The purpose of this study was to provide information about the long-term sequelae of community-acquired pneumonia (CAP). The study was conducted in Edmonton, Alberta, Canada, from 2000 to 2002 with 3415 patients hospitalized with CAP in 6 hospitals. These patients were followed up prospectively and follow-up data were available from 96% with follow-up for ≥ 5 years in most. Patients were classified by the Pneumonia Severity Index (PSI) of Fine and colleagues at the time of hospitalization.
In all, 66% of subjects were 65 years of age or older and 63% had PSI scores of IV or V. The mortality data for 30 days, 1 year, and 4-6 years are summarized in the table .
The authors conclude that the long-term mortality following hospitalization for pneumonia correlates strongly with the initial PSI scores. They also suggest enhanced prevention strategies for those with PSI scores of IV and V at admission including closer follow-up based on these observations.
The author claims that, to his knowledge, this is the largest study of outcomes for hospitalized patients with pneumonia. The correlation between both short- and long-term mortality with the PSI score is quite striking.
