Interventions for stimulant use in people who are homeless or vulnerably housed: a scoping review of the evidence including trauma-informed approaches.
Background: Stimulant use has been increasing globally over the past decade. People using drugs are now most often using both opioids and stimulants. In Canada, stimulants were involved in 68% of overdose deaths from 2020 to 2024. The overdose crisis has disproportionately impacted people experiencing homelessness. People experiencing homelessness are more likely to experience an overdose and stimulants are more likely to contribute directly to an overdose death in this population. Despite the growing need, a comprehensive and effective treatment program for people experiencing homelessness who use stimulants, that also considers trauma and safe supply options, is non-existent. We conducted a scoping review to identify the types of evidence-based treatments available to address stimulant use in people experiencing homelessness; whether any of these services were trauma-informed; and to identify knowledge gaps.
Methods: Using a peer-reviewed search strategy, we conducted searches in MEDLINE, Embase, PsychInfo via OVID, CINAHL, Global Health via EBSCOhost, and Scopus. Grey literature sources were hand searched. We included any primary research study with no restrictions on language or date. Reporting follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist.
Results: After de-duplication, 2914 titles and abstracts were screened, and 51 papers were moved to full text screening. Of this, 31 studies met eligibility criteria and were included for data extraction. Papers examined contingency management interventions (n = 20), residential treatment programs (n = 5), safer supply (n = 1), and other types of interventions (n = 4). Of the 31 papers, no studies reported using trauma-informed care approaches, although, seven incorporated some components of trauma-informed care. There was mixed evidence of effectiveness among studies, with rewards-based contingency management being generally effective and acceptable to participants.
Discussion: There is limited evidence available regarding stimulant use treatments for people experiencing homelessness, with most studies focusing on contingency management. Studies largely do not consider the effects of trauma in their intervention or study design. Further research is needed on harm reduction interventions such as stimulant safer supply or supervised consumption services, as well as outcomes other than abstinence that may be important to this population.
期刊介绍:
Harm Reduction Journal is an Open Access, peer-reviewed, online journal whose focus is on the prevalent patterns of psychoactive drug use, the public policies meant to control them, and the search for effective methods of reducing the adverse medical, public health, and social consequences associated with both drugs and drug policies. We define "harm reduction" as "policies and programs which aim to reduce the health, social, and economic costs of legal and illegal psychoactive drug use without necessarily reducing drug consumption". We are especially interested in studies of the evolving patterns of drug use around the world, their implications for the spread of HIV/AIDS and other blood-borne pathogens.
