Epidemiology of Nosocomial Pneumonia in Adults Hospitalized in Canadian Acute Care Facilities
Bibliographic record
Abstract
Background: Nosocomial pneumonia (NP) is a significant cause of morbidity and mortality in hospitalized patients.\nObjective: The objectives of this study were to describe the epidemiology of NP in adult patients hospitalized in Canadian acute care facilities and identify prognostic indicators for death.\nMethods: A retrospective cohort study was conducted in 114 patients with NP admitted to\nhospitals that participated in a 2002 Canadian point prevalence survey.\nResults: A high proportion of NP patients had a rapidly or ultimately fatal underlying illness. NP in non-intensive care unit (ICU) patients accounted for the larger proportion of these infections.There was no mortality difference between patients with and without ventilator-associated NP, or with and without ICU-acquired NP. Delayed initiation of appropriate antimicrobial therapy was\nassociated with a poorer outcome.\nDiscussion: Strategies that result in the timely administration of appropriate antimicrobial therapy should be investigated in an effort to reduce NP-associated mortality.

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.
