Abstract

fetched live from OpenAlex

The study examined the impact of the COVID-19 pandemic on treatment access among individuals (n=225) presenting with problematic opioid use to the Rapid Access Addiction Medicine (RAAM) clinic at The Royal in Ottawa, Ontario.The COVID-19 pandemic led to government-imposed restrictions and service limitations.The RAAM clinic underwent two primary changes: (1) delivering services virtually rather than in-person appointments and (2) shifting from walk-in services to appointment-based services.The study was a retrospective chart review and data were extracted from an electronic health record, Meditech.Participants were patients who had an initial presentation to the RAAM clinic between March 16 th , 2019, and March 15 th , 2021, and had used opioids within the 30 days prior to their visit.Results indicated that RAAM changes decreased some groups' access to care such that fewer patients experiencing precarious housing and mental health comorbidities presented to the RAAM clinic after the onset of the pandemic.

Not 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.
