Factors Associated with Death among Adults <55 Years of Age Hospitalized for Community‐Acquired Pneumonia
Bibliographic record
Abstract
An administrative database was used to study death occurring among adults aged 18-55 years who were hospitalized during the period from 1 April 1994 through 31 March 1999 for treatment of community-acquired pneumonia. In-hospital case-fatality rates for the first 10 days of hospitalization and overall were 2.1% and 3.2%, respectively, for 11,684 patient hospitalizations. Patient factors (age, sex, and comorbidity) were the most important associations with death. Aspiration provided the largest explanation of variance in deaths occurring during the first 10 days of hospitalization (odds ratio, 5.0; 95% confidence interval, 3.7-6.8). Busy hospitals (higher occupancy and higher number of daily admissions) were not associated with higher case-fatality rates. Bigger hospitals (metropolitan hospitals) had higher case-fatality rates, but this was more likely related to greater comorbidity and severity of pneumonia. Death due to community-acquired pneumonia among young and middle-aged adults is infrequent and is more related to the severity of pneumonia and to such risk factors as aspiration than to the manner in which the provision of care is organized.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
