The Alberta Atlas of Healthcare Variation (A-Atlas): A New Clinical Tool
Bibliographic record
Abstract
Newly occurring and worsening pressure injuries are a challenge across LTC facilities in Alberta. Despite multiple risk reduction/prevention strategies and early identification and treatment approaches, there is inconsistency with how best practices are utilized across sites. The newly created Alberta Atlas of Healthcare Variation (A-Atlas) reveals the degree of variation by showing weighted median pressure injury rates across provincial zones, adjusted pressure injury rates over time, weighted median pressure injury rates between facilities grouped into different bed capacity ranges and crude pressure injury rates between first and subsequent assessments across sites. The goal of the A-Atlas is to raise awareness of clinical variation and prompt further investigation about why variation is present and whether the variation is warranted or unwarranted. It offers a data driven analysis to enable continuous quality improvement and stimulate action to improve patient outcomes.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
