Implementation research to evaluate an educational intervention for people who inject drugs
Bibliographic record
Abstract
Abstract Objective In the context of disseminating harm reduction (HR) programmes in Europe, the Eurosider project aims to study the transferability of an effective educational intervention for people who inject drugs (PWID) to four European countries (Bulgaria, Greece, Portugal and Romania). This intervention, entitled Individually-Tailored Support and Education for Safer Injection (ITSESI), has been shown to reduce HIV-Hepatitis C Virus (HCV) risk practices by offering educational supervision during all phases of the injection sequence, from pre- to post-injection. Methods The project employs mixed methods and implementation science. The exploratory first step used qualitative interviews and other available data in each country. The second step consists in implementing and evaluating the intervention using a 6-month study conducted among 300 PWID enrolled in the 4 countries. They are interviewed at baseline and at 6 months. The third step will consist in designing, promoting and disseminating all the tools necessary to transfer ITSESI at the European level. Results Results from the exploratory phase highlighted two main determining factors for the feasibility of implementing ITSESI: funding and a repressive legal context. Preliminary results from a quantitative analysis of data from the second step will provide a baseline description of the 300 PWID. Discussion Findings to date indicate that an exploratory phase is crucial to adapt and transfer the intervention to local contexts and to evaluate it. More globally, the Eurosider project will 1) help understand each local context to adapt the intervention accordingly; 2) assess the feasibility and effectiveness of ITSESI in different contexts; 3) promote and disseminate tools and training to implement the intervention at the European level. Key messages People who inject drugs in European countries report HIV-HCV risk practices and adequate prevention should be provided. The implementation of an innovative educational intervention for people who inject drugs may be one response but requires to take into account contextual factors: funding and repressive drug policy.

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.
