes to existing legal approaches and government policies related to illegal substances and drug use show that innovations may have far-reaching effects.12 Laws can affect which substances are most readily available to people and the relative purity of illegal substances.12,13 Consequently, new legal approaches may have a substantial impact if they shift use to a safer drug supply; for example, the use of prescription hydromorphone rather than procurement of illegal opioids with a high chance of contamination by fentanyl can significantly mitigate potential harms. Such legal measures can include decriminalization of drug possession or legalization of “hard” drugs (eg, heroin or cocaine).

Other legal approaches and government policies that do not directly target the overdose crisis may unintentionally affect overdose risk and other harms related to substance use. For example, some studies suggest that the legalization of recreational cannabis is associated with a reduction in opioid overdose rates.15 Additional legal options include enacting a Good Samaritan law that grants prosecutorial immunity for simple possession to people who seek help during a drug overdose; introducing therapeutic court programs (also known as specialty courts, drug courts, or dissuasion commissions) where drug possession is handled in the legal system through referral to addiction treatment programs; implementing involuntary confinement in medical care for individuals with substance use disorders; and pursuing murder prosecutions for drug dealers in cases of overdose deaths.16

It is also critical to consider the unintended, and sometimes adverse, consequences of policies enacted to address public health and safety. For instance, laws that restrict substance use may place barriers on individuals who need care but are reluctant to seek it due to fear of prosecution, stigma, or other negative consequences.12 Prescription drug monitoring programs may lead to inadvertent harms, as individuals who no longer have access to prescription opioids may seek illicit and contaminated substances.17

To address this topic, we gathered a team of researchers and decision-makers with expertise spanning the policy, health care, law enforcement, and legal systems to determine the most important review question to be answered using knowledge synthesis. We used an integrated knowledge translation approach. Each of the team members identified topics most relevant to them, which were then compiled into a list. The list was reviewed by the team, and each potential topic was discussed, merged, or refined, by consensus. Team members then anonymously voted for their priority topic, and the review question that received the most votes was chosen. Thus, we will undertake a scoping review on the different legal approaches and government policies that address the overdose epidemic. For the purpose of the protocol and review, the term “legal approaches and government policies” will be used to describe the variety of approaches that have been taken internationally through judiciary mechanisms as well as government measures, including legislative options and changes to health and social policy.

In the current crisis, evidence suggests that contamination of the illegal drug supply by high-potency opioid analogues, such as fentanyl, has been a main contributor to high overdose and death rates.14 Given the critical role of opioids within the current overdose crisis, a decision was made to limit the scope of this review to studies where the legal approach or government policy directly addressed opioids (both prescription or illegally obtained/manufactured) or where the consequences of the legal approach or government policy could directly or indirectly be associated with opioid use–related harms or outcomes. Limiting the scope to opioids will also make the review more manageable to conduct.

As the literature for legal approaches and government policies is heterogeneous and dispersed throughout the health, legal, and social sciences literature, we determined that a scoping review is the appropriate approach to answer our review questions. A preliminary search of MEDLINE, Open Science Framework (OSF), the Cochrane Database of Systematic Reviews, the Campbell Collaboration, PROSPERO, and Google Scholar found no existing knowledge syntheses on this topic.

This scoping review will serve as a comprehensive source of information for policy-makers and individuals working at the forefront of the overdose crisis to identify legal approaches and government policies already in place or those that have been recently implemented worldwide. It may also be used to inform the development of evidence-based legal approaches and government policies that can be implemented to mitigate the effects of the ongoing overdose crisis.

Review questions

  • i. What literature exists on the different legal approaches and government policies that have been implemented internationally resulting in an intended or unintended effect on the current overdose epidemic?
  • ii. What literature exists that documents the beneficial, harmful, and unintended effects of different legal approaches and government policies on opioid use–related harms and mortality?

Inclusion criteria

Concept

The scope of this review encompasses legal or policy approaches at a governmental or regulatory level that relate directly or indirectly to opioids, and intentionally or unintentionally affect an opioid use–related harm. A legal approach or government policy is an action taken at the international (ie, United Nations), federal, state/province, or municipal levels. This can include actions that are legislative (eg, prescription drug monitoring programs) or regulatory (eg, changing the scheduling of a prescription drug). It also includes actions taken by other regulatory bodies (eg, health authorities, other agencies that govern the conduct of health professionals). A legal or policy approach can have intended effects (eg, reducing opioid prescribing rates) or unintended effects (eg, increasing illicit drug overdose rates). An opioid use–related harm is a negative result of opioid use and may include diverse outcomes including overdose, death, crime, or infectious diseases spread through injection drug use.

Context

The context for this review is global, and will include legal approaches and government policies from countries of any income levels.

