Epidemiology of Community‐Acquired Pneumonia in Edmonton, Alberta: An Emergency Department‐Based Study
Bibliographic record
Abstract
Patients aged 17 years and older who presented to seven emergency departments in Edmonton, Alberta over a two-year period with community-acquired pneumonia (n=8144) were studied. The admission rates were 271/100,00 and 296/100,000 persons for year 1 and year 2 of the study, respectively. The admission rate increased with increasing age, peaking at 4639/100,000/year for those 90 years of age and older. In contrast, the percentage of patients who were admitted to an intensive care unit was highest for those in the younger age groups between 17 and 59 years of age. From 59 years of age and older, there was a progressive decline in the percentage of patients admitted to an intensive care unit, with approximately 1% of those in the 90 years and older age group admitted. A pronounced seasonal effect on the number of patients presenting to emergency department was also noted. During the winter months, there was up to a 50% increase in the number of cases compared with the summer months.

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.
