Sex Differences in Health Service Use for Mental and Substance Use Disorders Among Methamphetamine Users
Bibliographic record
Abstract
Methamphetamine and associated health service use are rising globally, with psychiatric complications that may impact women and men differently. However, there are no recent population-level estimates of mental health and addictions (MHA) service use among methamphetamine users. This thesis explores the relationship between methamphetamine use and MHA service use across Ontario from 2017 to 2019 by identifying methamphetamine users through drug screen results and identifies differences in psychiatric health service use between women and men who use methamphetamine. Service use was higher in people with a positive test compared to those with a negative test, sex affected the relationship between methamphetamine use and MHA service use differently across psychiatric diagnostic categories, and men were at higher risk of MHA ED visits and hospitalizations compared to women. Sex did not affect the risk of outpatient visits or length of hospitalization. These findings can guide health system planning and harm reduction efforts.

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.
