  • Title: Factors associated with death among adults <55 years of age hospitalized for community-acquired pneumonia.
    Author: Marrie TJ, Carriere KC, Jin Y, Johnson DH.
    Journal: Clin Infect Dis; 2003 Feb 15; 36(4):413-21. PubMed ID: 12567298.
    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.
