Community‐Acquired Bacteremia in the Elderly: Analysis of One Hundred Consecutive Episodes

Abstract

A retrospective analysis was made of the records of 100 consecutive geriatric patients with community-acquired bacteremia, admitted to a suburban hospital. The most frequently identified tissue sources for these bacteremias were the urinary tract (34 percent), biliary tract (20 percent), and lungs (13 percent). In 11 percent of the patients, the tissue focus was not established. E. coli, Klebsiella species and Streptococcus pneumoniae were the most common organisms isolated, and they contributed to 73 percent of the bacteremias. Of the 100 patients, 26 succumbed to the infection. Clinical manifestations unique to the geriatric patient are described.
