Clinical aspects and prognostic factors in elderly patients hospitalised for community-acquired pneumonia.

The aims of this study were to determine the clinical and epidemiological characteristics of community-acquired pneumonia (CAP) in the elderly, to identify prognostic factors, and to establish a predictive model for mortality of CAP. Elderly patients with CAP admitted to "Carlos Haya" Hospital in Malaga, Spain, over a 36-month period were included. Multivariate analysis was used to identify prognostic factors from variables present on admission, from which a discrimination rule was constructed to predict mortality.
