Abstract

fetched live from OpenAlex

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.

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.

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.
