Abstract
<h3>Introduction</h3> Canadian Paramedic services modified infection prevention and control (IPAC) practices in response to COVID-19. These changes may affect risk of exposure to infectious disease agents and can be used to inform future IPAC practices. We characterized COVID-19-related IPAC changes in the provinces of Alberta, British Columbia, Manitoba, Ontario, and Saskatchewan. <h3>Materials & Methods</h3> Questionnaire data (January 2021-Feb 2022) from the national COVID-19 Occupational Risks, Seroprevalence and Immunity among Paramedics (CORSIP) project was used to identify which IPAC practices were in place prior to COVID-19, and which were modified in response to COVID-19, including the timing of changes (March-May 2020; June-Aug 2020; Sept-Nov 2020; Nov 2020-present). <h3>Results</h3> 2939 participants were included (146, 1249, 139, 1317, 88 from Alberta, BC, Manitoba, Ontario, and Saskatchewan, respectively), of whom 2674 (91%) reported receiving IPAC training. IPAC measures that were common prior to COVID-19 included: personal protective equipment (PPE) training, patient screening, hand hygiene, N95/P100 respirators, gowns, impermeable suits, and cleaning/disinfection. COVID-related IPAC changes included: screening staff, social distancing, restricting aerosol generating procedures, masking patients, cloth face coverings, surgical masks, face shields, and elastomeric respirators. Changes were reported for all IPAC measures. Most (71%) of these changes were made early in the COVID-19 pandemic (March-May 2020). Differences in proportions across provinces, community practice settings, and professional regulation status were reported (p < .05) for hand hygiene, PPE training, screening of patients, face shields, and various respirator types. <h3>Conclusion</h3> Canadian paramedic services were quick to modify available IPAC measures. However, these changes were variable across provinces, regulation status, and setting for specific IPAC measures. Inconsistent IPAC measures across jurisdictions may contribute to variable risk of infectious disease exposure. An evidence-informed and nationally coordinated approach may provide more equitable exposure risk mitigation for paramedic workers.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
