Social and structural contexts of injectable opioid agonist treatment : a critical ethnographic study of people's experiences in Vancouver, BC
Bibliographic record
Abstract
Background: As part of the response to Canada’s worsening overdose crisis driven by a toxic adulterated drug supply, there has been increased attention to and expansion of drug treatment options, including injectable opioid agonist treatment (iOAT). Many people who access iOAT experience significant social inequities (insecure housing, poverty) and are impacted by multiple and intersecting forms of discrimination (racism, sexism). As this treatment has only recently expanded, there is a gap in research on how iOAT can help alleviate and account for these social inequities in the context of the ongoing adulteration of the illicit drug supply. This dissertation addresses this gap by examining how social and structural factors impact people’s engagement with iOAT to optimize program delivery. Methods: This dissertation draws on critical ethnographic and community-based approaches conducted with people accessing four iOAT programs in Vancouver’s Downtown Eastside neighbourhood from May 2018 to November 2019. Data included in-depth baseline and follow-up interviews and approximately 50 hours of observation fieldwork conducted in one iOAT program and with a subsample of participants in the surrounding neighbourhood. Analysis leveraged a structural vulnerability lens and complementing critical social science theories to characterize the social-structural dynamics that shape people’s engagement with iOAT. Results: This dissertation characterizes why people engage with iOAT and how they navigate its enabling and constraining aspects. Participants accessed iOAT for resources to address social inequities and physical harms (withdrawal, chronic pain, overdose) experienced in the context of the ongoing toxic drug supply. While iOAT provides access to life-saving medication and health and social supports, program operations (e.g., surveillance) can create barriers to engagement. Findings highlight how intersecting structural vulnerabilities, including gendered power dynamics, housing insecurity, poverty, inadequate chronic pain management, and drug use-related stigma, mediate how people engage with iOAT. Conclusion: Drawing attention to structural vulnerability, study findings highlight the diverse and pragmatic ways people engage with iOAT to achieve personal goals and manage their opioid use in a broader socio-political context and worsening overdose crisis. Findings point to the importance and modification of integrating low-threshold, equity-oriented, and patient-centred approaches to iOAT care to meet people’s diverse needs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