Types of sources

This review will consider any research article or policy document. We will include empirical, quantitative, or qualitative studies, as well as other research that aims to i) compare legal approaches and government policies in different jurisdictions; ii) analyze codes, rules, acts, laws, or guidelines; or iii) present the consequences of implementation of policies or laws, or effects on society. Studies published in English from 2000 onward will be included. The publication date limit was imposed to attempt to capture studies that focus on a time period with comparable contextual factors to the present (ie, increased rates of opioid prescriptions, fentanyl contamination of illicit drugs).3,14 Commentaries and letters to the editor will be excluded, as they are not considered studies as defined above. Conference abstracts will be excluded, as they are often ongoing studies without finalized data; however, excluded conference abstracts will be used to search for full study reports that have not already been included.

Methods

This review will follow the JBI methodology for scoping reviews.18

Search strategy

An initial limited search of MEDLINE (Ovid) and Academic Search Complete (EBSCO) was undertaken to identify articles that met the inclusion criteria, along with papers that were identified by the review team as relevant. The titles and abstracts of these studies, along with articles already identified by the research team, were used to identify keywords and the indexing terms in each database. The keywords and index terms were used to create a search strategy that will be translated to all databases. A simplified version of the search was developed for legal databases. A full MEDLINE search is presented in Appendix I. The final step in the search strategy is to review the reference lists of all included studies, as well as to use Google Scholar to review citing papers to locate additional studies.

Information sources

We will search health sciences databases (MEDLINE [Ovid], Embase [Ovid], PsycINFO [EBSCO], CINAHL Complete [EBSCO], Native Health Database), legal databases (Legal Periodicals & Books [EBSCO], LegalTrac [GALE], HeinOnline), and social sciences databases (PAIS Index [ProQuest], Sociology Collection [ProQuest], Academic Search Complete [EBSCO], JSTOR Collection, and Project Muse) to ensure comprehensive identification of studies across disciplines. To reduce publication bias, we will conduct an extensive gray literature search to find non-commercially published literature. We will also search conference proceedings (PapersFirst [WorldCat], Web of Science Conference Proceedings Citation Index: Science, and Conference Proceedings Citation Index: Social Science & Humanities), government and non-governmental organizations reports (De Libris, EU Bookshop, EUR-Lex, WHO Library Database, National Information Center on Health Services Research, United Nations Offices on Drugs and Crime Website, RAND Corporation Website), gray literature databases (OpenGrey, Grey Literature Report), and other databases and search engines (DoPHER, Google).

Study selection

All identified studies will be uploaded into EndNote V9.1 (Clarivate Analytics, PA, USA) and duplicates will be removed. The references will then be uploaded to Rayyan (Qatar Computing Research Institute, Doha, Qatar) and any further identified duplicates will be removed. Due to the high number of expected results from our search, the titles and abstracts will first be screened by a single team member who will remove any that clearly do not include a legal approach, are not related to opioid use, or are clearly the wrong format (eg, commentary). When there is ambiguity, the team member will always choose to include studies for the next phase. The resulting titles and abstracts will be screened again independently and in duplicate by two team members using Rayyan. First, a pilot with 100 title and abstracts will be completed to test the inclusion criteria. The resulting full-text articles will then be reviewed independently and in duplicate by two team members using Rayyan. Again, a pilot with 50 full-text articles will be completed, and if this reveals a lack of consensus, the team members will meet to better clarify the inclusion criteria. Pilots of 50 articles will continue until at least 80% consensus has been reached. Any disagreements in screening and full-text review about the relevance of a particular study will be resolved through discussion until consensus is reached. When consensus cannot be reached, it will be reached through involvement of a third reviewer. The number of potential studies identified, number of abstracts reviewed, and number of full-text articles reviewed, as well as the number eliminated at each stage of the study selection process, will be documented. The results of the search and the study selection process will be reported narratively and using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR).19

Data extraction

A data extraction form will be created using REDCap (Vanderbilt University, TN, USA) electronic data capture tool. A draft of the fields for the data extraction form is included in Appendix II. Minimum data to be extracted from all sources include publication year, target substance, country, study population, conflicts of interest, type of legal approach/government policy, specific legal approach/government policy, and intended or unintended effects on the overdose epidemic or on opioid-related harms. Ten articles will be used in pilots to test the data extraction form. Once the data extraction form has been finalized, one team member will independently extract data from each article, and a second team member will independently verify the data extraction. Any disagreements will be discussed and resolved through consensus.

Data presentation

The results of the review will be presented as a narrative synthesis and in a tabular or diagrammatic form, depending on which is more appropriate to the objective of this review. Non-empirical sources will be presented in tabular form and will be mapped to the type of legal approach presented and country or region from where it is based. Empirical studies will be mapped to the type of legal approach, the specific legal approach, country/region, and outcomes, and will be presented in a table.
